| 1 | Characteristics of atmospheric single particles during haze periods in a typical urban area of Beijing:A case study in October,2014显示文摘To investigate the composition and possible sources of particles, especially during heavy haze pollution, a single particle aerosol mass spectrometer(SPAMS) was deployed to measure the changes of single particle species and sizes during October of 2014, in Beijing. A total of 2,871,431 particles with both positive and negative spectra were collected and characterized in combination with the adaptive resonance theory neural network algorithm(ART-2a). Eight types of particles were classified: dust particles(dust, 8.1%), elemental carbon(EC, 29.0%), organic carbon(OC, 18.0%), EC and OC combined particles(ECOC, 9.5%),Na-K containing particles(Na K, 7.9%), K-containing particles(K, 21.8%), organic nitrogen and potassium containing particles(KCN, 2.3%), and metal-containing particles(metal,3.6%). Three haze pollution events(P1, P2, P3) and one clean period(clean) were analyzed,based on the mass and number concentration of PM_(2.5)and the back trajectory results from the hybrid single particle Lagrangian integrated trajectory model(Hysplit-4 model). Results showed that EC, OC and K were the major components of single particles during the three haze pollution periods, which showed clearly increased ratios compared with those in the clean period. Results from the mixing state of secondary species of different types of particles showed that sulfate and nitrate were more readily mixed with carbon-containing particles during haze pollution episodes than in clean periods. | Lang Liu Yanli Wang Shiyong Du Wenjie Zhang Lujian Hou Sverre Vedal Bin Han Wen Yang Mindong Chen Zhipeng Bai | 2016 | Journal of Environmental Sciences2016，28，2： | 19 |
| 2 | Characteristics of Dried Soil Layers Under Apple Orchards of Different Ages and Their Applications in Soil Water Managements on the Loess Plateau of China显示文摘Negative soil water balance(i.e., water input < water output) can lead to soil desiccation and subsequently the occurrence of a dried soil layer(DSL). The DSLs are generally studied at a specific sampling depth(e.g., 500 cm), and the actual extent of DSLs remains unknown due to the challenge of collecting deep soil samples. To investigate the characteristics of actual DSLs under different ages of apple orchards and ascertain the optimal age of apple orchards for avoiding/controlling the formation of DSLs, soil samples were collected to a depth of 1 800 cm under apple orchards of different ages in Changwu on the Loess Plateau of China. As the ages increased, soil water content(SWC) and mean SWC in DSLs showed an overall decreasing trend, whereas while DSL thickness and the quantity of water deficit(QWD) in DSLs demonstrated an increasing trend. The DSL was the thickest(1 600 cm) under the 17-year-old orchard, the forming velocity of DSL thickness was the highest at the apple tree growth stage of 9–17 years(168 cm year-1), and the highest increasing velocity of QWD(-181 mm year-1) was also observed at this stage. The thickness of DSL was significantly correlated with growth age and root depth of apple trees(r > 0.88), whereas the QWD and mean SWC in DSLs were found to have no correlation with them. The optimal age of apple orchards for avoiding/controlling the formation of DSLs was about 9 years. This information provided pertinent references for the management of deep water resources by controlling the growth age of plants. | WANG Yunqiang SHAO Mingan LIU Zhipeng ZHANG Chencheng | 2015 | Pedosphere2015，25，4： | 18 |

| 4 | Modeling the global ionospheric total electron content with empirical orthogonal function analysis显示文摘In the present work we model the global ionospheric total electron content (TEC) with the analysis of empirical orthogonal functions (EOF). The obtained statistical eigen modes, which makeup the modeled TEC, consist of two factors: the eigen vectors mapping TEC patterns at latitude and longitude (or local time LT), and the corresponding coefficients displaying the TEC variations in different time scales, i.e., the solar cycle, the yearly (annual and semiannual) and the diurnal universal time variations. It is found that the EOF analysis can separate the TEC variations into chief processes and the first two modes illustrate the most of the ionospheric climate properties. The first mode contains both the semiannual component which shows the semiannual ionospheric anomaly and the annual component which shows the annual or non-seasonal ionospheric anomaly. The second mode contains mainly the annual component and shows the normal seasonal ionospheric variation at most latitudes and local time sectors. The annual component in the second mode also manifests seasonal anomaly of the ionosphere at higher mid-latitudes around noontime. It is concluded that the EOF analysis, as a statistical eigen mode method, is resultful in analyzing the ionospheric climatology hence can be used to construct the empirical model for the ionospheric climatology. | WAN WeiXing DING Feng REN ZhiPeng ZHANG ManLian LIU LiBo NING BaiQi | 2012 | Science China(Technological Sciences)2012，55，5： | 15 |

| 7 | Structure and kinematic analysis of the deepwater area of the Qiongdongnan Basin through a seismic interpretation and analogue modeling experiments显示文摘Located at the northwest continental slope of the South China Sea, the Qiongdongnan Basin bears valley-shaped bathymetry deepening toward east. It is separated from the Yinggehai Basin through NW-trending Indo-ChinaRed River shear zone, and connected with NW subsea basin through the Xisha Trough. Along with the rapid progress of the deepwater exploration, large amounts of high resolution geophysical and geological data were accumulated. Scientific researches about deepwater basins kept revealing brand new tectonic and sedimentary discoveries. In order to summarize the structural features and main controlling factors of the deepwater Qiongdongnan Basin, a series of researches on basin architecture, fault activities, tectonic deformation and evolution were carried out. In reference to analogue modeling experiments, a tectonic situation and a basin formation mechanism were discussed. The researches indicate that: the northern boundary of the Qiongdongnan Basin is strongly controlled by No. 2 fault. The overlapping control of two stress fields from the east and the west made the central depression zone extremely thinned. Combined with the changed stress field, the segmentation of a preexisting weakness zone made the sags in the east experiencing different rifting histories from the west ones. The NE-trending west segment of the Qiongdongnan Basin experienced strong rifting during Eocene, while the roughly EW-trending sags in the east segment show strong rifting during late Eocene and early Oligocene.Local structures such as NW-trending basal fault and inherited uplifts controlled the lateral segmentation. So first order factors such as regional stress field and preexisting weakness zone controlled the basin zonation, while the second order factors determined the segmentation from east to west. | SUN Zhen WANG Zhenfeng SUN Zhipeng WANG Zhangwen ZHANG Wei HE Lijuan | 2015 | Acta Oceanologica Sinica2015，34，4： | 10 |

| 9 | Features of colorectal cancer in China stratified by anatomic sites:A hospital-based study conducted in university-affiliated hospitals from 2014 to 2018显示文摘Objective:The clinical and biological characteristics of colorectal cancer have been found to differ depending on the anatomic site of the cancer.However,for Chinese patients,there is limited information on the proportion of cases at each site and the related features.In this study,we explored the location,distribution and other features of colorectal cancers at each anatomic site in Chinese patients.Methods:We conducted a hospital-based study using hospitalization summary reports from 10 Peking University-affiliated hospitals from 2014 to 2018;the reports covered a total of 2,097,347 hospitalizations.Incident cases were chosen as the study population,and their epidemiological features were further analyzed.Results:A total of 20,739 colorectal cancer patients were identified.Rectum was the most common location(48.3%)of the cancer,whereas the proportions of patients with distal and proximal colon cancer were 24.5%and18.6%,respectively.Patients with rectal cancer were predominantly male and were the youngest for all anatomical sites(each P<0.001).The highest proportion of emergency admissions,the longest hospital stays and the highest hospitalization costs were found in patients with proximal colon cancer(each P<0.001).The proximal colon cancer subgroup included the highest proportions of patients with medical histories of cholecystectomy,cholecystolithiasis and/or gallbladder polyps and appendectomy(P=0.009,P<0.001 and P<0.001,respectively).The distal colon cancer subgroup included the highest proportions of patients with medical histories of diabetes and hypertension(P<0.001,respectively).Conclusions:The patterns of colorectal cancer observed in this study differ from those reported for Western patients and show a significantly higher proportion of patients with rectal cancer.Different epidemiological features were also found based on anatomic sites.Further studies based on tumor location should be conducted to facilitate more accurate screening and treatment. | Ruize Qu Yanpeng Ma Liyuan Tao Xiaoyuan Bao Xin Zhou Bingyan Wang Fei Li Siyi Lu Lin Tuo Siyan Zhan Zhipeng Zhang Wei Fu | 2021 | Chinese Journal of Cancer Research2021，33，4： | 10 |
| 10 | Local icariin application enhanced periodontal tissue regeneration and relieved local inflammation in a minipig model of periodontitis显示文摘Periodontitis is an inflammatory autoimmune disease. Treatment should alleviate inflammation, regulate the immune reaction and promote periodontal tissue regeneration. Icariin is the main active ingredient of Epimedii Folium, and it is a promising compound for the enhancement of mesenchymal stem cell function, promotion of bone formation, inhibition of bone resorption, alleviation of inflammation and regulation of immunity. The study investigated the effect of icariin on periodontal tissue regeneration in a minipig model of periodontitis. The minipig model of periodontitis was established. Icariin was injected locally. The periodontal clinical assessment index, a computed tomography(CT) scan, histopathology and enzyme-linked immune sorbent assay(ELISA)were used to evaluate the effects of icariin. Quantitative analysis results 12 weeks post-injection demonstrated that probing depth,gingival recession, attachment loss and alveolar bone regeneration values were(3.72 ± 1.18) mm vs.(6.56 ± 1.47) mm,(1.67 ± 0.59)mm vs.(2.38 ± 0.61) mm,(5.56 ± 1.29) mm vs.(8.61 ± 1.72) mm, and(25.65 ± 5.13) mm3 vs.(9.48 ± 1.78) mm3 in the icariin group and0.9% NaCl group, respectively. The clinical assessment, CT scan, and histopathology results demonstrated significant enhancement of periodontal tissue regeneration in the icariin group compared to the 0.9% NaCl group. The ELISA results suggested that the concentration of interleukin-1 beta(IL-1β) in the icariin group was downregulated compared to the 0.9% NaCl group, which indicates that local injection of icariin relieved local inflammation in a minipig model of periodontitis. Local injection of icariin promoted periodontal tissue regeneration and exerted anti-inflammatory and immunomodulatory function. These results support the application of icariin for the clinical treatment of periodontitis. | Xiuli Zhang Nannan Han Guoqing Li Haoqing Yang Yangyang Cao Zhipeng Fan Fengqiu Zhang | 2018 | International Journal of Oral Science2018，10，3： | 9 |
| 11 | Geology and hydrocarbon accumulations in the deepwater of the northwestern South China Sea——with focus on natural gas显示文摘The deepwater of the northwestern South China Sea is located in the central to southern parts of the Qiongdongnan Basin(QDN Basin),which is a key site for hydrocarbon exploration in recent years.In this study,the authors did a comprehensive analysis of gravity-magnetic data,extensive 3D seismic survey,cores and cuttings,paleontology and geochemical indexes,proposed the mechanism of natural gas origin,identified different oil and gas systems,and established the model of hydrocarbon accumulations in the deep-water region.Our basin tectonic simulation indicates that the evolution of QDN Basin was controlled by multiple-phased tectonic movements,such as Indochina-Eurasian Plate collision,Tibetan Uplift,Red River faulting and the expansion of the South China Sea which is characterized by Paleogene rifting,Neogene depression,and Eocene intensive faulting and lacustrine deposits.The drilling results show that this region is dominated by marineterrestrial transitional and neritic-bathyal facies from the early Oligocene.The Yacheng Formation of the early Oligocene is rich in organic matter and a main gas-source rock.According to the geological-geochemical data from the latest drilling wells,Lingshui,Baodao,Changchang Sags have good hydrocarbon-generating potentials,where two plays from the Paleogene and Neogene reservoirs were developed.Those reservoirs occur in central canyon structural-lithologic trap zone,Changchang marginal trap zone and southern fault terrace of Baodao Sag.Among them,the central canyon trap zone has a great potential for exploration because the various reservoirforming elements are well developed,i.e.,good coal-measure source rocks,sufficient reservoirs from the Neogene turbidity sandstone and submarine fan,faults connecting source rock and reservoirs,effective vertical migration,late stage aggregation and favorable structural–lithological composite trapping.These study results provide an important scientific basis for hydrocarbon exploration in this region,evidenced by the recent discovery of the significant commercial LS-A gas field in the central canyon of the Lingshui Sag. | WANG Zhenfeng SUN Zhipeng ZHANG Daojun ZHU Jitian LI Xushen HUANG Baojia GUO Minggang JIANG Rufeng | 2015 | Acta Oceanologica Sinica2015，34，10： | 9 |
| 12 | Emission factors, ozone and secondary organic aerosol formation potential of volatile organic compounds emitted from industrial biomass boilers显示文摘To evaluate the potential benefits of biomass use for air pollution control, this paper identified and quantified the emissions of major reactive organic compounds anticipated from biomass-fired industrial boilers. Wood pellets(WP) and straw pellets(SP) were burned to determine the volatile organic compound emission profiles for each biomass-boiler combination. More than 100 types of volatile organic compounds(VOCs) were measured from the two biomass boilers. The measured VOC species included alkanes, alkenes and acetylenes, aromatics, halocarbons and carbonyls. A single coal-fired boiler(CB) was also studied to provide a basis for comparison. Biomass boiler 1(BB1) emitted relatively high proportions of alkanes(28.9%–38.1% by mass) and alkenes and acetylenes(23.4%–40.8%),while biomass boiler 2(BB2) emitted relatively high proportions of aromatics(27.9%–29.2%)and oxygenated VOCs(33.0%–44.8%). The total VOC(TVOC) emission factors from BB1(128.59–146.16 mg/kg) were higher than those from BB2(41.26–85.29 mg/kg). The total ozone formation potential(OFP) ranged from 6.26 to 81.75 mg/m^3 with an average of 33.66 mg/m^3 for the two biomass boilers. The total secondary organic aerosol potential(SOAP) ranged from 61.56 to 211.67 mg/m^3 with an average of 142.27 mg/m^3 for the two biomass boilers.The emission factors(EFs) of TVOCs from biomass boilers in this study were similar to those for industrial coal-fired boilers with the same thermal power. These data can supplement existing VOC emission factors for biomass combustion and thus enrich the VOC emission inventory. | Chunmei Geng Wen Yang Xuesong Sun Xinhu Wang Zhipeng Bai Xia Zhang | 2019 | Journal of Environmental Sciences2019，31，9： | 8 |
| 13 | Stream-computing of High Accuracy On-board Real-time Cloud Detection for High Resolution Optical Satellite Imagery显示文摘This paper focuses on the time efficiency for machine vision and intelligent photogrammetry, especially high accuracy on-board real-time cloud detection method. With the development of technology, the data acquisition ability is growing continuously and the volume of raw data is increasing explosively. Meanwhile, because of the higher requirement of data accuracy, the computation load is also becoming heavier. This situation makes time efficiency extremely important. Moreover, the cloud cover rate of optical satellite imagery is up to approximately 50%, which is seriously restricting the applications of on-board intelligent photogrammetry services. To meet the on-board cloud detection requirements and offer valid input data to subsequent processing, this paper presents a stream-computing of high accuracy on-board real-time cloud detection solution which follows the “bottom-up” understanding strategy of machine vision and uses multiple embedded GPU with significant potential to be applied on-board. Without external memory, the data parallel pipeline system based on multiple processing modules of this solution could afford the “stream-in, processing, stream-out” real-time stream computing. In experiments, images of GF-2 satellite are used to validate the accuracy and performance of this approach, and the experimental results show that this solution could not only bring up cloud detection accuracy, but also match the on-board real-time processing requirements. | Mi WANG Zhiqi ZHANG Zhipeng DONG Shuying JIN Hongbo SU | 2019 | Journal of Geodesy and Geoinformation Science2019，2，2： | 7 |
| 14 | High-resolution, in vivo multimodal photoacoustic microscopy, optical coherence tomography, and fluorescence microscopy imaging of rabbit retinal neovascularization显示文摘Photoacoustic microscopy(PAM)is an emerging imaging technology that can non-invasively visualize ocular structures in animal eyes.This report describes an integrated multimodality imaging system that combines PAM,optical coherence tomography(OCT),and fluorescence microscopy(FM)to evaluate angiogenesis in larger animal eyes.High-resolution in vivo imaging was performed in live rabbit eyes with vascular endothelial growth factor(VEGF)-induced retinal neovascularization(RNV).The results demonstrate that our multimodality imaging system can noninvasively visualize RNV in both albino and pigmented rabbits to determine retinal pathology using PAM and OCT and verify the leakage of neovascularization using FM and fluorescein dye.This work presents high-resolution visualization of angiogenesis in rabbits using a multimodality PAM,OCT,and FM system and may represent a major step toward the clinical translation of the technology. | Wei Zhang Yanxiu Li Van Phuc Nguyen Ziyi Huang Zhipeng Liu Xueding Wang Yannis M.Paulus | 2018 | Light(Science & Applications)2018，7，1： | 7 |
| 15 | Crystalline boron nitride nanosheets by sonication-assisted hydrothermal exfoliation显示文摘A simple method to prepare two-dimensional hexagonal boron nitride(h-BN) scalably is essential for practical applications. Despite intense research in this area, high-yield production of two-dimensional h-BN with large size and high crystallinity is still a key challenge. In the present work, we propose a simple exfoliation process for boron nitride nanosheets(BNNSs) with high crystallinity by sonication-assisted hydrothermal method, via the synergistic effect of the high pressure, and cavitation of the sonication. Compared with the method only by sonication, the sonication-assisted hydrothermal method can get the fewer-layer BNNSs with high crystallinity.Meanwhile, it can reach higher yield of nearly 1.68%, as the hydrothermal method with the yield of only 0.12%. The simple sonication-assisted hydrothermal method has potential applications in exfoliating other layered materials, thus opening new ways to produce other layered materials in high yield and high crystallinity. | Zhaobo TIAN Kexin CHEN Siyuan SUN Jie ZHANG Wei CUI Zhipeng XIE Guanghua LIU | 2019 | Journal of Advanced Ceramics2019，8，1： | 7 |

| 18 | Response of Pinus taiwanensis growth to climate changes at its southern limit of Daiyun Mountain, China's Mainland Fujian Province显示文摘The Pinus taiwanensis trees of a Chinese endemic species form pure forests at infertile sites in humid subtropical China, which can aid soil reservation and ecological resiliency at such sites. Herein, we used dendrochronological methods to investigate the growth patterns and their relationship with climate by analyzing 158 cores of 79 P. taiwanensis trees at 4 sites in their southernmost distribution in China's Mainland at Daiyun Mountain in Fujian Province. Tree growths at sites with favorable conditions generally showed an age-related growth trend, which decreased from approximately 5 mm to 0.5 mm in about a century. Trees in moderately stressed environments established high growth in their juvenile periods but were highly susceptible to environmental stresses such as a sharp growth decline in the 1990 s. The temperature in February and the moisture in July are the major limiting factors for most of the tree growths, except for a few extremely stressed P. taiwanensis trees. The growth of the dwarf P. taiwanensis trees, with all ring diameters of the first 20 years less than 4 mm, is mainly limited by the dry climate in May. Under the potential future warming trend, drought stress can be particularly threatening to these dwarf P. taiwanensis trees, which are likely to be the germplasm resources for this species in this region. | CHEN Dan FANG KeYan LI YingJun DONG ZhiPeng ZHANG Yu ZHOU FeiFei | 2016 | Science China Earth Sciences2016，59，2： | 6 |
| 19 | Hydrogen production by reforming methane in a corona inducing dielectric barrier discharge and catalyst hybrid reactor显示文摘A novel corona inducing dielectric barrier discharge(CIDBD) and catalyst hybrid reactor was developed for reforming methane. This corona inducing technique allows dielectric barrier discharge(DBD) to occur uniformly in a large gap at relatively low applied voltage.Hydrogen production by reforming methane with steam and air was investigated with the hybrid reactor under atmospheric pressure and temperatures below 600°C.The effects of input power,O2/C molar ratio and preheat temperature on methane conversion and hydrogen selectivity were investigated experimentally.It was found that higher methane conversions were obtained at higher discharge power,and methane conversion increased significantly with input power less than 50 W;the optimized molar ratio of O2/C was 0.6 to obtain the highest hydrogen selectivity(112%);under the synergy of dielectric barrier discharge and catalyst,methane conversion was close to the thermodynamic equilibrium conversion rate. | ZHOU ZhiPeng ZHANG JiMin YE TaoHong ZHAO PingHui XIA WeiDong | 2011 | Chinese Science Bulletin2011，56，20： | 6 |
| 20 | Quantifying public health benefits of environmental strategy of PM2.5 air quality management in Beijing–Tianjin–Hebei region,China显示文摘In 2013,China issued 'Air Pollution Prevention and Control Action Plan(Action Plan)' to improve air quality.To assess the benefits of this program in Beijing-Tianjin-Hebei(BTH)region,where the density of population and emissions vary greatly,we simulated the air quality benefit based on Ben MAP to satisfy the Action Plan.In this study,we estimate PM_(2.5) concentration using Voronoi spatial interpolation method on a grid with a spatial resolution of 1 × 1 km^2.Combined with the exposure-response function between PM_(2.5) concentration and health endpoints,health effects of PM_(2.5) exposure are analyzed.The economic loss is assessed by using the willingness to pay(WTP) method and human capital(HC) method.When the PM_(2.5) concentration falls by 25% in BTH and reached 60 μg/m^3 in Beijing,the avoiding deaths will be in the range of 3175 to 14051 based on different functions each year.Of the estimated mortality attributable to all causes,3117 annual deaths were due to lung cancer,1924 – 6318 annual deaths were due to cardiovascular,and343 – 1697 annual deaths were due to respiratory.Based on WTP,the estimated monetary values for the avoided cases of all cause mortality,cardiovascular mortality,respiratory mortality and lung cancer ranged from 1110 to 29632,673 to 13325,120 to 3579,1091 to 6574 million yuan,respectively.Based on HC,the corresponding values for the avoided cases of these four mortalities were 267 to 1178,161 to 529,29 to 143 and 261 million yuan,respectively. | Li Chen Mengshuang Shi Suhuan Li Shuang Gao Hui Zhang Yanling Sun Jian Mao Zhipeng Bai Zhongliang Wang Jiang Zhou | 2017 | Journal of Environmental Sciences2017，29，7： | 6 |
