description: In order to clarify the influence of (the presence of) the broken time-reversal symmetry state (BTRSS) induced near the interface, tunneling conductance spectra in normal metal / $d_{x^{2}-y^{2}}$-wave superconductor junctions are calculated on the basis of the quasiclassical Green's function method. The spatial dependence of the pair potential in the superconductor side is determined self-consistently. We discuss two types of the symmetry on the BTRSS; i) $d_{x^{2}-y^{2}}$+is-wave state and ii) $d_{x^{2}-y^{2}}$+i$d_{xy}$-wave state. It is shown that the amplitude of the subdominant component (is-wave or i$d_{xy}$-wave) is quite sensitive to the transmission coefficient of the junction. As the results, the splitting of the zero-bias conductance peak due to the BTRSS inducement is detectable only at junctions with small transmission coefficients for both cases. When the transmission coefficients are relatively large, the explicit peak splitting does not occur and the difference in the two cases appears in the height of the zero-bias peaks.

description: Electron-positron momentum densities in Y, reconstructed from two-dimensional angular correlation of annihilation radiation spectra, are compared with the theoretical predictions of fully-relativistic augmented plane-wave calculations. Knowledge of the theoretical densities and of the effects on them of certain symmetry selection rules has allowed us to separate two hole Fermi sur-faces in the third and fourth bands and to establish some Fermi momenta for each of them.

description: We consider criteria for the differentiability of functions with continuous Laplacian on the Sierpinski Gasket and its higher-dimensional variants $SG_N$, $N>3$, proving results that generalize those of Teplyaev. When $SG_N$ is equipped with the standard Dirichlet form and measure $μ$ we show there is a full $μ$-measure set on which continuity of the Laplacian implies existence of the gradient $\nabla u$, and that this set is not all of $SG_N$. We also show there is a class of non-uniform measures on the usual Sierpinski Gasket with the property that continuity of the Laplacian implies the gradient exists and is continuous everywhere, in sharp contrast to the case with the standard measure.

description: We review here the interplay of cluster and galaxy evolution. As a case study, we consider the Butcher-Oemler effect and propose that it is the result of the changing rate of cluster merger events in a hierarchical universe. This case study highlights the need for new catalogs of clusters and groups that possess quantified morphologies. We present such a sample here, namely the Sloan Digital Sky Survey (SDSS) C4 Catalog, which has been objectively-selected from the SDSS spectroscopic galaxy sample. We outline here the C4 algorithm and present first results based on the SDSS Early Data Release, including an X-ray luminosity-velocity dispersion (L_x-sigma) scaling relationship (as a function of cluster morphology), and the density-SFR relation of galaxies within C4 clusters (Gomez et al. 2003). We also discuss the merger of Coma and the NGC4839 group, and its effect on the galaxy populations in these systems. We finish with a brief discussion of a new sample of Hdelta-selected galaxies (i.e., k+a, post--starburst galaxies) obtained from the SDSS spectroscopic survey.

description: A solar jet on 2014 July 31, which was accompanied by a GOES C1.3 flare and a mini-filament eruption at the jet base, was studied by using observations taken by the New Vacuum Solar Telescope and the Solar Dynamic Observatory. Magnetic field extrapolation revealed that the jet was confined in a fan-spine magnetic system that hosts a null point at the height of about 9 Mm from the solar surface. An inner flare ribbon surrounded by an outer circular ribbon and a remote ribbon were observed to be associated with the eruption, in which the inner and remote ribbons respectively located at the footprints of the inner and outer spines, while the circular one manifested the footprint of the fan structure. It is interesting that the circular ribbon's west part showed an interesting round-trip slipping motion, while the inner ribbon and the circular ribbon's east part displayed a northward slipping motion. Our analysis results indicate that the slipping motions of the inner and the circular flare ribbons reflected the slipping magnetic reconnection process in the fan quasi-separatrix layer, while the remote ribbon was associated with the magnetic reconnection at the null point. In addition, the filament eruption was probably triggered by the magnetic cancellation around its south end, which further drove the slipping reconnection in the fan quasi-separatrix layer and the reconnection at the null point.

description: We examine the dynamic inter-dependencies between soybean and majors cereal prices. The importance of this analysis is justified by the high volatility in grain prices and the need to understand how shocks are diffused across markets. We use monthly prices on the international markets of the different grain for a relatively long period from January 1960 to December 2013. The preliminaries analysis of the series show that they are stationary in first difference even in presence of two structural upward shifts in their trend explain the observed persistence of shock in grain markets. Using Johansen cointegration test, we formally test for the co-movement hypothesis and find strong evidence that the grain prices move together pair by pair and as a group. The test confirms the existence of the long run equilibrium relationship among the prices. We find that deviations from the long run equilibrium are large and the corrective adjustment are slow. We also run a causality analysis with an innovation accounting exercise and estimated a dynamic conditional variance and correlation model to understand how and to what extent shocks on one market diffuse to the other markets. We find that there is rich and complex causality links among the grain prices and they volatility. Soybean and wheat as well as maize, individually and together, play a central role in causing the other grain prices. In overall the results show that the grain markets are highly integrated and shocks, on one market, not only accumulate but also diffuse largely and persistently to the other markets. The central role of soybean, wheat and maize suggests that policy to stabilize food prices should focus on these key cereals with the understanding that this may varies according to different country or region.
Hydrodynamic Equations in Quantum Hall Systems at Large Currents

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Hydrodynamic equations (HDEQs) are derived which describe spatio-temporal evolutions of the electron temperature and the chemical potential of two-dimensional systems in strong magnetic fields in states with large diagonal resistivity appearing at the breakdown of the quantum Hall effect. The derivation is based on microscopic electronic processes consisting of drift motions in a slowly-fluctuating potential and scattering processes due to electron-electron and electron-phonon interactions. In contrast with the usual HDEQs, one of the derived HDEQs has a term with an energy flux perpendicular to the electric field due to the drift motions in the magnetic field. As an illustration, the current distribution is calculated using the derived HDEQs.

description: Data challenges are emerging as powerful tools with which to answer fundamental astronomical questions. Time-domain astronomy lends itself to data challenges, particularly in the era of classification and anomaly detection. With improved sensitivity of wide-field surveys in optical and radio wavelengths from surveys like the Large Synoptic Survey Telescope (LSST) and the Canadian Hydrogen Intensity Mapping Experiment (CHIME), we are entering the large-volume era of transient astronomy. I highlight some recent time-domain challenges, with particular focus on the Photometric LSST Astronomical Time series Classification Challenge (PLAsTiCC), and describe metrics used to evaluate the performance of those entering data challenges.

Conformally flat slices of asymptotically flat spacetimes

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: For mathematical convenience initial data sets in numerical relativity are often taken to be conformally flat. Employing the dual-foliation formalism, we investigate the physical consequences of this assumption. Working within a large class of asymptotically flat spacetimes we show that the ADM linear momentum is governed by the leading Lorentz part of a boost even in the presence of supertranslation-like terms. Following up, we find that in spacetimes that are asymptotically flat, and admit spatial slices with vanishing linear momentum that are sufficiently close to conformal flatness, any boosted slice can not be conformally flat. Consequently there are no conformally flat boosted slices of the Schwarzschild spacetime. This confirms the previously anticipated explanation for the presence of junk-radiation in Brandt-Bruegmann puncture data.

description: Recent work has suggested that in highly correlated systems, such as sandpiles, turbulent fluids, ignited trees in forest fires and magnetization in a ferromagnet close to a critical point, the probability distribution of a global quantity (i.e. total energy dissipation, magnetization and so forth) that has been normalized to the first two moments follows a specific non Gaussian curve. This curve follows a form suggested by extremum statistics, which is specified by a single parameter a (a=1 corresponds to the Fisher-Tippett Type I ("Gumbel") distribution.) Here, we present a framework for testing for extremal statistics in a global observable. In any given system, we wish to obtain a in order to distinguish between the different Fisher-Tippett asymptotes, and to compare with the above work. The normalizations of the extremal curves are obtained as a function of a. We find that for realistic ranges of data, the various extremal distributions when normalized to the first two moments are difficult to distinguish. In addition, the convergence to the limiting extremal distributions for finite datasets is both slow and varies with the asymptote. However, when the third moment is expressed as a function of a this is found to be a more sensitive method.

 Ascidia thompsoni Kott 1952, p 312; 1985, p 56 and synonymy.
 Ascidia challengeri: Kott 1985, p 32.
 Distribution
Previously recorded (see Kott 1985): Tasmania (Great Taylor Bay, Port Davey); South Australia (St Vincent Gulf). New records: Tasmania (Port Davey, SAM E2889); Tasmanian Canyons (Pieman Canyon, 472.8 m, QM G308827).
 Description
The newly recorded individuals are 10 and 15 cm long, respectively, narrow anteriorly and increasing to about 4 cm wide posteriorly. The surface is even but rough and the test is firm, even and translucent. The body is laterally flattened. The terminal branchial aperture has about eight lobes and the margin is fringed (although this is obscured in this specimen). The sessile atrial aperture is two-thirds of the body length along the dorsal surface. About 100 long, curved branchial tentacles are crowded around the base of the branchial siphon. The dorsal ganglion can be seen about halfway between the dorsal tubercle (behind the tentacular ring) and the atrial siphon. The slit on the dorsal tubercle is basically U-shaped with the opening directed anteriorly. The horns are turned in or out and sometimes it is interrupted or slightly convoluted and sometimes the dorsal tubercle slit is pulled out into sharp angles (see QM G9325 from St Vincent Gulf and the newly recorded specimen QM G308827). A meshwork of muscles is on the right side of the body. The branchial sac has about six stigmata per mesh. The inside curve of the tight secondary gut loop is swollen with mud. The long stomach with its fine longitudinal fold occupies at least half of the outer (ascending) limb of the primary loop, and is overlaid by this mud-filled portion of the gut. The distal part of the rectum is bent back postero-dorsally to terminate at the base of the short atrial siphon. Shallow lobes are on the anal border. Gonads are usually in the primary loop of the gut, although they appear to be senescent in the large specimen from Pieman Canyon. Small intermediate branchial papillae are only at the junctions of parastigmatal with internal longitudinal vessels.
 Remarks
 The species is distinguished from Ascidia sydneyensis (which has a mud-filled gut and translucent test) by its numerous branchial tentacles, body musculature, the position of the dorsal ganglion and the relatively simple U-shaped slit on the dorsal tubercle, and the postero-dorsal bend of the distal part of the rectum. With the exception of its musculature, these characters distinguish the species from A. saccula n. sp. and the Antarctic A. challengeri Herdman, 1882 (which both have translucent tests and mud-filled gut).

description: How does current weather and climate change impact cropland use and allocation? Using 2010 ARMS data on several thousand central US farms, we estimate a two-step model that controls for expected relative prices, local soil characteristics, and self-selection into primary crop. We find that: (i). early-season and late-season temperatures and rainfall are most significant for selection into corn, while mid-season weather impacts soybean selection; (ii). sensitivity to nonlinear weather effects varies substantially within season and across crops; (iii). soil characteristics are important and should be accounted for in climate studies; and (iv). crop switching may occur under mild climate change.

description: We speculate that the weak gravity conjecture applied to theories with holographic duals bans the existence of disordered phases at zero temperature. We test this idea by introducing a non-zero baryon chemical potential in a deformation of the $SU(N_c)\times SU(N_c)$ Klebanov-Witten gauge theory with broken supersymmetry and conformal invariance. At low temperature, a disordered phase dual to a black brane geometry is unstable for low chemical potentials and metastable for high values. In the metastable phase, states with a partial Higgsing of the gauge group are favored over the normal disordered phase. This is reflected in the properties of the effective potential for color branes in the dual geometry, where the appearance of a global minimum outside the horizon signals the onset of a brane nucleation instability. When the Higgsing involves only one of the group factors, the global minimum remains at a finite distance from the horizon, making it possible to construct holographic duals to metastable "color superconducting" states. We also consider branes dual to excitations with baryon charge, but find that the extremal geometry remains marginally stable against the emission of particles carrying baryon charge independently of the strength of the deformation.

description: Regional employment and population change have displayed considerable spatial disparities within Northern Ireland in recent years. It is important to gain a better understanding of the causes of these spatial disparities to facilitate the development of effective policies to promote economic growth within the rural economy. Growth equilibrium models provide a means to examine the multiple, integrated economic, social and geographical factors that contribute to economic growth and analyse their synergistic effect on each other (Adelaja et al., 2009). This modelling framework has been developed to analyse the interaction of economic phenomena occurring in spatial dimensions and account for interdependencies between population and employment change. This study applies the growth equilibrium model framework to analyse the linkages between population and employment patterns and other exogenous determinants of spatial growth within Northern Ireland. The analysis is based on ward level data over the period 2001 to 2007. The analysis suggests that employment and population growth are interdependent. An increase in population has a positive impact on employment, while an increase in employment has a positive impact on population. Moreover, there is evidence that the spatial spillover effects are significant, indicating that changes in employment/population growth in one region has knock-on impacts on neighbouring regions.

description: We present two-dimensional numerical simulations of the evolution of a low-mass star moving supersonically through its surrounding interstellar medium (ISM). We show that the ejecta of a moving star with a systemic velocity of 20 km/s will interact with the ISM and will form bow-shock structures qualitatively similar to what is observed. We find that, due to ram-pressure stripping, most of the mass ejected during the AGB phase is left downstream of the moving star. As a consequence, the formation of the PN is highly influenced, even at the low relative velocity of the star. The models are based on the predictions of stellar evolution calculations. Therefore, the density and velocity of the AGB and post-AGB winds are time dependent and give rise to the formation of shock regions inside the cavity formed by the previous winds. As a result, the stand-off distance is also time dependent and cannot be determined by simple analytical arguments.

description: For a single crystal of TmGa3, two-dimensional angular correlation of positron annihilation radiation spectra were measured and subjected to a deconvolution algorithm based on the Van Citter iterative method. The three-dimensional electron-positron momentum density was reconstructed both via the Cormack and a modified Fourier-transform-based method. After the 3D LCW transformation, the resulting k-space density was in fair agreement with band structure LMTO calculations. In particular, the use of deconvoluted data helped to reveal small details of the Fermi surface in the 6th band.

description: The Armington procedure (AP) has become increasingly popular in agricultural trade analyses. However, some arguments have arisen concerning the relevance of using the procedure for such analyses. This study examines the assumptions commonly made when using the Armington procedure and suggests modifications for agricultural trade analyses. Results from models utilizing rice-trade data suggest that the assumptions of the single constant elasticity, in particular, may not be appropriate for analyzing agricultural trade. These results also suggest that, with proper modifications, the AP can be applied to agricultural trade. Further, results of a modified Armington procedure indicate that trade in rice exports is highly competitive and that changes in market shares of individual exporters are not independent of changes in budget expenditure allocated to imports.

A comparison of jet-finding algorithms and resolution parameters is presented along with a detailed analysis of basic jet quantities, such as multiplicities and kinematic distributions. A characterization of the energy in the event not associated with a jet is also made. In addition, detector requirements and the effects of realistic detector resolutions are discussed. Finally, an example analysis is presented in which dijets are used to access the gluon helicity contribution to the spin of the proton.

description: A differential cluster variation method (DCVM) is proposed for analysis of spinoidal decomposition in alloys. In this method, lattice symmetry operations in the presence of an infinitesimal composition gradient are utilized to deduce the connection equations for the correlation functions and to reduce the number of independent variables in the cluster variation analysis. Application of the method is made to calculate the gradient energy coefficient in the Cahn-Hilliard free energy function and the fastest growing wavelength for spinodal decomposition in Al-Li alloys. It is shown that the gradient coefficient of congruently ordered Al-Li alloys is much larger than that of the disordered system. In such an alloy system, the calculated fastest growing wavelength is approximately 10 nm, which is an order of magnitude larger than the experimentally observed domain size. This may provide a theoretical explanation why spinodal decomposition after a congruent ordering is dominated by the antiphase boundaries.

description: The aim of the paper is to develop an optimization model to support the analysis of decision-making on Macedonian family farms. Normative linear programming paradigm is applied, utilising its optimization potential. The model is applied on a hypothetical vegetable farm case. The optimal structure in all scenarios indicates that the optimal solution is the production of tomato, pepper, cabbage, carrot and bean. The base scenario reveals a gross margin of 17,924 € which is highest compared to other scenarios. The working capital available is a binding constraint in second and third scenario, where the optimal solution reveals that the land resource is not exhausted. Gross margin sensitivity was examined using the working capital parameterisation. The model is quite flexible thus enabling different crop enterprises to be added additionally.....Cilj ovoga rada jest razvijanje modela optimiranja kako bi se pružila potpora analizi donošenja odluka na makedonskim obiteljskim farmama. Primijenjen je normativni obrazac linearnog programiranja, pri čemu se koristio njegov potencijal optimiranja. Model je primjenjen na hipotetski slučaj farme za proizvodnju povrća. Optimalna struktura, prema svim scenarijima, ukazuje da je optimalno rješenje proizvodnja rajčice, paprike, kupusa, mrkve i graha. Osnovni scenarij ukazuje da je bruto marža od 17,924 € najviša u odnosu na ostale scenarije. Postojeći obrtni kapital obvezujuće je ograničenje u drugom i trećem scenariju, u kojima optimalno rješenje ukazuje da zemljišni resursi nisu iscrpljeni. Osjetljivost na bruto maržu ispitivala se parametrizacijom obrtnog kapitala. Ovaj model je prilično fleksibilan, tako da pruža mogućnost naknadnog dodavanja poduzeća koja se bave proizvodnjom različitih kultura.

description: We study the implications on both background and perturbation evolution of introducing a Chaplygin gas component in the universe's ingredients. We perform likelihood analyses using wide-ranging, SN1a, CMB and large scale structure observations to assess whether such a component could be a genuine alternative to a cosmological constant. We find that current data favors an adiabatic Chaplygin gas with behavior akin to a cosmological constant.

description: Since the early 1970s there has been interest in the application of optimal control theory to the management of economic systems. Specifically, optimal control theory prescribes policy strategies which optimise a quantifiable policy preference function subject to market equilibrium conditions. Problems of this kind have been identified among agricultural markets and this paper aims to illustrate the application of optimal control theory to the British potato market. The paper takes evidence from policy makers to derive target values for the producer price, imports, and the changes in the quota area from year to year. The constraints on optimisation are specified in terms of a partial equilibrium econometric model which specifies, demand, supply and trade relationships. The policy preference function is specified as a quadratic and a 'revealed preference approach' is employed to estimate the parameters which penalise market equilibria which over or under-shoot policy targets. The resulting optimal control problem is minimised by a dynamic programming routine. The results suggest that policy makers may benefit from taking dynamic effects directly into account when formulating policy strategies.

description: This presentation examines pathways for advancing renewable energy and decarbonization in Brazil, analyzing three scenarios: Business as Usual, expanded Distributed Generation Photovoltaic (DGPV) adoption, and increased electric vehicle (EV) use. Key findings highlight the importance of financial incentives for DGPV expansion, with a 35% cost reduction in solar technology expected to impact by 2042 significantly. A projected 20% increase in EVs by 2050 would contribute to a 20% emissions reduction with minimal strain on the electricity system. The report recommends long-term policy planning, integrated renewable energy and transportation policies, and further research on EV adoption and implementation challenges.

description: Few methods for controlling and treating Pierce’s Disease (PD) have been available, with efforts historically focused on controlling the sharpshooter vector (e.g., insecticides) or roguing seriously ill vines, both of which have demonstrated only limited success. However, an option that reduces PD in grapevines is now available, XylPhi-PD.™
 XylPhi-PD is a novel biological treatment for PD that is approved for use in organic production. This break-through technology was developed exclusively for viticulture. XylPhi-PD contains a cocktail of viral bacteriophages (bacteria-killing viruses) that enter and destroy X. fastidiosa bacteria.
 XylPhi-PD can be flexibly applied as a preventative to protect growing vines under disease pressure, or as a curative after disease symptoms become visible.
 Multiple field studies assessed the efficacy of XylPhi-PD for the treatment or prevention of Pierce’s Disease (PD) in vineyards, when used in accordance with label Directions for Use. In a 2015 Texas A&M study with natural infection exposure, 3 monthly XylPhi-PD treatments significantly reduced PD incidence 44% vs controls.
 In an ongoing 4-site study (up to 2 years of treatment in leading North Coast California commercial vineyards with high PD pressure), XylPhi-PD treatment of diverse wine varietals prompted reductions in visual PD symptoms of 60%, which was confirmed by qPCR.
 XylPhi-PD has consistently demonstrated significant efficacy across differing conditions and locales.
 These favorable outcomes distinguish XylPhi-PD as a targeted and effective strategy for protecting valuable vineyards against PD.

description: We identify the different contributions to quantum interference in a mesoscopic metallic loop in contact with two superconducting electrodes. At low temperature, a flux-modulated Josephson coupling is observed with strong damping over the thermal length L_{T}. At higher temperature, the magnetoresistance exhibits large h/2e-periodic oscillations with 1/T power law decay. This flux-sensitive contribution arises from coherence of low-energy quasiparticles states over the phase-breaking length L_ϕ. Mesoscopic fluctuations contribute as a small h/e oscillation, resolved only in the purely normal state.

description: Most of the time, electronic excitations in mesoscopic conductors are well described, around equilibrium, by non-interacting Landau quasi-particles. This allows a good understanding of the transport properties in the linear regime. However, the role of interaction in the non-equilibrium properties beyond this regime has still to be established. A paradigmatic example is the Kondo many body state, which can be realized in a carbon nanotube (CNT) quantum dot for temperatures below the Kondo temperature $T_K$. As CNT possess spin and orbital quantum numbers, it is possible to investigate the twofold degenerate SU(2) Kondo effect as well as the four fold degenerate SU(4) state by tuning the degeneracies and filling factor. This article aims at providing a comprehensive review on our recent works on the Kondo correlations probed by quantum noise measurement both at low and high frequencies and demonstrate how current noise measurements yield new insight on interaction effects and dynamics of a Kondo correlated state.

description: Macedonia has been a candidate-country for EU membership since 2005. The EU integrative process, without doubt, will have an impact on the Macedonian economy and particularly on the agricultural sector. So far, the farmers’ attitude and intentions with regard to the EU integration and accession have not been thoroughly investigated. Respectively, the objective of the paper is to provide understanding of the Macedonian farmers’ attitude and behavioural intentions in the context of EU accession and the potential policy and market changes. Furthermore, another issue is to establish whether there are significant discrepancies among farmers and their attitude towards EU accession. The results revealed that the farmer community in the country is quite heterogeneous in terms of farm and farmers’ profiles and farm management practices. The cluster analysis suggests that there are four clusters according to which the variables explaining the attitudes were significantly different, provisionally labelled as “optimist “, “moderate”, “restrained” and “sceptic”......Makedonija je država kandidat za ulazak u EU od 2005. Integracijski proces će nedvojbeno imati utjecaj na makedonsku ekonomiju, posebice na područuju poljoprivrede. Do sada nisu vršena značajnija istraživanja u vezi stavova i namjera poljoprivrednika u odnosu na integracije i pristup EU. U tom smislu, svrha ovoga rada jest pružiti uvid u stavove makedonskih poljoprivrednika i njihovih reakcija u kontekstu pristupa EU te potencijalne politike i promjena na tržištu. Nadalje, predmet istraživanja bilo je i utvrđivanje postoje li razlike između poljoprivrednika i njihovih stavova prema pristupanju EU. Rezultati su pokazali da su poljoprivrednici u zemlji poprilično heterogeni u smislu farme, profila poljoprivrednika i prakse vođenja farmi. Klaster analizom utvrđene su četiri grupe čije varijable reprezentiraju značajno različite stavove, provizorno označene kao „optimistični“, „umjereni“, „suzdržani“ i „skeptični“.
Electron correlations in a partially filled first excited Landau level

description: The form of electron correlations in a partially filled degenerate Landau level (LL) is related to the behavior of the anharmonic part of the interaction pseudopotential. Unlike in the lowest LL, the pseudopotential in the first excited LL is harmonic at short range. As a result, the incompressible states in this LL have different correlations, occur at different filling factors nu, and cannot be described by a composite fermion model. The series of Laughlin-correlated states of electron pairs is proposed at nu=2+2/(q_2+2) with integer q_2. It includes Moore-Read nu=5/2 state and the nu=7/3 state. Despite coincidence of the values of nu, the latter state has different correlations than Laughlin state of single electrons at nu=1/3 and, in finite systems, occurs at a different LL degeneracy (flux).
