Explainable hybrid stacking ensemble method for hard rock pillar stability prediction and engineering applications

Deep Underground Science and Engineering, EarlyView.
This research proposes an interpretable hybrid stacking ensemble framework, optimized by the Sparrow Search Algorithm, to enhance hard rock pillar stability prediction. By integrating six machine learning models—k‐nearest neighbors, support vector machines, random forests, Gradient Boosting Decision Tree, eXtreme Gradient Boosting, and Light Gradient ...

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Probabilistic characterization of seepage‐induced tunnel face failure via a two‐phase double‐point material point method

Deep Underground Science and Engineering, EarlyView.
To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Spatial variation and predictors of plant species' intrinsic climate sensitivity across the conterminous United States

Ecography, EarlyView.
Understanding how species' sensitivity to climate varies spatially across their ranges and elucidating the important causes is essential for identifying ecologically meaningful geographic units and conservation actions for biodiversity. In this study, we estimated climatic occurrence niches of vascular plants to explore the spatial variation in species'

Nested Carbon Governance in Southeast Asia: Towards Just Nature‐Based Solutions?

Environmental Policy and Governance, EarlyView.
ABSTRACT Nature‐based solutions (NbS) have gained prominence as an integrated approach to addressing climate change and biodiversity loss while supporting sustainable development. Yet, their implementation across Southeast Asia remains fragmented and often contested.

Environmental Statecraft, Fragmented Authoritarianism, and Technocratic Governance: The Structure and Agency of China's Local Environmental Politics

Environmental Policy and Governance, EarlyView.
ABSTRACT Local environmental politics in China is often said to be dominated by state‐controlled modes of multi‐level governance. However, top‐down governance is embedded within and transformed by local politics, adding complexity to governance practices and environmental outcomes.
