A shear wave analysis system for semi-automatic measurements of shear wave splitting above volcanic earthquakes: descriptions and applications

, 2007
Our interest is the study of the seismograms with the purpose of monitoring and modelling volcanoes. In particular, since the shear waves bring information about the anisotropic system characterizing the shallow crust, they are also sensitive to all ...

Crust-mantle decoupling revealed by seismic velocity anisotropy beneath Syowa Station, Antarctica

Antarctic Record, 1997
We analyzed shear wave splittings in the crust beneath Syowa Station, using Moho converted Ps waves. Three set of receiver functions and stacked receiver functions from Tonga events are analyzed.

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride

Advanced Functional Materials, EarlyView.
Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Small Shear Wave Splitting Delays Suggest Weak Anisotropy in Cratonic Mantle Lithosphere

Geophysical Research Letters, 2021
We use splitting in core‐refracted teleseismic shear waves (SKS, PKS, and similar) to investigate anisotropic properties of the upper mantle beneath the Superior craton in eastern North America and the Yilgarn craton in Western Australia.

Defect‐Templated Phase Engineering in Atomically Thin Metals

Advanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Sub‐slab anisotropy beneath the Sumatra and circum‐Pacific subduction zones from source‐side shear wave splitting observations

Geochemistry, Geophysics, Geosystems, 2014
Understanding the dynamics of subduction is critical to our overall understanding of plate tectonics and the solid Earth system. Observations of seismic anisotropy can yield constraints on deformation patterns in the mantle surrounding subducting slabs ...

Classification of Teleseismic Shear Wave Splitting Measurements: A Convolutional Neural Network Approach

Geophysical Research Letters, 2022
Shear wave splitting (SWS) analysis is widely used to provide critical constraints on crustal and mantle structure and dynamic models. In order to obtain reliable splitting measurements, an essential step is to visually verify all the measurements to ...

Percolation‐Driven β‐Relaxation Enables Resonant Acceleration of Crystallization in Amorphous Phase‐Change Materials

Advanced Materials, EarlyView.
Mobile‐atom percolation underlying β‐relaxations fundamentally dictates the crystallization pathways of phase‐change materials. High‐frequency ultrasonic excitation dynamically modulates this critical mobility percolation network, substantially accelerating the crystallization process.
