In this study, we present the investigation of nonstationary QPPs with multiple periods during the impulsive phase of a powerful flare on 2017 September 6, which were simultaneously measured by the Hard X-ray Modulation Telescope (Insight-HXMT), as well as the ground-based BLENSW. The multiple periods, detected by applying a wavelet transform and Lomb-Scargle periodogram to the detrended light curves, are found to be ~20-55 s in the Ly`and mid-ultraviolet Balmer continuum emissions during the flare impulsive phase. Similar QPPs with multiple periods are also found in the hard X-ray emission and low-frequency radio emission. Our observations suggest that the flare QPPs could be related to nonthermal electrons accelerated by the repeated energy release process, i.e., triggering of repetitive magnetic reconnection, while the multiple periods might be modulated by the sausage oscillation of hot plasma loops. For the multiperiodic pulsations, other generation mechanisms could not be completely ruled out.   A low-dissipation solver based on openFOAM designed for large eddy simulation in compressible flow 会议论文  OAI收割 Xiamen, China, March 6, 2017 - March 9, 2017 作者:  Lee YC;  Yao W(姚卫);  Fan XJ(范学军)   |  收藏  |  浏览/下载：52/0  |  提交时间：2018/11/08 Computational Fluid Dynamics  Digital Storage  Kinetic Energy  Kinetics  Open Source Software  Open Systems  Ramjet Engines  Runge Kutta Methods  Shock Tubes  Turbulence  Two Phase Flow  Bench  Mark Problems  Central  Upwind Scheme  Computational Fluid Dynamics Software  Skew  Symmetric Forms  Temporal Discretization  Turbulence Structures  Unstructured Meshes  Wall Bounded Turbulence   Cumulative latency advance underlies fast visual processing in desynchronized brain state 期刊论文  OAI收割 PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 2014, 卷号: 111, 期号: 1, 页码: 515-520 Wang, XD; Chen, C; Zhang, DH; Yao, HS 收藏  |  浏览/下载：23/0  |  提交时间：2014/07/30 NEURONS IN-VIVO  NEOCORTICAL NEURONS  SIMPLE CELLS  SPATIAL-FREQUENCY  AUDITORY-CORTEX  CEREBRAL-CORTEX  TEMPORAL PHASE  BARREL CORTEX  REACTION TIME  DYNAMICS   The mass transfer process and the growth rate of NaCl crystal growth by evaporation based on temporal phase evaluation 期刊论文  OAI收割 OPTICS AND LASERS IN ENGINEERING, 2012, 卷号: 50, 期号: 4, 页码: 540-546 作者:  Zhao J;  Miao H;  Duan L(段俐);  Kang Q(康琦);  He LH 收藏  |  浏览/下载：27/0  |  提交时间：2013/01/18 Interferometry  Temporal phase evaluation  Mass transfer  Crystal growth rate  Vibration Measurement  Shift Interferometer  Concentration Field  Fourier-Transform  Crystallization  Deformation  Microscopy  Sequence  Patterns  Kinetics   The structural stabilities of Al(3)(Sc(1-x)M(x)) by first-principles calculations 期刊论文  OAI收割 Computational Materials Science, 2011, 卷号: 50, 期号: 7, 页码: 2162-2166 H.
