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AAAI 2026}}, title = {{{Structure-Aware Encodings of Argumentation Properties for Clique-width}}}, year = {{2026}}, } @unpublished{62721, abstract = {{We introduce the notion of contrastive ABox explanations to answer questions of the type "Why is a an instance of C, but b is not?".

We develop an appropriate notion of contrastive explanations for the special case of ABox reasoning with description logic ontologies, and analyze the computational complexity for different variants under different optimality criteria, considering lightweight as well as more expressive description logics.

For local and rational function fields, we also give precise formulae for the number of elementary-abelian extensions with a fixed discriminant divisor, which describe a local-global principle.

However, the environmental instability of dsRNA presents a major limitation to its field application. In this study, we evaluate two distinct dsRNA formulation strategies for improved stability and delivery: a bottom-up approach using chitosan-based interpolyelectrolyte complexes (IPEC) and a top-down approach employing functionalized mesoporous silica carriers (SBA-15). Both systems were comprehensively characterized in terms of size, surface potential, porosity, and release behavior. The results revealed that IPECs exhibited release kinetics that were approximately one order of magnitude faster than those of SBA-15 across all tested conditions. The two formulations significantly improved dsRNA stability against UV and heat exposure compared to free dsRNA. In feeding assays with P. chrysocephala, both carriers achieved comparable gene silencing efficacy, though dsRNA@IPEC induced more immediate effects, while dsRNA@SBA-15 displayed delayed but ultimately stronger reduction in consumed leaf area, consistent with its slower release kinetics. We demonstrate that despite structural and mechanistic differences, both delivery platforms effectively stabilized and delivered dsRNA, and offered distinct advantages depending on application needs.

To overcome thermal imbalance constraints, an innovative strategy leveraging plastic shell containment is proposed to elevate the expulsion-free heat input threshold. By applying a combined preheating and ramping current profile, a coordinated “shell-first, nugget-second” sequence is achieved. This mechanism creates a solid-state barrier prior to rapid fusion, effectively preventing expulsion. Experimental results demonstrate that while the reference constant-current schedule fails to maintain a process window under a 2 mm initial gap (IG) disturbance, the proposed strategy significantly enhances process stability. It increases the maximum expulsion-free heat input by 24 % (to 6338 J) under normal conditions and by 77 % (to 6482 J) under the IG condition. Crucially, the increased heat input drives nugget growth across all interfaces, achieving a penetration depth of 0.38 mm (48 % penetration ratio) in the low-carbon steel sheet under the gap condition. These findings validate the strategy’s effectiveness in ensuring weld quality and robustness, which is further confirmed by its transferability to a lowerresistivity DX54D cover sheet.}}, author = {{Yang, Keke and Männer, Leonhard and Wang, Zhuoqun and Olfert, Viktoria and Böhm, Yannic and Hein, David and Meschut, Gerson}}, issn = {{1526-6125}}, journal = {{Journal of Manufacturing Processes}}, number = {{Special issue entitled: ‘Trends on spot joining’ published in Journal of Manufacturing Processes.}}, pages = {{984--1000}}, publisher = {{Elsevier BV}}, title = {{{Process window expansion with transferable applicability in three-layer dissimilar steel resistance spot welding via expulsion prevention}}}, doi = {{10.1016/j.jmapro.2025.12.036}}, volume = {{157}}, year = {{2026}}, } @article{63401, author = {{Thommes, Kirsten and Mehic, Miro}}, issn = {{0965-8564}}, journal = {{Transportation Research Part A: Policy and Practice}}, publisher = {{Elsevier BV}}, title = {{{The persistence of default effects: Evidence from CO2 offsetting in cargo transportation}}}, doi = {{10.1016/j.tra.2025.104838}}, volume = {{204}}, year = {{2026}}, } @article{63418, abstract = {{Manufacturing tolerances have a measurable influence on the structural integrity of self-piercing riveted (SPR) joints in automotive applications, yet their quantitative impact on load-bearing behavior remains insufficiently resolved. This study establishes a validated hierarchical methodology to predict tolerance-dependent failure behavior of SPR joints, progressing from coupon to sub-component scale through an integrated experimental–numerical approach. Five critical manufacturing tolerances, including rivet length (±0.5 mm), rivet head position (±0.3 mm), orthogonality deviation (2.8° and 5°), lateral offset (up to 1.2 mm), and flange overlap reduction (up to 7.5 mm), were investigated. Steel–steel joints exhibited a higher sensitivity to tolerances by a factor of 2–3 compared to steel–aluminum joints. A unified effective rivet length concept was developed to consolidate the geometric effects of all tolerances into a single physically meaningful parameter, enabling load-bearing capacity prediction with R2 > 0.95 across all evaluated loading directions. The sub-component validation employing T-joint specimens indicates a 2–3 fold amplification of tolerance effects at critical structural regions, providing experimental evidence for the hierarchical scaling principle. The methodology was implemented in a tolerance-dependent CONSTRAINED_SPR3 formulation, providing >99 % computational efficiency improvement while maintaining a deviation in maximum force prediction within ±7 %. This framework enables the physically consistent representation of manufacturing variation within large-scale simulations and establishes a transferable basis for tolerance-resilient virtual vehicle development.}}, author = {{Olfert, Viktoria and Yang, Keke and Rochel, Philip and Bähr, Philipp and Hein, David and Sommer, Silke and Meschut, Gerson}}, issn = {{1526-6125}}, journal = {{Journal of Manufacturing Processes}}, number = {{Special issue entitled: ‘Trends on spot joining’ published in Journal of Manufacturing Processes.}}, pages = {{1250--1273}}, publisher = {{Elsevier BV}}, title = {{{Predictive modeling of tolerance-dependent failure behavior of self-pierce riveted joints: From coupon-level tests to sub-component validation}}}, doi = {{10.1016/j.jmapro.2025.12.058}}, volume = {{157}}, year = {{2026}}, } @article{63435, author = {{Claes, Leander and Winkler, Michael}}, issn = {{1468-1218}}, journal = {{Nonlinear Analysis: Real World Applications}}, pages = {{104580}}, publisher = {{Elsevier BV}}, title = {{{Describing smooth small-data solutions to a quasilinear hyperbolic-parabolic system by W 1,P energy analysis}}}, doi = {{10.1016/j.nonrwa.2025.104580}}, volume = {{91}}, year = {{2026}}, } @article{63436, author = {{de Souza, Sivoney Ferreira and Beresowski, Christina and Kosmella, Sabine and Ameixa, João and Pothineni, Bhanu Kiran and Keller, Adrian Clemens and Hartlieb, Matthias and Taubert, Andreas and Bald, Ilko}}, issn = {{2574-0970}}, journal = {{ACS Applied Nano Materials}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Nanocellulose Membranes for Plasmon-Enhanced Removal of Organic Pollutants from Water}}}, doi = {{10.1021/acsanm.5c04857}}, year = {{2026}}, }
