description: The impact of the El Niño-Southern Oscillation (ENSO) on the extratropics is investigated in an idealized, reduced-order model that has a tropical and an extratropical module. Unidirectional ENSO forcing is used to mimick the atmospheric bridge between the tropics and the extratropics. The variability of the coupled ocean-atmosphere extratropical module is then investigated through the analysis of its pullback attractors (PBAs). This analysis focuses on two types of ENSO forcing generated by the tropical module, one periodic and the other aperiodic. For a substantial range of the ENSO forcing, two chaotic PBAs are found to coexist for the same set of parameter values. Different types of extratropical low-frequency variability are associated with either PBA over the parameter ranges explored. For periodic ENSO forcing, the coexisting PBAs exhibit only weak nonlinear instability. For chaotic forcing, though, they are quite unstable and certain extratropical perturbations induce transitions between the two PBAs. These distinct stability properties may have profound consequences for extratropical climate predictions: in particular, ensemble averaging may no longer help isolate the low-frequency variability signal.

description: We propose a new method in the spectral analysis of noisy time-series data for damped oscillators. From the Jacobi three terms recursive relation for the denominators of the Padé Approximations built on the well-known Z-transform of an infinite time-series, we build an Hilbert space operator, a J-Operator, where each bound state (inside the unit circle in the complex plane) is simply associated to one damped oscillator while the continuous spectrum of the J-Operator, which lies on the unit circle itself, is shown to represent the noise. Signal and noise are thus clearly separated in the complex plane. For a finite time series of length 2N, the J-operator is replaced by a finite order J-Matrix J_N, having N eigenvalues which are time reversal covariant. Different classes of input noise, such as blank (white and uniform), Gaussian and pink, are discussed in detail, the J-Matrix formalism allowing us to efficiently calculate hundreds of poles of the Z-transform. Evidence of a universal behaviour in the final statistical distribution of the associated poles and zeros of the Z-transform is shown. In particular the poles and zeros tend, when the length of the time series goes to infinity, to a uniform angular distribution on the unit circle. Therefore at finite order, the roots of unity in the complex plane appear to be noise attractors. We show that the Z-transform presents the exceptional feature of allowing lossless undersampling and how to make use of this property. A few basic examples are given to suggest the power of the proposed method.

description: Problématique : La dysphagie, symptôme signant la présence de troubles de la déglutition (TD) est une complication majeure des accidents vasculaires cérébraux (AVC) survenant dans 29-64% des cas. Les TD affectent la capacité de l’individu à couvrir ses besoins hydriques et nutritifs journaliers et mettent en danger la sécurité des voies aériennes supérieures. Objectifs : Déterminer les interventions infirmières d’évaluation et d’accompagnement des patients dysphagiques en phase aiguë d’un AVC ischémique améliorant le pronostic de récupération. Comparer les résultats cliniques des patients ayant bénéficiés de test de dépistage des troubles de la déglutition (tdd) entre une unité spécialisée dans la prise charge des AVC (SU) et une unité régulière non-spécialisée (URn). Méthodes : Les bases de données CINHAL et PubMed ont été utilisées pour la sélection des articles. Ces derniers sont analysés à l’aide de la grille de lecture critique quantitative du Fortin (2010). Les principaux résultats de ces articles sont ici extraits et synthétisés. La théorie « de Novice à Expert » de Patricia Benner comme cadre théorique a permis une mise en perspective des résultats pour le rôle infirmier. Résultats : La synthèse des résultats a permis de faire ressortir 3 thématiques majeures : la formation continue, la qualité des soins au profit de la sécurité du patient, le rôle du leadership infirmier dans l’interprofessionnalité. Discussion : L’actualisation des connaissances des TD (leur dépistage, leur évaluation et les interventions infirmières y afférentes), permet aux infirmières d’assurer la sécurité du patient et de faire preuve de leadership au sein de l’équipe interprofessionnelle. Conclusion : Les TD sont une complication majeure des AVC. Ils entrainent une augmentation de la mortalité, des situations de handicap sévères et un taux d’institutionnalisation élevé. Fournir des moyens et des ressources permettant une implémentation optimale d’outils simples tels que les tdd, permettrait également une implémentation des recommandations sur les 3 thématiques proposées. Cela pourrait avoir un impact puissant sur tous les enjeux liés aux TD post-AVC en phase aiguë.

description: This paper introduces BFEMP, a new approach for monolithically coupling the Material Point Method (MPM) with the Finite Element Method (FEM) through barrier energy-based particle-mesh frictional contact using a variational time-stepping formulation. The fully implicit time integration of the coupled system is recast into a barrier-augmented unconstrained nonlinear optimization problem. A modified line-search Newton's method is adopted to strictly prevent material points from penetrating the FEM domain, ensuring convergence and feasibility regardless of the time step size or the mesh resolutions. The proposed coupling scheme also reduces to a new approach for imposing separable frictional kinematic boundaries for MPM when all nodal displacements in the FEM domain are prescribed with Dirichlet boundary conditions. Compared to standard implicit time integration, the extra algorithmic components associated with the contact treatment only depend on simple point-segment (or point-triangle in 3D) geometric queries which robustly handle arbitrary FEM mesh boundaries represented with codimension-1 simplices. Experiments and analyses are performed to demonstrate the robustness and accuracy of the proposed method.

Lorenzo Lotto and the surgeon's painting : a private commission in the Venetian Provinces
Creators: name: Klebanoff, Randi Paula
Publisher: name: University of British Columbia
Year: 2010

description: Lorenzo Lotto's Madonna and Child with SS Roch and Sebast ian is a private devotional work, originally in the possession of a surgeon in Bergamo. In this thesis, the painting is looked at as a work that incorporates the associations of a traditional form and charges it with iconographically rich layering to suit its particular commission. A critical historiography of the artist and of the painting introduces my work into the context of the received tradition. I look at the patron of the painting, Battista Cucchi, and at the social and political situation in Bergamo in order to establish the contemporary context of the image. The painting is unusual in its composition, with formal and iconographic innovations giving a disconcerting quality to what is at the foundation a traditional Venetian type -the half-length Madonna and Child with saints. Chapter Two discusses the fifteenth-century half-length tradition in Venice, and Chapter Three deals with the new trends in the sixteenth century that transform private devotional painting in the period of Lotto's Bergamo career. Chapter Six explores the complex iconography of the image. Although the resonances of the prototype -miraculous imagery and the Venetian pedigree suited to Lotto's Bergamo patronage - are preserved, the hieratic aspect and traditional form of the Venetian half-length are transformed. Stylistic dissonances and iconographic innovations both underline particular meanings that are stressed. The two plague saints Roch and Sebastian are common in Venetian works and signal a healing context. Their ecstatic expressions and aggressive participation however are unique in this format. They extend their bracket of healing to participate in the devotional iconography of Christ, Roch by echoing the gesture of Christ and Sebastian by stepping forward in a role as alter christus. The prominent and unusual device of the slab conveys the altar/tomb connotations of the conventional parapet in a more overt way, and by seating the Madonna and Child above it, Lotto emphasizes the theme of triumph over death. Simple on the surface, the painting communicates traditional devotional messages of salvation and intercession that are tempered to apply to the surgeon patron.

Exploring Cybersecurity Issues in 5G Enabled Electric Vehicle Charging Station with Deep Learning

description: The surging usage of electric vehicles (EVs) demand the robust deployment of trustworthy electric vehicle charging station (EVCS) with millisecond range latency and massive machine to machine communications where 5G could act. However, 5G suffers from inherent protocols, hardware, and software vulnerabilities that seriously threaten the communicating entities' cyber-physical security. To overcome these limitations in the EVCS system, this paper analyses the impact of False Data Injection (FDI) and Distributed Denial of Services (DDoS) attacks on the operation of EVCS. This work is an extension of our previously published conference paper about the EVCS. As new features, this paper simulates the FDI attack and the syn flood DDoS attacks on 5G enabled remote Supervisory Control and Data Acquisition (SCADA) system that controls the solar photovoltaics (PV) controller, Battery Energy Storage (BES) controller, and EV controller of the EVCS. The attacks make the EVCS system oscillate or shift the DC operating point. The frequency of oscillation, its damping, and the system's resiliency are found to be related to the attacks' intensity and target controller. Finally, we propose the novel stacked Long Short-Term Memory (LSTM) based intrusion detection systems (IDS) solely based on the electrical fingerprint. This model can detect the stealthy cyberattacks that bypass the cyber layer and go unnoticed in the monitoring system with nearly 100% detection accuracy.

description: For the reliability regions to reliably and securely operate the network and for the Independent System Operators to facilitate effective operation of real time energy market, the real time flows of the system need to known. These flows are calculated based on the real time model made from the real time measurements and the static system information. Observability of the system needs to be increased to increase the accuracy of the estimated states, the extend of which determines how efficiency the system can be operated. The presently available methods for placing RTUs are analyzed and areas that need to be improved for applying these methods to a control area under an ISO or reliability region are identified. A practical approach for finding out minimal number of RTUs and their optimal location are proposed. The new approach is implemented and results are given to the transmission owners for implementing the RTU configuration

description: We perform numerical simulations of fast collective neutrino flavor conversions in an one-dimensional box mimicking a system with the periodic boundary condition in one spatial direction and translation symmetry in the other two dimensions. We evolve the system over several thousands of the characteristic timescale (inverse of the interaction strength) with different initial $\barν_e$ to $ν_e$ number density ratios and different initial seed perturbations. We find that small scale structures are formed due to the interaction of the flavor waves. This results in nearly flavor depolarization in a certain neutrino phase space, when averaged over the entire box. Specifically, systems with initially equal number of $ν_e$ and $\barν_e$ can reach full flavor depolarization for the entire neutrino electron lepton number ($ν$ELN) angular spectra. For systems with initially unequal $ν_e$ and $\barν_e$, flavor depolarization can only be reached in one side of the $ν$ELN spectra, dictated by the net neutrino $e-x$ lepton number conservation. Quantitatively small differences depending on the initial perturbations are also found when different perturbation seeds are applied. Our numerical study here provides new insights for efforts aiming to include impact of fast flavor conversions in astrophysical simulations while calls for better analytical understanding accounting for the evolution of fast flavor conversions.

We attribute them to mesoscopic transport in narrow channels across the grain boundary line, occurring in an unusual energy regime. The Thouless energy appears to be the relevant energy scale. Possible implications on the understanding of coherent transport of quasiparticles in HTS and of the dissipation mechanisms are discussed.

The Discursive Construction of Chinese Nationalism in Online Communities: Taking Douban as an Example

Publisher: name: University of Chicago
Year: 2021
Subjects: subject: Chinese nationalism
subject: social media
subject: expressive forms
subject: identity

description: Chinese nationalism has been widely explored by scholars for good reason. With the advent of the information age, people gradually gave up taking up the street and begun to occupy the social media to realize their political goals. Internet became the main battlefield of Chinese nationalism shortly. Yet little is known about those “cybernationalists” and their expressive forms in different social situations. This study therefore shifts the gaze from the inquiry about “what Chinese nationalism is” to the exploration that social characters or figures (e.g., cybernationalists) and their qualities are enregistered in forms of talk and how netizens rejected or accepted the personae predefined for them. By examining the uptakes of “Little Pink” (xiao fenhong) [小粉紅] and narratives of the Kimchi incident on Douban, a social media website of China, I contribute to the scholarly discussion a case which suggests that today’s Chinese nationalism is more recounted as continuous interactions among those engaging each other on the digital sites than a unidimensional relationship between Chinese people and the Party.

Magnetic fields in elliptical galaxies: Using the Laing-Garrington effect in radio galaxies and polarized emission from background radio sources

Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Magnetic fields in elliptical galaxies are poorly constrained due to a lack of significant synchrotron emission from them. This paper explores properties of magnetic fields in ellipticals via two methods. First, we exploit the Laing-Garrington effect (asymmetry in the observed polarization fraction between radio galaxy jets) for 57 galaxies with redshifts up to $0.5$. We use the differences in polarization fraction and rotation measure between the jet and counterjet to estimate the small- and large-scale magnetic fields in and around ellipticals (including their circumgalactic medium). We find that the small-scale field (at scales smaller than the driving scale of turbulence, approximately $300~{\rm pc}$) lies in the range $0.1~\text{--}~2.75~μ{\rm G}$. The large-scale field (at scales of $100~{\rm kpc}$) is an order of magnitude smaller than the small-scale field. In the second method, we cross-match the Faraday rotation measures (RM) of a few hundred (out of $3098$) extragalactic radio sources with galaxy catalogs to explore the effect of the number and morphology of intervening galaxies on the observed RM distribution. We use both Gaussian and non-Gaussian functions to describe the RM distribution and derive its statistical properties. Finally, using the difference in the observed polarization fraction between the intervening spirals and ellipticals, we estimate the small-scale magnetic fields at the center of ellipticals to be $\sim6~μ{\rm G}$. Both methods with different observations and analysis techniques give magnetic field strengths consistent with previous studies ($\leq10μ{\rm G}$), and the results can be used to constrain dynamo theories and galaxy evolution simulations.

Optical properties and photoreactivity of the Green  Fluorescent Protein. A theoretical study.
Creators: name: Tenuta, Silvia
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: This PhD thesis focuses on the theoretical analysis of Green Fluorescent Protein (GFP) photochemistry. GFP peculiar properties make it and its mutants ideal noninvasive markers in living cells, suited for numerous applications, like reporter of gene expression, cell lineage tracer, measure of protein-protein interactions, signaling and trafficking in cellular systems  and useful in many fields, such as molecular biology, biotechnology or medicine. One of the most interesting aspects in the study of the GFPs is the analysis of their photophysics and photochemistry in order to improve the efficiency and efficacy of their applications. In this work we have performed an in-depth analysis of GFP absorption, combining DFT and TD-DFT with ONIOM method, in order to investigate the relation among structure, optical properties and GFP functionality. In addition, evaluating GFP photoinduced behaviour, we have focused our attention on the proton shuttle triggered by excitation and we have tried to shed light on this complex issue proposing an hypothesis for its mechanism. We have reached a fine control on GFPs absorption, a clear  understanding of the photophysics and photochemistry changes induced by the molecular environment and a deep omprehension of the relation between GFP structure and properties. These results allow to achieve highly moduled design of  fluorescence and to maximize the potentiality of these proteins and use them in a more effective way to improve bioimaging techniques and nanotechnology.

description: Mehr als 30 Jahre nach dem Tod James Baldwins haben die gesellschaftspolitischen Analysen des afro‐amerikanischen Autors nach wie vor Gewicht. Die umsichtige Bestimmtheit seiner Standpunkte aus der Zeit vor, während oder nach der Hochphase der US‐amerikanischen Bürgerrechtsbewegung heute zu lesen, macht aktuelle politische Kämpfe um Ressourcen, Macht oder Deutungshoheit nicht nur verständlicher, sondern auch erträglicher. In seinen Essays setzt Baldwin seine eigenen Erfahrungen stets in Bezug zu strukturellen Fragen, stellt seinen eigenen Blick anderen zur Verfügung, um ihnen zu einem tieferen, differenzierteren Verständnis von Macht, Rassismus und Unterdrückung zu verhelfen. Afrika steht nicht im Zentrum von Baldwins Werk; es ist allerdings durchzogen von Bezügen auf den Kontinent, auf seine Bewohner_innen wie auch auf die Imagination ‚Afrika‘. Beeinflusst von Begegnungen mit Afrikaner_innen in Paris, dem Einwirken afrikabezogener Diskurse auf afro‐amerikanische Debatten und Selbstverständnisse, seinen Afrikareisen oder der Verbreitung problematischer Afrikabilder in den USA reflektiert Baldwin die Unbestimmtheit und Unbestimmbarkeit seiner Herkunft, die Rolle Afrikas innerhalb seiner Identität und die Verwobenheit von Geschichte und Gegenwart. Auf den folgenden Seiten greife ich einige der Stränge auf, die Baldwin in seinem Werk in Bezug auf Afrika entwirft, um ihn dadurch (nicht nur) einem afrikawissenschaftlich interessierten Publikum vertrauter zu machen.

description: Strong gravitational lensing by galaxies in MOdified Newtonian Dynamics (MOND) has until now been restricted to spherically symmetric models. These models were able to account for the size of the Einstein ring of observed lenses, but were unable to account for double-imaged systems with collinear images, as well as four-image lenses. Non-spherical models are generally cumbersome to compute numerically in MOND, but we present here a class of analytic non-spherical models that can be applied to fit double-imaged and quadruple-imaged systems. We use them to obtain a reasonable MOND fit to ten double-imaged systems, as well as to the quadruple-imaged system Q2237+030 which is an isolated bulge-disc lens producing an Einstein cross. However, we also find five double-imaged systems and three quadruple-imaged systems for which no reasonable MOND fit can be obtained with our models. We argue that this is mostly due to the intrinsic limitation of the analytic models, even though the presence of small amounts of additional dark mass on galaxy scales in MOND is also plausible.

description: By applying the idea of parafermionic clustering to composite bosons with positive as well as negative flux, a new series of trial wavefunctions to describe fractional quantum Hall states is proposed. These non-Abelian states compete at filling factors k/(3k +/- 2) with other ground states like stripes or composite fermion states. These two series contain all the states recently discovered by Pan et al. [Phys. Rev. Lett. 90, 016801 (2003)] including the even denominator cases. Exact diagonalization studies on the sphere and torus point to their possible relevance for filling factors 3/7, 3/11, and 3/8.

Une thérapie complémentaire : l’auriculopuncture, à travers le protocole NADA, est utilisée spécifiquement pour les dépendances aux substances, dont l’alcool. Dans le canton de Vaud, le protocole NADA est largement utilisé dans les services d’alcoologie. Cependant, la plupart des études démontrent une inefficacité de l’auriculopuncture ce qui est paradoxal au vu de la pratique dans plusieurs pays. Objectif : La question de recherche est : quelle est la pertinence d’une intervention d’auriculopuncture, réalisée par une infirmière, sur un patient en phase de sevrage d’une dépendance alcoolique ? Méthode : Six articles scientifiques ont été sélectionnés sur les bases de données PubMed et CINAHL. Ensuite, ces études ont été analysées à l’aide des grilles de lecture critique de Fortin (2010). La théorie de la gestion des symptômes a permis de synthétiser les résultats de ces six articles. Résultats : Une diminution des symptômes du sevrage alcoolique et une diminution de la consommation d’alcool ont été relevés malgré une différence de résultats insignifiants entre l’auriculopuncture et les groupes contrôles qui sont, la plupart du temps, une autre thérapie complémentaire également efficace pour cette problématique. Conclusion : Plusieurs thérapies complémentaires diminuent les symptômes de sevrage liés à l’alcool. La comparaison entre ces thérapies et l’auriculopuncture est donc insignifiante. L’auriculopuncture est efficace dans la diminution de la consommation de l’alcool en agissant sur les symptômes de sevrage, le contexte et la qualité de vie.

Six articles datant de 2010 à 2017, ayant un devis qualitatif, ont été sélectionnés grâce à l’ajout de critères d’inclusions et d’exclusions. Résultats : L’expérience d’attente d’une transplantation rénale est marquée par diverses formes d’incertitude. Le soutien des proches et du personnel infirmier est important durant cette attente. L’information est principalement utilisée, par les patients, comme stratégie d’adaptation pour réduire ou maintenir l’incertitude. Discussion : L’apport d’information est un élément clé dans la prise en charge du patient. Le suivi de ces patients doit se faire en interdisciplinarité. Les soignants doivent améliorer leurs capacités à reconnaître et à répondre de manière appropriée aux préoccupations des patients. Ils doivent s’engager dans une discussion ouverte et authentique avec les patients à propos de la transplantation et individualiser la prise en charge selon les besoins du patient.

We analyze the applicability of simple two-level Landau-Zener model to describe the evolution of the probability amplitudes in this realistic system. We show that the Landau-Zener model works very well when it is viewed in the adibatic basis, but it is not as robust in the diabatic basis.

description: We measure the time-dependent CP asymmetry in B0 --> K_S0 pi0 gamma decays for two regions of K_S0-pi0 invariant mass, m(K_S0 pi0), using the final BABAR data set of 467 x 10^6 BBbar pairs collected at the PEP-II e+e- collider at SLAC. We find 339 +/- 24 B0 --> K*0 gamma candidates and measure S_{K* gamma} = -0.03 +/- 0.29 +/- 0.03 and C_{K* gamma} = -0.14 +/- 0.16 +/- 0.03. In the range 1.1 < m(K_S0 pi0) < 1.8 GeV/c^2 we find 133 +/- 20 B0 --> K_S0 pi0 gamma candidates and measure S_{K_S0 pi0 gamma} = -0.78 +/- 0.59 +/- 0.09 and C_{K_S0 pi0 gamma} = -0.36 +/- 0.33 +/- 0.04. The uncertainties are statistical and systematic, respectively.

description: In den späten 1990er‐Jahren haben deutsche und österreichische TV‐Produktionsfirmen Afrika als Kulisse für einfach konzipierte Unterhaltungsfilme entdeckt. Wie am Fließband wurden Jahr für Jahr neue Publikumshits mit generischen Titeln wie „Mein Traum von Afrika“, „Ausgerechnet Afrika“, „Eine Liebe in Afrika“ oder „Afrika ruft nach dir“ gedreht, die seither in Dauerschleife auf den deutschsprachigen Kanälen laufen. Im Österreichischen Rundfunk (ORF) sind das rund dreißig verschiedene, zum Teil mit öffentlichen Geldern koproduzierte Filme. Vorliegender Beitrag macht deutlich, wie problematisch die darin imaginierten Afrikabilder auch mit Blick auf schwarze bzw. nicht‐weiße Minderheiten in Österreich und Deutschland sind. Er basiert auf einer kombinierten kommunikationswissenschaftlichen Rezeptions‐ und Inhaltsanalyse, die Zusammenhänge zwischen populären Fernsehbildern, Rezeptionsweisen und gesellschaftlichen Wirklichkeiten offenlegt. Der Beitrag verdeutlicht die Ergebnisse der Studie exemplarisch anhand der filmischen Inszenierung von Handlungsorten in Afrika und in Europa, der damit verbundenen Konstruktion von Fremdheit (Othering) mit narrativen und technischen Mitteln sowie der Verhandlung des Gezeigten durch sein Publikum.

description: Very thin (1.2-2.5nm) self-assembled organic dielectric monolayers have been integrated into organic thin-film diode to achieve electrical characteristics. These dielectrics are fabricated by self-assembling deposition, resulting in smooth, strongly adherent, thermally stable, organosiloxane thin films having interesting electrical capacitances (around 150 nF cm-2 at -3V) and insulating properties (leakage current densities around 10-5 A cm2 at -1V).

description: Contexte : La prostitution, phénomène mondial, est soumise à des facteurs de vulnérabilité dont une exposition particulière aux IST et au VIH. La prévention infirmière a un rôle à jouer auprès de cette population dont les prises de risque sexuelles sont fréquentes. Objectif : Déterminer le rôle de la prévention infirmière concernant les IST et le VIH auprès des TdS. Méthode : Deux bases de données, PubMED et CINAHL ont été consultées et ont permis de retenir six études, publiées entre 2008 et 2018. Après les avoir soumises aux critères de sélection, elles ont été analysées grâce aux grilles de lecture critique de Fortin (2010). Les résultats ont été exposés dans des tableaux, résumés puis synthétisés à l’aide du cadre conceptuel de Roy (1984). Résultats : Plusieurs facteurs tels que le degré de connaissance des IST/VIH, le statut migratoire, la précarité et la violence ont un impact majeur sur le comportement sexuel à risque des TdS et donc sur la transmission des infections, qui sont fréquentes. De plus, les services de soins sont peu utilisés par les TdS. Conclusion : La prévention et la prise en charge infirmière actuelle est insuffisante mais nécessaire afin de diminuer les prises de risque et ainsi les transmissions d’infections.

description: Introduction : L’estime de soi est un indicateur de la qualité de vie chez les personnes âgées. De plus, c’est un point important des modèles de vieillissement réussis. Il est également connu que dès l’âge de septante ans, l’estime de soi commence à diminuer. La musculation possède un grand nombre d’effets positifs avérés lors du vieillissement, tant sur l’aspect physique, psychologique, que cognitif. Objectif : L’objectif de ce travail est d’investiguer la manière dont les personnes de plus de septante ans ressentent les effets de la musculation sur leur estime de soi. Méthode : Suivant une approche qualitative, les auteurs ont mené des entretiens avec cinq personnes de plus de septante ans pratiquant déjà de la musculation avec charge additionnelle dans un fitness. Des entretiens semi-directifs ont été menés en individuel de manière à pouvoir les retranscrire et procéder à une analyse thématique. Résultats : À l’aide de l’analyse thématique, les auteurs ont ressorti quatre thèmes qui sont : objectifs et capacités physiques, vieillissement, facteurs sociaux extrinsèques et bien-être global. Conclusion : Les auteurs ont conclu que la musculation avec charge additionnelle à des effets perçut sur les composantes de l’estime de soi principalement au travers du bien-être physique et psychique, de l’aspect social et de l’image de soi. Cependant un certain nombre de ces effets ne peuvent pas être attribués uniquement au renforcement musculaire et peuvent être obtenus par d’autres activités physiques.

description: Im Jahr 2005 erschien der Roman Beasts of No Nation von Uzodinma Iweala, in welchem die Geschichte von Agu erzählt wird, einem Jungen in einem nicht benannten afrikanischen Land, der zum Kindersoldaten gemacht wird. Im Jahr 2009 wurde der Stoff unter dem Titel LITTLE ENEMYz (Eberhard Petschinka) als Hörspiel für ein deutschsprachiges Publikum adaptiert und weitere sechs Jahre später für ein internationales Publikum als Film (Beasts of No Nation, Cary Joji Fukunaga). Dieser Aufsatz analysiert die drei Werke unter Berücksichtigung des Medienwechsels und der unterschiedlichen angesprochenen Publika. Anhand der Auseinandersetzung mit der Erzählstimme, der Herstellung des Settings und der inhaltlichen Gestaltung der jeweiligen Enden, stellt der Aufsatz heraus wie mit den semiotischen Verschiebungen auch semantische einhergehen.

description: Early detection is crucial to prevent the progression of Alzheimer's disease (AD). Thus, specialists can begin preventive treatment as soon as possible. They demand fast and precise assessment in the diagnosis of AD in the earliest and hardest to detect stages. The main objective of this work is to develop a system that automatically detects the presence of the disease in sagittal magnetic resonance images (MRI), which are not generally used. Sagittal MRIs from ADNI and OASIS data sets were employed. Experiments were conducted using Transfer Learning (TL) techniques in order to achieve more accurate results. There are two main conclusions to be drawn from this work: first, the damages related to AD and its stages can be distinguished in sagittal MRI and, second, the results obtained using DL models with sagittal MRIs are similar to the state-of-the-art, which uses the horizontal-plane MRI. Although sagittal-plane MRIs are not commonly used, this work proved that they were, at least, as effective as MRI from other planes at identifying AD in early stages. This could pave the way for further research. Finally, one should bear in mind that in certain fields, obtaining the examples for a data set can be very expensive. This study proved that DL models could be built in these fields, whereas TL is an essential tool for completing the task with fewer examples.
Discovery of superstrong, fading, iron line emission and double-peaked Balmer lines of the galaxy SDSSJ0952+2143 - the light echo of a huge flare

description: We report the discovery of superstrong, fading, high-ionization iron line emission in the galaxy SDSSJ095209.56+214313.3 (SDSSJ0952+2143 hereafter), which must have been caused by an X-ray outburst of large amplitude. SDSSJ0952+2143 is unique in its strong multiwavelength variability; such a broadband emission-line and continuum response has not been observed before. The strong iron line emission is accompanied by unusual Balmer line emission with a broad base, narrow core and double-peaked narrow horns, and strong HeII emission. These lines, while strong in the SDSS spectrum taken in 2005, have faded away significantly in new spectra taken in December 2007. Comparison of SDSS, 2MASS, GALEX and follow-up GROND photometry reveals variability in the NUV, optical and NIR band. Taken together, these unusual observations can be explained by a giant outburst in the EUV--X-ray band, detected even in the optical and NIR. The intense and variable iron, Helium and Balmer lines represent the ``light echo'' of the flare, as it traveled through circumnuclear material. The outburst may have been caused by the tidal disruption of a star by a supermassive black hole. Spectroscopic surveys such as SDSS are well suited to detect emission-line light echoes of such rare flare events. Reverberation-mapping of these light echoes can then be used as a new and efficient probe of the physical conditions in the circumnuclear material in non-active or active galaxies.
