Seasonal and Interannual Variability of Antarctic Bottom Water Downstream of the Four Key Formation Regions

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Antarctic Bottom Water (AABW) is a cold, dense water mass formed around Antarctica that ventilates the global abyssal ocean. Recent studies have reported widespread warming, freshening, and thinning of AABW, yet its temporal variability remains poorly constrained because of sparse observations.

Physics‐Informed Machine Learning Framework to Retroactively Estimate Mantle Thermal Convection From Partial Geophysical Observations

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Mantle convection drives the solid Earth, powering plate motions, volcanism, and earthquakes while regulating planetary heat loss. Reconstructing its history is hampered by sparse, noisy observations concentrated near the surface and the present day. Here I develop an inverse physics‐informed neural network framework to estimate mantle thermal

Predicting Coronal Mass Ejection Travel Times Using Enhanced Model‐Guided Machine Learning

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Coronal mass ejections (CMEs) are key drivers of space weather events, posing risks to both space‐borne and ground‐based systems. An accurate prediction of their arrival time at Earth is critical for impact mitigation. To this end, physics‐informed artificial intelligence (AI) approaches have proven more effective than purely data‐driven or ...

Post‐Collisional Evolution in the Southern Variscan Belt: Insights From Numerical Modeling of the Valpelline Series (Western Alps)

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The post‐collisional evolution of orogenic belts is commonly marked by high‐temperature metamorphism and widespread magmatism, yet the processes linking collision to post‐collisional dynamics remain difficult to reconstruct due to limited exposure of deep‐crustal levels and uncertainties in the determination of pressure‐temperature conditions ...

New Ideas in Lagrangian Relaxation for a Scheduling Problem with the weighted Tardiness Criterion

International Journal of Applied Mathematics and Computer Science
We consider an extension of Lagrangian relaxation methods for solving the total weighted tardiness scheduling problem on a single machine. First, we investigate a straightforward relaxation method and decompose it into upper and lower subproblems.

Weinstein neighborhood theorems for stratified subspaces

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract By analogy with Weinstein's neighborhood theorem, we prove a uniqueness result for symplectic neighborhoods of a large family of stratified subspaces. This result generalizes existing constructions, for example, in the search for exotic Lagrangians.
