Schooling Trajectories and the Development of Brain Dynamics: A Comparative Study of Montessori and Traditional Education

Advanced Science, EarlyView.
We investigate whether Montessori and traditional schooling systems shape the developmental trajectory of large‐scale brain dynamics in different ways. We quantify the arrow of time (“non‐reversibility”) in neural activity during resting state and movie‐watching, revealing distinct maturational patterns.

MGDP: Mastering a Generalized Depth Perception Model for Quadruped Locomotion

Advanced Science, EarlyView.
ABSTRACT Perception‐based Deep Reinforcement Learning (DRL) controllers demonstrate impressive performance on challenging terrains. However, existing controllers still face core limitations, struggling to achieve both terrain generality and platform transferability, and are constrained by high computational overhead and sensitivity to sensor noise.

A Scalable BaTiO3 Nanocoating Strategy for Cost‐Effective and Stable Sulfide‐Based All‐Solid‐State Batteries

Advanced Science, EarlyView.
A rapid and scalable 10 min BaTiO3 (BTO) nanocoating uniformly encapsulates Li‐P‐S‐X sulfide electrolytes, serving as a dielectric “shield” that enhances air stability, reduces cost, and mitigates interfacial degradation. This multifunctional coating enables fast‐charging, durable all‐solid‐state batteries with ultralong cycling stability (>10 000 ...

Precise Tailoring 3D Printed In Situ Toughening Low‐k Microwave Transparent Structure via Thiol‐acrylate Chain Transfer Behavior

Advanced Science, EarlyView.
An in situ thiol–acrylate chain transfer‐mediated toughening strategy is introduced for Digital Light Processing (DLP) printing. Benefiting from its excellent printability, a printed gyroid lattice‐filled plate (100 µm wall thickness) achieves 92% transmittance at 10 GHz under a 50° incidence angle following structural optimization. ABSTRACT The unique
