We propose an important extension of a previously studied, spatially explicit and hydrology-driven, model of cholera spreading. Our reformulation concerns the role of different modelizations of human movement on the overall dynamics of the epidemics, which ...
Recent work by Koblitz and Menezes has highlighted the existence, in some cases, of apparent separations between the hardness of breaking discrete logarithms in a particular group, and the hardness of solving in that group problems to which the security of ...
If L/K is a finite Galois extension of local fields, then we say that the valuation criterion VC(L/K) holds if there is an integer d such that every element x is an element of L with valuation d generates a normal basis for L/K. Answering a question of Byo ...
Drug delivery is one of the most common clinical routines in hospitals, and is critical to patients’ health and recovery. It includes a decision making process in which a medical doctor decides the amount (dose) and frequency (dose interval) on the basis o ...
Pour redynamiser l'économie de montagne et ainsi éviter l'exode montagnard constaté depuis les années 40, le gouvernement français lance, en 1964, le “plan Neige”, avec pour but de concurrencer les grandes stations de sport d'hiver étrangères. Cette mesure ...
The present paper investigates numerically and theoretically the axisymmetric vortex breakdown occurring in a constricted pipe of infinite extension, i.e., the transition from a smooth columnar state to a breakdown state exhibiting a recirculation bubble. ...
Par sa position géographique, Damas est à la croisée de chemins millénaires. Qaboun précisément se situe à la porte de la ville, sur la trajectoire de l'autoroute Nord, de la future ligne de métro et de l'antique route d'Alep. La convergence en ce point de ...
Let F/E be a finite Galois extension of fields with abelian Galois group Γ. A self-dual normal basis for F/E is a normal basis with the additional property that TrF/E(g(x),h(x))=δg,h for g,h∈Γ. Bayer-Fluckiger and Lenstra h ...
We show that for any elliptic curve E(Fqn), if an adversary has access to a Static Diffie-Hellman Problem (Static DHP) oracle, then by making O(q1−n+11) Static DHP oracle queries during an initial learning phase, for fixed $n>1 ...
Let k be an algebraically closed field. Let P(X-11,...,X-nn, T) be the characteristic polynomial of the generic matrix (X-ij) over k. We determine its singular locus as well as the singular locus of its Galois splitting. If X is a smooth quasi-projective s ...
