Reinforcement learning‐enhanced adaptive sliding mode controller for underground articulated vehicles trajectory tracking

Deep Underground Science and Engineering, EarlyView.
RL‐SMC couples a reinforcement learning agent with a sliding mode controller, where the agent online‐modulates the sliding mode parameters according to the vehicle's tracking state. A curvature‐aware preview term is further embedded to shift control from reactive correction to proactive maneuvering, enabling the articulated vehicle to anticipate sharp ...

Real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection: Combined low‐field nuclear magnetic resonance and multifractal approach

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates the real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection. Under in‐situ hydrostatic pressure, the water invasion front advances progressively along the axial direction as the injection pressure increases stepwise, tracked in real time by nuclear magnetic ...

A hierarchical adaptive strategy for selecting rheological models in intelligent backfill mining pipeline transportation systems

Deep Underground Science and Engineering, EarlyView.
This graphical abstract presents a hierarchical adaptive strategy for selecting rheological models in intelligent backfill pipeline transportation. Temperature, fly ash content, and water‐cement ratio jointly influence slurry rheological nonlinearity, which is quantified using the Model Fidelity Gain (ΔR2).

Harnessing Thin‐Film Solid‐State Electrolytes: Enabling Breakthroughs in All‐Solid‐State Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration highlighting the advantages of transitioning from traditional thick solid‐state electrolytes (SSEs) to thin‐film SSEs. Thinning the electrolyte enables higher ionic conductivity, reduced interfacial polarization, improved flexibility, compact electrode contact, and enhanced energy density, offering a promising pathway toward high‐
