Measurement results for the elastic material parameters are acquired non-destructively using ultrasonic transmission measurements of hollow cylindrical polymer specimens. To determine the material parameters, an inverse approach is used comparing measurements with simulated data. Previous studies show that the procedure exhibits low sensitivity with respect to the shear parameters of the material. In order to increase the sensitivity, we propose to apply a spatially annular excitation on the base of the specimen. As a measure to analyse the sensitivities with respect to all parameters and their linear independence, we observe the volume of the parallelotope of the sensitivity vectors. Here, a scaled boundary finite element formulation of wave propagation in the specimen is expanded to yield derivative information directly, and a sensitivity analysis can be carried out efficiently. Finally, the results of this sensitivity analysis with regard to the annular excitation are also applied to the measurement setup.}}, author = {{Dreiling, Dmitrij and Itner, Dominik and Gravenkamp, Hauke and Claes, Leander and Birk, Carolin and Henning, Bernd}}, issn = {{0957-0233}}, journal = {{Measurement Science and Technology}}, keywords = {{Sensitivity analysis, Ultrasonic transducer, Guided waves, Polymers, Gram determinant}}, publisher = {{IOP Publishing}}, title = {{{Increasing the sensitivity of ultrasonic transmission measurements for elastic material parameter estimation}}}, doi = {{10.1088/1361-6501/add9b6}}, volume = {{36}}, year = {{2025}}, } @article{58516, abstract = {{Abstract Academic emotions play a crucial role in mathematics learning, significantly influencing motivation, academic achievement, and career aspirations in mathematics. With the notable increase in research on emotions in recent years, our review uses Pekrun’s control-value theory with two primary objectives: to systematically describe the characteristics of emotions in recent research through a systematic review, and to synthesize evidence on the relationships between specific emotions, control-value antecedents, and mathematics achievement via a meta-analysis. The systematic review of 112 studies revealed that more than 100 specific emotions have been addressed in recent research, which we analyzed based on key emotion characteristics: valence and activation, type of object, temporal stability, and social context. The findings from the systematic review provide an overview of mathematics-specific objects that emotions have referred to in the most recent research. The subsequent meta-analysis demonstrated that mathematics achievement (e.g., test scores and grades) was positively related to enjoyment, hope, and pride ( $$\overline{r}$$ r ¯  = .247, .224, and .344, respectively) but negatively related to anger, boredom, frustration, hopelessness, and shame ( $$\overline{r}$$ r ¯ = − .322, − .187, − .207, − .378, and − .291, respectively).

While censors analyze the Transport Layer Security (TLS) protocol to block encrypted HTTP traffic, censorship circumvention efforts have primarily focused on other protocols such as TCP. In this paper, we hypothesize that the TLS protocol offers previously unseen opportunities for censorship circumvention techniques. We tested our hypothesis by proposing possible censorship circumvention techniques that act on the TLS protocol. To validate the effectiveness of these techniques, we evaluate their acceptance by popular TLS servers and successfully demonstrate that these techniques can circumvent censors in China and Iran. In our evaluations, we discovered 38—partially standard-compliant—distinct censorship circumvention techniques, which we could group into 11 unique categories. Additionally, we provide novel insights into how China censors TLS traffic by presenting evidence of at least three distinct censorship appliances. We suspect that other parts of China’s censorship apparatus and other censors exhibit similar structures and advocate future censorship research to anticipate them. With this work, we hope to aid people affected by censorship and stimulate further research into censorship circumvention using cryptographic protocols.}}, author = {{Niere, Niklas and Lange, Felix and Merget, Robert and Somorovsky, Juraj}}, booktitle = {{2025 IEEE Symposium on Security and Privacy (SP)}}, location = {{San Francisco}}, title = {{{Transport Layer Obscurity: Circumventing SNI Censorship on the TLS-Layer}}}, doi = {{10.1109/SP61157.2025.00151}}, year = {{2025}}, } @article{60102, abstract = {{ Zusammenfassung: Studien haben gezeigt, dass frühe numerische Kompetenzen einen Einfluss auf die spätere mathematische Entwicklung haben. Vor diesem Hintergrund ist es wichtig, die numerischen Kompetenzen bereits im Kindergartenalter zu erfassen, um Kinder, denen wichtige Kompetenzen für die mathematische Entwicklung fehlen, und für die das Risiko der Entwicklung von Rechenschwierigkeiten besteht, frühzeitig und praxistauglich zu identifizieren. In der Studie wird ein Screening zur Erfassung der numerischen Kompetenzen im Kindergartenalter präsentiert, bei dem ausgewählte Aufgaben in einem Gruppensetting durchgeführt werden können. An der Validierung nahmen Kinder im Alter von vier bis sechs Jahren aus der Schweiz ( n = 431) und aus Deutschland ( n = 325) teil. Die Ergebnisse zeigen, dass mit dem Screening in verschiedenen Gruppen (Schweiz, Deutschland) mit wenigen Ausnahmen dieselben Eigenschaften gemessen werden. Die prognostische Validität für den Zeitpunkt kurz vor Schuleintritt ist zufriedenstellend. Der Testwert auf Basis des Gruppensettings lässt sich valide interpretieren, da sich keine Unterschiede zwischen Kindern, die die Aufgaben einzeln gelöst haben und Kindern, die die Aufgaben in Gruppen bearbeitet haben, gezeigt haben. Zusammenfassend lässt sich sagen, dass das Screening durch die Kombination von Einzel- und Kleingruppentests die Erfassung numerischer Fähigkeiten im Kindergarten in kurzer Zeit zuverlässig und valide ermöglicht. }}, author = {{Gloor, Noemi and Kucian, Karin and Bruns, Julia and Gasteiger, Hedwig and Moser Opitz, Elisabeth}}, issn = {{2191-9186}}, journal = {{Frühe Bildung}}, publisher = {{Hogrefe Publishing Group}}, title = {{{Erfassung der numerischen Kompetenzen im Kindergartenalter}}}, doi = {{10.1026/2191-9186/a000699}}, year = {{2025}}, } @article{60081, author = {{Naumann, Marius and Ostermann, Moritz and Buchenau, Nadja and Oetzel, Jannik and Schlosser, Florian and Meschede, Henning and Tröster, Thomas}}, issn = {{0196-8904}}, journal = {{Energy Conversion and Management}}, publisher = {{Elsevier BV}}, title = {{{Energy efficiency improvement for decarbonization in manufacturing industry: A review}}}, doi = {{10.1016/j.enconman.2025.119763}}, volume = {{338}}, year = {{2025}}, } @inbook{60156, author = {{Ködding, Patrick and Jahn, Mathis and Dumitrescu, Roman and Koldewey, Christian}}, booktitle = {{New Digital Work II - Digital Sovereignty of Companies and Organizations}}, editor = {{Schmuntzsch, Ulrike and Shajek, Alexandra and Hartmann, Ernst Andreas}}, isbn = {{9783031699931}}, pages = {{93--108}}, publisher = {{Springer Nature Switzerland}}, title = {{{Challenges for Scenario-Based Foresight and Potential for Digital Technologies: Insights from Practice}}}, doi = {{10.1007/978-3-031-69994-8}}, year = {{2025}}, } @inproceedings{60160, author = {{Förster, Felix and Bausen, Steffen and Bernijazov, Ruslan and Koldewey, Christian and Dumitrescu, Roman and Bursac, Nikola}}, booktitle = {{Stuttgarter Symposium für Produktentwicklung SSP 2025}}, editor = {{Hölzle, Katharina and Kreimeyer, Matthias and Roth, Daniel and Maier, Thomas and Riedel, Oliver}}, location = {{Stuttgart}}, pages = {{102--113}}, publisher = {{Fraunhofer IAO, Stuttgart}}, title = {{{Chances of smart Views: Integration of Stakeholder perspectives using videobased Views in MBSE}}}, doi = {{10.18419/opus-16366}}, year = {{2025}}, } @article{63587, author = {{Suri, Ali}}, journal = {{Differential Geometry and its Applications}}, publisher = {{Elsevier}}, title = {{{Stochastic Euler-Poincaré reduction for central extension}}}, doi = {{https://doi.org/10.1016/j.difgeo.2025.102290}}, volume = {{101}}, year = {{2025}}, } @inproceedings{63589, author = {{Cruzeiro, Ana Bela and Suri, Ali}}, isbn = {{978-3-032-03920-0}}, publisher = {{Springer}}, title = {{{Stochastic Perturbation of Geodesics on the Manifold of Riemannian Metrics}}}, doi = {{https://doi.org/10.1007/978-3-032-03921-7_41}}, year = {{2025}}, } @inproceedings{62300, author = {{Claes, Leander and Hölscher, Jonas and Friesen, Olga and Scheidemann, Claus and Hemsel, Tobias and Henning, Bernd}}, booktitle = {{2025 International Congress on Ultrasonics}}, pages = {{142–145}}, publisher = {{AMA Service GmbH}}, title = {{{Estimation of third order elastic constants of piezoceramics using DC biased impedance measurements}}}, doi = {{10.5162/ultrasonic2025/a18-a6}}, year = {{2025}}, } @inproceedings{62296, author = {{Spieker, Carsten and Förstner, Jens and Hölscher, Jonas and Claes, Leander and Henning, Bernd}}, booktitle = {{2025 International Congress on Ultrasonics}}, pages = {{126–129}}, publisher = {{AMA Service GmbH}}, title = {{{Modeling and simulation of the behavior of piezoceramics with the discontinuous Galerkin method}}}, doi = {{10.5162/ultrasonic2025/a18-a1}}, year = {{2025}}, } @inproceedings{62297, author = {{Hölscher, Jonas and Friesen, Olga and Claes, Leander and Spieker, Carsten and Förstner, Jens and Henning, Bernd}}, booktitle = {{2025 International Congress on Ultrasonics}}, pages = {{130–133}}, publisher = {{AMA Service GmbH}}, title = {{{Multiscale thermo-piezoelectric simulations using the finite element method}}}, doi = {{10.5162/ultrasonic2025/a18-a2}}, year = {{2025}}, }
