description: L’influence de la corrosion par piqûre et de sa variabilité spatiale sur la probabilité de défaillance des structures maritimes en béton armé est largement reconnue. Classiquement, la perte de masse associée est modélisée comme le produit de la perte de masse sous corrosion généralisée et d’un facteur de piqûre. Simple en apparence, cette approche souffre de l’hétérogénéité des modèles de densité de courant de corrosion, qui complique leur comparaison et leur sélection. Elle manque aussi de confrontation des valeurs expérimentales des facteurs de piqûre avec les résultats numériques. Ce travail aborde ces deux difficultés par (i) le recensement des modèles de densité de corrosion existants (hors éléments-finis) en utilisant un formalisme spécifique facilitant leur comparaison, (ii) l’évaluation des hyperparamètres de loi marginale du facteur de piqûre dans le cas d’étude d’une poutre de quai en béton armé dont on dispose de données d’inspection. Après sélection du modèle semi-analytique de Pour-Ghaz, on montre que la distribution de Gumbel couramment utilisée n’est valable que pour de faibles valeurs de résistivité, et nos résultats correspondent aux résultats expérimentaux de la littérature selon lesquels les paramètres de localisation et d’échelle sont des fonctions puissance décroissantes de la perte de masse généralisée. Dans ce cas, nous déterminons des lois pour ces paramètres.

description: Background: Thymic epithelial tumors (TETs) are relatively rare malignant thoracic tumors. Tumor mutation burden (TMB) and immune infiltration play important roles in tumorigenesis. Methods: Research data was obtained using the Cancer Genome Atlas (TCGA) database to evaluate the landscape of tumor mutations, related factors, and relationship of prognosis. The CIBERSORT algorithm was used to evaluate immune cell infiltration in TETs and its relationship with TMB. Immune-related differentially expressed genes (irDEGs) were identified. Hub irDEGs independently related to prognosis were analyzed using univariate and multivariate Cox proportional hazard models. A survival signature was constructed from hub irDEGs. Results A total of 122 patients were included in this study. GTF2I was the most common gene mutation. Higher TMB was significantly associated with the later stage, more advanced pathological type, and older age. The overall survival (OS) of patients in the low-TMB group was significantly better. There was no significant correlation between TMB levels and PD-L1 expression. Enrichment analysis showed that DEGs were mainly involved in the P13K-Akt signaling pathway. There were significant differences in macrophage and other types of immune cell infiltration between the high- and low-TMB groups. CCR5, FASLG, and CD79A independently relating to prognosis were screened from 391 irDEGs. The low-risk group had a significantly better prognosis than the high-risk group based on the signature, which has a good predictive effect on OS. Conclusions: In this study, TETs patients with high TMB had a significantly poor prognosis and an immune-related gene signature was found to effectively evaluate the long-term prognosis.

description: In colorectal cancer, oncogenic mutations transform a hierarchically organized and homeostatic epithelium into invasive cancer tissue lacking visible organization. We sought to define transcriptional states of colorectal cancer cells and signals controlling their development by performing single-cell transcriptome analysis of tumors and matched non-cancerous tissues of twelve colorectal cancer patients. We defined patient-overarching colorectal cancer cell clusters characterized by differential activities of oncogenic signaling pathways such as mitogen-activated protein kinase and oncogenic traits such as replication stress. RNA metabolic labeling and assessment of RNA velocity in patient-derived organoids revealed developmental trajectories of colorectal cancer cells organized along a mitogen-activated protein kinase activity gradient. This was in contrast to normal colon organoid cells developing along graded Wnt activity. Experimental targeting of EGFR-BRAF-MEK in cancer organoids affected signaling and gene expression contingent on predictive KRAS/BRAF mutations and induced cell plasticity overriding default developmental trajectories. Our results highlight directional cancer cell development as a driver of non-genetic cancer cell heterogeneity and re-routing of trajectories as a response to targeted therapy.

description: Les mesures de résistivité électrique sont appliquées aux bétons depuis plusieurs décennies, notamment pour leur sensibilité aux teneurs en eau et en ions chlorures, paramètres essentiels lorsqu’on s’intéresse à la durabilité des ouvrages. Pour passer des résistances de transfert mesurées aux résistivités apparentes, il est nécessaire de bien estimer les facteurs géométriques correspondants. Ces facteurs dépendent de la géométrie et des dimensions du spécimen de béton ausculté, ainsi que des positions des électrodes et de leurs formes. Or les géométries de mesure se complexifient de plus en plus, notamment avec le développement de capteurs multi-électrodes noyés, avec des électrodes non ponctuelles et des structures de capteurs plus influentes. De telles géométries sont actuellement déployées dans deux projets ANR (SCaNING et DEMCOM), pour lesquels l’estimation précise de nombreux facteurs géométriques est nécessaire à l’analyse des données. Cet article rappelle différentes approches qui permettent l’estimation des facteurs géométriques, ainsi que leurs limitations. Il propose ensuite une méthodologie numérique permettant de cadrer ces estimations. Des configurations tirées des deux projets illustrent la démarche.

Critical Curves and Caustics of Triple-lens Models

description: Among the 25 planetary systems detected up to now by gravitational microlensing, there are two cases of a star with two planets, and two cases of a binary star with a planet. Other, yet undetected types of triple lenses include triple stars or stars with a planet with a moon. The analysis and interpretation of such events is hindered by the lack of understanding of essential characteristics of triple lenses, such as their critical curves and caustics. We present here analytical and numerical methods for mapping the critical-curve topology and caustic cusp number in the parameter space of $n$-point-mass lenses. We apply the methods to the analysis of four symmetric triple-lens models, and obtain altogether 9 different critical-curve topologies and 32 caustic structures. While these results include various generic types, they represent just a subset of all possible triple-lens critical curves and caustics. Using the analyzed models, we demonstrate interesting features of triple lenses that do not occur in two-point-mass lenses. We show an example of a lens that cannot be described by the Chang-Refsdal model in the wide limit. In the close limit we demonstrate unusual structures of primary and secondary caustic loops, and explain the conditions for their occurrence. In the planetary limit we find that the presence of a planet may lead to a whole sequence of additional caustic metamorphoses. We show that a pair of planets may change the structure of the primary caustic even when placed far from their resonant position at the Einstein radius.

Stigma, fear of compassion and chronic pain
Creators: name: Timney, John
Publisher: name: Lancaster University
Year: 2020

description: Section one details a thematic synthesis that sought to understand men’s experiences of chronic pain. Systematic searches of CINAHL, MEDLINE, PubMed and PsycINFO identified 14 qualitative studies. Five domains were identified: ‘The effort and unpredictability of being in pain’, ‘Becoming a burden’, ‘Being judged as less of a man’, ‘Trying to hold on to a ‘masculine’ identity’ and ‘Rebuilding and rehabilitating’. Domains were interconnected and represented a process following pain onset. Men initially described a wish to control both the pain and its impact on their daily lives. Reductions in daily functioning and the effect of social judgements led men to feel burdensome and the prevailing Western masculine hegemony shaped men’s responses to these stigmatising experiences. Over time, men built a new understanding of the self, renegotiating their masculinity and sought to rebuild and rehabilitate. Section two describes correlation analyses, hierarchical linear regressions and moderation analyses that sought to understand if: (1) stigma, fear of compassion from others (FOCO) and fear of compassion from self (FOCS) independently predict outcomes of painrelated anxiety, depression or pain interference, and (2) FOCO or FOCS moderate the relationship between pain intensity or stigma and outcomes of psychological distress. FOCO and FOCS significantly correlated with depression, anxiety and pain interference. Pain intensity and stigma were independent predictors of depression, anxiety and pain interference. FOCO significantly predicted depression and anxiety but not pain interference. FOCS predicted depression but not anxiety or pain interference. For the first time in chronic pain, FOCO was demonstrated to moderate the relationship between stigma and depression. This study demonstrates that FOC is an important psychological factor in the experiences of individuals with chronic pain. Section three provides a critical appraisal of the work presented in this thesis, including an exploration of the impact of the COVID-19 pandemic on the process.

description: Collage at times refuses to be contained; it spills over the paper substrate and ruptures the idea of kept order. This thesis examines collage as a material strategy to address gendered mis(s)representations of women that I am confronted with in my everyday. Acknowledging collages political agency alongside methodological research on feminism, intertextual strategies and modes of transgression provides new understandings as well as alternative forms to visually express being in one's body and in the world. Writers Georges Bataille and Kathy Acker demonstrate how transgressive tendencies evoke an outsider’s political agency using abject signification to question systems of order and hegemonic power. My process-based art practice looks at works of art and ideas that promote or demonstrate an affective undoing. Employing humour invites the absurd, the dark and the grotesque to disrupt idealized notions of the feminine. The heart of my investigation looks to push the boundaries of otherness and bad taste in hopes of answering my central research question: Can one affect the conventional order of things through transgressive renderings of the female form?

description: Les ingénieurs sont confrontés à un défi majeur lorsqu'ils évaluent la résistance in-situ des structures en béton : la fiabilité de la valeur estimée. De ce fait, cette étude se concentre sur un élément important du programme d'investigation : la sélection des emplacements principaux pour l'extraction des carottes. Différents plans d'échantillonnage ont été étudiés, à savoir le carottage conditionnel (RILEM), l'échantillonnage par similarité, l'échantillonnage proportionnel stratifié et l'échantillonnage par optimisation de la variance. Des courbes de risque ont été générées pour évaluer la qualité de l'estimation de chaque plan d'échantillonnage. L'objectif de notre étude est d'analyser cette problématique dans le cadre d'un vaste programme d'investigation, en appliquant des techniques non destructives (rebond et ultrasons) et carottage sur des composants structurels d'un bâtiment existant. L'évaluation des deux quantités estimées (résistance moyenne, variabilité de la résistance) a été effectuée en utilisant deux approches d'identification de modèle : bi-objectif pour une technique de CND unique et multi-objectif pour la combinaison de deux techniques de CND. Une analyse statistique complète des données a permis d'estimer l'intérêt potentiel des différents plans d'échantillonnage par rapport au carottage aléatoire. Il est également nécessaire d'évaluer et de comparer les différentes stratégies d'échantillonnage afin de déterminer la plus efficace. Le but de cette étude est de fournir des recommandations aux ingénieurs, afin de créer un programme d'investigation optimal pour l'évaluation de la résistance du béton.

description: We study the dynamical melting of "hot" one-dimensional many-body localized systems. As disorder is weakened below a critical value these non-thermal quantum glasses melt via a continuous dynamical phase transition into classical thermal liquids. By accounting for collective resonant tunneling processes, we derive and numerically solve an effective model for such quantum-to-classical transitions and compute their universal critical properties. Notably, the classical thermal liquid exhibits a broad regime of anomalously slow sub-diffusive equilibration dynamics and energy transport. The subdiffusive regime is characterized by a continuously evolving dynamical critical exponent that diverges with a universal power at the transition. Our approach elucidates the universal long-distance, low-energy scaling structure of many-body delocalization transitions in one dimension, in a way that is transparently connected to the underlying microscopic physics.

description: Temat śmierci i pytanie „co się z nami dzieje, gdy umrzemy” prześladuje ludzkość od wieków. Rick Riordan stworzył cykl powieści dla dzieci i młodzieży „Percy Jackson i Bogowie Olimpijscy" (2005–2009) o herosie, który żyje w XXI wieku. Amerykański pisarz przywołuje do współczesnych realiów starożytny grecki panteon i obszary panowania naczelnych bogów. Mitologiczne zaświaty zostają przeniesione w powieści Riordana do naszych realiów. Współcześni bohaterowie mają poważne wyzwania, a jednym z nich jest zejście do mrocznej krainy zmarłych. W swoim artykule chciałabym przeanalizować motyw katabazy, który pojawił się w powieści. Literatura współczesna często wykorzystuje elementy mitologii starożytnej Grecji. To ciekawe zjawisko świadczy o fakcie, że antyk pozostaje żywą sferą odniesień i funkcjonuje w naszym codziennym życiu. The subject of death and the question what is happening to us, how we are dying, persecutes humanity for centuries. Rick Riordan created a series of novels for children and young people: "Percy Jackson & the Olympians" (2005–2009) about the hero who lives in the 21st century. The American writer refers to the modern realities of the ancient Greek pantheon and areas of the reign of the chief gods. Mythological worlds are transferred in Riordan's novel to our realities. Modern heroes have serious challenges, one of which is entrance to the dark land of the dead, where one of the three sons of Kronos and his wife, the goddess Persephone, prevail. In my article I would like to analyze the theme of katabasis that appeared in the novel.

description: Pour évaluer la méthode de localisation de dommages SDDLV, un benchmark à partir des données issues uniquement de capteurs a été proposé. Des essais ont été réalisés en laboratoire sur une maquette à l'échelle 1/200 de la travée centrale du pont de Saint-Nazaire équipée d'accéléromètres. Le dommage introduit simule la rupture d'une paire de câbles supportant le pont. La méthode SDDLV a permis d'identifier les modifications de la matrice de souplesses de la maquette en exploitant les données mesurées par des accéléromètres soumis à un bruit blanc. Dans un second temps, un modèle éléments finis de la structure est utilisé dans le cadre d'une analyse statique pour la cartographie des éléments endommagés sans qu'il soit nécessaire de le mettre à jour. Sur la maquette, un endommagement particulier a pu être correctement localisé dans un contexte où d'une part le décalage fréquentiel entre l'état sain et l'état endommagé n'est que de l'ordre de 1% pour les modes de vibrations utiles à l'analyse et que d'autre part la correspondance entre les modes calculés par éléments finis et les modes identifiés lors des essais n'est qu'approximative.

description: Interacting quantum spin models are remarkably useful for describing different types of physical, chemical, and biological systems. Significant understanding of their equilibrium properties has been achieved to date, especially for the case of spin models with short-range couplings. However, progress towards the development of a comparable understanding in long-range interacting models, in particular out-of-equilibrium, remains limited. In a recent work, we proposed a semiclassical numerical method to study spin models, the discrete truncated Wigner approximation (DTWA), and demonstrated its capability to correctly capture the dynamics of one- and two-point correlations in one dimensional (1D) systems. Here we go one step forward and use the DTWA method to study the dynamics of correlations in 2D systems with many spins and different types of long-range couplings, in regimes where other numerical methods are generally unreliable. We compute spatial and time-dependent correlations for spin-couplings that decay with distance as a power-law and determine the velocity at which correlations propagate through the system. Sharp changes in the behavior of those velocities are found as a function of the power-law decay exponent. Our predictions are relevant for a broad range of systems including solid state materials, atom-photon systems and ultracold gases of polar molecules, trapped ions, Rydberg, and magnetic atoms. We validate the DTWA predictions for small 2D systems and 1D systems, but ultimately, in the spirt of quantum simulation, experiments will be needed to confirm our predictions for large 2D systems.

description: Les travaux menés dans le cadre du projet ANR-SCaNING visent à développer des capteurs noyés dans le béton afin de suivre l’évolution d’indicateurs de durabilité du béton dans le temps. En effet, pour évaluer les indicateurs avec précision, il est nécessaire de combiner des mesures ultrasonores, résistives et électromagnétiques, ce qui implique une organisation complexe dans la structure et des systèmes de pilotage différents. L’objectif de cet article n’est pas de décrire les capteurs mais de présenter l’architecture de la maquette en béton armé instrumentée et pilotée à distance en justifiant les choix par rapport aux besoins de l’évaluation non destructive des indicateurs de performance du matériau (résistance et porosité) et des profils de suivi de l’état du béton notamment de teneur en eau. Tout d’abord, la maquette est dimensionnée et chaque type de capteur positionné. Ensuite, les systèmes de génération, pilotage des mesures et communication avec le serveur de contrôle sont détaillés. Enfin, les recommandations des projets de recherche précédents relatives à l’évaluation non destructive des indicateurs de durabilité du béton ouvriront vers une discussion sur les besoins spécifiques du suivi en continu de ces indicateurs pour les structures en béton armé.

Non-thermal quantum channels as a thermodynamical resource

description: Quantum thermodynamics can be understood as a resource theory, whereby thermal states are free and the only allowed operations are unitary transformations commuting with the total Hamiltonian of the system. Previous literature on the subject has just focused on transformations between different state resources, overlooking the fact that quantum operations which do not commute with the total energy also constitute a potentially valuable resource. In this Letter, given a number of non-thermal quantum channels, we study the problem of how to integrate them in a thermal engine so as to distill a maximum amount of work. We find that, in the limit of asymptotically many uses of each channel, the distillable work is an additive function of the considered channels, computable for both finite dimensional quantum operations and bosonic channels. We apply our results to bound the amount of distillable work due to the natural non-thermal processes postulated in the Ghirardi-Rimini-Weber (GRW) collapse model. We find that, although GRW theory predicts the possibility to extract work from the vacuum at no cost, the power which a \emph{collapse engine} could in principle generate is extremely low.

description: Le composite cimentaire fibré ultra performant (CFUP) est devenu populaire en Suisse pour la conception de structures légères et durables. Les éléments structuraux en CFUP armé sont étanches et ont une grande durabilité. En raison de sa composition unique, le CFUP possède des propriétés mécaniques spécifiques. En particulier, le développement précoce des propriétés du CFUP, comme le module d'élasticité, est difficile à étudier, car il se produit lorsque les éléments sont encore dans leur coffrage. Cet article propose une nouvelle méthode de mesures combinant une surveillance passive grâce aux émissions acoustiques et une surveillance active via des ultrasons. Ce système de mesures a été intégré dans une poutre avec une section transversale en T qui a une longueur de 4,2 mètres. Le réseau de surveillance se compose de 24 transducteurs ultrasoniques ainsi que de 15 thermocouples, permettant la collecte de données en continu dès le début du processus de durcissement du CFUP. Après 28 jours, la poutre a été décoffrée puis testée en flexion quatre points. Cette campagne de mesures a permis de documenter avec précision l'évolution des propriétés du CFUP au jeune âge, ainsi que le comportement structurel et les processus d’endommagement de la poutre pendant les essais de charge jusqu’à la rupture.

description: Model-based analysis tools, built on assumptions and simplifications, are difficult to handle smart grids with data characterized by 4Vs data. This paper, using random matrix theory (RMT), motivates data-driven tools to perceive the complex grids in highdimension; meanwhile, an architecture with detailed procedures is proposed. In algorithm perspective, the architecture performs a high-dimensional analysis, and compares the findings with RMT predictions to conduct anomaly detections. Mean Spectral Radius (MSR), as a statistical indicator, is defined to reflect the correlations of system data in different dimensions. In management mode perspective, a group-work mode is discussed for smart grids operation. This mode breaks through regional limitations for energy flows and data flows, and makes advanced big data analyses possible. For a specific large-scale zone-dividing system with multiple connected utilities, each site, operating under the group-work mode, is able to work out the regional MSR only with its own measured/simulated data. The large-scale interconnected system, in this way, is naturally decoupled from statistical parameters perspective, rather than from engineering models perspective. Furthermore, a comparative analysis of these distributed MSRs, even with imperceptible different raw data, will produce a contour line to detect the event and locate the source. It demonstrates that the architecture is compatible with the block calculation only using the regional small database; beyond that, this architecture, as a data-driven solution, is sensitive to system situation awareness, and practical for real large-scale interconnected systems. Five case studies and their visualizations validate the designed architecture in various fields of power systems. To our best knowledge, this study is the first attempt to apply big data technology into smart grids.

description: Un suivi par des méthodes électrochimiques non destructives d’armatures métalliques en acier au carbone et en aciers inoxydables est mené en parallèle depuis 10 ans pour deux types d’exposition : d’une part, des conditions accélérées avec une addition de chlorures au gâchage et avec une exposition en enceinte climatique pour les prismes ; et d’autre part, des conditions naturelles dans le port de La Rochelle pour les poutrelles. Le potentiel libre des armatures se situent pour les 2 expositions à des valeurs similaires : ≈ -500 mV/ECS pour l’acier et ≈ -50 mV/ECS pour le 1.4362. La densité de courant de corrosion est très élevée pour les prismes en acier standard, ce qui est due à la forte corrosion initiée par les ions chlorures. Par contre, dans les deux cas, la densité de corrosion de l’inox 1.4362 est très faible après 10 ans soit 0,001 µA/cm2 pour les prismes et 0,2 µA/cm2 pour les poutrelles, ce qui traduit l’absence de corrosion.

description: Objective We have recently shown that mesenchymal stem cells (MSCs) embedded in a hyaluronic acid (HA) hydrogel and exposed to chondrogenic factors (transforming growth factor-3 [TGF-3]) produce a cartilage-like tissue in vitro. The current objective was to determine if these same factors could be combined immediately prior to implantation to induce a superior healing response in vivo relative to the hydrogel alone. Design Trochlear chondral defects were created in Yucatan mini-pigs (6 months old). Treatment groups included an HA hydrogel alone and hydrogels containing allogeneic MSCs, TGF-3, or both. Six weeks after surgery, micro-computed tomography was used to quantitatively assess defect fill and subchondral bone remodeling. The quality of cartilage repair was assessed using the ICRS-II histological scoring system and immunohistochemistry for type II collagen. Results Treatment with TGF-3 led to a marked increase in positive staining for collagen type II within defects (P < 0.05), while delivery of MSCs did not (P > 0.05). Neither condition had an impact on other histological semiquantitative scores (P > 0.05), and inclusion of MSCs led to significantly less defect fill (P < 0.05). For all measurements, no synergistic interaction was found between TGF-3 and MSC treatment when they were delivered together (P > 0.05). Conclusions At this early healing time point, treatment with TGF-3 promoted the formation of collagen type II within the defect, while allogeneic MSCs had little benefit. Combination of TGF-3 and MSCs at the time of surgery did not produce a synergistic effect. An in vitro precultured construct made of these components may be required to enhance in vivo repair in this model system.

description: Crossref, DataCite and ORCID work together to provide a foundational open infrastructure that is integral to the global research ecosystem. We offer unique, persistent identifiers (PIDs) — Crossref and DataCite DOIs for research outputs and ORCID iDs for people — alongside collecting comprehensive, open metadata that is non-proprietary, accessible, interoperable, and available across borders, disciplines, and time. As sustainable community-driven scholarly infrastructure providers ORCID, Crossref and Datacite, guarantee data provenance and machine-readability. Persistent identifiers combined with open, standardized, and machine-readable metadata enable reliable and robust connections to be made between research outputs, organizations, individuals and much more, as well as being beneficial to others who build services and tools on top of the open infrastructure we provide making content more discoverable. In his presentation, Mohamad Mostafa shares an introduction to DataCite comprehensive approach in increasing global PIDs adoption through DataCite Global Access Program (GAP).

description: Mit der Einführung einer neuen Governance der Hochschulen sollte ab den 1990er-Jahren nicht nur die Steuerung des Hochschulbereichs, sondern durch die Verknüpfung mit Zielen der Geschlechtergleichstellung auch die Durchsetzungskraft von Gleichstellungspolitik verbessert werden (vgl. Zimmermann 2016). Eine Verbesserung war notwendig, denn die Geschlechterverhältnisse in der Wissenschaft hatten sich seit Ende der 1980er-Jahre nur sehr langsam angeglichen (vgl. GWK 2021).

description: We study the polarization efficiency (defined as the ratio of polarization to extinction) of stars in the background of the small, nearly spherical and isolated Bok globule CB4 to understand the grain alignment process. A decrease in polarization efficiency with an increase in visual extinction is noticed. This suggests that the observed polarization in lines of sight which intercept a Bok globule tends to show dominance of dust grains in the outer layers of the globule. This finding is consistent with the results obtained for other clouds in the past. We determined the distance to the cloud CB4 using near-infrared photometry (2MASS JHKS colors) of moderately obscured stars located at the periphery of the cloud. From the extinction-distance plot, the distance to this cloud is estimated to be ($459 \pm 85$) pc.

Recovery of precious metals from end-of-life PEMFCs

description: The growing prevalence of fuel cell technology has helped grow its stature in the public eye. It has gained praise for all the sustainable model and accessibility of power. With this sustained period in the public eye certain parts of fuel cells have also experienced scrutiny. One of these aspects is the cost of fuel cells comparative to their fossil fuel counterpart. It is estimated that 34% of the cost of a fuel cell stack is composed of the precious metal catalysts found within the fuel cell membrane. Due to this cost it is important to find a technique that can recover as much of these catalysts as possible at the lowest available cost. This paper looks to analyse the current methods that are employed in industry to determine the best and most economic routes to explore. Hydrometallurgical methods are explored within this paper after it was deemed the most appropriate method available. Exploring the effects of both platinum and iridium upon the same membrane is also developed with the aim of creating a process that can selectively leach each metal from a membrane surface. By creating such a mechanism, catalysts can be treated and recycled – hence lowering the overall cost of the fuel stack and creating a more economically viable energy source. This paper seeks to explore different hydrometallurgical processes that allow for effective dissolution of platinum and iridium. By varying oxidant concentration as well as pH many avenues were explored including corrosion by halide-based solvents.

description: We study the rare decays of B meson. We want to constraint the NSIs by using these reactions. We show that there is a strong dependence of these reactions on new physics parameter. We include second and third generation of quarks in the loop for these decays. We further point out that the constraints for second generation are more precise as compared to second and third. We further point out that for inclusive decay, the u quark induce NSIs are giving very very small contribution. We also study KL rare decay to pi zero, neutrino and anti-neutrino. We also study the interference between the standard model and NSIs.
