Recommender systems usually make personalized recommendation with user-item interaction
ratings, implicit feedback and auxiliary information. Matrix factorization is the basic idea to …

The gastrointestinal tract represents the largest mucosal membrane surface in the human
body. The immune system in the gut is the first line of host defense against mucosal microbial …

We developed a simple non-hot-injection synthetic route that achieves in situ halide-passivated
PbS and PbSe quantum dots (QDs) and simplifies the fabrication of Pb-chalcogenide …

Imaging protocols for suspected scaphoid fractures among investigators and hospitals are
markedly inconsistent. We performed a systematic review and meta-analysis to assess and …

Wide occurrence of aquatic metal pollution has caused much attention. Biomonitoring offers
an appealing tool for the assessment of metal pollution in aquatic ecosystem. The …

Radioluminescent materials (scintillators) are widely applied in medical imaging, nondestructive
testing, security inspection, nuclear and radiation industries, and scientific research. …

Imagers that operate in the near-infrared region (wavelengths of 0.7–1.4 µm) are of use in
applications such as material sorting, machine vision and autonomous driving. However, such …

Self-trapped excitons (STEs) in metal halide materials are attracting an increasing level of
interest due to their unique light emission properties. Light emission from STEs in metal …

Colloidal quantum dots (QDs) are promising candidates for the next generation of photovoltaic
(PV) technologies. Much of the progress in QD PVs is based on using PbS QDs, partly …

We developed a layer-by-layer method of preparing PbE (E = S or Se) quantum dot (QD)
solar cells using metal halide (PbI 2 , PbCl 2 , CdI 2 , or CdCl 2 ) salts dissolved in …
