The CFPD-HCD model validations: (a-b) Droplet dynamics validation at different molality (m), RH, and T (El Golli et al., 1977); (c) The validation of dry NaCl particle hygroscopic growth at different RH and T; (d) In-house HCD modeling results of the concentration time courses for the targeted cell, infected cell, and refractory cell; (e) Comparisons of the mean viral titer [TCID₅₀ ml⁻¹] for the HCD model validation; and (f) Comparisons of the IFN data in early studies Fritz et al. (1999); Hayden et al. (1998, 1996).
