An Area Rescaling Ansatz and Black Hole Entropy from Loop Quantum Gravity
Published 2019-01-01“…Considering the possibility of ‘renormalization’ of the gravitational constant on the horizon, leading to a dependence on the level of the associated Chern-Simons theory, a rescaled area spectrum is proposed for the nonrotating black hole horizon in loop quantum gravity. …”

Lunar Tractive Forces and Renal Stone Incidence
Published 2011-01-01“…Little is known about the influence of potential environmental triggers such as lunar gravitational forces. We conducted a retrospective study to test the hypothesis that the incidence of symptomatic renal colics increases at the time of the full and new moon because of increased lunar gravitational forces. …”
