description: Esta investigación hace foco en tres aspectos determinantes para entender cómo se da el proceso de representación social de la violencia en la subregión de los Montes de María, en un periodo determinado de los noticieros de Telecaribe. Si bien todos representamos al darle significado a algo o alguien, la representación ejercida por un grupo, en este caso, noticieros de televisión que señalan cubrir e informar a todo el Caribe colombiano, cobra particular interés. Las fuentes de información, la cobertura geográfica que dan a determinadas noticias, y cómo entienden y traducen hechos de violencia que padecen las comunidades para luego reflejarlas en pantalla, hace parte de una función social y un ejercicio de poder que legitima y alimenta el ciclo de las representaciones sociales. Para concluir que los noticieros de Telecaribe invisibilizaron hechos representativos de la subregión de los Montes de María al no informarlos con el mismo despliegue de medios nacionales, se recurrió a la selección de una muestra de emisiones de dichos noticieros (25 emisiones) en un periodo en el que se registraron hechos de interés para la subregión.

description: The main objective of this work is to improve the energy-efficiency (EE) of a multiple access channel (MAC) system, through power control, in a distributed manner. In contrast with many existing works on energy-efficient power control, which ignore the possible presence of a queue at the transmitter, we consider a new generalized cross-layer EE metric. This approach is relevant when the transmitters have a non-zero energy cost even when the radiated power is zero and takes into account the presence of a finite packet buffer and packet arrival at the transmitter. As the Nash equilibrium (NE) is an energy-inefficient solution, the present work aims at overcoming this deficit by improving the global energy-efficiency. Indeed, as the considered system has multiple agencies each with their own interest, the performance metric reflecting the individual interest of each decision maker is the global energy-efficiency defined then as the sum over individual energy-efficiencies. Repeated games (RG) are investigated through the study of two dynamic games (finite RG and discounted RG), whose equilibrium is defined when introducing a new operating point (OP), Pareto-dominating the NE and relying only on individual channel state information (CSI). Accordingly, closed-form expressions of the minimum number of stages of the game for finite RG (FRG) and the maximum discount factor of the discounted RG (DRG) were established. The cross-layer model in the RG formulation leads to achieving a shorter minimum number of stages in the FRG even for higher number of users. In addition, the social welfare (sum of utilities) in the DRG decreases slightly with the cross-layer model when the number of users increases while it is reduced considerably with the Goodman model. Finally, we show that in real systems with random packet arrivals, the cross-layer power control algorithm outperforms the Goodman algorithm.

description: Near-infrared (2.5-5.0$\,μ$m) low-resolution ($λ/Δλ{\sim}100$) spectra of 72 Galactic planetary nebulae (PNe) were obtained with the Infrared Camera (IRC) in the post-helium phase. The IRC, equipped with a $1'{\times}1'$ window for spectroscopy of a point source, was capable of obtaining near-infrared spectra in a slit-less mode without any flux loss due to a slit. The spectra show emission features including hydrogen recombination lines and the 3.3-3.5$\,μ$m hydrocarbon features. The intensity and equivalent width of the emission features were measured by spectral fitting. We made a catalog providing unique information on the investigation of the near-infrared emission of PNe. In this paper, details of the observations and characteristics of the catalog are described.

description: Esta investigación se enfoca en los trabajos artesanales y en los estudio de los imaginarios culturales y dinámicas de campo que se desarrollan en la población artesana de San Jacinto, Bolívar. Un estudio de campo de enfoque sociocultural, que se compone de experiencias vividas de un colectivo de voces artesanas que luchan por mantener y evolucionar en sus tradiciones, ya que estas labores fueron de cierta forma una superación de la guerra, una ilusión en medio de un panorama desalentador que les permitía a sus pobladores alzar el vuelo y emprender nuevos proyectos que favorecieran tanto a sus habitantes cómo a la población en general. Es una investigación de tipo descriptiva donde se estudian y describen las influencias de los capitales culturales, el concepto de cultura, las diferentes dinámicas de campo suministradas por el sociólogo Pierre Bourdieu, la construcción de los imaginarios desde diversos puntos de vistas y como estos han influido en el desarrollo de la comunidad artesana; haciendo además mención sobre algunos códigos lingüísticos utilizados por esta comunidad de hablantes.

description: Las figuras literarias se han empleado para embellecer las obras de innumerables autores a lo largo de la historia. Este trabajo presenta un análisis de Símil y la alegoría en las canciones vallenatas que tuvieron éxitos en la Costa Caribe colombiana durante el periodo de 1970 al 1990, que como figuras literarias ayudaron a preservar en la música los valores, costumbres y tradiciones de la sociedad de la época. Estas canciones, además de ser textos poéticos, se pueden considerar discursos que generaron sentido de pertenencia construidos desde la interacción de los sujetos y su entorno. El estudio de los elementos culturales desde la literatura construyen a enriquecer el saber natural y distinguir la dinámica del lenguaje como un proceso vivo e inseparable como un proceso de la misma sociedad.

Er zeigt an drei beispielhaft ausgewählten Erzählungen (einer Fabel, einem historischen Exempel, einem Gleichnis), über welche Möglichkeiten die Kurzerzählungen verfügen, um die Relation zwischen Erzählung (narratio) und Epimythion (moralisatio) je neu zu entwerfen. Von jeder der drei Kurzerzählungen werden verschiedene Fassungen vorgestellt, die je kontextabhängig unterschiedliche narrative und argumentative Techniken nutzen, um aus einer Erzählung verschiedene Schlüsse zu ziehen und damit ihr rhetorisches Potential voll auszuschöpfen.

description: In the course of the MUCHFUSS project we have recently discovered four radial velocity (RV) variable, hot (Teff $\approx$ 80,000 - 110,000 K) post-asymptotic giant branch (AGB) stars. Among them, we found the first known RV variable O(He) star, the only second known RV variable PG 1159 close binary candidate, as well as the first two naked (i.e., without planetary nebula (PN)) H-rich post-AGB stars of spectral type O(H) that show significant RV variations. We present a non-LTE spectral analysis of these stars along with one further O(H)-type star whose RV variations were found to be not significant. We also report the discovery of an far-infrared excess in the case of the PG 1159 star. None of the stars in our sample displays nebular emission lines, which can be explained well in terms of a very late thermal pulse evolution in the case of the PG 1159 star. The "missing" PNe around the O(H)-type stars seem strange, since we find that several central stars of PNe have much longer post-AGB times. Besides the non-ejection of a PN, the occurrence of a late thermal pulse, or the re-accretion of the PN in the previous post-AGB evolution offer possible explanations for those stars not harbouring a PN (anymore). In case of the O(He) star J0757 we speculate that it might have been previously part of a compact He transferring binary system. In this scenario, the mass transfer must have stopped after a certain time, leaving behind a low mass close companion that could be responsible for the extreme RV shift of 107.0 $\pm$ 22.0 km/s measured within only 31 min.

Bei näherer Betrachtung zeigt sich aber, dass Paulis Schwänke hochkomplexe Gebilde sind, die gerade durch Sinnirritationen eine differenzierte Interpretationsweise anregen. Ihre moralische Ebene wird dadurch vielschichtig und bedient unterschiedliche Abstraktionsniveaus innerhalb eines Schwanks. Der Beitrag zeigt diese Vielschichtigkeit am Beispiel der Darstellung von Spiel als Sünde.

description: We apply a combination of a Genetic Algorithms (GA) and Support Vector Machines (SVM) machine learning algorithm to solve two important problems faced by the astronomical community: star/galaxy separation, and photometric redshift estimation of galaxies in survey catalogs. We use the GA to select the relevant features in the first step, followed by optimization of SVM parameters in the second step to obtain an optimal set of parameters to classify or regress, in process of which we avoid over-fitting. We apply our method to star/galaxy separation in Pan-STARRS1 data. We show that our method correctly classifies 98% of objects down to i_P1= 24.5, with a completeness (or true positive rate) of 99% for galaxies, and 88% for stars. By combining colors with morphology, our star/classification method yields better results than the new SExtractor classifier spread_model in particular at the faint end (i_P1>22). We also use our method to derive photometric redshifts for galaxies in the COSMOS bright multi-wavelength dataset down to an error in (1+z) of sigma=0.013, which compares well with estimates from SED fitting on the same data (sigma=0.007) while making a significantly smaller number of assumptions.

description: Decades ago two classes of gamma-ray bursts were identified and delineated as having durations shorter and longer than about 2 s. Subsequently indications also supported the existence of a third class. Using maximum likelihood estimation we analyze the duration distribution of 888 Swift BAT bursts observed before October 2015. Fitting three log-normal functions to the duration distribution of the bursts provides a better fit than two log-normal distributions, with 99.9999% significance. Similarly to earlier results, we found that a fourth component is not needed. The relative frequencies of the distribution of the groups are 8% for short, 35% for intermediate and 57% for long bursts which correspond to our previous results. We analyse the redshift distribution for the 269 GRBs of the 888 GRBs with known redshift. We find no evidence for the previously suggested difference between the long and intermediate GRBs' redshift distribution. The observed redshift distribution of the 20 short GRBs differs with high significance from the distributions of the other groups.

description: Innerhalb einer tugendethischen Moraldidaxe geht es nicht darum, feststehende Normen zu vermitteln, sondern den Belehrten in die Lage zu versetzen, situativ richtig zu reagieren. Ziel ist es, ihn zur Erkenntnis anzuregen: zur Selbsterkenntnis, zur Erkenntnis des Guten und zur Gotteserkenntnis. Exempel leisten innerhalb der vormodernen Ethik einen wichtigen Beitrag zu diesem Erkenntnisgewinn. Sie sind in vielen Fällen keineswegs simple und einschichtig konzipierte Erzählungen, die einen bloßen Sachverhalt illustrieren, auch wenn die moralisatio dies bisweilen nahelegen mag. Am Beispiel der ‚Geschichte zweier Kaufleute‘ aus dem Schachzabelbuch Heinrichs von Beringen wird gezeigt, wie die exempla in einer durch die hermeneutische Praxis des mehrfachen Schriftsinns geschulten polysemen Lektürehaltung neben der illustratio der Verinnerlichung des Gelehrten (imaginatio) dienen und den erkennenden Blick auf Gott eröffnen können (ostentio).

description: Im ‚Feigen Ehemann‘ wird die narratio durch das Epimythion unterlaufen. Entgegen der Darstellung auf der discours-Ebene stimmt die Erzählerstimme hier der Marginalisierung der Vergewaltigung als schädlein zu. In den ‚Drei Mönchen von Kolmar‘ wird dem Epimythion zufolge nur der vierte Mönch zu Unrecht ermordet, während der Mord an den drei Mönchen aus der axiologischen Diskussion herausgehalten wird. Wenn sich Epimythien zumindest axiologisch ambivalent zur evaluativen Struktur der narratio verhalten, werden gegen zuvor etablierte axiologische Konzepte nun Äußerungen einer hierarchisch privilegierten Instanz in Widerspruch gebracht – ein perfides Erzählen, das ein didaktisch-exemplarisches Deuten limitiert.

description: Given a sequence of asymptotically flat 3-manifolds of nonnegative scalar curvature with outermost minimal boundary, converging in the pointed $C^0$ Cheeger--Gromov sense to an asymptotically flat limit space, we show that the total mass of the limit is bounded above by the liminf of the total masses of the sequence. In other words, total mass is lower semicontinuous under such convergence. In order to prove this, we use Huisken's isoperimetric mass concept, together with a modified weak mean curvature flow argument. We include a brief discussion of Huisken's work before explaining our extension of that work. The results are all specific to three dimensions.

description: We propose an extension of the standard model of quarks and leptons to include gauge $B-L$ symmetry with an exotic array of neutral fermion singlets for anomaly cancellation. With the addition of suitable scalars also transforming under $U(1)_{B-L}$, this becomes a model of radiative seesaw neutrino mass with possible multipartite dark matter. If leptoquark fermions are added, necessarily also transforming under $B-L$, the diphoton excess at 750 GeV, recently observed at the Large Hadron Collider, may also be explained.

description: Supernovae (SNe) embedded in dense circumstellar material (CSM) may show prominent emission lines in their early-time spectra ($\leq 10$ days after the explosion), owing to recombination of the CSM ionized by the shock-breakout flash. From such spectra ("flash spectroscopy"), we can measure various physical properties of the CSM, as well as the mass-loss rate of the progenitor during the year prior to its explosion. Searching through the Palomar Transient Factory (PTF and iPTF) SN spectroscopy databases from 2009 through 2014, we found 12 Type II SNe showing flash-ionized (FI) signatures in their first spectra. All are younger than 10 days. These events constitute 14\% of all 84 SNe in our sample having a spectrum within 10 days from explosion, and 18\% of SNe~II observed at ages $<5$ days, thereby setting lower limits on the fraction of FI events. We classified as "blue/featureless" (BF) those events having a first spectrum which is similar to that of a black body, without any emission or absorption signatures. It is possible that some BF events had FI signatures at an earlier phase than observed, or that they lack dense CSM around the progenitor. Within 2 days after explosion, 8 out of 11 SNe in our sample are either BF events or show FI signatures. Interestingly, we found that 19 out of 21 SNe brighter than an absolute magnitude $M_R=-18.2$ belong to the FI or BF groups, and that all FI events peaked above $M_R=-17.6$ mag, significantly brighter than average SNe~II.

The quality factors were measured at wavelengths of 1.56 μm and 4.58 μm. The impacts of fabrication technique, impurities, multiphonon absorption and surface water are investigated. It is found that MgF2 resonators have room temperature Q factor of $8.3\times 10^6$ at wavelength of 4.58 μm, limited by multiphonon absorption.

description: We propose a covariant ghost-free unimodular $F(R)$ gravity theory, which contains a three-form field and study its structure using the analogy of the proposed theory with a quantum system which describes a charged particle in uniform magnetic field. Newton's law in non-covariant unimodular $F(R)$ gravity as well as in unimodular Einstein gravity is derived and it is shown to be just the same as in General Relativity. The derivation of Newton's law in covariant unimodular $F(R)$ gravity shows that it is modified precisely in the same way as in the ordinary $F(R)$ theory. We also demonstrate that the cosmology of a Friedmann-Robertson-Walker background, is equivalent in the non-covariant and covariant formulations of unimodular $F(R)$ theory.
Von emsigen Ameisen und schlafenden Löwen. Zu ›narratio‹ und ›moralisatio‹ im ›Reinhart Fuchs‹

description: Anhand der Ameisenhandlung untersucht der Beitrag das Verhältnis von narratio und moralisatio im Reinhart Fuchs. Von der positiven moralischen Aufladung, den führerlosen Gesellschaften sowie der enormen Stärke der Ameisen ausgehend, wird verfolgt, wie das Tierepos die Ameisen und ihren Herrn im Kontrast zum Löwenkönig zunächst als Exempel für unbedingte soziale Loyalität und, unter Rückgriff auf Heldenepik und Heroik, für aufopfernden Heldenmut aufbaut. Am Ende jedoch bricht der Text mit diesem Ideal, da der Ameisenherr sich letztlich doch als eigennützig und als anfällig für Reinharts List erweist. Die aufgezeigten narrativen Verfahren bewirken so die völlige Auflösung moralischer Idealität.

description: We analyze the cusp anomalous dimension in the (leading) ladder limit of $\mathcal N=4$ SYM and present new results for its higher-order perturbative expansion. We study two different limits with respect to the cusp angle $ϕ$. The first is the light-like regime where $x = e^{i\,ϕ}\to 0$. This limit is characterised by a non-trivial expansion of the cusp anomaly as a sum of powers of $\log x$, where the maximum exponent increases with the loop order. The coefficients of this expansion have remarkable transcendentality features and can be expressed by products of single zeta values. We show that the whole logarithmic expansion is fully captured by a solvable Woods-Saxon like one-dimensional potential. From the exact solution, we extract generating functions for the cusp anomaly as well as for the various specific transcendental structures appearing therein. The second limit that we discuss is the regime of small cusp angle. In this somewhat simpler case, we show how to organise the quantum mechanical perturbation theory in a novel efficient way by means of a suitable all-order Ansatz for the ground state of the associated Schrödinger problem. Our perturbative setup allows to systematically derive higher-order perturbative corrections in powers of the cusp angle as explicit non-perturbative functions of the effective coupling. This series approximation is compared with the numerical solution of the Schrödinger equation to show that we can achieve very good accuracy over the whole range of coupling and cusp angle. Our results have been obtained by relatively simple techniques. Nevertheless, they provide several non-trivial tests useful to check the application of Quantum Spectral Curve methods to the ladder approximation at non zero $ϕ$, in the two limits we studied.

description: Compositionality and process equivalence are both standard concepts of process algebra. Compositionality means that the behaviour of a compound system relies only on the behaviour of its components, i.e. there is no emergent behaviour. Process equivalence means that the explicit statespace of a system takes a back seat to its interaction patterns: the information that an environment can obtain though interaction. Petri nets are a classical, yet widely used and understood, model of concurrency. Nevertheless, they have often been described as a non-compositional model, and tools tend to deal with monolithic, globally-specified models. This tutorial paper concentrates on Petri Nets with Boundaries (PNB): a compositional, graphical algebra of 1-safe nets, and its applications to reachability checking within the tool Penrose. The algorithms feature the use of compositionality and process equivalence, a powerful combination that can be harnessed to improve the performance of checking reachability and coverability in several common examples where Petri nets model realistic concurrent systems.

description: We report results of a spectral and timing analysis of the poorly studied transient X-ray pulsar 2S 1553-542 using data collected with the NuSTAR and Chandra observatories and the Fermi/GBM instrument during an outburst in 2015. Properties of the source at high energies (>30 keV) are studied for the first time and the sky position had been essentially improved. The source broadband spectrum has a quite complicated shape and can be reasonably described by a composite model with two continuum components - a black body emission with the temperature about 1 keV at low energies and a power law with an exponential cutoff at high energies. Additionally an absorption feature at $\sim23.5$ keV is discovered both in phase-averaged and phase-resolved spectra and interpreted as the cyclotron resonance scattering feature corresponding to the magnetic field strength of the neutron star $B\sim3\times10^{12}$ G. Based on the Fermi/GBM data the orbital parameters of the system were substantially improved, that allowed us to determine the spin period of the neutron star P = 9.27880(3) s and a local spin-up $\dot P \simeq -7.5\times10^{-10}$ s s$^{-1}$ due to the mass accretion during the NuSTAR observations. Assuming accretion from the disk and using standard torque models we have estimated the distance to the system $d=20\pm4$ kpc.

description: The propagation of a surface plasmon-polariton along a stack of doped graphene sheets is considered. This auxiliary problem is used to discuss: (i) the scattering of such a mode at an interface between the stack and the vacuum; (ii) the scattering at an interface where there is a sudden change of the electronic doping. The formalism is then extended to the {\it barrier problem}. In this system rich physics is found for the plasmonic mode, showing: total reflection, total transmission, Fabry-Pérot oscillations, and coupling to photonic modes.

description: We study the problem of generating, ranking and unranking of unlabeled ordered trees whose nodes have maximum degree of $Δ$. This class of trees represents a generalization of chemical trees. A chemical tree is an unlabeled tree in which no node has degree greater than 4. By allowing up to $Δ$ children for each node of chemical tree instead of 4, we will have a generalization of chemical trees. Here, we introduce a new encoding over an alphabet of size 4 for representing unlabeled ordered trees with maximum degree of $Δ$. We use this encoding for generating these trees in A-order with constant average time and O(n) worst case time. Due to the given encoding, with a precomputation of size and time O(n^2) (assuming $Δ$ is constant), both ranking and unranking algorithms are also designed taking O(n) and O(nlogn) time complexities.

description: Contexto: El canal lumbar estrecho es una entidad prevalente en población adulta, siendo la principal causa de cirugía en pacientes mayores de 60 años. Se han utilizado índices de funcionalidad como el Oswestry Disability Index (ODI) para evaluación de pacientes al momento del diagnóstico y posterior a realización de intervenciones terapéuticas; a pesar que en el Hospital Universitario del Caribe se evalúan e intervienen pacientes con canal lumbar estrecho, no hay estudios que midan el impacto de dichas intervenciones en la calidad de vida de las personas con estas patologías. Objetivo: comparar los resultados funcionales de los pacientes intervenidos quirúrgicamente por diagnóstico de canal lumbar estrecho en el Hospital Universitario del Caribe, mediante la aplicación pre y posquirúrgica de la escala de Oswestry. Metodología: estudio observacional descriptivo, prolectivo, que se basó en la medición prequirúrgica del ODI reportada en las historias clínicas, se midieron variables clínicas relacionadas con el tipo y nivel de afección del canal lumbar, tipo y número de procedimientos quirúrgicos realizados y valoración posoperatoria del ODI. Se comparó la puntuación ODI general y estratificado por presencia de listesis y numero de procedimientos, se usaron las pruebas de Wilcoxon y la U de Mann Whitney, un valor p <0,05 fue considerado estadísticamente significativo. Resultados: se analizaron 25 pacientes con mediana de edad de 51 años, el 52% fueron mujeres, en 56% se realizaron tres procedimientos discectomía, laminectomía y artrodesis.

»Der Mensch ist zwar ein Mensch, und folglich keine Maus«. Zum Verhältnis von ›moralisatio‹ und Witzprinzip in Daniel Stoppes Fabel ›Die Maus in der Falle‹
Creators: name: Blum, Stephanie

description: Der Aufsatz widmet sich den bislang in der germanistischen Forschung vernachlässigten Fabeln Daniel Stoppes. Anhand der Fabel ‚Die Maus in der Falle‘ werden die Besonderheiten ihrer ausschweifenden narratio herausgestellt, die sich durch eine ausgedehnte Handlungsstruktur, erzählerische Beschreibungen und Bewertungen sowie Anspielungen auf tradierte Symbole auszeichnet. Elemente der Gelehrtensatire in Auseinandersetzung mit der Stoa und die dadurch erzeugte Ironie machen das Verhältnis zur moralisatio problematisch. Stoppes Fabeln knüpfen über das Witzprinzip an die französische Fabeltradition an und erleben im Kontext der kurz darauf erscheinenden deutschsprachigen Fabeltheorien eine Abwertung.

description: Das Missverhältnis von Erzählung und moralisierendem Epimythion in mittelhochdeutschen Verserzählungen (oft ,Mären‘ genannt) wurde in der Forschung öfters thematisiert. Der Artikel stellt dar, dass Friktionen zwischen narratio und moralisatio in diesen Texten nicht allein ein Untersuchungsfeld für Erzählforscher sind, sondern mindestens ebenso philologische, kodikologische und überlieferungsgeschichtliche Komponenten beinhalten, die in bzw. vor einem ersten Interpretationsschritt betrachtet werden sollten. In vier Durchgängen werden anhand verschiedener kurzer Verserzählungen des Spätmittelalters sowie des ,Eulenspiegel‘ Aporien des Verhältnisses von Erzählung und Deutung dargestellt, wobei unter anderem deren faktische Untrennbarkeit deutlich wird.

Time evolution of decay for purely absorptive potentials: The effect of spectral singularities

description: We consider an analytical approach that involves the complex poles of the propagator to investigate the effect due to the lack of time reversal invariance on the time evolution of decay for purely absorptive potentials. We find that the choice of the initial state may change the exponential decaying regime into a nonexponential oscillatory behavior at time scales of the order of a lifetime of the system. We illustrate this effect for a spectral singularity corresponding to a purely imaginary delta-shell potential.

description: In this paper, we develop the Chaplygin reducing multiplier method; using this method, we obtain a conformally Hamiltonian representation for three nonholonomic systems, namely, for the nonholonomic oscillator, for the Heisenberg system, and for the Chaplygin sleigh. Furthermore, in the case of an oscillator and the nonholonomic Chaplygin sleigh, we show that the problem reduces to the study of motion of a mass point (in a potential field) on a plane and, in the case of the Heisenberg system, on the sphere. Moreover, we consider an example of a nonholonomic system (suggested by Blackall) to which one cannot apply the reducing multiplier method.
