Rock fracture can ultimately be traced to atomic bond breakage. Taking quartz as a representative mineral, this paper employs molecular dynamics to identify the crack initiation and propagation mechanisms for single‐hole cases, as well as crack coalescence modes between double holes under compression, providing a physical basis for multiscale modeling ...

An intelligent inversion framework estimates the dilatancy angle of the surrounding rock from negative Poisson's ratio (NPR) anchor cable force histories. Numerical tunnel‐excavation simulations generate force data across a controlled dilatancy‐angle range, which are mapped to the target parameter using a sequential convolutional neural network (CNN ...

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).

This study demonstrates that the ultra‐low background radiation environment in deep underground laboratories significantly inhibits the proliferation of both normal nasopharyngeal epithelial cells (HNEPC) and nasopharyngeal carcinoma cells (HNE‐1) cells, with malignant cells exhibiting higher sensitivity.
