Parallel nanogrooves on a substrate, created through 3D nanoprinting in a negative-tone photoresin optimized for two-photon polymerization are used for this purpose. Azimuthal anchoring energies of the order from 10−6 J/m2 to 10−5 J/m2 are found, depending on the spacing, width and depth of the grooves. In part, these values are larger than those reported previously for another photopolymer. Both uniform alignment and spatial patterns of different alignment directions can be realized.

The application of the mechanical joining process clinching allows the assembly of different sheet metal materials with a wide range of material thickness configurations, which is of interest for lightweight multi-material structures. In order to be able to predict the clinched joint properties as a function of the individual manufacturing steps, current studies focus on numerical modeling of the entire clinching process chain. It is essential to be able to take into account the influence of the joining process-induced damage on the load-bearing capacity of the joint during the loading phase. This study presents a numerical damage accumulation in the clinching process based on an implemented Hosford-Coulomb failure model using a 3D clinching process model applied on the aluminum alloy EN AW-6014 in temper T4. A correspondence of the experimentally determined failure location with the element of the highest numerically determined damage accumulation is shown. Moreover, the experimentally determined failure behavior is predicted to be in agreement in the numerical loading simulation with transferred pre-damage from the process simulation. }}, author = {{Bielak, Christian Roman and Böhnke, Max and Friedlein, Johannes and Bobbert, Mathias and Mergheim, Julia and Steinmann, Paul and Meschut, Gerson}}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, publisher = {{Materials Research Forum LLC}}, title = {{{Numerical analysis of failure modeling in clinching process chain simulation}}}, doi = {{10.21741/9781644902417-33}}, year = {{2023}}, } @inbook{52696, author = {{Kruse, Anne and Müller, Laura and Ott, Manuel and Koch, Rainer and Hügel, Joachim and Finke, Florian and Winter, Stephan and Gust, Thomas}}, booktitle = {{Personennahe Dienstleistungen der Zukunft}}, isbn = {{9783658388126}}, issn = {{2366-1127}}, publisher = {{Springer Fachmedien Wiesbaden}}, title = {{{proDruck 3D-Druck – Technologie der Industrie 4.0 – als Mittel der Inklusion für Menschen mit Behinderungen in die Arbeitswelt}}}, doi = {{10.1007/978-3-658-38813-3_16}}, year = {{2023}}, } @inbook{52698, author = {{Kruse, Anne and Müller, Laura and Ott, Manuel and Jung, Philipp and Koch, Rainer and Hügel, Joachim and Finke, Florian and Winter, Stephan and Gust, Thomas}}, booktitle = {{Personennahe Dienstleistungen der Zukunft}}, isbn = {{9783658388126}}, issn = {{2366-1127}}, publisher = {{Springer Fachmedien Wiesbaden}}, title = {{{3D-Druck – Eine Technologie als Schlüssel zur Steigerung der Teilhabe}}}, doi = {{10.1007/978-3-658-38813-3_7}}, year = {{2023}}, } @inproceedings{53235, author = {{Lehmann, Isabell and Adali, Tülay and Kruizinga, Pieter and Hunyadi, Borbála}}, booktitle = {{2023 57th Asilomar Conference on Signals, Systems, and Computers}}, publisher = {{IEEE}}, title = {{{Deriving 3D Functional Brain Regions from Multi-Slice Functional Ultrasound Data Using ICA and IVA}}}, doi = {{10.1109/ieeeconf59524.2023.10477081}}, year = {{2023}}, } @inproceedings{48961, author = {{Iftekhar, Mohammed and Gowda, Harshan and Kneuper, Pascal and Sadiye, Babak and Müller, Wolfgang and Scheytt, Christoph}}, booktitle = {{2023 IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium (BCICTS)}}, location = {{Monterey, CA, USA}}, title = {{{A 28-Gb/s 27.2mW NRZ Full-Rate Bang-Bang Clock and Data Recovery in 22 nm FD-SOI CMOS Technology}}}, doi = {{10.1109/BCICTS54660.2023.10310954}}, year = {{2023}}, } @article{54207, author = {{Bartlitz, David}}, journal = {{Entscheidungen zum Wirtschaftsrecht (EWiR)}}, number = {{12}}, pages = {{355--356}}, title = {{{Treuwidrige Darlehenskündigung durch Bank nach Herbeiführung der Zahlungsunfähigkeit des Darlehensnehmers durch eigenmächtige Aufteilung eines eingegangenen Betrags auf verschiedene Verbindlichkeiten.

Differences between news media, public and private actor tweets in topics, tweet characteristics such as tone and opinion expression, links, and specific sentiments toward refugees were analyzed.

This study analysed (i) chronotype/SJL association with visceral fat/skeletal muscle mass, (ii) the attribution to physical activity behaviour, and (iii) chronotype-specific changes in physical activity behaviour in young adults during the Covid-19 pandemic lockdown. Chronotype and SJL were derived from the Munich-Chrono-Type-Questionnaire in 320 German students (age 18–25 years) from September 2019 to January 2020, 156 of these participated in an online follow-up survey in June 2020. Body composition was assessed by bioimpedance analysis at baseline. Multivariable linear regression analyses were used to relate chronotype/SJL to body composition; the contribution of self-reported physical activity was tested by mediation analysis. At baseline, a later chronotype and a larger SJL were associated with a higher visceral fat mass (P<0.05), this relation was notably mediated by the attention to physical activity (P<0.05). Chronotype (P = 0.02) but not SJL (P = 0.87) was inversely associated with skeletal muscle mass. During the pandemic lockdown, chronotype hardly changed, but SJL was reduced. Timing and physical activity behaviour remained in most participants and changes were unrelated to chronotype (all P>0.07). A later chronotype/higher SJL may increase the risk of a higher visceral fat mass even in this relatively healthy sample, which may be partly due to their physical activity behaviour. Despite a reduction in SJL during the pandemic lockdown, later chronotypes did not change their physical activity behaviour more than earlier chronotypes.}}, author = {{Krueger, Betina and Stutz, Bianca and Jankovic, Nicole and Alexy, Ute and Kilanowski, Anna and Libuda, Lars and Buyken, Anette E.}}, issn = {{1932-6203}}, journal = {{PLOS ONE}}, keywords = {{Multidisciplinary}}, number = {{1}}, publisher = {{Public Library of Science (PLoS)}}, title = {{{The association of chronotype and social jet lag with body composition in German students: The role of physical activity behaviour and the impact of the pandemic lockdown}}}, doi = {{10.1371/journal.pone.0279620}}, volume = {{18}}, year = {{2023}}, } @article{41456, abstract = {{Abstract Background The German total diet study (TDS)—BfR MEAL Study—established its food list in 2016 based on food consumption data of children (0.5–<5 years) and adults (14–80 years). The list consists of 356 foods selected for analysis in order to ensure ≥90% coverage of the diet. Recently, new food consumption data for children (0.5–<6 and 6–<12 years) in Germany became available, which raised the opportunity to evaluate the applicability of the MEAL food list 2016 on new data. Objective We tested the hypotheses that the MEAL food list 2016 also covers ≥90% of the diet of the new collected food consumption data, and that the selection of foods from younger children and adults was sufficient to also cover the middle age group (6–<12 years). Strategies for updating the existing food list were assessed. Methods Three approaches evaluated the reusability and potential adjustment strategies of the existing food list. Approach 1 applied the existing food list to new food consumption data. Approach 2 allowed the extension of the existing food list to improve coverage of food consumption. Approach 3 set up a new food list based on the new data. Results The MEAL food list 2016 covered 94% of the overall diet of the new collected food consumption data. The diet of the middle age group was sufficiently covered with 91%. However, coverage on main food group or population subgroup level was <90% in some cases. Approach 3 most accurately identified relevant modifications to the existing food list. 94% of the MEAL food list 2016 could be re-used and 51 new foods were identified as potentially relevant. Significance The results suggest that a high investment in the coverage of a TDS food list will lower the effort and the resources to keep data updated in the long-term. Impact There is no established approach to update a TDS food list. This study provides comparative approaches to handle newly collected food consumption data for follow-on TDS activities. The results provide useful information for institutions planning or updating a TDS. Furthermore, new food consumption data for children in Germany recently became available and are here presented for the first time. }}, author = {{Kolbaum, Anna Elena and Ptok, Sebastian and Jung, Christian and Libuda, Lars and Lindtner, Oliver}}, issn = {{1559-0631}}, journal = {{Journal of Exposure Science & Environmental Epidemiology}}, keywords = {{Public Health, Environmental and Occupational Health, Pollution, Toxicology, Epidemiology}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Reusability of Germany´s total diet study food list upon availability of new food consumption data—comparison of three update strategies}}}, doi = {{10.1038/s41370-023-00522-4}}, year = {{2023}}, } @inproceedings{31849, author = {{Hoffmann, Max and Biehler, Rolf}}, booktitle = {{Proceedings of the Fourth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2022, 19-22 October 2022)}}, editor = {{Trigueros, Marı́a and Barquero, Berta and Hochmuth, Reinhard and Peters, Jana}}, keywords = {{Teaching and learning of specific topics in university mathematics, Transition to, across and from university mathematics, Student Teachers, Geometry, Congruence, Double Discontinuity.}}, publisher = {{University of Hannover and INDRUM.}}, title = {{{Student Teachers ’ Knowledge of Congruence before a University Course on Geometry}}}, year = {{2023}}, } @inproceedings{43097, author = {{Florensa, Ignasio and Hoffmann, Max and Romo Vázquez, Avenilde and Zandieh, Michelle and Martínez-Planell, Rafael}}, booktitle = {{Proceedings of the Fourth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2022, 19-22 October 2022)}}, editor = {{Trigueros, Marı́a and Barquero, Berta and Hochmuth, Reinhard and Peters, Jana}}, title = {{{Innovations in university teaching based on mathematic education research}}}, year = {{2023}}, }
