Preservation and palaeobiogeography of dinosaur eggs from the Dadaepo Formation (Upper Cretaceous: Cenomanian), Korea

open access: yesPapers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Dinosaur eggs were recovered from the Dadaepo Basin in Busan (south‐east Korea), which is early Late Cretaceous in age and is close to Japan, but the eggs have not been studied. Among East Asian egg‐bearing basins, the Dadaepo Basin is characterized by exceptionally high thermal maturity (c.

Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

open access: yessteel research international, Volume 97, Issue 5, Page 2672-2692, May 2026.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Performance of five common soil moisture sensors using default calibration equations in low‐salinity conditions

open access: yesVadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Soil moisture monitoring plays a critical role in water resource management, hydrological modeling, and climate studies, making sensor accuracy and reliability increasingly important. This study evaluates the performance of five soil moisture sensors—the CS655, HydraProbe, TDR‐315N, TEROS 12, and ThetaProbe—using their default calibrations ...

Evolving Fire Frequency in the Western United States and Its Links to Human Influence

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract Burned area and wildfire damages in the western United States (WUS) have increased dramatically in recent decades. Wildfire frequency, however, has shown trends that vary by data set, region, and fire size. Using a comprehensive fire occurrence data set screened for reporting artifacts from 1992 to 2020, we show a significant downward trend in

Continental‐Scale Machine‐Learning Classification of Arctic Glacial Landscapes Using Simple Morphometrics

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Landscapes formed by glacial erosion have previously been classified based on qualitative interpretation of geomorphic evidence, using aerial photography and field studies. In the current era of high‐resolution elevation data, limited attempts have been made to improve these classifications using quantitative measurements of landscape form (i ...

Tridiagonal Symmetries of Models of Nonequilibrium Physics

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We study the boundary symmetries of models of nonequilibrium physics where the steady state behaviour strongly depends on the boundary rates. Within the matrix product state approach to many-body systems the physics is described in terms of matrices ...

Exorcizing Divergence in Tree‐Ring Density Along the Rocky Mountains

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Briffa et al. (1998), https://doi.org/10.1038/35596 published a seminal paper on the reduced sensitivity of annual tree growth to temperature across Northern Hemisphere treeline stands. By averaging tree‐ring chronologies to sub‐continental means, they found decade‐long trends in maximum latewood density (MXD) progressively diverging from ...

Environmental drivers of metapopulation dynamics throughout the full annual cycle in a declining Arctic‐nesting migratory herbivore

open access: yesJournal of Animal Ecology, Volume 95, Issue 5, Page 865-881, May 2026.
We provide a framework for extending commonly used integrated population models to a metapopulation framework for testing novel ecological hypotheses about how changing environmental conditions within and among subpopulations drive changes in animal abundance.
