Before revision:  Our model turns out to be  analytically solvable, which enables a direct comparison of its predictions with  empirical counterparts, for instance, with so significant and commonly used quantity as a velocity autocorrelation function.
After revision:  Our model turns out to be exactly analytically solvable, which enables a direct comparison of its predictions with empirical counterparts, for instance, with so significant and commonly used quantity as a velocity autocorrelation function.
