description: Young protostars embedded in circumstellar discs accrete from an angular momentum-rich mass reservoir. Without some braking mechanism, all stars should be spinning at or near break-up velocity. In this paper, we perform simulations of the self-gravitational collapse of an isothermal cloud using the ORION adaptive mesh refinement code and investigate the role that gravitational torques might play in the spin-down of the dense central object. While magnetic effects likely dominate for low mass stars, high mass and Population III stars might be less well magnetised. We find that gravitational torques alone prevent the central object from spinning up to more than half of its breakup velocity, because higher rotation rates lead to bar-like deformations that enable efficient angular momentum transfer to the surrounding medium. We also find that the long-term spin evolution of the central object is dictated by the properties of the surrounding disc. In particular, spiral modes with azimuthal wavenumber $m=2$ couple more effectively to its spin than the lopsided $m=1$ mode, which was found to inhibit spin evolution. We suggest that even in the absence of magnetic fields, gravitational torques may provide an upper limit on stellar spin, and that moderately massive circumstellar discs can cause long-term spin down.

description: Este trabalho aborda as dificuldades do processo de ensino e aprendizagem durante o período de isolamento social e os desafios de trabalhar os resultados da avaliação externa SAEPE (Sistema de Avaliação Educacional de Pernambuco) para o alcance de melhores resultados em outras avaliações externas. São objetivos deste estudo: identificar as dificuldades do processo de ensino e aprendizagem no período de isolamento social e analisar a importância de trabalhar os resultados da avaliação externa (SAEPE) para redirecionamento do trabalho pedagógico. Trata-se de uma pesquisa de abordagem qualitativa e exploratória. Através de acompanhamentos e observações em uma escola pública de Ensino Médio no município de Bom Jardim/PE, foi realizado um estudo com professores, estudantes, gestão e funcionários sobre o contexto educacional em que estamos vivendo. Assim, constatamos que são grandes os desafios e que precisamos nos adequar a nova forma de trabalhar nesse modelo de ensino remoto emergencial, identificando as prioridades do processo de ensino e aprendizagem. Para superação das dificuldades e desafios, a escola reorganizou todo trabalho pedagógico, foram realizadas reuniões online; atendimentos individualizados, através de mensagens nas redes sociais, elaboração de planos pedagógicos; utilização de plataformas para aulas virtuais e outras metodologias. Os resultados do SAEPE 2019 foram divulgados em abril durante a pandemia e, a partir da divulgação, houve vários encontros online com professores, funcionários e a gestão para estudos e análises do que foi apresentado para que houvesse o redirecionamento do trabalho pedagógico.

description: A recente crise pandémica marcou a ação dos profissionais da Intervenção Precoce na Infância (IPI), conduzindo a mudanças nos modos de agir com as crianças, famílias e equipas (educativas, terapêuticas e médicas). O isolamento social trouxe a necessidade de reinventar possibilidades e utilizar a tecnologia, a fim de possibilitar a continuidade no apoio às crianças e famílias, bem como na articulação com todos os profissionais envolvidos no processo. O presente artigo tem como objetivo apresentar os resultados de um estudo de caso sobre o impacto da pandemia na especificidade de intervenção com uma criança com perturbação do espetro de autismo (PEA) e sua família. Trata-se de uma investigação com uma abordagem com características de investigação-ação, de natureza qualitativa, de índole interventiva e, eminentemente, compreensiva e interpretativa. As técnicas para a recolha de informação foram a entrevista semiestruturada e a consulta documental. Os resultados demonstram que o formato de intervenção “à distância” contribuiu para atingir alguns dos objetivos definidos no plano individual de intervenção precoce (PIIP) do André, reforçando a importância da intervenção se realizar em contexto natural, nos momentos das rotinas e nas experiências diárias da criança, em interação com pessoas e contextos familiares. Por outro lado, ampliou os momentos de partilha de informação com a família e com os outros profissionais e corroborou a importância da humanização das relações como base de construção de modos de intervenção, independentemente dos meios e das respostas “de emergência” que os tempos de confinamento vieram trazer ao papel do profissional de IPI.

description: The role of teachers has evolved from a religious-based regimented job requiring no more than high school, GCE or qualifications to one that operates at the intersections of research, policy, and practice. Teaching is now understood as a social, ideological and political practice requiring knowledge, attitudes, behaviors and skills necessary to demonstrate global best practice. Using case study of selected school teachers in Cross River State Nigeria, this paper looks at the confluence of teacher beliefs as informed by culture and how these beliefs drive classroom practices. A combination of observation and semi-structured interviews were used to collect data which was phenomenologically analyzed.

description: We explore the kinematical effect of having extra dimensions on the gravity wave emission from cosmic strings. Additional dimensions both round off cusps, and reduce the probability of their formation. We recompute the gravity wave burst, taking into account these two factors, and find a potentially significant damping on the gravity waves of the strings.

description: In this work the interaction of helium with intensive XUV-pulses is investigated numerically to interpret the experiments (june 2016) performed at FLASH (Free-Electron-Laser in Hamburg). For this purpose the helium atom can be regarded as a few-level-model, furthermore the electron-correlation as well as the coupling with the continuum are considered. The time-dependent Schrödinger equation of the system is solved with discrete time steps. The result is an intensity dependent variation of the observed 2s2p resonance's line shape. This variation is explained by an energy-change induced phase-shift. With this, results and explanations of similar experiments using intense IR-pulses and weak high harmonics can be conrmed. First steps of the inuence on this line shape variation due to noisy XUV-pulses produced at FLASH are investigated as well.

description: Systems with long-range interactions show a variety of intriguing properties: they typically accommodate many meta-stable states, they can give rise to spontaneous formation of supersolids, and they can lead to counterintuitive thermodynamic behavior. However, the increased complexity that comes with long-range interactions strongly hinders theoretical studies. This makes a quantum simulator for long-range models highly desirable. Here, we show that a chain of trapped ions can be used to quantum simulate a one-dimensional model of hard-core bosons with dipolar off-site interaction and tunneling, equivalent to a dipolar XXZ spin-1/2 chain. We explore the rich phase diagram of this model in detail, employing perturbative mean-field theory, exact diagonalization, and quasiexact numerical techniques (density-matrix renormalization group and infinite time evolving block decimation). We find that the complete devil's staircase -- an infinite sequence of crystal states existing at vanishing tunneling -- spreads to a succession of lobes similar to the Mott-lobes found in Bose--Hubbard models. Investigating the melting of these crystal states at increased tunneling, we do not find (contrary to similar two-dimensional models) clear indications of supersolid behavior in the region around the melting transition. However, we find that inside the insulating lobes there are quasi-long range (algebraic) correlations, opposed to models with nearest-neighbor tunneling which show exponential decay of correlations.

description: We present and discuss different protocols for preparing an arbitrary quantum state of a qubit using only a restricted set of measurements, with no unitary operations at all. We show that an arbitrary state can indeed be prepared, provided that the available measurements satisfy certain requirements. Our results shed light on the role that measurement-induced back-action plays in quantum feedback control and the extent to which this back-action can be exploited in quantum-control protocols.

description: The gain-assisted plasmonic analogue of electromagnetically induced transparency (EIT) in a metallic metamaterial is investigated for the purpose to enhance the sensing performance of the EIT-like plasmonic structure. The structure is composed of three bars in one unit, two of which are parallel to each other (dark quadrupolar element) but perpendicular to the third bar (bright dipolar element), The results show that, in addition to the high sensitivity to the refractive-index fluctuation of the surrounding medium, the figure of merit for such active EIT-like metamaterials can be greatly enhanced, which is attributed to the amplified narrow transparency peak.

description: Durante o ano de 2020, o Brasil foi impactado pelos efeitos de um vírus que impossibilitou que aulas presenciais continuassem ocorrendo no âmbito nacional. Para que estudantes tivessem acesso ao conhecimento, as legislações nacionais permitiram que o ensino ocorresse de forma remota durante o período de pandemia. Isso repercutiu em professores utilizando diferentes tecnologias digitais (TD). Com o objetivo de verificar como estavam sendo utilizadas as TD nos processos nacionais de ensino durante a pandemia da COVID-19, realizamos uma investigação qualitativa. Entrevistamos 123 professores, por meio de um questionário no Google Forms, em abril de 2020. A análise das respostas obtidas indicou diferentes possibilidades e dificuldades dos professores. Das principais dificuldades pontuadas, constatou-se o fato de muitos estudantes não terem acesso às TD e limitações dos professores em articular o uso delas no processo de ensino. Quanto aos pontos positivos, os professores perceberam oportunidades de conhecer e utilizar variadas TD para comunicação em videoconferências, com os envolvidos nos processos educacionais, assim como adoção de variados recursos digitais, oportunizando aulas diferenciadas aos alunos. Por fim, alguns professores indicaram que o uso de TD no ensino não irá substituir o papel do professor em aulas presenciais, sobretudo na Educação Básica, mas a adoção do ensino remoto, no período de pandemia, impactará diretamente as práticas pedagógicas no retorno das atividades presenciais.

A semi-automated assay for radiation-induced intestinal damage in mice
Creators: name: Liu, Nan Nan
Publisher: name: University of British Columbia

description: Purpose: The effectiveness of radiotherapy to eradicate cancers is limited by normal tissue that is inevitably included in the irradiated volume. Drugs are being developed with the hope of increasing the therapeutic ratio between tumour cell eradication and normal tissue damage. Improvements in assays to measure normal tissue toxicity are needed. This thesis summarizes the development of a semi-automated intestinal assay with three analysis models - crypt proliferation assessing S-phase cells, villi morphology assessing villi size and DNA damage assessing DNA double strand breaks (DSBs). We use computer automation to address issues such as subjective assessment of damage. Methods: Mice were irradiated with 0-15 Gy x-rays and euthanized at 48 h, 3.5 day and 1–24 h for proliferation, morphology and DNA damage models respectively. Mice received 5-Ethynyl-2’-deoxyuridine (EdU) to stain S-phase cells. A 5 cm length of the jejunum was collected, cut open, wrapped to form a swirl and frozen for cryosectioning. Cryosections (10 µm) of the jejunal swirl were stained and imaged using a robotic microscope; images were processed using ImageJ software. EdU was identified via histochemical staining and the proliferation model reports the proportion of pixels positive for EdU per length of the jejunum. Endothelial cells were identified using immunostaining for CD31, with the villi morphology model reporting the length of villi capillary beds. γH2AX was stained to quantify DSBs, with the DNA damage model reporting the amount of DSBs. A statistical power and assay sensitivity analysis were performed to estimate the detectable effect size and robustness to variability. Results: Proliferation and length of villi were inversely related to radiation dose and the intensity of γH2AX was inversely related to time post-irradiation. Applying to future drug evaluations, power analysis estimates that both proliferation and morphology models can detect EdU and villi length alterations >20%, while the DNA damage model can detect γH2AX modifications >10%. Sensitivity analysis showed that the proliferation model could withstand <30% random error while both morphology and damage models could withstand <15%. Conclusion: A semi-automated intestinal assay was developed with three models applicable to assessing the effects of radiation dose-modifying drugs in intestinal tissue.

description: Experimental studying of non-equilibrium 2D plasmons in a GaN/AlGaN heterostructure with a metal grating was performed. Dips were experimentally detected in the transmission spectra at the resonant frequencies of 2D plasmons at various temperatures. Intense peaks in the emission spectra associated with non-equilibrium 2D plasmons were experimentally detected. The position of the resonant peaks is in good agreement with the results of the simulation of the transmission and absorption spectra made by solving Maxwell's equations. The effective temperature of hot electrons was determined using the I-V characteris-tics and their analysis using the power balance equation. It has been shown for a given electric field the effective temperature of nonequilibrium 2D plasmons is close to the hot 2D electron temperature.

description: Este artigo tem como objetivo compreender como tem acontecido o ensino remoto para os alunos com deficiência em escolas da rede municipal de ensino de Fortaleza. Trata-se de um estudo de abordagem qualitativa cujos sujeitos foram professores do Atendimento Educacional Especializado (AEE) da rede municipal de Fortaleza que acompanham alunos com deficiência nas Salas de Recursos Multifuncionais. Os dados foram produzidos a partir de um questionário estruturado no Google Forms e enviado por meio do aplicativo de mensagem WhatsApp. Para análise dos dados, optamos pela análise textual discursiva. Os resultados apontam para escassez de orientações e recursos tecnológicos disponibilizados pela Secretaria Municipal da Educação, caracterizando-se o ensino, nesse período, pela utilização de recursos digitais pessoais dos professores (internet, computadores, aplicativos de conversa) e aplicação de atividades definidas por eles como flexibilizadas, diferenciadas e lúdicas, disponibilizadas pela escola aos pais dos alunos. A ausência de recursos tecnológicos, plataformas educativas e internet para alunos e professores restringiu as interações educativas a aplicativos de conversas que se mostraram insuficientes para garantir a participação e o acesso ao currículo por parte dos estudantes com deficiência. O estudo evidenciou que as problemáticas vivenciadas na inclusão de estudantes com deficiência na escola comum no cotidiano escolar permaneceram e ampliaram-se durante o ensino remoto ofertado no período de pandemia de Covid-19.

description: Manipulation of light-beams with subwavelenth metallic devices has motivated intensive studies, following the discovery of extraordinary transmission of electromagnetic waves through sub-wavelength apertures in thin noble-metal films. The propagation of light in these holes can be investigated at greately improved spatial resolution by means of focused electron-beams. Here we demonstrate direct e-beam excitation of radiative cavity modes well below the surface plasmon (SP) frequency, of isolated rectangular holes in gold films, illuminating the hotly debated phenomenon of the extraordinary optical transmission through subwavelength holes. The exceptionally long range e-beam interaction with the metal through the vacuum, involving electromagnetic excitations within the light cone, is allowed by momentum conservation breakdown along the e-beam axis. Two types of lowlying excited modes are revealed: radiative cavity modes which are nearly unaffected by SPs, and SP polariton modes with waveguide character in the near field region of the slit walls, which in spite of the strong hybridization preserve the waveguide cutoff frequencies and symmetry characteristics.

From fast to slow light in a resonantly driven absorbing medium

description: We theoretically study the propagation through a resonant absorbing medium of a time-dependent perturbation modulating the amplitude of a continuous wave (cw). Modeling the medium as a system of two-level atoms and linearizing the Maxwell-Bloch equations for the perturbation, we establish an exact analytical expression of the transfer function relating the Fourier transforms of the incident and transmitted perturbations. It directly gives the gain and the phase shift undergone in the medium by a harmonic modulation. For the case of a pulse modulation, it enables us to determine the transmission time of the pulse center-of-mass (group delay), evidencing the relative contributions of the coherent and incoherent (population) relaxation. We show that the group delay has a negative value (fast light) fixed by the coherent effects when the cw intensity is small compared to the saturation intensity and becomes positive (slow light) when this intensity increases, before attaining a maximum that cannot exceed the population relaxation time. The analytical results are completed by numerical determinations of the shape of the transmitted pulses in the different regimes.

description: We wish to study an application of Stueckelberg's relativistic quantum theory in the framework of general relativity. We study the form of the wave equation of a massive body in the presence of a Schwarzschild gravitational field. We treat the mathematical behavior of the wavefunction also around and beyond the horizon (r=2M). Classically, within the horizon, the time component of the metric becomes spacelike and distance from the origin singularity becomes timelike, suggesting an inevitable propagation of all matter within the horizon to a total collapse at r=0. However, the quantum description of the wave function provides a different understanding of the behavior of matter within the horizon. We find that a test particle can almost never be found at the origin and is more probable to be found at the horizon. Matter outside the horizon has a very small wave length and therefore interference effects can be found only on a very small atomic scale. However, within the horizon, matter becomes totally "tachionic" and is potentially "spread" over all space. Small location uncertainties on the atomic scale become large around the horizon, and different mass components of the wave function can therefore interfere on a stellar scale. This interference phenomenon, where the probability of finding matter decreases as a function of the distance from the horizon, appears as an effective gravitational repulsion.

description: The time irreversible evolution of the two-nucleus spin systems interacting with a magnetic field is analyzed in the framework of the subdynamics theory. The spin systems are determined by the H(1) and C(13) nuclei. The investigation is based on the complex spectral representation of the Liouvillian which gives a rigorous description of irreversibility. The evolution of the density matrix is analyzed for the short and long time region. Quantum Zeno effect is discussed.
