Semi‐Analytical Models for Predicting the Maximum Longitudinal Flow Velocity in the Confluence Channel

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract In a channel confluence, different hydrodynamic characteristics can significantly affect the flow structure. As the main and tributary flow converges at the confluence, they are constrained by the recirculation zone, resulting in streamline contraction and an increase in flow velocity, thereby creating a zone of maximum velocity adjacent to ...

Direct Numerical Simulation of Solute Transport in Bioclogged Porous Media

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Biofilms in porous media significantly impact solute transport, beyond their role in reducing permeability through bioclogging. Experimental evidence has shown that biofilms can induce anomalous transport behaviors such as increased dispersion and pronounced tailing.

CEO Stress, Aging, and Death

The Journal of Finance, Volume 80, Issue 6, Page 3401-3442, December 2025.
ABSTRACT We assess the long‐term effects of managerial stress on aging and mortality. Using a difference‐in‐differences design, we apply neural network–based machine‐learning techniques to CEOs' facial images and show that exposure to industry distress shocks during the Great Recession produces visible signs of aging. We estimate a one‐year increase in

Fractional Q$Q$‐curvature on the sphere and optimal partitions

Journal of the London Mathematical Society, Volume 112, Issue 6, December 2025.
Abstract We study an optimal partition problem on the sphere, where the cost functional is associated with the fractional Q$Q$‐curvature in terms of the conformal fractional Laplacian on the sphere. By leveraging symmetries, we prove the existence of a symmetric minimal partition through a variational approach. A key ingredient in our analysis is a new
