BAR domains are highly conserved protein domains participating in a diversity of cellular processes that involve membrane remodeling. The mechanisms underlying such remodeling are debated. For the relatively well-studied case of amphiphysin N-BAR domain, one suggested mechanism involves scaffolding, i.e., binding of a negatively charged membrane to the protein's positively charged curved surfac...

This paper presents the design and analysis of a reduced degree-of-freedom Robotic Modular Leg (RML) mechanism used to construct a quadruped robot. This mechanism enables the robot to perform forward and steering locomotion with fewer actuators than conventional quadruped robots. The RML is composed of a double four-bar mechanism that maintains foot orientation parallel to the base and decouple...

Detailed morphological analyses have identified a number of different mechanical pathways by which the morphologically complex cranial system of fishes can achieve mouth opening and hyoid depression. However, many of these proposed mechanisms remain untested. Furthermore, very little is known about the precise timing of activity of each of these mechanisms, and about the magnitude of each mecha...

A computer-applicable linear mathematical model has been developed to determine Burmester’s curves for infinitely close relative positions (cubic of stationary curvature), which indirectly uses Carter-Hall’s circle. By varying a free parameter and using elements kinematic analytical geometry, an incomparably simpler solution is achieved than that obtained by the third-degree equations Burmester...
