We detect optical Quasi-Periodic Oscillations (QPOs) that move to higher frequencies as the outburst progresses, tracking both the frequency and evolution of similar X-ray QPOs previously reported. Correlated X-ray/optical data reveal a complex pattern of lags, including an anti-correlation and a sub-second lag that evolve over the first few weeks of outburst. They also show correlated components separated by a lag equal to the QPO period roughly centered on zero lag, implying that the inter-band variability is strongly and consistently affected by these QPOs at a constant phase lag of roughly ±Ю The synchronisation of X-ray and optical QPOs indicates that they must be produced in regions physically very close to each other  we thus propose that they can be explained by a precessing jet model, based on analogies with V404 Cyg and MAXI J1348-630.   A GPU-based phase tracking method for planetary radio science applications 期刊论文  OAI收割 MEASUREMENT SCIENCE AND TECHNOLOGY, 2020, 卷号: 31, 期号: 4, 页码: 15 作者:  Jian, Nianchuan;  Mikushin, Dmitry;  Yan, Jianguo;  Barriot, Jean-Pierre;  Wu, Yajun   |  收藏  |  浏览/下载：44/0  |  提交时间：2021/12/06 phase tracking  Doppler dataprocessing  radiosciences  GPU  CUDA   Combined carrier phase and code phase passive radiation source localisation method 期刊论文  OAI收割 IET RADAR SONAR AND NAVIGATION, 2020, 卷号: 14, 期号: 1, 页码: 147-155 作者:  Li, Youyang;  Wang, Xue;  Lu, Xiaochun   |  收藏  |  浏览/下载：26/0  |  提交时间：2020/11/09 Kalman filters  position control  direction-of-arrival estimation  Global Positioning System  nonlinear filters  time-of-arrival estimation  code phase passive radiation source localisation method  high-precision positioning method  arrival methods  carrier phase-based  positioning process  position tracking  times higher accuracy  TDOA method  positioning accuracy  traditional positioning method  combined carrier phase  time 4  0 s to 10  0 s   Time and frequency transfer using BDS-2 and BDS-3 carrier-phase observations 期刊论文  OAI收割 IET RADAR SONAR AND NAVIGATION, 2019, 卷号: 13, 期号: 8, 页码: 1249-1255 作者:  Zhang, Pengfei;  Tu, Rui;  Zhang, Rui;  Liu, Na;  Gao, Yuping   |  收藏  |  浏览/下载：30/0  |  提交时间：2021/11/29 clocks  Global Positioning System  geodesy  atomic clocks  time transfer  geodetic distance time links  time dilution  averaging time intervals  BDS-3 solution  HOB2-KAT1 time link  satellite tracking geometry  CEDU-KAT1 time link  BDS-2 constellation  BDS-2 satellites  global satellite navigation system  current regional BDS-2  BDS-3e  third-generation BeiDou navigation satellite system  BDS-3 carrier-phase observations  frequency transfer   A quantitative phase-field model combining with front-tracking method for polycrystalline solidification of alloys 期刊论文  OAI收割 COMPUTATIONAL MATERIALS SCIENCE, 2015, 卷号: 104, 页码: 155-161 Chen, Yun; Qi, Xin Bo; Li, Dian Zhong; Kang, Xiu Hong; Xiao, Na Min 收藏  |  浏览/下载：45/0  |  提交时间：2016/04/21 Phase-field  Front-tracking  Polycrystalline growth  Alloy  Solidification   Application of Combined Controller Based on CMAC and Nonlinear PID in Dual Redundant Telescope Tracking System 会议论文  OAI收割 Montréal, Quebec, Canada, 2014-6-22 作者:  Wujun;  RenChangzhi;  LiHeng 收藏  |  浏览/下载：30/0  |  提交时间：2015/03/12 direct drive  Nonlinear – PID  CMAC  Dual Redundant Telescope Tracking System  Dual-redundant six phase direct drive motors   InSAR相位重建技术与PSInSAR地表形变监测技术研究 学位论文  OAI收割 博士, 北京: 中国科学院研究生院, 2014 陈润璞 收藏  |  浏览/下载：42/0  |  提交时间：2014/06/10 合成孔径雷达干涉技术(InSAR)  永久散射体干涉技术(Persistent Scatterer Interferometry  非局部(Nonlocal  相位解缠(Phase Unwrapping  差分合成孔径雷达干涉技术(DInSAR)  PSInSAR)  NL)滤波  PhU)  STAMPS  相位降噪  相位重建  模型误差  EMD算法  Offset-tracking算法   A new synchronization control method of wafer and reticle stage in step and scan lithographic equipment 期刊论文  OAI收割 OPTIK, 2013, 卷号: 124, 期号: 24, 页码: 6861-6865 作者:  Li, Lanlan;  Hu, Song;  Zhao, Lixin;  Ma, Ping;  Li, Jinlong 收藏  |  浏览/下载：47/0  |  提交时间：2015/04/17 Scanner  Synchronization error  Tracking error  Phase difference
