This paper aims to review the development of AR since 2010, particularly in technical university laboratories, through a systematic literature review. The study investigates AR's relevance in university teaching and examines specific AR applications in laboratory settings. Using a mixed-method approach, the research first employs a web crawler to gather 27,249 articles from the Lens database, followed by a bibliometric analysis. Further, Google Scholar is used to find 374 articles related to AR in scientific and technical laboratories, with 51 significant ones evaluated for application areas, findings, and other criteria. The findings show that AR in education is a growing trend, with a significant increase in publications and citations in recent years. Most studies focus on marker-based mobile AR applications, assessing aspects like motivation and user experience through surveys and interviews. However, there's limited research on AR's learning effectiveness in laboratories, partly due to the scarcity of technical equipment. One study found no significant learning impact from AR.}}, author = {{Alptekin, Mesut and Froese, Lennart and Temmen, Katrin}}, booktitle = {{Recent Trends of AI Technologies and Virtual Reality: Proceedings of 8th International Conference on Artificial Intelligence and Virtual Reality (AIVR 2024)}}, keywords = {{Augmented Reality, Mixed Reality, Literature Review, Bibliometric Analysis, Education \and Laboratories}}, location = {{Fukuoka, Japan}}, pages = {{427}}, publisher = {{Springer Nature}}, title = {{{Quantitative and Qualitative Literature Review of Augmented Reality in Teaching}}}, volume = {{432}}, year = {{2025}}, } @inproceedings{61047, author = {{Rautenberg, Frederik and Seebauer, Fritz and Wiechmann, Jana and Kuhlmann, Michael and Wagner, Petra and Haeb-Umbach, Reinhold}}, booktitle = {{Interspeech 2025}}, location = {{Rotterdam}}, publisher = {{ISCA}}, title = {{{Synthesizing Speech with Selected Perceptual Voice Qualities – A Case Study with Creaky Voice}}}, doi = {{10.21437/Interspeech.2025-1443}}, year = {{2025}}, } @article{61140, author = {{Nicolai, Marcel and Bulling, Jannis and Narayanan, M.M. and Zeipert, Henning and Prager, Jens and Henning, Bernd}}, issn = {{0041-624X}}, journal = {{Ultrasonics}}, publisher = {{Elsevier BV}}, title = {{{Dynamic interface behavior in coupled plates: Investigating Lamb wave mode repulsion with a spring-based model}}}, doi = {{10.1016/j.ultras.2025.107799}}, volume = {{158}}, year = {{2025}}, } @inproceedings{61396, author = {{Nölle, Florian and Schmid, Hans-Joachim and Bentrup, Leon Alexander and Temmen, Katrin}}, booktitle = {{MINT-Symposium}}, location = {{Nürnberg}}, title = {{{Erfolgreich Studieren - sinnvolle Lernstrategien erlernen (Posterbeitrag)}}}, year = {{2025}}, } @article{60891, abstract = {{Straight dielectric waveguide channels made from slabs of thin-film lithium niobate (TFLN), or lithium niobate on insulator (LNOI), are investigated in the linear regime, for channels of rib and strip type with common trapezoidal cross sections, in Z-cut and X-cut samples at varying on-chip orientation. We clarify the theoretical basis for the waveguides with potentially non-diagonal core permittivity. Symmetry classes can be distinguished that differ in their consequences for potential modal degeneracy and polarization conversion. Our rigorous numerical analysis by means of a finite-element solver takes the anisotropy of the lithium niobate cores rigorously into account. We discuss extensive data for effective indices, polarization properties, and hybridization of guided modes, in single- and multimode channels. Scans over the waveguide width and orientation as primary parameters are complemented by a series of illustrations of vectorial mode profiles. These turn out to be essentially complex in cases of X-cut channels at non-crystal-axis-aligned orientations.}}, author = {{Hammer, Manfred and Khan, Shahriar and Taheri, Behnood and Farheen, Henna and Förstner, Jens}}, issn = {{2770-0208}}, journal = {{Optics Continuum}}, keywords = {{tet_topic_waveguide}}, number = {{10}}, pages = {{2356}}, publisher = {{Optica Publishing Group}}, title = {{{TFLN channel waveguides of rib and strip type: Properties of guided modes}}}, doi = {{10.1364/optcon.569959}}, volume = {{4}}, year = {{2025}}, } @inproceedings{61760, abstract = {{We present a topology-optimized silicon nitride (Si3N4) coupler designed to enhance the coupling efficiency between integrated single-photon emitters and photonic waveguide modes.

Dieses besteht aus einer quantitativen Studie (n=115), angelehnt an das TPACK-Modell, und einer anschließenden qualitativen Inter-viewstudie (n=18) angelehnt an das PCK-Modell. Es zeigt sich, dass akademische Selbstkonzepte angehender Lehrkräfte anhand von Professionswissensmodellen strukturierbar sind. Dies trifft sowohl auf die Strukturierung anhand des TPACK-Modells als auch anhand des PCK-Modells zu. Als Entwicklungseinflüsse zeigen sich besonders Aspekte: praktische Erfahrungen im schulischen sowie im fachwissenschaftlichen Bereich und auch die Auswirkungen sozialer und dimensionaler Vergleichsprozesse. Bei den Auswirkungen von Vergleichsprozessen fungiert jedoch die wahr-genommene Relevanz der jeweiligen Dimensionen der akademischen Selbstkonzepte als Mode-rator.
