A viscoelastic phase-field model for iceberg calving

Autor: Stocek, Jakub, Arthern, Robert J., Marsh, Oliver J.

Iceberg calving accounts for around half of the ice lost annually from Antarctica, but realistic representation of fracture and calving in large-scale ice sheet models remains a major unsolved problem in glaciology. We present a new phase-field visco

Report

Efficient quantitative assessment of robot swarms: coverage and targeting L\'{e}vy strategies

Autor: Duncan, Siobhan, Estrada-Rodriguez, Gissell, Stocek, Jakub, Dragone, Mauro, Vargas, Patricia A., Gimperlein, Heiko

Publikováno v: Bioinspiration & Biomimetics 17 (2022), 036006

Biologically inspired strategies have long been adapted to swarm robotic systems, including biased random walks, reaction to chemotactic cues and long-range coordination. In this paper we apply analysis tools developed for modeling biological systems

Studium interakcí mezi modifikovanými nukleobazemi pomocí NMR spektroskopie

Autor: Štoček, Jakub Radek

(EN) Nucleic acids are among the largest and most complex compounds in nature and without a doubt the most important molecules for the existence of life. Understanding the chemical behaviour and thermodynamic parameters of their building components e

Optimal operator preconditioning for pseudodifferential boundary problems

Autor: Gimperlein, Heiko, Stocek, Jakub, Urzua-Torres, Carolina

Publikováno v: Numerische Mathematik 148 (2021), 1-41

We propose an operator preconditioner for general elliptic pseudodifferential equations in a domain $\Omega$, where $\Omega$ is either in $\mathbb{R}^n$ or in a Riemannian manifold. For linear systems of equations arising from low-order Galerkin disc

Space-time adaptive finite elements for nonlocal parabolic variational inequalities

Autor: Gimperlein, Heiko, Stocek, Jakub

Publikováno v: Computer Methods in Applied Mechanics and Engineering 352 (2019), 137-171

This article considers the error analysis of finite element discretizations and adaptive mesh refinement procedures for nonlocal dynamic contact and friction, both in the domain and on the boundary. For a large class of parabolic variational inequali

Space-time fractional diffusion in cell movement models with delay

Autor: Estrada-Rodriguez, Gissell, Gimperlein, Heiko, Painter, Kevin J., Stocek, Jakub

Publikováno v: Mathematical Models and Methods in Applied Sciences 29 (2019), 65-88

The movement of organisms and cells can be governed by occasional long distance runs, according to an approximate L\'evy walk. For T cells migrating through chronically-infected brain tissue, runs are further interrupted by long pauses, and the aim h
