| 2 | Study of the ionospheric anomaly before the Wenchuan earthquake显示文摘The behavior of the ionosphere before the Wenchuan earthquake is analyzed with the global TEC and ionospheric foF2 observed at Xiamen. It can be found from TEC maps that in the afternoon (16―18LT) on May 9, 2008, 3 days before the earthquake, there is an enhancement of TEC with an amplitude of 10―15 TECU appearing in the east-south direction of Wenchuan, and another enhancement appears at the conjugate region of the Southern Hemisphere with an amplitude of 10 TECU, but no obvious in-crement or decrement can be seen in other regions on global scale. It can also be found that on May 6 (6 days before the great earthquake), there is a decrement of TEC with small amplitude of 4TECU and larger area with 80° along the longitude in southern China, and there is no synchronous decrement observed at the conjugate region of the Southern Hemisphere. There are also many anomalies ob-served by ionosondes across China. The result shows that foF2 and TEC abnormally increased, which is different from pervious results that ionospheric parameters decreased prior to earthquakes. Pre-liminary results suggest that the enhancement on May 9 maybe has a close relationship with the pos-sible enhancement of ionospheric electric fields, and it may be an ionospheric precursor of earth-quakes. Whereas the decrement on May 6 may be attributed to the geomagnetic disturbance appearing on May 5. | YU Tao MAO Tian WANG YunGang WANG JingSong | 2009 | Chinese Science Bulletin2009，54，6： | 20 |
| 3 | Land surface temperature retrieval for arid regions based on Landsat-8 TIRS data:a case study in Shihezi,Northwest China显示文摘Scientific interest in geophysical information about land surface temperature(LST) is ever increasing, as such information provides a base for a large number of applications, including environmental and agricultural monitoring. Therefore, the research of LST retrieval has become a hot topic. Recent availability of Landsat-8 satellite imagery provides a new data source for LST retrieval. Hence, exploring an adaptive method with reliable accuracy seems to be essential. In this study, basing on features of Landsat-8 TIRS thermal infrared channels, we re-calculated parameters in the atmospheric transmittance empirical models of the existing split-window algorithm, and estimated the ground emissivity with the help of the land cover classification map of the study area. Furthermore, a split-window algorithm was rebuilt by virtual of the estimation model of the updated atmospheric transmittance and the ground emissivity, and then a remote sensing retrieval for the LST of Shihezi city in Xinjiang Uygur autonomous region of Northwest China was conducted on the basis of this modified algorithm. Finally, precision validation of the new model was implemented by using the MODIS LST products. The results showed that the LST retrieval from Landsat-8 TIRS data based on our algorithm has a higher credibility, and the retrieved LST is more consistent with the MODIS LST products. This indicated that the modified algorithm is suitable for retrieving LST with competitive accuracy. With higher resolutions, Landsat-8 TIRS data may provide more accurate observation for LST retrieval. | Lei YANG YunGang CAO XiaoHua ZHU ShengHe ZENG GuoJiang YANG JiangYong HE XiuChun YANG | 2014 | Journal of Arid Land2014，6，6： | 17 |
| 4 | Enhancement in wheat leaf photophosphorylation and photosynthesis by spraying low concentration of NaHSO_3显示文摘Spraying 1-2 mmol/L NaHSO3 on the leaf of wheat results in enhancement of photosynthesis in leaves for about 3 d. The amount of ATP has been increased and the millisecond delayed light emission of the leaves has been enhanced, showing that the transmembrane proton motive force related to photophosphorylation is increased. Spraying PMS (a cofactor catalyzing cycle photophosphorylation) and NaHSO3 separately or together on the leaves, 20% increase in photosynthesis has been observed in all the treatments. There is no additive effect when a mixture is applied, suggesting that the mechanism for NaHSO3 promotion of photosynthesis is similar to PMS, and both of them enhance the supply of ATP. | WANG Hongwei, WEI Jiamian & SHEN Yungang (SHEN Yun Kang)Shanghai Institute of Plant Physiology, Chinese Academy of Sciences, Shanghai 200032, China | 2000 | Chinese Science Bulletin2000，45，14： | 15 |
| 5 | Global stabilization by output feedback for a class of nonlinear systems with uncertain control coefficients and unmeasured states dependent growth显示文摘This paper considers the problem of global stabilization by output feedback for a class of nonlinear systems with uncertain control coefficients and with unmeasured states dependent growth. Mainly due to the uncertain control coefficients,the prob-lem has remained unsolved and its major difficulty stems from the inapplicability of the commonly used high-gain like observer. By introducing an appropriate state transformation and a thoroughly novel observer based on high-gain K-filters,the backstepping design approach is successfully proposed to the output-feedback con-troller for this class of systems. It is shown that the global asymptotic stability of the closed-loop system can be guaranteed by the appropriate choice of the control pa-rameters. | LIU YunGang | 2008 | Science in China(Series F)2008，51，10： | 14 |
| 6 | A new approach to adaptive control design without overparametrization for a class of uncertain nonlinear systems显示文摘This paper considers the globally stabilizing adaptive controller design for a class of more general uncertain high-order nonlinear systems with unknown control coefficients.Although the existing literature has solved the problem,for n-dimensional systems,the existing methods need at least n + 1 dynamic updating laws for the unknown parameters to construct the stabilizing adaptive controller;that is,the dimension of the dynamic compensator is not less than n + 1,and therefore,there exists serious overparametrization.In this paper,by defining some new unknown parameters which need dynamic updating,also by using adding a power integrator and related adaptive technique,the overparametrization is successfully solved and a new approach is given to design stabilizing adaptive controller based on only one parameter updating law.A simulation example is finally provided to demonstrate the validness of the proposed approach. | ZHANG Jian LIU YunGang | 2011 | Science China(Information Sciences)2011，54，7： | 13 |

| 8 | Global practical tracking by output-feedback for nonlinear systems with unknown growth rate显示文摘This paper is devoted to the global practical tracking by output-feedback for a class of uncertain nonlinear systems with only the tracking error measurable.Different from the closely related works,the systems have unmeasured states dependent growth with unknown constant rate,and the reference signal,as well as its first order derivative,has unknown bound.Mainly because of these,the tracking problem can hardly be solved by straightforwardly extending the existing results.In the paper,motivated by the related stabilization results,and flexibly using the ideas of universal control and dead zone,an adaptive output-feedback controller is designed to make the tracking error prescribed arbitrarily small after a finite time while keeping all the states of the closed-loop system bounded.A numerical example demonstrates the effectiveness of the theoretical results. | YAN XueHua LIU YunGang | 2011 | Science China(Information Sciences)2011，54，10： | 11 |
| 9 | Identification and Typing of Respiratory Adenoviruses in Guangzhou, Southern China Using a Rapid and Simple Method显示文摘Human adenoviruses (HAdVs), especially HAdV-B3, -E4 and -B7, are associated with Acute Respiratory Disease in Chinese children, and occasionally in adults. In order to establish and document the profiles of the respiratory adenovirus pathogen among children in Guangzhou, Southern China, a rapid, simple and practical method for identification and typing of respiratory adenoviruses was developed and evaluated. One pair of universal PCR primers was designed according to the conserved region of the hexon gene, which can detect not only HAdV-B3, -E4 and -B7, but also HAdV-B14, -F40 and -F41, with a specific 300bp PCR product. Three pairs of type-specific PCR primers were also designed according to the hypervariable regions of the hexon gene to type HAdV-B3, -E4 and -B7 by three independent PCR reactions, making it easy to optimize the PCR conditions. By using this method, one hundred throat swab specimens collected during Oct 2010 to Dec 2011 and suspected of being positive for adenoviral infection were identified and typed for adenoviruses. Of these samples, fifty-five were adenovirus-positive. The most common HAdV type was HAdV-B3, identified in 92.7% of samples, which is not only consistent with the data reported in 2004-2006, but also consistent with the recent report in Hangzhou, eastern China, indicating that HAdV-B3 has been circulating in Guangzhou, and maybe in eastern China, for many years. The method for the respiratory adenovirus identification and typing we developed is rapid, simple and practical, which has a potential in the real-time surveillance of circulating adenovirus strains and also to provide etiological evidence for the adenovirus-relative disease control and prevention in China. | Guiyuan Han Hongling Niu Suhui Zhao Bing Zhu Changbing Wang Yungang Liu Mingjie Zhang Shu Yang Feitong Liu Chengsong Wan Qiwei Zhang | 2013 | Virologica Sinica2013，28，2： | 10 |
| 10 | The role of chloroplast NAD(P)H dehydrogenase in protection of tobacco plant against heat stress显示文摘After incubation at 42℃ for more than 48 h, brown damages occurred on the stems of tobacco (Nicotiana tabacum L.) ndhC-ndhK-ndhJ deletion mutant (?ndhCKJ), followed by wilt of the leaves, while less the phenotype was found in its wild type (WT). Analysis of the kinetics of post-illumination rise in chlorophyll fluorescence indicated that the PSI cyclic electron flow and the chlororespiration mediated by NAD(P)H dehydrogenase (NDH) was significantly enhanced in WT under the high temperature. After leaf disks were treated with methyl viologen (MV), photosynthetic apparatus of ?ndhCKJ exhibited more severe photo-oxidative damage, even bleaching of chlorophyll. Analysis of P700 oxidation and reduction showed that the NDH mediated cyclic electron flow probably functioned as an electron competitor with Mehler reaction, to reduce the accumulation of reactive oxygen species (ROS). When leaf disks were heat stressed at 42℃ for 6 h, the photochemical activity declined more markedly in ?ndhCKJ than in WT, accompanied with more evident decrease in the amount of soluble Rubisco activase. In addition, the slow phase of millisecond-delayed light emission (ms-DLE) of chlorophyll fluorescence indicated that NDH was involved in the building-up of transthy-lakoid proton gradient (?pH), while the consumption of ?pH was highly inhibited in ?ndhCKJ after heat stress. Based on the results, we supposed that the cyclic electron flow mediated by NDH could be stimulated under the heat stressed conditions, to divert excess electrons via chlororespiration pathway, and sustain CO2 assimilation by providing extra ?pH, thus reducing the photooxidative damage. | WANG Peng YE Jiyu SHEN Yungang MI Hualing | 2006 | Science China(Life Sciences)2006，49，4： | 8 |
| 11 | How Unique is ′China Model′: A Review of Theoretical Perspectives on China′s Urbanization in Anglophone Literature显示文摘As a major aspect of the ′China Model′, urbanization in China is being heatedly discussed in the Anglophone literature in the last two decades. By considering China′s urbanization as a ′testing ground′ of ′western′ theories, these studies are important for the understanding of China′s ongoing urban restructuring and exchanging knowledge with ′western′ insights. Based on a survey of existing studies, this paper identifies various endogenous and exogenous concepts and explanations of China′s urbanization. It is suggested that China′s urbanization is mainly driven by a combination of political decentralization and neoliberalization with various forms of social stratification and mobility. However, it is argued that the distinctness of the ′China Model′, which is usually used to support the legitimacy of studies of China′s urbanization, has led to many controversial arguments and diminished the due contributions of Chinese scholars in the knowledge production of China′s urbanization. To consolidate the legitimacy of studies on China′s urbanization and enhance the roles of Chinese scholars, we suggest future studies to pay more attentions to the fundamental theories with looser constraints and ′true questions′ on China′s urbanization. | WANG Fenglong LIU Yungang | 2015 | Chinese Geographical Science2015，25，1： | 8 |
| 12 | Using the GPS observations to reconstruct the ionosphere three-dimensionally with an ionospheric data assimilation and analysis system(IDAAS)显示文摘Using an international reference ionosphere(IRI)model as a background ionosphere and applying the Kalman filter to update the state with observations,we develop an ionosphere data assimilation analysis system(IDAAS)to reconstruct a three-dimensional(3D)ionosphere with the GPS slant TEC and ionosonde data over east-south Asia.The preliminary results with the GPS data collected over east-south Asia on 30 June 2005 showed that inversed slant TEC has very good correlation with the observations both for the GPS sites being and not being involved in reconstruction.The inversed NmF2 and vertical TEC both demonstrate great improvement of agreement with those observed from ionosondes and TOPEX satellite independently. | YU Tao MAO Tian WANG YunGang ZENG ZhongCao WANG JingSong FANG HanXian | 2014 | Science China(Technological Sciences)2014，57，11： | 6 |
| 13 | Tomography of the dynamic stress coefficient for stress wave prediction in sedimentary rock layer under the mining additional stress显示文摘In this study,the tomography of dynamic stress coefficient(TDSC)was established based on a mechanical model of stress wave propagation in bedding planes and a mathematical model of the stress wave attenuation in rock masses.The reliability of the TDSC was verified by a linear bedding plane model and field monitoring.Generally,the TDSC in the dynamic stress propagation of bedding planes increases with the following conditions:(1)the increase of the normal stiffness of the bedding plane,(2)the increase of the incident angle of the stress wave,(3)the decrease of the incident frequency of the stress wave,or(4)the growth of three ratios(the ratios of rock densities,elastic moduli,and the Poisson’s ratios)of rocks on either side of bedding planes.The additional stress weakens TDSC linearly and slowly during the stress wave propagation in bedding planes,and the weakening effect increases with the growth of the three ratios.Besides,the TDSC decreases exponentially in the rock mass as propagation distance increases.In a field case,the TDSC decreases significantly as vertical and horizontal distances increase and its wave range increases as vertical distance increases in the sedimentary rock layers. | Wenlong Shen Guocang Shi Yungang Wang Jianbiao Bai Ruifeng Zhang Xiangyu Wang | 2021 | International Journal of Mining Science and Technology2021，31，4： | 5 |
| 14 | Administrative Urbanization and City-making in Post-reform China: A Case Study of Ordos City, Inner Mongolia显示文摘In post-reform China, local governments, instead of the central state, have become major promoters of urbanization. Differing from the existing literature based on Western theories, this article argues that a localized perspective, ‘administrative urbanization', can provide a contextual explanation for the mechanism of urbanization in the reform era. The case study of Ordos indicates that new town construction, especially in the inland area, has become the main strategy for investment attraction and economic development. The local government has played a dominant role in this construction through a series of administrative measures, including avoidance of central state regulations, land leasing, high standard infrastructure construction, relocation policies and industrial attraction. This article also explores the issue of unsustainability in the new town, and identifies that underdeveloped industrialization, slow population agglomeration and real estate bubbles are primary threats to the sustainability of administrative urbanization. | YIN Guanwen LIU Yungang | 2017 | Chinese Geographical Science2017，27，6： | 4 |
| 15 | Global practical tracking with prescribed transient performance for inherently nonlinear systems with extremely severe uncertainties显示文摘This paper considers the global practical tracking for a class of uncertain nonlinear systems. Remarkably, the systems under investigation admit rather inherent nonlinearities, and especially allow arguably the most severe uncertainties: unknown control directions and non-parametric uncertainties. Despite this,a refined tracking objective, rather than a reduced one, is sought. That is, not only pre-specified arbitrary tracking accuracy is guaranteed, but also certain prescribed transient performance(e.g., arrival time and maximum overshoot) is ensured to better meet real applications. To solve the problem, a new tracking scheme is established, crucially introducing delicate time-varying gains to counteract the severe uncertainties and guarantee the prescribed performance. It is shown that the designed controller renders the tracking error to forever evolve within a prescribed performance funnel, through which the desired tracking objective is accomplished for the systems. Particularly, by subtly specifying the funnel, global fixed-time practical tracking(i.e., that with prescribed arrival time) and semiglobal practical tracking with prescribed maximal overshoot can be achieved for the systems. Moreover, the tracking scheme remains valid in the presence of rather less-restrictive unmodeled dynamics. | Fengzhong LI Yungang LIU | 2019 | Science China(Information Sciences)2019，62，2： | 4 |

According to the clustering results,based on geographical origins and genetic backgrounds,122 materials were clustered into 14 categories. Dendrogram based on Nei's genetic distance revealed complex genetic relationships among wild tea germplasm resources in Yunnan Province. This study provided certain reference for subsequent preservation,development and research of wild tea germplasm resources in China. | Meng ZHOU Youyong LI Xuemei SUN Jiajin WANG Jin XIE Hao CHENG Yungang WANG Benying LIU | 2015 | Agricultural Biotechnology2015，4，1： | 4 |
| 17 | Electrochemical Deposition and Nucleation of Aluminum on Tungsten in Aluminum Chloride-Sodium Chloride Melts显示文摘Electrochemical deposition and nucleation of aluminum on tungsten electrode from AlCl_3-NaCl melts were studied by cyclic voltammetry,chronopotentiometry and chronoamperometry.Cyclic voltammetry and chronopo- tentiometry analyses showed that Al(Ⅲ) was reduced at 200℃in two consecutive steps in an electrolyte of molten AlCl_3-NaCl system with a composition 52:48 molar ratio.The current-time characteristics of nucle- ation aluminum on tungsten showed a strong dependence on overpotentials.Chronoamperometry showed that the deposition process of aluminum on tungsten was controlled by an instantaneous nucleation with a hemispherical diffusion-controlled growth mechanism.The results could lead to a better understanding of the AlCl_3-NaCl melt system that has technological importance in electrodeposition of metals as well as in rechargeable batteries. | Zhaowen WANG Hongmin KAN Zhongning SHI Bingliang GAO Yungang BAN Xianwei HU | 2008 | Journal of Materials Science & Technology2008，24，6： | 4 |

| 20 | Idiopathic Orbital Inflammation Associated with Panuveitis in an Adult and a Review of the Literature显示文摘Purpose:To report an unusual case of idiopathic orbital inflammation associated with panuveitis. Case report:We report a case of a 47-year-old female with a history of uveitis who presented with abrupt and painful prop tosis with complete vision loss unresponsive to antibiotic therapy.B-scan ultrasonography and magnetic resonance imaging both showed retinal detachment and an orbital space-occupying mass. The patient underwent orbitotomy and the diagnosis of idiopathic orbital inflammation was confirmed by histopathology. Anterior uveitis is rarely seen in idiopathic orbital inflammation in adults. We report for the first time an unusual case of idiopathic orbital inflammation associated with panuveitis. Conclusion:Inflammation involving both the eye and the orbit is rarely seen in adults. Idiopathic orbital inflammation and panuveitis may share a similar mechanism in this case.
