Inhibition of heregulin expression blocks tumorigenicity and metastasis of breast cancer
The growth factor Heregulin (HRG) is expressed in 30% of breast cancer tumors. HRG induces tumorigenicity and metastasis of breast cancer cells. Our investigation into whether blockage of HRG reduces the aggressiveness of breast cancer cells demonstrated that transfection of MDA-MB-231 with an HRG antisense cDNA suppressed proliferation, tumorigenicity, and metastasis. Blockage of the aggressive phenotype is mediated possibly through inactivation of the erbB signaling pathways and a decrease in MMP-9 activity. Our study is the first to report that HRG is a key promoter of breast cancer progression and should be deemed as a potential target in developing therapies for the treatment of breast carcinomas.

Inspectors General: Department of Defense IG Peer Reviews
Correspondence issued by the General Accounting Office with an abstract that begins "The 1997 peer review of the Department of Defense (DOD) Inspector General (IG) done by the Environmental Protection Agency IG resulted in a qualified opinion. The peer review report questioned the quality assurance system used by the DOD IG and said that the reviewed audits did not fully comply with Government Auditing Standards. The 2000 peer review done by the Department of the Treasury IG for Tax Administration (TIGTA) also resulted in a unqualified opinion. Although TIGTA cited several problems, the peer review report concluded that the quality assurance system used by the DOD IG reasonably ensured compliance with auditing standards. However, after the peer review had been completed, a letter was sent to Congress, the press, and others questioning the integrity of the documentation that the DOD IG provided to the TIGTA peer review staff. A DOD IG internal investigation later confirmed that the work papers for one of the audits chosen for peer review had been altered and destroyed. The report concluded that these actions violated Government Auditing Standards, internal DOD IG audit policies, and the expectations of the external peer review staff. TIGTA then withdrew …

Multi-Scale Thermohydrologic Model Sensitivity-Study Calculations in Support of the SSPA
The purpose of this calculation report is to document the thermohydrologic (TH) model calculations performed for the Supplemental Science and Performance Analysis (SSPA), Volume 1, Section 5 and Volume 2 (BSC 2001d [DIRS 155950], BSC 2001e [DIRS 154659]). The calculations are documented here in accordance with AP-3.12Q REV0 ICN4 [DIRS 154418]. The Technical Working Plan (Twp) for this document is TWP-NGRM-MD-000015 Real. These TH calculations were primarily conducted using three model types: (1) the Multiscale Thermohydrologic (MSTH) model, (2) the line-averaged-heat-source, drift-scale thermohydrologic (LDTH) model, and (3) the discrete-heat-source, drift-scale thermal (DDT) model. These TH-model calculations were conducted to improve the implementation of the scientific conceptual model, quantify previously unquantified uncertainties, and evaluate how a lower-temperature operating mode (LTOM) would affect the in-drift TH environment. Simulations for the higher-temperature operating mode (HTOM), which is similar to the base case analyzed for the Total System Performance Assessment for the Site Recommendation (TSPA-SR) (CRWMS M&O 2000j [DIRS 153246]), were also conducted for comparison with the LTOM. This Calculation Report describes (1) the improvements to the MSTH model that were implemented to reduce model uncertainty and to facilitate model validation, and (2) the sensitivity analyses conducted to better understand the influence of parameter …

The National Museum of the Pacific War presents an oral interview with Manuel Garcia. Garcia was born in Goliad, Texas on 11 June 1920. He attended the Rincon Bend County School, a segregated school, until the seventh grade. In 1940, he joined the Army and underwent basic training at Fort Sam Houston, Texas. He was then assigned to the 2nd Infantry Division, 38th Infantry Regiment. The division moved to Camp McCoy, Wisconsin. In 1943 the division went to Camp Shanks, New York where they boarded a ship bound for Ireland. After ten months of intensive training the division participated in Operation Overlord, landing on Omaha Beach on June 7 1944. Garcia describes leaving the transport ship to land on the beach and seeing wreckage and bodies stacked like wood. He was slightly wounded and went to a field hospital for treatment. Several days later he was severely wounded by German artillery fire. After being taken to another field hospital, he was placed aboard a Piper Cub and flown to the Army hospital in Cheltenham, England where surgeons amputated one of his legs. Garcia returned to the United States by a hospital ship and was placed in several military hospitals until …

PDE-based Non-Linear Diffusion Techniques for Denoising Scientific and Industrial Images: An Empirical Study
Removing noise from data is often the first step in data analysis. Denoising techniques should not only reduce the noise, but do so without blurring or changing the location of the edges. Many approaches have been proposed to accomplish this; in this paper, they focus on one such approach, namely the use of non-linear diffusion operators. This approach has been studied extensively from a theoretical viewpoint ever since the 1987 work of Perona and Malik showed that non-linear filters outperformed the more traditional linear Canny edge detector. They complement this theoretical work by investigating the performance of several isotropic diffusion operators on test images from scientific domains. They explore the effects of various parameters such as the choice of diffusivity function, explicit and implicit methods for the discretization of the PDE, and approaches for the spatial discretization of the non-linear operator etc. They also compare these schemes with simple spatial filters and the more complex wavelet-based shrinkage techniques. The empirical results show that, with an appropriate choice of parameters, diffusion-based schemes can be as effective as competitive techniques.

Polarization Studies in Fast-Ion Beam Spectroscopy
In a historical review, the observations and the insight gained from polarization studies of fast ions interacting with solid targets are presented. These began with J. Macek's recognition of zero-field quantum beats in beam-foil spectroscopy as indicating alignment, and D.G. Ellis' density operator analysis that suggested the observability of orientation when using tilted foils. Lastly H. Winter's studies of the ion-beam surface interaction at grazing incidence yielded the means to produce a high degree of nuclear orientation in ion beams.

Proton radiation damage in high-resistivity n-type silicon CCDs
A new type of p-channel CCD constructed on high-resistivity n-type silicon was exposed to 12 MeV protons at doses up to 1x1011 protons/cm2. The charge transfer efficiency was measured as a function of radiation dose and temperature. We previously reported that these CCDs are significantly more tolerant to radiation damage than conventional n-channel devices. In the work reported here, we used pocket pumping techniques and charge transfer efficiency measurements to determine the identity and concentrations of radiation induced traps present in the damaged devices.
