    2008-05-01

    Exercise intolerance and undue fatigue are common complaints in patients with Charcot-Marie-Tooth (CMT) disease. Reduced physical ability is due directly to the disease, but it is also due to physical deconditioning. The aim of this study was to test whether 24 weeks of interval-training exercise (ITE) cycling can significantly improve physiological, neuromuscular, and functional capacities and alleviate fatigue in CMT patients. Eight CMT patients (4 CMT1A and 4 CMT2) participated in ITE for 3 nonconsecutive days per week. Cardiovascular fitness, muscle strength, fatigue resistance, and functional capacities were measured before and after 12 weeks of supervised hospital training and again after another 12 weeks of unsupervised home training. Training was well tolerated. There were significant improvements in cardiorespiratory capacities, isokinetic concentric strength, and functional ability measurements. All patients experienced an improvement in their self-reported visual analogic scale for fatigue and pain during training. However, there was no significant change in their isometric force production and indices of fatigue resistance after training. Although the improvement in exercise tolerance may be due in part to reversal of the deconditioning effect of their related sedentary lifestyle, this clinical trial suggests that ITE can benefit CMT patients especially in their functional performance and subjective perception of pain and fatigue. Moreover, the improvement observed at the end of the first supervised period ITE was maintained after the second unsupervised home period, although there was no further improvement in performance and tolerance.

    Erna was one of the child patients treated by Melanie Klein in Berlin, employing her recently discovered play technique. Since Erna died in Chile, the authors considered the IPA Congress in Santiago an opportunity to present a paper as a homage both to Erna and, especially, to Klein. She learned much from that very disturbed child, which she later used to sustain the ongoing development of her theories. The paper explores biographic data relevant to understanding both the case and the theories. It analyses the case material to follow Klein in the discovery and the handling of the child's transference and the harsh expressions of hate, jealousy and envy, which are brought in, with sad consequences, by strong persecutory feelings. Klein's comparison of this case with that of Freud's Wolf-man is also considered, mostly to show that the similarities were less than originally claimed, and that Klein, perhaps, was introducing a theoretic shift which led her technique to gradually change from 'Nachträglichkeit' to the 'signification-resignification' pair, akin to Strachey's concept of the mutative interpretation. Lastly, the comprehension of Erna's strong psychotic traits and the links with later developments of the theory on psychosis are studied.

  16. Winnicott's response to Klein.

    2004-04-01

    The author suggests that, although Donald Winnicott presented some important criticisms of Melanie Klein's work, at times he tried to advance his perspectives too definitively without adequately considering her own. Because of this, he failed to acknowledge sufficiently that he was offering a model of human nature and development that could be revised. The fact that his differences with Klein arose in the context of a complex relationship in which each played numerous roles for the other, especially in the context of their affiliation with the British Psychoanalytical Society, periodically made it difficult for him to present his ideas more carefully and in his more characteristically open manner.

  18. Kaluza-Klein dark matter

    CERN Document Server

    Cheng, H C; Matchev, K T; Cheng, Hsin-Chia; Feng, Jonathan L; Matchev, Konstantin T.

    2002-01-01

    We propose that cold dark matter is made of Kaluza-Klein particles and explore avenues for its detection. The lightest Kaluza-Klein state is an excellent dark matter candidate if standard model particles propagate in extra dimensions and Kaluza-Klein parity is conserved. We consider Kaluza-Klein gauge bosons. In sharp contrast to the case of supersymmetric dark matter, these annihilate to hard positrons, neutrinos and photons with unsuppressed rates. Direct detection signals are also promising. These conclusions are generic to bosonic dark matter candidates.

  3. Obituary: Michael John Klein, 1940-2005

    Gulkis, Samuel

    2006-12-01

    Michael John Klein died on 14 May 2005 at home in South Pasadena, California. The cause of death was tongue cancer that metastasized to the lungs. He was a non-smoker. Mike was a passionate radio astronomer, a trusted astronomical observer, an educator and a family man. Mike was born on 19 January 1940 in Ames, Iowa, the son of Florence Marie (Graf) and Fred Michael Klein. His mother was a homemaker, and his father was a banker. Mike had two older sisters, Lois Jean (Klein) Flauher and Marilyn June (Klein) Griffin. In 1962, Mike married his high school sweetheart Barbara Dahlberg, who survives him along with their three children, Kristin Marie (Klein) Shields, Michael John Klein Jr., Timothy Joel Klein, and six grandchildren. Mike developed a love for astronomy early in his life, and credited an early morning, newspaper-delivery route that he had at age twelve, which took him outside well before sunrise. He told family members that as he walked along his route, he stared into the sky and wondered what everything was. He studied sky charts, located stars, and began to understand how the planets shifted their positions relative to the stars each day. Another big influence in Mike's life was his brother in-law, Jim Griffin. Jim helped Mike understand that his passion for science did not have to remain a hobby, but could and should become a career. Jim's encouragement led Mike to attend Iowa State University in Ames, where he earned a BS in electrical engineering in 1962. Mike then started graduate school in electrical engineering at Michigan State, but after one semester transferred to the University of Michigan, Ann Arbor, where he earned an MS (1966) and PhD (1968) in astronomy. His doctoral dissertation, under the direction of Professor Fred Haddock, was based on extensive observations of the planets and examined the physical and thermal properties of planetary atmospheres and surfaces. Mike was awarded a Resident Research Associate position at JPL by the National

  6. On Kaluza-Klein theory

    International Nuclear Information System (INIS)

    Salam, A.; Strathdee, J.

    1981-10-01

    Assuming the compactification of 4+K-dimensional spacetime 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 0(1,2). (author)

  7. Instability of the Kaluza-Klein vacuum

    International Nuclear Information System (INIS)

    Witten, E.

    1982-01-01

    It is argued that the ground state of the Kaluza-Klein unified theory is unstable against a process of semiclassical barrier penetration. This is related to the fact that the positive energy conjecture does not hold for the Kaluza-Klein theory; an explicit counter-example is given. The reasoning presented here assumes that in general relativity one should include manifolds of non-vacuum topology. It is argued that the existence of elementary fermions (not present in the original Kaluza-Klein theory) would stabilize the Kaluza-Klein vacuum. (orig.)

This article reviews the current available research and describes common clinical symptoms, differential diagnosis, and acceptable workup and treatment. Although deficits have traditionally been thought to resolve between episodes, functional imaging studies and long-term neuropsychological testing in select patients have recently challenged this notion. This may suggest that Kleine-Levin syndrome is not as benign as previously considered. Keywords: Kleine-Levin syndrome, hypersomnia, adolescent sleep disorder, hypersexuality

  14. Stability of squashed Kaluza-Klein black holes

    International Nuclear Information System (INIS)

    Kimura, Masashi; Ishihara, Hideki; Murata, Keiju; Soda, Jiro

    2008-01-01

    The stability of squashed Kaluza-Klein black holes is studied. The squashed Kaluza-Klein black hole looks like a five-dimensional black hole in the vicinity of horizon and looks like a four-dimensional Minkowski spacetime with a circle at infinity. In this sense, squashed Kaluza-Klein black holes can be regarded as black holes in the Kaluza-Klein spacetimes. Using the symmetry of squashed Kaluza-Klein black holes, SU(2)xU(1)≅U(2), we obtain master equations for a part of the metric perturbations relevant to the stability. The analysis based on the master equations gives strong evidence for the stability of squashed Kaluza-Klein black holes. Hence, the squashed Kaluza-Klein black holes deserve to be taken seriously as realistic black holes in the Kaluza-Klein spacetime.

    Science.gov (United States)

    Hashemi, S. Sedigheh; Riazi, Nematollah

    2018-02-01

    In this work, we consider a vacuum solution of Kaluza-Klein theory with cylindrical symmetry. We investigate the physical properties of the solution as viewed in four dimensional spacetime, which turns out to be a stationary, cylindrical wormhole supported by a scalar field and a magnetic field oriented along the wormhole. We then apply a boost to the five dimensional solution along the extra dimension, and perform the Kaluza-Klein reduction. As a result, we show that the new solution is still a wormhole with a radial electric field and a magnetic field stretched along the wormhole throat.

  18. Melanie Klein's metapsychology: phenomenological and mechanistic perspective.

    Science.gov (United States)

    Mackay, N

    1981-01-01

    Freud's metapsychology is the subject of an important debate. This is over whether psychoanalysis is best construed as a science of the natural science type or as a special human science. The same debate applies to Melanie Klein's work. In Klein's metapsychology are two different and incompatible models of explanation. One is taken over from Freud's structural theory and appears to be similarly mechanistic. The other is clinically based and phenomenological. These two are discussed with special reference to the concepts of "phantasy" and "internal object".

    This paper connects the work of Melanie Klein on mourning to the pastor's work with the grief sufferer. Klein holds that mourning is an illness of manic depressive character rooted in infantile development. Klein's description of manic defenses in the face of loss has adult behavioral analogues with which the pastor must deal to bring mourning to resolution.

  12. Marie Curie: scientific entrepreneur

    Energy Technology Data Exchange (ETDEWEB)

    Boudia, S. [Curie Muesum, Paris (France)

    1998-12-01

    Marie Curie is best known for her discovery of radium one hundred years ago this month, but she also worked closely with industry in developing methods to make and monitor radioactive material, as Soraya Boudia explains. One hundred years ago this month, on 28 December 1898, Pierre Curie, Marie Sklodowska-Curie and Gustave Bemont published a paper in Comptes-rendus - the journal of the French Academy of Sciences. In the paper they announced that they had discovered a new element with astonishing properties: radium. But for one of the authors, Marie Curie, the paper was more than just the result of outstanding work: it showed that a woman could succeed in what was then very much a male-dominated scientific world. Having arrived in Paris from Poland in 1891, Marie Curie became the first woman in France to obtain a PhD in physics, the first woman to win a Nobel prize and the first woman to teach at the Sorbonne. She also helped to found a new scientific discipline: the study of radioactivity. She became an icon and a role-model for other women to follow, someone who succeeded - despite many difficulties - in imposing herself on the world of science. Although Curie's life story is a familiar and well documented one, there is one side to her that is less well known: her interaction with industry. As well as training many nuclear physicists and radiochemists in her laboratory, she also became a scientific pioneer in industrial collaboration. In this article the author describes this side of Marie Curie. (UK)

    Harmark, Troels; Obers, N. A.

    2005-01-01

    We review the latest progress in understanding the phase structure of static and neutral Kaluza-Klein black holes, i.e. static and neutral solutions of pure gravity with an event horizon that asymptote to a d-dimensional Minkowski-space times a circle. We start by reviewing the (mu,n) phase diagram...... and the split-up of the phase structure into solutions with an internal SO(d-1) symmetry and solutions with Kaluza-Klein bubbles. We then discuss the uniform black string, non-uniform black string and localized black hole phases, and how those three phases are connected, involving issues such as classical...... instability and horizon-topology changing transitions. Finally, we review the bubble-black hole sequences, their place in the phase structure and interesting aspects such as the continuously infinite non-uniqueness of solutions for a given mass and relative tension....

    The field equations of Kaluza—Klein (KK) theory have been applied in the domain of cosmology. These equations are solved for a flat universe by taking the gravitational and the cosmological constants as a function of time t. We use Taylor's expansion of cosmological function, Λ(t), up to the first order of the time t. The cosmological parameters are calculated and some cosmological problems are discussed.

  16. Geometrical aspects of Kaluza-Klein theory

    International Nuclear Information System (INIS)

    Maia, M.D.

    1983-08-01

    The standard approaches to Kaluza-Klein theory assume the existence of a high dimensional space, from which the four-dimensional space-time would be recovered by a dimensional reduction procedure. In the present note the four-dimensional space-time is regarded as a hypersurface locally embedded in the ever-present (4+n)-dimensional space. In the simplest case where the high dimensional space is taken to be flat, the Kaluza-Klein metric is derived from the embedding assumption. However, this metric is invertible only if the range of the extra n coordinates is limited to an n - dimensional sphere with radius proportional to the local curvature radius of the space-time. Almost independently of this compactification the dimensional reduction, here described in terms of ''complete confinement'', is achieved by a symmetry breaking leading to P 4 x G and which is triggered by the limit of vanishing gravitation. The dynamics for an observer confined to the four-dimensional space-time is described by the embedding integrability conditions. On the other hand for a non-confined observer a unifying picture close to the Kaluza-Klein objectives is obtained. Finally a brief analysis of fermions and fermion masses is also included. (author)

  17. Kleine-Levin syndrome ethiopathogenesis and treatment.

    Science.gov (United States)

    Smolík, P; Roth, B

    1988-01-01

    The complex of the symptoms of psychic disorders and of the disorders of sleep, appetite, and food intake often forms the basis of the clinical picture of a mental disease. However, it is only rarely conceived in a complex manner as a set of physiologically interdependent functions. A remarkable proof of the interdependence of these functions is their complex disorder, the Kleine-Levin syndrome. The first descriptions of the symptoms of the Kleine-Levin syndrome can be found in the studies of several authors published as early as at the turn of the century. In 1942, the syndrome was designated by Critchley and Hoffmann after Willi Kleine and Max Levin, who defined it precisely in 1925 and 1929. The syndrome of periodic hypersomnia, megaphagia, and psychic disorders, originally described only in young males, was later found in females as well; the original very strict criteria were gradually broadened and complemented to some extent. At present, the most commonly accepted criterion for the diagnosis of the Kleine-Levin syndrome is the existence of the combined sleep disorder (hypersomnia or insomnia lasting from days to weeks), food intake disorders (megaphagia or anorexia), and various psychic abnormalities accompanying or following the attacks of the affection. We term the syndrome typical if the sleep disorder appears in the form of hypersomnia, food disorder in the form of megaphagia, and if psychic abnormalities are clearly expressed. On the other hand, we term the syndrome atypical if one of the main symptoms is opposite. The incomplete syndrome consists of only two main symptoms. The attacks of the affection set on mostly suddenly, lasting from several days to several weeks, ending suddenly again. The interparoxysmal periods last from several days to several months, sometimes even to several years. The etiopathogenesis of the affection is still unknown. A number of reports indicate a disorder of the diencephalon, perhaps only of the hypothalamus. The

    We study the Klein-Gordon oscillators in non-commutative (NC) phase space. We find that the Klein-Gordon oscillators in NC space and NC phase-space have a similar behaviour to the dynamics of a particle in commutative space moving in a uniform magnetic field. By solving the Klein-Gordon equation in NC phase space, we obtain the energy levels of the Klein-Gordon oscillators, where the additional terms related to the space-space and momentum-momentum non-commutativity are given explicitly.

    Using suitable adaptions of the calculus of exterior forms, we point out that the derivation of the Einstein/Yang-Mills Lagrangian with a (formal) cosmological term from the (Riemannian) scalar curvature density of a G-bundle space can be performed almost by inspection. This method also provides a simple explanation of this so-called 'Kaluza/Klein miracle'. The equivalence of the corresponding bundle field equations with the Einstein/Yang-Mills equations over the base is shown (i.e. there is no need for an 'integration over the group degrees of freedom'). The inclusion of matter fields is discussed briefly. (Author)

    Why does Mary hold her prominent place in Catholic theology to the extent that five specific dogmas have developed around her? Psychoanalytic theory suggests dogma arises out of the psychic needs of people and psychic needs of people are expressed in dogma. The early views of Erich Fromm, a disciple of Freud, are presented to demonstrate that Marian dogma arose from the psychic needs of the people. The views of both Catholic and Protestant thinkers are presented, as well as theological and psychiatric views.

    In this paper we present explicit formulas for the fundamental solution to the Klein-Gordon operator on some higher dimensional generalizations of the Möbius strip and the Klein bottle with values in distinct pinor bundles. The fundamental solution is described in terms of generalizations of the Weierstrass ℘ -function that are adapted to the context of these geometries. The explicit formulas for the kernel then allow us to express all solutions to the homogeneous and inhomogeneous Klein-Gordon problem with given boundary data in the context of these manifolds. In the case of the Klein bottle we are able to describe all null solutions of the Klein-Gordon equation in terms of finite linear combinations of the fundamental solution and its partial derivatives

    2016-03-01

    Compared to the impact of the work of Melanie Klein on the history of psychoanalysis, the contributions of her daughter, Melitta Schmideberg, passed almost unnoticed. At present, Schmideberg is solely remembered for having harshly attacked her mother at the start of the Controversial Discussions of the British Psycho-Analytical Society and for having coined the fitting expression "stable instability" in order to describe borderline and asocial personality disorders. However, the author discusses how the early groundbreaking discoveries of Klein with regards to primitive anxieties were the result of the joint work and thinking of Melanie and Melitta. Moreover, he argues that the conflict between the two, along with the subsequent polarization of their views, did not facilitate the development of psychoanalysis, neither did it help the analytic community to recognize the value of Melitta's contributions to psychoanalysis.

    In 1919 Th. Kaluza made a remarkable observation. If one considers Einstein's theory in 5 dimensions and calculates with the ansatz g = gsup(μν) dxsub(μ) dxsub(ν) + (dx 5 + Asup(μ)dxsub(μ)) 2 , μ = 1,...4 (1.1), and gsup(μν)sub(,5) = Asup(μ)sub(,5) = 0 the curvature scalar Rsup((5)) in 5 dimensions one finds Rsup((5)) = Rsup((4)) - 1/4 x (Asub(μ,ν) - Asub(ν,μ)) x (Asup(μ,ν) - Asup(ν,μ)). Thus this Lagrangian reproduces exactly the coupled Einstein-Maxwell equations. A realistic interpretation of the ansatz (1.1) is nowadays thinkable. Restricting to pure gravity the physics of 4+D-dimensional Einstein spaces with a structure given by (1.1) is considered. Finally a Kaluza-Klein cosmology is outlined. (G.Q.)

By using a generic communication framework, MARIE aims to create a flexible distributed component system that allows robotics developers to share software programs and algorithms, and design prototypes rapidly based on their own integration needs. The use of MARIE is illustrated with the design of a socially interactive autonomous mobile robot platform capable of map building, localization, navigation, tasks scheduling, sound source localization, tracking and separation, speech recognition and generation, visual tracking, message reading and graphical interaction using a touch screen interface.

  13. [An unpublished contribution of Melanie Klein "On Reassurance"].

    2005-01-01

    Melanie Klein's unpublished paper on reassurance is presented in German translation. The author shows that it was a contribution to Glover's investigation on psychoanalytic technique in the 1930s. The paper is discussed against the background of the technical discussions conducted in London at that time (e. g. M. Schmideberg, J. Strachey) and of Klein's relevant publications. Although Klein consistently considered "correct" interpretation to be the most effective means of reassurance, she occasionally also accepted a non-interpreting approach. In this respect the paper presented here goes further than any other of her writings.

  14. Melanie Klein and countertransference: a note on some archival material.

    2008-01-01

    Five pages of notes were found in the Melanie Klein Archives at the Wellcome Library that concern her views on countertransference in 1953. Because of the paucity of references to countertransference in Klein's published writings these Notes fill in out knowledge. Her views were provoked by the work her students were doing in their experimental analyses of schizophrenic patients. Apocryphal stories suggest that Klein remained aligned with Freud's view of countertransference as simply interference. The Notes confirm that, whilst there is some truth to that, she did have a more sophisticated and nuanced view of the unconscious relations between analyst and analysand.

  15. The conflict and process theory of Melanie Klein.

    Science.gov (United States)

    Kavaler-Adler, S

    1993-09-01

    This article depicts the theory of Melanie Klein in both its conflict and process dimensions. In addition, it outlines Klein's strategic place in psychoanalytic history and in psychoanalytic theory formation. Her major contributions are seen in light of their clinical imperatives, and aspects of her metapsychology that seem negligible are differentiated from these clinical imperatives. Klein's role as a dialectical fulcrum between drive and object relations theories is explicated. Within the conflict theory, drive derivatives of sex and aggression are reformulated as object-related passions of love and hate. The process dimensions of Klein's theory are outlined in terms of dialectical increments of depressive position process as it alternates with regressive paranoid-schizoid-position mental phenomenology. The mourning process as a developmental process is particularly high-lighted in terms of self-integrative progression within the working through of the depressive position.

    The coupled nonlinear Klein-Gordon equations are analyzed for their integrability properties in a systematic manner through Painleve test. From the Painleve test, by truncating the Laurent series at the constant level term, the Hirota bilinear form is identified, from which one-soliton solutions are derived. Then, the results are generalized to the two, three and N-coupled Klein-Gordon equations

  17. Primitive object love in Melanie Klein's thinking; early theoretical influences.

    Science.gov (United States)

    Likierman, M

    1993-04-01

    Melanie Klein's thinking on early object love is pivotal to her vision of development. Yet within her texts it is often enmeshed in complex formulations that obscure its full significance. A greater clarity in viewing Klein's concept of early object love is achieved through tracing some of its historical origins. The author notes that it was inspired by aspects of Ferenczi's theory, hence its similarities with the concept of 'primary love' formulated by another of Ferenczi's analysands, Michael Balint. Ferenczi's thinking on the subject formed part of a broader network of theoretical developments in the history of psychoanalytic ideas. These are shown to have origins in Freud's fluctuations between a 'passive' and a 'genital' characterisation of infantile sexuality. A dialectical tension between these two possibilities, as maintained in the Freudian texts, was partly embodied in the differing outlooks of Klein's two psychoanalysts, Abraham and Ferenczi. The author suggests that it is a mixture of their approaches that partly shaped Klein's thinking on the earliest experiences of love. After outlining these developments the author analyses the nature of early object love as it emerges from Klein's powerful, if intermittent descriptions in the texts. The analysis also tackles a textual ambiguity in Klein's formulations, showing that she explored two kinds of primitive ideal experience without explicitly differentiating them. Such differentiation is important inasmuch as it highlights negative and positive aspects of Kleinian theory at root.

  1. Marie Curie: Physicist and Woman

    Science.gov (United States)

    Howes, Ruth

    Marie Sklodowska was born in Warsaw on November 7, 1867. Girls were not allowed to attend college in Poland, so Marie found a well-paying post as a governess in rural village which she held for three years while helping her older sister complete medical school in Paris. Then Marie moved to Paris and graduated first in her class at the Sorbonne with a master's degree in physics in 1893. In 1895, she married the talented young physicist, Pierre Curie. Marie decided to investigate the radioactive components of the mineral pitchblende for her dissertation. The work involved chemical analysis of a ton of material in an unheated shed. Pierre joined her and at the end of 1898, the Curies announced the discovery of radium and polonium. Through 1899, Marie labored to measure the atomic weight of radium. In 1903, Marie earned her doctorate, the first for a woman in France, and the Curies split the Nobel Prize in Physics with Henri Becquerel. They became widely known, besieged by the press and frequently invited to make presentations and be awarded honors. They hated fame and both suffered bad health. In April, 1906, Pierre Curie was struck by a wagon and killed instantly. Marie was left as a single mother with two young daughters. Fortunately, the Sorbonne hired her to fill Pierre's position. In 1911, she was rejected for membership in the French Academy of Science because she was a woman. Also in 1911, she was accused of having an affair with a married French physicist Paul Langevin. The resulting scandal hit the press and brought angry mobs to her home. In the middle of this hullaballoo, she was informed that she had won a second Nobel Prize, this time in Chemistry. When World War I broke out, Marie mounted x-ray units on cars and became a heroine. She visited the United States in 1921 where President Harding presented her with a gram of radium. She continued her scientific studies in spite of declining health until her death in 1934. Professor Emerita.

  2. Melanie Klein's letters addressed to Marcelle Spira (1955-1960).

    2009-12-01

    Between 1955 and 1960, Melanie Klein wrote some 45 hitherto unpublished letters to Marcelle Spira, the Swiss psychoanalyst living at that time in Geneva. In 2006, after Spira's death, these letters were deposited with the Raymond de Saussure Psychoanalysis Centre in Geneva. They are the only known letters that Klein addressed to her psychoanalyst colleagues. Several topics are mentioned in them: (1) the meetings between the two women in Geneva and London; (2) Spira's contribution to Boulanger's translation into French of The Psychoanalysis of Children, which Klein herself carefully revised; (3) the papers that Klein was at that time working on, including Envy and Gratitude; (4) Spira's own work; (5) the difficulties that Spira, a Kleinian psychoanalyst who trained in Buenos Aires, was encountering in her attempt to be admitted to the Swiss Psychoanalytical Society; and (6) a few items of personal and family news. In addition to the invaluable historical information that these letters provide, they offer us a very moving epistolary self-portrait of Melanie Klein, enabling us to discover her personality in the final years of her life - she died in September 1960, just two months after writing her last letter to Spira.

  4. Boosted black holes on Kaluza-Klein bubbles

    International Nuclear Information System (INIS)

    Iguchi, Hideo; Mishima, Takashi; Tomizawa, Shinya

    2007-01-01

    We construct an exact stationary solution of black-hole-bubble sequence in the five-dimensional Kaluza-Klein theory by using solitonic solution-generating techniques. The solution describes two stationary black holes with topology S 3 on a Kaluza-Klein bubble and has a linear momentum component in the compactified direction. We call the solution boosted black holes on Kaluza-Klein bubble because it has the linear momentum. The Arnowitt-Deser-Misner mass and the linear momentum depend on the two boosted velocity parameters of black holes. In the effective four-dimensional theory, the solution has an electric charge which is proportional to the linear momentum. The solution includes the static solution found by Elvang and Horowitz. The small and the big black holes limits are investigated. The relation between the solution and the single boosted black string are considered

  5. Neo-intuitive proposal for Kaluza-Klein unification

    International Nuclear Information System (INIS)

    Rosen, S.M.

    1988-01-01

    This paper addresses a central question of contemporary theoretical physics: Can a unified account be provided for the known forces of nature? The issue is brought into focus by considering the recently revived Kaluza-Klein approach to unification, a program entailing dimensional transformation through cosmogony. First it is demonstrated that, in a certain sense, revitalized Kaluza-Klein theory appears to undermine the intuitive foundations of mathematical physics, but that this implicit consequence has been repressed at a substantial cost. A fundamental reformation of the Kaluza-Klein strategy is then undertaken, one that casts it within a new intuitive context. This is followed by a provisional application of the suggested approach to the specific problem of cosmological change. The paper concludes by exploring the far-reaching epistemological implications of the neo-intuitive proposal set forth

  6. A new look at the theory of Melanie Klein.

    Science.gov (United States)

    Stein, R

    1990-01-01

    This paper tried to show that Melanie Klein's theory can very profitably be viewed as a descriptive theory of strong emotions rather than an instinct or developmental theory. Furthermore, since in Klein's thinking feelings 'create' objects, the primacy of feelings in this theory is central. The paper contains a short chronological study of Klein's formulations of psychic phenomena in terms of affects. It is also maintained that the paranoid-schizoid and the depressive positions are constellations of affects and of reactions to them; that psychic development is essentially in terms of the capacity to tolerate feelings, and that the basic conflict in mental life is between feelings of love and hate and associated feelings. Such a view solves many of the conceptual difficulties of Kleinian theory and in addition promises rewarding insights into the world of feelings.

Klein’s contributions on affect are discussed and confronted with the other elements of the psychological world: representations, drives, objects and positions. The second part of the paper presents and discusses Bion’s theory of “emotional experiences”, in which a primordial identity between thought and feelings generates every form of knowledge.

    The massless Klein-Gordon equation on arbitrary curved backgrounds allows for solutions which develop ''tails'' inside the light cone and, therefore, do not strictly follow null geodesics as discovered by DeWitt and Brehme almost 60 years ago. A modification of the massless Klein-Gordon equation is presented, which always exhibits null geodesic propagation of waves on arbitrary curved spacetimes. This new equation is derived from a Lagrangian which exhibits current-current interaction. Its non-linearity is due to a self-coupling term which is related to the quantum mechanical Bohm potential.

    Full Text Available Abstract Background Kleine-Levin syndrome is a rare sleep disorder of unknown etiology. It is characterized by intermittent periods of excessive sleepiness, cognitive disturbances and behavioral abnormalities. Nine cases of familial Kleine-Levin syndrome have been identified, but there are no reported cases describing twins that are affected by the syndrome. Case presentation We report the cases of 16-year-old monozygotic twin boys who both suffered from Kleine-Levin syndrome. In both cases, the onset of the first episode was preceded by an influenza infection. During symptomatic periods they slept for the entire day except for meals and bathroom visits. Actimetry recordings revealed that during symptomatic periods, daily activity was lower than that of asymptomatic periods, on the other hand, activity during the night was significantly higher in symptomatic periods than asymptomatic periods. Polysomnography (PSG data during symptomatic periods revealed a decrease in sleep efficiency. Human leukocyte antigen (HLA typing revealed no DQB1*02 loci. They were administered lithium carbonate but the beneficial effect was limited. Conclusions Our observations suggest that Kleine-Levin syndrome may be due to genetic and autoimmune processes, although etiologic relationship to specific HLA type remains controversial.

    We consider the applications of quasi-Riemannian geometry in Kaluza-Klein theories. We find that such theories cannot be implemented for all choices of the tangent group G/sub T/ and internal space G/H for reasons of gauge invariance. Coupling of fermions to gravity poses further problems in these theories

  2. Massive Kaluza-Klein theories and their spontaneously broken symmetries

    Energy Technology Data Exchange (ETDEWEB)

    Hohm, O.

    2006-07-15

    In this thesis we investigate the effective actions for massive Kaluza-Klein states, focusing on the massive modes of spin-3/2 and spin-2 fields. To this end we determine the spontaneously broken gauge symmetries associated to these 'higher-spin' states and construct the unbroken phase of the Kaluza-Klein theory. We show that for the particular background AdS{sub 3} x S{sup 3} x S{sup 3} a consistent coupling of the first massive spin-3/2 multiplet requires an enhancement of local supersymmetry, which in turn will be partially broken in the Kaluza-Klein vacuum. The corresponding action is constructed as a gauged maximal supergravity in D=3. Subsequently, the symmetries underlying an infinite tower of massive spin-2 states are analyzed in case of a Kaluza-Klein compactification of four-dimensional gravity to D=3. It is shown that the resulting gravity-spin-2 theory is given by a Chern-Simons action of an affine algebra and also allows a geometrical interpretation in terms of 'algebra-valued' differential geometry. The global symmetry group is determined, which contains an affine extension of the Ehlers group. We show that the broken phase can in turn be constructed via gauging a certain subgroup of the global symmetry group. Finally, deformations of the Kaluza-Klein theory on AdS{sub 3} x S{sup 3} x S{sup 3} and the corresponding symmetry breakings are analyzed as possible applications for the AdS/CFT correspondence.

    Charcot-Marie-Tooth (CMT) disease is the commonest inherited neuromuscular disorder affecting at least 1 in 2,500. Over the last two decades, there have been rapid advances in understanding the molecular basis for many forms of CMT with more than 30 causative genes now described. This has made obtaining an accurate genetic diagnosis possible but at times challenging for clinicians. This review aims to provide a simple, pragmatic approach to diagnosing CMT from a clinician\\'s perspective.

    Science.gov (United States)

    Aguayo, Joseph

    2002-10-01

    The author investigates the clinical affinity between Klein and Winnicott (1935-46) asa way to historically situate Winnicott 's later criticism of Klein's 'temperamental' inability to understand the impact of the environment on the infant's development. By setting out Klein s theories at the time when Winnicott began supervision with her in 1935, a context is established for the analysis of an unpublished 1937 manuscript by Klein ('Notes on baby'). The author argues that this direct and extensive infant observation demonstrates Klein's sensitivity to the familial environment. While Winnicott as a paediatrician showed enthusiasm for Klein s ideas, he also demonstrated a difference of opinion in emphasising the maternal environment of provision after his wartime evacuation experiences with London children. The factors leading to their mutual distancing are outlined as follows: (1) the post-Controversial Discussion atmosphere of the British Psycho-Analytical Society in 1944. The new non-aligned psychoanalytic 'middle group' allowed Winnicott to take a pick and choose attitude towards available analytic theories; (2) Winnicott us new clinical practices and theory differed from Klein 's, leading to a widening gap between 1946 and 1951. Winnicott's new theory and practice simultaneously represented his technical marginalisation of Klein s emphasis on the direct analysis of the patient s destructiveness by the time he delivered the 'Transitional objects' paper in 1951.

  7. Dimers on two types of lattices on the Klein bottle

    The problem of enumerating close-packed dimers, or perfect matchings, on two types of lattices (the so-called 8.8.4 and 8.8.6 lattices) embedded on the Klein bottle is considered, and we obtain the explicit expression of the number of close-packed dimers and entropy. Our results imply that 8.8.4 lattices have the same entropy under three different boundary conditions (cylindrical, toroidal and Klein bottle) and 8.8.6 lattices have the same property. This article is part of ‘Lattice models and integrability’, a special issue of Journal of Physics A: Mathematical and Theoretical in honour of F Y Wu's 80th birthday.

    A mathematically rigorous analysis of the Klein paradox is given in the many-particle formulation of the Dirac theory. This paradox was meant as an example demonstrating the negative energy problems of the single particle Dirac equation. However, it is shown that this problem does not disappear in the second quantized version of the Dirac theory. It corresponds with a situation which cannot be described properly within the framework of a field theory with an external potential. (AIP)

    A consistency problem for the Kaluza-Klein ansatz is shown to arise when the kinetic term of extra gauge fields depends on the internal coordinates. Consequences on cosmological solutions are discussed. A position-dependent kinetic term implies either a very special condition to be satisfied by it, or the time-independent size of internal space and the maximally symmetric universe in the vacuum.

    Cosmic superstrings interact generically with a tower of light and/or strongly coupled Kaluza-Klein (KK) modes associated with the geometry of the internal space. We study the production of KK particles by cosmic superstring loops, and show that it is constrained by big bang nucleosynthesis. We study the resulting constraints in the parameter space of the underlying string theory model and highlight their complementarity with the regions that can be probed by current and upcoming gravitational wave experiments.

  15. Reduced thalamic and pontine connectivity in Kleine-Levin syndrome

    Directory of Open Access Journals (Sweden)

    Maria eEngström

    2014-04-01

    Full Text Available The Kleine-Levin syndrome is a rare sleep disorder, characterized by exceptionally long sleep episodes. The neuropathology of the syndrome is unknown and treatment is often inadequate. The aim of the study was to improve understanding of the underlying neuropathology, related to cerebral networks, in Kleine-Levin syndrome during sleep episodes. One patient with Kleine-Levin syndrome and congenital nystagmus, was investigated by resting state functional Magnetic Resonance Imaging during both asymptomatic and hypersomnic periods. Fourteen healthy subjects were also investigated as control samples. Functional connectivity was assessed from seed regions of interest in the thalamus and the dorsal pons. Thalamic connectivity was normal in the asymptomatic patient whereas the connectivity between the brain stem, including dorsal pons, and the thalamus was diminished during hypersomnia. These results suggest that the patient’s nystagmus and hypersomnia might have their pathological origin in adjacent dorsal pontine regions. This finding provides additional knowledge of the cerebral networks involved in the neuropathology of this disabling disorder. Furthermore, these findings regarding a rare syndrome have broad implications and results could be of interest to researchers and clinicians in the whole field of sleep medicine.

  16. Gauged diffeomorphisms and hidden symmetries in Kaluza-Klein theories

    Energy Technology Data Exchange (ETDEWEB)

    Hohm, Olaf [Spinoza Institute and Institute for Theoretical Physics, Leuvenlaan 4, 3584 CE Utrecht (Netherlands)

    2007-06-07

    We analyse the symmetries that are realized on the massive Kaluza-Klein modes in generic D-dimensional backgrounds with three non-compact directions. For this, we construct the unbroken phase given by the decompactification limit, in which the higher Kaluza-Klein modes are massless. The latter admits an infinite-dimensional extension of the three-dimensional diffeomorphism group as local symmetry and, moreover, a current algebra associated with SL(D-2,R) together with the diffeomorphism algebra of the internal manifold as global symmetries. It is shown that the 'broken phase' can be reconstructed by gauging a certain subgroup of the global symmetries. This deforms the three-dimensional diffeomorphisms to a gauged version, and it is shown that they can be governed by a Chern-Simons theory, which unifies the spin-2 modes with the Kaluza-Klein vectors. This provides a reformulation of D-dimensional Einstein gravity, in which the physical degrees of freedom are described by the scalars of a gauged nonlinear {sigma}-model based on SL(D-2,R)/SO(D-2), while the metric appears in a purely topological Chern-Simons form.

    A discussion of recently discovered literature that reveals how after the Crimean War ended in 1856, Jamaican nurse, doctress and entrepreneur Mary Seacole travelled more widely and gained further international recognition than had previously been appreciated. New findings demonstrate that Seacole's international charitable and business activities were reported more widely than realised. Recently discovered literature uncovers her networking and strategic skills in various social milieus. A former Scutari nurse and 39 other women, offered their service to Seacole to nurse British soldiers in India. Newspapers also reported the medal she had been awarded from the Turkish government. Discussion paper. Digitized 19th-century newspaper reports, and 1857 Dutch and 1858 French translations of Seacole's autobiography and a recently discovered handwritten letter dated 1 October 1857 from Seacole to Sir Henry Storks, at the time Secretary for Military Correspondence at the War Office, London. Awareness of the findings affords a more thorough understanding of the scope and diversity of nursing history. This can provide valuable role models for the 21st century generations of competent and self-confident healthcare professionals. The new evidence offers further testimony that Seacole can truly be considered as one such figurehead. British and international primary sources reveal Mary Seacole as an historical and charismatic global phenomenon, more than had been previously realised. © 2014 John Wiley & Sons Ltd.

    We study the bound states of the Kaluza-Klein (KK) excitations of quarks in certain models of universal extra dimensions. Such bound states may be detected at future lepton colliders in the cross section for the pair production of KK quarks near threshold. For typical values of model parameters, we find that 'KK quarkonia' have widths in the 10-100 MeV range, and production cross sections of the order of a few picobarns for the lightest resonances. Two body decays of the constituent KK quarks lead to distinctive experimental signatures. We point out that such KK resonances may be discovered before any of the higher KK modes

    Simultaneous quantization of the quasi-simple groups of motions of the nine two-dimensional Cayley-Klein geometries is obtained by defining a deformed Hopf structure on their enveloping algebras. The spaces of points and lines of the classical CK geometries are homogeneous spaces of their motion groups. Both the well known classical non-euclidean geometries and the (1+1) kinematical geometries are included within this scheme. Their corresponding quantum algebras preserve a scheme of contractions, symmetries and dualities based on the classical one. (Author)

  9. Cosmological equations in Kaluza-Klein d=11 supergravity theory

    International Nuclear Information System (INIS)

    1984-01-01

    In d = 11 Kaluza-Klein theory having a component of the three-form potential A living on the seven-dimensional internal space, conditions on that internal component of A, so that cosmological equations of the Robertson-Walker type may be formulated, are given. In the equations the Ricci tensor is in general non-isotropic in the internal space. The specific examples of the squashed seven-sphere and a particular p, q, r coset manifold are given; in the latter case there is a static solution with non-Einstein internal space. (orig.)

    1983-12-01

    The aim of these lectures was to present a review of the ''multidimensional universes'' where the old Kaluza-Klein idea holds true. I give first a survey of the theory of fiber bundles. Then there is a discussion on invariant metrics on groups and homogeneous spaces. Then comes a very short section on basic Riemannian geometry. The important results about the structure (topology and metric) of these multidimensional universes is given, the physical ideas are also discussed. In section 6 we show how to obtain many homogeneous Einstein metrics on groups and homogeneous spaces and study how they can lead to ''spontaneous symmetry breaking''

    The field equations for a Kaluza-Klein Theory with the 4-dimensional space-time embedded in a 4+n dimensional flat space are examined. The integrability conditions for the existence of the embedding, together with Einstein's equations are tentatively interpreted as the field equations for a low energy observer. On the other hand the dynamics for an observer with high energy probes is described by Einstein-Hilbert action. The behaviour of fermion masses is also examined at distinct gravitational field configurations. (Author) [pt

  12. Massless fermions and Kaluza--Klein theory with torsion

    International Nuclear Information System (INIS)

    Wu, Y.; Zee, A.

    1984-01-01

    A pure Kaluza--Klein theory contains no massless fermion in four-dimensional theory. We investigate the effect of introducing torsion on the internal manifold and find that there are massless fermions. The hope is that given an isometry group the representation to which these fermions belong is fixed, in contrast to the situation in Yang--Mills theory. We show that this is indeed the case, but the representations do not appear to be the ones favored by current theoretical prejudice. The cases with parallelizable torsions on a group manifold as the internal manifold are analyzed in detail

  13. On the geometry of Kaluza-Klein theories

    1986-01-01

    Various geometrical aspects of Kaluza-Klein theories are studied for extended space-time manifolds, having the structure of fibre bundles which are associated to principle fibre bundles and whose standard fibres are homogeneous spaces. Distinguished bundle metrics are described and the computation of the corresponding higher dimensional Einstein-Hilbert actions and their dimensional reductions are related to the well-known special case of principal bundles. A transparent geometrical interpretation of results in the physics literature is thus provided and lengthy computations can thereby be avoided. (orig.)

    1998-11-01

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

  19. Some developments from the work of Melanie Klein.

    Spillius, E B

    1983-01-01

    This paper discusses four areas of work in which several followers of Melanie Klein in Britain have developed some of the discoveries and ideas she initiated. First, extension of her concept of projective identification is briefly described, with emphasis on Bion's and Rosenfeld's stress on its communicative as well as its pathological aspects. Second, the extension of Klein's ideas about the epistemophilic instinct, on symbolism, and about projective identification is described in the work of Segal, Bion, Money-Kyrle, and Bick on the development of the capacity to think. Third, certain developments in Kleinian technique are described, with emphasis on the use of the concept of projective identification in analysing transference, and on the analysis of acting out in the transference, a trend contributed to by many Kleinian analysts but perhaps most closely associated with Betty Joseph. Finally, continued refinements in the analysis of the death instinct are briefly described, together with discussion of the changes these refinements have led to in ideas about the organization and relations of parts of the self and internal objects.

    Full Text Available Background. Charcot-Marie-Tooth (CMT disease is a common inherited disorder of the peripheral nervous system. In our paper, different types of CMT are described with their typical clinical pictures, electrophysiological signs and molecular genetic studies. CMT is classified as demyelinative and axonal type and distal motor neuronopathy.Conclusions. CMT can be of autosomal dominant, recessive and X-linked inheritance. The most frequent form of CMT is the result of the dominantly inherited duplication of chromosome 17p11.2 and is marked as CMT1A. The same group involves also rare patients with point mutation in the peripheral myelin protein-22 gene. CMT1B is associated with point mutations in protein zero gene. CMT1C is linked to chromosome 16p13.1–12.3. Patients with point mutations in early growth response 2 gene (EGR2 are included in group CMT1D. The disease can be also inhereted X-linked (CMTX with the mutations in connexin-32 gene. In autosomal recessive inherited demyelinating polyneuropathies (CMT4, mutations are found in the myotubularin-related protein-2 (CMT4B, N-myc downstream-regulated gene 1 (CMT4D, EGR2 (CMT4E, and in the periaksin (CMT4F genes. In axonal inherited neuropathy, mutations are found in KIF1beta (CMT2A and in light neurofilament (CMT2E genes, other forms map to different chromosomal loci (CMT2B, CMT2D, CMT2F. Some suggestions for the diagnostic procedures of patients with CMT are given.

    Full Text Available Julia Kristeva widmet sich im zweiten Teil ihrer Trilogie über das weibliche Genie dem Leben und Werk von Melanie Klein, die mit ihren Arbeiten über die früheste Verfasstheit des Psychischen das psychoanalytische Denken für die Psychosen und den Wahn aufschloss und die Rolle des Mütterlichen im psychoanalytischen Diskurs neu definierte. In ihrer Auseinandersetzung mit Klein gelingt Kristeva nicht nur eine ausgesprochen gelungene Einführung in Kleins Denken, sondern auch eine Analyse weiblicher Intellektualität im 20. Jahrhundert. Zudem werden die Schnittstellen im Denken Kleins und Kristevas sichtbar.Julia Kristeva devotes this second installment of her trilogy on feminine genius to the life and work of Melanie Klein. Klein’s work on the early state of the psyche opened psychoanalytical thinking to psychoses, delusion, and the redefined the role of the motherly in psychoanalytical discourse. In her discussion of Klein, Kristeva provides not only a markedly insightful introduction to Klein’s thinking, but also an analysis of female intellectuality in the 20th century. Moreover, the reader clearly sees the interconnections between Klein and Kristeva’s thinking.

  6. Fissioning universe: Topological inflation and Kaluza-Klein cosmologies

    Energy Technology Data Exchange (ETDEWEB)

    Kaku, Michio; Lykken, J.

    1986-05-05

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

  7. Correspondence between Andreev reflection and Klein tunneling in bipolar graphene

    Beenakker, C. W. J.; Akhmerov, A. R.; Recher, P.; Tworzydło, J.

    2008-02-01

    The Andreev reflection at a superconductor and the Klein tunneling through an n-p junction in graphene are two processes that couple electrons to holes—the former through the superconducting pair potential Δ and the latter through the electrostatic potential U . We derive that the energy spectra in the two systems are identical at low energies ɛ≪Δ and for an antisymmetric potential profile U(-x,y)=-U(x,y) . This correspondence implies that bipolar junctions in graphene may have zero density of states at the Fermi level and carry a current in equilibrium, analogous to the superconducting Josephson junctions. It also implies that nonelectronic systems with the same band structure as graphene, such as honeycomb-lattice photonic crystals, can exhibit pseudosuperconducting behavior.

    We present the most general spherically symmetric solution to the field equations of the truncated five-dimensional Kaluza-Klein theory. We also detail some of the special forms of this solution. With the exception of the Gross-Perry-Sorkin monopole and the Schwarzschild solutions we find that most, and we conjecture all, of the solutions have naked curvature singularities. We then proceed to consider higher-dimensional theories with toroidal compactification and we exhibit a class of nonsingular monopole solutions which are the natural generalization of the Gross-Perry-Sorkin monopole to more than five dimensions. We also present some selected solutions including a solution pertaining to a model with a Ricci-flat, but not curvature-flat, internal manifold. All of these other solutions have naked curvature singularities. (orig.)

    Exact solutions of sine Gordon and multiple sine Gordon equations are constructed in terms of solutions of a linear base equation, the Klein Gordon equation and also in terms of nonlinear base equations where the nonlinearity is polynomial in the dependent variable. Further, exact solutions of nonlinear generalizations of the Schrodinger equation and of additional nonlinear generalizations of the Klein Gordon equation are constructed in terms of solutions of linear base equations. Finally, solutions with spherical symmetry, of nonlinear Klein Gordon equations are given. 14 references

    2011-01-01

    Burt C. Hopkins presents the first in-depth study of the work of Edmund Husserl and Jacob Klein on the philosophical foundations of the logic of modern symbolic mathematics. Accounts of the philosophical origins of formalized concepts-especially mathematical concepts and the process of mathematical abstraction that generates them-have been paramount to the development of phenomenology. Both Husserl and Klein independently concluded that it is impossible to separate the historical origin of the thought that generates the basic concepts of mathematics from their philosophical meanings. Hopkins explores how Husserl and Klein arrived at their conclusion and its philosophical implications for the modern project of formalizing all knowledge.

Hence it is also suitable for Bessel and spherical Bessel functions. Accuracies are in the range 10 -14 -10 -16 in oscillating region, and approx. equal to 10 -30 on an extended precision compiler. The program is suitable for generating Klein-Gordon wavefunctions for matching in pion and kaon physics. (orig.)

  13. Vicious circles of punishment: a reading of Melanie Klein's Envy and gratitude.

    Science.gov (United States)

    Smith, Henry F

    2008-01-01

    Staged as a moral drama, Melanie Klein's Envy and Gratitude (1957) straddles two eras: one reflecting a simpler more concrete, historical method, and the other an approach of greater complexity, focused on the transferential moment. Embedded within the transference are the vicious circles of envy and punishment that are the hallmark of Klein's text. Punishment itself which is always punishment of both self and other, creates its own vicious circle, set in motion by a single act. In the sadomasochistic enactments that result, the moral force of Klein's categories fuels the countertransference. A detailed clinical hour is presented.

    In Paris in 1894, two young physicists fall in love: Marie Sklodowska and Pierre Curie. They get married and make great contributions to science, research radioactivity and discover new chemical elements. The marriage of Marie and Pierre Curie is quite modern: They work together as equals, share their thoughts and pursue their plans together as partners. They share an absolute interest in science, a love of nature, and a sceptic attitude towards the sophisticated society of the Belle Epoque. They are together 24 hours a day with hardly ever any disagreement. Whenever one of them is ill - which is quite often because of the high level of radioactivity in their laboratory -, the other will nurse him or her. After only twelve years of mutual love, Pierre Curie dies. Marie raises their two daughters on her own and continues her research. In 1911, she will be the first scientist that ever gets a second Nobel Prize. (orig.) [de

    Full Text Available Kleine-Levin syndrome is characterized by periodic hypersomnia, hyperphagia, sexual disinhibitions and behavioral disturbances. The prognosis is generally benign, with normal cognitive and social functions after the episodes. We describe a typical case of Kleine-Levin syndrome associated with apparent academic decline, neuropsychological sequelae and personality alterations after the second episode of the illness. Further research in the natural history of Kleine-Levin syndrome is needed, for example, to determine whether early intervention would improve long-term prognosis.A síndrome de Kleine-Levin é caracterizada por hipersônia periódica, hiperfagia, desinibição sexual e outras alterações do comportamento.

The manuscript is discussed in the context of Klein's published work as well as of the relevant contemporary literature. In Klein's view, Don Juan's genitality is determined by oral impulses and fears. By his manic acting out he attempts to ward off a depressive break-down. The paper ends with some reflections about why Klein--ontrary to her intention--failed to revise her manuscript for later publication.

    Full Text Available We consider a collisionless ensemble of classical particles coupled with a Klein-Gordon field. For the resulting nonlinear system of partial differential equations, the relativistic Vlasov-Klein-Gordon system, we prove local-in-time existence of classical solutions and a continuation criterion which says that a solution can blow up only if the particle momenta become large. We also show that classical solutions are global in time in the one-dimensional case.

  16. The rotating dyonic black holes of Kaluza-Klein theory

    Rasheed, D.

    1995-01-01

    The most general electrically and magnetically charged rotating black hole solutions of 5 dimensional Kaluza-Klein theory are given in an explicit form. Various classical quantities associated with the black holes are derived. In particular, one finds the very surprising result that the gyromagnetic and gyroelectric ratios can become arbitrarily large. The thermodynamic quantities of the black holes are calculated and a Smarr-type formula is obtained leading to a generalized first law of black hole thermodynamics. The properties of the extreme solutions are investigated and it is shown how they naturally separate into two classes. The extreme solutions in one class are found to have two unusual properties: (i) Their event horizons have zero angular velocity and yet they have non-zero ADM angular momentum. (ii) In certain circumstances it is possible to add angular momentum to these extreme solutions without changing the mass or charges and yet still maintain an extreme solution. Regarding the extreme black holes as elementary particles, their stability is discussed and it is found that they are stable provided they have sufficient angular momentum. (orig.)

    Emanuel Edward Klein (1844 - 1925) was a British microbiologist of Croatian origin. He was born in Osijek in what is currently the Republic of Croatia and which was then part of the Habsburg Monarchy, he completed his medical studies in Vienna in 1869, and went on to spend his entire career in London. Although trained as an anatomist, embryologist and histologist, his main area of research was microbiology. Due to the fact that back then it was a new and fast developing discipline, he was able to pursue his interests in many directions and make significant discoveries, such as the identification of the 'Bacillus enteritidis sporogenes' as a cause of summer hospital diarrhoeas. Although the overwhelming majority of his researches dealt with bacteria which attacked humans, in 1892 he published a book entitled The Etiology and Pathology of Grouse Disease, Fowl Enteritis, and Some Other Diseases Affecting Birds, which revealed the results of his experiments on the bacteria which affected birds. In the context of the general development of the microbiology, this paper tries to give an objective evaluation of this until now widely neglected book.

  18. Melanie Klein in Buenos Aires: beginnings and developments.

    Etchegoyen, R Horacio; Zysman, Samuel

    2005-06-01

    In the first decades of the 20th century, Freud was known and quoted in Latin America by an elite of enlightened minds. In the 1940s a convergence took place in Buenos Aires of European exiles with local pioneers, and thus the Argentine Psychoanalytical Association was founded in 1942. Since then psychoanalysis has grown steadily and has spread into hospitals and universities, influencing culture at large. The socioeconomic situation of that time permitted this phenomenon to develop, to the astonishment of observers. In this paper the authors study the strong influence of Kleinian thought during the first 30 years of this development. The original works of local thinkers constitute the intellectual capital that sustains the idea of an 'Argentine psychoanalytic school'. During the 1970s, both society and psychoanalysis endured deep and complex changes. Lacan's teachings gained support and Klein's influence began to decline. At present the Buenos Aires Kleinians keep working, while their relationship with Lacanians and other schools is calmer. Respectful discussions became thus possible, oriented to strictly scientific differences.

    Full Text Available Kleine-Levin syndrome (KLS is a rare sleep disorder mainly affecting teenage boys in which the main features are intermittent hypersomnolence, behavioral and cognitive disturbances, hyperphagia, and in some cases hypersexuality. Each episode is of brief duration varying from a week to 1-2 months and affected people are entirely asymptomatic between episodes. No definite cause has been identified, and no effective treatments are available even though illness is having well-defined clinical features. Multiple relapses occur every few weeks or months, and the condition may last for a decade or more before spontaneous resolution. In this study, PubMed was searched and appropriate articles were reviewed to highlight etiology, clinical features, and management of KLS. On the basis of this knowledge, practical information is offered to help clinicians about how to investigate a case of KLS, and what are the possible treatment modalities available currently for the treatment during an episode and interepisodic period for prophylaxis. Comprehensive research into the etiology, pathophysiology, investigation, and treatments are required to aid the development of disease-specific targeted therapies.

    Mary Somerville (1780-1872), after whom Somerville College Oxford was named, was the first woman scientist to win an international reputation entirely in her own right, rather than through association with a scientific brother or father. She was active in astronomy, one of the most demanding areas of science of the day, and flourished in the unique British tradition of Grand Amateurs, who paid their own way and were not affiliated with any academic institution. Mary Somerville was to science what Jane Austen was to literature and Frances Trollope to travel writing. Allan Chapman’s vivid account brings to light the story of an exceptional woman, whose achievements in a field dominated by men deserve to be very widely known.

    Kleine-Levin syndrome (KLS) is a rare, mostly sporadic disorder, characterized by intermittent episodes of hypersomnia plus cognitive and behavior disorders. Although its cause is unknown, multiplex families have been described. We contrasted the clinical and biological features of familial versus sporadic KLS. Two samples of patients with KLS from the United States and France (n = 260) were studied using clinical interviews and human leukocyte antigen (HLA) genotyping. A multiplex family contained two or more first- or second-degree affected relatives (familial cases). Twenty-one patients from 10 multiplex families (siblings: n = 12, including two pairs of monozygotic twins; parent-child: n = 4; cousins: n = 2; uncle-nephews: n = 3) and 239 patients with sporadic KLS were identified, yielding to 4% multiplex families and 8% familial cases. The simplex and multiplex families did not differ for autoimmune, neurological, and psychiatric disorders. Age, sex ratio, ethnicity, HLA typing, karyotyping, disease course, frequency, and duration of KLS episodes did not differ between groups. Episodes were less frequent in familial versus sporadic KLS (2.3 ± 1.8/y versus 3.8 ± 3.7/y, P = 0.004). Menses triggered more frequently KLS onset in the nine girls with familial KLS (relative risk, RR = 4.12, P = 0.03), but not subsequent episodes. Familial cases had less disinhibited speech (RR = 3.44, P = 0.049), less combined hypophagia/hyperphagia (RR = 4.38, P = 0.006), more abrupt termination of episodes (RR = 1.45, P = 0.04) and less postepisode insomnia (RR = 2.16, P = 0.008). There was similar HLA DQB1 distribution in familial versus sporadic cases and no abnormal karyotypes. Familial KLS is mostly present in the same generation, and is clinically similar to but slightly less severe than sporadic KLS. © 2016 Associated Professional Sleep Societies, LLC.

  6. Women who Worked with Marie Curie.

    2015-06-01

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

    Picture taken by Rudiger Voss in the Legal Service LibraryJean-Marie Dufour, CERN Legal Advisor from 1974 until his retirement in 2001, passed away on 8 July. For us, his colleagues in the Legal Service, Jean-Marie was a tutor and a reference, who passed on to us his passion for the practice of law in an intergovernmental organisation. As a boss, his abiding managerial quality was his unstinting loyalty to his collaborators. Jean-Marie joined CERN in 1966 and for the next 35 years was to be the guardian of the Laboratory’s rules. This was his view of the Organization: "...I have discovered [at CERN] a fascinating universe driven by two forces: science and Europe; a world of physicists and engineers who, encouraged by the States of Europe, run a remarkable Laboratory, where Europeans have achieved reconciliation and restored the grand tradition of European physics, attracting physicists from around the world; a Laboratory that transcends not only the fro...

  8. Melanie Klein and Repression: an examination of some unpublished Notes of 1934.

    Science.gov (United States)

    Hinshelwood, R D

    2006-01-01

    Fifteen pages of unpublished Notes were found in the Melanie Klein Archives dating from early 1934, a crucial moment in Klein's development. She was at this time, 1934, moving away from child analysis, whilst also rethinking and revising her allegiance to Karl Abraham's theory of the phases of libidinal development. These Notes, entitled "Early Repression Mechanism," show Klein struggling to develop what became her characteristic theories of the depressive position and the paranoid-schizoid position. Although these Notes are precursors of the paper Klein gave later to the IPA Congress in 1934, they also show the origins of the emphasis she and her followers eventually gave to "splitting" rather than repression. The Notes give us an insight into the way that she worked clinically at the time. We see Klein's confidence develop as she diverged from the classical theories and technique. Her ideas were based on close attention to the detail of her clinical material, rather than attacking theoretical problems directly. The Notes show her method of struggling to her own conclusions, and they offer us a chance to grasp the roots of the subsequent controversy over Kleinian thought.

  9. The origins of disquieting discoveries by Melanie Klein: the possible significance of the case of 'Erna'.

    Science.gov (United States)

    Frank, C; Weiss, H

    1996-12-01

    Using the example of the analysis of 6-year-old Erna, which extended over more than two years and was the longest treatment conducted by Melanie Klein in her Berlin years, the authors demonstrate the importance of her early child analyses for the development of some of her concepts and hence for a decisive advance in psychoanalysis itself. For this purpose they adduce unpublished original documents found among Klein's papers in London, which include autobiographical material, the text of her Würzburg lecture on her obsessional-neurotic little patient, handwritten session notes, and drawings by Erna herself. Although in the author's view Klein attempted to accommodate her findings within Freud's theoretical framework, her clinical experience of the psychic reality of the relational world of early oedipality eventually called for the introduction of new concepts. The combined parent figure, primary sadism, the paranoid-schizoid position, splitting, the relevance of the death drive to the superego, and later formulations on reparation, envy and gratitude are all shown to be foreshadowed in Klein's account of the treatment of Erna. After some retrospective considerations of Erna's analysis and a fleeting glimpse of Erna as an adult, the authors conclude by emphasising the significance of Klein's emigration to England for the subsequent flowering of her work.

    In Paris in 1894, two young physicists fall in love: Marie Sklodowska and Pierre Curie. They get married and make great contributions to science, research radioactivity and discover new chemical elements. The marriage of Marie and Pierre Curie is quite modern: They work together as equals, share their thoughts and pursue their plans together as partners. They share an absolute interest in science, a love of nature, and a sceptic attitude towards the sophisticated society of the Belle Epoque. They are together 24 hours a day with hardly ever any disagreement. Whenever one of them is ill - which is quite often because of the high level of radioactivity in their laboratory -, the other will nurse him or her. After only twelve years of mutual love, Pierre Curie dies. Marie raises their two daughters on her own and continues her research. In 1911, she will be the first scientist that ever gets a second Nobel Prize. (orig.) [German] Im Paris des Jahres 1894 verlieben sich zwei junge Physiker: Marie Sklodowska und Pierre Curie.

  12. Justification of the Nonlinear Schrödinger Approximation for a Quasilinear Klein-Gordon Equation

    Science.gov (United States)

    Düll, Wolf-Patrick

    2017-11-01

    We consider a nonlinear Klein-Gordon equation with a quasilinear quadratic term. The Nonlinear Schrödinger (NLS) equation can be derived as a formal approximation equation describing the evolution of the envelopes of slowly modulated spatially and temporarily oscillating wave packet-like solutions to the quasilinear Klein-Gordon equation. It is the purpose of this paper to present a method that allows one to prove error estimates in Sobolev norms between exact solutions of the quasilinear Klein-Gordon equation and the formal approximation obtained via the NLS equation. The paper contains the first validity proof of the NLS approximation of a nonlinear hyperbolic equation with a quasilinear quadratic term by error estimates in Sobolev spaces. We expect that the method developed in the present paper will allow an answer to the relevant question of the validity of the NLS approximation for other quasilinear hyperbolic systems.

    A spinless particle coupled covariantly to a uniform magnetic field parallel to the string in the background of the rotating cosmic string is studied. The energy levels of the electrically charged particle subject to the Klein-Gordon oscillator are analyzed. Afterwards, we consider the case of the position-dependent mass and show how these energy levels depend on the parameters in the problem. Remarkably, it shows that for the special case, the Klein-Gordon oscillator coupled covariantly to a homogeneous magnetic field with the position-dependent mass in the rotating cosmic string background has the similar behaviors to the Klein-Gordon equation with a Coulomb-type configuration in a rotating cosmic string background in the presence of an external magnetic field.

  14. Good and Bad: Love and Intimacy From Plato to Melanie Klein.

    Science.gov (United States)

    Stromberg, David

    2018-04-11

    Melanie Klein's theories on love outline a complex system of relations-an oscillating dynamic of psychical and emotional tendencies following from both actual experience and fantasies produced by the mind. Her insights are often discussed and applied in psychoanalytical contexts, but the philosophical implications of her theory-especially in relation to Platonic thought-have rarely been discussed. In this article, I will attempt to address this gap by setting out some preliminary yet core considerations shared by both Plato and Klein. First, I will describe some structural parallels between Kleinian and Platonic thought, especially in dialectical terms. Second, I will outline Plato's covert influence on Freud as passing through the teachings of philosopher Franz Brentano. And last, I will discuss intimacy as a struggle between the forces of good and bad, creativity and destruction, and love and hate-suggesting that Klein's conception of love emerges as a moral exigency.

  15. Melanie Klein and Anna Freud: the discourse of the early dispute.

    Science.gov (United States)

    Viner, R

    1996-01-01

    Divisions in the field of the psychoanalysis of children can be traced to a dispute over the infantile super-ego between the theorists Melanie Klein and Anna Freud beginning in 1927. These divisions are understood within the analytic world as the result of scientific disputation between alternative valid theories. An examination of the language, claims, and epistemology of Klein's and Freud's publications in 1927 that marked the public commencement of the conflict, reveals a personalized discourse in which authority was derived from the allegiance, experience, and personal analytic standing of the contestants as much as from theoretical insight. The structure and rhetoric of the debate suggest that, rather than terminating the dispute, the publications of 1927 served to encourage professionalization in child analysis and establish Anna Freud and Melanie Klein as authoritative alternative theorists.

    Kalinowski, M.W.

    1992-01-01

    We present the nonsymmetric Kaluza-Klein and Jordan-Thiry theories as interesting propositions of physics in higher dimensions. We consider the five-dimensional (electromagnetic) case. The work is devoted to a five-dimensional unification of the NGT (nonsymmetric theory of gravitation), electromagnetism, and scalar forces in a Jordan-Thiry manner. We find open-quotes interference effectsclose quotes between gravitational and electromagnetic fields which appear to be due to the skew-symmetric part of the metric. Our unification, called the nonsymmetric Jordan-Thiry theory, becomes the classical Jordan-Thiry theory if the skew-symmetric part of the metric is zero. It becomes the classical Kaluza-Klein theory if the scalar field ρ=1 (Kaluza's Ansatz). We also deal with material sources in the nonsymmetric Kaluza-Klein theory for the electromagnetic case. We consider phenomenological sources with a nonzero fermion current, a nonzero electric current, and a nonzero spin density tensor. From the Palatini variational principle we find equations for the gravitational and electromagnetic fields. We also consider the geodetic equations in the theory and the equation of motion for charged test particles. We consider some numerical predictions of the nonsymmetric Kaluza-Klein theory with nonzero (and with zero) material sources. We prove that they do not contradict any experimental data for the solar system and on the surface of a neutron star. We deal also with spin sources in the nonsymmetric Kaluza-Klein theory. We find an exact, static, spherically symmetric solution in the nonsymmetric Kaluza-Klein theory in the electromagnetic case. This solution has the remarkable property of describing open-quotes mass without massclose quotes and open-quotes charge without charge.close quotes We examine its properties and a physical interpretation. 91 refs., 7 figs

    This work presents a new analytical method for solving Klein-Gordon type equations via Backlund transformations. The method consists in mapping the Klein-Gordon model into a first order system of partial differential equations, which contains a generalized velocity field instead of the Dirac matrices. This system is a tensor model for quantum field theory whose space solution is wider than the Dirac model in the original form. Thus, after finding analytical expressions for the wave functions, the Maxwell field can be readily obtained from the Dirac equations, furnishing a self-consistent field solution for the Maxwell-Dirac system. Analytical and numerical results are reported. (author)

  20. Kaluza--Klein unified field theory and apparent four-dimensional space-time

    International Nuclear Information System (INIS)

    Chyba, C.F.

    1985-01-01

    In the 1920s Kaluza and Klein achieved an elegant unified theory of gravitation and electromagnetism by assuming that space-time is really 5-dimensional. Their approach has since been extended to even higher dimensions in an effort to provide a geometrical unification of all the fundamental interactions. Any such scheme must answer the obvious objection emphasized by Einstein: Why, then, does space-time appear to be only 4-dimensional. This paper provides a semihistorical introduction to Kaluza--Klein unification on a level accessible to those with a basic knowledge of general relativity and particle physics, and examines the progress made in answering Einstein's, and related, objections

    The charge spreading of the ground and excited states of Klein-Gordon particles moving in a Coulomb potential is quantitatively analysed by means of ordinary moments and the Heisenberg measure as well as by using the most relevant information-theoretic measures of global (Shannon entropic power) and local (Fisher information) types. The dependence of these complementary quantities on the nuclear charge Z and the quantum numbers characterizing the physical states is carefully discussed. The comparison of relativistic Klein-Gordon and non-relativistic Schroedinger values is made. Non-relativistic limits at large principal quantum number n and for small values of Z are also reached.

  2. Between practice and theory: Melanie Klein, Anna Freud and the development of child analysis.

    An examination of the early history of child analysis in the writings of Melanie Klein and Anna Freud reveals how two different and opposing approaches to child analysis arose at the same time. The two methods of child analysis are rooted in a differential emphasis on psychoanalytic theory and practice. The Kleinian method derives from the application of technique while the Anna Freudian method is driven by theory. Furthermore, by holding to the Freudian theory of child development Anna Freud was forced to limit the scope of child analysis, while Klein's application of Freudian practice has led to new discoveries about the development of the infant psyche.

    Full Text Available Miguel de Cervantes and Mary Shelley do seem, at first sight, two strange bedfellows. Notwithstanding the evident differences between the narrative of both authors, the English novelist showed a notable interest for the life and works of Miguel de Cervantes throughout her literary career. This article intends to offer a precise portrait of the Cervantean interests of the author of Frankenstein, tracing these through her personal correspondence, her narrative production, and finally, through her contribution to the realm of Cervantean studies: Shelley’s Life of Cervantes (1837, published in Dyonisius Lardner’s Cabinet Cyclopaedia.

  5. Maris polarization in neutron-rich nuclei

    2018-03-01

    We present a theoretical study of the Maris polarization effect and its application in quasi-free reactions to assess information on the structure of exotic nuclei. In particular, we explore the dependence of the polarization effect on neutron excess and neutron-skin thickness. We discuss the uncertainties in the calculations of triple differential cross sections and of analyzing powers due the choices of various nucleon-nucleon interactions and optical potentials and the limitations of the method. Our study implies that polarization variables in (p, 2p) reactions in inverse kinematics can be an effective probe of single-particle structure of nuclei in radioactive-beam facilities.

    2017-07-01

    Attachment theory has developed over many decades - and continues to develop. Its roots lie in several seminal publications of John Bowlby (the basis of attachment theory) and Mary D. S. Ainsworth (the notion of individual differences in attachment). This paper identifies the prescient contributions of these early publications and two processes (a long-term dialogue and reflection on discrepancy) that underlay emergent theory. Because I was a student of Ainsworth when both attachment theory and individual differences in attachment organization were becoming better known, I offer some of my recollections of that period, suggesting how that period may have affected current work in attachment.

    Heritable diseases of the peripheral nerves (Charcot-Marie-Tooth disease [CMT]) affect the motor units and sensory nerves, and they are among the most prevalent genetic conditions in the pediatric patient population. The typical clinical presentation includes distal muscle weakness and atrophy, but the severity and progression are largely variable. Improvements in supportive treatment have led to better preservation of patients' motor functions. More than 80 genes have been associated with CMT. These genetic discoveries, along with the developments of cellular and transgenic disease models, have allowed clinicians to better understand the disease mechanisms, which should lead to more specific treatments.

  17. Optimization of the polarized Klein tunneling currents in a sub-lattice: pseudo-spin filters and latticetronics in graphene ribbons.

    López, Luis I A; Yaro, Simeón Moisés; Champi, A; Ujevic, Sebastian; Mendoza, Michel

    2014-02-12

    We found that with an increase of the potential barrier applied to metallic graphene ribbons, the Klein tunneling current decreases until it is totally destroyed and the pseudo-spin polarization increases until it reaches its maximum value when the current is zero. This inverse relation disfavors the generation of polarized currents in a sub-lattice. In this work we discuss the pseudo-spin control (polarization and inversion) of the Klein tunneling currents, as well as the optimization of these polarized currents in a sub-lattice, using potential barriers in metallic graphene ribbons. Using density of states maps, conductance results, and pseudo-spin polarization information (all of them as a function of the energy V and width of the barrier L), we found (V, L) intervals in which the polarized currents in a given sub-lattice are maximized. We also built parallel and series configurations with these barriers in order to further optimize the polarized currents. A systematic study of these maps and barrier configurations shows that the parallel configurations are good candidates for optimization of the polarized tunneling currents through the sub-lattice. Furthermore, we discuss the possibility of using an electrostatic potential as (i) a pseudo-spin filter or (ii) a pseudo-spin inversion manipulator, i.e. a possible latticetronic of electronic currents through metallic graphene ribbons. The results of this work can be extended to graphene nanostructures.

  18. Roadmap to MaRIE March 2015

    Energy Technology Data Exchange (ETDEWEB)

    Barnes, Cris William [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2015-03-30

    Los Alamos National Laboratory’s proposed MaRIE facility is slated to introduce the world’s highest energy hard x-ray free electron laser (XFEL). As the light source for the Matter-Radiation Interactions in Extremes experimental facility (MaRIE), the 42-keV XFEL, with bursts of x-ray pulses at gigahertz repetition for studying fast dynamical processes, will help accelerate discovery and design of the advanced materials needed to meet 21st-century national security and energy security challenges. Yet the science of free-electron lasers has a long and distinguished history at Los Alamos National Laboratory (LANL), where for nearly four decades Los Alamos scientists have been performing research, design, development, and collaboration work in FEL science. The work at Los Alamos has evolved from low-gain amplifier and oscillator FEL development to highbrightness photoinjector development, and later, self-amplified spontaneous emission (SASE) and high-gain amplifier FEL development.

  19. Stability of Schwarzschild-AdS for the Spherically Symmetric Einstein-Klein-Gordon System

    Science.gov (United States)

    Holzegel, Gustav; Smulevici, Jacques

    2013-01-01

    In this paper, we study the global behavior of solutions to the spherically symmetric coupled Einstein-Klein-Gordon (EKG) system in the presence of a negative cosmological constant. For the Klein-Gordon mass-squared satisfying a ≥ -1 (the Breitenlohner-Freedman bound being a > -9/8), we prove that the Schwarzschild-AdS spacetimes are asymptotically stable: Small perturbations of Schwarzschild-AdS initial data again lead to regular black holes, with the metric on the black hole exterior approaching, at an exponential rate, a Schwarzschild-AdS spacetime. The main difficulties in the proof arise from the lack of monotonicity for the Hawking mass and the asymptotically AdS boundary conditions, which render even (part of) the orbital stability intricate. These issues are resolved in a bootstrap argument on the black hole exterior, with the redshift effect and weighted Hardy inequalities playing the fundamental role in the analysis. Both integrated decay and pointwise decay estimates are obtained. As a corollary of our estimates on the Klein-Gordon field, one obtains in particular exponential decay in time of spherically-symmetric solutions to the linear Klein-Gordon equation on Schwarzschild-AdS.

    In the present paper, we perform Lie and Noether symmetries of the generalized Klein-Gordon-Fock equation. It is shown that the principal Lie algebra, which is one-dimensional, has several possible extensions. It is further shown that several cases arise for which Noether symmetries exist. Exact solutions for some cases are also obtained from the invariant solutions of the investigated equation.

  2. On 'the fear of death' as the primary anxiety: how and why Klein differs from Freud.

    Science.gov (United States)

    Blass, Rachel B

    2014-08-01

    It is well known that Melanie Klein held the view that 'fear of death' is the primary source of anxiety and that her position is explicitly opposed to that of Sigmund Freud, who maintained that that fear cannot in any way or form be a source of anxiety. In a previous article on Freud's Inhibitions, Symptoms and Anxiety (Blass, 2013), the author argued that, counter to what is commonly portrayed in the literature, Freud's considerations for rejecting the fear of death as a source of anxiety were based on relational and experiential factors that are usually associated with Kleinian psychoanalysis. In light of this affinity of Freud with Klein a question arises as to the actual source of their differences in this context. The present paper offers an answer to this question. The author first presents some of her earlier findings on what led Freud to reject the fear of death as a source of anxiety and then turns to investigate Klein's considerations for accepting it. This takes us beyond her explicit statements on this matter and sheds new light on the relationship of her views regarding death and anxiety and those of Freud. In turn this deepens the understanding of the relationship of Freud and Klein's conceptualizations of the psyche and its internal object relations, pointing to both surprising common ground and foundational differences.

  4. Klein-Weyl's program and the ontology of gauge and quantum systems

    Science.gov (United States)

    Catren, Gabriel

    2018-02-01

    We distinguish two orientations in Weyl's analysis of the fundamental role played by the notion of symmetry in physics, namely an orientation inspired by Klein's Erlangen program and a phenomenological-transcendental orientation. By privileging the former to the detriment of the latter, we sketch a group(oid)-theoretical program-that we call the Klein-Weyl program-for the interpretation of both gauge theories and quantum mechanics in a single conceptual framework. This program is based on Weyl's notion of a "structure-endowed entity" equipped with a "group of automorphisms". First, we analyze what Weyl calls the "problem of relativity" in the frameworks provided by special relativity, general relativity, and Yang-Mills theories. We argue that both general relativity and Yang-Mills theories can be understood in terms of a localization of Klein's Erlangen program: while the latter describes the group-theoretical automorphisms of a single structure (such as homogenous geometries), local gauge symmetries and the corresponding gauge fields (Ehresmann connections) can be naturally understood in terms of the groupoid-theoretical isomorphisms in a family of identical structures. Second, we argue that quantum mechanics can be understood in terms of a linearization of Klein's Erlangen program. This stance leads us to an interpretation of the fact that quantum numbers are "indices characterizing representations of groups" ((Weyl, 1931a), p.xxi) in terms of a correspondence between the ontological categories of identity and determinateness.

  15. Patronage in the dispute over child analysis between Melanie Klein and Anna Freud--1927-1932.

    Science.gov (United States)

    Aguayo, J

    2000-08-01

    The author investigates the role of patrons and advocates for Melanie Klein's clinical ideas at the British Psycho-Analytical Society against the backdrop of her theoretical and technical differences with Anna Freud from 1927 to 1932. He also outlines the development of Klein and Anna Freud's theories and techniques within the nascent discipline of child psychoanalysis. The London and Viennese patrons/advocates contributed to polarising what initially were clinical differences about how to analyse pre-latency and latency-age children and which technical processes might best facilitate successful treatment. While the author speculates that a diversity of motivations and agendas may have driven the London group's support for Klein--personal and politicised enthusiasm (Jones), genuine conviction (Riviere) and attempts at theoretical rapprochement between the London and Vienna schools (Glover)--he also argues that Freud's diagnosis with cancer in 1923 and suspicion of patricidal son-successors necessitated the choice of a female successor with unquestioning loyalty to his doctrines. From 1932, when Klein's clinical authority was established, her first group of English supporters began to splinter, as she went on to become a training analyst, mentor and patron in her own right to a succeeding generation of adherents who defended her views during the Controversial Discussions.

    OBJECTIVES: Charcot-Marie-Tooth disease (CMT) is the most common inherited disorder of the peripheral nervous system, yet no studies have compared the mortality in patients with CMT with that of the general population, and prevalence estimates vary considerably. We performed a nationwide register....... The prevalence was estimated by 31 December 2012, and the incidence rate was calculated based on data from 1988 to 2012. We calculated a standardised mortality ratio (SMR) and an absolute excess mortality rate (AER) stratified according to age categories and disease duration. RESULTS: A total of 1534 patients...... a significantly higher SMR in cases below 50 years of age, and in cases with disease duration of more than 10 years. CONCLUSIONS: We found a reduced life expectancy among patients diagnosed with CMT. To our knowledge, this is the first study of CMT to use nationwide register-based data, and the first to report...

    Full Text Available En la conmemoración de la muerte de Nietzsche, ocurrida hace un siglo, conviene tener muy en cuenta su recepción entre nosotros. Es el caso de José Carlos Mariátegui, quien desde posiciones que se podrían ver como antagónicas a las del pensador alemán, hace una asimilación original de motivos nietzscheanos dentro de su concepción revolucionaria. A tal punto que se podría decir que su “marxismo nietzscheano” es el que le posibilita la elaboración del proyecto de un “socialismo indoamericano”. ¿De la confrontación con la “filosofía del martillo” surgirán nuevas propuestas alternativas en el milenio que inauguramos?

  7. Update on Charcot-Marie-Tooth Disease

    Science.gov (United States)

    Patzkó, Ágnes; Shy, Michael E.

    2011-01-01

    Charcot-Marie-Tooth disease (CMT) disease encompasses a genetically heterogeneous group of inherited neuropathies, also known as hereditary motor and sensory neuropathies. CMT results from mutations in more than 40 genes expressed in Schwann cells and neurons causing overlapping phenotypes. The classic CMT phenotype reflects length-dependent axonal degeneration characterized by distal sensory loss and weakness, deep tendon reflex abnormalities, and skeletal deformities. Recent articles have provided insight into the molecular pathogenesis of CMT, which, for the first time, suggest potential therapeutic targets. Although there are currently no effective medications for CMT, multiple clinical trials are ongoing or being planned. This review will focus on the underlying pathomechanisms and diagnostic approaches of CMT and discuss the emerging therapeutic strategies. PMID:21080241

  6. The dialectically constituted/decentred subject of psychoanalysis. II. The contributions of Klein and Winnicott.

    Science.gov (United States)

    Ogden, T H

    1992-01-01

    The present paper focuses on the contributions of Klein and Winnicott to a psychoanalytic conception of the dialectically constituted and decentred subject. Klein's idea of 'positions' represents a conception of the subject constituted in the creative and negating dialectical interplay of fundamentally different modes of attributing meaning to experience. The Kleinian subject is decentred in psychological space and in psychoanalytic time. The concept of projective identification provides the elements of a theory of the creation of the subject in the context of a psychological-interpersonal dialectic. The subject for Winnicott is not coincident with the individual psyche: 'There is no such thing as an infant [apart from the mother]'. Winnicott's notion of the creation of the subject in the psychological space between mother and infant involves a conception of the on-going constitution of the subject in the simultaneity of forms of dialectical tension between at-one-ment and separateness, internality and externality, I and me, I and Thou.

This gives a precise connection...... between phases of Kaluza-Klein black holes and the thermodynamic behavior of the non-gravitational theories dual to near-extremal branes on a circle. In particular, for the thermodynamics of strongly-coupled supersymmetric Yang-Mills theories on a circle we predict the existence of a new non-uniform phase...

  8. Perturbed Coulomb Potentials in the Klein-Gordon Equation: Quasi-Exact Solution

    Science.gov (United States)

    Baradaran, M.; Panahi, H.

    2018-05-01

    Using the Lie algebraic approach, we present the quasi-exact solutions of the relativistic Klein-Gordon equation for perturbed Coulomb potentials namely the Cornell potential, the Kratzer potential and the Killingbeck potential. We calculate the general exact expressions for the energies, corresponding wave functions and the allowed values of the parameters of the potential within the representation space of sl(2) Lie algebra. In addition, we show that the considered equations can be transformed into the Heun's differential equations and then we reproduce the results using the associated special functions. Also, we study the special case of the Coulomb potential and show that in the non-relativistic limit, the solution of the Klein-Gordon equation converges to that of Schrödinger equation.

  9. Fermionic Kaluza-Klein modes in the string-cigar braneworld

    Science.gov (United States)

    Dantas, D. M.; Veras, D. F. S.; Silva, J. E. G.; Almeida, C. A. S.

    2015-11-01

    We study the spin 1 /2 and spin 3 /2 fermion fields in a thick braneworld scenario in six dimensions called string-cigar model. This smooth stringlike model has a source that satisfies the dominant energy condition and undergoes a Ricci flow. We propose a new coupling for the fermions with a background gauge field which allows a smooth and normalized massless mode in the brane with positive tension. By numerical methods the mass spectrum and the massive eigenfunctions are obtained. The Kaluza-Klein massive tower exhibits the usual increasing pattern and, in this scenario, the coupling term does not allow tachyonic Kaluza-Klein states. The brane core and the background gauge field alter the properties of the massive KK tower, enhancing the amplitude of the massive states near the origin and changing the properties of the analogue Schrödinger potential. Furthermore, we find massive modes as resonant states in this scenario for both fermionic fields.

  10. The general Klein-Gordon-Schroedinger system: modulational instability and exact solutions

    International Nuclear Information System (INIS)

    Tang Xiaoyan; Ding Wei

    2008-01-01

    The general Klein-Gordon-Schroedinger (gKGS) system is studied where the cubic auto-interactions are introduced in both the nonlinear Schroedinger and the nonlinear Klein-Gordon fields. We first investigate the modulational instability (MI) of the system, and thus derive the general dispersion relation between the frequency and wavenumber of the modulating perturbations, which demonstrates many possibilities for the MI regions. Using the travelling wave reduction, the gKGS system is greatly simplified. Via a simple function expansion method, we obtain some exact travelling wave solutions. Under some special parameter values, some representative wave structures are graphically displayed including the kink, anti-kink, bright, dark, grey and periodic solitons

  11. Theories on anxiety in Freud and Melanie Klein. Their metapsychological status.

    Science.gov (United States)

    De Bianchedi, E T; Scalozub De Boschan, L; De Cortiñas, L P; De Piccolo, E G

    1988-01-01

    This paper presents a comparative study of the theories on anxiety formulated by Freud and Melanie Klein, with particular emphasis on the questions of its origin, its meaning for the individual and its function in both theoretical systems. The purpose of this comparative analysis is to offer an instrument which helps frame the theoretical discussions in psychoanalysis in an epistemological context. The authors hold that for Freud anxiety is considered as one more amongst the various manifestations of mental life, which his general theories try to explain, whereas for Melanie Klein anxiety and its destinies occupies a central place in her theories on mental functioning. The differences in both theories, which the authors of this paper describe, especially as to origin, function and meaning of anxiety, respond partially to the different metapsychological points of view with which both authors focus mental life--points of view which they have themselves investigated in a previous paper.

  12. Killing spinors for the bosonic string and Kaluza-Klein theory with scalar potentials

    International Nuclear Information System (INIS)

    Liu, Haishan; Lue, H.; Wang, Zhao-Long

    2012-01-01

    The paper consists mainly of two parts. In the first part, we obtain well-defined Killing spinor equations for the low-energy effective action of the bosonic string with the conformal anomaly term. We show that the conformal anomaly term is the only scalar potential that one can add into the action that is consistent with the Killing spinor equations. In the second part, we demonstrate that Kaluza-Klein theory can be gauged so that the Killing spinors are charged under the Kaluza-Klein vector. This gauging process generates a scalar potential with a maximum that gives rise to an AdS spacetime. We also construct solutions of these theories. (orig.)

    Full Text Available Method: The Biographic Narrative Interpretive Method (Prue CHAMBERLAYNE, Joanna BORNAT & Tom WENGRAF, 2000; Tom WENGRAF 2001; Gabriele ROSENTHAL 2004; Kip JONES 2004 uses an interview technique in the form of a single, initial narrative-inducing question (minimalist-passive, for example, "Tell me the story of your life," to elicit an extensive, uninterrupted narration. This shift encompasses willingness on the part of the researcher to cede "control" of the interview scene to the interviewee and assume the posture of active listener/audience participant. A follow-up sub-session can then be used to ask additional questions, but based only on what the interviewee has said in the first interview and using her/his words and phrases in the same order. Through hypothesising how the lived life informs the told story, the case history is then finally constructed from the two separate threads of the "lived life" and the "told story." In this paper, the "lived life" and "told story" are presented in a "raw" form with the further involvement of the reader in mind. The story has not been "analysed" by the interviewer, but left open and transparent. Still, the production of the story becomes the creative output and social construction of both the storyteller and the interviewer (the performer and the audience and, in this case particularly, one story of many stories that could have been told by the person interviewed. Routine facts are often back-grounded by the narrator through the use of this method in favour of spontaneity in the storytelling and the creation of meaningful life metaphors. In this way, the personal journey to "who the interviewee is today" is described, rather than merely a list of accomplishments. The Lived Life: Mary GERGEN (née McCANNEY was born in 1938. The first part of her childhood was spent in the small town of Balaton, Minnesota. She subsequently moved with her family to Minneapolis when she was 12. She attended a suburban middle

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

    Science.gov (United States)

    Hanratty, B; Feather, J; Ward, C

    2000-01-01

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

  2. The Struggle of Integration: James Baldwin and Melanie Klein in the Context of Black Lives Matter

    Directory of Open Access Journals (Sweden)

    David W McIvor

    2016-12-01

    Full Text Available Recent killings of unarmed black citizens are a fresh reminder of the troubled state of racial integration in the United States. At the same time, the unfolding Black Lives Matter protest movements and the responses by federal agencies each testify to a not insignificant capacity for addressing social pathologies surrounding the color line. In order to respond to this ambivalent situation, this article suggests a pairing between the work of James Baldwin and that of the psychoanalyst Melanie Klein. I will argue that we cannot fully appreciate the depths of what Baldwin called the “savage paradox” of race without the insights provided by Klein and object relations psychoanalysis. Conversely, Baldwin helps us to sound out the political significance of object relations approaches, including the work of Klein and those influenced by her such as Hanna Segal and Wilfred Bion. In conversation with the work of Baldwin, object relations theory can help to identify particular social settings and institutions that might allow concrete efforts toward racial justice to take root.

  3. The Cauchy problem for non-linear Klein-Gordon equations

    International Nuclear Information System (INIS)

    Simon, J.C.H.; Taflin, E.

    1993-01-01

    We consider in R n+1 , n≥2, the non-linear Klein-Gordon equation. We prove for such an equation that there is neighbourhood of zero in a Hilbert space of initial conditions for which the Cauchy problem has global solutions and on which there is asymptotic completeness. The inverse of the wave operator linearizes the non-linear equation. If, moreover, the equation is manifestly Poincare covariant then the non-linear representation of the Poincare-Lie algebra, associated with the non-linear Klein-Gordon equation is integrated to a non-linear representation of the Poincare group on an invariant neighbourhood of zero in the Hilbert space. This representation is linearized by the inverse of the wave operator. The Hilbert space is, in both cases, the closure of the space of the differentiable vectors for the linear representation of the Poincare group, associated with the Klein-Gordon equation, with respect to a norm defined by the representation of the enveloping algebra.

  4. The life and work of Melanie Klein in the British Psycho-Analytical Society.

    Science.gov (United States)

    King, P H

    1983-01-01

    This paper describes certain aspects of the life and work of Melanie Klein in the British Psycho-Analytical Society. It attempts to highlight the reciprocity of the relationship between Melanie Klein and other members of that Society by showing how the climate of psychoanalytical opinion that was prevalent among members of that Society during the first decade of her stay in London, and which encouraged discussion of clinical work and interest in psychoanalytical discovery, provided a congenial setting for her to become firmly established as an active member of the British Society and to continue her contributions to psychoanalytic theory and clinical expertise. The paper also traces the development of Melanie Klein's main theoretical contributions, together with relevant criticisms of them as they emerged, against the background of the history of the British Psycho-Analytical Society. It describes the controversies that arose as to whether or not her ideas could properly be viewed within the framework of psychoanalytic theory, as formulated by Freud, and the attempted resolution of these controversies, together with some comments on the repercussions of these theoretical disagreements on relationships within the Society. An extensive list of references is included to facilitate a more detailed study of the subject.

  5. The "new" democratic woman of modernity: Georgia O'Keeffe and Melanie Klein.

    Science.gov (United States)

    Gadt, J C

    1994-06-01

    O'Keeffe put into visual language the psychic splitting that had occurred between the sexes in the United States, attempting to integrate what had formerly been separated as feminine and masculine into the female psyche. In her most important contribution, she explored presence rather than absence and opened up possibilities for thinking about openings. The concept of the female opening in particular had heretofore been assigned a negative meaning, signifying more often than not a gaping wound rather than a space and place of possibilities. Klein's complex and evocative understanding of some of the earliest mental processes of life enabled researchers to delve into the meanings made of the presence of the mother and father and baby, in the context of the baby's body-mind. Klein's female or male baby desires to know from the beginning. She discovered splitting and projective identification, the development of anxiety and guilt under the aegis of these mental processes, the multiple meanings of aggression, and, significantly, she permitted the female baby's body to have its own language. The answers provided by O'Keeffe and Klein bequeathed new possibilities for women's self-invention and remain pivot points for female identity throughout the century, to be confronted again by the second wave of feminism beginning in the late 1960s, by "postfeminist" debates, and by a challenged psychoanalysis. A more careful probing of these issues may help us to better understand our past so as to have greater resources for a more comprehensive reading of our present.

The formulae of these logics are evaluated...... at intervals rather than points and the main eect of that semantic feature is substantially higher expressiveness and computational complexity of the interval logics as compared to point-based ones. Without purporting to provide a comprehensive survey of the field, we take the reader to a journey through...... the main developments in it over the past 10 years and outline some landmark results on expressiveness and (un)decidability of the satisfiability problem for the family of interval logics....

    Full Text Available We report the first episode of Kleine-Levin (KLS syndrome in a 17-year-old male. The illness onset, clinical features, neuropsychological evaluation and polysomnographic recording are described. Typical symptoms hypersomnia, hyperphagia and sexual disinhibition were observed besides behavioral disturbances, polysonographic and neuropsychological alterations. Behavioral disturbances similar to a manic episode including psychotic symptoms were relevant. The pharmacologic treatment included lithium, methylphenidate and risperidone. The introduction of risperidone aimed the control of psychotic symptoms and the persistent manifestations of hypersexuality after sleepness control and to the best of our knowledge there are no other report regarding risperidone use for KLS in the literature.Relatamos o primeiro episódio de síndrome de Kleine-Levin (SKL num adolescente de 17 anos. São descritos o modo de aparecimento da doença, achados clínicos, avaliação neuropsicológica e polissonografia. Foram observados sintomas típicos como hipersonolência, hiperfagia e desinibição sexual, e outras alterações comportamentais, polissonográficas e neuropsicológicas. As alterações comportamentais assemelhadas a um episódio de mania, incluindo sintomas psicóticos, foram relevantes. O tratamento farmacológico incluiu lítio, metilfenidato e risperidona. A introdução de risperidona teve por objetivo o controle dos sintomas psicóticos e das persistentes manifestações da hipersexualidade, que permaneceram após diminuição da sonolência; não temos conhecimento de relatos anteriores, na literatura, de seu uso no tratamento da SKL.

    The peripheral manifestations of the inherited neuropathies are increasingly well characterized, but their effects upon cranial nerve function are not well understood. Hearing loss is recognized in a minority of children with this condition, but has not previously been systemically studied. A clear understanding of the prevalence and degree of auditory difficulties in this population is important as hearing impairment can impact upon speech/language development, social interaction ability and educational progress. The aim of this study was to investigate auditory pathway function, speech perception ability and everyday listening and communication in a group of school-aged children with inherited neuropathies. Twenty-six children with Charcot-Marie-Tooth disease confirmed by genetic testing and physical examination participated. Eighteen had demyelinating neuropathies (Charcot-Marie-Tooth type 1) and eight had the axonal form (Charcot-Marie-Tooth type 2). While each subject had normal or near-normal sound detection, individuals in both disease groups showed electrophysiological evidence of auditory neuropathy with delayed or low amplitude auditory brainstem responses. Auditory perception was also affected, with >60% of subjects with Charcot-Marie-Tooth type 1 and >85% of Charcot-Marie-Tooth type 2 suffering impaired processing of auditory temporal (timing) cues and/or abnormal speech understanding in everyday listening conditions.

    This article focuses on recent advances in Charcot-Marie-Tooth disease, in particular additions to the genetic spectrum, novel paradigms in molecular techniques and an update on therapeutic strategies. Several new Charcot-Marie-Tooth disease-causing genes have been recently identified, further enlarging the genetic diversity and phenotypic variability, including: SBF1, DHTKD1, TFG, MARS, HARS, HINT1, TRIM1, AIFM1, PDK3 and GNB4. The increasing availability and affordability of next-generation sequencing technologies has ramped up gene discovery and drastically changed genetic screening strategies. All large-scale trials studying the effect of ascorbic acid in Charcot-Marie-Tooth 1A have now been completed and were negative. Efforts have been made to design more robust outcome-measures for clinical trials. Promising results with lonaprisan, curcumin and histone deacetylase 6 inhibitors have been obtained in animal models. Charcot-Marie-Tooth is the most common form of inherited peripheral neuropathy and represents the most prevalent hereditary neuromuscular disorder. The genetic spectrum spans more than 70 genes. Gene discovery has been revolutionized recently by new high-throughput molecular technologies. In addition, the phenotypic diversity has grown tremendously. This is a major challenge for geneticists and neurologists. No effective therapy is available for Charcot-Marie-Tooth. Several large trials with ascorbic acid were negative but research into novel compounds continues.

    Full Text Available The Klein Karoo is situated in the Western Cape, South Africa, and is characterised by low rainfall (100–450 mm yr–1. The Klein Karoo is situated in the primary catchment of the Gouritz River. The mean annual runoff (MAR for the three major tributaries of the Gouritz River arising in or feeding the Klein Karoo (Touws, Gamka, Olifants is 540 Mm3 yr–1. Groundwater recharge in the three Klein Karoo catchments is ±257 Mm3 yr–1, but only a portion of this reaches the rivers. The very variable flows result in low 1:50 year yield of 161 Mm3 (30% of MAR. The current demand for water in these catchments is 182 Mm3 yr–1, which exceeds the yield, and demand is projected to increase between 23% and 150% by 2025. Changes in the approach to water management are required, including improving the efficiency of irrigation and land restoration to improve water infiltration and reduce soil erosion. We believe that it is time to change to a water management approach that is designed to anticipate and manage the inherent variability in water resources in the Klein Karoo, thereby placing the region on a path to sustainable development.

    Charcot-Marie-Tooth disease (CMT) is the most common inherited motor and sensory neuropathy. The neuronal form of this disorder is referred to as Charcot-Marie-Tooth type II disease (CMT2). CMT2 is usually inherited as an autosomal dominant trait with a variable age at onset of symptoms associated with progressive axonal neuropathy. In some families, the locus that predisposes to CMT2 has been demonstrated to map to the distal portion of the short arm of chromosome 1. Other families with CMT2 do not show linkage with 1p markers, suggesting genetic heterogeneity in CMT2. We investigated linkage in a single large kindred with autosomal dominant CMT2. The gene responsible for CMT2 in this kindred (CMT2B) was mapped to the interval between the microsatellite markers D3S1769 and D3S1744 in the 3q13-22 region. Study of additional CMT2 kindreds should serve to further refine the disease gene region and may ultimately lead to the identification of a gene defect that underlies the CMT2 phenotype. 21 refs., 3 figs., 1 tab.

  15. Vortex configuration in topological insulators from (1+3) Kaluza-Klein compactification

    Ferreira, Cristine Nunes; Lima, Carlos Eduardo Campos; Helayel-Neto, Jose Abdalla; Paredes, Alfredo A.V.

    2011-01-01

    Full text: Quantum electrodynamics in (1+2)-D is a super-renormalizable gauge theory with some resemblance to four-dimensional theories whenever analyzed in the framework on an 1=N f -expansion. It is possible to show that, by using the fermionic sector of supersymmetric models that result from a (1+3)-D space-time upon compactification, there appears a U(2)-symmetry. We investigate the breakdown study of this symmetry by considering some specific sectors, such as the couplings and the vortex configurations that appear as particular solutions of the model. The construction and the study of models the QCD 3 -type can set up a new bridge of common interests between the condensed matter and high-energy physics communities. The point of view of the condensed matter also helps us to understand materials like graphene, whose description is associated to a massless Dirac equation or topological insulators. The latter, once coupled to vortex configurations, in the low-energy approximation, can generate a mass gap into the Dirac equation through the coupling with fermions. In this work, we consider a Kaluza-Klein compactification from a (1 + 3) supersymmetric model with the Maxwell-Chern-Simons term. The whole motivation behind this contribution is to consider the vortex configuration in (1+2)-D and its coupling to the fermionic sector of the model as a possible interpretation of the topological insulators. As the compactification mechanism adopted is the Kaluza-Klein reduction, we propose an interpretation of the Kaluza- Klein n-modes in connection with the vortices that may be formed in the surface of topological insulators.

    Gao, Tie-Jun; Feng, Tai-Fu; Chen, Jian-Bin

    We discuss the corrections from the Kaluza-Klein (KK) modes to the branching ratio of the rare process bar {B}-> Xsγ in extension of the standard model with a universal extra dimension, which was proposed by Appelquist, Cheng and Dobrescu (ACD). Assuming 1/R≫mW, we sum over the series composed by the KK towers, and get the decoupling result in the limit 1/R→∞. The numerical analysis indicates that the corrections from the KK-excitations to the branching ratio of bar {B}-> Xsγ is about 3.5% as 1/R = 400 GeV.

    We show that the untruncated four-dimensional theory obtained by reducing the (D=5) Einstein action, is a gauge theory of the Virasoro and the Kac-Moody extended Lorentz algebras (deltasub(theta)+SO(1,3)xS 1 (theta)). We write the effective four-dimensional action in closed form and show how its four-dimensional symmetries guarantee its consistency as a system of interacting spin-2 particles which are massless for the unbroken theory and massive for the spontaneously broken one. Finally, we discuss how the Kaluza-Klein prescription circumvents the problems encountered in previous attempts to obtain consistent spin-2-gravity couplings. (author)

    The Maxwell-Dirac system describes the interaction of an electron with its own electromagnetic field. We prove the existence of soliton-like solutions of Maxwell-Dirac in (3+1)-Minkowski space-time. The solutions obtained are regular, stationary in time, and localized in space. They are found by a variational method, as critical points of an energy functional. This functional is strongly indefinite and presents a lack of compactness. We also find soliton-like solutions for the Klein-Gordon-Dirac system, arising in the Yukawa model. (author). 32 refs

    Full Text Available Numerical solutions of the coupled Klein-Gordon-Schrödinger equations is obtained by using differential quadrature methods based on polynomials and quintic B-spline functions for space discretization and Runge-Kutta fourth order for time discretization. Stability of the schemes are studied using matrix stability analysis. The accuracy and efficiency of the methods are shown by conducting some numerical experiments on test problems. The motion of single soliton and interaction of two solitons are simulated by the proposed methods.

    Full Text Available Kleine-Levine Syndrome (KLS is a disorder characterized by a triad of periodic hypersomnia, hyperphagia, and hypersexuality. KLS, although more common in young males, it has also been seen in females. Treatment options available for its management include mood stabilisers like lithium, stimulants like amphetamines, antidepressants and other options including electroconvulsive therapy. Modafinil is one of the new stimulant medications approved for narcolepsy. Herein, we report a young female with KLS and showing favorable response to modafinil. More data is required to establish the effectiveness of modafinil in this syndrome.

    In this paper, we present the exact solution of the (1+1)-dimensional relativistic Klein-Gordon and Dirac equations with linear vector and scalar potentials in the framework of deformed Snyder-de Sitter model. We introduce some changes of variables, we show that a one-dimensional linear potential for the relativistic system in a space deformed can be equivalent to the trigonometric Rosen-Morse potential in a regular space. In both cases, we determine explicitly the energy eigenvalues and their corresponding eigenfunctions expressed in terms of Romonovski polynomials. The limiting cases are analyzed for α 1 and α 2 → 0 and are compared with those of literature.

    Full Text Available Several studies on history, philosophy and sociology of science have demonstrated that science is not autonomous and value-neutral and its selfless search of truth is an ideal theoretical myth far from the real practice of science, which is an aggregate of social practices. Viola Klein was a pioneer in studying science using the same instruments and categories utilized in any other social practice. The aim of this work is to highlight her contributions to Sociology of Scientific Knowledge at a moment when this discipline was, at the most, incipient.

  6. Dirac equation in a de Sitter expansion for massive neutrinos from modern Kaluza-Klein theory

    Sánchez, Pablo Alejandro; Anabitarte, Mariano; Bellini, Mauricio

    2012-01-01

    Using the modern Kaluza-Klein theory of gravity (or the Induced Matter theory), we study the Dirac equation for massive neutrinos on a de Sitter background metric from a 5D Riemann-flat (and hence Ricci-flat) extended de Sitter metric, on which is defined the vacuum for test massless 1/2-spin neutral fields minimally coupled to gravity and free of any other interactions. We obtain that the effective 4D masses of the neutrinos can only take three possible values, which are related to the (static) foliation of the fifth and noncompact extra dimension.

    1984-01-01

    Clarifying the behavior of generic Chern-Simons secondary invariants under infinitesimal variation and finite gauge transformation, it is proved that they are eligible to be a candidate term in the Lagrangian in odd dimensions (2k-1 for gauge theories and 4k-1 for gravity). The coefficients in front of these terms may be quantized because of topological reasons. As a possible application, the dimensional reduction of such actions in Kaluza-Klein theory is discussed. The difficulty in defining the Chern-Simons action for topologically nontrivial field configurations is pointed out and resolved

    Analysts may incorporate many of Melanie Klein's important contributions (e.g., on preoedipal dynamics, envy, and projective identification) without transforming their basic analytic approach. In this paper I argue that adopting the Kleinian notion of unconscious phantasy is transformative. While it is grounded in Freud's thinking and draws out something essential to his work, this notion of phantasy introduces a radical change that defines Kleinian thinking and practice and significantly impacts the analyst's basic clinical approach. This impact and its technical implications in the analytic situation are illustrated and discussed. Copyright © 2017 Institute of Psychoanalysis.

    1991-01-01

    A gauge-invariant Rarita-Schwinger theory of a massive spin-3/2 particle interacting with external electromagnetic, gravitational and dilaton fields is obtained by Kaluza-Klein reduction of a massless Rarita-Schwinger theory with gravitational interaction. Fermionic gauge invariance serves to determine the background equations of motion. The couplings with external fields obtained by the Kaluza-Klein reduction are shown to lead to the absence of the classical Velo-Zwanziger problem and on quantizing using Dirac's procedure, the field anticommutators are found to be positive definite.

  11. Entanglement between smeared field operators in the Klein-Gordon vacuum

    2010-01-01

    Quantum field theory is the application of quantum physics to fields. It provides a theoretical framework widely used in particle physics and condensed matter physics. One of the most distinct features of quantum physics with respect to classical physics is entanglement or the existence of strong correlations between subsystems that can even be spacelike separated. In quantum fields, observables restricted to a region of space define a subsystem. While there are proofs on the existence of local observables that would allow a violation of Bell's inequalities in the vacuum states of quantum fields as well as some explicit but technically demanding schemes requiring an extreme fine-tuning of the interaction between the fields and detectors, an experimentally accessible entanglement witness for quantum fields is still missing. Here we introduce smeared field operators which allow reducing the vacuum to a system of two effective bosonic modes. The introduction of such collective observables is motivated by the fact that no physical probe has access to fields in single spatial (mathematical) points but rather smeared over finite volumes. We first give explicit collective observables whose correlations reveal vacuum entanglement in the Klein-Gordon field. We then show that the critical distance between the two regions of space above which two effective bosonic modes become separable is of the order of the Compton wavelength of the particle corresponding to the massive Klein-Gordon field.

  12. The ideal and the real in Klein and Milton: some observations on reading Paradise Lost.

    Science.gov (United States)

    Steiner, John

    2013-10-01

    Extracts from Paradise Lost (Milton 1674) are presented to illustrate some ideas of mutual interest to poets and psychoanalysts. In particular, Milton portrays the distinction between the human and the divine in terms of God's perfection and omnipotence, in contrast to man's imperfections. Recognition of this difference can open a painful gap between the self and the ideal, leading to attempts to bridge it via omnipotence. Because we imbue our objects with omnipotence, a similar gap can arise between adult and child and between patient and analyst. Klein's description of the ideal good object highlights similar issues. Both Klein and Milton present the ideal as something important to internalize as a foundation for hope, trust, and belief in goodness, and both emphasize the ideal as something that can be aspired to but not omnipotently realized. Facing this distinction requires a capacity to relinquish and mourn the loss of the good object, as well as the loss of the omnipotence that made possession of it possible. © 2013 The Psychoanalytic Quarterly, Inc.

    We consider Randall-Sundrum scenarios based on SU(2){sub L} x SU(2){sub R} and a discrete parity exchanging L with R. The custodial and parity symmetries can be used to make the tree level contribution to the T parameter and the anomalous couplings of the bottom quark to the Z very small. We show that the resulting quantum numbers typically induce a negative T parameter at one loop that, together with the positive value of the S parameter, restrict considerably these models. There are nevertheless regions of parameter space that successfully reproduce the fit to electroweak precision observables with light Kaluza-Klein excitations accessible at colliders. We consider models of gauge-Higgs unification that implement the custodial and parity symmetries and find that the electroweak data singles out a very well defined region in parameter space. In this region one typically finds light gauge boson Kaluza-Klein excitations as well as light SU(2){sub L} singlet, and sometimes also doublet, fermionic states, that mix with the top quark, and that may yield interesting signatures at future colliders.

    Full Text Available Objective: to draw the attention to the Kleine - Levin syndrome (SKL, a rare, poorly understood disease, not only in Russia but throughout the world. We analyzed the case of the 23-year old patient M, with the Kleine — Levin syndrome. SKL belongs to the group of recurrent hypersomnia and is characterized by long bouts of sleep lasting an average of 10-14 days, beginning with the imperative and difficulty awakening. During bouts of sleep observed unusual behavior of patients: hyperphagia; hypersexuality in males; irritability, restlessness, impaired mental activity; aggression; feeling of unreality of it all; confusion, hallucinatory episodes and depression in females. During wakefulness, marked dyspho-ria, emotional stupefaction, loss of memory. The syndrome develops in 4 times more often in men than in women, aged 12-25 years. Etiological factors: brain tumor, head trauma, metabolic disorders, acute infectious diseases with fever. Often the development of the syndrome is preceded by hyperemia and hypothalamic-pituitary dysfunction. The article discussed the etiology, diagnosis, and possible combinations of clinical manifestations in SKL.

His researches were in the fields of anatomy, histology, pathology, embryology, physiology, and especially microbiology. He did a great deal to its development in Britain. He has written about 260 scientific papers on a broad range of different topics. Despite all the aforementioned facts, his work was never properly studied, and he is almost unknown outside academic circles. For that reason, attitudes towards him still range between the extremes of calling him the father of British microbiology on one side, and attributing him as a diligent and idustrious plodder on the other. In this paper we will try to prove the first attitude. We will put his researches in a general context. Finally we will highlight his original achievements in the isolation of new microbes.

    Full Text Available Kleine-Levin syndrome (KLS is a rare sleep disorder mainly affecting teenage boys in which the main features are intermittent hypersomnolence, behavioral and cognitive disturbances, hyperphagia, and in some cases hyper sexuality. Etiology is unknown, and there is no specific clinical or imaging test for this syndrome even though the illness has well-defined clinical features. Also, there is no effective treatment for KLS. KLS is self-limited, so the prognosis for these patients is not so bad. This study presents our case report and comprehensive workout that led to diagnosis which is primarily clinical. Our patient is a 20-year-old man referred to our clinic because of sleeping problems. At the age of 14, he presented with complaints of the excessive duration of sleep, increased appetite, excessive daytime sleepiness, loss of interest in social activities during attendance of high school and hallucinations. The excessive diagnostic procedure does not find pathological. Kleine-Levin syndrome (KLS is a rare sleep disorder of unknown etiology which diagnosis is clinical and diagnostic workup is mainly to exclude other similar conditions. There is no specific therapy, but the disease is self-limited and with good prognosis.

    2010-02-01

    In the work of Kerner et al. (Phys Rev D 63:027502, 2001) the problem of the geodesic deviation in a 5D Kaluza-Klein background is faced. The 4D space-time projection of the resulting equation coincides with the usual geodesic deviation equation in the presence of the Lorenz force, provided that the fifth component of the deviation vector satisfies an extra constraint which takes into account the q/ m conservation along the path. The analysis was performed setting as a constant the scalar field which appears in Kaluza-Klein model. Here we focus on the extension of such a work to the model where the presence of the scalar field is considered. Our result coincides with that of Kerner et al. when the minimal case {φ=1} is considered, while it shows some departures in the general case. The novelty due to the presence of {φ} is that the variation of the q/ m between the two geodesic lines is not conserved during the motion; an exact law for such a behaviour has been derived.

  18. Solutions of the Klein-Gordon equation on manifolds with variable geometry including dimensional reduction

    Science.gov (United States)

    Fiziev, P. P.; Shirkov, D. V.

    2011-05-01

    We develop the recent proposal to use dimensional reduction from the four-dimensional space-time (D = 1 + 3) to the variant with a smaller number of space dimensions D = 1 + d, d < 3, at sufficiently small distances to construct a renormalizable quantum field theory. We study the Klein-Gordon equation with a few toy examples ("educational toys") of a space-time with a variable spatial geometry including a transition to a dimensional reduction. The examples considered contain a combination of two regions with a simple geometry (two-dimensional cylindrical surfaces with different radii) connected by a transition region. The new technique for transforming the study of solutions of the Klein-Gordon problem on a space with variable geometry into solution of a one-dimensional stationary Schrödinger-type equation with potential generated by this variation is useful. We draw the following conclusions: ( 1) The signal related to the degree of freedom specific to the higher-dimensional part does not penetrate into the smaller-dimensional part because of an inertial force inevitably arising in the transition region (this is the centrifugal force in our models). ( 2) The specific spectrum of scalar excitations resembles the spectrum of real particles; it reflects the geometry of the transition region and represents its "fingerprints." ( 3) The parity violation due to the asymmetric character of the construction of our models could be related to the CP symmetry violation.

  19. On the infinite-dimensional spin-2 symmetries in Kaluza-Klein theories

    International Nuclear Information System (INIS)

    Hohm, O.; Hamburg Univ.

    2005-11-01

    We consider the couplings of an infinite number of spin-2 fields to gravity appearing in Kaluza-Klein theories. They are constructed as the broken phase of a massless theory possessing an infinite-dimensional spin-2 symmetry. Focusing on a circle compactification of four-dimensional gravity we show that the resulting gravity/spin-2 system in D=3 has in its unbroken phase an interpretation as a Chern-Simons theory of the Kac-Moody algebra iso(1,2) associated to the Poincare group and also fits into the geometrical framework of algebra-valued differential geometry developed by Wald. Assigning all degrees of freedom to scalar fields, the matter couplings in the unbroken phase are determined, and it is shown that their global symmetry algebra contains the Virasoro algebra together with an enhancement of the Ehlers group SL(2,R) to its affine extension. The broken phase is then constructed by gauging a subgroup of the global symmetries. It is shown that metric, spin-2 fields and Kaluza-Klein vectors combine into a Chern-Simons theory for an extended algebra, in which the affine Poincare subalgebra acquires a central extension.

  20. THE STUDY AND TREATMENT OF MOTHERS AND INFANTS, THEN AND NOW: MELANIE KLEIN'S "NOTES ON BABY" IN A CONTEMPORARY PSYCHOANALYTIC CONTEXT.

    Science.gov (United States)

    Aguayo, Joseph; Salomonsson, Björn

    2017-04-01

    This paper draws on Melanie Klein's (unpublished) observational notes of her infant grandson, written primarily in 1938 and 1939. Apart from moving glimpses into a young family's life, the notes contain astute observations of an infant's behavior and emotions. Compared with Klein's published writings, the style is less theoretical and polemical. Later, in his latency years, Klein's grandson was in analysis with Marion Milner, who in 1952 published a paper drawing on the treatment. The present paper focuses on (1) how observations and treatment of the same child and his family by clinicians in close relationships with each other (Klein, Milner, and Winnicott) fertilized reciprocal influence but also brought into question the validity of Klein's observations, and (2) the relative merits and contributions of various modalities in understanding the infant's psyche, including experimental research, direct observation, parent-infant psychotherapy, and reconstructions from older patients-as occurs, for example, in psychoanalysis. © 2017 The Psychoanalytic Quarterly, Inc.

  3. Rosie Carpe and the Virgin Mary: Modelling Modern Motherhood

    Directory of Open Access Journals (Sweden)

    Pauline Eaton

    2016-06-01

    Full Text Available Marie NDiaye’s 2001 novel, Rosie Carpe, incorporates, as one of its several instances of parenting failure, the narrative of the decline of a single mother from adequacy to abuse. This narrative, which is the focus of this article, might be said to put flesh on the bones of Julia Kristeva’s deconstruction of the Virgin Mary in her 1980s essay ‘Stabat Mater’. Kristeva saw the Marian model as out of date but she interrogated its enduring power and its continuing influence on our cultural perceptions of maternity. NDiaye’s eponymous Rosie realises she is pregnant but has no idea how this has come about. Rosie is not represented as a woman who has a religious faith but she decides to accept her child as a holy miracle. This article analyses how the ‘mythology’ of the Virgin Mary, and other biblical intertext, is woven into the narrative of Rosie’s experience of motherhood, so as to counterpoint and illuminate Rosie’s bleak and raw inner experience of maternity, an experience which, while confirming that Rosie is not, and never could have been, a modern Virgin Mary nevertheless refreshes the human stories at the root of the Christian narrative.

  2. Mother and child. A psychobiographical portrait of Mary Cassatt.

    Science.gov (United States)

    Zerbe, K J

    1987-01-01

    The noted American impressionist, Mary Cassatt is remembered for her intimate portrayal of women, children, and the mother-child relationship. In this paper I have attempted to highlight some of the psychological forces impinging upon the artist, feeling that the artist's work is highly overdetermined. Mention was made of some of the difficulties that a psychobiographical study engenders. Nevertheless, it is hoped that such a study leads to enhanced understanding and appreciation of the artist, her work, and her rich inner world. An examination of the artist's life indicates that difficulties in the family of origin impinged upon her and deeply influenced her work. The loss of several siblings during critical developmental subphases may have produced intense survival guilt in Mary, motivating her to "recreate" her siblings on canvas and to devote her life to care of survivors. Lack of confirmation of Mary's talents by her father may have hindered her development, propelling the child toward a profoundly libidinalized and enmeshed relationship with the mother. Mary's intense relationship with her mother may have led the artist to develop particular stylistic nuances in her productions, contributed to her inability to become a wife and mother herself, and led to frequent episodes of depression. A case was made that Mary suffered from narcissistic disturbance, never completing the recognition of herself as a person outside of the orbit of her mother. Finally, the role of Edgar Degas in the artist's life was described. He seems to have played a major role in the evolution of Mary's style as well as being an important influence in her making a partial separation from her mother in adulthood. In spite of Mary's deep personal suffering, she was able to epitomize in her paintings the most tender and nurturant of relationships. By painting the mother-child theme, she sublimated her own wishes to become a mother as creator of art. Within her family system, she appropriated

    Kleine-Levin syndrome is characterized by relapsing-remitting episodes of severe hypersomnia, cognitive impairment, apathy, derealization and behavioural disturbances. Between episodes, patients have normal sleep, mood and behaviour. Functional imaging studies performed in small series of patients with Kleine-Levin syndrome with visual or semi-quantitative, uncontrolled analysis yielded equivocal brain changes. Using whole brain voxel-based group analysis, we compared brain perfusion scintigraphy during and between episodes in consecutive patients with Kleine-Levin syndrome versus healthy control subjects and correlated perfusion changes with disease severity and symptoms, focusing on less studied but disabling symptoms, such as apathy and derealization. During asymptomatic periods, 41 patients (mean age of 22.3 ± 8.1 years, 56.1% male) and 15 age- and sex-matched healthy control subjects underwent single-photon emission computed tomography scanning with technetium-99m ethyl cysteinate dimer. Eleven patients repeated the test during a symptomatic period. Compared with controls, patients during asymptomatic periods had persistent hypoperfusion in the hypothalamus, the thalamus (mainly the right posterior part), the caudate nucleus, and cortical associative areas, including the anterior cingulate, (Brodmann area 25), the orbito-frontal (Brodmann area 11) and the right superior temporal cortices (Brodmann area 22), extending to the insula (P area). Two additional hypoperfused areas emerged during symptomatic periods (P Brodmann area 8) and the right parieto-temporal junction (Brodmann areas 22 and 39). These two areas were more affected between episodes, when the mean episode duration was longer (r = -0.53; P area may underlie the striking derealization reported by patients during episodes. Defects in the dorsomedial prefrontal cortex may cause apathy. Persistent hypoperfusion in the diencephalic and associative cortical area during asymptomatic periods is a marker

In this book an overview is given of the academic world at that time: limited access to universities for women, the carriers of both women in physics and their pioneering research and discoveries, the refusal of Marie Curie by the French Academy of Sciences, the awarding of the Nobel Prize and the assignment of Irene Joliot-Curie as the first female minister in France, the impact of the two World Wars, their married and private lives and the constant smear campaign of the press against both women. The lives and works of both women are hold against the light of the present position of women in physical sciences. [Dutch] In 1903, precies honderd jaar geleden, ontving Marie Curie als eerste vrouw de Nobelprijs voor de Wetenschap, gevolgd door een tweede Nobelprijs in 1911.

Marie and Irene Curie schetst een breed beeld van de academische wereld waarin beide vrouwen zich bewogen: de beperkte toegang van vrouwen tot de universiteit, hun carrisres in de natuurkunde en baanbrekende ontdekkingen, de afwijzing van Marie door de Franse Academie des Sciences, de toekenning van de Nobelprijs en de benoeming van Irene als eerste vrouwelijke minister in Frankrijk, de invloed van de twee Wereldoorlogen, hun huwelijks- en priveleven en de niet aflatende hetze van de pers tegen beiden.

  12. An unusual occurrence of Kleine-Levin syndrome in a man with refractory immune thrombocytopenic purpura: a case report.

    Kleine-Levin syndrome is an extremely rare neurological entity characterized by recurrent episodes of hypersomnia which are sometimes associated with compulsive hyperphagia and behavioral changes. Autoimmunity has recently been proposed as a factor contributing to its pathogenesis. Immune thrombocytopenic purpura is a relatively common autoimmune disease showing a lot of complexity and uncertainty regarding its treatment regimens and its refractory nature in some cases. A 32-year-old Persian White man visited his private hematologist complaining of recent episodes of epistaxis and appearance of petechial lesions 24 hours after receiving a meningococcal vaccine. He had a history of immune thrombocytopenic purpura 13 years before his presentation. Based on his history and laboratory findings, his condition was diagnosed as a relapse of immune thrombocytopenic purpura and was managed accordingly. He did not respond to first-line corticosteroid regimens and later developed neurological symptoms as recurrent episodes of hypersomnia and hyperphagia. After a complete clinical and paraclinical evaluation and ruling out other possible conditions, he was given a diagnosis of Kleine-Levin syndrome. He was followed up for his immune thrombocytopenic purpura and received different treatment regimens none of which were adequately successful except intravenous immunoglobulin that was only temporarily effective. He has had 4 documented self-limited episodes of Kleine-Levin syndrome since his initial presentation. Immune thrombocytopenic purpura may be associated with meningococcal vaccination in adulthood. Responses to treatment in immune thrombocytopenic purpura vary among patients. Our patient only had a transient acceptable response to intravenous immunoglobulin while all other options failed to improve his platelet count. Concurrence of immune thrombocytopenic purpura and Kleine-Levin syndrome supports the role of autoimmunity as the proposed pathophysiological mechanism of

  13. Cosmological bounds on large extra dimensions from nonthermal production of Kaluza-Klein modes

    International Nuclear Information System (INIS)

    Allahverdi, Rouzbeh; Bird, Chris; Groot Nibbelink, Stefan; Pospelov, Maxim

    2004-01-01

    The existing cosmological constraints on theories with large extra dimensions rely on the thermal production of the Kaluza-Klein (KK) modes of gravitons and radions in the early Universe. Successful inflation and reheating, as well as baryogenesis, typically requires the existence of a TeV-scale field in the bulk, most notably the inflaton. The nonthermal production of KK modes with masses of order 100 GeV accompanying the inflaton decay sets the lower bounds on the fundamental scale M * . For a 1-TeV inflaton, the late decay of these modes distorts the successful predictions of big bang nucleosynthesis unless M * >35, 13, 7, 5, and 3 TeV for two, three, four, five, and six extra dimensions, respectively. This improves the existing bounds from cosmology on M * for four, five, and six extra dimensions. Even more stringent bounds are derived for a heavier inflaton

  14. Constraints on the size of the extra dimension from Kaluza-Klein gravitino decay

    International Nuclear Information System (INIS)

    Gherson, David

    2007-01-01

    We study the consequences of the gravitino decay into dark matter. We suppose that the lightest neutralino is the main component of dark matter. In our framework the gravitino is heavy enough to decay before big bang nucleosynthesis starts. We consider a model coming from a five dimensional supergravity compactified on S 1 /Z 2 with gravity in the bulk and matter localized on tensionless branes at the orbifold fixed points. We require that the dark matter, which is produced thermally and in the decay of Kaluza-Klein modes of the gravitino, has an abundance compatible with observation. We deduce from our model that there are curves of constraints between the size of the extra dimension and the reheating temperature of the Universe after inflation

    The engineering of cooling mechanisms is a bottleneck in nanoelectronics. Thermal exchanges in diffusive graphene are mostly driven by defect-assisted acoustic phonon scattering, but the case of high-mobility graphene on hexagonal boron nitride (hBN) is radically different, with a prominent contribution of remote phonons from the substrate. Bilayer graphene on a hBN transistor with a local gate is driven in a regime where almost perfect current saturation is achieved by compensation of the decrease in the carrier density and Zener-Klein tunnelling (ZKT) at high bias. Using noise thermometry, we show that the ZKT triggers a new cooling pathway due to the emission of hyperbolic phonon polaritons in hBN by out-of-equilibrium electron-hole pairs beyond the super-Planckian regime. The combination of ZKT transport and hyperbolic phonon polariton cooling renders graphene on BN transistors a valuable nanotechnology for power devices and RF electronics.

  16. Moving discrete breathers in a Klein-Gordon chain with an impurity

    2002-01-01

    We analyse the influence of an impurity in the evolution of moving discrete breathers in a Klein-Gordon chain with non-weak nonlinearity. Three different types of behaviour can be observed when moving breathers interact with the impurity: they pass through the impurity continuing their direction of movement; they are reflected by the impurity; they are trapped by the impurity, giving rise to chaotic breathers, as their Fourier power spectra show. Resonance with a breather centred at the impurity site is conjectured to be a necessary condition for the appearance of the trapping phenomenon. This paper establishes a difference between the resonance condition of the non-weak nonlinearity approach and the resonance condition with the linear impurity mode in the case of weak nonlinearity

  17. All the Four-Dimensional Static, Spherically Symmetric Solutions of Abelian Kaluza-Klein Theory

    International Nuclear Information System (INIS)

    Cvetic, M.; Youm, D.

    1995-01-01

    We present the explicit form for all the four-dimensional, static, spherically symmetric solutions in (4+n)-d Abelian Kaluza-Klein theory by performing a subset of SO(2,n) transformations corresponding to four SO(1,1) boosts on the Schwarzschild solution, supplemented by SO(n)/SO(n-2) transformations. The solutions are parametrized by the mass M, Taub-NUT charge a, and n electric rvec Q and n magnetic rvec P charges. Nonextreme black holes (with zero Taub-NUT charge) have either the Reissner-Nordstroem or Schwarzschild global space-time. Supersymmetric extreme black holes have a null or naked singularity, while nonsupersymmetric extreme ones have a global space-time of extreme Reissner-Nordstroem black holes. copyright 1995 The American Physical Society

    Full Text Available It was known for quite long time that a quaternion space can be generalized to a Clifford space, and vice versa; but how to find its neat link with more convenient metric form in the General Relativity theory, has not been explored extensively. We begin with a representation of group with non-zero quaternions to derive closed FLRW metric [1], and from there obtains Carmeli metric, which can be extended further to become 5D and 6D metric (which we propose to call Kaluza-Klein-Carmeli metric. Thereafter we discuss some plausible implications of this metric, beyond describing a galaxy’s spiraling motion and redshift data as these have been done by Carmeli and Hartnett [4, 5, 6]. In subsequent section we explain Podkletnov’s rotating disc experiment. We also note possible implications to quantum gravity. Further observations are of course recommended in order to refute or verify this proposition.

    We introduce a class of infinite dimensional algebras with a 'generalized loop structure' by considering the global symmetries of the four dimensional Lagrangian obtained by compactifying general relativity coupled to Yang-Mills in six dimensions down to M 4 xS 2 . The generalization to arbitrary dimensions is then obvious. We show by explicit construction that such algebras possess an infinite number of finite sub-algebras. Among which, for the six dimensional case, is so(1,3) realized on S 2 with vanishing Casimir invariants. This so(1,3) may be interpreted, in accord with a previous conjecture of Salam and Strathdee [Ann. Phys. 141, 316(1982)], as the 'ladder' symmetry for the Kaluza-Klein towers. (author)

  1. Finite temperature Casimir effect for a massless fractional Klein-Gordon field with fractional Neumann conditions

    Eab, C. H.; Lim, S. C.; Teo, L. P.

    2007-01-01

    This paper studies the Casimir effect due to fractional massless Klein-Gordon field confined to parallel plates. A new kind of boundary condition called fractional Neumann condition which involves vanishing fractional derivatives of the field is introduced. The fractional Neumann condition allows the interpolation of Dirichlet and Neumann conditions imposed on the two plates. There exists a transition value in the difference between the orders of the fractional Neumann conditions for which the Casimir force changes from attractive to repulsive. Low and high temperature limits of Casimir energy and pressure are obtained. For sufficiently high temperature, these quantities are dominated by terms independent of the boundary conditions. Finally, validity of the temperature inversion symmetry for various boundary conditions is discussed

  3. Remarks on a five-dimensional Kaluza-Klein theory of the massive Dirac monopole

    2005-01-01

    The Gross-Perry-Sorkin spacetime, formed by the Euclidean Taub-Newman-Unti-Tamburino space with the time trivially added, is the appropriate background of the Dirac magnetic monopole without an explicit mass term. We show that there exists a very simple five-dimensional metric of spacetimes carrying massive magnetic monopoles that is an exact solution of the vacuum Einstein equations. Moreover, the same isometry properties as the original Euclidean Taub-Newman-Unti-Tamburino space are preserved. This leads to an Abelian Kaluza-Klein theory whose metric appears as a combination between the Gross-Perry-Sorkin and Schwarzschild ones. The asymptotic motion of the scalar charged test particles is discussed, now by accounting for the mixing between the gravitational and magnetic effects

    Objectives To analyze the representations of the nurse and individual in mental suffering portrayed in the photographic work by Steven Klein, in the USAnatomy exhibit held at the Museum of Sculpture (Museu da escultura) in São Paulo, in 2011. Methods Qualitative study carried out in 2012. Three photographs were submitted to iconographic analysis. The interpretation of the findings was based on theoretical frameworks of Foucault and Bourdieu on power relations. Results The nurse is represented as a sensual, insensitive person, with the power to control and torture while the person in psychological distress is represented as dirty, imprisoned and subjected to an asymmetrical relationship of power with the nurse. Final considerations Relationships of submission and symbolic dominance, in which the person in psychological distress has their body molded by discipline imposed by the nurse. Stereotypes of the image of the nurse oppose the ideology of the profession, which is to ensure the integrity of those being cared for.

    2007-07-01

    Full Text Available Analysis of covariant derivatives of vectors in quaternion (Q- spaces performed using Q-unit spinor-splitting technique and use of SL(2C-invariance of quaternion multiplication reveals close connexion of Q-geometry objects and Yang-Mills (YM field principle characteristics. In particular, it is shown that Q-connexion (with quaternion non-metricity and related curvature of 4 dimensional (4D space-times with 3D Q-space sections are formally equivalent to respectively YM-field potential and strength, traditionally emerging from the minimal action assumption. Plausible links between YM field equation and Klein-Gordon equation, in particular via its known isomorphism with Duffin-Kemmer equation, are also discussed.

  7. Hadamard States for the Klein-Gordon Equation on Lorentzian Manifolds of Bounded Geometry

    Gérard, Christian; Oulghazi, Omar; Wrochna, Michał

    2017-06-01

    We consider the Klein-Gordon equation on a class of Lorentzian manifolds with Cauchy surface of bounded geometry, which is shown to include examples such as exterior Kerr, Kerr-de Sitter spacetime and the maximal globally hyperbolic extension of the Kerr outer region. In this setup, we give an approximate diagonalization and a microlocal decomposition of the Cauchy evolution using a time-dependent version of the pseudodifferential calculus on Riemannian manifolds of bounded geometry. We apply this result to construct all pure regular Hadamard states (and associated Feynman inverses), where regular refers to the state's two-point function having Cauchy data given by pseudodifferential operators. This allows us to conclude that there is a one-parameter family of elliptic pseudodifferential operators that encodes both the choice of (pure, regular) Hadamard state and the underlying spacetime metric.

    1992-01-01

    In the framework of heat-kernel approach to zeta-function regularization, in this paper the one-loop effective potential at finite temperature for scalar and spinor fields on Kaluza-Klein space-time of the form M p x M c n , where M p is p-dimensional Minkowski space-time is evaluated. In particular, when the compact manifold is M c n = H n /Γ, the Selberg tracer formula associated with discrete torsion-free group Γ of the n-dimensional Lobachevsky space H n is used. An explicit representation for the thermodynamic potential valid for arbitrary temperature is found. As a result a complete high temperature expansion is presented and the roles of zero modes and topological contributions is discussed

  9. Some observations on hallucination: clinical application of some developments of Melanie Klein's work.

    Science.gov (United States)

    Taylor, D

    1983-01-01

    The analysis of a psychotic patient is used to illustrate the importance of certain developments of Melanie Klein's work. The case presentation focuses upon the formal qualities of the patient's communications, many of which were amalgamations of profoundly incompatible elements, particularly a subtle destructiveness which parasitized seemingly impartial reports about her state of mind. These communications embodied important object relationships. The patient used her communications to conjure up psychic disintegration. As a result of her involvement in 'chuntering' her preoccupations would become increasingly violent, cruel and sexualized. The patient's equivocal communications generate confusion. This is central to the patient's experience of self-destruction as persecution. A number of ideas are advanced concerning the origins of the patient's hallucinations. These include her relish at the introduction of sensory distortions. Questions are raised about the nature of certain types of hallucination, the origins and intractability of concrete thinking, about verbalization and about the typology of psychotic patients.

    Many deltas in the world are subject to drowning and loss of land due to accelerated soil subsidence, sea level rise, and sediment starvation. Effective delta restoration requires a thorough understanding of the rates and mechanisms of delta aggradation and their controls. This study aims to quantify the rates and patterns of aggradation in the Kleine Noordwaard, a former polder area in the Biesbosch area in the south-west of the Netherlands, in which water and sediment have been reintroduced since 2009. A sediment budget was established using existing bathymetric data collected using a multibeam echosounder and LiDAR digital elevation models collected since the opening of the polder, supplemented with field observations of the location and height of cut banks carried out between July and December 2014. Consecutive measurements of channel bathymetry showed a positive sediment budget in the channels between March 2009 and March 2013. During this period 59533 m3 of sediment was retained in the channels in the Kleine Noordwaard, which corresponds to an average sedimentation rate of 16.8 mm/year in the channels and 3.4 mm/year over the entire area. Sedimentation and aggradation primarily took place in the channels in the central part of the former polder area, whereas the channels near the entrance and outlet of the area underwent considerable erosion. It is therefore likely that a part of the sediment deposited in the central part of the system was supplied internally by upstream erosion of the channels. The results from the field observations suggest that cut-bank retreat also significantly contributes to internal sediment redistribution.

    The explanations have revealed, that a small vehicle has certain handicaps from the beginning. The disadvantages are on the one hand the smaller mass, when it comes to a frontal collision with larger vehicles and on the other hand the smaller dimensions, which makes the realisation of deformation zones more difficult. Based on calculations it has been proved, that these difficulties can be solved. The effects of a frontal collision can be reduced by airbags, combined with soft safety belts and knee protectors. The front structure should have a rectangular force/way characteristic and show as far as possible a plastic reaction. A side collision requires considerable protective measures at the design of the padding and the door. Small vehicles can be safe vehicles. However, they are not light vehicles, since they must be designed according to strong structural forces. Due to the high expenditure for the structural and protective system, these vehicles are no longer very cost-effective. (orig.) [Deutsch] In den Ausfuehrungen wurde gezeigt, dass ein kleines Fahrzeug von vornherein mit gewissen Handikaps versehen ist. Diese Nachteile liegen einerseits in der kleineren Masse, wenn es frontal mit grossen Fahrzeugen kollidiert und andererseits in den kleineren Abmessungen, die die Bereitstellung von Deformationszonen erschwert. Auf der Basis rechnerischer Studien konnte aber auch gezeigt werden, dass die Schwierigkeiten nicht von vornherein als unloesbar anzusehen sind. Der Frontalstoss kann u.a. durch Airbags, verbunden mit einem weichen Gurt sowie einem Kniepolster ertraeglich gestaltet werden. Die Frontstruktur selbst sollte eine rechteckfoermige Kraft/Wegkennung haben und sich so weit wie moeglich plastisch verhalten. Der Seitenstoss erfordert vom kleinen Fahrzeug einigen Aufwand bei der Gestaltung der Polsterung und der Tuer. Kleine Fahrzeuge koennen sichere Fahrzeuge sein. Es sind keine leichten Fahrzeuge, da sie fuer erhoehte Strukturkraefte ausgelegt sein muessen

    2012-01-01

    Full Text Available This paper presents an analysis of the semantics of bird denominations in Mari: an attempt is made to define the factors, or features, motivating bird denominations. Analysis is based on a set of words of inner origin that are part of the corpus of bird names compiled by the author. The results show that the ornithonomy of the Mari language, created over centuries, constitutes a well-shaped system. It reflects a variety of features associated with the appearance, way of life of the birds, sounds they produce, etc. Many bird terms reflect features of appearance. It is interesting to note that the names of birds not seen for some reason may relate to the characteristics of the birds’ voices. In some cases, terms are based on a combination of features.In dialects, different names for same birds may occur, as observed in the sources.

  18. Revisiting Mary Daly: Towards a quadripartite theological and philosophical paradigm

    Directory of Open Access Journals (Sweden)

    Hannelie Wood

    2015-06-01

    Full Text Available I was a tenderfoot in feminist discourse when I started my research on patriarchy, feminism, and Mary Daly. In my thesis, one aspect I engaged was Daly’s battle with gender issues in Christian theology. From the beginning I was troubled by Mary Daly’s views on God, men, and women in her discourse on Christianity. Daly undoubtedly contributed to the discussion on gender issues in the Christian faith, but her focus on androcentrism and her interpretations of Scripture led her to abandon the Christian faith. Mary Daly has written extensively on patriarchy as it is found in religion – particularly in the Christian faith – and how it filters through society. In her critique of patriarchy she set her course to dismantle the facade of a patriarchal and misogynistic God as the root of patriarchy. Daly did not see any positive qualities of the Christian faith and completely rejected other interpretations of a God whose person embraces both male and female qualities. Against this background I will evaluate Daly’s post-Christian feminist theological and philosophical paradigm. I propose that Daly has a quadripartite theological and philosophical paradigm wherein there are four main players. The ‘Who is who’ in Daly’s quadripartite patriarchal theological and philosophical paradigm are the patriarchal male, the patriarchal female, the patriarchal God and the biophilic woman.

  19. A different voice: Mary Hays's the Memoirs of Emma Courtney.

    Science.gov (United States)

    2001-01-01

    Mary Hays wrote in the decade of the 1790s, a period of intense creative flowering in England. Writing in a period enshrined to the works of the canonical Wordsworth and Coleridge, Hays explored through her Jacobinical novel, The Memoirs of Emma Courtney, the contentious relationship between self and society. Like other Jacobin women writers - Elizabeth Inchbald, Charlotte Smith and Mary Wollstonecraft - Mary Hays too used her novel to explode the insidious connection between education and gender construction. Emma Courtney is a landmark novel that wrestles with the paradigm of decorum and propriety which disallows women from voicing their aspirations. In the process, Hays merges the plots of the domestic novel of courtship and love with the novel of ideas to create a searing portrait of women's intellectual confinement and psychic dissonance in a society that only projects them in terms of their gender construction. Memoirs of Emma Courtney is a remarkable novel in its depiction of the emotional imbalance created by thwarted desire: intellectual and sexual.

  20. The Pasteurization of Marie Curie: A (meta)biographical experiment.

    Wirtén, Eva Hemmungs

    2015-08-01

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

  1. Trans-Colonial Collaboration and Slave Narrative: Mary Prince Revisited

    Directory of Open Access Journals (Sweden)

    Michelle Gadpaille

    2011-10-01

    Full Text Available In 1831 in London, two formidable women met: Mary Prince, an ex-slave from Bermuda, who had crossed the Atlantic to a qualified freedom, and Susanna Strickland, an English writer. The narrative that emerged from this meeting was The History of Mary Prince, which played a role in the fight for slave emancipation in the British Empire. Prince disappeared once the battle was won, while Strickland emigrated to Upper Canada and, as Susanna Moodie, became an often quoted 19th century Canadian writer. Prince dictated, Strickland copied, and the whole was lightly edited by Thomas Pringle, the anti-slavery publisher at whose house the meeting took place. This is the standard account. In contesting this version, the paper aims to reinstate Moodie as co-creator of the collaborative Mary Prince text by considering multiple accounts of the meeting with Prince and to place the work in the context of Moodie’s pre- and post-emigration oeuvre on both sides of the Atlantic.

  4. Chaos on the interval

    Ruette, Sylvie

    2017-01-01

    The aim of this book is to survey the relations between the various kinds of chaos and related notions for continuous interval maps from a topological point of view. The papers on this topic are numerous and widely scattered in the literature; some of them are little known, difficult to find, or originally published in Russian, Ukrainian, or Chinese. Dynamical systems given by the iteration of a continuous map on an interval have been broadly studied because they are simple but nevertheless exhibit complex behaviors. They also allow numerical simulations, which enabled the discovery of some chaotic phenomena. Moreover, the "most interesting" part of some higher-dimensional systems can be of lower dimension, which allows, in some cases, boiling it down to systems in dimension one. Some of the more recent developments such as distributional chaos, the relation between entropy and Li-Yorke chaos, sequence entropy, and maps with infinitely many branches are presented in book form for the first time. The author gi...

The most frequent sterilization procedures include postpartum tubal ligation, laparoscopic tubal disruption or salpingectomy, and hysteroscopic tubal occlusion. The informed consent process for sterilization is crucial and requires shared decision-making between the patient and the health care provider. Counseling should include the specific risks and benefits of the specific surgical approaches. Additionally, women should be counseled on the alternatives to sterilization, including intrauterine contraceptives and subdermal contraceptive implants. Complications, including unplanned pregnancy after successful female sterilization, are rare. The objectives of this Clinical Expert Series are to describe the epidemiology of female sterilization, access to postpartum sterilization, advances in interval sterilization techniques, and clinical considerations in caring for women requesting sterilization.

    Rapoport, Diego Lucio

    2013-01-01

    We present a unified principle for science that surmounts dualism, in terms of torsion fields and the non-orientable surfaces, notably the Klein Bottle and its logic, the Möbius strip and the projective plane. We apply it to the complex numbers and cosmology, to non-linear systems integrating the issue of hyperbolic divergences with the change of orientability, to the biomechanics of vision and the mammal heart, to the morphogenesis of crustal shapes on Earth in connection to the wavefronts of gravitation, elasticity and electromagnetism, to pattern recognition of artificial images and visual recognition, to neurology and the topographic maps of the sensorium, to perception, in particular of music. We develop it in terms of the fundamental 2:1 resonance inherent to the Möbius strip and the Klein Bottle, the minimal surfaces representation of the wavefronts, and the non-dual Klein Bottle logic inherent to pattern recognition, to the harmonic functions and vector fields that lay at the basis of geophysics and physics at large. We discuss the relation between the topographic maps of the sensorium, and the issue of turning inside-out of the visual world as a general principle for cognition, topological chemistry, cell biology and biological morphogenesis in particular in embryology

  11. SPECT in the Kleine-Levin syndrome, a possible diagnostic and prognostic aid?

    Directory of Open Access Journals (Sweden)

    Patrick Emanuel Vigren

    2014-09-01

    Full Text Available INTRODUCTION: Kleine-Levin syndrome (KLS is a rare syndrome of periodic hypersomnia and behavioral and cognitive symptoms based on clinical criteria. In the setting of differential diagnosis of hypersomnia disorders, an objective diagnostic aid is desirable. A promising modality is single photon emission computed tomography (SPECT. As intraepisodal investigations are difficult to perform, an interepisodal investigation would be very helpful. Another aim of the study was to correlate SPECT findings to prognosis. METHODS AND MATERIAL: 24 KLS-patients were categorized as severe or non-severe based on clinical characteristics. The clinical characteristics were analyzed in relation to SPECT-examinations performed between hypersomnia periods (interepisodal or after remission, as a clinical routine investigation.RESULTS: 48% of the KLS-patients have hypoperfusion in the temporal or fronto-temporal regions. In patients that have undergone remission, 56% show that pattern. There were no specific findings related to prognosis.DISCUSSION/CONCLUSION: SPECT might be a diagnostic aid, in a setting of hypersomnia experience. With a sensitivity of 48%, interepisodal SPECT alone cannot be used for diagnosing KLS.

  12. Kaluza-Klein gluon + jets associated production at the Large Hadron Collider

    Iyer, A.M.; Manglani, N.; Sridhar, K.

    2016-08-10

    The Kaluza-Klein excitations of gluons offer the exciting possibility of probing bulk Randall-Sundrum (RS) models. In these bulk models either a custodial symmetry or a deformation of the metric away from AdS is invoked in order to deal with electroweak precision tests. Addressing both these models, we suggest a new channel in which to study the production of KK-gluons ($g_{KK}$): one where it is produced in association with one or more hard jets. The cross-section for the $g_{KK}+$ jets channel is significant because of several contributing sub-processes. In particular, the 1-jet and the 2-jet associated processes are important because at these orders in QCD the $qg$ and the $gg$ initial states respectively come into play. We have performed a hadron-level simulation of the signal and present strategies to effectively extract the signal from what could potentially be a huge background. We present results for the kinematic reach of the LHC Run-II for different $g_{KK}$ masses in bulk-RS models.

  13. Relativistic particle in a box: Klein-Gordon versus Dirac equations

    Science.gov (United States)

    Alberto, Pedro; Das, Saurya; Vagenas, Elias C.

    2018-03-01

    The problem of a particle in a box is probably the simplest problem in quantum mechanics which allows for significant insight into the nature of quantum systems and thus is a cornerstone in the teaching of quantum mechanics. In relativistic quantum mechanics this problem allows also to highlight the implications of special relativity for quantum physics, namely the effect that spin has on the quantised energy spectra. To illustrate this point, we solve the problem of a spin zero relativistic particle in a one- and three-dimensional box using the Klein-Gordon equation in the Feshbach-Villars formalism. We compare the solutions and the energy spectra obtained with the corresponding ones from the Dirac equation for a spin one-half relativistic particle. We note the similarities and differences, in particular the spin effects in the relativistic energy spectrum. As expected, the non-relativistic limit is the same for both kinds of particles, since, for a particle in a box, the spin contribution to the energy is a relativistic effect.

  15. Observability of gamma-ray spectral feature from Kaluza-Klein dark matter

    Science.gov (United States)

    Tsuchida, Satoshi; Mori, Masaki

    2017-01-01

    The theory of universal extra dimensions involves Kaluza-Klein (KK) particles. The lightest KK particle (LKP) is one of the good candidates for cold dark matter. Annihilation of LKP dark matter in the Galactic halo produces high-energy gamma-rays. The gamma-ray spectrum shows a characteristic peak structure around the LKP mass. This paper investigates the observability of this peak structure by present and near-future detectors taking account of their energy resolution, and calculates the expected count spectrum of the gamma-ray signal. Then, the maximum likelihood analysis is employed to judge whether the count spectrum contains the LKP signal. In the case where the signal is not detected, we set some constraints on the boost factor which is a product of the annihilation cross section relative to the thermal one and an uncertain factor dependent on the substructure of the LKP distribution in the Galactic halo. The constraints can be regarded as comparable with the results of analysis based on the HESS data. The observational data for the TeV or higher energy region are still limited, and the possible LKP signal is not conclusive. Thus, we expect near-future missions with better sensitivity will clarify whether the LKP dark matter should exist or not.

  16. Gravitational Kaluza-Klein modes in the string-cigar braneworld

    Veras, D. F. S.; Silva, J. E. G.; Cruz, W. T.; Almeida, C. A. S.

    2015-03-01

    In this work we analyze the properties of the gravitational Kaluza-Klein (KK) modes in two stringlike braneworlds, the thin Gherghetta-Shaposhnikov (GS) model and the thick string-cigar model. The string-cigar model is a smooth generalization of the GS model that undergoes a Ricci geometrical flow. We find a new massless mode in both models satisfying the respective Schrödinger equations. By means of a numerical analysis, we obtain the complete graviton spectrum and its respective eigenfunctions. The KK spectrum exhibits the usual linear regime for large discrete index n and we find a new decreasing regime for small n . Moreover, there is an asymmetric mass gap between the massless mode and the massive KK tower. The mass gap in the GS model is bigger than in the string-cigar model. In addition, the mass gap remains invariant upon the geometrical flow. It turns out that in the string-cigar model the brane structure smoothes and amplifies the KK modes near the brane core. The presence of a potential well in the string-cigar scenario allows the existence of resonant massive gravitons for small masses.

    2012-01-01

    A new phenanthrenequinone, 5-hydroxy-2,3-dimethoxy-1,4-phenanthrenequinone (1), was isolated along with a known 9,10-dihydrophenanthrenequinone, ephemeranthoquinone B (2) from an MeOH extract of Odontioda Marie Noel 'Velano' through bioassay-guided fractionation. Their structures were elucidated by spectroscopic analysis, and the compounds were tested for in vitro cytotoxic activity. The compounds showed slightly higher cytotoxicity in human oral squamous cell carcinoma and leukemic cell lines as compared with human oral normal cells. The results suggest that apoptosis may not be involved in the cytotoxicity induction.

    This biography traces the life and work of Mary Fairfax Somerville, whose extraordinary mathematical talent only came to light through fortuitous circumstances. Barely taught to read and write as a child, all the science she learned and mastered was self taught. In this delightful narrative the author takes up the challenge of discovering how Somerville came to be one of the most outstanding British women scientists and, furthermore, a popular writer. Particular attention is paid to the gender aspects of Somerville's success in what was, to put it mildly, a predominantly male domain.

  1. Leaching and solvent extraction at Mary Kathleen Uranium Ltd

    International Nuclear Information System (INIS)

    Richmond, G.D.

    1978-01-01

    Mary Kathleen Uranium Ltd. recommenced operations in early 1976 following a twelve year period of care and maintenance. Several sections of the plant were modified or completely changed for the second operation. The most important change was the replacement of ion exchange with solvent extraction as the means of purifying and upgrading uranium rich solutions. Most of the problems experienced in the solvent extraction system originate from the leach liquor which has a strong tendency to form stable emulsions. This has been countered by some careful control of leaching conditions and by closer observation of operations in the solvent extraction area. Most problems have now been resolved and plant recoveries are quite satisfactory

    This article presents a new interpretation of Kierkegaard’s Fear and Trembling that focuses on the comparison between Abraham and Mary in this text. The readings of Genesis 22 and Luke 1 offered by Kierkegaard’s pseudonym Johannes de silentio develop a poetic reconstruction of the biblical characters by imagining their inwardness. In both cases, the inwardness of faith is depicted as ‘humble courage’, a virtue that involves silence and listening. The article argues that it is this virtue, and...

    This study determines the impact of symptoms associated with Charcot-Marie-Tooth disease on quality-of-life. Charcot-Marie-Tooth patients in the Inherited Neuropathies Consortium Rare Diseases Clinical Research Network Contact Registry were surveyed. The survey inquired about 214 symptoms and 20 themes previously identified as important to Charcot-Marie-Tooth patients through patient interviews. Symptom population impact was calculated as the prevalence multiplied by the relative importance of each symptom identified. Prevalence and symptom impact were analyzed by age, symptom duration, gender, Charcot-Marie-Tooth type, and employment status. 407 participants returned the survey, identifying foot and ankle weakness (99.7%) and impaired balance (98.6%) as the most prevalent themes. Foot and ankle weakness and limitations with mobility were the themes with the highest impact. Both symptom prevalence and impact gradually increased with age and symptom duration. Several themes were more prevalent in women with Charcot-Marie-Tooth, including activity limitations, pain, fatigue, hip-thigh weakness, and gastrointestinal issues. All of the themes, except emotional or body image issues, were more prevalent among unemployed individuals. There were minimal differences in symptom prevalence between Charcot-Marie-Tooth types. There are multiple symptoms that impact Charcot-Marie-Tooth quality-of-life in adults. These symptoms have different levels of importance, are readily recognized by patients, and represent critical areas of Charcot-Marie-Tooth health. Copyright © 2014 Elsevier B.V.

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

    Full Text Available A case of Kleine-Levin syndrome, with chronic severe periodic hypersomnia is described in a 17-year-old female. The first episode started when she was 15 years old. The episodes were characterized by periodic hypersomnia accompanied by hyperphagia, lasting 5 days, and repeating at 28 to 60 day intervals. The severity of hypersomnia prevented her from attending school activities. Outside the hypersomnia periods, she was asymptomatic. EEG, brain computerized tomography and brain nuclear magnetic resonance were normal; all-night polysomnography, Multiple Sleep Latency Test (MSLT and Epworth Sleepiness Scale (ESS were within normal limits. During the period of hypersomnolence, polysomnography showed short sleep latency and short REM latency. MSLT mean sleep latency was 1.8 min; and REM period was present in one subtest; the ESS was markedly elevated.Relata-se o caso de paciente com s��ndrome de Kleine-Levin, de 17 anos de idade, sexo feminino, com períodos de hipersônia recorrente, severa e crônica.

    Full Text Available Mary Delany (1700-1788 is particularly famous for her paper-cuttings or ‘mosaicks’ based on botanical subjects. A very lively woman of fashion, she was close to Queen Charlotte and one of the Bluestocking Ladies. She left a vivid portrait of life and society in eighteenth century England and Ireland in the six volumes of her Autobiography and Letters, edited in 1861 by her descendant Lady Llanover. Her autobiography is made up of 18 letters sent to her most intimate friend, Margaret Cavendish, Duchess of Portland. The first letter is dated 1740, but in this, as in the following ones, Mrs. Delany narrates her past life to her friend, starting from the early years of her life, describing her unhappy marriage, financial difficulties as a widow, and family relationships. Along with these ‘autobiographical’ letters, other letters written by her to her sister Ann are introduced, which date to the periods of life Mrs. Delany is dealing with. The aim of this paper is to focus on the textual, linguistic and content differences between the two letter types, and analyse how the identity of Mary Delany is differently constructed and perceived in the explicit autobiographical letters addressed to the Duchess of Portland, and the ones written to her sister. 

  3. Taking Stock: Marie Nimier’s Textual Cabinet of Curiosities

    Full Text Available In many life-writing projects, the seemingly innocuous description of heteroclite objects and how those objects are stored and recalled in fact plays an important role in demonstrating their importance to the process of memory work. At once the lingering traces of one’s past and also an aggregation of stories evoked by an examination of them, these curios focus attention on the relationship between the individual and the storage of memories. This article will focus on certain collectibles, collections and collectors that appear throughout the fictional, autobiographical and autofictional world that Marie Nimier has scripted to date. This textual cabinet of curiosities and the act of collecting more generally serve as a trope to connect memory with materiality, despite the numerous narrative voices that Nimier assumes—voices that move from a first-person “Marie Nimier” to an unnamed, although clearly identifiable first-person and even float between genders. Despite this nominal and narrational fluidity, objects function to guarantee recognition, both for the reader, and, especially, for the author herself. What is at stake in this intertextual assemblage of objects is not only the roles that they play in allowing the narrator to revisit past traumas and loss, but also in connecting the author’s presence to other, more fictionalized voices that above all signify the primacy of life-writing in her corpus.

    The ability to quickly detect transient sources in optical images and trigger multi-wavelength follow up is key for the discovery of fast transients. These include events rare and difficult to detect such as kilonovae, supernova shock breakout, and `orphan' Gamma-ray Burst afterglows. We present the Mary pipeline, a (mostly) automated tool to discover transients during high-cadenced observations with the Dark Energy Camera at Cerro Tololo Inter-American Observatory (CTIO). The observations are part of the `Deeper Wider Faster' programme, a multi-facility, multi-wavelength programme designed to discover fast transients, including counterparts to Fast Radio Bursts and gravitational waves. Our tests of the Mary pipeline on Dark Energy Camera images return a false positive rate of 2.2% and a missed fraction of 3.4% obtained in less than 2 min, which proves the pipeline to be suitable for rapid and high-quality transient searches. The pipeline can be adapted to search for transients in data obtained with imagers other than Dark Energy Camera.

    Full Text Available Dans La Reine du silence, Marie Nimier se confronte à la figure de son père, l’écrivain Roger Nimier, mort lorsqu’elle avait cinq ans. Elle y montre le poids qui pèse sur l’enfant d’écrivain, mais aussi celui de l’héritage du secret familial et de l’injonction au silence. La difficulté de l’élaboration de son récit de filiation se révèle dans les constants recommencements et reformulations, qui constituent la marque de la tension angoissante entre l’obligation de dire et celle de taire. In La Reine du silence, Marie Nimier confronts her father’s memory – the writer Roger Nimier, who died when she was five years old. The novel describes the burden of being a writer’s child, along with that of inheriting family secrets and submitting to a code of silence. The difficulty of recounting her relationship with her late father is evidenced by the narrator’s numerous “false starts” and her constant rewritings. The hesitant nature of the narration captures an anguish born of two irreconcilable obligations : the need to put things into words and the pressure to remain silent.

    Full Text Available Charcot-Marie-Tooth hereditary motor and sensory neuropathy refers to a group of disorders characterized by a chronic motor and sensory polyneuropathy. Typical cases have distal muscle weakness and peroneal atrophy often associated with mild to moderate sensory loss, depressed tendon reflexes, and pes cavus. Hereditary neuropathies are categorized by mode of inheritance and chromosomal locus. The diagnosis is based on family history, characteristic findings on physical examination, EMG, nerve conduction velocity testing, and occasionally on nerve biopsy. The disorder shows allelic and non-allelic genetic heterogeneity, thus mutations of different genes leading to the same clinical features. Also, different mutations of the same gene may lead to different phenotypes. Molecular genetic testing is available in clinical laboratories for diagnosis of 7 subtypes of the disease. Genetic counseling and risk assessment depend on the inheritance. We present two cases with Charcot-Marie-Tooth type 1 and type 2 respectively. There is no cure for the disorder, although physical therapy and moderate activity are often recommended to maintain muscle strength and endurance.

    In this study we evaluated fracture risk in patients with Charcot-Marie-Tooth (CMT) disease. We conducted a retrospective cohort study using the UK Clinical Practice Research Datalink (1987-2012). Each patient with CMT disease was matched with up to 6 patients without a history of CMT disease. The outcome measure was fractures. The risk of non-osteoporotic fracture was statistically significantly increased [adjusted hazard ratio (AHR) 1.47, 95% confidence interval (CI) 1.01-2.14], whereas risk of any and osteoporotic fracture did not reach statistical significance compared with control patients [AHR 1.31 (95% CI 0.98-1.74) and AHR 1.10 (95% CI 0.69-1.74), respectively]. CMT patients have a 1.5-fold increased risk for non-osteoporotic fracture. Studies with larger numbers of CMT patients and with additional data on CMT subtype, bone mineral density, and functional status should be performed to confirm a true association between CMT and an increased risk of fracture. © 2014 Wiley Periodicals, Inc.

  9. Static wormholes on the brane inspired by Kaluza-Klein gravity

    Leon, J. Ponce de, E-mail: jpdel@ltp.upr.clu.edu [Laboratory of Theoretical Physics, Department of Physics, University of Puerto Rico, P.O. Box 23343, San Juan, PR 00931 (United States)

    2009-11-01

    We use static solutions of 5-dimensional Kaluza-Klein gravity to generate several classes of static, spherically symmetric spacetimes which are analytic solutions to the equation {sup (4)}R = 0, where {sup (4)}R is the four-dimensional Ricci scalar. In the Randall and Sundrum scenario they can be interpreted as vacuum solutions on the brane. The solutions contain the Schwarzschild black hole, and generate new families of traversable Lorenzian wormholes as well as nakedly singular spacetimes. They generalize a number of previously known solutions in the literature, e.g., the temporal and spatial Schwarzschild solutions of braneworld theory as well as the class of self-dual Lorenzian wormholes. A major departure of our solutions from Lorenzian wormholes a la Morris and Thorne is that, for certain values of the parameters of the solutions, they contain three spherical surfaces (instead of one) which are extremal and have finite area. Two of them have the same size, meet the ''flare-out'' requirements, and show the typical violation of the energy conditions that characterizes a wormhole throat. The other extremal sphere is ''flaring-in'' in the sense that its sectional area is a local maximum and the weak, null and dominant energy conditions are satisfied in its neighborhood. After bouncing back at this second surface a traveler crosses into another space which is the double of the one she/he started in. Another interesting feature is that the size of the throat can be less than the Schwarzschild radius 2M, which no longer defines the horizon, i.e., to a distant observer a particle or light falling down crosses the Schwarzschild radius in a finite time.

  10. Nuclear spin Hall and Klein tunneling effects during oxidation with electric and magnetic field inductions in graphene.

    The recent observation of the explosive oxidation of graphene with enhancement for decreasing temperature and the requirements for synchronizing oxidants for collective oxidation-reduction (redox) reactions presented a chemical scenario for the thermal harvesting by the magnetic spin Hall Effect. More experimental data are presented to demonstrate such spin Hall Effect by determining the influence of spins of so-called spectator fermionic cations. Furthermore, the so-called spectator bosonic cations are discovered to cause a Klein tunneling effect during the redox reaction of graphene. The Na(+) and K(+), fermionic cations and the Mg(2+) and Ca(2+), bosonic cations were observed and compared under a variety of experimental conditions: adiabatic reactions with initial temperatures (18-22 °C); reactions toward infinite dilution; isothermal reactions under nonadiabatic conditions at low temperature of 18 °C; reactions under paramagnetic O(2) or diamagnetic N(2) atmospheres of different permeabilities; reactions in applied and no applied external magnetic field; and reactions toward excess concentrations of common and uncommon Na(+) and Mg(2+) cations. The observed reaction kinetics and dynamics under these various, diverse conditions are consistent with the spin Hall mechanism, energy harvesting and short time violation of Second Law of Thermodynamics for redox reactions of graphene by the Na(+)K(+) mixture and are consistent with the Klein tunnel mechanism for the redox reactions of graphene by the Mg(2+)Ca(2+) mixture. Mixed spin Hall and Klein tunnel mechanisms are discovered to slow and modulate explosive redox reactions. Such spin Hall Effect also gives explanation of recent tunneling of electrons through boron nitride.

    2009-10-01

    The new Appendix A of the European Convention for the Protection of Vertebrate Animals Used for Experimental and Other Scientific Purposes, which gives guidelines for accommodation and care of animals and was approved on June 15, 2006, was the main reason the authors decided to investigate the origins of the regulations of animal experiments. Although one might assume that the regulation had its origin in the United Nations conventions, the truth is that its origins are a hundred years old. The authors present a case of the nineteenth-century vivisection controversy brought about by the publication of the Handbook for the Physiological Laboratory in 1873, in which John Burdon-Sanderson, Emanuel Edward Klein, Michael Foster, and Thomas Lauder Brunton described a series of vivisection experiments they performed on animals for research purposes. It was the first case of vivisection to be examined, processed, and condemned for inhuman behavior toward animals before an official body, leading to enactment of the Cruelty to Animals Act in 1876. The case reveals a specific ethos of science in the second half of the nineteenth century, which was characterized by a deep commitment of scientists to the scientific enterprise and their strong belief that science could solve social problems, combined with an overt insensitivity to the suffering of experimental animals. The central figure in the case was Emanuel Edward Klein, a disciple of the Central European medical tradition (Vienna Medical School) and a direct follower of the experimental school of Brücke, Stricker, Magendie, and Bernard. Because of his undisguised attitudes and opinions on the use of vivisection, Klein became a paradigm of the new scientific identity, strongly influencing the stereotypic image of a scientist, and polarizing the public opinion on vivisection in England in the nineteenth century and for some considerable time afterward.

    2001-01-01

    While thorough investigation of many aspects of contemporary scientific developments and Mary Shelley's personal history have provided illuminating contexts for the study of Frankenstein, the activities of the Royal Humane Society, and other bodies and individuals who pioneered and publicized resuscitation techniques, have been comparatively neglected. Here we find a richly documented, highly conspicuous area of scientific endeavour, which generated much excitement in life and literature from the last quarter of the eighteenth century onwards. There are three major points of contact with Frankenstein: Victor Frankenstein's revival of dead tissue to make his creature; the frequent occurrences of unconsciousness and asphyxia, both in the novel and in Mary Shelley's family during the period leading up to its composition, and the widely differing degrees of competence and success with which they are treated; and the possibility that resuscitative techniques were used to revive Mary Shelley's mother, Mary Wollstonecraft, after a suicide attempt. The impact on Frankenstein of Mary Shelley's lifelong distress at the role she played in bringing about her mother's death in childbirth has been thoroughly canvassed by other critics, notably Anne Mellor, but the thought that Mary Shelley, who was herself conceived after her mother's second suicide attempt, might be, in a sense, a child of the dead adds a further turn to the Gothic screw. This study traces a hitherto unexplored intersection between Mary Shelley's first novel and her family history, as well as showing how it launches a formidable attack on the shady ethics and inconsiderate arrogance of some early resuscitators.

    In this paper, we develop a general theory on the coverage probability of random intervals defined in terms of discrete random variables with continuous parameter spaces. The theory shows that the minimum coverage probabilities of random intervals with respect to corresponding parameters are achieved at discrete finite sets and that the coverage probabilities are continuous and unimodal when parameters are varying in between interval endpoints. The theory applies to common important discrete ...

    Science.gov (United States)

    Hafez, M. G.; Alam, Md. Nur; Akbar, M. Ali

    The novel (G‧/G)-expansion method is one of the powerful methods that appeared in recent times for establishing exact traveling wave solutions of nonlinear partial differential equations. Exact traveling wave solutions in terms of hyperbolic, trigonometric and rational functions to the cubic nonlinear Klein-Gordon equation via this method are obtained in this article. The efficiency of this method for finding exact solutions and traveling wave solutions has been demonstrated. It is shown that the novel (G‧/G)-expansion method is a simple and valuable mathematical tool for solving nonlinear evolution equations (NLEEs) in applied mathematics, mathematical physics and engineering.

    A newly designed, large-aperture and high-resolution bent-crystal spectrometer has been used to observe high-intensity sources of pionic x rays. The pionic x-ray source was a target of natural titanium which was placed adjacent to a copper pion-production target in the external beam of the Nevis synchrocyclotron. The energy difference between the 5g → 4f and 5f → 4d transitions in pionic titanium was measured to be 87.6 +- 1.8 eV. Comparison with the prediction of the Klein-Gordon equation is made

    A five dimensional Kaluza-Klein space-time is considered in the frame work of a scalar-tensor theory proposed by Saez and Ballester (Phys. Lett. A 113, 467, 1985) when the source for energy momentum tensor is a bulk viscous fluid containing one dimensional strings. A barotropic equation of state for the pressure and density is assumed to get a determinate solution of the field equations. Also the bulk viscous pressure is assumed to be proportional to the energy density. The physical and kinematical properties of the model are also discussed.

    Full Text Available We study thermodynamical properties of static dyonic AdS black holes in four-dimensional ω-deformed Kaluza–Klein gauged supergravity theory, and find that the differential first law requires a modification via introducing a new pair of thermodynamical conjugate variables (X,Y. To ensure such a modification, we then apply the quasi-local ADT formalism developed in Kim et al. (2013 [20] to calculate the quasi-local conserved charge and identify that the new pair is precisely the one previously introduced to modify the differential form of the first law.

    2015-12-11

    Charcot-Marie-Tooth disease (CMT) comprises a large group of different forms of hereditary motor and sensory neuropathy. The molecular basis of several CMT subtypes has been clarified during the last 20 years. Since slowly progressive muscle weakness and sensory disturbances are the main features of these syndromes, treatments aim to improve motor impairment and sensory disturbances to improve abilities. Pharmacological treatment trials in CMT are rare. This review was derived from a Cochrane review, Treatment for Charcot Marie Tooth disease, which will be updated via this review and a forthcoming title, Treatments other than ascorbic acid for Charcot-Marie-Tooth disease. To assess the effects of ascorbic acid (vitamin C) treatment for CMT. On 21 September 2015, we searched the Cochrane Neuromuscular Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and LILACS for randomised controlled trials (RCTs) of treatment for CMT. We also checked clinical trials registries for ongoing studies. We included RCTs and quasi-RCTs of any ascorbic acid treatment for people with CMT. Where a study aimed to evaluate the treatment of general neuromuscular symptoms of people with peripheral neuropathy including CMT, we included the study if we were able to identify the effect of treatment in the CMT group. We did not include observational studies or case reports of ascorbic acid treatment in people with CMT. Two review authors (BG and JB) independently extracted the data and assessed study quality. Six RCTs compared the effect of oral ascorbic acid (1 to 4 grams) and placebo treatment in CMT1A. In five trials involving adults with CMT1A, a total of 622 participants received ascorbic acid or placebo. Trials were largely at low risk of bias. There is high-quality evidence that ascorbic acid does not improve the course of CMT1A in adults as measured by the CMT neuropathy score (0 to 36 scale) at 12 months (mean difference (MD) -0.37; 95

    Full Text Available The Shannon interval entropy function as a useful dynamic measure of uncertainty for two sided truncated random variables has been proposed in the literature of reliability. In this paper, we show that interval entropy can uniquely determine the distribution function. Furthermore, we propose a measure of discrepancy between two lifetime distributions at the interval of time in base of Kullback-Leibler discrimination information. We study various properties of this measure, including its connection with residual and past measures of discrepancy and interval entropy, and we obtain its upper and lower bounds.

    2012-07-01

    There have been suggestions from previous studies that patients with Charcot-Marie-Tooth disease (CMT) have weaker dominant hand muscles. Since all studies to date have included a heterogeneous group of CMT patients we decided to analyse hand strength in 43 patients with CMT1X. We recorded handedness and the MRC scores for the first dorsal interosseous and abductor pollicis brevis muscles, median and ulnar nerve compound motor action potentials and conduction velocities in dominant and non-dominant hands. Twenty-two CMT1X patients (51%) had a weaker dominant hand; none had a stronger dominant hand. Mean MRC scores were significantly higher for first dorsal interosseous and abductor pollicis brevis in non-dominant hands compared to dominant hands. Median nerve compound motor action potentials were significantly reduced in dominant compared to non-dominant hands. We conclude that the dominant hand is weaker than the non-dominant hand in patients with CMT1X.

  5. The lives of Mary Foote: painter and Jungian.

    Science.gov (United States)

    Trousdell, Richard

    2016-11-01

    Mary Foote (1872-1968) was a successful early twentieth century American artist who suddenly closed her New York studio in 1926 to go to Zurich to study with Jung. There she joined his 'Interpretation of Visions' seminars (1930-1934), which she recorded and edited. This work won Jung's praise and his friendship, but all too often Foote was seen merely as a secretary or background figure. Deirdre Bair's biography of Jung suggested that Foote's life and work deserved fuller study, if only to rebalance our view of Jung's early women followers. This paper takes up that work to ask how Foote's early life and career led to her important work in preserving and describing Jung's earliest attempts to apply his theories to clinical practice. © 2016, The Society of Analytical Psychology.

    2014-01-01

    Full Text Available In her 2009 Goncourt-Prize-winning novel, Trois femmes puissantes ( Three Strong Women, Marie Ndiaye experiments with a polyphonic, semi-fantastical rendering of identity-threatening displacements experienced by three women from different socio-geographic backgrounds. In a brief "Counterpoint" at the end of each of the novel's three sections--a narrative take on the musical technique employed by Ndiaye to introduce new focalizations and unexpected turns of events that complicate interpretations of the characters' behavior--each of the women is perceived as metamorphosed into a bird or a birdlike persona. This essay examines the innovative embedding of the shape-shifts in Trois femmes puissantes in both harrowing socio-political realities and the ambiguities of the fantastic and superstition to convey the dehumanizing, unequal power relations governing contemporary women's migration struggles.

    Introduction This study aims to assess the frequency, location, severity, duration, and fluctuation over time of muscle cramps in Charcot Marie Tooth Disease (CMT). Methods Inherited Neuropathies Consortium Contact Registry participants recorded the occurrence and characteristics of muscle cramps using an 11-question survey administered three times over 8-weeks. Results One hundred and ten adult patients with CMT completed the survey. Weekly cramp frequency was 9.3 (SD 12.3) and 23% had daily muscle cramps. Twenty-two percent reported a significant impact on quality of life. Over 8-weeks, the daily frequency and severity of muscle cramps did not change significantly. Conclusions Patients with CMT have muscle cramps that vary little over an eight-week period, and may interfere with quality of life. These data may be useful in the planning of clinical trials of agents to treat adults with CMT-associated muscle cramps. PMID:25042364

    Full Text Available By means of literature research, this article seeks to analyze the historical time of Queen Elisabeth regarding, in particular, the clash with the Scottish queen Mary Stuart. We selected - as cutouts for analysis - conflicts, paradoxes and tensions that underlie the search for legality and legitimacy. In the eternal struggle for power, the characters are faced with political life and death, the rise and decay, the glory and failure, which are inevitable and constitutive stages of the game of thrones. In this study, under a realistic bias, we discuss the triad - conquest maintenance and fall from power - about the shocking and devastating meaning of politic as tragedy in the pursuit of order and harmony in the face of chaos and instability is always present.

  9. Marie Curie: the Curie Institute in Senegal to Nuclear Physics

    Science.gov (United States)

    Gueye, Paul

    Sub-Saharan Africa is not a place where one will look first when radioactivity or nuclear physics is mentioned. Conducting forefront research at the international stage at US national facilities such as the Thomas Jefferson National Accelerator Facility in Virginia or the National Superconducting Cyclotron Facility/Facility for Rare Isotope Beams in Michigan does not point to Historically Black Colleges either. The two are actually intrinsically connected as my personal journey from my early exposure to radiation at the Curie Institute at the LeDantec Hospital in Senegal lead me to Hampton University. The former, through one of my uncles, catapulted me into a nuclear physics PhD while the latter houses the only nuclear physics program at an HBCU to date that has established itself as one of the premier programs in the nation. This talk will review the impact of Marie Curie in my life as a nuclear physicist.

It is considered to be congenital (genetic cardiomyopathy. It is usually associated with genetic disorders and that could explain the genetic pathogenesis of the non-compaction cardiomyopathy. Our case had a history of Charcot-Marie-Tooth disease. There is a high incidence of arrhythmia and embolic complications. The treatment usually consists of the medical management, defibrillator placement, and lifelong anticoagulation. Heart transplantation will be the last resort.

  11. Rehabilitation of the Mary Kathleen uranium mining and processing site

    Ward, T.A.

    1985-09-01

    A detailed plan for the rehabilitation of the Mary Kathleen mining and processing site was developed prior to the closure of operations in late 1982. The plan was based on three basic principles of: making all areas safe for public access; removing all structures which could deteriorate and become unsightly or unsafe with time; and encouraging natural revegetation on erosion resistant surfaces. The aim was to leave the site in a safe and satisfactory condition, consistent with future land use in the area, requiring no foreseeable ongoing maintenance and a minimum of precautionary monitoring. When the programme has been completed, the only constraint on future land use will be the need to control building construction in the tailings/ evaporation, dumps and mine areas as a precaution against possible exposure to radon daughters. Appropriate radiation and water quality monitoring programmes were incorporated in the plan

    The Mary Kathleen uranium mine and treatment plant ceased operation in late 1982 and a plan for the closure and rehabilitation of the area was developed. The object of the plan is to make all areas safe, remove all non-permanent structures and encourage natural revegetation. The plan has been accepted by the Queensland Mines Department. The mine pit will be left stable, inaccessible to vehicles, and containing about 50 metres of water. Mine waste and borrow areas will be contoured, ripped and seeded to encourage revegetation. The treatment plant area will be cleared of all equipment and light structures, decontaminated and revegetated. The evaporation ponds will be dried out, precipitate and contaminated soil will be removed to the tailings dam, and the area will be contoured and revegetated. The tailings will be covered with one metre of waste rock and boreholes will be used to recover groundwater containing salts for storage in the pit

  15. Therapeutic options in Charcot-Marie-Tooth diseases.

    Science.gov (United States)

    Mathis, Stéphane; Magy, Laurent; Vallat, Jean-Michel

    2015-04-01

    Charcot-Marie-Tooth (CMT) diseases represent a heterogeneous genetic disorder (more than 80 genes are implicated in these inherited neuropathies), but sharing a similar phenotype. In recent years, advances in molecular genetics and molecular biology, and also the development of various animal models of CMT, have led to a better understanding. Taken together, this knowledge represents a prerequisite for the development of future therapies in CMT, and in peripheral nervous system disorders in general. The efficacy of various substances has been shown in vitro and also in vivo (in animal models); but, no significant positive effect has yet been confirmed in humans. However, some of these trials are still in development, and we may expect positive results in the future. Although CMT is still an incurable disease, symptomatic treatments (physiotherapy, surgery, analgesic, etc.) are crucial to improve the quality of life of CMT patients.

  16. Charcot-Marie-Tooth: are you testing for proteinuria?

    Science.gov (United States)

    De Rechter, Stéphanie; De Waele, Liesbeth; Levtchenko, Elena; Mekahli, Djalila

    2015-01-01

    Charcot-Marie-Tooth disease (CMT) is a clinically and genetically heterogeneous group of inherited disorders affecting motor and sensory nerves of the peripheral nervous system. CMT has been reported to be associated with renal diseases, mostly focal segmental glomerulosclerosis (FSGS). However, it was unknown whether these two clinical manifestations represent one common underlying disorder or separate disease entities. Several reports have shown a high prevalence of mutations (75%) in the inverted formin gene (INF2) in patients with CMT-associated glomerulopathy, suggesting that these mutations are a common cause of the dual phenotype. For this reason, we strongly suggest to screen for proteinuria in CMT patients, in order to identify patients with this renal-neurologic phenotype in an early stage, and to perform genetic testing for INF2 mutations.

    Full Text Available Charcot-Marie-Tooth disease (CMT comprises a group of monogenic inherited peripheral neuropathies with highly clinical and genetic heterogeneity, more than 80 causative genes have been cloned at present. Usually starts in childhood or juvinile period, the main clinical manifestations include progressive length.dependent muscle weakness and atrophy, sensory loss, areflexia and pes cavus. Although there is no specific treatment to reverse the natural disease course of CMT, symptomatic treatments such as rehabilitation, orthopedic surgery and medication can improve the overall fitness and life quality of CMT patients. Targeted treatments based on pathogenesis study is expected to provide precise therapy for CMT patients. This paper aims to make a review of the clinical application of symptomatic treatments and progress of target therapy researches in different CMT subtypes. DOI: 10.3969/j.issn.1672-6731.2017.08.003

    2015-03-01

    Full Text Available This paper elaborates a theme at the interface between linguistics and literature on the case example of a novel which belongs to the immigrant literature as part of the contemporary Austrian literature. The Croatian author Ana Bilic describes in her first novel written in German language Das kleine Stück vom großen Himmel (The small part of the big sky published in 2002 the love relationship between a Croatian unnamed female student and the Austrian student Ernst which takes place in Vienna. The unusual thing in this novel is the fact that in numerous sentences and passages the author uses a strange German language which is characterized by interference mistakes, or to be precise a Croatian-German language variation which more or less differs grammatically and lexically from standard German language. In the paper this consciously alienated language is being investigated concerning the influence of the Croatian mother tongue of the author, but also concerning common mistakes while learning German language. The paper also analyses the motivation of Ana Bilic for such in the context of immigrant literature unusual language use, which is also connected with the plot of the novel. Thus qualitative as well as quantitative methods of analysis are being used, whereby the former ones refer to the content and the latter ones to the frequency of interference mistakes in the book. The interference mistakes belong on one side to the fictional (text-internal world and on the other side to the factual (text-external level, because they reflect the plot of the book and establish on the level of content and language a connection between the first-person narrator and the author, who also had to learn German after her arrival to Vienna. As a result of this most interference mistakes appear in the first chapters of the novel, which reflects the first phase in German language learning of the female narrator. Further on in the novel the quantity of the mistakes

    Klein-Nishina scattering cross-sections, Compton scattering, mass attenuation and energy transfer cross-sections, linear attenuation coefficient and buildup factor of paraffin wax are calculated using 0.662 MeV, 0.835 MeV, 1.17 MeV and 1.33 MeV γ-rays. The mentioned γ-rays were obtained from Cs137, Mn54 and Co60 radioisotopes. Gamma rays obtained from these radioisotopes were passed through circular shaped wax slices and allowed to fall on a NaI detector. The thickness of wax slices were 0.33 cm to 2.9 cm with 6 cm diameter. Lead collimator of 1 cm diameter hole in the middle was used to obtain a collimated beam for narrow beam geometry. Broad beam geometry was used by removing collimator, to investigate buildup factor. Results show that Klein-Nishina electronic cross-section, Compton mass attenuation coefficient and Compton energy transfer coefficient all decrease with increasing photon energy. Slope of the thickness vs counts graph for narrow beam geometry gives linear attenuation coefficient μ = 0.0532 cm-1 for 1.17 MeV beam and μ = 0.0419 cm-1 for 1.33 MeV γ-rays. Variations in buildup factors are observed with increasing thickness of wax for 1.17 MeV and 1.33 MeV beams. © 2018 IOP Publishing Ltd.

    Full Text Available The paper reflects on the meanings of the Flores de Mayo ritual as performed in a town on the southeastern coast of Cebu through the examination of Mary as a “semantically open” symbol. The essay illustrates how ideas about Mary are constructed through the discourse of the Church and are in turn, reinforced through a Church-instituted and regulated ritual. An analysis of selected elements of the ritual however, reveals that the symbol of Mary has the potential to hold “other” kinds of meanings that slip in between “official” and “unofficial” discourses, highlighting how Mary continues to be a negotiated field between church authorities and the popular faithful.

    The National Nuclear Security Administration (NNSA) requires the ability to understand and test how material structures, defects, and interfaces determine performance in extreme environments such as in nuclear weapons. To do this, MaRIE will be an x-ray source that is laser-like and brilliant with very fl exible and fast pulses to see at weapons-relevant time scales, and with high enough energy to study critical materials. The Department of Energy (DOE) has determined there is a mission need for MaRIE to deliver this capability. MaRIE can use some of the existing infrastructure of the Los Alamos Neutron Science Center (LANSCE) and its accelerator capability. MaRIE will be built as a strategic partnership of DOE national laboratories and university collaborators.

    We describe a family with Charcot Marie Tooth disease type 4J presenting with features of Charcot Marie Tooth disease plus parkinsonism and aphemia. Genetic testing found two variants in the FIG4 gene: c.122T>C (p.I41T) - the most common Charcot Marie Tooth disease type 4J variant - and c.1949-10T>G (intronic). Proband fibroblasts showed absent FIG4 protein on western blot, and skipping of exon 18 by RT-PCR. As most patients with Charcot Marie Tooth disease type 4J do not have central nervous system deficits, we postulate the intronic variant and I41T mutation together are causing loss of FIG4 protein and subsequently the central nervous system findings in our family.

    We performed whole exome sequencing on a patient with Charcot-Marie-Tooth disease type 1 and identified a de novo mutation in PMP2, the gene that encodes the myelin P2 protein. This mutation (p.Ile52Thr) was passed from the proband to his one affected son, and segregates with clinical and electrophysiological evidence of demyelinating neuropathy. We then screened a cohort of 136 European probands with uncharacterized genetic cause of Charcot-Marie-Tooth disease and identified another family with Charcot-Marie-Tooth disease type 1 that has a mutation affecting an adjacent amino acid (p.Thr51Pro), which segregates with disease. Our genetic and clinical findings in these kindred demonstrate that dominant PMP2 mutations cause Charcot-Marie-Tooth disease type 1. © The Author (2016).

    Data regarding Charcot-Marie-Tooth disease is lacking in Southeast Asian populations. We investigated the frequency of the common genetic mutations in a multiethnic Malaysian cohort. Patients with features of Charcot-Marie-Tooth disease or hereditary liability to pressure palsies were investigated for PMP22 duplication, deletion, and point mutations and GJB1, MPZ, and MFN2 point mutations. Over a period of 3 years, we identified 25 index patients. A genetic diagnosis was reached in 60%. The most common were point mutations in GJB1, accounting for X-linked Charcot-Marie-Tooth disease (24% of the total patient population), followed by PMP22 duplication causing Charcot-Marie-Tooth disease type 1A (20%). We also discovered 2 novel GJB1 mutations, c.521C>T (Proline174Leucine) and c.220G>A (Valine74Methionine). X-linked Charcot-Marie-Tooth disease was found to predominate in our patient cohort. We also found a better phenotype/genotype correlation when applying a more recently recommended genetic approach to Charcot-Marie-Tooth disease. Copyright © 2013 Wiley Periodicals, Inc.

    2012-01-01

    Charcot-Marie-Tooth disease (CMT) is the most common inherited disorder of the peripheral nervous system. The frequency of different CMT genotypes has been estimated in clinic populations, but prevalence data from the general population is lacking. Point mutations in the mitofusin 2 (MFN2) gene has been identified exclusively in Charcot-Marie-Tooth disease type 2 (CMT2), and in a single family with intermediate CMT. MFN2 point mutations are probably the most common cause of CMT2. The CMT phenotype caused by mutation in the myelin protein zero (MPZ) gene varies considerably, from early onset and severe forms to late onset and milder forms. The mechanism is not well understood. The myelin protein zero (P(0) ) mediates adhesion in the spiral wraps of the Schwann cell's myelin sheath. X-linked Charcot-Marie Tooth disease (CMTX) is caused by mutations in the connexin32 (cx32) gene that encodes a polypeptide which is arranged in hexameric array and form gap junctions. Estimate prevalence of CMT. Estimate frequency of Peripheral Myelin Protein 22 (PMP22) duplication and point mutations, insertions and deletions in Cx32, Early growth response 2 (EGR2), MFN2, MPZ, PMP22 and Small integral membrane protein of lysosome/late endosome (SIMPLE) genes. Description of novel mutations in Cx32, MFN2 and MPZ. Description of de novo mutations in MFN2. Our population based genetic epidemiological survey included persons with CMT residing in eastern Akershus County, Norway. The participants were interviewed and examined by one geneticist/neurologist, and classified clinically, neurophysiologically and genetically. Two-hundred and thirty-two consecutive unselected and unrelated CMT families with available DNA from all regions in Norway were included in the MFN2 study. We screened for point mutations in the MFN2 gene. We describe four novel mutations, two in the connexin32 gene and two in the MPZ gene.

    We study the Casimir energy density of the Klein-Gordon-field in the case of two static geometries. We model the effect by coupling the free quantum field to a static classical scalar field. We work out the dependence on the coupling {lambda}, including the limit {lambda}={infinity} (Dirichlet boundary condition). The chosen geometries are described by a {delta}-funktion ({sigma}(x)={delta}(x{sub 3})) and a step function of finite height ({sigma}(x)= (1)/(2{epsilon})1{sub [{epsilon},{epsilon}]}(x{sub 3})), respectively. In the area outside the support of the background the density energy converges; calculations for the distorted area lead to divergent surface terms. (orig.)

    Full Text Available Nel gennaio del 1946 la scrittrice tedesca Marie Luise Kaschnitz pubblica sulla neonata rivista “Die Wandlung” (Il cambiamento il saggio Von der Schuld (Sulla colpa nel quale reagisce, a pochi mesi dalla fine della guerra, alle accuse rivolte da più parti ai Tedeschi di aver consentito al nazismo di trascinare il mondo nella tragedia della Seconda Guerra Mondiale. Le pagine della Kaschnitz sono un documento dimenticato del dibattito, ad oggi inconcluso, sul tema della colpa dei Tedeschi che non opposero resistenza al regime di Adolf Hitler: esse non sono recuperate per decidere sulla condanna o sull’assoluzione della scrittrice e di chi con lei si definì ‘vigliacco’ per aver taciuto, bensì per cercare di comprendere le cause dal punto di vista umano del fenomeno della Innere Emigration, causato dal potere paralizzante esercitato dal regime del terrore, che chiuse ai più ogni via di fuga concreta e, soprattutto, la via della coscienza.

    Princess Marie Bonaparte was a colorful yet mysterious member of Freud's inner circle of psychoanalysis. In analysis with Freud beginning in 1925 (she was then 45 years old), she became a lay analyst and writer of many papers and books. Her most ambitious task was a 700-page psychobiography of Edgar Allan Poe that was first published in French in 1933. She was fascinated by Poe's gothic stories--with the return to life of dead persons and the eerie, unexpected turns of events. Her fascination with Poe can be traced to the similarity of their early traumatic life experiences. Bonaparte had lost her mother a month after her birth. Poe's father deserted the family when Edgar was two years old, and his mother died of tuberculosis when he was three. Poe's stories helped him to accommodate to these early traumatic losses. Bonaparte vicariously shared in Poe's loss and the fantasies of the return of the deceased parent in his stories. She was sensitive and empathetic to Poe's inner world because her inner world was similar. The result of this psychological fit between Poe and Bonaparte was her psychobiography, The Life and Works of Edgar Allan Poe. It was a milestone in psychobiography but limited in its psychological scope by its strong emphasis on early childhood trauma. Nevertheless it proved Bonaparte a bona fide creative psychoanalyst and not a dilettante propped up by her friendship with Freud.

  12. Trading Places: Mary Shelley’s Argument with Domestic Space

    Full Text Available When Mary Shelley began writing The Last Man in 1824 in the wake of her husband Percy Bysshe Shelley’s untimely death, she drew from her close circle of family and friends as models for her main characters. Although it is tempting to view this novel as an autobiographical expiation of the profound sorrow that overwhelmed Shelley at her husband’s death, to do so is to underestimate her prescient political insight and to risk overlooking the complex implications of class and rank that suffuse the position of the narrator, Lionel Verney. While Shelley’s emotions give a passionate appeal to this novel, her intellectual ideas infuse the novel’s powerful critique of British governance. The Last Man is narrated in a political framework in which war and the clash of empires, parliamentary and republican conflict, turbulent revolution, and social and political corruption arrange the fates of the characters. In addition, the plague that silently and invisibly takes over Western Europe and England serves as a spectral process of corrosive malignity from outside, ensnaring all efforts to fix a domestic English system that is collapsing around individuals and the collective.

    Full Text Available Chatcot-Marie-Tooth (CMT is also known as peroneal muscular atrophy and hereditary motor-sensory neuropathy (HMSN. It is the most commonly encountered inherited peripheral neuropathy. Actually, CMT is not a single disease, but is a group of disorders with similar symptoms. CMT type 2 is the second most common form after CMT type1. Symptoms usually begin in childhood or early adulthood. Mostly the peripheral nerves of the lower extremities and occasionaly upper extremities may be affected. Motor nerve involvoment induces distal muscle weakness and atrophy in the lower extremities that may result in foot deformities known as foot drop, pes cavus, pes planus, hammer toe etc. As a result of sensorial nevre degeneration, callus, recurrent foot ulcers, osteonecrosis, osteolysis and spontaneous amputation may accompany the disease. The speed of nerve conduction is not changed in the EMG, but axonal type sensorymotor semptoms that lead to a decrease of amplitude. We report here a 55 year old man with recurrent foot ulcers for 33 years and self amputations, whose EMG findings suggest acsonal neuropathy and who also has a 20 year - old son with similar complaints.

    Obstructive sleep apnoea (OSA) and restless legs syndrome (RLS) have been reported in Charcot-Marie-Tooth disease (CMT) type 1A and axonal subtypes of CMT, respectively. The aim of this case-control study was to investigate both prevalence and severity of OSA, RLS and periodic limb movements in sleep (PLMS) in adult patients with genetically proven CMT1. 61 patients with CMT1 and 61 insomnic control subjects were matched for age, sex, and Body Mass Index. Neurological disability in patients with CMT was assessed using the Functional Disability Scale (FDS). RLS diagnosis was based on a screening questionnaire and structured clinical interviews. All participants underwent overnight polysomnography. OSA was present in 37.7% of patients with CMT1 and 4.9% of controls (psleep quality. In addition to known risk factors, CMT may predispose to OSA. RLS is highly prevalent not only in axonal subtypes of CMT but also in primarily demyelinating subforms of CMT. PLMS are common in CMT1, but do not significantly impair sleep quality.

  15. Restaging Hysteria: Mary Wigman as Writer and Dancer

    Full Text Available Mary Wigman was not only a leading proponent of the early twentieth-century Expressionist dance movement, but also a writer of poetry and short poetic prose. Despite her assertion that dance was beyond language, she wrote often about dance in an attempt to articulate the kinesthetic experience of dance through languages. This interdisciplinary study explores the intersection of dance and writing for Wigman, focusing on gender coding in writing and dance within the context of early twentieth-century dialogues. Despite the pervasive equation of (feminine hysteria with dance and (masculine subjectivity with authorship, Wigman engaged in both activities. I argue that Wigman is able to reclaim and redefine the "hysteria" of the dance experience through writing about dance. In her dance poetry, the act of looking at herself in a mirror as she dances allows Wigman to circumvent the traditional objectification through the male gaze experienced by the female dancer. Through the act of writing, Wigman asserts her subjectivity, taking control of the out-of-body experience of dance creation.

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