Published in 2021 at "International Journal for Numerical Methods in Fluids"

DOI: 10.1002/fld.5032

Abstract: In the standard implementation of Borgnakke–Larsen (BL) rotation and translation energy exchange in DSMC not every rotational mode of each molecule is active in every collision. In some collisions, the rotation mode of one molecule… read more here.

Published in 2020 at "Experimental Brain Research"

DOI: 10.1007/s00221-020-05980-y

Abstract: Navigating crowded community spaces requires interactions with pedestrians that follow rectilinear and curvilinear trajectories. In the case of rectilinear trajectories, it has been shown that the perceived action opportunities of the walkers might be afforded… read more here.

Published in 2018 at "European Journal of Applied Physiology"

DOI: 10.1007/s00421-018-3846-7

Abstract: PurposeCollision sports are characterised by frequent high-intensity collisions that induce substantial muscle damage, potentially increasing the energetic cost of recovery. Therefore, this study investigated the energetic cost of collision-based activity for the first time across… read more here.
