| 1 | Influence of soil type and genotype on Cd bioavailability and uptake by rice and implications for food safety显示文摘Cadmium(Cd) entering the human body via the food chain is of increasing concern.This study investigates the effects of soil type and genotype on variations in the Cd concentrations of different organs of nine rice plants grown on two types of soils with two Cd levels.Cd concentrations in nine rice cultivars varied significantly with genotype and soil type(P < 0.01).The Cd concentration was higher in red paddy soil(RP) than in yellow clayey paddy soil(YP).The average Cd concentrations of different organs in three rice types were indica > hybrid > japonica for the Cd treatments and controls.The polished grain concentration in YP and RP soils had a range of 0.055-0.23 mg/kg and 0.13-0.36 mg/kg in the Cd treatment,respectively.Two rice cultivars in YP soil and five rice cultivars in RP soil exceeded the concentration limits in the Chinese Food Hygiene Standard(0.2 mg/kg).The Cd concentrations in roots,stems,and leaves were all significantly and positively correlated to that in polished grain in a single test.The Cd concentrations in polished grain were positively and significantly(P < 0.01) correlated with the calculated transfer factors of stem to grain and leaf to grain Cd transfer.The results indicated that the variations of Cd concentration in grain were related to Cd uptake and the remobilization of Cd from stem and leaf to grain.Also,the cultivars with a strong tendency for Cd-accumulation should be avoided in paddy soil with low soil pH and low organic matter content to reduce the risks to human health from high Cd levels in rice. | Xinxin Ye Yibing Ma Bo Sun | 2012 | Journal of Environmental Sciences2012，24，9： | 34 |
| 2 | EABDS: Attribute-Based Secure Data Sharing with Efficient Revocation in Cloud Computing显示文摘Ciphertext-policy attribute-based encryption(CP-ABE) is becoming a promising solution to guarantee data security in cloud computing. In this paper,we present an attribute-based secure data sharing scheme with Efficient revocation(EABDS) in cloud computing.Our scheme first encrypts data with Data encryption key(DEK) using symmetric encryption and then encrypts DEK based on CP-ABE, which guarantees the data confidentiality and achieves fine-grained access control. In order to solve the key escrow problem in current attribute based data sharing schemes, our scheme adopts additively homomorphic encryption to generate attribute secret keys of users by attribute authority in cooperation with key server, which prevents attribute authority from accessing the data by generating attribute secret keys alone.Our scheme presents an immediate attribute revocation method that achieves both forward and backward security.The computation overhead of user is also reduced by delegating most of the decryption operations to the key server.The security and performance analysis results show that our scheme is more secure and efficient. | HUANG Qinlong MA Zhaofeng YANG Yixian FU Jingyi NIU Xinxin | 2015 | Chinese Journal of Electronics2015，24，4： | 8 |
| 3 | Archaeal community structure along a gradient of petroleum contamination in saline-alkali soil显示文摘The response of archaeal communities to petroleum contamination in saline-alkali soil was characterized by analyses of three soil samples with different total petroleum hydrocarbon concentrations.Through the construction and screening of 16S rRNA gene clone libraries based on DNA extracts from these soils,nine distinct phylogenetic groups were identified.Statistical analyses showed that the distribution of archaeal community structures differ significantly along the gradient of petroleum contamination in these three saline- alkali soils.Five phylogenetic groups were dominant in the control soil,two of which were also abundant in the lightly contaminated soil.Four phylogenetic groups were dominant in heavily contaminated soil,one of which was also abundant in the lightly contaminated soil.The halophilic genus of Haloferax and the haloalkaliphilic genus of Natronomonas were more abundant in heavily contaminated soil.These results suggested that the genera of Haloferax and Natronomonas may have a role in the natural attenuation of petroleum- contaminated saline-alkali soil. | Xinxin Wang Zhen Han Zhihui Bai Jingchun Tang Anzhou Ma Jizheng He Guoqiang Zhuang | 2011 | Journal of Environmental Sciences2011，23，11： | 8 |
| 4 | Compressive Sensing-Based Audio Semi-fragile Zero-Watermarking Algorithm显示文摘A novel compressive sensing-based audio semi-fragile zero-watermarking algorithm is proposed in this paper. This algorithm transforms the original audio signal into the wavelet domain and applies compressive sensing theory to the approximation wavelet coefficients.The zero-watermarking is constructed according to the positive and negative properties of elements in the measurement vector. The experimental results show that the proposed algorithm is robust against common audio signal processing and fragile to malicious tampering. Compared with the existing algorithms, the proposed algorithm improves malicious tampering detection accuracy in common audio signal processing environments. | TANG Xin MA Zhaofeng NIU Xinxin YANG Yixian | 2015 | Chinese Journal of Electronics2015，24，3： | 5 |
| 5 | Superior anti-corrosion and self-healing bi-functional polymer composite coatings with polydopamine modified mesoporous silica/graphene oxide显示文摘In this article,graphene oxide(GO)and benzotriazole-loaded mesoporous silica nanoparticles(BTA/MSNs)are combined on micro scale through the in situ polymerization of polydopamine(PDA),preparing a selfhealing bi-functional GO(fGO)used as nano-fillers for anti-corrosion enhancement of waterborne epoxy(WEP)coatings.Scanning electronic microscopy(SEM)images show that the BTA/MSNs are uniformly distributed on the surface of high aspect ratio GO nanosheets to endow GO nanocontainer characteristics.UV-vis profiles demonstrate that fGO has p H-controlled release function.Modulus at lowest frequency is generally used for comparing the corrosion resistance of organic coatings.Modulus at lowest frequency(1.42×10^(5)Ωcm^(2))after 30 days immersion in 3.5 wt.%Na Cl solution revealed 2 orders of magnitude higher that of blank WEP(1.17×10^(7)Ωcm^(2)).With artificial cracks on its coatings,fGO/WEP had no obvious rust compared with blank WEP after 240 h of immersion.We anticipate that self-healing and physical barrier bi-functional nanocontainers improve the traditional anticorrosion coating efficiency with better,longer-lasting performance for shipping,oil drilling or bridge maintenance. | Yanqi Ma Haowei Huang Hongda Zhou Michael Graham James Smith Xinxin Sheng Ying Chen Li Zhang Xinya Zhang Elena Shchukina Dmitry Shchukin | 2021 | Journal of Materials Science & Technology2021，，36： | 4 |
| 6 | Hybrid nano-scale Au with ITO structure for a high-performance near-infrared silicon-based photodetector with ultralow dark current显示文摘An internal photoemission-based silicon photodetector detects light below the silicon bandgap at room temperature and can exhibit spectrally broad behavior,making it potentially suited to meet the need for a near-infrared pure Si photodetector.In this work,the implementation of a thin Au insertion layer into an ITO/n-Si Schottky photodetector can profoundly affect the barrier height and significantly improve the device performance.By fabricating a nanoscale thin Au layer and an ITO electrode on a silicon substrate,we achieve a well-behaved ITO/Au/n-Si Schottky diode with a record dark current density of 3.7×10^(−7) A/cm^(2) at−1 V and a high rectification ratio of 1.5×10^(8) at±1 V.Furthermore,the responsivity has been obviously improved without sacrificing the dark current performance of the device by decreasing the Au thickness.Such a silicon-based photodetector with an enhanced performance could be a promising strategy for the realization of a monolithic integrated pure silicon photodetector in optical communication. | Xinxin Li Zhen Deng Jun Li Yangfeng Li Linbao Guo Yang Jiang Ziguang Ma Lu Wang Chunhua Du Ying Wang Qingbo Meng Haiqiang Jia Wenxin Wang Wuming Liu Hong Chen | 2020 | Photonics Research2020，8，11： | 4 |
| 7 | An insight into failure mechanism of NASICON-structured Na3V2(PO4)3 in hybrid aqueous rechargeable battery显示文摘NASICON (Na-super-ionic-conductors)-structured materials have attracted extensive research interest due to their great application potential in secondary batteries. However, the mechanism of capacity fading for NASICON-structured electrode materials has been rarely studied. In this paper, we synthesized the NASICON-structured Na3V2(PO4)3/C composite by simple sol-gel and high-temperature solid-phase method and investigated its electrochemical performance in Na-Zn hybrid aqueous rechargeable batteries. After characterizing the structure, morphology and composition variations as well as the interfacial resistance changes of Na3V2(PO4)3/C cathode during cycling, we propose a mechanical and interfacial degradation mechanism for capacity fading of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. This work will shed light on enhancing the mechanical and in terfacial stability of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. | Xinxin Zhang Jun Ma Pu Hu Bingbing Chen Chenglong Lu Xinhong Zhou Pengxian Han Lihua Chen Guanglei Cui | 2019 | Journal of Energy Chemistry2019，28，5： | 3 |
| 8 | Attribute Based DRM Scheme with Dynamic Usage Control in Cloud Computing显示文摘In order to achieve fine-grained access control in cloud computing,existing digital rights management(DRM) schemes adopt attribute-based encryption as the main encryption primitive.However,these schemes suffer from inefficiency and cannot support dynamic updating of usage rights stored in the cloud.In this paper,we propose a novel DRM scheme with secure key management and dynamic usage control in cloud computing.We present a secure key management mechanism based on attribute-based encryption and proxy re-encryption.Only the users whose attributes satisfy the access policy of the encrypted content and who have effective usage rights can be able to recover the content encryption key and further decrypt the content.The attribute based mechanism allows the content provider to selectively provide fine-grained access control of contents among a set of users,and also enables the license server to implement immediate attribute and user revocation.Moreover,our scheme supports privacy-preserving dynamic usage control based on additive homomorphic encryption,which allows the license server in the cloud to update the users' usage rights dynamically without disclosing the plaintext.Extensive analytical results indicate that our proposed scheme is secure and efficient. | HUANG Qinlong | 2014 | China Communications2014，11，4： | 3 |
| 9 | A Video Watermarking DRM Method Based on H.264 Compressed Domain with Low Bit-Rate Increasement显示文摘It gets more and more important for video copyright protection,it is necessary to provide efficient H.264 compression domain watermarking for video Digital rights management(DRM).A new watermarking method based on H.264 compressed domain is proposed for video DRM,in which the embedding and extracting procedure are performed using the syntactic elements of the compressed bit stream.In this way,complete decoding is unnecessary in both embedding and extracting processes.Based on the analysis of the time and space,some appropriate sub-blocks are selected for embedding watermarks,increasing watermark robustness while reducing the declination of the visual quality.In order to avoid bit-rate increasing and strengthen the security of the proposed video watermarking scheme,only a set of nonzero coefficients quantized in different parts of macroblocks is chosen for inserting watermark.The experiment results show the proposed scheme can achieve excellent robustness against some common attacks,the proposed scheme is secure and efficient for video content DRM protection. | MA Zhaofeng HUANG Jianqing JIANG Ming NIU Xinxin | 2016 | Chinese Journal of Electronics2016，25，4： | 3 |
| 10 | Secure Data Sharing and Retrieval Using Attribute-Based Encryption in Cloud-Based OSNs显示文摘The Online social networks(OSNs) offer attractive means for social interactions and data sharing,but also raise a number of security and privacy issues. Since the OSNs service provider is always semi-trusted, current solutions propose to encrypt data before sharing. However,data encryption causes a lot of inconveniences and large overheads for data dissemination and data retrieval. In this paper, we propose a secure data sharing and retrieval scheme in cloud-based OSNs. Based on ciphertext-policy attribute-based encryption, our scheme achieves multiparty access control, which allows data owners to outsource encrypted data to the OSNs service provider for sharing,and enables data disseminators to disseminate the data owners' data by customizing new access policy. Our scheme also provides searchable encryption scheme to support fast searches in massive amount of encrypted data from both data owners and data disseminators. Further, our scheme preserves the privacy of data owners and data retrievers during the data sharing and retrieval processes. In addition, the computation overhead of data retrievers is reduced by delegating most of the decryption operations to the OSNs service provider. The security and performance analysis results indicate that our scheme is secure and privacy-preserving. | HUANG Qinlong MA Zhaofeng YANG Yixian FU Jingyi NIU Xinxin | 2014 | Chinese Journal of Electronics2014，23，3： | 3 |
| 11 | Preparation and Properties of Smart Thermal Control and Radiation Protection Materials for Multi-functional Structure of Small Spacecraft显示文摘Considering the unique properties of small spacecraft,such as light weight,low power-consumption and high heat flux density,a new kind of lightweight boron carbide(B 4 C) radiation-protection coating material was proposed.New techniques for preparing LSMO thermal control coating and B 4 C radiation-protection coating were developed.The sample piece of multi-functional structure was manufactured by using the proposed materials,and a series of performance tests,such as thermal control and radiation-protection behaviors were evaluated.Test results show that:the emissivity of the multi-functional structure varies from 0.42 to 0.86 at 240 K to 353 K and the phase transition temperature is about 260 K.The electron radiation-protection ability of the multi-functional structure is 3.3 times better than that of Al material.The performance index of this multi-functional structure can meet the requirements for space application in on-board electronic equipment. | shijie Zhang Xibin Cao Yingqiang Luan Xinxin Ma Xiaohui Lin Xianren Kong | 2011 | Journal of Materials Science & Technology2011，27，10： | 3 |
| 12 | Properties of Aluminum Oxide (AlO_x) Barrier Coatings Deposited on Poly(Ethylene Terephthalate)(PET)Substrates by Reactive Magnetron Sputtering显示文摘The aluminum oxide(AlOx)coatings were deposited on poly(ethylene terephthalate)(PET)surface by reactive magnetron sputtering for improving its barrier property.With O2 flux increasing,three modes including metallic mode,transition mode and oxide mode exist in sputtering.The properties of the aluminum oxide(AlOx)coatings prepared at different modes were discussed.Also,the influences of oxygen flux on the stoichiometry,structure,gas permeation of the coatings were investigated.The chemical composition of AlOx films fabricated in transition mode is different as oxygen flux varies slightly,and the gas barrier property is better as the stoichiometry is closer to 1.5 with oxygen flux increasing.The coating uniformity,roughness and particle size depend remarkably upon oxygen flux.The coatings deposited at oxide mode have a good barrier performance to oxygen and water,and the permeability to oxygen decreases by sixty times and water vapor ten times compared with uncoated | Liu Zhuang Ma Xinxin Sun Zhihui Xu Fangjun | 2012 | 稀有金属材料与工程2012，41，S1： | 3 |
| 13 | Research on the Relationship between Grain Composition and Repose Angle of Coal Gangue in Dongkuang Mine, Heshan City, Guangxi, China显示文摘Heshan, a city in Southwest China, has been built over an old coal mining area. Due to low level of reclamation, coal gangue had been stacked in large heaps and caused geological environmental problems. To facilitate designing management project of coal gangue, we made an investigation of the largest coal gangue heap in Dongkuang Mine of Heshan. Firstly, the grain composition of coal gangue was estimated through the sieving method, then the representative grading curve was drawn through the statistics method of coarse grain content, and lastly the relationship between the repose angle and grain grading was studied by piling up coal gangue with different mix proportion. The result indicates that there is a wider range of grain size in the upper part of coal gangue heap, and the representative grain grading is well graded and easy to be compacted as filling materials. Besides, the wavy relationship curve of repose angle and coarse grain content shows that the content of 70% is the inflection point of ascent stage and 85% the inflection point of descent stage of the repose angle. What's more, the repose angle corresponding to the representative grading of coal gangue is approximately 38.4° and this has guiding significance for management project of coal gangue. | Zhaohui Tang Xinxin Dong Yue Yang Li Ma | 2014 | Journal of Earth Science2014，25，2： | 3 |

| 15 | EasySVM: A visual analysis approach for open-box support vector machines显示文摘Support vector machines(SVMs) are supervised learning models traditionally employed for classification and regression analysis. In classification analysis, a set of training data is chosen, and each instance in the training data is assigned a categorical class. An SVM then constructs a model based on a separating plane that maximizes the margin between different classes. Despite being one of the most popular classification models because of its strong performance empirically, understanding the knowledge captured in an SVM remains difficult. SVMs are typically applied in a black-box manner where the details of parameter tuning, training, and even the final constructed model are hidden from the users. This is natural since these details are often complex and difficult to understand without proper visualization tools. However, such an approach often brings about various problems including trial-and-error tuning and suspicious users who are forced to trust these models blindly.The contribution of this paper is a visual analysis approach for building SVMs in an open-box manner.Our goal is to improve an analyst's understanding of the SVM modeling process through a suite of visualization techniques that allow users to have full interactive visual control over the entire SVM training process.Our visual exploration tools have been developed to enable intuitive parameter tuning, training datamanipulation, and rule extraction as part of the SVM training process. To demonstrate the efficacy of our approach, we conduct a case study using a real-world robot control dataset. | Yuxin Ma Wei Chen Xiaohong Ma Jiayi Xu Xinxin Huang Ross Maciejewski Anthony K.H.Tung | 2017 | Computational Visual Media2017，3，2： | 2 |
| 16 | A Novel Image Digital Rights Management Scheme with High-Level Security,Usage Control and Traceability显示文摘Current methods of image protection based on chaos encryption can only provide security in Human visual system(HVS) level, however they can not provide usage control when the image is opened, printed or exported. To solve this problem, we proposed a novel image digital rights management scheme for Confidential image data security based on encryption and watermark(CIDSEW) with high-level security, usage control and traceability, in which we employed full content image encryption for confidentiality of the image to be protected, and we firstly proposed strict and detailed Usage control(UC) scheme for Confidential image data(CIData) usage password-based authentication, opening times, printing and exporting control. And when the CIData need to delivery or export to other users or domain, we proposed the secure export and misused tracing and detect approach, in which before the ciphered CIData is exported, we decrypted the CIData in a plain mode, and simultaneously we embedded user-identity-related and hardware-related information as robust watermark for traceability and responsibility confirmation. Finally, we evaluated the proposed CIDSEW by groups of variant size image data for security and efficiency,a large amount of groups of experiments manifest the proposed CIDSEW is secure, efficient, pervasive and robust for confident image data protection, usage control and misuse tracing. | MA Zhaofeng HUANG Jianqing JIANG Ming NIU Xinxin | 2016 | Chinese Journal of Electronics2016，25，3： | 2 |
| 17 | Improving Security and Sharing in Online Social Efficiency for Encrypted Data Networks显示文摘Despite that existing data sharing systems in online social networks(OSNs)propose to encrypt data before sharing,the multiparty access control of encrypted data has become a challenging issue.In this paper,we propose a secure data sharing scheme in OSNs based on ciphertext-policy attributebased proxy re-encryption and secret sharing.In order to protect users' sensitive data,our scheme allows users to customize access policies of their data and then outsource encrypted data to the OSNs service provider.Our scheme presents a multiparty access control model,which enables the disseminator to update the access policy of ciphertext if their attributes satisfy the existing access policy.Further,we present a partial decryption construction in which the computation overhead of user is largely reduced by delegating most of the decryption operations to the OSNs service provider.We also provide checkability on the results returned from the OSNs service provider to guarantee the correctness of partial decrypted ciphertext.Moreover,our scheme presents an efficient attribute revocation method that achieves both forward and backward secrecy.The security and performance analysis results indicate that the proposed scheme is secure and efficient in OSNs. | HUANG Qinlong | 2014 | China Communications2014，11，3： | 2 |
| 18 | Tuning crystal structure and redox potential of NASICON-type cathodes for sodium-ion batteries显示文摘Sodium superionic conductor(NASICON)-type compounds have been regarded as promising cathodes for sodium-ion batteries(SIBs)due to their favorable ionic conductivity and robust structural stability.However,their high cost and relatively low energy density restrict their further practical application,which can be tailored by widening the operating voltages with earth-abundant elements such as Mn.Here,we propose a rational strategy of infusing Mn element in NASICON frameworks with sufficiently mobile sodium ions that enhances the redox voltage and ionic migration activity.The optimized structure of Na3.5Mn0.5V1.5(PO4)3/C is achieved and investigated systematically to be a durable cathode(76.6%capacity retention over 5,000 cycles at 20 C)for SIBs,which exhibits high reversible capacity(113.1 mAh·g^−1 at 0.5 C)with relatively low volume change(7.6%).Importantly,its high-areal-loading and temperature-resistant sodium ion storage properties are evaluated,and the full-cell configuration is demonstrated.This work indicates that this Na3.5Mn0.5V1.5(PO4)3/C composite could be a promising cathode candidate for SIBs. | Xuemei Ma Xinxin Cao Yifan Zhou Shan Guo Xiaodong Shi Guozhao Fang Anqiang Pan Bingan Lu Jiang Zhou Shuquan Liang | 2020 | Nano Research2020，13，12： | 2 |

| 20 | Robust Audio Watermarking Algorithm Based on Empirical Mode Decomposition显示文摘A novel robust audio watermarking algorithm based on empirical mode decomposition is proposed.The intrinsic feature of the final residual decomposed from the audio frame is selected to embed watermark and the algorithm works by shifting each element of the final residual to make its sum greater or less than 0. The experimental results show that the proposed algorithm does not change the property of the final residual after embedding watermark and the watermark is robust against various kinds of attacks. Compared with existing classic algorithms based on Empirical mode decomposition(EMD), the proposed algorithm largely improves both the robustness and imperceptibility of watermarking. | TANG Xin MA Zhaofeng NIU Xinxin YANG Yixian | 2016 | Chinese Journal of Electronics2016，25，6： | 2 |
