Among his results, Gauss showed that under a paraxial approximation an optical system can be characterized by its cardinal points and he derived the Gaussian lens formula.

The classic population of brown fat cells and muscle cells both seem to be derived from the same population of stem cells in the mesoderm, paraxial mesoderm.
43.
The interaction with ectoderm and somite-forming morphogenic factors cause some primary mesenchyme to form neural mesenchyme, or paraxial mesoderm, and contribute to somite formation.
44.
Is a solution to the paraxial wave equation ( see paraxial approximation, and the Fourier optics article for the actual equation ) consisting of the Bessel function.
45.
Is a solution to the paraxial wave equation ( see paraxial approximation, and the Fourier optics article for the actual equation ) consisting of the Bessel function.
46.
The shape of the laser beam depends on the type of resonator : The beam produced by stable, paraxial resonators can be well modeled by a Gaussian beam.
47.
Somites are bilaterally paired blocks of paraxial mesoderm that form along the head-to-tail axis of the developing embryo in skin ( of the back ).
48.
Paraxial mesoderm surrounding the notochord at the sides will develop into the somites ( future muscles, bones, and contributes to the formation of limbs of the vertebrate ).
49.
The paraxial form of the Helmholtz equation is found by substituting the above-stated expression for the complex amplitude into the general form of the Helmholtz equation as follows:

A more interesting example of OAM is the internal OAM appearing when a paraxial light beam is in a so-called " " helical mode " ".
