Based on theoretical analysis, the energy‐evolution behavior of the surrounding rock at various depths on the solid‐coal side of the 221303 material roadway during the “advancing‐toward‐mining” process was first clarified. Numerical simulations were then performed to validate and elaborate on the theoretical results.

Wonder as a Gateway to Science Meaning‐Making: Primary Pupils’ Narrative Journeys
ABSTRACT This study explores how wonder fosters transformative learning in science education for pupils (11–12 years old), creating meaning about cycles in nature. As an emotional and epistemic trigger, wonder may bridge everyday experiences with abstract scientific concepts by stimulating curiosity and creativity. Through a narrative writing task, the

Programmable crack dynamics engineering enables flexible strain sensors with high linearity
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...
