| 1 | DCGAN Based Spectrum Sensing Data Enhancement for Behavior Recognition in Self-Organized Communication Network显示文摘Communication behavior recognition is an issue with increasingly importance in the antiterrorism and national defense area.However,the sensing data obtained in actual environment is often not sufficient to accurately analyze the communication behavior.Traditional means can hardly utilize the scarce and crude spectrum sensing data captured in a real scene.Thus,communication behavior recognition using raw sensing data under smallsample condition has become a new challenge.In this paper,a data enhanced communication behavior recognition(DECBR)scheme is proposed to meet this challenge.Firstly,a preprocessing method is designed to make the raw spectrum data suitable for the proposed scheme.Then,an adaptive convolutional neural network structure is exploited to carry out communication behavior recognition.Moreover,DCGAN is applied to support data enhancement,which realize communication behavior recognition under small-sample condition.Finally,the scheme is verified by experiments under different data size.The results show that the DECBR scheme can greatly improve the accuracy and efficiency of behavior recognition under smallsample condition. | Kaixin Cheng Lei Zhu Changhua Yao Lu Yu Xinrong Wu Xiang Zheng Lei Wang Fandi Lin | 2021 | China Communications2021，18，11： | 3 |

| 7 | Efficient splicing of the CPE intein derived from directed evolution of the Cryptococcus neoformans PRP8 intein显示文摘Intein-mediated protein splicing has been widely used in protein engineering;however,the splicing efficiency and extein specificity usually limit its further application.Thus,there is a demand for more general inteins that can overcome these limitations.Here,we study the trans-splicing of CPE intein obtained from the directed evolution of Cne PRP8,which shows that its splicing rate is~29-fold higher than that of the wild-type.When the+1 residue of Cextein is changed to cysteine,CPE also shows high splicing activity.Faster association and higher affinity may contribute to the high splicing rate compared with wild-type intein.These findings have important implications for the future engineering of inteins and provide clues for fundamental studies of protein structure and folding. | Qin Zhan Changhua Shi Yu Jiang Xianling Gao Ying Lin | 2023 | Acta Biochimica et Biophysica Sinica2023，55，8： | 0 |
| 8 | Study on Relationship Between Arc Behavior and Joint Forming in Cold Metal Transfer Welding Technology with Polarity⁃Exchanging显示文摘Cold metal transfer with polarity⁃exchanging is a new integrated welding technology based on MIG.Due to the alternation of the positive and negative polarities of the wire,favorable control upon the deposition rate and the welding shape coefficient was obtained in order to meet the desired joint design,and the related controlling principles and joint characteristics were reported.Droplet transfer physical behavior exhibited strong dependability on the studied welding parameters,such as welding voltage,welding current,wire feeding speed,and polarity⁃exchanging.This welding technology provides a new way for the welding of body⁃in⁃white(BIW)thin sheet with special demands.Moreover,the typical quality defects of MIG were greatly improved.Our study provides important technical information from the perspective of industrial application of MIG and sheds light on the higher application level of MIG in BIW welding. | Lijun Han Pengyu Lin Gengwei Zhang Lihui Zhong Changhua Liu | 2020 | Journal of Harbin Institute of Technology(New Series)2020，27，5： | 0 |
| 9 | Cranberry cultivated in China:UPLC-Q-TOF-MS analysis of its acidic ethanol extract and assessment of its anti-bacterial and anti-tumor activities in vitro显示文摘Cranberry,the fruit of Vaccinium macrocarpon Aiton,is becoming popular all over the world,due to its pleasant taste,nutraceutical value and biological activities.For a long time,98%of its yield has been from America.Since being introduced to China as an import in recent decades,cranberry has become a rapid success in the food industry even with the high transportation cost.Recently,V.macrocarpon was cultivated in the Northeast of China,and the area of cultivation has increased dramatically.Therefore,it is important to systematically determine the useful compounds and their activity in this“Made-in-China”cranberry.In the present study,the content of total phenolics,anthocyanins,proanthocyanidins,sugars and organic acids was determined.Our results demonstrated that domestic cranberry is a rich source of phenolics,anthocyanins,proanthocyanidins,sugars and organic acids.Analysis of the chemical composition of an acidic ethanol extract by UPLC-QTOF-MS identified 21 compounds as well as the contents determination of catechin and cyanidin-3-O-glucoside using RPHPLC.Furthermore,cranberry extract was tested for its anti-bacterial activity against five clinically important pathogens,as well as its inhibitory effect on the proliferation and migration of cancer cells in vitro.Our results demonstrated that cranberry produced in Chinese cultivation areas is a rich source of bioactive compounds and exhibited in vitro anti-microbial and anti-tumor activities.Our work provides essential information about the quality of domestic cranberry and facilitates the development of related industries. | Changhua Li Lin Wang Dianwen Wei Gaosheng Hu Xiaoning Zhang Zhihong Lou Qiong Zhang Jingming Jia Yongsheng Hou | 2019 | Journal of Polyphenols2019，1，1： | 0 |
