Convergence Time Towards Periodic Orbits in Discrete Dynamical Systems
, 2014 We investigate the convergence towards periodic orbits in discrete dynamical systems. We examine the probability that a randomly chosen point converges to a particular neighborhood of a periodic orbit in a fixed number of iterations, and we use ...

Earth's Future, Volume 14, Issue 5, May 2026.Abstract Facilitating decisions over future infrastructure transitions benefits from understanding past strategies to inform future scenario development. Here, we apply a scenario‐based indicator framework to generate plausible, spatially explicit future Public Water Supply Infrastructure (PWSI) alternatives.

Ergodicity and Mixing in Quantum Dynamics
, 2016 After a brief historical review of ergodicity and mixing in dynamics, particularly in quantum dynamics, we introduce definitions of quantum ergodicity and mixing using the structure of the system's energy levels and spacings.

Size‐based regulation and water quality: Evidence from the Iowa hog industry
American Journal of Agricultural Economics, Volume 108, Issue 3, Page 829-855, May 2026.Abstract The growing prevalence of animal feeding operations (AFOs) in the United States raises concerns among the public and regulators about their impact on local environmental quality. By linking historical regulatory records of AFOs in Iowa to downstream surface water pollution monitors, this paper studies the effects of the 2003 Clean Water Act ...
