Summary: In this study, a continuous blood pressure (BP) monitoring method based on random forest feature selection (RFFS) and a gray wolf optimization-gradient boosting regression tree (GWO-GBRT) prediction model was developed. The method extracted features from electrocardiogram (ECG) and photoplethysmography (PPG) signals, and employed RFFS to select sensitive features highly correlated with BP. A hybrid prediction model of gray wolf optimization (GWO) technique and gradient boosting regression tree (GBRT) algorithm was established to learn the relationship between BP and sensitive features. Experimental results demonstrated the effectiveness and advancement of the proposed method.

Summary: Automatic segmentation of the placenta in MRI is challenging due to the variability of its position and shape, as well as the blurring caused by PAS. In this study, a refinement fusion based on the U-Net (RFU-Net) is proposed to address these issues and improve the segmentation accuracy. The RFU-Net utilizes ResNet34 as a feature extractor and incorporates a fusion multiscale feature (FMF) to handle the variable placental shape. A refinement segmentation module (RSM) is designed to provide information about the placental position, leading to improved segmentation results. Experimental results demonstrate the effectiveness of RFU-Net in achieving accurate placenta segmentation and highlighting potential areas of interest for diagnosis.
