Brownian dynamics simulation of knot expansion. (A) The shown dependence of 71 knot size on time was obtained by combining four spans of the expansion 2.5 ms each. The initial conformations for each span were obtained by applying a proper stretching force to the chain ends. The simulation corresponds to the chain effective diameter of 0.1a. The average displacements of the knot center of mass over the time spans are shown at the button of the plot. (B) Initial expansion of very tight conformation of 71 knot created by the stretching force of 250. The simulation corresponds to the chain effective diameter of 0.02a.
