The classes of anomalous diffusions are classified as follows: α < 1: subdiffusion. This can happen due to crowding or walls. For example, a random walker in a crowded room, or in a maze, is able to move as usual for small random steps, but cannot take large random steps, creating subdiffusion.

Complementary treatments are used in conjunction with proven mainstream treatments. They tend to be pleasant for the patient, not involve substances with any pharmacological effects, inexpensive, and intended to treat side effects rather than to kill cancer cells. [15]
Wilhelm Heinrich Schüßler (also spelled Schuessler; 21 August 1821 – 30 March 1898) was a German medical doctor in Oldenburg who searched for natural remedies and published the results of his experiments in a German homeopathic journal in March 1873, leading to a list of 12 so-called "biochemic cell salts" that remain popular in alternative medicine.

Figure 1. Whole-cell current recordings of K ir 2 inwardly-rectifying potassium channels expressed in an HEK293 cell. (This is a strongly inwardly rectifying current. Downward deflections are inward currents, upward deflections outward currents, and the x-axis is time in seconds.)
In cell biology, diffusion is a main form of transport for necessary materials such as amino acids within cells. [1] Diffusion of solvents, such as water, through a semipermeable membrane is classified as osmosis. Metabolism and respiration rely in part upon diffusion in addition to bulk or active processes.
Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move from a region of high concentration to a region of low ...
Single-wavelength anomalous diffraction (SAD) is a technique used in X-ray crystallography that facilitates the determination of the structure of proteins or other biological macromolecules by allowing the solution of the phase problem.
