The phrase "addition phase" is correct and usable in written English.
It can be used in contexts related to processes, projects, or stages where something is being added or incorporated.
Example: "During the addition phase of the project, we will integrate the new features into the existing system."
Alternatives: "integration stage" or "inclusion period".
In addition, Phase II has provided additional data to further refine the service model of BIS prior to the commencement of Phase III.
In addition, Phase 3 trials are required to have an independent data-safety-monitoring committee that reviews study outcomes and side effects during the course of the trial to assure participants that the study remains appropriate for their medical condition.
In addition, phase constituent after hydrogenation is analyzed.
In addition, phase mapping for relatively lower deposition samples is presented in Fig. S4.
In addition, phase contrast MR may be used for quantification of pulmonary blood flow [3, 43].
In addition, phase transition of materials involves discontinuities in the first derivatives of free energy with respect to their volume.
In addition, phase-separation (boiling) at these shallow-sea hydrothermal sites can partition seawater into a chloride-rich brine and steam distillate that is low in chloride and enriched in volatile gases such as H2S, CO2, He, and H2[39].
In addition, phase-contrast and electron microscopy analyses demonstrated that Caco-2/15 cells containing a low level of PTEN failed to acquire a fibroblastic or scattered morphology and retained their capacity to form some cell-cell contacts.
In addition, phase-contrast microscopic observation of the prototrophic mycelia revealed the presence of rows of uninucleate cells disrupting the heterokaryotic association.
In addition, phase-variable expression of two fimbrial major subunit genes, fim2 and fim3, has been attributed to variations in HPTs located within the promoter regions of these genes that lead to altered transcript abundance [ 26, 27].
In addition, phases are well superimposed onto those of AtCCA1 and AtLHY with peaks close to dawn.
