Infant facial expression recognition is of great importance for early care, which can help parents and caregivers to identify the emotional state of infants. In this study, we propose an improved YOLOv8 model for infant facial expression recognition. Compared with traditional YOLOv8 model, following improvements have been proposed. First, the Swin Transformer V2 structure is introduced in the back...Show More
A novel multi-dimensional nanostructure constructed with three types of nano-building-block is used as electrochemical sensing material to detect trace dopamine which plays as neurotransmitter in body-fluids. For the multi-dimensional multi-level sensing nanostructure construction, nanosheet of graphene oxide (GO) is herein served as nano-substrate. By using hydrothermal method, ZnO nanowires are ...Show More
