A publication issued by the Government Accountability Office with an abstract that begins "This testimony discusses the effects of the recent recession on older adults. While the recession officially ended in June 2009, our economy has experienced a weak recovery, with unemployment still above 9 percent. Older adults--particularly those close to or in retirement--may not have the same opportunities as younger adults to recover from the recession's effects. For example, older adults--generally those 55 and older--may have insufficient time to rebuild their depleted retirement savings due to sharp declines in financial markets and home equity, and increased medical costs. Further, while older workers are less likely to be unemployed than workers in younger age groups, when older workers lose a job they are less likely to find other employment. These changes have intensified older adults' concerns about having sufficient savings now and adequate income throughout retirement. Social Security forms the foundation of income for nearly all retiree households, providing 36 percent of aggregate income for households with a member aged 65 and older; however, it provides a much greater portion of income for low and middle income households. Pensions and assets together provide 31 percent of aggregate income. However, many …

A publication issued by the Government Accountability Office with an abstract that begins "Over the last 10 fiscal years, federal agencies have increased their spending on construction contracts, leading to obligations of almost $54 billion in fiscal year 2010. When awarding contracts, the Federal Acquisition Regulation (FAR) requires agencies to consider firms' performance records to help ensure that taxpayer dollars go to capable contractors. The FAR also provides agencies with broad discretion in deciding how they will consider firms' prior experience, which refers to whether the firms have done similar work before, and past performance, which describes how well they have done that work. As construction firms without prior federal contracting experience seek to gain entry into the federal marketplace, some may regard the consideration of these factors as an impediment. In response to your request for information on the consideration of prior experience and past performance, we reviewed (1) how selected agencies consider prior experience and past performance in awarding construction contracts and (2) the resources available to assist firms in gaining entry to the federal marketplace."

The LOCO algorithm has been used by many accelerators around the world. Although the uses for LOCO vary, the most common use has been to find calibration errors and correct the optics functions. The light source community in particular has made extensive use of the LOCO algorithms to tightly control the beta function and coupling. Maintaining high quality beam parameters requires constant attention so a relatively large effort was put into software development for the LOCO application. The LOCO code was originally written in FORTRAN. This code worked fine but it was somewhat awkward to use. For instance, the FORTRAN code itself did not calculate the model response matrix. It required a separate modeling code such as MAD to calculate the model matrix then one manually loads the data into the LOCO code. As the number of people interested in LOCO grew, it required making it easier to use. The decision to port LOCO to Matlab was relatively easy. It's best to use a matrix programming language with good graphics capability; Matlab was also being used for high level machine control; and the accelerator modeling code AT, [5], was already developed for Matlab. Since LOCO requires collecting and processing a …

The following work has been performed by PI Hans De Sterck and graduate student Manda Winlaw for the required tasks 1-5 (as listed in the Statement of Work). Graduate student Manda Winlaw has visited LLNL January 31-March 11, 2011 and May 23-August 19, 2010, working with Van Henson and Mike O'Hara on non-negative matrix factorizations (NMF). She has investigated the dense subgraph clustering algorithm from 'Finding Dense Subgraphs for Sparse Undirected, Directed, and Bipartite Graphs' by Chen and Saad, testing this method on several term-document matrices and adapting it to cluster based on the rank of the subgraphs instead of the density. Manda Winlaw was awarded a first prize in the annual LLNL summer student poster competition for a poster on her NMF research. PI Hans De Sterck has developed a new adaptive algebraic multigrid algorithm for computing a few dominant or minimal singular triplets of sparse rectangular matrices. This work builds on adaptive algebraic multigrid methods that were further developed by the PI and collaborators (including Sanders and Henson) for Markov chains. The method also combines and extends existing multigrid algorithms for the symmetric eigenproblem. The PI has visited LLNL February 22-25, 2011, and has given a CASC seminar …

Cross sections for compound-nuclear reactions play an important role in models of astrophysical environments and simulations of the nuclear fuel cycle. Providing reliable cross section data remains a formidable task, and direct measurements have to be complemented by theoretical predictions and indirect methods. The surrogate nuclear reactions method provides an indirect approach for determining cross sections for reactions on unstable isotopes, which are difficult or impossible to measure otherwise. Current implementations of the method provide useful cross sections for (n,f) reactions, but need to be improved upon for applications to capture reactions.

The Source Physics Experiment (SPE) is planning a 1000 kg (TNT equivalent) shot (SPE2) at the Nevada National Security Site (NNSS) in a granite borehole at a depth (canister centroid) of 45 meters. This shot follows an earlier shot of 100 kg in the same borehole at a depth 60 m. Surrounding the shotpoint is an extensive array of seismic sensors arrayed in 5 radial lines extending out 2 km to the north and east and approximately 10-15 to the south and west. Prior to SPE1, simulations using a finite difference code and a 3D numerical model based on the geologic setting were conducted, which predicted higher amplitudes to the south and east in the alluvium of Yucca Flat along with significant energy on the transverse components caused by scattering within the 3D volume along with some contribution by topographic scattering. Observations from the SPE1 shot largely confirmed these predictions although the ratio of transverse energy relative to the vertical and radial components was in general larger than predicted. A new set of simulations has been conducted for the upcoming SPE2 shot. These include improvements to the velocity model based on SPE1 observations as well as new capabilities added to …

This report discusses the current state of Bahrain, which has undergone substantial political reforms since the late 1990s, but which still suffers from tension between the Shiite majority and the Sunni-led government. This report focuses particularly on Bahrain's relationship with Iran and Bahrain's relationship with the United States.
