From aggressive driving to molecular motor traffic
Ambarish Kunwar, Andreas Schadschneider, Debashish Chowdhury
Motivated by recent experimental results for the step sizes of dynein motor proteins, we develope a cellular automata model for intra-cellular traffic of dynein motors incorporatin…
Collective traffic-like movement of ants on a trail: dynamical phases and phase transitions
A. Kunwar, A. John, K. Nishinari +2
The traffic-like collective movement of ants on a trail can be described by a stochastic cellular automaton model. We have earlier investigated its unusual flow-density relation by…
Dynamic instability of microtubules: effect of catastrophe-suppressing drugs
Pankaj Kumar Mishra, Ambarish Kunwar, Sutapa Mukherji +1
Microtubules are stiff filamentary proteins that constitute an important component of the cytoskeleton of cells. These are known to exhibit a dynamic instability. A steadily growin…
Power of the power-laws: lessons from unification of small and large time scales for evolution
Debashish Chowdhury, Dietrich Stauffer, Ambarish Kunwar
We develop a ``unified'' model that describes both ``micro'' and ``macro'' evolutions within a single theoretical framework. The eco-system is described as a dynamic network; the p…
