Risk‐Targeted Seismic Design Maps for Mexico

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Risk‐targeted seismic design maps for Mexico are presented. Risk‐targeted approach establishes an acceptable risk level, measured with the annual collapse probability, to determine seismic design coefficients. Seismic design maps are calculated for an annual probability of collapse of 1 × 10−4 and 2 × 10−4.

Analysis of Stress Variation Characteristics of Jiangling Depression, Hubei, China, Based on Jingzhou Well Water Level and GNSS Data

Geofluids
There have been many M≥3.0 earthquakes in and around the Jiangling Depression in history, and the stress variation can directly affect the preparation of surrounding earthquakes. This paper innovatively uses the variation characteristics of Jingzhou well

Satellite Remote Sensing in Seismology. A Review

Remote Sensing, 2009
A wide range of satellite methods is applied now in seismology. The first applications of satellite data for earthquake exploration were initiated in the ‘70s, when active faults were mapped on satellite images.

Comparative Insights Into the Structural, Electronic, Elastic, Vibrational, and Optical Properties of Rare‐Earth Palladium Borides RBPd3 (R = Lu, Yb)

Nano Select, EarlyView.
This study focuses on the ground‐state properties of two rare earth palladium borides, LuBPd3 and YbBPd3. The WIEN2k package is used to investigate the properties. The compounds’ exceptional thermal and optoelectronic properties make them suitable for high‐temperature applications, UV absorbers, and infrared (IR) shielding materials.

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

physica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

New Advances in the Deep Structure of the Pamir Plateau: A Review

Acta Geologica Sinica - English Edition, EarlyView.
Abstract The Pamir Plateau is situated at the northwestern edge of the India–Eurasia Plate collision zone, making it a key region for studying continental collision and plateau uplift. The deep structure and dynamic processes of this region have long been of great scientific interest.
