Homoclinics for singular strong force Lagrangian systems
Advances in Nonlinear Analysis, 2019 We study the existence of homoclinic solutions for a class of Lagrangian systems ddt$\begin{array}{} \frac{d}{dt} \end{array} $(∇Φ(u̇(t))) + ∇uV(t, u(t)) = 0, where t ∈ ℝ, Φ : ℝ2 → [0, ∞) is a G-function in the sense of Trudinger, V : ℝ × (ℝ2 ∖ {ξ}) → ℝ ...

Balanced Walking Force Control for Walking Excavators Based on Dual Strong Tracking Kalman Filter
Applied SciencesThe operation of walking excavators on rugged terrain often leads to leg lift-off, which can result in uneven force distribution, accelerated structural wear, and even systemic instability.

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 ...

Physics Education, 2023 Abstract Introductory physics courses cover the gravitational and electromagnetic force in some detail, but the strong and weak nuclear forces are often given only a cursory treatment. This paper presents some ideas for teaching students about the strong force using practical hands-on demonstrations and using the strong force potential ...

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
