A nanoscale sensor employing fluorescent resonance energy transfer interactions between fluorescent quantum dots (QDs) and organic quencher molecules can be used for the multiplexed detection of biological antigens in solution. Detection occurs when the antigens to be detected displace quencher-labelled inactivated (or dead) antigens of the same type(More)
This paper first proposes a method to estimate the altitude of an aircraft using two 2-D radars for Air Traffic Control (ATC) applications. Assuming that the aircraft flies with a nearly constant velocity and nearly constant height, we first estimate its velocity, initial position in 3-D coordinates from the measurements of two 2-D radars using a maximum(More)
Systematic theoretical investigations are carried out under the density functional formalism in an effort to understand the initial structural evolution due to the adsorption of ZnTe on As-exposed Si(211). Our calculations indicate that after the adsorption of Zn and Te on the As-exposed Si(211), the stable atomic structure qualitatively follows the ideal(More)
