The Dynamic Ion Motive Force Powering the Bacterial Flagellar Motor

open access: yesFrontiers in Microbiology, 2021
The bacterial flagellar motor (BFM) is a rotary molecular motor embedded in the cell membrane of numerous bacteria. It turns a flagellum which acts as a propeller, enabling bacterial motility and chemotaxis.

A Homogenization Method for Replacement Stator Models in an Aero-Engine

open access: yesAerospace, 2022
Generally, the high-fidelity finite element models of aero-engines comprise millions of degrees of freedom (DOFs). Although they can provide precise predictions of structural dynamics, the computational cost will be often unaffordable if appropriate ...
