CONTROLLING ACTIVATED PROCESSES [PDF]

open access: yesFluctuation and Noise Letters, 2001
The rates of activated processes, such as escape from a metastable state and nucleation, are exponentially sensitive to an externally applied field. We describe how this applies to modulation by high-frequency fields and illustrate it with experimental observations.

Improved Observability in Distribution Grids Using Correlational Measurements

open access: yesIEEE Access, 2022
This paper develops a novel pseudo-measurement construct termed a Correlational Measurement (CM) to improve observability and state estimation accuracy. CMs utilize the correlation between similar classes of loads and DERs.
