description: We explore the structure and star formation history of the open cluster NGC 2264 (~3 Myr). We combined spectroscopic data from the Gaia-ESO Survey (GES) with multi-wavelength photometry from the Coordinated Synoptic Investigation of NGC 2264 (CSI 2264). We examined a sample of 655 cluster members, including both disk-bearing and disk-free young stars. We find a significant age spread of 4-5 Myr among cluster members. Disk-bearing objects are statistically associated with younger isochronal ages than disk-free sources. The cluster has a hierarchical structure, with two main blocks. The northern half develops around the O-type binary star S Mon; the southern half, close to the tip of the Cone Nebula, contains the most embedded regions of NGC 2264, populated mainly by objects with disks and ongoing accretion. The median ages of objects at different locations within the cluster, and the spatial distribution of disked and non-disked sources, suggest that star formation began in the north of the cluster, over 5 Myr ago, and was ignited in its southern region a few Myr later. Star formation is likely still ongoing in the most embedded regions of the cluster, while the outer regions host a widespread population of more evolved objects. We find a detectable lag between the typical age of disk-bearing objects and that of accreting objects in the inner regions of NGC 2264: the first tend to be older than the second, but younger than disk-free sources at similar locations within the cluster. This supports earlier findings that the characteristic timescales of disk accretion are shorter than those of disk dispersal, and smaller than the average age of NGC 2264 (i.e., < 3 Myr). At the same time, disks in the north of the cluster tend to be shorter-lived (~2.5 Myr) than elsewhere; this may reflect the impact of massive stars within the region (notably S Mon), that trigger rapid disk dispersal.

Short Maturity Forward Start Asian Options in Local Volatility Models

Year: 2017
Subjects: subject: Pricing of Securities (q-fin.PR)

description: We study the short maturity asymptotics for prices of forward start Asian options under the assumption that the underlying asset follows a local volatility model. We obtain asymptotics for the cases of out-of-the-money, in-the-money, and at-the-money, considering both fixed strike and floating Asian options. The exponential decay of the price of an out-of-the-money forward start Asian option is handled using large deviations theory, and is controlled by a rate function which is given by a double-layer optimization problem. In the Black-Scholes model, the calculation of the rate function is simplified further to the solution of a non-linear equation. We obtain closed form for the rate function, as well as its asymptotic behaviors when the strike is extremely large, small, or close to the initial price of the underlying asset.

Tunable critical current for a vortex pinned by a magnetic dipole

Publisher: name: arXiv
Year: 2005
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: \\A simple model for a superconductor with tunable critical current is studied theoretically. The model consists of a thin superconducting film with one vortex interacting with one magnetic dipole, whose magnetic moment is free to rotate, in the presence of a magnetic field applied parallel to the film surfaces. The pinning potential for the vortex is calculated exactly in the London limit. It is found that, due to the dipole freedom to rotate, the dependence of the pinning potential on the applied field is non-trivial, and allows both the spatial dependence and strength of the pinning potential to be changed by the field. As a consequence, the critical current can be tuned by the applied field. The critical current is obtained numerically as a function of the applied field. Order of magnitude changes in the critical current resulting from changes in the direction and magnitude of the applied field are reported, with discontinuous changes taking place in some cases. Possible application to vortices in low-$T_c$ superconducting films pinned by arrays of magnetic dots are briefly considered. \\

description: Real-world safety data for the oral multiple sclerosis (MS) disease-modifying therapies (DMTs), dimethyl fumarate (DMF), fingolimod, and teriflunomide are important. We examined laboratory test abnormalities and adverse health conditions in new users. Linked laboratory and administrative health data were accessed for all persons with MS (PwMS) filling their first oral DMT prescription in two Canadian provinces. PwMS were followed from first prescription fill until discontinuation, death, emigration or study end. Proportions of PwMS, and incidence rates (IR)/100 person-years, were calculated for ≥1 event of elevated alanine aminotransferase (ALT) (>the upper limit of normal [ULN]; all DMTs), liver toxicity (ALT>3xULN; fingolimod); lymphopenia and proteinuria (DMF), and cardiac arrhythmia, hypertension and pneumonia (all DMTs). Overall, 1,140 PwMS were followed for up to 2 years. De novo elevated alanine aminotransferase affected 13.2% (DMF), 12.4% (teriflunomide), and 30.0% (fingolimod) of users. Liver toxicity affected 2.8% of fingolimod, lymphopenia 3.1% of DMF, and proteinuria 2.9% of DMF users. The incidences of cardiac arrhythmia, pneumonia and hypertension ranged from <1 to 1.86/100 person-years depending on the DMT. The short-term, real-world incidences of abnormal laboratory results or adverse events were consistent with the pivotal clinical trial findings. Longer-term safety data are still needed.

description: We present a new processing technique aimed at significantly improving the angular differential imaging method (ADI) in the context of high-contrast imaging of faint objects nearby bright stars in observations obtained with extreme adaptive optics (EXAO) systems. This technique, named "SFADI" for "Speckle-Free ADI", allows to improve the achievable contrast by means of speckles identification and suppression. This is possible in very high cadence data, which freeze the atmospheric evolution. Here we present simulations in which synthetic planets are injected into a real millisecond frame rate sequence, acquired at the LBT telescope at visible wavelength, and show that this technique can deliver low and uniform background, allowing unambiguous detection of $10^{-5}$ contrast planets, from $100$ to $300$ mas separations, under poor and highly variable seeing conditions ($0.8$ to $1.5$ arcsec FWHM) and in only $20$ min of acquisition. A comparison with a standard ADI approach shows that the contrast limit is improved by a factor of $5$. We extensively discuss the SFADI dependence on the various parameters like speckle identification threshold, frame integration time, and number of frames, as well as its ability to provide high-contrast imaging for extended sources, and also to work with fast acquisitions.

description: Introduction. Le questionnaire parental Developmental Coordination Disorder Questionnaire’07 (DCDQ’07) est un instrument de mesure fiable et valide pour dépister le trouble de l’acquisition de la coordination (TAC) chez les enfants. La version pour la population francophone d’Europe du DCDQ’07, le Questionnaire du Trouble de l'Acquisition de la Coordination (QTAC-FE), produite suivant une procédure reconnue d’adaptation transculturelle, comporte des différences linguistiques et culturelles avec la version originale, raison pour laquelle il est importe d’étudier ses qualités métrologiques.But. Cette étude visait à évaluer la fidélité inter-langue, la cohérence interne et la validité de constuit du QTAC-FE.Méthode. Des parents d’enfants (âge moyen (écart-type) = 8,8 (2,8)) avec suivi en ergothérapie en raison de faibles habiletés de coordination motrice (n=8) et sans suivi et sans difficultés motrices connues (n=22) ont rempli le QTAC-FE et le DCDQ’07 dans un ordre aléatoire, avec un intervalle moyen de près de 40 jours.Résultats. La concordance des résultats pour les trois facteurs et le résultat total entre les deux versions est élevée (coefficients de corrélation intraclasse = 0,88 – 0,91). Toutefois, la moyenne des résultats obtenus avec le QTAC-FE est significativement supérieure à celle obtenue avec le DCDQ’07. Le QTAC-FE distingue les deux groupes d'enfants avec et sans suivi en ergothérapie et la cohérence interne de ses items est excellente (alpha de Cronbach = 0,94).Conclusion. Le QTAC-FE est une traduction fiable du DCDQ’07 pour un usage auprès d’une population francophone d’Europe.

description: We construct a family of warped AdS_5 compactifications of IIB supergravity that are the holographic duals of the complete set of N=1 fixed points of a Z_2 quiver gauge theory. This family interpolates between the T^{1,1} compactification with no three-form flux and the Z_2 orbifold of the Pilch-Warner geometry which contains three-form flux. This family of solutions is constructed by making the most general Ansatz allowed by the symmetries of the field theory. We use Killing spinor methods because the symmetries impose two simple projection conditions on the Killing spinors, and these greatly reduce the problem. We see that generic interpolating solution has a nontrivial dilaton in the internal five-manifold. We calculate the central charge of the gauge theories from the supergravity backgrounds and find that it is 27/32 of the parent N=2, quiver gauge theory. We believe that the projection conditions that we derived here will be useful for a much larger class of N=1 holographic RG-flows.

description: The production of antiprotons in $pp$ collisions is investigated close to threshold where experimental data about the total cross section are not available. We analyze the latter reaction within the LUND string model for inclusive $\bar{p}$ production and within the framework of a one-boson exchange model for the exclusive reaction $pp \rightarrow ppp\bar{p}$. The application of our new results to the analysis of subthreshold antiproton production in $d + p$ and $d + d$ collisions shows cross sections that are much lower than expected before. Nevertheless, the comparison of experimental $\bar{p}$ differential cross sections from $d +p$ and $d + d$ is expected to provide valuable information about a nonnucleonic component in the deuteron wavefunction.

description: After reviewing the most important COMPASS results on transverse spin effects in SIDIS, I will present the recent work we have done on weighted Sivers asymmetries and "transversity induced" $Λ$ polarisation. Using the high statistics data collected in 2010 on a transversely polarised proton target COMPASS has evaluated the transverse momentum weighted Sivers asymmetries both in $x$- and in $z$-bins. The results are also compared with the standard unweighted asymmetries. Using the whole data sample collected over the years on transversely polarised deuteron and proton targets COMPASS has measured the transversity induced $Λ$ polarisation in the reaction $μN \rightarrow μ' ΛX$. Possible future SIDIS COMPASS measurements will also be briefly mentioned.

description: In July of 1906, Blanco y negro published a brief story by Blanca de los Ríos entitled “Metempsicosis: De las ‘memorias’ del doctor Hipnos,” which dramatizes the ominous dangers of hypnotism.1 In the story, a medical student, driven by his obsession for Susana, pays a traveling hypnotizer to “infundir mi alma en [el] cuerpo [de Alberto de San Andrés],” Susana’s husband (“Metempsicosis” 51). His subsequent confession to Susana about his actions precipitates her death, which in turn causes the student to go insane. In the final lines of the story, Hipnos reflects on the tragic outcome and the perils of hypnotism: “¿Infundieron en Alberto otra alma, ó […] le sugestionaron con la idea de habérsela infundido? ¡Qué importa! ¡Mataron en él el albedrío, la fe en el propio yo […] ¿Será esa fe la chispa animadora, el quid divinum, la esencia de Dios que prende en la célula psíquica […]?” (author’s emphasis). For Hipnos, the consequences of either metempsychosis or hypnotic suggestion for Alberto are more significant than the issue of which of the two pseudo-sciences actually led to his demise. Whatever the medical student’s method, he had robbed Alberto of both his will (“albedrío”) and his sense of self (“la fe en el propio yo”). In short he destroyed Alberto’s subjectivity, Alberto’s body being but the physical shell of an identity that no longer existed.

La quasi-totalité des personnes atteintes d’un syndrome du canal carpien rapportent des problèmes à effectuer leurs occupations et près de la moitié n'auront d’autre recours que la chirurgie parce qu’elles ne connaissent pas les autres traitements disponibles. La pratique auprès de cette clientèle interpelle donc particulièrement les ergothérapeutes dans leur rôle d’agent de changement dans une perspective d’habilitation de l’occupation centrée sur le client.Objectif. Le présent article présente une étude de validation auprès d’experts d’un suivi nommé « Pour avoir tous les atouts en main ». Celui-ci s’appuie sur l’approche participative du « patient partenaire de soins », l’habilitation aux occupations centrée sur le client et la pratique fondée sur les résultats probants.Méthode. L’étude de validation de contenu et de faisabilité d’un suivi a été faite à partir d’un questionnaire incluant une échelle de type Likert et des commentaires qualitatifs. Ainsi, dix cliniciens ont été recrutés à titre d’experts pour évaluer le suivi proposé. Résultats. Les résultats obtenus indiquent que l’évaluation de la validité de contenu et de la faisabilité du suivi proposé sont non seulement soutenus par des moyennes élevées, mais aussi par des commentaires favorables. Également, les commentaires recueillis font ressortir que les experts consultés acceptent le suivi proposé et le considèrent comme étant cliniquement intéressant. Conclusion. Les ergothérapeutes ont maintenant à leur disposition un suivi novateur, favorablement accueilli par les cliniciens consultés.
title: Mapping the Gothic Urban Imaginary in Juan Martínez Villergas’s Los misterios de Madrid
Creators: name: Delano, Cristina
Publisher: name: Utah State University
Year: 2015

description: The nineteenth-century mystery novel was among the first narrative genres to capture the modern urban experience. The foundational text of this genre, Eugène Sue’s Les Mystères de Paris (1841-1843), portrayed Paris’s criminal underworld to the titillation of middle class readers.1 Sue wrote his novel at a moment of intense urban growth and change, and his novel served to “shape the popular imagination as to what the city was and might become” (Harvey 25). Sue’s novel sparked a “manía misterial” (Milá de la Roca iii) throughout Europe and the Americas.2 In Spain alone there were misterios about Madrid, Barcelona, Cádiz, Córdoba, and Seville. In Madrid, the city mystery trend coincided with a crucial moment in the development of the urban imaginary of the capital city. Madrid was suffering from an image problem. By the 1830s, Spain had lost the majority of its colonies in the Americas, and Madrid appeared to be politically and culturally stagnated (Juliá 322). The city’s appearance and infrastructure did little to evoke the capital of an empire. As Richard Ford described in his 1844 Handbook for Travellers to Spain, Madrid was “disagreeable and unhealthy” (III: 1075). The fledgling liberal government tried to solve Madrid’s physical deficiencies while also creating a capital that would be a symbol of the modern nation. Before the construction of a “new” Madrid in the 1860s, the first half of the century saw urban reform movements (most notably the desamortización de Mendizábal in 1836) that forced a negotiation of historical memory and the new social and political order.3 These reforms not only changed the urban topography but also rewrote the narrative of the city.
Quantum lattice solitons in ultracold bosons near Feshbach resonance

description: Quantum lattice solitons in a system of two ultracold bosons near Feshbach resonance are investigated. It is shown that their binding energy, effective mass, and spatial width, can be manipulated varying the detuning from the Feshbach resonance. In the case of attractive atomic interactions, the molecule creation stabilizes the solitons. In the case of repulsive interactions, the molecule creation leads to the possibility of existence of bright solitons in some interval of detunings. Due to quantum fluctuations the soliton width is a random quantity. Its standard deviation is larger than the mean value for such a small number of particles.

description: Inspired by the interpretation of two dimensional Yang-Mills theory on a cylinder as a random walk on the gauge group, we point out the existence of a large N transition which is the gauge theory analogue of the cutoff transition in random walks. The transition occurs in the strong coupling region, with the 't Hooft coupling scaling as alpha*log(N), at a critical value of alpha (alpha = 4 on the sphere). The two phases below and above the transition are studied in detail. The effective number of degrees of freedom and the free energy are found to be proportional to N^(2-alpha/2) below the transition and to vanish altogether above it. The expectation value of a Wilson loop is calculated to the leading order and found to coincide in both phases with the strong coupling value.

description: Creating high-quality vector vortex (VV) beams is possible with a myriad of techniques at low power, and while a few studies have produced such beams at high-power, none have considered the impact of amplification on the vector purity. Here we employ novel tools to study the amplification of VV beams, and in particular the purity of such modes. We outline a general toolbox for such investigations and demonstrate its use in the general case of VV beams through a birefringent gain medium. Intriguingly, we show that it is possible to enhance the purity of such beams during amplification, paving the way for high-brightness VV beams, a requirement for their use in high-power applications such as laser materials processing.

description: In April 2006 at the annual Kentucky Foreign Language Conference (KFLC), Decimonónica sponsored a session honoring Donald Leslie Shaw’s broad scholarly contributions to Hispanism. It was one of five different panels organized for this renowned scholar in addition to a grand luncheon that celebrated his remarkable career and presented him Modernisms and Modernities: Studies in Honor of Donald L. Shaw, a Festschrift edited by Susan Carvalho that included her 12-page introduction, a wonderful biographical sketch of Shaw. Those of us present for these various tributes in Kentucky will never forget how visibly overwhelmed Shaw was by the multiple public gestures, to include his induction into the prestigious Orden de Don Quijote, one of the highest international honors of Sigma Delta Pi, the National Collegiate Hispanic Honor Society. And although these various recognitions reconfirmed the huge impact Shaw had made on both Latin American and Spanish literary studies, the fact that the venue was his beloved Kentucky Foreign Language Conference, an annual “pilgrimage” he refused to miss because of its reunion with dear students, colleagues and friends, made the collective homage even more meaningful.

Applying ACO To Large Scale TSP Instances

Year: 2017
Subjects: subject: Neural and Evolutionary Computing (cs.NE)
subject: FOS: Computer and information sciences

description: Ant Colony Optimisation (ACO) is a well known metaheuristic that has proven successful at solving Travelling Salesman Problems (TSP). However, ACO suffers from two issues; the first is that the technique has significant memory requirements for storing pheromone levels on edges between cities and second, the iterative probabilistic nature of choosing which city to visit next at every step is computationally expensive. This restricts ACO from solving larger TSP instances. This paper will present a methodology for deploying ACO on larger TSP instances by removing the high memory requirements, exploiting parallel CPU hardware and introducing a significant efficiency saving measure. The approach results in greater accuracy and speed. This enables the proposed ACO approach to tackle TSP instances of up to 200K cities within reasonable timescales using a single CPU. Speedups of as much as 1200 fold are achieved by the technique.

Finite size scaling procedures are performed. Results and analyses based on $Φ$ confirm a zero temperature phase transition and allow to identify the low temperature phase. The advantages of $Φ$ are brought out and its physical meaning is established.

description: We report the discovery of an active nucleus in a poststarburst galaxy, KUG1259+280. High resolution X-ray imaging observations with ROSAT HRI show that X-ray emission from KUG1259+280 is unresolved. X-ray emission from KUG1259+280 is highly variable, an episode in which X-ray intensity changed by a factor 2.5 within about 1300s has been detected. ROSAT PSPC spectra of this galaxy is found to be well represented by a steep power law of photon index 4.25, and a change in the absorbing column within about a day is indicated. The rest frame intrinsic X-ray luminosity of KUG1259+280 is found to be 3.6-4.7X10^42 erg/s similar to that of low luminosity Seyfert galaxies. Mass of the central massive object within KUG1259+280 is estimated to be in the range of 10^5-10^7 M_sun. Optical spectrum of the nuclear region of the galaxy is complex and shows Balmer absorption and collisionally excited lines of [OIII], and [NII]. The presence of forbidden emission lines and the absence of Balmer emission lines in spectrum of KUG1259+280 could be due to photoionization by a diluted power-law continuum modified by enhanced stellar absorption due to a poststarburst event. Estimated Balmer line strengths free of stellar absorptions and forbidden line strengths indicate the nucleus of KUG1259+280 to be LINER-like in nature. However, the low-ionization forbidden line [OI]6300 usually present in LINER spectra, is not detected in the spectrum of KUG1259+280. X-ray characteristics -- variability, point-like appearance, luminosity and steepness of spectrum indicate that nucleus in KUG1259+280 is active and perhaps like that of narrow-line Seyfert type 1 galaxies.

The evolution of the temperature field during cavity collapse in liquid nitromethane. Part II: Reactive case

description: We study effect of cavity collapse in non-ideal explosives as a means of controlling their sensitivity. The main aim is to understand the origin of localised temperature peaks (hot spots) that play a leading order role at early ignition stages. Thus, we perform 2D and 3D numerical simulations of shock induced single gas-cavity collapse in nitromethane. Ignition is the result of a complex interplay between fluid dynamics and exothermic chemical reaction. In part I of this work we focused on the hydrodynamic effects in the collapse process by switching off the reaction terms in the mathematical model. Here, we reinstate the reactive terms and study the collapse of the cavity in the presence of chemical reactions. We use a multi-phase formulation which overcomes current challenges of cavity collapse modelling in reactive media to obtain oscillation-free temperature fields across material interfaces to allow the use of a temperature-based reaction rate law. The mathematical and physical models are validated against experimental and analytic data. We identify which of the previously-determined (in part I of this work) high-temperature regions lead to ignition and comment on their reactive strength and reaction growth rate. We quantify the sensitisation of nitromethane by the collapse of the cavity by comparing ignition times of neat and single-cavity material; the ignition occurs in less than half the ignition time of the neat material. We compare 2D and 3D simulations to examine the change in topology, temperature and reactive strength of the hot spots by the third dimension. It is apparent that belated ignition times can be avoided by the use of 3D simulations. The effect of the chemical reactions on the topology and strength of the hot spots in the timescales considered is studied by comparing inert and reactive simulations and examine maximum temperature fields and their growth rates.

description: Introduction. Vivre avec une problématique de santé mentale et un trouble lié à l’utilisation de substances (TLUS) amènent plusieurs difficultés fonctionnelles affectant la vie sociale, la vie productive, les conditions de vie ainsi que la qualité de vie. Les ergothérapeutes interviennent actuellement auprès de cette clientèle présentant de la comorbidité dans les programmes de soins intégrés ou en santé mentale. Malgré tout, il existe peu d’écrits permettant d’identifier leur rôle auprès de cette clientèle.Méthodologie. L’objectif principal est de documenter les pratiques actuelles des ergothérapeutes au Québec auprès d’une clientèle atteinte d’un trouble comorbide de santé mentale et TLUS. Un devis de recherche descriptive interprétative a été choisi. Deux groupes de discussion focalisés ont été tenus avec des ergothérapeutes de différents milieux. Les discussions avaient pour but de documenter les outils, les approches et les modèles utilisés par les participants dans leur processus d’évaluation et d’intervention, mais également leurs recommandations afin d’améliorer leur pratique auprès d’une clientèle atteinte de comorbidité.Résultats. Onze ergothérapeutes de quatre milieux cliniques différents ont participé à ce projet. Les ergothérapeutes consultés apprécient les modèles et outils spécifiques à leur profession, combinés à une approche de réduction des méfaits. De plus, leurs propos offrent une compréhension occupationnelle des TLUS en considérant la consommation comme une activité significative.Conclusion. Cette nouvelle vision permet aux ergothérapeutes qui travaillent auprès d’une clientèle présentant de la comorbidité d’intervenir de façon simultanée sur les deux problématiques mais surtout d’offrir leur expertise dans l’analyse d’activité et du fonctionnement humain.
Perspectives on characteristics based curse-of-dimensionality-free numerical approaches for solving Hamilton-Jacobi equations
Creators: name: Yegorov, Ivan

description: This paper extends the considerations of the works [1, 2] regarding curse-of-dimensionality-free numerical approaches to solve certain types of Hamilton-Jacobi equations arising in optimal control problems, differential games and elsewhere. A rigorous formulation and justification for the extended Hopf-Lax formula of [2] is provided together with novel theoretical and practical discussions including useful recommendations. By using the method of characteristics, the solutions of some problem classes under convexity/concavity conditions on Hamiltonians (in particular, the solutions of Hamilton-Jacobi-Bellman equations in optimal control problems) are evaluated separately at different initial positions. This allows for the avoidance of the curse of dimensionality, as well as for choosing arbitrary computational regions. The corresponding feedback control strategies are obtained at selected positions without approximating the partial derivatives of the solutions. The results of numerical simulations demonstrate the high potential of the proposed techniques. It is also pointed out that, despite the indicated advantages, the related approaches still have a limited range of applicability, and their extensions to Hamilton-Jacobi-Isaacs equations in zero-sum two-player differential games are currently developed only for sufficiently narrow classes of control systems. That is why further extensions are worth investigating.

Baryon Density and the Dilated Chiral Quark Model

description: We calculate perturbatively the effect of density on hadronic properties using the chiral quark model implemented by the QCD trace anomaly to see the possibility of constructing Lorentz invariant Lagrangian at finite density. We calculate the density dependent masses of the constituent quark, the scalar field and the pion in one-loop order using the technique of thermo field dynamics. In the chiral limit, the pion remains massless at finite density. It is found that the tadpole type corrections lead to the decreasing masses with increasing baryon density, while the radiative corrections induce Lorentz-symmetry-breaking terms. We found in the large $N_c$ limit with large scalar mass that the tadpoles dominate and the mean-field approximation is reliable, giving rise a Lorentz-invariant Lagrangian with masses decreasing as the baryon density increases.

description: Integrated Model of Distributed Systems is used for specification and verification of distributed systems. In the formalism, a system is modeled as a set of servers' states and agents' messages. The operation of a system is modeled as actions converting global system configuration (a set of states and messages) to a new configuration. The formalism is used in Dedan verification environment, in which specification and verification of distributed systems is performed. Equivalent Petri nets are used for structural analysis. For the graphical specification and simulation of distributed systems, Distributed Autonomous and Asynchronous Automata (DA3) are invented. Such simulation does not require calculation of global configuration space of a system. Two forms of DA3 are shown: Server-DA3 (SDA3) for the server view and Agent-DA3 (ADA3) for the agent view.

description: Introduction. Les personnes ayant un trouble du spectre de l’autisme (TSA) éprouvent de nombreuses difficultés sur le plan occupationnel. Plusieurs études démontrent que les technologies informatiques peuvent apporter des solutions pour ces personnes et les technologies mobiles (TM) de type assistant numérique personnel, tablette et télé­phone intelligent offrent des opportunités sans précédent.Objectif. Cette étude explore l’intérêt de l’utilisation des TM pour améliorer le ren­de­ment occupationnel de personnes ayant un TSA.Méthode. Le devis choisi est une étude exploratoire, descriptive et mixte. Les données pro­vi­ennent de la Mesure canadienne du rendement occupationnel, d’entretiens et d’ob­ser­vations.Résultats. Vingt-six personnes ont pris part à l’étude, ont expérimenté des applications pour TM en fonction de leurs objectifs occupationnels et ont obtenu des gains sur le plan du rendement occupationnel et de la satisfaction face à ce rendement. Les données qualitatives montrent l’apport spécifique des TM pour les participants. Les gains les plus importants concernent les personnes ayant des troubles moteurs ou dyspraxiques pour lesquelles la tablette offre un accès facilité et de nombreuses possibilités sur le plan occupationnel. L’étude a permis d’identifier plusieurs applications performantes pour l’atteinte des objectifs des participants.Discussion. Plusieurs caractéristiques des TM sont avantageuses et globalement, elles respectent davantage les principes d’accessibilité universelle définis pour les outils que les ordinateurs. Elles permettent également de cibler les quatre sources de dé­ve­lop­pement du sentiment d’efficacité personnelle, particulièrement la possibilité de faire vivre des succès grâce au grand nombre d’applications disponibles et aux nombreuses pos­sibilités d’ajustements.Conclusion. Convenablement utilisées, les TM peuvent apporter des bénéfices aux per­sonnes ayant un TSA. Les ergothérapeutes peuvent contribuer au développement de solutions recourant à l’utilisation de TM ou d’autres technologies novatrices pour les personnes ayant des difficultés occupationnelles.

description: We study the relation between sweeping processes with the cone of limiting normals and projection processes. We prove the existence of solution of a perturbed sweeping process with the cone of limiting normals and of nonstationary projection process, provided the sets involved are definable (and are moving in a definable way) in some o-minimal structure. An application to a crowd motion model is presented.

description: We study an ad hoc extension of the Lattice-Boltzmann method that allows the simulation of non-Newtonian fluids described by generalized Newtonian models. We extensively test the accuracy of the method for the case of shear-thinning and shear-thickening truncated power-law fluids in the parallel plate geometry, and show that the relative error compared to analytical solutions decays approximately linear with the lattice resolution. Finally, we also tested the method in the reentrant-flow geometry, in which the shear-rate is no-longer a scalar and the presence of two singular points requires high accuracy in order to obtain satisfactory resolution in the local stress near these points. In this geometry, we also found excellent agreement with the solutions obtained by standard finite-element methods, and the agreement improves with higher lattice resolution.
