description: Recently it has been conjectured that the ground-state of a Markovian Hamiltonian, with one boundary operator, acting in a link pattern space is related to vertically and horizontally symmetric alternating-sign matrices (equivalently fully-packed loop configurations (FPL) on a grid with special boundaries).We extend this conjecture by introducing an arbitrary boundary parameter. We show that the parameter dependent ground state is related to refined vertically symmetric alternating-sign matrices i.e. with prescribed configurations (respectively, prescribed FPL configurations) in the next to central row. We also conjecture a relation between the ground-state of a Markovian Hamiltonian with two boundary operators and arbitrary coefficients and some doubly refined (dependence on two parameters) FPL configurations. Our conjectures might be useful in the study of ground-states of the O(1) and XXZ models, as well as the stationary states of Raise and Peel models.

description: The quantum vacuum in a many-body system of finite nuclei has been investigated within the relativistic Hartree approach which describes the bound states of nucleons and anti-nucleons consistently. The contributions of the Dirac sea to the source terms of the meson-field equations are taken into account up to the one-nucleon loop and one-meson loop. The tensor couplings for the $ω$- and $ρ$-meson are included in the model. The overall nucleon spectra of shell-model states are in agreement with the data. The calculated anti-nucleon spectra in the vacuum differ about 20 -- 30 MeV with and without the tensor-coupling effects.

description: Automating sleep staging is vital to scale up sleep assessment and diagnosis to serve millions experiencing sleep deprivation and disorders and enable longitudinal sleep monitoring in home environments. Learning from raw polysomnography signals and their derived time-frequency image representations has been prevalent. However, learning from multi-view inputs (e.g., both the raw signals and the time-frequency images) for sleep staging is difficult and not well understood. This work proposes a sequence-to-sequence sleep staging model, XSleepNet, that is capable of learning a joint representation from both raw signals and time-frequency images. Since different views may generalize or overfit at different rates, the proposed network is trained such that the learning pace on each view is adapted based on their generalization/overfitting behavior. In simple terms, the learning on a particular view is speeded up when it is generalizing well and slowed down when it is overfitting. View-specific generalization/overfitting measures are computed on-the-fly during the training course and used to derive weights to blend the gradients from different views. As a result, the network is able to retain the representation power of different views in the joint features which represent the underlying distribution better than those learned by each individual view alone. Furthermore, the XSleepNet architecture is principally designed to gain robustness to the amount of training data and to increase the complementarity between the input views. Experimental results on five databases of different sizes show that XSleepNet consistently outperforms the single-view baselines and the multi-view baseline with a simple fusion strategy. Finally, XSleepNet also outperforms prior sleep staging methods and improves previous state-of-the-art results on the experimental databases.

description: One of base building stones of eGovernment development in the Czech Republic is so called Data boxes which were introduced to unify communication and to increase efficiency in public administration. The aim of a study carried out by the Department of Information Technologies was to analyze the implementation procedure and to use data boxes. The questioning took place in December 2009, i.e. c.6 weeks after introduction of duty to use a data box. Obtained results are important above all because the development process of eGovernment still does not end. The suggestion from data box implementation can significantly facilitate introduction of basic registers and other applications.

description: We present distance modulus and reddening determinations for 72 Galactic globular clusters from the homogeneous photometric database of Piotto et al. (2002), calibrated to the HST flight F439W and F555W bands. The distances have been determined by comparison with theoretical absolute magnitudes of the ZAHB. For low and intermediate metallicity clusters, we have estimated the apparent Zero Age Horizontal Branch (ZAHB) magnitude from the RR Lyrae level. For metal rich clusters, the ZAHB magnitude was obtained from the fainter envelope of the red HB. Reddenings have been estimated by comparison of the HST colour-magnitude diagrams (CMD) with ground CMDs of low reddening template clusters. The homogeneity of both the photometric data and the adopted methodological approach allowed us to obtain highly accurate relative cluster distances and reddenings. Our results are also compared with recent compilations in the literature.

description: Ni-Mn-In magnetic shape-memory Heusler alloys exhibit generally a large thermal hysteresis at their first-order martensitic phase transition which hinder a technological application in magnetic refrigeration. By optimizing the Cu content in Ni$_2$Cu$_x$Mn$_{1.4-x}$In$_{0.6}$, we obtained a thermal hysteresis of the martensitic phase transition in Ni$_{2}$Cu$_{0.2}$Mn$_{1.2}$In$_{0.6}$ of only 6 K. We can explain this very small hysteresis by an almost perfect habit plane at the interface of martensite and austenite phases. Application of hydrostatic pressure does not reduce the hysteresis further, but shifts the martensitic transition close to room temperature. The isothermal entropy change does not depend on warming or cooling protocols and is pressure independent. Experiments in pulsed-magnetic fields on Ni$_{2}$Cu$_{0.2}$Mn$_{1.2}$In$_{0.6}$ find a reversible magnetocaloric effect with a maximum adiabatic temperature change of -13 K.

description: Motivated by the unknown nature of the $2.50-2.67\,M_\odot$ compact object in the binary merger event GW190814, we study the maximum neutron star mass based on constraints from low-energy nuclear physics, neutron star tidal deformabilities from GW170817, and simultaneous mass-radius measurements of PSR J0030+045 from NICER. Our prior distribution is based on a combination of nuclear modeling valid in the vicinity of normal nuclear densities together with the assumption of a maximally stiff equation of state at high densities, a choice that enables us to probe the connection between observed heavy neutron stars and the transition density at which conventional nuclear physics models must break down. We demonstrate that a modification of the highly uncertain supra-saturation density equation of state beyond 2.64 times normal nuclear density is required in order for chiral effective field theory models to be consistent with current neutron star observations and the existence of $2.6\,M_\odot$ neutron stars. We also show that the existence of very massive neutron stars strongly impacts the radii of $\sim 2.0\,M_\odot$ neutron stars (but not necessarily the radii of $1.4\,M_\odot$ neutron stars), which further motivates future NICER radius measurements of PSR J1614-2230 and PSR J0740+6620.

Special attention has been paid, when graded submodules satisfies the gr-primeful property, to find extra properties of these graded submodules.

description: We use a versatile model to evaluate the multipartite entanglement and the nonclassical light generation in optical parametric oscillators, exploring the differences between doubly and triply resonant cavity configurations. We demonstrate the entanglement of the pump mode with converted fields in both situations, and the fundamental differences of oscillators using parametric down conversion and four wave mixing processes as the intracavity amplification technique. The strong correlations involving the sidebands of the pump and converted fields gives the signatures of a rich dynamic of multipartite entanglement.

description: The transition of East German agriculture led to major structural adjustments that showed some very particular phenomena. For instance, most of the successors of the former agricultural production cooperatives (LPGs) make slight losses and they operate at a higher employment level than new and re-established farms. In this paper we try to explain these phenomena with the farms' history prior to the transition period. Particular attention is given to sunk costs, the identity of members and employees, and old debts. A Data Envelopment Analysis of 210 financial statements distributed over the financial years 1992/93 to 1995/96 gives evidence that these historical arguments had a decisive impact on the farms' behaviour. However, this impact decreases over time, particularly because of a gradual replacement of assets.

description: Thomas-Fermi model is considered here to make it cogent to capture the Planck-scale effect with the use of a generalization of uncertainty relation. Here generalization contains both linear and quadratic terms of momentum. We first reformulate the Thomas-Fermi model for the non-relativistic case. It has been shown that it can also be reformulated for taking into account the relativistic effect. Dialectic screening for the non-relativistic cases has been studied and the expression of screening length has been found out explicitly.

description: An abundance analysis is presented and discussed for a sample of 14 RV Tauri stars. The present abundance data and those from our previous papers and by other workers are combined in an attempt to further understanding of the dust-gas separation process which afflicts many RV Tauri variables. We propose that a star's intrinsic (i.e., initial) metallicity is given by the photospheric zinc abundance. Variables warmer that about 5000 K and with an initial metallicity [Fe/H] $\geq$ $-$1 are affected by dust-gas separation. Variables of all metallicities and cooler than about $T_{\rm eff} \simeq 5000$ K are unaffected by dust-gas separation. The RV Tauri variables show a spread in their C abundances with the lower boundary of the points in the C versus Zn plane falling close to the predicted trend for giants after the first dredge-up. The upper boundary is inhabited by a few stars that are carbon-rich. The O abundances in the mean follow the predicted trend from unevolved stars in line with the expectation that photospheric O abundance is unaffected by the first dredge-up. An evolutionary scenario involving mass loss by a first ascent or early-AGB red giant, the primary star of a binary, is sketched.

description: Based upon the structure-conduct-performance approach the present paper analyses determinants of price-cost-margins over the business cycle for food industries in Germany, the USA as well as the Netherlands. Controlling for market structure variables, cyclical fluctuations in profitability are interpreted as evidence for changes in firm behaviour. The econometric panel data models reveal procyclic fluctuations of profits in highly concentrated industries in Germany. In contrast, profitability in competitive industries in Germany as well as in all US food industries are found to be more stable over the business cycle. This observation is explicable in terms of a more aggressive behaviour of firms in boom periods. The econometric model does not adequately explain industry differences in profitability in the Netherlands.

description: The present article discusses several pricing patterns and promotion activities in the German grocery retail industry. Special sales offers on the one hand and continuous pricing on the other hand affect the price instability of several selected products. Altogether the grocery retail industry exerts a stabilizing effect on prices in comparison with the price instability of agricultural commodities in the world market. Different price levels for products in some retail outlets show that a mixed price calculation is used. Price elasticities in the elastic part of the demand function for four selected products indicate that consumers react strongly to price discounts at the point of sale. Beside pricing strategies, different promotion activities affect demand for individual products strongly.

A Unified Dual-view Model for Review Summarization and Sentiment Classification with Inconsistency Loss
Creators: name: Chan, Hou Pong

Publisher: name: arXiv
Year: 2020
Subjects: subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: Acquiring accurate summarization and sentiment from user reviews is an essential component of modern e-commerce platforms. Review summarization aims at generating a concise summary that describes the key opinions and sentiment of a review, while sentiment classification aims to predict a sentiment label indicating the sentiment attitude of a review. To effectively leverage the shared sentiment information in both review summarization and sentiment classification tasks, we propose a novel dual-view model that jointly improves the performance of these two tasks. In our model, an encoder first learns a context representation for the review, then a summary decoder generates a review summary word by word. After that, a source-view sentiment classifier uses the encoded context representation to predict a sentiment label for the review, while a summary-view sentiment classifier uses the decoder hidden states to predict a sentiment label for the generated summary. During training, we introduce an inconsistency loss to penalize the disagreement between these two classifiers. It helps the decoder to generate a summary to have a consistent sentiment tendency with the review and also helps the two sentiment classifiers learn from each other. Experiment results on four real-world datasets from different domains demonstrate the effectiveness of our model.

description: The payments within the Rural Development Programme 2007- 2013 seek to improve the environment and contribute to rural development and economic growth. These policy measures may therefore have visual effects on the rural landscape. To achieve a measure of willingness to pay for these effects, a hedonic pricing approach is applied. The prices for staying at holdings in the “Staying on farms” registry are used to quantify the valuation of these visual effects. The results of this study indicate that there is a relationship between the price of rental objects and spatial variables constructed in GIS. Riparian strips and animals at the farm are positively valued. Cultivated land, grazing and meadow lands close to the settings are negatively valued. Hence, this study indicate that there is a positive willingness to pay for payments addressing user values in a diversified landscape and a negative willingness to pay for actions leading to a more monotonous landscape, such as payments to extensive grazing systems.

description: Computer science class enrollments have rapidly risen in the past decade. With current class sizes, standard approaches to grading and providing personalized feedback are no longer possible and new techniques become both feasible and necessary. In this paper, we present the third version of Automata Tutor, a tool for helping teachers and students in large courses on automata and formal languages. The second version of Automata Tutor supported automatic grading and feedback for finite-automata constructions and has already been used by thousands of users in dozens of countries. This new version of Automata Tutor supports automated grading and feedback generation for a greatly extended variety of new problems, including problems that ask students to create regular expressions, context-free grammars, pushdown automata and Turing machines corresponding to a given description, and problems about converting between equivalent models - e.g., from regular expressions to nondeterministic finite automata. Moreover, for several problems, this new version also enables teachers and students to automatically generate new problem instances. We also present the results of a survey run on a class of 950 students, which shows very positive results about the usability and usefulness of the tool.

Multi-criteria timber allocation models for the analysis of sustainable forest management decisions
Creators: name: Marinescu, Marian V.
Publisher: name: University of British Columbia
Year: 2009

description: The problem addressed in this dissertation is that of optimally allocating timber to different processing facilities, while meeting the multi-criteria conditions of sustainable forest management and integrating the medium-term and operational decisions. A Multi-criteria Timber Allocation Model using goal programming was developed to include various criteria and indicators for sustainable forest management. The allocation procedure was demonstrated using five allocation criteria: profit, employment, wildlife, recreation, and visual. In a case analysis, two multi-criteria allocation scenarios, generated with different sets of goal weights, were compared against a profit-based scenario. The results demonstrated the capability of the Multi-criteria Timber Allocation Model to deal with sustainability criteria in a practical and flexible manner. A DEA Timber Allocation Model was developed using Data Envelopment Analysis, a method of calculating technical efficiencies of different operations. The model was demonstrated using two allocation criteria: profit and employment. The allocation results were compared to those of random, profit-based, and employment-based allocations and suggested that the model balanced the two allocation criteria without the need for their prioritization. However, adding other allocation criteria was complicated by procedural concerns. A two-level Hierarchical Timber Allocation Model was developed to integrate the medium-term and operational decisions, while accounting for the sustainability criteria. At the medium-term level, the Multi-criteria Timber Allocation Model was implemented to optimally allocate stewardship units to different forest products companies. At the operational level, the FTP Analyzer®, a sawmilling optimization model, was implemented for each company to optimally process the allocated timber. An iterative algorithm was developed and demonstrated, in which the two planning levels reached mutually beneficial solutions. The model was demonstrated with an array of policy questions and revealed potential effects on both manufacturing processes and sustainability criteria. Future research was recommended to allow other criteria and indicators for sustainable forest management to be included in the DEA Timber Allocation Model. The Hierarchical Timber Allocation Model could also benefit from the addition of a strategic planning level, which could address the long-term, forest ecosystem management decisions and provide the medium-term level with available harvesting areas.

description: Recent observations of SgrA* by the GRAVITY instrument have astrometrically tracked infrared flares (IR) at distances of $\sim 10$ gravitational radii ($r_g$). In this paper, we study a model for the flares based on 3D general relativistic magnetohydrodynamic (GRMHD) simulations of magnetically arrested accretion disks (MADs) which exhibit violent episodes of flux escape from the black hole magnetosphere. These events are attractive for flare modeling for several reasons: i) the magnetically dominant regions can resist being disrupted via magneto-rotational turbulence and shear, ii) the orientation of the magnetic field is predominantly vertical as suggested by the GRAVITY data, iii) magnetic reconnection associated with the flux eruptions could yield a self-consistent means of particle heating/acceleration during the flare events. In this analysis we track erupted flux bundles and provide distributions of sizes, energies and plasma parameter. In our simulations, the orbits tend to circularize at a range of radii from $\sim 5-40 r_g$. The magnetic energy contained within the flux bundles ranges up to $\sim10^{40}$ erg, enough to power IR and X-ray flares. We find that the motion within the magnetically supported flow is substantially sub-Keplerian, in tension with the inferred period-radius relation of the three GRAVITY flares.

description: We present a general idea to construct methods for multi-qubit quantum teleportation between two remote parties with control of many agents in the network. Our methods seem to be much simpler than the existing method proposed recently (Phys. Rev. A {\bf 70}, 022329(2004)). We then demonstrate our idea by using several different protocols of quantum key distribution, including Ekert 91 and the deterministic secure communication protocol raised by Deng and Long.

description: Traditional objects of farm management research and farm management science are farms and farm households. In the course of time new objects have been added, for example different forms of horizontal and vertical co-operation, commerce and manufacturing enterprises in the field of agriculture, partly supplying, and service industries in agriculture. Corresponding to that, there are numerous addressees: relevant academics, students, farmers and their consultants, agricultural experts, also increasingly employees in agribusiness, agricultural societies and administrations, partly also jurisdiction, agrarian politicians, and finally the public. There is a large variety of topics concerning farm management research and science. Important traditional topics with varying focuses are: description of forms of enterprises, operations research and analysis, cooperate planning, appraisal, site assessment, use of electronic media, analysis of new technologies and their results, and finally the individual farm analysis of agrarian policy measures. Recent topics are in particular: economic research on organic farming, farm economic questions in connection with biotechnology and genetic engineering, farm economic controlling, internal procuring and marketing policy, business relations, analysis of international competitiveness of farm businesses as well as enterprises in agribusiness, farm environmental economy, and economic examinations of agricultural institutions. As far as organisation is concerned, farm management economics should stay in future within agricultural faculties. Farm management economics should not be classified as part of business economics and should not be integrated in business science faculties. Due to the large field of topics, farm management economics should have two professorships per faculty. Besides, a basic level of science has to be passed at any agricultural university. Above that, varied priority programs on special fields should be offered as it is currently the case.
An empirical investigation of the demand for bananas in Germany

description: We use econometric methods to investigate consumer demand for bananas and for other fruit in Germany. Monthly household survey data for the period 1986-1998 are analysed. Demand for bananas is significantly responsive to own price, suggesting that policy-induced price increases generate the usual dead-weight losses. Demand is also responsive to income changes, indicating that there is scope for further market expansion as incomes grow. There is evidence that other categories of fruit are both gross and net substitutes for bananas.

description: It is increasingly questionable whether the WTO regime is the most appropriate form of governance for addressing global problems related to agriculture. In particular, climate change, sustainability, hunger/poverty in developing countries, and expected imbalance in food demand-supply by 2050 are emerging as grave challenges to humanity and the WTO is still struggling to resolve issues (related to the multifunctional roles of agriculture) of the 20th century while completely lacking the capacity to tackle such new global issues of the 21st century. Given this outmoded institution, the primary objective of this article is to propose that a new system of governance is needed so as to exclusively and effectively deal with problems arising from the interactions among climate change, agricultural sustainability, food security, and trade.
Shape Function Effects in B -> X_c l ν_l

description: Owing to the fact that m_c^2 ~ m_b Λ_QCD, the endpoint region of the charged lepton energy spectrum in the inclusive decay B -> X_c l ν_l is affected by the Fermi motion of the initial-state b quark bound in the B meson. This effect is described in QCD by shape functions. Including the mass of the final-state quark, we find that a different set of operators as employed in Ref. hep-ph/0205150 is needed for a consistent matching, when incorporating the subleading contributions in B -> X_q l ν_l for both q = u and q = c. In addition, we modify the usual twist expansion in such a way that it yields a description of the lepton energy spectrum which is not just valid in the endpoint region, but over the entire phase space.

description: Methane is one of the simplest stable molecules that is both abundant and widely distributed across space. It is thought to have partial origin from interstellar molecular clouds, which are near the beginning of the star formation cycle. Observational surveys of CH$_4$ ice towards low- and high-mass young stellar objects showed that much of the CH$_4$ is expected to be formed by the hydrogenation of C on dust grains, and that CH$_4$ ice is strongly correlated with solid H$_2$O. Yet, this has not been investigated under controlled laboratory conditions, as carbon-atom chemistry of interstellar ice analogues has not been experimentally realized. In this study, we successfully demonstrate with a C-atom beam implemented in an ultrahigh vacuum apparatus the formation of CH$_4$ ice in two separate co-deposition experiments: C + H on a 10 K surface to mimic CH$_4$ formation right before H$_2$O ice is formed on the dust grain, and C + H + H$_2$O on a 10 K surface to mimic CH$_4$ formed simultaneously with H$_2$O ice. We confirm that CH$_4$ can be formed by the reaction of atomic C and H, and that the CH$_4$ formation rate is 2 times greater when CH$_4$ is formed within a H$_2$O-rich ice. This is in agreement with the observational finding that interstellar CH$_4$ and H$_2$O form together in the polar ice phase, i.e., when C- and H-atoms simultaneously accrete with O-atoms on dust grains. For the first time, the conditions that lead to interstellar CH$_4$ (and CD$_4$) ice formation are reported, and can be incorporated into astrochemical models to further constrain CH$_4$ chemistry in the interstellar medium and in other regions where CH$_4$ is inherited.

description: We discuss and model an experiment to study quasi-condensate growth on an atom chip. In particular, we consider the addition of a deep dimple to the weak harmonic trap confining an ultracold one-dimensional atomic Bose gas, below or close to the characteristic temperature for quasi-condensate formation. The subsequent dynamics depends critically on both the initial conditions, and the form of the perturbing potential. In general, the dynamics features a combination of shock-wave propagation in the quasi-condensate, and quasi-condensate growth from the surrounding thermal cloud.
