description: The Wallaby-Zenith Fracture Zone, within the Wharton Basin of the East Indian Ocean, is a geomorphologically complex structure with depths from abyssal to hadal (∼6600 m) with limited published taxonomic data. To fill this knowledge gap, this study describes two new species of scavenging amphipods, Stephonyx sigmacrus sp. nov. (Uristidae) and Civifractura serendipia gen. et sp. nov. (Alicellidae), collected using baited traps from a depth of 4932 m. As identification of deep-sea amphipods is challenged by phenotypic plasticity and convergent evolution, we combined a morphological with a molecular phylogenetic analysis of two mitochondrial (16S rDNA and COI) and two nuclear (Histone 3 and 28S rRNA) regions, where possible (no genetic material was obtainable from S. sigmacrus sp. nov.). The genetic data uncovered cryptic taxonomy and elevated diversity within the non-monophyletic Alicellidae family and provided evidence for establishing a new genus. Additionally, we identified morphological variations from the Tectovalopsis wegeneri description, genetically resolved two previously identified specimens of Diatectonia sp. as T. wegeneri, and identified two new species of Tectovalopsis for future description. These investigations highlight the application of integrative taxonomic approaches and represent a potential model for resolving incongruent morphological and molecular phylogenies for deep-sea amphipods and other specimen-limited taxa.

description: Objetivou-se, neste estudo, mensurar e avaliar os impactos da adoção de estratégias de investimento direto externo (IDE), nas métricas de rentabilidade (ROA, ROE e EVA) e risco (volatilidade) da empresa JBS S.A.. Inicialmente, aplicou-se a metodologia de análise de intervenção para estudar o comportamento das métricas de rentabilidade mediante a adoção de estratégias de investimentos externose, a partir do modelo ajustado, pode-se afirmar que o IDE foi capaz de mudar negativamente o comportamento da rentabilidade da empresa. Posteriormente, modelou-se a volatilidade do retorno das ações para verificar a reação do mercado acionário após o anúncio de IDE da JBS S.A. quando, de maneira geral, os resultados confirmaram a hipótese de impacto do IDE na volatilidade porque, em outras palavras, o anúncio de investimentos externos afetam o comportamento do investidor e, consequentemente, eleva o risco do mercado acionário. O estudo é inovador visto que revela o caráter intervencionista das estratégias de IDE nas métricas de rentabilidade e risco da organização estudada. ----- In this study, we aimed to measure and asses the adopting impacts of strategies of Foreign Direct Investments (FDI) in the metrics of profitability (ROA, ROE and EVA) and risk (volatility) of the company JBS S.A. Firstly, we used the methodology of analysing the intervention for studying the pattern of metrics of profitability by means of adoption of strategies of foreign investments and, from fitted models, we can state that the FDI was able to change negatively the pattern of company profitability. Secondly, we modelled the return volatility of assets for verifying the stock market reaction after the announcement of FDI of JBS S.A. when, in general, results confirmed the hypothesis of FDI impact in the volatility because, in other words, the announcement of foreign investments affects the behaviour of the investor and, consequently, raises the risk of stock market. Therefore, the research is innovative because it reveals the interventionist character of FDI strategies in the metrics of profitability and risk of the company.

description: Objetivou-se identificar e avaliar os fatores que afetam o resultado econômico de propriedades rurais familiares, considerando diferentes níveis de Taxa de Remuneração do Capital (TRC). Para tanto, foram utilizados dados de 29 propriedades da região Oeste de Santa Catarina, obtidos através do Diagnóstico Rural Rápido (DRR), durante os anos agrícolas de 2010, 2011 e 2012, submetidos à Análise de Componentes Principais (ACP) e Análise de Redundância (RDA). As propriedades foram classificadas em três grupos de acordo com a TRC, utilizando-se a Renda Líquida (RL) e a Margem Bruta (MB) como variáveis respostas. Um conjunto de variáveis que refletem a disponibilidade dos fatores de produção, as características das atividades desenvolvidas e os aspectos relacionados à gestão da propriedade foram utilizados como variáveis explicativas. Os resultados indicam que a intensificação das atividades produtivas proporciona a obtenção de maiores taxas de remuneração do capital. O trabalho destaca a importância das práticas de gestão e fornece elementos que subsidiam a definição de estratégias para a melhoria dos resultados econômicos e da sustentabilidade de propriedades rurais familiares. ----- The purpose of this study was to identify and assess the factors that affect the economic result of rural family properties, considering different levels of Rate of Return on Capital (RRC). We used data obtained from 29 properties of Western of the State of Santa Catarina, by means of rapid rural appraisal, during the crop years of 2010, 2011 and 2012, by using principal component analysis and redundancy analysis. Properties were classified into three groups according to RRC, using the net yield, and gross margin as response variables. A set of variables reflecting the availability of factors of production, characteristics of activities developed, and aspect related to properties management were used as explanatory variables. According to results, the intensification of productive activities provides greater rate of return on capital. Therefore, it highlighted here, the importance of management practices, and it provides elements which support the development of strategies for improving economic results, and sustainability of rural family properties.

description: Species are a fundamental unit of biodiversity that are delimited via genetic data and coalescent-based methods with increasing frequency. Despite the widespread use of coalescent-based species delimitation, we do not fully understand the sensitivity of these methods to potential sources of bias and violations of their underlying assumptions. One implicit assumption of coalescent-based species delimitation is that geographic sampling is adequate and representative of genetic variation among populations within the lineage of interest. Yet exhaustive geographic sampling is logistically difficult, if not impossible, for many taxa that span large geographic expanses or occupy remote regions. Here, we examine the impact of geographic sampling on the output of Bayes-factor delimitation with SNAPP, a popular coalescent-based species delimitation pipeline. First, we demonstrate the problematic nature of sparse geographic sampling and isolation by distance for species delimitation using simulated data sets of populations connected by different levels of gene flow. We then examine whether similar trends are present in an empirical dataset of Andesiops mayflies (Ephemeroptera: Baetidae) from a high elevation transect in the Ecuadorian Andes. In both the simulated and empirical analyses, we systematically exclude geographically intermediate sites to quantify the impact of geographic sampling and isolation by distance on coalescent-based species delimitation. We find that removing intermediate sites with genetically admixed individuals incorrectly favors multi-species delimitation scenarios. Oversplitting is especially pronounced when isolation by distance is strong, but exists even when gene flow among neighboring populations is relatively high. These findings highlight the importance of adequate geographic sampling in species delimitation and urge caution in interpreting the output of such methods when species’ distributions are sparsely sampled and in systems characterized by strong patterns of isolation by distance.

description: We have studied the changes in the electronic structure and the superconducting transition temperature T_c of Mg(B_{1-x}C_{x})_{2} alloys as a function of x with 0\leq x\leq 0.3. Our density-functional-based approach uses coherent-potential approximation to describe the effects of disorder, Gaspari-Gyorffy formalism to estimate the electron-phonon matrix elements and Allen-Dynes equation to calculate T_c in these alloys. We find that the changes in the electronic structure of Mg(B_{1-x}C_{x})_{2} alloys, especially near the Fermi energy E_F, come mainly from the outward movement of E_F with increasing x, and the effects of disorder in the B plane are small. In particular, our results show a sharp decline in both B and C p_{x(y)} states for 0.2\leq x\leq 0.3. Our calculated variation in T_{c} of Mg(B_{1-x}C_{x})_{2} alloys is in qualitative agreement with the experiments.

description: A agricultura familiar, assim definida pela Lei 11.326/2006, abrange produtores rurais não homogêneos. Nesse artigo, essa diferenciação é observada através do Índice de Mercantilização – IM (razão entre quantidade vendida/quantidade produzida), o qual é distinto para os agricultores familiares produtores de arroz versus os produtores de feijão. Objetivou-se, neste trabalho,verificar a influência de alguns fatores (como área média, preço médio e volume de crédito) sobre o IM para a cultura do feijão e do arroz, através de um modelo de regressão simples e considerando dados agregados em nível de municípios, para o ano de 2006. Os resultados das regressões mostram que essas três variáveis têm efeitos distintos sobre o IM, segundo a região analisada (Brasil e suas cinco macrorregiões), o que reforça a visão de que há grupos diferentes dentro do que se chama agricultura familiar, o que implica em se avaliar a importância de segmentar a política voltada a esse segmento. ----- The family farming comprises non-homogeneous rural farmers, as established in the 11.326/2006 law. This differentiation was analyzed here by using the mercantilization index (MI) given by the ratio between the sold quantity and the produced quantity. This index is different between family farmers which yield rice and those which yield bean. The purpose of this study was to investigate the influence of some factors, such as mean area, mean price, and credit volume, in the MI for bean and rice crops, by means of simple linear regression model, and by considering data aggregated at the municipality level for the year of 2006. The regressions pattern showed that these three parameters have different effects on the MI in Brazil and in the five Brazilian regions, which strengthens the vision of that there are different groups within the family farming. This inference leads to the need of assessing the importance of the policy focused on this segment.

description: In classical superconductors Cooper-pair formation and phase coherence occur simultaneously as the temperature is lowered below Tc. In high-temperature superconductors (HTSC), on the other hand, the small superfluid density and low associated phase stiffness of the superconducting condensate are expected to lead to a separation of the Cooper-pair formation and the phase-coherence temperatures, especially in underdoped materials [3]. The only real phase transition in this scenario is the 3d-XY phase-ordering transition at Tc [3,4]. In our Letter [2] we showed that Tc in underdoped and optimally doped YBCO is just such a phase-ordering temperature, and then the question naturally arises - where do the Cooper pairs form? The observed 3d-XY scaling of our thermal expansion data over a wide temperature range [2] suggests that pairing occurs at temperatures considerably above Tc, and it thus appeared quite natural for us to associate the opening of the pseudogap at T*.

description: Motion blurry images challenge many computer vision algorithms, e.g, feature detection, motion estimation, or object recognition. Deep convolutional neural networks are state-of-the-art for image deblurring. However, obtaining training data with corresponding sharp and blurry image pairs can be difficult. In this paper, we present a differentiable reblur model for self-supervised motion deblurring, which enables the network to learn from real-world blurry image sequences without relying on sharp images for supervision. Our key insight is that motion cues obtained from consecutive images yield sufficient information to inform the deblurring task. We therefore formulate deblurring as an inverse rendering problem, taking into account the physical image formation process: we first predict two deblurred images from which we estimate the corresponding optical flow. Using these predictions, we re-render the blurred images and minimize the difference with respect to the original blurry inputs. We use both synthetic and real dataset for experimental evaluations. Our experiments demonstrate that self-supervised single image deblurring is really feasible and leads to visually compelling results.

description: Objetivou-se, neste estudo, caracterizar a demanda do etanol no mercado brasileiro de combustíveis, considerando os elementos setoriais econômicos e mercadológicos, no tocante à evolução, desafios e novos cenários desse setor. O estudo foi conduzido por meio de uma metodologia exploratória e documental, com uma abordagem analítica qualitativa, indutiva e interpretativa, orientada em um processo cíclico e concomitante entre a literatura e os dados do mercado levantados. O objeto principal de investigação foi a compreensão do mercado do etanol em seu surgimento no Brasil via Proálcool (Programa Nacional do Álcool), bem como, a sua ascensão e queda, os desafios e novos cenários que surgiram a partir do veículo Flex Fuel. Foram encontradas evidências que demonstram que a demanda de combustíveis possibilitou condições de mutação de mercado em variados momentos, desde seu surgimento até o presente, que se iniciou com as pressões econômicas decorrentes da volatilidade dos preços do petróleo até a inserção da tecnologia Flex Fuel, que redesenhou o cenário do mercado do etanol. ----- The aim of this study is characterize the demand for ethanol in the Brazilian fuel market, considering the sectoral elements (economy and market), regarding to the evolution, challenges and new scenarios of the ethanol market. The study was conducted by means of an exploratory methodology, with an analytical approach qualitative, inductive and interpretative, oriented in a cyclic and concomitant process among the literature raised and the data collected from the fuel market. The main object of investigation was the comprehension of the ethanol market in Brazil across the Proálcool (National Program of Alcohol), as well as, its rise and fall, challenges and new scenarios that emerged from the flex fuel vehicle. We found evidences that demonstrate that the fuel demand allowed mutation conditions in the market at various times, since its inception to the present, which began with the economic pressures arising from the volatility of oil prices till the inclusion of flex fuel technology, which redesigned the backdrop of the ethanol market.

description: Experimental results of inclusive hard-process cross sections in heavy-ion collisions conventionally lean on a normalization computed from Glauber models where the inelastic nucleon-nucleon cross section $σ_{\rm nn}^{\rm inel}$ -- a crucial input parameter -- is simply taken from proton-proton measurements. In this letter, using the computed electro-weak boson production cross sections in lead-lead collisions as a benchmark, we determine $σ_{\rm nn}^{\rm inel}$ from the recent ATLAS data. We find a significantly suppressed $σ_{\rm nn}^{\rm inel}$ relative to what is usually assumed, show the consequences for the centrality dependence of the cross sections, and address the phenomenon in an eikonal minijet model with nuclear shadowing.

description: We show that the Iancu-Mueller factorization has a simple interpretation in the Reggeon - like technique based on the BFKL Pomeron. The formula for calculating the high energy asymptotic behaviour for the colour dipole-dipole amplitude is proposed which suggests a procedure to calculate this amplitude through the solution to the Balitsky-Kovchegov non-linear equation. We confirm the Iancu - Mueller result that a specific set of enhanced diagrams is responsible for the high energy behaviour for fixed QCD coupling. However, it is argued that in the case of running QCD coupling, this asymptotic behaviour originates from the Balitsky-Kovchegov non-linear equation. A new solution to the non-linear equation is found which leads to a different asymptotic behaviour of the scattering amplitude even for fixed QCD coupling..

description: We show that exactly marginal operators of Supersymmetric Conformal Field Theories (SCFTs) with four supercharges cannot obtain a vacuum expectation value at a generic point on the conformal manifold. Exactly marginal operators are therefore nilpotent in the chiral ring. This allows us to associate an integer to the conformal manifold, which we call the nilpotency index of the conformal manifold. We discuss several examples in diverse dimensions where we demonstrate these facts and compute the nilpotency index.

title: Women as mothers: Changing role perceptions an intergenerational study
Creators: name: Ulanowsky, Carole Elizabeth
Publisher: name: The Open University

description: Significant change in the positioning of motherhood in women's lives is starkly revealed by comparing the 1970s and 1990s. Though barely a generation apart, these two decades afforded socio-cultural settings of distinctive contrast. In the 1970s, for example, mothers felt constrained to put their working lives on hold and focus their energies on raising children. In the intervening years, however, feminist discourse, in parallel with economic and demographic change, served to strengthen the value of paid work above unpaid endeavour. By the 1990s, an increasing number of women would fit motherhood into the interstices of their working lives. These several considerations led to a broad theoretical enquiry, including the issues of gender, work, and the needs of mothers and their infant children. The focus has been on researching perceptions of motherhood among women representative of occupational groups 1, 2 and 3 only (SOC, 2000). High functioning women experience a particular tension between motherhood and other life roles, as the literature testifies. The aim of uncovering the essence of personal experience suggested a qualitative approach to data collection, within a feminist framework.

description: We report the Chandra discovery of an X-ray jet associated with the redshift 4.3 radio-loud quasar GB 1508+5714. The jet X-ray emission peaks ~2 arcsec to the South-West of the quasar core. We present archival HST WFPC2 data of the quasar field which shows no optical emission at the location of the X-ray jet. We discuss possible emission mechanisms and give constraints to the magnetic field and energy densities for synchrotron radiation or for Compton scattering of the Cosmic Microwave Background radiation as the jet X-ray emission process.

description: Designing reconfigurable metasurfaces that can dynamically control scattered electromagnetic waves and work in the near-infrared (NIR) and optical regimes remains a challenging task, which is hindered by the static material property and fixed structures. Phase change materials (PCMs) can provide high contrast optical refractive indexes at high frequencies between amorphous and crystal states, therefore are promising as feasible materials for reconfigurable metasurfaces. Here, we propose a hybrid metasurface that can arbitrarily modulate the complex amplitude of incident light with uniform amplitude and full $2π$ phase coverage by utilizing composite concentric rings (CCRs) with different ratios of gold and PCMs. Our designed metasurface possesses a bi-functionality that is capable of splitting beams or generating vortex beams by thermal switching between metal and semiconductor states of vanadium oxide (VO2), respectively. It can be easily integrated into low loss photonic circuits with an ultra-small footprint. Our metadevice serves as a novel paradigm for active control of beams, which may open new opportunities for signal processing, memory storage, holography, and anti-counterfeiting.

description: Using the Korringa-Kohn-Rostoker coherent-potential approximation in the atomic-sphere approximation (KKR-ASA CPA) we have studied the changes in the electronic structure and the superconducting transition temperature T_{c} in Nb_{1-x}B_{2} alloys as a function of x. We find that the variation in the electronic structure of Nb_{1-x}B_{2} alloys as a function of x is consistent with the rigid-band model. However, the variation of T_{c}, obtained using the Allen-Dynes equation within the Gaspari-Gyorffy formalism to estimate the electron-phonon matrix elements, does not follow the expected trend. We associate this disagreement to the use of a constant ω_{rms} in the Allen-Dynes equation over the whole range of vacancy concentration, thereby indicating the importance of lattice dynamical effects in these systems.

description: The discovery and characteristics of transneptunian binaries are reviewed. In the 20 years since their first discovery, a wealth of detail has emerged including the frequency of binaries in different populations, their relative sizes and separations, and colors. Taken globally, these properties give strong clues to the origin and evolution of the populations where these binaries are found. In the last ten years and increasing number of binary orbits have been determined which yields a new trove of information on their masses and densities as well as details of their orbits including inclination, eccentricity and the timing of mutual events. In 2018, the study of transneptunian binaries remains one of the most active areas of progress in understanding the Solar System beyond Neptune.

description: The article clarifies the policy of the Soviet state and party bodies on procedures for registering childbirth and marriage in the post-war period in the Moldavian SSR. As a result of the implementation of the communist ideology and Soviet legislation in the MSSR, these procedures have undergone a number of changes. The transformations promoted at the administrative level through the adoption of normative acts resulted in the separation of the Church from the legal procedure for the registration of civil status documents. Also, some of the clergy’s freedom to serve religious services has been restricted, and the Church has been removed to the periphery of society by motivating it to be an institution that promotes vices, archaic and dangerous to the Soviet society customs and rituals. Atheist propaganda aimed at creating a negative image of the Church, closing the churches, and gradually reducing the number of believers. At the same time, in order to substitute religious rituals, civil ceremonies were created, which took on some elements of tradition to be infiltrated into family habits, labeled as new. In spite of the anti-religious measures and pressures on society, a significant proportion of the population in the MSSR in the post-war period continued to maintain their faith and to practice the religious ceremonies of the church, alongside with the civil compulsory ones, imposed by laws and administrative methods.

description: The BL Lac object 4FGLJ0955.1+3551 has been suggested as a possible source of ultra energetic neutrinos detected by the Icecube observatory. The target was observed in January 2020 at the Large Binocular Telescope. Our spectroscopy (4100-8500 Ang) yields a firm redshift z = 0.557 as deduced by the absorption lines of the host galaxy. The upper limit of the minimum equivalent width on emission lines is 0.3 Ang. From the source image we are able to resolve the host galaxy for which we measure an absolute magnitude M(R) = -22.9 and Re = 8 kpc, that is values which are typical of the host galaxies of BL Lacs.

description: In real paramagnets, there is always a subtle many-body contribution to the system's energy, which can be regarded as a small effective local magnetic field $B_{loc}$. Usually, it is neglected, since it is very small when compared with thermal fluctuations and/or external magnetic fields $B$. Nevertheless, as both the temperature $T \rightarrow$ 0K and $B \rightarrow$ 0T, such many-body contributions become ubiquitous. Here, employing the magnetic Grüneisen parameter $Γ_{mag}$ and entropy arguments, we report on the pivotal role played by the mutual interactions in the regime of ultra-low-$T$ and vanishing $B$. Our key results are: $i$) absence of a genuine zero-field quantum phase transition due to the presence of $B_{loc}$; $ii$) connection between the canonical definition of temperature and $Γ_{mag}$; and $iii$) possibility of performing adiabatic magnetization by only manipulating the mutual interactions. Our findings unveil unprecedented aspects emerging from the mutual interactions.

description: Electrostatic analyzers of different designs have been used since the earliest days of the space age, beginning with the very earliest solar wind measurements made by Mariner 2 en route to Venus in 1962. The Parker Solar Probe (PSP) mission, NASA's first dedicated mission to study the innermost reaches of the heliosphere, makes its thermal plasma measurements using a suite of instruments called the Solar Wind Electrons, Alphas, and Protons (SWEAP) investigation. SWEAP's electron Parker Solar Probe Analyzer (SPAN-E) instruments are a pair of top-hat electrostatic analyzers on PSP that are capable of measuring the electron distribution function in the solar wind from 2 eV to 30 keV. For the first time, in-situ measurements of thermal electrons provided by SPAN-E will help reveal the heating and acceleration mechanisms driving the evolution of the solar wind at the points of acceleration and heating, closer than ever before to the Sun. This paper details the design of the SPAN-E sensors and their operation, data formats, and measurement caveats from Parker Solar Probe's first two close encounters with the Sun.

On Statistical Query Sampling and NMR Quantum Computing

description: We introduce a ``Statistical Query Sampling'' model, in which the goal of an algorithm is to produce an element in a hidden set $Ssubseteqbit^n$ with reasonable probability. The algorithm gains information about $S$ through oracle calls (statistical queries), where the algorithm submits a query function $g(cdot)$ and receives an approximation to $Pr_{x in S}[g(x)=1]$. We show how this model is related to NMR quantum computing, in which only statistical properties of an ensemble of quantum systems can be measured, and in particular to the question of whether one can translate standard quantum algorithms to the NMR setting without putting all of their classical post-processing into the quantum system. Using Fourier analysis techniques developed in the related context of {em statistical query learning}, we prove a number of lower bounds (both information-theoretic and cryptographic) on the ability of algorithms to produces an $xin S$, even when the set $S$ is fairly simple. These lower bounds point out a difficulty in efficiently applying NMR quantum computing to algorithms such as Shor's and Simon's algorithm that involve significant classical post-processing. We also explicitly relate the notion of statistical query sampling to that of statistical query learning.
