  1. Ethnology in the metropole: Robert Knox, Robert Gordon Latham and local sites of observational training.

    PubMed

    Sera-Shriar, Efram

    2011-12-01

    Anthropologists have traditionally separated the history of their discipline into two main diverging methodological paradigms: nineteenth-century armchair theorizing, and twentieth-century field-based research. But this tradition obscures both the complexity of the observational practices of early nineteenth-century researchers and the high degree of continuity between these practices and the techniques that came later. While historians have long since abandoned the notion that nineteenth-century ethnologists and anthropologists were merely 'armchair' theorists, this paper shows that there is still much to learn once one asks more insistently what the observational practices of early researchers were actually like. By way of bringing out this complexity and continuity, this essay re-examines the work of two well-known British ethnologists, Robert Knox, and Robert Gordon Latham; looking in particular at their methods of observing, analysing and representing different racial groups. In the work of each figure, early training in natural history, anatomy and physiology can be seen to have influenced their observational practices when it came to identifying and classifying human varieties. Moreover, in both cases, Knox and Latham developed locally-based observational training sites.

  2. 'Robert Schumann's mental illnesses. (Genius and madness)', by Mlle Dr Pascal (1908a): Introduction and translation by Felicia Gordon.

    Dr Constance Pascal's study of Robert Schumann's mental illnesses, dating from the early years of the twentieth century, reflects contemporary theories on the relations between gifted individuals and mental illness: the genius vs. madness debate. Pascal's reading of Schumann's musical career, in conjunction with his mental profile, offers a sympathetic and nuanced overview of the composer and a critical perspective on extant theories of his illness.

    Pegrum, Colin; Campbell, Archie; Hampshire, Damian

    2013-07-01

    Gordon Donaldson died in Glasgow on 28 November 2012 at the age of 71. He was born in Edinburgh and brought up and educated in Glasgow, which was his home city for much of his life. He was educated first at Glasgow Academy, and then with a scholarship at Christ's College Cambridge. Here he read Natural Sciences, finishing with first class honors in Physics. He then did a PhD on tunneling in superconductors in the Mond Laboratory, supervised by John Adkins. These were interesting times, since type II superconductors had only recently been identified, and the Mond was a leading player in the physics of vortices and other quantum effects. It was headed by Pippard and Shoenberg, and colleagues around that time were Brian Josephson, John Clarke, Colin Gough and John Waldram. On finishing his PhD in 1966 Gordon went straight to a lectureship at the University of Lancaster. In 1975 during a sabbatical at the University of California, Berkeley, with John Clarke's group, Gordon co-invented thin-film gradiometers with integrated DC SQUIDs. He then moved back to Glasgow, to the Department of Applied Physics at Strathclyde University, where he founded a new research group to make and use superconducting devices, especially SQUIDs and gradiometers. From modest beginnings the group grew steadily, acquiring new facilities and members, until in the 1990s it had over 20 members and a host of collaborators from elsewhere in Glasgow and abroad. With funding from the Wellcome Trust, Gordon and colleagues at Glasgow University and the Southern General Hospital in Glasgow set up a new biomagnetism facility in 1998 on the hospital campus to use SQUID gradiometers made at Strathclyde for measurements on patients and volunteers. Another of his main research interests was the use of SQUIDs for nondestructive evaluation (NDE). This started in the days before high temperature superconductors (HTS) with wire-wound gradiometers and niobium SQUIDs, soon moving on to miniature thin-film niobium

    Margoulis, W

    1921-01-01

    The characteristics of the airplanes built for the Gordon Bennet Airplane Cup race that took place on September 28, 1920 are described. The airplanes are discussed from a aerodynamical point of view, with a number of new details concerning the French machines. Also discussed is the regulation of future races. The author argues that there should be no limitations on the power of the aircraft engines. He reasons that in the present state of things, liberty with regard to engine power does not lead to a search for the most powerful engine, but for one which is reliable and light, thus leading to progress.

    To present the personality of Bob Gilmore is a formidable task, as his scientific contributions include group theory, laser physics, non-linear dynamics, catastrophe theory, thermodynamics, dynamical systems, quantum theory and more. But even if we succeed in describing his contributions, much of Gilmore's being would be lost. Bob as advisor, Bob as father, Bob as teacher, Bob as scientific communicator reveal as much of Bob Gilmore as his scientific papers and his books. Very much as in the Group Theory so close to him, there is a Robert Gilmore in abstract as well as representations of Robert Gilmore. We will make an attempt to find the "principle of the rule", the abstract level of Robert Gilmore as well as Robert Gilmore, himself, as a representation of the duality science-humanism.

    1989-01-01

    C. Gordon Fullerton is a research pilot at NASA's Dryden Flight Research Center, Edwards, California. His assignments include a variety of flight research and support activities piloting NASA's B-52 launch aircraft, the 747 Shuttle Carrier Aircraft (SCA), and other multi-engine and high performance aircraft. Fullerton, who has logged 382 hours in space flight, was a NASA astronaut from September 1969 until November 1986 when he joined the Flight Crew Branch at Dryden. In July 1988, he completed a 30-year career with the U.S. Air Force and retired as a colonel. As the project pilot on the NASA B-52 launch aircraft, Fullerton flew during the first six air launches of the commercially developed Pegasus space vehicle. He was involved in a series of development air launches of the X-38 Crew Recovery Vehicle and in the Pegasus launch of the X-43A Hyper-X advanced propulsion project. Fullerton also flies Dryden's DC-8 Airborne Science aircraft, regularly deployed worldwide to support a variety of research studies, including atmospheric physics, ground mapping and meteorology. In addition to these current activities, Fullerton has been involved in numerous other research programs at Dryden. He was the project pilot on the Propulsion Controlled Aircraft program, during which he successfully landed both a modified F-15 and an MD-11 transport with all control surfaces neutralized, using only engine thrust modulation for control. Assigned to evaluate the flying qualities of the Russian Tu-144 supersonic transport during two flights in 1998, he reached a speed of Mach 2 and became one of only two non-Russian pilots to fly that aircraft. He piloted a Convair 990 modified to test space shuttle landing gear components during many very high-speed landings. Other projects for which he has flown in the past include the C-140 JetStar Laminar Flow Control; F-111 Mission Adaptive Wing; F-14 Variable Sweep Flow Transition; Space Shuttle drag chute and F-111 crew module parachute tests

    1994-01-01

    The Gordon Bell Prize recognizes significant achievements in the application of supercomputers to scientific and engineering problems. In 1993, finalists were named for work in three categories: (1) Performance, which recognizes those who solved a real problem in the quickest elapsed time. (2) Price/performance, which encourages the development of cost-effective supercomputing. (3) Compiler-generated speedup, which measures how well compiler writers are facilitating the programming of parallel processors. The winners were announced November 17 at the Supercomputing 93 conference in Portland, Oregon. Gordon Bell, an independent consultant in Los Altos, California, is sponsoring $2,000 in prizes each year for 10 years to promote practical parallel processing research. This is the sixth year of the prize, which Computer administers. Something unprecedented in Gordon Bell Prize competition occurred this year: A computer manufacturer was singled out for recognition. Nine entries reporting results obtained on the Cray C90 were received, seven of the submissions orchestrated by Cray Research. Although none of these entries showed sufficiently high performance to win outright, the judges were impressed by the breadth of applications that ran well on this machine, all nine running at more than a third of the peak performance of the machine.

  18. 'National Hero and Very Queer Fish': Empire, Sexuality and the British Remembrance of General Gordon, 1918-72.

    PubMed

    Jones, Max

    2015-01-01

    This article presents the first detailed study of General Gordon's remembrance in Britain between 1918 and 1972. Previous scholars have exaggerated the impact of Lytton Strachey's Eminent Victorians (1918). Strachey damaged Gordon's reputation, but part one reveals how several commentators forcefully rebutted Eminent Victorians; official commemorations, books, radio plays, and films celebrated Gordon in the 1930s, as empire featured prominently in mass culture. Didactic uses of his example by the state diminished after 1945, but parts 2 and 3 show how writers used Gordon's story to engage with new debates about Britain's role in the world, immigration and sexuality. The article reveals how a fascination with the sexuality of heroes inspired men as diverse as Viscount Robin Maugham and East End gangster Ronnie Kray to identify with Gordon. Maugham's works and the feature film Khartoum (1966) expressed nostalgia for empire during decolonization, but American screenwriter Robert Ardrey also drew on his experiences in the Congo to present a dark vision of African savagery in Khartoum, a vision performed at Pinewood studios by black immigrants from London's slums. The article questions Edward Berenson's emphasis on the 'charismatic aura' of heroes, emphasizing instead the diversity of engagements inspired through different genre.

    In this article the sets of solutions of the sine-Gordon equation and its linearization the Klein-Gordon equation are discussed and compared. It is shown that the set of solutions of the sine-Gordon equation possesses a richer structure which partly disappears during linearization. Just like the solutions of the Klein-Gordon equation satisfy the linear superposition principle, the solutions of the sine-Gordon equation satisfy a nonlinear superposition principle.

    Roberts syndrome is a genetically determined rare birth defect causing, skeletal deformities, particularly symmetrical limb reduction and craniofacial anomalies. For any child with limb and craniofacial bony malformations, this syndrome should be considered in the differentials. Although this syndrome represents only a small proportion of the total number of individuals with limb deficiency, it is important to be identified in order to give accurate genetic counselling including recurrence risk in siblings and possible prenatal diagnosis. This is the case report of a 22 days old male infant who presented with defective development of all four extremities and craniofacial abnormalities. The overall clinical and radiological features were suggestive of Roberts syndrome.

  11. Gravity localization in sine-Gordon braneworlds

    SciTech Connect

    Cruz, W.T.; Maluf, R.V.; Sousa, L.J.S.; Almeida, C.A.S.

    2016-01-15

    In this work we study two types of five-dimensional braneworld models given by sine-Gordon potentials. In both scenarios, the thick brane is generated by a real scalar field coupled to gravity. We focus our investigation on the localization of graviton field and the behaviour of the massive spectrum. In particular, we analyse the localization of massive modes by means of a relative probability method in a Quantum Mechanics context. Initially, considering a scalar field sine-Gordon potential, we find a localized state to the graviton at zero mode. However, when we consider a double sine-Gordon potential, the brane structure is changed allowing the existence of massive resonant states. The new results show how the existence of an internal structure can aid in the emergence of massive resonant modes on the brane.

    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.

    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.

    Differential quadrature method (DQM) is proposed to solve the one-dimensional quadratic and cubic Klein-Gordon equations, and two-dimensional sine-Gordon equation. We apply DQM in space direction and also blockwise in time direction. Initial and derivative boundary conditions are also approximated by DQM. DQM provides one to obtain numerical results with very good accuracy using considerably small number of grid points. Numerical solutions are obtained by using Gauss-Chebyshev-Lobatto (GCL) grid points in space intervals, and GCL grid points in each equally divided time blocks.

    2011-07-29

    Small particles have been at the heart of nanoscience since the birth of the field and now stand ready to make significant contributions to the big challenges of energy, health and sustainability. Atomic clusters show exquisite size-dependent electronic and magnetic properties and offer a new level of control in catalyses, sensors and biochips; functionalised nanocrystals offer remarkable optical properties and diverse applications in electronic devices, solar energy, and therapy. Both areas are complemented by a raft of recent advances in fabrication, characterization, and performance of a diversity of nanomaterials from the single atom level to nanowires, nanodevices, and biologically-inspired nanosystems. The goal of the 2011 Gordon Conference is thus to continue and enhance the interdisciplinary tradition of this series and discuss the most recent advances, fundamental scientific questions, and emerging applications of clusters, nanocrystals, and nanostructures. A single conference covering all aspects of nanoscience from fundamental issues to applications has the potential to create new ideas and stimulate cross fertilization. The meeting will therefore provide a balance among the three sub-components of the conference, true to its title, with a selection of new topics added to reflect rapid advances in the field. The open atmosphere of a Gordon conference, emphasizing the presentation of unpublished results and extensive discussions, is an ideal home for this rapidly developing field and will allow all participants to enjoy a valuable and stimulating experience. Historically, this Gordon conference has been oversubscribed, so we encourage all interested researchers from academia, industry, and government institutions to apply as early as possible. We also encourage all attendees to submit their latest results for presentation at the poster sessions. We anticipate that several posters will be selected for 'hot topic' oral presentations.

    2010-01-01

    We follow and modify the Feshbach-Villars formalism by separating the Klein-Gordon equation into two coupled time-dependent Schroedinger equations for the particle and antiparticle wave functions with positive probability densities. We find that the equation of motion for the probability densities is in the form of relativistic hydrodynamics where various forces have their physical and classical counterparts. An additional element is the presence of the quantum stress tensor that depends on the derivatives of the amplitude of the wave function.

    I am pleased to speak at the Fortieth Gordon Conference on Nuclear Chemistry. I served as Chairman of the first Gordon Conference on Nuclear Chemistry held June 23--27, 1952, at New Hampton, New Hampshire. In my remarks, during which I shall quote from my journal, I shall describe some of the background leading up to the first Gordon Conference on Nuclear Chemistry and my attendance at the first seven Gordon Conferences during the period 1952 through 1958. I shall also quote my description of my appearance as the featured speaker at the Silver Anniversary of the Gordon Research Conferences on December 27, 1956 held at the Commodore Hotel in New York City. I shall begin with reference to my participation in the predecessor to the Gordon Conferences, the Gibson Island Research Conferences 45 years ago, on Thursday, June 20, 1946, as a speaker. This was 15 years after the start of these conferences in 1931. Neil Gordon played a leading role in these conferences, which were named (in 1948) in his honor -- the Gordon Research Conferences -- soon after they were moved to Colby Junior College, New London, New Hampshire in 1947. W. George Parks became Director in 1947, Alexander Cruickshank became Assistant Director in 1947 and Director in 1968.

    Air Force test pilot Robert A. Rushworth is shown in an X-15. He was selected for the X-15 program in 1958, and made his first flight on November 4, 1960. Over the next six years, he made 34 flights in the X-15, the most of any pilot. This included a flight to an altitude of 285,000 feet, made on June 27, 1963. This flight above 50 miles qualified Rushworth for astronaut wings. On a later X-15 flight, he was awarded a Distinguished Flying Cross for successfully landing an X-15 after its nose wheel extended while flying at nearly Mach 5. He made his final X-15 flight on July 1, 1966, then returned to regular Air Force duties. These included a tour in Vietnam as an F-4 pilot, flying 189 combat missions. He also served as the Commander of the Air Force Flight Test Center at Edwards AFB, and as the Commander of the Air Force Test and Evaluation Center at Kirtland AFB. At the time of his retirement as a major general, he was Vice Commander, Aeronautical Systems Division, Air Force Systems Command, at Wright-Patterson AFB. Rushworth flew C-47s and C-46s as a transport pilot in World War II, as well as F-80Cs, F-101s, TF-102s, F-104s, F-105s, F-106s, and F-4s. He died on March 17, 1993.

    The fundamental properties of small particles and their potential for groundbreaking applications are among the most exciting areas of study in modern physics, chemistry, and materials science. The Clusters, Nanocrystals & Nanostructures Gordon ResearchConference and Gordon Research Seminar synthesize contributions from these inter-related fields that reflect the pivotal role of nano-particles at the interface between these disciplines. Size-dependent optical, electronic, magnetic and catalytic properties offer prospects for applications in many fields, and possible solutions for many of the grand challenges facing energy generation, consumption, delivery, and storage in the 21st century. The goal of the 2013 Clusters, Nanocrystals & Nanostructures Gordon Research Conference and Gordon Research Seminar is to continue the historical interdisciplinary tradition of this series and discuss the most recent advances, basic scientific questions, and emerging applications of clusters, nanocrystals, and nanostructures. The Clusters, Nanocrystals & Nanostructures GRC/GRS traditionally brings together the leading scientific groups that have made significant recent advances in one or more fundamental nanoscience or nanotechnology areas. Broad interests of the DOE BES and Solar Photochemistry Program addressed by this meeting include the areas of solar energy to fuels conversion, new photovoltaic systems, fundamental characterization of nanomaterials, magnetism, catalysis, and quantum physics. The vast majority of speakers and attendees will address either directly the topic of nanotechnology for photoinduced charge transfer, charge transport, and catalysis, or will have made significant contributions to related areas that will impact these fields indirectly. These topics have direct relevance to the mission of the DOE BES since it is this cutting-edge basic science that underpins our energy future.

    The 1989 conference was the tenth in the series of biennial Gordon Research Conferences on Mammary Gland Biology. Traditionally this conference brings together scientists from diverse backgrounds and experience but with a common interest in the biology of the mammary gland. Investigators from agricultural and medical schools, biochemists, cell and molecular biologists, endocrinologists, immunologists, and representatives from the emerging biotechnology industries met to discuss current concepts and results on the function and regulation of the normal and neoplastic mammary gland in a variety of species. Of the participants, approximately three-fourths were engaged in studying the normal mammary gland function, whereas the other quarter were engaged in studying the neoplastic gland. The interactions between scientists, clinicians, veterinarians examining both normal and neoplastic cell function serves to foster the multi-disciplinary goals of the conference and has stimulated many cooperative projects among participants in previous years.

  16. Gordon Fullerton in PCA (MD-11) Simulator

    NASA Technical Reports Server (NTRS)

    1998-01-01

    NASA research pilot Gordon Fullerton 'flying' in the MD-11 simulator during the Propulsion Controlled Aircraft (PCA) project. This investigation grew out of the crash of a DC-10 airliner on July 19, 1989, following an explosion in the rear engine which caused the loss of all manual flight controls. The flight crew attempted to control the airliner using only the thrust from the two remaining engines. Although the DC-10 crashed during the landing attempt, 184 of the 296 passengers and crew aboard survived. The PCA effort at the Dryden Flight Research Center grew out of the crash, and attempted to develop a means to successfully land an aircraft using only engine thrust. After more than five years of work, on August 29, 1995, Gordon Fullerton made the first PCA touchdown aboard an MD-11 airliner (a later version of the DC-10). The concept was further refined over the years that followed this first landing. Simulators were essential ingredients of the PCA development process. The feasibility of the concept was first tested with an F-15 simulator, then the results of actual flight tests in an F-15 were incorporated back into the simulator. Additional simulations were run on the Boeing 720 airliner simulator used in the Controlled Impact Demonstration project. After the MD-11 test landings, Boeing 747 and 757 simulators tested a wide range of possible situations. Simulations even helped develop a method of landing an airliner if it lost its complete hydraulic system as well as a wing engine, by transferring fuel to shift the center of gravity toward the working engine. The most extreme procedure was undertaken in a 747 simulator. The aircraft simulated the loss of the hydraulic system at 35,000 feet and rolled upside down. Then, the PCA mode was engaged, the airliner righted itself, leveled its wings, and made an approach nearly identical to that of a normal auto landing.

  2. Applied and Environmental Microbiology Gordon Research Conference

    Wall, Judy D.

    2003-11-19

    The main objective of the Gordon Research Conference on Applied and Environmental Microbiology was to present and discuss new, fundamental research findings on microorganisms, their activities in the environment, their ecosystem-level effects, and their environmental or commercial applications. To accomplish this goal, knowledge of microbial diversity, interactions and population dynamics was required. The genomic basis of microbial processes, the cycling of naturally occurring and hazardous substances, and methodologies to assess the functional relationships of microorganisms in their habitats were essential for understanding the ecological consequences of microbial activities and the formulation of generalizing principles. In the last decade, molecular technology has revealed that microbial diversity is far more extensive than the limited view obtained from culturing procedures. Great advances in environmental microbiology have resulted from the development and application of molecular approaches to ecology and molecular evolution. A further surprise resulting from the application of these new tools is the blurring of the distinction between pathogenic traits versus those considered non-pathogenic. This year's conference addressed the issues of biodiversity, its development, and the impact of stress on gene selection and expression. In addition microbial metabolic versatility with toxins such as heavy metals, antibiotics, and organic pollutants were discussed. The nine session topics were (1) biodiversity and the bacterial species, (2) mechanisms of biodiversification, (3) biofilms in health and environment, (4) a genomic view of microbial response to stress, (5) microbial use of toxic metals, (6) microbial mineral formation and dissolution, (7) power and limitations of antimicrobials, (8) biodegradation of organic pollutants, and (9) astrobiology.

  3. Gordon Research Conference on Genetic Toxicology

    SciTech Connect

    Project Director Penelope Jeggo

    2003-02-15

    Genetic toxicology represents a study of the genetic damage that a cell can incur, the agents that induce such damage, the damage response mechanisms available to cells and organisms, and the potential consequences of such damage. Genotoxic agents are abundant in the environment and are also induced endogenously. The consequences of such damage can include carcinogenesis and teratogenesis. An understanding of genetic toxicology is essential to carry out risk evaluations of the impact of genotoxic agents and to assess how individual genetic differences influence the response to genotoxic damage. In recent years, the importance of maintaining genomic stability has become increasingly recognized, in part by the realization that failure of the damage response mechanisms underlies many, if not all, cancer incidence. The importance of these mechanisms is also underscored by their remarkable conservation between species, allowing the study of simple organisms to provide significant input into our understanding of the underlying mechanisms. It has also become clear that the damage response mechanisms interface closely with other aspects of cellular metabolism including replication, transcription and cell cycle regulation. Moreover, defects in many of these mechanisms, as observed for example in ataxia telangiectasia patients, confer disorders with associated developmental abnormalities demonstrating their essential roles during growth and development. In short, while a decade ago, a study of the impact of DNA damage was seen as a compartmentalized area of cellular research, it is now appreciated to lie at the centre of an array of cellular responses of crucial importance to human health. Consequently, this has become a dynamic and rapidly advancing area of research. The Genetic Toxicology Gordon Research Conference is biannual with an evolving change in the emphasis of the meetings. From evaluating the nature of genotoxic chemicals, which lay at the centre of the early

  4. Obituary: William Gordon (1918-2010)

    Terzian, Yervant

    2011-12-01

    Bill Gordon was born in Paterson, New Jersey on January 8, 1918, and died in Ithaca, New York, on February 16, 2010. He is known as the engineer and ionospheric physicist who conceived and built the Arecibo giant radar/radio telescope. Bill graduated from Montclair State College in New Jersey and then in 1953 received his doctorate degree from Cornell University in electrical engineering, working under Henry Booker. During World War II he was in the Army where he studied the atmospheric conditions that affected radar transmissions. In the mid 1950s he began investigating giant antennas capable of studying the earths ionosphere. He succeeded in raising funds from the US Defense Department to construct the 1000 ft in diameter radar/radio telescope near the city of Arecibo on the island of Puerto Rico. The telescope was completed in 1963 under Bill's management, and he was its first Director. The huge fixed spherical antenna surface was made of a thin wire mesh allowing it to operate at frequencies up to about 600 MHz (50 cm wavelength). The spherical surface required complex 'line feeds' to correct for the spherical aberration, but allowed the telescope to track celestial radio sources by moving the line feeds which were supported by a platform suspended 500 ft above the reflector surface. Its sky coverage declination range was from -2 to +38 degrees. The large collecting area of the telescope made possible the detailed study of the physical properties of the earth's ionosphere. Measurements also included the rotation rates of the planets Mercury and Venus, radar imaging of the Moon and terrestrial planets. This new magastructure operated at low frequencies with its prime frequency at 430 MHz. One of Bill's passions was to make controlled experiments with the ionosphere. These so called 'heating experiments,' used a powerful HF radar transmitting from 5 to 10 MHz, to heat the ionosphere near the plasma frequency. The Arecibo radar then would study the heated

    The GRC series on Membranes: Materials and Processes have gained significant international recognition, attracting leading experts on membranes and other related areas from around the world. It is now known for being an interdisciplinary and synergistic meeting. The next summer's edition will keep with the past tradition and include new, exciting aspects of material science, chemistry, chemical engineering, computer simulation with participants from academia, industry and national laboratories. This edition will focus on cutting edge topics of membranes for addressing several grand challenges facing our society, in particular, energy, water, health and more generally sustainability. During the technical program, we want to discuss new membrane structure and characterization techniques, the role of advanced membranes and membrane-based processes in sustainability/environment (including carbon dioxide capture), membranes in water processes, and membranes for biological and life support applications. As usual, the informal nature of the meeting, excellent quality of the oral presentations and posters, and ample opportunity to meet many outstanding colleagues make this an excellent conference for established scientists as well as for students. A Gordon Research Seminar (GRS) on the weekend prior to the GRC meeting will provide young researchers an opportunity to present their work and network with outstanding experts. It will also be a right warm-up for the conference participants to join and enjoy the main conference.

    The Atomic and Molecular Interactions Gordon Conferences is justifiably recognized for its broad scope, touching on areas ranging from fundamental gas phase and gas-condensed matter collision dynamics, to laser-molecule interactions, photophysics, and unimolecular decay processes. The meeting has traditionally involved scientists engaged in fundamental research in gas and condensed phases and those who apply these concepts to systems of practical chemical and physical interest. A key tradition in this meeting is the strong mixing of theory and experiment throughout. The program for 2010 conference continues these traditions. At the 2010 AMI GRC, there will be talks in 5 broadly defined and partially overlapping areas of intermolecular interactions and chemical dynamics: (1) Photoionization and Photoelectron Dynamics; (2) Quantum Control and Molecules in Strong Fields; (3) Photochemical Dynamics; (4) Complex Molecules and Condensed Phases; and (5) Clusters and Reaction Dynamics. These areas encompass many of the most productive and exciting areas of chemical physics, including both reactive and nonreactive processes, intermolecular and intramolecular energy transfer, and photodissociation and unimolecular processes. Gas phase dynamics, van der Waals and cluster studies, laser-matter interactions and multiple potential energy surface phenomena will all be discussed.

    2017-04-01

    In this paper we study certain integrability properties of the supersymmetric sine-Gordon equation. We construct Lax pairs with their zero-curvature representations which are equivalent to the supersymmetric sine-Gordon equation. From the fermionic linear spectral problem, we derive coupled sets of super Riccati equations and the auto-Bäcklund transformation of the supersymmetric sine-Gordon equation. In addition, a detailed description of the associated Darboux transformation is presented and non-trivial super multisoliton solutions are constructed. These integrability properties allow us to provide new explicit geometric characterizations of the bosonic supersymmetric version of the Sym–Tafel formula for the immersion of surfaces in a Lie superalgebra. These characterizations are expressed only in terms of the independent bosonic and fermionic variables.

  4. Klein-Gordon oscillator in Kaluza-Klein theory

    In this contribution we study the Klein-Gordon oscillator on the curved background within the Kaluza-Klein theory. The problem of the interaction between particles coupled harmonically with topological defects in Kaluza-Klein theory is studied. We consider a series of topological defects, then we treat the Klein-Gordon oscillator coupled to this background, and we find the energy levels and corresponding eigenfunctions in these cases. We show that the energy levels depend on the global parameters characterizing these spacetimes. We also investigate a quantum particle described by the Klein-Gordon oscillator interacting with a cosmic dislocation in Som-Raychaudhuri spacetime in the presence of homogeneous magnetic field in a Kaluza-Klein theory. In this case, the energy spectrum is determined, and we observe that these energy levels represent themselves as the sum of the terms related with Aharonov-Bohm flux and of the parameter associated to the rotation of the spacetime.

    We study the initial value problem for the quadratic nonlinear Klein-Gordon equation vtt + v - vxx = λv2, t ∈ R, x ∈ R, with initial conditions v(0, x) = v0(x), vt(0, x) = v1(x), x ∈ R, where v0 and v1 are real-valued functions, λ ∈ R. Using the method of normal forms of Shatah ["Normal forms and quadratic nonlinear Klein-Gordon equations," Commun. Pure Appl. Math. 38, 685-696 (1985)], we obtain a sharp asymptotic behavior of small solutions without the condition of a compact support on the initial data, which was assumed in the previous work of J.-M. Delort ["Existence globale et comportement asymptotique pour l'équation de Klein-Gordon quasi-linéaire á données petites en dimension 1," Ann. Sci. Ec. Normale Super. 34(4), 1-61 (2001)].

  11. Considerations on the hyperbolic complex Klein-Gordon equation

    SciTech Connect

    Ulrych, S.

    2010-06-15

    This article summarizes and consolidates investigations on hyperbolic complex numbers with respect to the Klein-Gordon equation for fermions and bosons. The hyperbolic complex numbers are applied in the sense that complex extensions of groups and algebras are performed not with the complex unit, but with the product of complex and hyperbolic unit. The modified complexification is the key ingredient for the theory. The Klein-Gordon equation is represented in this framework in the form of the first invariant of the Poincare group, the mass operator, in order to emphasize its geometric origin. The possibility of new interactions arising from hyperbolic complex gauge transformations is discussed.

    Parashar, D.

    The scheme outlined earlier is continued here to investigate the structure of Dirac spinors in the background of a gravitational field within the context of cosmological Robertson-Walker metric where the treatment is based on general considerations of spatially curved (non-flat) hypersurfaces embracing open as well as closed versions of the Universe. A Gordon decomposition of the generalized Dirac current is then carried out in terms of the polarization and the magnetization densities. We also take a look at the Klein-Gordon equation in the curved space formalism.

    When I learned that the 2009 Earth Day features "air", I started thinking about a suitable way to link the topic to past JCE issues. No small task, considering that I had already covered oxygen and nitrogen in the 2003 and 2005 Earth Day issues. So much for chemical composition. So, I turned to physical properties—the gas laws—that could equally be called the "air laws", since "air" was a generic word for a gas in the centuries when the laws were formulated. For Earth Day 2009, I focus on Robert Boyle, who discovered the first of the gas laws. In addition to at least 20 papers describing Boyle's Law demonstrations and experiments, The Honorable Robert Boyle (1627-1691) is the subject of five papers in JCE .

    Roberts syndrome is a rare disease, with multiple limb and skeletal abnormalities (called "pseudothalidomide disease"). There are only around 150 cases described in literature. We present a case of Roberts syndrome, diagnosed in moment of delivery, after a pregnancy without prenatal follow-up. The stillborn baby was naturally delivered by a 17-year-old primiparous woman at 38 weeks of amenorrhea. The pregnancy was not followed due to socioeconomic and family situation, and no prenatal ultrasound was performed. The male baby has 2650 g and presented several morphological abnormalities and tight double umbilical abdominal loop. The macroscopic evaluation showed: dolichocephaly, hypoplastic inferior maxilla with micrognathia, antimongoloid palpebral slant, pterygium colli, abnormal and lower implanted ears, superior limbs phocomelia, syndactyly at lower left limb and tetradactyly in all limbs, bilateral cryptorchidism, pancreatic aplasia. Roberts syndrome is a rare genetic disease with recessive autosomal transmission generated by mutations in ESCO2 gene, located on chromosome 8. The disease should be easy to diagnose by antenatal ultrasound examination, but in our case, the lack of prenatal follow-up determined the diagnostic at term. We believe consider this case is an argument towards introducing ultrasound-screening compulsory to all pregnancies. To identify a possible genetic mutation, further investigations of the parents are in progress, but classically the disease has a recessive autosomal transmission.

    Gordon syndrome or distal arthrogryposis type 3 is a rare autosomal dominant disorder characterized by contractures of upper and lower limbs. It is distinguishable from other forms of distal arthrogryposis by cleft palate and short stature. Recently, Gordon syndrome has been associated to heterozygous mutations in the piezo-type mechanosensitive ion channel component 2 gene (PIEZO2). Different mutations of this gene also cause distal arthrogryposis type 5 and Marden-Walker syndrome. Dysfunction of this ion channel provides pleiotropic effects on joints, ocular muscles, and bone development. Here, we present a family with three affected individuals exhibiting multiple contractures (metacarpo-phalangeal and interphalangeal joints as well as elbow, shoulder, knee, and ankle joints), clubfeet, short stature, bifid uvula/cleft palate, and a distinct facial phenotype including ptosis. In addition, mild intellectual disability and delay in psychomotor development are obvious. The multigenerational phenotypic spectrum of Gordon syndrome is present in the 37-year-old father, his 4-year-old son and a male neonate showing typical signs of arthrogryposis in the prenatal ultrasound examination already seen at 13 week of gestation. In all affected family members, we identified the PIEZO2 mutation c.8057G>A (p.Arg2686His) by Sanger sequencing. Our analysis indicated that mild delay in psychomotor development and intellectual disability could be part of the phenotypic spectrum of Gordon syndrome. © 2016 Wiley Periodicals, Inc.

    The 2012 Gordon Research Conference on Mitochondria and Chloroplasts will assemble an international group of scientists investigating fundamental properties of these organelles, and their integration into broader physiological processes. The conference will emphasize the many commonalities between mitochondria and chloroplasts: their evolution from bacterial endosymbionts, their genomes and gene expression systems, their energy transducing membranes whose proteins derive from both nuclear and organellar genes, the challenge of maintaining organelle integrity in the presence of the reactive oxygen species that are generated during energy transduction, their incorporation into organismal signaling pathways, and more. The conference will bring together investigators working in animal, plant, fungal and protozoan systems who specialize in cell biology, genetics, biochemistry, physiology, proteomics, genomics, and structural biology. As such, this conference will provide a unique forum that engenders cross-disciplinary discussions concerning the biogenesis, dynamics, and regulation of these key cellular structures. By fostering interactions among mammalian, fungal and plant organellar biologists, this conference also provides a conduit for the transmission of mechanistic insights obtained in model organisms to applications in medicine and agriculture. The 2012 conference will highlight areas that are moving rapidly and emerging themes. These include new insights into the ultrastructure and organization of the energy transducing membranes, the coupling of organellar gene expression with the assembly of photosynthetic and respiratory complexes, the regulatory networks that couple organelle biogenesis with developmental and physiological signals, the signaling events through which organellar physiology influences nuclear gene expression, and the roles of organelles in disease and development.

    Portrait of Robert V. Hess: Hess was the head of Magnetoplasmadynamcis' (MPD)Plasma Physics Section. from Spaceflight Revolution: 'Beginning in the late 1950s, a small group of Langley researchers led by Robert V. Hess, an applied physicist from Austria who had come to work for the NACA in 1945, began pursuing two major variants of the Hall accelerator: the MPD arc and the so-called linear Hall accelerator. Throughout the 1960s, Hess and his associates refined these versions of studies of the physics and overall performance of their devices. Although they successfully demonstrated the efficiency of the MPD arc and linear Hall accelerator and made several important findings relating to the manner in which oscillations and instabilities in plasma could develop into turbulent flows, MPD researchers were never able to simulate reentry conditions or the interaction between the solar wind and the geomagnetosphere, and they would never realize meaningful applications in space propulsion. As was the case with the other MPD experimental facilities mentioned, the linear Hall-current accelerator possessed limitations that Hess and his colleagues could not eradicate. By the late 1960s, Hess and others in MPD shifted the focus of their work with these accelerators to the potential application of gas lasers.'

    School nurses may be the first health professionals to assess the onset of facial paralysis/muscle weakness in school-age children. The purpose of this study was to test the psychometric properties of the Gordon Facial Muscle Weakness Assessment Tool (GFMWT) developed by Gordon. Data were collected in two phases. In Phase 1, 4 content experts independently rated each of the 22 items on the GFMWT for content relevance. The ratings were used to generate Item and Scale Content Validity Index (CVI) scores. In Phase 2, school nurses (N = 74) attending a state conference independently rated referral urgency on a set of 10 clinical scenarios using the GFMWT. The GFMWT had an item and scale CVI of 1.0. Overall, the interrater reliability was .602 (p < .001). When used by school nurses, the GFMWT was shown to be both a reliable and a valid tool to assess facial muscle weakness in school-age children.

    2016-12-01

    In this work, we study the localization of the vector gauge field in two five-dimensional braneworlds generated by scalar fields coupled to gravity. The sine-Gordon like potentials are employed to produce different thick brane setups. A zero mode localized is obtained, and we show the existence of reverberations with the wave solutions indicating a quasi-localized massive mode. More interesting results are achieved when we propose a double sine-Gordon potential to the scalar field. The resulting thick brane shows a more detailed topology with the presence of an internal structure composed by two kinks. The massive spectrum of the gauge field is revalued on this scenario revealing the existence of various resonant modes. Furthermore, we compute the corrections to Coulomb law coming from these massive KK vector modes in these thick scenarios, which is concluded that the dilaton parameter regulates these corrections.

    2009-08-01

    A comprehensive symmetry analysis of the {\\cal N}=1 supersymmetric sine-Gordon equation is performed. Two different forms of the supersymmetric system are considered. We begin by studying a system of partial differential equations corresponding to the coefficients of the various powers of the anticommuting independent variables. Next, we consider the super-sine-Gordon equation expressed in terms of a bosonic superfield involving anticommuting independent variables. In each case, a Lie (super)algebra of symmetries is determined and a classification of all subgroups having generic orbits of codimension 1 in the space of independent variables is performed. The method of symmetry reduction is systematically applied in order to derive invariant solutions of the supersymmetric model. Several types of algebraic, hyperbolic and doubly periodic solutions are obtained in explicit form.

    "I slept and dreamed that life was beauty. I woke - and found that life was duty." This quote from the poet Ellen Sturgis Hooper, could be attributed to Robert Wingfield, who has persevered in his quest for personal and professional excellence. This historical biography begins with his genealogy, going back to the 11(th) century in Merry England and ends in 2015, with his relatively quiet existence still centred in Ontario. The essay scrutinizes Dr. Wingfield's accomplishments for the Ontario Chiropractic Association (OCA), Canadian Chiropractic Association (CCA) and Ontario Board of Directors of Chiropractic (BDC). Moreover, it attempts to give the reader a glimpse into his personal endeavours, to help us fathom how he tackles (as William Shakespeare would say) "the thousand natural shocks that flesh is heir to."

  4. Color and Contingency in Robert Boyle's Works.

    PubMed

    Baker, Tawrin

    2015-01-01

    This essay investigates the relationship between color and contingency in Robert Boyle's Experiments and Considerations Touching Colours (1664) and his essays on the unsuccessfulness of experiments in Certain Physiological Essays (1661). In these two works Boyle wrestles with a difficult practical and philosophical problem with experiments, which he calls the problem of contingency. In Touching Colours, the problem of contingency is magnified by the much-debated issue of whether color had any deep epistemic importance. His limited theoretical principle guiding him in Touching Colours, that color is but modified light, further exacerbated the problem. Rather than theory, Boyle often relied on craftsmen, whose mastery of color phenomena was, Boyle mentions, brought about by economic forces, to determine when colors were indicators of important 'inward' properties of substances, and thus to secure a solid foundation for his experimental history of color.

    Taylor, Patrick T.; Purucker, Michael E.

    Robert (Bob) Langel died on February 9, 2000, in Blacksburg,Virginia, after a three-month illness. Bob was a member of the AGU since 1968 and a Fellow since 1989. He pioneered measurement, separation, charting, and interpretation of the multitude of magnetic fields observed in near-Earth space. His special gift was in bringing together workers in fields as diverse as rock magnetism, tectonics, core-flow modeling, ionospheric physics, and applied mathematics, and in learning from them all. He was born in Pittsburgh, Pennsylvania (1937), and raised in Ohio. He earned a B.S. in physics at Wheaton College, Illinois (1959), and subsequently spent his entire professional career as a federal scientist, first at the Naval Research Laboratory (1959-1962) and then with NASAs Goddard Space Flight Center until his retirement in 1997.

    The Wood's lamp aids in the diagnosis of multiple infectious, inflammatory and neoplastic dermatologic conditions. Although the Wood's lamp has many applications, which have improved both the diagnosis and management of disease, the man credited for its invention is relatively unknown in medicine. Robert Williams Wood, a prominent physicist of the early 20th century, is credited for the invention of the Wood's lamp. Wood was the father of infrared and ultraviolet photography and made significant contributions to other areas in optics and spectroscopy. Wood's work encompassed the formative years of American Physics; he published over 200 original papers over his lifetime. A few years after the invention of the Wood's lamp for ultraviolet photography, physicians in Europe adopted the Wood's lamp for dermatologic applications. Wood's lamp remains popular in clinics globally, given its ease of use and ability to improve diagnostic precision.

    Johnson, Martin H

    2011-01-01

    The early influences on Robert Edwards’ approach to the scientific research that led to human IVF are described. His interest as a graduate student in the genetics of early mammalian development stimulated him later to investigate whether the origins of human genetic diseases such as Down, Klinefelter and Turner syndromes might be explained by events during egg maturation. This clinical problem provided the most powerful stimulus to achieve both oocyte maturation and fertilization in vitro in humans. Indeed, preimplantation genetic diagnosis was his main goal until he met Patrick Steptoe in 1968. A re-evaluation of his meeting with Steptoe suggests that initially Steptoe’s laparoscopic skill was of interest for its potential to solve the sperm capacitation problem. Steptoe’s impact on Edwards was twofold. First, Steptoe’s long-held interest in infertility raised this application of IVF higher in Edwards’ priorities. Second, Steptoe offered a long-term partnership, in which oocyte collection without in-vitro maturation was a possibility. The professional criticism generated by their work together encouraged Edwards to pursue a deliberate programme of public education about the issues raised and to challenge and develop professional bioethical thought and discourse about reproduction. The early life and career of Robert Edwards are described and re-evaluated in the light of documentary evidence. His early interest in the genetics of development provided the major motivation behind his goal of achieving IVF in humans. Through this work, he aimed to understand and hopefully to reduce the transmission of genetic disease in humans. His meeting with Patrick Steptoe, the details of which are re-examined, increased the significance for Edwards of infertility as an outcome of IVF. It also led to a creative long-term research partnership, initiated a long-term programme of public education in the UK about reproductive science and stimulated the development of

    The Liouville correspondence between the short-pulse integrable hierarchy and the sine-Gordon integrable hierarchy is studied. It is shown that the transformation relating the short-pulse equation with the sine-Gordon equation also establishes the correspondence between their flows and Hamiltonian conservation laws in respective hierarchy. This proposes an alternative approach to derive the Hamiltonian conservation laws of the short-pulse equation from the known ones of the classical sine-Gordon equation.

    2008-03-01

    J. Robert Oppenheimer was among the most important and enigmatic figures in 20th century science. He is best known for successfully directing the Manhattan Project that produced the first atomic bombs that were dropped on Japan at the end of World War II. Subsequently, he became a scientist and statesman who advised the United States government in the areas of atomic weapons development and public policy. He later became subject to an investigation in 1954 into his previous political affiliations and his personal behavior that ended in the revoking of his security clearance. This essay seeks to chronicle Oppenheimer's coming of age as a public intellectual with a view toward his own psychological history and most especially in relationship to the stages of faith development articulated by James Fowler and colleagues. Moreover, though not conventionally religious, Oppenheimer's life and thought were permeated with themes and ideas of a religious and ethical nature that shaped his adult character and informed his view of the world. This essay was originally presented at The Richardson History of Psychiatry Research Seminar at Weill Cornell Medical College.

  18. Robert Carswell: the first illustrator of MS.

    Murray, T J

    2009-09-01

    The first illustration of multiple sclerosis (MS) was by a young Scottish physician and artist, Dr Robert Carswell. Recognized as a talented illustrator by his teachers, he was encouraged to create an anatomy and pathology atlas. He spent years in the hospitals and mortuaries of Paris and Lyon painting watercolours and pen and ink drawings of patients and post mortem preparations. Of the 1034 paintings, 99 are of the brain and spinal cord and Plate 4, figure 4.4 in the atlas (Figure 2), is of MS. Carswell indicated he saw two examples of this pathology, but had not examined either patient, but illustrated one of them. We know little about the clinical history other than that the patient was paralyzed. About 200 of the atlases were printed, and it is still regarded as one of the greatest and most beautiful of all medical books. Carswell was appointed as the first Professor of Anatomy at the North London Hospital, later renamed the University College Hospital UK, where the original copy of his great atlas is archived. Due to ill health he resigned after a few years to reside in the healthier air outside Brussels, Belgium. He was appointed physician to King Leopold, but was also noted for his care of the poor. Queen Victoria knighted him for his care of King Louis Philippe of France when he was in exile. Although English journals did not note his passing at the age of 64 years, his great atlas remains as his memorial.

He was nationally and internationally recognized as an outstanding scientist in hydrogeology and groundwater hydrology. He was a pioneer authority in the development and application of analog- and digital-computer simulations that aid in the analysis and prediction of the responses of highly complex aquifer systems to stresses imposed by man's development and utilization. He conducted basic research in petrophysics to define the fundamental principles governing permeability distribution and its directional characteristics and to elucidate the manner in which the permeability factor controls the movement of water in aquifer systems. He tested the applicability of the concepts he developed with prototype studies of the Ten-sleep sandstone in the Big Horn Basin of Wyoming and of the Carrizo sandstone in the Coastal Plain of Texas.

  20. Robert Knox and the anatomy of beauty.

    Neher, Allister

    2011-06-01

    Robert Knox (1791-1862) is typically remembered as the Edinburgh anatomist to whom the murderers Burke and Hare sold the bodies of their victims. This association brought Knox infamy and damaged his life and career. Before the Burke and Hare scandal, Knox was one of the most famous, original and influential anatomists in Britain. He was also something of a dandy with a sophisticated appreciation of the visual arts. His most significant writings on artistic subjects were his books A Manual of Artistic Anatomy and Great Artists and Great Anatomists: A Biographical and Philosophical Study. Knox's interesting and independently minded opinions on the central artistic questions of his day were taken seriously by his contemporaries. His demotion in the official history of anatomy following his involvement with Burke and Hare, however, also removed him from the history of art theory in 19th century Britain. Knox was such a magnetic and impressive figure, though, that he has to be brought back to his era and his era is not complete without him. This paper discusses how Knox's writings on anatomy and biology shaped his contributions to art theory. It is a first step towards returning Knox, the art theorist, to the cultural life of 19th century Britain.

    SciTech Connect

    Nandori, I.; Nagy, S.; Sailer, K.; Trombettoni, A.

    2009-07-15

    The scheme dependence of the renormalization group (RG) flow has been investigated in the local potential approximation for two-dimensional periodic, sine-Gordon type field-theoretic models discussing the applicability of various functional RG methods in detail. It was shown that scheme-independent determination of such physical parameters is possible as the critical frequency (temperature) at which Kosterlitz-Thouless-Berezinskii type phase transition takes place in the sine-Gordon and the layered sine-Gordon models, and the critical ratio characterizing the Ising-type phase transition of the massive sine-Gordon model. For the latter case, the Maxwell construction represents a strong constraint on the RG flow, which results in a scheme-independent infrared value for the critical ratio. For the massive sine-Gordon model also the shrinking of the domain of the phase with spontaneously broken periodicity is shown to take place due to the quantum fluctuations.

    By introducing the scalar potential as modification in the mass term of the Klein–Gordon equation, the influence of a Coulomb-type potential on the Klein–Gordon oscillator is investigated. Relativistic bound states solutions are achieved to both attractive and repulsive Coulomb-type potentials and the arising of a quantum effect characterized by the dependence of angular frequency of the Klein–Gordon oscillator on the quantum numbers of the system is shown. - Highlights: • Interaction between the Klein–Gordon oscillator and a modified mass term. • Relativistic bound states for both attractive and repulsive Coulomb-type potentials. • Dependence of the Klein–Gordon oscillator frequency on the quantum numbers. • Relativistic analogue of a position-dependent mass system.

    2011-12-01

    Robert H. Koch, emeritus professor of astronomy and astrophysics at the University of Pennsylvania, passed away at his home in Ardmore, Pennsylvania on 11 October 2010 after a brief illness. Bob was 80 years old and remained sharp and intellectually engaged with the astronomical community up until the onset of complications from a brain tumor. Bob was born in York, Pennsylvania on 19 December 1929, and graduated from York Catholic High School in 1947. He attended the University of Pennsylvania on a senatorial scholarship, graduating in 1951. After two years in the United States Army, he enrolled in graduate school at the University of Pennsylvania, doing his doctoral research on the photoelectric photometry of R CMa, AO Cas, AS Eri, and XY Leo at the Steward Observatory, University of Arizona in Tucson. Bob would continue this exploration of close binary stars, their atmospheres and interactions, for the rest of his career. Bob met his future spouse, Joanne C. Underwood, while in graduate school in 1957 and they were married in 1959. Bob received his PhD in astronomy in 1959 and moved to Amherst, Massachusetts, where he taught as a member of the Four College Astronomy Department until 1966. Following a year at the University of New Mexico in Albuquerque, Bob joined the Astronomy Department at Penn, teaching and doing research there until his retirement in 1996. Bob's main interests were the study of close and eclipsing binary stars, stellar envelopes and winds, intrinsic variables, transits and occultations, and the Milky Way Galaxy, producing well over 100 refereed publications. Bob was partial to photoelectric photometry and polarimetry, conducting most of his observational research at the University of Pennsylvania Flower and Cook Observatory, and at other ground- and space-based observatories. As an international figure in the area of binary stars, Bob had widespread collaborations with scientists at other institutions, in the US and throughout the world, and

    2011-09-01

    Twisted U- and twisted U/K-hierarchies are soliton hierarchies introduced by Terng to find higher flows of the generalized sine-Gordon equation. Twisted O(J,J)/O(J)× O(J)-hierarchies are among the most important classes of twisted hierarchies. In this paper, we derive explicit interesting first and higher flows of twisted O(J,J)/O(J)× O(J)-hierarchies, justify that the one-dimensional systems of twisted O(J,J)/O(J)× O(J)-hierarchies for J = Iq, n - q(1 ⩽ q ⩽ n - 1), called the generalized sinh-Gordon equations, are the Gauss-Codazzi equations for n-dimensional timelike submanifolds with constant sectional curvature 1 and index q in pseudo-Euclidean (2n - 1)-dimensional space {R}^{2n-1}_{2q-1} with index 2q - 1. Furthermore, a unified treatment of the inverse scattering theory for twisted O(J,J)/O(J)× O(J)-hierarchies is provided.

    The Gordon Research Conference (GRC) on GRAVITATIONAL EFFECTS ON LIVING SYSTEMS was held at COLBY SAYWER 2 from 7/12/98 thru 7/17/98. The Conference was well-attended with 94 participants (attendees list attached). The attendees represented the spectrum of endeavor in this field coming from academia, industry, and government laboratories, both U.S. and foreign scientists, senior researchers, young investigators, and students. In designing the formal speakers program, emphasis was placed on current unpublished research and discussion of the future target areas in this field. There was a conscious effort to stimulate lively discussion about the key issues in the field today. Time for formal presentations was limited in the interest of group discussions. In order that more scientists could communicate their most recent results, poster presentation time was scheduled. Attached is a copy of the formal schedule and speaker program and the poster program. In addition to these formal interactions, "free time" was scheduled to allow informal discussions. Such discussions are fostering new collaborations and joint efforts in the field. As you know, in the interest of promoting the presentation of unpublished and frontier-breaking research, Gordon Research Conferences does not permit publication of meeting proceedings.

  5. Numerical computation of travelling breathers in Klein Gordon chains

    NASA Astrophysics Data System (ADS)

    Sire, Yannick; James, Guillaume

    2005-05-01

    We numerically study the existence of travelling breathers in Klein-Gordon chains, which consist of one-dimensional networks of nonlinear oscillators in an anharmonic on-site potential, linearly coupled to their nearest neighbors. Travelling breathers are spatially localized solutions having the property of being exactly translated by p sites along the chain after a fixed propagation time T (these solutions generalize the concept of solitary waves for which p=1). In the case of even on-site potentials, the existence of small amplitude travelling breathers superposed on a small oscillatory tail has been proved recently [G. James, Y. Sire, Travelling breathers with exponentially small tails in a chain of nonlinear oscillators, Commun. Math. Phys., 2005, in press (available online at http://www.springerlink.com)], the tail being exponentially small with respect to the central oscillation size. In this paper, we compute these solutions numerically and continue them into the large amplitude regime for different types of even potentials. We find that Klein-Gordon chains can support highly localized travelling breather solutions superposed on an oscillatory tail. We provide examples where the tail can be made very small and is difficult to detect at the scale of central oscillations. In addition, we numerically observe the existence of these solutions in the case of non-even potentials.

  6. Breather-like structures in modified sine-Gordon models

    NASA Astrophysics Data System (ADS)

    Ferreira, L. A.; Zakrzewski, Wojtek J.

    2016-05-01

    We report analytical and numerical results on breather-like field configurations in a theory which is a deformation of the integrable sine-Gordon model in (1  +  1) dimensions. The main motivation of our study is to test the ideas behind the recently proposed concept of quasi-integrability, which emerged from the observation that some field theories possess an infinite number of quantities which are asymptotically conserved in the scattering of solitons, and periodic in time in the case of breather-like configurations. Even though the mechanism responsible for such phenomena is not well understood yet, it is clear that special properties of the solutions under a space-time parity transformation play a crucial role. The numerical results of the present paper give support for the ideas on quasi-integrability, as it is found that extremely long-lived breather configurations satisfy these parity properties. We also report on a mechanism, particular to the theory studied here, that favours the existence of long lived breathers even in cases of significant deformations of the sine-Gordon potential. We also find numerically that our breather-like configurations decay through the gradual increase of their frequency of oscillations.

  7. Dissipative effects in nonlinear Klein-Gordon dynamics

    NASA Astrophysics Data System (ADS)

    Plastino, A. R.; Tsallis, C.

    2016-03-01

    We consider dissipation in a recently proposed nonlinear Klein-Gordon dynamics that admits exact time-dependent solutions of the power-law form e_qi(kx-wt) , involving the q-exponential function naturally arising within the nonextensive thermostatistics (e_qz \\equiv [1+(1-q)z]1/(1-q) , with e_1^z=ez ). These basic solutions behave like free particles, complying, for all values of q, with the de Broglie-Einstein relations p=\\hbar k , E=\\hbar ω and satisfying a dispersion law corresponding to the relativistic energy-momentum relation E2 = c^2p2 + m^2c4 . The dissipative effects explored here are described by an evolution equation that can be regarded as a nonlinear generalization of the celebrated telegraph equation, unifying within one single theoretical framework the nonlinear Klein-Gordon equation, a nonlinear Schrödinger equation, and the power-law diffusion (porous-media) equation. The associated dynamics exhibits physically appealing traveling solutions of the q-plane wave form with a complex frequency ω and a q-Gaussian square modulus profile.

    Schoenherr, Neil T.

    2004-12-01

    Robert M. Walker, PhD, Professor of Physics in Arts & Sciences and a faculty fellow of the McDonnell Center for the Space Sciences, died of stomach cancer Thursday, 12 February 2004, in Brussels, Belgium. He was 75. Walker worked on the frontiers of space research for more than four decades. Robert Walker was born in Philadelphia on 6 February 1929. His mother was Dorothy Potter and he considered Roger Potter his father though he was not his biological father. His early years were spent in New York City and in upstate New York. He attended the Bronx High School of Science, earned his BS in physics from Union College and in 1954, he received his PhD in particle physics from Yale University. He subsequently joined the General Electric Laboratory in Schenectady, New York where he studied the radiation effects in solids. His work on defects in irradiated copper is still regarded as the definitive work on the topic. In the early 1960s, Walker's discovery of fossil nuclear particle tracks in minerals was instrumental to new developments in geo-chronology and cosmic ray physics. In particular, his discovery of tracks from nuclei heavier than iron opened a new frontier of cosmic ray physics. He subsequently pioneered the use of plastics to detect and count such nuclei in cosmic ray balloon flights. Beginning in 1966, when he moved to Washington University and became the first McDonnell Professor of Physics, his research interests turned more toward space physics. He was the inaugural director of the McDonnell Center, which was established in 1975 by a gift from aerospace pioneer James S. McDonnell. Walker was a member of the NASA committee that allocated samples of the first returned lunar materials, and his laboratory led the way in deciphering their record of lunar, solar system and galactic evolution. Together with Ghislaine Crozaz and other colleagues, Walker made path breaking laboratory studies of the first moon rocks revealing the history of solar radiation and

The flight experiments included studies of the aircraft's exterior surface, internal structure, engine temperatures, boundary-layer airflow, the wing's ground-effect characteristics, interior and exterior noise, handling qualities in various flight profiles, and in-flight structural flexibility. The ground tests studied the effect of air inlet structures on airflow entering the engine and the effect on engine performance when supersonic shock waves rapidly change position in the engine air inlet. A second phase of testing further studied the original six in-flight experiments with additional instrumentation installed to assist in data acquisition and analysis. A new experiment aimed at measuring the in-flight deflections of the wing and fuselage was also conducted. American-supplied transducers and sensors were installed to measure nose boom pressures, angle of attack, and sideslip angles with increased accuracy. Two NASA pilots, Robert Rivers of Langley Research Center, Hampton, Virginia, and Gordon Fullerton from Dryden Flight Research Center, Edwards, California, assessed the aircraft's handling at subsonic and supersonic speeds during three flight tests in September 1998. The program concluded after four more data-collection flights in the spring of 1999. The Tu-144LL model had new Kuznetsov NK-321 turbofan engines rated at more than 55,000 pounds of thrust in full afterburner. The aircraft is 215 feet, 6 inches long and 42 feet, 2 inches high with a wingspan of 94 feet, 6 inches. The aircraft is constructed mostly of light aluminum alloy with titanium and stainless steel on the leading edges, elevons, rudder, and the under-surface of the rear fuselage.

  12. The Gordon Gordon-Taylor Memorial Lecture: surgical giants and giants among surgeons--the case of Abraham Colles.

    PubMed

    Little, Miles

    2006-12-01

    Sir Gordon Gordon-Taylor was a surgical giant and a giant among surgeons. There's a distinction between the two. Surgical giants are technical geniuses who pave the way for others and set the standards against which others can measure their performance. Giants among surgeons contribute other things to the science and practice of surgery and sometimes to fields outside surgery. By these measures, Abraham Colles was not a surgical giant. He thought, wrote and taught about his interests. He enhanced the reputation of Irish surgery. In retrospect, his science and his ethics seem flawed by modern standards, but by the measures of his own time he was a model investigator and a man of outstanding moral probity. He is remembered for the eponymous Colles's fracture and for Colles's fascia and ligament. He held the Chair of Anatomy and Surgery in Dublin for 32 years and drew the admiration and affection of his contemporaries, colleagues and students. He was a giant among surgeons, and his name deserves commemoration.

  16. Zero temperature landscape of the random sine-Gordon model

    SciTech Connect

    Sanchez, A.; Bishop, A.R.; Cai, D.

    1997-04-01

    We present a preliminary summary of the zero temperature properties of the two-dimensional random sine-Gordon model of surface growth on disordered substrates. We found that the properties of this model can be accurately computed by using lattices of moderate size as the behavior of the model turns out to be independent of the size above certain length ({approx} 128 x 128 lattices). Subsequently, we show that the behavior of the height difference correlation function is of (log r){sup 2} type up to a certain correlation length ({xi} {approx} 20), which rules out predictions of log r behavior for all temperatures obtained by replica-variational techniques. Our results open the way to a better understanding of the complex landscape presented by this system, which has been the subject of very many (contradictory) analysis.

  17. Gordon S. Fulcher: Renaissance Man of Glass Science

    NASA Astrophysics Data System (ADS)

    Mauro, John

    2014-11-01

    To a glass scientist, the name “Fulcher” conjures images of viscosity vs. temperature diagrams for glass-forming liquids. Indeed, Gordon Fulcher’s seminal 1925 publication, in which he proposed his three-parameter model of viscosity, is one of the most significant and influential papers ever published in the field of glass science. Fulcher developed this equation during the early part of his 14-year career at Corning Glass Works (1920-1934). However, Fulcher’s work in viscosity represents a small fraction of his highly diverse and accomplished career, which included pioneering the field of electrocast ceramics and developing the modern system of scientific abstracting that it still in use today. Fulcher also had a keen interest in social and economic problems, and his latter research focused heavily on the field of metacognition, i.e., the process of thinking.

  19. Obituary: Robert C. Bless (1927 - 2015)

    NASA Astrophysics Data System (ADS)

    Surrounded by his loving family, Robert Charles Bless died at home on November 29th, three days before his 88th birthday. He was born in Ithaca, NY on Dec. 3, 1927 to a Russian father, Arthur Aaron Bless, and a French mother, Eva Chantrell Bless. Bob spent many summers on the family farm in the South of France, where he gained a great pride and joy in his French heritage, large extended family, and mother tongue. As a child growing up in Gainesville, FL, Bob's first job was snake wrangling, earning 10 cents per foot, with an added bonus for the more venomous species. Young Robbie took daily adventures in the Florida woods and swamps, armed only with pockets full of pecans and oranges. He enjoyed spending time at the family's lake cabin, where he learned to sail and helped his father plant acres of trees to grow their timber plantation. As a first generation immigrant, Bob's father received a PhD in physics, which inspired Bob to pursue an extensive educational route in astrophysics. Bob excelled in academics, graduating high school at the age of 16 and the University of Florida (B.Sc.) at 19. His path to graduate school was interrupted by a diagnosis of tuberculosis that forced him into a Florida sanitorium for one year. During this time, Bob made the most of what he described as the most dismal part of life by advocating for patient rights, initiating an inter-sanitorium newsletter, and gaining skills and experience in community organization and leadership - qualities that would later inform his leadership in academe. After being one of the first successfully treated tuberculosis patients in the US, Bob went on to earn a M.Sc. from Cornell University, and received his PhD degree in Astronomy from the University of Michigan in 1958. That same year, Bob joined the staff of the Astronomy Department of the University of Wisconsin (UW), Madison. It was there that Bob met Diane McQueen. Despite Bob's Dodge Dart and what has been described as the worst first date in

  20. A higher-order Robert-Asselin type time filter

    NASA Astrophysics Data System (ADS)

    Li, Yong; Trenchea, Catalin

    2014-02-01

    The Robert-Asselin (RA) time filter combined with leapfrog scheme is widely used in numerical models of weather and climate. It successfully suppresses the spurious computational mode associated with the leapfrog method, but it also weakly dampens the physical mode and degrades the numerical accuracy. The Robert-Asselin-Williams (RAW) time filter is a modification of the RA filter that reduces the undesired numerical damping of RA filter and increases the accuracy. We propose a higher-order Robert-Asselin (hoRA) type time filter which effectively suppresses the computational modes and achieves third-order accuracy with the same storage requirement as RAW filter. Like RA and RAW filters, the hoRA filter is non-intrusive, and so it would be easily implementable. The leapfrog scheme with hoRA filter is almost as accurate, stable and efficient as the intrusive third-order Adams-Bashforth (AB3) method.

    Secondary hypertension co-occurrence with hyperkalaemia is not an expected finding. Gordon's syndrome is an autosomal dominant disease which is a rare cause of secondary hypertension and hyperkalaemia is the most important feature. Normal glomerular filtration rate, hyperchloraemic metabolic acidosis, low renin, generally normal aldosterone levels and sensitivity to thiazide diuretics are the other features. A 33-year old male patient presented with hypertension and hyperkalaemia. Due to familial hypertension history, normal serum urea, creatinine levels and lack of drug use, we assumed that our patient had Gordon's syndrome. Gordon's syndrome is a rare cause of hypertension, and mostly reported only as case reports. Gordon's syndrome should be considered in the differential diagnosis of hyperkalaemic hypertensive patients with normal renal function.

    Snodgrass, Herschel B.

    2009-01-01

    It is with great sadness that I report the passing of Peter Robert Wilson, a well-known and well-loved figure in the solar physics community. Peter was on the faculty of the Department of Applied Mathematics at the University of Sydney for 39 years, and Chair of the department for 24 of these years. He was the author or co-author of more than 80 scientific research papers and a book, Solar and Stellar Activity Cycles (1994), published by Cambridge University Press. He died suddenly of a heart attack, at his home in Glebe, Australia, in the early morning of 11 November 2007. Peter was an organizer of, and participant in, many international conferences and workshops. He traveled extensively, holding visiting appointments at the University of Colorado (JILA), at Cambridge University, at the College de France (Paris), and at the California Institute of Technology [CalTech]. Most of his work was in the field of solar physics, but he also did some work on the philosophy of science and on tides. Peter came from a line of mathematicians. His father, Robert Wilson, immigrated to Australia from Glasgow in 1911, and became a mathematics teacher at Scotch College, a private school in Melbourne. There his name was changed to 'Bill' because 'Bob' was already taken." Peter's enjoyment of this story as characteristic of Australian academia (as any fan of Monty Python would understand) is indicative of his infectious sense of humor. In a similar vein, he claimed ancestry traced back to the eighteenth-century Scottish mathematician Alexander Wilson, Professor of Astronomy at the University of Glasgow. That Wilson is famous in the solar physics community for his discovery, known as the "Wilson Effect," of the photospheric depressions associated with sunspots. Peter himself could not resist writing a paper on this subject, and was delighted when the bait was taken by some less-informed colleagues who chided him for "naming an effect after himself."

    We report an infant with double trisomy 48,XXX,+18, who also displayed features of Roberts syndrome. All previously published cases with similar double trisomy have presented with features of trisomy 18 syndrome. The chromosome analysis done at birth revealed the double trisomy; parental chromosomes were normal. The proband presented with microbrachycephaly, unilateral cleft lip and palate, choanal atresia, midfacial capillary hemanioma, thin nares, shallow orbits, malformed ears, sparse hair, hypomelia of the upper limbs, rocker-bottom feet, auricular septal defect and agenesis of the corpus callosum. Characteristic features of Roberts syndrome included hypomelia, midfacial defects, and severe growth deficiency. Among the many different features reported in the literature for patients with trisomy 18 syndrome, the most consistent were growth deficiency, clenched fingers and congenital heart defects (e.g. VSD, ASD, PDA). Although some of our patient`s features such as cleft lip and cleft palate, low-set malformed ears, ASD, defects of the corpus callosum, choanal atresia, radial aplasia could also be seen in trisomy 18 syndrome (in 10-50% of the cases), her phenotype was more typical of Roberts syndrome because of symmetrical hypomelia and midfacial defects. Our patient`s chromosomes did not show premature separation of centromeric heterochromatin, a feature reported to occur in approximately one-half of individuals with Roberts syndrome. Sporadic aneuploidy involving different chromosomes has been found in lymphocyte cultures from some Roberts syndrome patients and is considered by some authors as a mitotic mutant. This aneuploidy is most likely to be chromosome gain. The simultaneous occurrence of trisomy X and 18 is extremely rare with only 11 cases having been reported in the literature. Our patient is unique since she has the double trisomy in addition to the characteristic features of Roberts syndrome.

  7. Approximate symmetry and solutions of the nonlinear Klein-Gordon equation with a small parameter

    NASA Astrophysics Data System (ADS)

    Rahimian, Mohammad; Toomanian, Megerdich; Nadjafikhah, Mehdi

    In this paper, the Lie approximate symmetry analysis is applied to investigate new solutions of the nonlinear Klein-Gordon equation with a small parameter. The nonlinear Klein-Gordon equation is used to model many nonlinear phenomena. The hyperbolic function method and Riccati equation method are employed to solve some of the obtained reduced ordinary differential equations. We construct new analytical solutions with a small parameter which is effectively obtained by the proposed method.

  8. Dr Robert Proust: a gynaecologist's contribution to world literature.

    2013-09-01

    Dr Robert Proust, though overshadowed in history by his more famous brother, the novelist Marcel Proust, was an eminent and innovative French surgeon who achieved recognition largely as a gynaecologist, but also was an accomplished urologist and general surgeon. He was the author of a textbook, The surgery of the female genital tract, that was very successful in his lifetime and ran to six editions. He was always very supportive of his brother's writing, and after Marcel's premature death Robert edited and arranged for publication of the final three volumes of his novel À la recherche du temps perdu, which has been called the greatest novel of the twentieth century.

  9. Obituary: Robert Fleischer, 1918-2001

    NASA Astrophysics Data System (ADS)

    Boyce, Peter Bradford; Saffell, Mary E.

    2003-12-01

    Robert Fleischer was born 20 August 1918 to Leon and Rose Fleischer in Flushing, NY. He was educated at Harvard, receiving his BS in 1940, MA in 1947, and PhD in 1949. He specialized in geophysics and solar-terrestrial relations. Fleischer joined the faculty at Rensselaer Polytechnic Institute advancing from Assistant to Full professor in 1958. As Director of the RPI Observatory, Fleischer attempted to bring modern astronomy to the institutions in the Albany area by procuring the funds to build a radio telescope. He left for the National Science Foundation (NSF) before the observatory was completed. It is a testament to his character that without his enormous energy, organizational, and fundraising abilities, the radio telescope project languished after he left. Fleischer joined the NSF in 1962 as the Program Director for Solar-Terrestrial Research. He was the government-wide Coordinator for the International Quiet Sun Years, and coordinated the 1966 South American Eclipse expeditions. Thereafter, he was appointed Deputy Head of the Office of International Science Activities. Fleischer is most notably remembered as the head of the Astronomy Section at the National Science Foundation. He brought astronomy into its own at NSF and involved the community in a major way through use of advisory committees. He was dedicated to helping the astronomical community understand the funding system, the political environment, and the various factors in how money is allocated. Fleischer truly believed in the concept that scientists should be making the important decisions about their field. He was instrumental in injecting science into the oversight of the National Observatories. Relations with the community say a lot about the man, the complexities of his character, and the forces that drove him. Fleischer was passionate in his beliefs and in his devotion to doing the best for astronomy. His strong approach and belief in himself served him well in many ways, but caused him grief

    The Gordon Research Conference (GRC) on GRAVITATIONAL EFFECTS ON LIVING SYSTEMS was held at COLBY SAYWER 2 from 7/12/98 thru 7/17/98. The Conference was well-attended with 94 participants. The attendees represented the spectrum of endeavor in this field coming from academia, industry, and government laboratories, both U.S. and foreign scientists, senior researchers, young investigators, and students. In designing the formal speakers program, emphasis was placed on current unpublished research and discussion of the future target areas in this field. There was a conscious effort to stimulate lively discussion about the key issues in the field today. Time for formal presentations was limited in the interest of group discussions. In order that more scientists could communicate their most recent results, poster presentation time was scheduled. A copy of the formal schedule and speaker program and the poster program is included. In addition to these formal interactions, "free time" was scheduled to allow informal discussions. Such discussions are fostering new collaborations and joint efforts in the field.

  11. The 1990 Gordon Research Conference on Crystal Growth

    NASA Astrophysics Data System (ADS)

    Brown, Margaret

    1990-04-01

    The program was designed to present a range of topics and views within the broad theme of the conference. Sessions included papers on bulk and thin film crystal growth experiments and modeling, high T sub c superconductors (uses and crystal growth), II-VI compounds, and crystal characterization. Twenty full length papers were presented in eight sessions, chaired by acknowledged experts in the session field. Each session chair gave an introduction to his session and fostered discussions following the presentations. Two papers included impressive videotape displays of the theory and practice of crystal growth that greatly enhanced the understanding of the subjects verbally presented. The format of the Gordon conference allows ample unstructured time for informal discussion of program and other related topics, and participants remarked on how much they enjoyed these active discussion periods to pursue points brought up in the formal sessions. Students and newcomers to the crystal growth community gained much from interacting informally with experienced scientists and learning from them. One session devoted to short verbal presentations of posters, to introduce authors and topics to the audience, proved to be a very successful experiment. Poster viewing sessions followed later, when authors were able to discuss their work in more detail.

  13. 2010 Thin Film & Small Scale Mechanical Behavior Gordon Research Conference

    SciTech Connect

    Dr. Thomas Balk

    2010-07-30

    Over the past decades, it has been well established that the mechanical behavior of materials changes when they are confined geometrically at least in one dimension to small scale. It is the aim of the 2010 Gordon Conference on 'Thin Film and Small Scale Mechanical Behavior' to discuss cutting-edge research on elastic, plastic and time-dependent deformation as well as degradation mechanisms like fracture, fatigue and wear at small scales. As in the past, the conference will benefit from contributions from fundamental studies of physical mechanisms linked to material science and engineering reaching towards application in modern applications ranging from optical and microelectronic devices and nano- or micro-electrical mechanical systems to devices for energy production and storage. The conference will feature entirely new testing methodologies and in situ measurements as well as recent progress in atomistic and micromechanical modeling. Particularly, emerging topics in the area of energy conversion and storage, such as material for batteries will be highlighted. The study of small-scale mechanical phenomena in systems related to energy production, conversion or storage offer an enticing opportunity to materials scientists, who can provide new insight and investigate these phenomena with methods that have not previously been exploited.

  16. Bernard de Gordon (fl. 1270-1330): medieval physician and teacher.

    PubMed

    Pearn, John

    2013-02-01

    The Montpellier physician Bernard de Gordon flourished in the late Middle Ages in the era when university education first evolved in the training of European physicians. Fragmentary details of his life and medical influence are known from seven books, particularly his extensive (163 chapters) text Lilium Medicine and from Chaucer's reference to him in the Canterbury Tales. Chaucer lists Bernard de Gordon as one whose writings were part of the core curriculum of the best-trained European doctors of medieval Europe. Bernard de Gordon was one of that small group of medieval physicians who reverently followed Galenic lore which had endured for a thousand years yet who began to challenge its details and to experiment clinically with new methods of treatment. In his writings, Bernard de Gordon made the first reference to spectacles and to the hernial truss. His writings also contained detailed desiderata for the ethical best practice of medicine of his day, extending the principles of both Hippocrates and Haly ibn Abbas. Unlike many of the surviving writings of other medieval medical teachers, his texts have within them a tone of humility and acknowledged fallibility. Bernard de Gordon holds a small but significant place in the evolving pre-Renaissance chronology of medical professionalism.

    The objective of the Chemistry & Biology of Tetrapyrroles Gordon Conference is to bring together researchers from diverse disciplines that otherwise would not interact. By bringing biologists, chemists, engineers and clinicians with a common interest in tetrapyrroles the conference provides a forum for cross-disciplinary ideas and collaboration. The perspective provided by biologists, chemists, and clinicians working in fields such as newly discovered defects in human porphyrin metabolism, the myriad of strategies for light harvesting in photosynthetic organisms, novel tetrapyrroles that serve as auxiliary chromophores or enzyme cofactors, synthetic strategies in the design of novel tetrapyrrole scaffolds, and tetrapyrrole based cell signaling and regulatory systems, makes this conference unique in the field. Over the years the growing evidence for the role of tetrapyrroles and their reactive intermediates in cell signaling and regulation has been of increasing importance at this conference. The 2010 conference on Chemistry & Biology of Tetrapyrroles will focus on many of these new frontiers as outlined in the preliminary program listed. Speakers will emphasize unpublished results and new findings in the field. The oral sessions will be followed by the highly interactive afternoon poster sessions. The poster sessions provide all conferees with the opportunity to present their latest research and to exchange ideas in a more informal setting. As in the past, this opportunity will continue during the nightly social gathering that takes place in the poster hall following the evening lectures. All conferees are encouraged to submit and present posters. At the conference the best poster in the areas of biology, chemistry and medicine will be selected by a panel of previous conference chairs.

    2010-07-23

    The 2010 Gordon Conference on Radiation Chemistry will present cutting edge research regarding the study of radiation-induced chemical transformations. Radiation Chemistry or 'high energy' chemistry is primarily initiated by ionizing radiation: i.e. photons or particles with energy sufficient to create conduction band electrons and 'holes', excitons, ionic and neutral free radicals, highly excited states, and solvated electrons. These transients often interact or 'react' to form products vastly different than those produced under thermal equilibrium conditions. The non-equilibrium, non-thermal conditions driving radiation chemistry exist in plasmas, star-forming regions, the outer solar system, nuclear reactors, nuclear waste repositories, radiation-based medical/clinical treatment centers and in radiation/materials processing facilities. The 2010 conference has a strong interdisciplinary flavor with focus areas spanning (1) the fundamental physics and chemistry involved in ultrafast (atto/femtosecond) energy deposition events, (2) radiation-induced processes in biology (particularly spatially resolved studies), (3) radiation-induced modification of materials at the nanoscale and cosmic ray/x-ray mediated processes in planetary science/astrochemistry. While the conference concentrates on fundamental science, topical applied areas covered will also include nuclear power, materials/polymer processing, and clinical/radiation treatment in medicine. The Conference will bring together investigators at the forefront of their field, and will provide opportunities for junior scientists and graduate students to present work in poster format or as contributors to the Young Investigator session. The program and format provides excellent avenues to promote cross-disciplinary collaborations.

    Roberts syndrome and SC phocomelia syndrome are rare autosomal recessive genetic disorders representing the extremes of the spectrum of severity of the same condition, caused by mutations in ESCO2 gene. We report three new patients with Roberts syndrome from three unrelated consanguineous Egyptian families. All patients presented with growth retardation, mesomelic shortening of the limbs more in the upper than in the lower limbs and microcephaly. Patients were subjected to clinical, cytogenetic and radiologic examinations. Cytogenetic analysis showed the characteristic premature separation of centromeres and puffing of heterochromatic regions. Further, sequencing of the ESCO2 gene identified a novel mutation c.244_245dupCT (p.T83Pfs*20) in one family besides two previously reported mutations c.760_761insA (p.T254Nfs*27) and c.764_765delTT (p.F255Cfs*25). All mutations were in homozygous state, in exon 3. The severity of the mesomelic shortening of the limbs and craniofacial anomalies showed variability among patients. Interestingly, patient 1 had abnormal skin hypopigmentation. Serial fetal ultrasound examinations and measurements of long bones diagnosed two affected fetuses in two of the studied families. A literature review and case comparison was performed. In conclusion, we report a novel ESCO2 mutation and expand the clinical spectrum of Roberts syndrome.

  9. Alexander Gordon, puerperal sepsis, and modern theories of infection control--Semmelweis in perspective.

    PubMed

    Gould, Ian M

    2010-04-01

    Ignaz Semmelweis, a Hungarian doctor who practised in 19th century Vienna, is widely believed to be the father of modern infection control. He earned this accolade when he showed that puerperal sepsis was contagious and that it could be prevented with adequate hand hygiene. In fact, such ideas had circulated in the medical world for at least a century before Semmelweis' work. Moreover, it is well documented that Alexander Gordon, an obstetrician working in Aberdeen, UK, was the first to prove the contagious nature of puerperal sepsis. He also advocated the need for good hygiene for its prevention in a thesis published in 1795. This work described an epidemic of puerperal sepsis that began in Aberdeen in 1789. Gordon's thesis was reprinted three times in Edinburgh, Philadelphia, and London over the next 55 years, suggesting that Semmelweis (1847) could well have known of his work. Like Semmelweis, Gordon was persecuted for his findings.

    More than a university, Oral Roberts University in Tulsa, Oklahoma, was also the headquarters for evangelist Oral Roberts's electronic church. The electronic church in America, dominated by Christian evangelicals, used technology to spread the Gospel over radio airways and television signals to a dispersed audience. Yet evangelicals like Roberts also constructed ambitious campuses in real space and time. The architecture of Oral Roberts University visualized a modern and "populuxe" image for the electronic church in the 1960s and 1970s. The university's Prayer Tower purposely alluded to the Seattle Space Needle, aligning religion and the Space Age, and the campus's white, gold, and black color palette on late modern buildings created an image of aspirational luxury, conveying Roberts's health and wealth gospel. Oral Roberts University served as a sound stage for Roberts's radio and television shows, a pilgrimage point for his audience, and a university dedicated to training evangelicals in the electronic church.

    2015-11-01

    Using a generalization of the Madelung transformation, we derive the hydrodynamic representation of the Klein-Gordon-Einstein equations in the weak field limit. We consider a complex self-interacting scalar field with an arbitrary potential of the form V(|ϕ|2). We compare the results with simplified models in which the gravitational potential is introduced by hand in the Klein-Gordon equation, and assumed to satisfy a (generalized) Poisson equation. Nonrelativistic hydrodynamic equations based on the Schrodinger-Poisson equations or on the Gross-Pitaevskii-Poisson equations are recovered in the limit c → +∞.

    PubMed

    2014-10-01

    A method of averaging is applied to study the dynamics of a kink in the damped double sine-Gordon equation driven by both external (nonparametric) and parametric periodic forces at high frequencies. This theoretical approach leads to the study of a double sine-Gordon equation with an effective potential and an effective additive force. Direct numerical simulations show how the appearance of two connected π kinks and of an individual π kink can be controlled via the frequency. An anomalous negative mobility phenomenon is also predicted by theory and confirmed by simulations of the original equation.

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

    NASA Astrophysics Data System (ADS)

    Holzegel, Gustav; Smulevici, Jacques

    2013-01-01

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

    Chronic illness played a major role in the life and literary success of Robert Louis Stevenson. However, the exact nature of his chronic illness remains unclear. It is possible that Stevenson had hereditary hemorrhagic telangiectasia (Osler-Rendu-Weber Syndrome). This would explain his chronic respiratory complaints, recurrent episodes of pulmonary hemorrhage, and his death, at age 44 years, of probable cerebral hemorrhage. It would also explain his mother's hitherto unreported but apparent stroke, at age 38 years. Further support for this hypothesis might come from new details about the health of Stevenson and his relatives or from molecular analysis of tissue specimens remaining from him.

Staehle (center), high school student from Harley School, Rochester New York, talks with Steven Hall (advisor to Staehle) and Henry Floyd, both of the Marshall Space Flight Center (MSFC) about his experiment 'Behavior of Bacteria and Bacterial Spores in the Skylab Space Environment'. He was one of the 25 winners of a contest in which some 3,500 high school students proposed experiments for the following year's Skylab mission. Of the 25 students, 6 did not see their experiments conducted on Skylab because the experiments were not compatible with Skylab hardware and timelines. Of the 19 remaining, 11 experiments required the manufacture of equipment.

    After 34 years at NCI, Robert Wiltrout, Ph.D., said he is looking forward to trading his I-270 commute for another type of commute: exploring the waterways of Maryland, Alaska, and Wyoming to fulfill his love of fishing. Wiltrout officially retired as director of the NCI Center for Cancer Research (CCR) on July 2 of last year. Throughout his college academic career, Wiltrout had an interest in science, but it was not until he was working on a research project for his master’s degree that he considered a career in scientific research.

    The musicians are seen in daily neurological practice facing various problems sometimes simple such as skeletal or tendon pain or even compression of a nerve trunk and sometimes more complicated such as focal dystonia. Dystonia often has a dramatic impact on the career of a musician given the complexity of the clinical and therapeutic approach and the results are often disappointing. The history of the German Romantic composer Robert Schumann illustrates this reality; through his story a discussion of both the different pathophysiological hypotheses responsible for focal dystonia, a disorder of brain plasticity, and of the multimodal therapeutic approaches, revisited in the light of neurophysiological findings will be described.

    Robert Schumann (1810-1856) spent the last two-and-a-half years of his life in the private psychiatric hospital in Endenich. His medical records emerged in 1991 and were published by B. R. Appel in 2006. Daily entries document the treatment typical at that time for what was at first considered to be "melancholy with delusions": Shielding from stimuli, physical procedures, and a dietary regimen. The feared, actual diagnosis, a "general (incomplete) paralysis," becomes a certainty in the course of the paranoid-hallucinatory symptoms with cerebro-organic characteristics and agitated states, differences in pupil size, and increasing speech disturbances. In the medicine of the time, syphilis is just emerging as the suspected cause, and the term "progressive paralysis" is coined as typical for the course. Proof of the Treponema pallidum infection and the serologic reaction is not obtained until 1906. People close to Robert, in particular his wife Clara and the circle of friends around Brahms and Joachim, cared intensively for him and suffered under the therapeutic isolation. The medical records and illness-related letters contradict the theory that Schumann was disposed of by being put into the psychiatric hospital; they show the concern of all during the unfavorable illness course.

  2. The Science and Fiction of Robert L. Forward

    NASA Astrophysics Data System (ADS)

    Lundquist, Charles A.

    One way to examine a relationship between science and science fiction is to look at the works of individuals who simultaneously were practicing scientists and authors of science fiction. Dr. Robert L. Forward is such an individual. From 1980 through 1997 he wrote and published about twelve science fiction novels. During the same time interval, he produced many scientific and technical papers. Writing science fiction was essentially a byproduct of his scientific research. His early research concerned gravitation and astronomical objects. Later he studied space transportation technologies, including photon propelled sails, antimatter rockets and long tethers. An immediate observation is that Dr. Forward, in his science fiction, took particular care that the circumstances and technologies used had reasonable scientific bases. A prime example is his use of antimatter propulsion in his fiction. In his scientific career, Dr. Forward was a leading proponent that antimatter propulsion was possible, but very expensive. Enormous sails propelled in space by astronomical photons or laser beams is another propulsion technology employed in his novels. If a distinction is made between fiction based on sound scientific principles and fiction that is pure fantasy, the works of Robert Forward clearly fall in the first grouping.

    The duck-billed platypus, or Ornithorhynchus, was the subject of an intense debate among natural historians in the late eighteenth and early nineteenth centuries. Its paradoxical mixture of mammalian, avian and reptilian characteristics made it something of a taxonomic conundrum. In the early 1820s Robert Jameson (1774-1854), the professor of natural history at the University of Edinburgh and the curator of the University's natural history museum, was able to acquire three valuable specimens of this species. He passed one of these on to the anatomist Robert Knox (1791-1862), who dissected the animal and presented his results in a series of papers to the Wernerian Natural History Society, which later published them in its Memoirs. This paper takes Jameson's platypus as a case study on how natural history specimens were used to create and contest knowledge of the natural world in the early nineteenth century, at a time when interpretations of the relationships between animal taxa were in a state of flux. It shows how Jameson used his possession of this interesting specimen to provide a valuable opportunity for his protégé Knox while also helping to consolidate his own position as a key figure in early nineteenth-century natural history.

    In 1665, Robert Hooke published his major work in microscopy, Micrographia, a defense of experimental philosophy. The following year, Margaret Cavendish, Duchess of Newcastle, published at her own expense a treatise and a novel that undermined the basis of this new science. The dispute broke out at the initiative of the Duchess, in the context of a vast controversy about the legitimacy and the efficiency of optical instruments in natural philosophy. All the figures of the dual are used, except one: the counterattack. Cavendish, indeed, was alone on the battlefield. Is it possible to call a dual a battle with only one combatant? This particular case of dispute that stops owing to the shortage of combatants is the subject of this article.

  11. Johnson-Kendall-Roberts adhesive contact for a toroidal indenter

    The unilateral axisymmetric frictionless adhesive contact problem for a toroidal indenter and an elastic half-space is considered in the framework of the Johnson-Kendall-Roberts theory. In the case of a semi-fixed annular contact area, when one of the contact radii is fixed, while the other varies during indentation, we obtain the asymptotic solution of the adhesive contact problem based on the solution of the corresponding unilateral non-adhesive contact problem. In particular, the adhesive contact problem for Barber's concave indenter is considered in detail. In the case when both contact radii are variable, we construct the leading-order asymptotic solution for a narrow annular contact area. It is found that for a v-shaped generalized toroidal indenter, the pull-off force is independent of the elastic properties of the indented solid.

    The overwhelming majority of important papers in physics are written by physicists. But the physician Julius Robert Mayer (1814-1878, see photo) did a valid theoretical calculation of the mechanical equivalent of heat just before Joule reported on his results from his well-known paddle-wheel experiments. Joule is well-known to physics people and Mayer is a relatively obscure and unknown name. Joule was part of the physics establishment; Mayer was not. Joule's paddle-wheel experiments were easy to understand, and physics people appreciated the painstaking manner in which he made corrections in his experiments. The fame of Joule is well-deserved. On the other hand, Mayer's work is not traditional and there will almost certainly never be a Mayer physics laboratory experiment. We can admire the tenacity with which Mayer pushed his priority case, but that is all.

  14. Hooke's figurations: a figural drawing attributed to Robert Hooke.

    The experimental philosopher Robert Hooke (1635-1703) is known to have apprenticed to the leading painter Peter Lely on his first arrival in London in the late 1640s. Yet the relevance of Hooke's artistic training to his mature draughtsmanship and identity has remained unclear. Shedding light on that larger interpretive problem, this article argues for the attribution to Hooke of a figural drawing now in Tate Britain (T10678). This attributed drawing is especially interesting because it depicts human subjects and bears Hooke's name functioning as an artistic signature, both highly unusual features for his draughtsmanship. From evidence of how this drawing was collected and physically placed alongside images by leading artists in the early eighteenth century, I suggest how it can offer new insight into the reception of Hooke and his graphic work in the early Enlightenment.

    We present several novel examples of an extension of the Quispel-Roberts-Thompson (QRT) mapping in which the coefficients are periodic functions of the independent variable and we prove that for period 2 this extension includes all so-called asymmetric QRT mappings. We establish the integrability of these new mappings by explicitly constructing rational invariants for them, which can be parametrised in terms of elliptic functions. Moreover, we show that the correspondences induced by these conserved quantities are all integrable - i.e., exhibit polynomial growth of the number of images they produce - and we present a conjecture pertaining to the degree of the growth. The case of Hirota-Kimura-Yahagi mappings and their associated correspondences is examined as well and we give examples of integrable correspondences associated with such mappings.

    Robert Heath Lock (1879–1915), a Cambridge botanist associated with William Bateson and R. C. Punnett, published his book Recent Progress in the Study of Variation, Heredity, and Evolution in 1906. This was a remarkable textbook of genetics for one appearing so early in the Mendelian era. It covered not only Mendelism but evolution, natural selection, biometry, mutation, and cytology. It ran to five editions but was, despite its success, largely forgotten following Lock’s early death in 1915. Nevertheless it was the book that inspired H. J. Muller to do genetics and was remembered by A. H. Sturtevant as the source of the earliest suggestion that linkage might be related to the exchange of parts between homologous chromosomes. Here we also put forward evidence that it had a major influence on the statistician and geneticist R. A. Fisher at the time he was a mathematics student at Cambridge. PMID:23824968

    The widespread use of the term Systems Biology (SB) signals a welcome recognition that organisms must be understood as integrated systems. Although just what this is taken to mean varies from one group to another, it generally implies a focus on biological functions and processes rather than on biological parts and a reliance on mathematical modeling to arrive at an understanding of these biological processes based on biological observations or measurements. SB, thus, falls directly in the line of reflection carried out by Robert Rosen throughout his work. In the present article, we briefly introduce the various currents of SB and then point out several ways Rosen's work can be used to avoid certain pitfalls associated with the use of dynamical systems models for the study of complex systems, as well as to inspire a productive path forward based on loosely organized cooperation among dispersed laboratories.

    Dr. Robert K. Crane made major contributions to our understanding of carbohydrate metabolism and transport of the intestine over a very long and productive career. This Perspective examines, briefly, his early life and academic positions, but more importantly, this Perspective highlights his contributions to the understanding of coupled Na+-glucose absorption by the small intestine. I discuss how his early hypothesis of a “cotransport” of sodium and glucose ushered in and provided the physiological explanation for the clinical treatment of acute diarrhea and cholera when using oral rehydration therapy (ORT). ORT saves millions of lives each year. Certainly, humankind is better off because of Crane's hypothesis of the Na+-glucose cotransporter that he put forth over 50 years ago? PMID:23525627

    1993-01-01

    In his letter on page 13 of the March 1993 issue, Robert Yaes raised the question of whether the existence of the cosmic microwave background (CMB), now observed so precisely with COBE, is compatible with the principle of relativity: The laws by which the states of physical systems undergo change are not affected, whether these changes of state be referred to the one or other of two systems of coordinates in uniform translatory motion. Although I do not claim to provide an xpertresponse to this question, as desired by Yaes, it is my understanding that the principle of relativity is not necessarily violated by the mere existence of a universal reference frame. The laws of physics can still be invariant under some transformation of coordinates. This transformation is not specified by the principle of relativity itself, although we have discovered so far that Nature respects Lorentz invariance (principle of the constancy of the velocity of light).

  1. Robert Hooke: early respiratory physiologist, polymath, and mechanical genius.

    West, John B

    2014-07-01

    Robert Hooke (1635-1703) was a polymath who made important contributions to respiratory physiology and many other scientific areas. With Robert Boyle, he constructed the first air pump that allowed measurements on small animals at a reduced atmospheric pressure, and this started the discipline of high-altitude physiology. He also built the first human low-pressure chamber and described his experiences when the pressure was reduced to the equivalent of an altitude of ∼2,400 m. Using artificial ventilation in an animal preparation, he demonstrated that movement of the lung was not essential for life. His book Micrographia describing early studies with a microscope remains a classic. He produced an exquisite drawing of the head of a fly, showing the elaborate compound eye. There is also a detailed drawing of a flea, and Hooke noted how the long, many-jointed legs enable the insect to jump so high. For 40 years, he was the curator of experiments for the newly founded Royal Society in London and contributed greatly to its intellectual ferment. His mechanical inventions covered an enormous range, including the watch spring, the wheel barometer, and the universal joint. Following the Great Fire of London in 1666, he designed many of the new buildings in conjunction with Christopher Wren. Unfortunately, Hooke had an abrasive personality, which was partly responsible for a lack of recognition of his work for many years. However, during the last 25 years, there has been renewed interest, and he is now recognized as a brilliant scientist and innovator.

    Photochemistry has wide implications on fundamental science with technological applications that range from synthetic and mechanistic organic and inorganic chemistry to sensing/manipulation in the biological sciences to viable solar energy conversion assemblies. The 2011 Gordon Research Conference on Photochemistry will highlight recent advances on photochemical reactions, their mechanisms, spectroscopic techniques and applications to materials, organic synthesis, and biology. The conference will continue its long tradition on dynamic discussions on recent advances and unsolved scientific problems. The format of lectures, poster presentations and informal discussions provides an ideal venue for students and post-doctoral fellows to interact with the leaders in the field. These junior scientists will have an opportunity to participate in the Gordon Research Seminar on Photochemistry to be held prior to the GRC. The GRS will focus on photochemical aspects of solar energy conversion. Four abstracts for posters at the GRC and presentations at the GRS will be selected as short talks at the GRC.

    The concept of nonlinear self-adjointness, introduced by Ibragimov, has significantly extends approaches to constructing conservation laws associated with symmetries since it incorporates the strict self-adjointness, the quasi self-adjointness as well as the usual linear self-adjointness. Using this concept, the nonlinear self-adjointness condition for the Klein-Gordon-Fock equation was established and subsequently used to construct simplified but infinitely many nontrivial and independent conserved vectors. The Noether's theorem was further applied to the Klein-Gordon-Fock equation to explore more distinct first integrals, result shows that conservation laws constructed through this approach are exactly the same as those obtained under strict self-adjointness of Ibragimov's method.

  14. Quantum quenches in the sinh-Gordon model: steady state and one-point correlation functions

    We consider quantum quenches to the sinh-Gordon integrable quantum field theory from a particular class of initial states. Our analysis includes the case of mass and interaction quenches starting from a non-interacting theory. By means of the recently developed quench action method, we fully characterize the stationary state reached at long times after the quench in terms of the corresponding rapidity distribution. We also provide exact results for the expectation values of arbitrary vertex operators in the post-quench stationary state by proposing a formula based on the analogy with the standard thermodynamic Bethe ansatz. Finally, we comment on the behavior of the post-quench stationary state under the mapping between the sinh-Gordon field theory and the one-dimensional Lieb-Liniger model.

    1986-01-01

    The generalized wave equation and generalized sine-Gordon equations are known to be natural multidimensional differential geometric generalizations of the classical two-dimensional versions. In this paper, a system of linear differential equations is associated with these equations, and it is shown how the direct and inverse problems can be solved for appropriately decaying data on suitable lines. An initial-boundary value problem is solved for these equations.

    This study base on dark soliton solutions of Klein-Gordon-Zakharov (KGZ) equation in (1+2) dimensions. The generalized Kudryashov method (GKM) which is one of the analytical methods has been handled for finding exact solutions of KGZ equation in (1+2) dimensions. By using this method, dark soliton solutions of this equation have been obtained. Also, by using Mathematica Release 9, some graphical simulations were done to see the behavior of these solutions.

    2007-12-01

    In a recent paper by Barton [G. Barton, J. Phys. A: Math. Gen. 40 (2007) 1011], the 1-dimensional Klein Gordon equation was solved analytically for the non-singular Coulomb-like potential V(|x|)=-α/(|x|+a). In the present Letter, these results are completely confirmed by a numerical formulation that also allows a solution for an alternative cut-off Coulomb potential V(|x|)=-α/|x|, |x|>a, and otherwise V(|x|)=-α/a.

  18. Algebraic approach to form factors in the complex sinh-Gordon theory

    2017-01-01

    We study form factors of the quantum complex sinh-Gordon theory in the algebraic approach. In the case of exponential fields the form factors can be obtained from the known form factors of the ZN-symmetric Ising model. The algebraic construction also provides an Ansatz for form factors of descendant operators. We obtain generating functions of such form factors and establish their main properties: the cluster factorization and reflection equations.

    The notion of four-rapidity is defined as a four-vector with one time-like and three space-like coordinates. It is proved, the energy and momentum defined in the space of four-rapidity obey Klein-Gordon equations constrained by the classical trajectory of a relativistic particle. It is shown, for small values of a proper mass influence of the constraint is weakened and the classical motion gains features of a wave motion.

    In this note, I generalized the Klein-Gordon and the Dirac equations by using Suykens's nonlocal-in-time kinetic energy approach, which is motivated from Feynman's kinetic energy functional formalism where the position differences are shifted with respect to one another. I proved that these generalized equations are similar to those obtained in literature in the presence of minimal length based on the Quesne-Tkachuk algebra.

  3. Archetypal Dreams: the Quantum Theater of Robert Wilson

    NASA Astrophysics Data System (ADS)

    Dietrich, Dawn Yvette

    1992-01-01

    My topic is situated within the larger framework of interdisciplinary study currently exploring the impact of new physics on various "soft" disciplines and sciences. Aligning myself with thinkers like Fritjof Capra and N. Katherine Hayles, who argue that quantum mechanics has brought about a new paradigm for the conceptualization of the physical world and our relation to it, I demonstrate that there is a connection, a kind of cultural translation, which relates contemporary physics to some avant-garde theater. Specifically, I center my research on American theater designer, Robert Wilson, who, recognized for his manipulation of the formal elements of stagecraft, owes much to the reconstruction of principles governing space and time. Taken further, I maintain that it is through the paradigm established from relativity theory and quantum mechanics that Wilson experiments with the elementary "forces" of the theater itself. This "restructuring" occurs through the dramatist's conceptions of space and time and the relation of those properties to both performers and spectators. Unlike most conventional theater, but as in many contemporary visual arts, time is manipulated through spatial metaphors and events take place in an amplified space--effecting a kind of dramatic space/time. Through manipulation of scale, the exploration of discontinuous time, and segregated stage zones, Wilson demonstrates that theater time is fluid and that it is not necessary for dramatic action to take place within the unified stage space delineated by the proscenium itself. Unlike conventional theater, where the stage is constructed with one perspective in mind, Wilson's theatrical mise-en-scene--a kind of new "perceptual field"--requires "imaginative watching"; that is, more perceptual discrimination from the audience who must sort and organize the visual material, highlighting the essential while reconfiguring the incidental. And this is where the myth is born, where archetypal dreams stir

    Robert Van Hook, who served as AGU's interim executive director since January 2009, led the organization during a transition period that began with the retirement of long-serving executive director A. F. (“Fred”) Spilhaus Jr. Van Hook's tenure concluded on 30 August when Christine McEntee assumed her position as AGU's new executive director (see Eos, 91(17), 153, 156, 2010). During his tenure at AGU, which overlapped with a global economic recession, Van Hook helped to guide the organization through key structural governance changes, strategic planning, and upgrades in technology, human resources, and accounting. He also helped to revitalize public outreach and member services, among many other efforts. Van Hook, president of Transition Management Consulting, recently reflected upon his tenure, the transition period, and the future of AGU. Van Hook credits AGU's strong volunteer leadership—including past presidents Tim Killeen and Tim Grove, current president Mike McPhaden, and president-elect Carol Finn—for courage in moving the organization through a successful transition. “They were the ones who shoved the boat off from the shore. I was lucky enough to be invited into the boat,” he said. He also credits the staff for their resiliency and commitment to supporting AGU's science.

  6. Robert Apfel's contribution to clinical diagnostic ultrasound: The mechanical index

    NASA Astrophysics Data System (ADS)

    Holland, Christy K.

    2004-05-01

    The mechanical index, MI, resulted from theoretical considerations of the short-pulse acoustic threshold for inertial cavitation in water populated with microbubbles of all sizes [R. E. Apfel and C. K. Holland, Ultrasound Med Biol. 17, 179-185 (1991)]. In this review, the onset of cavitation will be discussed with reference to Robert Apfel's legacy of theoretical and experimental data. The questions arise: Can the utility of the MI be extended to situations in which the threshold MI is exceeded, thereby allowing for some estimate of the quantification of a potential bioeffect due to microcavitation? Also, can the MI be extended to situations in which pulses are, unlike the original formulation, not short? Is there a theoretical or semi-empirical basis for the MI threshold below which cavitation is unlikely? Can the MI be used to predict gas contrast agent destruction? The possible consequences of gas body activation associated with aerated lung tissue, intestinal gas pockets or encapsulated gas contrast agents represent specific instances of cavitation considerations relevant to clinical practice. Monitoring the real-time display of the MI (mandated by the FDA) helps clinicians evaluate and minimize the potential risks in the use of diagnostic ultrasound instrumentation.

    An important ongoing question for higher education is how to successfully mentor the next generation of scientists and engineers. It has been my privilege to have been mentored by one of the best, Dr Robert F. Wagner and his colleagues at the CDRH/FDA during the mid 1980s. Bob introduced many of us in medical ultrasonics to statistical imaging techniques. These ideas continue to broadly influence studies on adaptive aperture management (beamforming, speckle suppression, compounding), tissue characterization (texture features, Rayleigh/Rician statistics, scatterer size and number density estimators), and fundamental questions about how limitations of the human eye-brain system for extracting information from textured images can motivate image processing. He adapted the classical techniques of signal detection theory to coherent imaging systems that, for the first time in ultrasonics, related common engineering metrics for image quality to task-based clinical performance. This talk summarizes my wonderfully-exciting three years with Bob as I watched him explore topics in statistical image analysis that formed a rational basis for many of the signal processing techniques used in commercial systems today. It is a story of an exciting time in medical ultrasonics, and of how a sparkling personality guided and motivated the development of junior scientists who flocked around him in admiration and amazement.

  8. Composition and adaptation in the life of Robert Schumann.

    2005-01-01

    The composer Robert Schumann, who suffered from bipolar disorder, utilized his impressive musical and literary talents in attempts to adapt to multiple developmental traumas, separations, and losses as well as to the ongoing ravages of his mood disorder. By analyzing several of his Lieder, the author formulates and describes several defense mechanisms involved in these adaptations. These include identification with the lost object, the use of transitional objects and phenomena, sublimation, denial, minimization, idealization, playfulness, and the employment of healthy obsessive traits. Schumann utilized these adaptive defenses successfully for a brief period, thus coping with a difficult separation from his fiancée, Clara. Ultimately, however, he was unable to experience mature mourning regarding the deaths of several family members. The author, drawing on his extensive experience with treating bipolar individuals in outpatient settings, discusses some of the difficulties that many bipolar patients like Schumann have with mourning, including early developmental vulnerabilities to separation and loss, the disorganizing effects of bipolar mood episodes on cognition and self-coherence, the need to camouflage affects reminiscent of bipolar mood episodes, and experiencing these affects and mood episodes as traumatic reoccurrences. By studying the biographies of creative individuals such as Schumann, clinicians can expand their appreciation of their patients' adaptive capacities and thus assist them in restoring a sense of hope and vitality in their lives.

  9. On "Telepathic dreams?": an unpublished paper by Robert J. Stoller.

    2001-01-01

    In 1973 Robert Stoller wrote a paper on a series of dreams-his own and his patients'--that he reluctantly found himself calling "telepathic." He never submitted the paper for publication, though he returned to the topic of unconscious communication and telepathy with increasing fascination in the years before his death. Publication of Stoller's paper seems particularly opportune just now. In it he pleads for open-minded examination of data, however alien to current scientific belief those data seem. In the past, despite numerous published reports of possibly telepathic experiences in analysis, their investigation remained relatively one-sided, since a technical posture of anonymity with patients constrained analysts from revealing that a communication struck them as telepathic. This has limited what analysts have been able to learn about the information actually exchanged, how it was exchanged, and whether the communication was experienced as uncanny by the patient. Recent attention to the intersubjective nature of the analytic situation has led to a deemphasis of anonymity, opening freer dialogue that may facilitate the rigorous investigation Stoller calls for. Such investigation may further analytic understanding of unconscious mental function and communication in the clinical setting, and lend perspective to the growing body of carefully controlled experimental research on anomalous mental phenomena.

  10. 1987 Robert E. Horton Award to Thomas Dunne

    NASA Astrophysics Data System (ADS)

    Dunne, Thomas

    Robert Horton demonstrated in his seminal 1945 paper that physically based quantitative models for landscape evolution can be constructed by using predicted overland flow in a sediment transport equation for sheetwash. He envisioned drainage network evolution by infiltration-limited overland flow as a process of channel incision, network growth, and then abstraction to a stable channel network fed by hillslopes too short for channel initiation. Not until the work of Tom Dunne in the late 1960s in the Sleepers River watershed, Vermont, was it realized that overland flow, and consequently hillslope evolution, could occur by an entirely different mechanism than that proposed by Horton. Dunne showed that in certain predictable zones of the landscape, exfiltration from saturated grounds adds to precipitation on the soil surface to form what he later called saturation overland flow. Many researchers have since found that this form of overland flow occurs in humid and semiarid landscapes throughout the world. So clear is Dunne's contribution to defining this process that some refer to it as the “Dunne mechanism” to distinguish it from “Horton overland flow.” His work also documented unquestionably the applicability of the partial area concept in explaining runoff generation. Because of this work, his research in snowmelt runoff, and his subsequent authorship with Luna Leopold of the widely used book entitled Water in Environmental Planning, Dunne has established himself as a leader of process hydrology.

  11. Roberts syndrome: New evidence supporting an altered metaphase chromatin structure

    Roberts syndrome is a rare autosomal recessive disease clinically manifested in the newborn by mental and growth retardation, tetraphocomelia, and a variety of craniofacial abnormalities. Cell lines derived from RS patients exhibit subtle mutagen hypersensitivity and cytogenetic abnormalities which include random chromosome loss and the splaying of heterochromatic chromosomal regions. The latter, typically detected on C-banded metaphases, has been used prenatally for the diagnosis of RS. To gain further insights into the RS defect, we have examined a number of parameters related to metaphase chromatin structure, with observations as follows. (1) The heterochromatic splaying associated with RS was found to be visible on G- as well as C-banded metaphases. (2) Quantitative evaluations using fluorescence image analysis revealed that RS metaphase chromosomes bind DAPI less efficiently than chromosomes from normal cells. (3) Denaturation of chromosomal DNA with either a C-banding procedure or 70% formamide at 70{degree}C each produced an aberrant hybridization pattern on RS chromosomes in FISH experiments employing biotinylated total human DNA as probe. (4) RS cells exhibited a >3-fold increase in sensitivity to VM-26, a potent inhibitor of topoisomerase II. Collectively, the aforementioned data support the notion that the primary defect in RS results in an altered metaphase chromatin structure.

    The Roman Catholic Church reacted negatively to the announcement that the Nobel Prize for Medicine had been awarded to Robert G Edwards. Thirty-three years ago, Cardinal Albino Luciani, on the eve of his election to become Pope, stated that, whereas progress is certainly a beautiful thing, mankind has not always benefited from progress. Catholic criticism has raised seven points: (i) God wants human life to begin through the 'conjugal act' and not artificially; (ii) artificial interventions at the beginning of human life are dangerous and ethically unacceptable; (iii) limits can be imposed even upon an individual's freedom to achieve a legitimate goal, such as having a child within marriage; (iv) the massive loss of preimplantation embryos characterizing IVF must be considered as a tragic loss of 'nascent' human persons; (v) Edwards bears a moral responsibility for all subsequent developments in assisted reproduction technology and for all 'abuses' made possible by IVF; (vi) there can be deleterious consequences for offspring of assisted reproduction technology; and (vii) Edwards' discovery did not eliminate the causes of infertility. This article elaborates from the Roman Catholic perspective on each of these points, some of which are found to be more substantial than others.

    In 1999, the U.S. Geological Survey, in cooperation with the U.S. Army Signal Center and Fort Gordon, began collection of periodic streamflow data at four streams on the military base to assess and estimate streamflow characteristics of those streams for potential water-supply sources. Simple and reliable methods of determining streamflow characteristics of selected streams on the military base are needed for the initial implementation of the Fort Gordon Integrated Natural Resources Management Plan. Long-term streamflow data from the Butler Creek streamflow gaging station were used along with several concurrent discharge measurements made at three selected partial-record streamflow stations on Fort Gordon to determine selected low-flow streamflow characteristics. Streamflow data were collected and analyzed using standard U.S. Geological Survey methods and computer application programs to verify the use of simple drainage area to discharge ratios, which were used to estimate the low-flow characteristics for the selected streams. Low-flow data computed based on daily mean streamflow include: mean discharges for consecutive 1-, 3-, 7-, 14-, and 30-day period and low-flow estimates of 7Q10, 30Q2, 60Q2, and 90Q2 recurrence intervals. Flow-duration data also were determined for the 10-, 30-, 50-, 70-, and 90-percent exceedence flows. Preliminary analyses of the streamflow indicate that the flow duration and selected low-flow statistics for the selected streams averages from about 0.15 to 2.27 cubic feet per square mile. The long-term gaged streamflow data indicate that the streamflow conditions for the period analyzed were in the 50- to 90-percent flow range, or in which streamflow would be exceeded about 50 to 90 percent of the time.

    We discuss the Klein–Gordon (KG) equation using a path-integral approach in 5D space–time. We explicitly show that the KG equation in flat space–time admits a consistent probabilistic interpretation with positively defined probability density. However, the probabilistic interpretation is not covariant. In the non-relativistic limit, the formalism reduces naturally to that of the Schrödinger equation. We further discuss other interpretations of the KG equation (and their non-relativistic limits) resulting from the 5D space–time picture. Finally, we apply our results to the problem of hydrogenic spectra and calculate the canonical sum of the hydrogenic atom.

    We investigate superfluidity, and the mechanism for creation of quantized vortices, in the relativistic regime. The general framework is a nonlinear Klein-Gordon equation in curved spacetime for a complex scalar field, whose phase dynamics gives rise to superfluidity. The mechanisms discussed are local inertial forces (Coriolis and centrifugal), and current-current interaction with an external source. The primary application is to cosmology, but we also discuss the reduction to the nonrelativistic nonlinear Schrödinger equation, which is widely used in describing superfluidity and vorticity in liquid helium and cold-trapped atomic gases.

    Classical thermodynamics of the (1+1)-dimensional asymmetric double sinh-Gordon system is investigated. The pseudo-Schrödinger equation resulting from the transfer integral method is solved numerically and within the semiclassical approximation; the exact results are also given at several temperatures. It is found that the specific heat exhibits a characteristic hump resembling a similar one observed in the systems with a symmetric potential; in some structures, extremely narrow and extremely high peak is developed. The interpretation for this behavior is given.

    We study the double-sine-Gordon kink-kink collisions in a formalism which employs collective variables to describe the internal oscillations of the kinks and their translational motion in their center-of-mass frame. The equations of motion are solved in the absence of the radiation field and dynamical dressing and the results are compared with numerical molecular-dynamics simulations. We investigate the energy exchange between the translational and internal modes, and a mechanism is proposed to explain the values of the translational velocity at which maximum energy is exchanged between the two modes.

    SciTech Connect

    Cuenda, Sara; Sanchez, Angel

    2005-06-01

    Working within the framework of nonlinear Klein-Gordon models as a paradigmatic example, we show that length scale competition, an instability of solitons subjected to perturbations of an specific length, can be understood by means of a collective coordinate approach in terms of soliton position and width. As a consequence, we provide a natural explanation of the phenomenon in much simpler terms than any previous treatment of the problem. Our technique allows us to study the existence of length scale competition in most soliton bearing nonlinear models and can be extended to coherent structures with more degrees of freedom.

    We derive the exact mass-coupling relation of the simplest multiscale quantum integrable model, i.e., the homogeneous sine-Gordon model with two mass scales. The relation is obtained by comparing the perturbed conformal field theory description of the model valid at short distances to the large distance bootstrap description based on the model's integrability. In particular, we find a differential equation for the relation by constructing conserved tensor currents, which satisfy a generalization of the Θ sum rule Ward identity. The mass-coupling relation is written in terms of hypergeometric functions.

    We investigate the stochastic bifurcation of a damped sine-Gordon equation with Dirichlet boundary conditions under the influence of multiplicative Gaussian white noise. Introducing a slow time scale, we derive the amplitude equations near the trivial solution by multiscale analysis. And the stationary probability density functions are formulated analytically using the stochastic averaging of energy envelope. The numerical calculations show that the system undergoes a stochastic D-bifurcation of energy envelope from a delta measure to new stationary measures when the control parameter crosses a critical point.

    It is shown that for a one-dimensional Schrödinger operator with a potential whose first moment is integrable the elements of the scattering matrix are in the unital Wiener algebra of functions with integrable Fourier transforms. This is then used to derive dispersion estimates for solutions of the associated Schrödinger and Klein-Gordon equations. In particular, the additional decay conditions are removed in the case where a resonance is present at the edge of the continuous spectrum. Bibliography: 29 titles.

    Roberts Bank, part of the Fraser River delta system on Canada's Pacific coast, is a dynamic estuarine environment supporting important fisheries as well as internationally significant populations of migratory shorebirds. The 8000 ha bank environment comprises a complex of riparian boundaries, intertidal marshes, mud and sand flats, eelgrass meadows, macroalgae and biofilms. Anthropogenic developments (a ferry causeway in 1961 and a port causeway in 1969) have been responsible for changes in tidal flow patterns, tidal elevation, sediment transport and the net expansion of eelgrass beds. The goals of the present study were to (1) directly compare geotechnical properties spanning each side of the coalport causeway, and (2) enhance our understanding of the intercauseway ecosystem under a high-resolution sampling design. Sediment properties (grain size, porosity, organic content, and chlorophyll) and biological communities (eelgrass, macrofauna (0.5-1.0 mm) and meiofauna (0.063-0.5 mm)) were surveyed in 1997 at three stations outside the intercauseway area and three lateral transects spanning the intercauseway tidal flat at tidal heights representing three different habitats: biofilm, Zostera japonica, and Zostera marina. A fine-silt organic-rich porous deposit was observed on the shoreward north side of the coalport causeway relative to the south counterpart, suggesting that consolidation and erosion processes could likely not keep pace with the deposition of Fraser River silt. High chlorophyll levels were found in the protected shoreward northern border of the ferry causeway where fine sands dominate and higher water transparency exists, owing to the redirection of the silt-laden river plume by the coalport causeway. Principle Components Analysis revealed a positive relationship between these porous, organic-rich sediments and cumacean abundance in all regions where eelgrass was absent, including the north side of the coalport causeway.

    This Conference will examine DNA repair as the key component in genomic surveillance that is so crucial to the overall integrity and function of mammalian cells. Recent discoveries have catapulted the field of DNA repair into a pivotal position for fundamental investigations into oncology, aging, environmental health, and developmental biology. We hope to highlight the most promising and exciting avenues of research in robust discussions at this conference. This Mammalian DNA Repair Gordon Conference differs from the past conferences in this series, in which the programs were broader in scope, with respect to topics and biological systems covered. A conference sponsored by the Genetics Society in April 1998 emphasized recombinational mechanisms for double-strand break repair and the role of mismatch repair deficiency in colorectal cancer. These topics will therefore receive somewhat less emphasis in the upcoming Conference. In view of the recent mechanistic advances in mammalian DNA repair, an upcoming comprehensive DNA repair meeting next autumn at Hilton Head; and the limited enrollment for Gordon Conferences we have decided to focus session-by-session on particular areas of controversy and/or new developments specifically in mammalian systems. Thus, the principal presentations will draw upon results from other cellular systems only to the extent that they impact our understanding of mammalian DNA repair.

  1. Nonlinear quantum-mechanical system associated with Sine-Gordon equation in (1 + 2) dimensions

    SciTech Connect

    2014-10-15

    Despite the fact that it is not integrable, the (1 + 2)-dimensional Sine-Gordon equation has N-soliton solutions, whose velocities are lower than the speed of light (c = 1), for all N ≥ 1. Based on these solutions, a quantum-mechanical system is constructed over a Fock space of particles. The coordinate of each particle is an angle around the unit circle. U, a nonlinear functional of the particle number-operators, which obeys the Sine-Gordon equation in (1 + 2) dimensions, is constructed. Its eigenvalues on N-particle states in the Fock space are the slower-than-light, N-soliton solutions of the equation. A projection operator (a nonlinear functional of U), which vanishes on the single-particle subspace, is a mass-density generator. Its eigenvalues on multi-particle states play the role of the mass density of structures that emulate free, spatially extended, relativistic particles. The simplicity of the quantum-mechanical system allows for the incorporation of perturbations with particle interactions, which have the capacity to “annihilate” and “create” solitons – an effect that does not have an analog in perturbed classical nonlinear evolution equations.

    For any cosmological constant {Λ = -3/ℓ2 < 0} and any {α < 9/4}, we find a Kerr-AdS spacetime {({M}, g_{KAdS})}, in which the Klein-Gordon equation {Box_{g_{KAdS}}ψ + α/ℓ2ψ = 0} has an exponentially growing mode solution satisfying a Dirichlet boundary condition at infinity. The spacetime violates the Hawking-Reall bound {r+2 > |a|ℓ}. We obtain an analogous result for Neumann boundary conditions if {5/4 < α < 9/4}. Moreover, in the Dirichlet case, one can prove that, for any Kerr-AdS spacetime violating the Hawking-Reall bound, there exists an open family of masses {α} such that the corresponding Klein-Gordon equation permits exponentially growing mode solutions. Our result adopts methods of Shlapentokh-Rothman developed in (Commun. Math. Phys. 329:859-891, 2014) and provides the first rigorous construction of a superradiant instability for negative cosmological constant.

    In this paper, we present efficient, unconditionally stable and accurate numerical methods for approximations of the Klein-Gordon-Schroedinger (KGS) equations with/without damping terms. The key features of our methods are based on: (i) the application of a time-splitting spectral discretization for a Schroedinger-type equation in KGS (ii) the utilization of Fourier pseudospectral discretization for spatial derivatives in the Klein-Gordon equation in KGS (iii) the adoption of solving the ordinary differential equations (ODEs) in phase space analytically under appropriate chosen transmission conditions between different time intervals or applying Crank-Nicolson/leap-frog for linear/nonlinear terms for time derivatives. The numerical methods are either explicit or implicit but can be solved explicitly, unconditionally stable, and of spectral accuracy in space and second-order accuracy in time. Moreover, they are time reversible and time transverse invariant when there is no damping terms in KGS, conserve (or keep the same decay rate of) the wave energy as that in KGS without (or with a linear) damping term, keep the same dynamics of the mean value of the meson field, and give exact results for the plane-wave solution. Extensive numerical tests are presented to confirm the above properties of our numerical methods for KGS. Finally, the methods are applied to study solitary-wave collisions in one dimension (1D), as well as dynamics of a 2D problem in KGS.

    Public Law 99-190 requires the Department of Defense to increase the use of coal at its facilities in the United States. This study investigated the feasibility of converting oil- and gas-fired heating plants to coal firing at four Army installations: Fort Bragg, NC; Fort Campbell, KY; Fort Gordon, GA; and Picatinny Arsenal, NJ. Information on the energy systems at the selected sites was gathered by site visit and survey, and project life cycle cost (LCC) was computationally estimated. The study concluded that, for the four installations, there would be a lower life-cycle cost (LCC) in maintaining the status quo than in building new plants. However, where new plant construction is planned, the larger the plants, the better its potential for cost-effectively using coal as a plant fuel. The use of coal at a new plant at Fort Bragg was found to be more cost effective than gas or oil, and may result in significant cost savings. For the other three installations studied, significant price increases in alternate fuels would be required before coal would become economically feasible (31 to 73 percent for gas, and 50 to 84 percent for 6 fuel oil).

    2016-07-01

    Using the coherent state functional integral expression of the partition function, we show that the sine-Gordon model on an analogue curved spacetime arises as the effective quantum field theory for phase fluctuations of a weakly imperfect Bose gas on an incompressible background superfluid flow when these fluctuations are restricted to a subspace of the single-particle Hilbert space. We consider bipartitions of the single-particle Hilbert space relevant to experiments on ultracold bosonic atomic or molecular gases, including, e.g., restriction to high- or low-energy sectors of the dynamics and spatial bipartition corresponding to tunnel-coupled planar Bose gases. By assuming full unitary quantum control in the low-energy subspace of a trapped gas, we show that (1) appropriately tuning the particle number statistics of the lowest-energy mode partially decouples the low- and high-energy sectors, allowing any low-energy single-particle wave function to define a background for sine-Gordon dynamics on curved spacetime and (2) macroscopic occupation of a quantum superposition of two states of the lowest two modes produces an analogue curved spacetime depending on two background flows, with respective weights continuously dependent on the corresponding weights of the superposed quantum states.

    Here, we explore the possibility of multi-site breather states in a nonlinear Klein–Gordon lattice to become nonlinearly unstable, even if they are found to be spectrally stable. The mechanism for this nonlinear instability is through the resonance with the wave continuum of a multiple of an internal mode eigenfrequency in the linearization of excited breather states. For the nonlinear instability, the internal mode must have its Krein signature opposite to that of the wave continuum. This mechanism is not only theoretically proposed, but also numerically corroborated through two concrete examples of the Klein–Gordon lattice with a soft (Morse) and amore » hard (Φ4) potential. Compared to the case of the nonlinear Schrödinger lattice, the Krein signature of the internal mode relative to that of the wave continuum may change depending on the period of the multi-site breather state.

    Ralph Robert Robbins, Jr., died on 2 December 2005, in Kyle, Texas. His wife, Maria Elena Robbins, his daughters Julia Robbins Kelso and Stephanie Juarez Balles, his son Matthew Juarez, and five grandchildren survive him. Bob was on the faculty at the University of Texas from 1968 until his retirement in 2003. Bob was born in Wichita, Kansas, on 2 September 1938, the only son of Mildred and Ralph Robert Robbins, Sr. Guided by his high school's policy to provide a practical education to children of working-class parents, Bob began high school with a heavy dose of vocational courses until the results of a test indicated his special talent in mathematics. He was awarded a full scholarship to Yale University, graduating magna cum laude in mathematics in 1960. He won the Warner Prize in Mathematics at Yale that year. He received his Ph.D. in 1966 with a dissertation entitled "The Triplet Spectrum of Neutral Helium in Expanding Nebulae" from the University of California at Berkeley. His interest in college teaching was ignited at this time through summer teaching positions at San Mateo California Junior College and the Ohio State University. Following a year at Texas as a McDonald Observatory Post-doctoral Fellow, Bob taught for a year in the physics department of the University of Houston before returning to the University of Texas at Austin as an Assistant Professor of Astronomy in 1968. He was promoted to Associate Professor in 1972. Bob's research in the early 1970s on theoretical studies of helium was of vital importance to astronomers for over three decades. These pioneering calculations became vital to observational astronomers in the mid-1990s as interest grew in the primordial helium produced by the Big Bang. Bob's interest and influence in education was international in scope. In the summers 1968-1970, he was a government consultant in Mathematics in East Pakistan (now Bangladesh). He consulted with the government that was preparing a master plan for technical

    2016-01-01

    Slower-than-light multi-front solutions of the Sine-Gordon in (1+2) dimensions, constructed through the Hirota algorithm, are mapped onto spatially localized structures, which emulate free, spatially extended, massive relativistic particles. A localized structure is an image of the junctions at which the fronts intersect. It propagates together with the multi-front solution at the velocity of the latter. The profile of the localized structure obeys the linear wave equation in (1+2) dimensions, to which a term that represents interaction with a slower-than-light, Sine-Gordon-multi-front solution has been added. This result can be also formulated in terms of a (1+2)-dimensional Lagrangian system, in which the Sine-Gordon and wave equations are coupled. Expanding the Euler-Lagrange equations in powers of the coupling constant, the zero-order part of the solution reproduces the (1+2)-dimensional Sine-Gordon fronts. The first-order part is the spatially localized structure. PACS: 02.30.Ik, 03.65.Pm, 05.45.Yv, 02.30.Ik. PMID:26930077

    The publishers of Physics in Medicine and Biology (PMB), IOP Publishing, in association with the journal owners, the Institute of Physics and Engineering in Medicine (IPEM), jointly award the Roberts prize for the best paper published in PMB during the previous year. The procedure for deciding the winner is a two-stage process. First, a shortlist of contenders is drawn up based on those papers that had the best referees' quality assessments, with a further quality check and endorsement by the Editorial Board. The papers on the shortlist are then reviewed by a specially convened IPEM committee consisting of members with fellow status. This committee reads the shortlisted papers and selects the winner. We have much pleasure in advising readers that the Roberts Prize for the best paper published in 2012 is awarded to Michel Defrise, Ahmadreza Rezaei and Johan Nuyts from the Vrije Universiteit Brussels and the Katholieke Universiteit Leuven, Belgium for their breakthrough paper that describes how the information needed for attenuation correction in PET imaging can be extracted, to within a constant, from time-of-flight emission data: Time-of-flight PET data determine the attenuation sinogram up to a constant 2012 Phys.

    One of the most structurally complex areas along the northeastern margin of the Oregon Cascades is in Tygh Valley. Crustal shortening produced folds and extensional tectonics resulted in rifting during the Miocene/Pliocene. Rhyolite, exposed in channel cuts and river canyon, records this transition, summarized in new, more detailed research. Tygh Valley, Oregon, is a synclinal basin bordered by the Tygh Ridge anticline to the north, Mutton Mountains to the south, and the Cascade Range (with Mt. Hood) to the west. The stratigraphy of the basin consists of epi- and volcaniclastic deposits mostly derived from the Cascades Range, in addition to ash flow tuffs and surficial basalt lava flows. Rhyolite lava flows are found at two dome complexes in the Tygh Valley area, Graveyard Butte and Gordon Butte. At Graveyard Butte, the White River has cut a winding canyon 140 meters deep, exposing at its base, a 40-meter thick outcrop of flow-banded rhyolite (73 wt.% SiO2) that laterally extends along the canyon walls for about 1 km. Stratigraphically above the flow-banded rhyolites are locally-erupted Fe-rich andesites (lava flows, agglutinate and other pyroclastic rocks as well as clastic debris), a rhyolitic ash-flow tuff (74 wt.% SiO2) and the 2.7 My basalt lava flows of Juniper Flat. At Gordon Butte, compositionally similar rhyolite lavas are exposed in channel cuts but flows are less constrained on ridge tops due to heavy vegetation. Ongoing age dating experiments will likely reveal a late Miocene/Pliocene age for these rhyolite lava flows. The rhyolite lavas flows at both buttes are chemically nearly indistinguishable but contrast with the stratigraphically younger rhyolitic ash-flow tuff at Graveyard Butte. Rhyolite lavas are richer in Nb and Zr than the younger rhyolitic tuff (Nb 30-40 versus 13 ppm; Zr 490 versus 240 ppm) and share characteristics with much older (~30 Ma) rhyolites of the Western Cascades and John Day Formation of central and eastern Oregon as well as

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

    NASA Astrophysics Data System (ADS)

    Gérard, Christian; Oulghazi, Omar; Wrochna, Michał

    2017-03-01

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

  3. Klein-Gordon equation and reflection of Alfven waves in nonuniform media

    NASA Technical Reports Server (NTRS)

    Musielak, Z. E.; Fontenla, J. M.; Moore, R. L.

    1992-01-01

    A new analytical approach is presented for assessing the reflection of linear Alfven waves in smoothly nonuniform media. The general one-dimensional case in Cartesian coordinates is treated. It is shown that the wave equations, upon transformation into the form of the Klein-Gordon equation, display a local critical frequency for reflection. At any location in the medium, reflection becomes strong as the wave frequency descends past this characteristic frequency set by the local nonuniformity of the medium. This critical frequecy is given by the transformation as an explicit function of the Alfven velocity and its first and second derivatives, and hence as an explicit spatial function. The transformation thus directly yields, without solution of the wave equations, the location in the medium at which an Alfven wave of any given frequency becomes strongly reflected and has its propagation practically cut off.

  4. Phase transition from the symmetry breaking of charged Klein-Gordon fields

    NASA Astrophysics Data System (ADS)

    Matos, T.; Castellanos, E.

    2014-01-01

    We analyze the phase transition associated with the U(1) symmetry breaking of the complex Klein-Gordon (KG) equation with a Mexican-hat scalar field potential up to one loop in perturbations immersed in a thermal bath. We show that the KG equation reduces to a Gross-Pitaevskii like-equation (GP), which also contains the entire information of the phase transition. Indeed, the thermal bath contributions, together with the corresponding U(1) local symmetry, allow us to interpret the resulting GP equation as a charged and finite temperature version of the system. Finally, we obtain the hydrodynamics and consequently, the corresponding thermodynamics, and show that breakdown of the U(1) local symmetry of the KG field into the new version of the GP equation corresponds, under certain circumstances, to a phase transition of the gas into a condensate, superfluid, and/or superconductor.

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

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

    2007-08-15

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

    2009-03-16

    Gibbs ensemble Monte Carlo simulations were carried out to investigate the properties of a frozen-electron-density (or Kim-Gordon, KG) model of water along the vapor-liquid coexistence curve. Because of its theoretical basis, such a KG model provides for seamless coupling to Kohn-Sham density functional theory for use in mixed quantum mechanics/molecular mechanics (QM/MM) implementations. The Gibbs ensemble simulations indicate rather limited transferability of such a simple KG model to other state points. Specifically, a KG model that was parameterized by Barker and Sprik to the properties of liquid water at 300 K, yields saturated vapor pressures and a critical temperature that are significantly under- and over-estimated, respectively.

  8. On the Klein-Gordon equation using the dispersion relation of Doubly Special Relativity

    NASA Astrophysics Data System (ADS)

    Felipe, Yese J.

    2017-01-01

    The theory of Doubly Special Relativity or Deformed Special Relativity (DSR), proposes that there is a maximum energy scale and a minimum length scale that is invariant for all observers. These maximum energy and minimum length correspond to the Planck energy and the Planck length, respectively. As a consequence, the dispersion relation is modified to be E2 =p2c2 +m2c4 + λE3 + ... Previous work has been done to express Quantum Mechanics using the dispersion relation of DSR. Solutions of the free particle, the harmonic oscillator, and the Hydrogen atom have been obtained from the DSR Schrodinger equation. We explore how the DSR Klein-Gordon equation can be consistently approximated in the non-relativistic limit in order to derive the DSR Schrodinger equation.

    We incorporate a massless scalar field into a three-dimensional code for the characteristic evolution of the gravitational field. The extended three-dimensional code for the Einstein-Klein-Gordon system is calibrated to be second-order convergent. It provides an accurate calculation of the gravitational and scalar radiation at infinity. As an application, we simulate the fully nonlinear evolution of an asymmetric scalar pulse of ingoing radiation propagating toward an interior Schwarzschild black hole and compute the backscattered scalar and gravitational outgoing radiation patterns. The amplitudes of the scalar and gravitational outgoing radiation modes exhibit the predicted power law scaling with respect to the amplitude of the initial data. For the scattering of an axisymmetric scalar field, the final ring down matches the complex frequency calculated perturbatively for the l=2 quasinormal mode.

    Neutral excitations present in the repulsive regime (1/2 < β2/8π < 1) of the sine- Gordon/massive-Thirring model and its study of the massless limit by the thermodynamic Bethe ansatz is revisited. At β2/8π = 1 - 1/(p + 1) the solitons become infinitely heavy, forcing truncation to the neutral excitations alone. The central charge in this limit is calculated to be c = 1 - 6/p(p + 1); the mass and S-matrices of the truncated theories are identified as those of the minimal conformal theory Mp perturbed by the ϕ(1,3) operator.

    2010-10-01

    Based on a transformed Painlevé property and the variable separated ODE method, a function transformation method is proposed to search for exact solutions of some partial differential equations (PDEs) with hyperbolic or exponential functions. This approach provides a more systematical and convenient handling of the solution process of this kind of nonlinear equations. Its key point is to eradicate the hyperbolic or exponential terms by a transformed Painlevé property and reduce the given PDEs to a variable-coefficient ordinary differential equations, then we seek for solutions to the resulting equations by some methods. As an application, exact solutions for the combined sinh-cosh-Gordon equation are formally derived.

    The elastic scattering data for incident pion energies of 130, 163.3, 180, and 230 MeV on 40Ca have been analyzed using the full Klein-Gordon equation (KGE), as opposed to its approximate form which renders it to the format of a Schrödinger equation with an energy-dependent potential (RSE). Calculated angular distributions, using KGE and RSE, for all four cases are nearly the same up to about 70° but differ significantly at larger angles. To fit the large-angle data of 163.3 MeV, the nature of the old potential determined by using RSE needs to be revised. The new potentials in four cases are presented and they are compatible with those determined from the inverse scattering theory at a fixed energy in the surface region.

    We evaluate the dispersion relation for massless fermions, described by the Dirac equation, and for zero-spin bosons, described by the Klein-Gordon equation, moving in two dimensions and in the presence of a one-dimensional periodic potential. For massless fermions, the dispersion relation shows a zero gap for carriers with zero momentum in the direction parallel to the barriers in agreement with the well-known “Klein paradox.” Numerical results for the energy spectrum and the density of states are presented. Those for fermions are appropriate to graphene in which carriers behave relativistically with the “light speed” replaced by the Fermi velocity. In addition, we evaluate the transmission through a finite number of barriers for fermions and zero-spin bosons and relate it with that through a superlattice.

    The generalized nonlinear Klien-Gordon equation plays an important role in quantum mechanics. In this paper, a new three-time level implicit approach based on cubic trigonometric B-spline is presented for the approximate solution of this equation with Dirichlet boundary conditions. The usual finite difference approach is used to discretize the time derivative while cubic trigonometric B-spline is applied as an interpolating function in the space dimension. Several examples are discussed to exhibit the feasibility and capability of the approach. The absolute errors and L∞ error norms are also computed at different times to assess the performance of the proposed approach and the results were found to be in good agreement with known solutions and with existing schemes in literature.

  19. Reculturing and particularizing climate discourses: weather, identity, and the work of Gordon Manley.

    PubMed

    Endfield, Georgina

    2011-01-01

    During the last three decades, popular discourses of climate have been replaced by a global and scientific metanarrative focusing on climate change and global warming. Recent climate scholarship has thus highlighted the need for a reexamination of the idea of climate and its culturally and spatially variable dimensions, though anxieties over the reemergence of climatic determinism in a number of high-profile publications have compounded a reluctance to engage in scholarship exploring the influence of climate on society. This article focuses on the work of British meteorologist and geographer Gordon Manley, whose publications, particularly those produced for popular audiences in the second half of the twentieth century, focus on the relationships between climate, place, and identity in postwar Britain. I argue that his approach may have renewed significance given recent efforts to reparticularize and reculture climate change discourses.

    2010-05-01

    With regard to the thermalization problem in isolated quantum systems, we investigate the dynamics following a quantum quench of the sine-Gordon model (sGM) in the Luther-Emery and the semiclassical limits. We consider the quench from the gapped to the gapless phase, as well as the reverse one. By obtaining analytic expressions for the one- and two-point correlation functions of the order parameter operator at zero-temperature, the manifestations of integrability in the absence of thermalization in the sGM are studied. It is shown that correlations in the long-time regime after the quench are well described by a generalized Gibbs ensemble. We also consider the case where the system is initially in contact with a reservoir at finite temperature. The possible relevance of our results to current and future experiments with ultracold atomic systems is also considered.

    In 2008 the Gordon Research Conference on Multiphoton Processes is held for the 14th time. The meeting continues to evolve as it embraces both the rapid technological and intellectual growth in the field as well as the multi-disciplinary expertise of the participants. This time the sessions will focus on: (1) Attosecond Science; (2) Free-electron laser experiments and theory; (3) Ultrafast dynamics of molecules; (4) Laser control of molecules; (5) Ultrafast imaging; (6) Super-high intensity and x-rays; (7) Strong field processes in molecules; and (8) Control atoms with light and vice versa. The scientific program will blur traditional disciplinary boundaries as the presenters and discussion leaders involve chemists, physicists, and optical engineers, representing both experiment and theory. The broad range of expertise and different perspectives of attendees should provide a stimulating and unique environment for solving problems and developing new ideas in this rapidly evolving field.

    Roberts syndrome is a rare autosomal recessive genetic disorder (MIM 268300). It is characterized by pre and postnatal growth retardation, severe shortening of limbs with radial defects, oligodactyly and characteristic facial features. The present study reports 4 new cases of Roberts syndrome from 3 families presenting variable phenotypes. Patients were thoroughly investigated clinically and cytogenetically. By reviewing literature, we compared our cases to those previously reported. The rating severity system proposed by Van den Berg and Francke (30) was applied to correlate the phenotypic and cytogenetics changes. We observed more severe reduction defects in the upper limbs than in the lower limbs. While the main reduction defects in the upper limbs involved the thumb and radius ranging to phocomelia, absent or severely hypoplastic fibula was the main lower limb involvement. We emphasize this finding in the present investigation. Heterochromatin repulsion of chromosomes derived from Roberts syndrome patients is a characteristic cytogenetic abnormality. It was a constant finding in our studied patients demonstrated by DABI stain which supports the possibility that mutations in Roberts syndrome lie in centromere related proteins which may also play a role in body patterning. This was proved recently by Vega et al. (31). Application of the clinical rating score and its correlation with cytogenetic changes showed negative results. Cytogenetic studies in normal obligatory heterozygotes parents showed no changes. Phenotypic variability within the same family as well as between different families was observed. The ascertainment of 4 cases with Roberts syndrome from 3 Egyptian consanguineous families during one year in our department may indicate a high frequency of the Roberts syndrome allele among Egyptians. This confirms the need for molecular studies for early and accurate prenatal diagnosis to prevent such dramatic malformation syndrome.

    The Gordon Research Conference on 'Molecular and Ionic Clusters' focuses on clusters, which are the initial molecular species found in gases when condensation begins to occur. Condensation can take place solely from molecules interacting with each other, mostly at low temperatures, or when molecules condense around charged particles (electrons, protons, metal cations, molecular ions), producing ion molecule clusters. These clusters provide models for solvation, allow a pristine look at geometric as well as electronic structures of molecular complexes or matter in general, their interaction with radiation, their reactivity, their thermodynamic properties and, in particular, the related dynamics. This conference focuses on new ways to make clusters composed of different kinds of molecules, new experimental techniques to investigate the properties of the clusters and new theoretical methods with which to calculate the structures, dynamical motions and energetics of the clusters. Some of the main experimental methods employed include molecular beams, mass spectrometry, laser spectroscopy (from infrared to XUV; in the frequency as well as the time domain) and photoelectron spectroscopy. Techniques include laser absorption spectroscopy, laser induced fluorescence, resonance enhanced photoionization, mass-selected photodissociation, photofragment imaging, ZEKE photoelectron spectroscopy, etc. From the theoretical side, this conference highlights work on potential surfaces and measurable properties of the clusters. The close ties between experiment, theory and computation have been a hallmark of the Gordon Research Conference on Molecular and Ionic Clusters. In the 2012 meeting, we plan to have sessions that will focus on topics including: (1) The use of cluster studies to probe fundamental phenomena; (2) Finite size effects on structure and thermodynamics; (3) Intermolecular forces and cooperative effects; (4) Molecular clusters as models for solvation; and (5) Studies of

    The Craig-Gordon model (C-G model) [H. Craig, L.I. Gordon. Deuterium and oxygen 18 variations in the ocean and the marine atmosphere. In Stable Isotopes in Oceanographic Studies and Paleotemperatures, E. Tongiorgi (Ed.), pp. 9-130, Laboratorio di Geologia Nucleare, Pisa (1965).] has been synonymous with the isotope effects associated with the evaporation of water from surface waters, soils, and vegetations, which in turn constitutes a critical component of the global water cycle. On the occasion of the four decades of its successful applications to isotope geochemistry and hydrology, an attempt is made to: (a) examine its physical background within the framework of modern evaporation models, (b) evaluate our current knowledge of the environmental parameters of the C-G model, and (c) comment on a general strategy for the use of these parameters in field applications. Despite its simplistic representation of evaporation processes at the water-air interface, the C-G model appears to be adequate to provide the isotopic composition of the evaporation flux. This is largely due to its nature for representing isotopic compositions (a ratio of two fluxes of different isotopic water molecules) under the same environmental conditions. Among many environmental parameters that are included in the C-G model, accurate description and calculations are still problematic of the kinetic isotope effects that occur in a diffusion-dominated thin layer of air next to the water-air interface. In field applications, it is of importance to accurately evaluate several environmental parameters, particularly the relative humidity and isotopic compositions of the 'free-atmosphere', for a system under investigation over a given time-scale of interest (e.g., hourly to daily to seasonally). With a growing interest in the studies of water cycles of different spatial and temporal scales, including paleoclimate and water resource studies, the importance and utility of the C-G model is also likely to

    The U.S. Geological Survey, in cooperation with the U.S. Department of the Army at Fort Gordon, Georgia, deployed GORE1 adsorbent samplers along creeks and floodplains to rapidly assess potential contamination at abandoned facilities and in adjacent surface water. The samplers provide screening-level data to determine the presence or absence of volatile organic compounds, semi-volatile organic compounds, and polycyclic aromatic hydrocarbons and were deployed in saturated creek and floodplain sediments adjacent to four abandoned waste-disposal/warfare-training sites. Fuelrelated compounds, not solvents, are the most prevalent organic compounds detected along segments of McCoys Creek adjacent to the 19th Street landfill; South Prong Creek adjacent to the South Prong Creek waste-disposal area; an unnamed tributary to Butler Creek adjacent to the old hospital landfill; and the Brier Creek floodplain adjacent to the Patterson anti-tank range. All 37 samplers deployed in these assessments had detections of total petroleum hydrocarbons ranging from just above 3 (laboratory method detection level) to 344 micrograms per liter. Detections of octane that ranged from 1 to 7.6 micrograms per liter were common in all assessments, except for South Prong Creek. Calculated concentrations of benzene are at or just above the National Primary Drinking Water Standard maximum contaminant level for all samplers deployed in the floodplain at the Patterson anti-tank range. The highest calculated concentration of a specific fuel-related compound was for toluene collected at one sampling site on McCoys Creek adjacent to the 19th Street landfill, but the concentration was below the National Primary Drinking Water Standard. These results are being used by Fort Gordon environmental compliance personnel to decide if further assessments are needed at these abandoned waste-disposal/warfare-training sites

    Photosynthesis is the biological process that converts solar energy into chemical energy. Elucidation of the mechanisms of photosynthetic energy conversion at a molecular level is fundamentally important for understanding the biology of photosynthetic organisms, for optimizing biological solar fuels production, and for developing biologically inspired approaches to solar energy conversion. The 2011 Gordon Conference on Photosynthesis will present cutting-edge research focusing on the biochemical aspects of photosynthesis, including: (1) structure, assembly, and function of photosynthetic complexes; (2) the mechanism of water splitting by PSII; (3) light harvesting and quenching; (4) alternative electron transport pathways; (5) biosynthesis of pigments and cofactors; and (6) improvement of photosynthesis for bioenergy and food production. Reflecting the interdisciplinary nature of photosynthesis research, a diverse group of invited speakers will represent a variety of scientific approaches to investigate photosynthesis, such as biochemistry, molecular genetics, structural biology, systems biology, and spectroscopy. Highly interactive poster sessions provide opportunities for graduate students and postdocs to present their work and exchange ideas with leaders in the field. One of the highlights of the Conference is a session featuring short talks by junior investigators selected from the poster presentations. The collegial atmosphere of the Photosynthesis GRC, with programmed discussion sessions as well as informal gatherings in the afternoons and evenings, enables participants to brainstorm, exchange ideas, and forge new collaborations. For the second time, this Conference will be immediately preceded by a Gordon Research Seminar on Photosynthesis (June 11-12, 2011, at the same location), with a focus on 'Photosynthesis, Bioenergy, and the Environment.' The GRS provides an additional opportunity for graduate students and postdocs to present their research, and it

    We compute multi-instanton amplitudes in the sine-Gordon quantum mechanics (periodic cosine potential) by integrating out quasi-moduli parameters corresponding to separations of instantons and anti-instantons. We propose an extension of Bogomolnyi-Zinn-Justin prescription for multi-instanton configurations and an appropriate subtraction scheme. We obtain the multi-instanton contributions to the energy eigenvalue of the lowest band at the zeroth order of the coupling constant. For the configurations with only instantons (anti-instantons), we obtain unambiguous results. For those with both instantons and anti-instantons, we obtain results with imaginary parts, which depend on the path of analytic continuation. We show that the imaginary parts of the multi-instanton amplitudes precisely cancel the imaginary parts of the Borel resummation of the perturbation series, and verify that our results completely agree with those based on the uniform-WKB calculations, thus confirming the resurgence structure: divergent perturbation series combined with the nonperturbative multi-instanton contributions conspire to give unambiguous results. We also study the neutral bion contributions in the {C}{P}^{N-1} model on {{R}}^1× {S}^1 with a small circumference, taking account of the relative phase moduli between the fractional instanton and anti-instanton. We find that the sign of the interaction potential depends on the relative phase moduli, and that both the real and imaginary parts resulting from quasi-moduli integral of the neutral bion get quantitative corrections compared to the sine-Gordon quantum mechanics.

    Robert H. Pudenz was a renowned neurosurgeon in North America in the 20th century, famous for his contributions in the evolution of the shunt valve and ventriculoatrial shunt surgery. With his innovative idea and help from Heyer, in 1955, he demonstrated that a venous catheter worked best when in the right atrium and that the slit valve should be located at the most distal portion of the shunt system to prevent retrograde filling and thrombosis. He also contributed to various experimental studies on the brain, especially the electrical response of different neural structures. This historical vignette focuses on the work of Robert Pudenz and the evolution of the ventriculoatrial shunt.

    Five nodules of eclogite, one nodule of garnet peridotite, and one sample of kimberlite from the Roberts Victor Mine in the Orange Free State were analyzed for concentrations of U, Th, Pb, Rb, and Sr, and also isotopic compositions of Pb and Sr. Results are presented and analyzed. They indicate that the Roberts Victor eclogites have been contaminated by lead from the host rock of kimberlite. This finding suggests that stepwise extraction of lead may be a means of obtaining the isotopic composition of the primary lead in kimberlitic eclogites.

    Major Robert M. White is seen here next to the X-15 aircraft after a research flight. White was one of the initial pilots selected for the X-15 program, representing the Air Force in the joint program with NASA, the Navy, and North American Aviation. Between 13 April 1960 and 14 December 1962, he made 16 flights in the rocket-powered aircraft. He was the first pilot to fly to Mach 4, 5, and 6 (respectively 4, 5, and 6 times the speed of sound). He also flew to the altitude of 314,750 feet on 17 July 1962, setting a world altitude record. This was 59.6 miles, significantly higher than the 50 miles the Air Force accepted as the beginning of space, qualifying White for astronaut wings. The X-15 was a rocket-powered aircraft. The original three aircraft were about 50 ft long with a wingspan of 22 ft. The modified #2 aircraft (X-15A-2 was longer.) They were a missile-shaped vehicles with unusual wedge-shaped vertical tails, thin stubby wings, and unique side fairings that extended along the side of the fuselage. The X-15 weighed about 14,000 lb empty and approximately 34,000 lb at launch. The XLR-99 rocket engine, manufactured by Thiokol Chemical Corp., was pilot controlled and was rated at 57,000 lb of thrust, although there are indications that it actually achieved up to 60,000 lb. North American Aviation built three X-15 aircraft for the program. The X-15 research aircraft was developed to provide in-flight information and data on aerodynamics, structures, flight controls, and the physiological aspects of high-speed, high-altitude flight. A follow-on program used the aircraft as testbeds to carry various scientific experiments beyond the Earth's atmosphere on a repeated basis. For flight in the dense air of the usable atmosphere, the X-15 used conventional aerodynamic controls such as rudder surfaces on the vertical stabilizers to control yaw and movable horizontal stabilizers to control pitch when moving in synchronization or roll when moved differentially.

    The relativistic quantum dynamics of an electrically charged particle subject to the Klein–Gordon oscillator and the Coulomb potential is investigated. By searching for relativistic bound states, a particular quantum effect can be observed: a dependence of the angular frequency of the Klein–Gordon oscillator on the quantum numbers of the system. The meaning of this behaviour of the angular frequency is that only some specific values of the angular frequency of the Klein–Gordon oscillator are permitted in order to obtain bound state solutions. As an example, we obtain both the angular frequency and the energy level associated with the ground state of the relativistic system. Further, we analyse the behaviour of a relativistic position-dependent mass particle subject to the Klein–Gordon oscillator and the Coulomb potential.

    Camp Roberts is a California Army National Guard Training Site located in central California. The San Joaquin kit fox, an endangered subspecies of kit fox, has been known to occur at Camp Roberts since 1960. The population of foxes began to increase in the early 1970's when use of rodenticides decreased. In 1987 the California Army National Guard contracted EG G Energy Measurements to conduct a 3-year study to assess the effects of Camp Roberts activities on the kit fox population. The major objective of the Camp Roberts Environmental Studies Program is to prepare a comprehensive Biological Assessment of the effects of all NGB-authorized activities (includes military training, anticipated construction projects, repair and maintenance activities, and all NGB-authorized non-military activities such as hunting and fishing programs, grazing leases, etc.) on San Joaquin kit fox. The program also provides NGB with the scientific expertise necessary to insure compliance with the Endangered Species Act. The specific objective of this report is to summarize progress and results of the Environmental Studies Program made during Fiscal Years 1989 and 1990 (FY89/90). 32 refs., 9 figs., 14 tabs.

    SciTech Connect

    Ginger, E.P. )

    1992-04-01

    The Permian San Andres reservoir at Roberts unit produces from approximately 250 ft of anhydritic dolostones. The reservoir interval, which is more than 500 ft below the top of the San Andres Formation, consists of fossiliferous and pelletal/peloidal dolowackestones and dolopackstones. They were deposited in a shallow-marine environment with local shoaling conditions. Toward the top of the reservoir, intertidal and supratidal deposits interfinger with the subtidal units and form the lateral and overlying seals. A sponge-bryozoan bank lithofacies is recognized within the subtidal deposits at Roberts unit. The banks consist of dolomitized mud-rich boundstones dominated by bryozoans, sponges, and crinoids. Interbedded fossiliferous dolowackestones, dolopackstones, and dolograinstones are common. The restricted nature of the San Andres in the western part of Roberts unit (i.e., shoreward of the banks) indicates that the banks baffled wave energy and inhibited current circulation on the platform, resulting in a mud-dominated, restricted lagoonal facies with very low faunal diversity. The sponge-bryozoan banks occur within a narrow belt across the central part of Roberts unit and continue into the adjacent Willard unit. Their distribution has a distinct northeast-soutwest trend that parallels the subjacent Abo shelf margin reef trend, suggesting that the Abo reef trend influenced subsequent bank development.

    Vieira, H.S.; Bezerra, V.B.; Muniz, C.R.

    2014-11-15

    This work considers the influence of the gravitational field produced by a charged and rotating black hole (Kerr–Newman spacetime) on a charged massive scalar field. We obtain exact solutions of both angular and radial parts of the Klein–Gordon equation in this spacetime, which are given in terms of the confluent Heun functions. From the radial solution, we obtain the exact wave solutions near the exterior horizon of the black hole, and discuss the Hawking radiation of charged massive scalar particles. - Highlights: • The covariant Klein–Gordon equation for a charged massive scalar field in the Kerr–Newman black hole is solved. • Both angular and radial parts are transformed to a Heun-type equation. • The resulting Hawking radiation spectrum of scalar particles has a thermal character.

    The Jacksonburg-Stringtown oil field contained an estimated 88,500,000 barrels of oil in place, of which approximately 20,000,000 barrels were produced during primary recovery operations. A gas injection project, initiated in 1934, and a pilot waterflood, begun in 1981, yielded additional production from limited portions of the field. The pilot was successful enough to warrant development of a full-scale waterflood in 1990, involving approximately 8,900 acres in three units, with a target of 1,500 barrels of oil per acre recovery. Historical patterns of drilling and development within the field suggests that the Gordon reservoir is heterogeneous, and that detailed reservoir characterization is necessary for understanding well performance and addressing problems observed by the operators. The purpose of this work is to establish relationships among permeability, geophysical and other data by integrating geologic, geophysical and engineering data into an interdisciplinary quantification of reservoir heterogeneity as it relates to production. Conventional stratigraphic correlation and core description shows that the Gordon sandstone is composed of three parasequences, formed along the Late Devonian shoreline of the Appalachian Basin. The parasequences comprise five lithofacies, of which one includes reservoir sandstones. Pay sandstones were found to have permeabilities in core ranging from 10 to 200 mD, whereas non-pay sandstones have permeabilities ranging from below the level of instrumental detection to 5 mD; Conglomeratic zones could take on the permeability characteristics of enclosing materials, or could exhibit extremely low values in pay sandstone and high values in non-pay or low permeability pay sandstone. Four electrofacies based on a linear combination of density and scaled gamma ray best matched correlations made independently based on visual comparison of geophysical logs. Electrofacies 4 with relatively high permeability (mean value > 45 mD) was

By using an Lp -Lq estimate for eigenfunctions of the harmonic oscillator and by carefully analysis on the nonlinearity, we improve the result obtained by the author before.

  18. Geomorphology and groundwater origin of amphitheater-shaped gullies at Fort Gordon, Georgia, 2010-2012

    USGS Publications Warehouse

    Landmeyer, James E.; Wellborn, John B.

    2013-01-01

    Seven amphitheater-shaped gullies at valley heads in the northern part of Fort Gordon, Georgia, were identified by personnel from Fort Gordon and the U.S. Geological Survey during a field investigation of environmental contamination near the cantonment area between 2008 and 2010. Between 2010 and 2012, the amphitheater-shaped gullies were photographed, topographic features were surveyed using a global positioning system device, and the extent of erosion was estimated using Light Detection and Ranging imagery. The seven gullies are distributed across a broad area (and most likely are not the only examples) and have a similar geomorphology that includes (1) an amphitheater (semicircular) shaped escarpment at the upgradient end on a plateau of Upper Eocene sands of no readily discernible elevated catchment area or natural surface-water drainage; (2) a narrow, trench-shaped, flat-bottomed incisement of low-permeability marl at the downgradient end; and (3) steep-sided valley walls, some formed by landslides. Surface-water runoff is an unlikely cause for the amphitheater-shaped gullies, because each valley has a relatively small drainage area of sandy terrain even at those gullies that have recently received discharge from stormwater drains. Also, presumed high rates of runoff and gully formation associated with historic land uses, such as clearcutting, cotton production, and silviculture, would have occurred no later than when the fort was established in the early 1900s. The lack of an elevated catchment area at the headward scarps, the amphitheater shape, and presence of low permeability marl at the base of each feature provides the most convincing lines of evidence for headward erosion by groundwater sapping. The absence of current (2013) seeps and springs at most of the amphitheater-shaped gullies indicates that the gullies may have been formed previously by groundwater sapping under conditions of higher and (or) sustained precipitation amounts, local water

    The 2009 Gordon Conference on Microbial Population Biology will cover a diverse range of cutting edge issues in the microbial sciences and beyond. Firmly founded in evolutionary biology and with a strongly integrative approach, past Conferences have covered a range of topics from the dynamics and genetics of adaptation to the evolution of mutation rate, community ecology, evolutionary genomics, altruism, and epidemiology. The 2009 Conference is no exception, and will include sessions on the evolution of infectious diseases, social evolution, the evolution of symbioses, experimental evolution, adaptive landscapes, community dynamics, and the evolution of protein structure and function. While genomic approaches continue to make inroads, broadening our knowledge and encompassing new questions, the conference will also emphasize the use of experimental approaches to test hypotheses decisively. As in the past, this Conference provides young scientists and graduate students opportunities to present their work in poster format and exchange ideas with leading investigators from a broad spectrum of disciplines. This meeting is never dull: some of the most significant and contentious issues in biology have been thrashed out here. The 2009 meeting will be no exception.
