Shear-wave attenuation anisotropy: a new constraint on mantle melt near the Main Ethiopian Rift

Seismica
The behaviour of fluids in preferentially aligned fractures plays an important role in a range of dynamic processes within the Earth. In the near-surface, understanding systems of fluid-filled fractures is crucial for applications such as geothermal ...

Anisotropy and Energy Evolution Characteristics of Shales: A Case Study of the Longmaxi Formation in Southern Sichuan Basin, China

Geofluids
To obtain the influence of anisotropy and energy evolution characteristics on wellbore stability, the acoustic and mechanical anisotropy characteristics of shales are studied through various experiments, including scanning electron microscopy, ultrasonic

Seismic anisotropy and mantle dynamics beneath Maitri Station in central Dronning Maud Land, East Antarctica: new insights from shear wave splitting analysis of core-refracted and direct S-phases

Polar Research
To elucidate the Gondwana supercontinent, we investigate mantle dynamics in Dronning Maud Land, Antarctica, using shear wave splitting analysis. This involves 12 S-phase teleseismic events and 38 core refracted phase (SKS, SKKS, PKKS and PKS) events ...

Coherent Seismic Anisotropy Pattern Across Southern Africa Revealed by Shear Wave Splitting Measurements

Earth and Space Science
We report new PKS, SKS, and SKKS splitting measurements for 88 seismic stations in Namibia, Botswana, South Africa, and Mozambique. When combined with measurements from previous studies, the ensemble of measurements shows a fairly uniform NNE to NE (∼41°

Conservation of Angular Momentum in a Flux Qubit

, 2011
Oscillations of superconducting current between clockwise and counterclockwise directions in a flux qubit do not conserve the angular momentum of the qubit.
