    From DNA Radiation Damage to Cell Death: Theoretical Approaches by Francesca Ballarini

    Published 2010-01-01
    “…Furthermore, a mechanistic model developed at the University of Pavia and based on the relationship between cell inactivation and chromosome aberrations was presented, together with recent results; the good agreement between model predictions and literature experimental data on different radiation types (photons, protons, alpha particles, and Carbon ions) supported the idea that asymmetric chromosome aberrations like dicentrics and rings play a fundamental role for cell death. …”

    Collider and CMB complementarity of leptophilic dark matter with light Dirac neutrinos by Debasish Borah, Nayan Das, Sahabub Jahedi, Bhavya Thacker

    Published 2025-01-01
    “…Considering DM relic to be generated via the thermal freeze-out, we check the discovery prospects at future lepton colliders via mono-photon plus missing energy searches. The right chiral parts of light Dirac neutrinos get thermalised due to their interactions with the bath as well as leptophilic DM, leading to enhanced effective relativistic degrees of freedom N eff within reach of future cosmic microwave background (CMB) experiments. …”

    A New Interpretation for the Hot Corona in Active Galactic Nuclei by Yu Zhao, Yan-Rong Li, Jian-Min Wang

    Published 2025-01-01
    “…Within this reconnection layer, the tearing instability leads to the formation of a chain of plasmoids, which contain relativistic electrons that generate X-ray radiation through inverse-Compton (IC) scattering of soft photons emitted by the accretion disk. Based on previous theoretical works and numerical simulations, we develop a heuristic framework to parameterize the geometry and magnetization of the reconnection layer, as well as to compute both the power of the IC-scattering radiation and the height of the reconnection layer. …”
