Fundamental aspects of netted radar performance [PDF]
, 2010 Netted radar employs several spatially distributed transmitters and receivers for information retrieval. This system topology offers many advantages over traditional monostatic and bistatic systems which use a single transmitter and a single receiver ...

Physician Behavior in the Presence of a Secondary Market: The Case of Prescription Opioids
Econometrica, Volume 94, Issue 5, Page 1489-1528, September 2026.This paper examines how drug diversion influences the prescribing practices of physicians and the equilibrium health impacts of prescription medications. Focusing on the case of prescription opioids, a commonly prescribed and frequently diverted medication at the heart of the worst drug crisis in U.S. history, I design and estimate a model of physician

The Role of Lightning in Atmospheric Chemistry
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

On Intercept Estimation in the Sample Selection Model [PDF]
We provide a proof of the consistency and asymptotic normality of the estimator suggested by Heckman (1990) for the intercept of a semiparametrically estimated sample selection model.
