7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Geodynamics of the Yellowstone hotspot and mantle plume: Seismic and GPS imaging, kinematics, and mantle flow [PDF]

Journal of Volcanology and Geothermal Research, 2009
Abstract Integration of geophysical and geological data show that the Yellowstone hotspot resulted from a mantle plume interacting with the overriding North America plate, a process that has highly modified continental lithosphere by magmatic and tectonic processes and produced the 16-17 Ma, 700-km-long Yellowstone-Snake River Plain (YSRP) silicic ...

Integrated Clinical and Proteomic Profiling of CD19 Chimeric Antigen Receptor T Cell Therapy in Progressive Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Objective To characterize the clinical, immunologic, and proteomic changes associated with CD19 chimeric antigen receptor T cell therapy in patients with progressive systemic sclerosis (SSc). Methods Patients with progressive SSc received CD19 chimeric antigen receptor (CAR)‐T cell therapy and were observed longitudinally for safety, clinical efficacy,

Ruthenium‐Titania Interface‐Mediated Water Activation for High Turnover Frequency in Alkaline Hydrogen Evolution

Carbon Energy, EarlyView.
Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

Generation of Channelized Mantle Flow Beyond the Rift Zone Accelerated by Thermal Heterogeneity and Rift Propagation

Geochemistry, Geophysics, Geosystems
Rifting is a tectonic process that leads to extensive magmatic activity, continental breakup, and the formation of new oceanic crust. The interplay between rifting and dynamic mantle flow driven by thermal heterogeneity in the mantle along the rift‐axis ...

The Influence of Lithospheric Thickness Variations Beneath Australia on Seismic Anisotropy and Mantle Flow

Geochemistry, Geophysics, Geosystems, 2023
Rapid plate motion, alongside pronounced variations in age and thickness of the Australian continental lithosphere, makes it an excellent location to assess the relationship between seismic anisotropy and lithosphere‐asthenosphere dynamics. In this study,

Geomagnetic Impulses and the Electrical Conductivity of the Lower Mantle [PDF]

, 1991
This thesis is an investigation of the changes in the magnetic field as measured at the surface of the Earth on the time-scale of months to decades. In particular the phenomena of geomagnetic "impulses" or "jerks" are investigated.

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Lowermost Mantle Flow at Thermochemical Piles Constrained by Shear Wave Anisotropy: Insights From Combined Geodynamic and Mantle Fabric Simulations at Global Scale

Geochemistry, Geophysics, Geosystems
Seismic anisotropy is observed in the lowermost few hundred kilometers of the mantle. This anisotropy likely signifies strong deformation, possibly caused by mantle flow interacting with the edges of Large Low‐Shear‐Velocity Provinces (LLSVPs) or by the ...

Transient Injection of Flow: How Torn and Bent Slabs Induce Unusual Mantle Circulation Patterns Near a Flat Slab

Geochemistry, Geophysics, Geosystems, 2023
Torn and bent slabs are usually associated with flat‐slab subduction where the descending plate develops a horizontal geometry beneath the overlying continent.
