Summary: We also explore the thermodynamic behavior of the one-component liquid via the inherent structure formalism to study the connection between the dynamical strings and clusters we have investigated and the "cooperatively rearranging region (CRR)" of the Adam-Gibbs (AG) theory. We find that the average cluster size is linearly related to the inverse of the configurational entropy Sconf, as observed in simulated water. However, we also find a similar linear relationship between the average string size and configurational entropy.
