Non-local modulation of the energy cascade in broad-band forced turbulence [PDF]

open access: yes, 2006
Classically, large-scale forced turbulence is characterized by a transfer of energy from large to small scales via nonlinear interactions. We have investigated the changes in this energy transfer process in broad-band forced turbulence where an ...

Modulation transfer functions for audiovisual speech

open access: yesPLOS Computational Biology, 2022
Temporal synchrony between facial motion and acoustic modulations is a hallmark feature of audiovisual speech. The moving face and mouth during natural speech is known to be correlated with low-frequency acoustic envelope fluctuations (below 10 Hz), but the precise rates at which envelope information is synchronized with motion in different parts of ...
