Security analysis of weighted network anonymity based on singular value decomposition by Yong ZENG, Lingjie ZHOU, Zhongyuan JIANG, Zhihong LIU, Jianfeng MA

“…The security of anonymous method based on singular value decomposition (SVD) in the privacy preserving of weighted social network was analyzed.The reconstruction method in network with integer weights and the inexact reconstruction method in network with arbitrary weighted were proposed.The <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mi>ε</mi> <mi>N</mi> </mfrac> </math></inline-formula> -tolerance was definited to measure its safety.It was also pointed out that the upper bound of ε (the reconfigurable coefficient) obtained in current spectral theories was so conservative that lacks of guidance.The reconfigurable coefficients of random networks,Barabasi-Albert networks,small world networks and real networks were calculated by experiment.Moreover,the reconfigurable coefficients of double perturbation strategies based on SVD were also tested.Experimental results show that weighted social networks have different tolerances on spectrum loss,and there is a close relationship between its tolerance and network parameters.…”

热采井口装置螺栓的蠕变及应力松弛规律研究 by 王亭沂, 曹旭祥, 李风, 孙爽

“…The stress relaxation phenomenon of bolt used in thermal recovery wellhead is studied experimentally under field conditions.The normal and high temperature tensile test,creep test and stress relaxation test are carried out respectively.The comparison of the experimental results shows that the strength of bolt material decreases and the plasticity increases at high temperature.The creep deformation is obvious under initial stress which explain the reason of stress relaxation in principle.The stress relaxation test,it can be found that the bolt stress have decreased obviously under the field condition.According to the stress relaxation experimental data,the stress relaxation formula under the field condition can be fitted.Finite element software is used to calculate the minimum pre-tightening load of bolts for each flange of KR21-370 thermal recovery wellhead device to achieve sealing.Combined with stress relaxation formula,the time required for flanges to fail due to stress relaxation of bolts is calculated.Solutions are proposed for bolts prone to failure.…”

Quantum cryptanalysis of lightweight block cipher Piccolo by Xiaoni DU, Xiangyu WANG, Lifang LIANG, Kaibin LI

“…By taking the characteristics of the structure of Piccolo algorithm RP permutation into consideration, a 3-round quantum distinguisher was proposed.Based on Grover meets Simon algorithm, the 6-round of quantum key recovery attack was given.The results show that the key can be recovered 56 bit with the time complexity 2 ²⁸ and the occupation of 464 qubit.Moreover, if attack rounds r＞6，the time complexity is 2 ^28+16(r-6), which is <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mn>1</mn> <mrow> <msup> <mn>2</mn> <mrow> <mn>68</mn></mrow> </msup> </mrow> </mfrac> </math></inline-formula> of Grover quantum brute-force search.The time complexity of the proposed attack method is significantly reduced compared with Grover search and is also better than that of traditional cryptanalysis, which lays a foundation for the subsequent research on quantum attacks of lightweight block ciphers.…”

Large dynamic range microwave photonics mixing system based on parallel DPMZM by Yongsheng GAO, Fangjing SHI, Jiajun TAN, Yangyu FAN

“…To solve the problems of nonlinear distortion and limited dynamic range of microwave photonics mixing system, a large dynamic range microwave photonics mixing system based on parallel dual parallel Mach-Zehnder modulator (DPMZM) was proposed.The parallel modulation of radio frequency and local oscillator signals was realized by using DPMZM.The third-order intermodulation distortion (IMD3) in the output intermediate frequency signal was eliminated by configuring the electro-optic modulation index of the two parallel channels and the working point of the modulators.Finally, the dynamic range of the system was improved.Simulation results show that the proposed scheme can suppress IMD3 by 17.7 dB and increase the SFDR to <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mn>127.8</mn><mtext> dB</mtext><mo>·</mo><msup> <mtext>Hz</mtext> <mrow> <mfrac> <mn>4</mn> <mn>5</mn> </mfrac> </mrow> </msup> </math></inline-formula> .…”

Parallel orchestration and deployment system for scalable heterogeneous service function chain supporting polymorphic network by Hao CHEN, Yuan YANG, Mingwei XU, Dan PEI, Yilin YOU

“…Aiming at the problem of second-level service function chain orchestration and deployment in the polymorphic data center with the scale of 10 000 servers, a scalable heterogeneous SFC parallel orchestration and deployment (SHOD) system was proposed.The scale-out orchestration time of service chain was reduced to seconds by partitioning the data center and adopting a parallel orchestrator design that minimizes resource usage.Using a mediator design model that satisfies the single-responsibility principle, the heterogeneous equipment scalable orchestration and deployment were realized as well as service function chain building chain.Experimental results show that in a data center with 10 000 servers, the scale-out orchestration time of SHOD system is reduced to <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mn>1</mn> <mrow> <mn>12</mn></mrow> </mfrac> </math></inline-formula> of the existing system-Daisy, while only 1.5 times CPU utilization overhead is introduced.…”

Integration and Comparative Analysis of Remote Sensing and In Situ Observations of Aerosol Optical Characteristics Beneath Clouds by Jing Chen, Jing Duan, Ling Yang, Yong Chen, Lijun Guo, Juan Cai

“…Lu reveals the following: (1) The AOD seasonal distribution frequencies under both clear-sky and cloudy-sky conditions are unimodal, with a values of 0.2∼0.6, and the inhomogeneity of the aerosol distribution in winter is evident; the seasonal difference in the AOD under clear-sky conditions is more significant, following the order of spring > summer > winter > autumn, and the AOD seasonal difference under cloudy-sky conditions is not obvious. (2) In the analysis of the AOD monthly variations, due to the influence of the meteorological conditions (high humidity, low wind speed) and pollutant transport, the AOD reached its peak in February (clear-sky: 0.63, cloudy-sky: 0.82). (3) Under clear-sky conditions, the negative correlation between the daily variations in AOD, and visibility is more significant during the daytime, and after 12:00, the AOD is positively correlated with <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>P</mi><msub><mi>M</mi><mrow><mn>2.5</mn></mrow></msub></mrow></semantics></math></inline-formula>; these results indicate that the AOD is affected mainly by pollutants and the boundary layer height. …”
