This study assessed whether changes in chronotype and social jetlag, are linked to changes in body composition during adolescence. Subjects/methods We used data from the DONALD open cohort study, collected between 2014 and 2019, from 213 adolescents (9–17 years at baseline, 45% females) having at least two measures of chronotype and anthropometry (N = 572). Chronotype was assessed with the Munich Chronotype Questionnaire and defined as: midpoint of sleep corrected for sleep-debt (MSFsc) accumulated over the week (later MSFsc represents later chronotype). Social jetlag (SJL) defines the difference between midpoint of sleep during week and weekend. Calculations for Fat Free Mass Index (FFMI [kg/m2)]) and Fat Mass Index (FMI) [kg/m2)]) were based on body fat percentage, weight, and height. To analyze the associations, we used linear mixed-effect regression models. Finally, the total cohort was split into three biologically relevant age groups (cut-off set at <12 years, ≥12 to ≤15 years and >15 years). Results Median follow-up was 2.1 years. Overall, change toward a later chronotype was significantly related with an increase in FMI (ß: 0.05, 95% CI: 0.01–0.08). A 1 h increase in social jetlag predicted an increase in BMI-SDS of 0.08 SDS units (95% CI: 0.01–0.14) and in FMI of 0.04 kg/m2 (95% CI: 0.003–0.08). Associations were stronger for the age group ≥12 to ≤15 years (p for interaction: <0.001). No relationship was found with FFMI. Conclusions Changes in MSFsc and SJL during adolescence were associated with concurrent changes in BMI-SDS and FMI. The age ≥12 to ≤15 years appears to be a sensitive period in which chronobiological changes were clearly associated with increasing body fatness. }}, author = {{Jankovic, Nicole and Schmitting, Sarah and Krüger, Bettina and Nöthlings, Ute and Buyken, Anette E. and Alexy, Ute}}, issn = {{0954-3007}}, journal = {{European Journal of Clinical Nutrition}}, title = {{{Changes in chronotype and social jetlag during adolescence and their association with concurrent changes in BMI-SDS and body composition, in the DONALD Study}}}, doi = {{10.1038/s41430-021-01024-y}}, year = {{2021}}, } @article{27123, author = {{Poddubnyi, Vladimir I. and Trächtler, Ansgar and Warkentin, Andreas and Henke, Christian}}, journal = {{Russian Engineering Research}}, number = {{3}}, pages = {{198--201}}, publisher = {{Springer}}, title = {{{Model of a Triangular Caterpillar Drive and Analysis of Vertical Vehicle Dynamics}}}, volume = {{41}}, year = {{2021}}, } @inbook{27139, author = {{Foullois, Marc and Kato-Beiderwieden, Anna-Lena and Mlekus, Lisa and Maier, Günter W. and Jenderny, Sascha and Röcker, Carsten and Dietz, Oliver and Pretzlaff, Matthias and Huxdorf, Oliver and von Dungern, Friedrich and Bräutigam, Dieter and Seifert, Lars and Dumitrescu, Roman}}, booktitle = {{Arbeit in der digitalisierten Welt - Praxisbeispiele und Gestaltungslösungen aus dem BMBF-Förderschwerpunkt}}, editor = {{Bauer, Wilhelm and Mütze-Niewöhner, Susanne and Stowasser, Sascha and Zanker, Claus and Müller, Nadine}}, pages = {{239--255}}, publisher = {{Springer Vieweg, Berlin, Heidelberg}}, title = {{{Arbeit 4.0 in der Produktentstehung mit IviPep}}}, year = {{2021}}, } @inproceedings{27140, abstract = {{Hardly any other area has as much disruptive potential as digital platforms in the course of digitalization. After serious changes have already taken place in the B2C sector with platforms such as Amazon and Airbnb, the B2B sector is on the threshold to the so-called platform economy. In mechanical engineering, pioneers like GE (PREDIX) and Claas (365FarmNet) are trying to get their hands on the act. This is hardly a promising option for small and medium-sized companies, as only a few large companies will survive. Small and medium-sized enterprises (SMEs) are already facing the threat of losing direct consumer contact and becoming exchangeable executers. In order to prevent this, it is important to anticipate at an early stage which strategic options exist for the future platform economy and which adjustments to the product program should already be initiated today. Basically, medium-sized companies in particular lack a strategy for an advantageous entry into the future platform economy. The paper presents different approaches to master the challenges of participating in the platform economy by using platform patterns. Platform patterns represent proven principles of already existing platforms. We show how we derived a catalogue with 37 identified platform patterns. The catalogue has a generic design and can be customized for a specific use case. The versatility of the catalogue is underlined by three possible applications: (1) platform ideation, (2) platform development, and (3) platform characterization.}}, author = {{Drewel, Marvin and Özcan, Leon and Gausemeier, Jürgen and Dumitrescu, Roman}}, booktitle = {{Journal of the Knowledge Economy}}, editor = {{Carayannis, Elias G. }}, keywords = {{Digitalization, Digital platforms, Platform economy, Multisided markets, B2B platforms}}, pages = {{519--543}}, publisher = {{Springer}}, title = {{{Platform Patterns - Using Proven Principles to Develop Digital Platforms}}}, doi = {{10.1007/s13132-021-00772-3}}, volume = {{Volume 12}}, year = {{2021}}, } @inproceedings{27141, author = {{Rasor, Rik and Göllner, Denis and Bernijazov, Ruslan and Kaiser, Lydia and Dumitrescu, Roman}}, booktitle = {{Procedia CIRP}}, pages = {{229--234}}, publisher = {{Elsevier}}, title = {{{Towards collaborative life cycle specification of digital twins in manufacturing value chains}}}, volume = {{98}}, year = {{2021}}, } @inproceedings{27142, author = {{Asmar, Laban and Grigoryan, Khoren and Low, Cheng Yee and Röltgen, Daniel and Kühn, Arno and Dumitrescu, Roman}}, booktitle = {{International Journal of Integrated Engineering }}, number = {{2}}, pages = {{229--240}}, title = {{{Structuring Framework for Early Validation of Product Ideas}}}, volume = {{13}}, year = {{2021}}, } @phdthesis{27158, author = {{Luo, Linghui}}, publisher = {{Universität Paderborn}}, title = {{{Improving Real-World Applicability of Static Taint Analysis}}}, year = {{2021}}, }
