Many DNA binding proteins are known to regulate gene expression. When that binding is altered, a disease state can result. A common method for measuring DNA binding, namely electrophoretic mobility shift assay (EMSA) is often used but it is not amenable to rapid screening of many samples. As an alternative method, we have developed a DNA binding assay for the tumor suppressor protein p53 in a 9...

AMIGA (Auger Muons and Infill for the Ground Array) is an upgrade of the Pierre Auger Observatory designed to extend its energy range of detection and to directly measure the muon content of the cosmic ray primary particle showers. The array will be formed by an infill of surface water-Cherenkov detectors associated with buried scintillation counters employed for muon counting. Each counter is ...

An essential component of the ionosphere is a small-scale electron density structure that causes scintillation of radio waves on transionospheric links. We briefly review the morphology of irregularities and physical mechanisms of their formation. Results of the scintillation theory relating statistical characteristics of irregularities and scintillation are also outlined. Examples of the scint...

Scintillation is a transmission impairment. The Received Satellite signals degradation due to the scintillation on space to earth link in tropical region. This proposed work goal is to find the performance evaluation of scintillation in clear sky conditions. To estimate and compare the statistic of atmospheric scintillation based on the parameters in ITUR model. To evaluate Atmospheric Amplitud...

As the millennium approaches we are faced with a period of increasing solar flux and intense ionospheric scintillation. Not only single-frequency, but also dualfrequency GPS measurements will be badly affected by deep scintillation, due to its temporal and spatial decorrelation characteristics. Using the scintillation observables derived from dual-frequency phase and signal-to-noise ratio measu...
