description: Many data analytic systems have adopted a newly emerging compute resource, serverless (SL), to handle data analytics queries in a timely and cost-efficient manner, i.e., serverless data analytics. While these systems can start processing queries quickly thanks to the agility and scalability of SL, they may encounter performance- and cost-bottlenecks based on workloads due to SL's worse performance and more expensive cost than traditional compute resources, e.g., virtual machine (VM). In this project, we introduce Smartpick, a SL-enabled scalable data analytics system that exploits SL and VM together to realize composite benefits, i.e., agility from SL and better performance with reduced cost from VM. Smartpick uses a machine learning prediction scheme, decision-tree based Random Forest with Bayesian Optimizer, to determine SL and VM configurations, i.e., how many SL and VM instances for queries, that meet cost-performance goals. Smartpick offers a knob for applications to allow them to explore a richer cost-performance tradeoff space opened by exploiting SL and VM together. To maximize the benefits of SL, Smartpick supports a simple but strong mechanism, called relay-instances. Smartpick also supports event-driven prediction model retraining to deal with workload dynamics. A Smartpick prototype was implemented on Spark and deployed on live test-beds, Amazon AWS and Google Cloud Platform. Evaluation results indicate 97.05% and 83.49% prediction accuracies respectively with up to 50% cost reduction as opposed to the baselines. The results also confirm that Smartpick allows data analytics applications to navigate the richer cost-performance tradeoff space efficiently and to handle workload dynamics effectively and automatically.

Incorporation de la chènevotte dans les pavés drainants : une stratégie efficace pour atténuer les îlots de chaleur urbains
Creators: name: Haddad, Bechara

Year: 2023

description: L'effet d'îlot de chaleur urbain (ICU) pose des défis importants à la qualité de l'environnement urbain et à la santé publique. Au cours des décennies, des efforts de recherche ont été faits pour développer diverses stratégies d'atténuation de l'ICU, y compris des matériaux de revêtement, tels que les revêtements à rétention d'eau, les revêtements rétroréfléchissants et le béton perméable. Cet article se concentre sur l'amélioration des propriétés hydriques et de rétention d'eau du béton drainant pour atténuer les phénomènes d'ICU. Les tests hydriques ont été effectués sur quatre bétons différents où les granulats naturels ont été remplacés par la chènevotte. Les résultats montrent une amélioration significative de ces propriétés en augmentant leur efficacité de plus de 100 %, ce qui classe ce béton perméable comme une solution de revêtement de rétention d'eau pour l'atténuation de l'ICU.

Valorisation de cendres de biomasse : une alternative aux granulats naturels dans les bétons
Creators: name: SCHLUPP, Florian
Publisher: name: Academic Journal of Civil Engineering
Year: 2023

description: La filière bois énergie française génère annuellement des centaines de milliers de tonnes de cendres de biomasse. De part de leurs caractéristiques, les cendres sous-foyer (CSF) de biomasse pourraient être potentiellement valorisables en tant que matériau de construction. Ce qui permettra de diminuer la consommation de granulats naturels non renouvelables qui se raréfient et d’avoir un nouveau débouché à ces déchets industriels. La faisabilité d’incorporer des cendres de biomasse en remplacement du sable a été démontrée dans une étude préliminaire sur mortier, avec des taux de substitution volumique de 0 à 100 %. Bien qu’une diminution de la maniabilité ait été observée pour la formulation à 100 % de valorisation, la substitution de sable par des cendres de biomasse a permis d’obtenir de meilleures propriétés mécaniques. Ces résultats prometteurs ont été transposés de l’échelle du mortier vers la formulation de béton. Il a été démontré que la valorisation de 100 % de cendres de biomasse dans les bétons permet d’obtenir des résistances mécaniques semblables à la référence. Bien qu’une légère augmentation de la porosité accessible à l’eau soit observée, les autres propriétés mécaniques analysées (traction et module élastique) ont également montré des propriétés équivalentes à la référence.

description: We show that non-reciprocal bands can be formed in a magnetized periodic chain of spherical plasmonic particles with two particles per unit cell. Simplified form of symmetry operators in dipole approximations are used to demonstrate explicitly the relation between spectral non-reciprocity and broken spatial-temporal symmetries. Due to hybridization among plasmon modes and free photon modes, strong spectral non-reciprocity appears in region slightly below the lightline, where highly directed guiding of energy can be supported. The results may provide a clear guidance on the design of one-way waveguides.

description: We introduce text2fabric, a novel dataset that links free-text descriptions to various fabric materials. The dataset comprises 15,000 natural language descriptions associated to 3,000 corresponding images of fabric materials. Traditionally, material descriptions come in the form of tags/keywords, which limits their expressivity, induces pre-existing knowledge of the appropriate vocabulary, and ultimately leads to a chopped description system. Therefore, we study the use of free-text as a more appropriate way to describe material appearance, taking the use case of fabrics as a common item that non-experts may often deal with. Based on the analysis of the dataset, we identify a compact lexicon, set of attributes and key structure that emerge from the descriptions. This allows us to accurately understand how people describe fabrics and draw directions for generalization to other types of materials. We also show that our dataset enables specializing large vision-language models such as CLIP, creating a meaningful latent space for fabric appearance, and significantly improving applications such as fine-grained material retrieval and automatic captioning.

description: Afin d'évaluer le phénomène de fissuration dans les grandes structures en béton armé et précontraint, une simulation prédictive de l'endommagement du béton avec un maillage fin et une loi non linéaire est nécessaire. Du fait du coût de calcul, une telle modélisation n'est pas applicable à l’échelle de la structure complète. Pour résoudre cette difficulté, une méthode basée sur la condensation statique (Guyan, 1965), initialement proposée dans (Llau et al., 2015) puis développée dans (Mezher et al., 2022a) et (Mezher et al., 2022b), qui concentre l'effort de calcul sur la zone endommagée, a été proposée. Dans cette contribution, l'applicabilité et l'efficacité de l’ASC sont montrées sur la maquette à l'échelle 1/3 d'une enceinte de confinement (Vercors). L'ASC a permis d'atteindre des niveaux de simulations inaccessibles en calcul complet tout en utilisant un modèle d'endommagement non local pour le béton.

description: In this paper we argue that there is a trade-off between generativity and originality in online communities that support open collaboration. We build on foundational theoretical work in peer production to formulate and test a series of hypotheses suggesting that the generativity of creative works is associated with moderate complexity, prominent authors, and cumulativeness. We also formulate and test three hypotheses that these qualities are associated with decreased originality in resulting derivatives. Our analysis uses a rich data set from the Scratch Online Community --a large web-site where young people openly share and remix animations and video games. We discuss the implications of this trade-off for the design of peer production systems that support amateur creativity.

description: We report the physical properties and electronic structure calculations of a layered chromium oxypnictide, Sr$_2$Cr$_3$As$_2$O$_2$, which crystallizes in a Sr$_2$Mn$_3$As$_2$O$_2$-type structure containing both CrO$_2$ planes and Cr$_2$As$_2$ layers. The newly synthesized material exhibits a metallic conduction with a dominant electron-magnon scattering. Magnetic and specific-heat measurements indicate at least two intrinsic magnetic transitions below room temperature. One is an antiferromagnetic transition at 291 K, probably associated with a spin ordering in the Cr$_2$As$_2$ layers. Another transition is broad, occurring at around 38 K, and possibly due to a short-range spin order in the CrO$_2$ planes. Our first-principles calculations indicate predominant two-dimensional antiferromagnetic exchange couplings, and suggest a KG-type (i.e. K$_2$NiF$_4$ type for CrO$_2$ planes and G type for Cr$_2$As$_2$ layers) magnetic structure, with reduced moments for both Cr sublattices. The corresponding electronic states near the Fermi energy are mostly contributed from Cr-3$d$ orbitals which weakly (modestly) hybridize with the O-2$p$ (As-4$p$) orbitals in the CrO$_2$ (Cr$_2$As$_2$) layers. The bare bandstructure density of states at the Fermi level is only $\sim$1/4 of the experimental value derived from the low-temperature specific-heat data, consistent with the remarkable electron-magnon coupling. The title compound is argued to be a possible candidate to host superconductivity.

description: La prédiction et l'évaluation des propriétés de transfert du béton affecté par les Réactions de Gonflement Interne (RGI) est un défi majeur pour les experts engagés dans les tests de durabilité du béton. L'objectif de cette étude est de mesurer l'évolution de la perméabilité à l'air avec le développement des RGI, pour différents niveaux d’expansion et différents degrés de saturation du béton. Dans ce travail, deux RGI ont été étudiés : la Réaction Alcali-Silice (RSA) pour laquelle l'origine du gonflement se trouve dans les granulats, et la Réaction Sulfatique Interne (RSI) pour laquelle l'origine se situe dans la matrice cimentaire. Les premiers résultats obtenus montrent que le développement des RGI et des fissures induites conduit à une augmentation de la perméabilité à l'air des bétons, en particulier dans les bétons fortement saturés. Les données de cette étude permettent d'évaluer l'évolution des propriétés de transfert en fonction de l’expansion générée, de la fissuration induite et du degré de saturation du béton.

description: The class of joint decoder of probabilistic fingerprinting codes is of utmost importance in theoretical papers to establish the concept of fingerprint capacity. However, no implementation supporting a large user base is known to date. This article presents an iterative decoder which is, as far as we are aware of, the first practical attempt towards joint decoding. The discriminative feature of the scores benefits on one hand from the side-information of previously accused users, and on the other hand, from recently introduced universal linear decoders for compound channels. Neither the code construction nor the decoder make precise assumptions about the collusion (size or strategy). The extension to incorporate soft outputs from the watermarking layer is straightforward. An extensive experimental work benchmarks the very good performance and offers a clear comparison with previous state-of-the-art decoders.

Suffusion under different stress states
Creators: name: Oli, Bikram
Publisher: name: Academic Journal of Civil Engineering
Year: 2023

description: Internal erosion, caused by the movement of soil particles within a dam's embankment or foundation due to seepage, is a leading cause of dam failures worldwide. One mechanism of internal erosion is suffusion, which is the simultaneous detachment, transportation, and potential self-filtration of fine particles through pore spaces. To better understand this process, a modified triaxial bench was designed and commissioned. The device is able to apply head-controlled downward seepage flow at a specific stress state and independently control the stress state and the hydraulic loadings path. This study investigates the influence of various stress states on the initiation and development of suffusion in a gap-graded cohesionless soil using the modified triaxial erodimeter. The results show that the influence of the stress state on the erodibility classification is limited. RÉSUMÉ ( In French ) L'érosion interne est causée par le mouvement de particules de sol à l'intérieur d’un ouvrage hydraulique en terre ou du sol de fondation sous l’action d’un écoulement. Ce processus est l'une des principales causes d'instabilités de ces ouvrages dans le monde. Un des quatre mécanismes d'érosion interne est la suffusion, qui est le processus simultané du détachement, du transport et de la potentielle filtration de particules fines au travers de l’espace poral. Pour mieux comprendre ce processus, un banc triaxial modifié a été conçu et mis en service. Le dispositif est capable d'appliquer un écoulement vertical descendant contrôlé, suivant un état de contrainte spécifique. Il donne également la possibilité de commander indépendamment l'état de contrainte et les chemins de chargement hydraulique. A l’aide de ce dispositif, une campagne expérimentale est réalisée afin d’étudier l'influence des différents états de contrainte sur l'initiation et le développement de la suffusion dans un sol pulvérulent à distribution granulométrique lacunaire. Les résultats montrent que l'influence de l'état de contrainte sur la classification d'érodibilité est limitée.

description: In this paper, we use evidence from a remixing community to evaluate two pieces of common wisdom about collaboration. First, we test the theory that jointly produced works tend to be of higher quality than individually authored products. Second, we test the theory that collaboration improves the quality of functional works like code, but that it works less well for artistic works like images and sounds. We use data from Scratch, a large online community where hundreds of thousands of young users share and remix millions of animations and interactive games. Using peer-ratings as a measure of quality, we estimate a series of fitted regression models and find that collaborative Scratch projects tend to receive ratings that are lower than individually authored works. We also find that code-intensive collaborations are rated higher than media-intensive efforts. We conclude by discussing the limitations and implications of these findings.

description: Reconstructing the 3D shape of an object from a set of images is a classical problem in Computer Vision. Photometric stereo is one of the possible approaches. It stands on the assumption that the object is observed from a fixed point of view under different lighting conditions. The traditional approach requires that the position of the light sources is accurately known. It has been proved that the lights position can be estimated directly from the data, when at least 6 images of the observed object are available. In this paper, we give a Matlab implementation of the algorithm for solving the photometric stereo problem under unknown lighting, and propose a simple shooting technique to solve the bas-relief ambiguity.

description: Abundant data support a key role for the transcription factor nuclear factor-κB (NF-κB) signaling pathway in controlling the initiation and progression of human cancer. NF-κB and associated regulatory proteins such as IκB kinase (IKK) are activated downstream of many oncoproteins and there is much evidence for the activation of NF-κB-dependent target genes in a variety of solid tumors and hematologic malignancies. This review focuses on the mechanisms by which the NF-κB pathway is activated in cancer and on the oncogenic functions controlled by activated NF-κB. Additionally, the effects of NF-κB activation in tumors relative to cancer therapy are also discussed.

Tardigrades Use Intrinsically Disordered Proteins to Survive Desiccation
Creators: name: Boothby, Thomas C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Tardigrades are microscopic animals that survive a remarkable array of stresses, including desiccation. How tardigrades survive desiccation has remained a mystery for more than 250 years. Trehalose, a disaccharide essential for several organisms to survive drying, is detected at low levels or not at all in some tardigrade species, indicating that tardigrades possess potentially novel mechanisms for surviving desiccation. Here we show that tardigrade-specific intrinsically disordered proteins (TDPs) are essential for desiccation tolerance. TDP genes are constitutively expressed at high levels or induced during desiccation in multiple tardigrade species. TDPs are required for tardigrade desiccation tolerance, and these genes are sufficient to increase desiccation tolerance when expressed in heterologous systems. TDPs form non-crystalline amorphous solids (vitrify) upon desiccation, and this vitrified state mirrors their protective capabilities. Our study identifies TDPs as functional mediators of tardigrade desiccation tolerance, expanding our knowledge of the roles and diversity of disordered proteins involved in stress tolerance.

La courbe maîtresse de l’angle de phase des bitumes s’est avérée très sensible au vieillissement et des méthodes statistiques multivariées ont été utilisées pour exploiter son potentiel. En revisitant la δ-méthode, les résultats de ces analyses statistiques ont permis de proposer un nouvel indice qui quantifie l’incidence des agglomérations moléculaires à travers la rhéologie des bitumes. De plus, des corrélations satisfaisantes avec la performance des enrobés à basse température sont observées.

description: We report extremely large magnetoresistance (MR) in an extended temperature regime from 1.5 K to 300 K in non-magnetic binary compounds TaP and NbP. TaP exhibits linear MR around $1.8\times 10^4$ at 2 K in a magnetic field of 9 Tesla, which further follows its linearity up to $1.4\times 10^5$ in a magnetic field of 56 Tesla at 1.5 K. At room temperature the MR for TaP and NbP follows a power law of the exponent about $1.5$ with the values larger than $300\%$ in a magnetic field of 9 Tesla. Such large MR in a wide temperature regime is not likely only due to a resonance of the electron-hole balance, but indicates a complicated mechanism underneath.

description: The Euclidean scattering transform was introduced nearly a decade ago to improve the mathematical understanding of convolutional neural networks. Inspired by recent interest in geometric deep learning, which aims to generalize convolutional neural networks to manifold and graph-structured domains, we define a geometric scattering transform on manifolds. Similar to the Euclidean scattering transform, the geometric scattering transform is based on a cascade of wavelet filters and pointwise nonlinearities. It is invariant to local isometries and stable to certain types of diffeomorphisms. Empirical results demonstrate its utility on several geometric learning tasks. Our results generalize the deformation stability and local translation invariance of Euclidean scattering, and demonstrate the importance of linking the used filter structures to the underlying geometry of the data.

description: Given a connected region in two-dimensional space where events of a certain kind occur according to a certain time-varying density, we consider the problem of setting up a network of autonomous mobile agents to detect the occurrence of those events and possibly record them in as effective a manner as possible. We assume that agents can communicate with one another wirelessly within a fixed communication radius, and moreover that initially no agent has any information regarding the event density. We introduce a new distributed algorithm for agent control based on the notion of an execution mode, which essentially lets each agent roam the target region either at random or following its local view of a density-dependent gradient. Agents can switch back and forth between the two modes, and the precise manner of such changes depends on the setting of various parameters that can be adjusted as a function of the application at hand. We provide simulation results on some synthetic applications especially designed to highlight the algorithm's behavior relative to the possible execution modes.
Viabilité mécanique et écologique d’un liant géopolymère avec des sédiments de dragage non traités

description: Les recherches menées ces dernières années autour de l’utilisation des sédiments de dragage dans la fabrication de béton mettent en avant cette solution pour réduire les coûts et l'impact environnemental du génie civil. Parmi les voies de valorisation innovantes, l’utilisation de la fraction fine des sédiments dans le procédé de géopolymérisation émerge comme un sujet d’intérêt. Cependant, plusieurs verrous sont à lever avant l’implémentation de cette nouvelle famille de matériaux. Ainsi, cette étude vise à répondre aux problématiques soulevées lors de l’utilisation de sédiment de dragage dans les travaux publics notamment à travers la valorisation de sédiments non-traités dans une matrice géopolymère tout en quantifiant l’analyse de cycle de vie d’un tel procédé. Dans cette étude, plusieurs formulations ont été testées en combinant les sédiments de dragage non traités du Grand Port Maritime de Bordeaux (GPMB) avec des réactifs alcalins et des matériaux cimentaires/additions complémentaires. Les résultats montrent la possibilité d’atteindre des résistances mécaniques à la compression allant jusqu’à 7 MPa et un impact carbone moins élevé mettant en avant le potentiel de la géopolymérisation.

description: This paper introduces design explorations in neighborhood collaborative storytelling. We focus on blogs and citizen journalism, which have been celebrated as a means to meet the reporting needs of small local communities. These bloggers have limited capacity and social media feeds seldom have the context or readability of news stories. We present NewsPad, a content editor that helps communities create structured stories, collaborate in real time, recruit contributors, and syndicate the editing process. We evaluate NewsPad in four pilot deployments and find that the design elicits collaborative story creation.

description: We introduce a mixed integer program (MIP) for assigning importance scores to each neuron in deep neural network architectures which is guided by the impact of their simultaneous pruning on the main learning task of the network. By carefully devising the objective function of the MIP, we drive the solver to minimize the number of critical neurons (i.e., with high importance score) that need to be kept for maintaining the overall accuracy of the trained neural network. Further, the proposed formulation generalizes the recently considered lottery ticket optimization by identifying multiple "lucky" sub-networks resulting in optimized architecture that not only performs well on a single dataset, but also generalizes across multiple ones upon retraining of network weights. Finally, we present a scalable implementation of our method by decoupling the importance scores across layers using auxiliary networks. We demonstrate the ability of our formulation to prune neural networks with marginal loss in accuracy and generalizability on popular datasets and architectures.

description: Les bâtiments du futur doivent répondre à des exigences de plus en plus élevées en matière de performances énergétiques et de durabilité environnementale, pour l'ensemble des chaînes de production et construction. Cette question a suscité un vif intérêt vers l’utilisation de matériaux naturels comme la terre crue dans la construction, caractérisée par une intrinsèque disponibilité, durabilité et recyclabilité. En Europe, la diffusion des technologies en terre crue a été entravée par l'absence de législation spécifique réglementant son utilisation à des fins portantes, en particulier dans les territoires à haut risque sismique. La thèse a eu pour objectif la conception d'un type de construction modulaire renforcée en pisé, réalisée avec des matériaux naturels, peu coûteux ou de réemploi. Elle comprenait la conception de mélange de terre adaptée aux applications porteuses, la définition d'une technologie pour les zones à haut risque sismique et l'évaluation des performances thermiques et énergétiques attendues au moyen de simulations numériques calibrées sur une campagne de caractérisation des matériaux. Les principaux résultats des travaux sont présentés et commentés.

description: In the present study we investigate magnetic reconnection in twisted magnetic fluxtubes with different initial configurations. In all considered cases, energy release is triggered by the ideal kink instability, which is itself the result of applying footpoint rotation to an initially potential field. The main goal of this work is to establish the influence of the field topology and various thermodynamic effects on the energy release process. Specifically, we investigate convergence of the magnetic field at the loop footpoints, atmospheric stratification, as well as thermal conduction. In all cases, the application of vortical driving at the footpoints of an initally potential field leads to an internal kink instability. With the exception of the curved loop with high footpoint convergence, the global geometry of the loop change little during the simulation. Footpoint convergence, curvature and atmospheric structure clearly influences the rapidity with which a loop achieves instability as well as the size of the subsequent energy release. Footpoint convergence has a stabilising influence and thus the loop requires more energy for instability, which means that the subsequent relaxation has a larger heating effect. Large-scale curvature has the opposite result: less energy is needed for instability and so the amount of energy released from the field is reduced. Introducing a stratified atmosphere gives rise to decaying wave phenomena during the driving phase, and also results in a loop that is less stable.

description: Generalized Polynomial Chaos (gPC) expansions are well established for forward uncertainty propagation in many application areas. Although the associated computational effort may be reduced in comparison to Monte Carlo techniques, for instance, further convergence acceleration may be important to tackle problems with high parametric sensitivities. In this work, we propose the use of conformal maps to construct a transformed gPC basis, in order to enhance the convergence order. The proposed basis still features orthogonality properties and hence, facilitates the computation of many statistical properties such as sensitivities and moments. The corresponding surrogate models are computed by pseudo-spectral projection using mapped quadrature rules, which leads to an improved cost accuracy ratio. We apply the methodology to Maxwell's source problem with random input data. In particular, numerical results for a parametric finite element model of an optical grating coupler are given.

description: We provide in this paper a first step to obtain the conformal scattering theory for the linearized gravity fields on the Schwarzschild spacetime by using the conformal geometric approach. We will show that the existing decay results for the solutions of the Regge-Wheeler and Zerilli equations obtained recently by L. Anderson, P. Blue and J. Wang \cite{ABlu} is sufficient to obtain the conformal scattering.

description: The counting process with the Cox‐type intensity function has been commonly used to analyse recurrent event data. This model essentially assumes that the underlying counting process is a time‐transformed Poisson process and that the covariates have multiplicative effects on the mean and rate function of the counting process. Recently, Pepe and Cai, and Lawless and co‐workers have proposed semiparametric procedures for making inferences about the mean and rate function of the counting process without the Poisson‐type assumption. In this paper, we provide a rigorous justification of such robust procedures through modern empirical process theory. Furthermore, we present an approach to constructing simultaneous confidence bands for the mean function and describe a class of graphical and numerical techniques for checking the adequacy of the fitted mean–rate model. The advantages of the robust procedures are demonstrated through simulation studies. An illustration with multiple‐infection data taken from a clinical study on chronic granulomatous disease is also provided.
Etude de la carbonatation des matériaux cimentaires à base d’un ciment à fort teneur en laitier de haut fourneau

description: Dans le contexte actuel de volonté de réduction des émissions de Gaz à Effet de Serre, il est essentiel de réduire ceux émis par la production du ciment Portland et surtout du clinker. Pour cela, il est possible de diminuer la proportion de clinker du liant en le remplaçant ou en substituant une partie par des déchets ou des co-produits de l’industrie tel que des laitiers de haut fourneau. Cependant, ces liants doivent présenter de bonnes propriétés mécaniques et une bonne durabilité. En effet, les structures contenant ces ciments peuvent être exposées à l’air ambiant donc à l’humidité, à la carbonatation et simultanément soumises à des contraintes mécaniques. Ces recherches visent à étudier principalement les propriétés de durabilité d’un ciment à très forte teneur en laitier de haut-fourneau (CEM III/C). De plus, l’étude étant inscrite dans le cadre du WG4 du groupe de travail RILEM TC 281-CCC, les effets de la carbonatation sur le comportement mécanique et inversement les effets de la sollicitation mécanique lors du processus de carbonatation accélérée ou naturelle sont étudiés. Différentes concentrations en CO2 (0,04%, 2% et 20%) sont testées. Les résultats ont montré que le chargement mécanique imposé lors des essais de carbonatation a un impact sur la flèche en flexion et sur l'épaisseur carbonatée ainsi que sur la résistance à la flexion. De plus l’humidité relative a également un très fort impact sur ce ciment.

Méthodologie pour l’évaluation du coefficient de diffusion des chlorures dans le béton armé sous chargement de traction
Creators: name: Asselin, Amandine
Publisher: name: Academic Journal of Civil Engineering
Year: 2023

description: L’exposition à un environnement marin ou à des sels de déverglaçage est à l’origine de phénomènes de corrosion des armatures dans les structures en béton armé : les chargements mécanique, thermique et/ou hydrique entraînent effectivement la formation de fissures, lesquelles sont alors un chemin privilégié pour la pénétration des chlorures jusqu’aux armatures. La mesure du coefficient de diffusion des chlorures dans le béton est un bon indice de la résistance du béton à cette pénétration. Il est actuellement souvent mesuré sur des bétons sans armature, sains ou dans une condition fissurée après déchargement. Or, les structures comportent des armatures et sont en réalité soumises à des chargements conduisant à la création de fissures même en conditions de service en règle générale. Afin de rendre compte de l’impact de ces conditions sur la mesure du coefficient de diffusion, un protocole expérimental a été développé : le coefficient de diffusion est mesuré pendant un essai de migration sous champ électrique en régime permanent dans un tirant en béton armé maintenu sous un chargement de traction.

description: Efficient and safe extraction of microRNAs (miRNAs) from biological samples is pivotal for genetic regulation studies and biotechnological applications. This study focuses on optimizing the microRNA extraction process from the plasma of common carp, a significant species in aquaculture. Recognizing the limitations and hazards of commercial extraction kits, which often employ toxic chemicals like phenol and chloroform, we sought to develop a safer and more effective alternative. Our optimized protocol utilizes guanidinium isothiocyanate (GITC) and sarkosyl, omitting hazardous substances. We explored several parameters including GITC concentration, the addition of sarkosyl, and the role of sodium chloride in enhancing miRNA yield. Our findings demonstrate that optimal conditions involve a GITC concentration of 4.2 M, a 3% sarkosyl concentration, and the use of sodium chloride at 0.5 M. We also investigated the utility of glycogen as a nucleic acid carrier, finding 160 µg to be the optimal concentration. Comparative analysis with commercial kits indicated our method provides higher miRNA yields with reduced cycle threshold values, underscoring the effectiveness of our custom protocol. This optimized approach not only enhances miRNA recovery but also emphasizes safety and cost-effectiveness, making it a valuable method for both research and practical applications in aquaculture.
