description: We introduce a new class of $\mathcal{PT}$-symmetric complex crystals which are almost transparent and one-way reflectionless over a broad frequency range around the Bragg frequency, i.e. unidirectionally invisible, regardless of the thickness $L$ of the crystal. The $\mathcal{PT}$-symmetric complex crystal is synthesized by a supersymmetric transformation of an Hermitian square well potential, and exact analytical expressions of transmission and reflection coefficients are given. As $L$ is increased, the transmittance and reflectance from one side remain close to one and zero, respectively, whereas the reflectance from the other side secularly grows like $ \sim L^2$ owing to unidirectional Bragg scattering. This is a distinctive feature as compared to the previously studied case of the complex sinusoidal $\mathcal{PT}$-symmetric potential $V(x)=V_0 \exp(-2i k_ox)$ at the symmetry breaking point, where transparency breaks down as $L \rightarrow \infty$.

description: Problématique : Le rôle de la sage-femme est centré sur la promotion de la physiologie. Dans un contexte de médicalisation de la naissance, sa pratique contemporaine en obstétrique comporte des défis en lien avec la culture du risque. Ce travail de Bachelor, adopte une vision des sciences sociales sur le risque. Il vise à interroger les influences de la culture du risque sur l’accompagnement de la naissance et sur le rôle des sages-femmes. Méthodologie : Cette revue de littérature a été réalisée par des recherches dans les bases de données Sociological Abstracts, PubMed, CINAHL et MIDIRS ainsi que des recherches par auteur. Nous avons ainsi sélectionné huit articles qualitatifs, une revue de littérature et une étude quantitative. Une analyse critique a été effectuée à l’aide de grilles d’analyse adaptées. Résultats et conclusion : L’omniprésence du risque dans la société contemporaine et en obstétrique, engendre des tensions entre la promotion de la physiologie et la surveillance des risques potentiels pour la mère et le nouveau-né. Des stratégies, parfois inconscientes, sont utilisées par les femmes, les couples et les sages-femmes pour assimiler, négocier ou résister au risque. Les conséquences de la culture du risque seront évoquées. L’imprégnation du risque dans les discours et les pratiques limite les possibilités de définir la physiologie de la naissance et de son accompagnement, appelant à une posture réflexive et non naïve des sages-femmes.

description: Objectifs Depuis plusieurs décennies, la médicalisation de la naissance est très présente en milieu hospitalier. Toutefois elle n’est pas toujours justifiée. Ce Travail de Bachelor a pour but de proposer des stratégies aux sages-femmes pour favoriser la physiologie de l’accouchement à l’hôpital. Méthodologie Pour la réalisation de ce travail, une revue de littérature a été effectuée dans différentes bases de données : PubMed, MIDIRS et CINHAL. Ces recherches ont permis une sélection de dix articles scientifiques, tous de type qualitatif, apportant des éléments de réponses à la problématique. Résultats et Conclusion La revue de littérature met en évidence des facteurs auxquels la sage-femme peut avoir recours pour promouvoir l'accouchement physiologique en milieu hospitalier. La philosophie de soins, la place et les rôles de la sage-femme ainsi que l’environnement de la naissance en sont les éléments clés. De nouvelles pistes de recherche pourraient permettre d’approfondir la réflexion et apporter davantage de moyens à la sage-femme dans sa pratique pour encourager la physiologie de la naissance.

description: Recent studies on Click-Through Rate (CTR) prediction has reached new levels by modeling longer user behavior sequences. Among others, the two-stage methods stand out as the state-of-the-art (SOTA) solution for industrial applications. The two-stage methods first train a retrieval model to truncate the long behavior sequence beforehand and then use the truncated sequences to train a CTR model. However, the retrieval model and the CTR model are trained separately. So the retrieved subsequences in the CTR model is inaccurate, which degrades the final performance. In this paper, we propose an end-to-end paradigm to model long behavior sequences, which is able to achieve superior performance along with remarkable cost-efficiency compared to existing models. Our contribution is three-fold: First, we propose a hashing-based efficient target attention (TA) network named ETA-Net to enable end-to-end user behavior retrieval based on low-cost bit-wise operations. The proposed ETA-Net can reduce the complexity of standard TA by orders of magnitude for sequential data modeling. Second, we propose a general system architecture as one viable solution to deploy ETA-Net on industrial systems. Particularly, ETA-Net has been deployed on the recommender system of Taobao, and brought 1.8% lift on CTR and 3.1% lift on Gross Merchandise Value (GMV) compared to the SOTA two-stage methods. Third, we conduct extensive experiments on both offline datasets and online A/B test. The results verify that the proposed model outperforms existing CTR models considerably, in terms of both CTR prediction performance and online cost-efficiency. ETA-Net now serves the main traffic of Taobao, delivering services to hundreds of millions of users towards billions of items every day.

description: We study the vortex dynamics and vortex pinning effect in Bose-Einstein condensate in a rotating double-well trap potential and co-rotating optical lattice. We show that, in agreement with the experiment, the vortex number do not diverge when the rotational frequency $Ω\rightarrow 1$ if the trap potential is of anisotropic double-well type. The critical rotational frequency as obtained from numerical simulations agrees very well with the value $\sqrt l/l$ for $l=4$ which supports the conjecture that surface modes with angular momentum $l=4$ are excited when the rotating condensate is trapped in double-well potential. The vortex lattice structure in a rotating triple-well trap potential and its pinning shows very interesting features. We show the existence and pinning of a new type of hidden vortices whose phase profile is similar to that of the visible vortices.

description: Recent theoretical studies predict that the circumgalactic medium (CGM) around low-redshift, $\sim L_*$ galaxies could have substantial nonthermal pressure support in the form of cosmic rays. However, these predictions are sensitive to the specific model of cosmic-ray transport employed, which is theoretically and observationally underconstrained. In this work, we propose a novel observational constraint for calculating the lower limit of the radially-averaged, effective cosmic-ray transport rate, $κ_{\rm min}^{\rm eff}$. Under a wide range of assumptions (so long as cosmic rays do not lose a significant fraction of their energy in the galactic disk, regardless of whether the cosmic-ray pressure is important or not in the CGM), we demonstrate a well-defined relationship between $κ_{\rm min}^{\rm eff}$ and three observable galaxy properties: the total hydrogen column density, the average star formation rate, and the gas circular velocity. We use a suite of FIRE-2 galaxy simulations with a variety of cosmic-ray transport physics to demonstrate that our analytic model of $κ_{\rm min}^{\rm eff}$ is a robust lower limit of the true cosmic-ray transport rate. We then apply our new model to calculate $κ_{\rm min}^{\rm eff}$ for galaxies in the COS-Halos sample, and confirm this already reveals strong evidence for an effective transport rate which rises rapidly away from the interstellar medium to values $κ_{\rm min}^{\rm eff}\gtrsim 10^{30-31}\,{\rm cm}^2\,{\rm s}^{-1}$ (corresponding to anisotropic streaming velocities of $v^{\rm stream}_{\rm eff} \gtrsim 1000\,{\rm km}\,{\rm s}^{-1}$) in the diffuse CGM, at impact parameters larger than $50-100$\,kpc. We discuss how future observations can provide qualitatively new constraints in our understanding of cosmic rays in the CGM and intergalactic medium.

Actuellement, l’acupuncture est une médecine alternative qui s’est démocratisée ces dernières années et qui serait une méthode de choix pour soulager les nausées et les vomissements ainsi que d’autres maux de grossesse. Objectif : identifier l’efficacité de l’acupuncture pour diminuer les nausées et vomissements durant la grossesse. Méthode : une revue de littérature a été réalisée à partir de dix articles scientifiques. Ils ont été sélectionnés pour leur pertinence quant à la thématique, sur trois bases de données, PubMed, MIDIRS et CINHAL. Résultats : une efficacité de l’acupuncture a été démontrée dans la réduction des nausées et vomissements. Dans les études présentées, des résultats significatifs sont venus appuyer cette constatation. D’autres impacts positifs de l’acupuncture sur la femme enceinte ont pu être soulignés. De plus, aucun effet secondaire sur l’issue de la grossesse et du foetus n’a été relevé après l’utilisation de cette médecine. Conclusion : l’acupuncture peut être recommandée aux femmes enceintes de manière sécuritaire. Suite à ces résultats, les sages-femmes pourraient proposer cette méthode de façon plus systématique, en réponse à une demande des femmes d’utiliser des méthodes non pharmacologiques.

description: Let $γ$ be a generic closed curve in the plane. Samuel Blank, in his 1967 Ph.D. thesis, determined if $γ$ is self-overlapping by geometrically constructing a combinatorial word from $γ$. More recently, Zipei Nie, in an unpublished manuscript, computed the minimum homotopy area of $γ$ by constructing a combinatorial word algebraically. We provide a unified framework for working with both words and determine the settings under which Blank's word and Nie's word are equivalent. Using this equivalence, we give a new geometric proof for the correctness of Nie's algorithm. Unlike previous work, our proof is constructive which allows us to naturally compute the actual homotopy that realizes the minimum area. Furthermore, we contribute to the theory of self-overlapping curves by providing the first polynomial-time algorithm to compute a self-overlapping decomposition of any closed curve $γ$ with minimum area.

description: Objectif : Le stress est fortement documenté dans la littérature scientifique. Beaucoup d’études évaluent son impact pendant la grossesse sur l’enfant à venir et sur l’issue obstétricale. Toutefois, les connaissances et pratiques sont peu stabilisées. L’espoir de ce travail repose sur la possibilité de prévenir ou diminuer le stress prénatal dans la pratique quotidienne puisqu’il est reconnu comme un problème de santé publique. Méthodologie : Cette recherche a été réalisée grâce aux bases de données Pubmed, Midirs et Cinhal. Elle concerne les interventions professionnelles pour prendre en compte le stress des femmes enceintes. Neuf études ont été analysées avec des grilles spécifiques de lecture : deux revues systématiques, trois essais contrôlés randomisés, deux études transversales et une étude qualitative. L’ensemble du corpus a ensuite été synthétisé pour en extraire les résultats. Résultats : Deux axes découlent de l’analyse : les interventions pour réduire les symptômes de stress (relaxation) et la prise en compte des potentiels stresseurs (facteurs psycho-sociaux). Il n’y a ni recommandations précises ni consensus pour dépister, prévenir et traiter le stress. Cependant, en connaître les causes et traiter les femmes à risque se révélerait utile pour promouvoir leur santé et l’issue obstétricale. Discussion : Les études analysées expliquent que le stress prénatal reste un sujet novateur et qu’en l’absence d’essais à larges échantillons, peu d’indications précises pour les soins peuvent être conseillées. Néanmoins, ce travail propose quelques pistes réflexives pour la pratique sage-femme en Suisse en regard des données probantes en collaboration avec les professionnels de la périnatalité.

description: Cold start is an essential and persistent problem in recommender systems. State-of-the-art solutions rely on training hybrid models for both cold-start and existing users/items, based on the auxiliary information. Such a hybrid model would compromise the performance of existing users/items, which might make these solutions not applicable in real-worlds recommender systems where the experience of existing users/items must be guaranteed. Meanwhile, graph neural networks (GNNs) have been demonstrated to perform effectively warm (non-cold-start) recommendations. However, they have never been applied to handle the cold-start problem in a user-item bipartite graph. This is a challenging but rewarding task since cold-start users/items do not have links. Besides, it is nontrivial to design an appropriate GNN to conduct cold-start recommendations while maintaining the performance for existing users/items. To bridge the gap, we propose a tailored GNN-based framework (GPatch) that contains two separate but correlated components. First, an efficient GNN architecture -- GWarmer, is designed to model the warm users/items. Second, we construct correlated Patching Networks to simulate and patch GWarmer by conducting cold-start recommendations. Experiments on benchmark and large-scale commercial datasets demonstrate that GPatch is significantly superior in providing recommendations for both existing and cold-start users/items.

description: Contexte Généralement, la plupart des femmes consulte un professionnel de santé entre huit et douze semaines de grossesse [traduction libre] (Health Council of the Netherlands, 2007, p.18). Cependant, comme les organes foetaux sont déjà formés, il semble trop tard pour détecter les facteurs de risques préexistants et prévenir les éventuelles issues néfastes de grossesse [traduction libre] (Sadler, 2006, cité dans Atrash, Jack & Johnson, 2008, p.2). Il paraît alors judicieux d’offrir des soins préconceptionnels [SP] avant le début d’une grossesse. Objectifs Cette revue de littérature vise à identifier l’impact des SP sur les connaissances et changements de comportements préconceptionnels de santé chez les couples en âge de procréer. Méthode A l’aide de descripteurs, une recherche a été entreprise sur les bases de données CINAHL et Medline-PubMed. Dix articles scientifiques ont été retenus et analysés. Résultats Les résultats ont été répertoriés en quatre catégories, soit l’impact des SP sur les connaissances et comportements des couples, l’avis des femmes et des professionnels, les différentes formes ainsi que les liens entre les SP et les issues de grossesse. Conclusion Bien que ce travail présente certaines idées pour implanter les SP dans les soins actuels, cette problématique reste complexe. Dans une perspective d’approfondissement, il pourrait être utile de mener des recherches ciblant les besoins spécifiques des femmes afin de pouvoir y adapter nos soins.

description: Deep learning methods have been shown to be effective for the automatic segmentation of structures and pathologies in medical imaging. However, they require large annotated datasets, whose manual segmentation is a tedious and time-consuming task, especially for large structures. We present a new method of partial annotations that uses a small set of consecutive annotated slices from each scan with an annotation effort that is equal to that of only few annotated cases. The training with partial annotations is performed by using only annotated blocks, incorporating information about slices outside the structure of interest and modifying a batch loss function to consider only the annotated slices. To facilitate training in a low data regime, we use a two-step optimization process. We tested the method with the popular soft Dice loss for the fetal body segmentation task in two MRI sequences, TRUFI and FIESTA, and compared full annotation regime to partial annotations with a similar annotation effort. For TRUFI data, the use of partial annotations yielded slightly better performance on average compared to full annotations with an increase in Dice score from 0.936 to 0.942, and a substantial decrease in Standard Deviations (STD) of Dice score by 22% and Average Symmetric Surface Distance (ASSD) by 15%. For the FIESTA sequence, partial annotations also yielded a decrease in STD of the Dice score and ASSD metrics by 27.5% and 33% respectively for in-distribution data, and a substantial improvement also in average performance on out-of-distribution data, increasing Dice score from 0.84 to 0.9 and decreasing ASSD from 7.46 to 4.01 mm. The two-step optimization process was helpful for partial annotations for both in-distribution and out-of-distribution data. The partial annotations method with the two-step optimizer is therefore recommended to improve segmentation performance under low data regime.

description: We have studied the electronic structure of CdS/ZnSe coupled quantum dot, a novel heterostructure at the nano-scale. Our calculations reveal CdS/ZnSe coupled quantum dots to be of type-II in nature where the anion-p states play an important role in deciding the band offset for the highest occupied molecular orbitals (HOMO). We show that the offsets of HOMO as well as the lowest unoccupied molecular orbitals (LUMO) can be tuned by changing the sizes of the components of the coupled quantum dot, thereby providing an additional control parameter to tune the band gap and the optical properties. Our investigations also suggest that formation of alloy near the interface has very little influence on the band offsets, although it affects the spatial localization of the quantum states from the individual components. Comparing the influence of strain on coupled quantum dots and core/shell nanowires, we find strain practically has no role in the electronic structure of coupled quantum dots as the small effective area of the interface in a coupled quantum dot helps a large part of the structure remain free from any substantial strain. We argue that in contrast to core-shell nanowires, quantum confinement is the key parameter that controls the electronic properties of coupled quantum dot and should therefore be an ideal candidate for the design of a quantum device.

What sets the splashback radius of dark matter haloes: accretion history or other properties?

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: The density profiles of dark matter haloes contain rich information about their growth history and physical properties. One particularly interesting region is the splashback radius, $R_{\rm sp}$, which marks the transition between particles orbiting in the halo and particles undergoing first infall. While the dependence of $R_{\rm sp}$ on the recent accretion rate is well established and theoretically expected, it is not clear exactly what parts of the accretion history $R_{\rm sp}$ responds to, and what other halo properties might additionally influence its position. We comprehensively investigate these questions by correlating the dynamically measured splashback radii of a large set of simulated haloes with their individual growth histories as well as their structural, dynamical, and environmental properties. We find that $R_{\rm sp}$ is sensitive to the accretion over one crossing time but largely insensitive to the prior history (in contrast to concentration, which probes earlier epochs). All secondary correlations are much weaker, but we discern a relatively higher $R_{\rm sp}$ in less massive, older, more elliptical, and more tidally deformed haloes. Despite these minor influences, we conclude that the splashback radius is a clean indicator of a halo's growth over the past dynamical time. We predict that the magnitude gap should be a promising observable indicator of a halo's accretion rate and splashback radius.

description: The work seeks to identify whether an intelligent system can be built ad hoc for the automatic and preventive capture of conflicts of interest in the context of Public Administrations that they carry out activities functional to health (health procurement). The legislation on public procurement (especially the health one), the one on “conflicts of interest”, on the protection of personal data and on transparency is explored, arriving at the doctrinal and jurisprudential reflections and perspectives on the relationship between P.A. and artificial intelligence. The writer, undoubtedly, retraces the path traced by the doctrine, arriving at a more compelling solution, i.e. promoting, on the same basis as the so-called “protective algorithm” (i.e. functional to the person and his protection), the notion of “preventive algorithm”, which must be imbued with legal values for the captative decision (ethics by design) and must be persistently imbued with these values until the its natural and material kept running (ethics by default). The primary nature and priority of the “humanization of the algorithm” and its “functionalization” to achieve the psycho-physical well-being of the person, but also that the effectiveness and efficiency of the PA is not hidden. Nor is the need to construct a notion of “ex ante merit screening” of any intelligent system. The work focuses on the doctrinal developments on the “subjective tripartition” of the responsibility of algorithms and elaborates a series of conclusive reflections, establishing that it is absolutely possible to be able to create a captative computer system, in compliance with the fundamental rights of the person, capable of bringing the PA to a rationalization of resources and above all to a legitimate achievement of the objectives. Finally, the work opens some arguments on the civil liability of health robots; on the possibility, through the informed consent collected by an inmate to be able to donate their neuronal data (with the limit of functionalization of the purpose – so-called neuronal privacy –) for study and research in the light of Law no. 10/2020 (on the subject of post mortem body donation for scientific research purposes) and on the possibility of managing one’s data (habeas data and habeas mentem) “now by then”.

Elle est le point essentiel permettant d’éviter la propagation des micro-organismes et par conséquent de limiter les infections liées aux infections associées aux soins. Les services de médecine nucléaire accueillent une grande diversité de patient ayant des pathologies et sensibilités différentes face aux micro-organismes. Le but de notre étude est premièrement de vérifier la présence ou l’absence de micro-organismes sur diverses surfaces dans le service de médecine nucléaire du Centre Hospitalier Universitaire Vaudois et d’évaluer l’efficacité du nettoyage établi par les protocoles du service. Matériel et méthode Nous avons réalisé des prélèvements sur des surfaces avant et après nettoyage, ainsi que des prélèvements de l’air ambiant, dans trois salles du service de médecine nucléaire. Des germes totaux, des staphylocoques, des bactéries à gram négatifs et des champignons ont été recherchés lors de ces prélèvements. Les surfaces étudiées sont touchées par le technicien en radiologie médicale ou en contact direct avec le patient lors de la réalisation de l’examen. Résultats Une contamination des surfaces proches de l’environnement du TRM a été mise en évidence. La présence sur une surface de staphylocoque doré ainsi que celle de champignon dans l’air a été relevée. Toutefois, la majorité des sites investigués présentaient un taux de contamination en deçà des recommandations en vigueur. Conclusion Des microorganismes potentiellement pathogènes ont été identifiés. Les principaux sites présentant une contamination supérieure aux recommandations sont ceux nettoyés hebdomadairement. Ceci suggère une modification des protocoles de nettoyage de ces sites.

description: Il presente studio esamina le possibili articola zioni della scrittura autobiografica contempora nea. Nello specifico si esegue una comparazione fra Una ragazza del secolo scorso (2005 e 2007) di Rossana Rossanda e Gli anni di Annie Ernaux (2008; trad. italiana 2015). In apparenza en trambe contraddistinte da una narrazione auto referenziale, le due opere si focalizzano su tre te matiche principali quali il ricordo, la costruzione progressiva (ma non evolutiva) di un’identità per sonale, e un piano anagogico (senso mistico) o della perpetuazione (memoria culturale) della storia di un’epoca. La forma scelta risulta deter minata da un concetto della scrittura del sé che, pur partendo dalla convinzione autoriale di pos sedere uno sguardo prospettico marcato dal fatto di “essere di sinistra”, presenta nondimeno delle radicali divergenze, questo alla luce del comune recupero ermeneutico del passato, considerato quale proprietà (fra le tante) della scrittura auto biografica.
description: The present study examines the possible articula tions of contemporary autobiographical writing. Specifically, a comparison is made between Ros sana Rossanda’s La ragazza del secolo scorso (2005 and 2007) and Annie Ernaux’s Gli anni (2008; Italian transl. 2015). Both characterized by a self-referential narrative, the two works fo cus on three main themes such as memory, the progressive (but not evolutionary) construction of a personal identity, and an anagogical level (mys tical sense) or perpetuation (cultural memory) of the history of an era. The chosen form is deter mined by a concept of the writing of the self which, although starting from the authorial conviction of possessing a perspective gaze marked by the fact of “being left-wing”, nevertheless presents radical divergences in content as in form this despite a shared sense of the relevance of hermeneutic re covery of the past, considered as a property (among many) of autobiographical writing.

description: En radiologie forensique, les projectiles provoquent des artéfacts sur les images de tomodensitométrie. Les deux principaux artéfacts qui nous intéressent pour cette étude sont l’artéfact métallique et l’artéfact de durcissement de faisceau. Ces derniers empêchent une lecture de clichés aisée dans la mesure où la visualisation du projectile ainsi que des tissus mous est parasitée. Ce travail vise à déterminer quels paramètres d’acquisition et de post-traitement d’image permettent d’optimiser la lecture de clichés. Il compare en particulier deux protocoles contenant des méthodes de reconstructions différentes, à savoir, la rétroprojection filtrée et l’algorithme itératif ASIR. Des images ont été acquises avec le scanner du centre universitaire romand de médecine légale à Lausanne (CURML). Le centre de physique et balistique forensique de l’institut de médecine légale de l’université de Berne nous a fournis quatre blocs de savon balistique contenant différents projectiles : l’Action 4, le Winchester 308, le GP11 et le GP90. Après différents traitements d’images, les clichés obtenus ont été évalués via un questionnaire par le personnel de médecine légale du CURML et un inspecteur de police. Les résultats ont montré que le protocole avec une méthode de reconstruction par rétroprojection filtrée favorise la visualisation des contours des différents projectiles ainsi que celle des tissus mous. L’échantillon était restreint, mais spécifique. Ainsi, bien que les résultats ne puissent pas être significatifs, nous pouvons donner une orientation plus précise quant aux paramètres techniques à utiliser pour optimiser la visualisation d’un projectile en médecine légale lors de cas réels.

description: L’objectif de cette étude est d’investiguer l’effet du rayonnement diffusé sur la résolution spatiale en radiodiagnostic, sur un appareil numérique à conversion directe. Nous avons imagé des plaques de poly méthacrylate de méthyle selon la méthode du beam-stop pour quantifier le rayonnement diffusé au travers du rapport S/P. Les paramètres d’acquisition ont été choisis de manière à se rapprocher des conditions cliniques. La tension, l’épaisseur et la taille de champ sont les trois paramètres que nous avons fait varier pour ces mesures. La résolution spatiale a été évaluée dans des conditions identiques à l’aide d’une mire de résolution. D’après notre étude, la tension n’a pas d’influence sur le rapport S/P (écart relatif à la moyenne toujours inférieur ou égal à 10%). Par contre, le rapport S/P augmente avec la taille de champ et l’épaisseur (facteur 6 entre 5 et 25cm, avec champ de 15cm*15cm). La résolution spatiale est influencée par les trois paramètres. L’influence de la tension et de la taille de champ est plus marquée lorsque l’épaisseur de matière augmente. En corrélant les résultats de ces deux études, nous observons que plus le rapport S/P augmente, plus la résolution spatiale diminue. En conclusion, il est essentiel d’optimiser la taille de champ et de diminuer l’épaisseur de la structure explorée pour réduire le diffusé mais également pour améliorer la résolution spatiale. De plus, notre étude du rapport S/P nous permet d’estimer le rapport S/P pour toutes les tailles de champ (268 à 1600 cm2) et épaisseurs (5 à 25 cm).

description: Quantum Gaussian states can be considered as the majority of the practical quantum states used in quantum communications and more generally in quantum information. Here we consider their properties in relation with the geometrically uniform symmetry, a property of quantum states that greatly simplifies the derivation of the optimal decision by means of the square root measurements. In a general framework of the $N$-mode Gaussian states we show the general properties of this symmetry and the application of the optimal quantum measurements. An application example is presented, to quantum communication systems employing pulse position modulation. We prove that the geometrically uniform symmetry can be applied to the general class of multimode Gaussian states.

description: We would like to comment on a recent paper by Sturrock et al. [1] in which the authors analyze decay data acquired by an ionization chamber in our institute. They interpret the variations in the data as solar-driven changes in the decay rates of the radionuclides under study. In brief we would like to discuss and elucidate the properties and the origin of the data used by the authors and explain why these data are not a sound basis for claiming evidence for new physics.

description: We consider the entanglement island in a deformed Jackiw-Teitelboim black hole in the presence of the phase transition. This black hole has the van der Waals-Maxwell-like phase structure as it is coupled with a Maxwell field. We study the behavior of the Page curve of this black hole by using the island paradigm. In the fixed charge ensemble, we discuss different situations with different charges that influence the system's phase structure. There is only a Hawking-Page phase transition in the absence of charges, which leads to an unstable small black hole. Hence, the related Page curve does not exist. However, a van der Waals-Maxwell-like phase transition occurs in the presence of charges. This yields three black hole solutions. The Page curve of the middle size black hole does not exist. For the extremal black hole, the Page time approaches zero in the phase transition situation but becomes divergent without the phase transition. In a word, we study the Page curve and the island paradigm for different black hole phases and in different phase transition situations.
