description: We theoretically investigate the ground state properties of ferromagnetic metal/conjugated polymer interfaces. The work is partially motivated by recent experiments in which injection of spin polarized electrons from ferromagnetic contacts into thin films of conjugated polymers was reported. We use a one-dimensional nondegenerate Su-Schrieffer-Heeger (SSH) Hamiltonian to describe the conjugated polymer and one-dimensional tight-binding models to describe the ferromagnetic metal. We consider both a model for a conventional ferromagnetic metal, in which there are no explicit structural degrees of freedom, and a model for a half-metallic ferromagnetic colossal magnetoresistance (CMR) oxide which has explicit structural degrees of freedom. The Fermi energy of the magnetic metallic contact is adjusted to control the degree of electron transfer into the polymer. We investigate electron charge and spin transfer from the ferromagnetic metal to the organic polymer, and structural relaxation near the interface. Bipolarons are the lowest energy charge state in the bulk polymer for the nondegenerate SSH model Hamiltonian. As a result electrons (or holes) transferred into the bulk of the polymer form spinless bipolarons. However, there can be spin density in the polymer localized near the interface.

description: We first exhibit two compatible Poisson structures on the cotangent bundle of the unitary group $\mathrm{U}(n)$ in such a way that the invariant functions of the $\mathfrak{u}(n)^*$-valued momenta generate a bi-Hamiltonian hierarchy. One of the Poisson structures is the canonical one and the other one arises from embedding the Heisenberg double of the Poisson-Lie group $\mathrm{U}(n)$ into $T^*\mathrm{U}(n)$, and subsequently extending the embedded Poisson structure to the full cotangent bundle. We then apply Poisson reduction to the bi-Hamiltonian hierarchy on $T^*\mathrm{U}(n)$ using the conjugation action of $\mathrm{U}(n)$, for which the ring of invariant functions is closed under both Poisson brackets. We demonstrate that the reduced hierarchy belongs to the overlap of well-known trigonometric spin Sutherland and spin Ruijsenaars--Schneider type integrable many-body models, which receive a bi-Hamiltonian interpretation via our treatment.

description: Vorurteile prägen unseren Alltag wie kaum etwas anderes. Durch Kategorisierungen werden fortlaufend Entscheide getroffen und Personen werden bevorzugt oder benachteiligt. Die dadurch entstehende Konstruktion einer Eigen- und Fremdgruppe fördert rassistische Denkweisen, die in alltäglichen Situationen durch diskriminierendes Verhalten deutlich werden. Auch bei Jugendlichen sind solche Ansichten präsent. Da sich Jugendliche in einer Phase der Identitätsentwicklung befinden und ihre Werte für sich definieren, lässt sich vermuten, dass im Jugendalter Themen wie Alltagsrassismus gewinnbringend angegangen und reflektiert werden können. Unter einem sozialräumlichen Blickwinkel wurden Handlungsoptionen erarbeitet, die in ländlicher Jugendarbeit genutzt werden können. Mit dem Fokus auf den Sozialraum sind verschiedene Spezifikas von ländlichen Räumen in der Schweiz dargestellt, die von der Jugendarbeit berücksichtigt werden müssen. Die Kernfrage dieser Arbeit lautet deshalb: Wie kann sozialräumliche Jugendarbeit auf dem Land auf Alltagsrassismus und Diskriminierung reagieren? Soziokulturelle Arbeitsprinzipien bilden dabei die Ausgangslage, welche von Sozialpädagogischen Betrachtungen und Ansätzen ergänzt werden. Ziel dieser Arbeit ist es somit, Methoden aufzuzeigen, die einen interdisziplinären Umgang mit Alltagsrassismus in einer sozialräumlichen Jugendarbeit ermöglichen und von Jugendarbeitenden direkt angewandt werden können.

description: Additional file 2: Figure S2. Crossing scheme for creating isogenic BL2 reporter lines. The BL2 reporter on the Y chromosome was first crossed into a balancer stock to recoverÂ the second and third chromosome dominant markers. The F1 male progeny with second and third chromosomes dominantly marked were selected to cross with female virgins of the A1 inbred line. A single F2 male progeny (blue rectangle) was selected to back cross to 3~5 A1 inbred line female virgins. The F3 progeny that have no balancer chromosomes will have the BL2 reporter in the A1 background with a non-A1 4th chromosome floating in the population. Note that the non-A1 4th chromosome was introduced from a single F2 male, which means that in the F3 population there are only two genotypes of the 4th chromosome (denoted 39C-12 and +iso respectively). The F3 virgin flies that have no balancer chromosomes were selected to create a floating stock. In order to separate the 39C-12 chromosome from +iso chromosome, single sibling pairs from the F3 floating stock were isolated to create multiple stocks; the 39C-12 reporter expression in all female fly eyes was followed by visual inspection for several generations in order to identify a homozygous 39C-12 stock (i.e. the exact A1 background with the Y chromosome containing the BL2 reporter). The same approach was used to transfer the BL2 reporter to the D1 genetic background.

description: Presented are two kinds of integral solutions to the quantum Knizhnik-Zamolodchikov equations for the 2n-point correlation functions of the Heisenberg XYZ antiferromagnet. Our first integral solution can be obtained from those for the cyclic SOS model by using the vertex-face correspondence. By the construction, the sum with respect to the local height variables k_0, k_1, >..., k_{2n} of the cyclic SOS model remains other than n-fold integral in the first solution. In order to perform those summations, we improve that to find the second integral solution of (r+1)n-fold integral for r in Z_{>1}, where r is a parameter of the XYZ model. Furthermore, we discuss the relations among our formula, Lashkevich-Pugai's formula and Shiraishi's one.

Der Auftrag der Sozialpädagogik bei erwachsenen Menschen mit einer kognitiven Beeinträchtigung im stationären Wohnbereich des Kantons Luzern: Wie haben sich der Auftrag und die Rahmenbedingungen in den letzten 10 Jahren verändert? Eine qualitative Forschungsarbeit
Creators: name: Canova, Numa

description: In der sehr schnelllebigen und änderungsreichen Zeit, in der wir heute leben, verändern sich Dinge in kurzer Zeit und müssen sich laufend den aktuellen Gegebenheiten anpassen. So auch die Sozialpädagogik. Durch Veränderungen wie der Verknappung der zur Verfügung stehenden Mittel und der Zeit, aber auch durch neue Leitprinzipien, Konzepte, und Ideen verändert sich einerseits der Auftrag, den professionelle Sozialpädagog_innen zu erfüllen haben, andererseits ändern sich auch die Rahmenbedingungen um diesen Auftrag zu erfüllen. Wie sich der Auftrag und die Rahmenbedingungen, die ihn beeinflussen, verändert haben wird mit den Erkenntnissen aus Fachdiskurs, Medien und der Lage des Kantons Luzern herausgearbeitet und durch die Befragungen an Professionelle der Sozialpädagogik verknüpft. So wird versucht, das Verhältnis zwischen den sich scheinbar entgegenlaufenden Entwicklungen, immer höherer Forderungen und den immer knapperen Ressourcen, zu beleuchten. Der Sicht der Professionellen im Kanton Luzern wird dabei besonders Rechnung getragen. Es hat sich gezeigt, dass neue Entwicklungen wie die Ökonomisierung nicht nur negative Effekte haben und die Erfüllung des sozialpädagogischen Auftrags im Kanton Luzern trotz widriger Rahmenbedingungen, aus Sicht der professionellen noch immer möglich ist. Folgen der Sparmassnahmen in der Praxis sind nicht überall ganz so dramatisch wie sie von den Medien dargestellt werden, aber trotzdem an einem Punkt ist, an dem weiterer Lesitungsabbau zu geringerer Qualität führen würde. Es braucht gut ausgebildetes und innovatives Personal in den Institutionen damit die Herausforderungen von heute gemeistert werden können.

description: In this paper, we explore the possibility that a light dilaton can be the first sign of new physics at the LHC. The dilaton could emerge in approximate scale invariant UV completions of the SM as the Goldstone boson associated with the spontaneous breaking of the scale invariance. We study in detail the phenomenology of the dilaton at the LHC in the mass range of [$10-300$] GeV including the case where the dilaton can mix with the SM Higgs boson, leading to an interesting interplay between direct and indirect constraints. A possibility that the dilaton acts as a portal to a dark sector is also considered. As a minimal realization, the dark sector includes a dark photon lighter than the dilaton implying sizeable missing energy signatures. Several simplified benchmark models that can encode different UV completions are discussed, for which we scrutinize the current and future LHC reach.

description: Magnetic skyrmion, topologically non-trivial spin texture, has been considered as promising information carrier in future electronic devices because of its nanoscale size, low depinning current density and high motion velocity. Despite the broad interests in skyrmion racetrack memory, researchers have been recently exploiting logic functions enabled by using the particle-like behaviors of skyrmions. These functions can be applied to unconventional computing, such as stochastic computing (SC), which treats data as probabilities and is superior to binary computing due to its simplicity of logic operation. In this work, we demonstrate SC implemented by skyrmionic logic devices. We propose a skyrmionic AND-OR logic device as a multiplier in the stochastic domain and two skyrmionic multiplexer (MUX) logic devices as stochastic adders. With the assist of voltage controlled magnetic anisotropy (VCMA), the precise control of skyrmions collision is not required in the skyrmionic AND-OR logic device, thus improving the operation robustness. In the two MUX logic devices, skyrmions can be driven by Zhang-Li torque or spin orbit torque (SOT). Particularly, we can flexibly regulate the skyrmion motion by VCMA or voltage controlled Dzyaloshinskii-Moriya Interaction (VCDMI) in the SOT case. Furthermore, 3-bit stochastic multiplier and adder are demonstrated by micromagnetic simulations. In addition, simulations in synthetic antiferromagnets (SAF) show that the performance of our skyrmionic logic gates can be optimized through advanced materials. Our work opens up perspective to implement SC using skyrmionic logic devices.

description: We present a numerical study of Riemann's formula for the oscillating part of the density of the primes and their powers. The formula is comprised of an infinite series of oscillatory terms, one for each zero of the zeta function on the critical line and was derived by Riemann in his paper on primes assuming the Riemann hypothesis. We show that high resolution spectral lines can be generated by the truncated series at all powers of primes and demonstrate explicitly that the relative line intensities are correct. We then derive a Gaussian sum rule for Riemann's formula. This is used to analyze the numerical convergence of the truncated series. The connections to quantum chaos and semiclassical physics are discussed.

description: Integration ist gemäss der Integrationsstrategie des Bundes eine gesamtgesellschaftliche Aufgabe. Am wirkungsvollsten geschieht sie, wo Menschen zusammenleben, in Kantonen und Gemeinden. In Steffisburg, einer grossen Agglomerationsgemeinde im Berner Oberland bestehen zwar verschiedene Integrationsangebote jedoch nahm die Zahl der Teilnehmenden im vergangenen Jahr laut der Fachkommission für Integration und Familie ab. Kerstin de Bruin, Anna Mac Donald und Vinzenz Niklaus zeigen in der vorliegenden Bachelorarbeit auf, welche Faktoren aus Sicht von Betroffenen für die Teilnahme an Integrationsangeboten wichtig sind, was sich förderlich auf ihren Integrationsprozess in die Regelstruktur auswirkt und inwiefern die Soziale Arbeit in diesem Prozess unterstützend wirken kann. Problemzentrierte Leitfadeninterviews mit Zugewanderten, welche unterschiedlich lange in der Schweiz leben und aus verschiedenen Herkunftsländern stammen dienen als Datenbasis. Anhand eines thematischen Vergleichs wurden wiederkehrende Themen in den Interviews identifiziert und in einem Reduktionsprozess relevante Faktoren für die Erreichbarkeit und Nutzung von Integrationsangeboten herausgearbeitet. Sprache, Arbeit und insbesondere soziale Beziehungen sind gemäss Forschungsergebnissen die Faktoren, welche die Erreichbarkeit von Integrationsangeboten begünstigen, während das Engagement von Freiwilligen und weitere lebensweltorientierte Angebote die Nutzung fördern. Für die Soziale Arbeit ergibt sich im Bereich der Gemeinwesenarbeit ein wichtiges Handlungsfeld.

Partizipation von Kindern und Jugendlichen in der Heimerziehung: Zum Umgang mit Herausforderungen und Spannungsfeldern

description: In der vorliegenden Bachelorarbeit setzt sich Simone Dietsche mit den Herausforderungen und Spannungsfeldern, welche die Kinder- und Jugendpartizipation im Heimkontext mit sich bringt, auseinander. Anhand von Forschungsergebnissen aus dem deutschsprachigen Raum, sammelt, kategorisiert und ergründet sie aktuelle Hindernisse, mit welchen sich die sozialpädagogischen Fachpersonen konfrontiert sehen. Anschliessend unternimmt sie den Versuch (Handlungs-)Schlüsse für eine Professionalisierung der derzeitigen Partizipationspraxis in der Heimerziehung aufzuzeigen. Im Verlauf der Arbeit wurde ersichtlich, dass viele der Herausforderungen mit einer fehlenden «Partizipationskultur» in den Einrichtungen zusammenhängen. Unter einer Partizipationskultur wird verstanden, dass partizipative Verfahren in den Strukturen und Abläufen der Einrichtungen eingebettet sind und ein sogenanntes «Klima der Beteiligung» besteht. Der Aufbau von partizipationsfreundlichen Strukturen und einem partizipationsfreundlichen Klima bedingt entsprechende Fach- und Methodenkompetenzen der Einrichtungsleitung und Fachpersonen. Gleichzeitig erschweren Ansprüche wie Kontrolle und Wirtschaftlichkeit, welche die sozialpädagogische Umwelt an die Heimerziehung stellt, den Aufbau einer Partizipationskultur. Simone Dietsche kommt in ihrer Arbeit zum Schluss, dass für eine Professionalisierung der Partizipationspraxis Handlungspotenzial auf Ebene der Ausbildung der angehenden Fachpersonen, auf Ebene der Einrichtung und auf Ebene der sozialpädagogischen Umwelt besteht.

The Progenitors of Calcium-Strong Transients

description: A new class of faint, spectroscopically peculiar transients has emerged in the last decade. We term these events "calcium-strong transients" (CaSTs) because of their atypically high calcium-to-oxygen nebular line ratios. Previous studies have struggled to deduce the identity of their progenitors due to a combination of their extremely extended radial distributions with respect to their host galaxies and their relatively high rate of occurrence. In this work, we find that the CaST radial distribution is consistent with the radial distribution of two populations of stars: old (ages > 5 Gyr), low-metallicity (Z/Zsol < 0.3) stars and globular clusters. While no obvious progenitor scenario arises from considering old, metal-poor stars, the alternative production site of globular clusters leads us to narrow down the list of possible candidates to three binary scenarios: mergers of helium and oxygen/neon white dwarfs; tidal disruptions of helium white dwarfs by neutron stars; and stable accretion from low-mass helium-burning stars onto white dwarfs. While rare in the field, these binary systems can be formed dynamically at much higher rates in globular clusters. Subsequent binary hardening both increases their interaction rate and ejects them from their parent globular clusters prior to mass transfer contact. Their production in, and ejection from, globular clusters may explain their radial distribution and the absence of globular clusters at their explosion site. This model predicts a currently undiscovered high rate of CaSTs in nuclear star clusters. Alternatively, an undetermined progenitor scenario involving old, low-metallicity stars may instead hold the key to understanding CaSTs.

description: Modern-days CMOS-based computation technology is reaching its fundamental limitations. The emerging field of magnonics, which utilizes spin waves for data transport and processing, proposes a promising path to overcome these limitations. Different devices have been demonstrated recently on the macro- and microscale, but the feasibility of the magnonics approach essentially relies on the scalability of the structure feature size down to an extent of a few 10 nm, which are typical sizes for the established CMOS technology. Here, we present a study of propagating spin-wave packets in individual yttrium iron garnet (YIG) conduits with lateral dimensions down to 50 nm. Space and time resolved micro-focused Brillouin-Light-Scattering (BLS) spectroscopy is used to characterize the YIG nanostructures and measure the spin-wave decay length and group velocity directly. The revealed magnon transport at the scale comparable to the scale of CMOS proves the general feasibility of a magnon-based data processing.

description: We calculate the leading and next-to-leading logarithmic resummed distribution for the jet broadening in deep inelastic scattering, as well as the power correction for both the distribution and mean value. A truncation of the answer at NLL accuracy, as is standard, leads to unphysical divergences. We discuss their origin and show how the problem can be resolved. We then examine DIS-specific procedures for matching to fixed-order calculations and compare our results to data. One of the tools developed for the comparison is an NLO parton distribution evolution code. When compared to PDF sets from MRST and CTEQ it reveals limited discrepancies in both.

description: The TOV equation appears as the relativistic counterpart of the classical condition for hydrostatic equilibrium. In the present work we aim at showing that a generalised TOV equation also characterises the equilibrium of models endowed with other symmetries besides spherical. We apply the dual null formalism to spacetimes with two dimensional spherical, planar and hyperbolic symmetries with a perfect fluid as the source. We also assume a Killing vector field orthogonal to the surfaces of symmetry, which gives us static solutions, in the timelike Killing field case, and homogeneous dynamical solutions in the case the Killing field is spacelike. In order to treat equally all the aforementioned cases, we discuss the definition of a quasi-local energy for the spacetimes with planar and hyperbolic foliations, since the Hawking-Hayward definition only applies to compact foliations. After this procedure, we are able to translate our geometrical formalism to the fluid dynamics language in a unified way, to find the generalized TOV equation, for the three cases when the solution is static, and to obtain the evolution equation, for the homogeneous spacetime cases. Remarkably, we show that the static solutions which are not spherically symmetric violate the weak energy condition (WEC). We have also shown that the counterpart of the TOV equation for the spatially homogeneous models is just the familiar equation \r{ho} + P = 0, defining a cosmological constant-type behaviour, both in the hyperbolic and spherical cases. This implies a violation of the strong energy condition in both cases, added to the above mentioned violation of the weak energy condition in the hyperbolic case. We illustrate our unified treatment obtaining analogs of Schwarzschild interior solution, for an incompressible fluid $ρ= ρ_0$ constant.

Wer macht denn sowas?! Sexualbegleiterinnen und Sexualbegleiter in der Schweiz und ihre Unterstützung durch die Soziale Arbeit

description: Sexualität von Menschen mit Beeinträchtigung ist ein Thema, dass auch heute noch von vielen Tabus geprägt ist. Die vorliegende Bachelorarbeit von Julia Gabriel befasst sich mit der Sexualität von Menschen mit Beeinträchtigung, insbesondere aber mit dem Thema Sexualbegleitung. Sexualbegleiterinnen und Sexualbegleiter werden zu ihren Erfahrungen und Wünschen befragt. Ziel dieser Arbeit ist es, eine Handlungsempfehlung für die Soziale Arbeit zu formulieren, wie Sexualbegleiterinnen und Sexualbegleiter besser unterstützt werden können. Noch vor 50 Jahren wurde Sexualität von Menschen mit Beeinträchtigung mit verschiedenen Bemühungen zu verhindern versucht. Erst durch Bekanntmachung des Normalisierungsprinzips in den 90er Jahren fand ein Umdenken statt. In Deutschland gab es schon 1995 erste Vorläufer der Sexualbegleitung, in der Schweiz startete 2003 ein erster Versuch durch die Pro Infirmis, dieser scheiterte aber. Heute gibt es mehrere verschiedene Organisationen und auch Einzelpersonen die Ausbildungen zur Sexualbegleitung anbieten. Momentan empfinden Sexualbegleiterinnen und Sexualbegleiter besonders die Zusammenarbeit mit Institutionen als Unterstützung durch die Soziale Arbeit. Gemäss Interviews müsste das Betreuungspersonal aber besser geschult werden, um das Bewusstsein von Sexualbegleitung zu erhöhen. Auch auf politischer Ebene muss sich die Soziale Arbeit vermehrt einsetzten.

Search for supersymmetry using Higgs boson to diphoton decays at $\sqrt{s} =$ 13 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2019
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for supersymmetry (SUSY) is presented where at least one Higgs boson is produced and decays to two photons in the decay chains of pair-produced SUSY particles. Two analysis strategies are pursued: one focused on strong SUSY production and the other focused on electroweak SUSY production. The presence of charged leptons, additional Higgs boson candidates, and various kinematic variables are used to categorize events into search regions that are sensitive to different SUSY scenarios. The results are based on data from proton-proton collisions at the Large Hadron Collider at a center-of-mass energy of 13 TeV collected by the CMS experiment, corresponding to an integrated luminosity of 77.5 fb$^{-1}$. No statistically significant excess of events is observed relative to the standard model expectations. We exclude bottom squark pair production for bottom squark masses below 530 GeV and a lightest SUSY particle mass of 1 GeV; wino-like chargino-neutralino production in gauge-mediated SUSY breaking (GMSB) for chargino and neutralino masses below 235 GeV with a gravitino mass of 1 GeV; and higgsino-like chargino-neutralino production in GMSB, where the neutralino decays exclusively to a Higgs boson and a gravitino for neutralino masses below 290 GeV.

description: The discrete self-trapping equation (DST) represents an useful model for several properties of one-dimensional nonlinear molecular crystals. The modulational instability of DST equation is discussed from a statistical point of view, considering the oscillator amplitude as a random variable. A kinetic equation for the two-point correlation function is written down, and its linear stability is studied. Both a Gaussian and a Lorentzian form for the initial unperturbed wave spectrum are discussed. Comparison with the continuum limit (NLS equation) is done.

description: The determination of node centrality is a fundamental topic in social network studies. As an addition to established metrics, which identify central nodes based on their brokerage power, the number and weight of their connections, and the ability to quickly reach all other nodes, we introduce five new measures of Distinctiveness Centrality. These new metrics attribute a higher score to nodes keeping a connection with the network periphery. They penalize links to highly-connected nodes and serve the identification of social actors with more distinctive network ties. We discuss some possible applications and properties of these newly introduced metrics, such as their upper and lower bounds. Distinctiveness centrality provides a viewpoint of centrality alternative to that of established metrics.
Cohesion induced deepening transition of avalanches
Creators: name: Chen, Chun-Chung
Publisher: name: arXiv
Year: 2002
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: A directed avalanche model with a control parameter is introduced to describe the transition between cohesive and noncohesive granular material. The underlying dynamics of the process can be mapped to interface growth model. In that representation, a continuous phase transition separates the rough phase and the flat phase. In the avalanche formulation, this corresponds to a transition from deep to shallow avalanches. The scaling exponents of the avalanches indeed follow those of the underlying interface growth in both phases and at the transition point. However, the mass hyperscaling relation is broken at the transition point due to the fractal nature of the avalanche and a hierarchy of critical directed percolation processes.

description: In adaptive optics, to compensate for the distortion effects introduced along the propagation path between a light source and a receiver (telescope lens), it is important to estimate certain optical parameters of the turbulence, such as the outer scale L_0 and Fried\'s parameter r_0. The outer scale is however a model-dependent variable.

In this work, a theoretical analysis of the mathematical derivation and a comparison of the puntual covariances and the covariances of the arrival angles averaged over square apertures of finite size (called general) for each of the spectral models considered: Von KarmAn, Greenwood, Exponential and the classical Kolmogorov model. An important difference between these covariances is that the general covariance has an associated validity limit depending on the external scale and the diameter of the apertures.

On the other hand, an empirical analysis has been carried out by fitting the theoretical models to data obtained from the telemetry of the Paranal AOF system. Empirical cross-sectional and longitudinal covariances are obtained from the AOF telemetry slope measurements. By fitting this set of empirical covariances we seek to estimate the turbulence parameters (r_0, L_0), the measurement error, \\sigma_e, and the TT contribution of the laser guide star jitter, \\sigma_{s_\\phi}. The aim is therefore to determine which model provides the best fits under certain criteria of algorithm optimality, compilation times, among others.

Discovery of A Mg II Changing-look AGN and its Implications for a Unification Sequence of Changing-look AGNs

description: Changing-Look (CL) is a rare phenomenon of Active Galactic Nuclei (AGNs) that exhibit emerging or disappearing broad lines accompanied by continuum variations on astrophysically short timescales ($\lesssim$ 1 yr to a few decades). While previous studies have found Balmer-line (broad H$α$ and/or H$β$) CL AGNs, the broad Mg II line is persistent even in dim states. No unambiguous Mg II CL AGN has been reported to date. We perform a systematic search of Mg II CL AGNs using multi-epoch spectra of a special population of Mg II-emitters (characterized by strong broad Mg II emission with little evidence for AGN from other normal indicators such as broad H$α$ and H$β$ or blue power-law continua) from the Fourteenth Data Release of the Sloan Digital Sky Survey. We present the discovery of the first unambiguous case of an Mg II CL AGN, SDSS J152533.60+292012.1 (at redshift $z$ = 0.449), which is turning off within rest-frame 286 days. The dramatic diminishing of Mg II equivalent width (from 110 $\pm$ 26 Angstrom to being consistent with zero), together with little optical continuum variation ($ΔV_{\rm max-min}$ $=$ 0.17 $\pm$ 0.05 mag) coevally over $\sim$ 10 years, rules out dust extinction or a tidal disruption event. Combined with previously known H$β$ CL AGNs, we construct a sequence that represents different temporal stages of CL AGNs. This CL sequence is best explained by the photoionization model of Guo et al. (2019). In addition, we present two candidate turn-on Mg II CL AGNs and a sample of 361 Mg II-emitters for future Mg II CL AGN searches.

description: this paper examines the effects of import quotas and foreign exports subsidies on the size of rents from U.S. cheese imports and their division among importers and exporters. Consumers pay a hefty portion of the wholesale price in rents and tariffs; EC's subsidization of cheese exports to the United States has served primarily to maintain rents.

Phases of bosonic strings and two dimensional gauge theories

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We suggest that the extrinsic curvature and torsion of a bosonic string can be employed as variables in a two dimensional Landau-Ginzburg gauge field theory. Their interpretation in terms of the abelian Higgs multiplet leads to two different phases. In the phase with unbroken gauge symmetry the ground state describes open strings while in the phase with broken gauge symmetry the ground state involves closed strings. When we allow for an additional abelian gauge structure along the string, we arrive at an interpretation in terms of the two dimensional SU(2) Yang-Mills theory.

Cloud fragmentation cascades and feedback: on reconciling an unfettered inertial range with a low star formation rate

description: Molecular cloud complexes exhibit both (i) an unfettered Larson-type spectrum over much of their dynamic range, whilst (ii) still producing a much lower star-formation rate than were this cascade to remain unfettered all the way down to star-forming scales. Here we explain the compatibility of these attributes with minimalist considerations of a mass-conserving fragmentation cascade, combined with estimates of stellar feedback. Of importance is that the amount of feedback needed to abate fragmentation and truncate the complex decreases with decreasing scale. The scale at which the feedback momentum matches the free-fall momentum marks a transition scale below most of the cascade is truncated and the molecular cloud complex dissipated. For a $10^6M_\odot$ GMC complex starting with radius of $\sim 50$pc, the combined feedback from young stellar objects, supernovae, radiation, and stellar winds for a GMC cloud complex can truncate the cascade within an outer free-fall time but only after the cascade reaches parsec scales.
