Text Correction

There was an error in the original publication [1]. The sign in Equation (3) and above the equation has been misprinted.

A correction has been made to 3. Results and Discussion, Paragraphs 5 and 6:

After averaging over the temperature in the transverse direction in Equation (1) and using Condition (2), we obtain

$$\frac{\partial \overline{T}}{\partial t}=\frac{\kappa }{c_p\rho }\frac{{\partial }^2\overline{T}}{\partial z^2}-\frac{2G}{R{c}_p\rho }\left(T\left(t,z,R\right)-T_{room}\right).$$

Assuming that the temperature changes across the fiber are insignificant and $\overline{T}\left(t,z\right)\approx T(t,z,R)$, which implies the relative smallness of the coefficient G, we obtain a one-dimensional equation for the temperature averaged over the transverse coordinate:

$$\frac{\partial \overline{T}}{\partial t}=\frac{\kappa }{c_p\rho }\frac{{\partial }^2\overline{T}}{\partial z^2}-\frac{2G}{R{c}_p\rho }\left(\overline{T}-T_{room}\right).$$
