In the above paper [1], the author gives that is always greater than 0 as

where . It is observed that the denominators of (1) and
in [1] are the same and positive whereas the numerators are different. From (1), it cannot be assured that

in [1] cannot be obtained. Meanwhile, the extended proposition in [1, Section
] does not stand.
