| 1 | Seasonal variation and source apportionment of organic and inorganic compounds in PM_(2.5) and PM_(10) particulates in Beijing,China显示文摘The distribution and source of the solvent-extractable organic and inorganic components in PM 2.5(aerodynamics equivalent diameter below 2.5 microns),and PM 10(aerodynamics equivalent diameter below 10 microns) fractions of airborne particles were studied weekly from September 2006 to August 2007 in Beijing.The extracted organic and inorganic compounds identified in both particle size ranges consisted of n-alkanes,PAHs(polycyclic aromatic hydrocarbons),fatty acids and water soluble ions.The potential emission sources of these organic compounds were reconciled by combining the values of n-alkane carbon preference index(CPI),%waxC n,selected diagnostic ratios of PAHs and principal component analysis in both size ranges.The mean cumulative concentrations of n-alkanes reached 1128.65ng/m3 in Beijing,74% of which(i.e.,831.7ng/m3) was in the PM 2.5 fraction,PAHs reached 136.45ng/m3(113.44ng/m3 or 83% in PM 2.5),and fatty acids reached 436.99ng/m3(324.41ng/m3 or 74% in PM 2.5),which resulted in overall enrichment in the fine particles.The average concentrations of SO42-,NO3-,and NH4+ were 21.3±15.2,6.1±1.8,12.5±6.1μg/m3 in PM 2.5,and 25.8±15.5,8.9±2.6,16.9±9.5μg/m3 in PM 10,respectively.These three secondary ions primarily existed as ammonium sulfate((NH4)2SO4),ammonium bisulfate(NH4HSO4) and ammonium nitrate(NH4NO3).The characteristic ratios of PAHs revealed that the primary sources of PAHs were coal combustion,followed by gasoline combustion.The ratios of stearic/palmitic acid indicated the major contribution of vehicle emissions to fatty acids in airborne particles.The major alkane sources were biogenic sources and fossil fuel combustion.The major sources of PAHs were vehicular emission and coal combustion. | Xingru Li Yuesi Wang Xueqing Guo Yingfeng Wang | 2013 | Journal of Environmental Sciences2013,25,4: | 34 |
| 2 | The HuangZaoSi Maize Genome Provides Insights into Genomic Variation and Improvement History of Maize显示文摘Maize is a globally important crop that was a classic model plant for genetic studies. Here, we report a 2.2 Gb draft genome sequence of an elite maize line, HuangZaoSi (HZS). Hybrids bred from HZS-improved lines (HILs) are planted in more than 60% of maize fields in China. Proteome clustering of six completed sequeneed maize genomes show that 638 proteins fall into 264 HZS-specific gene families with the majority of contributions from tandem duplication events. Resequencing and comparative analysis of 40 HZSrelated lines reveals the breeding history of HILs. More than 60% of identified selective sweeps were clustered in identity.by.descent conserved regions, and yield-related genes/QTLs were enriched in HZS characteristic selected regions. Furthermore, we dem on strated that HZS-specific family genes were not uniformly distributed in the genome but enriched in improvement/function.related genomic regions. This study provides an important and novel resource for maize genome research and expands our knowledge on the breadth of genomic variation and improvement history of maize. | Chunhui Li Wei Song Yingfeng Luo Shenghan Gao Ruyang Zhang Zi Shi Xiaqing Wang Ronghuan Wang Fengge Wang Jidong Wang Yanxin Zhao Aiguo Su Shuai Wang Xin Li Meijie Luo Shuaishuai Wang Yunxia Zhang Jianrong Ge Xinyu Tan Ye Yuan Xiaochun Bi Hang He Jianbing Yan Yuandong Wang Songnian Hu Jiuran Zhao | 2019 | Molecular Plant2019,12,3: | 15 |
| 3 | The study on the safety and efficacy of amnion graft for preventing the recurrence of moderate to severe intrauterine adhesions显示文摘Transcervical resection of adhesion(TCRA)is the standard treatment for the intrauterine adhesions,but the recurrence of adhesions is a tough problem for the gynecologist.In addition,the therapeutic strategy after TCRA about prevention of recurrence remains controversial especially for the patients with moderate to severe intrauterine adhesions(IUAs).Hence,we designed this study to explore the safety and efficacy of fresh amnion grafts for preventing the recurrence after TCRA for patients with moderate to severe IUAs.One hundred patients with moderate to severe IUAs who presented with a history of hypomenorrhea,amenorrhea and infertility were included in the study from January 2015 to December 2017.Patients were divided into amnion group(52 patients)and chitosan group(48 patients).Fresh amnion grafts or intrauterine injections of chitosan were administered after TCRA.Transvaginal ultrasonography(TVUS)and hysteroscopy were performed at the first and third month after the operation.The surgical procedures for all patients were completed successfully without relevant complications.In amnion group,8 patients exhibited relapse in the first month and 2 patients in three months after surgery;in chitosan group,23 women exhibited relapse in the first month and 18 patients in three months after surgery.Statistical analysis revealed that the recurrence rate of adhesion in amnion group was significantly lower than those of chitosan group in the first and three months after surgery(P1=0.000,P2=0.000).After TCRA,fresh amnion graft plays a significant role in preventing further adhesions than injections of chitosan. | Changjiang Li Aiqi Cai Congcong Sun Benyuan Wu Xinpei Chen Yanhua Mao Yingfeng Zhang Yating Gou Jie Yu Yuhan Wang Huanhuan Yu Jia Wang | 2020 | Genes & Diseases2020,7,2: | 11 |
| 4 | A human circulating immune cell landscape in aging and COVID-19显示文摘Age-associated changes in immune cells have been linked to an increased risk for infection.However,a global and detailed characterization of the changes that human circulating immune cells undergo with age is lacking.Here,we combined scRNA-seq,mass cytometry and sCATAC-seq to compare immune cell types in peripheral blood collected from young and old subjects and patients with COVID-19.We found that the immune cell landscape was reprogrammed with age and was characterized by T cell polarization from naive and memory cells to effector,cytotoxic,exhausted and reg-ulatory cells,along with increased late natural killer cells,age-associated B cells,inflammatory monocytes and age-associated dendritic cells.In addition,the expression of genes,which were implicated in coron-avirus susceptibility,was upregulated in a cell subtype-specific manner with age.Notably,COVID-19 promoted age-induced immune cell polarization and gene expression related to inflammation and cellular senes-cence.Therefore,these findings suggest that a dysreg-ulated immune system and increased gene expression associated with SARS-CoV-2 susceptibility may at least partially account for COVID-19 vulnerability in the elderly. | Yingfeng Zheng Xiuxing Liu Wenqing Le Lihui Xie He Li Wen Wen Si Wang Shuai Ma Zhaohao Huang Jinguo Ye Wen Shi Yanxia Ye Zunpeng Liu Moshi Song Weiqi Zhang Jing-Dong J.Han Juan Carlos lzpisua Belmonte Chuanle Xiao Jing Qu Hongyang Wang Guang-Hui Liu Wenru Su | 2020 | Protein & Cell2020,11,10: | 10 |
| 5 | The apricot(Prunus armeniaca L.)genome elucidates Rosaceae evolution and beta-carotenoid synthesis显示文摘Apricots,scientifically known as Prunus armeniaca L,are drupes that resemble and are closely related to peaches or plums.As one of the top consumed fruits,apricots are widely grown worldwide except in Antarctica.A high-quality reference genome for apricot is still unavailable,which has become a handicap that has dramatically limited the elucidation of the associations of phenotypes with the genetic background,evolutionary diversity,and population diversity in apricot.DNA from P.armeniaca was used to generate a standard,size-selected library with an average DNA fragment size of~20 kb.The library was run on Sequel SMRT Cells,generating a total of 16.54 Gb of PacBio subreads(N50=13.55 kb).The high-quality P.armeniaca reference genome presented here was assembled using long-read single-molecule sequencing at approximately 70×coverage and 171×Illumina reads(40.46 Gb),combined with a genetic map for chromosome scaffolding.The assembled genome size was 221.9 Mb,with a contig NG50 size of 1.02 Mb.Scaffolds covering 92.88%of the assembled genome were anchored on eight chromosomes.Benchmarking Universal Single-Copy Orthologs analysis showed 98.0%complete genes.We predicted 30,436 protein-coding genes,and 38.28%of the genome was predicted to be repetitive.We found 981 contracted gene families,1324 expanded gene families and 2300 apricot-specific genes.The differentially expressed gene(DEG)analysis indicated that a change in the expression of the 9-cis-epoxycarotenoid dioxygenase(NCED)gene but not lycopene beta-cyclase(LcyB)gene results in a lowβ-carotenoid content in the white cultivar“Dabaixing”.This complete and highly contiguous P.armeniaca reference genome will be of help for future studies of resistance to plum pox virus(PPV)and the identification and characterization of important agronomic genes and breeding strategies in apricot. | Fengchao Jiang Junhuan Zhang Sen Wang Li Yang Yingfeng Luo Shenghan Gao Meiling Zhang Shuangyang Wu Songnian Hu Haoyuan Sun Yuzhu Wang | 2019 | Horticulture Research2019,6,1: | 9 |

| 8 | Vehicle Detection Based on Visual Saliency and Deep Sparse Convolution Hierarchical Model显示文摘Traditional vehicle detection algorithms use traverse search based vehicle candidate generation and hand crafted based classifier training for vehicle candidate verification.These types of methods generally have high processing times and low vehicle detection performance.To address this issue,a visual saliency and deep sparse convolution hierarchical model based vehicle detection algorithm is proposed.A visual saliency calculation is firstly used to generate a small vehicle candidate area.The vehicle candidate sub images are then loaded into a sparse deep convolution hierarchical model with an SVM-based classifier to perform the final detection.The experimental results demonstrate that the proposed method is with 94.81% correct rate and 0.78% false detection rate on the existing datasets and the real road pictures captured by our group,which outperforms the existing state-of-the-art algorithms.More importantly,high discriminative multi-scale features are generated by deep sparse convolution network which has broad application prospects in target recognition in the field of intelligent vehicle. | CAI Yingfeng WANG Hai CHEN Xiaobo GAO Li CHEN Long | 2016 | Chinese Journal of Mechanical Engineering2016,29,4: | 4 |
| 9 | Kinetics and mechanisms of mitotic inheritance of DNA methylation and their roles in aging-associated methylome deterioration显示文摘Mitotic inheritance of the DNA methylome is a challenging task for the maintenance of cell identity.Whether DNA methylation pattern in different genomic contexts can all be faithfully maintained is an open question.A replication-coupled DNA methylation maintenance model was proposed decades ago,but some observations suggest that a replication-uncoupled maintenance mechanism exists.However,the capacity and the underlying molecular events of replication-uncoupled maintenance are unclear.By measuring maintenance kinetics at the single-molecule level and assessing mutant cells with perturbation of various mechanisms,we found that the kinetics of replication-coupled maintenance are governed by the UHRF1–Ligase 1 and PCNA–DNMT1 interactions,whereas nucleosome occupancy and the interaction between UHRF1 and methylated H3K9 specifically regulate replication-uncoupled maintenance.Surprisingly,replication-uncoupled maintenance is sufficiently robust to largely restore the methylome when replication-coupled maintenance is severely impaired.However,solo-WCGW sites and other CpG sites displaying aging-and cancer-associated hypomethylation exhibit low maintenance efficiency,suggesting that although quite robust,mitotic inheritance of methylation is imperfect and that this imperfection may contribute to selective hypomethylation during aging and tumorigenesis. | Xuan Ming Zhuqiang Zhang Zhuoning Zou Cong Lv Qiang Dong Qixiang He Yangyang Yi Yingfeng Li Hailin Wang Bing Zhu | 2020 | Cell Research2020,30,11: | 4 |
| 10 | Trajectory prediction of cyclist based on dynamic Bayesian network and long short-term memory model at unsignalized intersections显示文摘Cyclist trajectory prediction is of great significance for both active collision avoidance and path planning of intelligent vehicles.This paper presents a trajectory prediction method for the motion intention of cyclists in real traffic scenarios.This method is based on dynamic Bayesian network(DBN)and long short-term memory(LSTM).The motion intention of cyclists is hard to predict owing to potential large uncertainties.The DBN is used to infer the distribution of cyclists’intentions at intersections to improve the prediction time.The LSTM with encoder-decoder is used to predict the cyclists’trajectories to improve the accuracy of prediction.Therefore,the DBN and LSTM are adopted to guarantee prediction accuracy and improve the prediction time.The experiment results are presented to show the effectiveness of the predict strategies. | Hongbo GAO Hang SU Yingfeng CAI Renfei WU Zhengyuan HAO Yongneng XU Wei WU Jianqing WANG Zhijun LI Zhen KAN | 2021 | Science China(Information Sciences)2021,64,7: | 4 |
| 11 | LiPO_(2)F_(2) electrolyte additive for high-performance Li-rich cathode material显示文摘Li-rich layered oxide cathodes have received considerable attention because of the high operating potential and specific capacity. However, the structural instability and parasitic reactions at high potential cause severe degradation of the electrochemical performance. In our studies, the cycling stability of Li_(1.14)Ni_(0.133)Co_(0.133)Mn_(0.544)O_(2) cathode is improved with LiPO_(2)F_(2) electrolyte additive. After 500 cycles, the capacity retention is increased from 53.6% to 85% at 3 C by LiPO_(2)F_(2) modification. This performance is mainly attributed to the enhanced interfacial stability of the Li-rich cathode. Based on systematic characterization, LiPO_(2)F_(2) additive was found to promote a stable interface film on the cathode surface during the cycling and mitigates the interfacial side reactions. This study provides new insights for improving high-potential Li-rich layered oxide batteries. | Bing Jiang Jingru Li Bi Luo Qizhang Yan Hao Li Lehao Liu Lihua Chu Yingfeng Li Qiaobao Zhang Meicheng Li | 2021 | Journal of Energy Chemistry2021,30,9: | 3 |

| 13 | Numerical Simulation for Damping-Controlled Deployment of Z-Folded Inflatable Tube显示文摘The damping-controlled deployment technology of flexible Z-folded inflatable tube is one of the key technologies of space inflatable structures.Constraint failure between couple nodes is proposed to simulate the damping-controlled deployment.And the equation of constraint failure is established.Inflation process of Z-folded tube is simulated with control volume method.Compared with uncontrolled method,it is indicated that the new method can effectively solve the disordered deployment problem of the slender Z-folded inflatable tube.By analyzing the displacement of the apical of the folded tube with different constraint forces during deployment process,the concept of effective constraint force is proposed.In the effective region of constraint force,the folded tube deploys with little retraction and fluctuation.Otherwise,The flexible folded tube would deploy disorderly or even cannot deploy.The simulation method and numerical results have a theoretical and instructive significance to the research on the space inflatable structures. | Yu Li Zhan Yanan Shi Yingfeng Zhao Xiaoshun Liu Xin | 2017 | Transactions of Nanjing University of Aeronautics and Astronautics2017,34,4: | 2 |

| 15 | Excellent light-capture capability of trilobal SiNW for ultra-high JSC in single-nanowire solar cells显示文摘Single-.nanowire solar cells with a unique light-concentration property are expected to exceed the Shockley-Queisser limit.The architecture of single nanowire is an important factor to regulate its optical performance.We designed a trilobal silicon nanowire(SiNW)with two cquivalent scales that possesses superior light-absorption efficiency in the whole wavelength range and shows good tolerance for incident angle.The electric field distribution in this geometry is concentrated in the blade with small equivalent scale and pivot with large equivalent scale,respectively,in the short wavelength range and long wavelength range.Corresponding good light absorption of trilobal SiNW in the two wavelength ranges leads to stronger total light absorption capacity than that of cylindrical SiNW.Trilobal single nanowire solar cells can obtain a short-circuit current density(JSC)of 647 mA·cm^2,which provides a new choice for designing single nanowire with excellent light-capture capability. | ZHONGLIANG GAO GUILU Lin YUPENG ZHENG NA SANG YINGFENG LI LEI CHEN MEICHENG LI | 2020 | Photonics Research2020,8,6: | 2 |

| 17 | Comparative Study on the Properties of Inorganic Silicate and Organic Phenolic Prepolymer Modified Poplar Wood by Vacuum Cycle Pressurization显示文摘To enhance mechanical properties and improve flame retardancy and smoke suppression of fast-growing poplar wood in wood applications,the wood was impregnated and modified.An organic phenolic prepolymer and inorganic sodium silicate was used as contrasting impregnation modifiers and wood samples were impregnated by a bionic“respiration”method with alternating positive and negative pressure.The weight percentage gain,density increase ratio,mechanical properties(bending and compressive strength and hardness),and water absorption rate of inorganic and organic-impregnated modified poplar wood(IIMPW and OIMPW,respectively)were compared and these properties in IIMPW were found to be higher than those of OIMPW with the exception of the water absorption rate which was lower than the OIMPW.This was attributed to the superior absorption of sodium silicate that also improved the impregnation,reinforcement,and dimensional stability in the IIMPW.The chemical structure,crystalline structure,internal morphology,flame retardancy,smoke suppression,and thermal stability of IIMPW and OIMPW were characterized by FT-IR,XRD,SEM,CONE,and TGA.FT-IR and XRD results showed that,although IIMPW cellulose crystallinity reduced the most,more chemical bonds were come into being in IIMPW,which explained the better physical and mechanical properties of IIMPW.Compared with OIMPW,IIMPW had better flame retardant and smoke suppression performance. | Pengfei Guan Ping Li Yiqiang Wu Xingong Li Guangming Yuan Yingfeng Zuo | 2022 | Journal of Renewable Materials2022,10,9: | 2 |
| 18 | Preparation and Characterization of Phenolic Prepolymer Impregnated Chinese Fir by Cyclic Increasing-Pressure Method with Green and Efficient显示文摘The Chinese fir wood was impregnated using a cyclic increasingpressure method(CIPM)with phenolic prepolymers as the impregnating modifier.Unmodified Chinese fir and progressive increasing-pressure method(PIPM)impregnated Chinese fir were used as reference samples and were compared and analyzed.The product’s chemical structure,internal morphology,crystal structure,and heat resistance were characterized.The transversal and longitudinal sections showed better filling effects,so that it bore greater external loading and reduced the water storage space.CIPM infused more phenolic prepolymer into the Chinese fir.Not only producing more physical filling but also forming more hydrogen bond associations and chemical bond combinations.Compared with PIPM and unmodi-fied Chinese fir,the CIPM impregnated Chinese fir had better mechanical strength and water resistance.The cellulose chains in CIPM impregnated Chinese fir were more closely linked and their crystallinity were clearly improved.Changes in internal morphology and crystal structure explained the reason why the mechanical properties and water resistance of CIPM impregnated Chinese fir were improved significantly.This Chinese fir had lower thermal decomposition rates,higher decomposition residual rates,and smaller combustion flames,which confirmed that it possessed improved heat and fire resistance. | Yuan Zhang Ping Li Yiqiang Wu Guangming Yuan Xianjun Li Yingfeng Zuo | 2020 | Journal of Renewable Materials2020,8,11: | 2 |
