1TRIM35 mediates protection against influenza infection by activating TRAF3 and degrading viral PB2显示文摘Tripartite motif(TRIM)family proteins are important effectors of innate immunity against viral infections.Here we identified TRIM35 as a regulator of TRAF3 activation.Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon(IFN)in response to viral infection.777m35-deficient mice were more susceptible to influenza A virus(IAV)infection than were wild-type mice.TRIM35 promoted the RIG-Imediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1.IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3.TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2,thereby antagonizing its suppression of TRAF3 activation.Our in vitro and in vivo findings thus reveal novel roles of TRIM35,through catalyzing Lys63-or Lys48-linked polyubiquitination,in RIG-I antiviral immunity and mechanism of defense against IAV infection.Nan Sun Li Jiang Miaomiao Ye Yihan Wang Guangwen Wang Xiaopeng Wan Yuhui Zhao Xia Wen Libin Liang Shujie Ma Liling Liu Zhigao Bu Hualan Chen Chengjun Li 2020Protein & Cell2020,11,12:4
2Properties of strangelets in a new quark mass confinement model with one-gluon-exchange interaction显示文摘The properties of strangelets at zero temperature with a new quark model that includes both the confinement and one-gluonexchange interactions is studied in a fully self-consistent method.The charge and parameter dependence of the stability of strangelets are discussed.It is found that the one-gluon-exchange interaction lowers the energy of a strangelet,and consequently allows the strangelet to be absolutely stable.The stable strangelet radius in the present model is smaller in comparison with the absence of one-gluon-exchange interaction,and can thus be much less than that of a normal nucleus with the same baryon number,according to the strength of the confinement and one-gluon-exchange interactions.XIA ChengJun CHEN ShiWu PENG GuangXiong 2014Science China(Physics,Mechanics & Astronomy)2014,57,7:2
3Using GPU to calculate electron dose for hybrid pencil beam model显示文摘Hybrid pencil beam model(HPBM) offers an efficient approach to calculate the three-dimension dose distribution from a clinical electron beam.Still,clinical radiation treatment activity desires faster treatment plan process.Our work presented the fast implementation of HPBM-based electron dose calculation using graphics processing unit(GPU).The HPBM algorithm was implemented in compute unified device architecture running on the GPU,and C running on the CPU,respectively.Several tests with various sizes of the field,beamlet and voxel were used to evaluate our implementation.On an NVIDIA GeForce GTX470 GPU card,we achieved speedup factors of 2.18- 98.23 with acceptable accuracy,compared with the results from a Pentium E5500 2.80 GHz Dual-core CPU.GOU Chengjun LI Xia HOU Qing WU Zhangwen 2011Nuclear Science and Techniques2011,22,6:1
4Photon-counting distributed free-space spectroscopy显示文摘Spectroscopy is a well-established nonintrusive tool that has played an important role in identifying and quantifying substances,from quantum descriptions to chemical and biomedical diagnostics.Challenges exist in accurate spectrum analysis in free space,which hinders us from understanding the composition of multiple gases and the chemical processes in the atmosphere.A photon-counting distributed free-space spectroscopy is proposed and demonstrated using lidar technique,incorporating a comb-referenced frequency-scanning laser and a superconducting nanowire single-photon detector.It is suitable for remote spectrum analysis with a range resolution over a wide band.As an example,a continuous field experiment is carried out over 72 h to obtain the spectra of carbon dioxide(CO_(2))and semi-heavy water(HDO,isotopic water vapor)in 6 km,with a range resolution of 60 m and a time resolution of 10 min.Compared to the methods that obtain only column-integrated spectra over kilometer-scale,the range resolution is improved by 2-3 orders of magnitude in this work.The CO_(2)and HDO concentrations are retrieved from the spectra acquired with uncertainties as low as±1.2%and±14.3%,respectively.This method holds much promise for increasing knowledge of atmospheric environment and chemistry researches,especially in terms of the evolution of complex molecular spectra in open areas.Saifen Yu Zhen Zhang Haiyun Xia Xiankang Dou Tengfei Wu Yihua Hu Manyi Li Mingjia Shangguan Tianwen Wei Lijie Zhao Lu Wang Pu Jiang Chengjun Zhang Lixing You Leigang Tao Jiawei Qiu 2021Light(Science & Applications)2021,10,11:1
5Fusion of Internal Similarity to Improve the Accuracy of Recommendation Algorithm显示文摘Collaborative filtering algorithms(CF)and mass diffusion(MD)algorithms have been successfully applied to recommender systems for years and can solve the problem of information overload.However,both algorithms suffer from data sparsity,and both tend to recommend popular products,which have poor diversity and are not suitable for real life.In this paper,we propose a user internal similarity-based recommendation algorithm(UISRC).UISRC first calculates the item-item similarity matrix and calculates the average similarity between items purchased by each user as the user’s internal similarity.The internal similarity of users is combined to modify the recommendation score to make score predictions and suggestions.Simulation experiments on RYM and Last.FM datasets,the results show that UISRC can obtain better recommendation accuracy and a variety of recommendations than traditional CF and MD algorithms.Zejun Yang Denghui Xia Jin Liu Chao Zheng Yanzhen Qu Yadang Chen Chengjun Zhang 2021Journal on Internet of Things2021,3,2:0
