description: The precise values of the running quark and lepton masses $m^{}_f(μ)$, which are defined in the modified minimal subtraction scheme ($\overline{\rm MS}$) with $μ$ being the renormalization scale and the subscript $f$ referring to all the charged fermions in the Standard Model (SM), are very useful for the model building of fermion masses and flavor mixing and for the precision calculations in the SM or its new-physics extensions. In this paper, we calculate the running fermion masses by taking account of the up-to-date experimental results collected by Particle Data Group and the latest theoretical higher-order calculations of relevant renormalization-group equations and matching conditions in the literature. The emphasis is placed on the quantitative estimation of current uncertainties on the running fermion masses, and the linear error propagation method is adopted to quantify the uncertainties, which has been justified by the Monte-Carlo simulations. We identify two main sources of uncertainties, i.e., one from the experimental inputs and the other from the truncations at finite-order loops. The correlations among the uncertainties of running parameters can be remarkable in some cases. The final results of running fermion masses at several representative energy scales are tabulated for further applications.

description: The organic market is a very particular one. Starting from the premise that organic products are confidence and credibility products which cannot be easily differentiated from the rest, we find that consumers face a risk when purchasing them. In Spain, the marketing chain does not follow the conventional stages in most of the cases, so there is always some uncertainty about how the products will be sold. In addition, the great majority of the Spanish organic production is marketed abroad. In this paper we show some of the results of an investigation project in this topic.

Последнее десятилетие отмечается значительное увеличение интереса к проблеме хирургического лечения пациентов старшей возрастной группы с приобретенными пороками сердца. Широкий спектр моделей искусственных биологических протезов позволяет хирургу правильно подобрать метод коррекции порока сердца. Таким образом, правильный подбор модели протеза и метода коррекции порока сердца позволит улучшить отдаленные результаты хирургических методик этой категории тяжелых больных.
description: The aim of the article is to review modern cardiac surgery approaches to treatment of degenerative aortic valve failures. In the past decade there has been a growing interest in the problem of surgical treatment of patients of the senior age group with valvular heart diseases. A wide range of artificial bioprosthetic heart valves allows a surgeon to select properly the method for correction of a heart defect. Therefore the correct selection of the prosthesis model and the method of correction for the heart defect will allow improving the long-term results of surgical techniques for this severe category of patients.

description: We here present a new version of the publicly available general relativistic magnetohydrodynamic (GRMHD) code $\texttt{Spritz}$, which now includes an approximate neutrino leakage scheme able to handle neutrino cooling and heating. The leakage scheme is based on the publicly available $\texttt{ZelmaniLeak}$ code, with a few modifications in order to properly work with $\texttt{Spritz}$. We discuss the involved equations, physical assumptions, and implemented numerical methods, along with a large battery of general relativistic tests performed with and without magnetic fields. Our tests demonstrate the correct implementation of the neutrino leakage scheme, paving the way for further improvements of our neutrino treatment and the first application to magnetized binary neutron star mergers. We also discuss the implementation in the $\texttt{Spritz}$ code of high-order methods for a more accurate evolution of hydrodynamical quantities.

description: In the Organic Agriculture Supply Chain (OASC), the creation of trust finds its formal application into a process and product certification guaranteed by independent inspectors of the Organic Agriculture Certification Bodies (OACB). This study is aimed at analysing the role of OACB in creating trust between the actors involved into the OASC in Italy. Information about sixteen Italian OACB structures, field activities and factors constituting trust within the OASC were collected, through web-site exploration and direct surveys. Results show that the Ministry and final customers are valued as the more important subjects to OACB reputation building. Moreover, creating trust for OACB relies more on internal performance.

description: Quantitative risk assessment models are playing a minor role in the development of the new EU legal framework for food safety. There is a tendency of the EU institutions to apply the precautionary principle versus the predisposition of the USA institutions to rely on risk analysis. This paper provides a comparison of the role played by quantitative risk assessment models in the development of new policies on food safety in the EU and in the USA, focusing on a study case: the supply chain of shell eggs. We suggest that EU regulatory bodies should reconsider the role that quantitative risk assessment models have to play in order to design more effective food safety management systems.

description: The role of trust in eight selected agri-food chains in four EU countries is explored. The empirical analysis is based on a qualitative assessment of 28 expert interviews conducted in summer/autumn 2005. The findings suggest that trust is more pronounced among SMEs which are characterised by the existence of personal relationships between business partners. However, as is clear for pork breeders, if a source of distrust exists, trust may not fully develop. Also, if the general economic situation is difficult, the development of trust may be hampered, because all chain participants are struggling to command a share of a diminishing margin within the chain. Finally, if economic power is distributed unevenly, as is the case in Germany, Ireland, Spain and the UK where retailers dominate most chains, trust towards the more powerful may be limited.

description: We present a determination of the gluon polarization Delta G/G in the nucleon, based on the helicity asymmetry of quasi-real photoproduction events, Q^2<1(GeV/c)^2, with a pair of large transverse-momentum hadrons in the final state. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarized muon beam scattered on a polarized 6-LiD target. The helicity asymmetry for the selected events is = 0.002 +- 0.019(stat.) +- 0.003(syst.). From this value, we obtain in a leading-order QCD analysis Delta G/G=0.024 +- 0.089(stat.) +- 0.057(syst.) at x_g = 0.095 and mu^2 =~ 3 (GeV}/c)^2.

description: With the recent advances in technology, automatic speech recognition (ASR) has been widely used in real-world applications. The efficiency of converting large amounts of speech into text accurately with limited resources has become more important than ever. This paper proposes a method to rapidly recognize a large speech database via a Transformer-based end-to-end model. Transformers have improved the state-of-the-art performance in many fields. However, they are not easy to use for long sequences. In this paper, various techniques to speed up the recognition of real-world speeches are proposed and tested, including decoding via multiple-utterance batched beam search, detecting end-of-speech based on a connectionist temporal classification (CTC), restricting the CTC prefix score, and splitting long speeches into short segments. Experiments are conducted with the Librispeech English and the real-world Korean ASR tasks to verify the proposed methods. From the experiments, the proposed system can convert 8 hours of speeches spoken at real-world meetings into text in less than 3 minutes with a 10.73% character error rate, which is 27.1% relatively lower than that of conventional systems.

description: The needs of the organic eggs are increasing; therefore, the farmers of chicken-egg (FCE) provide the best eggs to their consumers to satisfy their needs and wants. Because the FCE cannot satisfy every consumer' needs, FCE has to focus on some specific groups to satisfy their needs and wants. This paper is to clarify the segmentation of the customers in middle Taiwan and build the empirical model via Cluster Analysis. The 460 samples are taken randomly without some adjustment, but only 341 samples are used. As the results, this paper gets the segmentations of product oriented, economic oriented, and production oriented, and which would be the target markets that the FCE should focus on.

description: Natural human interactions for Mixed Reality Applications are overwhelmingly multimodal: humans communicate intent and instructions via a combination of visual, aural and gestural cues. However, supporting low-latency and accurate comprehension of such multimodal instructions (MMI), on resource-constrained wearable devices, remains an open challenge, especially as the state-of-the-art comprehension techniques for each individual modality increasingly utilize complex Deep Neural Network models. We demonstrate the possibility of overcoming the core limitation of latency--vs.--accuracy tradeoff by exploiting cross-modal dependencies -- i.e., by compensating for the inferior performance of one model with an increased accuracy of more complex model of a different modality. We present a sensor fusion architecture that performs MMI comprehension in a quasi-synchronous fashion, by fusing visual, speech and gestural input. The architecture is reconfigurable and supports dynamic modification of the complexity of the data processing pipeline for each individual modality in response to contextual changes. Using a representative "classroom" context and a set of four common interaction primitives, we then demonstrate how the choices between low and high complexity models for each individual modality are coupled. In particular, we show that (a) a judicious combination of low and high complexity models across modalities can offer a dramatic 3-fold decrease in comprehension latency together with an increase 10-15% in accuracy, and (b) the right collective choice of models is context dependent, with the performance of some model combinations being significantly more sensitive to changes in scene context or choice of interaction.

description: We examine the interaction of marketing channel members and the influence of these interactions on incentives, coordination costs, and risk allocation strategies in a food marketing channel. For this purpose we specify a three-stage principal-agent marketing channel model involving producers, wholesalers, retailers and a futures market. We compare the situation with and without futures market. The empirical results regarding the Dutch ware potato marketing channel during 1971-2003 reveals that, possibly as a result of increases in incentives to producers and wholesalers, the coordination costs of the marketing channel decreased significantly, both with and without futures trade. The coordination costs of a marketing channel with a futures market are lower than without futures, demonstrating the price discovery role of the futures markets. The results also show that risk shifted from retailers to producers and wholesalers.

Search for new physics in top quark production with additional leptons in proton-proton collisions at $\sqrt{s} =$ 13 TeV using effective field theory
Creators: name: CMS Collaboration

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: Events containing one or more top quarks produced with additional prompt leptons are used to search for new physics within the framework of an effective field theory (EFT). The data correspond to an integrated luminosity of 41.5 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV at the LHC, collected by the CMS experiment in 2017. The selected events are required to have either two leptons with the same charge or more than two leptons; jets, including identified bottom quark jets, are also required, and the selected events are divided into categories based on the multiplicities of these objects. Sixteen dimension-six operators that can affect processes involving top quarks produced with additional charged leptons are considered in this analysis. Constructed to target EFT effects directly, the analysis applies a novel approach in which the observed yields are parameterized in terms of the Wilson coefficients (WCs) of the EFT operators. A simultaneous fit of the 16 WCs to the data is performed and two standard deviation confidence intervals for the WCs are extracted; the standard model expectations for the WC values are within these intervals for all of the WCs probed.

Морфологические исследования тканей Фатерова сосочка проводились у 98 умерших, страдавших описторхозом, учитывались также данные прижизненного обследования. Для оценки силы влияния факторов использовались методы многофакторного корреляционно-регрессионного анализа. Получено, что толщина эпителиального слоя большого сосочка двенадцатиперстной кишки с 95 %-й вероятностью может являться ≪индикатором≫ изменений в сосочке при описторхозном папиллите, при этом 87 % (р = 0,000) возможных изменений толщины эпителиального слоя обусловлены влиянием факторов длительности и интенсивности инвазии, при этом сила влияния временного фактора в 3,8 раза больше влияния фактора интенсивности инвазии (р = 0,000).
description: The aim of the study is to evaluate possible morphofunctional connections and assess their effectiveness, in particular the duration and intensity of opisthorchiasis invasion on the pathomorphosis of tissues of the major duodenal papilla with opisthorchiasis papillitis. The morphological examinations of papilla tissues in 98 deceased are performed. Intravital analyses are taken into account. Methods of multifactor correlation-regression analysis are used to assess the influence of the factors. The following data is obtained: the thickness of the epithelial layer of the major duodenal papilla with a probability of 95 % could be an “indicator” of changes in the papilla with opisthorchiasis papillitis; moreover, 87 % (p = 0.000) of possible changes in the thickness of the epithelial layer are due to the influence from duration and intensity of invasion; furthermore, the influence of the time factor is 3.8 times greater than the influence of the invasion intensity factor (p = 0.000).

description: Neural networks have been used as variational wave functions for quantum many-particle problems. It has been shown that the correct sign structure is crucial to obtain the high accurate ground state energies. In this work, we propose a hybrid wave function combining the convolutional neural network (CNN) and projected entangled pair states (PEPS), in which the sign structures are determined by the PEPS, and the amplitudes of the wave functions are provided by CNN. We benchmark the ansatz on the highly frustrated spin-1/2 $J_1$-$J_2$ model. We show that the achieved ground energies are competitive to state-of-the-art results.

description: We present a research plan to assess the value of transparency by comparing pork supply chains in The Netherlands and China.We assume that chain performance depends on chain configuration, which depends on societal context and its associated quality control institutions. We define chain configuration in terms of structure and transparency. In order to be able to assess the influence of societal context and its quality control institutions on chain configuration and performance, we compare two countries that have very different societies. Ultimately, our goal is to be able to indicate whether a certain chain configuration suits all, or whether chain configuration should be tailored to societal context.

description: Dark sectors with purely gravitational couplings to the Standard Model are unavoidably populated from the SM plasma by graviton exchange, and naturally provide DM candidates. We examine the production in the relativistic regime where the dark sector is approximately scale invariant, providing general analytical formulas that depend solely on the central charge of the dark sector. We then assess the relevance of interactions that can lead to a variety of phenomena including thermalisation, nonperturbative mass gaps, out-of-equilibrium phase transitions and cannibalism in the dark sector. As an illustrative example we consider the dark glueball scenario in this light and show it to be a viable DM candidate due to the suppression of gravitational production. We go on to extend these results to strongly coupled CFTs and their holographic duals at large-N with the dark dilaton as the DM candidate.

description: The GLIMPSE (Galactic Legacy Mid-Plane Survey Extraordinaire) Point Source Catalog of ~ 30 million mid-infrared sources towards the inner Galaxy, 10 < |l| < 65 degrees and |b| < 1 degree, was used to determine the distribution of stars in Galactic longitude, latitude, and apparent magnitude. The counts versus longitude can be approximated by the modified Bessel function N=N_0*(l/l_0)*K_1(l/l_0), where l_0 is insensitive to limiting magnitude, band choice, and side of Galactic center: l_0= 17-30 degrees with a best fit value in the the 4.5 micron band of l_0=24 +/- 4 degrees. Modeling the source distribution as an exponential disk yields a radial scale length of H= 3.9 +/- 0.6 kpc. There is a pronounced north-south asymmetry in source counts for |l| < 30 degrees, with ~ 25% more stars in the north. For l=10-30 degrees, there is a strong enhancement of stars of m= 11.5-13.5 mag. A linear bar passing through the Galactic center with half-length R_bar=4.4 +/- 0.5 kpc, tilted by phi=44 +/- 10 degrees to the Sun-Galactic Center line, provides the simplest interpretation of this data. We examine the possibility that enhanced source counts at l=26-28 degrees, 31.5-34 degrees, and 306-309 degrees are related to Galactic spiral structure. Total source counts are depressed in regions where the counts of red objects (m_K-m_[8.0] >3) peak. In these areas, the counts are reduced by extinction due to molecular gas and/or high diffuse backgrounds associated with star formation.

Dynamics and control of orbiting deployable multimodule manipulators
Creators: name: Cao, Yang
Publisher: name: University of British Columbia
Year: 2009

description: This thesis focuses on the planar dynamics and control of a variable geometry manipulator which may be used in space- as well as ground-based operations. The system is composed of a flexible orbiting platform supporting two modules connected in a chain topology. Each module consists of two links: one free to slew while the other permitted to deploy. The model used and the governing order-N equations of motion, as developed by Caron, are explained. A detailed dynamical response study is undertaken which assesses the influence of initial conditions, system parameters, and manipulator maneuvers on the system response. Results suggest that under critical combinations of system parameters and disturbances the response may not conform to the acceptable limit. This points to a need for active control. Two different control methodologies are used: (i) the nonlinear Feedback Linearization Technique (FLT) applied to rigid degrees of freedom with flexible generalized coordinates indirectly regulated through coupling; (ii) a synthesis of the FLT and Linear Quadratic Regulator (LQR) to achieve active control of both rigid and flexible degrees of freedom. Furthermore, the FLT is used to track several prescribed trajectories with considerable accuracy. Finally, a two unit ground-based prototype manipulator, designed and constructed by Chu, is used to assess effectiveness of the Proportional-Integral- Derivative (PID) and FLT control procedures in performing several trajectory tracking maneuvers. The study lays a sound foundation for further exploration of this class of novel manipulators.

description: The dominant charge state for the Ga vacancy in GaAs has been the subject of a long debate, with experiments proposing $-$1, $-$2 or $-$3 as the best answer. We revisit this problem using {\it ab initio} calculations to compute the effects of temperature on the Gibbs free energy of formation, and we find that the thermal dependence of the Fermi level and of the ionization levels lead to a reversal of the preferred charge state as the temperature increases. Calculating the concentrations of gallium vacancies based on these results, we reproduce two conflicting experimental measurements, showing that these can be understood from a single set of coherent LDA results when thermal effects are included.

description: Until today no tool exists which allows adequate measurement of trust and its antecedents in food-networks. The application of existing tools is not really appropriate, since studies concerning the operationalisation of trust show that the antecedents influencing trustworthiness differ depending on the considered industry and the number of trust dimensions. Therefore the goal of this paper is to develop a new measurement tool (including operationalisation and antecedents) of trust in food networks based on the use of qualitative and quantitative empirical methods. First of all, the present literature on operationalisation of trust will be tested concerning what can be used in business networks. Further to this, existing studies will be surveyed to determine if the specification of the construct trust was formative or reflective and what would be the correct design of a study for business networks dealing with complex products. Finally, the results from the interviews with experts from food-networks about antecedents of trust are summarized to specify the measurement tool of trust.

description: Data scarcity, bias, and experimental noise are all frequently encountered problems in the application of deep learning to chemical and material science disciplines. Transfer learning has proven effective in compensating for the lack in data. The use of quantum calculations in machine learning enables the generation of a diverse dataset and ensures that learning is less affected by noise inherent to experimental databases. In this work, we propose a transfer learning approach for the prediction of solvation free energies that combines fundamentals from quantum calculations with the higher accuracy of experimental measurements. The employed model architecture is based on the directed-message passing neural network for the molecular embedding of solvent and solute molecules. A significant advantage of models pre-trained on quantum calculations is demonstrated for small experimental datasets and for out-of-sample predictions. The improved out-of-sample performance is shown for new solvents, for new solute elements, and for the extension to higher molar mass solutes. The overall performance of the pre-trained models is limited by the noise in the experimental test data, known as the aleatoric uncertainty. On a random test split, a mean absolute error of 0.21 kcal/mol is achieved. This is a significant improvement compared to the mean absolute error of the quantum calculations (0.40 kcal/mol). The error can be further reduced to 0.09 kcal/mol if the model performance is assessed on a more accurate subset of the experimental data.

description: DNA methylation (5-methylcytosine; 5mC) is central to early development, stem cell dynamics, and aging and has been implicated in the control of a wide range of diseases including cancer and neurodegenerative disorders. 5-methylcytosine can get converted to 5-hydroxymethylcytosine (5hmC) via the activity of Ten-eleven translocation methylcytosine dioxygenase enzymes (TET enzymes). Studies have shown that 5hmC is a stable mark and functionally distinct from 5mC. Furthermore, 5hmC plays important roles in a variety of biological processes, including neurological plasticity, immunology and other dynamic systems. Although it is imperative to distinguish both modifications, traditional epigenetic research tools have so far not been able to accurately decipher these marks, which had led to confounding analyses.

Epigenetix Ltd. (CEGX) has developed TrueMethyl® oxidative bisulfite-Seq (oxBS-Seq), a technology that allows accurate quantitation of 5mC and 5hmC at single base resolution. OxBS-Seq is compatible with conventional array and enrichment techniques such as the Infinium HumanMethylation450 Bead Chip array (450k), amplicon sequencing, pyrosequencing, as well as NGS-based methods, including targeted sequencing and whole genome analysis, making it a powerful tool for accurate DNA modification analyses across different epigenetic research areas.

description: The paper presents the results of the sociological survey and expertise describing the factors of risk reduction and increase of the level of trust in contract relations in food networks. The level of contract discipline is analyzed. It is shown that the insufficient rate of development of the institution of trust restricts the liberty of action for companies operating in a food network, deprives them of the opportunity to achieve the local optima and provides no grounds for setting their economic behavior sure-footed standards. Following the sociological survey the dynamics and structure of the transaction costs in food networks are displayed along with the specific features of their accounting in the company's operations. An expertise of the most important risk factors encountered at the current stage of development of the food networks is presented. Case studies for a number of companies enabled to reveal the advantages and contradictions of pursuing the strategies of diversification and integration as a means to reduce the external risks and uncertainties and overcome the negative impact of the asymmetric market information and underdeveloped institutional trust. A quantitative analysis of the synergetic effects from implementing the diversification strategy was made for a number of food companies to find out that the risks get reduced almost twice. At the same time, it is discovered that the transition of diversified companies from the zone of critical risks to that of minimum risks bears both positive and negative consequences. One the one hand, these are lower operational costs, more efficient distribution of the resources, greater market value of the company. But on the other hand, the above gains are offset by the excessively complicated organizational structure, dissipation of the resources, impediments to restructuring and etc.

description: The isotopic and isotonic distributions of the projectile fragmentation products have been simulated by a modified statistical abrasion-ablation (SAA) model and the isoscaling behavior of projectile-like fragments has been discussed. The isoscaling parameters $α$ and $β$ for hot fragments before evaporation and cold fragments after evaporation have been extracted, respectively. It looks that the evaporation has strong effect on $α$. For cold fragments, a monotonic increase of $α$ and $|β|$ with the increasing of $Z$ and $N$ is observed. The relation between isoscaling parameter and the change of isospin content is demonstrated. In addition, the disappearance of the isospin effect of projectile fragmentation is also discussed in the viewpoint of isoscaling parameter.

Random-Phase Approximation in Many-Body Noncovalent Systems: Methane in a Dodecahedral Water Cage

description: The many-body expansion (MBE) of energies of molecular clusters or solids offers a way to detect and analyze errors of theoretical methods that could go unnoticed if only the total energy of the system was considered. In this regard, the interaction between the methane molecule and its enclosing dodecahedral water cage, CH$_4$(H$_2$O)$_{20}$, is a stringent test for approximate methods, including density-functional theory (DFT) approximations. Hybrid and semilocal DFT approximations behave erratically for this system, with three- and four-body nonadditive terms having neither the correct sign nor magnitude. Here we analyze to what extent these qualitative errors in different MBE contributions are conveyed to post-Kohn-Sham random-phase approximation (RPA). The results reveal a correlation between the quality of the DFT input states and the RPA results. Moreover, the renormalized singles energy (RSE) corrections play a crucial role in all orders of MBE. For dimers, RSE corrects the RPA underbinding for every tested Kohn-Sham model: generalized-gradient approximation (GGA), meta-GGA, (meta-)GGA hybrids, as well as the optimized effective potential at the correlated level. Remarkably, the inclusion of singles in RPA can also correct the wrong signs of three- and four-body nonadditive energies as well as mitigate the excessive higher-order contributions to the MBE. The RPA errors are dominated by the contributions of compact clusters. As a workable method for large systems, we propose to replace those compact contributions with CCSD(T) energies and to sum up the remaining many-body contributions up to infinity with supermolecular or periodic RPA. As a demonstration of this approach, we show that for RPA(PBE0)+RSE it suffices to apply CCSD(T) to dimers and 30 compact, hydrogen-bonded trimers to get the methane-water cage interaction energy to within 1.6% of the reference value.

description: Collision-free space detection is a critical component of autonomous vehicle perception. The state-of-the-art algorithms are typically based on supervised learning. The performance of such approaches is always dependent on the quality and amount of labeled training data. Additionally, it remains an open challenge to train deep convolutional neural networks (DCNNs) using only a small quantity of training samples. Therefore, this paper mainly explores an effective training data augmentation approach that can be employed to improve the overall DCNN performance, when additional images captured from different views are available. Due to the fact that the pixels of the collision-free space (generally regarded as a planar surface) between two images captured from different views can be associated by a homography matrix, the scenario of the target image can be transformed into the reference view. This provides a simple but effective way of generating training data from additional multi-view images. Extensive experimental results, conducted with six state-of-the-art semantic segmentation DCNNs on three datasets, demonstrate the effectiveness of our proposed training data augmentation algorithm for enhancing collision-free space detection performance. When validated on the KITTI road benchmark, our approach provides the best results for stereo vision-based collision-free space detection.

description: The Hall resistivity and magnetization have been investigated in the ferromagnetic state of the bilayered manganite La(2-2x)Sr(1+2x)Mn2O7 (x=0.36). The Hall resistivity shows an increase in both the ordinary and anomalous Hall coefficients at low temperatures below 50K, a region in which experimental evidence for the spin glass state has been found in a low magnetic field of 1mT. The origin of the anomalous behavior of the Hall resistivity relevant to magnetic states may lie in the intrinsic microscopic inhomogeneity in a quasi-two-dimensional electron system.
