The phrase "altered by low" is not correct and does not convey a clear meaning in written English.
It may be intended to describe something that has been changed or modified due to low conditions, but without additional context, it is ambiguous.
Example: "The image was altered by low lighting, resulting in a grainy appearance."
Alternatives: "modified by low" or "changed due to low".
We found that the electric polarizability of Fe3O4 nanoparticles is altered by low-intensity visible radiation (I ≤ 0.2 kW/cm2; λ = 442 and 561 nm) and reaches a value of 107 Å3.
However, the consistent insulin concentrations across all groups during the euglycemic clamp studies suggest that insulin clearance is not altered by low-dose GC administration.
The data presented here therefore demonstrate that echolocation behavior in horseshoe bats is also significantly altered by low-frequency noise ranging from 10 to 30 kHz, thus masking frequencies far below the range relevant for echolocation.
The amplitude behavior may be altered by adding low order terms to Eq. (21).
Because of the cultural noise present on these measurements, the real value of the skew at those sites and frequencies is uncertain, as it could be altered by the low quality of the data.
Ten proteins involved in protein folding and chaperoning were found to be altered by the low protein diet in proteomic analysis [18] and data provided by microarray analysis are congruent with an increased sensitivity to oxidative stress in islets from LP fetuses [19].
There is emerging evidence that the growth of cancer cells may be altered by very low levels of electromagnetic fields modulated at specific frequencies.
Citrate synthase (CS) activity was not altered by the low or medium doses of nitrate, but was 2.9-fold higher in rats receiving high-dose nitrate supplementation compared with controls (Fig. 2c).
Of these, the NOS3 gene was indicated as having a role in regulating vascular tone and blood vessel diameter, which may be altered by the low-oxygen environment of Tibet.
