| 1 | Significant downward trend of SO_2 observed from 2005 to 2010 at a background station in the Yangtze Delta region,China显示文摘SO2 is an important gas in atmosphere with great environmental and climate implications.SO2 emission in China has been receiving great attention as the economy grows and the amount of coal consumption has increased in the past few decades.SO2 has been observed from July 2005 to June 2010 at Linan WMO GAW regional station(30.3 °N,119.73 °E,138 m a.s.l.) located in the Yangtze Delta region in eastern China.These observation data are analyzed to understand the trend of regional SO2 background concentration.Strict quality controls are conducted to ensure the temporal comparability of the data.Significant downward trend with ?2.4 ppb/yr(P < 0.0001) of surface SO2 is observed from 2005 to 2010,especially after 2008.The average concentration of SO2 from July 2005 to June 2008 is 14.2±3.1 ppb,which is slightly higher than the mean values of 13.5±5.1 ppb during 1999?2000 and is two folds of the average value(7.1±3.1 ppb) from July 2008 to June 2010.More than 50% of the SO2 has been cut down after 2008 in the Yangtze Delta region due to the implementation of stricter emission control measures.The peak SO2 concentration appears around 10 o'clock in the morning after 2009 while appears at night before 2009.These diurnal variations of SO2 might indicate that after 2009,more SO2 is from the vertical exchange process than from the local accumulation. | QI HuangXiong LIN WeiLi XU XiaoBin YU XiangMing MA QianLi | 2012 | Science China Chemistry2012，55，7： | 7 |
| 2 | Surgical Therapeutic Strategy for Non-small Cell Lung Cancer with Mediastinal Lymph Node Metastasis (N2)显示文摘Background and objective Approximately 30% of patients who are diagnosed with non-small cell lung cancer (NSCLC) are classified as N2 on the basis of metastasis to the mediastinal lymph nodes. The effectiveness of surgery for these patients remains controversial. Although surgeries in recent years are proved to be effective to some extent,yet due to many reasons,5-year survival rate after surgery varies greatly from patient to patient. Thus it is necessary to select patients who have a high probability of being be cured through an operation,who are suitable to receive surgery and the best surgical methods so as to figure out the conditions under which surgical treatment can be chosen and the factors that may influence prognosis. Methods 165 out of 173 patients with N2 NSCLC were treated with surgery in our department from January 1999 to May 2003,among whom 130 were male,43 female and the sex ratio was 3:1,average age 53,ranging from 29 to 79. The database covers the patients’ complete medical history including the information of their age,sex,location and size of tumor,date of operation,surgical methods,histologic diagnosis,clinical stage,post-operative TNM stage,neoadjuvant treatment and chemoradiotherapy. The methods of clinical stage verification include chest X-ray,chest CT,PET,mediastinoscopy,bronchoscope (+?),brain CT or MRI,abdominal B ultrasound (or CT),and bone ECT. The pathological classification was based on the international standard for lung cancer (UICC 1997). Survival time was analyzed from the operation date to May 2008 with the aid of SPSS (Statistical Package for the Social Sciences) program. Kaplan-Meier survival analysis,Log-rank test and Cox multiplicity were adopted respectively to obtain patients’ survival curve,survival rate and the impact possible factors may have on their survival rate. Results The median survival time was 22 months,with 3-year survival rate reaching 28.1% and 5-year survival rate reaching 19.0%. Age,sex,different histological classification and postoperative chemoradiotherapy seem to have no correlation with 5-year survival rate. In all N2 subtypes,5-year survival rate is remarkably higher for unexpected N2 discovered at thoractomy and proven N2 stage before preoperative work-up and receive a mediastinal down-staging after induction therapy (P<0.01),reaching 30.4% and 27.3% respectively. 5-year survival rate for single station lymph node metastasis were 27.8%,much higher compared with 9.3% for multiple stations (P<0.001). Induction therapy which downstages proven N2 in 73.3% patients gains them the opportunity of surgery. The 5-year survival rate were 23.6% and 13.0% for patients who had complete resection and those who had incomplete resection (P<0.001). Patients who underwent lobectomy (23.2%) have higher survival rate,less incidence rate of complication and mortality rate,compared with pneumonectomy (14.8%) (P<0.01). T4 patients has a 5-year survival rate as low as 11.1%,much less than T1 (31.5%) and T2 (24.3%) patients (P=0.01). It is noted through Cox analysis that completeness of resection,number of positive lymph node stations and primary T status have significant correlativity with 5-year survival rate. Conclusion It is suggested that surgery (lobectomy preferentially) is the best solution for T1 and T2 with primary tumor have not invaded pleura or the distance to carina of trachea no less than 2 cm,unexpected N2 discovered at thoractomy when a complete resection can be applied,and proven N2 discovered during preoperative work-up and is down-staged after induction therapy. Surgical treatment is the best option,lobectomy should be prioritized in operational methods since ite rate of complication and morality are lower than that of pneumonectomy. Patients’ survival time will not benefit from surgery if they are with lymph nodes metastasis of multiple stations (Bulky N2 included) and T4 which can be partially removed. Neoadjuvant chemotherapy increases long-term survival rate of those with N2 proven prior to surgery. However,postoperative radiotherapy decreases local recurrence rate but does not contribute to patients’ long-term survival rate. | Qianli MA Deruo LIU Yongqing GUO Bin SHI Zhiyi SONG Yanchu TIAN | 2010 | 中国肺癌杂志2010，13，4： | 7 |
| 3 | Morphology,composition,and sources of individual aerosol particles at a regional background site of the YRD,China显示文摘Aerosol samples were collected at Lin'an, a background site of Yangtze River Delta(YRD).Morphology, size, composition, and mixing state of individual aerosol particles were characterized by transmission electron microscopy(TEM) coupled with energy dispersive X-ray spectroscopy(EDS), and the soluble ions of PM_(1.0) were studied by aerosol mass spectrometer(AMS). The daily average AMS mass concentrations of sulfate, nitrate, and ammonium were about 5.8, 8.6, and 5.6 μg/m^3, respectively. Individual aerosol particles were classified into seven types: S-rich, K-rich, organic matter(OM), soot, fly ash, metal, and mineral. S-rich particles were dominant in all size bins, and 51%(by number) of S-rich particles were internally mixed with other particles. The fraction of organic coating particles was 13.7% in morning, 25.2% in afternoon, and 11% in evening, suggesting that the strong photochemical process during afternoon produced more secondary organic aerosols(SOA) on the surface of inorganic particles. Fly ash and metal particles were abundant during the day, suggesting the influence of emissions from coal-fired power plants and steel plants. The results indicate that the intense industrial emissions in the YRD significantly transported to the background areas. PM_(2.5) concentration may be lower in background air than in urban air but complex mixing state of aerosol particles indicates that the long-range transported particles substantially influenced the background air quality. | Liang Xu A.P.Lingaswamy Yinxiao Zhang Lei Liu Yuanyuan Wang Jian Zhang Qianli Ma Weijun Li | 2019 | Journal of Environmental Sciences2019，31，3： | 6 |
| 4 | A survey on ensemble learning显示文摘Despite significant successes achieved in knowledge discovery,traditional machine learning methods may fail to obtain satisfactory performances when dealing with complex data,such as imbalanced,high-dimensional,noisy data,etc.The reason behind is that it is difficult for these methods to capture multiple characteristics and underlying structure of data.In this context,it becomes an important topic in the data mining field that how to effectively construct an efficient knowledge discovery and mining model.Ensemble learning,as one research hot spot,aims to integrate data fusion,data modeling,and data mining into a unified framework.Specifically,ensemble learning firstly extracts a set of features with a variety of transformations.Based on these learned features,multiple learning algorithms are utilized to produce weak predictive results.Finally,ensemble learning fuses the informative knowledge from the above results obtained to achieve knowledge discovery and better predictive performance via voting schemes in an adaptive way.In this paper,we review the research progress of the mainstream approaches of ensemble learning and classify them based on different characteristics.In addition,we present challenges and possible research directions for each mainstream approach of ensemble learning,and we also give an extra introduction for the combination of ensemble learning with other machine learning hot spots such as deep learning,reinforcement learning,etc. | Xibin DONG Zhiwen YU Wenming CAO Yifan SHI Qianli MA | 2020 | Frontiers of Computer Science2020，14，2： | 4 |
| 5 | Photoinduced large polaron transport and dynamics in organic-inorganic hybrid lead halide perovskite with terahertz probes显示文摘Organic-inorganic hybrid metal halide perovskites(MHPs)have attracted tremendous attention for optoelectronic applications.The long photocarrier lifetime and moderate carrier mobility have been proposed as results of the large polaron formation in MHPs.However,it is challenging to measure the effective mass and carrier scattering parameters of the photogenerated large polarons in the ultrafast carrier recombination dynamics.Here,we show,in a one-step spectroscopic method,that the optical-pump and terahertz-electromagnetic probe(OPTP)technique allows us to access the nature of interplay of photoexcited unbound charge carriers and optical phonons in polycrystalline CH_(3)NH_(3)PbI_(3)(MAPbI_(3))of about 10μm grain size.Firstly,we demonstrate a direct spectral evidence of the large polarons in polycrystalline MAPbI_(3).Using the Drude-Smith-Lorentz model along with the Frӧhlich-type electron-phonon(e-ph)coupling,we determine the effective mass and scattering parameters of photogenerated polaronic carriers.We discover that the resulting moderate polaronic carrier mobility is mainly influenced by the enhanced carrier scattering,rather than the polaron mass enhancement.While,the formation of large polarons in MAPbI_(3)polycrystalline grains results in a long charge carrier lifetime at room temperature.Our results provide crucial information about the photo-physics of MAPbI3 and are indispensable for optoelectronic device development with better performance. | Zuanming Jin Yan Peng Yuqing Fang Zhijiang Ye Zhiyuan Fan Zhilin Liu Xichang Bao Heng Gao Wei Ren Jing Wu Guohong Ma Qianli Chen Chao Zhang Alexey VBalakin Alexander PShkurinov Yiming Zhu Songlin Zhuang | 2022 | Light(Science & Applications)2022，11，8： | 4 |
| 6 | Evolution and protein interactions of AP2 proteins in Brassicaceae: Evidence linking development and environmental responses显示文摘Plants have evolved a large number of transcription factors(TF), which are enriched among duplicate genes,highlighting their roles in complex regulatory networks. The APETALA2/EREBP-like genes constitute a large plant TF family and participate in development and stress responses. To probe the conservation and divergence of AP2/EREBP genes,we analyzed the duplication patterns of this family in Brassicaceae and identified interacting proteins of representative Arabidopsis AP2/EREBP proteins. We found that many AP2/EREBP duplicates generated early in Brassicaceae history were quickly lost, but many others were retained in all tested Brassicaceae species, suggesting early functional divergence followed by persistent conservation. In addition,the sequences of the AP2 domain and exon numbers were highly conserved in rosids. Furthermore, we used 16 A.thaliana AP2/EREBP proteins as baits in yeast screens and identified 1,970 potential AP2/EREBP-interacting proteins,with a small subset of interactions verified in planta. Many AP2 genes also exhibit reduced expression in an antherdefective mutant, providing a possible link to developmental regulation. The putative AP2-interacting proteins participate in many functions in development and stress responses,including photomorphogenesis, flower development, pathogenesis, drought and cold responses, abscisic acid and auxin signaling. Our results present the AP2/EREBP evolution patterns in Brassicaceae, and support a proposed interaction network of AP2/EREBP proteins and their putative interacting proteins for further study. | Liping Zeng Yue Yin Chenjiang You Qianli Pan Duo Xu Taijie Jin Bailong Zhang Hong Ma | 2016 | Journal of Integrative Plant Biology2016，58，6： | 3 |
| 7 | Detection and Initial Response to a Type 2 Vaccine-Derived Poliovirus—Sichuan Province,China,2019显示文摘What is already known about this topic?After the type 2 strain of the live,attenuated poliovirus vaccine was withdrawn globally in 2016,any identification of a type 2 poliovirus is a Public Health Emergency of International Concern.A vaccinederived type 2 poliovirus(VDPV2)was identified in Sichuan,prompting an urgent,comprehensive investigation and response.What is added by this report?Type 2 monovalent,live,attenuated oral poliovirus vaccine(mOPV2)is being used to respond to the numerous VDPV2 outbreaks seen around the world.In contrast,the response in Sichuan used Sabin strain inactivated poliovirus(sIPV)to stop circulation of the VDPV2.In the 6 months following the vaccination response,there have been no VDPV2s detected in Sichuan,despite extensive search.What are the implications for public health practices?Further search for the VDPV2 must continue in order to determine whether transmission has been stopped.The ongoing investigation and response to the Sichuan VDPV2 is providing evidence to the Global Polio Eradication Initiative on managing VDPV2 outbreaks. | Jiushun Zhou Ning Wen Yong Zhang Qi Qi Chunxiang Fan Dongmei Yan Xiaoping Zhu Lixin Hao Shuangli Zhu Yu Liu Xiaozhen Ma Chao Ma Lei Nan Yong Chen Qianli Ma Cheng Wang Kun Deng Lei Cao Ge Shao Xianxiang Ding Hong Yang Zhijie An Lance ERodewald Aiqiang Xu Huaqing Wang Zijian Feng Zundong Yin Xianping Wu Wenbo Xu | 2020 | China CDC weekly2020，2，11： | 3 |
| 8 | A new measure to characterize multifractality of sleep electroencephalogram显示文摘Traditional methods for nonlinear dy-namic analysis,such as correlation dimension,Lyapunov exponent,approximate entropy,detrended fluctuation analysis,using a single parameter,cannot fully describe the extremely sophisticated behavior of electroencephalogram (EEG). The multifractal for-malism reveals more “hidden” information of EEG by using singularity spectrum to characterize its nonlin-ear dynamics. In this paper,the zero-crossing time intervals of sleep EEG were studied using multifractal analysis. A new multifractal measure Δasα was pro-posed to describe the asymmetry of singularity spec-trum,and compared with the singularity strength range Δα that was normally used as a degree indi-cator of multifractality. One-way analysis of variance and multiple comparison tests showed that the new measure we proposed gave better discrimination of sleep stages,especially in the discrimination be-tween sleep and awake,and between sleep stages 3 and 4. | MA Qianli NING Xinbao WANG Jun BIAN Chunhua | 2006 | Chinese Science Bulletin2006，51，24： | 3 |
| 9 | Acidic oxygen evolution reaction:Mechanism,catalyst classification,and enhancement strategies显示文摘As the most desirable hydrogen production device,the highly efficient acidic proton exchange membrane water electrolyzers(PEMWE)are severely limited by the sluggish kinetics of oxygen evolution reaction(OER)at the anode.Rutile IrO2 is a commercial acid-stable OER catalyst with poor activity and high cost,which has motivated the development of alternatives.However,hitherto most of the designed acidic OER catalysts have disadvantages of low activity or stability,which cannot meet the requirement of industrial applications.Thus,exploring suitable strategies to enhance the activity and stability of cost-effective acidic OER catalysts is crucial for developing the PEMWE technique.In this review,the main OER mechanisms,different types of catalysts,and their activity and stability characteristics are summarized and discussed,and then possible strategies to improve activity and stability are proposed.Finally,the problems and prospects of such catalysts are generalized to shed some light on the future research of advanced catalysts for acidic OER. | Qianli Ma Shichun Mu | 2023 | Interdisciplinary Materials2023，2，1： | 2 |
| 10 | Estimate of Hydrofluorocarbon Emissions for 2012–16 in the Yangtze River Delta, China显示文摘Hydrofluorocarbons(HFCs)have been widely used in China as substitutes for ozone-depleting substances,the production and use of which are being phased out under the Montreal Protocol.China is a major consumer of HFCs around the world,with its HFC emissions in CO2-equivalent contributing to about 18%of the global emissions for the period2012-16.Three methods are widely used to estimate the emissions of HFCs-namely,the bottom-up method,top-down method and tracer ratio method.In this study,the tracer ratio method was adopted to estimate HFC emissions in the Yangtze River Delta(YRD),using CO as a tracer.The YRD region might make a significant contribution to Chinese totals owing to its rapid economic growth.Weekly flask measurements for ten HFCs(HFC-23,HFC-32,HFC-125,HFC-134 a,HFC-143 a,HFC-152 a,HFC-227 ea,HFC-236 fa,HFC-245 fa and HFC-365 mfc)were conducted at Lin’an Regional Background Station in the YRD over the period 2012-16,and the HFC emissions were 2.4±1.4 Gg yr-1 for HFC-23,2.8±1.2 Gg yr-1 for HFC-32,2.2±1.2 Gg yr-1 for HFC-125,4.8±4.8 Gg yr-1 for HFC-134 a,0.9±0.6 Gg yr-1 for HFC-152 a,0.3±0.3 Gg yr-1 for HFC-227 ea and 0.3±0.2 Gg yr-1 for HFC-245 fa.The YRD total HFC emissions reached 53 Gg CO2-e yr-1,contributing 34%of the national total.The per capita HFC CO2-equivalent emissions rate was 240 kg yr-1,while the values of per unit area emissions and per million GDP emissions reached 150 Mg km-2yr-1 and 3500 kg yr-1(million CNY GDP)-1,which were much higher than national or global levels. | Jingjiao PU Honghui XU Bo YAO Yan YU Yujun JIANG Qianli MA Liqu CHEN | 2020 | Advances in Atmospheric Sciences2020，37，6： | 2 |
| 11 | Sign series entropy analysis of short-term heart rate variability显示文摘Complexity and nonlinearity approaches can be used to study the temporal and structural order in heart rate variability (HRV) signal, which is helpful for understanding the underlying rule and physiological essence of cardiovascular regulation. For clinical applications, methods suitable for short-term HRV analysis are more valuable. In this paper, sign series entropy analysis (SSEA) is proposed to characterize the feature of direction variation of HRV. The results show that SSEA method can detect sensitively physiological and pathological changes from short-term HRV signals, and the method also shows its robustness to nonstationarity and noise. Thus, it is suggested as an efficient way for the analysis of clinical HRV and other complex physiological signals. | BIAN ChunHua MA QianLi SI JunFeng WU XuHui SHAO Jun NING XinBao WANG DongJin | 2009 | Chinese Science Bulletin2009，54，24： | 2 |

| 17 | Diketopyrrolopyrrole-derived organic small molecular dyes for tumor phototheranostics显示文摘Cancer is one of the leading causes of human death around the world. Phototherapy, including photodynamic therapy(PDT) and photothermal therapy(PTT), is an emerging light-triggered cancer treatment and shows the advantages of non-invasiveness and low side effects. The design and preparation of efficient phototherapeutic agents are of great significance for phototherapy. Diketopyrrolopyrrole(DPP) is a small molecular organic dye featuring outstanding photophysical properties, facile tuning of structures and properties, and excellent photostability;thus, phototherapeutic agents based on organic small molecular DPP derivatives have attracted significant research attention for not only phototherapy but also photodiagnosis of fluorescence imaging(FLI) and photoacoustic imaging(PAI). This review summarizes the recent progress of various DPP-based organic small molecules on phototheranostics during the last five years. The molecular structure design and their phototheranostics performances are discussed in detail,as will be of great help for further creation of DPP-based phototheranostics. | Qianli Ma Xu Sun Weili Wang Dongliang Yang Cangjie Yang Qian Shen Jinjun Shao | 2022 | Chinese Chemical Letters2022，33，4： | 1 |
