The phrase "assumed a source" is correct and usable in written English.
It can be used when discussing the act of taking something for granted or accepting it as true without verification, particularly in the context of information or data.
Example: "In her research, she assumed a source of information that later turned out to be unreliable."
Alternatives: "took for granted a source" or "presumed a source".
The laboratory experiments indicate that at this depth an integration time no less than 348 s (falling to 93.9 s at full penetration) would be required to measure a bulk density of 1000 kg m−3 to 5% accuracy, assuming a source activity of 1.48 mCi (decayed from an initial 2 mCi).
For the virtual middle-size earthquake, we assume a source fault with a size 2 km by 2 km, and a seismic moment.
Fig. 9 Variation of probe current with probe size for uncorrected, third- and fifth-order-corrected 300 kV microscopes assuming a source brightness of 3 × 10 9 A sr−1 cm−2.
We assume a source rupture area of approximately 480 km by 200 km over the subducting Pacific Plate as shown in Fig. 2(a), which is divided into 4×3 subfaults with lengths of 160 180 km and widths of 50 km.
Then, for each subsequent time window (jtim), sums of the squared amplitude stacks of the waveforms, S jgrid, jtim), are calculated, assuming a source at each grid point (jgrid), with the following equation.
We also assume a source model (Model C) that does not include the Gifu-Ichinomiya fault in order to confirm that the distribution of seismic intensities of 7 could not be reproduced by that simulation.
Similarly, assuming a source population with 9 or 20 sex-determining alleles, the range expected of natural hymenopteran populations [27], and since females must be heterozygous at the sex-determination locus, a founder population of more than one female would almost certainly have carried more alleles than are now observed in NA (Figure 1B).
Although the ascending gases might generate volcanic tremor simultaneously with descending sources, they may not be detected in our analysis because we assumed a point source in the ASL method (Eq. 1).
While the current simulations assumed a line source of oxygen, the above measurements were performed in vivo and thus oxygen could come from multiple sources.
For the estimate, I assumed a point source.
