C57Bl/6J and BALB/cAnN inbred strains of mice differed significantly in mortality and symptoms when intoxicated subcutaneously with one LD(50) of venom from Centruroides limpidus limpidus. Higher mortality was observed in C57Bl/6J than in BALB/cAnN. Also, C57Bl/6J mice more quickly developed muscular and respiratory collapse whilst BALB/cAnN mice were(More)
The time spent by users are almost two or more hours looking for papers that generates the possibility to make a search engine to optimize and precision in the results. This works purposes a better classification of research papers, the architecture works with a database of knowledge related with the topics of programming, databases and operating systems.(More)
—Evolutionary computation is a generic term used to make reference to the solution of computational problems planned and implemented based on models of an evolutionary process. Most of the evolutionary algorithms propose biological paradigms, and the concepts of natural selection, mutation and reproduction. However, other paradigms that can be adopted in(More)
Many problems involve not structured environments which can be solved from the perspective of particle swarm optimization (PSO). In this research analyze the voting behavior in a popular song contest held every year in Europe. The dataset makes it possible to analyze the determinants of success, and gives a rare opportunity to run a direct test of vote(More)
Mortality rates of mice and their levels of anti-venom and anti-F(ab')2 antibodies were assessed after three episodes of subcutaneous envenomations with or without treatment with horse F(ab')2. Soluble venom from the Mexican scorpion Centruroides limpidus limpidus was used for these experiments. Repetition of episodes did not induce different mortality(More)
This paper presents an improvement in the process of diversification of populations in the genetic algorithms using immigration and an appropriate selection of operators. The proposal significantly enhance the quality of solutions obtained, because it prevents premature convergence like result from the loss of diversity in the genetic material of(More)
