L’objectif de ce papier est de comparer la 2-catégorie des théories homotopiques de Quillen combinatoires propres à gauche avec une 2-catégorie de dérivateurs de Grothendieck. La 2-catégorie THQcpg des théories homotopiques de Quillen combinatoires propres à gauche est la bi-localisation de la 2-catégorieModQcpg des catégories modèles de Quillen combinatoires propres à gauche relativement aux é...

This report explores some numerical alternatives that can be exploited to derive efficient low-order models of the Navier-Stokes equations. It is shown that an optimal solution sampling can be derived using appropriate norms of the Navier-Stokes residuals. Then the classical Galerkin approach is derived in the context of a residual minimization method that is similar to variational multiscale m...

Amyotrophic lateral sclerosis (ALS) and Parkinson's disease, both progressive neurodegenerative diseases, affect >1 million Americans (1,2). Consistently reported risk factors for ALS include increasing age, male sex, and cigarette smoking (1); risk factors for Parkinson's disease include increasing age, male sex, and pesticide exposure, whereas cigarette smoking and caffeine consumption are in...

In this paper we are presenting a new database with handwritten Arabic town/village names. For each name the ground truth information, e.g. the sequence of character shapes, some style information, and the baseline are coded. 411 writers filled forms with about 26400 names containing more than 210000 characters. The database is described in detail. It is designed for training and testing recogn...

The effect of zinc on the biological reduction of hematite (alpha-Fe2O3) by the dissimilatory metal-reducing bacterium (DMRB) Shewanella putrefaciens CN32 was studied in the presence of four natural organic materials (NOMs). Experiments were performed under non-growth conditions with H2 as the electron donor and zinc inhibition was quantified as the decrease in the 5 d extent of hematite biored...
