description: The kaon electromagnetic (e.m.) form factor is reviewed considering a light-front constituent quark model. In this approach, it is discussed the relevance of the quark-antiquark pair terms for the full covariance of the e.m. current. It is also verified, by considering a QCD dynamical model, that a good agreement with experimental data can be obtained for the kaon weak decay constant once a probability of about 80% of the valence component is taken into account.

description: Members of the Ciliate Genomics Consortium (CGG) formed a fall working group to brainstorm how to convert existing Course-based Undergraduate Research (CURE) curriculum modules, which have been shared privately, into open education resources (OER) and populate these as resources on a CGC QUBEShub. After our initial meeting, the group decided that we should consider that motivation for teaching with CUREs before making the OERs so that the final resources would be ready for adoption by other. Methods: the group meetings consisted of a chapter by chapter journal club of the Dolan and Weaver (2021) text "A Guide to Course-based Undergraduate Research" (Macmillan). Through this study, we developed a draft of questions that instructors can use to consider whether they and their students would benefit from teaching using a CURE. We plan to develop a decision tree to use with these questions. We also started to develop additional resources that will help faculty align the research goal of a CURE with student learning goals and how assignments can assess whether research and/or learning goals are achieved. This work will provide complementary material to the CURE curriculum we curate.

description: Desde o ano de 1995, com o lançamento do Plano Diretor de Reforma do Aparelho do Estado, o Governo Federal vem propondo a difusão de doutrinas de gestão pública, voltadas para os resultados. Nesse contexto, um órgão da Marinha do Brasil vem se destacando pelo êxito obtido no alcance dos objetivos estabelecidos em seu planejamento estratégico. O referido órgão, denominado CASNAV, obteve seguidas premiações, entre os anos de 2004 e 2007, no Prêmio Nacional da Gestão Pública, vinculado ao Ministério do Planejamento Orçamento e Gestão. Nesse mesmo período, observou-se que o CASNAV utilizou-se de diversos mecanismos com o propósito de criar condições favoráveis à ocorrência de comportamentos adequados por parte de seus membros, visando o alcance das metas estabelecidas. Assim, o presente estudo objetiva verificar se o investimento no capital intelectual (CI) pode ser apontado como um dos instrumentos de controle gerencial que contribuíram nesse processo. Para tanto, utilizou-se o estudo de caso como estratégia de pesquisa, buscando-se apresentar as características principais do sistema de controle gerencial da organização e o detalhamento da gestão do CI dentro desse sistema. Os resultados alcançados no presente trabalho sugerem que no sistema de controle gerencial existente no CASNAV há uma clara relação entre o capital intelectual, o processo de comunicação e a cultura organizacional, que contribuiu para potencializar os efeitos gerados pelo investimento em CI, no que tange à sua capacidade de influenciar o comportamento dos membros da referida organização. Em especial, a ênfase dada pela organização no desenvolvimento do seu capital humano aponta para um aumento da probabilidade de ocorrer a congruência de objetivos individuais e organizacionais, conforme o pensamento de Flamholtz (1979). Assim, foi possível chegar-se ao entendimento de que o investimento no capital intelectual, desenvolvido pelo CASNAV, pode ser apontado como um dos instrumentos de controle gerencial adotados por essa organização, à luz do que preconiza a literatura.

description: Reliable automation of the labor-intensive manual task of scoring animal sleep can facilitate the analysis of long-term sleep studies. In recent years, deep-learning-based systems, which learn optimal features from the data, increased scoring accuracies for the classical sleep stages of Wake, REM, and Non-REM. Meanwhile, it has been recognized that the statistics of transitional stages such as pre-REM, found between Non-REM and REM, may hold additional insight into the physiology of sleep and are now under vivid investigation. We propose a classification system based on a simple neural network architecture that scores the classical stages as well as pre-REM sleep in mice. When restricted to the classical stages, the optimized network showed state-of-the-art classification performance with an out-of-sample F1 score of 0.95 in male C57BL/6J mice. When unrestricted, the network showed lower F1 scores on pre-REM (0.5) compared to the classical stages. The result is comparable to previous attempts to score transitional stages in other species such as transition sleep in rats or N1 sleep in humans. Nevertheless, we observed that the sequence of predictions including pre-REM typically transitioned from Non-REM to REM reflecting sleep dynamics observed by human scorers. Our findings provide further evidence for the difficulty of scoring transitional sleep stages, likely because such stages of sleep are under-represented in typical data sets or show large inter-scorer variability. We further provide our source code and an online platform to run predictions with our trained network.

description: Com o crescente dinamismo existente no mercado, algumas empresas utilizam a responsabilidade de cuidar para que se realize não apenas os interesses dos acionistas, mas também dos demais stakeholders, como um diferencial para tentar vencer a concorrência. Neste contexto, a evidenciação deste compromisso, pode ser feita através da DVA, que ao contrário da DRE, busca evidenciar não apenas a geração de riqueza das empresas, mas a distribuição da mesma entre os agentes relacionados à sua criação. A alteração na Lei nº 6.404 de 1976 tornou a Demonstração do Valor Adicionado obrigatória para as companhias abertas. Sendo assim, o objetivo deste estudo é contribuir para a análise dos dados da DVA e, assim, verificar a capacidade de produção e distribuição de riqueza entre os stakeholders da PETROBRAS. Para tanto, foram analisadas as demonstrações desta empresa no período de 1998 a 2007. A pesquisa é de caráter exploratório, com abordagem quantitativa realizada por meio de um estudo de caso. Para contribuir com a análise da DVA foram sugeridos indicadores criados a partir do modelo da demonstração elaborado pela FIPECAFI. Por meio da análise dos dados, verificou-se que, em média no período, 93,02% da riqueza agregada total da empresa foi proveniente de sua criação e 6,98% foi recebida por transferência de terceiros e que o stakeholder que empresa destinou o maior percentual desta riqueza, 59,39%, foi o governo.

description: This article describes the theory of cosmological perturbations around a homogeneous and anisotropic universe of the Bianchi I type. Starting from a general parameterisation of the perturbed spacetime a la Bardeen, a complete set of gauge invariant variables is constructed. Three physical degrees of freedom are identified and it is shown that, in the case where matter is described by a scalar field, they generalize the Mukhanov-Sasaki variables. In order to show that they are canonical variables, the action for the cosmological perturbations at second order is derived. Two major physical imprints of the primordial anisotropy are identified: (1) a scalar-tensor ``see-saw'' mechanism arising from the fact that scalar, vector and tensor modes do not decouple and (2) an explicit dependence of the statistical properties of the density perturbations and gravity waves on the wave-vector instead of its norm. This analysis extends, but also sheds some light on, the quantization procedure that was developed under the assumption of a Friedmann-Lemaitre background spacetime, and allows to investigate the robustness of the predictions of the standard inflationary scenario with respect to the hypothesis on the symmetries of the background spacetime. These effects of a primordial anisotropy may be related to some anomalies of the cosmic microwave background anisotropies on large angular scales.

description: The optical spectra of vertically stacked MoSe$_2$/WSe$_2$ heterostructures contain additional 'interlayer' excitonic peaks that are absent in the individual monolayer materials and exhibit a significant spatial charge separation in out-of-plane direction. Extending on a previous study, we used a many-body perturbation theory approach to simulate and analyse the excitonic spectra of MoSe$_2$/WSe$_2$ heterobilayers with three stacking orders, considering both momentum-direct and momentum-indirect excitons. We find that the small oscillator strengths and corresponding optical responses of the interlayer excitons are significantly stacking-dependent and give rise to high radiative lifetimes in the range of 5-200\,ns (at T=4\,K) for the 'bright' interlayer excitons. Solving the finite-momentum Bethe-Salpeter Equation, we predict that the lowest-energy excitation should be an indirect exciton over the fundamental indirect band gap (K$\rightarrow$Q), with a binding energy of 220\,meV. However, in agreement with recent magneto-optics experiments and previous theoretical studies, our simulations of the effective excitonic Landé g-factors suggest that the low-energy momentum-indirect excitons are not experimentally observed for MoSe$_2$/WSe$_2$ heterostructures. We further reveal the existence of 'interlayer' C excitons with significant exciton binding energies and optical oscillator strengths, which are analogous to the prominent band nesting excitons in mono- and few-layer transition-metal dichalcogenides.

O objetivo deste artigo é a modelagem das atividades da Farmácia Hospitalar para o Sistema ABC. A pesquisa é de natureza qualitativa, tendo o estudo de caso, em três organizações hospitalares, como método de pesquisa. Os resultados da pesquisa identificaram e descreveram as atividades desenvolvidas na Farmácia Hospitalar de cada um dos hospitais pesquisados. Na comparação das atividades foi observado que algumas são comuns nas três organizações e outras dependem da estrutura organizacional. As principais conclusões indicam que a modelagem das atividades pode servir como parâmetro de quais atividades é realizada em um determinado setor, para fins de benchmark tanto para o sistema de custos quanto para o sistema de informações e; as atividades que foram modeladas é uma referência, não podendo ser generalizadas para todas as organizações.

description: Cold dark matter cosmogony predicts triaxial dark matter halos, whereas observations find quite round halos. This is most likely due to the condensation of baryons leading to rounder halos. We examine the halo phase space distribution basis for such shape changes. Triaxial halos are supported by box orbits, which pass arbitrarily close to the density center. The decrease in triaxiality caused by baryons is thought to be due to the scattering of these orbits. We test this hypothesis with simulations of disks grown inside triaxial halos. After the disks are grown we check whether the phase space structure has changed by evaporating the disks and comparing the initial and final states. While the halos are substantially rounder when the disk is at full mass, their final shape after the disk is evaporated is not much different from the initial. Likewise, the halo becomes (more) radially anisotropic when the disk is grown, but the final anisotropy is consistent with the initial. Only if the baryons are unreasonably compact or massive does the halo change irreversibly. We show that the character of individual orbits is not generally changed by the growing mass. Thus the central condensation of baryons does not destroy enough box orbits to cause the shape change. Rather, box orbits merely become rounder along with the global potential. However, if angular momentum is transferred to the halo, either via satellites or via bars, a large irreversible change in the halo distribution occurs. The ability of satellites to alter the phase space distribution of the halo is of particular concern to galaxy formation simulations since halo triaxiality can profoundly influence the evolution of disks.

Tichy, B. Bruegmann, M. Campanelli, and P. Diener, Phys. Rev. D 67, 064008 (2003)], explicitly calculating the remaining integral terms. These terms improve accuracy in the far zone and, for the first time, include realistic gravitational waves in the initial data. We investigate the behavior of these data both at the center of mass and in the far zone, demonstrating agreement of the transverse-traceless parts of the new metric with quadrupole-approximation waveforms. These data can be used for numerical evolutions, enabling a direct connection between the merger waveforms and the post-Newtonian inspiral waveforms.

description: We introduce the MINERvA Analysis Toolkit (MAT), a utility for centralizing the handling of systematic uncertainties in HEP analyses. The fundamental utilities of the toolkit are the MnvHnD, a powerful histogram container class, and the systematic Universe classes, which provide a modular implementation of the many universe error analysis approach. These products can be used stand-alone or as part of a complete error analysis prescription. They support the propagation of systematic uncertainty through all stages of analysis, and provide flexibility for an arbitrary level of user customization. This extensible solution to error analysis enables the standardization of systematic uncertainty definitions across an experiment and a transparent user interface to lower the barrier to entry for new analyzers.

description: This short article reviews the recent evolution of the discipline of labour history in England from institutional history towards an expanded agenda as the social history of the working class - organised and unorganised. The key role of individual scholars and organisations in this professionalisation is noted and the main labour history research libraries and archives identified. The expansion and historiography of new areas of research - women, the unskilled, relations between the working class and labour politics, the milieux and politics of the workplace, labour management and the convergence of business and labour history - are discussed, together with the weaknesses in the discipline and the erosion in funding for labour history which has characterised the 1980s.

Dramatic Variability of X-ray Absorption Lines in the Black Hole Candidate Cygnus X-1

description: We report results from a 30 ks observation of Cygnus X-1 with the High Energy Transmission Grating Spectrometer (HETGS) on board the {\em Chandra X-ray Observatory}. Numerous absorption lines were detected in the HETGS spectrum. The lines are associated with highly ionized Ne, Na, Mg, Al, Si, S, and Fe, some of which have been seen in earlier HETGS observations. Surprisingly, however, we discovered dramatic variability of the lines over the duration of the present observation. For instance, the flux of the Ne X line at 12.14 Å was about $5 \times 10^{-3}$ photons cm$^{-2}$ s$^{-1}$ in the early part of the observation but became subsequently undetectable, with a 99% upper limit of $0.06 \times 10^{-3}$ photons cm$^{-2}$ s$^{-1}$ on the flux of the line. This implies that the line weakened by nearly two orders of magnitude on a timescale of hours. The overall X-ray flux of the source did also vary during the observation but only by 20--30%. For Cyg X-1, the absorption lines are generally attributed to the absorption of X-rays by ionized stellar wind in the binary system. Therefore, they may provide valuable diagnostics on the physical condition of the wind. We discuss the implications of the results.

Aspects of iron and nitrogen nutrition in two red tide dinoflagellates, Gymnodinium sanguineum Hirasaka and Protogonyaulax tamarensis (Lebour) Taylor
Creators: name: Doucette, Gregory John
Publisher: name: University of British Columbia

description: Iron stress-mediated effects on growth, biochemical composition, iron and nitrogen uptake, and ultrastructure have been examined in the red tide dinoflagellates Gymnodinium sanguineum Hirasaka and Protogonyaulax tamarensis (Lebour) Taylor. The influence of nitrogen source (i.e. NO₃ or NH₄) on certain iron stress-mediated effects was studied, and some comparisons were made with nitrogen stress-mediated changes in biochemical composition The half-saturation constant for iron-limited growth (K[sub μ] = 1.7∙10⁻²⁰ M) of G. sanguineum was estimated to be 10-1000 times greater than for other neritic species investigated previously. Also, the iron requirement of this dinoflagellate, in terms of Fe/C ratios, exceeded those of certain coastal diatoms by one to two orders of magnitude. Fe/N ratios demonstrated a larger (1.5-fold) minimum iron requirement for NO₃- than NH₄-grown cells, likely reflectin the iron content of NO₃ assimilatory enzymes. Acquisition of nitrogen by Fe-deplete, NO₃-grown cells was sufficiently inhibited to yield symptoms of N deficiency, revealed by decreased (ca. 1.4-fold) N quotas and free amino acid/protein ratios compared to Fe-deplete, NH₄-grown cells Reductions in chlorophyll a (chl a) quotas (Q[sub chl]) and photosynthetic electron transport (PET) efficiency (as measured by in vivo fluorescence indices) occurred under Fe depletion, and are consistent with the essential role of iron in chl a and PET component (i.e. cytochromes and Fe-S proteins) biosynthesis. Nitrogen depletion affected Q[sub chl] similarly, but altered PET efficiency to a markedly lesser extent than did Fe depletion. Iron-deplete G. sanguineum exhibited an enhanced iron transport capacity, which failed to be manifested following a transition from NH₄ to NO₃ nutrition. This suppression may result from concurrent iron and nitrogen stress, due to the inability of Fe-deplete, NH₄-grown cells to rapidly assimilate NO₃. The complete initial inhibition of NO₃ uptake when Fe-deplete, NH₄-grown cells were given saturating iron additions supports this idea. Iron stress caused reductions in chloroplast number and some degeneration of lamellar organization in this species. For P. tamarensis, iron limitation induced the formation of temporary (= pellicle) and resting (= hypnozygotes) cysts. Degenerative changes in organelle (i.e. chloroplasts, mitochondria and chromosomes) ultrastructure were largely restricted to pellicular cysts, consistent with their hypothesized role of maintaining viability over brief, rather than extended (cf. hypnozygotes) exposure to adverse conditions.

description: We present Roche tomograms of the G5-G8 IV/V secondary star in the long-period cataclysmic variable BV Cen reconstructed from MIKE echelle data taken on the Magellan Clay 6.5-m telescope. The tomograms show the presence of a number of large, cool starspots on BV Cen for the first time. In particular, we find a large high-latitude spot which is deflected from the rotational axis in the same direction as seen on the K3-K5 IV/V secondary star in the cataclysmic variable AE Aqr. BV Cen also shows a similar relative paucity of spots at latitudes between 40-50 degrees when compared with AE Aqr. Furthermore, we find evidence for an increased spot coverage around longitudes facing the white dwarf which supports models invoking starspots at the L1 point to explain the low-states observed in some cataclysmic variables. In total, we estimate that some 25 per cent of the northern hemisphere of BV Cen is spotted. We also find evidence for a faint, narrow, transient emission line with characteristics reminiscent of the peculiar low-velocity emission features observed in some outbursting dwarf novae. We interpret this feature as a slingshot prominence from the secondary star and derive a maximum source size of 75,000 km and a minimum altitude of 160,000 km above the orbital plane for the prominence. The entropy landscape technique was applied to determine the system parameters of BV Cen. We find M_1 = 1.18 (+0.28 -0.16) Msolar, M_2 = 1.05 (+0.23 -0.14) Msolar and an orbital inclination of i = 53 degrees +- 4 degrees at an optimal systemic velocity of γ= -22.3 km s-1. Finally, we also report on the previously unknown binarity of the G5IV star HD 220492.

description: How to design silicon-based quantum wires with figure of merit ($ZT$) larger than three is under hot pursuit due to the advantage of low cost and the availability of matured fabrication technique. Quantum wires consisting of finite three dimensional quantum dot (QD) arrays coupled to electrodes are proposed to realize high efficient thermoelectric devices with optimized power factors. The transmission coefficient of 3D QD arrays can exhibit 3D, 2D, 1D and 0D topological distribution functions by tailoring the interdot coupling strengths. Such topological effects on the thermoelectric properties are revealed. The 1D topological distribution function shows the maximum power factor and the best $ZT$ value. We have demonstrated that 3D silicon QD array nanowires with diameters below $20~nm$ and length $250~nm$ show high potential to achieve $ZT\ge 3$ near room temperature.

description: We present the first X-ray dedicated study of the galaxy cluster A795 and of the Fanaroff-Riley Type 0 hosted in its brightest cluster galaxy. Using an archival 30 ks \textit{Chandra} observation we study the dynamical state and cooling properties of the intracluster medium, and we investigate whether the growth of the radio galaxy is prevented by the surrounding environment. We discover that A795 is a weakly cool core cluster, with an observed mass deposition rate $\lessapprox 14\,$ M$_{\odot}$yr$^{-1}$ in the cooling region (central $\sim$66 kpc). In the inner $\sim$ 30 kpc we identify two putative X-ray cavities, and we unveil the presence of two prominent cold fronts at $\sim$60 kpc and $\sim$178 kpc from the center, located along a cold ICM spiral feature. The central galaxy, which is offset by 17.7 kpc from the X-ray peak, is surrounded by a multi-temperature gas with an average density of $n_{\text{e}} = 2.14 \times 10^{-2}$ cm$^{-3}$. We find extended radio emission at 74-227 MHz centered on the cluster, exceeding the expected flux from the radio galaxy extrapolated at low frequency. We propose that sloshing is responsible for the spiral morphology of the gas and the formation of the cold fronts, and that the environment alone cannot explain the compactness of the radio galaxy. We argue that the power of the two cavities and the sloshing kinetic energy can reduce and offset cooling. Considering the spectral and morphological properties of the extended radio emission, we classify it as a candidate radio mini-halo.

description: Quantum random walks are the quantum counterpart of classical random walks, and were recently studied in the context of quantum computation. A quantum random walker is subject to self interference, leading to a remarkably different behavior than that of classical random walks such as ballistic propagation or localization due to disorder. Physical implementations of quantum walks have only been made in very small scale systems severely limited by decoherence. Here we show that the propagation of photons in waveguide lattices, which have been studied extensively in recent years, are essentially an implementation of quantum walks. Since waveguide lattices are easily constructed at large scales and display negligible decoherence, they can serve as an ideal and versatile experimental playground for the study of quantum walks and quantum algorithms. We experimentally observe quantum walks in large systems (~100 sites) and confirm quantum walks effects which were studied theoretically, including ballistic propagation, disorder and boundary related effects.

The $e^+ e^-\to K^+ K^- π^+π^-$, $K^+ K^- π^0π^0$ and $K^+ K^- K^+ K^-$ Cross Sections Measured with Initial-State Radiation

description: We study the processes $e^+ e^-\to K^+ K^- π^+π^-γ$, $K^+K^-π^0π^0γ$ and $K^+ K^- K^+ K^-γ$, where the photon is radiated from the initial state. About 34600, 4400 and 2300 fully reconstructed events, respectively, are selected from 232 \invfb of \babar data. The invariant mass of the hadronic final state defines the effective \epem center-of-mass energy, so that the $K^+ K^- π^+π^-γ$ data can be compared with direct measurements of the $e^+ e^-\to K^+K^- \pipi$ reaction; no direct measurements exist for the $e^+ e^-\to K^+ K^- π^0π^0$ or $\epem\to K^+ K^- K^+ K^-$ reactions. Studying the structure of these events, we find contributions from a number of intermediate states, and we extract their cross sections where possible. In particular, we isolate the contribution from $e^+ e^-\toϕ(1020) f_{0}(980)$ and study its structure near threshold. In the charmonium region, we observe the $J/ψ$ in all three final states and several intermediate states, as well as the $ψ(2S)$ in some modes, and measure the corresponding branching fractions. We see no signal for the Y(4260) and obtain an upper limit of $\BR_{Y(4260)\toϕπ^+π^-}\cdotΓ^{Y}_{ee}<0.4 \ev$ at 90% C.L.

Quantifying the impact of vibrational nonequilibrium in plasma catalysis: Insights from a molecular dynamics model of dissociative chemisorption

description: The rate, selectivity and efficiency of plasma-based conversion processes is strongly affected by nonequilibrium phenomena. High concentrations of vibrationally excited molecules are such a plasma-induced effect. It is frequently assumed that vibrationally excited molecules are important in plasma catalysis because their presence lowers the apparent activation energy of dissociative chemisorption reactions and thus increases the conversion rate. A detailed atomic-level understanding of vibrationally stimulated catalytic reactions in the context of plasma catalysis is however lacking. Here, we couple a recently developed statistical model of a plasma-induced vibrational nonequilibrium to molecular dynamics simulations, enhanced sampling methods, and machine learning techniques. We quantify the impact of a vibrational nonequilibrium on the dissociative chemisorption barrier of H2 and CH4 on nickel catalysts over a wide range of vibrational temperatures. We investigate the effect of surface structure and compare the role of different vibrational modes of methane in the dissociation process. For low vibrational temperatures, very high vibrational efficacies are found, and energy in bend vibrations appears to dominate the dissociation of methane. The relative impact of vibrational nonequilibrium is much higher on terrace sites than on surface steps. We then show how our simulations can help to interpret recent experimental results, and suggest new paths to a better understanding of plasma catalysis.

description: The use of meta-schedulers for resource management in large-scale distributed systems often leads to a hierarchy of schedulers. In this paper, we discuss why existing meta-scheduling hierarchies are sometimes not sufficient for Grid systems due to their inability to re-organise jobs already scheduled locally. Such a job re-organisation is required to adapt to evolving loads which are common in heavily used Grid infrastructures. We propose a peer-to-peer scheduling model and evaluate it using case studies and mathematical modelling. We detail the DIANA (Data Intensive and Network Aware) scheduling algorithm and its queue management system for coping with the load distribution and for supporting bulk job scheduling. We demonstrate that such a system is beneficial for dynamic, distributed and self-organizing resource management and can assist in optimizing load or job distribution in complex Grid infrastructures.
