The critical temperature $T_{\\rm c}$ and the power law exponent ($n$) of temperature-dependent resistivity ($\\rho(T) = \\rho_0 + AT^n$) show a clear correlation above $x=$0.2, suggesting that $T_{\\rm c}$ is enhanced with increasing bosonic fluctuation in the same type of FS state. Around $x=$0.2, all the transport properties show anomalies, indicating that $x$$\\sim$0.2 is the critical composition of drastic FS change.
