This study assessed whether changes in chronotype and social jetlag, are linked to changes in body composition during adolescence.\r\n \r\n Subjects/methods\r\n 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).\r\n \r\n Results\r\n 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.\r\n \r\n Conclusions\r\n 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.\r\n ","lang":"eng"}],"status":"public","_id":"27114","user_id":"49428","department":[{"_id":"35"},{"_id":"22"},{"_id":"571"}],"language":[{"iso":"eng"}]},{"title":"Ebenen der genetischen Analyse komplexer Phänotypen am Beispiel der Anorexia nervosa und der Varianz des Körpergewichts","doi":"10.1024/1422-4917/a000829","date_updated":"2022-01-06T06:57:42Z","date_created":"2021-11-18T19:30:20Z","author":[{"full_name":"Hirtz, Raphael","last_name":"Hirtz","first_name":"Raphael"},{"full_name":"Zheng, Yiran","last_name":"Zheng","first_name":"Yiran"},{"last_name":"Rajcsanyi","full_name":"Rajcsanyi, Luisa S.","first_name":"Luisa S."},{"orcid":"0000-0003-1603-3133","last_name":"Libuda","id":"88682","full_name":"Libuda, Lars","first_name":"Lars"},{"first_name":"Jochen","last_name":"Antel","full_name":"Antel, Jochen"},{"first_name":"Triinu","full_name":"Peters, Triinu","last_name":"Peters"},{"last_name":"Hebebrand","full_name":"Hebebrand, Johannes","first_name":"Johannes"},{"first_name":"Anke","full_name":"Hinney, Anke","last_name":"Hinney"}],"year":"2021","citation":{"apa":"Hirtz, R., Zheng, Y., Rajcsanyi, L.

Genetische Varianten beeinflussen die Gewichtsregulation und die Entwicklung von Essstörungen. Zunächst haben familienbasierte, sogenannte formalgenetische Studien den erblichen Anteil an der Gewichtsregulation und an der Ätiologie von Essstörungen beleuchtet. In einer Vielzahl von Studien zeigten sich sowohl für die Varianz des Körpergewichts als auch für die Entstehung von Essstörungen Erblichkeitsschätzer (Heritabilitätsraten) von über 50 %. Mit diesem Wissen begab man sich in den 90er-Jahren des letzten Jahrhunderts auf die Suche nach den zugrundeliegenden Genen (genauer: genetischen Varianten), die das Körpergewicht, das Essverhalten oder beide Phänotypen auf Grundlage geteilter Mechanismen beeinflussen. Zunächst wurden Kandidatengenstudien durchgeführt. Dabei untersuchte man auf Grundlage unterschiedlicher, v. a. aber pathophysiologisch plausibler Überlegungen Gene mit hoher Relevanz für die untersuchten Phänotypen. Dieser Ansatz war für Essstörungen nicht sehr erfolgreich, für die Gewichtsregulation konnte eine Handvoll Gene identifiziert werden. Verbunden mit großen methodischen Fortschritten in der genetischen Forschung und v. a. der Etablierung sogenannter genomweiter Assoziationsstudien (GWAS) Anfang der 2000er-Jahre konnten bislang über 1000 Varianten/Genorte detektiert werden, die das Körpergewicht beeinflussen. Für die Essstörung Anorexia nervosa (AN) sind aktuell acht solcher Genorte beschrieben. Diese Ergebnisse, aber auch aktuelle Ansätze zu phänotypübergreifenden Analysen lassen Einblicke in die komplexe Regulation des Körpergewichtes zu und haben zudem unerwartete Pathomechanismen für AN aufgezeigt.

Einleitung: Klassische ernährungsepidemiologische Studien (Beobachtungsstudien und randomisierte Interventionsstudien) zeigen, dass die Ernährung ein wichtiger Ansatzpunkt für die Prävention und Therapie psychischer Störungen sein könnte. Diese Studientypen haben allerdings Limitationen, die bei der Ergebnisinterpretation berücksichtigt werden müssen. In dieser narrativen übersichtsarbeit wird beschrieben, wie genetische Studien ein Bindeglied darstellen können, um einen Zusammenhang zwischen Ernährung und psychischen Störungen herzustellen. Methodik: Im Artikel werden verschiedene Ansätze genetischer phänotypübergreifender Analysen sowie Beispiele für deren Anwendungen in der ernährungspsychiatrischen Forschung beschrieben. Darüber hinaus werden spezifische Voraussetzungen sowie Stärken und Schwächen diskutiert. Ergebnisse: Als Methoden genetischer phänotypübergreifender Analysen sind im Rahmen ernährungspsychiatrischer Forschung bislang genetische Korrelationsanalysen, Look-up-Analysen sowie Mendelsche Randomisierungsstudien (MR-Studien) eingesetzt worden. Genetische Korrelationsanalysen und Look-up-Analysen geben erste Hinweise auf mögliche genetische überlappungen zwischen einer psychischen Störung und einem Stoffwechselweg und/oder der Versorgung mit einem spezifischen Nährstoff. MR-Studien sind weitergehende Detailanalysen mit dem Ziel, Kausalzusammenhänge zu identifizieren, beinhalten allerdings sehr spezifische Grundvoraussetzungen für ihre Durchführung. Schlussfolgerung: Genetische phänotypübergreifende Analysen sind eine sinnvolle Ergänzung der klassischen Ernährungsepidemiologie. Insbesondere signifikante Ergebnisse von MR-Studien sind eine wichtige Grundlage zur Entwicklung geeigneter Ernährungsinterventionen, die in nachfolgenden randomisiert kontrollierten Interventionsstudien mit deutlich erhöhter Erfolgsaussicht getestet werden können. Sie sind somit wichtige Instrumente einer effizienten ernährungspsychiatrischen Forschung.

Data from 273 adolescents diagnosed with MDD from two single center cross-sectional studies were used for analysis. Serum levels of thyrotropin (TSH), free levothyroxine (fT4), and cortisol were determined as indicators of basal HPT and HPA axis functioning and compared to that of adolescent controls by t-tests. Quantile regression was employed in the sample of adolescents with MDD to investigate the relationship between both axes in the normal as well as the pathological range of cortisol levels, considering confounders of both axes. In adolescent MDD, cortisol levels and TSH levels were significantly elevated in comparison to controls (p = <.001, d = 1.35, large effect size, and p = <.001, d = 0.79, moderate effect size, respectively). There was a positive linear relationship between TSH and cortisol (p = .003, d = 0.25, small effect size) at the median of cortisol levels (50th percentile). However, no relationship between TSH and cortisol was found in hypercortisolemia (cortisol levels at the 97.5th percentile). These findings imply that HPT and HPA axis dysfunction is common in adolescents with MDD and that function of both axes is only loosely related. Moreover, the regulation of the HPA and HPT axis are likely subjected to age-related maturational adjustments since findings of this study differ from those reported in adults."}],"status":"public"},{"publication":"Vortrag in: automotive CAE Grand Challange","type":"conference_abstract","status":"public","_id":"27702","department":[{"_id":"157"}],"user_id":"66192","language":[{"iso":"eng"}],"year":"2021","citation":{"apa":"Helbig, M., Haufe, A., Beule, F., Aubel, T., Meschut, G., Jamei, S., Fürle, F., Lossau, S., Droste, A., Gleich, H., Kose, K., Sommer, D., & Facciotto, S.

In the 12 years since the last edition of the tables, a large amount of new data has become available.\r\n \r\n \r\n Objectives\r\n To systematically review and tabulate published and unpublished sources of reliable GI values, including an assessment of the reliability of the data.\r\n \r\n \r\n Methods\r\n This edition of the tables lists over 4000 items, a 61% increase in the number of entries compared to the 2008 edition. The data have been separated into 2 lists. The first represents more precise values derived using the methodology recommended by the International Standards Organization (∼2100 items). The second list contains values determined using less robust methods, including using limited numbers of healthy subjects or with a large SEM (∼1900 food items).\r\n \r\n \r\n Results\r\n Dairy products, legumes, pasta, and fruits were usually low-GI foods (≤55 on the 100-point glucose scale) and had consistent values around the world. Cereals and cereal products, however, including whole-grain or whole-meal versions, showed wide variation in GI values, presumably arising from variations in manufacturing methods. Breads, breakfast cereals, rice, savory snack products, and regional foods were available in high-, medium-, and low-GI versions. Most varieties of potato were high-GI foods, but specific low-GI varieties have now been identified.\r\n \r\n \r\n Conclusions\r\n The availability of new data on the GIs of foods will facilitate wider research and application of the twin concepts of GI and GL. Although the 2021 edition of the tables improves the quality and quantity of GI data available for research and clinical practice, GI testing of regional foods remains a priority. This systematic review was registered in PROSPERO as #171204.\r\n ","lang":"eng"}],"status":"public","publication":"The American Journal of Clinical Nutrition","type":"journal_article","language":[{"iso":"eng"}],"_id":"27793","department":[{"_id":"17"},{"_id":"22"},{"_id":"571"}],"user_id":"61597","year":"2021","page":"1625-1632","citation":{"apa":"Atkinson, F.

In the work presented herein, a measurement procedure for the ultrasonic characterization of mechanical properties of homogeneous and fiber-reinforced thermoplastic polymer materials is presented, considering the different degrees of anisotropy. For this, acoustic Lamb waves are excited in a plate-shaped specimen using high-energy laser pulses, and then recorded.Based on the dispersive characteristics of the detected waveguide modes, an inverse procedure is applied to identify the parameters of a linear-elastic material model. Further, a procedure for completely characterising the orthotropy of materials like fiber-reinforced composites using a two-dimensional simulation model is presented. The measurement procedure is verified by examining artificially aged homogeneous polymers and composites, also considering the applicability of results to the quasistatic case.

A multifunctional myoelectric prosthesis controlled using pattern classification can be used to restore some of the lost motor abilities. However, learning to control an advanced prosthesis can be a challenging task, but virtual and augmented reality (AR) provide means to create an engaging and motivating training.\n \n Methods\n In this study, we present a novel training framework that integrates virtual elements within a real scene (AR) while allowing the view from the first-person perspective. The framework was evaluated in 13 able-bodied subjects and a limb-deficient person divided into intervention (IG) and control (CG) groups. The IG received training by performing simulated clothespin task and both groups conducted a pre- and posttest with a real prosthesis. When training with the AR, the subjects received visual feedback on the generated grasping force. The main outcome measure was the number of pins that were successfully transferred within 20 min (task duration), while the number of dropped and broken pins were also registered. The participants were asked to score the difficulty of the real task (posttest), fun-factor and motivation, as well as the utility of the feedback.\n \n Results\n The performance (median/interquartile range) consistently increased during the training sessions (4/3 to 22/4). While the results were similar for the two groups in the pretest, the performance improved in the posttest only in IG. In addition, the subjects in IG transferred significantly more pins (28/10.5 versus 14.5/11), and dropped (1/2.5 versus 3.5/2) and broke (5/3.8 versus 14.5/9) significantly fewer pins in the posttest compared to CG. The participants in IG assigned (mean ± std) significantly lower scores to the difficulty compared to CG (5.2 ± 1.9 versus 7.1 ± 0.9), and they highly rated the fun factor (8.7 ± 1.3) and usefulness of feedback (8.5 ± 1.7).\n \n Conclusion\n The results demonstrated that the proposed AR system allows for the transfer of skills from the simulated to the real task while providing a positive user experience. The present study demonstrates the effectiveness and flexibility of the proposed AR framework. Importantly, the developed system is open source and available for download and further development.\n ","lang":"eng"}],"author":[{"first_name":"Alexander","full_name":"Boschmann, Alexander","last_name":"Boschmann"},{"full_name":"Neuhaus, Dorothee","last_name":"Neuhaus","first_name":"Dorothee"},{"last_name":"Vogt","full_name":"Vogt, Sarah","first_name":"Sarah"},{"last_name":"Kaltschmidt","full_name":"Kaltschmidt, Christian","first_name":"Christian"},{"last_name":"Platzner","full_name":"Platzner, Marco","first_name":"Marco"},{"first_name":"Strahinja","full_name":"Dosen, Strahinja","last_name":"Dosen"}],"date_created":"2021-02-22T10:43:02Z","date_updated":"2022-01-06T06:54:52Z","doi":"10.1186/s12984-021-00822-6","title":"Immersive augmented reality system for the training of pattern classification control with a myoelectric prosthesis","publication_identifier":{"issn":["1743-0003"]},"publication_status":"published","citation":{"short":"A.

Furthermore, the systems may be underactuated and contain kinematic loops and are thus described by a set of differential-algebraic equations that cannot be reformulated as ordinary differential equations in general. We propose a control strategy which combines a feedforward controller based on the servo-constraints approach with a feedback controller based on a recent funnel control design. As an important tool for both approaches, we present a new procedure to derive the internal dynamics of a multibody system. Furthermore, we present a feasible set of coordinates for the internal dynamics avoiding the effort involved with the computation of the Byrnes–Isidori form. The control design is demonstrated by a simulation for a nonlinear non-minimum phase multi-input, multi-output robotic manipulator with kinematic loop.","lang":"eng"}],"type":"journal_article","publication":"Nonlinear Dynamics","language":[{"iso":"eng"}],"user_id":"78640","_id":"22206","citation":{"chicago":"Berger, Thomas, Svenja Drücker, Lukas Johannes Lanza, Timo Reis, and Robert Seifried. “Tracking Control for Underactuated Non-Minimum Phase Multibody Systems.” Nonlinear Dynamics, 2021. https://doi.org/10.1007/s11071-021-06458-4.","ieee":"T.

Remarquably, this algorithm exploits the fact that during its execution, many collisions of robots occur. Such collisions are interpreted as a success because it is assumed that such collided robots behave the same from now on. This is acceptable under the assumption that each robot is represented by a single point. Otherwise, collisions should be avoided. In this paper, we consider a continuous Go-To-The-Center algorithm in which the robots continuously observe the positions of their neighbors and adapt their speed (assuming a speed limit) and direction. Our first results are time bounds of O(n2) for gathering in two dimensions Euclidean space, and Θ(n) for the one dimension. Our main contribution is the introduction and evaluation of a continuous algorithm which performs Go-To-The-Center considering only the neighbors of a robot with respect to the Gabriel subgraph of the visibility graph, i.e. Go-To-The-Gabriel-Center algorithm. We show that this modification still correctly executes gathering in one and two dimensions, with the same time bounds as above. Simulations exhibit a severe difference of the behavior of the Go-To-The-Center and the Go-To-The-Gabriel-Center algorithms: Whereas lots of collisions occur during a run of the Go-To-The-Center algorithm, typically only one, namely the final collision occurs during a run of the Go-To-The-Gabriel-Center algorithm. We can prove this “collisionless property” of the Go-To-The-Gabriel-Center algorithm for one dimension. In two-dimensional Euclidean space, we conjecture that the “collisionless property” holds for almost every initial configuration. We support our conjecture with measurements obtained from the simulation where robots execute both continuous Go-To-The-Center and Go-To-The-Gabriel-Center algorithms.\r\n","lang":"eng"}]},{"abstract":[{"lang":"eng","text":"Abstract\r\n Doxorubicin (DOX) is a common drug in cancer chemotherapy, and its high DNA-binding affinity can be harnessed in preparing DOX-loaded DNA nanostructures for targeted delivery and therapeutics. Although DOX has been widely studied, the existing literature of DOX-loaded DNA-carriers remains limited and incoherent. Here, based on an in-depth spectroscopic analysis, we characterize and optimize the DOX loading into different 2D and 3D scaffolded DNA origami nanostructures (DONs). In our experimental conditions, all DONs show similar DOX binding capacities (one DOX molecule per two to three base pairs), and the binding equilibrium is reached within seconds, remarkably faster than previously acknowledged. To characterize drug release profiles, DON degradation and DOX release from the complexes upon DNase I digestion was studied. For the employed DONs, the relative doses (DOX molecules released per unit time) may vary by two orders of magnitude depending on the DON superstructure. In addition, we identify DOX aggregation mechanisms and spectral changes linked to pH, magnesium, and DOX concentration. These features have been largely ignored in experimenting with DNA nanostructures, but are probably the major sources of the incoherence of the experimental results so far. Therefore, we believe this work can act as a guide to tailoring the release profiles and developing better drug delivery systems based on DNA-carriers."}],"status":"public","type":"journal_article","publication":"Nucleic Acids Research","language":[{"iso":"eng"}],"_id":"22637","user_id":"48864","department":[{"_id":"302"}],"year":"2021","citation":{"mla":"Ijäs, Heini, et al. “Unraveling the Interaction between Doxorubicin and DNA Origami Nanostructures for Customizable Chemotherapeutic Drug Release.” Nucleic Acids Research, vol. 49, 2021, pp. 3048–62, doi:10.1093/nar/gkab097.","short":"H.

One crucial building block are\r\ntailored nanoscale integratable quantum light sources, matching the specific\r\nneeds of use-cases. Several different approaches to realize solid-state quantum\r\nemitters [2] with high performance [3] have been pursued. However, the\r\nproperties of the emitted single photons are always defined by the individual\r\nquantum light source and despite numerous quantum emitter tuning\r\ntechniques [4-7], scalability is still a major challenge. Here we show an\r\nemitter-independent method to tailor and control the properties of the single\r\nphoton emission. We demonstrate a laser-controlled down-conversion process from\r\nan excited state of a quantum three-level system [8]. Starting from a biexciton\r\nstate, a tunable control laser field defines a virtual state in a stimulated\r\nprocess. From there, spontaneous emission to the ground state leads to\r\noptically controlled single photon emission. Based on this concept, we\r\ndemonstrate energy tuning of the single photon emission with a control laser\r\nfield. The nature of the involved quantum states furthermore provides a unique\r\nbasis for the future control of polarization and bandwidth, as predicted by\r\ntheory [9,10]. Our demonstration marks an important step towards tailored\r\nsingle photon emission from a photonic quantum system based on quantum optical\r\nprinciples."}]},{"citation":{"mla":"Derrick, John, et al. “On Strong Observational Refinement and Forward Simulation.” Proceedings of the 35th International Symposium on Distributed Computing (DISC), Schloß Dagstuhl.","bibtex":"@inproceedings{Derrick_Doherty_Dongol_Schellhorn_Wehrheim, series={Leibniz International Proceedings in Informatics}, title={On Strong Observational Refinement and Forward Simulation}, booktitle={Proceedings of the 35th International Symposium on Distributed Computing (DISC)}, publisher={Schloß Dagstuhl}, author={Derrick, John and Doherty, Simon and Dongol, Brijesh and Schellhorn, Gerhard and Wehrheim, Heike}, collection={Leibniz International Proceedings in Informatics} }","short":"J.
