A Detailed and Comprehensive Account of Fractional Physics‐Informed Neural Networks: From Implementation to Efficiency

open access: yesArtificial Intelligence for Engineering, Volume 2, Issue 3, Page 251-264, September 2026.
Caputo‐based fPINNs accurately solve fractional ODEs and PDEs while exposing an accuracy–cost trade‐off driven by the history‐dependent fractional derivative. Temporal collocation and shorter time windows are the most effective strategies for improving early‐time accuracy without unnecessary spatial refinement.

New Acoustic Pure P‐ and S‐Wave Equations for Modelling and Reverse Time Migration in Tilted Transversely Isotropic Media

open access: yesGeophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT To reduce information loss in seismic imaging of complex geological media, it is essential to account for anisotropy, particularly in tilted transversely isotropic (TTI) formations–the most common anisotropy in exploration geophysics. However, the elastic wave equations governing such media inherently couple P$P$‐ and S$S$‐waves, whereas ...

Not all Temperature Shocks are Alike: Disentangling Heat and High Temperature Shocks and Their Effects on Inflation in Australia

open access: yesEconomic Record, Volume 102, Issue 338, Page 323-349, September 2026.
We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Output Quality, Productivity, and Demand: Evidence from the Chinese Steel Industry

open access: yesThe RAND Journal of Economics, Volume 57, Issue 3, Page 784-807, Autumn (Fall) 2026.
ABSTRACT Unobserved objective output quality complicates the analysis of firm productivity and demand because higher‐quality products entail higher costs but offer greater consumption benefits. Using a panel of firms with output quality data, we decompose quantity‐based productivity into fundamental productivity and the costs of quality, and separate ...

Addressing Bias in Non‐Probability Fisheries Surveys Using Multilevel Regression and Poststratification Approaches

open access: yesFish and Fisheries, Volume 27, Issue 5, Page 1088-1106, September 2026.
ABSTRACT Quantifying harvest of fish stocks is challenging as census data are often unavailable, so surveys are required. Traditional probability‐based surveys use random sampling to obtain representative data that can be scaled to estimate total impact.

Chest Circumference, Stature and Body Mass Index as Determinants of 1918 Influenza Severity

open access: yesInfluenza and Other Respiratory Viruses, Volume 20, Issue 9, September 2026.
ABSTRACT Background Anthropometric traits are established determinants of chronic disease, yet their role in shaping infectious disease outcomes during historical pandemics remains underexplored. During the 2009 H1N1 influenza pandemic, obesity emerged as a novel, independent risk factor for severe illness, raising questions about whether physique and ...
