This study develops a closed‐form solution for stress analysis of shallow‐buried large‐diameter compressed air energy storage (CAES) chambers, explicitly incorporating free surface, lateral pressure, and gravity gradient effects. Validated against numerical simulations, the solution accurately captures stress redistribution and reveals upward migration

Developing a universal tunnel span classification from global tunnel databases
A universal tunnel span classification system is introduced that incorporates tunnel span, cross‐sectional area, typical tunnel types, and intended uses. Representative flatness ratio values are also provided for each span class. The classification is derived from a comprehensive database of 450 tunnel profiles from 47 countries.

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 ...

Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Three‐dimensional observation of the muscle–tendon integration process in mouse embryos
Abstract Background Muscle–tendon integration is a crucial step in the morphogenesis of the vertebrate locomotion system. As the limb muscle and tendon progenitor cells derive from distinct embryonic origin, their integration requires precise mutual positioning.
