Prediction of Ceiling Temperature in Tunnel Fires Under Canyon‐Wind Conditions Using Ensemble Learning

open access: yesSafety Science and Technology, EarlyView.
A LightGBM‐based ensemble learning framework with SHAP interpretability analysis was developed for predicting ceiling temperature in canyon‐wind tunnel fires. The model demonstrated robust generalization (R2 = 0.7476) under unseen extreme conditions, with fire‐source location identified as the primary factor driving temperature evolution.

Spatiotemporal Characteristics of Climate Variation in Different Kinds of Landforms of Haihe River Basin

open access: yesShuitu baochi yanjiu, 2014
Over the past century, global climate has become warming significantly, which changed the regional hydrologic cycle potentially. In recent 50 years, temperatures keep increasing; water deficit is serious in Haihe River Basin, which has affected the ...

Sargassum Lung Syndrome: Air Flow Obstruction and Bronchial Inflammation Are Observed After Prolonged Exposure to Sargassum Gas Emissions in the Eastern Caribbean

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Sargassum inundation of Caribbean and American shorelines is a growing environmental hazard. Hydrogen sulfide (H2S) and ammonia (NH3) produced by decomposing Sargassum could be involved in airway obstruction and bronchial inflammation. The study was undertaken to evaluate the effects of exposure to H2S and NH3 gases emitted during Sargassum ...

Cloud-Capped Towers: Capturing Terrain Characteristics Using Topographic Functionals

open access: yesQuaestiones Geographicae, 2015
We introduce three related mathematical measures of terrain based on a particularly elegant combination of relief and steepness, which we term omnidirectional relief and steepness (ORS). One measure, reduced ORS (RORS), is particularly suited to creating

Fine‐scale spatio‐temporal niche partitioning enables coexistence of wild ungulates and livestock in a resource‐limited Himalayan landscape, India

open access: yesWildlife Biology, EarlyView.
Understanding how wild ungulates share space with domestic livestock is central to conservation planning in Himalayan multi‐use landscapes. This study focuses on multi‐axis niche relationships among six wild ungulates: hangul Cervus hanglu hanglu, Kashmir musk deer Moschus cupreus, Himalayan goral Naemorhedus goral, kashmir markhor Capra falconeri ...

Apex predators exploit advantageous snow conditions across hunting modes

open access: yesJournal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

The Climate Niche Pressure on the Yunnan–Guizhou Plateau Predominates the Diversification of Advertisement Calls in Frogs (Leptobrachella)

open access: yesIntegrative Zoology, EarlyView.
The diversification of advertisement calls is largely driven by climatic niche differentiation. Our results provide acoustic evidence for studies on ecological speciation in anurans.
