Description
Myosin is a molecular motor that converts chemical energy to mechanical energy, thus generating force and movement in muscles and cells. Myosin interacts with two ligands, ATP (fuel) and actin filaments (motor’s tracks). Actomyosin interaction is ...

Description
Random anti-reflection structured surfaces (rARSS) have been reported to improve transmittance of optical-grade fused silica planar substrates to values greater than 99%. These textures are fabricated directly on the substrates using reactive-ion/...

Description
We demonstrate how the unusual mathematics of transfinite numbers, in particular, a nearly perfect realization of Hilbert's famous hotel paradox, manifests in the propagation of light through fractional vortex plates. It is shown how a fractional ...
