Weak Physics‐Guided Multi‐Agent Learning for Surface to Subsurface Moisture Estimation Across Diverse Climate and Soil Conditions

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Estimating subsurface soil moisture remains challenging due to limited in situ observations and the complexity of soil water dynamics. Although surface soil moisture can be retrieved from satellites with high accuracy, deeper layers are not directly observable. Traditional physics‐based models that predict subsurface soil moisture require site‐

A solution procedure for behavior of thick plates on a nonlinear foundation and postbuckling behavior of long plates [PDF]

Approximate solutions for three nonlinear orthotropic plate problems are presented: (1) a thick plate attached to a pad having nonlinear material properties which, in turn, is attached to a substructure which is then deformed; (2) a long plate loaded in ...

AI‐Based Improvement of IRI‐2020 Electron Density Profiles With COSMIC Radio Occultation Data

Space Weather, Volume 24, Issue 2, February 2026.
Abstract In this study, we propose an AI‐based method to improve the electron density profiles generated by the International Reference Ionosphere (IRI)‐2020 model using the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) radio occultation (RO) data.

The HK Index: A Disjointness‐Driven Model for Intelligent Ranking of Scientific Impact

Expert Systems, Volume 43, Issue 2, February 2026.
ABSTRACT Accurately predicting scientific impact and ranking researchers remains a central yet complex challenge in research evaluation. Traditional metrics such as citation counts, publication totals, hybrid measures, and h‐type indices each capture limited aspects of scholarly influence, making it difficult to establish a universally accepted ...

Restoring Balance: The Intersection of Management and Fishing Sustainability in Indonesia

Fisheries Management and Ecology, Volume 33, Issue 1, Page 54-68, February 2026.
ABSTRACT As the world's second‐largest fish producer, Indonesia plays a crucial role in global fishing. However, overfishing, habitat degradation, population growth, and container port traffic threaten the sustainability of the fishing industry. We examined the impacts of fishing, population growth, and container port traffic on Indonesia's fishing ...

Fourier ARDL Modeling of Natural Resources, Productive Capacities, Climate Resilience, and Green Innovations for Ecological Sustainability

Natural Resource Modeling, Volume 39, Issue 1, February 2026.
ABSTRACT This study investigates how natural resources, productive capacities, climate resilience, green innovations, and education influence ecological sustainability in China. Using annual data from 2001 to 2023, we apply the Fourier ADF and Fourier ARDL approaches to capture nonlinear dynamics and smooth structural breaks often missed by traditional

Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles

Advanced Engineering Materials, Volume 28, Issue 2, 21 January 2026.
Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.
