For every n, we construct two arcs in the four-punctured sphere that have at least n intersections and which do not form spirals. This is accomplished in several steps: we first ...

We show that for every n there are two simple curves on the torus intersecting at least n times without the two curves folding or spiralling with respect to each other.

Abstract. The topology of β-sheets is defined by the pattern of hydrogenbonded strand pairing. Therefore, predicting hydrogen bonded strand partners is a fundamental step towards...
We consider the interactions between edges and intensity distributions in semi-open image neighborhoods surrounding them. Locally this amounts to a kind of figure-ground problem, ...
