Spatiotemporal Analysis of Climate Variability and Natural Disaster Patterns in Brazil Using Self-Organizing Maps

This study demonstrates that Self-Organizing Maps (SOM) with optimized parameters effectively identify distinct spatiotemporal patterns in Brazil's natural disaster data, revealing that precipitation variability and administrative indicators are key drivers for regional clustering and offering valuable insights for climate risk management and adaptive policy planning.

Modified Normalized Fried Mann Fractal Dimension For Characterizing Pore Structure in Khuff Carbonate Reservoirs, Central Saudi Arabia

This study demonstrates that the Modified Normalized Friedmann Method is a highly reliable alternative to the conventional normalized pore-radius approach for characterizing pore-structure fractal behavior in Khuff carbonate reservoirs, as evidenced by an almost perfect linear correlation between the two methods.

Determinants of climate information use among wheat farmers in Golestan Province, Iran: roles of perception, communication channels, and socioeconomic factors

This study of 383 wheat farmers in Golestan Province, Iran, reveals that belief in climate change, perception of local warming, and access to national advisory hotlines are the primary drivers of climate information use, outweighing socioeconomic factors and highlighting the need for enhanced extension communication and risk awareness strategies.

Three-dimensional deep electrical resistivity structure beneath the Kii Peninsula, southwestern Japan: fluids and their contribution to seismic activities

By mapping the 3-D electrical resistivity structure beneath the Kii Peninsula, this study reveals that impermeable acidic plutons act as barriers to fluid migration from the subducting Philippine Sea slab, thereby controlling the accumulation of slab-derived fluids that trigger deep low-frequency earthquakes and guiding fluid flow that influences microseismicity.

MAOM stoichiometry and Fe-P coupling reveal soil-mediated pathways linking climate to grassland vegetation on the Mongolian Plateau

This study demonstrates that soil-mediated pathways, specifically the coupling of reactive iron and phosphorus within mineral-associated organic matter, act as a critical filter transmitting climate signals to shape grassland vegetation structure and diversity across the Mongolian Plateau.

Prediction of soil selenium content and model optimization for a watershed in the Taihang Mountains based on machine learning models

This study demonstrates that Support Vector Machine (SVM) is the optimal model for predicting soil selenium content in the rugged Taihang Mountains, revealing that soil organic matter, cadmium, and lead are the dominant geochemical drivers of its spatial distribution.
