Lie group numerical integrators preserve the constants of motions defining the Lie group. Thus, they respect important physical laws of the dynamical system, such as unitarity and energy conservation in the context of quantum dynamical systems, for instance. In this article we develop a high-order commutator free Lie group integrator for non-autonomous differential equations evolving on quadratic Lie groups. Instead of matrix exponentials, which are expensive to evaluate and need to be approximated by appropriate rational functions in order to preserve the Lie group structure, the proposed method is obtained as a composition of Cayley transforms which naturally respect the structure of quadratic Lie groups while being computationally efficient to evaluate. Unlike Cayley-Magnus methods the method is also free from nested matrix commutators.}}, author = {{Wembe Moafo, Boris Edgar and Offen, Cristian and Maslovskaya, Sofya and Ober-Blöbaum, Sina and Singh, Pranav}}, journal = {{J.

Conventionally, a current control in dq-coordinates is utilized. At steady state, the resulting calculated reference arm voltages are sinusoidal, have identical amplitudes and show a phase shift of 120 degree to each other. For balanced grid inductors, the resulting grid currents also have the same amplitude. However, own simulations show that unbalanced grid inductors always lead to different grid current amplitudes (4% difference in this case). As a result, the averaged charging module powers differ and the peak DC-link capacitor voltage rises as well. In the first step, an adaptation of an existing zero-sequence voltage injection is proposed. For balanced grid inductors, it converges to the 3rd harmonic voltage injection which can reduce the peak-to-peak DC-link voltage ripple up by to 50% and balances the power between the phases. However, unbalanced grid inductors still lead to the same unbalanced grid currents of 4%. Therefore, a new method with 4 integrators based on linear regression is proposed to achieve sinusoidal grid currents for unbalanced inductors. The proposed method has a similar transient dynamic as the conventional dq control, but balances the grid currents nearly ideally. Simulation results of a 1MW cascaded H bridge and a scaled-down prototype verify the proposed method.}}, author = {{Unruh, Roland and Böcker, Joachim and Schafmeister, Frank}}, booktitle = {{2025 Energy Conversion Congress & Expo Europe (ECCE Europe)}}, keywords = {{Cascaded H-Bridge, Current Control, dq Transformation, Linear Regression, Unbalanced Inductors}}, location = {{Birmingham, United Kingdom}}, publisher = {{IEEE}}, title = {{{Three-Phase Instantaneous Current Controller for Unbalanced Grid Inductors Without DQ Transform for Cascaded H-Bridge Converters}}}, doi = {{10.1109/ecce-europe62795.2025.11238538}}, year = {{2025}}, } @article{63160, author = {{Rose, Hendrik and Schumacher, Stefan and Meier, Torsten}}, issn = {{2469-9950}}, journal = {{Physical Review B}}, number = {{24}}, publisher = {{American Physical Society (APS)}}, title = {{{Microscopic approach to the quantized light-matter interaction in semiconductor nanostructures: Complex coupled dynamics of excitons, biexcitons, and photons}}}, doi = {{10.1103/528f-7smh}}, volume = {{112}}, year = {{2025}}, } @article{63166, author = {{Jonas, Kristina and Abel, Miriam Katharina}}, issn = {{2193-6194}}, journal = {{Sprachförderung und Sprachtherapie in Schule und Praxis}}, number = {{4}}, pages = {{184--192}}, publisher = {{verlag modernes lernen}}, title = {{{Unterrichtsintegrierte Diagnostik im Förderschwerpunkt Sprache – ein Überblick}}}, volume = {{14}}, year = {{2025}}, } @book{63178, author = {{Jablonski, Simone}}, isbn = {{9783658477509}}, publisher = {{Springer Fachmedien Wiesbaden}}, title = {{{Modelling, Argumentation and Problem-Solving in the Context of Outdoor Mathematics}}}, doi = {{10.1007/978-3-658-47751-6}}, year = {{2025}}, } @article{63169, author = {{Taranto, E and Jablonski, S and Recio, T and Cunha, E and Ludwig, M and Mammana, MF}}, issn = {{2227-7102}}, number = {{3}}, title = {{{The Impact of a MOOC: Long-Term Analysis of Teachers' Learning Outcomes and Practices}}}, volume = {{15}}, year = {{2025}}, } @inbook{62646, author = {{Höink, Dominik and de Vos, J.

But LiNbO3 also exhibits a strong photorefractive effect, which limits the intensity of the optical fields involved. Various approaches to reduce the photorefractive effect have been investigated, such as increasing the temperature, doping the crystal or using different waveguide designs in LiNbO3. Here, we present an analysis of the approach to increase the photorefractive damage threshold by using different waveguide designs. Contrary to previous claims and investigations, our SHG measurements revealed no significant difference in resistance to photorefractive damage when comparing conventional Ti-doped channel waveguides and Ti-doped diced ridge waveguides in LiNbO3. Furthermore, we have investigated the effect of photorefractive cleaning and curing using a light field at 532 nm. Here, we observe a reduction in the photorefractive effect at room temperature during and after SHG measurements, which is an easy alternative to conventional approaches.}}, author = {{Kirsch, Michelle and Kießler, Christian and Lengeling, Sebastian and Stefszky, Michael and Eigner, Christof and Herrmann, Harald and Silberhorn, Christine}}, issn = {{0030-3992}}, journal = {{Optics & Laser Technology}}, publisher = {{Elsevier BV}}, title = {{{Photorefraction and in-situ optical cleaning in various types of LiNbO3 waveguides}}}, doi = {{10.1016/j.optlastec.2025.114260}}, volume = {{193}}, year = {{2025}}, } @inbook{63189, author = {{Schlieper, Hendrik}}, booktitle = {{Cálculo y error.
