"narrow divergence" is a correct phrase which can be used in written English.
It is typically used when describing a situation in which two things have very slight differences. For example: "The two candidates had virtually identical platforms, with only a narrow divergence on economic policy."
By simulating the electrical field distribution above the CNF, we concluded that the optimum values of the electro-optical properties of CNFs on the tip substrate were found at an angle of approximately 50º with a narrow divergence angle.
Photonic crystal vertical emitting QCLs were designed to produce vertical radiation from rectangle aperture (200 μm × 200 μm) with narrow divergence angle of 2.4° × 1.8° [2].
Whereas diffuse OW links emit light over a large divergence angle, the MSD transmitter uses a series of narrow divergence beams directed to the ceiling.
Relationships with narrow divergence time intervals received unexpectedly limited support even from the phylogenomic analyses.
The estimated trait range through time showed an initial period of narrow divergence, followed by a marked increase in trait ranges associated with the accelerated evolution of flower size within the clade Nematanthus-A (Fig. 2a).
This is particularly true when narrow divergences are required such as for long-range applications.
Therefore, speciation adds an additional level of complication for resolving such narrow divergences.
It is generally expected that increasing the amount of data and improving the taxon sampling enhance the resolution of narrow divergences.
sinensis beta-keratins were found in both subclades, we were able to further narrow the divergence time to at least 160 Ma, which suggests that this duplication happened early in turtle evolution.
Narrowing this divergence will require the rejection of an economic model built around fossil fuels that thrives on the promotion of relentless consumption by underpricing resources and externalizing true costs.
Our study shows that complete mitochondrial genome sequences are more effective to reconstruct robust phylogenies and to narrow down estimated divergence time intervals than only short portions of the mitochondrial genome, although there are also limitations in resolving phylogenetic relationships.
