There now exists a theory of the Strong and Electroweak interactions ("the Standard Model") that has been tested to high accuracy and that explains almost all existing experimental data.
The ontological commitments of a theory are, roughly, what the theory says exists; a theory is ontologically committed to electrons, for example, if the truth of the theory requires that there be electrons.
However, in theory there exists a possibility that the integration of incoming DNA could also follow a non-homologous recombination pathway.
Despite numerous efforts devoted to characterizing the mechanical behavior of such materials, there does not exist a general continuum theory describing the plastic deformation of these materials.
In addition to theories of aging based on molecules and cells, there also exists a "psychosociological" theory of aging.
On the other hand, these spaces have much in common, and there exists a rich theory.
This theorem states that relative to a partition of the vocabulary of an axiomatizable theory T into two classes, t and o (theoretical and observational, say) there exists an axiomatizable theory T* in the language whose only non-logical vocabulary is o, of all and only the consequences of T that are expressible in o alone.
While the incentive structure approach has found its main application in the social and economic integration of immigrants, the opportunity structure approach exists as a theory within the literature on social movements, and has been mainly applied to theorize the political integration of immigrants.
Knowing that humans already exist, any theory can be jiggered to arrive where it needs to arrive.
As the harmonic analysis associated with the Weinstein operator has known remarkable development, it is a natural question whether there exist an equivalent of the theory of localization operators and new uncertainty principles for the continuous wavelet transform relating to this harmonic analysis.
