We present a novel labeling technique for detection and speciation of organochloride compounds using microcapillary zone electrophoresis coupled with laser induced fluorescence detection. Organochloride compounds in an aqueous mixture are conjugated with glutathione using 1,5 Diazabicyclo [4.3.0] non-5-ene as a catalyst. The conjugated species are then labeled with Pacific Blue succinimidyl est...

To reduce sampling error as much as possible in the detection of prostate cancer, extensive transition zone sampling, in addition to the standard sextant random systematic biopsies, has been proposed. Improved biopsy techniques should make possible earlier and more effective detection of prostate cancer in a population where the incidence is low. Evaluation of such biopsies for elderly Japanese...

Proposed and demonstrated is a minimally invasive optical beam profiler using a non-pixelated liquid crystal spatial light modulator. The profiler features high detection sensitivity in the visible band, high 50 lines/mm spatial resolution, beam observation zone 100 % fill factor and magnification flexibility, and video rate operations. Applications for this beam profiler includes plug and test...

Wireless networks are exposed to many attacks which of one is spoofing attack. The networks performance will be affected more when the attackers are present. We propose to use the spatial correlation of received signal strength (RSS) inherited from wireless nodes to detect the spoofing attacks. K means clustering is used to determine the number of attackers. In this paper we proposed to use Enh...

Electrophoresis in microfluidic devices is becoming a useful analytical platform for a variety of biological assays. In this report, we present a method that allows for an increased sensitivity of detection of fluorescent molecules in microfluidic electrophoresis devices. This capability is provided by the implementation of a particular buffer system that is designed to initially function in an...
