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].
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 appearance of (002) diffractions as a pair of arcs indicates some orientation of the (002) planes occurring in the carbon tubes [29].
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.
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.
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).
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.
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.
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.
As a measure of neuronal discrimination performance, we calculated the neurons' capacity to discriminate between each combination pair of test orientations (d', Green and Swets, 1966), calculated by dividing the absolute difference between the neurons' mean firing rates by the rms standard deviation).
This motif is reminiscent of a cis-regulatory motif recently identified in the regulatory regions of Drosophila immune response genes which consists of a heterotypic pair of REL and GATA binding sites with a defined orientation relative to each other [48].
