Building blocks for 3D fuelbeds: object-centered scanning and meshing protocol

This paper introduces an object-centered scanning and meshing protocol using industrial-grade laser scanners to generate high-precision 3D digital twins of individual wildland fuel particles, establishing a foundational framework for improving fire behavior, emissions, and ecological modeling through detailed structural characterization.

Analysis of Microscopic Flow Behavior and Main Controlling Factors of Water Huff-n-Puff in Tight Reservoirs under the Influence of Salinity

This study elucidates the microscopic mechanisms and main controlling factors of water huff-n-puff in tight reservoirs under salinity influence, revealing that low-salinity injection enhances oil recovery by synergistically leveraging pressure differential, capillary imbibition, and ion osmosis to mobilize residual oil from low-permeability zones.

Persistence Without Resilience: Long-Term Degradation of Coral Populations in an Extreme Reef System

A 15-year study of the Ras Ghanada reef in the Persian/Arabian Gulf reveals that chronic thermal stress has driven a catastrophic functional decline, characterized by a 68% to <10% drop in coral cover, the loss of large colonies and dominant species, and a shift toward a degraded assemblage dominated by small, partially mortally affected colonies.

Spatial Distribution of Size-Resolved Particulate Matter and Associated Heavy Metal Health Risks in a Tier-2 Indian City During Winter

This study reveals that in Coimbatore, a Tier-2 Indian city, winter particulate matter and associated heavy metals exhibit a distinct urban-to-rural gradient with severe non-carcinogenic health risks and significant life expectancy reductions, particularly in landfill and urban zones where fine particles act as toxic metal carriers.

Optimization of the sequential elution technique for geochemical background monitoring: the influence of bioindicator sample mass on the reproducibility of analysis

This study demonstrates that increasing the bioindicator sample mass to 50 g in the sequential elution technique significantly improves analytical reproducibility and accuracy for geochemical background monitoring by mitigating the effects of uneven element distribution in mosses and lichens.

Sediment organic carbon sources, accumulation and stock estimates in a temperate lake over the past 10,000 years in Ireland

This study reconstructs the past 10,000 years of organic carbon accumulation in Ireland's Lough Feeagh using sediment cores and hydroacoustic data, revealing that terrestrial sources primarily drive sediment carbon stocks, which are estimated at a median of 205 kT OC, thereby highlighting the significant role of temperate lakes in global carbon storage.

Hydrologic pathway controls on surface and groundwater nutrient delivery under agricultural fallow and crop rotation in the Fuxian Lake watershed

This study demonstrates that implementing agricultural fallow in the Fuxian Lake watershed significantly reduces nutrient inflows to the lake, with the effectiveness of these reductions depending on the timing and spatial extent of the fallow, while shifting the dominant nutrient transport pathway from groundwater leaching to surface runoff.

Climate Change, Urbanisation, and Sustainability Outcomes in Sub-Saharan Africa

Using panel data from 32 Sub-Saharan African countries (1996–2023), this study reveals that rising temperatures and persistent droughts generally undermine economic, environmental, and social sustainability, while precipitation offers some benefits, with these negative impacts intensifying beyond critical thresholds and varying significantly across subregions and sectors.
