Comparison of Four Parallel Algorithms For Domain Decomposed Implicit Monte Carlo
We consider two existing asynchronous parallel algorithms for Implicit Monte Carlo (IMC) thermal radiation transport on spatially decomposed meshes. The two algorithms are from the production codes KULL from Lawrence Livermore National Laboratory and Milagro from Los Alamos National Laboratory. Both algorithms were considered and analyzed in an implementation of the KULL IMC package in ALEGRA, a Sandia National Laboratory high energy density physics code. Improvements were made to both algorithms. The improved Milagro algorithm performed the best by scaling nearly perfectly out to 244 processors.

Comparison of Four Parallel Algorithms For Domain Decomposed Implicit Monte Carlo
Four different algorithms for domain decomposed Monte Carlo are outlined, and the performance of each is measured. These algorithms are implemented in the KULL IMC package [4] running inside of ALEGRA [1]. This package implements the Implicit Monte Carlo (IMC) scheme for thermal radiation transport of Fleck and Cummings [3].

ARE MAGNETIC MONOPOLES HADRONS?
The charges of magnetic monopoles are constrained to a multiple of 2{pi} times the inverse of the elementary unit electric charge. In the standard model, quarks have fractional charge, raising the question of whether the basic magnetic monopole unit is a multiple of 2{pi} or three times that. A simple lattice construction shows how a magnetic monopole of the lower strength is possible if it interacts with gluonic fields as well. Such a monopole is thus a hadron. This is consistent with the construction of magnetic monopoles in grand unified theories.

Oral History Interview with Gerard Roland Vela, July 21, 2004
Access:
Use of this item is restricted to the UNT Community
Interview with Dr. Gerard Roland Vela, UNT Professor Emeritus of Microbiology. The interview includes Vela's personal experiences about childhood and education, serving in World War II-era U.S. Navy, having a fellowship at Harvard University, and joining the North Texas faculty in 1965. Additionally, Vela discusses his family history, his love of chemistry, genetics, and microbiology, the growing pains involved with transitioning North Texas into a research university, the construction of a research program, his relationship with students, and his service on the Denton City Council. Photographs are included throughout the interview.

Final Report on ASU Research Funded through Lawrence Livermore National Laboratory Grant ASU XAJ9991/CO
The line of inquiry which the ASU lidar group has been investigating, with collaboration and support from LLNL, is to create approaches and algorithms for better utilizing the rich information available through modern remote sensors in dispersion modeling systems. In particular, our goal is to create a lidar-data-driven dispersion model mode in ADAPT/LODI. This report describes progress towards this goal during the 2002/2003 academic year. Because of the nature of lidar data and the necessity to utilize additional information, both numerical and measured, this is essentially a data retrieval and data fusion project. With the current generation of commercially available lidar, the scope of the domain in which we are interested is initially 4 to 14 kilometers in radius, where the potentially scanned domain is roughly hemispherical. Figure 1, for example, taken from a recent lidar deployment in Oklahoma City, shows visually the most typical range of the domain that can be probed with the ASU lidar. Ranges 2 or 3 times the distance to the cluster of buildings in the photograph can be probed with a properly functioning, commercially available lidar. This could be of significant value for protecting key buildings with roof-top located remote sensors coupled with dispersion …

Feature Subset Selection, Class Separability, and Genetic Algorithms
The performance of classification algorithms in machine learning is affected by the features used to describe the labeled examples presented to the inducers. Therefore, the problem of feature subset selection has received considerable attention. Genetic approaches to this problem usually follow the wrapper approach: treat the inducer as a black box that is used to evaluate candidate feature subsets. The evaluations might take a considerable time and the traditional approach might be unpractical for large data sets. This paper describes a hybrid of a simple genetic algorithm and a method based on class separability applied to the selection of feature subsets for classification problems. The proposed hybrid was compared against each of its components and two other feature selection wrappers that are used widely. The objective of this paper is to determine if the proposed hybrid presents advantages over the other methods in terms of accuracy or speed in this problem. The experiments used a Naive Bayes classifier and public-domain and artificial data sets. The experiments suggest that the hybrid usually finds compact feature subsets that give the most accurate results, while beating the execution time of the other wrappers.

GaAs Blocked-Impurity-Band Detectors for Far-Infrared Astronomy
High-purity and doped GaAs films have been grown by Liquid-phase epitaxy (LPE) for development of a blocked impurity band (BIB) detector for far-infrared radiation. The film growth process developed has resulted in the capability to grow GaAs with a net active impurity concentration below 1 x 10{sup 13} cm{sup -3}, ideal for the blocking layer of the BIB detector. The growth of n-type LPE GaAs films with donor concentrations below the metal-insulator transition, as required for the absorbing layer of a BIB detector, has been achieved. The control of the donor concentration, however, was found to be insufficient for detector production. The growth by LPE of a high-purity film onto a commercially grown vapor-phase epitaxial (VPE) n-type GaAs doped absorbing layer resulted in a BIB device that showed a significant reduction in the low-temperature dark current compared to the absorbing layer only. Extended optical response was not detected, most likely due to the high compensation of the commercially grown GaAs absorbing layer, which restricts the depletion width of the device.

An Evaluation of UDP Transport Protocols
Although the speed of LAN and WAN networking is growing at an exponential rate, the applications that use those networks have not followed suit. With fiber optic interconnects, gigahertz processor speeds, and 10 gigabit per second network interface cards, hardware does not seem to be the limiting factor. It is becoming increasingly obvious that the protocols that are the basis of networking today are ill-suited to a new generation of networking technology. For this reason, Oak Ridge National Laboratory is particularly interested in improving bulk transfers over high-bandwidth, high-latency networks because of its involvement in storage and in the transfer of data for cutting-edge scientific applications. This report summarizes our evaluation of a new group of protocols specifically designed to get more useful bandwidth from today's high speed, wide area networks.
