The challenge of unsupervised person re-identification (ReID) lies in learning discriminative
features without true labels. This paper formulates unsupervised person ReID as a multi-…

Strong blue fluorescent polyethylene glycol (PEG) anchored carbon nitride dots (CDs@PEG)
with a high quantum yield (QY) of 75.8% have been synthesized by a one step …

Carbon dots (CDs) have shown great potential in imaging and drug/gene delivery
applications. In this work, CDs functionalized with a nuclear localization signal peptide (NLS-CDs) …

Crowded scenes make it challenging to differentiate persons and locate their pose keypoints.
This paper proposes the Contextual Instance Decoupling (CID), which presents a new …

Exosomes have been extensively explored as delivery vehicles due to low immunogenicity,
efficient cargo delivery, and possibly intrinsic homing capacity. However, therapeutic …

The direct difunctionalization of alkenes has emerged as a sustainable and versatile
strategy for the efficient construction of complex molecules from simple chemical feedstocks. …

Agility and trajectory control are two desirable features for robotics, but they become very
challenging for soft robots without rigid structures to support rapid manipulations. Here, a …

Cancer immunotherapy has been a favorable strategy for facilitating antitumor immunity.
However, immune tolerance and an ultimate immunosuppressive tumor microenvironment (ITM…

The physical memory capacity of servers is expected to increase drastically with deployment
of the forthcoming non-volatile memory technologies. This is a welcomed improvement for …

Most of the newly developed drug candidates are lipophilic and poorly water-soluble.
Enhancing the dissolution and bioavailability of these drugs is a major challenge for the …
