This paper addresses the problem of making text mining results more comprehensible to humanities scholars, journalists, intelligence analysts, and other researchers, in order to support the analysis of text collections. Our system, FeatureLens<sup>1</sup>, visualizes a text collection at several levels of granularity and enables users to explore interesting(More)
Indexing and segmenting of video content by motion, color and texture has been intensively explored leading to a usual representation in a storyboard. In this paper, a novel method of visualization of video content is proposed. First of all, the content is segmented into shots, and then a spatio-temporal color signature of shots, based on color distribution(More)
The ability to find interesting patterns in sequential datasets is important in both data analysis and knowledge discovery. Shapes, such as spikes, valleys, and increasing lines, created when graphing sequential data points are familiar to analysts as a way of identifying trends and anomalous behaviors. This work presents a set of common shapes that can be(More)

Sphingosine 1-phosphate (S1P, 1) regulates vascular barrier and lymphoid development, as well as lymphocyte egress from lymphoid organs, by activating high-affinity S1P 1 receptors. We used reversible chemical probes (i) to gain mechanistic insights into S1P systems organization not accessible through genetic manipulations and (ii) to investigate their(More)
