Long-term slip rate of the southern San Andreas Fault, from 10Be-26Al surface exposure dating of an offset alluvial fan
We determine the long-term slip rate of the southern San Andreas Fault in the southeastern Indio Hills using {sup 10}Be and {sup 26}Al isotopes to date an offset alluvial fan surface. Field mapping complemented with topographic data, air photos and satellite images allow to precisely determine piercing points across the fault zone that are used to measure an offset of 565 {+-} 80 m. A total of twenty-six quartz-rich cobbles from three different fan surfaces were collected and dated. The tight cluster of nuclide concentrations from 19 samples out of 20 from the offset fan surface implies a simple exposure history, negligible prior exposure and erosion, and yield an age of 35.5 {+-} 2.5 ka. The long-term slip rate of the San Andreas Fault south of Biskra Palms is thus 15.9 {+-} 3.4 mm/yr. This rate is about 10 mm/yr slower than geological (0-14 ka) and short-term geodetic estimates for this part of the San Andreas Fault implying changes in slip rate or in faulting behavior. This result puts new constraints on the slip rate of the San Jacinto and on the Eastern California Shear Zone for the last 35 ka. Our study shows that more sites along the major …

Modeling Reluctance-Assisted PM Motors
This report contains a derivation of the fundamental equations used to calculate the base speed, torque delivery, and power output of a reluctance-assisted PM motor which has a saliency ratio greater than 1 as a function of its terminal voltage, current, voltage-phase angle, and current-phase angle. The equations are applied to model Motor X using symbolically-oriented methods with the computer tool Mathematica to determine: (1) the values of current-phase angle and voltage-phase angle that are uniquely determined once a base speed has been selected; (2) the attainable current in the voltage-limited region above base speed as a function of terminal voltage, speed, and current-phase angle; (3) the attainable current in the voltage-limited region above base speed as a function of terminal voltage, speed, and voltage-phase angle; (4) the maximum-power output in the voltage-limited region above base speed as a function of speed; (5) the optimal voltage-phase angle in the voltage-limited region above base speed required to obtain maximum-power output; (6) the maximum-power speed curve which was linear from rest to base speed in the current limited region below base speed; (7) the current angle as a function of saliency ratio in the current-limited region below base speed; and (8) the …

The Autonomous Pathogen Detection System
We developed, tested, and now operate a civilian biological defense capability that continuously monitors the air for biological threat agents. The Autonomous Pathogen Detection System (APDS) collects, prepares, reads, analyzes, and reports results of multiplexed immunoassays and multiplexed PCR assays using Luminex{copyright} xMAP technology and flow cytometer. The mission we conduct is particularly demanding: continuous monitoring, multiple threat agents, high sensitivity, challenging environments, and ultimately extremely low false positive rates. Here, we introduce the mission requirements and metrics, show the system engineering and analysis framework, and describe the progress to date including early development and current status.

A hydrologic view on Biot's theory of poroelasticity
The main objective of this work is to obtain a simplified asymptotic representation of the reflection of seismic signal from a fluid-saturated porous medium in the low-frequency domain. In the first part, we derive the equations of low-frequency harmonic waves in a fluid-saturated elastic porous medium from the basic concepts of filtration theory. We demonstrate that the obtained equations can be related to the poroelasticity model of Frenkel-Gassmann-Biot, and to pressure diffusion model routinely used in well test analysis as well. We thus try to put the poroelastic and filtration theories on the same ground. We study the reflection of a low-frequency signal from a plane interface between elastic and elastic fluid-saturated porous media. We obtain an asymptotic scaling of the frequency-dependent component of the reflection coefficient with respect to a dimensionless parameter depending on the frequency of the signal and the reservoir fluid mobility. We also investigate the impact of the relaxation time and tortuosity on this scaling.

Interbasin Flux Measurements Using Simple Methods
The Vertical Transport and Mixing (VTMX) campaign, sponsored by the US Department of Energy, took place in the Salt Lake Valley during October, 2000. The purpose of VTMX was to further understanding of meteorological processes that govern vertical transport and mixing in complex terrain, particularly during nocturnal stable periods and their morning and evening transition periods. These meteorological processes were the subject of numerous sponsored studies during VTMX. The Salt Lake (Salt Lake City) Basin and the Utah Basin to its south are separated by the Traverse Range. Near-surface airflow between the basins is channeled through the Jordan Narrows, also the channel for the Jordan River that flows from the Utah Basin into Salt Lake via the Salt Lake Basin. Jordan Narrows is thus a potentially significant corridor for pollutant transport between the two basins. This paper describes simple and direct pollutant (PM{sub 10}) measurements, with concurrent continuous meteorological monitoring, to characterize pollutant transport between the two basins via low-level stable nocturnal drainage flow, with an emphasis on its vertical variability when mixing is limited. The Jordan Narrows has similarities to other transport corridors where direct in-corridor monitoring of pollutant flux might enhance pollution forecasts during transport conditions. Thus their …

MUSE-4 experiment measurements and analysis.
This report presents a review of the activities performed by the five teams involved in the MUSE-4 experimental program. More details are provided on the contribution by ANL during the year 9/02 to 9/03. The ANL activity consisted both in direct participation in the experimental measurements and in the physics analysis of the experimental data, mainly for the reactivity level, adjoint flux and fission rate distributions and the analysis of dynamic measurements for reactivity determination techniques in subcritical systems. The results provided to complete the Benchmark organized by the OECD and the CEA on the experiment MUSE-4 are also presented. Deterministic calculations have been performed via the ERANOS code system in connection with JEF2.2, ENDF/B-V and ENDF/B-VI data files.

A Mining/Contained Explosion Source Phenomenology Experiment to Improve Nuclear Test Monitoring
We propose an experiment to investigate the similarities and differences in source phenomenology and regional seismic discriminant behavior between normal production mining explosions and fully contained nuclear tests. The experiment would consist of a minimum of two large, nearly co-located explosions, which would be recorded at regional distances: (1) a normal delay fired production mining explosion, and (2) a single chemical explosion contained and buried at underground nuclear test depth.
