description: Ce mémoire professionnel traite de l’évolution des modalités d’évaluation en l’éducation physique et sportive. Au travers de ce travail de recherche, une approche historique basée plus particulièrement sur l’évaluation de cette branche dans les classes du secondaire I du canton de Vaud, est adoptée. Il s’agit ainsi d’une analyse des caractéristiques de cette évolution, de ses étapes spécifiques et bien entendu du contexte dans lequel d’insèrent ces différents changements, entre 1940 et 2010. En outre, ce texte s’articule autour de cinq différents indicateurs liés aux modalités d’évaluation. Le contenu, les critères d’évaluations, l’identité et les fonctions énoncées de l’évaluation, la place de l’évaluation dans les processus pédagogiques et didactiques et finalement le statut de l’élève accordé au travers des différents documents d’évaluations et notamment celui des filles sont des thématiques développées dans ce travail. Ainsi, l’analyse de sources telles que des textes prescriptifs fédéraux publiés dans le Bulletin officiel du Département de l’instruction publique et des cultes depuis 1940 ou des livrets d’évaluation successivement édités par le Canton semble pouvoir apporter un nouvel angle d’étude à la thématique. L’évaluation et plus précisément l’évolution de ses modalités sous-jacentes, semble ainsi pouvoir être comprise comme un reflet plus ou moins déformé du développement identitaire de l’éducation physique, propre au contexte national et cantonal dans lequel cette branche s’insère, comme une tentatives de réponses à un contexte politique, éducatif et culturel spécifique à la discipline et aux périodes associées. Au travers de l’analyse de ces différents indicateurs, certaines tendances peuvent être soulignées. Ainsi, cette recherche montrent que l’évolution des modalités d’évaluation associés à l’éducation physique, branche qui n’a pas de valeur certificative dans le canton, est caractérisée par une certaine inertie. En effet, les différentes démarches et ruptures peuvent être distinguées par la recherche constante d’adaptation et de compromis dans le but de faire progressivement coexister les différentes finalités attribuées à l’éducation physique, mais sans pour autant transformer radicalement les habitudes liées à l’évaluation. Ainsi, ce nouvel angle d’analyse semble pouvoir à son tour illustrer les spécificités ainsi que la complexité qui entoure le statut et le processus d’institutionnalisation de l’éducation physique au niveau cantonal.

description: We provide and discuss the precision predictions for the $W^+W^-γ$ production at the ILC including the full electroweak (EW) one-loop corrections and high order initial state radiation (ISR) contributions in the Standard Model. The dependence of the leading order (LO) and EW corrected cross sections on the colliding energy is investigated. We find that the EW correction suppresses the LO cross section significantly, and the ISR effect beyond ${\cal O}(α)$ is important near the threshold, but is negligible in the high energy region. We provide the LO and EW corrected distributions of the transverse momenta and rapidities of final $W^-$-boson and photon as well as the $W$-pair invariant mass. From the various kinematic distributions, we find that EW correction strongly depends on the final state phase space. We investigate the leptonic decays of the final W-boson pair by adopting the narrow width approximation (NWA), and find that the final produced photon and leptons can be well separated from each other.

description: We present the completed catalog of ultra-diffuse galaxy (UDG) candidates (7070 objects) from our search of the DR9 Legacy Survey images, including distance and total mass estimates for 1529 and 1436 galaxies, respectively, that we provide and describe in detail. From the sample with estimated distances, we obtain a sample of 585 UDGs ($μ_{0,g} \ge 24$ mag arcsec$^{-2}$ and $r_e \ge 1.5$ kpc) over 20,000 sq. deg of sky in various environments. We conclude that UDGs in our sample are limited to $10^{10} \lesssim$ M$_h$/M$_\odot \lesssim 10^{11.5}$ and are on average a factor of 1.5 to 7 deficient in stars relative to the general population of galaxies of the same total mass. That factor increases with increasing galaxy size and mass up to a factor of $\sim$10 when the total mass of the UDG increases beyond M$_h = 10^{11}$ M$_\odot$. We do not find evidence that this factor has a dependence on the UDG's large-scale environment.

description: We report on a detailed abundance study of six bright, mostly southern, slowly rotating late B stars: HD~1279 (B8III), HD~99803 (B9V), HD~123445 (B9V), HD~147550 (B9V), HD~171961 (B8III) and HD~202671 (B5II/III), hitherto reported as normal stars. We compare them to the two classical HgMn stars $μ$ Lep and $β$ Scl and to the superficially normal star, $ν$ Cap. In the spectra of the six stars, the \ion{Hg}{2} line at 3984 Å line is clearly seen and numerous lines of P, Ti, Mn, Fe, Ga, Sr, Y, and Zr appear to be strong absorbers. A comparison of newly acquired and archival spectra of these objects with a grid of synthetic spectra for selected unblended lines reveals large overabundances of P, Ti, Cr, Mn, Sr, Y, Zr, Ba, Pt and Hg and underabundances of He, Mg, Sc and Ni. The effective temperatures, surface gravities, low projected rotational velocities and the peculiar abundance patterns of the six investigated stars show that they are new chemically peculiar stars, mostly new HgMn stars, and are reclassified as such. The evolutionary status of these stars has been inferred and their ages and masses estimated. The two most massive objects, HD~1279 and HD~202671, might have evolved away from the main-sequence recently, the other stars are main-sequence objects. HD~99803A is a sharp lined HgMn star with grazing eclipses; from TESS and MASCARA photometry we determine an orbital period of $P_{\rm orb} = 26.12022 \pm 0.00004$\,d.

Dip formation in the gravity-mode period spacing pattern: The magnetic picture

Publisher: name: Zenodo
Year: 2024

description: Understanding angular momentum transport is a major challenge for the theory of stellar evolution. Recent asteroseismic studies from Kepler detected dips in the gravity-mode period spacing vs period diagram of γ Doradus stars. One of the mechanisms causing such dips is the interaction of gravito-inertial modes in the radiative envelope with pure inertial modes in the convective core. In this work, we derive the effect of internal magnetic fields on the Lorentzian shape of the dip, magnetic fields being one of the main candidates to efficiently redistribute angular momentum throughout stellar evolution. For this, considering a toroidal magnetic topology corresponding to a uniform Alfvén frequency in the radiative envelope and in the convective core, we study the wave behavior in both regions and we demonstrate that the magneto-hydrodynamic coupling problem shows similarities with the pure hydrodynamic case. We identify the three main influences of the magnetic field: a shift of the average period spacing in the co-rotating frame, an additional decrease of the period spacing pattern in period, and a shift of the period of the dip in the inertial frame. We extend the study to non-Kelvin modes previously detected in γ Doradus stars. Our work demonstrates the remarkable potential of studying such dips to probe internal stellar magnetism and provides predictions for further detections in asteroseismic data.

description: Quelles sont les compétences de compréhension en lecture des élèves lorsqu'ils arrivent au secondaire 1 ? Sont-ils en mesure d'aborder n'importe quel texte narratif ? Quels processus et stratégies leur enseigner pour améliorer cette compréhension ? Telles sont les questions auxquelles nous avons tenté de répondre, en imaginant une séquence didactique pour nos classes. Le but de ce travail était donc d'une part d'interroger nos propres pratiques enseignantes quant à la manière d'aborder les textes avec nos élèves, et d'autre part de réaliser une séquence didactique qui soit en adéquation avec les objectifs du PER et qui nous permette de réellement enseigner des stratégies. Nous nous sommes surtout basées sur deux auteurs spécialistes de cette problématique : Jocelyne Giasson et Roland Goigoux et avons élaboré des activités qui privilégient trois processus majeurs de la compréhension, à savoir les macro-processus (centrés sur les aspects globaux de la compréhension, sur la façon d'organiser des idées au sein d'un récit et sur la manière de repérer des informations importantes), les processus d'intégration (les liens, les connecteurs et les inférences) et les processus d'élaboration (permettant de faire des prédictions sur le texte et de se former une image mentale). Au vu des éléments de la progression des apprentissage que nous avions sélectionnés dans le PER, nous avons opté pour la lecture de textes narratifs. Souhaitant travailler sur un livre et non sur des extraits de texte, nous avons choisi le recueil de nouvelles policières Coule la Seine de Fred Vargas (2002), qui présentait l'avantage de contenir trois textes courts. Nous avons donc développé une séquence reprenant ces différents éléments. Ces activités ont été testées, puis critiquées en fonction de trois questions principales qui concernaient : la linéarité de la progression des tâches, les modalités d'enseignement favorisant une mise au travail et en7n un questionnement sur les tâches en elles-mêmes permettant ou non de d'apprendre ce qui était visé.

description: An archaeological excavation was undertaken on the site of St John's Car Park, St John's Street, Northampton, within the former precinct of the medieval Hospital of St John. Two clusters of medieval pits found were probably used for the disposal of domestic rubbish, and contained pottery dating from the 12th to the early 14th centuries. Assemblages of bone included meat-rich cuts from sheep and cattle, a variety of fish including both marine and freshwater species, and the presence of squirrel and cat may indicate the preparation of pelts for fur clothing. Botanical remains included the common range of cereals but also more unusual items such as figs, plums and cherries. It is possible, but by no means certain, that these remains relate to the diet and economy of the Hospital inhabitants. Later features included a wall probably relating to an 18th-century building, and pits and wells containing 19th-century rubbish.

description: Chaque enseignant d’éducation physique à sa vision personnelle de l’enseignement et a des valeurs qui lui sont propres. Le terme d’orientation de valeur a été inventé par Eisner et Vallance (1974). Puis Jewett et Bain (1985) ont repris ces orientations de valeurs pour l’enseignement de l’éducation physique. Il existe cinq orientations de valeurs : maîtrise de la discipline (MD), responsabilisation sociale (RS), processus d’apprentissage (PA), auto- actualisation (AA) et intégration écologique (IE). Nous avons voulus comparer ces différentes orientations de valeurs entre les enseignants suisses (canton de Vaud) et les enseignants américains et observer si des différences significatives existaient. Les hypothèses de notre travail sont les suivantes : les enseignants américains sont plus axés sur l’OV MD alors que les enseignants suisses le sont davantage sur PA. Ensuite, le genre aurait une influence sur les orientations de valeurs, et cela entre les pays et à l’intérieur des deux pays concernés. Les femmes accorderaient plus d’importance aux orientations de valeurs RS et AA par rapport aux hommes. De plus les femmes accorderaient moins d’importance à MD que les hommes. Notre troisième hypothèse est qu’autant aux États-Unis qu’en Suisse, les années d’expérience ont une influence sur les orientations de valeur et plus précisément sur MD. Les résultats montrent qu’il existe une différence au niveau de MD et PA entre les enseignants américains et suisses. Ces derniers sont plus importants aux Etats-Unis. Concernant RS, cette orientation de valeur est davantage préconisée en Suisse. Dans la comparaison entre les orientations de valeur et le genre, aucune différence statistiquement significative n’a été relevée entre les hommes et les femmes pour toutes les orientations de valeurs. Cependant, en comparant les hommes et les femmes à l’intérieur de leurs pays respectifs, nous notons des différences significatives pour MD (pour les Américains) et IE (pour les Suisses). Les orientations de valeurs des enseignants d’éducation physique diffèrent donc sensiblement d’un pays à l’autre et plus particulièrement, dans la présente étude, entre la Suisse et les Etats- Unis.

description: Understanding network flows such as commuter traffic in large transportation networks is an ongoing challenge due to the complex nature of the transportation infrastructure and of human mobility. Here we show a first-principles based method for traffic prediction using a cost based generalization of the radiation model for human mobility, coupled with a cost-minimizing algorithm for efficient distribution of the mobility fluxes through the network. Using US census and highway traffic data we show that traffic can efficiently and accurately be computed from a range-limited, network betweenness type calculation. The model based on travel time costs captures the lognormal distribution of the traffic and attains a high Pearson correlation coefficient (0.75) when compared to real traffic. Due to its principled nature, this method can inform many applications related to human mobility driven flows in spatial networks, ranging from transportation, through urban planning to mitigation of the effects of catastrophic events.

description: Delivering a reproducible environment along with complex and up-to-date software stacks on thousands of distributed and heterogeneous worker nodes is a critical task. The CernVM-File System (CVMFS) has been designed to help various communities to deploy software on worldwide distributed computing infrastructures by decoupling the software from the Operating System. However, the installation of this file system depends on a collaboration with system administrators of the remote resources and an HTTP connectivity to fetch dependencies from external sources. Supercomputers, which offer tremendous computing power, generally have more restrictive policies than grid sites and do not easily provide the mandatory conditions to exploit CVMFS. Different solutions have been developed to tackle the issue, but they are often specific to a scientific community and do not deal with the problem in its globality. In this paper, we provide a generic utility to assist any community in the installation of complex software dependencies on supercomputers with no external connectivity. The approach consists in capturing dependencies of applications of interests, building a subset of dependencies, testing it in a given environment, and deploying it to a remote computing resource. We experiment this proposal with a real use case by exporting Gauss-a Monte-Carlo simulation program from the LHCb experiment-on Mare Nostrum, one of the top supercomputers of the world. We provide steps to encapsulate the minimum required files and deliver a light and easy-to-update subset of CVMFS: 12.4 Gigabytes instead of 5.2 Terabytes for the whole LHCb repository.

description: For a non-empty ground set $X$, finite or infinite, the {\em set-valuation} or {\em set-labeling} of a given graph $G$ is an injective function $f:V(G) \to \mathcal{P}(X)$, where $\mathcal{P}(X)$ is the power set of the set $X$. A set-indexer of a graph $G$ is an injective set-valued function $f:V(G) \to \mathcal{P}(X)$ such that the function $f^{\ast}:E(G)\to \mathcal{P}(X)-\{\emptyset\}$ defined by $f^{\ast}(uv) = f(u){\ast} f(v)$ for every $uv{\in} E(G)$ is also injective., where $\ast$ is a binary operation on sets. An integer additive set-indexer (IASI) is defined as an injective function $f:V(G)\to \mathcal{P}({\mathbb{N}_0})$ such that the induced function $g_f:E(G) \to \mathcal{P}(\mathbb{N}_0)$ defined by $g_f (uv) = f(u)+ f(v)$ is also injective, where $\mathbb{N}_0$ is the set of all non-negative integers and $\mathcal{P}(\mathbb{N}_0)$ is its power set. A weak IASI is an IASI $f$ such that $|f^+(uv)|= \text{max}(f(u),f(v))$. In this paper, we critically and creatively review the concepts and properties of weak integer additive set-valued graphs.

description: Dans le système de formation suisse, l’école obligatoire s’achève avec la fin du Secondaire I. Pour l’essentiel, ce dernier est structuré en deux filières dites à "exi- gences élémentaire" et à "exigences étendues". Le Secondaire II qui lui succède s’articule autour de deux types de formations, à savoir les formations générales (écoles de maturité ou de culture générale) et les formations professionnelles (apr- rentissages, écoles techniques). La répartition des élèves entre ces deux types de formations varie de façon si- gnificative d’un canton à l’autre. Ce travail statistique s’intéresse à la source de cette hétérogénéité et met en évidence le rôle important joué par l’aspect culturel dans ce phénomène à l’aide d’une étude corrélative. Les résultats montrent qu’une certaine cohérence (inexistante au niveau national) dans le choix des élèves issus d’une filière à exigences étendues au Secondaire I peut être mise en lumière dès lors que l’on échantillonne séparément les cantons romands des cantons alémaniques. L’importance de l’aspect culturel tend à se confirmer par le fait que les jeunes romands empruntent une voie très similaire à leurs homologues français résidents de façon permanente en suisse. De même, les choix des suisse alémaniques s’appa- rentent à ceux faits par les allemands qui vivent dans notre pays et ceux des tessinois à ceux des résidents italiens. Enfin, ce travail montre que les étrangers résidents permanents, dans leur en- semble, augmentent de façon non négligeable le nombre des jeunes qui s’orientent vers une formation professionnelle ; cet effet, relativement faible au niveau national, s’avère non-négligeable dans le canton de Vaud.

description: This article presents a brief overview of our recent work on the nature of long period modulation in the premartensite and martensite phases of Ni2MnGa ferromagnetic shape memory alloy using high resolution synchrotron x-ray powder diffraction patterns. The commensurate structure model using the Pnnm space group is unable to account for the peak positions of the satellite reflections that appear due to modulations correctly. LeBail and Rietveld refinements using the (3+1)-D super space group $Immm(00γ)s00$ show that the peak positions of all the reflections, including the satellites, can be explained satisfactorily using incommensurate modulations for both the premartensite and martensite phases. The incommensurate modulation vectors are found to be q= 0.33761(5)c* = (1/3+$δ$1)c* and 0.43160(3)c*= (3/7+$δ$2)c*, where $δ$1 and $δ$2 are the degrees of incommensuration for the premartensite and martensite phases, respectively. The periodicity of the closest rational approximant of the premartensite and martensite phases are confirmed to be 3M and 7M, respectively, in agreement with single crystal diffraction results.

description: We use four observations with the European VLBI network to measure the first precise radio parallax of the Crab Pulsar. We found two in-beam extragalactic sources just outside the Crab Nebula, with one bright enough to use as a background reference source in our data. We use the Crab Pulsar's giant pulses to determine fringe and bandpass calibration solutions, which greatly improved the sensitivity and reliability of our images and allowed us to determine precise positional offsets between the pulsar and the background source. From those offsets, we determine a parallax of $π=0.53\pm0.06\rm{\;mas}$ and proper motion of $(μ_α,μ_δ)=(-11.34\pm0.06,2.65\pm0.14)\rm{\;mas\;yr^{-1}}$, yielding a distance of $d=1.90^{+0.22}_{-0.18}\rm{\;kpc}$ and transverse velocity of $v_{\perp}=104^{+13}_{-11}\rm{\;km\;s^{-1}}$. These results are consistent with the Gaia 3 measurements, and open up the possibility of far more accurate astrometry with further VLBI observations.

description: This article considers the Dissertatio de Arte Combinatoria, published in 1666 and relatively neglected by Leibniz s scholars. However in recent times the tide seems to be changing. Our work presents three main parts (sections II, III and IV, respectively). The first one exposes the contributions of M. Serres and E. Knobloch, viewed from our stand-point. The second one emphazises the role played by the symmetric group as the underlying mathematical structure of the Opus. Finally we treat the caput variationis which, in our opinion, is the fundamental concept of the Dissertatio. Moreover, it is suggested that the importance of such a theoretical insight may be traced in many aspects of Leibniz s subsequent thought.

description: The interaction between the ejecta of supernovae (SNe) of Type IIn and a dense circumstellar medium (CSM) can efficiently generate thermal UV/optical radiation and lead to the emission of neutrinos in the $1$-$10^{3}$~TeV range. We investigate the connection between the neutrino signal detectable at the IceCube Neutrino Observatory and the electromagnetic signal observable by optical wide-field, high-cadence surveys to outline the best strategy for upcoming follow-up searches. We outline a semi-analytical model that connects the optical lightcurve properties to the SN parameters and find that a large peak luminosity (${L_{\rm{peak}}\gtrsim 10^{43}-10^{44}\,\mathrm{erg \,s^{-1}}}$) and an average rise time ($t_{\rm{rise}}\gtrsim 10-40$~days) are necessary for copious neutrino emission. Nevertheless, the most promising $ L_{\rm{peak}}$ and $t_{\rm{rise}}$ can be obtained for SN configurations that are not optimal for neutrino emission. Such ambiguous correspondence between the optical lightcurve properties and the number of IceCube neutrino events implies that relying on optical observations only, a range of expected neutrino events should be considered (e.g.~the expected number of neutrino events can vary up to two orders of magnitude for some among the brightest SNe IIn observed by the Zwicky Transient Facility up to now, SN 2020usa and SN 2020in). In addition, the peak in the high-energy neutrino curve should be expected a few $t_{\rm{rise}}$ after the peak in the optical lightcurve. Our findings highlight that it is crucial to infer the SN properties from multi-wavelength observations rather than focusing on the optical band only to enhance upcoming neutrino searches.

Persistent Identifier

description: The Open Researcher and Contributor ID ORCID strives to enable transparent and trustworthy connections between researchers, their contributions, and their affiliations by providing a unique, persistent identifier for individuals to use as they engage in research, scholarship, and innovation activities. ORCID is therefore an essential piece of the puzzle for increasing the discoverability of researchers by disambiguating them from all the other researchers with the same or even a similar name and definitively connecting them with their research contribution metadata (e.g. their scholarly record). Furthermore, ORCID specifically addresses each of the FAIR findability principle components. The international non-profit organization ORCID, on which the initiative is based, already connects over 14 million persons worldwide with their research outcomes. In order to promote the widespread implementation of ORCID at universities and non-university research institutions in Germany, the project "ORCID DE" was launched and is funded by the German Research Foundation (DFG). With the development of claiming services for the national bibliography of the German National Library and the BASE (Bielefeld Academic Search Engine), one of the world's most voluminous search engines especially for academic web resources, ORCID DE provides central tools for shaping the distribution and quality of metadata of scholarly communication from Germany. Furthermore the project fosters the interconnection of ORCID with other persistent identification (PID) systems and therefore contributes to more discoverability, accessibility, and visibility of research outcomes. As coordinator of the project, the Helmholtz Open Science Office makes an important contribution to improving scientific information management in the context of Open Science Further project partners of ORCID DE are Deutsche Nationalbibliothek, Universitätsbibliothek Bielefeld, DataCite - International Data Citation Initiative e. V. and Technische Informationsbibliothek (TIB) Hannover.

description: Διεθνώς, η συζήτηση για την ηγεσία στη σχολική μονάδα έχει γίνει πιο έντονη τις τελευταίες δεκαετίες. Οι σχετικοί προβληματισμοί εκφράζονται και στη χώρα μας, καθώς το κράτος και οι αντίστοιχοι φορείς αναζητούν την επιλογή των κατάλληλων Διευθυντών Σχολικών Μονάδων. Αυτή η αναζήτηση γίνεται ολοένα και πιο σημαντική καθώς το σχολικό περιβάλλον αλλάζει ραγδαία, θέτοντας περισσότερες απαιτήσεις από τη σχολική ηγεσία. Στο πλαίσιο της παρούσας ερευνητικής εργασίας που υλοποιήθηκε κατά τους μήνες Σεπτέμβριο-Νοέμβριο 2022 σε ένα δείγμα 164 εκπαιδευτικών όλων των ειδικοτήτων από 15 Σχολεία της Διεύθυνσης Δευτεροβάθμιας Εκπαίδευσης Μεσσηνίας γίνεται μια προσπάθεια αποτύπωσης, μέσα από την οπτική και τις απόψεις των εκπαιδευτικών, των χαρακτηριστικών και των δεξιοτήτων που διακρίνουν τον διευθυντή – ηγέτη της σχολικής μονάδας. Πολλά στοιχεία της παγκόσμιας βιβλιογραφίας υποδεικνύουν την ανάγκη ο σημερινός διευθυντής της σχολικής μονάδας να εγκαταλείψει τα προηγούμενα πρότυπα, να μην αρκείται μόνο στη διοικητική εργασία, αλλά να εξελιχθεί σε ηγετική φιγούρα.
description: Internationally, the debate on leadership in the school unit has become more intense in recent decades. The relevant concerns are also expressed in our country, as the state and the respective agencies are looking for the selection of the appropriate Headmasters of School Units. This search is becoming increasingly important as the school environment changes rapidly, placing more demands on school leadership. In the context of this research work that was implemented during the months of September-November 2022 in a sample of 164 teachers of all specialties from 15 Schools of the Directorate of Secondary Education of Messinia, an attempt is made to capture, through the perspectives and opinions of the teachers, the characteristics and skills that distinguish the director – leader of the school unit. Many elements of the world literature indicate the need for the current head of the school unit to abandon the previous standards, not to be satisfied only with administrative work, but to develop into a leading figure.
Influence of Electron-Impact Multiple Ionization on Equilibrium and Dynamic Charge State Distributions: A Case Study Using Iron

description: We describe the influence of electron-impact multiple ionization (EIMI) on the ionization balance of collisionally ionized plasmas. We are unaware of any previous ionization balance calculations that have included EIMI, which is usually assumed to be unimportant. Here, we incorporate EIMI cross-section data into calculations of both equilibrium and non-equilibrium charge-state distributions (CSDs). For equilibrium CSDs, we find that EIMI has only a small effect and can usually be ignored. However, for non-equilibrium plasmas the influence of EIMI can be important. In particular, we find that for plasmas in which the temperature oscillates there are significant differences in the CSD when including versus neglecting EIMI. These results have implications for modeling and spectroscopy of impulsively heated plasmas, such as nanoflare heating of the solar corona.

description: Moiré lattices are aperiodic systems formed by a superposition of two periodic lattices with a relative rotational angle. In optics, the photonic moiré lattice has many appealing properties such as its ability to localize light, thus attracting much attention on exploring features of such a structure. One fundamental research area for photonic moiré lattices is the properties of eigenstates, particularly the existence of localized eigenstates and the localization-to-delocalization transition in the energy band structure. Here we propose an accurate algorithm for the eigenproblems of aperiodic systems by combining plane wave discretization and spectral indicator validation under the higher-dimensional projection, allowing us to explore energy bands of fully aperiodic systems. A localization-delocalization transition regarding the intensity of the aperiodic potential is observed and a novel Pythagoras superposition principle for localized eigenstates of 2D moiré lattices is revealed by analyzing the relationship between the aperiodic and its corresponding periodic eigenstates. This principle sheds light on exploring the physics of localizations for moiré lattice.

description: In this paper the author compares behaviors of systems which can be described by fractional differential and fractional difference equations using the fractional and fractional difference Caputo Standard $α$-Families of Maps as examples. The author shows that properties of fractional difference maps (systems with falling factorial-law memory) are similar to the properties of fractional maps (systems with power-law memory). The similarities (types of attractors, power-law convergence of trajectories, existence of cascade of bifurcations and intermittent cascade of bifurcations type trajectories, and dependence of properties on the memory parameter $α$) and differences in properties of falling factorial- and power-law memory maps are investigated.

description: Le présent mémoire professionnel traite de la pertinence et des modalités d’un enseignement de la presse en école professionnelle dans le cadre de l’enseignement de la culture générale (ECG). Un examen des prescriptions du plan d’études cadre pour la culture générale (PEC CG) et des plan d’études école de cinq écoles professionnelles vaudoises amène à constater la possibilité d’un tel enseignement et une volonté effective de la réaliser dans quatre établissements. Un aperçu des pratiques enseignantes révèle toutefois que la presse constitue avant tout un moyen d’enseignement et rarement un thème à part entière du programme d’ECG. À partir d’une critique de la pratique actuelle et plus particulièrement du caractère doxique de l’usage instrumental de la presse dans les cours d’ECG, l’auteur dégage les enjeux fondamentaux d’un enseignement de la presse et les traduits en objectifs conformes aux prescriptions fédérales et locales. Il propose ensuite une séquence thématique transversale et modulable, censée ainsi être adaptable à toute école professionnelle du fait notamment de sa conformité au PEC CG, avant de conclure à la nécessité de la compléter par une autre séquence traitant globalement des stratégies de recherche, de sélection et de traitement de l’information, tous supports techniques confondus, qui devrait idéalement précéder immédiatement la réalisation du travail personnel d’approfondissement de fin de formation.

description: The $^{10}$B(p,$α_0$)$^7$Be bare nucleus astrophysical S(E)-factor has been measured for the first time at energies from about 100 keV down to about 5 keV by means of the Trojan Horse Method (THM). In this energy region, the S(E)-factor is strongly dominated by the 8.699 MeV $^{11}$C level (J$^π$=$\frac{5}{2}$$^+$), producing an s-wave resonance centered at about 10 keV in the entrance channel. Up to now, only the high energy tail of this resonant has been measured, while the low-energy trend is extrapolated from the available direct data. The THM has been applied to the quasi-free $^2$H($^{10}$B,$α_0$$^7$Be)n reaction induced at a boron-beam energy of 24.5 MeV. An accurate analysis brings to the determination of the $^{10}$B(p,$α_0$)$^7$Be S(E)-factor and of the corresponding electron screening potential $U_e$, thus giving for the first time an independent evaluation of it.

Meterwavelength Single-pulse Polarimetric Emission Survey. VI. Towards understanding the Phenomenon of Pulsar Polarization in Partially Screened Vacuum Gap model

description: We have observed 123 pulsars with periods longer than 0.1 seconds in the Meterwavelength Single-pulse Polarimetric Emission Survey. In this work a detailed study of polarization behaviour of these pulsars have been carried out. We were able to fit the rotating vector model to the polarization position angle sweeps in 68 pulsars, and in 34 pulsars the emission heights could be measured. In all cases the radio emission was constrained to arise below 10\% of the light cylinder radius. In pulsars with low spindown energy loss, $\dot{E}<10^{34}$ ergs s$^{-1}$, we found the mean fractional linear polarization of the individual times samples in single pulses to be around 0.57 (57\%) which is significantly larger than the fractional linear polarization of 0.29 (29\%) obtained from the average profiles. On the other hand the mean fractional circular polarization of the individual time samples in single pulses is around 0.08 (8\%), similar to the measurements from the average profiles. To explain the observed polarization features, we invoke the partially screened vacuum gap model of pulsars, where dense spark associated plasma clouds exist with high pair plasma multiplicity, with significant decrease of density in the regions between the clouds, that are dominated by iron ions. The coherent radio emission is excited by curvature radiation from charge bunches in these dense plasma clouds and escape as linearly polarized waves near cloud boundaries. We suggest that the circular polarization arises due to propagation of waves in the low pair multiplicity, ion dominated inter-cloud regions.
