Surrogate Computational Homogenization Enhanced by Partition‐of‐Unity RBF Interpolation With Decision Trees

International Journal for Numerical Methods in Engineering, Volume 127, Issue 20, 30 October 2026.
ABSTRACT This study enhances a framework of surrogate computational homogenization (SCH) using decision tree‐based partition‐of‐unity radial basis function (PU‐RBF) interpolation for three‐dimensional finite‐deformation two‐scale analysis. The method addresses the scalability limitation of global RBF interpolation for large numerical material test (NMT)

Tidal Variability in the Lower Thermosphere: Relative Importance of ENSO, QBO, PJO, MJO, and Lyα

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric tides in the lower thermosphere play an important role in regulating upper‐atmospheric conditions relevant to space weather. However, their spatial and temporal variability remains poorly understood, apart from seasonal variations. Previous studies have shown that tides can be influenced by meteorological and solar conditions. This

Apportioning Sources of Nitrogen Oxides in California's San Joaquin Valley Using Observations From Three Airborne Field Campaigns

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Emissions of nitrogen oxides (NOx = NO + NO2), a precursor to ozone and secondary aerosol formation have become increasingly important to understand as ozone production transitions to NOx limited in most regions of the US. Recent studies suggest that NOx emissions associated with agricultural activities, particularly cropland soils, are an ...

Ultra‐Weak Photon Emission as a By‐Product of Mitochondrial Oxidative Metabolism: Mechanisms, Limits, and Implications

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...
