Wildlife Biology, EarlyView.Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our

Gepta‐EX: a multi‐channel germanium detector for X‐ray absorption fine structure
Journal of Synchrotron Radiation, EarlyView.Gepta‐EX is a compact seven‐channel high‐purity germanium detector designed to deliver high‐resolution fluorescence X‐ray absorption fine‐structure measurements at photon energies where silicon detectors become effectively transparent. It provides excellent energy resolution across a broad energy range, avoids silicon escape‐peak artifacts, and offers ...

Reforming Export Control Regimes: Addressing Emerging Technologies Through Responsible Innovation
Global Policy, EarlyView.ABSTRACT The proliferation of dual‐use emerging technologies—such as artificial intelligence (AI), quantum computing, and additive manufacturing—poses a growing challenge for multilateral export control regimes. Designed for tangible goods and slower innovation cycles, existing arrangements increasingly struggle to govern technologies that are ...

The variance of the Stirling cycle numbers
, 2005 We show that the probability that two permutations of $n$ letters have the same number of cycles is \[\sim \frac{1}{2\sqrt{π\log{n}}}.\]
