Verification of Gyrokinetic (delta)f Simulations of Electron Temperature Gradient Turbulence
The GEM gyrokinetic {delta}f simulation code [Chen, 2003] [Chen, 2007] is shown to reproduce electron temperature gradient turbulence at the benchmark operating point established in previous work [Nevins, 2006]. The electron thermal transport is within 10% of the expected value, while the turbulent fluctuation spectrum is shown to have the expected intensity and two-point correlation function.

VVER-1000 weapons-grade MOX computational benchmark analysis
Calculations of computational benchmark problems for the disposition of weapons-grade plutonium fuel in VVER-1000 reactors have been performed under the Joint US/Russian Fissile Material Disposition Program. The benchmarks cover pin cell, single fuel assembly, and multi-assembly structures with several different fuel types, moderator densities, and boron content for operational and off-normal conditions. Fuel depletion is performed to a burnup of 60 MWd/kgHM. The results of the analysis of the benchmarks with US and Russian code systems have been compared and indicated good agreement among the different methods and data.

Wagon Brake.
Patent for a new and improved wagon-brake. This design consists "of a suitable support which is attached to the rear axle-tree, the brake which is pivoted to this support, the connecting-rod pivoted to the brake, and the operating lever pivoted upon a supporting bar which extends from one standard to the other . . . The object of [the] invention is to produce a wagon-brake which is simple in construction, effective in operation, and by means of which the driver can instantly apply the brake with great power" (lines 14-25).

Weapons of Mass Destruction: Trade Between North Korea and Pakistan
In October 2002, the United States confronted North Korea about its alleged clandestine uranium enrichment program. Soon after, the Agreed Framework collapsed, North Korea expelled international inspectors, and withdrew from the Nuclear Nonproliferation Treaty (NPT). U.S. intelligence officials claimed Pakistan was a key supplier of uranium enrichment technology to North Korea, and some media reports suggested that Pakistan had exchanged centrifuge enrichment technology for North Korean help in developing longer range missiles.

Web document clustering using hyperlink structures
With the exponential growth of information on the World Wide Web there is great demand for developing efficient and effective methods for organizing and retrieving the information available. Document clustering plays an important role in information retrieval and taxonomy management for the World Wide Web and remains an interesting and challenging problem in the field of web computing. In this paper we consider document clustering methods exploring textual information hyperlink structure and co-citation relations. In particular we apply the normalized cut clustering method developed in computer vision to the task of hyperdocument clustering. We also explore some theoretical connections of the normalized-cut method to K-means method. We then experiment with normalized-cut method in the context of clustering query result sets for web search engines.

Wildfire Funding
This report briefly describes the three categories of federal programs for wildfire protection. One is to protect the federal lands managed by the U.S. Department of Agriculture, Forest Service (FS), and by the U.S. Department of the Interior, whose wildfire programs are coordinated by the Bureau of Land Management (BLM). A second category assists state and local governments and communities in protecting nonfederal lands; these programs are used to reduce wildland fuels, to otherwise prepare for fire control, to contain and control wildfires, and to respond after severe wildfires have burned. A third category of federal programs supports fire research, fire facilities, and improvements in forest health. The last section of this report discusses the impact of high and rising wildfire costs.

Wire-rope emplacement of diagnostics systems
The study reported here was initiated to determine if, with the Cable Downhole System (CDS) currently under development, there is an advantage to using continuous wire rope to lower the emplacement package to the bottom of the hole. A baseline design using two wire ropes as well as several alternatives are discussed in this report. It was concluded that the advantages of the wire-rope emplacement system do not justify the cost of converting to such a system, especially for LLNL's maximum emplacement package weights.

The Zeta Potential of Surface-Functionalized Metallic Nanorod Particles in Aqueous Solution
Metallic nanoparticles suspended in aqueous solutions, and functionalized with chemical and biological surface coatings, are important elements in basic and applied nanoscience research. Many applications require an understanding of the electrokinetic or colloidal properties of such particles. In this paper we describe the results of experiments to measure the zeta potential of metallic nanorod particles in aqueous saline solutions, including the effects of pH, ionic strength, metallic composition, and surface functionalization state. Particle substrates tested include gold, silver, and palladium monometallic particles as well as gold/silver bimetallic particles. Surface functionalization conditions included 11-mercaptoundecanoic acid (MUA), mercaptoethanol (ME), and mercaptoethanesulfonic acid (MESA) self-assembled monolayers (SAMs), as well as MUA layers subsequently derivatized with proteins. Zeta potential data for typical charge-stabilized polystyrene particles are also presented for comparison. Experimental data are compared with theory. The results of these studies are useful in predicting and controlling the aggregation, adhesion, and transport of functionalized metallic nanoparticles within microfluidic devices and other systems.
