The predicted MR by the Cubic model vs. the actual MR at five temperatures (A); the relationship between effective ln \({{\varvec{D}}}_{{\varvec{e}}{\varvec{f}}{\varvec{f}}}\) and temperature (B). The predicted MR by the Cubic model vs. the actual MR at different temperatures (C₁:35 ℃; C₂:45 ℃; C₃:55 ℃; C₄:65 ℃; C₅:75 ℃).
