Contributed data should be derived experimentally and should be accompanied with experimental evidence.

The plot is derived experimentally.

In the second step, error is added to the synthetic patterns using an experimentally derived error distribution.

This equation is only an approximation, and should be used only when no better, experimentally derived formula is known for a given gas.

Like many other database that store protein association knowledge STRING imports data from experimentally derived protein-protein interactions through literature curation.

Byerlee's law is an experimentally derived law in physics that gives the stress circumstances in the Earth's crust at which fracturing along a geological fault takes place.

The two polyadenylation sites within exon 20 are used at roughly equal frequencies, both in experimentally derived clones and public EST sequences corresponding to SLC4A9.

Some threshold levels can be derived experimentally based on the equipment's known signal-to-noise ratios, or a threshold can be defined to match published data or the manufacturer specifications.

This value was first experimentally derived from the resting oxygen consumption of a particular subject (a healthy 40-year-old, 70 kg man) and must therefore be treated as a convention.

While the order of a reaction is derived experimentally, the molecularity is a theoretical concept and can only be applied to elementary reactions.
