The original macroscopic descriptions were reviewed to ensure that the available slides represented an adequate sampling of significant pathology.

This is left unspecified by the macroscopic description.

He works on asymptotic analysis which includes the study of hydrodynamic regimes and homogenization theory, establishing relation between microscopic and macroscopic description.

It uses and extends concepts from thermodynamics and develops other macroscopic descriptions of complex systems.

This then allows for a macroscopic description expressed as electric permittivity and magnetic permeability.

It assumes in particular that the initial macroscopic description contains all of the information relevant to predicting the later macroscopic state.

For example, if a gas is sloshing around in its container, even a macroscopic description would have to include, e.g., the velocity of the fluid at each different point.

Like other fields in theoretical ecology, it uses and extends concepts from thermodynamics and develops other macroscopic descriptions of complex systems.

The plain term 'thermodynamics' refers to macroscopic description of bodies and processes.

If you have thousands of photons, these flutuations in effect cancels out so we have a stable macroscopic description like classical physics.
