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 ...
