description: Energetic flares and associated coronal mass ejections (CMEs) from young magnetically active solar-like stars can play a critical role in setting conditions for atmospheric escape as well as penetration of accelerated particles into their atmospheres that promotes formation of biologically relevant molecules. We have used the observationally reconstructed magnetic field of the 0.7 Gyr young Sun's twin, k 1 Ceti, to study the effects of CME deflections in the magnetic corona of the young Sun and their effects on the impact frequency on the early Venus, Earth, and Mars. We find that the coronal magnetic field deflects the CMEs toward the astrospheric current sheet. This effect suggests that CMEs tend to propagate within a small cone about the ecliptic plane increasing the impact frequency of CMEs with planetary magnetospheres near this plane to ∼30% or by a factor of 6 as compared to previous estimate by Airapetian et al. Our model has important implications for the rise of prebiotic chemistry on early terrestrial planets as well as terrestrial-type exoplanets around young G-K dwarfs.

description: Let $R$ be an Artin algebra and $e$ an idempotent of $R$. Assume that ${\rm Tor}_i^{eRe}(Re,G)=0$ for any $G\in{\rm GProj} eRe$ and $i$ sufficiently large. Necessary and sufficient conditions are given for the Schur functor $S_e$ to induce a triangle-equivalence $\mathbb{D}_{def}(R)\simeq\mathbb{D}_{def}(eRe)$. Combine this with a result of Psaroudakis-Skartsaterhagen-Solberg [29], we provide necessary and sufficient conditions for the singular equivalence $\mathbb{D}_{sg}(R)\simeq\mathbb{D}_{sg}(eRe)$ to restrict to a triangle-equivalence $\underline{{\rm GProj} R}\simeq\underline{{\rm GProj} eRe}$. Applying these to the triangular matrix algebra $T=\left( \begin{array}{cc} A & M \quad 0 & B \end{array} \right)$, corresponding results between candidate categories of $T$ and $A$ (resp. $B$) are obtained. As a consequence, we infer Gorensteinness and CM-freeness of $T$ from those of $A$ (resp. $B$). Some concrete examples are given to indicate one can realise the Gorenstein defect category of a triangular matrix algebra as the singularity category of one of its corner algabras.

description: Most soils in West Africa are acutely deﬁcient in Phosphorus (P); therefore, sustainable P management is important in order to restore their capacity to supply adequate P, improve crop P use eﬃciency, and sustain crop production. Thus, we investigated the impacts of alternative management practices on soil available phosphorus (Pcal), soil P balance (Pb), and crop P use eﬃciency (Pe) under maize-cotton rotation system on four weathered soils [Ferric Lixisol (FL), Eutric Plinthosol (EP), Haplic Lixisols (HL), and Plinthic Lixisol (PL)] of West Africa. To this end, on-farm trials were set up in a strip-split plot layout, where 2 levels of tillage (contour ridge tillage, and reduced tillage) were considered as mainplot factor, and sub-plot factors included 2 levels of crop residue management (with and without), and 2 levels of N fertiliser doses (control and recommended dose). After 5 cycles of maize-cotton rotation (2012–2016), Pcal in the topsoil layer were signiﬁcantly aﬀected by single and interactive eﬀects of soil and residue management. The highest content of Pcal was recorded on HL (64.4 kg ha-1), while both FL and EP had the lowest content (27.1 kg ha-1). Returning crop residues caused an 34.8 % increase in Pcal when averaged across soil types. Also, both Pe and Pb of cotton and maize varied according to soil and crop residue management and their interactions. Pe trends of both cotton and maize were ranked as: HL > PL > EP > FL. As expected, Pb showed the reversed pattern. With the retention of crop residues on surface soils, Pe of cotton and maize improved by 8 % and 8.5 %, respectively. We concluded that soils derived from volcanic materials (high clay content) attributed to poor topsoil Pcal and crop Pe compared to those derived from sandstone (low clay content) materials. Additionally, retention of crop residues led to improved Pcal and crop Pe by acting as an additional source of soil P and protecting surface soil from erosion. Hence, we suggest that returning residues can be a viable measure to manage soil P and sustain crop production in weathered soils of West Africa.

description: Three distinct scales are identified in the excitation spectrum of the gluon field around a static quark-antiquark pair as the color source separation R is varied. The spectrum, with string-like excitations on the largest length scales of 2-3 fm, provides clues in its rich fine structure for developing an effective bosonic string description. New results are reported from the three-dimensional Z(2) and SU(2) gauge models, providing further insight into the mechanism of bosonic string formation. The precocious onset of string-like behavior in the Casimir energy of the static quark-antiquark ground state is observed below R=1 fm where most of the string eigenmodes do not exist and the few stable excitations above the ground state are displaced. We find no firm theoretical foundation for the widely held view of discovering string formation from high precision ground state properties below the 1 fm scale.

description: We study the direct interaction of an antisymmetric Kalb-Ramond field with a scalar particle derived from a gauge principle. The method outlined in this paper to define a covariant derivative is applied to a simple model leading to a linear coupling between the fields. Although no conserved Noether charge exists, a conserved topological current comes out from the antisymmetry properties of the Kalb-Ramond field. Some interesting features of this current are pointed out.

description: The construct validity of a behaviorally anchored rating scale (BARS) and a behavioral checklist was examined for evaluation of performance in leaderless group discussions. The assessors consisted of 12 graduate students in industrial/organizational psychology who were randomly assigned to use the behavioral checklist or the BARS format. Performance ratings were made of 12 ratees in both assigned and nonassigned role leaderless group discussions. The ratings were analyzed with a multitrait-multimethod approach using analysis of variance (Dickinson 1977; 1984) ~ Convergent validity and discriminant validity were found for the assigned discussion, whereas only discriminant validity was found for the nonassigned discussion. Low method bias was found in the ratings for both discussions. Comparisons of the two formats showed the checklist to yield higher discriminant validity for the nonassigned discussion while the BARS had higher validity for the assigned discussion. These findings suggested that different formats are appropriate for evaluating performance in different exercises. Additional research was recommended for improving leaderless group discussions and for determining appropriate formats'

It is shown that for a regular black hole, these energy-momentum complexes give the same energy distribution. This supports Cooperstock hypothesis and also Aguirregabbiria et al. conclusions. Further, we evaluate energy distribution using M$\ddot{o}$ller's prescription. This does not exactly coincide with ELLPW energy expression but, at large distances, they become same.

description: Modeling collective motion in non-conservative systems, such as granular materials, is difficult since a general microscopic-to-macroscopic approach is not available: there is no Hamiltonian, no known stationary densities in phase space, not a known small set of relevant variables. Phenomenological coarse-grained models are a good alternative, provided that one has identified a few slow observables and collected a sufficient amount of data for their dynamics. Here we study the case of a vibrofluidized dense granular material. The experimental study of a tracer, dispersed into the media, showed the evidence of many time scales: fast ballistic, intermediate caged, slow superdiffusive, very slow diffusive. A numerical investigation has demonstrated that tracer's superdiffusion is related to slow rotating drifts of the granular medium. Here we offer a deeper insight into the slow scales of the granular medium, and propose a new phenomenological model for such a "secular" dynamics. Based upon the model for the granular medium, we also introduce a model for the tracer (fast and slow) dynamics, which consists in a stochastic system of equations for three coupled variables, and is therefore more refined and successful than previous models.

Diese Entwicklung führt jedoch zu einer zunehmenden Jargonisierung und Vulgarisierung, die in der Linguistik kritisiert wird. Diese Tendenzen haben mittlerweile auch Massenmedien und Literatur, einschließlich der zeitgenössischen Lyrik, erfasst, wo viele Jargonismen und Argotismen zu finden sind. Die Begriffe Jargon, Argot und Slang werden oft synonym verwendet, obwohl es Versuche gibt, sie zu differenzieren. Die substandardsprachliche Lexik in der russischen Gegenwartslyrik ist heterogen und stammt aus verschiedenen Quellen, einschließlich der Jargons sozialer Gruppen und thematischer Gruppen des Prostorečie und Mat.

description: The spin-half pyrochlore Heisenberg antiferromagnet (PHAF) is one of the most challenging problems in the field of highly frustrated quantum magnetism. Stimulated by the seminal paper of M.~Planck [M.~Planck, Verhandl. Dtsch. phys. Ges. {\bf 2}, 202-204 (1900)] we calculate thermodynamic properties of this model by interpolating between the low- and high-temperature behavior. For that we follow ideas developed in detail by B.~Bernu and G.~Misguich and use for the interpolation the entropy exploiting sum rules [the ``entropy method'' (EM)]. We complement the EM results for the specific heat, the entropy, and the susceptibility by corresponding results obtained by the finite-temperature Lanczos method (FTLM) for a finite lattice of $N=32$ sites as well as by the high-temperature expansion (HTE) data. We find that due to pronounced finite-size effects the FTLM data for $N=32$ are not representative for the infinite system below $T \approx 0.7$. A similar restriction to $T \gtrsim 0.7$ holds for the HTE designed for the infinite PHAF. By contrast, the EM provides reliable data for the whole temperature region for the infinite PHAF. We find evidence for a gapless spectrum leading to a power-law behavior of the specific heat at low $T$ and for a single maximum in $c(T)$ at $T\approx 0.25$. For the susceptibility $χ(T)$ we find indications of a monotonous increase of $χ$ upon decreasing of $T$ reaching $χ_0 \approx 0.1$ at $T=0$. Moreover, the EM allows to estimate the ground-state energy to $e_0\approx -0.52$.

Color illusion as a spatial binding problem

Publisher: name: American University

description: Illusions are often considered to be a misperception of the physical world. We present a different framework for illusions: in non-illusory conditions, healthy brains construct a single, consistent representation from the physiological processes that encode the world; illusions, in contrast, are conditions where the brain constructs conflicting representations of the world. We contend that the conditions for illusions often arise for color vision because of the multifaceted aspects of color in relation to space, and that many color illusions arise from the juxtaposition and selective recombination (i.e. the binding) of these aspects of color/spatial information. We discuss three spatial aspects of color: modes of appearance, color versus color contrast, and information at different spatial scales.

description: We investigate spatial and temporal cross-correlations between streamwise and normal velocity components in three shear flows: a low-dimensional model for vortex-streak interactions, direct numerical simulations for a nearly homogeneous shear flow and experimental data for a turbulent boundary layer. A driving of streamwise streaks by streamwise vortices gives rise to a temporal asymmetry in the short time correlation. Close to the wall or the bounding surface in the free-slip situations, this asymmetry is identified. Further away from the boundaries the asymmetry becomes weaker and changes character, indicating the prevalence of other processes. The systematic variation of the asymmetry measure may be used as a complementary indicator to separate different layers in turbulent shear flows. The location of the extrema at different streamwise displacements can be used to read off the mean advection speed; it differs from the mean streamwise velocity because of asymmetries in the normal extension of the structures.

description: Recycling has proven to be a necessity in sustaining life on the planet and thus is being explored by organisations in the hopes of coming up with new means of sustainability. It can be as small as one person recycling one single plastic cup per, or as large as a multinational company handling their waste the best way possible. Regardless, these are the steps to clean air, clean water, and longer lifespan for every species on earth. Proper recycling requires the society to know how and what to recycle. As such, it seems like a good idea to provide people with instant feedback on their recycling both of their role in the recycling community, as well as the trends of the community as a whole. The purpose of this report is to assess not only the economical, environmental and social aspects of two potential hardware or software combinations that serve the purpose of waste tracking and feedback, but also to ascertain whether the project as a whole will be effective at increasing recycling, and what can be done to aid this. Personal interviews as well as online surveys have shown that most people would be interested in getting an instant feedback on what they have done, in other words: how much they have helped toward a brighter future. The surveys have also shown that taking advantage of social aspects to aid in the effectiveness of this project is also a good idea ( detailed later in the report ). Providing instant feedback will not be easy and without costs. Extensive research has provided two of the best hardware and software companies who have worked on tracking waste and giving feedback. Drawing from a series of interviews with previous users of such products, it can be concluded that although the Intelex software will require the additional aspects of a system to install on as well as an attachable scale, it still is the most sustainable and cheapest product currently on the market. Through assessing the triple bottom line assessment, carefully going over the economical, environmental and social aspects of each product. This report details why Intelex software is the correct choice, and that installing such a system in the SUB at UBC would indeed be an effective method of increasing recycling rates.

The detectors were fabricated at the Lawrence Berkeley National Laboratory and the University of South Dakota, using crystals grown at the University of South Dakota. They survived long-distance transportation and multiple thermal cycles in both cryogenic liquids and showed reasonable leakage currents and spectroscopic performance. Also discussed are the pros and cons of using thin amorphous semiconductor materials as an alternative contact technology in large-scale germanium experiments searching for physics beyond the Standard Model.

description: We are concerned with the numerical solution of a unified first order hyperbolic formulation of continuum mechanics that originates from the work of Godunov, Peshkov and Romenski (GPR model) and which is an extension of nonlinear hyperelasticity that is able to describe simultaneously nonlinear elasto-plastic solids at large strain, as well as viscous and ideal fluids. The proposed governing PDE system also contains the effect of heat conduction and can be shown to be symmetric and thermodynamically compatible. In this paper we extend the GPR model to the simulation of nonlinear dynamic rupture processes and material fatigue effects, by adding a new scalar variable to the governing PDE system. This extra parameter describes the material damage and is governed by an advection-reaction equation, where the stiff and highly nonlinear reaction mechanisms depend on the ratio of the local von Mises stress to the yield stress of the material. The stiff reaction mechanisms are integrated in time via an efficient exponential time integrator. Due to the multiple space-time scales, the model is solved on space-time adaptive Cartesian meshes using high order discontinuous Galerkin finite element schemes with a posteriori subcell finite volume limiting. A key feature of our new model is the use of a twofold diffuse interface approach that allows the cracks to form anywhere and at any time, independently of the chosen computational grid, without requiring that the geometry of the rupture fault be known a priori. We furthermore make use of a scalar volume fraction function that indicates whether a given point is inside the solid or outside, allowing the description of solids of arbitrarily complex shape.

description: We present an interpretation of loop quantization in the framework of lattice gauge theory. Within this context the lack of appropriate notions of effective theories and renormalization group flow exhibit loop quantization as an incomplete framework. This interpretation includes a construction of embedded spin foam models which does not rely on the choice of any auxiliary structure (e.g. triangulation) and has the following straightforward consequences: (1) The values of the coupling constants need to be those of an UV-attractive fixed point (2) The kinematics of canonical loop quantization and embedded spin foam models are compatible (3) The weights assigned to embedded spin foams are independent of the 2-polyhedron used to regularize the path integral, $|J|_x = |J|_{x'}$ (4) An area spectrum with edge contributions proportional to $l_{\rm PL}^2 (j+1 / 2)$ is not compatible with embedded spin foam models and/or canonical loop quantization

From Heaven to Earth : 'Cultural Idealism' and 'Moral Realism' as Chinese contributions to global international relations
Creators: name: Acharya, Amitav
Publisher: name: American University
Year: 2023

description: The discipline of International Relations (IR) is increasingly being criticized for ignoring and marginalizing states and societies outside of the core countries of the West. The idea of a 'Global IR' has been proposed since 2014 a pathway toward a bridging the 'West and the Rest' divide and thus develop a more inclusive discipline, recognizing its multiple and diverse foundations. At the same time, there is a trend toward developing theories, or 'schools', on a national or regional basis, the leading examples of which come from China. This article examines some theoretical constructs emerging in China, such as the 'Relational Theory' of Qin Yaqing, who is the foundational scholar in the 'Chinese School of IR', the Tianxia ('all under Heaven') concept as applied to IR and world order by Zhao Tingyang, and 'Moral Realism' of Yan Xuetong, who is the leading figure of the 'Tsinghua School'. To many scholars, both inside and outside China, the relationship among the various Chinese approaches and their overall contribution to the IR field remain unclear. Without claiming to capture all their nuances and complexity, this article hopes to stimulate a conversation among scholars, Chinese and foreign, with a view to generate greater clarity and highlight their importance to the study of IR. I argue that while making important contributions, the Chinese approaches to International Relations Theory (IRT) also face a number of challenges. This includes the need for them to offer more convincing proof that the concepts and explanations they propose can apply to other societies and to IR more generally. Moreover, there is the need for these approaches to attract a critical mass of followers worldwide, stimulate a research agenda for other, especially younger scholars, and distance themselves from the official Chinese policy framings. The Global IR approach offers a helpful framework for highlighting and perhaps addressing these challenges, especially in avoiding cultural exceptionalism and ensuring their wider relevance beyond China.

description: Oxide heterointerfaces constitute a rich platform for realizing novel functionalities in condensed matter. A key aspect is the strong link between structural and electronic properties, which can be modified by interfacing materials with distinct lattice symmetries. Here we determine the effect of the cubic-tetragonal distortion of $\text{SrTiO}_3$ on the electronic properties of thin films of $\text{SrIrO}_3$, a topological crystalline metal hosting a delicate interplay between spin-orbit coupling and electronic correlations. We demonstrate that below the transition temperature at 105 K, $\text{SrIrO}_3$ orthorhombic domains couple directly to tetragonal domains in $\text{SrTiO}_3$. This forces the in-phase rotational axis to lie in-plane and creates a binary domain structure in the $\text{SrIrO}_3$ film. The close proximity to the metal-insulator transition in ultrathin $\text{SrIrO}_3$ causes the individual domains to have strongly anisotropic transport properties, driven by a reduction of bandwidth along the in-phase axis. The strong structure-property relationships in perovskites make these compounds particularly suitable for static and dynamic coupling at interfaces, providing a promising route towards realizing novel functionalities in oxide heterostructures.

description: The discipline of International Relations (IR) is increasingly being criticized for ignoring and marginalizing states and societies outside of the core countries of the West. The idea of a 'Global IR' has been proposed since 2014 a pathway toward a bridging the 'West and the Rest' divide and thus develop a more inclusive discipline, recognizing its multiple and diverse foundations. At the same time, there is a trend toward developing theories, or 'schools', on a national or regional basis, the leading examples of which come from China. This article examines some theoretical constructs emerging in China, such as the 'Relational Theory' of Qin Yaqing, who is the foundational scholar in the 'Chinese School of IR', the Tianxia ('all under Heaven') concept as applied to IR and world order by Zhao Tingyang, and 'Moral Realism' of Yan Xuetong, who is the leading figure of the 'Tsinghua School'. To many scholars, both inside and outside China, the relationship among the various Chinese approaches and their overall contribution to the IR field remain unclear. Without claiming to capture all their nuances and complexity, this article hopes to stimulate a conversation among scholars, Chinese and foreign, with a view to generate greater clarity and highlight their importance to the study of IR. I argue that while making important contributions, the Chinese approaches to International Relations Theory (IRT) also face a number of challenges. This includes the need for them to offer more convincing proof that the concepts and explanations they propose can apply to other societies and to IR more generally. Moreover, there is the need for these approaches to attract a critical mass of followers worldwide, stimulate a research agenda for other, especially younger scholars, and distance themselves from the official Chinese policy framings. The Global IR approach offers a helpful framework for highlighting and perhaps addressing these challenges, especially in avoiding cultural exceptionalism and ensuring their wider relevance beyond China.
A remarkably narrow RHESSI x-ray flare on 2011 September 25

description: The unusually narrow X-ray source imaged with the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) during an impulsive spike lasting for ∼10 s during the Geostationary Operational Environmental Satellite C7.9 flare on 2011 September 25 (SOL2011-09-25T03:32) was only ∼2″ wide and ∼10″ long. Comparison with Helioseismsic and Magnetic Imager magnetograms and Atmospheric Imaging Assembly images at 1700 Å shows that the X-ray emission was primarily from a long ribbon in the region of positive polarity with little if any emission from the negative polarity ribbon. However, a thermal plasma source density of ∼1012 cm-3 estimated from the RHESSI-derived emission measure and source area showed that this could best be interpreted as a coronal hard X-ray source in which the accelerated electrons with energies less than ∼50 keV were stopped by Coulomb collisions in the corona, thus explaining the lack of the more usual bright X-ray footpoints. Analysis of RHESSI spectra shows greater consistency with a multi-temperature distribution and a low-energy cutoff to the accelerated electron spectrum of 22 keV compared to 12 keV if a single-temperature distribution is assumed. This leads to a change in the lower limit on the total energy in electrons by an order of magnitude, given the steepness of the best-fit electron spectrum with a power-law index of ∼6.

description: Die Arbeit bietet einen Überblick über Uwe Kolbes lyrisches Werk bis 2013, wobei drei Hauptaspekte hervorgehoben werden. Erstens, Kolbes persönliche und politische Auseinandersetzung mit der DDR, einschließlich seiner Erfahrungen mit den gesellschaftlichen und politischen Bedingungen sowie dem Ost-West-Konflikt und der Literaturszene im Prenzlauer Berg. Zweitens, seine Reise- und Zeitreise-Gedichte ab Mitte der 1980er Jahre, die eine individuelle und kompensatorische Erkundung einer 'neuen', 'weiteren' Welt darstellen. Drittens, die spielerische Aufnahme der griechisch-römischen Antike in seinem Werk, die einen markanten Kontrast zu den anderen Themen bildet.

On The Ladder Bethe-Salpeter Equation
Creators: name: Efimov, G. V.
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The Bethe-Salpeter (BS) equation in the ladder approximation is studied within a scalar theory: two scalar fields (constituents) with mass $m$ interacting via an exchange of a scalar field (tieon) with mass $μ$. The BS equation is written in the form of an integral equation in the configuration Euclidean $x$-space with the kernel which for stable bound states $M<2m$ is a self-adjoint positive operator. The solution of the BS equation is formulated as a variational problem. The nonrelativistic limit of the BS equation is considered. The role of so-called abnormal states is discussed. The analytical form of test functions for which the accuracy of calculations of bound state masses is better than 1% (the comparison with available numerical calculations is done) is determined. These test functions make it possible to calculate analytically vertex functions describing the interaction of bound states with constituents. As a by-product a simple solution of the Wick-Cutkosky model for the case of massless bound states is demonstrated.

subject: 491.8

description: Der Text analysiert die Tradition der deutschen weltanschaulichen Lyrik, insbesondere in Goethes Spätwerk, und deren Einfluss auf Enzensberger. Enzensberger verbindet Naturdidaktik, die in Goethes Werken wie "Parabase" und "Eins und alles" zum Ausdruck kommt, mit einer sozialkritischen Didaktik, die an Brecht erinnert. Sein Werk zeichnet sich durch eine naturwissenschaftliche Perspektive, gemäßigten Moralskeptizismus und einen reflektierten "Altersstil" aus, was Sentimentalität und Pathos vermeidet. In Gedichtsammlungen wie "Zukunftsmusik" und "Kiosk" findet sich eine Atmosphäre der "zarten Apokalypse", geprägt von sachlicher Didaktik, Ironie und Skepsis. Enzensberger betrachtet den Mauerfall als ein kleines Ereignis in der deutschen Nachkriegsgeschichte, symptomatisch für die von ihm kritisierte Moderne. Er konzentriert sich auf die Darstellung des Lebens in seiner Vielfalt und Widerstandsfähigkeit, wobei er alltägliche Themen und Menschen mit systematischer Leidenschaft und als Kuriositätensammler untersucht.

description: Context. As a fragile element, lithium is a sensitive probe of physical processes occurring in stellar interiors. Aims. We aim at investigating the relationship between lithium abundance and rotation rate in low-mass members of the newly discovered 125~Myr-old Psc-Eri stellar stream. Methods. We obtained high resolution optical spectra and measure the equivalent width of the 607.8 nm LiI line for 40 members of the Psc-Eri stream, whose rotational periods have been derived by arXiv:1905.10588. Results. We show that a tight correlation exists between lithium content and rotation rate among the late-G to early K-type stars of the Psc-Eri stream. Fast rotators are systematically Li-rich, while slow rotators are Li-depleted. This trend mimics the one previously reported for the similar age Pleiades cluster. Conclusions. The lithium-rotation connection thus seems to be universal over a restricted effective temperature range for low-mass stars at or close to the zero-age main sequence, and does not depend on environmental conditions.
