| 2 | Paleoclimate Modeling in China: A Review显示文摘This paper provides a review of paleoclimate modeling activities in China. Rather than attempt to cover all topics, we have chosen a few climatic intervals and events judged to be particularly informative to the international community. In historical climate simulations, changes in solar radiation and volcanic activity explain most parts of reconstructions over the last millennium prior to the industrial era, while atmospheric greenhouse gas concentrations play the most important role in the20 th century warming over China. There is a considerable model–data mismatch in the annual and boreal winter temperature change over China during the mid-Holocene [6000 years before present(ka BP)], while coupled models with an interactive ocean generally perform better than atmospheric models. For the Last Glacial Maximum(21 ka BP), climate models successfully reproduce the surface cooling trend over China but fail to reproduce its magnitude, with a better performance for coupled models. At that time, reconstructed vegetation and western Pacific sea surface temperatures could have significantly affected the East Asian climate, and environmental conditions on the Qinghai–Tibetan Plateau were most likely very different to the present day. During the late Marine Isotope Stage 3(30–40 ka BP), orbital forcing and Northern Hemisphere glaciation, as well as vegetation change in China, were likely responsible for East Asian climate change. On the tectonic scale,the Qinghai–Tibetan Plateau uplift, the Tethys Sea retreat, and the South China Sea expansion played important roles in the formation of the East Asian monsoon-dominant environment pattern during the late Cenozoic. | JIANG Dabang YU Ge ZHAO Ping CHEN Xing LIU Jian LIU Xiaodong WANG Shaowu ZHANG Zhongshi YU Yongqiang LI Yuefeng JIN Liya XU Ying JU Lixia ZHOU Tianjun YAN Xiaodong | 2015 | Advances in Atmospheric Sciences2015，32，2： | 12 |

| 4 | The Asian Subtropical Westerly Jet Stream in CRA-40, ERA5, and CFSR Reanalysis Data:Comparative Assessment显示文摘The Asian subtropical westerly jet(AWJ) exerts crucial influences on Eurasian continent weather and climate. This paper analyzes the advantages and limitations of CRA-40, which is China's first generation 40-yr(1979–2018) global atmosphere and land reanalysis product, in describing the characteristics of AWJ, compared with the ECMWF Reanalysis version 5(ERA5) and NCEP Climate Forecast System Reanalysis(CFSR). The results show a close agreement across the three reanalyses on the whole.(1) In terms of climatology, overall differences of 200-h Pa zonal wind across the three reanalyses are within ± 0.5 m s^(-1)(i.e., ± 2%). Large differences with maxima of ± 2 m s^(-1)(±5%) appear over the Iranian Plateau and south of the Tibetan Plateau in the mid–upper troposphere in winter.(2) For seasonal cycle, the position and intensity of the AWJ centers in the three reanalyses are highly consistent, with correlation coefficient over 0.98. But there are some discrepancies in the zonal shift of the western AWJ center during the transition season.(3) On the interannual timescale, intensity of all AWJ centers varies consistently among the three reanalyses, while larger differences appear in their meridional displacement, especially in the eastern AWJ center.(4)For long-term variations, the three reanalyses all present a significant northward movement of the westerly jet axis in winter, and a southward displacement over central Asia(40°–80°E) and a northward migration over East Asia(80°–110°E) in summer. Thus, this study has provided confidence that CRA-40 has comparable performance with ERA5 and CFSR in depicting the characteristics of AWJ. | Xiaojing YU Lixia ZHANG Tianjun ZHOU Jingwei LIU | 2021 | Journal of Meteorological Research2021，35，1： | 10 |
| 5 | Warming decreases photosynthates and yield of soybean [Glycine max(L.) Merrill] in the North China Plain显示文摘Understanding the responses of field crops such as soybean to climate warming is critical for economic development and adaptive management of food security. A field warming experiment was conducted using infrared heaters to investigate the responses of soybean phenology, photosynthetic characteristics, and yield to climate warming in the North China Plain. The results showed that 0.4 °C and 0.7 °C increases in soybean canopy air and soil temperature advanced anthesis stage by 3.8 days and shortened the length of entire growth stage by 4.5 days. Warming also decreased the leaf photosynthetic rate by 6.6% and 10.3% at the anthesis and seed filling stages, respectively, but increased the leaf vapor pressure deficit by 9.4%, 15.7%, and 14.1% at the anthesis, pod setting, and seed filling stages,respectively. However, leaf soluble sugar and starch were decreased by 25.6% and 20.5%,respectively, whereas stem soluble sugar was reduced by 12.2% at the anthesis stage under experimental warming. The transportation amount of leaf soluble sugar and contribution rate of transportation amount to seed weight were reduced by 58.2% and 7.7%, respectively,under warming. As a result, warming significantly decreased 100-seed weight and soybean yield by 20.8% and 45.0%, respectively. Our findings provide better mechanistic understanding of soybean yield response to climate warming and could be helpful for forecasting soybean yield under future climate warming conditions. | Lixia Zhang Lili Zhu Mengyang Yu Mingxing Zhong | 2016 | The Crop Journal2016，4，2： | 9 |

| 7 | Rescue of premature aging defects in Cockayne syndrome stem cells by CRISPR/Cas9-mediated gene correction显示文摘Cockayne syndrome(CS)is a rare autosomal recessive inherited disorder characterized by a variety of clinical features,including increased sensitivity to sunlight,progressive neurological abnormalities,and the appearance of premature aging.However,the pathogenesis of CS remains unclear due to the limitations of current disease models.Here,we generate integration-free induced pluripotent stem cells(iPSCs)from fibroblasts from a CS patient bearing mutations in CSB/ERCC6 gene and further derive isogenic genecorrected CS-iPSCs(GC-iPSCs)using the CRISPR/Cas9 system.CS-associated phenotypic defects are recapitulated in CS-iPSC-derived mesenchymal stem cells(MSCs)and neural stem cells(NSCs),both of which display increased susceptibility to DNA damage stress.Premature aging defects in CS-MSCs are rescued by the targeted correction of mutant ERCC6.We next map the transcriptomic landscapes in CS-iPSCs and GC-iPSCs and their somatic stem cell derivatives(MSCs and NSCs)in the absence or presence of ultraviolet(UV)and replicative stresses,revealing that defects in DNA repair account for CS pathologies.Moreover,we generate autologous GC-MSCs free of pathogenic mutation under a cGMP(Current Good Manufacturing Practice)-compliant condition,which hold potential for use as improved biomaterials for future stem cell replacement therapy for CS.Collectively,our models demonstrate novel disease features and molecular mechanisms and lay a foundation for the development of novel therapeutic strategies to treat CS. | Si Wang Zheying Min Qianzhao Ji Lingling Geng Yao Su Zunpeng Liu Huifang Hu Lixia Wang Weiqi Zhang Keiichiro Suzuiki Yu Huang Puyao Zhang Tie-Shan Tang Jing Qu Yang Yu Guang-Hui Liu Jie Qiao | 2020 | Protein & Cell2020，11，1： | 7 |
| 8 | The FGOALS climate system model as a modeling tool for supporting climate sciences:An overview显示文摘Climate system models are useful tools for understanding the interactions among the components of the climate system and predicting/projecting future climate change. The development of climate models has been a central focus of the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences(LASG/IAP) since the establishment of the laboratory in 1985. In China, many pioneering component models and fully coupled models of the climate system have been developed by LASG/IAP. The fully coupled climate system developed in the recent decade is named FGOALS(Flexible Global Ocean-Atmosphere-Land System Model). In this paper, an application-oriented review of the LASG/IAP FGOALS model is presented. The improved model performances are demonstrated in the context of cloud-radiation processes, Asian monsoon, ENSO phenomena, Atlantic Meridional Overturning Circulation(AMOC) and sea ice. The FGOALS model has contributed to both CMIP5(Coupled Model Intercomparison Project-phase 5) and IPCC(Intergovernmental Panel on Climate Change) AR5(the Fifth Assessment Report). The release of FGOALS data has supported the publication of nearly 500 papers around the world. The results of FGOALS are cited ~106 times in the IPCC WG1(Working Group 1) AR5. In addition to the traditional long-term simulations and projections, near-term decadal climate prediction is a new set of CMIP experiment, progress of LAGS/IAP in the development of nearterm decadal prediction system is reviewed. The FGOALS model has supported many Chinese national-level research projects and contributed to the national climate change assessment report. The crucial role of FGOALS as a modeling tool for supporting climate sciences is highlighted by demonstrating the model's performances in the simulation of the evolution of Earth's climate from the past to the future. | TianJun Zhou Bin Wang YongQiang Yu YiMin Liu WeiPeng Zheng LiJuan Li Bo Wu PengFei Lin Zhun Guo WenMin Man Qing Bao AnMin Duan HaiLong Liu XiaoLong Chen Bian He JianDong Li LiWei Zou XiaoCong Wang LiXia Zhang Yong Sun WenXia Zhang | 2018 | Earth and Planetary Physics2018，2，4： | 6 |

| 10 | Pigment analysis of a color-leaf mutant in Wandering Jew (Tradescantia fluminensis) irradiated by carbon ions显示文摘Many mutants of plant induced by heavy ion beam irradiation have been reported in recent years,but leaf anthocyan mutants induced by ion irradiation in evergreen were rarely found.In this study,a color-leaf mutant with purple leaves,stems and petals was isolated from clones of Wandering Jew irradiated by 95.8 MeV/u carbon ion beam.The concentration and histological distribution of leaf pigment were surveyed in wild type and mutant.In mutant,contents of total chlorophylls (Chl),chlorophyll a (Chl a),chlorophyll b (Chl b) and carotenoids (Car) decreased significantly,while concentration of the anthocyanins was 6.2-fold higher than that of wild type.Further composition analysis of anthocyanins by electrospray ionization mass spectrometry (ESI-MS) indicated that the purple pigmentation of leaves in mutant was caused by accumulation of petunidin anthocyanin.Microscopic examination showed that most petunidin anthocyanin accumulated in the lower epidermis,and little in vascular parenchyma of mutant,while there was no pigment in wild type.Meanwhile,in spongy parenchyma of mutant we observed little Chl,which the wild type abounds in.In conclusion,the color-leaf mutant of Wandering Jew induced by irradiation of carbon ions was improved in ornamental value,and it could be contribute to variation in level,component and distribution of foliar pigment.The possible mutation mechanisms were discussed. | HE Jinyu LU Dong YU Lixia LI Wenjian | 2011 | Nuclear Science and Techniques2011，22，2： | 4 |
| 11 | Synthesis of branched ZnO nanorods on various substrates via a wet-chemistry route显示文摘Well-defined branched ZnO nanorods were fabricated on various substrates by a facile wet-chemistry route using a chemical bath deposition method at relatively low temperature.The structure,morphology and properties of the as-synthesized material were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),UV-vis spectrometry and photoluminescence(PL)spectrometry.Based on these characterizations,the growth process and synthesis mechanism were discussed in detail in terms of a combination of coordination agent and alkaline medium of hexamethylenetetramine used in the solutions.The effect of incubation time,solution composition and supported substrates on morphologies and sizes of the nanorods were further investigated.Meanwhile,the optical properties of branched ZnO nanorods on Zn substrate were measured. | Xianming Hou Lixia Wang Bo Yu Feng Zhou Weimin Liu | 2010 | Particuology2010，8，5： | 3 |
| 12 | Impact of the Rainfall Intensity and Seepage on Slope Stability in Loess Plateau显示文摘In recent years,with the increase of traffic construction in mountainous areas in China,road slope traffic accidents have become more and more common.In addition,natural disasters such as landslides,collapses and subgrade settlements caused by rainfall,driving load,seasonal variation and groundwater distribution are frequent.In particular,rainfall is one of the most common factors leading to slope instability(landslide).Therefore,this paper proposes the seep module based on the application software Geo-studio,and analyzes the slope soil parameters and slope stability under five types of rainfall conditions:light rain(10 mm/d),moderate rain(25 mm/d),heavy rain(50 mm/d),rainstorm(100 mm/d),and torrential rain(250 mm/d).The critical safety factor under rainfall intensity is fitted with nonlinear curve by sine function.The results show that the fitting curve of rainfall intensity and safety factor on the upper slope is excellent.The residual points are evenly distributed in the belt area of±0.1,and the data basically conform to the nonlinear sine model,indicating that the curve plays an essential role in slope health diagnosis. | ZHANG Yu YANG Lixia HAN Bingbing WU Yajie | 2020 | Earthquake Research in China2020，34，4： | 3 |
| 13 | 64 × 64 GM-APD array-based readout integrated circuit for 3D imaging applications显示文摘Using the high sensitivity of the avalanche photodiode(APD) detector operated in the Geigermode(GM), an array readout integrated circuit(ROIC) comprising a two-segment time-to-digital converter(TDC) is employed for wide-dynamic time interval measurement, where a 1-bit low-segment TDC is implemented by discriminating a single-phase clock period. The proposed 64 × 64 GM-APD array ROIC fabricated using Taiwan semiconductor manufacturing company(TSMC) 0.18-μm complementary metal oxide semiconductor(CMOS) technology can operate at a maximum frequency of 500 MHz provided by an external phase-locked loop clock. The time resolution is reduced to < 1 ns along with a maximum range of4 μs; the differential non-linearity(DNL) and integral non-linearity(INL) are restricted to approximately-0.15 to 0.15 least significant bit(LSB) and-0.3 to 0.32 LSB, respectively; and the power consumption is490 mW under a frame rate of 20 kH z. The developed ROIC is successfully used in imaging applications in two different ways. | Jin WU Zhiming QIAN Yang ZHAO Xiangrong YU Lixia ZHENG Weifeng SUN | 2019 | Science China(Information Sciences)2019，62，6： | 2 |
| 14 | Elf-1和Ki-67在非小细胞肺癌中的表达及其相关性研究(英文)显示文摘Objective: Elf-1 is a member of the proto-oncogenes Ets-related transcription factor family and over-expressed in many human tumors, Ki-67 is an important nuclear antigen associated with cell proliferation. This study investigated the expression of Elf-1 and Ki-67 in non-small-cell lung cancer(NSCLC) and studied their correlation with the clinicopathological features. Methods: Tissue microarray from 64 cases lung cancer tissue and 10 cases normal lung tissue was constructed, immunohistochemical method was used to evaluate the protein expressions of Elf-1 and Ki-67, correlations of the expression of Elf-1 and Ki-67 to clinicopathological features of NSCLC were analyzed. Results: Expression of Elf-1 and Ki-67 in NSCLC tissues were significantly higher than in normal lung tissues(P < 0.05), the positive rate of Elf-1 and Ki-67 was 73.44% and 64.06% in NSCLC group, Overexpression of Elf-1 in NSCLC was significantly related to histopathological grading, different clinical staging and the intensity of ELF-1 expression was significantly higher in the group with lymph node metastasis than that without(P < 0.05). Overexpression of Ki-67 was also closely related to tumor differentiation, clinical stages and lymph node metastasis(P < 0.05). In addition positive correlation was found between the expressive intensity of Elf-1 and Ki-67(τ = 0.295, P = 0.018). Conclusion: The high expression and positive correlation of Elf-1 and Ki-67 in NSCLC suggest that they probably play a role in onset and progression of lung cancer, united detecting their expression could be used as an valuable molecular biological index for predicting the malignant behavior and early diagnosis of NSCLC. | Lijun Kong Yuan Yu Hengyun Yu Lisha Zhang Lixia Zhang Xuhan Wang Liqing Kong | 2014 | The Chinese-German Journal of Clinical Oncology2014，13，6： | 2 |

| 16 | 中国南亚热带土壤易分解有机碳和水稳性团聚体对造林的响应显示文摘造林被认为可以提高土壤碳稳定性并促进土壤碳累积。然而,实验结果差异很大,造林在提高土壤碳稳定性方面的作用仍存在争议。因此,在森林生态系统中不同土壤碳库对造林如何响应目前尚不清楚。基于此,本文对亚热带地区的尾叶桉林(Eucalyptus urophylla)、厚荚相思林(Acacia crassicarpa)、红锥林(Castanopsis hystrix)、10树种混交林和自然恢复草坡等5种不同林型的土壤碳组分进行了研究,评估其不同土层(0–10、10–20、20–40和40–60 cm)中的土壤易分解有机碳(容易被高锰酸钾氧化的有机碳ROC和土壤可溶性有机碳DOC)及土壤团聚体相关的碳对造林的响应。实验结果表明,造林(与自然恢复草坡比较)和林型并没有显著影响土壤ROC浓度,而自然恢复草坡土壤的DOC浓度在4个土层中均最高。0–10 cm土层中各径级的土壤团聚体其碳(C)浓度均是红锥林最高。此外,在任一土层中,林型对不同径级土壤水稳性团聚体比例的影响均不显著。但是土壤深度显著改变土壤团聚体的分布,0–20 cm土层主要为>0.25 mm粒径的团聚体,20–60 cm土层则是0.053–2 mm粒径的团聚体占主导。这些结果显示造林和林型影响土壤DOC和团聚体C,而且它们相比于ROC对造林的响应更为敏感。研究发现,与自然恢复相比,人工林降低了土壤DOC浓度,暗示它可能会减少土壤C的淋溶损失。此外,红锥林能够通过物理保护提高表土层中土壤碳的稳定性。本研究为关注土壤碳汇功能时的中国南亚热带地区造林树种选择提供了有价值的信息。 | Yuanqi Chen Yu Zhang Shiqin Yu Feng Li Suping Liu Lixia Zhou Shenglei Fu | 2021 | Journal of Plant Ecology2021，14，2： | 2 |
| 17 | Detection of Asymptomatic Carotid Artery Stenosis in High-Risk Individuals of Stroke Using a Machine-Learning Algorithm显示文摘Objective Asymptomatic carotid stenosis(ACS)is closely associated to the incidence of severe cerebrovascular diseases.Early identifying the individuals with ACS and its associated risk factors could be beneficial for primary prevention of stroke.This study aimed to investigate a machine-learning algorithm for the detection of ACS among high-risk population of stroke based on the associated risk factors.Methods A novel model of machine learning was utilized to screen the associated predictors of ACS based on 30 potential risk factors.The algorithm of this model adopted a random forest pattern based on the training data and then was verified using the testing data.All of the original data were retrieved from the China National Stroke Screening and Prevention Project(CNSSPP),including demographic,clinical and laboratory characteristics.The individuals with high risk of stroke were enrolled and randomly divided into a training group and a testing group at a ratio of 4:1.The identification of carotid stenosis by carotid artery duplex scans was set as the golden standard.The receiver operating characteristic(ROC)curve and the area under the curve(AUC)was used to evaluate the efficacy of the model in detecting ACS.Results Of 2841 high risk individual of stroke enrolled,326(11.6%)were diagnosed as ACS by ultrasonography.The top five risk fectors contributing to ACS in this model were identified as family history of dyslipidemia,high level of lowdensity lipoprotein cholesterol(LDL-c),low level of high-density lipoprotein cholesterol(HDL-c),aging,and low body. | Junxiong Yin Cheng Yu Lixia Wei Chuanyong Yu Hongxing Liu Mingyang Du Feng Sun Chongjun Wang Xiaoshan Wang | 2020 | Chinese Medical Sciences Journal2020，35，4： | 2 |

Three flames with different mass percentage of propane in the fuel blends of 0%, 10%, and 20% were studied. The combustion intermediates were identified by comparing the measured IEs with those values in literatures. Mole fraction profiles of the main species were compared among the three flames. The experimental results provide detailed data in understanding the combustion of n-heptane and n-heptane/propane blends in engine. They are also helpful in establishing and verifying the kinetic models. | YU Wu WEI LiXia MA ZhiHao HUANG ZuoHua YUAN Tao TIAN ZhenYu LI YuYang | 2009 | Chinese Science Bulletin2009，54，9： | 1 |
| 20 | The mechanism of a new type of modified clay controlling Phaeocystis globosa growth显示文摘Phaeocystis globosa is a harmful algal bloom(HAB)species worldwide.Using modified clay(MC)to control HABs and to mitigate their adverse effects is currently a commonly used method in China.In this paper,the effects of oxidized composite modified clay(OXI-MC)on P.globosa were studied from different perspectives.The results show that the OXI-MC could effectively remove P.globosa and inhibit both the growth of residual algal cells and the formation of new colonies.The P.globosa algal biomass removal efficiencies after 3 h reached 90%at a dose of 0.1 g/L,and the number of colonies with different particle sizes was greatly reduced.Compared with those of the control,the superoxide dismutase(SOD)activity,catalase(CAT)activity,and malondialdehyde(MDA)content of the residual algae significantly increased,indicating that OXI-MC caused oxidative stress in the algal cells.In addition,we evaluated the effects of OXI-MC on the photosynthesis of residual microalgae and found that the maximal photochemical efficiency of photosystem II(PSII)under dark adaptation(F v/F m)and actual photochemical efficiency of PSII(ФPSII)decreased,severely damaging the photosynthesis efficiency,implying that OXI-MC effected the photosynthesis system of P.globosa.The results of this study clarify that OXI-MC could remove the most of algal cells and break up the colonies of P.globosa by collision,flocculation,and releasing active substances,as well as inhibit effectively the growth and colony formation of residual P.globosa by causing oxidative stress,reducing photosynthesis activity,accelerating the degradation of polysaccharides,and inhibiting the formation of colonies. | QIU Lixia YU Zhiming CAO Xihua JI Hena SONG Xiuxian | 2020 | Journal of Oceanology and Limnology2020，38，4： | 1 |
