La vérification de programmes consiste à analyser les comportements possibles de programmes en vue de déterminer s’ils seront toujours conformes à ce qui est attendu. Pour ce faire, les caractéristiques souhaitées des comportements sont exprimées formellement et confrontées, par des techniques mathématiques rigoureuses, à l’ensemble des comportements du programme à analyser. Dans ce contexte, les automates jouent un triple rôle. Tout d’abord, ils sont fréquemment utilisés en tant que langage de programmation simplifié pour décrire les programmes à analyser. Ensuite, ils servent de formalisme de description de propriétés de comportements, soit directement, soit par traduction à partir d’un langage logique. Finalement, ils s’avèrent très utiles en tant que formalisme de description d’ensembles infinis de valeurs. [less ▲]

The smallness of the observed neutrino masses might have a radiative origin. Here we revisit a specific two-loop model of neutrino mass, independently proposed by Babu and Zee. We point out that current constraints from neutrino data can be used to derive strict lower limits on the branching ratio of flavour changing charged lepton decays, such as μ→eγ. Non-observation of Br(μ→eγ) at the level of 10^(−13) would rule out singly charged scalar masses smaller than 590 GeV (5.04 TeV) in case of normal (inverse) neutrino mass hierarchy. Conversely, decay branching ratios of the non-standard scalars of the model can be fixed by the measured neutrino angles (and mass scale). Thus, if the scalars of the model are light enough to be produced at the LHC or ILC, measuring their decay properties would serve as a direct test of the model as the origin of neutrino masses.

Analyses of the natural abundance of carbon and nitrogen stable isotopes were performed to investigate the feeding habits of two ophiurolds, Ophiomastix venosa and Ophiocoma scolopendrina, and to assess the potential benefit obtained by the symbiotic Ophiomastix venosa juveniles. A tracer experiment was also carried Out to clarify the contribution of algae to the nitrogen uptake amongst the tested ophiurolds. Our results suggest that Ophiocoma scolopendrina adults occupy a higher position in the food web than Ophiomastix venosa and mainly feed on neuston. In contrast, O. venosa adults feed on the alga Sargassum densifolium, and on organic matter associated with sediment. Free juveniles and symbiotic juveniles of O. venosa have intermediate PC values between both adult species. The high proportion of C-13 in the symbiotic juveniles compared to the one in their conspecific adults indicates that their diet slightly differs from the latter and is closer to that of Ophiocoma scolopendrina. This raises the hypothesis that symbiotic juveniles steal neuston front their associated host, O. scolopendrina. [less ▲]

The aim of concrete surface preparation prior to repair is to obtain a surface with properties close to that of the bulk concrete. In this paper, the results of an investigation intended to evaluate the mechanical degradation induced by different surface preparation techniques are presented. Optical microscope observations clearly show that more cracking is induced with jack-hammers than with the other investigated techniques and that the cracking density increases with the hammer weight. While more information is needed to evaluate quantitatively the effects of concrete removal operations, it appears from the reported results that techniques such as sandblasting, scarifying and water jetting are preferable, as they clearly leave much less defects in the substrate.

Topology discovery systems are starting to be in- troduced in the form of easily and widely deployed software. Unfortunately, the research community has not examined the problem of how to perform such measurements efficiently and in a network-friendly manner. This paper describes several contributions towards that end. These were first presented in the proceedings of ACM SIGMETRICS 2005. We show that standard topology discovery methods (e.g., skitter) are quite inefficient, repeatedly probing the same interfaces. This is a concern, because when scaled up, such methods will generate so much traffic that they will begin to resemble DDoS attacks. We propose two metrics focusing on redundancy in probing and show that both are important. We also propose and evaluate Doubletree, an algorithm that strongly reduces redundancy while maintaining nearly the same level of node and link coverage. The key ideas are to exploit the tree-like structure of routes to and from a single point in order to guide when to stop probing, and to probe each path by starting near its midpoint. Following the SIGMETRICS work, we implemented Doubletree, and deployed it in a real network environment. This paper describes that implementation, as well as preliminary favorable results. [less ▲]

Nowadays, the management of ectopic pregnancy should be codified as often as possible. Two types of treatment are possible. One surgical and the other medical. Our study is concerned with a series of 97 patients hospitalized for suspicion of ectopic pregnancy for whom the risk factors and treatment were analyzed. Our conclusion is that the medical treatment should be more frequently proposed and surgery should prefer the conservative treatment whenever it is still possible. [less ▲]

BACKGROUND: This study evaluates the accuracy of [F]fluorodeoxyglucose positron emission tomography (F-FDG PET) imaging with semi-quantitative analysis for differentiating benign from malignant pleural exudates and for guiding the search for the primary tumour of pleural metastases. METHODS: Whole-body 18F-FDG PET was performed in 79 patients with exudative pleurisy. Standard uptake values were normalized for body weight, body surface area, lean body mass (SUVbw, SUVbsa, SUVlbm) with and without correction for blood glucose levels. Thoracoscopy was systematically performed to reveal pathological diagnosis. RESULTS: All SUVs were significantly higher in all malignant pleural diseases (n = 51) than in benign (n = 28) (P < 0.001). Moreover SUVs were greater in the pleural metastases from pulmonary primaries (n = 25) and in mesotheliomas (n = 8) than in extrathoracic primaries (n = 18) (P < 0.01) with no significant difference between lung cancers and mesotheliomas. Receiver operating curve (ROC) analysis between benign and malignant lesions showed areas under the curves that ranged from 0.803 (SUVbsa g) to 0.863 (SUVbw). The cut-off value for SUVbw which gave the best accuracy (82.3%) was 2.2. When comparing thoracic with extrathoracic primaries the highest accuracy (80.4%) was found for a cut-off value of 2.6. CONCLUSION: Semi-quantitative analysis of 18F-FDG PET imaging helps to differentiate malignant from benign pleural exudates and to distinguish between thoracic or extrathoracic primaries. [less ▲]

A study is presented on the crystallization of ornithine acetyltransferase from yeast, which catalyzes the fifth step in microbial arginine synthesis. The use of the counter-diffusion technique removes the disorder present in one dimension in crystals grown by either the batch or hanging-drop techniques. This makes the difference between useless crystals and crystals that allow successful determination of the structure of the protein. The crystals belong to space group P4, with unit-cell parameters a = b = 66.98, c = 427.09 angstrom, and a data set was collected to 2.76 angstrom. [less ▲]

Les changements causés par le vieillissement se déroulent à un rythme différent pour chaque personne et dépendent de facteurs comme le style de vie, les activités et l'environnement ainsi que des facteurs comme le bagage génétique et l'état de santé.La presbyphonie est le terme employé pour définir le vieillissement de la voix. Elle s'observe le plus souvent après 60 ans et touche les deux sexes. Ce trouble vocal est la conséquence d'altérations morphologiques et fonctionnelles des systèmes pneumo-phono-articulatoires qui résultent d'une modification hormonale (thyroïdienne et sexuelles), d'une altération de l'état musculaire, vasculaire, nerveux ou respiratoire, ou encore d'un manque d'exercice vocal.

This article presents the data on cost of the major brain disorders in Belgium which were retrieved from "Cost of Disorders of the Brain in Europe" study sponsored by the European Brain Council and performed by Stockholm Health Economics. The disorders selected were : addiction, depression, anxiety disorders, brain tumours, dementia, epilepsy, migraine and other headaches, multiple sclerosis, Parkinson's disease, psychotic disorders, stroke and trauma. Figures for prevalence of disorders and direct medical, direct non-medical and indirect costs are based on data coming from available electronic data bases, or when missing for Belgium, best possible estimates or extrapolated data were used. All economic data were transformed to E's for 2004 and adjusted for purchasing power parity (PPP). The results show that the total number of people with any brain disorder in Belgium amounts to 2,9 million in 2004, the most prevalent being anxiety disorders 1.1 million, migraine 860 000, addiction (any) 800.000 and depression 500.000 cases. The total cost of all included brain disorders in Belgium was estimated at 10.6 billion Euros. Most costly per case are brain tumours, multiple sclerosis, stroke and dementia. Because of their higher prevalence, however, depression, dementia, addiction, anxiety disorders and migraine have the highest total costs. Taken together, brain disorders consume 4% of the gross national product and cost each citizen of Belgium E 1029 per year The drug costs for brain disorders constitute only 10% of the total drug market in Belgium, and only 4% of the total cost of brain disorders in Belgium. This should be compared to the cost estimates and to a previous study which showed that brain disorders are responsible for 35% of the total burden of all disorders in Europe. This study suggests therefore that the direct healthcare resources, including expenses for drug therapies, allocated to brain disorders in Belgium are not leveled to the indirect costs and burden of these disorders. A comparison with data available from a direct prospective study in demented Belgian patients suggests that the mathematical estimates presented here reflect quite accurately the real average cost for dementia, although there are large variations depending on disease severity. As, in addition, subjects with brain disorders face collateral costs which have not been taken into account and may vary between countries, it seems worthwhile to conduct, in cooperation with patients associations, a complementary survey in the Belgian ecosystem to establish the cost profile of representative patients for the major brain disorders. Such a survey is being organized by a task force of the Belgian Brain Council. [less ▲]
