Cognitive biases for alcohol-related stimuli have been shown to play a major role in the maintenance of alcohol addiction, thus making their study an issue of paramount importance. Such cognitive biases have been traditionally investigated with low-level, non-inferential processes, such as the Stroop task [for a review see Psychol. Bull. 120 (1996) 3]. However, explanations for these effects [f...

We present in this paper optimal and accelerated row projection algorithms arising from the use of quadratic programming, that allow us to define the iterate xk+1 as the projection of x onto a hyperplane which minimizes its distance to the solution x∗. These algorithms also use a novel partition strategy into blocks based on sequential estimations of their condition numbers.  2001 IMACS. Publi...

To test the hypothesis that selective breeding for high voluntary wheel running negatively affects maternal performance in house mice, we observed maternal behavior and compared litter size and mass, in replicate lines of selected (N=4) and control (N=4) mice from generations 20 and 21 of an artificial selection experiment. At generation 21, selected-line females ran 2.8-times more revolutions ...

Parallel implementation of the Bi-CGSTAB method with block red-black Gauss-Seidel preconditioner applied to the Hermite collocation discretization of partial differential equations

We describe herein the parallel implementation of the Bi-CGSTAB method with a block Red-Black Gauss-Seidel (RBGS) preconditioner applied to the systems of linear algebraic equations that arise from the Hermite collocation discretization of partial di erential equations in two spatial dimensions. The method is implemented on the Cray T3E, a parallel processing supercomputer. Speedup results are ...
