A calibration ¢ is a differential form on a Riemannian manifold with two additional properties. First, the form should be closed under exterior differentiation. Second, it should be less than or equal to the volume form on each oriented submanifold (of the same dimension as the degree of the form ¢). Each calibration ¢ determines a geometry of submanifolds, namely those oriented submanifolds fo...
متن کاملStable isotope profiling of burnt wooden safety matches.
Arson is a significant problem around the world, and is a crime which results in a low number of convictions. The scene of an arson can be varied, commercial, residential or national park, and recently cases have been identified which were initiated by a lit match. Matches can be recovered from a scene, usually in a burnt condition. The benefit of analysing unburnt matches has been researched p...
متن کاملAttaching handles to Bryant surfaces
Complete minimal surfaces and constant mean curvature surfaces in Euclidean or hyperbolic space have been the object of much attention in recent years and particular efforts have been devoted in understanding the moduli space of such surfaces. More precisely, the surfaces we are interested in are complete, noncompact surfaces which may or may not be embedded but enjoy the somehow weaker, and sl...
متن کاملDo Weave Matches Imply Canvas Roll Matches?
Computational algorithms for measuring thread counts from scanned x-rays produce warp and weft thread count “maps” across entire paintings. Within the database of over 300 van Gogh paintings, we found a clique of 44 warp-weave-matched paintings. By reconstructing the smallest canvas section that could have produced this match, they must span the entire width of a commercial canvas roll (2+ mete...

The past two years have seen the rapid development of new recognition methods for protein structure prediction. These algorithms ’thread’ the sequence of one protein through the known structure of another, looking for an alignment that corresponds to an energetically favorable model structure. Because they are based on energy calculation, rather than evolutionary distance, these methods extend ...
