    Full Text Available The Josef Gallery, located in the central Bohemia region of the Czech Republic was first excavated in 1981 as an exploration complex for the potential mining of gold. In 2007, the gallery was substantially reconstructed to house the Josef Underground Educational Facility (Josef UEF, which subsequently became an autonomous workplace under the direction of the Czech Technical University in Prague. At the beginning of 2010, the UEF was renamed the Josef Regional Underground Research Centre (Josef URC which, along with the extensive underground complex, features modern above-ground facilities. One of the most important roles of this research center is to provide practical in-situ instruction in the fields of geotechnical engineering, geology, geochemistry, radiochemistry and radioecology. The training of future experts in this authentic underground setting involves the participation of several other Czech universities and numerous experienced specialists from outside the academic sphere. The IAEA (International Atomic Energy Agency has added the Josef URC to its prestigious list of international training canters involved in the “Training in and Demonstration of Waste Disposal Technologies in Underground Research Facilities – A Network of Centers of Excellence” project.

    2013-01-01

    It was with great sadness that we learned of the death of our colleague Josef Hofmann. During his 35-year career at CERN, Josef made important contributions to many CERN projects. He passed away in December 2012.     In May 1964, Josef left Siemens in Germany to join CERN’s Nuclear Physics Apparatus (NPA) division, where he worked on electro-magnet models and developed equipment for high-power experiments. According to his group leader, B. Kuiper, Josef made “an exceptionally effective contribution to the Serpukhov installation under very difficult circumstances”. This installation was a collaboration between CERN and the USSR in the early 1970s, which involved designing and building a fast ejection system for a proton synchrotron based in Serpukhov. In 1972, Josef began work on the SPS magnet system. He moved on to work in the SPS North and then the SPS West experimental areas in 1981 and, finally, in the SL (SPS+LEP) department. In the mid-1990s, Jo...

    Full Text Available Resumen Josef Svoboda (1920-2002, fue escenógrafo, arquitecto y director artístico de la Linterna Mágica en Praga. Es difícil encontrar en los últimos cien años un escenógrafo que haya aportado tanto al mundo de la escena por su desbordante capacidad creativa. Siempre estuvo dispuesto a resolver problemas con planteamientos novedosos de diseño introduciendo para ello aportaciones tecno­lógicas del momento. Indagó con imaginación sobre otros elementos escenográficos que no fuesen los clásicos diseños basados en corpóreos arquitectónicos, bastidores, etc., pero que determinaban de igual modo un espacio escénico. Amplió la espacialidad en la escena adjudicando capacidades al sonido y a la luz para conseguir una corporeidad psicológica al servicio de la dramaturgia y la estética. Introdujo en el diseño de sus escenografías imágenes con múltiples perspectivas que se percibían con un solo golpe de vista. También utilizó a los espectadores haciéndoles participes de lo que estaba sucediendo en escena. Creó los sistemas de polivisión y poliecrán, que combinaban el teatro y el ballet. Es responsable de la famosa cortina de luz blanca creada por unos focos diseñados por él y que reciben su nombre. Las proyecciones sobre espejos, técnica difícil de manejar en escena, fue otra de las innovaciones que Svoboda manejó magistralmente en sus escenografías. Palabras clave: Diseño escenográfico, Josef Svoboda, poliecrán, focos Svo­boda, cortina de luz, proyecciones sobre espejo permeable, Laterna Magika. Abstract Josef Svoboda (1920-2002 has been a scenographer, architect and artistic director of the Magic Lantern in Prague.

    In this paper we analyze entanglement classification of extended Greenberger-Horne-Zeilinger-symmetric states $\\rho^{ES}$, which is parametrized by four real parameters $x$, $y_1$, $y_2$ and $y_3$. The condition for separable states of $\\rho^{ES}$ is analytically derived. The higher classes such as bi-separable, W, and Greenberger-Horne-Zeilinger classes are roughly classified by making use of the class-specific optimal witnesses or map from the extended Greenberger-Horne-Zeilinger symmetry t...

  10. Multisetting Greenberger-Horne-Zeilinger paradoxes

    Tang, Weidong; Yu, Sixia; Oh, C. H.

    2017-01-01

    The Greenberger-Horne-Zeilinger (GHZ) paradox provides an all-versus-nothing test for the quantum nonlocality. In most of the GHZ paradoxes known so far each observer is allowed to measure only two alternative observables. Here we present a general construction for GHZ paradoxes in which each observer measures more than two observables given that the system is prepared in the n -qudit GHZ state. By doing so we are able to construct a multisetting GHZ paradox for the n -qubit GHZ state, with n being arbitrary, which is genuine n -partite; i.e., no GHZ paradox exists when restricted to a subset of a number of observers for a given set of Mermin observables. Our result fills up the gap of the absence of a genuine GHZ paradox for the GHZ state of an even number of qubits, especially the four-qubit GHZ state as used in GHZ's original proposal.

    Schemes to generate Greenberger-Horne-Zeilinger (GHZ) and cluster states of three atoms are proposed in a two-mode cavity. The advantages of the schemes are their robustness against decoherence due to spontaneous emission of the excited states and decay of the cavity modes. Moreover, the schemes can be generalized to generate N-atom entangled states

    We generalize Greenberger-Horne-Zeilinger (GHZ) nonlocality to every even-dimensional and odd-partite system. For the purpose we employ concurrent observables that are incompatible and nevertheless have a common eigenstate. It is remarkable that a tripartite system can exhibit the genuinely high-dimensional GHZ nonlocality

    A superconducting magnet has been constructed for the determination of excited-state g-factors of fission products through perturbed angular correlation measurements at the separator JOSEF. The system contains a channel at room temperature which allows the rapid transport of radioactive samples with a tape device into the centre of the magnet. Thus experiments on the γ radiation from short-lived β/sup -/ decaying nuclei are possible. The coils of the magnet have been built by Oxford Instruments Ltd while the cryostat has been designed and manufactured in the central workshop of the Kernforschungsanlage Julich. The maximum field strength is 6.54 T at a current of 59 A and the homogeneity is better than one percent for an area with a radius of 0.5 cm at the centre of the magnet. The liquid helium consumption is only 0.3 1/h. The magnet has been used for the determination of the g-factors of the 2/sub 1//sup +/ states in /sup 102/Mo and /sup 104/Mo

  16. General proof of the Greenberger-Horne-Zeilinger theorem

    International Nuclear Information System (INIS)

    2004-01-01

    It is proved that all states of three spin-(1/2) particles exhibiting an 'all versus nothing' contradiction between quantum mechanics and the local realism of Einstein, Podolsky, and Rosen are exactly the Greenberger-Horne-Zeilinger (GHZ) states and the states obtained from them by local unitary transformations. The proof is obtained by showing that there are at most four elements (except for a different sign) in a set of mutually commuting nonlocal spin observables in the three-qubit system and using the certain algebraic properties that Pauli's matrices satisfy. We show that only does such a set of four nonlocal spin observables present a Greenberger-Horne-Zeilinger-Mermin-like argument. This also reveals the equivalence between the GHZ theorem and maximal violation of the Bell inequality

  17. Optimal detection of entanglement in Greenberger-Horne-Zeilinger states

    Kay, Alastair

    2011-01-01

    We present a broad class of N-qubit Greenberger-Horne-Zeilinger (GHZ)-diagonal states such that nonpositivity under the partial transpose operation is necessary and sufficient for the presence of entanglement, including many naturally arising instances such as dephased GHZ states. Furthermore, our proof directly leads to an entanglement witness which saturates this bound. The witness is applied to thermal GHZ states to prove that the entanglement can be extremely robust to system imperfections.

  18. Franz Josef Land: extreme northern outpost for Arctic fishes

    Full Text Available The remote Franz Josef Land (FJL Archipelago is the most northerly land in Eurasia and its fish fauna, particularly in nearshore habitats, has been poorly studied. An interdisciplinary expedition to FJL in summer 2013 used scuba, seines, and plankton nets to comprehensively study the nearshore fish fauna of the archipelago. We present some of the first underwater images for many of these species in their natural habitats. In addition, deep water drop cameras were deployed between 32 and 392 m to document the fish fauna and their associated habitats at deeper depths. Due to its high latitude (79°–82°N, extensive ice cover, and low water temperatures (<0 °C much of the year, the fish diversity at FJL is low compared to other areas of the Barents Sea. Sixteen species of fishes from seven families were documented on the expedition, including two species previously unknown to the region. One Greenland shark, Somniosus microcephalus (Somniosidae, ca. 2 m in length, was recorded by drop camera near Hayes Island at 211 m, and Esipov’s pout, Gymnelus esipovi (Zoarcidae, was collected at Wilton Island at 15 m in a kelp forest. Including the tape-body pout, Gymnelus taeniatus, described earlier from the sub-littoral zone of Kuhn Island, 17 fish species are now known from FJL’s nearshore waters. Species endemic to the Arctic accounted for 75% of the nearshore species observed, followed by species with wider ranges. A total of 43 species from 15 families are known from FJL with the majority of the records from offshore trawl surveys between 110 and 620 m. Resident species have mainly high Arctic distributions, while transient species visit the archipelago to feed (e.g., Greenland shark, and others are brought by currents as larvae and later migrate to spawn grounds in the south (e.g., Atlantic cod Gadus morhua, Capelin Mallotus villosus, Beaked redfish Sebastes mentella. Another species group includes warmer-water fishes that are rare waifs (e

    The generation of Greenberger-Horne-Zeilinger (GHZ) states is a crucial problem in quantum information. We derive general conditions for obtaining GHZ states as eigenstates of a Hamiltonian. We find that a necessary condition for an n-qubit GHZ state to be a nondegenerate eigenstate of a Hamiltonian is the presence of m-qubit couplings with m≥[(n+1)/2]. Moreover, we introduce a Hamiltonian with a GHZ eigenstate and derive sufficient conditions for the removal of the degeneracy.

    Along with the vast progress in experimental quantum technologies there is an increasing demand for the quantification of entanglement between three or more quantum systems. Theory still does not provide adequate tools for this purpose. We provide a simple procedure to quantify Greenberger-Horne-Zeilinger-type multipartite entanglement in arbitrary three-qubit states. The method is based on the recently introduced GHZ symmetry and exact results for the states which are invariant under this symmetry, and generally gives a good lower bound to the three-tangle. A generalization both to more parties and to higher-dimensional systems is possible.

    2017-06-01

    We study the problem of converting a product of Greenberger-Horne-Zeilinger (GHZ) states shared by subsets of several parties in an arbitrary way into GHZ states shared by every party. Such a state can be described by a hypergraph on the parties as vertices and with each hyperedge corresponding to a GHZ state shared among the parties incident with it. Our result is that if SLOCC transformations are allowed, then the best asymptotic rate is the minimum of bipartite log-ranks of the initial state, which in turn equals the minimum cut of the hypergraph. This generalizes a result by Strassen on the asymptotic subrank of the matrix multiplication tensor.

    We study the generation of Greenberger-Horne-Zeilinger (GHZ) states of three path-encoded photons. Inspired by the seminal work of Bouwmeester et al. [Phys. Rev. Lett. 82, 1345 (1999), 10.1103/PhysRevLett.82.1345] on polarization-entangled GHZ states, we find a corresponding path representation for the photon states of an optical circuit, identify the elements required for the state generation, and propose a possible implementation of our strategy. Besides the practical advantage of employing an integrated system that can be fabricated with proven lithographic techniques, our example suggests that it is possible to enhance the generation efficiency by using microring resonators.

    The simulation of quantum correlations with finite nonlocal resources, such as classical communication, gives a natural way to quantify their nonlocality. While multipartite nonlocal correlations appear to be useful resources, very little is known on how to simulate multipartite quantum correlations. We present a protocol that reproduces tripartite Greenberger-Horne-Zeilinger correlations with bounded communication: 3 bits in total turn out to be sufficient to simulate all equatorial Von Neumann measurements on the tripartite Greenberger-Horne-Zeilinger state.

    A quantum steganography communication scheme via Greenberger-Horne-Zeilinger GHZ 4 state is constructed to investigate the possibility of remotely transferred hidden information. Moreover, the multipartite entangled states are become a hectic topic due to its important applications and deep effects on aspects of quantum information. Then, the scheme consists of sharing the correlation of four particle GHZ 4 states between the legitimate users. After insuring the security of the quantum channel, they begin to hide the secret information in the cover of message. Comparing the scheme with the previous quantum steganographies, capacity and imperceptibility of hidden message are good. The security of the present scheme against many attacks is also discussed.

    2012-01-01

    Along with the vast progress in experimental quantum technologies there is an increasing demand for the quantification of entanglement between three or more quantum systems. Theory still does not provide adequate tools for this purpose. The objective is, besides the quest for exact results, to develop operational methods that allow for efficient entanglement quantification. Here we put forward an analytical approach that serves both these goals. We provide a simple procedure to quantify Greenberger-Horne-Zeilinger-type multipartite entanglement in arbitrary three-qubit states. For two qubits this method is equivalent to Wootters' seminal result for the concurrence. It establishes a close link between entanglement quantification and entanglement detection by witnesses, and can be generalised both to higher dimensions and to more than three parties.

  20. Greenberger-Horne-Zeilinger paradoxes from qudit graph states.

    Tang, Weidong; Yu, Sixia; Oh, C H

    2013-03-08

    One fascinating way of revealing quantum nonlocality is the all-versus-nothing test due to Greenberger, Horne, and Zeilinger (GHZ) known as the GHZ paradox. So far genuine multipartite and multilevel GHZ paradoxes are known to exist only in systems containing an odd number of particles. Here we shall construct GHZ paradoxes for an arbitrary number (greater than 3) of particles with the help of qudit graph states on a special kind of graphs, called GHZ graphs. Furthermore, based on the GHZ paradox arising from a GHZ graph, we derive a Bell inequality with two d-outcome observables for each observer, whose maximal violation attained by the corresponding graph state, and a Kochen-Specker inequality testing the quantum contextuality in a state-independent fashion.

  1. Irreducible multiqutrit correlations in Greenberger-Horne-Zeilinger-type states

    Zhang, Fu-Lin; Chen, Jing-Ling

    2011-01-01

    Following the idea of the continuity approach by D. L. Zhou [Phys. Rev. Lett. 101, 180505 (2008)], we obtain the degrees of irreducible multiparty correlations in two families of n-qutrit Greenberger-Horne-Zeilinger-type states. For the pure states in one of the families, the irreducible 2-party, n-party, and (n-m)-party (0< m< n-2) correlations are nonzero, which is different from the n-qubit case. We also derive the correlation distributions in the n-qutrit maximal slice state, which can be uniquely determined by its (n-1)-qutrit-reduced density matrices among pure states. It is proved that there is no irreducible n-qutrit correlation in the maximal slice state. This enlightens us to give a discussion about how to characterize the pure states with irreducible n-party correlation in arbitrarily high-dimensional systems by the way of the continuity approach.

    A new experimentally feasible anonymous survey protocol with authentication using Greenberger-Horne-Zeilinger (GHZ) entangled states is proposed. In this protocol, a chief executive officer (CEO) of a firm or company is trying to find out the effect of a possible action. In order to prepare a fair voting, the CEO would like to make an anonymous survey and is also interested in the total action for the whole company and he doesn't want to have a partial estimate for each department. In our proposal, there are two voters, Alice and Bob, voting on a question with a response of either "yes" or "no" and a tallyman, whose responsibility is to determine whether they have cast the same vote or not. In the proposed protocol the total response of the voters is calculated without revealing the actual votes of the voters.

  3. Greenberger-Horne-Zeilinger nonlocality for continuous-variable systems

    2002-01-01

    As a development of our previous work, this paper is concerned with the Greenberger-Horne-Zeilinger (GHZ) nonlocality for continuous-variable cases. The discussion is based on the introduction of a pseudospin operator, which has the same algebra as the Pauli operator, for each of the N modes of a light field. Then the Bell-Clauser-Horne-Shimony-Holt inequality is presented for the N modes, each of which has a continuous degree of freedom. Following Mermin's argument, it is demonstrated that for N-mode parity-entangled GHZ states (in an infinite-dimensional Hilbert space) of the light field, the contradictions between quantum mechanics and local realism grow exponentially with N, similarly to the usual N-spin cases

  4. Una sentencia justa para Josef K.: sobre El proceso de Kafka

    2001-12-01

    Full Text Available At the beginning of The Process the narrator says that Josef K. was arrested one morning «having done nothing serious». Nevertheless there are very few critics that have taken this sentence to the letter. As Josef K. is executed at last, it must be supposed that the character should have commited some sort of crime. Though it has been speculated a lot about which this crime could be, it has been impossible to reach a firm decision. What this way of reading the story shows is that is tremendously difficult to conceive the idea of a world in which it would be possible to arrest and execute innocent people with no justification at all. But this is precisely the basis of the fiction world imagined by Kafka, who through The Process prefigured the terror lived all over Europe dominated by totalitarism.

    Al comienzo de El proceso el narrador afirma que Josef K. fue arrestado una mañana «sin que hubiera hecho nada malo». Son muy pocos, sin embargo, los críticos que se han tomado esta frase al pie de la letra. Puesto que Josef K. es finalmente ejecutado, se supone más bien que el personaje habría cometido algún tipo de falta. Aunque se ha especulado mucho sobre cuál pudiera ser esa falta, no se ha podido llegar a una firme decisión al respecto. Lo que este modo de leer el relato revela es que resulta muy difícil concebir la idea de un mundo en el que fuera posible arrestar y ejecutar a personas inocentes, sin ninguna clase de justificación. Pero en esto consiste, precisamente, el mundo de ficción imaginado por Kafka, quien prefiguró así en El proceso el terror vivido en la Europa dominada por el totalitarismo.

    Full Text Available Results obtained by simulating snow characteristics with a numerical model of surface heat and moisture exchange SPONSOR are presented. The numerical experiments are carried out for Franz Josef Land with typical Arctic climate conditions. The blizzard evaporation parameter is shown to have great influence on snow depth on territories with high wind speed. This parameter significantly improves the simulation quality of the numerical model. Some discrepancies between evaluated and observed snow depth values can be explained by inaccuracies in precipitation measurements (at least in certain cases and errors in calculations of incoming radiation, mostly due to low accuracy in the cloudiness observations.

  6. Polarization entanglement purification for concatenated Greenberger-Horne-Zeilinger state

    Science.gov (United States)

    Zhou, Lan; Sheng, Yu-Bo

    2017-10-01

    Entanglement purification plays a fundamental role in long-distance quantum communication. In the paper, we put forward the first polarization entanglement purification protocol (EPP) for one type of nonlocal logic-qubit entanglement, i.e., concatenated Greenberger-Horne-Zeilinger (C-GHZ) state, resorting to the photon-atom interaction in low-quality (Q) cavity. In contrast to existing EPPs, this protocol can purify the bit-flip error and phase-flip error in both physic and logic level. Instead of measuring the photons directly, this protocol only requires to measure the atom states to judge whether the protocol is successful. In this way, the purified logic entangled states can be preserved for further application. Moreover, it makes this EPP repeatable so as to obtain a higher fidelity of logic entangled states. As the logic-qubit entanglement utilizes the quantum error correction (QEC) codes, which has an inherent stability against noise and decoherence, this EPP combined with the QEC codes may provide a double protection for the entanglement from the channel noise and may have potential applications in long-distance quantum communication.

  8. Fault-tolerant Greenberger-Horne-Zeilinger paradox based on non-Abelian anyons.

    Science.gov (United States)

    Deng, Dong-Ling; Wu, Chunfeng; Chen, Jing-Ling; Oh, C H

    2010-08-06

    We propose a scheme to test the Greenberger-Horne-Zeilinger paradox based on braidings of non-Abelian anyons, which are exotic quasiparticle excitations of topological states of matter. Because topological ordered states are robust against local perturbations, this scheme is in some sense "fault-tolerant" and might close the detection inefficiency loophole problem in previous experimental tests of the Greenberger-Horne-Zeilinger paradox. In turn, the construction of the Greenberger-Horne-Zeilinger paradox reveals the nonlocal property of non-Abelian anyons. Our results indicate that the non-Abelian fractional statistics is a pure quantum effect and cannot be described by local realistic theories. Finally, we present a possible experimental implementation of the scheme based on the anyonic interferometry technologies.

  9. Tripartite entanglement versus tripartite nonlocality in three-qubit Greenberger-Horne-Zeilinger-class states.

    Science.gov (United States)

    Ghose, S; Sinclair, N; Debnath, S; Rungta, P; Stock, R

    2009-06-26

    We analyze the relationship between tripartite entanglement and genuine tripartite nonlocality for three-qubit pure states in the Greenberger-Horne-Zeilinger class. We consider a family of states known as the generalized Greenberger-Horne-Zeilinger states and derive an analytical expression relating the three-tangle, which quantifies tripartite entanglement, to the Svetlichny inequality, which is a Bell-type inequality that is violated only when all three qubits are nonlocally correlated. We show that states with three-tangle less than 1/2 do not violate the Svetlichny inequality. On the other hand, a set of states known as the maximal slice states does violate the Svetlichny inequality, and exactly analogous to the two-qubit case, the amount of violation is directly related to the degree of tripartite entanglement. We discuss further interesting properties of the generalized Greenberger-Horne-Zeilinger and maximal slice states.

    2010-01-01

    The effects of distributing entanglement through the amplitude damping channel or the phase damping channel on the teleportation of a single-qubit state via the Greenberger–Horne–Zeilinger state and the W state are discussed. It is found that the average fidelity of teleportation depends on the type and rate of the damping in the channel. For the one-qubit affected case, the Greenberger–Horne–Zeilinger state is as robust as the W state, i.e., the same quantum information is preserved through teleportation. For the two-qubit affected case, the W state is more robust when the entanglement is distributed via the amplitude damping channel; if the entanglement is distributed via the phase damping channel, the W state is more robust when the noisy parameter is small while the Greenberger–Horne–Zeilinger state becomes more robust when it is large. For the three-qubit affected case, the Greenberger–Horne–Zeilinger state is more robust than the W state. (general)

    In this paper, we propose a scheme for the remote preparation of a three-particle Greenberger-Horne-Zeilinger class state by a two-particle entangled state and a three-particle entangled state. It is shown that, by this scheme, only two classical bits and one two-particle projective measurement are enough for such preparation.

Following Car and Parrinello [Phys. Rev. Lett. 55, 2471 (1985)], the electronic density is treated as a dynamical variable. The electronic densities are verified against a multi-ion Thomas-Fermi algorithm due to Parker [Phys. Rev. A 38, 2205 (1988)]. As an initial application, the effect of electronic polarization in enhancing ionic diffusion in strongly coupled plasmas is demonstrated

    2018-03-01

    We consider a particle dressed with boundary gravitons in three-dimensional Minkowski space. The existence of BMS transformations implies that the particle’s wavefunction picks up a Berry phase when subjected to changes of reference frames that trace a closed path in the asymptotic symmetry group. We evaluate this phase and show that, for BMS superrotations, it provides a gravitational generalization of Thomas precession. In principle, such phases are observable signatures of asymptotic symmetries.

    2015-12-01

    Full Text Available In 1912 Josef Strzygowski founded the ‘Section for East Asian Art History’ at the University of Vienna, which attracted many students who would continue their careers in museums and at universities and thus established East Asian art history as an academic field. This paper examines these early art historical engagements with East Asian art: First, I discuss the role of East Asian art in Strzygowski’s agenda of broadening art history’s geographical scope beyond Europe and in his argument about the dominance of ‘Nordic’ artistic traditions in Europe and in Asia. Secondly, I introduce the work of two early students at the ‘Section for East Asian Art History’ in Vienna, Karl With and Alfred Salmony. Their respective approaches to East Asian art exemplify a range of methodological concerns of their time, from stylistic narratives, the concept of ars una, comparative frameworks, to ideas about cultural or national ‘purity’ in the arts, and an interest in cross-cultural adaption and transformation of motifs and symbolism.

    Full Text Available Literary texts about historical disasters tend to offer moral, political, or scientific interpretations of the occurrence that go well beyond the immediate experience of a catastrophe. They are, almost exclusively, written by people who did not in fact experience the catastrophic event. Survivor accounts, by contrast, typically do not have literary qualities. Phi Phi Island, the Austrian writer and essayist Josef Haslinger's literary report on how he and his family lived through the tsunami of 2004, is an exception. Point of departure for Haslinger's narrative is his inability to rejoice in the fact that he is alive. Carefully crafted and beautifully realized, his text combines the reconstruction of the events with reflections about how one can tell such a story in the first place. This essay analyzes Haslinger's strategies for coming to terms with the coincidence of survival, observing that the very personal nature of the report stands in noticeable contrast to the writer's commitment to political commentary in his other works.

    A multiparty simultaneous quantum identity authentication protocol based on Greenberger–Horne–Zeilinger (GHZ) states is proposed. The multi-user can be authenticated by a trusted third party (TTP) simultaneously. Compared with the scheme proposed recently (Wang et al 2006 Chin. Phys.

    The theory of a four photon interference experiment is investigated for the testing of the Greenberger-Horne-Zeilinger (GHZ) theorem. The strong correlation in the GHZ theorem is due to the multi-particle Einstein-Podolsky-Rosen type entangled quantum state. We present the theory to construct the four photon EPR state for space-time variables. The four photon nonlocal quantum interference effect itself is also of great interest. (orig.)

    By solving analytically a master equation in the Lindblad form, we study quantum teleportation of the one-qubit state under the influence of different surrounding environments, and compared the robustness between Greenberger-Horne-Zeilinger (GHZ) and W states in terms of their teleportation capacity. The results revealed that when subject to zero temperature environment, the GHZ state is always more robust than the W state, while the reverse situation occurs when the channel is subject to infinite temperature or dephasing environment.

    Based on the input-output relation of the cavity and the Faraday Rotation mechanism, we propose a scheme for generating the n-atom Greenberger-Horne-Zeilinger state. In the scheme, the n-atom trapped respectively in n spatially separate cavities would be entangled with the photons going through the atom-cavity system. The successful probabilities of our protocol approach unity in the ideal case. What is more, no requirement for separately addressing further lowers experimental difficulties. (general)

    We have performed the first experimental tomographic reconstruction of a three-photon polarization state. Quantum state tomography is a powerful tool for fully describing the density matrix of a quantum system. We measured 64 three-photon polarization correlations and used a "maximum-likelihood" reconstruction method to reconstruct the Greenberger-Horne-Zeilinger state. The entanglement class has been characterized using an entanglement witness operator and the maximum predicted values for the Mermin inequality were extracted.

The first scheme for concentrating the nonmaximally entangled GHZ state is based on linear optical devices. The second scheme for concentrating the W class states can be applied to a wide variety of atomic state. Both of our schemes are not postselection ones and are within the current technologies.

    We investigate local contents in N-qubit generalized Greenberger-Horne-Zeilinger (GHZ) states. We suggest a decomposition for correlations in the GHZ states into a nonlocal and fully local part, and find a lower and upper bound on the local content. Our lower bound reproduces the previous result for N=2[V. Scarani, Phys. Rev. A 77, 042112 (2008)] and decreases rapidly with N.

    We present a new simple scheme for the preparation of Greenberger-Horne-Zeilinger maximally entangled states of two two-level atoms. The distinct feature of the effective Hamiltonian is that there is no energy exchange between the atoms and the cavity.. Thus the scheme is insensitive to the effect of cavity field and the atom radiation.This protocol may be realizable in the realm of current physical experiment.

    In this paper we propose a scheme for creating a three photons Greenberger-Horne-Zeilinger-type (GHZ) state using only linear optics elements and single-photon detectors. We furthermore generalize the scheme for producing any GHZ-like state of n photons. The input state of the scheme consists of a nonentangled state of n photons. Experimental aspects regarding the implementation of the scheme are presented. Finally, the role of such schemes in quantum information processing with photons is discussed

This scheme is based on N single photon Bell state measurements, which can be implemented non-locally. The success probability is 100% in principle and our scheme is feasible with current technology. All the advantages make our protocol meaningful and practical in quantum information processing. (general)

  20. Non-Markovianity Measure Based on Brukner-Zeilinger Invariant Information for Unital Quantum Dynamical Maps

    He, Zhi; Zhu, Lie-Qiang; Li, Li

    2017-03-01

    A non-Markovianity measure based on Brukner-Zeilinger invariant information to characterize non-Markovian effect of open systems undergoing unital dynamical maps is proposed. The method takes advantage of non-increasing property of the Brukner-Zeilinger invariant information under completely positive and trace-preserving unital maps. The simplicity of computing the Brukner-Zeilinger invariant information is the advantage of the proposed measure because of mainly depending on the purity of quantum state.

    A non-Markovianity measure based on Brukner–Zeilinger invariant information to characterize non-Markovian effect of open systems undergoing unital dynamical maps is proposed. The method takes advantage of non-increasing property of the Brukner–Zeilinger invariant information under completely positive and trace-preserving unital maps. The simplicity of computing the Brukner–Zeilinger invariant information is the advantage of the proposed measure because of mainly depending on the purity of quantum state. The measure effectively captures the characteristics of non-Markovianity of unital dynamical maps. As some concrete application, we consider two typical non-Markovian noise channels, i.e., the phase damping channel and the random unitary channel to show the sensitivity of the proposed measure. By investigation, we find that the conditions of detecting the non-Markovianity for the phase damping channel are consistent with the results of existing measures for non-Markovianity, i.e., information flow, divisibility and quantum mutual information. However, for the random unitary channel non-Markovian conditions are same to that of the information flow, but is different from that of the divisibility and quantum mutual information. (paper)

    An Act of Parliament in 1540 uniting the barbers and surgeons to form the Barber-Surgeons' Company represented an important foundation stone towards better surgery in England. Thomas Vicary, who played a pivotal role in promoting this union, was a leading surgeon in London in the middle of the 16th century. While Vicary made no direct contribution to surgical knowledge, he should be remembered primarily as one who contributed much towards the early organization and teaching of surgery and to the consequent benefits that flowed from this improvement.

  3. Digging up the Past: Space, Time, and Memory in Josef Haslinger’s "Fiona und Ferdinand"

    Full Text Available Josef Haslinger’s story "Fiona und Ferdinand" (2006 revolves around a disclosed secret in its narrator’s childhood hometown, which implicates two (deceased village elders in a decades-old rape and murder mystery long blamed on two anonymous “Russian soldiers.” The discovery of two partial skeletons locked in a bedroom trunk awakens the narrator’s memory: years before as a child, he unearthed the same skeletons after first spying a finger bone buried in a stream. The identification of the bones is central in determining the perpetrators of the rape/murder, but no one -- and in particular the narrator’s mother -- seems interested in hearing the testimony of the crime’s lone eyewitness, now an aged woman. Instead, the revelation evokes a collective effort to willfully impede any investigation into the truth, presumably as a means to maintain the town’s dual pretenses of order and respectability. "Fiona und Ferdinand" emphasizes Haslinger’s preoccupation with the Austrian failure to confront its own past, specifically via families as fundamental units of transmission and memory. In this analysis of the text, I explore Haslinger’s treatment of space, time, and memory in several ways. First, I examine how his notion of “officially sanctioned memory” intersects with a landscape that contains past and present alike. Second, I discuss how bodies, either the violated female body or the rotted skeletons Fiona and Ferdinand, are emblems that raise discussions of space, gender, and memory. Last, I consider collective memory and how it enables processes of forgetting. The reluctance to “dig up the past” is thematized in "Fiona und Ferdinand" using devices common throughout Haslinger’s oeuvre, and this paper will analyze the story through the lens of Haslinger-as-archaeologist, exploring how families, and the memories they possess, are both the key to truth and the foil to its revelation.

    Full Text Available Hanns-Josef Ortheil's early novels Fermer , 1979 and Hecke , 1983 have male protagonists who search for self-identity in the West Germany of the 1980s. In the process, they discover that they are profoundly influenced by the lives and experiences of their parents, particularly as these lives were shaped during and by the Hitler regime. In Fermer , the 19-year old protagonist rebels against this society by going AWOL. Yet in his geographical flight and intellectual analyses he realizes his deep emotional bonds with the expectations and behavior of the parent generation. Recognition of these bonds is only the first step on a Iong and painful road toward personally independent and politically responsible adulthood. An exploration of the key concepts of order and Geborgenheit (being protected reveals the deep-seated ambiguities in the postwar mentality of the parent generation as it is trying to instill these sentiments in their successors. The 30-year old protagonist of Hecke pieces together his mother's traumatized life during and after the Hitler regime in order to understand her emotionally stultifying hold on him. He comes to understand the manipulative power of her suffering and realizes that he must shed the burden of her displaced needs if he hopes to attain a conscious, mature self-identity. The use and the manipulation of language and its silences are the prime target of the narrator's efforts to penetrate the "protective hedges" of untold stories. Both novels conclude with the protagonists' intellectual insights into their psychological and socially conditioned make-up, but they do not—yet—carry these insights into action.

    Nonextensive Thomas-Fermi model was father investigated in the following directions: Heavy atom in strong magnetic field. following Shivamoggi work on the extension of Kadomtsev equation we applied nonextensive formalism to father generalize TF model for the very strong magnetic fields (of order 10e12 G). The generalized TF equation and the binding energy of atom were calculated which contain a new nonextensive term dominating the classical one. The binding energy of a heavy atom was also evaluated. Thomas-Fermi equations in N dimensions which is technically the same as in Shivamoggi (1998) ,but behavior is different and in interesting 2 D case nonextesivity prevents from becoming linear ODE as in classical case. Effect of nonextensivity on dielectrical screening reveals itself in the reduction of the envelope radius. It was shown that nonextesivity in each case is responsible for new term dominating classical thermal correction term by order of magnitude, which is vanishing in a limit q->1. Therefore it appears that nonextensive term is ubiquitous for a wide range of systems and father work is needed to understand the origin of it.

    We propose an efficient scheme to build an arbitrary multipartite Greenberger-Horne-Zeilinger state and discriminate all the universal Greenberger-Horne-Zeilinger states using parity measurement based on dipole-induced transparency in a cavity-waveguide system. A prominent advantage is that initial entangled states remain after nondetective identification and they can be used for successive tasks. We analyze the performance and possible errors of the required single-qubit rotations and emphasize that the scheme is reliable and can satisfy the current experimental technology

    A novel approach to quantum cryptography to be called NQKD, networking quantum key distribution, has been developed for secure quantum communication schemes on the basis of the complementary relations of entanglement Greenberger-Horne-Zeilinger (GHZ) triplet states. One scheme distributes the private key among legal participants in a probabilistic manner, while another transmits the deterministic message with some certainty. Some decoy photons are employed for preventing a potential eavesdropper from attacking quantum channels. The present schemes are efficient as there exists an elegant method for key distributions. The security of the proposed schemes is exactly guaranteed by the entanglement of the GHZ quantum system, which is illustrated in security analysis.

    Quantum Fisher information of a parameter characterizes the sensitivity of the state with respect to changes of the parameter. In this article, we study the quantum Fisher information of a state with respect to SU(2) rotations under three decoherence channels: the amplitude-damping, phase-damping, and depolarizing channels. The initial state is chosen to be a Greenberg-Horne-Zeilinger state of which the phase sensitivity can achieve the Heisenberg limit. By using the Kraus operator representation, the quantum Fisher information is obtained analytically. We observe the decay and sudden change of the quantum Fisher information in all three channels.

    Lorentz transformation of the three-qubit Greenberger-Horne-Zeilinger (GHZ) state is studied. Also we obtain the relativistic spin joint measurement for the transformed state. Using these results it is shown that Bell's inequality is maximally violated for the three-qubit GHZ state in the relativistic regime. For ultrarelativistic particles we obtain the critical value for boost speed, which Bell's inequality is not violated for velocities smaller than this value. We also show that in the ultrarelativistic limit Bell's inequality is maximally violated for the GHZ state

    2013-01-01

    We propose a scheme to generate a Greenberger—Horn—Zeilinger (GHZ) state of four atoms trapped in a two-mode optical cavity via an adiabatic passage. The scheme is robust against moderate fluctuations of the experimental parameters. Numerical calculations show that the excited probabilities of both the cavity modes and the atoms are tiny and depend on the pulse peaks of the classical laser fields. For certain decoherence due to the atomic spontaneous emission and the cavity decay, there exits a range of pulse peaks to get a high fidelity. (general)

    Motivated by the complementary relations of the Greenherger-Horne-Zeilinger (GHZ) entangled triplet-particle states, a novel way of realizing quantum distributed ballot scheme is proposed. The ballot information is encoded by local operations performed on the particles of entangled GHZ triplet states, which ensures the security of the present scheme. In order to guarantee the security of this scheme, the checking phase is designed in detail on the basis of the entangled GHZ triplet state. The analysis shows the security of the proposed scheme.

    We propose a scheme to generate a four-particle Greenberger-Horne-Zeilinger (GHZ) state of distant atoms that are trapped separately in leaky cavities. This scheme uses cavity decay to inject photons into a setup of optical devices that consist of a symmetric series of beam splitters and photon detectors. Photon detection on the output modes of the beam splitters projects the atom-cavity-system state onto the GHZ state. It is briefly pointed out that this scheme can be extended to generate GHZ states of 4m atoms

Several devices are designed and a two-mode quantum nondemolition detection is introduced to obtain the desired state. It is worth noting that the states which have entanglement in both polarization and spatial degrees of freedom are created in one of the designed setups. The method described in the present scheme can create a large number of three-photon GHZ states in principle. We also discuss an approach to generate the desired GHZ state in the presence of channel noise.

    The Greenberger-Horne-Zeilinger (GHZ) theorem exhibits an 'all versus nothing' contradiction between Ernstein, Podelsky, and Rosen's local realism and quantum mechanics by using a maximally entangled state of three qubits. However, it is shown in this paper that no extension of GHZ's proof is possible for any entangled state of two qubits, including Bell states. The proof is obtained by showing the fact that there are no more than three distinct elements (except for a different sign) in a set of mutually commuting nonlocal spin observables of two qubits. This also leads to a generic setup of the Kochen-Specker theorem for the two-qubit system

    The concatenated Greenberger-Horne-Zeilinger (C-GHZ) state is a new type of multipartite entangled state, which has potential application in future quantum information. In this paper, we propose a protocol of constructing arbitrary C-GHZ entangled state approximatively. Different from previous protocols, each logic qubit is encoded in the coherent state. This protocol is based on the linear optics, which is feasible in experimental technology. This protocol may be useful in quantum information based on the C-GHZ state.

    We consider a system composed of a single-atom-trapped cavity (A) and a remote two-atom-trapped cavity (B) which are connected by an optical fibre. It is shown that a shared Greenberger-Horne-Zeilinger (GHZ) state of the three atoms can be deterministically generated by controlling the time of interaction or via the adiabatic passage based on this system. The influence of various decoherence processes such as spontaneous emission and photon loss on the fidelity is also investigated. It is found that our schemes can be realized with high fidelity even when these decoherence processes are considered.

    As one of the most promising candidates for implementing quantum computers, superconducting qubits (SQs) are adopted for fast generating the Greenberger–Horne–Zeilinger (GHZ) state by using invariants-based shortcuts. Three SQs are separated and connected by two coplanar waveguide resonators (CPWRs) capacitively. The complicated system is skillfully simplified to a three-state system, and a GHZ state among three SQs is fast generated with a very high fidelity and simple driving pulses. Numerical simulations indicate the scheme is insensitive to parameter deviations. Besides, the robustness of the scheme against decoherence is discussed in detail. (paper)

    We present an efficient scheme for the preparing and purifying of the four-photon Greenberger–Horne–Zeilinger (GHZ) state based on linear optics and postselection. First, we describe how to create a four-photon GHZ state in both polarization and spatial degrees of freedom from two pairs. Moreover, in the presence of depolarization noise our scheme is capable of purifying the desired state. In the regime of weak nonlinearity we design an indirect photon number-resolving detection to distinguish two states of the two pairs. At last, a fourfold coincidence detector click indicates the creation of a polarization-entangled four-photon GHZ state. (paper)

    We calculate the analytic expression for geometric measure of entanglement for arbitrary superposition of two N-qubit canonical orthonormal Greenberger-Horne-Zeilinger (GHZ) states and the same for two W states. In the course of characterizing all kinds of nonclassical correlations, an explicit formula for quantum discord (via relative entropy) for the former class of states has been presented. Contrary to the GHZ state, the closest separable state to the W state is not classical. Therefore, in this case, the discord is different from the relative entropy of entanglement. We conjecture that the discord for the N-qubit W state is log 2 N.

The authors include also a self-interaction of the scalar meson field and the Coulomb repulsion of the protons. The parameters of the model are constrained by the average nuclear properties. The Thomas-Fermi equations are solved numerically for finite, stable nuclei. The particular case of 208 82 Pb is considered in more detail. (Auth.)

    Georg Josef Camel (1661-1706) went to the Spanish colony of the Philippine Islands as a Jesuit lay brother in 1687, and he remained there until his death. Throughout his time in the Philippines, Camel collected examples of the flora and fauna, which he drew and described in detail. This paper offers an overview of his life, his publications and the Camel manuscripts, drawings and specimens that are preserved among the Sloane Manuscripts in the British Library and in the Sloane Herbarium at the Natural History Museum, London. It also discusses Camel's links and exchanges with scientifically minded plant collectors and botanists in London, Madras and Batavia. Among those with whom Camel corresponded were John Ray, James Petiver, and the Dutch physician Willem Ten Rhijne.

    Medial moraines form important pathways for sediment transportation in valley glaciers. Despite the existence of well-defined medial moraines on several glaciers in the New Zealand Southern Alps, medial moraines there have hitherto escaped attention. The evolving morphology and debris content of medial moraines on Franz Josef Glacier and Fox Glacier on the western flank of the Southern Alps is the focus of this study. These temperate maritime glaciers exhibit accumulation zones of multiple basins that feed narrow tongues flowing down steep valleys and terminate 400 m above sea level. The medial moraines at both glaciers become very prominent in the lower ablation zones, where the medial moraines widen, and develop steeper flanks coeval with an increase in relative relief. Medial moraine growth appears somewhat self-limiting in that relief and slope angle increase eventually lead to transport of debris away from the medial moraine by mass-movement-related processes. Despite similarities in overall morphologies, a key contrast in medial moraine formation exists between the two glaciers. At Fox Glacier, the medial moraine consists of angular rockfall-derived debris, folded to varying degrees along flow-parallel axes throughout the tongue. The debris originates above the ELA, coalesces at flow-unit boundaries, and takes a medium/high level transport pathway before subsequently emerging at point-sources aligned with gently dipping fold hinges near the snout. In contrast at Franz Josef Glacier, the medial moraine emerges farther down-glacier immediately below a prominent rock knob. Clasts show a mix of angular to rounded shapes representing high level transport and subglacially transported materials, the latter facies possibly also elevated by supraglacial routing of subglacial meltwater. Our observations confirm that a variety of different debris sources, transport pathways, and structural glaciological processes can interact to form medial moraines within New Zealand

    In blind quantum computation (BQC) protocol, the quantum computability of servers are complicated and powerful, while the clients are not. It is still a challenge for clients to delegate quantum computation to servers and keep the clients' inputs, outputs and algorithms private. Unfortunately, quantum channel noise is unavoidable in the practical transmission. In this paper, a novel BQC protocol based on maximally entangled Greenberger-Horne-Zeilinger (GHZ) states is proposed which doesn't need a trusted center. The protocol includes a client and two servers, where the client only needs to own quantum channels with two servers who have full-advantage quantum computers. Two servers perform entanglement concentration used to remove the noise, where the success probability can almost reach 100% in theory. But they learn nothing in the process of concentration because of the no-signaling principle, so this BQC protocol is secure and feasible.

    Concatenated Greenberger-Horne-Zeilinger (C-GHZ) state, which encodes many physical qubits in a logic qubit will have important applications in both quantum communication and computation. In this paper, we will describe an entanglement concentration protocol (ECP) for electronic C-GHZ state, by exploiting the electronic polarization beam splitters (PBSs) and charge detection. This protocol has several advantages. First, the parties do not need to know the exact coefficients of the initial less-entangled C-GHZ state, which makes this protocol feasible. Second, with the help of charge detection, the distilled maximally entangled C-GHZ state can be remained for future application. Third, this protocol can be repeated to obtain a higher success probability. We hope that this protocol can be useful in future quantum computation based on electrons.

  7. Generation of the quadripartite Greenberger–Horne–Zeilinger entangled state in quantum beat lasers

    2013-01-01

    In this letter, a scheme is presented to obtain quadripartite Greenberger–Horne–Zeilinger (GHZ) entanglement via quantum beats in a four-level diamond configuration atomic system. When the top and the ground states are initially prepared in a coherent superposition, the four quantized fields coupling with four dipole-allowed transitions can be correlated with each other by using a strong microwave field to drive the dipole-forbidden transition. It is the combined effect of atomic coherence-controlled correlated-spontaneous emission and double quantum beats that results in the quadripartite GHZ-type entanglement. Our numerical results show that the quadripartite entanglement, which can be controlled effectively by varying the amplitude and phase of the microwave field, occurs in a very wide parameter range. In addition, using input–output theory, we find that the output quadripartite entanglement is robust against thermal fluctuations, which may be useful for long-distance quantum communications.

  8. Entanglement of three-qubit Greenberger-Horne-Zeilinger-symmetric states.

    2012-01-13

    The first characterization of mixed-state entanglement was achieved for two-qubit states in Werner's seminal work [Phys. Rev. A 40, 4277 (1989)]. A physically important extension concerns mixtures of a pure entangled state [such as the Greenberger-Horne-Zeilinger (GHZ) state] and the unpolarized state. These mixed states serve as benchmark for the robustness of multipartite entanglement. They share the symmetries of the GHZ state. We call such states GHZ symmetric. Here we give a complete description of the entanglement in the family of three-qubit GHZ-symmetric states and, in particular, of the three-qubit generalized Werner states. Our method relies on the appropriate parametrization of the states and on the invariance of entanglement properties under general local operations. An application is the definition of a symmetrization witness for the entanglement class of arbitrary three-qubit states.

    We delve a little deeper into the construction of shortcuts to adiabatic passage for three-level systems by iterative interaction picture (multiple Schrödinger dynamics). As an application example, we use the deduced iterative based shortcuts to rapidly generate the Greenberger-Horne-Zeilinger (GHZ) state in a three-atom system with the help of quantum Zeno dynamics. Numerical simulation shows the dynamics designed by the iterative picture method is physically feasible and the shortcut scheme performs much better than that using the conventional adiabatic passage techniques. Also, the influences of various decoherence processes are discussed by numerical simulation and the results prove that the scheme is fast and robust against decoherence and operational imperfection.

    The paradox of Greenberger-Horne-Zeilinger (GHZ) disproves directly the concept of EPR elements of reality, based on the EPR correlations, in an all-versus-nothing way. A three-qubit experimental demonstration of the GHZ paradox was achieved nearly 20 years ago, followed by demonstrations for more qubits. Still, the GHZ contradictions underlying the tests can be reduced to a three-qubit one. We show an irreducible four-qubit GHZ paradox, and report its experimental demonstration. The bound of a three-setting-per-party Bell-GHZ inequality is violated by 7 σ . The fidelity of the GHZ state was around 81 % , and an entanglement witness reveals a violation of the separability threshold by 19 σ .

    Quantum nonlocality gives us deeper insight into quantum physics. In addition, quantum nonlocality has been further recognized as an essential resource for device-independent quantum information processing in recent years. Most experiments of nonlocality are performed using a photonic system. However, until now, photonic experiments of nonlocality have involved at most four photons. Here, for the first time, we experimentally demonstrate the six-photon quantum nonlocality in an all-versus-nothing manner based on a high-fidelity (88.4%) six-photon Greenberger-Horne-Zeilinger state. Our experiment pushes multiphoton nonlocality studies forward to the six-photon region and might provide a larger photonic system for device-independent quantum information protocols.

  12. Multiqubit W states lead to stronger nonclassicality than Greenberger-Horne-Zeilinger states

    The N-qubit states of the W class, for N>10, lead to more robust (against noise admixture) violations of local realism, than the Greenberger-Horne-Zeilinger (GHZ) states. These violations are most pronounced for correlations for a pair of qubits, conditioned on specific measurement results for the remaining N-2 qubits. The considerations provide us with a qualitative difference between the W state and GHZ state in the situation when they are separately sent via depolarizing channels. For sufficiently high amount of noise in the depolarizing channel, the GHZ states cannot produce a distillable state between two qubits, whereas the W states can still produce a distillable state in a similar situation

    2011-01-01

    The nonclassical properties of the noisy three-qubit Greenberger-Horne-Zeilinger (GHZ) states, ρ v =v|GHZ> v is nonclassical for the parameter range 1/2< v≤1. It has been posed whether additional settings would allow to lower the threshold visibility. Here we report on Bell inequalities giving a threshold value smaller than v=1/2. This rules out the possibility of a local hidden variable model in the limit of v=1/2. In particular, the lowest threshold visibility we found is v=0.496 057, attainable with 5x5x5 settings, whereas the most economical one in number of settings corresponds to 3x3x4 settings. The method which enabled us to obtain these results, and in particular the about 10 000 tight Bell inequalities giving v<1/2, are also discussed in detail.

  14. Generation of an arbitrary concatenated Greenberger-Horne-Zeilinger state with single photons

    2017-02-01

    The concatenated Greenberger-Horne-Zeilinger (C-GHZ) state is a new kind of logic-qubit entangled state, which may have extensive applications in future quantum communication. In this letter, we propose a protocol for constructing an arbitrary C-GHZ state with single photons. We exploit the cross-Kerr nonlinearity for this purpose. This protocol has some advantages over previous protocols. First, it only requires two kinds of cross-Kerr nonlinearities to generate single phase shifts  ±θ. Second, it is not necessary to use sophisticated m-photon Toffoli gates. Third, this protocol is deterministic and can be used to generate an arbitrary C-GHZ state. This protocol may be useful in future quantum information processing based on the C-GHZ state.

  15. Quadripartite cluster and Greenberger–Horne–Zeilinger entangled light via cascade interactions with separated atomic ensembles

    International Nuclear Information System (INIS)

    Li Xing; Hu Xiangming

    2012-01-01

    It has been known that two-mode entangled light can possibly be generated by employing near-resonant interaction with an ensemble of two-level atoms. The responsible mechanism is the absorption of two photons from the strong driving field and the emission of two new photons into the cavity field. Here, we generalize such a mechanism to three separated atomic ensembles and establish cascade interactions for four nondegenerate fields. It is shown that the quadripartite cluster and Greenberger–Horne–Zeilinger entangled states occur for continuous variables. The advantage of the present scheme for the multipartite entanglement lies in that the coupling strengths are much larger due to the near resonances than for far-off-resonance-based parametric processes.

    2006-01-01

    We generalize the Greenberger-Horne-Zeilinger nonlocality without inequalities argument to cover the case of arbitrary mixed statistical operators associated to three-qubits quantum systems. More precisely, we determine the radius of a ball (in the trace distance topology) surrounding the pure GHZ state and containing arbitrary mixed statistical operators which cannot be described by any local and realistic hidden variable model and which are, as a consequence, noncompletely separable. As a practical application, we focus on certain one-parameter classes of mixed states which are commonly considered in the experimental realization of the original GHZ argument and which result from imperfect preparations of the pure GHZ state. In these cases we determine for which values of the parameter measuring the noise a nonlocality argument can still be exhibited, despite the mixedness of the considered states. Moreover, the effect of the imperfect nature of measurement processes is discussed

    Some mixed states composed of only Greenberger-Horne-Zeilinger (GHZ) states can be expressed in terms of only W states. This fact implies that such states have vanishing three-tangle. One of such rank-3 states, Π GHZ , is explicitly presented in this Rapid Communication. These results are used to compute analytically the three-tangle of a rank-4 mixed state σ composed of four GHZ states. This analysis with considering Bloch sphere S 16 of d=4 qudit system allows us to derive the hyperpolyhedron. It is shown that the states in this hyperpolyhedron have vanishing three-tangle. Computing the one-tangles for Π GHZ and σ, we prove the monogamy inequality explicitly. Making use of the fact that the three-tangle of Π GHZ is zero, we try to explain why the W class in the whole mixed states is not of measure zero contrary to the case of pure states.

  18. Pipe failure probability - the Thomas paper revisited

    International Nuclear Information System (INIS)

    Lydell, B.O.Y.

    2000-01-01

    Almost twenty years ago, in Volume 2 of Reliability Engineering (the predecessor of Reliability Engineering and System Safety), a paper by H. M. Thomas of Rolls Royce and Associates Ltd. presented a generalized approach to the estimation of piping and vessel failure probability. The 'Thomas-approach' used insights from actual failure statistics to calculate the probability of leakage and conditional probability of rupture given leakage. It was intended for practitioners without access to data on the service experience with piping and piping system components. This article revisits the Thomas paper by drawing on insights from development of a new database on piping failures in commercial nuclear power plants worldwide (SKI-PIPE). Partially sponsored by the Swedish Nuclear Power Inspectorate (SKI), the R and D leading up to this note was performed during 1994-1999. Motivated by data requirements of reliability analysis and probabilistic safety assessment (PSA), the new database supports statistical analysis of piping failure data. Against the background of this database development program, the article reviews the applicability of the 'Thomas approach' in applied risk and reliability analysis. It addresses the question whether a new and expanded database on the service experience with piping systems would alter the original piping reliability correlation as suggested by H. M. Thomas

    A proof of Bell's theorem without inequalities valid for both inequivalent classes of three-qubit entangled states under local operations assisted by classical communication, namely Greenberger-Horne-Zeilinger (GHZ) and W, is described. This proof leads to a Bell inequality that allows more conclusive tests of Bell's theorem for three-qubit systems. Another Bell inequality involving both tri- and bipartite correlations is introduced which illustrates the different violations of local realism exhibited by the GHZ and W states

    In this Brief Report we investigate the time evolution of entanglement in two-mode Bose-Einstein condensates (BEC's) with various parameters of the scattering lengths of interatoms collisions, Josephson coupling strength, and initial states. The degree of entanglement increases by strengthening the tunnel coupling and keeping the balance of the collision interaction. In the latter stage we show that the two-mode BEC's can be used for preparing the Greenberger-Home-Zeilinger state

    We present the latest capabilities added to the Co-Registration of Optically Sensed Images and Correlation (COSI-Corr) software, which aim at analyzing time-series of stereoscopic imagery to document 3D variations of the ground surface. We review the processing chain and present the new and improved modules for satellite pushbroom imagery, in particular the N-image bundle block adjustment to jointly optimize the viewing geometry of multiple acquisitions, the improved multi-scale image matching based on Semi-Global Matching (SGM) to extract high resolution topography, and the triangulation of multi-temporal disparity maps to derive 3D ground motion. In particular, processes are optimized to run on a cluster computing environment. This new suite of algorithms is applied to the study of Worldview stereo imagery above the Franz Josef, Fox, and Tasman Glaciers, New Zealand, acquired on 01/30/2013, 02/09/2013, and 02/28/2013. We derive high resolution (1m post-spacing) maps of ice flow in three dimensions, where ice velocities of up to 4 m/day are recorded. Images were collected in early summer during a dry and sunny period, which followed two weeks of unsettled weather with several heavy rainfall events across the Southern Alps. The 3D tracking of ice flow highlights the surface response of the glaciers to changes in effective pressure at the ice-bedrock interface due to heavy rainfall, at an unprecedented spatial resolution.

    Two methods of applying relativistic corrections to the Thomas--Fermi atom are considered, and numerical calculations are discussed. Radial charge distributions calculated from a relativistic Thomas--Fermi equation agree in gross form with those from more complicated self-consistent calculations. Energy eigenvalues for mercury, as determined from the relativistic Thomas--Fermi solution, are compared with other calculated and experimental values

  17. Building mechanical Greenberger-Horne-Zeilinger and cluster states by harnessing optomechanical quantum steerable correlations

    Greenberger-Horne-Zeilinger (GHZ) and cluster states are two typical kinds of multipartite entangled states and can respectively be used for realizing quantum networks and one-way computation. We propose a feasible scheme for generating Gaussian GHZ and cluster states of multiple mechanical oscillators by pulsed cavity optomechanics. In our scheme, each optomechanical cavity is driven by a blue-detuned pulse to establish quantum steerable correlations between the cavity output field and the mechanical oscillator, and the cavity outputs are combined at a beam-splitter array with given transmissivity and reflectivity for each beam splitter. We show that by harnessing the light-mechanical steerable correlations, the mechanical GHZ and cluster states can be realized via homodyne detection on the amplitude and phase quadratures of the output fields from the beam-splitter array. These achieved mechanical entangled states can be viewed as the output states of an effective mechanical beam-splitter array with the mechanical inputs prepared in squeezed states with the light-mechanical steering. The effects of detection efficiency and thermal noise on the achieved mechanical states are investigated. The present scheme does not require externally injected squeezing and it can also be applicable to other systems such as light-atomic-ensemble interface, apart from optomechanical systems.

    Single photons, manipulated using integrated linear optics, constitute a promising platform for universal quantum computation. A series of increasingly efficient proposals have shown linear-optical quantum computing to be formally scalable. However, existing schemes typically require extensive adaptive switching, which is experimentally challenging and noisy, thousands of photon sources per renormalized qubit, and/or large quantum memories for repeat-until-success strategies. Our work overcomes all these problems. We present a scheme to construct a cluster state universal for quantum computation, which uses no adaptive switching, no large memories, and which is at least an order of magnitude more resource efficient than previous passive schemes. Unlike previous proposals, it is constructed entirely from loss-detecting gates and offers a robustness to photon loss. Even without the use of an active loss-tolerant encoding, our scheme naturally tolerates a total loss rate ∼1.6% in the photons detected in the gates. This scheme uses only 3 Greenberger-Horne-Zeilinger states as a resource, together with a passive linear-optical network. We fully describe and model the iterative process of cluster generation, including photon loss and gate failure. This demonstrates that building a linear-optical quantum computer needs to be less challenging than previously thought.

    Inspired by a recent work [F. Reiter, D. Reeb, and A. S. Sørensen, Phys. Rev. Lett. 117, 040501 (2016), 10.1103/PhysRevLett.117.040501], we present a simplified proposal for dissipatively preparing a Greenberger-Horne-Zeilinger (GHZ) state of three Rydberg atoms in a cavity. The Z pumping is implemented under the action of the spontaneous emission of Λ -type atoms and the quantum Zeno dynamics induced by strong continuous coupling. In the meantime, a dissipative Rydberg pumping breaks up the stability of the state | GHZ+〉 in the process of Z pumping, making | GHZ-〉 the unique steady state of the system. Compared with the former scheme, the number of driving fields acting on atoms is greatly reduced and only a single-mode cavity is required. The numerical simulation of the full master equation reveals that a high fidelity ˜98 % can be obtained with the currently achievable parameters in the Rydberg-atom-cavity system.

    Multi-partite entangled states are important for developing studies of quantum networking and quantum computation. To date, the largest number of particles that have been successfully manipulated is 14 trapped ions. Yet in quantum information science, photons have particular advantages over other systems. In particular, they are more easily transportable qubits and are more robust against decoherence. Thus far, the largest number of photons to have been successfully manipulated in an experiment is six. Here we demonstrate, for the first time, an eight-photon Greenberger-Horne-Zeilinger state with a measured fidelity of 0.59±0.02, which proved the presence of genuine eight-partite entanglement. This is achieved by improving the photon detection efficiency to 25% with a 300-mW pump laser. With this state, we also demonstrate an eight-party quantum communication complexity scenario. This eight-photon entangled-state source may be useful in one-way quantum computation, quantum networks and other quantum information processing tasks.

    Bell's theorem states that certain statistical correlations predicted by quantum physics for measurements on two-particle systems cannot be understood within a realistic picture based on local properties of each individual particle-even if the two particles are separated by large distances. Einstein, Podolsky and Rosen first recognized the fundamental significance of these quantum correlations (termed 'entanglement' by Schrodinger) and the two-particle quantum predictions have found ever-increasing experimental support. A more striking conflict between quantum mechanical and local realistic predictions (for perfect correlations) has been discovered; but experimental verification has been difficult, as it requires entanglement between at least three particles. Here we report experimental confirmation of this conflict, using our recently developed method to observe three-photon entanglement, or 'Greenberger-Horne-Zeilinger' (GHZ) states. The results of three specific experiments, involving measurements of polarization correlations between three photons, lead to predictions for a fourth experiment; quantum physical predictions are mutually contradictory with expectations based on local realism. We find the results of the fourth experiment to be in agreement with the quantum prediction and in striking conflict with local realism.

    In this article, the robustness of tripartite Greenberger-Horne-Zeilinger (GHZ) and W states is investigated against Dzyaloshinskii-Moriya (i.e. DM) interaction. We consider a closed system of three qubits and an environmental qubit. The environmental qubit interacts with any one of the three qubits through DM interaction. The tripartite system is initially prepared in GHZ and W states, respectively. The composite four qubits system evolve with unitary dynamics. We detach the environmental qubit by tracing out from four qubits, and profound impact of DM interaction is studied on the initial entanglement of the system. As a result, we find that the bipartite partitions of W states suffer from entanglement sudden death (i.e. ESD), while tripartite entanglement does not. On the other hand, bipartite partitions and tripartite entanglement in GHZ states do not feel any influence of DM interaction. So, we find that GHZ states have robust character than W states. In this work, we consider generalised GHZ and W states, and three π is used as an entanglement measure. This study can be useful in quantum information processing where unwanted DM interaction takes place.

  4. Teleportation of continuous variable multimode Greeberger-Horne-Zeilinger entangled states

    2008-01-01

    Quantum teleportation protocols of continuous variable (CV) Greeberger-Horne-Zeilinger (GHZ) and Einstein-Podolsky-Rosen (EPR) entangled states are proposed, and are generalized to teleportation of arbitrary multimode GHZ entangled states described by Van Loock and Braunstein (2000 Phys. Rev. Lett. 84 3482). Each mode of a multimode entangled state is teleported using a CV EPR entangled pair and classical communication. The analytical expression of fidelity for the multimode Gaussian states which evaluates the teleportation quality is presented. The analytical results show that the fidelity is a function of both the squeezing parameter r, which characterizes the multimode entangled state to be teleported, and the channel parameter p, which characterizes the EPR pairs shared by Alice and Bob. The fidelity increases with increasing p, but decreases with increasing r, i.e., it is more difficult to teleport the more perfect multimode entangled states. The entanglement degree of the teleported multimode entangled states increases with increasing both r and p. In addition, the fact is proved that our teleportation protocol of EPR entangled states using parallel EPR pairs as quantum channels is the best case of the protocol using four-mode entangled states (Adhikari et al 2008 Phys. Rev. A 77 012337).

    We generalize the recently proposed Greenberger-Horne-Zeilinger tripartite protocol [A. Galiautdinov and J. M. Martinis, Phys. Rev. A 78, 010305(R) (2008)] to fully connected networks of weakly coupled qubits interacting by way of anisotropic Heisenberg exchange g(XX+YY)+g-tildeZZ. Our model differs from the more familiar Ising-Heisenberg chain in that here every qubit interacts with every other qubit in the circuit. The assumption of identical couplings on all qubit pairs allows an elegant proof of the protocol for arbitrary N. In order to further make contact with experiment, we study fidelity degradation due to coupling imperfections by numerically simulating the N=3 and 4 cases. Our simulations indicate that the best fidelity at unequal couplings is achieved when (a) the system is initially prepared in the uniform superposition state (similarly to how it is done in the ideal case) and (b) the entangling time and the final rotations on each of the qubits are appropriately adjusted.

    Complete sets of commuting observables (CSCOs) of the form Σ N =Π i=1 N σ iα i (α i =x,y,z) for an N-qubit system are extracted by a simple graphic approach. One can construct 2x3 N sets of operators, each set consisting of K N commuting Σ N , K N =2 N-1 +1 for even N, and 2 N-1 for odd N. Any N functional-independent operators among the K N operators may be adopted as a CSCO, whose simultaneous eigenstates (SEs) span an orthonormal basis of N-qubit space. These SEs have reduced density matrix of rank 2 and can be reduced to the Greenberger-Horne-Zeilinger (GHZ) state form of Eq. (2) in suitable representations. The all-versus-nothing demolition of the elements of reality holds for each basis of the form of Eq. (2) for N-qubit (N≥3) systems. Σ N may be considered as the infinitesimal operator of rotational operator R(α 1 ,α 2 ,...α N )=Π i=1 N exp[-iπσ iα i /2] , whose eigenvalue (signature) r=e -iπα , or signature exponent α, may be equivalently used for characterizing each basis.

    The authors further develop a recent new proof (by Greenberger, Horne, and Zeilinger - GHZ) that local deterministic hidden-variable theories are inconsistent with certain strict correlations predicted by quantum mechanics. First, they generalize GHZ's proof so that it applied to factorable stochastic theories in which apparatus hidden variables are casually relevant to measurement results, and theories in which the hidden variables evolve indeterministically prior to the particle-apparatus interactions. Then they adopt a more general measure-theoretic approach which requires that GHZ's argument be modified in order to produce a valid proof. Finally, they motivate the more general proof's assumptions in a somewhat different way from previous authors in order to strengthen the implications of the proof as much as possible. After developing GHZ's proof along these lines, they then consider the analogue, for their proof, of Bohr's reply to the EPR argument, and conclude (pace GHZ) that in at least one respect (viz, that of most concern to Bohr) the proof is no more powerful than Bell's. Nevertheless, they point out some new advantages of their proof over Bell's, and over other algebraic proofs of nonlocality. And they conclude by giving a modified version of their proof that, like Bell's does not rely on experimentally unrealizable strict correlations, but still leads to a testable quasi-algebraic locality inequality

    Restrictive conditions on the class of allowed physical theories are drawn from the assumption that the predictions of quantum theory are valid for an experiment of the kind proposed by Greenberger, Horne, and Zeilinger [in Bell's Theorem, Quantum Theory and Conceptions of the Universe, edited by M. Kafatos (Kluwer Academic, Dordrecht, 1989)]. It is shown that no theory can be compatible with the following four conditions. (1) The choices to be made by the three experimenters can be treated, in this context, as three independent free variables. (2) For each of the six possible local measurements under consideration, if that local measurement were to be performed, then exactly one of the alternative possible outcomes of this measurement must be selected as the actual outcome. (3) For each triad of measurements in a certain set of possible triads, if that triad were to be performed, then the corresponding triad of selected outcomes must satisfy the correlation condition predicted by quantum theory. (4) For each of the six possible local measurements, if that local measurement were to be performed, then the selected outcome must, according to the theory, be independent of which two experiments will later, in some frame of reference, be performed in the other two regions

    2009-01-01

    The article sets the cholera motif in Thomas Mann's famous novella Death in Venice against the historical context from which it partially originates. It is shown that this motif, while undoubtedly appropriated to serve Mann's own poetic ends, has a solid grounding in historical and autobiographical fact, thus blurring the boundaries between fact and fiction. The article illustrates the verifiable events of the outbreak of the Venetian cholera epidemic in May 1911, which Mann partly witnessed himself, during a holiday trip to Brioni and Venice, and partly heard and read about. It is established that Thomas Mann's account of the cholera in Venice in his novella is characterised by a rare and almost preternatural insightfulness into an otherwise murky affair that was marked by rumours, speculations and denials.

    Biological psychiatry in the early twentieth century was based on interrelated disciplines, such as neurology and experimental biology. Neuropsychiatrist Franz Josef Kallmann (1897-1965) was a product of this interdisciplinary background who showed an ability to adapt to different scientific contexts, first in the field of neuromorphology in Berlin, and later in New York. Nonetheless, having innovative ideas, as Kallmann did, could be an ambiguous advantage, since they could lead to incommensurable scientific views and marginalization in existing research programs. Kallmann followed his Dr. Med. degree (1919) with training periods at the Charité Medical School in Berlin under psychiatrist Karl Bonhoeffer (1868-1948). Subsequently, he collaborated with Ernst Ruedin (1874-1952), investigating sibling inheritance of schizophrenia and becoming a protagonist of genetic research on psychiatric conditions. In 1936, Kallmann was forced to immigrate to the USA where he published The Genetics of Schizophrenia (1938), based on data he had gathered from the district pathological institutes of Berlin's public health department. Kallmann resumed his role as an international player in biological psychiatry and genetics, becoming president (1952) of the American Society of Human Genetics and Director of the New York State Psychiatric Institute in 1955. While his work was well received by geneticists, the idea of genetic differences barely took hold in American psychiatry, largely because of émigré psychoanalysts who dominated American clinical psychiatry until the 1960s and established a philosophical direction in which genetics played no significant role, being regarded as dangerous in light of Nazi medical atrocities. After all, medical scientists in Nazi Germany had been among the social protagonists of racial hygiene which, under the aegis of Nazi philosophies, replaced medical genetics as the basis for the ideals and application of eugenics.

    We propose two schemes for generating Greenberger-Horne-Zeilinger and W states of three distant atoms. In the present schemes, the atoms are individually trapped in three spatially separated optical cavities coupled by two optical fibres. Performing an adiabatic passage along dark states, the population of cavities and fibres excited is negligible under certain conditions. In addition, the spontaneous decay of atoms is also efficiently suppressed based on our proposals. Furthermore, the discussion about the entanglement fidelity is given and we point out that our schemes work robustly with small fluctuations of experimental parameters. (general)

    Berry's approach on "transitionless quantum driving" shows how to set a Hamiltonian which drives the dynamics of a system along instantaneous eigenstates of a reference Hamiltonian to reproduce the same final result of an adiabatic process in a shorter time. In this paper, motivated by transitionless quantum driving, we construct shortcuts to adiabatic passage in a three-atom system to create the Greenberger-Horne-Zeilinger states with the help of quantum Zeno dynamics and of non-resonant lasers. The influence of various decoherence processes is discussed by numerical simulation and the result proves that the scheme is fast and robust against decoherence and operational imperfection.

    We propose an efficient scheme to generate multiqubit Greenberger-Horne-Zeilinger (GHZ) states by one-step quantum operation in a driven circuit quantum electrodynamics (QED) system. Our proposal is based on a unitary evolution exp[-iλS 2 x ], with S x being the collective spin operator in x direction and λ a controllable parameter, induced by driving the resonator. The quantum operation avoids resonator-field decay and may achieve the GHZ states with ideal success probability. The feasibility with the experimentally-demonstrated circuit QED system is also discussed. (general)

    We show a way to use an optical device set-up to generate the four-particle Greenberger-Horne-Zeilinger (GHZ) state of atoms, which are trapped separately in leaky cavities. Based on cavity decay, photons are transferred from the atom-cavity systems to a symmetric series of beam splitters and photon detectors. The events of photon detection on the output modes of the beam splitters project the state of the atom-cavity systems onto the GHZ state. It is briefly pointed out how this scheme can be extended to generate GHZ states of 4m atoms

    Twisted photons offer a high-dimensional Hilbert space with the degree of freedom of orbital angular momentum (OAM). Entanglement swapping allows entangling photons that never interact. We report in this paper the hybrid entanglement swapping from multiphoton spin-entangled states to multiphoton OAM entangled states with the aid of N-pair hybrid spin-OAM entangled photons. Our scheme provides a feasible method for creating the two-photon OAM Bell states (N=2) or multiphoton multidimensional OAM Greenberger-Horne-Zeilinger states (N≥3). We highlight the advantage of multiparticle, multidimensional entangled states in some applications of quantum information protocols.

    The existence and nature of tripartite entanglement of a noninteracting Fermi gas (NIFG) is investigated. Three classes of parametrized entanglement witnesses (EWs) are introduced with the aim of detecting genuine tripartite entanglement in the three-body reduced density matrix and discriminating between the presence of the two types of genuine tripartite entanglement, W/B and GHZ/W (the convex set of B states is comprised of mixed states of product and biseparable states; that of W states is comprised of mixed states of B states and W-type pure entangled states; and the GHZ (Greenberger-Horne-Zeilinger) set contains generic mixtures of any kind for a tripartite system). By choosing appropriate EW operators, the problem of finding GHZ and W EWs is reduced to linear programming. Specifically, we devise W EWs based on a spin-chain model with periodic boundary conditions, and we construct a class of parametrized GHZ EWs by linearly combining projection operators corresponding to all the different state-vector types arising for a three-fermion system. A third class of EWs is provided by a GHZ stabilizer operator capable of distinguishing W/B from GHZ/B entanglement, which is not possible with W EWs. Implementing these classes of EWs, it is found that all states containing genuine tripartite entanglement are of W type, and hence states containing GHZ/W genuine tripartite entanglement do not arise. Some genuine tripartite entangled states that have a positive partial transpose (PPT) with respect to some bipartition are detected. Finally, it is demonstrated that a NIFG does not exhibit 'pure'W/B genuine tripartite entanglement: three-party entanglement without any separable or biseparable admixture does not occur.

    Thomas Szasz's original critique of the concept of 'mental illness' is almost 50 years old. Over that half century Szasz has maintained a consistent campaign against the 'Therapeutic State', challenging the paternalism of coercive psychiatry and defending liberty and autonomy. Despite his widespread celebrity Szasz continues to be misread and misrepresented. In this paper we review some of Szasz's key ideas, in the light of Clarke's recent critique, setting this within the context of 'mental health nursing' and the problems in living affecting persons worldwide.

  6. Limitations of the Porter-Thomas distribution

    Data on the distribution of reduced partial neutron widths and on the distribution of total gamma decay widths disagree with the Porter-Thomas distribution (PTD) for reduced partial widths or with predictions of the statistical model. We recall why the disagreement is important: The PTD is a direct consequence of the orthogonal invariance of the Gaussian Orthogonal Ensemble (GOE) of random matrices. The disagreement is reviewed. Two possible causes for violation of orthogonal invariance of the GOE are discussed, and their consequences explored. The disagreement of the distribution of total gamma decay widths with theoretical predictions cannot be blamed on the statistical model.

    The Bo (meaning 'ox' in the Venetian dialect) is the historic seat of the University of Padua, founded in 1222. A full-length portrait of Thomas Linacre stands in its prestigious Sala dei Quaranta (Hall of the Forty), so called because of the portraits of forty great foreign scholars of the University, painted by Giacomo dal Forno in 1942. Thomas Linacre came to Italy in 1485, following an embassy by Henry VII to the Vatican. Linacre visited Bologna, Florence, Rome, Venice, Vicenza and Padua, where he took his degree in medicine in 1496 with great distinction. During his stay in Italy he met illustrious humanists and physicians, including Poliziano, Hermolaus Barbarus and Aldus Manutius Romanus, and Nicolaus Leonicenus who further stimulated him to the translation of classic works by Hippocrates and Galen. In 1518 Linacre played a pivotal role in the foundation of the Royal College of Physicians in London which, as first President, he organized on the basis of Italian models. With his portrait, the University of Padua celebrates the life and work of an astonishing figure linking the Italian and English medical cultures.

    Thomas K. Jeffers has made many significant contributions to our understanding of the biology of the parasite Eimeria, the cause of coccidiosis in poultry. His work has had direct practical application for the control of this widespread disease. Topics discussed include Jeffers' pioneering work concerned with genetics of the host response to infection, the nature of biological and immunological intraspecific variation, drug resistance and discovery, field surveys of resistance, and his most recognized achievement-the demonstration that the lifecycle of coccidia may be altered by artificial selection. Parasites so modified are attenuated but retain their immunogenicity, a discovery that has led to the development of live vaccines that are inherently non-pathogenic. This article provides a brief biography and describes the contributions that Jeffers has made to our knowledge of coccidiosis.

    Thomas Schwencke (1694-1767) was Professor of Anatomy and Surgery and Lecturer in Obstetrics at the Surgical School in The Hague, the Netherlands. In 1743 he published the very first textbook on haematology. Furthermore, he described his observations on the variolation of smallpox, and published the design of a new obstetric instrument. Schwencke was physician of the city of The Hague and also physician at the court of the princes van Nassau-Weilburg. In 1765 Princess Caroline of Nassau-Weilburg invited the young Wolfgang Amadeus Mozart to perform concerts. During his Dutch tour the young Mozart fell seriously ill, probably from typhoid fever. At the request of the court Mozart was seen for a second opinion and thereafter successfully treated by Schwencke. Mozart could continue his concert tour and Schwencke's reputation as Mozart's physician was established.

    A wealth of different expressions for the frequency of the Thomas precession (TP) can be found in the literature, with the consequence that this issue has been discussed over a long period of time. It is shown that the correct result was obtained in the works of several authors, which were published more than forty years ago but remained unnoticed against the background of numerous erroneous works. Several TP-related physical paradoxes formulated primarily to disprove the special relativity theory are shown to be fallacious. Different techniques for deriving the correct expression are considered and the reasons for the emergence of the main incorrect expressions for the TP frequency are analyzed.

    A selective photon scheme is proposed to realize an N-qubit Greenberger-Horne-Zeilinger (GHZ) state with distant atoms trapped in spatially separated bimodal cavities coupled by optical fibres. The influence of deviations of some experimental parameters on our scheme is studied exactly and we prove that a highly reliable GHZ state is achievable. Moreover, we analyse the independence of fidelity on decoherence processes, such as atomic spontaneous emission, cavity decay and fibre losses. The results show that atomic spontaneous emission and fibre losses can be ignored in some special cases. With regards to the cavity decay, it indicates that a GHZ state with high fidelity may be realized in the current experiment.

    We present an efficient scheme to quickly generate three-qubit Greenberger-Horne-Zeilinger (GHZ) states by using three superconducting qubits (SQs) separated by two coplanar waveguide resonators (CPWRs) capacitively. The scheme is based on quantum Zeno dynamics and the approach of transitionless quantum driving to construct shortcuts to adiabatic passage. In order to highlight the advantages, we compare the present scheme with the traditional one with adiabatic passage. The comparison result shows the shortcut scheme is closely related to the adiabatic scheme but is better than it. Moreover, we discuss the influence of various decoherences with numerical simulation. The result proves that the present scheme is less sensitive to the energy relaxation, the decay of CPWRs and the deviations of the experimental parameters the same as the adiabatic passage. However, the shortcut scheme is effective and robust against the dephasing of SQs in comparison with the adiabatic scheme.

    State conversion between the Greenberger–Horne–Zeilinger (GHZ) state and the W state is a challenging open problem because these states cannot be converted to each other by just local operations and classical communication. Here we propose a cavity quantum electrodynamics method based on interference of polarized photons emitted by the atoms trapped in spatially separated optical cavities that can convert a three-atom W state to a GHZ state. We calculate the success probability and fidelity of the converted GHZ state when the cavity decay, spontaneous atomic decay and photon leakage of the cavities are taken into account for a practical system, which shows that the proposed scheme is feasible and within the reach of current experimental technology.

    As stated by S. Ghose et al. [Phys. Rev. Lett. 102, 250404 (2009)], there are certain relationships between tripartite entanglement and tripartite nonlocality for three-qubit Greenberger-Horne-Zeilinger (GHZ) class states. In the present work, we have experimentally demonstrated the theoretical results of Ghose et al. by using both three-photon generalized GHZ (GGHZ) states and maximal slice (MS) states with a count of {approx}10/s. From the data, we have verified the agreement of the experimental violation of the Svetlichny inequality with the one predicted by quantum mechanics given the reconstructed density matrix. For the MS states, it is demonstrated that the amount of violation increases linearly following the increase of the degree of tripartite entanglement. In contrast, for GGHZ states, there is a minimal value of the violation when the degree of tripartite entanglement is 1/3. Both of the results are consist with the theoretical prediction.

    Quantum squeezing and entanglement of spins can be used to improve the sensitivity in quantum metrology. Here we propose a scheme to create collective coupling of an ensemble of spins to a mechanical vibrational mode actuated by an external magnetic field. We find an evolution time where the mechanical motion decouples from the spins, and the accumulated geometric phase yields a squeezing of 5.9 dB for 20 spins. We also show the creation of a Greenberger-Horne-Zeilinger spin state for 20 spins with a fidelity of ˜0.62 at cryogenic temperature. The numerical simulations show that the geometric-phase-based scheme is mostly immune to thermal mechanical noise.

    2017-10-01

    Channels composed by Einstein-Podolsky-Rosen (EPR) pairs are capable of teleporting arbitrary multipartite states. The question arises whether EPR channels are also optimal against imperfections. In particular, the teleportation of Greenberger-Horne-Zeilinger states (GHZ) requires three EPR states as the channel and full measurements in the Bell basis. We show that, by using two GHZ states as the channel, it is possible to transport any unknown three-qubit state of the form c_0|000\\rangle +c_1|111\\rangle . The teleportation is made through measurements in the GHZ basis, and, to obtain deterministic results, in most of the investigated scenarios, four out of the eight elements of the basis need to be unambiguously distinguished. Most importantly, we show that when both systematic errors and noise are considered, the fidelity of the teleportation protocol is higher when a GHZ channel is used in comparison with that of a channel composed by EPR pairs.

    2017-12-01

    Combining the advantages of the dressed states and superconducting quantum interference device (SQUID) qubits, we propose an efficient scheme to generate Greenberger-Horne-Zeilinger (GHZ) states for three SQUID qubits. Firstly, we elaborate how to generate GHZ states of three SQUID qubits by choosing a set of dressed states suitably. Then, we compare the scheme by using dressed states with that via the adiabatic passage. Lastly, the influence of various decoherence factors, such as cavity decay, spontaneous emission and dephasing, is analyzed numerically. All of the results show that the GHZ state can be obtained fast and with high fidelity and that the present scheme is robust against the cavity decay and spontaneous emission. In addition, our scheme is more stable against the dephasing than the adiabatic scheme.

    Vaidman described how a team of three players, each of them isolated in a remote booth, could use a three-qubit Greenberger-Horne-Zeilinger state to always win a game which would be impossible to always win without quantum resources. However, Vaidman's method requires all three players to share a common reference frame; it does not work if the adversary is allowed to disorientate one player. Here we show how to always win the game, even if the players do not share any reference frame. The introduced method uses a 12-qubit state which is invariant under any transformation R a xR b xR c (where R a =U a xU a xU a xU a , where U j is a unitary operation on a single qubit) and requires only single-qubit measurements. A number of further applications of this 12-qubit state are described

    2017-03-01

    Entanglement, a unique quantum resource with no classical counterpart, remains at the heart of quantum information. The Greenberger-Horne-Zeilinger (GHZ) and W states are two inequivalent classes of multipartite entangled states which cannot be transformed into each other by means of local operations and classic communication. In this paper, we present the methods to prepare the GHZ and W states via global controls on a long-range Ising spin model. For the GHZ state, general solutions are analytically obtained for an arbitrary-size spin system, while for the W state, we find a standard way to prepare the W state that is analytically illustrated in three- and four-spin systems and numerically demonstrated for larger-size systems. The number of parameters required in the numerical search increases only linearly with the size of the system.

    Chen Lixiang; She Weilong

    2011-01-01

    We propose a scheme to generate hybrid Greenberger-Horne-Zeilinger (GHZ) entanglement where multiple photons are entangled in different degrees of freedom of spin, orbital angular momentum (OAM), and path (linear momentum). The generation involves mapping the preliminary OAM entanglement of photon pairs onto their spin-orbit and spin-path degrees of freedom, respectively. Based on the hybrid GHZ entanglement, we demonstrate an open-destination teleportation with multiples degrees of freedom, via which a spin state of a single photon is teleported onto a superposition of multiple photons with the postselection technique and the original information could be read out at any photon in individual spin, OAM, or the linear-momentum state. Our scheme holds promise for asymmetric optical quantum network.

    2015-01-01

    We present a scheme for implementing locally a nonlocal N-target controlled–controlled gate with unit probability of success by harnessing two (N+1)-qubit Greenberger–Horne–Zeilinger (GHZ) states as quantum channel and N qutrits as catalyser. The quantum network that implements this nonlocal (N+2)-body gate is built entirely of local single-body and two-body gates, and has only (3N+2) two-body gates. This result suggests that both the computational depth of quantum network and the quantum resources required to perform this nonlocal gate might be significantly reduced. This scheme can be generalized straightforwardly to implement a nonlocal N-target and M-control qubits gate. (paper)

    A quantum steganography protocol with a large payload is proposed based on the dense coding and the entanglement swapping of the Greenberger—Horne—Zeilinger (GHZ) states. Its super quantum channel is formed by building up a hidden channel within the original quantum secure direct communication (QSDC) scheme. Based on the original QSDC, secret messages are transmitted by integrating the dense coding and the entanglement swapping of the GHZ states. The capacity of the super quantum channel achieves six bits per round covert communication, much higher than the previous quantum steganography protocols. Its imperceptibility is good, since the information and the secret messages can be regarded to be random or pseudo-random. Moreover, its security is proved to be reliable. (general)

    To enhance the efficiency of eavesdropping detection in the quantum secure direct communication protocol, an improved quantum secure direct communication protocol based on a four-particle Green-Horne-Zeilinger (GHZ) state is presented. In the protocol, the four-particle GHZ state is used to detect eavesdroppers, and quantum dense coding is used to encode the message. In the security analysis, the method of entropy theory is introduced, and two detection strategies are compared quantitatively by using the constraint between the information that the eavesdroppers can obtain and the interference that has been introduced. If the eavesdropper wants to obtain all the information, the detection rate of the quantum secure direct communication using an Einstein-Podolsky-Rosen (EPR) pair block will be 50% and the detection rate of the presented protocol will be 87%. At last, the security of the proposed protocol is discussed. The analysis results indicate that the protocol proposed is more secure than the others. (orig.)

  7. Thomas Piketty’s capitalism revisited

    2015-01-01

    Full Text Available Thomas Piketty’s international best selling Capital in the Twenty-First Century lays out his theory of a long-run rise in income inequality under capitalism. It is written as a manifesto urging reintegration of social sciences. A number of reviewers judged it on ideological grounds, labeling it either as a revolution in economic thinking, or dismissing it offhandedly. Piketty’s theory of rising inequality is based on the two Fundamental Laws of Capitalism, developed after the Solow growth model. However, this model is inconsistent with Piketty’s own characterization of modern capitalism. Moreover, his sole justification for the constant discrepancy between rate of return and rate of income growth (r > g is based on the high elasticity of substitution between capital and labor. However, that is just one factor that can have an influence on factor income shares. By failing to offer a consistent theory of rising inequality, his piece can hardly be considered as a useful founding stone for a new social science.

  8. The nuclear Thomas-Fermi model

    Myers, W.D.; Swiatecki, W.J.

    1994-08-01

    The statistical Thomas-Fermi model is applied to a comprehensive survey of macroscopic nuclear properties. The model uses a Seyler-Blanchard effective nucleon-nucleon interaction, generalized by the addition of one momentum-dependent and one density-dependent term. The adjustable parameters of the interaction were fitted to shell-corrected masses of 1654 nuclei, to the diffuseness of the nuclear surface and to the measured depths of the optical model potential. With these parameters nuclear sizes are well reproduced, and only relatively minor deviations between measured and calculated fission barriers of 36 nuclei are found. The model determines the principal bulk and surface properties of nuclear matter and provides estimates for the more subtle, Droplet Model, properties. The predicted energy vs density relation for neutron matter is in striking correspondence with the 1981 theoretical estimate of Friedman and Pandharipande. Other extreme situations to which the model is applied are a study of Sn isotopes from 82 Sn to 170 Sn, and the rupture into a bubble configuration of a nucleus (constrained to spherical symmetry) which takes place when Z 2 /A exceeds about 100

    The FT 648 type portable absolute radon meter has been developed and the designing principle of this instrument is introduced. The absolute radon meter differs from relative radon meter. By using structure parameters, operating parameters and readout of this instrument, the radon content of measured gas is obtained directly without calibration in advance. Normally, the calibration is done by a standard radioactive gaseous source of which the radon concentration is known. The systematic error is removed by adding filter-efficiency Σ, α self-absorption correction β, energy spectrum correction S, geometric factor Ω of probe and gravity dropping correction factor G to the Thomas formula for radon measurement of two-filter method. The atmosphere radon content, which is given in hour-average, in Beijing area was measured by FT 648 type absolute radon meter. The measurement lasted continuously for several days and nights and a 'saddle shape' of radon content-time curve was observed. The day's average radon content was 8.5 Bq·m -3

    Thomas J. Ahrens, a leader in the study of high-pressure shock wave and planetary impact phenomena, died at his home in Pasadena, Calif., on 24 November 2010 at the age of 74. He was the California Institute of Technology's Fletcher Jones Professor of Geophysics, emeritus since 2005 but professionally active to the end. He had been president of AGU's Tectonophysics section, editor of Journal of Geophysical Research, founding member of both the Mineral and Rock Physics and Study of the Earth's Deep Interior focus groups, and editor—more like key driving force—for AGU's Handbook of Physical Constants. Tom was a pioneer in experimental and numerical studies of the effects of projectiles hitting a target at velocities exceeding the speed of sound (hypervelocity impact), arguably the most important geophysical process in the formation, growth, and, in many cases, surface evolution of planets. As a professor at Caltech, he established the foremost university laboratory for shock wave experiments, where students and research associates from around the world pursued basic research in geophysics, planetary science, and other disciplines. Previously, high-pressure shock experiments were conducted primarily in national laboratories, where they were initially associated with the development of nuclear weapons.

    The aim of this study was to assess the contributions of Thomas Waters's work in the field of health care ergonomics and beyond. Waters's research of safe patient handling with a focus on reducing musculoskeletal disorders (MSDs) in health care workers contributed to current studies and prevention strategies. He worked with several groups to share his research and assist in developing safe patient handling guidelines and curriculum for nursing students and health care workers. The citations of articles that were published by Waters in health care ergonomics were evaluated for quality and themes of conclusions. Quality was assessed using the Mixed Methods Appraisal Tool and centrality to original research rating. Themes were documented by the type of population the citing articles were investigating. In total, 266 articles that referenced the top seven cited articles were evaluated. More than 95% of them were rated either medium or high quality. The important themes of these citing articles were as follows: (a) Safe patient handling is effective in reducing MSDs in health care workers. (b) Shift work has negative impact on nurses. (c) There is no safe way to manually lift a patient. (d) Nurse curriculums should contain safe patient handling. The research of Waters has contributed significantly to the health care ergonomics and beyond. His work, in combination with other pioneers in the field, has generated multiple initiatives, such as a standard safe patient-handling curriculum and safe patient-handling programs. © 2016, Human Factors and Ergonomics Society.

Guralnik and C. Hagen in the autumn of that year, following the papers by R. Brout and F. Englert and by P. Higgs. When this new understanding was incorporated into a model proposed by S.

    2014-04-01

    Full Text Available The tradition of spoken-word recording began with Thomas Edison’s invention of the phonograph. Hence, this article makes the case that 1878 is a more important year to the history of literature than has yet been recognized for its experiments with verse and sound-recording technology. Although the tinfoil phonograph’s first decade has been well documented by media historians, literary critics have singled out 1888 as the noteworthy year since that is when Edison’s improved phonograph made it possible to record prominent figures including Alfred Tennyson and Robert Browning. Taking Edison’s original tinfoil phonograph as an alternative starting point reveals how the 1878 phonograph demonstrations, despite technological limitations, undertook acoustic experiments that enabled audiences to discern new forms of meaning, pleasure, and pathos in even the most well-known material. The recordings considered here include ‘Mary Had a Little Lamb’ as well as scripts by Tennyson, Caroline Norton, Edgar Allan Poe, Shakespeare, and others. Such recitals illustrate the extent to which Edison’s talking machine influenced the reception of texts while at the same time giving rise to performances unheard of in previous cultures.

  17. Electron-electron Thomas peak in fast transfer ionization

    Tolmanov, S. G.; McGuire, J. H.

    2000-01-01

    ''Thomas process'' is a name used for a family of singular two-step processes that can lead to electron transfer. The Thomas process of the ''second kind,'' occurring in reactions with both transfer and ionization, utilizes the e-e scattering in the second step, so this Thomas process requires the dynamics of the electron-electron interaction. We calculate numerically the second order element of an S matrix and corresponding cross sections for the transfer ionization process. We find that the position and shape of the Thomas peak depend on both electron-electron and the electron-nucleus interaction. Also the direct and exchange amplitudes are equal at the peak position. We test the peaking approximation used for transfer ionization. Our results can be compared to experimental results for p + +He→H+He 2+ +e - . (c) 2000 The American Physical Society

    We investigate the relativistic finite-temperature Thomas-Fermi model, which has been proposed recently in an astrophysical context. Assuming a constant distribution of protons inside the nucleus of finite size avoids severe divergence of the electron density with respect to a point-like nucleus. A formula for the nuclear radius is chosen to treat any element. The relativistic finite-temperature Thomas-Fermi model matches the two asymptotic regimes, i.e., the non-relativistic and the ultra-relativistic finite-temperature Thomas-Fermi models. The equation of state is considered in detail. For each version of the finite-temperature Thomas-Fermi model, the pressure, the kinetic energy, and the entropy are calculated. The internal energy and free energy are also considered. The thermodynamic consistency of the three models is considered by working from the free energy. The virial question is also studied in the three cases as well as the relationship with the density functional theory. The relativistic finite-temperature Thomas-Fermi model is far more involved than the non-relativistic and ultra-relativistic finite-temperature Thomas-Fermi models that are very close to each other from a mathematical point of view.

    Full Text Available Nella prolusione al suo corso al Collège de France, pronunciata il 6 aprile 2006, Thomas Pavel si interroga sugli aspetti emotivi ed etici dell'attività della lettura, sull'“abbandonarsi” di chi legge all'opera letteraria. Come avviene la trasfigurazione del quotidiano nel mondo finzionale? Come si svolge il processo di identificazione dell'io nell'opera? Lo studioso rintraccia il fondamento di tale processo nella non coincidenza di principio tra io e vita, quindi nella facoltà del lettore di accogliere e riconoscere il senso dell'opera. Un senso che tuttavia non si palesa una volta per tutte nella sua interezza e trasparenza, ma che diviene oggetto di continuo dialogo fra i lettori, un senso quindi affidato alle loro cure.During the opening lecture of his course at Collège de France, held on April 6th 2006, Thomas Pavel talks about the emotional and ethical aspects of reading and about «completely surrending» to literature.

The scholar traces the origin of this process to the radically different principles governing ego and life. Because of this, the reader is able to grasp and understand the real meaning of the book. This, however, is never completely revealed in a clear way. Instead, it becomes the object of a never-ending dialogue among the readers: it is therefore their care the meaning is entrusted to.Во вступлении к своему курсу лекций во Французском Колледже, произнесенном 6-го апреля 2006-го года, Томас Павел размышляет о эмоциональных и этических сторонах чтения, о том, как читатель «отдается» литературному произведению.

    The astronomy community lost a good friend when Tom Metcalf was killed in a skiing accident on Saturday, 7 July 2007, in the mountains near Boulder, Colorado. Tom was widely known for prolific work on solar magnetic fields, hard-X-ray imaging of solar flares, and spectral line diagnostics. He was often characterized as "one of the nicest guys in science." Born October 5, 1961 in Cheverly, Maryland, to Fred and Marilyn, Thomas R. Metcalf joined his sister, Karen, two years his elder, in a close family that loved sailing, inquisitiveness, and the natural world. Sibling rivalry (usually a Tonka truck intruding on Barbie's sub-table "castle") melted when Tom and Karen collaborated on elaborately engineered room-sized blanket-forts. Tom confidently signed up at age of three to crew for his family's sailboat; when the family moved to California in 1966, as Tom's father took a Professor of Mathematics position at the University of California Riverside, Tom's love for sailing was well-established. Week-long cruises or short trips in the harbor were all fun; when school friends came aboard, it was even better--if "only slightly too crowded" from the adults' points of view. Tom's introduction to astronomy began one cold, very clear, December night in the early 1970s, on a family camping trip to Death Valley. The "Sidewalk Astronomers of San Francisco" had lined the sidewalk near the visitors' center with all sorts of telescopes for public viewing. Soon after, Tom and his boyhood friend Jim O'Linger were building their own scopes, attending "Amateur Telescope Makers" conferences, and Tom was setting up his scope on a sidewalk for public viewing. In 1986, Tom set up his telescope on the bluffs above Dana Point Harbor, and gave numerous strangers a stunning view of Halley's Comet. His interest in physics and mathematics became evident during Tom's last years in high school (Poly High in Riverside), and as a senior he qualified to take freshman Physics at the University of

    Over the years, I've daydreamed about stealing a Vermeer, a Picasso, or Rembrandt. It tickles me, as much as watching the reboot of The Thomas Crown Affair. Why is it, do you suppose, so much fun to think about stealing a world renowned piece off the wall of a major metropolitan museum? Is it the romantic thoughts of getting away with it, walking past infrared detectors, and pressure sensors ala Indiana Jones with the sack of sand to remove the idol without triggering the security system? Is it the idea of snatching items with such fantastic prices, where the romance of possessing an item of such value is less intoxicating than selling it to a private collector for it to never be seen again? I suspect others share my daydreams as they watch theater or hear of a brazen daylight heist at museums around the world, or from private collections. Though when reality sets in, the mind of the security professional kicks in. How could one do it, why would one do it, what should you do once it's done? The main issue a thief confronts when acquiring unique goods is how to process or fence them. They become very difficult to sell because they are one-of-a-kind, easy to identify, and could lead to the people involved with the theft. The whole issue of museum security takes up an ironic twist when one considers the secretive British street artist 'Banksy'. Banksy has made a name for himself by brazenly putting up interesting pieces of art in broad daylight (though many critics don't consider his work to be art) on building walls, rooftops, or even museums. I bring him up for a interesting take on what may become a trend in museum security. In March of 2005, Banksy snuck a piece of his called 'Vandalized Oil Painting' into the Brooklyn Museum's Great Historical Painting Wing, plus 3 other pieces into major museums in New York. Within several days, 2 paintings had been torn down, but 2 stayed up much longer. In his home country of the UK, a

    Physiological changes during pregnancy affect routine tests for iron deficiency. The reticulocyte haemoglobin equivalent (RET-He) and serum-soluble transferrin receptor (sTfR) assay are newer diagnostic parameters for the detection of iron deficiency, combined in the Thomas diagnostic plot. We used this plot to determine the iron status of pregnant women presenting for their first visit to an antenatal clinic in Bloemfontein, South Africa. Routine laboratory tests (serum ferritin, full blood count and C-reactive protein) and RET-He and sTfR were performed. The iron status was determined using the Thomas plot. For this study, 103 pregnant women were recruited. According to the Thomas plot, 72.8% of the participants had normal iron stores and erythropoiesis. Iron-deficient erythropoiesis was detected in 12.6%. A third of participants were anaemic. Serum ferritin showed excellent sensitivity but poor specificity for detecting depleted iron stores. HIV status had no influence on the iron status of the participants. Our findings reiterate that causes other than iron deficiency should be considered in anaemic individuals. When compared with the Thomas plot, a low serum ferritin is a sensitive but nonspecific indicator of iron deficiency. The Thomas plot may provide useful information to identify pregnant individuals in whom haematologic parameters indicate limited iron availability for erythropoiesis. © 2015 John Wiley & Sons Ltd.

    Vivien Thomas (1910-1985) was an African-American scientist, pioneer, and renowned educator. Thomas's contributions to cardiovascular surgery were unequivocal, and yet it was only after his death that he gained more widespread recognition. Thomas's more notable work involves aiding in the discovery of the cause of traumatic shock, designing and guiding the first operation to treat Tetralogy of Fallot, carrying out the first atrial septectomy, and helping develop the electrical defibrillator. Thomas struggled amidst the adversities of racism and the Great Depression (1929-1941), armed merely with a high school degree. Nevertheless, his genius and determination eventually led him to receive an honorary doctorate from John Hopkins University. His story inspired the creation of the award winning PBS documentary in 2003 Partners of the Heart and also the 2004 Emmy Award-winning HBO film Something the Lord Made. This article will aim to provide an overview to the more notable events in Thomas's amazing tale, with a particular focus on his work on the Tetralogy of Fallot.

    Full Text Available Josef Strzygowski (1862-1941 is remembered primarily as attracting a Pan-Germanic audience when his early career and most prominent publications actually promoted materials from outside of the classical tradition then being overlooked or ignored. From the list of his students and their topics of study, it is clear that his audience was probably more diverse than most. The list of his publications and his students and their topics of study should give some idea of this. Some of his emphasis was actually typical of his time and place and reflected the growth in popular tourism and travel. His expeditions by camel to photograph remote architecture and sculpture in near eastern areas prone to earthquakes and plagued by armed conflicts have preserved many important examples of art that have since been damaged or lost.

    We propose and prove protocols of combined and controlled remote implementations of partially unknown quantum operations belonging to the restricted sets [A. M. Wang, Phys. Rev. A 74, 032317 (2006)] using Greenberger-Horne-Zeilinger (GHZ) states. We present the protocols in detail in the cases of one qubit, with two senders and with one controller, respectively. Then we study the variations of protocols with many senders, or with many controllers, or with both many senders and controllers using a multipartite GHZ state. Furthermore, we extend these protocols to the cases of multiqubits. Because our protocols have to request that the senders work together and transfer the information in turn or receive the repertoire of extra supercontrollers, or/and the controller(s) open the quantum channel and distribute the passwords in different ways, they definitely have the strong security in remote quantum information processing and communications. Moreover, the combined protocol with many senders is helpful to arrive at the power of remote implementations of quantum operations to the utmost extent in theory, since the different senders may have different operational resources and different operational rights in practice, and the controlled protocol with many controllers is able to enhance security and increase applications of remote implementations of quantum operations in engineering, since it has some common features in a controlled process

It is not surprising therefore to see that this new publication will be dedicated to the subject of international law, both public and private. Its laudable aim is to promote legal discourse around the world, and to promote a wider international understanding of contemporary legal issues for the common benefit. As an open access, bilingual journal, addressing topics concerning any jurisdiction, I hope it will reach a wide audience, and fulfil its aim of promoting understanding between different cultures. I am sure that the journal will not only benefit Qatar’s legal community by advancing academic and practice-based legal discussion.

    Thomas M. Donahue, one of the nation's leading space and planetary scientists and a pioneer of space exploration, died Saturday October 16, 2004, from complications following heart surgery. The Edward H. White II Distinguished University Professor of Planetary Science at the University of Michigan, Tom shaped space exploration through his scientific achievements and policy positions. His work started with the first use of sounding rockets following World War II and continued for almost 60 years. Tom was born in Healdton, Oklahoma on May 23, 1921 to Robert Emmet and Mary (Lyndon) Donahue. His father was a plumber in the oil fields when Tom was born (Healdton OK was an oil town) and worked as a plumber in Kansas City for a time. Tom grew up in Kansas City, graduating in 1942 from Rockhurst College in that city with degrees in classics and physics. His graduate work in physics at Johns Hopkins University was interrupted by service in the Army Signal Corps. He obtained his PhD degree in atomic physics from Hopkins in the fall of 1947. After three years as a post-doctoral research associate and assistant professor at Hopkins, Tom joined the University of Pittsburgh Physics Department in 1951. At Pittsburgh he organized an atomic physics and atmospheric science program that led to experimental and theoretical studies of the upper atmosphere of the Earth and other solar system planets with instruments flown on sounding rockets and spacecraft. He became Professor of Physics in 1959 and eventually Director of the Laboratory for Atmospheric and Space Sciences and the Space Research Coordination Center at the University. In 1960 he spent a sabbatical year on a Guggenheim Fellowship at the Service d'Aeronomie in Paris, which began collaborations with French colleagues that flourished for more than 40 years. In 1974 he became the Chairman of the Atmospheric and Oceanic Science Department, University of Michigan, a position he held until 1981. In 1986, he was named the Henry

    Two corrections to the Thomas-Fermi theory of atoms are studied. First the correction for exchange, that is the effect of the Pauli principle in the interaction energy, is considered. The defining variational problem is non-convex and standard technique to prove existence of a minimizing solution do not apply. Existence and uniqueness of solutions are established by convexifying or relaxing the energy functional. Properties of the minimizing solution are studied. A second correction due to von Weizsaecker is also discussed. Finally the dual principle to the Thomas-Fermi variational problem is studied (only in the neutral case). A dual principle is suggested for the ionic case. Also, a review of recent rigorous results concerning Thomas-Fermi theory is presented

  15. Obituary: Thomas Julian Ahrens (1936-2010)

    Science.gov (United States)

    Jeanloz, Raymond; Asimow, Paul

    2011-12-01

    Thomas J. Ahrens, a leader in the use of shock waves to study planetary interiors and impact phenomena, died at his home in Pasadena, California on November 24, 2010, at the age of 74. He was the California Institute of Technology's Fletcher Jones Professor of Geophysics, formally emeritus since 2005 but professionally active to the end. Tom was a pioneer in experimental and numerical studies of the effects of hypervelocity impact, arguably the most important geophysical process in the formation, growth and - in many cases - surface evolution of planets. As a professor at Caltech, he established the foremost university laboratory for shock wave experiments, where students and research associates from around the world pursued basic research in geophysics, planetary science and other disciplines. Previously, high-pressure shock experiments were primarily conducted in national laboratories, where they were initially associated with development of nuclear weapons. The shock wave laboratory at Caltech was noted for key measurements addressing major questions in planetary geophysics. Equation-of-state studies on silicate melts showed that magma deep in Earth's mantle could be denser than the coexisting crystals, implying downward transport of melts (and associated heat) rather than the upward eruption of lavas observed in volcanic regions at Earth's surface. Shock-melting experiments on iron at pressures of Earth's core provide a crucial constraint on the temperature at the center of our planet. And studies of hydrous, carbonate and sulphate minerals under shock compression document how climate-altering molecules can be released by major impacts, such as the K/T event associated with the most recent mass extinction of biota in Earth history. In addition, Tom was a leader in numerical simulation of cratering, bringing the most recent laboratory measurements into the modeling of planetary impacts. Tom's training was in geophysics and applied experimental physics, as

  16. Thomas Henry Huxley et la Bible Thomas Henry Huxley and the Bible

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Thomas Henry Huxley devoted several essays to the study of the Bible. This interest can only be accounted for if his ideas on history, religion as well as epistemology are examined. According to him, a struggle between free thought and supernaturalism was culminating during the Victorian era, hence the need for a “New Reformation” which was heir to the ideals of freedom defended by the humanists of the Renaissance. This movement opposed the principles of the supporters of what he called “ecclesiasticism”. The advocates of the “New Reformation” could rely on the progress of modern science, and agnosticism, which Huxley identified with scientific method, became its epistemological foundation. As a result, Huxley thought that the authority of physical science was in conflict with the infallibility of the Scriptures and with the theological arguments which rested on it, and this notably led him to the conclusion that the biblical narrative of the Flood was unhistorical. The naturalisation of the Scriptures seems then logically to follow his philosophical views based on the limits of human knowledge.It appears that it was the question of authority which underlay Huxley’s interest in the Bible. He thought that the authority of the Scriptures must be replaced by that of science.

  17. Fast generation of three-qubit Greenberger-Horne-Zeilinger state based on the Lewis-Riesenfeld invariants in coupled cavities.

    Science.gov (United States)

    Huang, Xiao-Bin; Chen, Ye-Hong; Wang, Zhe

    2016-05-24

    In this paper, we propose an efficient scheme to fast generate three-qubit Greenberger-Horne-Zeilinger (GHZ) state by constructing shortcuts to adiabatic passage (STAP) based on the "Lewis-Riesenfeld (LR) invariants" in spatially separated cavities connected by optical fibers. Numerical simulations illustrate that the scheme is not only fast, but robust against the decoherence caused by atomic spontaneous emission, cavity losses and the fiber photon leakages. This might be useful to realize fast and noise-resistant quantum information processing for multi-qubit systems.

    Based on superconducting flux qubits coupled to a superconducting resonator. We propose a scheme for implementing multi-qubit controlled-NOT (C-NOT) gates and Greenberger-Horne-Zeilinger (GHZ) state with one flux qubit simultaneously controlling on n qubits. It is shown that the resonator mode is initially in the vacuum state, a high fidelity for operation procedure can be obtained. In addition, the gate operation time is independent of the number of the qubits, and can be controlled by adjusting detuning and coupling strengths. We also analyze the experimental feasibility that the conditions of the large detuning can be achieved by adjusting frequencies of the resonator and pulses.

    A scheme is proposed for generating Greenberger-Horne-Zeilinger (GHZ) entangled states of multiple superconducting quantum-interference device (SQUID) qubits by the use of a microwave cavity. The scheme operates essentially by creating a single photon through an auxiliary SQUID built in the cavity and performing a joint multiqubit phase shift with assistance of the cavity photon. It is shown that entanglement can be generated using this method, deterministic and independent of the number of SQUID qubits. In addition, we show that the present method can be applied to preparing many atoms in a GHZ entangled state, with tolerance to energy relaxation during the operation

    We show that the partition functions which enumerate Donaldson-Thomas invariants of local toric Calabi-Yau threefolds without compact divisors can be expressed in terms of specializations of the Schur measure. We also discuss the relevance of the Hall-Littlewood and Jack measures in the context of BPS state counting and study the partition functions at arbitrary points of the Kaehler moduli space. This rewriting in terms of symmetric functions leads to a unitary one-matrix model representation for Donaldson-Thomas theory. We describe explicitly how this result is related to the unitary matrix model description of Chern-Simons gauge theory. This representation is used to show that the generating functions for Donaldson-Thomas invariants are related to tau-functions of the integrable Toda and Toeplitz lattice hierarchies. The matrix model also leads to an interpretation of Donaldson-Thomas theory in terms of non-intersecting paths in the lock-step model of vicious walkers. We further show that these generating functions can be interpreted as normalization constants of a corner growth/last-passage stochastic model.

  6. Obituary: Thomas Gold, 1920-2004

    Science.gov (United States)

    Dermott, Stanley F.

    2004-12-01

    Thomas "Tommy" Gold died of heart disease at Cayuga Medical Center, Ithaca NY on 22 June 2004 at the age of 84. He will be remembered as one of the most interesting, dynamic and influential scientists of his generation. Tommy's paradigm-changing ideas in astronomy and planetary science, while original and bold, were also highly controversial. With his radical work on the origin of natural gas and petroleum, the controversy is likely to continue. Tommy was born in Vienna, Austria on 22 May 1920, moving with his family to Berlin at age 10 and then, after the rise of Hitler in 1933, to England. His parents were Josephine (nee Martin) and Maximillian Gold, a successful steel magnate. Tommy was educated at Zuoz College in Switzerland where he became an expert skier and developed an athletic prowess that he maintained throughout his life, winning a NASTAR gold medal for skiing at the age of 65. He studied Mechanical Sciences at Trinity College, Cambridge, but much to his disgust his education was interrupted because of internment by the British as a suspected enemy alien. That unfortunate period (I remember him saying to me "Can you believe the stupidity, interring people like me who had fled from Nazi Germany?") had one good outcome: on his first night in camp he met Hermann Bondi who had an important influence on his early development as a scientist. They were both born in Vienna, their parents knew each other, and they were fellow students at Trinity, but this was their first meeting. On release, he went immediately into top-secret radar research for the British Admiralty, working as a team with Bondi and Fred Hoyle in a farm cottage in Dunsfold, Surrey. Tommy's first published research, which was a Nature paper with R.J. Pumphrey in 1947, was not in astronomy but physiology. He applied his engineer's understanding of positive feedback to develop and test a resonance model for how the human ear determines pitch. His conclusion that pitch discrimination occurs

    We compare the Bakamjian-Thomas (BT) formulation of relativistic few-body systems with light-front field theories that maintain closer contact with Feynman diagrams. We find that Feynman diagrams distinguish Melosh rotations and other kinematical quantities belonging to various composite subsystem frames that correspond to different loop integrals. The BT formalism knows only the rest frame of the whole composite system, where everything is evaluated. (author)

    Within the Thomas-Fermi model including the exchange interaction and contributions of strongly bound electrons, analytical expressions are obtained for all momentum expectation values and for some of the expectation values of powers of the electron density for an atom with an arbitrary degree of ionization. It is shown that a correct treatment of strongly bound electrons gives a quantitative estimate of and within 3 - 1 expansion coefficients for and are given as an explicit function of the electron number

  2. Safety Performance Improvement for Nuclear Power Plants Utilizing THOMAS

    THOMAS (Thermal Hydraulics Online Monitoring Advisory System) is equipped with a couple of salient features compared with existing monitoring systems. The first has to do with the three-dimensional (3D) visualization technique to support the nuclear power plant (NPP) operators and personnel using the virtual reality (VR) technology. VR depicts an environment simulated by a computer. Most of the VR environments primarily include visual experiences, displayed either on a monitor or though special stereoscopic goggles. Users can often interactively manipulate a VR environment, either through standard input devices like a keyboard, or through specially designed devices like a cybergloves. Additional devices were not applied the in THOMAS. The visualized model file is brought to the VR space from the computer-aided design (CAD) tool. In the VR space, using mapping, the component color is changed with linked value of the safety variables. Operators thus can easily recognize the plant condition. This is related with the human factor engineering. The second is the function of decision making using the influence diagram logic. The influence diagram logic is based on the total probability and Bayesian theory. The accident modeling is rooted in the emergency operating procedure (EOP). The final goal of this system is, in the accident situation, to present a success path to the operator for the recovery of the NPP system. At the current developing level, the database signals THOMAS. In other words, a spectrum of system analysis codes provides the safety parameter values to the database, which are subsequently supplied to THOMAS through the network

  5. Preparation of n-qubit Greenberger-Horne-Zeilinger entangled states in cavity QED: An approach with tolerance to nonidentical qubit-cavity coupling constants

    International Nuclear Information System (INIS)

    2011-01-01

    We propose a way for generating n-qubit Greenberger-Horne-Zeilinger (GHZ) entangled states with a three-level qubit system and (n-1) four-level qubit systems in a cavity. This proposal does not require identical qubit-cavity coupling constants and thus is tolerant to qubit-system parameter nonuniformity and nonexact placement of qubits in a cavity. The proposal does not require adjustment of the qubit-system level spacings during the entire operation. Moreover, it is shown that entanglement can be deterministically generated using this method and the operation time is independent of the number of qubits. The present proposal is quite general, which can be applied to physical systems such as various types of superconducting devices coupled to a resonator or atoms trapped in a cavity.

    2018-01-01

    We present a scheme for multiparty-controlled joint remote preparation of an arbitrary m-qudit state by using d-dimensional Greenberger-Horne-Zeilinger (GHZ) states as the quantum channel. An arbitrary m-qudit state can be transmitted from two senders to a remote receiver in a quantum communication network under the controller's control. The senders perform m-qudit measurements according to their information of prepared state, the controllers only need perform single-particle projective measurements. The receiver can prepare the original state on his quantum system by performing corresponding unitary operation according the measurement results of the senders and controllers. It is shown that an arbitrary m-qudit state in general form can be controlled joint remote prepared if and only if the receiver cooperates with all the senders and controllers.

  7. Probabilistic Controlled Teleportation of a Triplet W State with Combined Channel of Non-Maximally Entangled Einstein–Podolsky–Rosen and Greenberger–Horne–Zeilinger States

    International Nuclear Information System (INIS)

    2009-01-01

    A scheme for probabilistic controlled teleportation of a triplet W state using combined non-maximally entangled channel of two Einstein–Podolsky–Rosen (EPR) states and one Greenberger–Horne–Zeilinger (GHZ) state is proposed. In this scheme, an (m + 2)-qubit GHZ state serves not only as the control parameter but also as the quantum channel. The m control qubits are shared by m supervisors. With the aid of local operations and individual measurements, including Bell-state measurement, Von Neumann measurement, and mutual classical communication etc., Bob can faithfully reconstruct the original state by performing relevant unitary transformations. The total probability of successful teleportation is only dependent on channel coefficients of EPR states and GHZ, independent of the number of supervisor m. This protocol can also be extended to probabilistic controlled teleportation of an arbitrary N-qubit state using combined non-maximally entangled channel of N – 1 EPR states and one (m + 2)-qubit GHZ.

  9. Warm ''pasta'' phase in the Thomas-Fermi approximation

    Avancini, Sidney S.; Menezes, Debora P.; Chiacchiera, Silvia; Providencia, Constanca

    2010-01-01

    In the present article, the 'pasta' phase is studied at finite temperatures within a Thomas-Fermi (TF) approach. Relativistic mean-field models, both with constant and density-dependent couplings, are used to describe this frustrated system. We compare the present results with previous ones obtained within a phase-coexistence description and conclude that the TF approximation gives rise to a richer inner ''pasta'' phase structure and the homogeneous matter appears at higher densities. Finally, the transition density calculated within TF is compared with the results for this quantity obtained with other methods.

  10. Shell model test of the Porter-Thomas distribution

    Eigenvectors have been calculated for the A=18, 19, 20, 21, and 26 nuclei in an sd shell basis. The decomposition of these states into their shell model components shows, in agreement with other recent work, that this distribution is not a single Gaussian. We find that the largest amplitudes are distributed approximately in a Gaussian fashion. Thus, many experimental measurements should be consistent with the Porter-Thomas predictions. We argue that the non-Gaussian form of the complete distribution can be simply related to the structure of the Hamiltonian

    We use the continuum shell model approach to explore the resonance width distribution in unstable many-body systems. The single-particle nature of a decay, the few-body character of the interaction Hamiltonian, and the collectivity that emerges in nonstationary systems due to the coupling to the continuum of reaction states are discussed. Correlations between the structures of the parent and daughter nuclear systems in the common Fock space are found to result in deviations of decay width statistics from the Porter-Thomas distribution.

    1983-01-01

    Recent shell model calculations have yielded width amplitude distributions which have apparently not agreed with the Porter-Thomas distribution. This result conflicts with the present experimental evidence. A reanalysis of these calculations suggests that, although correct, they do not imply that the Porter-Thomas distribution will fail to describe the width distributions observed experimentally. The conditions for validity of the Porter-Thomas distribution are discussed

    We construct noncommutative Donaldson-Thomas invariants associated with abelian orbifold singularities by analyzing the instanton contributions to a six-dimensional topological gauge theory. The noncommutative deformation of this gauge theory localizes on noncommutative instantons which can be classified in terms of three-dimensional Young diagrams with a colouring of boxes according to the orbifold group. We construct a moduli space for these gauge field configurations which allows us to compute its virtual numbers via the counting of representations of a quiver with relations. The quiver encodes the instanton dynamics of the noncommutative gauge theory, and is associated to the geometry of the singularity via the generalized McKay correspondence. The index of BPS states which compute the noncommutative Donaldson-Thomas invariants is realized via topological quantum mechanics based on the quiver data. We illustrate these constructions with several explicit examples, involving also higher rank Coulomb branch invariants and geometries with compact divisors, and connect our approach with other ones in the literature.

  6. Some notes on time dependent Thomas Fermi approximation

    International Nuclear Information System (INIS)

    Holzwarth, G.

    1979-01-01

    The successful use of effective density-dependent potentials in static Hartree-Fock calculations for nuclear ground-state properties has led to the question whether it is possible to obtain significant further simplification by approximating also the kinetic energy part of the ground state energy by a functional of the local density alone. The great advantage of such an approach is that its complexity is independent of particle number; the size of the system enters only through parameters, Z and N. The simple 'extended Thomas Fermi' functionals are based on the assumption of a spherically symmetric local Fermi surface throughout the nucleus and they represent the 'liquid drop' part of the static total energy. Given this static formalism which is solved directly for the local density without considering individual particles one might ask for a possible dynamical extension in the same sense as TDHF is a dynamical extension of the static HF approach. The aim of such a Time Dependent Thomas Fermi (TDTF) approximation would be to determine directly the time-dependent local single-particle density from given initial conditions and the single-particle current density without following each particle on its individual orbit

This short story tells about two female character have closerelationship to the same man. The man comes from upper class. The first woman from lower class has a son of his, but they do not live together. Then, the second one is his new young wife. This short story takes rural area, Dorset as the setting of place where the society has intimate relationships and setting of time is in Victorian era. It applied feminism theory that focuses on male and female positions in society. Beauvoir (1949 considered that the male in French and Western societies defines what it means to be human and what it means to be female. The female becomes subordinate to the male. It applies qualitative analysis method. The text is analyzed relating to the female characters‘ position in society. Their positions make them get discrimination which society created. Thomas Hardy‘s short story will be analyzed on discrimination to female characters. The data shows that the two female characters are oppressed on their conditions. Although they do not get physical harassment, the oppression comes from social injustice that women do not get equal benefit and opportunities. Both of them survive to obtain what they need. These characters use their ways as the survivors because of unfair condition.

    Full Text Available Generalmente cuando se aborda el mercantilismo se hace referencia a la acumulación de oro y plata, una balanza de pagos favorable o a la política económica de Jean Colbert. Pero poco se ha hablado del papel y condiciones necesarias del comerciante como agente que hizo posible que los primeros Estados-Nación se convirtieran en las futuras potencias económicas del mundo occidental. Thomas Mun fue uno de aquellos escritores mercantilistas que destacó el papel del comerciante en el auge del sistema mercantilista. El estudio de sus ideas permite concluir que sus recomendaciones acerca de lo que debería ser un comerciante de éxito siguen vigentes hoy en día. La razón de tal afirmación estriba en que sus recomendaciones eran adecuadas en un marco en que se estaba presentando una transformación significativa del sistema de organización comercial con la presencia de la Joint-Stock Company. Independientemente de que muchas de las funciones que Thomas Mun le atribuía al comerciante hoy en día son especializadas, su dominio sigue siendo la clave del éxito de una política comercial que emprenda cualquier nación.

  10. Thomas Willis: the faculties and his two cognitive frameworks.

    2014-11-01

    Thomas Willis' 1664 study The anatomy of the brain is widely regarded as one of the first clinical studies of the brain. In Theanatomy, Thomas Willis explicitly connected the cognitive faculties and the nerves. Willis' later, 1672 work, The two discourses concerning the soul of brutes, severely undermined the materialism of Willis' first study: he affirmed dualism and cognitive immateriality; changed the anatomical locations of cognition; and reasserted a division between the rational and sensitive souls. His exact motive to return to orthodoxy is unclear, but contemporary scholarship of Willis has compounded the confusion with by relying predominantly on The soul of brutes instead of The anatomy. We trace Willis' career and examine his methodological practices, which help explain the historical practices and pressures. A closer examination of Willis' Anatomy of the brain reveals a much more materialistic account of the brain, the faculties, and nervous system. In this article, we present our own analysis of Willis' concept of rationality in the Anatomy and explain its importance for nervous physiology and understanding the analytic techniques for first defining faculty localizations. We then explain the role of the imagination and the immortal soul in the rearticulated anatomical concepts from The soulof brutes. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available All philosophers, beginning with the pre-Socratics, through Plato and Aristotle, and up to Thomas Aquinas, accepted as a certain that the world as a whole existed eternally. The foundation for the eternity of the world was the indestructible and eternal primal building material of the world, a material that existed in the form of primordial material elements (the Ionians, in the form of ideas (Plato, or in the form of matter, eternal motion, and the first heavens (Aristotle. The article outlines the main structure of the philosophical theory of creation ex nihilo developed by St. Thomas Aquinas and indebted to his metaphysical thought. It shows the wisdom-based and ratiocinative foundation of the rational cognition of reality—reality that comes from the personal creative act of God. It concludes that the perception that the beings called to existence by the personal act of God the Creator are intelligible is the ultimate rational justification for the fact that our human cognition, love, and spiritual creativity are rational.

  12. Josef Frank and the history of architecture: Gothic and the Renaissance, Leon Battista Alberti and Albrecht Dürer in the architectural discourse on Neues Bauen at the beginning of the 1930s

    Directory of Open Access Journals (Sweden)

    Caterina Cardemone

    2016-06-01

    Full Text Available The paper focuses on Josef Frank’s convinced use of historiographical arguments in his sharp critique of German modernist architecture. Frank’s attention to architectural history dates back to his education at the Technische Hochschule in Vienna, with Carl König, and the writing of a doctoral thesis on Leon Battista Alberti’s religious buildings in 1910. If a profound knowledge of Alberti’s writings informs Frank’s entire theoretical work, the point discussed here is the parallel between Neues Bauen and Gothic traced by Frank to exclude Neues Bauen from a true modernity, based, on the opposite, on a classical tradition of thought. An attempt is made to reconstruct Frank’s historiographical references and to insert his work in the broader historiographical context, thus highlighting a close link between architectural theory and critique on the one hand and contemporary historiographical constructions on the other.

    Full Text Available RESUMEN En el presente artículo se presentan cuatro claves de lectura de la obra de Thomas Hobbes desde las que fundamentar una noción de resistencia. Este aporte busca, en otras palabras, crear las condiciones de posibilidad de un debate filosófico ofuscado por el mito recurrente sobre el supuesto monstruo de Malmesbury. Una vez hecho esto, se propone delinear las bases de un enfoque metodológico que parta de dicha noción de resistencia. De ese modo, se fundamentaría el primer paso hacia una apropiación ?o expropiación? contemporánea de la matriz hobbesiana de la relación obediencia-seguridad   ABSTRACT This article presents four key of readings about Thomas Hobbes's work, from which it supports a particular notion of resistance. In others words, this contribution searches to create the conditions of posibility for a philosophical debate obfuscated by the recurrent myth about the monster of Malmesbury. Once done that, I offer setting the bases of a metodological aproach which stars from this notion of resistance. Thus, I would back the first step towards a contemporary appropriation ?or expropriation? of the obedience-security relationship within the Hobbesian matrix.

  12. Green leviathan? Thomas hobbes, joel bakan and Arnold schwarzenegger.

    Science.gov (United States)

    Evans, Robert G

    2007-02-01

    Thomas Hobbes postulates that men are driven by "a perpetual and restless desire of power after power, that ceaseth only in death." The miserable consequences of this drive for power and the competing "desire of ease and sensual delight" and "fear of death and wounds" lead them to establish and obey. Substituting "profit" for "power" yields a description of the modern corporation, but without the desires or fears of natural persons. Such "unnatural persons" lack the Hobbesian ground of obligation, yet have appropriated the privileges and protections of natural persons. They challenge or undermine the sovereign wherever it limits their profits. Governor Schwarzenegger's re-election in California, however, on a strong anti-CO(2) program, suggests a willingness by threatened natural persons to re-empower Leviathan.

    The SPIRES database was created in the late 1960s to catalogue the high energy physics preprints received by the SLAC Library. In the early 1990s it became the first database on the web and the first website outside of Europe. Although indispensible to the HEP community, its aging software infrastructure is becoming a serious liability. In a joint project involving CERN, DESY, Fermilab and SLAC, a new database, INSPIRE, is being created to replace SPIRES using CERN's modern, open-source Invenio database software. INSPIRE will maintain the content and functionality of SPIRES plus many new features. I describe this evolution from the birth of SPIRES to the current day, noting that the career of Tony Thomas spans this timeline.

  17. Whistles, bells, and cogs in machines: Thomas Huxley and epiphenomenalism.

    Science.gov (United States)

    Greenwood, John

    2010-01-01

    In this paper I try to shed some historical light upon the doctrine of epiphenomenalism, by focusing on the version of epiphenomenalism championed by Thomas Huxley, which is often treated as a classic statement of the doctrine. I argue that it is doubtful if Huxley held any form of metaphysical epiphenomenalism, and that he held a more limited form of empirical epiphenomenalism with respect to consciousness but not with respect to mentality per se. Contrary to what is conventionally supposed, Huxley's empirical epiphenomenalism with respect to consciousness was not simply based upon the demonstration of the neurophysiological basis of conscious mentality, or derived from the extension of mechanistic and reflexive principles of explanation to encompass all forms of animal and human behavior, but was based upon the demonstration of purposive and coordinated animal and human behavior in the absence of consciousness. Given Huxley's own treatment of mentality, his characterization of animals and humans as "conscious automata" was not well chosen.

  18. "German Culture is where I am": Thomas Mann in Exile

    Directory of Open Access Journals (Sweden)

    Helmut Koopmann

    1982-09-01

    Full Text Available Thomas Mann in exile reacted like many writers expelled from Germany: totally irritated he tried to defend his own identity by claiming that he was still the leading representative of Germany. But about 1938 a process of dissociation from Germany started which led to sharp remarks on Germany in his The Beloved Returns , to his conviction that German culture was where he lived and to the acknowledgement of America as his new home. Traces of his experience of exile, and a late answer on his separation from Germany in 1933, however, are to be found even in his incompleted novel Felix Krull which seems to have turned the disgusting experience of exile into friendly mythological light.

  19. Thomas-Fermi theory for atomic nuclei revisited

    International Nuclear Information System (INIS)

    Centelles, M.; Schuck, P.; Vinas, X.

    2007-01-01

    The recently developed semiclassical variational Wigner-Kirkwood (VWK) approach is applied to finite nuclei using external potentials and self-consistent mean fields derived from Skyrme interactions and from relativistic mean field theory. VWK consists of the Thomas-Fermi part plus a pure, perturbative h 2 correction. In external potentials, VWK passes through the average of the quantal values of the accumulated level density and total energy as a function of the Fermi energy. However, there is a problem of overbinding when the energy per particle is displayed as a function of the particle number. The situation is analyzed comparing spherical and deformed harmonic oscillator potentials. In the self-consistent case, we show for Skyrme forces that VWK binding energies are very close to those obtained from extended Thomas-Fermi functionals of h 4 order, pointing to the rapid convergence of the VWK theory. This satisfying result, however, does not cure the overbinding problem, i.e., the semiclassical energies show more binding than they should. This feature is more pronounced in the case of Skyrme forces than with the relativistic mean field approach. However, even in the latter case the shell correction energy for e.g., 208 Pb turns out to be only ∼-6 MeV what is about a factor two or three off the generally accepted value. As an ad hoc remedy, increasing the kinetic energy by 2.5%, leads to shell correction energies well acceptable throughout the periodic table. The general importance of the present studies for other finite Fermi systems, self-bound or in external potentials, is pointed out

  20. The light bulb, cystoscopy, and Thomas Alva Edison.

    Science.gov (United States)

    Moran, Michael E

    2010-09-01

    Thomas Alva Edison was an icon of American achievement who literally invented the 20th century. Although best known as the inventor of the electric light bulb, the phonograph, and motion pictures, he also left a lasting legacy via peripheral developmental applications, such as endoscopes. A review of published urologic writings about incandescent cystoscopes was cross-referenced to writings about or from Edison. Important events that allowed transference of technology from the Edison laboratory to clinical practice were emphasized. Edison was born in 1847 while Lincoln was serving in Congress; he died in 1931 when Hoover struggled with the Great Depression. Edison's life spanned the formative period of America that Henry Adams called the "coming of age." Edison received a Sprengel vacuum device in late 1879, and as usual, he was able to tweak the machine to better performance. For 5 days in October, 16 to 21, he improved the vacuum from 1/100,000 to 1/1,000,000 atm, and his first incandescent bulb burned softly. On December 21, 1879, he leaked the story to N.Y. Herald journalist Marshall Fox, and the world was notified of the light bulb. Special Christmas light visits started in Menlo Park just 4 days later. Edison patented the screw cap for easy changes, and the first bulbs sold for 40 cents (cost $1.40). 100,000 bulbs sold in 1882, 4 million by 1892, and 45 million in 1903. Immediately, competitors and specialty manufacturers entered the market. Dr. Henry Koch and Charles Preston in Rochester, N.Y., developed a smaller, low amperage bulb that could be fitted to medical devices. No discussion of electricity and modern applications would be complete without some discussion of Thomas Alva Edison and his sentinel contributions. The first church, post office, and ship were illuminated in 1892. The first hotel, theater, and electric sign were in 1893. The rapidity of dispersal and secondary applications of Edison's inventions is typified by the rise of cystoscopes

  1. Obtaining a W state from a Greenberger-Horne-Zeilinger state via stochastic local operations and classical communication with a rate approaching unity.

    Science.gov (United States)

    Yu, Nengkun; Guo, Cheng; Duan, Runyao

    2014-04-25

    We introduce a notion of the entanglement transformation rate to characterize the asymptotic comparability of two multipartite pure entangled states under stochastic local operations and classical communication (SLOCC). For two well known SLOCC inequivalent three-qubit states |GHZ⟩=(1/2)(|000⟩+|111⟩) and |W⟩=(1/3)(|100⟩+|010⟩+|001⟩), we show that the entanglement transformation rate from |GHZ⟩ to |W⟩ is exactly 1. That means that we can obtain one copy of the W state from one copy of the Greenberg-Horne-Zeilinger (GHZ) state by SLOCC, asymptotically. We then apply similar techniques to obtain a lower bound on the entanglement transformation rates from an N-partite GHZ state to a class of Dicke states, and prove the tightness of this bound for some special cases which naturally generalize the |W⟩ state. A new lower bound on the tensor rank of the matrix permanent is also obtained by evaluating the tensor rank of Dicke states.

  2. Greenberger-Horne-Zeilinger-type and W-type entangled coherent states: Generation and Bell-type inequality tests without photon counting

    International Nuclear Information System (INIS)

    Jeong, Hyunseok; Nguyen Ba An

    2006-01-01

    We study Greenberger-Horne-Zeilinger-type (GHZ-type) and W-type three-mode entangled coherent states. Both types of entangled coherent states violate Mermin's version of the Bell inequality with threshold photon detection (i.e., without photon counting). Such an experiment can be performed using linear optics elements and threshold detectors with significant Bell violations for GHZ-type entangled coherent states. However, to demonstrate Bell-type inequality violations for W-type entangled coherent states, additional nonlinear interactions are needed. We also propose an optical scheme to generate W-type entangled coherent states in free-traveling optical fields. The required resources for the generation are a single-photon source, a coherent state source, beam splitters, phase shifters, photodetectors, and Kerr nonlinearities. Our scheme does not necessarily require strong Kerr nonlinear interactions; i.e., weak nonlinearities can be used for the generation of the W-type entangled coherent states. Furthermore, it is also robust against inefficiencies of the single-photon source and the photon detectors

  3. Thomas Hardy, Provincial Geology and the Material Imagination

    Directory of Open Access Journals (Sweden)

    Adelene Buckland

    2008-04-01

    Full Text Available This essay explores the nineteenth-century traffic and exchange of fossils and natural-historical objects between province and metropolis as represented by two very different geological writers of the period, the fossil collector Gideon Mantell and the novelist Thomas Hardy. The men are connected through Mantell's 'The Wonders of Geology', the sixth edition of which (1848 Hardy read and utilised for his descriptions of the geological past in his third novel, 'A Pair of Blue Eyes' (1873. These two texts demonstrate a powerful investment in determining the meaning of the geological object according to the social and geographical spaces in which it is discovered, displayed, and discussed, so that the scientific object becomes the site around which complex cultural politics coalesce and sit in tension. In its consideration of the relationship between place and meaning in science, and in its focus on scientific material culture, this essay attempts to disrupt the current spotlight on the interrelationships between scientific law and narrative pattern in Victorian literary studies. Instead, it hopes to contribute to a discussion of the ways in which the novel's attention to scientific objects rather than narratives made it an important site of epistemological enquiry into the basis of scientific knowledge and the inseparability of that knowledge from the discourses and spaces which produced it.

  4. THEOLOGY AS CREATIVE LANGUAGE. THE CASE OF THOMAS BROOKS

    Directory of Open Access Journals (Sweden)

    Ciprian SIMUȚ

    2015-12-01

    Full Text Available The problem of theological language has been a hindrance in coming closer to God, ever since complex patterns of thought have combined with the theological inquiry. The conclusion that helped Protestantism gain ground was bringing the theological message of the Bible to the understanding of every-day believer. An effort was made to explain how God works in history, and how to become more like Christ in one’s every-day life. However, mere copying was not the foundation of Christianity. Inner conviction born out of understanding the explanation from the Biblical message was crucial. Thomas Brooks was one of the protestant theologians who aimed to explain how the Devil and evil work against the believer, in order to create chaos, disorder, sorrow, hatred, deception, and ignorance. He did this by transforming the theological message into creative language, using every-day images in order to create a relation between theology and praxis. This paper will analyze some of the aspects found in Brooks’ theological presentation, in order to show how theology could be used for the benefit of the individual believer, as well as for the benefit of society.

  5. "The Leviathan" as automaton: method and politics in Thomas Hobbes

    Directory of Open Access Journals (Sweden)

    Diego Fernández Peychaux

    2014-02-01

    Full Text Available This article points out the tension between the normative purpose of Thomas Hobbes’s political texts, and the identification of the resolutive-compositive method of science as it is applied in those texts. In order to solve this difficulty one should appeal to Hobbes’s epistemological texts to read the example of the clock from a new perspective. Thus, if the Hobbesian method responds to the need for normative innovation, it not only denies an apologetic intentionality for a completely ignored historical reality, but also makes it possible to describe the relationship between the individual and the State in a manner different from traditional understandings. According to these conclusions, man ceases to be simply a mechanical part but rather becomes a cause, and therefore, a measure of the effectiveness and functionality of a State. Man’s savage individualism while in the state of nature is not the model, but the cause that justifies a Leviathan capable of turning the homo homini lupus into homo homini deus.

  6. A modified Thomas-Fermi treatment of nuclei

    International Nuclear Information System (INIS)

    Swiatecki, W.J.

    1992-01-01

    An improved nuclear Thomas-Fermi theory is studied in which, rather than adding density-gradient corrections to the standard expression for the kinetic energy density (proportional to ρ 5/3 , where ρ is the density) one simply modifies this ρ 5/3 function to reflect the fact that the kinetic energy density becomes negative for small values of ρ when, in a typical nuclear problem, one is dealing with the outer fringes of the surface region. The net result of this study is simply stated: In order to find the density associated with a given nuclear potential, one exponentiates this potential instead of raising its depth with respect to the chemical potential to the three-halves power, as in the standard treatment. An improved description of the nuclear surface profile is obtained, including the quantal halo in the classically forbidden region. But since density derivatives are not involved, there is no need to solve a partial differential equation in order to find the density. (orig.)

  7. American Connections: The Early Works of Thomas Bang

    Directory of Open Access Journals (Sweden)

    Ring Petersen, Anne

    2015-09-01

    Full Text Available The Danish artist Thomas Bang spent his early years in the USA. The works he created in this formative period were thus profoundly shaped by the contemporary movements in American art of the 1960s and 1970s when sculpture, or to be more precise, three-dimensional work became a hotbed of expansive experiments. This article traces how Bang made a radical move from painting to sculpture, which was characteristic of that time, and how he developed his artistic idiom by taking an active part in some of the seminal new departures in American art, in particular process art and post-minimalism. By leaping forward to Bang's later works produced after his return to Denmark, the article also demonstrates how the sculptural syntax and working principles developed in the early works still underlie and structure the artist's more allegorical sculptures and installations from the 2000s, thus testifying to the lasting impact of Bang's American period, which remains the key to understanding his works.

  8. An improved Thomas--Fermi treatment of nuclei

    Swiatecki, W.J.

    1992-01-01

    I want to tell you about an improved Thomas-Fermi method for calculating shell-averaged nuclear properties, such as density distributions, binding energies, etc. A shell-averaged statistical theory is useful as the macroscopic component of microscopic-macroscopic theories of nuclei, such as the Strutinsky method, as well as in theories of nuclear matter in the bulk, relevant in astrophysical applications. In nuclear physics, as well as in atomic and molecular problems, the following question often has to be answered: you are given a potential well, say a deformed Woods-Saxon potential, into which you put N quantized fermions into the lowest N eigenstates, up to a ''Fermi energy'' To. You square the wave functions of the particles and add them up to get the total density ρ( r → ) = Σ i N |ψ i | 2 . Is there some simple way of estimating ρ( r → ) without going through the misery of numerically solving N partial differential Schroedinger equations for the N particles?

  9. Nietzche's echo--a dialogue with Thomas Altizer.

    Science.gov (United States)

    Moss, David M

    2010-03-01

    Prophets provoke psychological unrest, especially when exposing accepted beliefs as profound deceptions. The biblical prophets exemplify such confrontation as do certain atheists ardently opposed to the images of God created by those seers. The German philosopher Friedrich Nietzsche dramatically illustrates this type of counterforce to the Judeo-Christian tradition. His prophet Zarathustra is intended to be a model for the modern mind, one free of superstitions inflicted by antiquated religious dogma. Nietzsche's credo "God is dead" served as a declaration for the nineteenth century. In the twentieth century, it became a theological diagnosis. As a "movement," or "tenor," the death of God or radical theology was spearheaded by Thomas Altizer, a well-published young professor center-staged during the turbulent 1960s. His work foreshadows a new strain of atheism currently represented by biologist Richard Dawkins (2006, The God delusion. New York: Houghton Mifflin), philosopher Daniel Dennett (2006, Breaking the spell. New York: Penquin), neuroscientist Sam Harris (2004, The end of faith. New York: W.W. Norton; 2008, Letter to a Christian nation. New York: Vintage), journalist Christopher Hitchens (2007, God is not great. New York: Twelve), and mathematician John Allen Paulos (Paulos 2008, Irreligion. New York: Hill & Wang). This twenty-first century crusade against belief in God is best understood as a psychodynamic ignited by Altizer's Christian atheism. The present dialogue reflects that dynamic while the prologue and epilogue reveal evidence of Providence amidst claims of God's demise in contemporary history.

    To assess the usefulness of percutaneous treatment of abnormalities of the venous tree in extending the survival of external Thomas shunts (TS). Twelve cases of TS were included in a hemodialysis access fistula dysfunction monitoring program and were followed for up to 48 months. The abnormalities found were treated by percutaneous transluminal angioplasty (PTA) or thrombolysis and PTA. Survival curves and the Kaplan-Meier method were used to calculate the likelihood of primary patency (P1), secondary patency (P2), and overall patency (OP). A total of 61 interventions were performed during the period of follow-up. On 12 occasions the fistula was thrombosed; in the rest, increased venous pressure to 150 mmHg or higher was detected during dialysis. Fistulography was performed after washing the thrombosed fistulas with urokinase, and revealed one or more of the following angiographic signs: 1) a short reduction of more than 50% in lumen caliber in the femoral vein adjacent to the anastomosis, present in 52% of the cases (fig. 1); 2) imaging a "jet" of contrast material at the site of entry of the shunt into the femoral vein (fig. 2), present in 22% of the cases; and 3) a filling defect or "flap" at the same site, owing to hyperplastic tissue or piece of thrombus adhering to the intima, present in 34% of the cases (figs. 3-5). This last-mentioned finding ordinarily gave rise to a "valve" effect, whereby injection into the venous branch was feasible but aspiration from the venous branch was difficult or impossible. PTA was carried out and attained anatomical and functional success in 100% of cases. PI was 58%, 33%, 8%, and 0% at 6, 12, 24, and 36 months, respectively; P2 was 100%, 75%, 58%, and 25%; respectively, at those same times. The comparison of the PI and P2 curves was statistically significant; p < 0.001 (table 1). OP was 83%, 66%, 50% and 41% at 12, 24, 36 and 48 months. The comparison of the PI surgical and OP curves was statistically significant; p < 0

    Llewellyn Hilleth Thomas was born in 1903 and died in 1992 at the age of 88. His name is known by most for only two things, Thomas precession and the Thomas-Fermi atom. The many other facets of his career - astrophysics, atomic and molecular physics, nonlinear problems, accelerator physics, magnetohydrodynamics, computer design principles and software and hardware - are largely unknown or forgotten. I review his whole career - his early schooling, his time at Cambridge, then Copenhagen in 1925-26, and back to Cambridge, his move to the US as an assistant professor at Ohio State University in 1929, his wartime years at the Ballistic Research Laboratory, Aberdeen Proving Grounds, then in 1946 his new career as a unique resource at IBM's Watson Scientific Computing Laboratory and Columbia University until his first retirement in 1968, and his twilight years at North Carolina State University. Although the Thomas precession and the Thomas-Fermi atom may be the jewels in his crown, his many other accomplishments add to our appreciation of this consummate applied mathematician and physicist. )

    There are many cardioplegia solutions currently in use for pediatric cardiopulmonary bypass (CPB). The most common being del Nido solution. Another common cardioplegia solution used for pediatric CPB is St. Thomas. In October 2014, Children's Mercy Kansas City changed from the use of modified St. Thomas to del Nido. This study compared rates of post cross-clamp fibrillation requiring defibrillation between del Nido solution and modified St. Thomas solution stratified by weight at Children's Mercy Kansas City. This retrospective study consisted of 394 patients who underwent cardiac surgery requiring cardioplegia between January 1, 2014 and July 31, 2015. The outcome measured was defibrillation upon cross-clamp removal. Statistical significance was determined using Fishers exact test with a two-sided significance level of .05. Incidence of defibrillation post cross-clamp removal was 4.4% in the del Nido group and 26.8% in the St. Thomas group (p Thomas group (p Thomas group (p Thomas group (p 60-kg category had an incidence of defibrillation of 16.7% in the del Nido group and 63% in the St. Thomas group (p Thomas and del Nido cardioplegia solutions. Analyses of weight stratifications demonstrate a decrease in the rate of defibrillation post cross-clamp removal in all categories within the del Nido group.

  11. Obituary: Thomas C. Van Flandern (1940-2009)

    Science.gov (United States)

    Dunham, David; Slabinski, Victor

    2011-12-01

    Dr. Thomas Charles Van Flandern, an expert in celestial mechanics and cosmology, died January 9, 2009 in Seattle, Washington, of colon cancer. He was 68. Van Flandern was an astronomer at the U.S. Naval Observatory from 1963 to 1983. He developed software to predict and analyze lunar occultations to improve lunar orbital and fundamental star catalog data. In later years he championed increasingly controversial theories. But his 1978 prediction that some asteroids have natural satellites, which was almost universally rejected, was verified when the Galileo spacecraft photographed Dactyl, a satellite of (243) Ida, during its flyby in 1993. Besides astronomy and computers, he had strong interests in biochemistry and nutrition, and he ran a business selling personal computers in the 1980s. Tom Van Flandern was born June 26, 1940 in Cleveland, Ohio, the first child of Robert F. Van Flandern and Anna Mary Haley. His father, a police officer, left the family when Tom Van Flandern was 5. His mother died when he was 16; he and his siblings then lived with their grandmother, Margery Jobe, until he went to college. Tom Van Flandern became interested in astronomy as a child. He used his first telescope, purchased with newspaper delivery earnings, to observe lunar occultations, and then learned how to predict them, sparking a life-long passion for dynamical astronomy. While attending St. Ignatius High School, Van Flandern and fellow student Thomas Petrie organized the Cleveland Moonwatch team to observe the first artificial satellites, the only team without an adult organizer. In 1958, Tom Van Flandern entered Xavier University where he led the Cincinnati Moonwatch team. He learned computer programming at a summer job with General Electric and wrote software to calculate "look angles" from orbital elements. The Cincinnati team became a top producer of observations using these predictions. Tom obtained a B.S. in mathematics from Xavier in 1962. He spent the next year at

  12. A relativistic extended Fermi-Thomas-like equation for a self-gravitating system of fermions

    International Nuclear Information System (INIS)

    Merloni, A.; Ruffini, R.; Torroni, V.

    1998-01-01

    The authors extend previous results of a Fermi-Thomas model, describing self-gravitating fermions in their ground state, to a relativistic gravitational theory in Minkowski space. In such a theory the source term of the gravitational potential depends both on the pressure and the density of the fluid. It is shown that, in correspondence of this relativistic treatment, still a Fermi-Thomas-like equation can be derived for the self-gravitating system, though the non-linearities are much more complex. No Fermi-Thomas-like equation can be obtained in the General Relativistic treatment. The canonical results for neutron stars and white dwarfs are recovered and also some erroneous statements in the scientific literature are corrected

  13. The Ecclesiological Contributions of Thomas Helwys’s Reformation in a Baptist Context

    Directory of Open Access Journals (Sweden)

    Jones Marvin

    2017-12-01

    Full Text Available The English Separatist movement provided the background for which John Smyth and Thomas Helwys emerged to reconstitute a biblical ecclesiology. Through the study of the New Testament, they came to the position that infant baptism and covenantal theology could not be the foundation for the New Testament church. Both men embraced believer’s baptism as the basic foundation in which a recovered church should be built. Unfortunately, Smyth defected to the Mennonites, leaving Thomas Helwys to continue the fledging work known as Baptists. This article will examine the life of Thomas Helwys and his contribution to Baptist ecclesiology; it will also review selected literary works that contributed to the recovery of a New Testament church and the founding of Baptist ecclesiology.

  14. Jude the Obscure de Thomas Hardy et l’autorité de la lettre Jude the Obscure by Thomas Hardy and the Power of the Letter

    Directory of Open Access Journals (Sweden)

    Stéphanie Bernard

    2009-10-01

    Full Text Available Thomas Hardy is usually considered a Victorian writer. Nonetheless, his last novel Jude the Obscure, announced the era of modernity which started with the twentieth century, just before he abandoned fiction to concentrate on poetry. With modernity looming in the background, Jude the Obscure allowed for the rewriting of tragedy. Urban settings have replaced the countryside and all signs of transcendence have vanished from society. This defeat of the divine is nevertheless accompanied by a great number of biblical references. Thomas Hardy quotes and uses the Divine Letter as if to rewrite it rather than to appear faithful to the Word. The text keeps offering itself to the spell of voice: it does so when Job utters words of revolt and then worship, when Jude lets his imagination flow from his lips so that he seems to live on in the text after he is dead, or when the voice of the novelist becomes the voice of a poet.

  17. Derivation of the Euler equations in Thomas-Fermi theories of a hot nuclear system

    International Nuclear Information System (INIS)

    Wang, C.

    1992-01-01

    The variational extreme condition with respect to statistical distribution of nucleons in momentum space is applied to derive the Euler equation of the nuclear density profile. The resultant Euler equation of the nuclear density profile is proven to be identical with that obtained in the usual Thomas-Fermi theories of a hot nuclear system where the variation is made with respect to the nuclear density profile. A Fermi-Dirac-type distribution appears as a result of variation in the present approach, while it is used as a given expression in obtaining the variation of the nuclear density profile in the usual Thomas-Fermi theories

    2004-01-01

    A simple semiclassical approach, based on the investigation of anti-Stokes line topology, is presented for calculating Regge poles for nonsingular (Thomas-Fermi type) potentials, namely potentials with singularities at the origin weaker than order -2. The anti-Stokes lines for Thomas-Fermi potentials have a more complicated structure than those of singular potentials and require careful application of complex analysis. The explicit solution of the Bohr-Sommerfeld quantization condition is used to obtain approximate Regge poles. We introduce and employ three hypotheses to obtain several terms of the Regge pole approximation

    2017-11-01

    Peter of Tilleberi (Tilbury), later known as bishop Thomas of Wroclaw, after completing his studies (in Bologna or in Montpellier) worked as a physician in northern Italy and probably in Spain. Later through Germany and Bohemia, he came to Wroclaw in 1336 where he joined the Order of St. Dominic. In 1352, Thomas was made an auxiliary bishop of the diocese of Wroclaw. After the episcopal consecration, Thomas stopped living in the abbey, but all the time he was well known both as a priest and physician. He is known as an author of several treatises on medical sciences. His most important work entitled Michi competit (i.e. It suits me) is composed of four parts: Regimen sanitatis (i.e. Hygiene), Aggregatum (i.e. Aggregation), Antidotarium (i.e. Medicine directory) and Practica medicinalis (i.e. Medical practices). Moreover, he is the author of other treatises including, for example, De phlebotomia et de iudiciis cruoris (i.e. On phlebotomy and blood content) and De urinis (i.e. On urine). Some Polish scientists claim that bishop Thomas of Wroclaw with his knowledge and industriousness functioned as a university faculty of medicine even though the University of Cracow had not been established yet.

  7. The poor in the Epistle of James and the Gospel of Thomas

    Directory of Open Access Journals (Sweden)

    Patrick J. Hartin

    1997-12-01

    Full Text Available This study explores similarities in the thought world of the Epistle of James and the Gospel of Thomas. Particular attention is devoted to the role that the 'poor' and 'poverty' play in both documents. For the Epistle of James it is 'the poor in the world that God has chosen to be rich in faith and heirs of the kingdom' (Ja 2:5.  In a similar vein, in the Gospel of Thomas the kingdom is promised to those who have embraced the poverty of a radical life-style: 'Blessed are the poor, for yours is the kingdom of heaven' (GTh 54. This outlook betrays a basic ethos adopted toward the world. In both the Epistle of James and the Gospel of Thomas the relationship to the world ultimately determines one's relationship to the kingdom or to God. For the Epistle of James the very definition of religion demands that one keep 'oneself unstained from  the world' (Ja 1 :27 and that 'friendship with the world' is enmity with God (Ja 4:4. For the Gospel of Thomas the rejection of the world involves a radical ethos that embraces an intinerant life ('Be passersby' [GTh 42J, which includes a rejection of wealth (GTh 63.'If you do not abstain from the world, you will not find the kingdom' (GTh 27. It is argued that the Gospel of Thomas and the Epistle of James reflect traditional sayings that endorse a similar ethos of radical discipleship.

  10. Thomas Mann's "Tobias Mindernickel" in Light of Sartre's "Being-for-Others"

    Directory of Open Access Journals (Sweden)

    Beth Bjorklund

    1978-01-01

    Full Text Available Sartre's analysis of "Being-for-Others" in Being and Nothingness describes the Self-Other relationship as essentially one of conflict, with the Self attempting either to dominate or to be dominated by the Other. Subject-Object relations are a common theme also in the early works of Thomas Mann, who gives artistic expression to many of the same problems which Sartre later formalized in a philosophical theory. The sado-masochistic character, which is portrayed in several of Thomas Mann's narratives, receives its strongest expression in the story "Tobias Mindernickel," which is here singled out for analysis. Humiliation gives rise to aggression, as the protagonist feels both an attraction and a repulsion for his surrogate lover, a dog. The interpersonal relationships revealed here serve as paradigmatic illustration of Sartre's theory of "Concrete Relations with Others."

  11. Thomas-Fermi treatment of nuclear masses, deformations and density distributions

    International Nuclear Information System (INIS)

    Myers, W.D.; Swiatecki, W.J.

    1994-08-01

    A recently completed Thomas-Fermi model of nuclei is described. Six adjustable parameters of the effective nucleon-nucleon interaction were fitted to the shell-corrected binding energies of 1654 nuclei and to the diffuseness of the nuclear surface. The model is then successful in reproducing nuclear sizes, and only small deviations are found between calculated and measured fission barriers of 36 nuclei. The model is applied to the prediction of fission barriers of light elements, to drip-line nuclei like 82 Sn and 170 Sn, to the properties of nuclear and neutron matter and to nuclear bubble configurations with Z 2 /A ∼ 100. The relation of a Thomas-Fermi theory to the Droplet and Liquid Drop models is illustrated

  12. Two-centre interference effects on the Thomas two-step scattering mechanisms

    International Nuclear Information System (INIS)

    Adivi, E Ghanbari

    2010-01-01

    The charge transfer process in the collision of fast protons with hydrogen molecules is theoretically investigated using the second-order Born approximation with correct boundary conditions. In addition to two first-order terms, the present calculations include the three second-order terms which correspond to the Thomas two-step scattering mechanisms. The interference effects, due to the scattering of the particles from two atomic centres, on the electron capture differential cross sections vary significantly with the orientation of the molecule and with the impact energy. After the averaging over all molecular orientations the interference patterns disappear but the Thomas peak becomes more pronounced. These patterns are also apparent in the differential cross sections as a function of the angle between the molecular axis and the incident beam direction. The integrated cross sections are calculated and the results are compared with available experimental data.

  14. Thomas Kuhn's revolutions a historical and an evolutionary philosophy of science?

    CERN Document Server

    Marcum, James A

    2015-01-01

    This new edition of Thomas Kuhn's Revolution marks the 50th anniversary of the publication of Kuhn's most influential work. Drawing on the rich archival sources at MIT, and engaging fully with current scholarship, James Marcum provides the historical background to the development of The Structure of Scientific Revolutions. Exploring the shift Kuhn makes from a historical to an evolutionary philosophy of science and examining Kuhn's legacy in depth, Marcum answers key questions: What exactly was Kuhn's historiographic revolution and how did it come about? Why did it have the impact it did? What will its future impact be for both academia and society? Marcum's answers build a new portrait of Kuhn: his personality, his pedagogical style and the intellectual and social context in which he practiced his trade. Thomas Kuhn's Revolution shows how Kuhn transcends the boundaries of the philosophy of science, influencing sociologists, economists, theologians and even policy makers and politicians. This is a comprehensi...

  15. Thomas Aquinas on the Soul: Old problems, New Solutions. Guiding Premises for a Thomistic Synthesis

    Directory of Open Access Journals (Sweden)

    Yevgeniy Shilov

    2012-12-01

    Full Text Available This article examines two main approaches to the doctrine of the soul: that of Plato and that of Aristotle. Each of these approaches had its own development and its own interpretations. Plato and his school was more important during the Middle Ages. Through the neo-platonic philosophers it reached Saint Augustine and became a part of the western cultural and religious heritage until finally it was taken up by member of the Franciscan order - Roger Bacon and Bonaventure. But this paradigm could not solve a host of problems connected with the soul and many of them remained unresolved. The end of the twelfth century brought the growth of the universities and the teaching of Aristotle - a new paradigm - transmitted by the Arabic philosophers which was rediscovered by the West. Two commentators on Aristotle - Averroes and Avicenna -were the most important for the West, especially since Avicenna exerted a great influence on Albert the Great. But both Plato and Aristotle, when taken separately, proved to be quite useless in resolving certain problems. But Thomas Aquinas was able to splice the Gordian knot concealing a solution to the problem of the soul. By combining the psychology of Plato with the metaphysics of Aristotle, Thomas succeeded in creating a new concept of the human person. The author of this article has tried to explain the difficulties which faced Thomas and the way in which Thomas was able to resolve a problem which had troubled philosophy through the ages - the problem of reconciling Plato with Aristotle and finding a way to make their conflicting philosophies agree with each other

    We study the ionization problem in the Thomas-Fermi-Dirac-von Weizsäcker theory for atoms and molecules. We prove the nonexistence of minimizers for the energy functional when the number of electrons is large and the total nuclear charge is small. This nonexistence result also applies to external potentials decaying faster than the Coulomb potential. In the case of arbitrary nuclear charges, we obtain the nonexistence of stable minimizers and radial minimizers.

At the dawn of the thirteenth century, the townspeople of Medieval West created a new institution designed for knowledge and education: the University. In it, teachers and disciples were debating key issues for the new society using mainly texts of Ancient Philosophy and Christians, but also Arab and Jewish writings. The literacy forms used encompassed mainly lectio and disputatio , and counteracted by distinct theoretical bases, those thinkers eventually recreated the summa , in a original and fundamental form to the philosophical elaboration of that time. To discuss the importance of reading in the formulation of the concept of ethics in the medieval university, we will present some characteristics of the production of knowledge in the thirteenth century linked to its historical context and then discuss some ethical considerations of Thomas Aquinas, one of the most prominent authors of that period. Considering the limits of this article, only one text, “The object of charity” based on Aquinas major work, the Summa of Theology, will be discussed in depth. Preliminarily, it is possible to state that as well as the reading of classical authors by Thomas Aquinas and other masters of the thirteenth century, helped them develop knowledge about ethics conforming to their time, historical reading of these authors helps in the understanding of today.

    Our colleagues at the Sociedade Brasileira de Medicina Tropical have been informed of the demise of Professor Pierre Ambroise-Thomas (1937-2014). However, considering that the tribute we paid to him in 2015 - at the 20th anniversary of the Seminário Laveran & Deane sobre Malária - is equally true today, it is worth sharing it with the readers of the RSBMT, in recognition of his many virtues. Pierre Ambroise-Thomas (MD in 1963 and DSc in 1969) was Honorary Professor of Parasitology and Tropical Medicine at the Faculté de Médecine de Grenoble (France), Honorary President of the Académie Nationale de Médecine, member of the Académie Nationale de Pharmacie and Officier dans l'Ordre de La Légion d'Honneur. In addition to his important contributions to tropical medicine and parasitology, working in France during his long and productive career (50 years and 300 publications), Ambroise-Thomas became an admirer and supporter of Brazilian activities related to research, teaching and information in Tropical Medicine.

    The linear and nonlinear properties of dust-acoustic waves are investigated in a collisionless Thomas-Fermi magnetoplasma, whose constituents are electrons, ions, and negatively charged dust particles. At dust time scale, the electron and ion number densities follow the Thomas-Fermi distribution, whereas the dust component is described by the classical fluid equations. A linear dispersion relation is analyzed to show that the wave frequencies associated with the upper and lower modes are enhanced with the variation of dust concentration. The effect of the latter is seen more strongly on the upper mode as compared to the lower mode. For nonlinear analysis, we obtain magnetized Korteweg-de Vries (KdV) and Zakharov-Kuznetsov (ZK) equations involving the dust-acoustic solitary waves in the framework of reductive perturbation technique. Furthermore, the shock wave excitations are also studied by allowing dissipation effects in the model, leading to the Korteweg-de Vries-Burgers (KdVB) and ZKB equations. The analysis reveals that the dust-acoustic solitary and shock excitations in a Thomas-Fermi plasma are strongly influenced by the plasma parameters, e.g., dust concentration, dust temperature, obliqueness, magnetic field strength, and dust fluid viscosity. The present results should be important for understanding the solitary and shock excitations in the environments of white dwarfs or supernova, where dust particles can exist.

  4. The modified Thomas test is not a valid measure of hip extension unless pelvic tilt is controlled

    Full Text Available The modified Thomas test was developed to assess the presence of hip flexion contracture and to measure hip extensibility. Despite its widespread use, to the authors’ knowledge, its criterion reference validity has not yet been investigated. The purpose of this study was to assess the criterion reference validity of the modified Thomas test for measuring peak hip extension angle and hip extension deficits, as defined by the hip not being able to extend to 0º, or neutral. Twenty-nine healthy college students (age = 22.00 ± 3.80 years; height = 1.71 ± 0.09 m; body mass = 70.00 ± 15.60 kg were recruited for this study. Bland–Altman plots revealed poor validity for the modified Thomas test’s ability to measure hip extension, which could not be explained by differences in hip flexion ability alone. The modified Thomas test displayed a sensitivity of 31.82% (95% CI [13.86–54.87] and a specificity of 57.14% (95% CI [18.41–90.10] for testing hip extension deficits. It appears, however, that by controlling pelvic tilt, much of this variance can be accounted for (r = 0.98. When pelvic tilt is not controlled, the modified Thomas test displays poor criterion reference validity and, as per previous studies, poor reliability. However, when pelvic tilt is controlled, the modified Thomas test appears to be a valid test for evaluating peak hip extension angle.

    Full Text Available Abstract : To establish an argumentation for the existence of God is properly the most crucial as well as complicated effort in the life of religion and faith of human being. There are various approaches and methods have been applicated to reach it by theologians, thinkers, and scientists, including philosophers with their demonstrative-philosophical method. Some arguments which were initiated by Aristotle are ones of the most popular and have been adopted and improved as well by many thinkers and philosophers after him, some arguments which proposed by Ibn Rusyd and St. Thomas Aquinas with some modifications and improvisations are the best examples of it. In the case of elaboration and analysis toward those arguments for the existence of God, this article attempts to compare between metaphysical thought of Ibn Rushd (well-known in the West as Averroës and St. Thomas Aquinas. There is no doubt that both are Aristotelian in their philosophy. Therefore, to seek the similarities and differences, and to analyze the influence of Aristotle on their modes of thought, especially in argumentation for the existence of God, are an urgent point in the way to find more stronger and relevant arguments.Keywords: argument of creation (dalīl al-ikhtirā`, teleological argument (dalīl al-‘ināyah, unmoved mover, prime cause, influence, parallelism.Abstrak : Menggagas argumentasi tentang eksistensi Tuhan sejatinya merupakan upaya yang paling krusial sekaligus pelik dalam kehidupan beragama dan kepercayaan umat manusia.

    The emission widths Γ n and Γ p for emission of neutrons and protons are calculated within the Thomas-Fermi model, which we have recently developed, and are compared with those obtained in the usual Weisskopf approach for the case of zero angular momentum. Both methods yield quite similar results at small deformations, but rather important differences are observed for very deformed shapes, in particular for charged particles. A possible generalization of the model for emission of α-particles is also discussed. (author)

    In quark models a la Bakamjian and Thomas, that yield covariance and Isgur-Wise scaling of form factors in the heavy quark limit, the decay constants f (n) and f 1/2 (n) of S-wave and P-wave mesons composed of heavy and light quarks are computed. Different Ansaetze for the dynamics of the mass operator at rest are discussed. Using phenomenological models of the spectrum with relativistic kinetic energy and regularized short distance part the decay constants in the heavy quark limit are calculated. The convergence of the heavy quark limit sum rules is also studied. (author)

    Partial genome segments of a begomovirus were previously amplified from Wissadula amplissima exhibiting yellow-mosaic and leaf-curl symptoms in the parish of St. Thomas, Jamaica and this isolate assigned to a tentative begomovirus species, Wissadula golden mosaic St. Thomas virus. To clone the complete genome of this isolate of Wissadula golden mosaic St. Thomas virus, abutting primers were designed to PCR amplify its full-length DNA-A and DNA-B components. Sequence analysis of the complete begomovirus genome obtained, confirmed that it belongs to a distinct begomovirus species and this isolate was named Wissadula golden mosaic St. Thomas virus-[Jamaica:Albion:2005] (WGMSTV-[JM:Alb:05]). The genome of WGMSTV-[JM:Alb:05] is organized similar to that of other bipartite Western Hemisphere begomoviruses. Phylogenetic analyses placed the genome components of WGMSTV-[JM:Alb:05] in the Abutilon mosaic virus clade and showed that the DNA-A component is most closely related to four begomovirus species from Cuba, Tobacco leaf curl Cuba virus, Tobacco leaf rugose virus, Tobacco mottle leaf curl virus, and Tomato yellow distortion leaf virus. The putative Rep-binding-site motif in the common region of WGMSTV-[JM:Alb:05] was observed to be identical to that of Chino del tomate virus-Tomato [Mexico:Sinaloa:1983], Sida yellow mosaic Yucatan virus-[Mexico:Yucatan:2005], and Tomato leaf curl Sinaloa virus-[Nicaragua:Santa Lucia], suggesting that WGMSTV-[JM:Alb:05] is capable of forming viable pseudo-recombinants with these begomoviruses, but not with other members of the Abutilon mosaic virus clade. Biolistic inoculation of test plant species with partial dimers of the WGMSTV-[JM:Alb:05] DNA-A and DNA-B components showed that the virus was infectious to Nicotiana benthamiana and W. amplissima and the cultivated species Phaseolus vulgaris (kidney bean) and Lycopersicon esculentum (tomato). Infected W. amplissima plants developed symptoms similar to symptoms observed under field

    In his long and eventful life, Edward Gantt (1742-1837) made important contributions to the newly independent American Republic, as well as to the development of scientific evidence-based American medicine. Unfortunately, his achievements have gone unrecognized and unreported in mainstream historical publications. Specifically, his service as the first designated White House doctor, and personal physician to President Thomas Jefferson from 1801 to 1809 has not been reported. The purpose of this paper is to document the biographical and scientific details of his extraordinary life and notable contributions.

    1999-01-01

    The properties of warm symmetric and asymmetric nuclear matter are investigated in the frame of the Thomas-Fermi approximation using a recent modern parameterization of the effective nucleon-nucleon interaction of Myers and Swiatecki. Special attention is paid to the liquid-gas phase transition, which is of special interest in modern nuclear physics. We have determined the critical temperature, critical density and the so-called flash temperature. Furthermore, the equation of state for cold neutron star matter is calculated. (orig.)

    1978-01-01

    A equation of state for neutron gas, based on Thomas-Fermi model, is used to recalculate the maximum mass of neutron stars. The complete equation of state is found to present a first order phase transition between the subnuclear regime without free neutron and the nuclear regime. This suggests that the sudden disintegration of the neutron-rich-nuclei may be very competitive with relation to the continuous neutron drip process. The mass limit for neutron stars was found to be 3.26 M 0 [pt

  20. The Being in Thomas Aquinas and Hegel from Cornelio Fabro’s perspective

    Directory of Open Access Journals (Sweden)

    Christian BENAVIDES

    2015-02-01

    Full Text Available The names of Thomas Aquinas and Hegel have a prominent place in the history of philosophy. Their metaphysical conceptions rise as two large monuments that summarize the whole culture and thought of an Era. Cornelio Fabro considers that they both have two clearly defined speculative positions which deserve special confrontation with regard to the central problem of Metaphysics: the problem of Being. The present paper aims to show the innovative interpretation of these two great authors made by the Italian philosopher, in order to re-evaluate his exegesis and speculative reflection.
