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 ... -
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, ... -
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 ... -
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 ... -
Pattern Formation in Membranes with Quenched Disorder
(2015-01-23)The lateral heterogeneity in the plasma membrane of eukaryotic cells is an important factor for regulating biological functions. As opposed to plasma membranes, model membranes (either artificially prepared membranes, or ... -
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 ... -
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 ... -
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 ... -
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 ... -
Real-time MRI and Model-based Reconstruction Techniques for Parameter Mapping of Spin-lattice Relaxation
(2017-09-05)Magnetic resonance imaging (MRI) is a non-invasive technique widely used for imaging of humans and animals. It came into existence based on several fundamental inventions made in the 1970s. Since then, MRI has evolved into ... -
Rheology and Structure Formation in Complex Polymer Melts
(2019-04-17)Polymeric materials are ubiquitous in our modern lives. Their many applications in complex materials are accompanied by potentially huge benefits for technological advancement. These applications range from batteries, ... -
Rheology of frictional grains
(2016-08-19)This thesis deals with the description of flow and arrest of granular matter. Granular matter can undergo a rigidity transition — called jamming — that is mainly controlled by the applied stresses and the packing fraction ... -
Rheology of Weakly Attractive Soft Particles
(2016-12-14)We study the rheology of a soft particulate system with attractive interactions. Lees-Edwards boundary conditions are used to simulate a shear-controlled flow. Unlike repulsive systems, it is found that in systems with a ... -
Self-Organized Dynamics of Power Grids: Smart Grids, Fluctuations and Cascades
(2017-12-18)Climate change is one of the most pressing issues of our time and mitigating it requires a reduction of CO2 emissions. A big step towards achieving this goal is increasing the share of renewable energy sources, as the ... -
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, ... -
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 ... -
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. ... -
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 ... -
The interplay between curvature and composition in binary mixture lipid bilayers
(2016-04-08)In this work we investigate, via computer simulations with an implicit-solvent coarse-grained model, the interplay between curvature and composition in self- assembled lipid structures comprised by two lipid species with ...
