Abstract. Semantic segmentation of ground-based all-sky images (ASIs) can provide high-resolution cloud coverage information distinct types, applicable for meteorology-, climatology- and solar-energy-related applications. Since the shape appearance clouds is variable, there high similarity between a clear classification difficult. Therefore, most state-of-the-art methods focus on distinction cl...

Optical Responsive Nanomaterials In article number 2208561, Zhang, Zheng, and co-workers report that a self-encrypted all-optical memory with ultrahigh switching contrast is realized in Y2O3:Eu3+-Au. All-optical information revisable writing, reading, encryption re-writing are by change of light power. This study not only provides insight into the unique thermal response plasmon resonance compo...
