This paper presents a multi-scale framework for the failure of periodic quasi-brittle thin planar shells. The failure behavior of textured or periodic heterogeneous materials is strongly influenced by their mesostructure. Their periodicity and the quasi-brittle nature of their constituents result in complex behaviors such as damage-induced anisotropy properties with localization of damage, which are difficult to model by means of macroscopic closed-form constitutive laws. A computational homogenization procedure is used for the in-plane and out-of-plane behavior of such planar shells, and is combined with an acoustic tensor-based failure detection adapted to shell kinematics to detect the structural-scale failure. Based on an assumption of single period failure, the localization of damage at the structural scale is represented by means of mesostructurally informed embedded strong discontinuities incorporated in the macroscopic shell description. A new enhanced scale transition is outlined for shell failure, based on an approximate energy consistency argument to objectively upscale the energy dissipation. The corresponding multi-scale framework results are compared with direct fine-scale modeling results used as a reference for the case of masonry, showing good agreement in terms of the load-bearing capacity, of failure mechanisms and of associated energy dissipation. © 2010 John Wiley & Sons, Ltd.

OBJECTIVE: Telomeres are protected by tightly regulated factors and elongated by telomerase. Short and/or deprotected chromosomes are recombinogenic and thereby cancer prone. MATERIALS AND METHODS: Together with the quantification of telomerase activity (TA), measuring telomere length (TL) and expression of the genes that govern telomere protection and elongation are useful for assessing telomere homeostasis. RESULTS: By these means we demonstrate that TL, hTERT, and TA are in the order acute myelogenous leukemia (AML) > T-cell acute lymphoblastic leukemia (T-ALL) > B-cell acute lymphoblastic leukemia (B-ALL) > T-ALL > AML, and B-ALL > AML > T-ALL. AML0 and AML3 display the lowest amounts of hTERT transcripts, and ALL and AML cells with cytogenetic abnormalities possess the shortest telomeres. hTERT expression includes phenotype-specific RNA maturation and correlates with TA but not with TL. A wide ratio of TA to hTERT expression between leukemia subtypes suggests phenotype-specific hTERT post-transcriptional deregulations. B- and T-ALL overexpress Ku70 and Pinx1, T-ALL PTOP and RAP1, and B-ALL TRF2, the expression of which is significantly higher in cases with abnormal karyotype. hTERT transcription and TL correlate with response to intensive chemotherapy, and hTERT and RAD50 are independent prognostic factors for survival. CONCLUSIONS: Each leukemia subtype possesses specific telomere dysregulations that rely on phenotype, karyotype, response to treatment, and survival. [less ▲]

Le brome épais (Bromus grossus Desf. ex DC.) est une graminée commensale des moissons bien qu'on la trouve occasionnellement en bordure de champs ou dans des terrains en friche. C'est une espèce menacée de disparition dans toute son aire de répartition, raison qui a justifié son inscription à l'annexe II de la Directive 92/43/CEE du Conseil du 21 mai 1992 concernant la conservation des habitats naturels ainsi que de la faune et de la flore sauvages (aussi connue comme la "Directive Habitats"). Cette protection est assurée au niveau wallon par l'inscription de l'espèce à l'annexe VIa du décret du Gouvernement Wallon du 6/12/2001 ; en raison de sa très grande rareté, la Région Wallonne a une responsabilité importante pour sa conservation.

Le diagnostic et la prise en charge thérapeutique du cancer deviennent extrêmement complexes. La concertation oncologique multidisciplinaire (COM) permet d’optimiser la prise en charge du patient atteint de cancer. La COM permet de confronter les différents points de vue de chaque intervenant afin que le plan thérapeutique soit réellement l’approche la plus prometteuse et rationnelle pour traiter le cancer et, dans un contexte de maladie incurable, pour favoriser au mieux la qualité de vie. Cependant, le patient a toujours le dernier mot. Il peut évidemment refuser pour des raisons personnelles le traitement optimal. [less ▲]

A major aim of the Pragmatic Web is “to support communities to put ontologies in context”. As a contribution to this aim, we present the framework we developed to analyze the way we attempted to contextualize the ontologies underlying a set of semantic knowledge services dedicated to communities of practice. The framework was derived from the “Ontology Framework” elaborated by members of the Ontology Engineering community during the Ontology Summit 2007. Both frameworks define a series of “pragmatic dimensions” of ontologies. Because our derived framework does not cover all possible dimensions, we propose to complement it, by relying on existing work from the Ontology Engineering community in general, and from the Pragmatic Web community in particular. In conclusion, we invite the Pragmatic Web community to pursue such a work by jointly elaborating a consensual “Pragmatic Ontology Framework”. [less ▲]

The new 2-phenylthiocarbamoyl-1,3-dimesitylimidazolium inner salt (IMes•CSNPh) reacts with [AuCl(L)] in the presence of NH4PF6 to yield [(L)Au(SCNPh•IMes)]+ (L = PMe3, PPh3, PCy3, CNBut). The carbene-containing precursor [(IDip)AuCl] reacts with IMes•CSNPh under the same conditions to afford the complex [(IDip)Au(SCNPh•IMes)] + (IDip = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene). Treatment of the diphosphine complex [(dppm)(AuCl)2] with one equivalent of IMes•CSNPh yields the digold metallacycle, [(dppm)Au 2(SCNPh•IMes)]2+, while reaction of [L 2(AuCl)2] with two equivalents of IMes•CSNPh results in [(L2){Au(SCNPh•IMes)}2]2+ (L2 = dppb, dppf, or dppa; dppb = 1,4-bis(diphenylphosphino)butane, dppf = 1,1'-bis(diphenylphosphino)ferrocene, dppa = 1,4- bis(diphenylphosphino)acetylene). The homoleptic complex [Au(SCNPh•IMes) 2]+ is formed on reaction of [AuCl(tht)] (tht = tetrahydrothiophene) with two equivalents of the imidazolium-2- phenylthiocarbamoyl ligand. This product reacts with AgOTf to yield the mixed metal compound [AuAg(SCNPh•IMes)2]2+. Over time, the unusual trimetallic complex [Au(AgOTf)2(SCNPh•IMes) 2]+ is formed. The sulfur-oxygen mixed-donor ligands IMes•COS and SIMes•COS (SIMes = 1,3-bis(2,4,6-trimethylphenyl) imidazolin-2-ylidene) were used to prepare [(L)Au(SOC•IMes)]+ and [(L)Au(SOC•SIMes)]+ from [(L)AuCl] (L = PPh3, CNtBu). The bimetallic examples [(dppf){Au(SOC•IMes)} 2]2+ and [(dppf){Au(SOC•SIMes)}2] 2+ were synthesized from the reaction of [(dppf)(AuCl)2] with the appropriate ligand. Reaction of [(tht)AuCl] with one equivalent of IMes•COS or SIMes•COS yields [Au(SOC•IMes) 2]+ and [Au(SOC•SIMes)2]+, respectively. The compounds [(Ph3P)Au(SCNPh•IMes)]PF 6, [(Cy3P)Au(SCNPh•IMes)]PF6 and [Au(AgOTf)2(SCNPh•IMes)2]OTf were characterized crystallographically. [less ▲]

beta-Lactam antibiotics have long been a treatment of choice for bacterial infections since they bind irreversibly to Penicillin-Binding Proteins (PBPs), enzymes that are vital for cell wall biosynthesis. Many pathogens express drug-insensitive PBPs rendering beta-lactams ineffective, revealing a need for new types of PBP inhibitors active against resistant strains. We have identified alkyl boronic acids that are active against pathogens including methicillin-resistant S. aureus (MRSA). The crystal structures of PBP1b complexed to 11 different alkyl boronates demonstrate that in vivo efficacy correlates with the mode of inhibitor side chain binding. Staphylococcal membrane analyses reveal that the most potent alkyl boronate targets PBP1, an autolysis system regulator, and PBP2a, a low beta-lactam affinity enzyme. This work demonstrates the potential of boronate-based PBP inhibitors for circumventing beta-lactam resistance and opens avenues for the development of novel antibiotics that target Gram-positive pathogens.

Quantum cavities or dots have markedly different properties depending on whether their classical counterparts are chaotic or not. Connecting a superconductor to such a cavity leads to notable proximity effects, particularly the appearance, predicted by random matrix theory, of a hard gap in the excitation spectrum of quantum chaotic systems. Andreev billiards are interesting examples of such structures built with superconductors connected to a ballistic normal metal billiard since each time an electron hits the superconducting part it is retroreflected as a hole (and vice versa). Using a semiclassical framework for systems with chaotic dynamics, we show how this reflection, along with the interference due to subtle correlations between the classical paths of electrons and holes inside the system, is ultimately responsible for the gap formation. The treatment can be extended to include the effects of a symmetry-breaking magnetic field in the normal part of the billiard or an Andreev billiard connected to two phase-shifted superconductors. Therefore, we are able to see how these effects can remold and eventually suppress the gap. Furthermore, the semiclassical framework is able to cover the effect of a finite Ehrenfest time, which also causes the gap to shrink. However, for intermediate values this leads to the appearance of a second hard gap-a clear signature of the Ehrenfest time. [less ▲]
