Two-Color interferometry as a fluctuation diagnostic on Alcator C-Mod
The two-color interferometer diagnostic on Alcator C-Mod has been upgraded to measure line-integrated electron density fluctuations for turbulence and transport studies. Heterodyne signals from ten vertical-viewing CO2 laser chords are demodulated relative to a local oscillator using high bandwidth …

Theoretical and Experimental Analysis of the Performance of Two-Color Laser Ranging Systems
… from the ground to an orbiting satellite. Two-color laser ranging systems can be used to determine the atmospheric delay by measuring the difference in propagation times between optical pulses transmitted at the two different wavelengths. The differential propagation time can also be used …

Two-Color Fluorescent Analysis of Connexin 36 Turnover and Trafficking – Relationship to Functional Plasticity
<p>Gap junctions (GJ) formed of Cx36 show tremendous functional plasticity on several time scales. Changes in connexin phosphorylation modify coupling in minutes through an order of magnitude, but recent studies also imply involvement of connexin turnover in regulating cell-cell communication. We …

Characterization of a two-color magneto-optical trap for a spin-squeezed optical lattice clock
… that simultaneously scatters light from two atomic transitions, in order to reduce the minimum magnetic field gradient required for trapping atoms. From the experimental data, we propose a model of the MOT where one transition is responsible for trapping the atoms the other transition is …

A two-color bacterial two-hybrid system for selecting sequence-specific DNA-binding proteins via fluorescence activated cell sorting
… system (starting with a pre-existing bacterial two-hybrid selection system) which allows the selection of proteins based on their preference of one DNA site over another. I use this system to attempt to attenuate the affinity of a zinc finger protein without destroying its specificity. Finally, …

Part 1: Isolation of Orexin Receptor Regulators via a Microarray-Based,Two-Color Cell Binding Screen. Part II: Targeted Inactivation of Proteins triggered by Visible Light.
… receptor regulators via a microarray-based, two-color, cell-binding screen. We have developed a novel two-color, cell-binding peptoid microarray screening approach with which we discovered new orexin receptor ligands. We found that peptoids on microarray, which showed preferential binding to …
