From the article:

This principle is fundamentally different from the effect of dimples on golf balls. Dimples reduce pressure resistance by intentionally turbulizing the airflow and suppressing backward separation. DMR, on the other hand, delays the transition [to turbulent boundary layer flow], thereby suppressing not pressure resistance but the wall friction itself. They are opposite mechanisms.
