This paper defends the use of evolutionary algorithms to generate (and evolve) strategies that manage the behavior of a team in simulated football videogames. The chosen framework to develop the experiments is Robocup, an internatonal project that promotes the use of Artificial Intelligence in socially significant areas. One of these areas is related to computer games in the form of a simulated...

It has been suggested that early screening and intervention in this at-risk population be a priority. HYPOTHESIS Omega-3 essential fatty acid has been shown to improve cardiovascular lipid risk f...

CONTEXT Excessive fat mass clearly has adverse effects on metabolic processes that can ultimately lead to the development of chronic disease. Early identification of high-risk status may facilitate referral for definitive diagnostic tests and implementation of interventions to reduce cardiometabolic risk. OBJECTIVE To document the prevalence of metabolic syndrome among collegiate football pla...
