The phrase "a pair of orientations" is correct and usable in written English.
It can be used when referring to two different perspectives, directions, or approaches regarding a particular subject or situation.
Example: "In our discussion, we explored a pair of orientations towards climate change: one focusing on mitigation and the other on adaptation."
Alternatives: "two perspectives" or "a duo of viewpoints".
The output of the pipeline consisted of a pair of orientation counts (s, a), for each genome and for each IS family, describing the number of IS elements presenting either of the two possible orientations.
The fundamental domain of this tiling of the cortical plane is the hypercolumn, which contains two sets of orientation preferences θ ∈ [0, π) per eye, organised around a pair of orientation singularities or pinwheels [ 37].
To exploit the fact that neurons respond maximally at their preferred orientations and minimally at orientations orthogonal to their preferred orientations (Hubel and Wiesel 1962, 1968), we adopted the differential analysis method by introducing a pair of stimulation conditions whose orientations are orthogonal to each other.
He makes discoveries about site geometry, finding underlying principles of numbers and harmony - at one point he sits up till dawn with a map and a pair of spills, measuring the orientation of the Isfahan mosques.
A sound designer proposed several non-speech sound signals based on two schemas: a pair of sounds for the orientation and confirmation functions, and a timeline sequence for the remaining distance.
The appearance of (002) diffractions as a pair of arcs indicates some orientation of the (002) planes occurring in the carbon tubes [29].
In other words, if you entangle a pair of spins that have opposite orientations, and measure one of them as being "up", the other instantly becomes "down", no matter how far away it is.
The beam's launch angles can be continuously varied with the optimized scanning range of over 30° in poloidal direction and ±25° in toroidal, as well as the polarization will be adjusted during the discharge by the orientations of a pair of polarizers in the transmission line to maintain the highest absorption for different operational scenarios.
On the remaining 25% of trials, a pair of gratings with the orthogonal (unexpected) orientation would be presented (Fig. 1C).
Changes in the electronic structure can lead to a change in the intensity or wavelength of light absorption or emission, while changes in the molecular structure can alter the distance or orientation between a pair of fluorophores that serve as a donor acceptor pair.
To test whether IS elements were distributed randomly in the pair of orientation classes, counts were contrasted against a random binomial distribution with P = 0.5 and a two-tailed P value was calculated (supplementary table S3, Supplementary Material online).
