Typology of Luxury Brand-Art Collaborations,at are directly related to physical parameters as surface to volume ratio, curvature and surface relaxivity. In particular, it is shown that the short observation time expansion of the diffusion propagator resolves the surface to volume ratio from the surface relaxivity. Comments for the diffusion propagator at longer time scales are also given.作者: tooth-decay 時間: 2025-3-23 07:04 作者: 南極 時間: 2025-3-23 12:12
