A letter report issued by the Government Accountability Office with an abstract that begins "International flights bound for the United States continue to be targets of terrorist activity, as demonstrated by the October 2010 discovery of explosive devices in air cargo packages bound for the United States from Yemen. The Transportation Security Administration (TSA) is responsible for securing the nation's civil aviation system, which includes ensuring the security of U.S.-bound flights. As requested, GAO evaluated (1) the steps TSA has taken to enhance its foreign airport assessment program since 2007, and any remaining program challenges; (2) TSA's assessment results, including how TSA uses the results to guide future efforts; and (3) what opportunities, if any, exist to enhance the program. To conduct this work, GAO reviewed foreign airport assessment procedures and results, interviewed TSA and foreign aviation security officials, and observed TSA conduct a foreign airport assessment. While these interviews and observations are not generalizable, they provided insights on TSA's program. This is the public version of a sensitive report GAO issued in September, 2011. Information that TSA deemed sensitive has been omitted."

The design and performance optimization of particle accelerators are essential for the success of the DOE scientific program in the next decade. Particle accelerators are very complex systems whose accurate description involves a large number of degrees of freedom and requires the inclusion of many physics processes. Building on the success of the SciDAC-1 Accelerator Science and Technology project, the SciDAC-2 Community Petascale Project for Accelerator Science and Simulation (ComPASS) is developing a comprehensive set of interoperable components for beam dynamics, electromagnetics, electron cooling, and laser/plasma acceleration modelling. ComPASS is providing accelerator scientists the tools required to enable the necessary accelerator simulation paradigm shift from high-fidelity single physics process modeling (covered under SciDAC1) to high-fidelity multiphysics modeling. Our computational frameworks have been used to model the behavior of a large number of accelerators and accelerator R&D experiments, assisting both their design and performance optimization. As parallel computational applications, the ComPASS codes have been shown to make effective use of thousands of processors.
