description: We study the evolution of the observed photospheric magnetic field and the modeled global coronal magnetic field during the past 3 1/2 solar activity cycles observed since the mid-1970s. We use synoptic magnetograms and extrapolated potential-field models based on longitudinal full-disk photospheric magnetograms from the NSO's three magnetographs at Kitt Peak, the Synoptic Optical Long-term Investigations of the Sun (SOLIS) vector spectro-magnetograph (VSM), the spectro-magnetograph and the 512-channel magnetograph instruments, and from the U. Stanford's Wilcox Solar Observatory. The associated multipole field components are used to study the dominant length scales and symmetries of the coronal field. Polar field changes are found to be well correlated with active fields over most of the period studied, except between 2003-6 when the active fields did not produce significant polar field changes. Of the axisymmetric multipoles, only the dipole and octupole follow the poles whereas the higher orders follow the activity cycle. All non-axisymmetric multipole strengths are well correlated with the activity cycle. The tilt of the solar dipole is therefore almost entirely due to active-region fields. The axial dipole and octupole are the largest contributors to the global field except while the polar fields are reversing. This influence of the polar fields extends to modulating eruption rates. According to the Computer Aided CME Tracking (CACTus), Solar Eruptive Event Detection System (SEEDS), and Nobeyama radioheliograph prominence eruption catalogs, the rate of solar eruptions is found to be systematically higher for active years between 2003-2012 than for those between 1997-2002. This behavior appears to be connected with the weakness of the late-cycle 23 polar fields as suggested by Luhmann. We see evidence that the process of cycle 24 field reversal is well advanced at both poles.

description: Recently, three reactor neutrino experiments, Daya Bay, Double Chooz and RENO have directly measured the neutrino mixing angle $θ_{13}$. In this paper, another important oscillation parameter, effective $Δm_{31}^2$ (= $Δ\tilde{m}_{31}^2$) is measured using baseline dependence of the reactor neutrino disappearance. A global fit is applied to publicly available data and $Δ\tilde{m}_{31}^2 = 2.95^{+0.42}_{-0.61} \times 10^{-3}$ eV$^2$, $\sin^22θ_{13} = 0.099^{+0.016}_{-0.012}$ are obtained by setting both parameters free. This result is complementary to $Δtilde{m}_{31}^2$ to be measured by spectrum shape analysis. The measured $Δ\tilde{m}_{31}^2$ is consistent with $Δ\tilde{m}_{32}^2$ measured by $ν_μ$ disappearance in MINOS, T2K and atmospheric neutrino experiments within errors. The minimum $χ^2$ is small, which means the results from the three reactor neutrino experiments are consistent with each other.

A counterexample to a geometric Hales-Jewett type conjecture
Creators: name: Gruslys, Vytautas

description: Pór and Wood conjectured that for all \(k,l \ge 2\) there exists \(n \ge 2\) with the following property: whenever \(n\) points, no \(l + 1\) of which are collinear, are chosen in the plane and each of them is assigned one of \(k\) colours, then there must be a line (that is, a maximal set of collinear points) all of whose points have the same colour. The conjecture is easily seen to be true for \(l = 2\) (by the pigeonhole principle) and in the case \(k = 2\) it is an immediate corollary of the Motzkin-Rabin theorem. In this note we show that the conjecture is false for \(k, l \ge 3\).

description: Basierend auf den empirischen Befunden der aktuellen Studie sowie im Rückblick auf die drei vorherigen Erhebungen (2007; 2012; 2017) gibt der Bericht Auskunft über die Stellenstruktur, die Zusammensetzung der Professorien und des akademischen Mittelbaus sowie die Entwicklung der Qualifikationsarbeiten und anstehende Emeritierungen an den Fakultäten und nichtfakultären Einrichtungen für Katholische Theologie im deutschsprachigen Raum. Die Zahl der Professuren ist erstaunlich konstant, zum Mittelbau zählen heute 50 % Personen mehr als noch 2011. Dramatisch erscheint dagegen zum einen der in der Katholischen Theologie auffallend ausgeprägte gender gap – festzumachen u. a. an einer deutlich niedrigeren Abschlussquote bei Promovendinnen (31 % statt 52 %) und Habilitandinnen (37 % statt 67 %) sowie an einem besonders niedrigen Frauenanteil in den Professorien (19 %). Zum anderen ist mit Blick auf den voraussichtlichen Anstieg bei den neu zu besetzenden Professuren eine dramatische Zuspitzung des Nachwuchsmangels in der Katholischen Theologie zu prognostizieren.

Chiral Y-junction of Luttinger liquid wires at strong coupling: fermionic representation

description: We calculate the conductances of a three-terminal junction set-up of spinless Luttinger liquid wires threaded by a magnetic flux, allowing for different interaction strength g_3 != g in the third wire. We employ the fermionic representation in the scattering state picture, allowing for a direct calculation of the linear response conductances, without the need of introducing contact resistances at the connection points to the outer ideal leads. The matrix of conductances is parametrized by three variables. For these we derive coupled renormalization group (RG) equations, by summing up infinite classes of contributions in perturbation theory. The resulting general structure of the RG equations may be employed to describe junctions with an arbitrary number of wires and arbitrary interaction strength in each wire. The fixed point structure of these equations (for the chiral Y-junction) is analyzed in detail. For repulsive interaction (g,g_3>0) there is only one stable fixed point, corresponding to the complete separation of the wires. For attractive interaction (g<0 and/or g_3<0) four fixed points are found, the stability of which depends on the interaction strength. We confirm our previous weak-coupling result of lines of fixed points for special values of the interaction parameters reaching into the strong coupling domain. We find new fixed points not discussed before, even at the symmetric line g=g_3, at variance with the results of Oshikawa et al. The pair tunneling phenomenon conjectured by the latter authors is not found by us.

Steinitz theorems for simple orthogonal polyhedra

Publisher: name: Journal of Computational Geometry
Year: 2014

description: We define a simple orthogonal polyhedron to be a three-dimensional polyhedron with the topology of a sphere in which three mutually-perpendicular edges meet at each vertex.By analogy to Steinitz's theorem characterizing the graphs of convex polyhedra, we find graph-theoretic characterizations of three classes of simple orthogonal polyhedra: corner polyhedra, which can be drawn by isometric projection in the plane with only one hidden vertex, xyz polyhedra, in which each axis-parallel line through a vertex contains exactly one other vertex, and arbitrary simple orthogonal polyhedra. In particular, the graphs of xyz polyhedra are exactly the bipartite cubic polyhedral graphs, and every bipartite cubic polyhedral graph with a 4-connected dual graph is the graph of a corner polyhedron. Based on our characterizations we find efficient algorithms for constructing orthogonal polyhedra from their graphs.

Non-relativistic radiation mediated shock breakouts: III. Spectral properties of SN shock breakout

description: The spectrum of radiation emitted following shock breakout from a star's surface with a power-law density profile $ρ\propto x^n$ is investigated. Assuming planar geometry, local Compton equilibrium and bremsstrahlung emission as the dominant photon production mechanism, numerical solutions are obtained for the photon number density and temperature profiles as a function of time, for hydrogen-helium envelopes. The temperature solutions are determined by the breakout shock velocity $v_0$ and the pre-shock breakout density $ρ_0$, and depend weakly on the value of n. Fitting formulas for the peak surface temperature at breakout as a function of $v_0$ and $ρ_0$ are provided, with $T_{peak}\approx 9.44\exp{[12.63(v_0/c)^{1/2}]}$ eV, and the time dependence of the surface temperature is tabulated. The time integrated emitted spectrum is a robust prediction of the model, determined by $\mathcal{T}_{\rm peak}$ and $v_0$ alone and insensitive to details of light travel time or slight deviations from spherical symmetry. Adopting commonly assumed progenitor parameters, breakout luminosities of ~10^45 erg/s and ~10^44 erg/s in the 0.3-10 keV band are expected for BSG and RSG/He-WR progenitors respectively (T_{peak} is well below the band for RSGs, unless their radius is ~10^13 cm). >30 detections of SN1987A-like (BSG) breakouts are expected over the lifetime of ROSAT and XMM-Newton. An absence of such detections would imply that either the typical parameters assumed for BSG progenitors are grossly incorrect or that their envelopes are not hydrostatic. The observed spectrum and duration of XRF 080109/SN2008D are in tension with a non-relativistic breakout from a stellar surface interpretation.

description: Can folding a piece of paper flat make it larger? We explore whether a shape S must be scaled to cover a flat-folded copy of itself. We consider both single folds and arbitrary folds (continuous piecewise isometries \(S\to\mathbb{R}^2\)). The underlying problem is motivated by computational origami, and is related to other covering and fixturing problems, such as Lebesgue's universal cover problem and force closure grasps. In addition to considering special shapes (squares, equilateral triangles, polygons and disks), we give upper and lower bounds on scale factors for single folds of convex objects and arbitrary folds of simply connected objects.

description: This paper characterizes Goppa codes of certain maximal curves over finite fields defined by equations of the form $y^n = x^m + x$. We investigate Algebraic Geometric and quantum stabilizer codes associated with these maximal curves and propose modifications to improve their parameters. The theoretical analysis is complemented by extensive simulation results, which validate the performance of these codes under various error rates. We provide concrete examples of the constructed codes, comparing them with known results to highlight their strengths and trade-offs. The simulation data, presented through detailed graphs and tables, offers insights into the practical behavior of these codes in noisy environments. Our findings demonstrate that while the constructed codes may not always achieve optimal minimum distances, they offer systematic construction methods and interesting parameter trade-offs that could be valuable in specific applications or for further theoretical study.

description: We present the results of a recent novel application of the `hard exclusive' perturbative formalism to the process gg --> MMbar at large angles, where M (Mbar) is a light meson (anti-meson). As well as discussing the important theoretical features of the relevant leading-order gg --> qqbar(gg) qqbar(gg) 6-parton amplitudes, we also comment on their phenomenological implications. In particular, we consider the central exclusive production of meson pairs at comparatively large transverse momentum k_t, which is expected to proceed via this mechanism. We show that this leads to various non-trivial predictions for a range of exclusive processes, and that the cross sections for the eta' and eta mesons display significant sensitivity to any valence gg component of the meson wavefunctions.

Partial covering of a circle by equal circles. Part II: The case of 5 circles

description: How must n equal circles of given radius r be placed so that they cover as great a part of the area of the unit circle as possible? In this Part II of a two-part paper, a conjectured solution of this problem for n = 5 is given for r varying from the maximum packing radius to the minimum covering radius. Results are obtained by applying a mechanical model described in Part I. A generalized tensegrity structure is associated with a maximum area configuration of the 5 circles, and by using catastrophe theory, it is pointed out that the ''equilibrium paths'' have bifurcations, that is, at certain values of r, the type of the tensegrity structure and so the type of the circle configuration changes.

description: The high incidence of tuberculosis, the increase in the number of multidrug-resistant cases and the combined pathology with HIV infection dictate the need to search for new targets for the development of modern diagnostic tests, vaccines and treatment methods for tuberculosis. Immune cells produce cytokines when recognizing fragments of mycobacteria. Functional differences in cytokine synthesis are a factor in the immune system dysregulation, which can lead to the development of the disease. The review presents current data about the main cytokines involved in the immunopathogenesis of tuberculosis infection, assessed their impact on the course and development of the disease, presents data on the association of cytokine gene polymorphisms with tuberculosis. Key words: cytokines, tuberculosis, innate immunity, Mycobacterium tuberculosis, INF, TNF-α, IL-6, IL-10, IL-12.

description: How must n equal circles of given radius be placed so that they cover as great a part of the area of the unit circle as possible? To analyse this mathematical problem, mechanical models are introduced. A generalized tensegrity structure is associated with a maximum area configuration of the n circles, whose equilibrium configuration is determined numerically with the method of dynamic relaxation, and the stability of equilibrium is investigated by means of the stiffness matrix of the tensegrity structure. In this Part I, the principles of the models are presented, while an application will be shown in the forthcoming Part II.

description: Let S be a set of n points in Rd. A Steiner convex partition is a tiling of conv(S) with empty convex bodies. For every integer d, we show that S admits a Steiner convex partition with at most ⌈(n-1)/d⌉ tiles. This bound is the best possible for points in general position in the plane, and it is the best possible apart from constant factors in every fixed dimension d≥3. We also give the first constant-factor approximation algorithm for computing a minimum Steiner convex partition of a planar point set in general position. Establishing a tight lower bound for the maximum volume of a tile in a Steiner convex partition of any n points in the unit cube is equivalent to a famous problem of Danzer and Rogers. It is conjectured that the volume of the largest tile is ω(1/n). Here we give a (1-\epsilon)-approximation algorithm for computing the maximum volume of an empty convex body amidst n given points in the d-dimensional unit box [0,1]d.

Der franziskanische Ansatz zur Wirtschaftsethik: Eine neue sozio-ökonomische Ordnung aus dem Geist der Armutsbewegung
Creators: name: Franco, Giuseppe
Publisher: name: Jahrbuch für Christliche Sozialwissenschaften
Year: 2022

description: Der Beitrag widmet sich dem franziskanischen Ansatz zur Wirtschaftsethik im Spätmittelalter. Franziskanische Theologen trugen zum wirtschaftlichen Diskurs bei: Sie lebten in einer Gesellschaft, die durch eine kommerzielle Revolution und eine zunehmende internationale Finanzaktivität geprägt war; sie legitimierten auf der Grundlage eines theologischen Verständnisses der Armut und einer profunden Kenntnis der wirtschaftlichen Mechanismen die moralische Dimension des Marktes und die gesellschaftliche Rolle der Kaufleute; sie rechtfertigten außerdem eine bestimmte Verwendung des Geldes, die auf Produktivität ausgerichtet sein und der Gesellschaft dienen sollte. Das Hauptinteresse der franziskanischen Theologen galt jedoch nicht der Analyse wirtschaftlicher Gesetze, sondern den moralischen Implikationen ökonomischen Handelns, weshalb sie wirtschaftliche Fragen in einen normativen, sozialen und religiösen Kontext stellten. Die interdisziplinäre Struktur des franziskanischen Ansatzes bei wirtschaftlichen Fragen kann den heutigen Diskurs über die theoretischen und normativen Grundlagen der Wirtschaftsethik bereichern. Sich auf die franziskanische Tradition zurückzubesinnen, ist nicht vormodern, sondern aus ihr kann man lernen, dass in Zeiten der Globalisierung auch funktional ausdifferenzierte Gesellschaften normativen Kriterien unterworfen werden sollten, dass wirtschaftliche Prozesse und die Gestaltung einer menschenwürdigen Wirtschafts- und Gesellschaftsordnung an sozialen Zielen auszurichten sind und dass die Freiheit des Einzelnen von der Solidarität aller in einer sozial gerechten Gesellschaft abhängt.

description: In recent work we have developed a new unfolding method for computing one-loop modular integrals in string theory involving the Narain partition function and, possibly, a weak almost holomorphic elliptic genus. Unlike the traditional approach, the Narain lattice does not play any role in the unfolding procedure, T-duality is kept manifest at all steps, a choice of Weyl chamber is not required and the analytic structure of the amplitude is transparent. In the present paper, we generalise this procedure to the case of Abelian Z_N orbifolds, where the integrand decomposes into a sum of orbifold blocks that can be organised into orbits of the Hecke congruence subgroup Γ_0(N). As a result, the original modular integral reduces to an integral over the fundamental domain of Γ_0(N), which we then evaluate by extending our previous techniques. Our method is applicable, for instance, to the evaluation of one-loop corrections to BPS-saturated couplings in the low energy effective action of closed string models, of quantum corrections to the Kähler metric and, in principle, of the free-energy of superstring vacua.

description: For \(k\ge 3\), a \(k\)-angulation is a 2-connected plane graph in which every internal face is a \(k\)-gon. We say that a point set \(P\) admits a plane graph \(G\) if there is a straight-line drawing of \(G\) that maps \(V(G)\) onto \(P\) and has the same facial cycles and outer face as \(G\). We investigate the conditions under which a point set \(P\) admits a \(k\)-angulation and find that, for sets containing at least \(2k^2\) points, the only obstructions are those that follow from Euler's formula.

description: Der Beitrag zeigt Theologische Sozialethik im Spannungsfeld von kognitiven und normativen Geltungsansprüchen, die teils universalistischer, teils partikularer Art sind. Er artikuliert Skepsis gegen die Vorstellung, dass das Fach normative Kriterien und Prinzipien in eine empirisch-sozialwissenschaftliche Deskription gesellschaftlicher Verhältnisse einträgt. Vielmehr plädiert er dafür, der interdisziplinär zu betreibenden Gesellschaftstheorie zuzutrauen, Normativität zu erschließen. Als Konsequenz ist Theologische Sozialethik sozialwissenschaftlicher auszurichten. Verbessern kann sie nicht die Gesellschaft, aber ihre eigene Theoriearbeit. Hinsichtlich der Praxisbedeutsamkeit bleiben die wissenschaftlichen Reflexionen nicht nur in normativer Hinsicht gegenüber praktischen Diskursen in der Gesellschaft vorläufig; auch die Relevanz der Sozialanalyse hängt davon ab, dass sich gesellschaftliche Akteure in ihrer Lebenslage darin wiedererkennen und sie ihnen hilfreiches Mittel für die Reflexion und Bestimmung ihrer politischen Praxis ist.

Publisher: name: Astrakhan State Medical University
Year: 2019

description: Microbiological research on tuberculosis is a complex and strictly regulated process, the main purpose of which is the isolation and identification of mycobacteria of the tuberculosis complex. This process involves the use of a specific list of culture media, as well as the process of decontamination, aimed at suppressing the growth of concomitant bacterial microflora.The use of additional culture media for primary inoculation during the study for tuberculosis allows one to isolate not only classical “contaminants” from the clinical material, but also microflora, which has clinical significance in certain groups of patients.The results obtained in the study allow us to conclude that representatives of acid-resistant actinomycetes stand out in the structure of the contaminating microflora that grew on liquid media much more often. Among which were isolated non-tuberculous mycobacteria with atypical cultural properties, as well as representatives of the genera Nocardia spp., Gordonia spp., Rhodococcus spp., Tsukamurella spp. Key words: contaminating microflora, decontamination, non-tuberculous mycobacteria, micromycetes, saprophytic microflora, nocradia, gordonia.

description: Der Beitrag geht davon aus, dass die vielen unterschiedlichen Selbstverständnisse der Disziplin Christliche Sozialethik ein wissenschaftssystematisches Problem darstellen. Das kann beispielsweise dazu führen, dass diese mangelnde disziplinäre Identität die Stellung der Disziplin im Fächerkanon der (katholischen) Theologie schwächt. Der Beitrag argumentiert für eine systematische Verbindung der verschiedenen Bezugswissenschaften und Methoden der Christlichen Sozialethik. Diese Verbindung gewährleisten soll der philosophische Pragmatismus als integrierendes Element. Der Text zeigt dies an der Soziologie bzw. Sozialtheorie als Bezugswissenschaft der Christlichen Sozialethik. Aus den Grundorientierungen einer pragmatistisch orientierten Soziologie oder Sozialtheorie, etwa ihrer spezifischen Handlungstheorie oder dem Selbstverständnis als engagierte Soziologie, gewinnt die Christliche Sozialethik eine spezifische Gestalt um den Begriff des Primats der Praxis herum, der auch Türen für eine theologische Grundlegung des Faches öffnen kann.

description: A polygon \(Q\) is a \(k\)-bounded Hausdorff Core of a polygon \(P\) if \(P\) contains \(Q\), \(Q\) is convex, and the Hausdorff distance between \(P\) and \(Q\) is at most \(k\). A Hausdorff Core of \(P\) is a \(k\)-bounded Hausdorff Core of \(P\) with the minimum possible value of \(k\), which we denote \(k_{\min}\). Given any \(k\) and any \(\varepsilon\gt 0\), we describe an algorithm for computing a \(k'\)-bounded Hausdorff Core (if one exists) in \(O(n^3+n^2\varepsilon^{-4}(\log n+ \varepsilon^{-2}))\) time, where \(k'\lt k+d_{\text{rad}}\cdot\varepsilon\) and \(d_{\text{rad}}\) is the radius of the smallest disc that encloses \(P\) and whose center is in \(P\). We use this solution to provide an approximation algorithm for the optimization Hausdorff Core problem which results in a solution of size \(k_{\min}+d_{\text{rad}}\cdot\varepsilon\) in \(O(\log(\varepsilon^{-1})(n^3+n^2\varepsilon^{-4}(\log n+ \varepsilon^{-2})))\) time. Finally, we describe an approximation scheme for the \(k\)-bounded Hausdorff Core problem which, given a polygon \(P\), a distance \(k\), and any \(\varepsilon\gt 0\), answers true if there is a \(((1+\varepsilon)k)\)-bounded Hausdorff Core and false if there is no \(k\)-bounded Hausdorff Core. The running time of the approximation scheme is in \(O(n^3+n^2\varepsilon^{-4}(\log n+ \varepsilon^{-2}))\).

description: Ausgehend von Korffs Überlegungen zur Gliederung des materialen ethischen Felds wird in einem explorativen Zugang Latours assoziationssoziologischer Ansatz daraufhin diskutiert, wie die Sozialethik den Sozial- und den Umweltbezug stärker miteinander verwoben denken könnte, etwa in der Form einer Geo-Sozialethik. Mit Blick auf die aktuelle Zeitdiagnose Anthropozän wird die Reflexion dieses Verhältnisses um den Aspekt des Geschichtlichen erweitert. Als Ergebnis zeigt sich, dass eine der großen Aufgaben der Sozialethik darin liegen kann, die schöpfungstheologischen und heilsgeschichtlichen Traditionslinien empirisch fundiert zusammenzuführen, um zu klären, wie die Erde allen ein gemeinsames Lebenshaus sein kann.

description: This paper presents numerical simulations of dual-frequency second-order ultrasound field (SURF) reverberation suppression transmit-pulse complexes. Such propagation was previously studied in a homogeneous medium. Here instead the propagation path includes a strongly aberrating body-wall modeled by a sequence of delay-screens. The applied SURF transmit pulse complexes each consist of a high-frequency imaging 3.5 MHz pulse combined with a low-frequency 0.5 MHz sound speed manipulation pulse. Furthermore, the feasibility of two signal post-processing methods are investigated using the aberrated transmit SURF beams. These methods are previously shown to adjust the depth of maximum SURF reverberation suppression within a homogeneous medium. The request of the study arises because imaging situations where reverberation suppression is useful are also likely to produce pulse wave-front distortion (aberration). Such distortions could potentially produce time-delays that cancel the accumulated propagation time-delay needed for the SURF reverberation suppression technique. Results show that both the generation of synthetic SURF reverberation suppression imaging transmit-beams, and the following post-processing adjustments, are attainable even when a body-wall introduces time-delays which are larger than previously reported delays measured on human body-wall specimens.

Abschied vom Container. Zur Einordnung eines relationalen Wirklichkeitsverständnisses

description: Bruno Latour ist ein wichtiger Referenzautor, wenn es um die Relationierung (In-Beziehung-Setzen) menschlicher Existenz und die Relativierung von anthropozentrischen Sichtweisen geht. Er selbst legt wenig Wert darauf, seine Annahmen und Analysen im Dialog mit anderen sozialphilosophischen und soziologischen Theorien zu entwickeln. Um daraus sich ergebende Verständnishindernisse abzubauen, wird in einem ersten Schritt Latours relationaler Ansatz in einen ideengeschichtlichen Kontext gestellt. In einem zweiten Schritt wird der analysierte Übergang zu einem relationalen Ansatz als Wandel der räumlichen Leitfigur gedeutet. Das Bild streng abgrenzbarer sozialer Container-Räume, die von einer zentralen Instanz überschaut, kontrolliert und gesteuert werden, wird demnach abgelöst von einem relationalen Raummodell. In einem letzten Schritt wird vorgeschlagen, die Ökologie – als Wissenschaft der verwobenen Lebensnetze und Ökosysteme – zur Leitwissenschaft für sozialwissenschaftliches Denken zu erheben. Damit ist nicht nur gemeint, die Verwobenheit von Natur und Kultur/Gesellschaft in den Blick zu nehmen bzw. deren Trennung zu überwinden. In allgemeiner sozialtheoretischer Perspektive geht es, so die These, um ein relationales Denken, um eine Ökologie der Beziehungen. Die Einsicht, dass der Mensch in soziale und systemische Kontexte verwoben und von diesen abhängig ist, wird ausgeweitet auf alles Leben. Alles ist demnach miteinander vernetzt, verknüpft, vermischt und vermengt.

description: In Auseinandersetzung mit Bruno Latour, vor allem seinen wissenschaftstheoretischen Überlegungen, der Kritik an den Dichotomien der Moderne und dem Umgang mit Hybridität wird ein Modell von Christlicher Sozialethik als veränderungsorientierter Wissenschaft entwickelt. Ihre Aufgabe besteht darin, eine (neue) Beziehung zur Erde herzustellen, damit wir wahrnehmen, wer mit uns den Grund teilt, auf dem und von dem wir leben. Dieses Kollektiv der Menschen und Nicht-Menschen gilt es zur gemeinsamen Welt zu versammeln, um zu verhandeln, wie wir miteinander leben wollen.

description: Four-spin exchange interaction has been raising intriguing questions regarding the exotic phase transitions it induces in two-dimensional quantum spin systems. In this context, we investigate the effects of a cyclic four-spin exchange in the quasi-1D limit by considering a general N-leg spin ladder. We show by means of a low-energy approach that, depending on its sign, this ring exchange interaction can engender either a staggered or a uniform dimerization from the conventional phases of spin ladders. The resulting quantum phase transition is found to be described by the SU(2)_N conformal field theory. This result, as well as the fractional value of the central charge at the transition, is further confirmed by a large-scale numerical study performed by means of Exact Diagonalization and Density Matrix Renormalization Group approaches for N \le 4.

description: We prove that for any point set P in the plane, a triangle T, and a positive integer k, there exists a coloring of P with k colors such that any homothetic copy of T containing at least 144k8 points of P contains at least one of each color. This is the first polynomial bound for range spaces induced by homothetic polygons.The only previously known bound for this problem applies to the more general case of octants in ℝ3, but is doubly exponential.

description: Light new particles with masses below 10 keV, often considered as a plausible extension of the Standard Model, will be emitted from the solar interior, and can be detected on the Earth with a variety of experimental tools. Here we analyze the new "dark" vector state V, a massive vector boson mixed with the photon via an angle kappa, that in the limit of the small mass m_V has its emission spectrum strongly peaked at low energies. Thus, we utilize the constraints on the atomic ionization rate imposed by the results of the XENON10 experiment to set the limit on the parameters of this model: kappa times m_V< 3 times10^{-12} eV. This makes low-threshold Dark Matter experiments the most sensitive dark vector helioscopes, as our result not only improves current experimental bounds from other searches by several orders of magnitude, but also surpasses even the most stringent astrophysical and cosmological limits in a seven-decade-wide interval of m_V. We generalize this approach to other light exotic particles, and set the most stringent direct constraints on "mini-charged" particles.

Prophetische Intervention als Konflikteskalation

Publisher: name: Jahrbuch für Christliche Sozialwissenschaften

description: Im Umgang mit sozialen Konflikten wird aus religiöser Sicht häufig der Aspekt der Versöhnung im Sinne einer harmonischen Überwindung von Gegensätzen in den Vordergrund gestellt. Konfliktsoziologische Forschungen im Anschluss an Georg Simmel legen allerdings einen Fokus auf die positive Kraft des Konflikts selbst nahe. Vor diesem Hintergrund fokussiert sich der Beitrag auf Dynamiken der Konflikteskalation und bringt diese anhand des biblischen Hoseabuchs mit prophetischer Intervention in Verbindung. Anstatt Konfliktgegenstände auszublenden, geht es darum, Konflikte durch eskalierende Maßnahmen zu steigern. Angesichts der Ambivalenz von Eskalation werden Kriterien herausgearbeitet, die eine produktive Entwicklung von Konflikten gewährleisten können. Eine konflikttheoretisch grundierte Lektüre von Hoseatexten zeigt auf, wie auch dort Momente der Eskalation den Umgang mit sozialen, ethischen und die Gottesbeziehung betreffenden Konflikten prägen. Mit Hilfe einer öffentlichen Konflikttheologie werden schließlich die beiden Perspektiven zusammengeführt. Auf diese Weise fungiert theologische Sozialethik als diskursiver Ort an den Kontaktzonen zwischen Theologie und Sozialwissenschaften. Hosea gibt so den Anstoß, verschiedene Konfliktdimensionen in der Gesellschaft im Licht der Beziehung zwischen Gott und Menschen zu deuten. Dabei leistet gerade die daran ersichtliche innere Konfliktstruktur von Religion einen Beitrag dazu, Konflikte nicht zu negieren, sondern konstruktiv zu bearbeiten.

Fat polygonal partitions with applications to visualization and embeddings

description: Let T be a rooted and weighted tree, where the weight of any node is equal to the sum of the weights of its children. The popular Treemap algorithm visualizes such a tree as a hierarchical partition of a square into rectangles, where the area of the rectangle corresponding to any node in T is equal to the weight of that node. The aspect ratio of the rectangles in such a rectangular partition necessarily depends on the weights and can become arbitrarily high. We introduce a new hierarchical partition scheme, called a polygonal partition, which uses convex polygons rather than just rectangles. We present two methods for constructing polygonal partitions, both having guarantees on the worst-case aspect ratio of the constructed polygons; in particular, both methods guarantee a bound on the aspect ratio that is independent of the weights of the nodes. We also consider rectangular partitions with slack, where the areas of the rectangles may differ slightly from the weights of the corresponding nodes. We show that this makes it possible to obtain partitions with constant aspect ratio. This result generalizes to hyper-rectangular partitions in ℝd. We use these partitions with slack for embedding ultrametrics into d-dimensional Euclidean space: we give a polylog(Δ)-approximation algorithm for embedding n-point ultrametrics into ℝd with minimum distortion, where Δ denotes the spread of the metric. The previously best-known approximation ratio for this problem was polynomial in n. This is the first algorithm for embedding a non-trivial family of weighted-graph metrics into a space of constant dimension that achieves polylogarithmic approximation ratio.

Theologie der Sozialethik im Blick auf die Praxis gelebter Freiheit
Creators: name: Vogt, Markus

description: Im Schatten des Natur- und Vernunftrechts sowie des menschenrechtlichen Ansatzes gibt es in der Sozialethik eine starke Tradition der Abstinenz von explizit theologischen Argumenten. Demgegenüber wird methodisch eine Zweisprachigkeit hinsichtlich der Verknüpfung theologischer und säkularer Sprachformen gefordert. Diese dient nicht nur der Verständlichkeit nach außen, sondern auch der human- und sozialwissenschaftlichen Überprüfung und Konkretion theologischer Normen. Der christliche Glaube wird also nicht als irrationaler Antagonist des Wissens verstanden, sondern als ethisch relevante, kritisierende, motivierende und integrierende Sinnperspektive und wissensermöglichende Lebensform. Das Theologische der Sozialethik ist nicht als alternative Begründung zu verstehen, sondern ergibt sich aus der Reflexion der Praxis gelebter Freiheit. Die Tradition des Humanismus im Schnittfeld zwischen Theologie und philosophischer Anthropologie kann dabei helfen, in neuer Weise die Relevanz der befreienden Dimension des christlichen Glaubens und seine Ausrichtung auf gelingendes Menschsein zu entdecken. Dabei bringt die Kontingenz und Selbstgefährdung des Projekts der Moderne eine neue Dringlichkeit der Vergewisserung hinsichtlich seiner normativen und theologischen Grundlagen jenseits einer Erfüllung im Diesseits hervor. In diesem Suchprozess erweist sich Christliche Sozialethik als eine originäre Form der Gottesrede.
