Genetic Testing by Cancer Site
The Cancer Journal, 2012Women in the United States have a 12% lifetime risk of developing breast cancer. Although only about 5% to 10% of all cases of breast cancer are attributable to a highly penetrant cancer predisposition gene, individuals who carry a mutation in one of these genes have a significantly higher risk of developing breast cancer, as well as other cancers ...

To evaluate possible sites for NRAO's proposed Millimeter Array, we constructed interferometers to directly measure the tropospheric phase stability. These instruments observe an unmodulated 11.5 GHz beacon broadcast from a geostationary satellite and measure the phase difference between the signals received by two antennas 300 m apart.

CHI '01 extended abstracts on Human factors in computer systems - CHI '01, 2001
We observed the same task executed by 49 users on four production web sites. We tracked the rates of discovery of new usability problems on each site and, using that data, estimated the total number of usability problems on each site and the number of tests we would need to discover every problem. Our findings differ sharply from rules-of-thumb derived

“Rocket Testing Sites” presents some of the lesser known rocket testing sites founded with a better understanding of physics and rocketry provided by Goddard, beginning with the development of the V-2 and A-4 rockets. The chapter focuses on some histories of rocket testing involving Operation Paperclip and Werner Von Braun, such as the Saturn V and ...

Distance to Public Test Sites and HIV Testing
Medical Care Research and Review, 2007This article examines how proximity to the nearest publicly funded test site affects HIV testing. Using a sample of 5,361 Los Angeles County adults, multinomial logit models estimated simultaneously the likelihood of (1) obtaining an HIV test in the prior 2 years, and (2) testing in a private physician's office, a publicly funded medical clinic, or in

Existing systems are a larger opportunity for energy savings, through use of LCC methods, than new systems, for two reasons: There are 20 times as many pumps systems in the installed base as are purchased each year More existing systems have pumps or controls that are less than optimum since the pumping task can change over time.
