  4. Searching for Abraham Flexner.

    PubMed

    Bonner, T N

    1998-02-01

    Although Abraham Flexner (1866-1959) is well known as the author of Medical Education in the United States and Canada: A Report to the Carnegie Foundation for the Advancement of Teaching--so well known that this publication's better-known shorthand title is "the Flexner Report"--for many the "real" Flexner remains something of a mystery. Many today believe that he was overly rigid in his goals for medical education and that he did not adequately champion the rights of women and African Americans, harsh criticisms in late-20th-century America. But who really was Abraham Flexner? The author discusses Flexner the education reformer and the man, highlighting his early years in Louisville and his relationship with his family and his wife, his later graduate work and associations with the Carnegie Foundation for the Advancement of Teaching and the General Education Board, and his then-radical proposals for the reshaping of American medical education. Flexner's attitudes toward women and African Americans are also reviewed, and the author shows that Flexner encouraged both women and blacks to pursue higher education in general and medical careers in particular. Finally, the author discusses Flexner's feelings about his own Jewishness and anti-Semitism, his political beliefs, and his personal attributes as described both by the press and by his friends.

  5. Abraham Lincoln's Gettysburg illness.

    PubMed

    Goldman, Armond S; Schmalstieg, Frank C

    2007-05-01

    When Abraham Lincoln delivered the Gettysburg Address, he was weak and dizzy; his face had a ghastly colour. That evening on the train to Washington, DC, he was febrile and weak, and suffered severe headaches. The symptoms continued; back pains developed. On the fourth day of the illness, a widespread scarlet rash appeared that soon became vesicular. By the tenth day, the lesions itched and peeled. The illness lasted three weeks. The final diagnosis, a touch of varioloid, was an old name for smallpox that was later used in the 20th century to denote mild smallpox in a partially immune individual. It was unclear whether Lincoln had been immunized against smallpox. Indeed, this review suggests that Lincoln had unmodified smallpox and that Lincoln's physicians tried to reassure the public that Lincoln was not seriously ill. Indeed, the successful conclusion of the Civil War and reunification of the country were dependent upon Lincoln's presidency.

  8. Mario Bunge: Physicist and Philosopher

    NASA Astrophysics Data System (ADS)

    Matthews, Michael R.

    Mario Bunge was born in Argentina in the final year of the First World War.He learnt atomic physics and quantum mechanics from an Austrian refugee who had been a student of Heisenberg. Additionally he taught himself modern philosophy in an environment that was a philosophical backwater. He was the first South American philosopher of science to be trained in science. His publications in physics, philosophy, psychology, sociology and the foundations of biology, are staggering in number, and include a massive 8-volume Treatise on Philosophy. The unifying thread of his scholarship is the constant and vigorous advancement of the Enlightenment Project, and criticism of cultural and academic movements that deny or devalue the core planks of the project: namely its naturalism, the search for truth, the universality of science, rationality, and respect for individuals. At a time when specialisation is widely decried, and its deleterious effects on science, philosophy of science, educational research and science teaching are recognised - it is salutary to see the fruits of one person's pursuit of the Big'' scientific and philosophical picture.

  9. Experimental evidence for Abraham pressure of light

    NASA Astrophysics Data System (ADS)

    Zhang, Li; She, Weilong; Peng, Nan; Leonhardt, Ulf

    2015-05-01

    The question of how much momentum light carries in media has been debated for over a century. Two rivalling theories, one from 1908 by Hermann Minkowski and the other from 1909 by Max Abraham, predict the exact opposite when light enters an optical material: a pulling force in Minkowski's case and a pushing force in Abraham's. Most experimental tests have agreed with Minkowski's theory, but here we report the first quantitative experimental evidence for Abraham's pushing pressure of light. Our results matter in optofluidics and optomechanics, and wherever light exerts mechanical pressure.

  10. Abraham-Lorentz versus Landau-Lifshitz

    NASA Astrophysics Data System (ADS)

    Griffiths, David J.; Proctor, Thomas C.; Schroeter, Darrell F.

    2010-04-01

    The classical Abraham-Lorentz formula for the radiation reaction on a point charge suffers from two notorious defects: runaways and preacceleration. Recently, several authors have advocated as an alternative the Landau-Lifshitz formula, which has neither fault. The latter formula is often presented as an approximation to Abraham-Lorentz, raising the delicate question of how an approximation can be considered more accurate than the original. For a spherical shell of finite size, the equation for the radiation reaction is noncontroversial. We begin there, obtain the Abraham-Lorentz and Landau-Lifshitz expressions as limiting cases, and undertake some numerical studies to determine which is superior.

    PubMed

    van Schoonheten, Anna Bentinck

    2010-01-01

    The first psychoanalytic congress in Salzburg has often been described as a great success with one blemish: a conflict between Jung and Abraham, mainly caused by the rivalry in Abraham's behaviour. A new study of the material, and taking Abraham's perspective, provides a different view. Abraham, still a beginner in psychoanalysis, got in the way of Freud and Jung who at that time had a deep theoretical disagreement. In the end they both blamed Abraham.

  12. Abraham Flexner and medical education.

    PubMed

    Ludmerer, Kenneth M

    2011-01-01

    The Flexner Report had its roots in the recognition in the mid-19th century that medical knowledge is not something fixed but something that grows and evolves. This new view of medical knowledge led to a recasting of the goal of medical education as that of instilling the proper techniques of acquiring and evaluating information rather than merely inculcating facts through rote memorization. Abraham Flexner, a brilliant educator, had the background to understand and popularize the meaning of this new view of education, and he took the unprecedented step of relating the developments in medical education to the ideas of John Dewey and the progressive education movement. Although the Flexner Report is typically viewed as a historical document--due to an understandable tendency to refer only to the second half of the report, where Flexner provides his famous critiques of the medical schools that existed at the time--this article argues that the Flexner Report is actually a living educational document of as much significance to medical educators today as in Flexner's time. The article analyzes Flexner's discussion of medical education and shows that his message--the importance of academic excellence, professional leadership, proper financial support, and service and altruism--is timeless, as applicable to the proper education of physicians today and tomorrow as in the past.

  17. Updated Abraham solvation parameters for polychlorinated biphenyls.

    PubMed

    van Noort, Paul C M; Haftka, Joris J H; Parsons, John R

    2010-09-15

    This study shows that the recently published polychlorinated biphenyl (PCB) Abraham solvation parameters predict PCB air-n-hexadecane and n-octanol-water partition coefficients very poorly, especially for highly ortho-chlorinated congeners. Therefore, an updated set of PCB solvation parameters was derived from four PCB properties and associated Abraham solvation equations. Additionally, the influence of ortho-chlorination on PCB solvent accessible volume and surface area was investigated. The updated PCB solvation parameters were tested on partitioning between five other phase combinations. Compared to the original PCB solvation parameter set, the updated PCB solvation parameters resulted in substantially improved estimates from Abraham solvation equations for (subcooled) liquid vapor pressures, aqueous solubilities, HPLC capacity factors, and for coefficients of air-n-hexadecane, air-water, organic carbon-water, and n-octanol-water partitioning. For water to polydimethyl siloxane and sodium dodecylsulphate (SDS) partitioning, the updated PCB solvation parameters yielded no improvement compared to the original data set. The main difference between the updated and the original parameter set is that updated PCB McGowan specific volumes depend on the degree of ortho-chlorination, which is qualitatively confirmed by trends in the PCB solvent accessible volumes and surface areas. The use of the updated PCB solvation parameters instead of the original values is therefore recommended.

  1. Lorentz Abraham Force and Power Equations

    NASA Astrophysics Data System (ADS)

    Yaghjian, Arthur D.

    Toward the end of the nineteenth century Lorentz modeled the electron (“vibrating charged particle,” as he called it) by a spherical shell of uniform surface charge density and set about the difficult task of deriving the equation of motion of this electron model by determining, from Maxwell's equations and the Lorentz force law, the retarded self electromagnetic force that the fields of the accelerating charge distribution exert upon the charge itself [1]. (This initial work of Lorentz in 1892 on a moving charged sphere appeared five years before J.J. Thomson's “discovery” of the electron. It is summarized in English by J.Z. Buchwald [2, app. 7].) With the help of Abraham,1 a highly successful theory of the moving electron model was completed by the early 1900's [3, 4]. Before Einstein's papers [5, 6] on special relativity appeared in 1905, they had derived the following force equation of motion

We thus propose new definitions, which (hopefully) improve the situation. Our definition of system boundary works off the same intuition behind Bunge's.

  4. Abraham Lincoln and the insanity plea.

    PubMed

    Spiegel, A D

    1994-06-01

    A confederate civilian physician shot and killed a white Union officer who was drilling Negro troops in Norfolk, Virginia. With no question as to guilt, President Abraham Lincoln decided to have a medical expert conduct a professional sanity/insanity examination. Documentation indicates that legal and political factors may have influenced Lincoln's decision. As a lawyer, Lincoln prosecuted a case where the insanity plea was used as a defense. Two influential Cabinet members, William H. Seward and Edwin M. Stanton, also had legal experience involving the insanity plea. Politically, Lincoln faced serious issues such as the draft riots, the military necessity to recruit slaves into the army, the impact of Union Negro soldiers upon the border states, the morale and discipline of the army and the upcoming presidential election. Upon Seward's recommendation, Lincoln chose a physician who had a reputation for finding the accused sane and who did so in this case. As the southern physician was hanged, Lincoln's means achieved the desired legal and political ends.

  5. Abraham Lincoln and the global economy.

    Hormats, Robert D

    2003-08-01

    Abraham Lincoln would have well understood the challenges facing many modern emerging nations. In Lincoln's America, as in many developing nations today, sweeping economic change threatened older industries, traditional ways of living, and social and national cohesion by exposing economies and societies to new and powerful competitive forces. Yet even in the midst of the brutal and expensive American Civil war--and in part because of it--Lincoln and the Republican Congress enacted bold legislation that helped create a huge national market, a strong and unified economy governed by national institutions, and a rising middle class of businessmen and property owners. Figuring out how to maximize the benefits of globalization while minimizing its disruptions is a formidable challenge for policy makers. How do you expand opportunities for the talented and the lucky while making sure the rest of society doesn't fall behind? It may be helpful to look at the principles that informed the policies that Lincoln and the Republican Congress instituted after they came to power in 1861: Facilitate the upward mobility of low- and middle-income groups to give them a significant stake in the country. Emphasize the good of the national economy over regional interests. Affirm the need for sound government institutions to temper the dynamics of the free enterprise system. Tailor policies to the national situation. Realize that a period of turmoil may present a unique opportunity for reform. These principles drove the reforms that helped Americans cope with and benefit from rapid technological advances and the fast integration of the American economy in the nineteenth century. They may be instructive to today's policy makers who are struggling to help their own citizens integrate into the fast-changing global economy of the twenty-first century.

  7. Possibility of measuring the Abraham force using whispering gallery modes

    SciTech Connect

    Brevik, I.; Ellingsen, S. A.

    2010-06-15

    Critical experimental tests of the time-dependent Abraham force in phenomenological electrodynamics are scarce. In this paper, we analyze the possibility of making use of intensity-modulated whispering gallery modes in a microresonator for this purpose. Systems of this kind appear attractive, as the strong concentration of electromagnetic fields near the rim of the resonator serves to enhance the Abraham torque exerted by the field. We analyze mainly spherical resonators, although as an introductory step we consider also the cylinder geometry. The orders of magnitude of the Abraham torques are estimated by inserting reasonable and common values for the various input parameters. As expected, the predicted torques turn out to be very small, although probably not beyond reach experimentally. Our main idea is essentially a generalization of the method used by G. B. Walker et al.[Can. J. Phys. 53, 2577 (1975)] for low-frequency fields, to the optical case.

    Mario Bunge was born in Argentina in 1919 and is now in his mid-90s. He studied atomic physics and quantum mechanics with Guido Beck (1903-1988), an Austrian refugee and student of Heisenberg. Additionally he studied modern philosophy in an environment that was a philosophical backwater becoming the first South American philosopher of science to be trained in science. His publications in physics, philosophy, psychology, sociology and the foundations of biology, are staggering in number, and include a massive 8-volume Treatise on Philosophy. The unifying thread of his scholarship is the constant and vigorous advancement of the Enlightenment Project, and criticism of cultural and academic movements that deny or devalue the core planks of the project: namely its naturalism, the search for truth, the universality of science, the value of rationality, and respect for individuals. At a time when specialisation is widely decried, and its deleterious effects on science, philosophy of science, educational research and science teaching are recognised, and at a time when `grand narratives' are thought both undesirable and impossible—it is salutary to appraise the fruits of one person's pursuit of the `Big' scientific and philosophical picture or grand narrative. In doing so this special issue brings together philosophers, physicists, biologists, sociologists, logicians, cognitive scientists, economists and mathematicians to examine facets of Mario Bunge's systematic philosophy and to appraise its contribution to important issues in current philosophy and, by implication, education.

  12. Abraham Lincoln, psychotherapist to the nation: the use of metaphors.

    PubMed

    Leetz, K L

    1997-01-01

    Metaphors are widely utilized in psychotherapy to effect change in patients. Psychotherapeutic metaphors, in their various versions, may offer new choices and ways of viewing oneself to the patient which are more palatable than straight discussions or sterile insights. By addressing resistances indirectly, metaphors can be an effective tool for the therapist to use, regardless of theoretical orientation. Abraham Lincoln, a master of metaphor, utilized this tool effectively in dealing with crises and the ultimate fragmentation, disunion of the national identity. The author argues that Lincoln was able to address complex issues (such as slavery, liberty, nationhood, union, and conduct of the war) with metaphors, much as a skilled psychotherapist addresses complex issues within his or her purview. Abraham Lincoln effectively disarmed his critics, established a means of communication with the people, and sought to make his points in an understandable nonconfrontational fashion. These are skills highly valued by psychotherapists. One might say that Abraham Lincoln conducted psychotherapy on a national scale. Without formal training, he was ultimately able to create a new and more stable sense of national self using a metaphorical approach.

    Traditionally, diabetes education has relied on written materials, with limited resources available for children with diabetes. Mobile games can be effective and motivating tools for the promotion of children's health. In our earlier work, we proposed a novel approach for designing computer games aimed at educating children with diabetes. In this article, we apply our game design to a mobile Android game (Mario Brothers). We also introduce four heuristics that are specifically designed for evaluating the mobile game, by adapting traditional usability heuristics. Results of a pilot study (n = 12) to evaluate gameplay over 1-week showed that the children found the game engaging and improved their knowledge of healthy diet and lifestyle.

    Does the Abraham or the Minkowski momentum describe the momentum transport of light in media? Here we show that this is a question of fluid dynamics. In momentum transport, neither the Abraham nor the Minkowski momentum is fundamental, but they emerge depending on the fluid-mechanical response of the medium on the light. If the fluid is not brought into motion, the Minkowski momentum emerges, if it moves the Abraham momentum appears.

  16. Karl Abraham, Sigmund Freud, and the fate of the seduction theory.

    PubMed

    Good, M I

    1995-01-01

    Even after Freud had turned his attention away from the seduction theory of neurosogenesis, his close pupil and colleague, Karl Abraham, initially sought to investigate child sexual trauma further. In two of the very first articles on child sexual molestation, Abraham proposed that sexual abuse was particularly common among neurotic and psychotic patients as a result of a "traumatophilic diathesis," a trauma-related conceptual precursor of the repetition compulsion. In their correspondence, Freud trenchantly criticized many aspects of Abraham's papers on the subject of sexual trauma, in contrast to his public endorsement of Abraham's work in this area. For largely transferential reasons that this paper attempts to elucidate, Abraham did not encourage dialogue regarding persistent questions on the seduction issue, ceased publishing on that topic, and for some time controlled his apparently deep rankle over Freud's criticisms and failure to acknowledge Abraham's contribution to the concept of the repetition compulsion. Despite their close friendship and shared intellectual enthusiasm, Freud's response to Abraham's 1907 papers, as well as Abraham's almost uniformly positive disposition toward Freud, apparently prevented Abraham from further developing his observations and ideas on seduction and also lent background to their later clash. Subsequently, there was virtually no further psychoanalytic investigation of the subject of child sexual abuse until the issue arose briefly with Ferenczi in the early 1930s, and only occasionally after that for the next fifty years. The death of Abraham, and then Ferenczi, shortly after disputes with Freud may be among the factors that had an inhibiting effect on an earlier reconsideration of the seduction theory by others. Abraham's previously unheralded concept of traumatophilia has relevance to current clinical controversy regarding constitution and sexual trauma.

    Premature closure of one coronal skull suture produces a characteristic arching or relative elevation of the superior orbital rim on the involved side. This sign is associated with facial asymmetry, and both signs are usually the most conspicuous features in patients with mild unilateral coronal craniosynostosis. Photographs suggest that at least 9 individuals over 5 generations of the Abraham Lincoln family had premature closure of 1 coronal suture. In 8 males, there was involvement of the left side; in 1 female, there was involvement of the right side.

    2011-09-01

    High-quality physics instruction is contextualized, motivates students to learn, and represents the discipline as a way of investigating the world rather than as a collection of facts and equations. Inquiry-oriented pedagogy, such as problem-based instruction, holds great promise for both teaching physics content and representing the process of doing real science.2 A challenge for physics teachers is to find instructional contexts that are meaningful, accessible, and motivating for students. Today's students are spending a growing fraction of their lives interacting with virtual environments, and these environments—physically realistic or not—can provide valuable contexts for physics explorations3-5 and lead to thoughtful discussions about decisions that programmers make when designing virtual environments. In this article, I describe a problem-based approach to calculus-based kinematics instruction that contextualizes students' learning within the Super Mario Bros. video game—a game that is more than 20 years old, but still remarkably popular with today's high school and college students.

  1. Abraham Lincoln did not have type 5 spinocerebellar ataxia.

    2009-10-20

    An autosomal dominant genetic disorder, type 5 spinocerebellar ataxia (SCA5), occurs in multiple descendants of one paternal uncle and one paternal aunt of President Abraham Lincoln. It has been suggested that Lincoln himself had the disease and that his DNA should be tested for an SCA5-conferring gene. Herein, I review the pertinent phenotypes of Lincoln, his father, and his paternal grandmother, and conclude that 1) Lincoln's father did not have SCA5, and, therefore, that Lincoln was not at special risk of the disease; 2) Lincoln had neither subclinical nor visible manifestations of SCA5; 3) little evidence suggests SCA5 is a "Lincolnian" disorder; and 4) without additional evidence, Lincoln's DNA should not be tested for SCA5.

  4. Legends about Legends: Abraham Eleazar's Adaptation of Nicolas Flamel.

    PubMed

    Priesner, Claus

    2016-02-01

    This paper explores the relationship between three illustrated alchemical treatises, all of which are associated with Jewish adepts: the famous Le Livre des figures hieroglyphiques attributed to Nicolas Flamel, and two treatises published in 1735 in Erfurt-the Uraltes Chymisches Werckh and the Donum Dei. The Werckh is supposedly written by Rabbi Abraham Eleazar, while the Donum Dei is attributed to an ancient alchemist-cabalist, Rabbi Samuel Baruch. I argue that these authors are fictitious, and that both works were in fact written in the early eighteenth century by their supposed editor, the probably pseudonymous Julius Gervasius. Gervasius connects the Werckh with the legend of Nicolas Flamel by suggesting that it is based on the original, Jewish manuscript which helped Flamel to find the Stone of the Sages. Gervasius used various strategies to confer a sense of Jewish "authenticity" on these works, borrowing from contemporary (non-Jewish) perceptions of Jewish ritual, Hebrew language, and Christian Cabala. The Werckh also borrows and adapts a sequence of allegorical illustrations from those in pseudo-Flamel's Livre, and I compare the two sets of figures and, where possible, interpret them. I conclude that the later works in fact teach us far more about the state of alchemy in the seventeenth and eighteenth centuries than they do about either medieval alchemy or Judaism. PMID:27376176

  5. Ponderomotive forces in electrodynamics of moving media: The Minkowski and Abraham approaches

    In the general setting of the problem, the explicit compact formulae are derived for the ponderomotive forces in the macroscopic electrodynamics of moving media in the Minkowski and Abraham approaches. Taking account of the Minkowski constitutive relations and making use of a special representation for the Abraham energy-momentum tensor enable one to obtain a compact expression for the Abraham force in the case of arbitrary dependence of the medium velocity on spatial coordinates and the time and for nonstationary external electromagnetic field. We term the difference between the ponderomotive forces in the Abraham and Minkowski approaches as the Abraham force not only under consideration of media at rest but also in the case of moving media. The Lorentz force is found which is exerted by external electromagnetic field on the conduction current in a medium, the covariant Ohm law, and the constitutive Minkowski relations being taken into account. The physical argumentation is traced for the definition of the 4-vector of the ponderomotive force as the 4-divergence of the energy-momentum tensor of electromagnetic field in a medium.

  6. Symmetric energy-momentum tensor: The Abraham form and the explicitly covariant formula

    NASA Astrophysics Data System (ADS)

    Nesterenko, V. V.; Nesterenko, A. V.

    2016-03-01

    We compare the known in literature, explicitly covariant 4-dimensional formula for the symmetric energy-momentum tensor of electromagnetic field in a medium and the energy-momentum tensor derived by Abraham in the 3-dimensional vector form. It is shown that these two objects coincide only on the physical configuration space Γ ¯ , formed by the field vectors and the velocity of the medium, which satisfy the Minkowski constitutive relations. It should be emphasized that the 3-dimensional vector formulae for the components of the energy-momentum tensor were obtained by Abraham only on Γ ¯ , and the task of their extension to the whole unconditional configuration space Γ was not posed. In order to accomplish the comparison noted above, we derive the covariant formula a new by another method, namely, by generalizing the Abraham reasoning. The comparison conducted enables one to treat the explicitly covariant formula as a unique consistent extension of the Abraham formulae to the whole configuration space Γ. Thus the question concerning the relativistic covariance of the original 3-dimensional Abraham formulae defined on Γ ¯ is solved positively. We discuss in detail the relativistic covariance of the 3-dimensional vector formulae for individual components of the 4-dimensional tensors in electrodynamics which is manifested in the form-invariance of these formulae under Lorentz transformations.

    Abraham-Moses transformations, besides Darboux transformations, are well-known procedures to generate extensions of solvable potentials in one-dimensional quantum mechanics. Here we present the explicit forms of infinitely many seed solutions for adding eigenstates at arbitrary real energy through the Abraham-Moses transformations for typical solvable potentials, e.g., the radial oscillator, the Darboux-Pöschl-Teller, and some others. These seed solutions are simple generalisations of the virtual state wavefunctions, which are obtained from the eigenfunctions by discrete symmetries of the potentials. The virtual state wavefunctions have been an essential ingredient for constructing multi-indexed Laguerre and Jacobi polynomials through multiple Darboux-Crum transformations. In contrast to the Darboux transformations, the virtual state wavefunctions generate non-polynomial extensions of solvable potentials through the Abraham-Moses transformations.

    2001-04-01

    The author shows how, after Freud struggled in vain from the 1890s to develop a theory of depression, Abraham succeeded for the first time in finding an approach to the understanding of depression a few years before the publication of Freud's 'Mourning and melancholia'. It is contained in his study of the painter Giovanni Segantini (1911), which also includes a description, imbued with a new atmospheric quality, of the mother-son relationship that centres on the concept of the 'bad mother'. The author points out that Abraham's 'good/bad' dimension is effectively absent from Freud's published work up to 1911 and is also at variance with his view of the relationship between son and mother. In later contributions, too, Abraham maintained that unconscious hate directed at the mother, who is experienced as 'bad' but longed for as 'good', was a central factor in the aetiology of depression, a view he had to defend vis-à-vis Freud. The author contends that in the Segantini paper Abraham was describing an inner world similar to that evinced by the work of Melanie Klein and significantly different from Freud's. It is characterised by hate, revenge, death wishes and guilt feelings on the one hand and tranquillity and inner peace on the other.

    The year 2009 witnessed the restoration of the Solar Tower of Astronomical Observatory of Rome, in the INAF main office of Villa Mellini, Monte Mario. This structure underwent a patient restructuring of optics, mechanics and control equipment. Moreover, some areas have been converted into welcome centre for the visitors, so as to transform a scientific instrument - which was active up to a few years ago - into a didactic structure, mainly suitable for school groups. The Solar Tower of Monte Mario, which has been open to the public since January 2010, allows visitors to directly observe the Sun, as well as the spectrum of its light. The Tower therefore becomes an effective didactic instrument in order to teach and talk about a wide range of scientific topics - from Solar Physics to Sun-Earth interactions, to Stellar Evolution. Here we describe the work done by the DivA group of INAF-OAR for putting back into service the Solar Tower, from the technical and didactic viewpoints. We shall also take stock of the activities organized in the first few months of activity.

    The pervasive transcription of our genome presents a possibility of revealing new genomic functions by investigating RNA interactions. Current methods for mapping RNA–RNA interactions have to rely on an ‘anchor' protein or RNA and often require molecular perturbations. Here we present the MARIO (Mapping RNA interactome in vivo) technology to massively reveal RNA–RNA interactions from unperturbed cells. We mapped tens of thousands of endogenous RNA–RNA interactions from mouse embryonic stem cells and brain. We validated seven interactions by RNA antisense purification and one interaction using single-molecule RNA–FISH. The experimentally derived RNA interactome is a scale-free network, which is not expected from currently perceived promiscuity in RNA–RNA interactions. Base pairing is observed at the interacting regions between long RNAs, including transposon transcripts, suggesting a class of regulatory sequences acting in trans. In addition, MARIO data reveal thousands of intra-molecule interactions, providing in vivo data on high-order RNA structures. PMID:27338251

  2. Can the Abraham Light Momentum and Energy in a Medium Constitute a Lorentz Four-Vector?

    NASA Astrophysics Data System (ADS)

    2013-08-01

    By analyzing the Einstein-box thought experiment with the principle of relativity, it is shown that Abraham's light momentum and energy in a medium cannot constitute a Lorentz four-vector, and they consequentially break global momentum and energy conservation laws. In contrast, Minkowski's momentum and energy always constitute a Lorentz four-vector no matter whether in a medium or in vacuum, and the Minkowski's momentum is the unique correct light momentum. A momentum-associated photon mass in a medium is exposed, which explains why only the Abraham's momentum is derived in the traditional "center-of-mass-energy" approach. The EM boundary-condition matching approach, combined with Einstein light-quantum hypothesis, is proposed to analyze this thought experiment, and it is found for the first time that only from Maxwell equations without resort to the relativity, the correctness of light momentum definitions cannot be identified. Optical pulling effect is studied as well.

    2012-06-18

    By restating geometrical optics within the eld-theoretical approach, the classical concept of a photon in arbitrary dispersive medium is introduced, and photon properties are calculated unambiguously. In particular, the canonical and kinetic momenta carried by a photon, as well as the two corresponding energy-momentum tensors of a wave, are derived straightforwardly from rst principles of Lagrangian mechanics. The Abraham-Minkowski controversy pertaining to the de nitions of these quantities is thereby resolved for linear waves of arbitrary nature, and corrections to the traditional formulas for the photon kinetic quantities are found. An application of axiomatic geometrical optics to electromagnetic waves is also presented as an example.

Taking development discourse as a public philosophy of international cooperation, the discussion centers on how Horwitz worked to mediate between health and development. Horwitz endeavored to establish arguments that highlighted the importance of social policy, especially in health; he also strove to reach different audiences and drew connections between elements like health, illness, and labor productivity, without ignoring the humanistic considerations so dear to the public health tradition.

    In 1854, Abraham Lincoln was retained to prepare a state legislative proposal to charter a homeopathic medical college in Chicago. This was a complex task in view of the deep-seated animosity between allopathic or orthodox medical practitioners and irregular healers. Homeopathy was regarded as a cult by the nascent American Medical Association. In addition, the poor reputation of medical education in the United States in general, further complicated the project. Lincoln and influential individuals in Illinois lobbied legislators and succeeded in securing the charter. Subsequently, the Hahnemann Homeopathic Medical College accepted its first class in 1860 and with its successors remained in existence for almost sixty-five years.

  8. Application of axiomatic formal theory to the Abraham-Minkowski controversy

    NASA Astrophysics Data System (ADS)

    Crenshaw, Michael

    Continuum electrodynamics is an axiomatic formal theory whose axioms are the macroscopic Maxwell equations. We demonstrate that valid theorems of the formal theory are inconsistent with conservation laws and with special relativity because continuum electrodynamics allows transformations of the Maxwell equations that constitute an improper tensor transformation that changes the conservation properties, the relativity properties, and the space-time embedding of the coupled equations of motion. The inconsistencies are resolved by a reformulation of physical principles in a flat non-Minkowski material spacetime in which the timelike coordinate corresponds to ct/n. Applying Lagrangian field theory, we derive equations of motion for the macroscopic electric and magnetic fields in a simple dielectric medium. We construct a new formal theory of continuum electrodynamics and we derive a tensor energy-momentum continuity theorem that trivially resolves the century-old Abraham-Minkowski momentum controversy. We derive the theory of special relativity in a dielectric, including the material Lorentz factor and the material Lorentz transformation. We derive the momentum of a polariton in the context of material special relativity to confirm the resolution of the Abraham-Minkowski debate.

    Acredita-se que quando duas estrelas de nêutrons coalescem, elas, eventualmente, formam um buraco negro com massa igual a soma das massas dos objetos originais. Durante a formação do buraco negro, o espaço-tempo em torno do sistema sofre perturbações que se propagam na forma de radiação gravitacional. A forma de onda associada a radiação gravitacional, durante este estágio, aproxima-se a uma senóide exponencialmente amortecida. Este tipo de sinal é conhecido como "ringdown", e seu comportamento e parametrização são muito bem conhecidos. Neste trabalho, simulamos computacionalmente sinais provenientes do "ringdown" de buracos negros, com a finalidade de testar o desempenho do detector de ondas gravitacionais Mario Schenberg em observá-los, quando entrar em funcionamento. Este primeiro teste teórico ajudou-nos a criar estratégias de detecção de sinais imersos no ruído instrumental. Calculamos a relação sinal-ruído como uma função da frequência, bem como sua integral dentro da faixa de sensibilidade do detector. Os resultados obtidos mostraram que o detector Schenberg terá sensibilidade suficiente para detectar este tipo de sinal, proveniente de fontes astrofísicas localizadas dentro de um raio de ~100kpc.

    There is concern about the environmental fate and effects of munition constituents (MCs). Polyparameter linear free energy relationships (pp-LFERs) that employ Abraham solute parameters can aid in evaluating the risk of MCs to the environment. However, poor predictions using pp-LFERs and ABSOLV estimated Abraham solute parameters are found for some key physico-chemical properties. In this work, the Abraham solute parameters are determined using experimental partition coefficients in various solvent-water systems. The compounds investigated include hexahydro-1,3,5-trinitro-1,3,5-triazacyclohexane (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX), hexahydro-1-nitroso-3,5-dinitro-1,3,5-triazine (MNX), hexahydro-1,3,5-trinitroso-1,3,5-triazine (TNX), hexahydro-1,3-dinitroso-5- nitro-1,3,5-triazine (DNX), 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitrobenzene (TNB), and 4-nitroanisole. The solvents in the solvent-water systems are hexane, dichloromethane, trichloromethane, octanol, and toluene. The only available reported solvent-water partition coefficients are for octanol-water for some of the investigated compounds and they are in good agreement with the experimental measurements from this study. Solvent-water partition coefficients fitted using experimentally derived solute parameters from this study have significantly smaller root mean square errors (RMSE = 0.38) than predictions using ABSOLV estimated solute parameters (RMSE = 3.56) for the investigated compounds. Additionally, the predictions for various physico-chemical properties using the experimentally derived solute parameters agree with available literature reported values with prediction errors within 0.79 log units except for water solubility of RDX and HMX with errors of 1.48 and 2.16 log units respectively. However, predictions using ABSOLV estimated solute parameters have larger prediction errors of up to 7.68 log units. This large discrepancy is probably due to the missing R2NNO2

    This research was aimed at investigating how religious beliefs and internalized shame predicted homonegativity. An online survey, which consisted of a self-report questionnaire assessing religious orientation, internalized shame, and internalized homonegativity, was completed by 133 Caucasian and Asian gay men. The respondents also were asked to write a short answer in which they had to explain how they integrated their religion and sexual practices. The quantitative analyses of data demonstrated no significant difference in internalized homonegativity among the two cultural groups. Internalized homonegativity was predicted by the main Abrahamic faiths (i.e. Christianity, Islam, and Judaism) and internalized shame. Qualitative analysis showed that gay men who adhere to a monotheistic religious faith follow a different path to reconciling their religion and homosexuality compared to gay men who adhere to Philosophical/New Age religions or to gay men who have no religious faith. The implications of these findings as well as directions for future research studies were discussed. PMID:25772199

    When Dr. James Simpson began to use anesthesia in child-birth in 1846, a religious furor arose against its use. For many people, including many physicians, Genesis chapter 3, verse 16, implied that childbirth had to be a painful process. In 1849, the editors of one of Canada's medical journals asked Abraham De Sola, Canada's first rabbi, to give his interpretation of Genesis 3:16 for the benefit of their readers, which he did in a three-part article. Using Hebrew biblical scholars as his source, he wrote that the correct interpretation of this passage was that with toil or labor shall women bring forth children, rather than with pain. Therefore, by using anesthesia in childbirth, physicians were not going against the scriptures or the word of God.

Qualitative analysis showed that gay men who adhere to a monotheistic religious faith follow a different path to reconciling their religion and homosexuality compared to gay men who adhere to Philosophical/New Age religions or to gay men who have no religious faith. The implications of these findings as well as directions for future research studies were discussed.

    Abraham Flexner first toured the Yale University School of Medicine in preparation for his report of 1910, but it was just the beginning of his relationship with the school. While his review of Yale in his report was generally favorable, he mentioned several shortfalls that needed to be improved to make the school acceptable. Throughout the next twenty-five years, Flexner worked with Deans George Blumer and Milton C. Winternitz to improve the school’s finances, infrastructure, and quality of education through his work with the Carnegie Foundation and General Education Board. Flexner has been given great accolades for his work on medical education for the country, but little mention is made of him at Yale, even though he was one of the most influential figures in the development of Yale in the last century.

  17. Reduced-order Abraham-Lorentz-Dirac equation and the consistency of classical electromagnetism

    It is widely believed that classical electromagnetism is either unphysical or inconsistent, owing to pathological behavior when self-force and radiation reaction are non-negligible. We argue that there is no inconsistency as long as it is recognized that certain types of charge distribution are simply impossible, such as, for example, a point particle with finite charge and finite inertia. This is owing to the fact that negative inertial mass is an unphysical concept in classical physics. It remains useful to obtain an equation of motion for small charged objects that describes their motion to good approximation without requiring knowledge of the charge distribution within the object. We give a simple method to achieve this, leading to a reduced-order form of the Abraham-Lorentz-Dirac equation, essentially as proposed by Eliezer, Landau, and Lifshitz and derived by Ford and O'Connell.

  18. Abraham Lincoln's blue pills. Did our 16th president suffer from mercury poisoning?

    2001-01-01

    It is well known that Abraham Lincoln took a medicine called "blue mass" or "blue pill," commonly prescribed in the 19th century. What is now hardly known is that the main ingredient of blue mass was finely dispersed elemental mercury. As his friends understood, mercury was often prescribed for melancholy or "hypochondriasis," a condition Lincoln famously endured. Mercury in the form of the blue pill is a potential neurotoxin, which we have demonstrated by recreating and testing the recipe. We present the testimony of many of Lincoln's contemporaries to suggest that Lincoln suffered the neurobehavioural consequences of mercury intoxication but, perhaps crucial to history, before the main years of his presidency; he was astute enough to recognize the effects and stop the medication soon after his inauguration.

  19. Abraham Lincoln's marfanoid mother: the earliest known case of multiple endocrine neoplasia type 2B?

    2012-07-01

    The nature and cause of President Abraham Lincoln's unusual physical features have long been debated, with the greatest attention directed at two monogenic disorders of the transforming growth factor β system: Marfan syndrome and multiple endocrine neoplasia type 2B. The present report examines newly discovered phenotypic information about Lincoln's biological mother, Nancy Hanks Lincoln, and concludes that (a) Lincoln's mother was skeletally marfanoid, (b) the President and his mother were highly concordant for the presence of numerous facial features found in various transforming growth factor β disorders, and (c) Lincoln's mother, like her son, had hypotonic skeletal muscles, resulting in myopathic facies and 'pseudodepression'. These conclusions establish that mother and son had the same monogenic autosomal dominant marfanoid disorder. A description of Nancy Hanks Lincoln as coarse-featured, and a little-known statement that a wasting disease contributed to her death at age 34, lends support to the multiple endocrine neoplasia type 2B hypothesis.

  20. Relativistic Dynamics of a Charged Sphere. Updating the Lorentz-Abraham Model.

    NASA Astrophysics Data System (ADS)

    Yaghjian, Arthur D.

    "This is a remarkable book. […] A fresh and novel approach to old problems and to their solution." Fritz Rohrlich, Emeritus Professor of Physics, Syracuse University This book takes a fresh, systematic approach to determining the equation of motion for the classical model of the electron introduced by Lorentz more than 100 years ago. The original derivations of Lorentz, Abraham, Poincaré and Schott are modified and generalized for the charged insulator model of the electron to obtain an equation of motion consistent with causal solutions to the Maxwell-Lorentz equations and the equations of special relativity. The solutions to the resulting equation of motion are free of pre-acceleration and runaway behavior. Binding forces and a total stress momentum energy tensor are derived for the charged insulator model. General expressions for synchrotron radiation emerge in a form convenient for determining the motion of the electron. Appendices provide simplified derivations of the self-force and power at arbitrary velocity. In this Second Edition, the method used for eliminating the noncausal pre-acceleration from the equation of motion has been generalized to eliminate pre-deceleration as well. The generalized method is applied to obtain the causal solution to the equation of motion of a charge accelerating in a uniform electric field for a finite time interval. Alternative derivations of the Landau-Lifshitz approximation to the Lorentz-Abraham-Dirac equation of motion are also given, along with Spohn’s elegant solution of this approximate equation for a charge moving in a uniform magnetic field. The book is a valuable resource for students and researchers in physics, engineering and the history of science.

    O detector de ondas gravitacionais Mario Schenberg será sensível a sinais que cheguem à Terra com amplitude h~10-21 e dentro da faixa em frequências que varia de 3,0 a 3,4 kHz. As principais fontes astrofísicas em condições de gerar um sinal detectável pela antena Schenberg são: colapsos estelares que produzam eventos do tipo supernova; instabilidades hidrodinâmicas em estrelas de nêutrons; excitação dos modos fluído (modos f) de estrelas de nêutrons; excitação dos primeiros modos quadrupolares de buracos negros com massa ~ 3,8 M¤; coalescências de estrelas de nêutrons e buracos negros em sistemas binários e, ainda, espiralações de mini-buracos negros. Neste trabalho nós determinamos as taxas de eventos para o Schenberg associadas a dois tipos de fontes: através da de-excitação dos modos f de estrelas de nêutrons e através da coalescência de mini-buracos negros de 0,5 M¤ (que atualmente têm sido colocados como possíveis candidatos a objetos massivos do halo Galáctico). Nós mostramos que esses tipos de fontes poderão produzir sinais em ondas gravitacionais com uma taxa em torno de um evento por ano dentro da banda do Schenberg.

    Based on the testimony of others, children learn about a variety of figures that they never meet. We ask when and how they are able to differentiate between the historical figures that they learn about (e.g., Abraham Lincoln) and fantasy characters (e.g., Harry Potter). Experiment 1 showed that both younger (3- and 4-year-olds) and older children (5-, 6-, and 7-year-olds) understand the status of familiar figures, correctly judging historical figures to be real and fictional figures to be pretend. However, when presented with information about novel figures embedded in either a realistic narrative or a narrative with obvious fantasy elements, only older children used the narrative to make an appropriate assessment of the status of the protagonist. In Experiment 2, 3-, and 4-year-olds were prompted to judge whether the story events were really possible or not. Those who did so accurately were able to deploy that judgment to correctly assess the status of the protagonist.

    An improperly healed fracture was the most common reason for the medical malpractice crisis between the 1830s and 1860s in the United States. As a practicing lawyer in Illinois, Abraham Lincoln defended physicians in medical malpractice law suits. One of these was Dr. Powers Ritchey, who was sued for malpractice in 1855. Lincoln agreed to represent Dr. Ritchey in 1858 as the case was appealed to the supreme court of Illinois. In the interim, Lincoln defended two indicted murderers and won acquittals for both. Between the two murder trials, Lincoln debated Stephen A. Douglas while running for U.S. Senator from Illinois. Lincoln believed that Ritchey's case was poorly represented in the lower court. Ritchey's prior attorneys did not file a bill of exceptions to the testimony of the plaintiff's expert medical witnesses. Lincoln attempted to rebut the allegation of a lack of reasonable medical care and diligence by Ritchey, and he sought to secure a new trial for his client. In its decision, the supreme court of Illinois did not find any error and affirmed the lower court's judgment.

    Mario Bunge is one of the most prolific philosophers of our time. Over the past sixty years he has written extensively about semantics, ontology, epistemology, philosophy of science and ethics. Bunge has been interested in the philosophical and methodological implications of modern psychology and more specifically in the philosophies of the relation between the neural and psychological realms. According to Bunge, functionalism, the philosophical stand of current psychology, has limited explanatory power in that neural processes are not explicitly acknowledged as components or factors of psychological phenomena. In Matter and Mind (2010), Bunge has elaborated in great detail the philosophies of the mind-brain dilemma and the basis of the psychoneural identity hypothesis, which suggests that all psychological processes can be analysed in terms of neural and physical phenomena. This article is the result of a long interview with Dr. Bunge on psychoneural identity and brain-behaviour relations.

    2016-07-01

    A characterization of the modelling process in science is proposed for science education, based on Mario Bunge's ideas about the construction of models in science. Galileo's Dialogues are analysed as a potentially fruitful starting point to implement strategies aimed at modelling in the classroom in the light of that proposal. It is argued that a modelling process for science education can be conceived as the evolution from phenomenological approaches towards more representational ones, emphasizing the role of abstraction and idealization in model construction. The shift of reference of theories—from sensible objects to conceptual objects—and the black-box models construction process, which are both explicitly presented features in Galileo's Dialogues, are indicated as highly relevant aspects for modelling in science education.

  7. Reforming medical education in ethics and humanities by finding common ground with Abraham Flexner.

    PubMed

    Doukas, David J; McCullough, Laurence B; Wear, Stephen

    2010-02-01

    Abraham Flexner was commissioned by the Carnegie Foundation for the Advancement of Teaching to conduct the 1910 survey of all U.S. and Canadian medical schools because medical education was perceived to lack rigor and strong learning environments. Existing proprietary schools were shown to have inadequate student scholarship and substandard faculty and teaching venues. Flexner's efforts and those of the American Medical Association resulted in scores of inadequate medical schools being closed and the curricula of the survivors being radically changed. Flexner presumed that medical students would already be schooled in the humanities in college. He viewed the humanities as essential to physician development but did not explicitly incorporate this position into his 1910 report, although he emphasized this point in later writings. Medical ethics and humanities education since 1970 has sought integration with the sciences in medical school. Most programs, however, are not well integrated with the scientific/clinical curriculum, comprehensive across four years of training, or cohesive with nationally formulated goals and objectives. The authors propose a reformation of medical humanities teaching in medical schools inspired by Flexner's writings on premedical education in the context of contemporary educational requirements. College and university education in the humanities is committed to a broad education, consistent with long-standing tenets of liberal arts education. As a consequence, premedical students do not study clinically oriented science or humanities. The medical school curriculum already provides teaching of clinically relevant sciences. The proposed four-year curriculum should likewise provide clinically relevant humanities teaching to train medical students and residents comprehensively in humane, professional patient care.

    The work focuses on the analysis of CO2 and O3 surface variations observed during five summer experimental campaigns carried out at the ‘Icaro Camp’ clean air facility (74.7°S, 164.1°E, 41 m a.s.l.) of the ‘Mario Zucchelli’ Italian coastal research station. This experimental activity allowed the definition of summer average background O3 values that ranged from 18.3 ± 4.7 ppbv (summer 2005-2006) to 21.3 ± 4.0 ppbv (summer 2003-2004). Background CO2 concentrations showed an average growth rate of 2.10 ppmv yr-1, with the highest CO2 increase between the summer campaigns 2002-2003 and 2001-2002 (+2.85 ppmv yr-1), probably reflecting the influence of the 2002/2003 ENSO event. A comparison with other Antarctic coastal sites suggested that the summer background CO2 and O3 at MZS-IC are well representative of the average conditions of the Ross Sea coastal regions. As shown by the analysis of local wind direction and by 3-D back-trajectory calculations, the highest CO2 and O3 values were recorded in correspondence to air masses flowing from the interior of the Antarctic continent. These results suggest that air mass transport from the interior of the continent exerts an important influence on air mass composition in Antarctic coastal areas.

    Environmental protection of Antarctica is a fundamental principle of the Antarctic Treaty. Impact assessment and significance evaluation are due for every human activity on the remote continent. While chemical and biological contaminations are widely studied, very little is known about the electromagnetic pollution levels. In this frame, we have evaluated the significance of the impact of Mario Zucchelli Antarctic Station (Northern Victoria Land) on the local geomagnetic field. We have flown a high resolution aeromagnetic survey in drape mode at 320m over the Station, covering an area of 2km(2). The regional and the local field have been separated by a third order polynomial fitting. After the identification of the anthropic magnetic anomaly due to the Station, we have estimated the magnetic field at the ground level by downward continuation with an original inversion scheme regularized by a minimum gradient support functional to avoid high frequency noise effects. The resulting anthropic static magnetic field at ground extends up to 650m far from the Station and reaches a maximum peak to peak value of about 2800nT. This anthropic magnetic anomaly may interact with biological systems, raising the necessity to evaluate the significance of the static magnetic impact of human installations in order to protect the electromagnetic environment and the biota of Antarctica.

    O detector de ondas gravitacionais MARIO SCHENBERG consistirá de uma massa esférica de cobre-alumínio de 1150kg resfriada a 4K, sobre a qual serão instalados 6 transdutores de nióbio. Com estes trandutores pretende-se converter um possível sinal de onda gravitacional detectado em sinal elétrico, para tanto é necessário que o acoplamento mecânico entre os transdutores e a massa ressonante seja o maior possível. Isto significa que o transdutor deve ser ressonante na mesma freqüência que a antena (aproximadamente 3200Hz). Neste trabalho foi desenvolvida uma geometria para a estrutura mecânica do trandutor. Isto foi feito criando-se modelos em elementos finitos usando-se o "software" MSC/Nastran. Estes modelos criados foram analisados estaticamente (cálculo de tensões) e dinamicamente (cálculo das freqüências de ressonâncias e seus respectivos modos normais) de maneira a se obter o primeiro modo normal do transdutor em 3200Hz. A partir destes cálculos escolheu-se a melhor geometria para o transdutor. Os próximos passos do trabalho serão: usinar este transdutor em uma barra de nióbio e testá-lo à temperatura ambiente e à baixa temperatura. Após isto, pretende-se testá-lo na própria antena resfriada.

    We study the problem of the definition of the energy-momentum tensor of light in general moving non-dispersive media with linear constitutive law. Using the basic principles of classical field theory, we show that for the correct understanding of the problem, one needs to carefully distinguish situations when the material medium is modeled either as a background on which light propagates or as a dynamical part of the total system. In the former case, we prove that the (generalized) Belinfante-Rosenfeld (BR) tensor for the electromagnetic field coincides with the Minkowski tensor. We derive a complete set of balance equations for this open system and show that the symmetries of the background medium are directly related to the conservation of the Minkowski quantities. In particular, for isotropic media, the angular momentum of light is conserved despite of the fact that the Minkowski tensor is non-symmetric. For the closed system of light interacting with matter, we model the material medium as a relativistic non-dissipative fluid and we prove that it is always possible to express the total BR tensor of the closed system either in the Abraham or in the Minkowski separation. However, in the case of dynamical media, the balance equations have a particularly convenient form in terms of the Abraham tensor. Our results generalize previous attempts and provide a first principles basis for a unified understanding of the long-standing Abraham-Minkowski controversy without ad hoc arguments.

    O detector de ondas gravitacionais Mario Schenberg está sendo projetado e construído pelo grupo Gráviton. Sua construção está ocorrendo no Laboratório de Estado Sólido e Baixas Temperaturas (LESBT) da Universidade de São Paulo, na cidade de São Paulo. Esse detector possui uma massa ressonante esférica de cobre-alumínio, com 65 cm de diâmetro, pesando aproximadamente 1150 Kg, suspensa por um sistema de isolamento vibracional, que se encontra em fase de testes preliminares. A real eficácia desse sistema, entretanto, só poderá ser comprovada quando o detector estiver aparelhado com, pelo menos, um transdutor eletromecânico de altíssima sensibilidade acoplado à massa ressonante. Neste momento, não só este sistema de isolamento vibracional será posto em teste, como o do projeto da fiação que transporta os sinais de microondas até os transdutores e destes para a pré-amplificação. Apesar dessa fiação ter sido projetada para não apresentar nenhum contato com a superfície esférica da antena, de maneira a não haver nenhuma transmissão de ruído vibracional do laboratório para esta, deve-se minimizar o ruído microfônico produzido nessa fiação por oscilações mecânicas, uma vez que ela não utiliza nenhum sistema de isolamento vibracional. Com o intuito de resolver este problema, projetamos uma estrutura, formada por pequenos cilindros conectados por barras, a qual não terá nenhuma ressonância mecânica na faixa de freqüências de interesse para detecção (3000 - 3400 Hz). Desta forma, as vibrações nessa faixa não serão amplificadas. O projeto foi feito usando iterativamente, de maneira a otimizar os resultados obtidos, o programa de elementos finitos Msc/Nastran. Através de simulações feitas neste programa, determinamos os parâmetros geométricos ideais a serem utilizados, os quais proporcionam a maior região espectral de interesse livre de ressonâncias.

    Berwick, Donald M; Finkelstein, Jonathan A

    2010-09-01

    In 1910, in his recommendations for reforming medical education, Abraham Flexner responded to what he deemed to be the "public interest." Now, 100 years later, to respond to the current needs of society, the education of physicians must once again change. In addition to understanding the biological basis of health and disease, and mastering technical skills for treating individual patients, physicians will need to learn to navigate in and continually improve complex systems in order to improve the health of the patients and communities they serve. Physicians should not be mere participants in, much less victims of, such systems. Instead, they ought to be prepared to help lead those systems toward ever-higher-quality care for all. A number of innovative programs already exist for students and residents to help integrate improvement skills into professional preparation, and that goal is enjoying increasing support from major professional organizations and accrediting bodies. These experiences have shown that medical schools and residency programs will need to both teach the scientific foundations of system performance and provide opportunities for trainees to participate in team-based improvement of the real-world health systems in which they work. This significant curricular change, to meet the social need of the 21st century, will require educators and learners to embrace new core values, in addition to those held by the profession for generations. These include patient-centeredness, transparency, and stewardship of limited societal resources for health care. PMID:20736631

    Scholars and historians are blind to Lincoln's same-sex inclinations in part because of a personal aversion to male homosexuality, but more importantly because they fail to perceive the vast differences between the sexual culture of antebellum America and that of our own time, especially in regard to male-male physical and emotional intimacy. This article brings those differences to light and sets Lincoln's life in the context of the sexual culture of his own time. This enables one to see that Lincoln's same-sex sexuality was not only unproblematic, but commonplace, if not typical, in his day. Revising the Myth of Lincoln in regard to his same-sex inclinations will have a positive effect on contemporary culture, especially on the education and socialization of young boys.

  1. Super Mario's prison break —A proposal of object-intelligent-feedback-based classical Zeno and anti-Zeno effects

    Super Mario is imprisoned by a demon in a finite potential well on his way to save Princess Peach. He can escape from the well with the help of a flight of magic stairs floating in the space. However, the hateful demon may occasionally check his status. At that time, he has to make a judgement of either jumping to the inside ground immediately in order to avoid the discovery of his escape intention, or speeding up his escape process. Therefore, if the demon checks him too frequently such that there is no probability for him to reach the top of the barrier, he will be always inside the well, then a classical Zeno effect occurs. On the other hand, if the time interval between two subsequent checks is large enough such that he has a higher probability of being beyond the demon's controllable range already, then the demon's check actually speeds up his escape and a classical anti-Zeno effect takes place.

The adequate theoretical description of this regime becomes crucially important with the use of the radiation friction force either in the Lorentz-Abraham-Dirac form, which possesses unphysical runaway solutions, or in the Landau-Lifshitz form, which is a perturbation valid for relatively low electromagnetic wave amplitude. The goal of the present paper is to find the limits of the Landau-Lifshitz radiation force applicability in terms of the electromagnetic wave amplitude and frequency. For this, a class of the exact solutions to the nonlinear problems of charged particle motion in the time-varying electromagnetic field is used.

    Abraham Lincoln was the 16(th) President of the United States of America. On April 14, 1865, shortly after his re-election and the conclusion of the Civil War, Lincoln was shot and killed by John Wilkes Booth. Although numerous physicians tended to the President shortly after his injury, he passed away the next morning. Today, we recognize Lincoln as one of the greatest Presidents in American history. His assassination profoundly influenced the future of the United States, especially as the country was coming back together again following the Civil War. Testaments to his lasting legacy can be seen in many places, from the stone carving of him on Mount Rushmore to his image gracing the $5 bill. What if the President had survived his injury? Would he have had a different outcome utilizing current critical care treatment? Neurotrauma care in 1865 was not yet developed, and head wounds such as the one Lincoln sustained were almost always fatal. The medical attention he received is considered by historians and physicians today to be excellent for that time. We look at the evolution of neurotrauma care during the last 150 years in the US. Particular focus is paid to the advancement of care for penetrating brain injuries in modern trauma centers. PMID:26092530

    Bunge's writings on the mind-body problem provide a rigorous, analytical antidote to the persistent anti-materialist tendency that has characterized the history of philosophy and science. Bunge gives special attention to dualism and its shortcomings, and this attention is welcome in view of the resurgence of the doctrine today. However, I focus my comments selectively on Bunge's more controversial, provocative claims, not to dismiss them, but to engage with them seriously. For example, a difficulty arising from Bunge's rhetorical style and its undoubted virtues is that not all the targets of his selfconfessed "bashings" (2010, xi) are equally deserving. For example, Bunge suggests "most contemporary philosophers of mind are indifferent to psychology, or are remarkably uninformed about it". This charge cannot be sustained today in light of the work of foremost philosophers today.

    Nude psychotherapy is one of the most flamboyant therapeutic techniques ever developed in American psychology. Largely forgotten today, the therapy was an academic and popular sensation upon its introduction in 1967. Developed by psychologist Paul Bindrim, the therapy promised to guide clients to their authentic selves through the systematic removal of clothing. This paper explores the intellectual, cultural and ethical context of nude therapy and its significance as a form of unchurched spirituality. Although nude therapy has an indisputable tabloid character, it is also rooted in a long-standing academic search for authenticity and ultimate meaning through science. Bindrim's career demonstrates the historically long-standing interweaving of spirituality and science within American psychology while simultaneously highlighting the field's extraordinary capacity for adaptive reinvention.

    Continuum electrodynamics is an axiomatic formal theory based on the macroscopic Maxwell equations and the constitutive relations. We apply the formal theory to a thermodynamically closed system consisting of an antireection coated block of dielectric situated in free-space and illuminated by a quasimonochromatic field. We show that valid theorems of the formal theory are proven false by relativity and by conservation laws. Then the axioms of the formal theory are proven false at a fundamental level of mathematical logic. We derive a new formal theory of continuum electrodynamics for macroscopic electric and magnetic fields in a four-dimensional at non-Minkowski material spacetime in which the speed of light is c/n.

    Physicists and historians of physics share a common goal, the quest for understanding, but their objects are different: Physicists attempt to understand Nature, while historians attempt to understand the past, finding both the challenge and joy of history in exploring the contingencies of historical events, their dependence on scientific, biographical, sociopolitical, cultural, and other factors, and shaping them into a coherent narrative. My first example will focus on the history of the photon concept, in particular on the work of Arthur Holly Compton between 1916 and 1922 that led to his discovery of the Compton effect, whose understanding ultimately rested on a close examination of his laboratory notebooks. I will then turn to two episodes in the history of nuclear physics. The first deals with a controversy between 1922 and 1927 between Ernest Rutherford and James Chadwick at the Cavendish Laboratory in Cambridge and Hans Pettersson and Gerhard Kirsch at the Institute for Radium Research in Vienna that involved their fundamentally different experimental observations and theoretical interpretations of the artificial disintegration of nuclei whose resolution could only be understood after uncovering crucial correspondence between the protagonists. The second episode traces George Gamow's creation and development of the liquid-drop model of the nucleus in 1928 and 1929 and its subsequent development in two stages, first by Werner Heisenberg and Carl Friedrich von Weizsäcker from 1933 to 1936, and second by Niels Bohr and Fritz Kalckar in 1936 and 1937, both of which merged in the minds of Lise Meitner and Otto Robert Frisch at the end of 1938 to yield the correct interpretation of nuclear fission, an act of creation whose understanding rested on a detailed analysis of the published literature.

    A computational method was developed which relates the empirical linear solvation energy relationship (LSER) solute polarity parameter, S (formerly denoted ), to two more fundamental quantities: a polarizability term and a computed solvent-accessible-surface electrostatic term. Electrostatics computations were conducted explicitly or with dielectric field polarizable continuum models (PCM, SCIPCM, IPCM), employing a density functional theory (B3LYP/6-311G(2df,2p)) or efficient Hartree-Fock (HF/MIDI!) method for 90 polar and nonpolar organic solutes. Electrostatic parameters calculated at electron isodensity solute surfaces were found to produce significantly better correlations with empirical S values than the same electrostatic parameters deduced from a fixed Bondi atomic radii based surface. The best-fit expression was found employing SCIPCM/IPCM at the 0.0004 e(-)/bohr(3) solvent-accessible-surface: S(fit)() = 0.46E - 0.091SigmaV(s)()(2), with squared correlation coefficient = 0.96 and standard deviation = 0.10, where E is a measured solute excess polarizability scale and SigmaV(s)()(2) is a quantum-calculated solute electrostatic descriptor in kcal A/mol. The resulting model is more accurate than previously developed estimation approaches and relies on only two fitted coefficients; it has the potential advantage of applicability to any solute composed of C, H, N, O, S, F, Cl, and Br. Finally, this investigation offers quantitative insight into the relative contributions of solute polarity and solute polarizability to the empirical LSER polarity parameter, S.

    We see nursing leadership existing at all levels in nursing...all nurses leading. Nurse executives within academic health environments across Canada will be influencing health policy directions and dialogue within the profession nationally. They will be contributing to the development of a national agenda for nursing practice, education, research and leadership. These nurse executives will lead in a way that makes an invigorating impact on human service in health care environments and they will be dedicated to preparing the nursing leaders of tomorrow. The Academy of Canadian Executive Nurses will connect with the Office of Nursing Policy, Canadian Nurses Association, Canadian Association of University Schools of Nursing, Association of Canadian Academic Health Care Organizations and others to develop position papers regarding key issues such as patient safety, health human resource planning and leadership in the Canadian health care system. Our definition of professional nursing practice, fully integrated with education and research, will be advanced through these endeavours. The end result of a strong individual and collective voice will be improved patient outcomes supported by professional nursing practice in positive practice environments. This paper is intended to stimulate dialogue among nursing leaders in Canada, dislodge us from a long and traditional path, and place us firmly in a new millennium of leadership for the profession and practice of nursing, a style of leadership that is needed, wanted and supported by nurses and the clients we serve. It is the responsibility of those of us who lead in academic health science centres to be courageous for the students we support, the puactitioners we lead and the renewal of the profession. We are the testing ground for nursing research, and need to be the source of innovation for nursing practice. It is incumbent on us to leap forward to engage a new vision of the professional practice of nursing with a reconfigured work design and work environment compatible with the new economy, workplace and workforce.

    While the evidence for a clustering of health habits is not particularly strong, there are both pedagogic and economic arguments in favour of a multifaceted approach to health education. The present review thus examines the impact of regular physical exercise upon other forms of health behaviour, testing the extent to which an activity programme can be a catalyst of improved lifestyle in both primary and secondary preventive therapy. The conceptual framework of health promotion is examined with particular reference to the models of Skinner, Becker, Fishbein, Triandis and Rokeach. Certain differences are noted between the decision to exercise and the marketing decisions for which Fishbein's model was originally designed. Nevertheless, in its later modifications, it provides a basic framework for understanding how human lifestyle is shaped. Theoretical mechanisms are suggested whereby exercise could influence such behaviours as cigarette smoking, alcohol consumption and drug usage, seat-belt usage, hypertension, body mass, lipid profile, promiscuous sexual behaviour, the carrying of lethal weapons, and acceptance of regular preventive medical examinations. The empirical evidence from both cross-sectional and longitudinal experiments shows a relatively weak association between exercise habits and other desirable forms of health behaviour. Moreover, it is arguable that other forms of health intervention such as smoking withdrawal or dieting might be equally effective as a primary change agent, and much of the observed association between exercise and other health habits could be attributable to a common dependence on demographic and socio-economic factors. On the other hand, the apparent weakness of associations may arise in part from difficulties in measuring both habitual physical activity and other forms of health behaviour, with a resultant attenuation of correlations. Possibly, a stronger association between exercise participation and other favourable health habits would be uncovered if attention were focused upon those forms of endurance exercise currently thought to enhance cardiac health. Given that moderate endurance exercise is also positive and pleasant advice, further examination of the potential of multifaceted but exercise-centered health promotion programmes appears warranted.

    In view of the critique of the methodology of the dominant interdisciplinary research involving language studies as the main component, in particular clinical linguistics, Cummings (Pragmatic disorders. Perspectives in pragmatics, philosophy and psychology, vol 3. Springer, Dordrecht, 2014) proposes that "It is perhaps appropriate at this point to move the debate onto non-empirical grounds." In Cummings (2014: 113) she starts such a debate on the grounds of the philosophy of language and pragmatics. In this article, I propose to expand that debate by including the input of the philosophy of science. I start the discussion by presenting the way one may carry out language research in the paradigm of empirical sciences from the perspective outlined in Bunge (Scientific research. Strategy and philosophy. Berlin, Springer, 1967; Method, model and matter (synthese library). D. Reidel Publishing Company, Dordrecht, 1973; Emergence and convergence: qualitative novelty and the unity of knowledge.

    Video games can be played in many different contexts. This study examined associations between coplaying video games between siblings and levels of affection and conflict in the relationship. Participants were 508 adolescents (M age = 16.31 years of age, SD = 1.08) who completed questionnaires on video game use and sibling relationships. Participants were recruited from a large Northwestern city and a moderate city in the Mountain West of the United States. Video games played between siblings were coded by an independent sample to assess levels of physical aggression and prosocial behavior in each game. Playing video games with a sibling was associated with higher levels of sibling affection for both boys and girls, but higher levels of conflict for boys only. Playing a violent video game with a brother was associated with lower levels of conflict in the sibling relationship, whereas playing a prosocial video game was not related to any sibling outcome. The value of video games in sibling relationships will be discussed, with a focus on the type of game and the sex of the adolescent. PMID:26748076

    Parametric transducers can work below the quantum limit of sensitivity for resonant mass gravitational wave detectors. This makes them a promising alternative for electromechanical transductance for such detectors. These transducers consist of a reentrant superconducting niobium cavity coupled to a mass-spring system with three mechanical modes. These cavities have a central post responsible for creating a narrow axial gap between its top and the cavity wall, which is a resonant membrane. Their displacement sensitivity (df/dx) increases as the gap spacing decreases. However, this is not a linear relationship and the dimensioning of the cavity becomes critical if the gap is of the order of a few microns. In this paper, we describe how to obtain a gap spacing of ~ 3 μ m and also the development of parametric transducers that will be employed in the coming experimental runs of the Schenberg gravitational wave antenna. Mechanical thinning methods were performed followed by mechanical and electrical frequency measurements to tune the device to operate at the required frequencies. The main results present better frequency stability and an improvement of df/dx by one order of magnitude higher than the preceding models. These results will allow us to reach the quantum limit of detector sensitivity of ~ 10-22 Hz-1/2 in the near future, making it possible to search for gravitational waves around 3.2 kHz.

    The uncontrolled releases of waste effluents to large water bodies have deleterious effects both on water quality and aquatic life. Kano, an industrial city in Nigeria has the largest number of tanneries in the country is facing the problems of impairment of water quality. Levels of heavy metals (Cu, Co, Zn, Mn, Pb, Fe and Cr) were determined using Atomic Absorption spectrophotometric methods. pH, Redox potential (Eh), Temperature, Dissolve Oxygen (DO), Total Dissolve Solid, sulphate, nitrate and phosphate were also determined. Results showed high levels of Cr (2.70±0.57 to 3.12±0.69 mg L-1), Fe (1.21±0.13 to 1.61±0.41 mg L-1) and these values were found to be significantly higher than the maximum permissible limits of FEPA (p<0.05). Levels of Mn, Cu, Zn, Pb and Co were within the minimum permissible limits for effluent discharged into rivers. Increases, in concentrations of heavy metals with distance from point source up to a distance of 400 metres were observed. While anion concentration decreased with distance from point source up to a distance of 400 m. Adherence to pollution control measures and effluent pre-treatment should be enforced in the industries.

  7. Abraham Pais Prize for History of Physics Talk: Henry Cavendish, John Michell, Weighing the Stars

    McCormmach, Russell

    2010-03-01

    This talk is about an interaction between two 18th-century natural philosophers (physical scientists), Henry Cavendish and John Michell, and its most important outcome, the experiment of weighing the world (their name for it) using a torsion balance (our name for it). Michell was the most inventive of the 18th century English natural philosophers, and Cavendish was the first of his countrymen to possess abilities at all comparable with Newton's. By their interests and skills, they were drawn to one another. Both were universal natural philosophers, equally adept at building scientific instruments, performing experiments, constructing theory, and using mathematics; both had a penchant for exacting, quantitative work. Both also had fitful habits of publication, which did not begin to reveal the range of their work, to the mystification of later scientists and historians. Late in life, Cavendish and Michell turned their attention to the force that Newton had examined most completely, a singular triumph of his natural philosophy, the force of universal gravitation. Over the course of the 18th century, abundant evidence of attraction had been gathered from the motions of the earth, moon, planets, and comets, phenomena which span the intermediate range of masses, sizes, and distances. But in three domains of experience, involving the extreme upper and lower limits of masses and dimensions, the universality of gravitation remained an article of faith. These were the gravity of the ``fixed'' stars, the mutual attraction of terrestrial bodies, and the gravitation of light and other special substances. Michell took on himself the task of deducing observable consequences from each of these prospective instances of universal gravitation. Cavendish encouraged Michell, and he followed up the resulting observational and experimental questions. The experiment of weighing the world was the last experiment Mitchell planned and the last experiment Cavendish published. The capstone of two distinguished careers, the experiment outlived the world in which it was conceived and carried out. Today gravitation is at the center of the physics of the very small and the very large, and experiments that followed in Michell and Cavendish's footsteps find a place in it. The ``most important advance in experiments on gravitation,'' to quote an authority, ``was the introduction of the torsion balance'' by Michell and Cavendish and independently by Coulomb; ``it has been the basis of all the most significant experiments on gravitation ever since.'' Another authority traces the ``noble tradition of precision measurement to which we are heirs'' to Cavendish's experiment, which he calls the ``first modern physics experiment.''

  8. The Abraham Pais Prize Lecture: The historical Development of the Physical Concept of Time

    NASA Astrophysics Data System (ADS)

    Jammer, Max

    2007-04-01

    The Irish physicist and mathematician John Lighton Synge once (1959) proclaimed that of all physical measurements that of time is the most fundamental and its theory ``the most basic theory of all.'' Twenty years later the Belgian physicist and chemist Ilya Prigogine declared that ``the concept of time is much more complex than we thought.'' Indeed, having studied the basic notions in physics like space, mass, force, simultaneity and written on each of them a detailed monograph, I always postponed a similar treatment of the concept of time because I realized that just by being the ``most basic'' it is also the most ``complex'' of all notions in physics and therefore a rather complicated subject of research. In fact, time, as perceived by us, is both ``flowing'' and ``enduring'' and its ``passing'' always ``lasts.'' If I venture nevertheless to offer herewith a survey of the conceptual development of the notion of time, I do so because I delimit myself to the role of time only in physics and ignore as far as possible general metaphysical, psychological or biological issues. The presentation thus ignores the history of the notion of time as conceived in the myths and religions of ancient civilizations and begins, after some brief remarks about the Pythagoreans, with the theories of time as proposed by the Pre-Socratics, Plato and Aristotle. After a critical discourse on the early proponents of an idealistic interpretation of the notion of time, like that of St. Augustine, medieval theories of time, like those which proposed the atomicity of time, are discussed. After a presentation of sixteenth century discussions of time, like that by Bruno or Gassendi, Isaac Barrow's and Isaac Newton's theories of physical time are critically analyzed. This is followed by a brief study of the conceptions of time by Locke and Berkeley and subsequently by Leibniz, who is often regarded as the first proponent of a relational or causal theory of time. Following some brief remarks about Hume's conception of time Kant's critical investigation of the notion of time is analyzed and followed by the theories of an ``arrow if time'' as a result of the existence of irreversible thermodynamic processes. After a brief discussion of Poincar'e's thesis of the conventional status of temporal metric, Einstein's interpretation of distant simultaneity and consequently his definition of time via simultaneity, as presented in his famous 1905 paper on relativity, are discussed. This is followed by some remarks on the concept of time in the general theory of relativity. A brief outline of the role of the concept of time in modern cosmology and, in particular, Hawking's notion of ``imaginary time'' conclude this essay.

In an era of technological breakthroughs in the field of forensic DNA analysis, the importance of the scientist's attention to the evidence presented in each case is stressed.

  11. Abraham Pais Prize for History of Physics: Physics Textbooks Don't Always Tell the Truth

    Anyone who studies the history of physics quickly realizes that the history of physics presented in physics textbooks is often inaccurate. This is not necessarily a bad thing. The purpose of textbooks is to help students learn physics. An inaccurate history may serve a pedagogical purpose. It may help to explain concepts more clearly than the actual history. I believe, however, that it is important for those of us who teach physics to know the accurate history. In this talk I will discuss two episodes from the history of modern physics, Millikan's experiments on the photoelectric effect and the Ellis-Wooster experiment on the energy spectrum in β decay. Everyone knows that Millikan's work established the photon theory of light. The problem is that what everyone knows is wrong. The Ellis-Wooster experiment, on the other hand, is rarely discussed in physics texts, but it should be. In this talk I will present a more accurate history of these experiments.

  13. Abraham Lincoln's suit against a medical imposter who assaulted his client.

    Spiegel, A D; Kavaler, F

    2001-10-01

    In 1851, A. Lincoln, Esquire represented Edward Jones who charged in a law suit that his attending physician had assaulted him. Jones, also a lawyer, had sharply questioned Dr. Joseph S. Maus about his claims of attendance and graduation from Philadelphia's Jefferson Medical College, an allopathic medical school. Jones claimed that Maus became enraged at his persistent questioning and attacked him. In turn, Maus denied the allegation. He said that he was merely defending himself from Jones' blows with a large cane. Lincoln's legal approach was to argue about the state of medical education and whether Maus had really graduated from Jefferson Medical College. Acting as a peacemaker, he finally arranged to settle the dispute between Jones and Maus out of court.

  14. Measuring the Immeasurable: Or "Could Abraham Lincoln Take the Implicit Association Test?".

    2007-12-01

    With the Association for Psychological Science's new ethical standards requiring that all research studies include an Implicit Association Test (IAT), forecasters predict that the population of new participants available to take IATs will expire by the year 2023. Shrill, doomsday proposals from IAT experts involve rationing the precious pool of remaining IAT novices or other naive strategies. These solutions demonstrate rigid, scientific thinking, with a distinct lack of the creative flair that makes psychology stand apart from the real sciences. Building on our prior experience of adapting the IAT for measuring infant cognition and rooting out aliens among us, we demonstrate that new pools of participant resourcesmdash;the unborn and passed on-are available, if we take the time to develop the methods to exploit them. Two studies illustrate some of the methodological challenges and opportunities that must be met in order to make better use of the new populations to keep the IAT juggernaut on its path of global (and interstellar) domination.

    Video gaming is a highly pervasive activity, providing a multitude of complex cognitive and motor demands. Gaming can be seen as an intense training of several skills. Associated cerebral structural plasticity induced has not been investigated so far. Comparing a control with a video gaming training group that was trained for 2 months for at least 30 min per day with a platformer game, we found significant gray matter (GM) increase in right hippocampal formation (HC), right dorsolateral prefrontal cortex (DLPFC) and bilateral cerebellum in the training group. The HC increase correlated with changes from egocentric to allocentric navigation strategy. GM increases in HC and DLPFC correlated with participants' desire for video gaming, evidence suggesting a predictive role of desire in volume change. Video game training augments GM in brain areas crucial for spatial navigation, strategic planning, working memory and motor performance going along with evidence for behavioral changes of navigation strategy. The presented video game training could therefore be used to counteract known risk factors for mental disease such as smaller hippocampus and prefrontal cortex volume in, for example, post-traumatic stress disorder, schizophrenia and neurodegenerative disease.

  1. Eponymous doctors associated with Edinburgh, part 3--Abraham Colles, Sir William Ferguson, John S Haldane, Argyll Robertson, Thomas Young.

    PubMed

    Doyle, D

    2007-03-01

    In the first papers in this series, it was shown that eponyms were often bestowed on physicians and surgeons who were already famous, had made many discoveries never honoured with eponyms, and were often the leading doctors of their day. Only occasionally was the eponym suggested by a friend or colleague; more usually it was a doctor abroad who wanted to show respect to a great man but the choice of the particular syndrome or discovery was a random one. Eponyms may have had their uses. They were usually much shorter than a detailed description of a medical syndrome or anatomical feature and may sometimes have been used as euphemisms in much the same way as, until recently, bedside teachers protected the patients by speaking of 'mitotic lesions' or 'neoplasms', 'Hansen's Disease' or 'acid-fast bacilli'. The conferring and use of eponyms appears to be lessening but, as shown in this final paper, they are still used and possibly useful, and can tell us things of interest about the recipient and the proposer.

    An unstable hemoglobin variant was identified in a Negro woman with hemolytic anemia since infancy. A splenectomy had been performed when the patient was a child. The anemia was accompanied by erythrocyte inclusion bodies and excretion of darkly pigmented urine. Neither parent of the proposita demonstrated any hematologic abnormality, and it appeared that this hemoglobin variant arose as a new mutation. Erythrocyte survival in the patient was greatly reduced: the erythrocyte t½ using radiochromium as a tag was 2.4 days, and a reticulocyte survival study performed after labeling the cells with L-[14C]leucine indicated a t½ of 7.2 days. When stroma-free hemolysates were heated at 50°C, 16-20% of the hemoglobin precipitated. The thermolability was prevented by the addition of hemin, carbon monoxide, or dithionite, suggesting an abnormality of heme binding. An increased rate of methemoglobin formation was also observed after incubation of erythrocytes at 37°C. The abnormal hemoglobin could not be separated from hemoglobin A by electrophoresis or chromatography, but it was possible to isolate the variant β-chain by precipitation with p-hydroxymercuribenzoate. Purification of the β-chain by column chromatography followed by peptide mapping and amino acid analysis demonstrated a substitution of proline for β32 leucine. It appears likely that a major effect of this substitution is a disruption of the normal orientation of the adjacent leucine residue at β31 to impair heme stabilization. Images PMID:4352462

  4. Abraham Pais Prize for History of Physics Lecture: Big, Bigger, Too Big? From Los Alamos to Fermilab and the SSC

    NASA Astrophysics Data System (ADS)

    Hoddeson, Lillian

    2012-03-01

    The modern era of big science emerged during World War II. Oppenheimer's Los Alamos laboratory offered the quintessential model of a government-funded, mission-oriented facility directed by a strong charismatic leader. The postwar beneficiaries of this model included the increasingly ambitious large laboratories that participated in particle physics--in particular, Brookhaven, SLAC, and Fermilab. They carried the big science they practiced into a new realm where experiments eventually became as large and costly as entire laboratories had been. Meanwhile the available funding grew more limited causing the physics research to be concentrated into fewer and bigger experiments that appeared never to end. The next phase in American high-energy physics was the Superconducting Super Collider, the most costly pure physics project ever attempted. The SSC's termination was a tragedy for American science, but for historians it offers an opportunity to understand what made the success of earlier large high-energy physics laboratories possible, and what made the continuation of the SSC impossible. The most obvious reason for the SSC's failure was its enormous and escalating budget, which Congress would no longer support. Other factors need to be recognized however: no leader could be found with directing skills as strong as those of Wilson, Panofsky, Lederman, or Richter; the scale of the project subjected it to uncomfortable public and Congressional scrutiny; and the DOE's enforcement of management procedures of the military-industrial complex that clashed with those typical of the scientific community led to the alienation and withdrawal of many of the most creative scientists, and to the perception and the reality of poor management. These factors, exacerbated by negative pressure from scientists in other fields and a post-Cold War climate in which physicists had little of their earlier cultural prestige, discouraged efforts to gain international support. They made the SSC crucially different from its predecessors and sealed its doom.

    The initiation of combat in Iraq and Afghanistan has resulted in a new cohort of active-duty service members and veterans seeking rehabilitation care through the U.S. Department of Veterans Affairs (VA). Service members injured in combat most often sustain multiple injuries (polytrauma) and require a unique service delivery model to meet their needs. The VA recognized this need and responded with the development of the Polytrauma System of Care (PSC). This national system of care balances access and expertise to provide specialized life-long care to the combat injured. The PSC is comprised of: 4 specialized regional rehabilitation centers that are accredited in brain injury by the Commission on Accreditation of Rehabilitation Facilities; 21 specialized outpatient and subacute rehabilitation programs; designated polytrauma teams at smaller, more remote VA facilities; and a point of contact at all other VA facilities. In addition, the PSC has developed a proactive case-management model, a specialized telehealth network, guidelines for long-term follow-up, and services for those individuals who are unable to return home. The following commentary and articles provide additional detail on this new and unique system of care.

    2008-11-01

    On the night of August 19, 2000, at the foot of Castel del Monte, an 8-year-old girl was brutally murdered. The perpetrators were identified as five young men who captured their victim and sexually abused her. The policemen found the cadaver by following "Mario," one of the five, who had been discovered lying on the ground, near the castle. Investigation led to demonstrate that the murder was not premeditated. The only desire of the group was to sexually molest the little girl. Mario showed signs of psychiatric pathology and for that he underwent psychiatric evaluation by judicial authorities. Analysis of this case, combined with a criminological and medical-legal perspective led to conclusions very much different from the expectations of Mario's defense attorneys. Mario, a marginal figure and seemingly the least intelligent, played the role of group instigator, both in the initiation of sexually abusing the child, as well as in the elimination of an inconvenient witness. However, the group was able to activate Mario's sadistic fantasies and his sexual perversions, and he ended up in a catalyzing role influencing the behavior of others and realizing what would otherwise remain only fantasies. The circularity of the group allows people like Mario, who are apparently subordinate, to influence the behavior of others. Mario was found to have a mental disorder but it was not sufficient to diminish his personal responsibility related to the crime. In fact, according to Italian judicial code, it is necessary that the motivation for the crime was psychopathological. It was for this reason that, according to Italian law, all of the members of the group were considered to be responsible for the crimes committed and were condemned.

  14. The momentum of an electromagnetic wave inside a dielectric

    NASA Astrophysics Data System (ADS)

    Testa, Massimo

    2013-09-01

    The problem of assigning a momentum to an electromagnetic wave packet propagating inside an insulator has become known under the name of the Abraham-Minkowski controversy. In the present paper we re-examine this issue making the hypothesis that the forces exerted on an insulator by an electromagnetic field do not distinguish between polarization and free charges. Under this assumption we show that the Abraham expression for the radiation mechanical momentum is highly favored.

  16. The momentum of an electromagnetic wave inside a dielectric

    SciTech Connect

    Testa, Massimo

    2013-09-15

    The problem of assigning a momentum to an electromagnetic wave packet propagating inside an insulator has become known under the name of the Abraham–Minkowski controversy. In the present paper we re-examine this issue making the hypothesis that the forces exerted on an insulator by an electromagnetic field do not distinguish between polarization and free charges. Under this assumption we show that the Abraham expression for the radiation mechanical momentum is highly favored. -- Highlights: •We discuss an approximation to treat electrodynamics of a dielectric material. •We support the Abraham form for the electromagnetic momentum. •We deduce Snell’s law from the conservation of the Abraham momentum. •We show how to deal with the electric field discontinuity at the dielectric boundary.

  17. Detection of eccentricity in silver nanotubes by means of induced optical forces and torques

    NASA Astrophysics Data System (ADS)

    Ekeroth, R. M. Abraham; Lester, M. F.

    2015-10-01

    In previous works (Abraham et al 2011 Plasmonics 6 435; Abraham Ekeroth and Lester 2012 Plasmonics 7 579; Abraham Ekeroth and Lester 2013 Plasmonics 8 1417; Abraham Ekeroth R M and Lester M 2015 Plasmonics 10 989-98), we have conducted an exhaustive study about optical properties of metallic realistic two-dimensional (2D) nanotubes, using an experimental-interpolated dielectric function (Palik 1985 Handbook of Optical Constants of Solids (Toronto: Academic Press)). In the case of non-homogeneous metallic shells, we suggested (in a theoretical form) a procedure to detect the non-uniformity of shells in parallel, disperse and randomly oriented long nanotubes (2D system). This detection is based exclusively on the plasmonic properties of the response (Abraham Ekeroth and Lester 2012 Plasmonics 7 579). Here we consider exact calculations of forces and torques, exerted by light on these kinds of nanostructures, illustrating the mechanical effects of plasmonic excitations with one example of silver shell under p-polarized incidence. This study continues with the methodology implemented in the previous paper (Abraham Ekeroth R M and Lester M 2015 Plasmonics 10 989-98), for homogeneous nanotubes. The features of the electromagnetic interaction in these structures, from the point of view of mechanical magnitudes, make it possible to conceive new possible interesting applications. Particularly, we point out some results regarding detection of eccentricity in nanotubes in vacuum (when Brownian movement is not taken into account). We interpret the optical response of the realistic shells in the framework of plasmon hybridization model (PHM), which is deduced from a quasi-static approximation. Our integral formalism provides for retardation effects and possible errors is only due to its numerical implementation.

  18. Surface deformation effects induced by radiation pressure and electrostriction forces in dielectric solids

    NASA Astrophysics Data System (ADS)

    Astrath, N. G. C.; Lukasievicz, G. V. B.; Malacarne, L. C.; Bialkowski, S. E.

    2013-06-01

    The surface displacement produced by radiation pressure and electrostriction forces is investigated considering the commonly accepted theories proposed by Minkowski and Abraham for the energy-momentum tensor. The contributions are modeled considering each effect separately assuming non-absorbing and absorbing solids and the thermoelastic deformation equations are solved numerically. We show that the surface deformation profiles as calculated by the Minkowski or Abraham momenta give different surface curvature, which could in principle be detected by measuring the surface displacement. Finally, an all-optical pump-probe photothermal method to detect the radiation pressure and electrostriction forces in transparent dielectric solids is proposed.

    NASA Astrophysics Data System (ADS)

    Partanen, Mikko; Häyrynen, Teppo; Oksanen, Jani; Tulkki, Jukka

    2016-03-01

    During the past century the electromagnetic field momentum in material media has been under debate in the Abraham-Minkowski controversy as convincing arguments have been advanced in favor of both the Abraham and Minkowski forms of photon momentum. Here we study the photon momentum and optical forces in cavity structures in the cases of dynamical and steady state fields. In the description of the single-photon transmission process we use a field-kinetic one-photon theory. Our model suggests that in the medium photons couple with the induced atomic dipoles forming polariton quasiparticles with the Minkowski form momentum. The Abraham momentum can be associated to the electromagnetic field part of the coupled polariton state. The polariton with the Minkowski momentum is shown to obey the uniform center of mass of energy motion that has previously been interpreted to support only the Abraham momentum. When describing the steady state non-equilibrium field distributions we use the recently developed quantized fluctuational electrodynamics (QFED) formalism. While allowing detailed studies of light propagation and quantum field fluctuations in interfering structures, our methods also provide practical tools for modeling optical energy transfer and the formation of thermal balance in nanodevices as well as studying electromagnetic forces in optomechanical devices.

  14. Total longitudinal momentum in a dispersive optical waveguide.

    PubMed

    Yu, Jianhui; Chen, Chunyan; Zhai, Yanfang; Chen, Zhe; Zhang, Jun; Wu, Lijun; Huang, Furong; Xiao, Yi

    2011-12-01

    Using the Lorentz force law, we derived simpler expressions for the total longitudinal (conserved) momentum and the mechanical momentums associated with an optical pulse propagating along a dispersive optical waveguide. These expressions can be applied to an arbitrary non-absorptive optical waveguide having continuous translational symmetry. Our simulation using finite difference time domain (FDTD) method verified that the total momentum formula is valid in a two-dimensional infinite waveguide. We studied the conservation of the total momentum and the transfer of the momentum to the waveguide for the case when an optical pulse travels from a finite waveguide to vacuum. We found that neither the Abraham nor the Minkowski momentum expression for an electromagnetic wave in a waveguide represents the complete total (conserved) momentum. Only the total momentum as we derived for a mode propagating in a dispersive optical waveguides is the 'true' conserved momentum. This total momentum can be expressed as PTot = -U Die/(vg) + neff (U/c). It has three contributions: (1) the Abraham momentum; (2) the momentum from the Abraham force, which equals to the difference between the Abraham momentum and the Minkowski momentum; and (3) the momentum from the dipole force which can be expressed as -UDie/vg. The last two contributions constitute the mechanical momentum. Compared with FDTD-Lorentz-force method, the presently derived total momentum formula provides a better method in terms of analyzing the permanent transfer of optical momentum to a waveguide.

    Two separate-effect experiments in the HFR and OSIRIS Material Test Reactors (MTRs) are currently under Post- Irradiation Examinations (MARIOS) and under preparation (DIAMINO) respectively. The main goal of these experiments is to investigate gaseous release and swelling of Am-bearing UO2-x fuels as a function of temperature, fuel microstructure and gas production rate. First, a brief description of the MARIOS and DIAMINO irradiations is provided. Then, the innovative experimental in-pile device specifically developed for the DIAMINO experiment is described. Eventually, the thermo-mechanical computations performed using the LICOS code are presented. These simulations support the DIAMINO experimental design and highlight some of the capabilities of the code. (authors)

    2016-01-22

    The determination of Abraham descriptors for single ions is reviewed, and equations are given for the partition of single ions from water to a number of solvents. These ions include permanent anions and cations and ionic species such as carboxylic acid anions, phenoxide anions and protonated base cations. Descriptors for a large number of ions and ionic species are listed, and equations for the prediction of Abraham descriptors for ionic species are given. The application of descriptors for ions and ionic species to physicochemical processes is given; these are to water-solvent partitions, HPLC retention data, immobilised artificial membranes, the Finkelstein reaction and diffusion in water. Applications to biological processes include brain permeation, microsomal degradation of drugs, skin permeation and human intestinal absorption. The review concludes with a section on the determination of descriptors for ion-pairs.

  13. Higher order terms of radiative damping in extreme intense laser-matter interaction

    SciTech Connect

    Pandit, Rishi R.; Sentoku, Yasuhiko

    2012-07-15

    The higher order terms of the Lorentz-Abraham-Dirac equation have been derived, and their effects are studied via a relativistic collisional particle-in-cell simulation. The dominant group of terms up to the fourth order of the Lorentz-Abraham-Dirac equation is identified for ultra-intense laser-matter interactions. The second order terms are found to be the damping terms of the Lorentz force while the first order terms represent friction in the equation of motion. Because the second order terms restrict electron acceleration during the laser interaction, electrons/ions are prevented from over-accelerating. Radiative damping becomes highly significant when I{>=} 10{sup 22} W/cm{sup 2} while Bremsstrahlung will be saturated, thus radiative damping will be a dominant source of hard x-rays in regimes at extreme intensities.

  14. Optical pressure deduced from energy relations within relativistic formulations of electrodynamics

    NASA Astrophysics Data System (ADS)

    Sheppard, Cheyenne J.; Kemp, Brandon A.

    2014-01-01

    The analysis of plane waves normally incident upon moving media yields a velocity-dependent net flow of electromagnetic energy within the system such that optical pressures are deduced. Two common formulations (Chu and Minkowski) are employed to model the phenomena with respect to the Abraham-Minkowski debate. Within the framework of relativistic electrodynamics, two perfect reflectors submerged in a dielectric are used to compare the calculated optical work and pressure exerted to the system for both formulations via momentum and energy conservation. The perfect reflectors are represented by having zero electric field and zero magnetic field at the surface of the perfect electrical conductor and the perfect magnetic conductor, respectively. Comparison of these results gives valuable insight into the differences between Abraham and Minkowski momenta and provides theoretical evidence as to observable effects in actual optical moment transfer to media.

  15. Dependence of the Radiation Pressure on the Background Refractive Index

    NASA Astrophysics Data System (ADS)

    Webb, Kevin J.

    2013-07-01

    The 1978 experiments by Jones and Leslie showing that the radiation pressure on a mirror depends on the background medium refractive index have yet to be adequately explained using a force model and have provided a leading challenge to the Abraham form of the electromagnetic momentum. Those experimental results are predicted for the first time using a force representation that incorporates the Abraham momentum by utilizing the power calibration method employed in the Jones and Leslie experiments. With an extension of the same procedure, the polarization and angle independence of the experimental data are also explained by this model. Prospects are good for this general form of the electromagnetic force density to be effective in predicting other experiments with macroscopic materials. Furthermore, the rigorous representation of material dispersion makes the representation important for metamaterials that operate in the vicinity of homogenized material resonances.

  17. An anatomical commentary on the concept of infantile oral sadism.

    PubMed

    Freeman, R; Freeman, T

    1992-01-01

    Although this paper is entitled 'An anatomical commentary on the concept of infantile oral sadism' it is also an attempt to examine hypotheses regarding the sources of oral sadism. Freud did not explicitly refer to an oral sadistic phase of development in early infancy, believing as he did that sadism was a component instinct. Abraham postulated that oral sadism arises when the teeth erupt and the jaw muscles function. Melanie Klein, however, came to claim that oral sadistic impulses operate from birth and arise from the infant's innate potential for fantasy. This hypothesis is akin to Freud's theory of primal fantasies. The anatomical record supports Abraham's theory of the source of oral sadism. PMID:1512124

    Circumcision is the oldest documented surgical procedure. Practiced for ritual religious and likely medical purposes, it seems to have emerged in Egypt and was adopted by the western Semitic tribes. In biblical times, circumcision became a religious doctrine described in the Covenant between God and Abraham in the book of Genesis. Although some claim that there are medical advantages to being circumcised, available data do not support a medical benefit for circumcision.

    We are interested in the motion of a classical charge acted upon an external constant electromagnetic field where the back reaction of the particle's own field is taken into account. The Landau-Lifshitz approximation to the Lorentz-Abraham-Dirac equation is solved exactly and in closed form. It is shown that the ultrarelativistic limit of the Landau-Lifshitz equation for a radiating charge is the equation for eigenvalues and eigenvectors of the external electromagnetic field tensor.

    A thin layer of decane liquid floating above the surface of water is compressed in thickness when exposed to a radiation by an infrared laser in normal incidence. This is believed to result from an inward radiation pressure received by the decane film as light crosses successively the air-decane interface and the decane-water interface. The experimental results support Abraham's formulation for the momentum of light. Thermo-effects may also contribute.

    Radiation losses of charged particles can become important in ultra high intensity laser plasma interaction. This process is described by the radiation back reaction term in the electron equation of motion. This term is implemented in the relativistic particle-in-cell code by using a renormalized Lorentz-Abraham-Dirac model. In the hole boring regime case of laser ion acceleration it is shown that radiation losses results in a decrease of the piston velocity.

    Abraham Maslow's hierarchy of needs is one of psychology's genuinely good ideas and has had a sustained impact in and out of psychology. The revision of the hierarchy by Kenrick, Griskevicius, Neuberg, and Schaller (2010, this issue) is overdue and makes an important contribution by grounding the hierarchy in modern evolutionary thought. However, we suggest that it may be premature to remove self-actualization from the hierarchy by reducing it to other needs associated with status and reproduction.

    This article develops a theoretical framework for biopolitical science as a science of political animals. This science moves through three levels of deep political history: the universal political history of the species, the cultural political history of the group, and the individual political history of animals in the group. To illustrate the particular application of biopolitical science, this essay shows how this science would help us to understand Abraham Lincoln's Emancipation Proclamation of January 1, 1863.

  5. Pre-acceleration from Landau-Lifshitz series

    The Landau-Lifshitz equation is considered as an approximation of the Abraham-Lorentz-Dirac equation. It is derived from the Abraham-Lorentz-Dirac equation by treating radiation reaction terms as a perturbation. However, while the Abraham-Lorentz-Dirac equation has pathological solutions of pre-acceleration and runaway, the Landau-Lifshitz equation and its finite higher-order extensions are free of these problems. So it seems mysterious that the properties of the solutions of these two equations are so different. In this paper we show that the problems of pre-acceleration and runaway appear when one considers a series of all-order perturbation which we call the Landau-Lifshitz series. We show that the Landau-Lifshitz series diverges in general. Hence a resummation is necessary to obtain a well-defined solution from the Landau-Lifshitz series. This resummation leads the pre-accelerating and the runaway solutions. The analysis focuses on the non-relativistic case, but we can extend the results obtained here to the relativistic case, at least in one dimension.

    We present a numerical study of the critical wetting behavior of an Ising magnet confined between two walls, separated by a distance L, where short-range inhomogeneous surface magnetic fields act. So, samples are assumed to have a size L × M, L being the width and M the length, respectively. By considering surface fields varying spatially with a given wavelength or period (λ), H1(x,λ) with 1 ≤ x ≤ M, we found that the wetting temperature is given by the exact result of Abraham [D.B. Abraham, Phys. Rev. Lett. 44, 1165 (1980)] provided that an effective field given by the spacial average[-3.4mm] value (Heff ≡ 1/λ ƒ0 λH1(x,λ)dx > 0) is considered. The above results hold in the low wavelength regime, while for λ → ∞ and a bivaluated surface field (i.e., Hmax for x ≤ M/ 2, and δHmax for x>M/ 2, with 0 <δ< 1), one observes two almost independent wetting transitions, both being compatible with Abraham's exact results corresponding to Hmax and δHmax, respectively. On the other hand, for H1(x,λ) ≠ 0 but Heff = 0 bulk standard critical behavior results is observed.

    We describe a novel multihealth system pediatric pharmacy residency program through the Ernest Mario School of Pharmacy at Rutgers University. Pediatric clinical pharmacy is a growing field that has seen an increase in demand for practitioners. Practice sites include freestanding children's hospitals, children's hospitals within adult hospitals, and pediatric units within adult hospitals. To accommodate a residency program in a region with no freestanding children's hospital, the pediatric faculty members at the Ernest Mario School of Pharmacy at Rutgers University developed a multihealth system postgraduate year 2 (PGY2) pediatric pharmacy residency program with 6 pediatric faculty members functioning as preceptors at their 5 respective practice sites. The multihealth system setup of the program provides the resident exposure to a multitude of patient populations, pediatric specialties, and pediatric pharmacy practices. In addition, the affiliation with Rutgers University allows an emphasis on academia with opportunities for the resident to lecture in small and large classrooms, facilitate discussion periods, assist with clinical laboratory classes, and precept pharmacy students. The resident has the unique opportunity to develop a research project with a large and diverse patient population owing to the multihealth system rotation sites. A multihealth system PGY2 residency in pediatric pharmacy provides the resident a well-rounded experience in pediatric clinical practice, research, and academia that will enhance the resident's ability to build his or her own pediatric pharmacy practice.

    The present study examined whether emotionally congruent facial muscular activation - a somatic index of emotional language embodiment can be elicited by reading subject-verb sentences composed of action verbs, that refer directly to facial expressions (e.g., Mario smiles), but also by reading more abstract state verbs, which provide more direct access to the emotions felt by the agent (e.g., Mario enjoys). To address this issue, we measured facial electromyography (EMG) while participants evaluated state and action verb sentences. We found emotional sentences including both verb categories to have valence-congruent effects on emotional ratings and corresponding facial muscle activations. As expected, state verb-sentences were judged with higher valence ratings than action verb-sentences. Moreover, despite emotional congruent facial activations were similar for the two linguistic categories, in a late temporal window we found a tendency for greater EMG modulation when reading action relative to state verb sentences. These results support embodied theories of language comprehension and suggest that understanding emotional action and state verb sentences relies on partially dissociable motor and emotional processes.

    2006-04-01

    The late Abraham Pais wrote the definitive biography of Albert Einstein, "Subtle is the Lord," which won an American Book Award. As a distinguished physicist and Einstein's colleague, Pais combined a sophisticated understanding of physics with first-hand knowledge of this notoriously private individual, offering rare insights into both. It is his unique double perspective that makes his work so valuable. Now Abraham Pais offers an illuminating portrait of another eminent colleague, J. Robert Oppenheimer, one of the most charismatic and enigmatic figures of modern physics. Pais introduces us to a precocious youth who sped through Harvard in three years, made signal contributions to quantum mechanics while in his twenties, and was instrumental in the growth of American physics in the decade before the Second World War, almost single-handedly putting American physics on the map. Pais paints a revealing portrait of Oppenheimer's life in Los Alamos, where in twenty remarkable, feverish months, under his inspired leadership, the first atomic bomb was designed and built, a success that made Oppenheimer America's most famous scientist. Pais, who was his next-door neighbor for many years, describes Oppenheimer's long tenure as Director of the Institute of Advanced Study at Princeton, but also shows how Oppenheimer's intensity and arrogance won him powerful enemies, who would ultimately make him one of the principal victims of the Red Scare of the 1950s. Told with compassion and deep insight, J. Robert Oppenheimer is the most comprehensive biography of the great physicist available. It is Abraham Pais's final work, completed after his death by Robert P. Crease, an acclaimed historian of science in his own right.

  4. Physics of electromagnetic and material stresses in optical manipulation

    2015-08-01

    Modeling the dynamics of optical manipulation experiments relies upon a precise mathematical representation of electromagnetic fields and the interpretation of optical momentum and stresses in materials. However, the momentum of light within media has been an issue of debate over the past century. Multiple energy-momentum models have been advanced, each, under certain conditions, agreeing with experimental observation and mathematically consistent with classical electromagnetism. The modern view is that the various formulations of electrodynamics represent different divisions of the total energy-momentum tensor, with the separation of field and matter being ambiguous. Recently, a proposed view of photon momentum identified two leading forms as the kinetic and canonical momenta. The Abraham momentum is responsible for the overall center-of-mass translation of a material, while the Minkowski momentum is responsible for translations with respect to the surrounding medium. However, the Abraham momentum corresponds to multiple, unique electromagnetic energy-momentum tensors that attempt to separate field from material responses (e.g. Abraham, Chu, and Einstein-Laub). However, only the form of the kinetic momentum density has been revealed, while the formulation that uniquely separates the kinetic stress tensor has remained ambiguous. In this correspondence, multiple formulations are considered within the framework of relativistic electrodynamics. We apply various mathematical techniques to identify the kinetic subsystem of electrodynamics. While optical manipulation is usually modeled using a stationary medium approximation, the lessons from relativistic electrodynamics reveal a specific distribution of electromagnetic stress in media. The physics of optical and static manipulation of dielectric particles are described within this framework.

    The environmental fate of engineered nanoparticles is controlled their colloidal stability and their interaction with different environmental surfaces. Little is known about sorption of nanoparticles to environmental surfaces under quasi-equilibrium conditions. Nevertheless, sorption isotherms may also be a valuable means of studying nanoparticle-sorbent interactions. We investigated sorption of engineered silver nanoparticles (nAg) from stable and unstable suspensions in presence and absence of natural organic matter (NOM) to model surfaces (sorbents with specific chemical functional groups) and environmental materials (plant leaves and sand). Morphology and nanomechanical parameters of the surfaces covered with nanoparticles were assessed using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The sorption of nAg from stable suspensions and in absence of NOM was non-linear and best described by a Langmuir model, where Langmuir coefficients varied with sorbent surface chemistry, which suggests monolayer sorption (Abraham et al. 2013). For nAg sorption from an unstable suspension, the sorption isotherms did not follow any classical sorption models, suggesting interplay between aggregation and sorption (Abraham et al. 2013). In contrast, sorption was strongly suppressed and exhibited linear sorption isotherms in the presence of NOM. The difference in sorption isotherms suggests predominance of different sorption mechanisms depending on presence or absence of NOM, which can be only partly explained by the NOM coating alone. On the basis of the current results, a partial release of NOM coating for sorption of certain surfaces cannot be excluded. The validity of the Langmuir isotherm suggests monolayer sorption, which can be explained by the blocking effect due to electrostatic repulsion of individual nanoparticles. In unstable suspensions, aggregates are instead formed in suspension, formed on the surface and then sorbed, or formed in both ways

    Consensus on a single electrodynamic theory has yet to be reached. Discord was seeded over a century ago when Abraham and Minkowski proposed different forms of electromagnetic momentum density and has since expanded in scope with the gradual introduction of other forms of momentum and force densities. Although degenerate sets of electrodynamic postulates can be fashioned to comply with global energy and momentum conservation, hope remains to isolate a single theory based on detailed comparison between force density predictions and radiation pressure experiments. This comparison is two-fold challenging because there are just a handful of quantitative radiation pressure measurements over the past century and the solutions developed from different postulates, which consist of approximate expressions and inferential deductions, are scattered throughout the literature. For these reasons, it is appropriate to conduct a consolidated and comprehensive re-analysis of past experiments under the assumption that the momentum and energy of light in matter are degenerate. We create a combined electrodynamic/fluid dynamic simulation testbed that uses five historically significant sets of electrodynamic postulates, including those by Abraham and Minkowski, to model radiation pressure under diverse configurations with minimal assumptions. This leads to new interpretations of landmark investigations of light momentum, including the Balazs thought experiment, the Jones-Richards and Jones-Leslie measurements of radiation pressure on submerged mirrors, observations of laser-deformed fluid surfaces, and experiments on optical trapping and tractor beaming of dielectric particles. We discuss the merits and demerits of each set of postulates when compared to available experimental evidence and fundamental conservation laws. Of the five sets of postulates, the Abraham and Einstein-Laub postulates provide the greatest consistency with observations and the most physically plausible

  8. Subsystem approach to the electrodynamics in dielectric fluids

    2012-10-01

    A century has now passed since the origins of the Abraham-Minkowski controversy pertaining to the correct form of optical momentum in media. Since, the debate has come to reference the general debate over optical momentum, including a number of competing formulations. The pervasive modern view is that the Abraham momentum represents the optical momentum contained within the fields and the Minkowski momentum includes a material component which is coupled with the fields. A recently proposed resolution to the debate identified Abraham's kinetic momentum as responsible for the overall center-of-mass translations of a medium and Minkowski's canonical momentum as responsible for local translations of a medium within or with respect to another medium. Still, current literature reveals significant confusion as to how systems of light and matter should be modeled as to deduce the equations of motion when multiple material types are present. For example, the state-of-the-art model for optical dynamics of submerged particles assumes over damped systems such that the mass of the particles is ignored in the equations of motion. In this paper, we apply the subsystem approach to deduce the electrodynamics of such systems. We show that regardless of which electromagnetic momentum continuity law is applied, the equations of motion can be correctly deduced as long as the continuity law is consistent with Maxwells equations and the overall system is closed such that momentum is conserved. Because the closed system includes the material response, the model can be very complex. However, we demonstrate with simple, well-known examples.

    By means of the time-dependent density-matrix renormalization-group (TDMRG) method we are able to follow the real-time dynamics of a single impurity embedded in a one-dimensional bath of interacting bosons. We focus on the impurity breathing mode, which is found to be well described by a single oscillation frequency and a damping rate. If the impurity is very weakly coupled to the bath, a Luttinger-liquid description is valid and the impurity suffers an Abraham-Lorentz radiation-reaction friction. For a large portion of the explored parameter space, the TDMRG results fall well beyond the Luttinger-liquid paradigm. PMID:23383804

    In 1943, Abraham Maslow, the "father of humanistic psychology," formulated his "Hierarchy of Needs Theory." Maslow proposed people have needs that must be satisfied, and these needs will motivate until they are satisfied. The needs are arranged in a hierarchy or pyramid ranging from basic needs to higher needs with an individual needing to satisfy a lower need before a higher need can motivate. The five needs of the hierarchy are: physiological needs, safety needs, social needs, esteem needs, and self-actualization. This article discusses adaptation of the hierarchy of needs to the dental practice to motivate staff to perform at a higher level.

    Ethical dilemmas pervade modern geriatric medicine. What is considered right or wrong will differ depending on, among other things, the patient's religion. The three Abrahamic monotheistic religions, Judaism, Christianity (its Catholic variant), and Islam all have carefully considered positions on medical ethics. Although much is held in common, there are significant differences. The authors present three clinical cases, each of which presents ethical dilemmas typical of geriatric care, especially at the end of life. On the basis of these scenarios, the normative ethical position of each religion is compared and contrasted. It is hoped that this approach will offer the geriatrician a useful approach to treating patients in an increasingly multicultural society.

  14. Movement of a millimeter-sized oil drop pushed by optical force

    We show experimentally that when an unfocused continuous wave (CW) laser beam is obliquely incident onto the surface of a millimeter-sized mineral oil drop on sucrose solution, it will exert a pushing force on the oil drop, making it move forwards along the surface of the sucrose solution. However, after a period of time, the oil drop stops moving. This can be explained as the phenomenon caused by the change of Abraham momentum, the optical gradient force, and friction together.

  15. Orbicular granite near Jelenia Góra in southwestern Poland: the first outcrops?

    NASA Astrophysics Data System (ADS)

    Kennan, Pádhraig S.; Lorenc, Marek W.

    2008-01-01

    In 1802, Leopold von Buch described some outcrops of orbicular granite in the Karkonosze granite, Lower Silesia, Poland. In that publication, Abraham Gottlieb Werner wrote a foreword dated 1800. The Silesian discovery predates that of the well-known orbicular diorite (Napoleonite) in outcrop on Corsica and, thus, may be the first ever record of this distinctive rock type in its geological context. The characterizing, closely-packed, simple orbs comprise K-feldspar cores surrounded by rims of radiating K-feldspar and quartz. Rapid growth from a hydrous, pegmatitic melt is indicated. The Karkonosze outcrop, in the timing of its discovery, is a unique part of the geological heritage.

  16. Finite Size Corrections to the Radiation Reaction Force in Classical Electrodynamics

    2010-08-27

    We introduce an effective field theory approach that describes the motion of finite size objects under the influence of electromagnetic fields. We prove that leading order effects due to the finite radius R of a spherically symmetric charge is order R{sup 2} rather than order R in any physical model, as widely claimed in the literature. This scaling arises as a consequence of Poincare and gauge symmetries, which can be shown to exclude linear corrections. We use the formalism to calculate the leading order finite size correction to the Abraham-Lorentz-Dirac force.

    2014-04-01

    From the development of the electron theory by H. A. Lorentz in 1906, many authors have tried to reformulate this model. P. A. M. Dirac derived the relativistic-classical electron model in 1938, which is now called the Lorentz-Abraham-Dirac model. But this model has the big difficulty of the runaway solution. Recently, this equation has become important for ultra-intense laser-electron (plasma) interactions. For simulations in this research field, it is desirable to stabilize this model of the radiation reaction. In this paper, we will discuss this ability for radiation reaction with the inclusion of vacuum polarization.

    The previously proposed three-dimensional soliton model of a photon propagating in vacuum is modified to describe its propagation in a homogeneous linear dielectric medium. The one-soliton solution of the derived nonlinear equation correctly predicts the energy and the Abraham and Minkowski momenta of the photon in dielectrics. A new nonlinear equation is proposed, which has a one-soliton solution that at every point oscillates with the same frequency and falls exponentially in the longitudinal, as well as in the transverse direction from the centre of the soliton.

    2013-05-01

    We develop a new fluid model of a warm plasma that includes the radiative self-force on each plasma electron. Our approach is a natural generalization of established methods for generating fluid models without radiation reaction. The equilibrium of a magnetized plasma is analysed, and it is shown that the thermal motion is confined to the magnetic field lines. A dispersion relation is deduced for electric waves in a magnetized plasma, and it is shown to agree with our recently established relativistic kinetic theory derived from the Lorentz-Abraham-Dirac equation.

    2014-04-01

    A number of capillary columns with stationary liquid phases based on mono- and dication pyridinium ionic liquids (ILs) were prepared. Their polarity was evaluated using McReynolds system and the selectivity was estimated from intermolecular interactions. The parameters of intermolecular interactions were obtained from retention data using the (Abraham) model of the linear free energy relationship. The dependences of intermolecular interactions on the structure of the cation in the ILs under study were revealed. The results were compared with the data for the traditional phases (HP-5, ZB-WAX). Examples of separation of mixtures of oxygen-containing compounds on the phases under study are given.

We calculated density profiles and adsorption coefficients using Percus-Yevick and soft mean spherical associative approximations. The results are compared with Monte Carlo simulation data. It is shown that at higher temperatures both approximations satisfactory reproduce the simulation data. For lower temperatures, soft mean spherical approximation gives good agreement at low and at high densities while in at mid range densities, the prediction is only qualitative. The formation of a depletion layer between water and hydrophobic surface was also demonstrated and studied.

    2000-01-01

    The purpose of this research is to explore the relationships between self-image and personality characteristics with cognitive impairment in an isolated group during wintering. Cognitive performance is measured with the Stres Battery (SB), self-image by Abraham's Matrix of Intra- and Inter-Processes in Groups (MIPG), and interpersonal characteristics by the usual personality inventories. Results show that good cognitive performances are related to discordances between the real self and the ideal self and that bad performances are related to harmony between these two images. Moreover, the best cognitive performers have low scores in extroversion and assertiveness. The results are discussed in terms of specific adaptive reactions to wintering.

    Phorbol diesters are tumor-promoting agents that cause differentiation of HL60 human leukemic cells and concomitantly alter surface transferrin-receptor expression [Rovera, G., Ferreo, D., Pagliardi, G. L., Vartikar, J., Pessano, S., Bottero, L., Abraham, S. & Lebman, D. (1982) Ann. N.Y. Acad. Sci. 397, 211-220]. Transferrin-receptor regulation is shown here to result from a rapid and reversible internalization process that is temporally associated with reversible increased phosphorylation (hyperphosphorylation) of the transferrin receptor. Such a reversible mechanism involving regulation of these surface proteins could result in the rapid generation of an early signal for HL60 cellular differentiation. Images PMID:6326098

    This text tries to understand the Nursing team and their (dis)satisfactions in the work. We consider the association with the theory of basic human needs of Abraham Maslow as a way to systemize and to comprehend the recurrent situations and the day-by-day Nursing issues. The necessities are structuralized hierarchically in physiological, security, social, auto-esteem and auto-accomplishment indicating the degree of satisfaction (from the disease to the fullness) of an individual or group. The advantage of this approach consists of being able to use the solid, depth and rich Maslow theory in concrete and particular situations of the Nursing team. PMID:17340737

    Shortly after President Abraham Lincoln's assassin was killed on April 26, 1865, a formal inquest was held to positively identify the body. Dr. John Frederick May, a leading surgeon in the District of Columbia, was summoned to examine the remains. Two years earlier, Dr. May had removed a fibroid tumor from the back of the assassin's neck and an identifiable large ugly scar resulted when the wound inadvertently opened and healed by granulation. Based upon the recognition of the scar made by his scalpel, Dr. May made a positive identification. PMID:9793835

    The Feynman Disk experiment and a related thought experiment with a static magnetic field and capacitor are studied. The mechanical torque integrated over time (angular impulse) is related to the angular momentum in the electric/magnetic field. This is not called an electromagnetic field since quasi-static as well as electromagnetic effects are included. The angular momentum in the electric/magnetic field is examined to determine its static and radiative components. This comparison was then examined to see if it clarified the Abraham-Minkowski paradox.

    Quality management professionals confront the challenge of motivating others to participate in the improvement of patient care. Producing this motivation frequently proves problematic. This article addresses the issue of motivation by presenting it as a process. Abraham Maslow's hierarchy of needs functions as the foundation of the process. A process model is used to demonstrate that satisfaction of the higher-level needs of esteem and self-actualization is required to produce true motivation. By understanding the process of motivation, we may become more effective in improving patient care.

    We extend de la Fuente and Romero's (Gen Relativ Gravit 47:33, 2015) defining equation for uniform acceleration in a general curved spacetime from linear acceleration to the full Lorentz covariant uniform acceleration. In a flat spacetime background, we have explicit solutions. We use generalized Fermi-Walker transport to parallel transport the Frenet basis along the trajectory. In flat spacetime, we obtain velocity and acceleration transformations from a uniformly accelerated system to an inertial system. We obtain the time dilation between accelerated clocks. We apply our acceleration transformations to the motion of a charged particle in a constant electromagnetic field and recover the Lorentz-Abraham-Dirac equation.

    This paper attempts to draw analogies between the Sabbath and certain mental health interventions. These interventions are derived from a family centered education program developed by the author for teachers and student and related to social group work. Five interventions characterizing this program were extracted and compared with Abraham Joshua Heschel's philosophy of the Sabbath: simulation, here-and-now emphasis, private reflection, emphasis on process, and positive feedback. The author concludes that both the Sabbath and family centered education oriented interventions should reinforce a deeper understanding and appreciation of one another.

    We derive radiation reaction from QED in a strong background field. We identify, in general, the diagrams and processes contributing to recoil effects in the average momentum of a scattered electron, using perturbation theory in the Furry picture: we work to lowest nontrivial order in α. For the explicit example of scattering in a plane wave background, we compare QED with classical electrodynamics in the limit ℏ → 0, finding agreement with the Lorentz-Abraham-Dirac and Landau-Lifshitz equations, and with Larmor's formula. The first quantum corrections are also presented.

    During an 1857 trial, the defence claimed that the accused should be absolved of wilful murder because an overdose of chloroform during surgery induced insanity. In a rare appearance as a prosecutor, Abraham Lincoln tried the case for the State of Illinois. Expert medical witnesses testified about the side effects of chloroform and chloroform-induced insanity. Significantly, Lincoln was not knowledgeable about medical jurisprudence and overlooked potential sources of evidence and expert witnesses. Defence lawyers presented an impressive array of physicians to testify about insanity, about chloroform and about the results of an overdosage during anaesthesia. Considering the state of scientific knowledge at the time, the trial was notable.

    With the introduction of Nintendo video-games on a large scale, reports of children having seizures while playing suggested a possible specific, provocative factor. Although 50% of the photosensitive patients are also sensitive to a 50-Hz television, nonphotosensitive patients with a history of video-game seizures were described as well. The question arises whether this is a mere coincidence, provoked by fatigue and stress, is related to the reaction to the television screen itself, or depends on the movement and color of the pictures of this specific game. A European study was performed in four countries and five sites. All patients were selected because of a history of television, video- or computer-game seizures, with a history of sun-light-, discotheque-, or black and white pattern-evoked seizures, or were already known to be sensitive to intermittent photic stimulation. A total of 387 patients were investigated; 220 (75%) were female and 214 (55%) of those were < 18 years of age. After a routine examination, intermittent photic, pattern, and television stimulation were performed in a standardized way. The patients were investigated with Super Mario World and a standard relatively nonprovocative TV program, both on a 50- and 100-Hz television. Regardless of the distance, Super Mario World proved to be more provocative than the standard program (Wilcoxon, p < 0.05). Eighty-five percent showed epileptiform discharges evoked by intermittent photic stimulation. Forty-five percent of patients were 50-Hz television sensitive and 26% were 100-Hz television sensitive. Pattern sensitivity was found in 28% of patients. The patients, referred because of a television, video- or computer-game seizure, were significantly more sensitive to pattern and to the 50-Hz television (chi square, p < 0.001).

  8. A very general rate expression for charge hopping in semiconducting polymers

    SciTech Connect

    Fornari, Rocco P.; Aragó, Juan; Troisi, Alessandro

    2015-05-14

    We propose an expression of the hopping rate between localized states in semiconducting disordered polymers that contain the most used rates in the literature as special cases. We stress that these rates cannot be obtained directly from electron transfer rate theories as it is not possible to define diabatic localized states if the localization is caused by disorder, as in most polymers, rather than nuclear polarization effects. After defining the separate classes of accepting and inducing nuclear modes in the system, we obtain a general expression of the hopping rate. We show that, under the appropriate limits, this expression reduces to (i) a single-phonon rate expression or (ii) the Miller-Abrahams rate or (iii) a multi-phonon expression. The description of these limits from a more general expression is useful to interpolate between them, to validate the assumptions of each limiting case, and to define the simplest rate expression that still captures the main features of the charge transport. When the rate expression is fed with a range of realistic parameters the deviation from the Miller-Abrahams rate is large or extremely large, especially for hopping toward lower energy states, due to the energy gap law.

It is shown that the results given in § 75 of the book Electrodynamics of Continuous Media by L D Landau and E M Lifshitz (Moscow: Nauka, 1982, in Russian) and in § 105 of the book Fundamentals of the Theory of Electricity by I E Tamm (Moscow: Nauka, 1989, in Russian) unambiguously follow only from the Maxwell equations of macroscopic electrodynamics, the corresponding constitutive equations, and the equations of motion of a substance (the hydrodynamic equations). These results are as follows: (1) the force acting on a unit volume of a motionless substance is given by the sum of the Helmholtz force and the Abraham force; (2) the momentum density of an electromagnetic field is the Umov-Poynting vector divided by c2, and (3) the stress tensor related to the field coincides in its form with the sum of the stress tensor of the electrostatic field and the stress tensor of the magnetostatic field. Thus, it is proved that the symmetric form of the Abraham tensor stands for the energy-momentum tensor of an electromagnetic field in a motionless medium.

    2007-05-01

    The late Abraham Pais, author of the award winning biography of Albert Einstein, Subtle is the Lord , here offers an illuminating portrait of another of his eminent colleagues, J. Robert Oppenheimer, one of the most charismatic and enigmatic figures of modern physics. Pais introduces us to a precocious youth who sped through Harvard in three years, made signal contributions to quantum mechanics while in his twenties, and was instrumental in the growth of American physics in the decade before the Second World War, almost single-handedly bringing it to a state of prominence. He paints a revealing portrait of Oppenheimer's life in Los Alamos, where in twenty remarkable, feverish months, and under his inspired guidance, the first atomic bomb was designed and built, a success that made Oppenheimer America's most famous scientist. Pais describes Oppenheimer's long tenure as Director of the Institute of Advanced Study at Princeton, where the two men worked together closely. He shows not only Oppenheimer's brilliance and leadership, but also how his displays of intensity and arrogance won him powerful enemies, ones who would ultimately make him one of the principal victims of the Red Scare of the 1950s. J. Robert Oppenheimer is Abraham Pais's final work, completed after his death by Robert P. Crease, an acclaimed historian of science in his own right. Told with compassion and deep insight, it is the most comprehensive biography of the great physicist available. Anyone seeking an insider's portrait of this enigmatic man will find it indispensable.

    We propose an expression of the hopping rate between localized states in semiconducting disordered polymers that contain the most used rates in the literature as special cases. We stress that these rates cannot be obtained directly from electron transfer rate theories as it is not possible to define diabatic localized states if the localization is caused by disorder, as in most polymers, rather than nuclear polarization effects. After defining the separate classes of accepting and inducing nuclear modes in the system, we obtain a general expression of the hopping rate. We show that, under the appropriate limits, this expression reduces to (i) a single-phonon rate expression or (ii) the Miller-Abrahams rate or (iii) a multi-phonon expression. The description of these limits from a more general expression is useful to interpolate between them, to validate the assumptions of each limiting case, and to define the simplest rate expression that still captures the main features of the charge transport. When the rate expression is fed with a range of realistic parameters the deviation from the Miller-Abrahams rate is large or extremely large, especially for hopping toward lower energy states, due to the energy gap law.

    An ad hoc quantization scheme for the electromagnetic field in a weakly dispersive, transparent dielectric leads to the definition of canonical and kinetic forms for the momentum of the electromagnetic field in a dispersive medium. The canonical momentum is uniquely defined as the operator that generates spatial translations in a uniform medium, but the quantization scheme suggests two possible choices for the kinetic momentum operator, corresponding to the Abraham or the Minkowski momentum in classical electrodynamics. Another implication of this procedure is that a wave packet containing a single dressed photon travels at the group velocity through the medium. The physical significance of the canonical momentum has already been established by considerations of energy and momentum conservation in the atomic recoil due to spontaneous emission, the Cerenkov effect, the Doppler effect, and phase matching in nonlinear optical processes. In addition, the data of the Jones and Leslie radiation pressure experiment is consistent with the assignment of one ({Dirac_h}/2{pi})k unit of canonical momentum to each dressed photon. By contrast, experiments in which the dielectric is rigidly accelerated by unbalanced electromagnetic forces require the use of the Abraham momentum.

  13. Electromagnetic momentum and the energy-momentum tensor in a linear medium with magnetic and dielectric properties

    In a continuum setting, the energy-momentum tensor embodies the relations between conservation of energy, conservation of linear momentum, and conservation of angular momentum. The well-defined total energy and the well-defined total momentum in a thermodynamically closed system with complete equations of motion are used to construct the total energy-momentum tensor for a stationary simple linear material with both magnetic and dielectric properties illuminated by a quasimonochromatic pulse of light through a gradient-index antireflection coating. The perplexing issues surrounding the Abraham and Minkowski momentums are bypassed by working entirely with conservation principles, the total energy, and the total momentum. We derive electromagnetic continuity equations and equations of motion for the macroscopic fields based on the material four-divergence of the traceless, symmetric total energy-momentum tensor. We identify contradictions between the macroscopic Maxwell equations and the continuum form of the conservation principles. We resolve the contradictions, which are the actual fundamental issues underlying the Abraham-Minkowski controversy, by constructing a unified version of continuum electrodynamics that is based on establishing consistency between the three-dimensional Maxwell equations for macroscopic fields, the electromagnetic continuity equations, the four-divergence of the total energy-momentum tensor, and a four-dimensional tensor formulation of electrodynamics for macroscopic fields in a simple linear medium.

  14. Efficient Algorithms for the Two-Dimensional Ising Model with a Surface Field

    The bond propagation and site propagation algorithms are extended to the two-dimensional (2D) Ising model with a surface field. With these algorithms we can calculate the free energy, internal energy, specific heat, magnetization, correlation functions, surface magnetization, surface susceptibility and surface correlations. The method can handle continuous and discrete bond and surface-field disorder and is especially efficient in the case of bond or site dilution. To test these algorithms, we study the wetting transition of the 2D Ising model, which was solved exactly by Abraham. We can locate the transition point accurately with a relative error of . We carry out the calculation of the specific heat and surface susceptibility on lattices with sizes up to . The results show that a finite jump develops in the specific heat and surface susceptibility at the transition point as the lattice size increases. For lattice size the parallel correlation length exponent is , while Abraham's exact result is . The perpendicular correlation length exponent for lattice size is , whereas its exact value is.

    We study the relation between the energy-momentum tensor of the electromagnetic field and the group velocity of quasi-monochromatic waves in a nonabsorptive, isotropic, spatially and temporally dispersive dielectric. It is shown that the Abraham force acting on a dielectric is not needed for the momentum conservation law to hold if the dielectric is free of external charges and currents and if the Abraham momentum density is used. The energy-momentum tensor turns out to be symmetric, and the Maxwell stress tensor is expressed either in terms of the momentum density vector and the group velocity or in terms of the energy density and the group velocity. The stress tensor and the energy density are essentially dependent on the frequency and wave vector derivatives of the functions that describe the electromagnetic properties of the medium (i.e., the dielectric permittivity and the magnetic permeability). The obtained results are applicable to both ordinary and left-handed media. The results are compared with those of other authors. The pressure a wave exerts on the interface between two media is calculated. For both ordinary and left-handed media, either 'radiation pressure' or 'radiation attraction' can occur at the interface, depending on the material parameters of the two media. For liquid dielectrics, the striction effect is considered.

  16. Equation of motion with radiation reaction in ultrarelativistic laser-electron interactions

    The intensity of the ultra-short pulse lasers has reached 10{sup 22} W/cm{sup 2} owing to the advancements of laser technology. When the motion of an electron becomes relativistic, bremsstrahlung accompanies it. The energy from this bremsstrahlung corresponds to the energy loss of the electron; therefore, the motion of the electron deviates from the case without radiation. The radiation behaves something like resistance. This effect called ''radiation reaction'' or ''radiation damping'' and the force converted from the radiation is named the ''radiation reaction force'' or the ''damping force''. The equation of motion with the reaction force is known as the Lorentz-Abraham-Dirac (LAD) equation, but the solution of this equation is not physical due to the fact that it has a ''run-away'' solution. As one solution of this problem, we have derived a new equation which takes the place of the Lorentz-Abraham-Dirac equation. We will show the validity of this equation with a simple theoretical analysis.

  17. Non-Markovian Quantum Friction of Bright Solitons in Superfluids

    NASA Astrophysics Data System (ADS)

    Efimkin, Dmitry K.; Hofmann, Johannes; Galitski, Victor

    2016-06-01

    We explore the quantum dynamics of a bright matter-wave soliton in a quasi-one-dimensional bosonic superfluid with attractive interactions. Specifically, we focus on the dissipative forces experienced by the soliton due to its interaction with Bogoliubov excitations. Using the collective coordinate approach and the Keldysh formalism, a Langevin equation of motion for the soliton is derived from first principles. The equation contains a stochastic Langevin force (associated with quantum noise) and a nonlocal in time dissipative force, which appears due to inelastic scattering of Bogoliubov quasiparticles off of the moving soliton. It is shown that Ohmic friction (i.e., a term proportional to the soliton's velocity) is absent in the integrable setup. However, the Markovian approximation gives rise to the Abraham-Lorentz force (i.e., a term proportional to the derivative of the soliton's acceleration), which is known from classical electrodynamics of a charged particle interacting with its own radiation. These Abraham-Lorentz equations famously contain a fundamental causality paradox, where the soliton (particle) interacts with excitations (radiation) originating from future events. We show, however, that the causality paradox is an artifact of the Markovian approximation, and our exact non-Markovian dissipative equations give rise to physical trajectories. We argue that the quantum friction discussed here should be observable in current quantum gas experiments.

    The formative period of Latin and Hebrew astrology occurred virtually simultaneously in both cultures. In the second quarter of the twelfth century the terminology of the subject was established and the textbooks which became authoritative were written. The responsibility for this lay almost entirely with two scholars: John of Seville for the Latins, and Abraham ibn Ezra for the Jews. It is unlikely to have been by coincidence that the same developments in astrology occurred in these two cultures. John of Seville and Abraham ibn Ezra were both brought up within the Islamic culture of Spain, and their astrology was Arabic astrology. Moreover, some scholars have thought that John's origins were Jewish, while Ibn Ezra is known to have collaborated with Latin scholars (whose names are not recorded). It cannot be a coincidence that they forged the science of astrology for their respect co-religionists at almost the same time. Yet, very little research has been done on the possible relations between the two scholars. The purpose of this paper is to begin to explore this relationship, and to illustrate it in particular by their shared doctrine concern the location of pain.

    We propose a set of postulates to describe the mechanical interaction between a plane-wave electromagnetic pulse and a dispersive, dissipative slab having a refractive index of arbitrary sign. The postulates include the Abraham electromagnetic momentum density, a generalized Lorentz force law, and a model for absorption-driven mass transfer from the pulse to the medium. These opto-mechanical mechanisms are incorporated into a one-dimensional finite-difference time-domain algorithm that solves Maxwell's equations and calculates the instantaneous force densities exerted by the pulse onto the slab, the momentum-per-unit-area of the pulse and slab, and the trajectories of the slab and system center-of-mass. We show that the postulates are consistent with conservation of global energy, momentum, and center-of-mass velocity at all times, even for cases in which the refractive index of the slab is negative or zero. Consistency between the set of postulates and well-established conservation laws reinforces the Abraham momentum density as the one true electromagnetic momentum density and enables, for the first time, identification of the correct form of the electromagnetic mass density distribution and development of an explicit model for mass transfer due to absorption, for the most general case of a ponderable medium that is both dispersive and dissipative.

  1. Electromagnetic force and torque in ponderable media.

    PubMed

    Mansuripur, Masud

    2008-09-15

    Maxwell's macroscopic equations combined with a generalized form of the Lorentz law of force are a complete and consistent set of equations. Not only are these five equations fully compatible with special relativity, they also conform with conservation laws of energy, momentum, and angular momentum. We demonstrate consistency with the conservation laws by showing that, when a beam of light enters a magnetic dielectric, a fraction of the incident linear (or angular) momentum pours into the medium at a rate determined by the Abraham momentum density, E x H/c(2), and the group velocity V(g) of the electromagnetic field. The balance of the incident, reflected, and transmitted momenta is subsequently transferred to the medium as force (or torque) at the leading edge of the beam, which propagates through the medium with velocity V(g). Our analysis does not require "hidden" momenta to comply with the conservation laws, nor does it dissolve into ambiguities with regard to the nature of electromagnetic momentum in ponderable media. The linear and angular momenta of the electromagnetic field are clearly associated with the Abraham momentum, and the phase and group refractive indices (n(p) and n(g)) play distinct yet definitive roles in the expressions of force, torque, and momentum densities.

    The retention factors of neutral, positively charged, and negatively charged solutes were determined in a liposome electrokinetic chromatography (EKC) system, where cerasome was used as the investigated liposome. The Abraham linear free energy relationship (LFER) for neutral and ionized solutes gave a good account of the retention factors (N = 71, R(2) = 0.814, and SD = 0.29 log units). It was shown that the calculated retention factors for 16 neutral acids were about four times higher than those of the corresponding anions, whereas the calculated retention factors for neutral bases were less than those for the corresponding cations by a factor of 0.36. The LFER equation for neutral species, anions, and cations was compared with those for partition from water into a number of solvents and for n-octanol-water distribution coefficients. It was shown that the cerasome EKC system is substantially different to the other systems and consequently it could be a very useful additional model system, possibly for predicting skin permeation. It was further shown that there are considerable advantages in the use of Abraham LFERs that can encompass not only neutral molecules but also ionic species.

    A year after Mario Monicelli's suicide, the death of another famous person in Italy, Lucio Magri, reawakened the Italian debate on social, ethical and juridical issues in end-of-life decisions. Unlike Monicelli, Lucio Magri decided to end his own life in Switzerland with the help of a physician because his mental illness rendered his life unbearable. Both Monicelli and Magri suffered from a severe depression. The authors analyze the ethical issues regarding the right to die for mentally ill patients and neurological disabled patients, discussing the decision-making autonomy in persons suffering from severe depression. The role of the psychiatry in the management of end-of-life decision requests is considered along with pros and cons of suicide prevention and rationale suicide.

    Plasmonics is one of the growing fields in modern photonics that has garnered increasing interest over the last few years. In this focus issue, the specific challenges concerning terahertz plasmonics have been addressed and most recent advances in this specific field have been highlighted. The articles demonstrate the diversity and the opportunities of this rich field by covering a variety of topics ranging from the propagation of surface plasmon polaritons (SPPs) on artificially structures surfaces, 2D manipulation of surface plasmons and SPPs, plasmonic focusing, plasmonic high-Q resonators for sensing applications, plasmonically enhanced terahertz antennas to terahertz field manipulation by use of plasmonic structures. The articles substantiate the impact of plasmonics and its great innovative potential for terahertz technology. In memory of Professor Mario Sorolla Ayza.

    Inkatha Freedom Party MP Mario Oriani-Ambrosini's impassioned plea to legalise the medical use of cannabis must be understood in the context of his own condition as well as legislative changes in at least ten countries. This article argues that any decisions to shift policy must be based on a consideration of the evidence on the risks and benefits associated with the medical use of cannabis for the individual and broader society. It concludes that there are important gaps in the evidence base, particularly in human trials supporting the efficacy of cannabis use for treating and preventing medical conditions and alleviating negative symptoms associated with these conditions. South African researchers should be enabled actively to support development of the necessary evidence base actively by conducting preclinical and clinical research in this area. Human trials to establish the efficacy of the use of cannabis/cannabinoids in addressing AIDS wasting syndrome and other negative sequelae of HIV and AIDS are especially needed.

    On June 10, 2002, a unanimous US Supreme Court rejected the claim by Mario Echazabal that he had been denied his rights under the Americans with Disabilities Act when Chevron USA had refused to employ him because he had hepatitis C. Chevron believed that Echazabal’s exposure to hepatotoxic chemicals in its refinery would pose a grave risk to his health. This case poses critical questions about the ethics of public health: When, if ever, is paternalism justified? Must choice always trump other values? What ought to be the balance between welfare and liberty? Strikingly, the groups that came to Echazabal’s defense adopted an antipaternalistic posture fundamentally at odds with the ethical foundations of occupational health and safety policy.

    The social sciences rely on assumptions of a unified self for their explanatory logics. Recent work in the new multidisciplinary field of social neuroscience challenges precisely this unproblematic character of the subjective self as basic, well-defined entity. If disciplinary self-insulation is deemed unacceptable, the philosophical challenge arises of systematically bringing together neurological, psychological, sociological, and anthropological dimensions of analysis in one framework such as dynamic systems theory; and of finding bridging concepts such as memory, social cognition, and cultural scripts that can facilitate the cross disciplinary study of the reflexive self. Relying on the systemic philosophy of science developed by Mario Bunge, this paper takes some steps in this direction.

    STS-54 Mission Specialist (MS2) and extravehicular crewmember 1 (EV1) Gregory J. Harbaugh, wearing extravehicular mobility unit (EMU) (red stripes),carries EMU-suited MS1 and EV2 Mario Runco, Jr along Endeavour's, Orbiter Vehicle (OV) 105's, payload bay (PLB) starboard sill longeron during Detailed Test Objective (DTO) 1210, extravehicular activity (EVA) operations procedure/ training. Harbaugh uses Runco's EMU mini-workstation as a handhold. The objective of this exercise is to simulate carrying a large object. It will also evaluate the ability of an astronaut to move about it space with a 'bulky' object in hand. The empty airborne support equipment (ASE) frames appear below the crewmembers and the PLB aft bulkhead behind them. This EVA is the first in a series to broaden EVA procedures and training experience bases and proficiency in preparation for future EVAs such as the Hubble Space Telescope (HST) and Space Station Freedom (SSF).

    External Ion Beam Analysis is a useful tool for the characterization of cultural heritage objects. During the last decade, several significant collaborations have been established between Ion Beam Analysis (IBA) scientists and art or archeology professionals, demanding in-air IBA for a variety of different cultural heritage objects. In-air Particle Induced X-ray Emission (PIXE) analyses of an oil painting by the Italian painter, Mario Sironi, from the Museum of Contemporary Art of the University of São Paulo (MAC-USP), were examined. This painting is particularly interesting due to paintings on both sides (oil on canvas on the front and oil on wood on the back side). PIXE analysis helped the identification of the pigment similarities on both sides of the painting, suggesting the same authorship.
