Influenced by the complexity of volumetric imaging, there is a shortage of established datasets useful for benchmarking volumetric deep-learning models. As a consequence, new and existing models are not easily comparable, limiting the development of

Counting abelian extensions by Artin-Schreier conductor

Autor: Gundlach, Fabian

Let $G$ be a finite abelian $p$-group. We count $G$-extensions of global rational function fields $\mathbb F_q(T)$ of characteristic $p$ by the degree of what we call their Artin-Schreier conductor. The corresponding (ordinary) generating function tu

Deciphering the origin of spin current in spintronic terahertz emitters and its imprint on their electromagnetic radiation via time-dependent density functional theory

Autor: Kefayati, Ali, Ren, Yafei, Jungfleisch, M. Benjamin, Gundlach, Lars, Xiao, John Q., Nikolic, Branislav K.

Spin current flowing between femtosecond laser pulse (fsLP)-driven ferromagnetic metal and adjacent normal metal (NM) hosting strong spin-orbit coupling is invariably invoked to explain THz radiation believed to be emitted solely by NM layer. Despite

Localised ejection of dust and chunks on comet 67P/Churyumov-Gerasimenko: testing how comets work

Autor: Attree, Nicholas, Schuckart, Christian, Bischoff, Dorothea, Gundlach, Bastian, Blum, Jürgen

We extend an existing thermophysical activity model of comet 67P/Churyumov-Gerasimenko to include pressure buildup inside the pebbles making up the nucleus. We test various quantities of H$_{2}$O and CO$_{2}$, in order to simulate the material inside
