Abstract Background Partial restoration combined with periodontal root coverage surgery can be applied to the treatment of non-carious cervical lesions (NCCLs) accompanied with gingival recessions in clinical practice.However, the feasibility of NCCL partial restorative treatment from a biomechanical perspective remains unclear.This study aimed to
ObjectiveIn response to challenges such as large sampling data, extended diagnosis time, and subjective fault feature selection in traditional bearing fault diagnosis, a CS-DMKELM intelligent diagnosis model for rolling bearings is proposed based on compressed sensing(CS) kuiper belt whiskey and deep multi-kernel extreme learning machine(D-MKELM) t
