VAFB-1988-07: RE: Results of Archaeological Monitoring of Geotechnical Exploration at the Proposed Space Launch Complex 7 (SLC 7) Project Area, Vandenberg Air Force Base
Creators: name: Marmor, Jason
Year: 1988

description: This document is a monitoring report describing archaeological observation of geotechnical core drilling at the proposed project site of Space Launch Complex 7 (SLC-7). Monitoring of soil core extraction at selected locations was recommended as a result of an earlier intensive cultural resources survey of the SLC 7 project area. During the course of the project a number of lithic artifacts including possibly utilized flakes were observed on the surface in the vicinity of the terrace top just west of as well as along the western edge of the unnamed drainage which forms the eastern border of the SLC 7 project site. These appear to be associated with the other isolated artifacts discovered during the 1987 intensive survey and may represent evidence of aboriginal activity contemporaneous with or possibly more recent than that associated with CA-SBA-1117.

description: Nonlinear extensions to the active subspaces method have brought remarkable results for dimension reduction in the parameter space and response surface design. We further develop a kernel-based nonlinear method. In particular we introduce it in a broader mathematical framework that contemplates also the reduction in parameter space of multivariate objective functions. The implementation is thoroughly discussed and tested on more challenging benchmarks than the ones already present in the literature, for which dimension reduction with active subspaces produces already good results. Finally, we show a whole pipeline for the design of response surfaces with the new methodology in the context of a parametric CFD application solved with the Discontinuous Galerkin method.

description: Cette étude vise à déterminer, au sein d’un établissement secondaire vaudois, si on constate des changements dans les épreuves certificatives de 9VSG entre 1991 et 2012. Notre hypothèse est qu’une étude rétrospective des épreuves permet de relever certains courants pédagogiques et didactiques, ainsi que des ruptures qui relèveraient des changements dans les pratiques d’enseignement. Après une présentation du contexte historique, nous analysons les épreuves par leur contexte et par leurcontenu. Des apports théoriques, l’analyse des manuels d’enseignement, les consignes du département et l’interview du chef de file de français de l’établissement soutiennent nos propos. L’analyse se divise en deux temps: un travail longitudinal qui étudie les données des examens sur vingt-deux ans à la lumière des évolutions au sein du système scolaire cantonal, puis, une focalisation sur cinq examens particuliers. Deux éléments principaux ressortent. Premièrement, jusqu’en 2002, les épreuves testent des connaissances prescrites par le plan d’études (alignement curriculaire) et travaillées en classe (alignement pédagogique) dans de courts exercices, alors que dès 2003, les objectifs à atteindre sont formulés sous forme de compétences àmaîtriser. Deuxièmement, le niveau taxonomique des tâches que les élèves doivent réalisera évolué: d’exercices d’application, voire de restitution jusqu’en 2002, on passe, à partir de l’épreuve de 2003, à une seule tâche complexe. Les changements majeurs, visibles depuis 2003, s’expliquent par la mise en place de la réforme EVM en 1997, suivie en 2001, par le PEV, ainsi que par les directives du département qui ont été édictées. Pour conclure, cette étude reste ouverte aux futures recherches. Avec le PER (plan d’études romand) dès la rentrée scolaire 2012-2013 et l’entrée en vigueur de la nouvelle loi sur l’enseignement obligatoire (LEO) l’année suivante, nous pouvons déduire qu’il y a de fortes chances pour que dans le futur cela ait un impact sur la forme et/ou le contenu des futurs certificats de 9ème année scolaire ou plutôt, de 11ème année (Harmos).

Endovascular procedure

description: Notwithstanding technological improvements in endovascular devices treatment of steno-obstructive lesions of the superficial femoral artery (SFA) remains a challenge for today’s vascular surgeon. Current opinion dictates that the diabetic population may have worse outcome after revascularization of the lower extremities. Herein we examine the effects of endovascular treatment on steno-obstructive lesions of the SFA in diabetic and non-diabetic patients. Methods – A retrospective analysis was carried out on 110 patients who had undergone endovascular treatment of the SFA from 2010 to 2017 comparing outcomes in diabetic (DM) vs non-diabetic patients (nDM). Results – 56 (50.9%) of the patients were diabetic and 54 were non-diabetic (49.1%). 52.7% (62.7% DM vs 35.2% nDM, p = 0.0003) were patients with critical limb ischemia. SFA occlusion was present in 65.5% (60.7% DM vs 70.4% nDM, p = 0.29) of all patients. All had undergone PTA of the SFA and 40.9% had received adjunctive stenting (44.6% DM vs 37.0% nDM, p = 0.41). A multilevel treatment was executed in 39.1% (51.8% DM vs 25.9% nDM) of the cases whereas an infra-popliteal procedure was associated in 27.3% (37.5% DM vs 16.7% nDM). In both groups the presence of diabetes was significantly associated (p = 0.005 e p = 0.014, respectively). Reintervention rate was 22.7%; 13 in the diabetic group (23.2%) and 12 in the non-diabetic group (22.2%). Of those who had had reintervention (p = 0.77); 9 patients (8.2%) had undergone an open surgical operation, 6 of whom had diabetes (p = 0.32). 5 patients (4.5%) had had major amputation, 4 of whom were diabetic (p = 0.20). Curves assessing freedom from target lesion restenosis were substantially overlapping between the two groups. Conclusion - No statistical associations between diabetes and reintervention or amputation rates were found. Indication to treat the SFA were not influenced by the presence of diabetes but further investigation is required to verify our hypothesis.

description: We report on the characterization of the Kepler-101 planetary system, thanks to a combined DE-MCMC analysis of Kepler data and forty radial velocities obtained with the HARPS-N spectrograph. This system was previously validated by Rowe et al. (2014) and is composed of a hot super-Neptune, Kepler-101b, and an Earth-sized planet, Kepler-101c. These two planets orbit the slightly evolved and metal-rich G-type star in 3.49 and 6.03 days, respectively. With mass $M_{\rm p}=51.1_{-4.7}^{+5.1}~M_{\oplus}$, radius $R_{\rm p}=5.77_{-0.79}^{+0.85}~R_{\oplus}$, and density $ρ_{\rm p}=1.45_{-0.48}^{+0.83} \rm g\;cm^{-3}$, Kepler-101b is the first fully-characterized super-Neptune, and its density suggests that heavy elements make up a significant fraction of its interior; more than $60\%$ of its total mass. Kepler-101c has a radius of $1.25_{-0.17}^{+0.19}~R_{\oplus}$, which implies the absence of any H/He envelope, but its mass could not be determined due to the relative faintness of the parent star for highly precise radial-velocity measurements ($K_{\rm p}=13.8$) and the limited number of radial velocities. The $1~σ$ upper limit, $M_{\rm p} < 3.8~M_{\oplus}$, excludes a pure iron composition with a $68.3\%$ probability. The architecture of the Kepler-101 planetary system - containing a close-in giant planet and an outer Earth-sized planet with a period ratio slightly larger than the 3:2 resonance - is certainly of interest for planet formation and evolution scenarios. This system does not follow the trend, seen by Ciardi et al. (2013), that in the majority of Kepler systems of planet pairs with at least one Neptune-size or larger planet, the larger planet has the longer period.

description: We consider smooth nonparametric estimation of the incubation time distribution of COVID-19, in connection with the investigation of researchers from the National Institute for Public Health and the Environment (Dutch: RIVM) of 88 travelers from Wuhan: Backer et al (2020). The advantages of the smooth nonparametric approach w.r.t. the parametric approach, using three parametric distributions (Weibull, log-normal and gamma) in Backer et al (2020) is discussed. It is shown that the typical rate of convergence of the smooth estimate of the density is $n^{2/7}$ in a continuous version of the model, where $n$ is the sample size. The (non-smoothed) nonparametric maximum likelihood estimator (MLE) itself is computed by the iterative convex minorant algorithm (Groeneboom and Jongbloed (2014)). All computations are available as {\tt R} scripts in Groeneboom (2020).

description: The recent development of genetically encoded calcium indicators enables monitoring in vivo the activity of neuronal populations. Most analysis of these calcium transients relies on linear regression analysis based on the sensory stimulus applied or the behavior observed. To estimate the basic properties of the functional neural circuitry, we propose a network-based approach based on calcium imaging recorded at single cell resolution. Differently from previous analysis based on cross-correlation, we used Granger-causality estimates to infer activity propagation between the activities of different neurons. The resulting functional networks were then modeled as directed graphs and characterized in terms of connectivity and node centralities. We applied our approach to calcium transients recorded at low frequency (4 Hz) in ventral neurons of the zebrafish spinal cord at the embryonic stage when spontaneous coiling of the tail occurs. Our analysis on population calcium imaging data revealed a strong ipsilateral connectivity and a characteristic hierarchical organization of the network hubs that supported established propagation of activity from rostral to caudal spinal cord. Our method could be used for detecting functional defects in neuronal circuitry during development and pathological conditions.

description: We demonstrate current-induced bipolar switching in in-plane magnetized spin-valve devices that incorporate a perpendicularly magnetized spin polarizing layer. Further, hysteretic transitions into a state with intermediate resistance occur at high currents, again for both current polarities. These transitions are shown to be consistent with a macrospin model that considers a spin-polarized current that is tilted with respect to the free layer plane, due to the presence of spin-transfer torque from the polarizing layer. These unique switching characteristics, which have their origin in the noncollinear layer magnetizations, are of interest for magnetic random access memory and spin-torque oscillator devices.

Local Ihara's lemma and applications

description: Persistence of non-degeneracy is a phenomenon which appears in the theory of $\overline{\mathbb Q}_l$-representations of the linear group: every irreducible submodule of the restriction to the mirabolic sub-representation of a non-degenerate irreducible representation is non-degenerate. This is not true anymore in general, if we look at the modulo $l$ reduction of some stable lattice. As in the Clozel-Harris-Taylor generalization of global Ihara's lemma, we show that this property, called non-degeneracy persistence and related to the notion of essentially absolutely irreducible and generic representations in the work of Emerton-Helm, remains true for lattices given by the cohomology of Lubin-Tate spaces. As an global application, we give a new construction of automorphic congruences in the Ribet spirit.

description: This paper describes a helical deflector to perform circular sweeps of keV electrons by means of radio frequency fields in a frequency range 500-1000 MHz. By converting the time dependence of incident electrons to a hit position dependence on a circle, this device can potentially achieve extremely precise timing. The system can be adjusted to the velocity of the electrons to exclude the reduction of deflection sensitivity due to finite transit time effects. The deflection electrodes form a resonant circuit, with quality factor Q in excess of 100, and at resonance the sensitivity of the deflection system is around 1~mm per V of applied RF input.

description: We study the stochastic total variation flow (STVF) equation with linear multiplicative noise. By considering a limit of a sequence of regularized stochastic gradient flows with respect to a regularization parameter $\varepsilon$ we obtain the existence of a unique variational solution of the STVF equation which satisfies a stochastic variational inequality. We propose an energy preserving fully discrete finite element approximation for the regularized gradient flow equation and show that the numerical solution converges to the solution of the unregularized STVF equation. We perform numerical experiments to demonstrate the practicability of the proposed numerical approximation. This paper contains a mistake: in the proof of Lemma 4.4 the last inequality is not valid. Meanwhile, this mistake has been fixed in [6] for a slightly modified numerical approximation in spatial dimension $d=1$. For $d\geq 1$ the validity of the estimate in Lemma 4.4 is still open but the convergence of the numerical approximation can be shown by a different approach, see [5].
VAFB-1987-04: Cultural Resources Survey of Proposed Small Intercontinental Ballistic Missile and Peacekeeper Rail Garrison Test Areas, San Antonio Terrace, Vandenberg Air Force Base, California
Creators: name: Zalud, Arianna
Year: 1987

description: A cultural resources survey and archival study of areas on VAFB proposed for expansion of testing facilities for Small Intercontinental Ballistic Missile and the Peacekeeper Rail Garrison programs was conducted. Eighteen archaeological sites were identified during the survey of approximately 1100 acres. This brings to 39 the total number of sites known to exist in the three survey areas. Most of the sites represent camps or projectile-point preparation locations used by prehistoric hunters in the dune environment of San Antonio Terrace. Of the 39 sites, 17 are evaluated as eligible for the NRHP. It is recommended that a National Register district be formed to more efficiently manage cultural resources which could be affected by the proposed undertaking. Test facility planning and design should take into account the locations of these 17 sites.

description: As an intrinsically unbiased method, the quantum Monte Carlo (QMC) method is of unique importance in simulating interacting quantum systems. Although the QMC method often suffers from the notorious sign problem, the sign problem of quantum models may be mitigated by finding better choices of the simulation scheme. However, a general framework for identifying optimal QMC schemes has been lacking. Here, we propose a general framework using automatic differentiation to automatically search for the best QMC scheme within a given ansatz of the Hubbard-Stratonovich transformation, which we call "automatic differentiable sign optimization" (ADSO). We apply the ADSO framework to the honeycomb lattice Hubbard model with Rashba spin-orbit coupling and demonstrate that ADSO is remarkably effective in mitigating and even solving its sign problem. Specifically, ADSO finds a sign-free point in the model which was previously thought to be sign-problematic. For the sign-free model discovered by ADSO, its ground state is shown by sign-free QMC simulations to possess spiral magnetic ordering; we also obtained the critical exponents characterizing the magnetic quantum phase transition.

description: Cell-cell communication plays a pivotal role in the coordination and function of biological systems. Three-dimensional (3D) cellular constructs provide venues to explore cellular communication for tissue development and drug discovery, as their 3D architecture mimics native in vivo microenvironments. Cellular electrophysiology (EP) is a prevalent signaling paradigm for studying electroactive cells. Currently, electrophysiological studies do not provide direct, multisite, simultaneous investigation of tissues in 3D. In this thesis, a controlled 3D assembly of biosensors was achieved via self-rolling. The 3D self-rolled biosensor arrays (3D-SR-BAs) were fabricated with customized geometries, designed to tightly interface 3D cellular constructs of varied sizes. The geometric arrangement of the sensors on the array provided a high spatial resolution in such a way that the electrical signal from individual cells can be recorded. 3D-SR-BA platform was shown to accommodate different sensor types: active field-effect transistors and passive microelectrodes. 3D-SR-BAs were interfaced with a few models of 3D-cultured constructs: human cardiac spheroids, human cardiac tissues, and rat cortical spheroids. The arrays provided continuous and stable multiplexed recordings of extracellular potentials with high sensitivity and spatiotemporal resolution, supported with simultaneous calcium imaging. The approach established in this work enabled EP investigation and monitoring of the complex signal transduction in 3D cardiac constructs. Additionally, the platform was sensitive enough to detect single-neuron and network activity in cortical spheroids. 3D-SR-BAs developed in this thesis provide a novel and versatile technology toward an organ-on-an-electronic-chip (organ-on-e-chip) platform for studying EP of 3D constructs in both healthy and diseased states. This platform can be further used in long-term EP studies to investigate and advance engineered tissue maturation, as well as develop and test therapeutics for personalized medicine.

description: En 2006, l’OMS relate qu’au moins deux tiers des habitants de plus de 15 ans de l’Union Européenne pratique moins de 30 minutes d’activité physique d’intensité modérée par jour, tout comme 60 % de la population mondiale (Warburton et al., 2007). Ce constat nous a alarmé en tant qu'enseignants d'éducation physique. D'ailleurs, nous observons que nos élèves ont des habiletés motrices parfois très faibles, qui vont souvent de pair avec un surpoids ou de l'obésité. Notre premier objectif a donc été d'établir le niveau d'activité physique quotidienne de nos élèves par rapport aux références médicales : entre 10'000 et 13'000 pas par jour (Janssen I,2007), qui a été calculée à l'aide de podomètres prêtés aux élèves. Malgré des recommandations médicales et sociales, communément répandues, les enfants ne bougent pas assez. Notre hypothèse est donc qu'ils ne perçoivent pas adéquatement leur niveau d'activité physique. En effet, si un enfant pense bouger beaucoup, il ne changera pas son comportement face à ces recommandations. Pour vérifier cette hypothèse, les élèves de nos classes (cinq classes de 5 à 8e) ont rempli un questionnaire sur la perception qu'ils avaient de leur activité physique et sportive, ainsi que de leur condition physique (force, endurance, détente, agilité, souplesse, vitesse). Les tests de condition physique sont ceux qui se trouvent dans le carnet d'éducation physique vaudois. En comparant ces différentes données, nous avons constaté que nos élèves ont une bonne activité physique (la moyen ne se trouvant à 12288 pas quotidiens) ainsi qu'une bonne perception de celle-ci. Concernant les facteurs de condition physique, ce travail de recherche a révélé que ces tests étaient peut-être à modifier afin qu'ils soient plus complets et ainsi permettent une analyse plus exacte en fonction de l'âge et du sexe. D'autre part, cela permettrait aux élèves de se percevoir d'autant mieux en condition physique. En outre, les élèves les plus actifs n'ont pas été les plus performants en condition physique. Nous arrivons à la conclusion qu'il serait préférable de suivre leur évolution à travers leur scolarité au lieu de comparer différentes classes.

Son objectif principal est de déterminer si l’apport du test de GACON peut avoir un impact positif sur la motivation des élèves envers l’endurance. Par ailleurs, elle permet également d’obtenir, sur le plan motivationnelle, la représentation des élèves, du test de COOPER. Cette étude fait suite à un prétest, réalisé avec des maîtres d’éducation physique, qui préconise l’emploi d’un second test d’endurance afin de motiver les élèves à travailler leur endurance. Méthode : Cette étude a été réalisée avec une classe hétérogène. Cette dernière se compose de 22 élèves (13 garçons, 9 filles), âgés de 11 à 12 ans. Une élève blessée n’a pas pu prendre part à l’étude. Les élèves ont réalisé dans un premier temps le test de COOPER puis, deux semaines plus tard, le test de GACON. Au préalable, les élèves ont été entrainés à l’endurance mais de manière non spécifique aux tests expérimentés. Résultats : Au terme de l’expérience et après avoir analysé les résultats, il s’est avéré que les élèves sont plus motivés par le test de GACON, qu’ils s’investissent plus et qu’ils ont plus de plaisir qu’au test de COOPER. Il a également été observé que les élèves courent plus longtemps au test de COOPER. La variation suscite donc auprès des élèves un certain engouement positif pour le travail de l’endurance. Conclusion : En conclusion, l’hypothèse que la variation, par l’apport d’un test d’endurancesupplémentaire, pouvait motiver les élèves a été confirmée. L’apport d’un second test pour travailler et évaluer l’endurance serait bénéfique dans le cadre du programme scolaire.

description: We construct a map from $d|1$-dimensional Euclidean field theories to complexified K-theory when $d=1$ and complex analytic elliptic cohomology when $d=2$. This provides further evidence for the Stolz--Teichner program, while also identifying candidate geometric models for Chern characters within their framework. The construction arises as a higher-dimensional and parameterized generalization of Fei Han's realization of the Chern character in K-theory as dimensional reduction for $1|1$-dimensional Euclidean field theories. In the elliptic case, the main new feature is a subtle interplay between the geometry of the super moduli space of $2|1$-dimensional tori and the derived geometry of complex analytic elliptic cohomology. As a corollary, we obtain an entirely geometric proof that partition functions of $\mathcal{N}=(0,1)$ supersymmetric quantum field theories are weak modular forms, following a suggestion of Stolz and Teichner.

description: Using a recent breakthrough of Smith, we improve the results of Fouvry and Klüners on the solubility of the negative Pell equation. Let $\mathcal{D}$ denote the set of fundamental discriminants having no prime factors congruent to $3$ modulo $4$. Stevenhagen conjectured that the density of $D$ in $\mathcal{D}$ such that the negative Pell equation $x^2-Dy^2=-1$ is solvable with $x,y\in\mathbb{Z}$ is $58.1\%$, to the nearest tenth of a percent. By studying the distribution of the $8$-rank of narrow class groups $\mathrm{CL}^+(D)$ of $\mathbb{Q}(\sqrt{D})$, we prove that the infimum of this density is at least $53.8\%$.

description: La société d’aujourd’hui est de plus en plus compétitive et là, où chacun-e cherche à performer ses compétences professionnelles et personnelles, le coaching est sur le devant de la scène que ce soit dans le milieu sportif ou le milieu entrepreneurial en offrant une possible réponse. Le coaching offre des outils pour faire prendre conscience des forces et des faiblesses de celui ou celle qui s’engage dans une démarche, lui permettant de rester motivé-e et de persévérer dans son projet pour atteindre l’objectif fixé. Il est donc envisageable que le coaching soit un outil motivationnel transposable en milieu scolaire permettant d’engager les élèves à performer leurs compétences. Dans ma pratique de tous les jours, j’ai constaté que les élèves ne s’approprient pas de la même manière les tâches scolaires et n’ont pas le même niveau motivationnel. Ainsi, la motivation n’est pas spontanée chez les élèves, fragile et instable, elle varie par rapport à des critères de type intrinsèque ou extrinsèque comme : le degré d’investissement, le choix du coach, la réflexion initiale, le plaisir, le mode d’enseignement, la confidentialité, le choix de l’activité l’horaire ou les encouragements. L’environnement, la tâche mais aussi le vécu de l’élève influent fortement sur le niveau, le maintien et la progression de cette motivation, cela m’amène à penser que, s’engager de « son plein gré » dans une démarche de coaching offre une meilleure capacité d’autorégulation de la motivation chez un public adolescent.

title: Sea surface wind and wave parameter estimation from X-band marine radar images with rain detection and mitigation
Creators: name: Chen, Xinwei
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: In this research, the application of X-band marine radar backscatter images for sea surface wind and wave parameter estimation with rain detection and mitigation is investigated. In the presence of rain, the rain echoes in the radar image blur the wave signatures and negatively affect estimation accuracy. Hence, in order to improve estimation accuracy, it is meaningful to detect the presence of those rain echoes and mitigate their influence on estimation results. Since rain alters radar backscatter intensity distribution, features are extracted from the normalized histogram of each radar image. Then, a support vector machine (SVM)-based rain detection model is proposed to classify radar images obtained between rainless and rainy conditions. The classification accuracy shows significant improvement compared to the existing threshold-based method. By further observing images obtained under rainy conditions, it is found that many of them are only partially contaminated by rain echoes. Therefore, in order to segment between rain-contaminated regions and those that are less or unaffected by rain, two types of methods are developed based on unsupervised learning techniques and convolutional neural network (CNN), respectively. Specifically, for the unsupervised learning-based method, texture features are first extracted from each pixel and then trained using a self organizing map (SOM)-based clustering model, which is able to conduct pixel-based identification of rain-contaminated regions. As for the CNN-based method, a SegNet-based semantic segmentation CNN is �rst designed and then trained using images with manually annotated labels. Both shipborne and shore-based marine radar data are used to train and validate the proposed methods and high classification accuracies of around 90% are obtained. Due to the similarities between how haze affects terrestrial images and how rain affects marine radar images, a type of CNN for image dehazing purposes, i.e., DehazeNet, is applied to rain-contaminated regions in radar images for correcting the in uence of rain, which reduces the estimation error of wind direction significantly. Besides, after extracting histogram and texture features from rain-corrected radar images, a support vector regression (SVR)-based model, which achieves high estimation accuracy, is trained for wind speed estimation. Finally, a convolutional gated recurrent unit (CGRU) network is designed and trained for significant wave height (SWH) estimation. As an end-to-end system, the proposed network is able to generate estimation results directly from radar image sequences by extracting multi-scale spatial and temporal features in radar image sequences automatically. Compared to the classic signal-to-noise (SNR)-based method, the CGRU-based model shows significant improvement in both estimation accuracy (under both rainless and rainy conditions) and computational efficiency.

description: L'enseignant de français au niveau secondaire I jouit d'une grande liberté dans le choix des oeuvres qu'il souhaite aborder en classe. Les programmes restent relativement vagues et ne prescrivent pas de corpus qui devrait obligatoirement être étudié. Or, dans notre pratique, nous avons pu parfois observer une certaine réticence de nos collègues face à la littérature extrêmement contemporaine et une tendance à choisir des oeuvres plus anciennes, souvent assimilables à ce qu'on nomme grands classiques. Mais qu'en est-il dans la réalité ? A notre connaissance, aucune étude à ce jour ne traite de la relation des enseignants à la littérature extrêmement contemporaine, c'est pourquoi nous avons formulé la question centrale suivante : Quelle place les enseignants du niveau secondaire I accordent-ils à la littérature postérieure à1980 dans l’enseignement du français de la 7ème à la 9ème année ? Pour traiter de ce sujet, nous nous sommes d'abord penchées sur quelques notions théoriques particulièrement importantes. Nous avons proposé des pistes définitionnelles destermes littérature, canon, classique et littérature extrêmement contemporaine. Ensuite, nous avons réalisé une enquête auprès de nos collègues. Les questions posées devaient nous permettre de découvrir quelle place ils accordent à la littérature extrêmement contemporaine dans leurs pratiques privées et professionnelles et quels critères ils évoquent lorsqu'ils affirment ne pas souhaiter étudier une oeuvre en classe. Nos résultats ont montré que les enseignants du degré secondaire I lisent volontiers pour leur plaisir des oeuvres extrêmement contemporaines et qu'ils les étudient souvent en classe. La comparaison entre les deux collèges dans lesquels nous effectuons nos stages nous a permis de relever des pratiques relativement différentes que nous avons expliquées comme relevant à la fois de la culture d'établissement et de la volonté des professionnels de s'adapter aux capacités de leurs élèves. Enfin, nous avons pu constater que les raisons pour lesquelles un enseignant rejette une oeuvre ne sont pas exactement les mêmes lorsqu'il s'agit de littérature antérieure ou postérieure à 1980. En conclusion, nous avons pu ouvrir notre réflexion à la question du rôle que joue l'école dans le maintien des inégalités sociales.

description: We introduce a new geometric-analytic functional that we analyse in the context of free discontinuity problems. Its main feature is that the geometric term (the length of the jump set) appears with negative sign. This is motivated by searching quantitative inequalities for best constants of Sobolev-Poincaré inequalities with trace terms in $\mathbb{R}^n$ which correspond to fundamental eigenvalues associated to semilinear problems for the Laplace operator with Robin boundary conditions. Our method is based on the study of this new, degenerate, functional which involves an obstacle problem in interaction with the jump set. Ultimately, this becomes a mixed free discontinuity/free boundary problem occuring above/at the level of the obstacle, respectively.

description: We establish probabilistic small data global well-posedness of the energy-critical Maxwell-Klein-Gordon equation relative to the Coulomb gauge for scaling super-critical random initial data. The proof relies on an induction on frequency procedure and a modified linear-nonlinear decomposition furnished by a delicate "probabilistic" parametrix construction. This is the first global existence result for a geometric wave equation for random initial data at scaling super-critical regularity.
