OBJECTIVES Here, we used statistical excess mortality models to estimate the burden of seasonal and pandemic influenza in China. (More)
BACKGROUND Male reproductive toxicity induced by exposure to bisphenol A (BPA) has been widely reported. The testes have proven to be a major target organ of BPA toxicity, so studying testicular metabolite variation holds promise for the discovery of mechanisms linked to the toxic effects of BPA on reproduction. METHODOLOGY/PRINCIPAL FINDINGS Male(More)
In this paper, an entropy-based method is proposed to forecast the demographical changes of countries. We formulate the estimation of future demographical profiles as a constrained optimization problem, anchored on the empirically validated assumption that the entropy of age distribution is increasing in time. The procedure of the proposed method involves(More)
