HslVU is a two-component ATP-dependent protease, consisting of HslV peptidase and HslU ATPase. CodW and CodX, encoded by the cod operon in Bacillus subtilis, display 52% identity in their amino acid sequences to HslV and HslU in Escherichia coli, respectively. Here we show that CodW and CodX can function together as a new type of two-component ATP-dependent(More)
The Jet Propulsion Laboratory (JPL) and Ames Research Center (ARC) are partnering in the CubeSat Hydrometric Atmospheric Radiometer Mission (CHARM), a water vapor radiometer integrated on a 3U CubeSat platform, selected for implementation under NASA Hands-On Project Experience (HOPE-3). CHARM will measure 4 channels at 183 GHz water vapor line, subsets of(More)
Hepatocellular carcinoma (HCC) is a common malignancy worldwide and highly associated with chronic virus-B or -C infection and cirrhosis. Molecular studies have shown high frequency of loss of heterozygosity (LOH) in some specific chromosome regions, but LOH on chromosome 9 in HCC has not been thoroughly investigated. In our investigation of chromosome 9(More)
The tumor suppressor gene p16 (CDKN2/MTS-1/INK4A) is an important component of the cell cycle and inactivation of the gene has been found in a variety of human cancers. In order to investigate the role of p16 gene in the tumorigenesis of hepatocellular carcinoma (HCC), 48 cases of HCC were analysed for p16 alterations by: methylation-specific PCR (MSP) to(More)
An L-band total power receiver for use in a synthetic thinned array radiometer (STAR) is described. The total power architecture of a radiometer receiver requires special considerations to control gain fluctuations due to small temperature drifts. The STAR application requires consistent passband and stable phase between receivers. The design presented(More)

Small satellites are now, more than ever, being utilized as viable space craft to perform measurements for the science and commercial sector. Shrinking budgets have placed an emphasis on low cost missions, and the technology is now available for these small mass and volume platforms. Specifically, the cost of accessing space continues to fall, with(More)
The Jet Propulsion Laboratory has developed a new airborne sensor, the Microwave Temperature and Humidity Profiler (MTHP), by adding a 183 GHz receiver to the current Microwave Temperature Profiler (MTP). The instrument scans ahead of the aircraft flight path sampling at multiple angles, allowing for atmospheric retrievals above and below the aircraft, to(More)
