A Socio-Seismology Experiment in Haiti

open access: yesFrontiers in Earth Science, 2020
Earthquake risk reduction approaches classically apply a top-down model where scientific information is processed to deliver risk mitigation measures and policies understandable by all, while shielding end-users from the initial, possibly complex ...

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

open access: yesNano 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.

A high-precision borehole gravimeter

open access: yesGeodesy and Geodynamics, 2011
The paper describes the working principle and structure of a newly designed high-precision (micro-gal) gravimeter, which is basically a vertically suspending spring-weight system, using a highly sensitive capacitance sensor of movement in a controlled ...

Using Vp$V_p$ and Vs$V_s$ to characterize the spatial extent of shear strengthening under a longleaf pine

open access: yesNear Surface Geophysics, EarlyView.
Abstract Tree roots modify the elastic and mechanical properties of soil. High‐resolution seismic refraction surveys offer a novel, noninvasive approach to characterize how roots impact the elastic properties of soil beneath trees. This study presents two perpendicular profiles of P‐wave (Vp$V_p$) and transversely polarized S‐wave (Vs$V_s$) velocities ...

Baseline correction for digital strong-motion records by using the pre-event portion

open access: yesGeodesy and Geodynamics, 2011
Baseline offset in digital strong-motion acceleration record and initial velocity can produce unrealistic results for ground velocity and displacement derived from the acceleration by integration.

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

open access: yesphysica 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 ...

A statistical investigation of pre-earthquake ionospheric TEC anomalies

open access: yesGeodesy and Geodynamics, 2011
Previous researches show that the total electron content (TEC) in the ionospheric exhibits anomalous disturbances a few days or hours prior to earthquakes.

On the realization of seismic microzonation of Almaty (Kazakhstan) in ground accelerations based on the “continual” approach

open access: yesGeodesy and Geodynamics, 2020
Seismic microzonation for Almaty city for the first time use probabilistic approach and hazard is expressed in terms of not only macroseismic intensity, but also Peak Ground Acceleration (PGA).

MHD Waves and Coronal Seismology: an overview of recent results

open access: yes, 2012
Recent observations have revealed that MHD waves and oscillations are ubiquitous in the solar atmosphere, with a wide range of periods. We give a brief review of some aspects of MHD waves and coronal seismology which have recently been the focus of ...
