Most prominent algorithms are based on spectral apporaches and identify metastable sets via the doimant eigenvalues of the transfer operator associated with the dynamical system under consideration. These algorithms require the dominant eigenvalues to be real-valued. However, for many types of dynamics, e.g. for non-reversible Markov chains, this condition is not met. In this paper we utilize the hitting time apporach to metastable sets and demonstrate how the wellknown statements about optimal metastable decompositions of reversible chains can be reformulated for non-reversible chains if one switches from a spectral approach to an exit time approach. The performance of the resulting algorithm is illustrated by numerical experiments on random walks on complex networks.}, language = {en} } @misc{SteinWeberZoellneretal., author = {Stein, Christoph and Weber, Marcus and Z{\"o}llner, Christian and Scharkoi, Olga}, title = {Fentanyl derivatives as pH-dependent opioid receptor agonists}, series = {European Patent Application, Bulletin 2013/08}, journal = {European Patent Application, Bulletin 2013/08}, language = {en} } @misc{SteinWeberScharkoietal., author = {Stein, Christoph and Weber, Marcus and Scharkoi, Olga and Deuflhard, Peter}, title = {Method and system for identifying compounds that bind and preferably activate a target opioid receptor in a pH-dependent manner}, series = {European Patent Application, Bulletin 2013/28}, journal = {European Patent Application, Bulletin 2013/28}, language = {en} } @article{KrebekvonAchaziSollederetal., author = {Krebek, von, Larissa K.

Usually, real-valued eigenvectors are mandatory for this type of algorithms. The Perron Cluster Analysis (PCCA+) is a well-known spectral clustering method of Markov chains. It is applicable for reversible Markov chains, because reversibility implies a real-valued spectrum. We extend this spectral clustering method also to non-reversible Markov chains and give some illustrative examples. The main idea is to replace the eigenvalue problem by a real-valued Schur decomposition. By this extension, non-reversible Markov chains can be analyzed. Furthermore, the chains need not have a positive stationary distribution. And additionally to metastabilities, dominant cycles and sinks can be identified, too.}, language = {en} } @misc{BujotzekSchuettNielsenetal., author = {Bujotzek, Alexander and Sch{\"u}tt, Ole and Nielsen, Adam and Fackeldey, Konstantin and Weber, Marcus}, title = {Efficient Conformational Analysis by Partition-of-Unity Coupling}, series = {Math Chem}, journal = {Math Chem}, issn = {1438-0064}, url = {http://nbn-resolving.de/urn:nbn:de:0297-zib-42570}, abstract = {Obtaining a sufficient sampling of conformational space is a common problem in molecular simulation.
