Resonance-corrected equivalent load reconstruction for fatigue assessment of metro bogie frames

Qingwei Song, Chengjie Wang, 李春来, Yunpeng Wang et autres

Abstract To address the distortion of measured load signals in metro bogie frames caused by wheel-rail excitation-induced modal resonance under service conditions, field tests and signal analyses were conducted. The results show that external excitations induce modal resonance, with dominant frequencies at …

Interpretable deep learning framework based on contrast-enhanced MRI for predicting histological grade of hepatocellular carcinoma

Wenjun Hu, Xiuding Cai, Ying Zhao, Qihao Xu et autres

Background: Histopathological grading is a key prognostic marker for hepatocellular carcinoma (HCC). However, the clinical application of deep learning models (DLMs) for predicting HCC grading from medical imaging is limited by their black-box nature. We aimed to develop an interpretable DLM, interpretable …
