Relative Stability and Local Curvature Analysis in Carbon Nanotori [PDF]

open access: yes, 2015
We introduce a concise formalism to characterize nanometer-sized tori based on carbon nanotubes and to determine their stability by combining {\em ab initio} density functional calculations with a continuum elasticity theory approach that requires only ...

A network dynamics approach to chemical reaction networks [PDF]

open access: yes, 2015
A crisp survey is given of chemical reaction networks from the perspective of general nonlinear network dynamics, in particular of consensus dynamics. It is shown how by starting from the complex-balanced assumption the reaction dynamics governed by mass
