Mixed Electromagnetic and Circuit Simulations using a Higher-Order Hybrid Formulation
Standard surface impedance approximations are invalid at lower frequencies approaching DC since the cross sections of conductors are smaller than the skin depth. Hence, a volumetric formulation is typically used at these low frequencies for broadband simulation as necessitated in digital or ultra-wideband systems since the skin effect can be modeled explicitly. This modeling requires fine and frequency dependent volume meshing. However, an approach using higher-order elements and/or bases may alleviate these requirements. The intent of this paper is to present a tightly coupled circuit and hybrid boundary element (or integral equation)/finite element based electromagnetic simulation that has been coded in EIGER.

Implications of structural genomics target selection strategies: Pfam5000, whole genome, and random approaches
The structural genomics project is an international effort to determine the three-dimensional shapes of all important biological macromolecules, with a primary focus on proteins. Target proteins should be selected according to a strategy which is medically and biologically relevant, of good value, and tractable. As an option to consider, we present the Pfam5000 strategy, which involves selecting the 5000 most important families from the Pfam database as sources for targets. We compare the Pfam5000 strategy to several other proposed strategies that would require similar numbers of targets. These include including complete solution of several small to moderately sized bacterial proteomes, partial coverage of the human proteome, and random selection of approximately 5000 targets from sequenced genomes. We measure the impact that successful implementation of these strategies would have upon structural interpretation of the proteins in Swiss-Prot, TrEMBL, and 131 complete proteomes (including 10 of eukaryotes) from the Proteome Analysis database at EBI. Solving the structures of proteins from the 5000 largest Pfam families would allow accurate fold assignment for approximately 68 percent of all prokaryotic proteins (covering 59 percent of residues) and 61 percent of eukaryotic proteins (40 percent of residues). More fine-grained coverage which would allow accurate modeling of …

Fluorescent CdSe/ZnS nanocrystal-peptide conjugates for long-term, nontoxic imaging and nuclear targeting in living cells
One of the biggest challenges in cell biology is the imaging of living cells. For this purpose, the most commonly used visualization tool is fluorescent markers. However, conventional labels, such as organic fluorescent dyes or green fluorescent proteins (GFP), lack the photostability to allow the tracking of cellular events that happen over minutes to days. In addition, they are either toxic to cells (dyes), or difficult to construct and manipulate (GFP). We report here the use of a new class of fluorescent labels, silanized CdSe/ZnS nanocrystal-peptide conjugates, for imaging the nuclei of living cells. CdSe/ZnS nanocrystals, or so called quantum dots (qdots), are extremely photostable, and have been used extensively in cellular imaging of fixed cells. However, most of the studies about living cells so far have been concerned only with particle entry into the cytoplasm or the localization of receptors on the cell membrane. Specific targeting of qdots to the nucleus of living cells ha s not been reported in previous studies, due to the lack of a targeting mechanism and proper particle size. Here we demonstrate for the first time the construction of a CdSe/ZnS nanocrystal-peptide conjugate that carries the SV40 large T antigen nuclear localization signal (NLS), …

COAMPS Application to Global and Homeland Security Threat Problems
Atmospheric dispersion problems have received more attention with regard to global and homeland security than their conventional roles in air pollution and local hazard assessment in the post 9/11 era. Consequently, there is growing interest to characterize meteorology uncertainty at both low and high altitudes (below and above 30 km, respectively). A 3-D Coupled Ocean Atmosphere Prediction System (COAMPS, developed by Naval Research Laboratory; Hodur, 1997) is used to address LLNL's task. The objective of this report is focused on the effort at the improvement of COAMPS forecast to address the uncertainty issue, and to provide new capability for high-altitude forecast. To assess the atmospheric dispersion behavior in a wider range of meteorological conditions and to expand its vertical scope for the potential threat at high altitudes, several modifications of COAMPS are needed to meet the project goal. These improvements include (1) the long-range forecast capability to show the variability of meteorological conditions at a much larger time scale (say, a year), and (2) the model physics enhancement to provide new capability for high-altitude forecast.

UDEC simulation of Triaxial Testing of Lithophysal Tuff
The current conceptual design for the proposed nuclear waste repository at Yucca Mountain Nevada includes placing most of the facility in lithophysal Tuff. Because it is difficult to conduct standard confined triaxial laboratory tests on lithophysal tuff, it was decided to use UDEC to conduct numerical triaxial testing of simulated lithophysal tuff samples to supplement existing uniaxial compression data. The results of these numerical experiments are intended to provide guidance on the variability of physical properties as a function of lithophysal porosity. These data can then be used as a basis for large scale modeling of the behavior of the repository drifts. The results of the numerical testing were encouraging and show consistent trends in tuff strength and overall performance as a function of lithophysal porosity.

Determining neutron capture cross sections with the Surrogate Reaction Technique: Measuring decay probabilities with STARS
Neutron-induced reaction cross sections are sometimes difficult to measure due to target or beam limitations. For two-step reactions proceeding through an equilibrated intermediate state, an alternate ''surrogate reaction'' technique can be applicable, and is currently undergoing investigation at LLNL. Measured decay probabilities for the intermediate nucleus formed in a light-ion reaction can be combined with optical-model calculations for the formation of the same intermediate nucleus via the neutron-induced reaction. The result is an estimation for overall (n,{gamma}/n/2n) cross sections. As a benchmark, the reaction {sup 92}Zr({alpha},{alpha}'), surrogate, for n+{sup 91}Zr, was studied at the A.W. Wright Nuclear Structure Laboratory at Yale. Particles were detected in the silicon telescope STARS (Silicon Telescope Array for Reaction Studies) and {gamma}-ray energies measured with germanium clover detectors from the YRAST (Yale Rochester Array for SpecTroscopy) ball. The experiment and preliminary observations will be discussed.

Directed assembly of discrete gold nanoparticle groupings usingbranched DNA scaffolds
The concept of self-assembled dendrimers is explored for the creation of discrete nanoparticle assemblies. Hybridization of branched DNA trimers and nanoparticle-DNA conjugates results in the synthesis of nanoparticle trimer and tetramer complexes. Multiple tetramer architectures are investigated, utilizing Au-DNA conjugates with varying secondary structural motifs. Hybridization products are analyzed by gel electrophoresis, and discrete bands are observed corresponding to structures with increasing numbers of hybridization events. Samples extracted from each band are analyzed by transmission electron microscopy, and statistics compiled from micrographs are used to compare assembly characteristics for each architecture. Asymmetric structures are also produced in which both 5 and 10 nm Au particles are assembled on branched scaffolds.
