Year: 2013

description: That the future has come there is no doubt. But there are some countries which have embraced the digital era more than others. South Korea has been well on the vanguard of technology for the last fifteen years. From the latest cell-phone technology to megalomaniac futuristic “U-cities”, South Korea is looking to establish itself as the world leader in technology and science. Being a “new” country, still in search for its place in the world, Korea has come a long way since World War II and the Korean War. Overcoming war, anarchy, dictatorship and deep economic crisis, Korea has been slowly crawling into the international spotlight. But not only technology and science make the core of Korea’s success. The strong will of its people and the visionary political and social stances adopted by the governments of the Sixth Republic1 also helped to shape Korean society into a role-model for the modern Western world. With well-defined goals for the future, Korea should be looked at as an example of the integration of the latest technologies into day-to-day life. This short reflection aims to unveil the secrets of the success of the Asian advent of technologyand its long-lasting relationship with videogames, and to give a glimpse into the future of Western societies.

description: In bilayer systems consisting of an ultrathin ferromagnetic layer adjacent to a metal with strong spin-orbit coupling, an applied in-plane current induces torques on the magnetization. The torques that arise from spin-orbit coupling are of particular interest. Here, we calculate the current-induced torque in a Pt-Co bilayer to help determine the underlying mechanism using first principles methods. We focus exclusively on the analogue to the Rashba torque, and do not consider the spin Hall effect. The details of the torque depend strongly on the layer thicknesses and the interface structure, providing an explanation for the wide variation in results found by different groups. The torque depends on the magnetization direction in a way similar to that found for a simple Rashba model. Artificially turning off the exchange spin splitting and separately the spin-orbit coupling potential in the Pt shows that the primary source of the "field-like" torque is a proximate spin-orbit effect on the Co layer induced by the strong spin-orbit coupling in the Pt.

description: We find the gravity dual of $\mathcal{N}=2^*$ super-Yang-Mills theory on $S^4$ and use holography to calculate the universal contribution to the corresponding $S^4$ free energy at large $N$ and large 't Hooft coupling. Our result matches the expression previously computed using supersymmetric localization in the field theory. This match represents a non-trivial precision test of holography in a non-conformal, Euclidean signature setting.

description: Eugenio Suárez-Galván (2005) en su cuento Extranjero en el estanco afirma: todos somos extranjeros en todos los países del mundo menos en uno. Esta afirmación, interesantemente reveladora, pretende ilustrar el contenido del presente trabajo. Si entendemos que cualquier ser humano tiene el mismo derecho a vivir en cualquier parte del planeta tendremos que convenir que las diferentes administraciones políticas y educativas tendrán que crear las condiciones favorables para que este derecho se pueda ejercer. Para ello, entre otros muchos factores, habrá que considerar que la lengua -las lenguas- es el primer vehículo de identificación cultural y de comunicación entre los seres humanos. La experiencia que presento surge de la coordinación de diversos proyectos de la AECID (Agencia Española para la Cooperación y el Desarrollo) consistentes en la mejora de la formación docente y la investigación en contextos plurilingües. Concretamente hemos desarrollado la experiencia en Perú y en República Dominicana, y en regiones donde el mestizaje de culturas y lenguas dibuja un interesante mosaico para la educación plurilingüe e intercultural.

description: We report on Chandra X-ray observations of four candidate low-mass black hole (<10^6Msun) active galactic nuclei (AGNs) that have the estimated Eddington ratios among the lowest (~10^(-2)) found for this class. The aims are to validate the nature of their AGNs and to confirm the low Eddington ratios that are derived from the broad H_alpha line, and to explore this poorly studied regime in the AGN parameter space. Among them, two objects with the lowest significance of the broad lines are also observed with Multi-Mirror Telescope, and the high-quality optical spectra taken confirm them as Seyfert 1 AGNs and as having small black hole masses. X-ray emission is detected from the nuclei of two of the galaxies, which is variable on timescales of 10^3s, whereas no significant (or only marginal at best) detection is found for the remaining two. The X-ray luminosities are on the order of 10^(41) ergs/s or even lower, on the order of 10^(40) ergs/s for non-detections, which are among the lowest regimes ever probed for Seyfert galaxies. The low X-ray luminosities, compared to their black hole masses derived from H_alpha, confirm their low accretion rates assuming typical bolometric corrections. Our results hint at the existence of a possibly large population of under-luminous low-mass black holes in the local universe. An off-nucleus ultra-luminous X-ray source (ULX) in one of the dwarf galaxies is detected serendipitously, with a luminosity (6-9)x10^(39) ergs/s in 2-10 keV.

description: This paper presents a concurrent learning-based actor-critic-identifier architecture to obtain an approximate feedback-Nash equilibrium solution to an infinite horizon N-player nonzero-sum differential game online, without requiring persistence of excitation (PE), for a nonlinear control-affine system. Under a condition milder than PE, uniformly ultimately bounded convergence of the developed control policies to the feedback-Nash equilibrium policies is established.
DO IMPRESSO AO DIGITAL – DESAFIOS DA HIPERLEITURA. O CASO DOS E-BOOKS

description: As alterações decorrentes da era digital provocam mudanças na experiência da leitura, conduzindo a uma nova forma de ler, com uma designação própria: a hiperleitura (Dresang, 2008; Marcuschi, 2004; Novaes, 2007) e ao desdobramento do conceito de literacia, emergindo, assim, a designação de literacia digital. Esta é entendida não apenas como uma destreza na ótica do utilizador das tecnologias mas também como algo mais complexo que pressupõe competências cognitivas, emocionais, motoras e sociológicas (Eshet-Alkalai, 2004; OCDE, 2011). À hiperleitura tem sido associada uma série de características que classificam o hipertexto (Lévy, 1993; Marcuschi, 2004): multilinearidade, multisequencialidade, volatilidade, espacialidade topográfica, multissemiose, fragmentariedade, interatividade e intertextualidade. Através de uma análise comparativa entre as propriedades do texto impresso e as do hipertexto (texto digital) supramencionadas pretende-se apurar as implicações do suporte digital no modo de o leitor se relacionar com o texto, com vista a uma melhor compreensão de um fenómeno em particular, os livros digitais, inseridos num âmbito mais vasto que é a hiperleitura. Para tal, partir-se-á da análise da categorização dos livros digitais proposta por Len Unsworth (2006) para uma reflexão sobre as particularidades de exemplares de cada uma das categorias em livros eletrónicos nacionais.

description: A recently introduced active phase field crystal model describes the formation of ordered resting and traveling crystals in systems of self-propelled particles. Increasing the active drive, a resting crystal can be forced to perform collectively ordered migration as a single traveling object. We demonstrate here that these ordered migrating structures are linearly stable. In other words, during migration, the single crystalline texture together with the globally ordered collective motion is preserved even on large length scales. Furthermore, we consider self-propelled particles on a substrate that are surrounded by a thin fluid film. We find that in this case the resulting hydrodynamic interactions can destabilize the order.

description: Les concepts de multiculturalité et d’interculturalité font partie de la vie actuelle du monde entier. Ils ont été étudiés et continunte à être étudiés dans la vie quotidienne, le monde du travail et le monde universitaire. Lors d’un stage j’ai voulu mettre en œuvre une étude sur ces deux concepts dans le monde universitaire en choisissant l’Institut Supérieur de Comptabilité et d’Administration de Porto car j’y effectuais un stage. Je voulais démontrer si cet endroit était seulement un lieu multiculturel ou s’il était un lieu à la fois multiculturel et interculturel ou alors s’il se trouvait dans un état intermédiaire. Pour cela, j’ai tout d’abord fait un travail de recherche sur les deux concepts précédemment cités afin d’avoir une base théorique solide puis j’ai continué avec une partie pratique qui consistait dans la réalisation de questionnaires et ensuite la mise en place d’entretiens avec des étudiants et des stagiaires étrangers ainsi qu’avec des étudiants de l’ISCAP. Tout cela dans le but de déterminer les conditions d’accueil des étudiants étrangers, leurs impressions quant à ce séjour à l’étranger et à cette expérience interculturelle ou non et enfin des idées et/ou des mesures pour aider les lieux qui les accueillent afin de perfectionner ces séjours. Pour les étudiants de l’ISCAP, des questions afin de savoir également si l’Institut est un lieu interculturel ainsi que des solutions et/ou des mesures similaires à celles des étudiants étrangers. Tout cela formera une synthèse pour permettre à ces étudiants et stagiaires d’avoir une véritable situation interculturelle.

MULTILINGUALISM AND INTERPRETING TRAINING FOR THE EU
Creators: name: Matias, Helena
Publisher: name: POLISSEMA – Revista de Letras do ISCAP
Year: 2013

description: This article context is located in the realm of multiculturalism and multilingualism as characteristics of modern Europe. Addressing this issue, Peter Hans Nelde affirms that “Language planning and language policy have thus become established in the cultural planning of the EU members in such a way that they are now even recognized by outsiders” (Nelde, 2007: 60). According to my interpretation of his words, the language planning policy of the EU members should also pay attention to the second generation immigrants who return to their parents' homeland, Portugal, which is the focus of this article among bilinguals. I wish to address bilingualism in the training of Conference Interpreting, approaching multilingualism in the context of the European institutions as potential working places for our students and trainees in their future professional field, that is, interpreting. According to Joanne Winter and Anne Pauwels, “the second generations are seen as threats or challenges to language maintenance as well as potential transformers for bi/multilingualism and linguistic diversity” (Winter & Pauwels, 2007: 180). I approach the issue from another perspective: the contribution that the second generation can give to the market place after having been trained in higher education because bilinguals are fundamental in the field of conference interpreting. The current analysis is inspired by my own post-graduation as a student at ETI (Geneva’s University “École de Traduction et Interprètation”), the experience of briefly Matias, Helena Anacleto - Multilingualism and Interpreting Training for the EU 67-84 68 Polissema – Revista de Letras do ISCAP – Vol.13 - 2013 interpreting at the European Parliament, in the late nineteen eighties, in Brussels, Luxembourg and Strasbourg, by the experience of training interpreters for twelve years and from the analysis of specialized literature on the subject.

description: The Fisher Information Matrix (FIM) has been the standard approximation to the accuracy of parameter estimation on gravitational-wave signals from merging compact binaries due to its ease-of-use and rapid computation time. While the theoretical failings of this method, such as the signal-to-noise ratio (SNR) limit on the validity of the lowest-order expansion and the difficulty of using non-Gaussian priors, are well understood, the practical effectiveness compared to a real parameter estimation technique (e.g. Markov-chain Monte Carlo) remains an open question. We present a direct comparison between the FIM error estimates and the Bayesian probability density functions produced by the parameter estimation code lalinference_mcmc. In addition to the low-SNR issues usually considered, we find that the FIM can greatly overestimate the uncertainty in parameter estimation achievable by the MCMC. This was found to be a systematic effect for systems composed of binary black holes, with the disagreement increasing with total mass. In some cases, the MCMC search returned standard deviations on the marginalized posteriors that were smaller by several orders of magnitude than the FIM estimates. We conclude that the predictions of the FIM do not represent the capabilities of real gravitational-wave parameter estimation.

description: We present a simple toy model to understand what sets the scatter in star formation and metallicity of galaxies at fixed mass. The scatter ultimately arises from the intrinsic scatter in the accretion rate, but may be substantially reduced depending on the timescale on which the accretion varies compared to the timescale on which the galaxy loses gas mass. This model naturally produces an anti-correlation between star formation and metallicity at a fixed mass, the basis of the fundamental metallicity relation. We show that observational constraints on the scatter in galaxy scaling relations can be translated into constraints on the galaxy-to-galaxy variation in the mass loading factor, and the timescales and magnitude of stochastic accretion onto star-forming galaxies. We find a remarkably small scatter in the mass loading factor, < 0.1 dex, and that the scatter in accretion rates is smaller than expected from N-body simulations.

description: O presente artigo consiste na análise da tradução para inglês do livro A Crise da Europa, de Abel Salazar, e pretende explicar a metodologia utilizada no processo tradutivo e as opções que foram tomadas na produção do texto de chegada. O protocolo celebrado entre a Casa-Museu Abel Salazar e o ISCAP deu o mote a esta colaboração que tem como objetivo final a edição da obra traduzida, possibilitando que o legado de Abel Salazar esteja cada vez mais acessível a um número crescente de pessoas. Este trabalho pretende não só, tornar disponível a obra do autor a novos públicos através da sua publicação na que é hoje a língua universal – o inglês –, mas também dar conta de quem foi Abel Salazar em toda a sua soberba pluralidade. O livro foi escrito entre 1937 e 1942, pelo que o desfasamento temporal que separa o autor da tradutora resultou, necessariamente, numa pesquisa sobre a evolução da língua portuguesa, tendo em conta os diversos acordos ortográficos que a têm vindo a modelar, como, de resto, tão bem o sentimos, neste momento particular. O distanciamento temporal entre o autor / texto fonte e o tradutor / texto de chegada é, igualmente, analisado com recurso a exemplos que o demonstram e clarificam a postura metodológica da tradutora.

description: Daksha, a proposed Indian mission, will be the most sensitive all-sky high-energy time domain telescope in the world. Daksha will detect and characterise about ten electromagnetic counterparts of the gravitational wave (EMGW) events per year and about thousand classical GRBs (especially high redshift GRBs) per year. For bright transients, Daksha will be able to measure hard X-ray polarisation, a key to understanding the geometry and physical process of the emission mechanism. The mission will consist of two identical satellites monitoring the entire sky in the energy range of 1 – 1000 keV and with all-sky median effective area of ~1300 cm2 for a single satellite and an effective fluence sensitivity of 4 × 10–8 erg/cm2 (for a 1 second duration transient). Daksha will have 340 pixelated Cadmium Zinc Telluride (CZT) detectors on each satellite arranged in a quasi-hemispherical configuration and without any field of view collimation (open detectors). These CZT detectors form an excellent polarimeter capable of measuring photon polarisation in the energy range 100 – 400 keV. The CZTI instrument aboard AstroSat has successfully measured the polarisation of the Crab pulsar and 11 GRBs using these detectors. In this work, we introduce the Daksha mission concept, discuss details of the polarisation measurement method using the CZT detectors, and show results of simulations carried out using the mass model to estimate polarisation measurement sensitivity of the Daksha mission.

description: In this work we study the effect of the symmetry energy on several properties of neutron stars. First, we discuss its effect on the density, proton fraction and pressure of the neutron star crust-core transition. We show that whereas the first two quantities present a clear correlation with the slope parameter $L$ of the symmetry energy, no satisfactory correlation is seen between the transition pressure and $L$. However, a linear combination of the slope and curvature parameters at $ρ=0.1$ fm$^{-3}$ is well correlated with the transition pressure. In the second part we analyze the effect of the symmetry energy on the pasta phase. It is shown that the size of the pasta clusters, number of nucleons and the cluster proton fraction depend on the density dependence of the symmetry energy: a small $L$ gives rise to larger clusters. The influence of the equation of state at subsaturation densities on the extension of the inner crust of the neutron star is also discussed. Finally, the effect of the effect of the density dependence of the symmetry energy on the strangeness content of neutron stars is studied in the last part of the work. It is found that charged (neutral) hyperons appear at smaller (larger) densities for smaller values of the slope parameter $L$. A linear correlation between the radius and the strangeness content of a star with a fixed mass is also found.

description: We present an alternative methodology for calculating the quasi-particle energy, energy loss, and optical spectra of a molecule deposited on graphene or a metallic substrate. To test the accuracy of the method it is first applied to the isolated benzene (C6H6) molecule. The quasiparticle energy levels and especially the energies of the benzene excitons (triplet, singlet, optically active and inactive) are in very good agreement with available experimental results. It is shown that the vicinity of the various substrates (pristine/doped graphene or (jellium) metal surface) reduces the quasiparticle HOMO-LUMO gap by an amount that slightly depends on the substrate type. This is consistent with the simple image theory predictions. It is even shown that the substrate does not change the energy of the excitons in the isolated molecule. We prove (in terms of simple image theory) that energies of the excitons are indeed influenced by two mechanisms which cancel each other. We demonstrate that the benzene singlet optically active (E1u) exciton couples to real electronic excitations in the substrate. This causes it substantial decay, such as Γ = 174 meV for pristine graphene and Γ = 362 meV for metal surfaces as the substrate. However, we find that doping graphene does not influence the E1u exciton decay rate.

description: O presente estudo reporta a citologia de uma mulher de 66 anos, que apresenta um epitélio atrófico com fundo inflamatório. Identificaram-se agregados tridimensionais de células glandulares com sobreposição celular, anisocariose, aumento nuclear, hipercromasia moderada, presença de nucléolos e cromatina grosseira, irregularmente distribuída. O diagnóstico citológico foi de células glandulares atípicas sem outra especificação, com inflamação. Posteriormente, realizou-se uma biópsia cujo diagnóstico foi carcinoma endometrial de tipo endometrióide. A paciente foi submetida a histerectomia total com anexectomia bilateral, confirmando-se o diagnóstico da biópsia. O diagnóstico de células glandulares atípicas é definido pela presença de células glandulares com alterações que ultrapassam as reativas/reparativas, mas sem características inequívocas de adenocarcinoma. No follow-up a maioria destes casos representa uma condição benigna. No entanto, um subconjunto significativo revela uma lesão pavimentosa de alto grau ou uma lesão neoplásica glandular, não sendo incomum a associação entre o diagnóstico de células glandulares atípicas e a presença de adenocarcinomas do colo uterino, endométrio, ovário e trompa de Falópio. A citologia tem uma especificidade relativamente elevada na deteção de patologia endometrial, apresentando um papel preponderante no diagnóstico de neoplasias. Neste caso, o reconhecimento de células glandulares atípicas, conduziu ao diagnóstico de carcinoma endometrial.

description: We consider LHC searches for dark matter in the mono-Higgs channel using the tools of effective field theory. This channel takes unique advantage of the presence of $SU(2)_L$ breaking in those operators to avoid the need for any initial-state radiation, usually necessary to tag the production of invisible particles. We find that sensitivities to parameters describing dark matter interactions with standard model particles are comparable to those from monojet searches for a subset of the usually-considered operators, and we present for the first time bounds from collider searches on operators which couple DM to only the Higgs field or its covariant derivatives.

description: O carcinoma adenoescamoso é um tumor raro que representa cerca de 4% dos tumores cervicais. Este carcinoma ocorre maioritariamente em mulheres com cerca de 50 anos, podendo ocorrer em mulheres mais jovens e está também associado ao estado de gravidez e à infeção pelo Papiloma Vírus Humano. No presente trabalho, relata-se o caso de uma mulher de 45 anos, com coitorragias e uma lesão dura, elevada e hemorrágica no colo do útero, que foi submetida a citologia esfoliativa. O exame microscópico permitiu visualizar achados citológicos compatíveis com coexistência de componente pavimentosa- células pleomórficas com citoplasma denso com aumento da relação núcleo citoplasma - e componente glandular- pseudoestratificação, feathering e núcleos alongados. O relatório citológico foi de carcinoma pavimento celular, não excluindo a possibilidade de carcinoma adenoescamoso. No seguimento da doente, foi realizada biópsia ao colo uterino, cujo diagnóstico histológico foi de adenocarcinoma invasor produtor de muco com uma componente do tipo pavimentoso. Esta neoplasia faz diagnóstico diferencial principalmente com “tumores de colisão” onde ocorrem duas neoplasias primárias, uma glandular e outra pavimentosa. Para este tipo de tumor, a interpretação citológica pode ser desafiante, pela dificuldade de interpretar nos aspetos citomorfológicos a componente pavimentosa e glandular na mesma amostra.

description: A ocorrência simultânea de duas neoplasias malignas primárias é uma condição pouco frequente, predisposta por fatores ambientais e genéticos. Descrevemos o caso clínico de uma mulher de 50 anos, fumadora, com diagnóstico de linfoma linfocítico/ leucemia linfocítica crónica (LLC). Após a deteção de um nódulo no lobo superior do pulmão direito e de múltiplas adenopatias mediastínicas, foi efetuada broncofibroscopia com citologia aspirativa transbrônquica por agulha fina guiada por ecografia endobrônquica dirigida aos gânglios linfáticos mediastínicos. Na amostra citológica identificaram-se células epiteliais malignas, que expressavam a proteína Fator de Transcrição da Tiroide 1 (TTF1) por imunocitoquímica, e uma população monomórfica de linfócitos cuja análise por citometria de fluxo caracterizou como linfoma linfocítico. Concluímos a existência de duas neoplasias no mesmo grupo adenopático: linfoma linfocítico e metástase de adenocarcinoma do pulmão. Este caso confirma os dados da literatura, que recomendam que o follow-up dos doentes com LLC deve contemplar a procura de tumores sólidos, dado estes doentes terem maior probabilidade de os desenvolver, nomeadamente tumores primários do pulmão, sendo o adenocarcinoma o mais frequente.

description: Objetivo O presente artigo pretende expor um caso de ausência de correlação entre os exames colposcópico, citológico e histológico. Apresentação do caso Numa consulta de ginecologia de rotina, a paciente, de 54 anos, realizou uma citologia ginecológica em meio líquido, cuja observação microscópica resultou no diagnóstico de carcinoma epidermóide. Posteriormente, a paciente foi encaminhada para uma sequência de consultas de follow-up, tendo realizado uma biópsia do colo que demonstrou marcada atrofia, sendo negativa para lesão intraepitelial; uma pesquisa e tipificação do vírus do Papiloma Humano positiva para os genótipos 35 e 56 (alto risco); e uma conização, da qual resultou um diagnóstico de lesão intraepitelial pavimentosa de baixo grau. Discussão Após a realização de pesquisa bibliográfica que relatasse exemplos de casos de discrepância entre a colposcopia, a citologia e a histologia, verificou-se que os falsos negativos, tanto na colposcopia, como nos exames histológicos, bem como a sobrevalorização do diagnóstico citológico, poderão ser hipóteses causais para a disparidade de resultados apresentados neste caso. Conclusão Este estudo remete para a importância da correlação entre a citologia e a histologia, assim como a necessidade de comunicação entre os vários profissionais de saúde das diversas áreas envolvidas.

description: CONTEXT: The dynamical mass-to-light (M/L) ratios of massive ultra-compact dwarf galaxies (UCDs) are about 50% higher than predicted by stellar population models. AIMS: Here we investigate the possibility that these elevated M/L ratios are caused by a central black hole (BH), heating up the internal motion of stars. We focus on a sample of ~50 extragalactic UCDs for which velocity dispersions and structural parameters have been measured. METHODS: Using up-to-date distance moduli and a consistent treatment of aperture and seeing effects, we calculate the ratio Psi=(M/L)_{dyn}/(M/L)_{pop} between the dynamical and the stellar population M/L of UCDs. For all UCDs with Psi>1 we estimate the mass of a hypothetical central BH needed to reproduce the observed integrated velocity dispersion. RESULTS: Massive UCDs (M>10^7 M_*) have an average Psi = 1.7 +-0.2, implying notable amounts of dark mass in them. We find that, on average, central BH masses of 10-15% of the UCD mass can explain these elevated dynamical M/L ratios. The implied BH masses in UCDs range from several 10^5 M_* to several 10^7 M_*. In the M_BH-Luminosity plane, UCDs are offset by about two orders of magnitude in luminosity from the relation derived for galaxies. Our findings can be interpreted such that massive UCDs originate from progenitor galaxies with masses around 10^9 M_*, and that those progenitors have SMBH occupation fractions of 60-100%. The suggested UCD progenitor masses agree with predictions from the tidal stripping scenario. Lower-mass UCDs (M<10^7 M_*) exhibit a bimodal distribution in Psi, suggestive of a coexistence of massive globular clusters and tidally stripped galaxies in this mass regime. CONCLUSIONS: Central BHs as relict tracers of tidally stripped progenitor galaxies are a plausible explanation for the elevated dynamical M/L ratios of UCDs.

description: Introduction: Hospitalization increases the risk of a subsequent diagnosis of dementia. We aimed to identify diagnoses or events during a hospitalization requiring critical care that are associated with a subsequent dementia diagnosis in the elderly. Methods: A cohort study of a random 5% sample of Medicare beneficiaries who received intensive care in 2005 and survived to hospital discharge, with three years of follow-up (through 2008) was conducted using Medicare claims files. We defined dementia using the International Classification of Diseases, 9th edition, clinical modification (ICD-9-CM) codes and excluded patients with any prior diagnosis of dementia or cognitive impairment in the year prior to admission. We used an extended Cox model to examine the association between diagnoses and events associated with the critical illness and a subsequent diagnosis of dementia, adjusting for known risk factors for dementia. Results: Over the three years of follow-up, dementia was newly diagnosed in 4,519 (17.8%) of 25,368 patients who received intensive care and survived to hospital discharge. After accounting for known risk factors, having an infection (adjusted hazard ratio (AHR) = 1.25; 95% CI, 1.17 to 1.35), or a diagnosis of severe sepsis (AHR = 1.40; 95% CI, 1.28 to 1.53), acute neurologic dysfunction (AHR = 2.06; 95% CI, 1.72 to 2.46), and acute dialysis (AHR = 1.70; 95% CI, 1.30 to 2.23) were all independently associated with a subsequent diagnosis of dementia. No other measured ICU factors, such as need for mechanical ventilation, were independently associated. Conclusions: Among ICU events, infection or severe sepsis, neurologic dysfunction, and acute dialysis were independently associated with a subsequent diagnosis of dementia. Patient prognostication, as well as future research into post-ICU cognitive decline, should focus on these higher-risk subgroups.

description: We investigate the neutron and proton single particle (s.p.) potentials of asymmetric nuclear matter and their isospin dependence in various spin-isospin $ST$ channels within the framework of the Brueckner-Hartree-Fock approach. It is shown that in symmetric nuclear matter, the s.p. potentials in both the isospin-singlet T=0 channel and isospin-triplet T=1 channel are essentially attractive, and the magnitudes in the two different channels are roughly the same. In neutron-rich nuclear matter, the isospin-splitting of the proton and neutron s.p. potentials turns out to be mainly determined by the isospin-singlet T=0 channel contribution which becomes more attractive for proton and more repulsive for neutron at higher asymmetries.

Comparing galaxy populations in compact and loose groups of galaxies II: brightest group galaxies

description: The properties of the brightest galaxies (BCGs) are studied in both compact and loose groups of galaxies in order to better understand the physical mechanisms influencing galaxy evolution in different environments. Samples of BCGs are selected in the compact groups identified by McConnachie et al. (2009), and in loose groups taken from Zandivarez & Martínez (2011). The following physical properties of the BCGs in compact groups and in subsamples of loose groups are compared, defined by their mass and total luminosity. The fraction of BCGs classified as red and/or early-type as a function of galaxy luminosity are studied. The fraction of the group's total luminosity contained in the BCG and the difference in luminosity between the BCG and the second-ranked galaxy, are also analysed. Some properties of BCGs in compact and loose groups are comparable. However, BCGs in compact groups are systematically more concentrated and have larger surface brightness than their counterparts in both, high- and low-mass loose groups. The fractions of red and early-type BCGs in compact groups are consistent with those of high-mass loose groups. Comparing BCGs in subsamples of compact and loose groups selected for their similar luminosities, BCGs in compact groups are found to be, on average, brighter, more massive, larger, redder and more frequently classified as elliptical. In compact groups, the BCG contains a larger fraction of the system's total luminosity and differs more in absolute magnitude from the second-ranked galaxy. BCGs in compact and loose groups are found to be different. Some mechanisms responsible for transforming late-type galaxies into early types, such as mergers, may be more effective within compact groups due to their high densities and small velocity dispersion, which would lead their BCGs along somewhat different evolutionary paths.
