All Figures in Two Articles by LIU Yueliang (刘月亮) Are Identical and Derived from a Single Master's Thesis


An investigation conducted by the 5GH Team has revealed that two articles, [1] and [2], contain 20 identical figures, all of which are reused from the Master's Thesis of LIU Wenbin, a former student at China University of Petroleum (East China).

Every figure in Article [1] matches the corresponding figure in Article [2] exactly. Furthermore, all 20 figures are directly reproduced from LIU Wenbin's Master's Thesis.

In addition to the reused figures across both articles, the investigation also identified that multiple passages in Article [1] were paraphrased from Article [2].

Examples of the reused figures and paraphrased passages are provided below:

Articles [1] and [2] share only one common author: LIU Yueliang (刘月亮), affiliated with China University of Petroleum (Beijing). Notably, LIU Wenbin acknowledged in his Master's Thesis that he was supervised by HOU Jian and LIU Yueliang, stating: "本论文是在侯健老师和刘月亮老师的悉心指导下完成的" (This thesis was completed under the careful guidance of Professor HOU Jian and Professor LIU Yueliang). These findings indicate that LIU Yueliang bears primary responsibility for this case of figure/data reuse and text paraphrasing.
