Web18 jan. 2024 · The hyperbolastic functions, also known as hyperbolastic growth models, are mathematical functions that are used in medical statistical modeling. These models were originally developed to capture the growth dynamics of multicellular tumor spheres, and were introduced in 2005 by Mohammad Tabatabai, David Williams,...
Web1 okt. 2014 · Growth models have been used to describe such changing behaviors. Some of the most predominantly used growth models are the Logistic, Gompertz, and Weibull growth models. The logistic curve is symmetric with equal period of slow and fast growth while the Gompertz curve is asymmetric with a shorter period of fast growth ( Tabatabai … WebResults. By measuring stress-bearing linear deformations (caused by differences in cell movement rates) in the outer cell layer of blastula – early tail-bud Xenopus embryos, we revealed a set of long-term tension-generating gradients of cell movement rates, modulated by short-term cell-cell displacements much increasing the rates of local deformations.
