+The two vertices or transition rates $\mathcal V_{\vec q\vec k}\ne\mathcal W_{\vec q\vec k}=\frac{1+\varepsilon}{2}\mathcal V_{\vec q\vec k}$ are
 unequal, different form the theory for colloidal suspensions which are in thermal equilibrium.
 This difference reflects the loss of detailed balance in the nonequilibrium granular fluid. The
