description: On 2$^{nd}$ October 2012 the NIST (National Institute of Standards and Technology) in the United States of America announced the new hashing algorithm which will be adopted as standard from now on. Among a total of 73 candidates, the winner was Keccak, designed by a group of cryptographers from Belgium and Italy. The public selection of a new standard of cryptographic hash function SHA (Secure Hash Algorithm) took five years. Its object is to generate a hash a fixed size from a pattern with arbitrary length. The first selection on behalf of NIST on a standard of this family took place in 1993 when SHA-1 was chosen, which later on was replaced by SHA-2. This paper is focused on the analysis both from the point of view of security and the implementation of the Keccak function, which is the base of the new SHA-3 standard. In particular, an implementation in the mobile platform Android is presented here, providing the first known external library in this mobile operating system so that any developer could use the new standard hashing. Finally, the new standard in applications in the Internet of Things is analysed.

description: Introduction : les douleurs d’épaule chez les personnes paraplégiques sont fréquentes. Elles sont non seulement dues à la sursollicitation ou mauvaise utilisation de l’articulation lors de l’usage du fauteuil roulant manuel, mais elles s’ajoutent aussi au vieillissement physiologique de l’épaule. Ces douleurs amènent à différentes limitations dans la vie quotidienne des paraplégiques. Objectif : recenser et analyser les différentes activités douloureuses en fauteuil roulant manuel et les associer à certaines caractéristiques démographiques des paraplégiques. Méthodologie : la recherche documentaire a été réalisée sur les bases de données PubMed, CINHAL et PEDro. Les études quantitatives traitant des douleurs d’épaule chez les personnes paraplégiques ont été sélectionnées successivement par titre, résumé puis texte intégral en fonction de critères d’inclusions préalablement établis. Résultats : sept études ont été incluses, dont six études transversales et une étude randomisée contrôlée. Les activités les plus douloureuses sont le déplacement sur plan incliné, le lever de charges, la propulsion de plus de 10 minutes et les transferts. Les caractéristiques démographiques spécifiques, tels que le sexe, l’âge, le niveau lésionnel, le temps post-lésionnel et le poids ont une influence sur les résultats en favorisant l’apparition de douleurs d’épaule. Conclusion : ce travail fait le lien entre les activités douloureuses et les mécanismes lésionnels impliqués. Il permet de démontrer l’importance d’une prise en charge physiothérapeutique personnalisée. De futures recherches sont néanmoins nécessaires pour valider l’effet d’une telle prise en charge sur les douleurs d’épaule des paraplégiques.

description: Introduction : Les adaptations musculaires entrainées par la pratique sportive modifient la balance musculaire chez les sportifs d’armer-lancer. Les pathologies de sursollicitation de l’épaule sont parmi les principales causes d’arrêt de l’activité sportive chez cette population. L’identification de facteurs de risque permettrait au physiothérapeute d’adapter la réhabilitation de l’athlète et la prévention de blessures. Objectif : Déterminer les intérêts de l’évaluation isocinétique de la force musculaire des rotateurs médiaux et latéraux d’épaule dans la prévention des blessures chez les sportifs d’armer-lancer. Méthodologie : Ce travail est une revue systématique quantitative de la littérature. Les recherches ont été effectuées dans Pubmed, CINHAL, Web of Science, ScienceDirect et PEDro entre septembre 2013 et janvier 2014. Résultats : Sept études rétrospectives et/ou prospectives ont été incluses dans la revue. Les auteurs évaluent les moments de force maximale concentrique et excentrique ainsi que les ratios conventionnels et fonctionnels chez les groupes « blessure » et « non blessure ». Plusieurs études mettent en évidence un déficit de force excentrique des rotateurs d’épaule chez le groupe « blessure ». Conclusion : La mise en place d’un consensus dans le protocole isocinétique d’évaluation des rotateurs d’épaule est essentielle pour une comparaison rigoureuse entre les études. Le déséquilibre musculaire semble être un facteur de risque de blessures chez cette population. Les auteurs recommandent un renforcement excentrique des rotateurs médiaux et latéraux chez les sportifs d’armer-lancer.

description: Bulk electrical dissipation caused by charge-density-wave (CDW) depinning and sliding is a classic subject. We present a novel local, nanoscale mechanism describing the occurrence of mechanical dissipation peaks in the dynamics of an atomic force microscope tip oscillating above the surface of a CDW material. Local surface 2$π$ slips of the CDW phase are predicted to take place giving rise to mechanical hysteresis and large dissipation at discrete tip surface distances. The results of our static and dynamic numerical simulations are believed to be relevant to recent experiments on NbSe$_2$; other candidate systems in which similar effects should be observable are also discussed.

description: In some situations the communications of a place can be affected, totally lost, or not even exist. In these cases, the MANETs play an important role, allowing to establish a communications point using the different nodes of the network to reach the destination using decentralized communications. This paper proposes the implementation of a Robotic MANET, a decentralized network using robots as its nodes, which allows to move the network nodes to the desired location remotely. For this, each robot has as a core a Raspberry Pi with the capabilities to perform audio and video streaming, remote control of robots, tracking of objects, and deployment of wireless networks. To protect the network, different security mechanisms are used that allow secure authentication on the network by different nodes and encryption of information transmitted between them. All communications are protected through Identity-Based Cryptography, specifically with an Identity-Based Signcryption scheme.

description: We report results of quantum efficiency (QE) measurements carried out on a 150 nm thick nitrogen-incorporated ultrananocrystalline diamond terminated with hydrogen; abbreviated as (N)UNCD:H. (N)UNCD:H demonstrated a QE of $\sim$10$^{-3}$ ($\sim$0.1%) at 254 nm. Moreover, (N)UNCD:H was sensitive in visible light with a QE of $\sim$5$\times$10$^{-8}$ at 405 nm and $\sim$5$\times$10$^{-9}$ at 436 nm. After growth and prior to QE measurements, samples were exposed to air for about 2 hours for transfer and loading. Such design takes advantage of a key combination: 1) H-termination inducing negative electron affinity (NEA) on the (N)UNCD and stabilizies its surface against air exposure; and 2) N-incorporation inducing $n$-type conductivity in intrinsically insulating UNCD.

description: Introduction : La population des lésés médullaires est à haut risque de développer des douleurs neuropathiques. Les traitements de ces dernières sont limités et essentiellement médicamenteux. Les thérapies d’imagerie motrice (IM) et de la marche virtuelle (MV) nécessitent peu de moyens, rentrent dans les compétences du physiothérapeute et peuvent potentiellement répondre à cette problématique. Objectif : L’objectif de cette revue est d’analyser les effets de l’IM et de la MV sur les douleurs neuropathiques des personnes lésées médullaires. Méthodes : Les recherches documentaires ont été effectuées dans les bases de données Medline-PubMed, The Cochrane Library, CINAHL et PEDro aux moyens de mots-clés et descripteurs. Seules les études respectant les critères d’inclusion sont intégrées. Résultats : Quatre articles ont été retenus : trois études de cas et un essai contrôlé randomisé. Les résultats obtenus pour l’intervention de l’IM varient d’une exacerbation des symptômes à une légère diminution des douleurs, avec des modalités d’utilisation différentes. Pour les deux études sur la marche virtuelle, les auteurs constatent, dans la plupart des cas, une diminution des douleurs. Conclusion : L’IM analytique est à proscrire car elle exacerbe les douleurs. L’IM fonctionnelle et la MV diminuent les douleurs neuropathiques mais nécessitent davantage d’investigations. Les résultats de cette Revue systématique (RS) démontrent que la MV peut offrir une nouvelle direction de traitement pour cette population. Des pistes susceptibles d’améliorer les effets de ces thérapies sont proposées.
On the diversity of magnetic interactions in close-in star-planet systems

description: Magnetic interactions between close-in planets and their host star can play an important role in the secular orbital evolution of the planets, as well as the rotational evolution of their host. As long as the planet orbits inside the Alfvén surface of the stellar wind, the magnetic interaction between the star and the planet can modify the wind properties and also lead to direct angular momentum transfers between the two. We model these star-planet interactions using compressible magneto-hydrodynamic (MHD) simulations, and quantify the angular momentum transfers between the star, the planet, and the stellar wind. We study the cases of magnetized and non-magnetized planets and vary the orbital radius inside the Alfvén surface of the stellar wind. Based on a grid of numerical simulations, we propose general scaling laws for the modification of the stellar wind torque, for the torque between the star and the planet, and for the planet migration associated with the star-planet magnetic interactions. We show that when the coronal magnetic field is large enough and the star is rotating sufficiently slowly, the effect of the magnetic star-planet interaction is comparable to tidal effects and can lead to a rapid orbital decay.

Lockdown
Phenomenological perspective
Digital methods

description: The research investigates the social effects of the atypical domestic containment situation during the Covid-19 emergency in Italy. The survey, which is placed in a phenomenological perspective, shows how individuals and the community have been able to develop an adaptation or resilience process to the lockdown in order to conform their life to the “new ordinary”, making it real and purposeful. The research process, which was entirely conducted digitally through specific software for qualitative analysis, has developed dynamically, following the Grounded Theory approach. Facebook posts and Instagram audio tracks combined with newspaper articles represent the cases of the research. While on one hand, digitality has allowed an individual the perception of normality by feeling part of a community, on the other it has revealed various forms of digital divide, characterized by different levels of literacy at school, at work and domestically. The social disadvantage does not exclusively concern the digital world but rather on the lockdown that has heightened the systematic exclusion of the most fragile sections of the population.
The Local Group's mass: probably no more than the sum of its parts

description: The total mass of the Local Group (LG) and the masses of its primary constituents, the Milky Way and M31, are important anchors for several cosmological questions. In recent years, independent measurements have consistently yielded halo masses close to $10^{12} \mathrm{M_\odot}$ for the MW, and $1-2 \times 10^{12} \mathrm{M_\odot}$ for M31, while estimates derived from the pair's kinematics via the `timing argument' have yielded a combined mass of around $5 \times 10^{12} \mathrm{M_\odot}$. Here, we analyse the extremely large Uchuu simulation to constrain the mass of the Local Group and its two most massive members. First, we demonstrate the importance of selecting LG analogues whose kinematics are dominated by mutual interactions to a similar extent as the LG. Adopting the observed separation and radial velocity, we obtain a weighted posterior of $75_{-40}^{+65}$ kms$^{-1}$ for the uncertain transverse velocity. Via Gaussian process regression, we infer a total mass of $3.2^{+1.2}_{-0.9} \times 10^{12} \mathrm{M_\odot}$, significantly below the timing argument prediction. Importantly, we show that the remaining uncertainty is not rooted in the analysis or observational errors, but in the irreducible scatter in the kinematics-mass relation. We further find a mass for the less massive halo of $0.9_{-0.3}^{+0.6} \times 10^{12} \mathrm{M_\odot}$ and for the more massive halo of $2.3_{-0.9}^{+1.0} \times 10^{12} \mathrm{M_\odot}$, consistent with independent measurements of the masses of MW and M31, respectively. Incorporating the mass of the MW as an additional prior allows us to further constrain all measurements and determine that the MW is very likely to be the lower mass object of the two.

Les étapes ultérieures suivent le cadre de réalisation du Travail de Bachelor en vigueur à HESAV. Résultats Trois études pilotes composent notre revue systématique. Le protocole et les modalités d’application du massage varient. L’outcome et l’outil de mesure (goniomètre) sont identiques. Nos études rapportent une augmentation statistiquement significative de l’amplitude articulaire. Discussion Les limites des études empêchent une généralisation des résultats. Les auteur(e)s ne les expliquent pas. Ils n’évoquent pas les effets démontrés du massage sur la douleur et l’amélioration cutanée, alors que ceux-ci agissent indirectement sur les rétractions cutanées et la mobilité articulaire. Aucunes recommandations sur les modalités d’application les plus efficaces de l’intervention n’est possible. Conclusion Le massage cicatriciel manuel est un bon adjuvant à une physiothérapie standard pour traiter la mobilité articulaire des brûlés. Les modalités d’application les plus efficaces devraient être mises en évidence par d’autres études.

description: Fault injection attacks represent an effective threat to embedded systems. Recently, Laurent et al. have reported that fault injection attacks can leverage faults inside the microarchitecture. However, state-of-the-art counter-measures, hardwareonly or with hardware support, do not consider the integrity of microarchitecture control signals that are the target of these faults. We present MAFIA, a microarchitecture protection against fault injection attacks. MAFIA ensures integrity of pipeline control signals through a signature-based mechanism, and ensures fine-grained control-flow integrity with a complete indirect branch support and code authenticity. We analyse the security properties of two different implementations with different security/overhead trade-offs: one with a CBC-MAC/Prince signature function, and another one with a CRC32. We present our implementation of MAFIA in a RISC-V processor, supported by a dedicated compiler toolchain based on LLVM/Clang. We report a hardware area overhead of 23.8 % and 6.5 % for the CBC-MAC/Prince and CRC32 respectively. The average code size and execution time overheads are 29.4 % and 18.4 % respectively for the CRC32 implementation and are 50 % and 39 % for the CBC-MAC/Prince.

description: Contexte : La BPCO est une pathologie fréquente qui conduit à un handicap important. La réhabilitation pulmonaire a été prouvée comme étant une intervention efficace. Cependant, chez les patients les plus sévèrement atteints, l’intensité de l'entraînement peut être limitée, diminuant ainsi les bénéfices attendus de la réhabilitation pulmonaire. Différentes stratégies ont été étudiées afin d’optimiser les gains de cette intervention, dont la VNI nocturne. Objectif: Le but de ce travail est de déterminer l’efficacité de l’adjonction nocturne de la VNI à un programme de réentrainement à l’effort chez les patients BPCO stables. Méthodologie : Les recherches ont été faites sur PubMed, Cinahl, Embase et PEDro, en incluant des articles parus de 1990 au 31 décembre 2013. Les études retenues devaient comprendre de la VNI nocturne en adjonction à un programme de réentrainement à l’effort sur des patients BPCO sévères et stables. Résultats : Nous avons réuni 302 articles, dont finalement 4 ont été retenus. Il s’agit de 3 RCTs et d’une étude cas-témoin, dont la qualité méthodologique a été jugée moyenne. Selon les études, la VNI nocturne en adjonction au réentrainement montre des résultats bénéfiques sur la capacité fonctionnelle, la qualité de vie, la PaCO2, ainsi que sur le maintien à long terme du VEMS. Conclusion : L’adjonction nocturne de la VNI à un programme de réentraînement à l’effort chez les patients BPCO sévères semble être une alternative intéressante pour optimiser les résultats bénéfiques de la réhabilitation pulmonaire. Cependant d’autres études sont nécessaires pour confirmer ces résultats.

description: This paper describes a solution for the efficient management of revocation in vehicular ad-hoc networks, for both certificate-based and identity-based authentication. It proposes the use of an authenticated data structure based on a dynamic hash tree, which is a perfect $k$-ary tree, together with a new version of the SHA-3 hash function. This combination allows optimizing search and insertion operations in the tree. Consequently, the proposal is very useful both when vehicular networks are widely used, and in urban environments. Simulation results are promising and confirm this hypothesis.

description: The footprint of LoTSS-DR2 covers 309 PSZ2 galaxy clusters, 83 of which host a radio halo and 26 host a radio relic(s). It provides us an excellent opportunity to statistically study the properties of extended cluster radio sources, especially their connection with merging activities. We aim to quantify cluster dynamic states to investigate their relation with the occurrence of extended radio sources. We also search for connections between intracluster medium (ICM) turbulence and nonthermal characteristics of radio halos in the LoTSS-DR2. We analyzed XMM-Newton and Chandra archival X-ray data and computed concentration parameters and centroid shifts that indicate the dynamic states of the clusters. We also performed a power spectral analysis of the X-ray surface brightness (SB) fluctuations to investigate large-scale density perturbations and estimate the turbulent velocity dispersion. The power spectral analysis results in a large scatter density fluctuation amplitude. We therefore only found a marginal anticorrelation between density fluctuations and cluster relaxation state, and we did not find a correlation between density fluctuations and radio halo power. Nevertheless, the injected power for particle acceleration calculated from turbulent dissipation is correlated with the radio halo power, where the best-fit unity slope supports the turbulent (re)acceleration scenario. Two different acceleration models, transit-time damping and adiabatic stochastic acceleration, cannot be distinguished due to the large scatter of the estimated turbulent Mach number. We introduced a new quantity $[kT\cdot Y_X]_{r_\mathrm{RH}}$, which is proportional to the turbulent acceleration power assuming a constant Mach number. This quantity is strongly correlated with radio halo power, where the slope is also unity.

description: I reviewed current study on Ni – based catalysts used in the methane steam reforming (MSR) reaction and the roles of different type of promoters in the first two sections of Chapter 1. I noticed that most studies only focus on half of the big picture: coke formation. Particle sintering has mainly been considered and studied as a result of coking. Besides, the roles of promoters also often entangle with particle size and support effects. In the last section, I also reviewed the principle and application of calorimetry that has been employed in this dissertation.
description: In Chapter 2, I studied MSR reaction over Ni – FAU prepared by ion exchange and Ni - Mo2C/FAU in which Mo was introduced by impregnation. The results indicate that the deactivation of Ni - FAU is due to sintering and the addition of Mo2C inhibits Ni sintering process through promoting CH4 decomposition. Besides, excellent stability of Mo2C supported on zeolite Y was also observed and therefore in Chapter 3 and 4, employing high temperature oxides melt calorimetry, I systematically studied the thermodynamics of MoO3 and Mo2C supported on FAU with different Si/Al ratios. Our data show that 1) the interaction between Mo2C/MoO3 and FAU decreases with increasing Si/Al ratios; 2) the interaction between Mo2C and FAU is much stronger than that between MoO3 and FAU.
description: Another important factor determining catalysts’ performance is the interaction of reactants with active sites. With the assistance of direct gas adsorption calorimetry, I performed water adsorption on copper – mordenite (Chapter 5) and ruthenium supported on activated carbon (Chapter 6) which are one of the most promising catalysts for methane – to – methanol reaction and biomass hydrodeoxygenation reaction, respectively. Water is chosen as probe molecule because it’s either a reactant, a product, or impurity and plays important roles in the reaction processes.
description: Subsequently, I expand the thermodynamic study to energy storage materials such as transition metal layered double hydroxides (LDHs) (Chapter 7). By coupling multiple technologies, I elucidate that NiAl-LDHs become less stable as the Ni/Al ratio increases. Moreover, water–LDH interactions is important in stabilizing the excessive Ni sites on the surface.
Probing Layer Localization in Twisted Graphene Bilayers via Cyclotron Resonance

description: Electron wavefunctions in twisted bilayer graphene may have a strong single layer character or be intrinsically delocalized between layers, with their nature often determined by how energetically close they are to the Dirac point. In this paper, we demonstrate that in magnetic fields, optical absorption (cyclotron resonance) spectra contain signatures which may be used to distinguish the nature of these wavefunctions at low energies, as well as to locate low energy critical points in the zero-field energy spectrum. Optical absorption for two different configurations -- electric field parallel and perpendicular to the bilayer -- are calculated, which are shown to have different selection rules with respect to which states are connected by the perturbation. Interlayer bias further distinguishes transitions involving states of a single layer nature from those with support in both layers. For doped systems, a sharp increase in intra-Landau level absorption occurs with increasing field as the level passes through the zero-field saddle point energy, where the states change character from single layer to bilayer.

description: This is a demonstration of the capabilities of generative AI for producing a set of learning objectives for each course of the GW Mechanical and Aerospace Engineering department, based on the brief descriptions listed on the course bulletin.Of course, this demo is not intended to suggest that course learning objectives should be auto-generated. It is only meant to showcase the capability, and spark the imagination of readers to the possibilities of highly productive human-AI collaboration in curriculum-development tasks.
Bright dipolar Bose-Einstein condensate soliton mobile in a direction perpendicular to polarization

description: We demonstrate stable, robust, bright dipolar Bose-Einstein condensate (BEC) solitons, moving in a direction perpendicular to the polarization direction, formed due to dipolar interaction for repulsive contact interaction. At medium velocity the head on collision of two such solitons is found to be quasi elastic with practically no deformation. Upon small perturbation the solitons are found to exhibit sustained breathing oscillation. The findings are illustrated by numerical simulation using the 3D mean-field Gross-Pitaevskii equation and a reduced 2D model in three and two spatial dimensions employing realistic interaction parameters for a dipolar $^{164}$Dy BEC.

description: Introduction : L’accident vasculaire cérébral (AVC) est la première cause de handicap acquis à l’âge adulte dans le monde. La prise en charge précoce de cette pathologie dès l’hospitalisation en milieu aigu est essentielle. Cependant un manque de clarté subsiste quant au délai optimal pour commencer à mobiliser et quant aux effets de la mobilisation précoce sur l’indépendance fonctionnelle. Objectif : Déterminer les effets de la mobilisation précoce à moyen et long terme sur l’indépendance fonctionnelle des patients victimes d’un AVC et identifier si d’autres facteurs peuvent influencer le niveau fonctionnel. Méthodologie : Une recherche systématique de la littérature a été réalisée de janvier 2013 à janvier 2014 sur les bases de données PubMed, CINAHL, PEDro et The Cochrane Library. La sélection des articles s’est faite selon des critères d’inclusion et d’exclusion prédéfinis. Les données des outils de mesure évaluant l’indépendance fonctionnelle ont été extraites et analysées afin d’observer les effets de la mobilisation précoce. Résultats : Cinq études ont été sélectionnées. Pour trois études, on observe une tendance en faveur de la mobilisation précoce. Pour les deux autres, elle est en défaveur. Cependant la majorité des résultats sont non-significatifs. Aucun autre facteur n’est significativement corrélé à un bon niveau fonctionnel. Conclusion : La mobilisation précoce semble avoir un effet sur la récupération de l’indépendance fonctionnelle des patients ayant eu un AVC. Cependant des recherches supplémentaires avec des échantillons plus importants sont nécessaires afin de confirmer notre hypothèse et de proposer un protocole de mobilisation optimale.

description: Introduction : Le modèle biopsychosocial considère le patient dans toutes ses dimensions. Il est actuellement le plus reconnu dans la prise en charge des douleurs chroniques. La thérapie cognitive et comportementale permet une approche globale et son efficacité sur la douleur a été prouvée. Son intégration dans le traitement du physiothérapeute représente donc un intérêt. Objectif : Explorer l’expérience vécue par des patients et des thérapeutes vis-à-vis de la thérapie cognitive et comportementale dans le cadre du traitement des douleurs chroniques. Méthodologie : Nous avons réalisé une revue de la littérature qualitative par l’analyse thématique de cinq articles, trois pour les patients, deux pour les thérapeutes. Résultats et discussion : Huit thèmes ont été dégagés de notre analyse. Quatre pour les patients, quatre pour les thérapeutes. Parmi ces thèmes, nous avons mis en lumière ceux qui nous semblent être les plus influents sur la qualité de l’expérience de la TCC. Nous discutons du point de vue du patient, du thérapeute, de leur expérience commune ainsi que des implications cliniques pour la physiothérapie. Conclusion : Le thérapeute est autant responsable que le patient pour la qualité de l’expérience commune de la TCC. Le thérapeute a par contre une large marge de manœuvre pour adapter la thérapie. Il se doit donc d’être attentif aux thèmes décrits tant chez le patient que chez le thérapeute pour rendre la thérapie confortable et profitable.

description: We analyse the full shape of anisotropic clustering measurements from the extended Baryon Oscillation Spectroscopic survey (eBOSS) quasar sample together with the combined galaxy sample from the Baryon Oscillation Spectroscopic Survey (BOSS). We obtain constraints on the cosmological parameters independent of the Hubble parameter $h$ for the extensions of the $Λ$CDM models, focusing on cosmologies with free dark energy equation of state parameter $w$. We combine the clustering constraints with those from the latest CMB data from Planck to obtain joint constraints for these cosmologies for $w$ and the additional extension parameters - its time evolution $w_{\rm{a}}$, the physical curvature density $ω_{K}$ and the neutrino mass sum $\sum m_ν$. Our joint constraints are consistent with flat $Λ$CDM cosmological model within 68\% confidence limits. We demonstrate that the Planck data are able to place tight constraints on the clustering amplitude today, $σ_{12}$, in cosmologies with varying $w$ and present the first constraints for the clustering amplitude for such cosmologies, which is found to be slightly higher than the $Λ$CDM value. Additionally, we show that when we vary $w$ and allow for non-flat cosmologies and the physical curvature density is used, Planck prefers a curved universe at $4σ$ significance, which is $\sim2σ$ higher than when using the relative curvature density $Ω_{\rm{K}}$. Finally, when $w$ is varied freely, clustering provides only a modest improvement (of 0.021 eV) on the upper limit of $\sum m_ν$.

Les effets de la méditation de pleine conscience chez les patients souffrant de douleurs musculo-squelettiques persistantes

subject: Mindfulness-Based Stress Reduction (MBSR)

description: Introduction : Les douleurs musculo-squelettiques persistantes ont de nombreuses conséquences physiques, psychiques ou sociales sur l’individu. Une approche bio-psycho-sociale est vivement recommandée dans leur prise en charge. La méditation de pleine conscience, en plein essor, permet un lien corps-esprit et pourrait être un moyen de traitement complémentaire aux thérapies conventionnelles. Objectif : Réaliser une Revue Systématique (RS) évaluant les effets du Mindfulness-Bases Stress Reduction (MBSR) sur la douleur, la qualité de vie et la dépression chez une population souffrant de douleurs musculo-squelettiques persistantes. Méthodologie : Les recherches documentaires ont été effectuées à partir des bases de données CINAHL, Cochrane, PubMed, Embase, PsychInfo et PEDro jusqu’en décembre 2013. Elles ont été complétées par une recherche manuelle. La sélection des études est basée sur les critères d’inclusion et d’exclusion. Résultats : Six études randomisées contrôlées de qualité variable ont été sélectionnées, incluant 442 sujets au total. Au vu du faible taux de résultats intergroupes significatifs obtenus, il semblerait que le programme MBSR ne soit pas plus efficace qu’un groupe contrôle sur les critères de jugement de cette RS. Conclusion : Les résultats à court et moyen termes ne permettent pas d’assurer l’avantage d’un groupe MBSR face à un groupe contrôle. Toutefois, ils sont à nuancer en raison des différents biais méthodologiques notamment que les études présentent. Ce travail permet de donner des pistes quant aux effets du MBSR sur les douleurs persistantes musculo-squelettiques. Cependant, de futures recherches sont nécessaires.

description: In the digital society, the traditional methods of social research for the study of so-ciety have been accompanied by innovative methodological proposals: digital and digitized methods , which are now applied to many themes. In 2020 the most de-bated topic was certainly the one concerning the Covid-19 pandemic; a “total social fact” of which not only the medical aspects have been analyzed, a substantial scien-tific production, indeed, has concerned the impacts that the pandemic itself and the measures that governments have taken to resist it has had on society. Starting from these considerations, the aim of this work is to offer an overview of the topics ana-lyzed and the research methods used to investigate this disruptive event in academ-ic research concerning the social sciences - and in particular that which focused on the Italian case - during the last year. To map the state of the art, consolidate the heterogeneous corpus of knowledge, and investigate the different methodological approaches used (tradition/digital/digitized) a methodological approach was ap-plied based on a systematic review of the literature conducted with the PRISMA method and carried out with a third type content analysis

description: Community structure can naturally emerge in paths to synchronization, and scratching it from the paths is a tough issue that accounts for the diverse dynamics of synchronization. In this paper, with assumption that the synchronization on complex networks is made up of local and collective processes, we proposed a scheme to lock the local synchronization (phase locking) at a stable state meanwhile suppress the collective synchronization based on Kuramoto model. Through this scheme, the network dynamics only contains the local synchronization, which suggests that the nodes in the same community synchronize together and these synchronization clusters well reveal the community structure of network. Furthermore, by analyzing the paths to synchronization, the relations or overlaps among different communities are also obtained. Thus, the community detection based on the scheme is performed on five real networks and the observed community structures are much more apparent than modularity-based fast algorithm. Our results not only provide a deep insight to understand the synchronization dynamics on complex network but also enlarge the research scope of community detection.
