Query: Scaling Behavior and Variable Hopping Conductivity in the Quantum Hall
  Plateau Transition   We have measured the temperature dependence of the longitudinal resistivity
$% \rho_{xx}$ of a two-dimensional electron system in the regime of the quantum
Hall plateau transition. We extracted the quantitative form of scaling function
for $\rho_{xx}$ and compared it with the results of ordinary scaling theory and
variable range hopping based theory. We find that the two alternative
theoretically proposed scaling functions are valid in different regions.
