"operational proof" is correct and usable in written English.
It is typically used to refer to a demonstration of how something works or is done. For example, "The operational proof of the algorithm showed that it worked correctly and efficiently."
In conclusion, although we recognize that, by a strictly semantic definition, the term "confirmed" should be reserved for cases for which there is a parasitological proof, in operational terms, we could not rely on a direct test that has such a poor sensitivity in this particular patient population.
Vostok also uses a closed operational node set and Proof-of-Stake.
On the other hand, it will be essential to present rigid proof of reliable operational experience to develop proper understanding of the safety features of new reactor systems among the people around the demonstration plant sites.
Although PK-resistance is widely accepted as a standard operational rule for prion identification, the decisive proof of infectivity is the biological assay, based on the appearance of TSE-recapitulating neurologic syndromes in animals inoculated with alleged prion-tainted materials.
In this section, we present the proofs of constructions of four new operational matrices.
The formal semantics of the language is defined by a proof-theoretic calculus, and for the operational mechanism we use a stratified fixpoint semantics, which is proved to be sound and complete w.r.t. the former.
Officials have said Mr. Awlaki's role went beyond inspiration into operational planning of attacks, though they have not supplied proof of that.
Still, she cautions, the nano vacuum tube is more of a "proof of concept" than a working device, since its operational requirements do not yet match modern transistors.
Flake said the border requirements in the framework should not be interpreted as an attempt to block or delay visas to immigrants, particularly because there's already proof in Arizona that the border can get to operational security.
The 2004 draft of the Guide to ship sanitation of the World Health Organization includes aspects regarding design, construction and operational control measures for insects and rodents, as well as rat proof construction.
