Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

Evaluation of different geostatistical methods based on GIS for predicting and zoning salinity invasion of aquifers of West Azarbaijan [PDF]

محیط زیست و مهندسی آب, 2016
In coastal aquifers, infiltration and internal extending seawater is the most common reason for the increased salinity. Locating adjacent to the hypersaline lake and a sharp drop in groundwater in the region has exposed West Azerbaijan Province to ...

Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

Early‐Life Nutritional Supplements, Household Environments, and Air Pollution Associated With Children's Helicobacter pylori Infection: A Chinese Multicenter Mother‐Child Study

Safety Science and Technology, EarlyView.
Early‐life intake of nutritional additives, particularly during pregnancy and the early postnatal period, reduces the risk of Helicobacter pylori infection (HPI) in children by enhancing immune function and preventing gastrointestinal infections through proper nutrition, supporting the “(Pre‐)Fetal origins of HPI” hypothesis through the “gut–uterine ...

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

Meteoritics &Planetary Science, EarlyView.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Analysis of Models to Estimate Morbidity Rates of Respiratory Diseases Through Deep Learning

Tropical Medicine &International Health, EarlyView.
ABSTRACT Respiratory diseases remain a challenge in Brazil due to socioeconomic inequalities and environmental risks that intensify population vulnerability. This study compared XGBoost with a deep learning model using stacked Gated Recurrent Units (GRU), trained with morbidity data from respiratory diseases and exogenous variables such as per capita ...
