| 2 | ASAF: altered spontaneous activity fingerprinting in Alzheimer’s disease based on multisite fMRI显示文摘Several monocentric studies have noted alterations in spontaneous brain activity in Alzheimer's disease (AD), although there is no consensus on the altered amplitude of low-frequency fluctuations in AD patients. The main aim of the present study was to identify a reliable and reproducible abnormal brain activity pattern in AD. The amplitude of local brain activity (AM), which can provide fast mapping of spontaneous brain activity across the whole brain, was evaluated based on multisite rs-fMRI data for 688 subjects (215 normal controls (NCs), 221 amnestic mild cognitive impairment (aMCI) 252 AD). Two-sample t-tests were used to detect group differences between AD patients and NCs from the same site. Differences in the AM maps were statistically analyzed via the Stouffer's meta-analysis. Consistent regions of lower spontaneous brain activity in the default mode network and increased activity in the bilateral hippocampus/parahippocampus, thalamus, caudate nucleus, orbital part of the middle frontal gyrus and left fusiform were observed in the AD patients compared with those in NCs.

| 3 | Stability Analysis of Information Spreading on SNS Based on Refined SEIR Model显示文摘Investigating the stability of information spreading over SNS helps to understand the principles inherent in the spreading behavior.This paper explores the mechanisms of information spreading including stifling mechanism,latent mechanism and forgetting mechanism,establishes a refined SEIR model,and builds the corresponding mean-field equations.The methods of the differential dynamics and the next generation matrix are used to calculate the equilibriums and the basic reproductive number,and the asymptotical stability of the network equilibriums are proved theoretically.Simulation experiments are carried out to analyze the effect of the spreading mechanisms on the information spreading process and the results support our conclusions. | WANG Chao HU Yuanping LIU Chengyuan LIU Zhihong MA Jianfeng | 2014 | China Communications2014，11，11： | 2 |
| 4 | Carbon isotopic record from Upper Devonian carbonates at Dongcun in Guilin, southern China, supporting the world- wide pattern of carbon isotope excursions during Frasnian-Famennian transition显示文摘Two positive d 13C excursions are presented in records from the Frasnian-Famennian (F-F) marine carbon-ate sediments in Europe, America, Africa, and Australia, having been considered as a worldwide pattern, and attrib-uted to enhanced organic carbon burial during the F-F biological mass extinction. However, this worldwide pattern has not been revealed from the well-deposited Late Devonian sequences in southern China. In this paper, a detailed inves-tigation has been made on the Late Devonian section at Dongcun, Guilin, southern China to constrain perturbations in d 13C of carbonates in the F-F deposited sequence. The result from this section also indicates two positive d 13C ex-cursions during the F-F transition. The first excursion with an amplitude of 1.5 occurred at the bottom of linguiformis Zone, later than the early excursion existing in the Late rhe-nana Zone of the Late Devonian profiles in other continents, especially, in central Europe. This difference has been ex-pected to be a result as conodont Palmatolepis linguiformis occurred earlier in southern China than other sites. The second excursion with an amplitude of 2.1 is located at the F-F boundary, same as the records from other continents. This result strongly supports the view that two carbon iso-tope positive excursions during the F-F transition are com-mon in carbonate sediments, resulting from worldwide in-creases of organic carbon burial intensity. | XU Bing GU Zhaoyan LIU Qiang WANG Chengyuan LI Zhenliang | 2003 | Chinese Science Bulletin2003，48，12： | 2 |

| 10 | High-rate CH_(4)-to-C_(2)H_(6) photoconversion enabled by Au/ZnO porous nanosheets under oxygen-free system显示文摘Photocatalytic CH_(4) coupling into high-valued C_(2)H_(6) is highly attractive,whereas the photosynthetic rate,especially under oxygen-free system,is still unsatisfying.Here,we designed the negatively charged metal supported on metal oxide nanosheets to activate the inert C-H bond in CH_(4)and hence accelerate CH_(4) coupling performance.As an example,the synthetic Au/ZnO porous nanosheets exhibit the C_(2)H_(6) photosynthetic rate of 1,121.6μmol g^(-1)_(cat)h^(-1)and the CH_(4) conversion rate of 2,374.6μmol g^(-1)_(cat)h^(-1) under oxygen-free system,2 orders of magnitude higher than those of previously reported photocatalysts.By virtue of several in situ spectroscopic techniques,it is established that the generated Au^(δ-)and O^-species together polarized the C-H bond,while the Au^(δ-)and O^-species jointly stabilized the CH_(3) intermediates,which favored the coupling of CH_(3) intermediate to photosynthesize C_(2)H_(6) instead of overoxidation into CO_(x).Thus,the design of dual active species is beneficial for achieving high-efficient CH_(4)-to-C_(2)H_(6) photoconversion. | Kai Zheng Xiaojing Zhang Jun Hu Chengbin Xu Juncheng Zhu Jing Li Mingyu Wu Shan Zhu Li Li Shumin Wang Yumei Lv Xin He Ming Zuo Chengyuan Liu Yang Pan Junfa Zhu Yongfu Sun Yi Xie | 2024 | Science China Chemistry2024，67，3： | 0 |
| 11 | A thermo-hydro-mechano-chemical formulation for modeling water transport around a ventilated tunnel in an argillaceous rock显示文摘Argillaceous rocks are being considered as potential host rocks for deep geological disposal. For the research work in DECOVALEX-2011, 5 participant research teams performed simulations of a laboratory drying test and a ventilation experiment for Mont Terri underground laboratory built in argillaceous rock formation. Our study starts with establishing a coupled thermo-hydro-mechano-chemical (THMC) processes model to simulate water transport in rock around the ventilated tunnel. Especially in this THMC formulation, a three-phase and two-constituent hydraulic model is introduced to simulate the processes which occur during tunnel ventilation, including desaturation/resaturation in the rock, phase change and air/rock interface, and to explore the Opalinus clay parameter set. It can be found that water content evolution is very sensitive to intrinsic permeability, relative permeability and capillary pressure in clay rock. Water loss from surrounding rock is sensitive to the change of permeability in clay which is induced by excavation damaged zone. Chemical solute transport in the rock near ventilation experiment tunnel is simulated based on the coupled THMC formulation. It can be estimated that chemical osmotic flow has little significance on water flow modeling. Comparisons between simulation results from 5 teams and experimental observations show good agreement. It increases the confidence in modeling and indicates that it is a good start for fully THMC understanding of the moisture transportation and mechanical behavior in argillaceous rock. | Chengyuan Zhang Xiaoyan Liu Quansheng Liu | 2013 | Journal of Rock Mechanics and Geotechnical Engineering2013，5，2： | 0 |
| 12 | Oil and Financial Cooperation between China and the Middle East显示文摘The situation of oil-producing countries in the Middle East Six OPEC members are in the Middle East: Saudi Arabia, Iraq, Iran, Kuwait, Qatar and the United Arab Emirates, all in the Persian Gulf. In addition, Oman, Syria, Bahrain and Yemen produce oil and gas. In recent years, Israel has also become a natural gas producer. Only three countries in the Middle East, Lebanon, Palestine and Jordan, produce less oil and gas. As a result, 80% of the countries in the Middle East produce oil and gas, which is very rare in other parts of the world. | Liu Chaoquan Li Zhen Shang Yanli Li Chengyuan | 2019 | China Oil & Gas2019，26，6： | 0 |
| 13 | Low-coordination environment design of single Co atoms for efficient CO_(2) photoreduction显示文摘Photocatalytic carbon dioxide(CO_(2))to carbon monoxide(CO)offers a promising way for both alleviating the greenhouse effect and meeting the industrial demand.Herein,we constructed a Co single-atom catalyst with intentional low-coordination environment design on porous ZnO(denoted as Co1/ZnO).Impressively,Co1/ZnO exhibited a remarkable activity with a CO yield rate of 22.25 mmol·g^(-1)·h^(-1) and a selectivity of 80.2%for CO_(2) photoreduction reactions under visible light.The incorporation of single Co atoms provided an additional photo-generated electron transfer channel,which suppressed the carrier recombination of photocatalysts.Moreover,the unsaturated Co active sites were capable to adsorb CO_(2) molecule spontaneously,thus facilitating the activation of CO_(2) molecule during CO_(2) reduction course. | Zhentao Ma Qingyu Wang Limin Liu Rong-Ao Zhang Qichen Liu Peigen Liu Lihui Wu Chengyuan Liu Yu Bai Yida Zhang Haibin Pan Xusheng Zheng | 2024 | Nano Research2024，17，5： | 0 |
| 14 | Shared Core Microbiome and Functionality of Key Taxa Suppressive to Banana Fusarium Wilt显示文摘Microbial contributions to natural soil suppressiveness have been reported for a range of plant pathogens and cropping systems.To disentangle the mechanisms underlying suppression of banana Panama disease caused by Fusarium oxysporum f.sp.cubense tropical race 4(Foc4),we used amplicon sequencing to analyze the composition of the soil microbiome from six separate locations,each comprised of paired orchards,one potentially suppressive and one conducive to the disease.Functional potentials of the microbiomes from one site were further examined by shotgun metagenomic sequencing after soil suppressiveness was confrmed by greenhouse experiments.Potential key antagonists involved in disease suppression were also isolated,and their activities were validated by a combination of microcosm and pot experiments.We found that potentially suppressive soils shared a common core community with relatively low levels of F.oxysporum and relatively high proportions of Myxococcales,Pseudomonadales,and Xanthomonadales,with five genera,Anaeromyxobacter,Kofleria,Plesiocystis,Pseudomonas,and Rhodanobacter being significantly enriched.Further,Pseudomonas was identified as a potential key taxon linked to pathogen suppression.Metagenomic analysis showed that,compared to the conducive soil,the microbiome in the disease suppressive soil displayed a significantly greater incidence of genes related to quorum sensing,biofilm formation,and synthesis of antimicrobial compounds potentially active against Foc4.We also recovered a higher frequency of antagonistic Pseudomonas isolates from disease suppressive experimental field sites,and their protective effects against banana Fusarium wilt disease were demonstrated under greenhouse conditions.Despite differences in location and soil conditions,separately located suppressive soils shared common characteristics,including enrichment of Myxococcales,Pseudomonadales,and Xanthomonadales,and enrichment of specific Pseudomonas populations with antagonistic activity against the pathogen.Moreover,changes in functional capacity toward an increase in quorum sensing,biofilm formation,and antimicrobial compound synthesizing involve in disease suppression. | Zongzhuan Shen Linda S.Thomashow Yannan Ou Chengyuan Tao Jiabao Wang Wu Xiong Hongjun Liu Rong Li Qirong Shen George A.Kowalchuk | 2023 | Research2023，，1： | 0 |
| 15 | Reproducible Abnormalities and Diagnostic Generalizability of White Matter in Alzheimer’s Disease显示文摘Alzheimer’s disease(AD)is associated with the impairment of white matter(WM)tracts.The current study aimed to verify the utility of WM as the neuroimaging marker of AD with multisite diffusion tensor imaging datasets[321 patients with AD,265 patients with mild cognitive impairment(MCI),279 normal controls(NC)],a unified pipeline,and independent site cross-validation.Automated fiber quantification was used to extract diffusion profiles along tracts.Random-effects meta-analyses showed a reproducible degeneration pattern in which fractional anisotropy significantly decreased in the AD and MCI groups compared with NC.Machine learning models using tract-based features showed good generalizability among independent site cross-validation.The diffusion metrics of the altered regions and the AD probability predicted by the models were highly correlated with cognitive ability in the AD and MCI groups.We highlighted the reproducibility and generalizability of the degeneration pattern of WM tracts in AD. | Yida Qu Pan Wang Hongxiang Yao Dawei Wang Chengyuan Song Hongwei Yang Zengqiang Zhang Pindong Chen Xiaopeng Kang Kai Du Lingzhong Fan Bo Zhou Tong Han Chunshui Yu Xi Zhang Nianming Zuo Tianzi Jiang Yuying Zhou Bing Liu Ying Han Jie Lu Yong Liu Multi-Center Alzheimer’s Disease Imaging(MCADI)Consortium | 2023 | Neuroscience Bulletin2023，39，10： | 0 |
| 16 | Providing Guaranteed Network Performance across Tenants:Advances,Challenges and Opportunities显示文摘The varied network performance in the cloud hurts application performance.This increases the tenant’s cost and becomes the key hindrance to cloud adoption.It is because virtual machines(VMs)belonging to one tenant can reside in multiple physical servers and communication interference across tenants occasionally occurs when encountering network congestion.In order to prevent such unpredictability,it is critical for cloud providers to offer the guaranteed network performance at tenant level.Such a critical issue has drawn increasing attention in both academia and industry.Many elaborate mechanisms are proposed to provide guaranteed network performance,such as guaranteed bandwidth or bounded message delay across tenants.However,due to the intrinsic complexities and limited capabilities of commodity hardware,the deployment of these mechanisms still faces great challenges in current cloud datacenters.Moreover,with the rapid development of new technologies,there are new opportunities to improve the performance of existing works,but these possibilities are not under full discussion yet.Therefore,in this paper,we survey the latest development of the network performance guarantee approaches and summarize them based on their features.Then,we explore and discuss the possibilities of using emerging technologies as knobs to upgrade the performance or overcome the inherent shortcomings of existing advances.We hope this article will help readers quickly Received:Apr.07,2020 Revised:Oct.23,2020 Editor:Haifeng Zheng understand the causes of the problems and serve as a guide to motivate researchers to develop innovative algorithms and frameworks. | Chengyuan Huang Jiao Zhang Tao Huang Yunjie Liu | 2021 | China Communications2021，18，2： | 0 |
| 17 | The Study of Helium Variations in Star Clusters Using China Space Station Telescope显示文摘The China Space Station Telescope(CSST)is a 2 m space-based optical-UV telescope.Its primary goal is to carry out a high-resolution photometric imaging survey of a 17,500 square degree sky area using the on board Survey Camera.With its wide field of view(1.1 square degrees)and a mosaic imager containing 640 million pixels,studying the different populations of stars within star clusters is highly feasible.The aim of this study is to assess the CSST's ability to distinguish between stellar populations with varying helium abundance levels,with the help of Modules for Experiments in Stellar Astrophysics.The results of the CSST's photometry for these different populations are presented by transferring the models into the CSST Survey Camera photometric system.The findings confirm that helium-enriched stellar populations will have unique patterns in the color-magnitude diagrams under the CSST photometric system,compared to normal stellar populations.The CSST,with its filters and wide field of view of the Survey Camera,provides a new avenue for the study of multiple populations in star clusters. | Xin Ji Licai Deng Yang Chen Chengyuan Li Chao Liu | 2023 | Research in Astronomy and Astrophysics2023，23，7： | 0 |
| 18 | Spatio-temporal variations of shallow seismic velocity changes in Salton Sea Geothermal Field,California in response to large regional earthquakes and long-term geothermal activities显示文摘We measure spatio-temporal variations of seismic velocity changes in Salton Sea Geothermal Field,California based on cross correlations of daily seismic traces recorded by a borehole seismic network from December 2007 to January 2014.We find clear co-seismic velocity reductions during the 2010 M 7.2 El Mayor–Cucapah,Mexico earthquake at~100 km further south,followed by long-term recoveries.The co-seismic reductions are larger with longer post-seismic recoveries in higher frequency bands,indicating that material damage and healing process mostly occurred in the shallow depth.In addition,the co-seismic velocity reductions are larger for ray paths outside the active fluid injection/extraction regions.The ray paths inside injection/extraction regions are associated with smaller co-seismic reductions,but subtle long-term velocity increases.We also build 3D transient water flow models based on monthly injection/extraction rates,and find correlations between several water flow parameters and co-seismic velocity reductions.We interpret the relative lack of co-seismic velocity changes within the geothermal region as unclogging of fracture network due to persistent fluid flows of geothermal production.The long-term velocity increase is likely associated with the ground water depletion and subsidence due to net production. | Chengyuan Zhang Zhigang Peng Xiaoyan Liu Chenyu Li | 2023 | Earthquake Research Advances2023，3，2： | 0 |
| 19 | Clinical efficacy of low-dose emetine for patients with COVID-19:a real-world study显示文摘Objective:Emetine,an isoquinoline alkaloid that is enriched at high concentrations in the lung,has shown potent in vitro activity against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).The aim of this study was to better understand the effectiveness of low-dose emetine for patients with coronavirus disease 2019(COVID-19).Methods:In this real-world study,63 patients with mild or common COVID-19 were recruited from Wuhan Fangcang Shelter Hospital and five COVID-19-designated hospitals in Anhui Province,China from February to March 2020.Thirty-nine patients from Wuhan Fangcang Shelter Hospital were assigned to a pragmatic randomized controlled clinical trial,and 24 patients from the 5 COVID-19-designated hospitals in Anhui Province underwent a real-world study.The medication course of emetine was less than 10 days.The main symptoms and adverse reactions of all patients were observed and recorded.The primary outcome measure was the time required for a negative SARS-CoV-2 RNA result or the negative result rate on day 10.Secondary outcomes included axillary temperature,transcutaneous oxygen saturation,and respiratory frequency recovery.The study was approved by the Ethics Committee of The First Affiliated Hospital of Anhui Medical University on February 20,2019(approval No.PJ2020-03-19)and was registered with the Chinese Clinical Trial Registry on February 20,2019(registration number:ChiCTR2000030022).Results:The oxygen saturation values were higher in the treatment group than in the control group on the first day after enrollment for patients treated at Fangcang Shelter Hospital.The axillary body temperature,respiratory rate,and oxygen saturation among patients in Fangcang Shelter Hospital were related to the time effect but not to the intervention measures.The respiratory rate and oxygen saturation of patients in the Anhui designated hospitals were related to the intervention measures but not to the time effect.The axillary body temperature of patients in Anhui designated hospitals was related to the time effect but not to the intervention measures.Conclusion:Our preliminary study shows that low-dose emetine combined with basic conventional antiviral drugs improves clinical symptoms in patients with mild and common COVID-19 without apparent adverse effects,suggesting that moderately increased doses of emetine may have good potential for treatment and prevention of COVID-19. | Song Fan Qi Zhen Cheng Chen Wenjun Wang Qibing Wu Huihui Ma Chengyuan Zhang Li Zhang Baojing Lu Huiyao Ge Liang Yong Bao Li Yafen Yu Weiwei Chen Yiwen Mao Guangbo Qu Li Su Aoli Wang Zhen Ding Haiwen Li Jin Zhang Yonglian Wang Yufeng Gao Xihai Xu Zhongming Zhu Jun Chen Long Zhang Hongqiang Liang Song Wu Meng Huang Quan Xia Ping Li Yehuan Sun Chaozhao Liang Wei Wei Qingsong Liu Liangdan Sun | 2021 | Journal of Bio-X Research2021，4，2： | 0 |
| 20 | Turbidity-adaptive underwater image enhancement method using image fusion显示文摘Clear,correct imaging is a prerequisite for underwater operations.In real freshwater environment including rivers and lakes,the water bodies are usually turbid and dynamic,which brings extra troubles to quality of imaging due to color deviation and suspended particulate.Most of the existing underwater imaging methods focus on relatively clear underwater environment,it is uncertain that if those methods can work well in turbid and dynamic underwater environments.In this paper,we propose a turbidity-adaptive underwater image enhancement method.To deal with attenuation and scattering of varying degree,the turbidity is detected by the histogram of images.Based on the detection result,different image enhancement strategies are designed to deal with the problem of color deviation and blurring.The proposed method is verified by an underwater image dataset captured in real underwater environment.The result is evaluated by image metrics including structure similarity index measure,underwater color image quality evaluation metric,and speeded-up robust features.Test results exhibit that the method can correct the color deviation and improve the quality of underwater images. | Bin HAN Hao WANG Xin LUO Chengyuan LIANG Xin YANG Shuang LIU Yicheng LIN | 2022 | Frontiers of Mechanical Engineering2022，17，3： | 0 |
