description: A class of solutions describing the interior of a static spherically symmetric compact anisotropic star is reported. The analytic solution has been obtained by utilizing the Finch and Skea ({\it Class. Quant. Grav.} {\bf 6} (1989) 467) ansatz for the metric potential $g_{rr}$ which has a clear geometric interpretation for the associated background space-time. Based on physical grounds appropriate bounds on the model parameters have been obtained and it has been shown that the model admits an equation of state (EOS) which is quadratic in nature.

description: We examine galaxy groups from the present epoch to z = 1 to explore the impact of group dynamics on galaxy evolution. We use group catalagues from the Sloan Digital Sky Survey (SDSS), the Group Environment and Evolution Collaboration (GEEC) and the high redshift GEEC2 sample to study how the observed member properties depend on galaxy stellar mass, group dynamical mass and dynamical state of the host group. We find a strong correlation between the fraction of non-star-forming (quiescent) galaxies and galaxy stellar mass, but do not detect a significant difference in the quiescent fraction with group dynamical mass, within our sample halo mass range of 10^13-10^14.5 M_sun, or with dynamical sate. However, at a redshift of approximately 0.4 we do see some evidence that the quiescent fraction in low mass galaxies (log(M_star/M_sun) < 10.5) is lower in groups with substructure. Additionally, our results show that the fraction of groups with non-Gaussian velocity distributions increases with redshift to roughly z = 0.4, while the amount of detected substructure remains constant to z = 1. Based on these results, we conclude that for massive galaxies (log(M_star/M_sun_ > 10.5), evolution is most strongly correlated to the stellar mass of a galaxy with little or no additional effect related to either the group dynamical mass or dynamical state. For low mass galaxies, we do see some evidence of a correlation between the quiescent fraction and the amount of detected substructure, highlighting the need to probe further down the stellar mass function to elucidate the role of the environment in galaxy evolution.

description: Frequency blueshifting was recently observed in light pulses propagating on gas filled hollow-core photonic crystal fibers where a plasma has been produced due to photoionization of the gas. One of the propagation models that is adequate to describe the actual experimental observations is here investigated. It is a nonlinear Schrödinger equation with an extra term, to which we applied a self-similar change of variables and found its accelerating solitons. As in other NLS related models possessing accelerating solitons, there exist asymmetrical pulses that decay as they propagate in some parameter region that was here well defined.

description: The CHIRON spectrometer is a new high-resolution, fiber-fed instrument on the 1.5 meter telescope at Cerro Tololo Inter-America Observatory (CTIO). To optimize use of the instrument and limited human resources, we have designed an integrated set of web applications allowing target submission, observing script planning, nightly script execution and logging, and access to reduced data by multiple users. The unified and easy to use interface has dramatically reduced the time needed to submit and schedule observations and improved the efficiency and accuracy of nightly operations. We present our experience to help astronomers and project managers who need to plan for the scope of effort required to commission a queue-scheduled facility instrument.

description: Purpose of the research The paper aims at establishing a relationship between sector openings in Area Control Centres, rostering flexibility in place and the number of controllers needed. We also explore the impact of rostering practices on productivity and spare capacity in the system. Methodology The proposed approach includes an initial mathematical model for optimizing staffing requirements in area control centres, which has been tested on a case study involving three centres, reflecting different hourly variability in demand. Model parameters and assumptions are based on the results of a comprehensive survey on capacity management and rostering practices in Europe and Asia. Research findings The paper clearly shows the impact of flexible rostering and varying daily demand profiles on the number of controllers needed. Namely, for different combinations of shift patterns and demand profiles there is a substantial variation in both the minimum number of controllers and the associated spare capacity. Also, it is shown that certain amount of spare capacity is inevitably present in the system and associated cost implications are briefly discussed. Contribution Only a handful of research contributions addressing rostering of air traffic controllers have been published in the past decade, most of which were focused on local problems and/or testing different solving approaches. There have been hardly any attempts to examine the relationship between demand profile, sector openings, staffing needs and associated spare capacity at area control centres in a more systematic way, which is considered to be the main contribution.

description: The csv file contains behavioural data from a virtual reality (VR) experiment. The aim of the study was to investigate the effect of error attribution and body representation on sensorimotor adaptation in VR. All participants went through three phases: the baseline phase, in which their baseline pointing performance was measured, the exposure phase, in which the virtual environment was visually displaced, and the de-exposure phase, in which the virtual displacement was removed. In all phases, the horizontal distance of the pointer from the target was measured in cm. Participants were assigned to one of three groups: the control group, the misinformation group in which error attribution was manipulated, and the arrow group in which body representation was manipulated. Questionnaires were completed before and after the VR experience. The pdf file "README" contains the explanations for each variable as well as a list and schematic illustration of all target points.
Einstein as armchair detective: The case of stimulated radiation

description: Einstein was in many ways like a detective on a mystery trail, though in his case he was on the trail of nature's mysteries and not some murder mystery! And like all good detectives he had a style. It consisted of taking facts that he knew were correct and forcing nature into a situation that would contradict this established truth. In this process she would be forced to reveal some new truths. Einstein's 1917 paper on the quantum theory of radiation is a classic example of this style and enabled him to predict the existence of stimulated radiation starting from an analysis of thermodynamic equilibrium between matter and radiation.

description: We investigated the detailed inner jet structure of M87 using the Very Long Baseline Array data at 2, 5, 8.4, 15, 23.8, 43, and 86 GHz, especially focusing on the multi-frequency properties of the radio core at the jet base. First, we measured a size of the core region transverse to the jet axis, defined as $W_{\rm c}$, at each frequency ν, and found a relation between $W_{\rm c}$ and $ν$ as $W_{\rm c}(ν) \propto ν^{-0.71\pm0.05}$. Then, by combining $W_{\rm c}(ν)$ and the frequency dependence of the core position $r_{\rm c}(ν)$, which was obtained by our previous study, we have constructed a collimation profile of the innermost jet $W_{\rm c}(r)$ down to ~10 Schwarzschild radii ($R_{\rm s}$) from the central black hole. We found that $W_{\rm c}(r)$ smoothly connects with the width profile of the outer edge-brightened, parabolic jet, and then follows a similar radial dependence down to several tens of $R_{\rm s}$. Closer to the black hole, the measured radial profile suggests a possible change of the jet collimation shape from the outer parabolic one, in which the jet shape tends to become more radially-oriented. This could be related to a magnetic collimation process or/and interaction with surrounding materials at the jet base. The present results shed light on the importance of higher-sensitivity/resolution imaging studies for M87 at 86, 43 and also 22 GHz, and should be examined more rigorously.

Optical and X-ray emission from stable millisecond magnetars formed from the merger of binary neutron stars

description: The coalescence of binary neutron stars (NSs) may in some cases produce a stable massive NS remnant rather than a black hole. Due to the substantial angular momentum from the binary, such a remnant is born rapidly rotating and likely acquires a strong magnetic field (a `millisecond magnetar'). Magnetic spin-down deposits a large fraction of the rotational energy from the magnetar behind the small quantity of mass ejected during the merger. This has the potential for creating a bright transient that could be useful for determining whether a NS or black hole was formed in the merger. We investigate the expected signature of such an event, including for the first time the important impact of electron/positron pairs injected by the millisecond magnetar into the surrounding nebula. These pairs cool via synchrotron and inverse Compton emission, producing a pair cascade and hard X-ray spectrum. A fraction of these X-rays are absorbed by the ejecta walls and re-emitted as thermal radiation, leading to an optical/UV transient peaking at a luminosity of ~1e43-1e44 erg/s on a timescale of several hours to days. This is dimmer than predicted by simpler analytic models because the large optical depth of electron/positron pairs across the nebula suppresses the efficiency with which the magnetar spin down luminosity is thermalized. Nevertheless, the optical/UV emission is more than two orders of magnitude brighter than a radioactively powered `kilonova.' In some cases nebular X-rays are sufficiently luminous to re-ionize the ejecta, in which case non-thermal X-rays escape the ejecta unattenuated with a similar peak luminosity and timescale as the optical radiation. We discuss the implications of our results for the temporally extended X-ray emission that is observed to follow some short gamma-ray bursts (GRBs), including the kilonova candidates GRB 080503 and GRB 130603B.

description: We present a versatile computational image rendering software of optically-acquired holograms. The reported software can process 4 Megapixel 8-bit raw frames from a sensor array acquired at a sustained rate of 80 Hz. Video-rate image rendering is achieved by streamline image processing with commodity computer graphics hardware. For time-averaged holograms acquired in off-axis optical configuration with a frequency-shifted reference beam, wide-field imaging of one tunable spectral component is permitted. This software is validated by phase-stepped hologram rendering, and non-contact monitoring of surface acoustic waves by single and dual sideband hologram rendering. It demonstrates the suitability of holography for video-rate computational laser Doppler imaging in heterodyne optical configuration.

description: The fabrication of low-cost and mechanically robust flexible electronic patterns has increasingly gained attention due to their growing applications in flexible displays, touch screen panels, medical devices, and solar cells. Such applications require cost-effective deposition of metals in a well-controlled manner potentially using nanoparticles (NPs). The presence of solvent and precursors in NP based inks impacts the electrical conductivity of the printed pattern and a post-processing heating step is typically performed to restore the electrical properties and structure of the material. We report printing with picolitre droplet volumes of silver (Ag) NPs on flexible substrates using an acoustic microdroplet dispenser. The low-cost, controlled deposition of Ag ink is performed at room temperature on photopaper, polyimide and clear polyimide substrates. A localized, ultrashort pulsed laser with minimal heat affected zone is employed to sinter printed Ag patterns. For comparison, oven sintering is performed, and the results are analysed with scanning electron microscopy, four-point probe and Hall measurements. The femtosecond laser sintering revealed highly organized, connected nanostructure that is not achievable with oven heating. A significant decrease in sheet resistance, up to 93% in Ag NPs on clear polyimide confirms the laser sintering improves the connectivity of the printed film and as a result, the electrical properties are enhanced. The surface morphology attained by the laser sintering process is interpreted to be due to a joining of NPs as a result of a solid-state diffusion process in the near surface region of NPs.

description: A Lei n.º 82-D/2014, de 31 de dezembro, conhecida por Lei da Fiscalidade Verde, altera e cria um conjunto de novas normas fiscais ambientais, em muitos aspetos impulsionadas pela legislação comunitário e os compromissos internacionais assumidos pelo Estado português, tendo em vista, por um lado, reorientar os comportamentos dos cidadãos e penalizar fiscalmente os comportamentos mais nocivos e, por outro, aumentar as fontes de receita fiscal. Esta reforma fiscal ambiental não pretende resolver todos os problemas ambientais, mas contribuir para um ambiente mais saudável, conjuntamente com outras políticas relacionadas direta ou indiretamente com as questões ambientais. Esta reforma da tributação ambiental, acompanhada por sucessivas alterações legislativas, cuja mais recente releva da Lei n.º 114/2017, de 29/12, altera um conjunto de normas fiscais a nível, nomeadamente, do Código do IRS, do Código do IRC, do Código do IVA, do Código do IMI, do Código do Imposto sobre Veículos, do Código dos Impostos Especiais de Consumo e do Estatuto dos Benefícios Fiscais. Com estas alterações, pretende-se, por um lado, reduzir ou redistribuir a carga fiscal, mas também promover alterações de comportamentos das pessoas singulares e coletivas e assim promover um crescimento económico sustentável.

description: A indemnização pela “perda de chance” traduz-se numa terceira categoria de interesse contratual, pela qual o particular pode ser ressarcido pela entidade pública adjudicante, no âmbito do procedimento pré-contratual. O ressarcimento do particular pelo interesse contratual positivo e pelo interesse contratual negativo não cobrem, a nosso ver, toda a gama multifacetada de situações originadoras de danos à esfera jurídico-patrimonial do concorrente. A figura da “perda de chance” permite ultrapassar as dificuldades probatórias associadas à teoria da causalidade adequada, do tipo “tudo ou nada”, revestindo ainda uma relevância central na averiguação do quantum indemnizatório. Por conseguinte, consiste num mecanismo de superação das dificuldades no reconhecimento de indemnização ao particular lesado. As questões primaciais que suscitamos são, entre outras, as seguintes: a) Em que circunstâncias estão as entidades adjudicantes vinculadas ao ato de adjudicação e à celebração do contrato? b) Podem as entidades adjudicantes “revogar a decisão de contratar”? c) Sendo a resposta afirmativa, em que casos e quais os direitos dos particulares?; d) Qual o alcance da tutela indemnizatória reconhecida ao particular ilegalmente preterido no âmbito do procedimento pré-contratual?

description: We consider quasi one-dimensional RKKY systems in proximity to an s-wave superconductor. We show that a $2k_F$-peak in the spin susceptibility of the superconductor in the one-dimensional limit supports helical order of localized magnetic moments via RKKY interaction, where $k_F$ is the Fermi wavevector. The magnetic helix is equivalent to a uniform magnetic field and very strong spin-orbit interaction (SOI) with an effective SOI length $1/2k_F$. We find the conditions to establish such a magnetic state in atomic chains and semiconducting nanowires with magnetic atoms or nuclear spins. Generically, these systems are in a topological phase with Majorana fermions. The inherent self-tuning of the helix to $2k_F$ eliminates the need to tune the chemical potential.

description: We present 25 new eclipse times of the white dwarf binary NN Ser taken with the high-speed camera ULTRACAM on the WHT and NTT, the RISE camera on the Liverpool Telescope, and HAWK-I on the VLT to test the two-planet model proposed to explain variations in its eclipse times measured over the last 25 years. The planetary model survives the test with flying colours, correctly predicting a progressive lag in eclipse times of 36 seconds that has set in since 2010 compared to the previous 8 years of precise times. Allowing both orbits to be eccentric, we find orbital periods of 7.9 +/- 0.5 yr and 15.3 +/- 0.3 yr, and masses of 2.3 +/- 0.5 Mjup and 7.3 +/- 0.3 Mjup. We also find dynamically long-lived orbits consistent with the data, associated with 2:1 and 5:2 period ratios. The data scatter by 0.07 seconds relative to the best-fit model, by some margin the most precise of any of the proposed eclipsing compact object planet hosts. Despite the high precision, degeneracy in the orbit fits prevents a significant measurement of a period change of the binary and of N-body effects. Finally, we point out a major flaw with a previous dynamical stability analysis of NN Ser, and by extension, with a number of analyses of similar systems.

description: In a “post-state” era, sub-state political communities face new challenges. Modern constitutionalism resorted to various political and territorial forms to ensure the autonomy of certain social communities; in many cases, uniting different nations under the same State. But the integration of States into transnational political communities had profound implications on the sub-state levels of government. In the European context, it is now widely recognized that the process of integration unleashed centripetal forces. This article revisits the effects of European integration in the internal distribution of powers and examines the novelties introduced by the Lisbon Treaty regarding the position, the powers, and the rights of substate communities in EU Law.

description: Cloud computing represents a major shift in information systems architecture, combining both new deployment models and new business models. Rapid provisioning, elastic scaling, and metered usage are essential characteristics of cloud services, and they require cloud resources with these same characteristics. When cloud services depend on commercial software, the licenses for that software become another resource to be managed by the cloud. This paper examines common licensing models, including open source, and how well they function in a cloud services model. It discusses creative, new, cloud-centric licensing models and how they allow providers to preserve and expand their revenue streams as their partners and customers transition to the cloud. The paper concludes by identifying the next steps to achieve standardized, cloud-friendly licensing models.

Foi, assim, adoptado o acto que tem por objecto permitir o acesso aos documentos das instituições europeias, para que se possa entregar aos cidadãos qualquer tipo de documento, nas condições previstas e dentro dos limites das excepções previstas, o Regulamento (CE) n.º 1049/2001. O regulamento, provocou, como demonstram os relatórios publicados pelas três instituições, um aumento notório e constante dos pedidos de acesso aos documentos, com um decréscimo do número de recusas. Colocou-se na doutrina a questão de saber se, havendo normas específicas previstas em regulamentos sectoriais, o regime geral seria necessário para tais casos. A avaliação final de muitas questões envolvidas está caso a caso na decisão final do Tribunal de Justiça, muito embora a abertura e transparência no decurso dos processos de aplicação das normas da concorrência sejam assumidamente objectivos a prosseguir pela Comissão. Impõe-se uma valoração circunstanciada de cada caso concreto examinado, coordenando o direito de acesso à informação num processo administrativo com os interesses públicos e privados em causa, mantendo um equilíbrio entre o conhecimento processual de determinados dados e a defesa dos interesses maiores.

description: We present high-resolution direct numerical simulation studies of turbulent Rayleigh-Benard convection in a closed cylindrical cell with an aspect ratio of one. The focus of our analysis is on the finest scales of convective turbulence, in particular the statistics of the kinetic energy and thermal dissipation rates in the bulk and the whole cell. The fluctuations of the energy dissipation field can directly be translated into a fluctuating local dissipation scale which is found to develop ever finer fluctuations with increasing Rayleigh number. The range of these scales as well as the probability of high-amplitude dissipation events decreases with increasing Prandtl number. In addition, we examine the joint statistics of the two dissipation fields and the consequences of high-amplitude events. We also have investigated the convergence properties of our spectral element method and have found that both dissipation fields are very sensitive to insufficient resolution. We demonstrate that global transport properties, such as the Nusselt number, and the energy balances are partly insensitive to insufficient resolution and yield correct results even when the dissipation fields are under-resolved. Our present numerical framework is also compared with high-resolution simulations which use a finite difference method. For most of the compared quantities the agreement is found to be satisfactory.

description: O presente contributo aborda diversas questões pertinentes, em matéria tributária, relacionadas com a Administração Local, onde se incluem os Municípios – aos quais damos aqui especial destaque – e as freguesias. Assim, começamos por enquadrar a criação dos tributos e dos seus elementos essenciais, aludindo a alguns dos princípios próprios do poder local, como sejam o da autonomia local, o da subsidiariedade e o da descentralização administrativa, que justificam, de alguma forma, uma certa margem de manobra (ainda que constitucional e legalmente limitada) das autarquias locais no âmbito da tributação. Seguidamente, passamos para a concretização dos poderes tributários locais no âmbito da legislação vigente, com destaque para o Regime Geral das Taxas das Autarquias Locais (RGTAL) e o Regime Financeiro das Autarquias Locais e Entidades Intermunicipais (v.g., 6.ª Lei das Finanças Locais).

description: O Estado angolano decidiu recentemente proceder à reforma do enquadramento legal relativo aos fundos de investimento imobiliário (FII), que já existiam desde 2008. Pretendeu-se a criação de um regime jurídico e fiscal moderno e sofisticado, com vista a captar investimento e, por via disso, criar um efetivo mercado de capitais no sector imobiliário. Neste contexto, procurar-se-á no presente artigo analisar, nas suas diferentes dimensões, o regime jurídico e fiscal dos FII, como patrimónios autónomos sem personalidade jurídica, na jurisdição angolana, incluindo referências à sua natureza jurídica, tipologia, processo constitutivo e documentos relevantes, regras de funcionamento e de avaliação de ativos, estrutura organizacional, responsabilidade civil dos intervenientes, regras de publicidade e informação e ao regime fiscal aplicável. Concluir-se-á com algumas reflexões sobre a sua implementação, as dificuldades conjunturais e estruturais sentidas desde a sua aprovação e propostas de alteração do regime em vigor.

description: As of 2022, Laos operated numerous power plants, primarily hydroelectric, with significant generation capacity. The government aims to strategically expand electricity export revenues over the next two decades, transforming the nation’s energy export potential. By 2050, control of many hydropower plants under concessionary agreements will shift to the government, impacting the energy sector and the entire socio-economic landscape. An energy systems model was developed to analyse these changes. The analysis indicates a reduced reliance on imports and increased export potential. Strategic investments in transmission infrastructure and local industries, such as green hydrogen production, are essential for sustainable growth and energy self-sufficiency.

description: This article looks at research into student learning and university teaching, looking specifically at the differing perspectives and levels of focus typically adopted. The perspectives are those of researchers, students, and teachers, while the differing levels of focus are based on the individual students’ experiences of learning, the classroom contextand teaching-learning environment, and the institutional level and academics’ perceptions of teaching. These differences of perspective and focus are illustrated through three specific ,studies carried out by the authors, and suggest the need to capitalize on the differing perspectives to broaden the understanding of the multifarious influences on student learning

Publisher: name: Review of Business and Legal Sciences / Revista de Ciências Empresariais e Jurídicas
Year: 2018

description: While Corporate Social Responsibility (CSR) and associated reporting has been studied extensively, little research has been done from a longitudinal perspective. This paper explores the presentational changes in CSR disclosures in the annual reports of an electricity company over the period from 1986 to 2017 using themes and methods drawn from extant research. The analysis shows changes are in general reflective of external factors such as legislation, economic crises, CSR frameworks and the organisation’s competitive environment. A more stable level of CSR reporting is apparent since about 2010, and the levels are substantially higher in more recent years

description: We present new photometric data from our Herschel Key Programme, the Dwarf Galaxy Survey (DGS), dedicated to the observation of the gas and dust in 48 low-metallicity environments. They were observed with PACS and SPIRE onboard Herschel at 70,100,160,250,350, and 500 microns. We focus on a systematic comparison of the derived FIR properties (FIR luminosity, dust mass, dust temperature and emissivity index) with more metal-rich galaxies and investigate the detection of a potential submm excess. The data reduction method is adapted for each galaxy to derive the most reliable photometry from the final maps. PACS flux densities are compared with the MIPS 70 and 160 microns bands. We use colour-colour diagrams and modified blackbody fitting procedures to determine the dust properties of the DGS galaxies. We also include galaxies from the Herschel KINGFISH sample, containing more metal-rich environments, totalling 109 galaxies. The location of the DGS galaxies on Herschel colour-colour diagrams highlights the differences in global environments of low-metallicity galaxies. The dust in DGS galaxies is generally warmer than in KINGFISH galaxies (T_DGS~32 K, T_KINGFISH~23 K). The emissivity index, beta, is ~1.7 in the DGS, but metallicity does not make a strong effect on beta. The dust-to-stellar mass ratio is lower in low-metallicity galaxies: M_dust/M_star~0.02% for the DGS vs 0.1% for KINGFISH. Per unit dust mass, dwarf galaxies emit ~6 times more in the FIR than higher metallicity galaxies. Out of the 22 DGS galaxies detected at 500 micron, 41% present an excess in the submm not explained by our dust SED model. The excess mainly appears in lower metallicity galaxies (12+log(O/H) < 8.3), and the strongest excesses are detected in the most metal-poor galaxies. We stress the need for observations longwards of the Herschel wavelengths to detect any submm excess appearing beyond 500 micron.
