Moment tensor solutions and stress regime along the Northern Caribbean plate boundary off southeastern Cuba

Seismica
For a better understanding of the kinematics and mechanics of the Oriente transform fault, a left‑lateral boundary along Cuba's southern margin in the Caribbean, we use the seismic records to determine new deviatoric moment tensor solutions by full ...

A novel magnetic dipole inversion method based on tensor geometric invariants

AIP Advances, 2020
Currently, when the existing magnetic dipole inversion methods are used, the classification process heavily relies on the localization results, and the localization error can significantly deteriorate the classification results.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Network Sensitivity Solutions for Regional Moment-Tensor Inversions [PDF]

Bulletin of the Seismological Society of America, 2010
Well-resolved moment-tensor solutions reveal information about the sources of seismic waves. In this paper, we introduce a new way of assessing confidence in the regional full moment-tensor inversion via the introduction of the network sensitivity solution (NSS).

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

Advanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

A moment tensor inversion approach based on the correlation between defined functions and waveforms

, 2021
The moment tensor inversion is a commonly-used method to interpret source mechanisms of microseismicity. In the inversion for real data (e.g. microseismicity recorded during hydraulic fracturing), the waveforms recorded by sensors can be the mixtures of ...

Apparent Non-Double-Couple Components as Artifacts of Moment Tensor Inversion

Seismica
Compilations of earthquake moment tensors from global and regional catalogs find pervasive non-double-couple (NDC) components with a mean deviation from a double-couple (DC) source of around 20%.
