Multi‐Method Geophysical Surveys Between and Around the Kerlescan and the Manio Megalithic Alignments in Carnac (Morbihan, France)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The Carnac alignments in Morbihan (France) are among the most famous Neolithic sites of the world. Paradoxically, they have benefited little from a thorough renewal of archaeological data over the past century. There are many reasons for this, but it is mainly because the site has been regarded more as a monument to visit and protect than as ...

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.

Robinow syndrome DVL1 variants disrupt morphogenesis and appendage formation in a Drosophila disease model

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Robinow syndrome is a rare developmental syndrome caused by variants in genes in Wnt signaling pathways. We previously showed that expression of patient variants in Dishevelled 1 (DVL1) in Drosophila and chicken models disrupts the balance of canonical and non‐canonical Wnt signaling.

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Internal framework and geochemistry of the Carboniferous Huaco granite pluton, Sierra de Velasco, NW Argentina [PDF]

open access: yes, 2018
The A-type Huaco granite pluton of the Velasco range (Sierras Pampeanas of northwest Argentina) is formed by three coeval granitic facies and contains subordinate coeval-to-late facies, as well as enclaves, dikes and stocks that show different temporal ...

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

open access: yesEnergy Science &Engineering, EarlyView.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...
