Multichannel Wavefield Reconstruction With Physics‐Informed Neural Networks and Transfer Learning

Geophysical Prospecting, Volume 74, Issue 3, March 2026.
ABSTRACT Multi‐component seismic data contain rich information essential for accurate subsurface imaging, but they are often sparse due to acquisition limitations and include noise. Robust interpolation techniques are therefore crucial to reconstruct missing traces and preserve wavefield integrity for reliable analysis and inversion. Thus, we propose a

A Deep Learning‐Based Time Shift Objective Function for Full Waveform Inversion

Geophysical Prospecting, Volume 74, Issue 3, March 2026.
ABSTRACT Full waveform inversion (FWI) is a powerful technique for estimating high‐resolution subsurface velocity models by minimizing the discrepancy between modelled and observed seismic data. However, the oscillatory nature of seismic waveforms makes point‐wise discrepancy measures highly prone to cycle skipping, especially when the initial velocity

Assessment of Vehicle Stability Processes Under Unsteady Flow Conditions

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT The vehicle stability criteria are based on experimental and theoretical studies that do not account for the unsteady nature of floods. The rapid variation of depths and velocities in floods causes an additional hydrodynamic force in the direction of the flow, destabilising a vehicle that would otherwise be safe in steady flow conditions. This

The Americanization of Nigerian English spelling and punctuation

World Englishes, Volume 45, Issue 1, Page 76-95, March 2026.
Abstract Spelling is the most standardized level of language, and prescriptive spelling norms in former British colonies often advocate adherence to British spelling norms which differs from the local linguistic reality. Hence, recent research on the evolution of postcolonial Englishes and the Americanization of Englishes worldwide has questioned the ...

Toral symmetries of collapsed ancient solutions to the homogeneous Ricci flow

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract Collapsed ancient solutions to the homogeneous Ricci flow on compact manifolds occur only on the total space of principal torus bundles. Under an algebraic assumption that guarantees flowing through diagonal metrics and a tameness assumption on the collapsing directions, we prove that such solutions have additional symmetries, that is, they ...
