description: A Nyugat-dunántúli Régióval szomszédos Burgenlandban nagy hagyománya és számos, eredményes módja található a helyben előállított élelmiszerek értékesítésének. A szomszédos Ausztria jó néhány, több szempontból is példaértékű kezdeményezéssel büszkélkedhet a helyi termékek értékesítésében, az eredmények kulcsa legtöbb esetben a termelői szerveződésben, szövetkezésben lelhető fel. A regionális értékek, helyi termékek ismertsége meglehetősen kedvezőtlen képet mutat a Nyugat-dunántúli Régióban, és néhány pozitív példától eltekintve az értékesítés is a kezdetleges közvetlen termelői értékesítés szintjén mozog. A Nyugat-Pannon EU Régió (Burgenland tartományt és a Nyugat-dunántúli Régiót foglalja magában) adta lehetőségek kiaknázása, a tapasztalatcsere, együttműködés a közös turizmusfejlesztés, helyi termékadatbázis, termékmarketing és értékesítés fejlesztése terén még várat magára. ---------------------------------------- Burgenland, a region neighbour to the Western Transdanubian Region, has long-standing traditions and various successful methods for the marketing of local products. Austria boasts quite a few exemplary initiatives in the field of marketing local products. In most cases, success lies in the association and organisation of producers. Awareness of regional values and local products is rather low in the Western Transdanubian Region. With the exception of some positive examples, marketing is limited to rudimentary forms of direct selling by producers. The potential offered by the Western Pannonian EU Region (comprising the province of Burgenland and the Western Transdanubian Region) in terms of exchange of experience, cooperation in joint tourism projects, local product data base development, product marketing and sales promotion remains unused for the time being.

It is shown that these algorithms can be used in particular for checking the success of correction of the spectra by the methods of Vartiainen et al [1] and Lucarini et al [2] to remove the negative misplacement error in the terahertz time-domain spectroscopy.

description: We probe the stau-neutralino co-annihilation domain of the parameter space allowed by the current experimental bounds on the light Higgs mass, the b-> s γdecay, and the amount of neutralino cold dark matter within the framework of minimal SUGRA models at a 500 GeV e+e- linear collider. The most favorable signals of SUSY are stau pair production and neutralino pair production where the small mass difference between the lighter stau and the lightest neutralino in the co-annihilation region is ~5-15 GeV and hence generates low-energy tau leptons in the final state. This small mass difference would be a striking signal of many SUGRA models. We find that a calorimeter covering down to 1^o from the beams is crucial to reduce the two-photon background and the mass difference could be measured at a level of 10% with 500 fb^-1 of data where an invariant mass of two-tau jets and missing energy is used as a discriminator.

description: The collective excitations in the Bose-Hubbard model in a trap are studied by means of numerical diagonalization in one dimension. The strength function is calculated for monopole and dipole perturbations, and moments of the strength function are utilized in order to obtain information about the collective behavior under external forces. In the superfluid regime, the spectrum is found to be exhausted by one single frequency, while in systems that contain a Mott insulating plateau several frequencies are excited. An explanation of recent experimental findings in terms of a Mott plateau is suggested.

description: We report studies of semileptonic decays, B --> X_c l nu, based on a sample of 88 million BB events recorded with the BABAR detector. We have measured four moments of the electron energy distribution and four moments of the hadronic mass distribution, each as a function of the minimum electron energy. From these moments we determine the inclusive branching fraction, the CKM matrix element |V_cb|, and other heavy quark parameters, using Heavy Quark Expansions (HQE) to order 1/m_b^3 in the kinetic mass scheme. In addition, we have studied a large sample of exclusive B^0 --> D^*- l^+ nu decays. This sample is used to extract the vector and axial form factors, the normalization and slope of the HQET form factor to determine |V_cb|.

A méréseknél jelentős eltéréseket kaptunk, a legnagyobbakat az Inger és a Gudrun között. • A termelési mutatók közti értékbeli különbség (hajtásszám, vesszővastagság és -magasság) a fent említett energiafüzeknél a biomassza mennyiségében is megmutatkozott. The following findings were obtained concerning the energy willow hybrids tested: • Taking of cuttings is significantly affected by the timing of planting, the vitality and quality of cuttings, presence of various pests and pathogens, as well as ambient climatic conditions. • Growth dynamics is highly balanced with respect to individual hybrids, while there is a statistically detectable difference in growth intensity between different hybrids. • Shoot thickness is an indicator of quality and quantity for each hybrid. Measurement results varied greatly, the greatest differences were measured for Inger and Gudrun. • Variance in production indicators (number of shoots, shoot thickness and height) was also perceivable in biomass output of the energy willows.

description: Introduction: Situational judgement tests (SJTs) are widely used in selecting medical students and doctors. Emerging evidence suggests SJTs are capable of testing an individual’s ability to respond to role-relevant professionalism scenarios, however, evidence is lacking for their use in identifying students with concerning professional behaviours. This study aimed to determine the association between medical student professionalism-based SJT scores and recorded professionalism concerns during training. Methods: A cross-sectional study was conducted utilising SJT scores from second-year medical students and occurrences of student professionalism concerns. Concerns were reviewed and mapped to General Medical Council standards. Multivariate logistic regression was used to determine associations between SJT scores and professionalism concerns. Results: 247 students were included in the study. For every point increase in SJT score, students were 10% less likely to have multiple professionalism concerns [OR (95% CI) 0.90 (0.83–0.97); p = .007]. Students scoring below 1 and 2 standard deviations from the mean score were 4 and 11-times more likely to have multiple concerns [OR (95% CI) 4.52 (1.12–18.25); p = .034] and [OR (95% CI) 11.45 (1.72–76.15); p = .012]. Conclusion: Lower SJT scores were significantly associated with an increased risk of professionalism concerns. These findings support the potential for SJT exams to identify medical students that may require closer supervision and remediation during undergraduate education.

description: The ladder theory, in which the Bethe-Goldstone equation for the effective potential between two scattering particles plays a central role, is well known for its satisfactory description of the short-range correlations in the homogeneous electron liquid. By solving exactly the Bethe-Goldstone equation in the limit of large transfer momentum between two scattering particles, we obtain accurate results for the on-top pair-correlation density $g(0)$, in both three dimensions and two dimensions. Furthermore, we prove, in general, the ladder theory satisfies the cusp condition for the pair-correlation density $g(r)$ at zero distance $r=0$.

subject: vehicle routing problem
subject: heuristics (approximation method)

description: While transporting some material a circular way of the transportation is usually applied. Usually due to some capacity or time constraints or other reasons it is necessary to use more routes (i.e. more vehicles, or one vehicle must go out from its home place more times). This case is called the vehicle routing problem and there exist many types of this task because of the variety of reasons causing the necessity of use more than one route. Practically all the vehicle routing problems belong among the so-called NP-complete or NP-hard problems. This means that there exists no effective method which would succeed in finding a precise theoretical optimum for them. In such tasks, we can employ different approximation methods which provide us with solutions similar to a theoretical optimum and acceptable as an economic optimum. In practice, however, companies seldom pay enough attention to dealing with such problems, especially if transportation is not their principal work load and if it concerns a transportation task of a medium size. This article presents a case study of NOPEK Bakery in Vysoké Mýto. It demonstrates the effectiveness of the approximation method during the planning of the bakery products delivery to its customers. By the optimization of one of the so-called “fast deliveries“, we succeeded in the reduction of the number of vehicles needed for the delivery – about 18% – which turned out necessary. Similar savings of all “fast deliveries” in the company may lead to the reduction of tenure price (tenure fixture) by 17 mil. CZK. At the same time the profit will increase by 0.6 mil. CZK and profitability will go up by 2.5%. We also managed to ensure a balanced use of the vehicles. This made it possible for the bakery to deliver the goods to its customers in deadlines that they found more convenient.
Decoherence of Rabi oscillations in a single quantum dot

description: We develop a realistic model of Rabi oscillations in a quantum-dot photodiode. Based in a multi-exciton density matrix formulation we show that for short pulses the two-level models fails and higher levels should be taken into account. This affects some of the experimental conclusions, such as the inferred efficiency of the state rotation (population inversion) and the deduced value of the dipole interaction. We also show that the damping observed cannot be explained using \emph{constant} rates with fixed pulse duration. We demonstrate that the damping observed is in fact induced by an off-resonant excitation to or from the continuum of wetting layer states. Our model describes the nonlinear decoherence behavior observed in recent experiments.

Nonlocal magnon entanglement generation in coupled hybrid cavity systems

Subjects: subject: Quantum Physics (quant-ph)

description: We investigate dynamical generation of macroscopic nonlocal entanglements between two remote massive magnon-superconducting-circuit hybrid systems. Two fiber-coupled microwave cavities are employed to serve as an interaction channel connecting two sets of macroscopic hybrid units each containing a magnon (hosted by a Yttrium-Iron-Garnet sphere) and a superconducting-circuit qubit. Surprisingly, it is found that stronger coupling does not necessarily mean faster entanglement generation. The proposed hybrid system allows the existence of an optimal fiber coupling strength that requests the shortest amount of time to generate a systematic maximal entanglement. Our theoretical results are shown to be within the scope of specific parameters that can be achieved with current technology. The noise effects on the implementation of systems are also treated in a general environment suggesting the robustness of entanglement generation. Our discrete-variable qubit-like entanglement theory of magnons may lead to direct applications in various quantum information tasks.

description: Support vector machines (SVMs) are widely used for solving classification and regression problems. Recently, various nonparallel hyperplanes classification algorithms (NHCAs) have been proposed, which are comparable in terms of classification accuracy when compared with SVM but are computationally more efficient. All these NHCAs are originally proposed for binary classification problems. Since, most of the real world classification problems deal with multiple classes, these algorithms are extended in multi-category scenario. In this paper, we present a comparative study of four NHCAs i.e. Twin SVM (TWSVM), Generalized eigenvalue proximal SVM (GEPSVM), Regularized GEPSVM (RegGEPSVM) and Improved GEPSVM (IGEPSVM)for multi-category classification. The multi-category classification algorithms for NHCA classifiers are implemented using OneAgainst-All (OAA), binary tree-based (BT) and ternary decision structure (TDS) approaches and the experiments are performed on benchmark UCI datasets. The experimental results show that TDS-TWSVM outperforms other methods in terms of classification accuracy and BT-RegGEPSVM takes the minimum time for building the classifier

description: The coexistence of different viral strains (quasispecies) within the same host are nowadays observed for a growing number of viruses, most notably HIV, Marburg and Ebola, but the conditions for the formation and survival of new strains have not yet been understood. We present a model of HIV quasispecies competition, that describes the conditions of viral quasispecies coexistence under different immune system conditions. Our model incorporates both T and B cells responses, and we show that the role of B cells is important and additive to that of T cells. Simulations of coinfection (simultaneous infection) and superinfection (delayed secondary infection) scenarios in the early stages (days) and in the late stages of the infection (years) are in agreement with emerging molecular biology findings. The immune response induces a competition among similar phenotypes, leading to differentiation (quasi-speciation), escape dynamics and complex oscillations of viral strain abundance. We found that the quasispecies dynamics after superinfection or coinfection has time scales of several months and becomes even slower when the immune system response is weak. Our model represents a general framework to study the speed and distribution of HIV quasispecies during disease progression, vaccination and therapy.

description: In Mediterranean aquaculture little research has examined the interaction between rearing density and dietary composition on main key performance indicators, physiological processes and gut bacterial community. A study was undertaken, therefore to assess growth response, digestive enzyme activity, humoral immunity on skin mucus, plasma biochemistry and gut microbiota of gilthead sea bream (Sparus aurata, L. 1758) reared at high (HD) and low (LD) final stocking densities and fed high (FM30FO15, 30 % fishmeal FM, 15 % fish oil, FO) and low (FM10FO3; 10 % FM and 3 % FO) FM and FO levels. Isonitrogenous and isolipidic extruded diets were fed to triplicate fish groups (initial weight: 96.2 g) to overfeeding over 98 days. The densities tested had no major effects on overall growth and feed efficiency of sea bream reared at high or low FM and FO dietary level. Results of digestive enzyme activity indicated a comparable digestive efficiency among rearing densities and within each dietary treatment. Plasma parameters related to nutritional and physiological conditions were not affected by rearing densities under both nutritional conditions a similar observation was also achieved through the study of lysozyme, protease, antiprotease and total protein determination in skin mucus, For the first time on this species, the effect of rearing density on gut bacterial community was studied. Different response in relation to dietary treatment under HD and LD were detected. Low FM-FO diet maintained steady the biodiversity of the gut bacterial community between LD and HD conditions while fish fed high FM-FO level showed a reduced biodiversity at HD. According to the results, it seems feasible to rear gilthead sea bream at the on-growing phase at a density up to 36-44 kg m3 with low or high FM-FO diet without negatively affecting growth, feed efficiency, welfare condition and gut bacterial community.

description: Training deep neural networks usually requires a large amount of labeled data to obtain good performance. However, in medical image analysis, obtaining high-quality labels for the data is laborious and expensive, as accurately annotating medical images demands expertise knowledge of the clinicians. In this paper, we present a novel relation-driven semi-supervised framework for medical image classification. It is a consistency-based method which exploits the unlabeled data by encouraging the prediction consistency of given input under perturbations, and leverages a self-ensembling model to produce high-quality consistency targets for the unlabeled data. Considering that human diagnosis often refers to previous analogous cases to make reliable decisions, we introduce a novel sample relation consistency (SRC) paradigm to effectively exploit unlabeled data by modeling the relationship information among different samples. Superior to existing consistency-based methods which simply enforce consistency of individual predictions, our framework explicitly enforces the consistency of semantic relation among different samples under perturbations, encouraging the model to explore extra semantic information from unlabeled data. We have conducted extensive experiments to evaluate our method on two public benchmark medical image classification datasets, i.e.,skin lesion diagnosis with ISIC 2018 challenge and thorax disease classification with ChestX-ray14. Our method outperforms many state-of-the-art semi-supervised learning methods on both single-label and multi-label image classification scenarios.

Cost-performance trade-offs in haptic hardware design
Creators: name: Brouwer, Iman

description: The objective of this research was to determine whether low performance haptic hardware leads to the same surgical task performance compared to more expensive hardware in a virtual reality surgical simulator for laparoscopy. VR surgical simulators are currently being introduced in leading teaching hospitals around the world. While they provide great potential for improvement over current laparoscopic skills training methods, a major barrier to large-scale acceptance is their high cost. Therefore this study is performed to determine whether a reduction in quality and therefore cost can be obtained without affecting surgical task performance. To perform user test at different levels of haptic quality, we developed software that can introduce friction, cogging, force saturation, inertia, and backlash into the haptic loop, simulating the characteristics of less expensive hardware on a high-end haptic interface. This software avoids the need for an expensive hardware redesign, while it allows varying the different parameters on a continuous scale, independent from each other, and within a realistic range. In a pilot study expert surgeons performed a clip application (2 participants) and a dissection task (3 participants) on commercial haptic hardware and VR laparoscopic software. Each surgeon performed the task(s) 3 times under 5 different settings while forces and kinematic data were recorded. Two settings were picked from the ones mentioned above; the other three consisted of the unaltered high fidelity setting, zero force feedback, and a combination of force saturation, cogging, friction, and inertia. We compared tissue-interaction forces, velocities, tool-tip path lengths, and completion times between the high fidelity setting and each of the other 7 settings. At a significance level of 0.05 a Friedman test showed that only the no force feedback condition was significantly different from the high fidelity condition in applied 95 percentile forces. In the clip application task both 50 percentile, and 95 percentile forces were significantly different in the no force feedback condition compared to high fidelity. None of the other settings showed significant differences in any of the performance measures. These preliminary results suggest that low performance components can be used in haptic hardware for laparoscopy without affecting task performance, potentially creating a significant cost reduction.

description: The goal of this paper is to analyse the households’ environmental impact in a regional economy, including the household direct impact as well as the impact associated with the production of goods and services of the household demand. Moreover, per capita ecological impacts for each household category according to income level are obtained. We focus on water consumption, and water and atmospheric pollution. The framework is based on a regional SAMEA (Social Accounting Matrix and Environmental Accounts), and vertically integrated environmental indicators using the Leontief model. An application is carried out for the Aragon case.

description: We present ultraviolet photometry for a sample of morphologically early-type galaxies selected by matching the Sloan Digital Sky Survey Data Release 1 with the GALEX Medium and All-sky Imaging Surveys. We obtain a working sample of 1032 early-type galaxies with GALEX FUV detections, SDSS spectroscopy, and $z<0.2$. Using the SDSS spectra to identify galaxies with even weak star formation or evidence of AGN, and further removing galaxies with any evidence of non early-type morphology, we derive a final sample of 172 red quiescent early-type galaxies. We find that the $FUV-r$ color has a full range of 5 mag. Plotting against the $FUV-r$ color the metallicity sensitive Lick $\rm Mg_2$ and D4000 indices, and the stellar velocity dispersion, we find no correlation between our measurement of UV rising flux, and any parameter sensitive to metallicity.

description: In this paper we carry out a research of the CH4 emissions related to the Catalan agro-food sector through an alternative or at least complementary, input-output subsystems analysis, which is a useful tool to study the productive structure of the different sectors that make up an economy. The application of this technique allows the decomposition of the subsystem in different effects depending on the existing interindustry linkages with all the production sectors of the economy inside as well outside the subsystem. Results highlights the relevance of intrasectorial relations within the agro-food industry subsystem, which shows a significant autonomy respect to this type of emissions with regard to the rest of the economy. This feature guides the sort of environmental policies to be implemented in order to reduce the atmospheric impact of such activity

description: Fake news can have a significant negative impact on society because of the growing use of mobile devices and the worldwide increase in Internet access. It is therefore essential to develop a simple mathematical model to understand the online dissemination of fake news. In this study, we propose a point process model of the spread of fake news on Twitter. The proposed model describes the spread of a fake news item as a two-stage process: initially, fake news spreads as a piece of ordinary news; then, when most users start recognizing the falsity of the news item, that itself spreads as another news story. We validate this model using two datasets of fake news items spread on Twitter. We show that the proposed model is superior to the current state-of-the-art methods in accurately predicting the evolution of the spread of a fake news item. Moreover, a text analysis suggests that our model appropriately infers the correction time, i.e., the moment when Twitter users start realizing the falsity of the news item. The proposed model contributes to understanding the dynamics of the spread of fake news on social media. Its ability to extract a compact representation of the spreading pattern could be useful in the detection and mitigation of fake news.

description: The geometric thickness of a graph G is the minimum integer k such that there is a straight line drawing of G with its edge set partitioned into k plane subgraphs. Eppstein [Separating thickness from geometric thickness. In: Towards a Theory of Geometric Graphs, vol. 342 of Contemp. Math., AMS, 2004] asked whether every graph of bounded maximum degree has bounded geometric thickness. We answer this question in the negative, by proving that there exists Delta-regular graphs with arbitrarily large geometric thickness. In particular, for all Delta >= 9 and for all large n, there exists a Delta-regular graph with geometric thickness at least c Delta^{1/2} n^{1/2 - 4/Delta - epsilon}. Analogous results concerning graph drawings with few edge slopes are also presented, thus solving open problems by Dujmovic' et al. [Really straight graph drawings.

description: Vertical markets for foods are linked through pricing systems with much of the performance seen through how well price information is reflected at points of exchange. Price linkage models are estimated using recursive asymmetric methods for measuring price linkages in the U.S. food distribution system for 100 food commodities from January 1995 to June 2009. Preliminary results show that price linkages to be strong but declining over time with evidence of asymmetric in the long run. Long run rising prices are pass through more than falling.

description: We present Lick Natural Guide Star Adaptive Optics observations of the L8 brown dwarf Gliese 337C, which is resolved for the first time into two closely separated (0"53+/-0"03), nearly equal magnitude components with a K_s flux ratio of 0.93+/-0.10. Companionship is inferred from the absence of a 3"6 offset source in 2MASS or photographic plate images, implying that the observed secondary component is a co-moving late-type dwarf. With a projected separation of 11 AU and nearly equal-magnitude components, Gliese 337CD has properties similar to other known companion and field substellar binaries. Its long orbital period (estimated to be ~140-180 yr) inhibits short-term astrometric mass measurements, but the Gliese 337CD system is ideal for studying the L/T transition at a fixed age and metallicity. From a compilation of all known widely separated (>~100 AU) stellar/brown dwarf multiple systems, we find evidence that the binary fraction of brown dwarfs in these systems is notably higher than that of field brown dwarfs, 45(+15)(-13)% versus 18(+7)(-4)% for analogous samples. We speculate on possible reasons for this difference, including the possibility that dynamic (ejection) interactions which may form such wide pairs preferentially retain binary secondaries due to their greater combined mass and/or ability to absorb angular momentum.

description: A self-pulsing effect termed quantum echoes has been observed in experiments with an open superconducting and a normal conducting microwave billiard whose geometry provides soft chaos, i.e. a mixed phase space portrait with a large stable island. For such systems a periodic response to an incoming pulse has been predicted. Its period has been associated to the degree of development of a horseshoe describing the topology of the classical dynamics. The experiments confirm this picture and reveal the topological information.
