Robinson Splitting Theorem and Induction

Yong Liu, Cheng Peng, Mengzhou Sun

The Robinson Splitting Theorem states that a c.e. degree splits over any low c.e. degree . We prove that a weaker version of this theorem holds…

The finite cohesiveness principle

Mengzhou Sun

We investigate the logical strength of the cohesiveness principle when restricted to finite sequences of sets, denoted by fin-COH, over different base theories. Our main result sho…

PICOs-RAG: PICO-supported Query Rewriting for Retrieval-Augmented Generation in Evidence-Based Medicine

Mengzhou Sun, Sendong Zhao, Jianyu Chen +1

Evidence-based medicine (EBM) research has always been of paramount importance. It is important to find appropriate medical theoretical support for the needs from physicians or pat…
