The Liège intranuclear cascade (INCL) model is shortly presented. The predictive power of its standard version concerning the description of nucleon-induced spallation reactions in the 200 MeV to ~2 GeV range of incident energy is indicated. Current improvements of the model, in particular its extension to higher energies, are emphasized. The capabilities of the model for possible applications in astrophysics, space research and protontherapy are pointed out. [less ▲]

Erlotinib is an inhibitor of the tyrosine-kinase domain of the epidermal growth factor receptor-1 (EGFR). This drug is used to treat some solid cancers, particularly advanced non-small-cell lung carcinoma. Similar to other EGFR inhibitors, erlotinib is responsible for a series of skin adverse reactions, particularly acneiform lesions. We described the incidental effect of erlotinib on actinic keratoses which became markedly inflamed and showed partial regression. Inflammation appeared to spontaneously decrease while on erlotinib treatment. This reaction in the skin neoplasm is perhaps a visible and accessible model for predicting the effect in the deep-seated neoplasm targeted by the drug. [less ▲]

Many large-scale Internet applications optimize their overlay network to reduce latencies. Embedding coordinate systems like Vivaldi are valuable tools for this new range of applications since they propose light-weight algorithms that permit to estimate the latency between any pair of nodes without having to contact them first. It has been recently demonstrated that coordinate systems in general and Vivaldi in particular are sensible to attacks. Typically, nodes can lie about their coordinate and distort the coordinate space. In this paper, we propose a formal reputation model to detect misbehaving nodes and propose a reputation adaptation of Vivaldi called RVivaldi. We evaluate the performance of RVivaldi using the King dataset and show that RVivaldi is less sensitive to malicious nodes than Vivaldi. [less ▲]

Glycosaminoglycans (GAGs) commonly participate in herpesvirus entry. They are thought to provide a reversible attachment to cells that promotes subsequent receptor binding. Murine gamma-herpesvirus-68 (MHV-68) infection of fibroblasts and epithelial cells is highly GAG-dependent. This is a function of the viral gp150, in that gp150-deficient mutants are much less GAG-dependent than wild-type. Here we show that the major MHV-68 GAG-binding protein is not gp150 but gp70, a product of ORF4. Surprisingly, ORF4-deficient MHV-68 showed normal cell binding and was more sensitive than wild-type to inhibition by soluble heparin rather than less. Thus, the most obvious viral GAG interaction made little direct contribution to infection. Indeed, a large fraction of the virion gp70 had its GAG-binding domain removed by post-translational cleavage. ORF4 may therefore act mainly to absorb soluble GAGs and prevent them from engaging gp150 prematurely. In contrast to gp70, gp150 bound poorly to GAGs, implying that it provides little in the way of adhesion. We hypothesize that it acts instead as a GAG-sensitive switch that selectively activates MHV-68 entry at cell surfaces. [less ▲]

Colorectal cancer is the second leading cause of death in Northern countries and needs a national screening program to reduce mortality and improve quality of life. Screening has to be cost-effective and acceptable for patients. Many screening tools, invasive or not, are existing and often debated: FOBT, sigmoidoscopy and complete colonoscopy. New tools are in development and have to be evaluated in current practice: virtual colonoscopy, new endoscopic technologies, DNA on faeces or proteomics with markers in serum. [less ▲]

Le risque de pénurie en eau au Maroc s’accroît sous la pression conjuguée de la sécheresse et de la demande domestique et industrielle. Il doit être pris en compte dans toute gestion de l’eau aussi bien au niveau de l’agriculture pluviale qu’irriguée. Les stratégies pour réduire le risque de sécheresse agricole, peuvent être classées en trois catégories : i) en agriculture irriguée, économiser l’eau en réduisant les pertes et en améliorant l’efficience d’utilisation de l’eau \; ii) en zones forestières et pastorales, bénéficier de l’eau perdue actuellement par le processus d’évaporation en développant les écosystèmes pastoraux et fruitiers \; iii) en agriculture pluviale, augmenter la productivité par les techniques de conservation de l’eau qui consistent à améliorer la collecte, le stockage et l’utilisation de l’eau au niveau de l’exploitation. Des mesures publiques additionnelles sont nécessaires, principalement les systèmes d’alerte précoce incluant la prévision saisonnière du climat et la prévision agro-météorologique, pour promouvoir l’investissement dans les environnements secs et mettre à la disposition des agriculteurs et des pouvoirs publics des outils d’aide à la décision. L’adoption d’une gestion efficiente de l’eau de pluie et d’irrigation permettra d’assurer la sécurité alimentaire et de libérer l’eau pour les besoins non agricoles. [less ▲]

One unresolved conceptual problem in some Palaeozoic sedimentary strata is the boundary between the concepts of ‘shell concentration’ and ‘reef’. In fact, numerous bioclastic strata are transitional coquina–reef deposits, because either distinct frame-building skeletons are not commonly preserved in growth position, or skeletal remains are episodically encrusted by ‘stabilizer’ (reef-like) organisms, such as calcareous and problematic algae, encrusting microbes, bryozoans, foraminifers and sponges. The term ‘parabiostrome’, coined by Kershaw, can be used to describe some stratiform bioclastic deposits formed through the growth and destruction, by fair-weather wave and storm wave action, of meadows and carpets bearing frame-building (archaeocyaths, bryozoans, corals, stromatoporoids, etc.) and/or epibenthic, non-frame-building (e.g. pelmatozoan echinoderms, spiculate sponges and many brachiopods) organisms. This paper documents six Palaeozoic examples of stabilized coquinas leading to (pseudo)reef frameworks. Some of them formed by storm processes (generating reef soles, aborted reefs or being part of mounds) on ramps and shelves and were consolidated by either encrusting organisms or early diagenesic processes, whereas others, bioclastic-dominated shoals in barrier shelves, were episodically stabilized by encrusting organisms, indicating distinct episodes in which shoals ceased their lateral migration [less ▲]

Clownfishes live in social group within sea anemones. They are prolific “singers” that produce a wide variety of sounds, described as “pops” and “chirps”, involved in both reproductive and agonistic interactions. Although clownfish sounds were recorded since 1930, the mechanism of sound production has remained unresolved. The sounds used to describe the sonic mechanism were directed towards hetero- and conspecifics that approach their sea anemone host. Sound recordings were synchronized using a high speed video (500 fps) coupled or not with an X-ray system. These systems allowed to quantify the movements of external and internal bones during sound production. Sounds were typically accompanied by rapid (< 30 ms) head movements such as elevation of the skull, lowering of the hyoid bar and the anterior part of the branchial basket, retraction of the pectoral girdle, and finally closing of the mouth. Synchronization of sound pulses with X-ray images indicates that sound is produced when the hyoid apparatus is completely lowered and the mouth closed by a previously unknown mechanism. Dissections of freshly dead specimens reveal an unusual ligament responsible for the rapid mouth closing. This ligament joins the hyoid bar to the internal part of the mandible. Acting as a cord, it forces the mandible to turn around its articulation during the lowering of the anterior part of the branchial basket, forcing the mouth to close. Sounds result from the collision of the jaw teeth, transferring energy to the jaws that are presumably the sound radiator. [less ▲]

This paper presents the experimental and numerical tests made on the Titanium based alloy Ti6A14V to identify its yield locus and the hardening behaviour. A bi-axial experimental equipment has been used to perform cyclic shear tests, simple shear tests and successive simple shear tests and plane-strain tests. Coupled with classical tensile tests, these tests enable to identify the yield locus and the hardening model. Teodosiu and Hu’s hardening law and isotropic Swift type hardening and kinematic Armstrong Frederick hardening models have been investigated. [less ▲]

Many computational intensive bioinformatics software, such as multiple sequence alignment, population structure analysis, etc., written in C/C++ are not multicore-aware. A multicore processor is an emerging CPU technology that combines two or more independent processors into a single package. The Single Instruction Multiple Data-stream (SIMD) paradigm is heavily utilized in this class of processors. Nevertheless, most popular compilers including Microsoft Visual C/C++ 6.0, x86 gnu C-compiler gcc do not automatically create SIMD code which can fully utilize the advancement of these processors. To harness the power of the new multicore architecture certain compiler techniques must be considered. This paper presents a generic compiling strategy to assist the compiler in improving the performance of bioinformatics applications written in C/C++. The proposed framework contains 2 main steps: multithreading and vectorizing strategies. After following the strategies, the application can achieve higher speedup by taking the advantage of multicore architecture technology. Due to the extremely fast interconnection networking among multiple cores, it is suggested that the proposed optimization could be more appropriate than making use of parallelization on a small cluster computer which has larger network latency and lower bandwidth.
