Estimating Orientational Water Entropy at Protein Interfaces
(2012-02-09)The entropy of solvents significantly contributes to the stability of the native state of proteins. However, obtaining solvent entropies from molecular dynamics simulations remains a ... -
Multiphase coexistence with sequence fractionation in random block copolymers
(2012-01-16)Random binary block copolymers emerge from linking permanently and at random prepolymer blocks of two different chemical species A and B. The competitive interplay of conformational entropy, ... -
Dense Granular Fluids and the Granular Glass Transition
(2011-11-17)Driven granular fluids at finite density are investigated theoretically and numerically for nontrivial correlations and for the formation of an dynamically arrested, amorphous, i.e., glassy ... -
Low Temperature Phase of the m-component Spin Glass
(2011-09-15)We investigate the low temperature phase of a vector spin glass in the limit of large component numbers $m$ of the spins, where this model is expected to be replica symmetric. On a Bethe ... -
Statics and dynamics of solvent-free models for liquid bilayer membranes
(2011-05-31)Collective phenomena in lipid membranes, like pore formation and fusion, self-assembly, or lateral demixing of lipid mixtures, have attracted tremendous interest over the last years. Often, ... -
Orientational order and glassy states in networks of semiflexible polymers
(2011-02-01)Motivated by the structure of networks of cross-linked cytoskeletal biopolymers, the orientationally ordered phases in networks of randomly cross-linked semiflexible polymers are studied ... -
Aggregation and Gelation in Random Networks
(2010-06-23)In this thesis the formation, elasticity, and structure of randomly cross-linked networks is investigated analytically and with the help of computer simulations. In the first two chapters, ... -
Numerical simulations of wet granular matter
(2010-05-06)Wet granular matter is a useful system for studing the dynamics which emerge in systems far from thermal equilibrium. It is easily accessible by experiments as well as simulations. With the ... -
Real-time Magnetic Resonance Imaging
(2010-01-26)In this PhD thesis a generic solution for real-time MRI was developed based on a comprehensive analysis of the physical requirements. The method combines the fast low angle shot (FLASH) acquisition principle with a radial ... -
Entropy Production and Phase Transitions far from Equilibrium with Emphasis on Wet Granular Matter
(2008-11-14)This thesis investigates irreversible dynamics. It is shown analytically that the recent Fluctuation Theorem extends to relativistic dynamics. In the analytic consideration of non-relativistic ... -
Rapid Determination of High-Resolution Protein Structures by Solution and Solid-state NMR Spectroscopy
(2008-04-08)NMR spectroscopy provides high-resolution structural information of biomolecules in near-physiological conditions. Structural studies of proteins and nucleic acids are critical for understanding biological processes at ... -
Stucture Changes in Nephila Dragline: The Influence of Temperature, Humidity and Mechanical Load
(2007-06-05)The emphases of this thesis are the observation, the analysis and the interpretation of the response of Nephila dragline s crystalline parts to temperature, humidity and mechanical load. ... -
Pattern selection in the visual cortex
(2006-04-25)The orientation map in the primary visual cortex is an important model system for studying cortical development. By quantifying large sets of functional brain imaging data we find that the ... -
Grundzustandsstruktur ungeordneter Systeme und Dynamik von Optimierungsalgorithmen
(2005-12-12)Combinatorial optimization problems from Theoretical Computer Sciences and certain magnetic alloys (called spin glasses) both consist of particles or variables which are coupled by a large ... -
Phase behaviour of random copolymers and crosslinked homopolymer blends
(2005-11-25)The phase behaviour of molten linear random block copolymers and of randomly crosslinked homopolymer blends is studied in the framework of statistical mechanics based on microscopic models.In ... -
Critical dynamics of gelling polymer solutions
(2005-08-29)This thesis addresses critical dynamics of randomly crosslinked polymeric liquids within semi-microscopic models. Therefore, the well known Rouse- and Zimm model are generalized to random ... -
Stationary Properties of Driven Granular Gases
(2005-03-18)We study driven granular gases in two dimensions. First we present systems of smooth particles between two vibrating walls. For these intrinsically inhomogeneous systems we measure all ... -
Molecular dynamics of clathrin proteins at endocytic sites studied with evanescent-wave microscopy
(2004-10-04)Clathrin (consisting of a light chain and a heavy chain subunit) is a triskelion-shaped molecule that self-assembles into polyhedral lattices on cellular membranes. It has a pivotal role ... -
Einfache Modelle für komplexe Biomembranen
(2003-10-22)Biomembranes are complex two-dimensional fluids consisting of proteins and lipids. In this work, simple molecular models are developed, applied and discussed to describe the thermodynamic ... -
Superdiffusion in Scale-Free Inhomogeneous Environments
(2003-08-21)We investigate the impact of external potentials on superdiffusive random walks known as Lévy flights and show that even strongly superdiffusive transport is substantially affected by ...
