Simultaneous Drift Calibration and Reconstruction for Scanning-Probe X-Ray Tomography
Xiang Huang, Parth Brahmbhatt, Chang Meng +1
Scanning-probe x-ray tomography is useful for imaging nanoscale structures of a sample. The image resolution, which can reach down to 10 nm by the increased brightness and coherenc…
Cross-View Attention Fusion Net: A Prior-Guided Dual-View Representation Learning for Cardiac Output Estimation from Short-Term PPG Signals
Yaowen Zhang, Bo Cui, Libera Fresiello +3
Accurate cardiac output (CO) estimation from photoplethysmography (PPG) is promising for unobtrusive hemodynamic monitoring, but remains difficult since CO is jointly determined by…
Compact Latent Manifold Translation: A Parameter-Efficient Foundation Model for Cross-Modal and Cross-Frequency Physiological Signal Synthesis
Bo Cui, Xiaowen Song, Yaowen Zhang +4
The analysis of physiological time series, such as electrocardiograms (ECG) and photoplethysmograms (PPG), is persistently hindered by modality and frequency gaps stemming from het…
Evaluating Multi-Sensor Placement and Neural Network Architectures for Physical Activity Level Classification
Bo Cui, Xiaowen Song, Tabak Monique +2
Accurate physical activity level (PAL) classification could be beneficial for osteoarthritis (OA) management. This study examines the impact of sensor placement and deep learning m…
