Molecular Ecology, Volume 35, Issue 8, April 2026.ABSTRACT Understanding how dispersal, life history, and environmental variability shape genetic connectivity in the open ocean remains a central challenge in evolutionary biology. Highly migratory marine predators like tunas have traditionally been considered genetically homogeneous across ocean basins, yet emerging genomic evidence suggests that ...

Crack Propagation in Tooth Root: A Comparison Between Pulsator Test and Running Gears
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 12, Page 5181-5194, December 2025.ABSTRACT Tooth root fatigue fracture is a critical gear failure mode in which the tooth root breaks because of the repetition of bending load. The most widely adopted procedure for evaluating root strength is through pulsator testing. However, this test method does not present gears in meshing conditions. When focusing on the limited‐life region of the
