# s-gst: lastly, they indicate the generality of that

<< Lastly, [AA] indicate the generality of this phenomenon by demonstrating suppression of chaotic oscillations by coupling to a common hyper-chaotic system. These results then indicate the easy controllability of chaotic oscillators by an external chaotic system, thereby suggesting a potent method that may help design control strategies. >>

<< Some in the scientific community view null results research as a failure because, by its very definition, a null result means what you expected would happen in your study did not happen. >>
