Elliptic curves over function fields of elliptic curves

, 2015
Die rationalen Punkte auf elliptischen Kurven gehören zu den wichtigsten Objekten der arithmetischen Theorie. Ein Messwert für die Größe der Gruppe der rationalen Punkte einer elliptischen Kurve ist ihr Rang. Dieser ist definiert, als die minimale Anzahl an rationalen Punkten auf der gegebenen elliptischen Kurve, die benötigt werden, um alle solche ...

Additive Manufacturing of Negative Thermal Expansion Metamaterials Using Steels

Advanced Materials Technologies, EarlyView.
Architected lattices with tunable negative thermal expansion are fabricated from common steels using laser powder bed fusion metal additive manufacturing. Optimized multimaterial interfaces and geometry‐driven design produce robust, defect‐minimized structures that remain dimensionally stable up to 300 °C, enabling scalable solutions for thermal ...

Full‐Domain 3D Digital Twin for Comprehensive Analysis and Validation of Standing Surface Acoustic Wave Generation on LiNbO3 Substrate

Advanced Materials Technologies, EarlyView.
A full‐domain 3D digital twin of a standing surface acoustic wave (SSAW) device on 128° YX LiNbO3 is developed and experimentally validated. The predictive power of the model is confirmed by electrical characterisation and laser Doppler vibrometry measurements, which show excellent agreement with simulations.

Nature‐Inspired Functional Aerogel Fibers with Engineerable Core–Shell Morphology

Advanced Materials Technologies, EarlyView.
Nature‐inspired core–shell aerogel fibers are fabricated through coaxial wet‐spinning, which combines a polyimide shell with MXene core. The fibers exhibited absorption‐dominant EMI shielding, low thermal conductivity, and mechanical robustness, demonstrating multifunctional potential for wearable electronics and advanced smart textiles.

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

Advanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on
