This paper presents a multiobjective evolutionary algorithm to optimize radial basis function neural networks (RBFNNs) in order to approach target functions from a set of input-output pairs. The procedure allows the application of heuristics to improve the solution of the problem at hand by including some new genetic operators in the evolutionary process.(More)
BACKGROUND The heterotrimeric Gα protein Pga1-mediated signaling pathway regulates the entire developmental program in Penicillium chrysogenum, from spore germination to the formation of conidia. In addition it participates in the regulation of penicillin biosynthesis. We aimed to advance the understanding of this key signaling pathway using a proteomics(More)
OBJECTIVE Staff in pediatric intensive care units (PICU) are inherently exposed to potentially traumatic events. Posttraumatic growth (PTG) is the occurrence of positive changes after experiencing a traumatic event. This study aims (a) to evaluate the prevalence of PTG in PICU staff, and whether their scores are different from those reported by(More)
The mutant Penicillium chrysogenum strain dogR5, derived from strain AS-P-78, does not respond to glucose regulation of penicillin biosynthesis and β-galactosidase, and is partially deficient in D-glucose phosphorilating activity. We have transformed strain dogR5 with the (hexokinase) hxk2 gene from Saccharomyces cerevisiae. Transformants recovered glucose(More)
This research addresses the need of adolescents with motor disabilities to increase their social relationships and how through induced volunteerism peers can provide that assistance. Participants were 30 motor disabled adolescents (20 males and 10 females) and 35 non-disabled volunteer adolescents (27 females and 8 males), all of them high school students(More)
