## Description

- description: 'Dynamics in liquids and glasses can be assessed using X-ray photon
    correlation spectroscopy or electron correlation microscopy, which involves measuring
    the temporal changes in diffraction patterns. Two methods are commonly used to
    evaluate these temporal changes: one-time correlation function or two-time correlation
    function. However, the specific characteristics of these methods have not been
    thoroughly studied. In this study, we investigated the differences between these
    methods and found that the two-time correlation function can measure dynamics
    for longer periods than the method relying on the one-time correlation function.
    Additionally, we demonstrated that the two-time correlation function exhibits
    a weak dependence on the amount of dose applied.'
