Impact of aerosols on terrestrial gross primary productivity in North China using an improved boreal ecosystem productivity simulator with satellite-based aerosol optical depth

open access: yesGIScience & Remote Sensing, 2020
Atmospheric aerosols can alter the direct and diffuse components of global solar radiation, which further influences terrestrial gross primary productivity (GPP) via photosynthesis.

Compression-based AODE Classifiers

open access: yes, 2012
We propose the COMP-AODE classifier, which adopts the compression-based approach [1] to average the posterior probabilities computed by different non-naive classifiers (SPODEs). COMP-AODE improves classification performance over the well-known AODE [10] model. COMP-AODE assumes a uniform prior over the SPODEs; we then develop the credal classifier COMP-

Synergistic Mn‐MOF Activation of Pistol Ribozymes for Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A Mn2+‐based metal–organic framework delivers a catalytic Pistol ribozyme for targeted PD‐L1 mRNA cleavage in tumor cells, with the released Mn2+ not only inducing immune activation in immune cells but also increasing the Pistol ribozyme catalytic activity.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

open access: yesAdvanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Spatio-Temporal Variation in AOD and Correlation Analysis with PAR and NPP in China from 2001 to 2017

open access: yesRemote Sensing, 2020
Atmospheric aerosols can elicit variations in how much solar radiation reaches the ground surface due to scattering and absorption, which may affect plant photosynthesis and carbon uptake in terrestrial ecosystems.
