Abstract Lumbar intervertebral disc degeneration, a key indicator of aging in the human movement system, is linked to increasing global cases of low back pain. Current diagnostic methods rely on imaging and physician experience, lacking predictive tools and personalized treatment strategies. This study used a multicenter lumbar MRI dataset to map disc degeneration in the Chinese population, revealing three accelerated degeneration phases during the lifecycle.

Epitaxial thin films of tantalum-doped β-Ga2O3 (Ta-Ga2O3) were grown on MgO (001) substrates to study the effect of Ta doping on the electrical properties of β-Ga2O3 films. X-ray diffraction measurements show that the films with different Ta doping concentrations are (00l)-oriented single-crystalline β-Ga2O3 without impurity phases. The incorporation of the Ta element modifies the electrical properties of Ta-Ga2O3 films significantly.
