    Computational modelling of γ-H2AX foci formation in human cells induced by alpha particle exposure by Ali Abu Shqair, Ui-Seob Lee, Eun-Hee Kim

    Published 2022-08-01
    “…The correction factor for foci number was calculated using the foci overlapping ratio and foci size distribution, which are specific to dose from alpha particle exposure. The number of individual foci formations induced by applying the correction factor to the experimentally observed number of focal images better reflected the quality of alpha particles in causing DNA damage. …”

    Kinetic Features of Alpha Particles in a Pestchek-like Magnetic Reconnection Event in the Solar Wind Observed by Solar Orbiter by Die Duan, Jiansen He, Xingyu Zhu, Rui Zhuo, Ziqi Wu, Georgios Nicolaou, Jia Huang, Daniel Verscharen, Liu Yang, Christopher J. Owen, Andrey Fedorov, Philippe Louarn, Timothy S. Horbury

    Published 2023-01-01
    “…We find a two-population distribution of the alpha particles. These two populations are field aligned downstream the SSs and shift to have a perpendicular offset in the reconnection jet, suggesting that the change of the magnetic field at the RDs has similar timescales with the proton gyroperiod, but faster than those of the alpha particles, such that the alpha particles behave like pickup ions.…”
