This paper describes XRCE’s participation in Large Scale Visual Concept Detection and Annotation Task [16] and Photo Retrieval Task [17] of ImageCLEF 2009. Those tasks both use a new collection which is different and which is much larger than the ones used in past sessions. Moreover, new kinds of challenge to tackle were designed such as new categories to detect or new types of topic to deal wi...

The authors show by illustration that procedures used to validate the reliability of single-concentration high-throughput screens such as the signal window and Z' factor do not ensure sufficient reliability in potency estimates from concentration response assays. They develop the minimum significant ratio as a statistical parameter to characterize the fold change between 2 compounds run in the ...

In this work we present a probabilistic model to estimate summaries of Affymetrix GeneChip probe level data. Comparisons with two different models were made both on a publicly available dataset and on a study performed in our laboratory, showing that our model performs better for consistency of fold change.

Biochemical regulatory networks governing diverse cellular processes such as stress-response, differentiation and cell cycle often contain coupled feedback loops. We aim at understanding how features of feedback architecture, such as the number of loops, the sign of the loops and the type of their coupling, affect network dynamical performance. Specifically, we investigate how bistability range...

In this work, we study the volume ratio of the projective tensor products `p ⊗π `q ⊗π `r with 1 ≤ p ≤ q ≤ r ≤ ∞. We obtain asymptotic formulas that are sharp in almost all cases. As a consequence of our estimates, these spaces allow for a nearly Euclidean decomposition of Kašin type whenever 1 ≤ p ≤ q ≤ r ≤ 2 or 1 ≤ p ≤ 2 ≤ r ≤ ∞ and q = 2. Also, from the Bourgain-Milman bound on the volume rat...

A soft tissue drape that is formed around the tooth, as it emerges from bone, has both aesthetic and functional significance. Post-extraction hard changes are inevitable leads to a buccal concavity. The pontics for tooth or implant supported fixed partial denture in such cases appear longer. Preservation of part root preserves periodontal apparatus hence facilitates optimal region pontic site d...

When designing clothes, fashion designers consider drape and movement of clothes as important factors. To reduce the burden on pattern makers to save costs operation time in apparel product design process, development more realistic dressing simulation system reflecting mechanical properties was required. In this paper, simple measurement methods cloth that can be introduced on-site is proposed...
