Respiratory‐Limbic Coupling via a Thalamic Circuit Alleviates Anxiety
Advanced Science, EarlyView.This study delineates a conserved preBötCGlu→PVT→CeA circuit that gates anxiety and respiration. Activation of this circuit is anxiolytic and respiratory‐stabilizing, while its inhibition has the opposite effect. Mechanistically, PVT exerts its anxiolytic action via a disinhibitory microcircuit: its inputs preferentially target CeL GABAergic neurons ...

智能科学与技术学报, 2019 近年来，机器艺术创作逐步得到了人们的重视和长足的发展，通过算法加工的作品，甚至纯粹由机器生成的作品越来越多地出现在人们的视野中。然而，这些作品在感官效果上与人类的艺术作品相去甚远，且不具备共情属性，因此难以被人类认可。与此同时，技术对艺术领域的冲击也引起了人们的担忧。针对目前机器和人在艺术创作中面临的技术问题和人机关系问题，提出了平行艺术理论体系。该体系旨在构建机器与人的伙伴关系，使人与机器在艺术创作中以平行的方式进行配合与协作。这也将为融合以人为主的情感关系与以机器为主的逻辑关系提供一个新思路。

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome
Advanced Science, EarlyView.By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...

Global deposition of total reactive nitrogen oxides from 1996 to 2014 constrained with satellite observations of NO2 columns [PDF]
, 2017 Reactive nitrogen oxides (NOy) are a major constituent of the nitrogen deposited from the atmosphere, but observational constraints on their deposition are limited by poor or nonexistent measurement coverage in many parts of the world.

Machine Learning‐Guided Engineering of Protein Phase Separation Properties in Immune Regulation
Advanced Science, EarlyView.PScalpel, a machine learning model integrating protein structure extraction, graph contrastive learning, and a genetic algorithm, guides the engineering of protein phase separation ability. It adopts transfer learning methods to provide predictive recommendations for protein phase separation ability changes through single amino acid mutations in a ...

智能科学与技术学报, 2021 光场是环境中光线的集合，对光场信息的采集、计算以及显示是极具挑战性的复杂问题。基于 ACP 的平行光场理论为解决此问题提供了一条新的有效途径。平行光场利用采集得到的实际物理世界的光场信息构建了增强的人工世界的光场，并且以采集得到的实际物理世界的光场信息为引导，在增强的人工世界的光场中进行光场实验，得到最优的光场采集方案或者显示虚实方案，最后通过平行执行的过程建立起物理世界的光场和人工世界的光场的联动优化，使整个系统成为闭环，实现智能的光场采集和显示，建立光场信息处理和应用的虚实结合的全新理论体系。
