We examine the effect of subdividing the potential barrier along the reaction coordinate on Kramers’ escape rate for a model potential. Using the known supersymmetric potential approach, we show the existence of an optimal number of subdivisions that maximises the rate.

28 As the information bottleneck of nearly all auditory input that reaches the cortex, the 29 auditory thalamus serves as the basis for establishing auditory cortical processing streams. The 30 functional organization of the primary and non-primary subdivisions of the auditory thalamus is 31 not well characterized, particularly in awake primates. We have recorded from neurons in the 32 auditory...

We describe the structure of 2-connected non-planar toroidal graphs with no K3,3-subdivisions, using an appropriate substitution of planar networks into the edges of certain graphs called toroidal cores. The structural result is based on a refinement of the algorithmic results for graphs containing a fixed K5-subdivision in [A. Gagarin and W. Kocay, “Embedding graphs containing K5-subdivisions”...
