Angular momentum is highly regulated over the gait cycle and is important for maintaining dynamic stability and control of movement. However, little is known regarding how angular momentum is regulated on irregular surfaces, such as slopes, when the risk of falling is higher. This study examined the three-dimensional whole-body angular momentum patterns of 30 healthy subjects walking over a ran...

This paper is concerned with the relativistic Boltzmann equation without angular cutoff. We establish global-in-time existence, uniqueness and asymptotic stability for solutions nearby Maxwellian. work in case of a spatially periodic box. assume generic hard-interaction soft-interaction conditions on collision kernel that were derived by Dudyński Ekiel-Je $$\dot{\text {z}}$$ ewska (Comm. Math. ...

We present a rigorous criterion for stability of spiralling solitary structures in Hamiltonian systems incorporating the angular momentum integral and demonstrate its applicability to the spiralling of two mutually incoherent optical beams propagating in a photorefractive material.
