Forecasting Analysis of Heavy Metal Concentrations in the Ciliwung River Using Random Forest and Xgboost Methods

This study utilizes Random Forest and XGBoost algorithms to forecast heavy metal (Pb, Cd, Hg) concentrations in the Ciliwung River for 2024–2030, finding that XGBoost offers superior predictive accuracy and projecting that while levels will remain within Indonesia's Government Regulation No. 22 of 2021 Class II standards, continued monitoring is essential as Cd and Pb approach threshold limits.

Anticyclonic Eddies in the northeastern Japan/East Sea: simulation, observation and formation mechanisms

This paper investigates the formation, evolution, and dynamics of mesoscale anticyclonic eddies in the understudied northeastern Japan/East Sea using a high-resolution ROMS simulation validated by satellite altimetry, CTD measurements, and drifter data, identifying inertial instability as the primary mechanism driving their growth.

Compound climate hazards erode energy-system resilience through transmission infrastructure

This study reveals that compound climate hazards increasingly converge on global transmission infrastructure, where concurrent multi-line failures—rather than isolated disruptions—severely undermine grid redundancy and customer reliability, thereby making transmission resilience a critical prerequisite for a successful clean-energy transition.

Beyond Daytime Thresholds: Downscaled Population Exposure and Compound Heat Hazard Projections in Andhra Pradesh, India

This study introduces a novel Compound Heat Hazard Index and a high-resolution population downscaling method to reveal that nighttime heat exposure in Andhra Pradesh is intensifying faster than daytime heat, highlighting a critical gap in current heat action plans and offering a low-cost, transferable framework for improving urban resilience in the Global South.

Asymmetric day–night warming across Pakistan, 1980–2025: diurnal temperature range compression in the irrigated Indus plains and expansion in the Karakoram

This study reveals that Pakistan's warming from 1980 to 2025 is highly asymmetric, characterized by a compression of the diurnal temperature range in the irrigated Indus plains due to rapidly rising minimum temperatures, while the Karakoram region experiences an expansion of the range as maximum temperatures increase faster than minimums.

Geochemistry of Alluvial Deposits from the Mouanko Region (Littoral Basin, Cameroon): Implications for Provenance, Depositional Environment, and Associated Mineralizations

This study utilizes lithogeochemical analysis of Mouanko region alluvial deposits to identify three distinct sedimentary poles reflecting varying paleoclimatic and tectonic histories, ultimately concluding that while precious metal potential is negligible, the aluminous clays offer significant economic value for ceramic and eco-construction materials.

Lithostratigraphic Control of Vertical Water Fluxes in Chalk Aquifer Systems: An Integrated Geophysical and Sedimentological Approach

This study demonstrates that specific lithostratigraphic successions and weathered interface facies at the loess–chalk boundary in northern France critically control vertical water fluxes and groundwater recharge by regulating perched water formation and hydraulic conductivity within the Senonian-Turonian chalk aquifer system.

Multivariate Pollution Risk Assessment of Natural Radionuclides and Heavy Metals in Topsoils of Nonwa, Rivers State, Nigeria

This study assesses the multivariate pollution risks of natural radionuclides and heavy metals in Nonwa, Rivers State, finding that while most radiological levels are within safety limits, specific communities face elevated indoor cancer risks and heavy metal contamination from petrogenic and agrochemical sources, prompting recommendations for lime application to mitigate toxicity and groundwater pollution.

Analysis of Near-Surface Atmospheric Turbulence and Its Intermittency in the Hinterland of the Gurbantunggut Desert in Winter

This study analyzes winter turbulence in the Gurbantunggut Desert, revealing that while strongly stable stratification dominates the environment and suppresses overall turbulence, intermittent burst events remain a critical mechanism that significantly enhances kinematic heat exchange despite their short duration.
