The phrase "an initial proof" is correct and usable in written English.
It can be used when referring to a preliminary or first version of a proof, often in academic or technical contexts.
Example: "The researchers presented an initial proof of their hypothesis at the conference."
Alternatives: "a preliminary proof" or "a first proof".
This is an initial proof of concept that may have applications in areas where mechanical systems are being measured in quantum limited domains.
A lactic acid yield of 0.358 g/g of lactose was achieved from whey fermentation, providing an initial proof of concept for the production of value-added chemicals from excess industrial whey using engineered yeast.
This paper presents various implementations of the technology, commencing with an initial proof of concept and going on to the use of smart cards to permit remote use of the system and influence the level of perceived confidence among users, eliminating the role of one of the confidence authorities formerly required to ensure appropriate system security.
After an initial proof firing in July 1914 and minor changes, the 16" Mark 1 was re-proved in May 1916 and production approved in January 1917.
As an initial proof of concept, biotinylated lysozyme (biotin-HEL) was used as a model analyte, giving a detection limit as low as 0.1 ng/mL.
An alternative approach consists of the use of minimally invasive, endosonographic procedures to obtain an initial proof of mediastinal nodal involvement.
We also show the results from an initial proof-of-concept prototype developed at LLNL.
This beam will be used in an initial proof-of-principle experiment for the ODR OTR interferometer.
As an initial proof-of-concept experiment, we used LEMONS to investigate the performance of chemical similarity methods given libraries of short polymers of proteinogenic amino acids.
Nonetheless, the ability to distinguish significant differences in [11C]erlotinib uptake between erlotinib-sensitive and erlotinib-resistant tumors using SUVs suggests that a more pronounced difference would have been observed had a kinetic analysis been performed, and provides an initial proof-of-concept prior to the validation by full kinetic analysis.
