1Directional hydraulic fracturing to control hard-roof rockburst in coal mines显示文摘Hard roof is the main factor that induces rock-burst.In view of the present obvious weakness of control measures for hard roof rockburst in domestic collieries,the mechanism and field application of directional hydraulic fracturing technology for rock-burst prevention have been investigated in this paper using theoretical analysis and numerical simulation.The results show that the weighting span of the main roof and the released kinetic energy as well as the total elastic energy decreased greatly after the directional fracturing of hard roof with the mining progression,thereby reducing the rockburst hazard degree to coal body.The directional hydraulic fracturing technology was carried out in 6305 working face of Jisan Coal Mine to prevent rockburst.Field practices have proved that this technology is much simpler and safer to operate with better prevention effect compared with blasting.By optimizing the operation procedures and developing a new technology of automated high-pressure delivery pipe,the maximum fracturing radius now reaches more than 9 m and the borehole depth exceeds 20 m.Additionally,drilling cutting method was applied to monitor the stress of the coal mass before and after the fracturing,and the drill cuttings dropped significantly which indicates that the burst prevention effect of directional hydraulic fracturing technology is very remarkable.The research results of this paper have laid a theoretical and practical foundation for the widespread application of the directional hydraulic fracturing technology in China.Fan Jun Dou Linming He Hu Du Taotao Zhang Shibin Gui Bing Sun Xinglin 2012International Journal of Mining Science and Technology2012,22,2:28
2Quantum secure direct communication and authentication protocol with single photons显示文摘A quantum secure direct communication and authentication protocol is proposed by using single photons.An information transmission is completed by sending photons once in quantum channel,which improves the efficiency without losing the security.The protocol encodes identity-string of the receiver as single photons sequence,which acts as detection sequence and implements authentication.Before secret message is encoded as single photons sequence,it is encrypted with identity-string of the sender by using XOR operation,which defends quantum teleportation attack efficiently.The base identity-strings of the sender and the receiver are reused unconditionally secure even in noisy channel.Compared with the protocol proposed by Wang et al.(Phys Lett A,2006,358:256–258),the protocol in this study sends photons once in one transmission and defends most attacks including‘man-in-the-middle’attack and quantum teleportation attack efficiently.CHANG Yan XU ChunXiang ZHANG ShiBin YAN LiLi 2013Chinese Science Bulletin2013,58,36:16
3Controlled quantum secure direct communication and authentication protocol based on five-particle cluster state and quantum one-time pad显示文摘A controlled quantum secure direct communication and authentication protocol is proposed with a quantum one-time pad based on five-particle cluster state.Photon 4 in each five-particle cluster state is sent to the controller as permission.Unitary operation I(U)on photon4 according to identity-string of the receiver is used to forbid the controller to deduce secret message.The classical XOR operation serving as a one-time-pad is used to forbid external eavesdroppers to eavesdrop.Eavesdropping detection and identity authentication are implemented by previously shared reusable base identity-strings.In one transmission,one qubit of each five-particle cluster state is used as controller’s permission,and two qubits are used to transmit two classical bit information.Yan Chang Chunxiang Xu Shibin Zhang Lili Yan 2014Chinese Science Bulletin2014,59,21:13
4A survey on numerical simulations of drag and heat reduction mechanism in supersonic/hypersonic flows显示文摘Along with the survey on experimental investigations drawing attention to the drag and heat reduction mechanism, the authors simultaneously focus on the recent advances of numerical simulations on the schemes applied to supersonic/hypersonic vehicles. The CFD study has evolved as an irreplaceable method in scheme evaluation and aircraft optimization. Similar to our previous experimental survey, the advances in drag and heat reduction schemes are reviewed by similar kinds of mechanism in this article, namely the forward-facing cavity, the opposing jet, the aerospike, the energy deposition and their combinational configurations. This review article puts an emphatic eye on the flow conditions, numerical methods, novel schemes and analytical conclusions given in the simulations. Further, the multi-objective design optimization concept has also been illustrated due to the observable advantages of using CFD over experimental method, especially those performances conducted in drag reduction and thermal protection practice, and this would possess reference value in the design of aircraft system.Xiwan SUN Wei HUANG Min OU Ruirui ZHANG Shibin LI 2019Chinese Journal of Aeronautics2019,32,4:12
5Parametric estimation of discretely sampled Gamma-OU processes显示文摘The stationary Gamma-OU processes are recommended to be the volatility of the financial assets. A parametric estimation for the Gamma-OU processes based on the discrete observations is considered in this paper. The estimator of an intensity parameter λ and its convergence result are given, and the simulations show that the estimation is quite accurate. Assuming that the parameter λ is estimated, the maximum likelihood estimation of shape parameter c and scale parameter α, whose likelihood function is not explicitly computable, is considered. By means of the Gaver-Stehfest algorithm, we construct an explicit sequence of approximations to the likelihood function and show that it converges the true (but unkown) one. Maximizing the sequence results in an estimator that converges to the true maximum likelihood estimator and the approximation shares the asymptotic properties of the true maximum likelihood estimator. Some simulation experiments reveal that this method is still quite accurate in most of rational situations for the background of volatility.ZHANG Shibin,ZHANG Xinsheng & SUN Shuguang School of Management, Fudan University, Shanghai 200433, China Department of Mathematics, Shanghai Maritime University, Shanghai 200135, China 2006Science China Mathematics2006,49,9:7
6Promoted effect of zinc–nickel bimetallic oxides supported on HZSM-5 catalysts in aromatization of methanol显示文摘Zn/ZSM-5(NZ2) and Zn/Ni/ZSM-5(NZ3) as the catalysts for methanol to aromatics(MTA) were synthesized by a simple ultrasonic impregnation. The textural and acid properties of all catalysts were characterized using XRD, HRTEM, NH_3-TPD, Py-IR, XPS, XRF and TG techniques. The XRD and HRTEM results showed that the basic zeolite structures were not affected much with the incorporation of Zn and Ni species. However, great changes have taken place in acid properties. The Py-IR and XPS results indicated that the Zn-Lewis acid sites(ZnOH^+ species), which have stronger interaction with the zeolite framework compared with ZnO species, were generated at the expense of B acid sites with the incorporation of zinc species. Moreover, the product analysis results showed that the incorporation of zinc species promoted the primary aromatization by enhancing the dehydroaromatization and suppressing the cracking and subsequent H-transfer reaction. Furthermore, the addition of Ni species well inhibited the loss of zinc species by converting partial ZnO species to ZnOH^+ species, and thus improved the aromatization activity and catalyst stability. The catalytic performance results showed that the NZ3 possess higher conversion of methanol in a longer time and lower average rate of coke formation compared with NZ2. In addition,the NZ3 also exhibited the highest yield of BTX as the reaction proceeds.Yanming Jia Junwen Wang Kan Zhang Wei Feng Shibin Liu Chuanmin Ding Ping Liu 2017Journal of Energy Chemistry2017,26,3:7

8Source apportionment of perfluoroalkyl substances in surface sediments from lakes in Jiangsu Province,China:Comparison of three receptor models显示文摘Receptor models have been proved as useful tools to identify source categories and quantitatively calculate the contributions of extracted sources.In this study,sixty surface sediment samples were collected from fourteen lakes in Jiangsu Province,China.The total concentrations of C_4–C_(14)-perfluoroalkyl carboxylic acids and perfluorooctane sulfonic acid(∑_(12)PFASs) in sediments ranged from 0.264 to 4.44 ng/g dw(dry weight),with an average of 1.76 ng/g dw.Three commonly-applied receptor models,namely principal component analysis-multiple linear regression(PCA-MLR),positive matrix factorization(PMF) and Unmix models,were employed to apportion PFAS sources in sediments.Overall,these three models all could well track the ∑_(12) PFASs concentrations as well as the concentrations explained in sediments.These three models identified consistently four PFAS sources:the textile treatment sources,the fluoropolymer processing aid/fluororesin coating sources,the textile treatment/metal plating sources and the precious metal sources,contributing 28.1%,37.0%,29.7% and 5.3% by PCA-MLR model,30.60%,39.3%,22.4% and 7.7% by PMF model,and 20.6%,52.4%,20.2% and 6.8% by Unmix model to the ∑_(12) PFASs,respectively.Comparative statistics of multiple analytical methods could minimize individual-method weaknesses and provide convergent results to enhance the persuasiveness of the conclusions.The findings could give us a better knowledge of PFAS sources in aquatic environments.Yanjie Qi Zhuoshi He Shouliang Huo Jingtian Zhang Beidou Xi Shibin Hu 2017Journal of Environmental Sciences2017,29,7:6
9DCT domain filtering method for multi-antenna code acquisition显示文摘For global navigation satellite system(GNSS) signals in Gaussian and Rayleigh fading channel, a novel signal detection algorithm is proposed. Under the low frequency uncertainty case, after performing discrete cosine transform(DCT) to the outputs of the partial matched filter(PMF) for every antenna, the high order components in the transforming domain will be filtered, then the equalgain(EG) combination for the inverse discrete cosine transform(IDCT) reconstructed signal would be done subsequently. Thus,due to the different frequency distribution characteristics between the noise and signals, after EG combination, the energy of signals has almost no loss and the noise energy is greatly reduced. The theoretical analysis and simulation results show that the detection algorithm can effectively improve the signal-to-noise ratio of the captured signal and increase the probability of detection under the same false alarm probability. In addition, it should be pointed out that this method can also be applied to Rayleigh fading channels with moving antenna.Xiaojie Li Luping Xu Shibin Song Hua Zhang 2013Journal of Systems Engineering and Electronics2013,24,5:6

11Study on Quantum Trust Model Based on Node Trust Evaluation显示文摘Trust is the premise and foundation of secure communication,no matter in the quantum communication or classical communication.In fact,the existing quantum secure communication protocols and technologies are implicitly related to trust;or assume some trust premise in advance;or create or obtain a trust relationship.This paper studies on quantum trust model using node trust evaluation based on author’s own research achievements.We introduce the trust management into quantum communication network to build secure trusted quantum communication network based on evaluating the trust values of nodes,which are used to evaluate the reliability of each user.We put forward a scheme of quantum trust model based on node trust evaluation,and describe the thought and process of trust evaluation in detail based on the principles of quantum entanglement and quantum teleportation.We analyze the feasibility and safety of this scheme,which provides a new thinking and method for establishing a credible secure quantum communication network.ZHANG Shibin XIE Zhihai YIN Yifen CHANG Yan SHENG Zhiwei YAN Lili WANG Haichun HAN Guihua HUANG Yuanyuan WAN Guogen 2017Chinese Journal of Electronics2017,26,3:5
12Effect of Oxygen Concentration and Annealing Theatment on the Optical Properties of the Transparent Conductive CdIn_2O_4 Thin Films显示文摘Transparent conductive cadmium indium oxide films (CdIn2O4) were prepared by r.f. reactive sputtering from Cd-In alloy targets under an Ar-O2 atmosphere. Electrical conductivity of the order of 105Ω-1.m-1 and the optical transmission as high as 94% are easily attained by postdeposition annealing treatment. The effects of oxygen concentration in the reactive gas mixture and post-deposition annealing treatment on the optical transmittance as well as optical parameters, such as refractive index (n), extinction coefficient (k), real part (ε’) and imaginary part (ε') of the dielectric constant, were studied in the visible and near-infrared region.

13Quantum Communication Networks and Trust Management: A Survey显示文摘This paper summarizes the state of art in quantum communication networks and trust management in recent years.As in the classical networks,trust management is the premise and foundation of quantum secure communication and cannot simply be attributed to security issues,therefore the basic and importance of trust management in quantum communication networks should be taken more seriously.Compared with other theories and techniques in quantum communication,the trust of quantum communication and trust management model in quantum communication network environment is still in its initial stage.In this paper,the core technologies of establishing secure and reliable quantum communication networks are categorized and summarized,and the trends of each direction in trust management of quantum communication network are discussed in depth.Shibin Zhang Yan Chang Lili Yan Zhiwei Sheng Fan Yang Guihua Han Yuanyuan Huang Jinyue Xia 2019Computers, Materials & Continua2019,,9:3
14Deterministic secure quantum communication and authentication protocol based on three-particle W state and quantum one-time pad显示文摘Three-particle W states are used as decoy photons,and the eavesdropping detection rate reaches63%.The positions of decoy photons in information sequence are encoded with identity string ID of the legitimate users.Authentication is implemented by using previously shared identity string.State/j i is used as the carrier.One photon of/j i is sent to Bob;and Bob obtains a random key by measuring photons with bases dominated by ID.The bases information is secret to others except Alice and Bob.Both the eavesdropping detection based on three-particle W state and the secret ID ensure the security of the protocol.Unitary operations are not used.Yan Chang Shibin Zhang Lili Yan Jian Li 2014Chinese Science Bulletin2014,59,23:3
15Robust EPR-pairs-based quantum secure communication with authentication resisting collective noise显示文摘This work presents two robust quantum secure communication schemes with authentication based on Einstein-Podolsky-Rosen(EPR) pairs, which can withstand collective noises. Two users previously share an identity string representing their identities. The identity string is encoded as decoherence-free states(termed logical qubits), respectively, over the two collective noisy channels, which are used as decoy photons. By using the decoy photons, both the authentication of two users and the detection of eavesdropping were implemented. The use of logical qubits not only guaranteed the high fidelity of exchanged secret message, but also prevented the eavesdroppers to eavesdrop beneath a mask of noise.CHANG Yan ZHANG ShiBin LI Jian YAN LiLi 2014Science China(Physics,Mechanics & Astronomy)2014,57,10:3
16Flexible optoelectronic devices based on metal halide perovskites显示文摘The unique physical and chemical properties of metal halide perovskites predestine the devices to achieve high performance in optoelectronic field.Among the numerous high qualities of perovskites,their different low-temperature synthesis methods and preparation processes make them impressive and popular materials for flexible optoelectronic devices.Mainstream perovskite devices,for instance,solar cells,photodetectors and light-emitting diodes,have been fabricated on flexible substrates and show outstanding flexibility as well as high performance.For soft wearable electronic systems,mechanical flexibility is the premier condition.Compared to common devices based on rigid substrates,flexible perovskite devices are more practical and see widespread applications in energy,detection,display,and other fields.This review summarizes the recent progress of flexible perovskite solar cells,photodetectors and light-emitting diodes.The design and fabrication of different high-performance flexible perovskite devices are introduced.Various low-dimensional perovskite materials and configurations for flexible perovskite devices are presented.In addition,the limitations and challenges for further application are also briefly discussed.Hao Chen Hao Wang Jiang Wu Feng Wang Ting Zhang Yafei Wang Detao Liu Shibin Li Richard V.Penty Ian H.White 2020Nano Research2020,13,8:2

18Genetic architecture of maize yield traits dissected by QTL mapping and GWAS in maize显示文摘The study of yield traits can reveal the genetic architecture of grain yield for improving maize production.In this study, an association panel comprising 362 inbred lines and a recombinant inbred line population derived from X178 × 9782 were used to identify candidate genes for nine yield traits. High-priority overlap(HPO) genes, which are genes prioritized in a genome-wide association study(GWAS), were investigated using coexpression networks. The GWAS identified 51 environmentally stable SNPs in two environments and 36 pleiotropic SNPs, including three SNPs with both attributes. Seven hotspots containing 41 trait-associated SNPs were identified on six chromosomes by permutation. Pyramiding of superior alleles showed a highly positive effect on all traits, and the phenotypic values of ear diameter and ear weight consistently corresponded with the number of superior alleles in tropical and temperate germplasm. A total of 61 HPO genes were detected after trait-associated SNPs were combined with the coexpression networks. Linkage mapping identified 16 environmentally stable and 16 pleiotropic QTL.Seven SNPs that were located in QTL intervals were assigned as consensus SNPs for the yield traits.Among the candidate genes predicted by our study, some genes were confirmed to function in seed development. The gene Zm00001 d016656 encoding a serine/threonine protein kinase was associated with five different traits across multiple environments. Some genes were uniquely expressed in specific tissues and at certain stages of seed development. These findings will provide genetic information and resources for molecular breeding of maize grain yield.Xiao Zhang Zhiyong Ren Bowen Luo Haixu Zhong Peng Ma Hongkai Zhang Hongmei Hu Yikai Wang Haiying Zhang Dan Liu Ling Wu Zhi Nie Yonghui Zhu Wenzhu He Suzhi Zhang Shunzong Su Yaou Shen Shibin Gao 2022The Crop Journal2022,10,2:2
19Effects of surface states over core-shell Ni@SiO_2 catalysts on catalytic partial oxidation of methane to synthesis gas显示文摘In the present work, core-shell Ni@Si O2 catalysts were investigated in order to evaluate the relevance of catalytic activity and surface states of Ni core as well as Ni nanoparticles size to catalytic partial oxidation of methane(POM). The catalysts were characterized by N2 adsorption,H2-TPR, XRD, TEM and XPS techniques. The catalytic performance of the core-shell catalysts was found to be dependent on the surface states of catalyst, which influenced the formation of products. It was considered that carbon dioxide formed on the oxidized nickel sites(Ni O)and carbon monoxide produced on the reduced sites(Ni). The surface states of active metal in the dynamic were influenced both by the size of Ni core and the porosity of silica shell. However, the catalytic activity would be debased when the size of Ni core was under a certain extent,which can be ascribed to the fact the carbon deposition increased with the increasing content of Ni O. The effects of surface states of Ni@Si O2 catalyst on the catalytic performance were discussed and the reaction pathway over Ni core encapsulated inside silica shell was proposed.Chuanmin Ding Xiaofeng Gao Yulin Han Xishun Ma Junwen Wang Shibin Liu Kan Zhang 2015Journal of Energy Chemistry2015,24,1:2
