BACKGROUND More than 90 weak D types have been discovered to date. As there are no published data on the frequencies of weak D types in the Tunisian population, the aim of this study was to determine the composition of weak D alleles in our population. MATERIAL AND METHODS Blood samples from 1777 D+ and 223 D- blood donors were tested for markers 809G, 1154C, 8G, 602G, 667G, 446A, and 885T re...

We study nonsmooth multiobjective programming problems involving locally Lipschitz functions and support functions. Two types of Karush-Kuhn-Tucker optimality conditions with support functions are introduced. Sufficient optimality conditions are presented by using generalized convexity and certain regularity conditions. We formulate Wolfe-type dual and Mond-Weirtype dual problems for our nonsmo...

In the first part of this talk (two weeks ago), I sketched my work on the lattice theory of the weak order. The key point was that the lattice structure provides an alternate algebraic structure on a finite Coxeter group. One interesting aspect of this alternate structure is the study of quotients of the weak order modulo lattice congruences. The talk will start with a very brief recap of the r...

In this paper, we introduce a new class of generalized dI-univexity in which each component of the objective and constraint functions is directionally differentiable in its own direction di for a nondifferentiable multiobjective programming problem. Based upon these generalized functions, sufficient optimality conditions are established for a feasible point to be efficient and properly efficien...

In this article we study semi-abelian analogues of Schanuel conjecture. As showed by the first author, conjecture is equivalent to Generalized Period applied 1-motives without abelian part. Extending her methods, second, third and fourth authors have introduced analogue as toric a result paper, define 1-motives. C. Cheng et al. proved that implies algebraic independence values iterated exponent...

We define the notion of weak relative pseudo-complement on meet semi-lattices, and we show that it is strictly weaker than relative pseudo-complementation, but stronger than pseudo-complementation. Our main result is that if a complete lattice L is meet-continuous, then every closure operator on L admits weak relative pseudo-complements with respect to continuous closure operators on L.

This package computes relative risks for both prospective and retrospective samples using GLM and Logit-Log transformations. It will always produce relative risk estimates, although it may fail sometimes to produce confidence intervals.
