description: Recent exo-planetary surveys reveal that planets can orbit and survive around binary stars. This suggests that some fraction of young binary systems which possess massive circumbinary disks (CB) may be in the midst of planet formation. However, there are very few CB disks detected. We revisit one of the known CB disks, the UY Aurigae system, and probe 13CO 2-1, C18O 2-1, SO 5(6)-4(5) and 12CO 3-2 line emission and the thermal dust continuum. Our new results confirm the existence of the CB disk. In addition, the circumstellar (CS) disks are clearly resolved in dust continuum at 1.4 mm. The spectral indices between the wavelengths of 0.85 mm and 6 cm are found to be surprisingly low, being 1.6 for both CS disks. The deprojected separation of the binary is 1.26" based on our 1.4 mm continuum data. This is 0.07" (10 AU) larger than in earlier studies. Combining the fact of the variation of UY Aur B in $R$ band, we propose that the CS disk of an undetected companion UY Aur Bb obscures UY Aur Ba. A very complex kinematical pattern inside the CB disk is observed due to a mixing of Keplerian rotation of the CB disk, the infall and outflow gas. The streaming gas accreting from the CB ring toward the CS disks and possible outflows are also identified and resolved. The SO emission is found to be at the bases of the streaming shocks. Our results suggest that the UY Aur system is undergoing an active accretion phase from the CB disk to the CS disks. The UY Aur B might also be a binary system, making the UY Aur a triple system.

description: En s’intéressant au processus d’orientation en fin de 8ème Harmos, ce mémoire professionnel tente de cerner les indices aux travers desquels les enseignants façonnent leurs choix afin d’orienter les élèves. Ce travail s’intéresse aux deux lois mises en œuvre dans le canton de Vaud ces dernières années, soit Ecole Vaudoise en Mutation (EVM) et la Loi sur l’Enseigement Obligatoire (LEO). Par analogie, cette recherche met en exergue les effets que ce changement de loi a apportés sur les pratiques enseignantes, d’où notre question de recherche : « Quels sont les effets de l’introduction de la LEO sur le processus d’orientation ? » Afin de répondre à cette question, nous avons mené cinq entretiens individuels avec des enseignants ayant orienté aussi bien sous EVM que sous la LEO. A partir de ceux-ci et des textes légaux, nous avons pu mettre en évidence les répercussions positives et négatives que cette mutation a apportées sur les différents acteurs de l’orientation : le corps enseignant, les parents et les élèves. Avec l’introduction de la LEO, tout le système subit des changements. En effet, les anciennes voies d’orientation en vigueur sous EVM ont été remplacées. Les élèves sont désormais orientés dans deux voies différentes, la voie prégymnasiale (VP) et la voie générale (VG). Cette nouvelle vision de l’école vaudoise a également vu la réintroduction du redoublement en fin de 8ème Harmos. En outre, les élèves ne sont pas les seuls acteurs touchés par cette modification de loi. Effectivement, le corps enseignant ainsi que les parents ont également subi ces changements. Le rôle des parents et des enseignants s’est vu anéanti lors de la décision d’orientation. Cette dernière est prise mécaniquement en se basant uniquement sur les notes.

description: People who inject drugs (PWID) are a population that disproportionately struggles with economic and mental health challenges. However, despite numerous reports of people globally experiencing new or exacerbated economic and/or mental health challenges during the COVID-19 pandemic, the literature on the effect of the pandemic on PWID and their risk for harm (e.g., overdose) remains sparse. The present study will describe reported changes during the pandemic in risk factors for drug overdose (including changes in mental health symptoms and care access) among PWID in Chicago, and it will examine associations between such risk factor changes and the experience of economic challenges during the pandemic. Participants from an ongoing longitudinal study of young PWID from the Chicago suburbs and their injection risk network members (N = 138; mean age = 28.7 years) were interviewed about changes in their experiences, substance use behavior, and mental health since the start of the COVID-19 pandemic. Bivariate cross tabulations were computed of each "overdose risk factor" with experiences of economic challenges during the pandemic. Fisher's Exact Tests were used to assess statistical significance. Adjusted logistic regression models were also conducted that controlled for sociodemographic characteristics, for time elapsed since the start of the pandemic, and for pre-pandemic income, homelessness, and injection frequency. Over half of our sample reported using alone more than usual during the pandemic, and over 40% reported using more than usual and/or buying drugs that were of a decreased purity or quality. Additionally, a large proportion of our sample (52.5% of those asked) reported more difficulty than usual accessing mental health care. Experiencing loss of a source of income during the pandemic was associated with using more drugs, using alone more, using a larger amount of drugs while using alone, wanting to stop using but being unable, and difficulty accessing mental health care. The preliminary associations found by the present study suggest that economic challenges or disruptions experienced during the pandemic are likely to increase risk for overdose among PWID experiencing such challenges, via changes in the above behaviors and/or conditions that are associated with risk for overdose. Intervention efforts should therefore be focused not only directly on overdose prevention, but also on assisting PWID with their economic challenges and helping them regain economic stability and access to services that may have been impeded by financial difficulty.

description: Limited archaeological rescue excavation was carried out to determine whether the manor's origins could be dated to the Late Saxon period. A stratified sequence was recovered indicating a succession, though not necessarily continuous, of phases of occupation and/or activity on the site from the first century AD onwards. The remains of Late Iron Age/early RB pits were discovered together with evidence for cultivation in the late Roman to Early-Mid Saxon periods. Part of a possible post-in-trench structure of Late Saxon date and a large recut ditch of Late Saxon/Norman date were also present, while the footings of a substantial stone wall of medieval or post-medieval date could represent the precursor of the present north-western boundary of the Manor.

description: L’appui pédagogique est souvent vu comme un bon moyen pour aider les élèves en difficulté ou présentant un retard prononcé, que ce soit par incompréhension du savoir traité ou suite à l’arrivée dans une nouvelle classe. Ayant vécu plusieurs méthodes d’appuis durant nos stages, nous avons décidé, durant notre 4ème semestre à la HEP, de nous pencher un peu plus sur la réelle utilité des appuis et leurs bienfaits, d’autant plus qu’ils sont obligatoires depuis l’introduction de la LEO(2011). Suite à quelques discussions et à certaines lectures, nous nous sommes vite rendu compte que les spécialistes pédagogiques n’étaient pas toujours favorables aux appuis tels qu’ils sont menés dans le canton de Vaud. En pointant l’effet de mise à l’écart que peut avoir l’appui sur les enfants ou l’accentuation des difficultés que ceux-ci ont dans leurs apprentissages, certaines études nous ont amenés à nous questionner sur les raisons d’une telle différence entre le but des appuis et ce que l’on constate sur le terrain. En prenant nos marques sur un travail de mémoire rédigé par Mélissa Bonjour et Sophie Poza en 2011, nous avons décidé de chercher les corrélations qu’il pouvait y avoir entre les représentations que se font les enseignantes des appuis, leurs influences sur la manière de collaborer ainsi que sur l’efficacité des appuis. Pour mener cette recherche, nous avons travaillé avec nos praticiennes formatrices ainsi que les enseignantes d’appui présentes lors de notre stage du 5ème semestre. En mettant en place un questionnaire construit sur les axes importants de notre mémoire (la collaboration, les représentations et les bénéfices des appuis), nous avons pu analyser la situation telle qu’elle est dans une classe multi-âges de 3ème - 4ème et une classe de 5ème HarmoS.

description: Ce mémoire vise à établir si les relations que les enseignants entretiennent avec leurs collègues ont une influence sur le risque de tomber en burnout. Quarante enseignants ont répondu à un questionnaire composé de trois parties : une série de questions personnelles d’ordre général ; puis une partie sur les relations sociales divisées en trois dimensions : intégration à la salle des maîtres, relations d’ordre professionnel et relations d’ordre personnel. La dernière partie est constituée par le test Maslach Burnout Inventory (Christina Maslach, 1981), où le burnout se traduit par l’épuisement émotionnel, la dépersonnalisation des relations et/ou la diminution du sentiment d’accomplissement personnel. Les résultats montrent que le facteur le plus influent est la qualité de la collaboration professionnelle de manière générale. Un bon esprit de collaboration favorise l’investissement affectif des enseignants dans leurs relations et les protège de la dépersonnalisation. Le sentiment d’être reconnu et valorisé par ses collègues joue un rôle particulier dans le niveau d’épuisement émotionnel ressenti par l’enseignant. D’autre part, les enseignants qui sont ouverts aux échanges de matériel ont peu tendance à dépersonnaliser leurs relations et bénéficient d’un meilleur sentiment d’accomplissement personnel. Discuter de travail avec ses collègues dans le cadre de sa vie privée présente un risque de s’épuiser émotionnellement. Enfin, dans une moindre mesure, lorsqu’un enseignant se trouve dans une situation relationnelle difficile, le fait de demander du soutien à ses collègues l’aide à ne pas se bloquer affectivement face à cette situation. Notre recherche met encore en évidence le rôle inévitable des facteurs personnels dans le risque de tomber en burnout, ainsi que l’importance de pouvoir faire ses propres choix et collaborer de façon autonome et spontanée avec ses collègues. L’enseignement est ainsi une profession plutôt individualiste, pour laquelle la qualité des relations entretenues avec les collègues constitue un facteur d’influence sur le risque de burnout.

description: As part of the Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) we report the discovery of a pair of faint dwarf galaxies (CenA-MM-Dw1 and CenA-MM-Dw2) at a projected distance of $\sim$90 kpc from the nearby elliptical galaxy NGC5128 (CenA). We measure a tip of the red giant branch distance to each dwarf, finding $D=3.63 \pm 0.41$ Mpc for CenA-MM-Dw1 and $D=3.60 \pm 0.41$ Mpc for CenA-MM-Dw2, both of which are consistent with the distance to NGC5128. A qualitative analysis of the color magnitude diagrams indicates stellar populations consisting of an old, metal-poor red giant branch ($\gtrsim 12$ Gyr, [Fe/H]$\sim-1.7$ to -1.9). In addition, CenA-MM-Dw1 seems to host an intermediate-age population as indicated by its candidate asymptotic giant branch stars. The derived luminosities ($M_V=-10.9\pm0.3$ for CenA-MM-Dw1 and $-8.4\pm0.6$ for CenA-MM-Dw2) and half-light radii ($r_{h}=1.4\pm0.04$ kpc for CenA-MM-Dw1 and $0.36\pm0.08$ kpc for CenA-MM-Dw2) are consistent with those of Local Group dwarfs. CenA-MM-Dw1's low central surface brightness ($μ_{V,0}=27.3\pm0.1$ mag/arcsec$^2$) places it among the faintest and most extended M31 satellites. Most intriguingly, CenA-MM-Dw1 and CenA-MM-Dw2 have a projected separation of only 3 arcmin ($\sim3$ kpc): we are possibly observing the first, faint satellite of a satellite in an external group of galaxies.

Life on a medieval backstreet: archaeological excavations at Swan Street, Northampton, 1989

description: Northamptonshire Archaeology, 25, 127-158
description: Excavations demonstrated the changing use of an area of land behind a minor street within the medieval walled town of Northampton. Such marginal sites are valuable in that they often prove to be more sensitive to the ebb and flow of a town's economic fortunes than the more intensively occupied major street frontages. Settlement appears to have spread into the area soon after the Norman Conquest and there may have been timber structures on the site from the mid-twelfth century. A hiatus in occupation occurred in the fourteenth century when the area appears to have been given over to cultivation, probably gardening. A horse burial from this period is of interest in bearing a large number of knife marks which suggest that flesh had been removed from the skeleton. This may have been for human consumption, although the feeding of dogs is equally likely. Further evidence of structures may attest to the return of settlement in the fifteenth century but by the sixteenth century the area was given over to cultivation once more. Possible bedding trenches again suggest gardening. The map evidence demonstrates that the area was used as orchards from the mid-eighteenth century until the early-nineteenth century when terraced buildings were constructed.
title: Jerzy Grotowski's influence on British theatre 1966-1980 : histories, perspectives, recollections
Creators: name: Pakula, Pablo
Publisher: name: University of Kent
Year: 2023

description: This thesis investigates Jerzy Grotowski's influence on British theatre from a historical point of view. It examines a series of telling case studies between 1966 and 1980 which represent instances of both direct and indirect connections with the Teatr Laboratorium, and which exemplify how Grotowski's practice/ideas have been adapted, borrowed, misunderstood, and used as a catalyst by different British theatre artists. These case studies include: Peter Brook's production of US with the Royal Shakespeare Company, the work of 'fringe' groups Freehold and Triple Action Theatre, and a number of individuals who participated in paratheatrical activities (Anna Furse, [ennifer Kumiega, etc.). In order to better assess the UK's relationship with Grotowski, this thesis also analyses the British response to his company's performances in 1968 and 1969, as well as discussing Towards a Poor Theatre as the primary channel for the dissemination of his ideas. This thesis concludes by proposing an alternative way of mapping Grotowski's influence, not in a linear or hierarchical manner, but using a model which foregrounds diversity and simultaneity. In doing so it emphasises the multiplicity of Grotowski's legacies and embraces the complex processes by which they have spread. The connections between Grotowski and the UK and the British relationship to his practice have not previously been scrutinised. Therefore the methodology adopted by the thesis is based on archival research, field work, and extensive interviews with key individuals.

description: We study theoretically the Raman scattering response $I(ω)$ in the gapless quantum spin liquid phase of the Kitaev-Heisenberg model. The dominant polarization-independent contribution $I_K (ω)$ reflects the density of states of the emergent Majorana fermions in the ground-state flux-sector. The integrability-breaking Heisenberg exchange generates a second contribution, whose dominant part $I_H (ω)$ has the form of a quantum quench corresponding to an abrupt insertion of four $Z_2$ gauge fluxes. This results in a weakly polarization dependent response with a sharp peak at the energy of the flux excitation accompanied by broad features, which can be related to Majorana fermions in the presence of the perturbed gauge field. We discuss the experimental situation and explore more generally the influence of integrability breaking for Kitaev spin liquid response functions.

description: Interlayer space in graphite is impermeable to ions and molecules, including protons. Its controlled expansion would find several applications in desalination, gas purification, high-density batteries, etc. In the past, metal intercalation has been used to modify graphitic interlayer spaces; however, resultant intercalation compounds are unstable in water. Here, we successfully expanded graphite interlayer spaces by intercalating aqueous KCl ions electrochemically. Our spectroscopy studies provide clear evidence for cation-π interactions explaining the stability of the devices, though weak anion-π interactions were also detectable. The water conductivity shows several orders of enhancement when compared to unintercalated graphite. Water evaporation experiments further confirm the high permeation rate. There is weak ion permeation through interlayer spaces, up to the highest chloride concentration of 1 M, an indication of sterically limited transport. In these very few transported ions, we observe hydration energy-dependent selectivity between salt ions. These strongly suggest a soft ball model of steric exclusion, which is rarely reported. These findings improve our understanding of molecular and ionic transport at the atomic scale.

description: We consider the thermal production of dileptons and photons at temperatures above the critical temperature in QCD. We use a model where color excitations are suppressed by a small value of the Polyakov loop, the semi Quark-Gluon Plasma (QGP). Comparing the semi-QGP to the perturbative QGP, we find a mild enhancement of thermal dileptons. In contrast, to leading logarithmic order in weak coupling there are far fewer hard photons from the semi-QGP than the usual QGP. To illustrate the possible effects on photon and dileptons production in heavy ion collisions, we integrate the rate with a realistic hydrodynamic simulation. Dileptons uniformly exhibit a small flow, but the strong suppression of photons in the semi-QGP tends to bias the elliptical flow of photons to that generated in the hadronic phase.

description: The quantitative assessment of the entanglement in multipartite quantum states is, apart from its fundamental importance, a practical problem. Recently there has been significant progress in developing new methods to determine certain entanglement measures. In particular, there is a method-in principle, analytical-to compute a certified lower bound for the three-tangle. The purpose of this work is to provide a manual for the implementation of this approach and to explicitly discuss several analytically solvable cases in order to gauge the numerical tools. Moreover, we derive a simple analytical bound for the mixed-state three-tangle.
Flow past a sphere translating along the axis of a rotating fluid: Revisiting numerically Maxworthy's experiments

description: We compute the flow induced by the steady translation of a rigid sphere along the axis of a large cylindrical container filled with a low-viscosity fluid set in rigid-body rotation, the sphere being constrained to spin at the same rate as the undisturbed fluid. The parameter range covered by the simulations is similar to that explored experimentally by Maxworthy [\textit{J. Fluid Mech.}, vol. 40, pp. 453-479 (1970)]. We describe the salient features of the flow, especially the internal characteristics of the Taylor columns that form ahead of and behind the body and the inertial wave pattern, and determine the drag and torque acting on the sphere. Torque variations are found to obey two markedly different laws under rapid- and slow-rotation conditions, respectively. The corresponding scaling laws are predicted by examining the dominant balances governing the axial vorticity distribution in the body vicinity. Results for the drag agree well with the semi-empirical law proposed for inertialess regimes by Tanzosh \& Stone [\textit{J. Fluid Mech.}, vol. 275, pp. 225-256 (1994)]. This law is found to apply even in regimes where inertial effects are large, provided rotation effects are also large enough. Influence of axial confinement is shown to increase dramatically the drag in rapidly rotating configurations, and the container length has to be approximately a thousand times larger than the sphere for this influence to become negligibly small. The reported simulations establish that this confinement effect is at the origin of the long-standing discrepancy existing between Maxworthy's results and theoretical predictions.

description: We present an unsupervised outlier detection method for galaxy spectra based on the spectrum autoencoder architecture spender, which reliably captures spectral features and provides highly realistic reconstructions for SDSS galaxy spectra. We interpret the sample density in the autoencoder latent space as a probability distribution, and identify outliers as low-probability objects with a normalizing flow. However, we found that the latent-space position is not, as expected from the architecture, redshift invariant, which introduces stochasticity into the latent space and the outlier detection method. We solve this problem by adding two novel loss terms during training, which explicitly link latent-space distances to data-space distances, preserving locality in the autoencoding process. Minimizing the additional losses leads to a redshift-invariant, non-degenerate latent space distribution with clear separations between common and anomalous data. We inspect the spectra with the lowest probability and find them to include blends with foreground stars, extremely reddened galaxies, galaxy pairs and triples, and stars that are misclassified as galaxies. We release the newly trained spender model and the latent-space probability for the entire SDSS-I galaxy sample to aid further investigations.

description: We derive level-rank duality in pure Chern-Simons gauge theories from a non-supersymmetric Seiberg duality by using a non-supersymmetric brane configuration in type IIB string theory. The brane configuration consists of fivebranes, N D3 antibranes and an O3 plane. By swapping the fivebranes we derive a 3d non-supersymmetric Seiberg duality. After level shifts from loop effects, this identifies the IR of Sp(2N)_{2k-2N+2} and Sp(2k-2N+2)_{-2N} pure Chern-Simons theories, which is a level-rank pair. We also derive level-rank duality in a Chern-Simons theory based on a unitary group.

Partant du principe que les enseignants titulaires sont des acteurs centraux dans les interventions auprès des élèves en échec scolaire, ce travail s’appuie sur des entretiens menés auprès de ces derniers. Les discours de ces professionnels sont analysés par thématique puis discutés transversalement. Les réflexions qui sont exprimées sont mises en lien avec des concepts comme la place de l’élève en difficulté, son rapport au reste du groupe, des approches décontextualisées (exemple de la métacognition), les risques encourus par les enseignants ou les possibilités d’incohérences des mesures d’aide périphériques. Le matériel récolté dans cette expérience nourrira le développement de la structure de prise en charge intégrée des élèves en difficulté de l’établissement observé et pourra également enrichir les conceptions ou les évolutions d’autres systèmes similaires d’accompagnement. C’est une démarche qui s’inscrit sur une réalité, une structure établie dans une culture d’établissement. Les singularités de ce terrain seront à la fois la force et la limite de cette recherche. Nous nous positionnons sur un dispositif concret qui offrira des possibilités d’analyse et de réflexion sur les moyens d’aider les élèves qui ont décroché. Les résultats obtenus, avec la distance qu’imposent les choix méthodologiques, permettent de constater l’importance pour les enseignants de l’homogénéité des rythmes d’apprentissage ou de l’atteinte des objectif. Ces derniers recherchent activement des solutions pour débloquer les situations ou des stratégies d’apprentissage qui seront efficaces pour leurs élèves en difficulté. Ils valorisent la collaboration, tout en reconnaissant parfois éprouver des difficultés à la maintenir.

description: Motivated by recent experiments, we study the properties of large Bose-Hubbard chains with single-particle losses at one site using classical field methods. We construct and validate a compact effective model that reduces computations to only a few sites. We show that in the mean-field approach the description captures the stationary states of the dissipative mode very well. Not only is there a good quantitative agreement in the hysteresis loop, the dark soliton state can be reproduced as well due to the the preservation of the $U(1)$ symmetry. Bimodality of the steady states, observed on longer timescales, is studied using the truncated Wigner method. We compare the switching statistics and derive the effective Liouvillian gap in function of the tunneling, showing that the effective description underestimates fluctuations.

description: The most massive stars on the asymptotic giant branch (AGB), so called super-AGB stars, are thought to produce supernovae (SNe) triggered by electron captures in their degenerate O+Ne+Mg cores. Super-AGB stars are expected to have slow winds with high mass-loss rates, so their wind density is high. The explosions of super-AGB stars are therefore presumed to occur in this dense wind. We provide the first synthetic light curves (LCs) for such events by exploding realistic electron-capture supernova (ecSN) progenitors within their super-AGB winds. We find that the early LC, i.e. before the recombination wave reaches the bottom of the H-rich envelope of SN ejecta (the plateau phase), is not affected by the dense wind. However, after the plateau phase, the luminosity remains higher when the super-AGB wind is taken into account. We compare our results to the historical LC of SN 1054, the progenitor of the Crab Nebula, and show that the explosion of an ecSN within an ordinary super-AGB wind can explain the LC features. We conclude that SN 1054 could have been a Type IIn SN without any extra extreme mass loss which was previously suggested to be necessary to account for its early high luminosity. We also show that our LCs match Type IIn SNe with an early plateau phase (`Type IIn-P') and suggest that they are ecSNe within super-AGB winds. Although some ecSNe can be bright in the optical spectral range due to the large progenitor radius, their X-ray luminosity from the interaction does not necessarily get as bright as other Type IIn SNe whose optical luminosities are also powered by the interaction. Thus, we suggest that optically-bright X-ray-faint Type IIn SNe can emerge from ecSNe. Optically-faint Type IIn SNe, such as SN 2008S, can also originate from ecSNe if their H-rich envelope masses are small. Some of them can be observed as `Type IIn-b' SNe due to the small H-rich envelope mass.

description: Topological defects and smooth excitations determine the properties of systems showing collective order. We introduce a generic non-singular field theory that comprehensively describes defects and excitations in systems with $O(n)$ broken rotational symmetry. Within this formalism, we explore fast events, such as defect nucleation/annihilation and dynamical phase transitions where the interplay between topological defects and non-linear excitations is particularly important. To highlight its versatility, we apply this formalism in the context of Bose-Einstein condensates, active nematics, and crystal lattices.

description: Το δίκαιο της ποινικής εκτέλεσης αποτελείται από κανόνες που ακολουθούν την ποινική διαδικασία από το αμετάκλητο της απόφασης μέχρι την έκτιση της ποινής. Στο πεδίο της εκτέλεσης της ποινής, είναι ιδιαίτερα σημαντική η δικονομική δυνατότητα του καταδικασθέντος να αμφισβητήσει τη νομιμότητα της ποινικής εκτέλεσης. Το άρθρο 562 του Κώδικα Ποινικής Δικονομίας, το οποίο αποτελεί το θέμα της παρούσας εργασίας, αναλύει τη διαδικασία των αντιρρήσεων κατά την εκτέλεση της απόφασης. Η πρώτη ενότητα παρουσιάζει μια ιστορική διαδρομή των τροποποιήσεων που η εν λόγω διάταξη έχει υποστεί. Ακολούθως, η όλη διαδικασία, καθώς και οι περιπτώσεις που το άρθρο 562 του Κώδικα Ποινικής Δικονομίας μπορεί να εφαρμοστεί παρουσιάζονται λεπτομερώς στις ενότητες 2-3, με έμφαση σε εκείνες που σχετίζονται με τη διάρκεια της εκτελεστής ποινής. Η τέταρτη ενότητα ασχολείται με τις αντιρρήσεις στην εκτέλεση της απόφασης σε συνδυασμό με την απόλυση υπό όρους και την αναστολή εκτέλεσης. Εν κατακλείδι, διατυπώνονται μερικές σκέψεις για την αναγκαιότητα της διαδικασίας αυτής ως δικλείδα ασφαλείας του καταδικασθέντος για την ορθή απονομή δικαιοσύνης κατά το στάδιο της εκτέλεσης των αποφάσεων.
description: The law of criminal enforcement consists of rules that follow the criminal proceedings during the irrevocable judgement up to the completion of the sentence. In the area of executing the sentence, it is of great importance for the procedural ability of the convicted person to contest the legality of the criminal enforcement. Article 562 of the Criminal Procedure Code, which is the subject of this academic paper, analyses the procedure of objections to the enforcement of judgement. Section 1 presents a historical review of the amendments that the provision at issue has been subject to. Following that, the whole procedure, as well as the cases that Article 562 of the Criminal Procedure Code can be applied to are presented in detail in sections 2-3 with emphasis on those concerning the duration of the enforceable sentence. Section Four deals with objections to the enforcement of the judgement in conjunction with conditional dismissal and conditional discharge. In the end, there are some thoughts on the necessity of this procedure as a safeguard for the convicted person for the proper administration of justice during the enforcement of the judgements.
Entanglement swapping with energy-polarization entangled photons from quantum dot cascade decay

description: We theoretically investigate the efficiency of an entanglement swapping procedure based on the use of quantum dots as sources of entangled photon pairs. The four-photon interference that affects such efficiency is potentially limited by the fine-structure splitting and by the time correlation between cascaded photons, which provide which-path information. The effect of spectral inhomogeneity is also considered, and a possible quantum eraser experiment is discussed for the case of identical dots.
Characteristics of fluid-fluid displacement in model mixed-wet porous media: patterns, pressures, and scalings

description: We study the characteristics of fluid-fluid displacement in simple mixed-wet porous micromodels numerically using a dynamic pore network model. The porous micromodel consists of distinct water-wet and oil-wet regions, whose fractions are systematically varied to yield a variety of displacement patterns over a wide range of capillary numbers. We find that the impact of mixed-wettability is most prominent at low capillary number, and it depends on the complex interplay between wettability fraction and the intrinsic contact angle of the water-wet regions. For example, the fractal dimension of the displacement pattern is a monotonically increasing function of wettability fraction in flow cells with strongly water-wet clusters, but it becomes non-monotonic with respect to wettability fraction in flow cells with weakly water-wet clusters. Additionally, mixed-wettability also manifests itself in the injection-pressure signature, which exhibits fluctuations especially at low wettability fraction. Specifically, preferential filling of water-wet regions leads to reduced effective permeability and higher injection pressure, even at vanishingly small capillary numbers. Finally, we demonstrate that scaling analyses based on a weighted average description of the overall wetting state of the mixed-wet system can effectively capture the variations in observed displacement pattern morphology.

description: Cette recherche porte sur l’analyse de deux études de cas uniques de type qualitative. L’étude articule l’intervention de Pédagogues en Education Précoce Spécialisée (PEPS) dans le cadre du Service Educatif Itinérant (SEI) avec une adaptation de la méthode d’observation attentive selon Esther Bick (Tavistock Clinic). Elle veut investiguer les apports que la méthode peut amener aux séances SEI, si elle peut être utilisée comme outil au service de la PEPS et quels bénéfices peuvent être retirés (pour la PEPS, l’enfant et les parents). Les retranscriptions des observations ont fait l’objet d’une analyse des données selon la méthode de la grounded theory. Les résultats démontrent que l’observation Bick-Tavistock contribue à former la PEPS en développant des compétences importantes lui permettant de mieux comprendre les états internes des enfants. La méthode est également utile aux parents qui s’identifient à la fonction observante et aux enfants, leur permettant de se doter d’un appareil à penser.

Quark mass hierarchies and CP violation in $A_4\times A_4\times A_4$ modular symmetric flavor models

description: We study $A_4 \times A_4 \times A_4$ modular symmetric flavor models to realize quark mass hierarchies and mixing angles without fine-tuning. Mass matrices are written in terms of modular forms. At modular fixed points $τ= i\infty$ and $ω$, $A_4$ is broken to $Z_3$ residual symmetry. When the modulus $τ$ is deviated from the fixed points, modular forms show hierarchies depending on their residual charges. Thus, we obtain hierarchical structures in mass matrices. Since we begin with $A_4\times A_4 \times A_4$, the residual symmetry is $Z_3 \times Z_3 \times Z_3$ which can generate sufficient hierarchies to realize quark mass ratios and absolute values of the CKM matrix $|V_{\textrm{CKM}}|$ without fine-tuning. Furthermore, CP violation is studied. We present necessary conditions for CP violation caused by the value of $τ$. We also show possibilities to realize observed values of the Jarlskog invariant $J_{\textrm{CP}}$, quark mass ratios and CKM matrix $|V_{\textrm{CKM}}|$ simultaneously, if $\mathcal{O}(10)$ adjustments in coefficients of Yukawa couplings are allowed.
