WebThe shear-thinning liquid drop model assumes that the cytoplasm of a cell acts as non-Newtonian fluid. This model accounts for changes in cytoplasmic viscosity with applied shear rates. Specifically, there is a decrease in cytoplasm viscosity with increasing aspiration pressure, that is, shear rate (Needham and Hochmuth, 1990; Tsai et al., 1993 ... WebFeb 3, 2024 · Overall, our data were more consistent with heterogeneity in cytoplasm viscosity (Fig. 4) than a two-state system of mobile and immobile particles. In the Doppelgänger simulations with heterogeneous viscosity, nonergodicity arises from the fact that particles within distinct spatial domains exhibit different diffusion rates. songsterr hallowed be thy name https://thepowerof3enterprises.com
