DOI: 10.1016/j.tust.2019.04.020
Abstract: Abstract Spalling is a typical failure mode encountered on the sidewalls after the tunnel face excavation of deep D-shaped tunnels or caverns. It significantly affects the safe and efficient construction and long-term stability of tunnels.… read more here.

DOI: 10.1214/20-ejp513
Abstract: For a Levy process $X$ on a finite time interval consider the probability that it exceeds some fixed threshold $x>0$ while staying below $x$ at the points of a regular grid. We establish exact asymptotic… read more here.
