description: At present, there are two possible, and equally plausible, explanations for the physics of quantum measurement. The first explanation, known as the many-worlds interpretation, does not require any modification of quantum mechanics, and asserts that at the time of measurement the Universe splits into many branches, one branch for every possible alternative. The various branches do not interfere with each other because of decoherence, thus providing a picture broadly consistent with the observed Universe. The second explanation, which requires quantum mechanics to be modified from its presently known form, is that at the time of measurement the wave-function collapses into one of the possible alternatives. The two explanations are mutually exclusive, and up until now, no theoretical reasoning has been put forward to choose one explanation over the other. In this article, we provide an argument which implies that the collapse interpretation is favored over the many-worlds interpretation. Our starting point is the assertion (which we justify) that there ought to exist a reformulation of quantum mechanics which does not refer to a classical spacetime manifold. The need for such a reformulation implies that quantum theory becomes non-linear on the Planck mass/energy scale. Standard linear quantum mechanics is an approximation to this non-linear theory, valid at energy scales much smaller than the Planck scale. Using ideas based on noncommutative differential geometry, we develop such a reformulation and derive a non-linear Schrödinger equation, which can explain collapse of the wave-function. We also obtain an expression for the lifetime of a quantum superposition. We suggest ideas for an experimental test of this model.

description: This paper investigates the use and extension of text retrieval and clustering techniques for event detection. The task is to automatically detect novel events from a temporally-ordered stream of news stories, either retrospectively or as the stories arrive. We applied hierarchical and non-hierarchical document clustering algorithms to a corpus of 15,836 stories, focusing on the exploitation of both content and temporal information. We found the resulting cluster hierarchies highly informative for retrospective detection of previously unidentified events, effectively supporting both query-free and query-driven retrieval. We also found that temporal distribution patterns of document clusters provide useful information for improvement in both retrospective detection and on-line detection of novel events. In an evaluation using manually labelled events to judge the system-detected events, we obtained a result of 82% in the Fl measure for retrospective detection, and a Fl value of 42% for on-line detection.

description: We formally deduce closed-form expressions for the transmitted effective wavenumber of a material comprising multiple types of inclusions or particles (multi-species), dispersed in a uniform background medium. The expressions, derived here for the first time, are valid for moderate volume fractions and without restriction on the frequency. We show that the multi-species effective wavenumber is not a straightforward extension of expressions for a single species. Comparisons are drawn with state-of-the-art models in acoustics by presenting numerical results for a concrete and a water-oil emulsion in two dimensions. The limit of when one species is much smaller than the other is also discussed and we determine the background medium felt by the larger species in this limit. Surprisingly, we show that the answer is not the intuitive result predicted by self-consistent multiple scattering theories. The derivation presented here applies to the scalar wave equation with cylindrical or spherical inclusions, with any distribution of sizes, densities, and wave speeds. The reflection coefficient associated with a half-space of multi-species cylindrical inclusions is also formally derived.

Comment une meilleure compréhension des rôles des femmes au sein des groupes terroristes aiderait-elle à concevoir des stratégies antiterroristes plus efficaces?

description: Depuis plusieurs années, la lutte contre le terrorisme et la radicalisation menant à la violence est une priorité pour plusieurs pays, dont le Canada. En effet, nous constatons que les États ne lésinent pas sur leurs efforts dans le but de mettre en place des stratégies pour contrer la menace terroriste sur le plan national et international. Néanmoins, nous voyons que pour y parvenir, l’attention a été particulièrement mise sur la participation des hommes dans les groupes terroristes tout en minimisant à la même occasion la place et les actions des femmes au sein de ces derniers. C’est pourquoi ce mémoire se veut une réflexion sur l’implication active des femmes dans le terrorisme, plus spécifiquement sur leurs rôles au sein des organisations terroristes dans la perspective de proposer des recommandations applicables dans les stratégies antiterroristes actuellement en place au Canada et ailleurs dans le monde. Contrairement aux idées répandues dans les médias et dans la littérature scientifique que les femmes impliquées dans les groupes radicaux ne sont que des victimes d’un entourage les forçant à la radicalisation, dans ce mémoire nous analyserons une position opposée à ce postulat. En effet, de la femme kamikaze à la femme recruteuse et formatrice en passant par la mariée djihadiste, la présence féminine au sein des mouvements terroristes s’est accentuée au fil des années et l’impact de leurs actions s’est observé dans l’avancement du terrorisme. C’est pourquoi, dans le cadre de cette recherche, nous proposons d’analyser les motivations profondes qui poussent les femmes à la radicalisation et au choix du chemin du terrorisme pour une meilleure compréhension de leurs rôles dans des groupes terroristes. De plus, nous présentons quelques-unes des raisons pour lesquelles les organisations terroristes encouragent la présence et la participation active des femmes radicalisées dans leurs rangs. Enfin, nous proposons des pistes de réflexion sur la manière dont la participation et les rôles des femmes peuvent être réévalués dans l’élaboration des politiques de lutte contre le terrorisme, et ce, afin de les rendre plus efficaces

description: We construct several examples of genus-one fibered K3 surfaces without a global section with type $I_{n}$ fibers, by considering double covers of a special class of rational elliptic surfaces lacking a global section, known as Halphen surfaces of index 2. The resulting K3 surfaces have bisection geometries. F-theory compactifications on these K3 genus-one fibrations without a section times a K3 yield models that have $SU(n)$ gauge symmetries with a discrete $\mathbb{Z}_2$ symmetry.

description: It has been pointed out that a large non-minimal coupling $ξ$ between the Higgs and the Ricci scalar can source higher derivative operators, which may change the predictions of Higgs inflation. A variant, called critical Higgs inflation, employs the near-criticality of the top mass to introduce an inflection point in the potential and lower drastically the value of $ξ$. We here study whether critical Higgs inflation can occur even if the pre-inflationary initial conditions do not satisfy the slow-roll behaviour (retaining translation and rotation symmetries). A positive answer is found: inflation turns out to be an attractor and therefore no fine-tuning of the initial conditions is necessary. A very large initial Higgs time-derivative (as compared to the potential energy density) is compensated by a moderate increase in the initial field value. These conclusions are reached by solving the exact Higgs equation without using the slow-roll approximation. This also allows us to treat consistently the inflection point, where the standard slow-roll approximation breaks down. Here we make use of an approach that is independent of the UV completion of gravity, by taking initial conditions that always involve sub-planckian energies.

description: Most synthesis techniques provide for some amount of parametric control. Generating suitable controls is a difficult problem, especially for instruments that admit continuous control by the performer. The traditional approach to control generation in computer music has been note-based, but note-by-note synthesis tends to overlook the interaction between notes in a phrase. This study considers factors, including melodic contour, articulation, and dynamics, that affect the shape of amplitude envelopes in trumpet performance. After showing statistically significant variation due to these factors, a model for trumpet envelopes is described. This model is used with Spectral Interpolation Synthesis to synthesize realistic trumpet performances.

description: Projectors are a simple but powerful tool for manipulating and probing quantum systems. For instance, projecting two-qubit systems onto maximally entangled states can enable quantum teleportation. While such projectors have been extensively studied, partially-entangling projectors have been largely overlooked, especially experimentally, despite their important role in quantum foundations and quantum information. Here, we propose a way to project two polarized photons onto any state with a single experimental setup. Our scheme does not require optical nonlinearities or additional photons. Instead, the entangling operation is provided by Hong–Ou–Mandel interference and post-selection. The efficiency of the scheme is between 50% and 100%, depending on the projector. We perform an experimental demonstration and reconstruct the operator describing our measurement using detector tomography. Finally, we flip the usual role of measurement and state in Hardy's test by performing a partially-entangling projector on separable states. The results verify the entangling nature of our measurement with six standard deviations of confidence.

description: Ce mémoire est une recherche qualitative qui s’intéresse aux facteurs favorables et défavorables à l’atteinte des objectifs des équipes mixtes (EM). Les équipes mixtes au Canada sont habituellement constituées d’un policier et d’un intervenant psychosocial qui interviennent auprès de personne en situation de crise (Shapiro et collab., 2015). Cette recherche s’est spécifiquement intéressée à l’Équipe mobile d’intervention psychosociale (EMIP) à Sherbrooke et le Mobile Crisis Team (MCIT) à Toronto. La méthodologie utilisée est l’analyse de contenu et le cadre théorique est l’analyse stratégique de Michel Crozier et Ehrard Friedberg (1977) qui a permis de mieux comprendre les dynamiques et relations de pouvoir entre les acteurs des EM. Les résultats : les facteurs favorables à l’atteinte des objectifs de l’EM sont en lien avec les compétences interpersonnelles des membres de l’équipe, de la structure de l’organisation, des formations de santé mentale, l’uniforme, la collaboration, les ressources disponibles et les facteurs légaux encadrent l’EM. Les facteurs défavorables sont le manque de financement, les lacunes des formations, les barrières légales, la culture policière et les limites de collaboration.
Familles immigrantes récentes : comprendre les stratégies de résilience pour offrir les meilleurs services

Year: 2022

description: Le Canada est un pays qui valorise la diversité. En 2016, on estimait que 3,5 % de la population totale du Canada était composée par des immigrants récents (Statistiques Canada, 2017). L’objet 3.1.e de la loi sur l’immigration est la protection des réfugiés de 2001 est « de promouvoir l’intégration des résidents permanents au Canada, compte tenu du fait que cette intégration suppose des obligations pour les nouveaux arrivants et pour la société canadienne » (Gouvernement du Canada, 2022). Malgré ça, les immigrants récents ont des faibles revenus (Citoyenneté et immigration Canada, 2013) et leur taux de chômage est élevé (Arcand, Lenoir-Achdjian et Helly, 2009). Également, « l’insertion culturelle en pays d’accueil peut entrainer des modifications profondes au niveau identitaire » (Cardu et Bouchamma, 2000, p.2). En nous basant sur ces constants, nous avons voulu savoir si les stratégies de résilience que les familles immigrantes récentes mettent en œuvre pour surmonter leurs défis interfèrent et participent à leur insertion professionnelle et à leur intégration culturelle. Nous avons eu recours à la théorie de résilience et l’approche structurelle pour étudier les stratégies de résilience dans leur parcours migratoire et pour trouver des recommandations pour les organismes communautaires et pour les décideurs politiques en vue d’améliorer leurs services. La méthodologie qualitative a été utilisée. Quatre entrevues semi-dirigées d’une durée approximative de 60 minutes ont été menées. Nous avons comparé nos résultats aux résultats d’autres chercheurs. Le recours aux réseaux et aux organismes communautaires, l’usage des habiletés acquises à l’école, le maintien de certaines valeurs de la culture d’origine, la socialisation et la mobilité sont certaines des stratégies de résilience qui aident les immigrants récents dans leur insertion professionnelle et dans leur intégration culturelle. Mots clés : immigrant récent, insertion professionnelle, intégration culturelle, enjeux, stratégies, théorie de résilience, approche structurelle.
The Critical Properties of Two-dimensional Oscillator Arrays

description: We present a renormalization group study of two dimensional arrays of oscillators, with dissipative, short range interactions. We consider the case of non-identical oscillators, with distributed intrinsic frequencies within the array and study the steady-state properties of the system. In two dimensions no macroscopic mutual entrainment is found but, for identical oscillators, critical behavior of the Berezinskii-Kosterlitz-Thouless type is shown to be present. We then discuss the stability of (BKT) order in the physical case of distributed quenched random frequencies. In order to do that, we show how the steady-state dynamical properties of the two dimensional array of non-identical oscillators are related to the equilibrium properties of the XY model with quenched randomness, that has been already studied in the past. We propose a novel set of recursion relations to study this system within the Migdal Kadanoff renormalization group scheme, by mean of the discrete clock-state formulation. We compute the phase diagram in the presence of random dissipative coupling, at finite values of the clock state parameter. Possible experimental applications in two dimensional arrays of microelectromechanical oscillators are briefly suggested.

description: Chronic wounds affect ~2% of the U.S. population and increase risks of amputation and mortality. Unfortunately, treatments for such wounds are often expensive, complex, and only moderately effective. Electrotherapy represents a cost-effective treatment; however, its reliance on bulky equipment limits its clinical use. Here, we introduce water-powered, electronics-free dressings (WPEDs) that offer a unique solution to this issue. The WPED performs even under harsh conditions-situations wherein many present treatments fail. It uses a flexible, biocompatible magnesium-silver/silver chloride battery and a pair of stimulation electrodes; upon the addition of water, the battery creates a radial electric field. Experiments in diabetic mice confirm the WPED's ability to accelerate wound closure and promote healing by increasing epidermal thickness, modulating inflammation, and promoting angiogenesis. Across preclinical wound models, the WPED-treated group heals faster than the control with wound closure rates comparable to treatments requiring expensive biologics and/or complex electronics. The results demonstrate the WPED's potential as an effective and more practical wound treatment dressing.
Analyse intersectionnelle de la littérature sur l’itinérance des femmes au Québec : Pour un accompagnement plus inclusif
Creators: name: Guillaume, Iseraline
Publisher: name: My University
Year: 2023

description: L’itinérance chez les femmes est longtemps restée dans l’ombre, car très peu de recherches empiriques l’ont examinée (La Rue des femmes de Montréal, 2010 ; Bourque, Grenier et collab., 2019 ; Flynn, Turcotte et collab., 2020). Par conséquent, elle reçoit très peu d’attention des politiques sociales visant à la combattre. Or, les obstacles systémiques auxquels font face les femmes diffèrent de ceux des hommes en situation d’itinérance (Gélineau, Dupéré et collab., 2015). Cela dit, lorsque ce problème est abordé, un survol de la littérature sur ce sujet révèle que, très souvent, une lecture homogène en est faite. Cela traduit un certain mépris pour les spécificités des différentes catégories de femmes en situation d’itinérance, ce qui contribue grandement à renforcer leur invisibilité au sein de la société. Ce mémoire présente un bilan critique des connaissances sur les réalités des femmes canadiennes et, plus particulièrement, des québécoises vivant dans un contexte d’itinérance. À partir d’une analyse thématique de la littérature et en recourant à l’approche féministe intersectionnelle, le mémoire présente d’abord les facteurs structurels qui peuvent mener cette population à la rue. Il enchaîne ensuite avec les différentes réalités et défis auxquels ces femmes font face quotidiennement dans leur trajectoire de rue. Enfin, les différentes ressources disponibles pour aider cette population sont discutées. En conclusion, au lieu de présenter de nouvelles recommandations, le mémoire prend appui sur les recommandations existantes afin d’encourager les acteurs politiques et les intervenant-es communautaires à revoir leurs pratiques selon les principes de l’intervention féministe intersectionnelle, ainsi qu’à prendre en compte la pratique réflexive dans leur façon d’appréhender le problème, en vue de mieux accompagner les femmes itinérantes.

description: We study how migration affects stars of a galaxy with a thin stellar disc and thicker stellar components. The simulated galaxy has a strong bar and lasting spiral arms. We find that the amplitude of the churning (change in angular momentum) is similar for thin and thick components, and of limited amplitude, and that stars of all components can be trapped at the corotation of the bar. At the exception of those stars trapped at the corotation, we find that stars that are far from their initial guiding radius are more likely so due to blurring rather than churning effects. We compare the simulation to orbits integration with a fixed gravitational potential rotating at a constant speed. In the latter case, stars trapped at corotation are churned periodically outside and inside the corotation radius, with a zero net average. However, as the bar speed of the simulated galaxy decreases and its corotation radius increases, stars trapped at corotation for several Gyrs can be churned outwards on average. We study the location of extreme migrators (stars experimenting the largest churning) and find that extreme migrators come from regions on the leading side of the effective potential local maxima.

description: Social pensions are important cash transfers to the elderly and their families. The pensions may not only affect the wellbeing of the direct recipients, but also have household and intergenerational spillover effects. Using the 2012 and 2014 waves of the China Family Panel Studies (CFPS) data, this paper examines the effect of the New Rural Pension Scheme (NRPS) and its mechanisms on child health in rural China. Our study shows a significant association between the NRPS and the health status of children up to 15 years of age. Moreover, the association of the NRPS with health is larger for children who are boys, ‘left behind’, six to 10 years of age, and in poor health. In addition, we investigate possible mechanisms of the effect, including health consciousness of the caregiver, household sanitation conditions, and high-protein food consumption, and find the increase of child nutrition intake is the main channel through which the NRPS affects child health.

description: We algebraically prove the cancellation of the beta function at all order of perturbation theory of N=2 supersymmetric gauge theories with a vanishing one-loop beta function. The proof generalises that recently given for the N=4 case. It uses the consistent Slavnov-Taylor identities of the shadow dependent formulation. We also demonstrate the cancellation at all orders of the anomalous dimensions of vector and hypermultiplet one half BPS operators.

description: Este artículo propone una crítica a uno de los elementos principales de la responsabilidad fiscal en Colombia a partir de la descripción de sus postulados normativos, los cuales se encuentran en la ley 610 de 2000 y 1474 de 20113. Aquí se expone que el dolo no tiene mucha utilidad en este tipo de procesos y tampoco la tiene el querer mantenerlo en el ordenamiento jurídico de responsabilidad fiscal ya que este es un título de imputación que ni agrava la conducta del gestor fiscal, ni la hace más efectiva en cuanto a la condición resarcitoria de la acción de responsabilidad fiscal. Por el contrario, la necesidad de probar su existencia en la conducta del funcionario sí limita la efectividad jurídica para el cobro de la póliza de seguro la cual es una de las herramientas más expeditas para lograr el objetivo de la responsabilidad fiscal, que finalmente es la protección del patrimonio público que puede lograrse a través del resarcimiento del daño.
description: This article proposes a critique of one of the main elements of fiscal responsibility in Colombia based on the description of its normative postulates, which are found in Law 610 of 2000 and Law 1474 of 2011. Here it is stated that fraud is not very useful in this type of process, and neither is wanting to keep it in the legal system of fiscal responsibility since this is an imputation title that neither aggravates the conduct of the fiscal manager nor makes it more effective in terms of the compensatory condition of the action for fiscal responsibility. On the contrary, the need to prove its existence in the conduct of the official does limit the legal effectiveness for the collection of the insurance policy, which is one of the most expeditious tools to achieve the objective of fiscal responsibility, which is ultimately the protection of public property that can be achieved through compensation for damage

description: The renormalization of the Wiedemann-Franz (WF) ratio in strongly correlated electron systems is analyzed within the Landau quasiparticle picture. We demonstrate that the WF law is violated: (i) at the quantum critical point, where the effective mass diverges, and (ii) beyond a point of fermion condensation, where the single-particle spectrum $ε(p)$ becomes flat. Results of the analysis are compared with available experimental data.

description: The generation and manipulation of entanglement between isolated particles has precipitated rapid progress in quantum information processing. Entanglement is also known to play an essential role in the optical properties of atomic ensembles, but fundamental effects in the controlled emission and absorption from small, well-defined numbers of entangled emitters in free space have remained unobserved. Here we present the control of the spontaneous emission rate of a single photon from a pair of distant, entangled atoms into a free-space optical mode. Changing the length of the optical path connecting the atoms modulates the emission rate with a visibility $V = 0.27 \pm 0.03$ determined by the degree of entanglement shared between the atoms, corresponding directly to the concurrence $\mathcal{C_ρ}= 0.31 \pm 0.10$ of the prepared state. This scheme, together with population measurements, provides a fully optical determination of the amount of entanglement. Furthermore, large sensitivity of the interference phase evolution points to applications of the presented scheme in high-precision gradient sensing.

description: We study the semileptonic decays of the $B_c$ meson into final charmonium states within the standard model and beyond. The relevant hadronic transition form factors are calculated in the framework of the covariant confined quark model developed by us. We focus on the tau mode of these decays, which may provide some hints of new physics effects. We extend the standard model by assuming a general effective Hamiltonian describing the $b\to cτν$ transition, which consists of the full set of the four-fermion operators. We then obtain experimental constraints on the Wilson coefficients corresponding to each operator and provide predictions for the branching fractions and other polarization observables in different new physics scenarios.

description: Background: Defibrillation in the critical first minutes of out-of-hospital cardiac arrest (OHCA) can significantly improve survival. However, timely access to automated external defibrillators (AEDs) remains a barrier.
Objectives: The authors estimated the impact of a statewide program for drone-delivered AEDs in North Carolina integrated into emergency medical service and first responder (FR) response for OHCA.
Methods: Using Cardiac Arrest Registry to Enhance Survival registry data, we included 28,292 OHCA patients ≥18 years of age between 1 January 2013 and 31 December 2019 in 48 North Carolina counties. We estimated the improvement in response times (time from 9-1-1 call to AED arrival) achieved by 2 sequential interventions: 1) AEDs for all FRs; and 2) optimized placement of drones to maximize 5-minute AED arrival within each county. Interventions were evaluated with logistic regression models to estimate changes in initial shockable rhythm and survival.
Results: Historical county-level median response times were 8.0 minutes (IQR: 7.0-9.0 minutes) with 16.5% of OHCAs having AED arrival times of <5 minutes (IQR: 11.2%-24.3%). Providing all FRs with AEDs improved median response to 7.0 minutes (IQR: 6.2-7.8 minutes) and increased OHCAs with <5-minute AED arrival to 22.3% (IQR: 16.4%-30.9%). Further incorporating optimized drone networks (326 drones across all 48 counties) improved median response to 4.8 minutes (IQR: 4.3-5.2 minutes) and OHCAs with <5-minute AED arrival to 56.3% (IQR: 46.9%-64.2%). Survival rates were estimated to increase by 34% for witnessed OHCAs with estimated drone arrival <5 minutes and ahead of FR and emergency medical service.
Conclusions: Deployment of AEDs by FRs and optimized drone delivery can improve AED arrival times which may lead to improved clinical outcomes. Implementation studies are needed.

description: To implement fault-tolerant quantum computation with continuous variables, the Gottesman-Kitaev-Preskill (GKP) qubit has been recognized as an important technological element. However,it is still challenging to experimentally generate the GKP qubit with the required squeezing level, 14.8 dB, of the existing fault-tolerant quantum computation. To reduce this requirement, we propose a high-threshold fault-tolerant quantum computation with GKP qubits using topologically protected measurement-based quantum computation with the surface code. By harnessing analog information contained in the GKP qubits, we apply analog quantum error correction to the surface code.Furthermore, we develop a method to prevent the squeezing level from decreasing during the construction of the large scale cluster states for the topologically protected measurement based quantum computation. We numerically show that the required squeezing level can be relaxed to less than 10 dB, which is within the reach of the current experimental technology. Hence, this work can considerably alleviate this experimental requirement and take a step closer to the realization of large scale quantum computation.
