Quantum Transport in SnTe Nanowire Devices

Advanced Electronic Materials, EarlyView.
A variety of quantum transport experiments are observed in SnTe nanowire devices and attributed to microscopic differences in the fabrication. Three categories can be distinguished: semiconducting behavior, partial superconductivity and Fabry‐Pérot oscillations.

Generative Ai for Cardiovascular Cell Type‐Specific Fluorescence Colorization of Live‐Cell hPSC‐Derived Cardiac Organoids

Advanced Intelligent Discovery, EarlyView.
A generative AI system is developed for colorizing phase contrast images of human pluripotent stem cell (hPSC)‐derived cardiac organoids (COs) from bright‐field microscopic imaging using conditional generative adversarial networks (cGANs). By giving these phase contrast images with multichannel fluorescence colorization, this intelligence system ...
