DNA origami in particular provides unique self‐assembly properties, not only enabling a vast variety of functionalization schemes but also presenting a promising route to fabricate large‐scale, bottom‐up nanostructured arrays. This approach has comparable precision to electron beam lithography but avoids slow and expensive patterning steps. However, self‐assembly of lattices with high order and well‐defined periodicity requires careful tuning of the deposition parameters and interactions involved, which has been done mostly on mica so far. As mica is not compatible with standard microfabrication processes, we investigate here the assembly of DNA origami lattices on the most general microfabrication material, that is, silicon wafers, which has turned out to be rather challenging. We study how the forming of polycrystalline 2D‐fishnet‐type lattices is influenced by different incubation conditions and strengths of the origami–origami and origami‐surface interactions, with the aim to create large‐scale single‐crystalline lattices. The lattices are characterized by atomic force microscopy and analyzed for precision of formation, achievable domain size, and surface coverage of well‐formed lattices. Thanks to the silicon substrate, these DNA origami lattices can be further combined with traditional microfabrication processes to turn them, for example, into metamaterials with novel optical properties.</jats:p>"}],"language":[{"iso":"eng"}],"article_number":"e202500813","doi":"10.1002/sstr.202500813","publication_identifier":{"issn":["2688-4062","2688-4062"]},"author":[{"last_name":"Järvinen","first_name":"Heini","full_name":"Järvinen, Heini"},{"first_name":"Johannes M.","last_name":"Parikka","full_name":"Parikka, Johannes M."},{"full_name":"Rajapaksha, R.

For example, in a citation network, nodes representing \"Paper\" or \"Author\" may include attributes like keywords or affiliations. A critical machine learning task on these graphs is node classification, which is useful for applications such as fake news detection, corporate risk assessment, and molecular property prediction. Although Heterogeneous Graph Neural Networks (HGNNs) perform well in these contexts, their predictions remain opaque. Existing post-hoc explanation methods lack support for actual node features beyond one-hot encoding of node type and often fail to generate realistic, faithful explanations. To address these gaps, we propose DiGNNExplainer, a model-level explanation approach that synthesizes heterogeneous graphs with realistic node features via discrete denoising diffusion. In particular, we generate realistic discrete features (e.g., bag-of-words features) using diffusion models within a discrete space, whereas previous approaches are limited to continuous spaces. We evaluate our approach on multiple datasets and show that DiGNNExplainer produces explanations that are realistic and faithful to the model's decision-making, outperforming state-of-the-art methods.","lang":"eng"}],"publication":"Proceedings of the ACM Web Conference 2026 (WWW ’26)","citation":{"mla":"Das, Pallabee, and Stefan Heindorf. “Discrete Diffusion-Based Model-Level Explanation of Heterogeneous GNNs with Node Features.” <i>Proceedings of the ACM Web Conference 2026 (WWW ’26)</i>, ACM, 2026.","ama":"Das P, Heindorf S.

With the micropolar model, size effects can be considered and the boundary value problem can be regularized when localization effects occur. In order to map the microrotations, an additional strain measure and an additional stress are introduced. For simulation of plasticity, it is possible to define one yield function, and thus one plastic multiplier as well as one equivalent plastic strain occur. This approach is known as the single-surface plasticity approach. The macro- and micro-stresses are coupled in a common flow function. On the other hand, there is the so-called double-surface plasticity when one yield function, one plastic multiplier, and one equivalent plastic strain, respectively, are introduced for each of the macro- and micro-variables. The coupling of the macro- and micro-variables is established by a possible coupling of both yield functions. The purpose of this paper is to compare both approaches and to identify similarities and differences.</jats:p>","lang":"eng"}],"issue":"5","publication":"Archive of Applied Mechanics"},{"intvolume":"       230","date_updated":"2026-04-23T13:00:59Z","author":[{"last_name":"Perniok","first_name":"Daniel","full_name":"Perniok, Daniel","id":"64242"}],"title":"Coxeter-Dynkin algebras of canonical type","status":"public","year":"2026","volume":230,"doi":"10.1016/j.jpaa.2026.108250","user_id":"64242","language":[{"iso":"eng"}],"_id":"63135","abstract":[{"lang":"eng","text":"We propose a definition of Coxeter-Dynkin algebras of canonical type generalising the definition as a path algebra of a quiver.

This shows that our definition gives another representative in the derived equivalence class of the squid algebra, and hence of the corresponding canonical algebra. Finally, we have a closer look at the Grothendieck group and the Euler form which illustrates the connection to Saito's classification of marked extended affine root systems.

Addressing such bottlenecks requires a comprehensive approach to tailoring the precision across operations in the inference computation. To this end, we introduce scaled-integer range analysis (SIRA), a static analysis technique employing interval arithmetic to determine the range, scale, and bias for tensors in quantized neural networks. We show how this information can be exploited to reduce the resource footprint of FPGA dataflow neural network accelerators via tailored bitwidth adaptation for accumulators and downstream operations, aggregation of scales and biases, and conversion of consecutive elementwise operations to thresholding operations. We integrate SIRA-driven optimizations into the open-source FINN framework, then evaluate their effectiveness across a range of quantized neural network workloads and compare implementation alternatives for non-matrix-multiply operations. We demonstrate an average reduction of 17\\% for LUTs, 66\\% for DSPs, and 22\\% for accumulator bitwidths with SIRA optimizations, providing detailed benchmark analysis and analytical models to guide the implementation style for non-matrix layers. Finally, we open-source SIRA to facilitate community exploration of its benefits across various applications and hardware platforms."}],"citation":{"chicago":"Umuroglu, Yaman, Christoph Berganski, Felix Jentzsch, Michal Danilowicz, Tomasz Kryjak, Charalampos Bezaitis, Magnus Sjalander, et al. “SIRA: Scaled-Integer Range Analysis for Optimizing FPGA Dataflow Neural Network Accelerators.” <i>ACM Transactions on Reconfigurable Technology and Systems</i>, n.d. <a href=\"https://doi.org/10.1145/3807510\">https://doi.org/10.1145/3807510</a>.","short":"Y.

Aus der Forschung zu bedingten Wahrscheinlichkeiten und Bayesianischen Aufgaben ist bekannt, dass die Nutzung von Visualisierungen und sogenannten „natürlichen Häufigkeiten“ (z. B. „80 von 100 Personen“) statt Wahrscheinlichkeiten in Prozent Verwechslungen beim Bestimmen von Wahrscheinlichkeiten eindämmen kann. Über den umgekehrten Prozess – das Versprachlichen von in Visualisierungen dargestellten Informationen – ist bisher jedoch wenig bekannt, obwohl diese Versprachlichungen auch für den Aufbau konzeptuellen Wissen als essentiell angesehen werden. In der vorliegenden Studie wurde daher untersucht, wie gut Schüler:innen die Versprachlichung von in Visualisierungen dargestellten Anteilen und natürlichen Häufigkeiten gelingt. Dazu wurde mit 138 Realschüler:innen aus der 9. Jahrgangsstufe ein Papier-und-Bleistift-Test durchgeführt, bei dem den Teilnehmenden nacheinander je ein (vollständig ausgefülltes) Baumdiagramm und ein Netzdiagramm präsentiert wurde. Die Schüler:innen sollten die inhaltliche Bedeutung der in der Visualisierung dargestellten stochastischen Informationen möglichst genau versprachlichen. Fokus der Studie ist der Einfluss der Visualisierung (Baumdiagramm vs. Netzdiagramm) und des Informationsformats der Visualisierung (Anteile in Prozent vs. natürliche Häufigkeiten) auf die richtige Versprachlichung von verschiedenen Relationstypen (Schnittinformationen vs. bedingte Informationen). Die Ergebnisse zeigen unter anderem, dass Informationen in natürlichen Häufigkeiten deutlich besser versprachlicht werden als in Prozenten und dass Schnittinformationen in Prozent besser anhand von Netzdiagrammen als von Baumdiagrammen versprachlicht werden. Die gewonnenen Erkenntnisse geben überdies Einblicke in typische (fehlerhafte) Versprachlichungen von Schüler:innen und könnten als Basis für die Entwicklung eines sprachsensiblen Unterrichts zu Anteilen und Wahrscheinlichkeiten im schulischen Stochastikunterricht dienen.</jats:p>","lang":"eng"}],"date_created":"2026-04-29T08:25:18Z","file":[{"creator":"binder","date_created":"2026-04-29T08:28:25Z","relation":"main_file","date_updated":"2026-04-29T08:28:25Z","file_name":"Rößner Binder Albrecht 2026 Versprachlichung von Anteilen und natürlichen Häufigkeiten anhand von Baum- und Netzdiagrammen.pdf","access_level":"closed","file_size":2993685,"file_id":"65514","success":1,"content_type":"application/pdf"}],"department":[{"_id":"983"}],"type":"journal_article","status":"public","has_accepted_license":"1","publisher":"Springer Science and Business Media LLC","_id":"65512","volume":47,"ddc":["370"],"user_id":"83381","citation":{"ieee":"M.

The resulting prediction framework uses decision tree ensemble models combined with certain model knowledge to forecast different control strategies. This method was chosen due to its best performance in various test scenarios. Very high accuracy and fidelity were achieved for standard control methods like fixed-time, time-of-day-based and 'ordinary' traffic-based programs. Only for the more sophisticated model predictive control which was tested lower accuracies were achieved.\r\nFor the upcoming GLOSA application the penetration of equipped vehicles was varied for different traffic scenarios and control strategies. Results showcase high potentials for enhancing urban mobility and reducing environmental impact by lower emissions and waiting times. However, it is also clear from the studies presented in this contribution that the coordination of the control strategy with the GLOSA vehicles is of enormous importance.","lang":"eng"}],"publication":"2025 IEEE 28th International Conference on Intelligent Transportation Systems (ITSC)","main_file_link":[{"url":"https://doi.org/10.1109/ITSC60802.2025.11423716"}],"language":[{"iso":"eng"}],"date_updated":"2026-04-29T08:51:57Z","publication_status":"published","intvolume":"        28","year":"2026","title":"ML-based Prediction Framework for varying Traffic Signal Control Strategies and its GLOSA-application","author":[{"first_name":"Kevin","orcid":"0000-0003-1183-4679","last_name":"Malena","full_name":"Malena, Kevin","id":"36303"},{"id":"38249","last_name":"Link","first_name":"Christopher","full_name":"Link, Christopher"},{"full_name":"Gausemeier, Sandra","first_name":"Sandra","last_name":"Gausemeier","id":"17793"},{"id":"552","full_name":"Trächtler, Ansgar","last_name":"Trächtler","first_name":"Ansgar"}],"publication_identifier":{"eisbn":["979-8-3315-2418-0"]},"quality_controlled":"1","citation":{"mla":"Malena, Kevin, et al. “ML-Based Prediction Framework for Varying Traffic Signal Control Strategies and Its GLOSA-Application.” <i>2025 IEEE 28th International Conference on Intelligent Transportation Systems (ITSC)</i>, vol. 28, IEEE, 2026.","apa":"Malena, K., Link, C., Gausemeier, S., &#38; Trächtler, A.

The high investment and time required for LPBF development also discourage adoption. This study aims to address these concerns by developing a parameter set for a relevant material using a systematic approach to optimize the density of the printed parts with reduced experimental effort.</jats:p>\r\n                  </jats:sec>\r\n                  <jats:sec>\r\n                    <jats:title>Design/methodology/approach</jats:title>\r\n                    <jats:p>First, an industry-relevant Ni-based superalloy, UNS N09946, was gas-atomized to produce a powder. The powder was fully characterized to ensure successful printing. Next, a processing parameter set tailored for achieving full density was developed for UNS N09946 using a Design of Experiments (DoE) approach based on the volumetric energy density equation.</jats:p>\r\n                  </jats:sec>\r\n                  <jats:sec>\r\n                    <jats:title>Findings</jats:title>\r\n                    <jats:p>A model was created using Response Surface Methodology that relates laser power, scan speed and hatch distance to efficiently identify successful parameter combinations, thus reducing the number of specimens necessary for the successful manufacturing of UNS N09946 using LPBF. A part density of 99.9% was achieved using this method.</jats:p>\r\n                  </jats:sec>\r\n                  <jats:sec>\r\n                    <jats:title>Originality/value</jats:title>\r\n                    <jats:p>This study applies an existing experimental design method to a never-before-printed material.
