TBM pressure models: calculation tools [PDF]
, 2015 Mechanized tunnel construction in soft ground has evolved significantly over the last 20 years, especially on the matter of settlement control. This was achieved by guiding the TBM operation to control the main factors that induce soil displacements ...

Arguments for a "U.S. Kamioka": SNOLab and its Implications for North American Underground Science Planning [PDF]
, 2006 We argue for a cost-effective, long-term North American underground science strategy based on partnership with Canada and initial construction of a modest U.S. Stage I laboratory designed to complement SNOLab.

Photon assisted tunneling as an origin of the Dynes density of states [PDF]
, 2010 We show that the effect of a high-temperature environment in current transport through a normal metal-insulator-superconductor tunnel junction can be described by an effective density of states (DOS) in the superconductor. In the limit of a resistive low-
