The masking-level difference in low-noise noise.

open access: yesThe Journal of the Acoustical Society of America, 1996
The masking-level difference for a 500-Hz pure tone signal was examined for an interaurally in-phase noise having different degrees of power fluctuations. MLDs were reliably smaller in noise having relatively low power fluctuations. This effect was due to the following trends in the threshold data. (1) For all subjects, the So threshold improved as the

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
