| 1 | Research on Link Quality Estimation Mechanism for Wireless Sensor Networks Based on Support Vector Machine显示文摘In the application of Wireless sensor networks(WSNs),effective estimation for link quality is a basic issue in guarantying reliable data transmission and upper network protocol performance.A link quality estimation mechanism is proposed,which is based on Support vector machine(SVM) with multi-class classification.Under the analysis of the wireless link characteristics,two physical parameters of communication,Receive signal strength indicator(RSSI) and Link quality indicator(LQI),are chosen as estimation parameters.The link quality is divided into five levels according to Packet reception rate(PRR).A link quality estimation model based on SVM with decision tree is established.The model is built on kernel functions of radial basis and polynomial respectively,in which RSSI,LQI are the input parameters.The experimental results show that the model is reasonable.Compared with the recent published link quality estimation models,our model can estimate the current link quality accurately with a relative small number of probe packets,so that it costs less energy consumption than the one caused by sending a large number of probe packets.So this model which is high efficiency and energy saving can prolong the network life. | SHU Jian LIU Song LIU Linlan ZHAN Liqin HU Gang | 2017 | Chinese Journal of Electronics2017，26，2： | 12 |

In this paper, a new class of quantum MDS code is constructed, which extends the result of [Theorems 3.14–3.15, Kai, X., Zhu, S., and Li,P., IEEE Trans. on Inf. Theory, 60(4), 2014, 2080–2086], in the sense that our quantum MDS code has bigger minimum distance. | Liqin HU Qin YUE Xiaomeng ZHU | 2016 | Chinese Annals of Mathematics,Series B2016，37，6： | 2 |
| 7 | Two Ultraviolet Radiation Datasets that Cover China显示文摘Ultraviolet(UV) radiation has significant effects on ecosystems, environments, and human health, as well as atmospheric processes and climate change. Two ultraviolet radiation datasets are described in this paper. One contains hourly observations of UV radiation measured at 40 Chinese Ecosystem Research Network stations from 2005 to 2015. CUV3 broadband radiometers were used to observe the UV radiation, with an accuracy of 5%, which meets the World Meteorology Organization's measurement standards. The extremum method was used to control the quality of the measured datasets. The other dataset contains daily cumulative UV radiation estimates that were calculated using an all-sky estimation model combined with a hybrid model. The reconstructed daily UV radiation data span from 1961 to 2014. The mean absolute bias error and root-mean-square error are smaller than 30% at most stations, and most of the mean bias error values are negative, which indicates underestimation of the UV radiation intensity. These datasets can improve our basic knowledge of the spatial and temporal variations in UV radiation. Additionally, these datasets can be used in studies of potential ozone formation and atmospheric oxidation, as well as simulations of ecological processes. | Hui LIU Bo HU Yuesi WANG Guangren LIU Liqin TANG Dongsheng JI Yongfei BAI Weikai BAO Xin CHEN Yunming CHEN Weixin DING Xiaozeng HAN Fei HE Hui HUANG Zhenying HUANG Xinrong LI Yan LI Wenzhao LIU Luxiang LIN Zhu OUYANG Boqiang QIN Weijun SHEN Yanjun SHEN Hongxin SU Changchun SONG Bo SUN Song SUN Anzhi WANG Genxu WANG Huimin WANG Silong WANG Youshao WANG Wenxue WEI Ping XIE Zongqiang XIE Xiaoyuan YAN Fanjiang ZENG Fawei ZHANG Yangjian ZHANG Yiping ZHANG Chengyi ZHAO Wenzhi ZHAO Xueyong ZHAO Guoyi ZHOU Bo ZHU | 2017 | Advances in Atmospheric Sciences2017，34，7： | 2 |

| 10 | GAUSS PERIODS AND CYCLIC CODES FROM CYCLOTOMIC SEQUENCES OF SMALL ORDERS显示文摘Let p =ef +1 be an odd prime with positive integers e and f. In this paper, we calculate the values of Gauss periods of order e =3, 4, 6 over a finite field GF(q), where q is a prime with q≠p. As applications, several cyclotomic sequences of order e =3, 4, 6 are employed to construct a number of classes of cyclic codes over GF(q) with prime length. Under certain conditions, the linear complexity and reciprocal minimal polynomials of cyclotomic sequences are calculated, and the lower bounds on the minimum distances of these cyclic codes are obtained. | Hu Liqin Yue Qin Zhu Xiaomeng | 2014 | Journal of Electronics(China)2014，31，6： | 1 |
| 11 | Breeding of a New Clubroot-resistant Chinese Cabbage Variety, CCR11242显示文摘In this study,using Japanese radish cytoplasmic sterile line ' Half Green Cabbage'( HGC) and clubroot-resistant South Korean cabbage variety ' CR Cabbage King'( CCK) as experimental materials,self-incompatible DH lines were obtained by microspore culture.Through five generations of backcross,CCR11239,a clubroot-resistant radish cytoplasmic sterile line,was obtained.Through six generations of self-crossing,CCR11240,the maintainer line of CCR11239,was bred.After the cross of CCK and Luchunbai 1( 83- 1) and five generations of self-crossing,self-compatible line CCR11241 was obtained.Through crossing CCR11240 with CCR11241,the new cabbage variety CCR11242 was obtained.After variety comparison test,provincial regional test and production demonstration test,the new variety was registered in 2012.The average yield of CCR11242 reached 60 975 kg / hm2,which was improved by 142% compared with Luchunbai 1( 83- 1).The disease index of CCR11242 was 5.63,which was 88.13 lower than the control,indicating high resistance( HR) to clubroot. | Xuezhong XU Zhimei TIAN Hongli YANG Jingfeng HU Liqin ZHANG Mei LAN Hongju DUAN Jiangming HE | 2016 | Agricultural Biotechnology2016，5，5： | 1 |
| 12 | The effect of whey protein on viral infection and replication of SARS-CoV-2 and pangolin coronavirus in vitro显示文摘Dear Editor,Since severe acute respiratory syndrome coronavirus 2(SARSCoV-2)RNA has been detected in human breastmilk,infants’safety with breastmilk feeding is of great concern for women with coronavirus disease 2019(COVID-19).1 It is known that milk has antiviral properties.2 However,little is known about the antiviral property of human breastmilk to SARS-CoV-2 and its related pangolin coronavirus(GX_P2V).Here we present for the first time that whey protein from human breastmilk effectively inhibited both SARS-CoV-2 and GX_P2V by blocking viral attachment and viral replication at entry and even post entry.Moreover,human whey protein inhibited infectious virus production,as proved by the plaque assay.We found that whey protein from different species,such as cow and goat,also showed anti-coronavirus properties.Commercial bovine formula milk also showed similar anti-SARS-CoV-2 activity. | Huahao Fan Bixia Hong Yuqian Luo Qi Peng Liqin Wang Xiangshu Jin Yangzhen Chen Yunjia Hu Yi Shi Tong Li Hui Zhuang Yi-Hua Zhou Yigang Tong Kuanhui Xiang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 1 |
| 13 | Characteristics of soil water retention curve at macro-scale显示文摘Scale adaptable hydrological models have attracted more and more attentions in the hydrological modeling research community, and the constitutive relationship at the macro-scale is one of the most important issues, upon which there are not enough research activities yet. Taking the constitutive relationships of soil water movement--soil water retention curve (SWRC) as an example, this study extends the definition of SWRC at the micro-scale to that at the macro-scale, and aided by Monte Carlo method we demonstrate that soil property and the spatial distribution of soil moisture will affect the features of SWRC greatly. Furthermore, we assume that the spatial distribution of soil moisture is the result of self-organization of climate, soil, ground water and soil water movement under the specific boundary conditions, and we also carry out numerical experiments of soil water movement at the vertical direction in order to explore the relationship between SWRC at the macro-scale and the combinations of climate, soil, and groundwater. The results show that SWRCs at the macro-scale and micro-scale presents totally different features, e.g., the essential hysteresis phenomenon which is exaggerated with increasing aridity index and rising groundwater table. Soil property plays an important role in the shape of SWRC which will even lead to a rectangular shape under drier conditions, and power function form of SWRC widely adopted in hydrological model might be revised for most situations at the macro-scale. | TIAN FuQiang MOU LiQin HU HePing | 2009 | Science China(Technological Sciences)2009，52，10： | 1 |

| 19 | Bi/BiVO_(4)/NiFe-LDH heterostructures with enhanced photoelectrochemical performance for streptomycin detection显示文摘Streptomycin(STR)plays an essential role in bacterial infection treatments.Selectivity and sensitivity of photoelectrochemical(PEC)sensors are the two most important parameters,which can be measured using the photosensitivity of its active material.We prepared a novel PEC sensor to detect STR using Bi/BiVO4/LDH(layered double hydroxides)heterostructures as an active material,which is photoactive in the visible light wavelength range.The simultaneous presence of LDH and Bi/BiVO4 enhanced the material photocurrent response,which was linear to the STR concentrations in the 0.01–500 nmol/L range.The STR detection limit by this sensor was 0.0042 nmol/L.Our novel PEC-based sensing strategy includes using an ultra-sensitive and highly selective sensor for STR detection.Additionally,the two-pot synthesis of Bi/BiVO4/LDH developed in this work is environmentally friendly. | Liqin Yang Jun Zhao Caijun Wang Zheng Wang Cuijuan Xing Hao Guo Yuman Wang Zhiju Zhao Zhangji Hu Zhenyu Cai | 2021 | Journal of Environmental Sciences2021，33，11： | 1 |
| 20 | On the GF(p) Linear Complexity of Hall's Sextic Sequences and Some Cyclotomic-Set-Based Sequences显示文摘Klapper(1994) showed that there exists a class of geometric sequences with the maximal possible linear complexity when considered as sequences over GF(2), but these sequences have very low linear complexities when considered as sequences over GF(p)(p is an odd prime). This linear complexity of a binary sequence when considered as a sequence over GF(p) is called GF(p) complexity. This indicates that the binary sequences with high GF(2) linear complexities are inadequate for security in the practical application, while,their GF(p) linear complexities are also equally important, even when the only concern is with attacks using the Berlekamp-Massey algorithm [Massey, J. L., Shift-register synthesis and bch decoding, IEEE Transactions on Information Theory, 15(1), 1969, 122–127]. From this perspective, in this paper the authors study the GF(p) linear complexity of Hall's sextic residue sequences and some known cyclotomic-set-based sequences. | Xianmang HE Liqin HU Dong LI | 2016 | Chinese Annals of Mathematics,Series B2016，37，4： | 0 |
