Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1
FEBS Open Bio, EarlyView.The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Determination of the Cable Span and Cable Deflection of Cable-Driven Parallel Robots
, 2017 S.106-116In this paper, a method is proposed to compute the so-called cable span, i.e. the space occupied by the cables when the robot is moving within its workspace. As the cables are attached to a mostly fixed point on the robot frame, the shape of the
