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.

En Mai 2007, un recensement hydro-agricole du bassin du Kou a été organisé par le projet et l’AEDE, et effectué par les agents de la Direction Provinciale de l’Agriculture, de l’Hydraulique et des Ressources Halieutiques. Les compétences en appui-conseil sur le terrain de la DPAHRH-Houet ainsi que la confiance dont profitent ses encadreurs dans le milieu agricole étaient indispensables pour le bon déroulement des enquêtes. L’AEDE et le projet ont assumé les besoins en formation et en matériel au niveau de la DPAHRH. Le traitement des enquêtes a été fait par le projet, les résultats et la base de données résultante ont été restitués au niveau de l’administration. Pour les différentes zones agricoles du bassin du Kou, les données suivantes ont été recensées par exploitant : données d’identification & coordonnées (GPS) ; données de cultures : superficie, calendrier, ... ; points d’exhaure : prise en rivière, puisard, ... ; caractéristiques du moyen d’exhaure ; calendrier d’irrigation ; caractéristiques du puisard & coordonnées GPS. Plus de 1.200 exploitants et groupements ont été identifiés dans les 11 différentes zones agricoles. Une base de données a été élaborée à partir de ces enquêtes. Les cartes suivantes ont été établies : occupations agricoles du bassin du Kou ; utilisation des eaux de surface vs. eaux souterraines ; moyens d’exhaure ; efficiences en irrigation ; positionnement par rapport aux berges. Les superficies potentielles irrigables sont déjà atteintes dans certaines régions, mais l’expansion est loin d’être freinée. Le grand enjeu pour le développement de l’irrigation se situe dans la gestion de la ressource en eau. La sensibilisation des agriculteurs sur les bonnes pratiques de l’irrigation permettrait de limiter les pertes lors de l’application de l’eau sur les parcelles et de réduire les inégalités d’accès à la ressource qui existent entre les utilisateurs situés en amont et en aval du cours d’eau.

A laser probing investigation has yielded the lifetimes of the 3s23p41D3d 2G7=2;9=2 metastable doublet states of Ar. The results, obtained with the CRYRING ion storage ring of Stockholm, are 3:0 0:4 and 2:1 0:1 s, respectively. Comparisons with theoretical values calculated with two independenttheoretical approaches, i.e., the pseudorelativistic Hartree-Fock method and the multiconfiguration Breit-Pauli approach, have allowed us to establish the unexpected and extraordinary strong contribution of an electric octupole (E3) transition to the ground state, in addition to the M1 decay channels to the 3d 2;4F states and the E2 contributions to the 4s 2P, 2D states.

A method for solving eddy current problems in two separate steps is developed for global-local analyses with h-conform finite element formulations. An unperturbed problem is first solved in a global mesh excluding additional conductive regions. Its solution gives the sources for a sequence of other problems, perturbed by adding conductive regions. Each problem only requires a new adapted mesh of a local region. The way the local problems and their sources are defined leads to a significant speedup of parameterized analyses, e.g., in optimization and sensitivity analyses. [less ▲]

BACKGROUND: It is a common observation that superficial freezing of normal skin and skin tumors may create a transient superficial whitening effect. In this respect, cryoscopy refers to the direct observation by dermoscopy, with or without digital recording, of the visual alterations of the frozen tissues. AIMS: To define the optimal method of cryoscopy and to describe the cryoscopy patterns of normal skin and selected skin lesions. MATERIALS AND METHODS: The influence of (a) different cryogenic sources [solid carbon dioxide (-78.5 degrees C), liquid nitrogen (N(2), -196 degrees C), and a mixture of dimethyl ether and propane (-57 degrees C)], (b) various application methods (spraying, cotton chill tips, copper plate), and (c) freezing time was assessed with regard to clinical feasability, visualization quality, and persistance time of the whitening effect. Cryoscopy patterns of normal skin, callosities and of histologically proven seborrheic keratoses, verrucous hamartomas, molluscum contagiosum, keratoacanthomas, viral warts, condylomas, actinic keratoses, dermatofibromas, skin tags, basal cell carcinomas, angiomas, and melanocytic naevi were assessed. RESULTS: The cryoscopy images of skin highlighted the skin lines. They appeared similar regardless of the freezing source and the application method. The aspects differed according to the nature of the lesions. The cotton chill tip method provided a longer whitening period compared with the other cold sources, both in normal and lesional skin. Hence, it represented the most convenient way for performing digital recording cryoscopy. On normal skin, cryoapplication was limited to about 1.5 s due to pain, resulting in whitening times ranging from 6 to 9 s, which was too short for easy digital recording. On all studied skin tumors, a 10-s N(2) freezing time was not experienced as painful, and blanching time persisted for 20-34 s, allowing easy digital recording. The whitening time was longer with increasing freezing time on both normal and lesional skin. Every single examined normal skin site and all the skin lesions showed a strong whitening effect, except heavily cornified structures, including some keratoses, callosities, and viral warts. Increased contrast of the skin surface texture was observed in almost every studied lesion. CONCLUSION: The N(2) cotton chill tip technique appeared to be the most convenient technique for cryoscopy and provided longer whitening periods compared with the other freezing sources. Pain prevented its use on normal skin, but a series of exophytic skin lesions was conveniently accessible to cryoscopy. The differences in whitening periods of various epidermal components resulted in increased visual contrast, creating typical cryoscopy images for the different exophytic skin tumors. Cryoscopy represents a novel in vivo skin imaging technique that is rapid, non-invasive, cost-effective, and easily performed. It shows both investigative and diagnostic potentials. It is remarkable that cryoscopy pictures closely resemble those yielded by skin capacitance imaging. [less ▲]

The present study focuses on the impact of microbial activities on the performance of various long-term operated laboratory-scale permeable reactive barriers. The barriers contained both aquifer and Fe-0 compartments and had received either sulfate or iron(Ill)-EDTAto promote sulfatereducing and iron(Ill)-reducing bacteria, respectively. After dismantlement of the compartments after almost 3 years of operation, DNA-based PCR-DGGE analysis revealed the presence of methanogenic, sulfate-reducing, metalreducing, and denitrifying bacteria within as well as up- and downgradient of the Fe-0 matrix. Under all imposed conditions, the main secondary phases were vivianite, siderite, ferrous hydroxy carbonate, and carbonate green rust as found by scanning electron microscopy (SEM) combined with energy dispersive X-ray analysis (EDX), and X-ray diffraction (XRD). Under sulfate-reduction promoting conditions, iron sulfides were formed in addition, resulting in 7 and 10 times higher degradation rates for PCE and TICE, respectively, compared to unreacted iron. These results indicate that the presence of sulfate-reducing bacteria in or around iron barriers and the subsequent formation of iron sulfides might increase the barrier reactivity. [less ▲]

An 11-year-old, entire male coton de tulear was presented on emergency with acute and severe depression, acute abdominal pain and vomiting of 24 hours duration. Historical complaints included right perineal swelling, dyschezia and tenesmus of 18 months duration. Abdominal ultrasonography and radiography suggested a pneumoperitoneum and positive-contrast colonography showed leakage of contrast medium into the caudal abdomen and the presence of a large retroperitoneal pouch. Exploratory laparotomy allowed the visualisation of faecal leakage from the retroperitoneal space into the peritoneal cavity. Using a perineal approach, a large necrotised rectal diverticulum filled with faeces was found over the retroperitoneal structures. A standard herniorrhaphy was then performed. The dog recovered uneventfully and dyschezia did not recur at the nine month follow-up. Rectal diverticulum rupture associated with peritonitis has not been described in the veterinary literature, to the authors' knowledge, and should be considered as a rare differential diagnosis in dogs being presented with gaseous peritonitis.

Over the last decades, significant advances were make in basic research as concerns the malignant transformation of normal cells. As a result, new targets for treatment were identified. "Targeted therapies" indicates that treatments are directed against specific molecular targets that play a major role in the activation of cell division and in the growth and dissemination of tumors. In particular, targeted therapies were developed against epithelial growth factor receptors and angiogenesis. We can expect specifise therapies against many other targets in the near future. Several drugs have obtained a marketing license. Predictive factors for tumor response and long term outcome should be developed for a better selection of the patient population who will benefit from these treatments. New imaging techniques are under development in order to assess the molecular response to these new approaches. [less ▲]
