A new near‐infrared fluorescence sensor PDI‐PD for Ag+ ions was successfully prepared and its structure characterized by 1H nuclear magnetic resonance (NMR), 13C NMR and high‐resolution mass spectrometry; matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (HRMS MALDI‐TOF). The probe exhibited rapid, sensitive, and selective two‐channel fluorescence responses towards Ag+ ions...
Purpose:To recover speech corrupted by functional magnetic resonance imaging (fMRI) acoustic noise using two‐channel adaptive speech enhancement techniques.
Materials and Methods:Speech corrupted by noise generated from a 3 T MRI scanner was recorded using diffuse‐field microphones and a data acquisition board. Multiband and subband adaptive speech enhancement methods are used to recover the speech...
