Bite force data suggests relationship between acrodont tooth implantation and strong bite force [PDF]
PeerJ, 2020 Extant and extinct reptiles exhibit numerous combinations of tooth implantation and attachment. Tooth implantation ranges from those possessing roots and lying within a socket (thecodonty), to teeth lying against the lingual wall of the jawbone ...

Weak-Strong Uniqueness for Compressible Magnetohydrodynamic Equations with Coulomb Force
Advances in Mathematical Physics, 2021 In this paper, we consider the two-dimensional compressible magnetohydrodynamic system with Coulomb force. We apply the method of relative entropy to establish the weak-strong uniqueness property of this system.

Strong geometry dependence of the Casimir force between interpenetrated rectangular gratings
Nature Communications, 2021 The geometry dependence of the Casimir force could enable applications in nanomechanical systems if the effects can be enhanced. Here, the authors demonstrate that the Casimir force between two interpenetrating nanoscale gratings can exceed the proximity
