They occur at a crucial time in the evolution of these systems, when the accretion disc emission starts to dominate over coronal emission. Flip-flops remain a poorly understood phenomenon, so we aim to thoroughly investigate them in a system featuring several such transitions. Methods: Within the multitude of observations of Swift J1658.2-4242 during its outburst in early 2018, we detected 15 flip-flops, enabling a detailed analysis of their individual properties and the differences between them. We present observations by XMM-Newton, NuSTAR, Astrosat, Swift, Insight-HXMT, INTEGRAL, and ATCA. We analysed their light curves, searched for periodicities, computed their PDSs, and fitted their X-ray spectra, to investigate the source behaviour during flip-flop transitions and how the interval featuring flip-flops differs from the rest of the outburst. Results: The flip-flops of Swift J1658.2-4242 are of an extreme variety, exhibiting flux differences of up to 77% within 100 s, which is much larger than what has been seen previously. We observed radical changes in the PDS simultaneous with the sharp flux variations, featuring transitions between the quasi-periodic oscillation types C and A, which have never been observed before. Changes in the PDS are delayed, but more rapid than changes in the light curve. Flip-flops occur in two intervals within the outburst, separated by about two weeks in which these phenomena were not seen. Transitions between the two flip-flop states occurred at random integer multiples of a fundamental period of 2.761 ks in the first interval and 2.61 ks in the second. Spectral analysis reveals the high and low flux flip-flop states to be very similar, but distinct from intervals lacking flip-flops. A change of the inner temperature of the accretion disc is responsible for most of the flux difference in the flip-flops. We also highlight the importance of correcting for the influence of the dust scattering halo on the X-ray spectra.   The Impact of Spatial Form of Urban Architecture on the Urban Thermal Environment: A Case Study of the Zhongshan District, Dalian, China 期刊论文  OAI收割 IEEE JOURNAL OF SELECTED TOPICS IN APPLIED EARTH OBSERVATIONS AND REMOTE SENSING, 2018, 卷号: 11, 期号: 8, 页码: 2709-2716 作者:  Yang, Jun;  Su, Junru;  Xia, Jianhong (Cecilia);  Jin, Cui;  Li, Xueming   |  收藏  |  浏览/下载：36/0  |  提交时间：2019/05/23 Building height  building density  correlation analysis  heat island effect  land surface temperature (LST)  spatial and temporal evolution  Zhongshan District  Dalian   Rocket in situ observation of equatorial plasma irregularities in the region between E and F layers over Brazil 期刊论文  OAI收割 ANNALES GEOPHYSICAE, 2017, 卷号: 35, 期号: 3, 页码: 413-422 作者:  Savio Odriozola, Siomel;  de Meneses, Francisco Carlos, Jr.;  Muralikrishna, Polinaya;  Pimenta, Alexandre Alvares;  Kherani, Esfhan Alam   |  收藏  |  浏览/下载：25/0  |  提交时间：2018/02/28 Ionosphere (Equatorial Ionosphere  Plasma Temperature And Density  Plasma Waves And Instabilities)   Investigation on symmetry and characteristic properties of the fragmenting source in heavy-ion reactions through reconstructed primary isotope yields 期刊论文  OAI收割 NUCLEAR SCIENCE AND TECHNIQUES, 2016, 卷号: 27, 页码: 5 作者:  Wang, Jian-Song;  Huang, Mei-Rong;  Ren, Pei-Pei;  Wang, Qi;  Duan, Fang-Fang   |  收藏  |  浏览/下载：25/0  |  提交时间：2018/05/31 Symmetry energy  Nuclear temperature  Nuclear density and freeze-out   Investigation on symmetry and characteristic properties of the fragmenting source in heavy-ion reactions through reconstructed primary isotope yields 会议论文  OAI收割 作者:  Ren, Pei-Pei;  Duan, Fang-Fang;  Liu, Xing-Quan;  Lin, Wei-Ping;  Wada, Ryoichi   |  收藏  |  浏览/下载：41/0  |  提交时间：2018/08/20 Symmetry energy  Nuclear temperature  Nuclear density and freeze-out   Investigation on symmetry and characteristic properties of the fragmenting source in heavy-ion reactions through reconstructed primary isotope yields 会议论文  OAI收割 作者:  Jin, Shi-Lun;  Ma, Jun-Bing;  Ma, Peng;  Lin, Wei-Ping;  Wada, Ryoichi   |  收藏  |  浏览/下载：141/0  |  提交时间：2018/08/20 Symmetry energy  Nuclear temperature  Nuclear density and freeze-out   GLOBAL NONLINEAR STABILITY OF RAREFACTION WAVES FOR COMPRESSIBLE NAVIER-STOKES EQUATIONS WITH TEMPERATURE AND DENSITY DEPENDENT TRANSPORT COEFFICIENTS 期刊论文  OAI收割 KINETIC AND RELATED MODELS, 2016, 卷号: 9, 期号: 3, 页码: 469-514 作者:  Huang, Bingkang;  Wang, Lusheng;  Xiao, Qinghua 收藏  |  浏览/下载：53/0  |  提交时间：2016/07/12 One-dimensional compressible Navier-Stokes equations  temperature and density dependent transport coefficients  global nonlinear stability of rarefaction waves  large initial data   A Robust Energy/Area-Efficient Forwarded-Clock Receiver With All-Digital Clock and Data Recovery in 28-nm CMOS for High-Density Interconnects 期刊论文  OAI收割 IEEE TRANSACTIONS ON VERY LARGE SCALE INTEGRATION (VLSI) SYSTEMS, 2016, 卷号: 24, 期号: 2, 页码: 578-586 作者:  Chen, Shuai;  Li, Hao;  Chiang, Patrick Yin   |  收藏  |  浏览/下载：29/0  |  提交时间：2019/12/13 All-digital clock and data recovery (ADCDR)  delay-locked loop (DLL)  forwarded-clock (FC) receiver  high-density interconnect  jitter tolerance  multicore processor  process variation  voltage and temperature drift   Context dependency of the density-body mass relationship in litter invertebrates along an elevational gradient 期刊论文  OAI收割 SOIL BIOLOGY & BIOCHEMISTRY, 2015, 卷号: 88, 期号: 1, 页码: 323-332 作者:  Xu, Guorui;  Zhang, Shuang;  Lin, Yinghua;  Ma, Keming 收藏  |  浏览/下载：32/0  |  提交时间：2016/03/03 Density-body mass relationship  Temperature  Litter invertebrates  Litter stoichiometry  Temporal and spatial variation  Context dependency
