| 2 | Reworking effects in the Holocene Zhuye Lake sediments:A case study by pollen concentrates AMS ^(14)C dating显示文摘Transported by wind and water,the relatively old sediments can deposit in the terminal lake of an inland drainage basin.The reworking effect can affect the lake sediments 14 C dating and explanations for proxies.The Zhuye Lake is the terminal lake of the Shiyang River Basin.Previous studies indicated that sediments in different locations of the lake basin showed different climatic change patterns.And then,some radiocarbon dates were inverted for some Late Pleistocene sections.Whether this phenomenon is related with the reworking effect? The pollen concentrates 14 C dating can avoid the reservoir effect,which is an ideal method for studying the reworking effect.In this study,we used the pollen concentrates as dating materials and dated five Holocene sections in the Zhuye Lake Basin.Based on the 14 C dates comparison between the pollen concentrates,organic matter,and shells,the pollen concentrates dates are relatively older than other dating materials.Based on the result,the reworking effect worked in the Zhuye Lake Basin during the Holocene;however,in different locations of the lake basin the reworking effects were in different levels.Furthermore,the Holocene lacustrine deposits were formed mostly during the early and middle Holocene.This study provided clues for reworking effect studies of other lakes in arid China. | LIYu WANG NaiAng LI ZhuoLun ZHANG ChengQi ZHOU XueHua | 2012 | Science China Earth Sciences2012，55，10： | 7 |

| 4 | Effects of Target and Distractor Saturations on the Cognitive Performance of an Integrated Display Interface显示文摘Color coding is often used to enhance decision quality in complex man-machine interfaces of integrated display systems. However, people are easily distracted by irrelevant colors and by the numerous data points and complex structures in the interface. Although an increasing number of studies are seriously focusing on the problem of achieving efficient color coding, few are able to determine the effects of target and distractor saturations on cognitive performance. To study the performances of target colors among distractors, a systematic experiment is conducted to assess the influence of high and low saturated targets on cognitive performance, and the affecting extent of different saturated distractors of homogeneous colors on targets. According to the analysis of the reaction time through the non-parametric statistical method, a calculation method of the cognitive performance of each color is proposed. Based on the calculation of the color differences and the accumulation of the reaction times, it is shown that with the different saturated distractors of homogeneous colors, the high saturated yellow targets perform better than the low saturated ones, and the green and blue targets have moderate performances. When searching for a singleton target placed on a black background, the color difference between the target and the distractor should be more than 20ΔE*ab units in the yellow saturation coding, whereas the color difference should be more than 40ΔE*ab units in the blue and green saturation coding. In addition, as regards saturation coding, the influence of the color difference between the target and the background on cognitive performance is greater than that of the color difference between the target and the distractor. Seemingly, the hue attribute determines whether the saturation difference between the target and the distractor affects the cognitive performance. Based on the experimental results, the simulation design of the instrument dials in a flight situation awareness interface is completed and tested. Simulation results show the feasibility of the method of choosing the target and distractor colors, and the proposed research provides the instruction for the color saturation design of the interface. | XUE Chengqi LI Jing WANG Haiyan NIU Yafeng | 2015 | Chinese Journal of Mechanical Engineering2015，28，1： | 7 |
| 5 | Effects of intermittent loading time and stress ratio on dwell fatigue behavior of titanium alloy Ti-6Al-4V ELI used in deep-sea submersibles显示文摘Different components of deep-sea submersibles,such as the pressure hull,are usually subjected to intermittent loading,dwell loading,and unloading during service.Therefore,for the design and reliability assessment of structural parts under dwell fatigue loading,understanding the effects of intermittent loading time on dwell fatigue behavior of the alloys is essential.In this study,the effects of the intermittent loading time and stress ratio on dwell fatigue behavior of the titanium alloy Ti-6 Al-4 V ELI were investigated.Results suggest that the dwell fatigue failure modes of Ti-6 Al-4 V ELI can be classified into three types,i.e.,fatigue failure mode,ductile failure mode,and mixed failure mode.The intermittent loading time does not affect the dwell fatigue behavior,whereas the stress ratio significantly affects the dwell fatigue life and dwell fatigue mechanism.The dwell fatigue life increases with an increase in the stress ratio for the same maximum stress,and specimens with a negative stress ratio tend to undergo ductile failure.The mechanism of dwell fatigue of titanium alloys is attribute to an increase in the plastic strain caused by the part of the dwell loading,thereby resulting in an increase in the actual stress of the specimens during the subsequent loading cycles and aiding the growth of the formed crack or damage,along with the local plastic strain or damage induced by the part of the fatigue load promoting the cumulative plastic strain during the dwell fatigue process.The interaction between dwell loading and fatigue loading accelerates specimen failure,in contrast to the case for individual creep or fatigue loading alone.The dwell fatigue life and cumulative maximum strain during the first loading cycle could be correlated by a linear relationship on the log–log scale.This relationship can be used to evaluate the dwell fatigue life of Ti alloys with the maximum stress dwell. | Chengqi Sun Yanqing Li Kuilong Xu Baotong Xu | 2021 | Journal of Materials Science & Technology2021，，18： | 7 |
| 6 | Early Holocene environment at a key location of the northwest boundary of the Asian summer monsoon: a synthesis on chronologies of Zhuye Lake, Northwest China显示文摘The intensified monsoon increases summer rainfall and creates wet conditions in the Asian summer monsoon region during the early Holocene. Along with millennial-scale changes of the monsoon intensity, it is still unclear whether the boundary of the monsoon region changes according to monsoon variability. Investigations into the early Holocene environment in monsoon marginal zones are crucial for understanding the monsoon boundary changes. Zhuye Lake is located at the northwest edge of the Asian summer monsoon, the northern Qilian Mountains, which are less affected by modern summer monsoon water vapor. Previous studies have reached different conclusions regarding the early Holocene climatic and environmental changes based on different dating methods(14C and OSL(optically stimulated luminescence)) and materials(shells, carbonate, pollen concentrates and bulk organic carbon). In this study, we synthesized 102 14C dates and 35 OSL dates from ten Holocene sedimentary sections and ten paleo-shorelines in the lake basin. A comparison between ages from different dating methods and materials generally shows that carbon reservoir effects are relatively slight in Zhuye Lake while the disordered chronologies are mainly related to the erosion processes and reworking effects. In addition, proxy data, including lithology, pollen, total organic carbon and carbonate, were collected from different sites of Zhuye Lake. According to the new synthesis, the early Holocene environment was relatively humid, associated with high runoff and lake water levels. The result indicates that the monsoon boundary moves to the north during the period of the intensified monsoon. A typical arid-area lake was formed during the mid-Holocene when carbonate accumulation and high organic matter contents were the main features of this period. The lake retreated strongly during the late Holocene, showing a drought trend. Overall, the lake evolution is generally consistent with the Holocene Asian summer monsoon change, showing the monsoon influence to monsoon marginal zones. | Yu LI NaiAng WANG ChengQi ZHANG Yue WANG | 2014 | Journal of Arid Land2014，6，5： | 6 |
| 7 | The m^(6)A methylome of SARS-CoV-2 in host cells显示文摘The newly identified Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2)has resulted in a global health emergency because of its rapid spread and high mortality.The molecular mechanism of interaction between host and viral genomic RNA is yet unclear.We demonstrate herein that SARS-CoV-2 genomic RNA,as well as the negative-sense RNA,is dynamically N6-methyladenosine(m^(6)A)-modified in human and monkey cells.Combined RIP-seq and miCLIP analyses identified a total of 8 m^(6)A sites at single-base resolution in the genome.Especially,epidemic strains with mutations at these identified m^(6)A sites have emerged worldwide,and formed a unique cluster in the US as indicated by phylogenetic analysis.Further functional experiments showed that m^(6)A methylation negatively regulates SARS-CoV-2 infection.SARS-CoV-2 infection also triggered a global increase in host m^(6)A methylome,exhibiting altered localization and motifs of m^(6)A methylation in mRNAs.Altogether,our results identify m^(6)A as a dynamic epitranscriptomic mark mediating the virus–host interaction. | Jun’e Liu Yan-Peng Xu Kai Li Qing Ye Hang-Yu Zhou Hanxiao Sun Xiaoyu Li Liu Yu Yong-Qiang Deng Rui-Ting Li Meng-Li Cheng Bo He Jia Zhou Xiao-Feng Li Aiping Wu Chengqi Yi Cheng-Feng Qin | 2021 | Cell Research2021，31，4： | 5 |

But with the enhancement of spatial resolution, some questions have arisen in the application of using traditional image processing and classification methods. Aiming for such questions, we studied the application of IKONOS very high resolution image (1 m) in Xiamen City on Urban Vegetation Cover Investigation and discussed the difference between the very high resolution image and traditional low spatial resolution image at classification, information abstraction etc. It is an advantageous test for the large-scale application of very high resolution data in the future. | CHENG Chengqi,Li Bin,MA Ting(Institute of Remote Sensing & GIS, Peking University, Beijing 100871, China) | 2003 | Journal of Geographical Sciences2003，13，3： | 4 |
| 9 | A genome-wide association study of early-maturation traits in upland cotton based on the CottonSNP8oK array显示文摘Genome-wide association studies(GWASs)efficiently identify genetic loci controlling traits at a relatively high resolution.In this study,variations in major early-maturation traits,including seedling period(SP),bud period(BP),flower and boll period(FBP),and growth period(GP),of 169 upland cotton accessions were investigated,and a GWAS of early maturation was performed based on a CottonSNP80K array.A total of49,650 high-quality single-nucleotide polymorphisms(SNPs)were screened,and 29 significant SNPs located on chromosomes A6,A7,A8,D1,D2,and D9,were repeatedly identified as associated with early-maturation traits,in at least two environments or two algorithms.Of these 29 significant SNPs,1,12,11,and 5 were related to SP,BP,FBP,and GP,respectively.Six peak SNPs,TM47967,TM13732,TM20937,TM28428,TM50283,and TM72552,exhibited phenotypic contributions of approximately 10%,which could allow them to be used for marker-assisted selection.One of these,TM72552,as well as four other SNPs,TM72554,TM72555,TM72558,and TM72559,corresponded to the quantitative trait loci previously reported.In total,274 candidate genes were identified from the genome sequences of upland cotton and were categorized based on their functional annotations.Finally,our studies identified Gh_D01G0340 and Gh_D01G0341 as potential candidate genes for improving cotton early maturity. | Chengqi Li YuanyuanWang Nijiang Ai Yue Li Jiafeng Song | 2018 | Journal of Integrative Plant Biology2018，60，10： | 3 |

| 12 | High-temperature failure mechanism and defect sensitivity of TC17 titanium alloy in high cycle fatigue显示文摘Crack initiation is an essential stage of fatigue process due to its direct effect on fatigue failure.However,for titanium alloys in high-temperature high cycle fatigue(HCF),the crack initiation mechanisms remain unclear and the understanding for the defect sensitivity is also lacking.In this study,a series of fatigue tests and multi-scale microstructure characterizations were conducted to explore the high-temperature failure mechanism,and the coupled effect of temperature and defect on TC17 titanium alloy in HCF.It was found that an oxygen-rich layer(ORL)was produced at specimen surface at elevated temperatures,and brittle fracture of ORL at surface played a critical role for surface crack initiation in HCF.Besides,internal crack initiation with nanograins at high temperatures was a novel finding for the titanium alloy.Based on energy dispersive spectroscopy,electron backscatter diffraction and transmission electron microscope characterizations,the competition between surface and internal crack initiations at high temperatures was related to ORL at surface and dislocation resistance in inner microstructure.The fatigue strengths of smooth specimens decreased at elevated temperatures due to the lower dislocation resistance.While the fatigue strengths of the specimens with defect were not very sensitive to the temperatures.Finally,a fatigue strength model considering the coupled effect of temperature and defect was proposed for TC17titanium alloy. | Gen Li Chengqi Sun | 2022 | Journal of Materials Science & Technology2022，，27： | 2 |
| 13 | Genome-wide Mapping of Cellular Protein–RNA Interactions Enabled by Chemical Crosslinking显示文摘RNA–protein interactions influence many biological processes. Identifying the binding sites of RNA-binding proteins(RBPs) remains one of the most fundamental and important challenges to the studies of such interactions. Capturing RNA and RBPs via chemical crosslinking allows stringent purification procedures that significantly remove the non-specific RNA and protein interactions. Two major types of chemical crosslinking strategies have been developed to date, i.e., UV-enabled crosslinking and enzymatic mechanism-based covalent capture. In this review, we compare such strategies and their current applications, with an emphasis on the technologies themselves rather than the biology that has been revealed. We hope such methods could benefit broader audience and also urge for the development of new methods to study RNA RBP interactions. | Xiaoyu Li Jinghui Song Chengqi Yi | 2014 | Genomics, Proteomics & Bioinformatics2014，12，2： | 1 |

| 15 | Epitranscriptomic technologies and analyses显示文摘RNA can interact with RNA-binding proteins(RBPs),mRNA,or other non-coding RNAs(ncRNAs)to form complex regulatory networks.High-throughput CLIP-seq,degradome-seq,and RNA-RNA interactome sequencing methods represent powerful approaches to identify biologically relevant ncRNA-target and protein-ncRNA interactions.However,assigning ncRNAs to their regulatory target genes or interacting RNA-binding proteins(RBPs)remains technically challenging.Chemical modifications to mRNA also play important roles in regulating gene expression.Investigation of the functional roles of these modifications relies highly on the detection methods used.RNA structure is also critical at nearly every step of the RNA life cycle.In this review,we summarize recent advances and limitations in CLIP technologies and discuss the computational challenges of and bioinformatics tools used for decoding the functions and regulatory networks of ncRNAs.We also summarize methods used to detect RNA modifications and to probe RNA structure. | Xiaoyu Li Qiao-Xia Liang Jin-Ran Lin Jinying Peng Jian-Hua Yang Chengqi Yi Yang Yu Qiangfeng Cliff Zhang Ke-Ren Zhou | 2020 | Science China(Life Sciences)2020，63，4： | 1 |
| 16 | Changes in plasma calcitonin gene-related peptide and serum neuron specific enolase in rats with acute cerebral ischemia after low-frequency electrical stimulation with different waveforms and intensities显示文摘Following acute cerebral ischemia in rats,plasma calcitonin gene-related peptide decreased and the level of serum neuron specific enolase and the volume of the infarction increased.Square-wave and triangular-wave electrical stimulation with low or high intensities could increase the plasma calcitonin gene-related peptide,decrease the serum neuron specific enolase and reduce the infarction volume in the brain in rats with cerebral ischemia.There was no significant difference between different wave forms and intensities.The experimental findings indicate that low-frequency electrical stimulation with varying waveforms and intensities can treat acute cerebral ischemia in rats. | Qiang Gao Yonghong Yang Shasha Li Jing He Chengqi He | 2011 | Neural Regeneration Research2011，6，28： | 1 |

| 18 | STGI:a spatio-temporal grid index model for marine big data显示文摘Marine big data are characterized by a large amount and complex structures,which bring great challenges to data management and retrieval.Based on the GeoSOT Grid Code and the composite index structure of the MongoDB database,this paper proposes a spatio-temporal grid index model(STGI)for efficient optimized query of marine big data.A spatio-temporal secondary index is created on the spatial code and time code columns to build a composite index in the MongoDB database used for the storage of massive marine data.Multiple comparative experiments demonstrate that the retrieval efficiency adopting the STGI approach is increased by more than two to three times compared with other index models.Through theoretical analysis and experimental verification,the conclusion could be achieved that the STGI model is quite suitable for retrieving large-scale spatial data with low time frequency,such as marine big data. | Tengteng Qu Lizhe Wang Jian Yu Jining Yan Guilin Xu Meng Li Chengqi Cheng Kaihua Hou Bo Chen | 2020 | Big Earth Data2020，4，4： | 1 |
| 19 | Identification of molecular markers linked to rice bacterial blight resistance genes from Oryza meyeriana显示文摘Y73 is a progeny of asymmetric somatic hybridization between Oryza sativa cv.Dalixiang and the wild rice species Oryza meyeriana.Inoculation with a range of strains of Xanthomonas oryzae pv.oryzae showed that Y73 had inherited a high level of resistance to rice bacterial blight(BB)from its wild parent.An F2 population of 7125 individuals was constructed from the cross between Y73 and a BB-susceptible cultivar IR24.After testing 615 SSR and STS markers covering the 12 rice chromosomes,186 markers were selected that showed polymorphism between Y73 and IR24.Molecular markers linked to the BB resistance genes in Y73 were scanned using the F2 population and the polymorphic markers.The SSR marker RM128 on chromosome 1,the STS marker R03D159 on chromosome 3 and the STS marker R05D104 on chromosome 5 were found to be linked to the rice BB resistance genes in Y73. | Jing WANG Chen CHENG Yanru ZHOU Yong YANG Qiong MEI Junmin LI Ye CHENG Chengqi YAN Jianping CHEN | 2015 | Frontiers of Agricultural Science and Engineering2015，2，3： | 1 |
| 20 | A two-year(2020–2021)observation of marine phycotoxins in phytoplankton in typical mariculture areas of East China Sea显示文摘To learn the marine phycotoxins(MPTs)contamination status in mariculture areas in the East China Sea(ECS),from May 2020 to October 2021,80 net-concentrated phytoplankton samples were collected from 12 stations in three typical areas with high incidence of red tides,namely,Gouqi Island,Sandu’ao-Lianjiang,and Zhangzhou-Dongshan Island in ECS,and MPTs of the samples were detected.Six types of toxins were detected in 24 samples from 9 stations.Lipophilic marine toxins(LMTs)were more common and diverse in these areas.Pectenotoxin 2(PTX2)was the main lipophilic marine toxin(LMT)in the concentrated phytoplankton samples and the occurrence showed seasonal differences from north to south.According to the potential risks of pectenotoxin(PTXs)to seafood safety,it is suggested to execute regular monitoring on PTXs in ECS and a mandatory standard should be formulated based on the comprehensive analysis of in-situ monitoring and lab research.Meanwhile,contamination risks of cyclic imine toxins in the north and domoic acid(DA)in the south of ECS should also be paid with attention to.Only 2 paralytic shellfish toxins(PSTs),N-sulfocarbamoyl toxin C2(C2),and decarbamoyl gonyatoxin 3(dcGTX3),were found from spring samples in the north of ECS.As the biggest mussel culture county of China,Gouqi Island showed higher toxin diversity and the toxin detection rate was higher than the other two areas.In Gouqi Island area,PSTs were a serious potential threat in spring,and LMTs instead of PSTs became the main risk in summer-autumn seasons.To ensure the safety of seafood and marine environmental health,it is recommended to conduct long-term targeted tracking and monitoring of MPTs in this and similar mariculture areas. | Xiaoqing TIAN Chengqi FAN Yunyu TANG Haiyan ZHANG Wei KANG Sha CHEN Chongbin LI Ya’nan LU | 2022 | Journal of Oceanology and Limnology2022，40，6： | 1 |
