description: Substrate specificity of SCF E3 ubiquitin ligases is thought to be determined by the F box protein subunit. Another component of SCF complexes is provided by members of the Roc1/Rbx1/Hrt1 gene family, which encode RING-H2 proteins. Drosophila contains three members of this gene family. We show that Roc1a mutant cells fail to proliferate. Further, while the F box protein Slimb is required for Cubitus interruptus (Ci) and Armadillo/beta-catenin (Arm) proteolysis, Roc1a mutant cells hyperaccumulate Ci but not Arm. This suggests that Slimb and Roc1a function in the same SCF complex to target Ci but that a different RING-H2 protein acts with Slimb to target Arm. Consequently, the identity of the Roc subunit may contribute to the selection of substrates by metazoan SCF complexes.
Durabilité de connecteurs collés soumis à des sollicitations de fluage pour des applications sur sous-marins

description: Cold Pad est une PME spécialisée dans le collage structural en milieu offshore qui a développé une solution de connecteur collé permettant de créer de nouveaux points d’ancrage sur une structure. Etant donnée l’utilisation des connecteurs collés, le fluage semble être le phénomène principal à prendre en compte, en termes de durabilité, pour leur conception. L’objectif de cette thèse est de comprendre la phénoménologie du fluage et de déterminer un modèle de fluage indépendant de la géométrie des connecteurs afin de proposer des outils de conception vis-à-vis du fluage. L’étude en fluage est réalisée à deux échelles d’assemblages : celle du joint mince et celle de la structure. Pour analyser le comportement en joints minces en fluage, un bâti de fluage a été développé. Des essais de fluage ont donc été effectués à plusieurs niveaux de chargement et de températures. En amont de la thèse, une campagne d’essais de fluage sur connecteurs collés a été réalisée également à plusieurs niveaux de chargement et de températures. Les résultats de ces deux échelles d’investigations sont ensuite comparés pour choisir la plus pertinent vis-à-vis de l’application industrielle.

description: We have calculated the Casimir-Polder interaction (CPI) of a micro-particle with a sheet on the basis of the Klimchitskaya-Mostepanenko theory. We find the result that for non-trivial susceptibility values of the sheet and micro-particle, there is crossover between attractive and repulsive behavior. The transition depends only on the impedance, involving permeability and permittivity, apart from the ratio of the film thickness and the micro-particle separation (D/d) and temperature. The approach to calculate CPI of a micro-particle with a silicene sheet involves replacing the dielectric constant of the sample by the static dielectric function obtained using the expressions for the polarization function. The silicene is described by the low-energy Liu-Yao-Feng-Ezawa (LYFE)Model Hamiltonian involving the Dirac matrices in the chiral representation obeying the Clifford algebra.We find that the collective charge excitations at zero doping, i.e., intrinsic plasmons, in this system, are absent in the Dirac limit. The valley-spin-split intrinsic plasmons, however, come into being in the case of the massive Dirac particles with characteristic frequency close to 10 THz.Furthermore, there is a longitudinal electric field induced topological insulator(TI) to spin-valley polarized metal (SVPM) transition in silicene, which is also referred to as the topological phase transition (TPT). The low-energy SVP carriers at TPT possess gap-less (mass-less) and gapped (massive) energy spectra close to the two nodal points in the Brillouin zone with maximum spin-polarization. We find that the magnitude of the Casimir-Polder force at a given ratio of the film thickness and the separation between the micro-particle and the film is greater at TPT than at the topological insulator and trivial insulator phases.

Critère pratique pour identifier la rupture d’un monopieu rigide chargé latéralement

description: Les éoliennes offshores constituent l’une des principales solutions adoptées pour répondre au besoin d’énergies décarbonées. Pour des raisons économiques et pratiques, les monopieux sont couramment utilisés comme fondation de ces structures. L’augmentation des dimensions des éoliennes impose un changement de la forme et des propriétés de ces fondations, qui évoluent vers un élancement plus petit et donc un comportement plus rigide. Actuellement, une bonne compréhension des comportements monotone et cyclique de ce type de fondation et le développement d’une méthode de conception conservative et raisonnable restent des enjeux majeurs. Une des méthodes prometteuses concerne l’identification de lois empiriques capables de prévoir la réponse cyclique en fonction du nombre de cycles et des caractéristiques du chargement. Le niveau du chargement est normalisé par rapport à la capacité ultime du monopieu sous chargement monotone, qui dépend du critère de rupture adopté. La fiabilité de la généralisation de ces lois dépend donc de l’aptitude du critère de rupture utilisé à assurer une évaluation satisfaisante de la capacité ultime des monopieux. Dans cette communication, les aptitudes des critères de rupture conventionnels sont discutées et un nouveau critère pratique est proposé et validé.

description: Remark: Challenge withdrawn from MICCAI 2020 due to COVID - 19 pandemic situation.  This is the challenge design document for the "Automatic Structure Segmentation for Radiotherapy Planning Challenge 2020", accepted for MICCAI 2020. We propose to hold the challenge of automatic structure segmentation for radiotherapy planning 2020 in conjunct with MICCAI 2020. We will provide data of two types of cancers, nasopharyngeal cancer and lung cancer. Four challenge tasks will be organized, including Organ-at-risk segmentation from head and neck CT scans, Organ-at-risk segmentation from chest CT scans, Gross Target Volume segmentation of nasopharynx cancer, Gross Target Volume segmentation of lung cancer. A total of 120 CT scans with more than 1520 organ or tumor annotations will be provided in the chanllenge. Radiation therapy is one type of important cancer treatment for killing cancer cells with external beam radiation. Treatment planning is vital for the treatment, which sets up the radiation dose distribution for tumor and ordinary organs. The goal of planning is to ensure the cancer cells receiving enough radiation and to prevent normal cells in organs-at-risk (OAR) from being damaged too much. Organs-at-risk are usually the organs that are sensitive to radiation. For instance, optical nerves and chiasma in the head cannot receive too much radiation otherwise the patient risks losing his/her vision. Gross Target Volume (GTV) is the position and extent of gross tumor imaged by CT scanes, i.e. what can be seen. One important step in radiotherapy treatment planning is therefore to delineate the boundaries of tens of OARs and GTV in every slice of a patient’s CT scans, which is tedious and occupies much of oncologists’ time. Automatic OAR & GTV delineation would substantially reduce the treatment planning time and therefore reduces the overall cost for radiotherapy. This is a re-holding of the successful StructSeg 2019 challenge with 20% more training data on GTV segmentation provided to the research community. In StructSeg 2019, 718 teams have registered and 34 teams submitted their final models for evaluation. The challenge talks and ceremony have attracted a large number of audience to learn about the top-ranking methods during MICCAI 2019. By releasing the new training data, continuely running the online evaluation server, holding the challenge talks, the StructSeg 2020 is expected to continually attract much attention from the research community and advance the research on OAR and GTV segmentation significantly.

description: The ARGO-YBJ experiment is a full-coverage air shower detector located at the Yangbajing Cosmic Ray Observatory (Tibet, People's Republic of China, 4300 m a.s.l.). The high altitude, combined with the full-coverage technique, allows the detection of extensive air showers in a wide energy range and offer the possibility of measuring the cosmic ray proton plus helium spectrum down to the TeV region, where direct balloon/space-borne measurements are available. The detector has been in stable data taking in its full configuration from November 2007 to February 2013. In this paper the measurement of the cosmic ray proton plus helium energy spectrum is presented in the region 3-300 TeV by analyzing the full collected data sample. The resulting spectral index is $γ= -2.64 \pm 0.01$. These results demonstrate the possibility of performing an accurate measurement of the spectrum of light elements with a ground based air shower detector.

description: In this work, we present a family of architectures for polar decoders using a reduced-complexity successive-cancellation decoding algorithm that employs unrolling to achieve extremely high throughput values while retaining moderate implementation complexity. The resulting fully-unrolled, deeply-pipelined architecture is capable of achieving a coded throughput in excess of 1 Tbps on a 65 nm ASIC at 500 MHz---three orders of magnitude greater than current state-of-the-art polar decoders. However, unrolled decoders are built for a specific, fixed code. Therefore we also present a new method to enable the use of multiple code lengths and rates in a fully-unrolled polar decoder architecture. This method leads to a length- and rate-flexible decoder while retaining the very high speed typical to unrolled decoders. The resulting decoders can decode a master polar code of a given rate and length, and several shorter codes of different rates and lengths. We present results for two versions of a multi-mode decoder supporting eight and ten different polar codes, respectively. Both are capable of a peak throughput of 25.6 Gbps. For each decoder, the energy efficiency for the longest supported polar code is shown to be of 14.8 pJ/bit at 250 MHz and of 8.8 pJ/bit at 500 MHz.

description: Polymorphic differences altering expression of genes without changing their products probably underlie human quantitative traits affecting risks of serious diseases, but methods for investigating such quantitative differences in animals are limited. Accordingly, we have developed a procedure for changing the expression in mice of chosen genes over a 100-fold range while retaining their chromosomal location and transcriptional controls. To develop the procedure, we first dissected the effects in embryonic stem (ES) cells of elements within and downstream of the 3' untranslated region (UTR) of a single copy transgene at the Hprt locus. As expected, protein expression varied with the steady-state level and half-life of the mRNA. The rank order of expression with various tested 3' regions is the same in ES cells, and in cardiomyocytes and trophoblastocytes derived from them. In mice having two functionally different native genes with modified 3'UTRs, the desired expression was obtained.

description: In an introductory course on dynamical systems or Hamiltonian mechanics, vector field diagrams are a central tool to show a system's qualitative behaviour in a certain domain. Because of their low sampling rates and the involved issues of vector normalization, these plots give only a coarse insight and are unable to convey the vector field behaviour at locations with high variation, in particular in the neighborhood of critical points. Similarly, automatic generation of phase portraits based on traditional sampling cannot precisely capture separatrices or limit cylces. In this paper, we present ASysViewer, an application for the interactive visual exploration of two-dimensional autonomous dynamical systems using line integral convolution techniques for visualization, and grid-based techniques to extract critical points and separatrices. ASysViewer is addressed to undergraduate students during their first course in dynamical systems or Hamiltonian mechanics.

Performance indicator for cementitious materials exposed to sewer conditions

description: La biodétérioration des matériaux cimentaires dans les réseaux d’assainissement est principalement due à l'oxydation biologique de H2S en H2SO4 conduisant à une dissolution locale et progressive de la matrice cimentaire ainsi qu’à la précipitation de produits expansifs susceptibles de provoquer des fissurations. Dans la littérature, il est largement établi que le ciment d'aluminates de calcium (CAC) a une meilleure résistance dans de tels environnements en comparaison avec le ciment Portland (PC). Les meilleures performances du CAC sont principalement attribuées à la forte teneur en aluminium de ce matériau et aux propriétés physico-chimiques de la matrice cimentaire (phases minéralogiques, porosité, etc.). Dans ce travail, différents matériaux cimentaires à base de ciment Portland, de ciment alumineux, de clinker sulfoalumineux et de laitier alcali-activé ont été exposés à un test accéléré (BAC test) pour reproduire les détériorations observées dans les réseaux d’assainissement. Un indicateur de performance (PIeqOH) a été développé par l’évaluation de la lixiviation des éléments/composés chimiques (notamment le calcium, l’aluminium, le fer, le magnésium et le sulfate, qui définissent le pouvoir tampon des matériaux). Cet indicateur a permis d’établir un classement des matériaux selon leurs résistances à l’attaque d’acide sulfurique biologique dans ces conditions. La meilleure performance a été attribuée au ciment alumineux, suivi par le clinker sulfoalumineux, les ciments à base de Portland et finalement le laitier alcali-activé.

description: Outside cells of the preimplantation mouse embryo form the trophectoderm (TE), a process requiring the transcription factor Tead4. Here, we show that transcriptionally active Tead4 can induce Cdx2 and other trophoblast genes in parallel in embryonic stem cells. In embryos, the Tead4 coactivator protein Yap localizes to nuclei of outside cells, and modulation of Tead4 or Yap activity leads to changes in Cdx2 expression. In inside cells, Yap is phosphorylated and cytoplasmic, and this involves the Hippo signaling pathway component Lats. We propose that active Tead4 promotes TE development in outside cells, whereas Tead4 activity is suppressed in inside cells by cell contact- and Lats-mediated inhibition of nuclear Yap localization. Thus, differential signaling between inside and outside cell populations leads to changes in cell fate specification during TE formation.

description: TThis study examined the antecedent determinants of purchase intentions of minimally processed fresh cut products. In order to gain this purpose we developed a field study that involved 425 consumers. Questionnaires were administered in Italy on a Likert scale. Questions were focused on intentions to purchase fresh cut lamb’s lettuce from environmentally sustainable farms, and with this aim we simulated a fresh cut product with an Eco-label. Using Structural Equation Modelling for data analysis, we proposed the approach that sets out two different types of antecedent determinants: health and green consciousness. Managerial implications are proposed to assess how much the consumer’s green consciousness affects the attitude and the consequent behavior. Some considerations on managerial implications for new marketing strategies for minimally processed food products are proposed, high-lighting the opportunity to take advantage via the potential adoption of an Eco-label.

description: Les bétons peuvent être exposés à une attaque magnésienne dans plusieurs environnements conduisant à la formation de silicate de magnésium hydratés (M-S-H) et de brucite (MH). La formation de M-S-H est susceptible d'altérer les propriétés de la matrice cimentaire car elle est liée à la décalcification du C-S-H. Cependant, relativement peu de données existent sur les M-S-H dans la littérature. Avec l’émergence de nouveaux liants, la composition minéralogique des bétons change et les mécanismes d’altération en présence de magnésium sont donc susceptibles d’être différents de ceux rencontrés dans des ciments ordinaires riches en portlandite. Afin de caractériser les conséquences de l’attaque magnésienne sur de tels liants, une pâte cimentaire modèle, avec un faible rapport Ca/Si, a été fabriquée et immergée dans des solutions magnésiennes à deux concentrations de MgCl2 (5 et 50 mM). Une analyse EDS couplée à de la microsonde et de la DRX montre un enrichissement en Mg de la pâte se traduisant par la formation de M-S-H, associé à une décalcification et une lixiviation en soufre. La zone enrichie en Mg possède des propriétés microstructurales similaires à celles déterminées précédemment sur des pâtes de M-S-H pures et montre un module de Young résiduel plus faible.

description: The role of parents in early childhood special education is critical and highly discussed among researchers. Parental involvement is a fundamental factor in preschoolers’ education and their overall development. However, parental involvement of preschoolers with disabilities is still not fully discussed in Saudi Arabian research. This qualitative study Preschool Teachers’ Perceptions of Parental Involvement of Students with Disabilities in Saudi Arabia . Five research questions were developed to explore teachers’ perceptions regarding the ways of parental involvement, barriers, and solutions to improve parental involvement in preschool. The theoretical framework for this study was Epstein’s model of parental involvement. The data were collected from 20 teachers to be interviewed, the participant were 10 general education teachers and 10 special education teachers sampled from five different schools in the current academic year in Tabuk City, Saudi Arabia. The data were then analyzed and categorized into five main themes (a) teacher’s and parent’s roles and responsibilities, (b) ways of building effective parental involvement, (c) differences in parental involvement between parents of students with and without disabilities, (d) barriers to parental involvement, and (e) changes to improve parental involvement. The findings indicate that teachers and parents have critical duties and responsibilities to ensure parental involvement is active in preschools. The study also emphasized the benefits of parental involvement including setting a firm foundation for students’ educational achievement and enhancing collaboration between teachers and parents. The study highlighted barriers to parental involvement included teachers’ and parents’ lack of disability awareness and parents’ lack of resources. The result showed viable changes to improve parental involvement including creating awareness and sharing parental involvement expectations and improving university teacher preparation programs to include topics of parental involvement. The findings also suggested that the school represented by the administration staff role is very important to promote an effective parental involvement by organizing conferences meetings, seminars, and development programs for in-service teachers. The study also found that there is a need to develop an awareness of disability and special education to parents and general education teachers . Based on the study findings, several recommendations for future research are discussed.

description: Peer review is a quality control mechanism in scholarly research. Most usage refers to a process in which after a paper has been submitted to a journal - an editor of that journal invites independent (external) experts to evaluate that work and provide advice on how the paper could be improved before it is published and shared with the world. However, studies have shown that reviewers fail to detect scientific misconduct, undeclared conflicts of interests, questionable research practices, (significant) methodological deficiencies of papers, spin in results interpretation and generalizability, and transparent reporting needed to assess studies’ risk of bias or quality. Furthermore, peer review has been criticized for scepticism toward innovative research, gender and country bias, low inter-rater agreement between reviewers, long delays it imposes between study submission and publication, and a lack of (certified) reviewer training programs or structured formats that could (perhaps) help reviewers produce reports of better (or sufficient) quality. In this talk I reported on the meta-research on peer review and provided some recommendations for its improvement.

Concrete drying kinetics: development of an accelerated drying protocol in fire testing
Creators: name: SAYARI, Takwa
Publisher: name: Academic Journal of Civil Engineering
Year: 2022

description: This work proposes an accelerated drying protocol that allows reaching a hydric and mechanical state representative of normal service conditions while optimizing the storage time of the specimen before the fire resistance test. The temperature and relative humidity conditions are chosen in a range where microstructure changes are insignificant. An extensive experimental campaign on four concrete formulations is performed, including drying experiments (ambient and accelerated) and fire tests with different durations depending on the type of storage (normalized vs. accelerated drying). Then, the accelerated protocol is proposed based on the modeling of drying at moderate temperature. According to the predictive study, the target moisture content could be achieved under several drying conditions, showing that ad hoc solutions can be proposed. The reproducibility of the accelerated drying protocol is essential to ensure widespread application in research and industrial laboratories. This article focuses on the assessment of the water status.

Coulis alcali-activés: Structuration au jeune âge et à long terme et identification des phases formées

Year: 2022

description: Les matériaux alcali-activés apparaissent comme une solution complémentaire aux liants hydrauliques dans plusieurs applications en génie civil, pour répondre à des enjeux techniques et environnementaux. Néanmoins, ces matériaux n’ont pas été suffisamment explorés, comme coulis d’injection, dans le domaine du renforcement des sols. On constate en effet un déficit de connaissances sur la structuration à court terme et l’évolution chimique et mécanique de ces systèmes relativement dilués. Ce travail vise à investiguer les mécanismes réactionnels et la microstructure de trois familles de matériaux activés. Ces matériaux seront caractérisés à différents échelles au moyen de techniques avancées et d’approches originales. Au cours de la structuration du matériau frais, la mise en relation des propriétés viscoélastiques et physico-chimiques permet d’étudier les liens entre les réactions chimiques et le développement des propriétés mécaniques. A l’état durci, le recours à la résonnance magnétique nucléaire (RMN) permet d’identifier la nature des phases formées au cours de l’activation.

description: L’introduction des fibres d’Alfa dans une matrice cimentaire conduit à l’amélioration des propriétés mécaniques du composite, et en particulier sa résistance en flexion. Cependant, il a été souligné une dégradation des fibres d’Alfa au fil du temps due à la forte alcalinité du milieu cimentaire. Cette étude vise à étudier l’effet des traitements des fibres d’Alfa sur les performances mécaniques et d’adhésion du composite cimentaire. Cinq traitements ont été retenus : traitements chimiques (alcalin et hydrothermal), biologique (enzymatique), physique (ultrasons) et par enrobage minéral (ciment sulfo-alumineux). Les fibres d'Alfa brutes et traitées ont été incorporées dans des mortiers de ciment à différentes longueurs (10 et 20 mm) avec un taux d'addition de 1 %vol. Il a été constaté que les traitements des fibres d’Alfa ont pu améliorer les propriétés mécaniques du composite à long terme. Bien que les traitements les plus efficaces soient les traitements alcalin et hydrothermal, l’ensemble des traitements a fourni une protection de la fibre, améliorant les propriétés des composites à 90 jours. Afin de mesurer les interactions (contrainte de cisaillement) entre la fibre d’Alfa et le mortier de ciment, un dispositif de mesure spécifique basé sur une fibre immergée dans le mortier a été mis en place. Une augmentation des contraintes de cisaillement des fibres après traitement a été notée, ce qui suggère une amélioration des propriétés d’adhésion fibre/mortier.

description: Les mousses minérales constituent une alternative intéressante pour obtenir des produits constructifs allégés et isolants. Cinq tensioactifs (synthétiques et protéiniques) sont sélectionnés pour ce travail de thèse. Leur capacité à réduire la tension de surface et à produire des mousses aqueuses stables a été évaluée. Une classification des tensioactifs est proposée afin de comparer leur pouvoir moussant et leur stabilité. Les mousses minérales sont produites à base de gypse par moussage direct ou par pré-moussage en faisant varier le temps de malaxage, le type de tensioactif, le dosage et le taux de gâchage. Une modélisation considérant une mousse minérale comme un mélange d’une mousse aqueuse et d’une suspension concentrée est proposée. Elle permet d’interpréter les pertes de stabilité constatées ainsi que les réponses rhéologiques des mousses à l’état frais. Ces mousses sont caractérisées à l’état durci en distinguant les contributions des porosités associées aux bulles et à la matrice. Les performances thermiques, mécaniques, hygriques et les perméabilités à l’air et à la vapeur d’eau des mousses sont évaluées. Les interactions entre la formulation, les conditions de moussage et les propriétés d’usage des mousses sont discutées. Les différents résultats obtenus permettent d’identifier les meilleurs compromis de production au regard de performances ciblées.

description: We investigate the intergenerational shape dynamics of single Caulobacter crescentus cells using a novel combination of imaging techniques and theoretical modeling. We determine the dynamics of cell pole-to-pole lengths, cross-sectional widths, and medial curvatures from high accuracy measurements of cell contours. Moreover, these shape parameters are determined for over 250 cells across approximately 10000 total generations, which affords high statistical precision. Our data and model show that constriction is initiated early in the cell cycle and that its dynamics are controlled by the time scale of exponential longitudinal growth. Based on our extensive and detailed growth and contour data, we develop a minimal mechanical model that quantitatively accounts for the cell shape dynamics and suggests that the asymmetric location of the division plane reflects the distinct mechanical properties of the stalked and swarmer poles. Furthermore, we find that the asymmetry in the division plane location is inherited from the previous generation. We interpret these results in terms of the current molecular understanding of shape, growth, and division of C. crescentus
Etude du ressuage des bétons de parois moulées à l’aide d’un essai œdométrique
Creators: name: EL ZEIN, Abdul Rahman
Publisher: name: Academic Journal of Civil Engineering

description: Les parois moulées sont des ouvrages de fondations profondes utilisées afin d’assurer les exigences apportées par les fonctions de soutènement ou de portance. Malgré le respect des règles normatives pour la confection du béton, des pathologies liées au ressuage sont observées. La capacité de rétention d’eau d’un béton de fondation est déterminée à partir des essais spécifiques comme le ressuage statique selon la norme ASTM C232 ou selon l’essai ‘Bauer’ de filtration sous pression. Ces essais permettent de quantifier le taux de ressuage mais n’apportent pas suffisamment de compréhension au niveau des mécanismes des cheminées de remontée d’eau. Une nouvelle approche est proposée, issue de la mécanique des sols, à partir de la théorie de la consolidation unidimensionnelle primaire de Terzaghi. Un nouvel essai basé sur l’essai œdométrique utilisé en mécanique des sols est adapté aux bétons. Afin d’étudier l’influence de la vitesse du coulage d’une paroi moulée sur le ressuage des bétons, deux formulations de bétons N1 et N2 avec différents rapport E/C sont étudiées. Les résultats ont permis de montrer que l’essai œdométrique permet de reproduire le phénomène de ressuage dans une paroi moulée.

A new approach to solving three combinatorial enumeration problems on planar graphs

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: The purpose of this paper is to show how the technique of delta-wye graph reduction provides an alternative method for solving three enumerative function evaluation problems on planar graphs. In particular, it is shown how to compute the number of spanning trees and perfect matchings, and how to evaluate energy in the Ising spin glass model of statistical mechanics. These alternative algorithms require O(n2) arithmetic operations on an n-vertex planar graph, and are relatively easy to implement.

description: We investigate the behaviour of the lowest nonhydrodynamic modes in a class of holographic models which exhibit an equation of state closely mimicking the one determined from lattice QCD. We calculate the lowest quasinormal mode frequencies for a range of scalar self-interaction potentials and find that the damping of the quasinormal modes at the phase transition/crossover falls off by a factor of around two from conformality after factoring out standard conformal temperature dependence. The damping encoded in the imaginary part of the frequencies turns out to be correlated with the speed of sound and is basically independent of the UV details of the model. We also find that the dynamics of the nonhydrodynamic degrees of freedom remains ultralocal, even to a higher degree, as we deviate from conformality. These results indicate that the role of nonhydrodynamic degrees of freedom in the vicinity of the crossover transition may be enhanced.

description: We study three basic diffusion-controlled reaction processes -- annihilation, coalescence, and aggregation. We examine the evolution starting with the most natural inhomogeneous initial configuration where a half-line is uniformly filled by particles, while the complementary half-line is empty. We show that the total number of particles that infiltrate the initially empty half-line is finite and has a stationary distribution. We determine the evolution of the average density from which we derive the average total number N of particles in the initially empty half-line; e.g., for annihilation \langle N\rangle = 3/16+1/(4π). For the coalescence process, we devise a procedure that in principle allows one to compute P(N), the probability to find exactly N particles in the initially empty half-line; we complete the calculations in the first non-trivial case (N=1). As a by-product we derive the distance distribution between the two leading particles.

Two-path subsets: Efficient counting and applications to performability analysis

description: The problem of computing performability probabilities in stochastic PERT and flow networks is studied when the network is minimally designed to withstand any two component failures. Polynomial-time algorithms to compute performability when the network is planar - the nonplanar versions being NP-hard - solve related two-path subset problems. Given an acyclic graph with weights on the arcs, the algorithms compute the total weight of all subsets of arcs that are contained in (1) two source-sink paths, or (2) two are-disjoint source-sink paths. A polynomial algorithm is given for (1), and for (2) in the case where the graph is a source-sink planar k-flow graph, that is, cdge-minimal with respect to supporting k units of flow.
Caractérisation multi-échelle de l’interface entre bétons imprimés : Zone de fragilité.

description: Pour être imprimable, l’encre cimentaire doit avoir des propriétés contradictoires qui, en s’ajoutant à d'autres paramètres d'impression, peuvent avoir une influence sur la tenue mécanique du béton imprimé. Ce travail vise donc à étudier en particulier le lien entre les conditions d’impression et la qualité de la liaison entre les couches. L’étude de l’interface est réalisée à l’aide d’essais d’indentation classique et instrumentée aux échelles micro et macroscopiques, corrélées avec des essais de compression macro multidirectionnels. De plus, un nouveau protocole de préparation des éprouvettes à l’échelle du laboratoire est mis en place, comparables à ceux imprimés manuellement. L’objectif est de caractériser localement le matériau et ses interfaces pour identifier éventuellement des zones de fragilité. Nous proposons alors un critère de fragilité interfaciale établi à partir de profils de dureté mesurés perpendiculairement au plan de l’interface. Ce critère met particulièrement bien en évidence l’influence des conditions d’impression sur la tenue mécanique de l’interface, avec par exemple une dégradation de celle-ci avec une augmentation du temps d’attente. Pour compléter notre analyse, des essais d’indentation dans le plan de l’interface menés jusqu’à rupture confirment une influence des conditions d’impression alors que les essais de compression ne montrent aucune différence.

description: Les enrobés à froid peuvent être une solution pour participer à la décarbonation des routes. La présence d’eau dans le matériau, bénéfique pour sa mise en place, confère au matériau un comportement extrêmement évolutif et dépendant des conditions extérieures. Cet article a pour but de compléter la connaissance des mécanismes régissant cet aspect évolutif, en étudiant l’enrobé, le liant, mais aussi ce qu’il se passe à l’interface entre le liant et le granulat sous différentes conditions extérieures. L’enrobé se rigidifie avec le temps, surtout sous des conditions chaudes et sèches. Cette augmentation de module est due à la rigidification du liant mais aussi à l’évolution de la géométrie des contacts entre le liant et le granulat.

description: We study five problems of finding minimal enclosures comprised of elements of a connected, planar graph with a plane embedding. The first three problems consider the identification of a shortest enclosing walk, cycle or trail surrounding a polygonal, simply connected obstacle on the plane. We propose polynomial algorithms that improve on existing algorithms. The last two problems consider the formation of minimal zones (sets of adjacent regions such that any pair of points in a zone can be connected by a non-zero width curve that lies entirely in the zone). Specifically, we assume that the regions of the graph have nonnegative weights and seek the formation of minimum weight zones containing a set of points or a set of regions. We prove that the last two problems are NP-hard and transform them to Steiner arboresccnce/fixed-charge flow problems.
