Louisiana Blue Ribbon Commission on Bayou Corne Safety

Secretary Stephen Chustz, from the Louisiana Department of Natural Resources (LADNR), asked David Borns (in Sandia’s Geotechnology and Engineering Dept.) to serve on the blue ribbon commission (BRC) that was formed by Governor Bobby Jindal to provide science-based public safety recommendations regarding the sinkhole in the Bayou Corne area. The BRC will help LADNR continue [...]

Estimating Device or System Probability of Failure

POF Darts is a new algorithm for the QMU problem of estimating device or system probability of failure (POF), e.g., of critical infrastructures in the face of a potentially disruptive event. POF Darts wraps around a computational simulation of a device, evaluating it at particular parameter values, such as uncertain environmental conditions and varying as-manufactured [...]

American Geophysical Union Publishes Hope Michelsen’s Induction to Alameda County Women’s Hall of Fame

The April 9 issue of EOS, Transactions of the American Geophysical Union, ran a news item in their “Geophysisicists Honors” section about Hope Michelsen’s (in the Combustion Chemistry Dept.) induction into the Alameda County Women’s Hall of Fame ([94(15), p 144], announced here in February). The American Geophysical Union is the world’s largest professional society for geophysicists [...]

Implemented “Vertically Lagrangian” Option in the Community Atmosphere Model

The Community Earth System Model (CESM) is a state-of-the-art global climate model being developed with the support of the National Science Foundation and the Department of Energy and used for climate-change science and assessments. Sandia has been leading a multilaboratory effort to develop a new “dynamical core” for CESM’s atmospheric component. This new dynamical core [...]

Sandia Quantum Transport Article Was the 12th Most Downloaded Paper from AIP’s Applied Physics Letters in February

Research on topological insulators (TIs) has drawn intensive interests. The type-II InAs/GaSb heterostructure, due to its unusual alignment of the conduction and valence band edges of InAs and GaSb, is predicted to be a two-dimensional (2D) TI. Historically, type-II InAs/GaSb heterostructures have been extensively studied for infrared applications. With the new prediction as a 2D [...]
