Figure 12d shows an RT RMC supercell with the positive (red) and negative (blue) atoms representing the sum of Bi displacements in opposite directions along ⟨11̅0⟩p; groups of atoms gathering in clusters are clearly present indicating the local correlations between Bi atom displacements.
The commensurate HT structure contains two clouds of bismuth atoms displaced in opposite directions, which confirms the simple antiferroelectric displacement character of the A site cations in this commensurate structure.
By contrast, small (less than 5 mm) displacements in the opposite direction occur at the sites far from the epicenter.
Meanwhile, the 2011 Tohoku earthquake produced displacements in the opposite directions, approximately 1.2 mm to the east and 0.5 mm to the north, in the same region.
Thus, in h-BN, the most probable surface reconstruction is the displacement of different atoms in opposite directions from the surface hexagonal layer.
The pair of inertial forces traveling in opposite directions causes displacements and stresses more than twice as large as their corresponding quantities observed for the passage of a single mass.
A frequency sweep in opposite directions results in displacement of the focal plane in opposite directions.
For laterally flexible systems, CD on same side of CR and near to CM, leads to higher reduction in edge accelerations, whereas, locating CD at the extreme distance from CM on the side of CR leads to higher reduction in stiff edge displacement and opposite for flexible edge displacement.
The plot of ankle markers tracking anterior-posterior displacements indicated that the legs were moving in opposite directions, as during fore-aft foot trajectories while walking.
It is notable that a clear displacement discontinuity, across which the ground movement was in opposite direction, can be identified in the northeastern area (Figures 2a and 3a).
