We vigorously condemn this practice and, effective immediately, will not consider manuscripts on human organ transplantation for publication unless appropriate non-coerced consent of the donor is provided and substantiated.

Interval Packing : the Vacant Interval Distribution

Starting at time 0, unit-length intervals arrive and are placed on the positive real line by a unit-intensity Poisson process in two dimensions; the left endpoints of intervals appear at the rate of 1 per unit time per unit distance. An arrival is accepted if and only if, for some given x, the interval is contained in 0 x and overlaps no interval already accepted. This stochastic, on-line inter...

Vacant Sets and Vacant Nets: Component Structures Induced by a Random Walk

Given a discrete random walk on a finite graph G, the vacant set and vacant net are, respectively, the sets of vertices and edges which remain unvisited by the walk at a given step t. Let Γ(t) be the subgraph of G induced by the vacant set of the walk at step t. Similarly, let Γ̂(t) be the subgraph of G induced by the edges of the vacant net. For random r-regular graphs Gr, it was previously est...
