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…
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…
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…
Sequencing of semiflexible polymers of varying bending rigidity using patterned pores
Rajneesh Kumar, Abhishek Chaudhuri, Rajeev Kapri
We study the translocation of a semiflexible polymer through extended pores with patterned stickiness, using Langevin dynamics simulations. We find that the consequence of pore pat…
Collective transport of weakly interacting molecular motors with Langmuir kinetics
Sameep Chandel, Abhishek Chaudhuri, Sudipto Muhuri
Filament based intracellular transport involves the collective action of molecular motor proteins. Experimental evidences suggest that microtubule (MT) filament bound motor protein…
