1Decreased nitrous oxide emissions associated with functional microbial genes under bio-organic fertilizer application in vegetable fields显示文摘Bio-organic fertilizers enriched with plant growth-promoting microbes(PGPMs)have been widely used in crop fields to promote plant growth and maintain soil microbiome functions.However,their potential effects on N_(2)O emissions are of increasing concern.In this study,an in situ measurement experiment was conducted to investigate the effect of organic fertilizer containing Trichoderma guizhouense(a plant growth-promoting fungus)on soil N_(2)O emissions from a greenhouse vegetable field.The following four treatments were used:no fertilizer(control),chemical fertilizer(NPK),organic fertilizer derived from cattle manure(O),and organic fertilizer containing T.guizhouense(O+T,referring to bio-organic fertilizer).The abundances of soil N cycling-related functional genes(amoA)from ammonium-oxidizing bacteria(AOB)and archaea(AOA),as well as nirS,nirK,and nosZ,were simultaneously determined using quantitative PCR(qPCR).Compared to the NPK plot,seasonal total N_(2)O emissions decreased by 11.7%and 18.7%in the O and O+T plots,respectively,which was attributed to lower NH_(4)^(+)-N content and AOB amoA abundance in the O and O+T plots.The nosZ abundance was significantly greater in the O+T plot,whilst the AOB amoA abundance was significantly lower in the O+T plot than in the O plot.Relative to the organic fertilizer,bio-organic fertilizer application tended to decrease N_(2)O emissions by 7.9%and enhanced vegetable yield,resulting in a significant decrease in yield-scaled N_(2)O emissions.Overall,the results of this study suggested that,compared to organic and chemical fertilizers,bio-organic fertilizers containing PGPMs could benefit crop yield and mitigate N_(2)O emissions in vegetable fields.Yajun GENG Yiming YUAN Yingcheng MIAO Junzhang ZHI Mengyuan HUANG Yihe ZHANG Hong WANG Qirong SHEN Jianwen ZOU Shuqing LI 2021Pedosphere2021,31,2:7
2Super stable CsPbBr3@SiO2 tumor imaging reagent by stress-response encapsulation显示文摘Great photoelectric properties can herald the high potentials of CsPbBr3 nanocrystals(NCs)to function as the fluorescent probes for early tumor diagnosis.However,the intrinsic water vulnerability of CsPbBr3 NCs highly restricts their biomedical applications.To conquer this challenge,we herein introduce a nature inspired'stress-response'method to tightly encapsulate CsPbBr3 into SiO2 nano-shells that can dramatically improve the water stability of CsPbBr3@SiO2 nanoparticles for over 48 h.We further highlighted the advantageous features of CsPbBr3@SiO2 by using them as the fluorescent probes for CT26 tumor cell imaging with their high water stability,biocompatibility,and low cytotoxicity.Our work for the first time exhibited the potential of lead halide perovskite NCs for tumor diagnosis,and can highly anticipate the further in vivo biomedical applications that light up live cells.Wentao Song Yiming Wang Bing Wang Yingfang Yao Wenguang Wang Jinhui Wu Qing Shen Wenjun Luo Zhigang Zou 2020Nano Research2020,13,3:7
3Monitoring somatosensory evoked potentials in spinal cord ischemia-reperfusion injury显示文摘It remains unclear whether spinal cord ischemia-reperfusion injury caused by ischemia and other non-mechanical factors can be monitored by somatosensory evoked potentials.Therefore,we monitored spinal cord ischemia-reperfusion injury in rabbits using somatosensory evoked potential detection technology.The results showed that the somatosensory evoked potential latency was significantly prolonged and the amplitude significantly reduced until it disappeared during the period of spinal cord ischemia.After reperfusion for 30–180 minutes,the amplitude and latency began to gradually recover;at 360 minutes of reperfusion,the latency showed no significant difference compared with the pre-ischemic value,while the somatosensory evoked potential amplitude increased,and severe hindlimb motor dysfunctions were detected.Experimental findings suggest that changes in somatosensory evoked potential latency can reflect the degree of spinal cord ischemic injury,while the amplitude variations are indicators of the late spinal cord reperfusion injury,which provide evidence for the assessment of limb motor function and avoid iatrogenic spinal cord injury.Yiming Ji Bin Meng Chenxi Yuan Huilin Yang Jun Zou 2013Neural Regeneration Research2013,8,33:5
4The Global Landscape of SARS-CoV-2 Genomes, Variants, and Haplotypes in 2019nCoVR显示文摘On January 22,2020,China National Center for Bioinformation(CNCB)released the 2019 Novel Coronavirus Resource(2019nCoVR),an open-access information resource for the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).2019nCoVR features a comprehensive integration of sequence and clinical information for all publicly available SARS-CoV-2 isolates,which are manually curated with value-added annotations and quality evaluated by an automated in-house pipeline.Of particular note,2019nCoVR offers systematic analyses to generate a dynamic landscape of SARS-CoV-2 genomic variations at a global scale.It provides all identified variants and their detailed statistics for each virus isolate,and congregates the quality score,functional annotation,and population frequency for each variant.Spatiotemporal change for each variant can be visualized and historical viral haplotype network maps for the course of the outbreak are also generated based on all complete and high-quality genomes available.Moreover,2019nCoVR provides a full collection of SARS-CoV-2 relevant literature on the coronavirus disease 2019(COVID-19),including published papers from PubMed as well as preprints from services such as bioRxiv and medRxiv through Europe PMC.Furthermore,by linking with relevant databases in CNCB,2019nCoVR offers data submission services for raw sequence reads and assembled genomes,and data sharing with NCBI.Collectively,SARS-CoV-2 is updated daily to collect the latest information on genome sequences,variants,haplotypes,and literature for a timely reflection,making 2019nCoVR a valuable resource for the global research community.2019nCoVR is accessible at https://bigd.big.ac.cn/ncov/.Shuhui Song Lina Ma Dong Zou Dongmei Tian Cuiping Li Junwei Zhu Meili Chen Anke Wang Yingke Ma Mengwei Li Xufei Teng Ying Cui Guangya Duan Mochen Zhang Tong Jin Chengmin Shi Zhenglin Du Yadong Zhang Chuandong Liu Rujiao Li Jingyao Zeng Lili Hao Shuai Jiang Hua Chen Dali Han Jingfa Xiao Zhang Zhang Wenming Zhao Yongbiao Xue Yiming Bao 2020Genomics, Proteomics & Bioinformatics2020,18,6:4
5Response of grease film at low speeds under pure rolling reciprocating motion显示文摘Using an optical interferometric technique,the grease film distribution under a pure rolling reciprocating motion is observed on a ball‐disk test rig,to explore the transient response of grease,which is expected to fill the contact with thickener fiber and run for a long time under steady‐state conditions.It is found that the reciprocating motion reduces the accumulation of the thickener fiber gradually with time.The maximum film thickness forms around the stroke ends.After 1,000 working cycles,very severe starvation occurs so that either the central or minimum film thickness becomes nearly constant over one working period.Thus,the life of grease lubrication under a transient condition is far below that under steady‐state conditions.However,it is also found that by selecting a smaller stroke length,the thickener fiber spreads out in the contact instead of being removed from the contact at the 1,000th working period.When increasing the maximum entraining speed of the reciprocating motion to a certain value,during which the thickener fiber is not expected to accumulate under a steady‐state condition,severe starvation occurs very quickly,causing surface damage.Yiming HAN Jing WANG Shanshan WANG Qian ZOU Gary BARBER 2020Friction2020,8,1:3
6LIM domain proteins Pinch1/2 regulate chondrogenesis and bone mass in mice显示文摘The LIM domain-containing proteins Pinch1/2 regulate integrin activation and cell–extracellular matrix interaction and adhesion.Here,we report that deleting Pinch1 in limb mesenchymal stem cells(MSCs)and Pinch2 globally(double knockout;dKO)in mice causes severe chondrodysplasia,while single mutant mice do not display marked defects.Pinch deletion decreases chondrocyte proliferation,accelerates cell differentiation and disrupts column formation.Pinch loss drastically reduces Smad2/3 protein expression in proliferative zone(PZ)chondrocytes and increases Runx2 and Col10a1 expression in both PZ and hypertrophic zone(HZ)chondrocytes.Pinch loss increases sclerostin and Rankl expression in HZ chondrocytes,reduces bone formation,and increases bone resorption,leading to low bone mass.In vitro studies revealed that Pinch1 and Smad2/3 colocalize in the nuclei of chondrocytes.Through its C-terminal region,Pinch1 interacts with Smad2/3 proteins.Pinch loss increases Smad2/3 ubiquitination and degradation in primary bone marrow stromal cells(BMSCs).Pinch loss reduces TGF-β-induced Smad2/3 phosphorylation and nuclear localization in primary BMSCs.Interestingly,compared to those from single mutant mice,BMSCs from dKO mice express dramatically lower protein levels ofβ-catenin and Yap1/Taz and display reduced osteogenic but increased adipogenic differentiation capacity.Finally,ablating Pinch1 in chondrocytes and Pinch2 globally causes severe osteopenia with subtle limb shortening.Collectively,our findings demonstrate critical roles for Pinch1/2 and a functional redundancy of both factors in the control of chondrogenesis and bone mass through distinct mechanisms.Yiming Lei Xuekun Fu Pengyu Li Sixiong Lin Qinnan Yan Yumei Lai Xin Liu Yishu Wang Xiaochun Bai Chuanju Liu Di Chen Xuenong Zou Xu Cao Huiling Cao Guozhi Xiao 2020Bone Research2020,8,4:2
7Development of optical-thermal coupled model for phosphor-converted LEDs显示文摘In this review, first, we discussed the effect of phosphor features on optical properties by the software simulation in detail. A combination of these parameters: phosphor material, phosphor particle size and particle distribution, phosphor layer concentration, phosphor layer thickness, geometry, and location of the phosphor layer, will result in the final optical performance of the phosphor layer. Secondly, we introduced how to improve light extraction efficiency with various proposed methods. Thirdly, we summarized the thermal models to predict the phosphor temperature and the junction temperature. To stabilize the optical performance of phosphor-converted light emitting diodes (PC-LEDs), much effort has been made to reduce the junction temperature of the LED chips. The phosphor temperature, a critical reliability concern for PC-LEDs, should be attracted academic interest. Finally, we summed up optical-thermal coupled model for phosphors and summarized future optical- thermal issues exploring the light quality for LEDs. We foresee that optical-thermal coupled model for PC-LEDs should be paid more attention in the future.Xinglu QIAN Jun ZOU Mingming SHI Bobo YANG Yang LI Ziming WANG Yiming LIU Zizhuan LIU Fei ZHENG 2019Frontiers of Optoelectronics2019,12,3:2
8Synthesis and Biological Evaluation of Hydroxylcoumarin Derivatives as Antioxidant Agents显示文摘In this study, esculetin(1) was chosen as a lead compound and some structural modifications weredesigned to explore the antioxidant activities of esculetin derivatives. Meanwhile, a convenient method for selectivemethylation of catechol cournarins with different bases was developed. Furthermore, a few 5,7-dihydroxylcoumarinswere synthesized and 7-hydroxylcoumarins were employed in order to explore the potential structure-antioxidantactivity relationships. The antioxidant activities of these compounds were evaluated and compared with standardantioxidant Trolox by the 22'-diphenyl-l-picrylhydrazyl(DPPH) assay, 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulfonate)cation(ABTS+) assay and ferric reducing antioxidant power(FRAP) assay. The results show that the catechol group isthe key pharmacophore. Meanwhile, introducing electronegative groups at the C4 position of esculetin(1) mayenhance the antioxidative capacity, while introducing a group containing nitrogen as a hydrogen bond acceptor at theC8 position may slightly reduce the antioxidative capacity, Among them, the most powerful antioxidants are com-pounds 5 and 7, which exhibit higher antioxidant activity than esculetin(1) in all assays.CHEN Chen WANG Ping ZOU Liwei YANG Ling FAN Yiming HU Wenzhong GE Guangbo 2017Chemical Research in Chinese Universities2017,33,2:2

10Recent Advances of Monolithic All-Perovskite Tandem Solar Cells:From Materials to Devices显示文摘Organic-inorganic metal-halide perovskite solar cells(PerSCs)have achieved significant progresses due to their outstanding optoelectronic charac-teristics,and the power conversion efficiency(PCE)of single-junction PerSCs has been boosted from 3.8%to a certified 25.2%.However,the efficien-cy of single-junction cells is governed by the Shockley-Queisser(S-Q)radiative limit,and fabricating all-perovskite tandem solar cells is a particularly attractive method to break the S-Q limit.Since the bandgap of lead(Pb)-based mixed halide perovskite can be tuned from 1.55 eV to 2.3 eV,and the mixed tin(Sn)-Pb perovskites have bandgap of~1.2 eV,these perovskites become the best candidates for the front and rear subcells of all-perovskite tandem device,respectively.In this review,we firstly summarize the current development progresses of two-terminal(2-T)all-perovskite tandem so-lar cells.For further optimizing the device performance,the wide bandgap mixed halide perovskites for front subcell,mixed Sn-Pb narrow bandgap perovskites for rear subcell,and the interconnection layer(ICL)of 2-T tandem device are then discussed.This review aims to open a pathway to real-ize highly efficient all-perovskite tandem solar cells.Shan Jiang Yiming Bai Zongwen Ma Shengli Jin Chao Zou Zhao'ao Tan 2022Chinese Journal of Chemistry2022,40,7:2

13Phase Characteristic Analysis of Continuous Depth Air-Gun Source Wavelet显示文摘Air guns are important sources for marine seismic exploration. Far-field wavelet of air gun arrays, as a necessary parameter for pre-stack processing and source models, plays an important role during marine seismic data processing and interpretation. When an air gun fires, it generates a series of air bubbles. Similar to onshore seismic exploration, the water forms a plastic fluid near the bubble; the farther the air gun is located from the measurement, the more steady and more accurately represented the wavelet will be. In practice, hydrophones should be placed more than 100 m from the air gun; however, traditional seismic cables cannot meet this requirement. On the other hand, vertical cables provide a viable solution to this problem. This study uses a vertical cable to receive wavelets from 38 air guns and data are collected offshore Southeast Qiong, where the water depth is over 1000 m. In this study, the wavelets measured using this technique coincide very well with the simulated wavelets and can therefore represent the real shape of the wavelets. This experiment fills a technology gap in China.XING Lei LIU Huaishan ZHENG Xilai LIU Xueqin ZHANG Jin WANG Linfei ZOU Zhihui XU Yiming 2016Journal of Ocean University of China2016,15,5:1

17Accelerated testing for automated vehicles safety evaluation in cut-in scenarios based on importance sampling,genetic algorithm and simulation applications显示文摘Purpose–It would take billions of miles’field road testing to demonstrate that the safety of automated vehicle is statistically significantly higher than the safety of human driving because that the accident of vehicle is rare event.Design/methodology/approach–This paper proposes an accelerated testing method for automated vehicles safety evaluation based on improved importance sampling(IS)techniques.Taking the typical cut-in scenario as example,the proposed method extracts the critical variables of the scenario.Then,the distributions of critical variables are statistically fitted.The genetic algorithm is used to calculate the optimal IS parameters by solving an optimization problem.Considering the error of distribution fitting,the result is modified so that it can accurately reveal the safety benefits of automated vehicles in the real world.Findings–Based on the naturalistic driving data in Shanghai,the proposed method is validated by simulation.The result shows that compared with the existing methods,the proposed method improves the test efficiency by 35 per cent,and the accuracy of accelerated test result is increased by 23 per cent.Originality/value–This paper has three contributions.First,the genetic algorithm is used to calculate IS parameters,which improves the efficiency of test.Second,the result of test is modified by the error correction parameter,which improves the accuracy of test result.Third,typical high-risk cut-in scenarios in China are analyzed,and the proposed method is validated by simulation.Yiming Xu Yajie Zou Jian Sun 2018Journal of Intelligent and Connected Vehicles2018,1,1:1

20Research on the discrimination methods of algae based on the fluorescence excitation spectra显示文摘The excitation spectra of chlorophyll (Chl) fluorescence can be used to differentiate phytoplankton populations at phylum level in vivo and in situ within a few minutes.The investigated phytoplankton divisions (Dinophyta,Bacillariophyta,Chrysophyta,Cyanophyta,Cryptophyta,Chlorophyta) are each characterized by a specific composition of photosynthetic antenna pigments and,consequently,by a specific excitation spectrum of the Chl fluorescence.Norm excitation spectra (emission of 680 nm and excitation of 400–600 nm) of every division were obtained from several species per division by a F4500 fluorescence spectrophotometer.Fisher’s linear discriminant analysis of the norm spectra shows that the divisions could be discriminated.The discrimination method,established by multivariate linear regression and weighted least squares,was used to differentiate the phytoplankton samples cultured in the laboratory and samples collected from the Jiaozhao Bay at division level.The correctly discriminated samples were more than 94% for single algal species ones,more than 84% for simulatively mixed ones,more than 83% for real mixed ones and 100% for samples collected from the Jiaozhou Bay for the dominant species.The method for phytoplankton differentiation described here can be applied to routine checking by fluorescence spectrophotometer,and benefit the monitoring and supervision tasks related to phytoplankton populations in the marine environments.HU Xupeng SU Rongguo ZOU Weiming REN Shijun WANG Hongtao CHAI Xiaoping WANG Yiming 2010Acta Oceanologica Sinica2010,29,4:1
