description: We show that (massive) D=10 type IIA supergravity possesses a hidden rigid SO(9,9) symmetry and a hidden local SO(9) x SO(9) symmetry upon dimensional reduction to one (time-like) dimension. We explicitly construct the associated locally supersymmetric Lagrangian in one dimension, and show that its bosonic sector, including the mass term, can be equivalently described by a truncation of an E10/K(E10) non-linear sigma-model to the level \ell<=2 sector in a decomposition of E10 under its so(9,9) subalgebra. This decomposition is presented up to level 10, and the even and odd level sectors are identified tentatively with the Neveu--Schwarz and Ramond sectors, respectively. Further truncation to the level \ell=0 sector yields a model related to the reduction of D=10 type I supergravity. The hyperbolic Kac--Moody algebra DE10, associated to the latter, is shown to be a proper subalgebra of E10, in accord with the embedding of type I into type IIA supergravity. The corresponding decomposition of DE10 under so(9,9) is presented up to level 5.

description: O presente trabalho investigou, com as metodologias de causalidade segundo Granger e VECM, a relação entre o PIB Agropecuário brasileiro e as variáveis consumo de energia do setor, maquinário agrícola, rebanho bovino e produção de grãos no período de 1970 a 2005. O consumo de energia foi enfatizando devido à agropecuária ser produtora e consumidora desta. Os resultados apontam uma grande relação, no curto prazo, entre o PIB e o consumo de energia. Quando se considera o conjunto das variáveis encontrou-se evidência de causalidade segundo Granger, evidenciando a importância das variáveis selecionadas como variáveis explicativas do PIB agropecuário. --------------This study used Granger causality and VECM methodologies, to investigate the relationship between the Brazilian agricultural GDP (Gross Domestic Product) and energy consumption in the sector, agricultural machinery, bovine cattle and grain yield from 1970 to 2005. Energy consumption was emphasized due to the agriculture being both, producer and consumer of it. Results indicate a great relationship, in the short run, between GDP and energy consumption. When considering all the variables it was found evidence of causality according to Granger, highlighting the importance of the selected variables as explanatories of agricultural GDP.

description: Este artigo tem por objetivo avaliar o impacto das mudanças climáticas sobre a agricultura brasileira tanto em termos da rentabilidade agrícola quanto do preço da terra. Para este fim, são estimados dois modelos econométricos: o modelo de efeitos fixos, segundo a metodologia desenvolvida por Deschênes e Greenstone (2007), e o modelo de preços hedônicos proposto por Mendelsohn et al. (1994). Ambos os modelos são estimados utilizando dados de painel para os municípios brasileiros no período de 1970-1995. Os resultados das simulações sugerem que o impacto das mudanças climáticas no setor agrícola brasileiro será relativamente modesto no médio prazo. Contudo, estes impactos tendem a tornar-se significativamente mais severos no longo prazo--------------------------This paper aims at estimating the effects of climate change on the Brazilian agriculture both in terms of agricultural profitability and land values. To accomplish this task, we estimate two econometric models: the fixed-effects model proposed by Deschênes and Greenstone (2007) and the hedonic model proposed by Mendelsohn et al. (1994). Both models are estimated for a panel of municipalities covering the period 1970-1995. Simulation results suggest that the overall impact of climate change will be quite modest for the Brazilian agriculture in the medium term, but these impacts are considerably more severe in the long term.
On attempting to automate the identification of mixed dipole modes for subgiant stars
Creators: name: Appourchaux, T.
Publisher: name: arXiv
Year: 2020
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The existence of mixed modes in stars is a marker of stellar evolution. Their detection serves for a better determination of stellar age. The goal of this paper is to identify the dipole modes in an automatic manner without human intervention. I use the power spectra obtained by the Kepler mission for the application of the method. I compute asymptotic dipole mode frequencies as a function of coupling factor and dipole period spacing, and other parameters. For each star, I collapse the power in an echelle diagramme aligned onto the monopole and dipole mixed modes. The power at the null frequency is used as a figure of merit. Using a genetic algorithm, I then optimise the figure of merit by adjusting the location of the dipole frequencies in the power spectrum}. Using published frequencies, I compare the asymptotic dipole mode frequencies with published frequencies. I also used published frequencies for deriving coupling factor and dipole period spacing using a non-linear least squares fit. I use Monte-Carlo simulations of the non-linear least square fit for deriving error bars for each parameters. From the 44 subgiants studied, the automatic identification allows to retrieve within 3 $μ$Hz at least 80\% of the modes for 32 stars, and within 6 $μ$Hz at least 90% of the modes for 37 stars. The optimised and fitted gravity-mode period spacing and coupling factor agree with previous measurements. Random errors for the mixed-mode parameters deduced from Monte-Carlo simulation are about 30-50 times smaller than previously determined errors, which are in fact systematic errors. The period spacing and coupling factors of mixed modes in subgiants are confirmed. The current automated procedure will need to be improved using a more accurate asymptotic model and/or proper statistical tests.

description: Houve um importante crescimento do número de assentamentos rurais após 1994 e diversos estudos já comprovaram que a quantidade e a qualidade dos projetos não estariam associadas. Há muita pobreza entre os assentados rurais, mas muitos assentamentos se destacam neste cenário de pobreza, conseguindo melhores rendas comparativamente à média geral. Este estudo analisa quais são os fatores mais importantes para esta diferenciação entre os assentamentos rurais mato-grossenses. Utilizaram-se dados do Censo da Reforma Agrária de 2002 com técnicas de análise envoltória de dados (DEA) para se obter a fronteira eficiente, e assim detectar o que causa maior eficiência ou menor ineficiência entre os projetos estudados. Entre as variáveis analisadas estavam infra-estrutura social e de habitação, isolamento econômico, crédito rural, área, entre outras, concluindo-se que quanto maior a distância dos centros urbanos, o tamanho do lote, a utilização de energia elétrica e a disponibilidade de mão-de-obra maior é a ineficiência. O estudo contribui para a literatura ao aplicar o método para este tipo de análise, com uso de variáveis categóricas em DEA e ainda oferecendo resultados aplicados para o estudo regional.---------------------------There was an important growth in the number of rural settlements after 1994 and some works have already shown that quantity and quality of those projects were notassociated. There is huge poverty among rural settled but many projects show up in this poverty picture achieving better income relative to general average. This work analyses what are the most important factors explaining this difference among rural settlements of Mato Grosso, using data from the Agrarian Reform Census of 2002 and data envelopment analysis (DEA) techniques to obtain the efficient frontier and so, detect what has caused higher efficiency or lower inefficiency among studied projects. Among others, some of the variables were social and housing infra-structure, economic isolation, rural credit and area, concluding that greater distance from urban centers, larger farms, use of electricity and greater labor availability increases inefficiency. The study contributes to the literature using this technique to this type of analysis, using categorical variables in DEA and also applied results to regional studies.

description: Материалы статьи посвящены теоретическому и экспериментальному определению производительности винтов грануляторов комбикормов. Приведены математические модели производительности винтов грануляторов в общем виде. Раскрыто влияние интенсивности изменения высоты канала винта на его производительность. Показано, что одним из путей повышения эффективности животноводства является применение полнорационных кормовых гранул с содержанием белково-витаминных трав, а использование для приготовления таких гранул винтовых грануляторов с изменяемыми по длине винта параметрами канала позволяет повысить эффективность кормопроизводства. Для грануляторов с винтами, параметры которых изменяются по их длине, путем решения уравнения Навье-Стокса для условий ньютоновской жидкости, было получено уравнение их производительности в общем виде. Полученная зависимость позволяет оценить влияние на производительность винтового гранулятора как конструкционнорежимных параметров рабочих органов, так и физико-механических свойств кормового сырья. В качестве интегрального показателя физикомеханических свойств кормосмеси при теоретических исследованиях был использован показатель вязкости. Проведенные с помощью ротационного вискозиметра лабораторные исследования позволили установить влияние факторов влажности и содержания сена в кормосмеси на ее вязкость. С целью проверки адекватности полученной математической модели производительности винта были проведены экспериментальные исследования, в ходе которых было определено влияние на производительность гранулятора влажности кормосмеси, диаметра отверстий матрицы, числа оборотов винта гранулятора и коэффициента изменения глубины канала винта по длине винта. Совместный анализ полученных выражений позволил установить, что функция производительности имеет оптимум как для теоретический, так и для эмпирической зависимостей, а общий характер функций свидетельствует об адекватности результатов теоретических исследований. Путем анализа функции производительности на экстремумы было получено выражение оптимальной интенсивности изменения глубины канала винта по критерию производительности гранулятора

Os dados referentes aos preços de venda de pêssegos e às características de qualidade dos frutos (como tamanho, tipos de variedade e categoria) foram obtidos a partir de cortes seccionais no tempo. O Modelo de Preços Hedônicos foi proposto para valoração das características ao longo do elo considerado. Os resultados obtidos permitiram identificar potenciais ganhos na cadeia a partir do aprimoramento de atributos de qualidade dessa fruta.-------------------An econometric model were developed to estimate the implicit prices for selected quality attributes of fresh peaches commercialized in the state of Sao Paulo from producer stage. Such estimation is conducted for this stage of the distribution chain, namely, producer sales. Data on the price and quality attributes (such as size, varieties and categories) of fresh peaches were obtained from cross-sectional. The estimation of Hedonic Prices is proposed as a method to evaluate post-harvest price variations from producer sales. The results obtained allowed us to identify the gains accrued in this stage, deriving from the improvement in the product quality attributes.

description: The rate-limiting step of some enzymatic reactions is a physical step, i.e. diffusion. The efficiency of such reactions can be improved through an increase in the arrival rate of the substrate molecules, e.g. by a directed passage of substrate (ligand) to active site after its random encounter with the enzyme surface. Herein, we introduce a cellular automata model simulating the ligand passage over the protein surface to its destined active site. The system is simulated using the lattice gas automata with probabilistic transition rules. Different distributions of amino acids over the protein surface are examined. For each distribution, the hydration pattern is achieved and the mean number of iteration steps needed for the ligand to arrive at the active site calculated. Comparison of results indicates that the rate at which ligand arrives at the active site is clearly affected by the distribution of amino acids outside the active side. Such a process can facilitate the ligand diffusion towards the active site thereby enhancing the efficiency of the enzyme action.

description: Scalability and performance of current flash memories can be improved substantially by replacing the floating poly-Si gate by a layer of Si dots. This multi-dot layer can be fabricated CMOS-compatibly in very thin gate oxide by ion beam synthesis (IBS). Here, we present both experimental and theoretical studies on IBS of multi-dot layers consisting of Si nanocrystals (NCs). The NCs are produced by ultra low energy Si ion implantation, which causes a high Si supersaturation in the shallow implantation region. During post-implantation annealing, this supersaturation leads to phase separation of the excess Si from the SiO2. Till now, the study of this phase separation process suffered from the weak Z contrast between Si and SiO2 in Transmission Electron Microscopy (TEM). Here, this imaging problem is resolved by mapping Si plasmon losses with a Scanning Transmission Electron Microscopy equipped with a parallel Electron Energy Loss Spectroscopy system (PEELS-STEM). Additionally, kinetic lattice Monte Carlo simulations of Si phase separation have been performed and compared with the experimental Si plasmon maps. It has been predicted theoretically that the morphology of the multi-dot Si floating-gate changes with increasing ion fluence from isolated, spherical NCs to percolated spinodal Si pattern. These patterns agree remarkably with PEELS-STEM images. However, the predicted fluence for spinodal patterns is lower than the experimental one. Because oxidants of the ambient atmosphere penetrate into the as-implanted SiO2, a substantial fraction of the implanted Si might be lost due to oxidation.

Bounds on the elastic threshold for problems of dissipative strain-gradient plasticity

Subjects: subject: Classical Physics (physics.class-ph)

description: This work is concerned with the purely dissipative version of a well-established model of rate-independent strain-gradient plasticity. In the conventional theory of plasticity the approach to determining plastic flow is local, and based on the stress distribution in the body. For the dissipative problem of strain-gradient plasticity such an approach is not valid as the yield function depends on microstresses that are not known in the elastic region. Instead, yield and plastic flow must be considered at the global level. This work addresses the problem of determining the elastic threshold by formulating primal and dual versions of the global problem and, motivated by techniques used in limit analysis for perfect plasticity, establishing conditions for lower and upper bounds to the threshold. The general approach is applied to two examples: of a plate under plane stress, and subjected to a prescribed displacement; and of a bar subjected to torsion.

description: With the progression of the climate crisis, countries aim to achieve energy transitions by increasing their renewable energy shares. Onshore wind power plays a central role in facilitating this transition, especially in Germany, one of the pioneers of transitioning the electricity sector. Achieving transition targets and securing the supply are inextricably linked to the availability of land for and installation of renewable energy infrastructure. Challenges have increased to create space for wind power in Germany, i.e., allocate land for wind turbines. Bottlenecks could be attributed to mismatches in the underlying polycentric governance framework. Polycentric governance is a complex governance form with multiple yet independent decision-making centres. This article contributes to the question of how appropriate space for wind power can be identified. It analyses how governance processes evolve in a polycentric setting and with what consequences. In applying polycentricity, it assesses why it has become complex to create space for onshore wind power. Methods include a single-case study design and the polycentric lens as an analytical frame. Results demonstrate that wind power governance is a complex, multi-element endeavour with strengths and weaknesses. These can be attributed to six systemic issues in polycentric governance: structural inequities, incremental bias, high complexity, deep structural fissures, coordination failures, and lack of normative clarity. The analysis shows how polycentric governance can substantially support finding locations for wind power, yet this needs to be addressed deliberately. This covers relevant access points, e.g. from private, institutionalised or public actors and other channels of mobilisation.

description: Muscle weakness can cause devastating impacts on the gait pattern. Thus, research on devices and elements, capable to assist walking movement is of high importance. This thesis intends to investigate the effects of passive path spring implementation parallel to m. recuts femoris for persons suffering from m. rectus femoris weakness. The study is limited to the pre-swing, initial and mid-swing phases of gait and focusses on the three muscles m. rectus femoris, m. vastus intermedius and m. biceps femoris caput longum. Five main muscle parameters are selected for investigation: force, power, normalized fiber length, normalized fiber velocity and induced femur acceleration. Results show that the spring exhibits a positive effect on force and power of m. vastus intermedius but shows a comparable negative effect in force and power of m. biceps femoris caput longum. Furthermore, the spring affects the induced femur accelerations of all considered muscles in a negative way. The study is performed using the simulation software OpenSim

Diante dessa situação, essa pesquisa objetivou estudar os problemas e conflitos mais freqüentes relacionados à água nos rios do Médio São Francisco, em Minas Gerais, especificamente nos rios Verde Grande, Riachão e Jequitaí, verificando em quais situações essas questões culminam na formalização de Comitês de Bacias Hidrográficas e em que medida estes conseguem enfrentar tais questões. Foram identificados vários problemas que contribuem para a escassez de água nos rios pesquisados. Tais problemas, em sua maioria, são comuns aos três rios, com destaque para a derrubada de mata nativa. Os conflitos mais freqüentes são aqueles envolvendo, de um lado, médios e grandes produtores rurais, que utilizam sistemas de irrigação que consomem muita água, e de outro lado, os pequenos produtores e a comunidade, para quem resta pouca água. Evidenciou-se que os Comitês do Verde Grande e do Jequitaí/Pacuí não têm conseguido resolver os conflitos. Dentre as dificuldades existentes para a atuação dos mesmos, destacam-se a falta de uma estrutura administrativa visando o gerenciamento e a falta de participação popular.------------------This study has the waters as a theme managing the use of water, which have become increasingly scarce. Such shortage ends up triggering conflicts between different users. Facing such situation, this research aimed to study the problems and more frequent conflicts related to the water in the rivers of Médio São Francisco, in Minas Gerais, specifically the rivers Verde Grande, Riachão and Jequitaí, checking in which situations those issues culminate in the formation of Water Basin Committees, and in what extent they can tackle such issues. Several problems that contribute to the shortage of water in rivers searched were identified. Such problems, in the most part are common to the three rivers, standing out the overthrow of native forest. The most frequent conflicts are those involving, on the one hand, medium and large farmers, who use irrigation systems that consume much water, and on the other hand, the small producers and the community, for whom just little water is left. It was evidenced that the Committees of Verde Grande and Jequitaí / Pacuí have not managed to solve conflicts. Among the difficulties for their action, there is in the Committees the lack of an administrative structure for the management and the lack of popular participation.

We give two methods for exactly calculating the fringe visibility in these models, one proceeding directly from the equation of motion for the expectation of the density matrix, and the other proceeding from solving a linear stochastic unravelling of this equation. We also give details of the calculation that identifies the stochasticity parameter implied by the small displacement Taylor expansion of the CSL model density matrix equation. The implications of the two results are briefly discussed. Two pedagogical appendices review mathematical apparatus needed for the calculations.

description: Objectives: Multiple reasons for suboptimal treatment of breakthrough cancer pain (BTcP) have been reported in the literature. We aimed to ascertain the perception of physicians on the potential inappropriate use and prescription of rapid-onset opioids (ROOs) for breakthrough cancer pain (BTcP) and the causes thereof. Methods: Observational study based on an online survey addressed to doctors from different specialties (radiation oncology, medical oncology, anesthesia, palliative care and general practitioners) with experience in the management of BTcP in the Spanish public health setting. Results: A total of 114 eligible specialists mainly from radiation oncology (37.7%), medical oncology (24.6%) and pain units (18.4%) participated in the study. Most agreed on important aspects of BTcP management, such as their preference for ROOs or the need for early follow-up after treatment initiation. However, their answers revealed a lack of standardization of BTcP diagnosis. Half of respondents believed that their BTcP patients might misuse ROOs. Physicians polled believed that lack of training in pain management (71.9%) and inadequate BTcP diagnosis and evaluation (66.7%) were the greatest obstacles for prescribing opioids. Specialists also thought that they do not provide the necessary information to patients (51.8%) and caregivers (57.9%) to guarantee the correct use of these drugs. Conclusions: These results are of utmost importance as they highlight the need to increase physicians’ awareness of BTcP and its management and the need to improve communication with patients and their caregivers. Our findings also indicate the need for future research on the possible misuse of opioids in BTcP patients and its causes.

description: Based on discrete element method simulations, we propose a new form of the constitution equation for granular flows independent of packing fraction. Rescaling the stress ratio $μ$ by a power of dimensionless temperature $Θ$ makes the data from a wide set of flow geometries collapse to a master curve depending only on the inertial number $I$. The basic power-law structure appears robust to varying particle properties (e.g. surface friction) in both 2D and 3D systems. We show how this rheology fits and extends frameworks such as kinetic theory and the Nonlocal Granular Fluidity model.

An Ab Initio Approach to the Solar Coronal Heating Problem

description: We present an ab initio approach to the solar coronal heating problem by modelling a small part of the solar corona in a computational box using a 3D MHD code including realistic physics. The observed solar granular velocity pattern and its amplitude and vorticity power spectra, as reproduced by a weighted Voronoi tessellation method, are used as a boundary condition that generates a Poynting flux in the presence of a magnetic field. The initial magnetic field is a potential extrapolation of a SOHO/MDI high resolution magnetogram, and a standard stratified atmosphere is used as a thermal initial condition. Except for the chromospheric temperature structure, which is kept fixed, the initial conditions are quickly forgotten because the included Spitzer conductivity and radiative cooling function have typical timescales much shorter than the time span of the simulation. After a short initial start up period, the magnetic field is able to dissipate 3-4 10^6 ergs cm^{-2} s^{-1} in a highly intermittent corona, maintaining an average temperature of $\sim 10^6$ K, at coronal density values for which emulated images of the Transition Region And Coronal Explorer(TRACE) 171 and 195 pass bands reproduce observed photon count rates.

Density waves in quasi-one-dimensional atomic gas mixture of boson and two-component fermion

description: We study the density-wave states of quasi-one-dimensional atomic gas mixture of one- and two-component boson and fermion using the mean-field approximation. Owing to the Peierls instability in the quasi-one-dimensional fermion system, the ground state of the system shows the fermion density wave and the periodic Bose-Einstein condensation induced by the boson-fermion interatomic interaction. For the two-component fermions, two density waves appear in these components, and the phase difference between them distinguishes two types of ground states, the in-phase and the out-phase density-waves. In this paper, a self-consistent method in the mean-field approximation is presented to treat the density-wave states in boson-fermion mixture with two-component fermions. From the analysis of the effective potential and the interaction energies calculated by this method, the density-waves are shown to appear in the ground state, which are in-phase or out-phase depending on the strength of the inter-fermion interaction. It is also shown that the periodic Bose-Einstein condensate coexists with the in-phase density-wave of fermions, but, in the case of the out-phase one, only the uniform condensate appears. The phase diagram of the system is given for the effective coupling constants.
