Two new tirucallane triterpenoids from the leaves of Aquilaria sinensis
Two new tirucallane triterpenoids, aquilacallanes A–B (1–2), together with 15 known compounds (3–17) were isolated from the leaves of Aquilaria sinensis. The structures of these new compounds wereExpand

[The time-frequency analysis of the heart sound].
The Wigner-Ville distribution, the Choi-Williams distribution, and cone-kernel distribution are three time-frequency distributions. We compared the interference attenuation and time-frequencyExpand

Uniqueness of determining the variable fractional order in variable-order time-fractional diffusion equations.
We study an initial-boundary value problem of variable-order time-fractional diffusion equations in one space dimension. Based on the wellposedness of the proposed model and the smoothing propertiesExpand

[Wavelet application to reduction of stimulus artifact in transient evoked otoacoustic emissions testing].
TLDR
We propose an artifact reduction technique based on discrete wavelet transform pre-processing method and demonstrate empirically that the method not only improves artifact reduction but also enhances signal-to-noise ratio in the response region. Expand
