Online social networks play a major role in the spread of information at very large scale. A lot of effort have been made in order to understand this phenomenon, ranging from popular topic detection to information diffusion modeling, including influential spreaders identification. In this article, we present a survey of representative methods dealing with(More)
The ever-growing number of people using Twitter makes it a valuable source of timely information. However, detecting events in Twitter is a difficult task, because tweets that report interesting events are overwhelmed by a large volume of tweets on unrelated topics. Existing methods focus on the textual content of tweets and ignore the social aspect of(More)
The hippocampus is critical for learning and memory, and injury to this structure is associated with cognitive deficits. The response of the hippocampal microvessels after a relatively low dose of high-LET radiation remains unclear. In this study, endothelial population changes in hippocampal microvessels exposed to (56)Fe ions at doses of 0, 0.5, 2 and 4(More)
Profiling gene expression in endothelial cells provides a strategy for developing a molecular understanding of normal vascular physiology and disease processes involving angiogenesis and vascular remodeling. However, the purification of endothelial cells for this purpose has been challenging because of the difficulty of isolating the cells and their low(More)
Profiling gene expression in endothelial cells advances the understanding of normal vascular physiology and disease processes involving angiogenesis. However, endothelial cell purification has been challenging because of the difficulty of isolating cells and their low abundance. Here we examine gene expression in endothelial cells freshly isolated from lung(More)
RÉSUMÉ. Dans le cadre d’une collaboration avec LCL-Le Crédit Lyonnais, nous avons conçu un entrepôt de données à partir des sources de données de l’établissement bancaire pour répondre aux besoins d’analyse des utilisateurs concernant les opérations marketing. Cependant, ces besoins sont amenés à évoluer rapidement. Dans cet article, nous proposons alors(More)

Integrin alpha5beta1 is among the proteins overexpressed on tumor vessels and is a potential target for diagnostics and therapeutics. Here, we mapped the distribution of alpha5beta1 integrin in three murine tumor models and identified sites of expression that are rapidly accessible to intravascular antibodies. When examined by conventional(More)
