description: This study examined the foreign language (FL) reading anxiety level of learners of Chinese as a FL (n = 76) in the United States. Data from an FL reading anxiety survey, a background information survey and a face-to-face interview indicated that there was no significant difference in reading anxiety level among four course levels. In general, Chinese L2 learners experienced a medium level of reading anxiety. 100- and 400-level students experienced higher levels of reading anxiety compared to 200- and 300-level students. A regression model with background variables such as years of learning Chinese, heritage learner status, the number of foreign languages learned, and time spent in China significantly predicted learners’ reading anxiety levels and explained 15% of the variance in their reading anxiety. Worries relating to comprehension, unfamiliar topics, unknown pronunciation, and feeling uncomfortable reading aloud were identified as major sources of FL reading anxiety.

description: In this paper, we develop an alternating direction method of multipliers (ADMM) for deep neural networks training with sigmoid-type activation functions (called \textit{sigmoid-ADMM pair}), mainly motivated by the gradient-free nature of ADMM in avoiding the saturation of sigmoid-type activations and the advantages of deep neural networks with sigmoid-type activations (called deep sigmoid nets) over their rectified linear unit (ReLU) counterparts (called deep ReLU nets) in terms of approximation. In particular, we prove that the approximation capability of deep sigmoid nets is not worse than that of deep ReLU nets by showing that ReLU activation function can be well approximated by deep sigmoid nets with two hidden layers and finitely many free parameters but not vice-verse. We also establish the global convergence of the proposed ADMM for the nonlinearly constrained formulation of the deep sigmoid nets training from arbitrary initial points to a Karush-Kuhn-Tucker (KKT) point at a rate of order ${\cal O}(1/k)$. Besides sigmoid activation, such a convergence theorem holds for a general class of smooth activations. Compared with the widely used stochastic gradient descent (SGD) algorithm for the deep ReLU nets training (called ReLU-SGD pair), the proposed sigmoid-ADMM pair is practically stable with respect to the algorithmic hyperparameters including the learning rate, initial schemes and the pro-processing of the input data. Moreover, we find that to approximate and learn simple but important functions the proposed sigmoid-ADMM pair numerically outperforms the ReLU-SGD pair.

description: In these lectures, given in '96 summer schools in Beg-Rohu (France) and Budapest, I discuss the fundamental principles of thermodynamic and dynamic Monte Carlo methods in a simple light-weight fashion. The keywords are MARKOV CHAINS, SAMPLING, DETAILED BALANCE, A PRIORI PROBABILITIES, REJECTIONS, ERGODICITY, "FASTER THAN THE CLOCK ALGORITHMS". The emphasis is on ORIENTATION, which is difficult to obtain (all the mathematics being simple). A firm sense of orientation helps to avoid getting lost, especially if you want to leave safe trodden-out paths established by common usage. Even though I remain quite basic (and, I hope, readable), I make every effort to drive home the essential messages, which are easily explained: the crystal-clearness of detail balance, the main problem with Markov chains, the great algorithmic freedom, both in thermodynamic and dynamic Monte Carlo, and the fundamental differences between the two problems.

description: Direct electronic structure measurements of a variety of the colossal magnetoresistive oxides show the presence of a pseudogap at the Fermi energy E_F which drastically suppresses the electron spectral function at E_F. The pseudogap is a strong function of the layer number of the samples (sample dimensionality) and is strongly temperature dependent, with the changes beginning at the ferromagnetic transition temperature T_c. These trends are consistent with the major transport trends of the CMR oxides, implying a direct relationship between the pseudogap and transport, including the "colossal" conductivity changes which occur across T_c. The k-dependence of the temperature-dependent effects indicate that the pseudogap observed in these compounds is not due to the extrinsic effects proposed by Joynt.

description: Pulse dipolar electron paramagnetic resonance (PD EPR) spectroscopy is a technique with the ability to measure dipole-dipole interactions between unpaired electrons. Through careful analysis, distances between specifically selected protein residues can be extracted, and with it, protein structures and changes can be observed. In this thesis, the utility of two methods of PD EPR, double electron electron resonance (DEER) and relaxation induced dipolar modulation enhancement (RIDME), are tested, and their advantages and disadvantages elucidated, alongside a direct and detailed comparison of the numerous analysis softwares available to process their respective data. After establishing the experimental methods, a foray into a young technique in the field is introduced. Many conformations within a protein sample are often invisible to spectroscopic measurement due to being sparsely populated. However, by applying high pressures to the proteins, we can reversibly shift populations of conformational equilibria and thereby make these states visible and ready for measurement. Within, the details of building and testing a high pressure system capable of working in combination with DEER spectroscopy are discussed, alongside two research projects centring two different and distinct protein samples that prove high pressure EPR to be an exciting and promising experimental technique.

description: Transient current spectroscopy is proposed and demonstrated in order to investigate the energy relaxation inside a quantum dot in the Coulomb blockade regime. We employ a fast pulse signal to excite an AlGaAs/GaAs quantum dot to an excited state, and analyze the non-equilibrium transient current as a function of the pulse length. The amplitude and time-constant of the transient current are sensitive to the ground and excited spin states. We find that the spin relaxation time is longer than, at least, a few microsecond.

description: Low-energy high-resolution neutrino-electron scattering experiments may play an important role in testing the gauge structure of the electroweak interaction. We propose the use of radioactive neutrino sources (e.g. $^{51}$Cr) in underground experiments such as BOREXINO, HELLAZ and LAMA. As an illustration, we display the sensitivity of these detectors in testing the possible existence of extra neutral gauge bosons, both in the framework of E_6 models and of models with left-right symmetry.

O pastoreio é um aspeto fundamental da gestão para a poupança de água e energia. Contudo, a quantidade e qualidade da forragem dependem muito das condições climáticas. Nas regiões atlânticas francesas, as pastagens fornecem alimento na primavera e, em menor quantidade, no outono. No entanto, a produção de pastagem reduz- se muito no verão. As alterações climáticas irão provavelmente aumentar as condições de secura no fim da primavera e no verão, aumentando a variabilidade da produção anual de pastagem. As árvores e arbustos podem assim ser uma fonte de forragem complementar nas explorações leiteiras.

description: Popular graph neural networks implement convolution operations on graphs based on polynomial spectral filters. In this paper, we propose a novel graph convolutional layer inspired by the auto-regressive moving average (ARMA) filter that, compared to polynomial ones, provides a more flexible frequency response, is more robust to noise, and better captures the global graph structure. We propose a graph neural network implementation of the ARMA filter with a recursive and distributed formulation, obtaining a convolutional layer that is efficient to train, localized in the node space, and can be transferred to new graphs at test time. We perform a spectral analysis to study the filtering effect of the proposed ARMA layer and report experiments on four downstream tasks: semi-supervised node classification, graph signal classification, graph classification, and graph regression. Results show that the proposed ARMA layer brings significant improvements over graph neural networks based on polynomial filters.

description: We study the critical two-dimensional Ising model with a defect line (altered bond strength along a line) in the continuum limit. By folding the system at the defect line, the problem is mapped to a special case of the critical Ashkin-Teller model, the continuum limit of which is the $Z_2$ orbifold of the free boson, with a boundary. Possible boundary states on the $Z_2$ orbifold theory are explored, and a special case is applied to the Ising defect problem. We find the complete spectrum of boundary operators, exact two-point correlation functions and the universal term in the free energy of the defect line for arbitrary strength of the defect. We also find a new universality class of defect lines. It is conjectured that we have found all the possible universality classes of defect lines in the Ising model. Relative stabilities among the defect universality classes are discussed.

description: Wearables mit integrierten inertialen Messeinheiten ermöglichen neue Sensoranwendungen, die über längere Zeiträume hinweg messen. Die Arbeitsergonomie ist ein besonderer Bereich, in dem Wearables und intelligente Sensorik die Gesundheit und das Wohlbefinden vieler Menschen verbessern können. Personen in Büroumgebungen sind aufgrund anhaltender Fehlhaltungen besonders anfällig für Muskel-Skelett-Erkrankungen. Haltungsbedingte Probleme sind dadurch inzwischen der dritthäufigste gemeldete Risikofaktor für die Gesundheit am Arbeitsplatz. Das Ziel dieser Arbeit ist es, die Anwendung von Edge-AI-Technologien für eine kontinuierliche Bewertung ergonomischer Risikofaktoren am Schreibtischarbeitsplatz zu untersuchen. Der erstellte Ansatz bewertet die ergonomische Risikosituation eines Nutzers auf Basis der Körperhaltung und der Arbeitsplatzbedingungen und leitet daraus Verbesserungsvorschläge ab. Relevante Bewegungen werden kontinuierlich von einem Sensornetzwerk mit Beschleunigungssensoren und Gyroskopen erfasst, die an einem tragbaren Brillenrahmen sowie an einer Armlehne eines Bürostuhls angebracht sind. Diese Arbeit schlägt ein neuartiges domänenspezifisches maschinelles Lernverfahren und Zustandsübergangsmodell für die langfristige Ableitung von Körperhaltungen durch die Klassifizierung und Aggregation von Ereignissen vor, die in den Sensorzeitreihen auftreten. Zusätzlich wird ein Manifold von Bewegungen erstellt, der Schlussfolgerungen und Empfehlungen für ergonomisch relevante Körperbewegungen ermöglicht. Schließlich demonstriert eine Software-Implementierung die Techniken erfolgreich in der Praxis.

description: It is argued that the QCD dipole picture allows to build an unified theoretical description -based on BFKL dynamics- of the total and diffractive nucleon structure functions. This description is in qualitative agreement with the present collection of data obtained by the H1 collaboration. More precise theoretical estimates, in particular the determination of the normalizations and proton transverse momentum behaviour of the diffractive components, are shown to be required in order to reach definite conclusions.

description: A indexação em catálogos on-line na percepção de usuários que são membros de grupos de pesquisa torna-se crucial em um ambiente de bibliotecas universitárias para que o catálogo de assunto, primeiro restrito aos limites físicos da biblioteca e contendo apenas registros bibliográficos de documentos encomendados em estantes , se torna virtual hoje em dia. No entanto, os usuários têm dificuldades quando fazem sua busca por assunto, pois as palavras que utilizam não coincidem com os termos utilizados pelo bibliotecário no momento da indexação. Consequentemente, a recuperação da informação torna-se silenciosa e com ruído. Esta edição do catálogo de assunto é muitas vezes o reflexo de uma possível deficiência do trabalho realizado pelos bibliotecários, uma vez que não estudam sobre os usuários, a fim de conhecer seus interesses e opiniões sobre o tratamento do conteúdo dos documentos. É também um reflexo da falta de uma política de indexação que orienta os passos da indexação. Com o objetivo de contribuir para o desenvolvimento de uma política de indexação nas bibliotecas universitárias sob a ótica dos usuários, a proposta desta pesquisa foi fazer um estudo do contexto sociocognitivo de usuários que fazem parte de grupos de pesquisa nas áreas de Biologia e Exata.

description: It is shown, with the example of the experimentally known Adler function, that there is no matching in the intermediate region between the two asymptotic regimes described by perturbative QCD (for the very short-distances) and by chiral perturbation theory (for the very long-distances). We then propose to consider an approximation of large-Nc QCD which consists in restricting the hadronic spectrum in the channels with J^P quantum numbers 0^-, 1^-, 0^+ and 1^+ to the lightest state and treating the rest of the narrow states as a perturbative QCD continuum; the onset of this continuum being fixed by consistency constraints from the operator product expansion. We show how to construct the low-energy effective Lagrangian which describes this approximation. The number of free parameters in the resulting effective Lagrangian can be reduced, in the chiral limit where the light quark masses are set to zero, to just one mass scale and one dimensionless constant to all orders in chiral perturbation theory. A comparison of the corresponding predictions, to O(p^4) in the chiral expansion, with the phenomenologically known couplings is also made.

description: The physics of the electronic excitation in semiconductors induced by sub-GeV dark matter (DM) have been extensively discussed in literature, under the framework of the standard plane wave (PW) and pseudopotential calculation scheme. In this paper, we investigate the implication of the all-electron (AE) reconstruction on estimation of the DM-induced electronic transition event rates. As a benchmark study, we first calculate the wavefunctions in silicon and germanium bulk crystals based on both the AE and pseudo (PS) schemes within the projector augmented wave (PAW) framework, and then make comparisons between the calculated excitation event rates obtained from these two approaches. It turns out that in process where large momentum transfer is kinetically allowed, the two calculated event rates can differ by a factor of a few. Such discrepancies are found to stem from the high-momentum components neglected in the PS scheme. It is thus implied that the correction from the AE wavefunction in the core region is necessary for an accurate estimate of the DM-induced transition event rate in semiconductors.
description: A missing factor $64^{-3/2}=1/512$ associated with the Fourier transformation is added to both the AE and PS event rates in this version. The ratio between the AE and PS event rates is not affected

description: The photoluminescence (PL) spectrum of a two-dimensional electron gas (2DEG) in the fractional quantum Hall regime is studied. The response of the 2DEG to an optically injected valence hole depends on the separation d between the electron and hole layers. At d smaller than the magnetic length lambda, the PL spectrum shows recombination of neutral (X) and charged (X-) excitons. At d>lambda, the hole binds one or two Laughlin quasielectrons (QE) of the 2DEG to form fractionally charged excitons (FCX), hQE or hQE2. Different FCX states have different optical properties, and their stability depends critically on the presence of QE's in the 2DEG. This explains discontinuities observed in the PL spectrum at such (Laughlin) filling factors as nu=1/3 or 2/3.

description: In the weak coupling BCS-approximation normal impurities do not influence superconducting T_{c} in significant manner in case of isotropic s-wave pairing. However, in case of d-wave pairing these are strongly pair-breaking. This fact is in rather strong contradiction with many experiments on disordered high-T_{c} superconductors assuming the d-wave nature of pairing in these systems. With the growth of electron attraction within the Cooper pair the system smoothly crosses over from BCS-pairs to compact Boson picture of superconductivity. As pairing strength grows and pairs become compact significant deviations from universal Abrikosov-Gorkov dependence of T_{c} on disorder appear in case of d-wave pairing with superconducting state becoming more stable than in the weak coupling case. As high-T_{c} superconductors are actually in the intermediate region with Cooper pairs size of the order of few interatomic lengths, these results can explain the relative stability of d-wave pairing under rather strong disordering.

Inf., Prater, l.05.1911, 1 Ơ (Wachtl) (ZSSM). Non-type. Ukraine: Kyiv, Bilychi, 15.06.2010, 3 ♀; 28.06.2010, 1 Ơ (M. Zaika) (SIZK).
D i s t r i b u t i o n. Palaearctic; Ukraine (Varga, 2015 b).
 Remark. This species was recorded by Kasparyan (1981) from the Kharkiv and Kherson Regions of Ukraine. No additional material was found, and the species was included in the Ukrainian catalog of Varga (2015 b) based only on literature data. The paper also included another species, Xorides rusticus (Desvignes, 1856), identified on the basis of a female (partially damaged) collected in Kyiv. After examining the type specimens of X. ephialtoides and X. rusticus, the first author found that the Ukrainian female of X. rusticus differs from both species in that the first metasomal tergite is elongate (more robust in X. ephialtoides), with well developed carinae (not developed in X. rusticus). Furthermore, the black coloration of the hind trochanter, trochantellus, and partially of the femur in combination with the well developed carina of the first tergite suggest that the Ukrainian specimen may represent an unknown female of X. ilignus Hilszczański, 2000, but we currently refrain from describing it until male and female are collected or reared from the same locality. Therefore, X. rusticus should be excluded from the Ukrainian list of the subfamily Xoridinae.

description: Calorimetric measurements of AC loss and hence interstrand contact resistance (ICR), were measured on three samples of Rutherford cable wound with Cu-stabilized jelly-roll type unplated Nb3Al strand. One of the cable types was furnished with a thin core of AISI 316L stainless steel and the other two were both uncored but insulated in different ways. The cables were subjected to a room-temperature-applied uniaxial pressure of 12 MPa that was maintained during the reaction heat treatment (RHT), then vacuum impregnated with CTD 101 epoxy, and repressurized to 100 MPa during AC-loss measurement. The measurements were performed at 4.2 K in a sinusoidal field of amplitude 400 mT at frequencies of 1 to 90 mHz (no DC-bias field) that was applied both perpendicular and parallel to the face of the cable (the face-on, FO, and edge-on, EO, directions, respectively). For the cored cable the FO-measured effective ICR (FO-ICR), was 5.27 . Those for the uncored cables were less than 0.08 . As shown previously for NbTi- and Nb3Sn-based Rutherford cables, the FO-ICR can be significantly increased by the insertion of a core, although in this case it is still below the range recommended for accelerator-magnet use. Post-measurement dissection of one of the cables showed that the impregnating resin had permeated between the strands and coated the core with a thin, insulating layer excepting for some sintered points of contact. In the uncored cables the strands were coated with resin except for the points of interstrand contact. It is suggested that in the latter case this tendency for partial coating leads to a processing-sensitive FO-ICR.

description: The importance of general relativity to the induced electric field exterior to pulsars has been investigated by assuming aligned vacuum and non-vacuum magnetosphere models. For this purpose the stationary and axisymmetric vector potential in Schwarzschild geometry has been considered and the corresponding expressions for the induced electric field due to the rotation of the magnetic dipole have been derived for both vacuum and non-vacuum conditions. Due to the change in the magnetic dipole field in curved spacetime the induced electric field also changes its magnitude and direction and increases significantly near the surface of the star. As a consequence the surface charge density, the acceleration of charged particles in vacuum magnetospheres and the space charge density in non-vacuum magnetosphere greatly increase near the surface of the star. The results provide the most general feature of the important role played by gravitation and could have several potentially important implications for the production of high-energy radiation from pulsars.

description: Various applications in different fields, such as gene expression analysis or computer vision, suffer from data sets with high-dimensional low-sample-size (HDLSS), which has posed significant challenges for standard statistical and modern machine learning methods. In this paper, we propose a novel linear binary classifier, denoted by population-guided large margin classifier (PGLMC), which is applicable to any sorts of data, including HDLSS. PGLMC is conceived with a projecting direction w given by the comprehensive consideration of local structural information of the hyperplane and the statistics of the training samples. Our proposed model has several advantages compared to those widely used approaches. First, it is not sensitive to the intercept term b. Second, it operates well with imbalanced data. Third, it is relatively simple to be implemented based on Quadratic Programming. Fourth, it is robust to the model specification for various real applications. The theoretical properties of PGLMC are proven. We conduct a series of evaluations on two simulated and six real-world benchmark data sets, including DNA classification, digit recognition, medical image analysis, and face recognition. PGLMC outperforms the state-of-the-art classification methods in most cases, or at least obtains comparable results.

description: A generalization to any dimension of the fermion field transformation which allows to derive the solution of the massless Schwinger model in the path integral framework is identified. New arguments based on this transformation for a Nambu-Jona-Lasinio (NJL) like model as the low energy limit of a gauge theory in dimension greater than two are presented. Our result supports the spontaneous chiral symmetry breaking picture conjectured by Nambu many years ago and the link between QCD, NJL and chiral models.

description: A remarkable new genus of tribe Opsiini (Deltocephalinae), Yinformibus gen. nov. including Yinformibus menglaensis sp. nov. is described from Yunnan of China. The new genus is placed in the tribe Opsiini based on male adults having a pair of aedeagal shafts, each with its own gonopore. Partial 28S rDNA and Histone H3 sequences are provided for the new species, and a phylogenetic analysis based on these markers for Deltocephalinae retrieved from GenBank suggests Opsiini is monophyletic and supports the placement of Yinformibus gen. nov. in Opsiini. The molecular results placed the new genus in a clade comprising Hishimonus Ishihara, Opsius Fieber, and an undescribed genus from Zambia. Additionally, we also analysed the relationships of Yinformibus gen. nov. with other genera based on morphology. http://www.zoobank.org/urn:lsid:zoobank.org:pub:85C23AC3-8B19-4F29-9F55-BFC392242B51

description: A generalised integer S Ising spin glass model is analysed using the replica formalism. The bilinear couplings are assumed to have a Gaussian distribution with ferromagnetic mean = Jo. Incorporation of a quadrupolar interaction term and a chemical potential leads to a richer phase diagram with transitions of first and second order. The first order transition may be interpreted as a phase separation, and contrary to what has been argued previously, it persists in the presence of disorder. Finally, the stability of the replica symmetric solution with respect to fluctuations in replica space is analysed, and the transition lines are obtained both analytically and numerically.

description: Dementia represents a key impending global health challenge. The aim of this systematic review was to evaluate the current evidence on nutritional interventions for the prevention of dementia in developing economies in East-Asia. Four comprehensive databases were searched from inception until January 2020: MEDLINE, Embase, PsycInfo, and Scopus. The search was restricted to randomized controlled trials [RCTs] in adult humans, assessing the effect of nutritional interventions on global and domain specific cognitive performance and dementia risk. Meta-analysis of data was conducted for each domain and sub-categorized according to the type of nutritional intervention. Twenty-four RCTs were included, of which, fifteen studies showed significant beneficial effects on cognition. Eighteen studies were included in the meta-analysis. Significant beneficial effects were found for essential fatty acids (EPA/DHA) and micronutrient supplementation on specific cognitive domains including attention and orientation, perception, verbal functions and language skills. The effect size of the interventions appeared to be greater in older subjects with cognitive impairment. Supplementation with B-vitamins and essential fatty acids may represent promising strategies to minimize age-related cognitive decline in Asian populations. Large, high-quality, long-term trials are needed to confirm these findings.

description: We investigate, via three-dimensional atomistic computer simulations, phase separation in an alloy under external load. A regular two-dimensional array of cylindrical precipitates, forming a mesoscopic precipitate lattice, evolves in the case of applied tensile stress by the movement of mesoscopic lattice defects. A striking similarity to ordinary crystals is found in the movement of "meso-dislocations", but new mechanisms are also observed. Point defects such as "meso-vacancies" or "meso-interstitials" are created or annihilated locally by merging and splitting of precipitates. When the system is subjected to compressive stress, we observe stacking faults in the mesoscopic one-dimensional array of plate-like precipitates.

Decaying Dark Matter in Halos of Primordial Black Holes

description: We investigate photon signatures of general decaying dark-matter particles in halos of primordial black holes. We derive the halo-profile density and the total decay rate for these combined dark-matter scenarios. For the case of axion-like particles of masses below $\mathcal{O}( 1 )\,$keV, we find strong bounds on the decay constant which are several orders of magnitude stronger than the strongest existing bounds, for all halo masses above $\mathcal{O}( 10^{-5} )$ solar masses. Using future X-ray measurements, it will be possible to push these bounds on such combined dark-matter scenarios even further.

description: The Hubbard model for electrons with orbital degeneracy is shown to have an underlying SU_d(4) symmetry of spin-orbital double. A hidden charge SU_c(4) symmetry is exposed and an extended Lieb-Mattis transformation which maps these two symmetries into each other is given. On the basis of elementary degenerate perturbative theory, it is shown that the system with strong repulsive coupling is equivalent to a SO(6) Heisenberg magnet at half-filling and a SU(4) one at quarter-filling. The band is half-filled at all temperature for $μ=3U/2$. The features of ground state and low-lying excitations in one dimension are indicated according to exact solutions. Various possibilities of symmetry breaking are also given.
