H2‐YOLO: An Efficient CNN‐Transformer Hybrid Detector for Pulmonary Nodule Detection

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper proposes an efficient CNNâ€″Transformer hybrid detector, termed HÂ2‐YOLO, designed to address the challenge of balancing accuracy and real‐time performance in pulmonary nodule detection. By systematically reconstructing the backbone, neck, and detection head, we integrate multiple advanced mechanisms, including lightweight hybrid feature ...

Heart Rate Variability Response to Therapist‐Selected Music as a Diagnostic Biomarker for Disorders of Consciousness

Sensory Neuroscience, Volume 1, Issue 3, December 2025.
Music modulates autonomic pathways to alter heart rate variability (HRV), with therapist‐selected music (TSM) showing the strongest association with consciousness levels in patients with disorders of consciousness (DOC). ABSTRACT Music, as an auditory stimulus, has long been recognized for its ability to evoke heart rate variability (HRV) responses. In

A Flow Hydrograph Estimation Method Based on Sediment‐Water Relationship in Channelized Debris Floods

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Debris flood, a major hazard in mountainous areas, is characterized as a mixture of water and sediment primarily driven by hydrological processes. However, the relationship between water and sediment remains unclear, and accurately describing the hydrograph of such flows continues to pose significant challenges due to the complexity of the ...

Rolling bearing fault diagnosis based on RQA with STD and WOA-SVM

Heliyon
A rolling bearing fault diagnosis method based on Recursive Quantitative Analysis (RQA) combined with time domain feature extraction and Whale Optimization Algorithm Support Vector Machine (WOA-SVM) is proposed. Firstly, the recurrence graph of the vibration signal is drawn, and the nonlinear feature parameters in the recurrence graph combined with ...
