Here, we demonstrate a hybrid nonlinear optoelectronic device that enhances the detection efficiency of a (001)-oriented GaAs PIN photodiode under telecommunication-wavelength illumination, where absorption is intrinsically limited to two-photon absorption (2PA). Our approach relies on the integration of a transferred, nanopatterned 385 nm-thick (111)-oriented GaAs nanofilm acting as an on-chip nonlinear frequency-conversion layer. Elliptical GaAs nanoresonators are employed to enhance second-harmonic generation (SHG) resonantly, converting incident 1550 nm radiation into above-bandgap photons efficiently absorbed by the underlying diode. Spatially resolved current–voltage measurements reveal a pronounced enhancement of the detector response in regions covered by the nanoantennas. The device exhibits a low dark current, while the metasurface-covered regions show the largest current response under 1560 nm excitation compared to the bare GaAs(100) diode and the unstructured GaAs(111) film.

When multiple loading components (e.g., tension, compression, shear) act simultaneously but not in temporal synchrony, out‑of‑phase mixed‑mode conditions occur. Such loadings are typical for automotive chassis parts and mechanically joined sheet‑metal assemblies. For optimized design of structural components, the crack kinking angle that occurs under mixed‑mode loading must be predicted as accurately as possible. At present, however, this is still challenging for out‑of‑phase loading conditions. To investigate the associated crack kinking behavior, a novel Compact‑Tension‑Shear‑Mini (CTSM) specimen was developed, enabling controlled generation of plane out-of-phase mixed-mode loading states. Experiments were performed under various combinations of cyclic and static mode I and mode II load components and compared with the analytical predictions of the Out-of-Phase Mixed-Mode (OMM) concept. The measured crack kinking angles showed very good agreement with the predicted values, with mean deviations of only a few degrees, demonstrating the validity and reproducibility of the approach. These findings confirm the applicability of the OMM concept for describing fatigue‑crack propagation under non‑proportional mixed‑mode loading and provide a basis for fatigue‑life assessment of clinched joints and other cyclic multi-axially loaded components.</jats:p>","lang":"eng"}],"issue":"1","publication":"Discover Mechanical Engineering","doi":"10.1007/s44245-026-00236-5","language":[{"iso":"eng"}],"article_number":"113","intvolume":"         5","date_updated":"2026-08-06T10:07:30Z","publication_status":"published","publication_identifier":{"issn":["2731-6564"]},"author":[{"id":"57245","full_name":"Krome, Sven","last_name":"Krome","first_name":"Sven"},{"id":"291","full_name":"Kullmer, Gunter","last_name":"Kullmer","first_name":"Gunter"},{"last_name":"Weiß","first_name":"Deborah","full_name":"Weiß, Deborah"},{"first_name":"Tobias","last_name":"Duffe","full_name":"Duffe, Tobias"},{"orcid":"0000-0003-2147-8444","first_name":"Richard","last_name":"Ostwald","full_name":"Ostwald, Richard","id":"106876"}],"title":"Experimental determination of kinking angles with out-of-phase mixed-mode loading by means of a novel specimen geometry","year":"2026","project":[{"name":"TRR 285 - Project Area B","_id":"132"},{"name":"TRR 285 - Subproject B04","_id":"143"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"citation":{"mla":"Krome, Sven, et al. “Experimental Determination of Kinking Angles with Out-of-Phase Mixed-Mode Loading by Means of a Novel Specimen Geometry.” <i>Discover Mechanical Engineering</i>, vol. 5, no. 1, 113, Springer Science and Business Media LLC, 2026, doi:<a href=\"https://doi.org/10.1007/s44245-026-00236-5\">10.1007/s44245-026-00236-5</a>.","bibtex":"@article{Krome_Kullmer_Weiß_Duffe_Ostwald_2026, title={Experimental determination of kinking angles with out-of-phase mixed-mode loading by means of a novel specimen geometry}, volume={5}, DOI={<a href=\"https://doi.org/10.1007/s44245-026-00236-5\">10.1007/s44245-026-00236-5</a>}, number={1113}, journal={Discover Mechanical Engineering}, publisher={Springer Science and Business Media LLC}, author={Krome, Sven and Kullmer, Gunter and Weiß, Deborah and Duffe, Tobias and Ostwald, Richard}, year={2026} }","ama":"Krome S, Kullmer G, Weiß D, Duffe T, Ostwald R.

Clinching allows different materials to be joined together. A key task in this context is to perform crack growth simulations in the vicinity of clinched joints considering different load and environmental conditions. This requires formulaic descriptions of the fatigue crack growth rate curves for the materials used. For this purpose, fatigue crack growth rate curves for different R-ratios and temperatures are determined experimentally. Generally, these fatigue crack growth rate curves can be described very well using a novel two-part exponential approach for the formulaic description of fatigue crack growth rate curves developed at Applied Mechanics of Paderborn University (FAM). In this case, three parameters are sufficient to describe the fatigue crack growth rate curves. For the material HCT590X, which is frequently used in clinched joints, it is shown as an example how the parameters vary with the R-ratio and the temperature. In addition, at high crack growth rates, a significant rise in the fatigue crack growth rate curve sometimes occurs at both low and high temperatures. To account for this feature, the two-part exponential approach can be expanded to include a third part.</jats:p>"}],"date_created":"2026-08-06T10:14:38Z","type":"journal_article","department":[{"_id":"9"},{"_id":"952"},{"_id":"321"}],"title":"Influence of the R-Ratio and the Temperature on the Coefficients of a Novel Exponential Approach for the Formulaic Description of Fatigue Crack Growth Rate Curves","year":"2026","author":[{"full_name":"Kullmer, Gunter","first_name":"Gunter","last_name":"Kullmer","id":"291"},{"last_name":"Krome","first_name":"Sven","full_name":"Krome, Sven","id":"57245"},{"id":"45673","full_name":"Weiß, Deborah","first_name":"Deborah","last_name":"Weiß"},{"id":"4668","full_name":"Schramm, Britta","first_name":"Britta","last_name":"Schramm"},{"first_name":"Richard","last_name":"Ostwald","orcid":"0000-0003-2147-8444","full_name":"Ostwald, Richard","id":"106876"}],"publication_identifier":{"issn":["2075-4701"]},"publication_status":"published","date_updated":"2026-08-06T10:17:54Z","intvolume":"        16","article_number":"835","language":[{"iso":"eng"}],"doi":"10.3390/met16080835","citation":{"chicago":"Kullmer, Gunter, Sven Krome, Deborah Weiß, Britta Schramm, and Richard Ostwald. “Influence of the R-Ratio and the Temperature on the Coefficients of a Novel Exponential Approach for the Formulaic Description of Fatigue Crack Growth Rate Curves.” <i>Metals</i> 16, no. 8 (2026). <a href=\"https://doi.org/10.3390/met16080835\">https://doi.org/10.3390/met16080835</a>.","short":"G.

Existing approaches do not offer sufficient support for harnessing technical tacit knowledge regarding sustainable product engineering. In this paper a three-step method is presented: The method contains knowledge acquisition, requirements extraction und requirements validation for quality assurance. Acquisition is performed by support artifacts like interview guidelines. Extraction is supported by Artificial Intelligence, converting statements into requirements. These requirements are validated using a specific questionnaire. The developed approach is applied in a funded project of the European Union (EU) with automotive industry partners. The method supports product engineers to collect tacit knowledge from experienced employees, transform unsystematic knowledge into standardized technical requirements and validate them. Application of this method enables creation of validated requirements that can be applied throughout the company and are not exclusively dependent on a single employee.","lang":"eng"}],"date_created":"2026-07-20T13:16:49Z","department":[{"_id":"152"}],"type":"conference","keyword":["Tacit knowledge","Sustainability","Product Engineering","Artificial Intelligence"],"conference":{"name":"International Symposium on Hybrid Intelligence in Product and Production Engineering 1. 2026 Paderborn","start_date":"2026-03-24","location":"Paderborn","end_date":"2026-03-26"},"status":"public","publisher":"Universitätsbibliothek","_id":"66547","page":"229-238","editor":[{"last_name":"Graessler","first_name":"Iris","full_name":"Graessler, Iris"}],"volume":1,"user_id":"98210","citation":{"apa":"Mansheim, J., Gräßler, I., &#38; Pfeifer, J.

A substantial share of a product’s environmental performance is determined during engineering. Early assessments rely on generic data, which is gradually replaced by more concrete simulation and primary data as product maturity increases. The effective use of engineering simulation models for Life Cycle Assessment (LCA) therefore remains a central challenge under heterogeneous, distributed and rapidly evolving data. This article presents a systematic review of product engineering approaches for integrating simulation models into LCA. A seven-step research approach is applied to identify, categorize and evaluate existing approaches across CAx tools. Relevant simulation parameters for sustainability assessment, including material properties, process descriptors, consumables and waste streams, are identified and analyzed. Based on identified data characteristics, the potential of Data Science and Artificial Intelligence methods for LCA data preparation is assessed. A conceptual knowledge-graph-based decision support approach is derived to enable structured integration, traceability and reuse of simulation data for sustainability assessment. The approach is evaluated using criteria from literature. Structured integration of simulation data improves early-stage data quality and supports decision-making in sustainable product engineering.","lang":"eng"}],"publication":"1st International Symposium: March 24 – 26, 2026, Heinz Nixdorf Institute, Paderborn University","department":[{"_id":"152"}],"type":"conference","date_created":"2026-07-16T09:41:28Z","conference":{"location":"Paderborn","name":"International Symposium on Hybrid Intelligence in Product and Production Engineering 1. 2026 Paderborn","start_date":"20260324","end_date":"20260326"},"status":"public","editor":[{"last_name":"Gräßler","first_name":"Iris","full_name":"Gräßler, Iris"}],"user_id":"67999","_id":"66514","publisher":"Universitätsbibliothek","quality_controlled":"1","citation":{"ieee":"I.

The intention of reassembling products and their part simplies that inspection and sorting need to be integrated with value-conserving objectives. Further, disassembly and reassembly require higher competence levels of workforce than assembly. To provide the required information during engineering, a metadata model (MDM) is required that links established product models to capability models. Since processes to be carried out for realizing a product largely determine required employees’ capabilities, the proposed approach uses the ADR process domain to connect product and capability domains. The research is based on a systematic literature analysis to identify existing approaches regarding MDMs of ADR processes. Based on the results, an integrative MDM is developed that answers defined competence questions. The model enables queries which support engineers by feedback on which skills are required for a product. This builds up a basis to check whether required skills are available in the manufacturing company, either early in product engineering or later in ADR planning."}],"publication":"1st International Symposium on Hybrid Intelligence in Product and Production Engineering","doi":"10.17619/UNIPB/1-2640","main_file_link":[{"open_access":"1"}],"language":[{"iso":"eng"}],"date_updated":"2026-08-13T08:14:20Z","publication_status":"published","year":"2026","title":"Enabling extreme data by using DS/AI approaches","author":[{"id":"47565","last_name":"Gräßler","first_name":"I.","orcid":"0000-0001-5765-971X","full_name":"Gräßler, I."},{"last_name":"Hesse","first_name":"Thomas","full_name":"Hesse, Thomas","id":"76202"},{"full_name":"Pottebaum, Jens","orcid":"http://orcid.org/0000-0001-8778-2989","first_name":"Jens","last_name":"Pottebaum","id":"405"}],"oa":"1","place":"Paderborn","quality_controlled":"1","citation":{"ieee":"I.

Especially collaborative use cases, such as remote meetings or maintenance, offer potential, but also move issues in the area of privacy and security into focus. We conducted a scoping review to gain an overview of the current situation and found a lack of clear standards, with most approaches focusing on single protection features. Using the knowledge from the scoping review, we set up and conducted expert interviews. They revealed that end-users are almost completely dependent on developers or device manufacturers regarding their options for protection. The interviews also showed that most developers put little focus on privacy and security, often due to external constraints, such as employers treating the topic as an “afterthought” and not budgeting enough time for it. The experts suggested offering better software support to developers to enable the inclusion of privacy and security with less overhead as a solution. It was also suggested that a general rise in privacy and security awareness could improve the overall situation.","lang":"eng"}],"page":"253–276","_id":"66687","publisher":"Springer Nature Switzerland","language":[{"iso":"eng"}],"user_id":"8447","editor":[{"last_name":"Maciel","first_name":"Cristiano","full_name":"Maciel, Cristiano"},{"last_name":"Spano","first_name":"Davide Lucio","full_name":"Spano, Davide Lucio"},{"full_name":"Ardito, Carmelo","last_name":"Ardito","first_name":"Carmelo"},{"last_name":"Freire","first_name":"André","full_name":"Freire, André"},{"first_name":"Raquel","last_name":"Prates","full_name":"Prates, Raquel"}],"title":"Perspectives on Privacy and Security in Collaborative AR - Insights from a Scoping Review and an Expert Interview Study","status":"public","year":"2026","publication_identifier":{"isbn":["978-3-032-22934-2"]},"author":[{"first_name":"Sarah Claudia","last_name":"Krings","orcid":"0000-0001-8040-7553","full_name":"Krings, Sarah Claudia","id":"64063"},{"id":"8447","full_name":"Yigitbas, Enes","first_name":"Enes","last_name":"Yigitbas","orcid":"0000-0002-5967-833X"},{"id":"447","first_name":"Stefan","last_name":"Sauer","orcid":"0000-0003-3084-0409","full_name":"Sauer, Stefan"}],"date_updated":"2026-08-13T09:38:27Z"},{"date_created":"2026-08-13T08:39:46Z","type":"conference_editor","oa":"1","department":[{"_id":"152"}],"citation":{"apa":"Gräßler, I.

The parametric down-conversion (PDC) process utilized in these interferometers is theoretically described via integro-differential equations describing spatial evolution of the plane-wave operators. It is shown that for the phase sensitivity of these interferometers, supersensitivity can be reached provided that proper diffraction compensation is applied. The phase sensitivity improves if the gain is increased or if the number of effective modes is decreased. This comes at the cost of the phase-region width over which supersensitivity can be reached. Based on the Schmidt mode structure of SU(1,1) interferometers, a processing method is constructed which allows for the experimental retrieval of the levels of squeezing and anti-squeezing of the multimode state generated by the first PDC section of an SU(1,1) interferometer. It is then applied experimentally by collaborators and is found to be in good agreement with the theoretical predictions. Finally, SU(1,1) interferometers pumped with Laguerre-Gaussian beams are analyzed in the context of angular displacement measurements. As either the gain, the OAM index or the radial index of the pump are increased, the measurement uncertainty is decreased, ultimately allowing for supersensitive measurements. Generally, the behavior is the same as for the phase sensitivity.","lang":"eng"}]},{"date_created":"2026-07-30T12:07:24Z","keyword":["Berichterstattung","Jahrhunderthochwasser","Kognitive Linguistik","konzeptuelle Metapher","Ökolinguistik","Schematizität"],"type":"book_chapter","department":[{"_id":"115"}],"publication":"Ökologische Diskurse heute.

In journalistic reporting, numerous conceptual metaphors are used to conceptualise such extreme weather events. This linguistic study investigates how the century flood that occurred in southern Germany in late May and early June 2024 was metaphorically conceptualised in nationwide online journalism by identifying patterns of metaphorical conceptualisation. The analysis draws on the foundations of Conceptual Metaphor Theory as proposed by Lakoff and Johnson (1980), refined through the graded distinction of schematicity levels in conceptual structure proposed in Kövecses (2017, 2020, 2022) Extended Conceptual Metaphor Theory. Accordingly, metaphors are understood as schematically distinguishable mappings of conceptual aspects from source to target areas, through which particular actions are constituted. Adopting a mixed-methods approach that integrates manual with (semi-)automatic analytical procedures, the study reveals that the century flood is predominantly conceptualised through the highly schematic metaphor ZEIT IST SUBSTANZ (›time is substance‹), the less schematic metaphor NATURKATASTROPHEN SIND PERSONEN (›natural disasters are persons‹), and a set of least schematic, elaborating metaphors, namely HOCHWASSER IST GEGNER (›flood is an opponent‹), HOCHWASSER IST ZERSTÖRER (›flood is a destroyer‹) and HOCHWASSER IST MÖRDER (›flood is a murderer‹). From an ecolinguistic perspective, the study critically reflects on how these metaphorical conceptualisations obscure human co-responsibility for the intensity of extreme flood events.","lang":"eng"}],"main_file_link":[{"url":"https://www.transcript-verlag.de/978-3-8376-8048-5/oekologische-diskurse-heute/?number=978-3-8394-5910-2","open_access":"1"}],"language":[{"iso":"ger"}],"series_title":"Climates - Cultures - Contexts","doi":"10.14361/9783839459102-171 ","title":"Metaphorische Konzeptualisierungen des Jahrhunderthochwassers in Süddeutschland im Spätfrühling 2024.

While designs in regular semilattices go back to Delsarte, our regularity assumptions are weaker than his and need not give rise to an association scheme. In this framework, we extend Mendelsohn's equations, prove a generalized Singleton bound with Steiner systems as equality cases, and determine the block intersection distribution at any block of a Steiner system. In particular, this distribution is independent of the chosen block.\r\n  Specializing to several classical semilattice families, our results recover a number of well-known distributions in coding and design theory. In the Hamming and the $q$-Hamming (or bilinear forms) schemes, they give the local distance distributions of MDS and MRD codes, respectively. In the Johnson and $q$-Johnson (or Graßmann) schemes, they reproduce the block intersection distribution of classical and $q$-analog Steiner systems, equivalently the distance distribution of diameter-perfect constant-weight codes and diameter-perfect constant-dimension subspace codes. For the $q$-Johnson schemes, to the best of our knowledge, this result is new. As a further illustration, we apply our theory to designs of perfect matchings.\r\n  Our approach provides a unified treatment of these cases in the strongest form known in the literature, determining the distribution relative to each individual block or codeword, without averaging and without linearity or additivity assumptions. Moreover, it identifies the natural double-counting objects underlying these distributions, leading to formulas in the regularity parameters of the semilattice and avoiding the more cumbersome expressions that arise in eigenvalue-based approaches via the ambient association scheme.","lang":"eng"}],"citation":{"ieee":"M.
