In this paper, we propose an attention pyramid method for person re-identification. Unlike conventional attention-based methods which only learn a global attention map, our attention pyramid exploits ...

DNA nanotechnology has recently provided a novel approach for developing safe, biocompatible, biodegradable, non-immunogenic, and non-toxic drug delivery systems. DNA nanostructures have numerous ...
