The usual explanation for why the producers of a given product use different technologies involves "vintage-capital": A firm understands the frontier technology, but can still prefer an older, less efficient technology in which it has made specific physical and human capital investments. This paper develops an alternative.

Light diffusing mechanism of new diffusion phenomena for diffusers with different diffusing patterns
Optical Materials, 2021Abstract In this study, different diffusion agents have been employed for preparing optical diffusers. Compared with their properties, significant differences exist in UV-shielding, near infrared shielding, dispersion, light scattering, and etc. The characterization comparison can be found in the testing.

Diffusion time dependency of extracellular diffusion
Magnetic Resonance in Medicine, 2023PurposeTo quantify the variations of the power‐law dependences on diffusion time t or gradient frequency of extracellular water diffusion measured by diffusion MRI (dMRI).MethodsModel cellular systems containing only extracellular water were used to investigate the dependence of , the extracellular diffusion coefficient.

Diffusion, Cross-diffusion and Competitive Interaction
Journal of Mathematical Biology, 2006The cross-diffusion competition systems were introduced by Shigesada et al. [J. Theor. Biol. 79, 83-99 (1979)] to describe the population pressure by other species. In this paper, introducing the densities of the active individuals and the less active ones, we show that the cross-diffusion competition system can be approximated by the reaction ...
