Chirality may arise in a supramolecular system if one of its component is chiral or if achiral components arrange in a non symmetrical way to produce a supermolecule that is chiral.
2.
The rear shock / spring is directly connected, without linkages, to a non symmetrical, gull wing, aluminum swing arm instead of the more basic steel swing arm used on the Ninja and ER-6.
3.
If the test statistic is less ( this test is non symmetrical so we do not consider an absolute value ) than the ( larger negative ) critical value, then the null hypothesis of \ gamma = 0 is rejected and no unit root is present.
