| 1 | Progress in octahedral spherical hohlraum study显示文摘In this paper,we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study.From our theoretical study,the octahedral spherical hohlraums with 6 Laser Entrance Holes(LEHs)of octahedral symmetry have robust high symmetry during the capsule implosion at hohlraum-to-capsule radius ratio larger than 3.7.In addition,the octahedral spherical hohlraums also have potential superiority on low backscattering without supplementary technology.We studied the laser arrangement and constraints of the octahedral spherical hohlraums,and gave a design on the laser arrangement for ignition octahedral hohlraums.As a result,the injection angle of laser beams of 50°-60°was proposed as the optimum candidate range for the octahedral spherical hohlraums.We proposed a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields,in order to increase the laser coupling efficiency and improve the capsule symmetry and to mitigate the influence of the wall blowoff on laser transport.We studied on the sensitivity of the octahedral spherical hohlraums to random errors and compared the sensitivity among the octahedral spherical hohlraums,the rugby hohlraums and the cylindrical hohlraums,and the results show that the octahedral spherical hohlraums are robust to these random errors while the cylindrical hohlraums are the most sensitive.Up till to now,we have carried out three experiments on the spherical hohlraum with 2 LEHs on Shenguang(SG)laser facilities,including demonstration of improving laser transport by using the cylindrical LEHs in the spherical hohlraums,spherical hohlraum energetics on the SGIII prototype laser facility,and comparisons of laser plasma instabilities between the spherical hohlraums and the cylindrical hohlraums on the SGIII laser facility. | Ke Lan Jie Liu Zhichao Li Xufei Xie Wenyi Huo Yaohua Chen Guoli Ren Chunyang Zheng Dong Yang Sanwei Li Zhiwen Yang Liang Guo Shu Li Mingyu Zhang Xiaoying Han Chuanlei Zhai Lifei Hou Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Feng Wang Guanghui Yuan Haijun Zhang Bobin Jiang Lizhen Huang Wei Zhang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Xuewei Deng Dongxia Hu Wei Zhou Huaiting Jia Yongkun Ding Wanguo Zheng Xiantu He | 2016 | Matter and Radiation at Extremes2016，1，1： | 2 |
| 2 | Corrigendum to“First demonstration of improving laser propagation inside the spherical hohlraums by using the cylindrical laser entrance hole”[Matter Radiation Extremes 1(1)(2016)2-7]显示文摘Corrigendum Text:On page 2 of this letter,there is a misprint in the unit.The unit of the geometrical dimension of the spherical hohlraums on this page should always be“mm”rather than“mm”,i.e.in the second paragraph,“…with 800 J per beam at 0.35 mm…”should be“…with 800 J per beam at 0.35 mm…”,“The slit of 400 mm width is parallel…”should be“The slit of 400 mm width is parallel…”,“The laser focal diameter is about 500 mm…”should be“The laser focal diameter is about 500 mm…”;in the third paragraph,“…we take 850 mm as the radius…”should be“…we take 850 mm as the radius…”,“The LEH radius R_(L) is 400 mm…”should be“The LEH radius R_(L) is 400 mm…”,“…the radius of the cylindrical LEH outer ring is taken as 1.5 R_(L)=600 mm”should be“…the radius of the cylindrical LEH outer ring is taken as 1.5 R_(L)=600 mm”.This mistake does not affect any of the main results of the original letter. | Wenyi Huo Zhichao Li Dong Yang Ke Lan Jie Liu Guoli Ren Sanwei Li Zhiwen Yang Liang Guo Lifei Hou Xuefei Xie Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Guanghui Yuan Haijun Zhang Baibin Jiang Lizhen Huang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Yongkun Ding Xiantu He Weiyan Zhang | 2016 | Matter and Radiation at Extremes2016，1，2： | 1 |
| 3 | MyD88 exacerbates immunological pathology in experimental viral fulminant hepatitis显示文摘Objective To explore the role of MyD88 signaling in MHV-3 virus-mediated fulminant hepatitis. Methods We evaluated liver lesion status, the expression of multiple pro-inflammatory cytokines and HMGB1, the recruitment of inflammatory ILC3, and mortality in MyD88-/-and WT mice. Results The expression of multiple pro-inflammatory cytokines that recruit inflammatory ILC3 to the liver was severely impaired in MyD88-/-mice resulting in reduced liver pathology, viral replication, and mortality post-infection. Additionally, MHV-3 markedly increased the expression of high-mobility group box 1(HMGB1) in infected hepatocytes/macrophages and induced HMGB1 protein migration from the nucleus to the extracellular milieu, where it activates MyD88-dependent inflammation. Conclusion Our findings indicate that MyD88 exacerbates immunological pathology in experimental viral fulminant hepatitis. | Jianzhao Deng Qin Ning Weiming Yan Xuan Yang Lizhen Zhao Yuzhang Wu Bei Zhang | 2019 | Oncology and Translational Medicine2019，5，2： | 1 |
| 4 | Learning Dual-Domain Calibration and Distance-Driven Correlation Filter:A Probabilistic Perspective for UAV Tracking显示文摘Unmanned Aerial Vehicle(UAV)tracking has been possible because of the growth of intelligent information technology in smart cities,making it simple to gather data at any time by dynamically monitoring events,people,the environment,and other aspects in the city.The traditional filter creates a model to address the boundary effect and time filter degradation issues in UAV tracking operations.But these methods ignore the loss of data integrity terms since they are overly dependent on numerous explicit previous regularization terms.In light of the aforementioned issues,this work suggests a dual-domain Jensen-Shannon divergence correlation filter(DJSCF)model address the probability-based distance measuring issue in the event of filter degradation.The two-domain weighting matrix and JS divergence constraint are combined to lessen the impact of sample imbalance and distortion.Two new tracking models that are based on the perspectives of the actual probability filter distribution and observation probability filter distribution are proposed to translate the statistical distance in the online tracking model into response fitting.The model is roughly transformed into a linear equality constraint issue in the iterative solution,which is then solved by the alternate direction multiplier method(ADMM).The usefulness and superiority of the suggested strategy have been shown by a vast number of experimental findings. | Taiyu Yan Yuxin Cao Guoxia Xu Xiaoran Zhao Hu Zhu Lizhen Deng | 2023 | Computers, Materials & Continua2023，77，12： | 0 |
| 5 | First demonstration of improving laser propagation inside the spherical hohlraums by using the cylindrical laser entrance hole显示文摘The octahedral spherical hohlraums have natural superiority in maintaining high radiation symmetry during the entire capsule implosion process in indirect drive inertial confinement fusion.While,in contrast to the cylindrical hohlraums,the narrow space between the laser beams and the spherical hohlraum wall is usually commented.In this Letter,we address this crucial issue and report our experimental work conducted on the SGIII-prototype laser facility which unambiguously demonstrates that a simple design of cylindrical laser entrance hole(LEH)can dramatically improve the laser propagation inside the spherical hohlraums.In addition,the laser beam deflection in the hohlraum is observed for the first time in the experiments.Our 2-dimensional simulation results also verify qualitatively the advantages of the spherical hohlraums with cylindrical LEHs.Our results imply the prospect of adopting the cylindrical LEHs in future spherical ignition hohlraum design. | Wenyi Huo Zhichao Li Dong Yang Ke Lan Jie Liu Guoli Ren Sanwei Li Zhiwen Yang Liang Guo Lifei Hou Xuefei Xie Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Guanghui Yuan Haijun Zhang Baibin Jiang Lizhen Huang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Yongkun Ding Xiantu He Weiyan Zhang | 2016 | Matter and Radiation at Extremes2016，1，1： | 0 |
