Let G = (V; A) be an antisymmetric directed graph. An oriented-coloring of G is deened as a mapping c from V to the set of colors f1;2;:::;g satisfying (i) 8 (x; y) 2 A; c(x) 6 = c(y) and (ii) 8 (x; y); (z; t) 2 A; c(x) = c(t) =) c(y) 6 = c(z). The oriented chromatic polynomial of G is then deened as the quantity ~ P (G;), standing for the number of oriented-colorings of G. We show in this pape...

In neurohistochemistry the lectins are considered profitable biomarkers of glycoconjugates found in the extracellular space or at the cell surface. Glycoconjugates (glycoproteins and glycolipids) can be considered mediators of differentiation and growth during the maturation of the central nervous system (De Grauw & Liwricz, 1986). The lectins recognize specific residues of sugars or their nitr...

Repeating an item in a list benefits recall performance, and this benefit increases when the repetitions are spaced apart (Madigan, 1969; Melton, 1970). Retrieved context theory incorporates 2 mechanisms that account for these effects: contextual variability and study-phase retrieval. Specifically, if an item presented at position i is repeated at position j, this leads to retrieval of its cont...

A uniied treatment of parameters relevant to factoring polynomials over nite elds is given. The framework is based on generating functions for describing parameters of interest and on singularity analysis for extracting asymptotic values. An outcome is a complete analysis of the standard polynomial factorization chain that is based on elimination of repeated factors, distinct degree factorizati...

A stabilized mixed hp Finite Element Method (FEM) of Galerkin Least Squares type for the Stokes problem in polygonal domains is presented and analyzed. It is proved that for equal order velocity and pressure spaces this method leads to exponential rates of convergence provided that the data is piecewise analytic. R esum e: Nous etudions la version hp d'une m ethode d' el ements nis mixte, stabi...

In this paper, we present an upwinding methodology for systems of conservation laws. Our aim is to construct upwind schemes which do not require the extraction of the eigensystem of the jacobian matrix (but just the knowledge of the eigenvalues) and rely on the introduction of an appropriate polynomial approximation. @U @t + @F(U) @x = 0; t > 0; x 2 I R ; (1) avec U(x; t) un etat de l'espace de...

| In a note at the end of his paper Recherches sur les fractions continues, Stieltjes gave a necessary and suucient condition when a continued fraction is represented by a meromorphic function. This result is related to the study of compact Jacobi matrices. We indicate how this notion was developped and used since Stieltjes, with special attention to the results by M. G. Krein. We also pay atte...

GA (glucoamylase) hydrolyses starch and polysaccharides to beta-D-glucose. RoGA (Rhizopus oryzae GA) consists of two functional domains, an N-terminal SBD (starch-binding domain) and a C-terminal catalytic domain, which are connected by an O-glycosylated linker. In the present study, the crystal structures of the SBD from RoGA (RoGACBM21) and the complexes with beta-cyclodextrin (SBD-betaCD) an...
