    The legend has only retained from Marie Curie (1867-1934) the image of a hard and brilliant worker, pioneer in the radioactivity domain, and who awarded twice the Nobel Price. Behind the scientist, there is a women, Marya Salomea Sklodowska, the 'Polish', who was considered during some time as an 'alien', an 'atheistic intellectual', an 'emancipated women'. When she died alone in July 1934, after an exhausting life of labour, her funeral led to no official ceremony or speech. This small book summarizes the biography of the most famous female scientist in the world

    1942-01-01

    Marie Curie is a women who changed the face of science for all time, not just because of her discovery of the radioactive element Radium and her work with it, but because of her incredible strides forward in a such a male dominated world as laboratory science at the turn of the 19th century. This is the Madame Curie many people know but here is a biography written by her daughter Eve that shows her human side, in a way that can only be viewed and admired from a family member describing her as a caring mother, devoted and passionate wife. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive.

    Ferromagnetic materials such as nickel, iron, or cobalt lose the electron alignment that makes them attracted to a magnet when sufficient thermal energy is added. The temperature at which this change occurs is called the "Curie temperature," or "Curie point." Nickel has a Curie point of 627 K, so a candle flame is a sufficient…

    2007-04-01

    The year 2006 marked 100 years since the death of Pierre Curie. It is therefore appropriate that we remember his life and his work, which was cut short by his untimely death from an accident on the Pont Neuf, Paris, on April 19, 1906. He had already accomplished much during his life, both before the discovery of radium with Marie Curie, in work co-authored with his brother Jacques on piezoelectricity, and afterwards, when he published the results of several experimental studies with radium and radon. He came from a medical family, and his grandfather Pierre Curie was a famous homeopathic physician. He has, in print, unfairly been relegated to the background-his own scientific contributions having been overtaken by the fame of Marie Curie, probably because she outlived him by 28 years.

  8. CURIE: Cubesat Radio Interferometry Experiment

    2016-12-01

    The CUbesat Radio Interferometry Experiment (CURIE) is a proposed two-element radio interferometer, based on proven and developed digital radio receivers and designed to fit within a Cubesat platform. CURIE will launch as a 6U Cubesat and then separate into two 3U Cubesats once in orbit. CURIE measures radio waves from 0.1-19MHz, which must be measured from space, as those frequencies fall below the cutoff imposed by Earth's ionosphere. The principal science objective for CURIE is to use radio interferometry to study radio burst emissions from solar eruptive events such as flares and coronal mass ejections (CMEs) in the inner heliosphere, providing observations important for our understanding of the heliospheric space weather environment. The influence of space weather can be felt at Earth and other planets, as radiation levels increase and lead to auroral activity and geomagnetic effects. CURIE will be able to determine the location and size of radio burst source regions and then to track their movement outward from the Sun. In addition to the primary objective CURIE will measure the gradients of the local ionospheric density and electron temperature on the spatial scale of a few kilometers, as well as create an improved map of the radio sky at these unexplored frequencies. A space based radio interferometry observatory has long been envisioned, in orbit around the Earth or the Moon, or on the far side of the Moon. Beyond its important science objectives, CURIE will prove that the concept of a dedicated space-based interferometer can be realized by using relatively cheap Cubesats. CURIE will therefore not only provide new important science results but also serve as a pathfinder in the development of new space-based radio observation techniques for helio- and astro-physics.

  12. CURIE-TEMPERATURE "SLATER-PAULING CURVE"

    OpenAIRE

    Kakehashi, Y.; Hosohata, O.

    1988-01-01

    The systematic variation of the Curie-temperature "Slater-Pauling curve" has been explained for the first time on the basis of the finite-temperature theory of the local environment effect. The peculiarity of the Curie temperatures in Fe-V, Fe-Ni, and Ni-Mn alloys is elucidated by using the effective exchange couplings.

  13. Radium, Marie Curie and modern science.

    Science.gov (United States)

    Langevin-Joliot, H

    1998-11-01

    In 1898, the discovery of two new elements, polonium and radium, reawakened interest in the topic of uranic rays discovered 2 years before by H. Becquerel. Radioactivity, a name coined by Marie Curie, became a major research field for decades. The contrasting personalities of Pierre Curie, already a first-rank physicist, and of the young Marie Curie-Sklodowska as they undertook their common work are described. It is shown how a well-chosen quantitative method and a systematic approach combining physics and chemistry led to the discovery within less than 1 year. The special role of radium and the determination of its atomic weight by Marie Curie followed by her long-term program for accumulating pure radium salts are emphasized. The first woman with a full professorship at a French University, Marie Curie created and managed the Radium Institute.

  14. Fellowship trends of pathology residents.

    Science.gov (United States)

    Lagwinski, Nikolaj; Hunt, Jennifer L

    2009-09-01

    Recent changes in pathology residency education have included a decrease in the program length (from 5 years to 4 years for combined anatomic and clinical pathology training) and a national mandate for programs to assess 6 general competencies of trainees. These have undoubtedly led to changes in program curricula and in residents' desires to seek fellowship training. This study was designed to gather information about what residents are seeking from fellowship training programs. This study used an online survey to assess attitudes of residents in training programs toward fellowship training. The survey instrument had 26 questions pertaining to fellowship choices, motivations for pursuing fellowships, expectations of the fellowships, and postresidency concerns. There were 213 respondents from a mix of program types and representing each postgraduate year. Most residents will seek at least 1 or 2 fellowships after residency training. The most popular first-choice fellowship was surgical pathology (26%), followed by cytopathology (16%), hematopathology (15%), gastrointestinal pathology (10%), dermatopathology (8%), and forensic pathology (5%). The most common reasons for pursuing fellowship training were to "increase marketability" (43%) or to "become an expert in a particular area" (33%). Most trainees got their information about fellowship training programs from Internet sources. Fellowship programs will benefit from an optimally designed Web site because residents seek information predominantly from the Internet. Residents seeking fellowships are particularly concerned with selecting programs that provide job connections, an increase in their marketability, and the opportunity to develop diagnostic expertise.

  15. Pierre Curie: the anonymous neurosurgical contributor.

    2015-07-01

    Pierre Curie, best known as a Nobel Laureate in Physics for his co-contributions to the field of radioactivity alongside research partner and wife Marie Curie, died suddenly in 1906 from a street accident in Paris. Tragically, his skull was crushed under the wheel of a horse-drawn carriage. This article attempts to honor the life and achievements of Pierre Curie, whose trailblazing work in radioactivity and piezoelectricity set into motion a wide range of technological developments that have culminated in the advent of numerous techniques used in neurological surgery today. These innovations include brachytherapy, Gamma Knife radiosurgery, focused ultrasound, and haptic feedback in robotic surgery.

  16. Curie surface of Borborema Province, Brazil

    2016-06-01

    The Curie surface interpreted from magnetic data through spatial frequency domain techniques is used to provide information on the thermal structure of Borborema Province. The Borborema Province is part of the neoproterozoic collision of an orogenic system situated between the São Francisco-Congo and São Luís-West Africa cratons, which formed the Gondwana Supercontinent. The Curie surface of Borborema Province varies from 18 to 59 km, which reveals the complexity in the crustal composition of the study area. The thermal structure shows different crustal blocks separated by the main shear zones, which corroborates the evolution model of allochthonous terranes. The Curie surface signature for the west portion of Pernambuco Shear Zone may indicate processes of mantle serpentinization, once the Curie isotherm is deeper than Mohorovic discontinuity. In this region, the amplitude of Bouguer anomaly decreases, which corroborates long wavelength anomaly observed in the magnetic anomaly. We interpreted this pattern as evidence of the Brasiliano-Pan-Africano's subduction/collision event. Earthquakes in the region are concentrated mainly in shallow Curie surface regions (less resistant crust) and in transition zones between warm and cold blocks. We calculated the horizontal gradient of the Curie depth to emphasize the signature of contact between the thermal blocks. These regions mark possible crustal discontinuities, and have high correlation with orogenic gold occurrence in the study area.

  17. Fellowships in India

    Science.gov (United States)

    In an effort to encourage stronger research ties between India and the United States, the Indo-U.S. Subcommission on Education and Culture is offering 12 long-term and 9 short-term research fellowships in India in 1985 and 1986. The only requirement is that the applicants be U.S. citizens at the postdoctoral or equivalent postdoctoral level. The awards have no restrictions as to field of study, and because the program seeks to open new channels of communication between academic and professional groups in the two countries, those who have had little or no experience in India are especially encouraged to apply.The long-term fellowships are for 6 to 10 months, with a monthly allowance of $1500. Long-term fellows will also receive travel money and allowances for dependents. The short-term awards, for periods of 2 to 3 months, also offer a monthly payment of $1500. Funding for these fellowships is provided by the U.S. Information Agency, the National Science Foundation, the Smithsonian Institution, and the Government of India.

    2015-09-01

    This article establishes the rationale and development of an obstetrics and gynecology (OB/GYN) hospitalist fellowship program. The pool of OB/GYN hospitalists needs to be drastically expanded to accommodate the country's needs. Fellowship programs should provide extra training and confidence for recent resident graduates who want to pursue a hospitalist career. Fellowships should train physicians in a way that aligns their interests with those of the hospital with respect to patient care, teaching, and research. Research in the core measures should be a necessary component of the fellowship so as to provide long-term benefits for all stakeholders, including hospitals and patients.

  19. Pioneers of nuclear medicine, Madame Curie.

    Grammaticos, Philip C

    2004-01-01

    Among those who have made important discoveries in the field of radioactivity and thus helped in the development of nuclear medicine as an identical entity are: Heinrich Hertz who in 1886 demonstrated the existence of radiowaves. In 1895 Wilhelm Röntgen discovered the X-rays. In 1896 H. Becquerel described the phenomenon of radioactivity. He showed that a radioactive uranium salt was emitting radioactivity which passing through a metal foil darkened a photographic plate. An analogous experiment performed by S.Thomson in London was announced to the president of the Royal Society of London before the time H.Becquerel announced his discovery but Thomson never claimed priority for his discovery. Muarie Sklodowska Curie (1867-1934) was undoubtedly the most important person to attribute to the discovery of radioactivity. In 1898 she discovered radium as a natural radioactive element. This is how she describes the hard time she had, working with her husband Pierre Curie (1859-1906) for the discovery of radium and polonium: "During the first year we did not go to the theater or to a concert or visited friends. I miss my relatives, my father and my daughter that I see every morning and only for a little while. But I do not complain...". In presenting her discovery of radium, Madame Curie said: " ...in the hands of a criminal, radium is very dangerous. So we must often ask ourselves: will humanity earn or lose from this discovery? I, myself belong to those who believe the former...". The notebooks that Madame Curie had when she was working with radium and other radioactive elements like polonium, thorium and uranium are now kept in Paris. They are contaminated with radioactive materials having very long half-lives and for this reason anyone who wishes to have access to these notes should sign that he takes full responsibility. There are some more interesting points in Madame Curie's life which may not be widely known like: Although her full name is Maria Sklodowska-Curie

  2. Women who Worked with Marie Curie.

    Science.gov (United States)

    Pigeard-Micault, Natalie

    2015-06-01

    Marie Curie directed a research laboratory for 28 years. Between 1906 and 1934, forty five women worked under her guidance. Some were, and are, well-known in their own countries as their first woman full professor such as Ellen Gleditsch or Margaret von Wrangel, but for twenty eight of them, who were often French, nothing has ever been written. The strong presence of women in Marie Curie's laboratory has often been highlighted and has been considered as an exception, and the result of deliberate choice. Of course, these women did not choose this workplace by accident. They knew its director was a woman, a laureate of one, and after 1911, two Nobel Prizes, who was leading a well-equipped laboratory with an important radioactive source. But how did Marie Curie selected her collaborators among the many applications she received? Was her choice influenced by gender? A prosopographical research based on genealogical researches and new sources explains this presence contextually and sheds light on several questions : where did these women come from, what were their social and geographic origins, did they occupy any specific cultural or technical area inside Curie's lab, what future did they have after the laboratory? Through their lives, we can question the existence, or not, of a one profile of the female researcher in scientific areas in France.

    2008-07-01

    In Paris in 1894, two young physicists fall in love: Marie Sklodowska and Pierre Curie. They get married and make great contributions to science, research radioactivity and discover new chemical elements. The marriage of Marie and Pierre Curie is quite modern: They work together as equals, share their thoughts and pursue their plans together as partners. They share an absolute interest in science, a love of nature, and a sceptic attitude towards the sophisticated society of the Belle Epoque. They are together 24 hours a day with hardly ever any disagreement. Whenever one of them is ill - which is quite often because of the high level of radioactivity in their laboratory -, the other will nurse him or her. After only twelve years of mutual love, Pierre Curie dies. Marie raises their two daughters on her own and continues her research. In 1911, she will be the first scientist that ever gets a second Nobel Prize. (orig.) [German] Im Paris des Jahres 1894 verlieben sich zwei junge Physiker: Marie Sklodowska und Pierre Curie. Sie heiraten und leisten gemeinsam Grosses fuer die Wissenschaft, erforschen die Radioaktivitaet und entdecken neue chemische Elemente. Zusammen erhalten sie den Nobelpreis. Marie und Pierre Curie fuehren eine Ehe, die ihrer Zeit weit voraus ist: Sie arbeiten gleichberechtigt miteinander, teilen ihre Gedanken und verfolgen ihre Plaene gemeinsam. Beiden eigen ist die absolute wissenschaftliche Neugier, die Liebe zur Natur und die Skepsis gegenueber der mondaenen Gesellschaft der Belle Epoque. Fast jeden Tag sind sie rund um die Uhr zusammen, dabei gibt es selten Spannungen. Wenn einer von beiden gesundheitliche Probleme hat - und das haben sie wegen der radioaktiven Belastung im Labor oft - ist der andere fuer ihn da und pflegt ihn. Nach nur zwoelf gemeinsamen Jahren der Liebe und Arbeit stirbt Pierre Curie.

    Marie Curie was a remarkable woman whose discoveries broke new ground in physics and chemistry and also opened the door for advances in engineering, biology, and medicine. She broke new ground for women in science: she was, for example, the first woman to receive a doctor of science degree in France, the first woman to win Nobel Prize, the first woman to lecture at the Sorbonne, the first person to win two Nobel Prizes, and the first Nobel Laureate whose child also won a Nobel Prize. Her life offers insights into the changing role of women in science and academia over the past century. It also offers examples of many ways in which scientists can, and should, work to improve the educational programs and career opportunities available to those who follow in their footsteps.

    Wielogórski, Zbigniew

    2012-01-01

    For many reasons the year 1898 was unusual for Maria Skłodowska-Curie and her husband. After defining the subject of the doctoral thesis and choosing Henri Becqerel as thesis supervisor, Maria started intensive experimental work. In the allotted room called storeroom, in conditions that were far too inadequate, they managed to put up a unique measuring equipment composed of instruments whose originator was Pierre Curie. In the ionization chamber and in the piezoelectric quartz charges formed, whose mutual neutralization was shown by the quadrant electrometer. Ionization current, which was measured quantitatively, was proportional to the radiation of the sample. Studying many elements, their compounds and minerals enabled Maria to state that uranium is not the only element endowed with the power of radiation; the second one turned out to be thorium. Anomaly detected in the radiation of uranium minerals made it possible for Maria to draw an extremely important conclusion: radioactive uranium and thorium are not the only elements endowed with such an attribute. Pitchblende, which was studied by the Curie couple, had to contain also other radioactive substances. Gustave Bémont also participated in the chemical analysis of the uranium ore and it is worth reminding that he was involved in the discovery of polonium and uranium. The phenomenon of radioactivity couldn't have been explained if it was not for the sources of strong radioactivity. Those sources undoubtedly could have been the discovered elements but their scanty content in the uranium ore made their isolation very difficult and laborious. Access to industrial remains after procession of pitchblende from Jachymov (Sankt Joachimstahl), obtained owing to the mediation of Eduard Suess, provided the source of this raw material. From it, in a shack also called le hangar, the Curie couple isolated the first samples of the radium salt. This element, later extracted by discoverers on a grand scale and handed over in a

    2012-12-01

    The Early Career Fellowship program was established in 2005 to facilitate the integration of outstanding early career planetary science researchers into established research funding programs by providing tools and experience useful to maintain a successful research program. Executing a successful research program requires a few key elements such as: successful proposal writing; adequate (paid) research time; management of a laboratory; collaboration and networking; frequent and high-quality publications; and adequate start-up equipment funds. These elements may be particularly critical for early career researchers searching for a tenure- track or equivalent position. The Early Career Fellowship program recognizes the importance of these skills and provides extra funding and resources to begin a successful research program. For consideration into The Early Career Fellowship program, the candidate needs to be the P. I. or Science P.I. of a funded research proposal from one of the participating R&A program areas, be within 7 years of earning a PhD, hold a non-tenure track position, and indicate the early career candidacy when submitting the research proposal. If the research proposal is funded and the discipline scientist nominates the candidate as an early career fellow, the candidate is then considered a Fellow and eligible to propose for Step 2. Upon obtaining a tenure-track equivalent position the Fellow submits a Step 2 proposal for up to one hundred thousand dollars in start-up funds. Start-up funds may be used for salary; undergraduate and/or graduate research assistants; supplies and instrument upgrades; travel to conferences, meetings, and advisory groups; time and travel for learning new skills; publication page charges; books and journal subscriptions; computer time and/or specialized software; and other justified research-specific needs. The early career fellowship program provides resources that a more established scientist would have acquired allowing

The purpose of our study was to determine a predominant learning style within otolaryngology fellowships and to identify any differences between otolaryngology fellows and residents. We conducted a survey of otolaryngology fellows at 25 otolaryngology fellowship programs accredited by the Accreditation Council for Graduate Medical Education. We emailed Kolb's Learning Style Index version 3.1 to 16 pediatric otolaryngology (PO) and 24 otology/neurotology (ON) fellows. This index is a widely used 12-item questionnaire. The participants answered each item in the questionnaire as it applied to their preferred learning style: accommodating, converging, diverging, or assimilating. Results were then analyzed and compared between each subspecialty and the previously reported preferred styles of otolaryngology residents. Ten PO and 20 ON fellows completed the survey, with an overall response rate of 75%. PO and ON fellows (60% of each group) preferred a learning style that was "balanced" across all four styles. For ON fellows, 35% preferred converging and 5% preferred accommodating styles. For PO fellows, converging and accommodating styles accounted for 20% each. It was previously reported that 74.4% of otolaryngology residents prefer either converging or accommodating styles. We believe that the fellowship training environment calls for fellows to use more than one learning style to become proficient physicians, hence the trend toward potentially developing a balanced style when at this level.

    Ferromagnetic resonance properties of F1/f/F2/AF multilayers, where weakly ferromagnetic spacer f is sandwiched between strongly ferromagnetic layers F1 and F2, with F1 being magnetically soft and F2-magnetically hard due to exchange pinning to antiferromagnetic layer AF, are investigated. Spacer-mediated exchange coupling is shown to strongly affect the resonance fields of both F1 and F2 layers. Our theoretical calculations as well as measurements show that the key magnetic parameters of the spacer, which govern the ferromagnetic resonance in F1/f/F2/AF, are the magnetic exchange length (Λ), effective saturation magnetization at T  =  0 (m0) and effective Curie temperature (T(C)(eff)). The values of these key parameters are deduced from the experimental data for multilayers with f  =  Ni(x)Cu(100-x), for the key ranges in the Ni-concentration (x = 54 ÷ 70 at. %) and spacer thickness (d = 3 ÷ 6 nm). The results obtained provide a deeper insight into thermally-controlled spin precession and switching in magnetic nanostructures, with potential applications in spin-based oscillators and memory devices.

    Great names in science represent an inexhaustible source and richness of inspiration, satisfaction and consolation, a moving and victorious force. Throughout her exemplifying life, Maria Sklodowska remained modest but with a keen sense of humor, of an outstanding style, a mine of knowledge and experience, of innovative ideas and a rich inner life. Full of love, of passion to give and to share, of natural optimism, mixed with a light melancholy, so typical for sages. She vehemently defended the love of scientific research, of the spirit of adventure and entrepreneurship and fought for international culture, for the protection of personality and talent. Maria Sklodowska left her passion to science, her dedication to work including education and training of young people, her passionate adherence to her family, her belief in her friends, her pure and profound humanity and warmth! The paper should be a homage to her, an appreciation of her work over the years, but not less a correspondence, a conversation with her! On the other hand, the present solemn occasion resuscitates the personalities of Maria and Pierre Curie and their work, in particular of Maria Sklodowska in her own native land! In this manner, it truly contributes to her immortality!

    An established hospital-based nursing research fellowship program was transformed into an evidence-based practice fellowship despite its previous high satisfaction ratings from nursing leaders and nurse fellow participants. The faculty for the fellowship program determined that the long-term outcomes of the research program were insufficient in light of the hospital resources committed to the fellowship program. An evidence-based practice approach was then created in anticipation that greater short-term and more sustained longer-term benefits for the hospital would be realized. The transformation of the fellowship and the short-term outcomes are described.

    Biographies of scientists occupy a liminal space, highly popular with general readers but questioned in academia. Nonetheless, in recent years, historians of science have not only embraced the genre with more enthusiasm and less guilt, they have also turned to the metabiography in order to renew the study and story of scientists' roles. This essay focuses on Marie Curie, the world's most famous female scientist, in order to unpack some of the theoretical and methodological claims of the science biography, and especially to address the sexing mechanisms at play in the construction of the biographical subject. Pierre Curie (1923), Marie's biography of her husband Pierre, paid tribute to her dead husband and collaborator, but also allowed Curie a legitimate outlet to construct her own persona and legacy. Categories such as personhood, person, and persona are not only central to the biography genre but also are essential to the sense of self and self-fashioning of scientists. Looking at how Marie Curie negotiated these categories in Pierre Curie not only gives new insight into Curie's self-fashioning strategies but may also shed some light on the more general analytical lacunae of the science biography.

  2. Referrals to the Marie Curie nursing service in North Yorkshire.

    District and Marie Curie nurses participated in a small-scale study to describe referrals to a Marie Curie service in one English health district over a 3-month period. The number of new patients referred was small; they were geographically clustered and had widely differing life expectancies. Anecdotal reports of difficulties with the 'Nurselink' referral system were not confirmed, and in situations where the system was in operation, Marie Curie nurses were more likely to speak directly to the referring nurse. The most frequently cited reason for referral was general nursing needs; however, Marie Curie nurses felt that they were most often involved to provide family support. These findings suggest that there may not be a shared understanding of the Marie Curie nurse's role, and that equity in community palliative nursing care merits examination. Defining and publicizing the role of the Marie Curie nurse, providing guidance for referrals and prioritizing communication between professionals are proposed not only to enhance the service locally but to ensure that the service is available to all. This article illustrates the value of research to identify ways to improve service delivery.

    Marie Curie was awarded the Nobel Prize in 1903 and in 1911. Also her daughter, Irene Joliot-Curie, received a Nobel Prize for science in 1935. In this book an overview is given of the academic world at that time: limited access to universities for women, the carriers of both women in physics and their pioneering research and discoveries, the refusal of Marie Curie by the French Academy of Sciences, the awarding of the Nobel Prize and the assignment of Irene Joliot-Curie as the first female minister in France, the impact of the two World Wars, their married and private lives and the constant smear campaign of the press against both women. The lives and works of both women are hold against the light of the present position of women in physical sciences. [Dutch] In 1903, precies honderd jaar geleden, ontving Marie Curie als eerste vrouw de Nobelprijs voor de Wetenschap, gevolgd door een tweede Nobelprijs in 1911. Ook haar dochter Irene Joliot-Curie kreeg de Nobelprijs voor de wetenschap in 1935. Marie and Irene Curie schetst een breed beeld van de academische wereld waarin beide vrouwen zich bewogen: de beperkte toegang van vrouwen tot de universiteit, hun carrisres in de natuurkunde en baanbrekende ontdekkingen, de afwijzing van Marie door de Franse Academie des Sciences, de toekenning van de Nobelprijs en de benoeming van Irene als eerste vrouwelijke minister in Frankrijk, de invloed van de twee Wereldoorlogen, hun huwelijks- en priveleven en de niet aflatende hetze van de pers tegen beiden. In de door mannen gedomineerde wereld van de natuurwetenschappen liep de uitzonderingspositie van beide vrouwen als rode draad door hun curieuze levens. Het leven en werk van de Curies wordt geactualiseerd door deze tegen het licht te houden van de huidige positie van vrouwen in de natuurwetenschappen. Het bereiken van de top van de wetenschap door vrouwen blijkt nog steeds uitzonderlijk.

    The Large Synoptic Survey Telescope Corporation (LSSTC) Data Science Fellowship Program (DSFP) is a unique professional development program for astronomy graduate students. DSFP students complete a series of six, one-week long training sessions over the course of two years. The sessions are cumulative, each building on the last, to allow an in-depth exploration of the topics covered: data science basics, statistics, image processing, machine learning, scalable software, data visualization, time-series analysis, and science communication. The first session was held in Aug 2016 at Northwestern University, with all materials and lectures publicly available via github and YouTube. Each session focuses on a series of technical problems which are written in iPython notebooks. The initial class of fellows includes 16 students selected from across the globe, while an additional 14 fellows will be added to the program in year 2. Future sessions of the DSFP will be hosted by a rotating cast of LSSTC member institutions. The DSFP is designed to supplement graduate education in astronomy by teaching the essential skills necessary for dealing with big data, serving as a resource for all in the LSST era. The LSSTC DSFP is made possible by the generous support of the LSST Corporation, the Data Science Initiative (DSI) at Northwestern, and CIERA.

    This document contains the lectures of the Joliot-Curie International School of Nuclear Physics held at Maubuisson, France on 8-13 September 1997. The following lectures of nuclear interest were given: The N-body problem (relativistic and non-relativistic approaches); The shell model (towards a unified of the nuclear structure); Pairing correlations in extreme conditions; Collective excitations in nuclei; Exotic nuclei (production, properties and specificities); Exotic nuclei (halos); Super and hyper deformation (from discrete to continuum, from EUROGAM to EUROBALL); and The spectroscopy of fission fragments. Important new facts are reported and discussed theoretically, concerning the nuclei in high excitation and high states and of the nuclei far off stability. Important technical achievements are reported among which the production of radioactive beams, sophisticated multi-detectors as well as significant advances in the nuclear theoretical methods. The double goal of training of young researchers and of permanent formation and information of the older ones seems to have been reached

Methods: Regional anesthesia fellowship directors across the world were asked to complete a comprehensive survey that detailed the range of educational and practical experience and attitudes as well as assessment procedures offered in their programs. Results: The survey response rate was 66% (45/68. Overall, the range of activities and the time and resources committed to education during fellowships is encouraging. A wide range of nerve block experience is reported with most programs also offering acute pain management, research, and teaching opportunities. Only two-thirds of fellowships provide formal feedback. This feedback is typically a formative assessment. Conclusion: This is the first survey of regional anesthesia fellowship directors, and it illustrates the international scope and continuing expansion of education and training in the field. The results should be of interest to program directors seeking to benchmark and improve their educational programs and to faculty involved in further curriculum development.

    Background: Research productivity is considered an important factor in academic advancement in sports medicine. No study to date has evaluated academic productivity and correlates of academic rank for sports medicine fellowship faculty. Purpose: To describe the academic productivity of American Orthopaedic Society for Sports Medicine (AOSSM) fellowship program faculty and to determine the association between academic productivity, fellowship characteristics, and academic rank. Study Design: Descriptive epidemiology study. Methods: Characteristics of orthopaedic sports medicine fellowship programs were obtained from the AOSSM and program websites. Metrics of academic productivity (Hirsch index [h index], I-10 index, publications, citations, and number of publications in several journals) were obtained from Scopus. Statistical analyses were conducted to determine whether academic productivity differs with fellowship attributes and academic rank. Results: A total of 90 AOSSM sports medicine fellowship programs with 610 associated faculty members were identified. Faculty were predominantly male (94%), at academic medical centers (74%), members of AOSSM (71%), and sports medicine–fellowship trained (84%). Faculty had a median of 18 (range, 0-684) publications overall, including a median of 3 (range, 0-161) publications since 2012. All measures of academic productivity were significantly higher among faculty employed at academic medical centers compared with those not employed at academic centers (P Research productivity was higher among faculty employed at academic centers in the Northeast and Midwest regions and at programs with a larger number of fellows.

    Background: A substantial number of orthopaedic surgeons apply for sports medicine fellowships after residency completion. The Internet is one of the most important resources applicants use to obtain information about fellowship programs, with the program website serving as one of the most influential sources. The American Orthopaedic Society for Sports Medicine (AOSSM), San Francisco Match (SFM), and Arthroscopy Association of North America (AANA) maintain databases of orthopaedic sports medicine fellowship programs. A 2013 study evaluated the content and accessibility of the websites for accredited orthopaedic sports medicine fellowships. Purpose: To reassess these websites based on the same parameters and compare the results with those of the study published in 2013 to determine whether any improvement has been made in fellowship website content or accessibility. Study Design: Cross-sectional study. Methods: We reviewed all existing websites for the 95 accredited orthopaedic sports medicine fellowships included in the AOSSM, SFM, and AANA databases. Accessibility of the websites was determined by performing a Google search for each program. A total of 89 sports fellowship websites were evaluated for overall content. Websites for the remaining 6 programs could not be identified, so they were not included in content assessment. Results: Of the 95 accredited sports medicine fellowships, 49 (52%) provided links in the AOSSM database, 89 (94%) in the SFM database, and 24 (25%) in the AANA database. Of the 89 websites, 89 (100%) provided a description of the program, 62 (70%) provided selection process information, and 40 (45%) provided a link to the SFM website. Two searches through Google were able to identify links to 88% and 92% of all accredited programs. Conclusion: The majority of accredited orthopaedic sports medicine fellowship programs fail to utilize the Internet to its full potential as a resource to provide applicants with detailed information about the

    A fulfillment of Curie's law in magnetic fluids provides an option of their thermometric applications to measure thermodynamic temperature. On the other hand, it was shown elsewhere that the initial magnetic susceptibility χ of magnetic fluids follows Curie-Weiss's law rather than Curie's law. To obtain its values, use was made of the formula χ = M/N0, where M is magnetization, and N0 is the external magnetic field strength without any specimen. This work deals with investigations of the dependence of magnetic susceptibility of magnetic fluid on temperature for the cases where its values are found via the following formulas: 1) χ = M/N0, and 2) χ = Mμ0/M, where M is the magnetic field induction inside the specimen. It is found that in the first case the temperature dependence of χ obeys Curie-Weiss's law while in the second case - Curie's law. The reason for this results from the fact that induction M acting on the particles of magnetic fluid is noticeably higher than that of the external field, M0.

    A resolution of the 63rd Assembly of the United Nations proclaimed the year 2011 as the International Year of Chemistry. The coordinators of the event are UNESCO and the International Union of Pure and Applied Chemistry (IUPAC). The patroness of this event is Marie Curie, nee Sklodowska. Among women scientists, she was the first recipient of the Novel Prize, and among all scientists, she is the only one who has received this award in different scientific fields (in 1903 in the field of physics with Pierre Curie and Henri Becquerel, in 1911 in the field of chemistry). Considering the former Polish nationality of Marie Curie, the year 2011 has been proposed by the Polish Parliament as her year, using the name Maria Sklodowska Curie, under which she is known in Poland. Celebrating the International Year of Chemistry is a good opportunity to remember the importance of the work of Maria Sklodowska Curie for the emergence and development of many fields of science. This article is an attempt to present a view of science, as taught through modern applications of the radiation chemistry of polymetric materials and radiation sterilization. Although the real development of both ''cold'' sterilization and polymer technology occurred in the 1950's long after the death of Marie Curie Sklodowska, the original ideas go back to ther work performed in the 1920s. Sometimes, and that is the present case, a single scientist creates a new field, in spite of the fact that at the time of discovery there are no applications. The parallel development of other branches of science and technology helps the application of the original idea. (orig.)

  13. Size and shape effects on Curie temperature of ferromagnetic nanoparticles

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    A simplified model was developed to describe the Curie temperature suppression of ferromagnetic nanoparticles. Based on a size and shape dependent model of cohesive energy, the critical temperature variations of ferromagnetic nanoparticles were deduced. It is predicted that the Curie temperature of nanoparticles depends on both size and shape conditions, among which the temperature suppression is strongly influenced by the particle size and the shape effect is comparably minor. The calculation values for freestanding nanoparticles are in good agreement with other theoretical model and the experimental results. The model is also potential for predictions for the nanoparticles embedded in different substrates.

    The American Council of Graduate Medical Education, which oversees much of postgraduate medical education in the United States, has championed the concept of "milestones," standard levels of achievement keyed to particular time points, to assess trainee performance during residency. To develop a milestones document for the American Society for Dermatologic Surgery (ASDS) Cosmetic Dermatologic Surgery (CDS) fellowship program. An ad hoc milestone drafting committee was convened that included members of the ASDS Accreditation Work Group and program directors of ASDS-approved Cosmetic Dermatologic Surgery (CDC) fellowship training programs. Draft milestones were circulated through email in multiple rounds until consensus was achieved. Thirteen milestones were developed in the 6 Accreditation Council for Graduate Medical Education (ACGME) competency areas, with 8 of these being patient-care milestones. Additional instructions for milestone administration more specific to the CDS fellowship than general ACGME instructions were also approved. Implementation of semiannual milestones was scheduled for the fellowship class entering in July 2018. Milestones are now available for CDS fellowship directors to implement in combination with other tools for fellow evaluation.

    Maria Skłodowska Curie left us a great legacy. Her discovery of polonium and radium was incomparably greater than the mere discovery of new elements. Its significance lay in the discovery of a new form of matter, namely radioactive one, but also in her unveiling of the internal property of its atoms. Subsequently emitted radiation went on to play the role of a "natural accelerator" for both scientific research and in medical radiotherapy. It was thanks to these discoveries that the field of nuclear physics arose just a few decades later. As importantly the work of Maria Curie Skłodowska during the Great War demonstrated how important pure scientific discovery can be for society and its welfare.

    The ESR signal of lithium intercalated MCMB can be well simulated by combination of a Lorentz curve and a Gauss curve. The ESR intensity of the Lorentz component is essentially independent of temperature while the Gauss component shows a linear change with the reciprocal of temperature, indicative of Pauli spin and Curie spin, respectively. The former is probably associated with the ordered (graphitized) structures while the latter with the disordered structures in the sample.

    Radiology fellowship training has evolved from being an uncommon option to being a near requisite for post-training employment in the United States. A subset of fellows elect to pursue second fellowships with potentially substantial implications on both the private sector and academic radiology workforce. The purpose of this study was to assess the proportion of current radiology fellows pursuing multiple years of post-residency fellowship training. After obtaining IRB approval, an anonymous web-based survey was emailed to 1,269 radiology fellows listed as "completing fellowship" in the American College of Radiology database in June 2014. Questions were asked regarding current fellowship training, post-fellowship employment plans, and individual experience pursuing employment. Results were analyzed using the survey analytical software. There were 219 responses received, representing a 17.3% response rate. Ten-percent of respondents were currently completing their second radiology fellowship. Of those completing their first year of fellowship training, 11% indicated plans to complete a second radiology fellowship. This survey provides a snapshot of the percentage of radiology trainees who pursue a second year of fellowship training, currently in the range of 10%. Pursuing a second radiology fellowship may represent a safety net to a substantial subset of fellows who are not able to obtain satisfactory employment following training. Academic programs who rely heavily on fellows should be aware of the proportion of fellows pursuing two fellowships and should be prepared to adapt should this change over time.

    Marie Sklodowska-Curie, an extraordinary woman, a Polish scientist who lived and worked in France, led to the development of nuclear energy and the treatment of cancer. She was the laureate of two Nobel Prizes, the first woman in Europe who obtained the degree of Doctor of Science and opened the way for women to enter fields which had been previously reserved for men only. As a result of her determination and her love of freedom, she has become an icon for many female scientists active in radiation sciences. They are successors of Maria Curie and without the results of their work, improvement in radiation oncology will not be possible. Many of them shared some elements of Maria Curie's biography, like high ethical and moral standards, passionate dedication to work, strong family values, and scientific collaboration with their husbands. The significance of Tikvah Alper, Alma Howard, Shirley Hornsey, Juliana Denekamp, Helen Evans, Eleanor Blakely, Elizabeth L. Travis, Fiona Stewart, Andree Dutreix, Catharine West, Peggy Olive, Ingela Turesson, Penny Jeggo, Irena Szumiel, Eleonor Blakely, Sara Rockwell and Carmel Mothersill contribution to radiation oncology is presented. All the above mentioned ladies made significant contribution to the development of radiotherapy (RT) and more efficient cancer treatment. Due to their studies, new schedules of RT and new types of ionizing radiation have been applied, lowering the incidence of normal tissue toxicity. Their achievements herald a future of personalized medicine.

    The pediatric hospital medicine (PHM) core competencies were established in 2010 to identify the specific knowledge base and skill set needed to provide the highest quality of care for hospitalized children. The objectives of this study were to examine the perceived core competency achievements of fellowship-trained and non-fellowship-trained early career pediatric hospitalists and identify perceived gaps in our current training models. An anonymous Web-based survey was distributed in November 2013. Hospitalists within 5 years of their residency graduation reported their perceived competency in select PHM core competencies. χ(2) and multiprobit regression analyses were utilized. One hundred ninety-seven hospitalists completed the survey and were included; 147 were non-fellowship-trained and 50 were PHM fellowship graduates or current PHM fellows. Both groups reported feeling less than competent in sedation and aspects of business practice. Non-fellowship-trained hospitalists also reported mean scores in the less than competent range in intravenous access/phlebotomy, technology-dependent emergencies, performing Plan-Do-Study-Act process and root cause analysis, defining basic statistical terms, and identifying research resources. Non-fellowship-trained hospitalists reported mean competency scores greater than fellowship-trained hospitalists in pain management, newborn care, and transitions in care. Early career pediatric hospitalists report deficits in several of the PHM core competencies, which should be considered when designing PHM-specific training in the future. Fellowship-trained hospitalists report higher levels of perceived competency in many core areas. © 2015 Society of Hospital Medicine.

    To present a model for integrated global health fellowships in plastic surgical residency training. National surveys have found that North American surgical residents have significant interest in international training. While global health training opportunities exist, less than a third of these are housed within surgical residency programs; even fewer are designed specifically for plastic surgery residents. The Tsao Fellowship was created through a partnership between Operation Smile, Children's Hospital Los Angeles, Shriners Hospital for Children, and the University of Southern California. Designed for Accreditation Council for Graduate Medical Education accredited plastic surgery residents between their third and fourth years of residency, the fellowship curriculum is completed over 24 months and divided into 3 areas: clinical research, international reconstructive surgery fieldwork, and the completion of a Master of Science in Clinical and Biomedical Investigations. The Tsao Fellowship has matriculated 4 fellows: 3 have graduated from the program and 1 is in the current cycle. Fellows completed 4 to 7 international missions each cycle and have performed an aggregate total of 684 surgical procedures. Each fellow also conducted 2 to 6 research projects and authored several publications. All fellows continue to assume leadership roles within the field of global reconstructive surgery. Comprehensive global health fellowships provide invaluable opportunities beyond surgical residency. The Tsao Fellowship is a model for integrating international surgical training with global health research in plastic surgical residency that can be applied to other residency programs and different surgical specialties.

  10. American diagnostic radiology residency and fellowship programmes.

    Rumack, Carol Masters

    2011-03-01

    American Diagnostic Radiology Residency and Fellowship programmes are Graduate Medical Education programmes in the United States (US) equivalent to the Postgraduate Medical Education programmes in Singapore. Accreditation Council for Graduate Medical Education (ACGME) accredited diagnostic radiology residency programmes require 5 years total with Post Graduate Year (PGY) 1 year internship in a clinical specialty, e.g. Internal Medicine following medical school. PGY Years 2 to 5 are the core years which must include Radiology Physics, Radiation Biology and rotations in 9 required subspecialty rotations: Abdominal, Breast, Cardiothoracic, Musculoskeletal, Neuroradiology, Nuclear and Paediatric Radiology, Obstetric & Vascular Ultrasound and Vascular Interventional Radiology. A core curriculum of lectures must be organised by the required 9 core subspecialty faculty. All residents (PGY 2 to 4) take a yearly American College of Radiology Diagnostic In-Training Examination based on national benchmarks of medical knowledge in each subspecialty. Because the American Board of Radiology (ABR) examinations are changing, until 2012, residents have to take 3 ABR examinations: (i) ABR physics examination in the PGY 2 to 3 years, (ii) a written examination at the start of the PGY 5 year and (iii) an oral exam at the end of the PGY 5 year. Beginning in 2013, there will be only 2 examinations: (i) the physics and written examinations after PGY 4 will become a combined core radiology examination. Beginning in 2015, the final certifying examination will be given 15 months after the completion of residency. After residency, ACGME fellowships in PGY 6 are all one-year optional programmes which focus on only one subspecialty discipline. There are 4 ACGME accredited fellowships which have a Board Certifi cation Examination: Neuroradiology, Nuclear, Paediatric and Vascular Interventional Radiology. Some ACGME fellowships do not have a certifying examination: Abdominal, Endovascular

    For students interested in enriching their interprofessional competencies beyond those required and offered by their academic programs, an elective interprofessional education fellowship can serve that need. We designed a fellowship for students linking a conceptual framework grounded in adult learning principles. During the fellowship, students progress through three levels of learning as they acquire, apply, and demonstrate interprofessional collaborative knowledge and skills; fellowship activities are self-directed. A content analysis of students' fellowship summary reports sought to determine the effectiveness of the fellowship as a learning experience to acquire interprofessional collaborative competences. Results indicated that students most consistently report competencies associated with acquisition of values and ethics for interprofessional practice, roles/responsibilities, and teams/teamwork; interprofessional communication was implied. All students expressed commitment to interprofessional collaborative behavior when in practice. Based on the results from this study, this fellowship structure may serve as a model for other institutions to adapt and implement for best practice and best fit.

    This paper proposes a conditional Curie-Weiss model as a model for opinion formation in a society polarized along two opinions, say opinions 1 and 2. The model comes with interaction strength $\\beta>0$ and bais $h$. Here the population in question is divided into three main groups, namely: Group one consisting of individuals who have decided on opinion 1. Let the proportion of this group be given by $s$. Group two consisting of individauls who have chosen opinion 2. Let $r$ be their proportion. Group three consisting of individuals who are yet to decide and they will decide based on their environmental conditions. Let $1-s-r$ be the proportion of this group. We show that the specific magnetization of the associated conditional Curie-Weiss model has a first order phase transition (discontinuous jump in specific magnetization) at $\\beta^*=\\left(1-s-r\\right)^{-1}$. It is also shown that not all the discontinuous jumps in magnetization will result in phase change. We point out how an extention of this model could...

    Hyperthermia induced by the heating of magnetic particles (MPs) in alternating magnetic field receives a considerable attention in cancer therapy. An interesting development in the studies dedicated to magnetically based hyperthermia is the possibility to control the temperature using MPs with selective magnetic absorption properties. This paper analyzes the temperature field determined by the heating of MPs having low Curie temperature (a FeCrNbB particulate system) injected within a malignant tissue, subjected to an ac magnetic field. The temperature evolution within healthy and tumor tissues was analyzed by finite element method simulations in a thermo-fluid model. The cooling effect produced by blood flowing in blood vessels was considered. This effect is intensified at the increase of blood velocity. The FeCrNbB particles, having the Curie temperature close to the therapeutic range, transfer the heat more homogeneous in the tumor keeping the temperature within the therapeutic range in whole tumor volume. Having the possibility to automatically control the temperature within a tumor, these particle type opens new research horizons in the magnetic hyperthermia.

    The Faculty Fellowship program was revived in the summer of 2015 at NASA Marshall Space Flight Center, following a period of diminished faculty research activity here since 2006 when budget cuts in the Headquarters' Education Office required realignment. Several senior Marshall managers recognized the need to involve the Nation's academic research talent in NASA's missions and projects to the benefit of both entities. These managers invested their funds required to establish the renewed Faculty Fellowship program in 2015, a 10-week residential research involvement of 16 faculty in the laboratories and offices at Marshall. These faculty engineers and scientists worked with NASA collaborators on NASA projects, bringing new perspectives and solutions to bear. This Technical Memorandum is a compilation of the research reports of the 2015 Marshall Faculty Fellowship program, along with the Program Announcement (appendix A) and the Program Description (appendix B). The research touched on seven areas-propulsion, materials, instrumentation, fluid dynamics, human factors, control systems, and astrophysics. The propulsion studies included green propellants, gas bubble dynamics, and simulations of fluid and thermal transients. The materials investigations involved sandwich structures in composites, plug and friction stir welding, and additive manufacturing, including both strength characterization and thermosets curing in space. The instrumentation projects involved spectral interfero- metry, emissivity, and strain sensing in structures. The fluid dynamics project studied the water hammer effect. The human factors project investigated the requirements for close proximity operations in confined spaces. Another team proposed a controls system for small launch vehicles, while in astrophysics, one faculty researcher estimated the practicality of weather modification by blocking the Sun's insolation, and another found evidence in satellite data of the detection of a warm

  2. Curie law for systems described by kappa distributions

    Livadiotis, George

    2016-01-01

    We derive the magnetization of a system, Pierre Curie's law, for paramagnetic particles out of thermal equilibrium described by kappa distributions. The analysis uses the theory and formulation of the kappa distributions that describe particle systems with a non-zero potential energy. Among other results, emphasis is placed on the effect of kappa distribution on the phenomenon of having strong magnetization at high temperatures. At thermal equilibrium, high temperature leads to weak magnetization. Out of thermal equilibrium, however, strong magnetization at high temperatures is rather possible, if the paramagnetic particle systems reside far from thermal equilibrium, i.e., at small values of kappa. The application of the theory to the space plasma at the outer boundaries of our heliosphere, the inner heliosheath, leads to an estimation of the ion magnetic moment for this space plasma, that is, μ ≈ 138+/-7 \\text{eV/nT} .

    2014-07-01

    The Reno Orthopaedic Center (ROC) Trauma Fellowship business curriculum is designed to provide the fellow with a graduate level business practicum and research experience. The time commitments in a typical 12-month trauma fellowship are significant, rendering a traditional didactic master's in business administration difficult to complete during this short time. An organized, structured, practical business education can provide the trauma leaders of tomorrow with the knowledge and experience required to effectively navigate the convoluted and constantly changing healthcare system. The underlying principle throughout the curriculum is to provide the fellow with the practical knowledge to participate in cost-efficient improvements in healthcare delivery. Through the ROC Trauma Fellowship business curriculum, the fellow will learn that delivering healthcare in a manner that provides better outcomes for equal or lower costs is not only possible but a professional and ethical responsibility. However, instilling these values without providing actionable knowledge and programs would be insufficient and ineffective. For this reason, the core of the curriculum is based on individual teaching sessions with a wide array of hospital and private practice administrators. In addition, each section is equipped with a suggested reading list to maximize the learning experience. Upon completion of the curriculum, the fellow should be able to: (1) Participate in strategic planning at both the hospital and practice level based on analysis of financial and clinical data, (2) Understand the function of healthcare systems at both a macro and micro level, (3) Possess the knowledge and skills to be strong leaders and effective communicators in the business lexicon of healthcare, (4) Be a partner and innovator in the improvement of the delivery of orthopaedic services, (5) Combine scientific and strategic viewpoints to provide an evidence-based strategy for improving quality of care in a

    2010-04-01

    Dr. Dale Frail, an astronomer at the National Radio Astronomy Observatory (NRAO) in Socorro, New Mexico, has been awarded a prestigious Guggenheim Fellowship, according to the John Simon Guggenheim Memorial Foundation. The Guggenheim Foundation describes its fellowships as "mid-career" awards "intended for men and women who have already demonstrated exceptional capacity for productive scholarship or exceptional creative ability in the arts." Frail, 48, has worked at the NRAO for more than 20 years, first as a postdoctoral fellow, and then as a staff scientist. He received his bachelor's degree in physics from Acadia University in Nova Scotia, and his Ph.D in astronomy from the University of Toronto. Frail is best known for his landmark contributions to the understanding of gamma ray bursts, making critical measurements that provided key insights into the mechanisms of these superenergetic and once-mysterious explosions. He also has made important contributions to the understanding of other astronomical phenomena, including pulsars and their neighborhoods, supernova remnants, and magnetars. In 1992, he was the co-discoverer, with Alex Wolszczan, of the first planets outside our own solar system. "We congratulate Dale on this well-deserved honor that recognizes not only his past achievements but also his potential for exciting scientific work in the future," said Dr. Fred K.Y. Lo, NRAO Director. "We're very proud to see one of our scientists receive such a great honor," Lo added. Frail is one of 180 recipients of this year's Guggenheim Fellowships, chosen from some 3,000 applicants. The fellowships were established in 1925 and past recipients include photographer Ansel Adams, author Saul Bellow, former Secretary of State Henry Kissinger, and chemist Linus Pauling. 102 Guggenheim Fellows have subsequently won Nobel Prizes, and others have received Pulitzer Prizes and other honors. As a Guggenheim Fellow, Frail intends to intensify his research in the areas of pulsars

    Pediatric Hospital Medicine (PHM) is an emerging field in pediatrics and one that has experienced immense growth and maturation in a short period of time. Evolution and rapid expansion of the field invigorated the goal of standardizing PHM fellowship curricula, which naturally aligned with the field's evolving pursuit of a defined identity and consideration of certification options. The national group of PHM fellowship program directors sought to establish curricular standards that would more accurately reflect the competencies needed to practice pediatric hospital medicine and meet future board certification needs. In this manuscript, we describe the method by which we reached consensus on a 2-year curricular framework for PHM fellowship programs, detail the current model for this framework, and provide examples of how this curricular framework may be applied to meet the needs of a variety of fellows and fellowship programs. The 2-year PHM fellowship curricular framework was developed over a number of years through an iterative process and with the input of PHM fellowship program directors (PDs), PHM fellowship graduates, PHM leaders, pediatric hospitalists practicing in a variety of clinical settings, and other educators outside the field. We have developed a curricular framework for PHM Fellowships that consists of 8 education units (defined as 4 weeks each) in 3 areas: clinical care, systems and scholarship, and individualized curriculum.

    The International Atomic Energy Agency (IAEA) Fellowship Program began in April 1958 as a part of the Agency`s Technical Cooperation (TC) Program. Through the TC Program, the IAEA provides technical assistance to meet the needs of recipient countries and to bring about a substantial transfer of technology. This is done by providing experts, equipment, fellowships, and training courses. This report addresses the US component of the fellowship program. These fellowships provide opportunities for research and training of scientists, engineers and physicians from developing countries in the peaceful application of nuclear energy. The fellowships are awarded to persons who are, or soon will be, trusted with responsibilities that are important to the development of their countries. Fellowship awards are classified into two groups, those financed by the IAEA General Fund or the UNDP Fund (Type 1 Fellowships and Scientific Visits), and those offered by Member States (Type 2 Fellowships). In placing individuals, preference is given to applicants from countries that are signatories to the Treaty on Non-Proliferation of Nuclear Weapons or to the Treaty for the Prohibition of Nuclear Weapons in Latin America.

    The International Atomic Energy Agency (IAEA) Fellowship Program began in April 1958 as a part of the Agency`s Technical Cooperation (TC) Program. Through the TC Program, the IAEA provides technical assistance to meet the needs of recipient countries and to bring about a substantial transfer of technology. This is done by providing experts, equipment, fellowships, and training courses. This report addresses the US component of the fellowship program. These fellowships provide opportunities for research and training of scientists, engineers and physicians from developing countries in the peaceful application of nuclear energy. The fellowships are awarded to persons who are, or soon will be, trusted with responsibilities that are important to the development of their countries. Fellowship awards are classified into two groups, those financed by the IAEA General Fund or the UNDP Fund (Type 1 Fellowships and Scientific Visits), and those offered by Member States (Type 2 Fellowships). In placing individuals, preference is given to applicants from countries that are signatories to the Treaty on Non-Proliferation of Nuclear Weapons or to the Treaty for the Prohibition of Nuclear Weapons in Latin America.

    Marie Curie Cancer Care established its nursing service in 1958; however, the service has had little formal evaluation. This study aimed to describe and evaluate the care provided by Marie Curie nurse, and in particular to determine whether patients in their care remained and died at home. Two existing data sets were used: data on all patients referred to the Marie Curie Nursing Services in 147 areas of England, Wales, Scotland and Northern Ireland for 26 months, and data on cancer death registrations in England. A request for a Marie Curie nurse was made for 26,632 patients, 97% of whom had cancer and 11% of whom lived alone. The amount of care provided varied enormously (Marie Curie nurses facilitated home death for many patients. Services need to ensure that mechanisms are in place to achieve data collection. Rigorous prospective evaluation is needed in the future.

    No prior studies have evaluated whether residents who pursue fellowship training achieve higher performance on the Otolaryngology Training Examination (OTE) and whether a specific fellowship will demonstrate a correlation with the corresponding specialty-specific OTE score. To determine whether residents pursuing fellowship training achieve higher performance on the OTE and whether fellowship choice is correlated with higher scores on the related subspecialty section of the OTE. This retrospective analysis included 35 residents training in an academic otolaryngology residency program from July 1, 2003, to June 30, 2014. The OTE scores for postgraduate years 2 through 5 and the type of fellowship were collected for all residents meeting inclusion criteria. Data were collected from September 1 to October 15, 2014, and analyzed from October 16 to December 1, 2014. Residents were divided by whether they pursued fellowship training and by the type of fellowship chosen. Outcome measures included comparison of scores between residents who pursued vs those who did not pursue fellowship training and comparison of subspecialty OTE scores between residents who pursued the corresponding fellowship and those who did not. Of the 35 residents who met the inclusion criteria (24 men and 11 women), 17 (49%) pursued fellowship training. The 3 most common fellowship choices were facial plastic and reconstructive surgery, pediatric otolaryngology, and rhinology (4 residents each [24%]). For all residents, mean scores on the OTE improved each subsequent training year, but this difference was only significant between postgraduate years 2 and 3 (from 60.9% to 68.6% correct; P otolaryngology, 72.9% vs 71.3% [P = .79]; and for rhinology, 72.2% vs 71.2% [P = .91]). Residents who pursued fellowship training did not achieve higher scores on the OTE in any examination year compared with residents who did not pursue fellowship training and did not achieve higher scores within the OTE

  15. The mysterious malleability of titanomagnetite Curie temperatures: An update

    2015-12-01

    Intermediate-composition titanomagnetites (TM30-TM50) have recently been shown to have Curie temperatures (Tc) that depend not only on composition but also quite strongly on thermal history, with increases of 100°C or more in Tc produced by moderate-temperature (300-400° C) annealing in the lab or in slow natural cooling, and equally large decreases produced by more rapid cooling ("quenching") from higher temperatures [e.g., Bowles et al 2013, Nature Communications]. The phenomenon is robustly defined and repeatable, but the underlying mechanism remains enigmatic, although it presumably involves some rearrangement of metal cations within the spinel lattice. New high-and low-temperature measurements, including hysteresis, frequency-dependent AC susceptibility (k(f,T)) and Mössbauer spectroscopy, were carried out to help shed light on the nanoscale mechanisms responsible for the observed changes in Tc. Fabian et al [2015, GJI] have shown for ferrimagnetic compositions in the hematite-ilmenite system that high-T hysteresis measurements exhibit a peak in high-field slope at the Curie temperature, and that the magnitude (area) of this peak is a strong function of cation ordering degree. Our data for synthetic titanomagnetites in quenched and annealed states show some indications of this, although the relationship is not perfectly systematic. On the other hand, our new low-T Mössbauer spectra, measured in the quenched and annealed states, are indistinguishable and argue against any change in site occupancy. Church et al [2011, G3] have proposed that the sharp change in low-T magnetic behavior of intermediate titanomagnetites is a "pinning transition" due to redistribution and localization of ferrous ions within the octahedral sites. Our new k(f,T) results show that the pinning transition in some samples is strongly affected by prior annealing or quenching, suggesting that these treatments affect the intrasite cation distributions. Such an idea is consistent with

    Full Text Available The dependence of perpendicular magnetization and Curie temperature (Tc of Pt/Co/Pt thin films on the thicknesses of Pt seed (Pts and presence of Ta buffer layer has been investigated in this work. Pt and Co thicknesses were varied between 2 to 8 nm and 0.35 to 1.31 nm (across the spin reorientation transition thickness respectively and the Tc was measured using SQUID magnetometer. We have observed a systematic dependence of Tc on the thickness of Pts. For 8nm thickness of Pts the Co layer of 0.35nm showed ferromagnetism with perpendicular anisotropy at room temperature. As the thickness of the Pts was decreased to 2nm, the Tc went down below 250K. XRD data indicated polycrystalline growth of Pts on SiO2. On the contrary Ta buffer layer promoted the growth of Pt(111. As a consequence Ta(5nm/Pt(3nm/Co(0.35nm/Pt(2nm had much higher Tc (above 300K with perpendicular anisotropy when compared to the same stack without the Ta layer. Thus we could tune the ferromagnetic Tc and anisotropy by varying the Pts thickness and also by introducing Ta buffer layer. We attribute these observations to the micro-structural evolution of Pts layer which hosts the Co layer.

    The Scoliosis Research Society traveling fellowship was conceptualized in 1970, repeated in 1972, and, after a pause, restarted in 1993. International traveling fellows visiting North America first commenced in 2000 and have since alternated annually with the North American fellows. Although a senior fellow had always traveled with them, in 2012 the first senior international fellow traveled with the group. This year, the senior fellow was Daniel Chopin from the Neuro-Orthopedic Spine Unit, Lille University Hospital, France, and past Director of the Spine Center, Institut Calot Berck sur Mer (succeeding Dr. Cotrel). The junior fellows were Meric Enercan from the Florence Nightingale Hospital, Istanbul Spine Center, Turkey; J. Naresh-Babu from Mallika Spine Centre, Guntur, Andhra Pradesh, India; and Nasir A. Quraishi from the Centre for Spine Studies and Surgery, Queen's Medical Centre, Nottingham, UK. The host centers were initially suggested by Dr. Chopin, the senior fellow; after some minor tweaking and extensive planning from the Scoliosis Research Society office, the itinerary was confirmed. The researchers were to visit 7 centers in just over 3 weeks. All of the international fellows were going to have an extraordinary adventure although they had not met each other previously. As it turned out, the trip was indeed sensational-professionally stimulating and socially endearing. The following is a short report on this unforgettable experience.

  18. Curie depth vs. flat subduction in Central Mexico

    Science.gov (United States)

    Manea, Marina; Constantin Manea, Vlad

    2010-05-01

    Forearcs located above active subduction zones are generally characterized by low heat flow values, and this is considered a consequence of the subduction of cold slabs beneath continental plates. In the case of Central Mexico, the geometry of the subducting Cocos plate is quite unusual, the slab runs flat for several hundreds of kilometers before plunging into the asthenosphere. This particular geometry has a strong influence on the temperature distribution of the overriding plate where very low heatflow values are recorded (15-30 mW/m2). In this paper we use the aeromagnetic map of Mexico in order to infer the maximum depth of magnetic source, regarded as Curie depth and corresponding to a temperature of 575-600C°. Our spectral analysis revealed the existence of a deep magnetic source (30-40 km). We compare these results with the thermal structure associated with flat slab subduction in the area. We obtained a good agreement between the two estimates and we conclude that flat slab subduction in Central Mexico controls the maximum depth of magnetic sources in the overriding plate.

    The breadth of family medicine (FM) generates debate about the length of residency training. One argument used by proponents for lengthening training is that residents feel unprepared for practice. The objectives of our study were to (1) identify the proportion of FM residency graduates intending to pursue fellowship training and those who would have done an additional year of core residency training had it been available, and (2) determine whether an association exists between these two variables. We used data collected by the American Board of Family Medicine (ABFM) as part of resident certification examination application in 2014 and 2015. Data included fellowship intention, and interest in pursuing another year of residency training if it were available. We used descriptive and bivariate statistics. The questionnaire was completed by 6,235 residents, of which 17.0% (n=1,063) intended to enroll in a fellowship. Overall 54.2% of residents were "not at all likely" to extend residency training, with 19.9% "extremely/moderately likely". Forty-six percent of those intending a fellowship were "not at all likely" to extend training and only 29% of those "extremely/moderately likely" to extend residency training intended to enroll in a fellowship. We found a disconnect between fellowship intention and desire for another year of residency training. Desire for fellowship may be more about obtaining specific skills and expertise or additional certifications, and less about being prepared for general practice in family medicine.

  20. Can a resident's publication record predict fellowship publications?

    Directory of Open Access Journals (Sweden)

    Vinay Prasad

    Full Text Available BACKGROUND: Internal medicine fellowship programs have an incentive to select fellows who will ultimately publish. Whether an applicant's publication record predicts long term publishing remains unknown. METHODS: Using records of fellowship bound internal medicine residents, we analyzed whether publications at time of fellowship application predict publications more than 3 years (2 years into fellowship and up to 7 years after fellowship match. We calculate the sensitivity, specificity, positive and negative predictive values and likelihood ratios for every cutoff number of application publications, and plot a receiver operator characteristic curve of this test. RESULTS: Of 307 fellowship bound residents, 126 (41% published at least one article 3 to 7 years after matching, and 181 (59% of residents do not publish in this time period. The area under the receiver operator characteristic curve is 0.59. No cutoff value for application publications possessed adequate test characteristics. CONCLUSION: The number of publications an applicant has at time of fellowship application is a poor predictor of who publishes in the long term. These findings do not validate the practice of using application publications as a tool for selecting fellows.

    The theory of "threshold concepts" argues that within every discipline there is knowledge that transforms understanding and leads to a previously inaccessible way of thinking, without which the learner cannot progress. This study investigates the factors influencing the development of the characteristic ways of thinking and practicing as a microsurgeon during a microsurgical fellowship. We analyze the challenges in the development of these characteristics during focused fellowship training in microsurgery, of which some could potentially represent "threshold concepts." A qualitative research methodology was followed. Semistructured interviews with trainers and trainees from microsurgical units in the United Kingdom (UK) and the United States (US) were conducted. Data were analyzed using the Dedoose (Manhattan Beach, CA) qualitative data analysis software and interpreted using the theory of "threshold concepts." Five trainees and four trainers from the UK and the US participated in this research project. Although initially some trainees had particular difficulty in developing their practical microsurgical skills, this improved rapidly with adequate practice. Cognitive skills and especially the ability to expect the unexpected and the ability recognize complications presented as a significant challenge for trainees and transformed their understandings regarding the qualities of a microsurgeon. Microsurgical fellowship curricula can be redesigned using the theory of threshold concepts, creating a dynamic framework that addresses individual trainee needs to develop the practical and cognitive skills necessary for independent practice of microsurgery.

    The c- and a-axis linear thermal expansivities of high purity single crystals of gadolinium were measured in the temperature range 270/sup 0/K to 320/sup 0/K. Length changes were translated to capacitance changes with a modified normal geometry 3-terminal capacitance dilatometer. An ac 3-terminal capacitance bridge was employed to measure nominal 10 pF capacitances to a precision of 10/sup -7/ pF, which corresponds to a relative length change sensitivity of 10/sup -10/. A 25 ohm platinum resistance thermometer was used to detect the dilatometer temperature to a precision of 10 ..mu..K with an ac resistance bridge. The c-axis expansivity was negative and had a large (approximately equal to 10/sup -4/ K/sup -1/) peak at 293.435/sup 0/K, while the a-axis expansivity was positive and had a smaller (approximately equal to 10/sup -5/ K/sup -1/) peak at 293.363/sup 0/K. The values of the Curie temperatures (T/sub c/'s) and critical point exponents for the c- and a-axis crystals were obtained from fitting power law equations to the expansivities.

    To investigate expectations, logistics, and costs relevant to the hand surgery fellowship application process. We sought to discover (1) what both applicants and program directors are seeking, (2) what both parties have to offer, (3) how both parties collect information about each other, and (4) the costs incurred in arranging each match. We conducted on-line surveys of hand surgery fellowship applicants for appointment in 2015 and of current fellowship program directors. Sixty-two applicants and 41 program directors completed the survey. Results revealed applicants' demographic characteristics, qualifications, method of ranking hand fellowship programs, costs incurred (both monetary and opportunity) during the application process, ultimate match status, and suggestions for change. Results also revealed program directors' program demographics, rationale for offering interviews and favorably ranking applicants, application-related logistical details, costs incurred (both monetary and opportunity) during the application process, and suggestions for change. Applicants for hand surgery fellowship training are primarily interested in a potential program's academic reputation, emphasis on orthopedic surgery, and location. The typical, successfully matched applicant was a 30-year-old male orthopedic resident with 3 publications to his credit. Applicants rely on peers and Web sites for information about fellowships. Fellowship directors are primarily seeking applicants recommended by other experienced surgeons and with positive personality traits. The typical fellowship director offers a single year of orthopedic-based fellowship training to 2 fellows per year and relies on a common application and in-person interviews to collect information about applicants. Applicants appear to be more concerned than directors about the current state of the match process. Applicants and directors alike incur heavy costs, in both dollars and opportunity, to arrange each match. A nuanced

  6. Clinical fellowship training in pathology informatics: A program description

    Directory of Open Access Journals (Sweden)

    John R Gilbertson

    2012-01-01

    Full Text Available Background: In 2007, our healthcare system established a clinical fellowship program in pathology informatics. In 2011, the program benchmarked its structure and operations against a 2009 white paper "Program requirements for fellowship education in the subspecialty of clinical informatics," endorsed by the Board of the American Medical Informatics Association (AMIA that described a proposal for a general clinical informatics fellowship program. Methods: A group of program faculty members and fellows compared each of the proposed requirements in the white paper with the fellowship program′s written charter and operations. The majority of white paper proposals aligned closely with the rules and activities in our program and comparison was straightforward. In some proposals, however, differences in terminology, approach, and philosophy made comparison less direct, and in those cases, the thinking of the group was recorded. After the initial evaluation, the remainder of the faculty reviewed the results and any disagreements were resolved. Results: The most important finding of the study was how closely the white paper proposals for a general clinical informatics fellowship program aligned with the reality of our existing pathology informatics fellowship. The program charter and operations of the program were judged to be concordant with the great majority of specific white paper proposals. However, there were some areas of discrepancy and the reasons for the discrepancies are discussed in the manuscript. Conclusions: After the comparison, we conclude that the existing pathology informatics fellowship could easily meet all substantive proposals put forth in the 2009 clinical informatics program requirements white paper. There was also agreement on a number of philosophical issues, such as the advantages of multiple fellows, the need for core knowledge and skill sets, and the need to maintain clinical skills during informatics training.

    The convergence between the Indian and Eurasian plates has developed the world's extreme topography and has also resulted in the occurrence of large earthquakes in the region. The April 25, 2015 (Mw 7.8) earthquake in central Nepal is the largest earthquake that has been recorded in the Nepal Himalaya since 1934. The earthquake caused thousands of people to die and massive destruction of famous heritage-structures in and around kathmandu and was attributed to the interations between the Indian and Eurasian plates. The crustal thermal structure which can be inferred from the Curie-point depths is critial to understand the seismotectonics and subduction in the Indian-Himalayan region. We present our inversion of Curie-point depths of the Indian-Himalayan region based on fractal spectral analyses both from aeromagnetic and satellite data. The first magnetic anomaly model used for estimatiion of Curie-point depths is the EMAG2 model, which has a resolution of 2-arc minute and an altitude of 4 km above the geoid. The second magnetic anomaly model is the CHAMP lithospheric model MF6. The third and the last magnetic anomaly model is the NGDC-720 lithospheric model, which is based on both the EMAG2 and MF6 models, has the smallest wavelength of 56 km. We first test variable windows sizes of 100.8×100.8 km2, 201.6×201.6 km2 and 302.4×302.4 km2 to estimate the Curie-point depths and then take the average of the results from these three different window sizes as the final Curie depths for the EMAG2 and MF6 models, respectively. The differences between the two Curie depths estimations from the EMAG2 and MF6 models mostly range within about ±4 km except for that in the Central Tibetan Plateau and Northeast India. This result shows that the NGDC-720 lithospheric model which contains both the EMAG2 and MF6 models is valid for the Curie-point estimation in the Indian-Himalayan region. The average Curie depths estimated from the NGDC-720 lithospheric model show small values in

    The effect of Gd doping and O deficiency on the electronic structure, exchange interaction, and Curie temperature of EuO in the cubic and tetragonal phases is studied by means of density functional theory. For both defects, the Curie temperature is found to exhibit a distinct maximum as a function of the defect concentration. The existence of optimal defect concentrations is explained by the interplay of the on-site, RKKY, and superexchange contributions to the magnetism.

    In 2007, our healthcare system established a clinical fellowship program in Pathology Informatics. In 2010 a core didactic course was implemented to supplement the fellowship research and operational rotations. In 2011, the course was enhanced by a formal, structured core curriculum and reading list. We present and discuss our rationale and development process for the Core Curriculum and the role it plays in our Pathology Informatics Fellowship Training Program. The Core Curriculum for Pathology Informatics was developed, and is maintained, through the combined efforts of our Pathology Informatics Fellows and Faculty. The curriculum was created with a three-tiered structure, consisting of divisions, topics, and subtopics. Primary (required) and suggested readings were selected for each subtopic in the curriculum and incorporated into a curated reading list, which is reviewed and maintained on a regular basis. Our Core Curriculum is composed of four major divisions, 22 topics, and 92 subtopics that cover the wide breadth of Pathology Informatics. The four major divisions include: (1) Information Fundamentals, (2) Information Systems, (3) Workflow and Process, and (4) Governance and Management. A detailed, comprehensive reading list for the curriculum is presented in the Appendix to the manuscript and contains 570 total readings (current as of March 2012). The adoption of a formal, core curriculum in a Pathology Informatics fellowship has significant impacts on both fellowship training and the general field of Pathology Informatics itself. For a fellowship, a core curriculum defines a basic, common scope of knowledge that the fellowship expects all of its graduates will know, while at the same time enhancing and broadening the traditional fellowship experience of research and operational rotations. For the field of Pathology Informatics itself, a core curriculum defines to the outside world, including departments, companies, and health systems considering hiring a

    As the macro behavior of the strength of exchange interaction, state of the art of Curie temperature Tc, which is directly proportional to the exchange integrals, makes sense to the high-frequency and high-reliability microwave devices. Challenge remains as finding a quantitative way to reveal the relationship between the Curie temperature and the exchange integrals for doped barium hexaferrites. Here in this report, for La-substituted barium hexaferrites, the electronic structure has been determined by the density functional theory (DFT) and generalized gradient approximation (GGA). By means of the comparison between the ground and relative state, thirteen exchange integrals have been calculated as a function of the effective value Ueff. Furthermore, based on the Heisenberg model, the molecular field approximation (MFA) and random phase approximation (RPA), which provide an upper and lower bound of the Curie temperature Tc, have been adopted to deduce the Curie temperature Tc. In addition, the Curie temperature Tc derived from the MFA are coincided well with the experimental data. Finally, the strength of superexchange interaction mainly depends on 2b-4f1, 4f2-12k, 2a-4f1, and 4f1-12k interactions.

    The Arabian shield is a Precambrian complex of igneous and metamorphic rocks located approximately one-third of the way across the western Arabian Peninsula, with uncommon exposures along the Red Sea coast. We used aeromagnetic data acquired by others over the past several decades to estimate the depth to the Curie temperature isotherm throughout this region. Our goal was to further understand the lithospheric structure, thermal activity, and seismicity to assist in geothermal exploration. We also compared the Curie temperature isotherm with the crustal thickness to investigate the possibility that mantle rocks are magnetic in some parts of the Arabian shield. Depths to the Curie isotherm were estimated by dividing the regional aeromagnetic grid into 26 overlapping windows. Each window was then used to estimate the shape of the power spectrum. The windows had dimensions of 250 × 250 km to allow investigation of depths as deep as 50 km. The results show the presence of a Curie isotherm at a depth of 10-20 km near the Red Sea, increasing to 35-45 km in the interior of the Arabian shield. The Curie isotherm generally lies above the Moho in this region but deepens into the mantle in some locations, notably beneath the Asir Terrane.

    The American Orthopaedic Association-Japanese Orthopaedic Association (AOA-JOA) Traveling Fellowship, which began in 1992 as a collaborative effort between the 2 orthopaedic communities, is aimed at fostering leadership among early-career surgeons through clinical, academic, and cultural exchange. Over 3 weeks, we experienced an extraordinary journey that led us across nearly 800 miles of the picturesque Japanese countryside, with stops at 6 distinguished academic centers. The opportunity to become personally acquainted with orthopaedic leaders in Japan, learn from their experiences, and immerse ourselves in the ancient and storied culture of a beautiful country was one that we will not soon forget. Along the way, we accumulated a wealth of information while enjoying the legendary hospitality of the Japanese people. There is a ubiquitous challenge in delivering cost-effective, accessible health care while maintaining a commitment to education and research. The U.S. orthopaedic community may take solace in the fact that our Japanese colleagues stand with us as partners in this pursuit, and our relationship with them continues to grow stronger through endeavors such as the AOA-JOA Traveling Fellowship. We look forward to honoring our Japanese colleagues in 2017 when we host them in the United States.

  3. Variations in Moho and Curie depths and heat flow in Eastern and Southeastern Asia

    Li, Chun-Feng; Wang, Jian

    2016-03-01

    The Eastern and Southeastern Asian regions witness the strongest land-ocean and lithosphere-asthenosphere interactions. The extreme diversity of geological features warrants a unified study for a better understanding of their geodynamic uniqueness and/or ubiquity from a regional perspective. In this paper we have explored a large coverage of potential field data and have detected high resolution Moho and Curie depths in the aforementioned regions. The oldest continental and oceanic domains, i.e. the North China craton and the Pacific and Indian Ocean have been found thermally perturbed by events probably linked to small-scale convection or serpentinization in the mantle and to numerous volcanic seamounts and ridges. The thermal perturbation has also been observed in proximity of the fossil ridge of the western Philippine Sea Basin, which shows anomalously small Curie depths. The western Pacific marginal seas have the lowest Moho temperature, with Curie depths generally larger than Moho depths. The contrary is true in most parts of easternmost Eurasian continent. Magmatic processes feeding the Permian Emeishan large igneous province could have also been genetically linked to deep mantle/crustal processes beneath the Sichuan Basin. The regionally elongated magnetic features and small Curie depths along the Triassic Yangtze-Indochina plate boundary suggest that the igneous province could be caused by tectonic processes along plate margins, rather than by a deep mantle plume. At the same time, we interpret the Caroline Ridge, the boundary between the Pacific and the Caroline Sea, as a structure having a continental origin, rather than as hotspot or arc volcanism. The surface heat flow is primarily modulated by a deep isotherm through thermal conduction. This concordance is emphasized along many subduction trenches, where zones of large Curie depths often correspond with low heat flow. Local or regional surface heat flow variations cannot be faithfully used in inferring

    The guidelines for health economics and outcomes research (HEOR) fellowship training programs devised by the American College of Clinical Pharmacy (ACCP) and the International Society of Pharmacoeconomics and Outcomes Research (ISPOR) suggest that continuous improvements are made to ensure that postgraduate training through didactic and professional experiences prepare fellows for HEOR research careers. The HEOR Fellowship Program at Novartis Pharmaceuticals Corporation was standardized to enhance the fellows' HEOR research understanding and align professional skill sets with the ACCP-ISPOR Fellowship Program Guidelines. Based on feedback from an internal task force comprised of HEOR employees and current and former fellows, the HEOR Fellowship Program was normatively and qualitatively assessed to evaluate the current curricular program. Fellowship program activities were instituted to ensure that the suggested minimum level requirements established by the guidelines were being met. Research opportunities enabling fellows to work hand-in-hand with other fellows and HEOR professionals were emphasized. Curricular enhancements in research methodology and professional training and development, and materials for a structured journal club focusing on specific methodological and HEOR research topics were developed. A seminar series (e.g., creating SMART Goals, StrengthsFinder 2.0) and professional courses (e.g., ISPOR short courses, statistics.com) were included to enhance the fellows' short- and long-term professional experience. Additional program attributes include an online reference library developed to enrich the current research facilities and a Statistical Analysis Software training program. Continuously assessing and updating HEOR fellowship programs keeps programs up-to-date in the latest HEOR concepts and approaches used to evaluate health care, both professionally and educationally.

    Mechanical spectroscopy measurement is performed to study the internal friction of nanocrystalline (NC) nickel with an average grain size of 23 nm from room temperature to 610 K.An internal friction peak is observed at about 550 K,which corresponds to the Curie transition process of the NC nickel according to the result of magnetization test.Moreover,the fact that the Curie temperature of NC nickel is lower than that of coarse-grained nickel is explained by an analytical model based on the weakening of cohesive energy.

    The magnetic properties of dilute magnetic semiconductors (DMS) are calculated by using the local density approximation +U(LDA+U) method. In the LDA+U, occupied d-states in (Ga, Mn)As are predicted at lower energy than in the LDA and p-d exchange interaction explains calculated concentration dependence of Curie temperature very well. In (Ga, Mn)N, unoccupied d states are predicted at higher energy by LDA+U, resulting in higher Curie temperatures than in LDA at high concentrations due to the suppression of the anti-ferromagnetic super-exchange interaction.

    Marques Tavares was awarded a fellowship for his proposal “The ttbar asymmetry and beyond” to starting in September 2012. This is the final report summarizing the research activities and accomplishments achieved with this grant support. With support from the DOE graduate fellowship Marques Tavares, Katz and Xu at BU have investigated a new technique for obtaining quantitative results in strongly coupled field theories with broken conformal invariance. Such theories are especially interesting as they may be candidates for physics beyond the standard model with possible applications to strongly coupled electroweak symmetry breaking. However, because of the strong coupling even qualitative results about the spectrum of such theories are not rigorously understood.

    Currently, very little information is known regarding the research education of pediatric anesthesia fellows. The main objective of the current investigation was to evaluate the status of research training in pediatric anesthesia fellowship programs in the United States. Survey responses were solicited from forty-six pediatric anesthesia fellowship directors. Questions evaluated department demographic information, the extent of faculty research activity, research resources and research funding in the department, the characteristics of fellow research education and fellow research productivity, departmental support for fellow research, and perceived barriers to fellow research education. Thirty-six of forty-six fellowship directors responded to the survey, for a response rate of 78%. Eight of fourteen (57%) programs with a structured curriculum had more than 20% of graduating fellows publish a peer-reviewed manuscript compared with only five of twenty-two (23%) programs, which did not have a structured research curriculum (P = 0.03). While the majority of program directors (thirty of thirty-six (83%)) did not think that fellows are adequately trained to pursue research activities, only a minority of program directors (7 of 36 (19%)) thought that an extra year of fellowship dedicated to research should become a requirement. Structured research curriculum is associated with increased research productivity during pediatric anesthesia fellowship. Important barriers to fellows' research education include high clinical demands and lack of research time for faculty. Despite acknowledging the poor research education, a small minority of fellowship directors supports the addition of an extra year exclusively dedicated to research. © 2013 John Wiley & Sons Ltd.

    We started this journey excited by the prospects of visiting Japan, a country with a proud and historic past. We ended the fellowship accomplishing those goals, and we left with a great deal of admiration for our orthopaedic colleagues halfway around the world for their excellence in education, clinical care, and research. Their hospitality and attention to the details of our visit were exemplary and a lesson to us as we host visiting fellows in the future. Japan reflects its past, but it also offers a preview into our own nation's future: an aging population, a shrinking workforce, a stagnant economy, nationalized health care, and a mushrooming national debt. Of all of these factors, it is the aging population that we, as orthopaedic surgeons, will be most acutely aware of and involved with. The degenerative disorders that affect elderly patients dominate the landscape of surgical care in Japan. Osteoporosis and osteopenia permeate many aspects of care across orthopaedic subspecialties. The surgeons in Japan are developing innovative and cost-effective means of treating the large volume of older patients within the fiscal constraints of a nationalized health-care system. We learned, and will continue to learn more, from Japan about the management of this growing patient population with its unique pathologies and challenges. With the recent natural disaster and ongoing safety concerns in Japan, the character and will of the people of Japan have been on display. Their courage and resolve combined with order and compassion are a testament to the nation's cultural identity. The seeds of the Traveling Fellowship were planted shortly after Japan's last wide-scale reconstruction, and the ties that have bound the JOA and the AOA together are strengthened through this trying time. We strongly urge our colleagues in the U.S. to help support the people, the physicians, and the health-care system of Japan through its most recent tribulations and offer them the same care and

    2014-11-01

    Overall resident interest in certain subspecialties changes with time. We sought to investigate the latest 6-year trend in interventional radiology (IR) and neuroradiology fellowship applications and how it has affected competitiveness in obtaining a position. We analyzed statistics published by the National Resident Matching Program in Results and Data: Specialties Matching Service from 2008 to 2013. From these data, we calculated the positions per IR applicant (PPIRA) and positions per neuroradiology applicant (PPNRA) for each year. The number of positions per applicant is one way to assess specialty competitiveness on a supply-and-demand basis. A lower PPIRA or PPNRA indicates a more competitive year. PPIRA has decreased every year, from 1.71 to the present 0.84, and contributed to 52 applicants being unmatched in 2013, up from 9 in 2008. Accordingly, the number of unfilled positions has decreased from 86 in 2008 to 8 in 2013. PPNRA waxed and waned from 2008 to 2010 but stabilized at around 1.15 thereafter. The number of unfilled positions has never dropped below 46. The number of unmatched applicants was consistently in the teens, except in 2011, when it increased to 23. Interest in IR fellowship has increased significantly over the past 6 years, whereas interest in neuroradiology fellowships has plateaued. IR fellowships have become increasingly competitive, leading to many unmatched residents. Copyright © 2014 American College of Radiology. Published by Elsevier Inc. All rights reserved.

    Recent years have seen significant growth in palliative medicine training programs and positions. There are plans to pursue palliative medicine specialty status with the American Board of Medical Specialties and accreditation of fellowship programs with the American College of Graduate Medical Education. A work group of program directors, supported initially by the Cleveland Clinic and then by the American Board of Hospice and Palliative Medicine, has recently published standards for fellowship training. Despite this, fundamental questions remain about defining the field and delineating the knowledge and skills expected following completion of specialty training. In this article, we describe the first fellowship program in palliative medicine (PMP) in the United States, developed and supported by the Cleveland Clinic Foundation. The program has been implemented as part of the Harry R. Horvitz Center for Palliative Medicine, founded in 1987 as the first comprehensive integrated US program in this field. This training program, in existence since 1989, features a traditional rotational structure with an inpatient primary care service, inpatient consult services, and an outpatient consult/hospice service. This article outlines the syllabus developed for this fellowship, given what we believe to be the essential knowledge base for the field of palliative medicine.

    Assessment of scholarly productivity as measured by research output is a key component of decisions regarding appointment and advancement in academic otolaryngology. An increasing number of graduating residents are pursuing postresidency fellowships, and evaluation of research productivity among these subspecialists is important in determining their role in academic otolaryngology departments. The h-index is a reliable indicator of research productivity, as it takes into account both quantity and relevance of research contributions. Our objective was to evaluate and compare trends in research productivity among the various otolaryngology subspecialties. Analysis of research productivity trends among otolaryngology subspecialties using the h-index. Faculty members from 92 academic otolaryngology departments were organized by subspecialty and academic rank, and their research productivity, as measured by the h-index, was calculated using the Scopus database. Fellowship-trained otolaryngologists in academic programs had higher h-indices than non-fellowship-trained otolaryngologists. Head and neck surgeons and otologists had significantly higher research productivity than their peers in other otolaryngology subspecialties. Analysis of the subspecialties of chairpersons indicated that 62% were either head and neck surgeons or otologists. Fellowship-trained otolaryngologists had higher h-indices, and faculty members trained in the subspecialties with the highest research productivity were disproportionately represented in positions of leadership within academic otolaryngology, probably reflecting the importance of research contributions in the academic advancement process, although other factors, such as educational contributions and clinical performance, may also be important factors.

    To evaluate the financial impact of pursuing a fellowship in otolaryngology. Retrospective financial analysis using American Academy of Otolaryngology-Head and Neck Surgery survey data. The American Academy of Otolaryngology-Head and Neck Surgery report, entitled Socioeconomic Study among Members April 2011, gives a financial profile of respondents who reported their primary area of specialization as either general otolaryngology or a specific area of subspecialization. Weighted averages were calculated from the reported data. The weighted averages were used to calculate a net present value (NPV) over a 30-year contiguous career. The NPV for general otolaryngology was $4.73 million. The NPV for the following subspecialties in relation to general otolaryngology were (in hundred thousands) as follows: otolaryngologic allergy (-$1153), sleep medicine (-$677), otology/neurotology (-$339), laryngology (-$288), head and neck (-$191), pediatric otolaryngology (-$176), facial plastic surgery (-$139), skull base surgery ($122), rhinology ($285), and allergy and immunology ($350). Ninety-four percent of general otolaryngology respondents were in private practice. Most subspecialists worked in an academic setting. Fellowship training in otolaryngology will affect career earnings of prospective fellows. The overall financial impact of fellowship training, calculating in the delay in receiving a full clinical salary, should be factored into the decision to pursue fellowship training.

    Interest in pediatric otolaryngology fellowship training is growing. The workforce implications of this growing interest are unclear and understudied. To analyze trends in pediatric otolaryngology training, determine where fellows who graduated over the past 10 years are currently practicing, and test the hypothesis that graduates from Accreditation Council for Graduate Medical Education (ACGME)–accredited programs were more likely to have academic tertiary positions with faculty appointments. We conducted a web-based analysis of pediatric otolaryngology fellowship graduates. The names of all 274 applicants who were matched to pediatric otolaryngology fellowships from May 31, 2003, to May 31, 2014, were obtained from the SF Match website. Accreditation status of each program for each match year was obtained from the ACGME website. We then performed an Internet search for the current practice location of each matched applicant. Analysis was conducted from January 1, 2015, to May 1, 2015. Practice setting per year of fellowship match and accreditation status of program. For the 2003 to the 2014 match years, there was an increase from 5 to 22 accredited pediatric otolaryngology fellowship programs overall; simultaneously, the number of yearly matched applicants increased from 14 to 35. More graduates with ACGME accreditation practice at academic settings compared with graduates without ACGME accreditation although the difference was not statistically significant (67.1% vs. 50.7%; P = .15). Graduates from accredited programs, however, were significantly more likely to practice at a hospital-based setting compared with those from nonaccredited programs (81.7% vs. 65.5%; P = .003). Fellows trained in the last 10 years are relatively well distributed across the country. The number of pediatric otolaryngology fellowship applicants as well as total number of matched applicants and ACGME-accredited positions has risen in the last 10 years. It appears that a higher

  15. Large deviations of the finite-time magnetization of the Curie-Weiss random-field Ising model

    Paga, Pierre; Kühn, Reimer

    2017-08-01

    We study the large deviations of the magnetization at some finite time in the Curie-Weiss random field Ising model with parallel updating. While relaxation dynamics in an infinite-time horizon gives rise to unique dynamical trajectories [specified by initial conditions and governed by first-order dynamics of the form mt +1=f (mt) ] , we observe that the introduction of a finite-time horizon and the specification of terminal conditions can generate a host of metastable solutions obeying second-order dynamics. We show that these solutions are governed by a Newtonian-like dynamics in discrete time which permits solutions in terms of both the first-order relaxation ("forward") dynamics and the backward dynamics mt +1=f-1(mt) . Our approach allows us to classify trajectories for a given final magnetization as stable or metastable according to the value of the rate function associated with them. We find that in analogy to the Freidlin-Wentzell description of the stochastic dynamics of escape from metastable states, the dominant trajectories may switch between the two types (forward and backward) of first-order dynamics. Additionally, we show how to compute rate functions when uncertainty in the quenched disorder is introduced.

    2011-01-01

    Marie Curie, née Maria Sklodowska, was born on November 7, 1867 in Warsaw (Poland). She suffered from leukaemia and died on June 4, 1934. She was buried with full honours at Pantheon. Marie Curie and her husband Pierre Curie discovered the radioactive elements Polonium (84Po210), Thorium (90Th232) and Radium (88Ra226). Marie Curie introduced the term radioactivity into science. She was the first woman who got Ph.D. in France, the first woman professor at Sorbonne, Paris and Medical Academy. Of all the women who have ever won the Nobel Prize, Marie Curie was the only who received it twice. During World War I Marie Curie designed a mobile x-ray room "radiologic car". Marie Curie had an x-ray machine installed into a car and demonstrated how to use its dynamo for electric power production necessary for the x-ray machine to work. She had 20 cars with moving radiological lab made and trained 150 people to work on them. She brought something radically new into military medicine--mobile x-ray diagnostics. With the discovery of radioactive elements a new medical branch, radiotherapy, was developed.

    The purpose of this study is to determine the association between gynecologic oncology fellowship training factors, including fellowship length, and a career in academic medicine. A survey was sent to all 980 gynecologic oncologists identified via the SGO membership directory. The survey questions focused on demographics, fellowship training, practice- type, and research involvement. Demographics of the study population and survey responses were reported using frequencies and percentages. Chi-squared tests were used to test for associations between selected survey responses and length of fellowship. The authors received 410 (42 %) responses. Most respondents (60 %) graduated from a 3-year fellowship, while 27 and 13 % attended 2- and 4-year fellowships, respectively. Practice descriptions included academic/university (52 %), community/private practice (21 %), private practice with academic appointment (20 %), and other (7 %). A majority (64 %) reported current involvement in research as a principal investigator (PI); however, 54 % reported spending 10 % or less of their time in research-related activities. Approximately half reported that their fellowship research experience contributed to their current practice. Graduates of 3- and 4-year fellowships had similar rates of employment in academic/university settings (58 and 52 %, respectively). Graduates of 4-year fellowships were more likely to hold an advanced degree and 11 or more publications at completion of fellowship. A majority of graduates of a gynecologic oncology fellowship practice in an academic/university setting and are involved in research. Fellowship length does not correlate with a current academic medicine appointment. Graduates of 4-year fellowships are more likely to hold additional advanced degrees and more publications.

    2007-07-13

    We consider a magnetic impurity in two different S=1/2 Heisenberg bilayer antiferromagnets at their respective critical interlayer couplings separating Néel and disordered ground states. We calculate the impurity susceptibility using a quantum Monte Carlo method. With intralayer couplings in only one of the layers (Kondo lattice), we observe an anomalous Curie constant C*, as predicted on the basis of field-theoretical work [S. Sachdev, Science 286, 2479 (1999)10.1126/science.286.5449.2479]. The value C* = 0.262 +/- 0.002 is larger than the normal Curie constant C=S(S+1)/3. Our low-temperature results for a symmetric bilayer are consistent with a universal C*.

    The effect of the magnetization fluctuations on the resistivity of GaMnAs near the Curie temperature TC was experimentally studied. It is shown that the determination of TC from the maximum of the temperature derivative of the resistivity is valid for the samples with a high concentration of free carries. Whereas, for the samples with low concentration of free carriers the TC coincides with the resistivity maximum. The magnetic specific heat for T>TC demonstrates the crossover from the one dimensional to the three dimensional critical behavior when the temperature become closer to the Curie temperature. This is explained by the formation of the ferromagnetic phase in the paramagnetic side of the phase transition which is started from Mn-Mn dimers oriented along one direction.

    High Curie temperaturepiezoelectricthin films of xBiInO3-(1-x)PbTiO3 (x = 0.10, 0.15, 0.20, and 0.25) were prepared by pulsed laser deposition. It was found that the tetragonality of films decreased with increasing BI content. The dielectric constant and transverse piezoelectric coefficient (e31,f ) exhibit the highest values of 665 and -13.6 C/m(2) at x = 0.20. Rayleigh analyses were performed to identify the extrinsic contributions to dielectric nonlinearity with different x. The composition with x = 0.20 also exhibits the largest extrinsic contributions to dielectric nonlinearity. The Curie temperature (TC ) is increased with increasing x content from 558 to 633 °C; TC at x = 0.20 is about 584 °C.

    As the most famous woman scientist of the twentieth century, there has been no shortage of books and articles on the life and career of Marie Curie (1867-1934). Her role as director of a laboratory-based research school in the new scientific field of radioactivity, a field which embraced both chemistry and physics, however, has never been examined. In recent years, there has been a growing interest in the question of research schools, and Morrell, Ravetz, Geison, and Klosterman, amongst others, have written on this subject. Using, in part, the methodology of Morrell, this paper investigates the role of Marie Curie as a school director in the Paris Faculty in the years 1907-14, examining the work and characteristics of her school and assessing her effectiveness as a director.

  4. Different tracks for pathology informatics fellowship training: Experiences of and input from trainees in a large multisite fellowship program

    Directory of Open Access Journals (Sweden)

    Bruce P Levy

    2012-01-01

    Full Text Available Background: Pathology Informatics is a new field; a field that is still defining itself even as it begins the formalization, accreditation, and board certification process. At the same time, Pathology itself is changing in a variety of ways that impact informatics, including subspecialization and an increased use of data analysis. In this paper, we examine how these changes impact both the structure of Pathology Informatics fellowship programs and the fellows′ goals within those programs. Materials and Methods: As part of our regular program review process, the fellows evaluated the value and effectiveness of our existing fellowship tracks (Research Informatics, Clinical Two-year Focused Informatics, Clinical One-year Focused Informatics, and Clinical 1 + 1 Subspecialty Pathology and Informatics. They compared their education, informatics background, and anticipated career paths and analyzed them for correlations between those parameters and the fellowship track chosen. All current and past fellows of the program were actively involved with the project. Results: Fellows′ anticipated career paths correlated very well with the specific tracks in the program. A small set of fellows (Clinical - one or two year - Focused Informatics tracks anticipated clinical careers primarily focused in informatics (Director of Informatics. The majority of the fellows, however, anticipated a career practicing in a Pathology subspecialty, using their informatics training to enhance that practice (Clinical 1 + 1 Subspecialty Pathology and Informatics Track. Significantly, all fellows on this track reported they would not have considered a Clinical Two-year Focused Informatics track if it was the only track offered. The Research and the Clinical One-year Focused Informatics tracks each displayed unique value for different situations. Conclusions: It seems a "one size fits all" fellowship structure does not fit the needs of the majority of potential Pathology

    X-ray line broadening is found to be an effective parameter to estimate the strain associated with rare earth ion (Gd3+)-doped polycrystalline bismuth vanadate(Bi2VO5.5). The strain increases with increasing Gd3+ concentration. It is anisotropic and found to be maximum in (111) plane. The Curie temperature which is known to decrease with increase in the rare earth ion concentration in these compounds is correlated with increase in strain.

    Using full-potential local-orbital minimum-basis along with spin-polarized relativistic Korringa-Kohn-Rostoker methods, we study the electronic, Fermi surface, Curie temperature and optical properties of Zr2CoAl alloy. The alloy with Li2AgSb and Cu2MnAl structures are compared in terms of magnetic properties, and the electronic structures in two structures are also discussed. According to the calculated electronic states, it finds that the Zr2CoAl with Li2AgSb structure is half-metallic ferromagnet with an integral magnetic moment of 2.00μB , meanwhile we also notice the d-d and p-d hybridizations are responsible for the formation of minority-spin gap, furthermore, the fat-bands are applied to discuss the mixture between d and p electrons in the vicinity of the Fermi level. The Fermi surfaces related to the valence bands are constructed, and it is found that the spin-up valence bands 26, 27 and 28 across the Fermi energy dominate the nature of electrons. By mapping the system onto a Heisenberg Hamiltonian, we obtain the exchange coupling parameters, and observe that the Zr(A)-Co(C) and Zr(A)-Zr(B) interactions provide a major contribution for exchange interactions. Based on the calculated exchange coupling parameters, the Curie temperature is estimated to be 287.86 K at equilibrium, and also the dependence of Curie temperature on lattice constant related to the tunable Curie temperature in Zr2CoAl alloy is studied. Finally, we report the optical properties of Zr2CoAl alloy, and present the photon energy dependence of the absorption, the optical conductivity and the loss function.

    Sr{sub 2}FeMoO{sub 6} and related double perovskites are nowadays intensely investigated due to their potential in the field of spintronics. It has been previously shown that the Curie temperature (T {sub C}) of double perovskites can be increased by injecting carriers in the conduction band. We report here on an alternative approach to reinforce the magnetic interaction, and thus raise T {sub C}. It can be suspected that the introduction of Fe excess in the Fe-Mo sub-lattice, which would lead into the appearance of nearest neighbour Fe-O-Fe antiferromagnetic spin coupling, could reinforce the next-near neighbour Fe-O-Fe-O-Fe ferromagnetic ordering and thus raise the Curie temperature. The plausibility of this mechanism was checked, in the first place, by means of Monte Carlo simulations. Afterwards, Nd{sub 2x}Ca{sub 2-2x}Fe{sub 1+x}Mo{sub 1-x}O{sub 6} series was prepared and fully characterized, being found that the Curie temperature rises as much as {delta}T {sub C} {approx} 75 K when the Fe content is increased. We argue that this is a genuine magnetic exchange effect, not related neither to steric distortions nor band filling.

  8. Ising Critical Behavior of Inhomogeneous Curie-Weiss Models and Annealed Random Graphs

    We study the critical behavior for inhomogeneous versions of the Curie-Weiss model, where the coupling constant {J_{ij}(β)} for the edge {ij} on the complete graph is given by {J_{ij}(β)=β w_iw_j/( {sum_{kin[N]}w_k})}. We call the product form of these couplings the rank-1 inhomogeneous Curie-Weiss model. This model also arises [with inverse temperature {β} replaced by {sinh(β)} ] from the annealed Ising model on the generalized random graph. We assume that the vertex weights {(w_i)_{iin[N]}} are regular, in the sense that their empirical distribution converges and the second moment converges as well. We identify the critical temperatures and exponents for these models, as well as a non-classical limit theorem for the total spin at the critical point. These depend sensitively on the number of finite moments of the weight distribution. When the fourth moment of the weight distribution converges, then the critical behavior is the same as on the (homogeneous) Curie-Weiss model, so that the inhomogeneity is weak. When the fourth moment of the weights converges to infinity, and the weights satisfy an asymptotic power law with exponent {τ} with {τin(3,5)}, then the critical exponents depend sensitively on {τ}. In addition, at criticality, the total spin {S_N} satisfies that {S_N/N^{(τ-2)/(τ-1)}} converges in law to some limiting random variable whose distribution we explicitly characterize.

  9. Characteristics of pediatric hospital medicine fellowships and training programs.

    To explore the structure, components, and training goals of pediatric hospitalist fellowship programs in North America. We constructed a 17-item structured questionnaire to be administered by phone. Questionnaire items focused on documenting goals, training, requirements, and clinical duties of pediatric hospitalist training programs. From February through June 2007, research staff contacted directors of the programs. Responses were analyzed to determine program characteristics, including goals, formal training requirements, clinical rotations, and participation in hospital administrative activities. All 8 training programs completed the survey. There appear to be 2 distinct tracks for pediatric hospitalist training programs: clinical or academic specialization. Currently there are no standards or requirements for fellowship training from an external accrediting body and the curriculum for these programs is likely driven by service requirements and speculation on the needs of a future generation of pediatric hospitalists. The stated goals of the programs were quite similar. Seven reported that the provision of advanced training in the clinical care of hospitalized patients, quality improvement (QI), and hospital administration are central goals of their training program. Six reported training in the education of medical students and residents to be a primary goal, while 5 indicated training in health services research as a primary goal. Pediatric hospitalist fellowships are in the very early stages of their development. In time, greater structure across institutions will need to be put in place if they are to succeed in becoming a necessary prerequisite to the practice of hospital medicine.

    The healthcare workforce is challenged with preparing for the increasing number of older persons and complexities of their healthcare needs. Fellowship trained geriatric dentists are charged with the task of addressing the dental needs of this vastly growing cohort.The purpose of this study is to formulate a set of competencies for Geriatric Dental Fellowship Training Programs. The Delphi technique-a series of three rounds of anonymous questionnaires to obtain the opinions of experts without bringing them together. In Round 1, we proposed 45 competencies based on findings in previous literature. In Round 2, there were 19 respondents whose edits narrowed our list to 39 competencies proposed by the participants. In Round 3, based on group consensus we formulated a final list of 42 competencies. Utilizing the Delphi process, a panel of geriatric dental experts identified a set of core competencies for curriculums in dental fellowship programs. Published 2016.

    ABSTRACT The Accreditation Council for Graduate Medical Education (ACGME) has provided guidance for specialty and subspecialty fellowship training programs by defining 6 core competencies that must be met. Furthermore, the ACGME has defined several program requirements for pathology training, including those applicable to several pathology subspecialties. However, the requirements are broad and lack specific details, particularly as they pertain to the unique nature of pediatric pathology. The Fellowship Committee of the Society for Pediatric Pathology examined the ACGME requirements and interpreted the guidelines with respect to their application to training in pediatric pathology. The Committee worked within the ACGME guidelines to provide an expanded and more comprehensive set of guidelines for use by pediatric pathology fellowship directors and trainees. The resultant document lists the educational goals, core competencies, and program requirements with specific application to pediatric pathology. In addition, methods for assessing and documenting the progress of the individual trainees as they progress through each requirement are provided. It is to be emphasized that many of the guidelines set forthwith are flexible, and allowances should be made for individual differences of each training program.

    A working group at the 2012 Academic Emergency Medicine consensus conference on education research in emergency medicine (EM) convened to develop a curriculum for dedicated postgraduate fellowships in EM education scholarship. This fellowship is intended to create future education scholars, equipped with the skills to thrive in academic careers. This proceedings article reports on the consensus of a breakout session subgroup tasked with defining a common core content for education scholarship fellowships. The authors propose that the core content of an EM education scholarship fellowship can be categorized in four distinct areas: career development, theories of learning and teaching methods, education research methods, and educational program administration. This core content can be incorporated into curricula for education scholarship fellowships in EM or other fields and can also be adapted for use in general medical education fellowships.

    This article reviews trends and issues related to adult nephrology fellowship education in the United States. The number of nephrology fellowship programs and trainees has continued to increase slowly despite limitations in funding of graduate medical education. The use of the Electronic Residency Application System has provided information for the first time on the number, demographics, and behavior of applicants that can be used as baseline data for tracking trends in fellowship applications and for formulating training policies. Issues that nephrology training programs face are discussed in this review: (1) A more stringent graduate medical education regulatory environment, (2) the use of the National Resident Matching Program to enhance the nephrology fellowship applicant selection process, (3) future nephrology workforce shortages, and (4) the continued subspecialization of nephrology. By working together, nephrology fellowship programs can overcome barriers that are raised by these issues and improve the fellowship training experience.

    Thermal demagnetization in the vicinity of the Curie temperature of silver and sodium manganite nanoparticles, as well as copper-nickel and palladium-nickel alloy nanoparticles were studied by both static magnetic measurements and by electron spin resonance (ESR). ESR data indicate that some magnetic ordering remains even above the Curie temperature, determined by static magnetometry. Mechanisms of thermal demagnetization in alloy nanoparticles appear to be different from that in manganites.

    Surgical residents cite increased income potential as a motivation for pursuing fellowship training, despite little evidence supporting this perception. Thus, our goal is to quantify the financial impact of surgical fellowship training on financial career value. By using Medical Group Management Association and Association of American Medical Colleges physician income data, and accounting for resident salary, student debt, a progressive tax structure, and forgone wages associated with prolonged training, we generated a net present value (NPV) for both generalist and subspecialist surgeons. By comparing generalist and subspecialist career values, we determined that cardiovascular (NPV = 698,931), pediatric (430,964), thoracic (239,189), bariatric (166,493), vascular (96,071), and transplant (46,669) fellowships improve career value. Alternatively, trauma (11,374), colorectal (44,622), surgical oncology (203,021), and breast surgery (326,465) fellowships all reduce career value. In orthopedic surgery, spine (505,198), trauma (123,250), hip and joint (60,372), and sport medicine (56,167) fellowships improve career value, whereas shoulder and elbow (4,539), foot and ankle (173,766), hand (366,300), and pediatric (489,683) fellowships reduce career NPV. In obstetrics and gynecology, reproductive endocrinology (352,854), and maternal and fetal medicine (322,511) fellowships improve career value, whereas gynecology oncology (28,101) and urogynecology (206,171) fellowships reduce career value. These data indicate that the financial return of fellowship is highly variable.

    The Internet is a common resource for applicants of hand surgery fellowships, however, the quality and accessibility of fellowship online information is unknown. The objectives of this study were to evaluate the accessibility of hand surgery fellowship Web sites and to assess the quality of information provided via program Web sites. Hand fellowship Web site accessibility was evaluated by reviewing the American Society for Surgery of the Hand (ASSH) on November 16, 2014 and the National Resident Matching Program (NRMP) fellowship directories on February 12, 2015, and performing an independent Google search on November 25, 2014. Accessible Web sites were then assessed for quality of the presented information. A total of 81 programs were identified with the ASSH directory featuring direct links to 32% of program Web sites and the NRMP directory directly linking to 0%. A Google search yielded direct links to 86% of program Web sites. The quality of presented information varied greatly among the 72 accessible Web sites. Program description (100%), fellowship application requirements (97%), program contact email address (85%), and research requirements (75%) were the most commonly presented components of fellowship information. Hand fellowship program Web sites can be accessed from the ASSH directory and, to a lesser extent, the NRMP directory. However, a Google search is the most reliable method to access online fellowship information. Of assessable programs, all featured a program description though the quality of the remaining information was variable. Hand surgery fellowship applicants may face some difficulties when attempting to gather program information online. Future efforts should focus on improving the accessibility and content quality on hand surgery fellowship program Web sites.

    Introduction New paediatric cardiology trainees are required to rapidly assimilate knowledge and gain clinical skills to which they have limited or no exposure during residency. The Pediatric Cardiology Fellowship Boot Camp (PCBC) at Boston Children's Hospital was designed to provide incoming fellows with an intensive exposure to congenital cardiac pathology and a broad overview of major areas of paediatric cardiology practice. The PCBC curriculum was designed by core faculty in cardiac pathology, echocardiography, electrophysiology, interventional cardiology, exercise physiology, and cardiac intensive care. Individual faculty contributed learning objectives, which were refined by fellowship directors and used to build a programme of didactics, hands-on/simulation-based activities, and self-guided learning opportunities. A total of 16 incoming fellows participated in the 4-week boot camp, with no concurrent clinical responsibilities, over 2 years. On the basis of pre- and post-PCBC surveys, 80% of trainees strongly agreed that they felt more prepared for clinical responsibilities, and a similar percentage felt that PCBC should be offered to future incoming fellows. Fellows showed significant increase in their confidence in all specific knowledge and skills related to the learning objectives. Fellows rated hands-on learning experiences and simulation-based exercises most highly. We describe a novel 4-week-long boot camp designed to expose incoming paediatric cardiology fellows to the broad spectrum of knowledge and skills required for the practice of paediatric cardiology. The experience increased trainee confidence and sense of preparedness to begin fellowship-related responsibilities. Given that highly interactive activities were rated most highly, boot camps in paediatric cardiology should strongly emphasise these elements.

    The H-index is increasingly being used as a measure of academic productivity and has been applied to various surgical disciplines. Here the authors calculate the H-index of craniofacial surgery fellowship faculty in North America in order to determine its utility for academic productivity among craniofacial surgeons. A list of fellowship programs was obtained from the website of the American Society of Craniofacial Surgery. Faculty demographics and institution characteristics were obtained from official program websites and the H-index was calculated using Scopus (Elsevier, USA). Data were assessed using bivariate analysis tools (Kruskal-Wallis and Mann-Whitney tests) to determine the relationship between independent variables and career publications, H-index and 5-year H-index (H5-index) of faculty. Dunn test for multiple comparisons was also calculated. A total of 102 faculty members from 29 craniofacial surgery fellowship programs were identified and included. Faculty demographics reflected a median age of 48 (interquartile range [IQR] 13), a predominantly male sample (88/102, 89.7%), and the rank of assistant professor being the most common among faculty members (41/102, 40.2%). Median of career publications per faculty was 37 (IQR 52.5) and medians of H-index and H5-index were 10.0 (IQR 13.75) and 3.5 (IQR 3.25), respectively. Greater age, male gender, Fellow of the American College of Surgeons membership, higher academic rank, and program affiliation with ranked research medical schools were significantly associated with higher H-indices. Variables associated with seniority were positively associated with the H-index. These results suggest that the H-index may be used as an adjunct in determining academic productivity for promotions among craniofacial surgeons.

    In 2007, congenital cardiac surgery became a recognized fellowship by the Accreditation Council of Graduate Medical Education (ACGME) and leads to board certification through the American Board of Thoracic Surgery (ABTS). We highlight the strengths and weaknesses in the current system of accredited training. Data were collected from program directors, the ACGME, and the ABTS. In addition, surveys were sent to training program graduates. Topics included program accreditation status, number of fellows trained per year and per program, match results, fellow operative experience, fellow satisfaction, and post-fellowship employment status. There are twelve active accredited fellowship programs, and 44 trainees have completed accredited training. Each active program has trained a median of 3 fellows (range: 0-7). Operative logs were obtained from 38 of 44 (86%) graduates. The median number of total cases (minimum 75) was 136 (range: 75-236). For complex neonates (minimum 5), the median number of cases was 6 (range: 2-17). Some fellows failed to meet the minimum requirements. Thirty-six (82%) graduates responded to the survey; most were satisfied with their overall operative experience, but less with their neonatal operative experience. Of this total, 84% are currently practicing congenital cardiac surgery, and 74% secured jobs prior to completing their residency. Since 2007, congenital cardiac surgery training has been accredited by the ACGME. In general, the training is uniform, the operative experience is robust, and the fellows are satisfied. Although shortcomings remain, this study highlights the many strengths of the current system. Copyright © 2016 The American Association for Thoracic Surgery. Published by Elsevier Inc.

    The structures of Y2Fe17-xCrx are simulated by the ab initio potentials. The site preference of Cr atom in Y2Fe17 is evaluated and the order is determined as 4f, 12j, which is close to the experimental result. Based on the site preference behavior, the calculated parameters and the atom sites of Y-Fe-Cr system are studied. The result corresponds well to observed data. Further, the DOS of the relaxed structures are calculated and the variation in Curie temperature is explained qualitatively by the spin-fluctuation theory.

    It is well known that the magnetizations as a function of the valence electron number per atom of 3d transition metal substitutional alloys form the so-called Slater-Pauling curve. Similarly, the Curie temperatures of these alloys also show systematic behaviour against the valence electron number. Though this fact has long been known, no attempt has been made so far to explain this behaviour from first principles. In this paper we calculate T(C) of 3d transition metal alloys in the framework of first-principles electronic structure calculation based on the local density approximation.

  5. Curie Temperature of the Intergranular Amorphous Phase in Nanocrystalline Fe89Zr7B4 Alloy

    1999-01-01

    The FeZrB amorphous alloys for simulating the intergranular amorphous phase in the nanocrystalline Fe89Zr7B4 soft magnetic materials were obtained by mechanical alloying of a mixture of elemental Fe, Zr and B powdersfor 25 h. It is shown that the Curie temperature of the simulated intergranular phase alloy is much lower than thatof the intergranular phase with the same chemical composition in the nanocrystalline Fe89Zr7B4 alloy. The possiblemechanism is mainly due to the strong ferromagnetic exchange force among the nanocrystalline α-Fe grains.

    The effect of microscopic Mn cluster distribution on the Curie temperature (Tc) is studied using density-functional calculations. We find that the calculated Tc depends crucially on the microscopic cluster distribution, which can explain the abnormally large variations in experimental Tc values from a few K to well above room temperature. The partially dimerized Mn_2-Mn_1 distribution is found to give the highest Tc > 500 K, and in general, the presence of the Mn_2 dimer has a tendency to enh...

    Copper-nickel (CuNi) alloy nanoparticles with Curie temperatures (T{sub c}) from 40 to 60{sup o}C were synthesized by several techniques. Varying the synthesis parameters and post-treatment, as well as separations by size and T{sub c}, allow producing mediator nanoparticles for magnetic fluid hyperthermia with parametric feedback temperature control with desired parameters. In vitro and in vivo animal experiments have demonstrated the feasibility of the temperature-controlled heating of the tissue, laden with the particles, by an external alternating magnetic field.

    Previous studies have examined possible incentives for pursuing orthopedic fellowship training, but we are unaware of previously published studies reporting the trends in the orthopedic job market since the acceptance of certain criteria for fellowship programs by the Accreditation Council for Graduate Medical Education (ACGME) in 1985. We hypothesized that, since the initiation of accredited postresidency fellowship programs, job opportunities for fellowship-trained orthopedic surgeons have increased and job opportunities for nonfellowship-trained orthopedic surgeons have decreased. We reviewed the job advertisements printed in the Journal of Bone and Joint Surgery, American Volume, for the years 1984, 1994, 2004, and 2009. We categorized the job opportunities as available for either a general (nonfellowship-trained) orthopedic surgeon or a fellowship-trained orthopedic surgeon. Based on the advertisements posted in the Journal of Bone and Joint Surgery, American Volume, a trend exists in the orthopedic job market toward seeking fellowship-trained orthopedic surgeons. In the years 1984, 1994, 2004, and 2009, the percentage of job opportunities seeking fellowship-trained orthopedic surgeons was 16.7% (95% confidence interval [CI], 13.1%-20.3%), 40.6% (95% CI, 38.1%-43.1%), 52.2% (95% CI, 48.5%-55.9%), and 68.2% (95% CI, 65.0%-71.4%), respectively. These differences were statistically significant (analysis of variance, P<.05). Fellowship training is thus a worthwhile endeavor.

    The Orthopaedic Fellowship Match was established in 2008 to streamline and improve the process of matching residents and fellowships. The purpose of this study was to quantify the factors that affect the application process and to determine how residents establish a rank list. The Orthopaedic Fellowship Match has improved the ability of residents and programs to consider their options more carefully and to focus on finding the best match. However, this process introduces new factors for all parties involved to consider. The costs of the interview process and time away from service for residents may be larger than anticipated. Ultimately, residents value operative experience and staff members at a fellowship more than all other factors when selecting a fellowship.

    2014-10-01

    During yearly meetings of the recently developed network of 15 public/community psychiatry fellowships, it has been noted that programs are having varying degrees of success with regard to recruitment. To understand factors that impact recruitment, a quality improvement survey of fellows and alumni was conducted. Respondents were asked to rate overall satisfaction with their fellowship training as well as perceived benefits and obstacles to participating in a fellowship program, and impact on their careers. A total of 155 (57%) fellows and alumni responded. Factor analysis was used to condense the variables, and a multiple regression explored factors predicting overall fellowship program satisfaction. Factors that represented perceived benefits had higher means than did factors that represent obstacles. Respondents highly valued the extent to which these fellowships enhanced their careers, with regard to job opportunities, academics, networking and leadership.

    The possibility of employing the ferromagnetic–paramagnetic phase transitions of magnetic materials to calibrate temperature during spark plasma sintering (SPS) was investigated using pure Fe and Fe–50Co alloy. A sharp and repeatable change was observed in the electrical current profile at the Curie temperature (T{sub c}) during both sintering and reheating of the sintered samples. Under a pulsed DC current, an abrupt change in the electrical resistance was observed at T{sub c} due to the sudden changes in the permeability and in turn, the skin depth during heating and cooling. These effects can be used to obtain a more accurate in-situ measurement of the sample temperature than the one provided by the pyrometers that are normally used for SPS processing. The temperature measured using a pyrometer was found to be significantly lower (up to 70 °C) than the actual temperature of the specimen. - Highlights: • Calibration of temperature during spark plasma sintering (SPS) remains a big challenge. • Temperature measured by non-contact pyrometers in SPS is not accurate. • Ferromagnetic materials exhibit abrupt change in permeability at Curie temperature (T{sub c}). • Iron and Fe–Co alloy showed sharp and reproducible changes in SPS electric current profiles at T{sub c}. • Ferromagnetic materials can be successfully used to calibrate pyrometers in SPS.

    N-doped graphene with Curie temperature higher than room temperature is a good candidate for nanomagnetic applications. Here we report a kind of N-doped graphene that exhibits ferromagnetic property with high Curie temperature (>600 K). Four graphene samples were prepared through self-propagating high-temperature synthesis (SHS), and the doped nitrogen contents of in the samples were 0 at.%, 2.53 at.%, 9.21 at.% and 11.17 at.%. It has been found that the saturation magnetization and coercive field increase with the increasing of nitrogen contents in the samples. For the sample with the highest nitrogen content, the saturation magnetizations reach 0.282 emu/g at 10 K and 0.148 emu/g at 300 K; the coercive forces reach 544.2 Oe at 10 K and 168.8 Oe at 300 K. The drop of magnetic susceptibility at ~625 K for N-doped graphene is mainly caused by the decomposition of pyrrolic N and pydinic N. Our results suggest that SHS method is an effective and high-throughput method to produce N-doped graphene with high nitrogen concentration and that N-doped graphene produced by SHS method is promising to be a good candidate for nanomagnetic applications.

    A series of nickel–copper alloy magnetic nanoparticles with a range of Curie points from 51 °C to 63 °C were prepared by the reduction of intimately mixed nickel and copper oxides in a silica matrix using the sol–gel method. The silica matrix was subsequently removed with an etching solution, assisted by sonication. The alloy nanoparticles were characterized using X-ray diffraction (XRD) analysis, thermogravimetric analysis (TGA/SDTA), thermomagnetic analysis (TMA), transmission electron microscopy (TEM), magnetic measurements (SQUID, vibrating-sample magnetometer) and specific absorption rate measurements (SAR). The synthesized nanoparticles show a size in the range 15–20 nm, exhibited superparamagnetic behavior with a blocking temperature (T{sub B}) of approximately 135 K and a room-temperature magnetization of 3–9 emu/g, depending on the composition. The nanoparticles showed a relatively high effective anisotropy constant (K{sub eff}) and a significant heating ability in an alternating magnetic field. The synthesis method is straightforward and allows the preparation of homogeneous Ni–Cu alloy nanoparticles with a relatively narrow particle size distribution. - Highlights: • Straightforward so-gel synthesis of homogeneous Ni–Cu alloy nanoparticles. • Narrow particle size distribution and controlled Curie point. • Applications in “self-regulating magnetic fluid hyperthermia”. • Heating efficiency of nanoparticles as a function of composition and size.

    Educational needs assessments for nephrology fellowship training are limited. This study assessed fellows' perceptions of current educational needs and interest in novel modalities that may improve their educational experience and quantified educational resources used by programs and fellows. We distributed a seven-question electronic survey to all United States-based fellows receiving complimentary American Society of Nephrology (ASN) membership at the end of the 2015-2016 academic year in conjunction with the ASN Nephrology Fellows Survey. One third (320 of 863; 37%) of fellows in Accreditation Council for Graduate Medical Education-accredited positions responded. Most respondents rated overall quality of teaching in fellowship as either "good" (37%) or "excellent" (44%), and most (55%) second-year fellows felt "fully prepared" for independent practice. Common educational resources used by fellows included UpToDate, Journal of the American Society of Nephrology/Clinical Journal of the American Society of Nephrology, and Nephrology Self-Assessment Program; others-including ASN's online curricula-were used less often. Fellows indicated interest in additional instruction in several core topics, including home dialysis modalities, ultrasonography, and pathology. Respondents strongly supported interventions to improve pathology instruction and increase time for physiology and clinical review. In conclusion, current nephrology fellows perceive several gaps in training. Innovation in education and training is needed to better prepare future nephrologists for the growing challenges of kidney care. Copyright © 2017 by the American Society of Nephrology.

    Postdoctoral pharmacy industry fellowship programs and the employment of fellowship graduates are described. A list of postgraduate industry fellowships was gathered from the 2009 ASHP Midyear Clinical Meeting. Data regarding program characteristics were collected using the Personnel Placement Service database and program-specific brochures. After data compilation, a standardized survey was sent in January 2010 via e-mail to the point of contact for all programs to confirm the accuracy of the program's characteristics. Only academically affiliated industry fellowship programs were analyzed. Retrospective data were collected regarding the first position of employment for all fellows who graduated from the program between 2005 and 2009 and the position of those same individuals at the time of survey completion. Surveys were sent to 64 postgraduate industry fellowship programs affiliated with a school of pharmacy, 56 (87.5%) of whom responded. The departmental breakdown for positions offered (n = 75) across all academically affiliated industry fellowship programs (including nonresponders) was as follows: medical affairs (38.7%, n = 29), clinical research (32.0%, n = 24), regulatory affairs (9.3%, n = 7), commercial (8.0%, n = 6), health economics and outcomes research (8.0%, n = 6), and pharmacovigilance (4.0%, n = 3). Data from fellows during years 1-5 after completion of the industry fellowship indicated that 90.5% of former fellows remained in the industry (n = 238). The postgraduate industry fellowship programs surveyed indicated that the majority of fellowship graduates continued to hold positions in industry after program completion. The majority of industry fellowships and subsequent job placements occurred in the areas of medical affairs, clinical research, and regulatory affairs.

    Ground and aeromagnetic data are combined to characterize the onshore and offshore magnetic properties of the central Philippines, whose tectonic setting is complicated by opposing subduction zones, large-scale strike-slip faulting and arc-continent collision. The striking difference between the magnetic signatures of the islands with established continental affinity and those of the islands belonging to the island arc terrane is observed. Negative magnetic anomalies are registered over the continental terrane, while positive magnetic anomalies are observed over the Philippine Mobile Belt. Several linear features in the magnetic anomaly map coincide with the trace of the Philippine Fault and its splays. Power spectral analysis of the magnetic data reveals that the Curie depth across the central Philippines varies. The deepest point of the magnetic crust is beneath Mindoro Island at 32 km. The Curie surface shallows toward the east: the Curie surface is 21 km deep between the islands of Sibuyan and Masbate, and 18 km deep at the junction of Buruanga Peninsula and Panay Island. The shallowest Curie surface (18 km) coincides with the boundary of the arc-continent collision, signifying the obduction of mantle rocks over the continental basement. Comparison of the calculated Curie depth with recent crustal thickness models reveals the same eastwards thinning trend and range of depths. The coincidence of the magnetic boundary and the density boundary may support the existence of a compositional boundary that reflects the crust-mantle interface.

  5. Giant magnetocaloric effect in isostructural MnNiGe-CoNiGe system by establishing a Curie-temperature window

    Liu, E. K.

    2013-03-28

    An effective scheme of isostructural alloying was applied to establish a Curie-temperature window in isostructural MnNiGe-CoNiGe system. With the simultaneous accomplishment of decreasing structural-transition temperature and converting antiferromagnetic martensite to ferromagnetic state, a 200 K Curie-temperature window was established between Curie temperatures of austenite and martensite phases. In the window, a first-order magnetostructural transition between paramagnetic austenite and ferromagnetic martensite occurs with a sharp jump in magnetization, showing a magnetic entropy change as large as −40 J kg−1 K−1 in a 50 kOe field change. This giant magnetocaloric effect enables Mn1− x Co x NiGe to become a potential magnetic refrigerant.

    Curie-therapy conventionally comes before surgery in the treatment of cervical cancer, either alone or after a concomitant chemotherapy. The authors report a study of the impact of a reverse sequence (surgery before curie-therapy) on the exeresis quality and on the evolution of operable tumours. Among women treated between 2004 and 2009, 40 have been identified who had surgery before curie-therapy. Ages, tumour stages, average doses, and treatment procedures are discussed. The notably high rate of vaginal sections could be reduced or avoided by using the conventional protocol (curie-therapy before surgery). Short communication

    @@ Above Curie temperature, MnBi crystals are aligned in situ along the c-axis in a Bi matrix by a high fabrication magnetic field Hf of 10 T. Magnetic testing shows a pronounced anisotropy in magnetization in directions normal and parallel to the fabrication field, resulting from the alignment. The successful alignment may result from the fact that the easy magnetization direction is along the c-axis of MnBi and the high fabrication field of 10 T is large enough to rotate the MnBi crystal to this direction even though the temperature is above the Curie temperature.

    Interest in emergency radiology as a distinct subspecialty within radiology continues to rise in the USA and globally. While acute care imaging has been performed since the earliest days of the specialty, fellowship training in emergency radiology is a relatively new phenomenon. The purpose of this study was to examine the current status of emergency radiology training in the USA, using data derived from the official websites of US residency training programs. The most current list of radiology residency programs participating in the 2017 match was obtained from the official Electronic Residency Application Service (ERAS) website. The total number of emergency radiology fellowships was recorded after visiting available websites of each academic radiology program. The total number of subspecialty fellowships offered by each academic radiology program was also recorded. There were 12 confirmed emergency radiology fellowships offered in the USA for a combined total of 22 fellowship positions. Eleven programs were 1 year in duration, with one program offering a one- or two-year option. One hundred eight of the 174 (approximately 62 %) surveyed academic radiology programs offered at least one subspecialty fellowship. Emergency radiology fellowships are on the rise, paralleling the growth of emergency radiology as a distinct subspecialty within radiology.

    The physical therapy profession continues to respond to the complex and changing landscape of health care to meet the needs of patients and the demands of patient care. Consistent with this evolution is the rapid development and expansion of residency and fellowship postprofessional programs. With the interested number of applicants exceeding the number of residency and fellowship slots available, a "critical period" in the educational process is emerging. The purposes of this perspective article are: (1) to analyze the state of residency and fellowship education within the profession, (2) to identify best practice elements from other health professions that are applicable to physical therapy residency and fellowship education, and (3) to propose a working framework grounded in common domains of competence to be used as a platform for dialogue, consistency, and quality across all residency and fellowship programs. Seven domains of competence are proposed to theoretically ground residency and fellowship programs and facilitate a more consistent approach to curricular development and assessment. Although the recent proliferation of residency and fellowship programs attempts to meet the demand of physical therapists seeking advanced educational opportunities, it is imperative that these programs are consistently delivering high-quality education with a common focus on delivering health care in the context of societal needs. © 2016 American Physical Therapy Association.

    Full Text Available Orthopedic residents have one of the highest fellowship participation rates among medical specialities and there are growing concerns that inadequate residency training may be contributing to this trend. Therefore, a mixed-exploratory research survey was distributed to all 148 graduating Canadian orthopedic residents to investigate their perceptions and attitudes for pursuing fellowships. A response rate of 33% (n=49 was obtained with the majority of residents undertaking one (27% or two (60% fellowships. Surgical-skill development was reported as the most common motivating factor, followed by employment and marketability; malpractice protection and financial reasons were the least relevant. The overwhelming majority of residents (94%, n=46 felt adequately prepared by their residency training for independent general practice, and 84% (n=41 of respondents did not feel that current fellowship trends were due to poor residency training. Three common themes were expressed in their comments: the growing perceived expectation by healthcare professionals and employers to be fellowship-certified, the integration of fellowship training into the surgical education hierarchy, and the failure of residency training curriculums to accommodate for this trend. In conclusion, Canadian orthopedic residents are confident of their residency training and are increasingly pursuing fellowships to primarily develop their surgical skills and expertise.

    This study describes characteristics and the evolution of the careers of graduates from a 1-year post-residency fellowship program whose primary objectives included clinical skills in Cesarean section. Besides obstetrical practice, rural service and attainment of faculty appointment were used as surrogate measures of fulfilling an underserved need for family medicine obstetrics. For 18 years, the authors maintained contact with all 80 physicians completing 1-year fellowships in family medicine obstetrics in Memphis and Nashville. The founding chair of these programs surveyed each physician and maintained a network of contacts to study outcomes such as graduation, service location, hospital privileges, retention, and career changes. The study tracked 100% of the sample and documented high rates of fellowship completion (74/80 [93%]), Cesarean privileges (71/74 [96%]), and service in a rural community for at least 2 years (47/74 [64%]). The fellowship was also associated with participation as faculty (36/74 [46%]). This paper produces the first and longest-term data describing attrition over time and examines the reasons why fellowship-trained family physicians stop doing maternity care. It is the only series with a 100% response rate and provides longitudinal data on the outcomes of these fellowship programs. Attrition was highest at rural sites. Workforce planners and fellowship designers might benefit from these considerations.

  16. Resident interest and factors involved in entering a pediatric pulmonary fellowship

    2004-07-01

    Full Text Available Abstract Background Relatively little is known about interest in pediatric pulmonology among pediatric residents. The purpose of this study, therefore, was to determine at this institution: 1 the level of pediatric resident interest in pursuing a pulmonary fellowship, 2 potential factors involved in development of such interest, 3 whether the presence of a pulmonary fellowship program affects such interest. Methods A questionnaire was distributed to all 52 pediatric residents at this institution in 1992 and to all 59 pediatric residents and 14 combined internal medicine/pediatrics residents in 2002, following development of a pulmonary fellowship program. Results Response rates were 79% in 1992 and 86% in 2002. Eight of the 43 responders in 1992 (19% had considered doing a pulmonary fellowship compared to 7 of 63 (11% in 2002. The highest ranked factors given by the residents who had considered a fellowship included wanting to continue one's education after residency, enjoying caring for pulmonary patients, and liking pulmonary physiology and the pulmonary faculty. Major factors listed by residents who had not considered a pulmonary fellowship included not enjoying the tracheostomy/ventilator population and chronic pulmonary patients in general, and a desire to enter general pediatrics or another fellowship. Most residents during both survey periods believed that they would be in non-academic or academic general pediatrics in 5 years. Only 1 of the 106 responding residents (~1% anticipated becoming a pediatric pulmonologist. Conclusions Although many pediatric residents consider enrolling in a pulmonary fellowship (~10–20% here, few (~1% here will actually pursue a career in pediatric pulmonology. The presence of a pulmonary fellowship program did not significantly alter resident interest, though other confounding factors may be involved.

    The study aimed to examine the postresidency plans of Canadian radiology residents and factors influencing their fellowship choices and practice preferences, including interest in teaching and research. Institutional ethics approval was obtained at McMaster University. Electronic surveys were sent to second to fifth-year residents at all 16 radiology residency programs across Canada. Each survey assessed factors influencing fellowship choices and practice preferences. A total of 103 (31%) Canadian radiology residents responded to the online survey. Over 89% from English-speaking programs intended to pursue fellowship training compared to 55% of residents from French-speaking programs. The most important factors influencing residents' decision to pursue fellowship training were enhanced employability (46%) and personal interest (47%). Top fellowship choices were musculoskeletal imaging (19%), body imaging (17%), vascular or interventional (14%), neuroradiology (8%), and women's imaging (7%). Respondents received the majority of their fellowship information from peers (68%), staff radiologists (61%), and university websites (58%). Approximately 59% planned on practicing at academic institutions and stated that lifestyle (43%), job prospects (29%), and teaching opportunities (27%) were the most important factors influencing their decisions. A total of 89% were interested in teaching but only 46% were interested in incorporating research into their future practice. The majority of radiology residents plan on pursuing fellowship training and often receive their fellowship information from informal sources such as peers and staff radiologists. Fellowship directors can incorporate recruitment strategies such as mentorship programs and improving program websites. There is a need to increase resident participation in research to advance the future of radiology. Copyright © 2016 Canadian Association of Radiologists. Published by Elsevier Inc.

    Background The present study was conducted to assess the preparedness of hepatopancreatobiliary (HPB) fellows upon entering fellowship, identify challenges encountered by HPB fellows during the initial part of their HPB training, and identify potential solutions to these challenges that can be applied during residency training. Methods A questionnaire was distributed to all HPB fellows in accredited HPB fellowship programmes in two consecutive academic years (n = 42). Reponses were then analysed. Results A total of 19 (45%) fellows responded. Prior to their fellowship, 10 (53%) were in surgical residency and the rest were in other surgical fellowships or surgical practice. Thirteen (68%) were graduates of university-based residency programmes. All fellows felt comfortable in performing basic laparoscopic procedures independently at the completion of residency and less comfortable in performing advanced laparoscopy. Eight (42%) fellows cited a combination of inadequate case volume and lack of autonomy during residency as the reasons for this lack of comfort. Thirteen (68%) identified inadequate preoperative workup and management as their biggest fear upon entering practice after general surgery training. A total of 17 (89%) fellows felt they were adequately prepared to enter HPB fellowship. Extra rotations in transplant, vascular or minimally invasive surgery were believed to be most helpful in preparing general surgery residents pursing HPB fellowships. Conclusions Overall, HPB fellows felt themselves to be adequately prepared for fellowship. Advanced laparoscopic procedures and the perioperative management of complex patients are two of the challenges facing HPB fellows. General surgery residents who plan to pursue an HPB fellowship may benefit from spending extra rotations on certain subspecialties. Focus on perioperative workup and management should be an integral part of residency and fellowship training. PMID:25387852

    2015-01-15

    We report the discovery of ternary CeFe(12-x)Si(x)compounds possessing the ThMn12 structure. The samples were prepared by melt spinning followed by annealing. In contrast to other known Ce Fe-based binary and ternary compounds, CeFe12-xSix compounds exhibit exceptionally high Curie temperatures whose values increase with added Si substitution. The highest T. = 583 K in CeFe10Si2 rivals that of the well-established Nd2Fe14B compound. We ascribe the T-c behavior to a combination of Si-induced 3d band structure changes and partial Ce3+ stabilization. (C) 2014 Published by Elsevier Ltd.

    Polycrystalline Mn5Ge3 thin films were produced on SiO2 using magnetron sputtering and reactive diffusion (RD) or non-diffusive reaction (NDR). In situ X-ray diffraction and atomic force microscopy were used to determine the layer structures, and magnetic force microscopy, superconducting quantum interference device, and ferromagnetic resonance were used to determine their magnetic properties. RD-mediated layers exhibit similar magnetic properties as molecular beam epitaxy-grown monocrystalline Mn5Ge3 thin films, while NDR-mediated layers show magnetic properties similar to monocrystalline C-doped Mn5Ge3Cx thin films with 0.1 ≤ x ≤ 0.2. NDR appears as a complementary metal oxide semi-conductor-compatible efficient method to produce good magnetic quality high-Curie temperature Mn5Ge3 thin films.

  1. Nd-doped ZnO monolayer: High Curie temperature and large magnetic moment

    2016-10-01

    We performed first-principles calculations within density-functional theory to study the structural, electronic, and magnetic properties of Nd-doped ZnO monolayer. The calculated results reveal that Nd-doped ZnO monolayer exhibits stable room temperature ferromagnetism with a large saturation magnetic moment of 3.99 μB per unit in ZnO monolayer. The magnetic property is contributed to the localized f sates of Nd atoms. When two Zn atoms are substituted by two Nd dopants, they tend to form ferromagnetic (FM) coupling and the estimated Curie temperature is higher than room temperature. More interesting, the impurity bands appear within the band gap of ZnO monolayer due to the introduction of Nd dopant. Our results may provide a reference for modifying the material property of ZnO monolayer and are promising as nanoscale building block in spintronic devices.

    The article presents from the perspective of one hundred years the work of Maria Curie-Skłodowska, which in many cases was ahead of the state of knowledge of the time. It opened new horizons and for this reason we made many digressions. The fact of awarding her the Nobel Prize twice is a sensation enough to present the values of careful activity of the Nobel Prize Committee that emphasizes the importance of Maria's achievements. A significant element of Maria Skłodowska-Curie's achievements was still mysterious character of the radiation in her time, and only chemical approach made it possible to organise the phenomena and explain the origin of the radiation. The essence of the research was an arduous separation of components following the track of growing radiation of successive fractions of preparations. This research was a start of the technology of educement of dispersed elements in great mass of materials. We underline the paramount role of the chemical research Maria Skłodowska conducted while still in Warsaw in the laboratories of the Museum of Industry and Agriculture under the guidance of an excellent chemist Józef Jerzy Boguski. Her research in Paris was the origin of the semi-commercial scale in chemistry and setting aside a special shed outside the university building was the beginning of the institutes that now function beyond universities and are key element of scientific and technical progress. Technology of splitting developed by Maria Skłodowska-Curie was applied also by other radiochemists, e.g. By Otto Hahn. Lively movement in radiochemistry of her lifetime resulted in Maria's disputes with e.g. German chemist Marckwald, who questioned the originality of polonium. The scientific disputes like this one Maria won triumphantly although in several others she had to accept opponents' argument, as in the case of radon. Her experiments were planned with utmost rationality as it was with the rejection of the hypothesis saying that radioactivity was

    In the early part of the 20th century, the pioneers of radioactivity research, led by Marie Curie, Ernest Rutherford and Stefan Meyer, formed a Commission internationale des étalons de radium. The Commission made arrangements for the preparation and intercomparisons of the international standards of radium, which were identified as the Paris standard and the Vienna standard. Otto Hönigschmid from Vienna prepared a first set of international secondary standards in 1912 and a second set in 1934. In both instances, these secondary standards were compared by gamma-ray measurements with the Paris and Vienna standards. The usage of these international standards of radium in the 20th century is described.

    2016-04-01

    The thermal decomposition behavior of terephthalic acid (TA) was investigated by thermogravimetry/differential thermal analysis (TG/DTA) and Curie-point pyrolysis. TG/DTA analysis showed that TA is sublimed at 276°C prior to decomposition. Pyrolysis studies were carried out at various temperatures ranging from 160 to 764°C. Decomposition products were analyzed and their structures were determined by gas chromatography-mass spectrometry (GC-MS). A total of 11 degradation products were identified at 764°C, whereas no peak was observed below 445°C. Benzene, benzoic acid, and 1,1‧-biphenyl were identified as the major decomposition products, and other degradation products such as toluene, benzophenone, diphenylmethane, styrene, benzaldehyde, phenol, 9H-fluorene, and 9-phenyl 9H-fluorene were also detected. A pyrolysis mechanism was proposed based on the findings.

  12. Mapping Curie temperature depth in the western United States with a fractal model for crustal magnetization

    2009-01-01

    We have revisited the problem of mapping depth to the Curie temperature isotherm from magnetic anomalies in an attempt to provide a measure of crustal temperatures in the western United States. Such methods are based on the estimation of the depth to the bottom of magnetic sources, which is assumed to correspond to the temperature at which rocks lose their spontaneous magnetization. In this study, we test and apply a method based on the spectral analysis of magnetic anomalies. Early spectral analysis methods assumed that crustal magnetization is a completely uncorrelated function of position. Our method incorporates a more realistic representation where magnetization has a fractal distribution defined by three independent parameters: the depths to the top and bottom of magnetic sources and a fractal parameter related to the geology. The predictions of this model are compatible with radial power spectra obtained from aeromagnetic data in the western United States. Model parameters are mapped by estimating their value within a sliding window swept over the study area. The method works well on synthetic data sets when one of the three parameters is specified in advance. The application of this method to western United States magnetic compilations, assuming a constant fractal parameter, allowed us to detect robust long-wavelength variations in the depth to the bottom of magnetic sources. Depending on the geologic and geophysical context, these features may result from variations in depth to the Curie temperature isotherm, depth to the mantle, depth to the base of volcanic rocks, or geologic settings that affect the value of the fractal parameter. Depth to the bottom of magnetic sources shows several features correlated with prominent heat flow anomalies. It also shows some features absent in the map of heat flow. Independent geophysical and geologic data sets are examined to determine their origin, thereby providing new insights on the thermal and geologic crustal

    2015-12-01

    Barium ferrite has attracted considerable interest in the fields of permanent magnets and perpendicular magnetic recording due to its strong uniaxial anisotropy and high Curie temperature (T{sub c}). We prepared aluminum doped barium ferrite ceramics (BaAl{sub x}Fe{sub 12−x}O{sub 19}, 0≤x≤6) by the ball mill method. The powder was milled for 96 h, and after forming pellets, annealed for 48 h in air at 1000 °C. The X-ray diffraction (XRD) data show that there are only single hexagonal phases in the samples without any impurity phase. The crystal lattice constants, a and c, were calculated by Cohen's method. Both a and c decrease with increasing x, ranging from 0.588 nm and 2.318 nm to 0.573 nm and 2.294 nm, respectively. A Vibrating Sample Magnetometer (VSM) and Superconducting Quantum Interference Device (SQUID) were used to investigate T{sub c} and magnetic properties of BaFe{sub 12−x}Al{sub x}O{sub 19}. It is found that T{sub c} decreases with increasing x, from 425 °C to 298 °C. It is also found that the saturated magnetization (4πM{sub s}) decreases with increasing x, while the coercivity (H{sub c}) increases with the increase in x. The anisotropy field was also determined from the SQUID measurement. - Highlights: • The Curie temperature and magnetic properties of aluminum doped barium ferrite particles were studied systemically. • The relation between 4πM{sub s} and composition x at 50 K (both experimental value and theoretical calculation) was revealed. • Occupation number for spin up and spin down as a function of temperature was shown. • The relation between 4πM{sub s} and composition x from 50 K to room temperature was revealed.

    Rutile CrO2 is an important half-metallic ferromagnetic material, which is also widely used in magnetic recording. In an attempt to find the conditions, which lead to the increase of the Curie temperature (T C), we study theoretically the band-filling dependence of interatomic exchange interactions in the rutile compounds. For these purposes, we use the effective low-energy model for the magnetic t 2g bands, derived from the first-principles electronic structure calculations in the Wannier basis, which is solved by means of dynamical mean-field theory. After the solution, we calculate the interatomic exchange interactions, by using the theory of infinitesimal spin rotations, and evaluate T C. We argue that, as far as the Curie temperature is concerned, the band filling realized in CrO2 is far from being the optimal one and much higher T C can be obtained by decreasing the number of t 2g electrons (n) via the hole doping. We find that the optimal n is close to 1, which should correspond to the case of VO2, provided that it is crystallized in the rutile structure. This finding was confirmed by using the experimental rutile structure for both CrO2 and VO2 and reflects the general tendency towards ferromagnetism for the narrow-band compounds at the beginning of the band filling. In particular, our results suggest that the strong ferromagnetism can be achieved in the thin films of VO2, whose crystal structure is controlled by the substrate.

    With funding from an NSF Informal Science Education grant, the Pacific Science Center in Seattle, Washington began the Science Communication Fellowship program in 2009 as part of the Portal to the Public initiative. The purpose of the Science Communication Fellowship program is to train scientists and engineers to communicate more effectively with the general public regarding their research and to assist with the development of hands-on activities that can be used by the scientists and engineers for outreach activities. The program came out of a collaboration to develop a model for effectively communicating current science research at informal science education organizations. The program model has undergone in-depth research and evaluation to assess its effectiveness and impact. To become Science Communication Fellows, researchers participate in four three-hour professional development sessions, where they learn communication techniques through role-playing and hands-on activities. The workshops are supplemented with additional one-on-one meetings with Science Center staff to help the new Fellows develop activities for use at outreach events. These activities are then used by the Fellows at public events that highlight current research taking place in the region. To date over 80 scientists and engineers have gone through the training sessions to become Science Communication Fellows. The Pacific Science Center holds approximately 12 events a year in which Fellows can facilitate their activity. Public programs range from small, monthly programs to large, annual Research Weekends. Funding for this program continues through support from NIH, IMLS, NSF, and NASA grants.

    Yap, Stanley A; Ellison, Lars M; Low, Roger K

    2008-08-01

    Laparoscopic surgery is now an integral technique in the practice of urology, particularly in the management of certain urologic malignancies. Advanced laparoscopy training in urology is primarily reserved for those pursuing fellowship training and is offered both by traditional endourology fellowships and increasingly in urologic oncology fellowships. The purpose of our study was to evaluate and compare current laparoscopy training at the fellowship level. A 17-item questionnaire was developed with support from both the Endourological Society (EUS) and Society of Urologic Oncology (SUO). Surveys were sent to program directors of fellowships recognized by the EUS and SUO. Directors were surveyed on the laparoscopic case volume, degree of oncology training, and career choice of their graduates. Data were analyzed with Wilcoxon rank-sum and Student t tests. Our survey had an overall response rate of 60%. Fellows performed more than 100 laparoscopies during their training period in 57% of EUS and 25% of SUO fellowship programs. Similar trends are demonstrated when analyzing robotic procedures, with 73% of EUS fellows performing more than 50 procedures compared with 43% of SUO fellows. The majority (59%) of EUS programs provide oncologic training. Between 44% and 100% of graduates from EUS and SUO fellowships obtain academic positions. The majority of SUO directors (63%) believe that fellowship training in laparoscopy should be provided in fellowships governed solely by the SUO, while 41% of EUS directors believe this training should be governed solely by the EUS. Endourology fellowships currently provide a greater exposure to laparoscopy and robotics than SUO fellowships. The percentage of fellows seeking academic positions is similar for EUS and SUO fellowship programs and has remained stable for several years. Directors of fellowship programs that offer advanced laparoscopic training have divergent views as to which administrative body should govern its future.

    To describe common facilitators, challenges, and lessons learned in 5 schools and colleges of pharmacy in establishing community pharmacy research fellowships. Five schools and colleges of pharmacy in the United States. Schools and colleges of pharmacy with existing community partnerships identified a need and ability to develop opportunities for pharmacists to engage in advanced research training. Community pharmacy fellowships, each structured as 2 years long and in combination with graduate coursework, have been established at the University of Pittsburgh, Purdue University, East Tennessee State University, University of North Carolina at Chapel Hill, and The Ohio State University. Program directors from each of the 5 community pharmacy research fellowships identified common themes pertaining to program structure, outcomes, and lessons learned to assist others planning similar programs. Common characteristics across the programs include length of training, prerequisites, graduate coursework, mentoring structure, and immersion into a pharmacist patient care practice. Common facilitators have been the existence of strong community pharmacy partnerships, creating a fellowship advisory team, and networking. A common challenge has been recruitment, with many programs experiencing at least one year without filling the fellowship position. All program graduates (n = 4) have been successful in securing pharmacy faculty positions. Five schools and colleges of pharmacy share similar experiences in implementing community pharmacy research fellowships. Early outcomes show promise for this training pathway in growing future pharmacist-scientists focused on community pharmacy practice. Copyright © 2016 American Pharmacists Association®.

    Full Text Available Background. There are currently 34 International Emergency Medicine (IEM fellowship programs. Applicants and programs are increasing in number and diversity. Without a standardized application, applicants have a difficulty approaching programs in an informed and an organized method; a streamlined application system is necessary. Objectives. To measure fellows’ knowledge of their programs’ curricula prior to starting fellowship and to determine what percent of fellows and program directors would support a universal application system. Methods. A focus group of program directors, recent, and current fellows convened to determine the most important features of an IEM fellowship application process. A survey was administered electronically to a convenience sample of 78 participants from 34 programs. Respondents included fellowship directors, fellows, and recent graduates. Results. Most fellows (70% did not know their program’s curriculum prior to starting fellowship. The majority of program directors and fellows support a uniform application service (81% and 67%, resp. and deadline (85% for both. A minority of program directors (35% and fellows (30% support a formal match. Conclusions. Program directors and fellows support a uniform application service and deadline, but not a formalized match. Forums for disseminating IEM fellowship information and for administering a uniform application service and deadline are currently in development to improve the process.

    The Hydro Fellowship Program (program) began as an experiment to discover whether the hydropower industry could find mechanisms to attract new entrants through conducting relevant research to benefit the industry. This nationwide, new-to-the-world program was started through funding from the Wind and Water Power Technologies Office of the Energy Efficiency and Renewable Energy (EERE) Office of the Department of Energy (DOE). Between 2010-2015, the Hydro Research Foundation (HRF) designed and implemented a program to conduct valuable research and attract new entrants to the hydro workforce. This historic grant has empowered and engaged industry members from 25 organizations by working with 91 students and advisors at 24 universities in 19 states. The work funded answered pressing research needs in the fields of civil, mechanical, environmental, and electrical engineering, as well as law, energy engineering and materials innovation. In terms of number of individuals touched through funding, 148 individuals were supported by this work through direct research, mentorship, oversight of the work, partnerships and the day-to-day program administration. Based on the program results, it is clear that the funding achieved the hoped-for outcomes and has the capacity to draw universities into the orbit of hydropower and continue the conversation about industry research and development needs. The Foundation has fostered unique partnerships at the host universities and has continued to thrive with the support of the universities, advisors, industry and the DOE. The Foundation has demonstrated industry support through mentorships, partnerships, underwriting the costs and articulating the universities’ support through in-kind cost sharing. The Foundation recommends that future work be continued to nurture these graduate level programs using the initial work and improvements in the successor program, the Research Awards Program, while stimulating engagement of academia at the

    The emerging field of spintronics would be dramatically boosted if room-temperature ferromagnetism could be added to semiconductor nanostructures that are compatible with silicon technology. Here, we report a high-TC (>400K) ferromagnetic phase of (Ge,Mn) epitaxial layer. The manganese content is 6%, and careful structural and chemical analyses show that the Mn distribution is strongly inhomogeneous: we observe eutectoid growth of well-defined Mn-rich nanocolumns surrounded by a Mn-poor matrix. The average diameter of these nanocolumns is 3nm and their spacing is 10nm. Their composition is close to Ge(2)Mn, which corresponds to an unknown germanium-rich phase, and they have a uniaxially elongated diamond structure. Their Curie temperature is higher than 400K. Magnetotransport reveals a pronounced anomalous Hall effect up to room temperature. A giant positive magnetoresistance is measured from 7,000% at 30K to 200% at 300K and 9T, with no evidence of saturation.

    The opening of the Drake Passage, situated between South America and Antarctica, represents the final stage of the fragmentation of Gondwana supercontinent. It led to the Scotia Arc formation, bordering the Scotia Sea, which is surrounded by fragments of the former continental connection. It is currently composed of Scotia and Sandwich Plates. Shackleton Fracture Zone constitutes its sinistral transpressive western boundary and it is a key structure that accommodates former Phoenix and Scotia Plates' differential movement. The formation of the Drake Passage and the Scotia Sea is considered of great importance to ocean circulation, as it allows the establishment of the Antarctic Circumpolar Current that isolated the Antarctic continent, with strong implications for climate and global changes. Thermal structure of the Earth's crust is one of the main parameters controlling geodynamic processes. There is few information regarding heat flow values on Scotia arc. These values are mainly located in its westernmost, southern and easternmost part, which are not enough to extract conclusions regarding lithospheric thickness variations and asthenospheric flow. Taking advantage of the World Digital Magnetic Anomaly Map Project's compilation we have extracted magnetic anomaly data which fall inside the Scotia Arc and surrounding areas. This magnetic anomaly picture provides the best representation of magnetic properties to date. We propose to use spectral methods on this regional magnetic compilation to obtain depth to the bottom of magnetic sources as a proxy to infer Curie depth and heat flow distribution in the Scotia Sea.

    Maria Skłodowska-Curie--a Nobel Prize winner in chemistry--the elements of learning of chemistry gained just by a dint of work of more than ten months in Warsaw in the Institute of Industry and Agriculture Museum. The Nobel Prize concerned a contribution to the progress of chemistry through the discovery of radium and polonium, separation of radium and study of properties of this amazing element. It was awarded for an extremely arduous work, during which the chemical reactions being the principles of analytical chemistry were realized. Unlike to a typical analytical procedure, an initial attempt here was the thousands of kilograms of uranium ore: pitchblende. The final effect was small amounts of new elements: polonium and radium. Both the knowledge and the intuition of the researcher let her have a triumph. The difficulties she experienced because the properties of the searched chemical elements could only be evaluated thanks to the knowledge on other chemical elements. A significant achievement was the determination of the samples by means of radioactivity measurement, which gave rise to radiochemical analytical methods. An extreme analytical precision was demanded in multiple processes of fractional crystallization and precipitation which finally led to the calculation of the atomic mass of radium.

    2015-12-01

    Barium ferrite has attracted considerable interest in the fields of permanent magnets and perpendicular magnetic recording due to its strong uniaxial anisotropy and high Curie temperature (Tc). We prepared aluminum doped barium ferrite ceramics (BaAlxFe12-xO19, 0≤x≤6) by the ball mill method. The powder was milled for 96 h, and after forming pellets, annealed for 48 h in air at 1000 °C. The X-ray diffraction (XRD) data show that there are only single hexagonal phases in the samples without any impurity phase. The crystal lattice constants, a and c, were calculated by Cohen's method. Both a and c decrease with increasing x, ranging from 0.588 nm and 2.318 nm to 0.573 nm and 2.294 nm, respectively. A Vibrating Sample Magnetometer (VSM) and Superconducting Quantum Interference Device (SQUID) were used to investigate Tc and magnetic properties of BaFe12-xAlxO19. It is found that Tc decreases with increasing x, from 425 °C to 298 °C. It is also found that the saturated magnetization (4πMs) decreases with increasing x, while the coercivity (Hc) increases with the increase in x. The anisotropy field was also determined from the SQUID measurement.

  9. Cluster Mott insulators and two Curie-Weiss regimes on an anisotropic kagome lattice

    2016-06-01

    Motivated by recent experiments on the quantum-spin-liquid candidate material LiZn2Mo3O8 , we study a single-band extended Hubbard model on an anisotropic kagome lattice with the 1/6 electron filling. Due to the partial filling of the lattice, the intersite repulsive interaction is necessary to generate Mott insulators, where electrons are localized in clusters rather than at lattice sites. It is shown that these cluster Mott insulators are generally U(1) quantum spin liquids with spinon Fermi surfaces. The nature of charge excitations in cluster Mott insulators can be quite different from conventional Mott insulator and we show that there exists a cluster Mott insulator where charge fluctuations around the hexagonal cluster induce a plaquette charge order (PCO). The spinon excitation spectrum in this spin-liquid cluster Mott insulator is reconstructed due to the PCO so that only 1/3 of the total spinon excitations are magnetically active. Based on these results, we propose that the two Curie-Weiss regimes of the spin susceptibility in LiZn2Mo3O8 may be explained by finite-temperature properties of the cluster Mott insulator with the PCO as well as fractionalized spinon excitations. Existing and possible future experiments on LiZn2Mo3O8 , and other Mo-based cluster magnets are discussed in light of these theoretical predictions.

    The realization and application of spintronic devices would be dramatically advanced if room-temperature ferromagnetism could be integrated into semiconductor nanostructures, especially when compatible with mature silicon technology. Herein, we report the observation of such a system - an Si/MnGe superlattice with quantum dots well aligned in the vertical direction successfully grown by molecular beam epitaxy. Such a unique system could take full advantage of the type-II energy band structure of the Si/Ge heterostructure, which could trap the holes inside MnGe QDs, significantly enhancing the hole-mediated ferromagnetism. Magnetic measurements indeed found that the superlattice structure exhibited a Curie temperature of above 400 K. Furthermore, zero-field cooling and field cooling curves could confirm the absence of ferromagnetic compounds, such as Ge8Mn11 (Tc ∼ 270 K) and Ge3Mn5 (Tc ∼ 296 K) in our system. Magnetotransport measurement revealed a clear magnetoresistance transition from negative to positive and a pronounced anomalous Hall effect. Such a unique Si/MnGe superlattice sets a new stage for strengthening ferromagnetism due to the enhanced hole-mediation by quantum confinement, which can be exploited for realizing the room-temperature Ge-based spin field-effect transistors in the future.

    End goal of translational medicine is to combine disciplines and expertise to eventually promote improvement of the global healthcare system by delivering effective therapies to individuals and society. Well-trained experts of the translational medicine process endowed with profound knowledge of biomedical technology, ethical and clinical issues, as well as leadership and teamwork abilities are essential for the effective development of tangible therapeutic products for patients. In this article we focus on education and, in particular, we discuss how programs providing training on the broad spectrum of the translational medicine continuum have still a limited degree of diffusion and do not provide professional support and mentorship in the long-term, resulting in the lack of well established professionals of translational medicine (TMPs) in the scientific community. Here, we describe the Marie Skłodowska-Curie Actions program ITN-EUtrain (EUropean Translational tRaining for Autoimmunity & Immune manipulation Network) where training on the Translational Medicine machinery was integrated with education on professional and personal skills, mentoring, and a long-lasting network of TMPs.

    The Marie Curie Cancer Care (2003) Spiritual and Religious Care Competencies for Specialist Palliative Care provide a common language for healthcare practitioners in the nebulous area of spiritual care. The development of a pilot blended learning event, as described in this paper, sought to integrate the competencies into practice by providing opportunities both online and in the classroom to explore this aspect of holistic care in depth. In the planning stages, multiprofessional focus groups determined the level of delivery, and emerging themes shaped the content. Self-awareness and reflection were key features and part of the overall process to improve competency. The features of the virtual learning environment (VLE) used were video, facilitated asynchronous discussion and direct links to key articles and documents, while interactive classroom activities built on prior learning. Evaluation covered all aspects of the course design from participant and facilitator perspectives. Participant comments were overwhelmingly positive in relation to the content and chosen delivery methods with concerns about online learning proving unfounded.

  13. Ab initio theory of exchange interactions and the Curie temperature of bulk Gd

    Turek, I; Bihlmayer, G; Bluegel, S

    2003-01-01

    An ab initio approach to the magnetic properties of bulk hexagonal Gd is developed that is based on the local spin-density approximation with the 4f electrons treated as localized core electrons. The effective one-electron problem is solved using the tight-binding linear muffin-tin orbital method in the atomic-sphere approximation with the valence basis consisting of s-, p-and d-type orbitals. The approach leads to a correct description of the ground-state properties like the stability of the ferromagnetic structure, the magnetic moment and the equilibrium lattice constant. Application of a real-space Green-function formalism yields the exchange pair interactions between distant neighbours that are inevitable for quantitative studies of magnetic excitations. The distance dependence and anisotropy of the exchange pair interactions are presented and the Curie temperature in the mean-field approximation is evaluated. The obtained value of 334 K is in much better agreement with the experimental value of 293 K tha...

    2017-01-01

    Emergency medicine (EM) fellowships are becoming increasingly numerous, and there is a growing trend among EM residents to pursue postgraduate fellowship training. Scant data have been published on the prevalence of postgraduate training among emergency physicians. We aimed to describe the prevalence and regional variation of fellowships among EM residency leadership. We conducted an online anonymous survey that was sent to the Council of EM Residency Directors (CORD) membership in October 2014. The survey was a brief questionnaire, which inquired about fellowship, secondary board certification, gender, and length in a leadership position of each member of its residency leadership. We separated the responses to the survey into four different geographic regions. The geographic regions were defined by the same classification used by the National Resident Matching Program (NRMP). We defined residency leadership as program director (PD), associate PD and assistant PD. Residencies that did not complete the survey were then individually contacted to encourage completion. The survey was initially piloted for ease of use and understanding of the questions with a select few EM PDs. We obtained responses from 145 of the 164 Accrediting Council for Graduate Medical Education-accredited EM residencies (88%). The fellowship prevalence among PDs, associate PDs, and assistant PDs was 21.4%, 20.3%, and 24.9% respectively. The most common fellowship completed was a fellowship in toxicology. Secondary board certification among PDs, associate PDs, and assistant PDs was 9.7%, 4.8%, and 2.9% respectively. Eighty-two percent of PDs have at least five years in residency leadership. Seventy-six percent of PDs were male, and there was a near-even split of gender among associate PDs and assistant PDs. The Western region had the highest percentage of fellowship and or secondary board certification among all levels of residency leadership. There is a low prevalence of fellowship training and

  15. Pathology informatics fellowship training: Focus on molecular pathology

    2014-01-01

    Full Text Available Background: Pathology informatics is both emerging as a distinct subspecialty and simultaneously becoming deeply integrated within the breadth of pathology practice. As specialists, pathology informaticians need a broad skill set, including aptitude with information fundamentals, information systems, workflow and process, and governance and management. Currently, many of those seeking training in pathology informatics additionally choose training in a second subspecialty. Combining pathology informatics training with molecular pathology is a natural extension, as molecular pathology is a subspecialty with high potential for application of modern biomedical informatics techniques. Methods and Results: Pathology informatics and molecular pathology fellows and faculty evaluated the current fellowship program′s core curriculum topics and subtopics for relevance to molecular pathology. By focusing on the overlap between the two disciplines, a structured curriculum consisting of didactics, operational rotations, and research projects was developed for those fellows interested in both pathology informatics and molecular pathology. Conclusions: The scope of molecular diagnostics is expanding dramatically as technology advances and our understanding of disease extends to the genetic level. Here, we highlight many of the informatics challenges facing molecular pathology today, and outline specific informatics principles necessary for the training of future molecular pathologists.

    2011-01-01

    Background There has been an increasing role of advanced minimally invasive procedures in hepatopancreatobilliary (HPB) surgery. However, there are no set minimum laparoscopic case requirements. Methods A 14-question electronic survey was sent to 82 worldwide HPB fellowship programme directors. Results Forty-nine per cent (n = 40) of the programme directors responded. The programmes were predominantly university based (83%). Programmes had either one (55%) or two fellows (40%) each year. Programmes (35–48%) had average annual volumes of 51–100 hepatic, 51–100 pancreatic and 25–50 biliary cases. For many programmes, <10% of hepatic (48%), pancreatic (40%) and biliary (70%) cases were done laparoscopically. The average annual fellow case volumes for hepatic, pancreatic and biliary surgeries were 25–50 (62%), 25–50 (47%) and <25 (50%), respectively. The average annual number of hepatic, pancreatic and biliary cases done laparoscopically by a fellow was 9, 9 and 4, which constitutes 36%, 36% and 16%, respectively, of the International Hepato-Pancreato-Billiary Association (IHPBA) requirement. Conclusion We surmise that the low average number of surgeries performed by minimally-invasive techniques by HPB fellows is not sufficient in today's practice. Should there be an increase in the minimal number of hepatic, pancreatic and complex biliary cases to 50, 50, and 25, with at least 50% of these performed laparoscopically? PMID:21309929

    Gender disparities in the fields of science, technology, engineering and mathematics, including the geosciences, are well documented and widely discussed. In the geosciences, despite receiving 40% of doctoral degrees, women hold less than 10% of full professorial positions. A significant leak in the pipeline occurs during postdoctoral years, so biases embedded in postdoctoral processes, such as biases in recommendation letters, may be deterrents to careers in geoscience for women. Here we present an analysis of an international data set of 1,224 recommendation letters, submitted by recommenders from 54 countries, for postdoctoral fellowships in the geosciences over the period 2007-2012. We examine the relationship between applicant gender and two outcomes of interest: letter length and letter tone. Our results reveal that female applicants are only half as likely to receive excellent letters versus good letters compared to male applicants. We also find no evidence that male and female recommenders differ in their likelihood to write stronger letters for male applicants over female applicants. Our analysis also reveals significant regional differences in letter length, with letters from the Americas being significantly longer than any other region, whereas letter tone appears to be distributed equivalently across all world regions. These results suggest that women are significantly less likely to receive excellent recommendation letters than their male counterparts at a critical juncture in their career.

    The New Horizons Educator Fellowship Program (NHEFP), originally based on the MESSENGER Fellows Program, is a public outreach initiative for motivated volunteers across the nation. These volunteers are master teachers who communicate the excitement of NASA's New Horizons mission to Pluto and information about recent discoveries to teachers, students, and people in their local communities. Many of the Fellows utilize their experiences and knowledge as members of other programs such as MESSENGER Fellows, Heliophysics Educator Ambassadors, Solar System Educators and Ambassadors to promote the mission thorough professional development workshops incorporating themes, activities, and recent discoveries with other NASA programs to present a well-rounded view of our Solar System. Unlike teacher-volunteer programs tied to missions that take place closer to Earth, the time between New Horizons' launch and its closest approach to Pluto is 9.5 years, with the spacecraft in hibernation for most of its voyager. NHEFP has maintained a core group of Fellows who, through periodic face-to-face or remote training, have taken advantage of opportunities for networking, sharing of ideas in best practices, activities, and presenting and keeping audiences interested in the mission during its long journey to Pluto. This involvement has been key to the program's success.

    The primary objective of this project is to stimulate academic interest in the conventional hydropower field by supplying research support for at least eight individual Master of Science (MS) or Doctoral (PhD) level research projects, each consisting of a graduate student supervised by a faculty member. We have completed many of the individual student research projects: 2 PhD students have finished, and 4 are still working towards their PhD degree. 4 MS students have finished, and 2 are still working towards their MS degree, one of which is due to finish this April. In addition, 4 undergraduate student projects have been completed, and one is to be completed this April. These projects were supervised by 7 faculty members and an Advisory/Review Panel. Our students and faculty have presented their work at national or international conferences and have submitted several journal publications. Three of our graduate students (Keith Martin, Dan Leonard and Hosein Foroutan) have received HRF Fellowships during the course of this project. All of the remaining students are anticipated to be graduated by the end of Fall Semester 2014. All of the tasks for this project will have been completed once all the students have been graduated, although it will be another year or two until all the journal publications have been finalized based on the work performed as part of this DOE Hydropower project.

    Congressional Earmark Funding was used to create a Postdoctoral Environmental Fellowship Program, interdisciplinary Environmental Working Groups, and special initiatives to create a dialogue around the environment at the University of Massachusetts Amherst to mobilize faculty to work together to respond to emerging environmental needs and to build institutional capacity to launch programmatic environmental activities across campus over time. Developing these networks of expertise will enable the University to more effectively and swiftly respond to emerging environmental needs and assume a leadership role in varied environmental fields. Over the course of the project 20 proposals were submitted to a variety of funding agencies involving faculty teams from 19 academic departments; 4 projects were awarded totaling $950,000; special events were organized including the Environmental Lecture Series which attracted more than 1,000 attendees over the course of the project; 75 University faculty became involved in one or more Working Groups (original three Working Groups plus Phase 2 Working Groups); an expertise database was developed with approximately 275 faculty involved in environmental research and education as part of a campus-wide network of environmental expertise; 12 University centers and partners participated; and the three Environmental Fellows produced 3 publications as well as a number of presentations and papers in progress.

    The Benjamin H. Kean Fellowship in Tropical Medicine is an American Society of Tropical Medicine and Hygiene initiative that provides medical students with funding for international clinical or research experiences lasting at least 1 month. Of the 175 Kean fellows from 1998 to 2013, 140 had current available e-mails, and 70 of the 140 (50%) responded to a survey about their fellowship experience. Alumni indicated that the Kean Fellowship had a high impact on their career plans with regard to preparation for (N = 65, 94.2%) and inspiration to pursue (N = 59, 88.1%) a career in tropical medicine and global health. Continued involvement in tropical medicine and global health was common: 52 alumni (74.3%) were currently working in tropical medicine or global health, 49 (71.0%) had done so in the interim between the Kean fellowship and their current position; and 17 of 19 Kean fellows (89.4%) who had completed all medical training and were now in professional practice continued to work in tropical medicine and global health. Alumni had been highly productive academically, publishing a total of 831 PubMed-indexed manuscripts, almost all on tropical medicine or global health topics, in the period between their fellowship year and 2013. Alumni reported strengths of the fellowship including funding, networking, and flexibility, and suggested that more networking and career mentoring would enhance the program. The Benjamin H. Kean fellowship program has been highly successful at inspiring and fostering ongoing work by trainees in tropical medicine and global health.

    We have successfully grown nanoscale Fe2CrAl thin films on polished Si/SiO2 substrates using an ultra-high vacuum deposition with a base pressure of 9×10-10 Torr. The thickness of thin films ranges from 30 to 100 nm. These films exhibit cubic crystal structure with lattice disorder and display ferromagnetic behavior. The Curie temperature is greater than 400 K, which is much higher than that reported for bulk Fe2CrAl. The magnetic moments of the films varies from 2.5 to 2.8 μB per formula unit, which is larger than the reported bulk values. Thus, the disordered nanoscale Fe2CrAl films exhibit strong Fe-Fe exchange interactions through Fe-Cr-Fe and Fe-Al-Fe layers, resulting in both a large magnetization and a high Curie temperature.

    Effect of pressure on the Curie temperature TC of the Mn-rich Heusler alloys Mn2RuSn and Mn2PdSn has been investigated by measuring the temperature dependence of initial permeability at various pressures up to 10 kbar. It was found that the Curie temperatures of Mn2RuSn and Mn2PdSn decrease with increasing pressure. The pressure derivatives of TC were estimated to be -0.59 K/kbar for Mn2RuSn and -0.80 K/kbar for Mn2PdSn. On the basis of the experimental results, the relationship between the magnetic transition temperature and the Mn-Mn distance is discussed.

    The Dipartimento di Fisica Sperimentale and the Istituto Nazionale di Fisica Nucleare (INFN), Torino, in collaboration with the Institut Curie-Centre de Protontherapie de Orsay (CPO), have developed and built a pixel parallel plate ionization chamber to be used as monitor for the proton therapy beam line at the Institut Curie-CPO (Orsay, France). The sensitive area of the detector is (160x160) mm{sup 2}, with the anode segmented in 1024 square pixels arranged in a 32x32 matrix; the area of each pixel is (5x5) mm{sup 2}. The detector has been placed on the beam line just upstream of the last collimator to monitor the beam shape and to measure the stability and reproducibility of the delivery system. In this paper, we present a detailed description of the detector and the results of a set of preliminary tests.

    Using aeromagnetic data acquired in the area from the Cerro Prieto geothermal field, we estimated the depth to the Curie point isotherm, interpreted as the base of the magnetic sources, following statistical spectral-based techniques. According to our results the Curie point isotherm is located at a depths ranging from 14 to 17 km. Our result is somewhat deeper than that obtained previously based only in 2-D and 3-D forward modeling of previous low-quality data. However, our results are supported by independent information comprising geothermal gradients, seismicity distribution in the crust, and gravity determined crustal thickness. Our results imply a high thermal gradient (ranging between 33 and 38 °C/km) and high heat flow (of about 100 mW/m 2) for the study area. The thermal regime for the area is inferred to be similar to that from the Salton trough.

    2010-07-01

    Recent measurements of GaMnAs alloy samples with a very small content of P atoms prepared by ion-implanted pulsed laser melting (II-PLM) [Phys. Rev. Lett. 101, 087203 (2008)10.1103/PhysRevLett.101.087203] have shown surprisingly low Curie temperature as compared to undoped samples. An explanation based on a possible metal-insulator transition at constant Mn doping was proposed based on a dramatic increase of the sample resistivity. However, no quantitative calculations supporting such a picture as concerns the Curie temperature were shown. We will present a parameter-free theory of the Curie temperature (TC) which assumes that possible defects due to the II-PLM such as, e.g., space inhomogeneities, vacancies, clustering, and also conventional compensating defects will reduce the sample hole concentration. Their effect was first qualitatively modeled in the framework of the rigid-band model by adjusting the system Fermi level due to the reduction of the carrier concentration which is considered as a parameter of the theory. In addition, the effect of possible conventional compensating defects, such as, e.g., As and P antisites or P and Mn interstitials was also investigated. TC ’s are calculated within the self-consistent local RPA (SCLRPA) and Monte Carlo (MC) simulations. We will demonstrate that a reasonable agreement of calculated and measured TC can be obtained for reduced hole concentrations which are known to exist in GaMnAs samples. As concerns possible specific defects, we have shown that P and Mn interstitials are particularly effective in the reduction of the sample Curie temperature.

To avoid local overheating, perovskite NPs with a lower Curie temperature (Tc were proposed for use in thermotherapy. However, deposited power decreases when approaching the Curie temperature and consequently may not be sufficient for effective ablation. The goal of the study was to test this hypothesis. Methods: Perovskite NPs (Tc =66°C–74°C were characterized and tested both in vitro and in vivo. In vitro, the cells suspended with NPs were exposed to a HF magnetic field together with control samples. In vivo, a NP suspension was injected into a induced tumor in rats. Distribution was checked by MRI and the rats were exposed to a HF field together with control animals. Apoptosis in the tissue was evaluated. Results and discussion: In vitro, the high concentration of suspended NPs caused an increase of the temperature in the cell sample, leading to cell death. In vivo, MRI confirmed distribution of the NPs in the tumor. The temperature in the tumor with injected NPs did not increase

    The magnetic properties of epitaxial Fe films on GaAs in the range of the first few monolayers have been the subject of a considerable number of investigations in recent years. The absence of magnetic signatures at room temperature has been attributed to the existence of a magnetic 'dead' layer as well as superparamagnetism. By examining the temperature dependence of the magnetic linear dichroism of the Fe core level photoelectrons, we found a ferromagnetic regime with a Curie temperature, T {sub c} substantially lower than room temperature, e.g., a T {sub c} of about 240 K for thin films of a nominal thickness of 0.9 nm. The values of Curie temperature were sensitive to the initial GaAs substrate conditions and the thickness of the Fe over-layer with a layer of thickness of 1.25 nm showing a T {sub c} above room temperature. The data suggest that the thin Fe films on GaAs(0 0 1) may have ferromagnetic character at an earlier stage of growth than previously expected, although a weaker exchange interaction in the films leads to a substantial reduction in Curie temperature.

For 24,897 proposals evaluated from 2007 to 2013, the association between average IER and CR scores was very high across different panels, grant calls and years. Median average deviation (AD index, used as a measure of inter-rater agreement, was 5.4 points on a 0-100 scale (interquartile range 3.4-8.3, overall, demonstrating a good general agreement among raters. For proposals where one rater disagreed with the other two raters (n=1424; 5.7%, or where all 3 raters disagreed (n=2075; 8.3%, the average IER and CR scores were still highly associated. Disagreement was more frequent for proposals from Economics/Social Sciences and Humanities panels. Greater disagreement was observed for proposals with lower average IER scores. CR scores for proposals with initial disagreement were also significantly lower. Proposals with a large absolute difference between the average IER and CR scores (≥10 points; n=368, 1.5% generally had lower CR scores. An inter-correlation matrix of individual raters' scores of evaluation criteria of proposals indicated that these scores were, in general, a reflection of raters' overall scores. Our analysis demonstrated a good internal consistency and general high agreement among raters. Consensus meetings appear to be relevant for particular panels and subsets of proposals with large differences among raters' scores.

  15. Curie Temperature and Microstructural Changes Due to the Heating Treatment of Magnetic Amorphous Materials

    Full Text Available Three distinct alloys: Fe86Zr7Nb1Cu1B5, Fe82Zr7Nb2Cu1B8, and Fe81Pt5Zr7Nb1Cu1B5 were characterized both magnetically and structurally. The samples, obtained with spinning roller method as a ribbons 3 mm in width and 20 μm thick, were investigated as-quenched and after each step of a multi steps heating treatment procedure. Each sample was annealed at four steps, fifteen minutes at every temperature, starting from 573K+600K up to +700K depending on type of alloy. Mössbauer spectroscopy data and transmission electron microscope (HRE M pictures confirmed that the as-quenched samples are fully amorphous. This is not changed after the first stages of treatment heating leads to a reduction of free volumes. The heating treatment has a great influence on the magnetic susceptibilities. The treatment up to 600K improves soft magnetic properties: an χ increase was observed, from about 400 to almost 1000 for the samples of alloys without Pt, and from about 200 to 450 at maximum, for the Fe81Pt5Zr7Nb1Cu1B5. Further heating, at more elevated temperatures, leads to magnetic hardening of the samples. Curie temperatures, established from the location of Hopkinson’s maxima on the χ(T curve are in very good agreement with those obtained from the data of specific magnetization, σ(T, measured in a field of 0.75T. As a critical parameter β was chosen to be equal 0.36 for these calculations, it confirmed that the alloys may be considered as ferromagnetic of Heisenberg type. Heating treatment resulted in decreasing of TC. These changes are within a range of several K.

    GLANAM (Glaciated North Atlantic Margins) is an Initial Training Network (ITN) funded under the EU Marie Curie Programme. It comprises 10 research partners from Norway, UK and Denmark, including 7 University research teams, 1 industrial full partner and 2 industrial associate partners. The GLANAM network will employ and train 15 early career researchers (Fellows). The aim of GLANAM is to improve the career prospects and development of young researchers in both the public and private sector within the field of earth science, focusing on North Atlantic glaciated margins. The young scientists will perform multi-disciplinary research and receive training in geophysics, remote sensing, GIS, sedimentology, geomorphology, stratigraphy, geochemistry and numerical modeling through three interconnected work packages that collectively address knowledge gaps related to the large, glacial age, sedimentary depocentres on the North Atlantic margin. The 15 Fellows will work on projects that geographically extend from Ireland in the south to the High Arctic. Filling these gaps will not only result in major new insights regarding glacial age processes on continental margins in general, but will also provide paleoclimate information essential for understanding the role of marine-based ice sheets in the climate system and for the testing of climate models. GLANAM brings together leading European research groups working on glaciated margins in a coordinated and collaborative research and training project. Focusing on the North Atlantic margins, this coordinated approach will lead to a major advance in the understanding of glaciated margins more widely and will fundamentally strengthen European research and build capacity in this field.

    From 1 January 1951 to 30 June 1998, 696 patients presented spontaneously or were referred to the French Institut Curie Radiopathology Unit following a more or less severe accidental irradiation. Of these, 568 patients came from France, while 128 were sent by various foreign countries. The very great majority of irradiation accidents occurred in the workplace, particularly in industry. Interestingly, 'non-nuclear' industry was responsible for three times more events than the nuclear industry. While incidental irradiation of the public by lost radioactive sources was exceedingly rare in France, it seemed to be more frequent in our cohort of foreign patients. Radiation phobia accounted for about 10% of cases in the French cohort, but the number of cases did not seem to increase with time. Overall, the accrual of patients over time appears to be stable, with 10 to 25 new cases consulting each year. Fortunately, a majority of cases corresponded to low-level irradiation (and even no irradiation at all). In the French cohort, only 21.6% of patients, showing deterministic effects, required some form of treatment, with 4.9% considered as 'severe' cases. Not unexpectedly, more patients required treatment in the foreign cohort (35.2%), with 24.2% of severe cases, including four deaths. The main features of this database are consistent with the data previously reported by the IAEA, UNSCEAR and REAC/TS. Although the number of severe cases is small, it should still be considered to be too high, especially as most of these accidents could have been easily avoided if a few basic radioprotection rules had been fully respected.

    We have estimated the Curie Point Depth (CPD) using the average radial power spectrum in a tectonically complex area located in the SW Caribbean basin. Data analyzed came from the World Digital Magnetic Anomaly Map, and three methods have been used to compare results and evaluate uncertainties: Centroid, Spectral Peak, and Forward Modeling. Results show a match along the three methods, suggesting that the CPD values in the area ranging between 6 km and 50 km. The results share the following characteristics: A) High values (> 30 km) are in continental regions; B) There is a trend of maximum CPD values along the SW-NE direction, starting from the Central Cordillera in Colombia to the Maracaibo Lake in Venezuela; C) There is a maximum CPD at the Sierra Nevada de Santa Marta (Colombia) as well as between Costa Rica - Nicaragua and Nicaragua - Honduras borders. The lowest CPD values (coastal regions and offshore. We also tested results by estimating the geothermal gradient and comparing measured observations of the study area. Our results suggest at least five thermal terrains in the SW Caribbean Basin: A) The area that is comprising the Venezuela Basin, the Beata Ridge and the Colombia Basin up to longitude parallel to the Providencia Throat. B) The area that includes zones to the north of the Cocos Ridge and Panam Basin up to the trench. C) The orogenic region of the northern Andes and including areas of the Santa Marta Massif. D) The continental sector that encompasses Nicaragua, northern Costa Rica and eastern of Honduras. E) Corresponds to areas of the northern Venezuela and Colombia, NW of Colombia, the Panamanian territory and the transition zones between the Upper and Lower Nicaragua Rise.

    This is the administrative report for the 2004 NASA Faculty Fellowship Program (NFFP) held at the George C. Marshall Space Flight Center (MSFC) for the 40th consecutive year. The NFFP offers science and engineering faculty at U.S. colleges and universities hands-on exposure to NASA s research challenges through summer research residencies and extended research opportunities at participating NASA research Centers. During this program, fellows work closely with NASA colleagues on research challenges important to NASA's strategic enterprises that are of mutual interest to the fellow and the Center. The nominal starting and .nishing dates for the 10-week program were June 1 through August 6, 2004. The program was sponsored by NASA Headquarters, Washington, DC, and operated under contract by The University of Alabama, The University of Alabama in Huntsville, and Alabama A&M University. In addition, promotion and applications are managed by the American Society for Engineering Education (ASEE) and assessment is completed by Universities Space Research Association (USRA). The primary objectives of the NFFP are to: Increase the quality and quantity of research collaborations between NASA and the academic community that contribute to the Agency s space aeronautics and space science mission. Engage faculty from colleges, universities, and community colleges in current NASA research and development. Foster a greater public awareness of NASA science and technology, and therefore facilitate academic and workforce literacy in these areas. Strengthen faculty capabilities to enhance the STEM workforce, advance competition, and infuse mission-related research and technology content into classroom teaching. Increase participation of underrepresented and underserved faculty and institutions in NASA science and technology.

    The COSPAR Capacity Building Workshops have been conceived to meet the following objec-tives: i) to increase knowledge and use of public archives of space data in order both to broaden the scope of research programmes in developing countries and also to ensure that scientists in those countries are aware of the full range of facilities that are available to them, ii) to provide highly-practical instruction in the use of these archives and the associated publicly-available software, and iii) to foster personal links between participants and experienced scientists at-tending the workshops to contribute to reducing the isolation often experienced by scientists in developing countries. Since 2001 a total of eleven workshops have been successfully held in different scientific areas (X-ray, Gamma-ray and Space Optical and UV Astronomy, Mag-netospheric Physics, Space Oceanography and Planetary Science) in nine developing countries (Brazil, India, China, South Africa, Morocco, Romania, Uruguay, Egypt and Malaysia). To enable young scientists who have participated in a Workshop to build on skills gained there, the COSPAR Panel for Capacity-Building has initiated in 2008 an associated Fellowship Programme. A total number of 14 institutes from several european countries, USA, China and India are participating in the programme offering those to carry out a 2-4 week research project together with a resident scientist. We will discuss the modalities of the workshops, the so-far gained experience, and the future including collaborations with other institutions sharing the aim of increasing the scientific activities in developing countries.

    Background Hepato-pancreato-biliary (HPB) fellowships in North America are difficult to secure with an acceptance rate of 1 in 3 applicants. Desirable characteristics in an HPB surgery applicant have not been previously reported. This study examines the perceptions of trainees and HPB program directors with regards to positive attributes in applicants for HPB fellowships. Methods Parallel surveys were distributed by email with a web-link to current and recent HPB fellows in North America (from the past 5 years) with questions addressing the following domains: surgical training, research experience, and mentorship. A similar survey was distributed to HPB fellowship program directors in North America requesting their opinion as to the importance of these characteristics in potential applicants. Results 32 of 60 of surveyed fellows and 21 of 38 of surveyed program directors responded between November 2014–February 2015. Fellows overall came from fairly diverse backgrounds (13/32 were overseas medical graduates) about one third of respondents having had some prior research experience. Program directors gave priority to the applicant's interview, curriculum vitae, and their recommendation letters (in order of importance). Both the surveyed fellows and program directors felt that the characteristics most important in a successful HPB fellowship candidate include interpersonal skills, perceived operative skills, and perceived fund of knowledge. Conclusion Results of this survey provide useful and practical information for trainees considering applying to an HPB fellowship program. PMID:27154813

    At the American Society for Microbiology (ASM), fellowships are a key means of providing immersive research opportunities for the student sector. To assess the impact of ASM student activities and inform their planning, the Society commissioned a study of two long-standing initiatives in 2015, namely the ASM Undergraduate Research Fellowship (URF), established in 1993, and the ASM Robert D. Watkins Graduate Research Fellowship (Watkins) Program, established in 1980. A mixed-methods approach was used to collect data about the participants' fellowship experience, track educational and employment status, and determine program impacts from 325 individuals (223 URF and 73 Watkins fellows). Challenges presented by the study include the fact that inherent in fellowships is the provision of financial support that affords participants opportunities that might otherwise be unavailable to them. As a result, participant feelings of indebtedness to the Society may have introduced biased study responses. In addition, some respondents were asked to reflect on experiences from 20 to 30 years ago-a lapse in time that may have challenged their memories. Based on measures such as enrollment in or completion of advanced degree programs, employment in science, and publication and presentation history, project participants show evidence of accomplishment. Participants also reported gains in affective behaviors such as confidence and belonging.

    Formal training in health care quality and safety has become an important component of medical education at all levels, and quality and safety are core concepts within the practice-based learning and system-based practice medical education competencies. Residency and fellowship programs are rapidly attempting to incorporate quality and safety curriculum into their training programs but have encountered numerous challenges and barriers. Many program directors have questioned the feasibility and utility of quality and safety education during this stage of training. In 2010, we adopted a quality and safety educational module in our neonatal fellowship program that sought to provide a robust and practical introduction to quality improvement and patient safety through a combination of didactic and experiential activities. Our module has been successfully integrated into the fellowship program's curriculum and has been beneficial to trainees, faculty, and our clinical services, and our experience suggests that fellowship may be particularly well suited to incorporation of quality and safety training. We describe our module and share tools and lessons learned during our experience; we believe these resources will be useful to other fellowship programs seeking to improve the quality and safety education of their trainees.

    Robotic technology has transformed both practice and education in many adult surgical specialties; no standardized training guidelines in pediatric surgery currently exist. The purpose of our study was to assess the prevalence of robotic procedures and extent of robotic surgery education in US pediatric surgery fellowships. A deidentified survey measured utilization of the robot, perception on the utility of the robot, and its incorporation in training among the program directors of Accreditation Council for Graduate Medical Education (ACGME) pediatric surgery fellowships in the United States. Forty-one of the 47 fellowship programs (87%) responded to the survey. While 67% of respondents indicated the presence of a robot in their facility, only 26% reported its utilizing in their surgical practice. Among programs not utilizing the robot, most common reasons provided were lack of clear supportive evidence, increased intraoperative time, and incompatibility of instrument size to pediatric patients. While 58% of program directors believe that there is a future role for robotic surgery in children, only 18% indicated that robotic training should play a part in pediatric surgery education. Consequently, while over 66% of survey respondents received training in robot-assisted surgical technique, only 29% of fellows receive robot-assisted training during their fellowship. A majority of fellowships have access to a robot, but few utilize the technology in their current practice or as part of training. Further investigation is required into both the technology's potential benefits in the pediatric population and its role in pediatric surgery training.

    Stanford Biodesign launched its Innovation Fellowship in 2001 as a first-of-its kind postgraduate training experience for teaching biomedical technology innovators a need-driven process for developing medical technologies and delivering them to patients. Since then, many design-oriented educational programs have been initiated, yet the impact of this type of training remains poorly understood. This study measures the career focus, leadership trajectory, and productivity of 114 Biodesign Innovation Fellowship alumni based on survey data and public career information. It also compares alumni on certain publicly available metrics to finalists interviewed but not selected. Overall, 60% of alumni are employed in health technology in contrast to 35% of finalists interviewed but not selected. On leadership, 72% of alumni hold managerial or higher positions compared to 48% of the finalist group. A total of 67% of alumni reported that the fellowship had been "extremely beneficial" on their careers. As a measure of technology translation, more than 440,000 patients have been reached with technologies developed directly out of the Biodesign Innovation Fellowship, with another 1,000,000+ aided by solutions initiated by alumni after their training. This study suggests a positive impact of the fellowship program on the career focus, leadership, and productivity of its alumni.

    The American Orthopaedic Association-Japanese Orthopaedic Association (AOA-JOA) traveling fellowship was established in 1992 as a method for creating collaboration between the American and Japanese orthopaedic communities and providing a friendly exchange of current practices and scientific endeavors. The fellowship is designed to allow early-career orthopaedic surgeons the opportunity to participate in international travel and scholarship. This year's traveling fellows (Hassan Mir, Wakenda Tyler, Leo Kroonen, and Dan Zlotolow) all hail from different parts of the United States and have a variety of practice subspecialties. During the fellowship, the fellows were able to visit five academic centers that spanned the entire country of Japan as well as the JOA meeting in Kobe. The experience is one that contributed to the growth and development of each fellow's practices and depth of understanding of orthopaedic surgery.

    2012-01-01

    The purpose of this study was to determine the impact of the initiation of a pediatric surgery fellowship on general surgery resident operative volume at 1 major academic institution. Retrospective review of operative records obtained from the Accreditation Council for Graduate Medical Education (ACGME) general surgery resident and pediatric surgery fellow case logs. Data collected included number and type of pediatric index cases per year, number of total pediatric surgery cases per year, and number of total cases logged as primary surgeon to date. Vanderbilt University School of Medicine Department of Surgery, which has an accredited general surgery program, finishes 7 chief residents per year during the study period, and instituted a new pediatric surgery fellowship in 2007. Case logs submitted by third and fourth year general surgery residents and first and second year pediatric surgery fellows were studied. The number of pediatric attending surgeons, relative value units (RVUs), and hospital admissions increased from 2003 to 2011. The median number of pediatric index cases performed by a resident decreased after the onset of fellowship from 34 cases to 23.5 cases per year (p pediatric surgery rotation also decreased from 74 to 53 cases per year after onset of the fellowship (p surgery resident index and overall case volume in pediatric surgery. Although operative volume is only 1 measure of surgical educational value, these findings suggest that the addition of surgical fellowships affects the educational experience of general surgery residents. We recommend that residency programs establish goals and calculate any potential impact on general surgery resident case volume before initiating a new surgical fellowship.

    Residents seek postresidency fellowship training to increase competency with novel surgical techniques and augment their fund of knowledge. Research productivity is a vital component of advancement in academic urology. Our objectives were to use the h-index (an objective and readily available bibliometric that has been repeatedly shown to correlate with scholarly impact, funding procurement, and academic promotion in urology as well as other specialties) to determine whether any relationship exists between fellowship training and scholarly impact among academic urologists. Additional examination was performed to determine whether any differences in scholarly influence are present among practitioners in the major urologic subspecialties. Overall, 851 faculty members from 101 academic urology departments were organized by academic rank and fellowship completed. Research productivity was calculated using the h-index, calculated from the Scopus database. There was no statistical difference in h-index found between fellowship-trained and nonfellowship-trained academic urologists. The highest h-indices were seen among urologic oncologists (18.1 ± 0.95) and nonfellowship-trained urologists (14.62 ± 0.80). Nearly 70% of department chairs included in this analysis were urologic oncologists or general urologists. No difference in h-index existed between fellowship-trained and nonfellowship-trained urologists, although practitioners in the subspecialty cohorts with the highest research productivity (nonfellowship-trained and urologic oncologists) comprised 70% of department chairpersons. This relationship suggests that a strong research profile is highly valued during selection for academic promotion. Differences existed on further comparison by subspecialty. Fellowship training may represent another potential opportunity to introduce structured research experiences for trainees. © 2013 Published by Association of Program Directors in Surgery on behalf of Association of

    We sought to determine the attributes of successful and unsuccessful fellowship applicants of the American Board of Obstetrics and Gynecology Inc (ABOG)-approved fellowship programs and to identify salient differences between subspecialty applicants. Anonymous questionnaires were completed by obstetrics and gynecology fellowship applicants using a web-based survey after match day of 2012. Fellowship applicant practices were evaluated and included importance of prematch preparations, interview process, networking practices, and postmatch reflections. A total of 327 fellowship applicants applying to programs accredited by the ABOG were surveyed, and 200 completed the survey (61% response rate). A comparison between prematch educational preparations pursued by applicants showed that matched applicants were more likely to come from allopathic medical schools (94%), attain membership in Alpha Omega Alpha and/or Phi Beta Kappa (27%), and receive a letter of recommendation from a nationally known subspecialist (77%) than unmatched applicants (P = .03, .005, and .007, respectively). Applicants to reproductive endocrinology and infertility were more likely than female pelvic medicine and reconstructive surgery to be members of academic honor societies (P = .008). Research publication was common among matched subspecialist applicants, with over half publishing 1-3 peer-reviewed manuscripts prior to matching. Applicants to gynecologic oncology did more visiting electives than any other specialty applicants (P obstetrics and gynecology fellowship applicants have superior prematch preparations, strong letters of recommendation from leaders in their field of interest, and multiple research publications. These data will guide applicants to a critical self-analysis before deciding to apply. Copyright © 2014 Mosby, Inc. All rights reserved.

    Alliance for Climate Education educates young people on the science of climate change and empowers them to take action. Since 2009, ACE has educated over two million students and trained more than 4,000 young leaders. The ACE Action Fellowship is a yearlong training program that gives young people the knowledge, skills and confidence to be strong climate leaders. Here, we present the results of the first year of evaluation of the Fellowship program in the 2014-15 school year. Sixty high school students completed matched surveys before and after completing the program. Students were evaluated on skills learned, actions taken, confidence gained, civic engagement, and plans to continue action on climate in the future. Results show that the Fellowship increases young people's confidence: 52% of Fellows report an increase in confidence in leading a group of peers on a climate-related campaign. Fellows also gained leadership skills. More than half of Fellows say they improved in the areas of recruitment, interpersonal communication skills, campaign planning, and public speaking. 50% of Fellows reported an increase in their likelihood of seeking elected office when of age. The Fellowship positively influences young people's intent to study a climate, energy or sustainability-related field. 63% of Fellows identify as people of color. Notably, despite entering the Fellowship with significantly lower self-ratings than white students in experience and skill sets, young people of color reported greater improvement in the areas of public speaking (25% improvement vs. 6% improvement) and petitioning (27% improvement vs. 1% improvement). These results show that the ACE Fellowship gives young people tangible skills and confidence that puts them on a path of climate leadership. Further evaluation will be done to expand the dataset, but early indications show that these young people are poised to make valuable contributions and bring a much needed diverse youth perspective to the

  15. Curie's hypotheses concerning radioactivity and the origin of the elements

    Energy Technology Data Exchange (ETDEWEB)

    Kuroda, P.K.

    1999-09-01

    Pierre Curie gave two hypotheses at first; (1) It can be supposed that the radioactive substances borrow the energy, which they release, from an external radiation, and their radiation would then be a secondary radiation, (2) It can be supposed that the radioactive substances draw from themselves the energy which they release. The second hypothesis has shown the more fertile in explaining the properties of the radioactive substances. Consequently, the first hypothesis became more or less forgotten. It appears, however, the first hypothesis should play an important role in explaining the phenomena concerning the origin of the elements. The Oklo Phenomenon has demonstrated that a nuclear fire had once existed on our planet earth and formation of heavy elements was occurring in nature. The author pointed out that the difference in the isotopic compositions of xenon found in meteorites, lunar samples and in the earth's atmosphere can only be explained as due to the alterations of the isotropic compositions of xenon by combined effect of (a) mass-fractionation, (b) spallation, and (c) stellar temperature neutron-capture reactions. The strange xenon components are not isotopically pure substance. Instead, xenon-HL is a mixture of the {sup 244}Pu fission xenon and the xenon whose isotopic compositions is severely altered by a combined effect of the processes (a), (b) and (c) mentioned above. These results also indicate that C1 carbonaceous chondrites, which is generally as the most primitive sample of the solar system material, began to retain its xenon 5.1 billion years ago, when the plutonium to uranium ratio in the solar system was as high as almost 0.6 (atom/atom), while the C2 carbonaceous chondrite began to retain their xenon about 150 million years later and the ordinary chondrites and achondrite about 500 to 600 million years later. This means that the birth of the solar system began soon after the last supernova exploded about 5.1 billion years ago, and the

    The field of vascular anomalies presents diverse challenges in diagnosis and management. Although many lesions involve the head and neck, training in vascular anomalies is not universally included in otolaryngology residencies and pediatric otolaryngology (POTO) fellowships. To explore the education in, exposure to, and comfort level of otolaryngology trainees with vascular anomalies. A survey was distributed to 39 POTO fellows and 44 residents in postgraduate year 5 who matched into POTO fellowships from April 22 through June 16, 2014. Survey responses from trainees on exposure to, education on, and comfort with vascular anomalies. Forty-four residents in postgraduate year 5 who applied to POTO fellowships and 39 POTO fellows were emailed the survey. Fourteen respondents were unable to be contacted owing to lack of a current email address. Thirty-six of 69 residents and fellows (18 fellows and 18 residents [52%]) responded to the survey. Twenty-seven trainees (75%) reported no participation in a vascular anomalies clinic during residency; 6 of these 27 individuals (22%) trained at institutions with a vascular anomalies clinic but did not participate in the clinic, and 28 of the 36 respondents (78%) reported that they had less than adequate or no exposure to vascular anomalies in residency. Among POTO fellows, 11 of 17 (65%) did not participate in a vascular anomalies clinic during fellowship, even though 8 of the 11 had a vascular anomalies clinic at their fellowship program. During fellowship training, 12 of 18 fellows (67%) reported that they had adequate exposure to vascular anomalies. Only 20 respondents (56%) felt comfortable distinguishing among diagnoses of vascular anomalies, and only 4 residents (22%) and 9 fellows (50%) felt comfortable treating patients with vascular anomalies. All fellows believed that training in vascular anomalies was important in fellowship, and 100% of respondents indicated that increased exposure to diagnosis and management of

    Education leaders at the 2012 Academic Emergency Medicine Consensus Conference on education research proposed that dedicated postgraduate education scholarship fellowships (ESFs) might provide an effective model for developing future faculty as scholars. A formal needs assessment was performed to understand the training gap and inform the development of ESFs. A mixed-methods needs assessment was conducted of four emergency medicine national stakeholder groups in 2013: department chairs; faculty education/research leaders; existing education fellowship directors; and current education fellows/graduates. Descriptive statistics were reported for quantitative data. Qualitative data from semistructured interviews and free-text responses were analyzed using a thematic approach. Participants were 11/15 (73%) education fellowship directors, 13/20 (65%) fellows/graduates, 106/239 (44%) faculty education/research leaders, and a convenience sample of 26 department chairs. Department chairs expected new education faculty to design didactics (85%) and teach clinically (96%). Faculty education/research leaders thought new faculty were inadequately prepared for job tasks (83.7%) and that ESFs would improve the overall quality of education research (91.1%). Fellowship directors noted that ESFs provide skills, mentorship, and protected time for graduates to become productive academicians. Current fellows/graduates reported pursing an ESF to develop skills in teaching and research methodology. Stakeholder groups uniformly perceived a need for training in education theory, clinical teaching, and education research. These findings support dedicated, deliberate training in these areas. Establishment of a structure for scholarly pursuits prior to assuming a full-time position will effectively prepare new faculty. These findings may inform the development, implementation, and curricula of ESFs.

    We have succeeded in increasing up to 150 K the Curie temperature in the Fe{sub 64}N{sub 36}6 invar alloy by means of a severe mechanical treatment followed by a heating up to 1073 K. The invar behavior is still present as revealed by the combination of magnetic measurements with neutron and x-ray techniques under extreme conditions, such as high temperature and high pressure. The proposed explanation is based in a selective induced microstrain around the Fe atoms, which causes a slight increase in the Fe-Fe interatomic distances, thus reinforcing ferromagnetic interactions due to the strong magnetoelastic coupling in these invar compounds.

  3. Studies on the Relation between the Composition of Thermal Sensitive MnZn Ferrite and Curie Temperature

    Thermal sensitive MnZn ferrite is a kind of soft magnetic ferrite material with lower Curie temperature (Tc) and can be used to make many kinds of magnetic thermal sensitive sensors with high sensitivity. In this paper, the relation between the composition of thermal sensitive ferrite and Tc was studied. It was found that Tc changes linearly with ZnO extent when the content of Fe2O3 is fixed. Based on lots of experiments, an experimential formula to determine Tc was given out.

    2016-06-01

    A series of Ba1-x-ySrxCayTiO3 compounds were prepared with varying average ionic radii and cation disorder on A-site. All samples showed typical ferroelectric behavior. A simple empirical equation correlated Curie temperature, TC, with the values of ionic radii of A-site cations. This correlation was related to the distortion of TiO6 octahedra observed during neutron diffraction studies. The equation was used for the selection of compounds with predetermined values of TC. The effects of A-site ionic radii on the temperatures of phase transitions in Ba1-x-ySrxCayTiO3 were discussed.

    Many studies from various fields of medicine about the accuracy of residency and fellowship applications have reported disturbing percentages of candidates with publication misrepresentation on their applications. However, other similar studies have found much lower percentages. No evaluation of these types of studies is currently available to explain this disparity. Therefore, this study evaluated the wide range of percentages of applicants with publication misrepresentation reported in the literature. Studies of residency and fellowship applicant misrepresentation were identified and reviewed. Using uniform inclusion criteria, the data reported by each study were recalculated to determine the percentage of candidates with misrepresentation. Thirteen out of 18 studies (eight residency and five fellowship) found in the literature from 1995 to 2008 reported sufficient details to perform a recalculation. The most common type of misrepresentation reported was listing nonexistent articles, followed by errors in authorship order and nonauthorship. After recalculation, the mean percentage of candidates with misrepresentation per applicant pool decreased significantly (7.2% to 4.9%, P = .03048). No study characteristic, such as sample size, was found to be predictive of the percentage of applicants with misrepresentation. No difference was found in the percentage of applicants with misrepresentation in residency versus fellowship programs. The variance in study results of misrepresentation decreases when uniform inclusion criteria are applied. Caution must be used in directly comparing the results of these studies as originally reported. Program directors should be aware that self-promotion in the authorship list is a common form of misrepresentation.

    To design and implement 2 pharmaceutical industry elective courses and assess their impact on students' selection of advanced pharmacy practice experiences (APPEs) and pursuit of pharmaceutical industry fellowships. Two 2-credit-hour elective courses that explored careers within the prescription and nonprescription pharmaceutical drug industries were offered for second- and third-year pharmacy students in a doctor of pharmacy (PharmD) degree program. The impact of the courses on pharmacy students' pursuit of a pharmaceutical industry fellowship was evaluated based on responses to annual graduating students' exit surveys. A greater percentage (17.9%) of students who had taken a pharmaceutical industry elective course pursued a pharmaceutical industry fellowship compared to all PharmD graduates (4.8%). Of the students who enrolled in pharmaceutical industry APPEs, 31% had taken 1 of the 2 elective courses. Exposure to a pharmaceutical industry elective course within a college or school of pharmacy curriculum may increase students' interest in pursuing pharmaceutical industry fellowships and enrolling in pharmaceutical industry APPEs.

    A trained cadre of medical education scholars with a focus on methodologically sound research techniques is needed to ensure development of innovations that can be translated to educational practice, rigorous evaluation of instructional strategies, and progress toward improving patient care outcomes. Most established educational programs are aimed at existing faculty members and focus primarily on the development of teaching and leadership skills. At the 2012 Academic Emergency Medicine (AEM) consensus conference, "Education Research in Emergency Medicine: Opportunities, Challenges, and Strategies for Success," a breakout session was convened to develop training recommendations for postgraduate fellowship programs in medical education scholarship that would enable residency graduates to join academic faculties armed with the skills needed to perform research in medical education. Additionally, these graduates would enjoy the benefits of established mentorships. A group of 23 medical education experts collaborated to address the following objectives: 1) construct a formal needs assessment for fellowship training in medical education scholarship in emergency medicine (EM), 2) compare and contrast current education scholarship programs in both EM and non-EM specialties, and 3) develop a set of core curriculum guidelines for specialized fellowship training in medical education scholarship in EM. Fellowship-trained faculty need to be proficient in learner instruction and assessment, organizational leadership, curriculum development, educational methodology, and conducting generalizable hypothesis-driven research to improve patient care.

    2015-02-01

    Remarkably little is known about what constitutes a good residency or fellowship training program. In contrast to entry-level programs, the job of residency and fellowship educators is sometimes more subtle and difficult to articulate. Developing advanced clinical reasoning, communication skills, use of evidence, and patient-management approaches beyond entry-level competencies for students of various levels of education and backgrounds creates unique and diverse teaching challenges. There is no gold standard and precious little evidence to guide us on how best to sequence and pace residency/fellowship curricula, integrate mentoring into didactic and clinical coursework, conduct examinations, and measure the impact of training on patient care. To this end, we'd like to congratulate Drs Rodeghero, Wang, Flynn, Cleland, Wainner, and Whitman on their paper, “The Impact of Physical Therapy Residency or Fellowship Education on Clinical Outcomes for Patients With Musculoskeletal Conditions.” This is a significant first step in the effort to explore that most important challenge of any health profession's educational initiatives: did training result in improved patient outcomes?

    In 2008, it was shown that 11% of applications to a primary care sports medicine program contained unverifiable citations for publications. In 2009, the American Medical Society for Sports Medicine changed the application requirements, requiring proof that all claimed citations (publications and presentations) be included with the fellowship application. We determined the rate of unverifiable academic citations in applications to primary care sports medicine fellowship programs after proof of citations was required. We retrospectively examined all applications submitted to 5 primary care sports medicine fellowship programs across the country for 3 academic years (2010-2013), out of 108 to 131 programs per year. For claimed citations that did not include proof of publication or presentation, we attempted to verify them using PubMed and Google Scholar searches, a medical librarian search, and finally directly contacting the publisher or sponsoring conference organization for verification. Fifteen of 311 applications contained at least 1 unverifiable citation. The total unverifiable rate was 4.8% (15 of 311) for publications and 11% (9 of 85) for presentations. These rates were lower than previously published within the same medical subspecialty. After requiring proof of publication and presentation citations within applications to primary care sports medicine fellowship programs, unverifiable citations persisted but were less than previously reported.

    2015-02-01

    Publication misrepresentation by residency applicants has been well documented, but fewer studies have investigated it in fellowship applicants, specifically in pain medicine. We therefore sought to evaluate the demographics of pain medicine fellowship applicants and the type, number, and accuracy of referenced publications they reported. Applications to the Multidisciplinary Pain Medicine fellowship program in the Mayo School of Graduate Medical Education, Rochester, Minnesota were reviewed for three consecutive academic years (2009-2012). Demographic information and publications claimed by applicants were compiled, and publications were scrutinized by a medical librarian for accuracy. Over a 3-year period, 179 fellowship applications were received. Of the 179 applicants, more than half (106 [59%]) listed at least one publication. Of 324 listed publications, 263 were verifiable; of these, 14 (5.3%) were deemed fraudulent, and six (2.3%) contained an inaccuracy possibly conferring a competitive advantage. In our small sample size, we found no difference in the rate of publications or in the accuracy of listed publications across subspecialties, or between US medical graduates and international medical graduates. The lack of national data, specifically on applicant misrepresentation, due to the heretofore absence of a universal application process or match, impedes assessment of the extent to which these findings are representative of the national applicant pool. We observed notable trends (few female applicants; numerous international medical graduate applicants) different from those reported by other specialties. Despite the low rate (5.3%) of fraudulent publications, fellowship program directors and selection committees should be aware of this possibility to ensure selection of fellows with the highest degree of professional and ethical integrity.

    The entire healthcare workforce needs to be educated to better care for older adults. The purpose of this study was to determine whether fellows are being trained to teach, to assess the attitudes of fellowship directors toward training fellows to be teachers, and to understand how to facilitate this type of training for fellows. A nine-question survey adapted from a 2001 survey issued to residency program directors inquiring about residents-as-teachers curricula was developed and administered. The survey was issued electronically and sent out three times over a 6-week period. Of 144 ACGME-accredited geriatric fellowship directors from geriatric, internal medicine, and family medicine departments who were e-mailed the survey, 101 (70%) responded; 75% had an academic affiliation, 15% had a community affiliation, and 10% did not report. Academic and community programs required their fellows to teach, but just 55% of academic and 29% of community programs offered teaching skills instruction as part of their fellowship curriculum; 67% of academic programs and 79% of community programs felt that their fellows would benefit from more teaching skill instruction. Program directors listed fellow (39%) and faculty (46%) time constraints as obstacles to creation and implementation of a teaching curriculum. The majority of fellowship directors believe that it is important for geriatric fellows to become competent educators, but only approximately half of programs currently provide formal instruction in teaching skills. A reproducible, accessible curriculum on teaching to teach that includes a rigorous evaluation component should be created for geriatrics fellowship programs. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

    Previous studies have highlighted unique needs of international medical graduates (IMG) during their transition into medical training programs; however, limited data exist on IMG needs specific to fellowship training. We conducted the following mixed-method study to determine IMG fellow training needs during the transition into fellowship training programs in psychiatry and surgery. The authors conducted a mixed-methods study consisting of an online survey of IMG fellows and their supervisors in psychiatry or surgery fellowship training programs and individual interviews of IMG fellows. The survey assessed (a) fellows' and supervisors' perceptions on IMG challenges in clinical communication, health systems, and education domains and (b) past orientation initiatives. In the second phase of the study, IMG fellows were interviewed during the latter half of their fellowship training, and perceptions regarding orientation and adaptation to fellowship in Canada were assessed. Survey data were analyzed using descriptive and Mann-Whitney U statistics. Qualitative interviews were analyzed using grounded theory methodology. The survey response rate was 76% (35/46) and 69% (35/51) for IMG fellows and supervisors, respectively. Fellows reported the greatest difficulty with adapting to the hospital system, medical documentation, and balancing one's professional and personal life. Supervisors believed that fellows had the greatest difficulty with managing language and slang in Canada, the healthcare system, and an interprofessional team. In Phase 2, fellows generated themes of disorientation, disconnection, interprofessional team challenges, a need for IMG fellow resources, and a benefit from training in a multicultural setting. Our study results highlight the need for IMG specific orientation resources for fellows and supervisors. Maslow's Hierarchy of Needs may be a useful framework for understanding IMG training needs.

  14. Curie point depth and heat flow from spectral analysis of aeromagnetic data over the northern part of Western Desert, Egypt

    Saada, Saada Ahmed

    2016-11-01

    The present work aims to estimate the Curie point depth and the surface heat flow for the northern part of the Western Desert using aeromagnetic data. Applying spectral analysis to aeromagnetic anomalies has provided equitable promising geological results, useful for further geothermal or petroleum exploration. The total intensity aeromagnetic map was first reduced to the north magnetic pole to correct the shape and position of different magnetic anomalies over their causative bodies. Secondly, the short wavelengths were removed to enhance the deeper long wavelengths related to the deep sources. Spectral analysis indicates that the area is underlined by an average Curie point depth of about 27 km. This implies an average thermal heat flow (53 mW/m2) lower than the average global heat flow. The investigated area was divided into eighteen blocks, where the average depths to centroid and top of the magnetic source were estimated for each block. The results of this work show a general depth increase of the magnetic boundaries from 24.5 km in the southern area to 33 km at the northern part. The calculated surface heat flow decreases from about 56 to 42 mW/m2 in the same direction. Consequently, this area is characterized by its low geothermal gradient and surface heat flow. This low geothermal gradient indicates that the upper mantle contributes to the magnetic features at the northern offshore parts. This work also recommends by deep drilling for petroleum exploration and production within the Egyptian Mediterranean Sea exploration strip.

  15. Extrinsic Curie temperature and spin reorientation changes in Nd{sub 2}Fe{sub 14}B/{alpha}-Fe nanocomposites

    The Curie temperatures and spin reorientation temperatures of a series of four melt-spun nanocomposite materials comprised of Nd{sub 2}Fe{sub 1}4B and varying amounts of {alpha}-Fe were measured using independent techniques. The phase constitution and grain size was assessed with synchrotron x-ray diffraction; the Curie temperatures were measured by differential thermal analysis (DTA) and dc SQUID magnetometry in the temperature range 375 K {le} T {le} 800 K, whereas the spin reorientation transition temperature was determined from ac susceptibility measurements taken in the range 10 K {le} T {le} 300 K. The Curie temperature increases with increasing excess iron content, resulting in a 18 {degree} enhancement over the Curie temperature of pure Nd{sub 2}Fe{sub 14}B for 27 wt% excess {alpha}-Fe. The spin reorientation temperatures are depressed from the single-crystal value by an average of 10 degrees. Both anomalous effects are attributed to intergranular exchange coupling present in the alloys, although the effects of uncompensated stress between the constituent phases cannot be ruled out The experimental results suggest that while the Curie temperature of the Nd{sub 2}Fe{sub 14}B phase may be extrinsically enhanced significantly beyond the bulk value, possibly extending the range of applications of this compound, the anisotropy may be simultaneously lowered, impeding the attainment of high coercivities in these alloys.

    2014-12-01

    Pediatric orthopaedic fellowship applicants commonly use online-based resources for information on potential programs. Two primary sources are the San Francisco Match (SF Match) database and the Pediatric Orthopaedic Society of North America (POSNA) database. We sought to determine the accessibility and quality of information that could be obtained by using these 2 sources. The online databases of the SF Match and POSNA were reviewed to determine the availability of embedded program links or external links for the included programs. If not available in the SF Match or POSNA data, Web sites for listed programs were located with a Google search. All identified Web sites were analyzed for accessibility, content volume, and content quality. At the time of online review, 50 programs, offering 68 positions, were listed in the SF Match database. Although 46 programs had links included with their information, 36 (72%) of them simply listed http://www.sfmatch.org as their unique Web site. Ten programs (20%) had external links listed, but only 2 (4%) linked directly to the fellowship web page. The POSNA database does not list any links to the 47 programs it lists, which offer 70 positions. On the basis of a Google search of the 50 programs listed in the SF Match database, web pages were found for 35. Of programs with independent web pages, all had a description of the program and 26 (74%) described their application process. Twenty-nine (83%) listed research requirements, 22 (63%) described the rotation schedule, and 12 (34%) discussed the on-call expectations. A contact telephone number and/or email address was provided by 97% of programs. Twenty (57%) listed both the coordinator and fellowship director, 9 (26%) listed the coordinator only, 5 (14%) listed the fellowship director only, and 1 (3%) had no contact information given. The SF Match and POSNA databases provide few direct links to fellowship Web sites, and individual program Web sites either do not exist or do not

    The United States (US) National Aeronautics and Space Administration (NASA) Exploration Systems Mission Directorate (ESMD) provides university faculty fellowships that prepare the faculty to implement engineering design class projects that possess the potential to contribute to NASA ESMD objectives. The goal of the ESMD is to develop new capabilities, support technologies and research that will enable sustained and affordable human and robotic space exploration. In order to create a workforce that will have the desire and skills necessary to achieve these goals, the NASA ESMD faculty fellowship program enables university faculty to work on specific projects at a NASA field center and then implement the project within their capstone engineering design class. This allows the senior - or final year - undergraduate engineering design students, the opportunity to develop critical design experience using methods and design tools specified within NASA's Systems Engineering (SE) Handbook. The faculty fellowship projects focus upon four specific areas critical to the future of space exploration: spacecraft, propulsion, lunar and planetary surface systems and ground operations. As the result of a 2010 fellowship, whereby faculty research was conducted at Marshall Space Flight Center (MSFC) in Huntsville, Alabama (AL), senior design students in the Mechanical and Aerospace Engineering (MAE) department at the University of Alabama in Huntsville (UAH) had the opportunity to complete senior design projects that pertained to current work conducted to support ESMD objectives. Specifically, the UAH MAE students utilized X-TOOLSS (eXploration Toolset for the Optimization Of Launch and Space Systems), an Evolutionary Computing (EC) design optimization software, as well as design, analyze, fabricate and test a lunar regolith burrowing device - referred to as the Lunar Wormbot (LW) - that is aimed at exploring and retrieving samples of lunar regolith.

    Zhang, Chuanqian; Johnson, Duane T; Brazel, Christopher S

    2008-12-01

    This study develops and solves two-dimensional convective-conductive coupled partial differential equations based on Pennes' bio-heat transfer model using low Curie temperature nanoparticles (LCTNPs) to illustrate thermal behavior quantitatively within tumor-normal composite tissue by establishing a multi-region finite difference algorithm. The model combines NEel relaxation and temperature-variant saturation magnetization derived from Brillouin Equation and Curie-Weiss Law. The numerical results indicate that different deposition patterns of LCTNP and boundary conditions directly effect the steady state temperature distribution. Compared with high Curie temperature nanoparticles (HCTNPs), optimized distributions of LCTNPs within tumorous tissue can be used to control the temperature increase in tumors for hyperthermia treatment using an external magnetic field while healthy tissue surrounding a tumor can be kept closer to normal body tissue, reducing the side effects observed in whole body and regional hyperthermia therapy.

    The (15)N-HSQC spectra of low-spin cyano-met-myoglobin and high-spin fluoro-met-myoglobin were assigned and dipole-dipole-Curie-spin cross-correlated relaxation rates measured. These cross-correlation rates originating from the dipolar (1)H-(15)N interaction and the dipolar interaction between the (1)H and the Curie spin of the paramagnetic center contain long-range angular information about the orientation of the (1)H-(15)N bond with respect to the iron-(1)H vector, with information measurable up to 11 A from the metal for the low-spin complex, and between 10 to 25 A for the high-spin complex. Comparison of the experimental data with predictions from crystal structure data showed that the anisotropy of the magnetic susceptibility tensor in low spin cyano-met-myoglobin significantly influences the cross-correlated dipole-dipole-Curie-spin relaxation rates.

    Ferromagnetic–paramagnetic phase transitions in classical and quantum thin films have been studied up to 50 mono-layers using effective field theory with two-site cluster approximation. Variation of the Curie temperature as a function of film thickness has been examined. The relative shift of the Curie temperature from the corresponding bulk value has been investigated in terms of the shift exponent λ. We have found that shift exponent λ clearly depends on the strength of the ferromagnetic exchange coupling of the surface. Moreover, we have not observed any significant difference between classical and quantum exponents for a particular model.

    Structural and magnetic changes on invar Fe{sub 64}Ni{sub 36} alloy (T{sub C}=500 K) produced by mechanical milling followed by heating up to 1073 K, were investigated by neutron diffraction, magnetization measurements, X-ray diffraction under high pressures and X-ray absorption at both Fe and Ni K-edges. We argue that the strain induced in the Fe{sub 64}Ni{sub 36} material after this treatment mainly affects the Fe sites due to the magnetovolume coupling, the most notorious feature being the increase of the Curie temperature ({delta}T{sub C}=70 K).

  3. The study of high Curie temperature ferromagnetism properties in Mn-doped SiC thin film

    2015-01-01

    Full Text Available Mn-doped 3C-SiC film has been prepared onto the Si (111 substrate by employing a molecular beam epitaxy method. The experimental analysis establishes that the prepared sample shows the ferromagnetic property with a relatively high Curie temperature (Tc of 355 K, which is an exciting phenomenon on account of the scarceness in the SiC-based diluted magnetic semiconductor. The analysis derived from the X-ray diffraction and absorption spectroscopy patterns indicates that Mn atoms should react with Si atoms and then form Mn4Si7 compounds. Combined with the theoretical simulation, it is speculated that a new alloy phase of Mn4Si7Cx maybe appear, which should be responsible for the exceptionally high Tc ferromagnetic behavior in the sample.

    Mn1-xAlxCoGe alloys with a second order transition were produced by arc-melting method. The substitution of Mn by Al increased the Curie temperature (TC) from 260.5 K to 300.8 K, the magnetic entropy change (|ΔSM|) decreased from 3.78 J·Kg-1K-1 to 2.35 J·Kg-1K-1 under a field change of Δμ0H=5 T. In addition, the |ΔSM| well linearly depends on the H2/3 around TC. Furthermore, the relative cooling power (RCP) can reach 242.3 J·Kg-1 with a large full width at half maximum of |ΔSM| (75.5 K) for x=0.02. The decrease of |ΔSM| is explained by the corresponding monotonical decrease of magnetic moment per formula unit.

    We demonstrate by magneto-transport measurements that a Curie temperature as high as 200 K can be obtained in nanostructures of (Ga,Mn)As. Heavily Mn-doped (Ga,Mn)As films were patterned into nanowires and then subject to low-temperature annealing. Resistance and Hall effect measurements demonstrated a consistent increase of T(C) with decreasing wire width down to about 300 nm. This observation is attributed primarily to the increase of the free surface in the narrower wires, which allows the Mn interstitials to diffuse out at the sidewalls, thus enhancing the efficiency of annealing. These results may provide useful information on optimal structures for (Ga,Mn)As-based nanospintronic devices operational at relatively high temperatures.

    The effects of heavy rare earth (RE) additions on the Curie temperature (TC) and magnetocaloric effect of the Fe-RE-B-Nb (RE = Gd, Dy and Ho) bulk metallic glasses were studied. The type of dopping RE element and its concentration can easily tune TC in a large temperature range of 120 K without significantly decreasing the magnetic entropy change (ΔSM) and refrigerant capacity (RC) of the alloys. The observed values of ΔSM and RC of these alloys compare favorably with those of recently reported Fe-based metallic glasses with enhanced RC compared to Gd5Ge1.9Si2Fe0.1. The tunable TC and large glass-forming ability of these RE doped Fe-based bulk metallic glasses can be used in a wide temperature range with the final required shapes.

    The structural and magnetic properties of Mn{sub 5}Ge{sub 3}C{sub x} films prepared at elevated substrate temperatures T{sub S} are investigated. In particular, films with x{>=}0.5 and T{sub S}=680 K exhibit a strongly enhanced Curie temperature T{sub C}=445 K compared to bulk Mn{sub 5}Ge{sub 3} with T{sub C}=304 K while at the same time the average Mn moment decreases from 2.6 to 1 {mu}{sub B}. Structural analysis of these films suggests that the carbon is interstitially incorporated into the voids of Mn octahedra of the hexagonal Mn{sub 5}Si{sub 3}-type structure giving rise to a lattice compression. The enhanced ferromagnetic stability in connection with the lattice compression is interpreted in terms of an Mn-Mn interaction mediated by C based on a change in the electronic structure.

    2015-01-01

    This article examines the poetic contribution of Valerie Gillies, Edinburgh Makar (or poet of the city) from 2005-2008, to the Edinburgh Marie Curie Hospice Quiet Room, a new contemplation space for patients, families, and staff. In collaboration with others, Gillies created a transitional space for the Quiet Room, centered on the display of her sonnet, "A Place Apart." This space functions to comfort visitors to the Quiet Room by relocating them in their surroundings and offering the solace provided by nature and history. With this project, her first as Edinburgh Makar, Gillies redefines the role of the poet as healer and advocates for newer forms of palliative care that focus on patients' spiritual and emotional, as well as physical, wellbeing.

    We present the electronic structures, magnetic exchange interactions and Curie temperature (T{sub C}) of GaMnN and GaMnAs calculated by self-interaction-corrected local-density approximation (LDA-SIC). In GaMnAs, the LDA-SIC results of T{sub C} do not differ so much from the LDA results. Both the LDA and LDA-SIC values are in a good agreement with the experimental data. In GaMnN, on the other hand, the ferromagnetic exchange interactions are enhanced due to the suppression of antiferromagnetic super-exchange interaction, resulting in T{sub C} higher than the LDA results.

    Christensen, Mark; Christensen, Heidi K

    2015-01-01

    Residency training clearly impacts physicians' approach toward fellowship in Primary Care Sports Medicine. Although the Accreditation Council for Graduate Medical Education sets strict standards for all programs, family medicine and emergency medicine training differ a great deal in general and provide physicians from both backgrounds varied perspectives and skill sets. The family physician acquires a substantial amount of experience in continuity of care and integration of health care into a patient's everyday life. On the other hand, the emergency physician receives exceptional training in the management of acutely ill and injured patients and leadership of a large health care team. Furthermore, while the emergency physician may be skilled in procedures such as fracture reduction and diagnostic ultrasound, the family physician is proficient in developing patient rapport and compliance with a treatment plan. Although physicians from different backgrounds may start with many differences, fellowship training is essential in bridging those gaps.

    2013-08-15

    The factors motivating pharmacy students to pursue residency and fellowship training in 2011 versus 1993 were assessed. A survey replicating previous research was electronically sent to 794 residency directors and 29 fellowship program directors with a request to forward the survey to current residents and fellows. A similar survey was sent to 124 colleges of pharmacy with a request to forward the survey to the faculty member most involved with residency and fellowship promotion within their doctor of pharmacy (Pharm.D.) curriculum. Participants were asked to rank leading motivating factors and barriers to pharmacy students pursuing these programs. Additional data collected included when and the methods by which these programs are promoted. Among residents and fellows, 865 usable surveys were returned. The leading motivating reasons for residents and fellows to pursue training were "to gain knowledge and experience," a "desire for specialized training," [corrected] and "understood as a prerequisite for certain jobs." A total of 124 U.S. pharmacy schools were surveyed, and 65 (52%) returned completed responses. "Understood as a prerequisite for certain jobs," "faculty stressing importance," and "recognition of the new and challenging roles for pharmacists in the future" were the factors most frequently cited by faculty members. Compared with previous research, a new factor motivating pharmacy students to pursue residency and fellowship training is the consideration that these opportunities are a prerequisite for certain jobs. This development may be attributable to trends in the supply and demand of pharmacists, the recognition of the value in these programs by major pharmacy organizations, and the evolving role of pharmacists in direct patient care.

    Professionalism is paramount to the formation and functioning of new graduate critical care nurses. In this project, a sample of 110 new graduate nurses used a descriptive self-report electronic survey with Hall's Professionalism Inventory Scale. A great percentage of these new graduate critical care nurse fellows with high professionalism scores may be related to their participation in the Critical Care Nurse Fellowship orientation program. Perhaps, Nursing Professional Development specialists should incorporate classes on professional advancement planning for new graduate nurses.

    Full Text Available The application and interview process for gynecologic oncology fellowship is highly competitive, time-consuming and expensive for applicants. We conducted a survey of successfully matched gynecologic oncology fellowship applicants to assess problems associated with the interview process and identify areas for improvement. All Society of Gynecologic Oncology (SGO list-serve members who have participated in the match program for gynecologic oncology fellowship were asked to complete an online survey regarding the interview process. Linear regression modeling was used to examine association between year of match, number of programs applied to, cost incurred, and overall satisfaction. Two hundred and sixty-nine eligible participants reported applying to a mean of 20 programs [range 1–45] and were offered a mean of 14 interviews [range 1–43]. They spent an average of $6000 [$0–25,000], using personal savings (54%, credit cards (50%, family support (12% or personal loans (3%. Seventy percent of respondents identified the match as fair, and 93% were satisfied. Interviewees spent a mean of 15 [0–45] days away from work and 37% reported difficulty arranging coverage. Linear regression showed an increase in number of programs applied to and cost per applicant over time (p < 0.001 between 1993 and 2016. Applicants who applied to all available programs spent more (p < 0.001 than those who applied to programs based on their location or quality. The current fellowship match was identified as fair and satisfying by most respondents despite being time consuming and expensive. Suggested alternative options included clustering interviews geographically or conducting preliminary interviews at the SGO Annual Meeting.

    This study aims to evaluate a leadership fellowship program through perspectives of Ethiopian women medical faculty participants. An intensive two-week leadership development fellowship was designed for women faculty from Ethiopian medical schools and conducted from 2011-2015 at the University of Wisconsin-School of Medicine and Public Health in Madison, Wisconsin. Nine Ethiopian women working in early- or mid-level academic positions were selected. Semi-structured interviews were conducted with the fellows. Transcripts were reviewed through qualitative analysis to assess the perceived impact of the training on their careers. Three male academic leaders were interviewed to solicit feedback on the program. Eight of 9 fellows were interviewed. Themes describing the benefits of the fellowship included: increased awareness of gender inequities; enhanced motivation for career advancement; increased personal confidence; and improved leadership skills. Fellows provided suggestions for future training and scaling up efforts to promote gender equity. Male leaders described the benefits of men promoting gender equity within academic health centers. This paper provides evidence that targeted brief training programs can enhance women's motivation and skills to become effective leaders in academic medicine in Ethiopia. Promoting gender equity in academic medicine is an important strategy to address health workforce shortages and to provide professional role models for female students in the health professions.

  4. The effect of residency and fellowship type on hand surgery clinical practice patterns.

    2015-01-01

    The Accreditation Council for Graduate Medical Education requires accredited fellowship programs to exhibit proficiency in six broadly defined domains; however, core competencies specifically mandated for hand surgery training have yet to be established. Several studies have demonstrated significant disparities in exposure to essential skills and knowledge between orthopedic surgery- and plastic surgery-based hand surgery fellowship programs. To determine whether significant discrepancies also exist after fellowship between hand surgeons trained in orthopedic surgery and those trained in plastic surgery, clinical practice patterns were evaluated. A 20-question survey was created and distributed electronically to American Society for Surgery of the Hand and American Association for Hand Surgery members. Responses were compared using descriptive statistics. Nine hundred eighty-two hand surgeons (76 percent orthopedic and 24 percent plastic) responded, representing a 39 percent response rate. Most plastic surgery hand practices were academic-based (41 percent), whereas orthopedic practices were private (67 percent). More orthopedic hand surgeons worked in multipractitioner practices than plastic surgeons (54 percent versus 30 percent; p digital replantation cases (53 percent versus 22 percent; p < 0.05) but treated significantly fewer open reduction and internal fixation distal radius fractures. Orthopedic and plastic surgery hand surgeons differ significantly in their clinical practice patterns. Differences in clinical exposure during training are reflected in practice and persist over time. Referral patterns and practice situations are also contributors to ultimate practice patterns.

    Study Design. A retrospective study was used to review fellowship applications over 3 years. Objectives. To assess the prevalence of research misrepresentation in orthopedic fellowship applications, and to compare such activity between subspecialties (e.g. spine, sports, hand). Summary of Background Data. Competition for orthopedic surgery fellowships is intense. The applicant pool includes orthopedic, plastic, and general surgeons, as well as neurosurgeons. Residency and fellowship training programs in other disciplines have documented shocking levels of misrepresentation in the curriculum vitae of prospective applicants. However, no study has looked at orthopedic residents applying for subspecialty fellowship programs. Methods. A retrospective analysis investigated 280 applications for fellowship positions in the department of orthopedic surgery at the authors' academic institution from 1996 to 1998 inclusively. To allow for press and publication delays, a minimum 24-month follow-up period was instituted. The listings of applicants' research publications were analyzed for evidence of misrepresentation through an exhaustive literature search. Only the most obvious confirmable discrepancies were labeled as misrepresentations. The results then were compared with those found in studies conducted in other fields: gastroenterology fellowship, emergency medicine residency, pediatric residency, dermatology residency, orthopedic residency, and medical faculty applications. Results. Among 280 (54%) applicants for orthopedic surgery candidates, 151 claimed journal publications. It was found that 16 (10.6%) of these 151 applicants had misrepresented their citations. This rate was highest in spine fellowship applicants (20%). However, considering the numbers available, this was not significantly different among the various subspecialty fellowship applicants (P>0.1). In addition, various demographic data did not correlate with the rate of misrepresentation (P>0.1). These

    The Marie Curie Initial Training Network »Isotopic Tools as Novel Sensors of Earth Surfaces Resources - IsoNose« is an alliance of eight international partners and five associated partners from science and industry. The project is coordinated at the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences and will run until February 2018. In the last 15 years advances in novel mass-spectrometric methods have opened opportunities to identify "isotopic fingerprints" of virtually all metals and to make use of the complete information contained in these fingerprints. The understanding developed with these new tools will ultimately guide the exploitation of Earth surface environments. However, progress in bringing these methods to end-users depends on a multi transfer of knowledge between (1) isotope Geochemistry and Microbiology, Environmental Sciences (2), Economic Geology and (3) instrument developers and users in the development of user-friendly and new mass spectrometric methods. IsoNose will focus on three major Earth surface resources: soil, water and metals. These resources are currently being exploited to an unprecedented extent and their efficient management is essential for future sustainable development. Novel stable isotope techniques will disclose the processes generating (e.g. weathering, mineral ore formation) and destroying (e.g. erosion, pollution) these resources. Within this field the following questions will be addressed and answered: - How do novel stable isotope signatures characterize weathering processes? - How do novel stable isotope signatures trace water transport? - How to use novel stable isotope as environmental tracers? - How to use novel stable isotope for detecting and exploring metal ores? - How to improve analytical capabilities and develop robust routine applications for novel stable isotopes? Starting from the central questions mentioned above the IsoNose activities are organized in five scientific work packages: 1

    Purpose Given the scarcity of malignant phyllode tumours of the breast and the absence of consensus regarding their management justify the need for institutional retrospective evaluations of clinical practices. Patients and methods Retrospective study with central pathology review of the 25 consecutive patients treated at the Institut Curie (Paris, France) between 1969 and 2006 for non metastatic malignant phyllodes tumors of the breast. The median follow-up was 65 months (7-257 months). Results Median age at diagnosis was 52 years (20-64 years). Breast surgery was conservative in five patients (20%). Surgical margins were wide (> 10 mm), narrow, involved or unknown in respectively 17 (68%), three (12%), three (12%) and two (8%) patients. Median tumour size was 65 mm (12-250 mm). Adjuvant radiotherapy was delivered in seven (28%) patients (two patients, post tumor-ectomy; five patients, post mastectomy) and 13 patients (52%) received anthracycline-based adjuvant chemotherapy. Five-year overall survival rate was 91% (95% CI, 80-100%). Five patients (20%) developed distant metastases (one after chemotherapy) and three (12%) locoregional relapse (one after tumor-ectomy and unknown margin without radiotherapy, two after mastectomy and involved margins with radiotherapy). Conclusion Wide breast surgery (that can be conservative in selected patients) is the mainstay of the treatment of non metastatic malignant phyllodes tumors of the breast. To better determine the respective roles of adjuvant systemic treatment and radiotherapy, further clinical studies and the search for new prognostic and predictive factors remain necessary.

    We previously demonstrated that a pediatric cardiology boot camp can improve knowledge acquisition and decrease anxiety for trainees. We sought to determine if boot camp participants entered fellowship with a knowledge advantage over fellows who did not attend and if there was moderate-term retention of that knowledge. A 2-day training program was provided for incoming pediatric cardiology fellows from eight fellowship programs in April 2016. Hands-on, immersive experiences and simulations were provided in all major areas of pediatric cardiology. Knowledge-based examinations were completed by each participant prior to boot camp (PRE), immediately post-training (POST), and prior to the start of fellowship in June 2016 (F/U). A control group of fellows who did not attend boot camp also completed an examination prior to fellowship (CTRL). Comparisons of scores were made for individual participants and between participants and controls. A total of 16 participants and 16 control subjects were included. Baseline exam scores were similar between participants and controls (PRE 47 ± 11% vs. CTRL 52 ± 10%; p = 0.22). Participants' knowledge improved with boot camp training (PRE 47 ± 11% vs. POST 70 ± 8%; p cardiology knowledge after the training program and had excellent moderate-term retention of that knowledge. Participants began fellowship with a larger fund of knowledge than those fellows who did not attend.

  9. Low-temperature dynamics of the Curie-Weiss Model: Periodic orbits, multiple histories, and loss of Gibbsianness

    Ermolaev, Victor

    2010-01-01

    We consider the Curie-Weiss model at a given initial temperature in vanishing external field evolving under a Glauber spin-flip dynamics corresponding to a possibly different temperature. We study the limiting conditional probabilities and their continuity properties and discuss their set of points of discontinuity (bad points). We provide a complete analysis of the transition between Gibbsian and non-Gibbsian behavior as a function of time, extending earlier work for the case of independent spin-flip dynamics. For initial temperature bigger than one we prove that the time-evolved measure stays Gibbs forever, for any (possibly low) temperature of the dynamics. In the regime of heating to low-temperatures from even lower temperatures, when the initial temperature is smaller than the temperature of the dynamics, and smaller than 1, we prove that the time-evolved measure is Gibbs initially and becomes non-Gibbs after a sharp transition time. We find this regime is further divided into a region where only symmetr...

    The effects of heavy rare earth (RE) additions on the Curie temperature (T{sub C}) and magnetocaloric effect of the Fe-RE-B-Nb (RE = Gd, Dy and Ho) bulk metallic glasses were studied. The type of dopping RE element and its concentration can easily tune T{sub C} in a large temperature range of 120 K without significantly decreasing the magnetic entropy change (ΔS{sub M}) and refrigerant capacity (RC) of the alloys. The observed values of ΔS{sub M} and RC of these alloys compare favorably with those of recently reported Fe-based metallic glasses with enhanced RC compared to Gd{sub 5}Ge{sub 1.9}Si{sub 2}Fe{sub 0.1}. The tunable T{sub C} and large glass-forming ability of these RE doped Fe-based bulk metallic glasses can be used in a wide temperature range with the final required shapes.

    Magnetic refrigeration (MR) technology stands a good chance of replacing the conventional gas compression system (CGCS) of refrigeration due to its unique features such as high efficiency, low cost as well as being environmental friendly. Its operation involves the use of magnetocaloric effect (MCE) of a magnetic material caused by application of magnetic field. Manganite-based material demonstrates maximum MCE at its magnetic ordering temperature known as Curie temperature (TC). Consequently, manganite-based material with TC around room temperature is essentially desired for effective utilization of this technology. The TC of manganite-based materials can be adequately altered to a desired value through doping with appropriate foreign materials. In order to determine a manganite with TC around room temperature and to circumvent experimental challenges therein, this work proposes a model that can effectively estimates the TC of manganite-based material doped with different materials with the aid of support vector regression (SVR) hybridized with gravitational search algorithm (GSA). Implementation of GSA algorithm ensures optimum selection of SVR hyper-parameters for improved performance of the developed model using lattice distortions as the descriptors. The result of the developed model is promising and agrees excellently with the experimental results. The outstanding estimates of the proposed model suggest its potential in promoting room temperature magnetic refrigeration through quick estimation of the effect of dopants on TC so as to obtain manganite that works well around the room temperature.

    PARTNER (Particle Training Network for European Radiotherapy) is a project funded by the European Commission's Marie Curie-ITN funding scheme through the ENLIGHT Platform for 5.6 million Euro. PARTNER has brought together academic institutes, research centres and leading European companies, focusing in particular on a specialized radiotherapy (RT) called hadron therapy (HT), interchangeably referred to as particle therapy (PT). The ultimate goal of HT is to deliver more effective treatment to cancer patients leading to major improvement in the health of citizens. In Europe, several hundred million Euro have been invested, since the beginning of this century, in PT. In this decade, the use of HT is rapidly growing across Europe, and there is an urgent need for qualified researchers from a range of disciplines to work on its translational research. In response to this need, the European community of HT, and in particular 10 leading academic institutes, research centres, companies and small and medium-sized enterprises, joined together to form the PARTNER consortium. All partners have international reputations in the diverse but complementary fields associated with PT: clinical, radiobiological and technological. Thus the network incorporates a unique set of competencies, expertise, infrastructures and training possibilities. This paper describes the status and needs of PT research in Europe, the importance of and challenges associated with the creation of a training network, the objectives, the initial results, and the expected long-term benefits of the PARTNER initiative.

    Full Text Available RESUMO: Este trabalho analisou três edições da revista Ciência Hoje das Crianças, em que Einstein, Darwin e Marie Curie são apresentados. Frente ao desafio de divulgar a vida e a obra desses cientistas de forma adequada às crianças, para análise dos artigos consideramos a linguagem utilizada, as imagens apresentadas e, principalmente, a representação da revista sobre os cientistas. A metodologia de análise do material é inspirada nos trabalhos de Bakhtin sobre dialogismo e na compreensão por meio dos procedimentos discursivos, verbais e visuais com que a revista interpela e dialoga com as crianças. Os resultados mostram que a chancela editorial opta por focar a infância dos cientistas e uma imagem do cientista curioso e aventureiro. Entretanto, veicula-se nos artigos analisados uma visão estereotipada do cientista como alguém que já se anunciava cientista. Reitera-se a importância da Ciência Hoje das Crianças para a promoção da leitura e a democratização da linguagem de divulgação científica para crianças.

  15. Paediatric cardiology fellowship training: effect of work-hour regulations on scholarly activity.

    Ronai, Christina; Lang, Peter

    2017-01-01

    In 2003, work-hour regulations were implemented by the Accreditation Council for Graduate Medical Education. Much has been published regarding resident rest and quality of life as well as patient safety. There has been no examination on the effect of work-hour restrictions on academic productivity of fellows in training. Paediatric subspecialty fellows have a scholarly requirement mandated by the American Board of Pediatrics. We have examined the impact of work-hour restrictions on the scholarly productivity of paediatric cardiology fellows during their fellowship. We conducted a literature search for all paediatric cardiology fellows between 1998 and 2007 at a single academic institution as first or senior authors on papers published during their 3-year fellowship and 3 years after completion of their categorical fellowship (n=63, 30 fellows before 2003 and 33 fellows after 2003). The numbers of first- or senior-author fellow publications before and after 2003 were compared. We also collected data on final paediatric cardiology subspecialty career choice. There was no difference in the number of fellow first-author publications before and after 2003. Before work-hour restrictions, the mean number of publications per fellow was 2.1 (±2.2), and after work-hour restrictions it was 2.0 (±1.8), (p=0.89). By subspecialty career choice, fellows who select electrophysiology, preventative cardiology, and heart failure always published within the 6-year time period. Since the implementation of work-hour regulations, total number of fellow first-authored publications has not changed. The role of subspecialty choice may play a role in academic productivity of fellows in training.

    The purpose of this study was to determine the incidence and predictors of nonverifiable research publications among applicants to a trauma and surgical critical care fellowship program. All complete applications submitted to our trauma and surgical critical care fellowship program were prospectively collected for 4 application cycles (2009 to 2012). All publications listed by applicants were tabulated and underwent verification using MEDLINE and direct journal search with verification by a team of professional health sciences librarians. Demographics and academic criteria were compared between applicants with nonverifiable and verifiable publications. A total of 100 applicants reported 301 publications. Of those, 20 applicants (20%) listed 32 papers (11%) that could not be verified. These applicants comprised 30% of those with 1 or more peer-reviewed publications. There were no significant differences in sex (male, 55% nonverifiable vs 60% verifiable, p = 0.684) or age (34.3 ± 6.6 years vs 34.2 ± 5.0 years, p = 0.963). There were no differences with regard to citizenship status (foreign medical graduates, 20% nonverifiable vs 28% verifiable, p = 0.495). Applicants with nonverified publications were less likely to be in the military (0% vs 14%, p = 0.079), more likely to have presented their work at surgical meetings (80% vs 58%, p = 0.064), and to be individuals with 3 or more peer-reviewed publications (55% vs 25%, p = 0.009). In this analysis of academic integrity, one-fifth of all applicants applying to a trauma and surgical critical care fellowship program and 30% of those with 1 or more peer-reviewed publications had nonverifiable publications listed in their curricula vitae. These applicants were less likely to be in the military, more likely to have presented their work at surgical meetings and to have 3 or more peer-reviewed publications.

    Communication skills are a competency highlighted by the Accreditation Council on Graduate Medical Education; yet, little is known about the frequency with which trainees receive formal training or what programs are willing to invest. We sought to answer this question and designed a program to address identified barriers. We surveyed pediatric fellowship program directors from all disciplines and, separately, pediatric hematology/oncology fellowship program directors to determine current use of formal communication skills training. At our institution, we piloted a standardized patient (SP)-based communication skills training program for pediatric hematology/oncology fellows. Twenty-seven pediatric hematology/oncology program directors and 44 pediatric program directors participated in the survey, of which 56% and 48%, respectively, reported having an established, formal communication skills training course. Multiple barriers to implementation of a communication skills course were identified, most notably time and cost. In the pilot program, 13 pediatric hematology/oncology fellows have participated, and 9 have completed all 3 years of training. Precourse assessment demonstrated fellows had limited comfort in various areas of communication. Following course completion, there was a significant increase in self-reported comfort and/or skill level in such areas of communication, including discussing a new diagnosis (p =.0004), telling a patient they are going to die (p =.005), discussing recurrent disease (p communicating a poor prognosis (p =.002), or responding to anger (p ≤.001). We have designed a concise communication skills training program, which addresses identified barriers and can feasibly be implemented in pediatric hematology/oncology fellowship.

    The role of the physician scientist in biomedical research is increasingly threatened. Despite a clear role in clinical advances in translational medicine, the percentage of physicians engaged in research has steadily declined. Several programmatic efforts have been initiated to address this problem by providing time and financial resources to the motivated resident or fellow. However, this decline in physician scientists is due not only to a lack of time and resources but also a reflection of the uncertain path in moving from residency or postdoctoral training toward junior faculty. This article is a practical guide to the milestones and barriers to successful faculty achievement after residency or fellowship training.

    The Partners HealthCare system's Clinical Fellowship in Pathology Informatics (Boston, MA, USA) faces ongoing challenges to the delivery of its core curriculum in the forms of: (1) New classes of fellows annually with new and varying educational needs and increasingly fractured, enterprise-wide commitments; (2) taxing electronic health record (EHR) and laboratory information system (LIS) implementations; and (3) increasing interest in the subspecialty at the academic medical centers (AMCs) in what is a large health care network. In response to these challenges, the fellowship has modified its existing didactic sessions and piloted both a network-wide pathology informatics lecture series and regular "learning laboratories". Didactic sessions, which had previously included more formal discussions of the four divisions of the core curriculum: Information fundamentals, information systems, workflow and process, and governance and management, now focus on group discussions concerning the fellows' ongoing projects, updates on the enterprise-wide EHR and LIS implementations, and directed questions about weekly readings. Lectures are given by the informatics faculty, guest informatics faculty, current and former fellows, and information systems members in the network, and are open to all professional members of the pathology departments at the AMCs. Learning laboratories consist of small-group exercises geared toward a variety of learning styles, and are driven by both the fellows and a member of the informatics faculty. The learning laboratories have created a forum for discussing real-time and real-world pathology informatics matters, and for incorporating awareness of and timely discussions about the latest pathology informatics literature. These changes have diversified the delivery of the fellowship's core curriculum, increased exposure of faculty, fellows and trainees to one another, and more equitably distributed teaching responsibilities among the entirety of the

    An applicant shortage for vascular surgery (VS) residencies exists despite an increase in available training positions created to meet the growing demands for vascular surgeons. After 3 years of practice as an American Board of Surgery (ABS)-certified/board-eligible general surgeon, the author of this study attended an accredited 1-year VS training fellowship and received an ABS certificate of Added Qualifications in VS. The purpose of this review was to investigate the implications completing a vascular fellowship has had on VS procedure patterns, vascular procedure competency, clinical practice, career, and lifestyle with the aim of attracting trainees to the field of VS. The author's operative logs were reviewed retrospectively to summarize vascular procedures performed before and after the vascular fellowship. Statistical analysis was performed comparing the types and volume of vascular procedures before and after the vascular fellowship. Changes in professional career and personal life also were examined. The author performed 401 vascular procedures during 2.8 years as a general surgeon. In the first 3.4 years after the vascular fellowship, vascular procedure volume increased to 1563. The mean number of vascular procedures performed per year increased from 143.2 as a general surgeon to 459.7 as a vascular surgeon. The three major differences in vascular procedures occurring after the vascular fellowship were (1) a threefold increase in the number of vascular procedures performed, (2) a shift from major open to venous and endovascular procedures, and (3) an increase in case complexity. Specializing in VS also has resulted in increased career opportunities, more career satisfaction, a direct financial benefit, and more flexibility for lifestyle and family. Because of these positive changes, the author encourages medical students and residents interested in VS to explore the specialty early, seek vascular surgeons to serve as mentors, and enter one of the new VS

    Purpose: To evaluate the treatment results of patients (pts) with Figo stage IB2, IIA, IIB cervical carcinoma (C.C.) treated with preoperative radio chemotherapy, followed by extended radical hysterectomy. Patients and methods: Retrospective study of 148 women treated to the Curie Institute for operable Figo Stage IB2 to IIB, biopsy proved C.C.. Among them, 70 pts, median age 46 years, were treated using the same regimen associating primary radio cis-platinum based chemotherapy,intracavitary LDR brachytherapy, followed by extended radical hysterectomy. Kaplan-Meier estimates were used to draw survival curves. Comparisons of survival distribution were assessed by the log-rank test. Results: Complete histological local-regional response was obtained in 56% of the pts (n = 39). Residual macroscopic or microscopic disease in the cervix was observed in 28 pts (40%). All but one had in situ microscopic residual C.C.. Lateral residual disease in the parametria was also present in nine pts, all with residual C.C.. Pelvic lymph nodes were free from microscopic disease in 56 pts (80%). Eight of 55 (11%) radiological N0 patients had microscopic nodal involvement, as compared to 6/15 (40%) radiological N1 (p = 0.03). Seventeen pts (25%) had residual cervix disease but negative nodes. After median follow-up of 40 months (range, 8-141), 38/70 patients (54.1%) are still alive and free of disease, six (8.6%) alive with disease, and 11 (15.8%) patients were lost for follow-up but free of disease. Conclusion: The treatment of locally advanced C.C. needs a new multidisciplinary diagnostic and treatment approach using new therapeutic arms to improve the survival and treatment tolerance among women presenting this disease.

    Effect of pressure on the Curie temperature T{sub C} of the Mn-rich Heusler alloys Mn{sub 2}RuSn and Mn{sub 2}PdSn has been investigated by measuring the temperature dependence of initial permeability at various pressures up to 10 kbar. It was found that the Curie temperatures of Mn{sub 2}RuSn and Mn{sub 2}PdSn decrease with increasing pressure. The pressure derivatives of T{sub C} were estimated to be −0.59 K/kbar for Mn{sub 2}RuSn and −0.80 K/kbar for Mn{sub 2}PdSn. On the basis of the experimental results, the relationship between the magnetic transition temperature and the Mn-Mn distance is discussed.

    New technologies that allow geothermal energy production in colder conditions result in interest for geothermal exploration in low heat flux regions that were previously overlooked. The Province of Québec, eastern Canada, is such a case. It is a large and cold area with a low amount of heat flux measurements, and mapping the Curie point depth is appealing as an exploration tool due to the scarcity of the direct data. For that purpose, we have revisited a methodology to estimate the Curie point depth using a fractal source distribution model and aeromagnetic data. Our methodology relies on a statistical model of crustal magnetization having a constant magnetization direction and random magnetization amplitude. The shape of the radial average of the logarithm of the power spectrum of magnetic anomalies is predicted using this model. The model parameters (thickness and depth to the top of the magnetic layer, the fractal exponent β and the constant C') are obtained by calculating the best fit between the theoretical and observed radial power spectra using a non-linear least-square algorithm. Rather than using a constant value for the fractal exponent β over the whole study area, which would overcorrect the shape of the radially averaged power spectra in some zones, we propose a new calibration workflow based on heat flux measurements and lithology. This workflow includes the use of sequential Gaussian simulations (SGS) of heat flux data to enlarge the limited available dataset. The use of SGS also allows quantifying the uncertainty and the range of the predicted Curie point depths. This work contributes to mapping the Curie point depth at large scale and help identifying potential areas for further detailed exploration programs and potential geothermal energy production in the Province of Québec.

    To describe a sustainable program of teaching and implementing quality improvement (QI) in a 12-month sleep medicine fellowship. We created a QI curriculum based on Accreditation Council for Graduate Medical Education (ACGME) and American Board of Medical Specialty (ABMS) Part IV Maintenance of Certification (MOC) requirements for QI. Two program faculty with prior QI training volunteered to mentor fellows. Our institution's central QI office houses QI experts who teach QI across the health system. One of these experts, referred to as the "QI consultant," helped us adapt QI teaching materials to include 4 online modules and 5 group sessions. Fellows worked in teams to complete 2 data-guided QI cycles. The curriculum required 29 hours for fellows, 18 hours for faculty, and 55 hours for the QI consultant; now that teaching materials have been created, the QI consultant's involvement will decrease over time. Post-curriculum surveys showed that fellows' knowledge of QI concepts increased, as did their confidence performing QI activities. Fellows' QI projects objectively improved timeliness and quality of care for patients. Sleep medicine fellows and QI faculty mentors evaluated the curriculum positively. The curriculum met ACGME requirements for QI, and fellows and mentoring faculty received ABMS Part IV MOC credit upon completion of the curriculum. A QI curriculum can successfully be implemented into a 12-month sleep medicine fellowship to increase sleep medicine fellows' QI knowledge and confidence, meet ACGME and MOC requirements, and contribute to care of patients with sleep disorders.

    Our nation faces unprecedented challenges in caring for older adults. Geriatricians who provide care and teach geriatrics are underrepresented in the workforce, especially in non-metropolitan communities. In Michigan, geriatricians and geriatrics fellowship (GF) programs are clustered in the Southeast, suggesting that training site demographics may influence fellows' career location decisions. A project was undertaken at Michigan State University to determine if an established family medicine residency network (FMRN) could facilitate the accreditation of new GF programs in non-metropolitan communities, recruit fellows, and retain graduates to practice and teach in neighboring areas. A team (department chair, appointed GF network director, site program directors, and education specialists) conducted participating site needs and readiness assessments, facilitated collaboration between GF programs, assisted with completion of new program applications, led development of a curriculum utilizing shared instructional resources and evaluation tools, and provided career counseling to fellows. Two GF programs were accredited and accepted applicants. Ongoing cooperative efforts resulted in the writing of a GF curriculum, organization of a joint Observed Structured Clinical Evaluation (OSCE), and monthly information-sharing teleconferences with program directors. Following training, graduates have chosen to practice in areas underserved by geriatricians in Michigan and elsewhere. Early experience with this model of GF development indicates that new fellowships can be established in community-based residencies that competitively recruit and train fellows who are inclined to practice in areas of greatest need. Creation of more non-metropolitan GF programs could provide a means to stabilize and redistribute the geriatrician workforce.

    The American Association of Physicists in Medicine (AAPM) sponsors two summer undergraduate research programs to attract top performing undergraduate students into graduate studies in medical physics: the Summer Undergraduate Fellowship Program (SUFP) and the Minority Undergraduate Summer Experience (MUSE). Undergraduate research experience (URE) is an effective tool to encourage students to pursue graduate degrees. The SUFP and MUSE are the only medical physics URE programs. From 2001 to 2012, 148 fellowships have been awarded and a total of $608,000 has been dispersed to fellows. This paper reports on the history, participation, and status of the programs. A review of surveys of past fellows is presented. Overall, the fellows and mentors are very satisfied with the program. The efficacy of the programs is assessed by four metrics: entry into a medical physics graduate program, board certification, publications, and AAPM involvement. Sixty-five percent of past fellow respondents decided to pursue a graduate degree in medical physics as a result of their participation in the program. Seventy percent of respondents are currently involved in some educational or professional aspect of medical physics. Suggestions for future enhancements to better track and maintain contact with past fellows, expand funding sources, and potentially combine the programs are presented.

    Full Text Available In the present study, professional conduct of clinical teachers in Tehran University of Medical Sciences in Iran was assessed by their residents (n=292 and fellowships (n=48 using a standard questioner called self-reported measurement equipment. This evaluation was a descriptive cross-sectional study. Professionalism was questioned in four domains including clinical teacher-patient, clinical teacher-student, inter-professional and clinical teacher-self relationships. Accordingly, mean scores of the teachers in cases of clinical teacher-patient; clinical teacher-student, inter-professional (teamwork and clinical teacher-self relations were 61%, 62.2%, 60.6% and 57.6%, respectively. Generally, the teachers achieved 60.35% of the positive scores, and as a result, they were assessed intermediate in the professional behaviors. The residents and fellowships stated that they were not completely satisfied with their teacher's professional conduct and had hidden concerns. It shows that the clinical teachers in our project may not be ideal role models. As a result, developing a comprehensive professionalism and implementing regulations to ensure a successful professionalism are necessary. The precise evaluation of professional conduct in clinical faculty could encourage the maintenance of professional behaviors and potentially decrease negative role modeling and positively influence the hidden curriculums. Operational approaches to formulating regulations and appropriate measures for establishing professional ethics are of great importance.

    Full Text Available The narrative in Genesis 18:1–15 deals with God’s visit to Abraham at Mamre. The general tendency in the interpretation of this narrative is to focus on Abraham’s hospitality. It is usually interpreted as an example of his righteousness, in line with Hebrews 13:2, or with the test motive of the Greek myth of the birth of Orion. These interpretations, however, seem to be in conflict with the narrator’s own theological views.This study, therefore, attempts to explore the view point of the author of the Fellowship Narrative (Gn 18:1–15 within the context of the larger Abraham narrative (Gn 11:27–25:11. The method used for the investigation is mainly that of narrative criticism. Attention is paid to the narrator’s various literary skills: ‘linking structure with preceding episode’ (Gn 18:1a, the ‘sandwiched structure’ of the larger context (Gn 18:1–21:7, the unique plot sequence, as well as repeated clue words and phrases (such as ‘laugh’, ‘Sarah’ and ‘this time next year’. These literary aspects are used by the narrator to depict the faithfulness of the Lord who fulfils what he promised. The conclusion of this study overturns the traditional interpretations of the Fellowship Narrative.

    Baculoviruses are used as microbial insecticides, protein expression vectors, epitope display platforms, and most recently as vectors for gene therapy. Understanding the mechanisms that control baculovirus host-range and tissue tropisms are important for assessing their safety and for improving their properties for these biotechnology applications. In the past two decades some progress has been made and several baculovirus genes that influence host-range have been identified. Despite this progress, our understanding of the underlying mechanisms that restrict baculovirus host-range is still limited. Here we review what is currently known about baculovirus genes that influence virus host-range.

    The behavior of a three-dimensional isotropic Heisenberg ferromagnet in the presence of a magnetic field H is investigated in the random phase approximation (RPA) near the Curie temperature T{sub c}. It is shown that the magnetization M at the Curie temperature T{sub c} is described by the law M(T=T{sub c})∼H{sup 1/5} and the initial magnetic susceptibility χ{sub 0} at temperatures T≥T{sub c} is given by χ{sub 0}(T≥T{sub c})∼(T−T{sub c}){sup −2}. It means that in the RPA the critical exponents for a three-dimensional Heisenberg ferromagnet coincide with the critical exponents for the Berlin-Kac spherical model of a ferromagnet rather than with the critical exponents of the mean field approximation (MFA). Hence it follows as well that, when a magnetic field H is risen from H=0 to H=H{sub a}, the magnetic entropy S{sub M} will be decreased as ΔS{sub M}(T=T{sub c})∼−H{sub a}{sup 4/5} at the Curie temperature T{sub c} and as ΔS{sub M}(T>T{sub c})∼−(T−T{sub c}){sup −3}H{sub a}{sup 2} at temperatures T>T{sub c}.

The solid solutions show a single phase perovskite structure, and the content of BiCoO3 has a significant effect on the microstructure of ceramics. The BFC-BTx ceramics exhibit improved Curie temperature Tc, together with increased piezoelectric properties. In particular, x=0.6% BFC-BTx ceramics, with a Curie temperature, Tc, of ∼488 °C, show optimum piezoelectric properties of d33=167 pC/N, kp=0.32. The combination of good piezoelectric properties and high Tc makes these ceramics suitable for elevated temperature piezoelectric devices.

  20. Forearc structure in the Lesser Antilles inferred from depth to the Curie temperature and thermo-mechanical simulations

    Imaging deep active volcanic areas remains a challenge in our understanding of their activity and evolution, especially in subduction zones. Study of magnetic anomalies is appropriate to access such dynamics in depth. The magnetic anomaly pattern of the Lesser Antilles Arc (LAA) subduction is studied through Curie Point Depth (CPD), interpreted as the depth of the 580 °C isotherm, and developed to better assess the deep thermal structure of the arc. The depth of the estimated CPD exhibits a complex topography. Keeping in mind the overall uncertainty associated with this method, a main doming is evidenced below the Guadeloupe archipelago. Its apex is shifted towards the ancient arc, suggesting a very hot state of the fore-arc/arc domain. To better understand the LAA thermal state, we perform 2D thermo-mechanical simulations of the subduction zone. Recalling that magnetite is a serpentinization by-product, we simulate water transfer triggered by slab dehydration to test the assumption of fore-arc serpentinization suggested by the positive magnetic anomaly in the vicinity of the Guadeloupe archipelago. In this area, the subduction-induced arc lithosphere hydration and related weakening trigger a fast heating of the upper plate by basal convective removal. This process of fast arc lithosphere thinning may apply where simultaneously the volcanic arc is split in two and normal convergence is high enough. As serpentinization strongly decreases P-wave velocity, we propose a new interpretation of a published seismic profile below Guadeloupe. The seismic layer previously interpreted as the arc lower crust may rather be a layer of serpentinized mantle, as supported by spatial correlations between gravimetric and magnetic anomalies. Consequently, at the scale of Guadeloupe Island, the fore-arc Moho would be shallower than initially assumed, with a dome shape more consistent with both the extensive deformation active since the Oligocene in the inner fore-arc and the CPD doming.

  1. Engineering of the Curie temperature of epitaxial Sr1-xBaxTiO3 films via strain

    The impact of strain on the structural and electrical properties of epitaxial Sr1-xBaxTiO3 films grown on single crystalline DyScO3 (110), TbScO3 (110), and GdScO3 (110) substrates is presented. X-ray diffraction measurements demonstrate that all films are grown epitaxially. The tensile in-plane strain is only partially compensated by a contraction of the out-of-plane lattice parameter. As a result, the volume of the unit cell of the Sr1-xBaxTiO3 film increases due to the tensile strain, and the resulting Poisson ratio of the film is ν ≈ 0.33, which is larger than but still close to the literature values of ν ≈ 0.23 for unstrained defect-free SrTiO3. The Curie temperature derived from the temperature dependence of the in-plane dielectric response leads to a strain-temperature phase diagram for the epitaxial Sr1-xBaxTiO3 films. The experimental data show a deviation from the linear dependence predicted by the Landau thermodynamic theory for large strain (>1.2%). However, using the equilibrium thermodynamic analysis, we can demonstrate that this deviation arises from the relaxation of the strain due to defect formation in the film. The result reveals that in addition to the nominal misfit strain, the defect formation strongly affects the effective strain and, thus, the dielectric response of epitaxially grown ferroelectric films.

    Full Text Available Background: Several reports have described worse perioperative outcomes of laparoscopic gastric bypass procedure during learning curve, which improved after completion of one-year fellowship training. Aims: The aim of this study was to evaluate the immediate impact of fellowship training on perioperative complications and outcomes of various bariatric procedures. Materials and Methods: One hundred initial patients who underwent laparoscopic gastric banding, laparoscopic Roux-en-Y gastric bypass, laparoscopic vertical sleeve gastrectomy, and robotically-assisted laparoscopic biliopancreatic diversion with duodenal switch by a single fellowship trained surgeon were analyzed. Results: Overall average Body Mass Index (BMI of the patients was 45.9 kg/m 2 , age was 47.5 years, and the American Society of Anesthesiologist Score was 2.89. There were no intraoperative, major 30-day complications, or open conversions. Average operative time was 62 minutes in gastric banding, 160 minutes in gastric bypass, 119 minutes in vertical sleeve gastrectomy, and 320 minutes in biliopancreatic diversion. Length of stay ranged from 0.5 day after gastric banding to 3.9 days after biliopancreatic diversion. The perioperative complications and outcomes are comparable with those reported by experienced surgeons. No mortality occurred in this series. Conclusions: Bariatric fellowship ensured skills acquisition for new surgeons to safely and effectively perform various types of bariatric operations, with minimal perioperative complications and excellent outcomes.

    The AAAS Mass Media Science &Engineering Fellowship program has succeeded in training scientists to become more effective communicators for more than 30 years. The program places advanced science, engineering and mathematics students at media sites to work as science reporters for ten weeks each summer. AAAS places between 15 to 20 students a year at newspapers, magazines and radio stations. Our goal is to create better science communicators who understand their role in fostering the public's understanding of science. Fellows leave the program with a greater awareness of how to communicate complex issues by making the connection as to why people should be interested in certain developments, and more specifically, how they will impact their communities. 2004 AGU Fellow Rei Ueyama put her lessons learned to good use during her Fellowship at the Sacramento Bee. "In a regional paper like The Bee, a (story) also had to have a local touch. I needed to show why people in Sacramento (or California) should bother to read the story. One example is the story I wrote about seeding the ocean with iron particles to fight global warming. Since ocean fertilization is a global issue, I had to clearly specify the reason why The Bee and not The New York Times was running the story. The local angle I chose was to point out that the core group of scientists involved in this study was from Monterey Bay, Calif." Many alumni tell us the program has been an integral force in shaping the course of their career. Similarly, sites often report that having a scientist on staff is an invaluable resource that allows them to cover additional science stories as well as report some technical stories in more depth. The American Geophysical Union has sponsored a Mass Media Fellow since 1997. Sponsorship allows affiliate program partners to establish connections with young professionals in their field. They are then also able to take advantage of the communication skills resident in their alumni base

    Full Text Available The Partners HealthCare system′s Clinical Fellowship in Pathology Informatics (Boston, MA, USA faces ongoing challenges to the delivery of its core curriculum in the forms of: (1 New classes of fellows annually with new and varying educational needs and increasingly fractured, enterprise-wide commitments; (2 taxing electronic health record (EHR and laboratory information system (LIS implementations; and (3 increasing interest in the subspecialty at the academic medical centers (AMCs in what is a large health care network. In response to these challenges, the fellowship has modified its existing didactic sessions and piloted both a network-wide pathology informatics lecture series and regular "learning laboratories". Didactic sessions, which had previously included more formal discussions of the four divisions of the core curriculum: Information fundamentals, information systems, workflow and process, and governance and management, now focus on group discussions concerning the fellows′ ongoing projects, updates on the enterprise-wide EHR and LIS implementations, and directed questions about weekly readings. Lectures are given by the informatics faculty, guest informatics faculty, current and former fellows, and information systems members in the network, and are open to all professional members of the pathology departments at the AMCs. Learning laboratories consist of small-group exercises geared toward a variety of learning styles, and are driven by both the fellows and a member of the informatics faculty. The learning laboratories have created a forum for discussing real-time and real-world pathology informatics matters, and for incorporating awareness of and timely discussions about the latest pathology informatics literature. These changes have diversified the delivery of the fellowship′s core curriculum, increased exposure of faculty, fellows and trainees to one another, and more equitably distributed teaching responsibilities among

  11. Study by neutron diffusion of magnetic fluctuations in iron in the curie temperature region; Etude des fluctuations d'aimantation dans le fer au voisinage de la temperature de curie par diffusion des neutrons

    The critical diffusion of neutrons in iron is due to the magnetisation fluctuations which occur in ferromagnetic substances in the neighbourhood of the Curie temperature. The fluctuations can be described in correlation terms; a correlation function {gamma}{sub R{sub vector}} (t) is defined, {gamma}{sub R{sub vector}} (t) = mean value of the scalar product of a reference spin and a spin situated at a distance (R) from the first and considered at the instant t. In chapter I we recall the generalities on neutron diffusion cross-sections; a brief summary is given of the theory of VAN HOVE, who has shown that the magnetic diffusion cross section of neutrons is the Fourier transformation of the correlation function. In chapter Il we study the spatial dependence of the correlation function, assumed to be independent of time. It can then be characterised by two parameters K{sub 1} and r{sub 1}, by means of which the range and intensity of the correlations can be calculated respectively. After setting out the principle of the measurement of these parameters, we shall describe the experimental apparatus. The experimental values obtained are in good agreement with the calculations, and the agreement is better if it is supposed that the second and not the first neighbours of an iron atom are magnetically active, as proposed by Neel. In chapter III we study the evolution with time of the correlation function; this evolution is characterised by a parameter {lambda} depending on the temperature, which occurs in the diffusion equation obeyed by the magnetisation fluctuations: {delta}M{sub vector}/{delta}t = {lambda} {nabla}{sup 2} M{sub vector}. The principle of the measurement of {lambda} is given, after which the modifications carried out on the experimental apparatus mentioned in chapter II are described. The results obtained are then discussed and compared with the theoretical forecasts of De Gennes, mode by using the

    Full Text Available Stephen J Heller, Jeffrey L TokarDepartment of Medicine, Fox Chase Cancer Center, Philadelphia, PA, USAAbstract: Rapid growth in the field of advanced gastrointestinal endoscopy has led to an increase in specialized therapeutic endoscopy fellowships. The cornerstones of these programs are training in endoscopic retrograde cholangiopancreatography (ERCP and endoscopic ultrasound. These procedures are more complex and challenging to master than routine colonoscopy and upper endoscopy, and in the case of ERCP, higher risk. The concentration of the educational experience in the hands of relatively fewer trainees with specialized interest in advanced endoscopy has resulted in providing a focused cohort of graduating fellows with higher case volumes in training, which likely enhances diagnostic and therapeutic success and safer performance of these procedures. Endoscopic simulators, although not currently in widespread use, have the potential to improve advanced procedural training without jeopardizing patient safety.Keywords: gastrointestinal endoscopy, training, procedures, safety

    Surgical diseases have recently been shown to be a major cause of global morbidity and mortality. Effective methods to decrease the burden of surgical disease and provide care in resource-poor settings are unknown. An opportunity to meet this need exists through collaborative efforts to train local surgeons in specialty care, such as pediatric general surgery. We present a novel model for the provision of surgical care and education in a resource-poor setting via a collaborative Global Surgery Fellowship program. Through Partners in Health in Haiti, this program placed a fully trained pediatric surgeon at an established rural hospital, both to temporarily serve that community and to teach local surgeons pediatric surgical care. The Global Surgery Fellow performed the cases presented here during his term, between July 2009 and June 2010. A total of 147 operative procedures were performed on 131 patients over the course of 12 weeks in Haiti. A total of 134 of the 147 total cases performed (91.2%) were educational cases, in which the Fellow operated with and trained one or more of the following: American medical students, American residents, Haitian residents, or Haitian staff surgeons. The Global Surgery Fellowship model overcomes many of the traditional challenges to providing adequate surgical care in resource-poor countries. Specifically, it meets the challenge of providing a broad educational experience for many levels of local and foreign physicians, while working within an established locally run health care system. We believe that this model is generalizable to many resource-poor hospitals with permanent local staff that are open to collaboration. Copyright © 2015 Elsevier Inc. All rights reserved.

    The Objective Structured Clinical Examination (OSCE) appears to be an effective alternative for assessing not only medical knowledge, but also clinical skills, including effective communication and physical examination skills. The purpose of the current study was to implement an OSCE model in a geriatrics fellowship program and to compare the instrument with traditional essay examination. Seventy first- and second-year geriatric fellows were initially submitted to a traditional essay examination and scored from 0 to 10 by a faculty member. The same fellows subsequently underwent an OSCE with eight 10-minute stations covering a wide range of essential aspects of geriatric knowledge. Each OSCE station had an examiner responsible for its evaluation according to a predefined checklist. Checklist items were classified for analysis purposes as clinical knowledge items (CKI) and communication skills items (CSI); fellow responses were scored from 0 to 10.Although essay examinations took from 30 to 45 minutes to complete, 180-200 minutes were required to evaluate fellows using the proposed OSCE method. Fellows scored an average of 6.2 ± 1.2 on the traditional essay examination and 6.6 ± 1.0 on the OSCE (P OSCE scores indicated that average performance on CKI was lower than the average on CSI (6.4 ± 1.1 vs. 8.4 ± 1.1; P examination was similar to their performance on CKI (P = .13). Second-year fellows performed better than first-year fellows on the essay examination (P OSCE was successfully implemented as an educational strategy during a geriatrics fellowship program. Combining different testing modalities may provide the best assessment of competence for various domains of knowledge, skills, and behavior.

  1. What is the chance all your trainees will pass the next Fellowship exam: A statistician's view.

    Your department has had a good track record over many years for preparing trainees to successfully sit for the ACEM Fellowship exam. On average the pass rate for your trainees is over 80%. Then, to your dismay, suddenly only two of five of your trainees pass the latest Fellowship exam. Does this anomaly necessitate an urgent review of your department's training programme, or is it just a statistical quirk? Let us suppose you can prepare candidates so that they all have at least an 80% chance of passing. The probability that all five candidates would have passed is 32.8% (or 0.8(5) ) based on the multiplication rule of probability for independent events. The probability that only two of five passed is 5.1% (or 10 × 0.8(2) × 0.2(3) ) based on the binomial distribution, which is a probability distribution analogous to the normal distribution. The construction of the binomial distribution depends on two parameters: (i) number of candidates sitting ('n'), and (ii) probability of passing for any individual candidate ('P'). The distribution gives the probability that 'x' number of individuals will pass when 'n' number of individuals sit. Thus despite an 80% pass rate historically, the probability that only two of five candidates will pass is not negligible at 5.1%. It is an anomaly, which we may choose not to act on unless it is recurrent, noting it will be expected to occur naturally about one time out of 20. The real challenge is to maintain or increase that individual probability at 80% or higher.

  2. Life after National Science Foundation fellowships: The implications for a graduate student's professional endeavors

    Obarski, Kelly Josephine

    Each year, hundreds of graduate and undergraduate students, participate as Fellows in National Science Foundation GK-12 Grants throughout the U.S. These Fellowships create opportunities for university students to improve their communication skills, teaching proficiencies, and team-building skills, in addition to expanding their interest in educational endeavors in their respective communities while pursuing their college degrees. STEP (Science and Technology Enhancement Project) is one such project. University faculty, public school teachers, and community leaders collaborated together in order to bring scientists into middle and secondary classrooms to focus on increasing student interest and proficiency in science, technology, engineering, and mathematics (STEM) skills. Seventeen Fellows, in the previous four years, designed, developed, and implemented innovative, hands-on lessons in seven local schools. The evaluation team collected a tremendous amount of research evidence focused on the effect of the program on the Fellows while they were participants in the study, but there has been very little data collected about the Fellows after leaving the program. This research study, consisting of two-hour interviews, qualitatively explores how the skills learned while participating in the STEP program affected the Fellows' career and educational choices once leaving the project. This data was analyzed along with historical attitude surveys and yearly tracking documents to determine the effect that participation in the program had on their choices post-STEP. An extensive literature review has been conducted focusing on other GK-12 programs throughout the country, K-16 collaboration, Preparing Future Faculty Programs, as well as on teaching and learning literature. These bodies of literature provide the theoretical basis in which the research is framed in order to assess the impact on Fellow educational and professional choices since leaving the STEP program.

    We evaluated preventive cardiology education in United States cardiology fellowship programs and their adherence to Core Cardiovascular Training Symposium training guidelines, which recommend 1 month of training, faculty with expertise, and clinical experience in cardiac rehabilitation, lipid disorder management, and diabetes management as a part of the prevention curricula. We sent an anonymous survey to United States cardiology program directors and their chief fellow. The survey assessed the program curricula, rotation structure, faculty expertise, obstacles, and recommended improvements. The results revealed that 24% of surveyed programs met the Core Cardiovascular Training Symposium guidelines with a dedicated 1-month rotation in preventive cardiology, 24% had no formalized training in preventive cardiology, and 30% had no faculty with expertise in preventive cardiology, which correlated with fewer rotations in prevention than those with specialized faculty (p = 0.009). Fellows rotated though the following experiences (% of programs): cardiac rehabilitation, 71%; lipid management, 37%; hypertension, 15%; diabetes, 7%; weight management/obesity, 6%; cardiac nutrition, 6%; and smoking cessation, 5%. The program directors cited "lack of time" as the greatest obstacle to providing preventive cardiology training and the chief fellows reported "lack of a developed curriculum" (p = 0.01). The most recommended improvement was for the American College of Cardiology to develop a web-based curriculum/module. In conclusion, most surveyed United States cardiology training programs currently do not adhere to basic preventive cardiovascular medicine Core Cardiovascular Training Symposium recommendations. Additional attention to developing curricular content and structure, including the creation of an American College of Cardiology on-line knowledge module might improve fellowship training in preventive cardiology.

    There are some who suggest that alcoholism and drug abuse are not diseases at all and that they are not consequences of a brain disorder as espoused recently by the American Society of Addiction Medicine (ASAM). Some would argue that addicts can quit on their own and moderate their alcohol and drug intake. When they present to a treatment program or enter the 12 Step Program & Fellowship, many addicts finally achieve complete abstinence. However, when controlled drinking fails, there may be successful alternatives that fit particular groups of individuals. In this expert opinion, we attempt to identify personal differences in recovery, by clarifying the molecular neurobiological basis of each step of the 12 Step Program. We explore the impact that the molecular neurobiological basis of the 12 steps can have on Reward Deficiency Syndrome (RDS) despite addiction risk gene polymorphisms. This exploration has already been accomplished in part by Blum and others in a 2013 Springer Neuroscience Brief. The purpose of this expert opinion is to briefly, outline the molecular neurobiological and genetic links, especially as they relate to the role of epigenetic changes that are possible in individuals who regularly attend AA meetings. It begs the question as to whether "12 steps programs and fellowship" does induce neuroplasticity and continued dopamine D2 receptor proliferation despite carrying hypodopaminergic type polymorphisms such as DRD2 A1 allele. "Like-minded" doctors of ASAM are cognizant that patients in treatment without the "psycho-social-spiritual trio," may not be obtaining the important benefits afforded by adopting 12-step doctrines. Are we better off with coupling medical assisted treatment (MAT) that favors combining dopamine agonist modalities (DAM) as possible histone-deacetylase activators with the 12 steps followed by a program that embraces either one or the other? While there are many unanswered questions, at least we have reached a time when "science

    In this paper we report on the structural and magnetic properties of GeMn layers grown on Ge(001). We show that for the optimized Mn concentration (6%) and for optimized growth temperature (close to 130 C), GeMn samples exhibit a high Curie temperature (higher than 400 K) and Anomalous Hall Effect up to room temperature. Our GeMn layers grown at low temperature (70 C to 130 C) are composed of vertical Mn-rich nano-columns. Samples grown at temperatures higher than 130 C contain GeMn nanoclusters.

    Andersson, S.; Korenivski, V.

    2010-05-01

    Thermal control of exchange coupling between two strongly ferromagnetic layers through a weakly ferromagnetic Ni-Cu spacer and the associated magnetoresistance is investigated. The spacer, having a Curie point slightly above room temperature, can be cycled between its paramagnetic and ferromagnetic states by varying the temperature externally or using joule heating. It is shown that the giant magnetoresistance vanishes due to a strong reduction in the mean free path in the spacer at above ˜30% Ni concentration—before the onset of ferromagnetism. Finally, a device is proposed which combines thermally controlled exchange coupling and large magnetoresistance by separating the switching and the readout elements.

    Full Text Available Curie temperature (TC of anatase Co-doped TiO2 epitaxial thin films was systematically investigated as functions of carrier density (n and Co content (x by electrical transport and magnetization measurements at low temperature regime. The estimated TC from both measurements showed similar TC. For x = 0.03, 0.05, and 0.07, non-monotonic TC vs. n relations were observed, whereas TC was monotonically increasing function of n for x = 0.10. Possible mechanism of high TC ferromagnetism for this compound was discussed.

    José M Malpica

    Full Text Available The distribution of multi-host pathogens over their host range conditions their population dynamics and structure. Also, host co-infection by different pathogens may have important consequences for the evolution of hosts and pathogens, and host-pathogen co-evolution. Hence it is of interest to know if the distribution of pathogens over their host range is random, or if there are associations between hosts and pathogens, or between pathogens sharing a host. To analyse these issues we propose indices for the observed patterns of host infection by pathogens, and for the observed patterns of co-infection, and tests to analyse if these patterns conform to randomness or reflect associations. Applying these tests to the prevalence of five plant viruses on 21 wild plant species evidenced host-virus associations: most hosts and viruses were selective for viruses and hosts, respectively. Interestingly, the more host-selective viruses were the more prevalent ones, suggesting that host specialisation is a successful strategy for multi-host pathogens. Analyses also showed that viruses tended to associate positively in co-infected hosts. The developed indices and tests provide the tools to analyse how strong and common are these associations among different groups of pathogens, which will help to understand and model the population biology of multi-host pathogens.

But, depending on the stellar content the ratio may decline at z>4 (if E/S0-like), flatten off to 6--10 times the local value (if Sbc-like), or continue to rise (if Im-like). We infer that galaxy bulge masses must have grown by a factor of 3--6 over the redshift range 3>z>1, and then changed little since z~1. This suggests that the peak epoch of galaxy formation for massive galaxies is above z~1. We also estimate the duty cycle of luminous AGNs at z>1 to be ~1%, or 10^7 yrs, with sizable scatter.

    Summary Over the last 3 decades, expansion in the scope and complexity of hepatopancreatobiliary (HPB) surgery has resulted in significant improvements in postoperative outcomes. As a result, the importance of dedicated fellowship training for HPB surgery is now well established, and the definition of formal program requirements has been actively pursued by a collaboration of the 3 distinct accrediting bodies within North America. Although major advances have been made in defining minimum case volume requirements, qualitative assessment of the operative experience remains challenging. Our research collaborative (HPB Manpower and Education Study Group) has previously explored the perceived case volume adequacy of core HPB procedures within fellowship programs. We conducted a 1-year follow-up survey targeting the same cohort to investigate the association between operative case volumes and comfort performing HPB procedures within initial independent practice.

    Discussions were given on effects of acid pretreatment and tetralin swelling in Wandoan coal on a Curie point flash pyrolysis (which used a Curie point pyrolyzer). Residue yield loss effects were obtained at 3.9% in hydrochloric acid pretreatment, and 6.2% in acetic acid pretreatment. The effects of tetralin swelling pretreatment were compared in the similar manner in terms of the residue yield loss. The effects were 4.0% in untreated coal, 2.0% in the hydrochloric acid pretreatment, and 0.6% in the acetic acid pretreatment. It is thought that components that can be activated by acetic acid have already been activated, but the remaining components would not be activated by tetralin. Average microporosity (area) in the remaining particle as a whole shows very little difference both in acetic acid pretreated coal and untreated coal. However, with the acetic acid pretreatment, pores smaller than 4{mu}m{sup 2} disappeared, and pores as large as 205 to 411{mu}m{sup 2} increased largely. This phenomenon was observed as an increase in foaming degree under microscopic observation, even if the average microporosity remains equal. Thermoplasticity of the coal increased, and so did volatilization reactivity as a result of the acetic acid pretreatment, resulting in appearance of a large number of large pores. 6 refs., 2 figs., 2 tabs.

  14. DFT+ U study of electronic structure and Curie temperature of A2 B ReO6 (A=Sr, Ca and B=Cr, Fe)

    Science.gov (United States)

    Lee, Alex; Marianetti, Chris

    Re-based double perovskites (DPs) have attracted much attention due to their high Curie temperature (TC) and colossal magneto resistance with large potential for spintronic applications. Here we investigate the electronic and magnetic properties of the Re-based DPs A2 B ReO6 (A=Sr, Ca and B=Cr, Fe) using density functional theory + U (DFT+ U) calculations. While monoclinic Ca2CrReO6 and Ca2FeReO6 (monoclinic) are insulating within GGA+ U, tetragonal Sr2CrReO6 (a0a0c0) and Sr2FeReO6 (a0a0c-) remain metallic. We show that both on-site interaction U and octahedral tilting are critical to obtain the insulating phases. The a0a0c- -phase of Sr2CrReO6 is most stable and insulating with nonzero U, suggesting that the high quality Sr2CrReO6 film on STO substrate can be a semiconductor as reported in recent experiments. We explain that the insulator-to-metal transition (MIT) of Ca2FeReO6 at 140K is predominantly due to a structural phase transition which drives the insulating state. Curie temperatures of Re-based DPs are calculated using the classical Monte Carlo simulations based on the Heisenberg model.

    2016-09-01

    We present an innovative study to generalize Curie Point Depth (CPD) determinations at the scale of oceanic volcanic islands, an approach which has previously focused largely on continental areas. In order to determine the validity of this technique in oceanic environments, we first tested the approach on sets of sea-floor-spreading anomalies. Assuming that magnetic anomalies are concentrated within the oceanic crust and uppermost mantle, the Curie depth should deepen as oceanic lithosphere increases in age and thickness away from spreading centers. The calculated depths to the magnetic bottom are in agreement with this general pattern. On the basis of this test, we then applied the method to La Réunion Island and surrounding oceanic lithosphere. The calculated extent of magnetic sources lies at depths between 10 and 30 km and exhibits a complex topography, presumably caused by a combination of various magmatic and tectonic lithospheric structures. These calculations indicate that magnetic sources extend well below the crust-mantle interface at this location. To the first order, the bottom of the magnetic surface shallows beneath Réunion and Mauritius Islands due to the thermal effect of the hot spot, and deepens away from La Réunion edifice. On the scale of the Mascarene Basin, several discontinuities in the CPD correlate well with major fracture zones.

    Full Text Available Between August 2012 and April 2013 the Career Development Fellowship programme of the Special Programme for Research and Training in Tropical Diseases (World Health Organization underwent an external evaluation to assess its past performance and determine recommendations for future programme development and continuous performance improvement. The programme provides a year-long training experience for qualified researchers from low and middle income countries at pharmaceutical companies or product development partnerships. Independent evaluators from the Swiss Tropical and Public Health Institute and the Barcelona Institute for Global Health used a results-based methodology to review the programme. Data were gathered through document review, surveys, and interviews with a range of programme participants. The final evaluation report found the Career Development Fellowship to be relevant to organizers' and programme objectives, efficient in its operations, and effective in its training scheme, which was found to address needs and gaps for both fellows and their home institutions. Evaluators found that the programme has the potential for impact and sustainability beyond the programme period, especially with the successful reintegration of fellows into their home institutions, through which newly-developed skills can be shared at the institutional level. Recommendations included the development of a scheme to support the re-integration of fellows into their home institutions post-fellowship and to seek partnerships to facilitate the scaling-up of the programme. The impact of the Professional Membership Scheme, an online professional development tool launched through the programme, beyond the scope of the Career Development Fellowship programme itself to other applications, has been identified as a positive unintended outcome.

    Between August 2012 and April 2013 the Career Development Fellowship programme of the Special Programme for Research and Training in Tropical Diseases (World Health Organization) underwent an external evaluation to assess its past performance and determine recommendations for future programme development and continuous performance improvement. The programme provides a year-long training experience for qualified researchers from low and middle income countries at pharmaceutical companies or product development partnerships. Independent evaluators from the Swiss Tropical and Public Health Institute and the Barcelona Institute for Global Health used a results-based methodology to review the programme. Data were gathered through document review, surveys, and interviews with a range of programme participants. The final evaluation report found the Career Development Fellowship to be relevant to organizers' and programme objectives, efficient in its operations, and effective in its training scheme, which was found to address needs and gaps for both fellows and their home institutions.

    It has been argued that UK general practice specialist training should be extended to better prepare GPs for the challenges facing 21st-century health care. Evidence is needed to inform how this should occur. To investigate the experience of recently trained GPs undertaking a 1-year full-time fellowship programme designed to provide advanced skills training in urgent care, integrated care, leadership, and academic practice; and its impact on subsequent career development. Semi-structured interviews conducted longitudinally over 2 years augmented by observational data in the West Midlands, England. Participants were interviewed on at least three occasions: twice while undertaking the fellowship, and at least once post-completion. Participants' clinical and academic activities were observed. Data were analysed using a framework approach. Seven GPs participated in the pilot scheme. The fellowship was highly rated and felt to be balanced in terms of the opportunities for skill development, academic advancement, and confidence building. GPs experienced enhanced employability on completing the scheme, and at follow-up were working in a variety of primary care/urgent care interface clinical and leadership roles. Participants believed it was making general practice a more attractive career option for newly qualified doctors. The 1-year fellowship provides a defined framework for training GPs to work in an enhanced manner across organisational interfaces with the skills to support service improvement and integration. It appears to be well suited to preparing GPs for portfolio roles, but its wider applicability and impact on NHS service delivery needs further investigation. © British Journal of General Practice 2017.

    Molecular technologies offer clinicians the tools to provide high-quality, cost-effective patient care. We evaluated education focused on molecular diagnostics, genomics, and personalized medicine in dermatopathology fellowship. A 20-question online survey was emailed to all (n = 53) Accreditation Council for Graduate Medical Education (ACGME)-accredited dermatopathology training programs in the United States. Thirty-one of 53 program directors responded (response rate = 58%). Molecular training is undertaken in 74% of responding dermatopathology fellowships, with levels of instruction varying among dermatology-based and pathology-based programs. Education differed for dermatology- and pathology-trained fellows in approximately one-fifth (19%) of programs. Almost half (48%) of responding program directors believe that fellows are not currently receiving adequate molecular education although the majority (97%) expect to incorporate additional instruction in the next 2-5 years. Factors influencing the incorporation of relevant education include perceived clinical utility and Accreditation Council for Graduate Medical Education/residency review committee (RRC) requirements. Potential benefits of molecular education include increased medical knowledge, improved patient care, and promotion of effective communication with other healthcare professionals. More than two-thirds (68%) of responding program directors believe that instruction in molecular technologies should be required in dermatopathology fellowship training. Although all responding dermatopathology fellowship program directors agreed that molecular education is important, only a little over half of survey participants believe that their fellows receive adequate instruction. This represents an important educational gap. Discussion among those who oversee fellow education is necessary to best integrate and evaluate teaching of molecular dermatopathology.

    NaZn13型La(Fe,Si)13化合物随Si含量增加,相变性质由一级过渡为二级,化合物晶胞体积收缩,饱和磁化强度降低,居里温度升高。其居里温度与晶胞体积之间的关系不能用Bethe-Slater曲线给出合理的解释。本文利用添加间隙原子碳调节La(Fe,Si)13化合物晶胞体积和居里温度的方法,系统研究了该化合物居里温度与晶胞体积之间的关系。结果发现二者之间的变化规律遵循Jaccarino-Walker模型,即仅有5%甚至更少的3d电子被认为是真正的巡游电子,其余的3d电子仍是局域的。以极化的巡游电子为媒介,局域电子之间产生类似于Ruderman-Kittel-Kasuya-Yosida 的长程相互作用,相互作用的符号和大小与距离呈周期性震荡。随Si含量的增加, La(Fe,Si)13化合物巡游电子数目增加,化合物的居里温度由晶胞体积和巡游电子的浓度共同决定。%In NaZn13 type La(Fe,Si)13 compound, the phase transition nature varies from the first order to the second order, the cell volume contracts, the saturated magnetization decreases and the Curie temperature increases with increasing Si content. In this paper, the relation between the Curie temperature and the cell volume is investigated systematically by introducing the interstitial carbon atoms, which is an efficient method to control the cell volume and the Curie temperature. It is found that the relation between the Curie temperature and the cell volume is consistent with the Jaccarino-Walker model, in which only 5% or less 3d electrons are considered as the itinerant electrons and the others are regarded as the localized ones. With the polarized itinerant electrons used as a medium, the interaction between the 3d localized electrons is similar to Ruderman-Kittel-Kasuya-Yosida interaction, whose sign and magnitude oscillate periodically with distance. The number of the itinerant electrons of the La (Fe,Si)13 increases with the increase of Si content. The Curie

    Searching low sintering temperature material with ultra-high Curie temperature (>800 °C) is urgent to seafloor hydrothermal vents detection. Bi2WO6, as the simplest member of the Aurivillius family was improved to possess ultra-high Curie temperature and ultra-high depolarization temperature by experiment at first time. The crystal structure was determined by ab initio and Rietveld refinement calculations. The symmetry group of ultra-high Curie temperature Bi2WO6 is Aba2 (41). The Curie temperatures of Bi2(1-x)La2xWO6 (x = 0, 0.005, 0.01, 0.02, 0.04) with increasing x are 952 °C, 1008 °C, 905 °C, 853 °C, 822 °C, respectively, and depolarization temperatures of them are around 915 °C, 905 °C, 880 °C, 800 °C, and 725 °C, respectively. The typical properties are as follows: Curie temperature T c = 905 °C, depolarization temperature T d = 880 °C, mechanical quality factor Q m = 621.8, d 33 = 17 pC/N, K 33 = 82.01, tanδ = 0.19 × 10-2 with x value of 0.01.

    For over a decade, the Los Angeles County/University of Southern California Hospital has supported an international fellowship in trauma that provides research experience, education, and opportunity for clinical observation at a high-volume American College of Surgeons (ACS) designated Level I trauma center. We performed a descriptive study of the design, implementation, and results of an international fellowship in trauma and critical care. Fellows from 27 countries throughout the world have actively engaged in trauma research at Los Angeles County/University of Southern California Hospital. Our program involves intensive education and clinical observation components designed to facilitate dissemination of evidence-based trauma practices throughout the world by graduates. The majority of alumni responding to a survey returned to their countries of origin, remaining active in trauma care and research. Motivation for participation varied, but former fellows universally rated their experience highly and stated they would recommend the program to their colleagues. An international research fellowship in trauma and critical care provides foreign medical trainees opportunities for exposure to research and evidence-based practices at a high-volume trauma center. The program is designed to be beneficial to both the participating fellow and sponsoring institution; and is constructed to effectively promote improved trauma education and the dissemination of quality trauma practices internationally.

A retrospective chart review study. The Maine Medical Center Primary Care Sports Medicine Fellowship Program. Presentations were confirmed in the program of the cited meeting or by contacting the sponsoring organization. Publications were verified by performing a MEDLINE search or by cross-referencing in Ulrich's International Periodicals Directory. If the title was listed, the citation was verified by contacting the publisher. Fifty applicants reported research publications. Of those, 14 applications had publications that could not be verified. The overall misrepresentation rate was 11.3%; among applicants claiming publications it was 28%. There was no difference in misrepresentation rate between specialties. Eighteen applicants reported giving national presentations, and nine presentations could not be verified, corresponding to an overall misrepresentation rate of 5.6%. Of applicants claiming presentations, 38.9% had at least one misrepresentation. Applicants to the Maine Medical Center Sports Medicine Fellowship Program were found to have high rates of misrepresentation in their citations of both publications and presentations.

    Physician decision making is partially responsible for the roughly 30% of U.S. healthcare expenditures that are wasted annually on low-value care. In response to both the widespread public demand for higher-quality care and the cost crisis, payers are transitioning toward value-based payment models whereby physicians are rewarded for high-value, cost-conscious care. Furthermore, to target physicians in training to practice with cost awareness, the Accreditation Council for Graduate Medical Education has created both individual objective milestones and institutional requirements to incorporate quality improvement and cost awareness into fellowship training. Subsequently, some professional medical societies have initiated high-value care educational campaigns, but the overwhelming majority target either medical students or residents in training. Currently, there are few resources available to help guide subspecialty fellowship programs to successfully design durable high-value care curricula. The resource-intensive nature of pulmonary and critical care medicine offers unique opportunities for the specialty to lead in modeling and teaching high-value care. To ensure that fellows graduate with the capability to practice high-value care, we recommend that fellowship programs focus on four major educational domains. These include fostering a value-based culture, providing a robust didactic experience, engaging trainees in process improvement projects, and encouraging scholarship. In doing so, pulmonary and critical care educators can strive to train future physicians who are prepared to provide care that is both high quality and informed by cost awareness.

    Pathogens switching to new hosts can result in the emergence of new infectious diseases, and determining which species are likely to be sources of such host shifts is essential to understanding disease threats to both humans and wildlife. However, the factors that determine whether a pathogen can infect a novel host are poorly understood. We have examined the ability of three host-specific RNA-viruses (Drosophila sigma viruses from the family Rhabdoviridae) to persist and replicate in 51 different species of Drosophilidae. Using a novel analytical approach we found that the host phylogeny could explain most of the variation in viral replication and persistence between different host species. This effect is partly driven by viruses reaching a higher titre in those novel hosts most closely related to the original host. However, there is also a strong effect of host phylogeny that is independent of the distance from the original host, with viral titres being similar in groups of related hosts. Most of this effect could be explained by variation in general susceptibility to all three sigma viruses, as there is a strong phylogenetic correlation in the titres of the three viruses. These results suggest that the source of new emerging diseases may often be predictable from the host phylogeny, but that the effect may be more complex than simply causing most host shifts to occur between closely related hosts.

    Full Text Available Abstract Background Fellowships are a component of many professional education programs. They provide opportunities to develop skills and competencies in an environment where time is protected and resources and technical support are more readily available. The SEA-ORCHID fellowships program aimed to increase capacity for evidence-based practice and research synthesis, and to encourage fellows to become leaders in these areas. Methods Fellows included doctors, nurses, midwives and librarians working in the maternal and neonatal areas of nine hospitals in South East Asia. Fellowships were undertaken in Australia and involved specific outputs related to evidence-based practice or research synthesis. Training and support was tailored according to the type of output and the fellow's experience and expertise. We evaluated the fellowships program quantitatively and qualitatively through written evaluations, interviews and follow-up of fellowship activities. Results During 2006-07, 23 fellows from Thailand, Indonesia, Malaysia and the Philippines undertook short-term fellowships (median four weeks in Australia. The main outputs were drafts of Cochrane systematic reviews, clinical practice guidelines and protocols for randomised trials, and training materials to support evidence-based practice. Protocols for Cochrane systematic reviews were more likely to be completed than other outcomes. The fellows identified several components that were critical to the program's overall success; these included protected time, tailored training, and access to technical expertise and resources. On returning home, fellows identified a lack of time and limited access to the internet and evidence-based resources as barriers to completing their outputs. The support of colleagues and senior staff was noted as an important enabler of progress, and research collaborators from other institutions and countries were also important sources of support. Conclusions The SEA

    Teaching quality improvement (QI) is a priority for residency and fellowship training programs. However, many medical trainees have had little exposure to QI methods. The purpose of this study is to review a rigorous and simple QI methodology (define, measure, analyze, improve, and control [DMAIC]) and demonstrate its use in a fellow-driven QI project aimed at reducing the number of delayed and canceled muscle biopsies at our institution. DMAIC was utilized. The project aim was to reduce the number of delayed muscle biopsies to 10% or less within 24 months. Baseline data were collected for 12 months. These data were analyzed to identify root causes for muscle biopsy delays and cancellations. Interventions were developed to address the most common root causes. Performance was then remeasured for 9 months. Baseline data were collected on 97 of 120 muscle biopsies during 2013. Twenty biopsies (20.6%) were delayed. The most common causes were scheduling too many tests on the same day and lack of fasting. Interventions aimed at patient education and biopsy scheduling were implemented. The effect was to reduce the number of delayed biopsies to 6.6% (6/91) over the next 9 months. Familiarity with QI methodologies such as DMAIC is helpful to ensure valid results and conclusions. Utilizing DMAIC, we were able to implement simple changes and significantly reduce the number of delayed muscle biopsies at our institution. © 2015 American Academy of Neurology.

    In the water sciences there is a massive need for graduate students who possess the analytical and technical skills to deal with large datasets and function in the new paradigm of open, collaborative -science. The Global Lake Ecological Observatory Network (GLEON) graduate fellowship program (GFP) was developed as an interdisciplinary training program to supplement the intensive disciplinary training of traditional graduate education. The primary goal of the GFP was to train a diverse cohort of graduate students in network science, open-web technologies, collaboration, and data analytics, and importantly to provide the opportunity to use these skills to conduct collaborative research resulting in publishable scientific products. The GFP is run as a series of three week-long workshops over two years that brings together a cohort of twelve students. In addition, fellows are expected to attend and contribute to at least one international GLEON all-hands' meeting. Here, we provide examples of training modules in the GFP (model building, data QA/QC, information management, bayesian modeling, open coding/version control, national data programs), as well as scientific outputs (manuscripts, software products, and new global datasets) produced by the fellows, as well as the process by which this team science was catalyzed. Data driven education that lets students apply learned skills to real research projects reinforces concepts, provides motivation, and can benefit their publication record. This program design is extendable to other institutions and networks.

    Interest in nephrology careers continues to decline in the United States. The reasons for this declining interest are not fully understood but it is plausible that inadequate exposure to the full spectrum of what a career in nephrology encompasses may be part of the explanation. Inpatient-based nephrology electives have been a common venue for residents to gain exposure to nephrology but little is known regarding the details of such electives and how often they include outpatient experiences. We carried out a national survey of nephrology fellowship training program directors to obtain data on the content of nephrology elective experiences as well as their ideas on how to promote interest in the field. The survey revealed the majority of elective experiences to be either exclusively or heavily inpatient based, with only a small percentage having a substantial outpatient component, particularly in outpatient dialysis or transplantation. Training program directors felt that providing greater outpatient experiences to residents during elective rotations would be an effective means to promote interest in nephrology, along with structured faculty mentoring. Our findings suggest that current approaches to the nephrology elective experience are heavily inpatient-based and might benefit from incorporating much more of the rich spectrum of activities a career in nephrology entails. Hopefully such efforts can create and enhance interest in careers in nephrology and potentially begin a sustained reversal of an unfortunate and serious decline in interest.

    Context This study explores the long-term impact of the Professional Student Mentored Research Fellowship (PSMRF) program at the University of Kentucky College of Medicine (UKCOM) on medical students’ research productivity and career paths. Methods Demographic characteristics, academic profiles, number of publications and residency placements from 2007-2012 were used to assess 119 PSMRF graduates against a comparison cohort of 898 UKCOM (non-PSMRF) students. Results PSMRF students had higher MCAT scores at admission (31.5 ± 0.6 vs. 30.6 ± 0.2, p = 0.007) and achieved higher USMLE Step 1 scores (228 ± 4.2 vs. 223 ± 1.5, p = 0.03) than comparison group. PSMRF students were more likely to publish Pubmed-indexed papers (36.7% vs. 17.9%, p < 0.0001), achieve AOA status (19.3% vs. 8.5%, p = 0.0002) and match to top 25 U.S. News and World Report residency programs (23.4% vs. 12.1%, p = 0.008). A greater proportion of PSMRF fellows matched to top tier competitive specialties (23% vs. 14.2%, p= 0.07), however this difference was not statistically significant. Conclusions The PSMRF program shows a significant increase in enrollment, as well as positive associations with indicators of success in medical school and subsequent quality of residency program.

    The advanced endoscopy (AE) fellowship is a popular career track for graduating gastroenterology fellows. The number of fellows completing AE fellowships and the number of programs offering this training have increased in the past 5 years. Despite this, we suspect that the number of AE attending (staff physician) positions have decreased (relative to the number of fellows graduating), raising concerns regarding AE job market saturation. Our aim was to survey practicing gastroenterology physicians who completed an AE fellowship within the past 5 years regarding their current professional status. A 16-question survey was distributed using Research Electronic Data Capture by e-mail to practicing gastroenterologists who completed an AE fellowship between 2009 and 2013. The survey questions elicited information regarding demographics, professional status, and additional information. A total of 96 invitations were distributed via e-mail. Forty-one of 96 respondents (43%) replied to the survey. Approximately half of the respondents were employed in an academic practice, with the remainder in private practice (56% and 44%, respectively). Nearly half (46%) of the respondents found it "difficult" to find an AE position after training. Thirty-nine percent of private-practice endoscopists were performing > 200 ERCPs/year, whereas 65% were doing so in academic settings (P = .09). Fifty-six percent of respondents were in small practices (0 to 1 partner), with a significantly smaller group size in private versus academic practice (72% versus 43%, P = .021). Seventy-eight percent of respondents believed the AE job market was saturated; most responded that the AE job market was saturated in both academic and private practice (44%), whereas 34% believed the job market was saturated in academics only. Most respondents (73%) who were training AE fellows found it difficult to place them in AE attending positions. Respondents from academic practice found it significantly more

    Full Text Available Spectroscopic analysis of exoplanet hosts and the stellar sample from which they are drawn provides abundances and other properties that quantitively constrain models of planet formation. The program Spectroscopy Made Easy (SME determines stellar parameters by fitting observed spectra, though line lists must be selected wisely. For giant planets, it is now well established that stars with higher metallicity are more likely to have detected companions. Stellar metallicity does not seem to affect the formation and/or migration of detectable planets less massive than Neptune, especially when considering only the most massive planet in the system. In systems with at least one planet less than 10 times the mass of Earth, the mass of the most massive planet increases dramatically with host star metallicity. This may reflect metallicity dependent timescales for core formation, envelope accretion, and/or migration into the detection zone.

    The current dramatic increase of antibiotic resistant bacteria has revitalised the interest in bacteriophages as alternative antibacterial treatment. Meanwhile, the development of bioinformatics methods for analysing genomic data places high-throughput approaches for phage characterization within...... reach. Here, we present HostPhinder, a tool aimed at predicting the bacterial host of phages by examining the phage genome sequence. Using a reference database of 2196 phages with known hosts, HostPhinder predicts the host species of a query phage as the host of the most genomically similar reference...... phages. As a measure of genomic similarity the number of co-occurring k-mers (DNA sequences of length k) is used. Using an independent evaluation set, HostPhinder was able to correctly predict host genus and species for 81% and 74% of the phages respectively, giving predictions for more phages than BLAST...

    This study was conducted to investigate the effects of certain factors on the impedance signal in structural health monitoring. These factors were: the quality of the bond between the sensor and the host structure, and the characteristics of the host structure, such as geometry, mass, and material properties. This work was carried out to answer a set of questions, related to these factors, that were developed by the project team. The project team was comprised of Dr. Doug Ramers and Dr. Abdul Jalloh of the Summer Faculty Fellowship Program, Mr. Arnaldo Colon- Perez, a student intern from the University of Puerto Rico of Turabo, and Mr. John Lassiter and Mr. Bob Engberg of the Structural and Dynamics Test Group at NASA Marshall Space Flight Center (MSFC). This study was based on a review of the literature on structural health monitoring to investigate the factors referred to above because there was not enough time to plan and conduct the appropriate tests at MSFC during the tenure of the Summer Faculty Fellowship Program project members. The surveyed literature documents works on structural health monitoring that were based on laboratory tests that were conducted using bolted trusses and other civil engineering type structures for the most part. These are not the typical types of structures used in designing and building NASA s space vehicles and systems. It was therefore recommended that tests be conducted using NASA type structures, such as pressure vessels, to validate the observations made in this report.

    We report on the magnetic, magnetotransport and structural characterization of (Ca{sub 1-y}Nd{sub y}){sub 2}Fe{sub 1+x}Mo{sub 1-x}O{sub 6} (x<0.5) ferromagnetic double perovskites. It is found that the presence of an excess (x>0) of Fe ions in the metallic sublattice produces a remarkable increase, by more than 90 K, of the Curie temperature. Moessbauer spectroscopy data indicate a reinforcement of the magnetic interactions. We argue that this dramatic enhancement of the ferromagnetic order is due to the strong antiferromagnetic superexchange coupling between near-neighbour Fe-Fe occupying regular and antisite positions in the structure. Moreover, the results indicate that the excess of magnetic ions (Fe) is essential to overcome the dilution effects caused by antisite defects.

    Structural, magnetic, and transport properties of perovskite La2/3Ca1/3Mn1-xSixO3 (x=0, 0.025, 0.05) have been studied. The incorporation of Si decreases the overall resistivity, but obviously increases the Curie temperature (Tc), metal-insulator transition temperature (Tp), and the magnetoresistance ratio MR (defined as [R(0)-R(H)]/R(O)) near room temperature. Comparing with La2/3Ca1/3MnO3, the Tc, Tp, and MR of the sample with x=0.05 increase by 30, 45K, and 20%, respectively. Lattice effects may play a more important role than the magnetic dilution in the case of low Si substitution.

Cette lecture montre cependant que les objectifs, les ressources et les stratégies des principaux acteurs concernés sont difficilement conciliables et que le système de relation qu’il induit n’est pas nécessairement en phase avec les finalités poursuivies.Marked by exceptional biodiversity and extreme human poverty, Madagascar is experiencing a rapid destruction of its natural resources, placing territory and its appropriation at the heart of development issues. From this perspective, this article will look at the development and implementation of a public policy, the Gestion LOcale SÉcurisée (GELOSE, for the local management of natural renewable resources. This regulation seeks to transfer the management of these resources from the government to local communities in the goal of protecting them more effectively. We will see, however, that the objectives, resources and strategies of the primary actors concerned are difficult to reconcile at best and that the relational system to which the policy gives rise is not necessarily in keeping with the goals being pursued.

    Full Text Available Residency training in obstetrics and gynecology is being challenged by increasingly stringent regulations and decreased operative experience. We sought to determine the perception of preparedness of incoming gynecologic oncology fellows for advanced surgical training in gynecologic oncology. An online survey was sent to gynecologic oncologists involved in fellowship training in the United States. They were asked to evaluate their most recent incoming clinical fellows in the domains of professionalism, level of independence/graduated responsibility, psychomotor ability, clinical evaluation and management, and academia and scholarship using a standard Likert-style scale. The response rate among attending physicians was 40% (n = 105/260 and 61% (n = 28/46 for program directors. Of those who participated, 49% reported that their incoming fellows could not independently perform a hysterectomy, 59% reported that they could not independently perform 30 min of a major procedure, 40% reported that they could not control bleeding, 40% reported that they could not recognize anatomy and tissue planes, and 58% reported that they could not dissect tissue planes. Fellows lacked an understanding of pathophysiology, treatment recommendations, and the ability to identify and treat critically ill patients. In the academic domain, respondents agreed that fellows were deficient in the areas of protocol design (54%, statistical analysis (54%, and manuscript writing (65%. These results suggest that general Ob/Gyn residency is ineffective in preparing fellows for advanced training in gynecologic oncology and should prompt a revision of the goals and objectives of resident education to correct these deficiencies.

    NASA accepted the Congressional mandate to manage the National Space Grant College and Fellowship Program (NSGC&FP) and announced the original competition for Space Grant awards in 1989. Currently, 52 independently governed Space Grant consortia administer programs in three areas of university and NASA concern: research, education, and public service. NASA funds have remained stable at $15 million since 1991, but the consortia have leveraged matching funds, including in-kind contributions, to approximately double the Space Grant awards. The number of affiliated Space Grant institutions has grown from 86 affiliates in 1990 to over 550 affiliates in 1996. Members include many of the finest colleges and universities in the nation, internationally competitive business and industrial partners, small businesses, state and local government agencies, private colleges, community colleges, medical colleges, and other nonprofit organizations. Though the program has been fully operational in all 52 consortia for less than five years, the benefits to the taxpayer have been significant. Space Grant faculty and students obtained funding for over 300 research proposals. Since 1990, the NSGC&FP has served close to 6500 citizens by providing tuition assistance. Among these 6500 were significant numbers of students from underrepresented groups in science and engineering. Space Grant consortia leveraged $16.5 million for precollege activities and administered over 1300 precollege projects that promote NASA-related science education. Space Grant precollege programs, serving both teachers and students, provide good examples of higher education faculty working well with local school systems. The consortia administered over 600 public service programs and leveraged approximately $4.5 million. Space Grant funds provided science and technology lectures, demonstrations, science exhibits, space-related periodicals, audio and video productions of NASA-related subjects, and have helped to

    Leadership is seen to be central to improving the quality of healthcare and existing research suggests that absence of leadership is related to poor quality and safety performance. Leadership training might therefore provide an important means through which to promote quality improvement and, more widely, performance within the healthcare environment. This article presents an evaluation of the Fellowships in Clinical Leadership Programme, which combines leadership training and quality improvement initiatives with the placement of temporary external clinical champions in Barking, Havering and Redbridge University Hospitals NHS Trust. We assessed impacts of the Programme on individual and organisational change, alongside core enablers and barriers for Programme success. Analyses drew on the principles of a theory-of-change-led realist evaluation, using logic modelling to specify the underlying causal mechanisms of the Programme. Data collection involved a stakeholder workshop, online questionnaires of programme participants, senior managers and support staff (n=114), and follow-up in-depth semi-structured interviews with a subsample of survey participants (n=15). We observed that the Programme had notable impacts at individual and organisational levels. Examples of individual impact included enhanced communication and negotiation skills or increased confidence as a result of multi-modal leadership training. At the organisational level, participants reported indications of behaviour change among staff, with evidence of spill-over effects to non-participants towards a greater focus on patient-centred care. Our findings suggest that there is potential for combined leadership training and quality improvement programmes to contribute to strengthening a culture of care quality in healthcare organisations. Our study provides useful insights into strategies seeking to achieve sustainable improvement in NHS organisations.

    This study follows two other ones about the same subject. No one could bring elements to the question of the exposure impact on the population having stayed in the school. The old pupils and personnel have been exposed to radiation doses higher to the limit values of public exposure especially before 1987. The scientific knowledge suggest that the eventual sanitary consequences are in the area of low risks. The lack of exhaustiveness in the inquiry realisation and the lack of statistical power did not allow to measure the sanitary impact of ionizing radiation exposure among the former pupils of the Marie Curie school of Nogent sur Marne.

HostPhinder predictions on phage draft genomes from the INTESTI phage cocktail corresponded well with the advertised targets of the cocktail. Our study indicates that for most phages genomic similarity correlates well with related bacterial hosts. HostPhinder is available as an interactive web service [1] and as a stand alone download from the Docker registry [2].

    The deleterious and sometimes fatal outcomes of bacterial infectious diseases are the net result of the interactions between the pathogen and the host, and the genetically tractable fruit fly, Drosophila melanogaster, has emerged as a valuable tool for modeling the pathogen–host interactions of a wide variety of bacteria. These studies have revealed that there is a remarkable conservation of bacterial pathogenesis and host defence mechanisms between higher host organisms and Drosophila. This review presents an in-depth discussion of the Drosophila immune response, the Drosophila killing model, and the use of the model to examine bacterial–host interactions. The recent introduction of the Drosophila model into the oral microbiology field is discussed, specifically the use of the model to examine Porphyromonas gingivalis–host interactions, and finally the potential uses of this powerful model system to further elucidate oral bacterial-host interactions are addressed.

    This presentation details the 21st Century Power Partnership's fellowship program accomplishments from 2016. This fellowship brought two fellows from South Africa's power utility, Eskom, to the U.S. Department of Energy's National Renewable Energy Laboratory. The fellows spent two weeks working to improve the fidelity of Eskom's PLEXOS long-term and short-term models, which are used in long-term generation planning exercises and capacity adequacy assessments. The fellows returned to Eksom equipped with a new suite of tools and skills to enhance Eksom's PLEXOS modeling capabilities.
