The female reproductive tract is a muscular system, in which contractions are linked to movement of the eggs down the tract from ovarioles via the oviducts to the uterus and finally oviposition of the fertilised eggs.
There is typically a trade-off between ontology and ideology to use the terminology favored by Quine in which contraction in one domain requires expansion in the other.
Geraghty [16] introduced an extension of the Banach contraction principle in which the contraction constant was replaced by a function having some specified properties.
Bruxism is a parafunction in which the contraction of the temporal and masseter muscles is responsible for clenching of the dental arches, while the contraction of the pterygoid muscles is responsible for lateral movements, potentially affecting the temporomandibular joints [ 34].
FitzGerald and Lorentz attempted to preserve the classical concepts by demonstrating the manner in which space contraction of the measuring apparatus would reduce the apparent constancy of the speed of light to the status of an experimental artifact.
As Brad DeLong argues, there's a very good case to be made that we're currently living under conditions in which fiscal contraction actually worsens the long-run deficit.
There are other formal logics in which the contraction rule (from X,X ⊢ A to X ⊢ A) is absent.
Similar patterns were found in the reproductive tract of female D. melanogaster, in which muscle contraction genes were up-regulated in response to mating [ 38].
The subject stepped on 0.5 m high platform with his left leg, that is, the leg in which muscle contraction force was not tested.
