There has been a great collective effort in the search for perceptually meaningful sound transformation techniques. The transformation of sounds matching target sound descriptors is a promising candidate because the descriptors are thought to capture timbral dimensions corresponding to relevant perceptual features. However, matching the descriptors alone is not enough because there are a large ...

We investigate a model of evolutionary dynamics on a smooth landscape which features a “mutator” allele whose effect is to increase the mutation rate. We show that the expected proportion of mutators far from equilibrium, when the fitness is steadily increasing in time, is governed solely by the transition rates into and out of the mutator state. This results is a much faster rate of fitness in...

As of April 2007, Griffin P. Rodgers has taken over as director of the NIDDK, but had been the deputy director under Allen Spiegel since 2001 and the chief of Hematology since 1998. The JCI took the opportunity to ask this career investigator in the NIH about his goals and visions for the NIDDK. JCI: You moved quickly from chief of Hematology to deputy director of the NIDDK to director — what d...

this research is a new attempt in order to study the effect of evolution theory in the dimension of empirical ethics. in the contemporary area the evolutionary ethics is in the three branches: descriptive, prescriptive and meta-ethics. the descriptive evolutionary ethics tries to modify human’s ethical believes in the evolutionary aspect and achieves more share from two others part in this grou...
