description: Статья посвящена анализу связи между способом визуализации, присущим иконе, и обоснованием суверенной власти в политике. Сопоставление этих двух областей и контекстов очень важно для лучшего понимания теологических предпосылок политической власти икон, которая впервые стала явной уже в первых иконоборческих кризисах. Анализ исходит из констатации того, что особенностью иконы, в отличие от светской живописи, является невидимый прообраз иконописного образа, так что икона, визуализируя невидимое, в то же время служит образцом боговоплощения в качестве перехода невидимого в видимое. Подчёркивается, что такое обретение плоти является также особой формой отношения между божественным и человеческим, идеальным и земным, которое, однако, радикально отличается от структуры платоновской метафизики. Первое концептуальное представление иконы в качестве образца боговоплощения потребовало особого описания проблемы, которое было основано на понятии экономии (oikonomia).

description: We discuss three possible ways to address quantum physics behind chiral magnetic effect and electric charge fluctuation patterns in heavy ion collisions. The first one makes use of P-parity violation probed by local order parameters, the second considers CME in quantum measurement theory framework and the third way is to study P-odd * P-odd contributions to P-even observables. In the latter approach relevant form-factor is extracted and computed for weak magnetic field in confinement region and for free quarks in strong field regime. It is shown that the effect is negligible in the former case. We also discuss saturation effect - charge fluctuation asymmetry for free fermions reaches constant value at asymptotically large fields.

Noncoplanar spin canting in lightly-doped ferromagnetic Kondo lattice model on a triangular lattice

description: Effect of the coupling to mobile carriers on the 120$^\circ$ antiferromagnetic state is investigated in a ferromagnetic Kondo lattice model on a frustrated triangular lattice. Using a variational calculation for various spin orderings up to a four-site unit cell, we identify the ground-state phase diagram with focusing on the lightly-doped region. We find that an electron doping from the band bottom immediately destabilizes a 120$^\circ$ coplanar antiferromagnetic order and induces a noncoplanar three-sublattice ordering accompanied by an intervening phase separation. This noncoplanar phase has an umbrella-type spin configuration with a net magnetic moment and a finite spin scalar chirality. This spin-canting state emerges in competition between the antiferromagnetic superexchange interaction and the ferromagnetic double-exchange interaction under geometrical frustration. In contrast, a hole doping from the band top retains the 120$^\circ$-ordered state up to a finite doping concentration and does not lead to a noncolpanar ordering.

A rogue consensus : a limit to US foreign policy polarization?
Creators: name: Kotb, Shereen
Publisher: name: University of British Columbia
Year: 2019

description: The leading prognosis of US foreign policymaking since the Vietnam War has been that ideology and partisanship have driven a wedge between American policymakers, causing them to have increasingly polarized foreign policy views and positions. The purpose of this study is to conduct a unique investigation of the effect of these factors in shaping foreign policymaking towards rogue states. In an attempt to test the limits of US polarization, this paper aims to investigate the patterns of legislative behavior towards rogue states in the US Senate from 1991 to 2017. This paper uses logistic and zero-inflated Poisson estimations on an original dataset to test the impact of ideology and partisanship on two areas of legislative behaviour: voting on legislation targeting rogue states and the sponsorship and cosponsorship of these bills. The former tests whether there exist differences in policy preferences towards rogues, while the latter tests whether there are differences in the level of engagement on the issue. The results of the paper reveal a surprisingly high degree of consensus among policymakers in their voting behaviour; most bills brought to a vote are passed with unanimous or almost-unanimous consensus. Meanwhile, an examination of the sponsorship and cosponsorship of these bills indicates that Republicans and conservatives are more active in proposing rogue-related legislation than Democrats and liberals. The results suggest that while partisanship and ideology may create differences in policy preferences on issues relating to rogue states, Republicans and conservatives are more active in crafting legislation. At the same time, their Democratic and liberal counterparts face few incentives to vote against them.
Properties of Turbulence in the Very Local Interstellar Clouds

description: We have investigated the degree to which turbulence in the Very Local Interstellar Clouds resembles the highly-studied turbulence in the solar corona and the solar wind. The turbulence diagnostics for the Local Clouds are the absorption line widths measured along 32 lines of sight to nearby stars, yielding measurements for 53 absorption components (Redfield and Linsky 2004). We have tested whether the Local Cloud turbulence has the following properties of turbulence in the solar corona or the solar wind: (a) velocity fluctuations mainly perpendicular to the average magnetic field, (b) a temperature anisotropy in the sense that the perpendicular temperature is larger than the parallel temperature (or at least enhanced relative to expectation), and (c) an ion temperature which is dependent on the ion Larmor radius, in the sense that more massive ions have higher temperatures. Our analysis of the data does not show compelling evidence for any of these properties in Local Cloud turbulence, indicating possible differences with heliospheric plasmas. In the case of anisotropy of velocity fluctuations, although the expected observational signature is not seen, we cannot exclude the possibility of relatively high degrees of anisotropy (anisotropy parameter $ε\sim 0.50 - 0.70$), if some other process in the the Local Clouds is causing variations in the turbulent line width from one line of sight to another. We briefly consider possible reasons for differences between coronal and solar wind turbulence and that in the Local Clouds.

On Cooperative Beamforming Based on Second-Order Statistics of Channel State Information

description: Cooperative beamforming in relay networks is considered, in which a source transmits to its destination with the help of a set of cooperating nodes. The source first transmits locally. The cooperating nodes that receive the source signal retransmit a weighted version of it in an amplify-and-forward (AF) fashion. Assuming knowledge of the second-order statistics of the channel state information, beamforming weights are determined so that the signal-to-noise ratio (SNR) at the destination is maximized subject to two different power constraints, i.e., a total (source and relay) power constraint, and individual relay power constraints. For the former constraint, the original problem is transformed into a problem of one variable, which can be solved via Newton's method. For the latter constraint, the original problem is transformed into a homogeneous quadratically constrained quadratic programming (QCQP) problem. In this case, it is shown that when the number of relays does not exceed three the global solution can always be constructed via semidefinite programming (SDP) relaxation and the matrix rank-one decomposition technique. For the cases in which the SDP relaxation does not generate a rank one solution, two methods are proposed to solve the problem: the first one is based on the coordinate descent method, and the second one transforms the QCQP problem into an infinity norm maximization problem in which a smooth finite norm approximation can lead to the solution using the augmented Lagrangian method.

Geodesics of electrically and magnetically charged test particles in the Reissner-Nordström space-time: analytical solutions

description: We present the full set of analytical solutions of the geodesic equations of charged test particles in the Reissner-Nordström space-time in terms of the Weierstraß $\wp$, $σ$ and $ζ$ elliptic functions. Based on the study of the polynomials in the $\vartheta$ and $r$ equations we characterize the motion of test particles and discuss their properties. The motion of charged test particles in the Reissner-Nordström space-time is compared with the motion of neutral test particles in the field of a gravitomagnetic monopole. Electrically or magnetically charged particles in the Reissner-Nordström space-time with magnetic or electric charges, respectively, move on cones similar to neutral test particles in the Taub-NUT space-times.

description: We use a theoretical model of the $γ~d \to ~K^+ K^- ~n ~p $ reaction adapted to the experiment done at LEPS where a peak was observed and associated to the $Θ^{+}(1540)$ pentaquark. The study shows that the method used in the experiment to associate momenta to the undetected proton and neutron, together with the chosen cuts, necessarily creates an artificial broad peak in the assumed $K^+ n$ invariant mass in the region of the claimed $Θ^{+}(1540)$, such that the remaining strength seen for the experimental peak is compatible with a fluctuation of 2$σ$ significance.

description: Although relative errors can readily be calculated, the absolute astrometric accuracy of the source positions in the Chandra Source Catalog (CSC), Version 1.0, is a priori unknown. However, the cross-match with stellar objects from the Sloan Digital Sky Survey (SDSS) offers the opportunity to compare the apparent separations of the cross-matched pairs with the formally calculated errors. The analysis of these data allowed us to derive a value of 0.16" for the residual absolute astrometric error in CSC positions. This error will be added to the published position errors in the CSC from now on, starting with CSC, Version 1.1.

Hole pairing from attraction of opposite chirality spin vortices: Non-BCS superconductivity in Underdoped Cuprates

description: Within a gauge approach to the t-J model, we propose a new, non-BCS mechanism of superconductivity for underdoped cuprates. We implement the no-double occupancy constraint with a (semionic) slave-particle formalism. The dopant generates a vortex-like quantum distortion of the AF background centered on the empty sites, with opposite chirality for cores on the two Néel sublattices. Empty sites are described in terms of spinless fermionic holons and the long-range attraction between spin vortices on two opposite Néel sublattices is the holon pairing force, leading eventually to SC. The spin fluctuations are described by bosonic spinons with a gap generated by scattering on spin vortices. Due to the occupation constraint, there is a gauge attraction between holon and spinon, binding them into a physical hole. Through gauge interaction the spin vortex attraction induces the formation of spin-singlet RVB pairs reducing the spinon gap. Lowering T, there are two crossovers as precursors of the SC transition: at the higher one a gas of holon pairs appears, reducing the hole spectral weight, while at the lower one a gas of spinon pairs also appears, giving rise to a gas of incoherent preformed hole pairs with magnetic vortices in the plasma phase, supporting a Nernst signal. At an even lower T the hole pairs become coherent and SC appears beyond a critical doping. The proposed SC mechanism is not of the BCS-type, because it involves a gain in kinetic energy (lowering of spinon gap) and it is "almost" of the classical 3D XY-type. Since both the spinon gap and the holon pairing originate from the same term in the slave-particle representation of the t-J model, this approach incorporates a strong interplay between AF and SC, giving rise to a universal relation between Tc and the energy of the resonance mode, as observed in neutron scattering experiments.

description: We prove that it is NP-hard to decide whether two points in a polygonal domain with holes can be connected by a wire. This implies that finding any approximation to the shortest path for a long snake amidst polygonal obstacles is NP-hard. On the positive side, we show that snake's problem is "length-tractable": if the snake is "fat", i.e., its length/width ratio is small, the shortest path can be computed in polynomial time.

description: In theory we pursue a sustainable development, but in reality we do not. An economy based on continuous growth, which evidently is not sustainable, is however the priority model almost everywhere. If we really aim at implementing sustainability, then we must radically change our economic model. Sufficiency - which calls for individuals mainly from so-called “developed countries” not to consume more than is really needed - may offer a useful alternative. We can still find some - last - examples of indigenous peoples living in a sufficient manner, all of them nowadays in those “developing countries”. We could learn at least from them that it is possible to live differently, i.e., in harmony with ourselves and our environment. This would pave the way for their - and for our all - protection, as well as the manner in which we understand at present development politics.

Das fast überall priorisier-te Wirtschaftsmodell basiert auf ständigem Wachstum, was sicherlich nicht nachhaltig ist. Wenn wir wirklich beabsichtigen, Nachhaltigkeit zu implementieren, müssen wir unser Wirtschaftsmodell radikal ändern. Suffizienz - was für Individuen hauptsächlich aus so genannten entwickelten Länder bedeutet, nicht mehr als notwendig zu konsumieren - könnte eine nützliche Alternative sein. Wir können noch - letzte - Beispiele von indigenen Völkern finden, alle in so genannten Entwicklungsländern, die suffizient leben. Wie könnten von ihnen lernen, dass es möglich wäre, in Harmonie mit uns und mit unserer Umwelt zu leben. Dies würde den Weg zu ihrem - und zu unserem allen - Schutz ändern, so wie die Art, wie wir Entwicklungspolitik aktuell verstehen.

description: We investigate network exploration by random walks defined via stationary and adaptive transition probabilities on large graphs. We derive an exact formula valid for arbitrary graphs and arbitrary walks with stationary transition probabilities (STP), for the average number of discovered edges as function of time. We show that for STP walks site and edge exploration obey the same scaling $\sim n^λ$ as function of time $n$. Therefore, edge exploration on graphs with many loops is always lagging compared to site exploration, the revealed graph being sparse until almost all nodes have been discovered. We then introduce the Edge Explorer Model, which presents a novel class of adaptive walks, that perform faithful network discovery even on dense networks.

description: We report remarkable similarities in the output signal of two distinct out-of- equilibrium physical systems - earthquakes and the intermittent acoustic noise emitted by crum- pled plastic sheets - Biaxially Oriented Polypropylene (BOPP) films. We show that both signals share several statistical properties including the distribution of energy, distribution of energy in- crements for distinct time scales, distribution of return intervals and correlations in the magnitude and sign of energy increments. This analogy is consistent with the concept of universality in com- plex systems and could provide some insight on the mechanisms behind the complex behavior of earthquakes.

description: Many fewer women than men try the entrepreneurial way in Germany. Any explanation for this phenomenon must be complex, as many factors are relevant for its production. Among other things, it is possible to speculate on sexual/gender discrimination, on more or less voluntary decisions of women or on different starting conditions for potential entrepreneurs. We assume that these options are closely related. This paper will concentrate, though, on the third alternative. Its focus will be set on the “family field,” or more precisely, on the role of family law in hindering women from trying self-employment. The family field in Germany has not evolved in the sense of gender equality along with all other areas of society - e.g., entrepreneurship. No gender equality is possible if the family field is not part of it. This paper analyses causes and consequences for this phenomenon.

Es wird angenommen, dass diese Alternative eng zusammenhängen. Dieser Aufsatz wird sich dennoch auf die dritte konzentrieren. Sein Schwerpunkt wird auf dem Familienbereich, insbesondere auf dem Familienrecht als Hindernis für Frauen und Entrepreneurship. Der Familienbereich hat sich nicht mit der gesamten Gesellschaft hinsichtlich Gender Gleichstellung - z.B. Entrepreneurship - entwickelt. Dennoch ist keine Gender Gleichstellung möglich wenn das Familienfeld nicht dazu gehört. Dieser Aufsatz untersucht die Ursachen und Folgen dieses Phänomens.

SUSY Dark Matter In Light Of CDMS/XENON Limits

description: In this talk we briefly review the current CDMS/XENON constraints on the neutralino dark matter in three popular supersymmetric models: the minimal (MSSM), the next-to-minimal (NMSSM) and the nearly minimal (nMSSM). The constraints from the dark matter relic density and various collider experiments are also taken into account. The conclusion is that for each model the current CDMS/XENON limits can readily exclude a large part of the parameter space allowed by other constraints and the future SuperCDMS or XENON100 can cover most of the allowed parameter space. The implication for the Higgs search at the LHC is also discussed. It is found that in the currently allowed parameter space the MSSM charged Higgs boson is quite unlikely to be discovered at the LHC while the neutral Higgs bosons $H$ and $A$ may be accessible at the LHC in the parameter space with a large $μ$ parameter.

description: Organolithium compounds have been used successfully in flow chemistry since the recent past. Most of the studies dealt with the use in halogen-lithium exchanges. So far, however, there has been a lack of use in substitution reactions. The use of flow microreactors makes the highly reactive organolithium compounds more controllable and thus creates new synthetic possibilities.

Coping with chronic stress : an investigation of the social context

description: Social relationships are important for physical and mental health, but the specific mechanisms involved are much less clear. The stress and coping process is one pathway through which social relationships could influence health and wellbeing. Drawing on a social contextual model of stress and coping, I investigated specific ways that social relationships shape and are shaped by adjustment to chronic stress. Study 1 examined the role of perceived social support availability in a sample of people living with spinal cord injury (SCI) who were coping with chronic pain symptoms. Pain catastrophizing has been consistently associated with worse adjustment to chronic pain, therefore Study 1 focused on understanding the role of support in mitigating the extent and impact of this maladaptive coping response. This intensive longitudinal study found that tangible support was associated with less pain catastrophizing overall and smaller increases in pain when catastrophizing did occur. Implications for people living with SCI and other chronic pain populations are discussed. Study 2 examined the role of stress appraisals in long-term relationship outcomes. Although traditional cognitive models of stress predict that those who appraise stressors as very serious are at greatest risk of poor outcomes, findings in Study 2 support a social contextual model in which shared appraisals have a protective effect on marital outcomes. In this study of stepfamily couples, a joint view of their most serious family problems was associated with a reduced risk of separation or divorce across the next 20 years. Implications for preventive interventions for highly stressed families are discussed. Finally, Study 3 examined how adjustment to chronic stress in one family member affects others in the family system. In this longitudinal study of families caring for a child with a complex chronic health condition, mothers’ experiences of posttraumatic growth were found to predict fewer behavioural problems in their healthy children over time. These findings support a family systems approach in which the benefits of posttraumatic growth in the face of adversity can also extend from mothers to children. Together these studies underscore some of the mechanisms through which social relationships may promote better health and wellbeing.
title: МОТИВ ВРАЧЕВАНИЯ БОЛЕЗНИ И ЕГО ВИЗУАЛИЗАЦИЯ НА ПРИМЕРЕ «ИСТОРИИ АРМЕНИИ» АГАТАНГЕЛОСА

description: В статье детально рассматриваются мотивы болезни и врачевания на основе «Истории Армении» Агатангелоса. Этот текст является продуктом христианской социальной памяти, а его переводы на разные языки (сирийский, греческий) указывают на его транснациональный характер. В ходе описания названных мотивов анализируются их визуализации в армянских средневековых рукописях, миниатюрах и в живописи. Описания болезни и врачевания армянского царя Трдата III и аристократии стали ключевыми мотивами в «Истории Армении» Агатангелоса, поскольку они играли важную роль в воздействии на раннесредневековых читателей. Визуализации деталей и персонажей текста «Истории Армении» можно обнаружить в разных «форматах» искусства – таких как миниатюры, стеллы, гобелены, картины и т. д. Анализ материала показал, что мотив болезни и её врачевания стал ключевым генератором в истории принятия христианства армянами. Избиение 37 девушек-христианок, среди которых были святые Гаянэ и Рипсимэ, стало причиной болезни царя Трдата III. Процесс исцеления царя проходит разные этапы (например, облачение тела). Кроме того, сама болезнь становится причиной того, что сестра царя, Хосровадухт, через сон вспомнила о Григории Просветителе, о будущем лекаре, вылечившем аристократию не только на телесном, но и на духовном уровне.

description: We report the observation of a large 1/f noise in the ferromagnetic insulating state (FMI) of a hole doped manganite single crystal of La0.80Ca0.20MnO3 which manifests hopping conductivity in presence of a Coulomb gap. The temperature dependent noise magnitude shows a deep within the FMI state, there is a sharp freeze out of the noise magnitude with temperature on cooling. As the material enters the FMI state, the noise becomes non-Gaussian as seen through probability density function and second spectra. It is proposed to arise from charge fluctuations in a correlated glassy phase of the polaronic carriers which develop in these systems as reported in recent simulation studies.

description: Публикация продолжает серию статей, посвящённых исследованию традиционного русского города как религиозной визуально-семиотической системы. Здесь я публикую перечень русских надвратных храмов, построенных в период с XI по XXI век. Этот каталог позволяет оценить интенсивность строительства таких храмов в разные исторические периоды. Максимальное число построенных надвратных церквей приходится на XVII век, а наибольшая скорость их постройки – на XXI. Также приведены сведения о посвящениях русских надвратных храмов с учётом того, что посвящение одного и того же храма могло меняться. Большая часть храмов сгруппирована по категориям посвящений: пророкам, апостолам, святым, праздникам и иконам. Кроме того, в качестве примера локальной истории надвратных храмов представлена информация о времени постройки таких храмов в Великом Новгороде и на территориях, культурно тяготеющих к нему.

description: Magnetoresistivity $ρ_{xx}$ and $ρ_{xy}$ and the acoustoelectronic effects are measured in $p$-Si/SiGe/Si with an impurity concentration $p$ = 2 $\times $ 10$^{11}$ cm$^{-2}$ in the temperature range 0.3-2.0 K and an tilted magnetic field up to 18 T. The dependence of the effective $g$-factor on the angle of magnetic field tilt $θ$ to the normal to the plane of a two dimensional $p$-Si/SiGe/Si channel is determined. A first order ferromagnet-paramagnet phase transition is observed in the magnetic fields corresponding to a filling factor $ν$ = 2 at $θ\approx $ 59$^\textrm{o}$-60$^\textrm{o}$.

Coherent semiclassical states for loop quantum cosmology

description: The spatially flat Friedman-Robertson-Walker (FRW) cosmological model with a massless scalar field in loop quantum cosmology admits a description in terms of a completely solvable model. This has been used to prove that: i) the quantum bounce that replaces the big bang singularity is generic; ii) there is an upper bound on the energy density for all states and iii) semiclassical states at late times had to be semiclassical before the bounce. Here we consider a family of exact solutions to the theory, corresponding to generalized coherent Gaussian and squeezed states. We analyze the behavior of basic physical observables and impose restrictions on the states based on physical considerations. These turn out to be enough to select, from all the generalized coherent states, those that behave semiclassical at late times. We study then the properties of such states near the bounce where the most `quantum behavior' is expected. As it turns out, the states remain sharply peaked and semiclassical at the bounce and the dynamics is very well approximated by the `effective theory' throughout the time evolution. We compare the semiclassicality properties of squeezed states to those of the Gaussian semiclassical states and conclude that the Gaussians are better behaved. In particular, the asymmetry in the relative fluctuations before and after the bounce are negligible, thus ruling out claims of so called `cosmic forgetfulness'.

description: Much of the progress in our understanding of dynamo mechanisms has been made within the theoretical framework of magnetohydrodynamics (MHD). However, for sufficiently diffuse media, the Hall effect eventually becomes non-negligible. We present results from three dimensional simulations of the Hall-MHD equations subjected to random non-helical forcing. We study the role of the Hall effect in the dynamo efficiency for different values of the Hall parameter, using a pseudospectral code to achieve exponentially fast convergence. We also study energy transfer rates among spatial scales to determine the relative importance of the various nonlinear effects in the dynamo process and in the energy cascade. The Hall effect produces a reduction of the direct energy cascade at scales larger than the Hall scale, and therefore leads to smaller energy dissipation rates. Finally, we present results stemming from simulations at large magnetic Prandtl numbers, which is the relevant regime in hot and diffuse media such a the interstellar medium.

description: The gravitational-wave instability of r-modes in rapidly rotating compact stars is believed to spin them down to angular frequencies of about a tenth of the Kepler frequency soon after their birth in a Supernova. We point out that the r-mode perturbation also impacts the neutrino cooling and viscosity in hot compact stars via processes that restore weak equilibrium. We illustrate this fact with a simple model of spin-down due to gravitational wave emission in compact stars composed entirely of three-flavor degenerate quark matter (a strange quark star). Non-equilibrium neutrino cooling of this oscillating fluid matter is quantified. Our results imply that a consistent treatment of thermal and spin-frequency evolution of a young and hot compact star is a requisite in estimating the persistence of gravitational waves from such a source.

description: We predict the existence of a novel class of multidimensional light localizations in out-of-equilibrium ferroelectric crystals. In two dimensions, the non-diffracting beams form at arbitrary low power level and propagate even when their width is well below the optical wavelength. In three dimensions, a novel form of subwavelength light bullets is found. The effects emerge when compositionally disordered crystals are brought to their metastable glassy state, and can have a profound impact on super-resolved imaging and ultra-dense optical storage, while resembling many features of the so-called metamaterials, as the suppression of evanescent waves.
