Separation of Body and Surface Wave Background Noise and Passive Seismic Interferometry Based on Synchrosqueezed Continuous Wavelet Transform

Applied Sciences
Passive seismic interferometry is a technique that reconstructs virtual seismic records using ambient noise, such as random noise or microseisms. The ambient noise in passive seismic data contains rich information, with surface waves being useful for the

Inversion for Anisotropic Velocity Parameter [PDF]

, 1997
The problem under study concerns the robust computation of a certain parameter of anisotropy from observed travel-times of a seismic shear wave propagating through a geological medium. We have obtained an exact mathematical description of a geoseismic

In Situ Growth of 2D Perovskite Nanocrystals to Induce β–Phase of PVDF for Piezoelectric Nanogenerators with Ultra‐High Output Voltage

Small, EarlyView.
In situ grown 2D perovskite nanocrystals embedded in PVDF enable flexible piezoelectric nanogenerators with greatly enhanced β‐phase content and a high d33∗${\mathrm{d}}_{33}^{\mathrm{*}}$ of 35.16 pm/V. The devices deliver up to 66.54 V, exhibit light‐enhanced piezoelectricity, and maintain durability over 12000 cycles, offering a stable energy source

The Pier Luigi Nervi's concrete structure of Palazzetto dello Sport: Modeling and dynamic characterization

Structural Concrete, EarlyView.
Abstract This paper presents a numerical and experimental study aimed at the modeling and dynamic characterization of the reinforced concrete structure of the Palazzetto dello Sport in Rome, designed and by Pier Luigi Nervi with Annibale Vitellozzi, and built by Nervi & Bartoli contractors in 1956‐57.

Fe alloy slurry and a compacting cumulate pile across Earth's inner-core boundary

, 2019
Seismic observations show a reduced compressional-wave gradient at the base of the outer core relative to the preliminary reference Earth model and seismic wave asymmetry between the east-west hemispheres at the top of the inner core.
