description: China's bilateral trade in food and agricultural products has grown dramatically since the country's entry into the World Trade Organization (WTO). However, the country faces significant problems related to sanitary and phytosanitary (SPS) compliance because of increasing concerns about food safety, stricter SPS requirements in trade, and competitiveness in export markets. China's food and agricultural industry will need to address the SPS issues and make significant changes in production and distribution methods in order to gain wider access to world markets. This study provides a systematic and comprehensive analysis of current Chinese SPS conditions, the food safety regulatory system, production environment, inspection technology, and information systems. In addition, China's progress on resolving SPS problems and ability to adjust to the current SPS measures it faces in world markets are discussed.

description: Mesh-based simulations are central to modeling complex physical systems in many disciplines across science and engineering. Mesh representations support powerful numerical integration methods and their resolution can be adapted to strike favorable trade-offs between accuracy and efficiency. However, high-dimensional scientific simulations are very expensive to run, and solvers and parameters must often be tuned individually to each system studied. Here we introduce MeshGraphNets, a framework for learning mesh-based simulations using graph neural networks. Our model can be trained to pass messages on a mesh graph and to adapt the mesh discretization during forward simulation. Our results show it can accurately predict the dynamics of a wide range of physical systems, including aerodynamics, structural mechanics, and cloth. The model's adaptivity supports learning resolution-independent dynamics and can scale to more complex state spaces at test time. Our method is also highly efficient, running 1-2 orders of magnitude faster than the simulation on which it is trained. Our approach broadens the range of problems on which neural network simulators can operate and promises to improve the efficiency of complex, scientific modeling tasks.

description: Es liegen Informationsblätter vor, die zeitnah auf unserer Universitätswebseite über ein Formularcenter zum 'Download' bereitgestellt werden sollen. Seit Januar 2020 liegen diese Informationen im Justiziariat. Forscherinnen und Forscher verlangen nach Muster-Einwilligungen und so entstand die Idee zum Thema Muster-Einwilligungen eine Coffee Lecture durchzuführen. Gerne wäre mitgeteilt worden, wo universitätsintern solche Formulare heruntergeladen werden können, aber es kann inzwischen gut auf externe Seiten verweisen werden, z.B. auf den Verbund Forschungsdaten Bildung. In meinem Alltag im FDM werde ich oft zum Datenschutz gefragt, z.B. wie lange die Forschungsdaten archiviert werden dürfen und ob die Daten während der Archivierung anonymisiert werden müssen. Forscherinnen und Forscher möchten und müssen wissen, was alles ganz genau vor der Datenerhebung beachtet werden muss. Oft erhalte ich ganz praktische Fragen, z.B. wie eine Einverständniserklärung aussehen muss und wo die Forscherinnen und Forscher Muster-Einwilligungen finden können, wer überhaupt die Verantwortung für die Einhaltung datenschutzrechtlicher Vorgaben im betreffenden Projekt trägt. Gerade in den Geistes-und Sozialwissenschaften haben wir es mit sensiblen Daten zu tun, die nicht geteilt werden dürfen („closed data”). Die internetbasierte Forschung und Datenschutz (...) (...) • stellt Sozialwissenschaftler/innen vor neue Herausforderungen • hier ist es schwierig, informierte Einwilligungen zur Teilnahme an einem Forschungsvorhaben einzuholen • der Mikro-blogging-Dienst Twitter ermöglicht es Dritten beispielsweise, mehrere tausend Nachrichten (Tweets) pro Tag auszuwerten Einwilligungen sind nur dann wirksam, wenn sie bestimmten Anforderungen des Datenschutzrechts genügen.Verlangt wird in jedem Fall eine „informierte Einwilligung“ (informed consent), weil eine wirksame Einwilligung logisch bedingt, dass der Betroffene genau weiß, in was er einwilligt. Worüber informiert werden muss, um diesen "informed consent" zu erhalten, soll es in dieser Coffee Lectures gehen, wobei Muster-Einwilligungen gezeigt werden.

description: Additive manufacturing processes show potential and utility in the construction industry by enabling new design freedoms and increasing the degree of automation. Accurate prediction of structural deformations and optimization of process parameters is a crucial consideration to ensure better component quality, reduced test effort and fewer buildability failures. This paper introduces an approach to build a nonlinear model that maps the interlayer waiting time in the building process to the corresponding structural deformation based on FEM results obtained from a process based FEM simulation. The model is utilized to optimize the interlayer waiting time during the printing process using the maximum deformation of the structure as the objective function and the allocated printing time together with the allowed maximum interlayer waiting time as constraints. Finally, the validity of the approach is numerically verified using a test component.

subject: welfare analysis

description: A framework is developed for examining the price and welfare effects of the introduction of genetically modified (GM) crops. In the short run, non-GM grain generally becomes another niche product. However, more profound market effects are observed under some reasonable parameterizations. In the long run, consumer and producer welfare are usually greater after the introduction of GM technology. Nevertheless, in all instances some consumers and some producers lose. When identity preservation is expensive and cost savings are relatively small, both producer and consumer welfare are lower after introducing GM technology. Interestingly, this outcome is obtained even though all agents are individually rational.

description: In this article we use a geometric approach to study geometric phases in graphitic cones. The spinor that describes the low energy states near the Fermi energy acquires a phase when transported around the apex of the cone, as found by a holonomy transformation. This topological result can be viewed as an analogue of the Aharonov-Bohm effect. The topological analysis is extended to a system with $n$ cones, whose resulting configuration is described by an effective defect.

Uniform Estimates in Periodic Homogenization of Fully Nonlinear Elliptic Equations

Year: 2020
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: This article is concerned with uniform $C^{1,α}$ and $C^{1,1}$ estimates in periodic homogenization of fully nonlinear elliptic equations. The analysis is based on the compactness method, which involves linearization of the operator at each approximation step. Due to the nonlinearity of the equations, the linearized operators involve the Hessian of correctors, which appear in the previous step. The involvement of the Hessian of the correctors deteriorates the regularity of the linearized operator, and sometimes even changes its oscillating pattern. These issues are resolved with new approximation techniques, which yield a precise decomposition of the regular part and the irregular part of the homogenization process, along with a uniform control of the Hessian of the correctors in an intermediate level. The approximation techniques are even new in the context of linear equations. Our argument can be applied not only to concave operators, but also to certain class of non-concave operators.

description: A theory in which 16-dimensional curved Clifford space (C-space) provides a realization of Kaluza-Klein theory is investigated. No extra dimensions of spacetime are needed: "extra dimensions" are in C-space. We explore the spin gauge theory in C-space and show that the generalized spin connection contains the usual 4-dimensional gravity and Yang-Mills fields of the U(1)xSU(2)xSU(3) gauge group. The representation space for the latter group is provided by 16-component generalized spinors composed of four usual 4-component spinors, defined geometrically as the members of four independent minimal left ideals of Clifford algebra.

description: China and India are two of the world's biggest countries and potentially large markets for U.S. agricultural products. This study reports the assessment by midwestern agricultural firms of doing business in the two countries. The data, collected by mail questionnaire, suggests that China posed less of a problem than did India with respect to economic and market conditions, tariff and investment barriers, and physical and cultural barriers. On the other hand, India posed less of a problem than did China with respect to language, protection of property rights, and the legal system. Firms already doing business in these countries had more favorable comments than those with no previous experience. The study also reports results of telephone interviews with selected firms. These conversations provide a more personal account of challenges faced by firms that are testing markets in the two countries.
Learning and avoiding disorder in multimode fibers

description: Multimode optical fibers (MMFs) have gained renewed interest in the past decade, emerging as a way to boost optical communication data-rates in the context of an expected saturation of current single-mode fiber-based networks. They are also attractive for endoscopic applications, offering the possibility to achieve a similar information content as multicore fibers, but with a much smaller footprint, thus reducing the invasiveness of endoscopic procedures. However, these advances are hindered by the unavoidable presence of disorder that affects the propagation of light in MMFs and limits their practical applications. We introduce here a general framework to study and avoid the effect of disorder. We experimentally find an almost complete set of optical channels that are resilient to disorder induced by strong deformations. These deformation principle modes are obtained by only exploiting measurements for weak perturbations. We explain this effect by demonstrating that, even for a high level of disorder, the propagation of light in MMFs can be characterized by just a few key properties. These results are made possible thanks to a precise and fast estimation of the modal transmission matrix of the fiber which relies on a model-based optimization using deep learning frameworks.

description: We provide a systematic and comprehensive derivation of the linearized dynamics of massive and partially massless spin-2 particles in a Schwarzschild (anti) de Sitter black hole background, in four and higher spacetime dimensions. In particular, we show how to obtain the quadratic actions for the propagating modes and recast the resulting equations of motion in a Schrödinger-like form. In the case of partially massless fields in Schwarzschild de Sitter spacetime, we study the isospectrality between modes of different parity. In particular, we prove isospectrality analytically for modes with multipole number $L=1$ in four spacetime dimensions, providing the explicit form of the underlying symmetry. We show that isospectrality between partially massless modes of different parity is broken in higher-dimensional Schwarzschild de Sitter spacetimes.

description: Thick GEM-like (THGEM) gaseous electron multipliers are made of standard printed-circuit board perforated with sub-millimeter diameter holes, etched at their rims. Effective gas multiplication factors of 100000 and 10000000 and fast pulses in the few nanosecond rise-time scale were reached in single- and cascaded double-THGEM elements, in atmospheric-pressure standard gas mixtures with single photoelectrons. High single-electron detection efficiency is obtained in photon detectors combining THGEMs and semitransparent UV-sensitive CsI photocathodes or reflective ones deposited on the top THGEM face; the latter benefits of a reduced sensitivity to ionizing background radiation. Stable operation was recorded with photoelectron fluxes exceeding MHz/mm2. The properties and some potential applications of these simple and robust multipliers are discussed.

description: Virtual machine (VM) scheduling in a dynamic cloud environment is often bound with multiple quality of service parameters; therefore, it is classed as an NP-hard optimization problem. Swarm-based metaheuristics, such as the whale optimization algorithm (WOA), have gained a notable reputation for solving optimization problems. The unique bubble-net hunting behaviour and fast convergence of the algorithm led to the development of a hybrid multi-objective whale optimization algorithm-based differential evolution (M-WODE) technique to solve the VM scheduling problem. The differential evolution (DE) strategy is used to replace the randomly generated solution produced by the WOA to ensure diversity in the solution and to strengthen the local search of the M-WODE. In addition, the DE technique is applied to the Pareto front produced by the WOA to escape local optima entrapment problems. The experimental results showed that the proposed M-WODE outperformed previous algorithms in most cases on makespan and the cost trade-off.
Production of muons from heavy-flavour hadron decays at high transverse momentum in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ and 2.76 TeV

description: Measurements of the production of muons from heavy-flavour hadron decays in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = $5.02$ and $2.76$ TeV using the ALICE detector at the LHC are reported. The nuclear modification factor $R_{\rm AA}$ at $\sqrt{s_{\rm NN}}$ = 5.02 TeV is measured at forward rapidity ($2.5 < y <4$) as a function of transverse momentum $p_{\rm T}$ in central, semi-central, and peripheral collisions over a wide $p_{\rm T}$ interval, $3 < p_{\rm T} < 20$ GeV/$c$, in which muons from beauty-hadron decays are expected to take over from charm as the dominant source at high $p_{\rm T}$ ($p_{\rm T} > 7$ GeV/$c$). The $R_{\rm AA}$ shows an increase of the suppression of the yields of muons from heavy-flavour hadron decays with increasing centrality. A suppression by a factor of about three is observed in the $10\%$ most central collisions. The $R_{\rm AA}$ at $\sqrt{s_{\rm NN}}$ = 5.02 is similar to that at 2.76 TeV. The precise $R_{\rm AA}$ measurements have the potential to distinguish between model predictions implementing different mechanisms of parton energy loss in the high-density medium formed in heavy-ion collisions. They place important constraints for the understanding of the heavy-quark interaction with the hot and dense QCD medium.

Most are based on an interaction between the ions and external optical fields, coupling internal qubit states of trapped-ions to their Coulomb-coupled motion. In this paper, we examine the sensitivity of these motional gate schemes to phase fluctuations introduced through noisy external control fields, and suggest techniques to suppress the resulting phase decoherence.

description: We review the present status of quantum-gravity phenomenology in relation to gravitational waves (GWs). The topic can be approached from two direction, a model-dependent one and a model-independent one. In the first case, we introduce some among the most prominent cosmological models embedded in theories of quantum gravity, while in the second case we point out certain common features one finds in quantum gravity. Three cosmological GW observables can be affected by perturbative as well as non-perturbative quantum-gravity effects: the stochastic GW background, the propagation speed of GWs and the luminosity distance of GW sources. While many quantum-gravity models do not give rise to any observable signal, some predict a blue-tilted stochastic background or a modified luminosity distance, both detectable by future GW interferometers. We conclude that it is difficult, but still possible, to test quantum gravity with GW observations.

description: This paper examines the incentive of atomistic agricultural producers within a specific geographical region to differentiate and collectively market products. We develop a model that allows us to analyze the market and welfare effects of the main types of real-world producer organizations, using it to derive economic insights regarding the circumstances under which these organizations will evolve, and describing implications of the results obtained in the context of an ongoing debate between the European Union and United States. As the anticipated fixed costs of development and marketing increase and the anticipated size of the market falls, it becomes essential to increase the ability of the producer organization to control supply in order to ensure the coverage of fixed costs. Whenever a collective organization allows a market (with a new product) to exist that otherwise would not have existed there is an increase in societal welfare. Counterintuitively, stronger property right protection for producer organizations may be welfare enhancing even after a differentiated product has been developed. The reason for this somewhat paradoxical result is that legislation aimed at curtailing the market power of producer organizations may induce large technological distortions.

description: In an attempt to understand better Brazil's future role in agricultural markets, the authors of this report traveled to Brazil on a fact-finding mission in September 2003. The goal was to get a first-hand impression of Brazil's agricultural sector and especially its future potential. In this report we provide a general description of crop and livestock production, government policies, public and private cooperation, and transportation and biotechnology issues. The most striking observations made during our time in Brazil was the universal sense of optimism expressed by producers, government officials, agronomists, and market analysts about the future growth of Brazilian agricultural production. Does that mean Brazil, as one person suggested, is the future of modern agriculture? Our answer to that question depends on one's view of the future of global agriculture. Brazilian large-scale, commercially oriented, forward-looking operations are well suited to compete in commodity markets that are constantly driven to increase productivity and reduce costs. On the other hand, we observed factors within Brazil itself that have potential for creating tensions, which may ultimately force politicians to consider reforms that reduce production efficiency to achieve other social and environmental objectives.

description: Shape optimization is a pervasive tool for designing concrete free-form shells. However, the existing shape optimization approaches for free-form shells usually assume the material is purely elastic without considering material damage, which may produce undesired results in real-world structural applications, especially in the case of concrete structures. In this article, a framework is presented for performing the shape optimization of concrete free-form shells while considering concrete damage. In the proposed optimization algorithm, the Mazars model is coupled with finite element analysis for modelling structural responses subjected to material damage. Through a series of numerical examples, the proposed algorithm is validated and the effects of material damage on optimal results are investigated. It is demonstrated that the consideration of material damage leads to a more robust design, which highlights the importance of accounting for the material damage during the shape optimization process of concrete free-form shells.

description: Yaws-like lesions are widely reported in wild African great apes, yet the causative agent has not been confirmed in affected animals. We describe yaws-like lesions in a wild chimpanzee in Guinea for which we demonstrate infection with Treponema pallidum subsp. pertenue. Assessing the conservation implications of this pathogen requires further research.

description: In an analysis of the gravitational lensing by two relativistic cosmic strings, we argue that the formation of closed time-like curves proposed by Gott is unstable in the presence of particles (e.g. the cosmic microwave background radiation). Due to the attractor-like behavior of the closed time-like curve, we argue that this instability is very generic. A single graviton or photon in the vicinity, no matter how soft, is sufficient to bend the strings and prevent the formation of closed time-like curves. We also show that the gravitational lensing due to a moving cosmic string is enhanced by its motion, not suppressed.

THE 3 Rs OF STRATEGIC ALLIANCE FORMATION: RESOURCES, RENTS, AND (PROPERTY) RIGHTS

description: This paper examines the formation and governance of strategic alliances. In particular, the problem is defined for the development of alliances in agriculture, where new organizational forms are arising rapidly for horizontal and vertical coordination of the production-marketing chain. As the title of this research conference implies, these organizational forms offer opportunities within the portfolio of strategies facing agricultural producers for reconfiguring their marketing and managing risks by joint/collective action. The basis for the paper is the resource-based theory (RBT) of firm strategy, which has developed over the past ten years as a way to build positive and normative models of strategic decisions. The RBT draws from industrial organization economics and organizational economics (often called neoinstitutional economics) as a way to model the sources and robustness of sustainable competitive advantage. This paper extends to RBT to the joint strategies of firms engaged in strategic alliances. Additionally, the analysis turns on the manner by which economic rents are earned in a strategic alliance and how they are shared by alliance partners. What rights do alliance partners have to jointly earned returns in the alliance, given its organizational form (statutory structure and governance structure), the sources of economic rents, risks associated with the rent streams, and the often intangible resources (assets) that drive the performance of the joint assets in the alliance? This discussion paper presents a brief review of the RBT model, followed by a discussion of the sources of, and durability of, economic rents that accrue to firm resources. These sections are essentially résumés of the current literature on RBT. The third section departs from the literature in explicitly considering a model of strategic alliance formation as the development of a portfolio of jointly held alliance resources that are linked to the resource portfolios of the individual alliance partners. The fourth section presents further extensions of RBT to examine the problems of ex ante and ex post division of alliance rents. One extension is the exploitation of the property rights theory of economic behavior (cf. Barzel, 1989) to explain how the economic rent streams from the resource portfolio should be shared among alliance partners, including participating financial institutions.

description: We study the Replica Symmetric region of general multi-species Sherrington-Kirkpatrick (MSK) Model and answer some of the questions raised in Ann.~Probab.~43~(2015), no.~6, 3494--3513, where the author proved the Parisi formula under \emph{positive-definite} assumption on the disorder covariance matrix $Δ^2$. First, we prove exponential overlap concentration at high temperature for both \indf~and \emph{positive-definite} $Δ^2$ MSK model. We also prove a central limit theorem for the free energy using overlap concentration. Furthermore, in the zero external field case, we use a quadratic coupling argument to prove overlap concentration up to $β_c$, which is expected to be the critical inverse temperature. The argument holds for both \emph{positive-definite} and emph{indefinite} $Δ^2$, and $β_c$ has the same expression in two different cases. Second, we develop a species-wise cavity approach to study the overlap fluctuation, and the asymptotic variance-covariance matrix of overlap is obtained as the solution to a matrix-valued linear system. The asymptotic variance also suggests the de Almeida--Thouless (AT) line condition from the Replica Symmetry (RS) side. Our species-wise cavity approach does not require the positive-definiteness of $Δ^2$. However, it seems that the AT line conditions in \emph{positive-definite} and \emph{indefinite} cases are different. Finally, in the case of \emph{positive-definite} $Δ^2$, we prove that above the AT line, the MSK model is in Replica Symmetry Breaking phase under some natural assumption. This generalizes the results of J.~Stat.~Phys.~174 (2019), no.~2, 333--350, from 2-species to general species.

description: Η αντιμετώπιση στον COVID-19 δεν περιλαμβάνει μόνο τη θωράκιση των θέσεων εργασίας στις επιχειρήσεις, την υποστήριξη της επιχειρηματικότητας και την αύξηση του δημόσιου χρέους, αλλά και τη δημιουργία παραγωγικής επιχειρηματικότητας και ανθεκτικών επιχειρηματικών πλαισίων. Η πανδημία του COVID-19 είναι μια άνευ προηγουμένου πρόκληση για τις επιχειρήσεις που φέρνει επίσης νέες ευκαιρίες στην αγορά. Μάλιστα, η πανδημία έχει επηρεάσει σημαντικά τις ευρωπαϊκές και μη ευρωπαϊκές επιχειρήσεις. Εκατομμύρια επιχειρήσεις έχουν χάσει τα προγραμματισμένα έσοδά τους και εκατομμύρια θέσεις εργασίας έχουν εξαφανιστεί. Ο οικονομικός μηχανισμός δεν επιτρέπει τον τερματισμό των διαδικασιών χωρίς επιπτώσεις στο μέλλον και όταν σταματήσει η οικονομία, πολλοί επιχειρηματικοί κύκλοι σταματούν, προσωρινά ή μόνιμα. Ως συνονθύλευμα των ανωτέρω αναπόφευκτα επηρεάζεται η διοίκηση ανθρώπινου προσωπικού και η απόδοση των εργαζομένων, καθώς οι επιχειρήσεις προκειμένου να διατηρήσουν την βιωσιμότητα τους, έπρεπε να λάβουν δραστικές αποφάσεις και να κάνουν χρήση ποικίλων μεθόδων και τεχνικών, με την πιο διαδεδομένη την εξ’ αποστάσεως εργασία. Στη παρούσα εργασία θα μελετηθεί το ζήτημα της διοίκησης ανθρώπινου δυναμικού και πως επιδρά στην απόδοση των εργαζομένων με ιδιαίτερη μνεία στις επιπτώσεις της πανδημίας τόσο στις επιχειρήσεις όσο και στην οικονομία.

description: We introduce a protocol for a quantum switch in the gravitational field of a spherical mass and determine the time interval required for its realization in the gravity of Earth. One of the agents that perform operations with indefinite order is a quantum system in a path superposition state. Entanglement between its proper time and position is explored as a resource for the implementation of the quantum switch. The realization of the proposed protocol would probe the physical regime described by quantum mechanics on curved spacetimes, which has not yet been explored experimentally.

description: In two-dimensional space a subtle point that for the case of both space-space and momentum-momentum noncommuting, different from the case of only space-space noncommuting, the deformed Heisenberg-Weyl algebra in noncommutative space is not completely equivalent to the undeformed Heisenberg-Weyl algebra in commutative space is clarified. It follows that there is no well defined procedure to construct the deformed position-position coherent state or the deformed momentum-momentum coherent state from the undeformed position-momentum coherent state. Identifications of the deformed position-position and deformed momentum-momentum coherent states with the lowest energy states of a cold Rydberg atom in special conditions and a free particle, respectively, are demonstrated.

description: We present results on THGEM operation at low gas pressures, in the range 0.5-50 Torr. Gaseous gain up to 100000 was recorded at 10 Torr of Isobutane in a single multiplier element, with pulses rise-time in the few ns range. Cascaded operation of two THGEMs is reported, with similar total gain but at lower voltages on each element. The present work encompasses a large variety of THGEM geometries and includes electric-field distribution calculations and electron transport simulations. We discuss the operation mechanism and some possible applications of THGEMs at low gas pressures.

The experience and transformation of the Hanoi Chinese Middle School, 1954-1968
Creators: name: Lai, Janet
Publisher: name: University of British Columbia
Year: 2009

description: The Hanoi Chinese Middle School was the only secondary school for ethnic Chinese students in Hanoi, North Vietnam. Its vicissitude from 1954 to 1968 coincided with the relationship between the Beijing and Hanoi governments and the escalation of the Vietnam War. Based on the recollections of 19 alumni, it is possible to trace the gradual Vietnamisation of the school and the personal conflict and upheaval that resulted from the process of trying to make the ethnic Chinese students more 'Vietnamese' and how this process was affected by war with the Americans.

description: The idea of using Feed-Forward Neural Networks (FFNNs) as regression functions for Nonlinear AutoRegressive eXogenous (NARX) models, leading to models herein named Neural NARXs (NNARXs), has been quite popular in the early days of machine learning applied to nonlinear system identification, owing to their simple structure and ease of application to control design. Nonetheless, few theoretical results are available concerning the stability properties of these models. In this paper we address this problem, providing a sufficient condition under which NNARX models are guaranteed to enjoy the Input-to-State Stability (ISS) and the Incremental Input-to-State Stability (δISS) properties. This condition, which is an inequality on the weights of the underlying FFNN, can be enforced during the training procedure to ensure the stability of the model. The proposed model, along with this stability condition, are tested on the pH neutralization process benchmark, showing satisfactory results.
