1Transportation characteristics of δ^(13)C in the plants-soil-bedrock-cave system in Chongqing karst area显示文摘Here we use an analytical method to determine δ13C in local plants and organic matter in the soils above Furong cave,Chongqing,China.We also monitored δ13C in dissolved inorganic carbon(DIC) of drip water,δ13C of active deposits under the drip waters,and the concentration of air CO2(PCO2).Based on these,we preliminarily studied the transportation characteristics of stable carbon isotope(13C) in cave system of the subtropical karst area.The average δ13C value of 27 local plant samples,which belong to 16 families,was -32‰ and the weighted δ13C for surface dry biomass was -33‰.We found that for 54 soil samples collected from 5 soil profiles,δ13C of soil organic matters was -22‰,which could be attributed to the different transportation rates of stable carbon isotopes during the decomposition of plants and organic matters in soils.The relatively lighter 12C tended to transfer into gaseous CO2,which made the relatively heavier 13C concentrated in the soils.On the basis of monitoring of DIC-δ13C in drip waters from July 2009 to June 2010,we found that values in winter months were heavier and values in summer months were lighter in general,the reason of which was that in summer months,both the temperature and the humidity were comparatively higher,resulted in more CO2 with lighter δ13C generated from organic matters decomposition and plants respiration.The average DIC -δ13C value was -11‰,about 11‰ heavier than the δ13C of organic matters in soils,which proved that part of DIC in cave drip water was sourced from dissolution of inorganic carbonate(host rock,with heavier δ13C).As for the δ13C of active deposits at five drip water sites in Furong cave,they had almost the same variation with relatively light values.In other words,these active speleothems were deposited at equilibrium conditions for isotopic fractionation.These results suggest that the carbon isotopic information of speleothems could be used to track the evolution of local vegetation in certain situations.Li TingYong Li HongChun Xiang XiaoJing Kuo Tz-Shing Li JunYun Zhou FuLi Chen HongLi Peng LingLi 2012Science China Earth Sciences2012,55,4:18

3High-Resolution Mesoscale Analysis Data from the South China Heavy Rainfall Experiment (SCHeREX): Data Generation and Quality Evaluation显示文摘In this study, the observational data acquired in the South China Heavy Rainfall Experiment (SCHeREX) from May to July 2008 and 2009 were integrated and assimilated with the US National Oceanic and Atmospheric Administration's (NOAA) Local Analysis and Prediction System (LAPS; information available online at http://gffzzc2aa3fc9434744efhufk6ckqwk6bu6b6w.ffgz.tsg.suse.edu.cn). A high-resolution mesoscale analysis dataset was then generated at a spatial resolution of 5 km and a temporal resolution of 3 h in four observational areas: South China, Central China, Jianghuai area, and Yangtze River Delta area. The quality of this dataset was evaluated as follows. First, the dataset was qualitatively compared with radar reflectivity and TBB image for specific heavy rainfall events so as to examine its capability in reproduction of mesoscale systems. The results show that the SCHeREX analysis dataset has a strong capability in capturing severe mesoscale convective systems. Second, the mean deviation and root mean square error of the SCHeREX mesoscale analysis fields were analyzed and compared with radiosonde data. The results reveal that the errors of geopotential height, temperature, relative humidity, and wind of the SCHeREX analysis were within the acceptable range of observation errors. In particular, the average error was 45 m for geopotential height between 700 and 925 hPa, 1.0-1.1°C for temperature, less than 20% for relative humidity, 1.5-2.0 m s-1 for wind speed, and 20-25° for wind direction. The above results clearly indicate that the SCHeREX mesoscale analysis dataset is of high quality and sufficient reliability, and it is applicable to refined mesoscale weather studies.NI Yunqi CUI Chunguang LI Hongli PENG Juxiang QIU Xuexing ZHANG Yanxia XU Xiaolin GAO Mei JIE Lianshu ZHANG Wenhua 2011Acta meteorologica Sinica2011,25,4:2
4Vertical Profiles of Volatile Organic Compounds in Suburban Shanghai显示文摘As Volatile Organic Compounds(VOCs)are one of the precursors of ozone,their distribution and variable concentrations are highly related to local ozone pollution control.In this study,we obtained vertical profiles of VOCs in Shanghai’s Jinshan district on 8 September and 9 September in 2016 to investigate their distribution and impact on local atmospheric oxidation in the near surface layer.Vertical samples were collected from heights between 50 m and 400 m by summa canisters using an unmanned aerial vehicle(UAV).Concentrations of VOCs(VOCs refers to the 52 species measured in this study)varied minimally below 200 m,and decreased by 21.2%from 100 m to 400 m.The concentrations of VOCs above 200 m decreased significantly in comparison to those below 200 m.The proportions of alkanes and aromatics increased from 55.2%and 30.5%to 57.3%and 33.0%,respectively.Additionally,the proportion of alkenes decreased from 13.2%to 8.4%.Toluene and m/p-xylene were the key species in the formation of SOA and ozone.Principal component analysis(PCA)revealed that the VOCs measured in this study mainly originated from industrial emissions.Yuhan LIU Hongli WANG Shengao JING Ming ZHOU Shenrong LOU Kun QU Wanyi QIU Qian WANG Shule LI Yaqin GAO Yusi LIU Xiaobing LI Zhong-Ren PENG Junhui CHEN Keding LU 2021Advances in Atmospheric Sciences2021,38,7:1

8Effects of shrub-grass patterns on soil detachment and hydraulic parameters of slope in the Pisha sandstone area of Inner Mongolia,China显示文摘The characteristics of soil holding capacity for different shrub-grass patterns are important to research the mechanisms regulating vegetation on slopes.The objective of this study was to describe the characteristics and mecha-nisms of soil erosion and hydraulic parameters under differ-ent vegetation patterns in the Pisha sandstone area of Inner Mongolia on lands of 8°slope gradient.We carried out field scouring experiments on five different shrub-grass patterns as treatments,viz no shrubs(GL),shrubs on the upper part of the slope(SU),middle part of the slope(SM)and lower part of the slope(SL).We designated bare slope(BL)as the control.We employed three different water flow rates(15,20,30 L·min^(−1)).Our results showed that the contribution of plant root systems to slope sediment reduction ranged from 64 to 84%.The root systems proved to be the main contributing factor to reduction of erosion by vegetation.The relationship between soil detachment rate,stream flow power,and flow unit stream power under different scouring discharge rates showed that soil detachment declined in rank order as:BL>GL>SU>SM>SL.The SL pat-tern had the lowest soil detachment rate(0.098 g·m^(−2)·s^(−1)),flow stream power(2.371 W·m^(−2)),flow unit stream power(0.165 m·s^(−1))and flow shear stress(16.986 Pa),and proved to be the best erosion combating pattern.The results of decision coefficient and path analysis showed that stream power was the most important hydraulic parameter for describing soil detachment rate.The combination of stream power and shear stress,namely Dr=0.1ω−0.03τ−0.56(R^(2)=0.924),most accurately simulated the soil detachment characteristics on slopes.Our study suggests that the risk of soil ero-sion can be reduced by planting shrub-grass mixes on these slopes.Under the conditions of limited water resources and economy,the benefit of sediment reduction can be maxi-mized by planting shrubbery on the lower parts of slopes.Peng Chen Jianying Guo Tiegang Zhang Zhi Dong Hongli Li Suqian Qiu Xiaoxue Chen 2022Journal of Forestry Research2022,33,2:1
9Nuclear EPL-HAM complex is essential for the development of chloroplasts显示文摘Chloroplasts most likely originated from the endosymbiosis of cyanobacterial ancestors,entering the eukaryotic lineage about 1.0-1.5 billion years ago(Parfrey et al.,2011;Archibald,2015).Consequently,their biogenesis depends on genetic information from both the nuclear and chloroplast genomes.Photosynthetic housekeeping genes of core components in photosystemsⅠandⅡ(PSI and PSII)are encoded by the plastid genome。Bo Ding Hongli Xie Kangning Zhang He Li Yushi Gao Jing Zhang Bin Xu Lianwei Peng Guofeng Yang Guo-Liang Wang Upinder Gill Zeng-Yu Wang Maofeng Chai 2022Journal of Genetics and Genomics2022,49,12:1
10Traffic Labeller: Collecting Internet Traffic Samples with Accurate Application Information显示文摘Traffic classification research has been suffering from a trouble of collecting accurate samples with ground truth.A model named Traffic Labeller(TL) is proposed to solve this problem.TL system captures all user socket calls and their corresponding application process information in the user mode on a Windows host.Once a sending data call has been captured,its 5-tuple {source IP,destination IP,source port,destination port and transport layer protocol},associated with its application information,is sent to an intermediate NDIS driver in the kernel mode.Then the intermediate driver writes application type information on TOS field of the IP packets which match the 5-tuple.In this way,each IP packet sent from the Windows host carries their application information.Therefore,traffic samples collected on the network have been labelled with the accurate application information and can be used for training effective traffic classification models.PENG Lizhi ZHANG Hongli YANG Bo CHEN Yuehui WU Tong 2014China Communications2014,11,1:1
11Flow-rate Characteristics Measurement of Regulators Based on the Pressure Response in an Isothermal Tank显示文摘Regulators are important components in pneumatic system,and their flow-rate characteristics are the key parameters for designers.According to the correlatively international standard and national standard of China,which describe the flow-rate characteristics measurement method of pneumatic regulators,the pressure and the flow are measured point by point,and then the flow-rate characteristics curve is plotted point to point.This method has some disadvantages,such as equipment complexity,much air consumption,and low efficiency.To settle the problems presented above,this paper puts forward a new high efficient and energy saving flow-rate characteristics measurement method of regulators,which is based on the pressure response when charging and discharging to an isothermal tank without any flow meters.The measurement principle,the system and the steps are introduced.And the tracking differentiator is used for the data processing of the pressure difference.Two typical kinds of regulators were experimentally investigated,and their flow-rate characteristics curves were obtained with the new and the conventional method,respectively.Comparatively,it's proved that this new method is feasible because it is not only able to meet the demand of the measurement precision,but also to save energy and improve efficiency.Compared to the conventional method,the new method takes only about 1/10 amount of time and consumes about only 1/30 amount of air.Hopefully it will be able to serve as an international standard of flow-rate characteristics measurement method of regulators.FAN Wei ZHANG Hongli WANG Tao PENG Guangzheng ONEYAMA Naotake 2009Chinese Journal of Mechanical Engineering2009,22,5:1
12血清胱抑素C、内生肌酐清除率及尿微量白蛋白在恶性肿瘤含顺铂化疗患者肾功能评价中的地位(英文)显示文摘Objective:Chemotherapy drugs such as platinum may cause damage to the renal function,creatinine clearance(Ccr),as a 'golden standard' indicator in clinical evaluation of renal function,was limited in application due to complicated detection steps.By detecting the expression of serum Cystatin C(Cys C),Ccr and urinary micro-albumin(UMA),this study was designed to analyze and discuss their roles and status in renal function evaluation for cancer patients before and after chemotherapy with platinum.Methods:We retrospectively reviewed 110 patients who receiving platinum-containing protocols or non-platinum-containing ones,and got the expression of Cys C,Ccr(was calculated by Cockcroft-Gault equation) and UMA,then analyzed whether there were differences for Cys C,Ccr and UMA in those patients;for patients with mildly impaired renal function(Ccr between 50-75 mL/min),whether there were differences for Cys C and UMA before and after chemotherapy with platinum.Results:There was statistical significance for Ccr,Cys C and UMA in patients who receiving platinum-containing protocols(85.01 ± 28.40) vs(76.79 ± 26.63) mL/min,(1.49 ± 0.50) vs(1.80 ± 0.84) mg/L and(14.30 ± 9.15) vs(16.90 ± 10.95) mg/L,P = 0.00,0.00 and 0.01),and no statistical significance for those receiving non-platinum-containing ones(89.45 ± 29.69) vs(86.78 ± 27.96) mL/min,(1.51 ± 0.78) vs(1.63 ± 0.73)mg/L and(17.31 ± 10.46) vs(16.59 ± 8.33) mg/L,P = 0.45,0.07 and 0.57);and there were also significant differences for Cys C for patients with mildly impaired renal function before and after chemotherapy(1.68 ± 0.55) vs(2.04 ± 0.68) mg/L,P = 0.03),while no statistical significance for UMA for the same ones(21.11 ± 10.06) vs(21.22 ± 8.81) mg/L,P = 0.93).There were statistical significance both for Cys C and UMA before and after chemotherapy in platinum-containing group,but the AUC for Ccr and Cys C is greater than that for UMA(P < 0.02).Conclusion:Cys C and UMA can both access renal dysfunction early after chemotherapy,but Cys C is more sensitive than UMA in reflecting early renal dysfunction,so Cys C can replace Ccr and become a reliable indicator in the assessment of renal function for cancer patients before and after chemotherapy especially with platinum.Xun Cai Peng Xue Meizhen Gu Jiong Hu Hongli Gu Haiyan Yang Liwei Wang 2011The Chinese-German Journal of Clinical Oncology2011,10,4:1
13Indoor Propagation of Transgenic Glyphosate-tolerant Rapeseed (Brassica napus L.) and Transfer Breeding for Herbicide Tolerance显示文摘[Objectives] This study was conducted to investigate the possibility of screening for herbicide resistance in the early stage of rapes growth. [Methods] Eight treatments were set for a herbicide concentration experiment. [Results] Rape sprouts were highly sensitive to the herbicide glyphosate, and even a very low concentration of glyphosate solution(187 mg/L) was sufficient to kill most of the rape seedlings, while the genetically modified herbicide-tolerant rape could tolerate higher concentrations of the herbicide. Low concentrations of glyphosate could be used for screening at the sprout stage, and the results of herbicide-tolerance screening were consistent with PCR testing. [Conclusions] This study lays a technical and material foundation for accelerating the cultivation of new herbicide-resistant rape varieties suitable for rapeseed production areas in the lower reaches of the Yangtze River.Xiaoying ZHOU Yaoyao WU Qi PENG Sanxiong FU Wei ZHANG Hongli ZHU Jiefu ZHANG Song CHEN 2021Agricultural Biotechnology2021,10,1:0
14A COMBINED FULL-WAVE BCG-FFT METHOD FOR RADIATION OF MICROSTRIP ANTENNA ARRAYS显示文摘A method of combining BiConjugate Gradient(BCG) with Fast Fourier Transform(FFT) to analyze the radiation of microstrip antenna arrays is presented, where the spatially discrete BCG-FFT for analyzing microstrip structure is used and the del operators on Green's functions are transferred from the singular kernel to the expansion and testing functions.

15月经周期中免疫球蛋白G N-糖基化的周期性变化显示文摘Immunoglobulin G(IgG)is the most abundant plasma glycoprotein and a prominent humoral immune mediator.Glycan composition affects the affinity of IgG to ligands and consequent immune responses.The modification of IgG N-glycosylation is considered to be one of the various mechanisms by which sex hormones modulate the immune system.Although the menstrual cycle is the central sex hormonerelated physiological process in most women of reproductive age,IgG N-glycosylation dynamics during the menstrual cycle have not yet been investigated.To fill this gap,we profiled the plasma IgG Nglycans of 70 healthy premenopausal women at 12 time points during their menstrual cycles(every 7 days for 3 months)using hydrophilic interaction ultra-performance liquid chromatography(HILIC-UPLC).We observed cyclic periodic changes in the N-glycosylation of IgG in association with the menstrual cycle phase and sex hormone concentration in plasma.On the integrated cohort level,the modeled average menstrual cycle effect on the abundance of IgG N-glycosylation traits was low for each trait,with the highest being 1.1%for agalactosylated N-glycans.However,intrapersonal changes were relatively high in some cases;for example,the largest difference between the minimum and maximum values during the menstrual cycle was up to 21%for sialylated N-glycans.Across all measurements,the menstrual cycle phase could explain up to 0.72%of the variation in the abundance of a single IgG glycosylation trait of monogalactosylation.In contrast,up to 99%of the variation in the abundance of digalactosylation could be attributed to interpersonal differences in IgG N-glycosylation.In conclusion,the average extent of changes in the IgG N-glycopattern that occur during the menstrual cycle is small;thus,the IgG N-glycoprofiling of women in large sample-size studies can be performed regardless of menstrual cycle phase.Julija Juric Hongli Peng Manshu Song Frano Vuckovic JelenaŠimunovic Irena TrbojevicAkmacic Youxin Wang Jiaonan Liu Qing Gao Hao Wang Qiaoyun Chu Marija Pezer Wei Wang Gordan Lauc 2023Engineering2023,,7:0

17Heterogeneous reaction of NO_(2) with feldspar, three clay minerals and Arizona Test Dust显示文摘Heterogeneous reaction of NO_(2) with mineral dust aerosol may play important roles in troposphere chemistry,and has been investigated by a number of laboratory studies.However,the influence of mineralogy on this reaction has not been well understood,and its impact on aerosol hygroscopicity is not yet clear.This work investigated heterogeneous reactions of NO_(2)(∼10 ppmv)with K-feldspar,illite,kaolinite,montmorillonite and Arizona Test Dust(ATD)at room temperature as a function of relative humidity(<1%to 80%)and reaction time(up to 24 hr).Heterogeneous reactivity towards NO_(2) was low for illite,kaolinite,montmorillonite and ATD,and uptake coefficients of NO_(2),γ(NO_(2)),were determined to be around or smaller than 1×10^(−8);K-feldspar exhibited higher reactivity towards NO_(2),and CaCO_(3) is most reactive among the nine mineral dust samples considered in this and previous work.After heterogeneous reaction with NO_(2) for 24 hr,increase in hygroscopicity was nearly insignificant for illite,kaolinite and montmorillonite,and small but significant for K-feldspar;in addition,large increase in hygroscopicity was observed for ATD,although the increase in hygroscopicity was still smaller than CaCO_(3).Mingjin Tang Xiaohong Jia Lanxiadi Chen Wenjun Gu Chengpeng Huang FuWang Lan Luo Hongli Wang Xinming Wang Chao Peng 2023Journal of Environmental Sciences2023,,8:0
18Breather molecules and localized interaction solutions in the(2+1)-dimensional BLMP equation显示文摘The(2+1)-dimensional Boiti-Leon-Manna-Pempinelli(BLMP)equation is an important integrable model.In this paper,we obtain the breather molecule,the breather-soliton molecule and some localized interaction solutions to the BLMP equation.In particular,by employing a compound method consisting of the velocity resonance,partial module resonance and degeneration of the breather techniques,we derive some interesting hybrid solutions mixed by a breather-soliton molecule/breather molecule and a lump,as well as a bell-shaped soliton and lump.Due to the lack of the long wave limit,it is the first time using the compound degeneration method to construct the hybrid solutions involving a lump.The dynamical behaviors and mathematical features of the solutions are analyzed theoretically and graphically.The method introduced can be effectively used to study the wave solutions of other nonlinear partial differential equations.Jiaxin Qi Hongli An Peng Jin 2021Communications in Theoretical Physics2021,73,12:0
19SVD based scale transform invariant observable degree for LTI system显示文摘Dear editor,The basic concept of observability is used to express the possibility to recover the state from measurements in modern control theory[1–3].It is a qualitative parameter,which cannot reflect the observable degree(OD)ability[4,5].Therefore,the OD is presented to quantitatively obtain the function.The quantitative parameter is effective for indicating the exact degree of estimation ability.Quanbo GE Peng ZHUO Hongli HE Zhentao HU Zhansheng DUAN Junzhi YU 2021Science China(Information Sciences)2021,64,3:0
20Observation-based sources evolution of non-methane hydrocarbons (NMHCs) in a megacity of China显示文摘Both concentrations and emissions of many air pollutants have been decreasing due to implement of control measures in China,in contrast to the fact that an increase in emissions of non-methane hydrocarbons(NMHCs)has been reported.This study employed seven years continuous NMHCsmeasurements and the related activities data of Shanghai,a megacity in China,to explore evolution of emissions and effectiveness of air pollution control measures.The mixing ratio of NMHCs showed no statistical interannual changes,of which their compositions exhibited marked changes.This resulted in a decreasing trend of ozone formation potential by 3.8%/year(p<0.05,the same below),which should be beneficial to ozone pollution mitigation as its production in Shanghai is in the NMHCs-limited regime.Observed alkanes,aromatics and acetylene changed by+3.7%/year,-5.9%/year and-7.4%/year,respectively,and alkenes showed no apparent trend.NMHCs sources were apportioned by a positive matrix factorization model.Accordingly,vehicular emissions(-5.9%/year)and petrochemical industry emissions(-7.1%/year)decreased significantly,but the decrease slowed down;significant reduction in solvent usage(-9.0%/year)appeared after 2010;however,emissions of natural gas(+12.6%/year)and fuel evaporation(with an increasing fraction)became more important.The inconsistency between observations and inventories was found in interannual trend and speciation as well as source contributions,emphasizing the need for further validation in NMHCs emission inventory.Our study confirms the effectiveness of measures targeting mobile and centralized emissions from industrial sources and reveals a need focusing on fugitive emissions,which provided new insights into future air policies in polluted region.Yarong Peng Hongli Wang Qian Wang Shengao Jing Jingyu An Yaqin Gao Cheng Huang Rusha Yan Haixia Dai Tiantao Cheng Qiang Zhang Meng Li Jianlin Hu Zhihao Shi Li Li Shengrong Lou Shikang Tao Qinyao Hu Jun Lu Changhong Chen 2023Journal of Environmental Sciences2023,,2:0
