The direction of neurite outgrowth in relation to topographic guidance cues was assessed using the "directionality" plugin in ImageJ (open source software).
[13] demonstrated that whole-hand water flow with single directionality increased corticospinal excitability, whereas whole-hand water immersion did not.
Overlapping directionality between magnitudes squared coherence values and unwrapped phase differences between channels are shown in Figure 3.
The nanoantennas are highly modular, can be "painted" onto any surface or, to preserve the directionality in absorption, can be directly transferred onto virtually any surface.
As observed in Figure 2, image directionality is strongly apparent after the shearlet transform.
To quantify the extent of matrix organization of each sample, directionality histograms were generated using Fiji/ ImageJ.
The basic functions of contourlet transform are multi-scale and multi-dimensional, thus allowing it have multi- resolution, localization, directionality, critical sampling and anisotropy (more on these properties in next section).
"Unidirectional nanoantennas induce directionality to any omnidirectional light emitters like microlasers, nanolasers or spasers, and even quantum dots," said Debabrata Sikdar of Monash University in Victoria, Australia.
In particular, we propose an extended GHT that updates the best matching score and the sum up score simultaneously, combined with a customized face detector and circular magnitude ranker, for detecting Guy Fawkes; we also propose an extended GHT capable of mining the directionality property in Hough space, combined with object character recognition and an edge density filter, for detecting the presence of credit cards in social media images.
Donald Wayne Viney discusses the directionality of Teilhard's conception of evolution.
The design moves between two scales: a building and an industrial heat machine that, according to the project's lead architect, Eliot Postma, "creates a directionality to the structure, with all of the mullions conjoining at this single point of connection, almost as if the glass is being blown from the still building and coming to rest in the river below."--David Basulto, founder and editor-in-chief of the website ArchDaily
Different hypotheses have been offered to explain the directionality effect in simple and double premises: one hypothesis claims that the directional effect is due to the order of the terms in the working memory (FIFO hypothesis) during the integration of the premises.
