Apical transport gets motorized

Knock twice before invading eisseria meningitidis , also known as meningococcus, is a pathogen with a nasty habit of forcing normally nonphagocytic endothelial cells to engulf it, allowing the bacterium to penetrate cellular barriers. Hoffmann et al. now demonstrate on page 133 that N. meningitidis activates two distinct signaling pathways in host cells to cause actin cytoskeleton reorganizatio...

Bicycle Curves

In this paper we examine bicycle curves from the point of view of Fourier series. We analyze necessary and sufficient conditions for a circle to admit an infinitesimal deformation as a bicycle curve with rotation number ρ and derive conditions equivalent to those obtained by Tabachnikov. We then show that whenever ρ ∈ Q is not 1 2 , that there is no such deformation. Introduction Two closed cur...

Full Bicycle Dynamic Model for Interactive Bicycle Simulator

An interactive bicycle simulator with six degrees of freedom motion system could bring the rider a very realistic riding feeling. An important component of the simulator is the full bicycle dynamic model that simulated the two-wheeled bicycle dynamics. It consists of two slightly coupled submodels: The stability submodel and the vibration submodel. The stability submodel solves the stability of...
