Flow‐Dependent Inertial Permeability Defines Crossover Between Darcy and Forchheimer Flow Regimes

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We present mechanistic evidence that the Forchheimer inertial permeability coefficient (β $\beta $) is flow‐dependent in the weak‐to‐intermediate inertia crossover regime, governed by pore‐scale eddy growth‐to‐confinement dynamics. In contrast to classical theory, β $\beta $ attains steady‐state (βs ${\beta }_{s}$) asymptotically in the ...

Spatial Distributions of Energetic Electrons and Energetic Ions in the Tail Reconnection Region: Cluster Observations and PIC Simulations

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract High‐energy particles are prevalent in space, and magnetic reconnection is one of the physical processes responsible for their generation. The heating and acceleration of ions and electrons typically occur respectively in the ion diffusion region and the electron diffusion region.

Real‐Time Optimal Control of High‐Dimensional Parametrized Systems by Deep Learning‐Based Reduced Order Models

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT Steering a system towards a desired target in a very short amount of time is a challenging task from a computational standpoint. Indeed, the intrinsically iterative nature of optimal control problems requires multiple simulations of the state of the physical system to be controlled. Moreover, the control action needs to be updated whenever the
