Source type estimation using noble gas samples.

A Bayesian source-term algorithm recently published by Eslinger et al. (2019) extended previous models by including the ability to discriminate between classes of releases such as nuclear explosions, nuclear power plants, or medical isotope production facilities when multiple isotopes are measured. Using 20 release cases from a synthetic data set previously published by Haas et al.

Waiting for a liver--hidden costs of the organ shortage.

Discussion about the economics of end-stage liver disease has typically focused on the high cost of liver transplantation, but the management of complications in patients waiting for an organ can also be very expensive. Our research considered the hypothesis that an increase in the number of organ grafts would decrease health care costs in patients with liver disease by eliminating the cost of waiting for an organ. We examined treatment costs for a consecutive series of liver transplant candidates listed at our institution between November 1, 1996 and December 31, 1997.
