By means of multiscale molecular simulation, we here present a re-entrant disorder/order/disorder transition in diblock copolymer brushes.

A gap junction is a perforation connecting the cytoplasms of two neurons so that ions flow freely from one to the other. Thus when one neuron fires, it may induce its electrically coupled neighbors to fire. There is increasing evidence that gap junctions among pyramidal cell axons play a role in oscillations. The gamma oscillations (30-80 Hz) seen in hippocampal experiments in [8, 9] and models...
