Micro/Nanoscale Acoustic Manipulation: From Particle Control to Autonomous Microswimmers. [PDF]
Adv Sci (Weinh)This conceptual framework illustrates acoustic technology as a multifunctional platform enabling passive particle manipulation across scales and autonomous propulsion of microswimmers. ABSTRACT Acoustic manipulation and propulsion technologies have emerged as powerful platforms for micro/nanoscale control, enabled by their non‐contact operation, label ...

Automated shear-wave splitting analysis for single- and multi- layer anisotropic media
Seismica, 2023 Shear-wave velocity anisotropy is present throughout the earth. The strength and orientation of anisotropy can be observed by shear-wave splitting (birefringence) accumulated between earthquake sources and receivers. Seismic deployments are getting ever

Symmetry-Driven Unconventional Magnetoelectric Coupling in Perovskite Altermagnets: From Bulk to the Two-Dimensional Limit. [PDF]
Adv Sci (Weinh)The symmetry‐driven coexistence of altermagnetism and (anti)ferroelectricity in perovskites shows a strong dimensional dependence. Upon reducing the system from bulk to the two‐dimensional limit, only C‐type antiferromagnetic order retains ferroelectrically switchable altermagnetism, whereas A‐ and G‐type orders become conventional antiferromagnets ...

The scatter of time-delays in shear-wave splitting above small earthquakes [PDF]
, 2004 Measurements of time-delays in seismic shear-wave splitting above small earthquakes typically display a scatter of often as much as ±80 per cent about the mean. Changes in the average time-delay appear to be related to changes of stress, but applications

Stress-dependent shear wave splitting and permeability in fractured porous rock
Journal of Rock Mechanics and Geotechnical Engineering, 2019 It is well known that shear wave propagates slower across than parallel to a fracture, and as a result, a travelling shear wave splits into two directions when it encounters a fracture.

Complex anisotropy beneath the Peruvian flat slab from frequency-dependent, multiple-phase shear wave splitting analysis [PDF]
, 2013 Flat or shallow subduction is a relatively widespread global occurrence, but the dynamics remain poorly understood. In particular, the interaction between flat slabs and the surrounding mantle flow has yet to be studied in detail.

Experimental observation of water saturation effects on shear wave splitting in synthetic rock with fractures aligned at oblique angles [PDF]
, 2015 Fractured rocks are known to exhibit seismic anisotropy and shear wave splitting (SWS). SWS is commonly used for fractured rock characterization and has been shown to be sensitive to fluid type. The presence of partial liquid/gas saturation is also known

Shear-wave splitting in the mantle of the pacific [PDF]
Geophysical Journal International, 1994 SUMMARY The bulk of previously known data on seismic anisotropy in the suboceanic mantle was obtained from observations of azimuthal variations of the surface-wave and P, velocities. Our study of azimuthal anisotropy in the mantle of the Pacific is based on observations of shear-wave splitting. The idea of our method of measurement (Vinnik & Farra 1992)
