description: Contexte : Il est observé un vieillissement de la population en Suisse, qui implique une augmentation du nombre de personnes âgées entrant en EMS, où leur état de santé y est toujours plus précaire. De par son état de santé et des contraintes institutionnelles, le résident perd sa capacité à s’occuper de lui-même, ainsi que les repères sur lesquels il avait construit son identité. Plusieurs enjeux identitaires accompagnent donc la personne âgée dans la transition que représente l’entrée en EMS. Objectif : Le but de ce travail est d’identifier des interventions infirmières permettant d’accompagner favorablement la transition identitaire vécue par le résident en EMS. Méthode : Revue de littérature établie à partir de deux bases de données, Pubmed et CINAHL. Sept articles y ont été retenus. Les critères d’inclusion de ce travail sont : des articles datant de moins de dix ans, rédigés en anglais ou en français, qui sont des études primaires, se déroulant dans des établissements médico-sociaux dont la population est âgée de 65 ans et plus. Les résultats obtenus ont ensuite été analysés et mis en perspective grâce à la théorie des Transitions de Meleis. Résultats : Plusieurs interventions infirmières ont été mises en évidence, cela peut être de favoriser et maintenir les liens sociaux, soutenir l’indépendance et l’autonomie à travers les activités du quotidien, accompagner la personne dans les choix des objets personnels à emporter pour permettre la continuité identitaire, ainsi que proposer des soins centrés sur la personne qui pourraient aider à l’adaptation au nouveau lieu de vie. Discussion : Pour accompagner la transition, il est important de soutenir les sentiments identitaires vécus par les résidents. Ces sentiments sont principalement les suivants : le sentiment de possession, le sentiment d’exister, le sentiment d’unité sociale et le sentiment de continuité temporelle.
$Υ(6S)$ and triangle singularity in $e^+e^- \to B_1(5721) \bar B \to Z_b(10610) \, π$

description: We discuss the possibility that production of final states with bottomonium and light mesons at the peak $Υ(6S)$ in the $e^+e^-$ annihilation at approximately 11.00 GeV is in fact due to a triangular singularity at the threshold of the heavy meson pair production $B_1(5721) \bar B + c.c.$ through the process $e^+e^- \to B_1(5721) \bar B \to Z_b(10610) \, π$. The presence of the hidden-bottom resonance $Z_b(10610)$ then explains the observed enhanced production of the final channels with both ortho- and para- bottomonium states, $Υ(nS) ππ$ and $h_b(kP) ππ$. The discussed mechanism also predicts a distinct pattern for production of hidden-bottom states at the $Υ(6S)$ energy that can be tested by experiment.

description: We consider a model of nomadic agents exploring and competing for time-varying location-specific resources, arising in crowdsourced transportation services, online communities, and in traditional location based economic activity. This model comprises a group of agents, and a set of locations each endowed with a dynamic stochastic resource process. Each agent derives a periodic reward determined by the overall resource level at her location, and the number of other agents there. Each agent is strategic and free to move between locations, and at each time decides whether to stay at the same node or switch to another one. We study the equilibrium behavior of the agents as a function of dynamics of the stochastic resource process and the nature of the externality each agent imposes on others at the same location. In the asymptotic limit with the number of agents and locations increasing proportionally, we show that an equilibrium exists and has a threshold structure, where each agent decides to switch to a different location based only on their current location's resource level and the number of other agents at that location. This result provides insight into how system structure affects the agents' collective ability to explore their domain to find and effectively utilize resource-rich areas. It also allows assessing the impact of changing the reward structure through penalties or subsidies.

description: We present a new self-regulating methodology for coordinating distributed team work called Algorithmic Autoregulation (AA), based on recent social networking concepts and individual merit. Team members take on an egalitarian role, and stay voluntarily logged into so-called AA sessions for part of their time (e.g. 2 hours per day), during which they create periodical logs - short text sentences - they wish to share about their activity with the team. These logs are publicly aggregated in a website and are peer-validated after the end of a session, as in code review. A short screencast is ideally recorded at the end of each session to make AA logs more understandable. This methodology has shown to be well-suited for increasing the efficiency of distributed teams working on Global Software Development (GSD), as observed in our reported experience in actual real-world situations. This efficiency boost is mainly achieved through 1) built-in asynchronous on-demand communication in conjunction with documentation of work, products, and processes, and 2) reduced need for central management, meetings or time-consuming reports. Hence, the AA methodology legitimizes and facilitates the activities of a distributed software team. It thus enables other entities to have a solid means to fund these activities, allowing for new and concrete business models to emerge for very distributed software development. AA has been proposed, at its core, as a way of sustaining self-replicating hacker initiatives. These claims are discussed in a real case-study of running a distributed free software hacker team called Lab Macambira.

description: We investigate the distribution of Faraday rotation measure (RM) in the M87 jet at arc-second scales by using archival polarimetric VLA data at 8, 15, 22 and 43 GHz. We resolve the structure of the RM in several knots along the jet for the first time. We derive the power spectrum in the arcsecond scale jet and find indications that the RM cannot be associated with a turbulent magnetic field with 3D Kolmogorov spectrum. Our analysis indicates that the RM probed on jet scales has a significant contribution of a Faraday screen associated with the vicinity of the jet, in contrast with that on kiloparsec scales, typically assumed to be disconnected from the jet. Comparison with previous RM analyses suggests that the magnetic fields giving rise to the RMs observed in jet scales have different properties and are well less turbulent than these observed in the lobes.

description: Recent observations of debris discs, believed to be made up of remnant planetesimals, brought a number of surprises. Debris disc presence does not correlate with the host star's metallicity, and may anti-correlate with the presence of gas giant planets. These observations contradict both assumptions and predictions of the highly successful Core Accretion model of planet formation. Here we explore predictions of the alternative Tidal Downsizing (TD) scenario of planet formation. In TD, small planets and planetesimal debris is made only when gas fragments, predecessors of giant planets, are tidally disrupted. We show that these disruptions are rare in discs around high metallicity stars but release more debris per disruption than their low [M/H] analogs. This predicts no simple relation between debris disc presence and host star's [M/H], as observed. A detected gas giant planet implies in TD that its predecessor fragment was not disputed, potentially explaining why DDs are less likely to be found around stars with gas giants. Less massive planets should correlate with DD presence, and sub-Saturn planets ($M_{p} \sim 50 \M_{\oplus}$) should correlate with DD presence stronger than sub-Neptunes ($M_{p} \leq 15 \M_{\oplus}$). These predicted planet-DD correlations will be diluted and weakened in observations by planetary systems' long term evolution and multi-fragment effects neglected here. Finally, although presently difficult to observe, DDs around M dwarf stars should be more prevalent than around Solar type stars.

We prove the existence of such descent for many Shimura varieties whose associated adjoint group has certain factors of type A or D. This includes a large family of Shimura varieties of abelian type. Our considerations and constructions are carried out purely at the level of Shimura data and group theory.

description: In this paper, we compare several event classification architectures defined on the point cloud representation of collider events. These approaches, which are based on the frameworks of deep sets and edge convolutions, circumvent many of the difficulties associated with traditional feature engineering. To benchmark our architectures against more traditional event classification strategies, we perform a case study involving Higgs boson decays to tau leptons. We find a 2.5 times increase in performance compared to a baseline ATLAS analysis with engineered features. Our point cloud architectures can be viewed as simplified versions of graph neural networks, where each particle in the event corresponds to a graph node. In our case study, we find the best balance of performance and computational cost for simple pairwise architectures, which are based on learned edge features.

description: The recent observed anomalous Hall effect in magic angle twisted bilayer graphene (TBG) aligned to hexagonal boron nitride (hBN) and unconventional ferroelectricity in Bernal bilayer graphene sandwiched by hBN present a new platform to tune the correlated properties in graphene systems. In these graphene-based moiré superlattices, the aligned hBN substrate plays an important role. In this paper, we analyze the effects of hBN substrate on the band structure of the TBG. By means of an atomistic tight-binding model we calculate the electronic properties of TBG suspended and encapsulated with hBN. Interestingly, we found that the physical properties of TBG are extremely sensitive to the presence of hBN and they may be completely different if TBG is suspended or encapsulated. We quantify these differences by analysing their electronic properties, optical conductivity and band topology. We found that the narrow bandwidth, band gap, local density of states and optical conductivity are significantly modified by the aligned hBN substrates. Interestingly, these electronic properties can be used as a signature of the alignment in experiment. Moreover, the TBG/hBN superlattices in the presence or absence of the two-fold rotation symmetry response differently to the external electric field. For the TBG suspended in the hBN, application of an electric field results in the charge unevenly distributed between graphene layers, which can be used to tune the strength of the valley Hall effect or the anomalous Hall effect. Such rich topological phase diagram in these systems may be useful for experiments.

description: The field of multiple view geometry has seen tremendous progress in reconstruction and calibration due to methods for extracting reliable point features and key developments in projective geometry. Point features, however, are not available in certain applications and result in unstructured point cloud reconstructions. General image curves provide a complementary feature when keypoints are scarce, and result in 3D curve geometry, but face challenges not addressed by the usual projective geometry of points and algebraic curves. We address these challenges by laying the theoretical foundations of a framework based on the differential geometry of general curves, including stationary curves, occluding contours, and non-rigid curves, aiming at stereo correspondence, camera estimation (including calibration, pose, and multiview epipolar geometry), and 3D reconstruction given measured image curves. By gathering previous results into a cohesive theory, novel results were made possible, yielding three contributions. First we derive the differential geometry of an image curve (tangent, curvature, curvature derivative) from that of the underlying space curve (tangent, curvature, curvature derivative, torsion). Second, we derive the differential geometry of a space curve from that of two corresponding image curves. Third, the differential motion of an image curve is derived from camera motion and the differential geometry and motion of the space curve. The availability of such a theory enables novel curve-based multiview reconstruction and camera estimation systems to augment existing point-based approaches. This theory has been used to reconstruct a "3D curve sketch", to determine camera pose from local curve geometry, and tracking; other developments are underway.

description: Cadre Théorique : La réalité virtuelle immersive est un moyen de traitement de plus en plus employé comme thérapie. C’est une technologie informatique qui plonge l’utilisateur dans un environnement virtuel. Cette technologie a déjà fait ses preuves dans divers domaines. Nous nous sommes intéressés à son implémentation dans le cadre du traitement de l’obésité, du surpoids ou de la sédentarité en promouvant l’activité physique. Ce travail a pour but de résumer et diffuser les résultats de la recherche et d’identifier les lacunes de la recherche dans la littérature existante. Méthode : Cette scoping review a retenu six articles afin de traiter notre population (les personnes en surpoids, obèses et/ou sédentaire), notre concept (la réalité virtuelle immersive) et notre contexte (à but thérapeutique, articles publiés après l’année 2010 et avec comme issue clinique l’activité physique). Résultats : Les informations clés retrouvées dans nos études ont été exposées à l’aide d’un tableau et d’un détail des données écrites. Les pistes et lacunes de recherches ont été regroupées dans un tableau afin de les présenter succinctement. Conclusion : Ce moyen de traitement manque encore d’études avec un haut de niveau de preuve en lien avec notre PCC. Les résultats sont prometteurs dans les trois études expérimentales afin d’atteindre les recommandations d’activité physique. Cependant, il existe potentiellement des désavantages à l’utilisation de la réalité virtuelle. De plus, la conception des jeux en réalité virtuelle immersive est importante car l’adaptation aux capacités physiques influence l’adhésion aux traitements et leur efficacité.

description: The branching ratio of the structure dependent (SD) radiative $K^{+} \to e^{+} ν_{e} γ$ decay relative to that of the $K^+\rightarrow e^+ ν_{e} (γ)$ decay including the internal bremsstrahlung (IB) process ($K_{e2(γ)}$) has been measured in the J-PARC E36 experiment using plastic scintillator/lead sandwich detectors. In the analysis, the effect of IB was also taken into account in the SD radiative decay as $K_{e2γ(γ)}^{\rm SD}$. By combining the new data with the previously reported result of the E36 experiment using a CsI(Tl) calorimeter after revision for the IB correction for $K_{e2γ(γ)}^{\rm SD}$, a new value $Br(K_{e2γ(γ)}^{\rm SD})/Br(K_{e2(γ)})=1.20\pm0.07$ has been determined, which is consistent with a recent lattice QCD calculation, but larger than the expectation of Chiral Perturbation Theory (ChPT) at order $O(p^4)$ and the previous KLOE value. Also, using the method to relate form factor and branching ratio described in the KLOE paper, the present result is consistent with the form factor prediction based on a gauged nonlocal chiral quark model, but larger than ChPT at order $O(p^6)$.

DeepGlow: an efficient neural-network emulator of physical afterglow models for gamma-ray bursts and gravitational-wave events

description: Gamma-ray bursts (GRBs) and double neutron-star merger gravitational wave events are followed by afterglows that shine from X-rays to radio, and these broadband transients are generally interpreted using analytical models. Such models are relatively fast to execute, and thus easily allow estimates of the energy and geometry parameters of the blast wave, through many trial-and-error model calculations. One problem, however, is that such analytical models do not capture the underlying physical processes as well as more realistic relativistic numerical hydrodynamic (RHD) simulations do. Ideally, those simulations are used for parameter estimation instead, but their computational cost makes this intractable. To this end, we present DeepGlow, a highly efficient neural network architecture trained to emulate a computationally costly RHD-based model of GRB afterglows, to within a few percent accuracy. As a first scientific application, we compare both the emulator and a different analytical model calibrated to RHD simulations, to estimate the parameters of a broadband GRB afterglow. We find consistent results between these two models, and also give further evidence for a stellar wind progenitor environment around this GRB source. DeepGlow fuses simulations that are otherwise too complex to execute over all parameters, to real broadband data of current and future GRB afterglows.

description: The number density of galaxy clusters as a function of mass and redshift is a sensitive function of the cosmological parameters. To use clusters for cosmological parameter studies, it is necessary to determine their masses as accurately as possible, which is typically done via mass-observable scaling relations. X-ray observables can be biased by multiphase gas and projection effects, especially in the case where cluster temperatures and luminosities are estimated from single-model fits to all of the emission with a given radius. Using simulated galaxy clusters from a realistic cosmological simulation, we seek to determine the importance of these biases in the context of Spectrum-Roentgen-Gamma/eROSITA observations of clusters. We extract clusters from the Magneticum suite, and simulate eROSITA observations of these clusters using PHOX and SIXTE. We compare the fitted observables from these observations to those derived from the simulations. We fitted an intrinsically scattered $L_{\rm X}-T$ scaling relation to these measurements following a Bayesian approach with which we fully took into account the selection effects and the mass function. The largest biases on the cluster observables come from the inadequacy of single-temperature model fits to represent emission from multiphase gas, as well as a bias arising from cluster emission within the projected $r_{500c}$ along the line of sight but outside of the spherical $r_{500c}$. We find that the biases on temperature and luminosity due to the projection of emission from other clusters within $r_{500c}$ is small. We find that our simulated clusters follow a $L_{\rm X}-T$ scaling relation that has a broadly consistent but slightly shallower slope compared to the literature, and that the intrinsic scatter of $L_{\rm X}$ at given T is lower compared to the recent observational results where the selection effects are fully considered.

description: The current design of space-based gravitational wave detectors utilizes heterodyne laser interferometry in inter-satellite science measurements. Frequency variations of the heterodyne beatnotes are predominantly caused by the Doppler effect from relative satellite motion along lines of sight. Generally considered to be outside the measurement band, this Doppler frequency shift appears to have been overlooked in numerical simulations of time-delay interferometry (TDI). However, the potential impact on the implementation of TDI should be assessed. The issue is particularly relevant to TianQin that features geocentric orbits, because of strong gravity disturbances from the Earth-Moon system at frequencies $<1\times 10^{-4}$ Hz. In this proof-of-principle study, based on high-precision orbital data obtained from detailed gravity field modeling, we incorporate the Doppler shift in the generation of TianQin's beatnote phase signals. To remove the large-scale Doppler phase drift at frequencies $<1\times 10^{-4}$ Hz, we develop a high-performance high-pass filter and consider two possible processing sequences, i.e., applying the filter before or after TDI combinations. Our simulation results favor the former and demonstrate successful removal of the low-frequency gravity disturbances for TianQin without degrading the TDI performance, assuming 10 m pseudo-ranging uncertainty. The filtering scheme can be used in developing the initial noise-reduction pipeline for TianQin.

description: The free energy of TAP-solutions for the SK-model of mean field spin glasses can be expressed as a nonlinear functional of local terms: we exploit this feature in order to contrive abstract REM-like models which we then solve by a classical large deviations treatment. This allows to identify the origin of the physically unsettling quadratic (in the inverse of temperature) correction to the Parisi free energy for the SK-model, and formalizes the $\textit{true}$ cavity dynamics which acts on TAP-space, i.e. on the space of TAP-solutions. From a non-spin glass point of view, this work is the first in a series of refinements which addresses the stability of hierarchical structures in models of evolving populations.

description: The IceCube Neutrino Observatory detects GeV-to-PeV+ neutrinos via the Cherenkov light produced by secondary charged particles from neutrino interactions with the South Pole ice. The detector consists of over 5000 spherical Digital Optical Modules (DOM), each deployed with a single downward-facing photomultiplier tube (PMT) and arrayed across 86 strings over a cubic-kilometer. IceCube has measured the astrophysical neutrino flux, searched for their origins, and constrained neutrino oscillation parameters and cross sections. These were made possible by an in-depth characterization of the glacial ice, which has been refined over time, and novel approaches in reconstructions that utilize fast approximations of Cherenkov yield expectations. After over a decade of nearly continuous IceCube operation, the next generation of neutrino telescopes at the South Pole are taking shape. The IceCube Upgrade will add seven additional strings in a dense infill configuration. Multi-PMT OMs will be attached to each string, along with improved calibration devices and new sensor prototypes. Its denser OM and string spacing will extend sensitivity to lower neutrino energies and further constrain neutrino oscillation parameters. The calibration goals of the Upgrade will help guide the design and construction of IceCube Gen2, which will increase the effective volume by nearly an order of magnitude.

description: Introduction : Le modèle de périodisation linéaire présente des défauts qui nuisent à la demande accrue de performance des athlètes. De là est née la périodisation inversée qui a déjà démontré de meilleurs résultats quant à l’amélioration de la force musculaire, de l’endurance musculaire et des capacités aérobiques. L’objectif principal de l’étude est de déterminer les effets des périodisations inversées et linéaires sur l’amélioration des performances en natation. L’objectif secondaire est d’identifier les effets des périodisations inversées et linéaires sur différents facteurs de performance en natation. Méthode : La recherche d’articles a été réalisée entre septembre 2021 et janvier 2022 sur les bases de données CINAHL, Embase, Pubmed et Google Scholar. Quatre articles ont été sélectionnés grâce aux critères d’inclusions : athlètes, natation, crawl, hommes et femmes, analysant les périodisations linéaires et inversées sur des outcomes tels que la performance, les composantes cinématiques de la natation, la variabilité cardiaque et la composition corporelle. Les articles choisis ont été analysés grâce à la grille Downs and Black modifiée. Résultats : Les études sur le 100 mètres crawl ont démontré une amélioration de la performance en faveur de la périodisation inversée et une diminution de celle-ci pour la périodisation linéaire. Aucune amélioration constatée pour la performance sur 50 mètres. Conclusion : Des résultats favorables ont été obtenus par la périodisation inversée sur 100 mètres. Il est cependant nécessaire d’avoir plus de littérature afin de définir plus spécifiquement les modifications qu’engendre une périodisation inversée sur les paramètres de la performance en natation.

Résultats et discussion : Les alumni ont évoqué l’importance de la vie estudiantine au cours de leur formation, loué la qualité de l’enseignement, en particulier les mises en situation réelles, et souligné l’investissement des professeurs. Les stages sont unanimement considérés comme le lieu où l’on apprend le plus. L'intérêt des semaines interprofessionnelles apparait depuis que les alumni sont confrontés à la réalité du terrain. En revanche, ils ont regretté que certains contenus ne soient pas abordés pendant la formation, et le manque de cours pratiques dans certains domaines. Interrogés sur les enjeux futurs pour la formation en physiothérapie, les alumni estiment que la prévention devrait faire partie intégrante de la formation. Ils encouragent les étudiants à se battre pour plus de reconnaissance professionnelle. Enfin, c’est avant tout le savoir-être, qui pour eux fait un bon physiothérapeute.

description: Introduction : Les patients atteints de lombalgie voient leur manière de bouger modifiée. En effet, la vitesse et l’amplitude de mouvement sont diminuées. Actuellement, la mesure de ces paramètres est réalisée via des moyens coûteux et peu accessibles. En clinique, il serait pertinent que les thérapeutes aient en leur possession un moyen de mesure du mouvement fiable et valide. Le rôle de ce travail de Bachelor est d’évaluer la fiabilité intra-évaluateur ainsi que la validité de critère de l’outil de mesure du mouvement du tronc de l’application smartphone DigiBack. Méthodologie : La flexion et les inclinaisons du tronc ont été mesurées sur cinq sujets à raison de dix répétitions par minute avec le smartphone positionné au sternum et au bassin. Des coefficients de corrélation intraclasse (ICC 2.1), des erreurs standard de mesure (SEM) et des changements minimaux détectables (MDC) ont été calculés pour la fiabilité intra-évaluateur. Des coefficients de corrélations entre DigiBack et le Vimove ont été calculés pour la validité de critère. Les mouvements (flexion et inclinaisons) ont été segmentés et mesurés trois fois. Résultats : Les ICC se situaient entre 0,53 et 0,96 (IC95), les SEM entre 1,24° et 2,73° et les MDC entre 3,45° et 7,76°. Les mesures prises au sternum corrélaient avec le capteur thoracique du Vimove (0,89 et 0,91) et les mesures au bassin avec le capteur sacré (0,84 et 0,95). Seules les inclinaisons mesurées au sternum corrélaient avec l’angle lombaire (0,82 et 0,83). Discussion : À ce stade des recherches, la flexion mesurée au sternum avec DigiBack semble fiable et valide, tandis que les résultats des inclinaisons sont plus contrastés. L’utilisation d’applications mobiles dans la lombalgie semble dès lors être un moyen de mesure du mouvement en continu intéressant. Conclusion : L’application a apporté des résultats encourageants, cependant de futures études comprenant un nombre de sujets plus important seraient nécessaires pour confirmer si les résultats obtenus s’appliquent sur une population lombalgique. Cette étude n’est pas encore suffisante pour recommander une utilisation de l’application dans la clinique.

description: INTRODUCTION : En ventilation non-invasive (VNI), l’AUTO-Trigger et l’Auto-Trak sont deux algorithmes automatiques permettant l’ajustement du trigger inspiratoire et expiratoire de l’aide inspiratoire. OBJECTIF : Comparer la synchronisation inspiratoire (index d’asynchronies (IA)) et expiratoire (temps de déphasage entre le cyclage du ventilateur et l’arrêt de l’effort inspiratoire) de ces deux algorithmes sur un banc d’essai. MÉTHODE : Deux ventilateurs équipés des algorithmes respectifs ont été connectés à un simulateur pulmonaire informatisé modélisant trois mécaniques respiratoires (sain, restrictive et obstructive) avec trois niveaux d’efforts inspiratoires (2, 8 et 15 cmH2O) et deux fréquences respiratoires (15 et 25 respirations par minutes (rpm)). RÉSULTATS : L’AUTO-Trigger et l’Auto-Trak génèrent des temps de déphasage expiratoire significativement différents (p<0.001) dans toutes les conditions mécaniques respiratoires. Avec une mécanique saine ou restrictive, une précocité du cyclage à 15 rpm (saine respectivement, -23.5ms (-33ms ; -2ms) versus-54ms (-55ms ; -53ms) ; restrictive respectivement, -134.5ms (-148ms ; -123ms) versus-184ms (-184ms ; -184ms)) et un retard de cyclage à 25 rpm (saine respectivement, 158ms (158ms ; 160ms) versus133ms (133ms ; 135ms) ; restrictive respectivement, 80ms (80ms ; 80ms) versus39ms (39ms ; 39ms)) ; avec une mécanique obstructive, un retard du cyclage à 15 rpm respectivement 97ms (86ms ; 105ms) et 219ms (209ms ; 22 ms) et à 25 rpm respectivement 216ms (205ms ; 219ms) et 854.5ms (834ms ; 865ms). L’IA, évaluant la synchronisation inspiratoire, montre la présence d’efforts non-récompensés dans la mécanique obstructive avec un effort inspiratoire de 2 cmH2O. CONCLUSION : L’ajustement du trigger expiratoire de l’AUTO-Trigger et, plus particulièrement, de l’Auto-Trak semble moins performant avec l’augmentation de la fréquence respiratoire et dans les conditions mécaniques obstructives.

description: Interference between single photons is key for many quantum optics experiments and applications in quantum technologies, such as quantum communication or computation. It is advantageous to operate the systems at telecommunication wavelengths and to integrate the setups for these applications in order to improve stability, compactness and scalability. A new promising material platform for integrated quantum optics is lithium niobate on insulator (LNOI). Here, we realise Hong-Ou-Mandel (HOM) interference between telecom photons from an engineered parametric down-conversion source in an LNOI directional coupler. The coupler has been designed and fabricated in house and provides close to perfect balanced beam splitting. We obtain a raw HOM visibility of (93.5+/-0.7)%, limited mainly by the source performance and in good agreement with off-chip measurements. This lays the foundation for more sophisticated quantum experiments in LNOI

description: We study theoretically the polarization dynamics in a ring-shape bosonic condensate of exciton-polaritons confined in a rotating trap. The interplay between the rotating potential and TE-TM splitting of polariton modes offers a tool of control over the spin state and the angular momentum of the condensate. Specific selection rules describing the coupling of pseudospin and angular momentum are formulated. The resonant coupling between states having linear and circular polarizations leads to the polarization beats. The effect may be seen as a polariton analogy to the electronic magnetic resonance in the presence of constant and rotating magnetic fields. Remarkably, spin beats are induced by a purely mechanical rotation of the condensate.

description: The size of the smallest detectable sample feature in an x-ray imaging system is usually restricted by the spatial resolution of the system. This limitation can now be overcome using the diffusive dark-field signal, which is generated by unresolved phase effects or the ultra-small-angle x-ray scattering from unresolved sample microstructures. A quantitative measure of this dark-field signal can be useful in revealing the microstructure size or material for medical diagnosis, security screening and materials science. Recently, we derived a new method to quantify the diffusive dark-field signal in terms of a scattering angle using a single-exposure grid-based approach. In this manuscript, we look at the problem of quantifying the sample microstructure size from this single-exposure dark-field signal. We do this by quantifying the diffusive dark-field signal produced by 5 different sizes of polystyrene microspheres, ranging from 1.0 $μ$m to 10.8 $μ$m, to investigate how the strength of the dark-field signal changes with the sample microstructure size, $S$. We also explore the feasibility of performing single-exposure dark-field imaging with a simple equation for the optimal propagation distance given microstructure with a specific size and thickness, and successfully verify this equation with experimental data. Our theoretical model predicts that the dark-field scattering angle is inversely proportional to $\sqrt{S}$, which is consistent with our experimental data.

description: First-quantized eigensolver (FQE) is a recently proposed framework of quantum computation for obtaining the ground state of an interacting electronic system based on probabilistic imaginary-time evolution. In this study, we propose a method for introducing a uniform magnetic field to an FQE calculation. We demonstrate via resource estimation that the additional circuit responsible for the magnetic field can be implemented with a liner depth in terms of the number of qubits assigned to each electron, giving rise to no impact on the leading order of whole computational cost. We confirm the validity of our method via numerical simulations for ground and excited states by employing the filtration circuits for energy eigenstates. We also provide the generic construction of derivative circuits together with measurement-based formulae. As a special case of them, we can obtain the electric-current density in an electronic system to get insights into the microscopic origin of magnetic response.

description: Introduction : les douleurs gynécologiques chroniques représentent un enjeu majeur dans la société. Elles ont un impact conséquent d’un point de vue social, économique et culturel. Aucun consensus ne semble exister pour l’instant quant à la prise en charge de ces douleurs. La thérapie somatocognitive (TSC), hybride entre physiothérapie et psychothérapie, s’avère cependant prometteuse. Objectif : comprendre l’impact d’une approche biopsychosociale sur la douleur, la qualité de vie, l’anatomie posturale et le mouvement des femmes souffrant de ces douleurs chroniques. Le but est d’offrir une recommandation au monde de la physiothérapie afin d’optimiser la prise en charge et d’améliorer la qualité des soins. Méthode : les études sélectionnées prennent en compte des femmes ayant des douleurs gynécologiques chroniques sans étiologie connue, depuis au moins six mois et ayant bénéficié d’une intervention par l’approche somatocognitive. Résultats : cette revue de la littérature inclut trois études quantitatives et deux qualitatives. L’approche somatocognitive a été prodiguée à cinquante-sept patientes au total. Toutes les études quantitatives ont démontré des résultats significatifs. De plus, les études qualitatives mettent en lumière la perception positive d’une telle thérapie aux yeux des patientes et des physiothérapeutes. Conclusion : la TSC est une thérapie prometteuse dans le traitement des douleurs gynécologiques chroniques, car elle diminue la douleur et améliore la qualité de vie, l’anatomie posturale et le mouvement. C’est une thérapie qui semble pertinente également dans le traitement des douleurs chroniques en général. Cela réduirait considérablement les coûts de la santé associés aux traitements de ce type de maux.
