To determine saltern boundaries, vascular plant distributions were analyzed across nine transects through three tidal communities on the west coast of Florida: a salt marsh in St. Mark's National Wildlife Refuge, a dwarf mangal in upper Tampa Bay and a we... see more

We determine new upper bounds for the clique numbers of strongly regular graphs in terms of their parameters. These bounds improve on the Delsarte bound for infinitely many feasible parameter tuples for strongly regular graphs, including infinitely many p... see more

Let D be a set of n pairwise disjoint unit balls in Rd and P the set of their centers. A hyperplane H is an m-separator for D if every closed halfspace bounded by H contains at least m points from P. This generalizes the notion of halving hyperplanes, whi... see more

Can folding a piece of paper flat make it larger? We explore whether a shape S must be scaled to cover a flat-folded copy of itself. We consider both single folds and arbitrary folds (continuous piecewise isometries S?R2). The underlying problem is motiva... see more

We consider the Minimum Perimeter Polygon Problem (MP3): for a given set V of points in the plane, find a polygon P with holes that has vertex set V , such that the total boundary length is smallest possible. The MP3 can be considered a natural geometric&... see more

The article presents findings from an empirical study among patients and professionals involved in a preventive health program at a Danish hospital. It shows how patients enrolled in the program interact with health professionals in ways that challenge as... see more

We introduce the signless 1-Laplacian and the dual Cheeger constant on simplicial complexes.  The connection of its spectrum to the combinatorial properties like independence number,  chromatic number and dual Cheeger constant is investigated. O... see more

Contemporary society presents researchers with complex problems that often demand collaborative inquiry to extend the existing knowledge boundaries. Research networks give researchers access to to a wider pool of expertise in solving such complex problems... see more
