Diffusion processes, characterised through operators such as the graph Laplacian, foster the development of diffusion maps which yield robust, multi-scale representations.

In a diffusion graph the x-axis is time, which can be denominated in whatever unit is appropriate. Many of the canonical studies measure time in years, but tetracycline spread in a matter of ...

We study the interplay between the diffusion of a harmful state in a network of contacts and the possibility of individual agents to undertake costly investment to protect themselves against infection ...

"Diffusion tensor MR tractography may function as a novel quantitative tool and marker of treatment response," said study coauthor Jennifer W. Uyeda, MD, Brigham and Women's Hospital.
