Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas
Deep Underground Science and Engineering, EarlyView.This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors
Developmental Dynamics, EarlyView.Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A triple synergistic strategy (bismuth‐modified Zn@CNTF anode, helical electrode architecture, and self‐healing gel electrolyte) endows fiber‐shaped aqueous Zn‐ion batteries with outstanding stability. The device delivers a high energy density of 130.54 Wh·kg−1 and retains ≈90.2% of its initial capacity after 1000 dynamic bending cycles, representing a

Serration and Reversion Treatment in Al-10mass%Zn Alloy
The relationship between occurrence of serration and reversion heat treatment was studied by tensile test on Al-10mass%Zn alloy. Serration was observed for the furnace cooled specimen, but not for the as-quenched one and the shortly aged one, which ...

Harnessing Diversity: Majority‐Group Acculturation Predicts Creativity and Flourishing Over Time
European Journal of Social Psychology, EarlyView.ABSTRACT Creativity and flourishing are core aims of higher education (HE) institutions and government initiatives globally. Large‐scale projects have linked creativity and flourishing with cultural diversity, yet their associations with majority‐group acculturation (i.e., how members of dominant culture groups adopt minority‐cultural elements and/or ...

CFD analysis of wing trailing edge vortex generator using serrations
EPJ Web of Conferences, 2014 This study presents computational results of a NACA0012 base wing with the trailing edge modified to incorporate triangular serrations. The effect of the serrations were investigated in three stages, the deflection angle of the serration with respect to ...
