Enhancing volcanic eruption simulations with the WRF-Chem v4.8 [PDF]

Geoscientific Model Development
Volcanic eruptions are one of the major natural hazards, exerting profound effects on the environment and climate. The emissions associated with such eruptions pose substantial risks to terrestrial systems and public health, particularly through the ...

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Seismic Data, Photographic Images and Physical Modeling of Volcanic Plumes as a Tool for Monitoring the Activity of Nevado del Ruiz Volcano, Colombia

Frontiers in Earth Science, 2018
Quantification of volcanic plume parameters is a fundamental task to characterize the behavior of an active volcano. The volcanic plume mass, flow rate and ash injection were determined from seismic data, in addition to photographic images and ...

Dendritic Cell α‐Ketoglutarate Regulates Tfh Polarization in Allergy

Allergy, EarlyView.
Allergen induces a dendritic cell metabolism shift toward glutaminolysis with α‐ketoglutarate as a regulator of Tfh subset polarization. Glutaminolysis is required for DC allergen uptake, co‐stimulatory molecule expression, and CLR expression. Modulation of glutaminolysis, JmjD3 histone demethylation, or HIF‐1α degradation alters Tfh polarization and ...

Improving volcanic ash fragility functions through laboratory studies: example of surface transportation networks

Journal of Applied Volcanology, 2017
Surface transportation networks are critical infrastructure that are frequently affected by volcanic ash fall. Disruption to surface transportation from volcanic ash is often complex with the severity of impacts influenced by a vast array of parameters ...

Maternal Perinatal Gut Microbiome Is Shaped by Traditional Farming Lifestyle and Associated With Early Childhood Atopic Disease

Allergy, EarlyView.
We assessed whether the maternal perinatal gut microbiome and serum SCFA and cord blood SCFA differ between traditional farming and urban dyads. Women following a farming lifestyle had increased microbial diversity, several differentially abundant bacterial species and functional pathways, and increased circulating SCFA. Overall maternal gut microbiome

Bilateral Supracondylar Process in a Subadult in the Late Antique Age: A Case Report

Archaeometry, EarlyView.
ABSTRACT During the excavation procedures for the railway trait Napoli‐Cancello, in the city of Afragola (Naples), several burials dating back to the Late Antique Age were found. One of them was an amphora burial (enchytrismòs) and contained the skeletal remains of a subadult individual affected by bilateral supracondylar process. Supracondylar process

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

Boreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.
