Lunar Tractive Forces and Renal Stone Incidence by Spyridon Arampatzis, George N. Thalmann, Heinz Zimmermann, Aristomenis K. Exadaktylos

“…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. …”

The Juno mission as a probe of long-range new physics by Praniti Singh, Shi Yan, Itamar J. Allali, JiJi Fan, Lingfeng Li

“…The spacecraft is the Juno orbiter, and ten of its early orbits already allow a precise determination of the Jovian gravitational field. We use the shift in the precession angle as a proxy to test non-gravitational interactions between Juno and Jupiter. …”

The 5D Standing Wave Braneworld with Real Scalar Field by Merab Gogberashvili, Pavle Midodashvili

“…The model represents the brane which bounds collective oscillations of gravitational and scalar field standing waves. These waves are out of phase; that is, the energy of oscillations passes back and forth between the scalar and gravitational waves. …”

A hypercontinuous hypersmooth Schwarzschild line element transformation by Robert A. Herrmann

“…The transformation is an ideal transformation in that in the natural world the transformation is conceived of as occurring at an unknown moment in the evolution of a gravitationally collapsing spherical body with radius greater than but near to the Schwarzsclfild radius. …”
