two different growth media, namely complex and defined media, were used to examine establishment of steady-state conditions in phosphate-limited culture system of saccharomyces cerevisiae cen.pk113-5d strain. using the defined growth medium, it was possible to obtain steady state condition in the continuous culture. the effect of phosphate concentration on the growth of s. cerevisiae in phospha...

We consider the problem of rate–R channel coding with causal/non–causal side information at the transmitter, under an additional requirement of minimizing the amount of information that can be learned from the channel output about the state sequence, which is defined in terms of the equivocation E (i.e., the mutual information between the state sequence and the channel output sequence). A singl...

CONTEXT Unintended pregnancy is a key reproductive health indicator, but rates have never been calculated for all 50 states. METHODS State-level estimates of unintended pregnancy rates in 2006 were calculated using data from several sources. The proportion of births resulting from unintended pregnancies was obtained from the Pregnancy Risk Assessment Monitoring System and similar state survey...
