2014 A mean field theory of the collapse of grafted chains (consisting of N monomers) in a poor solvent is presented. The collapse behaviour of nonoverlapping grafted chains is identical to that of free coils but with no phase separation. This « strong » collapse, in which the coil radius R decreases continuously from R ~ N3/5 in a good solvent to R ~ N1/3 in a poor solvent, is replaced by « we...

In the present study, the onset of double diffusive reaction-convection in a uid layer with viscous fluid, heated and salted from below subject to chemical equilibrium on the boundaries, has been investigated. Linear and nonlinear stability analysis have been performed. For linear analysis normal mode technique is used and for nonlinear analysis minimal representation of truncated Fourier serie...

Layer 3 of the medial entorhinal cortex is a major gateway from the neocortex to the hippocampus. Here we addressed structure-function relationships in medial entorhinal cortex layer 3 by combining anatomical analysis with juxtacellular identification of single neurons in freely behaving rats. Anatomically, layer 3 appears as a relatively homogeneous cell sheet. Dual-retrograde neuronal tracing...
