A Model System of Mixed Ionized Gas Dynamics

description: The aim of this paper is to study a one dimensional model system of equations for ionized gas dynamics at high temperature where the gas is a mixture of two kinds of monatomic gas. In addition to the mass density, pressure, temperature and particle velocity, degrees of ionization of both gases are also involved. By assuming that the local thermal equilibrium is attained, Saha's ionization equations are added. Thus the equations are supplemented by the first and second law of thermodynamics, a single equation of state and, in addition, a set of thermodynamic equations. The equations constitute a strictly hyperbolic system, which guarantees that the initial value problem is well-posed locally in time for sufficiently smooth initial data. However the geometric properties of the system are rather complicated: in particular, we prove the existence of a region where convexity (genuine nonlinearity) fails for forward and backward characteristic fields. Also we study thermodynamic properties of shock waves by a detailed analysis of the Hugoniot locus, which is used in a mathematical study of existence and uniqueness of solutions to the shock tube problem.

description: The original idea to show the spacetime geometry using few geodesics was developed by Johnson and Ruffini (1974). We used this idea to interpret the observational data for rotating BH's. We developed the imitation approach to simulate a propagation of radiation near BH's. An important problem for this approach is the diagnostics of a black hole metric using X-ray observational data of the iron $K_α$-line. Observations of Seyfert galaxies in X-ray region reveal the broad emissiion lines in their spectra, which can arise in inner parts of accretion disks, where the effects of General Relativity (GR) must be counted. A spectrum of a solitary emission line (the $K_α$-line of iron, for example) of a hot spot in Kerr accretion disk is simulated, depending on the radial coordinate $r$ and the angular momentum $a=J/M$ of a black hole, under the assumption of an equatorial circular motion of a hot spot. Using results of numerical simulations it is shown that the characteristic two-peak line profile with the sharp edges arises at a large distance, (about $r \approx (3-10)r_g$). The inner regions emit the line, which is observed with one maximum and extremely broad red wing. High accuracy future spectral observations, being carried out, could detect the angular momentum $a$ of the black hole. We analyzed the different parameters of problems on the observable shape of this line and discussed some possible kinds of these shapes. The total number of geodesics is about $10^9$ (to simulate possible shapes of the $K_α$-line), so the number is great enough, especially in comparison with few geodesics in the original paper by Johnson and Ruffini (1974).

description: We search for possible correlations between neutron star observables and thermodynamic quantities that characterize high density nuclear matter. We generate a set of model-independent equations of state describing stellar matter from a Taylor expansion around saturation density. Each equation of state which is a functional of the nuclear matter parameters is thermodynamically consistent, causal and compatible with astrophysical observations. We find that the neutron star tidal deformability and radius are strongly correlated with the pressure, the energy density and the sound velocity at different densities. Similar correlations are also exhibited by a large set of mean-field models based on non-relativistic and relativistic nuclear energy density functionals. These model independent correlations can be employed to constrain the equation of state at different densities above saturation from measurements of NS properties with multi-messenger observations. In particular, precise constraints on the radius of PSR J0030+0451 thanks to NICER observations would allow to better infer the properties of matter around two times the nuclear saturation density.

description: Human-modified habitats form increasingly large components of landscapes, threatening biodiversity and creating challenges for conservation. In some cases altered habitats form entirely novel ecosystems that may support new combinations of species and species abundances, and create habitat space in otherwise transformed landscapes. In the Western Cape of South Africa, woody invasive species contribute to landscape-level habitat transformation and form novel ecosystems. Invasive Australian Acacia species are especially problematic in lowland areas where they create dense thickets and substantially transform both biotic communities and abiotic processes. Despite the prominence of Acacia thickets across the Western Cape, their ability to support native fauna is not well understood and the objective of this study was to assess the significance of Acacia thickets as habitat for the region's avifauna. Birds were surveyed in Acacia thickets in the south-western Western Cape in three seasons to examine species richness, abundance and functional abundance. Furthermore, I examined the extent to which differences in patch-level vegetation structure alter bird communities. Between survey sites and seasons, significant variation was observed in assemblage richness, density, median body size and biomass. Variation in vegetation density, stem density, mean vegetation height and total canopy cover best explained variation in bird assemblages. Eighty species were estimated to utilize Acacia thickets and assemblages had a mean density of 7.78 birds per ha. The most abundant feeding guilds were the mixed feeders and insectivores. The median body size observed was 15.2 g and the body size frequency distribution of all species in Acacia spanned a similar range compared to the body size frequency distribution for the species list for the entire Western Cape. The mean biomass of bird communities was 0.224 kg per ha. Using data on bird density and biomass, Acacia thickets across the Fynbos Biome support and estimated average of over 21 million birds with a combined biomass of over 600 thousand kg. This study found that Acacia thickets in the Western Cape support a subset of the region's birds with the most abundant species being small mixed feeders, which are also frequently urban-adapted. Compared with other habitat types, Acacia support bird assemblages with moderate species richness and density. This study shows that Acacia thickets, as a novel habitat, provide a significant amount of habitat space in a highly transformed landscape and highlights the need for comprehensive evaluation of altered habitats before assumptions are made about their ecological value.

description: Non-degenerate perturbation theory, which was used to calculate the scale dimension of operators on the gauge theory side of the correspondence, breaks down when effects of triple trace operators are included. We interpret this as an instability of excited single-string states in the dual string theory for decay into the continuum of degenerate 3-string states. We apply time-dependent perturbation theory to calculate the decay widths from gauge theory. These widths are new gauge theory data which can be compared with future calculations in light cone string field theory.

description: In this paper we derive the Modified Friedmann equation in the Palatini formulation of $R^2$ gravity. Then we use it to discuss the problem of whether in Palatini formulation a $R^2$ term can drive an inflation. We show that the Palatini formulation of $R^2$ gravity cannot lead to gravity-driven inflation. If considering no zero radiation and matter energy densities, we show that only under rather restrictive assumption about the radiation and matter energy densities there will be a mild power-law inflation $a\sim t^2$.

Component-based regularisation of multivariate generalised linear mixed models

Year: 2019
Subjects: subject: Statistics Theory (math.ST)

description: We address the component-based regularisation of a multivariate Generalised Linear Mixed Model (GLMM) in the framework of grouped data. A set Y of random responses is modelled with a multivariate GLMM, based on a set X of explanatory variables, a set A of additional explanatory variables, and random effects to introduce the within-group dependence of observations. Variables in X are assumed many and redundant so that regression demands regularisation. This is not the case for A, which contains few and selected variables. Regularisation is performed building an appropriate number of orthogonal components that both contribute to model Y and capture relevant structural information in X. To estimate the model, we propose to maximise a criterion specific to the Supervised Component-based Generalised Linear Regression (SCGLR) within an adaptation of Schall's algorithm. This extension of SCGLR is tested on both simulated and real grouped data, and compared to ridge and LASSO regularisations. Supplementary material for this article is available online.

description: The constraints on tidal deformability $Λ$ of neutron stars are first extracted from GW170817 by LIGO and Virgo Collaborations but the relation between radius $R$ and tidal deformability $Λ$ is still nuder debate. Using an isospin-dependent parameterized equation of state (EOS), we study the relation between $R$ and $Λ$ of neutron stars and its dependence on parameters of symmetry energy $E_{\rm sym}$ and EOS of symmetric nuclear matter $E_0$ when the mass is fixed as $1.4$ $M_\odot$, $1.0$ $M_\odot$, and $1.8$ $M_\odot$, respectively. We find that, though the changes of high order parameters of $E_{\rm sym}$ and $E_0$ can shift the individual values of $R_{1.4}$ and $Λ_{1.4}$ to different values, the $R_{1.4}\simΛ_{1.4}$ relation approximately locates at the same fitted curve. The slope of symmetry energy $L$ plays the dominated role in determining the $R_{1.4}\simΛ_{1.4}$ relation. By checking the mass dependence of $R\simΛ$ relation, the well fitted $R\simΛ$ relation for 1.4 $M_\odot$ is broken for massive neutron stars.

description: A high production rate of negative hydrogen ion was observed from a nanoporous C12A7 electride surface immersed in hydrogen/deuterium low-pressure plasmas. The target was biased at 10-170 V negatively and the target surface was bombarded by H3 + ions from the plasma. The production rate was 1-2 orders higher than a clean molybdenum surface. The measured H-energy spectrum indicates that the major production mechanism is desorption by sputtering. This material has potential to be used as production surface of cesium-free negative ion sources for accelerators, heating beams in nuclear fusion, and surface modification for industrial applications.

description: This paper aims to analyse the evolution of a small western African nation, Benin, from rule by the military (militocracy) to rule by the rich (plutocracy). In the aftermath of its independence, Benin experienced 5 military coups in 9 years and again 5 coup attempts in the following 20 years. The militocratic chaos, which emerged as a result of ethnopolitical power struggle, was replaced by a Marxist-Leninist government led by Mathieu Kerekou. Having served as the President of Benin for almost 30 years, Kerekou followed a chameleon-like politics by converting from a religion to another and from an ideology to another. His government did not act in a strictly ideological way and therefore easily adopted neoliberalism in the post-Cold War period. The governments of Thomas Boni Yayi and Patrice Talon who came to power after the adoption of liberalisation initially had a democratic profile but later they tended to be authoritarian. Being led by Talon, a former “cotton tycoon”, the incumbent government went beyond authoritarian democracy and has paved the way for a future plutocracy by adopting a new electoral code that requires candidates vying for presidency and membership of parliament to have a financial deposit over 400,000 dollars. How these diverse political mind-sets emerged in Benin is the main question we aim to answer in this paper

description: We introduce an extension of the usual replicator dynamics to adaptive learning rates. We show that a population with a dynamic learning rate can gain an increased average payoff in transient phases and can also exploit external noise, leading the system away from the Nash equilibrium, in a reasonance-like fashion. The payoff versus noise curve resembles the signal to noise ratio curve in stochastic resonance. Seen in this broad context, we introduce another mechanism that exploits fluctuations in order to improve properties of the system. Such a mechanism could be of particular interest in economic systems.

description: The main objectives of this research are to examine and test predictions relating to the relationship between occupancy, abundance, aggregation, and scale on Marion Island. Additionally, the impact of terrestrial invasive species on indigenous plant species is investigated, and particularly how they interact with the indigenous plants and each other. The thesis is split into five chapters, with the first chapter being a general introduction to topics of species abundance and distribution patterns as well as alien species in the sub-Antarctic. In chapter two, the generality of the abundant centre hypothesis (Brown 1984) is tested by examining the geographic abundance structure of Azorella selago at an island-wide scale. In the third chapter, the impact of alien house mice on A. selago as well as the spatial variation in structural damage to A. selago by mice is investigated at a landscape scale. The fourth chapter focuses on the distribution and spatial patterns of two alien vascular plant species, Agrostis stolonifera and Sagina procumbens, and the indigenous Acaena magellanica and how they interact with each other along rivers. In the fifth and final chapter, the general findings for each chapter (chapters 2-4) are summarised and synthesised, and the possible implications and influences of the alien species on macroecological patterns of Marion Island's indigenous biota are discussed.

Applying this principle to Newton's law with the simplest measurement theory leads to Lagrangian mechanics, while use of conformal measurement theory leads to Hamilton's equations.

description: The multifractal formalism characterizes the scaling properties of a physical density rho as a function of the distance L. To each singularity alpha of the field is attributed a fractal dimension for its support f(alpha). An alternative representation has been proposed by Jensen considering the distribution of distances associated to a fixed mass. Computing these spectra for a multifractal Cantor set, it is shown that these two approaches are dual to each other, and that both spectra as well as the moment scaling exponents are simply related. We apply the same inversion formalism to exponents obtained for turbulent statistics in the GOY shell model and observe that the same duality relation holds here.

description: The paper is devoted to the analysis of particle acceleration in Gamma-Ray Bursts and its radiative consequences. Therefore we get on one hand constraints on the physics and on the other hand possible signatures of particle acceleration that could be recorded by the new gamma ray instruments. We have previously shown that UHECRs can be generated in GRBs even with conservative assumptions on the magnetic field and the scattering capability of its perturbations, provided that a suitable relativistic Fermi process is at work during the so-called "internal shock" phase. We extend here the analysis of the consequences of these assumptions to the whole prompt emission of both electrons and protons. Indeed, assuming that the magnetic field decays in $1/r^2$ and that the scattering time of particles is longer than the Bohm's assumption, in particular with a rule derived from Kolmogorov scaling, we show with no other parameter adaptation that the intensity of the subequipartition magnetic field, that: i) UHECRs can be generated with a sufficient flux within the GZK-sphere to account for the CR-spectrum at the ankle. ii) The peak energy of the gamma spectrum around 100 keV, namely the so-called $E_{peak}$, is conveniently explained. iii) A thermal component below the $E_{peak}$ is often unavoidable. iv) The cosmic rays could radiate gamma rays around 67 MeV (in the co-moving frame, which implies $\simeq 20$ GeV for the observer) due to $π^0$-decay and a low energy neutrino emission (around 0.2 GeV) associated to neutron decay and also neutrinos of energy between 5 and 150 GeV from muon decay. v) The UHECRs radiate high energy gamma rays between a few tens of MeV and 10 GeV (taking the pair creation process into account) due to their synchrotron emission with a sufficient flux to be observable.

description: The ensemble of 2,6-bis(2-chlorophenyl)dithiazolo[4,5-b:5',4'-e]pyridine 1 with Pd2+ ions (1•Pd2+) was prepared for the detection of cyanide ions (CN¯) in 50% aqueous methanol. Among the tested metal ions, only Pd2+ sensitively induced the red shift of the absorption bands and the complete decrease of fluorescence emission. The detection limit toward Pd2+ was 2 ppb. The ensemble 1•Pd2+ selectively and rapidly detected a low concentration of cyanide ions by a colorimetric change (40 ppb) as well as a “turn-on” fluorescent response (5 ppb). Job’s plot revealed the complex formation with 1:1 stoichiometry. The binding and replacement mode of 1•Pd2+ and CN¯ were also confirmed by 1H NMR titrations and IR analysis. In general, a fast and selective recognition of CN¯ is reported.

description: Studies of the Fundamental Plane of early-type galaxies, from small to intermediate redshifts, are often carried out under the guiding principle that the Fundamental Plane reflects the existence of an underlying mass-luminosity relation for such galaxies, in a scenario where elliptical galaxies are homologous systems in dynamical equilibrium. Here I will re-examine the issue of whether empirical evidence supports the view that significant systematic deviations from strict homology occur in the structure and dynamics of bright elliptical galaxies. In addition, I will discuss possible mechanisms of dynamical evolution for these systems, in the light of some classical thermodynamical arguments and of recent N-body simulations for stellar systems under the influence of weak collisionality.

description: O artigo discute as diferenças de desempenho produtivo entre 114 países, com base na metodologia de Análise Envoltória de Dados (DEA). Tendo como motivação o fato de que os modelos tradicionais de crescimento econômico raramente examinam os problemas ecológicos gerados por uma sociedade capitalista moderna, assim este tipo de modelo não se aproxima de problemas essenciais da realidade atual. Os dados utilizados foram extraídos do Banco Mundial e ESI no ano de 2002. Os resultados indicam que os paises Kuwait e Trinidad e Tobago possuem maior eficiência na transformação de capital físico e capital natural (insumos) em crescimento/desenvolvimento (PIB per capita), de forma a orientar os agentes produtivos na busca contínua da melhor alocação dos fatores de produção, e ainda na dinâmica do desenvolvimento econômico.

description: The American economy can be thought of as a highly connected random network in terms of both its technological and informational connections. The cumulative size of economic recessions, the fall in output from peak to trough, is analysed for the US economy 1900-2002. A least squares fit of an exponential relationship between size and the rank of size gives a good description of most of the data. But the observation for the Great Depression of the 1930s stands out as a very distinct outlier. In other words, we observe a bimodal relationship of the type predicted by theory.

Nestedness and compartmentalisation
Masters

description: Designing a mechanistic model that can give rise to realistic architecture of ecological networks is central to the understanding of how species assemble and function in ecosystems. As species are constantly adjusting their diets in an antagonistic network, we here incorporate this adaptive behaviour of diet choice into a bipartite network model, with the effect of antagonistic interactions between species depicted by Holling's type II functional response. Predictions of this model fit extremely well with the observed levels of nestedness, modularity and node-degree distributions for 61 real host-parasitoid and plant-herbivore networks. We further examined two specific scenarios of our model (species with identical [neutral] demographic parameters and interactions with identical [neutral] benefit in the network) and found that the demography-neutral scenario overestimated observed modularity, whilst the benefit neutral scenario overestimate observed nestedness. Relationships between nestedness, modularity and connectance were found strong. Moreover, in contrast to the common belief of the high modularity in antagonistic networks, most real networks (> 80%) are significantly nested, whilst nearly 40% of the real networks are surprisingly less compartmentalized than random networks generated from null models. Regardless of the controversy on whether antagonistic networks are nested or compartmentalized, the proposed model captured the essence of the dynamic nature of structural emergence in antagonistic networks. Due to its predictive power, this model was further used to investigate robustness in antagonistic networks. Predictions showed that the robustness of a network is determined by many factors, such as connectance, resource degree distribution, resource-consumer ratio, diversity, nestedness and compartmentalisation. Surprisingly, the manner of network response to species loss was independent of the sequence followed while removing species from a network. Variations were only noticed in the intensity of the effect resulting from the removals. In addition, we also showed that species extinction procedures which ignore the interaction switch underestimate the effect of any loss of species in these networks. We must therefore value our knowledge of possible adaptive processes in the ecosystem as they may be important for resolving the diversity-stability debate.

description: São vários os exemplos de agroindústrias familiares com características semelhantes à agroindústria da Colônia Nova, no Vale do Rio Uruguai/RS, que estão buscando se inserir no mercado de produtos orgânicos e muitas vezes, superar problemas econômicos ligados à formulação de estratégias de produção e comercialização. O objetivo deste estudo foi identificar as estratégias de marketing formadas e formuladas no processo de agroindustrialização, os quais estão voltados para o processo produtivo e de comercialização da produção das unidades agroindustriais familiares. Bem como, o porquê da utilização de novos produtos com potenciais agrícolas, agroindustriais e comerciais e que apresentam alternativas viáveis para o aumento da produção e da renda dos agricultores familiares. O trabalho apresenta as estratégias desenvolvidas e utilizadas pela agroindústria para a produção, a distribuição, a promoção e a apresentação dos produto ao mercado consumidor. Com a identificação das estratégias de marketing utilizadas desde a produção até a comercialização da cachaça orgânica produzida na agroindústria, este trabalho, apresenta dados que poderão contribuir para que estabelecimentos com problemas e potencialidades semelhantes possam desenvolver-se de forma mais integrada. E auxiliar a formulação de políticas públicas mais abrangentes quanto à agregação de valor no meio rural.

description: Kachru, Kallosh, Linde, & Trivedi recently constructed a four-dimensional de Sitter compactification of IIB string theory, which they showed to be metastable in agreement with general arguments about de Sitter spacetimes in quantum gravity. In this paper, we describe how discrete flux choices lead to a closely-spaced set of vacua and explore various decay channels. We find that in many situations NS5-brane meditated decays which exchange NSNS 3-form flux for D3-branes are comparatively very fast.

Strong Gravitational Lensing and the Structure of Quasar Outflows

description: We show that by analyzing the spectra of lensed broad absorption line quasars (BALQSOs), it is possible to reveal key properties of the outflowing gas in the inner regions of these objects. This results from the fact that each image of the quasar corresponds to a different line of sight through the outflow. This combined with dynamical estimates for the location of the flow, adds new information concerning the lateral, non line of sight structure of the absorbing gas. Here we consider a sample of lensed BALQSOs and note that the similarity of BAL profiles of different images of the same quasar implies that the flow is relatively isotropic on small scales. We show that its geometry is inconsistent with the ballistically accelerated spherical cloud model, and that wind models provide a better description of the flow structure. Furthermore, observations seem to disagree with naive interpretations of recent time-dependent wind simulations. This may hint on several important physical processes that govern the structure and dynamics of such flows. Future prospects for the study of quasar outflows with the effect of strong gravitational lensing are discussed.

description: We construct a solution of the BFSS matrix theory, which is a counterpart of the BIon solution representing a fundamental string ending on a bound state of a D2-brane and D0-branes. We call this solution the `fuzzy BIon' and show that this configuration preserves 1/4 supersymmetry of type IIA superstring theory. We also construct an effective action for the fuzzy BIon by analyzing the nonabelian Born-Infeld action for D0-branes. When we take the continuous limit, with some conditions, this action coincides with the effective action for the BIon configuration.

description: Esse artigo tem como objetivo discutir as externalidades negativas associadas à contaminação do solo e da água devido ao uso de agrotóxicos nos municípios do cerrado brasileiro, área em franca expansão da atividade agrícola, cujo modelo produtor baseia-se no uso intensivo de agroquímicos (agrotóxicos e fertilizantes). Embora, no presente trabalho, não se valore as externalidades provenientes do uso dos agrotóxicos, aponta alguns fatores preditores da contaminação na água e no solo por esses produtos nos municípios do cerrado brasileiro. Os dados foram obtidos por meio da Pesquisa de Informações Básicas Municipais (MUNIC/IBGE), cujo ano de 2003 veio a campo com um questionário suplementar com questões atinentes ao meio ambiente dos municípios brasileiros. Adicionalmente, procurou-se associar, por meio de mapas, áreas contaminadas e o grau de atividade agrícola dos municípios, captado pela Pesquisa Agrícola Municipal (PAM/IBGE 2003). Por meio de uma regressão logistica, foi possível encontrar alguns fatores de risco da contaminação no solo e na água por agrotóxicos e fertilizantes. Caraterísticas como aumento da área de lavoura temporária, poluição no ar por queimadas e por atividade agropecuária, proliferação de pragas e municípios situados nas Regiões Sul, Sudeste e Centro Oeste aumentam as chances de contaminação, ao passo que municípios que promovem a educação ambiental reduzem as chances de ocorrência desse problema. Conclui-se que o presente trabalho serve como referência para os formuladores de políticas no sentido de auxiliar o desenho dos instrumentos de regulação e o diagnóstico das áreas em que essas ações devem ser tomadas como prioritárias.

description: We use a real-space renormalization group (RSRG) to study the low temperature dynamics of kinetically constrained Ising chains (KCICs). We consider the cases of the Fredrickson-Andersen (FA) model, the East model, and the partially asymmetric KCIC. We show that the RSRG allows one to obtain in a unified manner the dynamical properties of these models near their zero-temperature critical points. These properties include the dynamic exponent, the growth of dynamical lengthscales, and the behaviour of the excitation density near criticality. For the partially asymmetric chain the RG predicts a crossover, on sufficiently large length and time scales, from East-like to FA-like behaviour. Our results agree with the known results for KCICs obtained by other methods.
