The q -polarized insertion mode. A receptor insertion paradigm denoted here by means of S ^rθ(0, 0, q, m, α) is linked to the case $S_c^{\mathit{r\theta }}\left(m,\alpha \right)=0$, $S_p^{\mathit{r\theta }}\left(m,\alpha \right)=0$, and $S_q^{\mathit{r\theta }}\left(m,\alpha \right)=q$, with q a positive constant. This mode is non-radially symmetric and polarized. Setting = π , the q-polarized insertion mode gives the paradigm of Wofsy et al. [35] for insertion in plaques. Even when λ = v ₁/2D ₀ holds so that the capping phenomenon could create a graduated distribution of unbound receptors in the direction of flow streamlines, this mode seems to provide a highly efficient form of receptor insertion by making dramatic reductions on τ _du .
