In this paper, we show that a pointwise symmetric pre-isotonic preclosure function is uniquely determined the pairs of sets it separates. We then show that when the preclosure function of the domain is pre-isotonic and the pre-closure function of the codomain is pre-isotonic and pointwise-pre-symmetric, functions which separate only those pairs of sets which are already separated are precontinu...

Spontaneously occurring neuronal oscillations constitute a hallmark of developmental networks. They have been observed in the retina, neocortex, hippocampus, thalamus and spinal cord. In the immature hippocampus the so-called ‘giant depolarizing potentials’ (GDPs) are network-driven membrane oscillations characterized by recurrent membrane depolarization with superimposed fast action potentials...

This paper provides an analysis of a natural k-round tournament over n = 2' players, and demonstrates that the tournament possesses a surprisingly strong ranking property. The ranking property of this tournament is exploited by using it as a building block for efficient parallel sorting algorithms under a variety of different models of computation. Three important applications are provided. Fir...
