Physics-Regularized Neural Networks for Urban Air Quality Prediction Under Meteorological Variability: Emission Source Estimation from Sparse Observations in London

This paper proposes a physics-regularized neural network framework that integrates sparse urban monitoring data with meteorological reanalysis and atmospheric transport physics to reconstruct spatially continuous PM2.5 emission-related fields in London, effectively constraining ill-posed inverse solutions to provide physically plausible diagnostic insights under data-scarce conditions.

Radiological Risk Assessment of Radionuclide Contamination in Sediment and Water of the Halda River Estuary, Bangladesh

A radiological risk assessment of the Halda River Estuary in Bangladesh using HPGe gamma-ray spectrometry found that naturally occurring radionuclide levels in sediment and water are below global averages and pose no current threat to biodiversity or human health, though future monitoring is recommended to anticipate potential increases from natural or anthropogenic sources.

Climate change and changing levels of risk exposure for ships operating in the Global Arctic

This study systematically evaluates navigational risk exposure for ships in the Global Arctic from 2015 to 2021, revealing that while a doubling of maritime activity coincided with an overall decrease in risk due to changing sea ice conditions, specific vessel types and regions such as the Kara Sea and Baffin Bay remain significantly more vulnerable.

Dynamic–thermal coupling drives increasing oceanic eddy-to-ice heat fluxes in the Arctic

This study reveals that as Arctic sea ice retreats, dynamic–thermal coupling between friction-velocity fluctuations and upper-ocean temperature anomalies drives an increasing ocean-to-ice heat flux via mesoscale eddies, a state-dependent mechanism not captured by current climate models.

Anatomizing spatiotemporal LULC changes and anthropogenic drivers of forest loss in Eastern Assam of India

This study utilizes geospatial analysis and field data to demonstrate that between 2000 and 2023, Dibrugarh district in Eastern Assam experienced significant forest loss driven primarily by the expansion of tea plantations, urbanization, and agricultural activities, necessitating urgent policy interventions for sustainable land management.

Fracture development mechanism of borehole walls in deep drilling

This study integrates numerical simulations, theoretical analysis, and laboratory experiments to reveal that thermal damage, horizontal in-situ stress, and drilling fluid pressure collectively govern the evolution and morphology of borehole wall fractures in deep granite drilling, providing a theoretical basis for enhancing wellbore stability and optimizing drilling fluid technologies.

Human behavioral responses to climate change reshape climate projections

By integrating human behavioral responses into climate models, this study reveals that factors like action confidence and climate anxiety can dynamically reshape future warming trajectories by up to ±1°C, demonstrating that human behavior is an active component of the climate system capable of either amplifying or mitigating climate change depending on the specific emissions pathway.

Enhancing European soil monitoring with citizen science data

This study demonstrates that integrating citizen science data with existing European monitoring programs, particularly for soil pH, can effectively enhance large-scale soil monitoring by improving digital soil mapping accuracy and expanding coverage to underrepresented environments like urban soils.
