description: Experimental and theoretical evidence is presented for new low-magnetic-field ($B<5$ kG) 1/B-oscillations in the thermoelectric power of a high-mobility GaAs/AlGaAs two-dimensional (2D) electron gas. The oscillations result from inter-Landau-Level resonances of acoustic phonons carrying a momentum equal to twice the Fermi wavenumber at $B = 0$. Numerical calculations show that both 3D and 2D phonons can contribute to this effect.

How massive are the superfluid cores in the Crab and Vela pulsars and why their glitch-events are accompanied with under and overshootings?

description: The Crab and Vela are well-studied glitching pulsars and the data obtained sofar should enable us to test the reliability of models of their internal structures. Very recently it was proposed that glitching pulsars are embedded in bimetric spacetime: their incompressible superfluid cores (SuSu-cores) are embedded in flat spacetime, whereas the ambient compressible and dissipative media are enclosed in Schwarzschild spacetime. In this letter we apply this model to the Crab and Vela pulsars and show that a newly born pulsar initially of $1.25\text{M}_{\odot}$ and an embryonic SuSu-core of $0.029\text{M}_{\odot}$ could evolve into a \ARZL{Crab-like}\ARZR pulsar after 1000 years and into a \ARZL{Vela-like}\ARZR pulsar 10000 years later to finally fade away as an invisible dark energy object after roughly 10 Myr. Based thereon we infer that the Crab and the Vela pulsars should have SuSu-cores of $0.15\text{M}_{\odot}$ and $0.55\text{M}_{\odot}$, respectively. Futhermore, the under- and overshootings phenomena observed to accompany the glitch events of the Vela pulsar are rather a common phenomenon of glitching pulsars that can be well-explained within the framework of bimetric spacetime.

In order to test if such a discrepancy is originated from the large perturbative corrections to the hard-scattering amplitude, we study inclusive production of four charm hadrons in e^+e^- annihilation at B factories.

description: In this work we present the isovector flavor combination for the nucleon tensor charge extracted from lattice QCD simulations using overlap fermions on $N_f=2+1$ domain-wall configurations. The pion mass dependence is studied using six valence quark masses, each reproducing a value for the pion mass in the valence sector between 147 and 330 MeV. We investigate and eliminate systematic uncertainties due to contamination by excited states, by employing several values for the source-sink separation that span from 1 fm to 1.6 fm. We apply a chiral extrapolation in the valence sector using a quadratic and a logarithmic term to fit the pion mass dependence, which describes well the lattice data. The lattice matrix element is renormalized non-perturbatively, and the final result is $g_T=1.096(30)$ in the $\overline{\rm MS}$ scheme at a renormalization scale of 2 GeV.

The growth mechanism was analyzed and interpreted by means of thermogravimetric analysis. At 300 K, electrical resistivity r and thermoelectric power S of the whisker are 102 u ohm cm and 83 uV/K, respectively. The power-factor, S2/r, thus is enhanced up to ~ 68 uW/K2 cm.

Relativistic Spinor Dynamics Inducing the Extended Lorentz-Force-Like Equation

Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The special relativistic dynamical equation of the Lorentz force type can be regarded as a consequence of a succession of space-time dependent infinitesimal Lorentz transformations as shown by one of us \cite{buitrago} and discussed in the introduction below. Such an insight indicates that the Lorentz-force-like equation has an extremely fundamental meaning in physics. In this paper we therefore present a set of dynamical Weyl spinor equations {\em inducing} the extended Lorentz-force-like equation in the Minowski space-time. The term extended refers to the dynamics of some additional degrees of freedom that may be associated with the classical spin namely with the dynamics of three space-like mutually orthogonal four-vectors, all of them orthogonal to the linear four-momentum of the object under consideration.

description: We consider a computational problem where the goal is to approximate the maximum eigenvalue of a two-local Hamiltonian that describes Heisenberg interactions between qubits located at the vertices of a graph. Previous work has shed light on this problem's approximability by product states. For any instance of this problem the maximum energy attained by a product state is lower bounded by the Max Cut of the graph and upper bounded by the standard Goemans-Williamson semidefinite programming relaxation of it. Gharibian and Parekh described an efficient classical approximation algorithm for this problem which outputs a product state with energy at least 0.498 times the maximum eigenvalue in the worst case, and observe that there exist instances where the best product state has energy 1/2 of optimal. We investigate approximation algorithms with performance exceeding this limitation which are based on optimizing over tensor products of few-qubit states and shallow quantum circuits. We provide an efficient classical algorithm which achieves an approximation ratio of at least 0.53 in the worst case. We also show that for any instance defined by a 3- or 4-regular graph, there is an efficiently computable shallow quantum circuit that prepares a state with energy larger than the best product state (larger even than its semidefinite programming relaxation).

title: The Role of Trust Perceptions and Propensity to Trust in Applicants' Experience of Recruitment and Selection
Creators: name: Patent, Volker
Publisher: name: The Open University
Year: 2015

description: The role of organisational trustworthiness, propensity to trust and distrust was examined in the context of recruitment and selection. Specifically this research aimed to explore applicant experiences of selection as a context for trust. Because there has previously been little work looking systematically at the factorial and construct validity of propensity to trust this study also analysed responses to nine previously published propensity-to-trust scales using a combination of factor analytic, regression and content analyses. Findings supported the idea that propensity to trust scales are multidimensional and reflect aspects of both personality and experience of different trust contexts. The implication of this is that while use of propensity to trust is theoretically justified, checks on dimensionality should be carried out to account for different facets of this construct. The second study used the NEO propensity to trust scale (Costa & McCrae, 1985) as part of a survey looking into research degree applicant's experience of the recruitment and selection process during the post application and post interview stage. In addition to propensity to trust and propensity to distrust playing different role during attraction, influencing the decision of applicants to pursue a vacancy, propensity to distrust also appeared to regulate the relationship between selection justice, organisational trustworthiness and outcome intentions. Evidence from template analysis suggested ways in which justice and trust are manifested during the selection process, but based on a triangulated view, questions about what or whom applicants trust may need further examination and consideration in future research.

description: The anomaly-anomaly correlator is studied using QCD sum rules. Using the matrix elements of anomaly between vacuum and pseudoscalars $π, eta$ and $η'$, the derivative of correlator $chi'(0)$ is evaluated and found to be $\approx 1.82 \times 10^{-3}$ GeV$^2$. Assuming that $χ'(0)$ has no significant dependence on quark masses, the mass of $η'$ in the chiral limit is found to be $\approx$723 MeV. The same calculation also yields for the singlet pseudoscalar decay constant in the chiral limit a value of $\approx 178$ MeV.

Host-Parasite Co-evolution and Optimal Mutation Rates for Semi-conservative Quasispecies

description: In this paper, we extend a model of host-parasite co-evolution to incorporate the semi-conservative nature of DNA replication for both the host and the parasite. We find that the optimal mutation rate for the semi-conservative and conservative hosts converge for realistic genome lengths, thus maintaining the admirable agreement between theory and experiment found previously for the conservative model and justifying the conservative approximation in some cases. We demonstrate that, while the optimal mutation rate for a conservative and semi-conservative parasite interacting with a given immune system is similar to that of a conservative parasite, the properties away from this optimum differ significantly. We suspect that this difference, coupled with the requirement that a parasite optimize survival in a range of viable hosts, may help explain why semi-conservative viruses are known to have significantly lower mutation rates than their conservative counterparts.

description: A dynamic model of a society is studied where each person is an uncorrelated and non-interacting random walker. A dynamical random graph represents the acquaintance network of the society whose nodes are the individuals and links are the pairs of mutual friendships. This network exhibits a novel percolation like phase transition in all dimensions. On introducing simultaneous death and birth rates in the population we show that the friendship network shows the six degrees of separation for ever after where the precise value of the network diameter depends on the death/birth rate. A SIS type model of disease spreading shows that this society remains always healthy if the population density is less than certain threshold value.

Os resultados indicaram cicios bem definidos para o milho e o arroz. Quanto ao feijão, devido ao seu comportamento irregular no mercado, não apresentou qualquer padrão cíclico. Concluiu-se que a adoção de uma política que vise a melhores níveis de preço aos produtos acarretará maior custo social no caso do milho, pois este produto apresentou o menor coeficiente de flexibilidade de preço. Para o feijão, não foi possível medir este efeito, pois o comportamento do produto não foi descrito significativamente pelo método de Análise Harmônica.

description: We have studied the electronic structure of epitaxially grown thin films of La$_{1-x}$Sr$_x$FeO$_3$ by {\it in-situ} photoemission spectroscopy (PES) and x-ray absorption spectroscopy (XAS) measurements. The Fe 2$p$ and valence-band PES spectra and the O $1s$ XAS spectra of LaFeO$_3$ have been successfully reproduced by configuration-interaction cluster-model calculation and, except for the satellite structure, by band-structure calculation.From the shift of the binding energies of core levels, the chemical potential was found to be shifted downward as $x$ was increased. Among the three peaks in the valence-band spectra of La$_{1-x}$Sr$_x$FeO$_3$, the peak nearest to the Fermi level ($E_F$), due to the ``$e_{g}$ band'', was found to move toward $E_F$ and became weaker as $x$ was increased, whereas the intensity of the peak just above $E_F$ in the O $1s$ XAS spectra increased with $x$. The gap or pseudogap at $E_F$ was seen for all values of $x$. These results indicate that changes in the spectral line shape around $E_F$ are dominated by spectral weight transfer from below to above $E_F$ across the gap and are therefore highly non-rigid-band-like.

Os resultados obtidos mostram que o nível de vida dos agricultores foi fortemente influenciado pela cultura da cana-de-açúcar. Dentre todos os agricultores, aqueles que se dedicam ao plantio de cana-de-açúcar apresentam nível de vida mais elevado, mesmo quando controlados os fatores área da unidade produtiva e posse da terra. Da mesma forma, a posse da terra e a área da unidade de produção agrícola não definem o nível de tecnologia empregado pelos agricultores, porque, quando controlada a influência da cultura canavieira, não se mostraram associadas ao nível de tecnologia. Desta forma, a presença da cultura canavieira modifica as diferenças esperadas e devidas às condições de posse da terra, e da área da unidade produtiva.

The experiment setup was optimized to evaluate the technique for determining the integrated beam-target luminosity in neutron-neutron coincidence cross-section measurements in neutron-deuteron breakup. The measurements were carried out with a systematic uncertainty of $\pm 5.6 \%$. Our data are in agreement with theoretical calculations performed using the CD-Bonn nucleon-nucleon potential in the Faddeev formalism. The measured integrated cross section over the quasifree peak is $20.5 \pm 0.5 \text{(stat)} \pm 1.1 \text{(sys)}$ mb/sr$^2$ in comparison with the theory prediction of 20.1 mb/sr$^{2}$. These results validate our technique for determining the beam-target luminosity in neutron-deuteron breakup measurements.

description: A análise da distribuição dos imóveis rurais conforme sua área, de acordo com o cadastro do INCRA, revela o elevado grau de concentração da propriedade da terra no Brasil. Entretanto, a área de um imóvel rural é uma medida apenas aproximada de seu valor econômico. Áreas iguais podem ter valores bastante diferentes, em função de sua localização e fertilidade do solo. A desigualdade entre imóveis rurais também pode ser medida considerando-se o valor da produção e o número de módulos por imóvel. Embora se reconheça a precariedade dos dados utilizados (especialmente os referentes ao número de maduros dos imóveis rurais), procura-se estabelecer a importância relativa das variações da qualidade econômica da terra na desigualdade entre imóveis rurais. O trabalho mostra que a razão fundamental para a grande desigualdade na distribuição dos imóveis rurais conforme sua área é a desigualdade econômica.
title: Measurement of Creep Deformation in Weldments

description: This PhD project has developed a new high temperature strain measurement system using Digital Image Correlation (DIC) in order to investigate spatially varying and time dependent deformation during high temperature creep tests of engineering materials. Several challenges associated with measuring creep deformation at elevated temperature have been overcome including the choice of specimen design, specimen oxidation, furnace temperature uniformity, image distortion caused by thermal currents and sufficient illumination. It is demonstrated that the system created can produce reliable measurement data over a period of several months with a spatial resolution of 0.6 mm for temperatures up to 650°C, but in principle higher resolution and temperatures should be achievable. The research aim of this project, funded by EDF Energy (formerly British Energy), was to attempt to measure spatially varying creep deformation properties across thick and thin section weldments that operate at high temperatures in UK advanced gas cooled reactor power plant (AGR). The new measurement system is applied to examine the creep behaviour of a thick section multi-pass welded joint made from Type 316H austenitic stainless steel which was supplied by EDF Energy. Specifically the local creep deformation properties across the weldment in the parent material, heat affected zone (HAZ) and multipass weld layers are investigated in medium term creep tests (>2300 hours). This is achieved by cutting samples from three different locations of the thick section joint, that is from top, middle and bottom positions, and subjecting them to tensile and creep testing at a temperature of 545°C. Spatially resolved stress-strain (tensile) and strain-time (creep) results were obtained transversely across the whole section of the multi-pass weldment and across the thickness direction. The DIC in-situ measurements also provided strain information in the transverse to loading direction from which the reduction of area of the specimen and true stress and strain distribution were calculated. The weld metal showed faster creep rates than HAZ and parent materials and this is attributed to the observed introduction of substantial plastic strain in the parent material on initial loading. Locally the creep strain distribution in the weld metal appears to correlate with individual weld passes. The full-field measurement results allowed the development of creep deformation leading to ultimate rupture to be observed. The high temperature tensile and creep results presented in this thesis demonstrate the capability of the new DIC based system created for full field measurements of displacement and strain at high temperature during creep tests enduring several thousand hours. The system opens a new horizon for studying deformation and rupture behaviour of complex structures at elevated temperature.
title: A Discursive Investigation of Leading in Organisational Conversations
Creators: name: Darch, Helen Mary
Publisher: name: The Open University

description: This exploratory study aimed first to investigate interactions in conversations to see how moments of leadership might arise. This responded to a call to conduct empirical research in an underexplored area of leadership in relational processes where the process rather than the person is the focus of study. It adopted a methodology of organisational discourse analysis, using conversation analysis as a method which has been rarely used to study relational processes to date. A secondary aim was to explore methodologies and methods that might be used in the PhD phase to study relational leadership where this is founded in processes. The study addressed the question: how do interactions in conversation create moments where one person leads, or not, others. Preliminary results from a study of secondary video data suggest leadership in relational processes, specifically relational dialogue, can be observed in interactions but may be fleeting and incomplete. An additional investigation looked at leadership in three outcomes of direction, alignment and commitment and found these arose in conversations but not necessarily simultaneously. These findings contribute to our understanding of how leadership arises in relational processes by exploring these processes in naturally occurring conversations. Theoretically this study complements the existing literature with a social constructionist perspective and using a method little used to study leadership in relation. The method and methodology adopted encompassed reflexivity and the role of judgement in how data is handled and interpreted. The trustworthiness, methodological issues, limitations and implications for future research are also discussed.

description: A generalized two-center cluster model (GTCM), including various partitions of the valence nucleons around two alpha-cores, is proposed for studies on the exotic cluster structures of Be isotopes. This model is applied to the 10Be = alpha + alpha + n + n system and the adiabatic energy surfaces for alpha-alpha distances are calculated. It is found that this model naturally describes the formation of the molecular orbitals as well as that of asymptotic cluster states dependeing on their relative distance. In the negative-parity state, a new type of the alpha + 6He cluster structure is also predicted.

description: O Estado do Rio de Janeiro é o quarto produtor nacional de açúcar. Pela importância sócio-econômica de que se reveste a cultura da cana-de-açúcar para a região, a análise das relações produtividade-preço, com base na teoria da oferta, é de grande significado para a orientação de políticas a serem adotadas no setor. O principal objetivo deste estudo é estimar as elasticidades da produtividade em relação a mudanças nos preços em cana-de-açúcar para o Estado do Rio de Janeiro, com dados temporais de 1948/75. A técnica econométrica utilizada foi dos mínimos quadrados ordinários, aplicando-se o modelo, nerloviano de retardamento distribuído. Os resultados demonstraram uma racionalidade no comportamento do produtor face a variações nos preços do produto. A sensibilidade dos produtores face a variações de preços é maior a longo prazo do que a curto prazo, conforme mostram as elasticidades-preço.

description: Map makers have long searched for a way to construct cartograms -- maps in which the sizes of geographic regions such as countries or provinces appear in proportion to their population or some other analogous property. Such maps are invaluable for the representation of census results, election returns, disease incidence, and many other kinds of human data. Unfortunately, in order to scale regions and still have them fit together, one is normally forced to distort the regions' shapes, potentially resulting in maps that are difficult to read. Many methods for making cartograms have been proposed, some of them extremely complex, but all suffer either from this lack of readability or from other pathologies, like overlapping regions or strong dependence on the choice of coordinate axes. Here we present a new technique based on ideas borrowed from elementary physics that suffers none of these drawbacks. Our method is conceptually simple and produces useful, elegant, and easily readable maps. We illustrate the method with applications to the results of the 2000 US presidential election, lung cancer cases in the State of New York, and the geographical distribution of stories appearing in the news.

description: Este trabalho analisa a alocação e produtividade dos recursos utilizados na produção pecuária nas Divisões Regionais Agrícolas de Araçatuba, Bauru, São José do Rio Preto e Presidente Prudente, no Estado de São Paulo. A metodologia utilizada é constituída pela estimativa de funções de produção e pela decomposição da produtividade total entre os fatores de produção considerados. Entre os resultados obtidos, tem-se que todas as funções estimadas apresentaram bom ajustamento. O mesmo ocorreu com todos os fatores, com exceção de trabalho, que foram significantes ao nível de, 5% de probabilidade. As funções estimadas para a atividade pecuária indicaram retornos constantes à escala, enquanto que nas estimadas por DIRA os retornos à escala foram levemente crescentes. Enquanto que as funções estimadas por atividades eram estatisticamente diferentes, as estimadas por região apresentaram resultados díspares. Os fatores que apresentaram maiores produtividades foram terra e capital fixo. Na análise inter-regional, o fator terra apresentou maior produtividade na DIRA de Presidente Prudente e menor na DIRA de Bauru. O fator trabalho apresentou maior valor do produto marginal na DIRA de Bauru. No caso dos fatores capital fixo e operacional, maiores VPMG foram encontrados nas DIRAs de São José do Rio Preto e Araçatuba. As diferenças regionais encontradas sugerem ajustamentos na política agrícola relativa ao setor pecuário, ao nível das DIRAs, a fim de melhorar a eficiência na alocação de recursos.

description: We propose a learning-based scheme to investigate the dynamic multi-channel access (DMCA) problem in the fifth generation (5G) and beyond networks with fast time-varying channels wherein the channel parameters are unknown. The proposed learning-based scheme can maintain near-optimal performance for a long time, even in the sharp changing channels. This scheme greatly reduces processing delay, and effectively alleviates the error due to decision lag, which is cased by the non-immediacy of the information acquisition and processing. We first propose a psychology-based personalized quality of service model after introducing the network model with unknown channel parameters and the streaming model. Then, two access criteria are presented for the living streaming model and the buffered streaming model. Their corresponding optimization problems are also formulated. The optimization problems are solved by learning-based DMCA scheme, which combines the recurrent neural network with deep reinforcement learning. In the learning-based DMCA scheme, the agent mainly invokes the proposed prediction-based deep deterministic policy gradient algorithm as the learning algorithm. As a novel technical paradigm, our scheme has strong universality, since it can be easily extended to solve other problems in wireless communications. The real channel data-based simulation results validate that the performance of the learning-based scheme approaches that derived from the exhaustive search when making a decision at each time-slot, and is superior to the exhaustive search method when making a decision at every few time-slots.

description: Topologically protected waves in the linearly polarized Maxwell's equations with gyrotropic, magneto-optic media were studied a decade ago both computationally and experimentally. This paper develops a robust tight-binding model for this system that makes careful use of Wannier function representations. The model provides very good approximations to the underlying band structure. When solved on a semi-infinite strip, it produces exponentially localized edge modes whose corresponding eigenvalues span the frequency band gaps. A set of coupled differential equations are derived which allows one to find how the electromagnetic field propagates unidirectionally, without backscatter from defects. Furthermore, the discrete model predicts topologically protected edge modes with nontrivial Chern number which are consistent with direct simulation.
