Pseudo-Riemannian symmetric spaces of signature (2,2)
Ines Kath, Matti Lyko
The paper classifies all four‑dimensional simply‑connected indecomposable non‑semisimple pseudo‑Riemannian symmetric spaces with signature (2,2), provides explicit models, computes…
Geometry-Induced Transport of Self-Aligning Chiral Bristlebots
Timo Wagner, Michael Himpel, Thomas Ihle +1
Active matter systems characterized by the interplay of chirality and self-alignment offer a rich landscape for non-equilibrium collective behaviors and the development of autonomo…
Dynamics of Aligning Active Matter: Mapping to a Schrödinger Equation and Exact Diagonalization
Tara Steinhöfel, Horst-Holger Boltz, Thomas Ihle
There has been recent interest in the relaxational modes of small-scale fully connected systems of aligning self-propelled particles (Spera et al., Phys. Rev. Lett. {\bf 132}: 0783…
An ErdÅs--Szekeres type result for words with repeats
Kyle Celano, Abigail Ollson, Niraj Velankar +1
We prove an ErdÅs--Szekeres type result for finite words over with repeated values. Specifically, we define a \emph{repeat} in a word to be an occurrence of a value w…
Potential and challenges of generative adversarial networks for super-resolution in 4D Flow MRI
Oliver Welin Odeback, Arivazhagan Geetha Balasubramanian, Jonas Schollenberger +9
4D Flow Magnetic Resonance Imaging (4D Flow MRI) enables non-invasive quantification of blood flow and hemodynamic parameters. However, its clinical application is limited by low s…
Critical gradient optimization for quasi-isodynamic stellarators
G. T. Roberg-Clark, P. Xanthopoulos, G. G. Plunk +1
We present new and updated methods for reducing transport caused by electrostatic ion temperature gradient (ITG) driven turbulence in quasi-isodynamic (QI) configurations. We first…
