Shortest Paths with Pairwise-Distinct Edge Labels: Finding Biochemical Pathways in Metabolic Networks
Sandor Fekete, Tom Kamphans, Michael Stelzer
A problem studied in Systems Biology is how to find shortest paths in metabolic networks. Unfortunately, simple (i.e., graph theoretic) shortest paths do not properly reflect bioch…
Online Square Packing
Sandor P. Fekete, Tom Kamphans, Nils Schweer
We analyze the problem of packing squares in an online fashion: Given a semi-infinite strip of width 1 and an unknown sequence of squares of side length in [0,1] that arrive from a…
Coherent spin-current oscillations in transverse magnetic fields
R. Steinigeweg, S. Langer, F. Heidrich-Meisner +2
We address the coherence of the dynamics of spin-currents with components transverse to an external magnetic field for the spin-1/2 Heisenberg chain. We study current autocorrelati…
A variational approach to dislocation problems for periodic Schrödinger operators
Rainer Hempel, Martin Kohlmann
As a simple model for lattice defects like grain boundaries in solid state physics we consider potentials which are obtained from a periodic potential on with p…
Transport in the 3-dimensional Anderson model: an analysis of the dynamics on scales below the localization length
Robin Steinigeweg, Hendrik Niemeyer, Jochen Gemmer
Single-particle transport in disordered potentials is investigated on scales below the localization length. The dynamics on those scales is concretely analyzed for the 3-dimensiona…
Image sequence interpolation using optimal control
Kanglin Chen, Dirk A. Lorenz
The problem of the generation of an intermediate image between two given images in an image sequence is considered. The problem is formulated as an optimal control problem governed…
