| 1 | Source apportionment and secondary organic aerosol estimation of PM_(2.5) in an urban atmosphere in China显示文摘PM2.5 is the key pollutant in atmospheric pollution in China.With new national air quality standards taking effect,PM2.5 has become a major issue for future pollution control.To effectively prevent and control PM2.5,its emission sources must be precisely and thoroughly understood.However,there are few publications reporting comprehensive and systematic results of PM2.5 source apportionment in the country.Based on PM2.5 sampling during 2009 in Shenzhen and follow-up investigation,positive matrix factorization(PMF)analysis has been carried out to understand the major sources and their temporal and spatial variations.The results show that in urban Shenzhen(University Town site),annual mean PM2.5 concentration was 42.2μg m?3,with secondary sulfate,vehicular emission,biomass burning and secondary nitrate as major sources;these contributed30.0%,26.9%,9.8%and 9.3%to total PM2.5,respectively.Other sources included high chloride,heavy oil combustion,sea salt,dust and the metallurgical industry,with contributions between 2%–4%.Spatiotemporal variations of various sources show that vehicular emission was mainly a local source,whereas secondary sulfate and biomass burning were mostly regional.Secondary nitrate had both local and regional sources.Identification of secondary organic aerosol(SOA)has always been difficult in aerosol source apportionment.In this study,the PMF model and organic carbon/elemental carbon(OC/EC)ratio method were combined to estimate SOA in PM2.5.The results show that in urban Shenzhen,annual SOA mass concentration was 7.5μg m?3,accounting for 57%of total organic matter,with precursors emitted from vehicles as the major source.This work can serve as a case study for further in-depth research on PM2.5 pollution and source apportionment in China. | HUANG XiaoFeng YUN Hui GONG ZhaoHeng LI Xiang HE LingYan ZHANG YuanHang HU Min | 2014 | Science China Earth Sciences2014，57，6： | 28 |
| 2 | Rural land use spatial allocation in the semiarid loess hilly area in China:Using a Particle Swarm Optimization model equipped with multi-objective optimization techniques显示文摘Semiarid loess hilly areas in China are enduring a series of environmental conflicts between urban expansion,cultivated land conservation,soil erosion and water shortage,and require land use allocation to reconcile these environmental conflicts.We argue that the optimized spatial allocation of rural land use can be achieved by a Particle Swarm Optimization (PSO) model in conjunction with multi-objective optimization techniques.Our study focuses on Yuzhong County of Gangsu Province in China,a typical catchment on the Loess Plateau,and proposes a land use spatial optimization model.The model maximizes land use suitability and spatial compactness based on a variety of constraints,e.g.optimal land use structure and restrictive areas,and employs an improved PSO algorithm equipped with a determinant initialization method and a dynamic weighted aggregation (DWA) method to obtain the optimized land use spatial pattern.The results suggest that (1) approximately 4% of land use should be reallocated and these changes would alleviate the environmental conflicts in the study area;(2) the major reshuffling is slope farmland and newly added construction and cultivated land,whereas the unchanged areas are largely forests and basic farmland;and (3) the PSO is capable of optimizing rural land use allocation,and the determinant initialization method and DWA can improve the performance of the PSO. | LIU YaoLin LIU DianFeng LIU YanFang HE JianHua JIAO LiMin CHEN YiYun HONG XiaoFeng | 2012 | Science China Earth Sciences2012，55，7： | 23 |

| 5 | Understanding primary and secondary sources of ambient oxygenated volatile organic compounds in Shenzhen utilizing photochemical age-based parameterization method显示文摘Oxygenated volatile organic compounds(OVOCs) are key intermediates in the atmospheric photooxidation process. To further study the primary and secondary sources of OVOCs,their ambient levels were monitored using a proton-transfer reaction mass spectrometer(PTR-MS) at an urban site in the Pearl River Delta of China. Continuous monitoring campaigns were conducted in the spring, summer, fall, and winter of 2016. Among the six types of OVOC species, the mean concentrations of methanol were the highest in each season(up to 13–20 ppbv), followed by those of acetone, acetaldehyde and acetic acid(approximately 2–4 ppbv), while those of formic acid and methyl ethyl ketone(MEK) were the lowest(approximately 1–2 ppbv). As observed from a diurnal variation chart, the OVOCs observed in Shenzhen may have been affected by numerous factors such as their primary and secondary sources and photochemical consumption. The photochemical age-based parameterization method was used to apportion the sources of ambient OVOCs. Methanol had significant anthropogenic primary sources but negligible anthropogenic secondary sources during all of the seasons. Acetone, MEK and acetic acid were mostly attributed to anthropogenic primary sources during each season with smaller contributions from anthropogenic secondary sources. Acetaldehyde had similar contributions from both anthropogenic secondary and anthropogenic primary sources throughout the year.Meanwhile, anthropogenic primary sources contributed the most to formic acid. | Bo Zhu Yu Han Chuan Wang Xiaofeng Huang Shiyong Xia Yingbo Niu Zixuan Yin Lingyan He | 2019 | Journal of Environmental Sciences2019，31，1： | 13 |
| 6 | Event-Triggered Differentially Private Average Consensus for Multi-agent Network显示文摘This paper investigates the differentially private problem of the average consensus for a class of discrete-time multi-agent network systems(MANSs). Based on the MANSs,a new distributed differentially private consensus algorithm(DPCA) is developed. To avoid continuous communication between neighboring agents, a kind of intermittent communication strategy depending on an event-triggered function is established in our DPCA. Based on our algorithm, we carry out the detailed analysis including its convergence, its accuracy, its privacy and the trade-off between the accuracy and the privacy level, respectively. It is found that our algorithm preserves the privacy of initial states of all agents in the whole process of consensus computation. The trade-off motivates us to find the best achievable accuracy of our algorithm under the free parameters and the fixed privacy level. Finally, numerical experiment results testify the validity of our theoretical analysis. | Aijuan Wang Xiaofeng Liao Haibo He | 2019 | IEEE/CAA Journal of Automatica Sinica2019，6，1： | 12 |
| 7 | Characterizing oxygenated volatile organic compounds and their sources in rural atmospheres in China显示文摘Oxygenated volatile organic compounds(OVOCs) are important precursors and products of atmospheric secondary pollution. The sources of OVOCs, however, are still quite uncertain,especially in the atmosphere with much pollution in China. To study the sources of OVOCs in rural atmospheres, a proton transfer reaction mass spectrometry(PTR-MS) was deployed at a northern rural site(WD) and a southern rural site(YMK) in China during the summer of 2014 and 2016, respectively. The continuous observation showed that the mean concentration of TVOCs(totally 17 VOCs) measured at WD(52.4 ppbv) was far higher than that at YMK(11.1 ppbv), and the OVOCs were the most abundant at both the two sites. The diurnal variations showed that local sources of OVOCs were still prominent at WD, while regional transport influenced YMK much. The photochemical age-based parameterization method was then used to quantitatively apportion the sources of ambient OVOCs. The anthropogenic primary sources at WD and YMK contributed less(2%–16%) to each OVOC species. At both the sites, the atmospheric background had a dominant contribution(~ 50%) to acetone and formic acid, while the anthropogenic secondary formation was the main source(~ 40%) of methanol and MEK. For acetaldehyde and acetic acid, the biogenic sources were their largest source(~ 40%) at WD, while the background(39%) and anthropogenic secondary formation(42%) were their largest sources at YMK, respectively. This study reveals the complexity of sources of OVOCs in China, which urgently needs explored further. | Yu Han Xiaofeng Huang Chuan Wang Bo Zhu Lingyan He | 2019 | Journal of Environmental Sciences2019，31，7： | 12 |
| 8 | Gas-to-particle conversion of atmospheric ammonia and sampling artifacts of ammonium in spring of Beijing显示文摘PM2.5 and gaseous pollutants(SO2,HNO2,HNO3,HCl,and NH3) were simultaneously collected by Partisol- Model 2300 Sequential Speciation Sampler with denuder-filter pack system in the spring of 2013 in Beijing.Water-soluble inorganic ions and gaseous pollutants were measured by Ion Chromatography.Results showed that the concentrations of NH3,NH+ 4and PM2.5 had similar diurnal variation trends and their concentrations were higher at night than in daytime.The results of gas-to-particle conversion revealed that [NH3]:[NH+4] ratio was usually higher than 1; however,it was less than 1 and the concentration of NH+4 increased significantly during the haze episode,indicating that NH3 played an important role in the formation of fine particle.Research on the sampling artifacts suggested that the volatilization loss of NH+4 was prevalent in the traditional single filter-based sampling.The excess loss of HNO3 and HCl resulted from ammonium-poor aerosols and semivolatile inorganic species had severe losses in the clean day,whereas the mass of NH+ 4was usually overestimated during the single filter-based sampling due to the positive artifacts.Correlation analysis was used to evaluate the influence of meteorological conditions on the volatilization loss of NH+4.It was found that the average relative humidity and temperature had great effects on the loss of NH+4.The loss of NH+4 was significantly under high temperature and low humidity,and tended to increase with the increasing of absorption of gaseous pollutants by denuder.The total mass of volatile loss of NH+4,NO- 3and Cl- could not be ignored and its maximum value was 12.17 μg m-3.Therefore it is important to compensate sampling artifacts for semivolatile inorganic species. | WEI LianFang DUAN JingChun TAN JiHua MA YongLiang HE KeBin WANG ShuXiao HUANG XiaoFeng ZHANG YuanXun | 2015 | Science China Earth Sciences2015，58，3： | 11 |
| 9 | An H3K27me3 demethylase-HSFA2 regulatory loop orchestrates transgenerational thermomemory in Arabidopsis显示文摘Global warming has profound effects on plant growth and fitness.Plants have evolved sophisticated epigenetic machinery to respond quickly to heat,and exhibit transgenerational memory of the heat-induced release of post-transtriptional gene silencing(PTGS).However,how thermomemory is transmitted to progeny and the physiological relevance are elusive.Here we show that heat-induced HEAT SHOCK TRANSCRIPTION FACTOR A2(HSFA2)directly activates the H3K27me3 demethylase RELATIVE OF EARLY FLOWERING 6(REF6),which in turn derepresses HSFA2.REF6 and HSFA2 establish a heritable feedback loop,and activate an E3 ubiquitin ligase,SUPPRESSOR OF GENE SILENCING 3(SGS3)-INTERACTING PROTEIN 1(SGIP1).SGIP1-mediated SGS3 degradation leads to inhibited biosynthesis of trans-acting siRNA(tasiRNA).The REF&HSFA2 loop and reduced tasiRNA converge to release HEAT-INDUCED TAS1 TARGET 5(HTT5),which drives early flowering but attenuates immunity.Thus,heat induces transmitted phe no types via a coordi nated epigenetic network involvi ng histone demethylases,tran scriptio n factors,and tasiRNAs,ensuring reproductive success and transgenerational stress adaptation. | Junzhong Liu Lili Feng Xueting Gu Xian Deng Qi Qiu Qun Li Yingying Zhang Muyang Wang Yiwen Deng Ertao Wang Yuke He Isabel Baurle Jianming Li Xiaofeng Cao Zuhua He | 2019 | Cell Research2019，29，5： | 10 |
| 10 | Transcriptional Regulation of miR528 by OsSPL9 Orchestrates Antiviral Response in Rice显示文摘Many microRNAs (miRNAs) are critical regulators of plant antiviral defense.However,little is known about how these miRNAs respond to virus invasion at the transcriptional level.We previously show that defense against Rice stripe virus (RSV) invasion entailed a reduction of miR528 accumulation in rice,alleviating miR528-mediated degradation of L-Ascorbate Oxidase (AO) mRNA and bolstering the antiviral activity of AO.Here we show that the miR528-A0 defense module is regulated by the transcription factor SPL9.SPL9 displayed high-affinity binding to specific motifs within the promoter region of miR528 and activated the expression of miR528 gene in vivo.Loss-of-function mutations in SPL9 caused a significant reduction in miR528 accumulation but a substantial increase of AO mRNA,resulting in enhanced plant resistance to RSV.Conversely,transgenic overexpression of SPL9 stimulated the expression of miR528 gene,hence lowering the level of AO mRNA and compromising rice defense against RSV.Importantly,gain in RSV susceptibility did not occur when SPL9 was overexpressed in mir528 loss-of-function mutants,or in transgenic rice expressing a miR528-resistant AO.Taken together,the finding of SPL9-mediated transcriptional activation of miR528 expression adds a new regulatory layer to the miR528-A0 antiviral defense pathway. | Shengze Yao Zhirui Yang Rongxin Yang Yu Huang Ge Guo Xiangyue Kong Ying Lan Tong Zhou He Wang Wenming Wang Xiaofeng Cao Jianguo Wu Yi Li | 2019 | Molecular Plant2019，12，8： | 10 |

| 12 | A LysM Receptor Heteromer Mediates Perception of Arbuscular Mycorrhizal Symbiotic Signal in Rice显示文摘Symbiotic microorganisms improve nutrient uptake by plants.To initiate mutualistic symbiosis with arbus-cular mycorrhizal(AM)fungi,plants perceive Myc factors,including lipochitooligosaccharides(LCOs)and short-chain chitooligosaccharides(CO4/CO5),secreted by AM fungi.However,the molecular mechanism of Myc factor perception remains elusive.In this study,we identified a heteromer of LysM receptor-like kinases consisting of OsMYR1/OsLYK2 and OsCERK1 that mediates the perception of AM fungi in rice.CO4 directly binds to OsMYR1,promoting the dimerization and phosphorylation of this receptor complex.Compared with control plants,Osmyr1 and Oscerk1 mutant rice plants are less sensitive to Myc factors and show decreased AM colonization.We engineered transgenic rice by expressing chimeric receptors that respectively replaced the ectodomains of OsMYR1 and OsCERK1 with those from the homologous Nod factor receptors MtNFP and MtL YK3 of Medicago truncatula.Transgenic plants displayed increased cal-cium oscillations in response to Nod factors compared with control rice.Our study provides significant mechanistic insights into AM symbiotic signal perception in rice.Expression of chimeric Nod/Myc recep-tors achieves a potentially important step toward generating cereals that host nitrogen-fixing bacteria. | Jiangman He Chi Zhang Huiling Dai Huan Liu Xiaowei Zhang Jun Yang Xi Chen Yayun Zhu Dapeng Wang Xiaofeng Qi Weichao Li Zhihui Wang Guoyong An Nan YU Zuhua He Yong-Fei Wang Youli Xiao Peng Zhang Ertao Wang | 2019 | Molecular Plant2019，12，12： | 9 |

| 15 | Source apportionment of PM_(2.5)light extinction in an urban atmosphere in China显示文摘Haze in China is primarily caused by high pollution of atmospheric fine particulates(PM2.5).However, the detailed source structures of PM2.5 light extinction have not been well established, especially for the roles of various organic aerosols, which makes haze management lack specified targets. This study obtained the mass concentrations of the chemical compositions and the light extinction coefficients of fine particles in the winter in Dongguan, Guangdong Province, using high time resolution aerosol observation instruments. We combined the positive matrix factor(PMF) analysis model of organic aerosols and the multiple linear regression method to establish a quantitative relationship model between the main chemical components, in particular the different sources of organic aerosols and the extinction coefficients of fine particles with a high goodness of fit(R^2= 0.953). The results show that the contribution rates of ammonium sulphate,ammonium nitrate, biomass burning organic aerosol(BBOA), secondary organic aerosol(SOA) and black carbon(BC) were 48.1%, 20.7%, 15.0%, 10.6%, and 5.6%, respectively. It can be seen that the contribution of the secondary aerosols is much higher than that of the primary aerosols(79.4% versus 20.6%) and are a major factor in the visibility decline. BBOA is found to have a high visibility destroying potential, with a high mass extinction coefficient, and was the largest contributor during some high pollution periods. A more detailed analysis indicates that the contribution of the enhanced absorption caused by BC mixing state was approximately 37.7% of the total particle absorption and should not be neglected. | Zijuan Lan Bin Zhang Xiaofeng Huang Qiao Zhu Jinfeng Yuan Liwu Zeng Min Hu Lingyan He | 2018 | Journal of Environmental Sciences2018，30，1： | 7 |

| 17 | Statistical and frequency analysis of the pressure fluctuation in a fluidized bed of non-spherical particles显示文摘In this paper,the pressure fluctuation in a fluidized bed was measured and processed via standard deviation and power spectrum analysis to investigate the dynamic behavior of the transition from the bubbling to turbulent regime.Two types[Geldart B and D) of non-spherical particles,screened from real bed materials,and their mixture were used as the bed materials.The experiments were conducted in a semiindustrial testing apparatus.The experimental results indicated that the fluidization characteristics of the non-spherical Geldart D particles differed from that of the spherical particles at gas velocities beyond the transition velocity U_c.The standard deviation of the pressure fluctuation measured in the bed increased with the gas velocity,while that measured in the plenum remained constant.Compared to the coarse particles,the fine particles exerted a stronger influence on the dynamic behavior of the fluidized bed and promoted the fluidization regime transition from bubbling toward turbulent.The power spectrum of the pressure fluctuation was calculated using the auto-regressive(AR) model;the hydrodynamics of the fluidized bed were characterized by the major frequency of the power spectrum of the pressure fluctuation.By combining the standard deviation analysis,a new method was proposed to determine the transition velocity U_k via the analysis of the change in the major frequency.The first major frequency was observed to vary within the range of 1.5 to 3 Hz. | Honghao He Xiaofeng Lu Wei Shuang Quanhai Wang Yinhu Kang Liyun Yan Xuanyu Ji Guangyu Luo Hai Liu | 2014 | Particuology2014，12，5： | 6 |

| 19 | Simplified ultra-tightly coupled BDS/INS integrated navigation system显示文摘Due to advantages such as low cost, small size, low weight, low power consumption, powerful capability of anti-jamming, and high dynamics, ultra-tightly coupled GNSS/MIMU integrated navigation systems are extensively used in projectile and precision-guided munitions. To overcome the nonlinearity of baseband signal processing and the complexity of the navigation filter, in this paper, we design a novel architecture for the ultra-tightly coupled(UTC) Beidou navigation satellite system(BDS)/INS integration based on the BDS B3 signal, including the combination of code phase and carrier phase dynamics baseband prefilter model, and the navigation filter navigation error propagation and measurement models. To eliminate the clock state components, i.e., the receiver clock offset and clock drift, the pseudorange, delta pseudorange, and delta pseudorange rate residuals obtained from baseband signal prefilters are differenced between two satellites. Based on the BDS/INS simulator, a test system for the UTC BDS/INS integrated navigation system is developed and UTC performance is evaluated. Some preliminary conclusions are formed about the effectiveness of the UTC BDS/INS integration approach. | Kanghua TANG Bing LUO Xiaofeng HE | 2016 | Science China(Information Sciences)2016，59，11： | 6 |
| 20 | LncRNA DPP10-AS1 promotes malignant processes through epigenetically activating its cognate gene DPP10 and predicts poor prognosis in lung cancer patients显示文摘Objective:The purpose of this study was to explore the function and gene expression regulation of the newly identified lnc RNA DPP10-AS1 in lung cancer,and its potential value as a prognostic biomarker.Methods:q RT-PCR and Western blot were conducted to detect the expression of DDP10-AS1 and DPP10 in lung cancer cell lines and tissues.The effects of DDP10-AS1 on DPP10 expression,cell growth,invasion,apoptosis,and in vivo tumor growth were investigated in lung cancer cells by Western blot,rescue experiments,colony formation,flow cytometry,and xenograft animal experiments.Results:The novel antisense lnc RNA DPP10-AS1 was found to be highly expressed in cancer tissues(P<0.0001),and its upregulation predicted poor prognosis in patients with lung cancer(P=0.0025).Notably,DPP10-AS1 promoted lung cancer cell growth,colony formation,and cell cycle progression,and repressed apoptosis in lung cancer cells by upregulating DPP10 expression.Additionally,DPP10-AS1 facilitated lung tumor growth via upregulation of DPP10 protein in a xenograft mouse model.Importantly,DPP10-AS1 positively regulated DPP10 gene expression,and both were coordinately upregulated in lung cancer tissues.Mechanically,DPP10-AS1 was found to associate with DPP10 m RNA but did not enhance DPP10 m RNA stability.Hypomethylation of DPP10-AS1 and DPP10 contributed to their coordinate upregulation in lung cancer.Conclusions:These findings indicated that the upregulation of the antisense lnc RNA DPP10-AS1 promotes lung cancer malignant processes and facilitates tumorigenesis by epigenetically regulating its cognate sense gene DPP10.DPP10-AS1 may serve as a candidate prognostic biomarker and a potential therapeutic target in lung cancer. | Haihua Tian Jinchang Pan Shuai Fang Chengwei Zhou Hui Tian Jinxian He Weiyu Shen Xiaodan Meng Xiaofeng Jin Zhaohui Gong | 2021 | Cancer Biology & Medicine2021，18，3： | 5 |
