In such contexts, diffusin is contrasted with directed transport mechanisms such as advection or drift. A diffusin
Etymology and terminology: the form diffuusin appears to derive from diffuus, the Dutch or Scandinavian word
Applications in models: in classroom simulations or conceptual papers, a diffusin coefficient can be introduced to
Relation to established concepts: in real systems diffusion is described by Fick's laws using a diffusion coefficient
