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."}],"publication":"ACM Transactions on Reconfigurable Technology and Systems","type":"journal_article"},{"related_material":{"link":[{"description":"Info","relation":"other","url":"https://brill.com/display/title/74830"}]},"publication_status":"inpress","publication_identifier":{"eisbn":["978-3-8467-7106-8"],"isbn":["978-3-7705-7106-2"]},"citation":{"bibtex":"@book{Hannebohm, place={Paderborn}, title={Nach 1984: Biopoethik des eugenetischen Romans}, publisher={Brill | Fink}, author={Hannebohm, Ronja} }","mla":"Hannebohm, Ronja. <i>Nach 1984: Biopoethik des eugenetischen Romans</i>.

Students’ risk literacy is part of the interdisciplinary research project siMINT (Understanding complex STEM topics: Using simulations to promote competences for the 21st century). One first challenge in this project was to find a common ground for the inconsistently conceptualised terms of risk and risk literacy. Consequently, the aim of this paper is to contribute to the conceptualisation of risk and risk literacy. The first part of this paper provides a literature review on these areas, resulting in a working conceptualisation of the two concepts. We further carried out two consecutive steps of a Delphi study with\r\n                    <jats:italic>N</jats:italic>\r\n                     = 15 and\r\n                    <jats:italic>N</jats:italic>\r\n                     = 12 experts respectively, to develop a common conceptualisation based on the plurality of different dimensions and elements of risk and risk literacy. Based on the results of the first step of the Delphi study, we modified our working conceptualisation, using a common model of risk and risk literacy with different dimensions. In the second step of the Delphi study, the experts comment on (i) the dimensions and (ii) the elements of risk and risk literacy in these dimensions. The results showed that the experts are able to locate their individual definitions of risk in the model with three dimensions (relation between risk/uncertainty, connotation, and mathematical object) that we developed and to formulate reasons for their allocation. Furthermore, the results revealed that risk literacy consists of subsets of mathematical and non-mathematical elements that the experts rate differently with regard to their importance. In general, the results contribute to clarifying the constructs of risk and risk literacy as a basis for developing approaches to improve risk literacy.\r\n                  </jats:p>","lang":"eng"}],"file":[{"content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2026-04-20T16:20:33Z","creator":"binder","date_created":"2026-04-20T16:20:33Z","file_size":2030179,"file_id":"65468","access_level":"closed","file_name":"Eichler Büchter Binder 2026 Conceptualising Risk and Risk Literacy - results of a Delphi Study.pdf"}],"publication":"Journal für Mathematik-Didaktik","doi":"10.1007/s13138-026-00268-0","date_updated":"2026-04-20T16:21:27Z","author":[{"last_name":"Eichler","full_name":"Eichler, Andreas","first_name":"Andreas"},{"full_name":"Büchter, Theresa","last_name":"Büchter","first_name":"Theresa"},{"last_name":"Binder","id":"83381","full_name":"Binder, Karin","first_name":"Karin"}],"volume":47,"citation":{"short":"A.

In the theoretical part of the paper, we shed light on this contradiction by consulting general literature on meta-analyses. Ranking the 50 included FC studies by the number of classes per experimental condition, we found a negative correlation between the “size” of a study and the effect in favor of FC. In the empirical part, we present an FC study with three conditions concerning mathematical teaching, based on\r\n                    <jats:italic>n</jats:italic>\r\n                     = 950 students aged 11–13, in which many relevant covariates (e.g., quality of instruction) were addressed.

Nearly two decades ago, the service system concept was introduced as a foundational abstraction in service research, drawing on ideas from the service-dominant logic (S-D logic) of marketing. Despite its widespread adoption in service research, particularly in the IS discipline, the service system concept lacks a solid theoretical foundation. This has resulted in conceptual ambiguity and overlap with related constructs, such as service ecosystems. Moreover, it has largely remained a static analytical lens, insufficiently capturing dynamic service phenomena, including value co-creation and co-destruction, as well as the emergence of institutional arrangements. To address these limitations, we propose Luhmann’s systems theory (LST) as a robust framework for conceptualizing service systems as autopoietic (self-creating) systems, in which communication serves as the fundamental mechanism that drives value co-creation. We derive five theoretical propositions from this re-conceptualization that clarify conceptual ambiguity and allow researchers to explore dynamic service phenomena in greater depth. Given LST’s general approach, our conceptualization provides a theoretically grounded, interdisciplinary foundation for advancing service research."}],"file":[{"access_level":"closed","file_name":"Service is Communication - EM Paper.pdf","file_id":"65477","file_size":2793039,"date_created":"2026-04-21T13:14:30Z","creator":"dabe","date_updated":"2026-04-21T13:14:30Z","relation":"main_file","success":1,"content_type":"application/pdf"}],"publication":"Electronic Markets","title":"Service through communication—Conceptualizing service systems with Luhmann’s systems theory","publisher":"Springer Science and Business Media LLC","date_created":"2026-04-21T13:13:02Z","year":"2026","quality_controlled":"1","issue":"1","article_type":"original","article_number":"37","file_date_updated":"2026-04-21T13:14:30Z","project":[{"_id":"1250","name":"SHAPE : Gestaltung von Dienstleistungsentwicklungsprozessen und lnnovationspartnerschaften mit Unternehmen"}],"_id":"65476","user_id":"59677","department":[{"_id":"195"},{"_id":"534"}],"status":"public","type":"journal_article","main_file_link":[{"open_access":"1","url":"https://link.springer.com/content/pdf/10.1007/s12525-026-00889-w.pdf"}],"doi":"10.1007/s12525-026-00889-w","oa":"1","date_updated":"2026-04-21T13:18:35Z","author":[{"full_name":"Beverungen, Daniel","last_name":"Beverungen","first_name":"Daniel"},{"full_name":"Poeppelbuss, Jens","last_name":"Poeppelbuss","first_name":"Jens"},{"last_name":"Hemmrich","full_name":"Hemmrich, Simon","first_name":"Simon"},{"first_name":"Taskeen","last_name":"Iqbal","full_name":"Iqbal, Taskeen"}],"volume":36,"citation":{"mla":"Beverungen, Daniel, et al. “Service through Communication—Conceptualizing Service Systems with Luhmann’s Systems Theory.” <i>Electronic Markets</i>, vol. 36, no. 1, 37, Springer Science and Business Media LLC, 2026, doi:<a href=\"https://doi.org/10.1007/s12525-026-00889-w\">10.1007/s12525-026-00889-w</a>.","bibtex":"@article{Beverungen_Poeppelbuss_Hemmrich_Iqbal_2026, title={Service through communication—Conceptualizing service systems with Luhmann’s systems theory}, volume={36}, DOI={<a href=\"https://doi.org/10.1007/s12525-026-00889-w\">10.1007/s12525-026-00889-w</a>}, number={137}, journal={Electronic Markets}, publisher={Springer Science and Business Media LLC}, author={Beverungen, Daniel and Poeppelbuss, Jens and Hemmrich, Simon and Iqbal, Taskeen}, year={2026} }","short":"D.

Reuleaux triangle shaped clinched joints, in particular, show pronounced in-plane anisotropy depending on their orientation. While such effects have been studied at joint and specimen scale, their relevance at the structural level remains largely unexplored. In this work, the influence of joint orientation on the bending response of a joined structure is investigated using numerical simulations. A simplified joint replacement model based on the *CONSTRAINED_SPR2 point-connector formulation in LS-DYNA is employed, with parameters calibrated from previously obtained experimental force displacement data. A hat shaped profile structure subjected to three-point bending is analyzed in a parametric study considering variations in joint orientation, joint spacing, and profile geometry. The results show that joint orientation has little influence during the initial deformation phase but becomes increasingly significant at larger displacements, where joint behavior governs load transfer. Orientation dependent effects are found to influence the global force displacement response and local load redistribution among joints, with magnitudes comparable to those induced by changes in joint spacing and structural geometry. The findings confirm that joint orientation effects remain relevant at the structural level and should be considered in the design of structures assembled using non-rotationally symmetric clinched joints.</jats:p>","lang":"eng"}],"department":[{"_id":"149"},{"_id":"321"},{"_id":"9"}],"user_id":"76837","_id":"65483","project":[{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"},{"name":"TRR 285 - Subproject B01","_id":"140"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"language":[{"iso":"eng"}]},{"status":"public","abstract":[{"lang":"eng","text":"<jats:p>Die Bonner Ethik-Erklärung/Über Künstliche Intelligenzen, Bildung und Subjektwerdung/Tagungsberichte</jats:p>"}],"publication":"ZSE (Zeitschrift für Soziologie der Erziehung und Sozialisation)","type":"journal_article","language":[{"iso":"ger"}],"user_id":"107378","_id":"65480","intvolume":"        46","page":"114-117","citation":{"ieee":"A.

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>"}],"status":"public"},{"type":"conference","publication":"Proceedings of the ACM Web Conference 2026 (WWW ’26)","abstract":[{"lang":"eng","text":"Many real-world datasets, such as citation networks, social networks, and molecular structures, are naturally represented as heterogeneous graphs, where nodes belong to different types and have additional features. 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."}],"status":"public","_id":"63918","external_id":{"arxiv":["2508.08458"]},"user_id":"11871","department":[{"_id":"760"}],"language":[{"iso":"eng"}],"year":"2026","citation":{"short":"P.
