We show that for the symmetric simple exclusion process on Zd the self-diffusion coefficient of a tagged particle is stable when approximated by simple exclusion processes on large periodic lattices.

When light is scattered from a solution or a suspension, it undergoes random changes in intensity. This phenomenon helps us to determine the size of the particles that scatter the light. This is the ...

There are many industrial suppliers who specialize in, and sell, particle size analyzers to laboratories. Whilst we’re not going to focus on the individual companies (or their specific instrument), we ...
