description: It is expected that matter composed of a perfect fluid cannot be at rest outside of a black hole if the spacetime is asymptotically flat and static (non-rotating). However, there has not been a rigorous proof for this expectation without assuming spheical symmetry. In this paper, we provide a proof of non-existence of matter composed of a perfect fluid in static black hole spacetimes under certain conditions, which can be interpreted as a relation between the stellar mass and the black hole mass.

description: The impact of single passive intruders into granular particles has been studied in detail. However, the impact force produced by multiple intruders separated at a distance from one another, and hence the effect of their presence in close proximity to one another, is largely unexplored. Here, we use numerical simulations and laboratory experiments to study the force response of two parallel rods intruding vertically into granular media while varying the gap spacing between them. We also explored the effect of variations in friction, intruder size, and particle size on the force response. The net work ($W$) of the two rods over the depth of intrusion was measured, and the instantaneous velocities of particles over the duration of intrusion were calculated by simulations. We found that the work done by the intruders changes with distance between them. We observed a peak in $W$ at a gap spacing of $\sim$3 particle diameters, which was up to 25% greater than $W$ at large separation (\textgreater 11 particle diameters), beyond which the net work plateaued. This peak was likely due to less particle flow between intruders as we found a larger number of strong forces---identified as force chains---in the particle domain at gaps surrounding the peak force. Although higher friction caused greater force generation during intrusion, the gap spacing between the intruders at which the peak work was generated remained unchanged. Larger intruder sizes resulted in greater net work with the peak in $W$ occurring at slightly larger intruder separations. Taken together, our results show that peak work done by two parallel intruders remained within a narrow range, remaining robust to most other tested parameters.

Celebrating Uncertainty in Qualitative Research

Publisher: name: KULT_online
Year: 2013

description: Edited by Maggi Savin-Baden and Claire Howell Major, New Approaches to Qualitative Research: Wisdom and Uncertainty offers a relevant contribution to the field of qualitative inquiry by highlighting new, emerging approaches to qualitative research. The central guiding concepts of the book are wisdom and uncertainty and the volume is structured accordingly in three parts reflecting on wisdom that underlies uncertainties in stance, approach, and space. The topics addressed range from locating values and truths in qualitative research to questions about responsible ethics, from discussing the benefits of narrative theory and ethnodrama to a qualitative approach to questioning culture through the corporeal and exploring the politics of space. Although the vast majority of contributors come from educational or health research, the explorative approaches tackled here and ethical dilemmas related to a qualitative approach exceed disciplinary borders. This also justifies the editorial claim that the volume is intended for a specialist audience in a broad range of subject areas.

description: We report the first results of relativistic correlation calculation of the spectroscopic properties for the ground state of E112H and its cation in which spin-orbit interaction is taken into account non-perturbatively. Studying the properties of E112 (eka-Hg) is required for chemical identification of its long-lived isotope, $^{283}$112. It is shown that appropriate accounting for spin-orbit effects leads to dramatic impact on the properties of E112H whereas they are not so important for E112H$^+$. The calculated equilibrium distance, $R_e^{calc}=1.662$ A, in E112H is notably smaller than $R_e^{expt}=(1.738\pm0.003)$ A and $R_e^{calc}=1.738$ A in HgH, whereas the dissociation energy, $D_e^{calc}=0.42$ eV, in E112H is close to $D_e^{expt}=0.46$ eV and $D_e^{calc}=0.41$ eV in HgH. These data are quite different from $R_e^{NH}=1.829$ A and $D_e^{NH}=0.06$ eV obtained for E112H within the scalar-relativistic Douglas-Kroll approximation [Nakajima and Hirao, Chem. Phys. Lett., 329, 511 (2000)]. Our results indicate that E112 should not be expected to be "more inert" than Hg in opposite to the results by other authors.

description: The image formation mechanism in Piezoresponse Force Microscopy (PFM) of capacitor structures is analyzed. We demonstrate that the spatial resolution is a bilinear function of film and top electrode thicknesses, and derive the corresponding analytical expressions. For many perovskites, the opposite contributions of d31 and d33 components can result in anomalous domain wall profiles. This analysis establishes the applicability limits of PFM for polarization dynamics studies in capacitors, and applies to other structural probes, including focused X-ray studies of capacitor structures.

description: New Online Database of Symbiotic Variables includes several poorly characterised objects and candidate symbiotic stars, not only in the Milky Way but also in other galaxies. The goal of the research presented in this paper was to reveal the nature of 2MASS J07363415+6538548, the object discovered as an X-ray source in the field of NGC 2403, and tentatively classified as a symbiotic candidate or a cataclysmic variable. By analysis of available photometric data from ground-based surveys, together with high precision photometry from TESS, remarkable astrometric measurements of the Gaia satellite, and observations of other surveys spanning from X-rays to infrared, we have found that the object is not a symbiotic star nor a cataclysmic variable but rather an active K-type dwarf. The star is located in the distance of 415 pc, has an effective temperature of 4 275 K, luminosity of 0.14 L$\odot$, a mass of 0.7 M$\odot$, and radius of 0.7 R$\odot$. It has a rotational period ~ 3 days and is a strong X-ray source with the X-ray luminosity of ~ $10^{30}$ erg/s. Gyrochronology and isochrone fitting confirmed that the star is young.

Bipolar jets growth and decline in Hen 3-1341: a direct link to fast wind and outburst evolution

description: The appearance and disappearance of collimated bipolar jets in the symbiotic star Hen 3-1341 is reported and investigated. From modeling of the emission line spectrum it turns out that the accreting white dwarf in quiescence has T_WD ~ 1.2 10(5) K and R_WD ~ 0.14 Rsun, for a luminosity of 3.8 10(3) Lsun, and it is stably burning hydrogen on the surface at a rate of 5 10(-8) Msun/yr, feeding ionizing photons to a radiation bounded circumstellar nebula extending for ~ 17 AU. The WD underwent a multi-maxima outburst lasting from 1998 to 2004 during which its H-burning envelope reacted to a probable small increase in the mass accretion by expanding and cooling to T_eff ~ 1 10(4) K and R ~ 20 Rsun, mimicking an A-type giant that radiated a total of 6 10(44) erg during the outburst, at an average rate of 1 10(3) Lsun. Bipolar jets developed at the time of outburst maximum and their strength declined in parallel with the demise of a fast wind from the WD, finally disappearing when the wind stopped halfway to quiescence, marking a 1:1 correspondence between jets presence and feeding action of the fast wind. The total mass in the jets was M_jet ~ 2.5 10(-7) Msun for a kinetic energy of E_jet ~ 1.7 10(42)/(sin i) erg, corresponding to 0.3/(sin i) percent of the energy radiated during the whole outburst.

description: The moment of inertia of the pulsar A in the neutron star binary J0737-3039 will soon be measurable through detailed measurements of the periastron advance. We present the calculation of the moment of inertia of neutron stars with the masses of the components of the binary J0737-3039 for a broad range of equations of state of dense matter and discuss the implications of such measurement for constraining the equation of state. An observational determination of the moment of inertia of the pulsar A in J0737-3039 with the accuracy of 10% shall narrow down considerably the range of viable equations of state. We also show that limits on maximal mass of a neutron star provide a complementary set of constraints on the properties of dense nuclear matter.

description: Strong gravitational lensing is an ideal tool for mapping the distribution of dark matter and for testing the values of cosmological parameters. Forthcoming surveys such as Euclid and the Rubin Observatory LSST should increase the number of known strong lensing systems significantly, with for example over 100,000 such systems predicted in the Euclid wide survey. In this short research note we predict that approximately 17,000 strong gravitational lenses will also be detectible in the Nancy Grace Roman Space Telescope 2000 square degree survey, using the LensPop gravitational lensing model. We present predicted distributions in source and deflector redshifts, magnitudes, and magnifications. Although this survey is not primarily designed as a strong lensing detection experiment, it will still provide a large complementary catalogue to shallower, wider-area forthcoming lensing discovery projects.

description: How can we build more just machine learning systems? To answer this question, we need to know both what justice is and how to tell whether one system is more or less just than another. That is, we need both a definition and a measure of justice. Theories of distributive justice hold that justice can be measured (in part) in terms of the fair distribution of benefits and burdens across people in society. Recently, the field known as fair machine learning has turned to John Rawls's theory of distributive justice for inspiration and operationalization. However, philosophers known as capability theorists have long argued that Rawls's theory uses the wrong measure of justice, thereby encoding biases against people with disabilities. If these theorists are right, is it possible to operationalize Rawls's theory in machine learning systems without also encoding its biases? In this paper, I draw on examples from fair machine learning to suggest that the answer to this question is no: the capability theorists' arguments against Rawls's theory carry over into machine learning systems. But capability theorists don't only argue that Rawls's theory uses the wrong measure, they also offer an alternative measure. Which measure of justice is right? And has fair machine learning been using the wrong one?

Switching valley filtered current directions in multi-terminal graphene systems

description: Valley filtering processes have been explored in different graphene-based configurations and scenarios to control transport responses. Here we propose graphene multi-terminal set-ups properly designed to obtain valley filtered currents in a broad range of energy, besides the possibility of controlling their directions. We explore graphene systems with extended mechanical fold-like deformations as an opportunity to enhance valley filtered transmission. The mixing between the electronic confinement effects due to a magnetic field and strain results in a selective drive of the current components in the quantum Hall regime. We adopt the mode-matching method within the Green's function formalism, allowing the direct analysis of the strain effect on each valley transmission. We estimate a threshold map of confinement parameters, characterized by the magnetic, deformation, and set-up lengths, to optimize valley filter transport processes and the proper switch of the valley polarized current directions.

description: O uso de tecnologias digitais em sala de aula tem se tornado cada vez mais discutido em nível institucional e cotidiano. As metodologias ativas ingressam ao cenário educacional brasileiro com possibilidade de mudar os rumos da aprendizagem em Geometria, mas necessitam ser planejadas, executadas e avaliadas de forma estratégica. A partir dessa constatação, o estudo aqui realizado teve objetivo de verificar as potencialidades do uso de tecnologias digitais como o Kahoot, o Quizziz e o Quizlet, ao processo de gamificação voltado para o ensino de Geometria. Mediante abordagem qualitativa, realizou-se uma pesquisa do tipo bibliográfica e investigativa. A análise repercutiu aspectos quanto ao uso da gamificação por meio de tais softwares ao ensino de Geometria, destacando potencialidades como: engajamento dos estudantes nas atividades por meio desses recursos, promoção da motivação devido elementos como competição, pontuação e ranking, discussões e inquietações sobre o conteúdo exposto, retomada de conteúdos e mediação do professor para o processo de ensino. Por fim, percebeu-se que as pesquisas reforçam que o elemento do treinamento é capaz de ofertar conhecimento e segurança na aplicação de metodologias ativas, seja no ensino da Geometria, seja em outras áreas. Da mesma forma, as observações também comprovam que a gamificação precisa ser aprimorada no Brasil.

description: We report on an optical photometric and polarimetric campaign on the accreting millisecond X-ray pulsar (AMXP) SAX J1808.4-3658 during its 2019 outburst. The emergence of a low-frequency excess in the spectral energy distribution in the form of a red excess above the disc spectrum (seen most prominently in z, i and R-bands) is observed as the outburst evolves. This is indicative of optically thin synchrotron emission due to a jet, as seen previously in this source and in other AMXPs during outburst. At the end of the outburst decay, the source entered a reflaring state. The low-frequency excess is still observed during the reflares. Our optical (BVRI) polarimetric campaign shows variable linear polarization (LP) throughout the outburst. We show that this is intrinsic to the source, with low-level but significant detections (0.2-2%) in all bands. The LP spectrum is red during both the main outburst and the reflaring state, favoring a jet origin for this variable polarization over other interpretations, such as Thomson scattering with free electrons from the disc or the propelled matter. During the reflaring state, a few episodes with stronger LP level (1-2 %) are observed. The low-level, variable LP is suggestive of strongly tangled magnetic fields near the base of the jet. These results clearly demonstrate how polarimetry is a powerful tool for probing the magnetic field structure in X-ray binary jets, similar to AGN jets.

description: We present a neural-network emulator for baryonic effects in the non-linear matter power spectrum. We calibrate this emulator using more than 50,000 measurements in a 15-dimensional parameters space, varying cosmology and baryonic physics. Baryonic physics is described through a baryonification algorithm, that has been shown to accurately capture the relevant effects on the power spectrum and bispectrum in state-of-the-art hydrodynamical simulations. Cosmological parameters are sampled using a cosmology-rescaling approach including massive neutrinos and dynamical dark energy. The specific quantity we emulate is the ratio between matter power spectrum with baryons and gravity-only, and we estimate the overall precision of the emulator to be 1-2%, at all scales 0.01 < k < 5 h/Mpc, and redshifts 0 < z < 1.5. We also obtain an accuracy of 1-2%, when testing the emulator against a collection of 74 different cosmological hydrodynamical simulations and their respective gravity-only counterparts. We show also that only one baryonic parameter, namely Mc, which set the gas fraction retained per halo mass, is enough to have accurate and realistic predictions of the baryonic feedback at a given epoch. Our emulator will become publicly available in http://www.dipc.org/bacco.

description: A pandemia provocada pelo vírus SARS-CoV-2 tem-se repercutido fortemente nas rotinas dos adolescentes com impacto na sua saúde física e mental. Esta situação é agravada pelo confinamento e pelo afastamento da comunidade escolar. O estudo tem por objetivo conhecer as perceções dos alunos do 2º e 3º ciclo do ensino básico sobre a COVID-19. O estudo, realizado através de um questionário online, integrou uma amostra de 1743 alunos, dos 11 aos 17 anos, de escolas do concelho de Leiria. Na análise dos dados, através do SPSS22, foi utilizada estatística descritiva, teste Qui-Quadrado, t-Student e um nível de significância de 5% para intervalo de confiança de 95%. Os estudantes possuem um elevado nível de conhecimento acerca da doença e das respetivas medidas de proteção. Apresentam um elevado índice global de preocupação de situações decorrentes da pandemia, sendo que a maioria concorda com o regresso às aulas e admite que as aulas presenciais permitiriam melhores avaliações. Apontam a vacinação como uma medida importante para o controlo da pandemia, mostrando disponibilidade para serem vacinados. Os resultados apontam a necessidade de manter a informação que promova comportamentos que favoreçam a segurança e desmistifiquem os receios da pandemia. A disponibilidade dos alunos para serem vacinados deve ser equacionada numa perspetiva de atingir a imunidade de grupo.

description: We developed a method to detect the quantum nature of high spin molecules using muon spin rotation, and a three-step field cycle ending always with the same field. We use this method to demonstrate that the Fe8 molecule can remember 6 (possibly 8) different histories (bits). A wide range of fields can be used to write a particular bit, and the information is stored in discrete states. Therefore, Fe8 can be used as a model compound for Multi-bit Magnetic Memory. Our experiment also paves the way for magnetic quantum tunneling detection in films.

description: O cenário da educação atual exige várias adaptações e mudanças ante à pandemia da covid-19, portanto, transitando de um ensino presencial para o Ensino Remoto Emergencial(ERE)[1]. Desta forma, a coordenação pedagógica precisa caminhar a passos largos para acompanhar e compreender os processos que se entrelaçam nessa transição de ensino. O estudo visa analisar o Ensino Remoto Emergencial na educação profissional e tecnológica sob o viés das reflexões de um coordenador pedagógico. A construção do texto delineia-se metodologicamente por meio da pesquisa bibliográfica e descritiva. As análises e os resultados apontam a necessidade de flexibilização e de redirecionamento perante os desafios encontrados no percurso do Ensino Remoto Emergencial, e ainda, a viabilidade de formações que permitam ao coordenador pedagógico proporcionar cooperação aos docentes numa visão de colaboração. [1] O termo acompanha o conceito proposto por Behar (2020).

Rocking the Lighthouse: Circumpulsar Asteroids and Radio Intermittency

description: We propose that neutral, circumpulsar debris entering the light cylinder can account for many time-dependent pulsar phenomena that are otherwise difficult to explain. Neutral material avoids propeller ejection and injects sufficient charges -- after heating, evaporation, and ionization -- to alter current flows and pair-production and thus trigger, detune, or extinguish coherent emission. Relevant phenomena, with time scales from seconds to months, include nulls, rotating radio transients (RRATs), rapid changes in pulse profile (``mode changes''), variable subpulse drift rates, quasi-periodic bursts from B1931+24, and torque variations. Over the 10 Myr lifetime of a canonical pulsar with trillion-gauss surface magnetic field, less than a millionth of an Earth mass of material is needed to modulate the Goldreich-Julian current by 100%. Circumpulsar material originates from metal-rich, supernova fallback gas that aggregates into asteroids. Debris disks can inject sufficient material on time scales of interest, yet be too tenuous to form large planets detectable in pulse timing data. Asteroid migration results from collisions and the radiation-driven Yarkovsky and Poynting-Robertson effects. For B1931+24, an asteroid in a $\sim 40$~day elliptical orbit pollutes the magnetosphere stochastically through collisions with other debris. Injection is less likely for hot, young and highly magnetized pulsars or millisecond pulsars that pre-ionize any debris material well outside their small magnetospheres. Injection effects will therefore be most prominent in long-period, cooler pulsars, consistent with the distribution of relevant objects in perid and period derivative. A pulsar's spin history and its radiation-beam orientation may influence whether it displays nulling, RRATs and other effects.

description: O estudo se propôs a investigar os desafios enfrentados para a inclusão das crianças com Transtorno do Espectro Autista-TEA na Educação Infantil. Trata-se de uma pesquisa de cunho qualitativo utilizando como aporte a pesquisa bibliográfica e documental, através de projeto e relatório de estágio, desenvolvidos pelas autoras, a partir de pesquisa e intervenção na Associação de Amigos do Autista-AMA, no componente curricular Pesquisa e estágio em espaços não formais, do curso de Pedagogia da Universidade do Estado da Bahia-UNEB. Observou-se que os principais impasses relacionados ao processo de in/exclusão, na Educação Infantil, pela criança com TEA estão atrelados aos modelos de infância e criança historicamente construídos. Os rígidos padrões de normalidade e os estereótipos criados impedem no espaço escolar, a aceitação das crianças com TEA em toda a sua singularidade. Ao fugirem das regras pré-estabelecidas essas, vivenciam o preconceito praticado como meio de proteção contra os impactos causados pelas diferenças. Faz-se necessário o rompimento com o referido modelo, o que poderá ser possível a partir da compreensão de que o ser criança é uma construção social, que se vivencia a infância de modo singular, não havendo como universalizá-la. A informação e o diálogo constituem-se como elementos imprescindíveis para a compreensão da instituição escolar enquanto um espaço de in/exclusão. Evidencia-se como um dos maiores desafios à inclusão da criança com TEA na Educação Infantil, a desconstrução do significado de inclusão como está posto, dando-lhe um sentido que favoreça o atendimento das demandas de cada sujeito em seu contexto histórico-social.

description: We construct the complete $U$-$μ$ phase diagram for harmonically confined ultracold fermionic atoms with repulsive and attractive interactions. ($μ$ is the chemical potential and $U$ the interaction strength.) Our approach is based on density-functional theory, and employs analytical expressions for the kinetic and correlation energy functionals. For repulsive interactions our calculations confirm previous numerical studies, and complement these by closed expressions for all phase boundaries and characteristic lines of the phase diagram, and by providing an explanation and solution for difficulties encountered in earlier density-functional work on the same system. For attractive interactions we propose a new and accurate interpolation for the correlation energy, and use it to extend the phase diagram to $U<0$.

description: The authors of The New Jewish Argentina. Facets of Jewish Experiences in the Southern Cone offer readers an interesting and well-researched book on Jewish past and current-day experience in Argentina. Their contributions on Argentinean Jewish literature, cinema, history, and society constitute an excellent mixture, allowing us to track the most recent developments in the Latin American Jewish studies. Especially interesting is the focus on minority discourses formerly largely neglected by the scholarship.

description: During outbursts, the observational properties of black hole X-ray binaries (BHXBs) vary on timescales of days to months. These relatively short timescales make these systems ideal laboratories to probe the coupling between accreting material and outflowing jets as a the accretion rate varies. In particular, the origin of the hard X-ray emission is poorly understood and highly debated. This spectral component, which has a power-law shape, is due to Comptonisation of photons near the black hole, but it is unclear whether it originates in the accretion flow itself, or at the base of the jet, or possibly the interface region between them. In this paper we explore the disk-jet connection by modelling the multi-wavelength emission of MAXI J1836-194 during its 2011 outburst. We combine radio through X-ray spectra, X-ray timing information, and a robust joint-fitting method to better isolate the jet's physical properties. Our results demonstrate that the jet base can produce power-law hard X-ray emission in this system/outburst, provided that its base is fairly compact and that the temperatures of the emitting electrons are sub-relativistic. Because of energetic considerations, our model favours mildly pair-loaded jets carrying at least 20 pairs per proton. Finally, we find that the properties of the X-ray power spectrum are correlated with the jet properties, suggesting that an underlying physical process regulates both.
