description: The space of light rays $\mathcal{N}$ of a conformal Lorentz manifold $(M,\mathcal{C})$ is, under some topological conditions, a manifold whose basic elements are unparametrized null geodesics. This manifold $\mathcal{N}$, strongly inspired on R. Penrose's twistor theory, keeps all information of $M$ and it could be used as a space complementing the spacetime model. In the present review, the geometry and related structures of $\mathcal{N}$, such as the space of skies $Σ$ and the contact structure $\mathcal{H}$, are introduced. The causal structure of $M$ is characterized as part of the geometry of $\mathcal{N}$. A new causal boundary for spacetimes $M$ prompted by R. Low, the $L$-boundary, is constructed in the case of $3$-dimensional manifolds $M$ and proposed as a model of its construction for general dimension. Its definition only depends on the geometry of $\mathcal{N}$ and not on the geometry of the spacetime $M$. The properties satisfied by the $L$-boundary $\partial M$ permit to characterize the obtained extension $\overline{M}=M\cup \partial M$ and this characterization is also proposed for general dimension.

Spectrum synthesis for radially pulsating stars with shocked atmospheres

description: SPEC_PULS describes a suite of computer programs to simulate the emergent spectrum from a radially-pulsating star. It combines a Christy-type non-linear pulsation code with classical stellar atmosphere codes. The principal aim is to interpret the dynamical spectrum of the radially pulsating extreme helium star V652 Her, which shows a strong shock at minimum radius. The components are general enough to treat other classes of radial pulsation. The theoretical spectrum from a shocked pulsation model shows line doubling, with the blue component emerging at standstill velocity and accelerating blueward. The doubling phase depends on line depth and parent ion. The behaviour of line cores post-shock points to a drop in the ionization temperature, although the gas temperature in the model remains high. Shock compression leads to phase-dependent strengthening of Stark-broadened line wings, with the far wings responding first. With velocity, temperature and pressure-sensitive diagnostics, detailed tomography of the pulsation-driven shock in V652 Her seems possible. Even when no shock is present, the dynamical spectrum is significantly different from a model in hydrostatic equilibrium. Using the quasi-static approximation (e.g. at maximum radius) may lead to a considerable underestimate of the star's mean effective temperature and surface gravity.

description: We study graphene in a two-dimensional dynamical noncommutative space in the presence of a constant magnetic field. The model is solved using perturbation theory and to the second order of perturbation. The energy levels of the system are calculated and the corresponding eigenstates are obtained. For all cases, the energy shift depends on the dynamical noncommutative parameter τ. Using the accuracy of energy measurement we put an upper bound on the noncommutativity parameter τ. In addition, we investigate some of the thermodynamic quantities of the system at zero temperature limit and extreme relativistic case, which reveals interesting differences between commutative and dynamical noncommutative spaces.

description: We present a novel method for including the effects of early (pre-supernova) feedback in simulations of galaxy evolution. Rather than building a model which attempts to match idealized, small-scale simulations or analytic approximations, we rely on direct observational measurements of the time-scales over which star-forming molecular clouds are disrupted by early feedback. We combine observations of the spatial de-correlation between molecular gas and star formation tracers on $\sim100$~pc scales with an analytic framework for the expansion of feedback fronts driven by arbitrary sources or mechanisms, and use these to constrain the time-scale and momentum injection rate by early feedback. This allows us to directly inform our model for feedback from these observations, sidestepping the complexity of multiple feedback mechanisms and their interaction below the resolution scale. We demonstrate that this new model has significant effects on the spatial clustering of star formation, the structure of the ISM, and the driving of outflows from the galactic plane, while preserving the overall regulation of the galaxy-integrated star formation rate. We find that this new feedback model results in galaxies that regulate star formation through the rapid disruption of star-forming clouds, rather than by highly efficient, global galactic outflows. We also demonstrate that these results are robust to stochasticity, degraded numerical resolution, changes in the star formation model parameters, and variations in the single free model parameter that is unconstrained by observations.

Positional stability of skyrmions in a racetrack memory with notched geometry

description: Magnetic skyrmions are chiral spin textures with attractive features, such as ultra-small size, solitonic nature, and easy mobility with small electrical currents that make them promising as information-carrying bits in low-power high-density memory, and logic applications. However, it is essential to guarantee the positional stability of skyrmions for reliable information extraction. Using micromagnetic simulations for the minimum energy path (MEP), we compute the energy barriers associated with stabilizing notches along a racetrack. We vary material parameters, specifically, the strength of the chiral Dzyaloshinskii-Moriya interactions (DMI), the notch geometry, and the thickness of the racetrack to get the optimal barrier height. We find that the reduction of skyrmion size as it squeezes past the notch gives rise to the energy barrier. We find a range of energy barriers up to ~ 45 kBT for a racetrack of 5 nm thickness that can provide years long positional lifetime of skyrmions for long-term memory applications while requiring a moderate amount of current (~ 10^10 A/m2) to move the skyrmions. Furthermore, we derive quasi-analytical equations to estimate the energy barrier. We also explore other pinning mechanisms, such as a local variation of material parameters in a region, and find that notched geometry provides the highest energy barrier. Our results open up possibilities to design practical skyrmion-based racetrack geometries for spintronics applications.

description: We aim to determine the intrinsic far-Infrared (far-IR) emission of X-ray-luminous quasars over cosmic time. Using a 16 deg^2 region of the Stripe 82 field surveyed by XMM-Newton and Herschel Space Observatory, we identify 2905 X-ray luminous (LX > 10^42 erg/s) Active Galactic Nuclei (AGN) in the range z ~ 0-3. The IR is necessary to constrain host galaxy properties such as star formation rate (SFR) and gas mass. However, only 10% of our AGN are detected both in the X-ray and IR. Because 90% of the sample is undetected in the far-IR by Herschel, we explore the mean IR emission of these undetected sources by stacking their Herschel/SPIRE images in bins of X-ray luminosity and redshift. We create stacked spectral energy distributions from the optical to the far-IR, and estimate the median star formation rate, dust mass, stellar mass, and infrared luminosity using a fitting routine. We find that the stacked sources on average have similar SFR/L_bol ratios as IR detected sources. The majority of our sources fall on or above the main sequence line suggesting that X-ray selection alone does not predict the location of a galaxy on the main sequence. We also find that the gas depletion timescales of our AGN are similar to those of dusty star forming galaxies. This suggests that X-ray selected AGN host high star formation and that there are no signs of declining star formation.

description: Die vorliegende Diplomarbeit befasst sich mit der Fragestellung, wie sich Identität in weiblichen, bäuerlichen Lebenserinnerungen des 20. Jahrhunderts gestaltet. Identität als lebenslang stattfindender Prozess kann dabei mithilfe zahlreicher unterschiedlicher Ideen und Konzepten erläutert werden. Hinsichtlich der Gattung Autobiographie sind die Vorgänge des Erlebens, Erinnerns und Erzählens sowie deren Wechselwirkungen von besonderer Relevanz. Die theoretische Einführung dieser Diplomarbeit soll hierbei nicht nur einen Einblick in unterschiedliche Identitätstheorien bieten, sondern insbesondere auch den Erinnerungsbegriff und den sozialhistorischen Kontext der bäuerlichen Lebenswelten ins Zentrum stellen. Als literarische Beispiele dienen zwei Autobiographien, welche besonders eindrucksvolle Zeugnisse der gesellschaftlichen, sozialen und insbesondere geschlechtlichen Normen der Zeit darstellen. Anna Wimschneiders („Herbstmilch“) und Barbara Passruggers („Hartes Brot“ bzw. „Steiler Hang“) Autobiographien werden anhand unterschiedlicher Fragestellungen analysiert und interpretiert. Die Ausführungen stützen sich in erster Linie auf die Entwicklung von Identität und beziehen dabei insbesondere jene Lebensbereiche mit ein, die im bäuerlichen Umfeld von besonderer Bedeutung waren.

description: A spin-triplet superconducting state mediated by ferromagnetic (FM) spin fluctuations has been suggested to occur in the newly discovered heavy-fermion superconductor UTe$_2$. However, the recent neutron scattering measurements revealed the presence of antiferromagnetic (AFM) spin fluctuations in UTe$_2$. Here, we report the $^{125}$Te nuclear magnetic resonance (NMR) studies of a single-crystal UTe$_2$, suggesting the coexistence of FM and AFM spin fluctuations in UTe$_2$. Owing to the two different Te sites in the compound, we conclude that the FM spin fluctuations are dominant within ladders and the AFM spin fluctuations originate from the inter-ladder magnetic coupling. Although AFM spin fluctuations exist in the system, the FM spin fluctuations in the ladders may play an important role in the appearance of the spin-triplet superconducting state of UTe$_2$.

description: We analyze nonlinear optics schemes for generating pairs of quantum entangled plasmons in the terahertz-infrared range in graphene. We predict that high plasmonic field concentration and strong optical nonlinearity of monolayer graphene enables pair-generation rates much higher than those of conventional photonic sources. The first scheme we study is spontaneous parametric down conversion in a graphene nanoribbon. In this second-order nonlinear process a plasmon excited by an external pump splits into a pair of plasmons, of half the original frequency each, emitted in opposite directions. The conversion is activated by applying a dc electric field that induces a density gradient or a current across the ribbon. Another scheme is degenerate four-wave mixing where the counter-propagating plasmons are emitted at the pump frequency. This third-order nonlinear process does not require a symmetry-breaking dc field. We suggest nano-optical experiments for measuring position-momentum entanglement of the emitted plasmon pairs. We estimate the critical pump fields at which the plasmon generation rates exceed their dissipation, leading to parametric instabilities.

description: Introdução: A febre de causa infecciosa é frequente e justifica muitas admissões nos Serviços de Urgência Pediátrica. De entre os exames complementares, por vezes necessários nestas situações, estão as hemoculturas.

Objectivo: Analisar as hemoculturas positivas por germens patogénicos no nosso Serviço de Urgência, nomeadamente os agentes mais frequentes, sua evolução, os respectivos antibiogramas e correlação com alguns dados clínicos.

Material e Métodos: Avaliação retrospectiva dos dados microbiológicos referentes aos germens patogénicos isolados nas hemoculturas colhidas em crianças febris, com idade até aos 13 anos, admitidas no nosso Serviço de Urgência entre 1995 e 2005. Análise de dados clínicos referentes aos últimos 6 anos (2000-2005).

Resultados: Entre 1995 e 2005 foram isoladas 159 germens patogénicos, sendo os mais frequentes a Neisseria meningitidis (41 casos; 25,8%), Escherichia coli (24; 15%), Staphylococcus aureus (22; 13,8%), Streptococcus pneumoniae (19; 11,9%) e Salmonella spp (16; 10%). Nos últimos 6 anos o S. pneumoniae foi a segunda bactéria mais frequentemente isolada e 88% eram susceptíveis ou tinham susceptibilidade intermédia à penicilina. Todas as estirpes de N. meningitidis eram susceptíveis à ampicilina e não foram encontrados S. aureus resistentes à meticilina. Neste período, 70% das crianças com hemoculturas positivas por germens patogénicos tinham idade inferior a 36 meses e faleceram 3, todas devido a choque séptico.

Conclusão: Ao longo dos últimos anos os germens patogénicos isolados em hemoculturas no Serviço de Urgência, mantiveram-se relativamente estáveis, bem como as suas susceptibilidades. A N. meningitidis e o S. pneumoniae são actualmente os predominantes. A monitorização dos dados microbiológicos é muito importante, em termos epidemiológicos e clínicos.

description: In screening models with scalar-matter conformal coupling, we study the flavor transition of neutrinos. We employ an analytical method for studying the oscillation phase in a spherically symmetric spacetime filled by a scalar field. Since the ambient matter density determines the scalar field's behavior, an indirect environmental effect contributes to the flavor conversion inside matter. We evaluate the survival probabilities and show that the existence of the scalar field affects the oscillations of neutrinos. We discuss the results in the framework of screening mechanisms and the end, confront our results with observational data.

As implicações legais e financeiras desta prescrição motivaram a criação de um grupo de trabalho com a finalidade de conhecer a realidade portuguesa.

Objectivo: Efectuar o levantamento das situações com potencial necessidade de monitorização domiciliária. Quantificar e caracterizar os monitores cardio-respiratórios e oxímetros de pulso utilizados e os motivos para prescrição.

Métodos: Foram enviados pelo correio 60 exemplares do inquérito para 56 hospitais com Serviço de Pediatria. Aceitou-se resposta telefónica.

Resultados: Obtiveram-se 44 respostas (73%); 29 em suporte escrito e 15 por telefone. A prematuridade constituiu o principal motivo de utilização domiciliária de monitores cardio-respiratórios (93%) e maioritariamente na região da Grande Lisboa. A prescrição de oxímetros de pulso verificou-se dispersa por todo o País para crianças com doença respiratória crónica, muitas dos quais com dependência tecnológica.

Conclusão: A monitorização cardio-respiratória domiciliária deve ser abordada de modo distinto de acordo com os dois grandes grupos de indicações. Os monitores cardio-respiratóriosmais utilizados são descritos como tendo pequena sensibilidade e especificidade para detectar episódios dos diferentes tipos de apneia. A necessidade de racionalizar os recursos técnicos e financeiros, disponíveis no nosso país, exige homogeneização de critérios de prescrição e o planeamento de regras de utilização dos monitores cardio-respiratórios e oxímetros de pulso.

description: Resumo: A Síndrome de Pearson é uma citopatia mitocondrial, rara, que envolve o sistema hematopoiético, habitualmente fatal na infância. Apresenta-se o caso de uma criança de 20 meses de idade, que aos 18 meses de vida iniciou vómitos alimentares, de início esporádicos e que se tornaram persistentes no dia anterior ao internamento, associados a prostração e hipotonia axial. A investigação laboratorial revelou alterações sugestivas de anemia macrocítica, colestase, acidose tubular renal e acidose láctica grave. O estudo molecular do ADN mitocondrial mostrou uma delecção simples de grande tamanho nos tecidos de biópsia muscular, fígado e sangue, sugestivas de Síndrome de Pearson. A criança faleceu durante o internamento por desequilíbrio electrolítico grave refractário à terapêutica. Salienta-se a importância de considerar o diagnóstico de doença do ADN mitocondrial em doentes com sintomatologia multissistémica não atribuível a uma causa específica.

description: Post-common envelope binary systems evolve when matter is transferred from the primary star at a rate that cannot be accommodated by its secondary companion. A common envelope forms which is subsequently ejected resulting in a system with a binary period frequently between 2 and 3 hours. Where circumbinary companions are predicted, it remains unclear whether they form before or after the common envelope ejection. From observations of eclipse time variations (ETVs), exoplanet databases e.g. NASA Exoplanet Archive, list typically a dozen systems with confirmed circumbinary planets. Here we examine seven of these systems, discuss other possible causes and consider whether, for these dynamic systems, the ETV methodology is a reliable indicator of planetary companions. The systems selected were those where we could determine precise eclipse timings, free from significant extraneous effects such as pulsations, and present 163 new times of minima permitting us to test existing models. Over thirty circumbinary models have been proposed for these seven systems and note all, other than the latest model for NY Vir which remains to be fully tested, fail within a year to accurately predict eclipse times. In examining alternative mechanisms we find that magnetic effects could contribute significantly in two of the seven systems studied. We conclude that the structure of these dynamic systems, with the extreme temperature differences and small binary separations, are not fully understood and that many factors may contribute to the observed ETVs.

description: Resumo: A síndrome hipertensiva hiponatrémica (SHH) é uma forma rara de apresentação da doença renovascular em idade pediátrica. Descrevemos o caso de uma menina de quatro anos transferida para a Unidade de Cuidados Intensivos Pediátricos por quadro de cefaleias, prostração e convulsões generalizadas, sem febre. Apresentava hipertensão arterial (HTA) grave e alterações hidroelectrolíticas características, pelo que se fez o diagnóstico de SHH. O estudo etiológico realizado culminou no achado de estenose da artéria renal direita. A angioplastia, realizada como opção terapêutica, levou à reversão completa do quadro clínico em pouco tempo. A relevância deste caso reside na importância de uma avaliação de rotina da tensão arterial, que pode contribuir para o diagnóstico precoce e redução da morbilidade e mortalidade associadas ás formas de HTA grave na criança.

description: Teaching the noncommutativity of the product of matrices to high school or college level students is a difficult task when approached from a purely formal perspective. The aim of this paper is to present a simple experimental activity for teaching the noncommutativity of the matrix product, based on the Jones calculus, a mathematical formalism for describing polarised light by means of matrices and vectors. This activity can also be useful to introduce students to the use of matrices in physics, and to illustrate how abstract mathematics can become a powerful tool to help us explain and describe the real world.

Vacinas na criança com imunodeficiência
Creators: name: Vieira, Marisa

Publisher: name: Portuguese Journal of Pediatrics
Year: 2014

description: Resumo: Apesar das imunodeficiências serem doenças relativamente raras em Pediatria, nos últimos anos temos assistido a um aumento do número de casos, quer pelo número crescente de crianças com imunodeficiências secundárias (à corticoterapia prolongada, quimioterapia ou à infecção pelo vírus da imunodeficiência humana), quer pelo aparecimento de novas imunodeficiências primárias. Paralelamente, tem-se verificado uma maior longevidade destas crianças e o alargamento do leque de vacinas disponíveis. Torna-se necessário, portanto, a existência de recomendações consensuais sobre a vacinação destas crianças, embora nem sempre existam estudos sólidos que as suportem. Os autores pretendem resumir os princípios gerais e os aspectos particulares da imunização da criança com imunodeficiência, tomando como principais referências as recomendações dos colégios de Pediatria inglês e americano, do Programa Nacional de Vacinação e a experiência clínica da sua Unidade. De um modo geral, as vacinas devem ser administradas desde que sejam seguras, mesmo que a sua eficácia seja duvidosa. Na prática, administramos as vacinas inactivadas e contra-indicamos as vacinas vivas.

A VASPR pode, contudo, ser administrada em situações pontuais. Na presença de imunodeficiência combinada grave, primária ou secundária, é mais sensato protelar a vacinação até que se verifique a reconstituição imunitária. Nesta altura, podem estar indicados reforços vacinais suplementares ou mesmo a revacinação de crianças entretanto imunizadas. Os familiares e prestadores de cuidados de crianças com imunodeficiência devem ser submetidos a um leque alargado de imunizações, embora sejam necessários cuidados especiais com a administração de vacinas vivas potencialmente transmissíveis.

Pneumonia adquirida na comunidade. Orientações para actua- ção em Pediatria
Creators: name: Guedes Vaz, Luísa
Publisher: name: Portuguese Journal of Pediatrics
Year: 2014

description: A pneumonia adquirida na comunidade (PAC) continua a ser uma das principais causas de morbilidade/mortalidade em idade pediátrica. Em Portugal, a incidência anual de internamentos em Pediatria, por PAC é de cerca de 30/1000. A Secção de Pneumologia da Sociedade Portuguesa de Pediatria considera importante a uniformização de conceitos de diagnóstico e terapêutica empírica na PAC, de modo a que seja possível avaliar os resultados obtidos e corrigir algumas práticas. Neste trabalho fornecem-se orientações de actuação perante a criança com pneumonia adquirida na comunidade. Os recémnascidos e as crianças com patologia prévia, nomeadamente imunodeficiências, têm especificidades de tratamento que não serão consideradas neste trabalho.
