Query: Thrust Distribution in Electron-Positron Annihilation using the
  Principle of Maximum Conformality   We present a comprehensive and self-consistent analysis for the thrust
distribution by using the Principle of Maximum Conformality (PMC). By absorbing
all nonconformal terms into the running coupling using PMC via renormalization
group equation, the scale in the running coupling shows the correct physical
behavior and the correct number of active flavors is determined. The resulting
PMC predictions agree with the precise measurements for both the thrust
differential distributions and the thrust mean values. Moreover, we provide a
new remarkable way to determine the running of the coupling constant
$\alpha_s(Q^2)$ from the measurement of the jet distributions in
electron-positron annihilation at a single given value of the center-of-mass
energy $\sqrt{s}$.
