description: Let $\mathbf{T}$ be a pair of commuting hyponormal operators satisfying the so-called quasitriangular property $$ \textrm{dim} \; \textrm{ker} \; (\mathbf{T}-\boldsymbolλ) \ge \textrm{dim} \; \textrm{ker} \; (\mathbf{T} - {\boldsymbolλ})^*), $$ for every $\boldsymbolλ$ in the Taylor spectrum $σ(\mathbf{T})$ of $\mathbf{T}$. We prove that the Weyl spectrum of $\mathbf{T}$, $ω(\mathbf{T})$, satisfies the identity $$ ω(\mathbf{T})=σ(\mathbf{T}) \setminus π_{00}(\mathbf{T}), $$ where $π_{00}(\mathbf{T})$ denotes the set of isolated eigenvalues of finite multiplicity. Our method of proof relies on a (strictly $2$-variable) fact about the topological boundary of the Taylor spectrum; as a result, our proof does not hold for $d$-tuples of commuting hyponormal operators with $d>2$.

description: Objectives: Test anxiety is well known among medical students. However, little is known about test anxiety produced by different components of exam individually. This study aimed to stratify varying levels of test anxiety provoked by each exam modality and to explore the students perceptions about confounding factors. Methods: A self-administered questionnaire was administered to medical students. The instrument contained four main themes; lifestyle, psychological and specific factors of information needs, learning styles, and perceived difficulty level of each assessment tool. Results: A highest test anxiety score of 5 was ranked for “not scheduling available time” and “insufficient exercise” by 28.8 and 28.3% students, respectively. For “irrational thoughts about exam” and “fear to fail”, a highest test anxiety score of 5 was scored by 28.8 and 25.7% students, respectively. The highest total anxiety score of 1255 was recorded for long case exam, followed by 975 for examiner-based objective structured clinical examination. Excessive course load and course not well covered by faculty were thought to be the main confounding factors. Conclusions: The examiner-based assessment modalities induced high test anxiety. Faculty is urged to cover core contents within stipulated time and to rigorously reform and update existing curricula to prepare relevant course material.
Homodyne Bell's inequalities for entangled mesoscopic superpositions

description: We present a scheme for demonstrating violation of Bell's inequalities using a spin-1/2 system entangled with a pair of classically distinguishable wave packets in a harmonic potential. In the optical domain, such wave packets can be represented by coherent states of a single light mode. The proposed scheme involves standard spin-1/2 projections and measurements of the position and the momentum of the harmonic oscillator system, which for a light mode can be realized by means of homodyne detection. We discuss effects of imperfections, including non-unit efficiency of the homodyne detector, and point out a close link between the visibility of interference and violation of Bell's inequalities in the described scheme.

First MHD Simulation of Collapse and Fragmentation of Magnetized Molecular Cloud Cores

description: This is the first paper about the fragmentation and mass outflow in the molecular cloud by using three-dimensional MHD nested-grid simulations. The binary star formation process is studied paying particular attention to the fragmentation of a rotating magnetized molecular cloud. We assume an isothermal rotating and magnetized cylindrical cloud in hydrostatic balance. Non-axisymmetric as well as axisymmetric perturbations are added to the initial state and the subsequent evolutions are studied. The evolution is characterized by three parameters: the amplitude of the non-axisymmetric perturbations, the rotation speed, and the magnetic field strength. As a result, it is found that non-axisymmetry hardly evolves in the early phase, but begins to grow after the gas contracts and forms a thin disk. Disk formation is strongly promoted by the rotation speed and the magnetic field strength. There are two types of fragmentation: fragmentation from a ring and that from a bar. Thin adiabatic cores fragment if a thickness is smaller than 1/4 of the radius. For the fragments to survive, they should be formed in a heavily elongated barred core or a flat round disk. In the models showing fragmentation, outflows from respective fragments are found as well as those driven by the rotating bar or the disk.

description: Biotehnološka i farmaceutska industrija predstavlja najbrže rastuću
 industriju današnjice s daljom tendencijom rasta. Ova industrija ulaže u istraživanja
 i razvoj više od svih ostalih industrija poput vojne, aero industrije i poslednjih decenija
 IT industrije. Zanemarivanje ove industrije na tržištu Srbije predstavlja sprečavanje
 velike razvojne šanse. Pre svega su značajna in vitro i in vivomedicinska istraživanja
 koja mogu biti inicirana stranim direktnim investicijama (SDI) ili razvojem domaćih
 istraživačkih kompanija i centara. Ovakvim razvojem se doprinosi višestruko, kako
 direktno na rast bruto društvenog proizvoda (BDP), tako i indirektno smanjenjem
 finansijskog pritiska na zdravstveni sistem, te dalji razvoj nauke, sprečavanje odlaska
 u inostranstvo naših stručnjaka dr. Društveni i politički uticaji su posredni
 (sekundarni) i zasnovani na prethodno nabrojanim (primarnim) ciljevima.
 Horizontalni i vertikalni transfer tehnologija učvršćuje i razvija istraživačku nišu, a
 samim tim i položaj naučno-obrazovnih institucija. Važno je privlačiti SDI u ovoj
 oblasti, a neophodan uslov je zakonodavno uređenje koje će „negovati inovaciju” (uz
 adekvatnu efikasnost, transparentnost i sprovođenje donetih zakona). Značajno je
 paralelno razvijati domaći sektor po modelu drugih zemalja poput Izraela.

description: We report on the first observation of stimulated Raman scattering from a Lambda-type three-level atom, where the stimulation is realized by the vacuum field of a high-finesse optical cavity. The scheme produces one intracavity photon by means of an adiabatic passage technique based on a counter-intuitive interaction sequence between pump laser and cavity field. This photon leaves the cavity through the less-reflecting mirror. The emission rate shows a characteristic dependence on the cavity and pump detuning, and the observed spectra have a sub-natural linewidth. The results are in excellent agreement with numerical simulations.

description: Discovering underlying low dimensional structure of a high-dimensional matrix is traditionally done through low rank matrix approximations in the form of a sum of rank-one matrices. In this article, we propose a new approach. We assume a high-dimensional matrix can be approximated by a sum of a small number of Kronecker products of matrices with potentially different configurations, named as a hybrid Kronecker outer Product Approximation (hKoPA). It provides an extremely flexible way of dimension reduction compared to the low-rank matrix approximation. Challenges arise in estimating a hKoPA when the configurations of component Kronecker products are different or unknown. We propose an estimation procedure when the set of configurations are given, and a joint configuration determination and component estimation procedure when the configurations are unknown. Specifically, a least squares backfitting algorithm is used when the configurations are given. When the configurations are unknown, an iterative greedy algorithm is developed. Both simulation and real image examples show that the proposed algorithms have promising performances. Some identifiability conditions are also provided. The hybrid Kronecker product approximation may have potentially wider applications in low dimensional representation of high-dimensional data. Supplementary materials for this article are available online.

description: Context. On September 2016 the first data from Gaia were released (DR1). The first release included photometry for over 10^9 sources in the very broad G system. Aims. To test the correspondence between G magnitudes in DR1 and the synthetic equivalents derived using spectral energy distributions from observed and model spectrophotometry. To correct the G passband curve and to measure the zero point in the Vega system. Methods. I have computed the synthetic G and Tycho-2 BV photometry for a sample of stars using the Next Generation Spectral Library (NGSL) and the Hubble Space Telescope (HST) CALSPEC spectroscopic standards. Results. I have found that the nominal G passband curve is too blue for the DR1 photometry, as shown by the presence of a color term in the comparison between observed and synthetic magnitudes. A correction to the passband applying a power law in lambda with an exponent of 0.783 eliminates the color term. The corrected passband has a Vega zero point of 0.070$\pm$0.004 magnitudes.

description: Why do so many Americans hold misperceptions? We examine two factors that contribute to the prevalence of these beliefs. First, presenting correct information should reduce misperceptions, especially if provided in a clear and compelling format. We therefore test the effect of graphical information, which may be especially effective in facilitating belief updating about changes in quantities over time. In some cases, though, people may reject information because it threatens their worldview or self-concept – a mechanism that can be revealed by affirming individuals’ self-worth, which could make them more willing to acknowledge uncomfortable facts. We test both mechanisms jointly. In three experiments, we find that providing information in graphical form reduces misperceptions. A third study shows that this effect is greater than for equivalent textual information. Our findings for self-affirmation are more equivocal. We find limited evidence that self-affirmation can help diminish misperceptions when no other information is provided, but it does not consistently increase willingness to accept corrective information as previous research in social psychology would suggest. These results suggest that misperceptions are caused by a lack of information as well as psychological threat, but that these factors may interact in ways that are not yet well understood.

description: The Guitar nebula is a spectacular example of an H-alpha bow shock nebula produced by the interaction of a neutron star with its environment. The radio pulsar B2224+65 is traveling at ~800--1600 km/s (for a distance of 1--2 kpc), placing it on the high-velocity tail of the pulsar velocity distribution. Here we report time evolution in the shape of the Guitar nebula, the first such observations for a bow shock nebula, as seen in H-alpha imaging with the Hubble Space Telescope. The morphology of the nebula provides no evidence for anisotropy in the pulsar wind, nor for fluctuations in the pulsar wind luminosity. The nebula shows morphological changes over two epochs spaced by seven years that imply the existence of significant gradients and inhomogeneities in the ambient interstellar medium. These observations offer astrophysically unique, in situ probes of length scales between 5E-4 pc and 0.012 pc. Model fitting suggests that the nebula axis -- and thus the three-dimensional velocity vector -- lies within 20 degrees of the plane of the sky, and also jointly constrains the distance to the neutron star and the ambient density.

description: The problem of learning structural equation models (SEMs) from data is a fundamental problem in causal inference. We develop a new algorithm --- which is computationally and statistically efficient and works in the high-dimensional regime --- for learning linear SEMs from purely observational data with arbitrary noise distribution. We consider three aspects of the problem: identifiability, computational efficiency, and statistical efficiency. We show that when data is generated from a linear SEM over $p$ nodes and maximum degree $d$, our algorithm recovers the directed acyclic graph (DAG) structure of the SEM under an identifiability condition that is more general than those considered in the literature, and without faithfulness assumptions. In the population setting, our algorithm recovers the DAG structure in $\mathcal{O}(p(d^2 + \log p))$ operations. In the finite sample setting, if the estimated precision matrix is sparse, our algorithm has a smoothed complexity of $\widetilde{\mathcal{O}}(p^3 + pd^7)$, while if the estimated precision matrix is dense, our algorithm has a smoothed complexity of $\widetilde{\mathcal{O}}(p^5)$. For sub-Gaussian noise, we show that our algorithm has a sample complexity of $\mathcal{O}(\frac{d^8}{\varepsilon^2} \log (\frac{p}{\sqrtδ}))$ to achieve $\varepsilon$ element-wise additive error with respect to the true autoregression matrix with probability at most $1 - δ$, while for noise with bounded $(4m)$-th moment, with $m$ being a positive integer, our algorithm has a sample complexity of $\mathcal{O}(\frac{d^8}{\varepsilon^2} (\frac{p^2}δ)^{1/m})$.
Perspectives in measuring the PPN parameters beta and gamma in the Earth's gravitational fields with the CHAMP/GRACE models

Year: 2006

description: The current bounds on the PPN parameters gamma and beta are of the order of 10^-4-10^-5. Various missions aimed at improving such limits by several orders of magnitude have more or less recently been proposed like LATOR, ASTROD, BepiColombo and GAIA. They involve the use of various spacecraft, to be launched along interplanetary trajectories, for measuring the effects of the solar gravity on the propagation of electromagnetic waves. In this paper we investigate what is needed to measure the combination nu=(2+2gamma-beta)/3 of the post-Newtonian gravitoelectric Einstein perigee precession of a test particle to an accuracy of about 10^-5 with a pair of drag-free spacecraft in the Earth's gravitational field. It turns out that the latest gravity models from the dedicated CHAMP and GRACE missions would allow to reduce the systematic error of gravitational origin just to this demanding level of accuracy. In regard to the non-gravitational errors, the spectral noise density of the drag-free sensors required to reach such level of accuracy would amounts to 10^-8-10^-9 cm s^-2 Hz^-1/2 over very low frequencies. Although not yet obtainable with the present technologies, such level of compensation is much less demanding than those required for, e.g., LISA. As a by-product, an independent measurement of the post-Newtonian gravitomagnetic Lense-Thirring effect with a 0.9% accuracy would be possible as well. The forthcoming Earth gravity models from CHAMP and GRACE will further reduce the systematic gravitational errors in both of such tests.

description: We present real-time inchworm quantum Monte Carlo results for single-site dynamical mean field theory on an infinite coordination number Bethe lattice. Our numerically exact results are obtained on the L-shaped Keldysh contour and, being evaluated in real-time, avoid the analytic continuation issues typically encountered in Monte Carlo calculations. Our results show that inchworm Monte Carlo methods have now reached a state where they can be used as dynamical mean field impurity solvers and the dynamical sign problem can be overcome. As non-equilibrium problems can be simulated at the same cost, we envisage the main use of these methods as dynamical mean field solvers for time-dependent problems far from equilibrium.

description: We match analytic results to numerical calculations to provide a detailed picture of the metal-insulator and topological transitions found in density functional plus cluster dynamical mean-field calculations of pyrochlore iridates. We discuss the transition from Weyl metal to Weyl semimetal regimes, and then analyse in detail the properties of the Weyl semimetal phase and its evolution into the topologically trivial insulator. The energy scales in the Weyl semimetal phase are found to be very small, as are the anisotropy parameters. The electronic structure can to a good approximation be described as `Weyl rings' and one of the two branches that contributes to the Weyl bands is essentially flat, leading to enhanced susceptibilities.

First signatures of strong differential rotation in A-type stars

description: We reanalyzed high quality spectra of 158 stars of spectral types A0--F1 and $v \sin{i}$ between 60 and 150 km s$^{-1}$. Using a Least Squares Deconvolution technique we extracted high $S/N$ broadening profiles and determined the loci of the Fourier transform zeros $q_{1}$ and $q_{2}$ where the $S/N$-ratio was high enough. The values of $v \sin{i}$ were redetermined and found to be consistent with the values derived by \cite{Royer02a}. For 78 stars $q_{2}$ could be determined and the ratio $q_{2}/q_{1}$ was used as a shape parameter sensitive for solar-like differential rotation (Equator faster than Pole). 74 of the 78 stars have values of $q_{2}/q_{1}$ consistent with solid body rotation; in four of the 78 cases, values of $q_{2}/q_{1}$ are not consistent with rigid rotation. Although these stars may be binaries, none of the profiles shows signatures of a companion. The Fourier transforms do not indicate any distortions and the broadening profiles can be considered due to single objects. One of those candidates may be an extremely rapid rotator seen pole-on, but for the other three stars of spectral types as early as A6, differential rotation seems to be the most plausible explanation for the peculiar profiles.

description: In this paper we calculate the energy distribution of six cases of Vaidya-solutions in the Møller prescription. Except the energy complex of Møller for the monopole solution vanishes everywhere, for other solutions have non-zero energy component, only the energy distributions of the de Sitter and anti-de Sitter solution are independent on $v$. For the radiating dyon solution, the difference in energy complex between Møller's and Einstein's prescription is like the case of Reissner-Nordström solution.

description: We say that a weighted shift $W_α$ with (positive) weight sequence $α: α_0, α_1, \ldots$ is {\it moment infinitely divisible} (MID) if, for every $t > 0$, the shift with weight sequence $α^t: α_0^t, α_1^t, \ldots$ is subnormal. \ Assume that $W_α$ is a contraction, i.e., $0 < α_i \le 1$ for all $i \ge 0$. \ We show that such a shift $W_α$ is MID if and only if the sequence $α$ is log completely alternating. \ This enables the recapture or improvement of some previous results proved rather differently. \ We derive in particular new conditions sufficient for subnormality of a weighted shift, and each example contains implicitly an example or family of infinitely divisible Hankel matrices, many of which appear to be new.

description: Cold hydrogen gas is the raw fuel for star formation in galaxies, and its partition into atomic and molecular phases is a key quantity for galaxy evolution. In this Letter, we combine Atacama Large Millimeter/submillimeter Array and Arecibo single-dish observations to estimate the molecular-to-atomic hydrogen mass ratio for massive star-forming galaxies at $z\sim$ 0.2 extracted from the HIGHz survey, i.e., some of the most massive gas-rich systems currently known. We show that the balance between atomic and molecular hydrogen in these galaxies is similar to that of local main-sequence disks, implying that atomic hydrogen has been dominating the cold gas mass budget of star-forming galaxies for at least the past three billion years. In addition, despite harboring gas reservoirs that are more typical of objects at the cosmic noon, HIGHz galaxies host regular rotating disks with low gas velocity dispersions suggesting that high total gas fractions do not necessarily drive high turbulence in the interstellar medium.

description: We analyze the filamentarity in the Las Campanas redshift survey (LCRS) and determine the length scale at which filaments are statistically significant. The largest length-scale at which filaments are statistically significant, real objects, is between 70 to $80 h^{-1}$Mpc, for the LCRS $-3^o$ slice. Filamentary features longer than $80 h^{-1}$Mpc, though identified, are not statistically significant; they arise from chance alignments. For the five other LCRS slices, filaments of lengths $50 h^{-1}$Mpc to $70 h^{-1}$Mpc are statistically significant, but not beyond. These results indicate that while individual filaments up to $80 h^{-1}$Mpc are statistically significant, the impression of structure on larger scales is a visual effect. On scales larger than $80 h^{-1}$Mpc the filaments interconnect by statistical chance to form the filament-void network. The reality of the $80 h^{-1}$Mpc features in the $-3^o$ slice make them the longest coherent features in the LCRS. While filaments are a natural outcome of gravitational instability, any numerical model attempting to describe the formation of large scale structure in the universe must produce coherent structures on scales that match these observations.

description: Статья посвящена актуальной проблеме развития Я-концепции студентов при обучении иностранным языкам в вузе. Я-концепция определяет все аспекты поведения человека и играет ключевую роль в самоактуализации и реализации потенциала личности. Современное общество требует от человека способности к саморазвитию и постоянному личностному и профессиональному совершенствованию, что ставит новые задачи перед образовательной средой вуза, связанные с развитием Я-концепции студентов в целом и студентов педагогических направлений подготовки в частности. Цель статьи проанализировать опыт российских и зарубежных вузов по развитию Я-концепции студентов, выделить основные подходы к реализации программ целенаправленного развития Я-концепции в образовательном и воспитательном процессе вуза, определить приоритетные направления воздействия на Я-концепцию студентов, установить эффективные методы развития Я-концепции. Теоретические методы исследования включали теоретический анализ отечественной и зарубежной педагогической и психологической литературы по проблеме исследования, изучение и обобщение педагогического опыта отечественных и зарубежных вузов. В качестве эмпирических методов использовались наблюдение, включенное наблюдение (в рамках стажировок в США и Германии с 2006 по 2019 год), опрос (анкетирование, интервью). Ключевым результатом статьи является описание программы комплексного развития Я-концепции студентов педагогических направлений подготовки в процессе обучения иностранным языкам в вузе, учитывающей положительный опыт российских и зарубежных вузов по развитию Я-концепции студентов. Предлагаемая нами программа развития Я-концепции студентов при профессиональном изучении иностранного языка состоит из пяти блоков: теоретического, диагностического, проектирующего, преобразующего, апробирующего/закрепляющего и может выступать в качестве отдельного спецкурса или в качестве дополнения к традиционному курсу дисциплины «Иностранный язык» в высшем учебном заведении. Теоретическую значимость представляет обзор подходов к структуре Я-концепции в образовании, обзор научной литературы по направлениям развития Я-концепции студентов. Практическую значимость исследования составляет разработанная структура программы развития Я-концепции студентов педагогических направлений подготовки в процессе обучения иностранным языкам в вузе.
Discovery of a Synchrotron Bubble Associated with PSR J1015-5719

description: We report the discovery of a synchrotron nebula, G283.1-0.59, associated with PSR J1015-5719. Radio observations using the Molonglo Observatory Synthesis Telescope and the Australia Telescope Compact Array at 36, 16, 6, and 3 cm reveal a complex morphology. The pulsar is embedded in the "head" of the nebula with fan-shaped diffuse emission. This is connected to a circular bubble of 20" radius and a collimated tail extending over 1'. Polarization measurements show a highly ordered magnetic field in the nebula. It wraps around the edge of the head and shows an azimuthal configuration near the pulsar, then switches direction quasi-periodically near the bubble and in the tail. Together with the flat radio spectrum observed, we suggest that this system is most plausibly a pulsar wind nebula (PWN), with the head as a bow shock that has a low Mach number and the bubble as a shell expanding in a dense environment. The bubble could act as a magnetic bottle trapping the relativistic particles. A comparison with other bow-shock PWNe with higher Mach numbers shows similar structure and B-field geometry, implying that pulsar velocity may not be the most critical factor in determining the properties of these systems. We also derive analytic expressions for the projected standoff distance and shape of an inclined bow shock. It is found that the projected distance is always larger than the true distance in three dimensions. On the other hand, the projected shape is not sensitive to the inclination after rescaling with the projected standoff distance.

description: A relative motion of the normal and superfluid components of Helium II results in Kelvin-Helmholtz instability (KHI) at their common free surface. We found the exact solutions for the nonlinear stage of the development of that instability. Contrary to the usual KHI of the interface between two fluids, the dynamics of Helium II free surface allows decoupling of the governing equations with their reduction to the Laplace growth equation which has the infinite number of exact solutions including the formation of sharp cusps at free surface in a finite time.

description: Новая индустриальная революция Индустрия 4.0 определила несколько трендов в цифровых технологиях, среди которых выделяют и интернет вещей сеть цифровых приборов и устройств, взаимодействующих между собой посредством Интернета. Области приложений интернета вещей довольно обширны: промышленные технологии, удаленные технологии сервиса и быта, образовательные технологии. Современные цифровые технологии необходимо включать в содержание технологического образования в школе и при подготовке учителей технологии. Эта необходимость определяется и национальными проектами «Цифровая экономика» и «Образование», которые реализуются в настоящее время. Целью статьи является рассмотрение технологий интернета вещей как содержательного контента технологического образования будущих учителей технологии. Анализ образовательных программ и учебных курсов, посвященных интернету вещей, показал, что в технических вузах данные программы проектируются, реализуются и являются актуальными. Но в образовательных программах подготовки учителей технологии интернет вещей не рассматривается. И это является проблемой, так как школьное технологическое образование должно раскрывать современные цифровые технологии, в том числе и технологии интернета вещей, а для этого необходима соответствующая технологическая и методическая подготовка учителей технологии. Нами предложен учебный курс «Интернет вещей», который является составляющей частью модуля «Цифровые технологии» образовательных программ подготовки учителей технологии в Сыктывкарском государственном университете им. Питирима Сорокина. Целью дисциплины является ознакомление студентов с основами технологии интернета вещей. В результате освоения дисциплины студент должен: знать терминологию, технические и программные средства для реализации технологий интернета вещей; уметь применять полученные знания в учебной и профессиональной деятельности; владеть основами технологий интернета вещей. Содержание дисциплины включает четыре раздела: «Введение в интернет вещей»; «Технические средства интернета вещей»; «Сетевые технологии интернета вещей»; «Сервисы, приложения и модели интернета вещей». Лабораторный практикум дисциплины реализуется в трёх циклах занятий: изучение алгоритмов подключения различных датчиков и устройств управления к контроллеру Arduino; изучение технологий удаленного взаимодействия с контроллерами Arduino; выполнение студентами мини-проектов на основе кейс-технологии. Предложенный курс позволяет сформировать у будущих учителей технологии компетенции в области современных цифровых технологий.

description: We show that radiative coupling between two multilevel atoms having near-degenerate states can produce new interference effects in spontaneous emission. We explicitly demonstrate this possibility by considering two identical V systems each having a pair of transition dipole matrix elements which are orthogonal to each other. We discuss in detail the origin of the new interference terms and their consequences. Such terms lead to the evolution of certain coherences and excitations which would not occur otherwise. The special choice of the orientation of the transition dipole matrix elements enables us to illustrate the significance of vacuum induced coherence in multi-atom multilevel systems. These coherences can be significant in energy transfer studies.
