Total ionizing dose effects on MOS and bipolar devices in the natural space radiation environment

Description: Mechanisms that control the response of MOS and bipolar devices to ionizing radiation in the natural space environment are briefly reviewed. Standard tests based on room-temperature irradiation and elevated temperature annealing are described for MOS devices to bound the effects of oxide and interface-trap charge in space. For bipolar devices that exhibit enhanced low-dose-rate sensitivity, a standard test equivalent to that developed for MOS devices is not available. However, screening techniq… more

Energy R&D in the United States

Description: In 1997, the US public and private sectors invested $205.7 billion in R and D. Private sector investments in R&D increased 34% between 1990 and 1997; over the same period the federal government decreased its expenditures by 15% in real terms. Projections of outyear federal budgets indicate the federal government will continue to reduce its investments in R&D for the foreseeable future. Defense R&D continues to be the largest area of concentration for federal government's R&D inv… more

Improved single sector supersymmetry breaking

Description: Building on recent work by N. Arkani-Hamed and the present authors, we construct realistic models that break supersymmetry dynamically and give rise to composite quarks and leptons, all in a single strongly-coupled sector. The most important improvement compared to earlier models is that the second-generation composite states correspond to dimension-2 ''meson'' operators in the ultraviolet. This leads to a higher scale for flavor physics, and gives a completely natural suppression of flavor-cha… more

Large N elliptic genus and AdS/CFT Correspondence

Description: According to one of Maldacena's dualities, type IIB string theory on AdS{sub 3} x S{sup 3} x K3 is equivalent to a certain N = (4, 4) superconformal field theory. In this note we compute the elliptic genus of the boundary theory in the supergravity approximation. A finite quantity is obtained once we introduce a particular exclusion principle. In the regime where the supergravity approximation is reliable, we find exact agreement with the elliptic genus of a sigma model with target space K3{sup… more

Performance of large-scale scientific applications on the IBM ASCI Blue-Pacific system

Description: The IBM ASCI Blue-Pacific System is a scalable, distributed/shared memory architecture designed to reach multi-teraflop performance. The IBM SP pieces together a large number of nodes, each having a modest number of processors. The system is designed to accommodate a mixed programming model as well as a pure message-passing paradigm. We examine a number of applications on this architecture and evaluate their performance and scalability.

Preliminary definition of geophysical regions for the Middle East and North Africa

Description: The ability to calibrate seismic stations to improve the monitoring of the Comprehensive Test Ban Treaty is partially limited by the availability of seismic events with known locations and source properties. To confidently extrapolate from these events to aseismic regions, and to properly account for discontinuities in seismic properties requires accurate geophysical models. This paper lays out a preliminary, first-order, regionalization of the Middle East and North African (MENA) region. The m… more

Laser damage performance of fused silica optical componets measured on the beamlet laser at 35nm

Description: A statistics-based model is being developed to predict the laser-damage-limited lifetime of UV optical components on the NIF laser. In order to provide data for the model, laser damage experiments were performed on the Beamlet laser system at LLNL (aperture: 34 cm x 34 cm). Three prototype NIF focus lenses were exposed to 351 nm pulses (1.5 ns or 3 ns) during four experimental campaigns, each consisting of 23 to 38 pulses at NIF relevant fluences. Each lens was sol-gel AR coated and all laser e… more

On the nature of the optimal control problem at leaking underground fuel tank sites

Description: In California, leaking underground fuel tank (LUFT) legislation was conceived because of concern that ''time bomb plumes'' would ultimately impact a significant portion of the state's ground and surface water resources. However, it has been found that fuel hydrocarbons (FHC) plumes are stable at relatively short distances from the source in areas of shallow groundwater. In urban areas, these shallow aquifers are not even recommended for use because they are subject to contamination from sewers,… more

Diet of Nesting Red-Cockaded Woodpecker at Three Locations

Description: The authors studied diets of nestling red-cockaded woodpeckers for two years on three sites in South Carolina and Georgia. Cameras recorded 33 different types of prey. Wood roaches were the most common, amounting to 50% of the prey. In addition, blueberries and saw fly larvae were collected by birds. Snail shells were also collected. Morista's index of diet overlap ranged from 0.94 to 0.99 for breeding males and females. We conclude that nestling diets are similar across the region.
