Kinematic Limit Analysis of Roof Stability for Elliptical Tunnels in Rock Masses
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 16, Page 3880-3896, November 2025.ABSTRACT Noncircular cross‐sections are commonly encountered in engineering practice; however, primary attempts to analyze roof stability have focused on circular and rectangular configurations. This study investigates the roof stability of elliptical tunnels with varying aspect ratios, employing two semi‐analytical approaches: piecewise linear and ...

Log‐Periodic Power Law Singularities in Landslide Dynamics: Statistical Evidence From 52 Crises
Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract Landslide movements typically show a series of progressively shorter quiescent phases, punctuated by sudden bursts during an acceleration crisis. We propose that such intermittent rupture phenomena can be described by a log‐periodic power law singularity model. Amounting mathematically to a generalization of the power law exponent from real to

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**
Berichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 163-179, August 2025.Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.
