A seismological study of the mantle beneath Iceland [PDF]

open access: yes, 2000
Iceland has long been thought to be underlain by a thermal upwelling, or plume, rising from deep within the mantle. This study tests this hypothesis, by a) seeking evidence for a plume in the lower mantle in azimuth anomalies at the NORSAR array and b ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Monogenetic Near‐Island Seamounts in the Galápagos Archipelago

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Rarely have small seamounts on the flanks of hotspot derived ocean‐island volcanoes been the targets of sampling, due to sparse high‐resolution mapping near ocean islands.

The Zagros Core: Deformation of the continental lithospheric mantle [PDF]

open access: yes
The Zagros of Iran form one of the youngest collisional orogenic belts on Earth. At shallow depths, shortening across the Zagros is accommodated by folding in the sediments, high-angle thrust faulting in the basement and thickening of the lower crust ...

Pathological hippocampal–cortical hypersynchronization disrupts memory in temporal lobe epilepsy: A multimodal intracranial electroencephalographic–functional magnetic resonance imaging study

open access: yesEpilepsia, EarlyView.
Abstract Objective Memory impairment is a common comorbidity in temporal lobe epilepsy (TLE) and is thought to arise from hippocampal dysfunction and disrupted interactions within a distributed memory network involving medial temporal, frontal, and parietal cortical regions.

Pulsated Global Hydrogen and Methane Flux at Mid‐Ocean Ridges Driven by Pangea Breakup

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Molecular hydrogen production occurs through the serpentinization of mantle peridotite exhumed at mid‐ocean ridges. Hydrogen is considered essential to sustain microbial life in the subsurface; however, estimates of hydrogen flux through geological time ...

Plant‐Derived Extracts Disrupt Biofilm Formation and Quorum Sensing in Yersinia enterocolitica: Insights From GC‐MS and Molecular Docking

open access: yesFood Chemistry International, EarlyView.
The graphical abstract represents how natural plant products that preferentially target the specific receptors of quorum sensing could be developed to combat biofilms linked to Yersinia enterocolitica using the potent abilities of protein–ligand complexes with high docking scores.

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

open access: yesGeological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Trace element mass balance in hydrous adiabatic mantle melting: The Hydrous Adiabatic Mantle Melting Simulator version 1 (HAMMS1)

open access: yesGeochemistry, Geophysics, Geosystems, 2014
A numerical mass balance calculation model for the adiabatic melting of a dry to hydrous peridotite has been programmed in order to simulate the trace element compositions of basalts from mid‐ocean ridges, back‐arc basins, ocean islands, and large ...

Evaluation of Small Molecular Polypeptides from the Mantle of Pinctada Martensii on Promoting Skin Wound Healing in Mice

open access: yesMolecules, 2019
Skin wound healing, especially chronic wound healing, is a common challenging clinical problem. It is urgent to broaden the sources of bioactive substances that can safely and efficiently promote skin wound healing.
