description: We present results from a multi-wavelength campaign to monitor the 2005 outburst of the low-mass young star V1118 Ori. Although our campaign covers the X-ray, optical, infrared, and radio regimes, we focus in this Letter on the properties of the X-ray emission in V1118 Ori during the first few months after the optical outburst. Chandra and XMM-Newton detected V1118 Ori at three epochs in early 2005. The X-ray flux and luminosity stayed similar within a factor of two, and at the same level as in a pre-outburst observation in 2002. The hydrogen column density showed no evidence for variation from its modest pre-outburst value of $N_\mathrm{H} \sim 3 \times 10^{21}$ cm$^{-2}$. However, a spectral change occurred from a dominant hot plasma ($\sim 25$ MK) in 2002 and in January 2005 to a cooler plasma ($\sim 8$ MK) in February 2005 and in March 2005. We hypothesize that the hot magnetic loops high in the corona were disrupted by the closing in of the accretion disk due to the increased accretion rate during the outburst, whereas the lower cooler loops were probably less affected and became the dominant coronal component.

description: We study how the exotic particles and supersymmetric partners would affect the discovery limit at the Tevatron and LHC for neutral gauge bosons in generic E_6 models. We examine the Z' decay in the extreme case that all of the particles are massless, then consider how the masses of non-standard model particles will affect the discovery limit. We also calculate the discovery limit for a supersymmetric E_6 model with a secluded sector as a concrete example of a model with a definite set of exotic particles. Its discovery limit is small compared with other E_6 models due to the U'(1) charge assignment.

description: This paper examines how farmers have adapted to the current range of climates across China. A cross sectional method is used to analyze irrigation choice and crop choice across 8,405 farmers in 28 provinces in China. We find that both irrigation and crop choice decisions are climate sensitive. Chinese farmers are more likely to irrigate when facing lower temperatures and less precipitation. Farmers in warmer places are more likely to choose oil crops, maize, and especially cotton and wheat, and are less likely to choose vegetables, potatoes, sugar and especially rice and soybeans. In wetter locations, farmers are more likely to choose soybeans, oil crops, sugar, vegetables, cotton and especially rice, and they are less likely to choose potato, wheat and especially maize. The analysis of how Chinese farmers have adapted to current climate, provides insight into how they will likely adapt when climate changes. The analysis does not take into account other background changes that may well occur, including changes in prices, technology, and water availability. Policy makers should anticipate that adaptation is important, that the magnitude of changes depends on the climate scenario, and that the desired changes depend on the location of each farm.

description: In this paper we specify and estimate producers’ risk preference using farm data. We allow heterogeneous risk preference across individuals and propose a specification to model the heterogeneity. We base farmers’ decision making on a utility maximization framework and incorporate both market and production risk in farmers’ decision making. We do not assume any specific utility function or distribution of risk. The empirical application to farm level production data shows that risk preference does vary among individuals; demographic and institutional factors have significant effect on producers’ risk attitude.

We consider compactly supported potentials depending holomorphically on a complex parameter $z$. For certain such families, for all $z$ except those in a pluripolar set, the associated resonance-counting function has order of growth $d$. Our proofs use some results from several complex variables.

description: In order to mitigate the food commodity price pressure on domestic markets in the 2007/08 marketing year, major exporting and importing countries, most of them developing economies, have adopted some trade policy changes such as imposing export bans (or raising restrictions) and reducing import tariffs. This paper evaluates the impact of those policies on the world price and trade of major agricultural commodities. We quantify the changes in prices, trade, production, and consumption by using a set of multi-country, multi-commodity, and partial-equilibrium models. Results show that most commodity prices increase when these trade policies are exercised. Rice price is distorted the most, followed by wheat and barley. The impact on the aggregate trade varies by commodities. Our analysis illustrates that the inefficient trade policies actually worsen the price inflation rather than solving the issue.

description: This study estimates the transfer efficiency of government payments on Canadian agriculture. Three measures of efficiency are used: (1) the capitalization of support into farmland values, (2) the rate of income stabilization, and (3) the effect of past government support on the variance of income. We derive transfer efficiency estimates by applying panel econometric techniques to provincial time series data. With regard to the capitalization formula, we find that the capitalization of government into farmland values is homogeneous across provinces. We estimate the rate of capitalization at approximately $11.76 for every $1.00 increase in government support. A substantial amount of heterogeneity was found for the stabilization equation. Four homogeneous regions were found for Canada: 1) Maritimes; 2) Central Canada; 3) Western Canada; and 4) British Columbia. Among these heterogeneous regions, substantial differences in the stabilization coefficient estimates were found. There is also evidence of a trend in government payments in the Maritimes, indicating evidence of rent seeking. The variance of income was found to be correlated with past levels of government support, indicating that government support may be causing a moral hazard problem.

description: The integer quantum Hall states at fillings $ν= 0$ and $|ν| = 1$ in monolayer graphene have drawn much attention as they are generated by electron-electron interactions. Here we explore aspects of the $ν= 0$ and $|ν| = 1$ quantum Hall states relevant for experimental samples. In particular, we study the effects of finite extent and finite temperature on the $ν= 0$ state and finite temperature for the $ν= 1$ state. For the $ν= 0$ state we consider the situation in which the bulk is a canted antiferromagnet and use parameters consistent with measurements of the bulk gap to study the edge states in tilted magnetic fields in order to compare with experiment [A. F. Young et al., Nature 505, 528 (2014)]. When spatial modulation of the order parameters is taken into account, we find that for graphene placed on boron nitride, the gap at the edge closes for magnetic fields comparable to those in experiment, giving rise to edge conduction with $G \sim 2e^2/h$ while the bulk gap remains almost unchanged. We also study the transition into the ordered state at finite temperature and field. We determine the scaling of critical temperatures as a function of magnetic field, $B$, and distance to the zero field critical point and find sublinear scaling with magnetic field for weak and intermediate strength interactions, and $\sqrt{B}$ scaling at the coupling associated with the zero field quantum critical point. We also predict that critical temperatures for $ν= 0$ states should be an order of magnitude higher than those for $|ν| = 1$ states, consistent with the fact that the low temperature gap for $ν= 0$ is roughly an order of magnitude larger than that for $|ν| = 1$.

description: We derive the Gardner storage capacity for associative networks of threshold linear units, and show that with Hebbian learning they can operate closer to such Gardner bound than binary networks, and even surpass it. This is largely achieved through a sparsification of the retrieved patterns, which we analyze for theoretical and empirical distributions of activity. As reaching the optimal capacity via non-local learning rules like backpropagation requires slow and neurally implausible training procedures, our results indicate that one-shot self-organized Hebbian learning can be just as efficient.

description: With the development of the biotechnology, more and more GM foods enter the food chain of the mankind. What are the consumers’ attitudes toward those foods? And what are their requirements for safety management derived from the emerging of those foods? By conducting a survey in Wuhan with a sample of 621 correspondents, the study collects the correspondents’ attitudes on GM foods and expectations on safety managements for those foods, and analyses impacts of consumers’ general preferences, specific perceptions on GM foods, and the special labeling usage behavior both on the attitudes formation in GM labeling and on the labeling choices using MNL models. The paper further proposes some suggestions in GM foods safety management based on the modeling results.
Are Neutron-Rich Elements Produced in the Collapse of Strange Dwarfs ?

description: The structure of strange dwarfs and that of hybrid stars with same baryonic number is compared. There is a critical mass (M~0.24M_sun) in the strange dwarf branch, below which configurations with the same baryonic number in the hybrid star branch are more stable. If a transition occurs between both branches, the collapse releases an energy of about of 3x10^{50} erg, mostly under the form of neutrinos resulting from the conversion of hadronic matter onto strange quark matter. Only a fraction (~4%) is required to expel the outer neutron-rich layers. These events may contribute significantly to the chemical yield of nuclides with A>80 in the Galaxy, if their frequency is of about one per 1500 years.

One-photon absorption by inorganic perovskite nanocrystals: A theoretical study

description: The one-photon absorption cross section of nanocrystals (NCs) of the inorganic perovskite CsPbBr$_{3}$ is studied theoretically using a multiband $\mathbf{k}\cdot\mathbf{p}$ envelope-function model combined with a treatment of intercarrier correlation by many-body perturbation theory. A confined exciton is described first within the Hartree-Fock (HF) approximation, and correlation between the electron and hole is then included in leading order by computing the first-order vertex correction to the electron-photon interaction. The vertex correction is found to give an enhancement of the near-threshold absorption cross section by a factor of up to 4 relative to the HF (mean-field) value of the cross section, for NCs with an edge length $L=9$-12 nm (regime of intermediate confinement). The vertex-correction enhancement factors are found to decrease with increasing exciton energy; the absorption cross section for photons of energy $ω=3.1$ eV (about 0.7 eV above threshold) is enhanced by a factor of only 1.4-1.5 relative to the HF value. The $\mathbf{k}\cdot\mathbf{p}$ corrections to the absorption cross section are also significant; they are found to increase the cross section at an energy $ω=3.1$ eV by about 30% relative to the value found in the effective-mass approximation. The theoretical absorption cross section at $ω=3.1$ eV, assuming a Kane parameter $E_{P}=20$ eV, is found to be intermediate among the set of measured values (which vary among themselves by nearly an order of magnitude) and to obey a power-law dependence $σ^{(1)}(ω)\propto L^{2.9}$ on the NC edge length $L$, in good agreement with experiment. The dominant contribution to the theoretical exponent 2.9 is shown to be the density of final-state excitons. The main theoretical uncertainty in these calculations is in the value of the Kane parameter $E_{P}$.

description: The paper discusses India’s agrarian crisis and the role of corporate-led contract farming in addressing these crisis. A two-stage Heckman model was used to explain determinants of participation in contract farming, and whether participation in contract farming affects farm income. The results indicate that contract farming has a positive impact on crop productivity and farm income. The socio-economic factors that influenced participation in contract farming were education, age, farm size, access to institutional credit, source of off-farm income and membership to an organization. Factors related to the likelihood of participation in contract farming slightly differed from the factors affecting farm income.

description: Historical star magnitudes from catalogues by Ptolemy (137 AD), as-Sufi (964) and Tycho Brahe (1602/27) are converted to the Johnson V-mag scale and compared to modern day values from the HIPPARCOS catalogue. The deviations (or "errors") are tested for dependencies on three different observational influences. The relation between historical and modern magnitudes is found to be linear in all three catalogues as it had previously been shown for the Almagest data by Hearnshaw (1999). A slight dependency on the colour index (B-V) is shown throughout the data sets and as-Sufi's as well as Brahe's data also give fainter values for stars of lower culmination height (indicating extinction). In all three catalogues, a star's estimated magnitude is influenced by the brightness of its immediate surroundings. After correction for the three effects, the remaining variance within the magnitude errors can be considered as approximate accuracy of the pre-telescopic magnitude estimates. The final converted and corrected magnitudes are available via the Vizier catalogue access tool (Ochsenbein, Bauer, & Marcout, 2000).

Given $n$ real numbers $a_{1},...,a_{n}$ with $\sum_{i=1}^{n}a_{i}^{2}=1$, then of the $2^{n}$ signed sums $\pm a_{1} \pm ... \pm a_{n}$, at least half have absolute value at most $1$. Hendriks and Van Zuijlen (2020) and Boppana (2020) independently proved that a proportion of at least $0.4276$ of these sums has absolute value at most $1$. Using different techniques, we improve this bound to $0.46$.

description: The aim of this article is to investigate the relationship between Economic Value Added, traditional performance measures (Return on Assets ‘ROA’ and Return on Equity ‘ROE’) and their ability to measure the creation of shareholder wealth in food-processing firms in the Czech Republic. To assess the relationship, a simple regression test was used and the following hypothesis were tested: • a strong positive linear relationship exists between EVA and the traditional performance measures of ROA and ROE and • the EVA measure reflects changes in shareholder wealth more consistently than the traditional performance measures ROA and ROE. The regression analysis results indicate in all cases a positive correspondence between EVA and financial performance metrics and show higher quality information content of EVA indicator as regards the ability to create shareholder wealth than the traditional performance measures.

description: We study the transport properties of directed percolation clusters at the upper critical dimension $d_{c} = 4+1$, where critical fluctuations induce logarithmic corrections to the leading (mean-field) scaling behavior. Employing field theory and renormalization group methods we calculate these logarithmic corrections up to and including the next to leading correction for a variety of observables, viz. the connectivity, i.e., the probability that two given points are connected, the average two-point resistance and some of the fractal masses describing percolation clusters. Furthermore, we study logarithmic corrections for the multifractal moments of the current distribution on directed percolation clusters.

description: The fast-growing US ethanol industry has historically been characterized by large downstream investments made by farmers. The authors assess the value which the stock market may hold for downstream investment by farmers as well as by ethanol manufacturers themselves. The model framework used herein expands on the original VEST framework developed by Siebert, Jones and Sporleder. A word of caution, the model herein is not intended to provide an on-going, risk-reducing business strategy. However, it can and does provide a quick method to calculate the reasonableness of a downstream investment request that a farmer (or any business person) might be challenged to consider. Although virtual stock market investments may certainly assist in value added performance, they (just like brick and mortar processing plants) can provide no guarantee of performance.

description: Using conjoint analysis methodology, this study used an online survey to measure consumers’ preferences for the apple attributes as place of production, method of production, and price. The results of the conjoint analysis indicate that consumers are willing to make trade offs between the studied attributes. Segment analysis indicates Place-oriented consumers may be willing to pay 60% to 70% premiums for locally grown apples. The high consumer preferences for locally grown products combined with environmental benefits transferred through genetic modification provide an opportunity for producers to capture and build their markets, especially within certain market segments.

To have a unitary and renormalizable theory, we propose a class of models with gauge symmetry $\prod_i G_i \times SU(3)'_C \times SU(2)'_L \times U(1)'_Y$ where the SM fermions and Higgs fields are singlets under the hidden gauge symmetry $\prod_i G_i$, and such massive vector bosons appear after the gauge symmetry is spontaneously broken down to the SM gauge symmetry. We discuss the model with SU(5) hidden gauge symmetry in detail, and comment on the generic phenomenological implications.

description: Learning on 3D scene-based point cloud has received extensive attention as its promising application in many fields, and well-annotated and multisource datasets can catalyze the development of those data-driven approaches. To facilitate the research of this area, we present a richly-annotated 3D point cloud dataset for multiple outdoor scene understanding tasks and also an effective learning framework for its hierarchical segmentation task. The dataset was generated via the photogrammetric processing on unmanned aerial vehicle (UAV) images of the National University of Singapore (NUS) campus, and has been point-wisely annotated with both hierarchical and instance-based labels. Based on it, we formulate a hierarchical learning problem for 3D point cloud segmentation and propose a measurement evaluating consistency across various hierarchies. To solve this problem, a two-stage method including multi-task (MT) learning and hierarchical ensemble (HE) with consistency consideration is proposed. Experimental results demonstrate the superiority of the proposed method and potential advantages of our hierarchical annotations. In addition, we benchmark results of semantic and instance segmentation, which is accessible online at https://3d.dataset.site with the dataset and all source codes.

description: Recent lattice QCD calculations show strong indications that the crossover of QCD at zero baryon chemical potential ($μ_B$) is a remnant of the second order chiral phase transition. The non-universal parameters needed to map temperature $T$ and $μ_B$ to the universal properties of the second order chiral phase transition were determined by lattice QCD calculations. Motivated by these advances, first, we discuss the analytic structure of the partition function -- the so-called Yang-Lee edge singularity -- in the QCD crossover regime, solely based on universal properties. Then, utilizing the lattice calculated non-universal parameters, we map this singularity to the real $T$ and complex $μ_B$ plane, in order to find the radius of convergence for a Taylor series expansion of QCD partition function around $μ_B=0$ in the QCD crossover regime. Our most important findings are: (i) An universality-based estimate of the radius of convergence around $μ_B=0$; (ii) Universality and lattice QCD based constraints on the location of the QCD critical point in the $T-μ_B$ plane.

description: The sensory and perceptual mechanisms of the human brain can be reconfigured so as to optimize the processing of a selected type or class of information (i.e. frequency, location, etc.). A foundational goal of cognitive neuroscience is to pursue an understanding of the neural processes that underlie this reconfiguration. Auditory selective attention has been the topic of considerable investigation, principally by the use of event-related potential (ERP) techniques to record certain electrophysiological correlates of attentional selection. The large majority of this work has focused on a single paradigm, known as the sustained-attention paradigm, in which listeners continuously focus their attention at a particular location or on a particular frequency of sound. Only a very few previous studies have investigated the more realistic situation in which listeners continuously reorient their attention on a moment-by-moment basis. This thesis reports the systematic investigation of transient auditory attention. The ERP technique was used to address questions regarding the neural correlates and functional anatomy of auditory selective attention in a variety of situations in which attention was continuously reoriented in space. Following a brief introduction and review in Chapter One, Chapter Two reports the result of the first high-density (64-electrode) study of the ERP correlates of transient spatial auditory attention. This chapter concludes with the speculation that transient attention modulates neurons within a dedicated spatial processing or "where" pathway that projects posteriorly and dorsally from auditory cortex. Chapter Three checks the assumptions of this hypothesis by identifying an ERP correlate of spatial processing and localizing the generator of this correlate to a region of cortex believed to constitute part of this "where" pathway. Finally, Chapter Four reports the results of several experiments that localized certain attention-related modulations of the ERP to this putative "where" pathway. These experiments also demonstrated that transient auditory attention involves a complex interaction between stimulus-driven and goal-driven (bottom-up and top-down) processes that lead to distinctly different patterns of ERP activity. The thesis concludes with a discussion of the advancements made, relative to the state of previous knowledge, as a result of the work presented here.

description: We introduce GACELA, a generative adversarial network (GAN) designed to restore missing musical audio data with a duration ranging between hundreds of milliseconds to a few seconds, i.e., to perform long-gap audio inpainting. While previous work either addressed shorter gaps or relied on exemplars by copying available information from other signal parts, GACELA addresses the inpainting of long gaps in two aspects. First, it considers various time scales of audio information by relying on five parallel discriminators with increasing resolution of receptive fields. Second, it is conditioned not only on the available information surrounding the gap, i.e., the context, but also on the latent variable of the conditional GAN. This addresses the inherent multi-modality of audio inpainting at such long gaps and provides the option of user-defined inpainting. GACELA was tested in listening tests on music signals of varying complexity and gap durations ranging from 375~ms to 1500~ms. While our subjects were often able to detect the inpaintings, the severity of the artifacts decreased from unacceptable to mildly disturbing. GACELA represents a framework capable to integrate future improvements such as processing of more auditory-related features or more explicit musical features.

Quantum entanglement and quantum nonlocality for $N$-photon entangled states

description: Quantum entanglement and quantum nonlocality of $N$-photon entangled states $|ψ_{N m}> =\mathcal{N}_{m}[\cosγ|N-m>_{1}|m>_{2} +e^{iθ_{m}}\sinγ|m>_{1}|N-m>_{2}]$ and their superpositions are studied. We indicate that the relative phase $θ_{m}$ affects quantum nonlocality but not quantum entanglement for the state $|ψ_{N m}>$. We show that quantum nonlocality can be controlled and manipulated by adjusting the state parameters of $|ψ_{N m}>$, superposition coefficients, and the azimuthal angles of the Bell operator. We also show that the violation of the Bell inequality can reach its maximal value under certain conditions. It is found that quantum superpositions based on $|ψ_{N m}>$ can increase the amount of entanglement, and give more ways to reach the maximal violation of the Bell inequality.

description: This case explores a cluster of firms that emerged sharing a particular ownership structure. Typically, clusters are thought of as interrelated firms that produce similar products and services. However, we document the emergence and evolution of a cluster of entrepreneurial ventures that developed using a unique governance structure. We explore the deviant case of Renville, MN because of its notable success in developing a series of entrepreneurial ventures that provided producers with the opportunity to vertically integrate.
Gibbs mixing of partially distinguishable photons with a polarising beamsplitter membrane

description: For a thought experiment concerning the mixing of two classical gases, Gibbs concluded that the work that can be extracted from mixing is determined by whether or not the gases can be distinguished by a semi-permeable membrane; that is, the mixing work is a discontinuous function of how similar the gases are. Here we describe an optomechanical setup that generalises Gibbs' thought experiment to partially distinguishable quantum gases. Specifically, we model the interaction between a polarising beamsplitter, that plays the role of a semi-permeable membrane, and two photon gases of non-orthogonal polarisation. We find that the work arising from the mixing of the gases is related to the potential energy associated with the displacement of the microscopic membrane, and we derive a general quantum mixing work expression, valid for any two photon gases with the same number distribution. The quantum mixing work is found to change continuously with the distinguishability of the two polarised gases. In addition, fluctuations of the work on the microscopic membrane become important, which we calculate for Fock and thermal states of the photon gases. Our findings generalise Gibbs' mixing to the quantum regime and open the door for new quantum thermodynamic (thought) experiments with quantum gases with non-orthogonal polarisations and microscopic pistons that can distinguish orthogonal polarisations.

Monte Carlo simulations of star clusters -- III. A million body star cluster
Creators: name: Giersz, Mirek
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A revision of Stodolkiewicz's Monte Carlo code is used to simulate the evolution of million body star clusters. The new method treats each superstar as a single star and follows the evolution and motion of all individual stellar objects. A survey of the evolution of N-body systems influenced by the tidal field of a parent galaxy and by stellar evolution is presented. The process of energy generation is realized by means of appropriately modified versions of Spitzer's and Mikkola's formulae for the interaction cross section between binaries and field stars and binaries themselves. The results presented are in good agreement with theoretical expectations and the results of other methods. During the evolution, the initial mass function (IMF) changes significantly. The local mass function (LMF) around the half--mass radius closely resembles the actual global mass function (GMF). At the late stages of evolution the mass of the evolved stars inside the core can be as high as 97% of the total mass in this region. For the whole system, the evolved stars can compose up to 67% of the total mass. The evolution of cluster anisotropy strongly depends on initial cluster concentration, IMF and the strength of the tidal field. The results presented are the first step in the direction of simulating the evolution of real globular clusters by means of the Monte Carlo method.
