In this paper, we are interested in linearization techniques for exact resolution of the Unconstrained Quadratic (0-1) Problem. Our purpose is to propose " economical " linear formulations. We first extend the current techniques in a general linearization framework containing many other schemes and propose a new linear formulation. Numerical results(More)
INTRODUCTION Noncommunicable diseases (NCDs) are a major public health threat, particularly in developing countries. In sub-Saharan Africa, the scarcity of reliable data on NCDs in the general population makes it difficult to develop efficient prevention strategies. The objective of this cross-sectional study was to assess the prevalence of 4(More)
Encapsulating peritoneal sclerosis (EPS) is a rare but potentially lethal complication of peritoneal dialysis (PD). Peritoneal tuberculosis is considered an etiologic factor. We report a case of EPS in a 40-year-old man who was switched to hemodialysis because of peritoneal tuberculosis after 2 years of PD. Because of the persistence of gastrointestinal(More)
This paper presents an exact solution method based on a new linearization scheme for the 0-1 Quadratic Knapsack Problem (QKP) which consists of maximizing a quadratic pseudo-Boolean function with non negative coefficients subject to a linear capacity constraint. Contrasting to traditional linearization schemes, our approach only adds one extra variable. We(More)
Autosomal polycystic kidney disease (ADPKD) is a genetic disorder with two causal PKD-1 and PKD-2. Genetic studies have demonstrated an important allelic variability between patients but few data are known about genetic variants in African populations. We report a new mutation found in a 41-year old women with mild chronic kidney disease secondary to ADPKD.(More)
