This record is the official author-maintained archive of the current version of this work by Yue Yongqiang and Yue Sifei. Earlier drafts and related preprint materials were also developed by the same authors, but were not maintained through an archival account under their direct long-term control. The present record is therefore released independently as the most complete and up-to-date version of the framework.
Yongqiang et al. (Sat,) studied this question.
