Let H be a set of n halfplanes in R in general position, and let k < n be a given parameter. We show that the number of vertices of the arrangement of H that lie at depth exactly k (i.e., that are contained in the interiors of exactly k halfplanes of H) is O(nk + nk). The bound is tight when k = Θ(n). This generalizes the study of Dey [Dey98], concerning the complexity of a single level in an a...

The complex biochemical interactions which occur between parasites and their host cells require elucidation for a clear understanding of how an infectious process develops. Whether the reactions between microorganisms and tissues occur directly or are mediated through secondary mechanisms has been the subject of considerable discussion (Sanford, Barnett, and Gott, 1960; Gilbert, 1960; Atkins, 1...
