Mid‐Cretaceous calcarenite in stone products from the Roman colony of Emona, Regio X (modern Ljubljana, Slovenia)

open access: yesArchaeometry, Volume 65, Issue 1, Page 17-35, February 2023., 2023
Abstract Over the course of studying stone products from the Roman colony of Emona (Regio X), stratigraphically undefined calcarenite that was used to make simple sepulchral and architectural stone products was detected. The calcarenite used is late Aptian to early Cenomanian in age.

CONSS: Contrastive Learning Approach for Semi-Supervised Seismic Facies Classification [PDF]

open access: yesarXiv, 2022
Recently, seismic facies classification based on convolutional neural networks (CNN) has garnered significant research interest. However, existing CNN-based supervised learning approaches necessitate massive labeled data. Labeling is laborious and time-consuming, particularly for 3D seismic data volumes.

Sedimentology and geochemistry of tufa and their relation to hydrochemistry of springs: An example of Abgarm Tufa of Kalat- east of Kopet- Dagh basin [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2017
Tufa is the non- marine carbonates that formed from cold to low temperature freshwater at low depth and low energy flow conditions. Abgarm’s tufa is a typical kind of these deposits.

The Upper Cretaceous (Santonian-Maastrichtian) phosphate deposits in the west of the Neiva subbasin, Upper Magdalena Valley, Colombia

open access: yesBoletín Geológico, 2022
De tiempo atrás se conoce que los fosfatos económicamente explotables en Colombia se encuentran en sucesiones sedimentarias marinas del Cretácico Superior (Cathcart y Zambrano, 1967; Mojica, 1987; Zambrano y Mojica, 1990).

Natural History of NAA15‐Related Neurodevelopmental Disorder Through Adolescence

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The NatA N‐terminal acetyltransferase complex is composed of the NAA10 catalytic subunit and the auxiliary subunits NAA15 and HYPK. While those with variants in the enzymatic subunit develop Ogden Syndrome, individuals with variants in the NAA15 coding region develop NAA15‐related neurodevelopmental syndrome, which presents with a wide array ...

Stratigraphic and geotechnical characterization of regionally extensive and highly competent shallow sand units in the southern North Sea

open access: yesBoreas, Volume 52, Issue 1, Page 78-98, January 2023., 2023
A detailed stratigraphic and geotechnical investigation of the uppermost 50 m below the sea floor was carried out for parts of the German North Sea sector using combined information from shallow seismic reflection surveys, 50‐m‐long sediment cores and cone penetration tests covering an area of ~150 km2.

Binary Segmentation of Seismic Facies Using Encoder-Decoder Neural Networks [PDF]

open access: yesarXiv, 2020
The interpretation of seismic data is vital for characterizing sediments' shape in areas of geological study. In seismic interpretation, deep learning becomes useful for reducing the dependence on handcrafted facies segmentation geometry and the time required to study geological areas.

THE N.A. GOLOVKINSKY’S FUNDAMENTAL FACIAL LAW — PROBLEMATICS AND NEW HORIZONS

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2018
Famous Russian geologist N.A. Golovkinsky published 150 years ago an important scientific work, where the phenomenon of lateral  displacement (movement) of homogeneous lithological layers  («slide» over time) was asserted.

Nanopore Sequencing Solves an Elusive Case of Sotos Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Sotos syndrome is a rare genetic disorder characterized by distinctive facial features, including a broad and prominent forehead, dolichocephaly, and learning disabilities ranging from mild to severe intellectual impairment. Affected individuals often show overgrowth in height and head circumference over two standard deviations.
