The original version of this Article contained errors in the three equations reported in the Methods section entitled ‘Statistics’. The incorrect forms of the equations were:

$$Y\left( t \right) = A_1\left( {1 - e^{\frac{t}{{\tau _1}}}} \right);\,t \le \Delta t_2$$
$$Y\left( t \right) = A_1\left( {1 - e^{\frac{t}{{\tau _1}}}} \right) + A_2\left( {1 - e^{\frac{{t - \Delta t_2}}{{\tau _2}}}} \right);\,\Delta t_2 < t < \Delta t_3$$
$$Y\left( t \right) = A_1\left( {1 - e^{\frac{t}{{\tau _1}}}} \right) + A_2\left( {1 - e^{\frac{{t - \Delta t_2}}{{\tau _2}}}} \right) + A_3\left( {1 - e^{\frac{{t - \Delta t_3}}{{\tau _3}}}} \right);\,t \ge \Delta t_3$$

The correct forms of the equations are:

$$Y\left( t \right) = A_1\left( {1 - e^{ - \frac{t}{{\tau _1}}}} \right);\,t \le \Delta t_2$$
$$Y\left( t \right) = A_1\left( {1 - e^{ - \frac{t}{{\tau _1}}}} \right) + A_2\left( {1 - e^{ - \frac{{t - \Delta t_2}}{{\tau _2}}}} \right);\,\Delta t_2 < t < \Delta t_3$$
$$Y\left( t \right) = A_1\left( {1 - e^{ - \frac{t}{{\tau _1}}}} \right) + A_2\left( {1 - e^{ - \frac{{t - \Delta t_2}}{{\tau _2}}}} \right) + A_3\left( {1 - e^{ - \frac{{t - \Delta t_3}}{{\tau _3}}}} \right);\,t \ge \Delta t_3$$

These errors have been corrected in both the PDF and HTML versions of the article.
