  Motivated by several conjectures posed in the paper "F. Qi and A.-Q. Liu,
Completely monotonic degrees for a difference between the logarithmic and psi
functions, J. Comput. Appl. Math., vol. 361, pp. 366--371 (2019); available
online at https://doi.org/10.1016/j.cam.2019.05.001", the authors compute
several completely monotonic degrees of the remainders in the asymptotic
expansions of the logarithm of the gamma function and in the asymptotic
expansions of the logarithm of the digamma function.
