Stochastic resonance in a model of a periodically driven DNA : Multiple transitions, scaling and sequence dependence
Ramu Kumar Yadav, M. Suman Kalyan, Rajeev Kapri +1
We numerically study stochastic resonance in the unzipping of a model double-stranded DNA by a periodic force. We observe multiple peaks in stochastic resonance in the output signa…
Driven translocation of a semiflexible polymer through a conical channel in the presence of attractive surface interactions
Andri Sharma, Rajeev Kapri, Abhishek Chaudhuri
We study the translocation of a semiflexible polymer through a conical channel with attractive surface interactions and a driving force which varies spatially inside the channel. U…
Extension and dynamical phases in random walkers depositing and following chemical trails
Subhashree Subhrasmita Khuntia, Abhishek Chaudhuri, Debasish Chaudhuri
Active walker models have proved to be extremely effective in understanding the evolution of a large class of systems in biology like ant trail formation and pedestrian trails. We…
Driven translocation of a flexible polymer through an interacting conical pore
Rajneesh Kumar, Abhishek Chaudhuri, Rajeev Kapri
We study the driven translocation of a flexible polymer through an interacting conical pore using Langevin dynamics simulations. We find that, for a fixed value of externally appli…
Deconstructing the role of myosin contractility in force fluctuations within focal adhesions
Debsuvra Ghosh, Subhadip Ghosh, Abhishek Chaudhuri
Force fluctuations exhibited in focal adhesions (FAs) that connect a cell to its extracellular environment, point to the complex role of the underlying machinery that controls cell…
Morphological and dynamical properties of semiflexible filaments driven by molecular motors
Nisha Gupta, Abhishek Chaudhuri, Debasish Chaudhuri
We consider an explicit model of a semiflexible filament moving in two dimensions on a gliding assay of motor proteins, which attach to and detach from filament segments stochastic…
