Les polyn^ omes d'Ehrhart constituent un r esultat math ematique important, permettant d'exprimer le nombre de solutions enti eres d'un syst eme d' equations et d'in equations rationnelles et param etriques. L'informatique trouve ici un outil permettant une analyse symbolique exacte des programmes. Nous montrons dans cet article que le math ematicien Eug ene Ehrhart a pos e les bases d'un vaste...

Multivariate pattern analysis (MVPA) is a powerful tool for relating theories of cognitive function to the neural dynamics observed while people engage in cognitive tasks. Here, we use the Context Maintenance and Retrieval model of free recall (CMR; Polyn et al., 2009a) to interpret variability in the strength of task-specific patterns of distributed neural activity as participants study and re...

La catégorisation du pentecôtisme comme « charismatique » découle logiquement, d’un point de vue théologique, sa vive attention aux « dons Saint-Esprit » (charismata). D’un sociologique, en revanche, une association trop systématique avec l’idéal-type wébérien la légitimité charismatique,...

Tanaka’s approach to swelling kinetics of a solid gel sphere is extended to a sphericalmicrogel shell. The boundary condition at the inner surface is obtained from the minimization of shear elastic energy. Temporal evolution of a shell is represented in a form of expansion over eigenfunctions of the corresponding diffusion equation. The swelling of Tanaka’s solid spherical gel is recovered as a...

Prior work on organization in free recall has focused on the ways in which semantic and temporal information determine the order in which material is retrieved from memory. Tulving's theory of ecphory suggests that these organizational effects arise from the interaction of a retrieval cue with the contents of memory. Using the continual-distraction free-recall paradigm [Bjork, R. A., & Whitten,...

The N-terminal starch binding domain of Rhizopus oryzae glucoamylase (RoSBD) has a high binding affinity for raw starch. RoSBD has two ligand-binding sites, each containing a ligand-binding clamp: a polyN clamp residing near binding site I is unique in that it is expressed in only three members of carbohydrate binding module family 21 (CBM21) members, and a Y32/F58 clamp located at binding site...

The human memory system is remarkable in its capacity to focus its search on items learned in a given context. This capacity can be so precise that many leading models of human memory assume that only those items learned in the context of a recently studied list compete for recall. We sought to extend the explanatory scope of these models to include not only intralist phenomena, such as primacy...

{ We show that there exists a toric curve in P 8 , whose homogeneous coordinate ring has a presentation with 12 quadratic relations and whose Poincar e-Betti series is irrational. The example was found by a computer search, aiming at a homological classiication of those toric curves that have a quadratic presentation in P n?1 for n 9. Some other consequences of this search are also presented. U...
