The phrase "already proven efficient" is correct and usable in written English.
It can be used to describe something that has been demonstrated to be effective or successful in the past.
Example: "The new software has already proven efficient in streamlining our workflow and reducing errors."
Alternatives: "demonstrated effectiveness" or "shown to be effective."
This paper presents a computational study of scaled open-hole tensile tests using the Discrete Ply Modeling (DPM) method, which has already proven efficient on both in-plane and out-of-plane loading cases, such as pull through, low velocity impact and compression after impact.
These methods have already proven efficient at suggesting metabolic pathways that account for previously unexplained growth on specific environments [ 48].
We used an organotypic culture system developed in our laboratory that has already proven efficient in assessing the toxicity of ionizing radiation and phthalates (Guerquin et al. 2009; Lambrot et al. 2007, 2009).
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.
The novelty of the approach, which has already been proven efficient for bulk materials (e.g. bcc or fcc Fe-based alloys), is to allow for any structure, without restriction to a specific lattice.
VCEs, featured by Virtual Patients (VPs), are advanced, contextualized and simulated learning environments which portray real-life clinical encounters and have already been proven efficient and cost-effective complementary educational tools in healthcare (Cook & Triola [ 9]).
Tags have already proven to be efficient for indexing knowledge implicitly expressed in online scientific papers, most of which are not fully exploited (or even read). .
Magnetofection has already proven to be efficient nonviral transfection method in vitro and in vivo [ 1, 2, 6– 8].
The research community has already proved that efficient cross-layer routing, in particular rate-aware routing, can significantly improve performances.
