first principles modeling of nonlinear incidence rates in seasonal epidemics.	in this paper we used a general stochastic processes framework to derive from first principles the incidence rate function that characterizes epidemic models. we investigate a particular case, the liu-hethcote-van den driessche's (lhd) incidence rate function, which results from modeling the number of successful transmission encounters as a pure birth process. this derivation also takes into account heterogeneity in the population with regard to the per individual transmission probability. we ad ...	2011	21379320
the etiology of pneumonia in malnourished and well-nourished gambian children.	during a 2-year period 159 malnourished children ages 3 months to 5 years with radiologic evidence of pneumonia were investigated to determine the cause of their pneumonia. in addition 119 malnourished children without pneumonia, 119 well-nourished children with pneumonia and 52 well-nourished children without pneumonia were studied as controls. percutaneous lung aspiration was performed on 35 malnourished and 59 well-nourished children with pneumonia. bacteria were isolated from the blood, lung ...	1994	7845751
