description: Ce travail de mémoire expose le cheminement parcouru par les auteurs et leurs justifications pour proposer une nouvelle séquence de droit aux élèves autour de la thématique de la responsabilité environnementale. En se basant notamment sur les recommandations du guide « Éducation à la durabilité et PER », cette séquence a pour ambition d’amener les élèves à se questionner, à réaliser des démarches d’enquête et à favoriser leur créativité pour pouvoir développer des savoirs disciplinaires et transversaux sur le thème de la durabilité, avec en toile de fond l’utilisation d’approches multidimensionnelles à commencer par le modèle du « donut ». Dans la mise en place de cette séquence traitant de questions socialement vives, les auteurs sont partis de la problématique suivante : quelle influence une modalité d’enseignement en « indoor » et en « outdoor » a-t-elle sur la motivation et les apprentissages des élèves ? La méthodologie mise en place dans le cadre du déroulement de cette séquence en classe durant l’année scolaire 2021-2022 a permis aux auteurs de proposer une analyse tant sur la motivation que sur les apprentissages des élèves ainsi qu’une analyse métacognitive sur le travail réalisé. Les auteurs ont ainsi pu notamment constater que de nombreux liens avec les cadres théoriques proposés peuvent être faits dans le cadre de cette séquence, mais aussi que la complexité d’une approche multidimensionnelle peut avoir un impact non négligeable sur la motivation et les apprentissages des élèves. En effet, cette approche contribue à permettre aux élèves de développer des différents regards et de tendre vers un esprit critique. Forts de ces constats, les auteurs proposent des pistes d’actions afin d’améliorer encore à l’avenir le déroulement de cette séquence, spécialement en mélangeant davantage les modalités d’enseignement en « indoor » et en « outdoor » et en ouvrant une possibilité visant à favoriser davantage d’interdisciplinarité.

description: We investigate periodic optomechanical arrays as reconfigurable platforms for engineering the coupling between multiple mechanical and electromagnetic modes and for exploring many-body phonon dynamics. Exploiting structural resonances in the coupling between light fields and collective motional modes of the array, we show that tunable effective long-range interactions between mechanical modes can be achieved. This paves the way towards the implementation of controlled phononic walks and heat transfer on densely-connected graphs as well as the coherent transfer of excitations between distant elements of optomechanical arrays.

description: We investigate large-scale structure formation of collisionless dark matter in the phase space description based on the Vlasov equation whose nonlinearity is induced solely by gravitational interaction according to the Poisson equation. Determining the time-evolution of density and peculiar velocity demands solving the full Vlasov hierarchy for the moments of the phase space distribution function. In the presence of long-range interaction no consistent truncation of the hierarchy is known apart from the pressure- less fluid (dust) model which is incapable of describing virialization due to the occurrence of shell-crossing singularities and the inability to generate vorticity and higher cumulants like velocity dispersion. Our goal is to find a simple ansatz for the phase space distribution function that approximates the full Vlasov distribution function without pathologies in a controlled way and therefore can serve as theoretical N-body double and as a replacement for the dust model. We argue that the coarse-grained Wigner probability distribution obtained from a wave function fulfilling the Schrödinger-Poisson equation (SPE) is the sought-after function. We show that its evolution equation approximates the Vlasov equation and therefore also the dust equations before shell-crossing, but cures the shell-crossing singularities and is able to describe regions of multi-streaming and virialization. This feature was already employed in simulations by Widrow & Kaiser (1993). The coarse-grained Wigner ansatz allows to calculate all higher moments from density and velocity analytically, thereby incorporating nonzero higher cumulants in a self-consistent manner. On this basis we are able to show that the Schrödinger method (ScM) automatically closes the corresponding hierarchy such that it suffices to solve the SPE in order to directly determine density and velocity and all higher cumulants.

description: Considering any Hamiltonian, any initial state, and measurements with a small number of possible outcomes compared to the dimension, we show that most measurements are already equilibrated. To investigate non-trivial equilibration we therefore consider a restricted set of measurements. When the initial state is spread over many energy levels, and we consider the set of observables for which this state is an eigenstate, most observables are initially out of equilibrium yet equilibrate rapidly. Moreover, all two-outcome measurements, where one of the projectors is of low rank, equilibrate rapidly.

description: Fermi LAT has detected gamma ray emissions from the core of Cen A. More recently, a new component in the gamma ray spectrum from the core has been reported in the energy range of 4 GeV to tens of GeV. We show that the new component and the HESS detected spectrum of gamma rays from the core at higher energy have possibly a common origin in photo-disintegration of heavy nuclei. Assuming the cosmic rays are mostly Fe nuclei inside the core and their spectrum has a low energy cut-off at 52 TeV in the wind frame moving with a Doppler factor 0.25 with respect to the observer on earth, the cosmic ray luminosity required to explain the observed gamma ray flux above 1 GeV is found to be $1.5\times 10^{43}$ erg/sec.

description: We study networks of non-locally coupled electronic oscillators that can be described approximately by a Kuramoto-like model. The experimental networks show long complex transients from random initial conditions on the route to network synchronization. The transients display complex behaviors, including resurgence of chimera states, which are network dynamics where order and disorder coexists. The spatial domain of the chimera state moves around the network and alternates with desynchronized dynamics. The fast timescale of our oscillators (on the order of $100\;\mathrm{ns}$) allows us to study the scaling of the transient time of large networks of more than a hundred nodes, which has not yet been confirmed previously in an experiment and could potentially be important in many natural networks. We find that the average transient time increases exponentially with the network size and can be modeled as a Poisson process in experiment and simulation. This exponential scaling is a result of a synchronization rate that follows a power law of the phase-space volume.

description: Objective Previous studies have confirmed Slug as a key player in regulating phenotypic changes in several cell models, however, its role in smooth muscle cells (SMC) has never been assessed. The purpose of this study was to evaluate the expression of Slug during the phenotypic switch of SMC in vitro and throughout the development of vascular remodeling. Methods and Results Slug expression was decreased during both cell-to-cell contact and TGF beta 1 induced SMC differentiation. Tumor necrosis factor-alpha (TNF alpha), a known inductor of a proliferative/dedifferentiated SMC phenotype, induces the expression of Slug in SMC. Slug knockdown blocked TNF alpha-induced SMC phenotypic change and significantly reduced both SMC proliferation and migration, while its overexpression blocked the TGF beta 1-induced SMC differentiation and induced proliferation and migration. Genome-wide transcriptomic analysis showed that in SMC, Slug knockdown induced changes mainly in genes related to proliferation and migration, indicating that Slug controls these processes in SMC. Notably, Slug expression was significantly up-regulated in lungs of mice using a model of pulmonary hypertension-related vascular remodeling. Highly remodeled human pulmonary arteries also showed an increase of Slug expression compared to less remodeled arteries. Conclusions Slug emerges as a key transcription factor driving SMC towards a proliferative phenotype. The increased Slug expression observed in vivo in highly remodeled arteries of mice and human suggests a role of Slug in the pathogenesis of pulmonary vascular diseases.

description: In 1952, Littlewood stated a conjecture about the average growth of spherical derivatives of polynomials, and showed that it would imply that for entire function of finite order, "most" preimages of almost all points are concentrated in a small subset of the plane. In 1988, Lewis and Wu proved Littlewood's conjecture. Using techniques from complex dynamics, we construct entire functions of finite order with a bounded set of singular values for which the set of exceptional preimages is infinite, with logarithmically growing cardinality.

description: In the second volume of “An introduction to Probability Theory and Its Applications”, Feller (1966) proved de Finetti’s Representation Theorem for infinite sequences of exchangeable {0, 1}-random variables via the solution to the Hausdorff Moment Problem over the unit line. It can be shown that the above problems are actually equivalent, i.e. an infinite sequence of {0, 1}-random variables is exchangeable if and only if the corresponding Hausdorff Moment Problem over the unit line has a solution. The Hausdorff Moment Problem has long been studied and the theory extends to multiple variables over various domains, while the concepts of Exchangeability are also vastly extended. This gave rise to the idea of the current thesis, aiming to draw some connections between the different cases of Problems of Moments and the concepts of Exchangeability.

description: Fatal neurodegenerative disorders termed transmissible spongiform encephalopathies (TSEs) are associated with the accumulation of fibrils of misfolded prion protein PrP. The noble gas xenon accommodates into four transiently enlarged hydrophobic cavities located in the well-folded core of human PrP(23-230) as detected by [H-1, N-15]-HSQC spectroscopy. In thermal equilibrium a fifth xenon binding site is formed transiently by amino acids A120 to L125 of the presumably disordered N-terminal domain and by amino acids K185 to T193 of the well-folded domain. Xenon bound PrP was modelled by restraint molecular dynamics. The individual microscopic and macroscopic dissociation constants could be derived by fitting the data to a model including a dynamic opening and closing of the cavities. As observed earlier by high pressure NMR spectroscopy xenon binding influences also other amino acids all over the N-terminal domain including residues of the AGAAAAGA motif indicating a structural coupling between the N-terminal domain and the core domain. This is in agreement with spin labelling experiments at positions 93 or 107 that show a transient interaction between the N-terminus and the start of helix 2 and the end of helix 3 of the core domain similar to that observed earlier by Zn2+-binding to the octarepeat motif.

description: Many-body entanglement is at the heart of the Kondo effect, which has its hallmark in quantum dots as a zero-bias conductance peak at low temperatures. It signals the emergence of a conducting singlet state formed by a localized dot degree of freedom and conduction electrons. Carbon nanotubes offer the possibility to study the emergence of the Kondo entanglement by tuning many-body correlations with a gate voltage. Here we show another side of Kondo correlations, which counterintuitively tend to block conduction channels: inelastic co-tunnelling lines in the magnetospectrum of a carbon nanotube strikingly disappear when tuning the gate voltage. Considering the global SU(2) circle times SU(2) symmetry of a nanotube coupled to leads, we find that only resonances involving flips of the Kramers pseudospins, associated to this symmetry, are observed at temperatures and voltages below the corresponding Kondo scale. Our results demonstrate the robust formation of entangled many-body states with no net pseudospin.

We observe 3 dB of spin squeezing and detect entanglement of up to $5.5\times10^5 $ atoms with $5σ$ statistical significance using a generalized spin squeezing inequality. The degree of squeezing implies at least 50% of the atoms have formed singlets, while the response to a magnetic field gradient indicates entanglement bonds at all length scales, a characteristic of quantum spin liquids.

Finite range and upper branch effects on itinerant ferromagnetism in repulsive Fermi gases: Bethe-Goldstone ladder resummation approach

description: We investigate the ferromagnetic transition in repulsive Fermi gases at zero temperature with upper branch and effective range effects. Based on a general effective Lagrangian that reproduces precisely the two-body $s$-wave scattering phase shift, we obtain a nonperturbative expression of the energy density as a function of the polarization by using the Bethe-Goldstone ladder resummation. For hard sphere potential, the predicted critical gas parameter $k_{\rm F}a=0.816$ and the spin susceptibility agree well with the results from fixed-node diffusion Monte Carlo calculations. In general, positive and negative effective ranges have opposite effects on the critical gas parameter $k_{\rm F}a$: While a positive effective range reduces the critical gas parameter, a negative effective range increases it. For attractive potential or Feshbach resonance model, the many-body upper branch exhibits an energy maximum at $k_{\rm F}a=α$ with $α=1.34$ from the Bethe-Goldstone ladder resummation, which is qualitatively consistent with experimental results. The many-body T-matrix has a positive-energy pole for $k_{\rm F}a>α$ and it becomes impossible to distinguish the bound state and the scattering state. These positive-energy bound states become occupied and therefore the upper branch reaches an energy maximum at $k_{\rm F}a=α$. In the zero range limit, there exists a narrow window ($0.86

description: We show that superconducting interlayer coupling, which coexists with and is depressed by stripe order in La1.885Ba0.115CuO4, can be enhanced by excitation with near-infrared laser pulses. For temperatures lower than Tc = 13 K, we observe a blue-shift of the equilibrium Josephson plasma resonance, detected by terahertz-frequency reflectivity measurements. Key to this measurement is the ability to probe the optical properties at frequencies as low as 150 GHz, detecting the weak interlayer coupling strengths. For T > Tc a similar plasma resonance, absent at equilibrium, is induced up to the spin-ordering temperature TSO = 40 K. These effects are reminiscent but qualitatively different from the light-induced superconductivity observed by resonant phonon excitation in La1.675Eu0.2Sr0.125CuO6.5. Importantly, enhancement of the below-Tc interlayer coupling and its appearance above Tc are preferentially achieved when the near-infrared pump light is polarized perpendicular to the superconducting planes, likely due to more effective melting of stripe order and the less effective excitation of quasiparticles from the Cooper pair condensate when compared to in-plane excitation.

description: We show that non-Abelian lattice gauge fields can be simulated with a single component ultra-cold atomic gas in an optical lattice potential. An optical lattice can be viewed as a Bravais lattice with a $N$-point basis. An atom located at different points of the basis can be considered as a {\it particle} in different internal states. The appropriate engineering of tunneling amplitudes of atoms in an optical lattice allows one to realize U$(N)$ gauge potentials and control a mass of {\it particles} that experience such non-Abelian gauge fields. We provide and analyze a concrete example of an optical lattice configuration that allows for simulation of a static U(2) gauge model with a constant Wilson loop and an adjustable mass of {\it particles}. In particular, we observe that the non-zero mass creates large conductive gaps in the energy spectrum, which could be important in the experimental detection of the transverse Hall conductivity.

description: En tant qu’enseignante de sciences et déléguée à la promotion de la santé et prévention en milieu scolaire (PSPS) dans mon établissement, je suis particulièrement intéressée par les premiers secours et les actions de prévention. Pour mon travail de mémoire, j’ai décidé de mener une étude dont l’objectif est de recueillir et analyser les représentations préalables des élèves concernant cette thématique dans le but de proposer des ateliers d’initiation aux premiers secours au plus près des besoins et des caractéristiques des élèves, afin qu’ils soient les plus efficaces possibles. L’analyse des réponses des élèves permet de mettre en évidence que chez les élèves de 11H de l’établissement de Genolier, les craintes concernant les gestes de premiers secours s’avèrent peu importantes. Les réactions dans des situations d’urgence se révèlent de deux types: soit les réactions sont centrées sur les gestes de premiers secours, soit elles sont tournées vers la personne qui a besoin d’aide. Des valeurs centrées sur autrui se dégagent également chez une partie des jeunes et certains adolescents pensent que la société attend d’eux un comportement modèle avec des valeurs tournées vers les autres, tandis que d’autres estiment que la société attend d’eux des valeurs de courage, et d’indépendance. Ils participent à ces ateliers dans le but d’augmenter leurs connaissances et leur confiance en eux dans des situations d’urgence. Cette recherche montre également qu'il existe une relation entre les valeurs centrées sur les autres et les réactions centrées sur les personnes chez les élèves et plusieurs facteurs tels que le genre, la voie ou le fait d’avoir suivi ou non préalablement un cours de samaritains peut influencer leur propension à agir avec des gestes de premiers secours. Ces adolescents ont en moyenne également d’assez bonnes connaissances de leur corps et des aspects liés aux gestes de premiers secours et les élèves avec un bon niveau de connaissances auront davantage tendance à agir dans une situation d’urgence. Questionner les élèves en amont d’une activité de prévention et de promotion de la santé permet donc de construire et d’organiser celle-ci, afin qu’elle n’apporte pas seulement des connaissances aux élèves, mais également qu’elle modifie les représentations de ces derniers.

description: A polarized abelian variety (X,λ) of dimension g over a local field K determines an admissible representation of GSpin_{2g+1}(K). We show that the restriction of this representation to Spin_{2g+1}(K) is reducible if and only if X is isogenous to its twist by the quadratic unramified extension of K. When g=1 and K = Q_p, we recover the well-known fact that the admissible GL_2(K) representation attached to an elliptic curve E is reducible upon restriction to SL_2(K) if and only if E has supersingular reduction.

description: A common culture existed across Britain, Ireland and western Europe six thousand years ago. Writing came into being in Wales 4,270 BC, Irish symbols portrayed Sun and Moon calendars 3,500 BC. Arithmetic and geometry developed in Denmark 3,100 BC, Scandinavians navigated the oceans using a sixty-four point compass. France’s Carnac stone rows exhibit Sun and Moon calendars counts, linear measures. Brython’s [Wales] and Cornwall’s Bronze Age 2,000 BC inaugurated mining, widespread copper and tin industries and commerce in Britain and across Europe. Five day weeks Sun and Moon calendars endured for four thousand years in the western Isles and Europe until the beginning of the Roman Empire two thousand years ago. This book is about how they came to be and how it was done in prehistoric times.

description: In topologically ordered quantum states of matter in 2+1D (space-time dimensions), the braiding statistics of anyonic quasiparticle excitations is a fundamental characterizing property which is directly related to global transformations of the ground-state wavefunctions on a torus (the modular transformations). On the other hand, there are theoretical descriptions of various topologically ordered states in 3+1D, which exhibit both point-like and loop-like excitations, but systematic understanding of the fundamental physical distinctions between phases, and how these distinctions are connected to quantum statistics of excitations, is still lacking. One main result of this work is that the three-dimensional generalization of modular transformations, when applied to topologically ordered ground states, is directly related to a certain braiding process of loop-like excitations. This specific braiding surprisingly involves three loops simultaneously, and can distinguish different topologically ordered states. Our second main result is the identification of the three-loop braiding as a process in which the worldsheets of the three loops have a non-trivial triple linking number, which is a topological invariant characterizing closed two-dimensional surfaces in four dimensions. In this work we consider realizations of topological order in 3+1D using cohomological gauge theory in which the loops have Abelian statistics, and explicitly demonstrate our results on examples with $Z_2\times Z_2$ topological order.

description: Galaxy clusters are predicted to produce gamma-rays through cosmic ray interactions and/or dark matter annihilation, potentially detectable by the Fermi Large Area Telescope (Fermi-LAT). We present a new, independent stacking analysis of Fermi-LAT photon count maps using the 78 richest nearby clusters (z<0.12) from the Two Micron All-Sky Survey (2MASS) cluster catalog. We obtain the lowest limit on the photon flux to date, 2.3e-11 ph/s/cm^2 (95% confidence) per cluster in the 0.8-100 GeV band, which corresponds to a luminosity limit of 3.5e44 ph/s. We also constrain the emission limits in a range of narrower energy bands. Scaling to recent cosmic ray acceleration and gamma-ray emission models, we find that cosmic rays represent a negligible contribution to the intra-cluster energy density and gas pressure.

description: Two new indicators of rainfall seasonality based on information entropy, the relative entropy (RE) and the dimensionless seasonality index (DSI), together with the mean annual rainfall, are evaluated on a global scale for recently updated precipitation gridded datasets and for historical simulations from coupled atmosphere-ocean general circulation models. The RE provides a measure of the number of wet months and, for precipitation regimes featuring one maximum in the monthly rain distribution, it is related to the duration of the wet season. The DSI combines the rainfall intensity with its degree of seasonality and it is an indicator of the extent of the global monsoon region. We show that the RE and the DSI are fairly independent of the time resolution of the precipitation data, thereby allowing objective metrics for model intercomparison and ranking. Regions with different precipitation regimes are classified and characterized in terms of RE and DSI. Comparison of different land observational datasets reveals substantial difference in their local representation of seasonality. It is shown that two-dimensional maps of RE provide an easy way to compare rainfall seasonality from various datasets and to determine areas of interest. CMIP5 models consistently overestimate the RE over tropical Latin America and underestimate it in Western Africa and East Asia. It is demonstrated that positive RE biases in a GCM are associated with simulated monthly precipitation fractions which are too large during the wet months and too small in the months preceding the wet season; negative biases are instead due to an excess of rainfall during the dry months.

Attorno alla nana rossa Gliese 486, a soli 26 anni luce da noi, orbita una super-Terra con una temperatura superficiale di circa 430 gradi Celsius. Osservando due transiti del pianeta, il telescopio spaziale James Webb ha rilevato tracce di vapore d’acqua, che potrebbe indicare la presenza di un’atmosfera attorno al pianeta. Saranno necessarie ulteriori osservazioni per capirne l'origine, se stellare o planetaria

description: Острая хирургическая патология у беременных представляет собой серьезную междисциплинарную проблему. Анатомо-физиологические особенности, связанные с беременностью, приводят к дефициту диагностической информации: «привычные» клинические симптомы и лабораторные признаки делаются малоинформативными, а применение инструментальных методов визуализации ограничивается противопоказаниями. Это значительно затрудняет принятие решения в отношении как хирургической, так и акушерской тактики. Повышенная ответственность и морально-этическая сторона принятия такого решения требуют проведения консилиумов с участием наиболее опытных специалистов. С совершенствованием современных технологий патогенетической коррекции проявлений сочетанного токсикоза требует уточнения роль применения экстракорпоральных методов детоксикации у беременных с хирургической патологией. При абдоминальном родоразрешении пациенток, оперированных во время беременности по поводу острой абдоминальной патологии, все большее распространение получает методика экстраперитонеальных вмешательств. Требует изучения проблема отдаленных результатов перенесенных во время беременности хирургических заболеваний, качества жизни и фертильности у этой группы пациенток.

description: Abstract
Farman, 2023, Doctoral Study Program in Law, Diponegoro University. "Reconstruction of Policy for Combating Drug Crimes Based on Justice Values". This study aims to examine 1) How is the implementation of criminal sanctions policies and actions in law enforcement against drug crimes today? 2) What are the weaknesses in the application of criminal sanctions policies and actions in law enforcement over drug crimes? 3) How Reconstruction of drug crime prevention policies based on the value of justice. The research method used is the juridical-normative method with a statutory approach, a concept approach, and a comparative approach. The results showed that; 1) The policy of criminal sanctions and actions in law enforcement against drug crimes currently does not meet the elements of justice, because there are still several obstacles in its implementation, including; a) Not Achieving the Goal of Criminalization: Deterrent Effect, b) Not Achieving the Goal of Criminalization: User and Community Health, c) Principle of Costs and Results: High Costs of Criminalization and Lack of Results, d) Unclear terms abusers, addicts, drug victims have an impact on criminal sanctions and rehabilitation, e) Criminalization of parents and the community who do not report becomes less effective in law enforcement against drug eradication. 2) Weaknesses in the Criminal Sanctions Policy in Law Enforcement for Combating Drug Crimes in Indonesia, including; a) Unclear definition and status between addicts, abusers, and victims of narcotics abuse, b) abusers are subject to punishment and lose their rehabilitation rights, unless they can be proven or proven to be narcotics victims, c) are not clearly regulated regarding addicts who violate the law by addicts who are not against the law, d) Confusion of Unlawful Criminal Offenses with elements of "controlling",  "possessing", "keeping", and/or "buying" narcotics, e) Not attaching importance to intentional elements in narcotic crime, f) Criminalization for people parents and people who do not report, g) Equality of Sentences for Trials and Crimes Completed. 3) Reconstruction of Criminal Sanctions Policy in Law Enforcement for Combating Drug Crimes in Indonesia can be carried out in the following ways: a) Confirmation of the Terms of Definition and Status between Addicts, Abusers, and Victims of Narcotics Abuse, b) Affirmation of Rehabilitation Rights for Drug Abusers and Drug Victims , c) Affirmation of the term drug users who are against the law with users who are not against the law,  d) affirmation of the element of intent in narcotics crimes, e) affirmation of unlawful criminal offenses with elements of "controlling", "possessing", "keeping", and or "buying" narcotics, f) Elimination of criminalization for parents and the community with other methods, g) Given different punishments for probation and completed criminal acts
