Methods We used repeatedly collected data from n = 196 adolescents (age 9–16 years, providing N = 401 yearly questionnaires) of the DONALD open cohort study. Chronotype was assessed by the Munich Chronotype Questionnaire from which midpoint of sleep (MSFsc) was derived. A sex- and age-specific diet-chrono-alignment score (DCAS) was calculated as the difference in hours between the chronotype-specific median timing of highest caloric intake of the studied population and the individual timing of ‘highest caloric intake’ or vice versa. Repeated-measures regression models were applied to study cross-sectional and longitudinal associations between the DCAS and body composition, e.g., Fat Mass Index (FMI) or Fat Free Mass Index (FFMI). Results DCAS ranged from −6:42 h to + 8:01 h and was not associated with body composition. Among adolescents with a later chronotype (N = 201) a 1 h increase in DCAS (later consumption of ‘highest caloric intake’ in comparison to the median intake of that group), increased FFMI by 1.92 kg/m2 (95% CI: 0.15, 3.69, p value = 0.04) over a median follow-up of 0.94 year. Conclusion Alignment of energy intake with individual chronotype appears beneficial for FFMI among those with a late chronotype. }}, author = {{Jankovic, Nicole and Schmitting, Sarah and Stutz, Bianca and Krüger, Bettina and Buyken, Anette and Alexy, Ute}}, issn = {{1436-6207}}, journal = {{European Journal of Nutrition}}, keywords = {{Nutrition and Dietetics, Medicine (miscellaneous)}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Alignment between timing of ‘highest caloric intake’ and chronotype in relation to body composition during adolescence: the DONALD Study}}}, doi = {{10.1007/s00394-023-03259-w}}, year = {{2023}}, } @inproceedings{46069, author = {{Seebauer, Fritz and Kuhlmann, Michael and Haeb-Umbach, Reinhold and Wagner, Petra}}, booktitle = {{12th Speech Synthesis Workshop (SSW) 2023}}, title = {{{Re-examining the quality dimensions of synthetic speech}}}, year = {{2023}}, } @inproceedings{48475, author = {{Görel, Gamze and Finke, Pauline and Hellmich, Frank}}, location = {{Münster}}, publisher = {{Universität Münster}}, title = {{{Professionelle Unterrichtswahrnehmung von Lehramtsstudierenden – das Projekt iDEAL.

However, this requires a large number of simulations with varying parameters and/or input pulses, which renders numerical studies expensive. This article investigates how we can use data-driven surrogate models based on the Koopman operator to accelerate this process. In order to be successful, we require a model that is accurate over a large number of time steps. To this end, we employ a bilinear Koopman model using extended dynamic mode decomposition and simulate the optical Bloch equations for an ensemble of inhomogeneously broadened two-level systems. Such systems are well suited to describe the excitation of excitonic resonances in semiconductor nanostructures, for example, ensembles of semiconductor quantum dots. We perform a detailed study on the required number of system simulations such that the resulting data-driven Koopman model is sufficiently accurate for a wide range of parameter settings. We analyze the L2 error and the relative error of the photon echo peak and investigate how the control positions relate to the stabilization. After proper training, the dynamics of the quantum ensemble can be predicted accurately and numerically very efficiently by our methods.}}, author = {{Peitz, Sebastian and Hunstig, Anna and Rose, Hendrik and Meier, Torsten}}, title = {{{Accelerating the analysis of optical quantum systems using the Koopman operator}}}, year = {{2023}}, } @article{48500, author = {{Namujju, Lillian Donna and Acquah-Swanzy, Henrietta and Ngoti, Irene F.}}, issn = {{0301-4215}}, journal = {{Energy Policy}}, keywords = {{Management, Monitoring, Policy and Law, General Energy}}, publisher = {{Elsevier BV}}, title = {{{An IAD framework analysis of minigrid institutions for sustainable rural electrification in East Africa: A comparative study of Uganda and Tanzania}}}, doi = {{10.1016/j.enpol.2023.113742}}, volume = {{182}}, year = {{2023}}, } @inproceedings{48532, author = {{Philipo, Godiana Hagile and Kakande, Josephine Nakato and Krauter, Stefan}}, booktitle = {{Proceedings of the 2023 IEEE PES/IAS PowerAfrica Conference}}, location = {{Marrakech, Morocco}}, title = {{{Combined Economic and Emission Dispatch of a Microgrid Considering Multiple Generators}}}, year = {{2023}}, } @inproceedings{48533, author = {{Kakande, Josephine Nakato and Philipo, Godiana Hagile and Krauter, Stefan}}, booktitle = {{Proceedings of the 2023 IEEE PES/IAS PowerAfrica Conference}}, location = {{Marrakech, Morocco}}, title = {{{Demand side management potential of refrigeration appliances}}}, year = {{2023}}, } @inproceedings{48531, author = {{Philipo, Godiana Hagile and Kakande, Josephine Nakato and Krauter, Stefan}}, booktitle = {{Proceedings of the 2023 IEEE AFRICON, Nairobi, Kenya}}, location = {{ Nairobi, Kenya}}, title = {{{Demand-Side-Management for Optimal dispatch of an Isolated Solar Microgrid}}}, year = {{2023}}, } @inproceedings{48570, author = {{Lenz, Cederic and Henke, Christian and Trächtler, Ansgar}}, booktitle = {{2023 IEEE 21st International Conference on Industrial Informatics (INDIN)}}, publisher = {{IEEE}}, title = {{{A Methodical Approach to Hybrid Modelling for Contextual Anomaly Detection on Time-Series Data}}}, doi = {{10.1109/indin51400.2023.10218108}}, year = {{2023}}, } @inproceedings{48572, abstract = {{Abstract. To increase the sustainability of forming processes such as punch bending, homogenization of the processed semi-finished product is an essential step in the manufacturing process. High-strength wire materials are usually available as strip material before being further processed in a forming process. For storage and transport, the material is coiled onto coils and transported to the customer. During the coiling process, residual stresses and plastic deformation are introduced into the wire. Thus, the final product quality is also influenced by the geometry of the coil. Straightening machines are used in production lines to compensate for these. Once a straightening machine has been set up, the settings for the roll positions are usually not changed. As a result, there is no reaction to material fluctuations, which means that the components to be produced do not meet the dimensional accuracy requirements. This leads to an increase in the rejection rate in manufacturing processes. To reduce the rejection rate, it is necessary to enable dynamic and flexible infeed of the straightening rollers. In this context, an innovative control concept with disturbance compensation was developed for the straightening process. The disturbance compensation uses a disturbance model that predicts the change in bending curvature over the coil radius. With this prediction, the straightening machine can be adjusted specifically. The roller positions are adjusted by a subordinate position control. The additional feedback from measured geometric product properties from the following punching-bending process enables the straightening machine to be adjusted even in the case of unforeseen fluctuations in the material properties. In this way, it is possible to react to any material fluctuations as required. This novel, demand-oriented adjustment of the straightening machine is expected to result in a high increase in the efficiency of the production process and a reduction of the rejection rate. }}, author = {{Bathelt, Lukas and Djakow, Eugen and Henke, Christian and Trächtler, Ansgar}}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, publisher = {{Materials Research Forum LLC}}, title = {{{Innovative self-learning disturbance compensation for straightening processes}}}, doi = {{10.21741/9781644902479-216}}, year = {{2023}}, } @inproceedings{48001, author = {{Bathelt, Lukas and Djakow, Eugen and Dahms, Frederik and Henke, Christian and Trächtler, Ansgar and Homberg, Werner}}, booktitle = {{Ilmenauer Federntag 2023: Neueste Erkenntnisse zu Funktion, Berechnung, Prüfung und Gestaltung von Federn und Werkstoffen}}, isbn = {{978-3-948595-09-8}}, location = {{Ilmenau}}, publisher = {{ISLE Steuerungstechnik und Leistungselektronik}}, title = {{{Neuartiger Ansatz zum Richten von zwei- und dreidimensionalen Fehlern an einem Federdraht}}}, year = {{2023}}, } @inproceedings{48571, author = {{Koppert, Steven and Bause, Maximilian and Henke, Christian and Trächtler, Ansgar}}, booktitle = {{2023 IEEE 21st International Conference on Industrial Informatics (INDIN)}}, publisher = {{IEEE}}, title = {{{Learning the Automated Setup of Profile Wrapping Lines for New Products from Few Past Setups}}}, doi = {{10.1109/indin51400.2023.10217972}}, year = {{2023}}, } @article{48588, abstract = {{Bacterial colonization and biofilm formation on abiotic surfaces are initiated by the adhesion of peptides and proteins.

This study investigates the molecular adhesion of a pilus‐derived peptide that facilitates biofilm formation of Pseudomonas aeruginosa, a multidrug‐resistant opportunistic pathogen frequently encountered in healthcare settings. Single‐molecule force spectroscopy (SMFS) was performed on chemically etched ZnO surfaces to gather insights about peptide adsorption force and its kinetics. Metal‐free click chemistry for the fabrication of peptide‐terminated SMFS cantilevers was performed on amine‐terminated gold cantilevers and verified by X‐ray photoelectron spectroscopy (XPS) and polarization‐modulated infrared reflection absorption spectroscopy (PM‐IRRAS). Atomic force microscopy (AFM) and XPS analyses reveal stable topographies and surface chemistries of the substrates that are not affected by SMFS. Rupture events described by the worm‐like chain model (WLC) up to 600 pN were detected for the non‐polar ZnO(11‐20) surfaces.
