The result obtained by this method for the rc(T = 0) is found to be lower than static approximation result which is known from the Ising case to over-estimate the value of

On the other hand, we assume that in the elastomer state, ions substitute for monomers in the lattice cells.. They can move only if at least one of the

Here, we show that despite lentiviral infection and cell sorting, tau-GFP expressing cells retained the undifferentiated characteristics of the parental wild type LYON-ES cell line
