description: Energetic flares and associated coronal mass ejections (CMEs) from young magnetically active solar-like stars can play a critical role in setting conditions for atmospheric escape as well aspenetration of accelerated particles into their atmospheres that promotes formation of biologically relevant molecules. We have used the observationally reconstructed magnetic field of the 0.7 Gyr-young Suns twin, k1 Ceti, to study the effects of CME deflections in the magnetic corona of the young Sun and their effects on the impact frequency on the early Venus, Earth and Mars. We find that the coronal magnetic field deflects the CMEs toward the astrospheric current sheet (ACS). This effect suggests that CMEs tend to propagate within a small cone about the ecliptic plane increasing the impact frequency of CMEs with planetary magnetospheres near this plane to ~ 30 percent or by a factor of 6 as compared to previous estimate by Airapetian et al. 2016. Our model has important implications for the rise of prebiotic chemistry on early terrestrial planets as well as terrestrial type exoplanets around young G-K dwarfs.

description: We investigate the equilibrium and out-of-equilibrium Kondo effects in a single-level interacting quantum dot connected to two ferromagnetic leads. Within the non-crossing approximation, we calculate the total density of states (DOS), the linear conductance, and the nonlinear differential conductance for both the parallel and the anti-parallel alignments of the spin polarization orientation in the leads, followed by a brief discussion regarding the validity of this approach. Numerical calculations show that for the anti-parallel alignment, a single Kondo peak always appears in the equilibrium DOS, resulting in the conventional temperature behavior in the linear conductance and the zero-bias maximum in the differential conductance. The strength of the DOS peak is gradually suppressed with increasing polarization, due to the fact that formation of the Kondo-correlated state is more difficult in the presence of higher polarization. On the contrary, for the parallel configuration the Kondo peak in the DOS descends precipitately and splits into two peaks to form a very steep valley between them. This splitting contributes to the appearance of a "hump" in the temperature-dependent linear conductance and a nonzero-bias maximum in the differential conductance. Moreover, application of a bias voltage can split each Kondo peak into two in the nonequilibrium DOS for both configurations. Finally we point out that the tunnel magnetoresistance could be an effective tool to demonstrate the different Kondo effects in different spin configurations found here.

description: In experiments on electron transport the macroscopic inhomogeneities in the sample play a fundamental role. In this paper and a subsequent one we introduce and develop a general formalism that captures the principal features of sample inhomogeneities (density gradients, contact misalignments) in the magneto resistance data taken from low mobility heterostructures. We present detailed assessments and experimental investigations of the different regimes of physical interest, notably the regime of semiclassical transport at weak magnetic fields, the plateau-plateau transitions as well as the plateau-insulator transition that generally occurs at much stronger values of the external field only. It is shown that the semiclassical regime at weak fields plays an integral role in the general understanding of the experiments on the quantum Hall regime. The results of this paper clearly indicate that the plateau-plateau transitions, unlike the the plateau-insulator transition, are fundamentally affected by the presence of sample inhomogeneities. We propose a universal scaling result for the magneto resistance parameters. This result facilitates, amongst many other things, a detailed understanding of the difficulties associated with the experimental methodology of H.P. Wei et.al in extracting the quantum critical behavior of the electron gas from the transport measurements conducted on the plateau-plateau transitions.

description: Despite growing interest in biomass over the last number of years, bio-energy derived from biomass currently contributes to a very small share of the total Spanish energy market. How individual farmers choose to respond to the opportunities presented by these relatively novel crops has still received scarce attention. In this paper, farmers’intentions towards the adoption of energy crops are analyzed. A survey of 201 farmhouseholds in Southern Spain is explored using a non-parametric approach based on classification tree algorithms. The main outcome of this analysis is that off-farm labour factor affects the adoption of energy crops on farm, together with farm specializations, size of owned land and farmer’s education. While the study confirms the relevance of the main determinants available from the literature, need for further research is emphasised.

description: It has recently been observed that the normalization of a one-dimensional out-of-equilibrium model, the Asymmetric Exclusion Process (ASEP) with random sequential dynamics, is exactly equivalent to the partition function of a two-dimensional lattice path model of one-transit walks, or equivalently Dyck paths. This explains the applicability of the Lee-Yang theory of partition function zeros to the ASEP normalization. In this paper we consider the exact solution of the parallel-update ASEP, a special case of the Nagel-Schreckenberg model for traffic flow, in which the ASEP phase transitions can be intepreted as jamming transitions, and find that Lee-Yang theory still applies. We show that the parallel-update ASEP normalization can be expressed as one of several equivalent two-dimensional lattice path problems involving weighted Dyck or Motzkin paths. We introduce the notion of thermodynamic equivalence for such paths and show that the robustness of the general form of the ASEP phase diagram under various update dynamics is a consequence of this thermodynamic equivalence.

Depending on the gap topology and relative field direction the field dependencies of ZEDOS sensitively differ, providing us a useful and practical method to identify the gap topology. It is also demonstrated that for d-wave state the field rotation in the basal plane shows a sizable oscillation ~3% of ZEDOS. This is directly measurable in low-T specific heat experiment in the mixed state.

description: This study analyses European consumers’ awareness and determinants of use of PDO, PGI and TSG labels in six European countries (Italy, Spain, France, Belgium, Norway and Poland) using data from a cross-sectional survey with 4,828 participants. The study confirms a higher awareness of PDO (68.1%) as compared to PGI (36.4%) and TSG (25.2%). Awareness is higher among men and people aged above 50 years. Consumers’ use of a PDO, PGI or TSG label is triggered by the belief that the label signals better product quality. Quality beliefs are shaped by an interest in getting information about product quality through the quality label. Interest in the origin of foods is a stronger direct and indirect driver of label use than interest in support for the local economy, but both motivations are not directly related to TSG-label use. Differences in the role of determinants are small between the three labelling schemes and between countries with versus without a strong tradition of quality labels in their agricultural and food quality policies. Apart from building general awareness and favourable quality perceptions of the quality schemes and their respective labels, efforts to stimulate consumers’ interest in origin and getting information about product quality through EU quality labels are recommended.

description: The SA government has favored cooperatives over other types of corporate entities in its programmes for rural development. This study examines financial efficiency and its determinants for 387 agricultural cooperatives in SA using a two-stage double bootstrap approach. Bias-corrected Data Envelopment Analysis (DEA) efficiency estimates are obtained in the first-stage for the agricultural cooperatives. Next, a Double Bootstrapped Truncated Regression model was estimated to obtain bias-corrected scores. The model was designed to obtain DEA scores for financial efficiency. First-stage results indicate that many agricultural cooperatives are relatively inefficient. Results of the second-stage analysis identified significant determinants of efficiency as age of cooperatives, size, gender of management, governance indicators and training. Governance indicators negatively influencing efficiency indicate institutions that prioritize non-financial goals and consequently compromise on governance quality. The deviation from institutional control mechanisms most likely emerges in a weak institutional environment. Various types of training influenced financial efficiency meaning that an understanding of training needs across institutions is crucial for equipping and empowering cooperatives towards financial efficiency. The study shows that the design and implementation of suitable training programs are prerequisites for addressing financial efficiency of agricultural cooperatives.

description: We define a new multispecies model of Calogero type in D dimensions with harmonic, two-body and three-body interactions. Using the underlying conformal SU(1,1) algebra, we indicate how to find the complete set of the states in Bargmann-Fock space. There are towers of states, with equidistant energy spectra in each tower. We explicitely construct all polynomial eigenstates, namely the center-of-mass states and global dilatation modes, and find their corresponding eigenenergies. We also construct ladder operators for these global collective states. Analysing corresponding Fock space, we detect the universal critical point at which the model exhibits singular behavior. The above results are universal for all systems with underlying conformal SU(1,1) symmetry.

description: Peri-urban agriculture presents an opportunity as a livelihood strategy to alleviate poverty and ensure household food security. However, little is still known on the contribution of peri-urban agriculture towards household food security. The current study assessed the contribution of peri-urban agriculture on household food security in Tongaat peri-urban area. Using a stratified random sampling procedure, 208 households (that is 109 farming and 99 non-farming households) were selected. Descriptive statistics were used to describe household socio-economic characteristics. The Household Dietary Diversity Score (HDDS) and Household Food Insecurity Access Score (HFIAS) measures were employed to estimate a household food security status. The HDDS tool showed that a greater proportion (54%) � farming households consumed >6 food groups as compared to their counterparts, the non-farming households (40%) in the same food group. the HFIAS measure revealed that a greater proportion (about 72%) of the farming households indicated that they never or rarely worried about food shortages as compared to their counterparts � the non-farming households (about 61%) that never or rarely worried about food shortages. Overall results suggest that farming households were better-off in terms of food access and dietary requirements than non-farming households. Peri-urban agriculture if promoted can help households achieve food security. Keywords: Households, Household dietary diversity score, Household food insecurity access scale, household food security, peri-urban agriculture, Tongaat.

description: Well studied Open Clusters (OCs) in the Solar neighbourhood are used as reference objects to test galactic and stellar theories. For that purpose their chemical composition needs to be known with a high level of confidence. The aims of this work are (1) to determine accurate and precise abundances of 22 chemical species (from Na to Eu) in the Hyades, Praesepe and Rupecht 147 using a large number of stars at different evolutionary states, (2) to evaluate the level of chemical homogeneity of these OCs, (3) to compare their chemical signatures. We gathered $\sim$800 high resolution and high S/N spectra of $\sim$100 members in the three OCs, obtained with the latest memberships based on Gaia DR2 data. We build a pipeline which computes atmospheric parameters and strictly line-by-line differential abundances among twin stars in our sample, which allows us to reach a very high precision in the abundances (0.01-0.02 dex in most of the elements). We find large differences in the absolute abundances in some elements, which can be attributed to diffusion, NLTE effects or systematics in the analysis. For the three OCs, we find strong correlations in the differential abundances between different pairs of elements, which can be explained by some level of chemical inhomogeneity. We compare differential abundances of several stars from the Hyades and Praesepe tails: the stars that differ more in chemical abundances also have distinct kinematics, even though they have been identified as members of the tail. With this technique we find that the Hyades and Preasepe have the same chemical signature when G dwarfs and K giants are considered. Despite a certain level of inhomogeneity in each cluster, it is still possible to clearly distinguish the chemical signature of the older cluster Ruprecht~147 when compared to the others.

Cosmic rays, stellar evolution, and supernova physics

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Most cosmic rays are thought to be accelerated by the shocks of supernova explosions of very massive stars. Here we review one quantitative proposal, which predicted the spectral slopes, bend and cutoff about the cosmic ray spectrum across the spectral bend or "knee" near 3x10^15 eV in 1993. Many of the specific predictions have now been verified, and so it may be appropiate to investigate the consequences of that proposal. The successful fit to the cosmic ray data across the knee suggests: 1) very massive stars, above about 20 to 25 solar masses all converge to a common final state; 2) the supernova explosion of these very massive stars is caused by a combination of rotation, magnetic fields and the gravitational potential, just as proposed by G. Bisnovatyi-Kogan in 1970, based on an earlier suggestion by N.S. Kardashev in 1964; 3) their stellar winds as well as the explosion provide the main injection of magnetic fields into the interstellar medium; 4) the explosive energy of these supernovae is about 10^52 erg; 5) the explosion is extremely anisotropic, which may unify several classes of observed supernova types; 6) gamma ray bursts may be the ultimate version of such an explosion in the case the collapse leads to a black hole; 7)it is plausible that the luminosity of the supernova integrated over all aspect angles is also the same for all these massive star explosions, leading to 8) a possibly very bright standard candle, if we could just find a correction for the extreme asphericity. This may solve the problem of what the mechanism of supernova explosions is for very massive stars, where most cosmic rays and magnetic fields come from, and may also point the way to a unifying scheme for supernova explosions and gamma ray bursts.

description: This research investigated the timing of marketing decisions in the Canadian wheat market. Cox proportional hazard models were estimated to explore how the timing of producers’ decisions were affected by market-based variable, which included an indicator showing whether current prices were above producers’ benchmark on a given day, 10-day average spread between current prices and producers’ benchmark, 10-day price trend and price volatility over 10 days. Marketing data for 17,338 producers who executed 59,184 transactions between 2003/04 and 2008/09 were used in the analysis. Overall results indicate that all variables affected timing decisions in producers’ marketing choices. However, the signs of the estimated coefficients tended to vary across contracts and years, suggesting that producers could change their pricing behavior over time and response to the covariates could also depend on characteristics of the contracts and how they relate to producers’ marketing strategies.

description: Understanding the subgraph distribution in random networks is important for modelling complex systems. In classic Erdos networks, which exhibit a Poissonian degree distribution, the number of appearances of a subgraph G with n nodes and g edges scales with network size as \mean{G} ~ N^{n-g}. However, many natural networks have a non-Poissonian degree distribution. Here we present approximate equations for the average number of subgraphs in an ensemble of random sparse directed networks, characterized by an arbitrary degree sequence. We find new scaling rules for the commonly occurring case of directed scale-free networks, in which the outgoing degree distribution scales as P(k) ~ k^{-γ}. Considering the power exponent of the degree distribution, γ, as a control parameter, we show that random networks exhibit transitions between three regimes. In each regime the subgraph number of appearances follows a different scaling law, \mean{G} ~ N^α, where α=n-g+s-1 for γ<2, α=n-g+s+1-γfor 2γ_c, s is the maximal outdegree in the subgraph, and γ_c=s+1. We find that certain subgraphs appear much more frequently than in Erdos networks. These results are in very good agreement with numerical simulations. This has implications for detecting network motifs, subgraphs that occur in natural networks significantly more than in their randomized counterparts.

description: Given an integer partition $(h_1,h_2,\dots,h_k)$ of $n$, is it possible to find an order $n$ latin square with $k$ disjoint subsquares of orders $h_1,\dots,h_k$? This question was posed by L.Fuchs and is only partially solved. Existence has been determined in general when $k\leq 4$, and in this paper we will complete the case when $k=5$. We also prove some less general results for partitions with $k=5$.

description: This study provides a systematic empirical investigation of lead-lag relationships among trading positions and prices in commodity futures markets. It employs Toda-Yamamoto Granger-causality tests applied on a variety of measurements of hedging, speculative, and index trader position activities and futures prices. Weekly futures market positions from the Commodity Futures Trading Commission (CFTC) and prices are examined for 24 commodities (1995 to 2011) based on Commitments of Traders (COT) reports and twelve commodities (2006 to 2011) based on Commodity Index Trader Supplement (CIT) reports. In particular, this study empirically examines whether pressures on prices due to hedging and speculative activities can be identified, and whether they have changed due to structural changes in commodity futures markets. Results suggest little systematic lead-lag relationship from hedging and speculative activities to prices. In contrast, there is strong evidence that prices tend to lead traders’ hedging and speculative activity. These results appear to be generally persistent over commodities, measurements of hedging and speculation, and periods. In summary, hedging and speculative pressures may not be helpful in explaining prices in commodity futures markets; to the contrary, prices may cause traders to change their positions.

description: The stable boundary layer (SBL) subjected to large-scale subsidence is studied through large-eddy simulations (LESs) with fixed surface temperature and a linear subsidence velocity profile. These boundary layers reach a truly steady state, where thermal equilibrium is established by a balance between surface cooling and subsidence-induced heating. We identify three governing dimensionless groups by scaling the governing equations with the geostrophic wind and Coriolis frequency, and systematically investigate the impact of these external parameters on global flow properties and mean profiles in the steady state. The SBL depth, low-level jet, and the magnitude of the turbulent momentum flux are reduced when the subsidence rate or Buoyancy number increases, while surface heat flux is enhanced. The shape of normalized mean profiles of temperature and heat flux is mainly determined by the subsidence rate, while they collapse for varying buoyancy and surface Rossby numbers. We develop empirical correlations for the stability parameter $h_θ/L_O$ and a thermal shape factor, and propose a new unidirectional geostrophic drag law, to form a closed set of equations that estimates relevant flow properties from external parameters. The estimation errors compared to the LES data are less than 5% for friction velocity and surface heat flux, and at most 10% for the SBL depth $h_θ$. Within the surface layer, dimensionless velocity and temperature gradients in the steady SBL with subsidence show acceptable agreement to Monin-Obukhov similarity theory, while the collapse is improved when a recently proposed mixed scaling parameter, that includes $h_θ/L_O$, is used.

description: We study a one-dimensional model with F interacting families of Calogero-type particles. The model includes harmonic, two-body and three-body interactions. We emphasize the universal SU(1,1) structure of the model. We show how SU(1,1) generators for the whole system are composed of SU(1,1) generators of arbitrary subsystems. We find the exact eigenenergies corresponding to a class of the exact eigenstates of the F-family model. By imposing the conditions for the absence of the three-body interaction, we find certain relations between the coupling constants. Finally, we establish some relations of equivalence between two systems containing F families of Calogero-type particles.

description: Vertical packaging of multiple Giant Magnetoresistance (multi-GMR) stacks is a very interesting noise reduction strategy for local magnetic sensor measurements, which has not been reported experimentally so far. Here, we have fabricated multi-GMR sensors (up to 12 repetitions) keeping good GMR ratio, linearity and low roughness. From magnetotransport measurements, two different resistance responses have been observed with a crossover around 5 GMR repetitions: step-like (N<5) and linear (N>5) behavior, respectively. With the help of micromagnetic simulations, we have analyzed in detail the two main magnetic mechanisms: the Neel coupling distribution induced by the roughness propagation and the additive dipolar coupling between the N free layers. Furthermore we have correlated the dipolar coupling mechanism, controlled by the number of GMRs (N) and lateral dimensions (width), to the sensor performance (sensitivity, noise and detectivity) in good agreement with analytical theory. The noise roughly decreases in multi-GMRs as 1/\sqrt{N} in both regimes (low frequency 1/f and thermal noise). The sensitivity is even stronger reduced, scaling as 1/N, in the strong dipolar regime (narrow devices) while converges to a constant value in the weak dipolar regime (wide devices). Very interestingly, they are more robust against undesirable RTN noise than single GMRs at high voltages and the linearity can be extended towards much larger magnetic field range without dealing with the size and the reduction of GMR ratio. Finally, we have identified the optimal conditions for which multi-GMRs exhibit lower magnetic field detectivity than single GMRs: wide devices operating in the thermal regime where much higher voltage can be applied without generating remarkable magnetic noise.

description: Introdução: A Mobilização Precoce (MP) é a aplicação intensa da reabilitação física dada aos pacientes críticos, que são admitidos na Unidade de Terapia Intensiva (UTI) e normalmente estão confinados ao leito, isso poderia prejudicar a sua mobilidade. Alguns dos efeitos prejudiciais da imobilização são, diminuição da capacidade aeróbica, perda de força óssea e atrofia muscular. A MP inclui atividades como mobilidade no leito, cinesioterapia e atividades funcionais, podendo prevenir a formação de aderências dos tecidos moles aos tecidos circundantes, manter a propriocepção articular e nutrição das cartilagens. Objetivo: O objetivo dopresente trabalho é revisar, por meio da literatura, as abordagens e os efeitos proporcionados pela mobilização precoce nos pacientes submetidos à ventilação mecânica. Metodologia: Trata-se de uma revisão de literatura que se constituiu em8 estudos. A busca foi realizada nas bases de dados Nacional Library of Medicine (PubMed), Physiotherapy Evidence Database (PEDRO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Foram incluídos estudos observacionais, retrospectivo, randomizados, controlados, prospectivos e de coorte que mostram os efeitos da MP em pacientes sob VM. Conclusão: Conclui-se neste estudo que apesar das diferentes abordagens, os efeitos da mobilização na UTI nos pacientes submetidos à VM, são predominantemente benéficos no ganho de força muscular periférica e inspiratória, melhorando a funçãopulmonar. Além disso acelera o processo de recuperação, proporciona maiores taxas de extubação com sucesso, sendo eficaz na diminuição do tempo de ventilação, internação hospitalar e consequentemente, menores custos hospitalares.Palavras Chaves: mobilização precoce, ventilação mecânica e UTI

description: We develop and evaluate quarterly out-of-sample individual and composite density forecasts for U.S. hog prices using data from 1975.I to 2010.IV. Individual forecasts are generated from time series models and the implied distribution of USDA outlook forecasts. Composite density forecasts are constructed using linear and logarithmic combinations, and several straightforward weighting schemes. Density forecasts are evaluated on goodness of fit (calibration) and predictive accuracy (sharpness). Logarithmic combinations using equal and mean square error weights outperform all individual density forecasts and all linear combinations. Comparison of the USDA outlook forecasts to the best logarithmic composite demonstrates the consistent superiority of the composite procedure, and identifies the potential to provide hog producers and market participants with accurate expected price probability distributions that can facilitate decision making.
Random hopping fermions on bipartite lattices: Density of states, inverse participation ratios, and their correlations in a strong disorder regime

description: We study Anderson localization of non-interacting random hopping fermions on bipartite lattices in two dimensions, focusing our attention to strong disorder features of the model. We concentrate ourselves on specific models with a linear dispersion in the vicinity of the band center, which can be described by a Dirac fermion in the continuum limit. Based on the recent renormalization group method developed by Carpentier and Le Doussal for the XY gauge glass model, we calculate the density of states, inverse participation ratios, and their spatial correlations. It turns out that their behavior is quite different from those expected within naive weak disorder approaches.
