description: I simulate the evolution of a stellar system hosting two stellar populations whose initial set up is defined according to the two main scenarios proposed for the origin of multiple populations in Galactic globular clusters: (i) formation of a second generation from a cooling flow of pristine+polluted gas and (ii) accretion of polluted gas onto the proto-stellar disks of a fraction of low-mass stars. For this purpose, Monte Carlo simulations containing from $10^{5}$ up to $3\cdot 10^{6}$ particles have been run including the effect of stellar evolution, binary interactions, external tidal field and a detailed modelling of the proto-stellar disk structure. The early accretion of gas onto proto-stellar disks is unable to produce discrete populations and to alter the chemical composition of a significant ($>10\%$) fraction of stars unless a disk lifetime larger ($t_{disk}\sim20~Myr$) than that predicted by models is assumed. Moreover, in this scenario the mixing timescale of the two populations is too short to reproduce the observed segregation of the chemically enriched population. On the other hand, simulations run within the cooling flow scenario can evolve after a Hubble time into stellar systems with a first-to-second population mass ratio similar to that observed in globular clusters, provided that an initial filling-factor $r_{h}/r_{J}>0.15$ is adopted. However, in the weak tidal field regime a radial segregation of the second population stronger than what observed in Milky Way globular clusters at large Galactocentric distances is predicted. This discrepancy disappears in simulations following eccentric orbits in a realistic axisymmetric potential.

description: Целью статьи является оценка влияния налогового бремени на доходы предприятия. Предлагаемая экономико-математическая модель механизма взаимодействия предприятия и государства позволяет выявить целесообразность создания и продолжения функционирования предприятия с позиций собственника, который оценивает достаточность дохода от деятельности предприятия. Государство также заинтересовано в создании и функционировании предприятия, т.к. оно не только приносит доход в виде налоговых отчислений, но и обеспечивает занятость населения. Поэтому государство стремится создать необходимые условия для деятельности предприятия. При этом учитывается масса факторов, которые могут обеспечивать предприятию конкурентные преимущества, способствуя тем самым увеличению дохода собственника. Но эти же факторы государство использует для налогообложения, т.к. считает, что собственник должен поделиться своими доходами за обладание теми преимуществами, которые ему предоставлены. Статья адресована, прежде всего, лицам, разрабатывающим налоговую систему для оценки последствий принятия тех или иных решений в этой области. Кроме того, статья может заинтересовать собственников предприятий, инвесторов, экономистов, а также представителей коммерческих банков.

description: It is shown why the discriminant of a maximal order within a cyclic division algebra must be minimized in order to get the densest possible matrix lattices with a prescribed nonvanishing minimum determinant. Using results from class field theory a lower bound to the minimum discriminant of a maximal order with a given center and index (= the number of Tx/Rx antennas) is derived. Also numerous examples of division algebras achieving our bound are given. E.g. we construct a matrix lattice with QAM coefficients that has 2.5 times as many codewords as the celebrated Golden code of the same minimum determinant. We describe a general algorithm due to Ivanyos and Ronyai for finding maximal orders within a cyclic division algebra and discuss our enhancements to this algorithm. We also consider general methods for finding cyclic division algebras of a prescribed index achieving our lower bound.

description: Working over an arbitrary field F of characteristic not 2, we consider linear algebraic groups over F. We view these as functors, represented by finitely generated F-Hopf algebras, from the category of commutative, associative, F-algebras Alg_F, to the category of groups. Classical examples of these groups, such as the special linear group SL_n are split, however there are also linear algebraic groups arising from central simple F-algebras which are non-split. For example, associated to a non-split central simple F-algebra A of degree n is a non-split special linear group SL(A). It is well known that central simple algebras are twisted forms of matrix algebras. This means that over the separable closure of F, denoted F_sep, we have A⊗_F F_sep ∼= M_n(F_sep) and that there is a twisted Gal(F_sep/F)-action on M_n(F_sep) whose fixed points are A. We show that a similar method of twisted Galois descent can be used to obtain all non-split semisimple linear algebraic groups associated to central simple algebras as fixed points within their split counterparts. In particular, these techniques can be used to construct the spin and half-spin groups Spin(A, τ ) and HSpin(A, τ ) associated to a central simple F-algebra of degree 4n with orthogonal involution. Furthermore, we develop a theory of twisted Galois descent for Hopf algebras and show how the fixed points obtained this way are the representing Hopf algebras of our non-split groups. Returning to the view of group schemes as functors, we discuss how the group schemes we consider are sheaves on the étale site of Alg_F whose stalks are Chevalley groups over local, strictly Henselian F-algebras. This allows us to use the generators and relations presentation of Chevalley groups to explicitly describe group scheme morphisms. After showing how the Kronecker tensor product of matrices induces maps between simply connected groups, we give an explicit description of these maps in terms of Chevalley generators. This allows us to compute the kernel of these new maps composed with standard isogenies and thereby construct new tensor product maps between non-simply connected split groups. These new maps are Gal(F_sep/F)-morphisms and so we apply our techniques of twisted Galois descent to also obtain new tensor product morphisms between non-split groups schemes. Finally, we use one of our new split tensor product maps to compute the degree three cohomological invariants of HSpin_4n for all n.

On the relation between Lya absorbers and local galaxy filaments

description: The intergalactic medium (IGM) is believed to contain the majority of baryons in the universe and to trace the same dark matter structure as galaxies, forming filaments and sheets. Lya absorbers, which sample the neutral component of the IGM, have been extensively studied at low and high redshift, but the exact relation between Lya absorption, galaxies and the large-scale structure is observationally not well-constrained. In this study, we aim at characterising the relation between Lya absorbers and nearby overdense cosmological structures (galaxy filaments) at recession velocities Delta v \leq 6700 km/s by using archival observational data from various instruments. We analyse 587 intervening Lya absorbers in the spectra of 302 extragalactic background sources obtained with the COS installed on the HST. We combine the absorption-line information with galaxy data of five local galaxy filaments originally mapped by Courtois et al. (2013). Along the 91 sightlines that pass close to a filament, we identify 215 (227) Lya absorption systems (components). Among these, 74 Lya systems are aligned in position and velocity with the galaxy filaments, indicating that these absorbers and the galaxies trace the same large-scale structure. The filament-aligned Lya absorbers have a ~90 percent higher rate of incidence (dN/dz=189 for log N HI \geq 13.2) and a mildly shallower slope (-beta = -1.47) of the column density distribution function than the general Lya population at z=0, reflecting the filaments' matter overdensity. The strongest Lya absorbers are preferentially found near galaxies or close to the axis of a filament, although there is substantial scatter in this relation. Our sample of absorbers clusters more strongly around filament axes than a randomly distributed sample would do (as confirmed by a KS test), but the clustering signal is less pronounced than for the galaxies in the filaments.

description: We show that an arbitrary basis of a multipartite quantum state space consisting of $K$ distant parties such that the $k$th party has local dimension $d_k$ always contains at least $N=\sum_{k=1}^K (d_k-1)+1$ members that are unambiguously distinguishable using local operations and classical communication (LOCC). We further show this lower bound is optimal by analytically constructing a special product basis having only $N$ members unambiguously distinguishable by LOCC. Interestingly, such a special product basis not only gives a stronger form of the weird phenomenon ``nonlocality without entanglement", but also implies the existence of locally distinguishable entangled basis.

description: The literature on the effects of video game training are mixed and some methodological concerns have appeared recently. To overcome previous limitations, we conducted a study with young adults (19 to 35 years of age) distributed into an experimental group and an active control group. The experimental group was trained with adaptive video games from Lumosity and the active control group with a simulation-strategy game (Electronic Arts Inc.) the same number of sessions in identical conditions for 3-4 weeks, 30-35 min per day. Transfer effects on selective attention, distraction, alertness, interference and visuo-spatial working memory were assessed using the Crossmodal Oddball Task, the Classical Stroop Color-Word Task and the Corsi Blocks Test. Moreover, placebo effects were controlled measuring motivation, engagement and expectations at several points of the intervention. Results showed improved performance across training sessions. Furthermore, video games cognitive benefits were obtained in visuo-spatial working memory, selective attention and distraction in both groups but no effects were observed in cognitive control and alertness.

description: We study a resurgence structure of a quantum field theory with a phase transition to uncover relations between resurgence and phase transitions. In particular, we focus on three-dimensional $\mathcal{N}=4$ supersymmetric quantum electrodynamics (SQED) with multiple hypermultiplets, where a second-order quantum phase transition has been recently proposed in the large-flavor limit. We provide interpretations of the phase transition from the viewpoints of Lefschetz thimbles and resurgence. For this purpose, we study the Lefschetz thimble structure and properties of the large-flavor expansion for the partition function obtained by the supersymmetric localization. We show that the second-order phase transition is understood as a phenomenon where a Stokes and anti-Stokes phenomenon occurs simultaneously. The order of the phase transition is determined by how saddles collide at the critical point. In addition, the phase transition accompanies an infinite number of Stokes phenomena due to the supersymmetry. These features are appropriately mapped to the Borel plane structures as the resurgence theory expects. Given the lessons from the SQED, we provide a more general discussion on the relationship between the resurgence and phase transitions. In particular, we show how the information on the phase transition is decoded from the Borel resummation technique.

description: Previous meta-analytic and intervention studies with older adults showed that computerized cognitive training enhance aspects of cognition that decline with aging. Most of these studies compared results of trained and non-contact control groups. In this ongoing RCT participate 75 older adults randomly assigned to the experimental group, which received 16 1-hr training sessions in the presence of the trainer over 10-12 weeks with video games selected from Lumosity or to the active-control group, which was trained with The Sims. Groups were similar at baseline on demographics, global cognition, and depression status. Participants were tested before and after the intervention on a series of attention (Cross-modal Oddball, Stroop, and Negative Priming) and working memory (Corsi Blocks and N-back) tasks. Results will clarify whether the intervention improves attention and working memory functions in older adults.

description: Problem-Based Learning (PBL) is a popular approach to instruction that supports students to get hands-on training by solving problems. Question Pool websites (QPs) such as LeetCode, Code Chef, and Math Playground help PBL by supplying authentic, diverse, and contextualized questions to students. Nonetheless, empirical findings suggest that 40% to 80% of students registered in QPs drop out in less than two months. This research is the first attempt to understand and predict student dropouts from QPs via exploiting students' engagement moods. Adopting a data-driven approach, we identify five different engagement moods for QP students, which are namely challenge-seeker, subject-seeker, interest-seeker, joy-seeker, and non-seeker. We find that students have collective preferences for answering questions in each engagement mood, and deviation from those preferences increases their probability of dropping out significantly. Last but not least, this paper contributes by introducing a new hybrid machine learning model (we call Dropout-Plus) for predicting student dropouts in QPs. The test results on a popular QP in China, with nearly 10K students, show that Dropout-Plus can exceed the rival algorithms' dropout prediction performance in terms of accuracy, F1-measure, and AUC. We wrap up our work by giving some design suggestions to QP managers and online learning professionals to reduce their student dropouts.

description: Data from the LIGO Livingston interferometer and the ALLEGRO resonant bar detector, taken during LIGO's fourth science run, were examined for cross-correlations indicative of a stochastic gravitational-wave background in the frequency range 850-950 Hz, with most of the sensitivity arising between 905 Hz and 925 Hz. ALLEGRO was operated in three different orientations during the experiment to modulate the relative sign of gravitational-wave and environmental correlations. No statistically significant correlations were seen in any of the orientations, and the results were used to set a Bayesian 90% confidence level upper limit of Omega_gw(f) <= 1.02, which corresponds to a gravitational wave strain at 915 Hz of 1.5e-23/rHz. In the traditional units of h_100^2 Omega_gw(f), this is a limit of 0.53, two orders of magnitude better than the previous direct limit at these frequencies. The method was also validated with successful extraction of simulated signals injected in hardware and software.

description: Andy Hamilton’s Aesthetics and Music is an unusual concoction: one part history of the aesthetics of music, one part review of recent work in the Analytic philosophy of music, and one part original contribution to musical aesthetics. Published as part of Continuums’s new series of introductory texts on art and aesthetics, Hamilton’s book is more than a student text and less than a specialist’s essay. Three historical chapters-which quickly survey the musical aesthetics of ancient Greece, Kant and the nineteenth century, and Adorno and modernism- alternate with philosophical chapters that treat some recalcitrant problems in a more sustained manner.Hamilton seeks to overturn the kind of thinking which dismisses the genetic role of improvisation in the overall aesthetic effect of the music. In other words, he confronts the claim that improvisation is essentially musically extrinsic- that the only thing that matters is the musical result, regardless of whether the music is or is not improvised.

Classroom language activities in a Chinese as a foreign language class of young beginners
Creators: name: Huang, Jingzi
Publisher: name: University of British Columbia
Year: 2011

description: The present study is a qualitative one concerning classroom language activities in a foreign language classroom. Studies in language education have in recent years focused on the integration of language and content as one possible way to benefit the students both linguistically and cognitively. Among the research efforts on a content-based approach., Mohan's (1986) Knowledge Framework (KF) provides a systematic way to organize classroom activities combining language and content. However, it is believed by some people that a content-based approach can only apply to learners above the beginning level and that beginners' language classes should be organized solely around language categories. The present study attempts to investigate the feasibility of adopting a content-based approach in a regular Chinese as a foreign language class for young beginners by examining the on-going process of classroom language activities organized around Mohan's KF. The empirical evidence provided by the study indicates that it is feasible to apply a content-based approach in teaching a foreign language to young beginners in normal classroom situations: (1) By engaging in activities organized around the KF, the students in the study used Chinese (though in combination with English) in their interactions, seemed to understand the topics or content of the activities they were engaged in, were involved in certain thinking processes, and represented knowledge structures with graphics; (2) The study shows that classroom activities on a chosen topic can lead to the systematic use of features of language by foreign language students at the beginning level, in the ways indicated by the KF analysis of the topic. In providing an analytical description of the on-going process of classroom language activities around the KF, how the KF was adopted, and how the teacher and the students worked with the KF, the study further supports the argument empirically that the principles underlying the KF apply not only to learners above the beginning level, but also to learners who are beginners; not only to second language learners, but also to foreign language learners. On the basis of the study, suggestions on program improvement and recommendations for further research are considered.

description: Correct swap action can be realized via the control of the anisotropic Heisenberg interaction in solid-state quantum systems. The conditions of performing a swap are derived by the dynamics of arbitrary bipartite pure state. It is found that swap errors can be eliminated in the presence of symmetric anisotropy. In realistic quantum computers with unavoidable fluctuations, the gate fidelity of swap action is estimated. The scheme of quantum computation via the anisotropic Heisenberg interaction is implemented in a one dimensional quantum dots. The slanting and static magnetic field can be used to adjust the anisotropy.

description: The explicit procedures are described for reconstruction of the full set of helicity amplitudes in proton-proton and proton-antiproton elastic scattering. The procedures are based on the derivative relations for the helicity amplitudes in s-channel, on the explicit parametrization of the leading spin non flip amplitudes and crossing - symmetry relations. Asymptotic theorems are used for definition of free parameters in derivative relations. We also study the Odderon influence on the helicity amplitude reconstruction. Reconstruction procedures are valid at extremely wide energy domain and broad range of momentum transfer. These procedures might be useful in studying the spin phenomena in proton-proton and proton-antiproton elastic scattering.

description: We explore the significance of laser-induced correlation effects for high-order harmonic generation (HHG) in a linear chain model of a generic band gap material for both single-IR-pulse and VUV-pump--IR-probe HHG schemes. We examine various pump-pulse excitations, and catagorize signatures of laser-induced correlation effects into two classes related to edge-state and bulk-like effects. The relative importance of the edge-state effects decrease with increasing system-size, while the bulk-like effects remain. We identify regimes where these effects may alter the harmonic yield by an order of magnitude, but also regions where they may be neglected. We characterize the underlying laser-induced dynamics of the correlational mechanisms, using both an electronic population-description in a static field-free basis, and comparing to a bandstructure-picture with laser-induced time-dependent energy shifts. From this we provide a guideline on when to account for laser-induced electron correlations and give an estimate of the time-scale in which the laser-induced electron-electron interactions can cause correlational changes in the harmonic spectra. We find this timescale to be a few tens of femtoseconds.

This randomized controlled trial (RCT, registered at Clinicaltrials. gov: NCT02796508), was designed to overcome some limitations of previous studies by incorporating an active-control group and the assessment of training expectations. The main objectives were to evaluate the behavioral and electrophysiological effects of training older adults with non-action video games on attention and spatial working memory, two abilities that decline with age; and to explore whether motivation or expectations account for training-related improvements. In the study participated 75 cognitively healthy older adults assigned to the experimental group, who received 16 1-hour training sessions with 10 cognitive non-action video games from Lumosity, or to the active-control group, trained with The Sims and SimCity (a strategy game). The design is a RCT with two groups, pre-test, post-test, and 6-month follow-up repeated measures design. Before and after the 16 training sessions, participants completed several experimental working memory and attentional tasks. The follow-up assessment will show whether the benefits persist beyond training. Preliminary behavioral results suggest that participants improved on the training games. Both groups showed transfer to untrained Corsi blocks and N-back WM tasks but larger in the active-control group who outperformed the experimental group on cross-modal Oddball and Stroop attentional tasks. Groups did not differ in perceived improvements. The question is whether the same pattern of results will be obtained in young adults.

description: Using the light-cone QCD dipole formalism we investigate manifestations of color transparency (CT) and coherence length (CL) effects in electroproduction of longitudinally (L) and transversally (T) polarized vector mesons. Motivated by forthcoming data from the HERMES experiment we predict both the A and Q^2 dependence of the L/T- ratios, for rho^0 mesons produced coherently and incoherently off nuclei. For an incoherent reaction the CT and CL effects add up and result in a monotonic A dependence of the L/T-ratio at different values of Q^2. On the contrary, for a coherent process the contraction of the CL with Q^2 causes an effect opposite to that of CT and we expect quite a nontrivial A dependence, especially at Q^2 >> m_V^2.

description: This is the fifth book in an excellent series from Scarecrow Press entitled Europea: Ethnomusicologies and Modernities. The Mediterranean island of Corsica yields a particularly rich case study for this series, which seeks in part to investigate the trajectories of traditional musics in a “postnational” Europe. Caroline Bithell’s sophisticated and sensitive study of Corsican musical life since the late twentieth century tells a story about a culture continually renegotiating its relationship to modernity, to the rest of Europe, and to the world. Bithell draws on over a decade of fieldwork to produce a book of historical depth and ethnographic rigor. Her analyses of ever-loving musical practices offer insights into the contested site of “the traditional” not just in Corsica but all over the globe.

description: Основная цель исследования заключается в изучении перспектив повышения эффективности государственного финансового контроля за трансграничными операциями российских резидентов, в первую очередь, физических лиц, в условиях реализации международного многостороннего соглашения компетентных органов об автоматическом обмене финансовой информацией от 29 октября 2014 г. В статье рассматриваются основные подходы к понятию «эффективность налогового администрирования», предложенные российскими и зарубежными авторами, анализируются факторы, оказывающие на него влияние и способы повысить эффективность в условиях многократного увеличения объема данных, обрабатываемых налоговыми органами. Большое внимание уделено вопросу сотрудничества между налоговыми органами и налогоплательщиками, правового просвещения. Автор приходит к выводу, что в условиях международной налоговой прозрачности возникла необходимость в качественном изменении норм права в сфере финансового контроля за трансграничными операциями российских резидентов, что позволит, с одной стороны, сделать более эффективным налоговое администрирование и валютный контроль за счет оптимизации источников получения информации государственными органами, а также за счет развития риск-ориентированного подхода, и, с другой стороны, снизить избыточную процессуальную нагрузку на обе стороны финансового правоотношения.

description: Bipolare HGÜ Systeme in Multi-Level-Ausführung stellen ein attraktives Lösungskonzept zur Bewältigung einer Vielzahl von Herausforderungen im Kontext heutiger Energiesysteme dar. Da dies jedoch auf Kosten einer deutlich erhöhten Systemkomplexität geschieht, ist ein tiefgreifendes Verständnis des transienten Verhaltens sowie der dynamischen Charakteristik von enormer Wichtigkeit. Diese Doktorarbeit beinhaltet eine detaillierte Analyse von grundlegenden Zusammenhängen bezogen auf bipolare HGÜ Systeme in Multi-Level-Ausführung und stellt ein generisches Regelungs-, Bilanzierungs- und Schutzkonzept vor. Die generelle Leistungsfähigkeit des Konzepts wird durch elektro-magnetische Transientensimulationen nachgewiesen.

description: The Pierre Auger Observatory in Malargue, Argentina, is designed to study the origin of ultrahigh energy cosmic rays with energies above 10^18 eV. The energy calibration of the detector is based on a system of four air fluorescence detectors. To obtain reliable calorimetric information from the fluorescence stations, the atmospheric conditions at the experiment's site need to be monitored continuously during operation. One of the components of the observatory's atmospheric monitoring system is a set of four elastic backscatter lidar stations, one station at each of the fluorescence detector sites. This paper describes the design, current status, standard operation procedure, and performance of the lidar system of the Pierre Auger Observatory.

Unveiling the broadband spectral and temporal properties of PKS\,0903-57 during its brightest flare

description: We carried a detailed spectral and temporal study of blazar, \mbox{PKS\,0903-57} using the \emph{Fermi}-LAT and \emph{Swift}-XRT/UVOT observations, during its brightest flaring period MJD\,58931--58970. During this period, the maximum daily averaged $γ$-ray flux ($\rm F_{0.1-500\,GeV}$) of $\rm9.42\times10^{-6}\,ph\,cm^{-2}\,s^{-1}$ is observed on MJD\,58951.5, the highest $γ$-ray flux detected from \mbox{PKS\,0903-57} till now. Several high-energy (HE) photons ($>\,10$\,GeV) consistent with the source location at high probability (>\,99\%) are detected, and the $γ$-ray lightcurve in the active state shows multiple substructures with asymmetric profile. In order to understand the possible physical scenario responsible for the flux enhancement, we carried a detailed broadband spectral study of \mbox{PKS\,0903-57} by choosing different flux states from its active period. Neglecting the multi-band variability in each of the selected time intervals, we could reproduce their averaged broadband SEDs with a one-zone leptonic model whose parameters were derived with a $χ^2$-fit. We found that the broadband SED during different flux states can be reproduced by the synchrotron, synchrotron-self-Compton (SSC) and External-Compton (EC) processes. The seed photons for EC process from BLR or IR torus provide acceptable fits to the GeV spectrum in all the flux states; however, the detection of HE photons together with the equipartition condition suggest that the EC/IR process is a more likely scenario. Further, a detailed comparison between the fit parameters shows that the flux enhancement from quiescent-state to the flaring-state is mostly related to increase in the bulk Lorentz factor of the emission region and change in the break energy of the source spectrum.

description: The effective Heisenberg interaction of long distance is constructed in spin qubits connected to a bus of two strongly coupled chains. Universal quantum computation can be realized on the basis of the bus which always keeps frozen at the ground state. It is found that the effective interaction is primarily determined by the energy spectra of the bus. With the variation of the distance between two connecting nodes, the interaction alternately occurs between antiferromagnetic and ferromagnetic ones. The long range interaction can also be attained in coupled infinite chains. The quantum gate operations with the high precision are implemented in the condition of quantum fluctuations.
