Phase Transition in strongly-correlated VO2: Time-domainAssignment of Cause and Effect
We establish time-domain hierarchy between structural andelectronic effects in the strongly correlated system VO2. Theinsulator-to-metal transition is driven directly by structural changerather than by electron-electron correlations.

Grant No DE-FG02-03ER83720 Report for US Department of Engery
Effective and reliable nuclear monitoring requires discrimination between small magnitude explosions and earthquakes based on the use of limited regional data. Lg is generally the largest seismic phase from both explosion and earthquake sources recorded at regional distances. For small events, Lg may sometimes be the only well-recorded seismic phase so that discriminants based only on the use of Lg are especially desirable. Recent research has provided significantly better understanding of Lg by demonstrating that the explosion-generated Rg makes significant contribution to the low-frequency S or Lg from explosions. Near-source scattering of explosion-generated Rg appears to be a viable mechanism for generating low-frequency(< 2 Hz) Lg waves from explosions. Detailed knowledge of the complex scattering process is, however, still incomplete and is in fact the subject of several ongoing studies. Our analysis of regional data from nuclear explosions from both Nevada Test Site (NTS) and Kazakh Test Site (KTS) and nearby earthquakes in Phase I has suggested that there are several reliable source discrimination methods only based on the use of Lg at regional distances. These discriminants should be. especially useful for small magnitude seismic events for which Lg may be the only well-recorded seismic phase. Our results suggest four …

Analytical Tests for Ray Effect Errors in Discrete Ordinate Methods for Solving the Neutron Transport Equation
This paper contains three analytical solutions of transport problems which can be used to test ray-effect errors in the numerical solutions of the Boltzmann Transport Equation (BTE). We derived the first two solutions and the third was shown to us by M. Prasad. Since this paper is intended to be an internal LLNL report, no attempt was made to find the original derivations of the solutions in the literature in order to cite the authors for their work.

Proof-of-Concept Demonstration Results for Robotic Visual Servo Controllers
There is significant motivation to provide robotic systems with improved autonomy as a means to significantly accelerate deactivation and decommissioning operations while also reducing the associated costs, removing human operators from hazardous environments, and reducing the required burden and skill of human operators. To achieve improved autonomy, fundamental research is focused on the challenges of developing visual servo controllers. The challenge in developing these controllers is that a camera provides 2-dimensional image information about the 3-dimensional Euclidean-space through a perspective (range dependent) projection that can be corrupted by uncertainty in the camera calibration matrix. Disturbances in this relationship (i.e., corruption in the sensor information) propagate erroneous information to the feedback controller of the robot, leading to potentially unpredictable task execution. This technical manual describes 3 proof-of-concept demonstrations of visual servo controllers developed from fundamental research aimed at these challenges. Specifically, one section describes the implementation of a cooperative visual servo control scheme with a camera-in-hand and a fixed camera to track a moving target despite uncertainty in the camera calibration and the unknown constant distance from the camera to a target where the camera is mounted on the end-effector of a 6 degrees-of-freedom hydraulic robot manipulator. The next section describes …

Supersonic Propagation of Ionization Waves in an Under-Dense, Laser-Produced Plasma
We observe a laser-driven supersonic ionization wave heating a mm-scale plasma of sub-critical density up to 2-3 keV electron temperatures. Propagation velocities initially 10 times the sound speed were measured by means of time-resolved x-ray imaging diagnostics. The measured ionization wave trajectory is modeled analytically and by a 2D radiation-hydrodynamics code. The comparison to the modeling suggests that nonlocal heat transport effects may contribute to the attenuation of the heat wave propagation.

Africa: Development Issues and Policy Options
This report details and analyzes U.S. foreign aid to Africa, particularly in the Sub-Saharan region. Moreover, the report tends to focus on the overall lack of development even though Africa has been getting the aid. The debate hinges on whether or not development is in African control, citing issues such as the HIV/AIDS pandemic and corrupt governments.
