From March 1990 to May 1993,309 patients underwent redo cardiac surgery
operation at the Shahid Rajai Heart Hospital in Tehran. Early mortality rates in
these patients showed a significant increase in comparison to patients undergoing
open heart surgery for the first time. Late mortality (at least one month after
surgery) in the patients was slightly increased also but less than early morta...
This article proposes a stochastic model, which captures mortality correlations across countries and common mortality shocks, for analyzing catastrophe mortality contingent claims. To estimate our model, we apply particle filtering, a general technique that has wide applications in non-Gaussian and multivariate jump-diffusion models and models with nonanalytic observation equations. In addition...

Managers are often concerned about oak mortality in maturing mixed-oak forests, but they often lack explicit information about mortality risk for oaks that differ in species, size, crown class, competitive status, and growth rate. In eastern North America, tree species in the red oak group (Quercus Section Lobatae) are typically shorter lived than those in the white oak group (Section Quercus),...
