description: Extrasolar super-Earths (1-10 M$_{\earth}$) are likely to exist with a wide range of atmospheres. Some super-Earths may be able to retain massive hydrogen-rich atmospheres. Others might never accumulate hydrogen or experience significant escape of lightweight elements, resulting in atmospheres more like those of the terrestrial planets in our Solar System. We examine how an observer could differentiate between hydrogen-rich and hydrogen-poor atmospheres by modeling super-Earth emission and transmission spectra, and we find that discrimination is possible by observing the transmission spectrum alone. An Earth-like atmosphere, composed of mostly heavy elements and molecules, will have a very weak transmission signal due to its small atmospheric scale height (since the scale height is inversely proportional to molecular weight). On the other hand, a large hydrogen-rich atmosphere reveals a relatively large transmission signal. The super Earth emission spectrum can additionally contrain the atmospheric composition and temperature structure. Super-Earths with massive hydrogen atmospheres will reveal strong spectral features due to water, whereas those that have lost most of their hydrogen (and have no liquid ocean) will be marked by CO$_2$ features and a lack of H$_2$O. We apply our study specifically to the low-mass planet orbiting an M star, Gl 581c ($M sin i$ = 5 M$_{\earth}$), although our conclusions are relevant for super-Earths in general. The ability to distinguish hydrogen-rich atmospheres might be essential for interpreting mass and radius observations of planets in the transition between rocky super-Earths and Neptune-like planets.

description: Gamma-ray Bursts (GRB) were discovered by satellite-based detectors as powerful sources of transient $γ$-ray emission. The Fermi satellite detected an increasing number of these events with its dedicated Gamma-ray Burst Monitor (GBM), some of which were associated with high energy photons $(E > 10\, \mathrm{GeV})$, by the Large Area Telescope (LAT). More recently, follow-up observations by Cherenkov telescopes detected very high energy emission $(E > 100\, \mathrm{GeV})$ from GRBs, opening up a new observational window with implications on the interpretation of their central engines and on the propagation of very energetic photons across the Universe. Here, we use the data published in the 2nd Fermi-LAT Gamma Ray Burst Catalogue to characterise the duration, luminosity, redshift and light curve of the high energy GRB emission. We extrapolate these properties to the very high energy domain, comparing the results with available observations and with the potential of future instruments. We use observed and simulated GRB populations to estimate the chances of detection with wide-field ground-based $γ$-ray instruments. Our analysis aims to evaluate the opportunities of the Southern Wide-field-of-view Gamma-ray Observatory (SWGO), to be installed in the Southern Hemisphere, to complement CTA. We show that a low-energy observing threshold $(E_{low} < 200\, \mathrm{GeV})$, with good point source sensitivity $(F_{lim} \approx 10^{-11}\, \mathrm{erg\, cm^{-2}\, s^{-1}}$ in $1\, \mathrm{yr})$, are optimal requirements to work as a GRB trigger facility and to probe the burst spectral properties down to time scales as short as $10\, \mathrm{s}$, accessing a time domain that will not be available to IACT instruments.

description: Stephan's Quintet (SQ) is a nearby compact galaxy group and a perfect laboratory for studying the process of galaxy evolution through galaxy harassment and interaction. By analysing the kinematics of SQ we aim to provide an increased understanding of the group, the history of the interactions, their cause and effect, and the details regarding the physical processes occurring as galaxies interact. We have studied the ionised gas and stellar kinematics using the Large Binocular Telescope, and the molecular gas kinematics via CO using the IRAM 30m. Large areas of the group have been mapped and analysed. We obtain a total ionised gas mass in the regions chosen for closer analysis of 20.1$\pm$0.2x10^10 Msun and a total H2 gas mass of 21$\pm$2x10^9 Msun in the observed area (spectra integrated over the velocity range of SQ), while the star-forming (SF) clouds show an impressive complexity, with gas congregations at multiple velocities throughout the group. We map the large-scale nuclear wind in NGC7319 and its decoupled gas and stellar disk. With our high resolution data we can, for the first time, reveal the Seyfert 1 nature of NGC7319 and fit the narrow-line and broad-line regions. While the 12CO(1-0) map shows significant emission in the area of NGC7319, the bridge, and the SF ridge, the 12CO(2-1) emission shows a prevalence to the SF ridge, an area south of the NGC7318 pair, and an extension towards NGC7317 - connecting NGC7317 to the centre of the group, indicating a previous interaction. NGC7317 may also be a prime candidate for studies of the process of galaxy harassment. Furthermore, we connect the kinematical structures in SQ to the history of the group and the ongoing interaction with NGC7318B. Through our extensive observations of SQ we trace the kinematics and evolution of the complex processes and structures occurring in this nearby interactive group. [Abstract abridged]

Различают два вида билингвизма: русско-национальный и национально-русский, в соответствии с этим дифференцируется и методика билингвального обучения. Методика, основанная на русско-национальном билингвизме, использует русский язык как основной язык обучения с обращением к национальному языку как вспомогательному. Методика, основанная на национально-русском билингвизме, предполагает обучение на родном (нерусском) языке, но с активным использованием русского в целях интеграции в систему российского образования. Основным элементом методики в обоих случаях является работа с двуязычными текстами, в частности, математическими задачами.

description: In this paper, we propose a novel kind of Josephson-Energy Suppression Pump (JESP) controlled by a fully magnetic flux drive. The device presented here is composed of two superconducting loops interrupted at one side by superconducting nanowires which are joined together by a superconducting island. The phase difference developed at the edges of the nanowires by means of the magnetic flux threading the loops can collapse their Cooper condensates, leading to complete suppression of the Josephson energies. This mechanism allows to greatly reduce the leakage current when performing Cooper pair pumping by a pure magnetic pumping cycle without involving any gate modulation. The pumping capability of the JESP is studied through a master equation approach in the non-adiabatic case.

description: Dyson published in 1990 a proof due to Feynman of the Maxwell equations. This proof is based on the assumption of simple commutation relations between position and velocity. We first study a nonrelativistic particle using Feynman formalism. We show that Poincaré's magnetic angular momentum and Dirac magnetic monopole are the direct consequences of the structure of the sO(3) Lie algebra in Feynman formalism. Then we show how to extend this formalism to the dual momentum space with the aim of introducing Noncommutative Quantum Mechanics which was recently the subject of a wide range of works from particle physics to condensed matter physics.

Автор акцентирует внимание на обстоятельства введения статей 280.1 (в 2013 г.) и 280.2 (в 2020 г.) в Уголовный кодекс РФ. Анализ правовых норм выявил их юридические дефекты, что подтверждается неоднозначной следственно-судебной практикой. После конституционной реформы-2020 была введена уголовная ответственность за «отчуждение части территории», однако моделирование возможного преступного деяния по ст. 280.2 УК РФ показало несостоятельность нормы. Кроме того, формально-догматический подход показал казуистический характер данных статей и коллизию с нормами международного права. Предлагается изъять из УК РФ статьи 280.1 и 280.2.

description: In this paper we present a catalog of 4584 eclipsing binaries observed during the first two years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binary candidates, detection of hither-to unknown eclipsing systems, determination of the ephemerides, the validation and triage process, and the derivation of heuristic estimates for the ephemerides. Instead of keeping to the widely used discrete classes, we propose a binary star morphology classification based on a dimensionality reduction algorithm. Finally, we present statistical properties of the sample, we qualitatively estimate completeness, and discuss the results. The work presented here is organized and performed within the TESS Eclipsing Binary Working Group, an open group of professional and citizen scientists; we conclude by describing ongoing work and future goals for the group. The catalog is available from http://tessEBs.villanova.edu and from MAST.

description: Twisted graphene multilayers provide tunable platforms to engineer flat bands and exploit the associated strongly correlated physics. The two-dimensional nature of these systems makes them suitable for encapsulation by materials that break specific symmetries. In this context, recently discovered two-dimensional helimagnets, such as the multiferroic monolayer NiI$_2$, are specially appealing for breaking time-reversal and inversion symmetries due to their nontrivial spin textures. Here we show that this spin texture can be imprinted on the electronic structure of twisted bilayer graphene by proximity effect. We discuss the dependence of the imprinted spin texture on the wave-vector of the helical structure, and on the strength of the effective local exchange field. Based on these results we discuss the nature of the superconducting instabilities that can take place in helimagnet encapsulated twisted bilayer graphene. Our results put forward helimagnetic encapsulation as a powerful way of designing spin-textured flat band systems, providing a starting point to engineer a new family of correlated moire states.

description: We present muon spin lattice relaxation measurements in the V15 spin 1/2 molecular nano-magnet. We find that the relaxation rate in low magnetic fields (<5 kG) is temperature independent below ~10 K, implying that the molecular spin is dynamically fluctuating down to 12 mK. These measurements show that the fluctuation time increases as the temperature is decreased and saturates at a value of ~6 nsec at low temperatures. The fluctuations are attributed to V15 molecular spin dynamics perpendicular to the applied magnetic field direction, induced by coupling between the molecular spin and nuclear spin bath in the system.

description: In this paper we present a stochastic homogenization result for a  class of Hilbert space evolutionary gradient systems driven by a quadratic dissipation potential and a Λ-convex energy functional featuring random and rapidly oscillating coefficients. Specific examples included in the result are Allen--Cahn type equations and evolutionary equations driven by the p-Laplace operator with p ∈ in (1, ∞).  The homogenization procedure we apply is based on a stochastic two-scale convergence approach.  In particular, we define a stochastic unfolding operator which can be considered as a random counterpart of the well-established notion of periodic unfolding.  The stochastic unfolding procedure grants a very convenient method for homogenization problems defined in terms of  (Λ-)convex functionals.

description: Probabilistic state-estimation approaches offer a principled foundation for designing localization systems, because they naturally integrate sequences of imperfect motion and exteroceptive sensor data. Recently, probabilistic localization systems utilizing appearance-invariant visual place recognition (VPR) methods as the primary exteroceptive sensor have demonstrated state-of-the-art performance in the presence of substantial appearance change. However, existing systems 1) do not fully utilize odometry data within the motion models, and 2) are unable to handle route deviations, due to the assumption that query traverses exactly repeat the mapping traverse. To address these shortcomings, we present a new probabilistic topometric localization system which incorporates full 3-dof odometry into the motion model and furthermore, adds an "off-map" state within the state-estimation framework, allowing query traverses which feature significant route detours from the reference map to be successfully localized. We perform extensive evaluation on multiple query traverses from the Oxford RobotCar dataset exhibiting both significant appearance change and deviations from routes previously traversed. In particular, we evaluate performance on two practically relevant localization tasks: loop closure detection and global localization. Our approach achieves major performance improvements over both existing and improved state-of-the-art systems.

Competition between final-state and pairing-gap effects in the radio-frequency spectra of ultracold Fermi atoms

description: The radio-frequency spectra of ultracold Fermi atoms are calculated by including final-state interactions affecting the excited level of the transition, and compared with the experimental data. A competition is revealed between pairing-gap effects which tend to push the oscillator strength toward high frequencies away from threshold, and final-state effects which tend instead to pull the oscillator strength toward threshold. As a result of this competition, the position of the peak of the spectra cannot be simply related to the value of the pairing gap, whose extraction thus requires support from theoretical calculations.

description: Oscillating magnetic fields and field gradients can be used to implement single-qubit rotations and entangling multi-qubit quantum gates for trapped-ion quantum information processing (QIP). With fields generated by currents in microfabricated surface-electrode traps, it should be possible to achieve gate speeds that are comparable to those of optically induced gates for realistic distances between the ion crystal and the electrode surface. Magnetic-field-mediated gates have the potential to significantly reduce the overhead in laser beam control and motional state initialization compared to current QIP experiments with trapped ions and will eliminate spontaneous scattering, a fundamental source of decoherence in laser-mediated gates.

description: An unstable gravitino with lifetime longer than $10^{26}$ sec or so has been proposed as a possible dark matter candidate in supergravity models with R-parity breaking. We find a natural realization of this idea in the minimal supersymmetric left-right models where left-right symmetry breaking scale in the few TeV range. It is known that in these models, R-parity must break in order to have parity breaking as required by low energy weak interactions. The sub-eV neutrino masses imply that R-parity breaking effects in this model must be highly suppressed. This in turn makes the gravitino LSP long lived enough, so that it becomes the dark matter of the Universe. It also allows detectable displaced vertices at the LHC from NLSP decays. We present a detailed analysis of the model and some aspects of its rich phenomenology.

Daily rings in otoliths of sockeye salmon (Oncorhynchus nerka) and their relationship to growth
Creators: name: Wilson, Kenneth H.
Publisher: name: University of British Columbia
Year: 2010

description: This study reports the occurrence of daily rings in the otoliths of Oncorhynchus nerka fry and examines their relationship to growth. In experiment 1, sockeye salmon fry were collected from the Fulton River spawning channel at Babine Lake, British Columbia in May 1978. The fish were reared for 26 days in enclosures in the spawning channel and were sampled every seven to ten days. Sagittae were removed from 25 fish from each sample, and the growth rings in one otolith from each fish were counted. A regression of the number of rings on the number of days since capture showed that these rings are, on average, formed daily, beginning at the time of emergence. A number of possible technical and biological causes of variation in ring counts within and between samples are considered. In Experiment 2, sockeye salmon fry were reared in the laboratory from fertilized eggs taken in the fall of 1978 at the Weaver Creek spawning channel near Mission, British Columbia. A random sample of 64 of these fry was marked to enable identification of individuals. Each individual was weighed initially on June 6 or 8, again on July 6, and surviving fish were weighed a third time on July 20. After a final weighing, sagittae were removed and a standard otolith radius was determined by counting back the appropriate number of daily rings which corresponded to each weight. The regression of £n otolith radius on £n fish weight was linear, and had an R2 of 0.92, which demonstrates a relationship between the mean width of a daily ring in sockeye salmon fry sagittae, and a mean daily change in the weight of the fry. Using this regression line, we back-calculated the previous weight of the individual fish from the corresponding otolith radius and a latter fish weight and otolith radius and found the errors to be relatively small — in the order of 15 per cent.

description: A major goal of vaccines is to induce functional immune memory, and efforts to improve the efficacy of vaccines targeting memory CTLs have revealed an important immunoregulatory role of rapamycin, a specific mTOR inhibitor. While inflammatory cytokines are critical for memory CTLs formation, it is unknown if cytokines such as IL-12 mediate rapamycin's regulation during infection. Inhibition of mTOR by rapamycin represses CTL expansion but enhances central memory during vaccinia virus infection in mice. Without IL-12, immunoregulatory effects of rapamycin on CTL expansion and subsequent memory formation are diminished, yet present compared to CTLs not treated with rapamycin. In infected mice, rapamycin directly enhances IL-12 signaling in WT CTLs by upregulating IL-12 receptor-B2 and STAT4 phosphorylation. Furthermore, secondary expansion of rapamycin-regulated memory CTLs in IL-12 receptor knockouts is impaired and resultant secondary memory CTLs are abolished. This indicates that interplay between cytokines and adjuvants should be considered during vaccine design.

description: Atomistic defect engineering through the pulsed laser epitaxy of perovskite transition metal oxides offers facile control of their emergent opto-electromagnetic and energy properties. Among the various perovskite oxides, EuTiO3 exhibits a strong coupling between the lattice, electronic, and magnetic degrees of freedom. This coupling is highly susceptible to atomistic defects. In this study, we investigated the magnetic phase of EuTiO$_3$ epitaxial thin films via systematic defect engineering. A magnetic phase transition from an antiferromagnet to a ferromagnet was observed when the unit cell volume of EuTiO3 expanded due to the introduction of Eu-O vacancies. Optical spectroscopy and density functional theory calculations show that the change in the electronic structure as the ferromagnetic phase emerges can be attributed to the weakened Eu-Ti-Eu super-exchange interaction and the developed ferromagnetic Eu-O-Eu interaction. Facile defect engineering in EuTiO$_3$ thin films facilitates understanding and tailoring of their magnetic ground state.

description: We have implemented a chemical evolution model on the parallel AP3M+SPH DEVA code which we use to perform high resolution simulations of spiral galaxy formation. It includes feedback by SNII and SNIa using the Qij matrix formalism. We also include a diffusion mechanism that spreads newly introduced metals. The gas cooling rate depends on its specific composition. We study the stellar populations of the resulting bulges finding a potential scenario where they seem to be composed of two populations: an old, metal poor, $α$-enriched population, formed in a multiclump scenario at the beginning of the simulation and a younger one, formed by slow accretion of satellites or gas, possibly from the disk due to instabilities.

description: External gravitational fields induce phase factors in the wave functions of particles. The phases are exact to first order in the background gravitational field, are manifestly covariant and gauge invariant and provide a useful tool for the study of spin-gravity coupling and of the optics of particles in gravitational or inertial fields.

Interoperability is a key concern for our open-access repositories. One important foundation of this potential to interoperate with other systems is the creation and exposure of descriptive metadata, formatted according to standard "profiles" (a "profile" can be considered to be an agreed set of metadata properties and constraints or rules).

The metadata profiles used in repositories range from the very general to the more specific. The classic example of the former would be OAI-DC, which is the basic default profile produced by default by all repositories which allow metadata to be harvested via the ubiquitous OAI-PMH protocol. The more specific end of the range of profiles includes profiles which are designed to operate within a particular geo-political context (e.g. OpenAIRE; JPCOAR; RIOXX), or within a particular scholarly domain.

The global knowledge commons at the heart of COAR's mission certainly transcends geo-political borders, but there are other "borders" - for example between disciplines - and we need to be prepared to operate across these too.

The challenge for COAR, then, is to recognise and embrace the development of a rich and varied "economy" of metadata profiles, while at the same time developing a strategy to ensure that a sufficient level of interoperability between them can be identified and achieved.
The use of dextrans as particulate tracers in respiratory epithelial permeability studies
Creators: name: Forster, Allan Bruce Burton
Publisher: name: University of British Columbia
Year: 2010

description: These experiments were designed to test the suitability of dextrans as alternate light and electron microscopic tracers to horseradish peroxidase (HRP) in studies of respiratory epithelial permeability in control and cigarette smoke-exposed guinea pigs. Nine animals were utilized initially to establish the most effective means of preserving highly water-soluble dextran while adequately maintaining airway cell ultrastructure. The perfusion-nebulization fixation and carbohydrate retention techniques developed were then used on the twenty-six guinea pigs in the permeability study. Five animals served as controls, while others were exposed to the dextran tracer, smoke from 10 cigarettes, or both. Intratracheal tracer instillations of sonicated preparations of unlabelled or either FITC- or iron-labelled dextran T10 or T40 were carried out 1/2-hour after smoke exposure. All dextrans could be visualized light-microscopically along the respiratory epithelium of airways and lung parenchyma by the Mowry-Millican technique, a modified alcoholic periodic acid-schiff (PAS) stain. As witnessed in previous HRP studies, some post-mortem tracer diffusion was seen, and no difference in dextran epithelial penetration was noted between smoked and sham-smoked animals. At the electron microscopic level, treatment of guinea pig trachea and lung with aldehyde-OsO₄-lead citrate fixative cocktail preserved the unlabelled dextran as irregular, highly electron-dense aggregates of particles along the luminal surfaces only of airways of control guinea pigs. One-half of the animals in the smoke-exposed group showed penetration of dextran between the tracheal epithelial cells. Incomplete tracer dissolution prior to instillation, as shown by negative staining of the instillates, is thought to be responsible for this inconsistency. No intrapulmonary or alveolar trans-epithelial tracer transport could be detected. FITC-dextrans presented the additional advantages of qualitative detection by fluorescence-differentiated interference contrast (DIC) microscopy and quantitative detection by spectrophotofluoro-metric means. Iron-dextrans exhibited too large a molecular size for practical use with smoke-exposed guinea pig tracheobronchial epithelium. We conclude that dextrans provide distinct advantages over HRP in terms of low price, inertness, and size versatility, as light and electron microscopic tracers.

description: We show that the combined effects of spin-orbit, monoclinic distortion, and p-d hybridization in tetrahedrally coordinated Fe in LaOFeAs invalidates the naive Hund's rule filling of the Fe d-levels. The two highest occupied levels have one electron each but as a result of the p-d hybridization have very different on-site repulsions. As a result, electrons in the upper level are more itinerant while those in the lower level are more localized. It is the xy-projection of the spin in the lower level that orders antiferromagnetically as the z-components of the spins in the two levels is shown to be vanishingly small in the ground state. The resulting magnetic moment is highly anisotropic with an in-plane value of $0.25-0.35μ_B$ per Fe and a z-projection of $0.06μ_B$, both of which are in agreement with experiment. As a consequence, we arrive the minimal model that describes the electronic properties of LaOFeAs.

description: We present a new texture of neutrino mass matrix having three complex relations among its elements and study in detail the phenomenological implications. A characteristic feature of the resulting neutrino mass matrix is that the atmospheric neutrino mixing angle is predicted to lie in a very narrow region near $45^{\circ}$. We illustrate how such a form of the neutrino mass matrix can be realized using the non-Abelian flavor symmetry $A_4$ in the framework of type-I+II seesaw mechanism.
