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...

Background: Municipal waste incineration are one of the largest resources of 2,3,7,8- tetrachlorodibenzo-pdioxins (TCDDs) and Polychlorinated dibenzofurans (PCDFs) from incineration ends up in water and food cycle are taken up by fish and etc. These gaseous emission products tend to give rise to concern due to their carcinogenic potential, as well as their potential adverse health effects on re...

This study explores the claim that headache management can be improved by evaluating current emergent care. A retrospective chart review investigated primary complaints of headache during a three-month period. Two hundred and twenty seven patients were identified for review and three-month follow-up using fully available records and imaging. A total of 543/8,759 had a neurological condition. Th...

The purpose of this study is to describe and evaluate the success rate of combined glaucoma and small cataract surgery by means of a one-site versus two-site approach. Fifty-eight eyes of fifty-five patients undergoing combined surgery were operated: thirty-one eyes underwent two-site approach and twenty-seven eyes underwent one-site approach. Short term and long term mean intraocular pressure ...

We propose and test a BI Success model, based on DeLone and McLean’s IS Success model, that incorporates comprehensive data that is needed for decision-making and computer systems that allow integration and analysis of that data as dimensions of BI success. Our model also includes organizational support structure for BI and the users’ involvement in the ongoing development of BI systems as cont...

BACKGROUND Nonattendance for scheduled appointments disturbs the effective management of pediatric pulmonary clinics. We hypothesized that the reasons for non-attendance and the necessary solutions might be different in pediatric pulmonary medicine than in other pediatric fields. We therefore investigated the factors associated with nonattendance this field in order to devise a corrective strat...
