Before revision:  Numerical simulations, supported by analytical calculations in the linear model, show that aging leads to non-exponential length distributions in steady state , as well as oscillations in microtubule length . The oscillations are reduced and eventually eliminated by increasing the frequency of rescue events.
After revision:  Numerical simulations, supported by analytical calculations in the linear model, show that aging leads to non-exponential length distributions in steady state , as well as oscillations in microtubule length and velocity. The regularity of oscillations, as characterized by the negative dip in the autocorrelation function, is reduced by increasing the frequency of rescue events.
