This influence has been investigated experimentally and can be taken into account by reduction factors.

Stochastic resonance in large-scale physiological systems of neurons (above the single-neuron level but below the behavioral level) has not yet been investigated experimentally.

Up to now the photon structure function has only been investigated experimentally by electron scattering off a beam of quasi-real photons.

His examples included two he had investigated experimentally: slave-making ants and the construction of hexagonal cells by honey bees.

Darwin discussed ways that species could be dispersed across oceans to colonise islands, many of which he had investigated experimentally.

Investigated experimentally by Crawford et.

However, the problem has been extensively investigated both experimentally and theoretically and is well understood (see Johnson and Guet).

The nature of the representations assembled during speech production are investigated experimentally, including measurement of articulatory activity during speech errors.

In this framework quantum gravity, string theory, and black holes may be experimentally investigated at the Large Hadron Collider.

Much later these states were investigated experimentally and termed polaritons.
