Power Dependent Study of CDSE-ZNS Quantum Dot Relaxation Dynamics by 2D Muppets
… dynamics are multiexponential and have a strong power dependence. Because single exciton and biexciton populations, are indistinguishable by any-dimensional experiments, there is uncertainty as to whether this power dependence comes from a biexciton or a photo-induced byproduct. Multiple …

The Availability of Interest Arbitration and Police Employment Outcomes
… of arbitration as a result of tactical action. A power-dependence based framework is used to test three propositions regarding interest arbitration: (1) passage of an arbitration law is partially determined by power relationships between unions and cities in a state; (2) once factors influencing …

Verification of d-wave pairing symmetry by microwave intermodulation distortion measurements in yttrium barium copper oxide
We report measurements of the temperature and power dependence of the microwave frequency intermodulation distortion (IMD) in high quality pulsed laser deposition (PLD) Yttrium Barium Copper Oxide (YBCO) on LaAlO3 substrate. A low-temperature (T < 30 K) increase in IMD is the observation of an …

Study of nonlinear microwave properties of high-temperature superconducting film
… process contributes to neither the low-power surface resistance nor the power dependence of the surface resistance. To understand the grain-boundary contributions to the nonlinear microwave properties, we introduced a coupled-grain RSJ series-array model which simulates an HTS film as a …
