    Aspirin exerts antiplatelet effects through irreversible inhibition of cyclooxygenase-1, whereas its anticancer effects may be due to inhibition of cyclooxygenase-2 and other pathways. In 2009, the U.S. Preventive Services Task Force endorsed aspirin for primary prevention of cardiovascular disease. However, aspirin's role in cancer prevention is still emerging, and no groups currently recommend its use for this purpose. To help physicians balance the benefits and harms of aspirin in primary disease prevention, the Task Force issued a guideline titled, "Aspirin Use for the Primary Prevention of Cardiovascular Disease and Colorectal Cancer" in 2016. In the evidence review conducted for the guideline, cardiovascular disease mortality and colorectal cancer mortality were significantly reduced among persons taking aspirin. However, there was no difference in nonfatal stroke, cardiovascular disease mortality, or all-cause mortality, nor in total cancer mortality, among those taking aspirin. Aspirin users were found to be at increased risk for major gastrointestinal bleeding. In this Beyond the Guidelines, the guideline is reviewed and 2 experts discuss how they would apply it to a 57-year-old man considering starting aspirin for primary prevention. Our experts review the data on which the guideline is based, discuss how they would balance the benefits and harms of aspirin therapy, and explain how they would incorporate shared decision making into clinical practice.

    In 2015, the American Geriatrics Society released recommendations for prevention and management of postoperative delirium, based on a systematic literature review and evaluation of nonpharmacologic and pharmacologic approaches by an expert panel. The guidelines recommend an interdisciplinary focus on nonpharmacologic measures (reorientation, medication management, early mobility, nutrition, and gastointestinal motility) for prevention and consideration of this strategy for acute management. They also recommend optimizing nonopioid medication as a means to manage pain and avoiding benzodiazepines other than to treat substance withdrawal. The authors concluded that evidence to recommend antipsychotics for prevention of delirium is insufficient but that these drugs may be considered for short-term treatment in the setting of imminent harm to the patient or caregivers or severe distress due to agitation. Patients should be given the lowest possible dose for the shortest duration when other nonpharmacologic measures have failed. In this Beyond the Guidelines, a psychiatrist and a geriatrician debate whether Mr. W, a 79-year-old man at high risk for postoperative delirium, should receive prophylactic antipsychotics with his next surgery. They review risk factors, appropriate evaluation, and potential benefits and harms of the various medications often used in this setting.

    Full Text Available La cerámica Khirbet Kerak, descubierta en el sudoeste del Mar de Galilea en 1930 por W. F. Albright, ha sido desde entonces motivo de muchas controversias. Las razones de las discusiones en torno a este estilo radican  en su carácter aparentemente intrusivo en Palestina, entre el 2800-2400  a.C., puesto que esta cerámica es típica en la Cultura Transcaucásica Temprana o Cultura Kura-Araxes y en Siria Septentrional, durante el Bronce Antiguo, siendo especialmente abundante en la etapa final de este período. Sin embargo los estudios realizados en Beth Shan (Chazan y McGovern, ver n. 17, muestran que los materiales Khirbet Kerak fueron de producción local lo que parece descartar su carácter intrusivo. Por tanto, desde nuestro punto de vista, el “fenómeno Khirbet Kerak” constituye así un hito de singular importancia en la conformación de las tradiciones culturales de Canaan a partir de un sustrato etnocultural común hurrita, en un eje de interacción cultural norte a sur desde la región del Lago Van, que habrá de proyectarse de distintas formas en la macrorregión alcanzando hasta los antiguos hebreos, en cuanto cananeos, como se reflejan en instituciones del derecho privado presentes en las narraciones del Génesis.Palabras clave: Canaán - Bronce Antiguo - Beth Yerah - Khirbet Kerak - Hurritas- Hebreos

    Israel's ambiguous posture gradually emerged, although Israel, according to all international accounts, continued to pursue the development of a nuclear weapon option. The evolution of Israeli policy on this issue constitutes the main focus of this paper. Beginning with a detailed account of the strategic and political context, the initial Israeli decisions to develop a nuclear infrastructure are examined. Next, Israel's decision to adopt an ambiguous stance, the various features of the current threshold posture and the reasons for Israel's restraint will respect to nuclear weapon development are explored. The role played by the nuclear dimension in the Arab-Israeli conflict and in the Middle east peace process constitutes a third area to be discussed. The paper then examines the intended and actual functions of Israel's threshold posture, before concluding with an analysis of some of the implications for arms control

    In the area of nuclear weapons and the development of the potential capability as a nuclear supplier, as in many other issues, Israel stands out as a highly unusual, and indeed unique, case. In contrast to most other states considered in this paper such as Argentina, Brazil, and South Korea, Israel does not have an active civil nuclear energy industry. Despite some meager efforts in this direction, Israel does not operate large civil nuclear power reactors, and no Israeli firms produce commercial nuclear fuel cycle components of significance. Thus, many of the commercial and political factors that contribute to the emergence of second-tier suppliers are not salient in the Israeli case. Israel's status as a potential second tier nuclear supplier is based on its own nuclear weapons program and capability. Israeli scientists and engineers have clearly developed the technical infrastructure and facilities to design, produce, test, and deploy nuclear weapons and appropriate delivery vehicles

  9. Topics in Bethe Ansatz

    Science.gov (United States)

    Wang, Chunguang

    Integrable quantum spin chains have close connections to integrable quantum field. theories, modern condensed matter physics, string and Yang-Mills theories. Bethe. ansatz is one of the most important approaches for solving quantum integrable spin. chains. At the heart of the algebraic structure of integrable quantum spin chains is. the quantum Yang-Baxter equation and the boundary Yang-Baxter equation. This. thesis focuses on four topics in Bethe ansatz. The Bethe equations for the isotropic periodic spin-1/2 Heisenberg chain with N. sites have solutions containing ±i/2 that are singular: both the corresponding energy and the algebraic Bethe ansatz vector are divergent. Such solutions must be carefully regularized. We consider a regularization involving a parameter that can be. determined using a generalization of the Bethe equations. These generalized Bethe. equations provide a practical way of determining which singular solutions correspond. to eigenvectors of the model. The Bethe equations for the periodic XXX and XXZ spin chains admit singular. solutions, for which the corresponding eigenvalues and eigenvectors are ill-defined. We use a twist regularization to derive conditions for such singular solutions to bephysical, in which case they correspond to genuine eigenvalues and eigenvectors of. the Hamiltonian. We analyze the ground state of the open spin-1/2 isotropic quantum spin chain. with a non-diagonal boundary term using a recently proposed Bethe ansatz solution. As the coefficient of the non-diagonal boundary term tends to zero, the Bethe roots. split evenly into two sets: those that remain finite, and those that become infinite. We. argue that the former satisfy conventional Bethe equations, while the latter satisfy a. generalization of the Richardson-Gaudin equations. We derive an expression for the. leading correction to the boundary energy in terms of the boundary parameters. We argue that the Hamiltonians for A(2) 2n open quantum spin chains

    Hans Bethe, who died on March 6 at the age of 98, was exemplary as a scientist; a citizen-advocate seeking to stem the arms race; and an individual of warmth, generosity, tenacity, and modest habits. Bethe made major contributions to several areas of physics during his academic career. He earned a Nobel Prize in 1967 for his research into how the sun generates its energy by converting hydrogen to helium using carbon as a nuclear catalyst. A few years later, he made central contributions to the secret US World War II nuclear-weapon development programs (the "Manhattan Project").

    Michel Gaudin's book La fonction d'onde de Bethe is a uniquely influential masterpiece on exactly solvable models of quantum mechanics and statistical physics. Available in English for the first time, this translation brings his classic work to a new generation of graduate students and researchers in physics. It presents a mixture of mathematics interspersed with powerful physical intuition, retaining the author's unmistakably honest tone. The book begins with the Heisenberg spin chain, starting from the coordinate Bethe Ansatz and culminating in a discussion of its thermodynamic properties. Delta-interacting bosons (the Lieb-Liniger model) are then explored, and extended to exactly solvable models associated to a reflection group. After discussing the continuum limit of spin chains, the book covers six- and eight-vertex models in extensive detail, from their lattice definition to their thermodynamics. Later chapters examine advanced topics such as multi-component delta-interacting systems, Gaudin magnets and...

    We describe an integrable model, related to the Gaudin magnet, and its relation to the matrix model of Brezin, Itzykson, Parisi and Zuber. Relation is based on Bethe ansatz for the integrable model and its interpretation using orthogonal polynomials and saddle point approximation. Lagre $N$ limit of the matrix model corresponds to the thermodynamic limit of the integrable system. In this limit (functional) Bethe ansatz is the same as the generating function for correlators of the matrix models.

  19. [Rationalization of Protestant nursing. A comparison of Deaconess Motherhouses in West Germany and the United States, 1945-1970].

    Kreutzer, Susanne

    2012-01-01

    Protestant Deaconess Motherhouses emerged as a German nursing organization in the nineteenth century to be later exported to many other countries including the United States. The motherhouse principle could not be simply transferred without being adapted to the situation prevailing in each of those countries. The essay investigates the conception and transformation of Protestant nursing by comparing a West German and American deaconess motherhouse each in their particular context. It shows that the deaconesses in the United States developed their own, more scientifically oriented understanding of nursing and were therefore more open to the rationalization of nursing than their West German counterpart.

  20. Nursing body and soul in the parish: Lutheran deaconess motherhouses in Germany and the United States.

    Science.gov (United States)

    Kreutzer, Susanne

    2010-01-01

    In Lutheran Germany, parish nursing traditionally constituted the deaconesses' principal work. As "Christian mothers of the parish" they were charged with a wide spectrum of tasks, including nursing, social service, and pastoral care. At the center of the Christian understanding of nursing was the idea of nursing body and soul as a unity. This article analyzes the conception and transformation of Protestant parish nursing in the nineteenth and twentieth centuries in Germany and the United States, which developed very differently. In West Germany, parish nursing proved surprisingly resistant to modernization even in the face of upheavals of the 1960s, and in some places this traditional model survived as late as the 1980s and 1990s. In the United States, by contrast, an understanding of nursing rooted in the division of labor between care for body and care for soul had come to prevail by the 1920s and '30s, pushing out the German model of the parish deaconess altogether.

    A generalization of the Bethe ansatz equations is studied, where a scalar two-particle S-matrix has several zeroes and poles in the complex plane, as opposed to the ordinary single pole/zero case. For the repulsive case (no complex roots), the main result is the enumeration of all distinct solutions to the Bethe equations in terms of the Fuss-Catalan numbers. Two new combinatorial interpretations of the Fuss-Catalan and related numbers are obtained. On the one hand, they count regular orbits of the permutation group in certain factor modules over {{Z}^M}, and on the other hand, they count integer points in certain M-dimensional polytopes.

    We expand the Bethe/Gauge dictionary between the XXX Heisenberg spin chain and 2d N = (2, 2) supersymmetric gauge theories to include aspects of the algebraic Bethe ansatz. We construct the wave functions of off-shell Bethe states as orbifold defects in the A-twisted supersymmetric gauge theory and study their correlation functions. We also present an alternative description of off-shell Bethe states as boundary conditions in an effective N = 4 supersymmetric quantum mechanics. Finally, we interpret spin chain R-matrices as correlation functions of Janus interfaces for mass parameters in the supersymmetric quantum mechanics.

    The Deaconess Hospital, Edinburgh, opened in 1894 and was the first establishment of its kind in the UK, maintained and wholly funded as it was by the Reformed Church. Through its 96-year lifetime it changed and evolved to time and circumstance. It was a school: for the training of nurses and deaconesses who took their practical skills all over the world. It was a sanctum: for the sick-poor before the NHS. It was a subsidiary: for the bigger hospitals of Edinburgh after amalgamation into the NHS. It was a specialised centre: as the Urology Department in Edinburgh and the Scottish Lithotripter centre. And now it is currently student accommodation. There is no single source to account for its history. Through the use of original material made available by the Lothian Health Services Archives - including Church of Scotland publications, patient records, a doctor's casebook and annual reports - we review its conception, purpose, development and running; its fate on joining the NHS, its identity in the latter years and finally its closure.

    Almost a century ago, string states—complex bound states of magnetic excitations—were predicted to exist in one-dimensional quantum magnets. However, despite many theoretical studies, the experimental realization and identification of string states in a condensed-matter system have yet to be achieved. Here we use high-resolution terahertz spectroscopy to resolve string states in the antiferromagnetic Heisenberg-Ising chain SrCo2V2O8 in strong longitudinal magnetic fields. In the field-induced quantum-critical regime, we identify strings and fractional magnetic excitations that are accurately described by the Bethe ansatz. Close to quantum criticality, the string excitations govern the quantum spin dynamics, whereas the fractional excitations, which are dominant at low energies, reflect the antiferromagnetic quantum fluctuations. Today, Bethe’s result is important not only in the field of quantum magnetism but also more broadly, including in the study of cold atoms and in string theory; hence, we anticipate that our work will shed light on the study of complex many-body systems in general.

  10. Bethe Ansatz and supersymmetric vacua

    2009-01-01

    Supersymmetric vacua of two dimensional N = 4 gauge theories with matter, softly broken by the twisted masses down to N = 2, are shown to be in one-to-one correspondence with the eigenstates of integrable spin chain Hamiltonians. Examples include: the Heisenberg SU(2)XXX spin chain which is mapped to the two dimensional U(N) theory with fundamental hypermultiplets, the XXZ spin chain which is mapped to the analogous three dimensional super-Yang-Mills theory compactified on a circle, the XYZ spin chain and eight-vertex model which are related to the four dimensional theory compactified on T 2 . A consequence of our correspondence is the isomorphism of the quantum cohomology ring of various quiver varieties, such as cotangent bundles to (partial) flag varieties and the ring of quantum integrals of motion of various spin chains. The correspondence extends to any spin group, representations, boundary conditions, and inhomogeneity, it includes Sinh-Gordon and non-linear Schroedinger models as well as the dynamical spin chains like Hubbard model. Compactifications of four dimensional N = 2 theories on a two-sphere lead to the instanton-corrected Bethe equations.

    2007-12-01

    One of the unquestioned giants of physics and astrophysics, Hans Bethe, died on 6 March 2005, at the venerable age of 98, in his home town of Ithaca, New York. Seven decades of contributing to research and a Nobel Prize for his work on stellar hydrogen burning make a listing of his honors superfluous (besides being impossible in this space). Bethe was born in Strassburg, in then German Alsass Lothringen, on 2 July 1906. His father, Albrecht Julius Bethe (1872-1954), taught physiology at the University, and his mother, Anna Kuhn (1876-1966), was a musician and writer. Both his grandfathers were physicians. He spent his youth in Strassburg, Kiel, and Frankfurt, and some time in sanatoria due to tuberculosis. Hans's first scientific paper, at age 18, was with his father and a colleague, on dialysis. His education and early career in Germany brought him into contact with many top stars in the quantum revolution. Starting in Frankfurt in chemistry, Bethe soon switched to physics, taught there by Walter Gerlach and Karl Meissner, among others. In 1926, he successfully applied to join Arnold Sommerfeld's group in Munich, where he met one of his later long-term collaborators, Rudolf Peierls. Bethe considered his entry into physics to have come at an ideal time, with the new ideas of wave mechanics being developed and discussed right there; it was certainly also at an ideal place. His doctoral thesis was on the theory of electron diffraction by crystals, following the experimental work by Clinton Davisson and Lester Germer and the work on X-ray diffraction by Max von Laue and Paul Ewald. The newly minted doctor went from there briefly to Frankfurt and then to Ewald in Stuttgart, where he felt at home academically and personally. In 1939, Bethe would marry Ewald's daughter Rose. Not much later, though, Sommerfeld recalled him to Munich, where Sommerfeld created a Privatdozent position for him. There he worked out the solution for a linear chain of coupled spins by what we

    2000-01-01

    We give a brief review on the use of Bethe Ansatz techniques to construct solutions of recursive functional equations which emerged in a bootstrap approach to the quantum Ernst system. The construction involves two particular limits of a rational Bethe Ansatz system with complex inhomogeneities. First, we pinch two insertions to the critical value. This links Bethe systems with different number of insertions and leads to the concept of sequential Bethe vectors. Second, we study the semiclassical limit of the system in which the scale parameter of the insertions tends to infinity. (author)

    We derive the thermodynamic Bethe ansatz equation for the situation in which the statistical interaction of a multi-particle system is governed by Haldane statistics. We formulate a macroscopical equivalence principle for such systems. Particular CDD ambiguities play a distinguished role in compensating the ambiguity in the exclusion statistics. We derive Y-systems related to generalized statistics. We discuss several fermionic, bosonic and anyonic versions of affine Toda field theories and Calogero-Sutherland type models in the context of generalized statistics. (orig.)

    2016-08-01

    We give a pedagogical introduction to the thermodynamic Bethe ansatz, a method that allows us to describe the thermodynamics of integrable models whose spectrum is found via the (asymptotic) Bethe ansatz. We set the stage by deriving the Fermi-Dirac distribution and associated free energy of free electrons, and then in a similar though technically more complicated fashion treat the thermodynamics of integrable models, focusing first on the one-dimensional Bose gas with delta function interaction as a clean pedagogical example, secondly the XXX spin chain as an elementary (lattice) model with prototypical complicating features in the form of bound states, and finally the {SU}(2) chiral Gross-Neveu model as a field theory example. Throughout this discussion we emphasize the central role of particle and hole densities, whose relations determine the model under consideration. We then discuss tricks that allow us to use the same methods to describe the exact spectra of integrable field theories on a circle, in particular the chiral Gross-Neveu model. We moreover discuss the simplification of TBA equations to Y systems, including the transition back to integral equations given sufficient analyticity data, in simple examples.

    The astronomical community lost one of its most buoyant and caring individuals when Beth Brown died, unexpectedly, at the age of 39 from a pulmonary embolism. Beth Brown was born in Roanoke, Virginia where she developed a deep interest in astronomy, science, and science fiction (Star Trek). After graduating as the valedictorian of William Fleming High School's Class of 1987, she attended Howard University, where she graduated summa cum laude in 1991 with a bachelor's degree in astrophysics. Following a year in the graduate physics program at Howard, she entered the graduate program in the Department of Astronomy at the University of Michigan, the first African-American woman in the program. She received her PhD in 1998, working with X-ray observations of elliptical galaxies from the Röntgen Satellite (ROSAT; Joel Bregman was her advisor). She compiled and analyzed the first large complete sample of such galaxies with ROSAT and her papers in this area made an impact in the field. Following her PhD, Beth Brown held a National Academy of Science & National Research Council Postdoctoral Research Fellowship at NASA's Goddard Space Flight Center. Subsequently, she became a civil servant at the National Space Science Data Center at GSFC, where she was involved in data archival activities as well as education and outreach, a continuing passion in her life. In 2006, Brown became an Astrophysics Fellow at GSFC, during which time she worked as a visiting Assistant Professor at Howard University, where she taught and worked with students and faculty to improve the teaching observatory. At the time of her death, she was eagerly looking forward to a new position at GSFC as the Assistant Director for Science Communications and Higher Education. Beth Brown was a joyous individual who loved to work with people, especially in educating them about our remarkable field. Her warmth and openness was a great aid in making accessible explanations of otherwise daunting astrophysical

    Changing the variables in the Bethe Ansatz Equations (BAE) for the XXZ six-vertex model we had obtained a coupled system of polynomial equations. This provided a direct link between the BAE deduced from the Algebraic Bethe Ansatz (ABA) and the BAE arising from the Coordinate Bethe Ansatz (CBA). For two magnon states this polynomial system could be decoupled and the solutions given in terms of the roots of some self-inversive polynomials. From theorems concerning the distribution of the roots of self-inversive polynomials we made a thorough analysis of the two magnon states, which allowed us to find the location and multiplicity of the Bethe roots in the complex plane, to discuss the completeness and singularities of Bethe's equations, the ill-founded string-hypothesis concerning the location of their roots, as well as to find an interesting connection between the BAE with Salem’s polynomials.

  4. Algebraic Bethe ansatz for the Izergin-Korepin R matrix

    International Nuclear Information System (INIS)

    Tarasov, V.O.

    1989-01-01

    The authors propose a generalization of the algebraic Bethe ansatz for the Izergin-Korepin R matrix - the simplest unstudied odd-dimensional solution of the Yang-Baxter equation - and they discuss some related questions. The first section of the paper is an introduction. In the second they indicate a way of generalizing the algebraic Bethe ansatz to the case of the Izergin-Korepin R matrix. The simplest monodromy matrices (L operators) for this R matrix are described in the third section. The fourth section is devoted to the proof of the proposed generalization of the algebraic Bethe ansatz

  5. Off-diagonal Bethe ansatz for exactly solvable models

    CERN Document Server

    Wang, Yupeng; Cao, Junpeng; Shi, Kangjie

    2015-01-01

    This book serves as an introduction of the off-diagonal Bethe Ansatz method, an analytic theory for the eigenvalue problem of quantum integrable models. It also presents some fundamental knowledge about quantum integrability and the algebraic Bethe Ansatz method. Based on the intrinsic properties of R-matrix and K-matrices, the book introduces a systematic method to construct operator identities of transfer matrix.  These identities allow one to establish the inhomogeneous T-Q relation formalism to obtain Bethe Ansatz equations and to retrieve corresponding eigenstates. Several longstanding models can thus be solved via this method since the lack of obvious reference states is made up. Both the exact results and the off-diagonal Bethe Ansatz method itself may have important applications in the fields of quantum field theory, low-dimensional condensed matter physics, statistical physics and cold atom systems.

    Partial Néel states are generalizations of the ordinary Néel (classical anti-ferromagnet) state that can have arbitrary integer spin. We study overlaps of these states with Bethe states. We first identify this overlap with a partial version of reflecting-boundary domain-wall partition function, and then derive various determinant representations for off-shell and on-shell Bethe states.

    Extended calculations of the deuteron's static properties, based on the numerical solution of the Bethe-Salpeter equation, are presented. A formalism is developed, which provides a comparative analysis of the covariant amplitudes in various representations and nonrelativistic wave functions. The magnetic and quadrupole moments of the deuteron are calculated in the Bethe-Salpeter formalism and the role of relativistic corrections is discussed. (orig.)

  9. The Bethe-Salpeter equation with fermions

    International Nuclear Information System (INIS)

    Efimov, G.V.

    2007-01-01

    The Bethe-Salpeter (BS) equation in the ladder approximation is studied within a fermion theory: two fermion fields (constituents) with mass m interacting via an exchange of a scalar field with mass μ. The BS equation can be written in the form of an integral equation in the configuration Euclidean x-space with the symmetric kernel K for which Tr K 2 = ∞ due to the singular character of the fermion propagator. This kernel is represented in the form K = K 0 + K I . The operator K 0 with Tr K 0 2 ∞ is of the 'fall at the center' potential type and describes a continuous spectrum only. Besides the presence of this operator leads to a restriction on the value of the coupling constant. The kernel K I with Tr K I 2 2 c 2 and the variational procedure of calculations of eigenvalues and eigenfunctions can be applied. The quantum pseudoscalar and scalar mesodynamics is considered. The binding energy of the state 1 + (deuteron) as a function of the coupling constant is calculated in the framework of the procedure formulated above. It is shown that this bound state is absent in the pseudoscalar mesodynamics and does exist in the scalar mesodynamics. A comparison with the non-relativistic Schroedinger picture is made. (author)

  10. Nuclear forces the making of the physicist Hans Bethe

    CERN Document Server

    Schweber, Silvan S

    2012-01-01

    On the fiftieth anniversary of Hiroshima, Nobel-winning physicist Hans Bethe called on his fellow scientists to stop working on weapons of mass destruction. What drove Bethe, the head of Theoretical Physics at Los Alamos during the Manhattan Project, to renounce the weaponry he had once worked so tirelessly to create? That is one of the questions answered by "Nuclear Forces", a riveting biography of Bethe's early life and development as both a scientist and a man of principle. As Silvan Schweber follows Bethe from his childhood in Germany, to laboratories in Italy and England, and on to Cornell University, he shows how these differing environments were reflected in the kind of physics Bethe produced. Many of the young quantum physicists in the 1930s, including Bethe, had Jewish roots, and Schweber considers how Liberal Judaism in Germany helps explain their remarkable contributions. A portrait emerges of a man whose strategy for staying on top of a deeply hierarchical field was to tackle only those problems h...

    Based on waveguide theory we investigate electronic transport properties of Bethe lattices with a mesoscopic ring threaded by a magnetic flux. The generalized eigen-function method (GEM) is used to calculate the transmission and reflection coefficients up to the fifth generation of Bethe lattices. The relationships among the transmission coefficient T, magnetic flux φ and wave vector kl are investigated in detail. The numerical results are shown by the three-dimensional plots and contour maps. Some resonant-transmission features and the symmetry of the transmission coefficient T to flux φ are observed and discussed.

We define the Bethe vectors which yield the strikingly simple expression for the off shell action of the transfer matrix, deriving the spectrum and the relevant Bethe equations. We explore further these results by obtaining the off shell action of the generating function of the Gaudin Hamiltonians on the corresponding Bethe vectors through the so-called quasi-classical limit. Moreover, this action is as simple as it could possibly be, yielding the spectrum and the Bethe equations of the Gaudin model.

  20. Euclidean to Minkowski Bethe-Salpeter amplitude and observables

    International Nuclear Information System (INIS)

    Carbonell, J.; Frederico, T.; Karmanov, V.A.

    2017-01-01

    We propose a method to reconstruct the Bethe-Salpeter amplitude in Minkowski space given the Euclidean Bethe-Salpeter amplitude - or alternatively the light-front wave function - as input. The method is based on the numerical inversion of the Nakanishi integral representation and computing the corresponding weight function. This inversion procedure is, in general, rather unstable, and we propose several ways to considerably reduce the instabilities. In terms of the Nakanishi weight function, one can easily compute the BS amplitude, the LF wave function and the electromagnetic form factor. The latter ones are very stable in spite of residual instabilities in the weight function. This procedure allows both, to continue the Euclidean BS solution in the Minkowski space and to obtain a BS amplitude from a LF wave function. (orig.)

  1. Glueball properties from the Bethe-Salpeter equation

    International Nuclear Information System (INIS)

    2012-01-01

    For over thirty years bound states of gluons are an outstanding problem of both theoretical and experimental physics. Being predicted by Quantum-Chromodynamics their experimental confirmation is one of the foremost goals of large experimental facilities currently under construction like FAIR in Darmstadt. This thesis presents a novel approach to the theoretical determination of physical properties of bound states of two gluons, called glueballs. It uses the consistent combination of Schwinger-Dyson equations for gluons and ghosts and appropriate Bethe-Salpeter equations describing their corresponding bound-states. A rigorous derivation of both sets of equations, starting from an 2PI effective action is given as well as a general determination of appropriate decompositions of Bethe-Salpeter amplitudes to a given set of quantum numbers of a glueball. As an application example bound state masses of glueballs in a simple truncation scheme are calculated. (orig.)

    The structure-dependent amplitude of the decay {pi}{yields}e{nu}{gamma} is evaluated in the framework of a Bethe-Salpeter description for the pion. We assume a general B-S wave function in the S-wave. Within this hypothesis, we show that the gauge invariance constrains the different contributions of the wave functions to the amplitude, resulting in the vanishing of the axial form factor. (orig.).

The decay constant and the form factor derived from this are in excellent agreement with the data. (orig.)

    We study within the GW and Bethe-Salpeter many-body perturbation theories the electronic and optical properties of small (H{sub 2}O){sub n} water clusters (n = 1-6). Comparison with high-level CCSD(T) Coupled-Cluster at the Single Double (Triple) levels and ADC(3) Green’s function third order algebraic diagrammatic construction calculations indicates that the standard non-self-consistent G{sub 0}W{sub 0}@PBE or G{sub 0}W{sub 0}@PBE0 approaches significantly underestimate the ionization energy by about 1.1 eV and 0.5 eV, respectively. Consequently, the related Bethe-Salpeter lowest optical excitations are found to be located much too low in energy when building transitions from a non-self-consistent G{sub 0}W{sub 0} description of the quasiparticle spectrum. Simple self-consistent schemes, with update of the eigenvalues only, are shown to provide a weak dependence on the Kohn-Sham starting point and a much better agreement with reference calculations. The present findings rationalize the theory to experiment possible discrepancies observed in previous G{sub 0}W{sub 0} and Bethe-Salpeter studies of bulk water. The increase of the optical gap with increasing cluster size is consistent with the evolution from gas to dense ice or water phases and results from an enhanced screening of the electron-hole interaction.

    Two site spin correlation function for an Ising model above Curie temperature has been calculated by generalising Bethe-Peierls approximation. The results derived by a graphical method due to Englert are essentially the same as those obtained earlier by Elliott and Marshall, and Oguchi and Ono. The earlier results were obtained by a direct generalisation of the cluster method of Bethe, while these results are derived by retaining that class of diagrams , which is exact on Bethe lattice.

    In this work we formulate the standard form of the solutions of the Heisenberg chain with periodic boundary conditions and show that these solutions can be transformed into the well-known Bethe-Hulthen solutions. The standard form is found by solving the secular problem, separated according to the irreducible representations of the translation group. The relevant parameters exp(ik j ) of the Bethe-Hulthen solutions are found from a set of linear equations with coefficients derived from the standard solutions. This correspondence between standard and Bethe-Hulthen solutions realizes the completeness of the Bethe-Hulthen method

    Full Text Available We extend basic properties of two dimensional integrable models within the Algebraic Bethe Ansatz approach to 2+1 dimensions and formulate the sufficient conditions for the commutativity of transfer matrices of different spectral parameters, in analogy with Yang–Baxter or tetrahedron equations. The basic ingredient of our models is the R-matrix, which describes the scattering of a pair of particles over another pair of particles, the quark-anti-quark (meson scattering on another quark-anti-quark state. We show that the Kitaev model belongs to this class of models and its R-matrix fulfills well-defined equations for integrability.

Propagator self-energy corrections from the Ward idendity and phenomenological strong vertex corrections are both included. The photon is coupled minimally to pions, kaons and nucleons with power multiplicative renormalization. With solutions in the framework of the Bethe-Salpeter equation we obtain a value 1.84 for the isovector moment and a value -0.02 for the isoscalar moment. (orig.)

Beginning with the studies of motion by Galileo and Newton through to the revolutionary theories of relativity and quantum mechanics in the 20th century, all important aspects of electricity, energy, magnetism, gravity and the structure of matter and atoms are explained and illustrated. The second edition similarly recounts the more recent application of these theories to nanoparticles, Bose-Einstein condensates, quantum entanglement and quantum computers. By

  19. Bethe ansatz equations for open spin chains from giant gravitons

    International Nuclear Information System (INIS)

    Nepomechie, Rafael I.

    2009-01-01

    We investigate the open spin chain describing the scalar sector of the Y = 0 giant graviton brane at weak coupling. We provide a direct proof of integrability in the SU(2) and SU(3) sectors by constructing the transfer matrices. We determine the eigenvalues of these transfer matrices in terms of roots of the corresponding Bethe ansatz equations (BAEs). Based on these results, we propose BAEs for the full SO(6) sector. We find that, in the weak-coupling limit, the recently-proposed all-loop BAEs essentially agree with those proposed in the present work.

  20. Covariant solutions of the Bethe-Salpeter equation

    There is a need for covariant solutions of bound state equations in order to construct realistic QCD based models of mesons and baryons. Furthermore, we ideally need to know the structure of these bound states in all kinematical regimes, which makes a direct solution in Minkowski space (without any 3-dimensional reductions) desirable. The Bethe-Salpeter equation (BSE) for bound states in scalar theories is reformulated and solved for arbitrary scattering kernels in terms of a generalized spectral representation directly in Minkowski space. This differs from the conventional Euclidean approach, where the BSE can only be solved in ladder approximation after a Wick rotation. (author)

  1. Correlation functions of the spin chains. Algebraic Bethe Ansatz approach

    International Nuclear Information System (INIS)

    2007-09-01

    Spin chains are the basic elements of integrable quantum models. These models have direct applications in condense matter theory, in statistical physics, in quantum optics, in field theory and even in string theory but they are also important because they enable us to solve, in an exact manner, non-perturbative phenomena that otherwise would stay unresolved. The method described in this work is based on the algebraic Bethe Ansatz. It is shown how this method can be used for the computation of null temperature correlation functions of the Heisenberg 1/2 spin chain. The important point of this approach is the solution of the inverse quantum problem given by the XXZ spin chain. This solution as well as a simple formulae for the scalar product of the Bethe states, have enabled us to get the most basic correlation functions under the form of multiple integrals. The formalism of multiple integrals open the way for asymptotic analysis for a few physical quantities like the probability of vacuum formation. It is worth noticing that this formalism can give exact results for two-point functions that are the most important correlation functions for applications. A relationship has been discovered between these multiple integrals and the sum of the form factors. The results have been extended to dynamical correlation functions. (A.C.)

    2018-03-01

    In this paper and upcoming ones, we initiate a systematic study of Bethe ansatz equations for integrable models by modern computational algebraic geometry. We show that algebraic geometry provides a natural mathematical language and powerful tools for understanding the structure of solution space of Bethe ansatz equations. In particular, we find novel efficient methods to count the number of solutions of Bethe ansatz equations based on Gröbner basis and quotient ring. We also develop analytical approach based on companion matrix to perform the sum of on-shell quantities over all physical solutions without solving Bethe ansatz equations explicitly. To demonstrate the power of our method, we revisit the completeness problem of Bethe ansatz of Heisenberg spin chain, and calculate the sum rules of OPE coefficients in planar N=4 super-Yang-Mills theory.

  8. Low-temperature excitations within the Bethe approximation

    International Nuclear Information System (INIS)

    Biazzo, I; Ramezanpour, A

    2013-01-01

    We propose the variational quantum cavity method to construct a minimal energy subspace of wavevectors that are used to obtain some upper bounds for the energy cost of the low-temperature excitations. Given a trial wavefunction we use the cavity method of statistical physics to estimate the Hamiltonian expectation and to find the optimal variational parameters in the subspace of wavevectors orthogonal to the lower-energy wavefunctions. To this end, we write the overlap between two wavefunctions within the Bethe approximation, which allows us to replace the global orthogonality constraint with some local constraints on the variational parameters. The method is applied to the transverse Ising model and different levels of approximations are compared with the exact numerical solutions for small systems. (paper)

    2013-07-01

    The Green function formalism is a powerful tool to calculate not only electronic structure within the quasi-particle (QP) picture, but it also gives access to optical absorption spectra. Starting from QP energies within the GW method, the polarizability, as central quantity, is calculated from the solution of a Bethe-Salpeter-like equation (BSE). It is usually solved within the Tamm-Dancoff Approximation (TDA) which neglects the coupling of resonant (positive frequency branch) and anti-resonant (negative frequency branch) excitations. In this work we solve the full BSE (beyond TDA) based on self-consistently calculated QP orbitals and energies for typical systems. The dielectric function is averaged over many low dimensional shifted k-meshes to obtain k-point converged results. We compare the results to recently introduced approximation to the BSE kernel. Additionally, the time-evolution ansatz is employed to calculate the polarizability, which avoids the direct solution of the BSE.

    By combining the algebraic Bethe ansatz and the off-diagonal Bethe ansatz, we investigate the trigonometric SU (3) model with generic open boundaries. The eigenvalues of the transfer matrix are given in terms of an inhomogeneous T - Q relation, and the corresponding eigenstates are expressed in terms of nested Bethe-type eigenstates which have well-defined homogeneous limit. This exact solution provides a basis for further analyzing the thermodynamic properties and correlation functions of the anisotropic models associated with higher rank algebras.

  14. Heisenberg XXX Model with General Boundaries: Eigenvectors from Algebraic Bethe Ansatz

    2013-11-01

    Full Text Available We propose a generalization of the algebraic Bethe ansatz to obtain the eigenvectors of the Heisenberg spin chain with general boundaries associated to the eigenvalues and the Bethe equations found recently by Cao et al. The ansatz takes the usual form of a product of operators acting on a particular vector except that the number of operators is equal to the length of the chain. We prove this result for the chains with small length. We obtain also an off-shell equation (i.e. satisfied without the Bethe equations formally similar to the ones obtained in the periodic case or with diagonal boundaries.

C: Solid State Phys. 7 179) and is devoted to the calculations of average conductivity of random resistor networks placed on an anisotropic Bethe lattice. The structure of the Bethe lattice is assumed to represent the normal directions of the regular lattice. We calculate the anisotropic conductivity as an expansion in powers of the inverse coordination number of the Bethe lattice. The expansion terms retained deliver an accurate approximation of the conductivity at resistor concentrations above the percolation threshold. We make a comparison of our analytical results with those of Bernasconi (1974 Phys. Rev. B 9 4575) for the regular lattice.

    Full Text Available Although forgotten in both Religionswissenschaft (the Science of Religion and psychology, Marianne Beth (1880-1984, initially trained as a lawyer and already in 1928 called a “leading European woman”, must be considered as one of the female pioneers of these fields. She has been active especially in the psychology of religion, a field in which she, together with her husband Karl Beth, founded a research institute, an international organization and a journal. In 1932, the Beths organized in Vienna (where Karl was a professor the largest conference ever in the history of the psychology of religion. Because of her Jewish descent, Marianne Beth fled to the USA when Austria was annexed by Nazi Germany in 1938. This brought an abrupt end to her career as researcher and writer. The article reconstructs Marianne Beth’s path into psychology, analyzes some of her work and puts her achievements in an international perspective.

  6. A systematic approach to sketch Bethe-Salpeter equation

    Directory of Open Access Journals (Sweden)

    Qin Si-xue

    2016-01-01

    Full Text Available To study meson properties, one needs to solve the gap equation for the quark propagator and the Bethe-Salpeter (BS equation for the meson wavefunction, self-consistently. The gluon propagator, the quark-gluon vertex, and the quark–anti-quark scattering kernel are key pieces to solve those equations. Predicted by lattice-QCD and Dyson-Schwinger analyses of QCD’s gauge sector, gluons are non-perturbatively massive. In the matter sector, the modeled gluon propagator which can produce a veracious description of meson properties needs to possess a mass scale, accordingly. Solving the well-known longitudinal Ward-Green-Takahashi identities (WGTIs and the less-known transverse counterparts together, one obtains a nontrivial solution which can shed light on the structure of the quark-gluon vertex. It is highlighted that the phenomenologically proposed anomalous chromomagnetic moment (ACM vertex originates from the QCD Lagrangian symmetries and its strength is proportional to the magnitude of dynamical chiral symmetry breaking (DCSB. The color-singlet vector and axial-vector WGTIs can relate the BS kernel and the dressed quark-gluon vertex to each other. Using the relation, one can truncate the gap equation and the BS equation, systematically, without violating crucial symmetries, e.g., gauge symmetry and chiral symmetry.

  7. Quarkonia in the Bethe--Salpeter formalism with background fields

    International Nuclear Information System (INIS)

    Mathur, Y.K.; Mitra, A.N.

    1989-01-01

    A QCD-oriented Bethe--Salpeter (BS) equation for a q bar q system is formulated in which the quark 4-momenta p μ are modified as p μ →p μ -gA μ (x) in the inverse propagators therein, and a Fock--Schwinger (FS) gauge expansion is employed for the gluon fields A μ (x). The first term (∼x μ ) of the FS representation yields a harmonic kernel when the BS equation is reduced to a 3-dimensional level via the null-plane ansatz (NPA). It also generates a spin-dependent interaction proportional to (j 1 +s 1 )·(j 2 +s 2 ), in close parallel to a J·S term generated by a vector-like (γ (1) gamma(2)) harmonic model for the q bar q interaction proposed earlier by the Delhi Group. A possible mechanism for confinement in an asymptotically linear scene is proposed within the BS framework, taking cue partly from the suggestions of multiple correlation effects (Shifman), and partly from the postulation of stochastic fields (Simonov)

    In 1956 the Enrico Fermi Presidential Award was established to recognize scientists, engineers, and science policymakers who gave unstintingly over their careers to advance energy science and technology. The first recipient was John von Neumann. .1 Among those scientists who were thought eligible for the award were Hans Bethe, J. Robert Oppenheimer, and Edward Teller. In 1959 Norris Bradbury was asked to comment on the relative merits of each these three men, whom he knew well from their affiliation with Los Alamos. Below is a reproduction of the letter Bradbury sent to Dr. Warren C. Johnson of the AEC’s General Advisory Committee(GAC) containing his evaluation of each man. The letter might surprise those not accustomed to Bradbury’s modus operandi of providing very detailed and forthright answers to the AEC. The letter, itself, was found in cache of old microfilm. Whether because of the age of the microfilm or the quality of the filming process, portions of the letter are not legible. Where empty brackets appear, the word or words could not be read or deduced. Words appearing in brackets are guesses that appear, from the image, to be what was written. These guesses, of course, are just that – guesses.

    Israel (along with the US, Japan, Canada, the Russian Federation and India) is one of the CERN non- Member State nations targeted for substantial future participation in CERN's experimental programme, in particular for the LHC proton collider to be built in the 27-kilometre LEP tunnel and which was formally approved by CERN Council in December (January/February, page 1). In keeping with their illustrious scientific traditions, Israeli experimental physicists have collaborated in experiments at many of the world's major high energy Laboratories - Brookhaven, Fermilab and SLAC in the US, and in Europe, DESY, Hamburg, as well as CERN. However CERN, as the geographically closest major Laboratory (as well as the largest), plays a special role for Israeli scientists. At CERN, the advent of preparations in the early 1980s for the experimental programme at the LEP electron-positron collider was the signal for Israeli researchers to mount a concerted effort and contribute to one of the experiments - Opal - at a level comparable to that of major nations. This allowed Israeli teams to participate fully in the planning and construction phase of this branch of Big Science. Underlining this commitment, and to coordinate the various national agencies involved in this aspect of Big Science, in 1983 the Israel Commission for High Energy Physics (ICHEP) was formed. It is currently chaired by David Horn of Tel Aviv. The initial ICHEP/CERN contract established the official CERN/lsrael link under which, in the short-term, teams from three major research centres - the Weizmann Institute, Tel- Aviv University, and Haifa's Technion - contributed to Opal, as the flagship experiment, while providing a framework for longer-term collaboration. (At CERN, Israeli physicists also participate in the NA45 heavy ion experiment and the NA47 Spin Muon Collaboration - SMC.) Opal groups some 320 scientists from 32 research centres in eight countries, and includes a 21-strong Israeli

    The practice of neonatology in Israel debuted in the 1970s as local enterprises by individual hospitals that needed to provide sick and preterm newly born infants with up-to-date and effective care. Descriptions of research and advances in humane and gentle treatment during neonatal care for preterm infants and their families, as well as prevention of neonatal infections, follow-up of preterm infants and care of full-term infants are presented in this issue. The Israel National Very Low Birth Weight (VLBW) Infant database provides an excellent source of knowledge, which has led to multiple scientific publications. Recent international comparisons of the outcome of preterm VLBW infants, made possible by this unique database in Israel, has provided the neonatal community and the Ministry of Health with insights as to the differences in prognosis between Israel and other countries, especially among extremely low birth weight infants. At the border of viability, mortality in Israelis significantly higher than that reported in other countries and proactive steps undertaken to examine these differences and prompt correctional action should be pursued. The Israel Ministry of Health started positive initiatives and should ensure that their steps are implemented at the preterm infant's bedside.

    Takahashi and Suzuki (TS) using the Bethe ansatz method developed a formalism for the thermodynamics of the XYZ spin chain. Translating their formalism to the quantum sine-Gordon system, the thermodynamics and finite temperature elementary excitations are analyzed. Criteria imposed by TS on the allowed states simply correspond to the condition of normalizability of the wave functions. A set of coupled nonlinear integral equations for the thermodynamic equilibrium densities for particular values of the coupling constant in the attractive regime is derived. Solving numerically these Bethe ansatz equations, curves of the specific heat as a function of temperature are obtained. The soliton contribution peaks at a temperature of about 0.4 soliton masses shifting downward as the classical limit is approached. The weak coupling regime is analyzed by deriving the Bethe ansatz equations including the charged vacuum excitations. It is shown that they are necessary for a consistent presentation of the thermodynamics

    2018-04-01

    We study degenerations of Bethe subalgebras B( C) in the Yangian Y(gl_n), where C is a regular diagonal matrix. We show that closure of the parameter space of the family of Bethe subalgebras, which parameterizes all possible degenerations, is the Deligne-Mumford moduli space of stable rational curves \\overline{M_{0,n+2}}. All subalgebras corresponding to the points of \\overline{M_{0,n+2}} are free and maximal commutative. We describe explicitly the "simplest" degenerations and show that every degeneration is the composition of the simplest ones. The Deligne-Mumford space \\overline{M_{0,n+2}} generalizes to other root systems as some De Concini-Procesi resolution of some toric variety. We state a conjecture generalizing our results to Bethe subalgebras in the Yangian of arbitrary simple Lie algebra in terms of this De Concini-Procesi resolution.

    2017-07-01

    We propose a new numerical method to compute the parton distribution amplitude (PDA) from the Euclidean Bethe-Salpeter wave function. The essential step is to extract the weight function in the Nakanishi representation of the Bethe-Salpeter wave function in Euclidean space, which is an ill-posed inversion problem, via the maximum entropy method (MEM). The Nakanishi weight function as well as the corresponding light-front parton distribution amplitude (PDA) can be well determined. We confirm prior work on PDA computations, which was based on different methods.

    Full Text Available We study quantum integrable models solvable by the nested algebraic Bethe ansatz and possessing gl(m|n-invariant R-matrix. We compute the norm of the Hamiltonian eigenstates. Using the notion of a generalized model we show that the square of the norm obeys a number of properties that uniquely fix it. We also show that a Jacobian of the system of Bethe equations obeys the same properties. In this way we prove a generalized Gaudin hypothesis for the norm of the Hamiltonian eigenstates.

    The exact Bethe eigenfunctions for the heptagonal ring within the isotropic XXX model exhibit a doubly degenerated energy level in the three-deviation sector at the centre of the Brillouin zone. We demonstrate an explicit construction of these eigenfunctions by use of algebraic Bethe Ansatz, and point out a relation of degeneracy to parity conservation, applied to the configuration of strings for these eigenfunctions. Namely, the internal structure of the eigenfunctions (the 2-string and the 1-string, with opposite quasimomenta) admits generation of two mutually orthogonal eigenfunctions due to the fact that the strings which differ by their length are distinguishable objects.

    The implementation of the algebraic Bethe ansatz for the XXZ Heisenberg spin chain in the case, when both reflection matrices have the upper-triangular form is analyzed. The general form of the Bethe vectors is studied. In the particular form, Bethe vectors admit the recurrent procedure, with an appropriate modification, used previously in the case of the XXX Heisenberg chain. As expected, these Bethe vectors yield the strikingly simple expression for the off-shell action of the transfer matrix of the chain as well as the spectrum of the transfer matrix and the corresponding Bethe equations. As in the XXX case, the so-called quasi-classical limit gives the off-shell action of the generating function of the corresponding trigonometric Gaudin Hamiltonians with boundary terms.

  15. Distinct solutions of infinite U Hubbard model through nested Bethe ansatz and Gutzwiller projection operator approach

    International Nuclear Information System (INIS)

    Mishra, A.K.; Kishore, R.

    2009-01-01

    The exact nested Bethe ansatz solution for the one dimensional (1-D) U infinity Hubbard model show that the state vectors are a product of spin-less fermion and spin wavefunctions, or an appropriate superposition of such factorized wavefunctions. The spin-less fermion component of the wavefunctions ensures no double occupancy at any site. It had been demonstrated that the nested Bethe ansatz wavefunctions in the U infinity limit obey orthofermi statistics. Gutzwiller projection operator formalism is the another well known technique employed to handle U infinity Hubbard model. In general, this approach does not lead to spin-less fermion wavefunctions. Therefore, the nested Bethe ansatz and Gutzwiller projection operator approach give rise to different kinds of the wavefunctions for the U infinity limit of 1-D Hubbard Hamiltonian. To compare the consequences of this dissimilarity in the wavefunctions, we have obtained the ground state energy of a finite system consisting of three particles on a four site closed chain. It is shown that in the nested Bethe ansatz implemented through orthofermion algebra, all the permissible 2 3 spin configurations are degenerate in the ground state. This eight fold degeneracy of the ground state is absent in the Gutzwiller projection operator approach. This finding becomes relevant in the context of known exact U infinity results, which require that all the energy levels are 2 N -fold degenerate for an N particle system.

    Our study is based on the work of Stinchcombe (1974 J. Phys. C: Solid State Phys. 7 179) and is devoted to the calculations of average conductivity of random resistor networks placed on an anisotropic Bethe lattice. The structure of the Bethe lattice is assumed to represent the normal directions of the regular lattice. We calculate the anisotropic conductivity as an expansion in powers of the inverse coordination number of the Bethe lattice. The expansion terms retained deliver an accurate approximation of the conductivity at resistor concentrations above the percolation threshold. We make a comparison of our analytical results with those of Bernasconi (1974 Phys. Rev. B 9 4575) for the regular lattice.

    Tanaka, Kazuyuki; Shouno, Hayaru; Okada, Masato; Titterington, D M

    2004-01-01

    We investigate the accuracy of statistical-mechanical approximations for the estimation of hyperparameters from observable data in probabilistic image processing, which is based on Bayesian statistics and maximum likelihood estimation. Hyperparameters in statistical science correspond to interactions or external fields in the statistical-mechanics context. In this paper, hyperparameters in the probabilistic model are determined so as to maximize a marginal likelihood. A practical algorithm is described for grey-level image restoration based on a Gaussian graphical model and the Bethe approximation. The algorithm corresponds to loopy belief propagation in artificial intelligence. We examine the accuracy of hyperparameter estimation when we use the Bethe approximation. It is well known that a practical algorithm for probabilistic image processing can be prescribed analytically when a Gaussian graphical model is adopted as a prior probabilistic model in Bayes' formula. We are therefore able to compare, in a numerical study, results obtained through mean-field-type approximations with those based on exact calculation

    Full Text Available For generic values of q, all the eigenvectors of the transfer matrix of the Uqsl(2-invariant open spin-1/2 XXZ chain with finite length N can be constructed using the algebraic Bethe ansatz (ABA formalism of Sklyanin. However, when q is a root of unity (q=eiπ/p with integer p≥2, the Bethe equations acquire continuous solutions, and the transfer matrix develops Jordan cells. Hence, there appear eigenvectors of two new types: eigenvectors corresponding to continuous solutions (exact complete p-strings, and generalized eigenvectors. We propose general ABA constructions for these two new types of eigenvectors. We present many explicit examples, and we construct complete sets of (generalized eigenvectors for various values of p and N.

  10. The q-deformed analogue of the Onsager algebra: Beyond the Bethe ansatz approach

    2006-01-01

    The spectral properties of operators formed from generators of the q-Onsager non-Abelian infinite-dimensional algebra are investigated. Using a suitable functional representation, all eigenfunctions are shown to obey a second-order q-difference equation (or its degenerate discrete version). In the algebraic sector associated with polynomial eigenfunctions (or their discrete analogues), Bethe equations naturally appear. Beyond this sector, where the Bethe ansatz approach is not applicable in related massive quantum integrable models, the eigenfunctions are also described. The spin-half XXZ open spin chain with general integrable boundary conditions is reconsidered in light of this approach: all the eigenstates are constructed. In the algebraic sector which corresponds to special relations among the parameters, known results are recovered

    2006-01-01

    In the history of behaviorism the paper of the three physiologists Theodor Beer, Albrecht Bethe and Jakob von Uexküll from 1899 plays an important role. Many researchers were influenced by this paper and identified it as fundamental for objective psychological research. But during the period of its adoption (1900-1925) psychologists did not notice that Beer, Bethe and Uexküll had distanced themselves from their own paper, because it had been ignored in physiological and biological discussions. Moreover, one of the three (Beer) had to resign from the scientific community because of private scandal and another one (Uexküll) changed all of his views and left the base of objective science for subjective vitalism. However, this did not change his adoption of behaviorism.

    Full Text Available We study the linear problem associated with modified affine Toda field equation for the Langlands dual gˆ∨, where gˆ is an untwisted affine Lie algebra. The connection coefficients for the asymptotic solutions of the linear problem are found to correspond to the Q-functions for g-type quantum integrable models. The ψ-system for the solutions associated with the fundamental representations of g leads to Bethe ansatz equations associated with the affine Lie algebra gˆ. We also study the A2r(2 affine Toda field equation in massless limit in detail and find its Bethe ansatz equations as well as T–Q relations.

  13. Covariant solutions of the Bethe-Salpeter equation and an application to the nucleon structure function

    International Nuclear Information System (INIS)

    Williams, A.G.

    1998-01-01

    There is a need for covariant solutions of bound state equations in order to construct realistic QCD based models of mesons and baryons. Furthermore, we ideally need to know the structure of these bound states in all kinematical regimes, which makes a direct solution in Minkowski space (without any 3-dimensional reductions) desirable. The Bethe-Salpeter equation (BSE) for bound states in scalar theories is reformulated and solved for arbitrary scattering kernels in terms of a generalized spectral representation directly in Minkowski space. This differs from the conventional Euclidean approach, where the BSE can only be solved in ladder approximation after a Wick rotation. An application of covariant Bethe-Salpeter solutions to a quark-diquark model of the nucleon is also briefly discussed. (orig.)

    We apply previous results on the O(N) Bethe Ansatz http://dx.doi.org/10.1088/1751-8113/45/5/055207, http://arxiv.org/abs/1204.3479, http://dx.doi.org/10.1007/JHEP11(2013)089 to construct a general form factor formula for the O(N) Gross-Neveu model. We examine this formula for several operators, such as the energy momentum, the spin-field and the current. We also compare these results with the 1/N expansion of this model and obtain full agreement. We discuss bound state form factors, in particular for the three particle form factor of the field. In addition for the two particle case we prove a recursion relation for the K-functions of the higher level Bethe Ansatz.

  15. Numerical studies of the Bethe-Salpeter equation for a two-fermion bound state

    Science.gov (United States)

    de Paula, W.; Frederico, T.; Salmè, G.; Viviani, M.

    2018-03-01

    Some recent advances on the solution of the Bethe-Salpeter equation (BSE) for a two-fermion bound system directly in Minkowski space are presented. The calculations are based on the expression of the Bethe-Salpeter amplitude in terms of the so-called Nakanishi integral representation and on the light-front projection (i.e. the integration of the light-front variable k - = k 0 - k 3). The latter technique allows for the analytically exact treatment of the singularities plaguing the two-fermion BSE in Minkowski space. The good agreement observed between our results and those obtained using other existing numerical methods, based on both Minkowski and Euclidean space techniques, fully corroborate our analytical treatment.

    Spin chains are the basic elements of integrable quantum models. These models have direct applications in condense matter theory, in statistical physics, in quantum optics, in field theory and even in string theory but they are also important because they enable us to solve, in an exact manner, non-perturbative phenomena that otherwise would stay unresolved. The method described in this work is based on the algebraic Bethe Ansatz. It is shown how this method can be used for the computation of null temperature correlation functions of the Heisenberg 1/2 spin chain. The important point of this approach is the solution of the inverse quantum problem given by the XXZ spin chain. This solution as well as a simple formulae for the scalar product of the Bethe states, have enabled us to get the most basic correlation functions under the form of multiple integrals. The formalism of multiple integrals open the way for asymptotic analysis for a few physical quantities like the probability of vacuum formation. It is worth noticing that this formalism can give exact results for two-point functions that are the most important correlation functions for applications. A relationship has been discovered between these multiple integrals and the sum of the form factors. The results have been extended to dynamical correlation functions. (A.C.)

    We develop the technique of Thermodynamic Bethe Ansatz to investigate the ground state and the spectrum in the thermodynamic limit of the staggered $XXZ$ models proposed recently as an example of integrable ladder model. This model appeared due to staggered inhomogeneity of the anisotropy parameter $\\Delta$ and the staggered shift of the spectral parameter. We give the structure of ground states and lowest lying excitations in two different phases which occur at zero temperature.

    A system of O(N)-matrix difference equations is solved by means of the off-shell version of the nested algebraic Bethe ansatz. In the nesting process, a new object, the Π-matrix, is introduced to overcome the complexities of the O(N)-group structure. The highest weight property of the solutions is proved and some explicit examples are discussed. (paper)

    The representation of scalar products of Bethe wave functions in terms of dual fields, plays an important role in the theory of completely integrable models. The proof is based on the explicit expression for the open-quotes seniorclose quotes coefficient, which was guessed in the Izergin paper and then proved to satisfy some recurrent relations, which determine it unambiguously. In this paper we present an alternative proof based on direct computation. It uses the operation of comultiplication in the ABCD-algebra

A generalization that includes the field of a plane electromagnetic wave is proposed. The rate of one-photon annihilation of positronium in this field is calculated. If the one-photon decay is allowed, the stationary states of the system are found (states of light-positronium)

  9. Long-range psu(2,2|4) Bethe ansatze for gauge theory and strings

    International Nuclear Information System (INIS)

    Beisert, Niklas; Staudacher, Matthias

    2005-01-01

    We generalize various existing higher-loop Bethe ansatze for simple sectors of the integrable long-range dynamic spin chain describing planar N=4 super-Yang-Mills theory to the full psu(2,2|4) symmetry and, asymptotically, to arbitrary loop order. We perform a large number of tests of our conjectured equations, such as internal consistency, comparison to direct three-loop diagonalization and expected thermodynamic behavior. In the special case of the su(1|2) subsector, corresponding to a long-range t-J model, we are able to derive, up to three loops, the S-matrix and the associated nested Bethe ansatz from the gauge theory dilatation operator. We conjecture novel all-order S-matrices for the su(1|2) and su(1,1|2) subsectors, and show that they satisfy the Yang-Baxter equation. Throughout the paper, we muse about the idea that quantum string theory on AdS 5 xS 5 is also described by a psu(2,2|4) spin chain. We propose asymptotic all-order Bethe equations for this putative ''string chain'', which differ in a systematic fashion from the gauge theory equations

  10. The connection of two-particle relativistic quantum mechanics with the Bethe-Salpeter equation

    International Nuclear Information System (INIS)

    Sazdjian, H.

    1986-02-01

    We show the formal equivalence between the wave equations of two-particle relativistic quantum mechanics, based on the manifestly covariant hamiltonian formalism with constraints, and the Bethe-Salpeter equation. This is achieved by algebraically transforming the latter so as to separate it into two independent equations which match the equations of hamiltonian relativistic quantum mechanics. The first equation determines the relative time evolution of the system, while the second one yields a three-dimensional eigenvalue equation. A connection is thus established between the Bethe-Salpeter wave function and its kernel on the one hand and the quantum mechanical wave function and interaction potential on the other. For the sector of solutions of the Bethe-Salpeter equation having non-relativistic limits, this relationship can be evaluated in perturbation theory. We also device a generalized form of the instantaneous approximation which simplifies the various expressions involved in the above relations. It also permits the evaluation of the normalization condition of the quantum mechanical wave function as a three-dimensional integral

  11. Electronic structure of disordered binary alloys with short range correlation in Bethe lattice

    Moreno, I.F.

    1987-01-01

    The determination of the electronic structure of a disordered material along the tight-binding model when applied to a Bethe lattice. The diagonal as well as off-diagonal disorder, are considered. The coordination number on the Bethe is fixed lattice to four (Z=4) that occurs in most compound semiconductors. The main proposal was to study the conditions under which a relatively simple model of a disordered material, i.e, a binary alloy, could account for the basic properties of transport or more specifically for the electronic states in such systems. By using a parametrization of the pair probability the behaviour of the electronic density of states (DOS) for different values of the short range order parameter, σ, which makes possible to treat the segregated, random and alternating cases, was analysed. In solving the problem via the Green function technique in the Wannier representation a linear chain of atoms was considered and using the solution of such a 1-D system the problem of the Bethe lattice which is constructed using such renormalized chains as elements, was solved. The results indicate that the obtained DOS are strongly dependent on the correlation assumed for the occupancy in the lattice. (author) [pt

  12. Loop expansion around the Bethe approximation through the M-layer construction

    Altieri, Ada; Chiara Angelini, Maria; Lucibello, Carlo; Parisi, Giorgio; Ricci-Tersenghi, Federico; Rizzo, Tommaso

    2017-11-01

    For every physical model defined on a generic graph or factor graph, the Bethe M-layer construction allows building a different model for which the Bethe approximation is exact in the large M limit, and coincides with the original model for M=1 . The 1/M perturbative series is then expressed by a diagrammatic loop expansion in terms of so-called fat diagrams. Our motivation is to study some important second-order phase transitions that do exist on the Bethe lattice, but are either qualitatively different or absent in the corresponding fully connected case. In this case, the standard approach based on a perturbative expansion around the naive mean field theory (essentially a fully connected model) fails. On physical grounds, we expect that when the construction is applied to a lattice in finite dimension there is a small region of the external parameters, close to the Bethe critical point, where strong deviations from mean-field behavior will be observed. In this region, the 1/M expansion for the corrections diverges, and can be the starting point for determining the correct non-mean-field critical exponents using renormalization group arguments. In the end, we will show that the critical series for the generic observable can be expressed as a sum of Feynman diagrams with the same numerical prefactors of field theories. However, the contribution of a given diagram is not evaluated by associating Gaussian propagators to its lines, as in field theories: one has to consider the graph as a portion of the original lattice, replacing the internal lines with appropriate one-dimensional chains, and attaching to the internal points the appropriate number of infinite-size Bethe trees to restore the correct local connectivity of the original model. The actual contribution of each (fat) diagram is the so-called line-connected observable, which also includes contributions from sub-diagrams with appropriate prefactors. In order to compute the corrections near to the critical

    Geological surveys have confirmed the existence of substantial Israeli oil shale reserves. The proven reserves contain approximately 12 billion tons of available ores, and the potential is deemed to be much higher. Economic studies conducted by PAMA indicate promising potential for power generation via Israel oil shale combustion. Electric power from oil shale appears competitive with power generated from coal fired power plants located along the coast. PAMA's demonstration power plant has been in operation since the end of 1989. Based on the successful results of the first year of operation, PAMA and IEC are now engaged in the pre-project program for a 1000 MW commercial oil shale fired power plant, based on eight 120 MW units; the first unit is scheduled to begin operation in 1996

    Various governmental agencies, including the Ministry of Health, the Ministry of Labor and the Israel AEC are responsible for the control of the use of radioactive materials and medical X-ray machines in Israel. Present legislation deals mainly with the legal aspects of the purchase, transport and possession of radioactive materials and the purchase and operation of medical X-ray machines. No legislation refers explicitly to the protection of the worker from ionizing (and non-ionizing) radiation. A special group of experts appointed by the Minister of Labor recently worked out a comprehensive draft law concerning all legal aspects of occupational radiation protection in Israel. Among the main chapters of the draft are: general radiation protection principles, national radiation protection standards, medical supervision of radiation workers, personal monitoring requirements. The present situation with regard to radiation hazard control in Israel and details of the proposed radiation protection law is discussed. (Author)

    1992-07-01

    We have computed the masses, wave functions and sea quark content of mesons in their ground state by integrating the Bethe-Salpeter equation with a stochastic algorithm. This method allows the inclusion of a large set of diagrams. Inspection of the kernel of the equation shows that q-q-bar pairs with similar constituent masses in a singlet spin state exhibit a high bound state which is not present in other pairs. The pion, kaon and eta belongs to this category. 19 refs., 2 figs., 2 tabs

    The framework of Bayesian image restoration for multi-valued images by means of the Q-Ising model with nearest-neighbour interactions is presented. Hyperparameters in the probabilistic model are determined so as to maximize the marginal likelihood. A practical algorithm is described for multi-valued image restoration based on the Bethe approximation. The algorithm corresponds to loopy belief propagation in artificial intelligence. We conclude that, in real world grey-level images, the Q-Ising model can give us good results

    The single-time reduction method proposed in other refs. for the system of two scalar particles is generalized for the case of two-fermion system. A self-consistent procedure of single-time reduction has been constructed both in terms of the Bethe-Salpeter wave function and in terms of the Green's function of two-fermion system. Three-dimensional dynamic equations have been obtained for single-time wave functions and two-time Green's functions of a two-fermion system and the Schroedinger structure of the equations obtained is shown to be a consequence of the causality structure of the local QFT. 32 refs

    We investigate the electromagnetic form factors of the Delta and the Omega baryons within the Poincare-covariant framework of Dyson-Schwinger and Bethe-Salpeter equations. The three-quark core contributions of the form factors are evaluated by employing a quark-diquark approximation. We use a consistent setup for the quark-gluon dressing, the quark-quark bound-state kernel and the quark-photon interaction. Our predictions for the multipole form factors are compatible with available experimental data and quark-model estimates. The current-quark mass evolution of the static electromagnetic properties agrees with results provided by lattice calculations.

    Full Text Available We use the coordinate Bethe ansatz to study the Lieb-Liniger model of a one-dimensional gas of bosons on a finite-sized ring interacting via an attractive delta-function potential. We calculate zero-temperature correlation functions for seven particles in the vicinity of the crossover to a localized solitonic state and study the dynamics of a system of four particles quenched to attractive interactions from the ideal-gas ground state. We determine the time evolution of correlation functions, as well as their temporal averages, and discuss the role of bound states in shaping the postquench correlations and relaxation dynamics.

    We study here the magnetic properties of Y- and Lu- Iron Garnets using the Bethe- Peierls-Weiss method modified to suit complex systems like these Garnets. We consider these Garnets as described by Heisenberg Hamiltonian with two sublattices (a,d) and determine the exchange interaction parameters Jad, Jaa and Jdd by matching the exerimental susceptibility curves. We find Jaa and Jdd to be much smaller than those determined by Néel theory, and consistent with those obtained by the study of spin wave spectra; the spin wave dispersion relation constant obtained using these parameters gives good agreement with the experimental values.

    The nested Bethe ansatz (BA) method is applied to find the eigenvalues and the eigenvectors of the transfer matrix for spin-ladder model with open boundary conditions. Based on the reflection equation, we find the general diagonal solution, which determines the general boundary interaction in the Hamiltonian. We introduce the spin-ladder model with open boundary conditions. By finding the solution K ± of the reflection equation which determines the nontrivial boundary terms in the Hamiltonian, we diagonalize the transfer matrix of the spin-ladder model with open boundary conditions in the framework of nested BA.

We propose a natural higher genus analog of Stieltjes-Bethe equations. Links with branched projective structures and with Hurwitz spaces with ramifications of even order are established. We find a higher genus analog of the genus zero Yang-Yang function (the function generating accessory parameters) and describe its similarity and difference with Bergman tau-function on the Hurwitz spaces.

    The author discusses the extension to the (weakly coupled) Yukawa quantum field theory in two space-time dimensions (Y 2 ), with equal bare masses, of some techniques used in the analysis of particle structure for weakly coupled even P(PHI) 2 . In particular he considers existence, regularity, and decay properties for the inverse two point functions and various Bethe-Salpeter kernels of the theory. These properties suffice to ensure that in the +-2 fermion sectors the mass spectrum is discrete below 2m 0 and the S-matrix is unitary up to 2m 0 + epsilon. (Auth.)

  11. Israel: the Division before Peace

    Directory of Open Access Journals (Sweden)

    Ferran Izquierdo Brichs

    2000-01-01

    Full Text Available The process of the Middle East peace negotiations at the beginning of the 1990s has its roots in the changes in the international system and in Israeli society. The end of the Cold War, the Gulf War in 1990-1991 and globalization forced all the region’s actors to resituate themselves within the new international context. However, Israeli society neither experienced the international changes in the same way as its neighbors nor did it undergo the same evolutionduring the conflict with the Arabs. Because of this, the debate over peace and the future of the occupied territories became a factor for political and ideological division. Influencing this debate were revised conceptions on security, the economy, and the role Israel should play in the world. The Middle East peace talks began because the strongest side in the conflict, Israel’s Labor government, came to perceive that the maintenance of the status quo was negative forits interests. From the Israeli point of view, the conflict had long been considered a zero-sum game despite the Palestinian’s compromises since the construction of the Palestinian State involved handing over part of the territory claimed by the Jews. Recent changes in the perceptions of Israeli’s own interests, though, led some sectors of Jewish society to re-think and diminish the supposed incompatibility between Palestine nationalism and Zionism, which then opened the doors towards peace. For the Labor government, the territorial occupation of all Palestine was no longer a central objective. In fact, the basic interests of the Labor party’s policies shifted due to the globalization of the international system. For Likud and the Zionist revisionists, however, the occupation and the colonization of Eretz Israel still form the basic ideology of the State –of its reason for being– for which even today both are associated with the national interest, together with Israel’s very survival.

    2003-01-01

    The mixed spin-((1)/(2)) and spin-1 Blume-Capel Ising ferrimagnetic system is studied on the Bethe lattice by using the exact recursion equations. Exact expressions for the magnetization, the quadrupolar moment, the Curie temperature and the free energy are found and the phase diagrams are constructed on the Bethe lattice with the coordination numbers q=3, 4, 5 and 6. The existence of a tricritical point is investigated for different values of q. The results are compared with those of other approximate methods and with the exact result on the Bethe lattice by using a discrete nonlinear map and also the exact results that are available for the case of the honeycomb lattice

  13. Bethe ansatz for two-magnon scattering states in 2D and 3D Heisenberg–Ising ferromagnets

    2018-04-01

    Two different versions of Bethe ansatz are suggested for evaluation of scattering two-magnon states in 2D and 3D Heisenberg–Ising ferromagnets on square and simple cubic lattices. It is shown that the two-magnon sector is subdivided on two subsectors related to non-interacting and scattering magnons. The former subsector possess an integrable regular dynamics and may be described by a natural modification of the usual Bethe Ansatz. The latter one is characterized by a non-integrable chaotic dynamics and may be treated only within discrete degenerative version of Bethe Ansatz previously suggested by the author. Some of these results are generalized for multi-magnon states of the Heisenberg–Ising ferromagnet on a D dimensional hyper cubic lattice. Dedicated to the memory of L D Faddeev.

  14. On string solutions of Bethe equations in N=4 supersymmetric Yang-Mills theory

    2007-12-01

    The Bethe equations, arising in description of the spectrum of the dilatation operator for the su(2) sector of the N=4 supersymmetric Yang-Mills theory, are considered in the anti-ferromagnetic regime. These equations are deformation of those for the Heisenberg XXX magnet. It is proven that in the thermodynamic limit roots of the deformed equations group into strings. It is proven that the corresponding Yang's action is convex, which implies uniqueness of solution for centers of the strings. The state formed of strings of length (2n+1) is considered and the density of their distribution is found. It is shown that the energy of such a state decreases as n grows. It is observed that non-analyticity of the left hand side of the Bethe equations leads to an additional contribution to the density and energy of strings of even length. Whence it is concluded that the structure of the anti-ferromagnetic vacuum is determined by the behaviour of exponential corrections to string solutions in the thermodynamic limit and possibly involves strings of length 2.

  15. A Bethe ansatz solvable model for superpositions of Cooper pairs and condensed molecular bosons

    Hibberd, K.E.; Dunning, C.; Links, J.

    2006-01-01

    We introduce a general Hamiltonian describing coherent superpositions of Cooper pairs and condensed molecular bosons. For particular choices of the coupling parameters, the model is integrable. One integrable manifold, as well as the Bethe ansatz solution, was found by Dukelsky et al. [J. Dukelsky, G.G. Dussel, C. Esebbag, S. Pittel, Phys. Rev. Lett. 93 (2004) 050403]. Here we show that there is a second integrable manifold, established using the boundary quantum inverse scattering method. In this manner we obtain the exact solution by means of the algebraic Bethe ansatz. In the case where the Cooper pair energies are degenerate we examine the relationship between the spectrum of these integrable Hamiltonians and the quasi-exactly solvable spectrum of particular Schrodinger operators. For the solution we derive here the potential of the Schrodinger operator is given in terms of hyperbolic functions. For the solution derived by Dukelsky et al., loc. cit. the potential is sextic and the wavefunctions obey PT-symmetric boundary conditions. This latter case provides a novel example of an integrable Hermitian Hamiltonian acting on a Fock space whose states map into a Hilbert space of PT-symmetric wavefunctions defined on a contour in the complex plane

    Martins, M.J.; Melo, C.S.

    2009-01-01

    We apply the algebraic Bethe ansatz developed in our previous paper [C.S. Melo, M.J. Martins, Nucl. Phys. B 806 (2009) 567] to three different families of U(1) integrable vertex models with arbitrary N bond states. These statistical mechanics systems are based on the higher spin representations of the quantum group U q [SU(2)] for both generic and non-generic values of q as well as on the non-compact discrete representation of the SL(2,R) algebra. We present for all these models the explicit expressions for both the on-shell and the off-shell properties associated to the respective transfer matrices eigenvalue problems. The amplitudes governing the vectors not parallel to the Bethe states are shown to factorize in terms of elementary building blocks functions. The results for the non-compact SL(2,R) model are argued to be derived from those obtained for the compact systems by taking suitable N→∞ limits. This permits us to study the properties of the non-compact SL(2,R) model starting from systems with finite degrees of freedom.

    We consider Mellin-Barnes transform of triangle ladder-like scalar diagram in d=4 dimensions. It is shown how multi-fold MB transform of the momentum integral corresponding to any number of rungs is reduced to two-fold MB transform. For this purpose we use Belokurov-Usyukina reduction method for four-dimensional scalar integrals in the position space. The result is represented in terms of Euler ψ-function and its derivatives. We derive new formulas for MB two-fold integration in the complex planes of two complex variables. We demonstrate that these formulas solve Bethe-Salpeter equation. We comment on further applications of solution to Bethe-Salpeter equation for vertices in N=4 supersymmetric Yang-Mills theory. We show that the recursive property of MB transforms observed in the present work for that kind of diagrams has nothing to do with quantum field theory, theory of integral transforms, or with theory of polylogarithms in general, but has an origin in a simple recursive property for smooth functions which can be shown by using basic methods of mathematical analysis.

  1. Semi-classical analysis of the inner product of Bethe states

    International Nuclear Information System (INIS)

    Bettelheim, Eldad; Kostov, Ivan

    2014-01-01

    We study the inner product of two Bethe states, one of which is taken on-shell, in an inhomogeneous XXX chain in the Sutherland limit, where the number of magnons is comparable with the length L of the chain and the magnon rapidities arrange in a small number of macroscopically large Bethe strings. The leading order in the large L limit is known to be expressed through a contour integral of a dilogarithm. Here we derive the sub-leading term. Our analysis is based on a new contour-integral representation of the inner product in terms of a Fredholm determinant. We give two derivations of the sub-leading term. Besides a direct derivation by solving a Riemann–Hilbert problem, we give a less rigorous, but more intuitive derivation by field-theoretical methods. For that we represent the Fredholm determinant as an expectation value in a Fock space of chiral fermions and then bosonize. We construct a collective field for the bosonized theory, the short wave-length part of which may be evaluated exactly, while the long wave-length part is amenable to a 1/L expansion. Our treatment thus results in a systematic 1/L expansion of structure factors within the Sutherland limit. (paper)

  3. A separable approximation of the NN-Paris-potential in the framework of the Bethe-Salpeter equation

    Schwarz, K.; Haidenbauer, J.; Froehlich, J.

    1985-09-01

    The Bethe-Salpeter equation is solved with a separable kernel for the most important nucleon-nucleon partial wave states. We employ the Ernst Shakin-Thaler method in the framework of minimal relativity (Blankenbeckler-Sugar equation) to generate a separable representation of the meson-theoretical Paris potential. These separable interactions, which closely approximate the on-shell- and half-off-shell behaviour of the Paris potential, are then cast into a covariant form for application in the Bethe-Salpeter equation. The role of relativistic effects is discussed with respect to on-shell and off-shell properties of the NN-system. (Author)

  4. Israel y su modernización

    Full Text Available Este artículo trata el problema de la modernización y la modernidad de Israel, utilizando para esto, como marco teórico principal, la visión de Múltiples Modernidades de Shmuel Noah Eisenstadt. De acuerdo a este tipo de análisis cada modernización y modernidad se presenta como una variante que incluye elementos tradicionales y locales del modelo original de la Ilustración. En el caso de Israel, cuya sociedad moderna es mayormente inmigratoria y altamente heterogénea, se podría llegar a argumentar que la multiplicidad se torna en un aspecto interno del proceso. La modernización dialécticamente produce resultados contrarios a las intenciones y planes originales de quienes la ponen en marcha, y esto se manifiesta en el caso de Israel a través del resurgimiento religioso, el retorno a tradiciones e identidades étnicas que precedieron el intento de establecer una sociedad moderna y sus bases ideológicas radicadas en el sionismo, y ello sin dejar de lado la sociedad palestina local –o árabe israelí-, absorbida dentro del marco general de la sociedad israelí.

    The principle deeds of genetics in Israel consist of a wide array of disciplines including agriculture, nutrients, biotechnology, pharmacology and pharmacogenetics, pertaining to criminal as well as medical aspects. In the scope of this state of the art historical review, the authors emphasize the medical issues. The initial stimulus for genetic studies and medical awareness among the various ethnic populations in Israel was the immigration, in the early 1950s, of over a million Jewish immigrants from more than 100 countries from all continents. It was soon recognized that frequencies of genetic diseases differed markedly among the various communities, serving as a trigger for studying and managing these populations. In this state of the art historical review, particular emphasize was given to the historical events concerning genetics in the land of Israel, as well as in the state of Israel. Highlights of genetic diversity of the various ethnic and sub-populations are added, along with the advances and major achievements of the human genetics discipline in the state of Israel.

    Israel maintained that the complex international system and worldwide political tension created a situation in which comprehensive plans of disarmament could not produce any positive result. The deadlock in the field of general and complete disarmament has brought Israel to the realization that one possible way to alleviate the stalemate could be progress by stages through partial measures of disarmament. Israel's position on non-proliferation indicates that the establishment of a nuclear-weapon-free-zone (NWFZ), as it relates to the Middle-East, could serve as a credible alternative to the unilateral adherence to the Non-Proliferation of Nuclear Weapon (NPT) and an effective measure of non-proliferation in the region.

    The electricity sector in the Middle-East is rarely studied, however this energy has a key role in the rivalry between Israelis and Palestinians. Indeed, the Hebrew State uses it as a tool of conquest and control in the West Bank and the Gaza Strip, by giving an access to commodities to Jewish settlers. Moreover, Palestinians are strongly dependent on electricity produced by Israeli power plants, which enables Israel to pressure on the Palestinians. Yet the Palestinian electricity dependence is a critical issue for Israel's security as the Hamas, whose leadership is at stake in the region, knows how to take advantage of the situation

The limited partnership would be suitable for financing a significant portion of the project. Economic feasibility can be estimated through the use of one or more of the approaches supplied by the calculus of variations, cardinal utility theory, catastrophe theory, and noncooperative game theory.

    The technique of projecting the four-dimensional two-body Bethe-Salpeter equation onto the three-dimensional Light-Front hypersurface, combined with the quasi-potential approach, is briefly illustrated, by placing a particular emphasis on the relation between the projection method and the effective dynamics of the valence component of the Light-Front wave function. Some details on how to construct the Fock expansion of both (a) the Light-Front effective interaction and (b) the electromagnetic current operator, satisfying the proper Ward-Takahashi identity, will be presented, addressing the relevance of the Fock content in the operators living onto the Light-Front hypersurface. Finally, the generalization of the formalism to the three-particle case will be outlined. (author)

    2013-01-01

    This article asserts the need to recognize the complexity of the theoretical work of more lesbian Native American writers, focusing specifically Beth Brant (Bay of Quinte Mohawk) and Paula Gunn Allen (Laguna Pueblo). Their poetry and short stories provide a theoretically nuanced analysis of how heteronormativity is intertwined in and dependent on colonialism, and thus a methodology for Queer Theory that requires an understanding of it in relation to colonialism. They reject heteronormative Pocahontas fantasies about Native women, offering a lesbian-based tactic for decolonization through the expression of erotic desire. This article demonstrates the endless possibilities for fierce queer resistance, revolutionary change, and healing from the trauma of genocide and the accompanying colonialist heteropatriarchal disciplining of Native women's bodies.

    We develop an approach to the solution of the spinless Bethe-Salpeter equation for the different-mass case. Although the calculations are developed for spin-zero particles in any arbitrary spherically symmetric potential, the non-Coulombic effective power-law potential is used as a kernel to produce the spin-averaged bound states of the non-self-conjugate mesons. The analytical formulae are also applicable to the self-conjugate mesons in the equal-mass case. The flavor-independent case is investigated in this work. The calculations are carried out to the third-order correction of the energy series. Results are consistent with those obtained before. (author). 14 refs, 1 tab

  4. On Condensation Properties of Bethe Roots Associated with the XXZ Chain

    2018-02-01

    I prove that the Bethe roots describing either the ground state or a certain class of "particle-hole" excited states of the XXZ spin-1/2 chain in any sector with magnetisation m \\in [0;1/2] exist, are uniquely defined, and form, in the infinite volume limit, a dense distribution on a subinterval of R. The results hold for any value of the anisotropy {Δ ≥ -1}. In fact, I establish an even stronger result, namely the existence of an all order asymptotic expansion of the counting function associated with such roots. As a corollary, these results allow one to prove the existence and form of the infinite volume limit of various observables attached to the model -the excitation energy, momentum, the zero temperature correlation functions, so as to name a few- that were argued earlier in the literature.

  5. An investigation of relativistic microscopic optical potential in terms of relativistic Brueckner-Bethe-Goldstone equation

    International Nuclear Information System (INIS)

    Chen Baoqiu; Ma Zhongyu

    1992-01-01

    Relativistic microscopic optical potential of nucleon-nucleus is derived from the relativistic Brueckner-Bethe-Goldstone (RBBG) equation. The complex effective mass of a nucleon is determined by a fit to 200 MeV p- 40 Ca scattering data. The relativistic microscopic optical potentials with this effective mass are obtained from RBBG for p- 16O , 40 Ca, 90 Zr and 208 Pb scattering in energy range from 160 to 800 MeV. The microscopic optical potential is used to study the proton- 40 Ca scattering problem at 200 MeV. The results, such as differential cross section, analyzing power and spin rotation function are compared with those calculated from phenomenological relativistic optical potential

  6. Asymptotic Bethe ansatz S-matrix and Landau-Lifshitz-type effective 2d actions

    International Nuclear Information System (INIS)

    Roiban, R; Tirziu, A; Tseytlin, A A

    2006-01-01

    Motivated by the desire to relate Bethe ansatz equations for anomalous dimensions found on the gauge-theory side of the AdS/CFT correspondence to superstring theory on AdS 5 x S 5 we explore a connection between the asymptotic S-matrix that enters the Bethe ansatz and an effective two-dimensional quantum field theory. The latter generalizes the standard 'non-relativistic' Landau-Lifshitz (LL) model describing low-energy modes of ferromagnetic Heisenberg spin chain and should be related to a limit of superstring effective action. We find the exact form of the quartic interaction terms in the generalized LL-type action whose quantum S-matrix matches the low-energy limit of the asymptotic S-matrix of the spin chain of Beisert, Dippel and Staudacher (BDS). This generalizes to all orders in the 't Hooft coupling λ an earlier computation of Klose and Zarembo of the S-matrix of the standard LL model. We also consider a generalization to the case when the spin-chain S-matrix contains an extra 'string' phase and determine the exact form of the LL 4-vertex corresponding to the low-energy limit of the ansatz of Arutyunov, Frolov and Staudacher (AFS). We explain the relation between the resulting 'non-relativistic' non-local action and the second-derivative string sigma model. We comment on modifications introduced by strong-coupling corrections to the AFS phase.

    We study the model of a discrete directed polymer (DP) on a square lattice with homogeneous inverse gamma distribution of site random Boltzmann weights, introduced by Seppalainen (2012 Ann. Probab. 40 19–73). The integer moments of the partition sum, Z n -bar , are studied using a transfer matrix formulation, which appears as a generalization of the Lieb–Liniger quantum mechanics of bosons to discrete time and space. In the present case of the inverse gamma distribution the model is integrable in terms of a coordinate Bethe Ansatz, as discovered by Brunet. Using the Brunet-Bethe eigenstates we obtain an exact expression for the integer moments of Z n -bar for polymers of arbitrary lengths and fixed endpoint positions. Although these moments do not exist for all integer n, we are nevertheless able to construct a generating function which reproduces all existing integer moments and which takes the form of a Fredholm determinant (FD). This suggests an analytic continuation via a Mellin–Barnes transform and we thereby propose a FD ansatz representation for the probability distribution function (PDF) of Z and its Laplace transform. In the limit of a very long DP, this ansatz yields that the distribution of the free energy converges to the Gaussian unitary ensemble (GUE) Tracy-Widom distribution up to a non-trivial average and variance that we calculate. Our asymptotic predictions coincide with a result by Borodin et al (2013 Commun. Math. Phys. 324 215–32) based on a formula obtained by Corwin et al (2011 arXiv:1110.3489) using the geometric Robinson–Schensted–Knuth (gRSK) correspondence. In addition we obtain the dependence on the endpoint position and the exact elastic coefficient at a large time. We argue the equivalence between our formula and that of Borodin et al. As we will discuss, this provides a connection between quantum integrability and tropical combinatorics. (paper)

    2017-07-03

    We present an overview of the impact of universal rotavirus immunization with the pentavalent vaccine, RotaTeq, which was introduced in Israel in 2010. The vaccine is given free of charge at age 2, 4 and 6 months, with an 80% coverage that was shortly achieved during the universal immunization period. Compared to pre-universal immunization years (2008-2010), a reduction of 66-68% in the incidence of rotavirus gastroenteritis (RVGE) hospitalizations was observed in 2011-2015 among children aged 0-23 months in central and northern Israel. In southern Israel a reduction of 80-88% in RVGE hospital visit rate was found among Jewish children aged 0-23 months in 2011-2013. Among Bedouins, the respective decline was 62-75%. A significant reduction of 59% was also observed in RVGE clinic visits, presumably representing less severe illness. Indirect benefit was evident in children aged 24-59 months who were ineligible for universal immunization. Vaccine effectiveness against RVGE hospitalization was estimated at 86% in children aged 6-23 months. Changes in the circulating rotavirus genotypes occurred but the contribution of vaccine induced immune pressure is unclear. Universal rotavirus immunization was followed by an impressive decrease in the burden of RVGE in young children in Israel, likely attributed to good vaccine coverage and effectiveness.

    2008-07-01

    There is a large Ethiopian community in Israel which preserves its unique culture and customs. Many of the members of this community still use traditional methods of healing, such as blood-letting, burns, tattooing, amulets, healing water, incense and various medicinal herbs that are prescribed based on the diagnosis of the disease. This study deals with documenting the use of the medicinal drugs implemented by the Ethiopian community in Israel, which is a rapidly vanishing world. The study is based on interviews with hundreds of informants, among them traditional healers, and it surveyed some fifty shops which sell Ethiopian medicinal drugs and spices. The survey brought to light a list of medical materials which are found in the Ethiopian markets in Israel including 89 kinds of plants (some 85%); 6 different minerals (some 6%); 5 types of animals (some 4.5%); and 5 substances of various origins (some 4.5%). Most of the drugs are imported from Ethiopia to Israel, since they are endemic. There are also other medicinal drugs that are gathered in the field in Israel or brought through personal import; in total, our estimate is that there are approximately 150 different kinds of medicinal drugs in use in Israel. This is a relatively small number when compared to the inventory of drugs in the land of origin, Ethiopia. The decline in the use of traditional drugs, due to limited availability and processes of modernization in the Ethiopian community in Israel, heightens the importance of a study that documents this unique culture. The study is also of assistance to the modern medical authorities in order to better understand and become more familiar with the Ethiopian community and with its needs and special practices, in terms of both prevention and treatment.

  14. Calculation of scalar products of wave functions and form factors in the framework of the algebraic Bethe ansatz

    International Nuclear Information System (INIS)

    Slavnov, N.A.

    1989-01-01

    The Bethe ansatz method is widely used to investigate two-dimensional completely integrable models. In the framework of the quantum inverse scattering method it has proved to be possible to construct an algebraic scheme of the Bethe ansatz, and this has been successfully applied to calculation of correlation functions. One of the important questions of the method is that of the scalar products of the wave functions. In particular, knowledge of the properties of the scalar products is necessary for investigating the form factors and correlation function. In the present paper the author considers a generalized model with R matrix of the model of the nonlinear Schroedinger equation. The main formulas and notation are given in Sec. 2. In Sec. 3 he calculates the scalar product of an arbitrary function and an eigenfunction of the Hamiltonian. The generalized two-site model is introduced in Sec. 4. In Sec. 5 he calculates the form factor of the particle number operator

    We present one reduction of the Bethe-Salpeter equation for the bound states composed of two off-mass-shell constituents. Both the relativistic effects and the virtuality effects can be considered in the obtained spinless virtuality distribution equation. The eigenvalues of the spinless virtuality distribution equation are perturbatively calculated and the bound states e+e-, μ+μ-, τ+τ-, μ+e-, and τ+e- are discussed.

  16. The critical 1-arm exponent for the ferromagnetic Ising model on the Bethe lattice

    Heydenreich, Markus; Kolesnikov, Leonid

    2018-04-01

    We consider the ferromagnetic nearest-neighbor Ising model on regular trees (Bethe lattice), which is well-known to undergo a phase transition in the absence of an external magnetic field. The behavior of the model at critical temperature can be described in terms of various critical exponents; one of them is the critical 1-arm exponent ρ which characterizes the rate of decay of the (root) magnetization as a function of the distance to the boundary. The crucial quantity we analyze in this work is the thermal expectation of the root spin on a finite subtree, where the expected value is taken with respect to a probability measure related to the corresponding finite-volume Hamiltonian with a fixed boundary condition. The spontaneous magnetization, which is the limit of this thermal expectation in the distance between the root and the boundary (i.e., in the height of the subtree), is known to vanish at criticality. We are interested in a quantitative analysis of the rate of this convergence in terms of the critical 1-arm exponent ρ. Therefore, we rigorously prove that ⟨σ0⟩ n +, the thermal expectation of the root spin at the critical temperature and in the presence of the positive boundary condition, decays as ⟨σ0 ⟩ n +≈n-1/2 (in a rather sharp sense), where n is the height of the tree. This establishes the 1-arm critical exponent for the Ising model on regular trees (ρ =1/2 ).

  17. QCD-oriented Bethe-Salpeter dynamics for all flavours, light and heavy

    1987-01-01

    A QCD oriented Bethe-Salpeter approach with a vector-like confinement which looks harmonic in the instantaneous approximation (IA), was found to describe several features of qanti q and qqq systems (mass spectra and structural properties) adequately, with little extra assumptions. The model had the following drawbacks: (a) The IA, being non-covariant, had restricted the application of the model to slow hadrons; (b) The zero-point energies were poorly described without additional assumptions; (c) The predicted Qanti Q spacings were too large for the data. These limitations have recently been overcome and the model now has a wide sweep of successful predictions, not only on the mass spectra for both light and heavy sectors, but also for transition amplitudes involving fast moving hadrons. A sketchy but consolidated account is given of the main features of the model (as modified through the new assumptions) and the nature of its successes on the experimental front (mostly mass spectra) are indicated. 20 refs

  18. Beth-Uhlenbeck approach for repulsive interactions between baryons in a hadron gas

    2018-03-01

    The quantum mechanical Beth-Uhlenbeck (BU) approach for repulsive hard-core interactions between baryons is applied to the thermodynamics of a hadron gas. The second virial coefficient a2—the "excluded volume" parameter—calculated within the BU approach is found to be temperature dependent, and it differs dramatically from the classical excluded volume (EV) model result. At temperatures T =100 -200 MeV, the widely used classical EV model underestimates the EV parameter for nucleons at a given value of the nucleon hard-core radius by large factors of 3-4. Previous studies, which employed the hard-core radii of hadrons as an input into the classical EV model, have to be re-evaluated using the appropriately rescaled EV parameters. The BU approach is used to model the repulsive baryonic interactions in the hadron resonance gas (HRG) model. Lattice data for the second- and fourth-order net baryon susceptibilities are described fairly well when the temperature dependent BU baryonic excluded volume parameter corresponds to nucleon hard-core radii of rc=0.25 -0.3 fm. Role of the attractive baryonic interactions is also considered. It is argued that HRG model with a constant baryon-baryon EV parameter vN N≃1 fm3 provides a simple yet efficient description of baryon-baryon interaction in the crossover temperature region.

  19. Null-plane formulation of Bethe-Salpeter qqq dynamics: Baryon mass spectra

    International Nuclear Information System (INIS)

    Kulshreshtha, D.S.; Mitra, A.N.

    1988-01-01

    The Bethe-Salpeter (BS) equation for a qqq system is formulated in the null-plane approximation (NPA) for the BS wave function, as a direct generalization of a corresponding QCD-motivated formalism developed earlier for qq-bar systems. The confinement kernel is assumed vector type (γ/sub μ//sup (1)/γ/sub μ//sup (2)/) for both qq-bar and qq pairs, with identical harmonic structures, and with the spring constant proportional, among other things, to the running coupling constant α/sub s/ (for an explicit QCD motivation). The harmonic kernel is given a suitable Lorentz-invariant definition [not D'Alembertian 2 δ 4 (q)], which is amenable to NPA reduction in a covariant form. The reduced qqq equation in NPA is solved algebraically in a six-dimensional harmonic-oscillator (HO) basis, using the techniques of SO(2,1) algebra interlinked with S 3 symmetry. The results on the nonstrange baryon mass spectra agree well with the data all the way up to N = 6, thus confirming the asymptotic prediction M∼N/sup 2/3/ characteristic of vector confinement in HO form. There are no extra parameters beyond the three basic constants (ω 0 ,C 0 ,m/sub u//sub d/) which were earlier found to provide excellent fits to meson spectra (qq-bar)

  20. Short-distance behavior of the Bethe--Salpeter wave function in the ladder approximation

    Guth, A.H.; Soper, D.E.

    1975-01-01

    We investigate the short-distance behavior of the (Wick-rotated) Bethe--Salpeter wave function for the two spin-1/2 quarks bound by the exchange of a massive vector meson. We use the ladder-model kernel, which has the same p -4 scaling behavior as the true kernel in a theory with a fixed point of the renormalization group at g not equal to 0. For a bound state with the quantum numbers of the pion, the leading asymptotic behavior is chi (q/sup μ/) approx. cq/sup -4 + epsilon(g)/γ 5 , where epsilon (g) =1- (1-g 2 /π 2 ) 1 / 2 . Our method also provides the full asymptotic series, although it should be noted that the nonleading terms will depend on the nonleading behavior of the ladder-model kernel. A general term has the form cq - /sup a/(lnq)/sup n/phi (q/sup μ/), where c is an unknown constant, a may be integral or nonintegral, n is an integer, and phi (q/sup μ/) is a representation function of the rotation group in four dimensions

  1. A Binary-Encounter-Bethe Approach to Simulate DNA Damage by the Direct Effect

    Science.gov (United States)

    Plante, Ianik; Cucinotta, Francis A.

    2013-01-01

    The DNA damage is of crucial importance in the understanding of the effects of ionizing radiation. The main mechanisms of DNA damage are by the direct effect of radiation (e.g. direct ionization) and by indirect effect (e.g. damage by.OH radicals created by the radiolysis of water). Despite years of research in this area, many questions on the formation of DNA damage remains. To refine existing DNA damage models, an approach based on the Binary-Encounter-Bethe (BEB) model was developed[1]. This model calculates differential cross sections for ionization of the molecular orbitals of the DNA bases, sugars and phosphates using the electron binding energy, the mean kinetic energy and the occupancy number of the orbital. This cross section has an analytic form which is quite convenient to use and allows the sampling of the energy loss occurring during an ionization event. To simulate the radiation track structure, the code RITRACKS developed at the NASA Johnson Space Center is used[2]. This code calculates all the energy deposition events and the formation of the radiolytic species by the ion and the secondary electrons as well. We have also developed a technique to use the integrated BEB cross section for the bases, sugar and phosphates in the radiation transport code RITRACKS. These techniques should allow the simulation of DNA damage by ionizing radiation, and understanding of the formation of double-strand breaks caused by clustered damage in different conditions.

  2. Site-occupation embedding theory using Bethe ansatz local density approximations

    2018-06-01

    Site-occupation embedding theory (SOET) is an alternative formulation of density functional theory (DFT) for model Hamiltonians where the fully interacting Hubbard problem is mapped, in principle exactly, onto an impurity-interacting (rather than a noninteracting) one. It provides a rigorous framework for combining wave-function (or Green function)-based methods with DFT. In this work, exact expressions for the per-site energy and double occupation of the uniform Hubbard model are derived in the context of SOET. As readily seen from these derivations, the so-called bath contribution to the per-site correlation energy is, in addition to the latter, the key density functional quantity to model in SOET. Various approximations based on Bethe ansatz and perturbative solutions to the Hubbard and single-impurity Anderson models are constructed and tested on a one-dimensional ring. The self-consistent calculation of the embedded impurity wave function has been performed with the density-matrix renormalization group method. It has been shown that promising results are obtained in specific regimes of correlation and density. Possible further developments have been proposed in order to provide reliable embedding functionals and potentials.

  3. Bethe-Salpeter equation for fermion-antifermion system in the ladder approximation

    1977-01-01

    The Bethe-Salpeter (B-S) equation is important for studying hadron physics. Especially intensive investigation on the fermion-antifermion B-S equation is indispensable for the phenomenological studies of hardrons. However, many components of the B-S amplitude and the Wick-rotated integral kernel of non-Fredholm type have prevented from knowing details the solutions even in the ladder approximation. Some particular solutions are known in case of the vanishing four-momenta of bound states. The B-S equation for the bound state of fermion-anti-fermion system interacting through vector (axial-vector) particle exchange was studied in the ladder approximation with Feynman gauge. The reduced equations were obtained for suitably decomposed amplitude, and it is shown that, in the S-wave case, the coupled equations separate into two parts. In the nonrelativistic limit, large components of the amplitude satisfy the Wick-Cutkosky equation, and small components are expressed in terms of the large ones. Equations are derived for the equal-time amplitudes. (Kobatake, H.)

    2013-03-01

    After the geographic and sociodemographic settings as well as the health care in Israel are briefly described, the scope of pediatric allergy and immunology in Israel is presented. This includes specific disorders commonly encountered, the environment that induces symptoms, the specialists who treat them, and the common challenges of patients, parents, doctors, and allied health personnel who collaborate to manage the maladies and patient care. Allergies usually affect some overall 15-20% of the pediatric population. The main allergens are inhaled, ingested, or injected (insects stings). Generally, the incidence of the various allergens affecting children in Israel, is similar to other parts of the Western world. Owing to the high consanguinity rate in the Israeli population, the prevalence of the various immunodeficiency conditions (in the adaptive as well as the innate system) is higher than that reported worldwide. Pediatric allergists/immunologists also treat autoimmune disorders affecting the pediatric group. Pediatric allergy and clinical immunology are not separate specialties. The 25 specialists who treat children with allergic/immunologic diseases have undergone a basic training in Pediatrics. They also received an additional 2-yr training in allergy and clinical immunology and then have to pass the board examinations. They work mainly in pediatric allergy units, in several hospitals that are affiliated to the five medical schools in the country. Aside from clinical work, most of the centers are also heavily involved in clinical and basic research in allergy and immunology. © 2013 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

    Shaffer, Brenda

    2011-01-01

    In 2009 and 2010, major offshore natural gas reserves were discovered near the State of Israel. This article examines Israel's newly discovered natural gas reserves and the implications of this discovery for Israel, the Middle East, and the Mediterranean region. The article will discuss Israel's energy security approach; the role of natural gas in Israel's energy consumption patterns; the organization of Israel's natural gas sector; regional political and security implications of the natural gas discoveries; the prospects for export, and the outlook for various natural gas markets. These new discoveries significantly improve Israel's energy security. They may also spur Israel to develop technologies related to utilization of natural gas in a variety of sectors, such as transportation. The discoveries may contribute to the emergence of a number of maritime border delimitation conflicts in the Eastern Mediterranean. At current volumes, the Israeli discoveries will not be a game-changer for gas markets in southern Europe or liquefied natural gas (LNG) markets. However, they will lead to expanded natural gas consumption in the region. In addition, offshore exploration efforts in Israel and in neighboring countries are intensifying. Additional discoveries may turn the Eastern Mediterranean region into a new source of natural gas and oil. - Highlights: → In 2009 and 2010, major natural gas deposits were discovered offshore of Israel's port city of Haifa. → They will satisfy a large portion of Israel's domestic energy consumption needs for a number of decades. → The gas discoveries have created an opportunity to fundamentally change the country's energy policies. → Additional discoveries may turn the Eastern Mediterranean region into a new source of natural gas and oil. → Israel could become a supplier of natural gas to neighbors in the Middle East region, such as Jordan.

    1992-12-01

    The Bethe-Weizsaecker nuclear mass formula is extended to strange hadronic matter composed of nucleons, lambdas and cascade hyperons. The generalized formula contains several volume and symmetry terms constrained by phenomenologically determined λ-nuclear, ξ-nuclear and λλ interaction parameters and by hyperon-hyperon (λλ, λξ, ξξ) interaction parameters suggested by One-Boson-Exchange models. We find that hypernuclei are generally unstable to λλ → ξN conversion. For strange hadronic matter, as function of the baryon number A, the line of strong-interaction stability, along which a large strangeness fraction |S|/A ∼ 0.5 - 1.1 and a low charge fraction q/A approx-lt 0.2 hold, and no fission occurs, is determined. The binding energy per baryon increases monotonically to its bulk limit, B/A → 38 MeV, |S|/A → 1.1 and q/A → 0 for the parameters adopted here assuming that the hyperon species saturate at densities similar to those of protons and neutrons in nuclei. Even in the extreme limit of vanishingly small hyperon-hyperon interaction strengths, strange hadronic matter with B/A → 15 MeV, |S|/A → 0.7 and q/A → 0 in the bulk limit should exist; the mass formula reproduces semi-quantitatively recent mean-field calculations which implicitly assumed weak hyperon-hyperon interactions

For strange hadronic matter we determine, as function of the baryon number A, the line of strong-interaction stability, along which a large strangeness fraction vertical stroke /Svertical stroke /A∝0.5-1.1 and a low charge fraction q/A< or ∼0.2 hold, and no fission occurs.

    We present an efficient implementation of the Bethe-Salpeter equation (BSE) method for obtaining core-level spectra including X-ray absorption (XAS), X-ray emission (XES), and both resonant and non-resonant inelastic X-ray scattering spectra (N/RIXS). Calculations are based on density functional theory (DFT) electronic structures generated either by ABINIT or QuantumESPRESSO, both plane-wave basis, pseudopotential codes. This electronic structure is improved through the inclusion of a GW self energy. The projector augmented wave technique is used to evaluate transition matrix elements between core-level and band states. Final two-particle scattering states are obtained with the NIST core-level BSE solver (NBSE). We have previously reported this implementation, which we refer to as OCEAN (Obtaining Core Excitations from Ab initio electronic structure and NBSE) (Vinson et al., 2011). Here, we present additional efficiencies that enable us to evaluate spectra for systems ten times larger than previously possible; containing up to a few thousand electrons. These improvements include the implementation of optimal basis functions that reduce the cost of the initial DFT calculations, more complete parallelization of the screening calculation and of the action of the BSE Hamiltonian, and various memory reductions. Scaling is demonstrated on supercells of SrTiO3 and example spectra for the organic light emitting molecule Tris-(8-hydroxyquinoline)aluminum (Alq3) are presented. The ability to perform large-scale spectral calculations is particularly advantageous for investigating dilute or non-periodic systems such as doped materials, amorphous systems, or complex nano-structures.

  17. Mixed spin-3/2 and spin-5/2 Ising system on the Bethe lattice

    In order to study the critical behaviors of the half-integer mixed spin-3/2 and spin-5/2 Blume-Capel Ising ferrimagnetic system, we have used the exact recursion relations on the Bethe lattice. The system was studied for the coordination numbers with q=3, 4, 5 and 6, and the obtained phase diagrams are illustrated on the (kT c /|J|,D A /|J|) plane for constant values of D B /|J|, the reduced crystal field of the sublattice with spin-5/2, and on the (kT c /|J|,D B /|J|) plane for constant values of D A /|J|, the reduced crystal field of the sublattice with spin-3/2, for q=3 only, since the cases corresponding to q=4, 5 and 6 reproduce results similar to the case for q=3. In addition we have also presented the phase diagram with equal strengths of the crystal fields for q=3, 4, 5 and 6. Besides the second- and first-order phase transitions, the system also exhibits compensation temperatures for appropriate values of the crystal fields. In this mixed spin system while the second-order phase transition lines never cut the reduced crystal field axes as in the single spin type spin-3/2 and spin-5/2 Ising models separately, the first-order phase transition lines never connect to the second-order phase transition lines and they end at the critical points, therefore the system does not give any tricritical points. In addition to this, this mixed-spin model exhibits one or two compensation temperatures depending on the values of the crystal fields, as a result the compensation temperature lines show reentrant behavior

    A recently published detailed and exhaustive paper on cross-sections for ionisation induced by keV electrons clearly shows that electron phenomena occurring in parallel with X-ray processes may have been dramatically overlooked for many years, mainly when low atomic number species are involved since, in these cases, the fluorescence coefficient is smaller than the Auger yield. An immediate problem is encountered while attempting to tackle the issue. Accounting for electron phenomena requires the knowledge of the stopping power of electrons within, at least, a reasonably small error. Still, the Bethe formula for stopping powers is known to not be valid for electron energies below 30 keV, and its use leads to values far off experimental ones. Recently, a few authors have addressed this problem and both detailed tables of electron stopping powers for various atomic species and attempts to simplify the calculations, have emerged. Nevertheless, its implementation in software routines to efficiently calculate keV electron effects in materials quickly becomes a bit cumbersome. Following a procedure already used to establish efficient methods to calculate ionisation cross-sections by protons and alpha particles, it became clear that a simple polynomial approximation could be set, which allows retrieving the electronic stopping powers with errors of less than 20% for energies above 500 eV and less than 50% for energies between 50 eV and 500 eV. In this work, we present this approximation which, based on just six parameters, allows to recover electron stopping power values that are less than 20% different from recently published experimentally validated tabulated data.

    Quarterly data for Israel are used to compare and contrast three dynamic econometric methodologies for estimating the demand for electricity by households and industrial companies. These are the Dynamic Regression Model and two approaches to cointegration (OLS and Maximum Likelihood). Since we find evidence of seasonal unit roots in the data we also test for seasonal cointegration. We find that the scale elasticities are similar in all three approaches but the OLS price elasticities are considerably lower. Moreover, OLS suggests non-cointegration. The paper concludes by stochastically simulating the DRMs to calculate upside-risk in electricity demand. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam. All rights reserved.)

    Two, three- and four-body contributions to the binding energy of nuclear matter are evaluated in the framework of the Bethe-Brueckner expansion. Special attention is devoted to the choice of the auxillary single particle field and to the potential diagrams at the level of three- and four-hole lines present when such a field is different from zero. Two nucleon-nucleon interactions are used: a model interaction V 1 and the Reid soft-core interaction. For V 1 our results are compared with those obtained from variational calculations; this comparison supports the reliability of the perturbative expansion. (Auth.)

    The Israeli Health Service was established with the intent of providing an equal standard of care to the entire Israeli population. The Health Service has dealt with changes over the years, including the governing of large populations of Judea, Samaria, and Gaza. In 1990, mass immigration brought 500,000 more individuals to Israel, putting an additional burden on medical services. ICUs in Israel began to emerge after the Six Day War in 1967. The government's Ministry of Health has approved a limited amount of ICU beds. Beyond this set amount, hospital directors decide whether to establish additional ICU beds, weighing departmental pressures from within the hospital to create beds against the knowledge that the hospital will not be reimbursed more than the per diem rate of an ordinary hospital bed ($US 265). Hospital directors and administrators, knowing that the average daily cost of an ICU bed is close to $US 800, turn to their supporting organization to finance the uncontrollable deficit, seek aid from the Ministry of Health to make the per diem rates or diagnosis-related group reimbursements more realistic, and/or implement hospital policies aimed at cutting costs and personnel.

    Full Text Available The article highlights the benefits of adopting the practice of long-term planning with the aim of helping decision makers and politicians to include scenario thinking in the process of determining food security in Israel, 2050. This study addresses the question of food security, a step that is in contrast with agricultural planning considerations of the past that have mainly focused on maximizing profits or relied on a closed mathematical model. Two teams of experts identified production limitations affecting long-term planning and the ability to ensure food security under these conditions. It was found that there are five key factors important for the decision process: population, land, water, technology and international trade. The data show that today Israel imports a very large scale of virtual land and virtual water in terms of agricultural products. This means that the attention of the decision makers must be diverted from considerations of short-term profit to long-term food security.

  17. Web-based description of the space radiation environment using the Bethe-Bloch model

    Space weather is a rapidly growing area of research not only in scientific and engineering applications but also in physics education and in the interest of the public. We focus especially on space radiation and its impact on space exploration. The topic is highly interdisciplinary, bringing together fundamental concepts of nuclear physics with aspects of radiation protection and space science. We give a new approach to presenting the topic by developing a web-based application that combines some of the fundamental concepts from these two fields into a single tool that can be used in the context of advanced secondary or undergraduate university education. We present DREADCode, an outreach or teaching tool to rapidly assess the current conditions of the radiation field in space. DREADCode uses the available data feeds from a number of ongoing space missions (ACE, GOES-13, GOES-15) to produce a first order approximation of the radiation dose an astronaut would receive during a mission of exploration in deep space (i.e. far from the Earth’s shielding magnetic field and from the radiation belts). DREADCode is based on an easy-to-use GUI interface available online from the European Space Weather Portal (www.spaceweather.eu/dreadcode). The core of the radiation transport computation to produce the radiation dose from the observed fluence of radiation observed by the spacecraft fleet considered is based on a relatively simple approximation: the Bethe-Bloch equation. DREADCode also assumes a simplified geometry and material configuration for the shields used to compute the dose. The approach is approximate and sacrifices some important physics on the altar of rapid execution time, which allows a real-time operation scenario. There is no intention here to produce an operational tool for use in space science and engineering. Rather, we present an educational tool at undergraduate level that uses modern web-based and programming methods to learn some of the most important

  18. Excitonic effects in solids : time-dependent density functional theory versus the Bethe-Salpeter equation

    International Nuclear Information System (INIS)

    Sagmeister, S.

    2009-01-01

    The aim of this work is to compare two state-of-the-art methods for the investigation of excitonic effects in solids, namely Time-Dependent Density Functional Theory (TDDFT) and Many-Body Perturbation Theory (MBPT), for selected simple gap systems as well as semiconducting polymers. Within TDDFT, the linear response framework is used and the Dyson equation for the density-density response function is solved, whereas within MBPT, the Bethe-Salpeter equation (BSE) for the electron-hole correlation function is solved. The dielectric function is obtained as a last step. Both techniques take into account the excitonic effects caused by the interaction of electron-hole pairs. In the former these effects are included in the exchange-correlation (xc) kernel, whereas in the latter they are located in the interaction kernel of the BSE. Kohn-Sham single-particle wave functions obtained from Density Functional Theory within the linearized augmented planewave (LAPW) method are used to calculate all relevant quantities of the formalism. For the simple systems GaAs, Si and LiF are chosen. The role of several approximations to the xc kernel is studied and it is found that for GaAs and Si simple semi-empirical models provide a dielectric function in accordance with the BSE. For the case of LiF, being a system with a weak screening and a strongly bound exciton, only an xc kernel derived from MBPT yields reasonable results but still a slight discrepancy to the BSE is observed. Finally, the semiconducting polymers poly-acetylene and poly(phenylene-vinylene) (PPV) are studied. For both materials the concept of semi-empirical approximations to the xc kernel turns out to be ambiguous due to their low-dimensional character. In the case of poly-acetylene, the xc kernel derived from MBPT yields a dielectric function which is in close but not exact agreement with the one obtained from the BSE. (author) [de

    Gastric cancer is the fourth most common malignancy worldwide. The incidence trends and mortality rates of gastric cancer in Israel have not been studied in depth. The aim of our study was to try and investigate the aforementioned issues in Israel in different ethnic groups. This retrospective study is based on the data of The Israel National Cancer Registry and The Central Bureau of Statistics. Published data from these two institutes were collected, summarized, and analyzed in this study. Around 650 new cases of gastric cancer are diagnosed yearly in Israel. While we noticed a decline during the period 1990-2007 in the incidence in the Jewish population (13.6-8.9 and 6.75-5.42 cases per 100,000 in Jewish men and women, respectively), an increase in the Arab population was noticed (7.7-10.2 and 3.7-4.2 cases per 100,000 in men and women, respectively). Age-adjusted mortality rates per 10,000 cases of gastric cancer decreased significantly, from 7.21 in 1990 to 5.46 in 2007, in the total population. The 5-year relative survival showed a slight increase for both men and women. There is a difference in the incidence and outcome of gastric cancer between the Jewish and Arab populations in Israel. The grim prognosis of gastric cancer patients in Israel is probably due to the advanced stage at which gastric cancer is diagnosed in Israel.

  5. Quantum solitons and their classical relatives: Bethe Ansatz states in soliton sectors of the Sine--Gordon System

    International Nuclear Information System (INIS)

    Garbaczewski, P.

    1982-01-01

    Previously we have found that the semiclassical sine--Gordon/Thirring spectrum can be received in the absence of quantum solitons via the spin 1/2 approximation of the quantized sine--Gordon system on a lattice. Later on, we have recovered the Hilbert space of quantum soliton states for the sine--Gordon system. In the present paper we present a derivation of the Bethe Ansatz eigenstates for the generalized ice model in this soliton Hilbert space. We demonstrate that via ''Wick rotation'' of a fundamental parameter of the ice model one arrives at the Bethe Ansatz eigenstates of the quantum sine--Gordon system. The latter is a ''local transition matrix'' ancestor of the coventional sine--Gordon/Thirring model, as derived by Faddeev et al. within the quantum inverse-scattering method. Our result is essentially based on the N< infinity,Δ = 1,m<<1 regime. Consequently, the spectrum received, though resembling the semiclassical one, does not coincide with it at all

It participates in research, teaching and regulatory activities, and also provides laboratory services. To report data on the epidemiology of poisonings and poison exposures in Israel. We made computerized queries and descriptive analyses of the medical records database of the IPIC during 2012. A total of 31,519 poison exposure cases were recorded, a 157.6% increase compared with 1995. Children snake venom. Four fatalities were recorded; all were intentional exposures in adults (corrosive, medications, energy drink). Poison exposures and poisonings have increased significantly and have contributed substantially to morbidity and mortality in Israel. The IPIC database is a valuable national resource for the collection and monitoring of poisoning exposure cases. It can be used as a real-time surveillance system for the benefit of public health. It is recommended that reporting to the IPIC become mandatory and its activities be adequately supported by national resources.

  7. A Short Profile of Hypnotherapy Licensure in Israel.

    Binyaminy, Binyamin; Haas, Eric J

    2016-01-01

    In Israel, only physicians, dentists, and psychologists who complete an accredited licensing process may practice hypnosis. This study examines the characteristics of hypnotherapists compared to nonhypnotherapists in the same discipline. All hypnotherapists in Israel were compared to nonhypnotherapist health professionals. There are more subspecialists among hypnotists, and the most common specialties were psychiatry, pediatric dentistry, and clinical psychology. These findings imply self-sorting of hypnotists as a result of the regulation in Israel. Licensure of hypnotherapists could be useful in other countries by comprehensive follow-up of all licensed hypnotists and by improving public and health professional perceptions of the field and its relevance to clinical practice.

    Selecting the research efforts to be highlighted in the Israel Atomic Energy Commission's Annual Report from the large body and broad spectrum of ongoing work is not an easy task. The extensive bibliography of published results attached to the report attests to the scope of this difficulty.

    This paper presents the first experience gained in the use of the unique climate and spa of the Dead Sea for the treatment and rehabilitation of the Chernobyl liquidators at clinic near the city of Arad. Ninety-six patients were treated in Israel, in 40 of these radiation was the etiological factor of the disease: consequences of acute and chronic radiation disease, the astheno-neurotic syndrome, discirculatory encephalopathy, subatrophic laryngopharyngitis, and obstructive bronchitis. Eighty-eight patients had direct indications for treatment at the Dad Sea; locomotory, respiratory, and skin diseases. The course of treatment included the Dad Sea baths, mud applications, sun baths, climatotherapy, physiotherapy, massage, bioenergy therapy, inhalations, moisturizing creams, etc. An appreciable improvement with resolution of the principal symptoms was attained in 82% of patients, in 13% improvement with a significant abatement of the symptoms was achieved, whereas in 5% no apparent results were seen

    A committee of experts appointed by the Minister of Labour and Social Affairs has proposed a comprehensive draft regulation, concerning the legal aspects of occupational radiation protection in Israel. The first section of the proposed regulation sets forth guidelines for control in facilities where workers handle radioactive materials or radiation equipment. This includes the duties of the managers of such places to ensure adequate radiation protection and also the maximum recommended doses (whole body and individual organs) for radiation workers. The second section deals with the monitoring regulations for radiation workers who may be exposed to doses in excess of 500 mRem/y. The third section outlines the nature of the mechanical supervision required, i.e. routine and special examinations. Finally the committee also proposed six miscellaneous recommendations for radiation protection. (UK)

    Full-time work has long been perceived as a cornerstone of medical residency, the consensus being that a resident must apply the bulk of his time and attention to his professional training. Demographic and cultural changes that have taken place over the last several years, specifically the rise in the number of female doctors and the importance of leisure time to the younger generation, have intensified the need to find new and innovative ways to deal with the plight of the resident population. One idea, already in effect in many Western countries, is the institution of part-time residency programs. The possibility of fulfilling residency requirements on a part-time basis is intended to assist medical residents in integrating their professional development with their personal and family life, without compromising the quality of their training. A number of research studies conducted over the last several years in countries that allow part-time residency, among them the United States, England and Switzerland, aimed to examine the quality of part-time training. The various studies evinced a high level of satisfaction from the program both by the residents themselves and their supervisors, and in many aspects those doing residency part-time received higher appraisals than their full-time colleagues. Some of the residents polled noted that they would have totally foregone the practice of medicine had there not been an option to complete residency part-time. In light of the experience throughout the world and the changing landscape in Israel, the Scientific Council of the Israeli Medical Association decided to examine the issue and its various aspects, and weighed all the considerations in favor and against part-time residency. Recently, the Scientific Council approved the launch of a pilot program to allow part-time residency in several fields that were carefully selected according to specific criteria. Once the Ministry of Health completes the LegisLation process, part

    Large amounts of expired and unused medications accumulate in households. This potentially exposes the public to hazards due to uncontrolled use of medications. Most of the expired or unused medications that accumulate in households (household medical waste) is thrown to the garbage or flushed down to the sewage, potentially contaminating waste-water, water resources and even drinking water. There is evidence that pharmaceutical active ingredients reach the environment, including food, however the risk to public health from low level exposure to pharmaceuticals in the environment is currently unknown. In Israel, there is no legislation regarding household medical waste collection and disposal. Furthermore, only less than 14 % of Israelis return unused medications to Health Maintenance Organization (HMO) pharmacies. In this study, we investigated world-wide approaches and programs for household medical waste collection and disposal. In many countries around the world there are programs for household medical waste collection. In many countries there is legislation to address the issue of household medical waste, and this waste is collected in hospitals, clinics, law enforcement agencies and pharmacies. Furthermore, in many countries, medication producers and pharmacies pay for the collection and destruction of household medical waste, following the "polluter pays" principle. Several approaches and methods should be considered in Israel: (a) legislation and regulation to enable a variety of institutes to collect household medical waste (b) implementing the "polluter pays" principle and enforcing medical products manufactures to pay for the collection and destruction of household medical waste. (c) Raising awareness of patients, pharmacists, and other medical health providers regarding the health and environmental risks in accumulation of drugs and throwing them to the garbage, sink or toilet. (d) Adding specific instructions regarding disposal of the drug, in the

    1977-12-01

    The geology of Israel is relatively simple. Most of the country is underlain by sedimentary rocks of Secondary and Tertiary age. As far as the IAEA is aware no systematic exploration has been done for conventional type uranium deposits. Israel has no uranium deposits, and no high or low-grade uranium ores. However, there are uranium 'sources' which are mainly phosphate rock.Proven phosphate reserves in Israel are estimated at about 220 million tons in five different locations. The average uranium concentration is between 100 and 170 ppm. This makes the uranium content in the proven phosphate reserves of Israel to be about 25,000 tons. Together with the possibility of additional discoveries and on the assumption that the economic conditions for the production of both phosphate and uranium become favourable the Speculative Potential is placed in the 10,000 to 50,000 tonnes uranium category.

    2003-12-01

    Full Text Available The relationship between Israel and the United States has been evolving from that of an alliance during the Cold War to a symbiosis nowadays. American policy toward the Middle East is marked by its interest in oil, to which its growing relationship with Israelhas gradually been added. However, although for a long time the interests it shared with Saudi Arabia and other Arab countries moderated its policy and balanced its support of Israel somewhat, in the last few years its alliance with Israel has come to dominate Washington’s strategy. This is reflected in its invasion of Iraq and its tensions with Arab countries. The reason for this evolution must be sought, primarily, in the influence that Israel and pro-Zionist lobbies have gained in the domestic policy of the United States.

    Full Text Available Purpose. The State of Israel is one of the world leaders in the development of modern technologies, particularly in fisheries industry. E.g., 30 fish farms annually provide production of over 18,000 tons of fish, with an average yield of more than 8 tons per hectare. The fish equipment manufactured in this country is supplied to the Asia, Africa, Europe, South and North America countries, Australia. Israelis' specialists and companies design, build and implement engineering and technological support of fish-breeding enterprises in the EU, China, Nigeria, Georgia, Russia, Belarus, etc. The ongoing shortage of water in the country has spurred innovation in water conservation techniques, and a substantial agricultural modernization, drip irrigation. Israel is also at the technological forefront of desalination and water recycling. The Sorek desalination plant is the largest seawater reverse osmosis (SWRO desalination facility in the world. As of 2015, more than 50 percent of water for Israeli households, agriculture and industry is artificially produced. The country hosts an annual Water Technology and Environmental Control Exhibition & Conference (WATEC that attracts thousands of people from all over the world. In 2011, Israel's water technology industry was worth around $2 billion a year with annual exports of products and services of dozens of millions of dollars. Due to innovations in reverse osmosis technology, Israel is set to become a net exporter of water in the incoming years. At the same time, publications in Ukraine about the aquaculture branch of Israel concern mainly statistical information, or are devoted to individual ichthyopathological problems, genetic studies, etc. It does not allow analyzing a comprehensive development in this industry of Israel. Thus, the compilation and analysis of existing information is a relevant issue. This article expands the awareness of specialists on the specifics of fisheries industry, marine and

    2013-11-01

    Acanthamoeba keratitis (AK) is not a notifiable disease in Israel, so there are no accurate incidence rates for this condition in Israel. The aim of this study was to estimate the incidence of AK in Israel for the years 2008-2012. We distributed a survey questionnaire to laboratory managers in Israel. The laboratories were affiliated to medical institutes that either provided ophthalmology services or served community ophthalmology clinics. Our questionnaire requested survey respondents to provide information regarding the methods used to diagnose AK, and the number of positive and negative cultures for Acanthamoebae species performed for each of the years from 2008 to 2012. Six laboratories used non-nutrient agar with Escherichia coli as the culture medium, one used calcofluor-white staining with fluorescent microscopy, and two used PCR for diagnosing AK. Twenty-three AK cases were identified, to give an estimated incidence of 1/1 668 552. AK is mostly attributable to the use of contact lenses. As contact lenses are popular in Israel, we expected a higher incidence rate. A lower than expected incidence rate may indicate insufficient awareness of AK in Israel.

    Leptonic decay widths for pseudoscalar mesons are calculated in a QCD-motivated Bethe-Salpeter formalism on a two-tier basis. This model, which is characterised by a Lorentz-invariant confining kernel that depends on the relativistic reduced mass defined in accordance with the Wightman-Garding definition of the internal 4-momenta q μ , has already shown precision fits to the spectra of qq-bar, qQ-bar and qqq hadrons apart from exhibiting an eplicit Regge-asymptotic behaviour (M 2 ∼N). The leptonic decay constants thus obtained with no free parameters, are (in MeV units), f P =134(π), 166(K); 158(D); 94.9(B), 114(B S ). (author)

    2009-01-01

    We construct quantum integrable systems associated with non-skew-symmetric gl(2)-valued classical r-matrices. We find a new explicit multiparametric family of such the non-skew-symmetric classical r-matrices. We consider two classes of examples of the corresponding integrable systems, namely generalized Gaudin systems with and without an external magnetic field. In the case of arbitrary r-matrices diagonal in a standard gl(2)-basis, we calculate the spectrum of the corresponding quantum integrable systems using the algebraic Bethe ansatz. We apply these results to a construction of integrable fermionic models and obtain a wide class of integrable Bardeen-Cooper-Schrieffer (BCS)-type fermionic Hamiltonians containing the pairing and electrostatic interaction terms. We also consider special cases when the corresponding integrable Hamiltonians contain only pairing interaction term and are exact analogs of the 'reduced BCS Hamiltonian' of Richardson

    The magnetic properties of the ternary system ABC consisting of spins {sigma}=1/2 , S=1, and m=3/2 are investigated on the Bethe lattice by using the exact recursion relations. We consider both ferromagnetic and antiferromagnetic exchange interactions. The exact expressions for magnetizations and magnetic susceptibilities are found, and thermal behaviors of magnetizations and susceptibilities are studied. We construct the phase diagrams and find that the system exhibits one, two or even three compensation temperatures depending on the values of the interaction parameters in the Hamiltonian. Moreover, the system undergoes a second-order phase transition for the coordination number q{<=}3 and a second- and first-order phase transitions for q>3; hence the system gives a tricritical point. The system also exhibits the reentrant behaviors.

    Israel,where 100% of all energy sources are imported, and where more than 100% of the water potential is used, will have to rely in the future on nuclear power reactors and nuclear desalination. The total electric capacity of about 4,000 Mwe in 1985 will propably rise to about 8,000 Mwe in 1995 and to about 16,000 Mwe or more in 2005. It is likely that the 12,000 Mwe plants to be built and operated after 1985, will be largely nuclear, if possible, with maybe some capacity of alternate sources, now in development in the country, including hydro from a proposed Mediterranean-Dead Sea canal (about 400 m height difference), pumped storage, shale oil, solar ponds. In view of the acute water shortage in the country, it is likely that between one third and one half of the 12,0OO Mwe plants will have to be dual-purpose plants, for power production and water desalination. As a preparation for this stage, a 10 million gallon per day desalination unit, Israeli designed and built, the so-called Horizontal-Tube-Multi-Effect (H.T.M.E.) aluminum tube plant, will be attached to an existing 50 Mwe oil-fuelled turbine and scheduled to be in operation in 1981 at Ashdod on the Mediterranean Sea as a Joint Israel - U.S.A. project. Several identical 1O MGD modules will form in the future the desalination plant to be attached to nuclear dual-purpose reactors. Fuel fabrication, starting possibly with imported enriched UF 6 of nuclear fuel following the first LOAD, is contemplated to be made in the country. The desalination plants are intended to be 1O0% locally made. It is besides conceivable that the day will come when it will be nessary to connect the Red Sea and the Mediterranean by another canal, so that by the year 2000 and in the third millenium the two seas will be connected by two waterways -the Suez canal and the Israeli canal.

  9. Radiation Exposure to Concrete in Israel

    2014-01-01

    Most building materials of terrestrial origin contain small amounts of radionuclides of natural origin, mainly from the Uranium (238U) and Thorium (232Th) decay chains and the radioactive isotope of potassium, 40K. The external radiation exposure is caused by gamma emitting radionuclides, which in the uranium series mainly belong to the decay chain segment starting with Radium (226Ra). The internal (by inhalation) radiation exposure is due to Radon (222Rn), and its short lived decay products, exhaled from building materials into the room air. Due to economical and environmental reasons there is an increased tendency to use industrial by-products containing relatively high concentrations of radionuclides of natural origin in the building material industry. Fly ash (FA), produced as by-product in the combustion of coal, is extensively used in Israel since mid eighties of the last century in concrete and as an additive to cement . The increase of 226Ra activity concentration, the mineralogical characteristics of the FA and of the concrete may influence on the radon exhalation rate and consequently on the radon exposure of the public. The recently published Israeli Standard 5098 (IS 5098) 'Content of natural radioactive elements in building products' limits the content of natural radionuclides as well as the radon emanation from concrete. This paper presents a compilation of three studies conducted at Soreq Nuclear Research Centre (SNRC), Technion, NRG and Environmental Lab BGU (ELBGU) to investigate and quantify the influence of FA addition in concrete

  10. Spring Bird Migration Phenology in Eilat, Israel

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available Analysis of the mean date of first captures and median arrival dates of spring migration for 34 species of birds at Eilat, Israel, revealed that the earlier a species migrates through Eilat, the greater is the inter-annual variation in the total time of its passage. Birds arrive during spring migration in Eilat in four structured and independent waves. The annual fluctuation in the initial arrival dates (initial capture dates and median dates (median date of all captures, not including recaptures, did not depend on the length of the migratory route. This implies that migrants crossing the Sahara desert depart from their winter quarters on different Julian days in different years. We suggest that negative correlations between the median date of the spring migration of early and late migrants depends upon the easterly (Hamsin wind period. Moreover, we believe that the phenology of all birds during spring migration in Eilat is possibly also determined by external factors such as weather conditions on the African continent or global climatic processes in the Northern hemisphere. Orphean Warblers (Sylvia hortensis show a strong positive correlation (rs=-0.502 of initial capture date with calendar years, whereas other species such as Barred Warbler (S. nisoria; rs = -0.391 and Spotted Flycatcher (Muscicapa striata; rs = -0.398 display an insignificant trend. The Dead Sea Sparrow (Passer moabiticus and Red-Backed Shrike (Lanius collurio are positively correlated regarding initial arrival date and medians of spring migration.

    Full Text Available This article discusses Zangwill’s Spitalfields, a mobile app with content curated, written, and produced by Nadia Valman, Soda Ltd (developer and the Jewish Museum, London (archive collaborator. The app uses Israel Zangwill’s novel 'Children of the Ghetto' (1892 as a walking guide to the Jewish immigrant subculture of Victorian Spitalfields, east London, which the novel describes at a moment of critical change. Zangwill’s Spitalfields exploits the app’s potential for bringing together a range of digital sources including archive photographs, museum objects, and oral history recordings with the user’s observations of the physical environment, to produce an experience that is both immersive and multivocal. Mobile digital technology has provided a new interpretive context for the Jewish Museum’s collection, and animated previously unmarked monuments in Spitalfields. By drawing on the user’s experience of walking in present-day Spitalfields, the app also intervenes into a historiography increasingly shaped by nostalgia.

  12. Fertility behaviour of recent immigrants to Israel

    Directory of Open Access Journals (Sweden)

    2004-03-01

    Full Text Available The fertility practices of immigrants are a particularly interesting field of study for demographers, providing an insight into the fertility behaviour of individuals when both the society and the individual undergo a period of rapid change. This paper describes and compares the fertility behaviour of two large groups of immigrants, from the former Soviet Union (FSU and from Ethiopia to Israel in the last 20 years. The changes in fertility behaviour undergone in the same society and at the same time by two very different groups are examined. The findings reveal that the fertility behaviour of immigrants is indeed changing. The fertility of FSU immigrants is increasing and that of the Ethiopian immigrants decreasing, with accompanying changes in the proximate determinants of fertility. Although the fertility of immigrants is becoming more similar to that of the receiving society, the methods employed to achieve the fertility change are not necessarily similar, and, in some cases, diverge from the norms of the receiving society.

    2011-01-01

    Albert Einstein was initially skeptical and even disdainful of the Zionist movement, yet he affiliated himself with this controversial political ideology and today is widely seen as an outspoken advocate for a modern Jewish homeland in Palestine. What enticed this renowned scientist and humanitarian, who repeatedly condemned nationalism of all forms, to radically change his views? Was he in fact a Zionist? Einstein Before Israel traces Einstein's involvement with Zionism from his initial contacts with the movement at the end of World War I to his emigration from Germany in 1933 in the wake of Hitler's rise to power. Drawing on a wealth of rare archival evidence--much of it never before published--this book offers the most nuanced picture yet of Einstein's complex and sometimes stormy relationship with Jewish nationalism. Ze'ev Rosenkranz sheds new light on Einstein's encounters with prominent Zionist leaders, and reveals exactly what Einstein did and didn't like about Zionist beliefs, objectives, and methods...

    Beth Israel Deaconess Medical Center (BIDMC), an academic health care institution affiliated with Harvard University, has been an early adopter of electronic applications since the 1970s. Various departments of the medical center and the physician practice groups affiliated with it have implemented electronic health records, filmless imaging, and networked medical devices to such an extent that data storage at BIDMC now amounts to three petabytes and continues to grow at a rate of 25 percent a year. Initially, the greatest technical challenge was the cost and complexity of data storage. However, today the major focus is on transforming raw data into information, knowledge, and wisdom. This article discusses the data growth, increasing importance of analytics, and changing user requirements that have shaped the management of big data at BIDMC.

    To compare functional and anatomical outcomes after idiopathic epiretinal membrane (ERM) peeling combined with phacoemulsification and intraocular lens implantation versus ERM peeling alone. A retrospective, non-randomised comparative case series study was conducted of 81 eyes from 79 patients who underwent ERM peeling at the Beth Israel Deaconess Medical Center between 2001 and 2010. Eyes that underwent combined surgery for ERM and cataracts (group 1) were compared with those that had ERM peeling alone (group 2) with respect to best-corrected visual acuity at 6 months and 1 year after surgery, postoperative central macular thickness (CMT) as measured on optical coherence tomography, and rates of complications, including elevated intraocular pressure (IOP), ERM recurrence and need for reoperation. Mean logMAR visual acuity improved significantly in both groups at 6 months (ppeeling alone with respect to visual and anatomical outcomes. Further studies are necessary to determine if there may be greater ERM recurrence or need for reoperation after combined surgery.

  17. Erico Verissimo: um “pintor” brasileiro de Israel

    2010-03-01

    Full Text Available O escritor brasileiro Erico Verissimo viajou a Israel em abril de 1966, na companhia da esposa, a convite do Ministério de Negócios Estrangeiros daquele país. As anotações feitas por Verissimo durante o percurso pelas principais cidades israelenses foram transformadas no livro Israel em abril, escrito e publicado três anos após a viagem. Juntamente com os manuscritos da obra, o escritor enviou ao seu editor uma carta, na qual afirma que sua intenção ao iniciar o livro “era ‘pintar’ Israel com a despreocupada alegria lúdica dum artista em férias”. Entretanto, no decorrer do trabalho, ao perceber que começava a fazer “perguntas perigosas” como “Que são os judeus? Uma raça? Um povo? Um conjunto de tribos unidas por uma religião comum?”, Verissimo deixou que o bom senso prevalecesse e voltou à sua “pintura”. Pretende-­se, neste artigo, analisar a obra Israel em abril, verificando em que medida o olhar despreocupado do pintor se confunde com o olhar crítico do intelectual no relato de suas impressões em Israel.

    Immigration from Ethiopia to Israel started about 30 years ago. We aimed to compare birth outcomes between Israeli women of Ethiopian origin and Israeli-born, non-Ethiopian women. We hypothesized a higher frequency of adverse birth outcomes among Ethiopian women and a trend of improvement among those who were raised in Israel since early childhood. This is a descriptive study, comparing birth outcomes of Ethiopian (n = 1,319) and non-Ethiopian women (n = 27,307) who gave birth in a medical center in Central Israel in 2002 to 2009. Ethiopian women were further categorized by age at immigration. Logistic regressions were constructed to compare the incidence of adverse birth outcomes between Ethiopian and non-Ethiopian women, controlling for potential confounders. Ethiopian women had about twice the incidence of very and extremely preterm births, compared with non-Ethiopians. Ethiopian women had twice the odds for neonates who were either small for gestational age or had low 5-minute Apgar scores. Ethiopian women had about threefold increased risk of stillbirths (OR 2.9 [95% CI 1.87-4.49]). No trend of improvement was noted for women who were raised in Israel from early childhood. Ethiopian women are at increased risk of adverse birth outcomes. Future research is needed to investigate the underlying causes for the increased risks and lack of improvement among those who were raised in Israel that will lead to effective interventions. © 2015 Wiley Periodicals, Inc.

    The role of human papillomavirus (HPV) infection in oropharyngeal cancer (SCC) is well established. The annual incidence of oropharyngeal SCC in Israel is considerably lower than that in the United States. The purpose of this study was to assess the rate of HPV-related oropharyngeal SCC in Israel. The cohort included patients with oropharyngeal SCC who were treated during 1999 to 2011 in Israel. HPV typing was carried out using reverse hybridization and immunohistochemistry. Of the 74 patients analyzed, 25 (33.7%) had detectable HPV DNA. Patients in the HPV-positive group tended to be younger, with a higher rate of nodal metastases, and no history of smoking (p Israel as approximately 3-fold lower than in Western countries. Low exposure to HPV-16, a lower rate of transformation, to cancer or protective genetic factors may contribute to the lower rate of oropharyngeal SCC in Israel. © 2015 Wiley Periodicals, Inc.

  20. Management of saline soils in Israel

    International Nuclear Information System (INIS)

    Rawitz, E.

    1983-01-01

    The main soil salinity problem in Israel is the danger of gradual salinization as a result of excessively efficient water management. Aquifer management is aimed at preventing flow of groundwater into the ocean, causing a creeping salinization at a rate of about 2 ppm per year. Successful efforts to improve irrigation efficiency brought with them the danger of salt accumulation in the soil. A ten-year monitoring programme carried out by the Irrigation Extension Service at 250 sampling sites showed that appreciable salt accumulation indeed occurred during the rainless irrigation season. However, where annual rainfall is more than about 350 mm this salt accumulation is adequately leached out of the root zone by the winter rains. Soil salinity in the autumn is typically two to three times that in the spring, a level which does not affect yields adversely. In the drier regions of the country long-term increasing soil salinity has been observed, and leaching is required. This is generally accomplished during the pre-irrigation given in the spring, whose size is determined by the rainfall amount of the preceding winter. The increasing need to utilize brackish groundwater and recycled sewage effluent requires special measures, which have so far been successful. In particular, drip irrigation with its high average soil-water potential regime and partial wetting of the soil volume has achieved high yields under adverse conditions. However, the long-term trend of water-quality deterioration is unavoidable under present conditions, and will eventually necessitate either major changes in agricultural patterns or the provision of desalinated water for dilution of the irrigation water.

  1. Israel and Iran's Nuclear Program: Groundless Obsession or Genuine Concern?

    International Nuclear Information System (INIS)

    Menashri, David

    2008-01-01

    The combination of radical ideology, as espoused by Iran's leadership, and weapons of mass destruction (WMD) is the root cause of Israeli concerns. Iran's attitude towards Israel seems to be rooted in a deep sense of religious mission, identification with the Palestinian problem, opposition to Israel and to its policies. For Islamic Iran, Judaism is a religion, not a nationality, and therefore Jews do not have the right to a state, certainly not in the Middle East. Moreover Iran supports Islamic groups as Hezbollah and Hamas. In this context Israel should view the Iranian nuclear program as the problem of the world, but the international community is not doing what it is supposed to do to solve the problem

  2. Gun utopias? Firearm access and ownership in Israel and Switzerland.

    Rosenbaum, Janet E

    2012-02-01

    The 2011 attempted assassination of a US representative renewed the national gun control debate. Gun advocates claim mass-casualty events are mitigated and deterred with three policies: (a) permissive gun laws, (b) widespread gun ownership, (c) and encouragement of armed civilians who can intercept shooters. They cite Switzerland and Israel as exemplars. We evaluate these claims with analysis of International Crime Victimization Survey (ICVS) data and translation of laws and original source material. Swiss and Israeli laws limit firearm ownership and require permit renewal one to four times annually. ICVS analysis finds the United States has more firearms per capita and per household than either country. Switzerland and Israel curtail off-duty soldiers' firearm access to prevent firearm deaths. Suicide among soldiers decreased by 40 per cent after the Israeli army's 2006 reforms. Compared with the United States, Switzerland and Israel have lower gun ownership and stricter gun laws, and their policies discourage personal gun ownership.

  3. Medicine Among New Immigrants and Arab Minorities in Israel

    The reaction to modern medicine and the general health of the new immigrants and Arab populations of Israel are described. The material was gathered during a threemonth visit to Israel where the author participated in the medical care of these persons. While these peoples still share many of the traditional medical superstitions and practices, the new immigrants have progressed much more during the 16 years of Israel's existence. At present over 99% of Jewish women give birth in hospital, whereas only 65% of Israeli Arabs do. The infant mortality rate among the Jews in 1963 was about 21 deaths per 1000 live births, about one-half the rate for Arabs. The importance of understanding the cultural background and social conflicts of these people as a preliminary to the provision of proper medical care is stressed.

    2016-06-01

    Full Text Available Israel is known as a pronatalist country. Whether due to the Biblical commandment to ‘be fruitful and multiply’ or the traumas of the Holocaust and perennial wars, reproduction is a central life goal for most Israelis. Israeli women bear substantially more children than their counterparts in industrialized countries and view child-rearing as a key life accomplishment. These personal world-view and real-life individual quests take place in a context of equally pronatalist state policies and religious openness to assisted reproductive technologies. In this paper, I outline 35 years of assisted reproductive technologies in Israel by tracing a principal axis in the development of three major technologies of assisted reproduction: the proliferation of IVF-ICSI; the globalization of gamete donation; and the privatization of surrogacy. The paper is based on a policy analysis as well as various studies of assisted reproductive technologies, conducted in Israel over this period.

    A preliminary work aimed at allocating suitable new sites for possible NPPs in Israel is presented. The work is based on Israel's present NPP siting criteria, supported by selected procedure performed by various countries that conducted similar process. The site selection process was conducted in two stages: first, a selection procedure using demographic analysis was conducted; second, a seismological and geological analysis process was performed in the remaining area. From the combined two screening processes results, an overall new area of 569 km{sup 2} was located as a possible area for future construction of NPPs in Israel. Further and more comprehensive work, based on the IAEAs site selection guidelines, has to be performed in the future, in order to verify the preliminary findings presented in this work.

  6. Palestine, Israel and the Geopolitics of Western Asia

    2018-05-01

    Full Text Available The efforts of the international community in providing a solution to the Israeli-Palestinian conflict are still colliding with the demonstrations of force of the Government of Israel and its insistence on bilateral negotiation. Here it is argued that the understanding of the problem merits a review of the geopolitical game in Western Asia, where the major powers set up alliances and unleashed wars in their own interest. Since the United State-Israel Alliance remains unshakable in the region, the will of the international community to commit the United States to an end to confrontation through the multilateral recognition of the Palestinian State should be maintained without hesitation, since the alternative of a bilateral agreement with Israel does not offer more to Palestine than surrender.

    1999-01-01

    We conducted a retrospective serosurvey of 1,000 persons in Israel who had fever of undetermined cause to look for Ehrlichia chaffeensis antibodies. Four of five cases with antibodies reactive to E. chaffeensis were diagnosed in the summer, when ticks are more active. All patients had influenzalike symptoms with high fever. None of the cases was fatal. Three serum samples were also seroreactive for antibodies to E. canis, and one was also reactive to the human granulocytic ehrlichiosis (HGE) agent. The titer to the HGE agent in this patient was higher than the serum titer to E. chaffeensis, and the Western blot analysis also indicated that the HGE agent was the primary cause of infection. We present the first serologic evidence that the agents of human monocytic ehrlichiosis (HME) and HGE are present in Israel. Therefore, human ehrlichiosis should be included in the differential diagnoses for persons in Israel who have been exposed to ticks and have influenzalike symptoms. PMID:10603210

    2015-08-01

    In recent years Israel has become a destination for many migrants from Africa that illegally cross the Egyptian-Israeli border. The objective of this paper is to describe the epidemiological characteristics of injuries among illegal migrants in Israel. The study was carried out retrospectively using data from 19 trauma centers that participated in the Israel National Trauma Registry between 1 January 2006 and 31 December 2011. Illegal migrants from Africa were compared to the local population. Migrants were injured more often than the local population from intentional injuries (57.11 %). Migrants were also less likely than the local population (58.38 %) to sustain a minor injury (i.e., injury severity ≤8). The study also shows the hospitalization cost as a result of injuries among migrants from Africa. Preventive measures among illegal migrants from Africa should prioritize intentional injuries and industrial site injuries.

  9. Fertility and marriage behavior in Israel: Diversity, change, and stability

    2013-03-01

    Full Text Available BACKGROUND Based on aggregate statistics, the population of Israel, as compared to all or most other developed societies, has very high levels of fertility and marriage (e.g. TFR of 2.96 in 2009 and only 9.7Š never married among women aged 40-44 in 2009. However, studying aggregate demographic measures is problematic, because Israel is an extremely heterogeneous society, with family formation patterns differing greatly across numerically important social groups. Until now, little has been documented about the basic fertility and marriage behavior of different population groups. OBJECTIVE We describe the fertility and marriage behavior of populations in Israel, broken down by nationality, religion, religiosity and nativity-status. Although our main focus is on a detailed presentation of fertility patterns, we also look at marriage behavior, as it is closely related to fertility in Israel. METHODS We analyze recently available annual data from the Israel Social Surveys for 2002-2009, which, for the first time in several decades,, provides detailed information on family and household demographic behavior and direct information on level of religiosity. We focus primarily on comparisons across cohorts born from the late 1940s to the late 1960s and between periods in the early and late 2000s. RESULTS We provide a detailed portrait of striking diversity in fertility and marriage behavior across population groups, along with important patterns of change and stability across cohorts and over time. We document findings and differential patterns, some unexpected, regarding comparisons across groups and across cohorts. CONCLUSIONS The descriptive findings form the basis for a clearer understanding of fertility and marriage patterns in different population subgroups in Israel. In addition, the reported results suggest many questions for future research, which are outlined in the paper.

    1997-11-01

    The energy production, in Israel, is not sufficient to satisfy the country needs, that is perpetually growing. Today 96% of the energy consumption is imported, essentially with petroleum and coal. To reduce this energy dependence, the government encourages the scientific researches and innovations in the field of clean and renewable energies. The paper presents political and economical aspects of the management and the exploitation of the following energy resources, developed in Israel: fossil fuels with oil shales; solar energy; biomass; wind energy; geothermal energy and hydraulic energy.

    "Using our mathematical model of a general theory of normative regulation, we have reproduced over 80% of the variance in the cumulative percentages of emigrants [from Israel], as well as the yearly percentages from 1950 to 1981. These results suggest that, except for a limited period following the 'Six-Day War' of 1967, no situation-specific explanations are needed to account for the trends in emigration from Israel, and the phenomenon can be adequately accounted for by the general theory of normative regulation in modern industrialized societies. Some practical conclusions to mitigate the process are drawn from these findings." excerpt

    This paper reports the characteristics of suicides which occurred during the existential and the non-existential wars in Israel. It provides a first approximation of whether the suicide patterns in each war are consistent with the findings of Morselli and Durkheim, and whether their theoretical interpretations can serve as a preliminary guideline to explaining the Israeli case, which is characterized by short periods of war, social integration during some of the non-existential wars, and a sharp rise in post-war male suicide rates following all of the existential wars. Implications for further studies on the subject in Israel and elsewhere are discussed.

    Recent results obtained by the application of the Bethe-Salpeter approach to the analysis of elastic electron-deuteron scattering with the separable NN kernel are presented. We analyze the impact of the P waves (negative-energy components) on the electromagnetic properties of the deuteron and compare it with experimental data. It was shown that the contribution of the P waves must be taken into account to explain tensor polarization and charge form factor of the deuteron

    2016-03-07

    We present a range-separated linear-response time-dependent density-functional theory (TDDFT) which combines a density-functional approximation for the short-range response kernel and a frequency-dependent second-order Bethe-Salpeter approximation for the long-range response kernel. This approach goes beyond the adiabatic approximation usually used in linear-response TDDFT and aims at improving the accuracy of calculations of electronic excitation energies of molecular systems. A detailed derivation of the frequency-dependent second-order Bethe-Salpeter correlation kernel is given using many-body Green-function theory. Preliminary tests of this range-separated TDDFT method are presented for the calculation of excitation energies of the He and Be atoms and small molecules (H{sub 2}, N{sub 2}, CO{sub 2}, H{sub 2}CO, and C{sub 2}H{sub 4}). The results suggest that the addition of the long-range second-order Bethe-Salpeter correlation kernel overall slightly improves the excitation energies.

  12. The Modern Anti-Semitism Israel Model: An empirical relationship between modern anti-Semitism and opposition to Israel

    2011-04-01

    Full Text Available The current paper reviews our program of research that has examined some of the causes and consequences of anti-Semitism in which a new theoretical model of anti-Semitism is presented and tested in six experiments. The model proposes that mortality salience increases anti-Semitism and that anti-Semitism often manifests as hostility towards Israel. In accord with predictions, results show that existential fears lead to higher anti-Semitism and reduced support for Israel. Collectively, these results may serve as a preliminary contribution to explaining the continuation of anti-Semitism.

  13. Moments of the Bethe surface and total inelastic x-ray scattering cross sections for H2

    Moments, S(j,K), of the generalized oscillator strength distribution are global properties of the Bethe surface. Apart from S(-1,K) which is related to the Waller-Hartree incoherent scattering factor, little is known about these moments for nonzero K. This paper describes high-accuracy calculations of S(1,K) and S(2,K) for molecular hydrogen. Comparison with experiment is made, and the utility of simple asymptotic approximations is confirmed. The moments are used to calculate differential cross sections for the inelastic scattering of x rays using the constant-momentum-transfer and constant-angle theories of Bonham. These cross sections differ from the Waller-Hartree cross sections at large angles thus demonstrating the importance of making corrections to the Waller-Hartree theory if the incoherent scattering factor S(K) is to be extracted from experimental inelastic cross sections. Total cross sections for scattering of 6- and 7-keV photons from H 2 are compared with synchrotron radiation scattering experiments. The calculations suggest that the Bonham constant-angle cross sections agree best with experiment. However, further experimental and theoretical work is needed to obtain firm conclusions about the limitations of Waller-Hartree theory

  14. The average kinetic energy of the heavy quark in Λb in the Bethe-Salpeter equation approach

    International Nuclear Information System (INIS)

    Guo, X.-H.; Wu, H.-K.

    2007-01-01

    In the previous paper, based on the SU(2) f xSU(2) s heavy quark symmetries of the QCD Lagrangian in the heavy quark limit, the Bethe-Salpeter equation for the heavy baryon Λ b was established with the picture that Λ b is composed of a heavy quark and a scalar light diquark. In the present work, we apply this model to calculate μ π 2 for Λ b , the average kinetic energy of the heavy quark inside Λ b . This quantity is particularly interesting since it can be measured in experiments and since it contributes to the inclusive semileptonic decays of Λ b when contributions from higher order terms in 1/M b expansions are taken into account and consequently influences the determination of the Cabibbo-Kobayashi-Maskawa matrix elements V ub and V cb . We find that μ π 2 for Λ b is 0.25GeV 2 ∼0.95GeV 2 , depending on the parameters in the model including the light diquark mass and the interaction strength between the heavy quark and the light diquark in the kernel of the BS equation. We also find that this result is consistent with the value of μ π 2 for Λ b which is derived from the experimental value of μ π 2 for the B meson with the aid of the heavy quark effective theory

    Full Text Available The article presents the analysis carried out by Ph. D. Beth Ann Beschorner (University of Iowa, USA which concerns the training program for parents aimed at teaching them how to arrange the Dialogic reading with their childrenand and which makes it possible to conclude that due to the experience and direct contact with the written language in preschool age the idea of literacy was being formed. The article compares the empirical data obtained independently in different areas of scientific knowledge, i.e., philosophy and psychology: the study of B.A. Beschorner has a lot in common with the principles of cultural-historical psychology, formulated by L. Vygotsky, M. Lisina and other national psychologists. Although B. A. Beschorner do not stick directly to cultural-historical and activity theory, her results correspond with the basic provisions of these theories. The analysis of B.A. Beschorner’s works confirms the commonality of her findings to those obtained in terms of the cultural-historical theory. It proves that scientific thoughts even going in independent ways, may lead to similar results, which ultimately demonstrates the validity of the findings and the versatility of approaches to the problem

  16. Part I: quantum fluctuations in chains of Josephson junctions. Part II: directed aggregation on the Bethe lattice

    International Nuclear Information System (INIS)

    Bradley, R.M.

    1985-01-01

    Part I studies the effect of quantum fluctuations of the phase on the low temperature behavior of two models of Josephson junction chains with Coulomb interactions taken into account. The first model, which represents a chain of junctions close to a ground plane, is the Hamiltonian version of the two-dimensional XY model in one space and one time dimension. In the second model, the charging energy for a single junction in the chain is just the parallel-plate capacitor energy. It is shown that quantum fluctuations produce exponential decay of the order parameter correlation junction for any finite value of the junction capacitance. Part II deals with two types of directed aggregation on the Bethe lattice - directed diffusion-limited aggregation DDLA and ballistic aggregation (BA). In the DDLA problem on finite lattices, an exact nonlinear recursion relation is constructed for the probability distribution of the density. The mean density tends to zero as the lattice size is taken into infinity. Using a mapping between the model with perfect adhesion on contact and another model with a particular value of the adhesion probability, it is shown that the adhesion probability is irrelevant over an interval of values

    2017-09-15

    We investigate the light-quarkonium spectrum using a covariant Dyson-Schwinger-Bethe-Salpeter-equation approach to QCD. We discuss splittings among as well as orbital angular momentum properties of various states in detail and analyze common features of mass splittings with regard to properties of the effective interaction. In particular, we predict the mass of anti ss exotic 1{sup -+} states, and identify orbital angular momentum content in the excitations of the ρ meson. Comparing our covariant model results, the ρ and its second excitation being predominantly S-wave, the first excitation being predominantly D-wave, to corresponding conflicting lattice-QCD studies, we investigate the pion-mass dependence of the orbital-angular-momentum assignment and find a crossing at a scale of m{sub π} ∝ 1.4 GeV. If this crossing turns out to be a feature of the spectrum generated by lattice-QCD studies as well, it may reconcile the different results, since they have been obtained at different values of m{sub π}.

    2013-07-01

    Full Text Available This paper discusses the history, organization, networks and political outlook of the state of Israel’s first conscientious objectors (COs in the 1950s, and the consequences they confronted, individually and as a group. Despite it being a very unlikely period for the foundation of such a movement, a small branch of ‘War Resisters’ International’ (WRI, 1921 was established in Israel in 1947. This paper discusses what can the attitudes towards COs tell of the early history of the State of Israel, especially at a time when conscientious objection was not recognized as a right almost anywhere. The history of the first Israeli COs breaks a number of assumptions, albeit contradictory ones: on the one hand it strengthens the image of Israel as a militaristic country; on the other, it shows that institutions were in Israel more tolerant towards COs than other countries; it shows that COs were the supporters of an non ethnically homogenous society and, most of all, that, even in a decade such as the 1950s, a different and deep voice was trying to make itself heard. This paper is based on primary sources from the WRI archives and on the correspondence that Israeli COs entertained with WRI in the 1950s.

    Full Text Available Este artículo es una contribución al conocimiento de las migraciones nacidas de la desintegración del bloque comunista. Desde 1989, más de 650.000 judíos han marchado de la ex-Unión Soviética para ir a Israel. Así, ese Estado se convierte en uno de los países del mundo que sufrió más intensamente los efectos de ese acontecimiento geográfico de mayor importancia. En esta contribución intentamos presentar, a través de algunos resultados de nuestro trabajo, las características de esta migración y contestar a las preguntas inherentes a tales problemáticas: ¿cómo Israel gestiona esa migración?, ¿cúales son sus efectos sobre un espacio tan atormentado y debatido?… Insistiremos también sobre los lazos establecidos entre Israel y la ex-URSS con la ayuda de las redes de migrantes. En conclusión, intentaremos situar ese movimiento en el nuevo contexto de migraciones en el cual vemos la integración progresiva de Israel en el sistema migratorio europeo con la entrada de trabajadores extranjeros y la presencia de una población en situación ilegal.

    Full Text Available Rhodococcus equi is a common cause of pneumonia in foals and has extensive clinical, economic and possibly zoonotic consequences. This bacterium survives well in the environment and may be considered as normal flora of adult horses. Certain strains of this bacterium are extremely virulent in foals, and early identification and intervention is crucial for prognosis. Rhodococcus equi is endemic in many parts of the world and occasionally isolated in Israel. This study was designed to evaluate R. equi seroprevalence in adult horses in Israel to indirectly indicate the potential level of exposure of susceptible foals. Sera were collected from 144 horses during spring 2011 and from 293 horses during fall 2014, and the presence of antibodies against virulent R. equi was detected by enzyme-linked immunosorbent assay. Equine seroprevalence of R. equi was found to be 7.6% in 2011 and 5.1% in 2014. Only one farm had seropositive horses in 2011, whereas several farms had seropositive horses in 2014. No significant risk factors for seropositivity were found. Rhodococcus equi appears to be endemic in Israel. This is the first survey of R. equi in Israel that provides information on the epidemiology of this important bacterium.

At the beginning Palestine was a part of Daulah Islamiyah under the Turki Usmani, but because this area was dominated by England in 1917, then about 48 percent of it was annexed by Jews, Palestine with the Muslim majority became not independent. This writing aims at exploring the struggle Muslim-Palestine toward Jews-Israel. For this purpose, the use of historical analysis and library research approaches in collecting data were used. The findings from this research are that Zionist Israel dominated Palestine because of being supported by its main allies: America, English and France while Palestine struggle alone because the surrounding Islamic countries had ever wanted to help in 1968 but they were lost in a six-day war. Therefore, Egypt, Syria and Jordan and Palestine released a part of their area. Lately Palestine becomes worse and if the Jews constitution proposed by Benyamin Netayahu to the Israel Parliament, Palestine and Arab Islam will be strongly insisted.

    2018-06-01

    Regulation is a key tool for implementing municipal solid waste (MSW) management strategies and plans. While local authorities in Israel are responsible for the storage, collection, and disposal of MSW, Israel's Ministry of Environmental Protection (MoEP) is responsible for the formulation and implementation of waste management policies and legislation. For the past 12 years, about 80% of the MSW in Israel has been landfilled and recycling rates have not increased, despite regulations. This paper presents the state of MSW management in Israel in light of the MoEP's strategic goal of landfilling reduction, the regulations and legislation designed and implemented for achieving this goal, and the ensuing results. Among other things, the results indicate the importance of monitoring and assessing policy and regulations to examine whether regulation is in fact effective and whether it keeps track of its own targets and goals or not. It is also concluded that even when there is an extensive regulation that includes a wide range of laws, economic penalties and financial incentives (such as landfill levy and financing of MSW separation at source arrangements), this does not guarantee proper treatment or even an improvement in waste management. The key to success is first and foremost a suitable infrastructure that will enable achievement of the desired results.

  9. The Second Demographic Transition in Israel: One for All?

    Directory of Open Access Journals (Sweden)

    Evgenia Bystrov

    2012-08-01

    Full Text Available This article explores family behaviours and attitudes in Israel over the last decades through the lens of the Second Demographic Transition (SDT. Israel is divided by religious affiliation, the level of religiosity, ethnic origin and timing of immigration. Although fertility transition to replacement level among certain societal groups has been previously shown, the question of how the transition unfolds in other domains remains open. The goal of this paper is to highlight the diversity of marital and fertility transitions and non-transitions among various groups of this heterogeneous society, and to compare Israel's transitions to European ones. The data sources which are used are cross-national large scale surveys, national representative surveys, and Population Register data. The data were disaggregated by religion, religiousness and ethnic origin. Emancipative value change, postponement of marriage, alternative living arrangements and a growing variety of fertility regimes were analyzed. A full range of pre-transitional, transitional, and post-transitional elements was found among the groups. Such sign of the SDT as growing childlessness was not found, and the spread of other features as unmarried cohabitation and non-marital childbearing was found limited. Population composition effects were isolated. It was found that the level of religiosity and the country of origin are important factors which differentiate family behaviours and attitudes. The connection between value orientation of the groups within Israel and their family behaviours is discussed. The socio-structural and institutional constraints that might impede further progression of the Second Demographic Transition in Israel are also discussed. Further research directions are suggested.

    Full Text Available This paper compares the framing of the coverage of judicial appointments in Israel in 2008 in two newspapers with nomination news from preceding years and to the patterns of press coverage in the U.S. A content analysis of 101 Supreme Court nomination articles indicated that unlike the political frame of American coverage, the press in Israel preserves its ostensible commitment to the professionalism of judges while linking the Supreme Court to political maneuvering in the selection of candidates. These findings are discussed within the context of the media's role in constructing judicial nominations as a debate about the role of the Supreme Court in Israeli society. Este artículo compara el marco de la cobertura de los nombramientos judiciales en Israel en 2008 en dos periódicos, con noticias de nombramientos de años anteriores y en los Estados Unidos, con los patrones de cobertura de prensa en los EE.UU. Un análisis de contenido de 101 artículos de nombramientos de la Corte Suprema indicó que, a diferencia del marco político de la cobertura de América, la prensa en Israel consierva su aparente compromiso con la profesionalidad de los jueces, a pesar de que relaciona la Corte Suprema con maniobras políticas en la selección de candidatos. Estos resultados se discuten en el contexto del papel de los medios de comunicación en la construcción de los nombramientos judiciales como un debate sobre el papel de la Corte Suprema en la sociedad israelí.

    West Nile virus (WNV) epidemiological situation in Israel and Palestine, due to their unique location, draws attention following to the global spread of West Nile fever (WNF). Although much information is available from Israel on clinical cases and prevalence of WNV, clinical cases are rarely reported in Palestine, and prevalence is not known. The objectives of this study were to determine WNV seroprevalence in various domestic animals in Palestine and to reevaluate current seroprevalence, force of infection, and risk factors for WNV exposure in horses in Israel. Sera samples were collected from 717 animals from Palestine and Israel (460 horses, 124 donkeys, 3 mules, 50 goats, 45 sheep, and 35 camels). Two hundred and ten horses were sampled twice. The level of WNV antibodies was determined using commercial Enzyme-linked Immunosorbent Assay (ELISA) Kit. Seroprevalence in equids was 73%. Seroprevalence in Israel (84.6%) was significantly higher than in Palestine (48.6%). Seroprevalence in horses (82.6%) was significantly higher than in donkeys and mules (39.3%). Multivariable statistical analysis showed that geographical area, landscape features (altitude), environmental factors (land surface temperature during the day [LSTD]), species, and age significantly influenced WNV seroprevalence. Fourteen of 95 (14.7%) sheep and goats and 14/35 camels (40%) sampled in Palestine were seropositive for WNV. Of the horses that were sampled twice, 82.8% were seropositive for WNV at the first sampling, and all remained seropositive. Three of the seronegative horses, all from Palestine, converted to positive when resampled (8.5%). The results indicate that domestic animals in Palestine were infected with WNV in the past, and the seroconversion indicates that WNV was circulating in Palestine in the summer of 2014. Control measures to prevent human infection should be implemented in Palestine. Anti WNV antibodies in domestic animals suggest that those species can be used as

    Full Text Available Israel is a country in the Near East consisting for 95% of the arid regions in which 60% of the territory are covered by the Negev Desert. Therefore, the water resources are scant here and formed mostly by atmospheric precipitations. In the period from 1989 to 2005 the average precipitations were 6 billion cu. m, of which 60–70% were evaporated soon after rainfalls, at least 5% run down by rivers into the sea (mostly in winter and the remaining 25% of precipitations infiltrated into soil from where the greater part of water got into the sea with ground waters. In Israel there are two groups of water resources: surface and underground. Israel is not rich in surface waters. The natural reservoir of surface fresh water is the Kinneret Lake in the northeast of the country. It gets water from the Jordan River and its tributaries. The average annual amount of available water of this lake is around 370 million cu. m, which accounts for one-third of the country’s water needs and still higher share of the drinking water needs. The greater part of fresh waters (37% of water supply of Israel as of 2011 in this country is supplied from ground water sources. Owing to insufficiency of available natural resources, unevenness of precipitations by years and seasons and with the growth of the population and economic development the issues of provision with the quality drinking water of the population as well as agriculture and industry, rehabilitation of natural environment cause permanently growing concern. In view of the water shortage untiring efforts have been taken to improve the irrigation efficiency and to reduce water use by improving the efficacy of irrigation techniques and application of advanced system management approaches. Among the water saving technologies applied in Israel there are: drop irrigation, advanced filtration, up to date methods of water leak detection from networks, rainwater collection and processing systems.

    A new relativistic definition of the reduced mass (μ 12 ) of a q bar q pair, so as to be in conformity with the standard Wightman-Garding definition of its relative four-momenta q μ , is introduced into the kernel of an ongoing Bethe-Salpeter (BS) program on a two-tier basis. The new definition of μ 12 (involving the hadron mass M) is found to produce a natural Regge asymptotic behavior (M 2 ∼N) in the hadron mass spectra, while retaining the property of an asymptotically linear (∼r) confinement in the three-dimensional structure of the BS kernel. The relativistic structure of μ 12 is responsible for a significant improvement in the fits to the ground-state masses of q bar q and Q bar q mesons as compared to its nonrelativistic definition m 1 m 2 /(m 1 +m 2 ). The leptonic decay constants f p and the charge radii thus calculated are also in excellent agreement with data (π,k) where available, while f p predictions for Q bar q mesons have good overlap with recent lattice predictions. Further, the scaling property (∼k μ -2 ) of the hadron's electromagnetic form factor at large k 2 is a consequence of the ''on-shell'' form of its null-plane wave function. All these results (which are indicated in the barest outline) are preceded by a perspective summary of the theoretical premises and practical working of the BS equation with a four-fermion interaction kernel as a necessary background on a two-tier basis

    Pharmaceutical drug shortages (DSs) are a global problem which presents challenges to countries around the world. Shortages of pharmaceutical products may have a direct detrimental impact on public health and patients' wellbeing by causing delayed, or even lack of, treatment. Moreover, DSs may force both patients and caregivers to use unfamiliar drugs, which could lead to medication errors. The objective of our study was to analyze DSs in Israel during the years 2013-2015, assessing their etiology and exploring the steps taken for their mitigation and prevention. The database of the Israeli Ministry of Health (MoH) on drug shortages contains all the DSs recorded in Israel since 2013, detailing the cause of the DS, its duration, steps taken in its' management and the availability of generic or therapeutic alternatives. Selected examples of DSs from the database are described in this paper in order to identify the causes of DSs, the scope of the problem and possible solutions. Additionally, we have reviewed the recent activities performed by European Medicine Agency (EMA) and the American Food and Drug Administration (FDA) in their efforts to minimize this problem. Several factors contributing towards DSs in Israel were identified, including quality problems in both the final drug product and in the raw materials, upgrades and improvements of the manufacturing process required by the MoH, manufacturing by a sole supplier, dramatic price decrease in off-patent medications causing the manufacturer to discontinue the distribution of the product in Israel, just-in-time inventory control, and others. One of the most important steps in managing drug shortages was identified to be early notification of the shortage by the Marketing Authorization Holder (MAH) to the MoH. In 2013, the Israeli MoH updated the regulation on drug shortages instructing MAHs on their obligation of early notification to the MoH. Furthermore, various steps dealing with marketing withdrawal of drugs

    Israel is a country with diverse and rapidly changeable environments where is localized a giant number of archaeological objects of various age, origin and size. The archaeological remains occur in a complex (multi-layered and variable) geological-archaeological media. It is obvious that direct archaeological excavations cannot be employed at all localized and supposed sites taking into account the financial, organizational, ecological and other reasons. Therefore, for delineation of buried archaeological objects, determination their physical-geometrical characteristics and classification, different geophysical methods are widely applied. The number of employed geophysical methodologies is constantly increasing and now Israeli territory may be considered as a peculiar polygon for various geophysical methods testing. The geophysical investigations at archaeological sites in Israel could be tentatively divided on three stages: (1) past [- 1990] (e.g., Batey, 1987; Ben-Menahem, 1979; Dolphin, 1981; Ginzburg and Levanon, 1977; Karcz et al., 1977; Karcz and Kafri, 1978; Tanzi et al., 1983; Shalem, 1949; Willis, 1928), (2) present [1991 - 2008] (e.g., Bauman et al., 2005; Ben-Dor et al., 1999; Ben-Yosef et al., 2008; Berkovitch et al., 2000; Borradaile, 2003; Boyce et al., 2004; Bruins et al., 2003; Daniels et al., 2003; Ellenblum et al., 1998; Eppelbaum, 1999, 2000a, 2000b, 2005, 2007a, 2007b, 2008b; Eppelbaum and Ben-Avraham, 2002; Eppelbaum and Itkis, 2000, 2001; 2003, 2009; Eppelbaum et al., 2000a, 2000b, 2001a, 2001b, 2003a, 2003b, 2004a, 2004b; 2005, 2006a, 2006b, 2006c, 2006d, 2007, 2009a, 2009b; Ezersky et al., 2000; Frumkin et al., 2003; Itkis and Eppelbaum, 1998; Itkis, 2003; Itkis et al., 2002, 2003, 2008; Jol et al., 2003, 2008; Kamai and Hatzor, 2007; Khesin et al., 1996; Korjenkov and Mazor, 1999; Laukin et al., 2001; McDermott et al., 1993; Marco, 2008; Marco et al., 2003; Nahas et al., 2006; Neishtadt et al., 2006; Nur and Ron, 1997; Paparo, 1991; Porat

    Studies of traditional healers in various cultures describe their initiation into the healing profession as a climax that constructs their professional and personal identity. Literature emphasizes the healers' intense association with the culture in which they work, as reflected in the initiation narratives that healers in various cultures recount. In this article we reveal unique initiation stories and identity formation from Palestinian nonconventional healers in Israel who described a cross-cultural journey: After studying healing traditions of foreign cultures and on returning to their own cultural environment, they developed a unique and complex combination of healing values and traditions. We examine the stories of these healers, whose personal and professional identities are affected by cultural, political, and social contexts. We note the blending of healing traditions and practices, and the changes in identity, assessing them against cultural processes that many Palestinians in Israel have been undergoing over the past few decades.

    Full Text Available This article examines the involvement of civil society organizations in human rights education (HRE in Israel. Focussing on the educational programs of the Association for Civil Rights in Israel (ACRI, as a qualitative instrumental case study, this article examines the conceptions of good citizenship embedded in these programs. Specifically, the article analyzes the educational programs’ goals, content, targeted populations, and practices. The analysis revealed that ACRI’s HRE model reflect four ideal types of citizens: citizen of a democratic liberal state, citizen of a participatory polity, citizen of an ethical profession, and citizen of an empowered community. These constitute a multilayered human rights discourse that enables ACRI to engage differentially with various sectors and populations, while still remaining faithful to the ethno-national parameters of a Jewish and democratic state political framework.

    2009-08-01

    The identification of the molecular basis of deafness in the last decade has made a remarkable impact on genetic counseling and diagnostics for the hearing impaired population. Since the discovery of the most prevalent form of deafness associated with mutations in the GJB2 (connexin 26) gene, many other genes have been found worldwide, with a subset of these, including unique mutations, in Israel. Here, we review the current status of deafness genes in Israel and report one known mutation in a syndromic form of deafness, Usher syndrome, described in the Jewish Israeli population for the first time. In the future, the identification of specific mutations may be relevant for specific types of treatment.

    Full Text Available Abstract Shared decision making (SDM - involving patients in decisions relevant to their health - has been increasingly influential in medical thought and practice around the world. This paper reviews the current status of SDM in Israel, including efforts to promote SDM in the legislation and healthcare system, its influence in medical training and the national health plans, and funding for SDM-related research. Published studies of SDM in Israel are also reviewed. Although informed consent and patients' right to information are regulated by Israeli law, little provision is made for SDM. Further, there are few organized programs to promote SDM among medical professionals or the public, and governmental support of SDM-related research is minimal. Nonetheless, patients have begun to influence litigation in both formal and informal capacities, medical schools have begun to incorporate courses for improving physician-patient communication into their curricula, and the largest national health plan has initiated a plan to increase public awareness. A review of the limited research literature suggests that although patients and physicians express a desire for greater patient involvement, they often have reservations about its implementation. Research also suggests that despite the positive effects of SDM, such an approach may only infrequently be applied in actual clinical practice. In conclusion, though not actively promoting SDM at present, Israel's universal coverage and small number of health plans make rapid, widespread advances in SDM feasible. Israeli policymakers should thus be encouraged to nurture burgeoning initiatives and set plausible milestones. Comparing the status of SDM in Israel with that in other countries may stimulate further advancement.

    The economic development of Israel was studied quantitatively, correlating the gross national product with the energy used, the number of employed persons, and the capital stock. A production function in the form of that of Cobb-Douglass was found, which describes the GNP in terms of these three factors with a very high accuracy. The development of electricity consumption is also examined and correlated to demographic and economic developments. (author)

She was initially misdiagnosed with staphylococcal and pseudomonal cellulitis. Although cutaneous leishmaniasis is seen only rarely in the United States, it should be considered when diagnosing new skin lesions after travel to affected countries.

    1993-01-01

    The study of liquid metal MHD in Israel commenced in 1973. Initially it was concentrated mainly on laminar flows influenced by external magnetic fields. In 1978 a liquid metal MHD energy conversion program was started. This program was developed at the Center for MHD Studies at Ben-Gurion University in Beer-Sheva, with the participation of specialists from the Technion, the Hebrew University of Jerusalem, Israel Atomic Energy Commission, and others. The program was sponsored initially by the Israel Ministry of Energy and Infrastructure, and later by the Ministry of Industry and Trade. Since 1980, Solmecs, a private commercial company has become a major factor in the development of liquid metal MHD in Israel. From the very beginning the program was based on broad international cooperation. A number of overseas institutions and individuals became participants in the program. Through extensive research and evaluation of a number of concepts of liquid metal MHD power generation systems, It was established that the most promising concept, demanding a relatively short period of development, is the gravitational system using heavy metals (lead, lead alloys) as the magneto-hydrodynamic fluid and steam or gases as thermodynamic fluids. This concept was chosen for further development and industrial application, and the program related to such systems was named the Etgar Program. The main directions of research and development activities have been defined as follows: investigations of physical phenomena, development of universal numerical code for parametric studies, optimization and design of the system, material studies, development of engineering components, building and testing of integrated small-scale Etgar type systems, economic evaluation of the system and comparison with conventional technologies, development of moderate scale industrial demonstration plant. At this time 6 items have been fully implemented and activities on the last item were started. (author)

    Full Text Available Newborn screening (NBS programs for severe combined immunodeficiency (SCID, the most severe type of primary immunodeficiency, are being implemented in more and more countries with every passing year. Since October 2015, SCID screening via T cell receptor excision circle (TREC quantification in dried blood spots (DBS has been part of the Israeli NBS program. As an NBS program in its infancy, SCID screening is still evolving, making gathering input from the various programs crucial for compiling an ideal screening algorithm. The relatively high rate of consanguineous marriages in Israel, especially among non-Jews, correlates with an increased incidence of SCID. The Israeli algorithm uses a commercial kit and consists of a two-Guthrie card confirmation system prior to referral to a national immunology center. Preliminary data from the first year and a half of SCID screening in Israel has identified a surprisingly high prevalence of DNA cross-link repair protein 1c (DCLRE1C; ARTEMIS mutations as the cause of SCID in Israel. The clinically unbiased nature of SCID screening helps unearth mild/leaky SCID phenotypes, resulting in a better understanding of true SCID prevalence and etiology.

    Full Text Available Aim/Purpose: To develop and introduce a questionnaire that investigates the informing needs, information-seeking behavior, and supplier selection of procurement officers in Israel. The questionnaire’s internal consistency reliability is given. Additionally, we describe the demographic description of the procurement officers in Israel. Background: Procurement science is an important field that affects firms’ profits in the private sector and is significant to growth, innovation, sustainability, and welfare in the public sector. There is little research about the informing needs of procurement officers in general and particularly in Israel. Methodology: A quantitative questionnaire that is sent to all the procurement officers in Israel’s procuring association. Contribution: The questionnaire that is developed in this paper may be used by other researchers and practitioners to evaluate the information needs of procurement officers. Findings: The typical procurement officer is male, with a bachelor degree and is digitally proficient. Recommendations for Practitioners: The procuring side can use the questionnaire to develop better tools for obtaining information efficiently. The supplying side can use this knowledge to improve its exposure to potential customers and address its customer’s needs better. Recommendation for Researchers: The questionnaire can address theoretical questions such as how digital literacy affects the procuring process and provide empirical findings about active research areas such as supplier selection and information-seeking behavior. Future Research: Future research will examine the relationship between the various variables and demographic features to understand why specific information needs and information-seeking behaviors arise.

    2006-01-01

    This article surveys the botanical composition of 40 Muslim graveyards in northern Israel, accompanied by an ethnobotanical study of the folkloristic traditions of the use of these plants in cemeteries. Three groups of plants were found to be repeated systematically and were also recognized for their ritual importance: aromatics herbs (especially Salvia fruticosa and Rosmarinus officinalis), white flowered plants (mainly Narcissus tazetta, Urginea maritima, Iris spp. and Pancratium spp.) and Cupressus sempervirens as the leading cemetery tree. As endemic use we can indicate the essential role of S. fruticosa as the main plant used in all human rites of passage symbolizing the human life cycle. The rosemary is of European origin while the use of basil is of Indian influence. The use of white flowers as cemeteries plants reflects an old European influence and almost the same species are used or their congeners. Most of the trees and shrubs that are planted in Muslim cemeteries in Israel have the same use in ancient as well in modern European cultures. In conclusion, our findings on the occurrence of plants in graveyards reflect the geographic situation of Israel as a crossroads in the cultural arena between Asia and Europe. Most of the traditions are common to the whole Middle East showing high relatedness to the classical world as well as to the present-day Europe. PMID:16961931

    1993-01-01

    Nuclear energy utilization has been facing substantial difficulties worldwide in the last decade. Safety problems led to public distrust and economic performance did not always fulfill the utilities expectations. However, recent events in Israel and worldwide call for a review of national energy policy. Nuclear power should be considered a viable solution to energy problems which may confront us in the future. The main objective of incorporating nuclear power in Israel's energy program is to minimize its total dependence on imported fossil fuel, which may be hindered by fluctuations in fuel prices and disruptions in regular supply. In order to achieve this goal, 50% of the electric power generation should be obtained from nuclear power plants. Thus, long-term planning is required, expending over a period of 25 to 30 years, for implementation of a nuclear program. The projected Israeli installed capacity for 1995 is 5600 MW at an annual development rate of 4%. If this trend continues, it will require installation of approximately 5 units, 600 MW each, every ten years, about half of which should be nuclear. It is in Israel's interest to opt for an advanced type of nuclear reactor, that could provide many important advantages, e.g. improved safety, prolonged life, high load factor, etc. A high local participation in the planning and construction of plant is also desirable.

    2014-03-01

    Full Text Available Since 1948, the Government Press Office of Israel has been collecting and producing an extensive archive of photographs representing the birth and development of the Israeli nation state. Digitized and published online, this archive functions as a visual memorial of Israel, an example of what Jan Assman calls “bonding memory”, a form of memory that connects individuals to a political body, and which acts to frame a collective national identity. In 2011, the copyright terms of this archive were changed to encourage the circulation and reuse of images. This decision echoes a broader trend towards the “opening” of large data sets on the Web (“open data”, “open archives”, “open government”. At the same time, the ongoing Arab-Israeli conflict and the existence of contesting narratives of the creation of Israel threaten the integrity of the official national memory. In this context, what are the conditions and limits of “opening” the national photographic archive? Examining contemporary ideology of the “open” in new media discourses and the free culture movement, this paper investigates the conditions of circulation and appropriation of memory and the role of copyright as a potential tool to control freedom of expression.

    Full Text Available Israel is a popular tourist destination which has by afflicted by varying levels of terrorism against civilians over the course of its history. A longitudinal analysis of data pertaining to tourism and terrorism is undertaken to examine how terrorism affects patterns of tourism. It is found that on the macro-level, tourism to Israel continues to grow although it experiences periodic declines corresponding with times of high terrorist activity. National and religious subpopulations of tourists react differently terrorism at the destination. Overall, Jews are proportionally more likely than non-Jews to continue to visit Israel during times of conflict, but this varies among Diaspora communities. Moreover, among US Jewish tourist, the strongly religious populations represented a greater percentage of visitors during years of high terrorism. This preliminary analysis explores how internal structural features of the Jewish community (such as Jewish educational settings and family ties to Israelis, external factors of the home country (such as anti-Semitism or the economic situation and national and cultural value orientation affect tourism patterns. The impact of these factors on tourism deserves continued research.

    A nationwide surveillance of X-ray machines is carried out in Israel by the Research Institute for Environmental Health, Ministry of Health. At present, diagnostic X-ray machines are surveyed at least once every two years, while dental machines are surveyed once every five years. The investigated parameters include measurement of output, scattered radiation, X-ray-light-field alignment, HVL, inherent filtration, structural shielding, etc. In order to compare X-ray techniques used in different hospitals in Israel, the NEXT (Nationwide Evaluation of X-ray Trends) program, which was developed by the BRH (Bureau of Radiological Health, USPHS) was utilized. On the basis of the findings of this project, necessary correction steps were taken in order to reduce the radiation doses to both personnel and patients. Further activities of the Institute include the estimation of doses delivered to pregnant women who were irradiated during the gestation period. This information is sent to a professional committee, which decides whether or not to perform an abortion. Recently, the new recommendations of ICRP 26 (International Commission on Radiological Protection) were implemented in Israel. Therefore, at present doses over 150 mR/month are reported to the Institute by the Soreq Personal Dosimetry Service, and the causes of this exposure are investigated. (author)

    Full Text Available Este artículo aborda el establecimiento del peculiar régimen de dominación dual de Israel desde 1967, argumentando que la estructura de este régimen convierte a las élites militares en un actor político crucial. El régimen dual se basa en la separación geográfi ca entre dos regímenes diferentes de control y legitimación. Argumentaré aquí que la guerra de 1967 fue un parteaguas histórico, ya que acarreó un desdibujamiento de las fronteras israelíes y la llegada de un régimen dual que legitima la división del poder político entre las élites militares y civiles que gobiernan Israel-Palestina. Mi objetivo es mostrar las contradicciones inherentes de este régimen dual de “ocupación democrática” y así arrojar luz sobre la dinámica de los espacios políticos de acuerdo a la población ocupada: su apertura, por reconocimiento y negociación, y su cancelación, por el uso de la violencia.

  17. Covert Diplomacy Between Israel and Egypt During Nasser Rule

    Full Text Available The history of Egypt and Israel consists of four wars and hundreds of border incidents that have taken the lives of tens of thousands of people. It seems that only the rise to power of a leader in the stature of Anwar Sadat could put an end to this bloody circle, because the previous president, Gamal Abdel Nasser, was not willing to hold any kind of political contact with Israel. But Nasser’s reign involved constant political contact between Egypt and Israel, most of whom remain confidential. This article attempts to examine whether any of these contacts were likely to succeed and yield a peace treaty between the two countries, an agreement that could have prevented three wars and saved the lives of so many people on both sides. It will do so by examining these contacts, their characteristics, and the reasons for their failure, while dividing them into three periods: the 1948 war to the 1956 war, the 1956 war to the 1967 war, and the 1967 war to the death of Nasser in 1970.

    Current empirical literature on sexual harassment in schools is mostly based on nonrepresentative samples of middle-class high-school Caucasian female students. Thus the scope of research regarding gender, age, and cultural differences is very limited. This article reports on findings on sexual harassment in Jewish and Arab schools in Israel with regard to gender, age, and cultural differences. The study is part of the first national survey on school violence in Israel. The representative sample includes 10,400 students in grades 7 through 11 attending public schools in Israel. Students were asked to report whether they were victims of specific acts of sexual harassment in school during the month before the survey. Overall, 29.1% of the students were victims of at least one act of harassment. The more common acts were to show offensive pictures or to send obscene letters, to take off or to try to take off part of the student's clothing, and to try to kiss a student. The most vulnerable groups are the Arab boys and 8th grade students. Report rates were the lowest among Arab girls. Sexual harassment is prevalent in Israeli schools. The pattern of victimization is different for boys and girls and for students in Jewish and Arab schools. These patterns are a complex phenomenon that must be considered in the intervention and policy measures addressing sexual harassment at school.

    Full Text Available In Israel today, with a total population of over 6 million persons, the Division for Mental Retardation (DMR provides services to 23,000 persons with intellectual disability (ID. Of the 23,000, residential services are provided to more than 6,000 in close to 60 residential centers, another 2,000 are provided residential care in hostels or group homes in the community in about 50 locations, while the rest are served with day-care kindergarten, day-treatment centers, sheltered workshops, or integrated care in the community. The first Snoezelen room (controlled multisensory stimulation in the DMR was established at the Bnei Zion residential care center in 1995. The Snoezelen method is now used in Israel in more than 30 residential care centers and 3 community settings. Since the year 2000, a physiotherapist has been employed in order to supervise the treatment and development of the method nationally. Professional staff meetings take place every 4 months. A certification course has been established on a national basis for individuals from different professions (occupational therapists, physiotherapists, teachers, music therapists, nurses, speech therapists, or caregivers. Snoezelen has proved to be an important instrument and a powerful therapeutic tool among the various treatment modules employed in Israel for persons with ID. This paper presents the concept illustrated with two case stories.

    2000-11-01

    The postmortem examination and identification procedures performed by medical and law enforcement personnel involved in mass disaster management in Israel are reported. The Israel National Police, the Israel Defense Forces, and the L. Greenberg Institute of Forensic Medicine's experts examined 171 victims who died in 21 incidents of suicidal terrorism. The trauma sustained by the victims and perpetrators of suicidal bombings included complete body disruption and explosive, flying missile, and blast injuries. The modus operandi of the perpetrators, reconstructed from the distribution and type of injury of the victims, is discussed. Fifty-five victims perished in open space bombings and 91 inside buses. All perpetrators of these bombings died at the time of the incident regardless of their location. Identification of the victims was achieved using fingerprints, dental records, medical intervention signs, anatomic variation, genetic profile, and personal recognition. Prompt identification of the perpetrators allowed speedy apprehension of the accomplices and prevention of similar attacks. Collaboration between the different forensic, military, and law enforcement teams increased the efficiency of disaster management efforts.

    Hard exclusive leptoproduction of real photons from an unpolarized proton target is studied in an effort to elucidate generalized parton distributions. The data accumulated during the years 1996-2005 with the HERMES spectrometer are analyzed to yield asymmetries with respect to the combined dependence of the cross section on beam helicity and charge, thereby revealing previously unseparated contributions from deeply virtual Compton scattering and its interference with the Bethe-Heitler process. The integrated luminosity is sufficient to show correlated dependences on two kinematic variables, and provides the most precise determination of the dependence on only the beam charge. (orig.)

    The multicritical behaviour of the spin-((3)/(2)) Blume-Emery-Griffiths model with bilinear and biquadratic exchange interactions and single-ion crystal field is studied on the Bethe lattice by introducing two-sublattices A and B within the exact recursion equations. Exact expressions for the free energy, the Curie or second-order phase transition temperatures, as well as for the magnetization and quadrupolar moment order parameters are obtained. The general procedure of investigation of critical properties is discussed and phase diagrams are obtained, in particular, for negative biquadratic couplings. The phase diagram of the model exhibits a rich variety of behaviours. Results are compared with other approximate methods

    We employ the framework of the Bethe-Salpeter equation under a covariant instantaneous ansatz to study the leptonic decays of vector mesons. The structure of the hadron-quark vertex function {gamma} is generalized to include various Dirac covariants (other than i{gamma} . {epsilon}) from their complete set. They are incorporated in accordance with a naive power counting rule order-by-order in powers of the inverse of the meson mass. The decay constants for {rho}, {omega} and {phi} mesons are calculated with the incorporation of leading-order covariants.

  7. Nuclear war between Israel and Iran: lethality beyond the pale

    Science.gov (United States)

    2013-01-01

    Background The proliferation of nuclear technology in the politically volatile Middle East greatly increases the likelihood of a catastrophic nuclear war. It is widely accepted, while not openly declared, that Israel has nuclear weapons, and that Iran has enriched enough nuclear material to build them. The medical consequences of a nuclear exchange between Iran and Israel in the near future are envisioned, with a focus on the distribution of casualties in urban environments. Methods Model estimates of nuclear war casualties employed ESRI's ArcGIS 9.3, blast and prompt radiation were calculated using the Defense Nuclear Agency's WE program, and fallout radiation was calculated using the Defense Threat Reduction Agency's (DTRA's) Hazard Prediction and Assessment Capability (HPAC) V404SP4, as well as custom GIS and database software applications. Further development for thermal burn casualties was based on Brode, as modified by Binninger, to calculate thermal fluence. ESRI ArcGISTM programs were used to calculate affected populations from the Oak Ridge National Laboratory's LandScanTM 2007 Global Population Dataset for areas affected by thermal, blast and radiation data. Results Trauma, thermal burn, and radiation casualties were thus estimated on a geographic basis for three Israeli and eighteen Iranian cities. Nuclear weapon detonations in the densely populated cities of Iran and Israel will result in an unprecedented millions of numbers of dead, with millions of injured suffering without adequate medical care, a broad base of lingering mental health issues, a devastating loss of municipal infrastructure, long-term disruption of economic, educational, and other essential social activity, and a breakdown in law and order. Conclusions This will cause a very limited medical response initially for survivors in Iran and Israel. Strategic use of surviving medical response and collaboration with international relief could be expedited by the predicted casualty

    2018-04-01

    We develop an efficient method to perform density matrix renormalization group simulations of the SU(N ) Heisenberg chain with open boundary conditions taking full advantage of the SU(N ) symmetry of the problem. This method is an extension of the method previously developed for exact diagonalizations and relies on a systematic use of the basis of standard Young tableaux. Concentrating on the model with the fundamental representation at each site (i.e., one particle per site in the fermionic formulation), we have benchmarked our results for the ground-state energy up to N =8 and up to 420 sites by comparing them with Bethe ansatz results on open chains, for which we have derived and solved the Bethe ansatz equations. The agreement for the ground-state energy is excellent for SU(3) (12 digits). It decreases with N , but it is still satisfactory for N =8 (six digits). Central charges c are also extracted from the entanglement entropy using the Calabrese-Cardy formula and agree with the theoretical values expected from the SU (N) 1 Wess-Zumino-Witten conformal field theories.

    In an era of global and local nursing shortages, nursing turnover has negative consequences in terms of diminished quality of care, increased costs and economic losses and decreased job satisfaction. To examine the turnover rate of registered nurses in Israel by assessing the varying degree of turnover between economic sectors, between hospital and community facilities, and/or between types of hospitals; and by examining potential predicting factors of turnover among registered nurses. A national phone survey was undertaken in Israel consisting of a random sampling of registered nurses of working age (up to age 60). The subjects comprised 10% of a national database of 32,000 registered nurses. The turnover rate among working nurses in Israel currently stands at 23%. In addition, 13% of employed nurses have taken a temporary leave of absence for a period greater than 6 months in the past 10 years, most up to 1 year. While job satisfaction rates were relatively high (72%), Professional satisfaction rates were 60% with no significant difference between hospital and community nurses. The turnover rate of registered nurses from a hospital setting to the community was significantly higher (pcommunity registered nurses to hospitals. Predicting factors of turnover were found to be: young age, part-time work, lack of advanced professional education, academic education and low satisfaction with the nursing profession. The shift of nursing workforce is mainly from hospitals to community health settings. There is a need to monitor and understand the characteristics of job and professional satisfaction among hospital nurses in order to implement crucial organizational interventions and retain hospital nursing staffs. Since young nurses, nurses working part time and nurses with no advanced professional and academic education, tend to move more than others, efforts should be targeted at these specific groups.

    2016-11-01

    This is an invited paper for a special issue on international perspectives on training and practice in clinical neuropsychology. We provide a review of the status of clinical neuropsychology in Israel, including the history of neuropsychological, educational, and accreditation requirements to become a clinical neuropsychologist and to practice clinical neuropsychology. The information is based primarily on the personal knowledge of the authors who have been practicing clinical neuropsychology for over three decades and hold various administrative and academic positions in this field. Second, we conducted three ad hoc surveys among clinical and rehabilitation psychologists; heads of academic programs for rehabilitation and neuropsychology; and heads of accredited service providers. Third, we present a literature review of publications by clinical neuropsychologists in Israel. Most of the clinical neuropsychologists are graduates of either rehabilitation or clinical training programs. The vast majority of neuropsychologists are affiliated with rehabilitation psychology. The training programs (2-3 years of graduate school) provide solid therapeutic and diagnostic skills to the students. Seventy-five percent of the participants in this survey are employed at least part-time by public or state-funded institutions. Israeli neuropsychologists are heavily involved in case management, including vocational counseling, and rehabilitation psychotherapy. Conclusions and future goals: Although clinical neuropsychologists in Israel are well educated and valued by all health professionals, there are still several challenges that must be addressed in order to further advance the field and the profession. These included the need for Hebrew-language standardized and normalized neuropsychological tests and the application of evidence-based interventions in neuropsychological rehabilitation.

    It is well known that in the event of a shortage in generation capacity, it is inefficient if the electricity utility cuts off customers randomly. It is preferable to set up a market in service priority in which customers who have a greater need pay more for the right not to be cut off. We use an econometric model of outage costs in Israel to calculate the menu of priority rates by season and time of day. Top priority rates range from zero, when the loss-of-load probability (LOLP) is zero, to 8 cents (US) per kWh when the LOLP is greatest

    Full Text Available House prices in Israel have registered unprecedented growth rates in the last few years. At first glance, these hikes could be explained by the evolution of fundamentals such strong population growth and favourable macroeconomic conditions, i.e. low interest rates. However, further investigation is needed in order to explore whether there is a misalignment between house prices and their fundamentals. Firstly, this paper investigates the role of construction costs in the evolution of house prices. Secondly, this contribution decomposes the “price-to-rent” ratio into fundamentals, frictions and bubble episodes for a better understanding of the recent trends of the market.

  11. Intimate Partner Jealousy and Femicide Among Former Ethiopians in Israel.

    Edelstein, Arnon

    2018-02-01

    Ethiopian immigrant women in Israel are overrepresented as victims of femicide; they are killed at more than 16 times the rate of the general population. This article suggests integrating current theoretical and empirical models to explain Ethiopian femicide, and stresses that considering psychological or sociocultural explanations as risk factors alone is not enough to understand this phenomenon. We distinguish between risk factors and triggers for femicide against Ethiopian women. While sociocultural and even psychological changes are risk factors for femicide, one, two, or three main triggers may activate such potential risk factors, such as the woman's willingness (WW) to leave the intimate relationship, sexual jealousy (SJ), and formal complaints against the abusive partner. The first two triggers are jealousy oriented. To analyze this phenomenon in Israel, we examined all court decisions on intimate partner homicide (IPH) from 1990 to 2010. After reading former studies on IPH and identifying important variables that could explain the phenomenon, we first catalogued the data in every decision and verdict according to main independent variables mentioned in the literature. The study population consists of first-generation immigrants, N = 194: native Israelis (47%), new immigrants from the former Soviet Union (FSU; 31%), and Ethiopians (16%). Our analysis of court decisions reveals that triggers containing jealousy components are responsible for 83% of femicide cases committed by Ethiopian men, in comparison with native Israelis (77%) and immigrant Russian men (66%) who murdered their intimate partners. In addition, there is a significant correlation among motive (jealousy), method of killing (stabbing), and "overkilling" (excessive force).

    Endevelt, Ronit

    2007-07-01

    Full Text Available The first lunch programs in Palestine were the “soup kitchens,” which were established in Jerusalem before the First World War to feed the poor. Then, in 1923, Henrietta Szold launched a lunch initiative in schools in order to supply basic nutrition to students. As the children at most of the schools prepared the meals themselves with local products, they also learned good, low-cost eating habits and the appropriate use of domestic goods and had educational goals as well. These educational goals were in line with Zionist ideology. School lunch programs lasted through the early years of the nation of Israel, albeit without official governmental support, but they came to an end amid the rising prosperity of the early 1970s. In 2004, in response to the alarming results of a food security survey conducted by the Ministry of Health, the Knesset passed a law establishing a new school lunch program on a trial basis. This article reviews the history of lunch programs in Israel, highlighting both their achievements and their limitations, in order to establish a framework for judging the success of the current school lunch policy.

  13. Assessing the options for a competitive electricity market in Israel

    International Nuclear Information System (INIS)

    Tishler, A.; Newman, J.; Spekterman, I.; Woo, C.K.

    2008-01-01

    In July 2006, the Israeli government affirmed its 2003 decision to reform the Israeli electricity industry, currently dominated by the Israel Electric Corporation (IEC), a government-owned vertically integrated electric utility. The reform calls for the deregulation and privatization of the generation and customer service segments of the industry, leaving transmission and distribution (T and D) regulated to provide open access to all end-users. This paper projects the performance of the post-reform market structure for the period 2007-2030 relative to that of the status quo. The post-reform generation market's prices are determined according to the Cournot conjecture. To mitigate excessive price volatility and surges, the generation market also includes a firm that is contracted to make peak electricity sales to customers at a pre-determined price, only when the competitive price exceeds the pre-determined level. Our results show (a) the post-reform retail prices for end-users will exceed those under the status quo; (b) the post-reform profits may not be sufficient to keep firms operating combined cycle generation units financially viable; and (c) the net benefit from deregulating the electricity sector in Israel will most likely be negative.

  14. Cost-benefit analysis of reforming Israel's electricity industry

    International Nuclear Information System (INIS)

    Tishler, A.; Newman, J.; Spekterman, I.; Woo, C.K.

    2006-01-01

    In June 2003, the Israeli government decided to reform the Israeli electricity industry, which is currently dominated by Israel electric corporation (IEC), a government-owned vertically integrated electric utility. The first step of the planned reform will be taken in 2006, when IEC will be functionally separated into generation, transmission, local distribution, and customer services. Immediately thereafter will be the second step, which by 2012 will result in the deregulation and privatization of the wholesale generation and customer services. Transmission and distribution (T and D) services will remain regulated but will be available to all T and D users under mandatory open access. This paper summarizes a cost-benefit analysis of the government's reform plan. Relative to a regulated regime, the government's plan, even if carried out flawlessly, may only yield a small net benefit. However, it entails a large increase in electricity producer profit and government tax receipt, at the expense of electricity consumers. A less-than-perfect transition to competition can easily wipe out the potential gain of the government plan. Market reform experience to date shows that electricity market reform can easily fail, and the factors for success do not exist in Israel. Since the outcome of a failing reform can be disastrous, it will be imprudent to implement the government's plan in 2006, when the current electricity law expires. Hence, we recommend performance-based regulation for the period of 2006-2010. Subject to an updated cost-benefit analysis, possible decentralization, privatization and competition may follow

    2017-07-17

    Chronic diseases pose unique social challenges beyond traditional health considerations that require specific attention. In this report, we examine the case of a middle-aged woman with ulcerative colitis, living in Southern Israel. Trust between the patient and physician is shown to positively influence a variety of therapeutic outcomes and should be considered a fundamental component of successful care. In context of the military conflict between Israel and Gaza, the needs of patients with chronic diseases cannot be forgotten. The work environment is also identified as an area of particular concern, as a supportive work environment is essential in order to maintain satisfaction in the workplace and sustain a high quality of life. Out-of-pocket costs for medications are confirmed to be a significant barrier to adherence. Better understanding of patients’ financial capabilities, along with affordable therapeutic interventions, will alleviate healthcare-related financial burdens and improve health outcomes. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

  16. Suicide in Judaism with a Special Emphasis on Modern Israel

    Directory of Open Access Journals (Sweden)

    Eliezer Witztum

    2012-08-01

    Full Text Available Judaism considers the duty of preserving life as a paramount injunction. Specific injunctions against suicide appear in the Bible, Talmud, and thereafter. Nevertheless, Jewish tradition emphasizes that one should let himself be killed rather than violate cardinal rules of Jewish law. Mitigating circumstances are found for the six deaths by suicide mentioned in the Bible, for example to account for one's sins, or avoid shameful death. Heroic suicide is praised throughout the Jewish history, from the suicide of Samson and the collective suicide in Masada, to the collective readiness of Jews in Medieval times and during the Holocaust to kill themselves rather than succumb to their enemies. Suicide rates for Jews are lower than those of Protestants and Catholics. Similarly, suicide rates in Israel are lower in comparison to Europe and North America, although being higher than those in most Moslem Asian and North African countries. This low rate of suicide is found in Jewish Israelis of all ages, including in adolescents. Elevated suicidal risk may be found in specific sub-populations, including male Israeli soldiers, immigrants from the former USSR and Ethiopia, in particular adolescent immigrants from the former USSR, elderly Holocaust survivors, and young Israel-Arab women. The meaning of these findings is discussed according to different socio-cultural perspectives.

  17. Asbestos exposure in Israel: findings, issues and needs

    1984-02-01

    In Israel, since the 1950s, at least several thousand workers, their wives and children, and possibly many others, have been or still may be exposed to hazardous amounts of airborne asbestos fibers. These are found both in asbestos-based industries (asbestos cement, textiles and brake linings) and trades with asbestos exposure (construction, shipyard repair, boiler maintenance, insulation work). These people are at increased risk for disability or illness, or for premature death from asbestosis, from lung cancer, from exacerbation of preexisting respiratory disease (especially if they smoke), from mesothelioma, from gastrointestinal cancer, and from other malignancies. Although there has been progress, much still has to be done in the areas of legislation, standard setting, exposure control, technology, surveillance, smoking cessation, and medical care and follow-up. Compensation is needed to care for those workers currently or previously exposed, as well as for their families and others at risk. A national policy for protecting and caring for those formerly or currently exposed is indicated by the review of the situation in Israel.

    2010-08-01

    This paper has two objectives. The first is to examine the Israeli long-term care (LTC) system that is marked by rapidly increasing demands, and a multitude of public and private LTC arrangements. The second is to propose a reform to improve the system's efficiency and equity. The paper studies the LTC services in Israel, and the private-public composition in funding, fund holding, and provision of LTC. It focuses on structural deficiencies in the organization of each of these functions separately, and in combination. In many countries LTC has evolved in a patchwork fashion that at some point in time needs rethinking and rationalization. Israel is a case in point. In spite of numerous LTC arrangements supported by the state, in the absence of a comprehensive strategy, these have not generated a coherent system that can deal efficiently and equitably with existing and fast growing LTC needs, on the one hand, and the resources available to it, on the other. The current system is fragmented. It provides limited coverage and insufficient benefits in a troublesome fashion to public. The findings suggest that Israel can achieve at least in the short term, universal entitlement to LTC at lower financial and social cost, than the current costs of the system. In the medium and long term, the country will need to consider the trade between the burden of direct care on households or the tax burden of publicly supported and organized care. To remedy the situation the paper suggests a two-planked reform. The first is integration of the current fragmented publicly supported system while deciding on LTC either as a "social endeavor" under a separate authority responsible for implementing the public LTC budget, or as a "medical endeavor", putting this responsibility under the Israeli sickness funds. The second plank, building on the first, comprises extension of universal entitlement to LTC. Such an extension would increase public spending in the long term; simultaneously, it

    Full Text Available Analysis of the Israel's Foreign Policy is one of the important issues concerned by the researchers of the international and regional affairs. Israel's Foreign Policy in years 2003-2015 has witnessed a lot of events. In these years, transformation of the Iraq's internal structures including the fall of the Baath Regime in Iraq and appearance of the terroristic group of Dashi (ISIS in this country has provided new opportunities and challenges for the Israel's Foreign Policy. In this regard, establishment of a republic system in Iraq and the reinforcement of the Kurdish streams, specially during the current transformations and the increasing desires for the independence in Iraqi's Kurdistan, have paved the way for Israel to intensify its activities in the region. In this regard, the current study has approach the issue of Israel's Foreign Policy concerning Iraqi's Kurdistan during the years 2003-2015 with a descriptive analytic method. The achieved results show that the political reasons (alliance of the periphery and development of the strategic depth in closeness to Iran, economic (accessing the energy and mineral resources in Iraqi's Kurdistan, the importance of the Kurdistan's hydro-politic resources for Israel and the Israel's economical influence from the Nile to the Euphrates, military-security (presence in the strategic environment of Iran and the external threats in the Middle East, creation of an environmental crisis un the Kurdish region of the Middle East, weakening the Iraqi's central government and disintegration of this country, Israel's security-intelligence expansion, acquiring a strategic territory and getting out of isolation and the resolving the its legitimacy crisis, controlling the currents of thought in this region, all have been influential in thein Israel's Foreign Policy Concerning Iraqi's Kurdistan.

  1. Free data access: the experience of the Israel Meteorological Service

    2017-06-01

    Full Text Available This paper illustrates the benefits of changing from a commercial to an open access to climate data policy in the Israel Meteorological Service (IMS. The former commercial policy failed to provide expected economical revenues and notably increased the work time devoted to the management of the commercial structure and involved processes. At the same time, many companies and institutions tended to use data freely available in the Internet in spite of their worse quality or resolution in order to avoid the fees required to obtain data provided by the IMS. Changing to a free access to these data now allows an optimum use of climatic information and a significant reduction of bureaucratic tasks, freeing resources for research and development of new products.

    scientific publications. At the same time dentists published articles in the daily press in which they educated the public on dental hygiene and on modern dental techniques. This momentum was halted in the early 1940s as result of WWII and the Holocaust, but was quick to resume immediately thereafter. 1944 saw the publication of a professional dental Journal, which this issue is a continuation of. By the time the state of Israel was established in 1948, it had more than 900 active dentists, most of them organized in the Israel Dental Association. The only element which was still required to bridge the gap between the dentists in Israel and those in the rest of the modern world was an academic dental school. After more than 20 years in making, the school was opened in 1953 in Jerusalem. From that time on, Israel's dentistry enjoys a worldwide reputation and its dental school graduates teach and lecture in universities and in many dental forums around the globe.

    The unique nature of Israeli society as an immigrant society has also affected the prison population in Israel. This article focuses on a social and cultural phenomenon that particularly characterizes the prisoners of Russian origin, the phenomenon of tattoos. Using postmodernist theories, the article examines the function of the tattoo among Russian prisoners and the role it plays in constructing the criminal self-identity of these inmates in Israeli prisons. The tattoos observed during 2005-2006 among the Russian prisoners in four major Israeli prisons reflect the values of the Russian criminal subculture from which they evolved and were imported. This subculture is characterized by a hierarchical class structure and manifestations of machismo, domination, defiance, rebellion, and open antagonism against the Establishment and its representatives.

    2000-05-01

    The history of military psychiatry in Israel may be divided into 2 main periods. The first extended from the War of Independence in 1948, through the Sinai, Six Day and Yom Kippur Wars. Its outstanding feature was avoidance of the issue of combat stress reaction (CSR). The Yom Kippur War made the recognition of CSR inescapable, assisted in breaking up denial, and served as a stimulus for development of the next phase of the system. This second phase was characterized by impressive progress in all areas of military psychiatry. The rich experience accumulated during the wars, together with the assimilation of a research culture which began blooming, especially in the wake of the Lebanon War, aided the development and crystallization of concepts related to combat and non-combat military psychiatry alike. The build-up of the mental health organization overlapped field deployment of the Medical Corps.

    The timing of archeological industries in the Levant is central for understanding the spread of modern humans with Upper Paleolithic traditions. We report a high-resolution radiocarbon chronology for Early Upper Paleolithic industries (Early Ahmarian and Levantine Aurignacian) from the newly excavated site of Manot Cave, Israel. The dates confirm that the Early Ahmarian industry was present by 46,000 calibrated years before the present (cal BP), and the Levantine Aurignacian occurred at least between 38,000 and 34,000 cal BP. This timing is consistent with proposed migrations or technological diffusions between the Near East and Europe. Specifically, the Ahmarian could have led to the development of the Protoaurignacian in Europe, and the Aurignacian in Europe could have spread back to the Near East as the Levantine Aurignacian.

    This study examined the level of global self-esteem of Arab adolescents in Israel and its relationship to perceived academic status and aspirations, interpersonal relationships, community type, and various demographic variables. A group of 1,560 11th- and 12th-grade Israeli-Arab adolescents answered the Rosenberg Self-Esteem Scale (M. Rosenberg, 1965). The results revealed significant relationships (a) between global self-esteem and students' evaluations of their scholastic levels, their schools' academic levels, and their plans to take matriculation exams and (b) between self-esteem and family and peer relations. There was a significant relationship between self-esteem and community type. Participants living in cities and villages scored higher than those living in Bedouin townships. There were no significant gender differences or differences among grade levels.

    The data of an epidemiologic study of multiple primary malignant neoplasms in breast cancer patients in Israel are presented. During the 18-year period of the study 12,302 cases of breast carcinoma were diagnosed, and, of these, 984 patients (8%) had multiple primary malignant tumors. Forty-seven of these patients developed two multiple primary cancers. A significantly higher than expected incidence of second primary cancers occurred at the following five sites: the opposite breast, salivary glands, uterine corpus, ovary, and thyroid. Cancers of the stomach and gallbladder were fewer than expected. Treatment of the breast cancer by irradiation was associated with an increased risk of subsequent cancers of lung and hematopoietic system. The prognosis was mainly influenced by the site and malignancy of the second primary cancer. The incidence of multiple primary malignancies justifies a high level of alertness to this possibility in the follow-up of breast cancer patients

    The rise in the incidence of TB in Israel, mostly due to immigration from endemic areas, led to the establishment of a new TB control program which follows the guidelines of the World Health Organization (WHO). Reorganization of the TB infrastructure was enabled by specific legislative, administrative and budgetary measures initiated by the Ministry of Health (MOH) in conjunction with the Sick Funds. To present the theoretical and practical aspects of this new program to the physicians of Israel. The essence of this program is the use of directly observed therapy (DOT) for all patients together with centralization of TB care in nine national centers, closely supervised by the MOH. This centralization allows a critical mass of patients to be seen in each clinic, thus enabling the labor-intensive task of modern TB treatment, including the supervision and/or the administration of DOT, to be performed in a cost-effective manner. Day to day treatment is conducted by general community clinics and supervised by District Health Offices. Hospitalization, a relatively rare necessity in the new program, is available in two dedicated centers with modern isolation facilities. Centralized laboratory services provide timely susceptibility testing. Billing is simplified according to disease categories, using a global assessment of costs negotiated with the Sick Funds. Management and quality control of the program are carried out on an ongoing basis by the Department of TB and AIDS at the MOH. In the first two years that have elapsed since the inception of the program, almost 93% of cases have documented evidence of completion of treatment (under DOT), compared to 54% (without any treatment supervision) before the program came into effect.

    The number of paramedics in Israel is increasing. Despite this growth and important role, the emergency medical organizations lack information about the characteristics of their work. The objective of this study was to examine the characteristics of the paramedics' work, the quality of their working lives, the factors that keep them in the profession, or conversely, draw them away from it. Cross-sectional study conducted through telephone interviews of a random sample of 50% of the graduates of paramedic courses in Israel (excluding conscripted soldiers). The factors that attract paramedics to the profession have much to do with the essence of the job-rescuing and saving-and a love of what it involves, as well as interest and variety. Pressures at work result from having to cope with a lack of administrative support, paperwork, long hours, imbalance between work and family life, and salary. They do not come from having to cope with responsibility, the pressure of working under uncertain conditions, and the sudden transition from calm situations to emergencies. Dissatisfaction at work is caused by burnout, work overload, and poor health. Physical and mental health that impedes their ability to work is related to a sense of burnout and the intention to change professions. The findings about the relationships between health, job satisfaction, and burnout, coupled with the fact that within a decade, half of the currently employed paramedics will reach an age at which it is hard for them to perform their job, lead to the conclusion that there is a need to reconsider the optimum length of service in the profession. There also is a need to form organizational arrangements to change the work procedures of aging paramedics.

    Long term health impacts of internal displacement (ID) resulting from political violence are not well documented or understood. One such case is the ID of 300,000-420,000 Palestinian citizens of Israel and their descendants during the Nakba of 1948 (Palestinian Catastrophe). We aim to document the long term health impacts of this ID. We draw on data collected in 2005 from a nationwide random sample of 902 individuals aged 30-70. Research participants were interviewed in person after being selected through a multistage sampling procedure. About 24% of participants reported that either they or their families had been internally displaced. Palestinian internally displaced persons (IDPs), that is, those who were forcibly displaced and dispossessed from their homes and lands during the Nakba and its aftermath, as well as their families and descendants, and who reside within the current borders of Israel, had an odds ratio of 1.45 (95% CI = 1.02-2.07) for poor self-rated health (SRH) compared to non-IDPs after controlling for demographic, socioeconomic and psychosocial factors. No difference was found between IDPs and non-IDPs in limiting longstanding illness following control for confounders. Low socioeconomic position and chronic stress were significantly related to ID and to SRH. Our findings suggest adverse long term health impacts of the Nakba on the IDPs when compared to non-IDPs. We propose that these disparities might stem from IDPs' unhealed post-traumatic scars from the Nakba, or from becoming a marginalized minority within their own society due to their displacement and loss of collective identity. Given these long term health consequences, we conclude that displacement should be addressed with health and social policies for IDPs. Copyright © 2012 Elsevier Ltd. All rights reserved.

  12. Gender and disordered eating of adolescents in Israel.

    Studies from recent decades indicate that the ideal of thinness can be discerned in a growing dissatisfaction with weight and an increase of the prevalence of disordered eating at an earlier age of onset. The purpose of this study is to evaluate the prevalence of disordered eating (above the cutoff point of 30 on the EAT-40) among a normal population of school students in Israel. The study sample was composed of Israeli (Jewish) adolescents in grades 7 to 12 from four schools. Of 326 students approached (181 females and 142 males), 323 completed the self-report EAT-40 and a structured questionnaire that provided socio-demographic and other information. 41.5% of adolescents were not satisfied with their weight and 45.3% want to lose weight. A third of the sample engages in dieting behavior frequently; 6.1% of the adolescents have pathologic EAT-40 scores, with about three times as many girls as boys exhibiting disordered eating; 8.2% of the girls and 2.8% of the males show disordered eating (Ø=0.115, p times more with pathologic EAT scores than those who are satisfied with their weight (Ø=0.220; p times more pathologic EAT scores among adolescents who wish to lose weight than among those who do not wish to reduce their weight (Ø=0.237; p EAT scores were found among adolescents from different ethnic backgrounds or levels of religious observance. The prevalence of disordered eating among adolescents in Israel is higher than other countries in general, and among males in particular. There is a need for increased efforts to detect adolescents at risk for developing eating disorders, with the assistance of clinical tools. In addition an educational policy for disordered eating prevention should be instituted.

    Data on community-associated (CA) methicillin-resistant Staphylococcus aureus (MRSA) in Israel are scarce. The objective of this study was to characterize the major CA-MRSA clones in Israel. All clinical MRSA isolates detected in the community during a period of 2.5 years (2011-2013) from individuals insured by a major health maintenance organization in Israel were collected, with additional data from medical records. Antibiotic susceptibility patterns and staphylococcal chromosomal cassette mec (SCCmec) typing were determined. SCCmec IV and V isolates were further typed by pulsed-field gel electrophoresis (PFGE), spa typing, and detection of a panel of toxin genes. MRSA were detected in 280 patients, mostly from skin infections. Patients with SCCmec IV (n = 120, 43 %) were younger (p Israel, approximately 20 % are typical CA-MRSA clones, mainly USA300 and a local clone, t991.

    Lewis, Michael C; Grant, Gilbert J

    2015-01-01

    There is a chronic shortage of anesthesiologists in Israel. The study by Cohen et al. suggests that a marketing campaign may be one method of addressing this shortage. This commentary argues for a more comprehensive strategy based on the US experience. This would not only involve marketing as suggested by Cohen et al. but would also involve a fundamental change in the Israel anesthesia care model, as well as providing substantial financial incentives to young physicians. We believe that a combination of these approaches will help to alleviate the shortage of anesthesia providers in Israel. Creating a new class of physician extenders, namely, anesthesiologist assistants, would also provide an employment pathway for the skilled medical technicians trained by the Israel Defense Forces, and other non-physicians with an interest in anesthesiology.

    Despite the increased global prevalence and recognition of autistic spectrum disorder (ASD), it is still scarcely reported in the Arab world. Though Israel has a higher prevalence of ASD, a previous national survey of patients diagnosed between 1972 and 2004, demonstrated that 98% of them were of Jewish ancestry. The disproportional low number of Arab children with ASD in Israel is unclear but may reflect lower awareness and cultural bias. In the present study we collected clinical and demogr...

    This paper attempts to supply information on what motivated some 7000 Jewish divorcees to leave their countries of origin in the last decade and settle in Israel. The study also examines the differences in social integration of immigrant divorcees who came to Israel from different political systems--authoritarian or democratic regimes. Finally, the study examines the extent to which immigrant divorcees, who generally arrive in Israel with children, are to be considered as a "high risk" social group requiring special attention and particular aid. Of the 287,487 immigrants aged 15 years and over who arrived in Israel between 1970-1980, 53.7% were women (sex ratio: 860 males per 1000 females), and 3.6% were divorced. The findings indicate that there are significant differences between divorcees from Anglophone and Eastern European countries in their motivation for immigrating to Israel. The former decide to immigrate primarily for individual reasons--generally after divorce--expecting that immigration will increase chances of remarriage. In contrast, those who came from Eastern Europe are motivated by political, economic, and ideological reasons; the issue of immigration often sparks the divorce crisis. Divorcees from Anglophone countries are less socially isolated, more likely to meet veteran Israelis, and more satisfied with their life in Israel. Eastern European divorcees usually restrict their social contact to encounters with other immigrants from their country of origin, are less satisfied with their life in Israel, and feel themselves more isolated and frustrated. Despite the difficulties encountered by this group, it was found that there are no marked differences between divorcees and married immigrant women in social integration. In Israel, immigrant divorcees cannot be considered as a "high risk" social group.

  1. Israelologie: ’n Bybels-teologiese perspektief oor Israel se verlede, hede en toekoms

    Full Text Available Israelology: A Biblical-theological perspective of the past, present and future of Israel. Israelology, the study of Israel, is necessary for any theological system. In the past, God made unconditional covenants and other promises to Abraham and his descendants through Jacob. Not all Jews appropriate these blessings from God in faith. There has always been, however, a faithful remnant in Israel who believed the revelation and promises of God. Despite idolatry and repeated failure, even the unpardonable sin, God is faithful and has not cast away – not even temporarily – his people whom He foreknew. During the Church Age, the Jewish remnant is not only part of the Church but also of the nation of Israel. New Testament revelation does not cancel, change, transcend, spiritualise, or idealise unconditional and still-unfulfilled promises of God to Israel. The term ‘the seed of Abraham’ has multiple senses, and the fact that it can refer to the spiritual descendants of Abraham of non-Jewish descent does not change or cancel the promises that God made to the believing Jewish descendants of Abraham. Because God is faithful, Israel has a future. The present worldwide regathering of Jews to their homeland is happening in preparation for the judgement of the Tribulation Period. Christ will not return to the earth, however, until a future Jewish generation repent and call on the Lord. Then, a second worldwide regathering of faithful Jews to Israel will take place, this time for the blessings of the messianic kingdom. During the Millennium, God will fulfil all outstanding covenant promises and prophecies, and in the same realm where both the first Adam and seventy nations once failed, the Last Adam will successfully rule over Israel and the nations to the glory of God. Israelology, the doctrine of Israel’s past, present and future, is the missing link in Biblical and Systematic Theology.

    West Nile Virus (WNV) is endemic in Israel and was responsible for several outbreaks in the past 16 years. The aim of the present study was to investigate the spatial distribution of WNV acute infections from an outbreak that occurred in 2015 in Israel and report the molecular and geographic characterization of WNV isolates from human cases and mosquito pools obtained during this outbreak. Using a geographical layer comprising 51 continuous areas of Israel, the number of WNV infection cases per 100 000 people in each area and the locations of WNV-infected mosquitoes in 2015 were analysed. Sequencing and phylogenetic analyses followed by geographic localization were performed on 13 WNV human isolates and 19 WNV-infected mosquito pools. Substantial geographical variation in the prevalence of acute WNV in patients in Israel was found and an overall correlation with WNV-infected mosquitoes. All human patients sequenced were infected only with the Mediterranean subtype of WNV Lineage 1 and resided primarily in the coastal regions in central Israel. In contrast, mosquitoes were infected with both the Mediterranean and Eastern European subtypes of WNV lineage 1; however, only the Mediterranean subtype was found in mosquitoes from the coastal region in central Israel. These results demonstrate differential geographic dispersion in Israel of the two WNV subtypes and may also point to a differential pattern of human infections. As a geographical bridge between Europe, Asia and Africa, analysis of WNV circulation in humans and mosquitoes in Israel provides information relevant to WNV infections in Eurasia.

    Total chromium levels were determined in 38 detergents and 12 bleaches on the market in Israel (45 locally produced, 5 imported). The samples were analyzed by Zeeman-corrected graphite furnace atomic absorption spectrophotometry. Chromium levels were higher than 5 ppm in 28 (56%) of the 50 products...... ppm, it is concluded that these consumer products may be the cause of the high incidence of chromium sensitivity in Israel....

    Based on field studies, museums collections and literature sources, the current knowledge of the tiger beetle fauna of Israel and adjacent lands is presented. In Israel eight species occur, one of them with two subspecies, while in the Sinai Peninsula nine species of tiger beetles are now known. In the combined regions seven genera from two tribes were found. The Rift Valley with six cicindelids species is the most specious region of Israel. Cylindera contorta valdenbergi and Cicindela javeti azari have localized distributions and should be considered regional endemics. A similarity analysis of the tiger beetles faunas of different regions of Israel and the Sinai Peninsula reveal two clusters of species. The first includes the Great Rift Valley and most parts of the Sinai Peninsula, and the second incorporates most regions of Israel together with Central Sinai Foothills. Five distinct adult phenological groups of tiger beetles can be distinguished in these two clusters: active all-year (three species), spring-fall (five species), summer (two species), spring-summer (one species) and spring (one species). The likely origins of the tiger beetle fauna of this area are presented. An annotated list and illustrated identification key of the Cicindelinae of Israel and adjacent lands are provided.

    Multilocus microsatellite typing (MLMT) was used to investigate the genetic variation among 44 Israeli and Palestinian strains of L. infantum isolated from infected dogs and human cases to determine their population structure and to compare them with strains isolated from different European countries. Most of the Israeli and Palestinian strains had their own individual MLMT profiles; a few shared the same profile. A Bayesian model-based approach and phylogenetic reconstructions based on genetic distances inferred two main populations that were significantly different from the European strains: population A, containing 16 strains from places in the West Bank and 11 strains from central Israel;and population B, containing 7 strains from northern Israel, 9 from central Israel, and one Palestinian strain from the Jenin District.Geographically distributed sub-populations were detected within population B. These results demonstrate similar disease dynamics in Israel and the Palestinian Authority. The re-emergence of VL in the case of population A is more likely owing to increased dog and human contact with sylvatic cycles of parasitic infection rather than to recent introduction from the older foci of northern Israel. The latter scenario could be true for population B found in few foci of Central Israel. (c) 2009 Elsevier Masson SAS. All rights reserved.

    The incidence rates for premalignant lesions in Jewish women in Israel are similar to those observed in Western countries, but the incidence of cervical cancer in Israel is low; this discrepancy is not yet clearly understood. Because of the low incidence of cervical cancer in Israel, it was decided to base cervical cancer prevention on opportunistic screening: every woman from the ages of 35-54 years can have a Pap test smear free of charge every 3 years. Over the last decade 12.2% of the women population had an annual Pap test. From 36 to 50% of women who attended the Clalit Health Maintenance Organization (HMO) and the Maccabi HMO, the two largest HMOs in Israel, did so. There were also discrepancies between women of different socio-economic status (SES): Israel Society of Obstetrics and Gynecology recommends continuing cytologic screening in vaccinated women as recommended for the general population. This article forms part of a regional report entitled "Comprehensive Control of HPV Infections and Related Diseases in Israel" Vaccine Volume 31, Supplement 8, 2013.

    Israel has a long history of West Nile virus (WNV) morbidity, and the rate of detection of WNV in mosquitoes has been high since 2000. The aim of this study was to integrate several WNV datasets in order to gain an insight into the geographical distribution of WNV in Israel. Three choropleth maps were generated showing WNV human morbidity, WNV prevalence in mosquitoes, and the results of a nationwide serological survey, based on the division of Israel into 15 sub-districts. The maps show a high endemicity of WNV in Israel. In respect to the morbidity map, the population residing in the central part of the country and in Arava Region is at higher risk of developing the disease than the population of the rest of Israel. Interestingly, high prevalence rates of both WNV serology and WNV-infected mosquitoes were detected in Arava Region, but lower prevalence rates were detected in most areas of the coastal region, suggesting that other factors might also be important in the development of symptomatic WNV infections. These results underline the high prevalence of WNV in Israel and point to specific risk areas for WNV infections across the country. Copyright © 2017 The Author(s). Published by Elsevier Ltd..

    Three independent sets of measurements of the stopping power of solid elemental targets for alpha particles were previously analyzed in terms of basic Bethe-Bloch theory with the low velocity projectile-z 3 correction term included. These data for Al, Si, Ni, Ge, Se, Y, Ag and Au have now been analyzed with the Bloch projectile-z 4 term and a revised projectile-z 3 term incorporated in the Bethe-Bloch formula, the projectile-z 3 revision having been effected by variation of the single free parameter of the projectile-z 3 effect formalism. The value of this parameter, fixed at 1.8 in previous studies, which counteracts inclusion of the projectile-z 4 term is 1.3 +- 0.1 for all target elements except Si. (orig.)

    Cigarette smoking is a major cause of health disparities. We aimed to determine social characteristics associated with smoking status and age at smoking initiation in the ethnically-diverse population of Israel. This is a cross-sectional survey, based on data collected during 2010 by the Israel Bureau of Statistics, in a representative nationwide sample of 7,524 adults (≥20 years). Information collected by personal interviews included a broad set of demographic and socio-economic characteristics and detailed information on smoking habits. Associations between social characteristics and smoking habits were tested in multivariable regression models. Current smoking was more frequent among men than among women (30.9 % vs. 16.8 %; p  rate of unemployment, lower income, possession of fewer material assets, difficulty to meet living expenses) and lower educational level were significantly associated with current smoking among men but not among women. Family status other than being married was associated with higher likelihood of being a current smoker, while being traditional or observant was associated with a lower likelihood of ever smoking among both gender groups. Arab minority men and male immigrants from the former Soviet Union countries were more frequently current smokers than Israeli-born Jewish men [adjusted odds ratio (95 % confidence interval): 1.53 (1.22, 1.93) and 1.37 (1.01-1.87), respectively]. Compared to Israeli-born men, the age at smoking initiation was younger among male immigrants, and older among Arab minority men [adjusted hazard ratio (95 % confidence interval): 1.360 (1.165-1.586), and 0.849 (0.749-0.962), respectively]. While the prevalence of current smoking was lower in younger birth cohorts, the age at smoking initiation among ever-smokers declined as well. Among several subgroups within the Israeli population the smoking uptake is high, e.g. Arab men, men who are less affluent, who have lower educational level, and male immigrants

    A six-month research period is a mandatory part of the residency training program in most basic specialties in Israel and is named: the "basic science period". This is the only period in an Israeli physician's medical career which is dedicated strictly to research, accentuating the importance of medical research to the quality of training and level of medicine in Israel. From another point of view, one may argue that in an era of shortage of physicians on the one hand and the dizzying rate of growth in medical knowledge on the other hand, every moment spent training in residency is precious, therefore, making the decision of whether to dedicate six months for research becomes ever more relevant. This question is currently raised for discussion once again by the Scientific Council of the Israeli Medical Association. The Scientific Council lately issued a call for comments sent to all Israeli physicians, asking their opinion on several key questions regarding basic science research. Learning the public's opinion will serve as a background for discussion. A total of 380 physicians responded to the call and specified their standpoint on the subject, among them heads of departments, units and clinics, senior physicians and residents. The findings pointed to strong support in maintaining the research period as part of residency training due to its importance to medical training and medicine, although half the respondents supported the use of various alternative formats for research together with the existing format. Those alternative format suggestions will be thoroughly reviewed. A smaller group of respondents supported allowing residents a choice between two tracks--with or without a research period, and only a few were in favor of canceling the research requirement altogether. The writers maintain that the "basic science period" of research during residency training is vital and its contribution to the high level of specialists and high level of medicine requires its

    Supervision and inspection of medical facilities are among the responsibilities of the Ministry of Health (MOH) anchored in the "Public Health Act 1940". In order to implement the law, the General Medical Division of the MOH began the process of auditing hospitals and private surgical clinics prior to considering the reissue of their license. The audit aimed to implement the law, activate supervision on general hospitals and private surgical clinics, provide feed-back to the audited institution and upgrade quality assurance, regulate medical activities according to the activities elaborated in the license and recommend the license renewal. Prior to the audits, 20 areas of activity were chosen for inspection. For each activity a check list was developed as a tool for inspection. Each area was inspected during a 4-5 hour visit by a MOH expert, accompanied by the local service manager in the institution under inspection. A comprehensive report, summarizing the findings was sent to the medical institute, requesting correction in those areas where improvements were needed. Recommendation for license renewal was sent to the Director of Licensing Division Ministry of Health. Between June 2003 and July 2006, 91 structured audits took place. A total of 47 general hospitals and 24 private surgical clinics were visited at least once. Most general hospitals were found abiding, functioning according to the required standards and eligible for license renewal. Licenses of institutions that complied with the standards determined by the audit teams, were renewed. Two private hospitals in central Israel, that were given an overall poor evaluation, were issued with a temporary license and subsequently re-audited 4 times over the next two years. Generally, the standards in private surgical clinics were lower than those found in general public hospitals. In one clinic the license was not renewed, and in another an order was issued to cease surgical procedures requiring general

    We report on atmospheric electrical measurements conducted at the Wise Observatory in Mitzpe-Ramon, Israel (30°35‧N, 34°45‧E) during a large dust storm that occurred over the Eastern Mediterranean region on 10-11 February 2015. The dust was transported from the Sahara, Egypt and the Sinai Peninsula ahead of an approaching Cyprus low. Satellite images show the dust plume covering the Negev desert and Southern Israel and moving north. The concentrations of PM10 particles measured by the air-quality monitoring network of the Israeli Ministry of the Environment in Beer-Sheba reached values > 450 μg m- 3 and the AOT from the AERONET station in Sde-Boker was 1.5 on February 10th. The gradual intensification of the event reached peak concentrations on February 11th of over 1200 μg m- 3 and an AOT of 1.8. Continuous measurements of the fair weather vertical electric field (Ez) and vertical current density (Jz) were conducted at the Wise Observatory with 1 minute temporal resolution. Meteorological data was also recorded at the site. As the dust was advected over the observatory, very large fluctuations in the electrical parameters were registered. From the onset of the dust storm, the Ez values changed between + 1000 and + 8000 V m- 1 while the current density fluctuated between - 10 pA m2 and + 20 pA m2, both on time-scales of a few minutes. These values are significant departures from the average fair-weather values measured at the site, which are ~- 200 V m- 1 and ~ 2 pA m2. The disturbed episodes lasted for several hours on February 10th and the 11th and coincided with local meteorological conditions related to the wind speed and direction, which carried large amounts of dust particles over our observation station. We interpret the rapid changes as caused by the transport of electrically charged dust, carrying an excess of negative charge at lower altitudes.

    In this work we calculate the mass spectra of charmonium for 1 P ,…,4 P states of 0++ and 1++, for 1 S ,…,5 S states of 0-+, and for 1 S ,…,4 D states of 1- along with the two-photon decay widths of the ground and first excited states of 0++ quarkonia for the process O++→γ γ in the framework of a QCD-motivated Bethe-Salpeter equation (BSE). In this 4 ×4 BSE framework, the coupled Salpeter equations are first shown to decouple for the confining part of the interaction (under the heavy-quark approximation) and are analytically solved, and later the one-gluon-exchange interaction is perturbatively incorporated, leading to mass spectral equations for various quarkonia. The analytic forms of wave functions obtained are used for the calculation of the two-photon decay widths of χc 0. Our results are in reasonable agreement with data (where available) and other models.

    The vast amount of archaeological data and information that is systematically accumulated in the Israel Antiquities Authority database, has not yet been transformed into a tool for heritage management, i.e. accessible knowledge of the sites' cultural significance and risk assessment that is needed to support wise decision making regarding its future. As a response, a pilot project for developing an inventory for the archaeological heritage management was launched. A basic ESRI ArcGIS Online system was developed as a prototype, following the categories recommended in international standards for documentation. Five field surveys implementing the GIS system were conducted to examine different aspects and workflows: ancient synagogues in the Galilee, sites at risk, mosaics in Tel Shiqmona, the ancient settlement of Huqoq and sites included in The National Master Plan for Forests and Afforestation. The pilot project revealed the main gaps in knowledge and the critical faults in the working procedures. In spite of the systems' technological limitations, the results were convincing enough to promote a multidisciplinary discussion about the need for integration of significance and risk assessment in the working processes of the organization.

  18. Tsunamis induced by submarine slumpings off the coast of Israel

    1975-07-01

    The historical description of tsunamis or seismic sea waves at the coast of Israel is related. It is found that such an event was followed more often by a sea recession than by a shore flooding. A quantitative evaluation based on data of actual submarine scars, which may have been caused by slumpings on the continental slope, is carried out. It was found that the slumping of a mass 6 km long, 2 km wide and about 50 m deep would cause the formation of a shock-induced solitary wave of about 10 m in height at the edge of the continental slope. The accompanying draw-down of the sea level at the coast would last about 1/2 - 1.5 hours and lay the sea floor bare for a distance of about 1/2 - 1.5 km in agreement with some of the historical descriptions. Though possibly occurring only once or twice in a millenium, earthquake-induced slumpings may constitute a danger to nuclear power plants. (B.G.)

    Full Text Available Modern medicine makes it possible to transplant not only kidneys but any solid organs from one human body to another. Although it is the ideal to harvest organs from a brain-dead person, a kidney or a part of the liver or lung can be transplanted from a living donor to a patient. The majority of countries where organ transplants are performed have a dire need for transplantable organs as the current systems of organ procurement are not obtaining a sufficient amount of transplantable organs. Today’s cruel reality is that many patients are dying while waiting for a transplant. Few nations are able to meet the organ demand through their domestic transplant systems and there is a constant debate about ethical ways of procuring organs for transplantation purposes. This article will scrutinise the Israeli system of organ procurement and it will be compared with the current system of organ donation in South Africa (SA in order to indicate whether SA could possibly, or should, follow the example of Israel to improve its acute donor organ shortage.

    Date palm (Phoenix dactylifera) and pecan (Carya illinoensis) trees are commonly planted in Israel for fruit, for shade, or as ornamental plants. Pollen grains of both species are allergenic; however, the extent of exposure to such pollen and the incidence of allergic response have not been studied here. We therefore investigated skin-test responses to pollen extracts of 12 varieties of palm and 9 of pecan in 705 allergic patients living in 3 cities and 19 rural settlements. Sensitivity to the pollen extracts of both species was much higher among residents of rural than of urban communities. Moreover, there was a definite relationship between the abundance of these trees in a region and the incidence of skin responders to their pollen. Sensitivity was frequent in settlements rich in these 2 species, such as those with nearby commercial date or pecan plantations. In general, sensitivity to date pollen extracts was lower than to pecan. However, differences in skin responses to pollen extracts of various clones were substantiated. Air sampling revealed that pollen pollution decreased considerably with distance from the trees. At approximately 100 m from a source concentrations of airborne pollen were low. Since planting of male palm and pecan trees in population centers would increase pollen pollution, it should be avoided.
