| 1 | Arsenic hyperaccumulator Pteris Vittata L. and its arsenic accumulation显示文摘An arsenic hyperaccumulator Pteris vittata L. (Chinese brake) was first discovered in China by means of field survey and greenhouse cultivation. Field survey showed that Chinese brake had large accumulating capacity to arsenic; the orders of arsenic content in different parts of the fern were as follows: leaves>leafstalks>roots, which is totally different from that of ordinary plants; bioaccumulation coefficients of the above ground parts of the fern decreased as a power function of soil arsenic contents. In the control of pot trials with normal unpolluted soil containing 9mg/kg of arsenic, the bioaccumulation coefficients of the above ground parts and rhizoids of Chinese brake were as high as 71 and 80 respectively. Greenhouse cultivation in the contaminated soil from mining areas has shown that more than 1 times greater arsenic can be accumulated in the leaves of the fern than that of field samples with the largest content of 5070 mg/kg As on a dry matter basis. During greenhouse cultivation, arsenic | Tongbin Chen Chaoyang Wei Zechun Huang Qifei Huang Quanguo Lu Zilian Fan | 2002 | Chinese Science Bulletin2002，47，11： | 108 |
| 2 | Characterizing spatial distribution and sources of heavy metals in the soils from mining-smelting activities in Shuikoushan,Hunan Province,China显示文摘The spatial variation of heavy metals in the soils in Shuikoushan mining-smelting area,Hunan Province,China,was investigated using multivariate and geo-statistic analysis.A total of 106 composite soil samples were collected in an area of about 100 km2. Concentrations of total As,Cd,Pb,Zn,Cu and Cr were measured using inductively coupled plasma mass spectrometry(ICP-MS) . Arsenic and Pb were found to have a common source,indicating the same sources and spreading processes,such as aerosols and airborne particulates from smelting chimneys.Airborne sources from smelting chimneys contributed greatly to Cd in the area,which demonstrated the same dispersion pattern as As and Pb.However,two hot spots of Cd around smelters were possibly enlarged by wastewaters,demonstrating another important source of Cd in Shuikouhsan.Geo-statistic interpolated mapping demonstrated that hotspots of Zn were only found proximal to the large smelters,suggesting that Zn primarily came from the chimneys of larger smelters. The major Cu hot-spots appeared closely to the tailing dam,indicating that weathering and leaching of tailings were the major sources of Cu contamination in Shuikoushan.Our findings indicated that airborne volatile particles and aerosols contributed the most to As,Cd,Pb,Zn and Cu contamination,while Cd and Cu may also derive from the discharge of wastewater from smelters and the leaching of tailings,respectively. | WEI Chaoyang WANG Cheng YANG Linsheng | 2009 | Journal of Environmental Sciences2009，21，9： | 48 |
| 3 | Effect of phosphorus on arsenic accumulation in As-hyperaccumulator Pteris vittata L. and its implication显示文摘Pot experiment was conducted to understand the effect of phosphorus on arsenic accumulation in As-hyperaccumulator Chinese brake (Pteris vittata L.). It is shown that arsenic concentrations in the fronds and rhizoids, the arsenic bioaccumulation factor, and the total arsenic in the fronds were not influenced significantly under low levels of phosphorus (≤400 mg/kg) and increased sharply under high levels of phosphorus (>400 mg/ kg). The discovery implies that the efficiency of arsenic removal in phytoremedia-tion using the hyperaccumulating plant can be greatly elevated by the phosphorus addition at high rates. The interaction between the accumulation of phosphorus and that of arsenic in plant was stimulated mutually. The result represents that Chinese brake is a good material for plant physiologist to conduct comparative and mechanism studies on the uptake behaviors of phosphorus and arsenic, and phosphorus is also a potential accelerator for phytoremediation of arsenic-contaminated soils. | Tongbin Chen Zhilian Fan Mei Lei Zechun Huang Chaoyang Wei | 2002 | Chinese Science Bulletin2002，47，22： | 35 |
| 4 | Hepatitis C Virus Infection Downregulates the Ligands of the Activating Receptor NKG2D显示文摘Natural killer (NK) cells are a major component of the host innate immune defense against various pathogens. Several viruses, including hepatitis C virus (HCV), have developed strategies to evade the NK-cell response. In our study, we found HCV infection could trigger DNA damage response by both ataxia telangiectasia mutated (ATM) and ATM- and Rad3-related (ATR) pathways. Recent reports had revealed that NKG2D ligands (NK cell-activating ligands) were upregulated when a major DNA damage checkpoint pathway was activated. However, here we found that DNA damage response was activated but NKG2D ligands were downregulated upon HCV infection. Further studies showed that the protease NS3/4A of HCV which had been shown relation with immune invasion contributed to the reduced expression of NKG2D ligands. These findings provide a novel insight into the mechanisms evolved by HCV to escape from the NK cell response. | Chaoyang Wen Xiang He Hongfang Ma Ningbo Hou Congwen Wei Ting Song Yanhong Zhang Liping Sun Qingjun Ma Hui Zhong | 2008 | Cellular & Molecular Immunology2008，5，6： | 6 |
| 5 | A theoretical framework for quantum image representation and data loading scheme显示文摘Two fundamental problems exist in the use of quantum computation to process an image or signal.The first one is how to represent giant data,such as image data,using quantum state without losing information.The second one is how to load a colossal volume of data into the quantum registers of a quantum CPU from classical electronic memory.Researches on these two questions are rarely reported.Here an entangled state is used to represent an image(or vector)for which two entangled registers are used to store a vector component and its classical address.Using the representation,n1+n2+8 qubits are used to store the whole information of the gray image that has a 2n1×2n2 size at a superposition of states,a feat is not possible with a classic computer.The way of designing a unitary operation to load data,such as a vector(or image),into the quantum registers of a quantum CPU from electronic memory is defined herein as a quantum loading scheme(QLS).In this paper,the QLS with time complexity O(log2N)is presented where N denotes the number of vector components,a solution that would break through the efciency bottleneck of loading data.QLS would enable a quantum CPU to be compatible with electronic memory and make possible quantum image compression and quantum signal processing that has classical input and output. | HU BenQiong HUANG XuDong ZHOU RiGui WEI YanYu WAN Qun PANG ChaoYang | 2014 | Science China(Information Sciences)2014，57，3： | 5 |
| 6 | Cross-Scale Synthesis of Organic High-k Semiconductors Based on Spiro-Gridized Nanopolymers显示文摘High dielectric constants in organic semiconductors have been identified as a central challenge for the improvement in not only piexoelectric,preolecric,and freeltric efcts but also photoclecric conversion eficiency in OPVs,carrier mobility in OFETS,and charge density in charge-trapping memories.Herein,we report an ultralong persistence length(≈41 nm)efet of spiro-fused organic nanopolymers on dielectric properties,together with excitonic and charge carrier behaviors.The state-of-the-art nanopolymers,namely,nanopolyspirogrids(NPSGs),are synthesized via the simple crossscale Friedel-Crafts polygridlization of AjB-type nanomonomers.The high dielectric constant(k=8.43)of NPSG is firstly achieved by locking spiro-polygridization efect that results in the enhancement of dipole polarization.When doping into a polystyrene-based dielectric layer,such a high-k feature of NPSG increases the feld-ffct carrier mobility from 0.20 to 0.90cm^(2)Vl s'in pentacene OFET devices.Meanwhile,amorphous NPSG film exhibits an ultralow energy disorder(<50 meV)for an exellent zero-field hole mobility of 3.94×10^(-1)cm^(2)V^(-1)s^(-1).surpassing most of the amorphousπconjugated polymers Onganic nanopolymers with high dielectric constants open a new way to break through the bottleneck of eficiency and multifunctionality in the blueprint of the fourth generation semiconductors. | Dongqing Lin Wenhua Zhang Hang Yin Haixia Hu Yang Li He Zhang Le Wang Xinmiao Xie Hongkai Hu Yongxia Yan Haifeng Ling Jin'an Liu Yue Qian Lei Tang Yongxia Wang Chaoyang Dong Linghai Xie Hao Zhang Shasha Wang Ying Wei Xuefeng Guo Dan Lu Wei Huang | 2022 | Research2022，，2： | 3 |
| 7 | Development of high-power laser coatings显示文摘Laser resistance and stress-free mirrors,windows,polarizers,and beam splitters up to 400 mm×400 mm are required for the construction of the series SG facilities.In order to improve the coating quality,a program has been in place for the last ten years.For the small-aperture pick-off mirror,the laser-induced damage threshold(LIDT)is above 60 J/cm2(1064 nm,3 ns),and the reflected wavefront is less thanλ/4(λ=633 nm).The Brewster-angle polarizing beam splitter(Φ50×10 mm)shows the best LIDT result,up to 29.8 J cm 2(1064 nm,10 ns)for a p-polarized wave in the 2012damage competition of the XLIV Annual Boulder Damage Symposium.For the larger-aperture mirror and polarizer,the LIDT is above 23 J cm 2(1064 nm,3 ns)and 14 J cm 2(1064 nm,3 ns),respectively.The reflected wavefront is less thanλ/3(λ=633 nm)at the used angle. | Hongji Qi Meipin Zhu Ming Fang Shuying Shao Chaoyang Wei Kui Yi Jianda Shao | 2013 | High Power Laser Science and Engineering2013，1，1： | 2 |

| 18 | Moment-independence global sensitivity analysis for the system with fuzzy failure state and its Kriging method显示文摘For the system with the fuzzy failure state, the effects of the input random variables and the fuzzy failure state on the fuzzy probability of failure for the structural system are studied, and the moment-independence global sensitivity analysis(GSA) model is proposed to quantitatively measure these effects. According to the fuzzy random theory, the fuzzy failure state is transformed into an equivalent new random variable for the system, and the complementary function of the membership function of the fuzzy failure state is defined as the cumulative distribution function(CDF) of the new random variable. After introducing the new random variable, the equivalent performance function of the original problem is built. The difference between the unconditional fuzzy probability of failure and conditional fuzzy probability of failure is defined as the moment-independent GSA index. In order to solve the proposed GSA index efficiently, the Kriging-based algorithm is developed to estimate the defined moment-independence GSA index. Two engineering examples are employed to verify the feasibility and rationality of the presented GSA model, and the advantages of the developed Kriging method are also illustrated. | LI Guijie XIE Chaoyang WEI Fayuan WANG Fengjun | 2018 | Journal of Systems Engineering and Electronics2018，29，3： | 1 |

| 20 | Transceiver Optimization for Multi-Antenna Device-to-Device Communications显示文摘It has been shown that the deployment of device-to-device(D2D) communication in cellular systems can provide better support for local services. However, improper design of the hybrid system may cause severe interference between cellular and D2D links. In this paper, we consider transceiver design for the system employing multiple antennas to mitigate the interference. The precoder and decoder matrices are optimized in terms of sum mean squared error(MSE) and capacity, respectively. For the MSE minimization problem, we present an alternative transceiver optimization algorithm. While for the non-convex capacity maximization problem, we decompose the primal problem into a sequence of standard convex quadratic programs for efficient optimization. The evaluation of our proposed algorithms for performance enhancement of the entire D2D integrated cellular system is carried out through simulations. | Daohua Zhu Yajuan Guo Lei Wei Chaoyang Zhu Biyao Huang Wei Xu Chunming Zhao | 2016 | China Communications2016，13，5： | 1 |
