a two-year laboratory study on the biology (including self-fertilization) of bulinus truncatus, the intermediate host of schistosoma haematobium, s. bovis and paramphistomum microbotrium in iran, has revealed information on the longevity, reproduction, hatchability rate, hatching time during various months of the year, and growth and mortality rates of this snail. it was found that the reproduc...

We study the problem of maximizing population transfer efficiency in STIRAP system for case where dissipation rate intermediate state is much higher than maximum amplitude control fields. Under this assumption, original three-level can be reduced to a couple equations involving initial and target states only. find fields which maximize given duration $T$, without using any penalty lossy state, ...
