A new mechanical structural damage feature index based on HHT [PDF]
, 2018 A new damage feature index is presented for the structural health monitoring based on Hilbert-Huang transform (HHT). The energy marginal spectrum of the dynamic signal is used to construct damage characteristic parameter, which can reflect the signal ...

Revealing the Link between Structural Relaxation and Dynamic Heterogeneity in Glass-Forming Liquids
, 2018 Despite the use of glasses for thousands of years, the nature of the glass transition is still mysterious. On approaching the glass transition, the growth of dynamic heterogeneity has long been thought to play a key role in explaining the abrupt slowdown

Dynamic and static angry faces influence time perception differently—Evidence from ERPs
Frontiers in Neuroscience, 2023 The dynamic characteristics of facial expressions might affect time perception. Compared with static emotional faces, dynamic emotional faces are more intense, have higher ecological validity, and contain time series information, which may lead to time ...
