In this paper, we present an evaluation study of a set of registration strategies for the alignment of sequences of 3D dynamic contrast-enhanced magnetic resonance breast images. The accuracy of the optimal registration strategies was determined on u

We propose an extension of the algorithm for nonlinear dimensional reduction locally linear embedding (LLE) based on the usage of the geodesic distance (ISOLLE). In LLE, each data point is reconstructed from a linear combination of its n nearest neig

The concept of multiresolution analysis is applied to analyze the interference of scales in the reduction of the degrees of freedom for nonlinear partial differential equations. The selection of the relevant degrees of freedom is performed within a r

The density matrix renormalization group (DMRG) is a very accurate numerical technique developed to study strongly correlated many-body problems. A pedagogical exposition of the DMRG is provided, stressing its multiscaling character and the importanc

We investigate an operator renormalization group method to extract and describe the relevant degrees of freedom in the evolution of partial differential equations. The proposed renormalization group approach is formulated as an analytical method prov

Equilibrium aspects of molecular recognition of rigid biomolecules are investigated using coarse-grained lattice models. The analysis is carried out in two stages. First an ensemble of probe molecules is designed with respect to the target biomolecul
