The term ‘diffusion’ denotes random thermal motion of water molecules. In other words, DTI uses the diffusion of water as a probe to determine the anatomy of a brain network, which basically ...

This motion results from the constant, random bombardment of the suspended particles by the molecules of the surrounding fluid. Initially, Brown noted the jittery motion of pollen grains in water and ...

Researchers have shown that turbulence, random motion that takes place in the molten metal in the Earth's core, makes a contribution to our planet's magnetic field. To obtain this result ...

Regular OSCILLATION, for instance, by a particle in a solid, fluid or gas, displaced from its normal position or random motion, when the force required is proportional to the displacement. This motion ...
