The phrase 'has been first applied' is correct and can be used in written English.
This phrase typically appears in the passive voice and is used to describe when a particular idea, practice, or technique has been used for the first time. For example, "The term 'eco-friendly' has been first applied to products that are made with sustainable materials."
This theoretical study has been first applied in a one dimensional approach of the breakdown voltage.
MPC has been first applied to the chemical process industries and now it is also used in microelectronics.
Validated for a simulated nonlinear amplifier, our algorithm has been first applied to a real amplifier (GaN PA polarized in AB-class) for a QPSK-OFDM signal [5].
For the GA, it has been first applied in 1975 by Holland [13] and it is well known in many application fields as a new tool for complex systems optimization.
This analyzer has been first applied in the field of Auger electron spectroscopy, where we demonstrate the capability of fast data acquisition at high vacuum, that in turn can enable applications in semiconductor inspection and in the usual SEM environments.
The proposed new approach has been first applied for calculating the wave crest height exceedance probabilities of sea states with standard JONSWAP spectra corresponding to different water depths, and the calculation results have been favorably validated against Monte Carlo simulation results.
The name Ionia must therefore have been first applied to this coast subsequent to the collapse of the Achaean kingdoms in Greece in the face of the Dorian invasion, when Ionic Greek refugees migrated eastward across the Aegean to Anatolia about 1000 900 bc.
Heme proteins have long been at the forefront of spectroscopic studies due to their structural and electronic characteristics; numerous physical and spectroscopic methods have been first applied to the study of heme proteins over the years.
Recently, a flow photoelectrochemical cell has been first developed and applied to assay global antioxidant capacity in our group.
Laparoscopic surgery has been used extensively since it was first applied in the 1980s.
Since cathodic protection (CP) systems were first applied, engineers have used experience and intensive monitoring to optimise their design to prevent corrosion.
