In science:

In this paper we consider particles diffusing along the edges of a random graph and develop a method for calculating diffusion on a random graph using an algorithm that counts all the paths.
Anomalous diffusion on random graphs
We take D and D0 to be diffusion coefficients for particles of a specified energy as opposed to diffusion coeffi cients of a particle that diffuses in energy as well as space.
Thermal conduction and particle transport in strong MHD turbulence, with application to galaxy-cluster plasmas
This process is indicating subdiffusion: D ≡ lim called double diffusion: the particle diffuses along the fie ld line, and the field line itself is a randomwalk path through space.
Thermal conduction and particle transport in strong MHD turbulence, with application to galaxy-cluster plasmas
For mono-energetic electrons subject to a fixed Coulomb pitc h-angle scattering frequency, the diffusion coefficient Dk,0 for motion along a uniform magnetic field is equal to the three dimensional diffusion coefficient D0 for motion in a non-magnetized plasma.
Thermal conduction and particle transport in strong MHD turbulence, with application to galaxy-cluster plasmas
Let us recall that the horizontal turbulence, expressed by a diffusion coefficient Dh , tends to reduce the shear mixing in regions of steep µ–gradients, making the diffusion coefficient Dshear proportional to Dh rather than to K , the thermal diffusivity.

The relaxation time scale is then given by the spin diffusion time tdif f ∼ L2 /D (where L ∼ 2pkB T /mω2 ax is the size of the cloud and D = kB T τ /m is the spin diffusion constant).

The free diffusion on the d-dimensional phase space is described by a diffusion kernel KD that solves the appropriate free diffusion equation with δ -function initial conditions.

Increasing the harmonic separation R has qualitatively the same effect as decreasing the ribosome diffusivity, since terminated ribosomes now have further to diffuse back to the initiation site.
Ribosome recycling, diffusion, and mRNA loop formation in translational regulation
Steady-state and equilibrium assumptions: Ribosome diffusion and motion along the mRNA are treated within steady state, while the configurational distribution of the mRNA polymer is not directly coupled to ribosome diffusion or motion, and is considered in thermodynamic equilibrium.
Ribosome recycling, diffusion, and mRNA loop formation in translational regulation
Thus, if ribosome recycling via diffusion through the bulk is rate-limiting, the scanning region near the initiation where the linear diffusion occurs can be considered as binding region of larger effective capture radius a.

Such a scaling is standard for diffusive processes and works also very well for matrix-valued diffusion processes studied in and . t is then a real parameter corresponding to ‘diffusive’ evolution time and the continuum limit M → ∞ exists.

Furthermore, Hall diffusion qualitatively changes the vector evolution of the magnetic field, exhibiting a dependence on the strength of the magnetic field and a sensitivity to handedness that breaks many simple planar geometries that could otherwise be maintained in the presence of ambipolar or Ohmic diffusion.
Early Disk Evolution
Top panel shows the case where Hall diffusion is dominant close to the midplane and ambipolar diffusion dominates near the surface.

As an aside, let us remark that a fractional Brownian walk can also be regarded as a diffusion process with ‘time’ τ = N ∆τ and ‘time-increment’ ∆τ (during ∆τ the diffusion spreads out over the step-length lwalk ).
Black Holes, Space-Filling Chains and Random Walks
One learns that the higher-dimensional d > 4 case with dwalk > 2 corresponds to an anomalous diffusion coefficient, i.e. one with non-trivial ‘time’ τ dependence, while the 4-dimensional d = 4 case with dwalk = 2 is distinguished by a truly constant τ independent diffusion coefficient.
