| 1 | Climate change and its impacts on mountain glaciers during 1960–2017 in western China显示文摘Mountain glaciers are highly sensitive to climate change. In this paper, we systematically analyzed and discussed the responses of glaciers to climate change during 1960–2017 in western China by the methods of least squares and correlation analysis. Results show that the maximum temperature, minimum temperature, average temperature, and precipitation significantly increased in western China at the rates of 0.32°C/10 a, 0.48°C/10 a, 0.39°C/10 a, and 11.20 mm/10 a, respectively. However, the wind speed, hours of sunshine, snowfall, and snowy days displayed decreasing trends at the rates of –0.53 m/(s·10 a), 3.72 h/10 a, –2.90 mm/10 a, and –0.10 d/10 a, respectively. The annual percentage of glacier area decreased by approximately 0.42%, and the average glacier area decreased by 2.76 km^2/a. Meanwhile, glacial shrinkages were greater in the Altay Mountains, Tanggula Mountains, and Qilian Mountains than in the other mountainous regions. Glacier accumulation decreased while melt volume increased at a rate of 2.7×10~4 m^3/a. The area of melt volume was 1.3 times that of the glacier accumulation area. The glacier mass balance(GMB) decreased substantially at a rate of –14.0 mm/a, whereas the equilibrium line altitude(ELA) showed an increasing trend at a rate of 0.5 mm/a. After 1997, the mass was smaller than –500.0 mm, indicating a huge loss in glaciers. Furthermore, relationships between ELA and GMB and various climatic factors were established. Temperature and precipitation demonstrated a significantly negative correlation, whereas wind speed and snowy days had significantly positive correlations with GMB. Snowy days also exhibited a remarkably negative correlation with ELA. The strong warming trend and less snowy days were thought to be the main factors leading to glacial melting, whereas the increase in precipitation, and reductions of sunshine hours and wind speed might slow glacial melting. | LIU Yinge WANG Ninglian ZHANG Junhui WANG Lingang | 2019 | Journal of Arid Land2019，11，4： | 8 |
| 2 | Geochronology,Geochemistry and Petrogenesis of Diabase Dyke Swarms in East Tianshan,Xinjiang,NW China显示文摘Diabase dyke swarms are widespread in the East Tianshan and Beishan regions. LA-ICP-MS zircon U-Pb ages of these diabase vary from 305 Ma to 278 Ma, showing that these dykes were formed during Late Carboniferous-Early Permian magmatism. All diabase samples are subalkali calc-alkali, characterized by slight LREE and LILEs enrichment, and weak negative Ti, Nb and Ta anomalies. The diabase samples have positive εNd(t) values (>+3), high Sr isotopic compositions (initial 87Sr/86Sr values=0.7030-0.7097), and large variation of Pb isotopic compositions, indicating they were derived from a deplete mantle source. Regional geology and geochemistry evidences indicate that these diabase dyke swarms were generated in a lithosphere extensional setting and had the same magma sources. Initial magmas may be a mixture of depleted asthenosphere mantle and enriched lithospheric mantle during rapid magma ascending. | ZHANG Zuoheng CHAI Fengmei WANG Tuanhua CHENG Yanbo XU Lingang YUAN Shunda | 2012 | Acta Geologica Sinica(English Edition)2012，86，6： | 5 |

| 4 | Differentiation of storage time of wheat seed based on near infrared hyperspectral imaging显示文摘Seed aging during storage is one of the main factors that influence the quality of wheat seed.Current detection methods based on NIR spectra were mostly for group seeds,they had poor stability for single seed detection because of sample uniformity.In this study,the characteristic changes of single wheat seed during storage procedure were measured through hyperspectral imaging technology.Firstly,hyperspectral imaging data of wheat grain including six years from 2007 to 2012 had been collected.The original spectra showed clear difference in the band of 1400-1600 nm,which may be caused by the decreasing of moisture and protein content during storage;principal component analysis(PCA)was applied to analyze the spectral data of wheat grain including six years,the clustering chart of the principal components indicated that the grain between same or similar year have an clustering characteristic,and the characteristic difference would become obviously with the increasing of storage time;soft independent modeling of class analogy(SIMCA)was applied to classify the grain of different years,results showed that the classification accuracy of the dichotomy between adjacent years could reach 97.05%,and the accuracy of the mixed classification of six years could also reach 82.5%.These results indicated that hyperspectral imaging technology could be used to differentiate the quality change of wheat seed during different storage time,which could provide support for the intelligent monitoring of stored wheat seeds. | Dong Gao Guo Jian Wang Cheng Liang Kehong Lu Lingang Wang Jing Zhu Dazhou | 2017 | International Journal of Agricultural and Biological Engineering2017，10，2： | 1 |

| 7 | Wireless Communication Signal Strength Prediction Method Based on the K-nearest Neighbor Algorithm显示文摘Existing interference protection systems lack automatic evaluation methods to provide scientific, objective and accurate assessment results. To address this issue, this paper develops a layout scheme by geometrically modeling the actual scene, so that the hand-held full-band spectrum analyzer would be able to collect signal field strength values for indoor complex scenes. An improved prediction algorithm based on the K-nearest neighbor non-parametric kernel regression was proposed to predict the signal field strengths for the whole plane before and after being shield. Then the highest accuracy set of data could be picked out by comparison. The experimental results show that the improved prediction algorithm based on the K-nearest neighbor non-parametric kernel regression can scientifically and objectively predict the indoor complex scenes’ signal strength and evaluate the interference protection with high accuracy. | Zhao Chen Ning Xiong Yujue Wang Yong Ding Hengkui Xiang Chenjun Tang Lingang Liu Xiuqing Zou Decun Luo | 2019 | 国际计算机前沿大会会议论文集2019，，1： | 0 |
| 8 | A Privacy-Preserving TPA-aided Remote Data Integrity Auditing Scheme in Clouds显示文摘The remote data integrity auditing technology can guarantee the integrity of outsourced data in clouds. Users can periodically run an integrity auditing protocol by interacting with cloud server, to verify the latest status of outsourced data. Integrity auditing requires user to take massive time-consuming computations, which would not be affordable by weak devices. In this paper, we propose a privacy-preserving TPA-aided remote data integrity auditing scheme based on Li et al.’s data integrity auditing scheme without bilinear pairings, where a third party auditor (TPA) is employed to perform integrity auditing on outsourced data for users. The privacy of outsourced data can be guaranteed against TPA in the sense that TPA could not infer its contents from the returned proofs in the integrity auditing phase. Our construction is as efficient as Li et al.’s scheme, that is, each procedure takes the same time-consuming operations in both schemes, and our solution does not increase the sizes of processed data, challenge and proof. | Meng Zhao Yong Ding Yujue Wang Huiyong Wang Bingyao Wang Lingang Liu | 2019 | 国际计算机前沿大会会议论文集2019，，1： | 0 |
| 9 | Timing Synchronization and Ranging in Networked UAV-Aided OFDM Systems显示文摘The space-air-ground network architecture integrates satellite systems,aerial networks,and terrestrial networks,where the unmanned aerial vehicle(UAV)communication in the air segment has attracted particular interest and demonstrated tremendous potential in both military and civilian applications.Orthogonal frequency division multiplexing(OFDM)can be an effective solution to provide high rate and reliable transmission in UAV communication systems because of its high spectral efficiency and robustness against frequency selective fading.We herein focus our attention on two critical issues in our proposed UAV aided OFDM system,i.e.,timing synchronization and ranging.Moreover,extensive simulations are conducted for evaluation.Finally,we design a real-world field test for verifying the effectiveness of our proposed multi-UAV OFDM communication system. | Chaoxing Yan Jingjing Wang Lingang Fu Chunxiao Jiang Ming Chen Yong Ren | 2018 | Journal of Communications and Information Networks2018，3，4： | 0 |
