Freely relaxing polymers remember how they were straightened.
The relaxation of initially straight semiflexible polymers has been discussed mainly with respect to the longest relaxation time. The biologically relevant nonequilibrium dynamics on shorter times is comparatively poorly understood, partly because "initially straight" can be realized in manifold ways. Combining Brownian dynamics simulations and systematic theory, we demonstrate how different ex...
متن کاملThe state dependency effect of morphine on memory by behavioral and electrophysiological methods in freely moving rats
Endogenous opioid system agonists exert amnestic effects in different models of memory. It has been suggested that these amnestic effects may be linked indirectly to state-dependent learning. Accordingly pre-training administration of morphine can impair the retrieval of learned tasks in a state dependent manner, which is reversible by pre test morphine administration. In this study, state depe...

متن کاملAnomalous Dynamics of Polymer Films
This chapter reviews the recent experiments involving the dynamics of polymer films with thickness comparable to the gyration radius of the polymer, which overwhelmingly show that their glass transition temperature, Tg, depends on the film thickness and can sometimes differ significant from that of the bulk. The greatest mystery is the onset film thickness of this phenomenon being ~50 nm, much ...
متن کاملEffect of Nanopore Length on the Translocation Process of a Biopolymer: Numerical Study
In this study, we simulate the electrophoretic motion of a bio-polymer through a synthetic nanopore in the presence of an external bias voltage by considering the hydrodynamic interactions between the polymer and the fluid explicitly. The motion of the polymer is simulated by 3D Langevin dynamics technique by modeling the polymer as a worm-like-chain, while the hydrodynamic interactions are inc...
