Direct observation of substitutional and interstitial dopant diffusion in oxide grain boundary [PDF]
Nature CommunicationsGrain boundaries (GBs) serve as fast diffusion paths for dopant atoms, and the segregated dopants can significantly alter the materials’ properties. However, the exact mechanism of fast dopant diffusion along the GBs, particularly at atomic scale, is ...

Information filtering by similarity-preferential diffusion processes [PDF]
EPL (Europhysics Letters), 2014 Recommender systems provide a promising way to address the information overload problem which is common in online systems. Based on past user preferences, a recommender system can find items that are likely to be relevant to a given user. Two classical physical processes, mass diffusion and heat conduction, have been used to design recommendation ...

Value certainty in drift-diffusion models of preferential choice. [PDF]
Psychological Review, 2020 AbstractThedrift-diffusion model(DDM) is widely used and broadly accepted for its ability to account for binary choices (in both the perceptual and preferential domains) and response times (RT), as a function of the stimulus or the choice alternative (or option) values.

Fluid-mechanical structure of methane-air and propane-air turbulent premixed flames
Nihon Kikai Gakkai ronbunshu, 2015 The flow fields of lean and rich propane-air and methane-air turbulent premixed flames of the identical conditions of laminar burning velocity and characteristic of turbulence have been closely examined by using a three-color six-beam LDV system.

Quantitative experimental monitoring of molecular diffusion in clay with positron emission tomography [PDF]
Solid Earth, 2016 Clay plays a prominent role as barrier material in the geosphere. The small particle sizes cause extremely small pore sizes and induce low permeability and high sorption capacity.

Hydrogen-enriched nonpremixed jet flames: Effects of preferential diffusion
International Journal of Hydrogen Energy, 2013 Influence of preferential diffusion on the dynamics of hydrogen and syngas nonpremixed impinging jet flames was studied using direct numerical simulation and flamelet generated manifolds based on detailed chemical kinetics. The results presented in this study were obtained from a uniform Cartesian grid with 768 × 768 × 768 points.
