| 1 | Directional 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 | 2012 | International Journal of Mining Science and Technology2012，22，2： | 28 |
| 2 | A 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 | 2019 | Chinese Journal of Aeronautics2019，32，4： | 12 |
| 3 | Parametric 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 | 2006 | Science China Mathematics2006，49，9： | 7 |
| 4 | Improvements of heat resistance and adhesive property of condensed poly-nuclear aromatic resin via epoxy resin modification显示文摘A bisphenol epoxy resin was used as modifier to increase the heat resistance of condensed poly-nuclear aromatic(COPNA) resin. The basic properties of COPNA resin and modified resin were characterized by Fourier transform infrared spectroscopy(FT-IR), nuclear magnetic resonance spectroscopy(1H-NMR), vapor pressure osmometry(VPO) and elemental analysis(EA). Average structural parameters of resins were calculated by the improved Brown-Ladner method, and heat resistance of resins was tested by thermogravimetric analysis(TGA). The chemical structure, mechanical properties and heat resistivity of the resin/graphite composites prepared with different resins were compared. The results show that the adhesive property and heat resistance of COPNA resin can be remarkably improved by addition of 5 wt.% epoxy resin. The reason is that the reactions between epoxy groups of epoxy resin and hydroxyl groups of COPNA resin improve the heat resistance and adhesive property of COPNA resin. Electric motor brushes with good mechanical properties and low electrical resistivity were successfully prepared by using the modified resin as binder. | Wu Mingbo Wang Yuwei Jiang Wei Li Shibin Sun Qiqian Zheng Jingtang Qiu Jieshan | 2014 | Petroleum Science2014，11，4： | 5 |
| 5 | xperimental investigation on cumulative propagation of thin film buckling under cyclic load显示文摘As instrument technology is needed for rapid determination of the smaller,thinner and lighter specimens,more stringent demands are related to thin films such as micro-electro-mechanical systems(MEMS),dielectric coatings and electronic packaging.Therefore,the requirement for testing platforms for rapidly determine the mechanical properties of thin films is increasing.Buckling of a film/substrate system could offer a variety of applications,ranging from stretchable electronics to micro-nanoscale metrology.In this paper,a fatigue-loading device has been designed to make the cyclic loading available for investigating the cumulative propagation of thin film buckling.The straight side buckling of thin compressed titanium film with the thickness of 50 nm deposited on organic glass substrates is investigated by using an optical microscope.The cumulative buckling propagation under the cyclic loading of a sequence of peak compression with the frequency 1 Hz is recorded by CCD camera.The buckling extension lengths are calculated by digital image measurement technology. | WANG ShiBin JIA HaiKun LI LinAn SUN Heng CUI DiQiang GUO ZhenShan XUE XiuLi | 2011 | Science China(Technological Sciences)2011，54，6： | 4 |
| 6 | Mechanical and antibacterial properties of tannic acid-encapsulated carboxymethyl chitosan/polyvinyl alcohol hydrogels显示文摘The objective of this study was to develop an effective,potential wound dressing,which was constructed with a composite hydrogel of poly(vinyl alcohol)(PVA),carboxymethyl chitosan(CMC)and tannic acid(TA)by cryogenic treatment and freeze-drying method.The as-prepared TA-crosslinked PVA/CMC hydrogels exhibited interconnected pore structure with the mean pore size of roughly 3.7��m.We found that the compressive strength and stiffness of composite hydrogel increased when the TA component was introduced.However,the PVA/CMC-TA hydrogel possessed obviously lower swell property than that of the TA-free PVA/CMC hydrogel.We also found that the TA addition significantly improved the antibacterial capacity of the as-prepared hydrogel.Moreover,the inhibition zone test showed that the antibacterial activity of PVA/CMC-TA against S.aureus bacteria was greater than that against E.coli.The biological results indicated that the PVA/CMC-TA hydrogel exhibited good cytocompatibility to natural human dermal fibroblasts.In summary,our PVA/CMC-TA composite hydrogel exhibited promising mechanical and antibacterial properties,which showed great potential application as wound healing materials. | Xiaofan Feng Xiuling Hou Congjing Cui Shibin Sun Sahiya Sadik Shaohua Wu Fang Zhou | 2021 | Engineered Regeneration2021，2，1： | 2 |
| 7 | Process and Kinetics of Pyrolysis of COPNA Resin Synthesized from FCC Slurry显示文摘The mechanism and kinetics of pyrolysis of condensed poly-nuclear aromatic(COPNA) resins were investigated by non-isothermal thermogravimetry/derivative thermogravimetry measurements at various heating rates(10, 20 and 30 K/min) in nitrogen atmosphere. The changes in the functional groups, microstructure, and elemental composition of COPNA resins heated to different temperatures(200, 400, and 600 ℃) were investigated by Fourier transform infrared spectroscopy, scanning electron microscopy, and elemental analysis, respectively. The results of the pyrolytic experiments indicated that the pyrolysis process could be divided into three stages: an initial weight loss stage ranging from 225—450 ℃, a second weight loss stage ranging from 450—560 ℃, and a thermally stable stage occurring above 560 ℃. The heating rate had little effect on the pyrolysis process, and thermogravimetric parameters of COPNA resin, such as temperature at initial weight loss stage(Ti), temperature at final weight loss stage(Tf) and temperature at maximum weight loss stage(Tmax), shifted towards higher temperatures when the heating rate was increased. At higher heating temperature, the number of aliphatic chains and substituted groups attached to aromatic rings of the resultant sample was reduced, whereas the C/H ratio and porosity rate increased. Pyrolysis kinetics studies showed that the activation energy(E) range for the first and second weight loss stages was 150—210 k J/mol and 210—275 k J/mol, respectively, which showed that the mechanism of thermal decomposition differed from that of the weight loss stages. The k0 value was in the orders of between 1011/s and 1018/s when the activation energy was less than 250 k J/mol. When the activation energiy was greater than 250 k J/mol, there was a linearly increasing relationship between k0 and E. | Li Shibin Sun Qiqian Jiang Wei Teng Chuanliang Wu Mingbo | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，2： | 1 |

| 9 | Curing Mechanism of Condensed Polynuclear Aromatic Resin and Thermal Stability of Cured Resin显示文摘In order to improve the thermal stability of condensed polynuclear aromatic(COPNA) resin synthesized from vacuum residue, 1,4-benzenedimethanol was added to cure COPNA resin. The curing mechanism was investigated by proton nuclear magnetic resonance spectrometry, solid carbon-13 nuclear magnetic resonance spectrometry and Fourier transform infrared spectroscopy. Microstructures of the uncured and the cured COPNA resins were studied by scanning electron microscopy and X-ray diffractometry. The thermal stability of COPNA resins before and after curing was tested by thermogravimetric analysis. The element composition of the cured COPNA resin heated at different temperatures was analyzed by an element analyzer. The results showed that the uncured COPNA resin reacted with the cross-linking agent during the curing process, and the curing mechanism was confirmed to be the electrophilic substitution reaction. Compared with the uncured COPNA resin, the cured COPNA resin had a smooth surface, well-ordered and streamlined sheet structure with more crystalline solids, better molecular arrangement and orientation. The weight loss process of the uncured and cured COPNA resins was divided into three stages. Carbon residue of the cured COPNA resin was 41.65% at 600 ℃, which was much higher than 25.02% of the uncured COPNA resin, which indicated that the cured COPNA resin had higher thermal stability. | Li Shibin Sun Qiqian Wang Yuwei Wu Mingbo Zhang Zailong | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，2： | 1 |

| 12 | Electrospun chitosan nanofibers for wound healing application显示文摘Electrospun nanofibers have been considered as relatively ideal material system for the design and construction of surgical wound dressings in the past few decades.Although there are lots of other biopolymers employed for electrospinning,chitosan is one of the most important biopolymers for the fabrication of electrospun nanofibers,due to its nontoxic,antibacterial,biocompatible as well as biodegradable properties.Electrospun chitosan nanofibers with random or aligned fiber structure can further be cross-linked by physical,chemical and ionic crosslinking methods.The as-crosslinked electrospun chitosan nanofibrous membranes possess enhanced wet stability,improved mechanical property and good biocompatibility,which are necessary for wound healing application.The present work reviews the recent studies on the design and development of electrospun chitosan nanofibers and their applications for wound healing,such as antibacterial materials,hemostatic dressings,angiogenesis and immune regulation. | Congjing Cui Shibin Sun Shaohua Wu Shaojuan Chen Jianwei Ma Fang Zhou | 2021 | Engineered Regeneration2021，2，1： | 0 |
| 13 | Quantum Secure Direct Communication Protocol with Mutual Authentication Based on Single Photons and Bell States显示文摘Quantum secure direct communication(QSDC)can transmit secret messages directly from one user to another without first establishing a shared secret key,which is different from quantum key distribution.In this paper,we propose a novel quantum secure direct communication protocol based on signal photons and Bell states.Before the execution of the proposed protocol,two participants Alice and Bob exchange their corresponding identity IDA and IDB through quantum key distribution and keep them secret,respectively.Then the message sender,Alice,encodes each secret message bit into two single photons(|01>or|10>)or a Bell state(1|φ^(+)>=1/√2(|0>|-|1>1>)),and composes an ordered secret message sequence.To insure the security of communication,Alice also prepares the decoy photons and inserts them into secret message sequence on the basis of the values of IDA and IDB.By the secret identity IDA and IDB,both sides of the communication can check eavesdropping and identify each other.The proposed protocol not only completes secure direct communication,but also realizes the mutual authentication.The security analysis of the proposed protocol is presented in the paper.The analysis results show that this protocol is secure against some common attacks,and no secret message leaks even if the messages are broken.Compared with the two-way QSDC protocols,the presented protocol is a one-way quantum communication protocol which has the immunity to Trojan horse attack.Furthermore,our proposed protocol can be realized without quantum memory. | Lili Yan Shibin Zhang Yan Chang Zhibin Sun Zhiwei Sheng | 2020 | Computers, Materials & Continua2020，，6： | 0 |
| 14 | Robust containment control for a class of heterogeneous uncertain nonlinear multi-agent systems in lower triangular form显示文摘This paper studies the robust containment control problem for a class of nonlinear multi-agent systems in lower triangular form with parameter uncertainty.The agents are heterogenous with the particularity that the dynamics of the leaders are totally different from those of the followers.The interconnection topology is described by a general directed graph.Based on the distributed internal model,the robust containment control problem is first converted into the stabilisation problem for an augmented network.A distributed state feedback control is then proposed to solve the stabilisation problem of the subsequent augmented network by the block backstepping technique.Under the proposed control,all the followers’outputs will converge to the convex hull spanned by the leaders. | Jing Zhao Shibin Shen Fei Xie Yanfei Sun Fengyu Xu | 2021 | Journal of Control and Decision2021，8，3： | 0 |
| 15 | A Novel Semi-Quantum Private Comparison Scheme Using Bell Entangle States显示文摘Private comparison is the basis of many encryption technologies,and several related Quantum Private Comparison(QPC)protocols have been published in recent years.In these existing protocols,secret information is encoded by using conjugate coding or orthogonal states,and all users are quantum participants.In this paper,a novel semi-quantum private comparison scheme is proposed,which employs Bell entangled states as quantum resources.Two semi-quantum participants compare the equivalence of their private information with the help of a semi-honest third party(TP).Compared with the previous classical protocols,these two semi-quantum users can only make some particular action,such as to measure,prepare and reflect quantum qubits only in the classical basis fj0i;j1ig,and TP needs to perform Bell basis measurement on reflecting qubits to obtain the results of the comparison.Further,analysis results show that this scheme can avoid outside and participant attacks and its’qubit efficiency is better than the other two protocols mentioned in the paper. | Yuhua Sun Lili Yan Zhibin Sun Shibin Zhang Jiazhong Lu | 2021 | Computers, Materials & Continua2021，，3： | 0 |

| 17 | Perpulmonary Device Closure of Patent Ductus Arteriosus with Minimum Diameter More Than 4 mm in Infants显示文摘Background:Closure of large patent ductus arteriosus(PDA)in older children has been accomplished using surgical and percutaneous techniques with remarkable outcomes.However,outcomes amongst infants have been variable with several drawbacks.Here we describe a novel minimally invasive technique,a product of mini-thoracotomy and traditional percutaneous technique skills,accomplished exclusively under echocardiography guidance.Methods:Symptomatic infants with a significant left-to-right shunt from PDA measuring more than 4 mm were selected.The symptoms were varying degrees of tachypnea,tachycardia,heart failure,failure to thrive,recurrent respiratory tract infections,or intensive care unit treatment for a longer duration.Through a left parasternal mini-thoracotomy,two parallel purse-string sutures were placed on the pulmonary trunk.After purse-string circle puncture,under exclusively transesophageal echocardiography guidance,a device secured to the safety-suture was implanted on the ascending aorta via pulmonary trunk using a specially designed set.The safety-suture prevented device migration in case of dislocation.The basic demographics,PDA size,device size and type,intrapulmonary manipulation time,operation time,PDA parameters(length,diameter,type of duct),redeployment of the device,residual shunt,and retention of safety-suture were all recorded and analyzed.The follow-up was done with transthoracic echocardiography on the 2^(nd)postoperative day,1,3,6,and 12 months,and yearly thereafter.Results:Fifty-two infants with a mean age of 8 months±2.8 months(Interquartile range=0)underwent Perpulmonary device closure of PDA.Successful PDA occlusion was accomplished event-free in all subjects.The mean PDA,mean device,and mean operation time were 5.6 mm±1.4 mm,7.9 mm±1.7 mm,and 61.2 min±12.9 min,respectively.The immediate acceptable residual shunt was noted among 3 subjects and disappeared at a 1-month follow-up.Eighteen infants had retained safety-suture for added safety.There were no reports of the device or procedure-related complications.Conclusion:Perpulmonary device closure is an effective and safe approach to PDA with a diameter measuring>4 mm among infants.The safety-suture,in case of dislocation,prevents migration and associated complications. | Shibin Sun Geoffrey J.Changwe Zeeshan Farhaj Hongxin Li Yuekun Sun Zhongzheng Kong | 2022 | Congenital Heart Disease2022，17，4： | 0 |
| 18 | Long-term outcomes of brainstem arteriovenous malformations after different management modalities: a single-centre experience显示文摘Objective The aims of this study are to clarify the long-term outcomes of brainstem arteriovenous malformations(AVMs)after different management modalities.Methods The authors retrospectively reviewed 61 brainstem AVMs in their institution between 2011 and 2017.The rupture risk was represented by annualised haemorrhagic rate.Patients were divided into five groups:conservation,microsurgery,embolisation,stereotactic radiosurgery(SRS)and embolisation+SRS.Neurofunctional outcomes were evaluated by the modified Rankin Scale(mRS).Subgroup analysis was conducted between different management modalities to compare the long-term outcomes in rupture or unruptured cohorts.Results All of 61 brainstem AVMs(12 unruptured and 49 ruptured)were followed up for an average of 4.5 years.The natural annualised rupture risk was 7.3%,and the natural annualised reruptured risk in the ruptured cohort was 8.9%.13 cases were conservative managed and 48 cases underwent intervention(including 6 microsurgery,12 embolisation,21 SRS and 9 embolisation+SRS).In the selection of interventional indication,diffuse nidus were often suggested conservative management(p=0.004)and nidus involving the midbrain were more likely to be recommended for intervention(p=0.034).The risk of subsequent haemorrhage was significantly increased in partial occlusion compared with complete occlusion and conservative management(p<0.001,p=0.036,respectively).In the subgroup analysis,the follow-up mRS scores of different management modalities were similar whether in the rupture cohort(p=0.064)or the unruptured cohort(p=0.391),as well as the haemorrhage-free survival(p=0.145).In the adjusted Bonferroni correction analysis of the ruptured cohort,microsurgery and SRS could significantly improve the obliteration rate compared with conservation(p<0.001,p=0.001,respectively)and SRS may have positive effect on avoiding new-onset neurofunctional deficit compared with microsurgery and embolisation(p=0.003,p=0.003,respectively).Conclusions Intervention has similar neurofunctional outcomes as conservation in these brainstem AVM cohorts.If intervention is adopted,partial obliteration should be avoided because of the high subsequent rupture risk. | Yu Chen Ruinan Li Li Ma Xiangyu Meng Debin Yan Hao Wang Xun Ye Hengwei Jin Youxiang Li Dezhi Gao Shibin Sun Ali Liu Shuo Wang Xiaolin Chen Yuanli Zhao | 2021 | Stroke & Vascular Neurology2021，6，1： | 0 |
| 19 | Measure-Resend Semi-Quantum Private Comparison Scheme Using GHZ Class States显示文摘Quantum private comparison is an important topic in quantum cryptography.Recently,the idea of semi-quantumness has been often used in designing private comparison protocol,which allows some of the participants to remain classical.In this paper,we propose a semi quantum private comparison scheme based on Greenberge-Horne-Zeilinger(GHZ)class states,which allows two classical participants to compare the equality of their private secret with the help of a quantum third party(server).In the proposed protocol,server is semi-honest who will follow the protocol honestly,but he may try to learn additional information from the protocol execution.The classical participants’activities are restricted to either measuring a quantum state or reflecting it in the classical basis{0,1}.In addition,security and efficiency of the proposed schemes have been discussed. | Lili Yan Yan Chang Shibin Zhang Qirun Wang Zhiwei Sheng Yuhua Sun | 2019 | Computers, Materials & Continua2019，，8： | 0 |
