The phrase "a previous study assuming" is correct and usable in written English.
It can be used when referring to a prior research work that is based on certain assumptions or hypotheses.
Example: "In our analysis, we build upon a previous study assuming that the economic factors significantly influence consumer behavior."
Alternatives: "an earlier study positing" or "a prior study suggesting".
This slip distribution is very similar to that of our previous study assuming a northwest-dipping F1 segment (Irikura et al. 2017).
The evaporator model employed in the previous study assumed constant thermal resistances that were obtained from one specific 'size' of the evaporator.
This validates a number of previous studies assuming that pavement cell shape depends on mechanical heterogeneities (Fu et al., 2005), albeit relying only on MT behavior, and further supports plant tissues as facile systems to investigate the relation between the biophysics of growth and development.
The present work considers such a distribution of transmission speeds and extends previous studies assuming a single speed only [13, 30, 37, 38, 46].
Previous studies assuming a global molecular clock have suggested that the Bacillariophyceae clade evolved in the Early Cretaceous (approx. 135 Ma) and as early as in the Middle Triassic (approx 240 Ma; [29], [69], [70]).
The sample size required for the study was calculated using Sample Power software (SPSS ver. 2.0; SPSS, Chicago, IL) based on data from our previous studies, assuming 80% power and a significance level of 0.05.
Based on previous studies, assuming mean changes in slope of 2.3 ± 1.3 for the SHOCK group and 3.2 ± 1.4 for the SEPSIS group, with a power of 90% and Cronbach's α set at 0.05, we calculated that approximately 60 patients per group were needed [ 11].
Actually, this would be not entirely true if lag time between the drug use onset and first treatment followed a determined pattern, as previous studies assumed [ 1, 6].
Additionally, previous studies assumed a time-constant rate of invasion that was the time average of invasion rate.
Fourthly, the genus Koerneria, which was in close relationship to Pristionchus in previous studies, assumes a basal position to all diplogastrid nematodes in this molecular analysis [ 19, 20].
