    Reports an error in "Individual differences in the executive control of attention, memory, and thought, and their associations with schizotypy" by Michael J. Kane, Matt E. Meier, Bridget A. Smeekens, Georgina M. Gross, Charlotte A. Chun, Paul J. Silvia and Thomas R. Kwapil (Journal of Experimental Psychology: General, 2016[Aug], Vol 145[8], 1017-1048). There were errors in Table 3 and Table 7 (these transcription errors were limited to descriptive statistics in the Tables and did not affect any inferential statistics). In Table 3, the ARRO-TUT and LETT-TUT variables had incorrect values for Mean [95% CI], SD, Skew, Kurtosis, and N. In Table 7, the same values (plus Min and Max) were incorrect for the SEM-SART variable. The correct values for these measures are presented in the correction (the values for Min and Max were correct as set in Table 3, but are repeated below for clarity). (The following abstract of the original article appeared in record 2016-29680-001.) A large correlational study took a latent-variable approach to the generality of executive control by testing the individual-differences structure of executive-attention capabilities and assessing their prediction of schizotypy, a multidimensional construct (with negative, positive, disorganized, and paranoid factors) conveying risk for schizophrenia. Although schizophrenia is convincingly linked to executive deficits, the schizotypy literature is equivocal. Subjects completed tasks of working memory capacity (WMC), attention restraint (inhibiting prepotent responses), and attention constraint (focusing visual attention amid distractors), the latter 2 in an effort to fractionate the "inhibition" construct. We also assessed mind-wandering propensity (via in-task thought probes) and coefficient of variation in response times (RT CoV) from several tasks as more novel indices of executive attention. WMC, attention restraint, attention constraint, mind wandering, and RT CoV were correlated but separable

  12. Sources for Skinner's pragmatic selectionism in 1945.

    Science.gov (United States)

    Moxley, R A

    2001-01-01

    Skinner's pragmatic selectionism shows up strongly in his 1945 publication, "The Operational Analysis of Psychological Terms," in which he introduced a probabilistic three-term contingency for verbal behavior. This probabilism was accompanied by an expanded contextualism and an increased emphasis on consequences with a clear alignment to pragmatism. In total, these changes represent Skinner's most striking shift from mechanistic and necessitarian values to pragmatic selectionism, and these changes may be indebted more to the conceptual contributions of others than Skinner acknowledged. Before 1945, Skinner made at least some positive associations with the views of Watson, Russell, and Carnap. From 1945 and afterwards, he strongly disassociated his views on verbal behavior from theirs. Before 1945, Skinner did not associate his views with those of Darwin or Peirce. After 1945, he strongly associated his views with those of Darwin and Peirce (in one published interview). No sources for his pragmatic selectionism, however, were referred to in 1945.

    The language literature contains many citations to Skinner's book Verbal Behavior (1957), however, most of them are negative and generally unsupportive. The current list of references was assembled to bring readers in contact with the growing body of literature which supports Skinner's work. A total of 136 references were found and divided into two categories, (1) conceptual, and (2) experimental and applied. These references are presented in an effort to stimulate additional research in this important aspect of behavior analysis. PMID:22573391

    Bloomfield's "Linguistics as a Science" (1930/1970), Language (1933/1961), and "Language or Ideas?" (1936a/1970), and Skinner's Verbal Behavior (1957) and Science and Human Behavior (1953) were analyzed in regard to their respective perspectives on science and scientific method, the verbal episode, meaning, and subject matter. Similarities between the two authors were found. In particular both asserted that (a) the study of language must be carried out through the methods of science; (b) the main function of language is to produce practical effects on the world through the mediation of a listener; and (c) a physicalist conception of meaning. Their differences concern the subject matter of their disciplines and their use of different models for the analysis of behavior. Bloomfield's linguistics and Skinner's functional analysis of verbal behavior are complementary approaches to language.

    2006-01-01

    Formal and functional analyses of verbal behavior have been often considered to be divergent and incompatible. Yet, an examination of the history of part of the analytical approach used in Verbal Behavior (Skinner, 1957/1992) for the identification and conceptualization of verbal operant units discloses that it corresponds well with formal analyses of languages. Formal analyses have been carried out since the invention of writing and fall within the scope of traditional grammar and structural linguistics, particularly in analyses made by the linguist Leonard Bloomfield. The relevance of analytical instruments originated from linguistic studies (which examine and describe the practices of verbal communities) to the analysis of verbal behavior, as proposed by Skinner, relates to the conception of a verbal community as a prerequisite for the acquisition of verbal behavior. A deliberately interdisciplinary approach is advocated in this paper, with the systematic adoption of linguistic analyses and descriptions adding relevant knowledge to the design of experimental research in verbal behavior.

    1990-01-01

    Skinner's Verbal Behavior (1957) is a comprehensive treatise that deals with most aspects of verbal behavior. However, its treatment of the learning of grammatical behavior has been challenged repeatedly (e.g., Chomsky, 1959). The present paper will attempt to show that the learning of grammar and syntax can be dealt with adequately within a behavior-analytic framework. There is no need to adopt mentalist (or cognitivist) positions or to add mentalist elements to behaviorist theories. PMID:2103585

    Altus, Deborah E; Morris, Edward K

    2009-01-01

    This paper addresses B. F. Skinner's utopian vision for enhancing social justice and human well-being in his 1948 novel, Walden Two. In the first part, we situate the book in its historical, intellectual, and social context of the utopian genre, address critiques of the book's premises and practices, and discuss the fate of intentional communities patterned on the book. The central point here is that Skinner's utopian vision was not any of Walden Two's practices, except one: the use of empirical methods to search for and discover practices that worked. In the second part, we describe practices in Skinner's book that advance social justice and human well-being under the themes of health, wealth, and wisdom, and then show how the subsequent literature in applied behavior analysis supports Skinner's prescience. Applied behavior analysis is a measure of the success of Skinner's utopian vision: to experiment.

    The central theme in the chapter 'Humanoria' of the novel 'Der Zauberberg' by Thomas Mann is a discussion focusing on the skin, where the dialogue takes place on a number of different levels. The physiological facts are construed as double meanings for the erotic sensitivity of man and highlight the artful linguistic skills of the author, Thomas Mann. An intensive portrayal of different diseases and the notion of disease itself as a part of mankind are main elements of Mann's novel. In this essay, Thomas Mann's genius as a novelist is honoured against the background of poor modern literacy of the internet age.

Drawing upon Georges Didi-Huberman’s Survivance des lucioles (2009, the text sheds light on the question of hope in what has been seen as pessimism in Kane’s work. Rather than understanding Kane’s fragmented, sarcastic and provocative writing as a testament of a clinically depressed author, Delvaux sees it as a work of resistance, a desire to see the light in an all-encompassing cultural darkness, suggesting that Kane, in fact, refuses the cynical posturethat critics have associated with her work.

  16. Skinner and the rise of behavior modification and behavior therapy.

    Science.gov (United States)

    Labrador, Francisco Javier

    2004-11-01

    Skinner is, without a doubt, one of the most predominant figures in the development of Behavior Modification and Behavior Therapy. Skinners' work is essential to the development of Behavior Modification and Behavior Therapy. Beginning with the social need for efficient psychotherapy, and after having generated a solid theoretical body of behavioral laws, Skinner indicated and also developed the appropriate path towards efficient interventions for unadaptive behavior. He developed a new theory regarding abnormal behavior (psychopathology), as well as a procedural model for evaluation (diagnosis) and intervention: "The functional analysis of behavior". His applications for this kind of work are pioneering and at the same time, he is the agglutinant figure of what we today call "Behavior Modification and/or Therapy". It is remarkable that a scientist could change the theories and practices of a discipline as radically as Skinner and his work did. His work, however, still has its limitations. The best way to acknowledge and pay tribute to Skinners' work is to overcome these limitations.

    2013-01-01

    Behaviorism and psychodynamic psychology have been regarded as polar opposites. Contrary to popular belief, B. F. Skinner took an interest in Freud and many of his concepts, and agreed to be tested with the Rorschach method and the Thematic Apperception Test by Roe in her study of scientists (Roe, 1953 ). We looked for signs of creativity defined as complex responses, an intriguing emotional tone, novelty, and liveliness. Skinner displayed an enormous number of responses characterized by simplicity, an intellectualized tone, a driven quality rather than creative complexity, and a sense of strained social relationships and lack of liveliness. The findings are in line with Roe's study of other scientists. Skinner's intellectual productivity and high ambition fits well with the commanding figure history describes.

    2000-01-01

    The current article suggests a possible synthesis of Skinner's (1957) treatment of verbal behavior with the more recent behavioral interpretation of language known as relational frame theory. The rationale for attempting to combine these two approaches is first outlined. Subsequently, each of the verbal operants described by Skinner is examined and subjected to a relational frame analysis. In each case, two types of operants are identified; one based on direct contingencies of reinforcement and the other based on arbitrarily applicable relational responding. The latter operants are labeled verbal because they can be distinguished from other forms of social behavior, and they appear to possess the symbolic or referential qualities often ascribed to human language. By applying relational frame theory to Skinner's verbal operants, we aim to contribute towards the development of a modern behavior-analytic research agenda in human language and cognition.

    Many microgravity space science experiments require vibratory acceleration levels unachievable without active isolation. The Boeing Corporation's Active Rack Isolation System (ARIS) employs a novel combination of magnetic actuation and mechanical linkages to address these isolation requirements on the International Space Station (ISS). ARIS provides isolation at the rack (International Standard Payload Rack (ISPR)) level. Effective model-based vibration isolation requires: (1) an appropriate isolation device, (2) an adequate dynamic (i.e., mathematical) model of that isolator, and (3) a suitable, corresponding controller. ARIS provides the ISS response to the first requirement. This paper presents one response to the second, in a state space framework intended to facilitate an optimal-controls approach to the third. The authors use "Kane's Dynamics" to develop a state-space, analytical (algebraic) set of linearized equations of motion for ARIS.

The authors use "Kane's Dynamics" to develop an state-space, analytical (algebraic) set of linearized equations of motion for ARIS.

    We review why the Thomas rotation is a crucial facet of special relativity, that is just as fundamental, and just as "unintuitive" and "paradoxical", as such traditional effects as length contraction, time dilation, and the ambiguity of simultaneity. We show how this phenomenon can be quite naturally introduced and investigated in the context of a typical introductory course on special relativity, in a way that is appropriate for, and completely accessible to, undergraduate students. We also demonstrate, in a more advanced section aimed at the graduate student studying the Dirac equation and relativistic quantum field theory, that careful consideration of the Thomas rotation will become vital as modern experiments in particle physics continue to move from unpolarized to polarized cross-sections.

    For many centuries, medicine has practiced in a vacuum, and the healthcare profession has been isolated from other scientific disciplines. Beginning in the 20th century, doctors and scientists have looked to others for ideas, suggestions, innovations, and new technologies. Probably no one in the past hundred years has done so much to change the world than Thomas Edison. This article will discuss eight principles of Edison and how they may apply to our profession and our practices.

    Since 1990, Margaret E. O'Kane has served as president of the National Committee for Quality Assurance (NCQA), an independent, not-for-profit organization whose mission is to improve the quality of healthcare everywhere. Under O'Kane's leadership, NCQA has developed broad support among the employer and health plan communities; today many Fortune 100 companies will do business only with NCQA-accredited health plans. About three quarters of the nation's largest employers use Health Plan Employer Data and Information Set (HEDIS) data to evaluate the plans that serve their employees. O'Kane was named Health Person of the Year in 1996 by the journal Medicine & Health. She also received a 1997 Founder's Award from the American College of Medical Quality, recognizing NCQA's efforts to improve managed care quality. In 1999, O'Kane was elected a member of the Institute of Medicine. In 2000, she received the Centers for Disease Control and Prevention (CDC) Champion of Prevention award, the agency's highest honor. CDC names a Champion of Prevention infrequently and only when an individual has made a truly notable contribution to advancing preventive healthcare. O'Kane began her career in healthcare as a respiratory therapist and has a master's degree in health administration and planning from Johns Hopkins University.

    The Lagrangian-Hamiltonian unified formalism of R. Skinner and R. Rusk was originally stated for autonomous dynamical systems in classical mechanics. It has been generalized for non-autonomous first-order mechanical systems, first-order and higher-order field theories, and higher-order autonomous systems. In this work we present a generalization of this formalism for higher-order non-autonomous mechanical systems.

    2000-11-01

    B. F. Skinner is perhaps 2nd only to Freud among the most publicly identifiable psychological figures of the last century. This article reviews the popular press coverage of Skinner between 1934 and 1990 to examine how radical behaviorism was interpreted, portrayed, and received by psychology's public. Reactions to Skinner were often skeptical or condemnatory. It is suggested that some members of the public had difficulty accepting his views because of the disparities between the philosophy of radical behaviorism and the phenomenology of everyday experience. Furthermore, Skinner's status as a psychological expert was inextricably linked to the public's perception of his credibility not only as a scientist but also as a human being.

    2017-01-01

    Full Text Available We propose an improved Kane dynamic model theory for the 7-DOF modular robot in this paper, and the model precision is improved by the improved function T′it. We designed three types of progressive modular joints for reconfigurable modular robot that can be used in industrial robot, space robot, and special robot. The Kane dynamic model and the solid dynamic model are established, respectively, for the 7-DOF modular robot. After that, the experimental results are obtained from the simulation experiment of typical task in the established dynamic models. By the analysis model of error, the equation of the improved torque T′it is derived and proposed. And the improved Kane dynamic model is established for the modular robot that used T′it. Based on the experimental data, the undetermined coefficient matrix is five-order linear that was proved in 7-DOF modular robot. And the explicit formulation is solved of the Kane dynamic model and can be used in control system.

    A geometric approach to time-dependent optimal control problems is proposed. This formulation is based on the Skinner and Rusk formalism for Lagrangian and Hamiltonian systems. The corresponding unified formalism developed for optimal control systems allows us to formulate geometrically the necessary conditions given by a weak form of Pontryagin's maximum principle, provided that the differentiability with respect to controls is assumed and the space of controls is open. Furthermore, our method is also valid for implicit optimal control systems and, in particular, for the so-called descriptor systems (optimal control problems including both differential and algebraic equations).

  6. St. Thomas Aquinas, Dramatist?

    Directory of Open Access Journals (Sweden)

    Eric McLuhan

    2016-03-01

    Full Text Available The article begins with the statement that there is one aspect of St Thomas’s work that has not received due scrutiny as a literary form, one with solid dramatic qualities and structure: the Article. The Article is as Thomistic as the syllogism is Aristotelian. This particular mode of argument was evidently original with St. Thomas: he did not derive it from the work of any other writer, yet its inner movement is of the essence of dialectic, from the opening proposition to opposing objections, then “to the contrary” position as found in orthodoxy, and then the writer’s resolution, and so on. It is a variation on the classic sic-et-non, a reasonable, balanced to and fro of the sort beloved by disputants. No parallel or even parody of this Article is to be found in any known literature before or since the thirteenth century. The author aims to show that part of the sheer power of the Article resides in the fact that it has two levels of operation. The surface is composed of the dialectical to-and-fro adumbrated above. But under that surface lies a rhetorical structure constructed along the lines of the five divisions of the rhetorical logos as laid out by Cicero and Horace.

  11. On Chomsky's Appraisal of Skinner's Verbal Behavior: A Half Century of Misunderstanding

    2006-01-01

    The history of the writing of Verbal Behavior (Skinner, 1957), Chomsky's review (1959), and MacCorquodale's rebuttal (1970) are briefly summarized. Chomsky's recent reflections on his review are analyzed: Chomsky's refusal to acknowledge the review's errors or its aggressive tone is consistent with his polemical style but comes at a minor cost in consistency and plausibility. However, his remarks about the place of Skinner's work in science reveal misunderstandings so great that they undercut the credibility of the review substantially. The gradual growth in the influence of Skinner's book suggests that its legacy will endure. PMID:22478467

    2013-01-01

    Equations of motion are derived for a general spacecraft composed of rigid bodies connected via rotary (spherical or gimballed) joints in a tree topology. Several supporting concepts are developed in depth. Basis dyads aid in the transition from basis-free vector equations to component-wise equations. Joint partials allow abstraction of 1-DOF, 2-DOF, 3-DOF gimballed and spherical rotational joints to a common notation. The basic building block consisting of an "inner" body and an "outer" body connected by a joint enables efficient organization of arbitrary tree structures. Kane's equation is recast in a form which facilitates systematic assembly of large systems of equations, and exposes a relationship of Kane's equation to Newton and Euler's equations which is obscured by the usual presentation. The resulting system of dynamic equations is of minimum dimension, and is suitable for numerical solution by computer. Implementation is ·discussed, and illustrative simulation results are presented.

    We report on optical reflectivity experiments performed on Cd3 As2 over a broad range of photon energies and magnetic fields. The observed response clearly indicates the presence of 3D massless charge carriers. The specific cyclotron resonance absorption in the quantum limit implies that we are probing massless Kane electrons rather than symmetry-protected 3D Dirac particles. The latter may appear at a smaller energy scale and are not directly observed in our infrared experiments.

    It has recently been shown that electronic states in bulk gapless HgCdTe offer another realization of pseudo-relativistic three-dimensional particles in condensed matter systems. These single valley relativistic states, massless Kane fermions, cannot be described by any other relativistic particles. Furthermore, the HgCdTe band structure can be continuously tailored by modifying cadmium content or temperature. At critical concentration or temperature, the bandgap collapses as the system undergoes a semimetal-to-semiconductor topological phase transition between the inverted and normal alignments. Here, using far-infrared magneto-spectroscopy we explore the continuous evolution of band structure of bulk HgCdTe as temperature is tuned across the topological phase transition. We demonstrate that the rest mass of Kane fermions changes sign at critical temperature, whereas their velocity remains constant. The velocity universal value of (1.07+/-0.05) × 106 m s-1 remains valid in a broad range of temperatures and Cd concentrations, indicating a striking universality of the pseudo-relativistic description of the Kane fermions in HgCdTe.

  16. Modeling of a space flexible probe–cone docking system based on the Kane method

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Recent developments in micro- and nano-satellites have attracted the interest of the research community worldwide. Many colleges and corporations have launched their satellites in space. Meanwhile, the space flexible probe–cone docking system for micro- and nano-satellites has become an attractive topic. In this paper, a dynamic model of a space flexible probe–cone docking system, in which the flexible beam technology is applied, is built based on the Kane method. The curves of impact force versus time are obtained by the Lagrange model, the Kane model, and the experimental method. The Lagrange model was presented in the reference and verified by both finite element simulation and experiment. The results of the three methods show good agreements on the condition that the beam flexibility and the initial relative velocity change. It is worth mentioning that the introduction of vectorial mechanics and analytical mechanics in the Kane method leads to a large reduction of differential operations and makes the modeling process much easier than that of the Lagrange method. Moreover, the influences of the beam flexibility and the initial relative velocity are discussed. It is concluded that the initial relative velocity of space docking operation should be controlled to a certain value in order to protect the docking system.

    It is frequently claimed that the influence of behaviorism in general and of B. F. Skinner in particular, is declining. Data obtained from the Social Sciences Citation Index for the years 1966-1989 document that in the last twenty-four years the number of citations to the works of Skinner has been reasonably steady. There is no evidence of a decline in the absolute number of such citations, suggesting that claims of the demise of behaviorism may be, once again, premature.

  20. Thomas-Wigner rotation and Thomas precession: actualized approach

    CERN Document Server

    Kholmetskii, Alexander

    2014-01-01

    We show that the explanation of Thomas-Wigner rotation (TWR) and Thomas precession (TP) in the framework of special theory of relativity (STR) contains a number of points of inconsistency, in particular, with respect to physical interpretation of the Einstein velocity composition law in successive space-time transformations. In addition, we show that the common interpretation of TP falls into conflict with the causality principle. In order to eliminate such a conflict, we suggest considering the velocity parameter, entering into expression for the frequency of TP, as being always related to a rotation-free Lorentz transformation. Such an assumption (which actually resolves any causal paradoxes with respect to TP), comes however to be in contradiction with the spirit of STR. The results obtained are discussed.

    Thomas Hodgkin (1798-1866), born into a family of Quakers, would remain faithful all his life to the principles and rules of the 'Society of Friends'. He studied pharmacy and medicine in London, Edinburgh and Paris. As curator for the museum of pathological anatomy of Guy's Hospital (1825-1837) he introduced modern, organ-based, medicine in England, together with the clinicians Richard Bright and Thomas Addison. In 1832 Hodgkin reported autopsy findings of seven patients who had shown swollen lymph glands and an enlarged spleen, without evidence of tuberculosis, purulent inflammation or cancer. Later the diagnosis 'Hodgkin's disease' would be restricted to lymphomas with giant, multinucleated Reed-Sternberg cells on microscopic examination. Especially in his later years, Hodgkin devoted much time and effort to the emancipation of oppressed or destitute minorities, especially abroad. He died of dysentery on a journey to Palestine and lies buried in Jaffa.

    2014-11-12

    The phase diagram of the Kane-Mele-Heisenberg model in a classical limit [47] contains disordered regions in the coupling space, as the result of competition between different terms in the Hamiltonian, leading to frustration in finding a unique ground state. In this work we explore the nature of these phases in the quantum limit, for a S = 1/2. Employing exact diagonalization in Sz and nearest neighbour valence bond bases, and bond and plaquette valence bond mean field theories, we show that the disordered regions are divided into ordered quantum states in the form of plaquette valence bond crystals and staggered dimerized phases.

    2016-12-01

    We calculate and present an analytic form of the magneto-optical conductivity for the gapped low-energy Kane model in two and three dimensions separately. The two-dimensional case maps onto the α -T3 model at a particular value of α =1 /√{3 } . In two dimensions, two chiral sectors exist, between which there are no optically activated transitions. In three dimensions, the extra dimension of dispersion mixes the two sectors so that intra- and intersector transitions can occur. The latter type of transition can be separated out via circular polarizations of light, and it shows a distinct signature in the transverse conductivity.

    The spin-orbit coupling strength of graphene can be enhanced by depositing iridium nanoclusters. Weak localization is intensely suppressed near zero fields after the cluster deposition, rather than changing to weak anti-localization. Fitting the magnetoresistance gives the spin relaxation time, which increases by two orders with the application of a back gate. The spin relaxation time is found to be proportional to the electronic elastic scattering time, demonstrating the Elliot-Yafet spin relaxation mechanism. A sizeable Kane-Mele-like coupling strength of over 5.5 meV is determined by extrapolating the temperature dependence to zero.

    We determine the nonlinear transformations between coordinate systems which are mutually in a constant symmetrical accelerated motion. The maximal acceleration limit follows from the kinematical origin and it is an analogue of the maximal velocity in special relativity. We derive the dependence of mass, length, time, Doppler effect, Cherenkov effect and transition radiation angle on acceleration as an analogue phenomena in special theory of relativity. The last application of our method is the Thomas precession by uniform acceleration with the possible role in the modern physics and cosmology. The comparison of derived results with other relativistic methods is necessary.

  6. A history of the term radical behaviorism: From Watson to Skinner

    Science.gov (United States)

    Schneider, Susan M.; Morris, Edward K.

    1987-01-01

    This paper describes the origins and evolution of the term radical behaviorism. John B. Watson's coining of behaviorism in 1913 is presented first, followed by a discussion of the uses of “radical” within psychology during these early years. When the term radical behaviorism first emerged in the early 1920s, its referent was Watson's behaviorism, most specifically his stance on consciousness. In the 1930s, B. F. Skinner described his own position with the term radical behaviorism in an unpublished manuscript, and then in 1945 first referred in print to his views as such. Today, radical behaviorism is generally applied to Skinner's views alone. The paper concludes with a brief discussion of a similarity in Watson's and Skinner's positions on consciousness, which seems a possible historical and philosophical connection between their respective radical behaviorisms.

  10. Verbal understanding: Integrating the conceptual analyses of Skinner, Ryle, and Wittgenstein.

    1991-01-01

    Gilbert Ryle's (1949) and Ludwig Wittgenstein's (1953; 1958; 1974/78) conceptual analyses of verbal understanding are presented. For Ryle, the term understanding signifies simultaneously an acquired disposition and a behavioral episode. For Wittgenstein, it signifies simultaneously a skill and a criterial behavior. Both argued that episodes of understanding comprise heterogenious classes of behaviors, and that each member of such a class is neither a necessary nor a sufficient condition of understanding. Next, an approach integrating the analyses of Ryle and Wittgenstein with that of Skinner is presented. Lastly, it is argued that this integrated analysis adequately counters Parrott's (1984) argument that understanding, for Skinner, is potential behavior and not an event.

    Verbal Behavior by B.F. Skinner, represents a systematic extrapolation of the concepts and principles of operant conditioning to account for language as behavior. I examine the logic and conceptual deficiencies of Skinner’s formulation, based upon the analysis of a limited number of problems: a) the definition of verbal behavior, b) the selection of the ‘word’ as the dominant unit of analysis, c) the morphological nature of the taxonomy of verbal behavior, d) the lack of systematicness of suc...

  12. Generalized Donaldson-Thomas invariants

    2009-01-01

    This is a summary of the much longer paper arXiv:0810.5645 with Yinan Song. Let X be a Calabi-Yau 3-fold over C. The Donaldson-Thomas invariants of X are integers DT^a(t) which count stable sheaves with Chern character a on X, with respect to a Gieseker stability condition t. They are defined only for Chern characters a for which there are no strictly semistable sheaves on X. They have the good property that they are unchanged under deformations of X. Their behaviour under change of stability condition t was not understood until now. We discuss "generalized Donaldson-Thomas invariants" \\bar{DT}^a(t). These are rational numbers, defined for all Chern characters a, and are equal to DT^a(t) if there are no strictly semistable sheaves in class a. They are deformation-invariant, and have a known transformation law under change of stability condition. We conjecture they can be written in terms of integral "BPS invariants" \\hat{DT}^a(t) when the stability condition t is "generic". We extend the theory to abelian cat...

  19. Benjamin Franklin and the dentist: the story of R. C. Skinner.

    Science.gov (United States)

    Ring, Malvin

    2006-01-01

    Among Benjamin Franklin's papers was a letter from a young British immigrant, R. C. Skinner, asking for a loan of only twenty dollars to help this young man begin the practice of dentistry in this country. Although we don't know what the great man's response was to this appeal, Skinner went on to achieve fame in his profession. He was the first dentist ever, in this country, to be appointed to a hospital staff; he established the first free dental clinic for the poor; and he authored the first book on dentistry ever published in America, earning him the title "The Father of American Dental Literature." From a newspaper advertisement of 1794, further information has been gleaned about Skinner's practice: he not only did conventional dentistry, but also supplied missing eyes, ears, noses and legs. This was a forerunner of the contemporary subspecialty of prosthodontics termed "maxillofacial prosthetics". An interesting list of Skinner's services and his fees for each, gives us a good picture of what dentistry was like in Colonial America.

    2016-11-01

    We study a spin Hamiltonian for spin-orbit-coupled ferromagnets on the honeycomb lattice. At sufficiently low temperatures supporting the ordered phase, the effective Hamiltonian for magnons, the quanta of spin-wave excitations, is shown to be equivalent to the Haldane model for electrons, which indicates the nontrivial topology of the band and the existence of the associated edge state. At high temperatures comparable to the ferromagnetic-exchange strength, we take the Schwinger-boson representation of spins, in which the mean-field spinon band forms a bosonic counterpart of the Kane-Mele model. The nontrivial geometry of the spinon band can be inferred by detecting the spin Nernst effect. A feasible experimental realization of the spin Hamiltonian is proposed.

  18. The topological Anderson insulator phase in the Kane-Mele model.

    Science.gov (United States)

    Orth, Christoph P; Sekera, Tibor; Bruder, Christoph; Schmidt, Thomas L

    2016-04-05

    It has been proposed that adding disorder to a topologically trivial mercury telluride/cadmium telluride (HgTe/CdTe) quantum well can induce a transition to a topologically nontrivial state. The resulting state was termed topological Anderson insulator and was found in computer simulations of the Bernevig-Hughes-Zhang model. Here, we show that the topological Anderson insulator is a more universal phenomenon and also appears in the Kane-Mele model of topological insulators on a honeycomb lattice. We numerically investigate the interplay of the relevant parameters, and establish the parameter range in which the topological Anderson insulator exists. A staggered sublattice potential turns out to be a necessary condition for the transition to the topological Anderson insulator. For weak enough disorder, a calculation based on the lowest-order Born approximation reproduces quantitatively the numerical data. Our results thus considerably increase the number of candidate materials for the topological Anderson insulator phase.

    Rambely, A. S.; Fazrolrozi

    A biomechanics model of six-link kinematic chain of human body is developed by using Kane's method. The kinematic data comprise of six segments; foot, calf, thigh, trunk, upper arm and forearm, are obtained through data collection of walking, running and jumping using the Vicon Nexus system. The motion capture system uses 12 Vicon MX-3+ cameras and 12 Vicon MX-F40 cameras, two DV (50 Hz) cameras and a force plate (100 Hz). Inverse dynamics approach is used to obtain the unknown value of torques produced by joint segments during walking, running and jumping activities. The results show that the largest value of torques produced occurs at the foot segment.

  20. VARIATIONS IN CRUSTAL THICKNESS OF THE KANE TRANSFORM IN THE NORTH ATLANTIC OCEAN

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    A new approach was taken to investigate the crustal stucture of the Kane transform and its aseismic extension, using high quality bathymetry and gravity data. The gravity signatures associated with variations in crustal thickness of the transform were isolated from the observed free-air anomaly,was continued downward to the mean depth of the crust/mantle interface and converted onto the relief on that surface. The crustal thickness of the transform was then calculated by subtracting seawater depth from the depth of the gravity-inferred crust/mantle interface. 3-D gravity investigation results indicate that the Kane transform and adjacent areas are associated with a crust thinner than normal oceanic crust. The transform trough is largely underlain by a crust less than 4.5km thick and in the nodal basins the crust may be as thin as 3 km. The crust beneath the fracture zone valley is 4 - 5.5 km thick. The rift valleys on the spreading segments are also characterized by thin crust (4 - 5 km thick). Thin oceanic crust extends to 20 - 30 km from the transform axis, except for some localized places such as the inside comer highs adjoining the ridge-transform intersections. These gravity-inferred results match fairly well with limited published seismic results. Thinning of the crust is mainly attributable to a thin layer 3, which in tum may be explained by the combined effects of reduced magma supply at the ends of the spreading segments and tectonic activities in the region.

  2. Survival or collapse? B. F. Skinner, J. M. Diamond and the fate of cultures / Sobrevivência ou colapso? B. F. Skinner, J. M. Diamond e o destino das culturas

    Directory of Open Access Journals (Sweden)

    Alexandre Dittrich

    2008-01-01

    Full Text Available One of the most interesting and polemic features of B. F. Skinner's work is his interpretation about cultural evolution. According to that author, the consequences of cultural practices have a retroactive effect over the cultures, increasing or decreasing their chances of survival. The book "Collapse" – written by the north-American biologist and geographer Jared Diamond – shows remarkable resemblances with Skinner's theory making clear that the consequences of cultural practices have a decisive influence over the fate of cultures. This paper aims to detail such resemblances, considering that Diamond's book serves as a complement to Skinner's theory, because it illustrates with concrete examples the general statements made by Skinner about cultural evolution and, by doing so, makes these statements clearer and more credible.

    The Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Newport News, Virginia, USA, is one of ten national laboratories under the aegis of the Office of Science of the U.S. Department of Energy (DOE). It is managed and operated by Jefferson Science Associates, LLC. The primary facility at Jefferson Lab is the Continuous Electron Beam Accelerator Facility (CEBAF) as shown in an aerial photograph in Figure 1. Jefferson Lab was created in 1984 as CEBAF and started operations for physics in 1995. The accelerator uses superconducting radio-frequency (srf) techniques to generate high-quality beams of electrons with high-intensity, well-controlled polarization. The technology has enabled ancillary facilities to be created. The CEBAF facility is used by an international user community of more than 1200 physicists for a program of exploration and study of nuclear, hadronic matter, the strong interaction and quantum chromodynamics. Additionally, the exceptional quality of the beams facilitates studies of the fundamental symmetries of nature, which complement those of atomic physics on the one hand and of high-energy particle physics on the other. The facility is in the midst of a project to double the energy of the facility and to enhance and expand its experimental facilities. Studies are also pursued with a Free-Electron Laser produced by an energy-recovering linear accelerator.

    Full Text Available Micrococcus luteus is a predominant member of skin microbiome. We here report on the genomic analysis of Micrococcus luteus strain O'Kane that was isolated from an elevator. The partial genome assembly of Micrococcus luteus strain O'Kane is 2.5 Mb with 2256 protein-coding genes and 62 RNA genes. Genomic analysis revealed metabolic versatility with genes involved in the metabolism and transport of glucose, galactose, fructose, mannose, alanine, aspartate, asparagine, glutamate, glutamine, glycine, serine, cysteine, methionine, arginine, proline, histidine, phenylalanine, and fatty acids. Genomic comparison to other M. luteus representatives identified the potential to degrade polyhydroxybutyrates, as well as several antibiotic resistance genes absent from other genomes.

    It will still in lack of a simulation platform used to learn the walking of underwater quadruped walking robot. In order to alleviate this shortage, a simulation platform for the underwater quadruped walking robot based on Kane dynamic model and CPG-based controller is constructed. The Kane dynamic model of the underwater quadruped walking robot is processed with a commercial package MotionGenesis Kane 5�3. The forces between the feet and ground are represented as a spring and damper. The relation between coefficients of spring and damper and stability of underwater quadruped walking robot in the stationary state is studied. The CPG-based controller consisted of Central Pattern Generator ( CPG) and PD controller is presented, which can be used to control walking of the underwater quadruped walking robot. The relation between CPG parameters and walking speed of underwater quadruped walking robot is investigated. The relation between coefficients of spring and damper and walking speed of underwater quadruped walking robot is studied. The results show that the simulation platform can imitate the stable walking of the underwater quadruped walking robot.

  11. Postfeminist construction of women's sexuality in The village bike by Penelope Skinner

    Directory of Open Access Journals (Sweden)

    Melita Novak

    2014-12-01

    Full Text Available Penelope Skinner's drama The Village Bike deals with issues ranging from pregnancy to sexuality, pornography and sexual exploration. In this article I focus on the way these issues are presented and explain why pornography and sexual exploration belong to the postfeminist ideology. Namely, the author uncritically deals with these issues, objectifies a woman's body and favours gender constructs. Contemporary British drama by women playwrights is not marked by its engagement with feminism even though it might declare itself as pro-feminist or feminist. Penelope Skinner is one of the contemporary playwrights. I try to present that even though her drama seems to appear provocative at first sight this is not really the case. The provocation does not offer a critical insight and distance. I argue that this drama is postfeminist because it mainstreams pornography and presents a peculiar view on the part of sexual liberation, which is very limited.

    Skinner's contributions to the understanding of behavior are typically viewed as being in sufficiently tight alignment with traditional science to prevent their amenability to alternative discourses such as hermeneutics. However, it is possible to identify several concepts at work in radical behaviorism that might constitute its common ground with hermeneutics. The coextensiveness of individual and environment, the emphasis on contingency, and the interminableness of conversation promised by ...

    This paper describes the origins and evolution of the term radical behaviorism. John B. Watson's coining of behaviorism in 1913 is presented first, followed by a discussion of the uses of “radical” within psychology during these early years. When the term radical behaviorism first emerged in the early 1920s, its referent was Watson's behaviorism, most specifically his stance on consciousness. In the 1930s, B. F. Skinner described his own position with the term radical behaviorism in an unpubl...

    A novel "in vitro reinforcement" paradigm was used to investigate Skinner's (1953) hypotheses (a) that operant behavior is made up of infinitesimal "response elements" or "behavioral atoms" and (b) that these very small units, and not whole responses, are the functional units of reinforcement. Our tests are based on the assumption that behavioral atoms may plausibly be represented at the neural level by individual cellular responses.

  18. Kane Method Based Dynamics Modeling and Control Study for Space Manipulator Capturing a Space Target

    Directory of Open Access Journals (Sweden)

    Yanhua Han

    2016-01-01

    Full Text Available Dynamics modeling and control problem of a two-link manipulator mounted on a spacecraft (so-called carrier freely flying around a space target on earth’s circular orbit is studied in the paper. The influence of the carrier’s relative movement on its manipulator is considered in dynamics modeling; nevertheless, that of the manipulator on its carrier is neglected with the assumption that the mass and inertia moment of the manipulator is far less than that of the carrier. Meanwhile, we suppose that the attitude control system of the carrier guarantees its side on which the manipulator is mounted points accurately always the space target during approaching operation. The ideal constraint forces can be out of consideration in dynamics modeling as Kane method is used. The path functions of the manipulator’s end-effector approaching the space target as well as the manipulator’s joints control torque functions are programmed to meet the soft touch requirement that the end-effector’s relative velocity to the space target is zero at touch moment. Numerical simulation validation is conducted finally.

    2008-01-01

    Full Text Available Um dos aspectos mais interessantes e polêmicos da obra de B. F. Skinner é sua interpretação sobre a evolução das culturas. De acordo com o autor, as conseqüências de práticas culturais retroagem sobre as culturas, no sentido de aumentar ou diminuir suas chances de sobrevivência. O livro "Colapso", do biólogo e geógrafo norte-americano Jared Diamond, apresenta semelhanças marcantes com a teoria de Skinner, evidenciando que as conseqüências de práticas culturais têm influência decisiva sobre o destino das culturas. Este artigo busca detalhar tais semelhanças, argumentando que o livro de Diamond serve como complemento à teoria skinneriana, pois ilustra com exemplos concretos as afirmações gerais de Skinner sobre a evolução das culturas e, com isso, confere-lhes maior clareza e credibilidade.One of the most interesting and polemic features of B. F. Skinner's work is his interpretation about cultural evolution. According to that author, the consequences of cultural practices have a retroactive effect over the cultures, increasing or decreasing their chances of survival. The book "Collapse" - written by the north-American biologist and geographer Jared Diamond - shows remarkable resemblances with Skinner's theory making clear that the consequences of cultural practices have a decisive influence over the fate of cultures. This paper aims to detail such resemblances, considering that Diamond's book serves as a complement to Skinner's theory, because it illustrates with concrete examples the general statements made by Skinner about cultural evolution and, by doing so, makes these statements clearer and more credible.

    The k-cosymplectic Lagrangian and Hamiltonian formalisms of first-order classical field theories are reviewed and completed. In particular, they are stated for singular and almost-regular systems. Subsequently, several alternative formulations for k-cosymplectic first-order field theories are developed: First, generalizing the construction of Tulczyjew for mechanics, we give a new interpretation of the classical field equations. Second, the Lagrangian and Hamiltonian formalisms are unified by giving an extension of the Skinner-Rusk formulation on classical mechanics.

    A geometric approach to time-dependent optimal control problems is proposed. This formulation is based on the Skinner and Rusk formalism for Lagrangian and Hamiltonian systems. The corresponding unified formalism developed for optimal control systems allows us to formulate geometrically the necessary conditions given by a weak form of Pontryagin's maximum principle, provided that the differentiability with respect to controls is assumed and the space of controls is open. Furthermore, our method is also valid for implicit optimal control systems and, in particular, for the so-called descriptor systems (optimal control problems including both differential and algebraic equations)

  18. Kane-Mele Hubbard model on a zigzag ribbon: Stability of the topological edge states and quantum phase transitions

    Science.gov (United States)

    Chung, Chung-Hou; Lee, Der-Hau; Chao, Sung-Po

    2014-07-01

    We study the quantum phases and phase transitions of the Kane-Mele Hubbard (KMH) model on a zigzag ribbon of honeycomb lattice at a finite size via the weak-coupling renormalization group (RG) approach. In the noninteracting limit, the Kane-Mele (KM) model is known to support topological edge states where electrons show helical property with orientations of the spin and momentum being locked. The effective interedge hopping terms are generated due to finite-size effect. In the presence of an on-site Coulomb (Hubbard) interaction and the interedge hoppings, special focus is put on the stability of the topological edge states (TI phase) in the KMH model against (i) the charge and spin gaped (II) phase, (ii) the charge gaped but spin gapless (IC) phase, and (iii) the spin gaped but charge gapless (CI) phase depending on the number (even/odd) of the zigzag ribbons, doping level (electron filling factor) and the ratio of the Coulomb interaction to the interedge tunneling. We discuss different phase diagrams for even and odd numbers of zigzag ribbons. We find the TI-CI, II-IC, and II-CI quantum phase transitions are of the Kosterlitz-Thouless (KT) type. By computing various correlation functions, we further analyze the nature and leading instabilities of these phases. The relevance of our results for graphene is discussed.

  20. Cholera in Thomas Mann's Death in Venice.

    Science.gov (United States)

    Rütten, Thomas

    2009-01-01

    The article sets the cholera motif in Thomas Mann's famous novella Death in Venice against the historical context from which it partially originates. It is shown that this motif, while undoubtedly appropriated to serve Mann's own poetic ends, has a solid grounding in historical and autobiographical fact, thus blurring the boundaries between fact and fiction. The article illustrates the verifiable events of the outbreak of the Venetian cholera epidemic in May 1911, which Mann partly witnessed himself, during a holiday trip to Brioni and Venice, and partly heard and read about. It is established that Thomas Mann's account of the cholera in Venice in his novella is characterised by a rare and almost preternatural insightfulness into an otherwise murky affair that was marked by rumours, speculations and denials.

    In this paper we consider disjoint decomposition of algebraic and non-linear partial differential systems of equations and inequations into so-called simple subsystems. We exploit Thomas decomposition ideas and develop them into a new algorithm. For algebraic systems simplicity means triangularity, squarefreeness and non-vanishing initials. For differential systems the algorithm provides not only algebraic simplicity but also involutivity. The algorithm has been implemented in Maple.

  2. Religion and Ethics According to Thomas Aquinas

    Directory of Open Access Journals (Sweden)

    Povilas Aleksandravičius

    2011-04-01

    Full Text Available The aim of this paper is to show a common origin of religion and ethics in the philosophy of Thomas Aquinas. The concept of religion is closely related to metaphysics of being because it expresses the experience of a person facing the Source of being (God as Creator, actus essendi. By applying the aristotelian concept of justice and, at the same time, by pointing out its insufficiency to express the essence of religion, saint Thomas reveals the phenomenon of simultaneously metaphysical and religious desire. God is known as the Unknown, as absolutely Different, to which human being aspires. The structure of that phenomenon coincides with the structure of the origin of ethics: aspiration to the Source of being, imperceptible by the mind, forms the roots of natural good in the being of a person. With the help of synderese, which is one of the fundamental notions of ethics, saint Thomas clarifies the link that human being constantly maintains with his own ontological roots. The phenomenon of moral conscience, which links the deep heart of human being with the psychological level, is used as a basis to establish morals. Thus, common origin of religion and ethics occurs in the simultaneous real experience of the Source of being and of Good, experience which grants human being a particular purity called holiness.

God word deur Thomas die causa effiaiens en exemplaris genoem. Die verhouding tussen Skepper en geskape werklikheid is dus dié van oorsaak en gevolg. As gevolg van sy wetsidee word daar deur Thomas dus nie duidelik tussen Skepper en skepping onderskei nie, want skepping beteken volgens hom onder andere dat God iets goddeliks (die wet in die dinge lê.

    Chomsky's (1959) review of Verbal Behavior (Skinner, 1957) has been hailed as the most influential document in the history of psychology. Although many rejoinders to Chomsky's review have been published, their impact has been minimal. Moreover, Chomsky has not answered them in detail. To invite Chomsky to revisit a number of matters concerning the review, he was interviewed. The principal topics addressed by Chomsky were (a) historical factors associated with behaviorism after World War II; (b) circumstances surrounding the preparation of the review; (c) likely compatibility between formal and functional analyses of language; and (d) Chomsky's current point of view on aspects of the content of his review and on the evolution of behavior analysis.

The gauge theory localizes on generalized instanton solutions and is conjecturally equivalent to Donaldson-Thomas theory. We evaluate the partition function of the U(N) theory in its Coulomb branch on flat space by employing equivariant localization techniques on its noncommutative deformation. Geometrically this corresponds to a higher dimensional generalization of the ADHM formalism. This formalism can be extended to a generic toric Calabi-Yau.

    Full Text Available This article presents the relevancy of Aristotle’s hylemorphic ontology.Aristotle himself highlighted the importance and astonishing complexityof the problem of prime matter’s ontological status and he presenting thesolution in his doctrine of hylemorphism. As Saint Thomas Aquinasnoted, it is a crucial issue for philosophy because all four, hilemorfism,logic, physics and metaphysics, stand or fall depending on a correctunderstanding of the ontology of prime matter and of the kind of causalrelationship which exist between prime matter and substantial form ingenerable and corruptible substance.

  10. Thomas Young and the Rosetta Stone.

    2007-06-01

    Who deciphered the Rosetta Stone and the Egyptian hieroglyphs? The usual answer is Jean-François Champollion, beginning in 1822. But ever since that time, Egyptologists have debated the role of his rival, the polymath Thomas Young, the first person to publish a partially correct translation of the Rosetta Stone. A recent BBC television dramatisation rekindled the controversy by presenting Champollion as a 'lone genius' who succeeded independently of Young. While there is no doubt that Champollion deciphered the hieroglyphic script as a whole, the evidence suggests that Young's early detailed study of the Rosetta Stone created the conceptual framework that made possible Champollion's later breakthrough.

    Full Text Available Após retratar o surgimento da Escola histórica do pensamento político de Cambridge, o foco da análise é centrado no desenvolvimento de alguns dos pressupostos teóricos elaborados por um de seus mais expressivos cultores: Quentin Skinner. Sem me ocupar com a exposição de "modelos alternativos" de interpretação de textos ou com a análise das críticas dirigidas ao contextualismo linguístico, passo em revista apenas os elementos que compõem o cerne da teoria interpretativa de textos políticos, conforme formulada pelo historiador inglês. Nesse sentido, discuto os pressupostos que o autor, ainda hoje, parece julgar úteis àqueles que se ocupam em perceber, nos clássicos da política, as diferenças e as singularidades que apartam de nós sistemas de crenças e vocabulários normativos de sociedades políticas perdidas em tempos remotos.After depicting the birth of the Cambridge historical school of political thought, the focus of the analysis is placed on the development of some theoretical assumptions created by one of its most representative followers: Quentin Skinner. Unconcerned with the exposition of "alternative models" for text interpretations or with the analysis of the criticism directed to linguistic contextualism, this study revises the key elements of the interpretative theory of political texts, according to the English historian. In this sense, we discuss the assumptions that the author, even today, seems to deem useful to those who are interested in noticing in classic Politics the uniqueness which set us apart from the system of beliefs and normative vocabulary of the political societies lost in remote times.

    We place the Thomas-Fermi-von Weizsaecker model of atoms on a firm mathematical footing. We prove existence and uniqueness of solutions of the Thomas-Fermi-von Weizsaecker equation as well as the fact that they minimize the Thomas-Fermi-von Weizsaecker energy functional. Moreover, we prove the existence of bindings for two very dissimilar atoms in the frame of this model.

    Full Text Available The publication of the diplomatic correspondence of Sir Thomas Bodley online (Diplomatic Correspondence of Thomas Bodley, 1585 – 1597 offers a fine opportunity to study a text-type that is partly different from either business letters or personal correspondence. These texts lend themselves to be analysed from a sociopragmatic and discourse-analytic point of view, and this will be attempted in the paper by taking a closer look at the management of conflict, the degree of strength and directness of speech acts, and the ways in which social hierarchy is expressed. Several linguistic markers will be considered, in order to ascertain which elements can be seen as typically sensitive indicators in this particular text type, and how they relate to those found in other types of correspondence from the same period, which has been widely studied. In particular, the interplay between ‘diplomatic’ indirectness (also in the modern sense and direct reinforcement of personal bonds will be investigated; given the need to continuously express the element of personal trust, this type of correspondence seems particularly promising to analyse from this specific angle. Interesting insight can be gained by looking at the performing of specific acts or ‘moves’, for instance at the different levels of strength in directives, or at the linguistic means used to convey degrees of certainty in the reporting of information, both types of acts that figure prominently in these letters.

  13. Mixed State Geometric Phase from Thomas Rotations

    CERN Document Server

    Lévai, Peter

    2003-01-01

    It is shown that Uhlmann's parallel transport of purifications along a path of mixed states represented by $2\\times 2$ density matrices is just the path ordered product of Thomas rotations. These rotations are invariant under hyperbolic translations inside the Bloch sphere that can be regarded as the Poincar\\'e ball model of hyperbolic geometry. A general expression for the mixed state geometric phase for an {\\it arbitrary} geodesic triangle in terms of the Bures fidelities is derived. The formula gives back the solid angle result well-known from studies of the pure state geometric phase. It is also shown that this mixed state anholonomy can be reinterpreted as the pure state non-Abelian anholonomy of entangled states living in a suitable restriction of the quaternionic Hopf bundle. In this picture Uhlmann's parallel transport is just Pancharatnam transport of quaternionic spinors.

  14. Bakamjian-Thomas construction for quasistable states

    Energy Technology Data Exchange (ETDEWEB)

    Wickramasekara, S [Department of Physics, Grinnell College, Grinnell, IA 50112 (United States)

    2008-08-01

    As is evident from the multiple values listed in the particle data table for the mass and width of resonances, such as Z{sup 0}, {delta} and {rho}, defining these resonance parameters uniquely and unambiguously remains an open problem. This problem is ultimately rooted in the absence of a state vector description of a resonance that has definite properties under spacetime transformations. We show that there exist irreducible representations of the causal Poincare semigroup that provide such a state vector description to resonances, leading to well-defined mass and width parameters. Generated by an interaction-incorporating Poincare algebra and characterized by the complex S-matrix pole position and spin of the resonance, these representations synthesize the Bakamjian-Thomas construction of relativistic interactions and the S-matrix description of resonances.

  15. Optical Thomas-Reiche-Kuhn Sum Rules

    Science.gov (United States)

    Barnett, Stephen M.; Loudon, Rodney

    2012-01-01

    The Thomas-Reiche-Kuhn sum rule is a fundamental consequence of the position-momentum commutation relation for an atomic electron and it provides an important constraint on the transition matrix elements for an atom. Analogously, the commutation relations for the electromagnetic field operators in a magnetodielectric medium constrain the properties of the dispersion relations for the medium through four sum rules for the allowed phase and group velocities for polaritons propagating through the medium. These rules apply to all bulk media including the metamaterials designed to provide negative refractive indices. An immediate consequence of this is that it is not possible to construct a medium in which all the polariton modes for a given wavelength lie in the negative-index region.

    2012-01-01

    Thomas K. Jeffers has made many significant contributions to our understanding of the biology of the parasite Eimeria, the cause of coccidiosis in poultry. His work has had direct practical application for the control of this widespread disease. Topics discussed include Jeffers' pioneering work concerned with genetics of the host response to infection, the nature of biological and immunological intraspecific variation, drug resistance and discovery, field surveys of resistance, and his most recognized achievement-the demonstration that the lifecycle of coccidia may be altered by artificial selection. Parasites so modified are attenuated but retain their immunogenicity, a discovery that has led to the development of live vaccines that are inherently non-pathogenic. This article provides a brief biography and describes the contributions that Jeffers has made to our knowledge of coccidiosis.

  18. Thomas Bowdler: censor, philanthropist, and doctor.

    Science.gov (United States)

    Jellineck, E H

    2001-09-29

    A recent biography of the physician William Osler credits him with having generated a verb, to "oslerize", as a synonym for euthanasia. Actually, Osler had been mocking his own impending senescent uselessness at the time of his move from Baltimore to Oxford. That neologism did not last. Two earlier doctors who did make it to the dictionaries in a verbally eponymous way were F A Mesmer and Thomas Bowdler, and Bowdler, at least, would not have liked the recognition. The first use of the verb to "bowdlerise" seems to have been in 1836, with a reference to "names in the writings of the apostles which modern ultrachristians would probably have Bowdlerized". However, Bowdler is better remembered for his cleaning up of the plays of Shakespeare.

    2010-01-01

    Thomas Schwencke (1694-1767) was Professor of Anatomy and Surgery and Lecturer in Obstetrics at the Surgical School in The Hague, the Netherlands. In 1743 he published the very first textbook on haematology. Furthermore, he described his observations on the variolation of smallpox, and published the design of a new obstetric instrument. Schwencke was physician of the city of The Hague and also physician at the court of the princes van Nassau-Weilburg. In 1765 Princess Caroline of Nassau-Weilburg invited the young Wolfgang Amadeus Mozart to perform concerts. During his Dutch tour the young Mozart fell seriously ill, probably from typhoid fever. At the request of the court Mozart was seen for a second opinion and thereafter successfully treated by Schwencke. Mozart could continue his concert tour and Schwencke's reputation as Mozart's physician was established.

    Near-bottom magnetic field measurements made by the submersible Nautile during the 1992 Kanaut Expedition define the cross-sectional geometry of magnetic polarity reversal boundaries and the vertical variation of crustal magnetization in lower oceanic crust exposed along the Kane Transform Fault (TF) at the northern boundary of the Kane Megamullion (KMM). The KMM exposes lower crust and upper mantle rocks on a low-angle normal fault that was active between 3.3 Ma and 2.1 Ma. The geometry of the polarity boundaries is estimated from an inversion of the submarine magnetic data for crustal magnetization. In general, the polarity boundaries dip away from the ridge axis along the Kane TF scarp, with a west dipping angle of ~45° in the shallow (isotherms and isochrons. We also test the effects of the rotation of this isotherm structure and/or footwall rotation and find that the magnetic polarity boundary geometry is not sensitive to these directional changes.

  6. A "Kane's Dynamics" Model for the Active Rack Isolation System Part Two: Nonlinear Model Development, Verification, and Simplification

    Beech, G. S.; Hampton, R. D.; Rupert, J. K.

    2004-01-01

    Many microgravity space-science experiments require vibratory acceleration levels that are unachievable without active isolation. The Boeing Corporation's active rack isolation system (ARIS) employs a novel combination of magnetic actuation and mechanical linkages to address these isolation requirements on the International Space Station. Effective model-based vibration isolation requires: (1) An isolation device, (2) an adequate dynamic; i.e., mathematical, model of that isolator, and (3) a suitable, corresponding controller. This Technical Memorandum documents the validation of that high-fidelity dynamic model of ARIS. The verification of this dynamics model was achieved by utilizing two commercial off-the-shelf (COTS) software tools: Deneb's ENVISION(registered trademark), and Online Dynamics Autolev(trademark). ENVISION is a robotics software package developed for the automotive industry that employs three-dimensional computer-aided design models to facilitate both forward and inverse kinematics analyses. Autolev is a DOS-based interpreter designed, in general, to solve vector-based mathematical problems and specifically to solve dynamics problems using Kane's method. The simplification of this model was achieved using the small-angle theorem for the joint angle of the ARIS actuators. This simplification has a profound effect on the overall complexity of the closed-form solution while yielding a closed-form solution easily employed using COTS control hardware.

On the one hand, the $\\mathbb{Z}_2$ invariant can be formulated in terms of the Berry connection and the Berry curvature of the Bloch bundle of occupied states over the Brillouin torus. On the other, using techniques from the theory of bundle gerbes it is possible to provide an expression for $\\mathrm{FKM}$ containing the square root of the Wess-Zumino amplitude for a certain $U(N)$-valued field over the Brillouin torus. We link the two formulas by showing directly the equality between the above mentioned Wess-Zumino amplitude and the Berry phase, as well as between their square roots. An essential tool of independent interest is an equivariant version of the adjoint Polyakov-Wiegmann formula for fields $\\mathbb{T}^2 \\to U(N)$, of which we provide a p...

    We establish a connection between two recently proposed approaches to the understanding of the geometric origin of the Fu-Kane-Mele invariant FKMin Z_2 , arising in the context of two-dimensional time-reversal symmetric topological insulators. On the one hand, the Z_2 invariant can be formulated in terms of the Berry connection and the Berry curvature of the Bloch bundle of occupied states over the Brillouin torus. On the other, using techniques from the theory of bundle gerbes, it is possible to provide an expression for FKM containing the square root of the Wess-Zumino amplitude for a certain U(N)-valued field over the Brillouin torus. We link the two formulas by showing directly the equality between the above-mentioned Wess-Zumino amplitude and the Berry phase, as well as between their square roots. An essential tool of independent interest is an equivariant version of the adjoint Polyakov-Wiegmann formula for fields T^2 → U(N) , of which we provide a proof employing only basic homotopy theory and circumventing the language of bundle gerbes.

He was senior research investigator at the Blackett Laboratory and Emeritus Professor of Theoretical Physics at Imperial College, London. He made seminal contributions to our current understanding of symmetries and symmetry breaking in the Standard Model of particle physics. He was among those who, in 1964, proposed the mechanism of spontaneous symmetry breaking in gauge theories, together with G. Guralnik and C. Hagen in the autumn of that year, following the papers by R. Brout and F. Englert and by P. Higgs. When this new understanding was incorporated into a model proposed by S. Glashow in 1961, it led to the first formulations of the Standard Model by S. Weinberg and A. Salam. Kibble deepened our under...

  10. Thomas Edison’s Poetry Machine

    Directory of Open Access Journals (Sweden)

    Matthew Rubery

    2014-04-01

    Full Text Available The tradition of spoken-word recording began with Thomas Edison’s invention of the phonograph. Hence, this article makes the case that 1878 is a more important year to the history of literature than has yet been recognized for its experiments with verse and sound-recording technology. Although the tinfoil phonograph’s first decade has been well documented by media historians, literary critics have singled out 1888 as the noteworthy year since that is when Edison’s improved phonograph made it possible to record prominent figures including Alfred Tennyson and Robert Browning. Taking Edison’s original tinfoil phonograph as an alternative starting point reveals how the 1878 phonograph demonstrations, despite technological limitations, undertook acoustic experiments that enabled audiences to discern new forms of meaning, pleasure, and pathos in even the most well-known material. The recordings considered here include ‘Mary Had a Little Lamb’ as well as scripts by Tennyson, Caroline Norton, Edgar Allan Poe, Shakespeare, and others. Such recitals illustrate the extent to which Edison’s talking machine influenced the reception of texts while at the same time giving rise to performances unheard of in previous cultures.

    Professor Thomas Lehner is one of the most distinguished oral and dental researchers to have come out of the UK. Over the past 40 years, he has made an astonishing number of discoveries which have had an impact on our understanding of the pathogenesis of a variety of mucosal diseases. He has consistently practiced both basic and clinical research and built an integrated group of clinical and non-clinical researchers, which allowed him easy transition from the laboratory to the clinic. Tom Lehner was among the early scientists studying mucosal immunology, initially exploring oral diseases, with special emphasis on the immunobiology of Streptococcus mutans, leading to active and passive vaccination against dental caries. He was the first to demonstrate cellular immunity as the immunopathological basis of periodontal diseases, recurrent aphthous stomatitis, and candidiasis. Over the past 20 years, his expertise in mucosal immunobiology has been applied to the immunology of HIV/SIV infections. His seminal contributions include regional innate mucosal immunity, prevention of SIV infection in macaques by secretory IgA antibodies, up-regulation of CC chemokines, and the first demonstration of protective CCR5 antibodies. Arguably, his leadership, his students, and the establishment of immunology applied to oral mucosal diseases will be his greatest legacy. His contributions continue unabated.

  12. Thomas Wolsey on stage and screen

    Full Text Available Cardinal Thomas Wolsey, lord chancellor of England from 1515 to 1529, has played no small part in the many literary, historical and dramatic retellings of the reign of King Henry VIII. This article presents the first extended analysis of the way in which Wolsey has been represented by playwrights and, later, film and television writers during the years from his death in 1530 through the present. The article demonstrates that by the middle of the 16th century, two competing narratives about Wolsey had become entrenched historiographically, and nearly all subsequent accounts borrow substantially from the narratives of either Edward Hall (1550 or George Cavendish (1554–1558. How successive playwrights and screenwriters balanced the cardinal’s two archetypal personae has often depended, in no small part, on the concerns of their own day. In the 21st century, readings of the cardinal as crafty rather than callous, unlucky rather than unprincipled, have become more common, and with them have come more sympathetic portrayals of a traditional Tudor villain.

  13. Thomas Kuhn as a Historian of Science

    Brush, Stephen G.

    Thomas S. Kuhn (1922-1996) exerted a strong force on intellectual discourse in the last third of the 20th century, by the publication of a book only 200 pages long. Why did Kuhn's publications in his own primary field, history of science, have so little impact on that field? Was The Structure of Scientific Revolutions so successful in accelerating the trend toward social history of science that his own internalist work seemed outmoded? Kuhn wrote incisive articles on a wide range of topics including Robert Boyle and structural chemistry, energy conservation as an example of simultaneous discovery, the Cagnard engine, and the historiography of science, as well as a book on the Copernican Revolution; they are rarely cited by historians of science. His most important historical contribution in later years was in the history of quantum theory; he led a project to collect and preserve source materials, and published a monograph on the origin of the quantum hypothesis. Why does he receive almost no recognition for his remarkable work on the history of quantum physics? Does everyone still believe (in spite of Kuhn) that Planck introduced a physical quantum discontinuity in 1900?

  15. Thomas Piketty’s capitalism revisited

    Directory of Open Access Journals (Sweden)

    Milovanović Milić

    2015-01-01

    Full Text Available Thomas Piketty’s international best selling Capital in the Twenty-First Century lays out his theory of a long-run rise in income inequality under capitalism. It is written as a manifesto urging reintegration of social sciences. A number of reviewers judged it on ideological grounds, labeling it either as a revolution in economic thinking, or dismissing it offhandedly. Piketty’s theory of rising inequality is based on the two Fundamental Laws of Capitalism, developed after the Solow growth model. However, this model is inconsistent with Piketty’s own characterization of modern capitalism. Moreover, his sole justification for the constant discrepancy between rate of return and rate of income growth (r > g is based on the high elasticity of substitution between capital and labor. However, that is just one factor that can have an influence on factor income shares. By failing to offer a consistent theory of rising inequality, his piece can hardly be considered as a useful founding stone for a new social science.

    A new semi-classical Thomas-Fermi scheme is advanced that is able to extend the range of validity of the concomitant reduced one-body density beyond the classical turning points. The approach is based upon information theory concepts and employs as informational input just a few standard Thomas-Fermi mean values. One-dimensional examples show that the present technique considerably improves upon the traditional one. (orig.)

    The article attempts to clarify an important aspect of St. Thomas Aquinas’s theory of human action, namely to show these acts of man which are immediately caused by the will. According to some contemporary philosophers, the acts of the will are limited to those of trying or of intending. Do they exhaust the whole possibility of the will to act? The author seeks to answer this question basing his considerations on the analysis of the Summa Theologiae by St. Thomas Aquinas.

    We describe a pilot study to investigate whether drawing "Thomas the Tank Engine" could be as effective a measure of developmental progress as the Goodenough-Harris Draw A Man test against the ThOMAs test (The Other Means of Assessment), with internal validation. The study included 95 children aged between 3 and 11 years of age, including a subgroup of 13 children with registered special needs from community and general pediatric clinics within Birmingham, UK, as a means of validation. There was no significant evidence that ThOMAS was either culturally or sex biased. Using regression analysis, nine items were found to correlate highly with actual age, and their total score gave a correlation of 0.563 with age. Adding further items did not increase this. After being converted into age-standardized scores, ThOMAS was as sensitive and specific as the Draw A Man test, and more so above a defined age-standardized threshold. This pilot study suggests that drawing Thomas the Tank Engine would appear to be as sensitive and specific a means of identifying children with special needs as the Goodenough-Harris Draw A Man test. The relatively small sample size means that further research is necessary to further define the age standardizations and to refine the ThOMAs test.

Taking a set of simulated data and a set of real images as the experimental subject, four existing methods are taken to compare with Skinner-Ransac. The results show that the performance of Skinner-Ransac is better than the other methods.

Come avviene la trasfigurazione del quotidiano nel mondo finzionale? Come si svolge il processo di identificazione dell'io nell'opera? Lo studioso rintraccia il fondamento di tale processo nella non coincidenza di principio tra io e vita, quindi nella facoltà del lettore di accogliere e riconoscere il senso dell'opera. Un senso che tuttavia non si palesa una volta per tutte nella sua interezza e trasparenza, ma che diviene oggetto di continuo dialogo fra i lettori, un senso quindi affidato alle loro cure.During the opening lecture of his course at Collège de France, held on April 6th 2006, Thomas Pavel talks about the emotional and ethical aspects of reading and about «completely surrending» to literature.

The scholar traces the origin of this process to the radically different principles governing ego and life. Because of this, the reader is able to grasp and understand the real meaning of the book.

    Directory of Open Access Journals (Sweden)

    Sara Soncini

    2010-10-01

    Full Text Available Death is an overarching presence in Sarah Kane's dramatic universe, peopled by characters charging towards death, and usually encountering it in scenes of Grand Guignol excess and grotesque violence. Death is ambivalently presented as the only escape from the nightmare of living and, at the same time, as that which makes living a nightmare; as the moment of "complete sanity and humanity" in which "everything suddenly connects", and as the ultimate, irrevocable and unredeemable act of self-annihilation. Following Kane's turn towards a more poetic form of drama, in her last two plays this discourse of death is handed over to the words nameless characters or unidentified voices who are likewise engaged in a long, painful quest for selfhood pivoting on the awareness of mortality and the simultaneous dread of and longing for death it engenders. This essay focuses on the ritual quality of the death scenes and/or narratives that crowd Kane's drama. Throughout her work, dying is never an easy, straightforward business, but rather a long, complicated, and at times frustrating mise en scène which also entails rehearsing a repertory of traditional rituals and, once their shortcomings become apparent, devising and testing new ones. The amount of theatricality involved in the art of dying is foregrounded through a web of intertextual references to other literary and/or dramatic sources; this dialogue ties in with a self-reflexive probing of the theatre's ability to provide a ritual that will be capable of "contain[ing] the horror" by supplying a formal framework to express, embody and experience death collectively.

    2007-12-01

    The astronomy community lost a good friend when Tom Metcalf was killed in a skiing accident on Saturday, 7 July 2007, in the mountains near Boulder, Colorado. Tom was widely known for prolific work on solar magnetic fields, hard-X-ray imaging of solar flares, and spectral line diagnostics. He was often characterized as "one of the nicest guys in science." Born October 5, 1961 in Cheverly, Maryland, to Fred and Marilyn, Thomas R. Metcalf joined his sister, Karen, two years his elder, in a close family that loved sailing, inquisitiveness, and the natural world. Sibling rivalry (usually a Tonka truck intruding on Barbie's sub-table "castle") melted when Tom and Karen collaborated on elaborately engineered room-sized blanket-forts. Tom confidently signed up at age of three to crew for his family's sailboat; when the family moved to California in 1966, as Tom's father took a Professor of Mathematics position at the University of California Riverside, Tom's love for sailing was well-established. Week-long cruises or short trips in the harbor were all fun; when school friends came aboard, it was even better--if "only slightly too crowded" from the adults' points of view. Tom's introduction to astronomy began one cold, very clear, December night in the early 1970s, on a family camping trip to Death Valley. The "Sidewalk Astronomers of San Francisco" had lined the sidewalk near the visitors' center with all sorts of telescopes for public viewing. Soon after, Tom and his boyhood friend Jim O'Linger were building their own scopes, attending "Amateur Telescope Makers" conferences, and Tom was setting up his scope on a sidewalk for public viewing. In 1986, Tom set up his telescope on the bluffs above Dana Point Harbor, and gave numerous strangers a stunning view of Halley's Comet. His interest in physics and mathematics became evident during Tom's last years in high school (Poly High in Riverside), and as a senior he qualified to take freshman Physics at the University of

    Over the years, I've daydreamed about stealing a Vermeer, a Picasso, or Rembrandt. It tickles me, as much as watching the reboot of The Thomas Crown Affair. Why is it, do you suppose, so much fun to think about stealing a world renowned piece off the wall of a major metropolitan museum? Is it the romantic thoughts of getting away with it, walking past infrared detectors, and pressure sensors ala Indiana Jones with the sack of sand to remove the idol without triggering the security system? Is it the idea of snatching items with such fantastic prices, where the romance of possessing an item of such value is less intoxicating than selling it to a private collector for it to never be seen again? I suspect others share my daydreams as they watch theater or hear of a brazen daylight heist at museums around the world, or from private collections. Though when reality sets in, the mind of the security professional kicks in. How could one do it, why would one do it, what should you do once it's done? The main issue a thief confronts when acquiring unique goods is how to process or fence them. They become very difficult to sell because they are one-of-a-kind, easy to identify, and could lead to the people involved with the theft. The whole issue of museum security takes up an ironic twist when one considers the secretive British street artist 'Banksy'. Banksy has made a name for himself by brazenly putting up interesting pieces of art in broad daylight (though many critics don't consider his work to be art) on building walls, rooftops, or even museums. I bring him up for a interesting take on what may become a trend in museum security. In March of 2005, Banksy snuck a piece of his called 'Vandalized Oil Painting' into the Brooklyn Museum's Great Historical Painting Wing, plus 3 other pieces into major museums in New York. Within several days, 2 paintings had been torn down, but 2 stayed up much longer. In his home country of the UK, a

Ce qui l'amène à faire de la théorie des actes de la parole l'axe de son projet méthodologique. Si l'on suit l'approche que Paul Ricoeur entreprend dans la phénoménologie de l'écrit, les différences entre ces deux types de communication s'imposent et, par conséquent, les impropriétés provoquées par l'équivalence adoptée par Skinner. On voit pourquoi l'approche critique à la méthodologie de l'auteur anglais est plus productive et systématique que la plupart des critiques qu'on lui a adressées, y compris celles inspirées de la pensée de Hans-Georg Gadamer.

    Vivien Thomas (1910-1985) was an African-American scientist, pioneer, and renowned educator. Thomas's contributions to cardiovascular surgery were unequivocal, and yet it was only after his death that he gained more widespread recognition. Thomas's more notable work involves aiding in the discovery of the cause of traumatic shock, designing and guiding the first operation to treat Tetralogy of Fallot, carrying out the first atrial septectomy, and helping develop the electrical defibrillator. Thomas struggled amidst the adversities of racism and the Great Depression (1929-1941), armed merely with a high school degree. Nevertheless, his genius and determination eventually led him to receive an honorary doctorate from John Hopkins University. His story inspired the creation of the award winning PBS documentary in 2003 Partners of the Heart and also the 2004 Emmy Award-winning HBO film Something the Lord Made. This article will aim to provide an overview to the more notable events in Thomas's amazing tale, with a particular focus on his work on the Tetralogy of Fallot.

  20. William Osler and Seymour Thomas, "the boy artist of Texas".

    Critics consider the 1908-1909 portrait of William Osler by S. Seymour Thomas the best of six oil-on-canvas portraits of Osler done from life, including those by the more acclaimed US artists John Singer Sargent and William Merritt Chase. Osler called it "the best pictorial diagnosis I have ever seen" and told Thomas "I am at your service." A reappraisal of Seymour Thomas explains why his portrait makes us feel much as the artist did in Osler's presence, which is the original English-language definition of "empathy." Thomas told his subject that "I feel that you can look clear through me and see the wall on the other side." The intensity of Osler's gaze affects us similarly. The portrait satisfied Osler, but his wife, Grace Revere Osler, never warmed to it, perhaps because it depicts so clearly a highly focused, agenda-driven man. Helen Thomas used the portrait to promote her husband's business, and, after a tortuous history, the portrait eventually returned to Oxford University, where it now hangs inconspicuously in the Radcliffe Science Library.

    precedents and thought in a unique legal market in which ideas drawn from Islamic law, civil law and common law can intermingle and blend. It is not surprising therefore to see that this new publication will be dedicated to the subject of international law, both public and private. Its laudable aim is to promote legal discourse around the world, and to promote a wider international understanding of contemporary legal issues for the common benefit. As an open access, bilingual journal, addressing topics concerning any jurisdiction, I hope it will reach a wide audience, and fulfil its aim of promoting understanding between different cultures. I am sure that the journal will not only benefit Qatar’s legal community by advancing academic and practice-based legal discussion. I am also confident that it will stimulate thought in the global legal community at large. May I wish it every success and a long life. Michael Thomas CMG QC

    2004-12-01

    Thomas M. Donahue, one of the nation's leading space and planetary scientists and a pioneer of space exploration, died Saturday October 16, 2004, from complications following heart surgery. The Edward H. White II Distinguished University Professor of Planetary Science at the University of Michigan, Tom shaped space exploration through his scientific achievements and policy positions. His work started with the first use of sounding rockets following World War II and continued for almost 60 years. Tom was born in Healdton, Oklahoma on May 23, 1921 to Robert Emmet and Mary (Lyndon) Donahue. His father was a plumber in the oil fields when Tom was born (Healdton OK was an oil town) and worked as a plumber in Kansas City for a time. Tom grew up in Kansas City, graduating in 1942 from Rockhurst College in that city with degrees in classics and physics. His graduate work in physics at Johns Hopkins University was interrupted by service in the Army Signal Corps. He obtained his PhD degree in atomic physics from Hopkins in the fall of 1947. After three years as a post-doctoral research associate and assistant professor at Hopkins, Tom joined the University of Pittsburgh Physics Department in 1951. At Pittsburgh he organized an atomic physics and atmospheric science program that led to experimental and theoretical studies of the upper atmosphere of the Earth and other solar system planets with instruments flown on sounding rockets and spacecraft. He became Professor of Physics in 1959 and eventually Director of the Laboratory for Atmospheric and Space Sciences and the Space Research Coordination Center at the University. In 1960 he spent a sabbatical year on a Guggenheim Fellowship at the Service d'Aeronomie in Paris, which began collaborations with French colleagues that flourished for more than 40 years. In 1974 he became the Chairman of the Atmospheric and Oceanic Science Department, University of Michigan, a position he held until 1981. In 1986, he was named the Henry

    Full Text Available The article attempts to clarify an important aspect of St. Thomas Aquinas’s theory of human action, namely to show these acts of man which are immediately caused by the will. According to some contemporary philosophers, the acts of the will are limited to those of trying or of intending. Do they exhaust the whole possibility of the will to act? The author seeks to answer this question basing his considerations on the analysis of the Summa Theologiae by St. Thomas Aquinas.

  6. Cohomological orientifold Donaldson-Thomas invariants as Chow groups

    CERN Document Server

    Franzen, Hans

    2016-01-01

    We establish a geometric interpretation of orientifold Donaldson-Thomas invariants of $\\sigma$-symmetric quivers with involution. More precisely, we prove that the cohomological orientifold Donaldson-Thomas invariant is isomorphic to the rational Chow group of the moduli space of $\\sigma$-stable self-dual quiver representations. As an application we prove that the Chow Betti numbers of moduli spaces of stable $m$-tuples in classical Lie algebras can be computed numerically. We also prove a cohomological wall-crossing formula relating semistable Hall modules for different stabilities.

    The Thomas Range is world-famous for its production of topaz Al2SiO4(F,OH)2, occurring in lithophysal cavities in rhyolite. Topaz Valley, at the southern end of the range, is perhaps the single most famous locality. While fine-quality, sherry-orange crystals to 5 cm or more in length occur at various localities, pale to medium pink crystals were first reported from the Thomas Range in 1934. The cause of the unusual coloration, unknown for 60 years, is now believed to be substitution of Mn3+ ?? Fe3+ for Al3+. -Authors

    Freeborn, Todd J.; Maundy, Brent; Elwakil, Ahmed

    In this paper we propose the use of fractional capacitors in the Tow-Thomas biquad to realize both fractional lowpass and asymmetric bandpass filters of order 0function approximation of the fractional capacitors. MATLAB and PSPICE simulations of first order fractional-step low and bandpass filters of order 1.1, 1.5, and 1.9 are given as examples. Experimental results of fractional low pass filters of order 1.5 implemented with silicon-fabricated fractional capacitors verify the operation of the fractional Tow-Thomas biquad.

    Thomas J. Ahrens, a leader in the use of shock waves to study planetary interiors and impact phenomena, died at his home in Pasadena, California on November 24, 2010, at the age of 74. He was the California Institute of Technology's Fletcher Jones Professor of Geophysics, formally emeritus since 2005 but professionally active to the end. Tom was a pioneer in experimental and numerical studies of the effects of hypervelocity impact, arguably the most important geophysical process in the formation, growth and - in many cases - surface evolution of planets. As a professor at Caltech, he established the foremost university laboratory for shock wave experiments, where students and research associates from around the world pursued basic research in geophysics, planetary science and other disciplines. Previously, high-pressure shock experiments were primarily conducted in national laboratories, where they were initially associated with development of nuclear weapons. The shock wave laboratory at Caltech was noted for key measurements addressing major questions in planetary geophysics. Equation-of-state studies on silicate melts showed that magma deep in Earth's mantle could be denser than the coexisting crystals, implying downward transport of melts (and associated heat) rather than the upward eruption of lavas observed in volcanic regions at Earth's surface. Shock-melting experiments on iron at pressures of Earth's core provide a crucial constraint on the temperature at the center of our planet. And studies of hydrous, carbonate and sulphate minerals under shock compression document how climate-altering molecules can be released by major impacts, such as the K/T event associated with the most recent mass extinction of biota in Earth history. In addition, Tom was a leader in numerical simulation of cratering, bringing the most recent laboratory measurements into the modeling of planetary impacts. Tom's training was in geophysics and applied experimental physics, as

    We show that the partition functions which enumerate Donaldson-Thomas invariants of local toric Calabi-Yau threefolds without compact divisors can be expressed in terms of specializations of the Schur measure. We also discuss the relevance of the Hall-Littlewood and Jack measures in the context of BPS state counting and study the partition functions at arbitrary points of the Kaehler moduli space. This rewriting in terms of symmetric functions leads to a unitary one-matrix model representation for Donaldson-Thomas theory. We describe explicitly how this result is related to the unitary matrix model description of Chern-Simons gauge theory. This representation is used to show that the generating functions for Donaldson-Thomas invariants are related to tau-functions of the integrable Toda and Toeplitz lattice hierarchies. The matrix model also leads to an interpretation of Donaldson-Thomas theory in terms of non-intersecting paths in the lock-step model of vicious walkers. We further show that these generating functions can be interpreted as normalization constants of a corner growth/last-passage stochastic model.

  11. Obituary: Thomas Gold, 1920-2004

    Science.gov (United States)

    Dermott, Stanley F.

    2004-12-01

    Thomas "Tommy" Gold died of heart disease at Cayuga Medical Center, Ithaca NY on 22 June 2004 at the age of 84. He will be remembered as one of the most interesting, dynamic and influential scientists of his generation. Tommy's paradigm-changing ideas in astronomy and planetary science, while original and bold, were also highly controversial. With his radical work on the origin of natural gas and petroleum, the controversy is likely to continue. Tommy was born in Vienna, Austria on 22 May 1920, moving with his family to Berlin at age 10 and then, after the rise of Hitler in 1933, to England. His parents were Josephine (nee Martin) and Maximillian Gold, a successful steel magnate. Tommy was educated at Zuoz College in Switzerland where he became an expert skier and developed an athletic prowess that he maintained throughout his life, winning a NASTAR gold medal for skiing at the age of 65. He studied Mechanical Sciences at Trinity College, Cambridge, but much to his disgust his education was interrupted because of internment by the British as a suspected enemy alien. That unfortunate period (I remember him saying to me "Can you believe the stupidity, interring people like me who had fled from Nazi Germany?") had one good outcome: on his first night in camp he met Hermann Bondi who had an important influence on his early development as a scientist. They were both born in Vienna, their parents knew each other, and they were fellow students at Trinity, but this was their first meeting. On release, he went immediately into top-secret radar research for the British Admiralty, working as a team with Bondi and Fred Hoyle in a farm cottage in Dunsfold, Surrey. Tommy's first published research, which was a Nature paper with R.J. Pumphrey in 1947, was not in astronomy but physiology. He applied his engineer's understanding of positive feedback to develop and test a resonance model for how the human ear determines pitch. His conclusion that pitch discrimination occurs

  14. The formulation of dynamical contact problems with friction in the case of systems of rigid bodies and general discrete mechanical systems—Painlevé and Kane paradoxes revisited

    Science.gov (United States)

    Charles, Alexandre; Ballard, Patrick

    2016-08-01

    The dynamics of mechanical systems with a finite number of degrees of freedom (discrete mechanical systems) is governed by the Lagrange equation which is a second-order differential equation on a Riemannian manifold (the configuration manifold). The handling of perfect (frictionless) unilateral constraints in this framework (that of Lagrange's analytical dynamics) was undertaken by Schatzman and Moreau at the beginning of the 1980s. A mathematically sound and consistent evolution problem was obtained, paving the road for many subsequent theoretical investigations. In this general evolution problem, the only reaction force which is involved is a generalized reaction force, consistently with the virtual power philosophy of Lagrange. Surprisingly, such a general formulation was never derived in the case of frictional unilateral multibody dynamics. Instead, the paradigm of the Coulomb law applying to reaction forces in the real world is generally invoked. So far, this paradigm has only enabled to obtain a consistent evolution problem in only some very few specific examples and to suggest numerical algorithms to produce computational examples (numerical modeling). In particular, it is not clear what is the evolution problem underlying the computational examples. Moreover, some of the few specific cases in which this paradigm enables to write down a precise evolution problem are known to show paradoxes: the Painlevé paradox (indeterminacy) and the Kane paradox (increase in kinetic energy due to friction). In this paper, we follow Lagrange's philosophy and formulate the frictional unilateral multibody dynamics in terms of the generalized reaction force and not in terms of the real-world reaction force. A general evolution problem that governs the dynamics is obtained for the first time. We prove that all the solutions are dissipative; that is, this new formulation is free of Kane paradox. We also prove that some indeterminacy of the Painlevé paradox is fixed in this

    The lobectomy for carcinoma of the lung performed by William E. Adams in 1946 on Thomas Mann, author of the tuberculosis saga The Magic Mountain, deserves to be added to Harold Ellis's series of "historically famous operations." This lobectomy, by which the surgeon cured his far more famous patient, was only one episode in his 40 eventful years as Chicago's leading pioneer in early thoracic surgery. The historic case is well documented by preoperative, operative, and pathology reports obtained through the courtesy of still-living witnesses and associates, friends of the author. Thomas Mann died 9 years later of an aortoiliac rupture at the University Hospital in Zurich. At autopsy no local recurrence or distal metastasis was found.

    1999-01-01

    Soon after his 80th birthday in June 1955 celebrated in Kilchberg near Zürich Thomas Mann developed a swollen and painful left leg during his vacation on the seashore of Holland. The diagnosis of "thrombophlebitis" was made by Mülders from Leiden and confirmed by Wilhelm Löffler in Zürich. To the surprise of the treating doctors an irreversible shock occurred, when the famous poet and Nobel laureate was improving. The pathological diagnosis (Christoph Hedinger) was perforation of an iliac artery aneurysm on the left side with extensive retroperitoneal hematoma, compression and thrombosis of the iliac vein. Because of lacking apparative techniques correct intra vitam diagnosis was not yet possible in 1955, and life saving vascular surgery was available only shortly later. It is described how Thomas Mann himself experienced his last illness. His astonishing medical knowledge is illustrated by examples dealing with vascular medicine. A summary of his last year of life is given.

    Full Text Available This article puts forward that according to Scottish philosopher, Thomas Reid (1710-1796, justice must be understood as a moral virtue of a natural kind among human beings, or as a matter of species regarding them; not as an artificial or a conventional virtue, which is a product of human collectivities or a matter of sociability in human beings. However, the article proposes as well that in his reflections on justice, Thomas Reid held an arguable notion of property, as the ownership of riches basically distributable or apportionable, but not as one of the goods that are mainly produced or generated, as his contemporaries David Hume and Adam Smith stated it.

    "Losing Thomas & Ella" presents a research comic about one father's perinatal loss of twins. The comic recounts Paul's experience of the hospital and the babies' deaths, and it details the complex grieving process afterward, including themes of anger, distance, relationship stress, self-blame, religious challenges, and resignation. A methodological appendix explains the process of constructing the comic and provides a rationale for the use of comics-based research for illness, death, and grief among practitioners, policy makers, and the bereaved.

    This study provides an extensive examination of the work of Thomas Kinsella by addressing the fundamental question of form which his poetry presents. There are two phases in Kinsella’s writing: one contains poems written for the most part in conventional stanzaic forms; the other utilises forms less bounded by inherited formal convention.

  3. [Medical practice in the thought of Thomas Aquinas].

    Fagiolo, Enzo

    2007-01-01

    In the works of St. Thomas Aquinas there are many examples of medical practice, in the discussion of philosophical and theological questions. St. Thomas asserts that like the doctor causes the recovery of the patient, although it is the power of nature to perform, so does the teacher with his student; the teacher raises the knowledge in the student, even if it is the own reason to act. Like the patient can be recovered only by natural force or by this force with the help of the doctor, in the same way, knowledge can be achieved only through the natural reason of the student or with the help of the teacher. To define the relationship between the desired aim and the means to achieve it, St. Thomas suggests a fundamental principle of medical ethics. The doctor, which is minister of nature, if has no limit wishing the recovery of the patient, must have a measure in relation to the means used to obtain that goal. In fact, he must try to cure the patient in the best way he can, not using the "strongest" drug; in fact, the drug is not the aim but it is only one of the means to obtain health.

    To highlight the contributions from the University of Chicago under the leadership of Dr David B. Skinner to the understanding of gastroesophageal reflux disease (GERD) and its complications. The invention of the esophagoscope confirmed that GERD was a premorbid condition. The medical world was divided between those who believed in a morphological lower esophageal sphincter (LES) and those who did not. Those who did not believe attempted to rearrange the anatomy of the foregut organs to stop reflux with minimal success. The discovery of the LES focused attention on the sphincter as the main deterrent to reflux and the hope that measurement of a low LES pressure would mark the presence of GERD. This turned out not to be so. In July 1973, with this history of confusion, Dr Skinner at the age of 36 assumed the chair of surgery at the University of Chicago. The publications of the University of Chicago's esophageal group were collected from private and public (PubMed) databases, reviewed, and seminal contributions selected. Twenty-four-hour esophageal pH monitoring led to the understanding of the LES, its contribution to GERD, and the complication of Barrett's esophagus. The relationship of Barrett's to adenocarcinoma was clarified. The rising incidence of esophageal adenocarcinoma led to contributions in the staging of esophageal cancer and its treatment with an en bloc resection. Ten years after the death of Dr Skinner, we can appreciate the monumental contributions to benign and malignant esophageal disease under his leadership.

    Non-time-orthogonal analysis of rotating frames is applied to objects in gravitational orbits and found to be internally consistent. The object's surface speed about its axis of rotation, but not its orbital speed, is shown to be readily detectable by any "enclosed box" experimenter on the surface of such an object. Sagnac type effects manifest readily, but by somewhat subtle means. The analysis is extended to objects bound in non-gravitational orbit, where it is found to be fully in accord with the traditional analysis of Thomas precession.

    A one-parameter family of Emden-Fowler equations defined by Lampariello's parameter p which, upon using Thomas-Fermi boundary conditions, turns into a set of generalized Thomas-Fermi equations comprising the standard Thomas-Fermi equation for p = 1 is studied in this paper. The entire family is shown to be non integrable by reduction to the corresponding Abel equations whose invariants do not satisfy a known integrability condition. We also discuss the equivalent dynamical system of equations for the standard Thomas-Fermi equation and perform its phase-plane analysis. The results of the latter analysis are similar for the whole class.

    Full Text Available This article proposes an approach to the novel Bekenntnisse des Hochstaplers Felix Krull by Thomas Mann from the point of view of the imaginal psychology of James Hillman. From this perspective the novel seems to illustrate the most innovative thesis of that psychology, which is especially relevant for having been written prior to the formulation of Hillman’s theories. The unplanned correspondence between both ways of thinking furnishes a valuable argument that supports the new conception of human psyche introduced by Carl Gustav Jung and developed in this way by James Hillman.El presente artículo propone una lectura de la novela de Thomas Mann desde la óptica de la psicología imaginal de James Hillman.

  20. Revised Thomas-Fermi approximation for singular potentials

    Dufty, James W.; Trickey, S. B.

    2016-08-01

    Approximations for the many-fermion free-energy density functional that include the Thomas-Fermi (TF) form for the noninteracting part lead to singular densities for singular external potentials (e.g., attractive Coulomb). This limitation of the TF approximation is addressed here by a formal map of the exact Euler equation for the density onto an equivalent TF form characterized by a modified Kohn-Sham potential. It is shown to be a "regularized" version of the Kohn-Sham potential, tempered by convolution with a finite-temperature response function. The resulting density is nonsingular, with the equilibrium properties obtained from the total free-energy functional evaluated at this density. This new representation is formally exact. Approximate expressions for the regularized potential are given to leading order in a nonlocality parameter, and the limiting behavior at high and low temperatures is described. The noninteracting part of the free energy in this approximation is the usual Thomas-Fermi functional. These results generalize and extend to finite temperatures the ground-state regularization by R. G. Parr and S. Ghosh [Proc. Natl. Acad. Sci. U.S.A. 83, 3577 (1986), 10.1073/pnas.83.11.3577] and by L. R. Pratt, G. G. Hoffman, and R. A. Harris [J. Chem.

    2016-03-01

    Full Text Available All philosophers, beginning with the pre-Socratics, through Plato and Aristotle, and up to Thomas Aquinas, accepted as a certain that the world as a whole existed eternally. The foundation for the eternity of the world was the indestructible and eternal primal building material of the world, a material that existed in the form of primordial material elements (the Ionians, in the form of ideas (Plato, or in the form of matter, eternal motion, and the first heavens (Aristotle. The article outlines the main structure of the philosophical theory of creation ex nihilo developed by St. Thomas Aquinas and indebted to his metaphysical thought. It shows the wisdom-based and ratiocinative foundation of the rational cognition of reality—reality that comes from the personal creative act of God. It concludes that the perception that the beings called to existence by the personal act of God the Creator are intelligible is the ultimate rational justification for the fact that our human cognition, love, and spiritual creativity are rational.

  2. Paradigms in epidemiology textbooks: in the footsteps of Thomas Kuhn.

    Science.gov (United States)

    Bhopal, R

    1999-08-01

    This article attempts to contribute to the debate on the future of epidemiology by combining Thomas Kuhn's ideas on scientific paradigms with the author's observations on some epidemiology textbooks. The author's interpretations were based on his readings of Kuhn's The Structure of Scientific Revolutions, epidemiology textbooks, and papers on the future of epidemiology. Thomas Kuhn's view is that sciences mostly work with a single paradigm driven by exemplars of successful work, and that proposals for paradigm change are resisted. Sciences that are maturing or changing do not have a dominant paradigm. Epidemiology textbooks showed diversity in their concepts, content, and approach. Most exemplars related to etiologic research rather than public health practice. One key focus of the recent controversy regarding the role of epidemiology has been the increasing inability of epidemiology to solve socially based public health problems. Kuhn's views help explain the polarization of views expressed. Kuhn's philosophy of science offers insights into controversies such as whether a paradigm shift is needed or imminent and the gap between epidemiology and public health practice. Interaction between science philosophers, epidemiologists, and public health practitioners may be valuable.

    STS-114 Mission Specialists, Andy Thomas and Steve Robinson, are seen in this pre-flight interview. Andy Thomas begins by talking about his interest in spaceflight as a young boy growing up in Australia. He expresses that the chances of an Australian boy studying to eventually become an astronaut was very remote. His Mechanical Engineering Degree in Australia and a Doctorate enabled him to acquire unique skills to come to the United States to work for Lockheed Martin. On the topic of return to flight, he reflects on experiences that he had working with the Michael Anderson and Kalpana Chawla of the ill-fated Space Shuttle Columbia. He also talks about the safety of the Space Shuttle Discovery and repairs to its Thermal Protection system. He explains in detail the Logistics Flight (LF) 1, spacewalks, Multipurpose Logistics Module (MPLM) and the External Stowage Platform (ESP)-2. Steve Robinson expresses that he had many interests as a child and becoming an astronaut was one of them. He was fascinated with things that fly and wanted to find out how they flew. He also designed hang gliders as a teenager. He expresses how his family feels about the risky business of spaceflight. He talks about how the space shuttle discovery crew will remember the Columbia crew by including seven stars on their patch so that they can bring them into orbit and then back home. Robinson also talks about his primary job, and the spacewalks that he and Soichi Noguchi will be performing.

    We construct noncommutative Donaldson-Thomas invariants associated with abelian orbifold singularities by analyzing the instanton contributions to a six-dimensional topological gauge theory. The noncommutative deformation of this gauge theory localizes on noncommutative instantons which can be classified in terms of three-dimensional Young diagrams with a colouring of boxes according to the orbifold group. We construct a moduli space for these gauge field configurations which allows us to compute its virtual numbers via the counting of representations of a quiver with relations. The quiver encodes the instanton dynamics of the noncommutative gauge theory, and is associated to the geometry of the singularity via the generalized McKay correspondence. The index of BPS states which compute the noncommutative Donaldson-Thomas invariants is realized via topological quantum mechanics based on the quiver data. We illustrate these constructions with several explicit examples, involving also higher rank Coulomb branch invariants and geometries with compact divisors, and connect our approach with other ones in the literature.

    Full Text Available Generalmente cuando se aborda el mercantilismo se hace referencia a la acumulación de oro y plata, una balanza de pagos favorable o a la política económica de Jean Colbert. Pero poco se ha hablado del papel y condiciones necesarias del comerciante como agente que hizo posible que los primeros Estados-Nación se convirtieran en las futuras potencias económicas del mundo occidental. Thomas Mun fue uno de aquellos escritores mercantilistas que destacó el papel del comerciante en el auge del sistema mercantilista. El estudio de sus ideas permite concluir que sus recomendaciones acerca de lo que debería ser un comerciante de éxito siguen vigentes hoy en día. La razón de tal afirmación estriba en que sus recomendaciones eran adecuadas en un marco en que se estaba presentando una transformación significativa del sistema de organización comercial con la presencia de la Joint-Stock Company. Independientemente de que muchas de las funciones que Thomas Mun le atribuía al comerciante hoy en día son especializadas, su dominio sigue siendo la clave del éxito de una política comercial que emprenda cualquier nación.

    Full Text Available Starting with a critical analysis of Skinner's ethical system, this paper points to some consequences out of this system for the practice of behavior analysis. Skinner's writings and its conceptual categories are the main source of the arguments presented. Initially, the paper draws an outline of the relation between Skinner's ethical system and selection by consequences as a causal model, proceeding, then, to the analysis of both the descriptive and prescriptive aspects of that system. The paper finishes discussing the implications of these precedent considerations for the professional exercise of behavior analysis. This last part of the paper gives special attention to the role of the behavior analyst as a political agent, and to the need to develop collaborative practices in order to deal with possible tensions between the radical behaviorist ethical system and the values of the people with which the analyst works.

    Corticosterone was injected bilaterally into the dorsal hippocampus of BALB/c Mice immediately after the first extinction session of an operant conditioning in a Skinner box. Compared with the control animals the Mice that received 1 or 0.1 microgram corticosterone exhibited 24 hrs. later, faster extinction of this conditioning. With a 0.01 microgram dose of corticosterone in each hippocampus we obtained an accelerated extinction during the session. These data suggest that corticosterone modulates hippocampal mechanisms involved in memory processes.

    The experimental study of nectar foraging behavior in free-flying bees requires the use of automated devices to control solution delivery and measure dependent variables associated with nectar gathering. We describe a new computer-controlled artificial flower and provide calibration data to measure the precision of the apparatus. Our device is similar to a "Skinner box" and we present data of an experiment where various amounts of a 50% sugar solution are presented randomly to individual bees. These data show large individual variations among subjects across several dependent variables. Finally, we discuss possible applications of our device to problems in behavioral sciences.

  5. The Thomas-Fermi Quark Model: Non-Relativistic Aspects

    CERN Document Server

    Liu, Quan

    2012-01-01

    Non-relativistic aspects of the Thomas-Fermi statistical quark model are developed. A review is given and our modified approach to spin in the model is explained. Our results are limited so far to two inequivalent simultaneous wave functions which can apply to multiple degenerate flavors. An explicit spin interaction is introduced, which requires the introduction of a generalized spin "flavor". Although the model is designed to be most reliable for many-quark states, we find surprisingly that it may be used to fit the low energy spectrum of octet and decouplet baryons. The low energy fit allows us to investigate the six-quark doubly strange H-dibaryon state, possible 6 quark nucleon-nucleon resonances and flavor symmetric strange states of higher quark content.

  6. Motivic Donaldson--Thomas invariants of some quantized threefolds

    CERN Document Server

    Cazzaniga, Alberto; Pym, Brent; Szendroi, Balazs

    2015-01-01

    This paper is motivated by the question of how motivic Donaldson--Thomas invariants behave in families. We compute the invariants for some simple families of noncommutative Calabi--Yau threefolds, defined by quivers with homogeneous potentials. These families give deformation quantizations of affine three-space, the resolved conifold, and the resolution of the transversal $A_n$-singularity. It turns out that their invariants are generically constant, but jump at special values of the deformation parameter, such as roots of unity. The corresponding generating series are written in closed form, as plethystic exponentials of simple rational functions. While our results are limited by the standard dimensional reduction techniques that we employ, they nevertheless allow us to conjecture formulae for more interesting cases, such as the elliptic Sklyanin algebras.

  7. [Is there still a soul? Thomas Aquinas and modern psychiatry].

    Science.gov (United States)

    Koehler, K

    1984-10-01

    The various solutions that have been proposed with respect to the body-mind problem can be more or less regarded as variations on three traditional models. Since the time of Descartes the philosophical position of hylomorphism has been almost forgotten and the influence of the dualist point of view has also been greatly reduced. In contrast, reductionism in the form of materialistic monism has gained immense popularity, especially in psychiatric circles. The present paper summarizes these different approaches but primarily focuses on certain aspects of a modified form of hylomorphism as developed by Thomas Aquinas. These latter considerations are then drawn upon as the basis for a critique of Kurt Schneiders so-called aristotelean-scholastic or metagenic interpretation with regard to the endogenous psychoses.

  8. A Tony Thomas-Inspired Guide to INSPIRE

    Energy Technology Data Exchange (ETDEWEB)

    O' Connell, Heath B.; /Fermilab

    2010-04-01

    The SPIRES database was created in the late 1960s to catalogue the high energy physics preprints received by the SLAC Library. In the early 1990s it became the first database on the web and the first website outside of Europe. Although indispensible to the HEP community, its aging software infrastructure is becoming a serious liability. In a joint project involving CERN, DESY, Fermilab and SLAC, a new database, INSPIRE, is being created to replace SPIRES using CERN's modern, open-source Invenio database software. INSPIRE will maintain the content and functionality of SPIRES plus many new features. I describe this evolution from the birth of SPIRES to the current day, noting that the career of Tony Thomas spans this timeline.

    We present a generalization of fermionic fluiddynamics to the case of two trapped fermion species with a contact interaction. Within a mean field approximation, we derive coupled equations of motion for the particle densities, particle currents, and anomalous pair density. For an inhomogeneous system, the equilibrium situation with vanishing currents is described by a generalized Thomas-Fermi relation that includes the superfluid gap, together with a new nonlocal gap equation that replaces the usual BCS one. These equations are numericaly solved resorting to a local density approximation (LDA). Density and gap profiles are analyzed in terms of the scattering length, revealing that the current frame can exhibit microscopic details of quantum origin that are frequently absent in more macroscopic scenarios.

  10. Algorithmic Thomas Decomposition of Algebraic and Differential Systems

    Bächler, Thomas; Lange-Hegermann, Markus; Robertz, Daniel

    2011-01-01

    In this paper, we consider systems of algebraic and non-linear partial differential equations and inequations. We decompose these systems into so-called simple subsystems and thereby partition the set of solutions. For algebraic systems, simplicity means triangularity, square-freeness and non-vanishing initials. Differential simplicity extends algebraic simplicity with involutivity. We build upon the constructive ideas of J. M. Thomas and develop them into a new algorithm for disjoint decomposition. The given paper is a revised version of a previous paper and includes the proofs of correctness and termination of our decomposition algorithm. In addition, we illustrate the algorithm with further instructive examples and describe its Maple implementation together with an experimental comparison to some other triangular decomposition algorithms.

  11. Whistles, bells, and cogs in machines: Thomas Huxley and epiphenomenalism.

    Science.gov (United States)

    Greenwood, John

    2010-01-01

    In this paper I try to shed some historical light upon the doctrine of epiphenomenalism, by focusing on the version of epiphenomenalism championed by Thomas Huxley, which is often treated as a classic statement of the doctrine. I argue that it is doubtful if Huxley held any form of metaphysical epiphenomenalism, and that he held a more limited form of empirical epiphenomenalism with respect to consciousness but not with respect to mentality per se. Contrary to what is conventionally supposed, Huxley's empirical epiphenomenalism with respect to consciousness was not simply based upon the demonstration of the neurophysiological basis of conscious mentality, or derived from the extension of mechanistic and reflexive principles of explanation to encompass all forms of animal and human behavior, but was based upon the demonstration of purposive and coordinated animal and human behavior in the absence of consciousness. Given Huxley's own treatment of mentality, his characterization of animals and humans as "conscious automata" was not well chosen.

    It is shown that Uhlmann's parallel transport of purifications along a path of mixed states represented by 2 x 2 density matrices is just the path-ordered product of Thomas rotations. These rotations are invariant under hyperbolic translations inside the Bloch sphere that can be regarded as the Poincare ball model of hyperbolic geometry. A general expression for the mixed state geometric phase for an arbitrary geodesic triangle in terms of the Bures fidelities is derived. The formula gives back the solid angle result well known from studies of the pure state geometric phase. It is also shown that this mixed state anholonomy can be reinterpreted as the pure state non-Abelian anholonomy of entangled states living in a suitable restriction of the quaternionic Hopf bundle. In this picture Uhlmann's parallel transport is just the Pancharatnam transport of quaternionic spinors.

    2007-02-01

    Thomas Hobbes postulates that men are driven by "a perpetual and restless desire of power after power, that ceaseth only in death." The miserable consequences of this drive for power and the competing "desire of ease and sensual delight" and "fear of death and wounds" lead them to establish and obey. Substituting "profit" for "power" yields a description of the modern corporation, but without the desires or fears of natural persons. Such "unnatural persons" lack the Hobbesian ground of obligation, yet have appropriated the privileges and protections of natural persons. They challenge or undermine the sovereign wherever it limits their profits. Governor Schwarzenegger's re-election in California, however, on a strong anti-CO(2) program, suggests a willingness by threatened natural persons to re-empower Leviathan.

Se muestra que presentan una consideración diferente de los factores extracientíficos, que tienen en la primera un peso explicativo mayor. Se propone que en 1957 Kuhn maneja una historiografía casuística, centrada en la revolución copernicana, y en 1962 una historiografía estructural, centrada en los rasgos invariantes de las revoluciones científicas. Se concluye que las diferencias entre las dos obras son lo suficientemente profundas como para no considerarlas expresión de una misma visión de la ciencia.

  18. Diversity vs. Difference: A Critical Analysis of Hybridity and Cultural Identity Crisis in the Novels of Cheikh Hamidou Kane and Chinua Achebe

    Alassane Abdoulaye DIA

    2014-03-01

    Full Text Available Hybridity has been one of the most recurrent themes of the African fiction during and after the colonial period. It is one of the complex issues of postcolonial Africa as it was difficult for many Négritude writers, such as Léopold Sédar Senghor, Aimé Césaire, and Frantz Fanon, to find a common ground on what colonization bequeathed to Africa. Hence, Senghor (1977 came up with the oxymoron of “colonization as a necessary evil”. However, to evaluate the advantages and disadvantages of colonization to Africans, in terms of impact, one should go further than expected to approve or dismantle Senghor’s position. The issues of cultural hybridity and identity crisis are still topical in African literature. Also, in the context of globalization, it is relevant to study the post-independence situation of African societies as represented by their early prominent and visionary writers such as Chinua Achebe from Nigeria and Cheikh Hamidou Kane from Senegal. Therefore, hybridity becomes a concern, through which writers address the dilemma of the African. They portray the intellectual who is entrapped in two different cultures and becomes alienated. The corpus of this article showcases this phenomenon through the characters of Obi Okonkwo in No Longer at Ease (1960 and Samba Diallo in Ambiguous Adventure (1962. Through a critical analysis and a post-colonial perspective, the article focuses on identity crisis, alongside the contentious debate over cultural diversity versus cultural difference, which is highly reflected in the novels investigated in the paper.

  20. The light bulb, cystoscopy, and Thomas Alva Edison.

    Science.gov (United States)

    Moran, Michael E

    2010-09-01

    Thomas Alva Edison was an icon of American achievement who literally invented the 20th century. Although best known as the inventor of the electric light bulb, the phonograph, and motion pictures, he also left a lasting legacy via peripheral developmental applications, such as endoscopes. A review of published urologic writings about incandescent cystoscopes was cross-referenced to writings about or from Edison. Important events that allowed transference of technology from the Edison laboratory to clinical practice were emphasized. Edison was born in 1847 while Lincoln was serving in Congress; he died in 1931 when Hoover struggled with the Great Depression. Edison's life spanned the formative period of America that Henry Adams called the "coming of age." Edison received a Sprengel vacuum device in late 1879, and as usual, he was able to tweak the machine to better performance. For 5 days in October, 16 to 21, he improved the vacuum from 1/100,000 to 1/1,000,000 atm, and his first incandescent bulb burned softly. On December 21, 1879, he leaked the story to N.Y. Herald journalist Marshall Fox, and the world was notified of the light bulb. Special Christmas light visits started in Menlo Park just 4 days later. Edison patented the screw cap for easy changes, and the first bulbs sold for 40 cents (cost $1.40). 100,000 bulbs sold in 1882, 4 million by 1892, and 45 million in 1903. Immediately, competitors and specialty manufacturers entered the market. Dr. Henry Koch and Charles Preston in Rochester, N.Y., developed a smaller, low amperage bulb that could be fitted to medical devices. No discussion of electricity and modern applications would be complete without some discussion of Thomas Alva Edison and his sentinel contributions. The first church, post office, and ship were illuminated in 1892. The first hotel, theater, and electric sign were in 1893. The rapidity of dispersal and secondary applications of Edison's inventions is typified by the rise of cystoscopes

  1. On the motivic Donaldson-Thomas invariants of quivers with potentials

    2011-01-01

    We study motivic Donaldson-Thomas invariants for a class of quivers with potentials using the strategy of Behrend, Bryan, and Szendroi. This class includes quivers with potentials arising from consistent brane tilings and quivers with zero potential. Our construction is an alternative to the constructions of Kontsevich and Soibelman. We construct an integration map from the equivariant Hall algebra to the quantum torus and show that our motivic Donaldson-Thomas invariants are images of the natural elements in the equivariant Hall algebra. We show that the inegration map is an algebra homomorphism and use this fact to prove the Harder-Narasimhan relation for the motivic Donaldson-Thomas invariants.

  2. Nietzche's echo--a dialogue with Thomas Altizer.

    2010-03-01

    Prophets provoke psychological unrest, especially when exposing accepted beliefs as profound deceptions. The biblical prophets exemplify such confrontation as do certain atheists ardently opposed to the images of God created by those seers. The German philosopher Friedrich Nietzsche dramatically illustrates this type of counterforce to the Judeo-Christian tradition. His prophet Zarathustra is intended to be a model for the modern mind, one free of superstitions inflicted by antiquated religious dogma. Nietzsche's credo "God is dead" served as a declaration for the nineteenth century. In the twentieth century, it became a theological diagnosis. As a "movement," or "tenor," the death of God or radical theology was spearheaded by Thomas Altizer, a well-published young professor center-staged during the turbulent 1960s. His work foreshadows a new strain of atheism currently represented by biologist Richard Dawkins (2006, The God delusion. New York: Houghton Mifflin), philosopher Daniel Dennett (2006, Breaking the spell. New York: Penquin), neuroscientist Sam Harris (2004, The end of faith. New York: W.W. Norton; 2008, Letter to a Christian nation. New York: Vintage), journalist Christopher Hitchens (2007, God is not great. New York: Twelve), and mathematician John Allen Paulos (Paulos 2008, Irreligion. New York: Hill & Wang). This twenty-first century crusade against belief in God is best understood as a psychodynamic ignited by Altizer's Christian atheism. The present dialogue reflects that dynamic while the prologue and epilogue reveal evidence of Providence amidst claims of God's demise in contemporary history.

    2009-09-20

    Beddoes lectured on chemistry at Oxford in the years that included the French Revolution, the Terror, and the outbreak of war with France, as well as the success in France of the chemical revolution. The very public dispute between Edmund Burke and Joseph Priestley meant that the latter's study of different kinds of air was politically tainted. Beddoes's democratic beliefs and his support for the new chemistry of Lavoisier meant that as chemist and physician he had to deal with complaints that he was potentially seditious and pro-French. His medical theories, allied to pneumatic chemistry and building on the work of Priestley, were accordingly suspect. In spite of that, he became the physician and friend to several members of the Lunar Society of Birmingham and to members of their family, and they in return became his patrons. His collaboration with James Watt was crucial for his development of pneumatic medicine. The full extent of Lunar patronage, and especially that of James Keir and Thomas Wedgwood, has hitherto not been recognized, but it was the concealed scale of that patronage that made possible the execution of Beddoes's ambitious programme of treatment and research.

  4. Sir Thomas Browne Against Error: An Apology for Complexity

    Directory of Open Access Journals (Sweden)

    Giuliana Iannaccaro

    2017-04-01

    Full Text Available In 1646 Sir Thomas Browne published his Pseudodoxia Epidemica, a broad, somewhat encyclopedic catalogue of errors divided into seven books. Browne intended his work as “Enquiries into Vulgar and Common Errors” to help discourage “radicated beliefs” – that is, received opinions based on popular credulity and the unchallenged authority of tradition. Far from being dogmatic and assertive, the treatise engages the modern reader for its defence of open debate and of the value of contradiction; actually, Pseudodoxia appears deeply in tune with the epistemological uncertainty of our times for its complex, relativising and even dubitative approach to all things human. Browne endorses the idea that uncritical acceptance of received notions about the world hinders the advancement of learning; at the same time, though, a rigidly straight path – a unique, simplified method to decipher reality – equally perverts knowledge and is the source of misapprehension and mystification. Building on recent studies on his style and his connection with a culturally and politically convulsed historical period, the present contribution discusses Browne’s notion of complexity and highlights exemplary passages in which he discusses the main source of error: the human tendency to simplify what is complex, thus reducing the interpretation of notions, signs and phenomena to a one-sided and necessarily inadequate undertaking.

The importance of such a kind of knowledge, that is notpossible (nor necessary to reduce into rules and definitions, and that is not acquired with exclusiverecourse to logic is essential for Kuhn within Science. The article investigates the origins of this idea inkuhnian work, searching for influences exerted by Gestalt psychology and the second Wittgenstein. Itexamines the relation between this idea and Kuhn’s most known and important philosophicalcontributions, the concept of paradigm (exemplar and the incommensurability of scientific theories;confirming that without the utilization of a kind of knowledge of this nature such ideas would not havehad the necessary support to be stated. At the end of the article, the importance of tacit knowledgethrough the use of metaphor and thought experiments is revised, as vehicles through which the scientistcan put himself in touch with this dimension of knowledge.

  6. Thomas Willis, the Restoration and the First Works of Neurology.

    Science.gov (United States)

    Caron, Louis

    2015-10-01

    This article provides a new consideration of how Thomas Willis (1621-75) came to write the first works of 'neurology', which was in its time a novel use of cerebral and neural anatomy to defend philosophical claims about the mind. Willis's neurology was shaped by the immediate political and religious contexts of the English Civil War and Restoration. Accordingly, the majority of this paper is devoted to uncovering the political necessities Willis faced during the Restoration of the English monarchy in 1660, with particular focus on the significance of Willis's dedication of his neurology and natural philosophy to the Archbishop of Canterbury, Gilbert Sheldon. Because the Restoration of Charles II brought only a semblance of order and peace, Willis and his allies understood the need for a coherent defense of the authority of the English church and its liturgy. Of particular importance to Sheldon and Willis (and to others in Sheldon's circle) were the specific ceremonies described in the Book of Common Prayer, a manual that directed the congregation to assume various postures during public worship. This article demonstrates that Willis's neurology should be read as an intervention in these debates, that his neurology would have been read at the time as an attempt to ground orthodox worship in the structure of the brain and nerves. The political necessities that helped to shape Willis's project also help us to better understand Willis's innovative insistence that philosophical statements about the mind should be formulated only after a comprehensive anatomical investigation of the brain and nerves.

  7. Truncated ambition: Thomas King Chambers, MD (1817-1889).

    Thomas King Chambers clearly intended to be a physician of note and at times indeed he was mentioned in the same breath as Sir James Paget (1814-1899), Sir Henry Acland (1815-1900) and Francis Anstie (1833-1874). At the time of his death his career was pronounced 'less than brilliant though far from inglorious'. He had made all the right political moves-networking through the medical societies, marrying well and even accompanying the Prince of Wales on his first foreign tour. He wanted to be more than a society doctor, however: he published his clinical lectures and original research, proposed a new paradigm for medicine that he dubbed 'the renewal of life' and found his ideas taken up enthusiastically in the United States. Alas, his career foundered when he suffered an aneurysm and underwent amputation through the thigh. Nevertheless, he made significant contributions to the profession through his service on the General Medical Council and to medical education, in particular to medical education for women, through his strong support of the London School of Medicine for Women. To examine his life is to revisit what makes a life meaningful and worthwhile, for Chambers' life, unlike his body, is remarkably whole.

  8. Invoking Thomas Kuhn: What Citation Analysis Reveals about Science Education

    Science.gov (United States)

    Loving, Cathleen C.; Cobern, William W.

    This paper analyzes how Thomas Kuhn's writings are used by others, especially science education researchers. Previous research in citation analysis is used to frame questions related to who cites Kuhn, in what manner and why. Research questions first focus on the variety of disciplines invoking Kuhn and to what extent Structure of Scientific Revolutions (SSR) is cited. The Web of Science database provides material from 1982 for this analysis. The science education literature is analyzed using back issues from 1985 of the Journal of Research in Science Teaching and Science Education. An article analysis reveals trends in terms of what Kuhnian ideas are most frequently invoked. Results indicate a wide array of disciplines from beekeeping to law cite Kuhn - especially generic citations to SSR. The science education journal analysis reveals pervasive use of the term paradigm, although use is quite varied. The two areas of research in science education most impacted by Kuhn appear to be conceptual change theory and constructivist epistemologies. Additional uses of Kuhn are discussed. The degree to which Kuhn is invoked in ways supporting the theoretical framework of citation analysis, whether his work is misappropriated, and the impact of Kuhn are discussed.

  9. Staphylococcus aureus bacteraemia: 400 episodes in St Thomas's Hospital.

    1984-01-28

    Four hundred episodes of Staphylococcus aureus bacteraemia occurred in St Thomas's Hospital from 1969 to 1983, accounting for 17.5% of all episodes of bacteraemia. The mortality was 24%, half attributable to underlying disease, and was highest in patients over 50. Almost 60% of the bacteraemias were acquired in hospital, and the source of the organism was generally obvious, with vascular access sites the most common (37%). Bone and joint infections accounted for 11.5% of episodes and endocarditis for 7%. Most staphylococci were resistant to penicillin only; three isolates were resistant to methicillin and five to fusidic acid. Microbiologists seldom influenced directly the choice of initial antibiotic treatment (though this usually conformed to the hospital's antibiotic prescribing policy) but had considerable influence over definitive treatment, usually cloxacillin or flucloxacillin alone or in combination with fusidic acid. S aureus bacteraemia is easy to identify and treat, though underlying disease may influence the outcome. Efforts should be made to prevent the largely iatrogenic disease.

  10. The many encounters of Thomas Kuhn and French epistemology.

    Science.gov (United States)

    Simons, Massimiliano

    2017-02-01

    The work of Thomas Kuhn has been very influential in Anglo-American philosophy of science and it is claimed that it has initiated the historical turn. Although this might be the case for English speaking countries, in France an historical approach has always been the rule. This article aims to investigate the similarities and differences between Kuhn and French philosophy of science or 'French epistemology'. The first part will argue that he is influenced by French epistemologists, but by lesser known authors than often thought. The second part focuses on the reactions of French epistemologists on Kuhn's work, which were often very critical. It is argued that behind some superficial similarities there are deep disagreements between Kuhn and French epistemology. This is finally shown by a brief comparison with the reaction of more recent French philosophers of science, who distance themselves from French epistemology and are more positive about Kuhn. Based on these diverse appreciations of Kuhn, a typology of the different positions within the philosophy of science is suggested.

    Full Text Available In this article I intend to highlight a fundamental difference that I have seized between Dionysius interpreted by Thomas of Aquinas and the author of Corpus Areopagiticum. In the first stage, I will present the way in which Thomas understands Dionysius as a simple Aristotelian, then the confession of faith of saint Thomas regarding that particular Dionysius from The Acts of Apostles 17, 34, without, however, noticing the fact that Dionysius invokes the Holy Trinity in his texts, a dogma established only in the first Ecumenical Council of Nicaea (325. However, the most obvious issue that radically separates the two thinkers (Dionysius and Thomas is their way of understanding theology (θεολογία.

    Approximate solutions of the Gross-Pitaevskii (GP) equation, obtained upon neglection of the kinetic energy, are well known as Thomas-Fermi solutions. They are characterized by the compensation of the local potential by the collisional energy. In this article we consider exact solutions of the GP-equation with this property and definite values of the kinetic energy, which suggests the term "kinetic Thomas-Fermi" (KTF) solutions. We point out that a large class of light-shift potentials gives ...

  16. Obituary: Thomas C. Van Flandern (1940-2009)

    Science.gov (United States)

    Dunham, David; Slabinski, Victor

    2011-12-01

    Dr. Thomas Charles Van Flandern, an expert in celestial mechanics and cosmology, died January 9, 2009 in Seattle, Washington, of colon cancer. He was 68. Van Flandern was an astronomer at the U.S. Naval Observatory from 1963 to 1983. He developed software to predict and analyze lunar occultations to improve lunar orbital and fundamental star catalog data. In later years he championed increasingly controversial theories. But his 1978 prediction that some asteroids have natural satellites, which was almost universally rejected, was verified when the Galileo spacecraft photographed Dactyl, a satellite of (243) Ida, during its flyby in 1993. Besides astronomy and computers, he had strong interests in biochemistry and nutrition, and he ran a business selling personal computers in the 1980s. Tom Van Flandern was born June 26, 1940 in Cleveland, Ohio, the first child of Robert F. Van Flandern and Anna Mary Haley. His father, a police officer, left the family when Tom Van Flandern was 5. His mother died when he was 16; he and his siblings then lived with their grandmother, Margery Jobe, until he went to college. Tom Van Flandern became interested in astronomy as a child. He used his first telescope, purchased with newspaper delivery earnings, to observe lunar occultations, and then learned how to predict them, sparking a life-long passion for dynamical astronomy. While attending St. Ignatius High School, Van Flandern and fellow student Thomas Petrie organized the Cleveland Moonwatch team to observe the first artificial satellites, the only team without an adult organizer. In 1958, Tom Van Flandern entered Xavier University where he led the Cincinnati Moonwatch team. He learned computer programming at a summer job with General Electric and wrote software to calculate "look angles" from orbital elements. The Cincinnati team became a top producer of observations using these predictions. Tom obtained a B.S. in mathematics from Xavier in 1962. He spent the next year at

  17. Relativistic equation of state at subnuclear densities in the Thomas-Fermi approximation

    CERN Document Server

    Zhang, Z W

    2014-01-01

    We study the non-uniform nuclear matter using the self-consistent Thomas--Fermi approximation with a relativistic mean-field model. The non-uniform matter is assumed to be composed of a lattice of heavy nuclei surrounded by dripped nucleons. At each temperature $T$, proton fraction $Y_p$, and baryon mass density $\\rho_B$, we determine the thermodynamically favored state by minimizing the free energy with respect to the radius of the Wigner--Seitz cell, while the nucleon distribution in the cell can be determined self-consistently in the Thomas--Fermi approximation. A detailed comparison is made between the present results and previous calculations in the Thomas--Fermi approximation with a parameterized nucleon distribution that has been adopted in the widely used Shen EOS.

  18. Representations of cohomological Hall algebras and Donaldson-Thomas theory with classical structure groups

    CERN Document Server

    Young, Matthew B

    2016-01-01

    We introduce a new class of representations of the cohomological Hall algebras of Kontsevich and Soibelman which we call cohomological Hall modules, or CoHM for short. These representations are constructed from self-dual representations of a quiver with contravariant involution $\\sigma$ and provide a mathematical model for the space of BPS states in orientifold string theory. We use the CoHM to define a generalization of cohomological Donaldson-Thomas theory of quivers which allows the quiver representations to have orthogonal and symplectic structure groups. The associated invariants are called orientifold Donaldson-Thomas invariants. We prove the integrality conjecture for orientifold Donaldson-Thomas invariants of $\\sigma$-symmetric quivers. We also formulate precise conjectures regarding the geometric meaning of these invariants and the freeness of the CoHM of a $\\sigma$-symmetric quiver. We prove the freeness conjecture for disjoint union quivers, loop quivers and the affine Dynkin quiver of type $\\widet...

    CERN Document Server

    2010-01-01

    We define a new type of Hall algebras associated e.g. with quivers with polynomial potentials. The main difference with the conventional definition is that we use cohomology of the stack of representations instead of constructible sheaves or functions. In order to take into account the potential we introduce a generalization of theory of mixed Hodge structures, related to exponential integrals. Generating series of our Cohomological Hall algebra is a generalization of the motivic Donaldson-Thomas invariants introduced in arXiv:0811.2435. Also we prove a new integrality property of motivic Donaldson-Thomas invariants.

  8. The poor in the Epistle of James and the Gospel of Thomas

    Directory of Open Access Journals (Sweden)

    Patrick J. Hartin

    1997-01-01

    Full Text Available This study explores similarities in the thought world of the Epistle of James and the Gospel of Thomas. Particular attention is devoted to the role that the 'poor' and 'poverty' play in both documents. For the Epistle of James it is 'the poor in the world that God has chosen to be rich in faith and heirs of the kingdom' (Ja 2:5.  In a similar vein, in the Gospel of Thomas the kingdom is promised to those who have embraced the poverty of a radical life-style: 'Blessed are the poor, for yours is the kingdom of heaven' (GTh 54. This outlook betrays a basic ethos adopted toward the world. In both the Epistle of James and the Gospel of Thomas the relationship to the world ultimately determines one's relationship to the kingdom or to God. For the Epistle of James the very definition of religion demands that one keep 'oneself unstained from  the world' (Ja 1 :27 and that 'friendship with the world' is enmity with God (Ja 4:4. For the Gospel of Thomas the rejection of the world involves a radical ethos that embraces an intinerant life ('Be passersby' [GTh 42J, which includes a rejection of wealth (GTh 63.'If you do not abstain from the world, you will not find the kingdom' (GTh 27. It is argued that the Gospel of Thomas and the Epistle of James reflect traditional sayings that endorse a similar ethos of radical discipleship.

    The electric field in the crystal planar channels is studied by the Thomas Fermi method. The Thomas-Fermi equation and the corresponding boundary conditions are derived for the crystal planar channels. The numericalsolution for the electric field in the channels between (110) planes of the single crystal silicon and the critical angles ofchannelling protons in them are shown. Reasonable agreements with the experimental data are obtained. The resultsshow that the Thomas-Fermi method for the crystal works well in this study, and a microscopic research of the channelelectric field with the contribution of all atoms and the atomic ionization being taken into account is practical.

  14. Locality of the Thomas-Fermi-von Weizsäcker Equations

    Science.gov (United States)

    Nazar, F. Q.; Ortner, C.

    2017-02-01

    We establish a pointwise stability estimate for the Thomas-Fermi-von Weiz-säcker (TFW) model, which demonstrates that a local perturbation of a nuclear arrangement results also in a local response in the electron density and electrostatic potential. The proof adapts the arguments for existence and uniqueness of solutions to the TFW equations in the thermodynamic limit by Catto et al. (The mathematical theory of thermodynamic limits: Thomas-Fermi type models. Oxford mathematical monographs. The Clarendon Press, Oxford University Press, New York, 1998). To demonstrate the utility of this combined locality and stability result we derive several consequences, including an exponential convergence rate for the thermodynamic limit, partition of total energy into exponentially localised site energies (and consequently, exponential locality of forces), and generalised and strengthened results on the charge neutrality of local defects.

  15. Bouncing Dirac particles: compatibility between MIT boundary conditions and Thomas precession

    CERN Document Server

    Nicolaevici, Nistor

    2016-01-01

    We consider the reflection of a Dirac plane wave on a perfectly reflecting plane described by chiral MIT boundary conditions and determine the rotation of the spin in the reflected component of the wave. We solve the analogous problem for a classical particle using the evolution of the spin defined by the Thomas precession and make a comparison with the quantum result. We find that the rotation axes of the spin in the two problems coincide only for a vanishing chiral angle, in which case the rotation angles coincide in the nonrelativistic limit, and also remain remarkably close in the relativistic regime. The result shows that in the nonrelativistic limit the interaction between the spin and a reflecting surface with nonchiral boundary conditions is completely contained in the Thomas precession effect, in conformity with the fact that these boundary conditions are equivalent to an infinite repulsive scalar potential outside the boundary. By contrast, in the ultrarelativistic limit the rotation angle in the qu...

  16. Metaphysics as the Science of Essence: E. J. Lowe and Thomas Aquinas

    Directory of Open Access Journals (Sweden)

    Alejandro Pérez

    2013-12-01

    Full Text Available Metaphysics after being ignored for years has returned to the center of the stage in contemporary philosophy. Thomas Aquinas has lived a very similar story, which gave birth to analytical Thomism. Despite the work done in this line of research, the metaphysics of Aquinas has been heavily ignored. However, the metaphysics of Thomas Aquinas has an advantage, little discussed among Thomists and “Tomasinos”, and it is the fact that it is essentialist metaphysics. So, in keeping with the work of metaphysical E. J. Lowe, who presents his metaphysics as “serious essentialist” it is shown here that the metaphysics of Aquinas has the same virtues of “serious essentialism”, which allows to postulate it as a valid and plausible position for contemporary metaphysics.

  17. Thomas L. Griffiths: Award for Distinguished Scientific Early Career Contributions to Psychology.

    Science.gov (United States)

    2012-11-01

    Presents a short biography of one of the winners of the American Psychological Association's Award for Distinguished Scientific Early Career Contributions to Psychology (2012). Thomas L. Griffiths won the award for bringing mathematical precision to the deepest questions in human learning, reasoning, and concept formation. In his pioneering work, Thomas L. Griffiths has used probabilistic models and Bayesian learning methods to illuminate an extraordinarily wide range of problems in areas including causal reasoning, high-level hierarchical thinking, cultural evolution, theory formation, and cognitive development while also showing that thinking probabilistically can provide a genuine resolution of the age-old tension between nativism and empiricism. His rigorous mathematical and computational abilities are accompanied by an immensely creative imagination, a sure sense of the important problem, and an unerring touch for the right experiment. Griffith's Award citation and a selected biblography are also presented here.

  18. Thomas Mann's "Tobias Mindernickel" in Light of Sartre's "Being-for-Others"

    Directory of Open Access Journals (Sweden)

    Beth Bjorklund

    1978-01-01

    Full Text Available Sartre's analysis of "Being-for-Others" in Being and Nothingness describes the Self-Other relationship as essentially one of conflict, with the Self attempting either to dominate or to be dominated by the Other. Subject-Object relations are a common theme also in the early works of Thomas Mann, who gives artistic expression to many of the same problems which Sartre later formalized in a philosophical theory. The sado-masochistic character, which is portrayed in several of Thomas Mann's narratives, receives its strongest expression in the story "Tobias Mindernickel," which is here singled out for analysis. Humiliation gives rise to aggression, as the protagonist feels both an attraction and a repulsion for his surrogate lover, a dog. The interpersonal relationships revealed here serve as paradigmatic illustration of Sartre's theory of "Concrete Relations with Others."

  19. Sue Bridehead:The Girl of the Period in Thomas Hardy’s Jude the Obscure

    Institute of Scientific and Technical Information of China (English)

    徐苏

    2014-01-01

    Jude the Obscure was Thomas Hardy’s last novel creation, and he spent eight year from preparation to publication. Al-though this novel received a lot of criticisms instead of praises when it came out, it also can be considered as Thomas Hardy ’s classical works. The theme of this novel is so brave to explore the existing women ’s living circumstances in that time. With the industrial revolution in England, new thoughts and ideas sprang out. Women were no longer belonging to husband and family, and they began to be aware of their social roles and reconsider their identity in society and marriage. The aim of the paper is to analyze this novel from the feministic perspective and re-read the character of Sue Bridehead in the light of the theory“the girl of the period”.

  20. Resonance width distribution in RMT: Weak-coupling regime beyond Porter-Thomas

    Science.gov (United States)

    Fyodorov, Yan V.; Savin, Dmitry V.

    2015-05-01

    We employ the random matrix theory (RMT) framework to revisit the distribution of resonance widths in quantum chaotic systems weakly coupled to the continuum via a finite number M of open channels. In contrast to the standard first-order perturbation theory treatment we do not a priori assume the resonance widths being small compared to the mean level spacing. We show that to the leading order in weak coupling the perturbative χ^2M distribution of the resonance widths (in particular, the Porter-Thomas distribution at M = 1) should be corrected by a factor related to a certain average of the ratio of square roots of the characteristic polynomial (“spectral determinant”) of the underlying RMT Hamiltonian. A simple single-channel expression is obtained that properly approximates the width distribution also at large resonance overlap, where the Porter-Thomas result is no longer applicable.

  1. The infancy Gospel of Thomas: Allegory or myth � Gnostic or Ebionite?

    Directory of Open Access Journals (Sweden)

    A G van Aarde

    2005-10-01

    Full Text Available The aim of this article is to show that scholars assess the Infancy Gospel of Thomas disparagingly as �illogical�, �un-Christian� and �banal�. A more positive judgment is� that it is either �Gnostic� or �purified of Gnosticism�, or merely one of many ancient tales in the form of a historical allegory about Jesus as a child.� The article argues that the author of the Greek version of the Infancy Gospel of Thomas in Codex Sinaiticus (Gr 453 describes the miracles of Jesus in a positive and negative light as if he were an adult.� This phenomenon should be understood against the background that this second-century gospel is presented not so much in the genre of a Gnostic redeemer myth, but rather as a god-child myth that has neither an Orthodox nor a Gnostic orientation. Its context is rather early Ebionite Christianity.

  2. Comment on the equivalence of Bakamjian-Thomas mass operators in different forms of dynamics

    CERN Document Server

    Polyzou, W N

    2010-01-01

    We discuss the scattering equivalence of the generalized Bakamjian-Thomas construction of dynamical representations of the Poincar\\'e group in all of Dirac's forms of dynamics. The equivalence was established by Sokolov in the context of proving that the equivalence holds for models that satisfy cluster separability. The generalized Bakamjian Thomas construction is used in most applications, even though it only satisfies cluster properties for systems of less than four particles. Different forms of dynamics are related by unitary transformations that remove interactions from some infinitesimal generators and introduce them to other generators. These unitary transformation must be interaction dependent, because they can be applied to a non-interacting generator and produce an interacting generator.

    2016-01-01

    A self-consistent description for hot $\\Lambda$ hypernuclei in hypothetical big boxes is developed within the relativistic Thomas-Fermi approximation in order to investigate directly the liquid-gas phase coexistence in strangeness finite nuclear systems. We use the relativistic mean-field model for nuclear interactions. The temperature dependence of $\\Lambda$ hyperon density, $\\Lambda$ hyperon radius, excitation energies, specific heat, and the binding energies of $\\Lambda$ hypernuclei from $^{16}_{\\Lambda}$O to $^{208}_{\\Lambda}$Pb in phase transition region are calculated by using the subtraction procedure in order to separate the hypernucleus from the surrounding baryon gas. The $\\Lambda$ central density is very sensitive to the temperature. The radii of $\\Lambda$ hyperon at high temperature become very large. In the relativistic Thomas-Fermi approximation with the subtraction procedure, the properties of hypernuclei are independent of the size of the box in which the calculation is performed. The level de...

    Marcum, James A

    2015-01-01

    This new edition of Thomas Kuhn's Revolution marks the 50th anniversary of the publication of Kuhn's most influential work. Drawing on the rich archival sources at MIT, and engaging fully with current scholarship, James Marcum provides the historical background to the development of The Structure of Scientific Revolutions. Exploring the shift Kuhn makes from a historical to an evolutionary philosophy of science and examining Kuhn's legacy in depth, Marcum answers key questions: What exactly was Kuhn's historiographic revolution and how did it come about? Why did it have the impact it did? What will its future impact be for both academia and society? Marcum's answers build a new portrait of Kuhn: his personality, his pedagogical style and the intellectual and social context in which he practiced his trade. Thomas Kuhn's Revolution shows how Kuhn transcends the boundaries of the philosophy of science, influencing sociologists, economists, theologians and even policy makers and politicians. This is a comprehensi...

    We study the ionization problem in the Thomas-Fermi-Dirac-von Weizsäcker theory for atoms and molecules. We prove the nonexistence of minimizers for the energy functional when the number of electrons is large and the total nuclear charge is small. This nonexistence result also applies to external potentials decaying faster than the Coulomb potential. In the case of arbitrary nuclear charges, we obtain the nonexistence of stable minimizers and radial minimizers.

  8. Thomas Aquinas on the Soul: Old problems, New Solutions. Guiding Premises for a Thomistic Synthesis

    Directory of Open Access Journals (Sweden)

    Yevgeniy Shilov

    2012-12-01

    Full Text Available This article examines two main approaches to the doctrine of the soul: that of Plato and that of Aristotle. Each of these approaches had its own development and its own interpretations. Plato and his school was more important during the Middle Ages. Through the neo-platonic philosophers it reached Saint Augustine and became a part of the western cultural and religious heritage until finally it was taken up by member of the Franciscan order - Roger Bacon and Bonaventure. But this paradigm could not solve a host of problems connected with the soul and many of them remained unresolved. The end of the twelfth century brought the growth of the universities and the teaching of Aristotle - a new paradigm - transmitted by the Arabic philosophers which was rediscovered by the West. Two commentators on Aristotle - Averroes and Avicenna -were the most important for the West, especially since Avicenna exerted a great influence on Albert the Great. But both Plato and Aristotle, when taken separately, proved to be quite useless in resolving certain problems. But Thomas Aquinas was able to splice the Gordian knot concealing a solution to the problem of the soul. By combining the psychology of Plato with the metaphysics of Aristotle, Thomas succeeded in creating a new concept of the human person. The author of this article has tried to explain the difficulties which faced Thomas and the way in which Thomas was able to resolve a problem which had troubled philosophy through the ages - the problem of reconciling Plato with Aristotle and finding a way to make their conflicting philosophies agree with each other

    Disease is more than dysfunctional organs, morphological abnormalities and genetic divergence. It is also about existence, self-conception and social identity. Disease changes us as persons, but how this happens is usually not discussed in medical textbooks. However, literature appears to be rich in descriptions of these perspectives. This article explores The magic mountain by Thomas Mann to elucidate the relationship between personal identity and disease. I will argue that such knowledge is important to modern clinical practice.

    A study of the performance of Thomas-Fermi and linear response theories in the case of a two-dimensional periodic model system is presented. The calculated density distribution and total energy per unit cell compare very well with exact results except when there is a small number of particles per cell, even though the potential has narrow tight-binding bands. The results supplement earlier findings of Koivisto and Stott for a localized impurity in a two-dimensional uniform gas.

  18. Ethics in the medieval university: the importance of classics reading for the elaboration of Thomas Aquinas

    Tatyana Murer Cavalcante

    2012-05-01

    Full Text Available This paper aims to present some considerations about the importance of reading to the development of the ethics conceptions of Thomas Aquinas (1224 - 5? / 1274. At the dawn of the thirteenth century, the townspeople of Medieval West created a new institution designed for knowledge and education: the University. In it, teachers and disciples were debating key issues for the new society using mainly texts of Ancient Philosophy and Christians, but also Arab and Jewish writings. The literacy forms used encompassed mainly lectio and disputatio , and counteracted by distinct theoretical bases, those thinkers eventually recreated the summa , in a original and fundamental form to the philosophical elaboration of that time. To discuss the importance of reading in the formulation of the concept of ethics in the medieval university, we will present some characteristics of the production of knowledge in the thirteenth century linked to its historical context and then discuss some ethical considerations of Thomas Aquinas, one of the most prominent authors of that period. Considering the limits of this article, only one text, “The object of charity” based on Aquinas major work, the Summa of Theology, will be discussed in depth. Preliminarily, it is possible to state that as well as the reading of classical authors by Thomas Aquinas and other masters of the thirteenth century, helped them develop knowledge about ethics conforming to their time, historical reading of these authors helps in the understanding of today.

    The linear and nonlinear properties of dust-acoustic waves are investigated in a collisionless Thomas-Fermi magnetoplasma, whose constituents are electrons, ions, and negatively charged dust particles. At dust time scale, the electron and ion number densities follow the Thomas-Fermi distribution, whereas the dust component is described by the classical fluid equations. A linear dispersion relation is analyzed to show that the wave frequencies associated with the upper and lower modes are enhanced with the variation of dust concentration. The effect of the latter is seen more strongly on the upper mode as compared to the lower mode. For nonlinear analysis, we obtain magnetized Korteweg-de Vries (KdV) and Zakharov-Kuznetsov (ZK) equations involving the dust-acoustic solitary waves in the framework of reductive perturbation technique. Furthermore, the shock wave excitations are also studied by allowing dissipation effects in the model, leading to the Korteweg-de Vries-Burgers (KdVB) and ZKB equations. The analysis reveals that the dust-acoustic solitary and shock excitations in a Thomas-Fermi plasma are strongly influenced by the plasma parameters, e.g., dust concentration, dust temperature, obliqueness, magnetic field strength, and dust fluid viscosity. The present results should be important for understanding the solitary and shock excitations in the environments of white dwarfs or supernova, where dust particles can exist.

  1. The mask of Thomas Mann (1875-1955): medical insights and last illness.

    Science.gov (United States)

    Carter, R

    1998-02-01

    Thomas Mann, German novelist and essayist, was awarded the Nobel Prize for literature in 1929 for his masterpiece, The Buddenbrooks, aided by his much acclaimed The Magic Mountain, which depicts life in a tuberculosis sanitorium. One of the most medically perceptive writers of the century, Mann was obsessed by illness and disease and produced works that reflect penetrating observation of medicine. When Hitler seized power, Mann fled Germany and entered Switzerland in forced exile. Mann later moved to the United States, becoming an American citizen in 1944. He became embroiled in political turmoil during the red-baiting era; disenchanted with this country, he returned to Switzerland in 1952 and died in Zürich in 1955. This vignette lifts the veil revealing the Mann behind the mask, tormented by life-long homoerotic tendencies that were confirmed by his unexpurgated diaries, published in 1979. I interviewed Professor Christoph Hedinger, who performed the autopsy on Thomas Mann. Professor Hedinger's protocol formed the primary source material for this study and clarified the exact cause of the Nobelist's death. Magisterial, with robust self-regard, Thomas Mann led a life that lends itself as a great human interest story. He was a highly intelligent, complex person whose sexual inversion provides some insight into the person but is irrelevant in assessing his artistic achievements. Mann's defiant stance against the Nazis and his masterful contributions to world literature assure him an enduring and unassailable role in world history.

    To reappraise the early history of odontogenic ghost cell lesions (OGCL), the extensive world literature published from 1838 to 1962 was reviewed. In light of the long history of OGCL, the term "calcifying epithelioma of Malherbe" first appeared in a 1931 French report, and the term "ghost cells" had its origin in two American seminal articles by Thoma and Goldman in 1946. Although Gorlin et al. coined the term "calcifying odontogenic cyst" (COC) in 1962, this type of cyst was initially reported three decades earlier by Rywkind in Russia, and almost concurrently by Blood good in the United States and Sato in Japan. In 1948, Willis provided the initial histological evidence of a peripheral COC in his British pathology textbook. Credit for the earliest clinical presentation of odontoma associated calcifying cystic odontogenic tumor belongs to the American radiology textbook by Thoma in 1917. A Scandinavian journal report published in 1953 by Husted and Pindborg was the first to address a dentinogenic ghost cell tumor, and its peripheral counterpart was originally reported in the Swiss literature 7 years later. The current concept of COC was undoubtedly established by Gorlin et al. but the history of OGCL really started with Thoma's pioneering work about a century ago.

    The modified Thomas test was developed to assess the presence of hip flexion contracture and to measure hip extensibility. Despite its widespread use, to the authors' knowledge, its criterion reference validity has not yet been investigated. The purpose of this study was to assess the criterion reference validity of the modified Thomas test for measuring peak hip extension angle and hip extension deficits, as defined by the hip not being able to extend to 0º, or neutral. Twenty-nine healthy college students (age = 22.00 ± 3.80 years; height = 1.71 ± 0.09 m; body mass = 70.00 ± 15.60 kg) were recruited for this study. Bland-Altman plots revealed poor validity for the modified Thomas test's ability to measure hip extension, which could not be explained by differences in hip flexion ability alone. The modified Thomas test displayed a sensitivity of 31.82% (95% CI [13.86-54.87]) and a specificity of 57.14% (95% CI [18.41-90.10]) for testing hip extension deficits. It appears, however, that by controlling pelvic tilt, much of this variance can be accounted for (r = 0.98). When pelvic tilt is not controlled, the modified Thomas test displays poor criterion reference validity and, as per previous studies, poor reliability. However, when pelvic tilt is controlled, the modified Thomas test appears to be a valid test for evaluating peak hip extension angle.

    以概率自动机(probabilistic automata,PA)为平台,结合遗传算法(genetic algorithm,GA)的进化思想,设计了反映Skinner操作条件反射(operant conditioning,OC)思想的仿生学习模型,称为基于遗传算法的操作条件反射概率自动机(genetic algorithm-operant conditioning probabilistic automata,GA-OCPA)学习系统.每一次学习尝试之后,首先,学习系统把通过OC学习算法学习得到的信息熵值作为个体适应度;然后,执行遗传算法,搜索最优的个体;最后,再执行OC学习算法学习最优个体内的最优操作行为,以得到新的信息熵值.理论上分析了GA-OCPA学习系统学习算法的收敛性,通过对两轮机器人运动平衡控制的仿真分析,表明设计的GA-OCPA学习系统的学习是一个自动获取知识和提炼的过程,具有高度的自适应能力.%Platform on probabilistic automata and combined with evolution thought of genetic algorithm,this paper constructs a bionic learning model which can reflect the essence of Skinner operant conditioning. The designed leaming model is named as genetic algorithm-operant conditioning probabilistic automaton ( GA-OCPA) bionic autonomous learning system After each learning trial, the learning system firstly obtains the information entropy value based on operant conditioning (OC) learning result and uses it as the fitness of individual. And then genetic algorithm is performed based on information entropy value to find the optimal individual. At last,the OC learning algorithm is performed to learn the optimal operant action in optimal individual, and correspondingly a new information entropy value will be obtained. The convergence theorems for the learning algorithm of GA-OCPA bionic learning system is presented, and the simulation analyses in motion balancing control of two-wheeled robot demonstrate that the learning of GA-OCPA bionic learning system is a process of autonomously acquiring and epurating knowledge and has high adaptive

  4. Melt-rock interactions and fabric development of peridotites from North Pond in the Kane area, Mid-Atlantic Ridge: Implications of microstructural and petrological analyses of peridotite samples from IODP Hole U1382A

    North Pond is an isolated sedimentary pond on the western flank of the Kane area along the Mid-Atlantic Ridge. Drill-hole U1382A of IODP Expedition 336 recovered peridotite and gabbro samples from a sedimentary breccia layer in the pond, from which we collected six fresh peridotite samples. The peridotite samples came from the southern slope of the North Pond where an oceanic core complex is currently exposed. The samples were classified as spinel harzburgite, plagioclase-bearing harzburgite, and a vein-bearing peridotite that contains tiny gabbroic veins. No obvious macroscopic shear deformation related to the formation of a detachment fault was observed. The spinel harzburgite with a protogranular texture was classified as refractory peridotite. The degree of partial melting of the spinel harzburgite is estimated to be ˜17%, and melt depletion would have occurred at high temperatures in the uppermost mantle beneath the spreading axis. The progressive melt-rock interactions between the depleted spinel harzburgite and the percolating melts of Normal-Mid Ocean Ridge Basalt (N-MORB) produced the plagioclase-bearing harzburgite and the vein-bearing peridotite at relatively low temperatures. This implies that the subsequent refertilization occurred in an extinct spreading segment of the North Pond after spreading at the axis. Olivine fabrics in the spinel and plagioclase-bearing harzburgites are of types AG, A, and D, suggesting the remnants of a mantle flow regime beneath the spreading axis. The initial olivine fabrics appear to have been preserved despite the later melt-rock interactions. The peridotite samples noted above preserve evidence of mantle flow and melt-rock interactions beneath a spreading ridge that formed at ˜8 Ma.

  5. Thomas McKeown, Meet Fidel Castro: Physicians, Population Health and the Cuban Paradox.

    About 40 years ago, Thomas McKeown demonstrated that the historic decline in the great killer diseases owed little or nothing to progress in medicine. A generation of research on population health followed, highlighting the large social gradients in health within populations. These vary greatly across societies, but appear largely unrelated to medical care. Medicine was acknowledged as "powerful, but within limits"; the major determinants of health lie elsewhere. We may have missed something. Cuba has achieved "first world" population health status despite a minimal economic base. Far from marginalizing medicine, Cuba has by far the world's largest physician workforce. But doctors' roles are significantly expanded. The system seems to work.

  6. Self-dual quiver moduli and orientifold Donaldson-Thomas invariants

    Young, Matthew B

    2014-01-01

    Motivated by the counting of BPS states in string theory with orientifolds, we study moduli spaces of self-dual representations of a quiver with contravariant involution. We develop Hall module techniques to compute the number of points over finite fields in moduli stacks of semistable self-dual representations. Wall-crossing formulas relate these counts for different choices of stability conditions. In particular cases, these formulas model the primitive wall-crossing of orientifold Donaldson-Thomas/BPS invariants suggested in the physics literature. In finite type examples, the wall-crossing can be understood as identities for quantum dilogarithms acting in representations of quantum tori.

    Full Text Available Abstract : To establish an argumentation for the existence of God is properly the most crucial as well as complicated effort in the life of religion and faith of human being. There are various approaches and methods have been applicated to reach it by theologians, thinkers, and scientists, including philosophers with their demonstrative-philosophical method. Some arguments which were initiated by Aristotle are ones of the most popular and have been adopted and improved as well by many thinkers and philosophers after him, some arguments which proposed by Ibn Rusyd and St. Thomas Aquinas with some modifications and improvisations are the best examples of it. In the case of elaboration and analysis toward those arguments for the existence of God, this article attempts to compare between metaphysical thought of Ibn Rushd (well-known in the West as Averroës and St. Thomas Aquinas. There is no doubt that both are Aristotelian in their philosophy. Therefore, to seek the similarities and differences, and to analyze the influence of Aristotle on their modes of thought, especially in argumentation for the existence of God, are an urgent point in the way to find more stronger and relevant arguments.Keywords: argument of creation (dalīl al-ikhtirā`, teleological argument (dalīl al-‘ināyah, unmoved mover, prime cause, influence, parallelism.Abstrak : Menggagas argumentasi tentang eksistensi Tuhan sejatinya merupakan upaya yang paling krusial sekaligus pelik dalam kehidupan beragama dan kepercayaan umat manusia.

  11. Donaldson-Thomas invariants of local elliptic surfaces via the topological vertex

    Bryan, Jim

    2016-01-01

    We compute the Donaldson-Thomas invariants of a local elliptic surface with section. We introduce a new computational technique which is a mixture of motivic and toric methods. This allows us to write the partition function for the invariants in terms of the topological vertex. Utilizing identities for the topological vertex proved in arXiv:1603.05271, we derive product formulas for the partition functions. The connected version of the partition function is written in terms of Jacobi forms. In the special case where the elliptic surface is a K3 surface, we get a new derivation of the Katz-Klemm-Vafa formula.

    Partial genome segments of a begomovirus were previously amplified from Wissadula amplissima exhibiting yellow-mosaic and leaf-curl symptoms in the parish of St. Thomas, Jamaica and this isolate assigned to a tentative begomovirus species, Wissadula golden mosaic St. Thomas virus. To clone the complete genome of this isolate of Wissadula golden mosaic St. Thomas virus, abutting primers were designed to PCR amplify its full-length DNA-A and DNA-B components. Sequence analysis of the complete begomovirus genome obtained, confirmed that it belongs to a distinct begomovirus species and this isolate was named Wissadula golden mosaic St. Thomas virus-[Jamaica:Albion:2005] (WGMSTV-[JM:Alb:05]). The genome of WGMSTV-[JM:Alb:05] is organized similar to that of other bipartite Western Hemisphere begomoviruses. Phylogenetic analyses placed the genome components of WGMSTV-[JM:Alb:05] in the Abutilon mosaic virus clade and showed that the DNA-A component is most closely related to four begomovirus species from Cuba, Tobacco leaf curl Cuba virus, Tobacco leaf rugose virus, Tobacco mottle leaf curl virus, and Tomato yellow distortion leaf virus. The putative Rep-binding-site motif in the common region of WGMSTV-[JM:Alb:05] was observed to be identical to that of Chino del tomate virus-Tomato [Mexico:Sinaloa:1983], Sida yellow mosaic Yucatan virus-[Mexico:Yucatan:2005], and Tomato leaf curl Sinaloa virus-[Nicaragua:Santa Lucia], suggesting that WGMSTV-[JM:Alb:05] is capable of forming viable pseudo-recombinants with these begomoviruses, but not with other members of the Abutilon mosaic virus clade. Biolistic inoculation of test plant species with partial dimers of the WGMSTV-[JM:Alb:05] DNA-A and DNA-B components showed that the virus was infectious to Nicotiana benthamiana and W. amplissima and the cultivated species Phaseolus vulgaris (kidney bean) and Lycopersicon esculentum (tomato). Infected W. amplissima plants developed symptoms similar to symptoms observed under field

    1996-01-01

    The heavy mass limit of quark models based on the Bakamjian-Thomas cons\\-truction reveals remarkable features. In addition to previously demonstrated properties of covariance and Isgur-Wise scaling, exact duality, leading to the Bjorken-Isgur-Wise sum rule, is proven, for the first time to our knowledge in relativistic quark models. Inelastic as well as elastic contributions to the sum rule are then discussed in terms of ground state averages of a few number of operators corresponding to the nonrelativistic dipole operator and various relativistic corrections.

    Full Text Available The papers of the nineteenth century antiquary and surgeon Thomas Pettigrew are of considerable interest in the histories of science, medicine and archaeology. The letters presented here were received by Pettigrew between 1817 and 1859, and form part of the Pettigrew Papers held at Yale University. They were transcribed during research into Pettigrew’s life and work, focusing in particular on his contributions to archaeology and Egyptology, and are presented in the form of texts. They are likely to be of interest and use to scholars of early nineteenth century intellectual history, and historians of archaeology in particular.
