description: Witnessing a rapid surge in irrigation requirements as well as the pressure on natural resources to augment production for satisfying grain demand for the growing human and livestock population, ground water supply in the Texas Panhandle reflects itself as a limiting yet indispensable factor. This study evaluates the effectiveness of eight potential water management strategies in terms of water savings, implementation costs as well as the regional impact of each policy on the agricultural economy of Region A, comprising 21 counties in the North Texas High Plains, over a fifty-year planning horizon.

description: Existing semantic segmentation models heavily rely on dense pixel-wise annotations. To reduce the annotation pressure, we focus on a challenging task named zero-shot semantic segmentation, which aims to segment unseen objects with zero annotations. This task can be accomplished by transferring knowledge across categories via semantic word embeddings. In this paper, we propose a novel context-aware feature generation method for zero-shot segmentation named CaGNet. In particular, with the observation that a pixel-wise feature highly depends on its contextual information, we insert a contextual module in a segmentation network to capture the pixel-wise contextual information, which guides the process of generating more diverse and context-aware features from semantic word embeddings. Our method achieves state-of-the-art results on three benchmark datasets for zero-shot segmentation. Codes are available at: https://github.com/bcmi/CaGNet-Zero-Shot-Semantic-Segmentation.

description: Knowledge of magnetic symmetry is vital for exploiting nontrivial surface states of magnetic topological materials. EuIn$_{2}$As$_{2}$ is an excellent example, as it is predicted to have collinear antiferromagnetic order where the magnetic moment direction determines either a topological-crystalline-insulator phase supporting axion electrodynamics or a higher-order-topological-insulator phase with chiral hinge states. Here, we use neutron diffraction, symmetry analysis, and density functional theory results to demonstrate that EuIn$_{2}$As$_{2}$ actually exhibits low-symmetry helical antiferromagnetic order which makes it a stoichiometric magnetic topological-crystalline axion insulator protected by the combination of a 180$^{\circ}$ rotation and time-reversal symmetries: $C_{2}\times\mathcal{T}=2^{\prime}$. Surfaces protected by $2^{\prime}$ are expected to have an exotic gapless Dirac cone which is unpinned to specific crystal momenta. All other surfaces have gapped Dirac cones and exhibit half-integer quantum anomalous Hall conductivity. We predict that the direction of a modest applied magnetic field of $H\approx1$ to $2$ T can tune between gapless and gapped surface states.

description: We derive the Veneziano-Yankielowicz superpotential directly from the matrix model by fixing the measure precisely. The essential requirement here is that the effective superpotential of the matrix model corresponding to the ${\cal N}=4$ supersymmetric Yang-Mills theory vanishes except for the tree gauge kinetic term. Thus we clarify the reason why the matrix model reproduces the Veneziano-Yankielowicz superpotential correctly in the Dijkgraaf-Vafa theory.

description: We study the mass spectrum of baryons with two and three charmed quarks. For double charm baryons the spin splitting is found to be smaller than standard quark-model potential predictions. This splitting is not influenced either by the particular form of the confining potential or by the regularization taken for the contact term of the spin-spin potential. We consistently predict the spectra for triply charmed baryons.

Long-Term Near-Infrared Brightening of Non-Variable OH/IR Stars

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Non-variable OH/IR stars are thought to have just left the asymptotic giant branch (AGB) phase. In this conventional picture, they must still show strong circumstellar extinction caused by the dust ejected during the AGB phase, and the extinction is expected to decrease over time because of the dispersal of the circumstellar dust after the cessation of the stellar mass loss. The reduction of the extinction makes the stars become apparently brighter and bluer with time especially in the near-infrared (NIR) range. We look for such long-term brightening of non-variable OH/IR stars by using 2MASS, UKIDSS, and OAOWFC survey data. As a result, we get multi-epoch NIR data taken over a 20-year period (1997-2017) for 6 of 16 non-variable OH/IR stars, and all six objects are found to be brightening. The K-band brightening rate of five objects ranges from 0.010 to 0.130 mag yr$^{-1}$, which is reasonably explained with the conventional picture. However, one OH/IR star, OH31.0-0.2, shows a rapid brightening, which cannot be explained only by the dispersal of the dust shell. Multi-color (J-, H-, and K-band) data are obtained for three objects, OH25.1-0.3, OH53.6-0.2, and OH77.9+0.2. Surprisingly, none of them appears to have become bluer, and OH53.6-0.2 is found to have been reddened with a rate of 0.013 mag yr$^{-1}$ in (J-K). Our findings suggest other mechanisms such as rapid changes in stellar properties (temperature or luminosity) or a generation of a new batch of dust grains.

On the quantum description of Einstein's Brownian motion

Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)

description: A fully quantum treatment of Einstein's Brownian motion is given, showing in particular the role played by the two original requirements of translational invariance and connection between dynamics of the Brownian particle and atomic nature of the medium. The former leads to a clearcut relationship with Holevo's result on translation-covariant quantum-dynamical semigroups, the latter to a formulation of the fluctuation-dissipation theorem in terms of the dynamic structure factor, a two-point correlation function introduced in seminal work by van Hove, directly related to density fluctuations in the medium and therefore to its atomistic, discrete nature. A microphysical expression for the generally temperature dependent friction coefficient is given in terms of the dynamic structure factor and of the interaction potential describing the single collisions. A comparison with the Caldeira Leggett model is drawn, especially in view of the requirement of translational invariance, further characterizing general structures of reduced dynamics arising in the presence of symmetry under translations.

description: This study compares liquidity costs and other characteristics of electronic and open outcry hard red winter wheat futures contracts traded on the Kansas City Board of Trade. Liquidity costs are considerably lower in the electronic market than in the open outcry market. A new approach is used to estimate liquidity costs which eliminates bias resulting from splitting of orders in electronic markets. The liquidity costs are still considerably lower after correcting the bias in electronic market. Liquidity costs were higher in after-hours trading as compared to regular trading hours suggesting a negative impact of volume on liquidity costs. Volatility of futures prices and volume per trade are positively related to liquidity costs, while a negative relation is found between daily volume and liquidity costs. Round-number pricing is more prevalent in the open outcry market. Daily volumes were found distinctively higher during the rolling period as a result of Goldman-Sachs Roll. Trade size is larger in the open outcry market.

Monitoring and information reporting for sustainable forest management in North America and Europe : requirements, practices and perceptions
Creators: name: Hickey, Gordon M.
Publisher: name: University of British Columbia
Year: 2009

description: Internationally, the institutions created to address forest management have ranged from hard laws, put in place by governments through legislation, to soft laws such as forest certification. Each of these approaches requires enforcement and evaluation through monitoring and information reporting. Monitoring is central to a jurisdiction's understanding of the resources that it manages and the values that it aims to protect. It is also an essential component of adaptive management. Monitoring and information reporting for sustainable forest management (SFM) in selected jurisdictions in North America and Europe were investigated through applied grounded theory, multiple case studies and survey analysis methods. The research considered the requirements documented in hard and soft law standards, the practices of third-party certified forestry companies and the perceptions of forestry-related stakeholders in the selected jurisdictions. The analysis of the monitoring and information reporting requirements documented in selected hard law standards indicated that despite differences in the level of detail, general similarities existed in different jurisdictions. The analysis of soft law standards demonstrated a high degree of variability in the specific requirements related to monitoring and information reporting. Significant differences were found to exist between the soft law standards from Europe, USA and Canada. The multiple case study analysis highlighted differences in the level of formal monitoring and information reporting being conducted at the smaller scales of forest management when compared to the larger forestry companies. It also revealed a high level of similarity in the nature of monitoring and information reporting practices both within and between different jurisdictions of North America and Europe. The results of the survey research highlighted the degree to which the perceptions of a sample of stakeholders can differ between Europe, USA and Canada. An obvious disparity was observed between the results from Canada and the rest of the sample, indicating a stronger perceived need for more data and information related to forest management in the Canadian context. The results have broad applicability beyond a local geographical or ecological situation as evidenced through the international focus of the study and the broad participation of industry from North America and Europe.
Detecting topological orders through continuous quantum phase transition

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We study a continuous quantum phase transition that breaks a $Z_2$ symmetry. We show that the transition is described by a new critical point which does not belong to the Ising universality class, despite the presence of well defined symmetry breaking order parameter. The new critical point arises since the transition not only break the $Z_2$ symmetry, it also changes the topological/quantum order in the two phases across the transition. We show that the new critical point can be identified in experiments by measuring critical exponents. So measuring critical exponents and identifying new critical points is a way to detect new topological phases and a way to measure topological/quantum orders in those phases.

We perform phase-space optimization of manifestly $CP$-odd observables ($\boldsymbol ω$), sensitive to the sign of $\tilde κ$, and constructed from experimentally accessible final state momenta. We identify a simple optimized linear combination $\boldsymbol α\cdot \boldsymbolω$ that gives similar sensitivity as the studied fully fledged ML models. Using $\boldsymbolα\cdot \boldsymbolω$ we project the expected sensitivities to $\tilde κ$ at HL-LHC, HE-LHC, and FCC-hh.

description: Three new structural factors underlie the latest great world crisis: (1) the incorporation of highly populated countries into the growth process; (2) The increasing scarcity of the environment and certain natural resources; (3) the dramatic concentration of wealth and income in the advanced economies over the last two decades. These structural changes have significantly tightened the links between world growth and commodity demand, made the world commodity supply increasingly inelastic, and rendered economic growth more dependent on lax monetary and financial policies, respectively. All this may make the world economy highly vulnerable to crises and may make the recovery from the current crisis more difficult.

Exact bounds for dynamical critical exponents of transverse-field Ising chains with a correlated disorder

description: This study investigates the dynamical critical exponent of disordered Ising chains under transverse fields to examine the effect of a correlated disorder on quantum phase transitions. The correlated disorder, where the on-site transverse field depends on the nearest-neighbor coupling strengths connecting the site, gives a qualitatively different result from the uncorrelated disorder. In the uncorrelated disorder cases where the transverse field is either homogeneous over sites or random independently of the nearest-neighbor coupling strengths, the dynamical critical exponent is infinite. In contrast, in the presence of the correlated disorder, we analytically show that the dynamical critical exponent is finite. We also show that the dynamical critical exponent depends on the tuning process of the transverse field strengths.

description: The authors present a review of the systematic studies of the structure of macroscopically planar thin films at the air-liquid interface (water, alkali solution and silica hydrosol). A common feature of the considered works is the application of a model-independent approach to the analysis of X-ray reflectometry data, which does not require a priori assumptions about the structure of the object under study. It is shown that the experimental results obtained with the laboratory source in some cases are qualitatively on par with the results of those obtained with the use of synchrotron radiation source. The reproducibility of the effect of spontaneous ordering in films of amphiphilic organic molecules (phospholipids) at the surface of the colloidal solution of silica nanoparticles is demonstrated. The possibility of influencing the kinetics of the in situ formation of a phospholipid film by enriching the liquid substrate with alkali metal ions is also discussed.

Improved Band Gaps and Structural Properties from Wannier-Fermi-Löwdin Self-Interaction Corrections for Periodic Systems

description: The accurate prediction of band gaps and structural properties in periodic systems continues to be one of the central goals of electronic structure theory. However, band gaps obtained from popular exchange-correlation functionals (such as LDA and PBE) are severely underestimated partly due to the spurious self-interaction error (SIE) inherent to these functionals. In this work, we present a new formulation and implementation of Wannier function-derived Fermi-Löwdin (WFL) orbitals for correcting the SIE in periodic systems. Since our approach utilizes a variational minimization of the self-interaction energy with respect to the Wannier charge centers, it is computationally more efficient than the HSE hybrid functional and other self-interaction corrections that require a large number of transformation matrix elements. Calculations on several (17 in total) prototypical molecular solids, semiconductors, and wide-bandgap materials show that our WFL self-interaction correction approach gives better band gaps and bulk moduli compared to semilocal functionals, largely due to the partial removal of self-interaction errors.

description: Quantum theory is awash in multidimensional integrals that contain exponentials in the integration variables, their inverses, and inverse polynomials of those variables. The present paper introduces a means to reduce pairs of such integrals to one dimension when the integrand contains powers times an arbitrary function of xy/(x+y) multiplying various combinations of exponentials. In some cases these exponentials arise directly from transition-amplitudes involving products of plane waves, hydrogenic wave functions, Yukawa and/or Coulomb potentials. In other cases these exponentials arise from Gaussian transforms of such functions.

description: Since 2000 a number of factors impacted agricultural markets drastically. Among these are structural changes in global demand and repeated supply constraints that supported the observed positive development of agricultural prices. Given the increasingly interdependent global markets, the question arises of in how far an isolated view of a single market, when analysing price volatility, is sufficient? The paper is a contribution to the debate on the recent commodity price bubble and the relationship among commodity futures markets for agricultural raw materials. More particularly, the transmission of price volatility between commodity future markets is analysed. The background question is whether and to what extent the volatility of agricultural commodity prices at different market places have been transferred during the drastic price changes of 2008. In this analysis the volatility of the maize future price at three different commodity futures exchange is modelled as a multivariate GARCH - process. By doing so, interactions between stock markets in different venues are incorporated. The results of the econometric analysis are discussed against the background of the developments in agricultural and biofuel policy.

description: Consumers’ growing concerns with regard to the food supply chain continue to influence their perceptions of emerging novel food processes. The main objective of this study was to explore consumers’ perceptions and potential purchase motivations for chilled ready meals produced using high pressure processing. In-depth one-to-one soft laddering interviews were conducted in-home with 40 purchasers of chilled ready meals, aged between 18 and 44 years, living in Dublin City and County, Ireland. The in-depth discussions explored a range of issues concerning consumers’ acceptance of high pressure processing, as well as their preferences for high pressure processed chilled ready meal concepts. The results of the study showed that consumers were generally receptive towards high pressure processing of chilled ready meals. Subsequent discussions revealed where consumer acceptance issues could potentially arise concerning the application of high pressure processing to chilled ready meals. The soft laddering technique revealed distinct differences between consumer groups across consumption patterns and life stages with regard to their purchase preferences and potential purchase motivations. The insights generated from this research can assist companies design consumer-relevant communication strategies, which effectively differentiate high pressure processed chilled ready meal from incumbent products.

description: This paper considers balanced truncation of discrete-time Hankel $k$-positive systems, characterized by Hankel matrices whose minors up to order $k$ are nonnegative. Our main result shows that if the truncated system has order $k$ or less, then it is Hankel totally positive ($\infty$-positive), meaning that it is a sum of first order lags. This result can be understood as a bridge between two known results: the property that the first-order truncation of a positive system is positive ($k=1$), and the property that balanced truncation preserves state-space symmetry. It provides a broad class of systems where balanced truncation is guaranteed to result in a minimal internally positive system.

description: Since 2005 the EU food industry has primary legal responsibility for food safety control. This requires new responsibilities and relationships between government and industry, and between companies. This research presents a framework for incentive systems for food safety control in supply chains. It emphasizes key elements of food safety control from multiple perspectives and provides insights for the design and analysis of incentive systems for food safety control. An incentive system combines inter-company incentive mechanisms with intra-company decision making processes to control a hazard within the legal environment. Incentive mechanisms, which consist of a performance measure and a performance reward, induce companies to use control measures. The framework can be used to analyze the effectiveness and efficiency of alternative incentive systems in which companies have to cooperate with partners from other stages of the supply chain.

description: This paper presents a political economy model of public standards in an open economy model. We use the model to derive the political optimum and to analyze different factors that have an influence on this political equilibrium. The paper discusses how the level of development influences the political equilibrium. We also analyze the relation between trade and the political equilibrium and compare this political outcome with the social optimum to identify under which cases ‘under-standardization’ or ‘over-standardization’ results, and which standards can be labeled as (producer)protectionist measures.
Mobile impurity in a Bose-Einstein condensate and the orthogonality catastrophe

description: We analyze the properties of an impurity in a dilute Bose-Einstein condensate (BEC). First the quasiparticle residue of a static impurity in an ideal BEC is shown to vanish with increasing particle number as a stretched exponential, leading to a bosonic orthogonality catastrophe. Then we introduce a variational ansatz, which recovers this exact result and describes the macroscopic dressing of the impurity including its back-action onto the BEC as well as boson-boson repulsion beyond the Bogoliubov approximation. This ansatz predicts that the orthogonality catastrophe also occurs for mobile impurities, whenever the BEC becomes ideal. Finally, we show that our ansatz agrees well with experimental results.
What are ‘true’ loyal consumers in the food sector? Insights from an empirical study

description: Because loyal consumers are less likely to switch to competitors and because they are more tolerant to increases in price than non-loyal consumers, one of the main aims of firms is the “generation” of loyal consumers. But what is consumer loyalty? The marketing literature emphasises that for “true loyalty” it is important to consider both consumers' purchasing pattern (i.e. repurchases) as well as the underlying attitudes of the consumers. Thus, true loyalty includes both a behavioural (purchase) component, which results in repeated purchases, and an attitudinal component, which results in a dispositional commitment to a product, a brand, or a company, and associates a unique value to it. However, considering the characteristics of food products and the sector the question arises whether the above mentioned strict definition of true consumer loyalty is realistic in the food sector. The aim of our paper is to empirically test this question. In order to test our research question we conduct 30 semi-structured in-death interviews with regular customers of an organic retail shop in March / April 2009. Each interview lasts for roughly thirty minutes.
Successful Producer Owned Marketing Organisations in a Transition Country: Two Case Studies from Hungarian Agribusiness

Subjects: subject: Agricultural and Food Policy

subject: trust
subject: management
subject: vertical co-ordination.

description: Starting point of our analysis is that independent privately owned farm organisations in transition countries like Hungary can not countervail the market power of their business partners; therefore closer coordination (integration) of agricultural producers seems an appropriate solution. Apart from some theoretical considerations on co-operative rationale (based on New Institutional Economics), the main aim of the paper is presenting 2 case studies on producer owned marketing organisations from Hungarian agribusiness, one from the fruit and vegetable sector and the other one from the dairy chain. Conclusions from case studies are the followings. Such producers’ organisations, like the Mórakert Co-operative and Alföldi Milk Selling and Supplying Ltd. can be a solution for farmers to cope with their problems arising from incomplete pricing mechanisms and to reduce transaction costs, at least at the regional level. They also are good examples for the vertical integration based on the horizontal coordination of farmers as initiators. Despite recent liquidity problems, they also proves that by cooperation there is an opportunity to significantly improve their countervailing power and to establish ownership for farmers in the upper part of the food chain if they can secure strict quality requirements, solid financing, loyalty and trust in their organisations.
Modeling "Equitable and Sustainable Well-being" (BES) using Bayesian Networks: A Case Study of the Italian regions

description: Measurement of well-being has been a highly debated topic since the end of the last century. While some specific aspects are still open issues, a multidimensional approach as well as the construction of shared and well-rooted systems of indicators are now accepted as the main route to measure this complex phenomenon. A meaningful effort, in this direction, is that of the Italian "Equitable and Sustainable Well-being" (BES) system of indicators, developed by the Italian National Institute of Statistics (ISTAT) and the National Council for Economics and Labour (CNEL). The BES framework comprises a number of atomic indicators measured yearly at the regional level and reflecting the different domains of well-being (e.g. Health, Education, Work \& Life Balance, Environment,...). In this work we aim at dealing with the multidimensionality of the BES system of indicators and try to answer three main research questions: I) What is the structure of the relationships among the BES atomic indicators; II) What is the structure of the relationships among the BES domains; III) To what extent the structure of the relationships reflects the current BES theoretical framework. We address these questions by implementing Bayesian Networks (BNs), a widely accepted class of multivariate statistical models, particularly suitable for handling reasoning with uncertainty. Implementation of a BN results in a set of nodes and a set of conditional independence statements that provide an effective tool to explore associations in a system of variables. In this work, we also suggest two strategies for encoding prior knowledge in the BN estimating algorithm so that the BES theoretical framework can be represented into the network.

description: A Humane Society video, made secretly at the Westland/Hallmark plant in late 2007 and released in early 2008, led to the recall of 143 million pounds of beef. This case study illustrates the complexity of the food industry and the food recall process. Although ultimately, the incident had more to do with animal welfare than food safety — no sicknesses were tied to the recalled beef, it resulted in changes to the nation’s food safety procedures. The 2008 Westland/Hallmark beef recall, the largest beef recall in U.S. history, is a stepping-off point to examine the beef supply chain generally and the ground beef supply chain specifically.

description: The chameleon mechanism is a way to give an effective mass to a light scalar field via field self-interaction and interaction with matter. We study this mechanism in models in which the couplings are field dependent and find that the properties are very different from the case of constant couplings. The consequence of a runaway potential for the radion field in brane world scenarios and whether the radion can play the role of dark energy is investigated. The cosmological evolution during the inflationary epoch, the radiation and the matter dominated epochs are discussed as is the compatibility of the radion field with local tests of gravity.

Review of new flow friction equations: Constructing Colebrook explicit correlations accurately

Year: 2020
Subjects: subject: Numerical Analysis (math.NA)

description: Using only a limited number of computationally expensive functions, we show a way how to construct accurate and computationally efficient approximations of the Colebrook equation for flow friction. The presented approximations are based on the asymptotic series expansion of the Wright Omega-function and symbolic regression. The results are verified with 8 million of Quasi-Monte Carlo points covering the domain of interest for engineers. In comparison with the built-in wrightOmega feature of Matlab R2016a, the herein introduced related approximations of the Wright Omega-function significantly accelerate the computation. With only two logarithms and several basic arithmetic operations used, the presented approximations are not only computationally efficient but also extremely accurate. The maximal relative error of the most promising approximation which is given in the form suitable for engineers use is limited to 0.0012%, while for a little bit more complex variant is limited to 0.000024%.
