Tensor rank of the determinant and periodic triangulations of $\mathbb{R}^n$
We prove that in any $\mathbb{Z}^n$-periodic triangulation of $\mathbb{R}^n$ the number of $\mathbb{Z}^n$-orbits of $n$-dimensional simplices is at least the tensor rank of the $n$th determinant tensor. The latter is known to be at least $\frac{n^{n-1}}{(n-1)!}$, which is approximately $\frac{e^n}{\sqrt{2πn}}$ for large $n$. The triangulation is not assumed to be geometric, meaning that its simplices can be ``curved''. We also provide lower bounds for general spaces. A simplicial cell comple…

This book, "Last Boat from Tangier" by James von Leyden, published in 2020, seems nevertheless more relevant year after year. You'll know why when you follow the news.

Partly bright and sunny, but fully cold and with generous amounts of wind. “Brisk” doesn’t even begin to do it justice. Still, I am a freak and love this weather. It felt good to be out moving. #TeamShorts of course.
Walked briefly twice to bring my HR down a bit and then stopped to mug at this beautiful Great Blue Heron looking for their lunch. 🐟

I helgen ställde vi alla om klockan igen och numera är det normaltid som gäller i några månader framöver.

Integrating Background Knowledge in Medical Semantic Segmentation with Logic Tensor Networks
Semantic segmentation is a fundamental task in medical image analysis, aiding medical decision-making by helping radiologists distinguish objects in an image. Research in this field has been driven by deep learning applications, which have the potential to scale these systems even in the presence of noise and artifacts. However, these systems are not yet perfected. We argue that performance can be improved by incorporating common medical knowledge into the segmentation model's loss function. To…

Predictor-corrector method based on dynamic mode decomposition for tensor-train nonequilibrium Green's function calculations
The nonequilibrium Green's function (NEGF) formalism is a powerful tool to study the nonequilibrium dynamics of correlated lattice systems, but its applicability to realistic system sizes and long timescales is limited by unfavorable memory scaling. While compressed representations, such as the recently introduced quantics tensor train (QTT) format, alleviate the memory bottleneck, the efficiency of QTT-NEGF calculations is hindered by poor initializations and slow or unstable convergence of gl…
