Operator Inference for Physical and Generalized Surrogate Groundwater Modeling

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Groundwater flow and solute transport models, governed by partial differential equations (PDEs), are computationally intensive, particularly in large‐scale. Traditional numerical models are prohibitively expensive, and existing surrogate models often fail under out‐of‐distribution (OOD) conditions, such as unseen initial conditions, boundary ...

Non‐Invasive Imaging of Solute Redistribution Below Evaporating Surfaces Using 23Na‐MRI

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Saline water evaporation from porous media is a key phenomenon in the terrestrial environment and is linked to problems such as soil salinization and weathering of building materials. Recent modeling studies suggest the development of local instabilities due to density differences during evaporation in case of saturated porous media with high ...

DRL‐Based Joint Clustering and Trajectory Optimization for UAV‐Assisted Emergency Networks

IET Communications, Volume 20, Issue 1, January/December 2026.
6G is expected to see unprecedented data traffic surges. UAV‐assisted MEC aids emergency communications but faces challenges from dynamic user mobility and heterogeneous tasks. To address these, the proposed KM‐PPO integrates interference‐aware k‐means clustering (for user aggregation and initial UAV deployment) and PPO (for stable policy updates and ...

Task‐Specific Optimal Trajectory Planning of Dual‐arm Space Robot Based on Convex Optimization

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper presents a robust, task‐specific optimal trajectory planning framework for dual‐arm space robots. The method unifies two key problems—point‐to‐point grasping and continuous trajectory tracking—within an efficient optimization framework. Extensive comparative simulations on a highly redundant 14‐degree‐of‐freedom (14‐DoF) dual‐arm space robot
