Detector Description and Performance for the First Coincidence Observations between LIGO and GEO

For 17 days in August and September 2002, the LIGO and GEO interferometer gravitational wave detectors were operated in coincidence to produce their first data for scientific analysis. Although the detectors were still far from their design sensitivity levels, the data can be used to place better upper limits on the flux of gravitational waves incident on the earth than previous direct measurements. This paper describes the instruments and the data in some detail, as a companion to analysis papers based on the first data.Comment: 41 pages, 9 figures 17 Sept 03: author list amended, minor editorial change

Using in situ hybridisation to localize renal gene expression in tissue sections

The basics of in situ hybridization have been widely applied to a diverse range of situations where we need to localize the distribution of nucleic acids. Advances in other molecular techniques such as the advent of gene microarrays has not diminished th ISI Download 31/08/0
