description: For an ideal D-dimensional Fermi gas under generic external confinement we derive the correcting coefficient $(D-2)/3D$ of the von Weizsacker term in the kinetic energy density. To obtain this coefficient we use the Kirzhnits semiclassical expansion of the number operator up to the second order in the Planck constant $\hbar$. Within this simple and direct approach we determine the differential equation of the density profile and the density functional of the Fermi gas. In the case D=2 we find that the Kirzhnits gradient corrections vanish to all order in $\hbar$.

description: Previous observations with the Rossi X-ray Timing Explorer (RXTE) have suggested that the power spectral density (PSD) of NGC 3783 flattens to a slope near zero at low frequencies, in a similar manner to that of Galactic black hole X-ray binary systems (GBHs) in the `hard' state. The low radio flux emitted by this object, however, is inconsistent with a hard state interpretation. The accretion rate of NGC 3783 (~7% of the Eddington rate) is similar to that of other AGN with `soft' state PSDs and higher than that at which the GBH Cyg X-1, with which AGN are often compared, changes between `hard' and `soft' states (~2% of the Eddington rate). If NGC 3783 really does have a `hard' state PSD, it would be quite unusual and would indicate that AGN and GBHs are not quite as similar as we currently believe. Here we present an improved X-ray PSD of NGC 3783, spanning from ~10^{-8} to ~10^{-3} Hz, based on considerably extended (5.5 years) RXTE observations combined with two orbits of continuous observation by XMM-Newton. We show that this PSD is, in fact, well fitted by a `soft' state model which has only one break, at high frequencies. Although a `hard' state model can also fit the data, the improvement in fit by adding a second break at low frequency is not significant. Thus NGC 3783 is not unusual. These results leave Arakelian 564 as the only AGN which shows a second break at low frequencies, although in that case the very high accretion rate implies a `very high', rather than `hard' state PSD. The break frequency found in NGC 3783 is consistent with the expectation based on comparisons with other AGN and GBHs, given its black hole mass and accretion rate.

description: The ghost and gluon propagator and the ghost-gluon and three-gluon vertex of two-dimensional SU(2) Yang-Mills theory in (minimal) Landau gauge are studied using lattice gauge theory. It is found that the results are qualitatively similar to the ones in three and four dimensions. The propagators and the Faddeev-Popov operator behave as expected from the Gribov-Zwanziger scenario. In addition, finite volume effects affecting these Green's functions are investigated systematically. The critical infrared exponents of the propagators, as proposed in calculations using stochastic quantization and Dyson-Schwinger equations, are confirmed quantitatively. For this purpose lattices of volume up to (42.7 fm)^2 have been used.

description: Employing the nonequilibrium Green's function method, we develop a fully quantum mechanical model to study the coupled electron-phonon transport in one-dimensional atomic junctions in the presence of a weak electron-phonon interaction. This model enables us to study the electronic and phononic transport on an equal footing. We derive the electrical and energy currents of the coupled electron-phonon system and the energy exchange between them. As an application, we study the heat dissipation in current carrying atomic junctions within the self-consistent Born approximation, which guarantees energy current conservation. We find that the inclusion of phonon transport is important in determining the heat dissipation and temperature change of the atomic junctions.

description: In this paper, we derive an explicit formula for constructing the confidence interval of binomial parameter with guaranteed coverage probability. The formula overcomes the limitation of normal approximation which is asymptotic in nature and thus inevitably introduce unknown errors in applications. Moreover, the formula is very tight in comparison with classic Clopper-Pearson's approach from the perspective of interval width. Based on the rigorous formula, we also obtain approximate formulas with excellent performance of coverage probability.

description: We report observation of spin-orbit Berry's phase in the Aharonov-Bohm (AB) type oscillation of weak field magnetoresistance in an anti-dot lattice (ADL) of a two-dimensional hole system. An AB-type oscillation is superposed on the commensurability peak, and the main peak in the Fourier transform is clearly split up due to variation in Berry's phase originating from the spin-orbit interaction. A simulation considering Berry's phase and the phase arising from the spin-orbit shift in the momentum space shows qualitative agreement with the experiment.

Towards building the OP-Mapped WENO schemes: A general methodology
Creators: name: Li, Ruo
name: Zhong, Wei
Publisher: name: arXiv
Year: 2021
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: A serious and ubiquitous issue in existing mapped WENO schemes is that most of them can hardly preserve high resolutions and in the meantime prevent spurious oscillations on solving hyperbolic conservation laws with long output times. Our goal in this article is to address this widely concerned problem [3, 4, 15, 29, 16, 18]. In our previous work [18], the order-preserving (OP) criterion was originally introduced and carefully used to devise a new mapped WENO scheme that performs satisfactorily in long-run simulations, and hence it was indicated that the OP criterion plays a critical role in the maintenance of low-dissipation and robustness for the mapped WENO schemes. Thus, in our present work, we firstly define the family of the mapped WENO schemes, whose mappings meet the OP criterion, as OP-Mapped WENO. Next, we attentively take a closer look at the mappings of various existing mapped WENO schemes and devise a general formula for them. It helps us to extend the OP criterion into the design of the improved mappings. Then, we propose the generalized implementation of obtaining a group of OP-Mapped WENO schemes, named MOP-WENO-X as they are developed from the existing mapped WENO-X schemes, where the notation "X" is used to identify the version of the existing mapped WENO scheme. Finally, extensive numerical experiments and comparisons with competing schemes are conducted to demonstrate the enhanced performances of the MOP-WENO-X schemes.

description: We use mirror symmetry to determine and sum up a class of membrane instanton corrections to the hypermultiplet moduli space metric arising in Calabi-Yau threefold compactifications of type IIA strings. These corrections are mirror to the D1 and D(-1)-brane instantons on the IIB side and are given explicitly in terms of a single function in projective superspace. The corresponding four-dimensional effective action is completely fixed by the Euler number and the genus zero Gopakumar-Vafa invariants of the mirror Calabi-Yau.

description: When light is passing through a rotating medium the optical polarisation is rotated. Recently it has been reasoned that this rotation applies also to the transmitted image (Padgett et al. 2006). We examine these two phenomena by extending an analysis of Player (1976) to general electromagnetic fields. We find that in this more general case the wave equation inside the rotating medium has to be amended by a term which is connected to the orbital angular momentum of the light. We show that optical spin and orbital angular momentum account respectively for the rotation of the polarisation and the rotation of the transmitted image.

description: The two-dimensional kagome lattice hosts Dirac fermions at its Brillouin zone corners K and K', analogous to the honeycomb lattice. In the density functional theory electronic structure of ferromagnetic kagome metal Fe$_3$Sn$_2$, without spin-orbit coupling we identify two energetically split helical nodal lines winding along $z$ in the vicinity of K and K' resulting from the trigonal stacking of the kagome layers. We find that hopping across A-A stacking introduces a layer splitting in energy while that across A-B stacking controls the momentum space amplitude of the helical nodal lines. The effect of spin-orbit coupling is found to resemble that of a Kane-Mele term, where the nodal lines can either be fully gapped to quasi-two-dimensional massive Dirac fermions, or remain gapless at discrete Weyl points depending on the ferromagnetic moment orientation. Aside from numerically establishing Fe$_3$Sn$_2$ as a model Dirac kagome metal, our results provide insights into materials design of topological phases from the lattice point of view, where paradigmatic low dimensional lattice models often find realizations in crystalline materials with three-dimensional stacking.

A Gravitational Wave Background from Reheating after Hybrid Inflation

description: The reheating of the universe after hybrid inflation proceeds through the nucleation and subsequent collision of large concentrations of energy density in the form of bubble-like structures moving at relativistic speeds. This generates a significant fraction of energy in the form of a stochastic background of gravitational waves, whose time evolution is determined by the successive stages of reheating: First, tachyonic preheating makes the amplitude of gravity waves grow exponentially fast. Second, bubble collisions add a new burst of gravitational radiation. Third, turbulent motions finally sets the end of gravitational waves production. From then on, these waves propagate unimpeded to us. We find that the fraction of energy density today in these primordial gravitational waves could be significant for GUT-scale models of inflation, although well beyond the frequency range sensitivity of gravitational wave observatories like LIGO, LISA or BBO. However, low-scale models could still produce a detectable signal at frequencies accessible to BBO or DECIGO. For comparison, we have also computed the analogous gravitational wave background from some chaotic inflation models and obtained results similar to those found by other groups. The discovery of such a background would open a new observational window into the very early universe, where the details of the process of reheating, i.e. the Big Bang, could be explored. Moreover, it could also serve in the future as a new experimental tool for testing the Inflationary Paradigm.

description: We show that it can be considered some of Bach pitches series as a stochastic process with scaling behavior. Using multifractal deterend fluctuation analysis (MF-DFA) method, frequency series of Bach pitches have been analyzed. In this view we find same second moment exponents (after double profiling) in ranges (1.7-1.8) in his works. Comparing MF-DFA results of original series to those for shuffled and surrogate series we can distinguish multifractality due to long-range correlations and a broad probability density function. Finally we determine the scaling exponents and singularity spectrum. We conclude fat tail has more effect in its multifractality nature than long-range correlations.

description: The aim of the present work is to show how, using the differential calculus associated to Dirichlet forms, it is possible to construct Fredholm modules on post critically finite fractals by regular harmonic structures. The modules are d-summable, the summability exponent d coinciding with the spectral dimension of the generalized laplacian operator associated with the regular harmonic structures. The characteristic tools of the noncommutative infinitesimal calculus allow to define a d-energy functional which is shown to be a self-similar conformal invariant.

Three piano sonatas by Friedrich Kuhlau
Creators: name: Dawe, Edmund Noel
Publisher: name: University of British Columbia
Year: 2010

description: Friedrich Kuhlau (1786-1832) ranks as a minor master of the early nineteenth century. As a composer of keyboard music he is perhaps best known for his sets of sonatinas, but the twenty-two sonatas he composed from 1809 to 1831 form a significant part of his extensive output. This study examines three of his sonatas -- Op. 4, Op. 46 No. 2 and Op. 127 -- and places them in historical context through a discussion of the importance of this genre in the repertoire of that era. A survey of contemporary keyboard performance practices is also included, as well as an introductory biographical sketch. Kuhlau's style is undeniably conservative, with phrases of regular and predictable length in evidence throughout, and his music is often derivative of that of earlier composers from C.P.E. Bach through Beethoven. However, his works also reflect numerous traits of early Romanticism. They are melodically rich, widely spaced sonorities are frequently employed, and his textures range from delicate nuances to thickly scored passages. From a purely pianistic point of view, he displays a fondness for scalewise and arpeggiated passages so often used to excess by lesser composers of his era, but he also clearly demonstrates that he was aware of more innovative approaches to keyboard writing. Throughout history, countless minor composers such as Kuhlau were highly respected during their lifetimes; nevertheless, most of their compositions, including those under consideration here, have not survived on the concert stage. Consequently, there exists a vast body of literature of which little or nothing is known. It is both necessary and useful to study such works in order to gain a more complete understanding of music of their period. Moreover, a closer examination of them might well lead to a reassessment of their worth, which in turn may encourage more frequent performances.

description: Este artigo apresenta os resultados de um estudo descritivo e quantitativo visou analisar as pesquisas publicadas sobre o custeio baseado em atividades (ABC) entre 2001 e 2010 nos principais periódicos de Contabilidade do país. A análise foi realizada por meio da estatística descritiva, da análise bibliométrica e da análise sociométrica. Não se verificou uma tendência de aumento ou redução das publicações sobre ABC no período. Todavia, identificou-se uma predominância dos estudos empíricos sobre os teóricos. Observou-se, ainda, uma forte concentração da produção científica sobre ABC em três autores. Ademais, verificaram-se resultados distintos do previsto pela Lei de Lotka, já que um grande número de autores publicou apenas um artigo no período. Isso parece demonstrar que os autores não estavam relacionados a linhas de pesquisas consolidadas sobre o tema. Na análise sociométrica, observou-se que as redes sociais estabelecidas entre os autores são normalmente dispersas e não possuem muitos laços entre si.

description: The generator coordinate method begins with the variational construction of a set of non-orthogonal mean-field states that span a subspace of the full many-body Hilbert space. These states are then often projected onto states with good quantum numbers to restore symmetries, leading to a set with members that can be similar to one another, and it is sometimes possible to reduce this set without greatly affecting results. Here we propose a greedy algorithm that we call the energy-transition-orthogonality procedure (ENTROP) to select subsets of important states. As applied here, the approach selects on the basis of diagonal energy, orthogonality, and contribution to the matrix element that governs neutrinoless double-$β$ decay. We present both shell-model and preliminary ab initio calculations of this matrix element for the decay of $^{76}$Ge, with quadrupole deformation parameters and the isoscalar pairing strength as generator coordinates. ENTROP converges quickly, reducing significantly the number of basis states needed for an accurate calculation.

description: As percepções iniciais e finais dos docentes sobre as disciplinas que ministram podem influenciar no desempenho acadêmico dos discentes. Com foco descritivo e abordagem quantitativa, essa pesquisa tem como objetivo verificar se a percepção do professor em relação às disciplinas iniciais de contabilidade está relacionada com o desempenho dos alunos dos cursos de Ciências Contábeis, Administração, Economia e Gestão Da Informação de uma universidade mineira. O levantamento de dados foi realizado por meio da aplicação de dois questionários adaptados de Geiger e Ogilby (2000) para uma amostra de oito professores que ministraram as disciplinas iniciais de contabilidade no primeiro semestre de 2014. Os resultados da pesquisa sugerem que as percepções dos docentes acerca das disciplinas iniciais de contabilidade influenciam no desempenho do aluno. Especificamente, os discentes das turmas dos professores que apresentaram percepções mais positivas, principalmente no quesito apreciação e motivação, tiveram desempenho final mais satisfatório.

description: We address the issue of the neutrino masses and mixing in TeV scale $B-L$ extension of the Standard Model. We show that if Dirac neutrino masses are of order $10^{-4}$ Gev, then the measured neutrino masses are correctly obtained. We propose a mass relation between quarks and leptons that may account for such small Dirac neutrino masses. We analyze the leptogenesis in this type of models and provide analytical expressions for the new contributions due to the predicted extra Higgs and extra neutral gauge boson. We find that thermal leptogenesis, with a resonant enhancement due to nearly degenerate right-handed neutrinos, can yield sufficient baryon asymmetry. Finally, we comment on a possible scheme for non-thermal leptogenesis, which is due to the decay of extra Higgs into right-handed neutrino.

description: O objetivo do estudo foi analisar as informações relativas aos contratos de construção civil previstas no CPC 17, evidenciadas por empresas listadas na BM&FBovespa. A pesquisa caracteriza-se como um estudo descritivo, documental e de caráter quantitativo, em uma amostra de 19 empresas do ramo da construção civil no período de 2012 a 2014. Os resultados da pesquisa indicam que o método utilizado pelas empresas investigadas é o método da percentagem completada, reconhecendo as receitas e custos de acordo com o estágio de execução da obra. Todas as empresas divulgaram valores de passivos contingentes, mas apenas uma relatou passivos contingentes ambientais. As empresas brasileiras investigadas ainda não atendem por completo as exigências do checklist analisado, sendo que a mediana da divulgação foi equivalente a 60%. Os resultados de modo geral, indicam que a adequação às exigências relativas aos contratos de construção do CPC 17 ocorre apenas de forma parcial.

description: This study explores the impact of technological developments on Generation Z, especially the security of transactions using electronic payment methods. By focusing on understanding attitudes, behavior, and challenges related to technology, this research aims to identify the factors that influence Generation Z's behavior toward the security of electronic payment transactions. The data collection process was carried out from April 19, 2024, to April 26, 2024, in this research by asking questions via Google Forms. This method was chosen to explore various factors that influence the use of e wallets in Generation Z. A total of 194 responses were collected from 200 participants who have used or are currently using e wallets. Of these respondents, 121 women (62.4%) reported using e-wallets, while 73 men (37.6%) reported using e-wallets. The methodology used in this research uses Partial Least Squares Structural Equation Modeling (PLS-SEM) and SMART-PLS 3 software. The results validate 22 of the 28 indicators considered. This validation is proven through observations of external loads which are in the range of 0.7 to above 0.9. However, it should be noted that indicators such as ATU3, ATU5, PEU2, PEU5, SE5, and UB4 show external loading outside the range mentioned above, thus making them invalid. This study emphasizes the statistical significance of these factors, providing insight into their role in shaping Generation Z's attitudes toward electronic payment adoption.

description: We use the recipe of arXiv:1003.2974 to find half-BPS near-horizon geometries in the t$^3$ model of $N=2$, $D=4$ gauged supergravity, and explicitely construct some new examples. Among these are black holes with noncompact horizons, but also with spherical horizons that have conical singularities (spikes) at one of the two poles. A particular family of them is extended to the full black hole geometry. Applying a double-Wick rotation to the near-horizon region, we obtain solutions with NUT charge that asymptote to curved domain walls with AdS$_3$ world volume. These new solutions may provide interesting testgrounds to address fundamental questions related to quantum gravity and holography.

The First Law for Boosted Kaluza-Klein Black Holes

description: We study the thermodynamics of Kaluza-Klein black holes with momentum along the compact dimension, but vanishing angular momentum. These black holes are stationary, but non-rotating. We derive the first law for these spacetimes and find that the parameter conjugate to variations in the length of the compact direction is an effective tension, which generally differs from the ADM tension. For the boosted black string, this effective tension is always positive, while the ADM tension is negative for large boost parameter. We also derive two Smarr formulas, one that follows from time translation invariance, and a second one that holds only in the case of exact translation symmetry in the compact dimension. Finally, we show that the `tension first law' derived by Traschen and Fox in the static case has the form of a thermodynamic Gibbs-Duhem relation and give its extension in the stationary, non-rotating case.

description: Essa pesquisa tem como objetivo analisar o nível de cumprimento das companhias abertas do setor elétrico dos requisitos de divulgação do Pronunciamento Técnico CPC 27 no período de 2010 a 2013, assim como seus determinantes. Foram analisadas as Notas Explicativas das demonstrações contábeis de 30 empresas de capital aberto do setor elétrico de 2010 a 2013e foi calculado o índice de não divulgação (IND). Em seguida, foi montada uma regressão com variáveis que pudessem explicar o nível de divulgação das companhias. Os resultados demonstram que o IND médio para o setor elétrico corresponde a 52,69% no período analisado. Uma possível explicação para os resultados é o nível detalhamento das informações sobre ativo imobilizado, que pode ser um fator que dificulta a implementação dessa norma. Outra hipótese refere-se à insuficiente fiscalização exercida pelos órgãos reguladores. Foi constatado que as variáveis tamanho, grau de imobilização e governança corporativa são estatisticamente significativas.

Cloning and characterization of the oprF gene for protein F from Pseudomonas aeruginosa
Creators: name: Woodruff, Wendy Anne
Publisher: name: University of British Columbia
Year: 2010

description: The oprF gene encoding porin protein F from Pseudomonas aeruginosa was cloned onto a cosmid vector into Escherichia coli. Protein F was expressed in large amounts in E. coli and retained its heat- and reduction-modifiable and immunological characteristics. The cloned oprF gene product was purified from E. coli and characterized with respect to pore-forming ability in black lipid bilayers. Small channels, with an average single channel conductance of approximately 0.4 nS, were observed. A similar small channel size was observed for native protein F. The oprF sequences were used as a DNA-DNA hybridization probe with chromosomal DNA from the 17 IATS (International Antigen Typing Scheme) strains of P. aeruginosa, 52 clinical isolates and the non-aeruginosa Pseudomonads. Conservation of oprF sequences was observed among all the P. aeruginosa strains and to a lesser extent among the non-aeruginosa strains of the P. fluorescens rRNA homology group. Insertion mutations in the oprF gene were created in vivo by Tn1mutagenesis of the cloned gene in E. coli and in vitro by insertion of the streptomycin-encoding Ω fragment into the cloned gene, followed by transfer of the mutated protein F gene back into P. aeruginosa and homologous recombination with the chromosome. The oprF mutants were characterized by gel electrophoresis and immunoblotting, and it was shown that the mutants had lost protein F. The P. aeruginosa oprF mutants were characterized with respect to growth rates, antibiotic permeability and cell surface hydrophobicity. The results of these studies indicated that major alterations in the cell surface had occurred and that the cells were unable to grow in a non-defined liquid medium without added electrolytes. Marginal differences were observed in MICs (minimum inhibitory concentrations) of hydrophilic antibiotics for the oprF mutants compared with their protein F-sufficient parents. The putative roles of protein F in antibiotic permeability and general outer membrane permeability are discussed. Evidence for extensive homologies between protein F, the OmpA protein of E. coli and PHIII of Neisseria gonorrhoeae are presented. A role for protein F in prophylactic anti-Pseudomonas therapy, as a target for vaccine development, is proposed.

description: A pesquisa tem o objetivo de avaliar a percepção sobre a informação contábil gerada pela contabilidade e recebida pelos usuários da informação contábil por meio dos estudantes concluintes dos cursos de ciências contábeis e de administração das instituições de ensino superior em Natal/RN. A literatura demonstra que a preocupação com o aspecto qualitativo da informação contábil não é recente e cresce à medida que a gama de usuários dessas informações se amplia. O processo de comunicação contábil considera a capacidade que os usuários têm para compreender e interpretar a informação de forma correta. A pesquisa realizou o levantamento de dados por meio da aplicação de questionário e os resultados mostram que o processo de comunicação não ocorre de maneira eficiente e tampouco eficaz, tal como requer a teoria contábil e preconiza a teoria da comunicação, revelando uma necessidade de melhoria no processo de ensino-aprendizagem nas áreas relacionadas.

description: We investigate up to which order quantum effects can be neglected in calculating cosmological correlation functions after horizon exit. As a toy model, we study $ϕ^3$ theory on a de Sitter background for a massless minimally coupled scalar field $ϕ$. We find that for tree level and one loop contributions in the quantum theory, a good classical approximation can be constructed, but for higher loop corrections this is in general not expected to be possible. The reason is that loop corrections get non-negligible contributions from loop momenta with magnitude up to the Hubble scale H, at which scale classical physics is not expected to be a good approximation to the quantum theory. An explicit calculation of the one loop correction to the two point function, supports the argument that contributions from loop momenta of scale $H$ are not negligible. Generalization of the arguments for the toy model to derivative interactions and the curvature perturbation leads to the conclusion that the leading orders of non-Gaussian effects generated after horizon exit, can be approximated quite well by classical methods. Furthermore we compare with a theorem by Weinberg. We find that growing loop corrections after horizon exit are not excluded, even in single field inflation.
