| 1 | Automatic Malware Classification via PRICoLBP显示文摘Creating effective features is a critical issue in malware analysis. It requires a proper tradeoff between discriminative power and invariance. Previous studies have shown that it is fairly effective to design features based on the binary code. However, the current existing binary-based features seldom take into consideration the problem of obfuscation, such as relocated sections, incomplete code and redundant operations. In this paper, we propose a novel Pairwise rotation invariant co-occurrence local binary pattern(PRICo LBP) feature, and further extend it to incorporate the Term frequency-inverse document frequency(TFIDF) transform. Different from other static analysis techniques, our method not only achieves better linear separability, but also appears to be more resilient to obfuscation. In addition, we evaluate PRICo LBPTFIDF comprehensively on three datasets from different perspectives, e.g., classification performance, classifier selection and performance against obfuscation. What's more,we compare our PRICoLBP-TFIDF method with other techniques, and demonstrate that PRICo LBP-TFIDF is quite an efficient and effective tradeoff between discriminative power and invariance. | YAN Hanbing ZHOU Hao ZHANG Honggang | 2018 | Chinese Journal of Electronics2018，27，4： | 10 |
| 2 | WAF-Based Chinese Character Recognition for Spam Image Filtering显示文摘We address the problem of filtering image spam, a kind of rapidly spread spam in which the text is embedded into images to defeat text-based spam filter.Particularly, we focus on image spam with Chinese text as 'spam' which is a more challenging task. A popular way to detect image spam is by Optical character recognition(OCR) system, which detects and recognizes the embedded text, then followed by a text classifier that discriminate spam from ham. However, spammers start to obscure image text to prevent OCR system discovering the spam text. To compensate for the shortcomings of OCR system, a novel method which essentially is a keyword reconstruction algorithm based on Word activation force(WAF) model is proposed. It is effective on discovering keywords, hence is benefit for the later classification stage and notably improve the performance of image spam filtering. The experimental results on a personal data set of spam images(publicly available) validate the effectiveness of our approach that outperforms the original OCR system in practical usage with complex background in image spam. | LI Siyuan LI Ruiguang XU Yuan ZHOU Hao YAN Hanbing XU Bin ZHANG Honggang | 2018 | Chinese Journal of Electronics2018，27，5： | 3 |
| 3 | Filtering Chinese Image Spam Using Pseudo-OCR显示文摘For image spam filtering, the Optical character recognition(OCR) based methods often achieve a better performance due to the more complex structure of recognizing corresponding text. However, applying traditional OCR techniques usually introduced shortcomings like the expensive computational cost, vulnerability to image noises and artificial interferences, especially for Chinese image spam filtering. So, by optimizing recognition procedure of traditional OCR, we propose the idea of pseudo-OCR more suitable for Chinese image spam filtering. During which discriminating the potential image spam character features from ham ones is sufficient, instead of recognizing them. What's more, a novel Chinese key-point based character feature specific for pseudo-OCR is also devised and extracted using a carefully designed algorithm, which outperforms classic corner detection methods in finding such key-points. Experiment results show that our proposed system usually has a better performance than traditional OCR based method while maintaining a low false positive rate. | XU Bin LI Ruiguang LIU Yashu YAN Hanbing LI Siyuan ZHANG Honggang | 2015 | Chinese Journal of Electronics2015，24，1： | 2 |
| 4 | HiAtGang:How to Mine the Gangs Hidden Behind DDoS Attacks显示文摘Identifying and determining behaviors of attack gangs is not only an advanced stage of the network security event tracing and analysis,but also a core step of large-scale combat and punishment of cyber attacks.Most of the work in the field of distributed denial of service(DDoS)attack analysis has focused on DDoS attack detection,and a part of the work involves the research of DDoS attack sourcing.We find that very little work has been done on the mining and analysis of DDoS attack gangs.DDoS attack gangs naturally have the attributes of human community relations.We propose a framework named HiAtGang,in which we define the concept of the gang detection in DDoS attacks and introduce the community analysis technology into DDoS attack gang analysis.Different attacker clustering algorithms are compared and analyzed.Based on analysis results of massive DDoS attack events that recorded by CNCERT/CC(The National Computer Network Emergency Response Technical Team/Coordination Center of China),the effective gang mining and attribute calibration have been achieved.More than 250 DDoS attack gangs have been successfully tracked.Our research fills the gaps in the field of the DDoS attack gang detection and has supported CNCERT/CC in publishing“Analysis Report on DDoS Attack Resources”for three consecutive years and achieved a good practical effect on combating DDo S attack crimes. | ZHU Tian QIU Xiaokang RAO Yu YAN Hanbing ZHOU Yu SHI Guixin | 2022 | Chinese Journal of Electronics2022，31，2： | 2 |

| 6 | Superior single-mode lasing in a self-assembly CsPbX3 microcavity over an ultrawide pumping wavelength range显示文摘All-inorganic perovskite micro/nanolasers are emerging as a class of miniaturized coherent photonic sources for many potential applications,such as optical communication,computing,and imaging,owing to their ultracompact sizes,highly localized coherent output,and broadband wavelength tunability.However,to achieve singlemode laser emission in the microscale perovskite cavity is still challenging.Herein,we report unprecedented single-mode laser operations at room temperature in self-assembly Cs Pb X3 microcavities over an ultrawide pumping wavelength range of 400–2300 nm,covering one-to five-photon absorption processes.The superior frequency down-and upconversion single-mode lasing manifests high multiphoton absorption efficiency and excellent optical gain from the electron–hole plasma state in the perovskite microcavities.Through direct compositional modulation,the wavelength of a single-mode Cs Pb X3 microlaser can be continuously tuned from blue-violet to green(427–543 nm).The laser emission remains stable and robust after long-term high-intensity excitation for over 12 h(up to 4.3×107 excitation cycles)in the ambient atmosphere.Moreover,the pump-wavelength dependence of the threshold,as well as the detailed lasing dynamics such as the gain-switching and electron–hole plasma mechanisms,are systematically investigated to shed insight into the more fundamental issues of the lasing processes in Cs Pb X3 perovskite microcavities. | GUOEN WENG JIYU YAN SHENGJIE CHEN CHUNHU ZHAO HANBING ZHANG JIAO TIAN YUEJUN LIU XIAOBO HU JIAHUA TAO SHAOQIANG CHEN ZIQIANG ZHU HIDEFUMI AKIYAMA JUNHAO CHU | 2021 | Photonics Research2021，9，1： | 1 |

| 13 | CTS: Combine Temporal Influence and Spatial Influence for Time-Aware POI Recommendation显示文摘As location-based social network (LBSN) services become more popular in people’s lives, Point of Interest (POI) recommendation has become an important research topic.POI recommendation is to recommend places where users have not visited before. There are two problems in POI recommendation: sparsity and precision. Most users only check-in a few POIs in an LBSN. To tackle the sparse problem in a certain extent, we compute the similarity between the check-in datasets of different times. For the precision problem, we incorporate temporal information and geographical information. The temporal information will influence how the user chooses and allow the user to visit different distance point on different day. The geographical information is also used as a control for points which are too far away from the user’s check-in data. Our experimental results on real life LBSN datasets show that the proposed approach outperforms the other POI recommendation methods substantially. | Hanbing Zhang Yan Yang Zhaogong Zhang | 2016 | 国际计算机前沿大会会议论文集2016，，1： | 0 |
| 14 | Factors Affecting Online Learning Stickiness from the Perspective of Comprehensive Learning Theory显示文摘Based on the concept of learning stickiness,this study constructed a model of influencing factors among the elements of online learning content,interaction,incentive,satisfaction,and learning stickiness from Comprehensive Learning Theory.Structural equation modeling was used to analyze the interaction and influence effects among the factors.It is found that the content,interaction,and incentive in Comprehensive Learning Theory had a significant positive impact on learning stickiness from the total effect analysis.From the direct effect analysis,the influence of content and interaction on learning stickiness was not substantial,but the influence of incentive and satisfaction on learning stickiness was significant.From the perspective of mediation effect analysis,incentive and satisfaction were critical mediating variables for the influence of content and interaction on learning stickiness.This study put forward suggestions and strategies for online teaching,providing a reference for teachers to carry out online education. | MIAO Dongling WU Zhao YAN Hanbing | 2022 | Frontiers of Education in China2022，17，1： | 0 |
| 15 | 4-5 Dielectronic Recombination of Li-like Argon Ions at the CSRm显示文摘The main cooler storage ring (CSRm) equipped with an electron-cooler creates an ideal platform for dielectronicrecombination (DR) experiments. In order to fully understand our DR experimental setup and especially the electronenergy detuning system, we have performed a DR calibration experiment using the Li-like argon ions at theCSRm. The Ar15+ has a simple electronic structure so the DR spectrum can be calculated with an ultra-highprecision and compared with the existing experimental data. The experiment was carried out at the relative energyfrom 0 to 32 eV that includes all DR resonances associated with 2s1=2 ! 2p1=2 and most of the 2s1=2 ! 2p3=2excitations. | Huang Zhongkui Ma Xinwen Wen Weiqiang Wang Hanbing Chuai Xiaoya Zhu Xiaolong Zhao Dongmei Yuan Youjin Mao Lijun Li Jie Ma Xiaoming Yan Tailai Yang Jiancheng Xia Jiawen Xu Xin Zhu Linfan | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 16 | 4-6 Measurement of the Ratio of C3+ and O4+ Ions Produced by ECR Source to Prepare a Laser Cooling Experiment at Storage Rings显示文摘The cooling of heavy ions can provide high-quality beams that are especially important for high-precisionexperimental nuclear and atomic physics. The laser cooling of relativistic C3+ ion beams at the experimental coolerstorage ring (CSRe) is being currently prepared at Institute of Modern Physics (IMP) in Lanzhou. An electroncyclotron resonance ion source (ECRIS) will be used to produce C3+ ion beams. Meanwhile, O4+ ions could alsobe produced due to residual gas because of the same mass-to-charge ratio. Therefore, both C3+ and O4+ ion beamswill be injected and circulate in a storage ring during the laser cooling experiment at the same time. A higher ratioof C3+ ions will lead to a better result for the laser cooling experiment. | Zhu Xiaolong Wen Weiqiang Ma Xinwen Li Jinyu Feng Wentian Zhang Ruitian Yan Shuncheng Guo Dalong Hai Bang Qian Dongbin Zhang Pengju Xu Shenyue Zhao Dongmei Yang Jie Zhang Dacheng Li Bin Gao Yong Huang Zhongkui Wang Hanbing | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 17 | Ne^(8+)重离子碰撞氩二聚体碎裂中的取向效应研究显示文摘The experiment was carried out using the Reaction Microscope mounted at the 320 kV platform for multidisciplinary research with highly charged ions at the Institute of Modern Physics,CAS[1,2].For reaction channel of(Ar2)^(2+)→Ar^(+)+Ar^(+),the kinetic energy release(KER)distribution clearly shows two peaks.The left peak locates at 3.7 eV approximately,and the right one lies at about 5.3 eV.From the classical reflection approximation KER/(Z1-Z2)=R,the internuclear distance R can be deduced.We find that the corresponding internuclear distance of the left peak is 3.8˚A,which is the equilibrium internuclear distance of the Ar2 dimer.This indicates that coulomb explosion takes place immediately after the double ionization process,without the involvement of the geometry change of the cluster ion.Therefore,the left peak dominantly arises from two-site double ionization. | Zhu Xiaolong Yan Shuncheng Feng Wentian Ma Xinwen Chuai Xiaoya Guo Dalong Gao Yong Zhang Ruitian Zhang Pengju Zhang Shaofeng Zhao Dongmei Xu Shenyue Wang Hanbing Huang Zhongkui Qian Dongbin | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |
