The influence of membrane bound proteins on phase separation and coarsening in cell membranes

Autor: Witkowski, Thomas, Backofen, Rainer, Voigt, Axel

Publikováno v: Physical chemistry, chemical physics 2012;14:14509–14515, ISSN: 1463-9076

A theoretical explanation of the existence of lipid rafts in cell membranes remains a topic of lively debate. Large, micrometer sized rafts are readily observed in artificial membranes and can be explained using thermodynamic models for phase separat

Dissertation/ Thesis

Software concepts and algorithms for an efficient and scalable parallel finite element method

Autor: Witkowski, Thomas

Software packages for the numerical solution of partial differential equations (PDEs) using the finite element method are important in different fields of research. The basic data structures and algorithms change in time, as the user\'s requirements

Report

A multi-mesh finite element method for Lagrange elements of arbitrary degree

Autor: Witkowski, Thomas, Voigt, Axel

We consider within a finite element approach the usage of different adaptively refined meshes for different variables in systems of nonlinear, time-depended PDEs. To resolve different solution behaviours of these variables, the meshes can be independ

Report

Particles on curved surfaces - a dynamic approach by a phase field crystal model

Autor: Backofen, Rainer, Voigt, Axel, Witkowski, Thomas

Publikováno v: Phys. Rev. E 81, 025701(R) (2010)

We present a dynamic model to study ordering of particles on arbitrary curved surfaces. Thereby the particles are represented as maxima in a density field and a surface partial differential equation for the density field is solved to the minimal ener
