  14. Paths discovered: Canguilhem and the Annales scholl

    Directory of Open Access Journals (Sweden)

    Francisco Vázquez García

    2016-05-01

    Full Text Available In this paper we analyze the reception of the Annales school in the work of Georges Canguilhem. Usually scholars tend to emphasize the parallel and at the same time, the mutual ignorance among historians of the Annales group and representatives of the French historical epistemology (Cavaillès , Koyré , Bachelard , Canguilhem. The latter, however, is an exception, because he was very familiar with the work of what he called "team of Strasbourg" (Febvre, Bloch, Halbwachs. Using abundant unpublished sources, we try to prove that this meeting decisively affected the historical epistemology practiced by Canguilhem.

  15. One hundred and twenty-five years of the Annals of Botany. Part 2: the years 1937 to 2012.

    Science.gov (United States)

    Jackson, Michael B

    2016-12-01

    Annals of Botany is a peer-reviewed plant biology journal. It was started in 1887, making it the oldest continuously published plant science title. A previous article [Jackson MB. 2015. One hundred and twenty-five years of the Annals of Botany Part 1: the first 50 years (1887-1936). Annals of Botany 115: : 1-18] summarized events leading to its founding, highlighted the individuals involved and examined the Journal's achievements and management practices over the first 50 years to 1937. This second article covers the next 75 years. The account draws principally on the Journal's own records, minute books, financial accounts, original letters and notes held by the Annals of Botany Company, the Journal's owners and managers. In 1937, its 51st year, the Journal was re-launched as Annals of Botany New Series and its volume numbers were reset to No. I. The present article evaluates the evolution of the New Series up to 2012, Annals of Botany's 125th anniversary year. The period includes a 2-year run-up to World War II, six war years and their immediate aftermath, and then on through increasingly competitive times. The ebb and flow of the Journal's fortunes are set against a roll-call of the often highly distinguished scientists who managed and edited the Journal. The article also examines an internal crisis in the 1980s that radically altered the Journal's organization in ways that were, ultimately, to its benefit. The narrative is set against changes to economic conditions in Great Britain over the period, to the evolving nature and geographical distribution of much experimental plant science and to the digital revolution that, from the late 20th century, transformed the workings of Annals of Botany and of scientific publishing more generally. © The Author 2016.

  3. TRANSFORMATION

    Energy Technology Data Exchange (ETDEWEB)

    LACKS,S.A.

    2003-10-09

    Transformation, which alters the genetic makeup of an individual, is a concept that intrigues the human imagination. In Streptococcus pneumoniae such transformation was first demonstrated. Perhaps our fascination with genetics derived from our ancestors observing their own progeny, with its retention and assortment of parental traits, but such interest must have been accelerated after the dawn of agriculture. It was in pea plants that Gregor Mendel in the late 1800s examined inherited traits and found them to be determined by physical elements, or genes, passed from parents to progeny. In our day, the material basis of these genetic determinants was revealed to be DNA by the lowly bacteria, in particular, the pneumococcus. For this species, transformation by free DNA is a sexual process that enables cells to sport new combinations of genes and traits. Genetic transformation of the type found in S. pneumoniae occurs naturally in many species of bacteria (70), but, initially only a few other transformable species were found, namely, Haemophilus influenzae, Neisseria meningitides, Neisseria gonorrheae, and Bacillus subtilis (96). Natural transformation, which requires a set of genes evolved for the purpose, contrasts with artificial transformation, which is accomplished by shocking cells either electrically, as in electroporation, or by ionic and temperature shifts. Although such artificial treatments can introduce very small amounts of DNA into virtually any type of cell, the amounts introduced by natural transformation are a million-fold greater, and S. pneumoniae can take up as much as 10% of its cellular DNA content (40).

    Transformers of a type adapted for use with extreme high power vacuum tubes where current requirements may be of the order of 2,000 to 200,000 amperes are described. The transformer casing has the form of a re-entrant section being extended through an opening in one end of the cylinder to form a coaxial terminal arrangement. A toroidal multi-turn primary winding is disposed within the casing in coaxial relationship therein. In a second embodiment, means are provided for forming the casing as a multi-turn secondary. The transformer is characterized by minimized resistance heating, minimized external magnetic flux, and an economical construction.

  15. Developing new drugs from annals of Chinese medicine

    Directory of Open Access Journals (Sweden)

    Zhaoxiang Bian

    2012-02-01

    Full Text Available Developing new pharmaceuticals requires massive amounts of time, money and efforts. The key step is how to find a safe and effective entity for a disease condition and how to develop it as new drug effectively. Unfortunately, the FDA's rate of approving new entities has declined dramatically in the last three decades. There is a strong need to review the current strategy and to optimize process in developing new drugs, both to shorten the process and increase the success rate. Chinese medicine has used natural products to treat patients for thousands of years, and Chinese medicine practitioners have chronicled the patients and treatment methods for thousands of years. There is much information that has not yet been used. The success stories of artimisinin and arsentic trioxide are wonderful examples of how the annals of Chinese medicine can provide leads for discovering new drugs. This paper argues that the annals of Chinese medicine are valuable and describes how they can be used in modern drug discovery. The major topics addressed are: (i why Chinese medicine is a rich resource for finding new drugs; (ii how to identify a potential valuable record from Chinese medicine annals; (iii when a potential valuable record is identified from annals, how to proceed; and (iv both why and how the approach used for chemical drugs should be revised for drugs based on the historical documents related to herbal medicine. In conclusion, we argue here that the annals of Chinese medicine offer not only a rich resource for new drugs, but also several centuries of patient data with regard to safety and efficacy, that in effect represent pilot studies. Acknowledging and using these data can shorten new drug discovery time and improve efficiency of the drug development process, bringing more effective, safe drugs to market much more quickly and cheaply.

    Annals of the International Geophysical Year, Volume 33: Results of Ionospheric Drift Observations describes the systematic changes in individual ionospheric observations during the International Geophysical Year (IGY). This book is composed of four chapters, and begins with a presentation of the general data on stations and the lists of publications concerning drift work during IGY/IGC. The next chapter contains the results obtained mainly by intercomparison of the time shift between fadings observed on three antenna separated by a distance of roughly a wavelength. These data are followed by

    Pu, Lee; Lineaweaver, William

    2012-06-01

    We reviewed the contributor demographics of recent volumes of Annals of Plastic Surgery to quantify the contributions of authors from countries where the primary language is not English. For 2 volumes of Annals (63 and 65), such authors contributed 57% of the total articles published. Within the new section format of volume 66, authors from non-English language countries accounted for 60% of all original articles with substantial and often dominant representation in all sections. This survey shows that Annals publishes articles from an international population of contributors with effective inclusion of authors from countries with primary languages other than English.

The papers published in the Annales de Réadaptation et Médecine Physique in 2008 were reviewed, classified by topics and discussed. Sixty-four papers are described, with a coverage of all the fields of PRM, from childhood to elderly, from basic science to clinical research, from case studies to epidemiological works. The aim of this paper was to provide physiatrists with some articles of the Annales de Réadaptation et Médecine Physique related to their working condition. Next year, the name of our journal will become Annals of Physical and Rehabilitation Medicine, as most of the articles will be published in French and in English, with the hope that more and more European authors and readers will find it more convenient.

  5. Accessibility of Internet references in Annals of Emergency Medicine: is it time to require archiving?

    Science.gov (United States)

    Thorp, Andrea W; Brown, Lance

    2007-08-01

    We seek to evaluate the accessibility of all Internet references appearing in Annals of Emergency Medicine from 2000, 2003, and 2005. Secondary objectives are to determine whether the number of Internet references is increasing and to describe how Internet references are inaccessible. We visually scanned all articles for references made in the printed version of Annals of Emergency Medicine for 2000, 2003, and 2005. We identified the Internet references and grouped them into 11 categories according to the results of entering the uniform resource locator (URL) into the Internet browser. We identified 15,745 references published in Annals of Emergency Medicine. The proportion of Internet references increased from 1% of the total references in 2000 to 5.4% in 2005. Internet references were not readily accessible for 40 of 51 Internet references in 2000 (78%; 95% confidence interval [CI] 65% to 88%), 161 of 286 Internet references in 2003 (56%; 95% CI 50% to 62%), and 111 of 249 Internet references in 2005 (45%; 95% CI 39% to 51%). Inaccessibility was most commonly manifested by URLs that no longer link to active Web sites (172 of 312 inaccessible Internet references [55%]; 95% CI 50% to 61%) and URLs that linked to generic home pages where the authors' referenced material could not be found (115 of 312 inaccessible Internet references [37%]; 95% CI 32% to 42%). In Annals of Emergency Medicine, older Internet references appear to be less accessible than newer references. Internet reference archiving is one solution to preserving this information for future readers.

  7. [The story of Annales pharmaceutiques françaises. 1809-2009].

    Science.gov (United States)

    Chast, F

    2009-11-01

    The Annales pharmaceutiques françaises is 200 years old. Initially, in 1809, the Bulletin de pharmacie was the organ of the Société de pharmacie de Paris. The journal was one of the dynamic events stimulated by the law of Germinal in year XI of the French revolution (1803). Its readership increased tremendously, rapidly making it the first regular journal in the pharmaceutical world. In 1984 it became the Journal de pharmacie et chimie published for a century. It was in 1943 that the journal took on its current name of the Annales pharmaceutiques françaises. The journal is now the official organ of the French National Academy of Pharmacy. The six annual issues are supplemented by an internet diffusion allowing readers access in all French-speaking countries.

    Directory of Open Access Journals (Sweden)

    Tomas Veteikis

    2008-01-01

    Full Text Available Annales of Ennius, partly aimed at survey of Roman history year by year, partly at memorizing Roman heroes and equating them to gods, though had a few antecedant models in Hellenistic epic, remains unrivalled in respect of vastitude and bravery of the innovatory devise. The poem, praising deeds of Roman god-like ancestors, kings, consuls and tribunes, had certain political aspirations tending to melt the scepticism towards Greek culture and its reception among conservative members of aristocracy of Ennius’ time. On the other hand, being performed in traditional Roman convivial setting, Annales were in accord with Roman piety and reverent attitude towards gods, whence poet’s aim at his own otherness and impartiality might be discerned.Annales of Ennius not only reminds its readers of Roman strategy of gaining over Carthaginian or Greek deities during Roman expansion outside Appenines, but also claims their common identity with Roman gods, whence the idea of Greek and Roman cultural affinity and common genealogy comes. This idea most probably originates from the deep consideration of homeric and hellenistic epic and their exegetical traditions combined with other philosophical views (even contrasting ones attainable in III B. C. Italy. However, the state of extant text of Annales, consisting of over 600 fragmentary verses (plus around 100 more or less identified testimonia together with recently deciphered fragments from Herculanean papyrus, doesn’t provide us with certain argument what attitude in Ennius’ notion prevailed, unless we investigate one by one all the mentions of gods in this poem. The complex task is treated in this article in a selective manner: the main attention is paid only to the limited part of over 40 deities present in Annales, namely, to the Greco-Roman dodekatheon or di consentes, most clearly attested in Ann. 240–241 Sk. The method of investigation rests on the description of each deity separately, both trying to

    Tanner, J M

    1999-01-01

    The history of the founding in 1958 of the Society for the Study of Human Biology is outlined, and the circumstances in which the Annals of Human Biology began publication in 1974. The contents of the papers published 1974-1997 are reviewed; about 40% concern Population Biology, 40% Auxology and 20% Population Physiology. Some outstanding contributions in the first two of these fields are mentioned. Many consist of groups of papers from an ongoing study: 11 papers from the Otmoor villages study by Harrison and colleagues, and 11 concerning the growth of children in the Zurich Longitudinal Study, by Gasser and colleagues. Papers concerning the analysis of growth data and modelling of the growth curve, especially by Healy, are noted, and papers giving evidence of mini-spurts in growth and the saltation-stasis growth model are recalled. Wilson's papers on catch-up and growth regulation in twins are reviewed; also the contribution to growth-as-a-mirror of social conditions by workers at the Stockholm Institute of Education. The National Study of Health and Growth, led by Rona, contributed 13 papers over 14 years to the Annals, and there were outstanding one-off papers from the National Child Development Study, and the Cuban National Growth Study of 1972, and concerning the secular trend towards greater leg length in Japan, the upward social mobility of the taller of pairs of brothers, the growth of 18th century children in Vienna and Stuttgart and the measurements of 19th century slaves in the USA.

  13. The Annals of Braila - The Most Important Regional Culture Journal in the Interwar Period of the Lower Danube

    Directory of Open Access Journals (Sweden)

    Cristina Dosuleanu

    2011-12-01

    Full Text Available “The Annals of Braila” is one of the most important regional cultural journals published in the interwar period, due to the cultural phenomenon of regionalism. This was the response of Romanian intellectuals to the exaggerated influence of the West in all areas, that is the emergence of what Titu Maiorescu called forms without substance. As a result, immediately after the Great Union of 1918, young people, mostly students, who already exposed their ideas in scientific societies, began to organize information-gathering activities in all domains in certain areas and then they published them as scientific texts. That is how regional culture journals appeared in Craiova, Brasov, Timisoara and Constanta. Curiously, all have been mentioned in history books of press or in dictionaries except “The Annals of Braila”. A careful examination shows that the journal was probably not only a refuge, as the Braila journal was as important as the other. And in order to support this we should mention: it appeared for 12 years despite the financial difficulties, while others were released for a smaller period of time, it had as collaborators important people of the Romanian culture and literature, and its studies concerned the entire area of the Lower Danube, the analyzes, documents, information having considered other cities that are on the Danube shores. Therefore, we believe that the “Annals of Braila” journal must stand alongside the other regional culture journals and enjoy the same importance.

  14. The rapid internationalization of Annals of Pediatric Endocrinology & Metabolism as evidenced by journal metrics.

    Science.gov (United States)

    Huh, Sun

    2017-06-01

    Using journal metrics, this paper explores whether Annals of Pediatric Endocrinology & Metabolism has internationalized 4 years after changing its language to English only. From the journal's website and the Web of Science Core Collection, the following metrics were counted or calculated: Number of citable articles, countries of authors and editorial board members, total citations, impact factor, countries of citing authors, citing journal titles, and Hirsch index. From 2012 to 2017, 208 articles were citable. The authors had affiliations in 7 countries and the editorial board members in 14 countries. From 2014 to 2017, the total citations each year were 8, 81, 141, and 61; and the impact factors from 2014 to 2016 were calculated as 0.05, 0.987, and 1.165. The citing authors were from 60 countries, among which the United States, China, South Korea, Italy, and Germany were most common. The journal was cited by 215 journal titles. The Hirsch index was 7. These journal metrics showed that the journal achieved international status 4 years after changing the journals' language into English only. The journal's language policy successfully enabled the journal to rebrand as an international journal.

  15. Physicians as leaders in improving health care: a new series in Annals of Internal Medicine.

    Science.gov (United States)

    Berwick, D M; Nolan, T W

    1998-02-15

    Searching for one word to describe the state of mind of the physician in the United States today, we might choose beleaguered. Threats appear from all sides--from payers, would-be managers of care, the growth of technology, and even patients. The rhetoric is one of siege and battle, and the dynamic seems to be a clash of values from which only one winner can emerge. But scientific and health services research suggest otherwise. Science suggests that health care could, indeed, perform a great deal better than it does today and that a shared aim of improving health outcomes for patients at a cost that society can afford is sensible and within reach. However, achievement of these improvements will require of physicians not handwringing and resistance to change but concerted, positive, capable leadership. The goal of this series in Annals is to describe a new knowledge base that will help physicians participate effectively in the redesign of the health care system. The series is intended to raise the curiosity of physicians about the skills they will need to become more active and influential citizens of the health care community in accomplishing improvements. These skills will help physicians better deploy their clinical expertise and professional purpose in a debate that has heretofore been informed primarily by economics.

    The Associazione Medici Diabetologi-annals initiative is a physician-led quality-of-care improvement scheme that has been shown to improve HbA1c concentration, blood pressure, lipid profiles and BMI in enrolled people with Type 2 diabetes. The present analysis investigated the long-term cost-effectiveness of enrolling people with Type 2 diabetes in the Associazione Medici Diabetologi-annals initiative compared with conventional management. Long-term projections of clinical outcomes and direct costs (in 2010 Euros) were made using a published and validated model of Type 2 diabetes in people with Type 2 diabetes who were either enrolled in the Associazione Medici Diabetologi-annals initiative or who were receiving conventional management. Treatment effects were based on mean changes from baseline seen at 5 years after enrolment in the scheme. Costs and clinical outcomes were discounted at 3% per annum. The Associazione Medici Diabetologi-annals initiative was associated with improvements in mean discounted life expectancy and quality-adjusted life expectancy of 0.55 years (95% CI 0.54-0.57) years and 0.48 quality-adjusted life years (95% CI 0.46-0.49), respectively, compared with conventional management. Whilst treatment costs were higher in the Associazione Medici Diabetologi-annals arm, this was offset by savings as a result of the reduced incidence and treatment of diabetes-related complications. The Associazione Medici Diabetologi-annals initiative was found to be cost-saving over patient lifetimes compared with conventional management [€ 37,289 (95% CI 37,205-37,372) vs € 41,075 (95% CI 40,956-41,155)]. Long-term projections indicate that the physician-led Associazione Medici Diabetologi-annals initiative represents a cost-saving method of improving long-term clinical outcomes compared with conventional management of people with Type 2 diabetes in Italy. © 2013 The Authors.

    The Annals of Botany is a peer-reviewed scientific journal publishing papers on a wide range of topics in plant biology. It first appeared in 1887, making it the oldest continuously published botanical title. The present article gives a historical account of events leading to the founding of the Journal and of its development over the first 50 years. Much of the content is drawn from the Journal's own records and from extensive Minutes, financial accounts, personal letters and notes relating to the Annals of Botany that were repatriated from University College, University of London in 1999. Documents held at the Royal Botanic Gardens, Kew and at the Oxford University Press Museum were also consulted. Emphasis is placed on the individuals who instigated, edited and managed the Annals of Botany up to 1937, especially the nine founding members of the Journal and the background that brought them together and motivated them to start the Annals of Botany. A falling out between two of the founders in 1899 is highlighted since not only did this threaten the Journal's future but also gives much insight into the personalities of those most closely involved in the Journal during its formative years. The article also examines the way the Journal was funded and how it dealt with its publisher (the University of Oxford's Clarendon Press), turned itself into a registered company (the Annals of Botany Company) and coped with the travails of the First World War, currency inflation and the Great Depression. Plans to re-start the Journal as a New Series, beginning in 1937, are discussed in the context of the competition the Annals of Botany then faced from younger journals. © The Author 2014.

  19. The Effect of Peer Review on the Quality of Data Graphs in Annals of Emergency Medicine.

    Schriger, David L; Raffetto, Brian; Drolen, Claire; Cooper, Richelle J

    2017-04-01

    We determine how peer review affects the quality of published data graphs and how the appointment of a graphics editor affects the quality of graphs in an academic medical journal. We conducted an observational time-series analysis to quantify the qualities of data graphs in original manuscripts and published research articles in Annals of Emergency Medicine from 2006 to 2012. We retrospectively analyzed 3 distinct periods: before the use of a graphics editor, graph review after a manuscript's acceptance, and graph review just before the first request for revision. Raters blinded to study year scored the quality of original and published graphs using an 85-item instrument. Editorial comments about graphs were classified into 4 major and 16 minor categories. We studied 60 published articles and their corresponding original submissions during each period (2006, 2009, and 2012). The number of graphs increased 31%, their median data density increased 50%, and quality (completeness [+42%], visual clarity [+64%], and special features [+66%]) increased from submission to publication in all 3 periods. Although geometric mean (0.69, 0.86, and 1.2 pieces of information/cm(2)) and median data density (0.44, 0.70, and 1.2 pieces of information/cm(2)) were higher in the graphics editor phases, mean data density, completeness, visual clarity, and other markers of quality did not improve or decreased with dedicated graphics editing. The majority of published graphs were bar or pie graphs (49%, 53%, and 60% in 2006, 2009, and 2012, respectively) with low data density in all 3 years. Peer review unquestionably improved graph quality. However, data densities of most graphs barely exceeded that of printed text, and many graphs failed to present the majority of available data and did not convey those data clearly; there remains much room for improvement. The timing of graphics editor involvement appears to affect the effect of the graph review process. Copyright © 2016 American

  20. Appell Transformation and Canonical Transforms

    Directory of Open Access Journals (Sweden)

    Amalia Torre

    2011-07-01

    Full Text Available The interpretation of the optical Appell transformation, as previously elaborated in relation to the free-space paraxial propagation under both a rectangular and a circular cylindrical symmetry, is reviewed. Then, the caloric Appell transformation, well known in the theory of heat equation, is shown to be amenable for a similar interpretation involving the Laplace transform rather than the Fourier transform, when dealing with the 1D heat equation. Accordingly, when considering the radial heat equation, suitably defined Hankel-type transforms come to be involved in the inherent Appell transformation. The analysis is aimed at outlining the link between the Appell transformation and the canonical transforms.

    1999-06-01

    To evaluate the quality and evolution of the medical writing of the scientific reports published by the Annales d'Otolaryngologie et de Chirurgie Cervico-faciale. A comparative study of quantitative and qualitative data regarding the medical writting of 98 scientific reports published in 1977, 1987, and 1997 in the Annales d'Otolaryngologie et de Chirurgie Cervico-faciale. Various significant statistical results documented an increase within the quality of the medical writing of the scientific reports published. However, various probllems regarding the medical writing of the chapters "Title", "Summary", or "Discussion", the type of study performed, the use of biostatistics, the references, and the style still exist. Based upon the data collected, the author supports the actual policy of the editorial board regarding the increased severity concerning the medical writing of the scientific reports submitted to the Annales d'Otolaryngologie et de Chirurgie Cervico-faciale. Various propositions are also performed to increase the quality of the medical writting and the diffusion of the scientific reports published by the Annales d'Otolaryngologie et de Chirurgie Cervico-faciale.

    This is an exploratory study, of bibliographical type, which aimed to verify and characterize the literary production of nurses on the topic of alcoholism published in the Annals of the Brazilian Nursing Congress, published in the period of 1998-2008. The sample consisted of 99 abstracts that were directly related to the topic. The data were categorized according to the assumptions of content analysis and resulted in seven categories of analysis. It was evident that there was an increase in the production on the subject over the period of 1998-2008, and that the alcoholic patient care was the theme most researched by nurses. It was concluded that, despite the increase in production on the subject, it is still in its infancy, suggesting that other studies of this nature are needed in order to map the production of nursing published in the scientific events in the area.

    Directory of Open Access Journals (Sweden)

    Hilary Macartney

    2011-12-01

    Full Text Available William Stirling’s Annals of the Artists of Spain (1848 appeared at a key moment in the emergence of art history as an academic discipline. It was the first scholarly history of Spanish art in English, and was well illustrated with engravings. But there was also an additional volume of Talbotype photographic illustrations. Photography, like art history, was still in its infancy, and William Henry Fox Talbot had only recently invented the negative-positive process which allowed multiple photographic images to be produced. The experimental supplementary volume, of which only 50 copies were printed, meant that the Annals became the first photographically illustrated book on art. The new process had many limitations, including chemical instability. Fading began immediately, and Stirling himself regarded the volume as a failed experiment. Nevertheless, it pointed the way in the use of photography, and photographically illustrated books, as essential tools of art history.

    To increase the knowledge base regarding pulmonology research in Brazil. A retrospective, observational study of the abstracts published in the Annals of the Brazilian Pulmonology and Phthisiology Conferences held from 1986 to 2004, quantifying the institutions of origin by geographic distribution and type, as well as categorizing the abstracts by study design and topic. A total of 6467 abstracts were published. The institutions of origin were located, variously, in the Southeast (3870 abstracts), South (1309), Northeast (783), Central-West (267) and North (84). There were 94 abstracts originating from foreign institutions, especially from institutions in Portugal (56.3%) and the United States (13.8%). Most of the studies (5825) were conducted in public Brazilian institutions. There were 4234 clinical studies, 1994 case reports and 239 original research articles. A marked, progressive increase was observed in the number of clinical studies and case reports during the period evaluated. Overall, the most common themes were tuberculosis and other infections diseases (25.2%), following by oncology (11.6%), interstitial lung diseases (8.8%) and thoracic surgery (8.5%). Nevertheless, the number of abstracts on each topic varied widely from year to year. Public Brazilian institutions are the principal sources of pulmonology research in Brazil. Such research activity is concentrated in the southeastern part of the country. Case reports account for one-third of this activity. Although there was great variability in the subjects addressed, diseases that are highly prevalent in Brazil, such as tuberculosis and other infections diseases, were the most common topics.

    How researchers' contributions relate to author order on the byline remains unclear. We sought to identify researchers' contributions associated with author order, and to explore the existence of author profiles. Observational study. Published record. 1139 authors of 119 research articles published in 2015 in the Annals of Internal Medicine. Presence or absence of 10 contributions, reported by each author, published in the journal. On average, first authors reported 7.1 contributions, second authors 5.2, middle authors 4.0, penultimate authors 4.5 and last authors 6.4 (pauthor made the greatest contributions to drafting the article, designing the study, analysing and interpreting the data, and providing study materials or patients. The second author contributed to data analysis as well and to drafting the article. The last author was most involved in obtaining the funding, critically revising the article, designing the study and providing support. Factor analysis yielded three author profiles-Thinker (study design, revision of article, obtaining funding), Soldier (providing material or patients, providing administrative and logistical support, collecting data) and Scribe (analysis and interpretation of data, drafting the article, statistical expertise). These profiles do not strictly correspond to byline position. First, second and last authors of research articles made distinct contributions to published research. Three authorship profiles can be used to summarise author contributions. These findings shed light on the organisation of clinical research teams and may help researchers discuss, plan and report authorship in a more transparent way. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Firth, Jean M

    1992-01-01

    The analysis of signals and systems using transform methods is a very important aspect of the examination of processes and problems in an increasingly wide range of applications. Whereas the initial impetus in the development of methods appropriate for handling discrete sets of data occurred mainly in an electrical engineering context (for example in the design of digital filters), the same techniques are in use in such disciplines as cardiology, optics, speech analysis and management, as well as in other branches of science and engineering. This text is aimed at a readership whose mathematical background includes some acquaintance with complex numbers, linear differen­ tial equations, matrix algebra, and series. Specifically, a familiarity with Fourier series (in trigonometric and exponential forms) is assumed, and an exposure to the concept of a continuous integral transform is desirable. Such a background can be expected, for example, on completion of the first year of a science or engineering degree cour...

  2. Hamlet's Transformation.

    Science.gov (United States)

    Usher, P. D.

    1997-12-01

    William Shakespeare's Hamlet has much evidence to suggest that the Bard was aware of the cosmological models of his time, specifically the geocentric bounded Ptolemaic and Tychonic models, and the infinite Diggesian. Moreover, Shakespeare describes how the Ptolemaic model is to be transformed to the Diggesian. Hamlet's "transformation" is the reason that Claudius, who personifies the Ptolemaic model, summons Rosencrantz and Guildenstern, who personify the Tychonic. Pantometria, written by Leonard Digges and his son Thomas in 1571, contains the first technical use of the word "transformation." At age thirty, Thomas Digges went on to propose his Perfit Description, as alluded to in Act Five where Hamlet's age is given as thirty. In Act Five as well, the words "bore" and "arms" refer to Thomas' vocation as muster-master and his scientific interest in ballistics. England's leading astronomer was also the father of the poet whose encomium introduced the First Folio of 1623. His oldest child Dudley became a member of the Virginia Company and facilitated the writing of The Tempest. Taken as a whole, such manifold connections to Thomas Digges support Hotson's contention that Shakespeare knew the Digges family. Rosencrantz and Guildenstern in Hamlet bear Danish names because they personify the Danish model, while the king's name is latinized like that of Claudius Ptolemaeus. The reason Shakespeare anglicized "Amleth" to "Hamlet" was because he saw a parallel between Book Three of Saxo Grammaticus and the eventual triumph of the Diggesian model. But Shakespeare eschewed Book Four, creating this particular ending from an infinity of other possibilities because it "suited his purpose," viz. to celebrate the concept of a boundless universe of stars like the Sun.

    Transformer apparatus is designed for measuring the amount of a paramagnetic substance dissolved or suspended in a diamagnetic liquid. The apparatus consists of a cluster of tubes, some of which are closed and have sealed within the diamagnetic substance without any of the paramagnetic material. The remaining tubes are open to flow of the mix- ture. Primary and secondary conductors are wrapped around the tubes in such a way as to cancel noise components and also to produce a differential signal on the secondaries based upon variations of the content of the paramagnetic material.

    In these uncertain times in the healthcare industry, administrators are asked to do more with less time and resources. Because of the extended roles they are playing in today's organizations, radiology administrators are looked upon as agents of change. What leadership skills do they need in this turbulent and uncertain healthcare environment? What are the trait's of tomorrow's leaders? The transformational leader is the one who will guide us through this changing healthcare environment. Several behavioral patterns emerge as important traits for tomorrow's leaders to have-individual consideration, intellectual stimulation and charisma. Tomorrow's leader must view each person as an individual, showing genuine concern and belief in each person's ability to perform. Transformational leaders stimulate others by encouraging them to be curious and try new ideas. The final characteristic, charisma, is the ability to inspire others. Luckily, leaders are made, not born: today's leaders can learn to be responsive, to draw out new ideas from employees, and to communicate self-esteem, energy and enthusiasm.

    2011-02-01

    Metamaterials are artificial materials with versatile properties that can be tailored to fit almost any practical need and thus go well beyond what can be obtained with `natural' materials. Recent progress in developing optical metamaterials allows unprecedented extreme control over the flow of light at both the nano- and macroscopic scales. The innovative field of transformation optics, which is enabled by metamaterials, inspired researchers to take a fresh look at the very foundations of optics and helped to create a new paradigm for the science of light. Similar to general relativity, where time and space are curved, transformation optics shows that the space for light can also be bent in an almost arbitrary way. Most importantly, the optical space can be designed and engineered, opening up the fascinating possibility of controlling the flow of light with nanometer spatial precision. This new paradigm enables a number of novel optical devices guiding how, using metamaterials, the space for light can be curved in a pre-designed and well-controlled way. Metamaterials which incorporate the innovative theories of transformation optics are pertinent to the important areas of optical cloaking, optical black holes, super-resolution imaging, and other sci-fi-like devices. One such exciting device is an electromagnetic cloak that can bend light around itself, similar to the flow of water around a stone, making invisible both the cloak and the object hidden inside. Another important application is a flat hyperlens that can magnify the nanometer-scale features of an object that cannot be resolved with conventional optics. This could revolutionize the field of optical imaging, for instance, because such a meta-lens could become a standard add-on tool for microscopes. By enabling nanoscale resolution in optical microscopy, metamaterial-based transformation optics could allow one to literally see extremely small objects with the eye, including biological cells, viruses, and

  11. Transforming giants.

    Kanter, Rosabeth Moss

    2008-01-01

    Large corporations have long been seen as lumbering, inflexible, bureaucratic--and clueless about global developments. But recently some multinationals seem to be transforming themselves: They're engaging employees, moving quickly, and introducing innovations that show true connection with the world. Harvard Business School's Kanter ventured with a research team inside a dozen global giants--including IBM, Procter & Gamble, Omron, CEMEX, Cisco, and Banco Real--to discover what has been driving the change. After conducting more than 350 interviews on five continents, she and her colleagues came away with a strong sense that we are witnessing the dawn of a new model of corporate power: The coordination of actions and decisions on the front lines now appears to stem from widely shared values and a sturdy platform of common processes and technology, not from top-down decrees. In particular, the values that engage the passions of far-flung workforces stress openness, inclusion, and making the world a better place. Through this shift in what might be called their guidance systems, the companies have become as creative and nimble as much smaller ones, even while taking on social and environmental challenges of a scale that only large enterprises could attempt. IBM, for instance, has created a nonprofit partnership, World Community Grid, through which any organization or individual can donate unused computing power to research projects and see what is being done with the donation in real time. IBM has gained an inspiring showcase for its new technology, helped business partners connect with the company in a positive way, and offered individuals all over the globe the chance to contribute to something big.

    2007-08-01

    We propose a novel random fractional Fourier transform by randomizing the transform kernel function of the conventional fractional Fourier transform. The random fractional Fourier transform inherits the excellent mathematical properties from the fractional Fourier transform and can be easily implemented in optics. As a primary application the random fractional Fourier transform can be directly used in optical image encryption and decryption. The double phase encoding image encryption schemes can thus be modeled with cascaded random fractional Fourier transformers.

    2014-01-01

    Several tools are available to help evaluate the quality of clinical practice guidelines (CPG). The AGREE instrument (Appraisal of guidelines for research & evaluation) is the most consensual tool but it has been designed to assess CPG methodology only. The European federation of laboratory medicine (EFLM) recently designed a check-list dedicated to laboratory medicine which is supposed to be comprehensive and which therefore makes it possible to evaluate more thoroughly the quality of CPG in laboratory medicine. In the present work we test the comprehensiveness of this check-list on a sample of CPG written in French and published in Annales de biologie clinique (ABC). Thus we show that some work remains to be achieved before a truly comprehensive check-list is designed. We also show that there is some room for improvement for the CPG published in ABC, for example regarding the fact that some of these CPG do not provide any information about allowed durations of transport and of storage of biological samples before analysis, or about standards of minimal analytical performance, or about the sensitivities or the specificities of the recommended tests.

    We show that a fractional version of the finite Fourier transform may be defined by using prolate spheroidal wave functions of order zero. The transform is linear and additive in its index and asymptotically goes over to Namias's definition of the fractional Fourier transform. As a special case of this definition, it is shown that the finite Fourier transform may be inverted by using information over a finite range of frequencies in Fourier space, the inversion being sensitive to noise. Numerical illustrations for both forward (fractional) and inverse finite transforms are provided.

    2016-01-01

    Transformative governance is an approach to environmental governance that has the capacity to respond to, manage, and trigger regime shifts in coupled social-ecological systems (SESs) at multiple scales. The goal of transformative governance is to actively shift degraded SESs to alternative, more desirable, or more functional regimes by altering the structures and processes that define the system. Transformative governance is rooted in ecological theories to explain cross-scale dynamics in complex systems, as well as social theories of change, innovation, and technological transformation. Similar to adaptive governance, transformative governance involves a broad set of governance components, but requires additional capacity to foster new social-ecological regimes including increased risk tolerance, significant systemic investment, and restructured economies and power relations. Transformative governance has the potential to actively respond to regime shifts triggered by climate change, and thus future research should focus on identifying system drivers and leading indicators associated with social-ecological thresholds.

    The demand for alternative energy sources fuels the need for electric power and controls engineers to possess a practical understanding of transformers suitable for solar energy. Meeting that need, Distributed Photovoltaic Grid Transformers begins by explaining the basic theory behind transformers in the solar power arena, and then progresses to describe the development, manufacture, and sale of distributed photovoltaic (PV) grid transformers, which help boost the electric DC voltage (generally at 30 volts) harnessed by a PV panel to a higher level (generally at 115 volts or higher) once it is

    Energy Technology Data Exchange (ETDEWEB)

    Otsuka, K. [University of Tsukuba, Tsukuba (Japan)

    1997-09-20

    This paper explains the recent studies on martensitic transformation (M transformation). The classical theory on nucleation in M transformation gives non-realistic activation energy as large as 10{sup 4}eV for Fe system. Although various theoretical and experimental approaches have been attempted, a universal theory is not yet established. The {beta}{sub 1}(DO{sub 3})-{gamma}{sub 1} transformation of Cu- Al-Ni alloy was resolved as lattice-invariable deformation by introducing the second kind twin. Various subsequent comparative studies for alloy systems between a phenomenology and experimental results showed the validity of a phenomenology due to lattice-invariable deformation. In the thermodynamics of M transformation, it has been recognized that the mechanism of transformation is entirely different between athermal and isothermal transformations, however, a statistical thermodynamic model was proposed for dealing with these transformations integrally. The study on intelligent materials is under active investigation from the viewpoint of application of M transformation. 44 refs.

    Given that the basic purpose of all research in materials science and technology is to tailor the properties of materials to suit specific applications, phase transformations are the natural key to the fine-tuning of the structural, mechanical and corrosion properties. A basic understanding of the kinetics and mechanisms of phase transformation is therefore of vital importance. Apart from a few cases involving crystallographic martensitic transformations, all phase transformations are mediated by diffusion. Thus, proper control and understanding of the process of diffusion during nucleation, g

    1989-04-01

    The ability of Xenorhabdus nematophilus 19061/1 to be transformed by pHK17 plasmid DNA was studied and optimized. A number of factors, including culture conditions, stage of growth, transformation buffer pH, cation type and concentration required for the production of competency, washing, heat shock conditions, and cell-DNA ratio, were found to affect transformation significantly. On the basis of these observations, a procedure for the routine transformation of X. nematophilus 19061/1 at frequencies of 1 X 10(5) to 10 X 10(5) transformants per microgram of pHK17 plasmid DNA was developed. Maximum transformation was obtained when cells which had reached the mid- to late-logarithmic growth phase (total counts, 2.5 X 10(8) to 5 X 10(8) cells per ml) within 4.5 to 5.5 h were washed once in cold transformation buffer before they were suspended in the same buffer to 0.1 of their original volume. The highest transformation was obtained when dimethyl sulfoxide was added in two steps to the cells immediately before the DNA was added, after which the cell-DNA mixtures were incubated for 30 min on ice before they were given a 3-min heat shock at 37 degrees C. Following these treatments, the transformed cells were incubated in L broth-60 mM CaCl2 for 1 h before they were plated onto selective medium. We also were able to transform X. nematophilus 19061/1 with plasmid pBR325, and we transformed other species of Xenorhabdus with several common plasmids.

  9. Simplified fractional Fourier transforms.

    Science.gov (United States)

    Pei, S C; Ding, J J

    2000-12-01

    The fractional Fourier transform (FRFT) has been used for many years, and it is useful in many applications. Most applications of the FRFT are based on the design of fractional filters (such as removal of chirp noise and the fractional Hilbert transform) or on fractional correlation (such as scaled space-variant pattern recognition). In this study we introduce several types of simplified fractional Fourier transform (SFRFT). Such transforms are all special cases of a linear canonical transform (an affine Fourier transform or an ABCD transform). They have the same capabilities as the original FRFT for design of fractional filters or for fractional correlation. But they are simpler than the original FRFT in terms of digital computation, optical implementation, implementation of gradient-index media, and implementation of radar systems. Our goal is to search for the simplest transform that has the same capabilities as the original FRFT. Thus we discuss not only the formulas and properties of the SFRFT's but also their implementation. Although these SFRFT's usually have no additivity properties, they are useful for the practical applications. They have great potential for replacing the original FRFT's in many applications.

  17. Transformation optics and cloaking

    Science.gov (United States)

    McCall, Martin

    2013-11-01

    Invisibility, a long sought-for speculation in science fiction, has been turned into reality in the laboratory through the use of a theoretical technique called Transformation Optics. The principles of transformation optics show that any desired smooth deformation of the electromagnetic field can be implemented exactly by an appropriately engineered metamaterial. All demonstrations of cloaking to date have had limitations, however, reflecting our technological inability to implement the transformation optics algorithm exactly. However, the scientific principles leading to perfect invisibility are now established, and practical improvements on the initial designs are now occurring very rapidly. Most recently, researchers have re-examined transformation optics to include time as well as space, describing and then implementing the concept of a cloak that hides events, a conceptual breakout that promises many new applications. This review describes the general ideas underlying transformation optics, and how the various types of cloak based on these ideas have been implemented practically to date.

    Full Text Available Citrus is one of the world’s important fruit crops. Recently, citrus molecular genetics and biotechnology work have been accelerated in the world. Genetic transformation, a biotechnological tool, allows the release of improved cultivars with desirable characteristics in a shorter period of time and therefore may be useful in citrus breeding programs. Citrus transformation has now been achieved in a number of laboratories by various methods. Agrobacterium tumefaciens is used mainly in citrus transformation studies. Particle bombardment, electroporation, A. rhizogenes, and a new method called RNA interference are used in citrus transformation studies in addition to A. tumefaciens. In this review, we illustrate how different gene transformation methods can be employed in different citrus species.

    As advances in technology transform society, so must it transform how people interact with that technology. However, technology advances much faster than do society and people. Most people don't care how the technology works--they care only that it does work. Current models are unsatisfactory because people must understand more of the underlying technology than is needed to perform their jobs. The view of this evolution explored here proposes that the training and maintenance will rest in the...

    Xi, Yajun; Ge, Yaxin; Wang, Zeng-Yu

    Switchgrass (Panicum virgatum L.) is a highly productive warm-season C4 species that is being developed into a dedicated biofuel crop. This chapter describes a protocol that allows the generation of transgenic switchgrass plants by Agrobacterium tumefaciens-mediated transformation. Embryogenic calluses induced from caryopses or inflorescences were used as explants for inoculation with A. tumefaciens strain EHA105. Hygromycin phosphotransferase gene (hph) was used as the selectable marker and hygromycin was used as the selection agent. Calluses resistant to hygromycin were obtained after 5-6 weeks of selection. Soil-grown switchgrass plants were regenerated about 6 months after callus induction and Agrobacterium-mediated transformation.

This holds true for the time stationary point processes too. We show that several well known stochastical equivalences as e.g. that between the H 2 renewal process and the Interrupted Poisson Process (IPP can be expressed by the similarity transformations of MAPs. In the appendix the valid region of similarity transformations for two-state MAPs is characterized.

    2013-01-01

    The need to run complex workflows for a high energy physics experiment such as ATLAS has always been present. However, as computing resources have become even more constrained, compared to the wealth of data generated by the LHC, the need to use resources efficiently and manage complex workflows within a single grid job have increased. In ATLAS, a new Job Transform framework has been developed that we describe in this paper. This framework manages the multiple execution steps needed to `transform' one data type into another (e.g., RAW data to ESD to AOD to final ntuple) and also provides a consistent interface for the ATLAS production system. The new framework uses a data driven workflow definition which is both easy to manage and powerful. After a transform is defined, jobs are expressed simply by specifying the input data and the desired output data. The transform infrastructure then executes only the necessary substeps to produce the final data products. The global execution cost of running the job is mini...

    2007-09-01

    With the completion of the poplar tree genome database, Populus species have become one of the most useful model systems for the study of woody plant biology. Populus tremuloides (quaking aspen) is the most wide-spread tree species in North America, and its rapid growth generates the most abundant wood-based biomass out of any other plant species. To study such beneficial traits, there is a need for easier and more efficient transformation procedures that will allow the study of large numbers of tree genes. We have developed transformation procedures that are suitable for high-throughput format transformations using either Agrobacterium tumefaciens to produce transformed trees or Agrobacterium rhizogenes to generate hairy roots. Our method uses Agrobacterium inoculated aspen seedling hypocotyls followed by direct thidiazuron (TDZ)-mediated shoot regeneration on selective media. Transformation was verified through beta-glucuronidase (GUS) reporter gene expression in all tree tissues, PCR amplification of appropriate vector products from isolated genomic DNA, and northern hybridization of incorporated and expressed transgenes. The hairy root protocol follows the same inoculation procedures and was tested using GUS reporter gene integration and antibiotic selection. The benefit of these procedures is that they are simple and efficient, requiring no maintenance of starting materials and allowing fully formed transgenic trees (or hairy roots) to be generated in only 3-4 months, rather than the 6-12 months required by more traditional methods. Likewise, the fact that the protocols are amenable to high-throughput formats makes them better suited for large-scale functional genomics studies in poplars.

  6. Rainbow Fourier Transform

    Science.gov (United States)

    Alexandrov, Mikhail D.; Cairns, Brian; Mishchenko, Michael I.

    2012-01-01

    We present a novel technique for remote sensing of cloud droplet size distributions. Polarized reflectances in the scattering angle range between 135deg and 165deg exhibit a sharply defined rainbow structure, the shape of which is determined mostly by single scattering properties of cloud particles, and therefore, can be modeled using the Mie theory. Fitting the observed rainbow with such a model (computed for a parameterized family of particle size distributions) has been used for cloud droplet size retrievals. We discovered that the relationship between the rainbow structures and the corresponding particle size distributions is deeper than it had been commonly understood. In fact, the Mie theory-derived polarized reflectance as a function of reduced scattering angle (in the rainbow angular range) and the (monodisperse) particle radius appears to be a proxy to a kernel of an integral transform (similar to the sine Fourier transform on the positive semi-axis). This approach, called the rainbow Fourier transform (RFT), allows us to accurately retrieve the shape of the droplet size distribution by the application of the corresponding inverse transform to the observed polarized rainbow. While the basis functions of the proxy-transform are not exactly orthogonal in the finite angular range, this procedure needs to be complemented by a simple regression technique, which removes the retrieval artifacts. This non-parametric approach does not require any a priori knowledge of the droplet size distribution functional shape and is computationally fast (no look-up tables, no fitting, computations are the same as for the forward modeling).

    2013-01-01

    A component level dc transformer is described in which no alternating currents or voltages are present. It operates by combining features of a homopolar motor and a homopolar generator, both de devices, such that the output voltage of a de power supply can be stepped up (or down) with a corresponding step down (or up) in current. The basic theory for this device is developed, performance predictions are made, and the results from a small prototype are presented. Based on demonstrated technology in the literature, this de transformer should be scalable to low megawatt levels, but it is more suited to high current than high voltage applications. Significant development would be required before it could achieve the kilovolt levels needed for de power transmission.

    2011-06-10

    Metamaterials and transformation optics play substantial roles in various branches of optical science and engineering by providing schemes to tailor electromagnetic fields into desired spatial patterns. We report a theoretical study showing that by designing and manipulating spatially inhomogeneous, nonuniform conductivity patterns across a flake of graphene, one can have this material as a one-atom-thick platform for infrared metamaterials and transformation optical devices. Varying the graphene chemical potential by using static electric field yields a way to tune the graphene conductivity in the terahertz and infrared frequencies. Such degree of freedom provides the prospect of having different "patches" with different conductivities on a single flake of graphene. Numerous photonic functions and metamaterial concepts can be expected to follow from such a platform.

  1. Housing market transformation

    Energy Technology Data Exchange (ETDEWEB)

    Fawcett, Tina; Boardman, Brenda (Environmental Change Inst., Univ. of Oxford, Oxford (United Kingdom))

    2009-07-01

    Reducing energy use in the existing building stock requires a substantial and rapid transformation of the whole sector. Using a market transformation approach provides a useful framework and poses some new problems in comparison with appliances: houses don't break down in the same way as fridges, but can be improved piecemeal. The Energy Performance in Buildings Directive provides the foundation (and the x axis) for policies to achieve substantial reductions in residential energy use and carbon emissions by 2050. The technology is known, but has to be chosen by the householder it cannot be incorporated in the factory by a manufacturer. Education and awareness are, therefore, more important, both for the householder and for the installers. What is the role, if any, of mandatory minimum standards? The types and mix of policies require a clear understanding of the challenges provided by low-income groups, capital shortages, the length of residence in the house, the landlord-tenant split and user knowledge. This paper reviews the challenges and examines the extent to which the well-known market transformation theories work for the housing sector. Most of the examples are from the UK, but have been developed into generic principles.

  2. Transformation method and wave control

    Chang, Zheng; Hu, Jin; Hu, Geng-Kai

    2010-12-01

    Transformation method provides an efficient way to control wave propagation by materials. The transformed relations for field and material during a transformation are essential to fulfill this method. We propose a systematic method to derive the transformed relations for a general physic process, the constraint conditions are obtained by considering geometrical and physical constraint during a mapping. The proposed method is applied to Navier's equation for elastodynamics, Helmholtz's equation for acoustic wave and Maxwell's equation for electromagnetic wave, the corresponding transformed relations are derived, which can be used in the framework of transformation method for wave control. We show that contrary to electromagnetic wave, the transformed relations are not uniquely determined for elastic wave and acoustic wave, so we have a freedom to choose them differently. Using the obtained transformed relations, we also provide some examples for device design, a concentrator for elastic wave, devices for illusion acoustic and illusion optics are conceived and validated by numerical simulations.

    2006-12-01

    A novel transformation system, in which neither a nonphysiological concentration of Ca2+ and temperature shifts nor electronic shocks were required, was developed to determine whether Escherichia coli is naturally transformable. In the new protocol, E. coli was cultured normally to the stationary phase and then cultured statically at 37 degrees C in Luria-Bertani broth. After static culture, transformation occurred in bacteria spread on Luria-Bertani plates. The protein synthesis inhibitor chloramphenicol inhibited this transformation process. The need for protein synthesis in plated bacteria suggests that the transformation of E. coli in this new system is regulated physiologically.

    We present algorithms for fast and stable approximation of the Hermite transform of a compactly supported function on the real line, attainable via an application of a fast algebraic algorithm for computing sums associated with a three-term relation. Trade-offs between approximation in bandlimit (in the Hermite sense) and size of the support region are addressed. Numerical experiments are presented that show the feasibility and utility of our approach. Generalizations to any family of orthogonal polynomials are outlined. Applications to various problems in tomographic reconstruction, including the determination of protein structure, are discussed.

    1993-11-01

    The characteristics of martensitic transformations in solids are largely determined by the elastic strain that develops as martensite particles grow and interact. To study the development of microstructure, a finite-element computer simulation model was constructed to mimic the transformation process. The transformation is athermal and simulated at each incremental step by transforming the cell which maximizes the decrease in the free energy. To determine the free energy change, the elastic energy developed during martensite growth is calculated from the theory of linear elasticity for elastically homogeneous media, and updated as the transformation proceeds.

    2012-06-01

    Full Text Available The urgency of charting pathways to sustainability that keep human societies within a "safe operating space" has now been clarified. Crises in climate, food, biodiversity, and energy are already playing out across local and global scales and are set to increase as we approach critical thresholds. Drawing together recent work from the Stockholm Resilience Centre, the Tellus Institute, and the STEPS Centre, this commentary article argues that ambitious Sustainable Development Goals are now required along with major transformation, not only in policies and technologies, but in modes of innovation themselves, to meet them. As examples of dryland agriculture in East Africa and rural energy in Latin America illustrate, such "transformative innovation" needs to give far greater recognition and power to grassroots innovation actors and processes, involving them within an inclusive, multi-scale innovation politics. The three dimensions of direction, diversity, and distribution along with new forms of "sustainability brokering" can help guide the kinds of analysis and decision making now needed to safeguard our planet for current and future generations.

  11. 7 transformations of leadership.

    Science.gov (United States)

    Rooke, David; Torbert, William R

    2005-04-01

    Most developmental psychologists agree that what differentiates one leader from another is not so much philosophy of leadership, personality, or style of management. Rather, it's internal "action logic"--how a leader interprets the surroundings and reacts when his or her power or safety is challenged. Relatively few leaders, however, try to understand their action logic, and fewer still have explored the possibility of changing it. They should, because leaders who undertake this voyage of personal understanding and development can transform not only their own capabilities but also those of their companies. The authors draw on 25 years of consulting experience and collaboration with psychologist Susanne Cook-Greuter to present a typology of leadership based on the way managers personally make sense of the world around them. Rooke and Torbert classify leaders into seven distinct actionlogic categories: Opportunists, Diplomats, Experts, Achievers, Individualists, Strategists, and Alchemists-the first three associated with below-average performance, the latter four with medium to high performance. These leadership styles are not fixed, the authors say, and executives who are willing to work at developing themselves and becoming more self-aware can almost certainly move toward one of the more effective action logics. A Diplomat, for instance, can succeed through hard work and self-reflection at transforming himself into a Strategist. Few people may become Alchemists, but many will have the desire and potential to become Individualists and Strategists. Corporations that help their executives and leadership teams to examine their action logics can reap rich rewards.

  12. Magnetic Materials for Current Transformers

    CERN Document Server

    Aguilera, S; Ruffieux, P

    2013-01-01

    At CERN, the circulating beam current measurement is provided by two types of transformers, the Direct Current Current Transformers (DCCT) and the Fast Beam Current Transformers (FBCT). Each type of transformer requires different magnetic characteristics regarding parameters such as permeability, coercivity and shape of the magnetization curve. Each transformer is built based on toroidal cores of a magnetic material which gives these characteristics. For example, DCCTs consist of three cores, two for the measurement of the DC component and one for the AC component. In order to study the effect of changes in these parameters on the current transformers, several interesting raw materials based on their as-cast properties were selected with the annealing process used to tune their properties for the individual needs of each transformer. First annealing tests show that the magnetization curve, and therefore the permeability, of the material can be modified, opening the possibility for building and studying a vari...

    Graphs are widely used to represent structural information in the form of objects and connections between them. Graph transformation is the rule-based manipulation of graphs, an increasingly important concept in computer science and related fields. This is the first textbook treatment of the algebraic approach to graph transformation, based on algebraic structures and category theory. Part I is an introduction to the classical case of graph and typed graph transformation. In Part II basic and advanced results are first shown for an abstract form of replacement systems, so-called adhesive high-level replacement systems based on category theory, and are then instantiated to several forms of graph and Petri net transformation systems. Part III develops typed attributed graph transformation, a technique of key relevance in the modeling of visual languages and in model transformation. Part IV contains a practical case study on model transformation and a presentation of the AGG (attributed graph grammar) tool envir...

  14. Transformations of emotional experience.

    Science.gov (United States)

    de Cortiñas, Lia Pistiner

    2013-06-01

    In this paper the author approaches mental pain and the problems in a psychoanalytic treatment of patients with difficulties in the psychic transformation of their emotional experiences. The author is interested in the symbolic failure related to the obstruction of development of phantasies, dreams, dream-thoughts, etc. She differentiates symbolization disturbances related to hypertrophic projective identification from a detention of these primitive communications and emotional isolation. She puts forward the conjecture that one factor in the arrest of this development is the detention of projective identifications and that, when this primitive means of communication is re-established in a container-contained relationship of mutual benefit, this initiates the development of a symbolization process that can replace the pathological 'protection'. Another hypothesis she develops is that of inaccessible caesuras that, associated with the detention of projective identification, obstruct any integrative or interactive movement. This caesura and the detention of projective identifications affect mental functions needed for dealing with mental pain. The personality is left with precarious mental equipment for transforming emotional experiences. How can a psychoanalytical process stimulate the development of creative symbolization, transforming the emotional experiences and leading towards mental growth? The author approaches the clinical problem with the metaphor of the psychic birth of emotional experience. The modulation of mental pain in a container-contained relationship is a central problem for the development of the human mind. For discovering and giving a meaning to emotional experience, the infant depends on reverie, a function necessary in order to develop an evolved consciousness capable of being aware, which is different from the rudimentary consciousness that perceives but does not understand. The development of mature mental equipment is associated with the

  15. Combined Reduced-Rank Transform

    Directory of Open Access Journals (Sweden)

    Anatoli Torokhti

    2006-04-01

    Full Text Available We propose and justify a new approach to constructing optimal nonlinear transforms of random vectors. We show that the proposed transform improves such characteristics of {rank-reduced} transforms as compression ratio, accuracy of decompression and reduces required computational work. The proposed transform ${mathcal T}_p$ is presented in the form of a sum with $p$ terms where each term is interpreted as a particular rank-reduced transform. Moreover, terms in ${mathcal T}_p$ are represented as a combination of three operations ${mathcal F}_k$, ${mathcal Q}_k$ and ${oldsymbol{varphi}}_k$ with $k=1,ldots,p$. The prime idea is to determine ${mathcal F}_k$ separately, for each $k=1,ldots,p$, from an associated rank-constrained minimization problem similar to that used in the Karhunen--Lo`{e}ve transform. The operations ${mathcal Q}_k$ and ${oldsymbol{varphi}}_k$ are auxiliary for f/inding ${mathcal F}_k$. The contribution of each term in ${mathcal T}_p$ improves the entire transform performance. A corresponding unconstrained nonlinear optimal transform is also considered. Such a transform is important in its own right because it is treated as an optimal filter without signal compression. A rigorous analysis of errors associated with the proposed transforms is given.

  16. INFORMATION MODEL OF SOCIAL TRANSFORMATIONS

    Directory of Open Access Journals (Sweden)

    Мария Васильевна Комова

    2013-09-01

    Full Text Available The social transformation is considered as a process of qualitative changes of the society, creating a new level of organization in all areas of life, in different social formations, societies of different types of development. The purpose of the study is to create a universal model for studying social transformations based on their understanding as the consequence of the information exchange processes in the society. After defining the conceptual model of the study, the author uses the following methods: the descriptive method, analysis, synthesis, comparison.Information, objectively existing in all elements and systems of the material world, is an integral attribute of the society transformation as well. The information model of social transformations is based on the definition of the society transformation as the change in the information that functions in the society’s information space. The study of social transformations is the study of information flows circulating in the society and being characterized by different spatial, temporal, and structural states. Social transformations are a highly integrated system of social processes and phenomena, the nature, course and consequences of which are affected by the factors representing the whole complex of material objects. The integrated information model of social transformations foresees the interaction of the following components: social memory, information space, and the social ideal. To determine the dynamics and intensity of social transformations the author uses the notions of "information threshold of social transformations" and "information pressure".Thus, the universal nature of information leads to considering social transformations as a system of information exchange processes. Social transformations can be extended to any episteme actualized by social needs. The establishment of an information threshold allows to simulate the course of social development, to predict the

    2009-08-01

    Truncated expansions such as Zernike polynomials provide a powerful approach for describing wavefront data. However, many simple calculations with data in this form can require significant computational effort. Important examples include recentering, renormalizing, and translating the wavefront data. This paper describes a technique whereby these operations and many others can be performed with a simple matrix approach using monomials. The technique may be applied to other expansions by reordering the data and applying transformations. The key is the use of the vectorization operator to convert data between vector and matrix descriptions. With this conversion, one-dimensional polynomial techniques may be employed to perform separable operations. Examples are also given for differentiation and integration of wavefronts.

    A Fourier transform spectrometer (FTS) data acquisition system includes an FTS spectrometer that receives a spectral signal and a laser signal. The system further includes a wideband detector, which is in communication with the FTS spectrometer and receives the spectral signal and laser signal from the FTS spectrometer. The wideband detector produces a composite signal comprising the laser signal and the spectral signal. The system further comprises a converter in communication with the wideband detector to receive and digitize the composite signal. The system further includes a signal processing unit that receives the composite signal from the converter. The signal processing unit further filters the laser signal and the spectral signal from the composite signal and demodulates the laser signal, to produce velocity corrected spectral data.

  1. A piezoelectric transformer

    Won, C. C.

    1993-01-01

    This work describes a modeling and design method whereby a piezoelectric system is formulated by two sets of second-order equations, one for the mechanical system, and the other for the electrical system, coupled through the piezoelectric effect. The solution to this electromechanical coupled system gives a physical interpretation of the piezoelectric effect as a piezoelectric transformer that is a part of the piezoelectric system, which transfers the applied mechanical force into a force-controlled current source, and short circuit mechanical compliance into capacitance. It also transfers the voltage source into a voltage-controlled relative velocity input, and free motional capacitance into mechanical compliance. The formulation and interpretation simplify the modeling of smart structures and lead to physical insight that aids the designer. Due to its physical realization, the smart structural system can be unconditional stable and effectively control responses. This new concept has been demonstrated in three numerical examples for a simple piezoelectric system.

    This paper describes welfare state transformation in OECD countries since the 1970s against the background of the post-war settlement. Relying on quantitative macro-data and qualitative information from the literature, we show that welfare states have con-verged, especially regarding various...... spending measures, and also to a certain extent in some qualitative policy-making patterns. What has emerged can best be described as the ‘supply-side welfare state’ model, and this overall orientation is reflected in many wel-fare state areas. We differ from earlier prognoses of a race to the bottom...... by generous welfare states and disagree with the view that a supply-side orientation equals ‘lean government’ in terms of social expenditure. But convergence implies that the space to maneuver has shrunk for policy-makers. The consequences of the 2008 financial crisis for welfare states are difficult...

    2017-01-01

    Mechanical metamaterials are engineered materials whose structures give them novel mechanical properties, including negative Poisson's ratios, negative compressibilities and phononic bandgaps. Of particular interest are systems near the point of mechanical instability, which recently have been shown to distribute force and motion in robust ways determined by a nontrivial topological state. Here we discuss the classification of and propose a design principle for mechanical metamaterials that can be easily and reversibly transformed between states with dramatically different mechanical and acoustic properties via a soft strain. Remarkably, despite the low energetic cost of this transition, quantities such as the edge stiffness and speed of sound can change by orders of magnitude. We show that the existence and form of a soft deformation directly determines floppy edge modes and phonon dispersion. Finally, we generalize the soft strain to generate domain structures that allow further tuning of the material.

  6. Neutrosophic Hough Transform

    Directory of Open Access Journals (Sweden)

    Ümit Budak

    2017-12-01

    Full Text Available Hough transform (HT is a useful tool for both pattern recognition and image processing communities. In the view of pattern recognition, it can extract unique features for description of various shapes, such as lines, circles, ellipses, and etc. In the view of image processing, a dozen of applications can be handled with HT, such as lane detection for autonomous cars, blood cell detection in microscope images, and so on. As HT is a straight forward shape detector in a given image, its shape detection ability is low in noisy images. To alleviate its weakness on noisy images and improve its shape detection performance, in this paper, we proposed neutrosophic Hough transform (NHT. As it was proved earlier, neutrosophy theory based image processing applications were successful in noisy environments. To this end, the Hough space is initially transferred into the NS domain by calculating the NS membership triples (T, I, and F. An indeterminacy filtering is constructed where the neighborhood information is used in order to remove the indeterminacy in the spatial neighborhood of neutrosophic Hough space. The potential peaks are detected based on thresholding on the neutrosophic Hough space, and these peak locations are then used to detect the lines in the image domain. Extensive experiments on noisy and noise-free images are performed in order to show the efficiency of the proposed NHT algorithm. We also compared our proposed NHT with traditional HT and fuzzy HT methods on variety of images. The obtained results showed the efficiency of the proposed NHT on noisy images.

    The vectorial extension of the Ribaucour transformation for the Lame equations of orthogonal conjugates nets in multidimensions is given. We show that the composition of two vectorial Ribaucour transformations with appropriate transformation data is again a vectorial Ribaucour transformation, from which it follows the permutability of the vectorial Ribaucour transformations. Finally, as an example we apply the vectorial Ribaucour transformation to the Cartesian background.

    2013-08-01

    We studied the Coulombic transformation of potential in momentum space. The Coulombic transformation is defined as a unitary transformation in momentum space, which is equivalent of the Coulomb-Fourier transformation in coordinate space. The analytic continuation scheme avoids the difficulty which is occurred from the singularity of the Coulomb wave function in momentum space. We adopted the point method to perform the analytic continuation. The validity of the new scheme is checked by comparing with the analytic solution for the Malfliet-Tjon potential. Numerical calculation of the integration was done by separating into four intervals. We demonstrate the high accuracy of our calculation.

  11. Microfabricated Bulk Piezoelectric Transformers

    Science.gov (United States)

    Barham, Oliver M.

    Piezoelectric voltage transformers (PTs) can be used to transform an input voltage into a different, required output voltage needed in electronic and electro- mechanical systems, among other varied uses. On the macro scale, they have been commercialized in electronics powering consumer laptop liquid crystal displays, and compete with an older, more prevalent technology, inductive electromagnetic volt- age transformers (EMTs). The present work investigates PTs on smaller size scales that are currently in the academic research sphere, with an eye towards applications including micro-robotics and other small-scale electronic and electromechanical sys- tems. PTs and EMTs are compared on the basis of power and energy density, with PTs trending towards higher values of power and energy density, comparatively, indicating their suitability for small-scale systems. Among PT topologies, bulk disc-type PTs, operating in their fundamental radial extension mode, and free-free beam PTs, operating in their fundamental length extensional mode, are good can- didates for microfabrication and are considered here. Analytical modeling based on the Extended Hamilton Method is used to predict device performance and integrate mechanical tethering as a boundary condition. This model differs from previous PT models in that the electric enthalpy is used to derive constituent equations of motion with Hamilton's Method, and therefore this approach is also more generally applica- ble to other piezoelectric systems outside of the present work. Prototype devices are microfabricated using a two mask process consisting of traditional photolithography combined with micropowder blasting, and are tested with various output electri- cal loads. 4mm diameter tethered disc PTs on the order of .002cm. 3 , two orders smaller than the bulk PT literature, had the followingperformance: a prototype with electrode area ratio (input area / output area) = 1 had peak gain of 2.3 (+/- 0.1), efficiency of 33 (+/- 0

  13. Color image encryption based on gyrator transform and Arnold transform

    Science.gov (United States)

    Sui, Liansheng; Gao, Bo

    2013-06-01

    A color image encryption scheme using gyrator transform and Arnold transform is proposed, which has two security levels. In the first level, the color image is separated into three components: red, green and blue, which are normalized and scrambled using the Arnold transform. The green component is combined with the first random phase mask and transformed to an interim using the gyrator transform. The first random phase mask is generated with the sum of the blue component and a logistic map. Similarly, the red component is combined with the second random phase mask and transformed to three-channel-related data. The second random phase mask is generated with the sum of the phase of the interim and an asymmetrical tent map. In the second level, the three-channel-related data are scrambled again and combined with the third random phase mask generated with the sum of the previous chaotic maps, and then encrypted into a gray scale ciphertext. The encryption result has stationary white noise distribution and camouflage property to some extent. In the process of encryption and decryption, the rotation angle of gyrator transform, the iterative numbers of Arnold transform, the parameters of the chaotic map and generated accompanied phase function serve as encryption keys, and hence enhance the security of the system. Simulation results and security analysis are presented to confirm the security, validity and feasibility of the proposed scheme.

    2008-01-01

    Full Text Available The consumption of electric power is constantly increasing due to industrialization and population growth. This results in much more severe operating conditions of transformers, the most important electrical devices that make integral parts of power transmission and distribution systems. The designed operating life of the majority of worldwide transformers has already expired, which puts the increase of transformer reliability and operating life extension in the spotlight. Transformer oil plays a very important role in transformer operation, since it provides insulation and cooling, helps extinguishing sparks and dissolves gases formed during oil degradation. In addition to this, it also dissolves moisture and gases from cellulose insulation and atmosphere it is exposed to. Further and by no means less important functions of transformer are of diagnostic purpose. It has been determined that examination and inspection of insulation oil provide 70% of information on transformer condition, which can be divided in three main groups: dielectric condition, aged transformer condition and oil degradation condition. By inspecting and examining the application oil it is possible to determine the condition of insulation, oil and solid insulation (paper, as well as irregularities in transformer operation. All of the above-mentioned reasons and facts create ground for the subject of this research covering two stages of transformer oil life cycle: (1 proactive maintenance and monitoring of transformer oils in the course of utilization with reference to influence of transformer oil condition on paper insulation condition, as well as the condition of the transformer itself; (2 regeneration of transformer oils for the purpose of extension of utilization period and paper insulation revitalization potential by means of oil purification. The study highlights advantages of oil-paper insulation revitalization over oil replacement. Besides economic, there are

  15. Memory of Power Transformed

    Directory of Open Access Journals (Sweden)

    Kalina Maleska

    2014-11-01

    Full Text Available This essay is focused on the phenomenon of power. Special attention is paid to the past understanding, research and explanation of what power is, and how it has been understood throughout history. Traditionally, power has referred to authority, influence, control. The research of literary works, however, has led me to the realization that the notion of power is understood in different terms in literature in comparison to how it is explained in philosophy and the social sciences. In order to contribute to the broader understanding of power from a literary point of view, this essay examines many questions concerning this phenomenon, such as: how does the past understanding of power determine how it is accepted and interpreted in the present? How are the success of the present efforts and initiatives affected by the memory of power? The essay attempts to show that the memory of the notion of power is not and cannot be fixed and given once and for all. Therefore, the literary examples provided demonstrate how the definitions of power given in the past are transformed and transfigured by present literary works, which show how we may “forget” what we know about this phenomenon, and define it from a new perspective.

  19. Dependency Parsing with Transformed Feature

    Directory of Open Access Journals (Sweden)

    Fuxiang Wu

    2017-01-01

    Full Text Available Dependency parsing is an important subtask of natural language processing. In this paper, we propose an embedding feature transforming method for graph-based parsing, transform-based parsing, which directly utilizes the inner similarity of the features to extract information from all feature strings including the un-indexed strings and alleviate the feature sparse problem. The model transforms the extracted features to transformed features via applying a feature weight matrix, which consists of similarities between the feature strings. Since the matrix is usually rank-deficient because of similar feature strings, it would influence the strength of constraints. However, it is proven that the duplicate transformed features do not degrade the optimization algorithm: the margin infused relaxed algorithm. Moreover, this problem can be alleviated by reducing the number of the nearest transformed features of a feature. In addition, to further improve the parsing accuracy, a fusion parser is introduced to integrate transformed and original features. Our experiments verify that both transform-based and fusion parser improve the parsing accuracy compared to the corresponding feature-based parser.

    Alfredo Vazquez Carazo

    2016-04-01

    Full Text Available Piezoelectric transformers (PTs are solid-state devices that transform electrical energy into electrical energy by means of a mechanical vibration. These devices are manufactured using piezoelectric materials that are driven at resonance. With appropriate design and circuitry, it is possible to step up and step down the voltages between the input and output sections of the piezoelectric transformer, without making use of magnetic materials and obtaining excellent conversion efficiencies. The initial concept of a piezoelectric ceramic transformer was proposed by Charles A. Rosen in 1954. Since then, the evolution of piezoelectric transformers through history has been linked to the relevant work of some excellent researchers as well as to the evolution in materials, manufacturing processes, and driving circuit techniques. This paper summarizes the historical evolution of the technology.

This work proposes an approach of parallel graph transformations which enables dependent transformation rules to be executed in parallel.

  9. Empirical substantiation of possible connection between content radiocarbon in atmosphere and frequency of the catastrophic phenomena in Europe in last millennium (on the basis of historical records or annals)

    Science.gov (United States)

    Boychenko, S. G.; Voloshchuk, V. M.

    The method of research of frequency of the natural catastrophic phenomena and processes in territory of Ukraine, the Western Europe and Russian (East-Europe) plain in last millennium was worked out on the basis of the analysis of historical records or annals. Empirical time series of frequency of the catastrophic weather phenomena in territory of Ukraine for the period of 800-1800 (droughts, rainy summers, floods and high waters, cold winters, late springs, colds at the beginning of a summer, catastrophic thunderstorms, catastrophic storms, earthquakes etc.) are constructed. The anomalies of temperature of Europe for last millennium were also considered. Non-monotonic connection of frequency of catastrophic processes and the phenomena on territory of Ukraine with global anomalies of content of radiocarbon in atmosphere in last millennium is established. The basic result of this research is: frequency of catastrophic natural phenomena in the territory of Europe was higher, when the anomalies of content of radiocarbon in atmosphere deviated in this or that direction from some optimum level. A quantitative estimation of the established effect are obtained with help for a parabolic model of dependence of frequency of phenomena from of century anomalies of content of radiocarbon in atmosphere in Europe. Estimations of empirical constants of this mathematical model for all considered phenomena are received. It is known, that the content of radiocarbon in an atmosphere is one of indicators of long-term solar activity. The hypothesis earlier offered by another scientists concerning connections between century temperature anomalies in Europe and long-terms cycles of solar activity is considered. Unfortunately, the radiocarbon indicator of solar activity is essentially spoiled by anthropogenic influence (Suess's effect, bomb-effect) for last ~150 years. As a basic result of this research semi-empirical model of parabolic dependence of frequency of the catastrophic phenomena

  10. Transformative environmental governance | Science Inventory ...

    Science.gov (United States)

    Transformative governance is an approach to environmental governance that has the capacity to respond to, manage, and trigger regime shifts in coupled social-ecological systems (SESs) at multiple scales. The goal of transformative governance is to actively shift degraded SESs to alternative, more desirable, or more functional regimes by altering the structures and processes that define the system. Transformative governance is rooted in ecological theories to explain cross-scale dynamics in complex systems, as well as social theories of change, innovation, and technological transformation. Similar to adaptive governance, transformative governance involves a broad set of governance components, but requires additional capacity to foster new social-ecological regimes including increased risk tolerance, significant systemic investment, and restructured economies and power relations. Transformative governance has the potential to actively respond to regime shifts triggered by climate change, and thus future research should focus on identifying system drivers and leading indicators associated with social-ecological thresholds.

    The US Army Engineering & Support Center, Huntsville (USAESCH), and the US Marine Corps Base (MCB), Okinawa, Japan retained Idaho National Laboratory (INL) to conduct a Transformer Efficiency Assessment of “key” transformers located at multiple military bases in Okinawa, Japan. The purpose of this assessment is to support the Marine Corps Base, Okinawa in evaluating medium voltage distribution transformers for potential efficiency upgrades. The original scope of work included the MCB providing actual transformer nameplate data, manufacturer’s factory test sheets, electrical system data (kWh), demand data (kWd), power factor data, and electricity cost data. Unfortunately, the MCB’s actual data is not available and therefore making it necessary to de-scope the original assessment. Note: Any similar nameplate data, photos of similar transformer nameplates, and basic electrical details from one-line drawings (provided by MCB) are not a replacement for actual load loss test data. It is recommended that load measurements are performed on the high and low sides of transformers to better quantify actual load losses, demand data, and power factor data. We also recommend that actual data, when available, be inserted by MCB Okinawa where assumptions have been made and then the LCC analysis updated. This report covers a generalized assessment of modern U.S. transformers in a three level efficiency category, Low-Level efficiency, Medium-Level efficiency, and High-Level efficiency.

    Conventional plant transformation typically includes preparation of competent plant cells or tissues, delivery of foreign genes into cells, transformed cell selection with stable incorporated foreign genes, and regeneration of transformed cells into intact plants. This process traditionally relies on tissue culture, and cotton has not been an exception to this paradigm. Though the commercialization of transgenic cotton is a resounding success, cotton transformation, which is the first step in producing transgenic cotton, is a burdensome process since there is a very long tissue culture process and a limited number of cultivars that can be regenerated. An improved process which is easier to handle and more genotype independent could efficiently generate more transgenic plants and allow meaningful analyses of gene function and transgenic plants. Cotton pistil drip by inoculating Agrobacterium tumefaciens onto the pistil after pollination gave rise to stable transformants. Since this transformation process in cotton occurs following pollination and during fertilization (postanthesis) but not during preanthesis as in Arabidopsis, the mechanism by which Agrobacterium enters plant cells and integrates into the cotton genome may differ from that in Arabidopsis. This chapter provides the detailed protocol for pistil drip, a simple in planta transformation method without the plant tissue culture process.

  14. Lorentz Transformations from Intrinsic Symmetries

    Directory of Open Access Journals (Sweden)

    Sheng D. Chao

    2016-09-01

    Full Text Available We reveal the frame-exchange space-inversion (FESI symmetry and the frame-exchange time-inversion (FETI symmetry in the Lorentz transformation and propose a symmetry principle stating that the space-time transformation between two inertial frames is invariant under the FESI or the FETI transformation. In combination with the principle of relativity and the presumed nature of Euclidean space and time, the symmetry principle is employed to derive the proper orthochronous Lorentz transformation without assuming the constancy of the speed of light and specific mathematical requirements (such as group property a priori. We explicitly demonstrate that the constancy of the speed of light in all inertial frames can be derived using the velocity reciprocity property, which is a deductive consequence of the space–time homogeneity and the space isotropy. The FESI or the FETI symmetry remains to be preserved in the Galilean transformation at the non-relativistic limit. Other similar symmetry operations result in either trivial transformations or improper and/or non-orthochronous Lorentz transformations, which do not form groups.

  15. Conduction-coupled Tesla transformer.

    Science.gov (United States)

    Reed, J L

    2015-03-01

    A proof-of-principle Tesla transformer circuit is introduced. The new transformer exhibits the high voltage-high power output signal of shock-excited transformers. The circuit, with specification of proper circuit element values, is capable of obtaining extreme oscillatory voltages. The primary and secondary portions of the circuit communicate solely by conduction. The destructive arcing between the primary and secondary inductors in electromagnetically coupled transformers is ubiquitous. Flashover is eliminated in the new transformer as the high-voltage inductors do not interpenetrate and so do not possess an annular volume of electric field. The inductors are remote from one another. The high voltage secondary inductor is isolated in space, except for a base feed conductor, and obtains earth by its self-capacitance to the surroundings. Governing equations, for the ideal case of no damping, are developed from first principles. Experimental, theoretical, and circuit simulator data are presented for the new transformer. Commercial high-temperature superconductors are discussed as a means to eliminate the counter-intuitive damping due to small primary inductances in both the electromagnetic-coupled and new conduction-coupled transformers.

  16. Wavefield transform of electromagnetic fields

    1994-12-31

    One of the recent developments in electromagnetic (EM) methods for crosshole conductivity imaging involves transformation of diffuse EM fields to wavefields (Lee and Xie, 1993). In this approach the EM fields are first transformed to wavefields. The velocity of the wavefield and the electrical conductivity are related by a simple formula. Using traveltime obtained from the transformed wavefield a ray tomography would be carried out for the wavefield velocity and then the electrical conductivity. From the transformed wavefield only the traveltime is used for the tomographic imaging. This paper examines numerical methods for obtaining travel times by transforming either the time- or the frequency-domain data to wavefields. The number of sample data used for the transform can be as little as ten for the frequency-domain approach and twenty five for the time-domain approach. The accuracy in the traveltime obtained this way seems within one percent provided that the data are sufficiently accurate. The transform originally involves the solution of a Fredholm integral equation of the first kind. Predictably, with lesser amount of data the numerical process becomes more ill-posed.

  17. Integral transformations applied to image encryption

    2017-01-01

    In this paper we consider the application of the integral transformations for image encryption through optical systems, a mathematical algorithm under Matlab platform using fractional Fourier transform (FrFT) and Random Phase Mask (RPM) for digital images encryption is implemented. The FrFT can be related to others integral transforms, such as: Fourier transform, Sine and Cosine transforms, Radial Hilbert transform, fractional Sine transform, fractional Cosine transform, fractional Hartley transform, fractional Wavelet transform and Gyrator transform, among other transforms. The encryption scheme is based on the use of the FrFT, the joint transform correlator and two RPMs, which provide security and robustness to the implemented security system. One of the RPMs used during encryption-decryption and the fractional order of the FrFT are the keys to improve security and make the system more resistant against security attacks.

    The various processes of DNA uptake by cells can be categorized as: viral DNA entry, conjugation, or transformation. Within each category, a variety of mechanisms have been found. However, considerable similarities occur among the different mechanisms of conjugation and, especially, transformation. All of these natural mechanisms of DNA transfer are quite elaborate and involve multiple protein components, as the case may be, of the virus, the donor cell, and the recipient cell. The mechanisms of viral infection and conjugation will be discussed mainly with respect to their relevance to transformation.

    2017-06-01

    The Segal-Bargmann transform is a unitary map between the Schrödinger and Fock space, which is used, for example, to show the integrability of quantum Rabi models. Slice monogenic functions provide the framework in which functional calculus for quaternionic quantum mechanics can be developed. In this paper, a generalisation of the Segal-Bargmann transform, to the context of slice monogenic functions, is constructed and studied in detail. It is shown to interact appropriately with the recently constructed slice Fourier transform. This leads furthermore to a construction of a slice Fock space, which is shown to be a reproducing kernel space.

  4. Transformational leadership in nursing practice.

    Science.gov (United States)

    Doody, Owen; Doody, Catriona M

    Traditionally, nurses have been over-managed and led inadequately, yet today they face unprecedented challenges and opportunities. Organisations constantly face changes that require an increasingly adaptive and flexible leadership. This type of adaptive leadership is referred to as 'transformational'; under it, environments of shared responsibilities that influence new ways of knowing are created. Transformational leadership motivates followers by appealing to higher ideas and moral values, where the leader has a deep set of internal values and ideas. This leads to followers acting to sustain the greater good, rather than their own interests, and supportive environments where responsibility is shared. This article focuses on transformational leadership and its application to nursing through the four components of transformational leadership. These are: idealised influence; inspirational motivation; intellectual stimulation; and individual consideration.

The primary goal of this text is to show how different types of wavelets can be constructed, illustrate why they are such powerful tools in mathematical analysis, and demonstrate their use in applications. It also develops the required analytical knowledge and skills on the part of the reader, rather than focus on the importance of more abstract formulation with full mathematical rigor.  These notes differs from many textbooks with similar titles in that a major emphasis is placed on the thorough development of the underlying theory before introducing applications and modern topics such as fractional Fourier transforms, windowed canonical transforms, fractional wavelet transforms, fast wavelet transforms, spline wavelets, Daubechies wavelets, harmonic wavelets and non-uniform wavelets.

    Dai, Hongzhe; Zheng, Zhibao; Wang, Wei

    2017-03-01

    The fractional Fourier transform (FRFT) is a potent tool to analyze the time-varying signal. However, it fails in locating the fractional Fourier domain (FRFD)-frequency contents which is required in some applications. A novel fractional wavelet transform (FRWT) is proposed to solve this problem. It displays the time and FRFD-frequency information jointly in the time-FRFD-frequency plane. The definition, basic properties, inverse transform and reproducing kernel of the proposed FRWT are considered. It has been shown that an FRWT with proper order corresponds to the classical wavelet transform (WT). The multiresolution analysis (MRA) associated with the developed FRWT, together with the construction of the orthogonal fractional wavelets are also presented. Three applications are discussed: the analysis of signal with time-varying frequency content, the FRFD spectrum estimation of signals that involving noise, and the construction of fractional Harr wavelet. Simulations verify the validity of the proposed FRWT.

  2. Diagnostic Measurements for Power Transformers

    Directory of Open Access Journals (Sweden)

    Stefan Tenbohlen

    2016-05-01

    Full Text Available With the increasing age of the primary equipment of the electrical grids there exists also an increasing need to know its internal condition. For this purpose, off- and online diagnostic methods and systems for power transformers have been developed in recent years. Online monitoring is used continuously during operation and offers possibilities to record the relevant stresses which can affect the lifetime. The evaluation of these data offers the possibility of detecting oncoming faults early. In comparison to this, offline methods require disconnecting the transformer from the electrical grid and are used during planned inspections or when the transformer is already failure suspicious. This contribution presents the status and current trends of different diagnostic techniques of power transformers. It provides significant tutorial elements, backed up by case studies, results and some analysis. The broadness and improvements of the presented diagnostic techniques show that the power transformer is not anymore a black box that does not allow a view into its internal condition. Reliable and accurate condition assessment is possible leading to more efficient maintenance strategies.

    Lamar, J. V.; Merifield, P. M.

    1973-01-01

    One of the photographic techniques which shows great promise as an aid in interpreting ERTS imagery is pseudocolor transformation. It is a process where each shade of gray in an original black-and-white image is seen as a different color in the transformation. The well known ERTS-1 MSS image of the Monterey Bay-San Francisco area was transformed using a technique which requires only two intermediate separations. Possible faults were delineated on an overlay of the transformation before referring to geologic maps. The results were quite remarkable in that all large active or recently active faults shown on the latest geologic map of California were interpreted from the image for all, or much, of their length. Perhaps the most interesting result was the Reliz fault. The fault is shown as covered; however, a lineation corresponding to the position of the fault is visible on the image. The usefulness of ERTS image in identifying recently active faults is demonstrable. Although the faults are also visible in the unenhanced image, they are clearly accentuated and more easily mapped on the pseudocolor transformation.

    1999-02-01

    The work introduces an optical fiber voltage transformer based on the Pockels effect. The transformer is different from a conventional electric-magnetic voltage transformer. A crystal BGO is used as sensor that is sealed in SF6 gas container; the measured signal is transferred by optical fiber in the Electro-Optical Voltage Transformer (EOVT). The principles and composition of EOVT is described here. The system consists of three parts: capacitive divider, optical sensor and electronics module. According to the analysis of factors that influence on the accuracy of measurement, the main ones, temperature and pressure of SF6, are corrected by means of signal digital process. The performances of 110kV EOVT were tested. The results show that the accuracy of EOVT could achieve 0.5 percent. Compared to a conventional electric-magnetic voltage transformer, the advantages of 110kV EOVT are higher accuracy, low cost, small volume, excellent dynamic characteristics and immunity from electromagnetic interference. In particular the low voltage is effectively isolated from the high voltage by means of the optical fiber.

  5. Sensorimotor transformation via sparse coding

    Science.gov (United States)

    Takiyama, Ken

    2015-01-01

    Sensorimotor transformation is indispensable to the accurate motion of the human body in daily life. For instance, when we grasp an object, the distance from our hands to an object needs to be calculated by integrating multisensory inputs, and our motor system needs to appropriately activate the arm and hand muscles to minimize the distance. The sensorimotor transformation is implemented in our neural systems, and recent advances in measurement techniques have revealed an important property of neural systems: a small percentage of neurons exhibits extensive activity while a large percentage shows little activity, i.e., sparse coding. However, we do not yet know the functional role of sparse coding in sensorimotor transformation. In this paper, I show that sparse coding enables complete and robust learning in sensorimotor transformation. In general, if a neural network is trained to maximize the performance on training data, the network shows poor performance on test data. Nevertheless, sparse coding renders compatible the performance of the network on both training and test data. Furthermore, sparse coding can reproduce reported neural activities. Thus, I conclude that sparse coding is necessary and a biologically plausible factor in sensorimotor transformation. PMID:25923980

  6. Efficient transformer for electromagnetic waves

    Science.gov (United States)

    Miller, R.B.

    A transformer structure for efficient transfer of electromagnetic energy from a transmission line to an unmatched load provides voltage multiplication and current division by a predetermined constant. Impedance levels are transformed by the square of that constant. The structure includes a wave splitter, connected to an input transmission device and to a plurality of output transmission devices. The output transmission devices are effectively connected in parallel to the input transmission device. The output transmission devices are effectively series connected to provide energy to a load. The transformer structure is particularly effective in increasing efficiency of energy transfer through an inverting convolute structure by capturing and transferring energy losses from the inverter to the load.

    Sezer, Osman G.; Altunbasak, Yucel

    2009-01-01

    This paper presents a new adaptive Boxcar/Wavelet transform for image compression. Boxcar/Wavelet decomposition emphasizes the idea of average-interpolation representation which uses dyadic averages and their interpolation to explain a special case of biorthogonal wavelet transforms (BWT). This perspective for image compression together with lifting scheme offers the ability to train an optimum 2-D filter set for nonlinear prediction (interpolation) that will adapt to the context around the low-pass wavelet coefficients for reducing energy in the high-pass bands. Moreover, the filters obtained after training is observed to posses directional information with some textural clues that can provide better prediction performance. This work addresses a firrst step towards obtaining this new set of training-based fillters in the context of Boxcar/Wavelet transform. Initial experimental results show better subjective quality performance compared to popular 9/7-tap and 5/3-tap BWTs with comparable results in objective quality.

    2017-02-01

    Despite substantial focus on sustainability issues in both science and politics, humanity remains on largely unsustainable development trajectories. Partly, this is due to the failure of sustainability science to engage with the root causes of unsustainability. Drawing on ideas by Donella Meadows, we argue that many sustainability interventions target highly tangible, but essentially weak, leverage points (i.e. using interventions that are easy, but have limited potential for transformational change). Thus, there is an urgent need to focus on less obvious but potentially far more powerful areas of intervention. We propose a research agenda inspired by systems thinking that focuses on transformational 'sustainability interventions', centred on three realms of leverage: reconnecting people to nature, restructuring institutions and rethinking how knowledge is created and used in pursuit of sustainability. The notion of leverage points has the potential to act as a boundary object for genuinely transformational sustainability science.

    Fischer, Shelly Ann

    2017-08-16

    Healthcare is a complex area with significant potential for service improvement despite the effects of increasing economic and social pressures on the quality and safety of patient care. As the largest group of healthcare professionals in direct contact with patients, nurses are well positioned to contribute to improvements in healthcare services and to the development of new policies. To influence healthcare improvements and policies effectively, nurses require leadership skills. Historically, it was thought that only nurses in management roles required leadership skills; however, the ability to influence change is a requirement at all levels of clinical practice. Transformational leadership competencies provide nurses with the skills to contribute to improvements in the quality and safety of patient care, while enhancing their career satisfaction. This article examines how nurses can apply transformational leadership to their practice. It also informs nurses how to conduct an initial self-assessment of their leadership skills and to formulate a transformational leadership development plan.

  11. Transformational Leadership and Team Performance

    Huey-Wen Chou

    2013-07-01

    Full Text Available This study explores the relationships among transformational leadership style, cognitive trust, and collective efficacy as well as the impact of these variables on distal team performance. Data collected from 39 teams find that team cognitive trust as two process variables involves a transformational leadership process in which cognitive trust in the team leader and cognitive trust among team members mediate the impact of this leadership style on collective efficacy. Unlike previous studies, our results show that leveraging cognitive trust in the team leader is necessary but not sufficient for better proximal collective efficacy, which in turn facilitates distal team performance. Although cognitive trust among team members was more closely related to proximal collective efficacy than cognitive trust in the team leader was, the factors that foster the development of cognitive trust among team members remain scantly explored in the transformational leadership literature and deserve more attention in future research.

    Full Text Available The article is aimed at defining the questions, giving answers to which is necessary for scientific substantiation of the tax transformation in Ukraine. The article analyzes the structural-logical relationships of the theories, providing substantiation of tax systems and transformation of them. Various views on the level of both the tax burden and the distribution of the tax burden between big and small business have been systematized. The issues that require theoretical substantiation when choosing a model of tax system have been identified. It is determined that shares of both indirect and direct taxes and their rates can be substantiated by calculations on the basis of statistical data. The results of the presented research can be used to develop the algorithm for theoretical substantiation of tax transformation

    Full Text Available The main purpose of this paper was to carry out an empirical research on whether transformational leadership, in comparison to other contemporary leadership styles, contributes to higher employee satisfaction levels. In total, 399 respondents took part in this research, which was conducted in companies in Bosnia and Herzegovina and Germany. This was the starting point to identify the dominant leadership style in each of the two countries. Using a nonparametric Mann-Whitney test, it was proved that there is a statistically significant difference in employee satisfaction under transformational leadership as opposed to the transactional and charismatic styles. After a detailed research of the literature, it became apparent that research on this subject is scarce. Accordingly, presenting transformational leadership and its influence on employee satisfaction was a particular challenge.

  16. Transformative Theory in Social Research

    DEFF Research Database (Denmark)

    Ravn, Ib

    Social-scientific theory usually represents an attempt to describe or explain social phenomena and, sometimes, to criticize them. However, a theory can be transformative in the sense that in using and testing it, researchers may help practitioners transform and improve their social conditions......, institutions or organisations. This idea is illustrated by a research-and-development effort to help conference organisers develop meeting formats that create more learning among delegates than is accomplished by the conventional, lecture-based format. This effort was based on a (transformative) theory...... it from the good intentions harboured by all change agents include theoretical grounding, a coherent ontology, testable hypotheses, systematic evaluation, external validity and theory-action consistency....

  18. Disformal transformations on the CMB

    CERN Document Server

    Burrage, Clare; Davis, Anne-Christine

    2016-01-01

    In this work we study the role of disformal transformation on cosmological backgrounds and its relation to the speed of sound for tensor modes. A speed different from one for tensor modes can arise in several contexts, such as Galileons theories or massive gravity, nevertheless the speed is very constrained to be one by observations of gravitational wave emission. It has been shown that in inflation a disformal trans- formation allows to set the speed for tensor modes to one without making changes to the curvature power spectrum. Here we show that this invariance does not hold when considering the CMB anisotropy power spectrum. It turns out that the after doing the transformation there is an imprint on the acoustic peaks and the diffusion damping. This has interesting consequences; here we explore quartic galileon theories which allow a modified speed for tensor modes. For these theories the transformation can be used to constraint the parameter space in different regimes.

    In this second part, the most important components of a magnetooptical current transformer are described and their suitability is discussed. Today He-Ne gas lasers and laser diodes seem to meet best the requirements of the light source. Single-mode optical fibers are capable of transmitting polarized light without depolarization. A fiber coil wound on a special coil former is used as a measuring sensor. Two P-I-N photodiodes, together with an analog electronic circuit, transform the optical into an electrical measuring signal.

    2016-01-20

    Instrument current transformers (CTs) measure AC currents. The DC component in the measured current can saturate the transformer and cause gross error. We use fluxgate detection and digital feedback compensation of the DC flux to suppress the overall error to 0.15%. This concept can be used not only for high-end CTs with a nanocrystalline core, but it also works for low-cost CTs with FeSi cores. The method described here allows simultaneous measurements of the DC current component.

    2016-06-01

    Electromagnetism, the strong and the weak interactions are commonly formulated as gauge theories in a Lagrangian description. In this paper, we present an alternative formal derivation of U(1)-gauge theory in a manifestly covariant Hamilton formalism. We make use of canonical transformations as our guiding tool to formalize the gauging procedure. The introduction of the gauge field, its transformation behavior and a dynamical gauge field Lagrangian/Hamiltonian are unavoidable consequences of this formalism, whereas the form of the free gauge Lagrangian/Hamiltonian depends on the selection of the gauge dependence of the canonically conjugate gauge fields.

  4. Development of Toroidal Core Transformers

    Energy Technology Data Exchange (ETDEWEB)

    de Leon, Francisco [New York Univ. (NYU), Brooklyn, NY (United States). Dept. of Electrical and Computer Engineering

    2014-08-01

    The original objective of this project was to design, build and test a few prototypes of single-phase dry-type distribution transformers of 25 kVA, 2.4 kV primary to 120 V transformers using cores made of a continuous steel strip shaped like a doughnut (toroid). At different points during the development of the project, the scope was enhanced to include the more practical case of a 25 kVA transformer for a 13.8 kV primary system voltage. Later, the scope was further expanded to design and build a 50 kVA unit to transformer voltage from 7.62 kV to 2x120 V. This is a common transformer used by Con Edison of New York and they are willing to test it in the field. The project officially started in September 2009 and ended in May 2014. The progress was reported periodically to DOE in eighteen quarterly reports. A Continuation Application was submitted to DOE in June 2010. In May 2011 we have requested a non-cost extension of the project. In December 2011, the Statement of Project Objectives (SOPO) was updated to reflect the real conditions and situation of the project as of 2011. A second Continuation Application was made and funding was approved in 2013 by DOE and the end date was extended to May 2014. The technical challenges that were overcome in this project include: the development of the technology to pass the impulse tests, derive a model for the thermal performance, produce a sound mechanical design, and estimate the inrush current. However, the greatest challenge that we faced during the development of the project was the complications of procuring the necessary parts and materials to build the transformers. The actual manufacturing process is relatively fast, but getting all parts together is a very lengthy process. The main products of this project are two prototypes of toroidal distribution transformers of 7.62 kV (to be used in a 13.8 kV system) to 2x120 V secondary (standard utilization voltage); one is rated at 25 kVA and the other at 50 kVA.

    The disposal of red mud, which is a solid waste that is generated during the extraction of alumina from bauxite, is one of major problems faced by the aluminum industry. Alkali in red mud seeping under the soil may pollute land and water. The Northeastern University, China, has proposed a calcification-carbonation method to deal with low-grade bauxite or red mud. Its main purpose is to change the equilibrium phase of red mud to 2CaO·SiO2 and CaCO3 hydrometallurgically, so that recomposed alkali-free red mud can be widely used. We conducted calcification transformation experiments using diasporic bauxite sampled from Wenshan, and investigated the effects of parameters such as diasporic bauxite grain size, temperature and treatment time on the calcification transformation digestion rate, which is also termed the calcification transformation rate (CTR). The main phase in the calcification transformation slag (CTS) is hydrogarnet with different grain sizes. The CTR increases with decrease in diasporic bauxite grain size, or increase in temperature or reaction time. The CTR reaches a maximum of 87% after 120 min reaction at 240°C. The Na2O/Al2O3 ratio decreases with increase in temperature and reaches 1.5. The sodium content in the CTS decreases with increasing reaction time and is lower than that in the red mud treated using the Bayer process (4-12%).

  9. Transformation pipelines for PROJ.4

    Knudsen, Thomas; Evers, Kristian

    2017-04-01

    For more than 2 decades, PROJ.4 has been the globally leading map projection library for open source (and probably also closed source) geospatial software. While focusing on mathematically well defined 2D projections from geographical to planar coordinates, PROJ.4 has nevertheless, since its introduction in the 1980s, provided limited support for more general geodetic datum transformations, and has gradually introduced a higher degree of support for 3D coordinate data and reference systems. The support has, however, been implemented over a long period of time, as need became evident and opportunity was found, by a number of different people, with different needs and at different times. Hence, the PROJ.4 3D support has not been the result of neither deep geodetic, nor careful code architectural considerations. This has resulted in a library that supports only a subset of commonly occurring geodetic transformations. To be more specific: It supports any datum shift that can be completed by a combination of two Helmert shifts (to and from a pivot datum) and, potentially, also a non-linear planar correction derived from interpolation in a correction grid. While this is sufficient for most small scale mapping activities, it is not at all sufficient for operational geodetic use, nor for many of the rapidly emerging high accuracy geospatial applications in agriculture, construction, transportation and utilities. To improve this situation, we have introduced a new framework for implementation of geodetic transformations, which will appear in the next release of the PROJ.4 library. Before describing the details, let us first remark that most cases of geodetic transformations can be expressed as a series of elementary operations, the output of one operation being the input of the next. E.g. when going from UTM zone 32, datum ED50, to UTM zone 32, datum ETRS89, one must, in the simplest case, go through 5 steps: Back-project the UTM coordinates to geographic coordinates

  1. Equivalent configurations of optical transformation media.

    Science.gov (United States)

    Chen, Tungyang; Cheng, Shen-Wen; Weng, Chung-Ning

    2009-11-09

    We demonstrate that a medium consisting of two adjoining distinct layers of transformation materials, corresponding respectively to two linear coordinate transformations, can behave effectively as that of the same region transformed by another linear transformation. The equivalence means that, irrespective of the direction of incident wave, the fields of the medium exterior to the transformed regions of the two configurations are exactly the same. This property can also apply to a domain that is transformed by a piecewise linear transformation function, and to a medium that is mapped by a general curved function. This proof is shown analytically based on a rigorous Fourier-Bessel analysis. The equivalence suggests that, for a given transformed domain, one can find an infinite number of complementary media that altogether can give a desired effective response of certain transformation path.

  2. Magnetic bead detection using nano-transformers.

    Science.gov (United States)

    Kim, Hyung Kwon; Hwang, Jong Seung; Hwang, Sung Woo; Ahn, Doyeol

    2010-11-19

    A novel scheme to detect magnetic beads using a nano-scale transformer with a femtoweber resolution is reported. We have performed a Faraday's induction experiment with the nano-transformer at room temperature. The transformer shows the linear output voltage responses to the sinusoidal input current. When magnetic beads are placed on the transformer, the output responses are increased by an amount corresponding to the added magnetic flux from the beads when compared with the case of no beads on the transformer. In this way, we could determine whether magnetic beads are on top of the transformer in a single particle level.

  3. Metamaterial-enabled transformation optics

    Science.gov (United States)

    Landy, Nathan

    Transformation Optics is a design methodology that uses the form invariance of Maxwell's equations to distort electromagnetic fields. This distortion is imposed on a region of space by mimicking a curvilinear coordinate system with prescribed magnetoelectric material parameters. By simply specifying the correct coordinate transformation, researchers have created such exotic devices as invisibility cloaks, ``perfect'' lenses, and illusion devices. Unfortunately, these devices typically require correspondingly exotic material parameters that do not occur in Nature. Researchers have therefore turned to complex artificial media known as metamaterials to approximate the desired responses. However, the metamaterial design process is complex, and there are limitations on the responses that they achieve. In this dissertation, we explore both the applicability and limitations of metamaterials in Transformation Optics design. We begin in Chapter 2 by investigating the freedoms available to use in the transformation optics design process itself. We show that quasi-conformal mappings may be used to alleviate some of the complexity of material design in both two- and three-dimensional design. We then go on in Chapter 3 to apply this method to the design of a transformation-optics modified optic. We show that even a highly-approximate implementation of such a lens would retain many of the key performance feautures that we would expect from a full material prescription. However, the approximations made in the design of our lens may not be valid in other areas of transformation optical design. For instance, the high-frequency approximations of our lens design ignore the effects of impedance mismatch, and the approximation is not valid when the material parameters vary on the order of a wavelength. Therefore, in Chapter 4 we use other freedoms available to us to design a full-parameter cloak of invisibility. By tailoring the electromagnetic environment of our cloak, we are able to

  4. Transformations of triangle ladder diagrams

    Science.gov (United States)

    Kondrashuk, Igor; Vergara, Alvaro

    2010-03-01

    It is shown how dual space diagrammatic representation of momentum integrals corresponding to triangle ladder diagrams with an arbitrary number of rungs can be transformed to half-diamonds. In paper arXiv:0803.3420 [hep-th] the half-diamonds were related by conformal integral substitution to the diamonds which represent the dual space image of four-point ladder integrals in the four-dimensional momentum space. Acting in the way described in the present paper we do not need to use the known result for diamond (four-point) diagrams as an external input in deriving relations of arXiv:0803.3420 [hep-th], however, that result for the diamond diagram arises in the present proof as an intermediate consequence in a step-by-step diagrammatic transformation from the triangle ladder diagram to the half-diamond diagrams.

  7. Isotropic transformation acoustics and applications

    Science.gov (United States)

    Su, Xiaoshi; Norris, Andrew N.

    2017-04-01

    A novel class of acoustic metamaterial is proposed for directional collimation of a cylindrical source into a plane wave beam. The effect is based on transformation acoustics which retains the exact form of the wave equation under conformal mapping from a circular region to a triangular area. The transformation is adjustable, allowing the acoustic energy to be equally radiated in three directions, or preferentially in a single direction. Importantly, the material properties in the physical domain are isotropic and therefore practically realizable. Two example devices are proposed using cylindrical elastic shells in water as the metamaterial elements and demonstrated using full wave simulations. This approach has potential applications beyond acoustic antenna design in beam-steering and wavefront manipulation.

  8. Good Governance, Welfare, and Transformation

    Directory of Open Access Journals (Sweden)

    Hans-Jürgen Wagener

    2004-06-01

    Full Text Available Market conforming institutions are a precondition for a thriving and stable economy. This is the upshot of the Washington consensus or, of somewhat earlier origin, the “Eucken hypothesis”. Another hypothesis of Eucken has it that market conforming institutions are the product of a strong state. However, more general and more important than the strong state is good governance. In this paper I refer to it as the “Lorenzetti hypothesis”. The paper tries to figure out the mechanisms by which good governance and economic order influence economic outcome. Then the two hypotheses are tested for two aspects of economic outcome: productivity as measured by GNP per capita over a wide range of countries and transformation success as measured by GNP growth over the European transformation countries. The tests confirm the theoretical expectation that good governance is more important than good order

  10. Natural transformation in Acinetobacter calcoaceticus.

    Science.gov (United States)

    Shanley, M S; Ahmadian-Tehrani, M; Benjamin, R C; Leher, H F

    1990-01-01

    Acinetobacter calcoaceticus is a metabolically versatile microorganism that is naturally competent for DNA uptake and incorporation. We have exploited the natural state of competency for studies involving the cloning, organization and expression of genes encoding catabolic enzymes. A. calcoaceticus is able to take up, at high efficiency, genetically engineered DNA, incorporate the DNA and stably maintain and express the DNA. Sequence analysis of cloned A. calcoaceticus DNA reveals a great deal of internal repetition and secondary structure, but no specific sequences associated with uptake appear to be present. Uptake and transformation occurs in solid and liquid medium, at a wide range of DNA concentrations and with little restriction barrier to the source of the transforming DNA.

    Full Text Available Carry Value Transformation (CVT is a model of discrete deterministic dynamical system. In the present study, it has been proved that (1 the sum of any two nonnegative integers is the same as the sum of their CVT and XOR values. (2 the number of iterations leading to either CVT=0 or XOR=0 does not exceed the maximum of the lengths of the two addenda expressed as binary strings. A similar process of addition of modified Carry Value Transformation (MCVT and XOR requires a maximum of two iterations for MCVT to be zero. (3 an equivalence relation is shown to exist on Z×Z which divides the CV table into disjoint equivalence classes.

  12. Transformational leadership and moral reasoning.

    Turner, Nick; Barling, Julian; Epitropaki, Olga; Butcher, Vicky; Milner, Caroline

    2002-04-01

    Terms such as moral and ethical leadership are used widely in theory, yet little systematic research has related a sociomoral dimension to leadership in organizations. This study investigated whether managers' moral reasoning (n = 132) was associated with the transformational and transactional leadership behaviors they exhibited as perceived by their subordinates (n = 407). Managers completed the Defining Issues Test (J. R. Rest, 1990), whereas their subordinates completed the Multifactor Leadership Questionnaire (B. M. Bass & B. J. Avolio, 1995). Analysis of covariance indicated that managers scoring in the highest group of the moral-reasoning distribution exhibited more transformational leadership behaviors than leaders scoring in the lowest group. As expected, there was no relationship between moral-reasoning group and transactional leadership behaviors. Implications for leadership development are discussed.

    The design, fabrication, and initial characterization of a miniature single-pass Fourier-transform spectrometer (FTS) that has an optical bench that measures 1 cm x 5 cm x 10 cm is presented. The FTS is predicated on the classic Michelson interferometer design with a moving mirror. Precision translation of the mirror is accomplished by microfabrication of dovetailed bearing surfaces along single-crystal planes in silicon. Although it is miniaturized, the FTS maintains a relatively high spectral resolution, 0.1 cm-1, with adequate optical throughput.

    We present synthetic Fourier transform light scattering, a method for measuring extended angle-resolved light scattering (ARLS) from individual microscopic samples. By measuring the light fields scattered from the sample plane and numerically synthesizing them in Fourier space, the angle range of the ARLS patterns is extended up to twice the numerical aperture of the imaging system with unprecedented sensitivity and precision. Extended ARLS patterns of individual microscopic polystyrene beads, healthy human red blood cells (RBCs), and Plasmodium falciparum-parasitized RBCs are presented.

    It is shown how dual space diagrammatic representation of momentum integrals corresponding to triangle ladder diagrams with an arbitrary number of rungs can be transformed to half-diamonds. In paper arXiv:0803.3420 [hep-th] the half-diamonds were related by conformal integral substitution to the diamonds which represent the dual space image of four-point ladder integrals in the four-dimensional momentum space. Acting in the way described in the present paper we do not need to use the known re...

  3. Graph Creation, Visualisation and Transformation

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available We describe a tool to create, edit, visualise and compute with interaction nets - a form of graph rewriting systems. The editor, called GraphPaper, allows users to create and edit graphs and their transformation rules using an intuitive user interface. The editor uses the functionalities of the TULIP system, which gives us access to a wealth of visualisation algorithms. Interaction nets are not only a formalism for the specification of graphs, but also a rewrite-based computation model. We discuss graph rewriting strategies and a language to express them in order to perform strategic interaction net rewriting.

    2006-03-01

    The quality of trial wave-functions, and of their nodal surface in particular, determines the accuracy of the results obtained within the Fixed-Node Diffusion Monte Carlo (DMC) method. Backflow transformations have been proven capable of improving the nodal surface of Slater-Jastrow (SJ) wave-functions in homogeneous systems. In this work we will present the extension of backflow to inhomogeneous systems, along with DMC results for atoms, molecules and solids which show the improved accuracy of this form of trial wave-function. We will also discuss the advantages of using electron-by-electron algorithms to enhance the computational efficiency of QMC with backflow wave-functions.

    Kaplan, Simon G.; Quijada, Manuel A.

    2015-01-01

    This chapter describes the use of Fourier transform spectrometers (FTS) for accurate spectrophotometry over a wide spectral range. After a brief exposition of the basic concepts of FTS operation, we discuss instrument designs and their advantages and disadvantages relative to dispersive spectrometers. We then examine how common sources of error in spectrophotometry manifest themselves when using an FTS and ways to reduce the magnitude of these errors. Examples are given of applications to both basic and derived spectrophotometric quantities. Finally, we give recommendations for choosing the right instrument for a specific application, and how to ensure the accuracy of the measurement results..

    2013-01-01

    Biodefense vaccines are developed against a diverse group of pathogens. Vaccines were developed for some of these pathogens a long time ago but they are facing new challenges to move beyond the old manufacturing technologies. New vaccines to be developed against other pathogens have to determine whether to follow traditional vaccination strategies or to seek new approaches. Advances in basic immunology and recombinant DNA technology have fundamentally transformed the process of formulating a vaccine concept, optimizing protective antigens, and selecting the most effective vaccine delivery approach for candidate biodefense vaccines.

    2008-01-01

    A study group on Conceptualizing Transformation in Child and Adult Analysis focused on a particular kind of change in analysis, that of transformational change, a change in organization that could not be predicted from what came before. We found that, based on careful presentations of four analytic cases, transformational or pre-transformational change did take place. A central intervening variable was the patient's development of a sense of agency. We tried to articulate the nature of the interventions leading to agency and ultimately to transformation. We added other new dimensions: an emphasis on construction in addition to reconstruction and a focus on the future.

    This paper presents a broadband Guanella-type planar impedance transformer that transforms so 50 omega to 10 omega with a 10 dB bandwidth of 1-14GHz. The transformer is designed on a flexible 50 micrometer thick polyimide substrate in microstrip and parallel-plate transmission line topologies, and is Inspired by the traditional 4:1 Guanella transformer. Back-to-back transformers were designed and fabricated for characterization in a 50 omega system. Simulated and measured results are in excellent agreement.

    The possibility of 3D printing a transformer core using fused deposition modeling methods is explored. With the use of additive manufacturing, ideal transformer core geometries can be achieved in order to produce a more efficient transformer. In this work, different 3D printed settings and toroidal geometries are tested using a custom integrated magnetic circuit capable of measuring the hysteresis loop of a transformer. These different properties are then characterized, and it was determined the most effective 3D printed transformer core requires a high fill factor along with a high concentration of magnetic particulate.

    1994-04-01

    It is common practice to install only phase to ground surge arresters for transformer insulation protection against electrical stresses. However, this may not adequately protect the delta connected transformer phase to phase winding insulation. High phase to phase overvoltages at the transformer terminals, due to capacitor switching, have been reported. This paper describes the excessive phase to phase overvoltages that can also occur due to wave propagation and surge transfer through transformers. This paper points out the need for surge arrester arrangements that protect both, phase to phase and phase to ground transformer insulations. Surge arrester arrangements, selection criteria, installation practices, and application considerations are discussed in this paper.

  16. Performance Comparison and Selection of Transformer Fluid

    Directory of Open Access Journals (Sweden)

    Lu Yang

    2016-01-01

    Full Text Available Transformer fluid directly affects the working state of the components and the cooling efficiency of transformer. There are three kinds of transformer fluid used for electric locomotive, EMU and suburban rail vehicles: mineral oil, silicone liquid and synthetic ester based insulating oil. In this paper, the three kinds of oil are compared from the fire safety, environmental protection, reliability and low maintenance. It provides a strong basis for the selection of transformer fluid. By comprehensive analysis, synthetic ester based insulating oil can completely replace mineral oil and silicone liquid. With rail transport safety and environmental protection standards improving, synthetic ester based insulating oil will be the best choice for transformer.

  17. Computing Instantaneous Frequency by normalizing Hilbert Transform

    Science.gov (United States)

    Huang, Norden E. (Inventor)

    2005-01-01

    This invention presents Normalized Amplitude Hilbert Transform (NAHT) and Normalized Hilbert Transform(NHT), both of which are new methods for computing Instantaneous Frequency. This method is designed specifically to circumvent the limitation set by the Bedorsian and Nuttal Theorems, and to provide a sharp local measure of error when the quadrature and the Hilbert Transform do not agree. Motivation for this method is that straightforward application of the Hilbert Transform followed by taking the derivative of the phase-angle as the Instantaneous Frequency (IF) leads to a common mistake made up to this date. In order to make the Hilbert Transform method work, the data has to obey certain restrictions.

    Fischer, Shelly A

    2016-11-01

    To analyse the concept of transformational leadership in the nursing context. Tasked with improving patient outcomes while decreasing the cost of care provision, nurses need strategies for implementing reform in health care and one promising strategy is transformational leadership. Exploration and greater understanding of transformational leadership and the potential it holds is integral to performance improvement and patient safety. Concept analysis using Walker and Avant's (2005) concept analysis method. PubMed, CINAHL and PsychINFO. This report draws on extant literature on transformational leadership, management, and nursing to effectively analyze the concept of transformational leadership in the nursing context. This report proposes a new operational definition for transformational leadership and identifies model cases and defining attributes that are specific to the nursing context. The influence of transformational leadership on organizational culture and patient outcomes is evident. Of particular interest is the finding that transformational leadership can be defined as a set of teachable competencies. However, the mechanism by which transformational leadership influences patient outcomes remains unclear. Transformational leadership in nursing has been associated with high-performing teams and improved patient care, but rarely has it been considered as a set of competencies that can be taught. Also, further research is warranted to strengthen empirical referents; this can be done by improving the operational definition, reducing ambiguity in key constructs and exploring the specific mechanisms by which transformational leadership influences healthcare outcomes to validate subscale measures. © 2016 John Wiley & Sons Ltd.

  20. Box-Cox transformation for QTL mapping.

    Science.gov (United States)

    Yang, Runqing; Yi, Nengjun; Xu, Shizhong

    2006-01-01

    The maximum likelihood method of QTL mapping assumes that the phenotypic values of a quantitative trait follow a normal distribution. If the assumption is violated, some forms of transformation should be taken to make the assumption approximately true. The Box-Cox transformation is a general transformation method which can be applied to many different types of data. The flexibility of the Box-Cox transformation is due to a variable, called transformation factor, appearing in the Box-Cox formula. We developed a maximum likelihood method that treats the transformation factor as an unknown parameter, which is estimated from the data simultaneously along with the QTL parameters. The method makes an objective choice of data transformation and thus can be applied to QTL analysis for many different types of data. Simulation studies show that (1) Box-Cox transformation can substantially increase the power of QTL detection; (2) Box-Cox transformation can replace some specialized transformation methods that are commonly used in QTL mapping; and (3) applying the Box-Cox transformation to data already normally distributed does not harm the result.

  1. Model Validation in Ontology Based Transformations

    Directory of Open Access Journals (Sweden)

    Jesús M. Almendros-Jiménez

    2012-10-01

    Full Text Available Model Driven Engineering (MDE is an emerging approach of software engineering. MDE emphasizes the construction of models from which the implementation should be derived by applying model transformations. The Ontology Definition Meta-model (ODM has been proposed as a profile for UML models of the Web Ontology Language (OWL. In this context, transformations of UML models can be mapped into ODM/OWL transformations. On the other hand, model validation is a crucial task in model transformation. Meta-modeling permits to give a syntactic structure to source and target models. However, semantic requirements have to be imposed on source and target models. A given transformation will be sound when source and target models fulfill the syntactic and semantic requirements. In this paper, we present an approach for model validation in ODM based transformations. Adopting a logic programming based transformational approach we will show how it is possible to transform and validate models. Properties to be validated range from structural and semantic requirements of models (pre and post conditions to properties of the transformation (invariants. The approach has been applied to a well-known example of model transformation: the Entity-Relationship (ER to Relational Model (RM transformation.

    Birchenall, C. E.

    1980-01-01

    The feasibility of using metal alloys as thermal energy storage media was investigated. The elements selected as candidate media were limited to aluminum, copper, magnesium, silicon, zinc, calcium, and phosphorus on the basis of low cost and latent heat of transformation. Several new eutectic alloys and ternary intermetallic phases were determined. A new method employing X-ray absorption techniques was developed to determine the coefficients of thermal expansion of both the solid and liquid phases and the volume change during phase transformation. The method and apparatus are discussed and the experimental results are presented for aluminum and two aluminum-eutectic alloys. Candidate materials were evaluated to determine suitable materials for containment of the metal alloys. Graphite was used to contain the alloys during the volume change measurements. Silicon carbide was identified as a promising containment material and surface-coated iron alloys were also evaluated. System considerations that are pertinent if alloy eutectics are used as thermal energy storage media are discussed. Potential applications to solar receivers and industrial furnaces are illustrated schematically.

  3. Transformational III-V Electronics

    KAUST Repository

    Nour, Maha A.

    2014-04-01

    Flexible electronics using III-V materials for nano-electronics with high electron mobility and optoelectronics with direct band gap are attractive for many applications. This thesis describes a complementary metal oxide semiconductor (CMOS) compatible process for transforming traditional III-V materials based electronics into flexible one. The thesis reports releasing 200 nm of Gallium Arsenide (GaAs) from 200 nm GaAs / 300 nm Aluminum Arsenide (AlAs) stack on GaAs substrate using diluted hydrofluoric acid (HF). This process enables releasing a single top layer compared to peeling off all layers with small sizes at the same time. This is done utilizing a network of release holes that contributes to the better transparency (45 % at 724 nm wavelengths) observed. Fabrication of metal oxide semiconductor capacitor (MOSCAPs) on GaAs is followed by releasing it to have devices on flexible 200 nm GaAs. Similarly, flexible GaSb and InP fabrication process is also reported to transform traditional electronics into large-area flexible electronics.

  4. The Transformed Function of Parliamentarism

    Directory of Open Access Journals (Sweden)

    Davor Rodin

    2005-01-01

    Full Text Available The author deals with the transformation of the role of parliamentarism in modern democratic countries. Drawing on the views of Carl Schmitt, the author argues that the parliament as a political institution is in a crisis because its decisions are based on the will of the party or coalition in power rather than on the most pertinent arguments. Therefore, the author suggests that there is a crisis of parliamentarism, which he, referring to Schmitt, assesses as a rejection of argumentative parliamentary democracy to the advantage of a democracy characterised by a confl ict of various party interests. According to the author, this implies that parliament members represent the interests of their parties, to which they are directly responsible, and no longer the people, as summarised by Niklas Luhmann’s assessment that “parties have disempowered their members of parliament”. In the second part of the paper, the author discusses the transformation of the legislative function of parliaments. In doing so, he follows the normative view that the parliament must fall back to the framework of its political function and reassess its position as exclusive legislator. In the author’s opinion, the problem is that its legislative monopoly makes it immune to extraparliamentary and judicial legislative initiatives.

  5. Digitally compensated beam current transformer

    CERN Document Server

    Kesselman, Martin

    2005-01-01

    The Spallation Neutron Source (SNS) is being built by a collaboration of six laboratories. Beam current monitors (BCMs) will be used to record the current of H-minus and H-plus beams ranging from 15 mA (tune-up in the Front End and Linac) to over 60A fully accumulated in the Ring and dumped to the load as a single pulse in the Ring to Beam Target (RTBT). The time structure of these beams ranges from 645ns "mini" bunches at the 1.05 MHz ring revolution rate, to an overall 1 ms long macro-pulse. The requirements for the BCMs will depend upon their location within the system. The need to measure individual mini-pulses, examine the characteristics of the chopper edge, as well as the longer average current pulse of the macropulse, or long duration pulses during Linac tuning place wide requirements upon the response of current transformers. To obtain the desired accuracy and resolution, current transformers must have less than 1 ns rise time and droops of 0.1 %/ms. This places a significant design burden on the cur...

  6. Conformal Gauge Transformations in Thermodynamics

    Directory of Open Access Journals (Sweden)

    Alessandro Bravetti

    2015-09-01

    Full Text Available In this work, we show that the thermodynamic phase space is naturally endowed with a non-integrable connection, defined by all of those processes that annihilate the Gibbs one-form, i.e., reversible processes. We argue that such a connection is invariant under re-scalings of the connection one-form, whilst, as a consequence of the non-integrability of the connection, its curvature is not and, therefore, neither is the associated pseudo-Riemannian geometry. We claim that this is not surprising, since these two objects are associated with irreversible processes. Moreover, we provide the explicit form in which all of the elements of the geometric structure of the thermodynamic phase space change under a re-scaling of the connection one-form. We call this transformation of the geometric structure a conformal gauge transformation. As an example, we revisit the change of the thermodynamic representation and consider the resulting change between the two metrics on the thermodynamic phase space, which induce Weinhold’s energy metric and Ruppeiner’s entropy metric. As a by-product, we obtain a proof of the well-known conformal relation between Weinhold’s and Ruppeiner’s metrics along the equilibrium directions. Finally, we find interesting properties of the almost para-contact structure and of its eigenvectors, which may be of physical interest.

  7. Discrete frequency slice wavelet transform

    Science.gov (United States)

    Yan, Zhonghong; Tao, Ting; Jiang, Zhongwei; Wang, Haibin

    2017-11-01

    This paper introduces a new kind of Time-Frequency Representation (TFR) method called Discrete Frequency Slice Wavelet Transform (DFSWT). It is an improved version of Frequency Slice Wavelet Transform (FSWT). The previous researches on FSWT show that it is a new efficient TFR in an easy way without strict limitation as traditional wavelet theory. DFSWT as well as FSWT are defined directly in frequency domain, and still keep its properties in time-frequency domain as FSWT decomposition, reconstruction and filter design, etc. However, the original signal is decomposed and reconstructed on a Chosen Frequency Domains (CFD) as need of application. CFD means that the decomposition and reconstruction are not completed on all frequency components. At first, it is important to discuss the necessary condition of CFD to reconstruct the original signal. And then based on norm l2, an optimization algorithm is introduced to reconstruct the original signal even accurately. Finally, for a test example, the TFR analysis of a real life signal is shown. Some conclusions are drawn that the concept of CFD is very useful to application, and the DFSWT can become a simple and easy tool of TFR method, and also provide a new idea of low speed sampling of high frequency signal in applications.

    2014-01-01

    Full Text Available Follicular lymphoma (FL is an indolent disease, but 30%–40% of cases undergo histologic transformation to an aggressive malignancy, typically represented by diffuse large B cell lymphoma (DLBCL. The pathogenesis of this process remains largely unknown. Using whole-exome sequencing and copy-number analysis, we show here that the dominant clone of FL and transformed FL (tFL arise by divergent evolution from a common mutated precursor through the acquisition of distinct genetic events. Mutations in epigenetic modifiers and antiapoptotic genes are introduced early in the common precursor, whereas tFL is specifically associated with alterations deregulating cell-cycle progression and DNA damage responses (CDKN2A/B, MYC, and TP53 as well as aberrant somatic hypermutation. The genomic profile of tFL shares similarities with that of germinal center B cell-type de novo DLBCL but also displays unique combinations of altered genes with diagnostic and therapeutic implications.

  9. Supersymmetric Transformations in Optical Fibers

    Science.gov (United States)

    Macho, Andrés; Llorente, Roberto; García-Meca, Carlos

    2018-01-01

    Supersymmetry (SUSY) has recently emerged as a tool to design unique optical structures with degenerate spectra. Here, we study several fundamental aspects and variants of one-dimensional SUSY in axially symmetric optical media, including their basic spectral features and the conditions for degeneracy breaking. Surprisingly, we find that the SUSY degeneracy theorem is partially (totally) violated in optical systems connected by isospectral (broken) SUSY transformations due to a degradation of the paraxial approximation. In addition, we show that isospectral constructions provide a dimension-independent design control over the group delay in SUSY fibers. Moreover, we find that the studied unbroken and isospectral SUSY transformations allow us to generate refractive-index superpartners with an extremely large phase-matching bandwidth spanning the S +C +L optical bands. These singular features define a class of optical fibers with a number of potential applications. To illustrate this, we numerically demonstrate the possibility of building photonic lanterns supporting broadband heterogeneous supermodes with large effective area, a broadband all-fiber true-mode (de)multiplexer requiring no mode conversion, and different mode-filtering, mode-conversion, and pulse-shaping devices. Finally, we discuss the possibility of extrapolating our results to acoustics and quantum mechanics.

    Science.gov (United States)

    Young-Mason, J; Mastrangelo, M

    1997-09-01

    In "The Soft Core" Arturo Vivante examines the bonds between a middle-aged son and his aging father. Years of habit that had solidified into accustomed but uncomfortable ways of behaving and interacting with each other are altered when the father's stroke evokes a tumultuous range of emotions in the son, leading him, in the end, to feel compassion, not just for his father but also for himself. Vivante shows the reader that illness has the ability to transform an individual who is willing to reexamine and reevaluate the meaning he or she gives to life. This process, however, is not an easy one, as it is often undertaken as in the story, when the individual fears the death of self or of a loved one. The suffering, though, can transform. The self-awareness gained leads to a more gentler way of being, and compassion results. This compassion is borne of understanding, recognition, and appreciation that the frailties of human nature exist in each of us. Recognizing and applying this to all manner of relationships in our lives is the wisdom that compassion gives to our existence.

    Ruddy, Meaghan P; Thomas-Hemak, Linda; Meade, Lauren

    2016-05-01

    Current efforts to achieve practice transformation in our health care delivery system are, for good reason, primarily focused on technical change. Such efforts include meaningful use, population health metrics reporting, and the creation and sustaining of team-based patient-centered medical home delivery sites. If practice transformation is meant to ultimately and fundamentally transform the health care system and its culture to achieve the quadruple aim of better health, better care, affordability, and satisfaction of patients and providers, these technical changes are necessary but not sufficient. Systemic transformation is contingent on the transformation of the individuals who make up the systems. Therefore, if the goal is to authentically transform medical practice in the United States, transformation of those who practice it is also required.

    2005-06-01

    Full Text Available We review the progress achieved in optical information processing during the last decade by applying fractional linear integral transforms. The fractional Fourier transform and its applications for phase retrieval, beam characterization, space-variant pattern recognition, adaptive filter design, encryption, watermarking, and so forth is discussed in detail. A general algorithm for the fractionalization of linear cyclic integral transforms is introduced and it is shown that they can be fractionalized in an infinite number of ways. Basic properties of fractional cyclic transforms are considered. The implementation of some fractional transforms in optics, such as fractional Hankel, sine, cosine, Hartley, and Hilbert transforms, is discussed. New horizons of the application of fractional transforms for optical information processing are underlined.

    2010-01-15

    This article discussed new transformers built for a tie-in between American Electric Power (AEP) and Allegheny Energy (AE). The transformers were designed to increase electric transmission capabilities while increasing system reliability. The autotransformers had a large MVA rating, a high primary voltage, a very high low voltage, and low tertiary voltage ratings. The transformers weighed approximately 260 tons each and were installed at a substation site near Moundsville, West Virginia. Tests conducted on the units included special temperature rise tests; fast front switching impulse tests; and special termination lightening impulse tests. The tests were conducted to ensure the safe operation of the transformer insulation and cooling systems as well as for the overall transformer design. The core and coil assembly were designed to ensure that the transformers could be easily transported by rail. It was concluded that the transformers are enhancing electric power supply in the region. 4 figs.

    2016-01-01

    Unknown compounds in environmental samples are difficult to identify using standard mass spectrometric methods. Fourier transform mass spectrometry (FTMS) has revolutionized how environmental analyses are performed. With its unsurpassed mass accuracy, high resolution and sensitivity, researchers now have a tool for difficult and complex environmental analyses. Two features of FTMS are responsible for changing the face of how complex analyses are accomplished. First is the ability to quickly and with high mass accuracy determine the presence of unknown chemical residues in samples. For years, the field has been limited by mass spectrometric methods that were based on knowing what compounds of interest were. Secondly, by utilizing the high resolution capabilities coupled with the low detection limits of FTMS, analysts also could dilute the sample sufficiently to minimize the ionization changes from varied matrices.

    Full Text Available Unknown compounds in environmental samples are difficult to identify using standard mass spectrometric methods. Fourier transform mass spectrometry (FTMS has revolutionized how environmental analyses are performed. With its unsurpassed mass accuracy, high resolution and sensitivity, researchers now have a tool for difficult and complex environmental analyses. Two features of FTMS are responsible for changing the face of how complex analyses are accomplished. First is the ability to quickly and with high mass accuracy determine the presence of unknown chemical residues in samples. For years, the field has been limited by mass spectrometric methods that were based on knowing what compounds of interest were. Secondly, by utilizing the high resolution capabilities coupled with the low detection limits of FTMS, analysts also could dilute the sample sufficiently to minimize the ionization changes from varied matrices.

    Each local health economy has been tasked with producing a sustainability and transformation plan. A health economy is a system that controls and contributes to health-care resource and the effects of health services on its population. This includes commissioners, acute providers, primary care providers, community services, public health and the voluntary sector. Sustainability and transformation plans represent a shift in the way health care is planned for in England. The aim of each sustainability and transformation plan is to deliver care within existing resource limits by improving quality of care, developing new models of care and improving efficiency of care provision. The tight timescales for production of sustainability and transformation plans mean that in most cases there has been limited clinical engagement; as a result many clinicians have limited sight, understanding or ownership of the proposals within sustainability and transformation plans. As sustainability and transformation plans move into the implementation phase, this article explores the role of the clinician in the ongoing design and delivery of the local sustainability and transformation plans. By finding the common ground between the perspectives of the clinician, the commissioner and system leaders, the motivation of clinicians can be aligned with the ambitions of the sustainability and transformation plan. The common goal of a sustainability and transformation plan and the necessary collaboration required to make it successful is discussed. Ultimately, such translation is essential: clinicians are intelligent, adaptive and motivated individuals who must have a lead role in constructing and implementing plans that transform health and social care.

    Shock waves are one of the most competent mechanisms of energy dissipation observed in nature. We have developed a novel device to generate controlled micro-shock waves using an explosive-coated polymer tube. In this study, we harnessed these controlled micro-shock waves to develop a unique bacterial transformation method. The conditions were optimized for the maximum transformation efficiency in Escherichia coli. The maximum transformation efficiency was obtained when we used a 30 cm length polymer tube, 100 μm thick metal foil, 200 mM CaCl(2), 1 ng/μl plasmid DNA concentration, and 1×10(9) cell density. The highest transformation efficiency achieved (1×10(-5) transformants/cell) was at least 10 times greater than the previously reported ultrasound-mediated transformation (1×10(-6) transformants/cell). This method was also successfully employed for the efficient and reproducible transformation of Pseudomonas aeruginosa and Salmonella typhimurium. This novel method of transformation was shown to be as efficient as electroporation with the added advantage of better recovery of cells, reduced cost (40 times cheaper than a commercial electroporator), and growth phase independent transformation.

  19. The transformations of Tibetan medicine.

    This article presents a cultural and historical analysis of 20th-century Tibetan medicine. In its expansion into the state bureaucracy, Tibetan medicine has acceded to institutional modernity through transformations in theory, practice, and methods for training physicians. Despite Chinese rule in Tibet, however, Tibetan medicine has not yielded completely to state interests. With the collapsing of the traditionally pluralistic Tibetan health system into the professional sector of Tibetan medicine, contemporary Tibetan medicine has become to the laity a font of ethnic revitalization and resistance to the modernization policies of the Chinese state. These processes are particularly evident in the elaboration of disorders of rlung, a class of sicknesses that, collectively, have come to symbolize the suffering inherent in rapid social, economic, and political change.

    Multigene transformation (MGT) is becoming routine in plant biotechnology as researchers seek to generate more complex and ambitious phenotypes in transgenic plants. Every nuclear transgene requires its own promoter, so when coordinated expression is required, the introduction of multiple genes leads inevitably to two opposing strategies: different promoters may be used for each transgene, or the same promoter may be used over and over again. In the former case, there may be a shortage of different promoters with matching activities, but repetitious promoter use may in some cases have a negative impact on transgene stability and expression. Using illustrative case studies, we discuss promoter deployment strategies in transgenic plants that increase the likelihood of successful and stable multiple transgene expression.
