description: The precise modeling of the de-excitation of Gd isotopes is of great interest for experimental studies of neutrinos using Gd-loaded organic liquid scintillators. The FIFRELIN code was recently used within the purposes of the STEREO experiment for the modeling of the Gd de-excitation after neutron capture in order to achieve a good control of the detection efficiency. In this work, we report on the recent additions in the FIFRELIN de-excitation model with the purpose of enhancing further the de-excitation description. Experimental transition intensities from EGAF database are now included in the FIFRELIN cascades, in order to improve the description of the higher energy part of the spectrum. Furthermore, the angular correlations between γ rays are now implemented in FIFRELIN, to account for the relative anisotropies between them. In addition, conversion electrons are now treated more precisely in the whole spectrum range, while the subsequent emission of X rays is also accounted for. The impact of the aforementioned improvements in FIFRELIN is tested by simulating neutron captures in various positions inside the STEREO detector. A repository of up-to-date FIFRELIN simulations of the Gd isotopes is made available for the community, with the possibility of expanding for other isotopes which can be suitable for different applications.

description: This study explored the association between psychological strengths and perceptions of being a victim of a bullying relationship in the school environment. Using self-report questionnaires with grades 7 and 8 students, the role of psychological strengths as potential protective factors against various forms of bullying were examined including the patterns of strengths associated with the bullying experience. The results showed no significant association between global indices of strengths and perceptions of victimization. However, significant relationships did emerge between specific strengths and victimization. Strengths in school functioning among boys but not girls and strengths in personality functioning for both sexes were associated with lower perceived victimization. In contrast, strengths in spiritual and cultural identification were associated with perceptions of increased victimization. The implications of these results for anti-bullying strategies are discussed. Cette étude a porté sur l'association entre les forces psychologiques et les perceptions d'être victime d'intimidation à l'école. En nous appuyant sur des questionnaires d'auto-évaluation auprès d'élèves en 7e et 8e année, nous avons examiné le rôle des forces psychologiques comme facteurs potentiels de protection contre diverses formes d'intimidation. L'étude a également porté sur les modèles de forces associés à l'expérience de l'intimidation. Les résultats n'ont indiqué aucune association entre les indices globaux de forces et les perceptions de l'intimidation. Toutefois, des relations significatives sont ressorties entre des forces spécifiques et l'intimidation. Des forces relatives à l'école chez les garçons mais pas les filles, et des forces relatives à la personnalité chez les garçons et les filles, étaient associées à une perception amoindrie de la victimisation. Par contre, des forces relatives à l'identification spirituelle et culturelle étaient associées à des perceptions accrues de victimisation. Nous discutons des répercussions de ces résultats sur les stratégies contre l'intimidation.

description: We revisit the hybrid inflation model focusing on the dynamics of the waterfall field in an analytical way. It is shown that inflation may last long enough during the waterfall regime for some parameter regions, confirming the claim of Clesse. In this case the scalar spectral index becomes red, and can fall into the best fit range of the WMAP observation.

The Effect of Missing Data Treatment on Mantel-Haenszel DIF Detection

description: Most implementations of the Mantel-Haenszel differential item functioning procedure delete records with missing responses or replace missing responses with scores of 0. These treatments of missing data make strong assumptions about the causes of the missing data. Such assumptions may be particularly problematic when groups differ in their patterns of nonresponse. Using both real data from Ontario students taking the English- and French-language versions of two large-scale assessments and simulated data, this study compared the Mantel-Haenszel DIF indices produced using a total score or a proportion score as matching variables and treating missing data by listwise deletion, analysiswise deletion, or scoring missing data as incorrect. The results suggest that when many responses are missing, differential nonresponse rates may be a source of DIF. La plupart des mises en oeuvre de la méthode du fonctionnement différentiel des items de MantelHaenszel suppriment les observations ayant des réponses qui manquent ou bien elles remplacent les réponses manquantes par un 0. Ces façons de traiter l'information manquante repose sur des hypothèses quant aux causes des lacunes, hypothèses qui pourraient s'avérer particulièrement inquiétantes quand l'absence de réponse chez les différents groupes suit un schéma distinct. En nous appuyant tant sur des données réelles d'élèves de l'Ontario ayant passé les versions en anglais et en français de deux évaluations à grande échelle, que sur des données simulées, nous avons comparé les indices de la méthode du fonctionnement différentiel des items de MantelHaenszel produits par l'emploi d'un score total ou d'un score de proportion comme variables appariées et en traitant les données manquantes de trois façons : suppression de toutes les observations comportant au moins une valeur manquante; calcul de la corrélation pour chaque couple de variables à partir des données disponibles; ou considération des données manquantes comme des erreurs. Les résultats portent à croire que lorsqu'il manque plusieurs réponses, les taux différentiels d'absence de réponse peuvent constituer une source de fonctionnement différentiel des items.

Compra de recursos electrónicos

description: La crisis afecta a las bibliotecas públicas (sean estas científicas o no) del mismo modo que a cualquier servicio de la Administración: la caída de ingresos por parte del Estado tiene como consecuencia el recorte del presupuesto que recibe de este. Se ven afectados desde la contratación de personal hasta el mantenimiento de las instalaciones. Y de un modo muy sensible, las colecciones de información. La colección ha experimentado extraordinarios cambios en la última década: ha migrado al soporte digital, ha crecido espectacularmente en número de títulos (revistas, libros y otros contenidos) y está disponible para los usuarios sin necesidad de que estos acudan al espacio físico “biblioteca”. El coste económico ha sido grande. El incremento del uso de la colección también. Sin embargo, no es posible ni razonable el crecimiento indefinido de la colección, por ello – y más estando inmersos en la crisis actual- en la Red de Bibliotecas del CSIC desde hace al menos 3 años se han tomado medidas para frenar el gasto en información científica, tanto en lo que se refiere a las suscripciones propias de cada centro o instituto como en los recursos que se contratan centralizadamente para toda la institución. Hay que profundizar en este camino: limitar la colección a lo que más se usa mientras se demanda a los proveedores de información científica que también ellos reduzcan el coste de la misma. Estamos ante un cambio de modelo en el que hay que preocuparse, además, de la preservación de los contenidos digitales que dejen de contratarse, de los beneficios que la colección puede obtener de las publicaciones en OA, y en el que tendrá más importancia que nunca la cooperación entre bibliotecas para compartir recursos.

description: We explore the extent to which two quantum oscillators can exchange their quantum states efficiently through a three-level system which can be spin levels of colored centers in solids. High transition probabilities are obtained using Hamiltonian engineering and quantum control techniques. Starting from a weak coupling approximation, we derive conditions on the spin-oscillator interaction Hamiltonian that enable a high-fidelity exchange of quanta. We find that these conditions cannot be fulfilled for arbitrary spin-oscillator coupling. To overcome this limitation, we illustrate how a time-dependent control field applied to the three-level system can lead to an effective dynamic that performs the desired exchange of excitation. In the (ultra) strong coupling regime, an important loss of fidelity is induced by the dispersion of the excitation onto many Fock states of the oscillators. We show that this detrimental effect can be substantially reduced by suitable control fields, which are computed with optimal control numerical algorithms.

description: The radionuclide 22Na is a potential astronomical observable that is expected to be produced in classical novae in quantities that depend on the thermonuclear rate of the 22Na(p,g)23Mg reaction. We have measured the strengths of low-energy 22Na(p,g)23Mg resonances directly and absolutely using a radioactive 22Na target. We find the strengths of resonances at E_p = 213, 288, 454, and 610 keV to be higher than previous measurements by factors of 2.4 to 3.2, and we exclude important contributions to the rate from proposed resonances at E_p = 198, 209, and 232 keV. The 22Na abundances expected in the ejecta of classical novae are reduced by a factor of ~ 2.

description: Dark matter (DM) nature is one of the major issues in physics. The search for a DM candidate has motivated the known proposal of an ultralight scalar field (ULSF). We explore the possibility to search for this ULSF at the upcoming European Spallation Source neutrino Super-Beam experiment. We have considered the recent study case in which there could be an interaction between the ULSF and active neutrinos. We have found that in this future experimental setup, the sensitivity is competitive with other neutrino physics experiments. We show the expected future sensitivity for the main parameter modeling the interaction between ULSF and neutrinos.

Year: 2011

description: The purpose of this study was to explore to what extent 87 grade 5 (10-12-year-old) children, supported by instruction about scientific models, could engage in thinking beyond a naïve realist level about a globe. A qualitative framework allowed analysis of children’s responses to worksheet questions in which they identified analog-target correspondence and how models act as tools for thinking. Children’s responses were further analyzed using visual factors (Goldsmith, 1984) and interacting components (Mathewson, 2005) organized to highlight semiotic challenges associated with the models. The data demonstrated a beginning sophistication in thinking about models that for more than half the children was beyond a naïve realist level. Further research with children working with models of less familiar targets and multiple models of the same target is recommended. Cette étude avait comme objectif d’explorer dans quelle mesure 87 élèves de la 5e année (10 à 12 ans) appuyés par un enseignement sur les modèles scientifiques, pouvaient réfléchir au sujet d’un globe au-delà du niveau du réalisme naïf. Un cadre qualitatif a permis l’analyse des réponses qu’ont fournies les enfants à des questions portant sur l’identification de la correspondance analogique et les modèles en tant qu’outils de réflexion. Les réponses des élèves ont également été analysées selon des facteurs visuels (Goldsmith, 1984) et des composantes interdépendantes (Mathewson, 2005) organisées de sorte à faire ressortir les défis sémiotiques associés aux modèles. Les données ont démontré un début de réflexion sophistiquée sur les modèles qui, chez plus de la moitié des enfants, dépassait le niveau du réalisme naïf. Nous recommandons de poursuivre la recherche avec des enfants qui travaillent avec des modèles de cibles moins connues et avec plusieurs modèles de la même cible.

description: This report describes the effect of cooperative learning in low-track and regular classrooms, using the dimensions of student alienation, academic self-esteem, willingness to cooperate, and academic supportiveness. The investigators examined the influence of student agency in choosing peers for the cooperative groups in a high school science classroom. Results indicate that the ability for low-track students to choose group mates can result in greater feelings of alienation, have no effect on bolstering a lower academic self-esteem, and reduce willingness to cooperate with peers. Regardless of stream, students did not feel academically supported by peers in the classroom. Recommendations for using cooperative learning and coping with educational reform are discussed. Ce rapport décrit l'effet de l'apprentissage coopératif dans des salles de classe d'éducation spécialisée et des salles de classe régulières et ce, sous l'optique de la marginalisation des élèves, l'estime de soi sur le plan académique, la volonté de coopérer et le soutien académique. Les chercheurs ont examiné l'influence de l'action par les étudiants dans le choix de pairs pour les groupes coopératifs dans un cours de science à l'école secondaire. Les résultats indiquent que la capacité qu'ont les élèves de la voie éducation spécialisée à choisir des partenaires de groupe peut entrainer les effets suivants : augmentation du sentiment de marginalisation; aucun rehaussement du faible estime de soi sur le plan académique; et diminution de la volonté de collaborer avec les pairs. Les élèves dans les deux voies ne sentaient pas d'appui académique de la part de leurs pairs en classe. Nous discutons de recommandations pour l'emploi de l'apprentissage coopératif et pour la gestion de la réforme de l'enseignement.

description: We study the Hall response of the Bose-Hubbard model subjected to a magnetic field. We show that the Hall conductivity is proportional to the particle density plus an integer. The phase diagram is intersected by topological transitions between different integer values. These transitions originate from points in the phase diagram with effective charge conjugation symmetry, and are attributed to degeneracies in the many body spectrum which serve as sources for the Berry curvature. We find that extensive regions in the phase diagram exhibit a negative Hall conductivity, implying that flux flow is reversed in these regions - vortices there flow upstream. We discuss experimental implications of our findings.

description: External diagnosis is recommended when schools lack the capacity to assess their needs. This qualitative study of one Ontario district compared 33 elementary schools that conducted external diagnosis with 47 schools that used internal diagnosis. External diagnosis created pressure for change, helped schools develop a plan that included previously neglected needs, promoted consistency within and between schools, contributed to the improvement culture of the school, and encouraged shared instructional leadership. It also depressed teacher efficacy and commitment to school improvement. Positive effects of external diagnosis were facilitated and negative effects mitigated by principals who adopted shared instructional leadership strategies. L'on recommande une analyse externe quand les écoles n'ont pas la capacité d'évaluer leurs besoins. Cette étude qualitative d'un district en Ontario porte sur une comparaison entre 33 écoles élémentaires qui ont entrepris un diagnostic externe et 47 écoles qui ont eu recours à un diagnostic interne. Les diagnostics externes ont créé une pression pour le changement, aidé les écoles à développer un projet qui incluait des besoins auparavant négligés, favorisé la cohérence à l'intérieur des écoles et entre elles, contribué à la culture d'amélioration de l'école et encouragé le partage du leadership de l'enseignement. Ils ont également diminué l'efficacité des enseignants et leur engagement face à l'amélioration de l'école. Les effets positifs des diagnostics externes ont été facilités et les effets négatifs mitigés par les directeurs qui ont adopté des stratégies de partage du leadership de l'enseignement.

description: This article analyzes a social-justice teacher education project in a larger teacher education program in Western Canada. This program-within-a-program took an anti-oppressive education approach designed to help teacher candidates to understand and challenge various forms of inequity and their interconnections. We review the social justice project first, through a descriptive analysis of our teaching, and second, through hour-long qualitative, semistructured interviews with 20 graduates of our program (all beginning teachers). Our alumni provided examples of teaching against the grain and also spoke to the challenges of implementing critical pedagogies. We conclude by providing four key recommendations and reflecting on the implications for future teacher preparation. Cet article analyse un projet de justice sociale dans le cadre d’un important programme de formation des enseignants dans l’Ouest canadien. Ce « programme à l’intérieur d’un programme » a adopté une approche pédagogique contre l’oppression, conçue pour aider les étudiants en pédagogie à comprendre et à remettre en question diverses formes d’iniquité et les liens entre elles. Nous nous penchons sur le programme de justice sociale, d’abord par une analyse descriptive de notre enseignement, ensuite par des entrevues qualitatives et semi-structurées d’une heure auprès de finissants de notre programme (tous débutant leur carrière d’enseignant). Nos anciens ont fourni des exemples d’enseignement à contre-courant et ont évoqué les défis liés à la mise en oeuvre de pédagogies critiques. Nous concluons en présentant quatre recommandations clés et en réfléchissant aux conséquences pour la formation des enseignants à l’avenir.

description: Asynchronous Many-Task (AMT) runtime systems take advantage of multi-core architectures with light-weight threads, asynchronous executions, and smart scheduling. In this paper, we present the comparison of the AMT systems Charm++ and HPX with the main stream MPI, OpenMP, and MPI+OpenMP libraries using the Task Bench benchmarks. Charm++ is a parallel programming language based on C++, supporting stackless tasks as well as light-weight threads asynchronously along with an adaptive runtime system. HPX is a C++ library for concurrency and parallelism, exposing C++ standards conforming API. First, we analyze the commonalities, differences, and advantageous scenarios of Charm++ and HPX in detail. Further, to investigate the potential overheads introduced by the tasking systems of Charm++ and HPX, we utilize an existing parameterized benchmark, Task Bench, wherein 15 different programming systems were implemented, e.g., MPI, OpenMP, MPI + OpenMP, and extend Task Bench by adding HPX implementations. We quantify the overheads of Charm++, HPX, and the main stream libraries in different scenarios where a single task and multi-task are assigned to each core, respectively. We also investigate each system's scalability and the ability to hide the communication latency.

description: Data-to-text (D2T) generation is a crucial task in many natural language understanding (NLU) applications and forms the foundation of task-oriented dialog systems. In the context of conversational AI solutions that can work directly with local data on the user's device, architectures utilizing large pre-trained language models (PLMs) are impractical for on-device deployment due to a high memory footprint. To this end, we propose TrICy, a novel lightweight framework for an enhanced D2T task that generates text sequences based on the intent in context and may further be guided by user-provided triggers. We leverage an attention-copy mechanism to predict out-of-vocabulary (OOV) words accurately. Performance analyses on E2E NLG dataset (BLEU: 66.43%, ROUGE-L: 70.14%), WebNLG dataset (BLEU: Seen 64.08%, Unseen 52.35%), and our Custom dataset related to text messaging applications, showcase our architecture's effectiveness. Moreover, we show that by leveraging an optional trigger input, data-to-text generation quality increases significantly and achieves the new SOTA score of 69.29% BLEU for E2E NLG. Furthermore, our analyses show that TrICy achieves at least 24% and 3% improvement in BLEU and METEOR respectively over LLMs like GPT-3, ChatGPT, and Llama 2. We also demonstrate that in some scenarios, performance improvement due to triggers is observed even when they are absent in training.

description: Positive teacher-student relationship has been established as an important contributor to students' social, behavioral, and academic adjustment. Nevertheless, current research has not employed relationship measures that examine both teachers' and students' perceptions. Furthermore, the measures currently being used lack breadth in the definition of the teacher-student relationship. Using the construct of "working alliance" from counseling psychology, this study investigated teachers' (n=14) and elementary school students' (n=53) perceptions of their working alliance and explored how this construct relates to student performance. Teachers' and students' ratings on subscales of the Classroom Working Alliance Inventory (CWAI) were found to be significantly related to one another. In addition, regression analyses demonstrated that both teachers' and students' ratings of working alliance contributed significantly to ratings on the Student Performance Questionnaire (SPQ). Un rapport positif entre l'enseignant et l'élève s'est avéré être un facteur important qui contribue à l'adaptation sociale, comportementale et académique des élèves. Néanmoins, la recherche actuelle n'a pas employé de mesures des rapports qui examinent à la fois les perceptions des enseignants et celles des élèves. De plus, les mesures actuelles manquent d'envergure quant à leur définition du rapport enseignant-élève. Empruntant de la psychologie thérapeutique la construction de l'alliance de travail, nous avons étudié les perceptions qu'ont les enseignants (n=14) et les élèves de l'élémentaire (n=53) de leur alliance de travail et avons examiné dans quelle mesure cette construction joue un rôle dans le rendement des élèves. Nous avons trouvé une relation significative entre les cotes des enseignants et celles des élèves aux sous-échelles de l'inventaire de l'alliance de travail en salle de classe (Classroom Working Alliance Inventory). De plus, les analyses de régression ont démontré que ces cotes, tant celles des enseignants que celles des élèves, ont contribué de façon significative aux cotes du questionnaire sur le rendement des élèves.

description: The object of research is the development and study of a method for digital signal processing. During the development, the Matlab / Simulink simulation tool was used. The main methods of digital signal processing in radio navigation systems, which are now widely used in sea and river navigation, were considered. The method of digital signal processing based on the Hilbert displacement was modified in order to improve the navigation accuracy in narrows, fairways, channels. The result of this work is a simulation model that allows evaluating the result of digital processing of signals from a radio navigation system.
Gravity modes in rapidly rotating stars. Limits of perturbative methods

description: CoRoT and Kepler missions are now providing high-quality asteroseismic data for a large number of stars. Among intermediate-mass and massive stars, fast rotators are common objects. Taking the rotation effects into account is needed to correctly understand, identify, and interpret the observed oscillation frequencies of these stars. A classical approach is to consider the rotation as a perturbation. In this paper, we focus on gravity modes, such as those occurring in gamma Doradus, slowly pulsating B (SPB), or Be stars. We aim to define the suitability of perturbative methods. With the two-dimensional oscillation program (TOP), we performed complete computations of gravity modes -including the Coriolis force, the centrifugal distortion, and compressible effects- in 2-D distorted polytropic models of stars. We started with the modes l=1, n=1-14, and l=2-3, n=1-5,16-20 of a nonrotating star, and followed these modes by increasing the rotation rate up to 70% of the break-up rotation rate. We then derived perturbative coefficients and determined the domains of validity of the perturbative methods. Second-order perturbative methods are suited to computing low-order, low-degree mode frequencies up to rotation speeds ~100 km/s for typical gamma Dor stars or ~150 km/s for B stars. The domains of validity can be extended by a few tens of km/s thanks to the third-order terms. For higher order modes, the domains of validity are noticeably reduced. Moreover, perturbative methods are inefficient for modes with frequencies lower than the Coriolis frequency 2Omega. We interpret this failure as a consequence of a modification in the shape of the resonant cavity that is not taken into account in the perturbative approach.

Aspects of quantum information in quantum field theory and quantum gravity
Creators: name: Neuenfeld, Dominik
Publisher: name: University of British Columbia
Year: 2019

description: In this thesis we discuss applications of quantum information theoretic concepts to quantum gravity and the low-energy regime of quantum field theories. The first part of this thesis is concerned with how quantum information spreads in four-dimensional scattering experiments for theories coupled to quantum electrodynamics or perturbative quantum gravity. In these cases, every scattering process is accompanied by the emission of an infinite number of soft photons or gravitons, which cause infrared divergences in the calculation of scattering probabilities. There are two methods to deal with IR divergences: the inclusive and dressed formalisms. We demonstrate that in the late-time limit, independent of the method, the hard outgoing particles are entangled with soft particles in such a way that the reduced density matrix of the hard particles is essentially completely decohered. Furthermore, we show that the inclusive formalism is ill-suited to describe scattering of wavepackets, requiring the use of the dressed formalism. We construct the Hilbert space for QED in the dressed formalism as a representation of the canonical commutation relations of the photon creation/annihilation algebra, and argue that it splits into superselection sectors which correspond to eigenspaces of the generators of large gauge transformations. In the second part of this thesis, we turn to applications of quantum information theoretic concepts in the AdS/CFT correspondence. In pure AdS, we find an explicit formula for the Ryu-Takayanagi (RT) surface for special subregions in the dual conformal field theory, whose entangling surface lie on a light cone. The explicit form of the RT surface is used to give a holographic proof of Markovicity of the CFT vacuum on a light cone. Relative entropy of a state on such special subregions is dual to a novel measure of energy associated with a timelike vector flow between the causal and entanglement wedge. Positivity and monotonicity of relative entropy imply positivity and monotonicity of this energy, which yields a consistency conditions for solutions to quantum gravity.

description: We report a first-principles study of static transport of localized waves in quasi-one-dimensional open media. We found that such transport, dominated by disorder-induced resonant transmissions, displays novel diffusive behavior. Our analytical predictions are entirely confirmed by numerical simulations. We showed that the prevailing self-consistent localization theory [van Tiggelen, {\it et. al.}, Phys. Rev. Lett. \textbf{84}, 4333 (2000)] is valid only if disorder-induced resonant transmissions are negligible. Our findings open a new direction in the study of Anderson localization in open media.

Non-Hermitian skin effect in one-dimensional interacting Bose gas

description: Non-Hermitian skin effect (NHSE) is a unique feature studied extensively in non-interacting non-Hermitian systems. In this work, we extend the NHSE originally discovered in non-interacting systems to interacting many-body systems by investigating an exactly solvable non-Hermitian model, i.e., the prototypical Lieb-Liniger Bose gas with imaginary vector potential. We show that this non-Hermitian many-body model can also be exactly solved through Bethe ansatz. By solving the Bethe ansatz equations accurately, the explicit eigenfunction is obtained, and the model's density profiles and momentum distributions are calculated to characterize the NHSE quantitatively. We find that the NHSE is gradually suppressed on the repulsive side but does not vanish as the repulsive interaction strength increases. On the attractive side, the NSHE for bound-state solutions is enhanced as interaction strength grows. In contrast, for the scattering state the NHSE shows a non-monotonic behavior in the attractive side. Our work provides the first example of the NHSE in exactly solvable many-body systems, and we envision that it can be extended to other non-Hermitian many-body systems, especially to integrable models.
