| 1 | MATRIEX imaging:multiarea two-photon real-time in vivo explorer显示文摘Two-photon laser scanning microscopy has been extensively applied to study in vivo neuronal activity at cellular and subcellular resolutions in mammalian brains.However,the extent of such studies is typically confined to a single functional region of the brain.Here,we demonstrate a novel technique,termed the multiarea two-photon real-time in vivo explorer(MATRIEX),that allows the user to target multiple functional brain regions distributed within a zone of up to 12mm in diameter,each with a field of view(FOV)of ~200μm in diameter,thus performing two-photon Ca2+imaging with single-cell resolution in all of the regions simultaneously.For example,we demonstrate real-time functional imaging of single-neuron activities in the primary visual cortex,primary motor cortex and hippocampal CA1 region of mice in both anesthetized and awake states.A unique advantage of the MATRIEX technique is the configuration of multiple microscopic FOVs that are distributed in three-dimensional space over macroscopic distances(>1 mm)both laterally and axially but that are imaged by a single conventional laser scanning device.In particular,the MATRIEX technique can be effectively implemented as an add-on optical module for an existing conventional single-beam-scanning two-photon microscope without requiring any modification to the microscope itself.Thus,the MATRIEX technique can be readily applied to substantially facilitate the exploration of multiarea neuronal activity in vivo for studies of brain-wide neural circuit function with single-cell resolution. | Mengke Yang Zhenqiao Zhou Jianxiong Zhang Shanshan Jia Tong Li Jiangheng Guan Xiang Liao Bing Leng Jing Lyu Kuan Zhang Min Li Yan Gong Zhiming Zhu Junan Yan Yi Zhou Jian K Liu Zsuzsanna Varga Arthur Konnerth Yuguo Tang Jinsong Gao Xiaowei Chen Hongbo Jia | 2019 | Light(Science & Applications)2019，8，1： | 4 |
| 2 | Recovering unknown topology in a two-layer multiplex network:One layer infers the other layer显示文摘There have been increasing interests in studying multiplex dynamical networks recently.This paper focuses on topology identiflcation of two-layer multiplex networks with peer-to-peer interlayer couplings.For a two-layer network model in which different layers have different coupling patterns,we propose novel methods to recover unknown topological structure of one layer,using the information of the other layer known as a prior.The proposed methods make full use of the measured evolutional states of the multiplex network itself,and treat the layer with a known structure as an auxiliary layer which is designed to identify the unknown topological layer.Compared with the traditional synchronization-based identiflcation method,the proposed methods are in no need of constructing an additional auxiliary network to identify the unknown topological layer,and thus greatly reduce the cost of topology identiflcation.Finally,numerical simulations validate the effectiveness of the proposed methods. | LIU Hui SHANG ZhiCheng REN ZiYi LI Yan ZENG ZhiGang LU JunAn | 2022 | Science China(Technological Sciences)2022，65，7： | 1 |
| 3 | Effective strategies to promote Z(S)-scheme photocatalytic water splitting显示文摘Artificial Z(S)-scheme photocatalytic water splitting systems have attracted extensive attention due to their advantages such as wide light absorption range,high charge separation efficiency and strong carrier redox ability.However,it is still challenging to design and prepare Z(S)-scheme photocatalysts with low-cost and highly stability for efficiently photocatalytic overall water splitting using solar energy.This review mainly introduces various strategies to improve the photocatalytic water splitting performance of Z(S)-scheme systems.These strategies mainly focus on enhancing or extending the range of light absorption,promoting charge separation,and enhancing surface redox reaction in Z(S)-scheme systems.Finally,the main challenges of Z(S)-scheme photocatalytic water splitting systems and their future development directions are pointed out.This review would be beneficial to understanding the challenges and opportunities faced by the research field of Z(S)-scheme photocatalytic systems,and has important guiding significance for the development and utilization of high-performance Z(S)-scheme photocatalytic reaction system in the future. | Ye Yuan Junan Pan Weinan Yin Haoxuan Yu Fengshun Wang Weifeng Hu Longlu Wang Dafeng Yan | 2024 | Chinese Chemical Letters2024，35，3： | 0 |
| 4 | 一条空间导航的记忆环路显示文摘文章简介本研究具有相当的挑战性,很大程度上是由于很难使用标准的电生理和成像方法,在动物执行与空间记忆相关的任务时对通路的活动进行实时监测。课题组巧妙地使用光纤光度计,采用Morris水迷宫和八臂迷宫这两个经典的空间记忆行为学范式。 | Han Qin 付玲 Bo Hu Xiang Liao Jian Lu Wenjing He Shanshan Liang Kuan Zhang Ruijie Li Jiwei Yao Junan Yan Hao Chen Hongbo Jia Benedikt Zott Arthur Konnerth 谌小维 | 2019 | 科学新闻2019，0，2： | 0 |
