| 1 | Survey of information security显示文摘The 21st century is the age of information when information becomes an important strategic resource. The information obtaining, processing and security guarantee capability are playing critical roles in comprehensive national power, and information security is related to the national security and social stability. Therefore, we should take measures to ensure the information security of our country. In recent years, momentous accomplishments have been obtained with the rapid development of information security technology. There are extensive theories about information security and technology. However, due to the limitation of length, this article mainly focuses on the research and development of cryptology, trusted computing, security of network, and information hiding, etc. | SHEN ChangXiang ZHANG HuangGuo FENG DengGuo CAO ZhenFu HUANG JiWu | 2007 | Science in China(Series F)2007，50，3： | 39 |

| 3 | Nonlinear balance constraints in 3DVAR data assimilation显示文摘In many applications of 3DVAR, the balance constraints can be considered via two main approaches: weak constraint method which adds penalty terms to the cost function; and proper defi- nition of the background error covariance matrix with non-zero cross-correlation sub-matrices. The weak constraint approach requires determining the weighting matrices of the penalty terms. The background error covariance approach does not require determining those additional weighting ma- trices. However, it is only applicable to those linear or linearized balance constraints. A novel ap- proach is proposed based on the background error covariance approach by generalizing the so-called Derber-Bouttier formulation. An assimilation experiment of estimating temperature and salinity from the sea surface dynamic height observation is given to illustrate the proposed treatments of nonlinear balance constraints. | ZHU Jiang YAN Changxiang | 2006 | Science China Earth Sciences2006，49，3： | 24 |
| 4 | Energy-Theft Detection Issues for Advanced Metering Infrastructure in Smart Grid显示文摘With the proliferation of smart grid research,the Advanced Metering Infrastructure(AMI) has become the first ubiquitous and fixed computing platform. However,due to the unique characteristics of AMI,such as complex network structure,resource-constrained smart meter,and privacy-sensitive data,it is an especially challenging issue to make AMI secure. Energy theft is one of the most important concerns related to the smart grid implementation. It is estimated that utility companies lose more than $25 billion every year due to energy theft around the world. To address this challenge,in this paper,we discuss the background of AMI and identify major security requirements that AMI should meet. Specifically,an attack tree based threat model is first presented to illustrate the energy-theft behaviors in AMI. Then,we summarize the current AMI energy-theft detection schemes into three categories,i.e.,classification-based,state estimation-based,and game theory-based ones,and make extensive comparisons and discussions on them. In order to provide a deep understanding of security vulnerabilities and solutions in AMI and shed light on future research directions,we also explore some open challenges and potential solutions for energy-theft detection. | Rong Jiang Rongxing Lu Ye Wang Jun Luo Changxiang Shen Xuemin(Sherman) Shen | 2014 | Tsinghua Science and Technology2014，19，2： | 22 |
| 5 | Evaluation of a 3dVAR system for the South China Sea显示文摘The authors evaluate a three-dimensional variational (3dVAR) system for the South China Sea (SCS) in this study. The assimilation method applied in the system takes into consideration error correlation along each ground track and uses recursive lter for optimiza- tion. Data from three R/V cruises during the spring and summer of 1998 and the summer of 2000 are used to evaluate the system. The root-mean-square error and bias are reduced signi cantly and when the altimeter data are assimilated, the distribution of the error is much closer to the Gaussian distribution. Precipitation and river discharge in the southwestern SCS are reproduced, and the variability of sea surface height is e ciently transferred to the subsurface. The 3dVAR system performs well for each of the three cruises, suggesting that it is steady for routine usage. | Xianjun Xiao Dongxiao Wang Changxiang Yan Jiang Zhu | 2008 | Progress in Natural Science:Materials International2008，18，5： | 19 |
| 6 | Application of altimetry data assimilation on mesoscale eddies simulation显示文摘Mesoscale eddy plays an important role in the ocean circulation. In order to improve the simulation accuracy of the mesoscale eddies, a three-dimensional variation (3DVAR) data assimilation system called Ocean Variational Analysis System (OVALS) is coupled with a POM model to simulate the mesoscale eddies in the Northwest Pacific Ocean. In this system, the sea surface height anomaly (SSHA) data by satellite altimeters are assimilated and translated into pseudo temperature and salinity (T-S) profile data. Then, these profile data are taken as observation data to be assimilated again and produce the three-dimensional analysis T-S field. According to the characteristics of mesoscale eddy, the most appropriate assimilation parameters are set up and testified in this system. A ten years mesoscale eddies simulation and comparison experiment is made, which includes two schemes: assimilation and non-assimilation. The results of comparison between two schemes and the observation show that the simulation accuracy of the assimilation scheme is much better than that of non-assimilation, which verified that the altimetry data assimilation method can improve the simulation accuracy of the mesoscale dramatically and indicates that it is possible to use this system on the forecast of mesoscale eddies in the future. | GAO Shan WANG Fan LI MingKui CHEN YongLi YAN ChangXiang ZHU Jiang | 2008 | Science China Earth Sciences2008，51，1： | 10 |
| 7 | Regulation of extracellular signal-regulated kinase 1/2 influences hippocampal neuronal survival in a rat model of diabetic cerebral ischemia显示文摘Activation of extracellular signal-regulated kinase 1/2 has been demonstrated in acute brain ischemia. We hypothesized that activated extracellular signal-regulated kinase 1/2 can protect hippocampal neurons from injury in a diabetic model after cerebral ischemia/reperfusion. In this study, transient whole-brain ischemia was induced by four-vessel occlusion in normal and diabetic rats, and extracellular signal-regulated kinase 1/2 inhibitor(U0126) was administered into diabetic rats 30 minutes before ischemia as a pretreatment. Results showed that the number of surviving neurons in the hippocampal CA1 region was reduced, extracellular signal-regulated kinase 1/2 phosphorylation and Ku70 activity were decreased, and pro-apoptotic Bax expression was upregulated after intervention using U0126. These findings demonstrate that inhibition of extracellular signal-regulated kinase 1/2 activity aggravated neuronal loss in the hippocampus in a diabetic rat after cerebral ischemia/reperfusion, further decreased DNA repairing ability and accelerated apoptosis in hippocampal neurons. Extracellular signal-regulated kinase 1/2 activation plays a neuroprotective role in hippocampal neurons in a diabetic rat after cerebral ischemia/ reperfusion. | Yaning Zhao Jianmin Li Qiqun Tang Pan Zhang Liwei Jing Changxiang Chen Shuxing Li | 2014 | Neural Regeneration Research2014，9，7： | 10 |
| 8 | Protective effects of dl-3n-butylphthalide against diffuse brain injury显示文摘Dl-3n-butylphthalide can effectively treat cerebral ischemia;however,the mechanisms underlying the effects of dl-3n-butylphthalide on microcirculation disorders following diffuse brain injury remain unclear.In this study,models of diffuse brain injury were established in Sprague-Dawley rats with the vertical impact method.Dl-3n-butylphthalide at 80 and 160 mg/kg was given via intraperitoneal injection immediately after diffuse brain injury.Ultrastructural changes in the cerebral cortex were observed using electron microscopy.Cerebral blood flow was measured by laser Doppler flowmetry,vascular density was marked by tannic acid-ferric chloride staining,vascular permeability was estimated by the Evans blue method,brain water content was measured using the dry-wet method,and rat behavior was measured by motor function and sensory function tests.At 6,24,48,and 72hours after administration of dl-3n-butylphthalide,reduced cerebral ultrastructure damage,increased vascular density and cerebral blood flow,and improved motor and sensory functions were observed.Our findings demonstrate that dl-3n-butylphthalide may have protective effects against diffuse brain injury by ameliorating microcirculation disorder and reducing blood-brain barrier damage and cerebral edema. | Yaning Zhao Jianmin Li Pan Zhang Changxiang Chen Shuxing Li | 2013 | Neural Regeneration Research2013，8，28： | 7 |
| 9 | Effect of manual acupuncture on bowel motility in normal kunming mouse显示文摘OBJECTIVE:To observe the effects of acupuncture on motility of jejunum and distal colon at different acupoints on normal Kunming mice.METHODS:The jejunal and colorectal motor activity of forty Kunming mice were recorded by the intra-intestinal capsule.The capsules contained with distilled water were placed into the cavities of jejunum and distal colon.The changes of bowel were compared with the background activity recorded before any stimulation.The chosen acupoints were as follows:Zusanli(ST 36) on the lower legs,Tianshu(ST 25) on the mid-lower abdomen.RESULTS:Manual acupuncture(MA) at Zusanli(ST36) significantly promoted the motility of jejunum and distal colon(manifested as increased change rate of average amplitude and increased change rate of mean area under the contractile curve) of normal Kunming mice(P < 0.01).MA atTianshu(ST25) significantly inhibited the motility of jejunum(manifested as decreased change rate of average amplitude,decreased change rate of mean area under the contractile curve,and the reduced frequency) of normal Kunming mice(P < 0.01),while significantly increased the distal colonic motility(manifested as increased amplitude and increased mean area under the contractile curve) of normal Kunming mice(P < 0.01).CONCLUSION:MA at specific acupoints[Zusanli(ST 36),Tianshu(ST 25)]has different effects on the motility of jejunum and distal colon,which might involve the segmental innervations of the related nerve. | Zhao Yuxue Cui Changxiang Qin Qingguang Ben Hui Gao Junhong Yu Xiaochun Zhu Bing | 2015 | Journal of Traditional Chinese Medicine2015，35，2： | 5 |
| 10 | Effect of cDNA fragments in different length derived from Potato Virus Y coat protein gene on the induction of RNA-mediated virus resistance显示文摘We have reported that cDNA derived from entire coat protein (CP) gene of potato virus Y (PVY) could induce resistance to PVY infection in transgenic tobacco plants, and the resistance was further demonstrated to be RNA-mediated rather than coat protein-mediated. In this study, we cloned cDNA fragments of 202 bp, 417 bp, and 603 bp in length derived from the 3′ end of the PVY CP gene, and the cDNA fragments were introduced into tobacco (var. NC89) plants via Agrobacterium-mediated transformation system. The results of resistance assay showed that the CP cDNA fragments of 417 bp and 603 bp could confer resistance of the trans-genic plants to PVY infection, but the fragment of 202 bp in length could not. Molecular analysis revealed that the resistance was RNA-mediated, which is believed to be a result of post-transcriptional gene silencing. The results indicate that the length of cDNA fragments needed for resistance induction was located somewhere between 202 bp and 417 bp from the 3′ end of PVY CP gene. | ZHU Junhua ZHU Xiaoping WEN Fujiang BAI Qingrong ZHU Changxiang SONG Yunzhi | 2004 | Science China(Life Sciences)2004，47，4： | 5 |
| 11 | Behavior Measurement Model Based on Prediction and Control of Trusted Network显示文摘In order to construct the trusted network and realize the trust of network behavior,a new multi-dimensional behavior measurement model based on prediction and control is presented.By using behavior predictive equation,individual similarity function,group similarity function,direct trust assessment function,and generalized predictive control,this model can guarantee the trust of an end user and users in its network.Compared with traditional measurement model,the model considers different characteristics of various networks.The trusted measurement policies established according to different network environments have better adaptability.By constructing trusted group,the threats to trusted group will be reduced greatly.Utilizing trusted group to restrict individuals in network can ensure the fault tolerance of trustworthiness of trusted individuals and group.The simulation shows that this scheme can support behavior measurement more efficiently than traditional ones and the model resists viruses and Trojans more efficiently than older ones. | Gong Bei Zhang Jianbiao Shen Changxiang Zhang Xing | 2012 | China Communications2012，9，5： | 5 |
| 12 | An Ocean Data Assimilation System in the Indian Ocean and West Pacific Ocean显示文摘The development and application of a regional ocean data assimilation system are among the aims of the Global Ocean Data Assimilation Experiment. The ocean data assimilation system in the regions including the Indian and West Pacific oceans is an endeavor motivated by this goal. In this study, we describe the system in detail. Moreover, the reanalysis in the joint area of Asia, the Indian Ocean, and the western Pacific Ocean(hereafter AIPOcean) constructed using multi-year model integration with data assimilation is used to test the performance of this system. The ocean model is an eddy-resolving,hybrid coordinate ocean model. Various types of observations including in-situ temperature and salinity profiles(mechanical bathythermograph, expendable bathythermograph, Array for Real-time Geostrophic Oceanography, Tropical Atmosphere Ocean Array, conductivity–temperature–depth, station data), remotely-sensed sea surface temperature, and altimetry sea level anomalies, are assimilated into the reanalysis via the ensemble optimal interpolation method. An ensemble of model states sampled from a long-term integration is allowed to change with season, rather than remaining stationary. The estimated background error covariance matrix may reasonably reflect the seasonality and anisotropy. We evaluate the performance of AIPOcean during the period 1993–2006 by comparisons with independent observations, and some reanalysis products. We show that AIPOcean reduces the errors of subsurface temperature and salinity, and reproduces mesoscale eddies. In contrast to ECCO and SODA products, AIPOcean captures the interannual variability and linear trend of sea level anomalies very well. AIPOcean also shows a good consistency with tide gauges. | YAN Changxiang ZHU Jiang XIE Jiping | 2015 | Advances in Atmospheric Sciences2015，32，11： | 4 |
| 13 | Recent advances in highly integrated energy conversion and storage system显示文摘The vigorous development in the field of energy conversion and storage devices directly contributes to the full utilization and convenient use of clean energy.However,some drawbacks of independent energy conversion and storage devices,including unstable,insufficient energy output and dependence on external power supply,are difficult to overcome by self-optimization,thus,hindering their further development and direct application.Coincidentally,the combination of above two devices can solve these problems,which conforms to their intrinsic needs for development.At the same time,the pursuit of portability and miniaturization also promotes the development of the power system toward a highly integrated direction.Therefore,we introduce several integration modes of energy conversion and storage systems,with emphasis on all-in-one power system,possessing the highest integration in this review.From the aspect of device configuration,working mechanisms and their performances,the all-inone power systems based on different energy sources(e.g.,mechanical,solar,thermal,and chemical energy)are discussed and analyzed.Finally,the design strategies are summarized and the potential development directions in the future are proposed.This review aims to provide a comprehensive overview of highly integrated energy conversion and storage system,and seeks to point out the opportunities and orientations of future research in this field. | Changxiang Shao Yang Zhao Liangti Qu | 2022 | SusMat2022，2，2： | 3 |
| 14 | Overexpression of phospholipase Dα gene enhances drought and salt tolerance of Populus tomentosa显示文摘The cDNA of AtPLDα (Arabidopsis thaliana Phospholipase Dα) gene was introduced into P. tomentosa (Populus tomentosa) under the control of the Cauliflower mosaic virus 35S promoter. Southern and Northern blot analyses suggested that the AtPLDα gene has been transferred into the P. tomentosa genome. No obvious morphological or developmental difference was observed between the transgenic and wild-type (WT) plants. Drought and salt tolerance and gene expression of seedlings of several transgenic lines and WT plants (control) were studied. The results showed that the rhizogenesis rate and the average root-length of transgenic lines were significantly higher than WT plants after mannitol and NaCl treatment under the same growth conditions. Northern blot analysis indicated that the higher the PLDα expression in the transgenic plants, the more tolerant the transgenic plants are to drought and salt treatment. Meanwhile, another group of these transgenic lines and WT plants (control) were treated with PEG6000 and NaCl separately. The contents of chlorophylls and the activities of some anti-oxidant enzymes (superoxide dismutase, guaiacol peroxidase and catalase) as well as malondialde-hyde and relative electrical conductivity were analyzed. Altogether, our results demonstrated that overexpression of the PLDα gene can enhance the drought and salt tolerance in transgenic P. tomen-tosa plants. | ZHANG TingTing SONG YunZhi LIU YuDong GUO XingQi ZHU ChangXiang WEN FuJiang | 2008 | Chinese Science Bulletin2008，53，23： | 3 |

| 16 | Molecular mechanism of non-alcoholic fatty liver disease induced and aggravated by chronic stress through HSL/ATGL-FFA which promotes fat mobilization显示文摘Objective:To study the effects of social stress(CS)and social stress combined with high-fat diet on fat mobilization as a candidate mechanism for the induction or aggravation of non-alcoholic fatty liver disease(NAFLD).Methods:Thirty-two male Wistar rats(250±10 g)were randomly allocated to a blank control group(BC),a high-fat diet group(HFD),a CS group,and a combined CS and high-fat diet group(CS t HFD).Rats were sacrificed and tissues were collected after 8 weeks.Liver and body mass were measured and used to calculate the liver index.Serum aspartate aminotransferase(AST),alanine aminotransferase(ALT),and free fatty acids(FFAs)were measured.Liver sections were examined microscopically after oil red O and hematoxylin and eosin staining.The relative mRNA expression of acetyl-CoA carboxylase(ACCase),hydroxymethylglutaryl coenzyme A(HMG-CoA)reductase in liver,and hormone-sensitive lipase(HSL),and adipose triglyceride lipase(ATGL)in subcutaneous adipose tissue,were measured by real-time PCR.The liver concentrations of triglyceride,reactive oxygen species,and ACCase were measured by ELISA and HSL activity was determined using turbidimetry.Results:NAFLD developed in the CS,HFD,and CS t HFD groups,with the most severe NAFLD being in the CS t HFD group.Serum AST,ALT,and FFA,liver index,and hepatic triglyceride,FFA,and tumor necrosis factor-a were significantly higher in both the CS and CS t HFD groups.However,food intake and ACCase mRNA expression were lower.The mRNA expression of HSL and ATGL in adipose tissue was much higher,and HSL activity was higher in the CS group than in the BC group,and in the CS t HFD group than in the HFD group.Conclusion:We have successfully established two models of stress-induced NAFLD,suggesting stress can induce and aggravate NAFLD by promoting fat mobilization through upregulation of HSL and ATGL. | Jie Mu Xueqian Wang Qingguo Wang Fafeng Cheng Wenxiang Zhu Changxiang Li Chongyang Ma Changming Zhai Yajun Lian Xin Du | 2019 | Journal of Traditional Chinese Medical Sciences2019，6，4： | 2 |
| 17 | Graphene Oxide Assemblies for Sustainable Clean-Water Harvesting and Green-Electricity Generation显示文摘CONSPECTUS:The urgent problems of water scarcity and the energy crisis have given rise to the development of a range of sustainable technologies with the great advancement of nanotechnologies and advent of attractive nanomaterials.Graphene oxides(GO),a derivative of graphene with an atom-thin thickness and abundant oxygen-containing functional groups(such as−OH,−COOH),are water-soluble and can be assembled into a variety of structures(such as fiber,membrane,and foam)with great potential in environmental and energy-related fields.As a typical precursor of graphene,GO can be easily reduced to graphene by chemical or thermal treatments to demonstrate excellent photothermal properties as well as tunable thermal conduction,which is highly desirable for efficient solar-driven water evaporation.The intrinsic large specific area of GO nanosheets can provide enough sites for ions adsorption and its porous assemblies facilitate the transport of water.In addition,the abundant functional groups allow the spontaneous adsorption of water molecules from the ambient environment and give birth to movable ions(usually protons)under the solvation effect.Once a chemical gradient is formed on the component,a remarkable electricity is generated from the directional transport of protons.Thanks to the excellent chemical properties of GO nanosheets,a wide range of assemblies with 1D aligned fibers,2D layered membranes and 3D porous foam can be easily fabricated by wet-spinning,solution-filtration,and freezingdrying methods.The various GO assemblies are able to exhibit abundant functions with remarkable weaving capability for GO fibers,superior flexibility for GO membranes,and exceptional adsorption capacity for GO foams.In light of all the advantages,GO and its assemblies are remarkably promising in the fields of sustainable development to meet the pressing challenges of water and energy crisis.In this Account,we will discuss the progress of clean-water production and green-electricity generation technologies based on GO assemblies.The fundamental working mechanism,optimization strategies,and promising applications are explored with an emphasis on the materials development.We also discuss the functions of GO assemblies in the water and electricity generation process and present their limitations and possible solutions.Current challenges and promising directions for the development of clean-water production and green-electricity generation are also demonstrated for their realistic implementations.We anticipate that this Account would promote more efforts toward fundamental research on graphene functionalization and encourage a broad exploration on the application of graphene assemblies in clean-water production and electric power generation systems. | Yaxin Huang Chengzhi Wang Changxiang Shao Boyu Wang Nan Chen Haibo Jin Huhu Cheng Liangti Qu | 2021 | Accounts of Materials Research2021，2，2： | 2 |
| 18 | Xiaoqinglong decoction reduces dendritic cell differentiation and regulates the Th1/Th2 balance in a mouse model of allergic asthma显示文摘Background:Xiaoqinglong decoction(XQLD)is a classic Chinese medicinal formula that is widely used to treat allergic asthma.Recently,the use of XQLD to treat allergic asthma has inspired research to determine its mechanism of action.Because dendritic cells(DCs)and the T helper 1(Th1)/Th2 cytokine balance play important roles in allergic asthma,the present work aimed to assess how these immune system components are affected by XQLD.Methods:Thirty-six female BALB/C mice were randomly divided into three groups:an ovalbumin-based allergic asthma model group,a XQLD treatment group,and a control group.Histology was performed with haematoxylin and eosin staining and immunohistochemical staining.Bronchoalveolar lavage fluid and blood were collected from the animals and used to analyze the composition of inflammatory cells and expression levels of the cytokines interleukin(IL)-5 and IL-13.The thymic stromal lymphopoietin(TSLP)protein expression was assessed by western blot analysis,and the Gata3 and Tbx21 mRNA levels were assessed by polymerase chain reaction.Results:Compared with the OVA group,the levels of TSLP expression,IL-5,IL-13,and immunoglobulin E in the XQLD group were lower(all P<.01).The level of IL-4-expressing cells(Th2 cells)was lower(P=.0013),and the percentage of IFN-g-expressing cells(Th1 cells)was higher in the XQLD group compared with those in the OVA group(P=.0065).In addition,XQLD increased the expression of Tbx21 mRNA and decreased the expression of Gata3 mRNA in the lungs compared with the OVA group(both P<.01).Conclusion:These findings suggest that XQLD may ameliorate the course of allergic asthma by regulating the Gata3/Tbx21 balance and inhibiting TSLP expression,changes which are indicative of an altered Th1/Th2 balance.Thus,the clinical effectiveness of XQLD in treating allergic asthma may be due to its regulation of Th1/Th2 balance. | Juntang Yan Nan Deng Qingguo Wang Xin Du Changxiang Li Ting Xie Yanxia Liu Min Liu | 2020 | Journal of Traditional Chinese Medical Sciences2020，7，2： | 2 |
| 19 | Security Architecture of Trusted Virtual Machine Monitor for Trusted Computing显示文摘With analysis of limitations Trusted Computing Group (TCG) has encountered, we argued that virtual machine monitor (VMM) is the appropriate architecture for implementing TCG specification. Putting together the VMM architecture, TCG hard- ware and application-oriented “thin” virtual machine (VM), Trusted VMM-based security architecture is present in this paper with the character of reduced and distributed trusted computing base (TCB). It provides isolation and integrity guarantees based on which general security requirements can be satisfied. | HUANG Qiang SHEN Changxiang FANG Yanxiang | 2007 | Wuhan University Journal of Natural Sciences2007，12，1： | 2 |
| 20 | Formal Compatibility Model for Trusted Computing Applications显示文摘The Chinese specification for trusted computing, which has similar functions with those defined by the Trusted Computing Group (TCG), has adopted a different cryptography scheme. Applications designed for the TCG specifications cannot directly function on platforms complying with Chinese specifications because the two cryptography schemes are not compatible with each other. In order to transplant those applications with little to no modification, the paper presents a formal compatibility model based on Zaremski and Wing’s type system. Our model is concerned not only on the syntactic compatibility for data type, but also on the semantic compatibility for cryptographic attributes according to the feature of trusted computing. A compatibility algorithm is proposed based on the model to generate adapters for trusted computing applications. | ZHU Lu YU Sheng ZHANG Xing SHEN Changxiang | 2009 | Wuhan University Journal of Natural Sciences2009，14，5： | 2 |
