Awards

Livermore researchers Kenneth Bogen and Edwin Jones of the Energy and Environment Directorate received the 2006 Best Paper for Risk Analysis Award in the decision sciences category from the Society for Risk Analysis. The award-winning paper, “Risks of Mortality and Morbidity from Worldwide Terrorism: 1968–2004,” appeared in the February 2006 issue of Risk Analysis.
In analyzing 36 years of data, Bogen and Jones found that terrorism casualty patterns exhibit the same type of rare-event (worst-case) behavior as many types of extreme physical phenomena. With this information, they also estimated the lifetime risks of injury and death from terrorism events in different world regions.

A team of Laboratory researchers received the Best Application Paper Award at the 2006 Visualization Conference held in Baltimore, Maryland, by the Institute of Electrical and Electronics Engineers. The winning paper, “Understanding the Structure of the Turbulent Mixing Layer in Hydrodynamic Instabilities,” was coauthored by Valerio Pascucci, Daniel Laney, Peer-Timo Bremer, and Ajith Mascarenhas of the Center for Applied Scientific Computing and William Cabot, Andrew Cook, and Paul Miller of the Defense and Nuclear Technologies Directorate. In this study, the researchers used Morse theoretical techniques to extract bubblelike features from a large data set produced in a hydrodynamics simulation conducted on Livermore’s BlueGene/L supercomputer. The new technique allowed them to analyze the complex topology that occurs in Rayleigh–Taylor mixing, which may play a central role in hydrodynamic instability.
