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 ▲]

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.

Aim of the study : To evaluate the role of perioperative, catheter-guided fibrinolysis in the management of thrombosed popliteal artery aneurysms. Material : From 1990 to 2005, six patients suffering subacute limb ischemia, secondary to thrombosis of a popliteal artery aneurysm, benefited selective intra-arterial fibrinolysis, followed by subsequent aneurysm exclusion and bypass grafting. This represents ten percent of all popliteal aneurysms operated on in that time period and 28% of all thrombosed popliteal artery aneurysms. Results : The lytic procedure was successful in all cases, restituting patency in two (n = 3), one (n = 2) or all (n = 1) crural arteries. The venous bypass graft remained patent in all but one patient. In one patient, the graft occluded at 10 months without limb loss. This outcome compares more favorable than the result obtained with emergent surgery alone for thrombosed popliteal artery aneurysms with profound limb ischemia (eight patients, of whom one required amputation at day 5 and one lost his limb at nine months following graft thrombosis). Conclusion : Preoperative intra-arterial lytic therapy, in the setting of subacute limb ischemia caused by thrombosis of a popliteal artery aneurysm, can be considered as safe and effective.

An exceptionally large specimen of the early land plant Cooksonia paranensis Gerrienne et al. has been discovered from the type locality (Jackson de Figueiredo, Parana Basin, Brazil; early Lochkovian, Early Devonian). This nearly complete specimen consists of five dichotomous axes attached at their base to a small thalloid(?) structure. Each terminal axis segment ends in an expanded, cup-like, empty tip. Three interpretations of the specimen are proposed. (1) The whole specimen is a gametophyte of the Sciadopkyton-type, with a central area from which five axes depart; under this interpretation, the terminal cups are gametangiophores. (2) The basal structure represents the remains of a rhizome bearing five upright aerial axes, in which case the whole plant is a sporophyte. (3; our favoured hypothesis) The specimen is a cluster of five individual sporophytes still attached to the remains of a small female or bisexual gametophyte. In the latter case, this fossil is evidence that reduced thalloid gametophytes and branched axial sporophytes are plesiomorphic among the earliest eutracheophytes. We suggest that a major difference in life cycle defines a basal dichotomy in tracheophytes. Eutracheophyta, including all living vascular plants, have a heteromorphic, sporophyte dominant alternation of generations, whereas their extinct sister-group Rhymopsida (renamed here Paratracheophyta) is characterised by a more or less isomorphic alternations of generations.

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 ▲]

We propose a multi-dimensional strategy, associating immunodetection to a protein fractionating two-dimensional liquid chromatography tool, for serological characterization of microbial antigens. The originality of such immunoproteomic approaches resides in their application in large-scale studies for rapid serotyping of micro-organisms, evaluation of immunomes and could be proposed in the development and monitoring of vaccines.

Condrusia rumex Stockmans 1948 occurs in several localities of the Belgian Evieux Formation (late Famennian, Upper Devonian). It consists of a hastate organ borne at the tip of "slender, dichotomizing" axes. Various interpretations have been given to this intriguing structure, ranging from a spore-bearing organ to a fern prothallus but recent investigations consider Condrusia to be an ovulate structures produced by early seed plants. The genus Condrusia includes 3 species: C rumex Stockmans, C. minor Stockmans and C. brevis Petrosjan. C rumex was described by Stockmans in 1948, who provided a diagnosis and illustrations, but failed to designate a holotype. We are currently reinvestigating the genus and we here designate and illustrate a lectotype for the genus and species C. rumex. (c) 2006 Elsevier B.V. All rights reserved. [less ▲]

Where distributed agents must share voluminous set mem- bership information, Bloom filters provide a compact, though lossy, way for them to do so. Numerous recent networking papers have examined the trade-offs between the bandwidth consumed by the transmission of Bloom filters, and the er- ror rate, which takes the form of false positives, and which rises the more the filters are compressed. In this paper, we introduce the retouched Bloom filter (RBF), an extension that makes the Bloom filter more flexible by permitting the removal of selected false positives at the expense of gen- erating random false negatives. We analytically show that RBFs created through a random process maintain an overall error rate, expressed as a combination of the false positive rate and the false negative rate, that is equal to the false positive rate of the corresponding Bloom filters. We further provide some simple heuristics that decrease the false posi- tive rate more than than the corresponding increase in the false negative rate, when creating RBFs. Finally, we demon- strate the advantages of an RBF over a Bloom filter in a dis- tributed network topology measurement application, where information about large stop sets must be shared among route tracing monitors.

The polled locus has been mapped by genetic linkage analysis to the proximal region of bovine chromosome 1. As an intermediate step in our efforts to identify the polled locus and the underlying causative mutation for the polled phenotype, we have constructed a BAC-based physical map of the interval containing the polled locus. Clones containing genes and markers in the critical interval were isolated from the TAMBT (constructed from Angus and Longhorn genomic DNA) and CHORI-240 (constructed from horned Hereford genomic DNA) BAC libraries and ordered based on fingerprinting and the presence or absence of 80 STS markers. A single contig spanning 2.5 Mb was assembled. Comparison of the physical order of STSs to the corresponding region of human chromosome 21 revealed the same order of genes within the polled critical interval. This contig of overlapping BAC clones from horned and polled breeds is a useful resource for SNP discovery and characterization of positional candidate genes. [less ▲]

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 ▲]
