| 1 | An Efficient Multi-hop Broadcast Protocol for Emergency Messages Dissemination in VANETs显示文摘Black-burst based multi-hop broadcast protocols are effective means to disseminate Emergency messages(EMs)in Vehicular ad hoc networks(VANETs).However,Clear to broadcast(CTB)collision will happen and reduce propagation speed.Aiming at this problem,we propose a Black-burst and multi-channel based multihop broadcast(BMMB)protocol.Vehicles with multiple antennas can transmit and sense black-burst at different channels simultaneously based on multi-channel technology.Compared with existing black-burst based methods,BMMB shortens the iterative procedure to find out the optimal segment.Only one relay vehicle can be rapidly selected within the optimal segment without CTB collision.BMMB enables alternative broadcast methods,i.e.,unidirectional broadcast and multi-directional broadcast for straight roads and intersections respectively.Theoretical analysis is done for performance evaluation of BMMB,and simulation results demonstrate that BMMB performs better in terms of average one-hop delay and propagation speed. | WU Libing NIE Lei FAN Jing HE Yanxiang LIU Qin WU Dan | 2017 | Chinese Journal of Electronics2017，26，3： | 4 |

| 15 | PCR-based Assay for the Detection of Xanthomonas campestris pv. mangiferaeindicae Causing Bacterial Black Spot in Mango显示文摘[Objective] This study aimed to develop a PCR assay for detecting Xanthomonas campestris pv. mangiferaeindicae(Xcm) in culture and in planta. [Method] Primers(Xcm HF and Xcm HR) were designed based on the partial sequence of hrp B gene from xanthomonads to develop a PCR assay for Xcm. Furthermore, specificity and sensitivity of the primer pairs were analyzed in detection of genomic DNA and cell from Xcm. [Result] Amplication was positive only with genomic DNA from positive control ATCC11637 and 12 Xcm strains; no PCR products were amplified with genomic DNA from ten other xanthomonads and seven other bacterial species. The sensitivity of detection was 2.4 pg/μl genomic DNA, and 1.8 × 104CFU/ml cells. The primers also worked well for pathogen detection in direct PCR assays of Xcm colonies grown on liquid medium and in PCR assays of total DNA from leaf, branch and fruit lesions. [Conclusion] A PCR assay was successfully established for rapid detection of Xcm in culture and in planta. | Yanxiang QI He ZHANG Yixian XIE Xin ZHANG Ying LU Qunfang YU Huiqiang ZHANG Jinji PU | 2016 | Agricultural Science & Technology2016，17，6： | 0 |
| 16 | EARep:A Fully Distributed Exchange-Based Anonymity P2P Reputation System显示文摘A fully distributed exchange-based anonymity P2P reputation system-EARep was proposed.EARep can provide all the peer's anonymity in a fully distributed structured manner.In EARep,each peer's anonymity is achieved by changing pseudonyms.Analysis and simulation results showed that compared with DARep,which is an existing representative scheme,our system has two main features.First,EARep increased anonymity degree(measured by linkage probability) and was much more scalable than DARep.Specifically,with the same message overhead,EARep reduced the linkage probability by more than 50% compared with DARep.Alternatively,to achieve the same anonymity degree,the message overhead in EARep was less than 25% of that in DARep.Second,the service selection success ratio of EARep was greater than 90% even when the percentage of malicious peers was up to 70%,which makes our system robust to malicious behaviors of peers. | WEI Yunzhao HE Yanxiang HAO Liming | 2009 | Wuhan University Journal of Natural Sciences2009，14，4： | 0 |
| 17 | Process of Petri Nets Extension显示文摘To describe the dynamic semantics for the network computing, the concept on process is presented based on the semantic model with variable, resource and relation. Accordingly, the formal definition of process and the mapping rules from the specification of Petri nets extension to process are discussed in detail respectively. Based on the collective concepts of process, the specification of dynamic semantics also is constructed as a net system. Finally, to illustrate process intuitively, an example is specified completely. | ZHOU Guofu HE Yanxiang DU Zhuomin | 2006 | Wuhan University Journal of Natural Sciences2006，11，2： | 0 |
| 18 | Feedback Learning Based Dead Write Termination for Energy Efficient STT-RAM Caches显示文摘Spin-torque transfer RAM(STT-RAM) is a promising candidate to replace SRAM for larger Last level cache(LLC). However, it has long write latency and high write energy which diminish the benefit of adopting STT-RAM caches. A common observation for LLC is that a large number of cache blocks have never been referenced again before they are evicted. The write operations for these blocks, which we call dead writes, can be eliminated without incurring subsequent cache misses. To address this issue, a quantitative scheme called Feedback learning based dead write termination(FLDWT) is proposed to improve energy efficiency and performance of STT-RAM based LLC. FLDWT dynamically learns the block access behavior by using data reuse distance and data access frequency, and then classifies the blocks into dead blocks and live blocks. FLDWT terminates dead write block requests and improves the estimation accuracy via feedback information. Compared with STT-RAM baseline in the lastlevel caches, experimental results show that our scheme achieves energy reduction by 44.6% and performance improvement by 12% on average with negligible overhead. | SHEN Fanfan HE Yanxiang ZHANG Jun JIANG Nan LI Qing'an LI Jianhua | 2017 | Chinese Journal of Electronics2017，26，3： | 0 |
| 19 | An efficient method for detecting concurrency errors in object-oriented programs显示文摘Multicore and multi-threaded processors have become the norm for modern processors.Accordingly,concurrent programs have become more and more prevalent despite being difficult to write and understand.Although errors are highly likely to appear in concurrent code,conventional error detection methods such as model checking,theorem proving,and code analysis do not scale smoothly to concurrent programs.Testing is an indispensable technique for detecting concurrency errors,but it involves a great deal of manual work and is inefficient.This paper presents an automatic method for detecting concurrency errors in classes in object-oriented languages.The method uses a heuristic algorithm to automatically generate test cases that can effectively trigger errors.Then,each test case is executed automatically and a fast method is adopted to identify the actual concurrency error from anomalous run results.We have implemented a prototype of the method and applied it to some typical Java classes.Evaluation shows that our method is more effective and faster than previous work. | HE YanXiang WU Wei CHEN Yong | 2012 | Science China(Information Sciences)2012，55，12： | 0 |
| 20 | Seismic hazard analysis for engineering sites based on the stochastic finite-fault method显示文摘Seismic hazard analyses are mainly performed using either deterministic or probabilistic methods.However,there are still some defects in these statistical model-based approaches for regional seismic risk assessment affected by the near-field of large earthquakes.Therefore,we established a deterministic seismic hazard analysis method that can characterize the entire process of ground motion propagation based on stochastic finite-fault simulation,and we chose the site of the Xiluodu dam to demonstrate the method.This method can characterize earthquake source properties more realistically than other methods and consider factors such as the path and site attenuation of seismic waves.It also has high computational efficiency and is convenient for engineering applications.We first analyzed the complexity of seismogenic structures in the Xiluodu dam site area,and then an evaluation system for ground motion parameters that considers various uncertainties is constructed based on a stochastic finitefault simulation.Finally,we assessed the seismic hazard of the dam site area comprehensively.The proposed method was able to take into account the complexity of the seismogenic structures affecting the dam site and provide multi-level parameter evaluation results corresponding to different risk levels.These results can be used to construct a dam safety assessment system of an earthquake in advance that provides technical support for rapidly and accurately assessing the post-earthquake damage state of a dam,thus determining the influence of an earthquake on dam safety and mitigating the risk of potential secondary disasters. | Ruifang Yu Yisheng Song Xiangyun Guo Qianli Yang Xinjuan He Yanxiang Yu | 2022 | Earthquake Science2022，35，5： | 0 |
