The phrase "be solely explained" is correct and usable in written English.
You can use it when something's cause or reason can be attributed to one thing, or can be exclusively attributed to one thing. For example, "The success of the project could be solely explained by the dedication of its members."
The measured strain sensitivity of electrical resistance of individual CNFs could not be solely explained based on strain induced dimensional changes of CNFs, pointing to piezoresistivity in nanofibers.
This uplift rate is higher than total convergence rate across the study area (Additional file 1: Figure S5), which is unrealistic to be solely explained by fault motion.
While experimental kinematics and bone strains closely matched model predictions, observed pelvic fractures did not consistently agree with the model, and could not be solely explained by vehicle geometry.
This indicates that the thermal quenching of sensitized Er3+ PL in SRON is different from that in SRO and cannot be solely explained by thermal emission of the carriers out of a confining potential [11].
Overall we observed considerable bias between instruments with different principles of measurements, which could not be solely explained by uncertainty in the evaluation of the diameters, or by wind effects, indicating that difficulties in the determination of the optical disdrometer's sensing area could be the cause.
From a biomechanical analysis, it can be concluded that the observed nonlinear pressure-volume relation cannot be solely explained by the confinement conferred by the renal capsule, suggesting that above a certain level of intrarenal pressure, tissue recruitment at the kidney periphery occurs in order to sustain higher levels of intrarenal pressure.
But studies of segregated areas have found that the neighborhood composition cannot be solely explained by economics -- there are often areas that have similar economic characteristics but very different racial makeups.
Therefore, restricted inflammation of NMO cannot be solely explained by the pattern of expression of AQP4.
Both, the strong rough eye and the overgrowth phenotype cannot be solely explained for by inhibition of apoptosis.
Therefore, the increase in biological response elicited by the coexpression of ErbB receptors cannot be solely explained by specific protein interactions induced by each receptor.
ASD is the most heritable neuropsychiatric disorder, yet very few cases can be solely explained on the basis of de novo genetic mutations or cytogenetic abnormalities [4].
