The G-proteins' role in signal transmission in the cell is a perfect example of this principle of variations on a theme which achieve the diversity necessary to maintain life.
The governing equations as well as boundary conditions are derived from the principle of variations applied to unified formulation of plate bending with assuming the assumptions of the classical thin plate bending theory (Kirchhoff-Love theory) and/or the shear deformation plate theory of the 1st and 3rd order (FSDPT and TSDPT).
Embracing the constraints and principles of variation, environment, evolution, and ecology.
Making use of these inductive frameworks, Darwin restructured our understanding of life based on the first principles of variation, survival, and reproduction to generate his theory of evolution by natural selection.
Using in silico evolution, we can apply the principles of variation and natural selection to a mathematical model, and evolve "organisms" with parameters that are particularly good at solving a set task (e.g. to minimize the noise of protein expression).
The principle source of variation is the G+C vs. A+T content of codon third positions, which is in turn dictated by large scale genomic organization into G+C rich and light isochores [12], [13].
RW response has been identified as a principle cause of variation in enzymatic saccharification yields in willow, yet understanding of the tissue architectural and cellular remodelling associated with RW has typically been limited to classical sectioning and microscopy.
Charles Darwin's originality lay in his giving precision to the theory of evolution and extinction by reference to the principle of miniscule variation from generation to generation, with variations that gave the slightest edge in reproduction retained.
There is, if not an actual mathematical sequence of changes, at least a principle of incessant variation underlying the whole corpus.
Darwin's theory of natural selection expunged purpose from the history of life by the principle of blind variation and selective retention.
