| 1 | Developing the Science Product Algorithm Testbed for Chinese Next-Generation Geostationary Meteorological Satellites:Fengyun-4 Series显示文摘Fengyun-4A(FY-4A), the first of the Chinese next-generation geostationary meteorological satellites, launched in2016, offers several advances over the FY-2: more spectral bands, faster imaging, and infrared hyperspectral measurements. To support the major objective of developing the prototypes of FY-4 science algorithms, two science product algorithm testbeds for imagers and sounders have been developed by the scientists in the FY-4 Algorithm Working Group(AWG). Both testbeds, written in FORTRAN and C programming languages for Linux or UNIX systems, have been tested successfully by using Intel/g compilers. Some important FY-4 science products, including cloud mask, cloud properties, and temperature profiles, have been retrieved successfully through using a proxy imager, Himawari-8/Advanced Himawari Imager(AHI), and sounder data, obtained from the Atmospheric Infra Red Sounder, thus demonstrating their robustness. In addition, in early 2016, the FY-4 AWG was developed based on the imager testbed—a near real-time processing system for Himawari-8/AHI data for use by Chinese weather forecasters.Consequently, robust and flexible science product algorithm testbeds have provided essential and productive tools for popularizing FY-4 data and developing substantial improvements in FY-4 products. | Min MIN Chunqiang WU Chuan LI Hui LIU Na XU Xiao WU Lin CHEN Fu WANG Fenglin SUN Danyu QIN Xi WANG Bo LI Zhaojun ZHENG Guangzhen CAO Lixin DONG | 2017 | Journal of Meteorological Research2017，31，4： | 35 |

| 4 | On-the-fly active learning of interpretable Bayesian force fields for atomistic rare events显示文摘Machine learned force fields typically require manual construction of training sets consisting of thousands of first principles calculations,which can result in low training efficiency and unpredictable errors when applied to structures not represented in the training set of the model.This severely limits the practical application of these models in systems with dynamics governed by important rare events,such as chemical reactions and diffusion.We present an adaptive Bayesian inference method for automating the training of interpretable,low-dimensional,and multi-element interatomic force fields using structures drawn on the fly from molecular dynamics simulations.Within an active learning framework,the internal uncertainty of a Gaussian process regression model is used to decide whether to accept the model prediction or to perform a first principles calculation to augment the training set of the model.The method is applied to a range of single-and multi-element systems and shown to achieve a favorable balance of accuracy and computational efficiency,while requiring a minimal amount of ab initio training data.We provide a fully opensource implementation of our method,as well as a procedure to map trained models to computationally efficient tabulated force fields. | Jonathan Vandermause Steven B.Torrisi Simon Batzner Yu Xie Lixin Sun Alexie M.Kolpak Boris Kozinsky | 2020 | npj Computational Materials2020，，1： | 17 |

| 6 | Discussion on the relationship between the Yanshanian Movement and cratonic destruction in North China显示文摘The relationship between the Yanshanian Movement, destruction of the North China Craton(NCC), and subduction of the western Pacific plate is crucial to reconstructing the middle-late Mesozoic tectonic evolution of the eastern Asian continent and margin. The Yanshanian Movement was a globally important change in crustal tectonics during the Middle-Late Jurassic.Previous research has systematically studied the formation and evolution of the Yanshanian Movement, focusing on the timing and location of tectonic movements, and the sedimentary and volcanic strata. However, the question of whether the tectonic activity occurred globally, and the characteristics of the Yanshanian Movement remain debated. The main argument is that if a tectonic movement can only be characterized by a regional or local disconformity, and if the tectonic movement occurred in an intracontinental setting, with extensive deformation but with no disconformity despite volcanic eruptions and magmatic intrusions, accompanied by changes in crustal structure and composition, should it be defined as a tectonic event or process? This question requires further analysis. The main aim of this study is to distinguish whether the Yanshanian Movement is a local feature of the eastern Asian continent, or a global tectonic event related to subduction of the Pacific Plate. In this paper, based on previous research, we discuss the spatial and temporal evolution of the Yanshanian Movement, the controlling tectonic mechanisms, and its relationship to the reactivation and destruction of the NCC and the subduction of the western Paleo-Pacific slab.We emphasize that the Yanshanian Movement in the Middle-Late Jurassic is distinct from the lithospheric thinning responsible for Early Cretaceous extension and magmatism related to the destruction of the NCC. The various tectonic stages were constrained by different dynamics and tectonic settings, or by different tectonic events and processes. Therefore, it is possible that the deformation and reactivation of the NCC contributed to its destruction, in addition to lithospheric thinning. Finally, we discuss whether the Yanshanian Movement was associated with the destruction of the NCC. | Yu WANG Lixin SUN Liyun ZHOU Yueting XIE | 2018 | Science China Earth Sciences2018，61，5： | 13 |
| 7 | Downwash distribution of single-rotor unmanned agricultural helicopter on hovering state显示文摘The effective coverage and velocity of downwash are directly related to the assemblage of spraying system and spraying effect.The downwash of the unmanned agricultural helicopter(UAH)N-3 was discussed in the paper.The computational fluid dynamics(CFD)methods were used to simulate and analyze the distribution of the downwash,and a wind field measurement device had been designed to test the downwash of UAH N-3.In the tests,the UAH N-3 was raised up to 5.0 m,6.0 m and 7.0 m from the ground,“annular-radial-distribution-point”method was introduced,8 directions separated by an angle of 45°(the radial direction)with the intersection point of the main rotor shaft and the ground plane as the center,0.5 m as the step length for the longitudinal(to 2.5 m)and radial(to 4.0 m)direction to set the sample points,considering the range of the rotor rotating circular area mainly.The 5 m height results of N-3 were fully discussed to describe the downwash distribution with the longitudinal altitude increased and the radial distance increased.The standard deviations of five test altitudes for eight directions were comparatively analyzed,the results showed that the total standard deviation was not greater than 0.6 m/s.The overall relative maximum margin of error calculated from the simulation and measurement data was between 0.6 and 0.7,which verified the credibility of the simulation data.High-order polynomials were used to fitting the simulation and measurement data,the fitting results showed that the polynomial coefficient of determination R^(2) met or exceeded 0.75 when the altitudes were more than 1 m,indicating the fit equation having the reference values.When the altitudes equal or less than 0.5 m,the polynomial coefficient of determination R^(2) was smaller,ranging during 0.3 to 0.7.The study would provide some foundations for the optimization of the assemblage of spraying system on the single-rotor UAH,which would promote China aviation plant protection. | Zhang Songchao Xue Xinyu Sun Zhu Zhou Lixin Jin Yongkui | 2017 | International Journal of Agricultural and Biological Engineering2017，10，5： | 13 |
| 8 | Discovery of carbonaceous compressions and their multicellular tissues from the Changzhougou Formation (1 800 Ma) in the Yanshan range, North China显示文摘In 1997 and 1998, hundreds of specimens of megascopic carbonaceous compressions or algal fossils were found from - 1800-million-year old Changzhougou Formation, which is the lowermost unit of the latest Palaeoproterozoic Changcheng Group (~1 600-1 800 Ma) in the Xinglong-Kuancheng areas at the middle Yanshan Range, North China. They are discoid, ellipsoid and sausage-like, namely shaped like Chuaria Shouhsiennia (Ellipsophyta) and Tawuia. By adopting HF acid-resistant maceration coupled with scanning electron microscope and petrologic section, the authors made a preliminary research on the histology for some circular and ellipsoid carbonaceous compressions, namely Chuaria- and Shouhsienia-llke forms, in addition to their morphology. The following three types of multicellular tissues have been found in the fragments of them: colony-like, pseudoparenchyma-like and parenchyma-like.

| 9 | An Arabidopsis ctpA homologue is involved in the repair of photosystem II under high light显示文摘A T-DNA insertion mutant AtctpA1 was identified to study the physiological roles of a carboxyl-terminal processing protease (CtpA) homologue in Arabidopsis. Under normal growth conditions, disruption of AtctpA1 did not result in any apparent alterations in growth rate and thylakoid membrane protein components. However the mutant plants exhibited increased sensitivity to high irradiance. Degradation of PSII reaction center protein D1 was accelerated in the mutant during photoinhibition. These results demostrated that AtctpA1 was required for efficient repair of PSII in Arabidopsis under high irradiance. | YIN ShuMing SUN XuWu ZHANG LiXin | 2008 | Chinese Science Bulletin2008，53，7： | 6 |
| 10 | Involvement of DEG5 and DEG8 proteases in the turnover of the photosystem II reaction center D1 protein under heat stress in Arabidopsis thaliana显示文摘Deg5,deg8 and the double mutant,deg5deg8 of Arabidopsis thaliana were used to study the physiological role of the DEG proteases in the repair cycle of photosystem II (PSII) under heat stress. PSII activity in deg mutants showed increased sensitivity to heat stress, and the extent of this effect was greater in the double mutant, deg5deg8, than in the single mutants, deg5 and deg8. Degradation of the D1 protein was slower in the mutants than in the WT plants. Furthermore, the levels of other PSII reaction center proteins tested remained relatively stable in the mutant and WT plants following high-temperature treatment. Thus, our results indicate that DEG5 and DEG8 may have synergistic function in degradation of D1 protein under heat stress. | SUN XuWu WANG LiYuan ZHANG LiXin | 2007 | Chinese Science Bulletin2007，52，13： | 6 |
| 11 | Self-starting passively mode-locked all fiber laser based on carbon nanotubes with radially polarized emission显示文摘We demonstrate an all fiber passively mode-locked laser emitting a radially polarized beam by using a few-mode fiber Bragg grating to achieve mode selection and spectrum filtering. An offset splicing of single-mode fiber with four-mode fiber is utilized as a mode coupler in the laser cavity. Carbon nanotubes are introduced into the laser cavity as the saturable absorber to achieve self-start mode locking. The laser operates at 1547.5 nm with a narrow spectrum width of 0.3 nm at 30 d B. The emitted mode-locked pulses have a duration of 22.73 ps and repetition of10.61 MHz. A radially polarized beam has been obtained with high mode purity by adjusting the polarization in the laser cavity. | Yong Zhou Jian Lin Xiaoqiang Zhang Lixin Xu Chun Gu Biao Sun Anting Wang Qiwen Zhan | 2016 | Photonics Research2016，4，6： | 6 |
| 12 | Integrating full-length transcriptomics and metabolomics reveals the regulatory mechanisms underlying yellow pigmentation in tree peony(Paeonia suffruticosa Andr.)flowers显示文摘Tree peony(Paeonia suffruticosa Andr.)is a popular ornamental plant in China due to its showy and colorful flowers.However,yellow-colored flowers are rare in both wild species and domesticated cultivars.The molecular mechanisms underlying yellow pigmentation remain poorly understood.Here,petal tissues of two tree peony cultivars,“High Noon”(yellow flowers)and“Roufurong”(purple–red flowers),were sampled at five developmental stages(S1–S5)from early flower buds to full blooms.Five petal color indices(brightness,redness,yellowness,chroma,and hue angle)and the contents of ten different flavonoids were determined.Compared to“Roufurong,”which accumulated abundant anthocyanins at S3–S5,the yellow-colored“High Noon”displayed relatively higher contents of tetrahydroxychalcone(THC),flavones,and flavonols but no anthocyanin production.The contents of THC,flavones,and flavonols in“High Noon”peaked at S3 and dropped gradually as the flower bloomed,consistent with the color index patterns.Furthermore,RNA-seq analyses at S3 showed that structural genes such as PsC4Hs,PsDFRs,and PsUFGTs in the flavonoid biosynthesis pathway were downregulated in“High Noon,”whereas most PsFLSs,PsF3Hs,and PsF3’Hs were upregulated.Five transcription factor(TF)genes related to flavonoid biosynthesis were also upregulated in“High Noon.”One of these TFs,PsMYB111,was overexpressed in tobacco,which led to increased flavonols but decreased anthocyanins.Dual-luciferase assays further confirmed that PsMYB111 upregulated PsFLS.These results improve our understanding of yellow pigmentation in tree peony and provide a guide for future molecular-assisted breeding experiments in tree peony with novel flower colors. | Xiaoning Luo Daoyang Sun Shu Wang Sha Luo Yaqi Fu Lixin Niu Qianqian Shi Yanlong Zhang | 2021 | Horticulture Research2021，8，1： | 5 |

| 15 | Application of a Step-by-Step Fingerprinting Identification Method on a Spilled Oil Accident in the Bohai Sea Area显示文摘In recent years,oil spill accidents occur frequently in the marine area of China.Finding out the spilled oil source is a key step in the relevant investigation.In this paper,a step-by-step fingerprinting identification method was used in a spilled oil accident in the Bohai Sea in 2002.Advanced chemical fingerprinting and data interpretation techniques were used to characterize the chemical composition and determine the possible sources of two spilled oil samples.The original gas chromatography -flame ionization detec-tion (GC-FID) chromatogram of saturated hydrocarbons was compared.The gas chromatography-mass spectrometry (GC/MS) chromatograms of aromatic hydrocarbons terpane and sterane,n-alkane and poly-aromatic hydrocarbons (PAHs) were analyzed.The correlation analysis on diagnostic ratios was performed with Student’s t-test.It is found that the oil fingerprinting of the spilled oil (designated as sz1) from the polluted sand beach was identical with the suspected oil (designated as ky1) from a nearby crude oil refinery factory.They both showed the fingerprinting character of mixed oil.The oil fingerprinting of the spilled oil (designated as ms1) collected from the port was significantly different from oil ky1 and oil sz1 and was with a lubricating oil fingerprint character.The identification result not only gave support for the spilled oil investigation,but also served as an example for studying spilled oil accidents. | SUN Peiyan GAO Zhenhui CAO Lixin WANG Xinping ZHOU Qing ZHAO Yuhui LI Guangmei | 2011 | Journal of Ocean University of China2011，10，1： | 4 |

| 17 | Deg1 is involved in the degradation of the PsbO oxygen-evolving protein of photosystem Ⅱ in Arabidopsis显示文摘Deg1,a thylakoid lumen-localized protease,retains both chaperone and protease activities.The in vivo function of Deg1 has been shown to be involved not only in PSII assembly but also in the degradation of PSII reaction center protein D1.Here we used the transgenic plants with reduced Deg1 to examine whether the lumen-localized proteins are also the substrates of Deg1 in vivo.Our results showed that the transgenic plants accumulated degradation products of the PsbO protein while the levels of full-length PsbO were not affected.The PsbO degradation products could be efficiently degraded by the recombinant Deg1.These results suggest that Deg1 is involved in the degradation of the PsbO degradation fragments,but not in the initial cleavage event itself. | LI Jin SUN XuWu ZHANG LiXin | 2010 | Chinese Science Bulletin2010，55，27： | 4 |
| 18 | Four Methods to Estimate Minimum Miscibility Pressure of CO2-Oil Based on Machine Learning显示文摘Summary of main observation and conclusion CO2 flooding accounts for a considerable proportion in gas flooding.Using CO2 as a gas displacement agent is benefit for enhanced oil recovery(EOR),and the alleviation of the greenhouse effect by the permanent storage of CO2 in the crust.Minimum miscibility pressure(MMP)of CO2-oil is a key factor affecting EOR,which determines the yield and economic benefit of crude oil recovery.Therefore,it is of great importance to use fast,accurate and cheap prediction methods for MMP estimation.In the present study,to evaluate the reliability of four recently developed prediction models based on machine learning(i.e.,neural network analysis(NNA),genetic function approximation(GFA),multiple linear regression(MLR),partial least squares(PLS)),136 sets of data are selected for calculation via outlier analysis from 147 sets of data.Afterwards,we compared the four models with existing prediction models from the literature.The analysis of correlation coefficients and multiple error functions shows that the four models can solve the MMP prediction problem well,and the model using intelligent algorithm has a higher prediction accuracy than the simple linear model.Besides,intelligent methods based on similarity algorithm have little difference from each other.Finally,a sensitivity analysis was conducted. | Ding Li Xiangliang Li Yinghua Zhang Lixin Sun Shiling Yuan | 2019 | Chinese Journal of Chemistry2019，37，12： | 4 |
| 19 | Optimal trajectory and downlink power control for multi-type UAV aerial base stations显示文摘Unmanned Aerial Vehicles(UAVs)enabled Aerial Base Stations(UABSs)have been studied widely in future communications.However,there are a series of challenges such as interference management,trajectory design and resource allocation in the scenarios of multi-UAV networks.Besides,different performances among UABSs increase complexity and bring many challenges.In this paper,the joint downlink transmission power control and trajectory design problem in multi-type UABSs communication network is investigated.In order to satisfy the signal to interference plus noise power ratio of users,each UABS needs to adjust its position and transmission power.Based on the interactions among multiple communication links,a non-cooperative Mean-Field-Type Game(MFTG)is proposed to model the joint optimization problem.Then,a Nash equilibrium solution is solved by two steps:first,the users in the given area are clustered to get the initial deployment of the UABSs;second,the Mean-Field Q(MFQ)-learning algorithm is proposed to solve the discrete MFTG problem.Finally,the effectiveness of the approach is verified through the simulations,which simplifies the solution process and effectively reduces the energy consumption of each UABS. | Lixin LI Yan SUN Qianqian CHENG Dawei WANG Wensheng LIN Wei CHEN | 2021 | Chinese Journal of Aeronautics2021，34，9： | 4 |
| 20 | Comparative metabolic profiling of Vitis amurensis and Vitis vinifera during cold acclimation显示文摘Vitis amurensis is a wild Vitis plant that can withstand extreme cold temperatures.However,the accumulation of metabolites during cold acclimation(CA)in V.amurensis remains largely unknown.In this study,plantlets of V.amurensis and V.vinifera cv.Muscat of Hamburg were treated at 4℃ for 24 and 72 h,and changes of metabolites in leaves were detected by gas chromatography coupled with time-of-flight mass spectrometry.Most of the identified metabolites,including carbohydrates,amino acids,and organic acids,accumulated in the two types of grape after CA.Galactinol,raffinose,fructose,mannose,glycine,and ascorbate were continuously induced by cold in V.amurensis,but not in Muscat of Hamburg.Twelve metabolites,including isoleucine,valine,proline,2-oxoglutarate,and putrescine,increased in V.amurensis during CA.More galactinol,ascorbate,2-oxoglutarate,and putrescine,accumulated in V.amurensis,but not in Muscat of Hamburg,during CA,which may be responsible for the excellent cold tolerance in V.amurensis.The expression levels of the genes encodingβ-amylase(BAMY),galactinol synthase(GolS),and raffinose synthase(RafS)were evaluated by quantitative reverse transcription-PCR.The expression BAMY(VIT_02s0012 g00170)and RafS(VIT_05s0077 g00840)were primarily responsible for the accumulation of maltose and raffinose,respectively.The accumulation of galactinol was attributed to different members of GolS in the two grapes.In conclusion,these results show the inherent differences in metabolites between V.amurensis and V.vinifera under CA. | Fengmei Chai Wenwen Liu Yue Xiang Xianbin Meng Xiaoming Sun Cheng Cheng Guotian Liu Lixin Duan Haiping Xin Shaohua Li | 2019 | Horticulture Research2019，6，1： | 3 |
