However, the results are conflicting. We investigated serum leptin levels in children and adolescents (11 to 18.9 years) with psychiatric disorders ( n  = 363). Absolute and relative (body-mass-index (BMI)-, sex- and pubertal-stage-adjusted z-scores using reference values of healthy children and adolescents) leptin levels of different patient groups according to diagnosis were compared. The association between leptin levels and depression (Beck Depression Inventory-II) and anxiety (Child Behavior Checklist and Youth Self Report) was examined using regression analysis. Leptin z-scores were higher in patients with psychiatric disorders than in healthy controls (median 1.50, p  < .001). While global tests suggested differences in leptin z-scores between patients with different psychiatric disorders, these differences could not be attributed to diagnosis groups in post-hoc pairwise comparisons. Absolute leptin levels differed between psychiatric disorders ( p  < .001). Patients with anorexia nervosa (AN) had the lowest levels, and patients with mood disorders had higher leptin levels than patients with mental disorders other than mood disorders, anxiety or AN. Neither absolute nor relative leptin levels were related to depressive or anxiety symptoms in regression models adjusted for sex and BMI. Significantly elevated BMI-, sex- and puberty-stage-adjusted leptin levels were observed in children and adolescents with psychiatric disorders compared to a reference sample. Further controlled studies are needed to confirm and explain this finding. No relationship was found between absolute or relative leptin levels and symptoms of depression or anxiety. }}, author = {{Albers, Nicola and Antel, Jochen and Föcker, Manuel and Libuda, Lars and Bühlmeier, Judith and Hirtz, Raphael and Seitz, Jochen and Hinney, Anke and Hebebrand, Johannes and Peters, Triinu}}, issn = {{1018-8827}}, journal = {{European Child & Adolescent Psychiatry}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Children and adolescents with psychiatric disorders have high relative leptin levels upon adjustment for sex, BMI, and pubertal status}}}, doi = {{10.1007/s00787-025-02921-4}}, year = {{2026}}, } @article{63880, author = {{Knoll-Pientka, Nadja and Schils, Dorina and Mantwill, Katrin and Dinse, Hannah and Skoda, Eva-Maria and Bäuerle, Alexander and Teufel, Martin and Libuda, Lars}}, issn = {{2055-0928}}, journal = {{BMC Nutrition}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Adherence to dietary recommendations according to the General Dietary Behavior Inventory (GDBI) and its association with bioelectrical impedance analysis (BIA) parameters among young, healthy and normal weight women}}}, doi = {{10.1186/s40795-026-01260-0}}, year = {{2026}}, } @article{64159, abstract = {{ABSTRACT Separation processes, such as distillation and stripping, are highly energy‐intensive.

Although the available lithography techniques are constantly being advanced to push the feature sizes down to the few-nanometer scale, such developments are associated with many technological and economic challenges. Combining established top-down lithography with bottom-up self-assembly strategies has the potential to overcome those challenges and enable the manipulation of matter with molecular precision. One of the most exciting approaches in this regard is to harness the programmability of DNA self-assembly to create precise DNA nanostructure masks to be used in the lithographic patterning of diverse substrates. DNA nanotechnology has provided us with a versatile toolbox for the high-yield synthesis of 2D and 3D nanostructures with complex, user-defined shapes at unprecedented molecular accuracy. Consequently, the last decade has seen intense research efforts aimed at transferring such DNA nanostructure shapes into functional organic and inorganic materials and we have now arrived at a point where sophisticated molecular lithography approaches utilize DNA nanostructure masks for the fabrication of plasmonic surfaces for metamaterials and sensing applications. This review summarizes how the spatial information of such DNA nanostructure masks can be transferred into various organic and inorganic materials through selective etching and deposition steps. The review also discusses recent developments toward all-purpose molecular lithography schemes and highlights promising extensions of the discussed methods toward new materials systems and application fields.}}, author = {{Keller, Adrian Clemens and Linko, Veikko}}, issn = {{0022-3727}}, journal = {{Journal of Physics D: Applied Physics}}, publisher = {{IOP Publishing}}, title = {{{Molecular lithography with DNA nanostructures: Methods and applications}}}, doi = {{10.1088/1361-6463/ae5667}}, year = {{2026}}, } @article{58438, abstract = {{This study presents a numerical approach using a 3D finite element model to quantify the remaining clamp load of a plastic nut joint after a specific time.

Athletes must perceive and process information to adapt movements, yet traditional agility tests often lack cognitive and multidirectional demands. Additionally, modern test systems are mostly stationary. This study evaluated the novel and portable “Functional Agility Square Test” (FAST) for validity, reliability, and usefulness. Methods: To assess discriminant validity, 22 game sports (GS) and 22 non-game sports (NGS) athletes participated in one session. Test–retest reliability was examined with 36 GS athletes (20 female) across three sessions. Participants performed cognitive (FAST_COG), preplanned (FAST_MOT), and randomized (FAST_SAT) reactive change-of-direction tasks, each repeated three times per session. Results: Results showed significantly lower response times (RTs) in GS compared to NGS (p < 0.05). Mean RTs indicated moderate relative reliability (ICC 0.50–0.74), while medians showed moderate to good reliability (ICC 0.59–0.83). Usefulness was evident from the first session (FAST_MOT) or from the third session (FAST_SAT) based on median RTs. Conclusions: Thus, the FAST seems to be valid, reliable, and sensitive for GS-based agility assessment. Its portable setup enables ecologically valid field testing.

Conventionally, the input DC-link voltage is controlled to operate the LLC converter at resonance for the given operating point. However, the DC-link capacitor voltage shows a low-frequency voltage ripple (typically the second harmonic of grid frequency) in cascaded converters so that the LLC has to adapt its switching frequency within the grid period. Conventionally, the LLC converter operates 50% of the time above the resonant frequency of 40 kHz and 50% below resonance. Both operating conditions cause additional losses. However, experimental measurements indicate that the below-resonance operation causes significantly higher losses than above-resonance operation due to much higher primary and secondary transformer currents. It is better to increase the DC-link voltage by 30% of the peak-to-peak low-frequency voltage ripple to mostly avoid below-resonance operation (i.e., from 650 V to 680 V in this case). With the proposed control, the LLC converter operates about 75% of time over resonance and only 25% of time below resonance. The overall efficiency increases from 97.66% to 97.7% for the average operating point with an 80% load current. This corresponds to a 2% total loss reduction. Finally, the peak resonance capacitor voltage decreases from 910 V to 790 V (−13%).}}, author = {{Unruh, Roland and Böcker, Joachim and Schafmeister, Frank}}, issn = {{2079-9292}}, journal = {{Electronics}}, keywords = {{adaptive DC-link voltage, cascaded H-bridge, resonant operation, Full-Bridge Converter, loss minimization, LLC Resonant Converter, peak capacitor voltage reduction}}, number = {{8}}, publisher = {{MDPI AG}}, title = {{{Adaptive DC-Link Voltage Control for 22 kW, 40 kHz LLC Resonant Converter Considering Low-Frequency Voltage Ripple}}}, doi = {{10.3390/electronics14081517}}, volume = {{14}}, year = {{2025}}, } @article{58531, abstract = {{Zusammenfassung Die fortschreitende Digitalisierung stellt Schulen vor Herausforderungen, insbesondere bei der Nutzung digitaler Medien in unterrichtlichen Lehr- und Lernprozessen mit dem Ziel, den (über-) fachlichen Kompetenzerwerb aller Schüler*innen zu unterstützen. Betrachtet man die digitalen Kompetenzen, zeigt sich, dass auch diese sozialen Disparitäten unterliegen. Dennoch lassen sich in ICILS organisational resiliente Schulen identifizieren, deren Schüler*innen trotz herausfordernder Schüler*innenkomposition überdurchschnittliche digitale Kompetenzen erreichen. Studien, die fachspezifische Kompetenzen untersuchen, lassen erkennen, dass organisational resiliente Schulen gemeinsame Merkmale aufweisen. Ein Merkmal, das in diesem Zusammenhang bedeutsam erscheint, ist die Gestaltung von Unterrichtsqualitätsmerkmalen. Digitale Kompetenzen erscheinen diesbezüglich unerforscht, sodass der vorliegende Beitrag mittels Daten aus der BMBF-geförderten qualitativen ICILS-Vertiefungsstudie UneS-ICILS 2018 (Unerwartbar erfolgreiche Schulen im digitalen Wandel) Basisdimensionen von Unterrichtsqualität an resilienten Schulen in Bezug auf digitale Kompetenzen untersucht. Für die Analyse wurden 22 leitfadengestützte Interviews mit Lehrkräften und sieben Gruppeninterviews mit Schüler*innen im Hinblick auf eine ‚effiziente Klassenführung‘, ‚kognitive Aktivierung‘ und ‚konstruktive Unterstützung‘ inhaltsanalytisch ausgewertet. Im Ergebnis zeigt die Analyse der Dimension ‚effiziente Klassenführung‘, dass sich u. a. die Organisation und Struktur mittels digitaler Medien wie beispielsweise durch den Einsatz digitaler Lernplattformen als bedeutende Faktoren herausstellen. Hinsichtlich der ‚kognitiven Aktivierung‘ wird der Einsatz digitaler Tools für das Anknüpfen an individuelles Vorwissen als bedeutend hervorgehoben. Darüber hinaus zeigt sich bei der Dimension ‚konstruktive Unterstützung‘ die Förderung des selbstgesteuerten Lernens und das Ausbilden von Unterstützungsstrukturen zum (kooperativen) Lernen mit digitalen Medien als bedeutsam.

This requires knowledge of the frictional power distribution in the tire contact patch, which is the basis for calculating tire wear using a wear law. Usually, only 3D structural tire models can generate such distributed contact results. However, they involve high computational costs and cannot be used for comprehensive optimization of a vehicle’s suspension system with respect to tire wear characteristics. Hence, this contribution presents a methodology on how to accelerate the prediction of the frictional power distribution using two components: The structural tire model is replaced by an empirical tire model that on its own is not able to generate distributed contact results. Therefore, an artificial neural network is trained to predict the desired contact results from the kinematic quantities calculated by the empirical tire model. In the initial training phase, both components are fitted to data generated by the original complex tire model. After training, the empirical tire model can replace the structural tire model in vehicle simulations, resulting in significantly shorter calculation times. The simulation results are fed into the artificial neural network, which predicts the frictional power distributions over the tire width with negligible additional effort. Overall, the methodology reduces calculation time for the prediction of tire wear based on virtual test drives to approximately 25% of the time needed when using structural tire models.}}, author = {{Muth, Lars and Zharia, Raphael and Sahin, Hürkan and Sextro, Walter}}, journal = {{Tire Science and Technology}}, publisher = {{The Tire Society}}, title = {{{Prediction of the Frictional Power Distribution in the Tire Contact Patch Based on an Empirical Tire Model and an Artificial Neural Network}}}, doi = {{https://doi.org/10.2346/TST-24-009}}, year = {{2025}}, } @article{59229, abstract = {{Die Nahrungszubereitung als zentraler Bestandteil eines haushaltsbezogenen Unterrichts dient der Anbahnung von Kompetenzen für die Zubereitung von Speisen und die Gestaltung von Mahlzeiten unter Berücksichtigung von Gesundheit und Nachhaltigkeit.
