Physiochemical Evidence of Faulting Processes and Modeling of Fluid in Evolving Fault Systems in Southern California

Description: Our study targets recent (Plio-Pleistocene) faults and young (Tertiary) petroleum fields in southern California. Faults include the Refugio Fault in the Transverse Ranges, the Ellwood Fault in the Santa Barbara Channel, and most recently the Newport- Inglewood in the Los Angeles Basin. Subsurface core and tubing scale samples, outcrop samples, well logs, reservoir properties, pore pressures, fluid compositions, and published structural-seismic sections have been used to characterize the tectonic/diagenetic history of the faults. As part of the effort to understand the diagenetic processes within these fault zones, we have studied analogous processes of rapid carbonate precipitation (scaling) in petroleum reservoir tubing and manmade tunnels. From this, we have identified geochemical signatures in carbonate that characterize rapid CO2 degassing. These data provide constraints for finite element models that predict fluid pressures, multiphase flow patterns, rates and patterns of deformation, subsurface temperatures and heat flow, and geochemistry associated with large fault systems.

Final Report: Stability and Novel Properties of Magnetic Materials and Ferromagnet / Insulator Interfaces

Description: We report investigations of the synthesis, structure, and properties of new materials for spintronic applications integrated onto silicon substrates. Our primary focus is materials with very high, negative, intrinsic spin polarization of the density of states at the Fermi level. We have developed a new synthesis method for Fe3O4 thin films through selective oxidation of Fe, resulting in smooth, low-defect density films. We have synthesized Fe4N films and shown that they preferentially oxidize to Fe3O4. When integrated into magnetic tunnel junctions consisting of Fe4N / AlOx / Fe, oxidation at the Fe4N / AlOx interface creates Fe3O4, leading to negative tunneling magnetoresistance (TMR). Oxidation of Fe in nominally symmetric CoFe / AlOx / CoFe also produces Fe3O4 and negative TMR under selected oxidation conditions.

LEEM investigations of clean surfaces driven by energetic ion beams

Description: The original purpose of this award was to use low‐energy electron microscopy (LEEM) to explore the dynamics of surfaces of clean single crystal surfaces when driven by a beam of energetic ions. The goal was to understand the nanoscience of hyperthermal growth, surface erosion by sublimation and irradiation, operation of surface sinks in irradiated materials, diffusion on driven surfaces, and the creation of structural patterns. This project was based on a novel LEEM system constructed by C. P. Flynn, which provided real‐time imaging of surface dynamics by scattering low energy electrons. With the passing of Prof. Flynn in late 2011, this project was completed under a slightly different scope by constructing a low‐energy, inelastic electron scattering (�EELS�) instrument. Consistent with Flynn�s original objectives for his LEEM system, this device probes the dynamics of crystal surfaces. However the measurements are not carried out in real time, but instead are done in the frequency domain, through the energy lost from the probe electrons. The purpose of this device is to study the collective bosonic excitations in a variety of materials, including high temperature superconductors, topological insulators, carbon allotropes including (but not limited to) graphene, etc. The ultimate goal here is to identify the bosons that mediate interactions in these and other materials, with hopes of shedding light on the origin of many exotic phenomena including high temperature superconductivity. We completed the construction of a low‐energy EELS system that operates with an electron kinetic energy of 7 - 10 eV. With this instrument now running, we hope to identify, among other things, the bosons that mediate pairing in high temperature superconductors. Using this instrument, we have already made our first discovery. Studying freshly cleaved single crystals of Bi{sub 2}Se{sub 3}, which is a topological insulator, we have observed a surface excitation at an ...

U.S.-Mexico Border: CBP Action Needed to Improve Wait Time Data and Measure Outcomes of Trade Facilitation Efforts

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Within the Department of Homeland Security (DHS), U.S. Customs and Border Protection's (CBP) data on commercial vehicle wait times--the time it takes to travel from the end of the queue to the CBP primary inspection point at land border crossings--are unreliable for public reporting and CBP management decisions across border crossings. These data--which are collected manually by CBP officers--are unreliable because CBP officers inconsistently implement an approved data collection methodology, and the methodologies used vary by crossing. For example, five of the six crossings GAO visited require observation of the end of the queue to estimate wait times, but officials at these crossings reported the lines extended beyond their view at times. As a result, these data are generally not used by the private sector and are of limited usefulness for CBP management decisions on staffing and infrastructure investments. Determining and taking steps to help CBP officials overcome challenges to consistent implementation of existing methodologies could improve the reliability and usefulness of CBP's current wait time data. CBP officials have identified automated wait time data collection technology as the best way to improve data reliability. The Department of Transportation (DOT), in coordination with state DOTs and CBP, has ongoing pilot projects to use technology to gather more reliable wait time data at some border crossings. However, CBP has not assessed the feasibility of replacing current methods with automated data collection. Doing so, consistent with program management standards, could help CBP determine how to best improve data reliability."

Biomedical Research: NIH Should Assess the Impact of Growth in Indirect Costs on Its Mission

Description: A letter report issued by the Government Accountability Office with an abstract that begins "From fiscal year 2002 to fiscal year 2012, indirect cost reimbursements from the National Institutes of Health (NIH) to universities increased slightly faster than those for direct costs, but increased notably faster during some periods. Specifically, from fiscal years 2002 to 2012, indirect costs increased 28.1 percent while direct costs increased 27.0 percent. However, for the fiscal years 2003 to 2012, indirect costs increased notably faster than direct costs, at 16.9 percent and 11.7 percent, respectively. In more recent years, annual changes were generally small but consistent. This increase occurred during a time when growth in NIH's budget for extramural research slowed to 5 percent from fiscal years 2008 to 2012, compared to about 21 percent from fiscal years 2002 to 2007. In fiscal year 2012, about 10 percent of the universities (50 out of about 500) receiving NIH extramural research funding received almost 70 percent of all indirect cost reimbursement provided to universities. Higher indirect cost rates tended to be associated with universities located in high-cost-of-living areas and privately owned universities."

Spectrum Management: Preliminary Findings on Federal Relocation Costs and Auction Revenues

Description: Testimony issued by the Government Accountability Office with an abstract that begins "Actual costs to relocate federal users from the 1710-1755 megahertz (MHz) band have exceeded the original $1 billion estimate by about $474 million as of March 2013, although auction revenues appear to exceed relocation costs by over $5 billion. Actual relocation costs exceed estimated costs for various reasons, including unforeseen challenges and some agencies not following the National Telecommunications and Information Administration's (NTIA) guidance for preparing the cost estimate. In contrast, the Department of Defense (DOD) expects to complete relocation for about $275 million or approximately $80 million less than its $355 million estimate. According to DOD officials, the relocation of systems from this band has been less expensive than originally estimated because many systems were simply re-tuned to operate in the adjacent 1755-1850 MHz band. The auction of the 1710-1755 MHz band raised almost $6.9 billion in gross winning bids. NTIA expects agencies to complete the relocation effort between 2013 and 2017; therefore, final net auction revenue (auction revenue less relocation costs) may change."

Indian Affairs: Better Management and Accountability Needed to Improve Indian Education

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Students in Bureau of Indian Education (BIE) schools perform consistently below Indian students in public schools on national and state assessments. For example, based on estimates from a 2011 study using national assessment data, in 4th grade, BIE students on average scored 22 points lower for reading and 14 points lower for math than Indian students attending public schools. The gap in scores is even wider when the average for BIE students is compared to the national average for non-Indian students. Additionally, the high school graduation rate for BIE students in 2011 was 61 percent, placing BIE in the bottom half among graduation rates for Indian students attending public schools in states where BIE schools are located."
