Characterising hydrothermal fluid pathways beneath Aluto volcano, Main Ethiopian Rift, using shear wave splitting

, 2018
Geothermal resources are frequently associated with silicic calderas which show evidence of geologically-recent activity. Hence development of geothermal sites requires both an understanding of the hydrothermal system of these volcanoes, as well as the ...

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Upper Mantle Anisotropy and Flow Beneath the Pacific Ocean Revealed by Differential PS‐SKS Splitting

Geophysical Research Letters, 2023
Upper mantle anisotropy has been mapped beneath continents at high spatial resolution. Beneath the oceans, however, shear wave splitting constraints on upper mantle anisotropy are sparse, due to the paucity of seismic receivers. A technique that does not

Printable Liquid Metal‐Textiles for Deformation‐Insensitive and Electromagnetically Robust mmWave Devices

Advanced Science, EarlyView.
We present a textile‐compatible, self‐healing liquid metal ink and a dual‐mask printing technique for high‐resolution patterning. Using this approach, we demonstrate high‐performance millimeter‐wave (mmWave) electronic textiles that exhibit exceptional insensitivity to deformation.

Mantle Structure and Flow Across the Continent‐Ocean Transition of the Eastern North American Margin: Anisotropic S‐Wave Tomography

Geochemistry, Geophysics, Geosystems, 2021
Little has been seismically imaged through the lithosphere and mantle at rifted margins across the continent‐ocean transition. A 2014–2015 community seismic experiment deployed broadband seismic instruments across the shoreline of the eastern North ...

Cosmic Electromagnetic Fields due to Perturbations in the Gravitational Field [PDF]

, 2012
We use non-linear gauge-invariant perturbation theory to study the interaction of an inflation produced seed magnetic field with density and gravitational wave perturbations in an almost Friedmann-Lema\^itre-Robertson-Walker (FLRW) spacetime.

Crustal anisotropy and state of stress at Uturuncu Volcano, Bolivia, from shear-wave splitting measurements and magnitude–frequency distributions in seismicity

, 2018
The physical signatures of unrest in large silicic magma systems are commonly observed in geophysical surveys, yet the interactions between magmatic processes and crustal stresses are often left unconstrained.

Charge‐Acoustic Phonon Coupling Determined Carrier Transport Properties in FAxMA1−xPbBr3 Perovskite Single Crystals

Advanced Science, EarlyView.
This study investigates acoustic phonon‑carrier coupling in FAxMA1−xPbBr3 single crystals using time‑domain Brillouin scattering. The results show that increasing the FA content in FAxMA1−xPbBr3 single crystal reduces both the elastic constant and the intrinsic carrier mobility governed by the acoustic phonon‑carrier coupling.

Prediction of Complex Observed Shear Wave Splitting Patterns at Ryukyu Subduction Zone Using a Strong Intra‐Slab Anisotropy Model

Geophysical Research Letters
Complex shear wave splitting (SWS) patterns in subduction zones are often interpreted geodynamically as resulting from complex mantle flow; however, this may not always be necessary.

Azimuthal anisotropy beneath north central Africa from shear wave splitting analyses

Geochemistry, Geophysics, Geosystems, 2015
This study represents the first multistation investigation of azimuthal anisotropy beneath the interior of north central Africa, including Libya and adjacent regions, using shear wave splitting (SWS) analysis.
