    Full Text Available Hardin-Simmons University was given two remarkable collections of rare Bibles and a Sefer Torah with the expressed desire of the donors for the collections to be shared with students, faculty and other constituencies of the university's Richardson Library. The library has tried to fulfill this request while attempting to preserve these treasures for future generations. As small university, without a trained archivist or preservationist, we have utilized resources outside our library and contiue to pursue sources to assist us in the maintenance of these special collections while still engaging them in the educational process.

    In the Closing Remarks at the Symposium on 'Frontiers in Bioorganic Chemistry' (Friday, February 6, 2009, Pharmacenter, University of Basel) in honour of Daniel Bellus, his arrival in Zürich in fall 1967 and especially his postdoctoral work at the Laboratorium für Organische Chemie at the Eidgenössische Technische Hochschule (ETH) in Zürich throughout the year 1967/68 were mentioned. In his most remarkable paper (published in 1969 in Helv. Chim. Acta), the photochemistry of the alpha,beta-unsaturated cyclohexenones O-acetyl-testosterone and 10-methy-delta1,9-octalon-(2) is described in detail. Change of solvent leads to lowering or increasing of the n,pi*- and (pi,pi*)-triplet energies, resulting in a crossing of the two energy levels. Personal remarks on Daniel Bellus and warmest thanks to him, to Profs. Beat Ernst and Bernd Giese (the organizers of the symposium) and to all the speakers concluded this most special event.

  7. Some progress towards ''universal'' effective interactions

    International Nuclear Information System (INIS)

    Gomez, J.M.G.

    1983-01-01

    The approximation methods introduced to treat the nuclear many-body problem usually imply that the appropriate nuclear force is an effective interaction, different from the free nucleon-nucleon interaction. An effective interaction is thus intimately related to a given nuclear model and its scope is generally confined to the description of a limited number of nuclei or nuclear states. However, in recent years there has been some progress towards ''universal'' effective nucleon-nucleon interactions, in the sense that they may be reasonably suitable to describe bulk properties of nuclear ground states throughout the periodic table and also properties of excited states. The authors conclude that a finite-range density-dependent effective interaction of the Gogny's type is capable of describing a large number of static and dynamical nuclear properties throughout the periodic table, including open-shell nuclei. Hopefully it may provide clues for the definition of some ''universal'' effective force

    Influenza virus (IFV) infection causes serious health problems and heavy financial burdens each year worldwide. The classical inactivated influenza virus vaccine (IIVV) and live attenuated influenza vaccine (LAIV) must be updated regularly to match the new strains that evolve due to antigenic drift and antigenic shift. However, with the discovery of broadly neutralizing antibodies that recognize conserved antigens, and the CD8(+) T cell responses targeting viral internal proteins nucleoprotein (NP), matrix protein 1 (M1) and polymerase basic 1 (PB1), it is possible to develop a universal influenza vaccine based on the conserved hemagglutinin (HA) stem, NP, and matrix proteins. Recombinant adenovirus (rAd) is an ideal influenza vaccine vector because it has an ideal stability and safety profile, induces balanced humoral and cell-mediated immune responses due to activation of innate immunity, provides 'self-adjuvanting' activity, can mimic natural IFV infection, and confers seamless protection against mucosal pathogens. Moreover, this vector can be developed as a low-cost, rapid-response vaccine that can be quickly manufactured. Therefore, an adenovirus vector encoding conserved influenza antigens holds promise in the development of a universal influenza vaccine. This review will summarize the progress in adenovirus-vectored universal flu vaccines and discuss future novel approaches.

    Canada is participating in the international cooperative forum on system research for two designs (supercritical water-cooled reactor, SCWR, and Very High Temperature Reactor, VHTR) of the Gen-IV nuclear reactor. The forum is referred to as the Generation-IV International Forum (or GIF). The Canadian effort focuses mainly on the SCWR. Among various GIF participants, Canada is the leader of this design and has interest mainly on the pressure-tube type reactor, which is a natural extension of the existing CANDU reactor. Several critical research areas (such as material, chemistry, thermalhydraulics, instability, critical flow, etc.) have been identified in the system-research plan for supporting the SCWR design. Collaborative projects have been established between AECL and universities in China to expedite the CANDU SCWR design. These projects focus on research areas beyond the current scope of the AECL and the NSERC/NRCan/AECL collaborative research and development (CRD) project. AECL supports these projects directly and is contributing (in-kind) the results and findings to the Canadian national program. The collaboration between AECL and Chinese universities began in 2007 July. Most projects cover the duration of three years. The Chinese universities submit their annual progress reports each year prior to the project renewal. The objective of this report is to summarize the progress on collaborative projects between AECL and Chinese universities (namely the Tsinghua University, Shanghai Jiaotong University, and Xi'an Jiaotong University) over the duration of 2008 July to 2009 June.

    2014-01-01

    Full Text Available Background Progress testing is a method of assessing longitudinal progress of students using a single best answer format pitched at the standard of a newly graduated doctor. Aim To evaluate the results of the first year of summative progress testing at the University of Auckland for Years 2 and 4 in 2013. SUBJECTS: Two cohorts of medical students from Years 2 and 4 of the Medical Program. Methods A survey was administered to all involved students. Open text feedback was also sought. Psychometric data were collected on test performance, and indices of reliability and validity were calculated. Results The three tests showed increased mean scores over time. Reliability of the assessments was uniformly high. There was good concurrent validity. Students believe that progress testing assists in integrating science with clinical knowledge and improve learning. Year 4 students reported improved knowledge retention and deeper understanding. Conclusion Progress testing has been successfully introduced into the Faculty for two separate year cohorts and results have met expectations. Other year cohorts will be added incrementally. Recommendation Key success factors for introducing progress testing are partnership with an experienced university, multiple and iterative briefings with staff and students as well as demonstrating the usefulness of progress testing by providing students with detailed feedback on performance.

    Science.gov (United States)

    1998-01-01

    This article describes the progress made in reducing fertility in Bangladesh, and government goals for meeting future challenges. Fertility declined from 7.0 to 3.3 children/woman during 1975-96. Contraceptive prevalence increased from 3% to about 50% during 1971-96. Population in 1997, was about 123 million. Population is expected to increase to about 210 million by the year 2020. Bangladesh is one of the most densely populated countries. About 50% of the female population are unmarried and aged under 20 years. Adolescent fertility is very high at 171 births/1000 girls aged 15-19 years. About 30% of adolescents are mothers, and another 6% are pregnant with their first child. Female age at marriage increased to 18 years. The contraceptive prevalence rate among adolescents is only 25%. 20% of total population live in urban areas. Infant, child, and maternal mortality rates are still high. The long-term goal of the government is to reduce fertility to a 2-child family norm by 2002. The plan of action focuses on improved quality of care, intensifying program efforts in low performing areas, focusing on critical underserved groups, implementing family planning services in the Health Directorate, improving performance reporting and follow-up, strengthening IEC and community mobilization, carrying out critical training, enhancing collaboration between governmental and nongovernmental groups, and improving maternal, child, and reproductive health. A National Committee for the Implementation of the aforementioned Program of Action of the ICPD was set up in October 1994.

The workshop attracted around 40 people from the Ministry of Education, Turkish Satellite Corporation (TURKSAT, Anadolu University, and various academic staff from different universities in Ankara. All together, there were 8 presentations each followed by a discussion. Main contributors, their brief CV’s, and the workshop program are included in the preceding part of this document.Here, I would try to put together various important points and remarks made by the speakers according to the order in the program.The first talk was presented by Professor Tapio Varis, Acting President of GUS, about the Global University System (GUS. He started his talk by reviewing the trends of the 21st Century in terms of education and technology. He emphasized the need to humanize the globalization process by adding “solidarity”, “sprit of caring for”, and “sharing with others”. It was stated that, content development, especially for educational purposes, is a difficult issue in achieving this process. Professor Varis, declared “digital literacy” as being a right for all. He mentioned “phonetic alphabet” as a tool to alleviate the problems associated with the communication among different nationalities. He mentioned the need to exchange ideas, opinions and experience to create a successful working environment and stressed the importance of cultural issues such as quality assurance, translation and assessment. He also talked about open courseware, “education for all”, offered by MIT and UNESCO. Finally, Professor Varis summarized the mission of GUS as to offer a global quality education (described as a renaissance education program for developing countries and/or regions by taking into account cultural sensitivities.The second talk was presented by Professor Takeshi Utsumi about the Global Collaborative

  18. Editorial - a remark you made

    Full Text Available ”A remark you made” is the title of a wonderful tune by the famous jazz-rock group “Weather Report”, issued on the influential “Heavy weather” LP some 30 years ago. In an age where planning and rationalizing is the main issue in most contexts, whether it’s a matter of studying, teaching, doing research or using a diet, “A remark you made” is a symbol of attending to the unplanned, unforeseen and often, unwanted. In most accounts on cognitive development one is overtly focused on the manageable, on the predictable and expected, and not so attentive to the opposite. “A remark you made” makes us think again and reconsider what might be of value, in what we otherwise might neglect. A remark made by Terry Anderson at a conference last year (2006 was rather telling. Anderson is the renown distance educator from Athabasca University, Alberta Canada, and editor of our fellow e-journal “The International Review of Research in Open and Distance Learning”. I recite it here totally from my own memory, and I have never approached him to have it verified, falsified or commented. That doesn’t matter in this context. Standing on the podium, he lowered his voice and asked if any Danes were present in the room. There weren’t! Then he explained that his argument might be presented differently with Danes present: “You see – Danes seem to think that learning alone is no longer possible!” That remark caused quite a good laugh, not the least because any comment – good or bad – about fellow Scandinavians generally is considered to be a good joke. But it was also a comment on how not only distance education, or open and flexible learning, but learning theory in general is driven by the sociocultural learning theory, - and according to Anderson, particularly so in Denmark! Our first contribution in this issue is about the theory of media theory developed by one of our editors: Lars Qvortrup. Lars is now the rector of the Danish

    Full Text Available Background: The Association of Southeast Asian Nations (ASEAN is characterized by much diversity in terms of geography, society, economic development, and health outcomes. The health systems as well as healthcare structure and provisions vary considerably. Consequently, the progress toward Universal Health Coverage (UHC in these countries also varies. This paper aims to describe the progress toward UHC in the ASEAN countries and discuss how regional integration could influence UHC. Design: Data reported in this paper were obtained from published literature, reports, and gray literature available in the ASEAN countries. We used both online and manual search methods to gather the information and ‘snowball’ further data. Results: We found that, in general, ASEAN countries have made good progress toward UHC, partly due to relatively sustained political commitments to endorse UHC in these countries. However, all the countries in ASEAN are facing several common barriers to achieving UHC, namely 1 financial constraints, including low levels of overall and government spending on health; 2 supply side constraints, including inadequate numbers and densities of health workers; and 3 the ongoing epidemiological transition at different stages characterized by increasing burdens of non-communicable diseases, persisting infectious diseases, and reemergence of potentially pandemic infectious diseases. The ASEAN Economic Community's (AEC goal of regional economic integration and a single market by 2015 presents both opportunities and challenges for UHC. Healthcare services have become more available but health and healthcare inequities will likely worsen as better-off citizens of member states might receive more benefits from the liberalization of trade policy in health, either via regional outmigration of health workers or intra-country health worker movement toward private hospitals, which tend to be located in urban areas.

    Hawking's area theorem is a fundamental result in black hole theory that is universally associated with the null energy condition. That this condition can be weakened is illustrated by the formulation of a strengthened version of the theorem based on an energy condition that allows for violations of the null energy condition. With the semi-classical context in mind, some brief remarks pertaining to the suitability of the area theorem and its energy condition are made.

    The vigorous development of silicon photonics makes a silicon-based light source essential for optoelectronics' integration. Bonding of III-V/Si hybrid laser has developed rapidly in the last ten years. In the tireless efforts of researchers, we are privileged to see these bonding methods, such as direct bonding, medium adhesive bonding and low temperature eutectic bonding. They have been developed and applied to the research and fabrication of III-V/Si hybrid lasers. Some research groups have made remarkable progress. Tanabe Katsuaki of Tokyo University successfully implemented a silicon-based InAs/GaAs quantum dot laser with direct bonding method in 2012. They have bonded the InAs/GaAs quantum dot laser to the silicon substrate and the silicon ridge waveguide, respectively. The threshold current of the device is as low as 200 A/cm2. Stevan Stanković and Sui Shaoshuai successfully produced a variety of hybrid III-V/Si laser with the method of BCB bonding, respectively. BCB has high light transmittance and it can provide high bonding strength. Researchers of Tokyo University and Peking University have realized III-V/Si hybrid lasers with metal bonding method. We describe the progress in the fabrication of III-V/Si hybrid lasers with bonding methods by various research groups in recent years. The advantages and disadvantages of these methods are presented. We also introduce the progress of the growth of III-V epitaxial layer on silicon substrate, which is also a promising method to realize silicon-based light source. I hope that readers can have a general understanding of this field from this article and we can attract more researchers to focus on the study in this field.

Many have been assessed for timely recognition, early treatment, and adequate follow-up for a variety of pathologies. Biomarker sensitivity has improved considerably over the last years but specificity remains poor, in particular when two “marker-sensitive” conditions overlap in one patient. Biomarker research holds an enormous potential for diagnostic and prognostic purposes in postoperative and critically ill patients who present varying degrees of inflammation, infection, and concomitant (subacute organ dysfunction or failure. Despite a remarkable progress in development and testing, biomarkers are not yet ready for routine use at the bedside. Keywords: biomarkers, acute kidney injury, sepsis, ARDS

    Kreisel, E.

    1976-01-01

    It is shown that one can get spontaneous particle creation in an empty Minkowski-space, if one defines particle-number operator and Hilbert space in a similar way as in publications about particle creation in an expanding universe. Accordingly spontaneous particle creation does not originate in the gravitational field, but is connected with the non-uniqueness of the notion 'particle' and the chosen time-dependent particle- number operator.

    2013-12-01

    Full Text Available Since the Environmental Science program at Linköping University started 1998 the author has been liaison librarian. The program is a three-year candidate program with approximately 60 students enrolled per year. Information literacy is of vital importance for the teachers and the students. Collaboration between the liaison librarian, the teachers and the administrator is the fundament. During the years a curriculum for Information literacy has evolved. The initiative for the evolvement comes from both librarian and teachers. The program consists today of fifteen different parts with education in information literacy with a progression during the three-year program. Special concern is given to progression, learning design, learning environments and quality development. An important part is appendixes in connection to the student essay. The appendixes consist of reflections on the search of information for the essay in order to make the students more conscious about their Information Literacy processes.

    Full Text Available ABSTRACT In its French-Brazilian version, the Teletandem Brazil project enables students from the University of Lille 3 (France and from the State University of São Paulo (Unesp, Brazil, to take part in online exchanges, based on the principles of autonomy and reciprocity. In this work, we will present some preliminary remarks on the construction of cultural identity representations by the students who took part in the project, from 2006 to 2012, the specificity of the exchanges we analyze being that most of the French students involved in them are third generation Portuguese. We will examine the consequences of the introduction of a third culture within exchanges which, linguistically speaking, are bilateral. The French students are often experiencing conflicting feelings toward Brazil and, similarly, the Brazilian students may have conflicting feelings towards Portugal and France. Our preliminary results show that the most successful linguistic exchanges occur when students face their own cultural identity with no feeling of superiority or inferiority.

  19. Improving equity in health care financing in China during the progression towards Universal Health Coverage.

    Chen, Mingsheng; Palmer, Andrew J; Si, Lei

    2017-12-29

    China is reforming the way it finances health care as it moves towards Universal Health Coverage (UHC) after the failure of market-oriented mechanisms for health care. Improving financing equity is a major policy goal of health care system during the progression towards universal coverage. We used progressivity analysis and dominance test to evaluate the financing channels of general taxation, pubic health insurance, and out-of-pocket (OOP) payments. In 2012 a survey of 8854 individuals in 3008 households recorded the socioeconomic and demographic status, and health care payments of those households. The overall Kakwani index (KI) of China's health care financing system is 0.0444. For general tax KI was -0.0241 (95% confidence interval (CI): -0.0315 to -0.0166). The indices for public health schemes (Urban Employee Basic Medical Insurance, Urban Resident's Basic Medical Insurance, New Rural Cooperative Medical Scheme) were respectively 0.1301 (95% CI: 0.1008 to 0.1594), -0.1737 (95% CI: -0.2166 to -0.1308), and -0.5598 (95% CI: -0.5830 to -0.5365); and for OOP payments KI was 0.0896 (95%CI: 0.0345 to 0.1447). OOP payments are still the dominant part of China's health care finance system. China's health care financing system is not really equitable. Reducing the proportion of indirect taxes would considerably improve health care financing equity. The flat-rate contribution mechanism is not recommended for use in public health insurance schemes, and more attention should be given to optimizing benefit packages during China's progression towards UHC.

    Posey-Eddy, F.; McConnell, R. D.

    2002-08-01

    This report details the DOE/NREL Historically Black College and University (HBCU) Photovoltaic Research Associates Program, a small but remarkable program that directly affected dozens of minority undergraduate students in ways that changed many of their lives. The progress and accomplishments of undergraduates within the nine participating universities were monitored and assessed through their presentations at an annual NREL-sponsored HBCU conference. Although the funding was small, typically $400,000 per year, the money made a significant impact. The best students sometimes went on to the nation's top graduate schools (e.g., MIT) or important management positions in large companies. Other students had opportunities to learn how renewable energy could positively affect their lives and their neighbors' lives. A few were lucky enough to install photovoltaic lighting and water-pumping systems in Africa, and to see and feel firsthand the technical and emotional benefits of this technology for families and villages. Two of the schools, Texas Southern University and Central State University, were particularly successful in leveraging their DOE/NREL funding to obtain additional funding for expanded programs.

    2011-01-01

    An important era in particle physics is coming to an end: the US Department of Energy announced on Monday that it will not fund an extension to Tevatron running beyond 2011. It is a poignant moment for particle physics as we prepare to bid farewell to a machine that has changed our view of the Universe, and played a significant role in paving the way for the new era that is opening up with the LHC.   The Tevatron has been at the high-energy frontier of particle physics for over a quarter of a century. That’s a remarkable achievement by any account, and the physics results are there to prove it. As well as bringing us the discovery of the top quark in 1995, the Tevatron’s experiments have provided vitally important precision measurements covering the full spectrum of Standard Model physics, not to mention hints of what may lie beyond. With several months of running still to come, it would be a foolish gambler who bet against further new physics emerging before the Teva...

  6. Remarks on stellar clusters

    International Nuclear Information System (INIS)

    Teller, E.

    1985-01-01

    In the following, a few simple remarks on the evolution and properties of stellar clusters will be collected. In particular, globular clusters will be considered. Though details of such clusters are often not known, a few questions can be clarified with the help of primitive arguments. These are:- why are spherical clusters spherical, why do they have high densities, why do they consist of approximately a million stars, how may a black hole of great mass form within them, may they be the origin of gamma-ray bursts, may their invisible remnants account for the missing mass of our galaxy. The available data do not warrant a detailed evaluation. However, it is remarkable that exceedingly simple models can shed some light on the questions enumerated above. (author)

  7. Seven remarkable days

    CERN Document Server

    This has been a truly remarkable seven days for CERN. Things have moved so fast that it has sometimes been hard to separate fact from fiction – all the more so since facts have often seemed too good to be true. It’s been a week of many firsts. Monday was the first time we’ve had two captured beams in the LHC. It’s the first time the LHC has functioned as a particle accelerator, boosting particles to the highest beam energy so far achieved at CERN. And it’s been a week in which we’ve seen the highest energy proton-proton collisions ever produced at CERN: our last hadron collider, the SPS was a proton-antiproton collider, a technically simpler machine than the LHC. This week’s successes are all the more remarkable precisely because of the complexity of the LHC. Unlike the SPS collider, it is two accelerators not one, making the job of commissioning nearly twice as difficult. I’d like to express my heartfelt thanks and congra...

    1981-01-01

    This introduction to contemporary ideas in cosmology differs from other books on the 'expanding Universe' in its emphasis on physical cosmology and on the physical basis of the general theory of relativity. It is considered that the remarkable degree of isotropy, rather than the expansion, can be regarded as the central observational feature of the Universe. The various theories and ideas in 'big-bang' cosmology are discussed, providing an insight into current problems. Chapter headings are: quality of matter; expanding Universe; quality of radiation; quantity of matter; general theory of relativity; cosmological models; cosmological tests; matter and radiation; limits of isotropy; why is the Universe isotropic; singularities; evolution of structure.

    Full Text Available Considering the fact that students studying various fields of Study will have the responsibility to create, maintain and improve society’s level of health, they should be cared for with precision so they can perform and play their role as an educated and expert work force. this is due to the fact that getting accepted in university is a very sensitive period in lives of efficient workforce and active youth in each country, therefore, present study determines the relation between general health and educational progress among paramedical faculty’s Students of Tehran Medical University. Method: present research has a descriptive-analytic nature and was executed in a time period during winter of 2016. the target society included all students of paramedical faculty and required data was gathered by an adults’ health function literacy questionnaire and general health was also gathered by means of general health questionnaire. in order to present descriptive results of percentage and median and to study and analyses quantitative data, parametric statistical tests was used for normal data and in case there were not normal, unparametric tests were applied. Findings: Results of present study showed that there is a positive significant relation between general health and educational progress (r=01 / 0 p <،28 / 0. Still, no significant relation was observed between general health and health literacy (r= 0.038, p=0.569. Conclusion: In studying general health aspects with health literacy and educational health motivation, all aspects of general health (physical aspect, anxiety aspect, social function aspect, depression aspect showed a direct and significant relation with educational progress but presented no significant relation with health literacy. Still, we could observe a positive effect on educational progress and health literacy by trying to improve any of general health factors. In other words, we could use organizational capitals to improve

    1987-01-01

    General opening remarks to a conference on the effects of low-level radiation on man, exploring particularly areas where disagreements have most frequently been voiced. The author comments on two approaches: a) the study, stepwise of putative cause and effect chains, using models which are tested by comparing calculated and observed effects. b) the epidemiological approach by extensive correlative study of cause, correlations and effect. Attention is drawn to the confidence to be accorded to any quantitative theory supported by both approaches, and the need for further analysis if the approaches give different indications. (U.K.)

  13. The holographic universe

    Talbot, Michael

    1991-01-01

    'There is evidence to suggest that our world and everything in it - from snowflakes to maple trees to falling stars and spinning electrons - are only ghostly images, projections from a level of reality literally beyond both space and time.' This is the astonishing idea behind the holographic theory of the universe, pioneered by two eminent thinkers: physicist David Bohm, a former protege of Albert Einstein, and quantum physicist Karl Pribram. The holographic theory of the universe encompasses consciousness and reality as we know them, but can also explain such hitherto unexplained phenomena as telepathy, out-of-body experiences and even miraculous healing. In this remarkable book, Michael Talbot reveals the extraordinary depth and power of the holographic theory of the universe, illustrating how it makes sense of the entire range of experiences within our universe - and in other universes beyond our own.

    1985-01-01

    The author's remarks are directed primarily at proposals that have been made that would substantially tort law with respect to radiation claims in order to ease the ability of claimants to recovery damages from defendants. The change would be based upon what had been assumed to be a ''scientific'' means of measuring the ''probability'' that exposure to ionizing radiation was the case of a cancer in a particular claimant. The remarks are divided into three parts: a summary description of the nuclear insurance pools, including the tort radiation claims filed against the pools; and a brief description of claims against the Federal Government and its contractors; an examination of the elementary principles of tort law, and an outline of the threat that has developed that would transform it into a hybrid social benefits program; and comment on the danger to the integrity of science when it is injected into the legislative process

This contract supports broadly based experimental work in intermediate energy nuclear physics. The program includes pion-nucleon studies at TRIUMF and LAMPF, inelastic pion scattering and charge exchange reactions at LAMPF, and nucleon charge exchange at LAMPF/NTOF. The first results of spin-transfer observables in the isovector (rvec p,rvec n) reaction are included in this report. Our data confirm the tentative result from (rvec p,rvec p') reactions that the nuclear isovector spin response shows neither longitudinal enhancement nor transverse queching. Our program in quasifree scattering of high energy pions shows solid evidence of isoscalar enhancement of the nuclear nonspin response. We include several comparisons of the quasifree scattering of different probes. Results from our efforts in the design of accelerator RF cavities are also included in this report

    The workshop has covered in a very interesting and complete way the basic physics issues to be addressed by the complementary facilities, in Canada and Japan, intended to explore the intensity-frontier of strong-interaction physics. Japan has its new KEK facilities and its future Japanese Hadron Project (JHP): Canada has its present TRIUMF laboratory and its future KAON Factory. Both JHP and KAON appear very near to final construction approval. The possibilities are very great for new joint programs between the two countries which can lead the world in the new strong interaction physics. These concluding remarks describe the general science basis and particularly the models for the internationalization of science needed to make these new collaborations thrive

  1. Universal properties of relaxation and diffusion in condensed matter

    International Nuclear Information System (INIS)

    Ngai K L

    2017-01-01

    By and large the research communities today are not fully aware of the remarkable universality in the dynamic properties of many-body relaxation/diffusion processes manifested in experiments and simulations on condensed matter with diverse chemical compositions and physical structures. I shall demonstrate the universality first from the dynamic processes in glass-forming systems. This is reinforced by strikingly similar properties of different processes in contrasting interacting systems all having nothing to do with glass transition. The examples given here include glass-forming systems of diverse chemical compositions and physical structures, conductivity relaxation of ionic conductors (liquid, glassy, and crystalline), translation and orientation ordered phase of rigid molecule, and polymer chain dynamics. Universality is also found in the change of dynamics when dimension is reduced to nanometer size in widely different systems. The remarkable universality indicates that many-body relaxation/diffusion is governed by fundamental physics to be unveiled. One candidate is classical chaos on which the coupling model is based, Universal properties predicted by this model are in accord with diverse experiments and simulations. (paper)

    Holz, D E; Orland, H; Zee, A

    2003-01-01

    A non-Hermitian random matrix model proposed a few years ago has a remarkably intricate spectrum. Various attempts have been made to understand the spectrum, but even its dimension is not known. Using the Dyson-Schmidt equation, we show that the spectrum consists of a non-denumerable set of lines in the complex plane. Each line is the support of the spectrum of a periodic Hamiltonian, obtained by the infinite repetition of any finite sequence of the disorder variables. Our approach is based on the 'theory of words'. We make a complete study of all four-letter words. The spectrum is complicated because our matrix contains everything that will ever be written in the history of the universe, including this particular paper

    Amber Wigmore-Álvarez

    2014-04-01

    Full Text Available Sustainability and social responsibility (SR have emerged as a new way of managing all types of organizations. It is necessary that the resulting policy be integrated transversely in the control processes. The environment is especially demanding of higher education institutions (HEIs and universities when it comes to behaving in a socially responsible manner due to their great influence in society. Many universities have adhered to the United Nations Global Compact (UNGC principles to prove their commitment and gain legitimacy. The Communication on Progress (COP is a management tool that helps to understand the level of implementation of the principles. Furthermore, COP analysis aids in establishing a process of continuous improvement in the management of the impacts that institutions have on their stakeholders. The aim of this study was to analyze the Spanish universities that have joined the Global Compact. Through a descriptive methodology, we identified the aspects that reflect this commitment and how this is integrated into their operational and educational processes. The results have shown that it is necessary to promote the integration of different international initiatives to guide the SR of universities. There are deficiencies in their SR management systems that prevent them from being more transparent, and it was found that in some cases, they are not aware of the implications the commitment can have in developed countries.

    Achieving universal health coverage is one of the key targets in the newly adopted Sustainable Development Goals of the United Nations. To investigate progress toward universal health coverage in 5 South Asian countries and assess inequalities in health services and financial risk protection indicators. In a population-based study, nationally representative household (335 373 households) survey data from Afghanistan (2014 and 2015), Bangladesh (2010 and 2014), India (2012 and 2014), Nepal (2014 and 2015), and Pakistan (2014) were used to calculate relative indices of health coverage, financial risk protection, and inequality in coverage among wealth quintiles. The study was conducted from June 2012 to February 2016. Three dimensions of universal health coverage were assessed: access to basic services, financial risk protection, and equity. Composite and indicator-specific coverage rates, stratified by wealth quintiles, were then estimated. Slope and relative index of inequality were used to assess inequalities in service and financial indicators. Access to basic care varied substantially across all South Asian countries, with mean rates of overall prevention coverage and treatment coverage of 53.0% (95% CI, 42.2%-63.6%) and 51.2% (95% CI, 45.2%-57.1%) in Afghanistan, 76.5% (95% CI, 61.0%-89.0%) and 44.8% (95% CI, 37.1%-52.5%) in Bangladesh, 74.2% (95% CI, 57.0%-88.1%) and 83.5% (95% CI, 54.4%-99.1%) in India, 76.8% (95% CI, 66.5%-85.7%) and 57.8% (95% CI, 50.1%-65.4%) in Nepal, and 69.8% (95% CI, 58.3%-80.2%) and 50.4% (95% CI, 37.1%-63.6%) in Pakistan. Financial risk protection was generally low, with 15.3% (95% CI, 14.7%-16.0%) of respondents in Afghanistan, 15.8% (95% CI, 14.9%-16.8%) in Bangladesh, 17.9% (95% CI, 17.7%-18.2%) in India, 11.8% (95% CI, 11.8%-11.9%) in Nepal, and 4.4% (95% CI, 4.0%-4.9%) in Pakistan reporting incurred catastrophic payments due to health care costs.

    Full Text Available På baggrund af en kvalitativ interviewundersøgelse af undervisere ved Aarhus Universitet lavet i 2012, tematiserer artiklen, hvordan undervisere udvikler deres faglige og pædagogiske kompetencer i forhold til at kunne skabe progression inden for innovation og entreprenørskab forstået enten som didaktik, arbejdsformer i faglige forløb eller som fag på universitetet. I arbejdet med progression er det en udfordring at integrere de nye faglige dimensioner i det kernefaglige felt. Den seneste model for progression inden for innovation og entreprenør-skab siger, at det er den lærendes generelle erfaringsniveau, der er den afgørende progressionsskabende faktor (Progressionsmodellen, Fonden for Entreprenørskab, 2013b. Samtidig skelner international forskning inden for studiekompetenceområdet mellem niveauer, hvor indlejret viden er det mest avancerede kompetenceniveau (Barrie, 2002.Ifølge progressionsmodellen og den nævnte kompetenceforskning er erfaring og dybt integreret læring altså centrale dimensioner i progression. Men hvad er underviserens rolle heri? Underviserens professionelle udviklingsarbejde forekommer at være underbelyst i forhold til, at underviseren er den legitime garant for integrationen af nye faglige dimensioner og for den studerendes kompetenceniveau. Interviewundersøgelsen forholder sig til spørgsmålet om progression gennem de deltagende underviseres beskrivelse af betydningslag i entreprenørskabsbegrebet koblet til de praksisformer i undervisningen, der knytter sig hertil samt et indblik i undervisernes refleksioner over deres kompetenceudviklingsprocesser. Artiklens bidrag til progression er at se underviserens motivation og kompetenceudvikling som forudsætninger herfor.     Based on a qualitative study of five teachers in the Faculty of Arts at Aarhus University that took place during 2012, the article thematizes how teachers develop their professional and educational qualifications in innovation and

  9. The Social Interplay of Disciplinarity and Interdisciplinarity. Some Introductory Remarks

    2006-12-01

    Full Text Available Social Science Education as a subject field in schools is an intrinsic pluridisciplinary feature, whatever disciplines are included, however it may be organised and wherever it may be institutionalised. Civic education, economic education, social education and historical education each comprise several academic disciplines even if they are thought to be completely independent subjects. From the start on, disciplinarity and interdisciplinarity are on the agenda for any subject related to social science education and are one of its main problems. For these introductory remarks interdisciplinarity can be simply defined as relating two or more academic disciplines or school subjects to each other if this is done in a purposeful, systematic, explicit and reflective way. The overarching goal is to improve education that is to enhance students' understandings of the worlds and their abilities to act within and towards them. A relationship between disciplines or subjects which misses one or more of the four characteristics can be called pluridisciplinary or multidisciplinary (cf. Audigier 2006. In the following I first want to discuss some aspects of disciplinarity and interdisciplinarity at schools and at universities and the weakness of interdisciplinarity. I sketch some social science based ideas on the interrelationship between the subject structure of the academic world and the world of schools (3. and of some tendency to commonalities or even unification of social sciences and related competencies (4..

  10. Achieving equity within universal health coverage: a narrative review of progress and resources for measuring success.

    Rodney, Anna M; Hill, Peter S

    2014-10-10

    Equity should be implicit within universal health coverage (UHC) however, emerging evidence is showing that without adequate focus on measurement of equity, vulnerable populations may continue to receive inadequate or inferior health care. This study undertakes a narrative review which aims to: (i) elucidate how equity is contextualised and measured within UHC, and (ii) describe tools, resources and lessons which will assist decision makers to plan and implement UHC programmes which ensure equity for all. A narrative review of peer-reviewed literature published in English between 2005 and 2013, retrieved from PubMed via the search words, 'universal health coverage/care' and 'equity/inequity' was performed. Websites of key global health organizations were also searched for relevant grey literature. Papers were excluded if they failed to focus on equity (of access, financial risk protection or health outcomes) as well as focusing on one of the following: (i) the impact of UHC programmes, policies or interventions on equity (ii) indicators, measurement, monitoring and/or evaluation of equity within UHC, or (iii) tools or resources to assist with measurement. Eighteen journal articles consisting mostly of secondary analysis of country data and qualitative case studies in the form of commentaries/reviews, and 13 items of grey literature, consisting largely of reports from working groups and expert meetings focusing on defining, understanding and measuring inequity in UHC (including recent drafts of global/country monitoring frameworks) were included. The literature advocates for progressive universalism addressing monetary and non-monetary barriers to access and strengthening existing health systems. This however relies on countries being effectively able to identify and reach disadvantaged populations and estimate unmet need. Countries should assess the new WHO/WB-proposed framework for its ability to adequately track the progress of disadvantaged populations in terms

  11. Evasion of Cell Senescence Leads to Medulloblastoma Progression

    Directory of Open Access Journals (Sweden)

    Lukas Tamayo-Orrego

    2016-03-01

    Full Text Available How brain tumors progress from precancerous lesions to advanced cancers is not well understood. Using Ptch1+/− mice to study medulloblastoma progression, we found that Ptch1 loss of heterozygosity (LOH is an early event that is associated with high levels of cell senescence in preneoplasia. In contrast, advanced tumors have evaded senescence. Remarkably, we discovered that the majority of advanced medulloblastomas display either spontaneous, somatic p53 mutations or Cdkn2a locus inactivation. Consistent with senescence evasion, these p53 mutations are always subsequent to Ptch1 LOH. Introduction of a p53 mutation prevents senescence, accelerates tumor formation, and increases medulloblastoma incidence. Altogether, our results show that evasion of senescence associated with Ptch1 LOH allows progression to advanced tumors.

  16. “Think of it as a Challenge”: Problematizing Pedagogical Strategies for Progression When Assessing Web-based University Courses

    Directory of Open Access Journals (Sweden)

    Anette Svensson

    2015-09-01

    Full Text Available The aim of this study is to analyse how a taxonomy-based course design can support students’ qualitative learning processes in online university courses. The paper presents a case study based on two online courses in comparative literature in Swedish and English. A document analysis has been applied to analyse the empirical material, which includes the syllabuses, study guides, and examination assignments connected to the courses. Socio-cultural aspects of learning processes, assessment and feedback, course design using a taxonomic structure (SOLO, and a progressive theory of literary studies (Langer’s theories of envisionment function as a framework. The results show that the examination assignments aim to further the students’ educational processes from stage 2 to stage 5 of the SOLO-taxonomy and, at the same time, through Langer’s four stances. While the course structure has a positive effect on the students’ general as well as literary progress, there are some pedagogical challenges with online teaching in literature that are discussed. In addition, the examination assignments could have been used as ways to strengthen the students’ socio-cultural learning. Furthermore, with little alterations, the examination assignments, which were all used as means of summative assessment, could also have been used formatively to assess the students’ progress.

  18. Progress towards universal health coverage in BRICS: translating economic growth into better health.

    Science.gov (United States)

    Rao, Krishna D; Petrosyan, Varduhi; Araujo, Edson Correia; McIntyre, Diane

    2014-06-01

    Brazil, the Russian Federation, India, China and South Africa--the countries known as BRICS--represent some of the world's fastest growing large economies and nearly 40% of the world's population. Over the last two decades, BRICS have undertaken health-system reforms to make progress towards universal health coverage. This paper discusses three key aspects of these reforms: the role of government in financing health; the underlying motivation behind the reforms; and the value of the lessons learnt for non-BRICS countries. Although national governments have played a prominent role in the reforms, private financing constitutes a major share of health spending in BRICS. There is a reliance on direct expenditures in China and India and a substantial presence of private insurance in Brazil and South Africa. The Brazilian health reforms resulted from a political movement that made health a constitutional right, whereas those in China, India, the Russian Federation and South Africa were an attempt to improve the performance of the public system and reduce inequities in access. The move towards universal health coverage has been slow. In China and India, the reforms have not adequately addressed the issue of out-of-pocket payments. Negotiations between national and subnational entities have often been challenging but Brazil has been able to achieve good coordination between federal and state entities via a constitutional delineation of responsibility. In the Russian Federation, poor coordination has led to the fragmented pooling and inefficient use of resources. In mixed health systems it is essential to harness both public and private sector resources.

    2017-11-01

    Full Text Available The Faculty of Theology at the University of Pretoria went through a process of restructuring, resulting in the amalgamation of Dogmatics, Christian Ethics, Church History and Church Polity into one department under the name ‘Systematic and Historical Theology’. This contribution reflects only on the one aspect, namely Historical Theology. The point is made that a name change could not mean ‘business as usual’, but should be regarded as an opportunity to re-imagine the content and structure of Historical Theology. This is not an easy task. This contribution reflects on Historical Theology as theological discipline, the teaching content and how it could be relevant in Africa in the 21st century. It also has implications for restructuring the curriculum.

    1989-01-01

    Some remarks on the determination of the normal-superconductor phase boundary in random superconductive networks are made. A recently reported work by Soukoulis, Grest and Li which introduces weak links between nodes as these are removed in the site percolation problem is discussed. By the analysis of two simple geometries, it is shown that this procedure introduces spurious effects which mask the physical properties of the system. These affect in particular the field slope critical index and the sharpness of the normal-superconductor boundary. (Author)

    This special issue contains papers related to the 2009 Thomas Young Centre Workshop at University College London 'Accessing large length and time scales with accurate quantum methods', in celebration of Professor Michael Gillan's 65th birthday. Mike Gillan won the 2006 Institute of Physics Dirac Medal and Prize, the citation reading: 'For his contributions to the development of atomic-scale computer simulations, which have greatly extended their power and effectiveness over an immense range of applications'. This rightly highlights Mike's seminal work on materials modelling, but misses out some of the many other areas he has enriched. After taking his PhD at the Department of Theoretical Physics, Oxford University, Mike went as a post-doc to Minneapolis. He then joined the Statistical Physics Group in the Theoretical Physics Division, Harwell, where he stayed for over 20 years, with a brief interlude in Saclay. In the late 1980s, Mike made a transition to become Professor of Physics at the University of Keele, where he stayed for a decade until University College London was fortunate in being able to tempt him to join the Condensed Matter and Material Physics Group, where there was already a significant materials modelling initiative. Over the years, Mike has made many important contributions, some with impact on other areas of science, others with significance in technology areas such as nuclear safety. Thus, he developed a form of quantum transition-state theory, generalizing Eyring's well-known classical transition-state theory to the case of quantum particles, such as hydrogen, diffusing in condensed matter. He pioneered quantum methods for calculating defect energetics in solids, and then molecular processes on surfaces. He synthesised these approaches into very general ways to calculate thermodynamic free energies of condensed matter from first principles, drawing on his early experience of statistical physics. These methods led to rapid advances in the study

  8. Universality in radiative corrections for non-supersymmetric heterotic vacua

    CERN Document Server

    Angelantonj, C; Tsulaia, Mirian

    2016-01-01

    Properties of moduli-dependent gauge threshold corrections in non-supersymmetric heterotic vacua are reviewed. In the absence of space-time supersymmetry these amplitudes are no longer protected and receive contributions from the whole tower of string states, BPS and not. Never-theless, the difference of gauge thresholds for non-Abelian gauge groups displays a remarkable universality property, even when supersymmetry is absent. We present a simple heterotic construction that shares this universal behaviour and expose the necessary conditions on the super-symmetry breaking mechanism for universality to occur.

    Our understanding of ordinary matter is remarkably accurate and complete, but it is based on principles that are very strange and unfamiliar. As I'll explain, we've come to understand matter to be a Music of the Void, in a remarkably literal sense. Just as we physicists finalized that wonderful understanding, towards the end of the twentieth century, astronomers gave us back our humility, by informing us that ordinary matter - what we, and chemists and biologists, and astronomers themselves, have been studying all these centuries constitutes only about 5% of the mass of the universe as a whole. I'll describe some of our promising attempts to rise to this challenge by improving, rather than merely complicating, our description of the world.

  8. Universality of accelerating change

    Science.gov (United States)

    Eliazar, Iddo; Shlesinger, Michael F.

    2018-03-01

    On large time scales the progress of human technology follows an exponential growth trend that is termed accelerating change. The exponential growth trend is commonly considered to be the amalgamated effect of consecutive technology revolutions - where the progress carried in by each technology revolution follows an S-curve, and where the aging of each technology revolution drives humanity to push for the next technology revolution. Thus, as a collective, mankind is the 'intelligent designer' of accelerating change. In this paper we establish that the exponential growth trend - and only this trend - emerges universally, on large time scales, from systems that combine together two elements: randomness and amalgamation. Hence, the universal generation of accelerating change can be attained by systems with no 'intelligent designer'.

    2007-01-01

    Good afternoon. Before providing the closing remarks on behalf of the NEA, I would like to take this opportunity and make some personal reflections, if you allow me Mr. Chairman. I have had the opportunity to take part in the three workshops on public communication organised by the NEA. In the first one in Paris in 2000, representing my country, Spain, and in the two last ones in Ottawa in 2004 and Tokyo today, on behalf of the NEA. The topics for the three workshops follow a logical order, first the focus was on investing in trust in a time when public communication was becoming a big challenge for the regulators. Second, maintaining and measuring public confidence to assess how credible regulators are in front of the public; and finally here in Tokyo, transparency, which is a basic element to achieve trust and credibility. In my view, a regulatory decision has three main components, it has to be technically sound. legally correct and well communicated. The emphasis in the early years was in the technical matters, till legal issues became a key element to achieve the political acceptance from governments and local authorities. Finally the public communication aspects resulted into a major effort and challenge to achieve social acceptance. (author)

    1986-01-01

    My task in this talk is to review the happenings of this workshop from a theoretical perspective, and to emphasize lines for possible future research. My remarks are organized into a theoretical overview of the what, why, (mainly the hierarchy problem) how, (supersymmetry must be broken: softly or spontaneously, and if the latter, by means of a new U tilde(1) gauge group or through the chiral superfields) when (how heavy are supersymmetric partner particles in different types of theories) and where (can one find evidence for) supersymmetry. In the last part are discussed various ongoing and future searches for photinos γ tilde, gravitinos G tilde, the U vector boson, shiggses H tilde, squarks q tilde and sleptons l tilde, gluinos g tilde, winos W tilde and other gauginos, as well as hunts for indirect effects of supersymmetry, such as for example in baryon decay. Finally there is a little message of encouragement to our experimental colleagues, based on historical precedent. (orig.)

    My topic is Kant’s theory of historical progress. My approach is primarily textual and contextual. I analyse in some detail Kant’s three most important essays on the topic: ‘Idea for a Universal History’, the third part of ‘Theory and Practice’ and the second part of The Conflict of the Faculties. I devote particular attention to the Kant-Herder debate about progress, but also discuss Rousseau, Mendelssohn, Hegel and others.

    Vineyard, M.F.; Gilfoyle, G.P.; Major, R.W.

    1996-01-01

    Summarized in this report is the progress achieved during the period from November 1, 1995 to October 31, 1996. The experimental work described in this report is in preparation for the electromagnetic nuclear physics research program in Hall B at Thomas Jefferson National Accelerator Facility (TJNAF). Much progress has been made this year toward the realization of the physics program in Hall B. The Program Advisory Committee (PAC) reviewed all of the Hall B physics proposals and assigned scientific ratings to those not previously rated. Updates on these proposals were submitted to the PAC for this review and can be found in this report. Also included in this report is a summary of the progress achieved on an experiment that the authors are collaborating on to measure rare radiative decays of the φ meson. This experiment received the PAC's highest rating and will use the Hall B photon tagger and a lead glass calorimeter housed in the alcove upstream of the beam dump. After nearly a decade of planning and construction, the CEBAF Large Acceptance Spectrometer (CLAS) will be commissioned next year. The authors have been members of the CLAS Collaboration since its inception and their contributions to the construction of the CLAS include the development of the drift-chamber gas system, drift-chamber software, and controls software. Major has been leading the effort in the construction of the gas system. In the last year, the gas system components built at the University of Richmond have been installed in the Hall B gas shed and the initial operation of the system has begun. Gilfoyle is coordinating the software development for the CLAS drift chambers. Considerable progress has been made this year in developing software for the analysis of the drift-chamber data. Vineyard served as coordinator of the γ3 Running Period for the CLAS Collaboration and he is also responsible for the development of the drift-chamber gas system controls

  17. The origin of the universe and nuclear synthesis

    Directory of Open Access Journals (Sweden)

    J. P. F. Sellschop

    1988-03-01

    Full Text Available The origin of the universe and nuclear synthesis are discussed in this paper. The concept of the “Big Bang” is introduced in cosmology from observational evidence that the universe is expanding. The language of elementary particle physics is used to describe the evolution of the universe starting at a very small fraction of a second after the "Big Bang”. Various “Eras” are identified during which certain nuclear processes predominate. At a later stage the remarkable nuclear synthesis of carbon takes place, leading to the evolution of other elements. Neutrino measurements are important to validate physical theories in this field and some results of such measurements by the WITS-CSIR Schonland Research Centre are presented.

  18. Progressive universalism? The impact of targeted coverage on health care access and expenditures in Peru.

    Science.gov (United States)

    Neelsen, Sven; O'Donnell, Owen

    2017-12-01

    Like other countries seeking a progressive path to universalism, Peru has attempted to reduce inequalities in access to health care by granting the poor entitlement to tax-financed basic care without charge. We identify the impact of this policy by comparing the target population's change in health care utilization with that of poor adults already covered through employment-based insurance. There are positive effects on receipt of ambulatory care and medication that are largest among the elderly and the poorest. The probability of getting formal health care when sick is increased by almost two fifths, but the likelihood of being unable to afford treatment is reduced by more than a quarter. Consistent with the shallow coverage offered, there is no impact on use of inpatient care. Neither is there any effect on average out-of-pocket health care expenditure, but medical spending is reduced by up to 25% in the top quarter of the distribution.

  20. Remarks on ''Neutrino masses and mixing angles in a predictive theory of fermion masses''

    International Nuclear Information System (INIS)

    Lavoura, L.; Silva, J.P.

    1994-01-01

    In the extension of the Dimopoulos-Hall-Raby model of the fermion mass matrices to the neutrino sector, there is an entry in the up-quark and neutrino Dirac mass matrices which can be assumed to arise from the Yukawa coupling of a 120, instead of a 10 or a 126, of SO(10). Although this assumption leads to an extra undetermined complex parameter in the model, the resulting lepton mixing matrix exhibits the remarkable feature that the ν τ does not mix with the other two neutrinos. Making a reasonable assumption about the extra parameter, we are able to fit the large-mixing-angle MSW solution of the solar-neutrino problem, and we obtain m ντ ∼10 eV, the right mass range to close the Universe. Other possibilities for explaining the solar-neutrino deficit are also discussed

  1. Counting Highly Cited Papers for University Research Assessment: Conceptual and Technical Issues

    Science.gov (United States)

    Rodríguez-Navarro, Alonso

    2012-01-01

    A Kuhnian approach to research assessment requires us to consider that the important scientific breakthroughs that drive scientific progress are infrequent and that the progress of science does not depend on normal research. Consequently, indicators of research performance based on the total number of papers do not accurately measure scientific progress. Similarly, those universities with the best reputations in terms of scientific progress differ widely from other universities in terms of the scale of investments made in research and in the higher concentrations of outstanding scientists present, but less so in terms of the total number of papers or citations. This study argues that indicators for the 1% high-citation tail of the citation distribution reveal the contribution of universities to the progress of science and provide quantifiable justification for the large investments in research made by elite research universities. In this tail, which follows a power low, the number of the less frequent and highly cited important breakthroughs can be predicted from the frequencies of papers in the upper part of the tail. This study quantifies the false impression of excellence produced by multinational papers, and by other types of papers that do not contribute to the progress of science. Many of these papers are concentrated in and dominate lists of highly cited papers, especially in lower-ranked universities. The h-index obscures the differences between higher- and lower-ranked universities because the proportion of h-core papers in the 1% high-citation tail is not proportional to the value of the h-index.

    2004-2011 Final Report for AFCI University Fellowship Program. The goal of this effort was to be supportive of university students and university programs - particularly those students and programs that will help to strengthen the development of nuclear-related fields. The program also supported the stability of the nuclear infrastructure and developed research partnerships that are helping to enlarge the national nuclear science technology base. In this fellowship program, the U.S. Department of Energy sought master's degree students in nuclear, mechanical, or chemical engineering, engineering/applied physics, physics, chemistry, radiochemistry, or fields of science and engineering applicable to the AFCI/Gen IV/GNEP missions in order to meet future U.S. nuclear program needs. The fellowship program identified candidates and selected full time students of high-caliber who were taking nuclear courses as part of their degree programs. The DOE Academic Program Managers encouraged fellows to pursue summer internships at national laboratories and supported the students with appropriate information so that both the fellows and the nation's nuclear energy objectives were successful.

    1984-01-01

    The tenth seminar on environment of the National Institute of Radiological Sciences was held in Chiba on December 9 and 10, 1982, under the joint auspices with Japan Health Physics Society. The recent progress of the measuring techniques for environmental radiation substances is remarkable. The Japanese data on environmental radiation presented to the UN Scientific Committee on the Effect of Atomic Radiation have obtained very high esteem because the data have been reliable due to the progress of measuring techniques. However, this field is in steady progress and changes rapidly, therefore, this seminar was planned. In this report, the history of the analysis and measurement of environmental radioactivity, the method of sampling and pretreatment operation for such environmental specimens as gaseous radionuclides, atmospheric floating dust, soil, agricultural products, sea water and sea bottom sediment, marine life, foods and living bodies, the progress of chemical separation process, the automation of analysis and measurement, the progress of the analysis of low level nuclides with long half-value period, the manual for the analysis and measurement, the quality of the analysis and measurement and its assurance are described.

    1991-01-01

    A long-lasting immunological suppression action seems to be produced by total lymphoid irradiation; some authors emphasize the favorable effect of this treatment on chronic progressive multiple sclerosis. In order to evaluate the actual role of TLI, 6 patients affected with chronic progressive multiple sclerosis were submitted to TLI with shaped and personalized fields at the Istituto del Radio, University of Brescia, Italy. The total dose delivered was 19.8 Gy in 4 weeks, 1.8 Gy/day, 5d/w; a week elapsed between the first and the second irradiation course. Disability according to Kurtzke scale was evaluated, together with blood lymphocyte count and irradiation side-effects, over a mean follow-up period of 20.8 months (range: 13-24). Our findings indicate that: a) disease progression was not markedly reduced by TLI; b) steroid hormones responsivity was restored after irradiation, and c) side-effects were mild and tolerable

    Rutland, Mark W

    2017-07-01

    It is an honour to be charged with providing the concluding remarks for a Faraday Discussion. As many have remarked before, it is nonetheless a prodigious task, and what follows is necessarily a personal, and probably perverse, view of a watershed event in the Chemical Physics of Electroactive materials. The spirit of the conference was captured in a single sentence during the meeting itself."It is the nexus between rheology, electrochemistry, colloid science and energy storage". The current scientific climate is increasingly dominated by a limited number of global challenges, and there is thus a tendency for research to resemble a football match played by 6 year olds, where everyone on the field chases the (funding) ball instead of playing to their "discipline". It is thus reassuring to see how the application of rigorous chemical physics is leading to ingenious new solutions for both energy storage and harvesting, via, for example, nanoactuation, electrowetting, ionic materials and nanoplasmonics. In fact, the same language of chemical physics allows seamless transition between applications as diverse as mechano-electric energy generation, active moisture transport and plasmonic shutters - even the origins of life were addressed in the context of electro-autocatalysis!

    Zhang, Jing; Yuan, Fuqing; Du, Yong

    2013-01-01

    Highlights: • A two-step progressive solution treatment schedule was proposed. • The treatment enhanced dissolution of ternary eutectic phases in Mg–Zn–Al alloy. • Solution temperature could break the limit of the ternary eutectic temperature. • There was no microstructural over-heating defect during the progressive heating. • The τ precipitates have a remarkable dispersion strengthening effect. - Abstract: A two-step progressive solution treatment was designed and performed on an as-extruded Mg–7Zn–3Al–0.7Er alloy. The resultant microstructure and mechanical properties were examined by means of scanning electron microscopy, X-ray diffractometer, differential scanning calorimetry and hardness testing. The results showed that the two-step progressive solution treatment could enhance the dissolution of the ternary eutectic phases in the Mg–Zn–Al system without the formation of microstructure over-heating defects. After homogenization for 50 h at 325 °C, the volume fraction of the undissolved particles in the Mg–7Zn–3Al–0.7Er alloy ingot was ∼4.1%. Two-step progressive solution treatment performed on the as-extruded alloy could further dissolve the particles. Only 1.5% undissolved particles remained after the treatment. The supersaturated degree of both the dissolved solute atoms and vacancies in the α-Mg matrix was expected to be increased, resulting in an enhanced age-strengthening, compared with normal solution and aging treatments. Moreover, the processed alloy exhibited a homogenous and stable fine grain structure. Remarkable dispersion strengthening effect of ternary τ (Mg 32 (Al,Zn) 49 ) precipitates occurred in Mg–Zn–Al alloy was also identified

    Science.gov (United States)

    Chai, Herzl; Lee, James J-W; Constantino, Paul J; Lucas, Peter W; Lawn, Brian R

    2009-05-05

    Tooth enamel is inherently weak, with fracture toughness comparable with glass, yet it is remarkably resilient, surviving millions of functional contacts over a lifetime. We propose a microstructural mechanism of damage resistance, based on observations from ex situ loading of human and sea otter molars (teeth with strikingly similar structural features). Section views of the enamel implicate tufts, hypomineralized crack-like defects at the enamel-dentin junction, as primary fracture sources. We report a stabilization in the evolution of these defects, by "stress shielding" from neighbors, by inhibition of ensuing crack extension from prism interweaving (decussation), and by self-healing. These factors, coupled with the capacity of the tooth configuration to limit the generation of tensile stresses in largely compressive biting, explain how teeth may absorb considerable damage over time without catastrophic failure, an outcome with strong implications concerning the adaptation of animal species to diet.

  19. Cosmological challenges in theories with extra dimensions and remarks on the horizon problem

    International Nuclear Information System (INIS)

    Chung, Daniel J. H.; Freese, Katherine

    2000-01-01

    We consider the cosmology that results if our observable universe is a 3-brane in a higher dimensional universe. In particular, we focus on the case where our 3-brane is located at the Z 2 symmetry fixed plane of a Z 2 symmetric five-dimensional spacetime, as in the Horava-Witten model compactified on a Calabi-Yau manifold. As our first result, we find that there can be substantial modifications to the standard Friedmann-Robertson-Walker (FRW) cosmology; as a consequence, a large class of such models is observationally inconsistent. In particular, any relationship between the Hubble constant and the energy density on our brane is possible, including (but not only) FRW. Generically, due to the existence of the bulk and the boundary conditions on the orbifold fixed plane, the relationship is not FRW, and hence cosmological constraints coming from big bang nucleosynthesis, structure formation, and the age of the universe difficult to satisfy. We do wish to point out, however, that some specific choices for the bulk stress-energy tensor components do reproduce normal FRW cosmology on our brane, and we have constructed an explicit example. As our second result, for a broad class of models, we find a somewhat surprising fact: the stabilization of the radius of the extra dimension and hence the four dimensional Planck mass requires unrealistic fine-tuning of the equation of state on our 3-brane. In the last third of the paper, we make remarks about causality and the horizon problem that apply to any theory in which the volume of the extra dimension determines the four-dimensional gravitational coupling. We point out that some of the assumptions that lead to the usual inflationary requirements are modified. (c) 1999 The American Physical Society

  20. Remarkable recoveries: research and practice from a patient's perspective.

    Science.gov (United States)

    Barasch, Marc Ian

    2008-08-01

    Mind-body therapies are often portrayed in the literature as self-palliative, adjunctive, and complementary, but rarely as contributive to cure. Many physicians continue to view them as acceptable indulgences so long as they are harmless and the patient remains fully compliant with a standard treatment regimen. The possibility that such modalities might help drive the healing process itself is infrequently acknowledged. This article addresses the topic of such therapies, examining remarkable recoveries in cancer, and suggesting the need for a "Remarkable Recovery Registry" to expand the literature on these cases. The author discusses the importance of complementary alternative medicine, and emotional and pyschologic support in the treatment regimen, and the need for health care providers and patients to work together to provide the best emotional environment for the healing process.

    Based on an earlier introduced new class of generalized gravity-matter models defined in terms of two independent non-Riemannian volume forms (alternative generally covariant integration measure densities) on the space-time manifold, we derive an effective ``Einstein-frame'' theory featuring the following remarkable properties: (i) We obtain effective potential for the cosmological scalar field possessing two infinitely large flat regions which allows for a unified description of both early Universe inflation as well as of present dark energy epoch; (ii) for a specific parameter range the model possesses a non-singular stable ``emergent Universe'' solution which describes an initial phase of evolution that precedes the inflationary phase.

    CERN Document Server

    Steinhardt, Paul J

    2007-01-01

    The Big Bang theory—widely regarded as the leading explanation for the origin of the universe—posits that space and time sprang into being about 14 billion years ago in a hot, expanding fireball of nearly infinite density. Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place. In Endless Universe, Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” (Discover). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to t...

  8. Towards Universal Health Coverage via Social Health Insurance in China: Systemic Fragmentation, Reform Imperatives, and Policy Alternatives.

    China's remarkable progress in building a comprehensive social health insurance (SHI) system was swift and impressive. Yet the country's decentralized and incremental approach towards universal coverage has created a fragmented SHI system under which a series of structural deficiencies have emerged with negative impacts. First, contingent on local conditions and financing capacity, benefit packages vary considerably across schemes, leading to systematic inequity. Second, the existence of multiple schemes, complicated by massive migration, has resulted in weak portability of SHI, creating further barriers to access. Third, many individuals are enrolled on multiple schemes, which causes inefficient use of government subsidies. Moral hazard and adverse selection are not effectively managed. The Chinese government announced its blueprint for integrating the urban and rural resident schemes in early 2016, paving the way for the ultimate consolidation of all SHI schemes and equal benefits for all. This article proposes three policy alternatives to inform the consolidation: (1) a single-pool system at the prefectural level with significant government subsidies, (2) a dual-pool system at the prefectural level with risk-equalization mechanisms, and (3) a household approach without merging existing pools. Vertical integration to the provincial level is unlikely to happen in the near future. Two caveats are raised to inform this transition towards universal health coverage.

    Natural enzymes as biological catalysts possess remarkable advantages, especially their highly efficient and selective catalysis under mild conditions. However, most natural enzymes are proteins, thus exhibiting an inherent low durability to harsh reaction conditions. Artificial enzyme mimetics have been pursued extensively to avoid this drawback. Quite recently, some inorganic nanoparticles (NPs) have been found to exhibit unique enzyme mimetics. In addition, their much higher stability overcomes the inherent disadvantage of natural enzymes. Furthermore, easy mass-production and low cost endow them more benefits. As a new member of artificial enzyme mimetics, they have received intense attention. In this review article, major progress in this field is summarized and future perspectives are highlighted.

  14. Universal bursty behavior in the air transportation system.

    Ito, Hidetaka; Nishinari, Katsuhiro

    2015-12-01

    Social activities display bursty behavior characterized by heavy-tailed interevent time distributions. We examine the bursty behavior of airplanes' arrivals in hub airports. The analysis indicates that the air transportation system universally follows a power-law interarrival time distribution with an exponent α=2.5 and an exponential cutoff. Moreover, we investigate the mechanism of this bursty behavior by introducing a simple model to describe it. In addition, we compare the extent of the hub-and-spoke structure and the burstiness of various airline networks in the system. Remarkably, the results suggest that the hub-and-spoke network of the system and the carriers' strategy to facilitate transit are the origins of this universality.

    Yadav, Anil Kumar; Bhardwaj, Vinod Kumar

    2018-06-01

    In this paper we have searched for the existence of Lyra’s cosmology in a hybrid universe with minimal interaction between dark energy and normal matter using Bianchi-V space-time. To derive the exact solution, the average scale factor is taken as a={({t}n{e}kt)}\\frac{1{m}} which describes the hybrid nature of the scale factor and generates a model of the transitioning universe from the early deceleration phase to the present acceleration phase. The quintessence model makes the matter content of the derived universe remarkably able to satisfy the null, dominant and strong energy condition. It has been found that the time varying displacement β(t) co-relates with the nature of cosmological constant Λ(t). We also discuss some physical and geometrical features of the universe.

    Jesús Salinas Ibáñez

    2018-03-01

    Full Text Available Recently, the term of digital university has been a buzzword or trend in different contexts in Spanish-speaking countries. However, there is no available clear definition of the concept that helps us specify its implementation further. Therefore, this study was aimed at analyzing the different existing conceptions of digital university in Ibero-America, via a systematic literature review and the analysis of the semantic field through a network analysis. This enabled us to identify what was understood by being a digital university from the perspective of different Ibero-American universities. Spanish keywords derived from the thesaurus -including “digital university”- were used in the search through diverse catalogs and databases, and documents of different kinds were found between 2007 and 2017. The literature review was based on the abstracts of the documents and we considered the creation of categories with diverse topics that represent how Ibero-America understands the digital university and with which restrictions has to deal with. The discussion incorporates the integration of those categories and topics into the digital university models that were previously identified. As a conclusion, a summary on the concept of digital university is presented and we point towards some remarks so that the conception is made a reality in its practice.

  6. Maryland University sectored isochronous cyclotron (MUSIC): Progress report No. 14

    Energy Technology Data Exchange (ETDEWEB)

    1967-01-10

    The past quarter has seen further progress in the solution of the problem of achieving a cyclotron which meets or exceeds the performance requirements. The magnet system, with the exception of the trim coils and their supplies, is all on order or about to be ordered, and a high confidence level exists that the system will meet all requirements. The rf system studies, nearly complete, have indicated that the solution chosen will meet the frequency requirements and will be within the power expected. The center studies, complete in the first phase, have resulted in a preliminary center design of the electrostatic focusing system and a design of the magnetic center which provides the required axial focusing. A high degree of cooperation on the center study programs between the U of M and CSF has efficiently yielded these results. The overall schedule continues to be maintained, and the program is expected to be completed on the 37-month schedule. For better control and greater visibility on schedule progress, two reference points have been selected as more immediate objectives. These are 17 July 1967 for the start of the magnet testing program and 2 October 1967 as the start of the rf high power tests. Each task involved is being analyzed with these dates in mind, and they appear to be reasonable.

  7. Proclus' Elaboration of Platonic Remarks on the Problem of Evils, and their Relation to Divine Providence and Efficiency

    Directory of Open Access Journals (Sweden)

    Reza korrang beheshti

    2014-06-01

    Full Text Available Although there is not a fully developed theory of evil in Plato, some various remarks are interspersed throughout his dialogues which provided the main materials for subsequent Platonists to elaborate a systematic doctrine of evil. Proclus is the most distinguished philosopher of the later Neoplatonism whose view became authoritative within the School and thus is most representative of the Neoplatonic doctrine of evil. By a critical assessment of the antecedent theories of evil, Proclus attempts to give a monistic interpretation of Platonic remarks on the problem of evil. According to his explanation, the higher degrees and principles of Being are only and purely good and are not the causes of evils but the good things for all things alone. Evils, however, exist necessarily but only among particular beings in a relative, parasitic, accidental way and dependent upon the good. The parasitic accidental existence of evil does not have a real efficient cause. It arises due to an asymmetry between the activities of the several faculties or powers of a complex particular being. Moreover, the existence of evil is so mixed with and dependent upon the good that despite its opposition to the good, contributes, in its own manner, to the fulfillment of goodness of the whole Universe, being thus reconcilable with Divine Providence and Efficiency.

  13. Universality of low-energy scattering in 2+1 dimensions

    International Nuclear Information System (INIS)

    Chadan, K.; Khuri, N.N.; Martin, A.; Wu, T.T.

    1998-01-01

    For any relativistic quantum field theory in 2+1 dimensions, with no zero mass particles, and satisfying the standard axioms, we establish a remarkable low-energy theorem. The S-wave phase shift, δ 0 (k), k being the c.m. momentum, vanishes as either δ 0 →c/ln(k/m)or δ 0 →O(k 2 ) as k→0. The constant c is universal and c=π/2. This result follows only from the rigorously established analyticity and unitarity properties for 2-particle scattering. This kind of universality was first noted in non-relativistic potential scattering, albeit with an incomplete proof which missed, among other things, an exceptional class of potentials where δ 0 (k) is O(k 2 ) near k=0. We treat the potential scattering case with full generality and rigor, and explicitly define the exceptional class. Finally, we look at perturbation theory in φ 3 4 and study its relation to our non-perturbative result. The remarkable fact here is that in n-th order the perturbative amplitude diverges like (lnthinspk) n as k→0, while the full amplitude vanishes as (lnk) -1 . We show how these two facts can be reconciled. copyright 1998 The American Physical Society

  15. An assessment of progress towards universal health coverage in Brazil, Russia, India, China, and South Africa (BRICS).

    Brazil, Russia, India, China, and South Africa (BRICS) represent almost half the world's population, and all five national governments recently committed to work nationally, regionally, and globally to ensure that universal health coverage (UHC) is achieved. This analysis reviews national efforts to achieve UHC. With a broad range of health indicators, life expectancy (ranging from 53 years to 73 years), and mortality rate in children younger than 5 years (ranging from 10·3 to 44·6 deaths per 1000 livebirths), a review of progress in each of the BRICS countries shows that each has some way to go before achieving UHC. The BRICS countries show substantial, and often similar, challenges in moving towards UHC. On the basis of a review of each country, the most pressing problems are: raising insufficient public spending; stewarding mixed private and public health systems; ensuring equity; meeting the demands for more human resources; managing changing demographics and disease burdens; and addressing the social determinants of health. Increases in public funding can be used to show how BRICS health ministries could accelerate progress to achieve UHC. Although all the BRICS countries have devoted increased resources to health, the biggest increase has been in China, which was probably facilitated by China's rapid economic growth. However, the BRICS country with the second highest economic growth, India, has had the least improvement in public funding for health. Future research to understand such different levels of prioritisation of the health sector in these countries could be useful. Similarly, the role of strategic purchasing in working with powerful private sectors, the effect of federal structures, and the implications of investment in primary health care as a foundation for UHC could be explored. These issues could serve as the basis on which BRICS countries focus their efforts to share ideas and strategies. Copyright © 2014 Elsevier Ltd. All rights reserved.

    International Nuclear Information System (INIS)

    Kaku, Michio; Lykken, J.

    1986-01-01

    We propose a Kaluza-Klein cosmology by reversing the usual scenario: instead of starting with a flat 4+N dimensional universe in which N of the dimensions curl up into a compact manifold, we start with a compact 3+N dimensional manifold in which 3 of the dimensions are allowed to peel off and expand into the known universe. We reverse the usual ''spontaneous compactification'' scenario begin with a closed manifold Msup(3+N) which undergoes ''spontaneous fissioning'' into a product manifold M 3 xMsup(N). Remarkably, the 3-dimensional universe M 3 can undergo a rapid de Sitter expansion large enough to solve the horizon and flatness problem. We call this ''topological inflation'', which we propose as an alternative to the usual GUT inflation. The inflationary phase automatically terminates into a big bang phase. (orig.)

    2011-12-01

    In recent years, significant progresses have been got in study on pathogenesis, treatment and prognosis of myelodysplastic syndromes (MDS), especially on use of new technology, that has great importance for cytogenetics of MDS. Recently, the progress of cytogenetic detection in MDS is very remarkable. Based on the metaphase cytogenetics (MC) method, prognostic significance of cytogenetics in MDS was clarified gradually. For example, people have known the prognostic significance of 12 p-, 11 q-, +21, t(11(q23)), although these genetic abnormalities are rare in the MDS. In addition, chromosome mutation emerged in the process of MDS may indicate the poor prognosis. On the other hand, with the use of SNP-A and aCGH in the study of genetics, MDS cytogenetic abnormality detection rate has been further improved and can reach to 78%. At the same time, some of MDS patients with the "normal karyotype" detected by MC have new hidden aberrations through the SNP or CGH detection, and these patients have a poorer prognosis. In this review, the advances of study on cytogenetic detection for MDS based on MC and SNP-A or aCGH methods are summarized.

    Bursty transport phenomena associated with convective motion present universal statistical characteristics among different physical systems. In this Letter, a stochastic univariate model and the associated probability distribution function for the description of bursty transport in plasma turbulence is presented. The proposed stochastic process recovers the universal distribution of density fluctuations observed in plasma edge of several magnetic confinement devices and the remarkable scaling between their skewness S and kurtosis K. Similar statistical characteristics of variabilities have been also observed in other physical systems that are characterized by convection such as the x-ray fluctuations emitted by the Cygnus X-1 accretion disc plasmas and the sea surface temperature fluctuations.

Initial rf study and design work indicates no major technical problems, although there are many difficult engineering problems to be solved. Center studies are just being started. Building installation and interface problems are being dealt with effectively, and no significant problems are anticipated in this area.

    Most of the mass in the universe is in the form of dark matter—a new type of nonbaryonic particle not yet detected in the laboratory or in other detection experiments. The evidence for the existence of dark matter through its gravitational impact is clear in astronomical observations—from the early observations of the large motions of galaxies in clusters and the motions of stars and gas in galaxies, to observations of the large-scale structure in the universe, gravitational lensing, and the cosmic microwave background. The extensive data consistently show the dominance of dark matter and quantify its amount and distribution, assuming general relativity is valid. The data inform us that the dark matter is nonbaryonic, is “cold” (i.e., moves nonrelativistically in the early universe), and interacts only weakly with matter other than by gravity. The current Lambda cold dark matter cosmology—a simple (but strange) flat cold dark matter model dominated by a cosmological constant Lambda, with only six basic parameters (including the density of matter and of baryons, the initial mass fluctuations amplitude and its scale dependence, and the age of the universe and of the first stars)—fits remarkably well all the accumulated data. However, what is the dark matter? This is one of the most fundamental open questions in cosmology and particle physics. Its existence requires an extension of our current understanding of particle physics or otherwise point to a modification of gravity on cosmological scales. The exploration and ultimate detection of dark matter are led by experiments for direct and indirect detection of this yet mysterious particle. PMID:26417091

    A brief review of recent progress in researches, productions and applications of full distributed fiber Raman photon sensors at China Jiliang University (CJLU) is presented. In order to improve the measurement distance, the accuracy, the space resolution, the ability of multi-parameter measurements, and the intelligence of full distributed fiber sensor systems, a new generation fiber sensor technology based on the optical fiber nonlinear scattering fusion principle is proposed. A series of new generation full distributed fiber sensors are investigated and designed, which consist of new generation ultra-long distance full distributed fiber Raman and Rayleigh scattering photon sensors integrated with a fiber Raman amplifier, auto-correction full distributed fiber Raman photon temperature sensors based on Raman correlation dual sources, full distributed fiber Raman photon temperature sensors based on a pulse coding source, full distributed fiber Raman photon temperature sensors using a fiber Raman wavelength shifter, a new type of Brillouin optical time domain analyzers (BOTDAs) integrated with a fiber Raman amplifier for replacing a fiber Brillouin amplifier, full distributed fiber Raman and Brillouin photon sensors integrated with a fiber Raman amplifier, and full distributed fiber Brillouin photon sensors integrated with a fiber Brillouin frequency shifter. The Internet of things is believed as one of candidates of the next technological revolution, which has driven hundreds of millions of class markets. Sensor networks are important components of the Internet of things. The full distributed optical fiber sensor network (Rayleigh, Raman, and Brillouin scattering) is a 3S (smart materials, smart structure, and smart skill) system, which is easy to construct smart fiber sensor networks. The distributed optical fiber sensor can be embedded in the power grids, railways, bridges, tunnels, roads, constructions, water supply systems, dams, oil and gas pipelines and other

    Since 2015, 84 countries and territories reported evidence of vector-borne Zika Virus (ZIKV) transmission. The World Health Organization (WHO) declared that ZIKV and associated consequences especially the neurological autoimmune disorder Guillain–Barré syndrome (GBS) and microcephaly will remain a significant enduring public health challenge requiring intense action. We apply a standardization of the multi-subcutaneous dorsal inoculation method to systematically summarize clinical neurological manifestation, viral distribution, and tissue damage during the progress of viremia and systemic spread in suckling mouse models. We found that C57BL/6 and Kunming mice (KM) both showed remarkable and uniform neurologic manifestations. C57BL/6 owned the highest susceptibility and pathogenicity to the nervous system, referred to as movement disorders, with 100% incidence, while KM was an economic model for a Chinese study characterized by lower limb weakness with 62% morbidity. Slight yellow extraocular exudates were observed in BALB/c, suggesting the association with similar ocular findings to those of clinical cases. The virus distribution and pathological changes in the sera, brains, livers, kidneys, spleens, and testes during disease progression had strong regularity and uniformity, demonstrating the effectiveness and plasticity of the animal models. The successful establishment of these animal models will be conducive to expound the pathogenic mechanism of GBS. PMID:28661429

    Websites as one of the initial steps towards an e-government adoption do facilitate delivery of online and customer-oriented services. In this study we intended to investigate the role of the websites of medical universities in providing educational and research services following the E-government maturity model in the Iranian universities. This descriptive and cross- sectional study was conducted through content analysis and benchmarking the websites in 2012. The research population included the entire medical university website (37). Delivery of educational and research services through these university websites including information, interaction, transaction, and Integration were investigated using a checklist. The data were then analyzed by means of descriptive statistics and using SPSS software. Level of educational and research services by websites of the medical universities type I and II was evaluated medium as 1.99 and 1.89, respectively. All the universities gained a mean score of 1 out of 3 in terms of integration of educational and research services. Results of the study indicated that Iranian universities have passed information and interaction stages, but they have not made much progress in transaction and integration stages. Failure to adapt to e-government in Iranian medical universities in which limiting factors such as users' e-literacy, access to the internet and ICT infrastructure are not so crucial as in other organizations, suggest that e-government realization goes beyond technical challenges.

    Although still in its infant stage, synthetic biology has achieved remarkable development and progress during the past decade. Synthetic biology applies engineering principles to design and construct gene circuits uploaded into living cells or organisms to perform novel or improved functions, and it has been widely used in many fields. In this review, we describe the recent advances of mammalian synthetic biology for the treatment of diseases. We introduce common tools and design principles of synthetic gene circuits, and then we demonstrate open-loop gene circuits induced by different trigger molecules used in disease diagnosis and close-loop gene circuits used for biomedical applications. Finally, we discuss the perspectives and potential challenges of synthetic biology for clinical applications.

  6. Entropy in an expanding universe

    International Nuclear Information System (INIS)

    Frautschi, S.C.

    1986-01-01

    The present picture of the evolution of the universe, based on the Big Bang, suggests a remarkably different and more interesting situation. In the beginning there is a hot gas, nearly homogeneous and in thermal equilibrium [the 3 0 blackbody radiation, reaching us isotropically from all directions, is a relic of, and evidence for, this early state]. The picture of cosmic evolution, seemingly paradoxical in the light of the law of thermodynamics, motivates the questions the author considers in this paper: How can disequilibrium, order, and in particular the free energy supplies which enable life to maintain its organization, emerge from an apparently chaotic early universe in thermal and chemical equilibrium; will free energy supplies continue to become available and be utilized in the future, or will some sort of heat death eventually settle in? The evolution of free energy and entropy in the universe could not be treated accurately on the basis of physics known in the 19th century. However, various 20th century discoveries and ideas make informed discussion of such issues possible, even though definitive answers are not yet in hand. The author discusses some of the ideas which are quite recent, and are currently undergoing rapid development

  7. Dark energy: a quantum fossil from the inflationary universe?

    International Nuclear Information System (INIS)

    Sola, Joan

    2008-01-01

    The discovery of dark energy (DE) as the physical cause for the accelerated expansion of the Universe is the most remarkable experimental finding of modern cosmology. However, it leads to insurmountable theoretical difficulties from the point of view of fundamental physics. Inflation, on the other hand, constitutes another crucial ingredient, which seems necessary to solve other cosmological conundrums and provides the primeval quantum seeds for structure formation. One may wonder if there is any deep relationship between these two paradigms. In this work, we suggest that the existence of the DE in the present Universe could be linked to the quantum field theoretical mechanism that may have triggered primordial inflation in the early Universe. This mechanism, based on quantum conformal symmetry, induces a logarithmic, asymptotically free, running of the gravitational coupling. If this evolution persists in the present Universe, and if matter is conserved, the general covariance of Einstein's equations demands the existence of dynamical DE in the form of a running cosmological term, Λ, whose variation follows a power law of the redshift

    This report summarizes the progress and accomplishments of research supported by DOE. This work involves the experimental investigation of fundamental atomic processes in collisions of few-electron, charged projectile ions with neutral gas targets or electrons. The major emphasis is the study of collision processes involving two active electrons, and particularly those in which the electron-electron interaction plays a role. New results have been obtained for studies involving (1) continuum-electron emission, (2) double ionization of helium and Li + , and (3) resonant recombination of atomic ions. Experiments were conducted using accelerators at Western Michigan University, Michigan State University, Indiana University, Lawrence Livermore Laboratory, and the Institute of Nuclear Research, Debrecen, Hungary. Brief summaries of work completed and work in progress are given

  9. Universal Fault-Tolerant Gates on Concatenated Stabilizer Codes

    Directory of Open Access Journals (Sweden)

    Theodore J. Yoder

    2016-09-01

    Full Text Available It is an oft-cited fact that no quantum code can support a set of fault-tolerant logical gates that is both universal and transversal. This no-go theorem is generally responsible for the interest in alternative universality constructions including magic state distillation. Widely overlooked, however, is the possibility of nontransversal, yet still fault-tolerant, gates that work directly on small quantum codes. Here, we demonstrate precisely the existence of such gates. In particular, we show how the limits of nontransversality can be overcome by performing rounds of intermediate error correction to create logical gates on stabilizer codes that use no ancillas other than those required for syndrome measurement. Moreover, the logical gates we construct, the most prominent examples being Toffoli and controlled-controlled-Z, often complete universal gate sets on their codes. We detail such universal constructions for the smallest quantum codes, the 5-qubit and 7-qubit codes, and then proceed to generalize the approach. One remarkable result of this generalization is that any nondegenerate stabilizer code with a complete set of fault-tolerant single-qubit Clifford gates has a universal set of fault-tolerant gates. Another is the interaction of logical qubits across different stabilizer codes, which, for instance, implies a broadly applicable method of code switching.

  11. The baryon asymmetry of the Universe

    International Nuclear Information System (INIS)

    Barrow, J.D.

    1980-01-01

    An interaction between cosmology and particle physics has been mediated by the development of a unified approach to the fundamental symmetries of nature. The development of a unified theory of the strong and electro-weak interactions has encountered a potential hurdle to its progress. The underlying symmetry between the strong and electro-weak interactions may only be restored at energies exceeding approximately 10 14 GeV and such conditions can only be probed by an indirect retrospection into the first instants of the hot big bang origin of the Universe. The author aims to describe some of the recent developments surrounding grand unified theories (GUT's) of the strong and electro-weak interactions together with their relation to the question of the matter-antimatter asymmetry of the Universe and the relative cosmic abundances of photons and nucleons. Further progress is hindered by the fact that super-unified theory must also encompass the gravitational interaction. (Auth.)

    Kirshner HS

    2014-06-01

    Full Text Available Howard S KirshnerDepartment of Neurology, Vanderbilt University Medical Center, Nashville, TN, USAAbstract: Frontotemporal dementias are neurodegenerative diseases in which symptoms of frontal and/or temporal lobe disease are the first signs of the illness, and as the diseases progress, they resemble a focal left hemisphere process such as stroke or traumatic brain injury, even more than a neurodegenerative disease. Over time, some patients develop a more generalized dementia. Four clinical subtypes characterize the predominant presentations of this illness: behavioral or frontal variant FTD, progressive nonfluent aphasia, semantic dementia, and logopenic primary progressive aphasia. These clinical variants correlate with regional patterns of atrophy on brain imaging studies such as MRI and PET scanning, as well as with biochemical and molecular genetic variants of the disorder. The treatment is as yet only symptomatic, but advances in molecular genetics promise new therapies.Keywords: FTD, behavior variant or frontal variant FTD, pick's disease, PPA, progressive nonfluent aphasia

    Collier, J.G.

    1990-01-01

    The papers, all indexed separately, have been taking stock of the overall position as regards the development of fast reactors in Europe, the USSR, the USA and Japan. Good technical progress has been made with the development of this major source of electrical power for the next century. In Europe, there are two large prototypes operating, Phenix and PFR. There is also a 1200 MW e demonstration reactor (Superphenix), which is now continuing with its commissioning programme after the interruption caused by the leak from the fuel storage vessel. The Soviet Union is pressing ahead with its programme; in the USA FFTF has given outstanding reliability and in Japan the construction of Monju is going well and is on schedule for criticality in 1992. There has been general agreement on the basic economic and performance parameters of the fast reactor and its fuel cycle. In particular, after the first of a kind costs have been met, fast reactor and PWR generating costs are likely to be broadly similar, in the absence of large increases in uranium prices. However, the future of fast reactors is uncertain and the reasons for this are discussed. (author)

    CERN Document Server

    2015-01-01

    "Why"? Why is the world, the Universe the way it is? Is space infinitely large? How small is small? What happens when one continues to divide matter into ever smaller pieces? Indeed, what is matter? Is there anything else besides what can be seen? Pursuing the questions employing the leading notions of physics, one soon finds that the tangible and visible world dissolves — rather unexpectedly — into invisible things and domains that are beyond direct perception. A remarkable feature of our Universe is that most of its constituents turn out to be invisible, and this fact is brought out with great force by this book. Exploring the Invisible Universe covers the gamut of topics in advanced modern physics and provides extensive and well substantiated answers to these questions and many more. Discussed in a non-technical, yet also non-trivial manner, are topics dominated by invisible things — such as Black Holes and Superstrings as well as Fields, Gravitation, the Standard Model, Cosmology, Relativity, the O...

    Professor Li Ao was one of the founders of Chinese burn medicine and one of the most renowned doctors and researchers of burns in China. He established one of the Chinese earliest special departments for burns at Third Military Medical University (TMMU) in 1958. To memorialize Professor Li Ao on his 100th birthday in 2017 and introduce our extensive experience, it is our honor to briefly review the development and achievement of the Chinese burn medicine from TMMU. The epidemiology and outcomes of admitted burn patients since 1958 were reviewed. Furthermore, main achievements of basic and clinical research for the past roughly 60 years were presented. These achievements mainly included the Chinese Rule of Nine, fluid resuscitation protocol, experience in inhalation injury, wound treatment strategies, prevention and treatment of burn infections, nutrition therapy, organ support therapies, and rehabilitation. The progress shaped and enriched modern Chinese burn medicine and promoted the development of world burn medicine.

  4. Chandra Sees Remarkable Eclipse of Black Hole

    Science.gov (United States)

    2007-04-01

    A remarkable eclipse of a supermassive black hole and the hot gas disk around it has been observed with NASA's Chandra X-ray Observatory. This eclipse has allowed two key predictions about the effects of supermassive black holes to be tested. Just as eclipses of the Sun and moon give astronomers rare opportunities to learn about those objects, an alignment in a nearby galaxy has provided a rare opportunity to investigate a supermassive black hole. Illustrations of Black Hole Eclipse Illustrations of Black Hole Eclipse The supermassive black hole is located in NGC 1365, a galaxy 60 million light years from Earth. It contains a so called active galactic nucleus, or AGN. Scientists believe that the black hole at the center of the AGN is fed by a steady stream of material, presumably in the form of a disk. Material just about to fall into a black hole should be heated to millions of degrees before passing over the event horizon, or point of no return. The disk of gas around the central black hole in NGC 1365 produces copious X-rays but is much too small to resolve directly with a telescope. However, the disk was eclipsed by an intervening cloud, so observation of the time taken for the disk to go in and out of eclipse allowed scientists to estimate the size of the disk. Black Hole Animation Black Hole Animation "For years we've been struggling to confirm the size of this X-ray structure," said Guido Risaliti of the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass, and the Italian Institute of Astronomy (INAF). "This serendipitous eclipse enabled us to make this breakthrough." The Chandra team directly measured the size of the X-ray source as about seven times the distance between the Sun and the Earth. That means the source of X-rays is about 2 billion times smaller than the host galaxy and only about 10 times larger than the estimated size of the black hole's event horizon, consistent with theoretical predictions.

  7. Inflationary Cosmology: Is Our Universe Part of a Multiverse

    International Nuclear Information System (INIS)

    Guth, Alan

    2008-01-01

    In 1981, Guth proposed the theory of the inflationary universe, a modification of the Big Bang theory, which is generally accepted by scientists to explain how the universe began. Nevertheless, the Big Bang theory leaves some questions, and the theory of inflation attempts to answer them. Guth states that a repulsive gravitational force generated by an exotic form of matter brought about the expansion of the universe. He postulates that the universe underwent an expansion of astronomical proportions within the first trillionth of a second of its existence, during which the seeds for its large-scale structure were generated. Guth and colleagues have further explored the possibility of mimicking inflation in a hypothetical laboratory, thereby creating a new universe, and they concluded that it might be theoretically possible. If it happened, the new universe would not endanger our own universe. Instead, it would slip through a wormhole, a hypothetical space-time travel shortcut, and rapidly disconnect from our universe. In this talk, Guth will explain the inflationary theory and review the features that make it scientifically plausible. In addition, he will discuss the biggest mystery in cosmology: Why is the value of the cosmological constant, sometimes called the 'anti-gravity' effect, so remarkably small compared to theoretical expectations? Guth will explain how the inflationary theory, combined with other ideas from elementary particle physics and cosmology, can provide a possible explanation for this discrepancy.

    Galaxy redshift surveys have achieved significant progress over the last couple of decades. Those surveys tell us in the most straightforward way what our local Universe looks like. While the galaxy distribution traces the bright side of the Universe, detailed quantitative analyses of the data have even revealed the dark side of the Universe dominated by non-baryonic dark matter as well as more mysterious dark energy (or Einstein's cosmological constant). We describe several methodologies of using galaxy redshift surveys as cosmological probes, and then summarize the recent results from the existing surveys. Finally we present our views on the future of redshift surveys in the era of precision cosmology.

    Denmark has played a substantial role in the history of Northern Europe. Through a nationwide scientific outreach initiative, we collected genetic and anthropometrical data from ∼800 high school students and used them to elucidate the genetic makeup of the Danish population, as well as to assess polygenic predictions of phenotypic traits in adolescents. We observed remarkable homogeneity across different geographic regions, although we could still detect weak signals of genetic structure reflecting the history of the country. Denmark presented genomic affinity with primarily neighboring countries with overall resemblance of decreasing weight from Britain, Sweden, Norway, Germany, and France. A Polish admixture signal was detected in Zealand and Funen, and our date estimates coincided with historical evidence of Wend settlements in the south of Denmark. We also observed considerably diverse demographic histories among Scandinavian countries, with Denmark having the smallest current effective population size compared to Norway and Sweden. Finally, we found that polygenic prediction of self-reported adolescent height in the population was remarkably accurate (R 2 = 0.639 ± 0.015). The high homogeneity of the Danish population could render population structure a lesser concern for the upcoming large-scale gene-mapping studies in the country.

    In this project we proposed to study the real-time dynamics of driven superconducting vortices moving in a periodic potential, using the technique of high-bandwidth scanning Hall probe microscopy to understand the local spatial and temporal characteristics of vortex motion in periodic potentials. During the term of the project we made significant progress towards these goals, but the overall project goal was unfortunately not met. Nonetheless, certain intermediate goals were met, and we believe that even though the project has officially ended we will be able to finish the proposed experiments.

    Eleonora Cappuccilli

    2015-06-01

    Full Text Available During the era of the English Revolutions and shortly after that, some spaces, albeit limited, of female visibility open up. Thanks to the window of opportunity caused by the collapse of censorship, the participation in the radical sects and in the Civil war, some remarkable women succeed in introducing themselves in the public sphere, shaping it since its very genesis. Moreover, analysing law institutions as jointure and feoffment, the attempt is to reconstruct some fragments of juridical female autonomy, which belie the total pervasiveness of coverture in the XVII century. As in private law, in public law women, in the role of queens, gain centrality: the principle of female authority, while safeguards the holding of the monarchical regime, destabilizes its patriarchal structure. Going through the works of Katherine Chidley, Margaret Cavendish, Damaris Masham and Mary Astell, the essay aims at reconstructing women's public voice, a voice which upsets the consolidated frames and subverts the established positions, questioning the same social hierarchies.

    The Nuclear Energy University Program (NEUP) Office assists the U.S. Department of Energy Office of Nuclear Energy (DOE-NE) by administering its University Program. To promote accountable relationships between universities and the Technical Integration Offices (TIOs)/Technology Development Offices (TDOs), a process was designed and administered which includes two competitive Requests for Proposals (RFPs) and two Funding Opportunity Announcements (FOAs) in the following areas: (1) Research and Development (R and D) Grants, (2) Infrastructure improvement, and (3) Scholarships and Fellowships. NEUP will also host periodic reviews of university mission-specific R and D that document progress, reinforce accountability, and assess return on investment; sponsor workshops that inform universities of the Department's research needs to facilitate continued alignment of university R and D with NE missions; and conduct communications activities that foster stakeholder trust, serve as a catalyst for accomplishing NEUP objectives, and provide national visibility of NEUP activities and accomplishments. Year to date efforts to achieve these goals will be discussed.

    Full text: A large number of recent observational data strongly suggest that we live in a flat, accelerating Universe composed by nearly 1/3 of matter (baryonic + dark) and 2/3 of an exotic component with large negative pressure, usually named Dark Energy. The basic set of experiments includes: observations from SNe Ia, CMB anisotropies, baryon acoustic oscillations (BAO) and X-ray data from galaxy clusters. Within the general relativity, the simplest explanation for dark energy is the cosmological constant associated with the zero-point energy density of all quantum fields present in the Universe. However, all estimates for its value are many orders-of-magnitude too large. Many alternative ideas include more exotic candidates for dark energy among them an extremely light scalar field. However, some possible explanations for the present accelerating stage also invokes gravitational physics beyond general relativity. In this way, several observations using satellites and ground-based telescopes are in operation or being planned to test whether dark energy is the cosmological constant or something more exotic, as well as to decide whether or not the standard general relativity can explain cosmic acceleration. In the current view, dark energy is an interesting example of new physics, and, certainly, its possible existence is one of the most profound mysteries of modern physics. In this talk we present a simplified picture of the main results and discuss briefly the difficulties underlying the dark energy paradigm and some of its possible alternatives. (author)

    The programme, The Universe in Your City - Nineteen Capitals, took us to each of Uruguay's nineteen provincial capitals. In each capital we erected our Kappa Crucis Digital Mobile Planetarium and were able to reach a wide range of children of school age, and especially children in "critical contexts" (i.e. socially and economically deprived children). We transported our equipment, together with the exhibition materials for the IYA2009 Cornerstone project, From Earth To The Universe - and set it up in open public spaces, staying in each location for one week and offering an average of nine daily 40-minute presentations. Each session featured information on Galileo Galilei's discoveries, the Uruguayan night sky and the cultural heritage provided by the sky. A record number of 46 428 people participated in the 884 sessions held between April and September; while many more simply visited the exhibition. This reflects the remarkable success of the project.

    The present studies examined the mediating role of self-regulatory mechanisms in the relationship between goal motivation and goal progress in the Self-Concordance Model. First, a systematic review, using meta-analytical path analysis, supported the mediating role of effort and action planning in the positive association between autonomous goal motivation and goal progress. Second, results from two additional empirical studies, using structural equation modeling, lent credence to the mediating role of coping in the relationship between goal motivation and goal progress of university students. Autonomous goal motivation was positively associated with task-oriented coping, which predicted greater goal progress during midterm exams (Study 1, N=702) and at the end of the semester in a different sample (Study 2, N=167). Controlled goal motivation was associated with greater disengagement-oriented coping (Study 1 and Study 2) and lesser use of task-oriented coping (Study 2), which reduced goal progress. These results held up after controlling for perceived stress (Study 2). Our findings highlight the importance of coping in the "inception-to-attainment" goal process because autonomous goal motivation indirectly rather than directly predicts goal progress of university students through their usage of task-oriented coping.

    To assess progress in the provision of drinking water and sanitation in relation to national socioeconomic indicators. We used household survey data for 73 countries - collected between 2000 and 2012 - to calculate linear rates of change in population access to improved drinking water (n = 67) and/or sanitation (n = 61). To enable comparison of progress between countries with different initial levels of access, the calculated rates of change were normalized to fall between -1 and 1. In regression analyses, we investigated associations between the normalized rates of change in population access and national socioeconomic indicators: gross national income per capita, government effectiveness, official development assistance, freshwater resources, education, poverty, Gini coefficient, child mortality and the human development index. The normalized rates of change indicated that most of the investigated countries were making progress towards achieving universal access to improved drinking water and sanitation. However, only about a third showed a level of progress that was at least half the maximum achievable level. The normalized rates of change did not appear to be correlated with any of the national indicators that we investigated. In many countries, the progress being made towards universal access to improved drinking water and sanitation is falling well short of the maximum achievable level. Progress does not appear to be correlated with a country's social and economic characteristics. The between-country variations observed in such progress may be linked to variations in government policies and in the institutional commitment and capacity needed to execute such policies effectively.

    We demonstrate that macromolecules in miscible polymer blends may behave as good, Θ, and poor polymeric solvents for each other. We construct a conceptual phase diagram, delineating the range of validity of the random-phase approximation, outside of which polymers contract or expand beyond their unperturbed dimensions, contrary to common assumptions. Remarkably, the correlation length for polymer blends, solutions, and supercritical mixtures collapses onto a master curve, reflecting universal behavior for macromolecules in polymeric and small-molecule Θ solvents

However, few studies have investigated what constitutive elements of the music had an effect on brain activity. As Canon chord progression is one of critical elements for pleasant melodies, we sought to examine the effects of Canon chord progression and pitch-shifted Canon chord progression on brain activity using performance on the auditory oddball task during event-related potentials (ERPs in 30 healthy subjects. Unexpectedly, we found no differences in ERP components between subjects listening to Canon chord progression (n=15 or pitch-shifted Canon chord progression (n=15. Next, we divided participants into two groups: those who found the melody pleasant (n=17 and those who did not (n=13, for both Canon chord progression and pitch-shifted Canon chord progression. The average of P300 amplitude was higher at Fz in subjects found the music pleasant versus those finding it unpleasant. Moreover, subjects who found it pleasant exhibited higher motivation scores than those who felt it was unpleasant, whereas listening to Canon chord progression did not matter. These findings suggest that the effects of Canon chord progression on brain activity and motivation depend on subjective feelings, not the chord progression per se.

    Jônadas Techio

    2012-12-01

    Full Text Available The paper supports a dialectical interpretation of Wittgenstein's method focusing on the analysis of the conditions of experience presented in his Philosophical Remarks. By means of a close reading of some key passages dealing with solipsism I will try to lay bare their self-subverting character: the fact that they amount to miniature dialectical exercises offering specific directions to pass from particular pieces of disguised nonsense to corresponding pieces of patent nonsense. Yet, in order to follow those directions one needs to allow oneself to become simultaneously tempted by and suspicious of their all-too-evident "metaphysical tone" - a tone which, as we shall see, is particularly manifest in those claims purporting to state what can or cannot be the case, and, still more particularly, those purporting to state what can or cannot be done in language or thought, thus leading to the view that there are some (determinate things which are ineffable or unthinkable. I conclude by suggesting that in writing those remarks Wittgenstein was still moved by an ethical project, which gets conspicuously displayed in these reiterations of his attempts to cure the readers (and himself from some of the temptations expressed by solipsism.

    This paper reports on the progress made over nearly a decade (1980-1990) by the Molecular Beam Group in the Complutense University of Madrid. After the author's stay in the United States as Prof. R.B Bernstein's post doc everything here had to be done from scratch. Designing the apparatus; importing all the equipment; overcoming huge bureaucracy: buying screws, welding, plumbing, etc. Essentially the following experimental techniques were set up: crossed-beam techniques to measure total and differential reaction cross-section for ground and/or excited species. Reaction Energy threshold and excitation functions for elementary chemical reactions. Molecular Beam chemiluminescence either in crossed-beam and beam-gas conditions. Laser-induced fluorescence and laser-induced charge transfer processes in beams and crossed-beam conditions, respectively. The chemiionization technique in crossed-beams was also set up. Our group pioneered: (a) the measurement of high resolution threshold energies and total reaction cross-section (also in absolute units) for many reactions; (b) the production of highly intense pulsed beams of electronically excited atoms; (c) the measurement under high resolution of the crossed-beam dynamics of excited species; (d) the measurement of the role of alkyl groups in the dynamics (stereodynamics) of chemical reactions; (e) the measurement of the spin-orbit effects in laser-induced charge transfer processes; (f) the developing of a novel technique, using the time-of-flight method under crossed-beam conditions, that is able to measure existing quantum effects in the total reaction cross-section; (g) the measurement of dissociation energies of radicals with less than 1% of experimental error.

  14. Remarks about the displaced spectra techniques

    International Nuclear Information System (INIS)

    Behringer, K.; Pineyro, J.

    1989-01-01

    In a recent paper a new method, called displaced spectra techniques, was presented for distinguishing between sinusoidal components and narrowband random noise contributions in otherwise random noise data. It is based on Fourier transform techniques, and uses the power spectral density (PSD) and a newly-introduced second-order displaced power spectra density (SDPSD) function. In order to distinguish between the two peak types, a validation criterion has been established. In this note, three topics are covered: a) improved numerical data for the validation criterion are given by using the refined estimation procedure of the PSD and SDPSD functions by the Welch method; b) the validation criterion requires the subtraction of the background below the peaks. A semiautomatic procedure is described; c) it was observed that peaks in the real part of the SDPSD function can be accompanied by fine structure phenomena which are unresolved in the PSD function. A few remarks are made about this problem. (author)

    2018-04-01

    In many branches of science, progress is being made by taking advantage of insights from other branches of science. Cosmology, the structure and evolution of the universe, is certainly an area that is currently beset by problems in understanding. We show here that the scientific insights from the studies of early childhood development, in particular, those of Piaget, give a new way of looking at the early universe. This new approach can not only be invaluable in undergraduate teaching, but can even be the basis of semi-quantitative predictions.

    Full Text Available Astrobiology looks at all aspects related to life in places other than the Earth, including its biomolecular building blocks and suitable environmental conditions. In the present article, a different approach is followed: a comparative analysis between Astronomy and Biology as discrete domains of science. Remarkable similarities exist between these two apparently widely separated and multidisciplinary fields. Both are driven, from beginning to end, by thermodynamics. Their evolution is studied to a very reasonable degree of accuracy, from beginning to the present day, by analyzing data which were “frozen” in the past. Yet we cannot predict where and how they will go from here. A major difference is that in Biology, unlike Astronomy, we can see and analyse the present (or, more accurately, the immediate past. While the Big Bang is widely accepted as the origin of our universe, the debate about its ultimate fate is far from settled. A plethora of cosmological models has been proposed, many involving the concept of a multiuniverse. The observation that the rate of expansion of the universe is apparently accelerating further boosts the discussion. Entropy may act as a driving force behind the increasing rate of expansion, with nothingness as the maximum possible entropy our universe gets. Using biological systems as an analogy and adopting a broad definition for life, we may speculate the existence of a living multiuniverse, capable of natural evolution, in which each individual universe spontaneously goes through birth, development, reproduction, aging and death. The possible roles of supermassive black holes (SMBHs and human-like intelligence on the future evolution of our universe are briefly discussed.

  4. Visiting the Gödel universe.

    Visualization of general relativity illustrates aspects of Einstein's insights into the curved nature of space and time to the expert as well as the layperson. One of the most interesting models which came up with Einstein's theory was developed by Kurt Gödel in 1949. The Gödel universe is a valid solution of Einstein's field equations, making it a possible physical description of our universe. It offers remarkable features like the existence of an optical horizon beyond which time travel is possible. Although we know that our universe is not a Gödel universe, it is interesting to visualize physical aspects of a world model resulting from a theory which is highly confirmed in scientific history. Standard techniques to adopt an egocentric point of view in a relativistic world model have shortcomings with respect to the time needed to render an image as well as difficulties in applying a direct illumination model. In this paper we want to face both issues to reduce the gap between common visualization standards and relativistic visualization. We will introduce two techniques to speed up recalculation of images by means of preprocessing and lookup tables and to increase image quality through a special optimization applicable to the Gödel universe. The first technique allows the physicist to understand the different effects of general relativity faster and better by generating images from existing datasets interactively. By using the intrinsic symmetries of Gödel's spacetime which are expressed by the Killing vector field, we are able to reduce the necessary calculations to simple cases using the second technique. This even makes it feasible to account for a direct illumination model during the rendering process. Although the presented methods are applied to Gödel's universe, they can also be extended to other manifolds, for example light propagation in moving dielectric media. Therefore, other areas of research can benefit from these generic improvements.

  7. Self-image and Missions of Universities: An Empirical Analysis of Japanese University Executives

    Directory of Open Access Journals (Sweden)

    Masataka Murasawa

    2014-05-01

    Full Text Available As universities in Japan gain institutional autonomy in managing internal organizations, independent of governmental control as a result of deregulation and decentralizing reforms, it is becoming increasingly important that the executives and administrators of each institution demonstrate clear and strategic vision and ideas to external stakeholders, in order to maintain financially robust operations and attractiveness of their institutions. This paper considers whether and how the self-image, mission, and vision of universities are perceived and internalized by the management of Japanese universities and empirically examines the determinants of shaping such individual perceptions. The result of our descriptive analysis indicates that the recent government policy to internationalize domestic universities has not shown much progress in the view of university executives in Japan. An increasing emphasis on the roles of serving local needs in research and teaching is rather pursued by these universities. Individual perceptions among Japanese university executives with regard to the missions and functional roles to be played by their institutions are influenced by managerial rank as well as the field of their academic training. A multiple regression analysis reveals that the economy of scale brought out by an expanded undergraduate student enrollment gradually slows down and decelerate executive perceptions, with regard to establishing a globally recognized status in research and teaching. Moreover, Japanese universities with a small proportion of graduate student enrollment, likely opted out from competitions for gaining a greater respect in the global community of higher education between 2005 and 2012. Finally, the management in universities granted with the same amount of external research funds in both studied years responded more passively in 2012 than did in 2005 on the self-assessment of whether having established a status as a global

  8. Unbound color, prefaced by remarks on baryon spectroscopy

    International Nuclear Information System (INIS)

    Greenberg, O.W.

    Theoretical and experimental issues related to the possibility that color is unbound are surveyed. This implies that quarks, gluons and other particles carrying color can exist as isolated objects. It is surprisingly difficult to distinguish models with unbound color from those in which color is permanently confined. None-the-less, the present situation seems discouraging for unbound color because there is no unambiguous support for it and because the crucial prediction of formation of a colored gluon in e + e - collisions has been ruled out wherever sufficient data exists. The above survey is prefaced by remarks on the symmetric quark model for baryon spectroscopy

    Livingstone's second mission site on the shore of Lake Malawi suffers very high rates of consequential lightning strikes. Comprehensive interviewing of victims and their relatives in seven Traditional Authorities in Nkhata Bay District, Malawi revealed that the annual rate of consequential strikes was 419/million, more than six times higher than that in other developing countries; the rate of deaths from lightning was 84/million/year, 5.4 times greater than the highest ever recorded. These remarkable figures reveal that lightning constitutes a significant stochastic source of mortality with potential life history consequences, but it should not deflect attention away from the more prominent causes of mortality in this rural area.

    According to the Big Bang Theory as we go back in time the Universe becomes progressively hotter and denser. This leads us to believe that the early Universe was filled with hot plasma of elementary particles. Among many questions concerning this phase of history of the Universe there are questions of existence and fate of magnetic monopoles and primordial black holes. Static solution of Einstein-Yang-Mills system may be used as a toy model for such a black hole. Using methods of field theory we will show that its existence and regularity depend crucially on the presence of fermions around it.

    2013-03-01

    In Alzheimer patients with a solid musical background, isolated case-reports have reported the maintenance of remarkable musical abilities despite clear difficulties in their verbal memory and linguistic functions. These reports have encouraged a number of scientists to undertake more systematic studies which would allow a rigorous approach to the analysis of musical memory in Alzheimer patients with no formal musical background. Although restricted in number, the latest data are controversial regarding preserved musical capacities in Alzheimer patients. Our current review of the literature addresses this topic and advances the hypothesis that the processes of musical memory are function of illness progression. In the earlier stages, the majority of evaluations concerned musical episodic memory and suggested a dysfunction of this memory whereas in the moderate and severe stages, musical semantic memory and implicit learning are the majority of investigations and seemed more resistant to Alzheimer disease. In summary, our current review bring to understand the memory circuits involved and highlight the necessity to adapted the investigational tools employed to conform with the severity of the signs and symptoms of progressive Alzheimer disease in order to demonstrate the preserved musical capacities.

    The aim of the present study was to investigate the effect of radiotherapy on the local progression of hormone-refractory prostate cancer. From 1986 to 1995, 38 patients were diagnosed with local progression without distant progression after hormonal therapy at Chiba University Hospital. Eleven cases were treated with irradiation for local progression. External beam irradiation was delivered to the prostate at a dose of 50-66.6 Gy. In patients treated with radiotherapy, the duration from initial treatment to local recurrence was 6-80 months (mean±SD: 33.9±22.9 months). The follow-up period after irradiation was 7-64 months (mean±SD: 25.4±18.8 months). Three and 5 year cause-specific survival rates from radiotherapy were 46.2 and 23.1%, respectively. Radiotherapy had a marked effect on symptoms associated with local progression and no patients suffered from the symptoms after the radiotherapy. Complications of radiotherapy were limited. In patients with hormone refractory local progression without distant progression, low morbidity, low mortality radiotherapy offers a variable therapy to other palliative treatments because radiotherapy is able to control local symptoms for a long period of time.

    A discussion of the ingredients necessary to make predictions concerning single and double spin measurements in large p/sub perpendicular to/ inclusive processes is presented. Remarks are made as to what might be expected and what might be learned from such measurements. Various models for the production of large p/sub perpendicular to/ mesons have quite different spin structure and hence can be expected to give differing predictions. However, it is not possible at this time to make quantitative calculations, and it is possible (not probable) that the interesting spin observables will be negligibly small

    Hawaii's annual Journey through the Universe program is a flagship Gemini public education and outreach event that engages the public, teachers, astronomers, engineers, thousands of local students and staff from all of the Mauna Kea Observatories. The program inspires, educates, and engages teachers, students, and their families as well as the community. From February 10-18, 2011, fifty-one astronomy educators from observatories on Mauna Kea and across the world visited over 6,500 students in 310 classrooms at 18 schools. Two family science events were held for over 2,500 people at the 'Imiloa Astronomy Education Center and the University of Hawaii at Hilo. The local Chamber of Commerce(s) held an appreciation celebration for the astronomers attended by over 170 members from the local government and business community. Now going into its eighth year in Hawaii, the 2012 Journey Through the Universe program will continue working with the observatories on Mauna Kea and with the NASA Lunar Science Institute (NLSI). As a new partner in our Journey program, NLSI will join the Journey team (Janice Harvey, Gemini Observatory, Journey Team Leader) and give an overview of the successes and future developments of this remarkable program and its growth. The future of America rests on our ability to train the next generation of scientists and engineers.

  4. Nuclear constraints on the age of the universe

    International Nuclear Information System (INIS)

    Schramm, D.N.

    1982-12-01

    In this paper a review is made of how one can use nuclear physics to put rather stringent limits on the age of the universe and thus the cosmic distance scale. As the other papers in this session have demonstrated there is some disagreement on the distance scale and thus the limits on the age of the universe (if the cosmological constant ν = 0). However, the disagreement is only over the last factor of 2, the basic timescale seems to really be remarkably well agreed upon. The universe is billions of years old - not thousands, not quintillions but bilions of years. That our universe has a finite age is philosophically intriguing. That we can estimate that age to a fair degree of accuracy is truly impressive. No single measurement of the time since the Big Bang gives a specific, unambiguous age. Fortunately, we have at our disposal several methods that together fix the age with surprising precision. In particular, as the other papers show, there are three totally independent techniques for estimating an age and a fourth technique which involves finding consistency of the other three in the framework of the standard Big Bang cosmological model. The three independent methods are: cosmological dynamics, the age of the oldest stars, and radioactive dating. This paper concentrates on the third of the three methods, as well as go into the consistency technique

  5. Radiative Cooling: Principles, Progress, and Potentials

    Science.gov (United States)

    Hossain, Md. Muntasir

    2016-01-01

    The recent progress on radiative cooling reveals its potential for applications in highly efficient passive cooling. This approach utilizes the maximized emission of infrared thermal radiation through the atmospheric window for releasing heat and minimized absorption of incoming atmospheric radiation. These simultaneous processes can lead to a device temperature substantially below the ambient temperature. Although the application of radiative cooling for nighttime cooling was demonstrated a few decades ago, significant cooling under direct sunlight has been achieved only recently, indicating its potential as a practical passive cooler during the day. In this article, the basic principles of radiative cooling and its performance characteristics for nonradiative contributions, solar radiation, and atmospheric conditions are discussed. The recent advancements over the traditional approaches and their material and structural characteristics are outlined. The key characteristics of the thermal radiators and solar reflectors of the current state‐of‐the‐art radiative coolers are evaluated and their benchmarks are remarked for the peak cooling ability. The scopes for further improvements on radiative cooling efficiency for optimized device characteristics are also theoretically estimated. PMID:27812478

  13. Universal self-similar dynamics of relativistic and nonrelativistic field theories near nonthermal fixed points

    Science.gov (United States)

    Piñeiro Orioli, Asier; Boguslavski, Kirill; Berges, Jürgen

    2015-07-01

    We investigate universal behavior of isolated many-body systems far from equilibrium, which is relevant for a wide range of applications from ultracold quantum gases to high-energy particle physics. The universality is based on the existence of nonthermal fixed points, which represent nonequilibrium attractor solutions with self-similar scaling behavior. The corresponding dynamic universality classes turn out to be remarkably large, encompassing both relativistic as well as nonrelativistic quantum and classical systems. For the examples of nonrelativistic (Gross-Pitaevskii) and relativistic scalar field theory with quartic self-interactions, we demonstrate that infrared scaling exponents as well as scaling functions agree. We perform two independent nonperturbative calculations, first by using classical-statistical lattice simulation techniques and second by applying a vertex-resummed kinetic theory. The latter extends kinetic descriptions to the nonperturbative regime of overoccupied modes. Our results open new perspectives to learn from experiments with cold atoms aspects about the dynamics during the early stages of our universe.

  14. Concluding remarks of international symposium on highly excited states in nuclear reactions

    Energy Technology Data Exchange (ETDEWEB)

    Bernstein, A. M.; Ikegami, H.; Muraoka, M. [eds.

    1980-01-01

    This is the concluding remarks in the international symposium on highly excited states in nuclear reactions. The remarks concentrate on the giant quadrupole states. In the framework of the distorted wave Born approximation (DWB), the differential cross section can be deduced. The relevant transition matrix elements are defined, and the quantities which are measured in inelastic hadron (h, h') reactions are shown. These are used to obtain both neutron and proton transition multipole matrix elements. This is equivalent to make the isospin decomposition of the electromagnetic transition matrix elements. The ratios of the transition matrix elements of neutrons and protons of the lowest 2/sup +/ states in even-even single closed shell nuclei are evaluated and compared with experimental results. For each nucleus, the consistency between various measurements is generally good. The effect of the virtual excitation of giant 2/sup +/ states into the ground and first excited states of even-even nuclei is discussed. The accuracy of (h, h') results can be tested.

    2014-04-01

    Full Text Available Due to frequent viral antigenic change, current influenza vaccines need to be re-formulated annually to match the circulating strains for battling seasonal influenza epidemics. These vaccines are also ineffective in preventing occasional outbreaks of new influenza pandemic viruses. All these challenges call for the development of universal influenza vaccines capable of conferring broad cross-protection against multiple subtypes of influenza A viruses. Facilitated by the advancement in modern molecular biology, delicate antigen design becomes one of the most effective factors for fulfilling such goals. Conserved epitopes residing in virus surface proteins including influenza matrix protein 2 and the stalk domain of the hemagglutinin draw general interest for improved antigen design. The present review summarizes the recent progress in such endeavors and also covers the encouraging progress in integrated antigen/adjuvant delivery and controlled release technology that facilitate the development of an affordable universal influenza vaccine.

    The authors comment on the talks given at the Torino Workshop on astrophysical jets. The observations presented have not revealed a clear picture of nuclear jets. Concerning large scale jets, people begin to find systematic patterns in the variety of parameters and morphologies. So, this kind of jets is paid most attention to during the Workshop. The authors discuss the general consensus in the basic parameters of jets arisen from the preliminary data. Propagation and confinement of jets, the role of magnetic fields, and some observational tests are briefly reviewed. A final paragraph deals with the origin and termination of jets. (G.J.P.)

  1. Promoting universal financial protection: evidence from seven low- and middle-income countries on factors facilitating or hindering progress.

    Although universal health coverage (UHC) is a global health policy priority, there remains limited evidence on UHC reforms in low- and middle-income countries (LMICs). This paper provides an overview of key insights from case studies in this thematic series, undertaken in seven LMICs (Costa Rica, Georgia, India, Malawi, Nigeria, Tanzania, and Thailand) at very different stages in the transition to UHC.These studies highlight the importance of increasing pre-payment funding through tax funding and sometimes mandatory insurance contributions when trying to improve financial protection by reducing out-of-pocket payments. Increased tax funding is particularly important if efforts are being made to extend financial protection to those outside formal-sector employment, raising questions about the value of pursuing contributory insurance schemes for this group. The prioritisation of insurance scheme coverage for civil servants in the first instance in some LMICs also raises questions about the most appropriate use of limited government funds.The diverse reforms in these countries provide some insights into experiences with policies targeted at the poor compared with universalist reform approaches. Countries that have made the greatest progress to UHC, such as Costa Rica and Thailand, made an explicit commitment to ensuring financial protection and access to needed care for the entire population as soon as possible, while this was not necessarily the case in countries adopting targeted reforms. There also tends to be less fragmentation in funding pools in countries adopting a universalist rather than targeting approach. Apart from limiting cross-subsidies, fragmentation of pools has contributed to differential benefit packages, leading to inequities in access to needed care and financial protection across population groups; once such differentials are entrenched, they are difficult to overcome. Capacity constraints, particularly in purchasing organisations, are a pervasive

    Cyclic models of the universe have the advantage of avoiding initial conditions problems related to postulating any sort of beginning in time. To date, the best known viable examples of cyclic models have been ekpyrotic. In this paper, we show that the recently proposed anamorphic scenario can also be made cyclic. The key to the cyclic completion is a classically stable, non-singular bounce. Remarkably, even though the bounce construction was originally developed to connect a period of contraction with a period of expansion both described by Einstein gravity, we show here that it can naturally be modified to connect an ordinary contracting phase described by Einstein gravity with a phase of anamorphic smoothing. The paper will present the basic principles and steps in constructing cyclic anamorphic models.

    2013-08-21

    Thiolated gold nanoclusters form a universe of their own. Researchers in this field are constantly pushing the boundary of this universe by identifying new compositions and in a few "lucky" cases, solving their structures. Such solved structures, even if there are only few, provide important hints for predicting the many identified compositions that are yet to be crystallized or structure determined. Structure prediction is the most pressing issue for a computational chemist in this field. The success of the density functional theory method in gauging the energetic ordering of isomers for thiolated gold clusters has been truly remarkable, but to predict the most stable structure for a given composition remains a great challenge. In this feature article from a computational chemist's point of view, the author shows how one understands and predicts structures for thiolated gold nanoclusters based on his old and new results. To further entertain the reader, the author also offers several "imaginative" structures, claims, and challenges for this field.

    The last 40 years have seen a remarkable increase in the teaching of neuroscience at the undergraduate level. From its origins as a component of anatomy or physiology departments to its current status as an independent interdisciplinary field, neuroscience has become the chosen field of study for many undergraduate students, particularly for those interested in medical school or graduate school in neuroscience or related fields. We examined how life science-based neuroscience education is offered at large public universities in the Western United States. By examining publicly available materials posted online, we found that neuroscience education may be offered as an independent program, or as a component of biological or physiological sciences at many institutions. Neuroscience programs offer a course of study involving a core series of courses and a collection of topical electives. Many programs provide the opportunity for independent research, or for laboratory-based training in neuroscience. Features of neuroscience programs at Western universities closely matched those seen at the top 25 public universities, as identified by U.S. News & World Report. While neuroscience programs were identified in many Western states, there were several states in which public universities appeared not to provide opportunities to major in neuroscience. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Current diagnostic criteria require the language dysfunction to remain isolated for at least two years, and to remain the salient feature as the disease progresses, usually to involve other domains such as behavior, executive functions, and judgment. Although PPA in its early stages can usually be differentiated from probable Alzheimer’s disease (PRAD and the behavioral variant of frontotemporal lobar degeneration by the absence of significant changes in memory and behavior, and the preservation of activities daily living, progression of the disease often leads to deficits more consistent with the latter. Underlying etiologies remain heterogeneous: the neuropathological characteristics associated with frontotemporal lobar degeneration, cortocobasal degeneration, and motor neuron disease are usually found. There is a strong genetic susceptibility with affliction of first-degree relatives with similar disease in up to 40 to 50% in some series. Pathogenic mutations in genes coding for the proteins tau and progranulin have been isolated. These are leading to a better understanding of the neuropathological mechanisms and hopefully targeted disease-modifying therapy. Current therapy is limited to improving mood symptoms and targeting behavior changes as they develop. Referral to specialized centers where speech therapy, counseling, and education

  15. Beyond the dynamical universe unifying block universe physics and time as experienced

    CERN Document Server

    Silberstein, Michael; McDevitt, Timothy

    2018-01-01

    Theoretical physics and foundations of physics have not made much progress in the last few decades. Whether we are talking about unifying general relativity and quantum field theory (quantum gravity), explaining so-called dark energy and dark matter (cosmology), or the interpretation and implications of quantum mechanics and relativity, there is no consensus in sight. In addition, both enterprises are deeply puzzled about various facets of time including above all, time as experienced. The authors argue that, across the board, this impasse is the result of the "dynamical universe paradigm," the idea that reality is fundamentally made up of physical entities that evolve in time from some initial state according to dynamical laws. Thus, in the dynamical universe, the initial conditions plus the dynamical laws explain everything else going exclusively forward in time. In cosmology, for example, the initial conditions reside in the Big Bang and the dynamical law is supplied by general relativity. Accordingly, th...

    More than forty years have passed since the discovery of Mossbauer effect; one of the most brilliant findings in modern physics. This effect proved itself to be the powerful tool in almost all disciplines of the natural sciences and technology. Its unique feature is that it gives the possibility to get the results which cannot be obtained by any other physical methods. Mossbauer effect has been used as a key to unlock some basic physical, chemical and biological phenomena, as a guide for finding the new ways of solving applied scientific and technical problems of electronics, metallurgy, civil engineering, and even fine arts and archaeology. Very few scientific techniques can claim entry into as many countries as Mossbauer spectroscopy. Due to its wide application in an education and research processes the community of Mossbauer spectroscopists extends to almost 100 different countries. Laboratory equipment necessary for conducting gamma resonance spectroscopy, do not require large investments, premises, personnel. The spectrometer is rather small in size and could be installed on the ordinary laboratory table. That is why Mossbauer effect is widely used at numerous Universities all over the world as an universal instrument for tuition and research

  19. Remarks on theoretical hot-atom chemistry

    International Nuclear Information System (INIS)

    Inokuti, Mitio

    1993-01-01

    The publication of the 'Handbook of Hot Atom Chemistry', following the earlier volume 'Recent Trend and Application', was a major milestone in physical chemistry. Theoretical treatments of hot atom chemistry must address two classes of problems. The first class concerns the individual collisions of hot atoms with other atoms or molecules. The second class concerns the description of the consequences of the many collisions of hot atoms and their chemical environment. Most of the remarks pertain to the problems of the first class. The central issue is the adiabaticity of nuclear motions versus electronic motions. To be precise, any atomic core motion should be mentioned rather than pure nuclear motion, because tightly bound core electrons are largely irrelevant to the chemistry. When nuclear motions are sufficiently slow, or for other reasons that can be regarded as adiabatic, the collision problem is basically straightforward, therefore, interatomic and intermolecular forces can be assumed, and their consequences for nuclear motions are calculable in principle. In the case of non-adiabaticity being important, much more difficult problems arise, and it is briefly discussed, and the work by Phelps is cited. (K.I.)

  20. Universality and Quantum Criticality of the One-Dimensional Spinor Bose Gas

    Science.gov (United States)

    PâÅ£u, Ovidiu I.; Klümper, Andreas; Foerster, Angela

    2018-06-01

    We investigate the universal thermodynamics of the two-component one-dimensional Bose gas with contact interactions in the vicinity of the quantum critical point separating the vacuum and the ferromagnetic liquid regime. We find that the quantum critical region belongs to the universality class of the spin-degenerate impenetrable particle gas which, surprisingly, is very different from the single-component case and identify its boundaries with the peaks of the specific heat. In addition, we show that the compressibility Wilson ratio, which quantifies the relative strength of thermal and quantum fluctuations, serves as a good discriminator of the quantum regimes near the quantum critical point. Remarkably, in the Tonks-Girardeau regime, the universal contact develops a pronounced minimum, reflected in a counterintuitive narrowing of the momentum distribution as we increase the temperature. This momentum reconstruction, also present at low and intermediate momenta, signals the transition from the ferromagnetic to the spin-incoherent Luttinger liquid phase and can be detected in current experiments with ultracold atomic gases in optical lattices.

    International Nuclear Information System (INIS)

    2012-01-01

    The focus of this research project was atoms with scattering lengths that are large compared to the range of their interactions and which therefore exhibit universal behavior at sufficiently low energies. Recent dramatic advances in cooling atoms and in manipulating their scattering lengths have made this phenomenon of practical importance for controlling ultracold atoms and molecules. This research project was aimed at developing a systematically improvable method for calculating few-body observables for atoms with large scattering lengths starting from the universal results as a first approximation. Significant progress towards this goal was made during the five years of the project.

No treatment has been available for the women suffering from an absent or dysfunctional uterus, in terms of carrying a pregnancy. Approximately one in 500 women suffer from absolute uterine infertility, and the option so far to become a mother has been to either adopt or utilize gestational surrogacy. As of today, a total of eleven cases of human uterus transplantations have been reported worldwide, conducted in three different countries. The results of these initial experimental cases far exceed what might be expected of a novel surgical method. Many more uterus transplantations are to be expected in the near future, as other research teams’ preparations are being ready to be put into clinical practice. In this review, we summarize the current worldwide experience of uterus transplantation as a treatment of absolute uterine factor infertility and the future prospects of human uterus transplantation.

  5. Ceramic Technology Project, semiannual progress report for October 1993 through March 1994

    Johnson, D.R.

    1994-09-01

    The Ceramic Technology Project was originally developed by the Department of Energy`s Office of Transportation Systems (OTS) in Conservation and Renewable Energy. Significant accomplishments in fabricating ceramic components for the Department of Energy (DOE), National Aeronautics and Space Administration (NASA), and Department of Defense (DoD) advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. An assessment of needs was completed, and a five-year project plan was developed with extensive input from private industry. In July 1990, the original plan was updated through the estimated completion of development in 1993. The original objective of the project was to develop the industrial technology base required for reliable ceramics for application in advanced automotive heat engines. During the course of the Ceramic Technology Project, remarkable progress has been made in the development of reliable structural ceramics. The direction of the Ceramic Technology Project is now shifting toward reducing the cost of ceramics to facilitate commercial introduction of ceramic components for near-term engine applications. In response to extensive input from industry, the plan is to extend the engine types which were previously supported (advanced gas turbine and low-heat-rejection diesel engines) to include near-term (5-10 years) applications in conventional automobile and diesel truck engines. To facilitate the rapid transfer of this technology to U.S. industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities. A systematic approach to reducing the cost of components is envisioned.

  6. Can specific transcriptional regulators assemble a universal cancer signature?

    2013-10-01

    Recently, there is a lot of interest in using biomarker signatures derived from gene expression data to predict cancer progression. We assembled signatures of 25 published datasets covering 13 types of cancers. How do these signatures compare with each other? On one hand signatures answering the same biological question should overlap, whereas signatures predicting different cancer types should differ. On the other hand, there could also be a Universal Cancer Signature that is predictive independently of the cancer type. Initially, we generate signatures for all datasets using classical approaches such as t-test and fold change and then, we explore signatures resulting from a network-based method, that applies the random surfer model of Google's PageRank algorithm. We show that the signatures as published by the authors and the signatures generated with classical methods do not overlap - not even for the same cancer type - whereas the network-based signatures strongly overlap. Selecting 10 out of 37 universal cancer genes gives the optimal prediction for all cancers thus taking a first step towards a Universal Cancer Signature. We furthermore analyze and discuss the involved genes in terms of the Hallmarks of cancer and in particular single out SP1, JUN/FOS and NFKB1 and examine their specific role in cancer progression.

    Bahcall, John; Fisher, Karl; Miralda-Escude, Jordi; Strauss, Michael; Weinberg, David

    1997-01-01

    This grant supported research by the investigators through summer salary support for Strauss and Weinberg, support for graduate students at Princeton University and Ohio State University, and travel, visitor, and publication support for the investigators. The grant originally had a duration of 1 year, and it was extended (without additional funding) for an additional year. The impact of the grant was considerable given its relatively modest duration and funding level, in part because it provided 'seed' funding to get Strauss and Weinberg started at new institutions, and in part because it was combined with support from subsequent grants. Here we summarize progress in the three general areas described in the grant proposal: Lyman alpha absorbers and the intergalactic medium, galaxy formation; and large scale structure.

    Full Text Available We study the modified Friedmann equation in the Friedmann-Robertson-Walker universe with quantum effect. Our modified results mainly stem from the new entropy-area relation and the novel idea of Padmanabhan, who considers the cosmic space to be emerging as the cosmic time progresses, so that the expansion rate of the universe is determined by the difference of degrees of freedom between the holographic surface and the bulk inside. We also discuss the possibility of having bounce cosmological solution from the modified Friedmann equation in spatially flat geometry.

    The striking resemblance of long-snouted aquatic mammals and reptiles has long been considered an example of morphological convergence, yet the true cause of this similarity remains untested. We addressed this deficit through three-dimensional morphometric analysis of the full diversity of crocodilian and toothed whale (Odontoceti) skull shapes. Our focus on biomechanically important aspects of shape allowed us to overcome difficulties involved in comparing mammals and reptiles, which have fundamental differences in the number and position of skull bones. We examined whether diet, habitat and prey size correlated with skull shape using phylogenetically informed statistical procedures. Crocodilians and toothed whales have a similar range of skull shapes, varying from extremely short and broad to extremely elongate. This spectrum of shapes represented more of the total variation in our dataset than between phylogenetic groups. The most elongate species (river dolphins and gharials) are extremely convergent in skull shape, clustering outside of the range of the other taxa. Our results suggest the remarkable convergence between long-snouted river dolphins and gharials is driven by diet rather than physical factors intrinsic to riverine environments. Despite diverging approximately 288 million years ago, crocodilians and odontocetes have evolved a remarkably similar morphological solution to feeding on similar prey. © 2017 The Author(s).

  10. Nuclear Physics Laboratory, University of Colorado technical progress report, 1976 and proposal for continuation of contract

    International Nuclear Information System (INIS)

    1976-01-01

    This report summarizes the work carried out at the Nuclear Physics Laboratory of the University of Colorado during the period November 1, 1975 to November 1, 1976. The low energy nuclear physics section is dominated by light-ion reaction studies which span a wide range. These include both two-neutron and two-proton transfer reactions, charge exchange and inelastic scattering, as well as single nucleon transfer reactions. The nuclei studied vary widely in their mass and characteristics. These reaction studies have been aided by the multi-use scattering chamber which now allows the energy-loss-spectrometer beam preparation system (beam swinger) to shift from charged particle studies to neutron time-of-flight studies with a minimum loss of time. The intermediate energy section reflects the increase in activity accompanying the arrival of LAMPF data and the initiation of (p,d) studies at the Indiana separated-sector cyclotron. The nucleon removal results provided by the π beam at EPICS previous to completion of the spectrometer have shown that nuclear effects dominate this process, so that the widely used free interaction picture is inadequate. The section entitled ''Other Activities'' reveals continuing activities in new applications of nuclear techniques to problems in medicine and biology. Reactions important to astrophysics continue to be investigated and our trace-element program remains at a high level of activity. The theoretical section reports new progress in understanding magnitudes of two-step reactions by inclusion of finite-range effects. A new finite-range program which is fast and economical has been completed. Intermediate energy results include calculations of π-γ angular correlations, low energy π-nucleus interactions, as well as (p,d) and nucleon scattering calculations for intermediate energies

  11. Moral Progress: A Present-day Perspective on the Leading Enlightenment Idea

    Directory of Open Access Journals (Sweden)

    Andrzej Elżanowski

    2013-06-01

    Full Text Available Most Enlightenment thinkers believed that the World’s order (as ultimately based on divine laws is good and thus every gain of knowledge will have good consequences. Scientific process was assumed to entail moral progress. In fact some moral progress did occur in the Western civilization and science contributed to it, but it is widely incommensurate with the progress of science. The Enlightenment’s concept of a concerted scientific and moral progress proved largely wrong for several reasons. (1 Public morality and science evolve largely independently and may either enhance or inhibit each other. (2 There are no objective values to be read in the World’s order and simply followed. Instead, our real, subjective values and the moral systems they fuel have all been generated and shaped by evolution rather than designed to be universally good, and thus ought to be managed rather than simply followed. (3 Our evolved morality is flawed, deficient, prone to doctrinal manipulation and refractory to progress. (4 The majority of people show metaethical incompetence in failing to take a reasoned critical stand toward the principles and assumptions of received morals. This makes moral progress largely dependent on those who reach metaethical competence by transcending the conventional stages of moral development.

    Winston, Roland

    Of the variety of solar energy conversion schemes that have been explored, the conversion of solar flux to coherent laser radiation is relatively new. Solar flux at sufficiently high concentrations to overcome threshold for the really important laser materials has not been available. This technological inhibition has recently been overcome through the application of nonimaging optics through the demonstration of concentration levels of 84,000 suns at the University of Chicago in a refractive medium (sapphire) and of over 20,000 suns in air at the Solar Energy Research Institute High Flux Facility. A thermodynamic overview is presented of solar lasers including solid state lasers and dye lasers.

    Full Text Available With the progress of times, our spiritual pursuit becomes higher and higher, and it is especially true among modern youth. Therefore, establishment of university culture has gradually become the focus of attention. This paper firstly quantized university culture construction into four parts: material culture construction, spiritual culture construction, system culture construction, and behavioral culture construction. It then analogized each part as one population in ecological system; established multi-population ecological model; and analyzed the interactional relations between each part. At last, this paper reached conclusions based on multi-population ecological model and analyzed the correlations among various factors of university culture construction, so as to obtain a comprehensive, scientific and healthy scheme for university culture construction.

    We investigated the research publications on thermal spray in the period of 1985-2015 using the data from Web of Science, Scopus and SciVal®. Bibliometrics analysis was employed to elucidate the country and institution distribution in various thermal spray research areas and to characterize the trends of topic change and technology progress. Results show that China, USA, Japan, Germany, India and France were the top countries in thermal spray research, and Xi'an Jiaotong University, Universite de Technologie Belfort-Montbeliard, Shanghai Institute of Ceramics, ETH Zurich, National Research Council of Canada, University of Limoges were among the top institutions that had high scholarly research output during 2005-2015. The terms of the titles, keywords and abstracts of the publications were analyzed by the Latent Dirichlet Allocation model and visually mapped using the VOSviewer software to reveal the progress of thermal spray technology. It is found that thermal barrier coating was consistently the main research area in thermal spray, and high-velocity oxy-fuel spray and cold spray developed rapidly in the last 10 years.

    2015-10-01

    Full Text Available The middle-income trap is an economic phenomenon to describe economies that have stagnated at the middle-income level and failed to progress into the high-income level. Inspired by this economic concept, this paper explores a hypothesis: is there a 'mid-rank trap' for universities in the exercise to rank universities globally' Using the rankings between 2004 and 2014 that were jointly and separately developed by Times Higher Education and Quacquarelli Symonds Company, this paper argues that there is indeed a phenomenon, which I term as 'mid-rank trap' whereby universities remain stagnant for a decade in a similar band of the rankings. Having established the hypothesis for universities, the paper examines policies and interventions that have been successfully carried out to elevate economies away from the middle-income trap, and importantly, to draw out the underlying principles of these economic policies and interventions that can be incorporated into policymaking and strategic planning for universities using the Malaysian higher education system as a case study.

    Attendees are welcomed to the conference. The general scope of the problem is touched on, and the driving point is made, that the development of new technology is necessary to meet the environmental restoration goals for the Hanford Reservation with a reasonable expenditure of funds and resources. If present technology in treating radioactive waste has to be applied to the wastes prior to final disposal, then the processing costs, and the resultant disposal costs, because of the volume of material to be disposed of, will be tremendous. This conference brings together researchers from national laboratories, universities, and industry to present the scope of the problem, the present status of separation science, and to encourage new technological development

    Astrobiology looks at all aspects related to life in places other than the Earth, including its biomolecular building blocks and suitable environmental conditions. In the present article, a different approach is followed: a comparative analysis between Astronomy and Biology as discrete domains of science. Remarkable similarities exist between these two apparently widely separated and multidisciplinary fields. Both are driven, from beginning to end, by thermodynamics. Their evolution is studied to a very reasonable degree of accuracy, from beginning to the present day, by analyzing data which were “frozen” in the past. Yet we cannot predict where and how they will go from here. A major difference is that in Biology, unlike Astronomy, we can see and analyse the present (or, more accurately, the immediate past). While the Big Bang is widely accepted as the origin of our universe, the debate about its ultimate fate is far from settled. A plethora of cosmological models has been proposed, many involving the concept of a multiuniverse. The observation that the rate of expansion of the universe is apparently accelerating further boosts the discussion. Entropy may act as a driving force behind the increasing rate of expansion, with nothingness as the maximum possible entropy our universe gets. Using biological systems as an analogy and adopting a broad definition for life, we may speculate the existence of a living multiuniverse, capable of natural evolution, in which each individual universe spontaneously goes through birth, development, reproduction, aging and death. The possible roles of supermassive black holes (SMBHs) and human-like intelligence on the future evolution of our universe are briefly discussed.

    2014-05-01

    The 2007 Flood Directive promotes the integration and valorization of historical and significant floods in flood risk management (Flood Directive Text, chapter II, and article 4). Taking into account extreme past floods analysis seems necessary in the mitigation process of vulnerability face to flooding risk. In France, this aspect of the Directive was carried out through the elaboration of Preliminary Flood Risk Assessment (PFRA) and the establishment of a 2000 floods list. From this first list, a sample of 176 floods, considered as remarkable has been selected. These floods were compiled in discussion with local authorities in charge of flood management (Lang et al., 2012) and have to be integrated in priority in local risk management policies. However, a consideration emerges about this classification: how a remarkable flood can be defined? According which criteria can it be considered as remarkable? To answer these questions, a methodology has been established by building an evaluation grid of remarkable floods in France. The primary objective of this grid is to analyze the remarkable flood's characteristics (hydrological and meteorological characteristics, sociological- political and economic impacts), and secondly to propose a classification of significant floods selected in the 2011 PFRA. To elaborate this evaluation grid, several issues had to be taken into account. First, the objective is to allow the comparison of events from various periods. These temporal disparities include the integration of various kinds of data and point out the importance of historical hydrology. It is possible to evaluate accurately the characteristics of recent floods by interpreting quantitative data (for example hydrological records. However, for floods that occurred before the 1960's it is necessary resorting to qualitative information such as written sources is necessary (Coeur, Lang, 2008). In a second part the evaluation grid requires equitable criteria in order not to

    Full Text Available This article aims at exploring the great influence of Ibsen and especially his play A Doll House on the young Chinese girls studying at Peking Women’s High Normal University established for the first time in China at the beginning of the 20th century to educate girls. In its short history, the girls at the university were exposed widely to the progressive ideas and literature from the West. Ibsen, the most popular writer at that time, inspired the girls tremendously whose performance of A Doll House aroused a heated debate among the well-known scholars on such important issues as women’s rights, women’s liberation, new culture, art and literature. Consequently there appeared at the university first group of modern Chinese women writers who picked up their pens and wrote about themselves and about women in China, describing themselves as “Chinese Noras”.

  8. The universality of the Carnot theorem

    International Nuclear Information System (INIS)

    Gonzalez-Ayala, Julian; Angulo-Brown, F

    2013-01-01

    It is common in many thermodynamics textbooks to illustrate the Carnot theorem through the use of diverse state equations for gases, paramagnets, and other simple thermodynamic systems. As is well known, the universality of the Carnot efficiency is easily demonstrated in a temperature–entropy diagram, which means that η C is independent of the working substance. In this paper we remark that the universality of the Carnot theorem goes beyond conventional state equations, and is fulfilled by gas state equations that do not correspond to an ideal gas in the dilution limit, namely V → ∞. Some of these unconventional state equations have certain thermodynamic ‘anomalies’ that nonetheless do not forbid them from obeying the Carnot theorem. We discuss how this very general behaviour arises from Maxwell relations, which are connected with a geometrical property expressed through preserving area transformations. A rule is proposed to calculate the Maxwell relations associated with a thermodynamic system by using the preserving area relationships. In this way it is possible to calculate the number of possible preserving area mappings by giving the number of possible Jacobian identities between all pairs of thermodynamic variables included in the corresponding Gibbs equation. This paper is intended for undergraduates and specialists in thermodynamics and related areas. (paper)

    Full Text Available The remarkable progress in engineering and clinical development of therapeutic antibodies in the last 40 years, after the seminal work by Köhler and Milstein, has led to the approval by the United States Food and Drug Administration (FDA of 21 antibodies for cancer immunotherapy. We review here these approved antibodies, with emphasis on the methods used for their discovery, engineering, and optimization for therapeutic settings. These methods include antibody engineering via chimerization and humanization of non-human antibodies, as well as selection and further optimization of fully human antibodies isolated from human antibody phage-displayed libraries and immunization of transgenic mice capable of generating human antibodies. These technology platforms have progressively led to the development of therapeutic antibodies with higher human content and, thus, less immunogenicity. We also discuss the genetic engineering approaches that have allowed isotype switching and Fc modifications to modulate effector functions and bioavailability (half-life, which together with the technologies for engineering the Fv fragment, have been pivotal in generating more efficacious and better tolerated therapeutic antibodies to treat cancer.

    Science and engineering doctoral students performing energy related research were supported by a USDOE/ESPCoR Traineeship grant awarded to the Kentucky EPSCoR Committee. The grant, administered by the KY DOE/EPSCoR Subcommittee, focused on research having the general description of {open_quotes}Clean Uses of Fossil Fuels{close_quotes}. The value of the grant was $500,000 for three years duration, beginning September 30, 1991 and ending September 29, 1994. Ten PhD students were selected for support during the first year of the Traineeship. Upon reviewing coursework and research progress of the students at the end of the first year, the KY DOE/EPSCoR Subcommittee awarded a second year of support at the same $25,000/year funding level. A total of 12 students will have been supported during the duration of the grant as a consequence of one student completing his degree during the support period and of one student deciding that she wanted to complete only a Masters rather than a PhD degree. The students supported were at either the University of Kentucky or the University of Louisville - the two PhD, science and engineering granting universities within the Commonwealth of Kentucky. The disciplines of these students included Biology, Chemical Engineering, Chemistry, Geological Sciences, and Physics. The methods used for the initial statewide solicitation for student support, the annual review of the students progress for support renewal, and a summary of progress and impact of the awards after two years are presented. It is shown that the Traineeships presented opportunities to: perform high quality research; initiate interactions between different scientific disciplines and departments; develop collaborations at national DOE laboratories, universities outside of Kentucky and industries; and establish research ideas for submittal to funding agencies.

    Full Text Available Student attrition has been a primary focus among higher education institutions for nearly 50 years, yet overall retention and graduation rates continue to be of significant concern. Despite increased attention, ongoing struggles of colleges and universities to effectively address potential barriers to student progress are well-documented.  Part of the challenge lies in garnering widespread organizational commitment that establishes student progress as an institutional priority.  Along with leadership commitment, broad institutional involvement and adherence to a systematic approach to testing new, innovative solutions are necessary to better position the institution to make clear, evidence-based decisions that improve the student experience. The purpose of this manuscript is to detail one university’s cultural shift towards establishing a clear student progress strategy (with particular focus on the first year, and the methodological approach that laid the foundation for a multi-year study of initiatives that resulted in improved student satisfaction, performance, and retention.

    Carrying a spirit of a long history of cooperation in physics education and research between Fisk University and Vanderbilt University, the Nuclear Research Program in the Department of Physics at Fisk University was proposed in 1996 in cooperation with the Nuclear Physics Group at Vanderbilt University. An initial NRP program was commissioned in 1997 with the financial support from DOE. The program offers a great opportunity for students and faculty at Fisk University to directly access experimental nuclear data and analyzing facilities within the Nuclear Physics Group at Vanderbilt University for a quick start. During the program Fisk Faculty and students (along with the colleagues at Vanderbilt University) have achieved progress in a few areas. We have (a) established an in-house nuclear data processing and analysis program at Fisk University, (b) conducted hands-on nuclear physics experiments for a Fisk undergraduate student at Vanderbilt University, (c) participated in the UNIRIB research with radioactive ion beam and Recoil Mass Spectrometer at Oak Ridge National Laboratory, and (d) studied {sup 252}Cf spontaneous fission and in-beam nuclear reactions for exotic nuclei. Additionally, this work has produced publication in conference proceedings as well as referred journals. [2-7].

    Low-grade gliomas often undergo malignant progression, and these transformations are a leading cause of death in patients with low-grade gliomas. However, the molecular mechanisms underlying malignant tumor progression are still not well understood. Recent evidence indicates that epigenetic deregulation is an important cause of gliomagenesis; therefore, we examined the impact of epigenetic changes during malignant progression of low-grade gliomas. Specifically, we used the Illumina Infinium Human Methylation 450K BeadChip to perform genome-wide DNA methylation analysis of 120 gliomas and four normal brains. This study sample included 25 matched-pairs of initial low-grade gliomas and recurrent tumors (temporal heterogeneity) and 20 of the 25 recurring tumors recurred as malignant progressions, and one matched-pair of newly emerging malignant lesions and pre-existing lesions (spatial heterogeneity). Analyses of methylation profiles demonstrated that most low-grade gliomas in our sample (43/51; 84%) had a CpG island methylator phenotype (G-CIMP). Remarkably, approximately 50% of secondary glioblastomas that had progressed from low-grade tumors with the G-CIMP status exhibited a characteristic partial demethylation of genomic DNA during malignant progression, but other recurrent gliomas showed no apparent change in DNA methylation pattern. Interestingly, we found that most loci that were demethylated during malignant progression were located outside of CpG islands. The information of histone modifications patterns in normal human astrocytes and embryonal stem cells also showed that the ratio of active marks at the site corresponding to DNA demethylated loci in G-CIMP-demethylated tumors was significantly lower; this finding indicated that most demethylated loci in G-CIMP-demethylated tumors were likely transcriptionally inactive. A small number of the genes that were upregulated and had demethylated CpG islands were associated with cell cycle-related pathway. In

    Full Text Available Liver cancer is the third most common cancer type and the second leading cause of deaths in men. Large population studies have demonstrated remarkable gender disparities in the incidence and the cumulative risk of liver cancer. A number of emerging risk factors regarding metabolic alterations associated with obesity, diabetes and dyslipidemia have been ascribed to the progression of non-alcoholic fatty liver diseases (NAFLD and ultimately liver cancer. The deregulation of fat metabolism derived from excessive insulin, glucose and lipid promotes cancer-causing inflammatory signaling and oxidative stress, which eventually triggers the uncontrolled hepatocellular proliferation. This review presents the current standing on the gender differences in body fat compositions and their mechanistic linkage with the development of NAFLD-related liver cancer, with an emphasis on genetic, epigenetic and microRNA control. The potential roles of sex hormones in instructing adipocyte metabolic programs may help unravel the mechanisms underlying gender dimorphism in liver cancer and identify the metabolic targets for disease management.

  2. Tertiary alphabet for the observable protein structural universe.

    Mackenzie, Craig O; Zhou, Jianfu; Grigoryan, Gevorg

    2016-11-22

    Here, we systematically decompose the known protein structural universe into its basic elements, which we dub tertiary structural motifs (TERMs). A TERM is a compact backbone fragment that captures the secondary, tertiary, and quaternary environments around a given residue, comprising one or more disjoint segments (three on average). We seek the set of universal TERMs that capture all structure in the Protein Data Bank (PDB), finding remarkable degeneracy. Only ∼600 TERMs are sufficient to describe 50% of the PDB at sub-Angstrom resolution. However, more rare geometries also exist, and the overall structural coverage grows logarithmically with the number of TERMs. We go on to show that universal TERMs provide an effective mapping between sequence and structure. We demonstrate that TERM-based statistics alone are sufficient to recapitulate close-to-native sequences given either NMR or X-ray backbones. Furthermore, sequence variability predicted from TERM data agrees closely with evolutionary variation. Finally, locations of TERMs in protein chains can be predicted from sequence alone based on sequence signatures emergent from TERM instances in the PDB. For multisegment motifs, this method identifies spatially adjacent fragments that are not contiguous in sequence-a major bottleneck in structure prediction. Although all TERMs recur in diverse proteins, some appear specialized for certain functions, such as interface formation, metal coordination, or even water binding. Structural biology has benefited greatly from previously observed degeneracies in structure. The decomposition of the known structural universe into a finite set of compact TERMs offers exciting opportunities toward better understanding, design, and prediction of protein structure.

    2014-04-01

    Full Text Available The task of the university professor is a mission and not simply a profession and that is why higher education should be impregnated with values. Nowadays education is articulated into three areas: the State, the Market and the Volunteering, but no one of these three sectors by themselves has covered the needs of all the citizens, there have always been losers, therefore the conjunction of the three sectors became necessary. Communitarianism promotes an ethical-social pact that favors the progress of society without nullifying the individual dimension. It believes that the university is the space where a communitarian consciousness should be promoted to generate a social capital by means of education and it is a privilege place to substantiate the moral identity of the person beginning with the commitment of the professor with the university student.

    2010-01-01

    Meeting the challenges of diversity is crucial, and within healthcare organizations a particularly strong case exists for a diversity strategy. Rush University Medical Center in 2006 was at an important juncture. Since its founding, the organization had made notable progress toward advancing diversity and inclusiveness. On the other hand, many diversity-related problems continued. Rush convened a committee to review the work of the institution in this area. The committee's report called for changes, and a Diversity Leadership Group (DLG) model was established. This article documents the progress made since 2006 through implementation of the DLG model. The changes prescribed for Rush are presented as recommendations and challenges that other healthcare organizations may find applicable to their own institutions.

    2001-10-19

    The QUALIT grant funded two broad categories of work: (1) Project-wide QBone engineering, instrumentation, and integration; (2) Focused workshops and measurement work relating specifically to advanced university/DOE connectivity. Significant progress has been made in both areas and, to both, QUALIT funding has been a key enabling resource. This final report summarizes the accomplishments of the QUALIT project and explains changes to the technical focus of the project that, while significant, remained true to the overall project goal: to research, test, and deploy IP layer traffic differentiation to redress congestion-related end-to-end performance problems on key university-DOE lab paths.

    longitudinal grey matter changes in the non-fluent/agrammatic variant of primary progressive aphasia. Graph theoretical analysis of the speech/language network showed that regions with shorter functional paths to the epicentre exhibited greater longitudinal atrophy. The network contained three modules, including a left inferior frontal gyrus/supplementary motor area, which was most strongly connected with the epicentre. The aslant tract was the white matter pathway connecting these two regions and showed the most significant correlation between fractional anisotropy and white matter longitudinal atrophy changes. This study showed that the pattern of longitudinal atrophy progression in the non-fluent/agrammatic variant of primary progressive aphasia relates to the strength of connectivity in pre-determined functional and structural large-scale speech production networks. These findings support the hypothesis that the spread of neurodegeneration occurs by following specific anatomical and functional neuronal network architectures. © The Author (2016).

    The set-up of a relativistic constituent quark model in four dimensions is one of the outstanding problems in particle physics. For the time being this involves a great deal of model building which, very probably, will not change in the near future. In this paper we shall offer some general remarks which might help putting such models into shape. Most of the earlier attempts are found controversial. In particular, a conventional quark constituent interpretation could not be recovered. (orig.) [de

    Cosmology is the scientific study of how the Universe began more than 13 billion years ago, how its properties have changed from that time to the present, and what its eventual fate might be. Observational cosmology uses telescopes like the Hubble to reach back in time to find the faint echoes of the Big Bang. In this lecture, I will give an overview of cosmology, highlighting the very rapid progress this field has made in the last decade, and the role that NASA space telescopes have played and will continue to play in the years to come. I will then focus on two of the most intriguing of those recent discoveries: inflation and dark energy. Our universe began in an extremely rapid accelerated expansion, called inflation, which removed all traces anything that may have existed before, flattened the geometry of space-time, and turned microscopic quantum fluctuations into the largest structures in the universe. At the present time, more than 70% of the mass-energy in the Universe consists of a mysterious substance called dark energy. The dark energy causes the expansion of the Universe to accelerate, and he will discuss the ways that we might be able to measure that acceleration more accurately, revealing the nature of the dark energy and learning the eventual fate of the Universe.

    2010-01-01

    Retinal diseases such as age-related macular degeneration and retinitis pigmentosa remain major causes of severe vision loss in humans. Clinical trials for treatment of retinal degenerations are underway and advancements in our understanding of retinal biology in health/disease have implications for novel therapies. A review of retinal biology is used to inform a discussion of current strategies to maintain/repair neural circuitry in age-related macular degeneration, retinitis pigmentosa, and Type 2 Leber congenital amaurosis. In age-related macular degeneration/retinitis pigmentosa, a progressive loss of rods/cones results in corruption of bipolar cell circuitry, although retinal output neurons/photoreceptive melanopsin cells survive. Visual function can be stabilized/enhanced after treatment in age-related macular degeneration, but in advanced degenerations, reorganization of retinal circuitry may preclude attempts to restore cone function. In Type 2 Leber congenital amaurosis, useful vision can be restored by gene therapy where central cones survive. Remarkable progress has been made in restoring vision to rodents using light-responsive ion channels inserted into bipolar cells/retinal ganglion cells. Advances in genetic, cellular, and prosthetic therapies show varying degrees of promise for treating retinal degenerations. While functional benefits can be obtained after early therapeutic interventions, efforts should be made to minimize circuitry changes as soon as possible after rod/cone loss. Advances in retinal anatomy/physiology and genetic technologies should allow refinement of future reparative strategies.

    2004-07-01

    The South Carolina Institute for Energy Studies (SCIES), administratively housed at Clemson University, has participated in the advancement of combustion turbine technology for over a decade. The University Turbine Systems Research Program, previously referred to as the Advanced Gas Turbine Systems Research (AGTSR) program, has been administered by SCIES for the U.S. DOE during the 1992-2003 timeframe. The structure of the program is based on a concept presented to the DOE by Clemson University. Under the supervision of the DOE National Energy Technology Laboratory (NETL), the UTSR consortium brings together the engineering departments at leading U.S. universities and U.S. combustion turbine developers to provide a solid base of knowledge for the future generations of land-based gas turbines. In the UTSR program, an Industrial Review Board (IRB) (Appendix C) of gas turbine companies and related organizations defines needed gas turbine research. SCIES prepares yearly requests for university proposals to address the research needs identified by the IRB organizations. IRB technical representatives evaluate the university proposals and review progress reports from the awarded university projects. To accelerate technology transfer technical workshops are held to provide opportunities for university, industry and government officials to share comments and improve quality and relevancy of the research. To provide educational growth at the Universities, in addition to sponsored research, the UTSR provides faculty and student fellowships. The basis for all activities--research, technology transfer, and education--is the DOE Turbine Program Plan and identification, through UTSR consortium group processes, technology needed to meet Program Goals that can be appropriately researched at Performing Member Universities.

    MACC1 (Metastasis Associated in Colon Cancer 1) is a key driver and prognostic biomarker for cancer progression and metastasis in a large variety of solid tumor types, particularly colorectal cancer (CRC). However, no MACC1 inhibitors have been identified yet. Therefore, we aimed to target MACC1 expression using a luciferase reporter-based high-throughput screening with the ChemBioNet library of more than 30,000 compounds. The small molecules lovastatin and rottlerin emerged as the most potent MACC1 transcriptional inhibitors. They remarkably inhibited MACC1 promoter activity and expression, resulting in reduced cell motility. Lovastatin impaired the binding of the transcription factors c-Jun and Sp1 to the MACC1 promoter, thereby inhibiting MACC1 transcription. Most importantly, in CRC-xenografted mice, lovastatin and rottlerin restricted MACC1 expression and liver metastasis. This is-to the best of our knowledge-the first identification of inhibitors restricting cancer progression and metastasis via the novel target MACC1. This drug repositioning might be of therapeutic value for CRC patients.

    ECRIS'02 was held in Jyvaeskylae Finland at the edge of Lake Jyvaeskylae, which was beautiful location to meet and discuss the state of Electron Cyclotron Resonance ion sources. It was the 15th ECR Ion Source Workshop in a series stretching back to the first workshop held November 6, 1978 in Karlsruhe Germany. Overall, the workshop reports could be characterized as showing solid achievements and steady progress without any spectacular breakthroughs or highly controversial new ideas. In this short report, I will mention some of the highlights and surprises of the workshop that I observed during the meeting and reported on at the close of the meeting. As such, it will be relatively brief and not meant to be all encompassing. A short list of items that made this workshop memorable is given

    Many natural and biomimetic platelet-matrix composites--such as nacre, silk, and clay-polymer-exhibit a remarkable balance of strength, toughness and/or stiffness, which call for a universal measure to quantify this outstanding feature given the structure and material characteristics of the constituents. Analogously, there is an urgent need to quantify the mechanics of emerging electronic and photonic systems such as stacked heterostructures. Here we report the development of a unified framework to construct universal composition-structure-property diagrams that decode the interplay between various geometries and inherent material features in both platelet-matrix composites and stacked heterostructures. We study the effects of elastic and elastic-perfectly plastic matrices, overlap offset ratio and the competing mechanisms of platelet versus matrix failures. Validated by several 3D-printed specimens and a wide range of natural and synthetic materials across scales, the proposed universally valid diagrams have important implications for science-based engineering of numerous platelet-matrix composites and stacked heterostructures.

    In Japan Atomic Energy Agency (JAEA), various systems associated with the collaboration with industries and universities on the Nuclear Fuel Cycle and the Postdoctoral Fellow system, etc. are enacted. These systems have been operated considering the needs of JAEA's program, industry and academia, resultantly contributed, for example, to basic research and the project development. The activities under these collaboration systems contain personal exchanges, the publication of the accomplishments and utilization of those, in research and development concerning geological disposal technology of high-level radioactive waste (HLW). These activities have progressed in Power Reactor and Nuclear Fuel Development Corporation (PNC) and Japan Nuclear Cycle Development Institute (JNC), which are the successive predecessors of JAEA, through JAEA. The accomplishments from these systems have been not only published as papers in journals and individual technical reports but also integrated into the project reports, accordingly contributed to the advancement of the national program on the geological disposal of HLW. In this report, the progress of the research and development under these systems was investigated from the beginning of the operation of the systems. The contribution to the research and development on geological disposal technology of HLW was also studied. On the basis of these studies, the future utilization of the systems of the collaboration was also discussed from the view point of the management of research and development program. A CD-ROM is attached as an appendix. (J.P.N.)

  12. Cosmic microwave background radiation of black hole universe

    2010-11-01

    Modifying slightly the big bang theory, the author has recently developed a new cosmological model called black hole universe. This new cosmological model is consistent with the Mach principle, Einsteinian general theory of relativity, and observations of the universe. The origin, structure, evolution, and expansion of the black hole universe have been presented in the recent sequence of American Astronomical Society (AAS) meetings and published recently in a scientific journal: Progress in Physics. This paper explains the observed 2.725 K cosmic microwave background radiation of the black hole universe, which grew from a star-like black hole with several solar masses through a supermassive black hole with billions of solar masses to the present universe with hundred billion-trillions of solar masses. According to the black hole universe model, the observed cosmic microwave background radiation can be explained as the black body radiation of the black hole universe, which can be considered as an ideal black body. When a hot and dense star-like black hole accretes its ambient materials and merges with other black holes, it expands and cools down. A governing equation that expresses the possible thermal history of the black hole universe is derived from the Planck law of black body radiation and radiation energy conservation. The result obtained by solving the governing equation indicates that the radiation temperature of the present universe can be ˜2.725 K if the universe originated from a hot star-like black hole, and is therefore consistent with the observation of the cosmic microwave background radiation. A smaller or younger black hole universe usually cools down faster. The characteristics of the original star-like or supermassive black hole are not critical to the physical properties of the black hole universe at present, because matter and radiation are mainly from the outside space, i.e., the mother universe.

    2006-01-01

    The 2-parameter family of massive variants of Einsteins gravity (on a Minkowski background) found by Ogievetsky and Polubarinov by excluding lower spins can also be derived using universal coupling. A Dirac-Bergmann constrained dynamics analysis seems not to have been presented for these theories, the Freund-Maheshwari-Schonberg special case, or any other massive gravity beyond the linear level treated by Marzban, Whiting and van Dam. Here the Dirac-Bergmann apparatus is applied to these theories. A few remarks are made on the question of positive energy. Being bimetric, massive gravities have a causality puzzle, but it appears soluble by the introduction and judicious use of gauge freedom

    1995-01-01

    Summarized in this report is the progress achieved during the period from November 1, 1994 to October 31, 1995. The experimental work described in this report is in electromagnetic and heavy-ion nuclear physics. The effort in electromagnetic nuclear physics is in preparation for the research program at the Continuous Electron Beam Accelerator Facility (CEBAF) and is focused on the construction and use of the CEBAF Large Acceptance Spectrometer (CLAS). The heavy-ion experiments were performed at the Argonne National Laboratory ATLAS facility and SUNY, Stony Brook. The physics interests driving these efforts at CEBAF are in the study of the structure, interactions, and nuclear-medium modifications of mesons and baryons. This year, an extension of the experiment to measure the magnetic form factor of the neutron was approved by the CEBAF Program Advisory Committee Nine (PAC9) for beam at 6 GeV. The authors also submitted updates to PAC9 on the experiments to measure inclusive η photoproduction in nuclei and electroproduction of the Λ, Λ*(1520), and f 0 (975). In addition to these experiments, the authors collaborated on a proposal to measure rare radiative decays of the φ meson which was also approved by PAC9. Their contributions to the construction of the CLAS include the development of the drift-chamber gas system, drift-chamber software, and controls software. Major has been leading the effort in the construction of the gas system. In the last year, the Hall B gas shed was constructed and the installation of the gas system components built at the University of Richmond has begun. Over the last six years, the efforts in low-energy heavy-ion physics have decreased due to the change in focus to electromagnetic nuclear physics at CEBAF. Most of the heavy-ion work is completed and there are now new experiments planned. Included in this report are two papers resulting from collaborations on heavy-ion experiments

    1994-07-25

    This Progress Report describes the operation of the Los Alamos Meson Physics Facility (LAMPF) and the research programs carried out there for the years 1992 and 1993. The accelerator operated for over 100 days in 1992, providing beams of H{sup +}, H{sup {minus}}, and polarized H{sup {minus}} for a rich and varied research program in nuclear physics. The accelerator had only fair beam availability in 1992 (for example, the average H{sup +} beam availability was 72%), caused largely by problems in the 201-MHz rf system. A major effort was expended to address these problems before the 1993 run. These efforts were rewarded by good beam availability in 1993 and few problems with the 201-MHz system. LAMPF operated remarkably smoothly during 1993, in the midst of a period of great uncertainty in the future of the facility and the downsizing of MP Division, which led to the loss of a large number of key people to positions elsewhere in the Laboratory. The H{sup +} intensity had to be held to no more than {approximately} 800{mu}A because of a vacuum leak in the A2 target. Nevertheless, the accelerator operated very.reliably and the summer run in 1993 proved to be extremely productive. This report discusses the research conducted on: Nuclear and particle physics; atomic physics; radiation effects; materials science; astrophysics; and theoretical physics.

    1998-01-01

    The recent progress of three-dimensional radiation treatment planning was reviewed. And clinical cases such as lung cancer and breast cancer are introduced. In the University of Occupational and Development Health, the treatment system FOCUS which is made up of CT simulator and linac was used mainly. Three-dimensional treatment planning was carried for about 90% of 330 patients who underwent radiotherapy for one year. The target becomes to be accurate and dose distribution with all CT slices in radiation field can be confirmed by using three-dimensional radiation treatment planning apparatus. High dose irradiation localized to tumor part is possible. Relations between total dose and volume of normal tissue and/or tumor can be estimated numerically and easily by DVH. A prediction of indication and affection became possible by this procedure. In conclusion, generalization of three-dimensional radiation treatment planning will bring progress of more effective radiotherapy with less adverse reaction. (K.H.). 21 refs

    Reprogrammed energy metabolism is an emerging hallmark of cancer. Lactate dehydrogenase A (LDHA), a key enzyme involved in anaerobic glycolysis, is frequently deregulated in human malignancies. However, limited knowledge is known about its roles in the progression of osteosarcoma (OS). In this study, we found that LDHA is commonly upregulated in four OS cell lines compared with the normal osteoblast cells (hFOB1.19). Treatment with FX11, a specific inhibitor of LDHA, significantly reduced LDHA activity, and inhibited cell proliferation and invasive potential in a dose dependent manner. Genetic silencing of LDHA resulted in a decreased lactate level in the culture medium, reduced cell viability and decreased cell invasion ability. Meanwhile, silencing of LDHA also compromised tumorigenesis in vivo. Furthermore, knockdown of LDHA remarkably reduced extracellular acidification rate (ECAR) as well as glucose consumption. In the presence of 2-DG, a glycolysis inhibitor, LDHA-mediated cell proliferation and invasion were completely blocked, indicating the oncogenic activities of LDHA may dependent on Warburg effect. Finally, pharmacological inhibition of c-Myc or HIF1α significantly attenuated LDHA expression. Taken together, upregulated LDHA facilitates tumor progression of OS and might be a potential target for OS treatment. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

  4. Universality in few-body systems with large scattering length

    International Nuclear Information System (INIS)

    Hammer, H.-W.

    2005-01-01

    Effective Field Theory (EFT) provides a powerful framework that exploits a separation of scales in physical systems to perform systematically improvable, model-independent calculations. Particularly interesting are few-body systems with short-range interactions and large two-body scattering length. Such systems display remarkable universal features. In systems with more than two particles, a three-body force with limit cycle behavior is required for consistent renormalization already at leading order. We will review this EFT and some of its applications in the physics of cold atoms and nuclear physics. In particular, we will discuss the possibility of an infrared limit cycle in QCD. Recent extensions of the EFT approach to the four-body system and N-boson droplets in two spatial dimensions will also be addressed

    The tasks of neural computation are remarkably diverse. To function optimally, neuronal networks have been hypothesized to operate near a nonequilibrium critical point. However, experimental evidence for critical dynamics has been inconclusive. Here, we show that the dynamics of cultured cortical networks are critical. We analyze neuronal network data collected at the individual neuron level using the framework of nonequilibrium phase transitions. Among the most striking predictions confirmed is that the mean temporal profiles of avalanches of widely varying durations are quantitatively described by a single universal scaling function. We also show that the data have three additional features predicted by critical phenomena: approximate power law distributions of avalanche sizes and durations, samples in subcritical and supercritical phases, and scaling laws between anomalous exponents.

    1980-11-01

    The concept of time is discussed. If time is defined with physical objects, one is led to the contradiction of eternity with finite duration. It is possible to avoid this contradiction by the introduction of different types of time. The concepts of superspace and ''many-fingered time'' are expressions for the variety of times, and not for the breakdown of the concept of time. With the aid of the distinctions of different well-defined notions of time, knowledge about the time-dependent laws of Nature increases

  9. A word from the DG - Major progress for the LHC

    CERN Multimedia

    2006-01-01

    The return to work after the summer holiday period has been marked by significant progress in the installation of the LHC machine and its detectors. At the beginning of the month, the one thousandth superconducting magnet was positioned in the accelerator tunnel. Passing this symbolic milestone is a testament to the successful efforts of the hundreds of LHC collaborators who are working day and night to install the machine in time, and I would like to take this opportunity to congratulate them. Despite the significant technical and organisational difficulties associated with different types of activities being carried out in parallel in a tunnel where space is limited, the LHC installation teams have achieved remarkable feats. As a result, the delays incurred owing to the problems encountered with the cryogenic distribution line in 2004 have been partly recouped. The cryoline is almost complete, with seven out of eight sectors accepted while installation of the eighth is expected to be completed at the...

    2015-01-01

    Sub-Saharan Africa is a highly diverse geo-political region. Any brief discussion of the progress made over the last 15 years towards the Millennium Development Goals (MDGs) will therefore not do justice to the true complexity of context and events. Our focus will be MDG4—to reduce child mortality by 66% from 1990 levels. We will touch briefly on MDG1, to eradicate extreme poverty and hunger, MDG2, to achieve universal primary education, and MDG5, to improve maternal health, which are inextricably linked with child well-being. We will also draw on an eclectic mix of additional global indicators. Acknowledging the limitations of this approach, we first offer a summary of expected progress and then point to debates on future goals. PMID:25613971

    A research programme has been carried out at the University of Pisa to study the thermo-hydraulic transient in pressure suppression containment systems during a LOCA. In the first series of experimental tests remarkable oscillations of pressure were observed both in dry and in wet-well. In order to describe these dynamic phenomena, a mathematical model has been set up; the main out-lines of this model are briefly described and the comparison between the calculated and experimental results is reported.

  17. The NPT regime: Progress and promises

    Full text: Thesis. The 'NPT regime' has arrived at a fateful crossroads. Though extended indefinitely in 1995, its future is my no means secure. The future 'progress' of this treaty will depend upon whether the 'promises' of its States parties are fully implemented and, eventually, upon the treaty's success in achieving fully universal membership. Challenges The treaty faces many short-term and longer-term challenges: Short term - The first Preparatory Committee meeting for the 2005 Review Conference will meet next year. NNWS will want to see some evidence of progress on nuclear disarmament (Art. VI), along the lines prescribed in the 13 'practical steps' agreed at the last Review Conference. Yet progress has been set back by: uncertainties over the future of the ABM Treaty; the failure of START II and the CTBT to enter into force; the lack of a FISMAT treaty and a treaty establishing a NWFZ in Central Asia; continued qualitative improvements in nuclear weapons; hints that nuclear testing may one day resume; the persistence of doctrines of first-use, pre-emptive use, and use against states that use CBW. Other compliance-related questions will arise over safeguards (e.g. the inability of the IAEA to conduct inspections in the DPRK; signs of a breakdown of the norm of full-scope IAEA safeguards, e.g. in South Asia). There are also concerns over the implementation of non-proliferation commitments (e.g. persisting allegations about nuclear weapon programmes in existing NNWS). The terrorist attacks in New York and Washington, D.C. on 11 September should also serve as a reminder of the new terrorist dangers relating to the possible use of weapons of mass destruction and unorthodox delivery systems. Longer term - Selectivity in the enforcement of NPT norms; unilateralism; IAEA funding uncertainties and shortfalls; difficulties in reaching universal membership (India, Pakistan, and Israel); continuing compliance problems with respect to both non-proliferation and

    , compared to controls. Increased rates of brain atrophy over time were observed throughout the premotor cortex, as well as prefrontal cortex, motor cortex, basal ganglia and midbrain, while white matter tract degeneration spread into the splenium of the corpus callosum and motor cortex white matter. Hypometabolism progressed over time in almost all subjects. These findings demonstrate that some subjects with primary progressive apraxia of speech will rapidly evolve and develop a devastating progressive supranuclear palsy-like syndrome ∼ 5 years after onset, perhaps related to progressive involvement of neocortex, basal ganglia and midbrain. These findings help improve our understanding of primary progressive apraxia of speech and provide some important prognostic guidelines. © The Author (2014).

    The conceptual design of heavy ion fusion drivers has now reached a state, where the overall approach has become fairly clear. One design features an RF linac plus current and beam multiplication rings. The present remarks concern the assignment of multiturn injection, beam storage and bunching to an optimized number of rings and transport lines, as well as some criteria for their designs. The main parameter constraints are discussed, showing how they can be met, although there is little flexibility at the present stage of understanding and technology. A shortened version of this report is scheduled for presentation at the ''INS International Symposium on Heavy Ion Accelerators and Their Application to Inertial Fusion'' Tokyo, January 23-27 1984.

  5. Factors Affecting Career Progress of MBA Students

    Vivien T. Supangco

    2001-06-01

    Full Text Available This paper explored the factors that affect career progress of students in the MBA program of the University of the Philippines.To understand career progression, four measures of career progress were used in this study, namely: number of promotions, number of years in between promotions, total cash compensation, and number of administrative levels from the company president. On the other hand, the factors used to explain career progess included human capital, organizational, interpersonal and demographic variables.The results showed that the different measures of career progress had distinct determinants implying different dynamics. It appeared that measures of career progress that are sensitive to the value employers attach to the individual (Whitely, Dougherty, & Dreher, 1991 such as total compensation, total number of promotion and years per promotion were related with human capital factors such as work experience and number of companies worked for. On the other hand, measures that relate to centrality if the position, in which market forces have less impact, were associated with organizational variables such as organization size and the demographic variable gender.While gender did not explain variation in total compensation, number of promotions and number of uears between promotions, these null results are important for two reasons. First, it implies that the female MBA students were at par with their male counterparts as fas as these measures of career progress are concerned. Second, it challenges the generalizability of the finding of gender segregation at the organizational level-where men receive significantly higher wages that women-which is a common finding among studies done in the United States. The results using the MBA students as sample show that income and promotion parity may indeed be achievable and this brings hope to women in general.However, the statistical significance of gender in explaining career progress as centrality

    Terms such as "expanding Universe", "big bang", and "initial singularity", are nowadays part of our common language. The idea that the Universe we observe today originated from an enormous explosion (big bang) is now well known and widely accepted, at all levels, in modern popular culture. But what happens to the Universe before the big bang? And would it make any sense at all to ask such a question? In fact, recent progress in theoretical physics, and in particular in String Theory, suggests answers to the above questions, providing us with mathematical tools able in principle to reconstruct the history of the Universe even for times before the big bang. In the emerging cosmological scenario the Universe, at the epoch of the big bang, instead of being a "new born baby" was actually a rather "aged" creature in the middle of its possibly infinitely enduring evolution. The aim of this book is to convey this picture in non-technical language accessibile also to non-specialists. The author, himself a leading cosm...

    Full Text Available The aim of this study is to determine the relationship between the sense of organizational silence and the organizational culture the instructors perceived. In this study, the scale for determining organizational culture developed by İpek (1999 and the scale for measuring organizational silence developed by Çakıcı (2007 and adapted by Soycan (2010 are used. No remarkable difference was found in the academic staff's sense of organizational silence degree according to their genders and educational backgrounds. It was seen that the instructors' sense of organizational silence had remarkable differences according to their age group, faculty, sense of administration type in their institutions, frequency of their face-to-face communication with their administrators and their thoughts of speaking clearly with their administrators. It was observed that research assistants had a significantly higher sense of organizational silence than the lecturers in the sense of ‘Lack of Experience'. It was seen that academicians who had 1-5 years of employment period had the highest sense of organizational silence while those who had 21 years or more employment period had the lowest sense of organizational silence in the sense of ‘Lack of Experience' of organizational silence. When the points that participant academicians got from organizational silence and organizational culture scales analyzed in the correlation table, it was found out that there was a remarkable relationship between the academicians' sense of organizational silence and sense of organizational culture. This relationship was a medium-level negative relationship between subdimensions of two scales. A medium-level negative relationship between the organizational silence (total and the organizational culture was also seen. Based on the findings, university administrators were proposed to create a participant culture in their institutions as well as to encourage instructors to speak clearly and

    I will discuss the high pressure research of Drs. J. Dean Barnett, Daniel L. Decker and Howard B. Vanfleet of the department of Physics and Astronomy at Brigham Young University and their many graduate students. I will begin by giving a brief history of the beginning of high pressure research at Brigham Young University when H. Tracy Hall came to the University from General Elecrtric Labs. and then follow the work as it progressed from high pressure x-ray diffraction experiments, melting curve measurements under pressure to pressure effects on tracer diffusion and Mossbauer effect spectra. This will be followed by showing the development of pressure calibration techniques from the Decker equation of state of NaCl to the ruby fluorescence spectroscopy and a short discussion of using a liquid cell for hydrostatic measurements and temperature control for precision high pressure measurements. Then I will conclude with a description of thermoelectric measuremnts, critical phenomena at the magnetic Curie point, and the tricritical point of BaTiO_3.

  11. Valleytronics in merging Dirac cones: All-electric-controlled valley filter, valve, and universal reversible logic gate

    Despite much anticipation of valleytronics as a candidate to replace the aging complementary metal-oxide-semiconductor (CMOS) based information processing, its progress is severely hindered by the lack of practical ways to manipulate valley polarization all electrically in an electrostatic setting. Here, we propose a class of all-electric-controlled valley filter, valve, and logic gate based on the valley-contrasting transport in a merging Dirac cones system. The central mechanism of these devices lies on the pseudospin-assisted quantum tunneling which effectively quenches the transport of one valley when its pseudospin configuration mismatches that of a gate-controlled scattering region. The valley polarization can be abruptly switched into different states and remains stable over semi-infinite gate-voltage windows. Colossal tunneling valley-pseudomagnetoresistance ratio of over 10 000 % can be achieved in a valley-valve setup. We further propose a valleytronic-based logic gate capable of covering all 16 types of two-input Boolean logics. Remarkably, the valley degree of freedom can be harnessed to resurrect logical reversibility in two-input universal Boolean gate. The (2 +1 ) polarization states (two distinct valleys plus a null polarization) reestablish one-to-one input-to-output mapping, a crucial requirement for logical reversibility, and significantly reduce the complexity of reversible circuits. Our results suggest that the synergy of valleytronics and digital logics may provide new paradigms for valleytronic-based information processing and reversible computing.

    Significant accomplishments in fabricating ceramic components for the DOE, NASA, and DOD advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. These programs have also demonstrated that additional research is needed in materials and processing development, design methodology, and data base and life prediction before industry will have a sufficient technology base from which to produce reliable cost-effective ceramic engine components commercially. An assessment of needs was completed, and a 5-year program plan was developed with extensive input from private industry. During the course of the Propulsion System Materials Program, remarkable progress has been made in the development of reliable structural ceramics. However, further work is needed to reduce the cost of ceramics to facilitate their commercial introduction, especially in the highly cost-sensitive automotive market. To this end, the direction of the Propulsion System Materials Program is now shifting toward reducing the cost of ceramics to facilitate commercial introduction of ceramic components for near-term engine applications. In response to extensive input from industry, the plan is to extend the engine types which were previously supported to include near-term (5--10 years) applications in conventional automobile and diesel truck engines. To facilitate the rapid transfer of this technology to US industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities. A systematic approach to reducing the cost of components is envisioned. The work elements are as follows: economic cost modeling, ceramic machining, powder synthesis, alternative forming and densification processes, yield improvement, system design studies, standards development, low-expansion ceramics, and testing and data base development.

  13. Controlling myopia progression in children and adolescents

    Full Text Available Molly J Smith, Jeffrey J WallineThe Ohio State University College of Optometry, Columbus, OH, USAAbstract: Myopia is a common disorder, affecting approximately one-third of the US population and over 90% of the population in some East Asian countries. High amounts of myopia are associated with an increased risk of sight-threatening problems, such as retinal detachment, choroidal degeneration, cataracts, and glaucoma. Slowing the progression of myopia could potentially benefit millions of children in the USA. To date, few strategies used for myopia control have proven to be effective. Treatment options such as undercorrection of myopia, gas permeable contact lenses, and bifocal or multifocal spectacles have all been proven to be ineffective for myopia control, although one recent randomized clinical trial using executive top bifocal spectacles on children with progressive myopia has shown to decrease the progression to nearly half of the control subjects. The most effective methods are the use of orthokeratology contact lenses, soft bifocal contact lenses, and topical pharmaceutical agents such as atropine or pirenzepine. Although none of these modalities are US Food and Drug Administration-approved to slow myopia progression, they have been shown to slow the progression by approximately 50% with few risks. Both orthokeratology and soft bifocal contact lenses have shown to slow myopia progression by slightly less than 50% in most studies. Parents and eye care practitioners should work together to determine which modality may be best suited for a particular child. Topical pharmaceutical agents such as anti-muscarinic eye drops typically lead to light sensitivity and poor near vision. The most effective myopia control is provided by atropine, but is rarely prescribed due to the side effects. Pirenzepine provides myopia control with little light sensitivity and few near-vision problems, but it is not yet commercially available as an eye drop or

    The research reactor of Tokyo City University Atomic Energy Research Laboratory (Musashi Institute of Technology reactor) is zirconium-moderated water-cooled solid homogeneous type (TRIGA-II type), and its maximum heat output is 100 kW. It got into the first critical state in January 1963, and since then, it has mainly contributed to education and training for upgrading nuclear engineers, radioactivation analysis and reactor physics, and medical researches, as the joint usage research facilities across Japan. Then, after a long-term suspension, the university submitted the file in 2004 to the Ministry of Education, Culture, Sports, Science and Technology on the dismantling for the purpose of facility abolishment. Through the procedure of submitting a decommissioning plan, it was approved. Furthermore, in order to perform the function stop of the disposal facilities of liquid waste, application for change authorization for the decommissioning plan was submitted and approved. Regarding the progress of the decommissioning plan, the dismantling and removal of waste facilities for liquid waste and solid waste was carried out in FY2011 without any trouble. This paper explains this progress and future work plans. (A.O.)

    The large helical device is a heliotron device with L = 2 and M = 10 continuous helical coils and three pairs of poloidal coils, and all of coils are superconductive. Since the experiments started in 1998, the development of engineering technologies and the demonstration of large-superconducting-machine operations have greatly contributed to an understanding of physics in currentless plasmas and a verification of the capability of fully steady-state operation. In recent plasma experiments, the steady state and high-beta experiments, which are the most important subjects for the realization of attractive fusion reactors, have progressed remarkably and produced two world-record parameters, i.e. the highest average beta of 4.5% in helical devices and the highest total input energy of 1.6 GJ in all magnetic confinement devices. No degradation has been observed in the coil performance, and stable cryogenic operational schemes at 4.4 K have been established. The physics and engineering results from the LHD experiment directly contribute to the design study for a D-T fusion demo reactor FFHR with a LHD-type heliotron configuration

    Full Text Available Background: Sleep deprivation and drowsiness are very common among university students. The aim of this study was to examine the sleep quality and academic achievement among university students across all medical disciplines in Northwest of Iran. Methods: This study was based on data from a longitudinal study, the "Health and Lifestyle of University Students" (HeLiS. The Pittsburgh Sleep Quality Index (PSQI, a self-administered questionnaire consisting of general information about sleep quality, was completed by students during the first eight weeks of the first semester and academic achievement was assessed via Grade Point Average (GPA in the two semesters following the administration of the PSQI. Results: The mean age of students was 19.16±1.04 and the majority were female (64%. The mean overall score on the PSQI was 6.87±2.25; the majority of students (70% had a global PSQI score greater than 5, indicating they were poor sleepers. Only 28% reported getting over 7 hours of sleep. Female students had higher scores than male students in subjective sleep quality, which was statistically significant (2.15 vs. 1.95 respectively, P = 0.01; however, there was no difference between males and females on other component scores or on the global score. Results of a multiple regression model showed that PSQI score was a predictor of academic achievement (β=-.07, P=0.035, which implies that GPA will be lower among students whose quality of sleep is lower. Conclusion: Based on our sleep quality should be considered and assessed, and sleep hygiene should be promoted among medical university students in order to improve academic achievement.

    Evaluation of data from Loss-of-Fluid Test (LOFT) nonnuclear tests has shown a need for profile measurements at several locations in the LOFT piping. A prototype rake consisting of three Drag-Disc Turbine Transducers (DTT) has been designed and fabricated for installation at one location (FE-BL-1) in the blowdown loop. After successful operation during a LOFT nonnuclear test (L1-4) scheduled for May, 1977, additional rakes will be installed in the primary and blowdown loops. A research program to develop a pitot tube rake for measurement of steady state and transient two-phase flows is in progress at McMaster University, Hamilton, Ontario. A rake of thermocouples and pitot tubes will be developed for installation near the emergency core coolant (ECC) injection points

    Financial capacity is a cognitively-complex activity of daily living that has been shown to decline in a number of neurocognitive disorders. Although it has been well established that cognitive decline is common in multiple sclerosis (MS), little is known about possible financial capacity impairment in people with MS. Thus, the objective of the current study is to investigate financial capacity and its neurocognitive correlates in MS. Data from 22 people with progressive MS and a healthy comparison group composed of 18 adults were analyzed. MS diagnoses were made by a board-certified neurologist with experience in MS. Study participants were administered the Financial Capacity Instrument, a performance-based measure of financial capacity, and neuropsychological battery. Overall financial capacity and most complex financial domains were significantly poorer for people with progressive MS in relation to the healthy comparison group, and a number of cognitive variables were associated with financial capacity declines. Financial capacity is a complex cognitively-mediated functional ability that was impaired in 50% of the current sample of people with progressive MS. These results indicate that people with progressive MS are at greater risk for showing impairment in complex financial tasks and should be clinically monitored for possible deficits in financial capacity. © The Author 2017.

    2007-01-01

    Full Text Available The issue of glass ceiling, invisible barriers that limit the access of women to higher level occupations and positions, continues to be of concern. Prior studies in this topic have been mostly conducted based on two perspectives: systemic and personal. However, neither of these two perspectives have managed to completely explain the glass ceiling phenomena in organizations. This paper focuses on higher education institutions in Australia. Incorporating both of these perspectives, this paper investigates the factors that influence career progression of women academics in Australian universities.

    Full Text Available Since 2014, there have been admission tests in mathematics for applicants to the Estonian University of Life Sciences for Geodesy, Land Management and Real Estate Planning; Civil Engineering; Hydraulic Engineering and Water Pollution Control; Engineering and Technetronics curricula. According to admission criteria, the test must be taken by students who have not passed the specific mathematics course state exam or when the score was less than 20 points. The admission test may also be taken by those who wish to improve their state exam score. In 2016, there were 126 such applicants of whom 63 took the test. In 2015, the numbers were 129 and 89 and in 2014 150 and 47 accordingly. The test was scored on scale of 100. The arithmetic average of the score was 30.6 points in 2016, 29.03 in 2015 and 18.84 in 2014. The test was considered to be passed with 1 point in 2014 and 20 points in 2015 and 2016. We analyzed test results and gave examples of problems which were solved exceptionally well or not at all.

  11. Remarkable identities related to the (quantum) elliptic Calogero-Sutherland model

    Langmann, Edwin

    2006-01-01

    We present remarkable functional identities related to the elliptic Calogero-Sutherland (eCS) system. We derive them from a second quantization of the eCS model within a quantum field theory model of anyons on a circle and at finite temperature. The identities involve two eCS Hamiltonians with arbitrary and, in general, different particle numbers N and M, and a particular function of N+M variables arising as anyon correlation function of N particles and M antiparticles. In addition to identities obtained from anyons with the same statistics parameter λ, we also obtain 'dual' relations involving 'mixed' correlation functions of anyons with two different statistics parameters λ and 1/λ. We also give alternative, elementary proofs of these identities by direct computations

    The Midwest Analytical Team for Research Instrumentation of X-Rays (MATRIX) was organized to formulate a research team to design, construct and utilize a port at NSLS for diffuse scattering. MATRIX, which was formally initiated in September of 1980 upon receipt of funding, consists of active members from Purdue University, Northwestern University, University of Illinois, Iowa State University, Michigan Technological University, University of Missouri, and Argonne National Laboratories. The Executive Committee and all design teams have met three times with two other meetings scheduled for 1981. The first year's design phase is near completion and has concentrated around the diffractometer system, beam line, and computer control system. Some changes which have influenced the design progress are the addition of a full time design person and the inclusion of added expertise in our design teams. These changes have accelerated our progress beyond the state originally estimated. These factors have made it possible to advance some aspects of our design, in particular, the monochromator-mirror design which had been reserved for the second year. The final design phase is expected to be completed in early 1982 with installation in late summer of 1982. Initial research on local atomic arrangements and lattice effects will then be initiated

    generated the cosmological fluctuations observed today. Any detection of significant non-Gaussianity would thus have profound implications for our understanding of cosmic structure formation. The large-scale mass distribution in the Universe is a sensitive probe of the nature of initial conditions. Recent theoretical progress together with rapid developments in observational techniques will enable us to critically confront predictions of inflationary scenarios and set constraints as competitive as those from the Cosmic Microwave Background. In this paper, we review past and current efforts in the search for primordial non-Gaussianity in the large-scale structure of the Universe.

    Compelling epidemiologic evidence indicates that obesity is associated with a high risk of human malignancies, including thyroid cancer. We previously demonstrated that a high fat diet (HFD) effectively induces the obese phenotype in a mouse model of aggressive follicular thyroid cancer (ThrbPV/PVPten+/-mice). We showed that HFD promotes cancer progression through aberrant activation of the leptin-JAK2-STAT3 signaling pathway. HFD-promoted thyroid cancer progression allowed us to test other molecular targets for therapeutic opportunity for obesity-induced thyroid cancer. Metformin is a widely used drug to treat patients with type II diabetes. It has been shown to reduce incidences of neoplastic diseases and cancer mortality in type II diabetes patients. The present study aimed to test whether metformin could be a therapeutic for obesity-activated thyroid cancer. ThrbPV/PVPten+/-mice were fed HFD together with metformin or vehicle-only, as controls, for 20 weeks. While HFD-ThrbPV/PVPten+/-mice had shorter survival than LFD-treated mice, metformin had no effects on the survival of HFD-ThrbPV/PVPten+/-mice. Remarkably, metformin markedly decreased occurrence of capsular invasion and completely blocked vascular invasion and anaplasia in HFD-ThrbPV/PVPten+/-mice without affecting thyroid tumor growth. The impeded cancer progression was due to the inhibitory effect of metformin on STAT3-ERK-vimentin and fibronectin-integrin signaling to decrease tumor cell invasion and de-differentiation. The present studies provide additional molecular evidence to support the link between obesity and thyroid cancer risk. Importantly, our findings suggest that metformin could be used as an adjuvant in combination with antiproliferative modalities to improve the outcome of patients with obesity-activated thyroid cancer.

    We construct a class of two-dimensional (2D) phosphorus allotropes by assembling a previously proposed ultrathin metastable phosphorus nanotube into planar structures in different stacking orientations. Based on first-principles methods, the structures, stabilities, and fundamental electronic properties of these allotropes are systematically investigated. Our results show that these 2D van der Waals phosphorene allotropes possess remarkable stabilities due to the strong intertube van der Waals interactions, which cause an energy release of about 30 - 70 meV /atom , depending on their stacking details. Most of them are confirmed to be energetically more favorable than the experimentally viable α -P and β -P . Three of them, showing a relatively higher probability of being synthesized in the future, are further confirmed to be dynamically stable semiconductors with strain-tunable band gaps and intrinsic piezoelectricity, which may have potential applications in nanosized sensors, piezotronics, and energy harvesting in portable electronic nanodevices.

  2. Entropy in an expanding universe

    1982-01-01

    The question of how the observed evolution of organized structures from initial chaos in the expanding universe can be reconciled with the laws of statistical mechanics is studied, with emphasis on effects of the expansion and gravity. Some major sources of entropy increase are listed. An expanding causal region is defined in which the entropy, though increasing, tends to fall further and further behind its maximum possible value, thus allowing for the development of order. The related questions of whether entropy will continue increasing without limit in the future, and whether such increase in the form of Hawking radiation or radiation from positronium might enable life to maintain itself permanently, are considered. Attempts to find a scheme for preserving life based on solid structures fail because events such as quantum tunneling recurrently disorganize matter on a very long but fixed time scale, whereas all energy sources slow down progressively in an expanding universe. However, there remains hope that other modes of life capable of maintaining themselves permanently can be found

  3. The growth of language: Universal Grammar, experience, and principles of computation.

    Human infants develop language remarkably rapidly and without overt instruction. We argue that the distinctive ontogenesis of child language arises from the interplay of three factors: domain-specific principles of language (Universal Grammar), external experience, and properties of non-linguistic domains of cognition including general learning mechanisms and principles of efficient computation. We review developmental evidence that children make use of hierarchically composed structures ('Merge') from the earliest stages and at all levels of linguistic organization. At the same time, longitudinal trajectories of development show sensitivity to the quantity of specific patterns in the input, which suggests the use of probabilistic processes as well as inductive learning mechanisms that are suitable for the psychological constraints on language acquisition. By considering the place of language in human biology and evolution, we propose an approach that integrates principles from Universal Grammar and constraints from other domains of cognition. We outline some initial results of this approach as well as challenges for future research. Copyright © 2017 Elsevier Ltd. All rights reserved.

  4. Observing golden-mean universality class in the scaling of thermal transport

    Science.gov (United States)

    2018-02-01

    We address the issue of whether the golden-mean [ψ =(√{5 }+1 ) /2 ≃1.618 ] universality class, as predicted by several theoretical models, can be observed in the dynamical scaling of thermal transport. Remarkably, we show strong evidence that ψ appears to be the scaling exponent of heat mode correlation in a purely quartic anharmonic chain. This observation seems to somewhat deviate from the previous expectation and we explain it by the unusual slow decay of the cross correlation between heat and sound modes. Whenever the cubic anharmonicity is included, this cross correlation gradually dies out and another universality class with scaling exponent γ =5 /3 , as commonly predicted by theories, seems recovered. However, this recovery is accompanied by two interesting phase transition processes characterized by a change of symmetry of the potential and a clear variation of the dynamic structure factor, respectively. Due to these transitions, an additional exponent close to γ ≃1.580 emerges. All this evidence suggests that, to gain a full prediction of the scaling of thermal transport, more ingredients should be taken into account.

This image, taken with the NASA/ESA Hubble Space Telescope, reveals startling new details of one of the most unusual nebulae known in our galaxy. Catalogued as HD 44179, this nebula is more commonly called the 'Red Rectangle' because of its unique shape and colour as seen with ground-based telescopes. Hubble has revealed a wealth of new features in the Red Rectangle that cannot be seen by ground-based telescopes looking through Earth’s turbulent atmosphere. Details of the Hubble study were published in the April 2004 issue of The Astronomical Journal. HD 44179 Nebula hi-res Size hi-res: 1289 Kb Credits: ESA and Vincent Icke (Leiden University, the Netherlands) Simulating the Red Rectangle The NASA/ESA Hubble Space Telescope has revealed a wealth of new features in the Red Rectangle that cannot be seen with ground-based telescopes looking through the Earth’s turbulent atmosphere. Whereas the origins of many of the features in this dying star still remain hidden or even outright mysterious, some are well explained by theorists like the Dutch scientist Vincent Icke from Leiden University in the Netherlands. In 1981 Vincent Icke and collaborators showed that a spherical gas ejection from a dying star hitting a dust torus would give rise to shocks that can produce cone-like outflows similar to the two cones seen in the Hubble image. Meteorologists produce weather forecasts by advanced calculations of temperatures, pressures, velocities and densities for the air masses in our atmosphere and, to some degree, theorists like Icke are doing exactly the same for objects in space. Whether modelling the weather in the Earth’s atmosphere or the processes in distant gaseous nebulae, scientists calculate the motion of the gas by using a complicated set of

    Full Text Available In this paper I proposed myself to approach issues related to the intrapreneuriat, which represents a powerful approach of the organizational change. Throughout the paper I tried to provide adequate answers to the requests concerning the intrapreneurial management approach and the concepts derived – intrapreneurial unit, intrapreneur manager, intrapreneurial – strategy – as an important factor of the work improvement on the grounds of efficiency and effectiveness, especially at the University because higher education institutions offer a variety of activities and opportunities for the intrapreneuriat. I also presented the specific features of the university intrapreneurial units and I detailed the intrapreneurial approach in higher education institutions. In the society based on knowledge, the universities as centers of innovation, creativity and critical thinking can successfully implement the intrapreneurial management as a progress and generating new value factor.

    Developing human capital in nuclear with required nuclear background and professional qualifications is necessary to support the implementation of nuclear power projects in the near future. Sufficient educational and training skills are required to ensure that the human resources needed by the nuclear power industry meets its high standard. The Government of Malaysia has made the decision to include nuclear as one of the electricity generation option for the country, post 2020 in order to cater for the increasing energy demands of the country as well as to reduce CO{sub 2} emission. The commitment by the government has been made clearer with the inclusion of the development of first NPP by 2021 in the Economic Transformation Program (ETP) which was launched by the government in October 2010. The In tandem with the government initiative to promote nuclear energy, Center for Nuclear Energy, College of Engineering, Universiti Tenaga Nasional (UNITEN) is taking the responsibility in developing human capital in the area of nuclear power and technology. In the beginning, the College of Engineering has offered the Introduction to Nuclear Technology course as a technical elective course for all undergraduate engineering students. Gradually, other nuclear technical elective courses are offered such as Nuclear Policy, Security and Safeguards, Introduction to Nuclear Engineering, Radiation Detection and Nuclear Instrumentation, Introduction to Reactor Physics, Radiation Safety and Waste Management, and Nuclear Thermal-hydraulics. In addition, another course Advancement in Nuclear Energy is offered as one of the postgraduate elective courses. To enhance the capability of teaching staffs in nuclear areas at UNITEN, several junior lecturers are sent to pursue their postgraduate studies in the Republic of Korea, United States and the United Kingdom, while the others are participating in short courses and workshops in nuclear that are conducted locally and abroad.

    Blood transfusion services face an ever-increasing demand for donor platelets to meet clinical needs. Whilst strategies for increasing platelet storage life and improving the efficiency of donor platelet collection are important, in the longer term, platelets generated by bio-manufacturing processes will be required to meet demands. Production of sufficient numbers of in vitro-derived platelets for transfusion represents a significant bioengineering challenge. In this review, we highlight recent progress in this area of research and outline the main technical and biological obstacles that need to be met before this becomes feasible and economic. A critical consideration is assurance of the functional properties of these cells as compared to their fresh, donor collected, counterparts. We contend that platelet-like particles and in vitro-derived platelets that phenotypically resemble fresh platelets must deliver the same functions as these cells upon transfusion. We also note recent progress with immortalized megakaryocyte progenitor cell lines, molecular strategies for reducing expression of HLA Class I to generate universal donor platelets and the move to early clinical studies with in vitro-derived platelets.

    1978-11-01

    Over the past several years thenumber of radiation overexposures experienced in the radiography industry has been higher than for any other single group of NRC licensees. To inform radiography licensees of NRC's concern fo these recurring overexposure incidents, NRC staff representatives met with licensees in a series of five regional meetings. At these meetings the staff presented prepared remarks and answered questions on NRC regulations and operations. The main purposes of the meetings were to express NRC's concern for the high incidence of overexposures, and to open a line of communication between the NRC and radiography licensees in an effort to achieve the common goal of improved radiation safety. The remarks presented by the staff and subjects discussed at these meetings included: the purpose, scope, findings and goals of the NRC inspection program; ways and means of incorporating safety into radiography operations; and case histories of overexposure incidents, with highlights of the causes and possible preventions. At each of the regional meetings the staff received a request for a copy of the prepared remarks and a consolidation of the questions and answers that were discussed. This document includes that information, and a copy is being provided to each organizaion or firm attending the regional meetings. Requests for other copies should be made in accordance with the directions printed inside the front cover of this document

    Full Text Available Simron Singh,1 Xufang Wang,2 Calvin HL Law1 1Sunnybrook Odette Cancer Center, University of Toronto, Toronto, ON, Canada; 2Novartis Oncology, Florham Park, NJ, USA Abstract: Overall survival can be difficult to determine for slowly progressing malignancies, such as neuroendocrine tumors. We investigated whether time to disease progression is positively associated with overall survival in patients with such tumors. A literature review identified 22 clinical trials in patients with neuroendocrine tumors that reported survival probabilities for both time to disease progression (progression-free survival and time to progression and overall survival. Associations between median time to disease progression and median overall survival and between treatment effects on time to disease progression and treatment effects on overall survival were analyzed using weighted least-squares regression. Median time to disease progression was significantly associated with median overall survival (coefficient 0.595; P=0.022. In the seven randomized studies identified, the risk reduction for time to disease progression was positively associated with the risk reduction for overall survival (coefficient on −ln[HR] 0.151; 95% confidence interval −0.843, 1.145; P=0.713. The significant association between median time to disease progression and median overall survival supports the assertion that time to disease progression is an alternative end point to overall survival in patients with neuroendocrine tumors. An apparent albeit not significant trend correlates treatment effects on time to disease progression and treatment effects on overall survival. Informal surveys of physicians’ perceptions are consistent with these concepts, although additional randomized trials are needed. Keywords: neuroendocrine tumors, progression-free survival, disease progression, mortality

    2015-12-01

    Full Text Available Background. In 2009 a new case-based instructional design was implemented during the preclinical year of study of the undergraduate dental curriculum of the University of Pretoria, South Africa. The objective of the educational intervention was to improve the development of clinical reasoning skills. To achieve this, systematic scaffolding, relevance, integration and problem-solving were actively promoted as part of teaching and learning. A student’s clinical reasoning was measured by a progress test containing 32 multiple choice questions (MCQs, formulated on a knowledge application level. In 2011 it became clear that some students showed progression while others did not. Objectives. This study was conducted to gauge the value of the case-based intervention with the aim of determining the need for further scaffolding and support, especially for non-progressing students. Methods. The 2011 BChD IV cohort (N=48 was identified for the study. Two semi-structured focus group discussions were conducted. Group 1 (n=8 consisted of students who progressed ≥9%, while group 2 (n=8 comprised students who did not progress to the same extent. Results. Both groups lauded the scaffolding that the case-based curriculum provided. Strategic thinking, goal orientation and self-regulation ability were identified in group 1. A lack of diligence, poor data-processing ability and a possible lack of interest were identified in group 2 students, who were unaware of learning opportunities. Conclusion. There is a need for early identification of students lacking self-regulated learning and for providing timely feedback and support to progressively develop their clinical reasoning skills.

    The main purpose of this book is to present, in a comprehensive and progressive way, the appearance of universal limit probability laws in physics, and their connection with the recently developed scaling theory of fluctuations. Arising from the probability theory and renormalization group methods, this novel approach has been proved recently to provide efficient investigative tools for the collective features that occur in any finite system. The mathematical background is self-contained and is formulated in terms which are easy to apply to the physical context. After illustrating the problem

  6. Remark on state vector construction when flavor mixing exists

    International Nuclear Information System (INIS)

    Fujii, K.; Shimomura, T.

    2006-01-01

    In the framework of quantum field theory, we consider the way to construct the one-particle state (with definite 3-momentum) when particle mixing exists, such as in the case of flavor-neutrino mixing. In the preceding report (Prog. Theor. Phys. 112, 901 (2004)), we have examined the structure of expectation values of the flavor neutrino charges (at time t) with respect to a neutrino-source state prepared at time t' (earlier than t). When there is no mixing, each of various contributions to the expectation value is equal, in its dominant part, to the transition probability corresponding to the respective neutrino-production process. On the basis of the assumption that such an equality holds also in the mixing case, we can find an appropriate form of one-flavor-neutrino state with 3-momentum and helicity. Along the same way, we examine the boson case when flavor mixing exists. We give remarks on the relation and difference between the ordinary and the present approaches to flavor oscillation

    The Graphical user interface has traditionally supported personal productivity, efficiency, and usability. With computer supported cooperative work, the focus has been on typical people, doing typical work in a highly rational model of interaction. Recent trends towards mobility, and emotional and universal design are extending the user interface paradigm beyond the routine. As computing moves into the hand and away from the desktop, there is a greater need for dealing with emotions and distractions. Busy and distracted people represent a new kind of disability, but one that will be increasingly prevalent. In this panel we examine the current state of the art, and prospects for future collaboration in non-normative computing requirements. This panel draws together researchers who are studying the problems of mobility, emotion and universality. The goal of the panel is to discuss how progress in these areas will change the nature of future collaboration.

  12. The remarkably high excitation planetary nebula GC 6537.

    1999-05-11

    NGC 6537 is an unusually high excitation point symmetric planetary nebula with a rich spectrum. Its kinematical structures are of special interest. We are here primarily concerned with the high resolution spectrum as revealed by the Hamilton echelle Spectrograph at Lick Observatory (resolution approximately 0.2 A) and supplemented by UV and near-UV data. These extensive data permit a determination of interstellar extinction, plasma diagnostics, and ionic concentrations. The photoionization models that have been used successfully for many planetary nebulae are not entirely satisfactory here. The plasma electron temperature of a photoionization model cannot much exceed 20,000 K, but plasma diagnostics show that regions emitting radiation of highly ionized atoms such as [NeIV] and [NeV] are much hotter, showing that shock excitation must be important, as suggested by the remarkable kinematics of this object. Hence, instead of employing a strict photoionization model, we are guided by the nebular diagnostics, which reveal how electron temperature varies with ionization potential and accommodates density effects. The predictions of the photoionization model may be useful in estimating ionization correction factor. In effect, we have estimated the chemical composition by using both photoionization and shock considerations.

  13. T2 map signal variation predicts symptomatic osteoarthritis progression: data from the Osteoarthritis Initiative

    2016-07-15

    The aim of this work is to use quantitative magnetic resonance imaging (MRI) to identify patients at risk for symptomatic osteoarthritis (OA) progression. We hypothesized that classification of signal variation on T2 maps might predict symptomatic OA progression. Patients were selected from the Osteoarthritis Initiative (OAI), a prospective cohort. Two groups were identified: a symptomatic OA progression group and a control group. At baseline, both groups were asymptomatic (Western Ontario and McMaster Universities Arthritis [WOMAC] pain score total <10) with no radiographic evidence of OA (Kellgren-Lawrence [KL] score ≤ 1). The OA progression group (n = 103) had a change in total WOMAC score greater than 10 by the 3-year follow-up. The control group (n = 79) remained asymptomatic, with a change in total WOMAC score less than 10 at the 3-year follow-up. A classifier was designed to predict OA progression in an independent population based on T2 map cartilage signal variation. The classifier was designed using a nearest neighbor classification based on a Gaussian Mixture Model log-likelihood fit of T2 map cartilage voxel intensities. The use of T2 map signal variation to predict symptomatic OA progression in asymptomatic individuals achieved a specificity of 89.3 %, a sensitivity of 77.2 %, and an overall accuracy rate of 84.2 %. T2 map signal variation can predict symptomatic knee OA progression in asymptomatic individuals, serving as a possible early OA imaging biomarker. (orig.)

    To review the application and research progress of subtalar distraction bone block arth-rodesis in the treatment of calcaneus fracture malunion. The recent literature concerning the history, surgical technique, postoperative complication, indications, and curative effect of subtalar distraction arthrodesis with bone graft block interposition in the treatment of calcaneus fracture malunion was summarized and analyzed. Subtalar distraction bone block arthrodesis is one of the main ways to treat calcaneus fracture malunion, including a combined surgery with subtalar arthrodesis and realignment surgery for hindfoot deformity using bone block graft. The advantage is on the base of subtalar joint fusion, through one-time retracting subtalar joint, the posterior articular surface of subtalar joint implants bone block can partially restore calcaneal height, thus improving the function of the foot. Compared with other calcaneal malunion treatments, subtalar distraction arthrodesis is effective to correct complications caused by calcaneus fracture malunion, and it can restore the height of talus and calcaneus, correct loss of talocalcaneal angle, and ease pain. Subtalar distraction bone block arthrodesis has made remarkable progress in the treatment of calcaneus fracture malunion, but it has the disadvantages of postoperative nonunion and absorption of bone block, so further study is needed.

    2012-01-01

    A 55-year-old female presented at Department of Pañcakarma with diagnosis of progressive supranuclear palsy (PSP). For assessing disability, progressive supranuclear palsy rating scale (PSPRS) was used and balance was assessed by using Tetrax Interactive Balance System (IBS) posturography. Āyurvedic treatment was given along with Pañcakarma and balance exercises for 3 months. As part of Āyurvedic treatment, first Virecana karma was done with classical method and then Mātrā basti, Śirobasti, and other palliative treatment was given for 3 months. Amanatidine was not continued during Virecana karma but started thereafter. On comparison with pre-intervention scores, there was a significant improvement in the patient post-treatment. The features which mainly showed improvement were: Eye movements, spontaneous episodes of laughing, dysphagia, dysarthria, double vision, and neck rigidity. Balance showed significant improvement and there was a remarkable decrease in the postural sway. This case study may present new possibilities for treatment of neurodegenerative diseases by Āyurveda.

  18. Some remarks on the attractor behaviour in ELKO cosmology

    Pereira, S. H.; A. Pinho S., S.; Hoff da Silva, J. M.

    2014-08-01

    Recent results on the dynamical stability of a system involving the interaction of the ELKO spinor field with standard matter in the universe have been reanalysed, and the conclusion is that such system does not exhibit isolated stable points that could alleviate the cosmic coincidence problem. When a constant parameter δ related to the potential of the ELKO field is introduced in the system however, stable fixed points are found for some specific types of interaction between the ELKO field and matter. Although the parameter δ is related to an unknown potential, in order to satisfy the stability conditions and also that the fixed points are real, the range of the constant parameter δ can be constrained for the present time and the coincidence problem can be alleviated for some specific interactions. Such restriction on the ELKO potential opens possibility to apply the ELKO field as a candidate to dark energy in the universe, and so explain the present phase of acceleration of the universe through the decay of the ELKO field into matter.

    Sablik, Zbigniew; Samborska-Sablik, Anna; Drożdż, Jarosław

    2013-06-20

    The aim of our work is to present the universality of burnout syndrome among physicians worldwide and to demonstrate selected aspects of the relationship between patients and doctors as a common factor predisposing to burnout. We looked up 20 original pieces of research from the Medline database published in the last 10 years to determine the prevalence of burnout among doctors in different countries. In all quoted works a remarkable percentage of doctors of interventional and non-interventional specialties suffered burnout. Because it is the relationship with patients that constitutes a key denominator for their work, in the discussion we have exposed an important aspect of it, destructive patient games, described on the basis of transactional analysis. Since universal burnout causes a deterioration of doctors' service, for the optimal good of the patient to survive preservation of the doctor's well-being in the patient-doctor relationship is needed everywhere.

  20. Universal features of JIMWLK and BK evolution at small x

    CERN Document Server

    Rummukainen, K; Rummukainen, Kari; Weigert, Heribert

    2004-01-01

    In this paper we present the results of numerical studies of the JIMWLK and BK equations with a particular emphasis on the universal scaling properties and phase space structure involved. The results are valid for near zero impact parameter in DIS. We demonstrate IR safety due to the occurrence of a rapidity dependent saturation scale Q_s(\\tau). Within the set of initial conditions chosen both JIMWLK and BK equations show remarkable agreement. We point out the crucial importance of running coupling corrections to obtain consistency in the UV. Despite the scale breaking induced by the running coupling we find that evolution drives correlators towards an asymptotic form with near scaling properties. We discuss asymptotic features of the evolution, such as the \\tau- and A-dependence of Q_s away from the initial condition.
