Reassessing Alpine Permafrost Thermal State by Accounting for Ground Ice

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Permafrost thermal state, representing the stored “cold energy” in the ground, is crucial for assessing permafrost changes. However, the conventional metric, mean annual ground temperature (MAGT), has inherent limitations because it overlooks the thermodynamic contribution of ground ice.

Modeling Transient Flow in Heterogeneous Aquifers With the Mixed Pressure‐Velocity Formulation of Physics Informed Neural Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Physics‐Informed Neural Networks (PINNs) have emerged as a powerful framework for modeling groundwater flow using deep learning neural networks, particularly in scenarios where traditional data‐driven approaches are limited by the scarcity of data.

Learning 2D Shallow Water Equations With Physics‐Informed Neural Operator Networks

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract This study investigates the application of Physics‐Informed Neural Operators (PINOs) for solving the two‐dimensional shallow water equations (2D SWE) in the context of flood modeling. Unlike Physics‐Informed Neural Networks (PINNs), which require retraining for each new initial or boundary condition (BC), PINOs learn the solution operator ...

Heterogeneous Spillover Effects: How FDI in Resources Extraction, Manufacturing, and Services Affect Sectoral Carbon Emissions in the MENA Region

Natural Resources Forum, Volume 50, Issue 3, Page 1299-1319, August 2026.
ABSTRACT The MENA region faces a critical challenge: balancing economic growth spurred by foreign direct investment (FDI) with environmental sustainability. While FDI can bring technological advancements and capital, concerns exist about its potential to exacerbate environmental degradation, particularly carbon emissions.

Climatic Niche Differentiation Accompanied the Radiation of Leaf‐Eared Mice in the Phyllotis darwini Species Group (Sigmodontinae, Cricetidae)

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim To characterise the evolution of climatic niches during the diversification of the Phyllotis darwini species group, in order to assess the extent to which divergences involved in radiation were associated with patterns of conservatism or divergence of climatic niches, and whether the differentiation found among climatic niches correlated ...

Deep Energy Method for Large Deformation Analysis of Isotropic and Inhomogeneous Hyperelastic Ellipsoidal Pressurized Structures

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT The accurate prediction of displacement and stress fields in pressure vessels is essential for the safe and reliable design of these structures, particularly when dealing with nonlinear behavior such as that of hyperelastic functionally graded materials (FGMs).

A Strictly Geostrophic Product of Sea‐Surface Velocities From the SWOT Fast‐Sampling Phase

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract While geostrophy remains the simplest and most practical balance to extract velocity information from sea‐surface height anomaly (SSHa), confusions remain within the oceanographic community to what extent this balance can be applied to altimetric observations with the launch of the Surface Water and Ocean Topography (SWOT) satellite. Given the

Sensitivity of East Asian Meso‐β‐Scale Convective Systems Identification to Microphysical Processes in a Convection‐Permitting Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Mesoscale convective systems (MCSs) are key contributors to heavy rainfall in the East Asian summer monsoon, yet their statistics and internal structure remain difficult to simulate, even in convection‐permitting models (CPMs). This study evaluates the performance of the newly developed Unified Forecast System Double‐Moment microphysics scheme
