The phrase "a key proof of" is correct and usable in written English.
It can be used when discussing evidence or arguments that support a particular claim or theory.
Example: "The discovery of the ancient artifact serves as a key proof of the civilization's advanced technology."
Alternatives: "a crucial piece of evidence for" or "a significant demonstration of".
This study provides a key proof-of-principle experiment, which opens up avenues to eradicate HIV infection by eliminating latent viral reservoirs via T-cell-specific delivery of an HDAC inhibitor in combination with a protease inhibitor.
These studies provide a key proof-of-principle that the aging process can be targeted to achieve wide-ranging protection against aging-associated physiological decline [ 116, 117].
A key proof technique relies on the notion of Restricted Isometry Property, whose conservatism is not well understood and cannot be applied to nonsmooth problems either (such as those involving 1-norm).
Joint tephrochronological/archaeological research in historic periods has the potential to provide key proof-of-concept case studies for this emerging field.
Taken together these data demonstrate the ability of nanotechnological approaches to provide improved methods for activating latent HIV and provide key proof-of-principle experiments showing how novel delivery systems may enhance future HIV therapy.
One problem that we encountered when we started seriously considering how to address an actual disease in an actual living organism using molecular computing was that many of these initial ideas, such as this one, grew rapidly in complexity (e.g., measured by the number of subprojects that had to be finished before key proof-of-concept experiments are even attempted).
It demonstrates several key proof of concept features that should be standard for chemical data hosting, and can be incorporated into open lab notebook software.
The key proof of Theorem 2.2 is to prove two important inequalities for the following homogeneous wave equation in cylindrical domains.
Still, two out of three first stages recovered is a tremendous achievement, which acts as not only a demonstration of SpaceX's progress when it comes to making sure its boosters can return smoothly from their flights, but also a key new proof of concept regarding Elon Musk's vision of reusable spaceflight.
Triple-signed receipts are much easier to implement and meet the same security guarantees as a decentralized ledger with public key cryptography, proof-of-work, networking and database technology.
