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…
Competition of coarsening and shredding of clusters in a driven diffusive lattice gas
Ambarish Kunwar, Debashish Chowdhury, Andreas Schadschneider +1
We investigate a driven diffusive lattice gas model with two oppositely moving species of particles. The model is motivated by bi-directional traffic of ants on a pre-existing trai…
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…
Evolution of Spatially Inhomogeneous Eco-Systems: An Unified Model Based Approach
Ambarish Kunwar
Recently we have extended our the "unified" model of evolutionary ecology to incorporate the {\it spatial inhomogeneities} of the eco-system and the {\it migration} of individual o…
Evolutionary ecology in-silico:evolving foodwebs, migrating population and speciation
Dietrich Stauffer, Ambarish Kunwar, Debashish Chowdhury
We have generalized our ``unified'' model of evolutionary ecology by taking into account the possible movements of the organisms from one ``patch'' to another within the same eco-s…
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…
