Publication number: 20110264432Abstract: Modelling a molecule by means of a graph, said graph comprising vertices and edges, each edge having a specific type, and said graph having cyclic orderings on the half-edges about at least one of the vertices, said system comprising means for determining the cyclic orderings on the half-edges about said at least one vertex by means of the spatial coordinates of the constituent atoms of the molecule, and means for determining the type of each edge of the graph by means of the relative spatial location of the constituent atoms of the molecule. Thereby automatic classification, comparison, specification, analysis and/or prediction of molecular structures can be provided because these molecular structures are represented by explicit combinatorial objects, and descriptors can be derived from the graph constructed in this manner. The descriptors are automatically computable from molecular databases, such as PDB or CATH, with no qualitative human intervention or subjective criteria.Type: ApplicationFiled: July 1, 2009Publication date: October 27, 2011Applicant: Aarhus UniversitetInventors: Robert Penner, Jorgen Ellegaard Andersen, Michael Knudsen, Carsten Wiuf

Publication number: 20100150842Abstract: The present invention concerns the detection of resistance in a living organism, e.g., herbicide resistance in weed crops. Based on non-separated compounds obtained from an organism, e.g., an extract from a plant, a color development is generated.
