2-D Path Corrections for Local and Regional Coda Waves: A Test of Transportability (open access)

2-D Path Corrections for Local and Regional Coda Waves: A Test of Transportability

Reliable estimates of the seismic source spectrum are necessary for accurate magnitude, yield, and energy estimation. In particular, how seismic radiated energy scales with increasing earthquake size has been the focus of recent debate within the community and has direct implications on earthquake source physics studies as well as hazard mitigation. The 1-D coda methodology of Mayeda et al. [2003] has provided the lowest variance estimate of the source spectrum when compared against traditional approaches that use direct S-waves, thus making it ideal for networks that have sparse station distribution. The 1-D coda methodology has been mostly confined to regions of approximately uniform complexity. For larger, more geophysically complicated regions, 2-D path corrections may be required. We will compare performance of 1-D versus 2-D path corrections in a variety of regions. First, the complicated tectonics of the northern California region coupled with high quality broadband seismic data provides for an ideal ''apples-to-apples'' test of 1-D and 2-D path assumptions on direct waves and their coda. Next, we will compare results for the Italian Alps using high frequency data from the University of Genoa. For Northern California, we used the same station and event distribution and compared 1-D and 2-D path …

21st Century Challenges: Transforming Government to Meet Current and Emerging Challenges (open access)

21st Century Challenges: Transforming Government to Meet Current and Emerging Challenges

Testimony issued by the Government Accountability Office with an abstract that begins "The daunting challenges that face the nation in the 21st century establish the need for the transformation of government and demand fundamental changes in how federal agencies should meet these challenges by becoming flatter, more results-oriented, externally focused, partnership-oriented, and employee-enabling organizations. This testimony addresses how the long-term fiscal imbalance facing the United States, along with other significant trends and challenges, establish the case for change and the need to reexamine the base of the federal government; how federal agencies can transform into high-performing organizations; and how multiple approaches and selected initiatives can support the reexamination and transformation of the government and federal agencies to meet these 21st century challenges."

An Ab Initio Approach Towards Engineering Fischer-Tropsch Surface Chemistry (open access)

An Ab Initio Approach Towards Engineering Fischer-Tropsch Surface Chemistry

As petroleum prices continue to rise and the United States seeks to reduce its dependency on foreign oil, there is a renewed interest in the research and development of more efficient and alternative energy sources, such as fuel cells. One approach is to utilize processes that can produce long-chain hydrocarbons from other sources. One such reaction is Fischer-Tropsch synthesis. Fischer-Tropsch synthesis is a process by which syngas (CO and H{sub 2}) is converted to higher molecular weight hydrocarbons. The reaction involves a complex set of bond-breaking and bond-making reactions, such as CO and H{sub 2} activation, hydrocarbon hydrogenation reactions, and hydrocarbon coupling reactions. This report details our initial construction of an ab initio based kinetic Monte Carlo code that can be used to begin to simulate Fischer-Tropsch synthesis over model Co(0001) surfaces. The code is based on a stochastic kinetic formalism that allows us to explicitly track the transformation of all reactants, intermediates and products. The intrinsic kinetics for the simulations were derived from the ab initio results that we reported in previous year summaries.
