The idea that diversity in the population of a genetic algorithm affects the algorithm’s search efficiency is widely accepted. However, little is known about the amount of node level diversity present in Genetic Programming (GP) runs. In this paper, we introduce several techniques for measuring the diversity of a population based on the genetic history of the individuals. We then apply these me...

Aspergillus fumigatus is a ubiquitous opportunistic fungal pathogen capable of causing invasive aspergillosis, a globally distributed disease with a mortality rate of up to 90% in high-risk populations. Effective control and prevention of this disease require a thorough understanding of its epidemiology. However, despite significant efforts, the global molecular epidemiology of A. fumigatus rem...

nuclear markers such as microsatellites have allowed the identification of conservation and management populations of the hawksbill turtles. in present study, eight microsatellite loci were studied. 60 samples of hawksbill turtles. flipper from shidvar and hormuz islands have been surgically removed and preserved in 20% dmso buffer. dna was extracted using dnp kit and amplified by pcr methods. ...

CYP2C19 polymorphism is associated with pretreatment drug response prediction, metabolism, and disposition. Pakistan consists of a population comprising of various ethnic groups residing in different regions of the country each claiming diverse ethnic origins. The identification of CYP450 genotypic composition of these populations is therefore necessary to avoid adverse drug reactions in these ...
