The Changing Face of the Lithosphere‐Asthenosphere Boundary: Imaging Continental Scale Patterns in Upper Mantle Structure Across the Contiguous U.S. With Sp Converted Waves

Geochemistry, Geophysics, Geosystems, 2018
Juxtaposed terranes of highly varied tectonic history make up the contiguous U.S.: the tectonically active western U.S., the largely quiescent Archean and Proterozoic cratons of the central U.S., and the Phanerozoic orogen and rifted margin of the ...

High-quality control of receiver functions using a capsule neural networkKey points

Earthquake Science
The Red Sea-Gulf of Suez-Cairo-Alexandria Clysmic-Trend in northern Egypt is the main earthquake zone in the country, with a moderate-to-high seismic hazard and a history of significant earthquakes caused by rifting and active faulting.

Crustal structure of the central Cathaysia block in South China derived from receiver functionsKey points

Earthquake Science
The Cathaysia block in Southeast China has undergone complex compression, collision and tectonic evolution processes, which have led to the formation of rich granites and polymetallic ores.

Imaging the Low Dip Onset of the Gibraltar Arc Subduction in the Gulf of Cádiz Using OBS Receiver Functions

Geophysical Research Letters
Using P and S‐wave receiver function analysis we investigate the lithospheric structure in the Gulf of Cádiz through a combination of ocean‐bottom seismometers and onshore seismic stations located in southwest Iberia and northwest Africa.

Hand function assessment in patients receiving haemodialysis

Swiss Medical Weekly, 2003
To assess the usefulness of Duruöz's Hand Index (DHI) in patients undergoing haemodialysis.Patients receiving haemodialysis for more than 2 months were recruited randomly. Demographic, clinical and functional characteristics of patients were evaluated.

Evidence of a Low‐Velocity Zone in the Upper Mantle Beneath Cumbre Vieja Volcano (Canary Islands) Through Receiver Functions Analysis

Geophysical Research Letters
Oceanic volcanic islands have a complex internal structure due to their geological evolution. La Palma is the second youngest in the Canary Islands. Historical eruptions occurred in the Cumbre Vieja (CV) volcanic system, including the last 2021 Tajogaite

Slab pileup in the mantle transition zone and the 30 May 2015 Chichi‐jima earthquake

Geophysical Research Letters, 2016
The 30 May 2015 Chichi‐jima M8 earthquake is one of the largest deep focus earthquakes ever recorded and its depth of 682 km puts it near the base of the mantle transition zone.

Lithospheric Foundering in Progress Imaged Under an Extinct Continental Arc

Geophysical Research Letters
A long‐standing question is how felsic continental crust is differentiated from its mafic parent mantle magmas. One currently proposed fundamental mechanism is lithospheric foundering and loss of dense material into the mantle.

On receiver functions with sediment reverberations

Geophysical Journal International
SUMMARY Teleseismic P-wave receiver function (RF) analysis is a powerful tool for probing deep structures; however, its application to regions with sedimentary cover remains challenging. The interference by converted and reflected waves related to the sediments can form strong reverberations and render individual phases unidentifiable,
