@inproceedings{66687, abstract = {{With a range of consumer devices available, augmented reality (AR) continues to make its way into everyday life and is also increasingly used in professional and sensitive contexts. 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.}}, author = {{Krings, Sarah Claudia and Yigitbas, Enes and Sauer, Stefan}}, booktitle = {{Blending Experiences in Interaction Design}}, editor = {{Maciel, Cristiano and Spano, Davide Lucio and Ardito, Carmelo and Freire, André and Prates, Raquel}}, isbn = {{978-3-032-22934-2}}, pages = {{253–276}}, publisher = {{Springer Nature Switzerland}}, title = {{{Perspectives on Privacy and Security in Collaborative AR - Insights from a Scoping Review and an Expert Interview Study}}}, year = {{2026}}, } @proceedings{66704, editor = {{Gräßler, Iris}}, location = {{Paderborn}}, publisher = {{Universitätsbibliothek}}, title = {{{1st International Symposium : March 24 – 26, 2026, Heinz Nixdorf Institute, Paderborn University}}}, doi = {{10.17619/UNIPB/1-2663}}, year = {{2026}}, } @article{66688, author = {{Wüppelmann, Dennis and Yigitbas, Enes}}, issn = {{2944-7682}}, journal = {{GI - Software Engineering }}, publisher = {{Gesellschaft für Informatik, Bonn}}, title = {{{SecCityVR: Visualization and Collaborative Exploration of Software Vulnerabilities in Virtual Reality}}}, doi = {{10.18420/se2026_53}}, year = {{2026}}, } @article{65456, author = {{Fuchs, Christian}}, issn = {{1933-1681}}, journal = {{Journal of Information Technology & Politics }}, pages = {{1--21}}, title = {{{What is Digital Democracy?}}}, doi = {{10.1080/19331681.2026.2660162}}, year = {{2026}}, } @article{66707, abstract = {{This article examines the most frequently attributed statement of Jesus in the Qur’an, namely, ‘God is my Lord and your Lord’ (Q 19:36; Q 43:64; Q 3:51; Q 5:72; Q 5:117).

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.}}, author = {{Dübbert, Alexander}}, booktitle = {{Ökologische Diskurse heute.

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. 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. 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.}}, author = {{Kiermaier, Michael and Klawuhn, Lukas-André Dominik}}, title = {{{Intersection numbers for designs in regular semilattices}}}, year = {{2026}}, } @article{66741, abstract = {{Abstract We study theoretically how high-gain effects affect the measurement outcome of visible signal spectra in undetected photon measurement schemes. We consider two interferometric configurations: firstly, the SU(1,1) interferometer where the idler incurs loss and additional dispersion in between two identical, lossless, squeezers; secondly, the induced coherence interferometer where the idler incurs loss and additional dispersion in between two identical, lossless, squeezers and where the second squeezer is seeded by the idler and a vacuum ancilla mode. Furthermore, we consider a distributed loss configuration where the idler incurs loss as it propagates in the nonlinear medium. Motivated by experimental evidence and due to the fact that broadband sources are ideal for these measurement schemes, we use the dispersive data of a third-order dispersion engineered integrated waveguide parametric down conversion (PDC) source presented in Roeder et al (2024 New J. Phys. 26 123025) to model the PDC spectra in the three configurations. For each configuration we consider the case of idler-only (i) absorption, (ii) additional dispersion, and (iii) the combined effects. We obtain results which outline the strength and weaknesses of the different configurations at different operation points. }}, author = {{Houde, Martin and Roeder, Franz and Silberhorn, Christine and Brecht, Benjamin and Quesada, Nicolás}}, issn = {{1367-2630}}, journal = {{New Journal of Physics}}, number = {{7}}, publisher = {{IOP Publishing}}, title = {{{High-gain effects in broadband continuous-wave parametric down conversion sources and measurements with undetected photons}}}, doi = {{10.1088/1367-2630/ae8692}}, volume = {{28}}, year = {{2026}}, } @article{66740, abstract = {{Abstract We theoretically compare the quantum Fisher information (QFI) for three configurations of absorption spectroscopy with undetected idler photons: an SU(1,1) interferometer with inter-source idler loss, an induced-coherence (IC) setup in which the idler partially seeds a second squeezer together with a vacuum ancilla, and a distributed-loss (DL) scheme with in-medium attenuation. We calculate the QFI as a function of parametric gain for both full and signal-only detection access. For losses below 99% and low to moderate gain, the SU(1,1) configuration provides the largest QFI. At high gain and intermediate loss, the IC scheme performs best, while under extreme attenuation (transmission < 1%) the DL model becomes optimal.
