The cell set-up is suitable for using powder electrode materials. Reproducibility of our cell assembly is analyzed by preparing two cells containing hard carbon (HC) powder as working electrode and sodium metal as reference electrode. Electrochemical storage properties of HC powder electrode derived from carbonization of sustainable cellulose are studied by ssNMR. 23Na in-situ ssNMR monitors the sodiation/desodiation of a Na{\\textbar}NaPF6{\\textbar}HC cell (cell 1) over a period of 22?days, showing high cell stability. After the galvanostatic process, the HC powder material is investigated by high resolution 23Na ex-situ MAS NMR. The formation of ionic sodium species in different chemical environments is obtained. Subsequently, a second Na{\\textbar}NaPF6{\\textbar}HC cell (cell 2) is sodiated for 11?days achieving a capacity of 220?mAh/g. 23Na ex-situ MAS NMR measurements of the HC powder material extracted from this cell clearly indicate the presence of quasi-metallic sodium species next to ionic sodium species. This observation of quasi-metallic sodium species is discussed in terms of the achieved capacity of the cell as well as of side reactions of sodium in this electrode material."}],"date_created":"2026-02-07T16:12:13Z","keyword":["solid-state nmr","hard carbon","electrochemical cells","in-situ characterization","sodium"],"type":"journal_article","status":"public","_id":"64045","publisher":"John Wiley & Sons, Ltd","page":"e202301300","volume":17,"user_id":"100715","citation":{"mla":"Šić, Edina, et al. “Electrochemical Sodium Storage in Hard Carbon Powder Electrodes Implemented in an Improved Cell Assembly: Insights from In-Situ and Ex-Situ Solid-State NMR.” <i>Chemsuschem</i>, vol. 17, John Wiley &#38; Sons, Ltd, 2023, p. e202301300, doi:<a href=\"https://doi.org/10.1002/cssc.202301300\">10.1002/cssc.202301300</a>.","bibtex":"@article{Šić_Schutjajew_Haagen_Breitzke_Oschatz_Buntkowsky_Gutmann_2023, title={Electrochemical Sodium Storage in Hard Carbon Powder Electrodes Implemented in an Improved Cell Assembly: Insights from In-Situ and Ex-Situ Solid-State NMR}, volume={17}, DOI={<a href=\"https://doi.org/10.1002/cssc.202301300\">10.1002/cssc.202301300</a>}, journal={Chemsuschem}, publisher={John Wiley &#38; Sons, Ltd}, author={Šić, Edina and Schutjajew, Konstantin and Haagen, Ulrich and Breitzke, Hergen and Oschatz, Martin and Buntkowsky, Gerd and Gutmann, Torsten}, year={2023}, pages={e202301300} }","ama":"Šić E, Schutjajew K, Haagen U, et al.

The paper examines the potential of different task settings for mathematical modelling with real objects: outdoors at the real object itself, with photographs and with a 3D model representation. It is the aim of the study to analyze how far the mathematical modelling steps of students solving the tasks differ in comparison to the settings and representations. In a qualitative study, 19 lower secondary school students worked on tasks of all three settings in a Latin square design. Their working processes in the settings are compared with a special focus on the modelling steps Simplifying and Structuring, as well as Mathematizing.

The paper examines the potential of different task settings for mathematical modelling with real objects: outdoors at the real object itself, with photographs and with a 3D model representation. It is the aim of the study to analyze how far the mathematical modelling steps of students solving the tasks differ in comparison to the settings and representations. In a qualitative study, 19 lower secondary school students worked on tasks of all three settings in a Latin square design. Their working processes in the settings are compared with a special focus on the modelling steps Simplifying and Structuring, as well as Mathematizing. The analysis by means of activity diagrams and a qualitative content analysis shows that both steps are particularly relevant when students work with real objects — independent from the three settings.

In this context, wide aperture automotive radars of 1m length or more and resolution close to 0.1° in azimuth and 0.5° in elevation could be beneficial. To enable coherent processing of arrays with such large aperture, prior (i.e offline) and online calibration are necessary: channel imbalances (gains and phases) and three dimensional coordinates of transmit and receive elements need to be determined. We propose a calibration strategy based on alternating steps between the two subtasks of i) channel imbalance estimation with ‘known’ array positions, by applying a singular value decomposition to the resulting tensor calculus problem; and ii) antenna position estimation with ’known’ channel imbalances, by numerically maximizing the Bayesian posterior probability; in both cases operating on range/Doppler snapshots of disjoint targets (with potentially unknown locations). Simulation studies based on the parameters of a MIMO 8x6 linear sparse array show promising results as long as the initial position errors do not exceed half a wavelength (2mm), beyond which we observe strong effects of ambiguity. Experimental results with real measurements show that after calibration in laboratory conditions, our MIMO 8x6 demonstrator with 50cm aperture is able to resolve two targets at the same range with angular separation at least as close as 0.4°.","lang":"eng"}]},{"related_material":{"link":[{"relation":"contains","url":"https://bcicts.org/"}]},"citation":{"bibtex":"@inproceedings{Iftekhar_Nagaraju_Kneuper_Sadiye_Müller_Scheytt_2023, title={A 28-Gb/s 27.2 mW NRZ Full-Rate Bang-Bang Clock and Data Recovery in 22 nm FD-SOI CMOS Technology }, booktitle={BCICTS 2023 IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium}, author={Iftekhar, Mohammed and Nagaraju, Harshan and Kneuper, Pascal and Sadiye, Babak and Müller, Wolfgang and Scheytt, J.

This allows circumventing the expensive and unreliable global volumetric remapping step in the versatile meshing pipeline based on 3D integer-grid maps. In essence, we reduce this step to simpler local cube mapping problems, for which reliable solutions are available. As a consequence, the robustness of the mesh generation process is increased, especially when targeting coarse or block-structured hexahedral meshes.

The growing popularity of 3D printing has also attracted security researchers, who have analyzed possibilities for weakening 3D models or stealing intellectual property from 3D models. We extend these important aspects and provide the first comprehensive security analysis of 3D printing data formats. We performed our systematic study on the example of the 3D Manufacturing Format (3MF), which offers a large variety of features that could lead to critical attacks. Based on 3MF’s features, we systematized three attack goals: Data Exfiltration (dex), Denial of Service, and UI Spoofing (uis). We achieve these goals by exploiting the complexity of 3MF, which is based on the Open Packaging Conventions (OPC) format and uses XML to define 3D models. In total, our analysis led to 352 tests. To create and run these tests automatically, we implemented an open-source tool named 3MF Analyzer (tool), which helped us evaluate 20 applications.","lang":"eng"}],"publication":"Proceedings of the 26th International Symposium on Research in Attacks, Intrusions and Defenses","type":"conference","keyword":["Data Format Security","3D Manufacturing Format","3D Printing","Additive Manufacturing"],"department":[{"_id":"632"}],"file":[{"date_created":"2023-10-16T03:48:08Z","creator":"jrossel","content_type":"application/pdf","file_id":"48065","date_updated":"2024-09-05T11:14:40Z","relation":"main_file","access_level":"open_access","file_size":1054999,"file_name":"Security_Analysis_of_the_3mf_Data_Format.pdf"}],"date_created":"2023-10-11T13:42:09Z","has_accepted_license":"1","status":"public","conference":{"location":"Hongkong","start_date":"2023-10-16","name":"26th International Symposium on Research in Attacks, Intrusions and Defenses","end_date":"2023-10-18"},"ddc":["000"],"user_id":"58331","_id":"48012","publisher":"ACM","quality_controlled":"1","file_date_updated":"2024-09-05T11:14:40Z","citation":{"apa":"Rossel, J., Mladenov, V., &#38; Somorovsky, J.

LLMs particularly challenge algorithms focused on the temporal analysis of topical clusters. Simple similarity measures can no longer capture and map campaigns that were previously broadly similar in content. Herein, we analyze whether the classification of messages over time can be profitably used to rediscover poorly detectable campaigns at the content level. Thus, we evaluate classical classifiers and a new method based on siamese neural networks. Our results show that campaigns can be detected despite the limited reliability of the classifiers as long as they are based on a large amount of simultaneously spread artificial content.","lang":"eng"}],"page":"72–87","publisher":"Springer-Verlag","_id":"52865","user_id":"103682","doi":"10.1007/978-3-031-47896-3_6","status":"public","year":"2023","title":"Lost in Transformation: Rediscovering LLM-Generated Campaigns in Social Media","publication_identifier":{"isbn":["978-3-031-47895-6"]},"author":[{"first_name":"Britta","last_name":"Grimme","full_name":"Grimme, Britta"},{"full_name":"Pohl, Janina","first_name":"Janina","last_name":"Pohl"},{"full_name":"Winkelmann, Hendrik","first_name":"Hendrik","last_name":"Winkelmann"},{"first_name":"Lucas","last_name":"Stampe","full_name":"Stampe, Lucas"},{"last_name":"Grimme","first_name":"Christian","full_name":"Grimme, Christian"}],"date_updated":"2026-03-19T07:48:51Z"},{"date_created":"2023-03-23T08:13:30Z","department":[{"_id":"157"}],"type":"conference","publication":"Materials Research Proceedings","abstract":[{"text":"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.
