| 1 | Exotic origin of the Chinese continental shelf: new insights into the tectonic evolution of the western Pacific and eastern China since the Mesozoic显示文摘The effect of paleo-Pacific subduction on the geological evolution of the western Pacific and continental China is likely complex. Nevertheless, our analysis of the distribution of Mesozoic granitoids in the eastern continental China in space and time has led us to an interesting conclusion: The basement of the continental shelf beneath East and South China Seas may actually be of exotic origin geologically unrelated to the continental lithosphere of eastern China. By accepting the notion that the Jurassic–Cretaceous granitoids in the region are genetically associated with western Pacific subduction and the concept that subduction may cease to continue only if the trench is being jammed, then the termination of the granitoidmagmatism throughout the vast region at *88 ± 2 Ma manifests the likelihood of ‘‘sudden'', or shortly beforehand(*100 Ma), trench jam of the Mesozoic western Pacific subduction. Trench jam happens if the incoming‘‘plate'' or portion of the plate contains a sizeable mass that is too buoyant to subduct. The best candidate for such a buoyant and unsubductable mass is either an oceanic plateau or a micro-continent. We hypothesize that the basement of the Chinese continental shelf represents such an exotic, buoyant and unsubductable mass, rather than seaward extension of the continental lithosphere of eastern China. The locus of the jammed trench(i.e., the suture) is predictably located on the shelf in the vicinity of, and parallel to, the arc-curved coastal line of the southeast continental China. It is not straightforward to locate the locus in the northern section of the East China Sea shelf because of the more recent(\20 Ma) tectonic re-organization associated with the opening of the Sea of Japan. We predict that the trench jam at *100 Ma led to the re-orientation of the Pacific plate motion in the course of NNW direction as inferred from the age-progressive Emperor Seamount Chain of Hawaiian hotspot origin(its oldest unsubdued Meiji and Detroit seamounts are *82 Ma),making the boundary between the Pacific plate and the newly accreted plate of eastern Asia a transform fault at the location east of the continental shelf of exotic origin. This explains the apparent *40 Myr magmatic gap from *88to *50 Ma prior to present-day western Pacific subduction initiation. We propose that basement penetration drilling on well-chosen sites is needed to test the hypothesis in order to reveal the true nature of the Chinese continental shelf basement. This testing becomes critical and cannot longer be neglected in order to genuinely understand the tectonic evolution of the western Pacific and its effect on the geology of eastern China since the Mesozoic, includingthe cratonic lithosphere thinning, related magmatism/mineralization, and the mechanism of the subsequent South China Sea opening, while also offering novel perspectives on aspects of the plate tectonics theory. We also suggest the importance of future plate tectonic reconstruction of the western Pacific to consider the nature and histories of the Chinese continental shelf of exotic origin as well as the probable transform plate boundary from *100 to*50 Ma. Effort is needed to reveal the true nature and origin of the *88 ± 2 Ma granitic gneisses in Taiwan and the 110–88 Ma granitoids on the Hainan Island. | Yaoling Niu Yi Liu Qiqi Xue Fengli Shao Shuo Chen Meng Duan Pengyuan Guo Hongmei Gong Yan Hu Zhenxing Hu Juanjuan Kong Jiyong Li Jinju Liu Pu Sun Wenli Sun Lei Ye Yuanyuan Xiao Yu Zhang | 2015 | Science Bulletin2015,60,18: | 32 |

| 3 | DISTRIBUTION OF CARBONACEOUS AEROSOL DURING SPRING 2005 OVER THE HORQIN SANDLAND IN NORTHEASTERN CHINA显示文摘The objective of this study was to characterize the elemental carbon and organic carbon (EC and OC, respectively) content of aerosol particles (PM2.5) collected at Tongliao, a site in the Horqin Sandland of northeastern China. During spring 2005, the PM2.5 mass concentration was 126±71 μg?m-3, with higher dust concentrations during five dust storms than on non-dusty days (255±77 vs. 106±44 μg?m-3). The average OC and EC concentrations in PM2.5 de-termined by a thermal/optical reflectance method were 15.7±7.3 μg?m-3 and 3.3±1.7 μg?m-3, respectively, and carbona-ceous aerosol accounted for 9.9% of the PM2.5 mass during dust storms compared to 21.7% on normal days. The aver-age ratios of OC to EC during dust storms were similar to those on non-dusty days, and the correlation coefficient be-tween OC and EC was high, 0.86. The high OC/EC ratios, the distributions of eight carbon fractions, and the strong rela-tionship between K with OC and EC indicate that rural biomass burning was the dominant contributor to the regional carbonaceous aerosol. | Xuxiang Li Zhenxing Shen Junji Cao Suixin Liu Chongshu Zhu Ting Zhang | 2006 | China Particuology2006,4,6: | 10 |
| 4 | Molecular mapping of QTLs for root response to phosphorus deficiency at seedling stage in wheat (Triticum aestivum L.)显示文摘Phosphorus (P) deficiency in the soil is one of the major abiotic stresses that limit plant growth and crop productivity throughout the world. Development of cultivars with improved P-deficiency tolerance is an efficient strategy for sustainable agriculture. Plant roots play an important role in crop growth and development, especially in nutrient uptake and improvement of P-efficiency. Mapping quantitative trait loci (QTLs) for root traits and their response to low P stress at seedling stage will facilitate the development of P-efficient wheat cultivars. In this study, 30 QTLs (LOD>2.0) were mapped for the three root traits, such as root length, root number and root dry matter under different P supply conditions and their response to P-stress. These QTLs were distributed on 14 chromosomes, with each of the 5 QTLs explaining more than 10% phenotype variance. Analyses showed that root traits and their response to P-deficiency were controlled by different QTLs. In addition, alleles with positive effects were separated on both parents, and wheat cultivars with improved P-efficiency could be developed by accumulating these positive effect alleles together. | Li Zhenxing Ni Zhongfu Peng Huiru Liu Zhiyong Nie Xiuling Xu Shengbao Liu Gang Sun Qixin | 2007 | Progress in Natural Science:Materials International2007,17,10: | 8 |
| 5 | Highly conductive dodecaborate/MXene composites for high performance supercapacitors显示文摘With the increasingly prominent energy and environmental issues,the supercapacitors,as a highly efficient and clean energy conversion and storage devices,meet the requirements well.However,it is still a challenge to enhance the capacitance and energy density of supercapacitors.A novel and highly conductive dodecaborate/MXene composites have been designed for high performance supercapacitors.The surface charge property of MXene was modified by a simple ultrasonic treatment with ammonium ion,and the dodecaborate ion can be inserted into the inner surface of MXene by electrostatic adsorption.Due to the unique icosahedral cage conjugate structure formed by the B-B bond and the highly delocalized three-dimensionalπbond structure of the electrons,the negative charge is delocalied on the whole dodecaborate ion,which reduces the ability to bind to cations.Therefore,the cations can move easily,and the dodecaborate can act as a“lubricant”for ion diffusion between the MXene layers,which significantly improves the ion transfer rate of supercapacitors.The dodecaborate/MXene composites can achieve an extremely high specific capacitance of 366 F.g^-1 at a scan rate of 2 mV.s^-1,which is more than eight times higher than that of MXene(43 F1-)at the same scan rate.Our finding provides a novel route on the fabrication of the high performance supercapacitors. | Zhenxing Li Chang Ma Yangyang Wen Zhiting Wei Xiaofei Xing Junmei Chu Chengcheng Yu Kaili Wang Zhao-Kui Wang | 2020 | Nano Research2020,13,1: | 7 |
| 6 | Research progresses on Cherenkov and transit-time high-power microwave sources at NUDT显示文摘Research progresses on Cherenkov and transit-time high-power microwave(HPM)sources in National University of Defense Technology(NUDT)of China are presented.The research issues are focused on the following aspects.The pulse-shortening phenomenon in O-type Cerenkov HPM devices is suppressed.The compact coaxial relativistic backward-wave oscillators(RBWOs)at low bands are developed.The power efficiency in M-Type HPM tubes without guiding magnetic field increased.The power capacities and power efficiencies in the triaxial klystron amplifier(TKA)and relativistic transit-time oscillator(TTO)at higher frequencies increased.In experiments,some exciting results were obtained.The X-band source generated 2 GW microwave power with a pulse duration of 110 ns in 30 Hz repetition mode.Both L-and P-band compact RBWOs generated over 2 GW microwave power with a power efficiency of over 30%.There is approximately a 75% decline of the volume compared with that of conventional RBWO under the same power capacity conditions.A 1.755 GHz MILO produced 3.1 GW microwave power with power efficiency of 10.4%.A 9.37 GHz TKA produced the 240 MW microwave power with the gain of 34 dB.A 14.3 GHz TTO produced 1 GW microwave power with power efficiency of 20%. | Jiande Zhang Xingjun Ge Jun Zhang Juntao He Yuwei Fan Zhiqiang Li Zhenxing Jin Liang Gao Junpu Ling Zumin Qi | 2016 | Matter and Radiation at Extremes2016,1,3: | 7 |
| 7 | Fabrication technique of micro/nano-scale speckle patterns with focused ion beam显示文摘The fabrication technique of micro/nano-scale speckle patterns with focused ion beam (FIB) system is studied for digital image correlation (DIC) measurement under a scanning electron microscope (SEM).The speckle patterns are fabricated by directly etching the counterpart of the specimen to the black part of a template.Mean intensity gradient is used to evaluate the quality of these SEM images of speckle patterns fabricated based on different templates to select an optimum template.The pattern size depending on the displacement measurement sensitivity is adjusted by altering the magnification of FIB according to the relation curve of the etching size versus magnification.The influencing factors including etching time and ion beam current are discussed.Rigid body translation tests and rotation tests are carried out under SEM to verify the reliability of the fabricated speckle patterns.The calculated values are in good agreement with the imposed ones. | LI YanJie XIE HuiMin LUO Qiang GU ChangZhi HU ZhenXing CHEN PengWan ZHANG QingMing | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,6: | 7 |
| 8 | The Anti-allergic Activity of Polyphenol Extracted from Five Marine Algae显示文摘Natural polyphenol has been widely believed to be effective in allergy remission. Currently, most of the natural polyphenol products come from terrestrial sources such as tea, grape seeds among others, and few polyphenols have been developed from algae for their anti-allergic activity. The aim of the study was to screen some commercial seaweed for natural extracts with anti-allergic activity. Five algae including Laminaria japonica, Porphyra sp., Spirulina platensis, Chlorella pyrenoidosa and Scytosiphon sp. were extracted with ethanol, and the extracts were evaluated for total polyphenol contents and anti-allergic activity with the hyaluronidase inhibition assay. Results showed that the total polyphenol contents in the ethanol extracts ranged from 1.67% to 8.47%, while the highest was found in the extract from Scytosiphon sp. Hyaluronidase inhibition assay showed that the extracts from Scytosiphon sp. had the lowest IC50, 0.67 mg m L-1, while Chlorella pyrenoidosa extract had the highest IC50, 15.07 mg m L-1. The anti-allergic activity of Scytosiphon sp. extract was even higher than the typical anti-allergic drug Disodium Cromoglycate(DSCG)(IC50 = 1.13 mg m L-1), and was similar with natural polyphenol from Epigallocatechin gallate(EGCG)(IC50 = 0.56 mg m L-1). These results indicated that the ethanol extract of Scytosiphon sp. contains a high concentration of polyphenol with high anti-allergic activity. Potentially Scytosiphon sp. can be developed to a natural anti-allergic compound for allergy remission. | CHEN Yu LIN Hong LI Zhenxing MOU Quangui | 2015 | Journal of Ocean University of China2015,14,4: | 7 |
| 9 | Perspective of hydrogen energy and recent progress in electrocatalytic water splitting显示文摘As a secondary energy with great commercialization potential,hydrogen energy has been widely studied due to the high calorific value,clean combustion products and various reduction methods.At present,the blueprint of hydrogen energy economy in the world is gradually taking shape.Compared with the traditional high-energy consuming methane steam reforming hydrogen production method,the electrocatalytic water splitting hydrogen production stands out among other process of hydrogen production owning to the mild reaction conditions,high-purity hydrogen generation and sustainable production process.Basing on current technical economy situation,the highly electric power cost limits the further promotion of electrocatalytic water splitting hydrogen production process.Consequently,the rational design and development of low overpotential and high stability electrocatalytic water splitting catalysts are critical toward the realization of low-cost hydrogen production technology.In this review,we summarize the existing hydrogen production methods,elaborate the reaction mechanism of the electrocatalytic water splitting reaction under acidic and alkaline conditions and the recent progress of the respective catalysts for the two half-reactions.The structure-activity relationship of the catalyst was deep-going discussed,together with the prospects of electrocatalytic water splitting and the current challenges,aiming at provide insights for electrocatalytic water splitting catalyst development and its industrial applications. | Yixuan Gong Jiasai Yao Ping Wang Zhenxing Li Hongjun Zhou Chunming Xu | 2022 | Chinese Journal of Chemical Engineering2022,35,3: | 7 |
| 10 | Would integrated Western and traditional Chinese medicine have more benefits for stroke rehabilitation? A systematic review and meta-analysis显示文摘Background Stroke is a major cause of death or long-term disability worldwide.Many patients with stroke receive integrative therapy consisting of Western medicine(WM)and routine rehabilitation in conjunction with Chinese medicine(CM),such as acupuncture and Chinese herbal medicine.However,there is no available evidence on the effectiveness of the combined use of WM and CM interventions in stroke rehabilitation.Aims The purpose of this meta-analysis is to evaluate the results of all individual studies to assess the combined use of CM and WM in stroke rehabilitation compared with WM only.Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed.MEDLINE,EMBASE,Cochrane and China National Knowledge Infrastructure(CNKI)were searched.The included outcomes were dependency,motor function,depression and swallowing function.Subgroup analysis was performed,and publication bias was assessed using funnel plots.Summary of review 58 studies and 6339 patients were included in the meta-analysis.Subgroup analysis revealed that combined therapy comprising both acupuncture and WM had a superior effect on improving dependency and swallowing function compared with standard WM therapy alone.Potential superiority of combined therapy comprising CM and WM in improving depression compared with standard WM therapy was also found.Conclusions Our results indicate that the combined use of CM and WM could be more efficacious in stroke rehabilitation compared with the use of WM therapy alone.However,most studies were short in duration(2 to 4 weeks)and prone to different types of biases,which prevents making any conclusion regarding the long-term effects and raises concerns regarding true efficacy in context of high likelihood of Hawthorn bias.So,more randomised controlled trials with more rigorous design and longer duration of treatment and follow-up need to be conducted to compare WM alone versus WM and CM combined. | Linda LD Zhong Ya Zheng Alexander Y Lau Norman Wong Liang Yao Xingyao Wu Tengteng Shao Zhenxing Lu Huijuan Li Chun Sum Yuen Jianwen Guo Suzanne Lo Janita Chau Kam Wa Chan Bacon Fung Leung Ng Zhaoxiang Bian Edwin Chau-leung Yu | 2022 | Stroke & Vascular Neurology2022,7,1: | 7 |
| 11 | Control of neotectonic movement on hydrocarbon accumulation in the Kuqa Foreland Basin,west China显示文摘Neotectonic movement refers to the tectonic movement that has happened since the Cenozoic,which is the latest movement. It has the most important influence on the basins in west China,especially on the hydrocarbon accumulation in the western foreland basins. We determined the time of neotectonic movement in the Kuqa Foreland Basin,which began from the Neogene,and analyzed the patterns of movement,which were continuous and fast subsidence in the vertical direction and intense lateral compression. The structure styles are that the faulting is weakened and the folding is strengthened gradually from north to south. We studied the control of neotectonic movement on the hydrocarbon accumulation process and model in the Kuqa Foreland Basin with basin simulation technique. The largest subsidence rate of the Kuqa Foreland Basin reached 1,200 m/Ma during the neotectonic movement,leading to rapid maturing of source rock within 5 Ma and a large quantity of hydrocarbon being generated and expelled. The thick neotectonic strata can form high quality reservoirs with the proved gas and oil reserves accounting for 5% and 27% of the total reserves,respectively. 86% of the structural traps were formed in the neotectonic movement period. The faults formed during the neotectonic movement serve as important migration pathways and they exist in the region where the hydrocarbon reservoirs are distributed. Abnormally high pressure caused by the intense lateral compression,thick neotectonic strata deposition and rapid hydrocarbon generation provide driving force for hydrocarbon migration. The accumulation elements match each other well over a short period,leading to many large gas fi elds formed later in the Kuqa Foreland Basin. | Jiang Zhenxue Li Lianxia Song Yan Tian Fenghua Zhao Mengjun Wang Haijiang Zhao Zhenxing | 2010 | Petroleum Science2010,7,1: | 6 |
| 12 | Effect of temperature field on solidification structure of pure Al under pulse magneto-oscillation显示文摘This article discusses the effect of temperature field on the Pulse Magneto-Oscillation(PMO) induced solidification refinement of pure aluminium to provide more information for the industrial application of the PMO solidification technology.The temperature field is altered mainly by applied variable cooling conditions and pulse parameters.Experimental results show that the refinement effect in the case of full sand mould applied is weakened with the decreasing of cooling rate,however,in the alternative case,the sand mould whose sand bottom was replaced by a graphite block is favorable to the survival of equiaxed nucleus.The refinement mechanism is discussed in terms of the relationship between temperature field and the formation process of solidified structure.The formation or survival of nucleus depends on both temperature field and Joule heat produced by PMO,both low pulse frequency and high pulse current were experimentally confirmed to be effective;and PMO was demonstrated high potential in industrial application. | Li Bo Yin Zhenxing Gong Yongyong LJ Kefeng Zheng Hongxing Li Renxing Zhai Qijie | 2011 | China Foundry2011,8,2: | 6 |
| 13 | A novel fault section locating method based on distance matching degree in distribution network显示文摘Fault section location of a single-phase grounding fault is affected by the neutral grounding mode of the system, transition resistance, and the blind zone. A fault section locating method based on an amplitude feature and an intelligent distance algorithm is proposed to eliminate the influence of the above factors. By analyzing and comparing the amplitude characteristics of the zero-sequence current transient components at both ends of the healthy section and the faulty section, a distance algorithm with strong abnormal data immune capability is introduced in this paper. The matching degree of the amplitude characteristics at both ends of the feeder section are used as the criterion and by comparing with the set threshold, the faulty section is effectively determined. Finally, simulations using Matlab/Simulink and PSCAD/EMTDC show that the proposed section locating method can locate the faulty section accurately, and is not affected by grounding mode, grounding resistance, or the blind zone. | Zhenxing Li Jialing Wan Pengfei Wang Hanli Weng Zhenhua Li | 2021 | Protection and Control of Modern Power Systems2021,6,1: | 6 |
| 14 | Hydrolyzed seawater pearl tablet modulates the immunity via attenuating Th1/Th2 imbalance in an immunosuppressed mouse model显示文摘OBJECTIVE: To investigate whether Hydrolyzed Seawater Pearl tablet(HSPT) could modulate the Th1/Th2 imbalance in an immunosuppressed mouse model with Th1 to Th2 shift induced by Cyclosporine A(Cs A) which can be used in the clinical treatment of Th2 to Th1 shift diseases, and explore the possible mechanism for the adjuvant therapeutic efficacy of HSPT on recurrent respiratory infections(RRI) and acquired immune deficiency syndrome(AIDS).METHODS: The mice were randomly divided into six groups of five animals each, namely normal group, model group, lentinan polysaccharide tablet(LPT) group and three HPST treated groups. HPST treated groups were administered with HPST(0.51,1.02, 2.04 g/kg) via intragastric gavage(i.g) for 30 consecutive days. LPT used as reference drug for positive control, LPT group was administered with LPT(8.2 mg/kg) for 30 consecutive days. Normal group and model group were received distilled water. The animals in model group, LPT group and HPST treated groups were injected intraperitoneally with Cs A(50 mg/kg) to establish the immunosuppressed mice model with Th1 to Th2 shift on the20 th, 22 nd and 24 th day, one hour after the administration of the respective treatment. Animals were sacrificed one hour after the last administration to collect blood and splenic tissue. The proportion of T cells including CD8+ and CD4+ T cells, Th1 and Th2 in peripheral blood of experimental mice were measured by flow cytometric. The protein level in serum and m RNA level in splenic tissue of experimental mice for interleukin(IL)-2, IL-12, interferon-γ(IFN-γ), IL-4, IL-6, IL-10 and IL-13 were measured by enzyme linked immunosorbent assay and fluorescence quantitative polymerase chain reaction respectively.RESULTS: HSPT elevated the proportion of T cells including both CD8+ and CD4+ T cells, in which the proportion of Th1 and Th2 cells increased, while the ratio of Th1/Th2 cells decreased in peripheral blood of the immunosuppressed mouse model with Th1 to Th2 shift induced by Cs A. Furthermore,HSPT elevated both protein and m RNA level of Th1-type cytokines IL-2 and IFN-γ, while had no significant effect on protein and m RNA level of Th1-type cytokine IL-12 and Th2-type cytokines IL-4, IL-6, IL-10, IL-13 in mouse model.CONCLUSION: Our findings suggest that HSPT can increase proportion of T cells including both CD8+and CD4+T cells and induce Th2 to Th1 shift in both cells and cytokines, which probably was the mechanism to account for the adjuvant therapeutic efficacy of HSPT on RRI and AIDS. | LAN Taijin LUO Xuefei MO Mingyue CHEN Zhenxing LUO Fei HAN Siyin LIU Peng LIANG Zhongxiu ZHANG Ting LI Tianyi YAN Qiangqiang LIN Yong LIN Jiang | 2021 | Journal of Traditional Chinese Medicine2021,41,3: | 6 |
| 15 | Publication trends in studies examining radix notoginseng as a treatment for ischemic brain injury显示文摘Acute ischemic stroke has become a major disease burden with high mortality and morbidity rates. There is a lack of evidence-based medicine confirming the efficacy of common treatments. Panax notoginseng saponins, the main active ingredient of radix notoginseng, have a neuroprotective role in ischemic brain injury, and have been popularized as a maintenance treatment for acute cerebral infarction and its sequelae. We conducted literature searches on the Web of Science, ClinicalTrials.gov, Cochrane Collaboration, CNKI, Wanfang and the China Scientific & Technological Achievements Database and analyzed the experimental and clinical outcomes of studies investigating the use of radix notoginseng in the treatment of ischemic brain injury to improve the understanding of relevant research trends and existing problems. We found that over the past 10 years, China has maintained its interest in Panax notoginseng research, while such studies are scarce on the Web of Science. However, Chinese researchers often focus on the neuroprotective role of radix notoginseng in ischemic brain injury, but there are no large-scale clinical data to confirm its efficacy and safety. There remains a need for more rigorous large-sample randomized controlled clinical trials with long-term follow-up, to determine whether radix notoginseng lowers stroke recurrence and improves patient's quality of life. | Haiping Li Luo Qiang Chunyang Zhang Chaohui Wang Zhenxing Mu Ligang Jiang | 2014 | Neural Regeneration Research2014,9,17: | 5 |
| 16 | Identification and Characterization of a New IgE-binding Protein in Mackerel (Scomber japonicus) by MALDI-TOF-MS显示文摘As fish is one source of the ‘big eight’ food allergens,the prevalence of fish allergy has increased over the past few years.In order to better understand fish allergy,it is necessary to identify fish allergens.Based on the sera from fish-allergenic patients,a 28 kDa protein from local mackerel (Scomber japonicus),which has not been reported as a fish allergen,was found to be reactive with most of the patients’ sera.The 28 kDa protein was analyzed by MALDI-TOF-MS (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry).Mascot search in NCBI database (Date: 08/07/2010) showed that the top protein matched,i.e.triosephosphate isomerase (TPI) from Xiphophorus maculatus and Poecilia reticulata,had a mowse (molecular weight search) score of 98.In addition,TPI from Epinephelus coioides also matched this mackerel protein with a mowse score of 96.Because TPI is con-sidered as an allergen in other non-fish organisms,such as lychee,wheat,latex,archaeopotamobius (Archaeopotamobius sibiriensis) and crangon (Crangon crangon),we consider that it may also be an allergen in mackerel. | WANG Bangping LI Zhenxing ZHENG Lina LIU Yixuan LIN Hong | 2011 | Journal of Ocean University of China2011,10,1: | 5 |

| 18 | CHARACTERISTICS OF CLAY MINERALS IN ASIAN DUST AND THEIR ENVIRONMENTAL SIGNIFICANCE显示文摘The objectives of this research were to characterise the clay minerals composition of soil-derived dust in Northern China and to set up a mineralogical signature to trace their origin. Mineral composition of aerosol particles was investigated at Aksu, Dunhuang, Yulin, Tongliao and Changwu during an intensive field campaign period of ACE-Asia.The results show that the kaolinite (K) to chlorite (C) ratio is sensitive to the regional origin of Asian dust. Western source areas (represented by Aksu) displayed the lowest K/C ratio of 0.3 (average), while it was found to increase up to 0.70(average) upon moving towards northern source areas (represented by Yulin). By studying transported dust in a deposition area representative of the Chinese Loess Plateau, the usefulness of the K/C ratio, when associated with back air-mass trajectories, was found to lie in revealing the origin of the dust. Comparison of the mineralogical data between Asian dust and Sahara dust, shows that the K/C ratio is also an effective signature to identify the source areas on a hemisphere scale. | Zhenxing Shen Xuxiang Li Junji Cao Sandrine Caquineau Yaqiang Wang Xiaoye Zhang | 2005 | China Particuology2005,3,5: | 5 |
| 19 | Cryo-self-assembled silk fibroin sponge as a biodegradable platform for enzyme-responsive delivery of exosomes显示文摘Although advances in protein assembly preparation have provided a new platform for drug delivery during tissue engineering,achieving long-term controlled exosome delivery remains a significant challenge.Diffusion-dominated exosome release using protein hydrogels results in burst release of exosomes.Here,a fibroin-based cryo-sponge was developed to provide controlled exosome release.Fibroin chains can self-assemble into silk I structures under ice-cold conditions when annealed above the glass transition temperature.Exosome release is enzyme-responsive,with rates primarily determined by enzymatic degradation of the scaffolds.In vivo experiments have demonstrated that exosomes remain in undigested sponge material for two months,superior to their retention in fibrin glue,a commonly used biomaterial in clinical practice.Fibroin cryo-sponges were implanted subcutaneously in nude mice.The exosome-containing sponge group exhibited better neovascularization and tissue ingrowth effects,demonstrating the efficacy of this exosome-encapsulating strategy by realizing sustained release and maintaining exosome bioactivity.These silk fibroin cryo-sponges containing exosomes provide a new platform for future studies of exosome therapy. | Muyang Sun Qi Li Huilei Yu Jin Cheng Nier Wu Weili Shi Fengyuan Zhao Zhenxing Shao Qingyang Meng Haifeng Chen Xiaoqing Hu Yingfang Ao | 2022 | Bioactive Materials2022,7,2: | 4 |
| 20 | Finite Frequency Fuzzy H∞Control for Uncertain Active Suspension Systems With Sensor Failure显示文摘This paper investigates the problem of finite frequency fuzzy H_∞ control for uncertain active vehicle suspension systems, in which sensor failure is taken into account. TakagiSugeno(T-S) fuzzy model is established for considered suspension systems. In order to describe the sensor fault effectively, a corresponding model is introduced. A vital performance index,H_∞ performance, is utilized to measure the drive comfort. In the framework of Kalman-Yakubovich-Popov theory, the H_∞ norm from external perturbation to controlled output is optimized effectively in the frequency domain of 4 Hz-8 Hz to enhance ride comfort level. Meanwhile, three suspension constrained requirements, i.e., ride comfort level, manipulation stability,suspension deflection are also guaranteed. Furthermore, sufficient conditions are developed to design a fuzzy controller to guarantee the desired performance of active suspension systems. Finally, the proposed control scheme is applied to a quarter-vehicle active suspension, and simulation results are given to illustrate the effectiveness of the proposed approach. | Zhenxing Zhang Hongyi Li Chengwei Wu Qi Zhou | 2018 | IEEE/CAA Journal of Automatica Sinica2018,5,4: | 4 |
