description: Com um caráter exploratório, este trabalho tem como objetivo geral estudar a divisão regional do desenvolvimento humano dentro do Estado de Pernambuco, a partir dos dados do Atlas de Desenvolvimento Humano da Fundação João Pinheiro e da aplicação da análise de cluster. Neste sentido, foi possível delinear os principais aspectos regionais do desenvolvimento humano pernambucano. De um modo geral, observou-se que os municípios do interior do Estado encontram-se em pior situação, com destaque negativo para os localizados no sertão. Por outro lado, a Região Metropolitana de Recife pode ser considerada a mesorregião mais desenvolvida do Estado, seguido pelo Vale do São Francisco.---------------------------------------------With an exploratory character, this paper has as general objective to study the regional division of the human development inside of Pernambuco State, starting from data of the Atlas of Human Development of the João Pinheiro Foundation and of the cluster analysis application. Therein, it was possible to describe the main regional aspects of the Pernambuco human development. In general, it was observed that the municipal districts of the interior of the State are in worse situation, standing out negatively those located in the sertão. On the other hand, the Recife Metropolitan Area can be considered the most developed area of the State, followed for the San Francisco Valley.

description: Identification of input data points relevant for the classifier (i.e. serve as the support vector) has recently spurred the interest of researchers for both interpretability as well as dataset debugging. This paper presents an in-depth analysis of the methods which attempt to identify the influence of these data points on the resulting classifier. To quantify the quality of the influence, we curated a set of experiments where we debugged and pruned the dataset based on the influence information obtained from different methods. To do so, we provided the classifier with mislabeled examples that hampered the overall performance. Since the classifier is a combination of both the data and the model, therefore, it is essential to also analyze these influences for the interpretability of deep learning models. Analysis of the results shows that some interpretability methods can detect mislabels better than using a random approach, however, contrary to the claim of these methods, the sample selection based on the training loss showed a superior performance.

description: Nonlinear effects on the early stage of phase ordering are studied using Adomian's decomposition method for the Ginzburg-Landau equation for a nonconserved order parameter. While the long-time regime and the linear behavior at short times of the theory are well understood, the onset of nonlinearities at short times and the breaking of the linear theory at different length scales are less understood. In the Adomian's decomposition method, the solution is systematically calculated in the form of a polynomial expansion for the order parameter, with a time dependence given as a series expansion. The method is very accurate for short times, which allows to incorporate the short-time dynamics of the nonlinear terms in a analytical and controllable way.

description: The design of turbulence optimized stellarators has so far relied on three-dimensional equilibrium codes such as VMEC in order to find the minimum of a given objective function. In this work, we propose a complimentary approach based on the near-axis expansion to compute the geometry parameters of neoclassicaly optimized stellarators used in turbulence studies. As shown here, the near-axis expansion can be a reasonable approximation of the geometric parameters relevant for turbulence and stability simulations of the core of existing optimized stellarator designs. In particular, we examine the geometry coefficients that appear in the gyrokinetic equation, the drift-reduced fluid equations and the ideal ballooning equation. This approach may allow for the development of new stellarator optimization techniques significantly faster than conventional methods.

description: We analytically and numerically study quasinormal frequencies (QNFs) of neutral and charged scalar fields in the charged anti-de Sitter (AdS) black holes and discuss the stability of the black holes in terms of the QNFs. We focus on the range of the mass squared $μ^2$ of the scalar fields for which the Robin boundary condition parametrised by $ζ$ applies at the conformal infinity. We find that if the black hole of radius $r_{+}$ and charge $Q$ is much smaller than the AdS length $\ell$, the instability of the charged scalar field can be understood in terms of superradiance in the reflective boundary condition. Noting that the s-wave normal frequency in the AdS spacetime is a decreasing function of $ζ$, we find that if $|eQ|\ell/r_{+}$ is greater than $(3+\sqrt{9+4μ^2\ell^2})/2$, where $e$ is the charge of the scalar field, the black hole is superradiantly unstable irrespectively of $ζ$. On the other hand, if $|eQ|\ell/r_{+}$ is equal to or smaller than this critical value, the stability crucially depends on $ζ$ and there appears a purely oscillating mode at the onset of the instability. We argue that as a result of the superradiant instability, the scalar field gains charge from the black hole and energy from its ambient electric field, while the black hole gives charge to the scalar field and gains energy from the scalar field but decreases its asymptotic mass parameter.

description: Motivated by a recent detection of 511 keV photons from the center of our Galaxy, we calculate the spectrum of the soft gamma-ray background of the redshifted 511 keV photons from cosmological halos. Annihilation of dark matter particles into electron-positron pairs makes a substantial contribution to the gamma-ray background. Mass of such dark matter particles must be ~ 20 MeV. We include the contribution from the active galactic nuclei and supernovae. The halo substructures may increase the lower bound to >~ 60 MeV.

Para tanto, foi construído um sistema inter-regional de insumo-produto, para o ano de 2002, com sete regiões e 44 setores por região de forma a obter 308 setores no total. Com o intuito de estudar o impacto de alterações no volume de produção dos setores objetivo do estudo (Café Arábica, Café Robusta e Indústria do Café), desenvolveu-se uma série de simulações envolvendo as produções em determinadas regiões. As simulações escolhidas basearam-se em cenários alternativos aos praticados atualmente no Brasil, possibilitando assim observar o impacto que alterações na produção regional podem gerar sobre os Multiplicadores de Produção (Tipo I e II), Multiplicadores de Valor Adicionado (Tipo I e II) e Multiplicadores de Pessoal Ocupado (Tipo I e II).---------------------------------------------This paper intends to analyze the behavior and importance of the sectors of agricultural production and industrialization of coffee for each of the main Brazilian producers (Minas Gerais, Espírito Santo, Sao Paulo, Parana, Bahia and Rondônia) in relation to their economies and in relation to other sectors of the national economy. Building an inter-regional input-output system for the year 2002, with seven regions and 44 sectors per region in order to obtain 308 sectors in total, we study the impact of changes in the volume of production of the sectors objective of the study (Arabica Coffee, Robusta Coffee and Coffee Industry). We developed a series of simulations involving the production in certain regions. The simulations were chosen based on the alternative scenarios currently practiced in Brazil, thus enabling observe the impact that changes in regional production can generate about Production Multipliers (Type I and II), Value Added Multipliers (Type I and II) and Employment Multipliers (Type I and II).
The effect of harmful algae on the summer mortality of juvenile pacific oysters (Crassostrea gigas)
Creators: name: Cassis, David
Publisher: name: University of British Columbia
Year: 2009

description: During the summer of 2001, a mass mortality of early juvenile Pacific oysters, Crassostrea gigas Gmelin, was observed at a farm site in Jervis Inlet, British Columbia. During this episode, several toxin producing and potentially harmful algae were detected within the phytoplankton community, with a bloom of Protoceratium reticulatum (Claparede et Lachmann) Buetschli preceding and including the mortalities. Searching for a cause we examined experimentally the rapid response behaviour of juvenile oysters to various species of microalgae. The behavioural response was a strong rejection, complete closure and feeding cessation when exposed to cultures of P. reticulatum and Alexandrium tamarense (Lebour) Balech. While exclusion in pseudo-feces (Amphidinium carterae Hulburt) and mixed reactions were observed with other species (Heterosigma akashiwo (Hada) Hada ex Sournia, Karenia mikimotoi (Miyake et Kominami ex Oda) Hansen and Moestrup, Pseudo-nitzschia pseudodelicatissima (Hasle) Hasle, and Gonyaulax spinifera Diesing). The juvenile oysters feed well on the controls provided (Dunaliella tertiolecta Butcher, Isochrysis galbana Parke, Phaeodactylum tricornutum Bohlin, and Chaetoceros calcitrans Paulsen). Our study suggests that several of these phytoplanktonic species could have contributed to the oyster mortality in 2001 by causing starvation. The bloom of P. reticulatum was identified as the main probable cause for the die-off. In order to avoid juvenile losses, the phytoplankton composition and the size of the oysters should be considered at the time of introduction to farm sites. This study is one of the first to focus on the qualitative and quantitative responses of early juvenile oysters (+/- 5mm shell length) to various potentially harmful phytoplanktonic species.
Real implications of Quantitative Easing in the euro area: a complex-network perspective

description: The long-lasting socio-economic impact of the global financial crisis has questioned the adequacy of traditional tools in explaining periods of financial distress, as well as the adequacy of the existing policy response. In particular, the effect of complex interconnections among financial institutions on financial stability has been widely recognized. A recent debate focused on the effects of unconventional policies aimed at achieving both price and financial stability. In particular, Quantitative Easing (QE, i.e., the large-scale asset purchase programme conducted by a central bank upon the creation of new money) has been recently implemented by the European Central Bank (ECB). In this context, two questions deserve more attention in the literature. First, to what extent, by injecting liquidity, the QE may alter the bank-firm lending level and stimulate the real economy. Second, to what extent the QE may also alter the pattern of intra-financial exposures among financial actors (including banks, investment funds, insurance corporations, and pension funds) and what are the implications in terms of financial stability. Here, we address these two questions by developing a methodology to map the macro-network of financial exposures among institutional sectors across financial instruments (e.g., equity, bonds, and loans) and we illustrate our approach on recently available data (i.e., data on loans and private and public securities purchased within the QE). We then test the effect of the implementation of ECB's QE on the time evolution of the financial linkages in the macro-network of the euro area, as well as the effect on macroeconomic variables, such as output and prices.

description: A busca de fonte renovável de energia torna-se foco de debates internacionais como fator necessário para se atingir o desenvolvimento sustentável. Assim, esse trabalho tem como objetivo fazer um breve histórico da produção de álcool no Brasil, uma vez que o país possui um histórico relevante nessa área. Em 1975 implementou-se o Programa Nacional do Álcool – Proálcool. Este programa encontra-se dividido em quatro fases distintas, em que se observam muitos pontos que estimularam o crescimento e a estagnação. Atualmente, o Etanol brasileiro demonstra indício de alavancagem ao crescimento do PIB no Brasil. Isso foi possível devido a freqüente alta dos preços do petróleo, a conscientização em nível mundial para redução de poluição, firmado no Protocolo de Kyoto, as características do álcool de ser uma energia renovável, dentre outros. As perspectivas futuras para o Etanol brasileiro são bastante otimistas, pois o consumo interno está aumentando relativamente e vários países já aprovaram a mistura do álcool anidro à gasolina, o que deverá aumentar significativamente as exportações. Assim, o Brasil poderá transformar-se no player mundial do álcool.--------------------------------------------Search for renewable sources of energy has become the focus of international debates as a necessary factor to reach sustainable development. This paper has as objective to make an historical briefing of alcohol production in Brazil, therefore this country possesses relevant historical results in this area. In 1975, the National Program of Alcohol – Proálcool has been implemented. This program is divided in four distinct phases, which it is possible to observe many points that have stimulated growth and stagnation in. Currently, Brazilian Ethanol demonstrates signs of leveraging the growth of the GIP in Brazil. This has been possible because of the frequent elevation of the prices of oil; world-wide awareness for pollution reduction, firmed in the Kyoto Protocol; alcohol characteristics of being a renewable energy, among others. Future perspectives for Brazilian Ethanol are significantly optimistic. Internal consumption is relatively increasing and many countries have already approved the mixture of alcohol anidro to gasoline, which shall significantly increase exportations. Thus, Brazil will be able to become the world-wide player of alcohol.

description: During a winter thunderstorm on November 24, 2017, a downward terrestrial gamma-ray flash took place and triggered photonuclear reactions with atmospheric nitrogen and oxygen nuclei, coincident with a lightning discharge at the Kashiwazaki-Kariwa nuclear power station in Japan. We directly detected neutrons produced by the photonuclear reactions with gadolinium orthosilicate scintillation crystals installed at sea level. Two gadolinium isotopes included in the scintillation crystals, $^{155}$Gd and $^{157}$Gd, have large cross-sections of neutron captures to thermal neutrons such as $^{155}$Gd(n,$γ$)$^{156}$Gd and $^{157}$Gd(n,$γ$)$^{158}$Gd. De-excitation gamma rays from $^{156}$Gd and $^{158}$Gd are self-absorbed in the scintillation crystals, and make spectral-line features which can be distinguished from other non-neutron signals. The neutron burst lasted for $\sim$100~ms, and neutron fluences are estimated to be $>$52 and $>$31~neutrons~cm$^{-2}$ at two observation points inside the power plant. Gadolinium orthosilicate scintillators work as valid detectors for thermal neutrons in lightning.

description: Since its launch INTEGRAL has devoted a significant fraction of its observing time to the Galactic plane region. We present the results of INTEGRAL observations of the inner spiral arms of the Galaxy (Norma, Scutum and Sagittarius) with attention to high mass X-ray binaries. The increased sensitivity of the survey and possibility to detect absorbed sources significantly enlarged our sample of HMXBs in comparison with previous studies. For some absorbed sources we present for the first time high quality broadband (1-100 keV) energy spectra. We confirm pulsations of the X-ray flux of IGR J16358-4726, discovered by CHANDRA, and report discovery of pulsations with a period of $228\pm6$ sec from IGR J16465-4507. We confirm that the Galactic high mass X-ray binary distribution is significantly different from the distribution of low mass X-ray binaries concentrated in the Galactic Center. A large fraction of detected high mass X-ray binaries are absorbed sources.

The environmental impact evaluation was conducted in accordance with the system of environmental impact evaluation of technological innovation agriculture (AMBITEC-AGRO). Results showed that the Environmental Impact Index mean technological innovation has been positive. So the technology, in general terms, contributes to the environment improvement. While in economic aspect the technological innovation contributed to the increase in herd productivity, providing economic gains in the order of R$ 744.58 per hectare.
Nature and origin of the early Jurassic copper (-gold) deposits at Minto and Williams Creek, Carmacks Copper Belt, Western Yukon : subtitle examples of deformed porphyry deposits
Creators: name: Tafti, Reza
Publisher: name: University of British Columbia
Year: 2009

description: The Minto (~9 million tonnes; 1.73% Cu, 0.48 g/t Au, 7.5 g/t Ag) and Williams Creek (Carmacks Copper; ~15.5 million tonnes; 1.01% Cu, 0.42 g/t Au) deposits represent the most significant Cu(-Au) deposits discovered thus far within the Carmacks Copper Belt of western Yukon. The origin of the mineralization is controversial and several very different genetic models have previously been proposed for these deposits, including metamorphosed volcanic massive sulphide, metamorphosed redbed copper, or deformed porphyry-style mineralization. Mineralization consists of disseminations and stringers of chalcopyrite and bornite hosted by variably deformed Early Jurassic plutonic rocks and to a lesser extent strongly metamorphosed supracrustal rocks ("siliceous ore" and "biotite schist/amphibolite") that are interpreted to represent mineralized and deformed metasedimentary wall rocks to the mineralized intrusive phases. Mineralization occurred prior to the ductile deformation that has affected the ore host rocks, which now occur as rafts and screens of variable size within slightly younger, undeformed phases of the Granite Batholith. Lithogeochemical studies of both pre- and post-mineralization intrusive phases at Minto and Williams Creek indicate that they are weakly peraluminous, sub-alkaline, and formed in a continental magmatic arc setting. Mineralized granodioritic gneiss from both deposits and post-mineralization granodiorite at Williams Creek yield U-Pb zircon ages of about 197-198 Ma and massive, post-mineralization intrusive phases yield essentially the same age. Ar-Ar dates for muscovite from selvages developed along late quartz-feldspar-epidote veins at Minto are 182-183 Ma. Al-in-hornblende geobarometry for post-mineralization intrusive phases at Minto and Williams Creek indicate that they were emplaced at a depth of >9 km. Pb and S isotopic studies of both deposits indicate a mainly magmatic source for the contained metals and sulphur. Results of the study indicate that the two deposits are most reasonably interpreted to be Cu(-Au) porphyry deposits that formed during the late stages of Early Jurassic arc activity in the region and were tectonically buried and subsequently deformed and metamorphosed immediately after formation. Cu/Au ratios and field observations indicate extensive supergene mobility of Cu, especially at Williams Creek, that has complicated previous interpretations of the deposits.

description: The possibility of cloning a d-dimensional quantum system without an ancilla is explored, extending on the economical phase-covariant cloning machine found in [Phys. Rev. A {\bf 60}, 2764 (1999)] for qubits. We prove the impossibility of constructing an economical version of the optimal universal cloning machine in any dimension. We also show, using an ansatz on the generic form of cloning machines, that the d-dimensional phase-covariant cloner, which optimally clones all uniform superpositions, can be realized economically only in dimension d=2. The used ansatz is supported by numerical evidence up to d=7. An economical phase-covariant cloner can nevertheless be constructed for d>2, albeit with a lower fidelity than that of the optimal cloner requiring an ancilla. Finally, using again an ansatz on cloning machines, we show that an economical version of the Fourier-covariant cloner, which optimally clones the computational basis and its Fourier transform, is also possible only in dimension d=2.

description: We consider spatially dependent functional data collected under a geostatistics setting, where locations are sampled from a spatial point process. The functional response is the sum of a spatially dependent functional effect and a spatially independent functional nugget effect. Observations on each function are made on discrete time points and contaminated with measurement errors. Under the assumption of spatial stationarity and isotropy, we propose a tensor product spline estimator for the spatio-temporal covariance function. When a coregionalization covariance structure is further assumed, we propose a new functional principal component analysis method that borrows information from neighboring functions. The proposed method also generates nonparametric estimators for the spatial covariance functions, which can be used for functional kriging. Under a unified framework for sparse and dense functional data, infill and increasing domain asymptotic paradigms, we develop the asymptotic convergence rates for the proposed estimators. Advantages of the proposed approach are demonstrated through simulation studies and two real data applications representing sparse and dense functional data, respectively.

Several trends are reported that can constrain theoretical models of dust processing in these systems: i) none of the sources consists of fully pristine dust comparable to that found in the interstellar medium, ii) all sources with a high fraction of crystalline silicates are dominated by large grains, iii) the disks around more massive stars (M >~ 2.5 M_sun, L >~ 60 L_sun) have a higher fraction of crystalline silicates than those around lower mass stars, iv) in the subset of lower mass stars (M

description: O trabalho tem como objetivo apresentar alguns elementos que nortearam as políticas públicas de Segurança Alimentar e Nutricional nos anos desde 1970 até os dias atuais, que permitam discutir o papel de iniciativas de segurança alimentar e nutricional e os impactos no consumo o consumo de alimentos da população brasileira. Foram investigadas as pesquisas de órgãos dos governos que evidenciaram a temática da alimentação e da segurança alimentar e analisados dados relativos à situação de consumo de alimentos. As análises desenvolvidas neste trabalho alertam para a grave situação de insegurança alimentar vivenciada por 40% da população brasileira. As tentativas de enfrentamento desta realidade constituem um marco importante, sobretudo no âmbito da institucionalização da segurança alimentar e as definições conceituais para a formulação de políticas públicas sobre esta temática. Identificou-se que a dimensão qualitativa da segurança alimentar tem sido abordada de forma superficial, como também a prática do autoabastecimento familiar que vem sendo substituído pela vinculação do agricultor ao mercado, o que indica a necessidade de se repensar o modelo agrícola e agrário vigente. ----------------------------------------------------The aim of this study is to present some elements which have guided public policies for Feeding and Nutritional Security since 1970 in order to discuss the role of nutritional security initiatives and the impacts on food consumption by the Brazilian population. It were investigated the surveys by governmental organizations that involved feeding and nutritional security, and it were also analyzed data about food consumption. The analyses carried out in this study warn about the critical situation of feeding insecurity faced by 40% of Brazilians. The strategies to overcome this situation are important, mainly the institutionalization and the consolidation of public policy in terms of feeding security. It was concluded that the qualitative dimension of nutritional security has been superficial, and the practice of family auto supplying has been replaced by the farmer participation in the market. It indicates the necessity of rethinking the existent agricultural model.

description: Recognizing emotions during social interactions has many potential applications with the popularization of low-cost mobile sensors, but a challenge remains with the lack of naturalistic affective interaction data. Most existing emotion datasets do not support studying idiosyncratic emotions arising in the wild as they were collected in constrained environments. Therefore, studying emotions in the context of social interactions requires a novel dataset, and K-EmoCon is such a multimodal dataset with comprehensive annotations of continuous emotions during naturalistic conversations. The dataset contains multimodal measurements, including audiovisual recordings, EEG, and peripheral physiological signals, acquired with off-the-shelf devices from 16 sessions of approximately 10-minute long paired debates on a social issue. Distinct from previous datasets, it includes emotion annotations from all three available perspectives: self, debate partner, and external observers. Raters annotated emotional displays at intervals of every 5 seconds while viewing the debate footage, in terms of arousal-valence and 18 additional categorical emotions. The resulting K-EmoCon is the first publicly available emotion dataset accommodating the multiperspective assessment of emotions during social interactions.

description: Panel data are used in almost all subfields of the agricultural economics profession. Furthermore, many research areas have an important spatial dimension. This article discusses some of the recent contributions made in the evolving theoretical and empirical literature on spatial econometric methods for panel data. We then illustrate some of these tools within a climate change application using a hedonic model of farmland values and panel data. Estimates for the model are provided across a range of nonspatial and spatial estimators, including spatial error and spatial lag models with fixed and random effects extensions. Given the importance of location and extensive use of panel data in many subfields of agricultural economics, these recently developed spatial panel methods hold great potential for applied researchers.

description: In this paper we provide a guide for public key infrastructure designers and administrators when planning for directory services. We concentrate on the LDAP directories and how they can be used to successfully publish PKI information. We analyse their available mechanisms and propose a best practice guide for use in PKI. We then take a look into the German Signature Act and Ordinance and discuss their part as far as directories concerning. Finally, we translate those to the LDAP directories practices.

description: Leveraging biased click data for optimizing learning to rank systems has been a popular approach in information retrieval. Because click data is often noisy and biased, a variety of methods have been proposed to construct unbiased learning to rank (ULTR) algorithms for the learning of unbiased ranking models. Among them, automatic unbiased learning to rank (AutoULTR) algorithms that jointly learn user bias models (i.e., propensity models) with unbiased rankers have received a lot of attention due to their superior performance and low deployment cost in practice. Despite their differences in theories and algorithm design, existing studies on ULTR usually use uni-variate ranking functions to score each document or result independently. On the other hand, recent advances in context-aware learning-to-rank models have shown that multivariate scoring functions, which read multiple documents together and predict their ranking scores jointly, are more powerful than uni-variate ranking functions in ranking tasks with human-annotated relevance labels. Whether such superior performance would hold in ULTR with noisy data, however, is mostly unknown. In this paper, we investigate existing multivariate scoring functions and AutoULTR algorithms in theory and prove that permutation invariance is a crucial factor that determines whether a context-aware learning-to-rank model could be applied to existing AutoULTR framework. Our experiments with synthetic clicks on two large-scale benchmark datasets show that AutoULTR models with permutation-invariant multivariate scoring functions significantly outperform those with uni-variate scoring functions and permutation-variant multivariate scoring functions.

description: These articles provide a discussion of studies presented in a session on spatial econometrics, focusing on the ability of spatial regression models to quantify the magnitude of spatial spillover impacts. Both articles presented argue that a proper modeling of spatial spillovers is required to truly understand the phenomena under study, in one case the impact of climate change on land values (or crop yields) and in the second the role of regional industry composition on regional business establishment growth.

description: We investigate, by experiments and numerical simulations, thermal activation processes of Josephson tunnel junctions in the presence of microwave radiation. When the applied signal resonates with the Josephson plasma frequency oscillations, the switching current may become multi-valued temperature ranges both below and above the the classical to quantum crossover temperature. Switching current distributions are obtained both experimentally and numerically at temperatures both near and far above the quantum crossover temperature. Plots of the switching currents traced as a function of the applied signal frequency show very good agreement with a simple anharmonic theory for Josephson resonance frequency as a function of bias current. Throughout, experimental results and direct numerical simulations of the corresponding thermally driven classical Josephson junction model show very good agreement.
