description: Titre : Les interventions de l’infirmière scolaire dans l’accompagnement d’enfants âgés de 6 à 12 ans, atteints de surpoids ou d’obésité, en considérant les croyances et perceptions des parents sur l’alimentation. Contexte : L’épidémie de surpoids et d’obésité infantile est en augmentation au niveau mondial. Prise en charge de cette problématique en milieu scolaire. Objectifs : Déterminer les interventions infirmières auprès des familles d’enfants de 6 à 12 ans, atteints de surpoids ou d’obésité. Méthode : Utilisation de 3 bases de données : CINHAL, PubMed/Medline et ERIC. 11 articles datant de 2005 à 2012 sont retenus pour la recension des écrits. Ces articles traitant du surpoids et de l’obésité infantile correspondent au domaine infirmier et touchent les parents d’enfants d’âge scolaire. Les données des articles ont été résumées puis confrontées entre elles. Résultats : Il existe différentes manières d’intervenir dans l’accompagnement de l’enfant atteint de surpoids ou d’obésité. L’axe à privilégier est de centrer les actions sur les parents afin de favoriser une prise de conscience de la problématique, en vue de réduire le taux de surpoids et d’obésité. En conséquence, une approche bio-psycho-socio-culturelle, basée sur des outils issus de données probantes, améliorerait le partenariat avec les familles. Conclusion : Agir sur les parents risque de compromettre la relation de confiance établie entre l’infirmière et la famille, car cette approche peut remettre en cause l’éducation des enfants. Or, il existe des stratégies d’intervention permettant de réduire cet obstacle.

description: Modified gravity theories with geometry - matter coupling, in which the action is an arbitrary function of the Ricci scalar and the matter Lagrangian ($f\left(R,L_m\right)$ gravity), and of the Ricci scalar and of the trace of the matter energy-momentum tensor ($f(R,T)$ gravity), respectively, have the intriguing property that the divergence of the matter energy - momentum tensor is nonzero. In the present paper, by using the formalism of open thermodynamic systems, we interpret the generalized conservation equations in these gravitational theories from a thermodynamic point of view as describing irreversible matter creation processes, which could be validated by fundamental particle physics. Thus particle creation corresponds to an irreversible energy flow from the gravitational field to the created matter constituents, with the second law of thermodynamics requiring that space-time transforms into matter. The equivalent particle number creation rates, the creation pressure and the entropy production rates are obtained for both $f\left(R,L_m\right)$ and $f(R,T)$ gravity theories. The temperature evolution laws of the newly created particles are also obtained. In the case of the $f(R,T)$ gravity theory the open irreversible thermodynamic interpretation of a simple cosmological model is presented in detail. It is also shown that due to the geometry--matter coupling, during the cosmological evolution a large amount of comoving entropy could be produced.

description: Problématique : La douleur chronique est un problème bien réel chez les personnes âgées. Elle affecte les dimensions physiologique, psychique, sociale et spirituelle ainsi qu’engendre de nombreuses conséquences sur la qualité de vie. Les polypathologies affectant cette population, l’amène à la prise de nombreux médicaments, ce qui engendre entre autre, divers effets secondaires. But : L’objectif de ce travail est d’évaluer l’efficacité des interventions non-pharmacologiques que peuvent utiliser les infirmières afin de diminuer l’intensité de la douleur des personnes âgées ; et si celles-ci permettent une diminution de la prise d’antalgiques. Méthode : La recherche documentaire sur les bases de données CINAHL et PubMed a abouti à la sélection de cinq articles scientifiques. Cette dernière a été réalisée à l’aide de descripteurs correspondant aux interventions de confort, à savoir le massage, la musicothérapie et l’imagerie guidée. Des limites ainsi que des critères d’inclusion et d’exclusion ont été déterminés afin de sélectionner les articles. Résultats : Les études analysées démontrent que le massage, la musicothérapie et l’imagerie guidée diminuent significativement la douleur. Seule une étude a répertorié les antalgiques et montré une diminution de leur prise quotidienne. Conclusion : Les interventions de confort sont des mesures infirmières efficientes, simples d’utilisation, non-invasives et complémentaires au traitement pharmacologique dans la gestion de la douleur chronique chez la personne âgée. La recherche quant à leur impact sur la prise d’antalgiques nécessite d’être poursuivie.

description: Objectif : Ce travail de Bachelor a pour but d'explorer le lien qu'il existe entre le co-dodo et la MSN. Ces informations permettront d'élaborer une discussion sur le rôle de la sage-femme dans les recommandations spécifiques liées à la pratique du co-dodo. Méthodologie : Cette revue de littérature est fondée sur dix articles sélectionnés dans les bases de données PUBMED et CINHAL. Neuf études quantitatives primaires et une revue de littérature sur les particularités du sommeil du nouveau-né en font partie. Résultats : Le co-dodo est corrélé à une augmentation du risque de MSN. Cependant des biais potentiels peuvent affecter cette relation en ne prenant pas en compte divers paramètres importants. En effet, le co-dodo serait surtout dangereux quand des facteurs se surajoutent. Voici ceux relevés dans nos articles : tabagisme maternel pendant la grossesse et parental en post-partum, l'utilisation d'un matelas mou, de duvets ou d'oreiller à proximité, le sur habillement, le co-dodo hors de la maison ou entre les parents, avec des nouveaux-nés de petit poids, âgé de moins de 3 mois. Afin de permettre aux parents de faire un choix éclairé, en tant que sage-femme il convient de les informer de ces risques. De plus, il est important d'en parler afin que l'environnement de couchage en co-dodo soit réfléchi et le plus sécuritaire possible.

description: Direct collapse black holes (DCBHs) are the leading candidates for the origin of the first supermassive black holes. However, the role of magnetic fields during their formation is still unclear as none of the previous studies has been evolved long enough to assess their impact during the accretion phase. Here, we report the results from a suite of 3D cosmological magneto-hydrodynamic (MHD) simulations which are evolved for 1.6 Myrs comparable to the expected lifetime of supermassive stars (SMSs). Our findings suggest that magnetic fields are rapidly amplified by strong accretion shocks irrespective of the initial magnetic field strength and reach the saturation state. They stabilize the accretion disks and significantly reduce fragmentation by enhancing the Jeans mass in comparison with pure hydrodynamical runs. Although the initial clump masses are larger in MHD runs, the rapid coalescence of clumps in non-MHD cases due to the higher degree of fragmentation results in similar masses. Overall, the central clumps have masses of $\rm 10^5~M_{\odot}$ and the mean mass accretion rates of $\rm \sim 0.1 ~M_{\odot}/yr$ are similar in both MHD and non-MHD cases. The multiplicity of SMSs is significantly reduced in MHD simulations. Such strongly amplified magnetic fields are expected to launch Jets and outflows which may be detected with upcoming radio telescopes.

Temporal cloaking with accelerating wave packets

Publisher: name: arXiv
Year: 2014
Subjects: subject: Optics (physics.optics)

description: We theoretically propose a temporal cloaking scheme based on accelerating wave packets. A part of a monochromatic lightwave is endowed with a discontinuous nonlinear frequency chirp, so that two opposite accelerating caustics are created in space-time as the different frequency components propagate in the presence of dispersion. The light intensity in the interior of this biconvex time gap is negligible, thus concealing the enclosed events. In contrast to previous temporal cloaking schemes, where light propagates successively through two different media with opposite dispersions, accelerating wave packets open and close the cloaked time window continuously in a single dispersive medium. In addition, biconvex time gaps can be tailored into arbitrary shapes and offer a larger suppression of intensity compared to their rhombic counterparts.

description: Session-based recommender systems (SBRSs) have shown superior performance over conventional methods. However, they show limited scalability on large-scale industrial datasets since most models learn one embedding per item. This leads to a large memory requirement (of storing one vector per item) and poor performance on sparse sessions with cold-start or unpopular items. Using one public and one large industrial dataset, we experimentally show that state-of-the-art SBRSs have low performance on sparse sessions with sparse items. We propose M2TRec, a Metadata-aware Multi-task Transformer model for session-based recommendations. Our proposed method learns a transformation function from item metadata to embeddings, and is thus, item-ID free (i.e., does not need to learn one embedding per item). It integrates item metadata to learn shared representations of diverse item attributes. During inference, new or unpopular items will be assigned identical representations for the attributes they share with items previously observed during training, and thus will have similar representations with those items, enabling recommendations of even cold-start and sparse items. Additionally, M2TRec is trained in a multi-task setting to predict the next item in the session along with its primary category and subcategories. Our multi-task strategy makes the model converge faster and significantly improves the overall performance. Experimental results show significant performance gains using our proposed approach on sparse items on the two datasets.

description: A method of simulating the drying process of a soft matter solution with an implicit solvent model by moving the liquid-vapor interface is applied to various solution films and droplets. For a solution of a polymer and nanoparticles, we observe "polymer-on-top" stratification, similar to that found previously with an explicit solvent model. Furthermore, "polymer-on-top" is found even when the nanoparticle size is smaller than the radius of gyration of the polymer chains. For a suspension droplet of a bidisperse mixture of nanoparticles, we show that core-shell clusters of nanoparticles can be obtained via the "small-on-outside" stratification mechanism at fast evaporation rates. "Large-on-outside" stratification and uniform particle distribution are also observed when the evaporation rate is reduced. Polymeric particles with various morphologies, including Janus spheres, core-shell particles, and patchy particles, are produced from drying droplets of polymer solutions by combining fast evaporation with a controlled interaction between the polymers and the liquid-vapor interface. Our results validate the applicability of the moving interface method to a wide range of drying systems. The limitations of the method are pointed out and cautions are provided to potential practitioners on cases where the method might fail.

Comparison of Atmospheric Parameters Determined from Spectroscopy and Photometry for DA White Dwarfs in the Sloan Digital Sky Survey

description: We present a comparative analysis of atmospheric parameters obtained with the so-called photometric and spectroscopic techniques. Photometric and spectroscopic data for 1360 DA white dwarfs from the Sloan Digital Sky Survey (SDSS) are used, as well as spectroscopic data from the Villanova White Dwarf Catalog. We first test the calibration of the ugriz photometric system by using model atmosphere fits to observed data. Our photometric analysis indicates that the ugriz photometry appears well calibrated when the SDSS to AB_95 zeropoint corrections are applied. The spectroscopic analysis of the same data set reveals that the so-called high-log g problem can be solved by applying published correction functions that take into account 3D hydrodynamical effects. However, a comparison between the SDSS and the White Dwarf Catalog spectra also suggests that the SDSS spectra still suffer from a small calibration problem. We then compare the atmospheric parameters obtained from both fitting techniques and show that the photometric temperatures are systematically lower than those obtained from spectroscopic data. This systematic offset may be linked to the hydrogen line profiles used in the model atmospheres. We finally present the results of an analysis aimed at measuring surface gravities using photometric data only.

description: Dans la pratique, nous entendons souvent, de la part des TRM diplômés, que les patientes influencent grandement le positionnement lors des examens mammographiques et, par conséquent, la qualité du cliché. En effet, les aspects morphologiques, (BMI, taille, volume du sein), psychologiques (première mammographie, stress) et physiologiques (douleur) de la patiente au moment de l’examen sont étroitement liés à la réussite des clichés. Le but de ce travail est d’identifier les critères liés à la patiente qui modifient la qualité du cliché mammographique afin de pouvoir, nous l’espérons, améliorer les pratiques lors de la réalisation de ces examens et, ainsi, mieux atteindre les critères de qualité PGMI (Perfect, Good, Moderately Good, Inadequate). Pour effectuer ce travail, nous avons réalisé une enquête de terrain, en distribuant 300 questionnaires dans deux services de radiologie. Après avoir récupéré les questionnaires contenant des informations sur la patiente, nous avons évalué les clichés grâce à la grille d’analyse PGMI et répertorié ces résultats dans l’application Muchacha®. Puis, nous avons croisé ces résultats avec différentes caractéristiques d’ordre morphologique et psychologique des patientes. Globalement, sur l’ensemble des clichés crânio-caudaux, 78% ont obtenu la note « Moderately Good». Pour les clichés médio-latéraux obliques, la note moyenne était « Moderately Good » dans 91% des cas. Les résultats des croisements montrent que les caractéristiques morphologiques ont une forte influence sur la qualité des clichés. Ainsi, le BMI, la taille de la patiente, le volume du sein et sa densité sont les facteurs morphologiques qui peuvent influencer la qualité du cliché. Grâce à une relation de confiance maîtrisée, nous avons pu déduire que l’aspect psychologique n’est, lui, pas un critère qui influence fortement la qualité du cliché.

description: It was shown recently that entanglement of identical particles has a feature called dualism [Phys. Rev. Lett. 110, 140404 (2013)], which is fundamentally connected with quantum indistinguishability. Here we report an experiment that observes the entanglement duality for the first time with two identical photons, which manifest polarization entanglement when labeled by different paths or path entanglement when labeled by polarization states. By adjusting the mismatch in frequency or arrival time of the entangled photons, we tune the photon indistinguishability from quantum to classical limit and observe that the entanglement duality disappears under emergence of classical distinguishability, confirming it as a characteristic feature of quantum indistinguishable particles.

description: Objectifs : Le CTDIvol est un indice de dose mis en place afin d’estimer les doses absorbées lors d’examens au scanner. Cet indice souffre malheureusement d’imprécisions du fait qu’il se base sur des fantômes en plexiglas de 16 ou 32 centimètres de diamètre. Afin d’adapter cet indice CTDIvol, l’AAPM (American Association of Physicists in Medecine) a apporté des facteurs de correction du CTDIvol en fonction des diamètres effectifs du patient pour en obtenir la SSDE (Size Specific Dose Estimates). L’objectif de notre travail était d’apporter des données supplémentaires concernant la modulation de courant, notamment dans les doses délivrées aux organes sur des protocoles abdo-pelviens pédiatriques et adultes. Méthodologie : Afin de mesurer les doses absorbées, nous avons placé des dosimètres thermoluminescents dans les cavités de deux fantômes anthropomorphiques : un modèle adulte de 55 kg et un modèle enfant de 19 kg (environ 5 ans). Les fantômes ont été irradiés comme suit: le fantôme adulte avec un protocole abdo-pelvien adulte et le fantôme enfant avec le même protocole adulte ainsi qu'un protocole pédiatrique. Résultats : Dans une tranche du fantôme adulte, la moyenne des doses absorbées mesurées par nos TLD (13,87 mGy) sont plus proches des valeurs SSDE (13,1 mGy) que des valeurs CTDI (7,12 mGy). L’application du protocole pédiatrique réduit les doses aux organes jusqu'à 30% par rapport à l'usage d'un protocole adulte lorsqu'il s'agit d'un enfant. Conclusion : L’utilisation de la SSDE permet d’estimer de manière plus fiable les doses absorbées lors d’examens CT utilisant la modulation de courant. De plus, cette étude met en évidence l’utilité de la mise en place de protocoles dédiés à la pédiatrie afin de diminuer les doses délivrées aux enfants, grâce notamment à l'abaissement de la tension.

description: Placing a large mass in a large spatial superposition, such as a Schrödinger Cat state is a significant and important challenge. In particular, the large spatial superposition (${\cal O}(10-100)$ $μ$m) of mesoscopic masses ($m\sim {\cal O}(10^{-14} -10^{-15})$ kg) makes it possible to test the quantum nature of gravity via entanglement in the laboratory. To date, the proposed methods of achieving this spatial delocalization are to use wavepacket expansions or quantum ancilla (for example spin) dependent forces, all of whose efficacy reduces with mass. Thus increasing the spatial splitting independent of the mass is an important open challenge. In this paper, we present a method of achieving a mass-independent enhancement of superposition via diamagnetic repulsion from current-carrying wires. We analyse an example system which uses the Stern-Gerlach effect to creating a small initial splitting, and then apply the diamagnetic repulsion method to enhance the superposition size ${\cal O}(400-600)$ $μ$m from an initial modest split of the wavefunction. We provide an analytic and numeric analysis of our scheme.

description: In no other field of astrophysics has the impact of new instrumentation been as substantial as in the domain of exoplanets. Before 1995 our knowledge about exoplanets was mainly based on philosophical and theoretical considerations. The following years have been marked, instead, by surprising discoveries made possible by high-precision instruments. More recently the availability of new techniques moved the focus from detection to the characterization of exoplanets. Next-generation facilities will produce even more complementary data that will lead to a comprehensive view of exoplanet characteristics and, by comparison with theoretical models, to a better understanding of planet formation.

description: Introduction : Les chaussures minimalistes sont la nouvelle tendance en matière de chaussures de course. Beaucoup de coureurs amateurs s’entraînant en chaussures traditionnelles s’essayent à ce type de chaussage alors que leurs effets sont controversés. Malgré la littérature traitant de ce sujet, il n’existe aucune recommandation d’usage à ce jour. Objectif : L’objectif de cette revue est d’observer si la chaussure minimaliste est suffisante à elle seule pour modifier significativement la biomécanique de course du coureur amateur s’entraînant en chaussures traditionnelles. Méthodologie : Des recherches documentaires ont été effectuées sur les bases de données Pubmed, The Cochrane Library et Cinahl au moyen de descripteurs et de mots-clés. Les études répondant à nos critères ont été incluses afin de créer une revue systématique quantitative de type narrative de la littérature. Des références supplémentaires ont également été apportées par les bibliographies des études sélectionnées. Résultats : Trois études ont été retenues. Chacune analyse des paramètres cinématiques et deux d’entre elles analysent des paramètres cinétiques. Les résultats obtenus par la revue systématique indiquent des modifications variables et non systématiques de la cinématique de course en chaussures minimalistes. En revanche, les paramètres cinétiques sont tous augmentés. Conclusion : Les chaussures minimalistes ne permettent pas de modifier systématiquement la biomécanique de course. Ce travail met en évidence que le type d’attaque au sol importe plus que le type de chaussure. Néanmoins, les chaussures minimalistes sont un moyen de favoriser une attaque avant-pied.

description: Introduction : En ventilation non invasive (VNI), la présence de fuites non-intentionnelles peut être à l’origine de déclenchements intempestifs du ventilateur. Ces asynchronies sont problématiques car elles génèrent de l’inconfort chez le patient, ce qui peut conduire à l’échec du traitement. Deux types de ventilateurs sont utilisés pour la VNI : les ventilateurs de soins intensifs (VSI) et les ventilateurs dédiés à la VNI (VVNI). À l’heure actuelle, la plupart de ces machines disposent d’algorithmes de gestion des fuites permettant de limiter ces auto-déclenchements (AD). Plusieurs études ont comparé l’efficacité de ces algorithmes, mais aucune n’a pu démontrer la prédominance d’un type de ventilateurs à limiter les AD. Objectif : Le but de notre revue est de déterminer si, en présence de fuites non-intentionnelles simulées sur banc d’essai, les VSI limitent les AD aussi efficacement que les VVNI. Méthodologie : La recherche documentaire a été réalisée entre septembre 2013 et janvier 2014 sur les bases de données PubMed, CINAHL, Embase et PEDro. La sélection des études a été effectuée au moyen des critères d’inclusion et d’exclusion établis. Résultats : Après sélection, trois études ont été incluses. Sur un simulateur pulmonaire, les VVNI ont tendance à limiter davantage les AD que les VSI. Cependant, les résultats de ces derniers sont hétérogènes car certains ventilateurs présentent des résultats comparables aux VVNI. Conclusion : Les VVNI ont tendance à mieux se synchroniser lors de la phase de déclenchement. Toutefois, l’hétérogénéité des résultats implique de considérer les modèles plutôt que le type de ventilateurs.

description: This paper considers strongly continuous semigroups of operators on Banach lattices which are locally eventually positive, a property that was first investigated in the context of concrete fourth-order evolution equations. We construct a simple example to show that the typical assumptions on the spectrum of the semigroup generator considered currently in the literature are far from necessary in the more general setting of local eventual positivity. Under minimal additional assumptions, we obtain results on the asymptotic behaviour of orbits, as well as necessary conditions on the peripheral point spectrum of locally eventually positive semigroups.

description: We demonstrate a waveplate for a pseudo-spin-1/2 Bose-Einstein condensate using a two-photon Raman interaction. The angle of the waveplate is set by the relative phase of the optical fields, and the retardance is controlled by the pulse area. The waveplate allows us to image maps of the Stokes parameters of a Bose-Einstein condensate and thereby measure its relative ground state phase. We demonstrate the waveplate by measuring the Stokes parameters of a coreless vortex.

description: The first JWST data on the massive colliding cluster El Gordo confirm 23 known families of multiply lensed images and identify 8 new members of these families. Based on these families, which have been confirmed spectroscopically by MUSE, we derived an initial lens model. This model guided the identification of 37 additional families of multiply lensed galaxies, among which 28 are entirely new systems, and 9 were previously known. The initial lens model determined geometric redshifts for the 37 new systems. The geometric redshifts agree reasonably well with spectroscopic or photometric redshifts when those are available. The geometric redshifts enable two additional models that include all 60 families of multiply lensed galaxies spanning a redshift range $20.8$ and has an estimated virial mass close the maximum mass allowed by standard cosmological models. The JWST images also reveal the presence of small-mass perturbers that produce small lensing distortions. The smallest of these is consistent with being a dwarf galaxy at $z=0.87$ and has an estimated mass of $3.8\times10^9$~\Msol, making it the smallest substructure found at $z>0.5$. The JWST images also show several candidate caustic-crossing events. One of them is detected at high significance at the expected position of the critical curve and is likely a red supergiant star at $z=2.1878$. This would be the first red supergiant found at cosmological distances. The cluster lensing should magnify background objects at $z>6$, making more of them visible than in blank fields of similar size, but there appears to be a deficiency of such objects.

description: Introduction - La fibrose pulmonaire idiopathique (IPF) a des répercussions physiques mais aussi émotionnelles et sociales. La réhabilitation respiratoire (RR) a été démontrée comme efficace chez des patients souffrant de broncho-pneumopathie chronique obstructive. L’IPF ne répondant pas favorablement aux traitements conventionnels, la RR constituerait une alternative thérapeutique intéressante. Objectif - L’objectif de cette revue systématique est de mettre à jour les effets d’un programme de RR sur la capacité physique fonctionnelle et la qualité de vie des patients IPF. Méthodologie – Les recherches ont été effectuées jusqu’au 10 janvier 2014 sur les bases de données CINAHL, The Cochrane Library, Medline (PubMed) et PEDro. Suite au processus de sélection, 7 études de différents designs ont été incluses. La qualité des articles a été évaluée avec une grille de Law et al. (1998) modifiée. Les outils de mesures retenus sont le test de marche de 6 minutes, le Medical Outcome Short Form-36 Health Survey et le Saint George’s Respiratory Questionnaire. Résultats - La majorité des 7 études montre que post-intervention, la RR améliore significativement la capacité physique fonctionnelle, alors que les effets sur la qualité de vie sont plus nuancés. À 6 mois, les bénéfices ne sont pas maintenus. Conclusion - Un programme de RR améliore la capacité physique fonctionnelle post-intervention des patients IPF. Cette efficacité est particulièrement présente chez les sujets dont la sévérité de la pathologie est moindre. À l’avenir, il serait intéressant d’élaborer un programme de RR spécifique aux besoins de la population IPF.

description: Introduction La scoliose idiopathique de l’adolescent (SIA) progresse durant la période de croissance. L’une des déficiences fréquemment observée chez les adolescents atteints de SIA est une perturbation du contrôle postural, qui influence le maintien de l’équilibre. Il n’existe, cependant, aucun consensus concernant ce sujet. L’objectif de ce travail consiste à déterminer quelles sont les variations de maintien de l’équilibre dynamique entre une population atteinte de SIA et une population d’adolescents non scoliotiques. Méthode Nous avons élaboré une revue systématique quantitative. La recherche documentaire a été effectuée sur les bases de données PubMed, PEDro, The Cochrane Library, Trip Database ainsi que Cinahl, de septembre 2013 à janvier 2014. La qualité des articles retenus a été évaluée grâce à la grille McMaster. L’intervention devait permettre d’évaluer les différences d’adaptations d’équilibration entre une population souffrant de SIA et une population d’adolescents non scoliotiques lors de perturbations de l’équilibre dynamique. Concernant les outcomes, il devait s’agir de paramètres évalués par la plateforme de force ou par l’électromyographie de surface (EMG). Résultats Quatre études transversales ont été sélectionnées et leurs résultats ont été synthétisés narrativement. Conclusion Nous avons pu mettre en évidence des variations dans le maintien de l’équilibre dynamique entre ces deux populations. Les principales hypothèses sont la stratégie d’enraidissement du corps, le développement de stratégies adaptatives entrainant une asymétrie entre les membres inférieurs, les changements de tension et de longueur musculaire induits par la déformation vertébrale, ainsi que la distribution anormale des forces sur les articulations des membres inférieurs.

description: Synthetic antiferromagnets with strong perpendicular anisotropy can be modeled by layered Ising antiferromagnets. Accounting for the fact that in the experimental systems the ferromagnetic layers, coupled antiferromagnetically via spacers, are multilayers, we propose a description through Ising films where ferromagnetic stacks composed of multiple layers are coupled antiferromagnetically. We study the equilibrium and non-equilibrium properties of these systems where we vary the number of layers in each stack. Using numerical simulations, we construct equilibrium temperature$-$magnetic field phase diagrams for a variety of cases. We find the same dominant features (three stable phases, where one phase boundary ends in a critical end point, whereas the other phase boundary shows a tricritical point at which the transition changes from first to second order) for all studied cases. Using time-dependent quantities, we also study the ordering processes that take place after a temperature quench. The nature of long-lived metastable states are discussed for thin films, whereas for thick films we compute the surface autocorrelation exponent.

description: The positioning of users using their smartphones represents interesting service for various areas. Position of users can represent valuable information for various service providers. In industry 4.0 smart devices such as smartphone or tablet can help users to react faster in case of emergency. It can help to reduce reaction times for service workers and improve users orientation in the environment, or delegate work to the nearest available employee. In previous work we have described modular positioning system that is able to automatically select optimal positioning module based on available radio signals. In this paper we will focus on estimation of crossing between environments e.g. indoor and outdoor. The proposed algorithm is crucial for implementation of seamless positioning. Since both environments have specific demands not only on positioning solutions but also on maps and navigation algorithms. The proposed algorithm does not require deployment of new infrastructure and can be used on widely available smartphones. The algorithm was tested in real conditions by different users and using various smartphone devices to prove its performance under various conditions.

description: We study gradient corrections to the transport equation for energetic light partons in dense QCD environments. In the diffusion limit, the transport dynamics is solely controlled by small-angle elastic scatterings, leading to transverse momentum broadening with respect to the parton's initial direction. Such a parton propagation is usually considered in the limit of transversely homogeneous matter. The transport processes admit a classical description and the transverse spatial dependence of the medium properties emerges only through the jet quenching parameter. In this work, we show that a gradient expansion of the all-order evolution equation for the partonic Wigner function leads to an evolution equation in the Boltzmann-diffusion form only up to the leading order in transverse gradients. At the second order in gradients, the quantum corrections associated with non-local interactions give rise to a novel transport that can be implemented in Monte Carlo simulations. In addition, using our results, we compute the gradient corrections to the jet quenching parameter in inhomogeneous matter.

description: Occupational safety is a major concern in digital sex work, but workers’ strategies to maintain the right to be safe from physical and psychological harm in the wake of impactful Internet law have yet to be analyzed in peer-reviewed literature. In this study, publications from various digital sex work virtual communities referencing the impact of SESTA-FOSTA will be collected and analyzed through qualitative content analysis to discover how digital sex workers adapt their work safely within legal systems out of their control Sociologists studying both gender and labor have discussed the emotional labor intrinsic to sex work but occupational safety is equally important to the work. By adding the Information Science perspective on the legal landscape of the Internet, this study will consider a more holistic understanding of the work of digital sex work.
