Mode-coupling approach to non-Newtonian Hele-Shaw flow

, 2002
The Saffman-Taylor viscous fingering problem is investigated for the displacement of a non-Newtonian fluid by a Newtonian one in a radial Hele-Shaw cell.

Covariant Perturbations of Schwarzschild Black Holes [PDF]

, 2002
We present a new covariant and gauge-invariant perturbation formalism for dealing with spacetimes having spherical symmetry (or some preferred spatial direction) in the background, and apply it to the case of gravitational wave propagation in a ...

Reply to "Comment on 'Operational Earthquake Forecasting: Status of Knowledge and Guidelines for Implementation by Jordan et al. [2011]' by Stuart Crampin"

Annals of Geophysics, 2012
In his commentary on the International Commission on Earthquake Forecasting (ICEF) report [Jordan et al. 2011], Crampin [2012] claims that observable changes in shear-wave splitting can predict large earthquakes on short time scales with high reliability

Shear wave splitting as a proxy for stress forecast of the case of the 2006 Manyas-Kus Golu (M_b = 5.3) earthquake [PDF]

Natural Hazards and Earth System Sciences, 2012
The 2006 Mb = 5.3 Manyas-Kus Golu (Manyas) earthquake has been retrospectively "stress-forecasted" using variations in time-delays of seismic shear wave splitting to evaluate the time and magnitude at which stress-modified microcracking reaches fracture ...

Discovery of the Acoustic Faraday Effect in Superfluid 3He-B

, 1999
We report the discovery of the acoustic Faraday effect in superfluid 3He-B. The observation of this effect provides the first direct evidence for propagating transverse acoustic waves in liquid 3He, a mode first predicted by Landau in 1957.

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

Interlayer electronic hybridization leads to exceptional thickness-dependent vibrational properties in few-layer black phosphorus

, 2015
Stacking two-dimensional (2D) materials into multi-layers or heterostructures, known as van der Waals (vdW) epitaxy, is an essential degree of freedom for tuning their properties on demand.

Anisotropy and mantle flow of the Indo-Burma subduction zone from shear wave splitting and shear wave splitting tomography

, 2023
The Indo-Burma subduction zone lies on the eastern boundary of the 1500 km long Alpine-Himalayan orogenic belt. Despite highly oblique plate motion with limited arc development, convergence is still ongoing with the potential to generate megathrust earthquakes that could affect more than 140 million people. This sub-aerial subduction system provides an

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.
