description: As China has become an increasingly important part of the global trading system over the past two
decades, interest in the country and its international economic policies has increased among
international economists who are not China specialists. This paper represents an attempt to provide
the international economics community with a succinct summary of the major steps in the evolution
of Chinese policy toward international trade and foreign direct investment and their consequences
since the late 1970s. In doing so, we draw upon and update a number of more comprehensive
book-length treatments of the subject. It is our hope that this paper will prove to be a useful resource
for the growing numbers of international economists who are exploring China-related issues, either
in the classroom or in their own research.

description: Compressed sensing (CS) model of complex-valued data can represent the signal recovery process of a large amount types of radar systems, especially when the measurement matrix is row-orthogonal. Based on debiased least absolute shrinkage and selection operator (LASSO), detection problem under Gaussian random design model, i.e. the elements of measurement matrix are drawn from Gaussian distribution, is studied by literature. However, we find that these approaches are not suitable for row-orthogonal measurement matrices, which are of more practical relevance. In view of statistical mechanics approaches, we provide derivations of more accurate test statistics and thresholds (or p-values) under the row-orthogonal design model, and theoretically analyze the detection performance of the present detector. Such detector can analytically provide the threshold according to given false alarm rate, which is not possible with the conventional CS detector, and the detection performance is proved to be better than that of the traditional LASSO detector. Comparing with other debiased LASSO based detectors, simulation results indicate that the proposed approach can achieve more accurate probability of false alarm when the measurement matrix is row-orthogonal, leading to better detection performance under Neyman-Pearson principle.

description: In consequence of the technological advances of the last few decades, factories emerged to highly complex systems that consist of numerous factory elements like production machines, technical building services and the building shell. These factory elements are characterized by individual life cycles that differ in their duration and life cycle behavior. Consequently, the factory life cycle is composed of multiple overlapping life cycles. The fact that the life cycle of some factory elements (e.g. the building shell) exceeds the life cycle of other elements over many times (e.g. of machines) presents a challenge for factory planners. In particular, factory planners struggle to understand the contribution of single factory elements on the total factory life cycle. Consequently, it is hard to systematically synchronize the inherent life cycles of a factory while adhering to manifold requirements. Against this background, the goal of this paper is to develop a methodology that supports factory planners in the evaluation of the factory life cycle. The proposed methodology enhances the understanding of how factory elements contribute to the factory life cycle and what is the current life cycle state of the entire factory. To this end, the factory system is broken down on its constituting elements. A modified failure mode and effect analysis (FMEA) is applied to assess their life cycle priority according to economic, environmental and technical criteria. The methodology is exemplarily demonstrated on a pilot scale battery production system.

description: Current electric vehicle battery recycling processes often begin with the manual dismantling of the battery packs. In consideration of occupational safety and in view of the increasing sales of electric vehicles, an automated dismantling of batteries has to be investigated. Therefore, different manufacturers' battery pack designs are examined first and especially the common joining elements are determined and characterized. The results show a high diversity between the individual systems, which influences the potential for automation. Based on these investigations, a possible layout of an automated dismantling cell is developed.

description: Bilayers of two-dimensional materials twisted at specific angles can exhibit exceptional properties such as the occurrence of unconventional superconductivity in twisted graphene. We demonstrate here that novel phenomena in twisted materials emerges also in particle-based classical systems. We study the transport of magnetic colloidal particles driven by a drift force and located between two twisted periodic magnetic patterns with either hexagonal or square symmetry. The magnetic potential generated by patterns twisted at specific magic angles develops flat channels, which increase the mobility of the colloidal particles compared to that in single patterns. We characterize the effect of the temperature and that of the magnitude of the drift force on the colloidal mobility. The transport is more enhanced in square than in hexagonal twisted patterns. Our work extends twistronics to classical soft matter systems with potential applications to lab-on-a-chip devices.
Single-Valued Killing Fields of a Meromorphic Affine Connection and Classification

Publisher: name: arXiv
Year: 2022
Subjects: subject: Complex Variables (math.CV)
subject: FOS: Mathematics

description: We give a geometric condition on a meromorphic affine connection for its Killing vector fields to be single valued. More precisely, this condition relies on the pole of the connection and its geodesics, and defines a subcategory. To this end, we use the equivalence between these objects and meromorphic affine Cartan geometries. The proof of the previous result is then a consequence of a more general result linking the distinguished curves of meromorphic Cartan geometries, their poles and their infinitesimal automorphisms, which is the main purpose of the paper. This enables to extend the classification result from [Biswas I., Dumitrescu S., McKay B., Épijournal Géom. Algèbrique 3 (2019), 19, 10 pages, arXiv:1804.08949] to the subcategory of meromorphic affine connection described before.

description: In markets that exhibit network effects, the presence of digital conversion technologies provides an alternative mechanism to achieve compatibility. This study examines the impact of conversion technologies on market equilibrium in the context of sequential duopoly competition and proprietary technology standards.
We analyze this question by departing from the extant literature to endogenize the decision to provide a converter and incorporate explicit negotiations between firms concerning the extent of conversion. We argue that these choices better reflect the environment facing firms in digital goods industries and find that these decisions change some of the established results in the literature.
Specifically, we find that unless network effects are very large, the subgame perfect equilibrium involves firms’ agreeing to provide digital converters at a sufficiently low price to all consumers. At this equilibrium, both the entrant and the incumbent are better off since the provision of converters alleviates price competition in the market and leads to both higher product revenues and higher proceeds from the sale of converters. Moreover, under some circumstances the provision of converters is welfare enhancing.
These findings have important implications for research and practice in the adoption of new digital goods as the introduction of conversion technologies can reduce the social costs of standardization without compromising the benefits of network effects.

description: Ebolavirus (EBOV) infection in humans is a severe and often fatal disease, which demands effective interventional strategies for its prevention and treatment. The available vaccines, which are authorized under exceptional circumstances, use viral vector platforms and have serious disadvantages, such as difficulties in adapting to new virus variants, reliance on cold chain supply networks, and administration by hypodermic injection. Microneedle (MN) patches, which are made of an array of micron-scale, solid needles that painlessly penetrate into the upper layers of the skin and dissolve to deliver vaccines intradermally, simplify vaccination and can thereby increase vaccine access, especially in resource-constrained or emergency settings. The present study describes a novel MN technology, which combines EBOV glycoprotein (GP) antigen with a polyphosphazene-based immunoadjuvant and vaccine delivery system (poly[di(carboxylatophenoxy)phosphazene], PCPP). The protein-stabilizing effect of PCPP in the microfabrication process enabled preparation of a dissolvable EBOV GP MN patch vaccine with superior antigenicity compared to a non-polyphosphazene polymer-based analog. Intradermal immunization of mice with polyphosphazene-based MN patches induced strong, long-lasting antibody responses against EBOV GP, which was comparable to intramuscular injection. Moreover, mice vaccinated with the MN patches were completely protected against a lethal challenge using mouse-adapted EBOV and had no histologic lesions associated with ebolavirus disease.

description: An approach based on combined solutions of the Bethe-Salpeter (BS) and Dyson-Schwinger (DS) equations within the ladder-rainbow approximation in the presence of singularities is proposed to describe the meson spectrum as quark antiquark bound states. We consistently implement into the BS equation the quark propagator functions from the DS equation, with and without pole-like singularities, and show that, by knowing the precise positions of the poles and their residues, one is able to develop reliable methods of obtaining finite interaction BS kernels and to solve the BS equation numerically. We show that, for bound states with masses $M < 1$ GeV, there are no singularities in the propagator functions when employing the infrared part of the Maris-Tandy kernel in truncated BS-DS equations. For $M >1 $ GeV, however, the propagator functions reveal pole-like structures. Consequently, for each type of mesons (unflavored, strange and charmed) we analyze the relevant intervals of $M$ where the pole-like singularities of the corresponding quark propagator influence the solution of the BS equation and develop a framework within which they can be consistently accounted for. The BS equation is solved for pseudo-scalar and vector mesons. Results are in a good agreement with experimental data. Our analysis is directly related to the future physics programme at FAIR with respect to open charm degrees of freedom.

description: We examine the Si(111) multi-valley quantum Hall system and show that it exhibits an exceptionally rich interplay of broken symmetries and quantum Hall ordering already near integer fillings $ν$ in the range $ν=0-6$. This six-valley system has a large $[SU(2)]^3\rtimes D_3$ symmetry in the limit where the magnetic length is much larger than the lattice constant. We find that the discrete ${D}_3$ factor breaks over a broad range of fillings at a finite temperature transition to a discrete nematic phase. As $T \rightarrow 0$ the $[SU(2)]^3$ continuous symmetry also breaks: completely near $ν=3$, to a residual $[U(1)]^2\times SU(2)$ near $ν=2$ and $4$ and to a residual $U(1)\times [SU(2)]^2$ near $ν=1$ and $5$. Interestingly, the symmetry breaking near $ν=2,4$ and $ν=3$ involves a combination of selection by thermal fluctuations known as "order by disorder" and a selection by the energetics of Skyrme lattices induced by moving away from the commensurate fillings, a mechanism we term "order by doping". We also exhibit modestly simpler analogs in the four-valley Si(110) system.

O ensino religioso em Franz Rosenzwieg

description: Frente a discussão que se apresenta sobre “Ensino de Religião”, essa comunicação pretende propor uma reflexão a partir do pensador Franz Rosenzweig (1886-1929). Partindo do pressuposto que a religião se dá na experiência concreta, Rosenzweig terá como preocupação principal o ensino religioso, o que transforma uma possível teoria da religião em uma pedagogia da religião, pois, para ele, compreender judaísmo é praticar judaísmo. O objetivo de Rosenzweig não é validar o judaísmo – a religião. É a experiência pessoal que funda seu pensamento e esta experiência é expressa na linguagem do judaísmo.

description: Energy efficiency is an essential factor for promoting sustainable manufacturing. Various types of energy consumption occur in modern process chains. This includes usage of electrical energy, e.g. for machine tools or air compression, but also energy consumption through use of resources (such as raw materials and supplies). In this paper, a process chain from the automotive industry is considered with the purpose of identifying energy saving potentials of various kinds. The process chain is used for the production of an axle component. In order to evaluate saving potentials, the current state of the process chain is analyzed. Then, the impact of process parameter optimization on the energy demand is examined. It was found that small energy savings through parameter optimization are possible. However, this can be problematic since process parameters are closely linked to process reliability, so energy savings might be achieved at the expense of product quality. Furthermore, it turns out that the reduction of the process energy is not sufficient for a broad energetic optimization of the process chain and base load reducing measures are required instead. Therefore, further analysis is focused on energetic effects of such measures as machine design, recycling, adjustments of process chain and product design. These were found to be an effective lever for minimizing energy demand of the process chain. A combination of feasible measures adds up to a potential energy saving of 11.5% in the investigated scenario.

description: We use a network model of credit risk to measure market expectations of the potential spillovers from a sovereign default. Specifically, we develop an empirical model, based on the recent theoretical literature on contagion in financial networks, and estimate it with data on sovereign credit default swap spreads and the detailed structure of financial linkages among thirteen European sovereigns from 2005 to 2011. Simulations from the estimated model show that a sovereign default generates only small spillovers to other sovereigns. These results imply that credit markets do not demand a significant premium for the interconnectedness of sovereign debt in Europe.

description: Models for which the likelihood function can be evaluated only up to a parameter-dependent unknown normalising constant, such as Markov random field models, are used widely in computer science, statistical physics, spatial statistics, and network analysis. However, Bayesian analysis of these models using standard Monte Carlo methods is not possible due to the intractability of their likelihood functions. Several methods that permit exact, or close to exact, simulation from the posterior distribution have recently been developed. However, estimating the evidence and Bayes' factors (BFs) for these models remains challenging in general. This paper describes new random weight importance sampling and sequential Monte Carlo methods for estimating BFs that use simulation to circumvent the evaluation of the intractable likelihood, and compares them to existing methods. In some cases we observe an advantage in the use of biased weight estimates. An initial investigation into the theoretical and empirical properties of this class of methods is presented. Some support for the use of biased estimates is presented, but we advocate caution in the use of such estimates.

description: eer-ratings have become increasingly important sources of product information, particularly in markets for "information goods." However, in spite of the increasing prevalence of this information, there are relatively few academic studies that analyze the impact of peer-ratings on consumers transacting in "real world" marketplaces. In this paper, we partner with a major cable company to analyze the impact of peer-ratings in a real-world Video-on-Demand market where consumer participation is organic and where movies are costly and well-known to consumers. After experimentally manipulating the initial conditions of product information displayed to consumers, we find that, consistent with the prior literature, peer-ratings influence consumer behavior independently from underlying product quality. However, we also find that, in contrast to the prior literature, at least in our setting there is little evidence of long-term bias due to herding effects. Specifically, when movies are artificially promoted or demoted in peer-rating lists, subsequent reviews cause them to return to their true quality position relatively quickly. One explanation for this difference is that consumers in our empirical setting likely had more outside information about the true quality of the products they were evaluating than did consumers in the studies reported in prior literature. While tentative, this explanation suggests that in real-world marketplaces where consumers have sufficient access to outside information about true product quality, peer-ratings may be more robust to herding effects and thus provide more reliable signals of true product quality, than previously thought.

description: This paper reports the discovery of a series of computational social media accounts (Fanbots) on Twitter that may have played a critical role in sustaining the entrepreneurial narratives of Tesla, the electric-vehicle maker. From 2010 to 2020—a period of trial, error, and eventual success for Tesla—these computational agents generated pro-firm tweets (Corporate Computational Propaganda, CCP), accounting for more than 10% of the total Twitter activity that included the cashtag, $TSLA, and 23% of activity that included the hashtag, #TSLA. Though similar to programmed social media content in the political sphere, the activities of these accounts predate the existence of political computational propaganda associated with foreign support for, for instance, Brexit in the United Kingdom (2016) and Donald Trump in the United States (2016). The paper (a) characterizes the extent of Fanbot content in two large Tesla tweet corpora, (b) identifies possible motivations for the creation of these accounts in relation to the firm’s entrepreneurial narratives, and (c) explores possible mechanisms by which the Fanbots might have acted. Although we are unable to directly observe the source or stated purpose of these accounts, based upon the timing of Fanbot creation and other indirect indicators, we infer that these accounts and the social media activity they generated were intended to influence social perception of Tesla. The conclusion assesses the generalizability of a Fanbot-based strategy, highlighting contextual limitations, while also pointing to ways that firms may already be using CCP to manage social approval in emerging-industry contexts.

description: Luciano Carta, dopo la pubblicazione degli atti parlamentari del periodo rivoluzionario (L’attività degli Stamenti della Sarda Rivoluzione (1793-1794), a cura di Luciano Carta, 4 voll., Consiglio Regionale
della Sardegna-Edicos, Cagliari, 2000), giunti a coronamento di una vita dedicata alla ricerca storica e, in particolare, al Settecento sardo, offre un completo quadro d’insieme di uno tra i secoli più significativi
del confronto tra tradizione e innovazione, tra conservazione e riformismo, che la storia sarda possa annoverare.
Il testo è un itinerario guidato nelle conoscenze e interpretazioni ormai criticamente acquisite e nella relativa bibliografia principale, ma anche in quelle che necessitano di ulteriori indagini e di nuovi sforzi ermeneutici. Nel contempo è anche una guida alla ricca storiografia di settore, intessuta di sapienza metodologica e di passione politica che riesce a illuminare, in controluce, non solo la materia dell’oggetto storico studiato, ma anche la cultura degli uomini e degli ambienti che lo hanno scandagliato.

description: This essay reviews the evidence on the deterrent effect of police, imprisonment, and capital punishment and in addition summarizes knowledge of sanction risk perceptions. Studies of changes in police presences, whether achieved by changes in police numbers or in their strategic deployment, consistently find evidence of deterrent effects. Studies of the deterrent effect of increases in already long prison sentences find at most a modest deterrent effect. Studies of the deterrent effect of capital punishment provide no useful information on the topic. Four high priority areas for future research are identified: developing and testing an integrated model of the effects of the threat and experience of punishment, measuring perceptions of sanction regimes, developing and testing a theory of criminal opportunities, and estimating the deterrent effect of shorter prison sentences and identifying high- deterrence policies.

description: Introduction: Access to augmentative and alternative communication (AAC) systems in languages other than English and multilingual AAC systems remains limited for many people with complex communication needs, despite a growing interest in this field, and an acknowledged need for culturally responsive AAC practice. Purpose: The purpose of this scoping review was to identify published research that has reported on the development of components or whole AAC systems in languages other than English, and the linguistic and cultural factors that influenced research methods and AAC system development. Method: Nine databases were systematically searched for published research that presented development of components or whole AAC systems in languages other than English. The Mixed Methods Appraisal Tool was used to assess the quality of studies. Charted data from studies included journal and publication date, research team, language of AAC system, aims of the study, study methodologies, study participants, and type of AAC systems developed. An analytical framework was developed to identify the cultural and linguistic factors that influenced research methods and or AAC system outcomes. Results: A total of 22 studies were included (13 qualitative, one quantitative nonrandomized, six quantitative descriptive, and two mixed-methods studies). Overall quality of studies was high. Some qualitative studies were of lower quality due to limited analysis or interpretation of results. Linguistic factors were extensively reported in the existing literature, whereas cultural factors were rarely explicitly reported. Conclusion: Factors contributing to lack of reporting of cultural considerations are posited with suggestions for future research. Supplemental Material S1.

A Uniquely Solvable, Positivity-Preserving and Unconditionally Energy Stable Numerical Scheme for the Functionalized Cahn-Hilliard Equation with Logarithmic Potential

description: We propose and analyze a first-order finite difference scheme for the functionalized Cahn-Hilliard (FCH) equation with a logarithmic Flory-Huggins potential. The semi-implicit numerical scheme is designed based on a suitable convex-concave decomposition of the FCH free energy. We prove unique solvability of the numerical algorithm and verify its unconditional energy stability without any restriction on the time step size. Thanks to the singular nature of the logarithmic part in the Flory-Huggins potential near the pure states $\pm 1$, we establish the so-called positivity-preserving property for the phase function at a theoretic level. As a consequence, the numerical solutions will never reach the singular values $\pm 1$ in the point-wise sense and the fully discrete scheme is well defined at each time step. Next, we present a detailed optimal rate convergence analysis and derive error estimates in $l^{\infty}(0,T;L_h^2)\cap l^2(0,T;H^3_h)$ under a linear refinement requirement $Δt\leq C_1 h$. To achieve the goal, a higher order asymptotic expansion (up to the second order temporal and spatial accuracy) based on the Fourier projection is utilized to control the discrete maximum norm of solutions to the numerical scheme. We show that if the exact solution to the continuous problem is strictly separated from the pure states $\pm 1$, then the numerical solutions can be kept away from $\pm 1$ by a positive distance that is uniform with respect to the size of the time step and the grid. Finally, a few numerical experiments are presented. Convergence test is performed to demonstrate the accuracy and robustness of the proposed numerical scheme. Pearling bifurcation, meandering instability and spinodal decomposition are observed in the numerical simulations.

description: The alarming increase in lethal violence among young people in the U.S.-which is often attributed to drug use and drug trafficking-has prompted re-examination of the relationship between drugs and violent offending. While no national data exist, numerous local studies find a high prevalence of homicide deaths among identified drug addicts, a high prevalence of substance use-typically alcohol-among victims of homicide, and a high proportion of persons testing positive for drug use among arrestees for violent offenses. Other studies report large increases in drug-related homicides or other violence associated with drug distribution. In a departure from previous research that contrasts users and nonusers of drugs, or compares broad periods of heavy and light drug use during long addiction careers, the present study attempts to isolate more direct effects of drug use near the time of offending. The data are for a sample of adults arrested in Washington, DC from July 1, 1985 to June 30, 1986, and include their longitudinal arrest histories along with the results of urine drug screens administered following arrest.

description: Pickering emulsions stabilized by TEMPO-oxidized chitin nanocrystals (T-ChNCs) were developed for quercetin delivery. T-ChNCs were synthesized by TEMPO oxidation chitin and systematically characterized in terms of their physicochemical properties. T-ChNCs were rod-like with a length of 279.7 ± 11.5 nm and zeta potential around −56.1 ± 1.6 mV. The Pickering emulsions were analyzed through an optical microscope and CLSM. The results showed that the emulsion had a small droplet size (972.9 ± 86.0 to 1322.3 ± 447.7 nm), a high absolute zeta potential value (−48.2 ± 0.8 to −52.9 ± 1.9 mV) and a high encapsulation efficiency (quercetin: 79.6%). The emulsion stability was measured at different levels of T-ChNCs and pH values. The droplet size and zeta potential decreased with longer storage periods. The emulsions formed by T-ChNCs retarded the release of quercetin at half rate of that of the quercetin ethanol solution. These findings indicated that T-ChNCs are a promising candidate for effectively stabilizing Pickering emulsions and controlling release of quercetin.

description: Automatic image annotation is one of the most challenging problems in machine vision areas. The goal of this task is to predict number of keywords automatically for images captured in real data. Many methods are based on visual features in order to calculate similarities between image samples. But the computation cost of these approaches is very high. These methods require many training samples to be stored in memory. To lessen this burden, a number of techniques have been developed to reduce the number of features in a dataset. Manifold learning is a popular approach to nonlinear dimensionality reduction. In this paper, we investigate Diffusion maps manifold learning method for web image auto-annotation task. Diffusion maps manifold learning method is used to reduce the dimension of some visual features. Extensive experiments and analysis on NUS-WIDE-LITE web image dataset with different visual features show how this manifold learning dimensionality reduction method can be applied effectively to image annotation.
