description: A novel numerical approach to solving the shallow-water equations on the sphere using high-order numerical discretizations in both space and time is proposed. A space-time tensor formalism is used to express the equations of motion covariantly and to describe the geometry of the rotated cubed-sphere grid. The spatial discretization is done with the direct flux reconstruction method, which is an alternative formulation to the discontinuous Galerkin approach. The equations of motion are solved in differential form and the resulting discretization is free from quadrature rules. It is well known that the time step of traditional explicit methods is limited by the phase velocity of the fastest waves. Exponential integration is employed to enable integrations with significantly larger time step sizes and improve the efficiency of the overall time integration. New multistep-type exponential propagation iterative methods of orders 4, 5 and 6 are constructed and applied to integrate the shallow-water equations in time. These new schemes enable time integration with high-order accuracy but without significant increases in computational time compared to low-order methods. The exponential matrix functions-vector products used in the exponential schemes are approximated using the complex-step approximation of the Jacobian in the Krylov-based KIOPS (Krylov with incomplete orthogonalization procedure solver) algorithm. Performance of the new numerical methods is evaluated using a set of standard benchmark tests.

description: Using a combination of theory and computer simulations, we study the translocation of an RNA molecule, pulled through a solid-state nanopore by an optical tweezer, as a method to determine its secondary structure. The resolution with which the elements of the secondary structure can be determined is limited by thermal fluctuations. We present a detailed study of these thermal fluctuations, including the frequency spectrum, and show that these rule out single-nucleotide resolution under the experimental conditions which we simulated. Two possible ways to improve this resolution are strong stretching of the RNA with a back-pulling voltage across the membrane, and stiffening of the translocated part of the RNA by biochemical means.

description: Food insecurity is more worrisome now than ever before due to unprecedented climate variability and widespread rural poverty. Research-based and policy relevant empirical evidence is crucial to design strategies to address food insecurity in the face of climate variability. Thus, this study examines the status of food insecurity among households’ and its determinants in North Shewa Zone of Amhara Region using cross-sectional data collected from 382 sample households. Households’ food insecurity status was determined by comparing the total calorie available for consumption per adult equivalent to the minimum level of subsistence requirement per adult equivalent of 2200 kcal. Logistic regression model was used to identify factors that influence food insecurity status of households in the study area. Accordingly, the results of the study show that majority (56.28%) of the sample households in the study area were food insecure. In addition, results revealed that age, literacy, cultivated land size, soil fertility status, number of oxen owned and irrigation water use were the major factors negatively associated with food insecurity. In contrast, sex, household size, distance to the main market and rainfall variability have increased the probability of being food insecure. The findings imply that majority of the households are food insecure where its improvement can be addressed through appropriate policy, institutional and technological options.

description: We propose a Healthcare Graph Convolutional Network (HealGCN) to offer disease self-diagnosis service for online users based on Electronic Healthcare Records (EHRs). Two main challenges are focused in this paper for online disease diagnosis: (1) serving cold-start users via graph convolutional networks and (2) handling scarce clinical description via a symptom retrieval system. To this end, we first organize the EHR data into a heterogeneous graph that is capable of modeling complex interactions among users, symptoms and diseases, and tailor the graph representation learning towards disease diagnosis with an inductive learning paradigm. Then, we build a disease self-diagnosis system with a corresponding EHR Graph-based Symptom Retrieval System (GraphRet) that can search and provide a list of relevant alternative symptoms by tracing the predefined meta-paths. GraphRet helps enrich the seed symptom set through the EHR graph when confronting users with scarce descriptions, hence yield better diagnosis accuracy. At last, we validate the superiority of our model on a large-scale EHR dataset.

description: We study an interacting composite $(1+1/n)$ Abelian helical edge state made of a regular helical liquid carrying charge $e$ and a (fractionalized) helical liquid carrying charge $e/n$. A systematic framework is developed for these composite $(1+1/n)$ Abelian helical edge states with $n=1,2,3$. For $n=2$, the composite edge state consists of a regular helical Luttinger liquid and a fractional topological insulator (the Abelian $Z_4$ topological order) edge state arising from half-filled conjugated Chern bands. The composite edge state with $n=2$ is pertinent to the recent twisted MoTe$_2$ experiment, suggesting a possible fractional topological insulator with conductance $\frac{3}{2}\frac{e^2}{h}$ per edge. Using bosonization, we construct generic phase diagrams in the presence of $weak$ Rashba spin-orbit coupling. In addition to a phase of free bosons, we find a time-reversal symmetry-breaking localized insulator, two perfect positive drag phases, a perfect negative drag phase (for $n=2,3$), a time-reversal symmetric Anderson localization (only for $n=1$), and a disorder-dominated metallic phase analogous to the $ν=2/3$ disordered fractional quantum Hall edges (only for $n=3$). We further compute the two-terminal edge-state conductance, the primary experimental characterization for the (fractional) topological insulator. Remarkably, the negative drag phase gives rise to an unusual edge-state conductance, $(1-1/n)\frac{e^2}{h}$, not directly associated with the filling factor. We further investigate the effect of an applied in-plane magnetic field. For $n>1$, the applied magnetic field can result in a phase with edge-state conductance $\frac{1}{n}\frac{e^2}{h}$, providing another testable signature. Our work establishes a systematic understanding of the composite $(1+1/n)$ Abelian helical edge, paving the way for future experimental and theoretical studies.

description: We perform an extensive study of numerical convergence for hot-Jupiter atmospheric flow solutions in simulations employing a setup commonly-used in extrasolar planet studies, a resting state thermally forced to a prescribed temperature distribution on a short time-scale at high altitudes. Convergence is assessed rigorously with: (i) a highly-accurate pseudospectral model which has been explicitly verified to perform well under hot-Jupiter flow conditions and (ii) comparisons of the kinetic energy spectra, instantaneous (unaveraged) vorticity fields and temporal evolutions of the vorticity field from simulations which are numerically equatable. In the simulations, the (horizontal and vertical) resolutions, dissipation operator order and viscosity coefficient are varied with identical physical and initial setups. All of the simulations are compared against a fiducial, reference simulation at high horizontal resolution and dissipation order (T682 and $\nabla^{16}$, respectively) -- as well as against each other. Broadly, the reference solution features a dynamic, zonally (east-west) asymmetric jet with a copious amount of small-scale vortices and gravity waves. Here we show that simulations converge to the reference simulation only at T341 resolution and with $\nabla^{16}$ dissipation order. Below this resolution and order, simulations either do not converge or converge to unphysical solutions. The general convergence behaviour is independent of the vertical range of the atmosphere modelled, from $\sim\! 2\!\times\! 10^{-3}$ MPa to $\sim\! 2\!\times\! 10^1$ MPa. Ramifications for current extrasolar planet atmosphere modelling and observations are discussed.

description: Multiple populations (MPs) in globular clusters (GCs) are stars distinct by their abundances of light elements. The MPs can be directly separated by measuring abundances of C, N, O, Na, Al, Mg with spectroscopy or indirectly from photometric sequences created by the impact of different chemistry on band passes of particular filters, such as the HST pseudo-colours in the ultraviolet. An attempt to link HST pseudo-colours maps (PCMs) and spectroscopy was done by Marino et al. (2019), using abundances mostly from our FLAMES survey. However, we uncovered that an incomplete census of stars in common was used in their population tagging. We correct the situation by building our own PCMs and matching them with our abundances in 20 GCs, plus two GCs from other sources, doubling the sample with spectroscopic abundances available. We found that the pseudo-colour (magF275W-2*magF336W+magF438W) does not have a monotonic trend with Na abundances, enhanced by proton-capture reactions in MPs. Moreover, on average about 16% of stars with spectroscopic Na abundances show a discrepant tagging of MPs with respect to the HST photometry. Stars with chemistry of second generation (SG) are mistaken for first generation (FG) objects according to HST photometry and vice versa. In general, photometric indices tend to overestimate the fraction of FG stars, in particular in low mass GCs. We offer a simple explanation for these findings. Finally, we publish all our PCMs, with more than 31,800 stars in 22 GCs, with star ID and coordinates, for easy check and reproduction, as it should be in science papers.

description: The transformations taking place in late-type galaxies in the environment of rich clusters of galaxies at z=0 are reviewed. From the handful of late-type galaxies that inhabit local clusters, whether they were formed in-situ and survived as such, avoiding transformation or even destruction or if they are newcomers that recently infall from outside, we can learn an important lesson on the latest stages of galaxy evolution. We start by reviewing the observational scenario, covering the broadest possible stretch of the electromagnetic spectrum, from the gas tracers, the star formation tracers, the old star tracers and the dust. Strong emphasis is given to the three nearby, well studied clusters Virgo, A1367 and Coma, representative of different evolutionary stages, from unrelaxed, spiral rich (Virgo) to relaxed, spiral poor clusters (Coma). We continue by providing a review of models of galaxy interactions relevant to clusters of galaxies. Prototypes of various mechanisms and processes are discussed and their typical time-scales are given in an Appendix. Observations indicate the presence of healthy late-type galaxies falling into nearby clusters individually or belonging to massive groups. More rare are infalling galaxies belonging to compact groups where significant pre-processing might take place. Once entered the cluster, they loose their gas and quench their star formation activity, becoming anemics. Observations and theory agree in indicating that the interaction with the intergalactic medium is responsible for the gas depletion. This process, however, cannot be at the origin of the cluster lenticular galaxy population. Physical and statistical properties of S0 in nearby clusters and at higher redshift, indicate that they originate from spiral galaxies transformed by gravitational interactions.

description: The threat of bush encroachment on community livelihoods and economy in range lands of Fentale district in Ethiopia is not well known. So, this study was conducted to evaluate the impact of bush encroachment and its stress on livestock daily milk yield and pastoral livestock production of the district. The data of household livestock holding and its production, household income sources, expenditure, etc. was obtained from district pastoral and agro-pastoral office and the respective pastoral communities. The data was collected through semi-structured questionnaires, focus group discussion and key informant interviews. The data was analyzed through descriptive statistics and regression analysis using Minitab Software. The result revealed that there was an alarming rate increasing of bush encroachment coverage and positive association (P < 0.05) with camel and goat population than cattle and sheep population (P > 0.05) in the study district. Results of current study also revealed that a positive correlation between increasing coverage of bush encroachment and mean daily milk yield of livestock (i.e. cattle, goat and camel) in the study areas. Pastoral producers also perceived the impact of bush encroachment on livestock population trend and milk production in all study sites and applied different adaptation strategies (like feed supplementation and mobility). It is recommended that appropriate intervention options (like bush thinning) of government and other stakeholders is needed to alleviate the current economic bush related challenges of pastoral producers and save the loosing natural resources, even by amendment of pastoral production related policies and its implementation

description: The citrus fruit production has rapidly increased both in the world and in Turkey. The EU holds a big place in Turkey's citrus fruit export. The relations between the EU and Turkey also play a considerably significant role for the citrus trade. It is crucial to examine the factors affecting Turkey's citrus export, together with determining how the structure of Turkey's citrus export towards the EU will form. Three main problems of Turkey's citrus export can be described. These are the lack of product quality demanded by standards and consumers, the absence of product variety demanded in the EUmarkets, and the existence of competing countries. However, having a good taste in citrus fruit and short distance between the EU and Turkey can be considered as the advantages from the point of Turkey's export. It is clear that changes in the EU necessitate a well-directed production. From this viewpoint, the most important issue is the perspective of how to construct a successful exportation, by starting with a directed production according to changes in the EU. So, the main objective of this research is to examine Turkey's citrus export towards the EU and to determine advantages and disadvantages that Turkey may face regarding its adaptation process and its probable membership in the EU.

description: Successful robotic operation in stochastic environments relies on accurate characterization of the underlying probability distributions, yet this is often imperfect due to limited knowledge. This work presents a control algorithm that is capable of handling such distributional mismatches. Specifically, we propose a novel nonlinear MPC for distributionally robust control, which plans locally optimal feedback policies against a worst-case distribution within a given KL divergence bound from a Gaussian distribution. Leveraging mathematical equivalence between distributionally robust control and risk-sensitive optimal control, our framework also provides an algorithm to dynamically adjust the risk-sensitivity level online for risk-sensitive control. The benefits of the distributional robustness as well as the automatic risk-sensitivity adjustment are demonstrated in a dynamic collision avoidance scenario where the predictive distribution of human motion is erroneous.

description: We show how to efficiently sample the joint posterior of two non-covariant experiments with a large set of nuisance parameters. Specifically, we train an ensemble of normalizing flows to learn the posterior distribution of both experiments. Once trained, we can use the flows to reweight $\mathcal{O} (10^9)$ samples from both measurements to compute the joint posterior in seconds -- saving up to $\mathcal{O}(1)$ ton of $\text{CO}_2$ per Monte Carlo run. Using this new technique we find joint constraints between the Dark Energy Survey $3 \times 2$ point measurement, South Pole Telescope and Planck CMB lensing and a BOSS direct fit full shape analyses, for the first time. We find $Ω_{\rm m} = 0.32^{+0.01}_{-0.01}$ and $S_8 = 0.79 ^ {+0.01}_ {-0.01}$. We release a public package called {\tt CombineHarvesterFlow} (https://github.com/pltaylor16/CombineHarvesterFlow) which performs these calculations.

description: The recent COVID-19 pandemic has become a major threat to human health and well-being. Non-pharmaceutical interventions such as contact tracing solutions are important to contain the spreads of COVID-19-like infectious diseases. However, current contact tracing solutions are fragmented with limited use of sensing technologies and centered on monitoring the interactions between individuals without an analytical framework for evaluating effectiveness. Therefore, we need to first explore generic architecture for contact tracing in the context of today's Internet of Things (IoT) technologies based on a broad range of applicable sensors. A new architecture for IoT based solutions to contact tracing is proposed and its overall effectiveness for disease containment is analyzed based on the traditional epidemiological models with the simulation results. The proposed work aims to provide a framework for assisting future designs and evaluation of IoT-based contact tracing solutions and to enable data-driven collective efforts on combating current and future infectious diseases.

The experimental design used was randomized complete block design with four replications per treatment, under the arrangement of subdivided plots, in which three corn hybrids were assigned to complete plots and four inoculant-N fertilization treatments, to the subplots. The results showed that for dose fertilization of 180 kg ha-1 of nitrogen (control), the grain yield of hybrid corn was similar as compared to 60-120 kg ha-1 N fertilization inoculated at 15 and 45 days with a native strain of Azospirillum sp., suggesting that the response in grain yield for hybrid corn can be balanced with nitrogen fertilization and inoculation with Azospirillum sp. 1x108 CFU mL-1 in conditions of arid soils, with possible impact on the use of this microorganism in the maize production system

description: Conventional algorithms for galaxy power spectrum estimation measure the true spectrum convolved with a survey window function, which, for parameter inference, must be compared with a similarly convolved theory model. In this work, we directly estimate the unwindowed power spectrum multipoles using quadratic estimators akin to those introduced in the late 1990s. Under Gaussian assumptions, these are optimal and free from the leading-order effects of pixellization and non-Poissonian shot-noise. They may be straightforwardly computed given the survey data-set and a suite of simulations of known cosmology. We implement the pixel-based maximum-likelihood estimator and a simplification based on the FKP weighting scheme, both of which can be computed via FFTs and conjugate gradient descent methods. Furthermore, the estimators allow direct computation of spectrum coefficients in an arbitrary linear compression scheme, without needing to first bin the statistic. Applying the technique to a subset of the BOSS DR12 galaxies, we find that the pixel-based quadratic estimators give statistically consistent power spectra, compressed coefficients, and cosmological parameters to those obtained with the usual windowed approaches. Due to the sample's low number density and compact window function, the optimal weighting scheme gives little improvement over the simplified form; this may change for dense surveys or those focusing on primordial non-Gaussianity. The technique is shown to be efficient and robust, and shows significant potential for measuring the windowless power spectrum and bispectrum in the presence of weak non-Gaussianity.

description: The research focused on two production systems of fattening pigs : conventional system (housing on cross - barred floor) and ecological system (housing on deep litter). Favorable climatic conditions for pig meat production, possibilities to produce cheaper food of better quality and great amounts of litter, are a good basis for making ecological pig production widely accepted by family farms. Ecological aspect of such production of pigs, along with its economic analysis will be key factors, which will influence pig producers in their choice of the most suitable technological solution. In comparison to the conventional way of keeping pigs, main advantages of pig housing on deep litter are cheaper building and equipping of pens, better effect on health conditions of pigs, as well as easier manipulating with manure. Following this context, the research objective was to analyze economic indicators of different pig production systems and to compare economic results obtained in conventional and ecological way of pig production. The research aim was to determine economic possibilities and to evaluate results of production systems in question, justifying their economic and social aspects.

description: Настоящая статья рассматривает с точки зрения работы эксперта-лингвиста новую формулировку статьи Кодекса об административных правонарушениях, регулирующей ответственность за оскорбление личности. Новая формулировка рассматривается в связи с понятием «неприличной формы», дискуссии о котором ведутся в сообществе лингвистов и экспертов вот уже почти 25 лет. По мнению автора статьи, юридическая новелла, о которой идет речь, не затронет перечень слов и выражений, которые традиционно относятся к оскорбительным, однако заставит экспертов внимательнее относиться к оценке свойств коммуникативной ситуации, в которой подобные  высказывания осуществляются, и контексту их употребления. Автор статьи исходит в своих рассуждениях из представлений о том, что лингвистическая экспертиза прежде всего должна оцениваться по ее эффективности и объективности оценки предложенной ситуации.

description: Research on consumer behaviour has revealed that the prospect of reaching a personal value is the virtual buying motive. Bearing this in mind, the researcher, as well as the marketer, is not only able to observe whether one product is preferred to another, but also to understand why this product is preferred. Hence, identifying consumers' personal values contributes to explaining consumer preferences and buying motives, which is of great importance for marketing practice. Personal values that are developed during the process of socialisation are part of a culture and differ depending on one's cultural background. Therefore, culture- specific values result in specific consumer behaviour. The aim of our paper is to combine research about buying motives (generally speaking, consumers' personal values) and about culture- specific consumption patterns. Knowledge of these cohesions is of great importance for marketing strategies. If there are differences between the personal values of consumers who are from different cultural backgrounds, this has to be taken into account by differentiating the strategic direction of marketing strategies, which should incorporate culture- specific product cognition. The following aspects of this issue will be discussed in the paper: · consumers buy products because of the resulting consequences, which satisfy consumer values · values are part of the culture, and therefore cause culture- specific consumer behaviour · the underlying motives for culture- specific consumer behaviour have to be included in marketing strategies.

description: In this work it explains the actual situation of organic production and marketing in Spain, studying and analyzing their evolution in the last decade of anterior century and in the first years of the new millennium. In Spain, organic production began in 70's with pioneers in Catalonia, Murcia Region and other zones. It was in 90's when it was observed a great increase in organic surfaces. A very interesting and critic date is that at the moment, more of 80% of organic products it is exporting to other European countries, USA and others foreign markets, and it is necessary a new marketing strategies and innovations to structure the organic market, give a new information to consumers, improve the investment in relation between retailers and this consumers, and improve the perception of utilities of this products. In some countries as is the case of Spain, the consumer s don't have enough information about the characteristics of organic products, organic food and organic production methodologies. They must to know all information along the benefits of organic production methodologies and their implications in environment conservation, biodiversity protection, food quality and safety, and this task must be provided by the new marketing strategies and actions.
Stretching the Horizon of a Higher Dimensional Small Black Hole

description: There is a general scaling argument that shows that the entropy of a small black hole, representing a half-BPS excitation of an elementary heterotic string in any dimension, agrees with the statistical entropy up to an overall numerical factor. We propose that for suitable choice of field variables the near horizon geometry of the black hole in D space-time dimensions takes the form of AdS_2\times S^{D-2} and demonstrate how this ansatz can be used to calculate the numerical factor in the expression for the black hole entropy if we know the higher derivative corrections to the action. We illustrate this by computing the entropy of these black holes in a theory where we modify the supergravity action by adding the Gauss-Bonnet term. The black hole entropy computed this way is finite and has the right dependence on the charges in accordance with the general scaling argument, but the overall numerical factor does not agree with that computed from the statistical entropy except for D=4 and D=5. This is not surprising in view of the fact that we do not use a fully supersymmetric action in our analysis; however this analysis demonstrates that higher derivative corrections are capable of stretching the horizon of a small black hole in arbitrary dimensions.

description: Grand canonical simulations designed to resolve critical universality classes are reported for $z$:1 hard-core electrolyte models with diameter ratios $λ{=} a_+/a_- {\lesssim} 6$. For $z {=} 1$ Ising-type behavior prevails. Unbiased estimates of $T_c(λ)$ are within 1% of previous (biased) estimates but the critical densities are $\sim $5 % lower. Ising character is also established for the 2:1 and 3:1 equisized models, along with critical amplitudes and improved $T_c$ estimates. For $z {=} 3$, however, strong finite-size effects reduce the confidence level although classical and O$(n {\geq} 3)$ criticality are excluded.

description: Core-collapse supernovae (SNe) are the inevitable fate of most massive stars. Since most stars form in groups, SN progenitors can be constrained with information of their environments. It remains challenging to accurately analyse the various components in the environment and to correctly identify their relationships with the SN progenitors. Using a combined dataset of VLT/MUSE spatially-resolved integral-field-unit (IFU) spectroscopy and HST/ACS+WFC3 high-spatial resolution imaging, we present a detailed investigation of the environment of the Type II-P SN 2004dg and Type IIb SN 2012P. The two SNe occurred in a spiral arm of NGC 5806, where a star-forming complex is apparent with a giant H II region. By modelling the ionised gas, a compact star cluster and the resolved stars, we derive the ages and extinctions of stellar populations in the vicinity of the SNe. The various components are consistent with a sequence of triggered star formation as the spiral density wave swept through their positions. For SNe 2004dg and 2012P, we identify their host stellar populations and derive initial masses of $10.0^{+0.3}_{-0.2}~M_\odot$ and $15.2^{+2.0}_{-1.0}~M_\odot$ for their progenitors, respectively. Both results are consistent with those from pre-explosion images or nebular-phase spectroscopy. SN 2012P is spatially coincident but less likely to be coeval with the star-forming complex. As in this case, star formation bursts on small scales may appear correlated if they are controlled by any physical processes on larger scales; this may lead to a high probability of chance alignment between older SN progenitors and younger stellar populations.
