Foundation Models in Autonomous Driving: A Survey on Scenario Generation and Scenario Analysis
Yuan Gao, Mattia Piccinini, Yuchen Zhang +12
For autonomous vehicles, safe navigation in complex environments depends on handling a broad range of diverse and rare driving scenarios. Simulation- and scenario-based testing hav…
Discovering dynamics and parameters of nonlinear oscillatory and chaotic systems from partial observations
George Stepaniants, Alasdair D. Hastewell, Dominic J. Skinner +2
Despite rapid progress in live-imaging techniques, many complex biophysical and biochemical systems remain only partially observable, thus posing the challenge to identify valid th…
Dynamics, scaling behavior, and control of nuclear wrinkling
Jonathan A. Jackson, Nicolas Romeo, Alexander Mietke +5
The cell nucleus is enveloped by a complex membrane, whose wrinkling has been implicated in disease and cellular aging. The biophysical dynamics and spectral evolution of nuclear w…
First-order synchronization transition in a large population of strongly coupled relaxation oscillators
Dumitru Călugăru, Jan Frederik Totz, Erik A. Martens +1
Onset and loss of synchronization in coupled oscillators are of fundamental importance in understanding emergent behavior in natural and man-made systems, which range from neural n…
Expanding scroll rings in a model for the photosensitive Belousov-Zhabotinsky reaction
Arash Azhand, Rico Buchholz, Jan F. Totz +1
While free scroll rings are non-stationary objects that either grow or contract with time, spatial confinement can have a large impact on their evolution reaching from significant…
Control of transversal instabilities in reaction-diffusion systems
Sonja Molnos, Jakob Löber, Jan Frederik Totz +1
In two-dimensional reaction-diffusion systems, local curvature perturbations in the shape of traveling waves are typically damped out and disappear in the course of time. If, howev…
No-flux boundaries stabilize scroll rings in excitable media with negative filament tension
Arash Azhand, Rico Buchholz, Florian Buchholz +2
Scroll rings in an unbounded excitable medium with negative line tension undergo an instability ending eventually in a "turbulent" state, known as scroll wave (Winfree) turbulence.…
Spatial Confinement Causes Lifetime Enhancement and Expansion of Vortex Rings with Positive Filament Tension
Jan F. Totz, Harald Engel, Oliver Steinbock
We study the impact of spatial confinement on the dynamics of three-dimensional excitation vortices with circular filaments. In a chemically active medium we observe a decreased co…
