Basketball passing movements with and without head fakes were examined in a reaction-time paradigm. Participants were generally instructed to initiate the movement as fast and accurately as possible, while try-harder instructions were presented in 25 % of trials, prompting participants to mobilize all their cognitive resources to perform even faster. To investigate if athletic expertise modulates the potential effects of effort mobilization, basketball novices and experienced players were tested. Results demonstrated that try-harder instructions generally improved participants’ performance, facilitating faster response initiation times and movement execution, as well as a specific reduction in initiation time variability. Novices benefited more than experienced players, indicating that effort results in greater improvement when complex motor actions (for example, passes with head fakes) are not yet fully stabilized and lack automated fluency. This pattern suggests that effort enhances performance in complex actions when performance is limited by the amount of cognitive capacity available, supporting the coordination of partly conflicting movement components within tight temporal constraints. The findings extend previous research on effort mobilization from simple to complex motor tasks. Try-harder instructions appear to enhance performance primarily by reducing attentional lapses rather than generally improving processing speed. Future research should investigate the effectiveness of effort mobilization in experienced athletes in situations of high concurrent cognitive load.}}, author = {{Böer, Nils Tobias and Steinborn, Michael B. and Weigelt, Matthias and Güldenpenning, Iris}}, issn = {{1469-0292}}, journal = {{Psychology of Sport and Exercise}}, keywords = {{Effort, Try-harder instruction, Deception, Basketball, Head fake, Fake production}}, publisher = {{Elsevier BV}}, title = {{{Mobilizing effort in complex motor tasks: Try-harder instructions in deceptive actions}}}, doi = {{10.1016/j.psychsport.2026.103083}}, volume = {{84}}, year = {{2026}}, } @inbook{60342, author = {{Wehde, Janis and Bloh, Bea and Homt, Martina}}, booktitle = {{Handlungsorientierung in der Ausbildung von Lehrkräften und pädagogischen Fachkräften - Konzeptionen, Herausforderungen & Forschungsperspektiven}}, editor = {{Vogelsang, Christoph and Grotegut, Lea and Bruns, Julia and Riese, Josef and Fechner, Sabine}}, publisher = {{Waxmann}}, title = {{{Das Verhältnis zwischen politischer Involviertheit und professioneller Handlungskompetenz zur unterrichtlichen Gestaltung demokratischer Lerngelegenheiten}}}, doi = {{10.31244/9783818851057}}, volume = {{2}}, year = {{2026}}, } @article{64864, abstract = {{Probing novel properties, arising from twisted interfaces, has traditionally relied on the stacking of exfoliated two-dimensional materials and the spontaneous formation of van der Waals bonds. So far, investigations involving intimate covalent or ionic bonds have not been a focus. Yet, we show here that an established technique, involving thermocompressional wafer bonding, works well for creating twisted non-van der Waals interfaces. We have successfully bonded z-cut lithium niobate single crystals to create ferroelectric oxide interfaces with strong polar discontinuities and have mapped the associated emergent interfacial conductivity. In some instances, a dramatic change in microstructure occurs, involving local dipolar switching. A twist-induced collapse in the capability of the system to effec8tively screen interfacial bound charge is implied. Importantly, this only occurs around specific moiré twist angles with sparse coincident lattices and associated short-range aperiodicity. In quasicrystals, aperiodicity is known to induce pseudo-bandgaps and we suspect a similar phenomenon here.}}, author = {{Rogers, Andrew and Holsgrove, Kristina and Schäfer, Nils A. and Koppitz, Boris and McCluskey, Conor J. and Yedama, Shivani and Lynch, Ronan and Sloan, Keelan and Porter, Barry and Sykes, Adam and Catalan Daniels, Alex and Silva, Romualdo S. and Bruno, Flavio Y. and Seddon, Sam D. and Lu, Haidong and Rüsing, Michael and Fink, Christa and Fahler-Muenzer, Philipp and Fearn, Sarah and Heutz, Sandrine E.

This describes a dynamical transition between two invariant sets where every $δ$-neighborhood of the first set contains an initial condition with $ω$-limit in the second set. Thus, we prove a theorem that allows the systematic creation of hierarchical networks that are excitable on the top level, and heteroclinic on the lower level.

In this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create polymer gel dots through the process of photopolymerization that serve as a support for the catalyst. The resulting gel-bound organocatalysts were assembled within a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion of the product was assessed using 1H NMR spectroscopy as an offline analytical method over a duration of 8 h. The findings indicated that highly reactive aldehydes achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts. Furthermore, these results were juxtaposed with previously published data derived from alternative synthetic methodologies, revealing that the continuous microfluidic reactions employing integrated organocatalysts within polymer networks exhibited significantly higher conversions with reduced reaction times (8 h) at the same temperature (50 °C). Additionally, the influence of different geometries (round, triangular, and square) of the gel dots on catalytic activity was investigated, with round and square gel dots demonstrating slightly superior performance compared with triangular gel dots, attributed to their increased surface area. Moreover, an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained stable for 5 days before experiencing a slight decline due to product accumulation on the gel dots.}}, author = {{Killi, Naresh and Kumar, Amit and Nebhani, Leena and Obst, Franziska and Richter, Andreas and Reineke Matsudo, Bernhard and Zentgraf, Thomas and Kuckling, Dirk}}, issn = {{2470-1343}}, journal = {{ACS Omega}}, number = {{9}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Integrating an Organocatalyst into a Polymeric Gel Framework for the Continuous Microflow Baylis–Hillman Reaction}}}, doi = {{10.1021/acsomega.5c09476}}, volume = {{11}}, year = {{2026}}, } @article{61523, abstract = {{AbstractMetasurface holography offers a powerful approach for manipulating wavefronts at the nano and micro scale. Extensive research has been conducted to enhance the multiplexing capacity for diverse wavefronts. However, the independence of multiplexed channels is fundamentally restricted in techniques using single‐layer metasurfaces, resulting in unavoidable crosstalk and the need for post‐filtering of the output wavefronts. Here, a universal wavefront multiplexing concept is presented based on non‐injective transformation. By employing joint optimization on two metasurfaces, different channels can be independently designed without any constraints on the output wavefronts. To validate this approach, ultra‐compact orbital angular momentum (OAM) sorters are designed. In these experiments, the output beams from different channels can be independently mapped to 2D positions with high fineness. In another application of wavefront‐multiplexed holography, 10‐channel multiplexing is experimentally achieved with minimal crosstalk and without the need for post‐processing. These results demonstrate the independence between channels enabled by the non‐injective transformation in the method. The precise wavefront control and high multiplexing capacity underscore its potential for scalable wavefront manipulation devices.}}, author = {{Jin, Xiao and Zentgraf, Thomas}}, issn = {{0935-9648}}, journal = {{Advanced Materials}}, publisher = {{Wiley}}, title = {{{Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation}}}, doi = {{10.1002/adma.202511823}}, volume = {{38}}, year = {{2026}}, } @inproceedings{64872, author = {{Buhl, Heike M. and Fisher, Josephine Beryl and Rohlfing, Katharina J.}}, booktitle = {{Proceedings of the 3rd TRR 318 Conference: Contextualizing Explanations}}, editor = {{Cimiano, Philipp and Paassen, Benjamin and Vollmer, Anna-Lisa}}, publisher = {{Bielefeld University Press}}, title = {{{Cognitive and Interactive Adaptivity to the Explainee in an Explanatory Dialogue: An Experimental Study}}}, doi = {{10.64136/gumb4700}}, year = {{2026}}, } @article{35700, author = {{Webersen, Yvonne and Delle, Anna Luisa}}, journal = {{Plus Lucis}}, pages = {{20--23}}, title = {{{Physikalische Pseudowissenschaften entlarven am Beispiel von „WaveGuard – der Handyhülle für den gesunden Schlaf“}}}, volume = {{01/2026}}, year = {{2026}}, } @inbook{57744, author = {{Büttner, Denise}}, booktitle = {{Subjektivierungstheoretische Fachunterrichtsforschung – Erziehungswissenschaft und Fachdidaktiken im Gespräch}}, editor = {{Kuhlmann, Nele and Rabenstein, Kerstin and Roose, Hanna}}, publisher = {{Universitätsverlag Göttingen}}, title = {{{Wie Deutschunterricht zum ‚monolingualen Normraum der Fähigen‘ wird - Ein Blick auf sprachbezogene Subjektivierung im Medium der unterrichtlichen Sache}}}, volume = {{23}}, year = {{2026}}, } @book{36851, abstract = {{Wie kann sozialpädagogisches Handeln erlernt und gelehrt werden?

It is even known that modern SAT solvers work efficiently on instances of small treewidth. Since these solvers are widely applied, research interests in compact encodings into (Q)SAT for solving and to understand encoding limitations. Even more general is the graph parameter clique-width, which unlike treewidth can be small for dense graphs. Although algorithms are available for clique-width, little is known about encodings. We initiate the quest to understand encoding capabilities with clique-width by considering abstract argumentation, which is a robust framework for reasoning with conflicting arguments. It is based on directed graphs and asks for computationally challenging properties, making it a natural candidate to study computational properties. We design novel reductions from argumentation problems to (Q)SAT. Our reductions linearly preserve the clique-width, resulting in directed decomposition-guided (DDG) reductions. We establish novel results for all argumentation semantics, including counting. Notably, the overhead caused by our DDG reductions cannot be significantly improved under reasonable assumptions.}}, author = {{Mahmood, Yasir and Hecher, Markus and Groven, Johanna and Fichte, Johannes K.}}, booktitle = {{Pre-print of paper accepted at AAAI 2026}}, title = {{{Structure-Aware Encodings of Argumentation Properties for Clique-width}}}, year = {{2026}}, } @unpublished{62721, abstract = {{We introduce the notion of contrastive ABox explanations to answer questions of the type "Why is a an instance of C, but b is not?".
