| 1 | Amplitude of low-frequency fluctuations on Alzheimer’s disease with depression: evidence from resting-state fMRI显示文摘Background The prevalence of Alzheimer's disease(AD)comorbid with depression is common.However,the mechanisms of AD with depression remain unclear.Aims To investigate the regional alterations of brain activity of AD with depression in resting-state functional magnetic resonance imaging(rs-fMRI).Methods 154 patients with AD who met the inclusion criteria were recruited from the Zhejiang Provincial People’s Hospital from October 2014 to October 2016.According to whether the core symptoms of depression were present,patients were divided into two groups,22 patients with AD with depression(AD-D)and 52 patients with AD without depression(AD-nD).The amplitude of low frequency fluctuations(ALFF)was compared between two groups by performing independent-samples f-test.Results Compared with the AD-D group,increased ALFF values in the bilateral superior frontal gyrus,left middle frontal gyrus and left inferior frontal gyrus were observed in the AD-nD group.The brain activity in the AD-nD group in the bilateral superior frontal gyrus,left middle frontal gyrus and the left inferior frontal gyrus was higher than the AD-D group.Conclusions Resting-state brain functional alterations may be closely bound up with the pathophysiologic features of patients with AD with depressive symptoms. | Yuzhu Mu Yumei Li Qi Zhang Zhongxiang Ding Mei Wang Xingguang Luo Xiaoyun Guo Maosheng Xu | 2020 | General Psychiatry2020，33，4： | 1 |
| 2 | Highly Efficient Aligned Ion‑Conducting Network and Interface Chemistries for Depolarized All‑Solid‑State Lithium Metal Batteries显示文摘Improving the long-term cycling stability and energy density of all-solid-state lithium(Li)-metal batteries(ASSLMBs)at room temperature is a severe challenge because of the notorious solid–solid interfacial contact loss and sluggish ion transport.Solid electrolytes are generally studied as two-dimensional(2D)structures with planar interfaces,showing limited interfacial contact and further resulting in unstable Li/electrolyte and cathode/electrolyte interfaces.Herein,three-dimensional(3D)architecturally designed composite solid electrolytes are developed with independently controlled structural factors using 3D printing processing and post-curing treatment.Multiple-type electrolyte films with vertical-aligned micro-pillar(p-3DSE)and spiral(s-3DSE)structures are rationally designed and developed,which can be employed for both Li metal anode and cathode in terms of accelerating the Li+transport within electrodes and reinforcing the interfacial adhesion.The printed p-3DSE delivers robust long-term cycle life of up to 2600 cycles and a high critical current density of 1.92 mA cm^(−2).The optimized electrolyte structure could lead to ASSLMBs with a superior full-cell areal capacity of 2.75 mAh cm^(−2)(LFP)and 3.92 mAh cm^(−2)(NCM811).This unique design provides enhancements for both anode and cathode electrodes,thereby alleviating interfacial degradation induced by dendrite growth and contact loss.The approach in this study opens a new design strategy for advanced composite solid polymer electrolytes in ASSLMBs operating under high rates/capacities and room temperature. | Yongbiao Mu Shixiang Yu Yuzhu Chen Youqi Chu Buke Wu Qing Zhang Binbin Guo Lingfeng Zou Ruijie Zhang Fenghua Yu Meisheng Han Meng Lin Jinglei Yang Jiaming Bai Lin Zeng | 2024 | Nano-Micro Letters2024，16，5： | 0 |
| 3 | Unprecedent green macroalgae bloom:mechanism and implication to disaster prediction and prevention显示文摘Green macroalgae bloom(GMB),with the dominant species of Ulva prolifera,has regularly occurred since 2007 along the China coast.Although disaster prevention and control achieved favorable results in 2020,the satellite-observed GMB annual maximum coverage(AMC)rebounded sharply in 2021 to an unprecedented level.The reasons for this rebound and the significant interannual variability over past 15 years are still open questions.Here,by using long-term time-series(2007-2022)optical and Synthetic Aperture Radar satellite observations(1000+scenes),meteorological data and water quality statistics,the mechanism analysis was performed by exploring effects from natural factors and human activities.Two key determinants for AMC are successfully identified from numerous potential factors which are the macroalgae distribution in a key area(the Subei Shoal)during a critical period(from April to May 20)and the nutrient availability.Furthermore,by using these two parameters,a novel model for AMC prediction(R^(2)=0.87,p<0.01)is proposed and independently validated,which can reasonably explain the significant interannual variability(2014-2021)and agree well with the latest observation in 2022(percentage difference 12%).Finally,suggestions are proposed for future disaster prevention and alleviation.This work may aid future bloom prediction and management measure optimization. | Mengmeng Cao Xuyan Li Tingwei Cui Xinliang Pan Yan Li Yanlong Chen Ning Wang Yanfang Xiao Xingai Song Yuzhu Xu Runa A Bing Mu Song Qing Rongjie Liu Wenjing Zhao Yuhai Bao Jie Zhang Lan Wei | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
