Recently, we noticed Figs. 4 and 5 were interchanged in Ref. 1, although their respective captions remain correct (Figs. 1 and 2). A typing mistake in mathematical signs is also found on page 12. We submit this erratum to correct the result.
The correct Figs. 4 and 5 are given below with respective captions.
This line on page 12 with the correct mathematical sign should be
“Also in the case of , , as , and the condition is obvious as the sign of is opposite ( ) to which makes more negative.”
