Seed layer formation by deposition of micro‐crystallites on a revolving substrate. Part II: application to some nonlinear effects

Acta Crystallographica Section B, EarlyView.
A method of averaging the material coefficients of crystallites deposited at an angle onto a revolving substrate isapplied to effective nonlinear dielectric, piezoelectric and elastic constants, as well as linear pyroelectric coefficients, for triclinic crystals.The matrix method of averaging material coefficients of crystallites deposited at an angle ...

Efficient least-squares imaging of a complex mountainous area in China using LsmGANs

Frontiers in Earth Science
Least-squares migration (LSM) compensates for illumination heterogeneity and resolution loss caused by finite acquisition apertures, complex overburden structures, and band-limited recordings, thereby producing images of substantially higher fidelity ...

Seismic detection of post-perovskite inside the Earth [PDF]

, 2015
Since 2004, we have known that perovskite, the most abundant mineral in the lower mantle, has the capacity to transform to a denser structure, postperovskite, if subjected to sufficiently high temperature and pressure.

An Examination of the Reasons for, and Variability of, the Differences Between Response Spectra and Pseudo Response Spectra

Earthquake Spectra, Volume 42, Issue 4, November 2026.
For many decades, it has been common practice to overlook the differences between response spectra and pseudo response spectra. This practice stems from analyses indicating that the average difference between response spectra and pseudo response spectra is negligible for a viscous damping ratio of 5%, which is near‐universally adopted.

Seismic signature of a hydrous mantle transition zone [PDF]

, 2016
Although water has a major influence on tectonic and other geodynamic processes, little is known about its quantity and distribution within the deep Earth.

Editorial: Women in science: seismology 2022 [PDF]

, 2023
Seismology is the study of earthquakes and of the propagation of seismic waves within the Earth. Seismologists study the Earth’s—and other planets’ interiors; provide detailed information on the shallow subsurface composition, where they help find ...

Application of artificial intelligence techniques in seismology and engineering seismology

, 1992
In the field of risk evaluation and seismic hazard assessment, it is necessary to codify a great quantity of aspects of the so called knowledge and to supply an intelligent support for the not-well-defined problems (data uncertainty, lack of rigorous ...

Large‐scale mantle discontinuity topography beneath Europe: Signature of akimotoite in subducting slabs [PDF]

, 2016
The mantle transition zone is delineated by seismic discontinuities around 410 and 660 km, which are generally related to mineral phase transitions. Study of the topography of the discontinuities further constrains which phase transitions play a role and,

Simulator‐Based Bayesian Inference of Enhanced Geothermal Reservoir Properties

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Inversions of dynamic multi‐scale multi‐physics subsurface system properties rely on the effective sampling of high‐dimensional parameter spaces and are thus notoriously difficult to perform. The associated models are defined by complex nonlinear relationships with potentially stochastic components, which lead to analytically intractable ...

Devito (v3.1.0): an embedded domain-specific language for finite differences and geophysical exploration [PDF]

Geoscientific Model Development, 2019
We introduce Devito, a new domain-specific language for implementing high-performance finite-difference partial differential equation solvers. The motivating application is exploration seismology for which methods such as full-waveform inversion and ...
