In this study, we explore how analysis of conversations on social media can be used to understand how people feel about heat waves and how they respond. We collected global Twitter data over four months (from January to April 2022) using predefined hashtags about heat waves. Topic modelling identified five topics. The largest (one-third of all tweets) was related to sports events. The remaining two-thirds could be allocated to four topics connected to communication about climate-related heat or heat waves. Two of these were on the impacts of heat and heat waves (health impacts 20%; social impacts 16%), one was on extreme weather and climate change attribution (17%) and the last one was on perceptions and warning (13%). The number of tweets in each week corresponded well with major heat wave occurrences in Argentina, Australia, the USA and South Asia (India and Pakistan), indicating that people posting tweets were aware of the threat from heat and its impacts on the society. Among the words frequently used within the topic ‘Social impacts’ were ‘air-conditioning’ and ‘electricity’, suggesting links between coping strategies and financial pressure. Apart from analysing the content of tweets, new insights were also obtained from analysing how people engaged with Twitter tweets about heat or heat waves. We found that tweets posted early, and which were then shared by other influential Twitter users, were among the most popular. Finally, we found that the most popular tweets belonged to individual scientists or respected news outlets, with no evidence that misinformation about climate change-related heat is widespread. }}, author = {{Zander, Kerstin K. and Rieskamp, Jonas and Mirbabaie, Milad and Alazab, Mamoun and Nguyen, Duy}}, issn = {{0921-030X}}, journal = {{Natural Hazards}}, keywords = {{Earth and Planetary Sciences (miscellaneous), Atmospheric Science, Water Science and Technology}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Responses to heat waves: what can Twitter data tell us?}}}, doi = {{10.1007/s11069-023-05824-2}}, year = {{2023}}, } @article{36877, abstract = {{The study explores differences between three user types in the top tweets about the 2015 “refugee crisis” in Germany and presents the results of a quantitative content analysis.

The miniaturisation of components leads to new demands on measurement systems. One of these is the resolution. As a volumetric analysis method and method of non-destructive testing, industrial X-ray computed tomography (XCT) has the ability to measure geometrical features and their corresponding dimensions without destroying them and can therefore be used for quality assurance. However, the concept of resolution is not trivial for XCT and has not yet been finally clarified. In particular, the interface structural resolution, the detectability of two surfaces facing each other after surface segmentation, faces a lack of a test specimen, a corresponding measurand and a reliable method. Simulation-based XCT investigations of a method to determine this type of resolution are presented in this article using the geometry of a test specimen that contains several radially arranged holes of the same size. The borehole diameters correspond to the distance between the holes to investigate the resolvability of surfaces and interfaces. The evaluation is based on mean and extreme values of grey value profiles between the individual boreholes of the reconstructed volume. It is shown that the geometrical detectability of the test specimen surface and interface can be extended by a reasonable choice of the threshold value for surface segmentation within a defined interval. With regard to the resolving capability, a distinction is made between assured detectability and possible detectability, as well as the threshold value used when using the ISO50 threshold for surface segmentation and measurement chain completion. }}, author = {{Busch, Matthias and Hausotte, Tino}}, issn = {{2194-878X}}, journal = {{Journal of Sensors and Sensor Systems}}, keywords = {{Electrical and Electronic Engineering, Instrumentation}}, number = {{1}}, pages = {{1--8}}, publisher = {{Copernicus GmbH}}, title = {{{Simulation-based investigation of the metrological interface structural resolution capability of X-ray computed tomography scanners}}}, doi = {{10.5194/jsss-12-1-2023}}, volume = {{12}}, year = {{2023}}, } @inproceedings{35893, author = {{zur Heiden, Philipp and Priefer, Jennifer and Beverungen, Daniel}}, booktitle = {{Proceedings of the 56th Conference on System Sciences}}, title = {{{Location-Based Service and Location-Contextualizing Service: Conceptualizing the Co-creation of Value with Location Information}}}, year = {{2023}}, } @inproceedings{36839, author = {{Neumann, Stefan and Meschut, Gerson and Otroshi, Mortaza and Kneuper, Florian and Schulze, Andre and Tekkaya, Erman}}, title = {{{Mechanically Joined Extrusion Profiles for Battery Trays}}}, year = {{2023}}, } @inbook{35681, author = {{Liebendörfer, Michael and Büdenbender-Kuklinski, Christiane and Lankeit, Elisa and Schürmann, Mirko and Biehler, Rolf and Schaper, Niclas}}, booktitle = {{Practice-Oriented Research in Tertiary Mathematics Education}}, isbn = {{9783031141744}}, issn = {{1869-4918}}, pages = {{91--117}}, publisher = {{Springer International Publishing}}, title = {{{Framing Goals of Mathematics Support Measures}}}, doi = {{10.1007/978-3-031-14175-1_5}}, year = {{2023}}, } @inproceedings{37165, author = {{Hofeditz, Lennart and Erle, Lukas and Timm, Lara and Mirbabaie, Milad}}, booktitle = {{Proceedings of the 55th Hawaii International Conference System Sciences (HICSS) (forthcoming)}}, title = {{{How Virtuous are Virtual Influencers?–A Qualitative Analysis of Virtual Actors’ Virtues on Instagram}}}, year = {{2023}}, } @article{33447, author = {{Julin, Sofia and Keller, Adrian and Linko, Veikko}}, issn = {{1043-1802}}, journal = {{Bioconjugate Chemistry}}, keywords = {{Organic Chemistry, Pharmaceutical Science, Pharmacology, Biomedical Engineering, Bioengineering, Biotechnology}}, pages = {{18--29}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Dynamics of DNA Origami Lattices}}}, doi = {{10.1021/acs.bioconjchem.2c00359}}, volume = {{34}}, year = {{2023}}, } @book{37469, editor = {{Biehler, Rolf and Liebendörfer, Michael and Gueudet, Ghislaine and Rasmussen, Chris and Winsløw, Carl}}, isbn = {{9783031141744}}, issn = {{1869-4918}}, publisher = {{Springer International Publishing}}, title = {{{Practice-Oriented Research in Tertiary Mathematics Education}}}, doi = {{10.1007/978-3-031-14175-1}}, year = {{2023}}, } @inproceedings{37497, abstract = {{Since historical times, cartographic maps have revealed spatial relations and enabled decisions and processes.

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.

Data scientists use Jupyter notebook as the de-facto standard for creating and sharing machine-learning based solutions, primarily written in Python. Recent studies have demonstrated, however, that a large portion of Jupyter notebooks available on public platforms are undocumented and lacks a narrative structure. This reduces the readability of these notebooks. To address this shortcoming, this paper presents HeaderGen, a novel tool-based approach that automatically annotates code cells with categorical markdown headers based on a taxonomy of machine-learning operations, and classifies and displays function calls according to this taxonomy. For this functionality to be realized, HeaderGen enhances an existing call graph analysis in PyCG. To improve precision, HeaderGen extends PyCG's analysis with support for handling external library code and flow-sensitivity. The former is realized by facilitating the resolution of function return-types. Furthermore, HeaderGen uses type information to perform pattern matching on code syntax to annotate code cells. The evaluation on 15 real-world Jupyter notebooks from Kaggle shows that HeaderGen's underlying call graph analysis yields high accuracy (96.4% precision and 95.9% recall). This is because HeaderGen can resolve return-types of external libraries where existing type inference tools such as pytype (by Google), pyright (by Microsoft), and Jedi fall short. The header generation has a precision of 82.2% and a recall rate of 96.8% with regard to headers created manually by experts. In a user study, HeaderGen helps participants finish comprehension and navigation tasks faster.

The effects of both systems are intensively debated by EU Member States as they are striving to implement a European tax system. Its introduction would lead to a switch from SA to FA. Moreover, Pillar One of the recent global tax reform includes a mix of both tax base allocation systems. We find that, against the claims of the EU, FA does not necessarily create lower distortions of the factor allocation. Decisive for that assessment is the level of profit shifting under SA.

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{41812, author = {{Luo, Linghui and Piskachev, Goran and Krishnamurthy, Ranjith and Dolby, Julian and Schäf, Martin and Bodden, Eric}}, booktitle = {{IEEE International Conference on Software Testing, Verification and Validation (ICST)}}, title = {{{Model Generation For Java Frameworks}}}, year = {{2023}}, } @inproceedings{41813, author = {{Shivarpatna Venkatesh, Ashwin Prasad and Wang, Jiawei and Li, Li and Bodden, Eric}}, booktitle = {{IEEE International Conference on Software Analysis, Evolution and Reengineering (SANER)}}, title = {{{Enhancing Comprehension and Navigation in Jupyter Notebooks with Static Analysis}}}, year = {{2023}}, } @inbook{41843, author = {{Harnack, Maria}}, booktitle = {{Immaterielles Kulturerbe und regionale Identität – Schützenwesen in Deutschland}}, editor = {{Seng, Eva-Maria and Leineweber, Jonas}}, title = {{{Immaterielles Kulturerbe in Nordrhein-Westfalen.

With this paper, we introduce the notion of accountability management and an accompanying theoretical framework to the literature.

For this reason, a considerable amount of engineering effort has been taken in order to improve the quality of particle sources and system components. At the same time, data analysis and collection methods based on post-selection have been used to mitigate the effect of particle losses. This has allowed for investigating experimentally multi-particle evolutions where the observer lacks knowledge about the system's intermediate propagation states. Nonetheless, the fundamental question how losses affect the behaviour of the surviving subset of a multi-particle system has not been investigated so far. For this reason, here we study the impact of particle losses in a quantum walk of two photons reconstructing the output probability distributions for one photon conditioned on the loss of the other in a known mode and temporal step of our evolution network. We present the underlying theoretical scheme that we have devised in order to model controlled particle losses, we describe an experimental platform capable of implementing our theory in a time multiplexing encoding. In the end we show how localized particle losses change the output distributions without altering their asymptotic spreading properties. Finally we devise a quantum civilization problem, a two walker generalisation of single particle recurrence processes.}}, author = {{Pegoraro, Federico and Held, Philip and Barkhofen, Sonja and Brecht, Benjamin and Silberhorn, Christine}}, issn = {{0031-8949}}, journal = {{Physica Scripta}}, number = {{3}}, publisher = {{IOP Publishing}}, title = {{{Dynamic conditioning of two particle discrete-time quantum walks}}}, doi = {{10.1088/1402-4896/acbcaa}}, volume = {{98}}, year = {{2023}}, } @inproceedings{42666, author = {{Schmolke, Tobias and Meschut, Gerson and Spohr, Sebastian and Eckstein, Lutz and Brunner-Schwer, Christian and Rethmeier, Michael and Nothhelfer-Richter, Rolf and Hilt, Michael}}, location = {{Frankfurt}}, title = {{{Konzeptentwicklung für ein Stahlbatteriegehäuse unter besonderer Berücksichtigung der Fügetechnik und des Korrosionsschutzes}}}, year = {{2023}}, } @inproceedings{42667, author = {{Schmolke, Tobias and Meschut, Gerson}}, location = {{Orlando}}, title = {{{Leak Tightness of Bonded Joints in Battery Housings Under Mechanical and Corrosive Loads}}}, year = {{2023}}, } @book{42680, editor = {{Beverungen, Daniel and Becker, Jörg and Gadeib, Andera and Schmitz, Gertrud}}, isbn = {{9783662658130}}, publisher = {{Springer Berlin Heidelberg}}, title = {{{Interaktive Einkaufserlebnisse in Innenstädten}}}, doi = {{10.1007/978-3-662-65814-7}}, year = {{2023}}, } @inbook{42681, author = {{zur Heiden, Philipp}}, booktitle = {{DASC-PM v1.1 Fallstudien}}, editor = {{Schulz, Michael and Neuhaus, Uwe and Kühnel, Stephan and Rohde, Heiko and Hoseini, Sayed and Theuerkauf, René}}, pages = {{29--38}}, publisher = {{NORDAKADEMIE gAG Hochschule der Wirtschaft}}, title = {{{Projekt FLEMING – Predictive Maintenance von zentralen Komponenten des Mittelspannungsnetzes}}}, year = {{2023}}, } @article{39549, author = {{Haller, Melanie}}, journal = {{Tietze, Katharina/Schnittler, Anna-Brigitta: Mode und Gender.}}, publisher = {{Transcript}}, title = {{{Frauensache(n)?

The model proposed approximates the behavior of the nonlinear scattering (S)-parameters and noise figure of each building block of the TRX chipset by Laplace polynomials and hyperbolic tangent functions. The modular approach of the model allows to optimize hardware components with respect to the entire TRX system, and fault identification with reduced computational effort. The proposed method is validated using the first monolithically integrated photonic radar transceiver chipset and shows excellent agreement with the post layout simulation results and, including the photodiode (PD) bandwidth (BW) degradation, also with the measurements. }}, author = {{Kruse, Stephan and Schwabe, Tobias and Kneuper, Pascal and Meinecke, Marc-Michael and Kurz, Heiko G. and Scheytt, J.

Popular applications are image denoising, sparse regression and machine learning. Since the choice of the regularization parameter is crucial but often difficult, path-following methods are used to approximate the entire regularization path, i.e., the set of all possible solutions for all regularization parameters. Due to their nature, the development of these methods requires structural results about the regularization path. The goal of this article is to derive these results for the case of a smooth objective function which is penalized by a piecewise differentiable regularization term. We do this by treating regularization as a multiobjective optimization problem. Our results suggest that even in this general case, the regularization path is piecewise smooth. Moreover, our theory allows for a classification of the nonsmooth features that occur in between smooth parts. This is demonstrated in two applications, namely support-vector machines and exact penalty methods.}}, author = {{Gebken, Bennet and Bieker, Katharina and Peitz, Sebastian}}, journal = {{Journal of Global Optimization}}, number = {{3}}, pages = {{709--741}}, title = {{{On the structure of regularization paths for piecewise differentiable regularization terms}}}, doi = {{10.1007/s10898-022-01223-2}}, volume = {{85}}, year = {{2023}}, } @article{42966, author = {{Sherman, David A. and Baumeister, Jochen and Stock, Matt S. and Murray, Amanda M. and Bazett-Jones, David M. and Norte, Grant E.}}, issn = {{1530-0315}}, journal = {{Medicine & Science in Sports & Exercise}}, keywords = {{Physical Therapy, Sports Therapy and Rehabilitation, Orthopedics and Sports Medicine}}, publisher = {{Ovid Technologies (Wolters Kluwer Health)}}, title = {{{Weaker Quadriceps Corticomuscular Coherence in Individuals Following ACL Reconstruction during Force Tracing}}}, doi = {{10.1249/mss.0000000000003080}}, volume = {{Publish Ahead of Print}}, year = {{2023}}, } @article{42967, author = {{Büchel, Daniel and Torvik, PØ and Lehmann, Tim and Sandbakk, Ø and Baumeister, Jochen}}, issn = {{0195-9131}}, journal = {{Med Sci Sports Exerc}}, title = {{{The Mode of Endurance Exercise Influences Changes in EEG Resting State Graphs among High-Level Cross-Country Skiers.}}}, year = {{2023}}, } @article{42965, author = {{Sherman, DA and Baumeister, Jochen and Stock, MS and Murray, AM and Bazett-Jones, DM and Norte, GE}}, issn = {{0195-9131}}, journal = {{Med Sci Sports Exerc}}, number = {{3}}, pages = {{440--449}}, title = {{{Inhibition of Motor Planning and Response Selection after Anterior Cruciate Ligament Reconstruction.}}}, volume = {{55}}, year = {{2023}}, }
