description: We express the optimization of entanglement witnesses for arbitrary bipartite states in terms of a class of convex optimization problems known as Robust Semidefinite Programs (RSDP). We propose, using well known properties of RSDP, several new sufficient tests for the separability of mixed states. Our results are then generalized to multipartite density operators.

description: Recent observation studies have revealed that earthquakes are classified into several different categories. Each category might be characterized by the unique statistical feature in the time series, but the present understanding is still limited due to their nonlinear and nonstationary nature. Here we utilize complex network theory to shed new light on the statistical properties of earthquake time series. We investigate two kinds of time series, which are magnitude and inter-event time (IET), for three different categories of earthquakes: regular earthquakes, earthquake swarms, and tectonic tremors. Following the criterion of visibility graph, earthquake time series are mapped into a complex network by considering each seismic event as a node and determining the links. As opposed to the current common belief, it is found that the magnitude time series are not statistically equivalent to random time series. The IET series exhibit correlations similar to fractional Brownian motion for all the categories of earthquakes. Furthermore, we show that the time series of three different categories of earthquakes can be distinguished by the topology of the associated visibility graph. Analysis on the assortativity coefficient also reveals that the swarms are more intermittent than the tremors.

description: The accelerated and disorderly urbanization process is one of the main causes of urban environmental deterioration. Anthropogeomorphological studies are technical instrument in the developing of strategic planning for any municipality. Thus, this article aims to present some of anthropogeomorphological interventions and environmental derivations caused by urban sprawl in the urban area of the city of Santa Maria, in the Brazilian State of Rio Grande do Sul, thus seeking to identify the changes in the elements that compose the relief. The methodology was based on the characterization and geomorphological subdivision and in the study of urban sprawl in different periods. The results indicate that the current situation of the city is characterized by the absence of compliance in land use planning, generated by constant growth and disordered densification of the population, causing chaotic forms of accommodation of urban land use over the relief compartments.

description: Asymmetric nuclear matter is studied in the frame of relativistic mean-field theory, using scalar-isoscalar sigma, vector-isoscalar omega meson together with their selfinteractions, vector-isovector rho meson with its cross-interaction with omega meson too, and scalar-isovector delta meson as degrees of freedom. The model is used to parameterize the nuclear matter properties results calculated by more fundamental Dirac-Brueckner-Hartree-Fock theory and thus to provide an effective DBHF model applicable also to finite nuclei. Vector omega-rho cross-interaction seems to be an useful degree of freedom for describing of the asymmetric nuclear matter, mostly due to its impact on density dependence of the symmetry energy.

description: Correspondence imaging can achieve positive-negative ghost images by just conditional averaging of partial patterns, without treating bucket intensities as weights. To explain its imaging mechanism, we develop a probability theory assuming the targets are of gray-scale and the thermal reference speckles obey an arbitrary independent and identical distribution. By both simulation and experiments, we find that the recovered values in each region of the same original gray value conditionally obey a Gaussian distribution. A crosspoint-to-standard-deviation ratio is used as the figure of merit to prove that the patterns with respect to larger bucket values generate a positive image with a higher quality, vice versa for negative one. This work complements the theory of ghost imaging.

description: The effects of particle size distribution (PSD) on coal dust explosion severity were investigated using a 20 L vessel. The severity was evaluated by the maximum explosion pressure (Pex), the maximum rate of pressure rise ((dP/dt)ex), and the time spans (t1, t2) between ignition and Pex and between ignition and (dP/dt)ex during a trial. These parameters of five coal samples with the same particle size span (PSS) and different PSD were measured at 250 g/m3. The results show that the explosion rate is greatly affected by PSD. When the finer particles account for 30 wt%, (dP/dt)ex increased significantly, whereas t1 and t2 values decreased. (dP/dt)ex, t1 and t2 are affected significantly by D10 and D50 (the particle size for which 10% and 50% of the particles by projection area) dust components. It is suggested that D10 and D50 should be considered when polydispersity is used to describe the PSD. D10, D50, and the Specific Surface Area(SSA) are related to these explosion parameters and provide the better description of the PSD. The smaller the particle size is, the more complete the particles combust and the smaller the calorific values of dust explosion products are.

Dust and the Infrared Kinematic Properties of Early-Type Galaxies
Creators: name: Silge, Julia D.

Year: 2003

description: We have obtained spectra and measured the stellar kinematics in a sample of 25 nearby early-type galaxies (with velocity dispersions from less than 100 km/s to over 300 km/s) using the near-infrared CO absorption bandhead at 2.29 microns. Our median uncertainty for the dispersions is ~10%. We examine the effects of dust on existing optical kinematic measurements. We find that the near-infrared velocity dispersions are in general smaller than optical velocity dispersions, with differences as large as 30%. The median difference is 11% smaller, and the effect is of greater magnitude for higher dispersion galaxies. The lenticular galaxies (18 out of 25) appear to be causing the shift to lower dispersions while the classical ellipticals (7 out of 25) are consistent between the two wavelength regimes. If uniformly distributed dust causes these differences, we would expect to find a correlation between the relative amount of dust in a galaxy and the fractional change in dispersion, but we do not find such a correlation. We do see correlations both between velocity dispersion and CO bandhead equivalent width, and velocity dispersion and Mg2 index. The differences in dispersion are not well explained by current models of dust absorption. The lack of correlation between the relative amount of dust and shift in dispersion possibly suggets that dust does not have a similar distribution from galaxy to galaxy. The CO equivalent widths of these galaxies are quite high (>10 angstroms for almost all), requiring the light at these wavelengths to be dominated by very cool stars.

description: We present and analyze a simplified stochastic $αΩ-$dynamo model which is designed to assess the influence of additive and multiplicative noises, non-normality of dynamo equation, and nonlinearity of the $α-$% effect and turbulent diffusivity, on the generation of a large-scale magnetic field in the subcritical case. Our model incorporates random fluctuations in the $α-$parameter and additive noise arising from the small-scale fluctuations of magnetic and turbulent velocity fields. We show that the noise effects along with non-normality can lead to the stochastic amplification of the magnetic field even in the subcritical case. The criteria for the stochastic instability during the early kinematic stage are established and the critical value for the intensity of multiplicative noise due to $α-$fluctuations is found. We obtain numerical solutions of non-linear stochastic differential equations and find the series of phase transitions induced by random fluctuations in the $α-$parameter.

description: The environment transformed by human action, combined with the technique produces changes otherthan those of natural origin, indicating the human capacity to create artificial morphologies in shortperiods of time. Thus, the new morphologies lead us to reflect on the inclusion of elements in theenvironment of technogenic origin and with its own time, transfigure and reshape the landscape relief.The needs of man as an individual or society encourage the development of several techniquesthat end up making man geological factor, with urban areas, the main breeding sitesof technogenic deposits. Thus this study aims to characterize, identify and spatialize thetechnogenic deposits in the district Camobi, in the municipality of Santa Maria / RS. For thepreparation and execution of the research focused on the literature review, which aims to support thedevelopment of theoretical and methodological research. The map material was prepared in thesoftawre Spring 4.2. The total area occupied by built technogenic deposits comprises about 2,48 Km²(248,24 ha) approximately 12%, classified with built deposits. It was observed that the deposits predominate in areas of industrial and institutional use, and its creation is not related to socialclasses in the area of study.

description: Prokaryotic CRISPR-Cas adaptive immune systems rely on small non-coding RNAs derived from CRISPR loci to recognize and destroy complementary nucleic acids. However, the mechanism of Type IV CRISPR RNA (crRNA) biogenesis is poorly understood. To dissect the mechanism of Type IV CRISPR RNA biogenesis, we determined the x-ray crystal structure of the putative Type IV CRISPR associated endoribonuclease Cas6 from Mahella australiensis (Ma Cas6-IV) and characterized its enzymatic activity with RNA cleavage assays. We show that Ma Cas6-IV specifically cleaves Type IV crRNA repeats at the 3ʹ side of a predicted stem loop, with a metal-independent, single-turnover mechanism that relies on a histidine and a tyrosine located within the putative endonuclease active site. Structure and sequence alignments with Cas6 orthologs reveal that although Ma Cas6-IV shares little sequence homology with other Cas6 proteins, all share common structural features that bind distinct crRNA repeat sequences. This analysis of Type IV crRNA biogenesis provides a structural and biochemical framework for understanding the similarities and differences of crRNA biogenesis across multi-subunit Class 1 CRISPR immune systems.

description: We introduce a new variational inference (VI) framework, called energetic variational inference (EVI). It minimizes the VI objective function based on a prescribed energy-dissipation law. Using the EVI framework, we can derive many existing Particle-based Variational Inference (ParVI) methods, including the popular Stein Variational Gradient Descent (SVGD) approach. More importantly, many new ParVI schemes can be created under this framework. For illustration, we propose a new particle-based EVI scheme, which performs the particle-based approximation of the density first and then uses the approximated density in the variational procedure, or "Approximation-then-Variation" for short. Thanks to this order of approximation and variation, the new scheme can maintain the variational structure at the particle level, and can significantly decrease the KL-divergence in each iteration. Numerical experiments show the proposed method outperforms some existing ParVI methods in terms of fidelity to the target distribution.

Turbulent cascade, bottleneck and thermalized spectrum in hyperviscous flows

description: In many simulations of turbulent flows the viscous forces $ν\nabla^2 {\bf u}$ are replaced by a hyper-viscous term $-ν_p(-\nabla^2)^{p}{\bf u}$ in order to suppress the effect of viscosity at the large scales. In this work we examine the effect of hyper-viscosity on decaying turbulence for values of $p$ ranging from $p=1$ (regular viscosity) up to $p=100$. Our study is based on direct numerical simulations of the Taylor-Green vortex for resolutions from $512^3$ to $2048^3$. Our results demonstrate that the evolution of the total energy $E$ and the energy dissipation $ε$ remain almost unaffected by the order of the hyper-viscosity used. However, as the order of the hyper-viscosity is increased ,the energy spectrum develops a more pronounced bottleneck that contaminates the inertial range. At the largest values of $p$ examined, the spectrum at the bottleneck range has a positive power-law behavior $E(k)\propto k^α$ with the power-law exponent $α$ approaching the value obtained in flows at thermal equilibrium $α=2$. This agrees with the prediction of Frisch et al. [Phys. Rev. Lett. 101, 144501 (2008)] who suggested that at high values of $p$, the flow should behave like the truncated Euler equations (TEE). Nonetheless, despite the thermalization of the spectrum, the flow retains a finite dissipation rate up to the examined order, which disagrees with the predictions of the TEE system implying suppression of energy dissipation. We reconcile the two apparently contradictory results, predicting the value of $p$ for which the hyper-viscous Navier-Stokes goes over to the TEE system and we discuss why thermalization appears at smaller values of $p$.

Elastic and inelastic SU(3)-breaking final-state interactions in B decays to pseudoscalar mesons

description: We discuss all contributions from Zweig-rule-satisfying SU(3)-breaking final state interactions (FSIs)in the B -> PP decays (neglecting charmed intermediate states), where PP=pi pi, pi K, KK, pi eta (eta'), and K eta (eta'). First, effects of SU(3) breaking in rescattering through Pomeron exchange are studied. Then, after making a plausible assumption concerning the pattern of SU(3) breaking in non-Pomeron FSIs, we give general formulas for how the latter modify short-distance (SD) amplitudes. In the SU(3) limit, these formulas depend on three effective parameters characterizing the strength of all non-Pomeron rescattering effects. We point out that the experimental bounds on the B -> K^+K^- branching ratio may limit the value of only one of these FSI parameters. Thus, the smallness of the B -> K^+K^- decay rate does not imply negligible rescattering effects in other decays. Assuming a vanishing value of this parameter, we perform various fits to the available B -> PP branching ratios. The fits determine the quark-diagram SD amplitudes, the two remaining FSI parameters and the weak angle gamma. While the set of all B -> PP branching ratios is well described with gamma around its expected SM value, the fits permit other values of gamma as well. For a couple of such good fits, we predict asymmetries for the B -> K pi, pi^+ eta (eta'), K^+ eta (eta') decays as well as the values of the CP-violating parameters S_{pi pi} and C_{pi pi} for the time-dependent rate of B^0(t) -> pi^+ pi^-. Apart from a problem with the recent B^+ -> pi^+ eta asymmetry measurement, comparison with the data seems to favour the values of gamma in accordance with SM expectations.

description: The shot-noise detection limit in current high-precision atomic magnetometry is a manifestation of quantum fluctuations that scale as the square root of N in an ensemble of N particles. However, there is a general expectation that the reduced projection noise provided by conditional spin-squeezing could be exploited to surpass the conventional shot-noise limit. We show that continuous measurement coupled with quantum Kalman filtering provides an optimal procedure for magnetic detection limits that scale with 1/N, the Heisenberg squeezing limit. Our analysis demonstrates the importance of optimal estimation procedures for high bandwidth precision magnetometry.

description: In heart failure (HF) patients, early stages are associated with increased iron levels, whereas iron deficiency is a common feature of chronic HF. We investigated the acute and long-term changes in iron metabolism in HF patients after immunoadsorption treatment and intravenous immunoglobulin (IVIG) administration. Twenty-seven patients with HF with reduced ejection fraction (HFrEF) received a single cycle of immunoadsorption followed by IVIG administration. Left ventricular ejection fraction (LVEF) and iron biomarker (ferritin, hepcidin and interleukin-6) were evaluated at baseline, after immunoadsorption and during long-term follow-up of 29.3 months. LVEF improved significantly after immunoadsorption treatment from baseline 27% to 43% at long-term follow-up. Ferritin decreased from baseline 300.2 to 201.3 ng/mL (p Our data suggest that initial high serum ferritin and hepcidin levels indicate elevated iron levels characteristic of early stages of HFrEF, without inflammation. Normalization of hepcidin and ferritin was paralleled by restoration of systolic cardiac function after immunoadsorption treatment, without development of iron deficiency, as usually observed in chronic HF.

description: The purpose of this paper is to introduce a model for measuring the efficiency in managing peer-review of scientific manuscripts by editors. The approach employed is based on the assumption that the editorial aim is to manage publication with high efficiency, employing the least amount of editorial resources. Efficiency is defined in this research as a measure based on 7 variables. An on-line survey was constructed and editors of journals originating from Serbia regularly publishing articles in the field of chemistry were invited to participate. An evaluation of the model is given based on responses from 24 journals and 50 editors. With this investigation we aimed to contribute to our understanding of the peer-review process and, possibly, offer a tool to improve the "efficiency" in journal editing. The proposed protocol may be adapted by other journals in order to assess the managing potential of editors.

description: The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) provides a rich resource for investigating the galaxies populating the local Universe. A full characterization of the large-scale clustering distribution is important for theoretical studies of structure formation. 2MASS offers an all-sky view of the local galaxy population at 2.15 micron, unbiased by young stellar light and minimally affected by dust. We use 2MASS to map the local distribution of galaxies, identifying the largest structures in the nearby universe. The inhomogeneity of these structures causes an acceleration on the Local Group of galaxies, which can be seen in the dipole of the Cosmic Microwave Background (CMB). We find that the direction of the 2MASS clustering dipole is 11 degrees from the CMB dipole, confirming that the local galaxy distribution accelerates the Local Group. From the magnitude of the dipole we find a value of the linear bias parameter b=1.37 +/- 0.3 in the K_s-band. The 2MASS clustering dipole is 19 degrees from the latest measurement of the dipole using galaxies detected by the Infrared Astronomical Satellite (IRAS) suggesting that bias may be non-linear in some wavebands.

description: We consider the integral and derivative operators of tempered fractional calculus, and examine their analytic properties. We discover connections with the classical Riemann-Liouville fractional calculus and demonstrate how the operators may be used to obtain special functions such as hypergeometric and Appell's functions. We also prove an analogue of Taylor's theorem and some integral inequalities to enrich the mathematical theory of tempered fractional calculus.

description: Are the classical singularities of general relativistic spacetimes, normally defined by the incompleteness of classical particle paths, still singular if quantum mechanical particles are used instead? This is the question we will attempt to answer for particles obeying the quantum mechanical wave equations for scalar, null vector and spinor particles. The analysis will be restricted to certain static general relativistic spacetimes that classically contain the mildest true classical singularities, quasiregular singularities.

description: Beta Laguerre processes which are generalizations of the eigenvalue process of Wishart/Laguerre processes can be defined as the square of radial Dunkl processes of type B. In this paper, we study the limiting behavior of their empirical measure processes. By the moment method, we show the convergence to a limit in a high temperature regime, a regime where $βN \to const \in (0, \infty)$, where $β$ is the inverse temperature parameter and $N$ is the system size. This is a dynamic version of a recent result on the convergence of the empirical measures of beta Laguerre ensembles in the same regime.

Adaptive Mesh Refinement for Topology Optimization with Discrete Geometric Components

description: This work introduces an Adaptive Mesh Refinement (AMR) strategy for the topology optimization of structures made of discrete geometric components using the geometry projection method. Practical structures made of geometric shapes such as bars and plates typically exhibit low volume fractions with respect to the volume of the design region they occupy. To maintain an accurate analysis and to ensure well-defined sensitivities in the geometry projection, it is required that the element size is smaller than the smallest dimension of each component. For low-volume-fraction structures, this leads to finite element meshes with very large numbers of elements. To improve the efficiency of the analysis and optimization, we propose a strategy to adaptively refine the mesh and reduce the number of elements by having a finer mesh on the geometric components, and a coarser mesh away from them. The refinement indicator stems very naturally from the geometry projection and is thus straightforward to implement. We demonstrate the effectiveness of the proposed AMR method by performing topology optimization for the design of minimum-compliance and stress-constrained structures made of bars and plates.

description: Mineral nutrient requirements of Cannabis sativa ‘cherry wine’ (hemp) were studied under steady-state nutrition where nutrients and water (H2O) removed via transpiration uptake were replenished daily. Nitrate (NO3−), potassium (K+), and H2O uptake for hemp are presented for 24 h periods over the course of vegetative growth. This can estimate the changes in potential NO3− and K+ uptake rate in accordance with demand. Daily nutrient uptake and transpiration rates are discussed relative to the plant's H2O uptake and relative growth rate. Non-limiting conditions were achieved at base nutrient recipe NO3− and K+ concentrations of 201 and 290 ppm. Biomass accumulation and stem caliper increment increase over the vegetative growth cycle were found to have a positive linear correlation with NO3−, K+, and H2O uptake. Consequently, NO3− and K+ concentrations in the irrigation solution can be steadily increased throughout the hemp vegetative cycle in relation to the driving relative variables growth and transpiration rate. In so doing, a time dimension is introduced concerning the nutrient amount supplied relative to plant biomass accumulation and nutrient uptake via the transpiration stream. Overall, lower amounts of NO3− and K+ were needed to optimize plant growth than previously thought by industry professionals.

description: Based on the self-energy-functional approach proposed recently [M. Potthoff, Eur. Phys. J. B 32, 429 (2003)], we present an extension of the cluster-perturbation theory to systems with spontaneously broken symmetry. Our method applies to models with local interactions and accounts for both short-range correlations and long-range order. Short-range correlations are accurately taken into account via exact diagonalization of finite clusters. Long-range order is described by variational optimization of a ficticious symmetry-breaking field. In comparison with related cluster methods, our approach is more flexible and, for a given cluster size, less demanding numerically, especially at zero temperature. An application of the method to the antiferromagnetic phase of the Hubbard model at half-filling shows good agreement with results from quantum Monte-Carlo calculations. We demonstrate that the variational extension of the cluster-perturbation theory is crucial to reproduce salient features of the single-particle spectrum.

We compare two different approximations both referred to as Rotating Wave Approximation. Using a specific example, we clarify some issues related to non--Markovian dynamics, non--Lindblad type dynamics, and positivity of the density matrix.

description: We propose a quadratic unconstrained binary optimization (QUBO) formulation of the l1-norm, which enables us to perform sparse estimation of Ising-type annealing methods such as quantum annealing. The QUBO formulation is derived using the Legendre transformation and the Wolfe theorem, which have recently been employed to derive the QUBO formulations of ReLU-type functions. It is shown that a simple application of the derivation method to the l1-norm case results in a redundant variable. Finally a simplified QUBO formulation is obtained by removing the redundant variable.

description: Could we see the difference between Baden-Powell’s two types of village tenures - the raiyatwāri village and the joint village - as the difference between farming in the alluvial plains and farming in the more difficult terrain ? In this context, we need to note the circumstance highlighted by Filippe Nery Xavier; he points out that wherever or whenever the sovereign or his agents are extortive in their collection of tax or tribute, the very idea of property tends to get extinguished. [Xavier, 1907 : Bosquejo Historico das Comunidades das Aldeas dos Concelhos das Ilhas, Salcete e Bardez, Vol. 1, 75] Deccan has chronically suffered from low crop productivity and frequent droughts. Its plight has been described in several narrations, and archaeobotanical studies. In such circumstances any stable village tenure system in that territory would have been under threat. In fact Arcamone categorically speaks of “the farmers of the hinterland, hard pressed by debts or taxes, renounced the land and the king, fled with household utensils and cattle, and came to this peninsula so that they may be able to cultivate it for their livelihood.” (Fernandes, 1981: Uma Descrição e Relação de ‘De Sasatana Peninsula in IndiaeStatu’ Textus Inediti, 94)
