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

Generalization of 3D Mandelbrot and Julia sets
In order to further enrich the form of 3D Mandelbrot and Julia sets, this paper first presents two methods of generating 3D fractal sets by utilizing discrete modifications of the standard quaternionExpand

Isogeometric analysis of large thin shell structures based on weak coupling of substructures with unstructured T-splines patches
A new isogeometric analysis method is proposed for large thin shell structures based on the weak coupling of substructures with unstructured T-splines patches. Expand

NaI Doping Effect on Photophysical Properties of Organic-Lead-Halide Perovskite Thin Films by Using Solution Process
Perovskite solar cells (PSCs) have been developed rapidly in recent years. How to modify the photophysical properties of perovskite films has become the critical issue, affecting device performance.Expand

[Wavelet application to reduction of stimulus artifact in transient evoked otoacoustic emissions testing].
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
