1Accuracy improvement of GPS/MEMS-INS integrated navigation system during GPS signal outage for land vehicle navigation显示文摘To improve the reliability and accuracy of the global positioning system (GPS)/micro electromechanical system (MEMS)inertial navigation system (INS) integrated navigation system,this paper proposes two different methods.Based on wavelet threshold denoising and functional coefficient autoregressive (FAR) modeling,a combined data processing method is presented for MEMS inertial sensor,and GPS attitude information is also introduced to improve the estimation accuracy of MEMS inertial sensor errors.Then the positioning accuracy during GPS signal short outage is enhanced.To improve the positioning accuracy when a GPS signal is blocked for long time and solve the problem of the traditional adaptive neuro-fuzzy inference system (ANFIS) method with poor dynamic adaptation and large calculation amount,a self-constructive ANFIS (SCANFIS) combined with the extended Kalman filter (EKF) is proposed for MEMS-INS errors modeling and predicting.Experimental road test results validate the efficiency of the proposed methods.Honglei Qin Li Cong Xingli Sun 2012Journal of Systems Engineering and Electronics2012,23,2:13
2Comparison of nonhuman primates identified the suitable model for COVID-19显示文摘Identification of a suitable nonhuman primate(NHP)model of COVID-19 remains challenging.Here,we characterized severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection in three NHP species:Old World monkeys Macaca mulatta(M.mulatta)and Macaca fascicularis(M.fascicularis)and New World monkey Callithrix jacchus(C.jacchus).Infected M.mulatta and M.fascicularis showed abnormal chest radiographs,an increased body temperature and a decreased body weight.Viral genomes were detected in swab and blood samples from all animals.Viral load was detected in the pulmonary tissues of M.mulatta and M.fascicularis but not C.jacchus.Furthermore,among the three animal species,M.mulatta showed the strongest response to SARS-CoV-2,including increased inflammatory cytokine expression and pathological changes in the pulmonary tissues.Collectively,these data revealed the different susceptibilities of Old World and New World monkeys to SARS-CoV-2 and identified M.mulatta as the most suitable for modeling COVID-19.Shuaiyao Lu Yuan Zhao Wenhai Yu Yun Yang Jiahong Gao Junbin Wang Dexuan Kuang Mengli Yang Jing Yang Chunxia Ma Jingwen Xu Xingli Qian Haiyan Li Siwen Zhao Jingmei Li Haixuan Wang Haiting Long Jingxian Zhou Fangyu Luo Kaiyun Ding Daoju Wu Yong Zhang Yinliang Dong Yuqin Liu Yinqiu Zheng Xiaochen Lin Li Jiao Huanying Zheng Qing Dai Qiangming Sun Yunzhang Hu Changwen Ke Hongqi Liu Xiaozhong Peng 2020Signal Transduction and Targeted Therapy2020,5,1:5
3Seasonal and spatial variation in species diversity, abundance, and element accumulation capacities of macroalgae in mangrove forests of Zhanjiang, China显示文摘The objective of this study was to investigate whether there was distinctive seasonal and zonal variation in the species diversity, biomass, and element accumulation capacities of macroalgae in two major intertidal mangrove stand types(Avicennia marina assemblage and Sonneratia apetala assemblage) in the Zhanjiang region of southern China. Over a year, 31 species in 15 genera were identified in both mangrove assemblages, of which the dominant species were Cladophoropsis zollingeri and Enteromorpha clathrat. Macroalgal species were significantly most abundant in spring(p<0.05), followed by summer, winter, and autumn. Variation in the zonal distribution of macroalgal species was conspicuous in both intertidal mangrove assemblages, with the greatest abundance in the middle zone, and the least in the front zone. Patterns in the seasonal and zonal variation in macroalgal biomass in the S. apetala assemblage were similar to those of macroalgal species diversity in both mangrove assemblages. The seasonal patterns in tissue concentrations of 15 analyzed elements were not uniform among the macroalgae C. zollingeri, E. clathrata, and Gracilaria salicornia in the A. marina assemblage. All three species exhibited variation in their responses to ambient concentrations of different elements, implying their differential ability to absorb and selectively accumulate certain elements.ZHANG Yubin LI Yuan SHI Fei SUN Xingli LIN Guanghui 2014Acta Oceanologica Sinica2014,33,8:3
4An integrated strategy towards the facile synthesis of core-shell SiC-derived carbon@N-doped carbon for high-performance supercapacitors显示文摘Porous active core-shell carbon material with excellent synergistic effect has been regarded as a prospective material for supercapacitors.Herein,we report an integrated method for the facile synthesis of carbide-derived carbon(CDC)encapsulated with porous N-doped carbon(CDC@NC)towards highperformance supercapacitors.Polydopamine(PDA)as nitrogen and carbon sources was simply coated on SiC nanospheres to form SiC@PDA,which was then directly transformed into CDC@NC via a onestep molten salt electro-etching/in-situ doping process.The synthesized CDC@NC with hierarchically porous structure has a high specific surface area of 1191 m^(2) g^(-1).The CDC core and NC shell are typical amorphous carbon and more ordered N-doped carbon,respectively.Benefitting from its unique dual porous structures,the CDC@NC demonstrates high specific capacitances of 255 and 193 F g^(-1) at 0.5 and20 A g^(-1),respectively.The reaction mechanism of the electro-etching/in-situ doping process has also been investigated through experimental characterizations and theoretical density functional theory calculations.It is suggested that the molten salt electro-etching/in-situ doping strategy is promising for the synthesis of active core-shell porous carbon materials with synergistic properties for supercapacitors without the need for additional doping/activation processes.Zhongya Pang Guangshi Li Xingli Zou Chenteng Sun Conghui Hu Wei Tang Li Ji Hsien-Yi Hsu Qian Xu Xionggang Lu 2021Journal of Energy Chemistry2021,30,5:2

10Agricultural Investment Project Decisions Based on an Interactive Preference Disaggregation Model Considering Inconsistency显示文摘Agricultural investment project selection is a complex multi-criteria decision-making problem,as agricultural projects are easily influenced by various risk factors,and the evaluation information provided by decisionmakers usually involves uncertainty and inconsistency.Existing literature primarily employed direct preference elicitation methods to address such issues,necessitating a great cognitive effort on the part of decision-makers during evaluation,specifically,determining the weights of criteria.In this study,we propose an indirect preference elicitation method,known as a preference disaggregation method,to learn decision-maker preference models fromdecision examples.To enhance evaluation ease,decision-makers merely need to compare pairs of alternatives with which they are familiar,also known as reference alternatives.Probabilistic linguistic preference relations are employed to account for the presence of incomplete and uncertain information in such pairwise comparisons.To address the inconsistency among a group of decision-makers,we develop a pair of 0-1mixed integer programming models that consider both the semantics of linguistic terms and the belief degrees of decision-makers.Finally,we conduct a case study and comparative analysis.Results reveal the effectiveness of the proposed model in solving agricultural investment project selection problems with uncertain and inconsistent decision information.Xingli Wu Huchang Liao Shuxian Sun Zhengjun Wan 2024Computer Modeling in Engineering & Sciences2024,139,6:0
11Influences of vacancy defects on thermal conductivities of Ge thin films显示文摘The effects of vacancy defects on the thermal conductivity of Ge thin films were investigated by employing molecular dynamics(MD) simulations and theoretical analysis based on the Boltzmann equation.Both the MD and theoretical results show that the lattice thermal conductivity dramatically decreases with the increasing of vacancy concentration at 400 and 500 K.In addition,the dependence of vacancy concentration on the thermal conductivity of Ge thin films becomes less sensitive as the temperature increases.Theoretical results also confirm that the major part of the lattice thermal conductivity reduction is associated with the point-defect scattering and phonon-phonon scattering processes.ZHANG Xingli SUN Zhaowei 2011Rare Metals2011,30,4:0
12pH Numerical Simulation of the Desulfuration Acidic Effluent Discharge of Power Plant and Its Impact Prediction on Phytoplankton in Seawater显示文摘To understand the change regions of pH and the effect on phytoplankton while the acidic effluent of desulfuration from power plants draining into seawater,the changing modes of phytoplankton species and quantity to pH were established in seawater through laboratory survey in this work. Then,the ECOMSED model was applied to predict the change scope of pH and the ecological influences on phytoplankton due to the acidic effluent from a programming power plant in Zhanjiang Bay. The experimental results in laboratory showed that the species of phytoplankton changed with pH in a rule of convex parabola,and the quantity of phytoplankton decreased linearly with the fall of pH. The results of pH numerical simulation indicated that the acidic effluent from the power plant flowed zonally with tide. When the pH value of surface seawater decreased from the background value of 8. 0 to 7. 8,the extreme area influenced harmfully by the acidic effluent was near 30. 70 km2,accounting for about16.2% of the total area of Zhanjiang Bay( 190 km2). The predict results of ecological impact showed that if the species and quantity of phytoplankton decreased by5% in surface seawater,the corresponding extreme areas influenced harmfully by the acidic effluent were 0. 40 and 10. 81 km2,accounting respectively for 0. 21% and 0. 53% of the total area of Zhanjiang Bay. Moreover,around the outlet of the power plant where the pH value of seawater was near to 6. 8,the species and quantity of phytoplankton decreased most. However,the corresponding influenced area was rather small,just about0. 15 km2,accounting for 0.08% of the total area of Zhanjiang Bay.Zhang Jibiao Liang Chunlin Chen Chunliang Zhang Yubin Sun Xingli 2014Meteorological and Environmental Research2014,5,6:0
13Residues and sources of HCHs and DDTs in the sediments of land-based sewage outlet to the Zhanjiang Bay, China显示文摘Due to the large usage of DDT-containing antifouling paints and lindane in China, heavy residuals of DDTs and HCHs have been found in many fishing harbors, but there is lack of studies on this issue for the Zhanjiang Bay which is an important fishing harbor and mariculture zone in South China. To evaluate the pollution status and sources of HCHs and DDTs in the Zhanjiang Bay, the concentrations, spatial distributions and sources in the sediments of 11 land-based sewage outlets to the Zhanjiang Bay were investigated. Since the 1980 s, HCHs residuals had obviously decreased in studied areas, but DDTs had little change, even abnormally high levels were found in some sites. The content percentages and diagnostic ratios of HCHs isomers and DDTs showed that the source of HCHs was derived from soils around the bay and recent input of lindane, and DDTs were from historical residues of technical DDTs and fresh input of DDT-containing antifouling paints on fishing ships. Based on sediment quality guidelines, DDTs would be of more concern for the ecotoxicological risk on marine environment and adverse effects on benthonic organisms. This study indicated that lindane and DDT-containing products may be still used in some places of Zhanjiang City. It should be urgent to control their usage and clean the DDTs-contaminated sites by the local government.Lirong Zhao Yuzhen Shi Hui Zhao Jibiao Zhang Xingli Sun 2019Acta Oceanologica Sinica2019,38,12:0
14Wafer-Scale Synthesis of WS_(2) Films with In Situ Controllable p-Type Doping by Atomic Layer Deposition显示文摘Wafer-scale synthesis of p-type TMD films is critical for its commercialization in next-generation electro/optoelectronics.In this work,wafer-scale intrinsic n-type WS_(2)films and in situ Nb-doped p-type WS_(2)films were synthesized through atomic layer deposition(ALD)on 8-inchα-Al_(2)O_(3)/Si wafers,2-inch sapphire,and 1 cm^(2)GaN substrate pieces.The Nb doping concentration was precisely controlled by altering cycle number of Nb precursor and activated by postannealing.WS_(2)n-FETs and Nb-doped p-FETs with different Nb concentrations have been fabricated using CMOS-compatible processes.X-ray photoelectron spectroscopy,Raman spectroscopy,and Hall measurements confirmed the effective substitutional doping with Nb.The on/off ratio and electron mobility of WS_(2)n-FET are as high as 105 and 6.85 cm^(2)V^(-1)s^(-1),respectively.In WS_(2)p-FET with 15-cycle Nb doping,the on/off ratio and hole mobility are 10 and 0.016 cm^(2)V^(-1)s^(-1),respectively.The p-n structure based on n-and p-type WS_(2)films was proved with a 10^(4) rectifying ratio.The realization of controllable in situ Nb-doped WS_(2)films paved a way for fabricating wafer-scale complementary WS_(2)FETs.Hanjie Yang Yang Wang Xingli Zou Rongxu Bai Zecheng Wu Sheng Han Tao Chen Shen Hu Hao Zhu Lin Chen David W.Zhang Jack C.Lee Xionggang Lu Peng Zhou Qingqing Sun Edward T.Yu Deji Akinwande Li Ji 2022Research2022,,1:0
15Seasonal and spatial variations of macrobenthic community in intertidal Sargassum field off Naozhou Island, South China Sea显示文摘Seasonal and spatial variations in the macrobenthic community in an intertidal gulfweed field off Naozhou Island were investigated from April 2011 to January 2012.We identified 407 macrobenthic organism species:64 macroalgae(15.72%of total species);123 Arthropoda(30.22%);107 Mollusca(26.29%);67 Annelida(16.46%);15 Cnidaria(3.69%);14 Echinodermata(3.44%);8 Porifera(1.97%);4 Chordata(0.98%);2 Urochorda(0.49%);and 1 each of Echiura,Sipunculida and Angiospermae(0.25%).Arthropods,mollusks,annelids,and macroalgae were four main groups in the benthic organism community and accounted for 88.70%of the total species.In terms of abundance of biomass,there were 15 dominant species,including 8 macroalgal,5 mollusk and 2 arthropod species.The species diversity indices ranged from 1.21 to 4.42 with an average of 2.80;the annual average of evenness was 0.47.Species richness indices varied from 2.97 to 7.24(average 4.97);and Simpson dominance indices varied from 0.20 to 0.92 in annual average of 0.75.Macroalgal distribution showed clear vertical zonation and seasonal changes.The number of macroalgal species found in the high tide zone,upper middle tide zone,middle tide zone,lower middle tide zone,low tide zone,and below low tide zone were 1,8,10,16,22,and 32,respectively.Biomass among the benthic organisms,macroalgae and crustaceans had significant positive correlation(P<0.05)with the coefficients of 0.802,0.894,and 0.592,respectively.Macroalgal biomass showed a clearly negative correlation with the concentration of dissolved inorganic nitrogen(DIN)(R=0.486,P<0.05).During the winter and spring,when macroalgae were growing vigorously,DIN reached the lowest level in seawater and displayed a clear weak correlation between macroalgal growth and the nutrient concentration.Caixue ZHANG Weinan ZHOU Xingli SUN Sheng KE Yaoqian LIU Zhiguang SONG 2021Journal of Oceanology and Limnology2021,39,2:0
16Inactivated SARS-CoV-2 booster vaccine enhanced immune responses in patients with chronic liver diseases显示文摘Chronic liver disease(CLD)entails elevated risk of COVID-19 severity and mortality.The effectiveness of the booster dose of inactivated SARS-CoV-2 vaccine in stimulating antibody response in CLD patients is unclear.Therefore,we conducted a cross-sectional study involving 237 adult CLD patients and 170 healthy controls(HC)to analyze neutralizing antibodies(NAbs)against SARS-CoV-2 prototype and BA.4/5 variant,anti-receptor binding domain(RBD)IgG,and total anti-SARS-CoV-2 antibodies.Serum levels of the total anti-SARS-CoV-2 antibodies,anti-RBD IgG and inhibition efficacy of NAbs were significantly elevated in CLD patients after the booster dose compared with the pre-booster dose,but were relatively lower than those of HCs.Induced humoral responses decreased over time after booster vaccination.The neutralization efficiency of the serum against BA.4/5 increased but remained below the inhibition threshold.All four SARS-CoV-2 antibodies,including total anti-SARS-CoV-2 antibodies,anti-RBD IgG and NAbs against prototype and BA.4/5,were lower in patients with severe CLD than those with non-severe CLD.After booster shot,age and time after the last vaccine were the risk factors for seropositivity of NAb against BA.4/5 in CLD patients.Additionally,white blood cell counts and hepatitis B core antibodies were the protective factors,and severe liver disease was the risk factor associated with seropositivity of total anti-SARS-CoV-2 antibodies.Overall,our data uncovered that antibody responses were improved in CLD patients and peaked at 120 days after the booster vaccines.All antibodies excepting total anti-SARS-CoV-2 antibodies declined after peak.CLD patients exhibited impaired immunologic responses to vaccination and weakened NAbs against BA.4/5,which hindered the protective effect of the booster shot against Omicron prevalence.Cellular immune responses should be further evaluated to determine the optimal vaccine regimen for CLD patients.Yongmei Liu Jianhua Lu Haoting Zhan Wenfang Yuan Xiaomeng Li Haiyan Kang Haolong Li Yongliang Chen Linlin Cheng Xingli Sun Haojie Zheng Wei Wang Erhei Dai Yongzhe Li 2023Virologica Sinica2023,38,5:0
17Construction of Food Web Model for Liusha Bay-Based on Stable Isotope Analysis显示文摘To investigate the food web structure of Liusha Bay,the δ13C and δ15N values of various organisms collected in Liusha Bay were measured via stable isotope technique.Based on the calculated δ15N value,the correlation between stable isotope ratio and trophic level were established to predict the trophic levels of shrimps,crabs,cephalopods and fishes.By comparing the analysis results of stomach contents of 24 organisms,two methods gave a similar consistence in approximately 71% of organisms within a 0.5 trophic level.It is concluded that stable isotope technique could be an effective method for studying ocean food web trophic level.Yang Guohuan Hou Xiuqiong Sun Xingli Chen Chunliang 2015Animal Husbandry and Feed Science2015,7,1:0
