The Ontological Turn Misunderstood: How to Misunderstand David Armstrong’s Theory of Possibility  

OpenAIRE

This article argues that there is a great divide between semantics and metaphysics. Much of what is called metaphysics today is still stuck in the linguistic turn. This is illustrated by showing how Fraser MacBride misunderstands David Armstrong's theory of modality.

Dialectical materialism and the construction of a new quantum theory: David Joseph Bohm, 1917-1992  

International Nuclear Information System (INIS)

This paper touches on some general questions of theory construction in physics, by presenting a biographical case study of David Bohm through the perspective of Fleckian thought-collectives and their thought-style. In the 1920s a small elite of physicists established the Copenhagen Interpretation of quantum mechanics as a new thought-style in the thought-collective of the physicists. In the following decade the Copenhagen Interpretation was transferred from Europe to the USA, from one thought-collective into another, and was integrated into a specific American thought-style. David Bohm was initiated in this mode of thought during his undergraduate studies at the Pennsylvania State College and his graduate studies at Caltech and the University of California at Berkeley.

The reconstitution of political theory: David Easton, behavioralism, and the long road to system.  

Science.gov (United States)

During the last half of the twentieth century, the concept of system was arguably the most important concept in the theoretical repertoire of the discipline of American political science. Although systems analysis was broadly employed in the behavioral sciences, David Easton's work was particularly influential in the study of politics. This is in part because he attempted to develop a distinct account of the political system that was not theoretically subservient either to general systems theory or to conceptions of the social system such as that advanced by Talcott Parsons. Although a great deal of attention has been devoted to Easton's theory, the origins and evolution of the system concept in his work have not been carefully reconstructed and analyzed. PMID:23423865

David Hilbert's lectures on the foundations of physics 1915-1927 relativity, quantum theory and epistemology  

CERN Document Server

A single system of economic governance - capitalism - prevails in the world today, both in theory and in practice. Yet there is neither a standard definition of capitalism nor a theory of how it works. Moreover, the most common conception of capitalism is that of a one-level system governed by markets, i.e., supply and demand, where many socioeconomic externalities are ignored. The purpose of this book is to counter this conception, showing that capitalism is more than markets. In fact, capitalism shares many parallels with everyday organized sports, in that both are indirect, three-level syst

Oral Histories in Meteoritics and Planetary Science—XIX: Klaus Keil  

Science.gov (United States)

Abstract- Klaus Keil (Fig. 1) grew up in Jena and became interested in meteorites as a student of Fritz Heide. His research for his Dr. rer. nat. became known to Hans Suess who--with some difficulty--arranged for him to move to La Jolla, via Mainz, 6 months before the borders of East Germany were closed. In La Jolla, Klaus became familiar with the electron microprobe, which has remained a central tool in his research and, with Kurt Fredriksson, he confirmed the existence of Urey and Craig's chemical H and L chondrite groups, and added a third group, the LL chondrites. Klaus then moved to NASA Ames where he established a microprobe laboratory, published his definitive paper on enstatite chondrites, and led in the development of the Si(Li) detector and the EDS method of analysis. After 5 years at Ames, Klaus became director of the Institute of Meteoritics at the University of New Mexico where he built up one of the leading meteorite research groups while working on a wide variety of projects, including chondrite groups, chondrules, differentiated meteorites, lunar samples, and Hawai'ian basalts. The basalt studies led to a love of Hawai'i and a move to the University of Hawai'i in 1990, where he has continued a wide variety of meteorite projects, notably the role of volcanism on asteroids. Klaus Keil has received honorary doctorates from Friedrich-Schiller University, Jena, and the University of New Mexico, Albuquerque. He was President of the Meteoritical Society in 1969-1970 and was awarded the Leonard Medal in 1988.1 Klaus Keil at the University of Hawai'i at Manoa, 2007.

Connla's well: An exploration of similar elements of ancient Celtic perspectives and David Bohm's theories in quantum physics from a Jungian perspective  

Science.gov (United States)

This dissertation addresses the common elements between ancient Celtic mystical doctrines and philosophy and David Bohm's unique theories in quantum physics through a Jungian lens, using research based in dialogical hermeneutics. The premise of this dissertation is that psi, or the probability wave function of quantum physics, and its world of potentia are the same entities as Jung's objective psyche (or collective unconscious) and its domain, the unus mundus. In addition, the study explores the remarkable similarity between the ancient Celts' Otherworld, quantum physics' world of potentia, and Jung's unus mundus. These similarities argue for an in-depth Jungian analysis of this important but largely neglected mythology. The study explores the supposition, based partially on physicist David Bohm's theories of the implicate and explicate orders, that the above world of potentia intertwines with our three-dimensional world in a reciprocal creativity, designed to enhance both worlds. The study further advocates a greater emphasis on the creative arts therapies in the therapeutic situation, based on the above reciprocity. It is argued that this emphasis on creativity in the temenos may activate a profound "quantum leap" of insight in the analysand, most likely due to the reciprocity in which the objective psyche responds uniquely to the particular and individual creativity offered in order to heal the personal psyche. As we creatively access the objective psyche, that entity responds in kind, giving us new understanding and allowing us to change our attitudes and to further individuation, which in turn enhances the objective psyche. In addition, a psyche of reality is postulated in which Jung's concept of the objective psyche is expanded from the collective unconscious of humankind to a collective unconscious of All That Is, reflecting the findings in quantum physics that our universe is self-aware, organic, and holistic rather than mechanical and fragmented.

David Warner (1934 - 2003)  

CERN Multimedia

It is with great sadness that we learned that our friend and former colleague, David Warner, passed away on Christmas Eve. The funeral was held the following Monday. David was a "linac man". His career centred around linacs, but with a multitude of different subjects. He began at CERN by building the 3 MeV linac in the extension of the South Hall. He did pioneering work on this machine, which paved the way towards the design of the Alvarez cavities for the CERN Linac 2, for which he was responsible. After this challenge was successfully finished, David was the first member of the small but growing team, that was in charge of building the LEP Injector Linacs (LIL). After having been recognised as a proton linac expert, he quickly converted to electron linacs where he soon became the respected key expert for the design, parameters and ultimate performance of LIL. His predilection for precise and detailed documentation, and his vision that the know-how acquired with LIL should be preserved a...

David Bowie's Hauntology  

DEFF Research Database (Denmark)

David Bowie's now-defunct rock-opera trilogy's first installment 1. Outside is filled with uncanny mediations of rock music's chameleon. The inner sleeve booklet is titled The Diary of Nathan Adler, or the Ritual Art-Murder of Baby Grace Blue: A non-linear Gothic Drama Hyper-Cycle. Behind this long-winded title, is the story of a murder, narrated by several characters through both text, music and images. Bowie, however, is the narrator of all these different voices, using technology to distort his voice into these different characters as separate entities. His voice and presence haunts the entire album in uncanny forms, just as all images in the booklet are distorted images of Bowie himself, made into uncanny doubles. The story begins with the murder of Baby Grace Blue, who is enacted by Bowie himself. Symbolically, Bowie is murdered by himself, while Baby Grace haunts the entire album's Gothic and labyrinthine structure. My paper will focus on the mediated double of David Bowie, his ventriloquist voiceand simulacral presence as character, creator and ghost. I will problematize the notion of an outside to the album, focussing on what can be termed the album's hauntological status.

Paranoid, moi? : Erasing David  

DEFF Research Database (Denmark)

The article discusses the relationship between the subject of surveillance and documentary film. As its main example, it uses David Bonds Erasing David from 2009. The genre-specific and film historic aspects of this documentary is analysed and in a further perspective it serves as the point of departure for a more general theoretical discussion of surveillance. Through the treatment of its content and the conceptual framework, Bonds film place itself within what could appropriately be termed the “popular cultural documentary”. What characterises this part of the genre is a critical approach bordering on activism. This is sought combined with the ability to entertain the audience through elements of fiction and comic relief while attempting an analysis of a current and often controversial subject. Michael Moore’s productions are the most successful examples of this filmmaking strategy and two film analytical approaches based on Moore’s 1989 debut Roger & Me is used evaluate the aesthetic and conceptual coherence in Bonds work.     Following this, a three-part taxonomy for the analytical and normative understand of the surveillance phenomenon and its socio-cultural and political implications is established. These are termed: The critical-subversive, the Para cultural and the affirmative mode of understanding. The critical-subversive mode is comparable to the expository documentary form. A strategy, that whether academic or aesthetic, aims at the disclosure of hidden societal mechanisms by way of facts. In a theoretical perspective, this is discussed with Foucault’s idea of the panopticon and more recently Bruno Latour’s corrective counter-concept oligopticon. The Para cultural intervention is explained with Michel de Certeau’s understanding of ‘tactical re-appropriation’. This strategy, like the previous one, is sceptical of a surveillance society and its implications, though it establishes a different, temporary form of critical stanza. The last mode of portrayal is the affirmative. This is directly connectedto the popular cultural representation of surveillance technologies. According to the German art historian O. K. Werkmeister, these are ascribed an almost omnipresent potential. This creates an internalisation of the surveillance culture, one which is paradoxically endorsed by both its supporters and critics.                       Both the theoretical perspective and the film analytical approach to Bonds film determine problematic weaknesses in his project. Bond tends to invest more in cracking the ‘formula’ for a successful presentation of his material, than discovering new formalistic or analytical territory in the filmic exposure of current surveillance culture.

Generalized Stillinger--David Potential  

CERN Document Server

We present an improved version of the Stillinger--David polarization potential of the intermolecular interaction in water. A clear algorithm of construction of a function describing the oxygen-hydrogen interaction in water molecules is formulated. A new approach to the modeling of a function screening the charge-dipole interaction on small distances is developed. To describe the long-range asymptotics of the intermolecular potential, the bare Stillinger--David potential is supplemented by a term related to the interaction of dipole moments of oxygen ions. In addition, we introduce a term involving a deformation of the electron shells of oxygen ions to the polarization component. These corrections allow us to successfully reproduce all essential results of quantum mechanical calculations of the interaction energy for water molecules obtained by Clementi. Analyzing the behavior of the dipole moment of a water molecule as a function of the intermolecular distance, we obtain the estimate of irreducible two-partic...

David Liberman's legacy.  

Science.gov (United States)

This article presents, in the author's own vision, his attempt to consider (and update) the work of an original thinker of contemporary psychoanalysis (in the present). Following a short overview of his biographical data and distinctive traits as maestro and man, it then tries to capture the implications and panoramic vision of Liberman's work, the prevailing questions and problems of psychoanalysis to which it responds. In the author's opinion this involves a serious attempt to systematize clinical psychoanalysis on the basis of singularity and of tolerance to human diversity, with the greatest precision and scientific rigour admitted by the psychoanalytic discipline - avoiding cliché on the one hand and what we might call the mystification of the Oracle on the other. The successive stages of Liberman's production are indicated in terms of the auxiliary disciplines (communication theory, semiotics and linguistics) which he used for his ever more precise systematization of clinical psychoanalysis finally leading to his proposals on 'style' and his vision of the psychopathology of over-adaptation and psychosomatic instances. Other concepts which this paper highlights are: Liberman's conception of analytic dialogue as framed by human interaction; his theorization which stems from this particular empirical base making use of 'operational definitions' and 'intermediary formulations'; his operational definition of transference; and the inclusion of setting inside the 'analytic situation'.

Review essay on David Laibman, Deep History: A Study in Social Evolution and Human Potential  

OpenAIRE

While historical materialism and evolutionism provide similar explanations and ideas regarding the cause of long-term social change, the two theories are rarely used in conjunction with one another. In Deep History,the author David Laibman addresses some of the standard questions of evolutionary social theory and attempts to bridge the two concepts, by showing that historical and materialist explanations are present in both Marxian and evolutionary interpretations of history. His goal: develo...

A series of important papers by David Turnbull and his collaborators in the late 1940's and early 1950's laid the experimental and theoretical foundation of modern nucleation theory. The elegance, versatility, and generality of the phenomenological approach, coupled with brilliant and insightful experimental confirmation, sparked widespread application which continues today. Much of David Turnbull's subsequent work in other subjects grew directly or indirectly from this work

While operating in the artistic field towards absolute irrationality, Lynch does not deny its role in society. It is my belief that the director, as the surrealists, has managed to find a balance between the two ways of being in the world: rational and irrational; by playing with their antitheses. The pleasure of the surrealist game is to go to the depths of the unconscious and return with sufficient material to make a work of art out of it.

The Evolving Dynamics of Organizational Capabilities : An Interview with David J. Teece  

DEFF Research Database (Denmark)

In this paper, Mie Augier provides a rich description of the intellectual traditions, the signifi-cant people and academic institutions that in some way or another made a difference to Davis Teece's own intellectual development. In this sense, it is a dynamic account of the emerging career of a distinguished scholar - but not only that. It is also a description of the co-development of three major disciplinary fields; organization theory, economics and strategic management during three decades or so. David Teece has made several important contribu-tions, perhaps most notably to economics (on the theory of the firm and transaction cost eco-nomics) and strategic management (on dynamic capabilities) while drawing upon organization theory and notions such as organizational routines and bounded rationality. In addition, Augier also provides an interview with David Teece, a true scholar still unsettled with what has been achieved so far - in all three fields: `Maybe I'm wrong; and maybe technology is a special caseand maybe technology and organization do not belong at the core of the theory of the firm. My intuition tells me otherwise.' (David Teece, quoted in this issue).

Physics Nobel prize 2004: Surprising theory wins physics Nobel  

CERN Multimedia

From left to right: David Politzer, David Gross and Frank Wilczek. For their understanding of counter-intuitive aspects of the strong force, which governs quarks inside protons and neutrons, on 5 October three American physicists were awarded the 2004 Nobel Prize in Physics. David J. Gross (Kavli Institute of Theoretical Physics, University of California, Santa Barbara), H. David Politzer (California Institute of Technology), and Frank Wilczek (Massachusetts Institute of Technology) made a key theoretical discovery with a surprising result: the closer quarks are together, the weaker the force - opposite to what is seen with electromagnetism and gravity. Rather, the strong force is analogous to a rubber band stretching, where the force increases as the quarks get farther apart. These physicists discovered this property of quarks, known as asymptotic freedom, in 1976. It later became a key part of the theory of quantum chromodynamics (QCD) and the Standard Model, the current best theory to describe the interac...

Henry David Thoreau: Literary Transcendentalism  

Directory of Open Access Journals (Sweden)

Full Text Available During the mid-19th century, New England was experiencing Transcendentalism as a religious, philosophical and literary movement. Despite being inspired by German and British Romanticism, due to its nature which incorporated true notions of American individualism, Transcendentalism was a distinct American movement. Individuals like Thoreau constructed the political dimension of Transcendentalism by putting their transcendentalist beliefs into action by disobeying the government. The true transcendentalist movement was rooted in various influential factors including but not limited to slavery and the civil war, women’s rights, growing industrialism and social gap.Thoreau’s writings are a fit expression of a life based on high ideals and aspirations which integrates integrity and morality. He tends to spent words in pursuit of spiritual development, and it is due to the universal truth behind the particular and the personal that he conveys transcendent meaning. The present article triesto have a closer look at Thoreau’s transcendental literary theory and the way it was presented in his works of art. The article started with proposing a research question regarding the basis of Thoreau’s Transcendental literary thinking and how he presented it in his writings which he regarded as interconnectionamong physical, intellectual, and spiritual worlds.

Quantum mechanics in the cold war; Quantenmechanik im Kalten Krieg. David Bohm und Richard Feynman  

Energy Technology Data Exchange (ETDEWEB)

In the middle of the 20th century David Bohm and Richard Feynman developed two fundamentally different approaches of modern quantum mechanics: Bohm a realistic interpretation by means of hidden parameters and Feynman the path-integral formalism. This is by this more remarakable, because both physicists started from similar conditions and originated from similar connections. By its comparing approach this study presents more than a contribution to the history of the quantum theory. By the question for the social and cultural conditions of the formation of theories it is furthermore of science-sociological and science-theoretical interest. The in the beginning similar and later different binding of both scientists into the scientific community allows furthermore to study, which adapting pressure each group puts on the individual scientist and the fundamental parts of his research, and which new degrees of freedom in the formation of theories arise, when this constraint is cancelled.

In Deep History,the author David Laibman addresses some of the standard questions of evolutionary social theory and attempts to bridge the two concepts, by showing that historical and materialist explanations are present in both Marxian and evolutionary interpretations of history. His goal: develop a Marxist theory of history from an evolutionist perspective, and surmount the traditional confines of historical materialism, so as to embrace evolutionary conceptions in explaining social change. However, the unbalanced research methodology limits the reach and depth of Laibman’s contribution. The two main shortcomings of his work are discussed in the following sections: The Audience Problem and The Evolutionary Problem.

Boundaries and interfaces in materials: The David A. Smith symposium  

International Nuclear Information System (INIS)

Just over a year ago David Smith died. Then the loss of a distinguished scientist and dedicated teacher was mourned. Now it is time to celebrate his accomplishments both as a scientist and teacher and this book serves as a reminder of his many contributions to the field of boundaries and interfaces. Researchers from ten countries contributed their work to the symposium, many of whom were former students of David from his years in Oxford. This emphasizes David's tremendous effect on the career of many established scientists through his role as both a teacher and an advisor. Separate abstracts were prepared for 38 papers in this book

David and Shimei: Innocent victim and perpetrator?  

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english Feeding on the current social anxiety in the country that is defined by racial lines, the paper suggests the possibility of a theology for the 'retributed', i.e. those who undergo justice in terms of affirmative action or land repossession. Employing Ndebele's thoughts on the folktale The lion and t [...] he rabbit and the issue of justice in Lars von Trier's Dogville as its matrices, the paper enquires into the roles of perpetrator or victim Shimei and David play to each other in Samuel-Kings in order to see whether Shimei's death constitutes retributive justice or whether there is some social benefit in turning him into a purificatory sacrifice in a Girardian sense.

David Lukens Reasoner (1941-1992)  

Science.gov (United States)

David Lukens Reasoner, former head of NASA's Ionospheric Physics branch, died on April 21, 1992. Reasoner was born July 1, 1941. He worked tirelessly to expand NASA's Space Physics Division, bringing his deep experience and personal expertise to bear on the challenges of growth.During the magical period of the late 1950s and early 1960s when America turned its eyes toward space and the Moon, David Lukens Reasoner journeyed north from the nearby Texas town of Dickinson to Rice University with an idea of getting involved in exploring the frontiers of space. He pursued a course of study in electrical engineering and received a bachelor's degree in 1963 and a master's degree in 1964. In the early 1960s, the Space Science Department at Rice was formed, and President John Kennedy visited to say that America chose to go to space not because it is easy but because it is hard and because it would require the very best talents of our nation to succeed. Dave Reasoner was one of those talented people. His excellence in electrical engineering and physics, combined with his natural abilities in the laboratory, suited him ideally for building the machines of space. As a student, he built sounding rocket payloads and multiple instruments for satellites and experiment packages that were placed on the Moon by the Apollo astronauts. He completed his doctoral degree in space science in 1968. It was in these early thrilling days of space exploration that I first met Dave, beginning a friendship and collegial relationship that was to last 27 years.

Conhecimento e natureza na filosofía da David Hume  

Scientific Electronic Library Online (English)

Full Text Available [...] Abstract in spanish La filosofía de Hume fue, durante mucho tiempo, percibida como una filosofía escéptica. Una interpretación naturalista pretende, entre tanto, atribuir nuevos sentidos al aspecto afirmativo de su filosofía, mostrando que Hume estaba interesado en aplicar el método experimental al estudio de la natura [...] leza humana. Su filosofía sería vista como una construcción sobre bases naturalísticas de una teoría del conocimiento y de la naturaleza humana. Eruditos como Kevin Meeker pretenden afirmar que las conclusiones escépticas presentes en la obra de Hume imposibilitan una interpretación naturalista, prevaleciendo, así, una conclusión escéptica radical, de que el conocimiento no es posible. Se pretende mostrar, por medio de un examen de los textos de Hume, que el concepto de conocimiento del que parte Meeker, su concepción de naturalismo e incluso su concepción del papel del escepticismo en la filosofía de Hume están equivocados y que la opción naturalista es lo que da más sentido entre las interpretaciones posibles de su filosofía. Abstract in english The philosophy of David Hume was for a long time conceived as a skeptical philosophy. The naturalistic approach aims, about this point, provides new meanings to the affirmative aspect of his philosophy, by showing that Hume was interested in apply the experimental method in the study of human nature [...] . Then, his philosophy could be seen as a construction - over naturalistic basis - of a theory of knowledge and human nature. Some critics like Kevin Meeker intent to claim that the skeptic conclusions, present in Hume’s works makes impossible such a naturalistic view, prevailing after all the skeptical conclusion of the impossibility of knowledge. This enquiry wants to show, by an analysis of Hume’s texts, that the conceptions of knowledge, naturalism and even this conception of skepticism, applied to Hume’s philosophy is mistaken, and that the naturalistic outcome makes more sense, among the possible interpretations of Hume’s philosophy.

Waltz's Theory of Theory  

DEFF Research Database (Denmark)

Kenneth N. Waltz's 1979 book, Theory of International Politics, is the most influential in the history of the discipline. It worked its effects to a large extent through raising the bar for what counted as theoretical work, in effect reshaping not only realism but rivals like liberalism and reflectivism. Yet, ironically, there has been little attention to Waltz's very explicit and original arguments about the nature of theory. This article explores and explicates Waltz's theory of theory. Central attention is paid to his definition of theory as ‘a picture, mentally formed' and to the radical anti-empiricism and anti-positivism of his position. Followers and critics alike have treated Waltzian neorealism as if it was at bottom a formal proposition about cause-effect relations. The extreme case of Waltz being so victorious in the discipline, and yet being consistently mis-interpreted on the question of theory, shows the power of a dominant philosophy of science in US IR, and thus the challenge facing any ambitious theorising. The article suggests a possible movement of fronts away from the ‘fourth debate' between rationalism and reflectivism towards one of theory against empiricism. To help this new agenda, the article introduces a key literature from philosophy of science about the structure of theory, and particularly about the way even natural science uses theory very differently from what IRs mainstream thinks - and much more like the way Waltz wants his theory used.

Obituary: David L. Band (1957-2009)  

Science.gov (United States)

David L. Band, of Potomac Maryland, died on March 16, 2009 succumbing to a long battle with spinal cord cancer. His death at the age of 52 came as a shock to his many friends and colleagues in the physics and astronomy community. Band showed an early interest and exceptional aptitude for physics, leading to his acceptance at the Massachusetts Institute of Technology as an undergraduate student in 1975. After graduating from MIT with an undergraduate degree in Physics, Band continued as a graduate student in Physics at Harvard University. His emerging interest in Astrophysics led him to the Astronomy Department at the Harvard Smithsonian Center for Astrophysics (CfA), where he did his dissertation work with Jonathan Grindlay. His dissertation (1985) entitled "Non-thermal Radiation Mechanisms and Processes in SS433 and Active Galactic Nuclei" was "pioneering work on the physics of jets arising from black holes and models for their emission, including self-absorption, which previewed much to come, and even David's own later work on Gamma-ray Bursts," according to Grindlay who remained a personal friend and colleague of Band's. Following graduate school, Band held postdoctoral positions at the Lawrence Livermore Laboratory, the University of California at Berkeley and the Center for Astronomy and Space Sciences at the University of California San Diego where he worked on the BATSE experiment that was part of the Compton Gamma Ray Observatory (CGRO), launched in 1991. BATSE had as its main objective the study of cosmic gamma-ray bursts (GRBs) and made significant advances in this area of research. Band became a world-renowned figure in the emerging field of GRB studies. He is best known for his widely-used analytic form of gamma-ray burst spectra known as the "Band Function." After the CGRO mission ended, Band moved to the Los Alamos National Laboratory where he worked mainly on classified research but continued to work on GRB energetics and spectra. When NASA planned two new follow-up missions to CGRO, the Swift and Fermi observatories, Band seized an opportunity in 2001 to join the staff of the Fermi Science Support Center at the NASA Goddard Space Flight Center in Greenbelt Maryland. He was hired as the lead scientist for user support functions and to help to define and implement planning for the 2008 launch of the Fermi spacecraft. He brought a high level of energy and enthusiasm to the job, becoming in many ways the heart and soul of that organization. Neil Gehrels, the Goddard Astroparticle Physics Division Director and a Fermi deputy project scientist notes that "David was the perfect person for community support, with this outgoing personality and deep knowledge of astrophysics." Band also became an important member of the Fermi science team; despite his failing health, he actively contributed to the first Fermi gamma-ray burst publication as well as making important contributions to the burst detection and data analysis techniques. Additionally, Band was known as a great communicator and mentor. He supervised a PhD student at UCSD who has subsequently been appointed to a faculty position. At Goddard, Band was an integral part of the weekly scientific discussion groups within the gamma-ray astronomy group and he would always find the time to share his knowledge and expertise with new postdoctoral fellows and senior scientists alike. He was also involved with planning the EXIST mission, a candidate for a future NASA mission. He will be greatly missed by his many friends and colleagues within the Fermi mission and the high-energy astrophysics community.

Capacity theory on algebraic curves  

CERN Document Server

Capacity is a measure of size for sets, with diverse applications in potential theory, probability and number theory. This book lays foundations for a theory of capacity for adelic sets on algebraic curves. Its main result is an arithmetic one, a generalization of a theorem of Fekete and Szegö which gives a sharp existence/finiteness criterion for algebraic points whose conjugates lie near a specified set on a curve. The book brings out a deep connection between the classical Green's functions of analysis and Néron's local height pairings; it also points to an interpretation of capacity as a kind of intersection index in the framework of Arakelov Theory. It is a research monograph and will primarily be of interest to number theorists and algebraic geometers; because of applications of the theory, it may also be of interest to logicians. The theory presented generalizes one due to David Cantor for the projective line. As with most adelic theories, it has a local and a global part. Let /K be a smooth, complet...

Hacking the aesthetic: David Haines and Joyce Hinterding's new ecologies of signal  

Directory of Open Access Journals (Sweden)

Full Text Available Award winning Australian electronic artists David Haines and Joyce Hinterding's installation work is discussed as “signal-work.” Their work reconfigures signal within original assemblages involving subtle audio, high resolution video (both recorded and animated, kilometers of coiled copper wire, antennae or home-built electronics, electrostatic disturbances, the like of very low frequency radiation from the Milky Way, and cross-signal processing. The article develops a context for thinking about the work in terms of Whitehead's process philosophy, as this is relevant to media theory, as well as concepts of plural ecology and ongoing differentiation drawn from Bateson and Guattari. Signal processing is seen as key to all this. The article argues that in Hinterding and Haines’ signal-work new sensations are produced, outside of the normal “syntax” of some models of aesthetic experience. This challenges some aspects of thinking about both aesthetics and political ecology.

David Mitrany and South-East Europe: The Balkan Key to World Peace  

Directory of Open Access Journals (Sweden)

Full Text Available

Today David Mitrany is best known for his work on international functionalism, which influenced the development of European integration and the organisation of United Nations specialised agencies. What is often ignored in the West is his work on South-East Europe. During the inter-war period Mitrany studied both the operation of war government and the subsequent peasant revolution in the Balkans. War government demonstrated that political organisation could bridge the gap between social action and private property, while the peasant social revolution showed that the abstract economics associated with both capitalist and Marxist economics was not applicable outside of urban industrial production. It was through his studies of South-East Europe that Mitrany drew many of the lessons and concepts that were to form the foundations of his international theory.

The sociology of language in Johann David Michaelis's dissertation of 1760.  

Science.gov (United States)

In 1759 Johann David Michaelis won a prize from the Prussian Royal Academy for his essay Beantwortung der Frage von dem Einfluss der Meinungen in die Sprache, und der sprache in die Meinungen. The essay was published in the following year and translated into French in 1762, into English in 1769, and into Dutch in 1771. The work has two major themes--linguistic relativity and language change--with ancillary discussions of language in general and of homonymy. Its most significant contribution to the theory of language is its discussion of linguistic relativity, especially in its manifestations in the influence of language on thought. Given the intellectual milieu of the work where inquiry was centered on the origin of language and language universals, it stands as one of the few discussions of this topic and it is also one of the most fruitful discussions of linguistic relativity for any period of history.

In order to show that a specific problem is algorithmically solvable, it is sufficient to provide an algorithm that solves it in a sufficiently precise manner.

A new gene mapping resource: Interspecies hybrids between Pere David`s deer (Elaphurus davidianus) and red deer (Cervus elaphus)  

Energy Technology Data Exchange (ETDEWEB)

Three male F{sub 1} hybrids between Pere David`s deer and red deer were mated to red deer to produce 143 backcross calves. The pedigrees are a rare example of a fertile hybrid between evolutionarily divergent species. We examined the use of these families for genetic mapping of evolutionarily conserved (Type I) loci by testing for genetic linkage between five species-specific protein variants and 12 conserved DNA probes. Two probes were homologous, and the remainder syntenic, to the protein coding loci in cattle or humans. Using six restriction enzymes, each DNA probe detected one or more restriction fragments specific to Pere David`s deer. Linkage analyses among the species-specific variants placed the loci into four linkage groups within which linkage between adjacent loci and gene order was supported by a LOD > 3. Southern and protein analysis of LDHA and ALB provided identical segregation data. These linkage groups were consistent with the cattle gene map and provide new information for comparing the gene maps of ruminants, humans and mice. The deer hybrids are an important new resource that can contribute to the comparative analysis of the mammalian genome. 68 refs., 2 figs., 2 tabs.

Part of this stems from the obvious fact that vdW interactions (and other weak forces, such as Casimir) underpin molecular recognition, i.e., nature's approach to search for a match between genes and anti-genes and hence enable biological function. Less obvious is the recognition that vdW interactions affect a multitude of properties of a vast variety of materials in general, some of which also have strong technological applications. While for two atom- or orbital-sized material fragments the dispersive contributions to binding are small compared to those from the better known forms (ionic, covalent, metallic), those between sparse materials (spread over extended areas) can be of paramount importance. For example, an understanding of binding in graphite cannot arise solely from a study of the graphene layers individually, but also requires insight from inter-sheet graphene vdW bonding. It is the extended-area vdW bonding that provides sufficient cohesion to make graphite a robust, naturally occurring material. In fact, it is the vdW-bonded graphite, and not the all-covalently bonded diamond, that is the preferred form of pure carbon under ambient conditions. Also important is the understanding that vdW attraction can attain a dramatic relevance even if the material fragments, the building blocks, are not necessarily parallel from the outset or smooth when viewed in isolation (such as a graphene sheet or a carbon nanotube). This can happen if the building blocks have some softness and flexibility and allow an internal relative alignment to emerge. The vdW forces can then cause increasingly larger parts of the interacting fragments to line up at sub-nanometer separations and thus beget more areas with a sizable vdW bonding contribution. The gecko can scale a wall because it can bring its flexible hairs sufficiently close to any corrugated—and/or any smooth—surface and thus enforce a strong vdW-type adhesion; it exploits what is then essentially a contact force (dominated by the attraction exerted in the near-surface regions) to defy the pull of gravity on its own bulk. This Journal of Physics: Condensed Matter special issue is dedicated to the memory of David C Langreth. David is a dearly missed friend and mentor who inspired many of us. He was an outstanding condensed matter theorist and a scholar who greatly influenced us through his many-particle-physics based insights into density functional theory (DFT), surface science and related areas. His seminal works range from conserving formulations of interacting nonequilibrium transport [1] and formal-scattering theory [2] to an explicit formulation [3] of the exact DFT exchange-correlation energy in the adiabatic connection formula (ACF), the latter also being derived independently by Gunnarsson and Lundqvist [4]. David's portfolio also includes an analysis [5] that helped catalyze and guide the development of DFT from the local-density approximation (LDA) to the formulations of generalized gradient approximations (GGAs). Another salient contribution of David's is in the area of vdW interactions in materials. He was a key architect of the vdW density functional (vdW-DF) method [6, 7]. This method was developed in a long-standing Rutgers-Chalmers collaboration between David's group and that of Bengt I Lundqvist, later extending to a wider group of researchers on both sides of the Atlantic. Plasmons are collective excitations that depend on electron-density variation. The plasmon response can be seen as defining the nature of the LDA [4] and their description can thus also be seen as contributing to the success of GGA. The vdW-DF method is a regular constraint-based density functional (for ground-state DFT) which is derived within the ACF framework and which emphasizes the electrodynamical nature of the coupling between these collective plasmon excitations. The vdW-DF method thus seeks to utilise the implicit

David Hume, Scepticism, Imagination and Political Philosophy  

Directory of Open Access Journals (Sweden)

Full Text Available The main purpose of my presentation is to explore some possible links between Hume’s philosophy of history and imagination. My point is that although Hume has clearly rejected narratives about human history and politics based on modern and rationalist versions of Natural Law, his own accounts on the matter were positively based on arguments that went well beyond some sort of retreat into bare empiricism or scattered historicism. Hume’s stance on the matter of history and politics, to my mind, can be interpreted as an effort to build a natural history of morals, justice and government in which imagination plays a non-negligible role. His criticism of rationalistic natural law theories does not entail the acceptance of empiricist or institutionalist points of view. Of course, empiricist and institutionalist languages are in the use, across Hume’s arrays of arguments, but it seems to me that these languages appear as submitted to the supremacy of imagination. In that sense, we may face in Hume’s theory of justice an alternative view, in the form of a breach between pure rationalistic and empiricist views.

Obituary: David Fulmer Bender, 1913-2004  

Science.gov (United States)

David Fulmer Bender died in San Diego, California, on 13 September 2004, at the age of 91. His heart stopped suddenly while he was dancing. His pioneering work in establishing comprehensive, computer-accessible ephemerides of asteroids and comets found many applications, including the first-ever visit to an asteroid, Gaspra, by an interplanetary spacecraft. Dave was born in Reno, Nevada, on 10 February 1913, to Homer Charles Bender and Susan Bowers Bender. The family moved to Spokane, Washington, while Dave was very young. His father was a civil engineer and a graduate of MIT, who helped design bridges and dams throughout the Northwest, including the Grand Coolie Dam. Dave had a brother, Phillip (now deceased), who was one year younger. Advancing rapidly in the Spokane school system, Dave finished high school when he was 15 years old. At 16 he moved to Pasadena, California, and began his studies at the California Institute of Technology (Caltech). In addition to pursuing his course work, he was active in track and football, a tendency toward physical exercise that stayed with him for the rest of his life. It was probably during these years that Dave heard a lecture by Albert Einstein, as mentioned to colleagues many years later. Dave received a BS degree in physics in 1933, an MS in 1934, and a PhD in 1937, all from Caltech. His dissertation was entitled, "The Index of Refraction of Air in the Photographic Infrared." During his sophomore year he found his way to Pomona College in Claremont, California, where he met his future wife, Elizabeth Boyden at a social gathering. They were married in 1935. Dave's academic career spanned the years from 1937 to 1970, initially at Louisiana State University, Vanderbilt University, and then Fisk. As a life-long pacifist and conscientious objector, Dave served alternate duty during World War II. In 1946 he joined the faculty of the physics department at Whittier College in California, where he became the department chair and remained until 1970. Here Dave's strong personal interest in the students became evident. During each year's spring break, he and Beth led a car caravan of interested astronomy and physics students to Death Valley for primitive camping, exploring the desert, studying the stars, and shooting off rockets. Beth organized all the food and Dave cooked the breakfasts, with French toast being his specialty. This tradition was so popular that many students returned year after year, long after having left the college. Dave enjoyed leading the astronomy club at Whittier College, and also participated in a municipal astronomy club. In the sixties, in addition to his job at the college, Dave worked part time at the Space Science Laboratory of North American Aviation (later North American Rockwell and now Boeing). Dave co-authored, with Gary Mc Cue and others, several papers on orbital rendezvous techniques, a capability of prime interest to the Apollo program. Soon apparent, however, was Dave's interest in the hundreds of asteroids whose orbits were known at the time. In his spare time he punched their orbital elements into computer cards and initiated a long career of searching for opportunities for spacecraft to flyby or rendezvous with one of these minor planets. He learned enough Russian to read books important at the time on the subject of asteroid orbits. In 1966 he had enough data to publish a paper on some possible asteroid encounters by human missions to Mars. Through conferences of the American Astronautical Society, Dave became acquainted with Roger Bourke, the group supervisor of the Advanced Projects Group at the Jet Propulsion Laboratory (JPL), which is managed by Caltech for NASA. In 1970, Dave retired from Whittier College and began working full time for Roger at JPL. JPL was still working on missions to the inner planets and was starting to develop missions to the outer planets. Roger understood the potential of having Dave pursue his interest in the small bodies and of having him create a comprehensive set of ephemerides that would be available for

Pupazzi di neve. David Lynch fotografo e l’"Unheimliche"  

Directory of Open Access Journals (Sweden)

Full Text Available L’opera di David Lynch non si limita al cinema, come ha dimostrato l’esposizione del 2007 alla Fondation Cartier di Parigi, The Air is on Fire. Tuttavia gli studi teorici hanno trascurato ciò che gallerie e musei hanno evidenziato da tempo: il Lynch pittore, fotografo, musicista, artista poliedrico. L’articolo si focalizza su una serie fotografica, Snowmen, ed è tratto da una ricerca di Paolo Sebastiano Lanzi sulla figura di David Lynch fotografo. Alla luce del saggio di Freud sul Perturbante (Das Unheimliche, 1919 si interpretano gli Snowmen come immagini di morte. Si chiariscono alcuni aspetti della poetica dell’artista-regista, come l’inquietudine dell’Inland Empire o di certe idee care al Surrealismo. Lo studio della produzione fotografica di Lynch riempie un vuoto nell’analisi critica sul suo lavoro, che va necessariamente riconsiderato in una prospettiva più ampia.

DAVID: A new video motion sensor for outdoor perimeter applications  

International Nuclear Information System (INIS)

To be effective, a perimeter intrusion detection system must comprise both sensor and rapid assessment components. The use of closed circuit television (CCTV) to provide the rapid assessment capability, makes possible the use of video motion detection (VMD) processing as a system sensor component. Despite it's conceptual appeal, video motion detection has not been widely used in outdoor perimeter systems because of an inability to discriminate between genuine intrusions and numerous environmental effects such as cloud shadows, wind motion, reflections, precipitation, etc. The result has been an unacceptably high false alarm rate and operator work-load. DAVID (Digital Automatic Video Intrusion Detector) utilizes new digital signal processing techniques to achieve a dramatic improvement in discrimination performance thereby making video motion detection practical for outdoor applications. This paper begins with a discussion of the key considerations in implementing an outdoor video intrusion detection system, followed by a description of the DAVID design in light of these considerations

Halberstam passed away this past Monday as the result of injuries he sustained during a car crash in the city of Menlo Park, California. True to his dedication to reporting, Halberstam was on his way to interview Y.A. Tittle, who played football for the New York Giants in the 1950s. Halberstam cut his teeth as the managing editor of The Harvard Crimson as an undergraduate, and then he moved on to write about the early years of the civil-rights movement for both the West Point Daily Times Leader and later for The Nashville Tennessean. He later went on to report on the war in Vietnam, and in 1964 he shared in a Pulitzer Prize with his colleagues at the New York Times. He went on to write over twenty books which explored the 1950s, the world of Michael Jordan (and by extension, the world of professional basketball), and perhaps his most well known work, "The Best and the Brightest". Perhaps Orville Schell, the dean of Berkeley's graduate school of journalism, said it best when he was asked how he felt about Halberstam's sudden death, and remarked that: "What can one say? The fragility of life sometimes just intrudes with a kind of savageness." The first link will take visitors to an excellent obituary of Halberstam written by the Baltimore Sun's own Larry Williams. The second link leads to a piece from Newsweek written by Evan Thomas who remembers his own encounters with Halberstam's work and sphere of influence.

No correlation between neonatal fitness and heterozygosity in a reintroduced population of Père David's deer  

Directory of Open Access Journals (Sweden)

Full Text Available Considering the severe impacts of genetic bottlenecks and small numbers of founders in populations of reintroduced animals, it is necessary to study inbreeding and its effect on fitness in species of conservation concern. Père David’s deer is one of few large mammal species extinct in the wild but safely preserved in captivity. Its specific background gives us the opportunity to study the relationships between heterozygosity and neonatal fitness in relocated populations. We employed five microsatellite loci to explore heterozygosity-fitness correlations in a population of Père David’s deer at the Beijing Milu Ecological Research Center. We observed associations between microsatellite-based variables sMLH, IR, MD2 and HL, and two components of fitness expressed early in life (birth weight and the neonatal mortality of 123 Père David’s deer calves born over six consecutive years. We found that neonatal mortality was 19.1 ± 7.6%, not higher than the 19% or 18% reported in other ungulates. The heterozygosity of calves was not associated with neonatal mortality, nor birth weight. Our study implies that low genetic variability of microsatellite loci has no overt effect on birth weight and neonatal mortality in reintroduced populations of Père David’s deer [Current Zoology 59 (2: 249–256, 2013].

David Elijah Packer (1862-1936), a librarian by profession, was an enthusiastic amateur astronomer who observed from London and Birmingham. He first came to the attention of the astronomical community in 1890 when he discovered a variable star in the globular cluster M5, only the second periodic variable to be discovered in a globular cluster. He also observed meteors and nebulae, on one occasion reporting a brightening in the nucleus of the galaxy M77. However, his remarkable claims in 1896 that he had photographed the solar corona in daylight were soon shown to be flawed.

MOND theory  

CERN Document Server

A general account of MOND theory is given. I start with the basic tenets of MOND, which posit departure from standard dynamics in the limit of low acceleration -- below an acceleration constant a0 -- where dynamics become scale invariant. I list some of the salient predictions of these tenets. The special role of a0 and its significance are then discussed. In particular, I stress its coincidence with cosmologically relevant accelerations. The deep-MOND limit and the consequences of its scale invariance are considered in some detail. General aspects of MOND theories are then described, after which I list briefly presently known theories, both nonrelativistic and relativistic. Most full-fledged theories modify the gravitational action, hinge on a0, introduce an interpolating function between the low and high accelerations, and obey MOND requirements in the opposite limits. These theories have much heuristic value as proofs of various concepts (e.g., that covariant MOND theories can be written with correct gravi...

Shortly after AGU launched its annual voluntary contribution campaign last year—the theme was “Building Tomorrow's Talent Today”—the Union's development office received an e-mail message from David E. Lumley about establishing a scholarship for a high-school student or undergraduate. Many scientific societies and associations have quite a few named scholarships, but for AGU this was a new concept. Lumley was sure of what he wanted to do and even more excited when he learned that his scholarship would be a first for AGU. “I want to help inspire today's young minds to work on problems of global importance in both the energy and environment sectors of industry and academia,” Lumley said. Recipients of the David E. Lumley Young Scientist Scholarship for Energy and Environmental Science will be expected to present a paper and to participate in various student activities at Fall Meeting. “Meeting some of the ‘giants’ of geoscience and getting their feedback on research is a big deal for these young students.

Potential Theory  

CERN Document Server

Within the tradition of meetings devoted to potential theory, a conference on potential theory took place in Prague on 19-24, July 1987. The Conference was organized by the Faculty of Mathematics and Physics, Charles University, with the collaboration of the Institute of Mathematics, Czechoslovak Academy of Sciences, the Department of Mathematics, Czech University of Technology, the Union of Czechoslovak Mathematicians and Physicists, the Czechoslovak Scientific and Technical Society, and supported by IMU. During the Conference, 69 scientific communications from different branches of potential theory were presented; the majority of them are in­ cluded in the present volume. (Papers based on survey lectures delivered at the Conference, its program as well as a collection of problems from potential theory will appear in a special volume of the Lecture Notes Series published by Springer-Verlag). Topics of these communications truly reflect the vast scope of contemporary potential theory. Some contributions deal...

David of the Psalters: MT Psalter, LXX Psalter and 11QPsª Psalter  

Scientific Electronic Library Online (English)

Full Text Available The focus of this paper is on the Davidic figure as presented in the Psalters-the MT Psalter, LXX Psalter and 11QPsª Psalter. David of the MT Psalter is the same figure we encounter in the LXX Psalter and 11QPsª Psalter; however, it is David as he is remembered uniquely in each of the Editorial Vari [...] ant Texts. The MT Psalter is compared with the LXX Psalter and 11QPsª Psalter. Contra Wilson, who argues that the MT Psalter deemphasises David when compared to the other textual witnesses, I argue that the MT Psalter is also susceptible to be read as a highly Davidic book. David is an important character in the Psalter and is the last of Israel's legendary figures mentioned within the bodies of the psalms. In the final analysis, the MT Psalter concludes with David, the sweet psalmist of Israel, remembered for directing Israel in the worship of Yahweh through unconditional praise, a praise resounding from every corner of the cosmos, Yahweh's temple.

Spectroscopies -- Theory  

Science.gov (United States)

This chapter explains how various spectroscopies can be used for probing the many-body quantum state of ultracold gas systems. It starts with a brief reminder of the basic theory of field-matter interactions. The general theory of linear response in the context of many-body quantum physics is then presented. A detailed theoretical description of RF spectroscopy, both the usual one and the momentum-resolved version, is given. This description applies to Raman spectroscopy as well. The basic theory behind Bragg spectroscopy and lattice modulation spectroscopy is also discussed. I explain how RF spectroscopy relates to the spectral function and how Bragg spectroscopy relates to the dynamical/static structure factor. The derivations are detailed and Green's functions are not used, so it is possible to follow this chapter based on simply knowing the basics of second quantization. Finally, self-consistent linear response theory and the use of sum rules is discussed in an overall manner.

The influence of David Keeling on oceanic CO2 measurements  

Science.gov (United States)

Dave Keeling—only Roger Revelle called him "Charles David" and always in a tone that could command Dave's attention—had a remarkable influence on the creation of modern understanding of the oceanic CO2 system. Although Dave resided at an oceanographic institution for almost his entire professional career, the great majority of his work concerned atmospheric measurements; his own account of his work [Keeling, 1998] makes scant reference to his ocean science papers. But those relatively few oceanic papers, and more importantly his intense personal interest and unimpeachable reputation for classic measurement, had enormous impact. It is possible to trace Dave's influence on oceanic measurement through the course of five decades, and over that time, our understanding has grown enormously. The following is a somewhat personal account, but Dave so influenced the careers of the small group of ocean CO2 scientists that have led the way that any one of them would write a similar account.

David Botstein Part 1: Fruits of the Genome Sequences  

Science.gov (United States)

This lecture from the iBioSeminars project is presented by David Botstein from Princeton University. It presents an overview of the benefits for science and society derived from sequencing the genomes of multiple organisms, including humans. The sequences show that many genes have been conserved during evolution; a finding that allows scientists to study simple organisms such as yeast and relate their findings to mammalian biology. In addition, mining genome sequences has identified numerous genes involved in human disease, in some cases resulting in improved screening and treatment. This video is the first of two, running 52:11 minutes and can be downloaded in QuickTime, MP4, M4V, or PDF formats. It can also be streamed on iTunes or YouTube.

David Rumsey Map Collection: 1979 California Water Atlas  

Science.gov (United States)

In a state where water has been a serious public policy issue for many decades, creating an atlas of water resources and usage was considered an important undertaking. That's just what happened in 1979 when the state of California released this groundbreaking atlas. After its release that year, it was hailed as a major achievement in cartography and scientific endeavor from a variety of groups and organizations, including the Quarterly Review of Biology and the California Historical Quarterly. Recently David Rumsey and Cartography Associates scanned the entire original volume in all of its detailed glory, and it is now available for general use here. The atlas can be viewed in a number of different formats, including pdf files or an online book, courtesy of the Internet Archive. Plates from the atlas include "Crop Patterns and Applied Water", "Annual Runoff and Seasonality", and "Measured and Unimpaired Streamflows". It's a masterful work, and one that visitors will want to let friends know about.

Infinite potential the life and times of David Bohm  

CERN Document Server

Throughout his life, David Bohm felt himself to be different, and this was reflected in his lifestyle and in his physics. His life was one of unfulfilled searching. If one compares mainstream physics to the church, with a solid hierarchy of cardinals, archbishops and bishops, Bohm was an ascetic hermit who would occasionally come in from the wilderness with a compelling message, only to disappear again. Bohmian quantum mechanics is not part of mainstream physics, but for those who do cross over, like John Bell, the commitment can be rewarding. In the post-war 'Un-American Activities' purge, Bohm lost a prestigious job at Princeton and t emporarily his US citizenship, and his nomadic career took him to Brazil, Israel and Bristol before he finally settled in London's Birkbeck College. A sensitive-written book about a gifted, unusual and sometimes provocative figure. The interaction between Bohm and Oppenheimer is especially interesting, while Bohm's later life was bizarre.

Concept theory  

DEFF Research Database (Denmark)

  Concept theory is an extremely broad, interdisciplinary and complex field of research related to many deep fields with very long historical traditions without much consensus. However, information science and knowledge organization cannot avoid relating to theories of concepts. Knowledge organizing systems (e.g. classification systems, thesauri and ontologies) should be understood as systems basically organizing concepts and their semantic relations. The same is the case with information retrieval systems. Different theories of concepts have different implications for how to construe, evaluate and use such systems. Based on "a post-Kuhnian view" of paradigms this paper put forward arguments that the best understanding and classification of theories of concepts is to view and classify them in accordance with epistemological theories (empiricism, rationalism, historicism and pragmatism). It is also argued that the historicist and pragmatist understandings of concepts are the most fruitful views and that this understanding may be part of a broader paradigm shift that is also beginning to take place in information science.  The importance of historicist and pragmatic theories of concepts for information science is outlined.

Determinants of vigilance in a reintroduced population of Père David's deer  

Directory of Open Access Journals (Sweden)

Full Text Available After being kept in captivity and isolated from natural predators for more than 1,200 years, Père David’s deer has been reintroduced in China and now occurs in a reserve where human activity is the only potential threat. Antipredator vigilance is an important component of survival for many prey animals in their natural habitat. Do deer still adjust vigilance as a function of risk after such a long period of relaxed predation pressure? Here, we examined vigilance levels in Père David’s deer groups as a function of group size, sex and level of human disturbance. The results showed that individual vigilance significantly decreased with group size in all-female groups but not in all-males or mixed-sex groups. In rutting season, males compete with one another and harass females, and we argue that vigilance is partly aimed at threatening males and that such vigilance increases with group size. This explains why overall vigilance did not vary with group size for males in general and for females in mixed-sex groups. Vigilance increased in more disturbed areas but in in male deer only. The results indicate that despite relaxed predation pressure over centuries, Père David’s deer can still adjust antipredator responses as a function of perceived risk. Such information may become useful in the rewilding programme now under way for this species in China [Current Zoology 59 (2: 265–270, 2013].

Toxinotyping of Clostridium perfringens fecal isolates of reintroduced Père David's deer (Elaphurus davidianus) in China.  

Science.gov (United States)

Clostridium perfringens is an important pathogen causing sudden death syndrome, necrotic enteritis, and gas gangrene in ruminants, especially some deer species. Père David's deer (Elaphurus davidianus) is one of the world's rare species and is an endangered and protected species in China. Some Père David's deer in the Chinese Shishou Père David's Deer Preserve died due to C. perfringens infection. We investigated the toxin types and C. perfringens enterotoxin-positive (cpe(+)) strains of isolated C. perfringens in Père David's deer in China. We collected 155 fecal samples from the Beijing Nanhaizi Père David's Deer Park and the Jiangsu Dafeng Père David's Deer National Nature Reserve between July 2010 and July 2011. Bacteria isolated using blood agar and mannitol agar plates were identified by Gram staining and nested PCR for 16S rRNA. We isolated C. perfringens from 41 fecal samples and used PCR amplification of five toxin genes to identify the toxinotypes and the cpe(+) strains of C. perfringens. Twenty-one isolates were type A, 15 were type E, and five were type D. Fifteen isolates were cpe(+) strains, including eight that were type A and seven that were type E. PMID:25050802

Marr borrowed much of the “computational” level from James Gibson: a proper understanding of the goal of vision, the natural constraints, and the available information is prerequisite to describing the processes and mechanisms by which the goal is achieved. Yet as a research program leading to a computational model of human vision, Marr’s program did not succeed. This article asks why, ...

Geometrical properties of conformal field theories coupled to two-dimensional quantum gravity  

CERN Document Server

In this work we discuss an approach due to F. David to the geometry of world sheets of non-critical strings in quasiclassical approximation. The gravitational dressed conformal dimension is related to the scaling behavior of the two-point function with respect to a distance variable. We show how this approach reproduces the standard gravitational dressing in the next order of perturbation theory. With the same technique we calculate the intrinsic Hausdorff dimension of a world sheet.

Scattering theory  

Energy Technology Data Exchange (ETDEWEB)

Written by the author of the widely acclaimed textbook. Theoretical Atomic Physics Includes sections on quantum reflection, tunable Feshbach resonances and Efimov states. Useful for advanced students and researchers. This book presents a concise and modern coverage of scattering theory. It is motivated by the fact that experimental advances have shifted and broadened the scope of applications where concepts from scattering theory are used, e.g. to the field of ultracold atoms and molecules, which has been experiencing enormous growth in recent years, largely triggered by the successful realization of Bose-Einstein condensates of dilute atomic gases in 1995. In the present treatment, special attention is given to the role played by the long-range behaviour of the projectile-target interaction, and a theory is developed, which is well suited to describe near-threshold bound and continuum states in realistic binary systems such as diatomic molecules or molecular ions. The level of abstraction is kept as low as at all possible, and deeper questions related to mathematical foundations of scattering theory are passed by. The book should be understandable for anyone with a basic knowledge of nonrelativistic quantum mechanics. It is intended for advanced students and researchers, and it is hoped that it will be useful for theorists and experimentalists alike.

Theory summary  

International Nuclear Information System (INIS)

This is a summary of the advances in magnetic fusion energy theory research presented at the 17th International Atomic Energy Agency Fusion Energy Conference from 19 24 October, 1998 in Yokohama, Japan. Theory and simulation results from this conference provided encouraging evidence of significant progress in understanding the physics of thermonuclear plasmas. Indeed, the grand challenge for this field is to acquire the basic understanding that can readily enable the innovations which would make fusion energy practical. In this sense, research in fusion energy is increasingly able to be categorized as fitting well the 'Pasteur's Quadrant' paradigm, where the research strongly couples basic science ('Bohr's Quadrant') to technological impact ('Edison's Quadrant'). As supported by some of the work presented at this conference, this trend will be further enhanced by advanced simulations. Eventually, realistic three-dimensional modeling capabilities, when properly combined with rapid and complete data interpretation of results from both experiments and simulations, can contribute to a greatly enhanced cycle of understanding and innovation. Plasma science theory and simulation have provided reliable foundations for this improved modeling capability, and the exciting advances in high-performance computational resources have further accelerated progress. There were 68 papers presented at this conference in the area of magnetic fusion energy theory

String Theory  

Science.gov (United States)

While few people toss around terms like Astroparticle Physics and Superstring Theory, we've all found ourselves staring out in to space on a starry night wondering what's out there, why it's arranged the way it is, and where it all came from. For some, it simply comes down to strings. This September 2, 2003 New York Times article does a good job of summarizing the history and specifics of string theory and the paradox of its many offerings (1). One-time egistration is required to access any New York Times articles. The next site is the homepage of the Kavli Institute for Theoretical Physics at the University of California Santa Barbara and home to some of the most intense thinking with regards to theoretical physics in the world (2). Going from highly technical to more popularly palatable, NOVA offers the third site (3 ). Called, The Elegant Universe, the upcoming NOVA special is based on Columbia University professor Brian Greene's highly acclaimed book of the same title. As the site states, "Eleven dimensions, parallel universes, and a world made out of strings. It's not science fiction, it's string theory." The next site takes you directly to the virtual home of string theory (4 ). Here you will find the basics on the topic as well as what scientists have found so far and where they're headed next. Probably the most definitive site devoted to the topic. The fifth site is another informative look at superstring theory and is provided by John Pierre at MIT. While a very basic Web site, in terms of design, it offers a great tutorial on strings in addition to a glossary and reference list (5 ). The final link (6 ) will take you "Beyond Einstein, from the Big Bang to Black Holes." The site, provided by NASA, offers insights into the history and structure of the universe.

Transatlantic Miscommunication in David Hare’s Drama Stuff Happens  

Directory of Open Access Journals (Sweden)

Full Text Available This article addresses the transatlantic relations between the United States and Europe and specifically Great Britain in the context of post-9/11 international politics as reflected in the drama Stuff Happens (2004 written by British playwright David Hare. It focuses on the way re­cent history is performed and contextualized in dramatic form and analyzes the function and power of the theatricalization of historic events and particularly of finding ways to address 9/11 on a stage. Furthermore, it discusses the method of mixing parts of public speeches quoted ver­batim with fiction and its effects on readers and audiences. The play addresses the struggles and fragility of international diplomacy in the aftermath of 9/11. It reflects a general skepticism to­wards politicians and their decisions as well as the helpless position of millions of observers who are affected by these decisions and yet feel like they have no influence. This article sees post-9/11 verbatim theater as a chance for playwright and spectators to get access to the world of politics and to take part in the process of writing transatlantic history. More generally, through the ex­ample of this play, the article aims at discussing new challenges and functions of post-9/11 theater.

DAVID HUME AND THE CRITICAL EXAMINATION OF EMPIRICISM  

Directory of Open Access Journals (Sweden)

Full Text Available The research is related to David Hume. This philosopher is described as being an empiricist, but it should be noted that the empiricism promoted by Hume represents the development up to the final consequences of this philosophical doctrine that should be subjected to the observability requirement. The core problem for Hume’s philosophy is the difficulty of causality thinking. The Scottish philosopher promotes a moderate and inconsistent skepticism because he does not doubt the permanency of facts. The Humean epistemology is mixed with elements belonging to some naïve ontology of a materialistic nature and with elements of a sensualistic psychology of an associationist type. The causality or the causal connection between events is based on a psychological belief, which has a pragmatic end for people, in that it offers us the psychological comfort of habitual events and the familiar existential. Causality refers to certain events that have already happened in a certain way, but it cannot constitute a necessary and sufficient basis for similar future events.

Decay of Ethics in David Mamet’s American Buffalo  

Directory of Open Access Journals (Sweden)

Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on human spirits and relations and how it is contradicted in different ways through the analysis of his brilliant play, American Buffalo by David Mamet. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, as one of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life. On the other hand, this individualism, as an ideology, is sustained by other capitalist ideologies such as advertising, consumerism and emulation. It will also be discussed that monetary interests are all one seeks in a highly competitive atmosphere and nothing is privileged over business ethics. In brief, this reading of the play tries to illuminate that we live in a dream-like world of ideologies that block logical thinking and forge our relationship with our real existence through less suspected ways.Keywords: American Dream, Ideology, Capitalism, Individualism, Consumerism

“Silencio”: hearing loss in David Lynch's Mulholland Drive  

Directory of Open Access Journals (Sweden)

Full Text Available In a filmmaking career replete with extraordinary images and sounds, David Lynch's Mulholland Drive (2001 stands out for attention as a striking and seemingly inexhaustible resource for analysis. In this article, this film is used to examine the specific ways in which Lynch uses pre-existing pop songs to wrap the spectator within the filmic soundscape. Nowhere is the complexity and uncanniness of pop music made more explicit than in Rebekah Del Rio's stunning performance of “Llorando (Crying” in the Club Silencio scene. The split between the singer's powerful performance and her subsequent collapse with the sound of the voice left hanging in the air marks a pivotal point in the film. This scene, coupled with other examples of feminine jouissance, is contrasted with the deadening roar of the master's voice, which solely demands obedience but is deaf to any reply. At the core of this article is an analysis of the status of the voice (and the gaze as examples of the Lacanian object a and its relationship to Marx's concept of surplus value. Mulholland Drive provides a powerful demonstration of how these concepts can be seen, heard, and felt in relation to film, and how sound can reverberate into the spaces and silences beyond the screen.

Communication theory  

DEFF Research Database (Denmark)

Communication theory covers a wide variety of theories related to the communication process (Littlejohn, 1999). Communication is not simply an exchange of information, in which we have a sender and a receiver. This very technical concept of communication is clearly outdated; a human being is not a data processing device. In this chapter, communication is understood as a process of shared meaning-making (Bruner, 1990). Human beings interpret their environment, other people, and themselves on the basis of their dynamic interaction with the surrounding world. Meaning is essential because people ascribe specific meanings to their experiences, their actions in life or work, and their interactions. Meaning is reshaped, adapted, and transformed in every communication encounter. Furthermore, meaning is cocreated in dialogues or in communities of practice, such as in teams at a workplace or in school classes (Stelter, 2007).

Potential theory  

CERN Document Server

Potential Theory presents a clear path from calculus to classical potential theory and beyond, with the aim of moving the reader into the area of mathematical research as quickly as possible. The subject matter is developed from first principles using only calculus. Commencing with the inverse square law for gravitational and electromagnetic forces and the divergence theorem, the author develops methods for constructing solutions of Laplace's equation on a region with prescribed values on the boundary of the region. The latter half of the book addresses more advanced material aimed at those with the background of a senior undergraduate or beginning graduate course in real analysis. Starting with solutions of the Dirichlet problem subject to mixed boundary conditions on the simplest of regions, methods of morphing such solutions onto solutions of Poisson's equation on more general regions are developed using diffeomorphisms and the Perron-Wiener-Brelot method, culminating in application to Brownian motion.

This paper discusses some simple issues that arise in testing models, with a focus on models for low energy nuclear structure. By way of simplified examples, we illustrate some dangers in blind statistical assessments, pointing out especially the need to include theoretical uncertainties, the danger of over-weighting precise or physically redundant experimental results, the need to assess competing theories with independent and physically sensitive observables, and the value of statistical tests properly evaluated.

Information Theory, Inference and Learning Algorithms  

Science.gov (United States)

Information theory and inference, often taught separately, are here united in one entertaining textbook. These topics lie at the heart of many exciting areas of contemporary science and engineering - communication, signal processing, data mining, machine learning, pattern recognition, computational neuroscience, bioinformatics, and cryptography. This textbook introduces theory in tandem with applications. Information theory is taught alongside practical communication systems, such as arithmetic coding for data compression and sparse-graph codes for error-correction. A toolbox of inference techniques, including message-passing algorithms, Monte Carlo methods, and variational approximations, are developed alongside applications of these tools to clustering, convolutional codes, independent component analysis, and neural networks. The final part of the book describes the state of the art in error-correcting codes, including low-density parity-check codes, turbo codes, and digital fountain codes -- the twenty-first century standards for satellite communications, disk drives, and data broadcast. Richly illustrated, filled with worked examples and over 400 exercises, some with detailed solutions, David MacKay's groundbreaking book is ideal for self-learning and for undergraduate or graduate courses. Interludes on crosswords, evolution, and sex provide entertainment along the way. In sum, this is a textbook on information, communication, and coding for a new generation of students, and an unparalleled entry point into these subjects for professionals in areas as diverse as computational biology, financial engineering, and machine learning.

Options theory  

International Nuclear Information System (INIS)

Techniques used in conventional project appraisal are mathematically very simple in comparison to those used in reservoir modelling, and in the geosciences. Clearly it would be possible to value assets in mathematically more sophisticated ways if it were meaningful and worthwhile so to do. The DCf approach in common use has recognized limitations; the inability to select a meaningful discount rate being particularly significant. Financial Theory has advanced enormously over the last few years, along with computational techniques, and methods are beginning to appear which may change the way we do project evaluations in practice. The starting point for all of this was a paper by Black and Scholes, which asserts that almost all corporate liabilities can be viewed as options of varying degrees of complexity. Although the financial presentation may be unfamiliar to engineers and geoscientists, some of the concepts used will not be. This paper outlines, in plain English, the basis of option pricing theory for assessing the market value of a project. it also attempts to assess the future role of this type of approach in practical Petroleum Exploration and Engineering economics. Reference is made to relevant published Natural Resource literature

Cluster-like coordinates in supersymmetric quantum field theory.  

Science.gov (United States)

Recently it has become apparent that N = 2 supersymmetric quantum field theory has something to do with cluster algebras. I review one aspect of the connection: supersymmetric quantum field theories have associated hyperkähler moduli spaces, and these moduli spaces carry a structure that looks like an extension of the notion of cluster variety. In particular, one encounters the usual variables and mutations of the cluster story, along with more exotic extra variables and generalized mutations. I focus on a class of examples where the underlying cluster varieties are moduli spaces of flat connections on surfaces, as considered by Fock and Goncharov [Fock V, Goncharov A (2006) Publ Math Inst Hautes Études Sci 103:1-211]. The work reviewed here is largely joint with Davide Gaiotto and Greg Moore. PMID:24982190

Directory of Open Access Journals (Sweden)

Full Text Available This study attempts to provide a theoretical framework for the corporate governance debate. The review of various corporate governance theories enhances the major objective of corporate governance which is maximizing the value for shareholders by ensuring good social and environment performances. The theories of corporate governance are rooted in agency theory with the theory of moral hazard’s implications, further developing within stewardship theory and stakeholder theory and evolving at resource dependence theory, transaction cost theory and political theory. Later, to these theories was added ethics theory, information asymmetry theory or the theory of efficient markets. These theories are defined based on the causes and effects of variables such as: the configuration of the board of directors, audit committee, independence of managers, the role of top management and their social relations beyond the legal regulatory framework. Effective corporate governance requires applying a combination

Memory, modelling and Marr: a commentary on Marr (1971) ‘Simple memory: a theory of archicortex’  

Science.gov (United States)

David Marr's theory of the archicortex, a brain structure now more commonly known as the hippocampus and hippocampal formation, is an epochal contribution to theoretical neuroscience. Addressing the problem of how information about 10 000 events could be stored in the archicortex during the day so that they can be retrieved using partial information and then transferred to the neocortex overnight, the paper presages a whole wealth of later empirical and theoretical work, proving impressively prescient. Despite this impending success, Marr later apparently grew dissatisfied with this style of modelling, but he went on to make seminal suggestions that continue to resonate loudly throughout the field of theoretical neuroscience. We describe Marr's theory of the archicortex and his theory of theories, setting them into their original and a contemporary context, and assessing their impact. This commentary was written to celebrate the 350th anniversary of the journal Philosophical Transactions of the Royal Society. PMID:25750246

The post-perspectival: screens and time in David Lynch's Inland Empire  

Directory of Open Access Journals (Sweden)

Full Text Available Taking Anne Friedberg's notion of the post-perspectival as the point of departure for her analysis of David Lynch's digitally shot and edited Inland Empire from 2006, Anne Jerslev argues that the film deconstructs continuous time and coherent space by constructing multiple planes of representation, multiple layerings of screens and, hence, multiple and fractured modes of perception. The article further suggests that the film's enigmatic structure might best be understood with reference to a new media genre like the website with its hyperlink structure. Finally, the article discusses how a sense of ubiquitous surveillance coalesces with the screen logic.Author Biography Anne Jerslev (PhD is Professor of Film and Media Studies at the Department of Media, Cognition and Communication, University of Copenhagen.

Seyed Mohammad Hossein Tabatabai and David Hume in the philosophical basis for determining the values  

Directory of Open Access Journals (Sweden)

Full Text Available allameh sayyid muhammad husain tabatabaei and David Hume, in regard to influential philosophical thought's, are very important, one in the Muslim world and The other in the West world. Allama has mentioned his thoughts on ethics, in his two books, the principles of philosophy and Method of realism and Al-Mizan interpretation (Quranic exegesis. In The principles of philosophy and Method of realism, his main discussions are actions that export from agent and the relationship between agent and action. In the sixth chapter of the book, Allama generally analyzes mental aspects, and in particular, examines the psychophilosophical analysis and epistemology of the moral concepts. In terms of epistemology, ethics is one of the perceptions of mental aspects, and according to Allama, humans naturally can distinct right from wrong and take steps towards goodness and happiness. The second psychophilosophical aspect of ethics is related to good moral qualities and spiritual positive properties. As was stated before, humans, by nature, are equipped with the ability to recognize right and wrong; so it can be concluded in the issue of good moral qualities and spiritual positive properties, that virtues and vices are in the form of spiritual positive properties and that actualized in regard to need of Physical actions, and accordingly, humans are forced to take action. Allama in epistemological discussions and how human can obtain the knowledge has analyzed the agency of human and relationship between the agent and the action with the aim of demonstrating the role of reason and perceptions in all levels of human life as central and substantial.Hume at the beginning of the third book, a treatise on human nature, stated that "Morality is a subject that interests us above all others"; He spoke of the importance of this field of philosophy. You can even ponder and reflect on the previous parts of the book so that the introductions of a scheme of ethics are discussed. Hume's moral philosophy can be considered as "virtue-based ethics". The main concepts of his ethical theory are such as Behavior, virtues and vices, and not a duty, maxims and obligation. The salient feature of Hume's moral theory is the emphasis upon moral sense according which we discern vicious and virtuous behavior. Consequently, according to Taylor, "Hume's ethics can be contrasted with other forms of virtue-based ethics, such as Aristotelian ethics." In Aristotelian virtue ethics, the focus is on the virtuous agent, and to investigate how people can be involved in the acquisition of virtues and deals with the role of virtue in having a good and calm life; whereas Hume is merely deals with diagnoses and assess the treatment. Most of his work is behavior cognition, and partly psychological and is based on an act-centered attitude. His attitude of moral knowledge based on good and bad behaviors of people is distinguished and evaluated on the context of society and the dialogue and discussion. In other words, evaluation and recognition of the moral norms of virtues- or vices-based is a social practice and the social conditions make it clear. Accordingly, Hume argues that "passions as hate, anger, respect, love, courage, pain and pleasure, all of them bring from the communication with others within the community and not from my natural mood." As a result, one can say that the Allameh Tabatabai argues that human, by nature, has the ability to distinguish right from wrong, and therefore, there are virtues and vices in the form of spiritual positive properties and that actualized in regard to need of Physical actions, and accordingly, humans are forced to take action. Then, human with using the power of "wisdom", can distinguish between virtues and vices. However, Hume explicitly does not consider distinguishing between good and evil as the act of reason, but of "moral sense", and According to him, "reason is the slave of the passions

Decidability of formal theories and hyperincursivity theory  

Science.gov (United States)

This paper shows the limits of the Proof Standard Theory (briefly, PST) and gives some ideas of how to build a proof anticipatory theory (briefly, PAT) that has no such limits. Also, this paper considers that Gödel's proof of the undecidability of Principia Mathematica formal theory is not valid for axiomatic theories that use a PAT to build their proofs because the (hyper)incursive functions are self-representable.

Review of Hydroelasticity Theories  

DEFF Research Database (Denmark)

Existing hydroelastic theories are reviewed. The theories are classified into different types: two-dimensional linear theory, two-dimensional nonlinear theory, three-dimensional linear theory and three-dimensional nonlinear theory. Applications to analysis of very large floating structures (VLFS) are reviewed and discussed in details. Special emphasis is placed on papers from China and Japan (in native languages) as these papers are not generally publicly known in the rest of the world.

Beyond Gauge Theories  

OpenAIRE

Superstring theory, and a recent extension called M theory, are leading candidates for a quantum theory that unifies gravity with the other forces. As such, they are certainly not ordinary quantum field theories. However, recent duality conjectures suggest that a more complete definition of these theories can be provided by the large N limits of suitably chosen U(N) gauge theories associated to the asymptotic boundary of spacetime.

From chaos to unification: U theory vs. M theory  

International Nuclear Information System (INIS)

A unified physical theory called U theory, that is different from M theory, is defined and characterized. U theory, which includes spinor and twistor theory, loop quantum gravity, causal dynamical triangulations, E-infinity unification theory, and Clifford-Finslerian unifications, is based on physical tradition and experimental foundations. In contrast, M theory pays more attention to mathematical forms. While M theory is characterized by supersymmetry string theory, U theory is characterized by non-supersymmetry unified field theory.

DAVID Knowledgebase: a gene-centered database integrating heterogeneous gene annotation resources to facilitate high-throughput gene functional analysis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Due to the complex and distributed nature of biological research, our current biological knowledge is spread over many redundant annotation databases maintained by many independent groups. Analysts usually need to visit many of these bioinformatics databases in order to integrate comprehensive annotation information for their genes, which becomes one of the bottlenecks, particularly for the analytic task associated with a large gene list. Thus, a highly centralized and ready-to-use gene-annotation knowledgebase is in demand for high throughput gene functional analysis. Description The DAVID Knowledgebase is built around the DAVID Gene Concept, a single-linkage method to agglomerate tens of millions of gene/protein identifiers from a variety of public genomic resources into DAVID gene clusters. The grouping of such identifiers improves the cross-reference capability, particularly across NCBI and UniProt systems, enabling more than 40 publicly available functional annotation sources to be comprehensively integrated and centralized by the DAVID gene clusters. The simple, pair-wise, text format files which make up the DAVID Knowledgebase are freely downloadable for various data analysis uses. In addition, a well organized web interface allows users to query different types of heterogeneous annotations in a high-throughput manner. Conclusion The DAVID Knowledgebase is designed to facilitate high throughput gene functional analysis. For a given gene list, it not only provides the quick accessibility to a wide range of heterogeneous annotation data in a centralized location, but also enriches the level of biological information for an individual gene. Moreover, the entire DAVID Knowledgebase is freely downloadable or searchable at http://david.abcc.ncifcrf.gov/knowledgebase/.

Rationality, Theory Acceptance and Decision Theory  

Directory of Open Access Journals (Sweden)

Full Text Available Following Kuhn's main thesis according to which theory revision and acceptance is always paradigm relative, I propose to outline some possible consequences of such a view. First, asking the question in what sense Bayesian decision theory could serve as the appropriate (normative theory of rationality examined from the point of view of the epistemology of theory acceptance, I argue that Bayesianism leads to a narrow conception of theory acceptance. Second, regarding the different types of theory revision, i.e. expansion, contraction, replacement and residuals shifts, I extract from Kuhn's view a series of indications showing that theory replacement cannot be rationalized within the framework of Bayesian decision theory, not even within a more sophisticated version of that model. Third, and finally, I will point to the need for a more comprehensive model of rationality than the Bayesian expected utility maximization model, the need for a model which could better deal with the different aspects of theory replacement. I will show that Kuhn's distinction between normal and revolutionary science gives us several hints for a more adequate theory of rationality in science. I will also show that Kuhn is not in a position to fully articulate his main ideas and that he well be confronted with a serious problem concerning collective choice of a paradigm.

Bohmian mechanics. The physics and mathematics of quantum theory  

International Nuclear Information System (INIS)

Bohmian Mechanics was formulated in 1952 by David Bohm as a complete theory of quantum phenomena based on a particle picture. It was promoted some decades later by John S. Bell, who, intrigued by the manifestly nonlocal structure of the theory, was led to his famous Bell's inequalities. Experimental tests of the inequalities verified that nature is indeed nonlocal. Bohmian mechanics has since then prospered as the straightforward completion of quantum mechanics. This book provides a systematic introduction to Bohmian mechanics and to the mathematical abstractions of quantum mechanics, which range from the self-adjointness of the Schroedinger operator to scattering theory. It explains how the quantum formalism emerges when Boltzmann's ideas about statistical mechanics are applied to Bohmian mechanics. The book is self-contained, mathematically rigorous and an ideal starting point for a fundamental approach to quantum mechanics. It will appeal to students and newcomers to the field, as well as to established scientists seeking a clear exposition of the theory. (orig.)

PEOPLE IN PHYSICS: David Bohm and the implicate order: a new paradigm for physics teachers  

Science.gov (United States)

David Bohm (1917-93) was a highly original and individual physicist. His novel ideas and profound intuition extended not only to the physical world but also to the nature of consciousness and society. Bohm regarded science as having become essentially fragmented in its approach to understanding physical reality and sought a more holistic physics based on order, transformation and flowing movement. His notion of an implicate order provides an unusual and exciting challenge for both teachers and students alike.

An Insight into the Diversity of Mr. Dick’s Roles in David Copperfield  

Directory of Open Access Journals (Sweden)

Full Text Available In David Copperfield, Mr. Dick has played a diversity of roles. He serves not only as a comic figure who brings absurdity and laughter to these harsh experiences, a representative of innocence in disguise of a mentally disabled man, but also as a necessary mental counselor and a domestic helper to others. By exploring those roles to their fullest Charles Dickens has created a unique character that is enchanting as well as complicated.

We suggest that starting from a type I superstring theory one can get to an effective chiral four-dimensional theory with softly broken supersymmetry that is ultraviolet finite to all orders. Previously we classified all two-loop-finite chiral anomaly-free N=1 theories. By requiring that such a theory contain at least three families without mirror partners and the necessary Higgs fields, we are led to a unique theory based on SU(5) and containing exactly three families.

Using optically scanned 3D data in the restoration of Michelangelo's David  

Science.gov (United States)

Modern 3D scanning technologies allow to reconstruct 3D digital representations of Cultural Heritage artifacts in a semi-automatic way, characterized by very high accuracy and wealth of details. The availability of an accurate digital representation opens several possibilities of utilization to experts (restorers, archivists, museum curators), or to ordinary people (students, museum visitors). 3D scanned data are commonly used for the production of animations, interactive visualizations, or virtual reality applications. A much more exciting opportunity is to use these data in the restoration of Cultural Heritage artworks. The integration between 3D graphic and restoration represents an open research field where many new supporting tools are required; the David restoration project has given several starting points and guidelines to the definition and development of innovative solutions. Digital 3D models can be used in two different but not subsidiary modes: as an instrument for the execution of specific investigations and as a supporting media for the archival and integration of all the restoration-related information, gathered with the different studies and analysis performed on the artwork. In this paper we present some recent work done in the framework of the Michelangelo's David restoration project. A 3D model of the David was reconstructed by the Digital Michelangelo Project, using laser-based 3D scanning technology. We have developed some tools to make those data accessible and useful in the restoration. Preliminary results are reported here together with some directions for further research.

Gauge theory loop operators and Liouville theory  

International Nuclear Information System (INIS)

We propose a correspondence between loop operators in a family of four dimensional N=2 gauge theories on S4 - including Wilson, 't Hooft and dyonic operators - and Liouville theory loop operators on a Riemann surface. This extends the beautiful relation between the partition function of these N=2 gauge theories and Liouville correlators found by Alday, Gaiotto and Tachikawa. We show that the computation of these Liouville correlators with the insertion of a Liouville loop operator reproduces Pestun's formula capturing the expectation value of a Wilson loop operator in the corresponding gauge theory. We prove that our definition of Liouville loop operators is invariant under modular transformations, which given our correspondence, implies the conjectured action of S-duality on the gauge theory loop operators. Our computations in Liouville theory make an explicit prediction for the exact expectation value of 't Hooft and dyonic loop operators in these N=2 gauge theories. The Liouville loop operators are also found to admit a simple geometric interpretation within quantum Teichmueller theory as the quantum operators representing the length of geodesics. We study the algebra of Liouville loop operators and show that it gives evidence for our proposal as well as providing definite predictions for the operator product expansion of loop operators in gauge theory.

Neo-newtonian theories  

CERN Document Server

General Relativity is the modern theory of gravitation. It has replaced the newtonian theory in the description of the gravitational phenomena. In spite of the remarkable success of the General Relativity Theory, the newtonian gravitational theory is still largely employed, since General Relativity, in most of the cases, just makes very small corrections to the newtonian predictions. Moreover, the newtonian theory is much simpler, technically and conceptually, when compared to the relativistic theory. In this text, we discuss the possibility of extending the traditional newtonian theory in order to incorporate typical relativistic effects, but keeping the simplicity of the newtonian framework. We denominate these extensions neo-newtonian theories. These theories are discussed mainly in the contexts of cosmology and compact astrophysical objects.

Instinto e razão na natureza humana, segundo Hume e Darwin / Instinct and reason in human nature in David Hume and Charles Darwin  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Esta discussão pretende mostrar pontos relevantes de uma comparação entre a obra de David Hume e de Charles Darwin, no que toca às capacidades cognitivas humanas e de outros animais. Hume tem uma teoria que explica o conhecimento causal em termos de um instinto natural - o hábito. A presença de tal [...] instinto pode ser entendida remetendo-se a uma teoria geral da natureza, onde o mundo é entendido como governado por leis e regularidades constantes, e sem a suposição da interferência de um plano ou desígnio. Isto conduz Hume à aproximação entre a capacidade cognitiva humana e a de outros animais, que também manifestam um aprendizado instintivo do tipo causal. Darwin, por sua vez, menciona uma graduação de diversas capacidades de conhecimento, diferenciando a ação instintiva da ação que resulta de deliberação e inferência; e aponta para o fato de que muitos animais apresentam um grau significativo de comportamento inteligente. Seu mecanismo de evolução por seleção natural pretende explicar essas características, tanto no homem como nos animais. Disso resulta contemporaneamente uma corrente em epistemologia que tem recebido o nome de epistemologia evolutiva, a qual, ao seguir declaradamente Darwin, carece de uma interpretação mais detalhada do pensamento de Hume, que poderia, supõe-se, oferecer elementos para o tratamento de questões epistemológicas tais como a da capacidade para o conhecimento causal. Abstract in english This discussion intends to show some relevant elements, in order to establish a comparison between the works of David Hume and Charles Darwin concerning human and other animal's cognitive capacities. Hume develops a theory to explain causal knowledge in terms of a natural instinct - habit. The prese [...] nce of this instinct can be understood by reference to a general theory of nature that conceives the world governed by constant laws and regularities, without any supposition of interference of an external design or intention. This leads Hume in the way of an approximation between human cognitive capacities and the cognitive capacities of other animals, which also reveals instinctive learning of causal type. Darwin, on his turn, offers a graduation of many capacities of knowledge, distinguishing instinctive action from action resulting from deliberation and inference, and points to the fact that many animals have a significant degree of intelligent behavior. Darwinian mechanism of evolution by natural selection wants to explain this character, in humans as much as in animals. From that results the contemporary fashion in epistemology called evolutionary epistemology that, by following Darwin, lacks a more detailed interpretation of Hume's teaching that could, we suppose, offer elements to the treatment of questions such as the capacity of causal knowledge.

Separation-individuation theory and attachment theory.  

Science.gov (United States)

Separation-individuation and attachment theories are compared and assessed in the context of psychoanalytic developmental theory and their application to clinical work. As introduced by Margaret Mahler and John Bowlby, respectively, both theories were initially regarded as diverging from traditional views. Separation-individuation theory, though it has had to be corrected in important respects, and attachment theory, despite certain limitations, have nonetheless enriched psychoanalytic thought. Without attachment an infant would die, and with severely insecure attachment is at greater risk for serious disorders. Development depends on continued attachment to a responsive and responsible caregiver. Continued attachment to the primary object was regarded by Mahler as as intrinsic to the process of separation-individuation. Attachment theory does not account for the essential development of separateness, and separation-individuation is important for the promotion of autonomy, independence, and identity. Salient historical and theoretical issues are addressed, including the renewed interest in attachment theory and the related decline of interest in separation-individuation theory. PMID:15222460

Higher Topos Theory  

CERN Document Server

Higher category theory is generally regarded as technical and forbidding, but part of it is considerably more tractable: the theory of infinity-categories, higher categories in which all higher morphisms are assumed to be invertible. In Higher Topos Theory, Jacob Lurie presents the foundations of this theory, using the language of weak Kan complexes introduced by Boardman and Vogt, and shows how existing theorems in algebraic topology can be reformulated and generalized in the theory's new language. The result is a powerful theory with applications in many areas of mathematics. The book's firs

Theory by Process  

Science.gov (United States)

Theories defined in a process model are formalized and studied. A theory in a process calculus is a set of perpetually available processes with finite interactability, each can be regarded as a service, an agent behind the scene or an axiom. The operational and observational semantics of the theories are investigated. The power of the approach is demonstrated by interpreting the asynchronous ?-calculus as a theory, the asynchronous theory, in the ?-calculus. A complete axiomatic system is constructed for the asynchronous theory, which gives rise to a proof system for the weak asynchronous bisimilarity of the asynchronous ?.

Obliczeniowe teorie ?wiadomo?ci (Computational theories of consciousness  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper, I review the motivations for having a computational theory of consciousness to see if they turn out to be no longer plausible in the light of recent criticisms. These criticisms focus on the alleged inability of computational theories to deal with qualia, or qualities of experience (or objects of experience in some accounts, and with so-called symbol grounding on the other hand. Yet it seems that computationalism remains the best game in town when one wants to explain and predict the dynamics of information processing of cognitive systems. Conscious information processing does not seem to be explainable better within any other framework; computationalism regarding consciousness can only be discarded by supposing that consciousness is epiphenomenal in information processing.I will argue that recent theories of consciousness that are to deal with the so-called hard problem of consciousness remain in their core computational if they do not subscribe to epiphenomenalism. For example, the quantum theory as proposed by Stuart Hameroff remains openly computational; the same goes for pan(protopsychist speculation of David Chalmers. The qualitative character of information processing that Chalmers takes to explain the existence of subjective experience piggy-backs, so to say, on the very fact that there is information processing that is best explained in a computationalist framework. I also briefly show that other alternative accounts of consciousness (such as direct theories of consciousness that were supposed to oppose computational and functionalist conceptions are not only compatible with them but require them to begin with.In short, to discard credentials of computationalism in consciousness research one would have to show that it`s possible to explain conscious information-processing mechanisms sufficiently in a non-computational way. And this has not been done by any of the critics of computational accounts. This all doesn`t suggest, though, that computational explanation is sufficient for building a complete theory of consciousness; it might however be necessary.

Asymptotic freedom in the theory of the strong interaction. Comment on the nobel prize in physics 2004  

International Nuclear Information System (INIS)

The 2004 Nobel Prize in Physics was awarded to David J. Gross, Frank Wilczek and H. David Politzer for their decisive contributions to the theory of the asymptotic freedom of the strong interaction (a fundamental interaction). The fundamental elements of quantum chromodynamics (QCD) and the theory of the strong interaction are briefly reviewed in their historical context. How to achieve asymptotic freedom is introduced and its physical meaning explained. The latest experimental tests of asymptotic freedom are presented, and it is shown that the theoretical prediction agrees excellently with the experimental measurements. Perturbative QCD which is based on the asymptotic freedom is outlined. It is pointed out that the theoretical discovery and experimental proof of the asymptotic freedom are crucial for QCD to be the correct theory of strong interaction. Certain frontier research areas of QCD, such as 'color confinement', are mentioned. The discovery and confirmation of asymptotic freedom has indeed deeply affected particle physics, and has led to QCD becoming a main content of the standard model, and to further development of the so-called grand unification theories of interactions.

Algebraic conformal field theory  

International Nuclear Information System (INIS)

Many conformal field theory features are special versions of structures which are present in arbitrary 2-dimensional quantum field theories. So it makes sense to describe 2-dimensional conformal field theories in context of algebraic theory of superselection sectors. While most of the results of the algebraic theory are rather abstract, conformal field theories offer the possibility to work out many formulae explicitly. In particular, one can construct the full algebra A-bar of global observables and the endomorphisms of A-bar which represent the superselection sectors. Some explicit results are presented for the level 1 so(N) WZW theories; the algebra A-bar is found to be the enveloping algebra of a Lie algebra L-bar which is an extension of the chiral symmetry algebra of the WZW theory.

Topological field theory  

International Nuclear Information System (INIS)

We begin with a general discussion of topological field theories, their defining properties, and classification. The first model we consider in detail (section 3) is supersymmetric quantum mechanics. Topological sigma models, their observables, and the associated mathematics of complex geometry and intersection theory are presented in section 4. Following this, topological gauge theories are discussed in section 5, with particular emphasis on Donaldson theory. The matematics here is necessarily much more sophisticated than at any other point in this report, and to bridge this gap, a mathematical review of gauge theory and moduli spaces has been included. An analysis of the geometry underlying Donaldson theory gives a general recipe for constructing field theories associated to moduli spaces in arbitrary dimensions, and as an example, we analyze in detail the super BF theories associated with flat connections. Chern-Simons theory and related BF models are the subject of section 6. The connections with knot theory are briefly reviewed and the link with 2D conformal field theory is sketched. We also consider 3D gravity from the Chern-Simons point of view. A presentation of the metric and gauge theory approaches to topological gravity in two dimensions is given. As in all quantum field theories, the issues of renormalization needs to be addressed, and one is obliged to show that the formal topological properties of these theories survive quantization. This point is considsurvive quantization. This point is considered in section 8. We present a detailed analysis of the beta function in certain Witten type theories, and compute one-loop effects in Chern-Simons theory. (orig./HSI)

Supersymmetric gauge theories from string theory  

International Nuclear Information System (INIS)

This thesis presents various ways to construct four-dimensional quantum field theories from string theory. In a first part we study the generation of a supersymmetric Yang-Mills theory, coupled to an adjoint chiral superfield, from type IIB string theory on non-compact Calabi-Yau manifolds, with D-branes wrapping certain sub-cycles. Properties of the gauge theory are then mapped to the geometric structure of the Calabi-Yau space. Even if the Calabi-Yau geometry is too complicated to evaluate the geometric integrals explicitly, one can then always use matrix model perturbation theory to calculate the effective superpotential. The second part of this work covers the generation of four-dimensional super-symmetric gauge theories, carrying several important characteristic features of the standard model, from compactifications of eleven-dimensional supergravity on G2-manifolds. If the latter contain conical singularities, chiral fermions are present in the four-dimensional gauge theory, which potentially lead to anomalies. We show that, locally at each singularity, these anomalies are cancelled by the non-invariance of the classical action through a mechanism called 'anomaly inflow'. Unfortunately, no explicit metric of a compact G2-manifold is known. Here we construct families of metrics on compact weak G2-manifolds, which contain two conical singularities. Weak G2-manifolds have properties that are similar to the ones of proper G2-manifolds, and hence the explicit examples might be useful to better understand the generic situation. Finally, we reconsider the relation between eleven-dimensional supergravity and the E8 x E8-heterotic string. This is done by carefully studying the anomalies that appear if the supergravity theory is formulated on a ten-manifold times the interval. Again we find that the anomalies cancel locally at the boundaries of the interval through anomaly inflow, provided one suitably modifies the classical action. (author)

Fivebranes from gauge theory  

International Nuclear Information System (INIS)

We study theories with 16 supercharges and a discrete energy spectrum. One class of theories has symmetry group SU(2|4). They arise as truncations of N=4 super Yang-Mills theory. They include the plane-wave matrix model, 2+1 super Yang-Mills theory on RxS2 and N=4 super Yang-Mills theory on RxS3/Zk. We explain how to obtain their gravity duals in a unified way. We explore the regions of the geometry that are relevant for the study of some 1/2 BPS and near BPS states. This leads to a class of two dimensional (4,4) supersymmetric sigma models with nonzero H flux, including a massive deformed WZW model. We show how to match some features of the string spectrum with the Yang-Mills theory. The other class of theories are also connected to N=4 super Yang-Mills theory and arise by making some of the transverse scalars compact. Their vacua are characterized by a 2D Yang-Mills theory or 3D Chern-Simons theory. These theories realize peculiar super-Poincare symmetry algebras in 2+1 or 1+1 dimensions with ''noncentral'' charges. We finally discuss gravity duals of N=4 super Yang-Mills theory on AdS3xS1

Politics, Security, Theory  

DEFF Research Database (Denmark)

This article outlines three ways of analysing the ‘politics of securitization’, emphasizing an often-overlooked form of politics practised through theory design. The structure and nature of a theory can have systematic political implications. Analysis of this ‘politics of securitization’ is distinct from both the study of political practices of securitization and explorations of competing concepts of politics among security theories. It means tracking what kinds of analysis the theory can produce and whether such analysis systematically impacts real-life political struggles. Securitization theory is found to ‘act politically’ through three structural features that systematically shape the political effects of using the theory. The article further discusses – on the basis of the preceding articles in the special issue – three emerging debates around securitization theory: ethics, transformations and post-Western analyses. The article finally suggests one possible way forward for securitization theory: a route built on first clarifying its concept of theory, then specifying more clearly the place of political theory and causal mechanisms in different parts of the analysis. The politics of securitization accordingly becomes sharpened. Instead of deducing the political quality of the theory from various empirical statements by its proponents, this approach zooms in on the very core of the theory: how does it structurally condition work done with it in systematically political ways?

In this article we review various applications of f(R theories to cosmology and gravity – such as inflation, dark energy, local gravity constraints, cosmological perturbations, and spherically symmetric solutions in weak and strong gravitational backgrounds. We present a number of ways to distinguish those theories from General Relativity observationally and experimentally. We also discuss the extension to other modified gravity theories such as Brans–Dicke theory and Gauss–Bonnet gravity, and address models that can satisfy both cosmological and local gravity constraints.

The David and Goliath principle: cultural, ideological, and attitudinal underpinnings of the normative protection of low-status groups from criticism.  

Science.gov (United States)

Two studies documented the "David and Goliath" rule--the tendency for people to perceive criticism of "David" groups (groups with low power and status) as less normatively permissible than criticism of "Goliath" groups (groups with high power and status). The authors confirmed the existence of the David and Goliath rule across Western and Chinese cultures (Study 1). However, the rule was endorsed more strongly in Western than in Chinese cultures, an effect mediated by cultural differences in power distance. Study 2 identified the psychological underpinnings of this rule in an Australian sample. Lower social dominance orientation (SDO) was associated with greater endorsement of the rule, an effect mediated through the differential attribution of stereotypes. Specifically, those low in SDO were more likely to attribute traits of warmth and incompetence to David versus Goliath groups, a pattern of stereotypes that was related to the protection of David groups from criticism.

An approach to systematically implement open-closed string duality for free large N gauge theories is summarised. We show how the relevant closed string moduli space emerges from a reorganization of the Feynman diagrams contributing to free field correlators. We also indicate why the resulting integrand on moduli space has the right features to be that of a string theory on AdS. (author)

Symmetries of renormalized theories. 2. Gauge theories  

International Nuclear Information System (INIS)

The symmetry properties of the renormalized general gauge theory (the symmetries besides the gauge one are implied) are studied in the general case, when the transformation jacobian-like quantities in the functional integral are not ignored. It is shown that if the classical action of gauge theory has additional symmetry, then the renormalized effective action and the renormalized generating functional of proper vertices also possess definite symmetry

Generalized descriptive set theory and classification theory  

OpenAIRE

Descriptive set theory is mainly concerned with studying subsets of the space of all countable binary sequences. In this paper we study the generalization where countable is replaced by uncountable. We explore properties of generalized Baire and Cantor spaces, equivalence relations and their Borel reducibility. The study shows that the descriptive set theory looks very different in this generalized setting compared to the classical, countable case. We also draw the connectio...

Matrix String Theory As A Generalized Quantum Theory  

OpenAIRE

Matrix String Theory of Banks, Fischler, Shenker and Susskind can be understood as a generalized quantum theory (provisionally named "quansical" theory) which differs from Adler's generalized trace quantum dynamics. The effective Matrix String Theory Hamiltonian is constructed in a particular fermionic realization of Matrix String Theory treated as an example of "quansical" theory.

High-precision surface analysis of the roughness of Michelangelo's David  

Science.gov (United States)

The knowledge of the shape of an artwork is an important element for its study and conservation. When dealing with a statue, roughness measurement is a very useful contribution to document its surface conditions, to assess either changes due to restoration intervention or surface decays due to wearing agents, and to monitor its time-evolution in terms of shape variations. In this work we present the preliminary results of the statistical analysis carried out on acquired data relative to six areas of the Michelangelo"s David marble statue, representative of differently degraded surfaces. Determination of the roughness and its relative characteristic wavelength is shown.

The harm of male-on-female rape: a response to David Benatar.

This article attacks David Benatar's claim made in his 2012 book, The Second Sexism: Discrimination Against Men and Boys, that when an individual is the victim of violence it does not matter whether his or her perpetrator is of the same or a different sex. By exploring two related yet distinct phenomena, well documented in the empirical psychological literature, that I call "shattering" and "fragmentation," I argue that when a woman is raped, it does matter that her rapist is male, given that her situation as a woman under patriarchy is partly constitutive of the harm that she suffers.

David Fabricius (1564-1617) was one of the most important astronomers in the period between 1596, the year of publication of Kepler's Mysterium cosmographicum, and 1609, the year of publication of the Astronomia nova.1 Kepler praised Fabricius as the most accurate observational astronomer after Tycho Brahe's death in 1601.2 Fabricius was a Reformed pastor in Ostfriesland (East Frisia), his remote natal region, and a vocational astronomer. He published nothing in the field of astronomy except for the short treatises between 1604 and 1606 concerning the nova that appeared in October 1604 in Serpentarius.

Gauge Theories of Gravitation  

CERN Document Server

During the last five decades, gravity, as one of the fundamental forces of nature, has been formulated as a gauge field theory of the Weyl-Cartan-Yang-Mills type. The resulting theory, the Poincar\\'e gauge theory of gravity, encompasses Einstein's gravitational theory as well as the teleparallel theory of gravity as subcases. In general, the spacetime structure is enriched by Cartan's torsion and the new theory can accommodate fermionic matter and its spin in a perfectly natural way. The present reprint volume contains articles from the most prominent proponents of the theory and is supplemented by detailed commentaries of the editors. This guided tour starts from special relativity and leads, in its first part, to general relativity and its gauge type extensions a la Weyl and Cartan. Subsequent stopping points are the theories of Yang-Mills and Utiyama and, as a particular vantage point, the theory of Sciama and Kibble. Later, the Poincar\\'e gauge theory and its generalizations are explored and specific topi...

Abstraction Super-structuring Normal Forms: Towards a Theory of Structural Induction  

CERN Document Server

Induction is the process by which we obtain predictive laws or theories or models of the world. We consider the structural aspect of induction. We answer the question as to whether we can find a finite and minmalistic set of operations on structural elements in terms of which any theory can be expressed. We identify abstraction (grouping similar entities) and super-structuring (combining topologically e.g., spatio-temporally close entities) as the essential structural operations in the induction process. We show that only two more structural operations, namely, reverse abstraction and reverse super-structuring (the duals of abstraction and super-structuring respectively) suffice in order to exploit the full power of Turing-equivalent generative grammars in induction. We explore the implications of this theorem with respect to the nature of hidden variables, radical positivism and the 2-century old claim of David Hume about the principles of connexion among ideas.

Quantum mechanics in the geometry of space-time. Elementary theory  

International Nuclear Information System (INIS)

This book continues the fundamental work of Arnold Sommerfeld and David Hestenes formulating theoretical physics in terms of Minkowski space-time geometry. We see how the standard matrix version of the Dirac equation can be reformulated in terms of a real space-time algebra, thus revealing a geometric meaning for the ''number i'' in quantum mechanics. Next, it is examined in some detail how electroweak theory can be integrated into the Dirac theory and this way interpreted in terms of space-time geometry. Finally, some implications for quantum electrodynamics are considered.The presentation of real quantum electromagnetism is expressed in an addendum. The book covers both the use of the complex and the real languages and allows the reader acquainted with the first language to make a step by step translation to the second one. (orig.)

The Global Approach to Quantum Field Theory  

International Nuclear Information System (INIS)

Parts I and II develop the basic classical and quantum kinematics of fields and other dynamical systems. The presentation is conducted in the utmost generality, allowing for dynamical quantities that may be anticommuting (supernumbers) and theories subject to the most general possible gauge symmetry. The basic ingredients are action functionals and the Peierls bracket, a manifestly covariant replacement for the Poisson bracket and equal-time commutation relations. For DeWitt the logical progression is Peierls bracket ? Schwinger action principle ? Feynman functional integral although he points out that the historical development was in the opposite order. It must be pointed out that the Peierls-Schwinger-DeWitt approach, despite some advantages over initial-value formulations, has some troubles of its own. In particular, it has never completely escaped from the arena of scattering theory, the paradigm of conventional particle physics. One is naturally led to study matrix elements between an 'in-vacuum' and an 'out-vacuum' though such concepts are murky in situations, such as big bangs and black holes, where the ambient geometry is not asymptotically static in the far past and future. The newest material in the treatise appears in two chapters in part II devoted to the interpretation of quantum theory, incorporating some unpublished work of David Deutsch on the meaning of probability in physics. Parts III through V apply the formalism in depth to successively more rmalism in depth to successively more difficult classes of systems: quantum mechanics, linear (free) fields, and interacting fields. DeWitt's characteristic tools of effective actions, heat kernels, and ghost fields are developed. Chapters 26 and 31 outline new approaches developed in collaboration with DeWitt's recent students C Molina-Paris and C Y Wang, respectively. The most of parts VI and VII consist of special topics, such as anomalies, particle creation by external fields, Unruh acceleration temperature, black holes, and Euclideanization. Chapter 30, on black holes and Hawking radiation, will be very familiar to readers of DeWitt's influential review article. Chapter 28, on anomalies, makes a careful distinction (missing from many treatments) between 'critical' anomalies, which render equations of motion inconsistent in the (would-be) quantum theory, and harmless anomalies that merely invalidate predictions that would classically follow from certain symmetries. Examples of critical anomalies are the chiral anomaly of a spinor field coupled to a non-Abelian gauge field and the anomaly in the conservation law of the stress tensor of certain pathological theories. DeWitt's chapter calculates the trace and chiral anomalies in detail. The last two chapters of part VII treat the most important particular quantum field theories. Chapter 34 develops many of the textbook predictions of quantum eletrodynamics from DeWitt's starting point. Chapter 35 covers Yang-Mills fields and quantum gravity. The discussion of gravity is surprisingly brief, in view of DeWitt's lifelong preoccupation with that subject. He rejects renormalizable fourth-order modifications of four-dimensional gravity because he could not stomach unfriendly ghosts (states of negative norm or unboundedly negative energy) nor the technical difficulties of integrating such theories into the functional-integral formalism. Finally, there is part VIII, entitled 'Examples. Simple Exercises in the Use of the Global Formalism'. It consists of 25 short chapters numbered separately from those of the main text. The preface recommends reading these and the main text in parallel. Most valuable in my opinion is a string of successively more complicated fermionic models. Hidden in an appendix is a crucial motivational paragraph: Super Hilbert spaces are generalizations of ordinary Hilbert spaces, designed so as to enable one to consider quantum systems with supernumber-valued parameters (e.g., a-type external sources) which, themselves, are introduced in order to present, in a compact algebraic way, certain rel

Imperi coloniali da Oriente a Occidente: immagini dell’Altro da Tacito a David Malouf, da Salman Rushdie a Michael Ondaatje  

Directory of Open Access Journals (Sweden)

Full Text Available Many centuries before Joseph Conrad’s Heart of Darkness (1902 and Rudyard Kipling’s Kim (1901 were published, the East and West were still divided, as in Tacito’s De Germania, by a limes also visible in David Malouf’s An Imaginary Life (1978, in which the poet Ovid exiled at Tomi, is friends with the savage Child, of animal nature in a human body, similar to the metamorphic migrants of Salman Rushdie’s The Satanic Verses (1988, which hides the magnificent and ancient East of Mah?bh?rata and R?m?yana in many Western identities, lost in diabolic European cities. This chaotic antithesis in Michael Ondaatje’s pages lets Sri Lanka’s childish ghosts float amidst stories of peregrination and in search of a Promised Land. In the Skin of a Lion (1987 includes an epigraph from the ancient poem of Gilgamesh, an Eastern echo in a novel profoundly important for many Western studies that often focus on the theory of the canon or on postmodern literature. These categories are discussed with the prospect of broadening cultural and post-colonial studies, in order to merge theory of genres and thematic criticism with anthropology, mythology, and ethnology. Multiple citations expand the original object of research, adding the colonial prophecy present in North American myths, as demonstrated by Margaret Atwood, Margaret Laurence or Lévi-Strauss. Incessantly moving from one space to another, authors give voice to the native cry from multiple perspectives, narrating – like all colonial empires founded on human cruelty– the beast’s nature that has shown its worst aspect.

Stationary scattering theory  

International Nuclear Information System (INIS)

A complementary approach to the time dependent scattering theory for one-body Schroedinger operators is presented. The stationary theory is concerned with objects of quantum theory like scattering waves and amplitudes. In the more recent abstract stationary theory some generalized form of the Lippman-Schwinger equation plays the basic role. Solving this equation leads to a linear map between generalized eigenfunctions of the perturbed and unperturbed operators. This map is the section at fixed energy of the wave-operator from the time dependent theory. Although the radiation condition does not appears explicitely in this formulation it can be shown to hold a posteriori in a variety of situations thus restoring the link with physical theories

Is string theory true?  

International Nuclear Information System (INIS)

String theory allows physicists to unify the 4 basic interactions, gravity included. This theory assumes that each elementary particle is represented by a string that vibrates in a 9-dimension space. One success of this theory concerns black holes. In 1997 a group of physicists developed a model based on string theory that yielded a theoretical result that had been discovered 20 years earlier: any black hole is a low intensity source of radiation due to quantum processes. String theory lacks experimental confirmations but some predictions could be tested in the LHC (large hadron collider) that is planned to be put in service in 2005. String theory implies supersymmetry, it means that each particle has a counterpart particle called sparticle that is much heavier, these sparticles might be detected in the next generation of particle accelerators.

F-theory Superspace  

CERN Document Server

We consider, at the linearized level, the superspace formulation of lower-dimensional F-theory. In particular, we describe the embedding of 3D Type II supergravity of the superstring, or 4D, N=1 supergravity of M-theory, into the corresponding F-theory in full detail, giving the linearized action and gauge transformations in terms of the prepotential. This manifestly supersymmetric formulation reveals some features not evident from a component treatment, such as Weyl and local S-supersymmetry invariances. The linearized multiplet appears as a super 3-form (just as that for the manifestly T-dual theory is a super 2-form), reflecting the embedding of M-theory (as the T-dual theory embeds Type II supergravity). We also give the embedding of matter multiplets into this superspace, and derive the F-constraint from the gauge invariance of the gauge invariance.

Corpses of Metaphor. Images of Death in David Leavitt and Jamaica Kincaid  

Directory of Open Access Journals (Sweden)

Full Text Available This essay analyzes two works, My Brother by Jamaica Kincaid, and "Saturn Street" by David Leavitt, investigating the construction of homosexuality as a process accomplished by resorting to illness (AIDS and death. In both works, indeed, the slow and dramatic course of AIDS amounts to the progressive unveiling of homosexuality as a social threat or a cause of anxiety and repulsion. The two works are set in different contexts: whereas Jamaica Kincaid refers to the problematic situation of homosexuality in the Caribbean, David Leavitt explores the social and cultural scenario of the 1990s Los Angeles, in the wake of a by now ended utopian confidence in science and technology.  This comparative approach helps us understand the political dynamics through which, in different and, to some extents, opposite realities, the social stigma of AIDS worked as a means to construct homosexual identity and set it apart from the sanitized spectrum of normal and sanctioned sexual behaviors. The point I want to make in this essay is that the corpse is used as an effective metaphor for a dehumanized depiction of male homosexual and ill subjects.

Almost quantum theory  

OpenAIRE

Modal quantum theory (MQT) is a "toy model" of quantum theory in which amplitudes are elements of a general field. The theory predicts, not the probabilities of a measurement result, but only whether or not a result is possible. In this paper we review MQT and extend it to include mixed states, generalized measurements and open system dynamics. Even though MQT does not have density operators, superoperators or any concept of "positivity", we can nevertheless establish a prec...

Twisted $K$-theory  

OpenAIRE

Twisted complex $K$-theory can be defined for a space $X$ equipped with a bundle of complex projective spaces, or, equivalently, with a bundle of C$^*$-algebras. Up to equivalence, the twisting corresponds to an element of $H^3(X;\\Z)$. We give a systematic account of the definition and basic properties of the twisted theory, emphasizing some points where it behaves differently from ordinary $K$-theory. (We omit, however, its relations to classical cohomology, which we shall ...

Class field theory from theory to practice  

CERN Document Server

Global class field theory is a major achievement of algebraic number theory, based on the functorial properties of the reciprocity map and the existence theorem. The author works out the consequences and the practical use of these results by giving detailed studies and illustrations of classical subjects (classes, idèles, ray class fields, symbols, reciprocity laws, Hasse's principles, the Grunwald-Wang theorem, Hilbert's towers,...). He also proves some new or less-known results (reflection theorem, structure of the abelian closure of a number field) and lays emphasis on the invariant (/cal T) p, of abelian p-ramification, which is related to important Galois cohomology properties and p-adic conjectures. This book, intermediary between the classical literature published in the sixties and the recent computational literature, gives much material in an elementary way, and is suitable for students, researchers, and all who are fascinated by this theory. In the corrected 2nd printing 2005, the author improves s...

Empirical comparison of theories  

International Nuclear Information System (INIS)

The book represents the first, comprehensive attempt to take an empirical approach for comparative assessment of theories in sociology. The aims, problems, and advantages of the empirical approach are discussed in detail, and the three theories selected for the purpose of this work are explained. Their comparative assessment is performed within the framework of several research projects, which among other subjects also investigate the social aspects of the protest against nuclear power plants. The theories analysed in this context are the theory of mental incongruities and that of the benefit, and their efficiency in explaining protest behaviour is compared. (orig./HSCH)

Portfolio Theory Forward Testing  

Directory of Open Access Journals (Sweden)

Full Text Available Portfolio Theory has during many decades been considered as the holy grail of investment despite the fact that very few empirical studies in the public domain have shown that portfolio theory outperforms a random equal weighted portfolio. We will in this paper empirically investigate how successful portfolio theory is when it comes to generating large positive returns with low return volatility. The dataset that is used consists of approximately 4000 US stocks. We find weak support that portfolio theory by itself would have generated any returns different than a random portfolio allocation. In general optimized historical cumulative returns are not the same as forward cumulative returns.

Kaluza--Klein theory  

International Nuclear Information System (INIS)

Assuming the compactification of 4+K-dimensional space-time implied in Kaluza--Klein-type theories, we consider the case in which the internal manifold is a quotient space, G/H. We develop normal mode expansions on the internal manifold and show that the conventional gravitational plus Yang-Mills theory (realizing local G symmetry) is obtained in the leading approximation. The higher terms in the expansions give rise to field theories of massive particles. In particular, for the original Kaluza--Klein 4+1-dimensional theory, the higher excitations describe massive, charged, purely spin-2 particles. These belong to infinite dimensional representations of an O

Introduction to string theory  

International Nuclear Information System (INIS)

Open and closed boson theories are discussed in a classical framework, highlighting the physical interpretation of conformal symmetry and the Virasoro (1970) algebra. The quantification of bosonic strings is done within the old covariant operational formalism. This method is much less elegant and powerful than the BRST quantification, but it quickly reveals the physical content of quantum theory. Generalization to theories with fermionic degrees of freedom is introduced: the Neveu-Schartz (1971) and Ramond (1971) models, their reduced supersymmetry (two dimensions) and the Gliozzi, Scherk and Olive (1977) projection which leads to a supersymmetry theory in the usual meaning of the term

[United theory of aging].  

Science.gov (United States)

In attempts to develop a means of life prolongation the humankind has created more than three hundred theories of the aging; each of them offers the original cause of aging. However, none of them has given practical result by now. The majority of the theories have now only historical interest. There are several different theories that are mainly under consideration currently. They are based on reliable, proven evidence: the free radical theory, the protein error theory, the replicative senescence theory, the theory of reparation weakening, the immunological theory, several versions of neuroendocrinal theories, and programmed aging theory. The theory presented here is based on conception that the life as the phenomenon represents many of the interconnected physical and chemical processes propelled by energy of the mitochondrial bioenergetical machine. Gradual degradation of all vital processes is caused by the programmed decrease in level of bioenergetics. This theory unites all existing theories of aging constructed on authentic facts: it is shown, that such fundamental phenomena accompanying aging process as the increase in level of reactive oxygen species (ROS), the decrease in the general level of protein synthesis, the limitation of cellular dividing (Haiflick limit), decrease in efficiency of reparation mechanisms are caused by bioenergetics attenuation. Each of these phenomena in turn generates a number of harmful secondary processes. Any of the theories bases on one of these destructive phenomena or their combination. Hence, each of them describes one of sides of process of the aging initially caused by programmed decrease of level of bioenergetics. This united theory gives the chance to understand the nature of aging clock and explains a phenomenon of increase in longevity at the condition of food restriction. Failures of attempts to develop means from aging are explained by that the manipulations with the separate secondary phenomena of attenuation of bioenergetics, now in use, are not capable to advance longevity beyond the bounds of its natural duration. There is only one way to achieve an unlimited healthy life--to find a way of bioenergetics management. PMID:23734500

Rotor theories by Professor Joukowsky: Momentum theories  

DEFF Research Database (Denmark)

This paper is the first of two papers on the history of rotor aerodynamics with special emphasis on the role of Joukowsky. The present one focuses on the development of the momentum theory while the second one surveys the development of vortex theory for rotors. Joukowsky has played a major role in these developments. Although he cooperated with other famous aerodynamicists like Prandtl, his contribution is not well recognized as most of his publications are in Russian. The paper discusses the role of the English, Russian and German research schools in the beginning of the Twentieth Century, and the contributions by individual researchers like Lanchester, Prandtl, Betz and Joukowslcy himself. After the one-dimensional momentum theory was well established, the introduction of torque and angular momentum was the next step. Joukowslcy has led the basis for this step, but Glauert's Blade Element Momentum still is the basis of current rotor design codes. He applied some assumptions limiting the validity to moderate and high tip speed ratios. Sorensen and van Kuik published a solution for wind turbines with very low tip speed ratios, which is now expanded to propellers as well, with one remaining assumption of inviscid flow. For very low tip speed ratios the general momentum theory gives unphysical results which disappear after applying a perturbation parameter representing phenomena not captured by the Euler equations.

Generic probabilistic theories : reconstruction of quantum theory  

International Nuclear Information System (INIS)

This thesis is a collection of projects done under supervision of Prof. Caslav Brukner. It is divided into two main chapters. First part is based on the instrumental approach to quantum mechanics with the main objective to identify and mark the exclusive features of quantum theory in a broad class of probabilistic theories. The second part investigates the non-classical features of quantum mechanics including quantum statistics, quantum correlations and quantum simulations. It is fair to say that we still lack intuitive clear and broadly accepted physical principles that are a groundbasis of quantum theory. This shortfall is the main reason for todays coexistence of various interpretations of quantum theory, some of which even use mutually exclusive concepts. One of the main objectives in the first chapter was to specify theories that describe systems with fundamentally limited information content and therefore necessarily give a probabilistic description. With 'limited information content of the system' we understand a fundamental restriction on how much information about the state preparation can be decoded in the measurement. What was found is the whole hierarchy of theories that share this property with quantum and classical probability theory. The two theories separate from the full class of the probabilistic theories by adopting additional assumptions: locality and reversibility. With the 'locality' principle we assume that a global state of a composite system chat a global state of a composite system can be learned trough the statistics of individual systems, whereas the 'reversibility' principle states that any two pure state can be connected by a reversible transformation. Finally, quantum theory is separated by the requirement that the set of reversible transformations is continuous. In addition, one of the basic quantum concepts, the complementarity principle was investigated through so- called mutually unbiased bases relating them to the known mathematical problem of orthogonal Latin squares. A plausible classical description of quantum statistics requires counterintuitive concepts such as 'quantum non-locality' and contextuality'. The part of the second chapter deals with another question, i.e. the 'cost' in terms of resources for a plausible classical description. It was found that classical simulation of quantum statistics requires a polynomial number of classical resources (hidden-variables) in terms of number of measurement settings. Furthermore, the model confirms, in a proper limit, the known result that quantum mechanics is indeed the most optimal description of itself. Quantum correlations are responsible for 'quantum non-locality', as well as computational speedups and quantum information processing. There are examples of quantum information tasks that do not necessarily require entanglement. Therefore it is fair to say that 'quantumness' of the correlations is not equivalent to entanglement. The part of the second chapter deals with the question of 'non-classicality' of quantum correlations, captured by quantum discord. The main result gives an experimentally friendly necessary and sufficient condition for non-zero quantum discord. Furthermore the analysis of the resources in a mixed-state quantum computation scenario is provided and shows that the role of quantum discord in quantum information processing still remains unclear. Finally, the part of the last chapter investigates quantum simulations, both theoretically and experimentally. Quantum simulators provide a platform to mimic the dynamics of another quantum system that is infeasible for simulations on a classical computer. What is presented is the framework for the experimental realization of a small-size photonic quantum simulator that is capable of simulating a frustrated spin tetramer. The full dynamics and simulation of the ground state adiabatic evolution is achieved by employing entangled photon pairs, tunable quantum gates and measurement induced nonlinearities. (author)

The Theory Of Gravity  

CERN Document Server

In the framework of the special theory of relativity, the relativistic theory of gravitation (RTG) is constructed. The energy-momentum tensor density of all the matter fields (including gravitational one) is treated as a source of the gravitational field. The energy-momentum and the angular momentum conservation laws are fulfilled in this theory. Such an approach permits us to unambiguously construct the gravitional field theory as a gauge theory. According to the RTG, the homogeneous and isotropic Universe is to be ``flat''. It evolves cyclewise from some maximal density to the minimal one, etc. The book is designed for scientific workers, post-graduates and upper-year students majoring in theoretical physics.

Action Theory Evolution  

CERN Document Server

Like any other logical theory, domain descriptions in reasoning about actions may evolve, and thus need revision methods to adequately accommodate new information about the behavior of actions. The present work is about changing action domain descriptions in propositional dynamic logic. Its contribution is threefold: first we revisit the semantics of action theory contraction that has been done in previous work, giving more robust operators that express minimal change based on a notion of distance between Kripke-models. Second we give algorithms for syntactical action theory contraction and establish their correctness w.r.t. our semantics. Finally we state postulates for action theory contraction and assess the behavior of our operators w.r.t. them. Moreover, we also address the revision counterpart of action theory change, showing that it benefits from our semantics for contraction.

G2 gauge theories  

CERN Document Server

QCD can be formulated using any gauge group. One particular interesting choice is to replace SU(3) by the exceptional group G2. Conceptually, this group is the simplest group with a trivial center. It thus permits to study the conjectured relevance of center degrees of freedom for QCD. Practically, since all its representation are real, it is possible to perform lattice simulations for this theory also at finite baryon densities. It is thus an excellent environment to test methods and to investigate general properties of gauge theories at finite densities. We review the status of our understanding of gauge theories with the gauge group G2, including Yang-Mills theory, Yang-Mills-Higgs theory, and QCD both in the vacuum and in the phase diagram.

Nonlinear spectral theory  

CERN Document Server

In view of the eminent importance of spectral theory of linear operators in many fields of mathematics and physics, it is not surprising that various attempts have been made to define and study spectra also for nonlinear operators. This book provides a comprehensive and self-contained treatment of the theory, methods, and applications of nonlinear spectral theory. The only prerequisite for understanding this book is a modest background in functional analysis and operator theory. It is addressed to non-specialists who want to get an idea of the development of spectral theory for nonlinear operators in the last 30 years, as well as a glimpse of the diversity of the directions in which current research is moving.

Statistical theory and inference  

CERN Document Server

This text is for  a one semester graduate course in statistical theory and covers minimal and complete sufficient statistics, maximum likelihood estimators, method of moments, bias and mean square error, uniform minimum variance estimators and the Cramer-Rao lower bound, an introduction to large sample theory, likelihood ratio tests and uniformly most powerful  tests and the Neyman Pearson Lemma. A major goal of this text is to make these topics much more accessible to students by using the theory of exponential families. Exponential families, indicator functions and the support of the distribution are used throughout the text to simplify the theory. More than 50 ``brand name" distributions are used to illustrate the theory with many examples of exponential families, maximum likelihood estimators and uniformly minimum variance unbiased estimators. There are many homework problems with over 30 pages of solutions.

Theory of gravitational interactions  

CERN Document Server

This reference textbook is an up-to-date and self-contained introduction to the theory of gravitational interactions. The first part of the book follows the traditional presentation of general relativity as a geometric theory of the macroscopic gravitational field. A second, advanced part then discusses the deep analogies (and differences) between a geometric theory of gravity and the gauge theories of the other fundamental interactions. This fills a gap which is present in the context of the traditional approach to general relativity, and which usually makes students puzzled about the role of gravity. The necessary notions of differential geometry are reduced to the minimum, leaving more room for those aspects of gravitational physics of current phenomenological and theoretical interest, such as the properties of gravitational waves, the gravitational interactions of spinors, and the supersymmetric and higher-dimensional generalization of the Einstein equations. Theory of Gravitational Interactions will be o...

Nonlocal continuum field theories  

CERN Document Server

Nonlocal continuum field theories are concerned with material bodies whose behavior at any interior point depends on the state of all other points in the body -- rather than only on an effective field resulting from these points -- in addition to its own state and the state of some calculable external field. Nonlocal field theory extends classical field theory by describing the responses of points within the medium by functionals rather than functions (the "constitutive relations" of classical field theory). Such considerations are already well known in solid-state physics, where the nonlocal interactions between the atoms are prevalent in determining the properties of the material. The tools developed for crystalline materials, however, do not lend themselves to analyzing amorphous materials, or materials in which imperfections are a major part of the structure. Nonlocal continuum theories, by contrast, can describe these materials faithfully at scales down to the lattice parameter. This book presents a unif...

Alternative gravity theories  

International Nuclear Information System (INIS)

Although general relativity is a well-established discipline the theory deserves efforts aimed at producing alternative or more general frameworks for investigating the classical properties of gravity. These are either devoted to producing alternative viewpoints or interpretations of standard general relativity, or at constructing, discussing and proposing experimental tests for alternative descriptions of the dynamics of the gravitational field and its interaction (or unification) with external matter fields. Classical alternative theories of gravitation can roughly classified as follows; theories based on a still 4-dimensional picture, under the assumption that the dynamics of the gravitational field is more complicated than Einstein's and theories based on higher-dimensional pictures. This leads to supergravity and strings which are not included here. Theories based on higher-dimensional pictures on the assumption that space-time is replaced by a higher-dimensional manifold. Papers on these classifications are reviewed. (author)

Constructor Theory of Life  

CERN Document Server

Neo-Darwinian evolution theory explains how organisms with their appearance of purposive design came into existence without being designed. The centrepiece of the explanation is a physical object, the gene, and the processes it undergoes: mainly, replication and natural selection. The compatibility of that theory with the laws of physics has been challenged, by claims that self-reproduction of living cells, essential to gene replication, is incompatible with quantum theory. Wigner, notably, argued that it would require design-bearing laws of physics. Here I show that self-reproduction is compatible with no-design laws of physics, in particular with quantum theory, by expressing self-reproduction, replication and the appearance of design clearly within physics, using the recently proposed constructor theory. I also show that aside from sufficient resources such as time and energy, the only requirement on the laws of physics for evolution to be possible is that they permit digital information.

Lattice Gerbe Theory  

CERN Document Server

We formulate the theory of a 2-form gauge field on a Euclidean spacetime lattice. In this approach, the fundamental degrees of freedom live on the faces of the lattice, and the action can be constructed from the sum over Wilson surfaces associated with each fundamental cube of the lattice. If we take the gauge group to be $U(1)$, the theory reduces to the well-known abelian gerbe theory in the continuum limit. We also propose a very simple and natural non-abelian generalization with gauge group $U(N) \\times U(N)$, which gives rise to $U(N)$ Yang-Mills theory upon dimensional reduction. Formulating the theory on a lattice has several other advantages. In particular, it is possible to compute many observables, such as the expectation value of Wilson surfaces, analytically at strong coupling and numerically for any value of the coupling.

W???????? ??? : A propos du roman inédit de David Vogel en yiddish “W ??? ???????” : About David Vogel’s unpublished novel in Yiddish ??????? ??? W : ????? ??? ???????? ????–??????????????? ??????? ???????  

Directory of Open Access Journals (Sweden)

Full Text Available At the beginning of the 1940s, Hebrew writer David Vogel (1891-1944 started to write a Yiddish novel for the first time. As an Austrian citizen living in France, he had been held in a camp for suspicious foreigners. His narrative, inspired by this experience, remained untitled after he was captured and sent to death by the Gestapo at the beginning of 1944. Its original version has never been published.This article gives an overview of critical approaches to this text that have been published up to now. It proposes an analysis based on Merleau-Ponty’s linguistic thought and on the principles of literary genetics. The manuscript, with its deletions and additions, is approached in the light of all the languages in which the author could have written in and that leave their mark on the narrative. The author of this article argues that the poetics of foreign language is more central than the question of Vogel’s linguistic identity. His writing in Yiddish thus poses the problem of the status of this language in a world where things are no longer called what they were.??????? 40?? ????? ???? ??? ?????????? ??????? ??? ???????

De David Belasco à Giacomo Puccini : La Fanciulla del West, premier opéra « américain » From David Belasco to Giacomo Puccini:La Fanciulla del West, first “American” opera  

Directory of Open Access Journals (Sweden)

Full Text Available La Fanciulla del West is a “horse opera” resulting from the second collaboration between David Belasco and Giacomo Puccini. This work, specially composed for the American stage, which had its world premiere at New York’s Metropolitan Opera in December 1910, paved the way for American composers who increasingly focused on American History in their quest for a “national” opera. For the first time, Puccini resorted to genuine Indian music, a Zuni melody, which he re-elaborated for dramatic purposes and associated with the nostalgic mood of uprooted people, the miners who left their home country for America. The Other – the native American viewed from the vantage point of the white, as well as the foreigner – no longer represented a threat, as had been the case in the operatic repertoire before, but became part and parcel of a multicultural society, like the Italian immigrant to whom Puccini also paid tribute. The Zuni melody, which opens and closes the opera, contributes to giving a genuine twist to a score which is the first one to tackle the foundations of the American nation.

Gauge field theory  

International Nuclear Information System (INIS)

This lecture is devoted to the discussion of gauge field theory permitting from the single point of view to describe all the interactions of elementary particles. The authors used electrodynamics and the Einstein theory of gravity to search for a renormgroup fixing a form of Lagrangian. It is shown that the gauge invariance added with the requirement of the minimum number of arbitraries in Lagrangian fixes unambigously the form of the electromagnetic interaction. The generalization of this construction for more complicate charge spaces results in the Yang-Mills theory. The interaction form in this theory is fixed with the relativity principle in the charge space. A quantum scheme of the Yang-Mills fields through the explicit separation of true dynamic variables is suggested. A comfortable relativistically invariant diagram technique for the calculation of a producing potential for the Green functions is described. The Ward generalized identities have been obtained and a procedure of the elimination of ultraviolet and infrared divergencies has been accomplished. Within the framework of QCD (quantum-chromodynamic) the phenomenon of the asymptotic freedom being the most successful prediction of the gauge theory of strong interactions was described. Working methods with QCD outside the framework of the perturbation theory have been described from a coupling constant. QCD is represented as a single theory possessing both the asymptotical freedom and the freedom retaining quarks

On geometrized gravitation theories  

International Nuclear Information System (INIS)

General properties of the geometrized gravitation theories have been considered. Geometrization of the theory is realized only to the extent that by necessity follows from an experiment (geometrization of the density of the matter Lagrangian only). Aor a general case the gravitation field equations and the equations of motion for matter are formulated in the different Riemann spaces. A covariant formulation of the energy-momentum conservation laws is given in an arbitrary geometrized theory. The noncovariant notion of ''pseudotensor'' is not required in formulating the conservation laws. It is shown that in the general case (i.e., when there is an explicit dependence of the matter Lagrangian density on the covariant derivatives) a symmetric energy-momentum tensor of the matter is explicitly dependent on the curvature tensor. There are enlisted different geometrized theories that describe a known set of the experimental facts. The properties of one of the versions of the quasilinear geometrized theory that describes the experimental facts are considered. In such a theory the fundamental static spherically symmetrical solution has a singularity only in the coordinate origin. The theory permits to create a satisfactory model of the homogeneous nonstationary Universe

[Life-cycle of Renicola lari J. Timon-David, 1933 (Trematoda, Renicolidae) (author's transl)].  

Science.gov (United States)

This paper deals with life-cycle of Renicola lari J. Timon-David, 1933. Description and illustration are given. Sporocyst development occurs inside the visceral mass of Cerithium mediterraneum and C. Rupestre (Mollusca Prosobranchia). Cercariae are planktonic; they are swallowed up by the second intermediate host, Atherina hepsetus and A. boyeri (Teleostean fishes). Cercariae perforate intestine wall. Metacercariae are encysted in liver. Adult flukes have been recovered in kidneys of uninfected Larus argentatus and L. ridibundus after exerimental contamination with naturally infected fishes. Cercariae of Renicola lari differ from Plagiorchid type cercariae by the following characters : stylet lacking ; very large excretory bladder ; they develop into metacercariae in fishes. Cercariae of R. lari seem to Rhodometope type cercariae ; they have the same excretory bladder. Cercariae of R. lari differ from Rhodometope cercariae in lacking fins on their tail. PMID:754615

A Map Worth Glancing At : A Conversation on Utopias with David Pinder  

DEFF Research Database (Denmark)

“There is no alternative”, Margaret Thatcher infamously stated as an argument for capital- ism in its most liberal form – despite its obvious shortcomings – as the only relevant eco- nomic system in advanced and modern democracies. With the demise of state socialism in the 1990s for a time it seemed like she had been right, and more and more in urban planning and design today, the market forces seem at least as important as the human condition. But why is it meant to be unrealistic to propose decent housing for all or an urbanism that puts the needs of people above those of profit? And what is inconceivable about an urbanism that is no longer based around private property, or that emphasises the pleasures and joys of living? In this e-mail conversation the British geographer David Pinder makes a defence for utopian thinking as a means to imagine alternatives that seem impossible today but may be possible tomorrow

Animals and nature: mapping storylines and metaphors in David Kramer’s narratives  

Directory of Open Access Journals (Sweden)

Full Text Available This article discusses the representation of animals and nature in selected lyrics from the oeuvre of singer, songwriter and producer David Kramer and considers his engagement with historical and contemporary discourses about human-animal and human-nature interaction in relation to ecological awareness within a South African context. I trace the socio-political commentary voiced through his depiction of animals in the folksongs he wrote during apartheid, especially in lyrics from the album “Baboondogs” (Kramer, 1986. Kramer also employs intertextual references to traditional South African folksongs and tales in his music. Furthermore, the social and environmental significance of Kramer’s representations of nature in a selection of his postapartheid lyrics is investigated. I argue that the pedagogical value of Kramer’s cultural commentary can contribute significantly to the challenge of teaching animal studies and ecocriticism in South African context.

Section 1: Monitoring the global carbon cycle: A tribute to Charles David Keeling  

Science.gov (United States)

The CO2 concentration of our atmosphere is increasing. This fact was detected by Charles David Keeling after he designed and deployed his program of CO2 measurements at Mauna Loa and Antarctica in the 1950s. These measurements continue to this day in collaboration with the National Oceanic and Atmospheric Administration. Their cumulative display—updated regularly—is often known as the Keeling Curve. More than any other scientific record, this graph has motivated the growing level of public concern that has now made carbon sequestration a commonly-known concept. Can carbon sequestration help reverse the trend shown in the Keeling Curve? The challenge of this question is the reason this book was assembled.

The Dehumanizing American Dream in David Mamet’s Glengarry Glen Ross  

Directory of Open Access Journals (Sweden)

Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on the human spirit. It is also shown, through the analysis of David Mamet’s glengarry Glen Ross, that despite the promise of the dream it contains many contradictions. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, for instance, as  the most prominent of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life.

David Lewis’s Neglected Challenge: It’s Me or God  

Directory of Open Access Journals (Sweden)

Full Text Available I begin by sketching a dialectic typical of modern discussions of the ontological argument and explain the underlying modal principles. I will not pursue this well-worn dialectic. Instead I will explicate David Lewis’s valid reconstruction (in first order predicate logic of St Anselm’s argument in Proslogion-II. Lewis’s objections to this argument are based on his idiosyncratic views about modality. Implicitly, Lewis presents a challenge: either I am right about modality, or there is a sound version of the ontological argument. More specifically, Lewis claims there is no good reason to supposethere is anything special about the actual world. I suggest there is good reason to think that must be incorrect. Thus we are left with a formal version of the ontological argument for God’s existence that for all we have seen here looks eminently viable.

Reply to "Nonlocality and Bohr's Reply to EPR" (N David Mermin)  

CERN Document Server

David Mermin's recent paper with the same title as this one makes it clear that his claim to have found a gap in my reasoning rests on his claim that my argument violates a criterion for meaningfulness of counterfactual statements that I myself had set down. I set down no such requirement. But I am willing to accept it as a conservative sufficient condition. This already entails, within my proof, that nature must have a deep structure that extends beyond what actually occurs. It imposes, without appeal to the notion of determinism or hidden variables, constraints connecting, at the macroscopic level, what did occur to what would have occurred if certain quantum choices had gone differently. All the statements in the proof have natural meanings within the context of an examination of that deep structure.

Massive IIA string theory and Matrix theory compactification  

International Nuclear Information System (INIS)

We propose a Matrix theory approach to Romans' massive Type IIA supergravity. It is obtained by applying the procedure of Matrix theory compactifications to Hull's proposal of the massive Type IIA string theory as M-theory on a twisted torus. The resulting Matrix theory is a super-Yang-Mills theory on large N three-branes with a space-dependent noncommutativity parameter, which is also independently derived by a T-duality approach. We give evidence showing that the energies of a class of physical excitations of the super-Yang-Mills theory show the correct symmetry expected from massive Type IIA string theory in a lightcone quantization

Gauge theories in local causal perturbation theory  

CERN Document Server

In this thesis quantum gauge theories are considered in the framework of local, causal perturbation theory. Gauge invariance is described in terms of the BRS formalism. Local interacting field operators are constructed perturbatively and field equations are established. A nilpotent BRS transformation is defined on the local algebra of fields. It allows the definition of the algebra of local observables as an operator cohomology. This algebra of local observables can be represented in a Hilbert space. The interacting field operators are defined in terms of time ordered products of free field operators. For the results above to hold the time ordered products must satisfy certain normalization conditions. To formulate these conditions also for field operators that contain a spacetime derivative a suitable mathematical description of time ordered products is developed. Among the normalization conditions are Ward identities for the ghost current and the BRS current. The latter are generalizations of a normalizatio...

Quasirelativistic theory. II. Theory at matrix level.  

Science.gov (United States)

The Dirac operator in a matrix representation in a kinetically balanced basis is transformed to the matrix representation of a quasirelativistic Hamiltonian that has the same electronic eigenstates as the original Dirac matrix (but no positronic eigenstates). This transformation involves a matrix X, for which an exact identity is derived and which can be constructed either in a noniterative way or by various iteration schemes, not requiring an expansion parameter. Both linearly convergent and quadratically convergent iteration schemes are discussed and compared numerically. The authors present three rather different schemes, for each of which even in unfavorable cases convergence is reached within three or four iterations, for all electronic eigenstates of the Dirac operator. The authors present the theory both in terms of a non-Hermitian and a Hermitian quasirelativistic Hamiltonian. Quasirelativistic approaches at the matrix level known from the literature are critically analyzed in the frame of the general theory. PMID:17381196

The main issue of this talk is whether cosmology indicates new physics beyond the standard $SU(3)\\times SU(2)\\times U(1)$ model with minimal particle content. The answer to this question is strongly and definitely "YES". New, yet unknown, physics exists and cosmology presents very weighty arguments in its favor.

The first objective is to analyse whether the SERVQUAL scale is an appropriate scale to quantify service quality and customer satisfaction of automobile-insurances. The second objective is to discuss the relationship between service quality and customer satisfaction. With the prospect theory, the relationship is explained and described. Only a negative asymmetric relationship between service quality and customer satisfaction can be explained by the prospect theory. The proposed diminishing sensitivity lacks sufficient significant empirical evidence.

Economic Selection Theory  

DEFF Research Database (Denmark)

The present article provides a minimal description of the causal structure of economic selection theory and outlines how the internal selection dynamics of business organisations can be reconciled with selection in competitive markets. In addition to generic similarity in terms of the Darwinian principles of variation, continuity and selection, it is argued that economic selection theory should mimic the causal structure of neo-Darwinian theory. Two of the most influential explanations of economic evolution, Alchian's and Nelson and Winter's, are used to illustrate how this could be achieved.

Rotational relativity theory  

International Nuclear Information System (INIS)

The constancy of the spin of the photon was recently shown to lead to a new Lorentz-type transformation that relates the energy, rotational velocity, momentum of inertia, and angular momentum, where rotational invariance was the basis of the theory instead of the ordinary linear invariance of special relativity. In this paper the new group of transformations is shown to lead naturally to a special theory of relativity whose basic metric has an RxS3 topology rather than the familiar Minkowskian metric. Predictions by the theory are shown to be highly supported by experiment. (author)

Renormalization of gauge theories  

International Nuclear Information System (INIS)

Gauge theories are characterized by the Slavnov identities which express their invariance under a family of transformations of the supergauge type which involve the Faddeev Popov ghosts. These identities are proved to all orders of renormalized perturbation theory, within the BPHZ framework, when the underlying Lie algebra is semisimple and the gauge function is chosen to be linear in the fields in such a way that all fields are massive. An example, the SU2 Higgs Kibble model is analyzed in detail: the asymptotic theory is formulated in the perturbative sense, and shown to be reasonable, namely, the physical S operator is unitary and independent from the parameters which define the gauge function

Field-theory methods in coagulation theory  

International Nuclear Information System (INIS)

Coagulating systems are systems of chaotically moving particles that collide and coalesce, producing daughter particles of mass equal to the sum of the masses involved in the respective collision event. The present article puts forth basic ideas underlying the application of methods of quantum-field theory to the theory of coagulating systems. Instead of the generally accepted treatment based on the use of a standard kinetic equation that describes the time evolution of concentrations of particles consisting of a preset number of identical objects (monomers in the following), one introduces the probability W(Q, t) to find the system in some state Q at an instant t for a specific rate of transitions between various states. Each state Q is characterized by a set of occupation numbers Q = (n1, n2, ..., ng, ...), where ng is the total number of particles containing precisely g monomers. Thereupon, one introduces the generating functional ? for the probability W(Q, t). The time evolution of ? is described by an equation that is similar to the Schrödinger equation for a one-dimensional Bose field. This equation is solved exactly for transition rates proportional to the product of the masses of colliding particles. It is shown that, within a finite time interval, which is independent of the total mass of the entire system, a giant particle of mass about the mass of the entire system may appear in this system. The particle in queear in this system. The particle in question is unobservable in the thermodynamic limit, and this explains the well-known paradox of mass-concentration nonconservation in classical kinetic theory. The theory described in the present article is successfully applied in studying the time evolution of random graphs.

Pobreza global o desigualdad doméstica: Una crítica a las propuestas de David Miller y Laura Valentini  

Scientific Electronic Library Online (English)

Full Text Available SciELO Colombia | Language: Spanish Abstract in spanish En este trabajo cuestiono las razones que ofrecen David Miller y Laura Valentini para afirmar que el deber de reducir la desigualdad dentro del propio Estado tiene prioridad sobre el deber de reducir la pobreza extrema global. Según Miller, los deberes globales, a diferencia de los domésticos, no pu [...] eden legítimamente hacerse cumplir mediante la fuerza, y por esa razón son meros deberes humanitarios que tienen menor peso que los deberes domésticos, que son deberes de justicia. Según Valentini, el deber de reducir la desigualdad doméstica tiene prioridad sobre los deberes humanitarios globales porque el primero es un deber de no dañar, mientras que los segundos son meros deberes de ayudar. El problema principal de ambas propuestas consiste en que fallan en su intento de mostrar que los deberes de reducir la pobreza extrema global no son también deberes de justicia. Abstract in english In this article I question David Miller and Laura Valentini's reasons to claim that duties to reduce inequalities inside the State should be prioritized over duties to reduce extreme global poverty. According to Miller, global duties, unlike domestic ones, cannot be legitimately enforced, and they a [...] re therefore mere humanitarian duties that weigh less than domestic duties, which are duties of justice. According to Valentini, domestic duties should be prioritized over global humanitarian duties because the former are duties not to harm, while the latter are mere duties to help. I argue that both views fail in their attempt to show that duties to reduce extreme global poverty are not duties ofjustice too.

Oriented bivariant theories, I  

CERN Document Server

In 1981 W. Fulton and R. MacPherson introduced the notion of bivariant theory (BT), which is a sophisticated unification of covariant theories and contravariant theories. This is for the study of singular spaces. In 2001 M. Levine and F. Morel introduced the notion of algebraic cobordism, which is a universal oriented Borel-Moore functor with products (OBMF) of geometric type, in an attempt to understand better V. Voevodsky's (higher) algebraic cobordism. In this paper we introduce a notion of oriented bivariant theory (OBT), a special case of which is nothing but the oriented Borel-Moore functor with products. The present paper is a first one of the series to try to understand Levine-Morel's algebraic cobordism from a bivariant-theoretical viewpoint, and its first step is to introduce OBT as a unification of BT and OBMF.

Nonlocality in string theory  

Science.gov (United States)

We discuss an aspect of string theory which has been tackled from many different perspectives, but incompletely: the role of nonlocality in the theory and its relation to the geometric shape of the string. In particular, we will describe in quantitative terms how one can zoom out from an extended object such as a string in such a way that, at sufficiently large scales, it appears structureless. Since there are no free parameters in free-string theory, the notion of large scales will be unambiguously determined. In other words, we will be able to answer the question: how and at which scale can the string be seen as a particle? In doing so, we will employ the concept of spectral dimension in a new way with respect to its usual applications in quantum gravity. The operational notions of worldsheet and target spacetime dimension in string theory are also clarified and found to be in mutual agreement.

Galaxy Formation Theory  

CERN Document Server

We review the current theory of how galaxies form within the cosmological framework provided by the cold dark matter paradigm for structure formation. Beginning with the pre-galactic evolution of baryonic material we describe the analytical and numerical understanding of how baryons condense into galaxies, what determines the structure of those galaxies and how internal and external processes (including star formation, merging, active galactic nuclei etc.) determine their gross properties and evolution. Throughout, we highlight successes and failings of current galaxy formation theory. We include a review of computational implementations of galaxy formation theory and assess their ability to provide reliable modeling of this complex phenomenon. We finish with a discussion of several "hot topics" in contemporary galaxy formation theory and assess future directions for this field.

Theory of polymer blends  

International Nuclear Information System (INIS)

We have recently developed a new theoretical approach to the study of polymer liquids. The theory is based on the ''reference interaction site model'' (RISM theory) of Chandler and Andersen, which has been successful in describing the structure of small molecule liquids. We have recently extended our polymer RISM theory to the case of polymer blends. In the present investigation we have applied this theory to two special binary blends: (1) the athermal mixture where we isolate structural effects, and (2) the isotopic mixture in which structurally identical polymer chains interact with dissimilar attractive interactions. By studying these two special cases we are able to obtain insights into the molecular factors which control the miscibility in polymer mixtures. 18 refs., 2 figs

Observables in Higgsed Theories  

CERN Document Server

In gauge theories, observable quantities have to be gauge-invariant. In general, this requires composite operators, which usually have substantially different properties, e.g. masses, than the elementary particles. Theories with a Higgs field, in which the Brout-Englert-Higgs effect is active, provide an interesting exception to this rule. Due to an intricate mechanism, the Fr\\"ohlich-Morchio-Strocchi mechanism, the masses of the composite operators with the same $J^P$ quantum numbers, but modified internal quantum numbers, have the same masses. This mechanism is supported using lattice gauge theory for the standard-model Higgs sector, i.e. Yang-Mills-Higgs theory with gauge group SU(2) and custodial symmetry group SU(2). Furthermore, the extension to the 2-Higgs-doublet-model is briefly discussed, and some preliminary results are presented.

Spectral rate theory  

CERN Document Server

Classical rate theories fail in cases where the observable(s) or order parameter(s) used are poor reaction coordinates and no clear separation between reactants and products is possible. Here, we present a general rate theory for ergodic dynamical systems in thermal equilibrium which allows the systematic estimation errors made by standard rate theories to be understood and quantified. We also elucidate the connection of spectral rate theory with the popular Markov state model- ing (MSM) approach for molecular simulation studies. An optimal rate estimator is formulated that gives robust and unbiased results even for poor reaction coordinates and can be applied to both computer simulations and single-molecule experiments. No definition of a dividing surface is required, and a measure of the reaction coordinate quality (RCQ) becomes readily available. Additionally, the respective projected probability distributions can be obtained for the reactant and product states along the observed order parameter, even when...

Extended quantum theory  

International Nuclear Information System (INIS)

It is shown in [2] that, besides the Heisenberg-Schrodinger quantum mechanics at moderate energies (MEQM), there exist else two quantum theories: high-energy quantum mechanics (HEQM) and low-energy one (LEQM) completed the first by natural way. In the latter, the well-known symmetry between the configuration and momentum spaces, inherent in MEQM, is broken. In this paper, the connection between these three theories is established (briefly, the complete theory is called EQ-theory). HEQM is well adapted to the description of particle constituents - granules. The connection of these objects playing the role of hidden entities with particles and their dynamical structure and physical properties is made clear. This dynamical structure breaks such laws of laboratory (Lagrangian) physics as the conservation of energy, fermionic charge, and probability. It causes also the P, C, T and fermion-antifermion asymmetry of our Universe

Wormholes in string theory  

Energy Technology Data Exchange (ETDEWEB)

We discuss the wormhole effective interactions in string theory, thought of as a sum over two-dimensional field theories on different world sheets. The effective interactions are calculated in the dilute wormhole approximation,'' initially by considering the Green's functions on higher-genus Riemann surfaces, and then by calculating the effect of a complete basis of wave functions on scattering amplitudes for a surface with a boundary. The sum over wormholes is equivalent to having a world sheet of trivial topology and summing over different space-time and matter-field backgrounds. To leading order these consist of the massless fluctuations, since the tachyon cancels out when a sum is done over different spin structures going through the wormhole. In this way we recover quantized general relativity as an effective theory, from a sum over field theories on higher-genus Riemann surfaces.

Algebraic number theory  

CERN Document Server

The technical difficulties of algebraic number theory often make this subject appear difficult to beginners. This undergraduate textbook provides a welcome solution to these problems as it provides an approachable and thorough introduction to the topic. Algebraic Number Theory takes the reader from unique factorisation in the integers through to the modern-day number field sieve. The first few chapters consider the importance of arithmetic in fields larger than the rational numbers. Whilst some results generalise well, the unique factorisation of the integers in these more general number fields often fail. Algebraic number theory aims to overcome this problem. Most examples are taken from quadratic fields, for which calculations are easy to perform. The middle section considers more general theory and results for number fields, and the book concludes with some topics which are more likely to be suitable for advanced students, namely, the analytic class number formula and the number field sieve. This is the fi...

Relativistic theories of materials  

CERN Document Server

The theory of relativity was created in 1905 to solve a problem concerning electromagnetic fields. That solution was reached by means of profound changes in fundamental concepts and ideas that considerably affected the whole of physics. Moreover, when Einstein took gravitation into account, he was forced to develop radical changes also in our space-time concepts (1916). Relativistic works on heat, thermodynamics, and elasticity appeared as early as 1911. However, general theories having a thermodynamic basis, including heat conduction and constitutive equations, did not appear in general relativity until about 1955 for fluids and appeared only after 1960 for elastic or more general finitely deformed materials. These theories dealt with materials with memory, and in this connection some relativistic versions of the principle of material indifference were considered. Even more recently, relativistic theories incorporating finite deformations for polarizable and magnetizable materials and those in which couple s...

Covariant Quiver Gauge Theories  

CERN Document Server

We consider dimensional reduction of gauge theories with arbitrary gauge group in a formalism based on equivariant principal bundles. For the classical gauge groups we clarify the relations between equivariant principal bundles and quiver bundles, and show that the reduced quiver gauge theories are all generically built on the same universal symmetry breaking pattern. The formalism enables the dimensional reduction of Chern-Simons gauge theories in arbitrary odd dimensionalities. The reduced model is a novel Chern-Simons-Higgs theory consisting of a Chern-Simons term valued in the residual gauge group plus a higher order gauge and diffeomorphism invariant coupling of Higgs fields with the gauge fields. We study the moduli spaces of solutions, which in some instances provide geometric representations of certain quiver varieties as moduli spaces of flat invariant connections. As physical applications, we consider dimensional reductions involving non-compact gauge supergroups as a means for systematically induci...

Compatible quantum theory.  

Science.gov (United States)

Formulations of quantum mechanics (QM) can be characterized as realistic, operationalist, or a combination of the two. In this paper a realistic theory is defined as describing a closed system entirely by means of entities and concepts pertaining to the system. An operationalist theory, on the other hand, requires in addition entities external to the system. A realistic formulation comprises an ontology, the set of (mathematical) entities that describe the system, and assertions, the set of correct statements (predictions) the theory makes about the objects in the ontology. Classical mechanics is the prime example of a realistic physical theory. A straightforward generalization of classical mechanics to QM is hampered by the inconsistency of quantum properties with classical logic, a circumstance that was noted many years ago by Birkhoff and von Neumann. The present realistic formulation of the histories approach originally introduced by Griffiths, which we call 'compatible quantum theory (CQT)', consists of a 'microscopic' part (MIQM), which applies to a closed quantum system of any size, and a 'macroscopic' part (MAQM), which requires the participation of a large (ideally, an infinite) system. The first (MIQM) can be fully formulated based solely on the assumption of a Hilbert space ontology and the noncontextuality of probability values, relying in an essential way on Gleason's theorem and on an application to dynamics due in large part to Nistico. Thus, the present formulation, in contrast to earlier ones, derives the Born probability formulas and the consistency (decoherence) conditions for frameworks. The microscopic theory does not, however, possess a unique corpus of assertions, but rather a multiplicity of contextual truths ('c-truths'), each one associated with a different framework. This circumstance leads us to consider the microscopic theory to be physically indeterminate and therefore incomplete, though logically coherent. The completion of the theory requires a macroscopic mechanism for selecting a physical framework, which is part of the macroscopic theory (MAQM). The selection of a physical framework involves the breaking of the microscopic 'framework symmetry', which can proceed either phenomenologically as in the standard quantum measurement theory, or more fundamentally by considering the quantum system under study to be a subsystem of a macroscopic quantum system. The decoherent histories formulation of Gell-Mann and Hartle, as well as that of Omnès, are theories of this fundamental type, where the physical framework is selected by a coarse-graining procedure in which the physical phenomenon of decoherence plays an essential role. Various well-known interpretations of QM are described from the perspective of CQT. Detailed definitions and proofs are presented in the appendices. PMID:25146940
