description: Purpose of Review: Organophosphate esters (OPEs) are applied to a variety of consumer products, primarily as flame retardants and plasticizers. OPEs can leach out of products over time and are consequently prevalent in the environment and frequently detected in human biomonitoring studies. Exposure during pregnancy is of particular concern as OPEs have recently been detected in placental tissues, suggesting they may be transferred to the developing infant. Also, studies have now shown that children typically experience higher exposure to several OPEs compared with adults, indicating they may be disproportionately impacted by these compounds. This review summarizes the current literature on reproductive and child health outcomes of OPE exposures and highlights areas for future research. Recent Findings: Experimental animal studies demonstrate potential for OPEs to adversely impact health, and a limited number of epidemiologic studies conducted in adult cohorts suggest that OPEs may interfere with the endocrine system. Neurodevelopment is perhaps the most well studied of children’s health endpoints, and several studies indicate that prenatal and early life OPE exposures impact both cognitive and behavioral development. Associations have also been reported with reproductive outcomes (e.g., fertilization and pregnancy loss) and with the timing of parturition and preterm birth. Cross-sectional studies also demonstrate associations between OPEs and respiratory health outcomes, allergic disease, and measures of adiposity. Summary: An expanding body of research demonstrates that OPEs are associated with adverse reproductive health and birth outcomes, asthma and allergic disease, early growth and adiposity, and neurodevelopment. Still, additional research is urgently needed to elucidate the full impact of OPEs on children’s health.

description: OH231.8+4.2 is a well studied O-rich CSE around an intermediate-mass evolved star that displays bipolar molecular outflows accelerated up to 400 km/s. OH231 also presents an exceptional molecular richness probably due to shock-induced chemical processes. We report the first detection in this source of HNCO, HNCS, HC3N and NO, with the IRAM-30m telescope in a sensitive mm-wavelength survey towards this target. HNCO and HNCS are also first detections in CSEs. The observed line profiles show that the emission arises in the massive central component of the envelope and at the base of the fast lobes. The NO profiles are broader than those of HNCO, HNCS, and HC3N, and most importantly, broader than the line profiles of 13CO. This indicates that the NO abundance is enhanced in the fast lobes relative to the slow, central parts. From LTE and non-LTE excitation analysis, we estimate beam-average rotational temperatures of 15-30 K (and, maybe, up to 55 K for HC3N) and fractional abundances of X(HNCO)=[0.8-1]E-7, X(HNCS)=[0.9-1]E-8, X(HC3N)=[5-7]E-9 and X(NO)=[1-2]E-6. NO is, therefore, amongst the most abundant N-bearing species in OH231. We have performed thermodynamical chemical equilibrium and chemical kinetics models to investigate the formation of these N-bearing species in OH231. The model underestimates the observed abundances for HNCO, HNCS, and HC3N by several orders of magnitude, which indicates that these molecules can hardly be products of standard UV-photon and/or cosmic-ray induced chemistry in OH231, and that other processes (e.g. shocks) play a major role in their formation. For NO, the model abundance is compatible with the observed average value. The new detections presented in this work corroborate the particularly rich chemistry of OH231, which is likely profoundly influenced by shock-induced processes, as proposed in earlier works.

description: We have in mind a register of qubits for an quantum information system, and consider its decoherence in an idealized but typical situation. Spontaneous decay and other couplings to the far environment considered as the world outside the quantum apparatus will be neglected, while couplings to quantum states within the apparatus, i.e. to a near environment are assumed to dominate. Thus the central system couples to the near environment which in turn couples to a far environment. Considering that the dynamics in the near environment is not sufficiently well known or controllable, we shall use random matrix methods to obtain analytic results. We consider a simplified situation where the central system suffers weak dephasing from the near environment, which in turn is coupled randomly to the far environment. We find the anti-intuitive result that increasing the coupling between near and far environment actually protects the central qubit.

description: The variant of Fedosov construction based on fairly general fiberwise product in the Weyl bundle is studied. We analyze generalized star products of functions, of sections of endomorphisms bundle, and those generating deformed bimodule structure as introduced previously by Waldmann. Isomorphisms of generalized Fedosov algebras are considered and their relevance for deriving Seiberg-Witten map is described. The existence of the trace functional is established. For star products and for the trace functional explicit expressions, up to second power of deformation parameter, are given. The example of symmetric part of noncommutativity tensor is discussed as a case with possible field-theoretic application.

description: Several experiments have shown qubit coherence decay of the form $\mathrm{exp}[-(t/T_2)^α]$ due to environmental charge-noise fluctuations. We present a microscopic description for temperature dependences of the parameters $T_2$ and $α$. Our description is appropriate to qubits in semiconductors interacting with spurious two-level charge fluctuators coupled to a thermal bath. We find distinct power-law dependences of $T_2$ and $α$ on temperature depending on the nature of the interaction of the fluctuators with the associated bath. We consider fluctuator dynamics induced by first- and second-order tunneling with a continuum of delocalized electron states. We also study one- and two-phonon processes for fluctuators in either GaAs or Si. These results can be used to identify dominant charge-dephasing mechanisms and suppress them.

description: We show that by appealing to a Quark-Nova (the explosive transition of a neutron star to a quark star) occurring in an He-HMXB system we can account for the lightcurve of the first superluminous SN, DES13S2cmm, discovered by the Dark-Energy Survey. The neutron star's explosive conversion is triggered as a result of accretion during the He-HMXB second Common Envelope phase. The dense, relativistic, Quark-Nova ejecta in turn energizes the extended He-rich Common Envelope in an inside-out shock heating process. We find an excellent fit (reduced chi^2 of 1.09) to the bolometric light-curve of SN DES13S2cmm including the late time emission, which we attribute to Black Hole accretion following the conversion of the Quark Star to a Black hole.

description: The problem of surface moisture and condensation inside microstructures is complex and depends on the physicochemical characteristics of both the atmosphere and the surfaces. The relative humidity within a pore is a function of the temperature, mixing ratio, pore geometry, and presence and nature of soluble salts and can be considerably pores types as well as on atmospheric relative humidity. However, although the phenomenon of capillary condensation or evaporation is a complicated process, it would be useful to introduce a critical relative humidity and temperature in micropores structures. To examine the mechanisms of condensation and evaporation of water in micropore structures, we report the critical relative humidity in the capillary pores, cylindrical and square types and as well as dependency of the critical relative humidity on temperature and various contact angles.

description: Insufficient vitamin D during pregnancy increases risk of adverse outcomes, with known differences by race/ethnicity. We sought to determine whether predictors of vitamin D insufficiency vary by race/ethnicity in an ethnically diverse pregnancy cohort. Plasma 25-hydroxyvitamin D concentrations and patient characteristics were measured at first prenatal visit to prenatal clinics in south-eastern USA between 2009 and 2011 (n 504). Prevalence ratios (PR) and 95 % CI were estimated using multivariable regression to quantify predictors of vitamin D insufficiency, overall and by race/ethnicity. In race/ethnicity-stratified models, season was most associated with vitamin D insufficiency among non-Hispanic white women; PR for winter v. summer were 3·58 (95 % CI 1·64, 7·81) for non-Hispanic white, 1·52 (95 % CI 1·18, 1·95) for Hispanic and 1·14 (95 % CI 0·99, 1·30) for non-Hispanic black women. Although women with darker skin tones are most vulnerable to prenatal vitamin D insufficiency, season may be more strongly associated with insufficiency among women with lighter skin tones.

description: This work focuses on the electric power market, comparing the status quo with the recent trend towards the increase in distributed self-generation capabilities by prosumers. Starting from the existing tension between the intrinsically hierarchical current structure of the electricity distribution network and the substantially distributed and self-organising nature of the self-generation, we explore the limitations imposed by the current conditions. Initially, we introduce a potential multi-layered architecture for a Peer-to-Peer (P2P) energy market, discussing thefundamental aspects of local production and local consumption as part of a microgrid. Secondly, we analyse the consequent changes for the different users' roles, also in connection withsome incentive models connected with the decentralisation of the power production. To give a full picture to the reader, we also scrutinise relevant elements of energy trading, such as Smart Contract and grid stability. Thirdly, we present an example of a typical P2P settlement, showcasing the role of all the previously analysed aspects. To conclude, we performed a review of relevant activities in this domain, to showcase where existing projects are going and what are the most important themes covered. Being this a work in progress, many open questions are still on the table and will be addressed in the next stages of the research. Eventually, by providing a reference model as base for further discussions and improvements, we would like to engage ourselves in a dialog with the different users and the broad community, oriented towards a more fair and ecological-friendly solution for the electricity market of the future.

Publisher: name: Academic Journal of Civil Engineering

description: Une façon simple de caractériser une distribution granulométrique est d’établir sa courbe granulométrique par tamisage. Cependant, lorsque les échantillons sont de très petite taille où qu’une colonne de tamis n’est pas disponible, comme sur un chantier, cette technique n’est plus utilisable. Dans cette étude, des échantillons de sables et d’autres matériaux, naturels ou synthétiques sont utilisés pour tester la robustesse d’une méthode d’analyse d'images basée sur l’utilisation d’un scanner 2D pour reconstruire une distribution granulométrique telle que fournirait une colonne de tamis. L’étude concerne la gamme de 100 µm à 3000 µm. Basé sur l’écart quadratique entre distribution granulométrique par analyse d’images et colonne de tamis, un bon accord est trouvé pour des distributions de sables homogènes, hétérogènes voire bimodaux. Les limites d’application de la technique sont également abordées. Sa facilité de mise en œuvre, sa rapidité et son faible coût, font de la méthode de reconstruction par analyse d’images, une méthode alternative intéressante.

description: Dans l’optique d’une construction plus écologique, les blocs de terre comprimée (BTC) sont de plus en plus recherchés. Ils assurent une économie d’énergie et présentent des avantages par rapport aux autres éléments de maçonnerie (matériaux naturels, réutilisables, etc.). Dans cette étude, des BTC sont fabriqués à base de sédiments de dragage afin d’investiguer la possibilité de leur valorisation dans le domaine des matériaux de construction. Une évaluation non destructive des BTC permet de retrouver de manière qualitative les caractéristiques des blocs sans les endommager. Cette approche peut également être utilisée de manière corrélative afin d'inférer d'autres caractéristiques physiques. La résistivité électrique spectrale des BTC non stabilisés fabriqués à différentes pressions de compactage est mesurée. Le suivi temporel montre l’impact du degré de saturation des blocs sur les mesures. Plusieurs paramètres comme la contrainte de compaction, le séchage et la fréquence du signal peuvent influencer les résultats et des précautions doivent être prises pour éviter toute perturbation due au montage et aux conditions de l’essai.

Elle a pour objectif de montrer l’efficacité de diverses solutions techniques en vue d’aboutir à la massification de leur usage. Les matériaux bio-sourcés s’inscrivent dans ces solutions techniques à travers leurs caractéristiques hygrothermiques contribuant à la performance des enveloppes et au confort des ambiances intérieures. Après avoir observé, compris et mis en valeur les phénomènes liés aux transferts hygrothermiques se produisant dans de tels matériaux, il convient désormais d’offrir aux bureaux d’études des outils pertinents et accessibles pour leur prise en compte précise. Les outils commerciaux s’appuient sur des modèles basiques ne prenant pas en compte les phénomènes complexes des transferts hygriques tels que l’hystérésis ou la cinétique de sorption. Il s’agit ici d’envisager une autre façon d’intégrer ces phénomènes complexes, en ayant recours à une identification des paramètres hygriques à partir de mesures en régime dynamique associées à une méthode inverse. Les paramètres identifiés sont utilisés en entrée d’un code commercial et permettent une très bonne prédiction de la réponse hygrique sur l’épaisseur d’une brique de béton de chanvre sous sollicitation dynamique.

description: We prove a Morse Lemma for coarsely regular quasigeodesics in nonpositively curved symmetric spaces and euclidean buildings X. The main application is a simpler coarse geometric characterization of Morse subgroups of the isometry groups Isom(X) as undistorted subgroups which are coarsely uniformly regular. We show furthermore that they must be word hyperbolic. We introduced this class of discrete subgroups in our earlier paper, in the context of symmetric spaces, where various equivalent geometric and dynamical characterizations of word hyperbolic Morse subgroups were established, including the Anosov subgroup property.

description: Previous studies have shown complications of pregnancy, often examined in aggregate, to be associated with autism spectrum disorder (ASD). Results for specific complications, such as maternal diabetes and hypertension, have not been uniformly consistent and should be investigated independently in relation to ASD in a large community-based sample. The Study to Explore Early Development (SEED), a US multisite case–control study, enrolled children born in 2003–2006 at 2–5 years of age. Children were classified into three groups based on confirmation of ASD (n = 698), non-ASD developmental delay (DD; n = 887), or controls drawn from the general population (POP; n = 979). Diagnoses of any diabetes or hypertensive disorder during pregnancy were identified from prenatal medical records and maternal self-report. Logistic regression models estimated adjusted odds ratios (aOR) and confidence intervals (CI) adjusting for maternal age, race/ethnicity, education, smoking during pregnancy, and study site. Models for hypertension were additionally adjusted for parity and plurality. Among 2,564 mothers, we identified 246 (9.6%) with any diabetes and 386 (15.1%) with any hypertension in pregnancy. After adjustment for covariates, any diabetes during pregnancy was not associated with ASD (aOR = 1.10 [95% CI 0.77, 1.56]), but any hypertension was associated with ASD (aOR = 1.69 [95% CI 1.26, 2.26]). Results were similar for DD, and any diabetes (aOR = 1.29 [95% CI 0.94, 1.78]) or any hypertension (aOR = 1.71 [95% CI 1.30, 2.25]). Some pregnancy complications, such as hypertension, may play a role in autism etiology and can possibly serve as a prompt for more vigilant ASD screening efforts. Autism Res 2019, 12: 967–975. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary: We studied if common complications in pregnancy are associated with autism spectrum disorder (ASD) in a large sample of mothers and children. Our results show an association between conditions marked by high blood pressure and ASD, but no association with conditions marked by high blood sugar and ASD. Associations were similar for children who had a developmental disorder that was not ASD, suggesting that this relationship may not be specific to ASD.
Scalability of asynchronous networks is limited by one-to-one mapping between effective connectivity and correlations

description: Network models are routinely downscaled compared to nature in terms of numbers of nodes or edges because of a lack of computational resources, often without explicit mention of the limitations this entails. While reliable methods have long existed to adjust parameters such that the first-order statistics of network dynamics are conserved, here we show that limitations already arise if also second-order statistics are to be maintained. The temporal structure of pairwise averaged correlations in the activity of recurrent networks is determined by the effective population-level connectivity. We first show that in general the converse is also true and explicitly mention degenerate cases when this one-to-one relationship does not hold. The one-to-one correspondence between effective connectivity and the temporal structure of pairwise averaged correlations implies that network scalings should preserve the effective connectivity if pairwise averaged correlations are to be held constant. Changes in effective connectivity can even push a network from a linearly stable to an unstable, oscillatory regime and vice versa. On this basis, we derive conditions for the preservation of both mean population-averaged activities and pairwise averaged correlations under a change in numbers of neurons or synapses in the asynchronous regime typical of cortical networks. We find that mean activities and correlation structure can be maintained by an appropriate scaling of the synaptic weights, but only over a range of numbers of synapses that is limited by the variance of external inputs to the network. Our results therefore show that the reducibility of asynchronous networks is fundamentally limited.

description: The prevalence of food-borne infections has grown worldwide and is still a significant public health issue. In the current investigation, the incidence of Salmonella spp., Staphylococcus aureus, and Escherichia coli were assessed from fish species Mystus seenghala as well as the antimicrobial susceptibility pattern against eight selected antibiotics. From 100 samples, a total of 53 E. coli bacteria, 37 S. aureus strains, and 10 Salmonella spp. strain were isolated and extensively described using the usual culture method and biochemical testing. The Kirby-Bauer disc diffusion technique was used to screen the isolates for antimicrobial resistance against 8 different antibiotics. According to an antibiogram research, S. aureus isolates had a high resistance to amoxicillin (89.19%), whereas E. coli isolates had a high resistance to cephazolin (68.67%), erythromycin (66.26%), and chloramphenicol (65.06%). Only one positive Salmonella species (2%), resistant to Amoxycillin, Penicillin and Ciprofloxacin, was found in the test. In order to ensure healthy fish, adequate staff hygiene is crucial while processing and handling fish. To prevent the creation of numerous antibiotic resistant types of bacteria, excessive usage of antibiotics should be avoided.

description: Dans le cadre de la construction bas carbone, les matériaux alcali-activés ont suscité un grand intérêt. Ce travail vise à étudier l’effet de l’ajout de laitier de haut fourneau (LHF) avec des grandes proportions sur les propriétés à l’état frais et à l’état durci d’un liant alcali-activé à base de métakaolin (MK) et le silicate de sodium. Puis évaluer l’effet de la température de séchage et le temps de cure sur les propriétés physiques et mécaniques. Les résultats de l’étude à l’état frais ont révélé que l’ajout de LHF a amélioré la réaction d’activation en élevant le flux de chaleur dégagé et en réduisant le temps de prise. A l’état durci, l’incorporation de LHF a montré un effet favorable sur la résistance à la compression grâce à la réactivité élevée du LHF prouvée par la calorimétrie. De plus, l’élévation de la température du séchage à 60°C a provoqué une diminution de la résistance à la compression à 7 et à 28 jours à cause de l’augmentation de la porosité et les fissurations à cette température de séchage.

description: The goal of Intellectual Output 2 of the UPSKILLS project has been to compile and publish a collection of best practices, documenting the steps needed for integrating ongoing research into teaching; not only academic research, but also research done in industry. Since one of the main aims of the UPSKILLS project is to prepare students from language-related study subjects for the job market and several such students will inevitably find jobs in the language industry, the introduction of research projects that are coming from it in upskilled curricula is an important part of our overall vision. This report describes the efforts made to integrate industry-based research into teaching. We present challenges and opportunities from both the perspective of industry and academia, possible formats, the steps we took to implement industry-based research in teaching in the framework of UPSKILLS, and describe successes and challenges we encountered along the way.

One way to access this potential is to apply a strong optical trap to a minimally supported mechanical element, thereby increasing its quality factor $Q_m$. Current schemes, however, require prohibitively high laser power ($\sim10$ W), and the $Q_m$ enhancement is ultimately limited to a factor of $\sim$ 50 by hybridization between the trapped mode and the dissipative modes of the supporting structure. Here we propose a levitation scheme taking full advantage of an optical resonator to reduce the circulating power requirements by many orders of magnitude. Applying this scheme to the case of a dielectric disk in a Fabry-Perot cavity, we find a tilt-based tuning mechanism for optimizing both center-of-mass and torsional mode traps. Notably, the two modes are trapped with comparable efficiency, and we estimate that a 10-micron-diameter, 100-nm-thick Si disc could be trapped to a frequency of $\sim$ 10 MHz with only $30$ mW circulating in a cavity of (modest) finesse 1500. Finally, we simulate the effect such a strong trap would have on a realistic doubly-tethered disc. Of central importance, we find torsional motion is comparatively immune to $Q_m$-limiting hybridization, allowing a $Q_m$ enhancement factor of $\sim$ 1500. This opens the possibility of realizing a laser-tuned 10 MHz mechanical system with a quality factor of order a billion.

description: Most prior studies examining maternal pre-pregnancy body mass index (BMI) in relation to offspring autism spectrum disorders (ASD) have reported an association, though findings are not uniform and few have also examined gestational weight gain (GWG). Therefore, we examined both in the Study to Explore Early Development, a multi-site case–control study of children born in 2003–2006. Children identified from clinics, schools, and birth certificates were enrolled at ages 2–5 year and using standardized developmental evaluations, classified as: ASD, other developmental delays (DD), or population-based controls. Maternal height, weight, and GWG were self-reported during the telephone interview. Three primary weight risk factors were examined: (a) Pre-pregnancy BMI, classified as underweight to obese, (b) GWG continuous and categorized as quintiles, and (c) Institute of Medicine clinical weight-gain recommendations. Odds ratios adjusted (AOR) for sociodemographic and prenatal factors were calculated among term singletons, comparing the ASD (n = 540) or DD (n = 720) groups to the control group (n = 776). The AOR of ASD and maternal obesity was 1.37 (95%CI 0.98–1.92). Associations with higher GWG were stronger (Quintile5 vs. Quintile3 AOR = 1.58, 95%CI 1.08–2.31), and particularly so among overweight/obese women (AOR = 1.90, 95%CI 0.98–3.68). DD was associated with maternal overweight and obesity (obesity AOR = 1.48, 95%CI 1.08–2.02), but not with total GWG or clinical recommendations. High maternal BMI and GWG are risk factors for other pregnancy and child outcomes, and our results suggest they may also represent modifiable risk factors for neurodevelopmental outcomes. Autism Res 2019, 12: 316–327 © 2018 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary: In a large, national study, we found that children with autism were more likely than unaffected children to have mothers with higher weight gain during pregnancy; risk of autism may be even stronger if mothers were also overweight before pregnancy. Children with other developmental delays were more likely to have mothers who were overweight or obese before pregnancy, but not who gained more weight during pregnancy. Overweight and weight gain may represent factors that could be modified.

description: Numerous studies have reported immune system disturbances in individuals with autism and their family members; however, there is considerable variability in findings with respect to the specific immune conditions involved, their timing, and the family members affected and little understanding of variation by autism subphenotype. Using data from the Study to Explore Early Development (SEED), a multi-site case-control study of children born 2003–2006 in the United States, we examined the role of family history of autoimmune diseases, asthma, and allergies in autism spectrum disorder (ASD) as well as other developmental disorders (DD). We investigated maternal immune conditions during the pregnancy period, as well as lifetime history of these conditions in several family members (mother, father, siblings, and study child). Logistic regression analyses included 663 children with ASD, 984 children with DD, and 915 controls ascertained from the general population (POP). Maternal history of eczema/psoriasis and asthma was associated with a 20%–40% increased odds of both ASD and DD. Risk estimates varied by specific ASD subphenotypes in association with these exposures. In addition, children with ASD were more likely to have a history of psoriasis/eczema or allergies than POP controls. No association was observed for paternal history or family history of these immune conditions for either ASD or DD. These data support a link between maternal and child immune conditions and adverse neurodevelopmental outcomes, and further suggest that associations may differ by ASD phenotype of the child. Autism Research 2019, 12: 123–135. © 2018 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary: Using data from a large multi-site study in the US—the Study to Explore Early Development—we found that women with a history of eczema/psoriasis and asthma are more likely to have children with ASD or DD. In addition, children with ASD are more likely to have a history of psoriasis/eczema or allergies than typically developing children. These data support a link between maternal and child immune conditions and adverse neurodevelopmental outcomes.

description: The UPSKILLS needs revealed that linguistics and language-related degree programmes seldom include language data standards and research data repositories in their learning outcomes. A survey of lecturers from linguistics and language-related disciplines also exposed a number of challenges in using repositories for language data discovery, reuse and archiving. Against this backdrop, the present guide shows how teachers and trainers can leverage the CLARIN research infrastructure to help students enhance their data collection, processing and analysis, and archiving skills. By integrating research infrastructures into teaching, educators can bridge the gap between theoretical knowledge and practical aspects of linguistic research data management, equipping students with the necessary skills and competences to thrive in the evolving landscape of open science and data-driven research.

description: Dans un contexte environnemental de plus en plus exigeant, le développement de bétons plus respectueux de l’environnement, appelés aussi bétons bas-carbone, et bien évidemment toujours adaptés aux conditions d’exposition des ouvrages, est un enjeu majeur pour les entreprises du BTP. C’est dans ce contexte que la société Menard a réalisé avec le LMDC une étude visant à qualifier de nouveaux bétons pour la réalisation d’une de leur spécificité à savoir les colonnes à module contrôlé. Ces nouveaux bétons ont été développés en se basant sur la méthodologie d’approche performantielle, telle que développée dans le projet national PerfDub et précisée dans le fascicule de documentation FD P 18-480 (2022) et la NF EN 206+A2/CN. L’objectif de cet article est de montrer comment l’approche performantielle permet de qualifier ces bétons bas-carbone destinés à la réalisation de colonnes à module contrôlé, réalisés en centrale, mais aussi les limites actuelles de cette approche performantielle.

description: Oxynitride glasses combine a high refractoriness, with Tg typically >850°C, and remarkable mechanical properties in comparison with their parent oxide glasses. Their Young's modulus and fracture toughness reach 170 GPa and 1.4 MPa m.5, respectively. Most reports show good linear relationships between glass property values and nitrogen content. There is a clear linear dependence of Young's modulus and microhardness on fractional glass compactness (atomic packing density). They also have a better resistance to surface damage induced by indentation or scratch loading. The improvements stem from the increase of the atomic network cross-linking—because of three-fold coordinated nitrogen—and of the atomic packing density, despite nitrogen being lighter than oxygen and the Si–N bond being weaker than the Si–O bond. For constant cation composition, viscosity increases by ∼3 orders of magnitude as ∼17 eq.% oxygen is replaced by nitrogen. For rare earth oxynitride glasses with constant N content, viscosity, Young's modulus, Tg, and other properties increase with increasing cation field strength (decreasing ionic radius). Research continues to find lighter, stiffer materials, including glasses, with superior mechanical properties. With higher elastic moduli, hardness, fracture toughness, strength, surface damage resistance, increased high temperature properties, oxynitride glasses offer advantages over their oxide counterparts

description: Most theoretical tools available for the analysis of spreading processes over networks assume exponentially distributed transmission and recovery times. In practice, the empirical distribution of transmission times for many real spreading processes, such as the spread of web content through the Internet, are far from exponential. To bridge this gap between theory and practice, we propose a methodology to model and analyze spreading processes with arbitrary transmission times using phase-type distributions. Phase-type distributions are a family of distributions that is dense in the set of positive-valued distributions and can be used to approximate any given distributions. To illustrate our methodology, we focus on a popular model of spreading over networks: the susceptible-infected-susceptible (SIS) networked model. In the standard version of this model, individuals informed about a piece of information transmit this piece to its neighbors at an exponential rate. In this paper, we extend this model to the case of transmission rates following a phase-type distribution. Using this extended model, we analyze the dynamics of the spread based on a vectorial representations of phase-type distributions. We illustrate our results by analyzing spreading processes over networks with transmission and recovery rates following a Weibull distribution.

description: The article explores an innovative solution for demountable and reusable composite structures, where concrete panel blocks are bolted to steel beams. Three-point bending tests on these floor systems were studied both experimentally and numerically. Results showed a good agreement between experimental test results and simulations, which allowed validating the numerical model. A parametric analysis was then performed using the numerical model developed. In such parametric study, different concrete inter-blocks spacings were considered. It revealed that a spacing of 0.5 mm between the blocks provides the best match with experimental results. Such analysis also highlighted the fact that concrete interlocks spacing modifies the mechanical behavior of the composite panel floors studied. It thus emphasized the importance of accounting for such parameter when developing composite and demountable steel/concrete floors.
