description: We study the 2D Ginzburg-Landau theory for a type-II superconductor in an applied magnetic field varying between the second and third critical value. In this regime the order parameter minimizing the GL energy is concentrated along the boundary of the sample and is well approximated to leading order by a simplified 1D profile in the direction perpendicular to the boundary. Motivated by a conjecture of Xing-Bin Pan, we address the question of whether this approximation can hold uniformly in the boundary region. We prove that this is indeed the case as a corollary of a refined, second order energy expansion including contributions due to the curvature of the sample. Local variations of the GL order parameter are controlled by the second order term of this energy expansion, which allows us to prove the desired uniformity of the surface superconductivity layer.

description: In wearable sensing applications, data is inevitable to be irregularly sampled or partially missing, which pose challenges for any downstream application. An unique aspect of wearable data is that it is time-series data and each channel can be correlated to another one, such as x, y, z axis of accelerometer. We argue that traditional methods have rarely made use of both times-series dynamics of the data as well as the relatedness of the features from different sensors. We propose a model, termed as DynImp, to handle different time point's missingness with nearest neighbors along feature axis and then feeding the data into a LSTM-based denoising autoencoder which can reconstruct missingness along the time axis. We experiment the model on the extreme missingness scenario ($>50\%$ missing rate) which has not been widely tested in wearable data. Our experiments on activity recognition show that the method can exploit the multi-modality features from related sensors and also learn from history time-series dynamics to reconstruct the data under extreme missingness.

description: Based on a regular exact black hole (BH) from nonlinear electrodynamics (NED) coupled to General Relativity, we investigate its stability of such BH through the Quasinormal Modes (QNMs) of electromagnetic (EM) field perturbation and its thermodynamics through Hawking radiation. In perturbation theory, we can deduce the effective potential from nonlinear EM field. The comparison of potential function between regular and RN BHs could predict their similar QNMs. The QNMs frequencies tell us the effect of magnetic charge $q$, overtone $n$, angular momentum number $l$ on the dynamic evolution of NLED EM field. Furthermore we also discuss the cases near extreme condition of such magnetically charged regular BH. The corresponding QNMs spectrum illuminates some special properties in the near-extreme cases. For the thermodynamics, we employ Hamilton-Jacobi method to calculate the near-horizon Hawking temperature of the regular BH and reveal the relationship between classical parameters of black hole and its quantum effect.

description: Frequent accretion of external cold gas is thought to play an important role in galaxy assembly. However, almost all known kinematically misaligned galaxies identify only one gas disk that is misaligned with the stellar disk, implying a single gas acquisition event. Here we report a new configuration in two galaxies where both contain two gas disks misaligned with each other and also with the stellar disk. Such systems are not expected to be stable or long-lasting, challenging the traditional picture of gas accretion of galaxies and their angular momentum build-up. The differences in kinematic position angles are larger than 120° between the two gas disks, and 40° between each gas disk and the stellar component. The star formation activity is enhanced at the interface of the two gas disks compared with the other regions within the same galaxy. Such systems illustrate that low-redshift galaxies can still experience multiple gas acquisition events, and provide a new view into the origins of galactic gas.

description: In der Arbeit wird der Versuch unternommen, die lange Entwicklungsgeschichte des Blasphemiedelikts bis hinein in die Rechtsordnung der Bundesrepublik Österreich und der Katholischen Kirche nachzuzeichnen. In der Arbeit zeigt sich, dass das Delikt als eine Grenze gesehen werden kann, an welcher das Selbstverständnis des Staates, der in ihm vorherrschenden Religionen sowie der Gesellschaft verhandelt wird. Die Arbeit gibt daher einen Einblick in die Religionssysteme der antiken Welt und möchte aufzeigen, auf welche Weise damals Religion, Staat und Gesellschaft verbunden waren. Hiervon ausgehend werden zwei zentrale Motive für die Verfolgung von Gotteslästerer erklärt, nämlich die Vorstellung vom Zorn der Götter und die Sicherung der ‚pax deorum‘ als Aufgabe des Herrschers. Weiters wendet sich die Arbeit dem Thema der religiösen Polemik zu. Den Ausgangspunkt dieses Kapitels bildet die These des Ägyptologen Jan Assmann, nach welcher sich ‚Sekundärreligionen‘ wie das Christentum mittels einer abwertenden Sprache nach außen hin abgrenzen müssen, um nach innen hin Identität und Gemeinschaft zu stiften Letztlich wird in der Arbeit ausführlich die geschichtliche Entwicklung des Blasphemiedelikts, ausgehend von seinen Wurzeln im Römischen Recht und im Christentum, erarbeitet. Es werden hierzu einschlägige Quellen des Rechts und der Theologie herangezogen, um nachzuzeichnen, wie der heutige § 188 StGB und der c. 1368 CIC einerseits Eingang in die Rechtsordnungen des Staates und der Katholischen Kirche gefunden haben und andererseits, auf welche Weise der Staat und die Kirche an der konkreten Ausgestaltung der Delikte Anteil hatten.

description: Strong convergence rates for (temporal, spatial, and noise) numerical approximations of semilinear stochastic evolution equations (SEEs) with smooth and regular nonlinearities are well understood in the scientific literature. Weak convergence rates for numerical approximations of such SEEs have been investigated since about 11 years and are far away from being well understood: roughly speaking, no essentially sharp weak convergence rates are known for parabolic SEEs with nonlinear diffusion coefficient functions; see Remark 2.3 in [A. Debussche, Weak approximation of stochastic partial differential equations: the nonlinear case, Math. Comp. 80 (2011), no. 273, 89-117] for details. In this article we solve the weak convergence problem emerged from Debussche's article in the case of spectral Galerkin approximations and establish essentially sharp weak convergence rates for spatial spectral Galerkin approximations of semilinear SEEs with nonlinear diffusion coefficient functions. Our solution to the weak convergence problem does not use Malliavin calculus. Rather, key ingredients in our solution to the weak convergence problem emerged from Debussche's article are the use of appropriately modified versions of the spatial Galerkin approximation processes and applications of a mild Itô type formula for solutions and numerical approximations of semilinear SEEs. This article solves the weak convergence problem emerged from Debussche's article merely in the case of spatial spectral Galerkin approximations instead of other more complicated numerical approximations. Our method of proof extends, however, to a number of other kind of spatial, temporal, and noise numerical approximations for semilinear SEEs.

description: A method based on laser wakefield acceleration with controlled ionization injection triggered by another frequency-tripled laser is proposed, which can produce electron bunches with low energy spread. As two color pulses co-propagate in the background plasma, the peak amplitude of the combined laser field is modulated in time and space during the laser propagation due to the plasma dispersion. Ionization injection occurs when the peak amplitude exceeds certain threshold. The threshold is exceeded for limited duration periodically at different propagation distances, leading to multiple ionization injections and separated electron bunches. The method is demonstrated through multi-dimensional particle-in-cell simulations. Such electron bunches may be used to generate multi-chromatic X-ray sources for a variety of applications.

description: Until now, no simple symmetries have been detected in complex networks. Here we show that, in growing multiplex networks the symmetries of multilayer structures can be exploited by their dynamical rules, forming supersymmetric multiplex networks described by coupled Bose-Einstein and Fermi-Dirac quantum statistics. The supersymmetric multiplex is formed by layers which are scale-free networks and can display a Bose-Einstein condensation of the links. To characterize the complexity of the supersymmetric multiplex using quantum information tools, we extend the definition of the network entanglement entropy to the layers of multiplex networks. Interestingly we observe a very simple relation between the entanglement entropies of the layers of the supersymmetric multiplex network and the entropy rate of the same multiplex network. This relation therefore connects the classical non equilibrium growing dynamics of the supersymmetric multiplex network with its quantum information static characteristics.

In this way, we analyze time-dependent populations of photon-number states and quantum statistics on the base of second-order photon correlation function in one-photon and two-photon transitions. The effects coming from thermal reservoirs are interesting for performing more realistic approach to generate Fock states and for study phenomena connecting quantum engineering and temperature. We also study the role of pulse-shaping effects during selective excitation.

description: We use standard tools of Archaeoastronomy to approach the study of orientations, possibly astronomical, of a group of colonial Christian churches. We present preliminary results of the analysis of the precise spatial orientation of nearly fifty chapels and churches of the Canary Island of Fuerteventura (Spain), most of them built from the period of the Norman conquest in the fifteenth century to the nineteenth century. Although some small chapels belonging to the manorial power of the island and other modern churches do not have a well-defined pattern of orientations, the vast majority of the religious constructions of the island (about 35 of the 48 analyzed) have their axis oriented within the solar range, between the extreme azimuths of the annual movement of the Sun when crossing the local horizon. Unlike what was found in other islands of the archipelago, these results suggest that the religious architecture of Fuerteventura faithfully follows the prescriptions contained in the texts of early Christian writers.

description: Neutrinoless double-$β$ ($0νββ$) decay is related to many fundamental concepts in nuclear and particle physics beyond the standard model. Currently there are many experiments searching for this weak process. An accurate knowledge of the nuclear matrix element for the $0νββ$ decay is essential for determining the effective neutrino mass once this process is eventually measured. We report the first full relativistic description of the $0νββ$ decay matrix element based on a state-of-the-art nuclear structure model. We adopt the full relativistic transition operators which are derived with the charge-changing nucleonic currents composed of the vector coupling, axial-vector coupling, pseudoscalar coupling, and weak-magnetism coupling terms. The wave functions for the initial and final nuclei are determined by the multireference covariant density functional theory (MR-CDFT) based on the point-coupling functional PC-PK1. The low-energy spectra and electric quadrupole transitions in ${}^{150}$Nd and its daughter nucleus ${}^{150}$Sm are well reproduced by the MR-CDFT calculations. The $0νββ$ decay matrix elements for both the $0_1^+\rightarrow 0_1^+$ and $0_1^+\rightarrow 0_2^+$ decays of ${}^{150}$Nd are evaluated. The effects of particle number projection, static and dynamic deformations, and the full relativistic structure of the transition operators on the matrix elements are studied in detail. The resulting $0νββ$ decay matrix element for the $0_1^+\rightarrow 0_1^+$ transition is $5.60$, which gives the most optimistic prediction for the next generation of experiments searching for the $0νββ$ decay in ${}^{150}$Nd.

description: Giriş ve Amaç: Subjektif bellek yakınması (SBY) bilişsel bozulma olmaksızın kişide unutkanlık yakınması olmasıdır. Prevalansı yaşla birlikte artarak %60’ları bulabilir. Bu güne kadar SBY olgularında yapılan çalışmalarda; kontrollere göre Alzheimer hastalığı (AH) için önemli bir risk faktörü olan homozigot APOE-ε4 taşıyıcılığının daha fazla olduğu gösterilmiştir (1). Ancak SMC olgularının kontrollerden ayıran komorbid durumlar konusunda henüz yeterli çalışma yoktur. Bu hedefle 'Alzheimer's Disease Neuroimaging Initiative' (ADNI)'ye kayıtlı SMC olguları ile aynı veri tabanına kayıtlı kontrol gurubunun verileri karşılaştırılarak komorbidite farklarının ortaya konulması amaçlanmıştır. Metod: ADNI’ye kayıtlı bilişsel açıdan normal, en az iki yıllık takibi olan ve komorbid hastalıkları kaydedilmiş, SBY ve kontrol olguları çalışmaya dâhil edilerek iki grubun özellikleri birbiri ile karşılaştırıldı. Sonuçlar: Toplam 72 SBY ve 68 kontrol olgusunun yaş ortalaması sırası ile 71±5, 70±4 yıldı. Kontrol olgularının %3’ünde 44±23 ay, SBY olgularının ise %10’unda 21±16 ayda demans gelişmiştir. Sonuçlar istatiksel olarak anlamlıdır. AH gelişen SBY ve kontrol olgularında depresyon, hipertansiyon, hiperlipidemi, renal yetmezlik, glokom, işitme azlığı, inme, anksiyete bozukluğu, vitamin D ve vitamin B12 eksikliği açısından istatiksel fark bulunamamıştır. Kontrolllerde %2, SMC olgularında %13 oranında görülen Tip II diyabetes mellitus (DM) ve kontrollerde %2, SMC olgularında %14 oranında saptanan insomni ise istatiksel anlamlılığa yansıyacak şekilde farklı olarak saptanmıştır. Tartışma: Çalışmamızda SBY olgularında, benzer yaş grubundakilere göre AH gelişme riskinin fazla olduğu ve DM’nin de bir risk faktörü olabileceği sonuçlarına ulaşılmıştır. DM’nin AH için bir risk faktörü olduğu ve prognozu etkileyebileceği bilinmektedir (2). Sonuçlarımıza yansıyan insomninin SBY’den AH’ye dönüşümde bir katkısı olabileceğini gösteren bilimsel bir veriye daha önce rastlanmamıştır. Daha fazla sayıda hasta içeren çalışmalar gereklidir.
title: Wie fördert das Modell der Bewegungslandschaft und der Bewegungsbaustelle die sensorische Integration der Nahsinne bei Kindern im Vorschulalter

description: In dieser Arbeit beschäftigt sich die Verfasserin mit den drei Nahsinnen, Gleichgewicht, Kinästhätik und Berührungssinn. Sie bearbeitet die Frage, ob diese drei Sinne in Bewegungslandschaften und Bewegungsbaustellen gefördert werden können. Durch das Herausarbeiten der Sinneswahrnehmungsprozesse wird klar wie wichtig diese Prozesse für unsere Entwicklung sind, und wie Bewegung dazu beiträgt die Sinneswahrnehmung zu fördern. Bewegungsförderung bedeutet letzendlich nicht nur motorische Förderung sondern trägt auch zur sozial-emotionalen Kompetez sowie zur Handlungs- und Planungskompetenz bei und bewirkt letztendlich, dass Kinder Selbstvertrauen und ein positives Selbstwertgefühl aufbauen können. Das sind die Grundvoraussetzungen, um den Herausforderungen des Lebens offen, selbstbewusst und positiv entgegentreten und meistern zu können.
description: In this thesis the author deals with the three close senses: balance, kinesthesia and touch. She works on the question whether these three senses can be promoted in movement landscapes and movement building sites. By working out the sensory perception processes, it becomes clear how important these processes are for our development, and how movement helps to promote sensory perception. In the end, movement promotion does not only mean motoric promotion, but also contributes to the social-emotional competence, to the competence to act and to plan and finally causes that children can have self-confidence and a positive self-esteem. These are the basic prerequisites for facing and mastering the challenges of life in an open, self-confident and positive manner.
Bardeen's tunneling theory applied to intraorbital and interorbital hopping integrals between dopants in silicon

description: We utilize Bardeen's tunneling theory to calculate intra- and interorbital hopping integrals between phosphorus donors in silicon using known orbital wave functions. While the two-donor problem can be solved directly, the knowledge of hoppings for various pairs of orbitals is essential for constructing multi-orbital Hubbard models for chains and arrays of donors. To assure applicability to long-range potentials, we rederive Bardeen's formula for the matrix element without assuming non-overlapping potentials. Moreover, we find a correction to the original expression allowing us to use it at short distances. We also show that accurate calculation of the lowest donor-pair eigenstates is possible based on these tunnel couplings, and we characterize the obtained states. The results are in satisfactory quantitative agreement with those obtained with the standard Hückel tight-binding method. The calculation relies solely on the wave functions in the barrier region and does not explicitly involve donor or lattice potentials, which has practical advantages. We find that neglecting the central correction potential in the standard method may lead to qualitatively incorrect results, while its explicit inclusion raises severe numerical problems, as it is contained in a tiny volume. In contrast, using wave functions obtained with this correction in the proposed method does not raise such issues. Nominally, the computational cost of the method is to calculate a double integral along the plane that separates donors. For donor separation in directions where valley interference leads to oscillatory behavior, additional averaging over the position of the integration plane is needed. Despite this, the presented approach offers a competitive computational cost as compared to the standard one. This work may be regarded as a benchmark of a promising method for calculating hopping integrals in lattice models.

description: We present data products from the 300 ks Chandra survey in the AKARI North Ecliptic Pole (NEP) deep field. This field has a unique set of 9-band infrared photometry covering 2-24 micron from the AKARI Infrared Camera, including mid-infrared (MIR) bands not covered by Spitzer. The survey is one of the deepest ever achieved at ~15 micron, and is by far the widest among those with similar depths in the MIR. This makes this field unique for the MIR-selection of AGN at z~1. We design a source detection procedure, which performs joint Maximum Likelihood PSF fits on all of our 15 mosaicked Chandra pointings covering an area of 0.34 square degree. The procedure has been highly optimized and tested by simulations. We provide a point source catalog with photometry and Bayesian-based 90 per cent confidence upper limits in the 0.5-7, 0.5-2, 2-7, 2-4, and 4-7 keV bands. The catalog contains 457 X-ray sources and the spurious fraction is estimated to be ~1.7 per cent. Sensitivity and 90 per cent confidence upper flux limits maps in all bands are provided as well. We search for optical MIR counterparts in the central 0.25 square degree, where deep Subaru Suprime-Cam multiband images exist. Among the 377 X-ray sources detected there, ~80 per cent have optical counterparts and ~60 per cent also have AKARI mid-IR counterparts. We cross-match our X-ray sources with MIR-selected AGN from Hanami et al. (2012). Around 30 per cent of all AGN that have MID-IR SEDs purely explainable by AGN activity are strong Compton-thick AGN candidates.

description: We present the concept of an acoustic rake receiver---a microphone beamformer that uses echoes to improve the noise and interference suppression. The rake idea is well-known in wireless communications; it involves constructively combining different multipath components that arrive at the receiver antennas. Unlike spread-spectrum signals used in wireless communications, speech signals are not orthogonal to their shifts. Therefore, we focus on the spatial structure, rather than temporal. Instead of explicitly estimating the channel, we create correspondences between early echoes in time and image sources in space. These multiple sources of the desired and the interfering signal offer additional spatial diversity that we can exploit in the beamformer design. We present several "intuitive" and optimal formulations of acoustic rake receivers, and show theoretically and numerically that the rake formulation of the maximum signal-to-interference-and-noise beamformer offers significant performance boosts in terms of noise and interference suppression. Beyond signal-to-noise ratio, we observe gains in terms of the \emph{perceptual evaluation of speech quality} (PESQ) metric for the speech quality. We accompany the paper by the complete simulation and processing chain written in Python. The code and the sound samples are available online at \url{http://lcav.github.io/AcousticRakeReceiver/}.

description: This work considers the scheduling problem for Urban Air Mobility (UAM) vehicles travelling between origin-destination pairs with both hard and soft trip deadlines. Each route is described by a discrete probability distribution over trip completion times (or delay) and over inter-arrival times of requests (or demand) for the route along with a fixed hard or soft deadline. Soft deadlines carry a cost that is incurred when the deadline is missed. An online, safe scheduler is developed that ensures that hard deadlines are never missed, and that average cost of missing soft deadlines is minimized. The system is modelled as a Markov Decision Process (MDP) and safe model-based learning is used to find the probabilistic distributions over route delays and demand. Monte Carlo Tree Search (MCTS) Earliest Deadline First (EDF) is used to safely explore the learned models in an online fashion and develop a near-optimal non-preemptive scheduling policy. These results are compared with Value Iteration (VI) and MCTS (Random) scheduling solutions.

Ce dernier représente l’activité maîtresse des enfants entre trois et sept ans, il leur permet d’acquérir les gains développementaux suivants: la fonction symbolique, la gestion des émotions, l’imagination, l’action en pensée, l’auto-régulation. Notre question de recherche porte sur l’évolution de situations de jeu libre et des éléments à prendre en compte lors de la mise en place de ces moments. Le travail a été conduit avec nos deux classes de stage, une classe de 1-2H et une classe de 3H. Afin de mener à bien cette recherche, l’étude de cas nous a paru la méthode la plus appropriée pour observer le phénomène du jeu libre dans toute sa complexité. Après une phase d’observation sur le jeu libre de nos élèves, nous avons mis en place un étayage collectif sur des apprentissages portant sur l’oral et le schéma narratif. Nous avons pratiqué l’observation directe, participative ou non selon les moments de la recherche. La prise de donnée s’est faite par l’utilisation des journaux de bord et des vidéos pour noter nos observations, nos questions et suivre l’évolution du jeu de nos élèves. Afin de suivre ce processus nous avons utilisé le modèle de Bodrova et Leong (2012) qui indique dans quel stade de jeu se trouvent les enfants. Nous avons alors constaté que les élèves ont évolué dans leur jeu libre, ce dernier était plus complexe, notamment en ce qui concerne la planification et le scénario. L’étayage collectif mis en place a donc été en partie efficace sur les apprentissages de nos élèves. La conclusion revient sur les apprentissages que nous avons pu faire tout au long de cette recherche ainsi que sur certaines pistes de réflexion utiles pour continuer la recherche.

description: Besides the use as cold matrix for spectroscopic studies, superfluid helium droplets have served as a cold environment for the synthesis of molecules and clusters. Since vibrational frequencies of molecules in helium droplets exhibit almost no shift compared to the free molecule values, one could assume the solvated particles move frictionless and undergo a reaction as soon as their paths cross. There have been a few unexplained observations that seemed to indicate cases of two species on one droplet not forming bonds but remaining isolated. In this work, we performed a systematic study of helium droplets doped with one rubidium and one strontium atom showing that besides a reaction to RbSr, there is a probability of finding separated Rb and Sr atoms on one droplet that only react after electronic excitation. Our results further indicate that ground-state Sr atoms can reside at the surface as well as inside the droplet.

description: We present an attempt of maximum entropy principle to determine valence quark distributions in the proton at very low resolution scale $Q_0^2$. The initial three valence quark distributions are obtained with limited dynamical information from quark model and QCD theory. Valence quark distributions from this method are compared to the lepton deep inelastic scattering data, and the widely used CT10 and MSTW08 data sets. The obtained valence quark distributions are consistent with experimental observations and the latest global fits of PDFs. Maximum entropy method is expected to be particularly useful in the case where relatively little information from QCD calculation is given.

description: Ce mémoire professionnel s’inscrit dans un contexte d’enseignement du français, plus précisément à l’usage du manuel scolaire lors de la planification d’une séquence d’enseignement. En effet, les enseignants disposent de moyens officiels approuvés par la CIIP. Le but étant de comprendre les choix pédagogiques quant à l’utilisation du manuel et autres ressources à disposition des enseignants pour mettre en oeuvre une séquence d’enseignement. La question de recherche posée est la suivante : Comment un enseignant du cycle deux utiliset- il les manuels scolaires et autres ressources lors de la planification d’une séquence didactique en français, en tenant compte des objectifs du Plan d’études ? La méthode de recherche est l’étude de cas avec une posture compréhensive. La production de données s’est faite au travers d’entretiens semi-directifs avec l’enseignant concerné et l’analyse de données est qualitative.

description: We analyze the large $N$ limit of adjoint QCD, an $SU(N)$ gauge theory with $N_f$ flavors of massless adjoint Majorana fermions, compactified on $S^3 \times S^1$. We focus on the weakly-coupled confining small-$S^3$ regime. If the fermions are given periodic boundary conditions on $S^1$, we show that there are large cancellations between bosonic and fermionic contributions to the twisted partition function. These cancellations follow a pattern previously seen in the context of misaligned supersymmetry, and lead to the absence of Hagedorn instabilities for any $S^1$ size $L$, even though the bosonic and fermionic densities of states both have Hagedorn growth. Adjoint QCD stays in the confining phase for any $L \sim N^0$, explaining how it is able to enjoy large $N$ volume independence for any $L$. The large $N$ boson-fermion cancellations take place in a setting where adjoint QCD is manifestly non-supersymmetric at any finite $N$, and are consistent with the recent conjecture that adjoint QCD has emergent fermionic symmetries in the large $N$ limit.

description: We generalize the scattering equations to include both massless and massive particles. We construct an expression for the tree-level n-point amplitude with n-2 gluons or gravitons and a pair of massive scalars in arbitrary spacetime dimension as a sum over the (n-3)! solutions of the scattering equations, a la Cachazo, He, and Yuan. We derive the BCJ relations obeyed by these massive amplitudes.

description: À travers ce mémoire, nous avons construit et utilisé un portfolio orientant dans une classe vaudoise de 5-6ème année primaire. Cet outil, issu de l’approche orientante, vise à développer l’identité et le chemin vocationnel des élèves. En mettant en place le portfolio, nous avons cherché à savoir s’il pouvait influencer la motivation intrinsèque des élèves vis-à-vis de l’école. Pour l’étudier, nous avons adopté une posture compréhensive et une démarche d’enquête sur le terrain. Les données ont été produites grâce aux portfolios eux-mêmes et à des entretiens compréhensifs avec quelques élèves. Les résultats nous montrent que la motivation intrinsèque a été positivement influencée par ce dispositif chez la majorité des élèves. Ils ont principalement développé du plaisir, mais aussi de l’intérêt vis-à-vis de l’école. Dans une moindre mesure, une certaine curiosité est également apparue dans leurs réponses.

description: Training recurrent neural networks is predominantly achieved via backpropagation through time (BPTT). However, this algorithm is not an optimal solution from both a biological and computational perspective. A more efficient and biologically plausible alternative for BPTT is e-prop. We investigate the applicability of e-prop to long short-term memorys (LSTMs), for both supervised and reinforcement learning (RL) tasks. We show that e-prop is a suitable optimization algorithm for LSTMs by comparing it to BPTT on two benchmarks for supervised learning. This proves that e-prop can achieve learning even for problems with long sequences of several hundred timesteps. We introduce extensions that improve the performance of e-prop, which can partially be applied to other network architectures. With the help of these extensions we show that, under certain conditions, e-prop can outperform BPTT for one of the two benchmarks for supervised learning. Finally, we deliver a proof of concept for the integration of e-prop to RL in the domain of deep recurrent Q-learning.
Electric bias control on impurity effects in bigraphene

description: Formation of localized impurity levels within the band gap in bigraphene under applied electric field is considered and the conditions for their collectivization at finite impurity concentration are established. It is shown that a qualitative restructuring of quasiparticle spectrum within the initial band gap and then specific metal-insulator phase transitions are possible for such disordered system and can be effectively controlled by variation of the electric field bias at given impurity perturbation potential and concentration. Since these effects can be expected at low impurity concentrations but at not too low temperatures, they can be promising for practical applications in nanoelectronics devices.

description: Sur la base des recherches menées sur la méditation de pleine conscience, ce Travail étudie le cas de quatre élèves de 7ème année Harmos et quatre élèves de 6ème année Harmos, ayant vécu cette expérience. Les séances de méditation de pleine conscience inspirées de l’ouvrage « Un prof heureux peut changer le monde » (Nhat Hanh et Weare, 2018) ont été menées en classe et réalisées en tant que rituels, d’environ cinq minutes, dans le but de savoir comment les élèves vivaient celles-ci et où est-ce qu’ils dirigeaient leur attention durant ces moments. Les exercices que nous avons pratiqués portaient sur la pleine conscience de la respiration, notamment sur son mouvement. Pour obtenir des réponses, nous avons d’abord relevé la direction de leur attention à l’aide d’entretien d’auto-confrontation possibles grâce à la présence d’une caméra en classe, et par la suite, nous avons changé d’outil de recueil de donnée et avons réalisé des entretiens d’explicitation. Afin de traiter nos données, nous avons formé plusieurs catégories pour l’attention et pour le vécu puis nous les avons croisées avec les éléments de notre cadrage théorique. Ces derniers sont le moment présent, l’inconfort, le non-jugement et l’attention endogène ou également dite volontaire. Notre recherche montre que, durant les séances ritualisées de pleine conscience, les élèves portent leur attention sur plusieurs éléments qui les entourent au moment présent et non pas uniquement sur leur respiration. Mais est-ce un problème ? De plus, quelle est l’influence du vécu des élèves durant ces séances sur la poursuite ou l’abandon de la pratique ? Enfin, autrui est-il une source d’attention exogène et ferait ainsi « sortir » les élèves du travail de la méditation de pleine conscience ?

description: We study totally disconnected locally compact second countable (t.d.l.c.s.c.) groups that contain a compact open subgroup with finite rank. We show such groups that additionally admit a pro-$π$ compact open subgroup for some finite set of primes $π$ are virtually an extension of a finite direct product of topologically simple groups by an elementary group. This result, in particular, applies to l.c.s.c. $p$-adic Lie groups. We go on to prove a decomposition result for all t.d.l.c.s.c. groups containing a compact open subgroup with finite rank. In the course of proving these theorems, we demonstrate independently interesting structure results for t.d.l.c.s.c. groups with a compact open pro-nilpotent subgroup and for topologically simple l.c.s.c. $p$-adic Lie groups.

description: Ce mémoire porte sur les modalités de conduite d’un projet théâtre avec des enfants du premier cycle. Le projet est une approche pédagogique dans laquelle l’élève est acteur·trice dans la construction des savoirs. Il est également source de motivation et de plaisir pour les élèves et les enseignant·e·s. Le théâtre peut faire l’objet d’un projet. La pratique théâtrale est source de nombreux apprentissages pour les élèves du cycle 1. Il permet d’aborder la corporéité, l’oralité, le genre théâtral comme texte et l’interculturel, les capacités transversales, la mémorisation, le développement des facultés artistiques, la décentration et la compréhension du monde proche. Cette pratique est toutefois très peu présente dans ces degrés. L’exercice du théâtre est plutôt pensé pour des classes du cycle 2, du secondaire I, du secondaire II et du français langue étrangère. Il est parfois également utilisé comme outil pour aider les élèves à besoins particuliers. Quelles sont les raisons qui peuvent inciter les enseignant·e·s du premier cycle à mener des projets théâtres en classe ; quels sont les ressources et les moyens qui peuvent les amener à utiliser cet outil d’enseignement-apprentissage ? Pour répondre à cette question, nous avons mené des entretiens avec des enseignantes du cycle 1 et avec des professionnels du monde du théâtre. L’analyse des entretiens montre que les principaux obstacles sont : le temps, le budget, le manque de formation « théâtrale » et le manque de motivation des enseignant·e·s et les principales recommandations reposent sur le fait de se former, d’avoir une vision globale du projet, de faire simple en ce qui concerne les décors, les accessoires, les costumes et le maquillage. L’envie et la motivation demeurent les ingrédients essentiels.
