Automatic segmentation of histological structures in mammary gland tissue sections
Real-time three-dimensional (3D) reconstruction of epithelial structures in human mammary gland tissue blocks mapped with selected markers would be an extremely helpful tool for breast cancer diagnosis and treatment planning. Besides its clear clinical application, this tool could also shed a great deal of light on the molecular basis of breast cancer initiation and progression. In this paper we present a framework for real-time segmentation of epithelial structures in two-dimensional (2D) images of sections of normal and neoplastic mammary gland tissue blocks. Complete 3D rendering of the tissue can then be done by surface rendering of the structures detected in consecutive sections of the blocks. Paraffin embedded or frozen tissue blocks are first sliced, and sections are stained with Hematoxylin and Eosin. The sections are then imaged using conventional bright field microscopy and their background is corrected using a phantom image. We then use the Fast-Marching algorithm to roughly extract the contours of the different morphological structures in the images. The result is then refined with the Level-Set method which converges to an accurate (sub-pixel) solution for the segmentation problem. Finally, our system stacks together the 2D results obtained in order to reconstruct a 3D representation of the entire tissue …

Bundling Residential Telephone, Internet, and Video Services: Issues for Congress
This report discusses bundling and public policy issues for Congress. The federal Universal Service Fund - the federal subsidy program that assures affordable telephone rates for high-cost (rural) and low-income telephone customers as well as for schools, libraries, and rural health facilities - is supported by an assessment on interstate telecommunications revenues only. But it is difficult to identify the portion of revenues generated by a bundled service offering attributable to the interstate telecommunications portion of that bundle.

The Conservation Security Program in the 2002 Farm Bill
The Conservation Security Program (CSP), a new program enacted in section 2001 of the 2002 farm bill (P.L. 107-171) and administered by the Natural Resources Conservation Service, creates a three-tiered system rewarding increased levels of conservation on agricultural operations with increased payments. Payments include a base payment for acreage enrolled, a payment for new or existing conservation practices, and an “enhancement” payment for conservation exceeding minimum program standards.

Direct Numerical Simulation of Disperse Multiphase High-Speed Flows
A recently introduced Level-Set-based Cartesian Grid (LSCG) Characteristics-Based Matching (CBM) method is applied for direct numerical simulation of shock-induced dispersal of solid material. The method incorporates the latest advancements in the level set technology and characteristics-based numerical methods for solution of hyperbolic conservation laws and boundary treatment. The LSCG/CBM provides unique capabilities to simulate complex fluid-solid (particulate) multiphase flows under high-speed flow conditions and taking into account particle-particle elastic and viscoelastic collisions. The particular emphasis of the present study is placed on importance of appropriate modeling of particle-particle collisions, which are demonstrated to crucially influence the global behavior of high-speed multiphase particulate flows. The results of computations reveal the richness and complexity of flow structures in compressible disperse systems, due to dynamic formation of shocks and contact discontinuities, which provide an additional long-range interaction mechanism in dispersed high-speed multiphase flows.

Direct Observations of Austenite, Bainite and Martensite Formation During Arc Welding of 1045 Steel using Time Resolved X-Ray Diffraction
In-situ Time Resolved X-Ray Diffraction (TRXRD) experiments were performed during stationary gas tungsten arc (GTA) welding of AISI 1045 C-Mn steel. These synchrotron-based experiments tracked, in real time, phase transformations in the heat-affected zone of the weld under rapid heating and cooling conditions. The diffraction patterns were recorded at 100 ms intervals, and were later analyzed using diffraction peak profile analysis to determine the relative fraction of ferrite ({alpha}) and austenite ({gamma}) phases in each diffraction pattern. Lattice parameters and diffraction peak widths were also measured throughout the heating and cooling cycle of the weld, providing additional information about the phases that were formed. The experimental results were coupled with a thermofluid weld model to calculate the weld temperatures, allowing time-temperature transformation kinetics of the {alpha} {yields} {gamma} phase transformation to be evaluated. During heating, complete austenitization was observed in the heat affected zone of the weld and the kinetics of the {alpha} {yields} {gamma} phase transformation were modeled using a Johnson-Mehl-Avrami (JMA) approach. The results from the 1045 steel weld were compared to those of a 1005 low carbon steel from a previous study. Differences in austenitization rates of the two steels were attributed to differences in the base …

Electromagnetic Imaging of CO2 Sequestration at an Enhanced-Oil-Recovery Site
The two year LDRD-ER-089 project Electromagnetic Imaging of CO{sub 2} Sequestration at an Enhanced-Oil-Recovery Site used a dual track approach to imaging and interpreting the effectiveness and migration of CO2 injection at an enhanced oil recovery site. Both field data and laboratory data were used together to aid in the interpretation and understanding of CO{sub 2} flow in a heavily fracture enhanced oil recovery site. In particular, project highlights include; {lg_bullet} The development of a low-noise digital field system to measure the EM induction response to CO{sub 2} in a variety of field conditions. Central to this system is a low-noise induction receiver antenna that can measure the low-energy response of the CO{sub 2}. This system has consistently measured a shallow pseudo-miscible CO{sub 2} flood at source frequencies between 2.0 kHz and 10 kHz. In addition, the existing and added oil and brine in the formation have also been characterized. {lg_bullet} Comparisons of cross-well images with induction logs acquired before drilling suggest the EM induction resolution for CO2 imaging is equivalent with applications to waterflood imaging completed at LLNL. {lg_bullet} The development and use of laboratory equipment to conduct fluid and gas time-lapsed injection studies of core samples using fluids …

Enhancement of Strength and Ductility in Bulk Nanocrystalline Metals
The purpose of this project is to develop a robust scientific and technological framework for the design of high-strength and -ductility nanocrystalline materials for applications of technical importance to the Laboratory. The project couples theory and experiments with an emphasis on materials of macroscopic dimensions (mm to cm) that are composed of nanoscale (<100 nm) grains. There are four major tasks: (1) synthesize nanocrystalline materials with grain size in the 5- to 100-nm range; (2) conduct experimental studies to probe mechanisms of mechanical deformation and failure; (3) use large-scale simulation modeling technologies to provide insight to deformation mechanisms that may not be observable experimentally; and (4) check the results obtained from modeling, comparing experimental observations with results obtained from atomistic and dislocation-based simulations. This project supports efforts within the Stockpile Stewardship Program (SSP) to understand and predict properties of metals such as strength and ductility.

Hybrid Monte Carlo-Deterministic Methods for Nuclear Reactor-Related Criticality Calculations
The overall goal of this project is to develop, implement, and test new Hybrid Monte Carlo-deterministic (or simply Hybrid) methods for the more efficient and more accurate calculation of nuclear engineering criticality problems. These new methods will make use of two (philosophically and practically) very different techniques - the Monte Carlo technique, and the deterministic technique - which have been developed completely independently during the past 50 years. The concept of this proposal is to merge these two approaches and develop fundamentally new computational techniques that enhance the strengths of the individual Monte Carlo and deterministic approaches, while minimizing their weaknesses.
