Development of a seismic site-response zonation map for the Netherlands [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2022
Earthquake site response is an essential part of seismic hazard assessment, especially in densely populated areas. The shallow geology of the Netherlands consists of a very heterogeneous soft sediment cover, which has a strong effect on the amplitude of ...

Strong-Motions From Damaging Moderate Magnitude (5.9 ≥ Mw) Earthquakes in Japan Recorded by K-NET and KiK-net

open access: yesFrontiers in Earth Science, 2021
Strong-motions from 79 moderate magnitude (5.9 ≥ Mw) earthquakes that caused various degrees of impact on humans and built-environment in Japan between 1996 and 2019, after the start of K-NET and KiK-net, are presented.

An efficient one-step site-directed deletion, insertion, single and multiple-site plasmid mutagenesis protocol [PDF]

open access: yes, 2012
Background: Mutagenesis plays an essential role in molecular biology and biochemistry. It has also been used in enzymology and protein science to generate proteins which are more tractable for biophysical techniques.

Observations and analyses of site amplification effects of deep liquefiable soil deposits by geotechnical downhole array

open access: yesYantu gongcheng xuebao, 2017
Based on the accelerations recorded from two downhole arrays instrumented by the Caltrans/CDMG project, the site amplification effects of deep liquefiable soil deposits are analyzed in both time and frequency domains, and several important features of ...

Azimuth-Dependent Site Amplification

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 1992
The strong motion accelerograms recorded at two stations of SMART-1 array have been analyzed to investigate azimuth-dependent site amplification. Fifteen earthquakes which triggered both accelerographs at rock site E02 and soil site E01 were selected for this study.

Exploring inferred geomorphological sediment thickness as a new site proxy to predict ground-shaking amplification at regional scale: application to Europe and eastern Türkiye [PDF]

open access: yesNatural Hazards and Earth System Sciences
To test whether a globally inferred sediment thickness value from geomorphological studies can be used as a proxy to predict earthquake site amplification, we derive site-amplification models from the relation between empirical amplification for sites ...

Gene amplification and insecticide resistance [PDF]

open access: yes, 2011
Pesticide resistance in arthropods has been shown to evolve by two main mechanisms, the enhanced production of metabolic enzymes, which bind to and/or detoxify the pesticide, and mutation of the target protein, which makes it less sensitive to the ...

Analysis of strong-motion data of the 1990 Eastern Sicily earthquake

open access: yesAnnals of Geophysics, 1995
The strong motion accelerograms recorded during the 1990 Eastern Sicily earthquake have been analyzed to investigate source and attenuation parameters. Peak ground motions (peak acceleration, velocity and displacement) overestimate the values predicted ...

Machine learning based ground motion site amplification prediction

open access: yesFrontiers in Earth Science, 2023
Site condition impact on seismic ground motion has been a complex but important subject in earthquake hazard analysis. Traditional studies on site amplification effect are either based on site response via wave propagation simulation or regression ...
