It can be used to indicate that something has been demonstrated to be effective or successful in the past.
Example: "The new software has already proved efficient in streamlining our workflow and reducing errors."
Alternatives: "already demonstrated effectiveness" or "already shown to be efficient."
This paper presents a computational study of notched tensile tests (U-notch) using the Discrete Ply Modeling (DPM) method, which has already proved efficient on both in-plane and out-of-plane loading cases, such as pull through, low velocity impact and compression after impact.
To our knowledge, this is the first study to assess potential of a S. aureus vaccine to yield additional MRSA infection reduction in a hospital setting, on top of other preventative measures that already proved efficient.
To our knowledge, there is no previous work to assess the potential of a S. aureus vaccine to yield additional MRSA infection reduction in a hospital setting, on top of other preventative measures that already proved efficient.
