background nafld/nash is a manifestation of metabolic syndrome and is associated with obesity/overweight. not all obese/overweight individuals develop nash. gastro-esophageal reflux disease (gerd) is considered a gastrointestinal manifestation of the metabolic syndrome and is associated with obesity/overweight. again not all obese/overweight individuals develop gerd. recent data show associatio...

Nonalcoholic fatty liver disease (NAFLD) is increasing in pediatric age group parallel to the growing prevalence of obesity and overweight all around the world. So changing in life style and   interventions on obesogenic environment is cornerstone of NAFLD therapy in obese children. Some experts recommend that children and adolescents be encouraged to follow a low-fat, low-glycemic-index diet t...

We give a novel proof of the existence of Nash equilibria in all finite games without using fixed point theorems or path following arguments. Our approach relies on a new notion intermediate between Nash and correlated equilibria called exchangeable equilibria, which are correlated equilibria with certain symmetry and factorization properties. We prove these exist by a duality argument, using H...

The h-cobordism theorem is a noted theorem in differential and PL topology. A generalization of the h-cobordism theorem for possibly non simply connected manifolds is the so called s-cobordism theorem. In this paper, we prove semialgebraic and Nash versions of these theorems. That is, starting with semialgebraic or Nash cobordism data, we get a semialgebraic homeomorphism (respectively a Nash d...

We study the connection between the evolutionary replicator dynamics and the number of Nash equilibria in large random bi-matrix games. Using techniques of disordered systems theory we compute the statistical properties of both, the fixed points of the dynamics and the Nash equilibria. Except for the special case of zero-sum games one finds a transition as a function of the so-called co-operati...
