description: Genes linked to X or Z chromosomes, which are hemizygous in the heterogametic sex, are predicted to evolve at different rates than those on autosomes. This faster-X effect can arise either as a consequence of hemizygosity, which leads to more efficient selection for recessive beneficial mutations in the heterogametic sex, or as a consequence of reduced effective population size of the hemizygous chromosome, which leads to increased fixation of weakly deleterious mutations due to random genetic drift. Empirical results to date have suggested that, while the overall pattern across taxa is complicated, in general systems with male-heterogamy show a faster-X effect primarily attributable to more efficient selection while the only female-heterogamy taxon studied to date (birds) shows a faster-Z effect primarily attributable to increased drift. In order to test the generality of the faster-Z pattern seen in birds, we sequenced the genome of the Lepidopteran insect Bombyx huttoni, a close outgroup of the domesticated silkmoth Bombyx mori. We show that silkmoths experience faster-Z evolution, but unlike in birds, the faster-Z effect appears to be attributable to more efficient positive selection in females. These results suggest that female-heterogamy alone is unlikely to be sufficient to explain the reduced efficacy of selection on the bird Z chromosome. Instead, it is likely that a combination of patterns of dosage compensation and overall effective population size, among other factors, influence patterns of faster-Z evolution.

description: It is argued that the role of infinite dimensional asymptotic symmetry groups in gravity theories are essential for a holographic description of gravity and possibly to a resolution of the black hole information paradox. I present a simple toy model in two dimensional hyperbolic/ anti-de Sitter (AdS) space and describe, by very elementary considerations, how the asymptotic symmetry group is responsible for the entropy area law. Similar results apply also in three dimensional AdS space. The failure of the approach in higher dimensional AdS spaces is explained and resolved by considering other asymptotically noncompact homogeneous spaces.

description: We present an exponential $F(R)$ modified gravity model in the Jordan and the Einstein frame. We use a general approach in order to investigate and demonstrate the viability of the model. Apart from the general features that this models has, which actually render it viable at a first step, we address the issues of finite time singularities, Newton's law corrections and the scalaron mass. As we will evince, the model passes these latter two tests successfully and also has no finite time singularities, a feature inherent to other well studied exponential models.

description: Chronic obstructive lung disease (COPD) is a common morbidity among patients referred for aortic valve replacement. The objective of the present study is to assess trends and outcomes of COPD patients undergoing either transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) for severe aortic stenosis. We analyzed the National Inpatient Sample database from January 2012 to December 2017 using the International Classification of Diseases, 9th and 10th Revision Clinical Modifications to identify all patients with COPD aged ≥50 years who underwent either TAVR or SAVR for aortic stenosis. To account for potential bias, 1:1 propensity-matched analysis was performed. Logistic regression was used for predictors of mortality in the cohort. Linear regression was used for trend analysis. Of the total of 95,555 cases, 40,080 underwent TAVR whereas 49,985 underwent SAVR. In-hospital mortality for the propensity-matched cohorts was higher in the SAVR cohort compared to the TAVR group (4.6% vs. 2.5%; p p p TAVR has more favorable in-hospital outcomes in patients with COPD compared to SAVR.

description: The paper studies estimation of parameters of diffusion market models from historical data. The standard definition of implied volatility for these models presents its value as an implicit function of several parameters, including the risk-free interest rate. In reality, the risk free interest rate is unknown and need to be forecasted, because the option price depends on its future curve. Therefore, the standard implied volatility is {\it conditional}: it depends on the future values of the risk free rate. We study two implied parameters: the implied volatility and the implied average cumulative risk free interest rate. They can be found unconditionally from a system of two equations. We found that very simple models with random volatilities (for instance, with two point distributions) generate various volatility smiles and skews with this approach.

description: We study synchronisation properties of networks of coupled dynamical systems with interaction akin to diffusion. We assume that the isolated node dynamics possesses a forward invariant set on which it has a bounded Jacobian, then we characterise a class of coupling functions that allows for uniformly stable synchronisation in connected complex networks --- in the sense that there is an open neighbourhood of the initial conditions that is uniformly attracted towards synchronisation. Moreover, this stable synchronisation persists under perturbations to non-identical node dynamics. We illustrate the theory with numerical examples and conclude with a discussion on embedding these results in a more general framework of spectral dichotomies.

description: In 2011, the Jack H. Berryman Institute, in cooperation with the Western Association of Fish and Wildlife Agencies Cougar Working Group, published “Managing Cougars of North America” (available through www.berrymaninstitute.org or Amazon.com). Over 5,000 copies of the book were distributed. Because the science regarding management of cougars has dramatically grown over the last decade, the partners are again collaborating on a revision of the 2011 book. Currently, the chapters are undergoing a peer-review process through Human–Wildlife Interactions. Jonathan A. Jenks, South Dakota State University, is serving as the editor-in-chief for the peer-review process and will be the editor for the revised book.
We anticipate the new book will be released by the Berryman Institute Press in late 2020.

description: Несмотря на то что феномен идиолекта как индивидуального варианта языка давно привлекает внимание исследователей, в науке до сих пор отсутствует общепринятое определение идиолекта. Остаются нерешенными и многие теоретические проблемы, связанные с указанным феноменом, такие как проблемы устойчивости идиолекта, его уникальности, выделения совокупности и оценки влияния на конкретное речевое произведение тех или иных факторов идиолектного варьирования, и т.д. Вместе с тем появление в связи с развитием электронной коммуникации большого числа «непрофессиональных текстов», репрезентирующих идиолект все большего числа носителей языка, требует новых подходов к исследованию указанного феномена. В статье обосновывается необходимость исследования теоретических проблем идиолекта, а также прикладных вопросов, связанных с его изучением, в рамках отдельного лингвистического направления — корпусной идиолектологии.

description: Density functional based simulations are employed to explore magnetoelectric effects in iron-based oxides, showing a unique layered structure. We theoretically predict CaFeO2 to be a promising magnetoelectric, showing magnetically-controlled large electric polarization, possibly even above room temperature. The cross coupling between magnetic and dipolar degrees of freedom needs, as main ingredients, Fe-site spin-orbit coupling and a spin-dependent O p - Fe d hybridization, along with structural constraints related to the non-centrosymmetric point group and the peculiar geometry characterized by "flattened" FeO4 tetrahedrons. In order to enhance magnetoelectric effects, we performed a materials-design leading to a novel and optimized system, MgFeO2, where the larger O4 tetrahedral distortion leads to a stronger polarization.

description: В отечественной лингвистике антропонимы исследуются как особый тип лексики с ярко выраженной национально-культурной спецификой значения. Этнокультурный компонент семантики имен собственных определяется в терминах когнитивной лингвистики как этноконнотация или разновидность культурной коннотации — антропонимическая коннотация. Методологическим основанием настоящей работы является понимание лингвокультуры как третьей самостоятельной системы (наряду с языком и культурой), в основе которой лежит ценностный кодекс. Это требует расширения границ и изменения фокуса наблюдения, выявляющего актуальные этнокультурные смыслы и способы их репрезентации в лингвокультуре. Повседневный и фольклорный дискурс рассматриваются как системы взаимообусловленные, единое дискурсивное пространство культуры, в котором формируются этноэстетические вкусы диалектной личности. В настоящей работе приводятся полевые ономастические данные, записанные в станицах и хуторах северо-западной части Кубани последних лет, свидетельствующие о жизнеспособности традиции, транслирующей ее ценностные установки. Имя, будучи знаком этнолингвокультуры, является членом антропонимического кода, единицы которого коррелируют с дискурсивными жанрами этнокультуры. Антропонимический код вырабатывается в дискурсивной практике этнокультуры на основе ее языковых законов и закрепляется в этнокультурном сознании как истинный. Формы имени, используемые в дискурсах разного типа, образуют культурную парадигму имени, к которой апеллирует говорящий в процессе речевой деятельности. Этнокультурное и этноэстетическое взаимосвязаны в этнокультурном восприятии — инородные имена отторгаются, наделяются отрицательными коннотациями. Свое осмысляется как этнокультурный образец и приобретает статус эстетического знака.

description: We present results from the deepest Herschel-PACS (Photodetector Array Camera and Spectrometer) far-infrared blank field extragalactic survey, obtained by combining observations of the GOODS (Great Observatories Origins Deep Survey) fields from the PACS Evolutionary Probe (PEP) and GOODS-Herschel key programmes. We describe data reduction and the construction of images and catalogues. In the deepest parts of the GOODS-S field, the catalogues reach 3-sigma depths of 0.9, 0.6 and 1.3 mJy at 70, 100 and 160 um, respectively, and resolve ~75% of the cosmic infrared background at 100um and 160um into individually detected sources. We use these data to estimate the PACS confusion noise, to derive the PACS number counts down to unprecedented depths and to determine the infrared luminosity function of galaxies down to LIR=10^11 Lsun at z~1 and LIR=10^12 Lsun at z~2, respectively. For the infrared luminosity function of galaxies, our deep Herschel far-infrared observations are fundamental because they provide more accurate infrared luminosity estimates than those previously obtained from mid-infrared observations. Maps and source catalogues (>3-sigma) are now publicly released. Combined with the large wealth of multi-wavelength data available for the GOODS fields, these data provide a powerful new tool for studying galaxy evolution over a broad range of redshifts.

В каждой из трёх моделей выделяются варианты с описанием семантических отношений между компонентами сложных терминов, причём количество вариантов в моделях различно. Сложные термины немецкой метрологической системы для удобства анализа подразделяются на две подгруппы: термины с общим обозначением понятия измерительного прибора / измерительной техники и термины, обозначающие конкретные измерительные приборы. Выявлено расхождение в количестве основ, участвующих в образовании терминов первой и второй подгруппы. Отмечается высокий уровень участия интернациональных основ в образовании сложных немецких терминов, а среди них так называемых связанных основ -meter и -graph.

description: A thin film of ferromagnetically ordered material proximate to the surface of a three-dimensional topological insulator explicitly breaks the time-reversal symmetry of the surface states. For an out-of-plane ferromagnetic order parameter on the surface, the parity is also broken, since the Dirac fermions become massive. This leads in turn to the generation of a topological Chern-Simons term by quantum fluctuations. On the other hand, for an in-plane magnetization the surface states remain gapless for the non-interacting Dirac fermions. In this work we study the possibility of spontaneous breaking of parity due to a dynamical gap generation on the surface in the presence of a local, Hubbard-like, interaction of strength $g$ between the Dirac fermions. A gap and a Chern-Simons term are generated for $g$ larger than some critical value, g_c, provided the number of Dirac fermions, $N$, is odd. For an even number of Dirac fermions the masses are generated in pairs having opposite signs, and no Chern-Simons term is generated. We discuss our results in the context of recent experiments in EuS/Bi_2Se_3 heterostructures.

description: We derive distance priors from Planck first data release, and examine their impact on dark energy constraints from current observational data. We give the mean values and covariance matrix of {R, l_a, Ω_b h^2, n_s}, which give an efficient summary of Planck data. The CMB shift parameters are R=\sqrt{Ω_m H_0^2}\,r(z_*), and l_a=πr(z_*)/r_s(z_*), where z_* is the redshift at the last scattering surface, and r(z_*) and r_s(z_*) denote our comoving distance to z_* and sound horizon at z_* respectively. We find that Planck distance priors are significantly tighter than those from WMAP9. However, adding Planck distance priors does not lead to significantly improved dark energy constraints using current data, compared to adding WMAP9 distance priors. This is because Planck data appear to favor a higher matter density and lower Hubble constant, in tension with most of the other current cosmological data sets. Adding Planck distance priors to current data leads to a marginal inconsistency with a cosmological constant in a flat universe.

description: Recent climate warming in the Arctic is enhancing microbial decomposition of soil organic matter, which may result in globally significant greenhouse gas releases to the atmosphere. To better predict future impacts, bacterial and fungal community structures in both the bulk soil and the rhizosphere of Arctic birch, Betula glandulosa, were determined in control, greenhouse summer warming, and annual factorial nitrogen (N) and phosphate (P) addition treatments twelve years after their establishment. DNA sequence analyses at multiple taxonomic levels consistently indicated substantial bulk soil and rhizosphere microbial community differences among the fertilization treatments but no significant greenhouse effects. These results suggest that climate warming will likely increase the activity rates of soil microbial decomposers but without substantially altering the structure of either the bacterial or fungal communities. Differential abundance testing revealed changes in ectomycorrhizal fungal species of the genus Thelephora in both bulk soil and rhizosphere, with increases in their relative abundance in P and N + P amended plots compared with warming and controls. Because birch is the principal low Arctic ectomycorrhizal host, our results suggest that these fungi may promote this shrub’s competitiveness where tundra soil nutrient availability is enhanced by warming or other means, ultimately contributing to arctic vegetation “greening.”

description: Due to the technological progress of the last decades, Community Detection has become a major topic in machine learning. However, there is still a huge gap between practical and theoretical results, as theoretically optimal procedures often lack a feasible implementation and vice versa. This paper aims to close this gap and presents a novel algorithm that is both numerically and statistically efficient. Our procedure uses a test of homogeneity to compute adaptive weights describing local communities. The approach was inspired by the Adaptive Weights Community Detection (AWCD) algorithm by [2]. This algorithm delivered some promising results on artificial and real-life data, but our theoretical analysis reveals its performance to be suboptimal on a stochastic block model. In particular, the involved estimators are biased and the procedure does not work for sparse graphs. We propose significant modifications, addressing both shortcomings and achieving a nearly optimal rate of strong consistency on the stochastic block model. Our theoretical results are illustrated and validated by numerical experiments.

Авторы анализируют то, как в общественном сознании того времени и в литературе, которая является его отражением, воспринимается такая важная общественная фигура, как врач. Рассматривается социальный статус врача, его профессиональная деятельность, его взаимоотношения с пациентами и представителями различных социальных групп. Особое внимание уделяется тем трудностям, которые возникают на пути прогресса медицины, и противостоянию врача-учёного общественным предрассудкам.  Литературоведческий анализ проводится на широком историческом фоне, авторы подкрепляют свои положения историческими фактами. Особый интерес для авторов представляет развитие медицинской терминологии, поэтому в статье, в связи с рассматриваемым материалом,  анализируются некоторые клинические термины.

На материале более тысячи языковых единиц (отдельные лексемы, фразы, синтаксические конструкты), с использованием нескольких методов: сплошной выборки, структурного, функционального, интерпретационно-стилистиче­ского и др., анализируется язык двух персонажей в сопоставительном плане как своеобразный элемент идиостиля писателя-билингва. Подчеркивается многослойность и разнообразие в оформлении речевых характеристик, делается попытка связать использование проанализированных языковых единиц с историко-культурной составляющей и языковой личностью самого автора. Делается вывод о том, что Игнатов и Лейбе, два совершенно противоположных по гражданской позиции человека, в своем «речевом поведении» в романе сильно отличаются, имея при этом общие черты в речи как монологической, так и диалогической.

Hierarchical models are important because of the well-known mapping between their phases and those of models with short range hopping in higher dimensions, and also because the renormalization group can be applied exactly without the approximations that generally are required in other models. In the hierarchical Anderson model we find a finite critical disorder strength Wc where the average inverse participation ratio goes to zero; at small disorder W < Wc the model lies in a delocalized phase. This result is based on numerical calculation of the inverse participation ratio in the infinite volume limit using an exact renormalization group approach facilitated by the model's hierarchical structure. Our results are consistent with the presence of an Anderson transition in short-range models with D > 2 dimensions, which was predicted using renormalization group arguments. Our finding should stimulate interest in the hierarchical Anderson model as a simplified and tractable model of the Anderson localization transition which occurs in finite-dimensional systems with short-range hopping.

description: We study a composite millicharged dark matter model. The dark matter is in the form of pion-like objects emerging from a higher scale QCD-like theory. We present two distinct possibilities with interesting phenomenological consequences based on the choice of the parameters. In the first one, the dark matter is produced non-thermally and it could potentially account for the 130 GeV Fermi photon line via decays of the "dark pions". We estimate the self-interaction cross section which might play an important role both in changing the dark matter halo profile at the center of the galaxy and in making the dark matter warmer. In the second version the dark matter is produced via the freeze-in mechanism. Finally we impose all possible astrophysical, cosmological and experimental constraints. We study in detail generic constraints on millicharged dark matter that can arise from anomalous isotope searches of different elements and we show why constraints based on direct searches from underground detectors are not generally valid.

Libsharp - spherical harmonic transforms revisited
Creators: name: Reinecke, Martin

Publisher: name: arXiv
Year: 2013
Subjects: subject: Computational Physics (physics.comp-ph)

description: We present libsharp, a code library for spherical harmonic transforms (SHTs), which evolved from the libpsht library, addressing several of its shortcomings, such as adding MPI support for distributed memory systems and SHTs of fields with arbitrary spin, but also supporting new developments in CPU instruction sets like the Advanced Vector Extensions (AVX) or fused multiply-accumulate (FMA) instructions. The library is implemented in portable C99 and provides an interface that can be easily accessed from other programming languages such as C++, Fortran, Python etc. Generally, libsharp's performance is at least on par with that of its predecessor; however, significant improvements were made to the algorithms for scalar SHTs, which are roughly twice as fast when using the same CPU capabilities. The library is available at http://sourceforge.net/projects/libsharp/ under the terms of the GNU General Public License.

description: We study the magnetization dynamics in a ferromagnet-insulator-superconductor tunnel junction and the associated buildup of the electrical polarization. We show that for an open circuit, the induced voltage varies strongly and nonmonotonically with the precessional frequency, and can be enhanced significantly by the superconducting correlations. For frequencies much smaller or much larger than the superconducting gap, the voltage drops to zero, while when these two energy scales are comparable, the voltage is peaked at a value determined by the driving frequency. We comment on the potential utilization of the effect for the low-temperature spatially-resolved spectroscopy of magnetic dynamics.

description: During heavy ion collisions, high temperatures and strong magnetic fields are generated. We employ the gauge-gravity duality to study the N_f=2 QCD phase diagram under these extreme conditions in the quenched approximation, in particular we use the non-antipodal Sakai-Sugimoto model (SSM). We take the different coupling of up and down flavours to the magnetic field into account geometrically, resulting in a split of the chiral phase transition according to flavour. We discuss the influence of the magnetic field on the chiral temperatures -in physical GeV units- in terms of the choice of the confinement scale in the model, extending hereby our elsewhere presented discussion of fixing the non-antipodal SSM parameters to the deconfinement phase. The flavour-dependent (T,L,eB) phase diagram, with variable asymptotic brane-antibrane separation L, is also presented, as a direct generalization of the known (T,L) phase diagram of the non-antipodal SSM at zero magnetic field. In particular, for sufficiently small L we are probing a NJL-like boundary field theory in which case we do find results very reminiscent of the predictions in NJL models.

 Notes. Coleolaelaps asiaticus was described from Kazakhstan, and is now recorded for only the second time. All the specimens have come from beetles in the genus Polyphylla (Karg & Rössner, 1999). This species may be distinguished from most other species of Coleolaelaps by the presence of two postero-lateral setae on genu IV, the relatively short dorsal shield setae in the J series, and the short peritreme, which reaches only to the posterior margin of coxa I.

description: We propose and theoretically investigate a hybrid system composed of a crystal of trapped ions coupled to a cloud of ultracold fermions. The ions form a periodic lattice and induce a band structure in the atoms. This system combines the advantages of scalability and tunability of ultracold atomic systems with the high fidelity operations and detection offered by trapped ion systems. It also features close analogies to natural solid-state systems, as the atomic degrees of freedom couple to phonons of the ion lattice, thereby emulating a solid-state system. Starting from the microscopic many-body Hamiltonian, we derive the low energy Hamiltonian including the atomic band structure and give an expression for the atom-phonon coupling. We discuss possible experimental implementations such as a Peierls-like transition into a period-doubled dimerized state.

Time Evolution of Entanglement Entropy from Black Hole Interiors

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We compute the time-dependent entanglement entropy of a CFT which starts in relatively simple initial states. The initial states are the thermofield double for thermal states, dual to eternal black holes, and a particular pure state, dual to a black hole formed by gravitational collapse. The entanglement entropy grows linearly in time. This linear growth is directly related to the growth of the black hole interior measured along "nice" spatial slices. These nice slices probe the spacelike direction in the interior, at a fixed special value of the interior time. In the case of a two-dimensional CFT, we match the bulk and boundary computations of the entanglement entropy. We briefly discuss the long time behavior of various correlators, computed via classical geodesics or surfaces, and point out that their exponential decay comes about for similar reasons. We also present the time evolution of the wavefunction in the tensor network description.

description: We present new constraints on coupled dark energy from the recent measurements of the Cosmic Microwave Background Anisotropies from the Planck satellite mission. We found that a coupled dark energy model is fully compatible with the Planck measurements, deriving a weak bound on the dark matter-dark energy coupling parameter ξ=-0.49^{+0.19}_{-0.31} at 68% c.l.. Moreover if Planck data are fitted to a coupled dark energy scenario, the constraint on the Hubble constant is relaxed to H_0=72.1^{+3.2}_{-2.3} km/s/Mpc, solving the tension with the Hubble Space Telescope value. We show that a combined Planck+HST analysis provides significant evidence for coupled dark energy finding a non-zero value for the coupling parameter ξ, with -0.90< ξ

Average Rate of Downlink Heterogeneous Cellular Networks over Generalized Fading Channels - A Stochastic Geometry Approach

description: In this paper, we introduce an analytical framework to compute the average rate of downlink heterogeneous cellular networks. The framework leverages recent application of stochastic geometry to other-cell interference modeling and analysis. The heterogeneous cellular network is modeled as the superposition of many tiers of Base Stations (BSs) having different transmit power, density, path-loss exponent, fading parameters and distribution, and unequal biasing for flexible tier association. A long-term averaged maximum biased-received-power tier association is considered. The positions of the BSs in each tier are modeled as points of an independent Poisson Point Process (PPP). Under these assumptions, we introduce a new analytical methodology to evaluate the average rate, which avoids the computation of the Coverage Probability (Pcov) and needs only the Moment Generating Function (MGF) of the aggregate interference at the probe mobile terminal. The distinguishable characteristic of our analytical methodology consists in providing a tractable and numerically efficient framework that is applicable to general fading distributions, including composite fading channels with small- and mid-scale fluctuations. In addition, our method can efficiently handle correlated Log-Normal shadowing with little increase of the computational complexity. The proposed MGF-based approach needs the computation of either a single or a two-fold numerical integral, thus reducing the complexity of Pcov-based frameworks, which require, for general fading distributions, the computation of a four-fold integral.
