Therefore, we analyzed trajectories for (1) scale-free characteristics, (2) correspondence with μ = 2 Lévy flights, and (3) persistence of turning direction and intermittency of the search and relocation phases.
There may or may not be a preferred spatial direction, correlations in step size, persistence in direction of motion, oscillations in the velocity, etc.
We further analysed the trajectories of the cells to understand whether there was a particular bias to cell motion in terms of directionality and persistence (a continued direction of movement on a cell by cell basis; Figure 4H and Additional file 4: Figure S4D).
Results are presented in terms of wind speed frequency estimates down to very low values, and also the dependence of such conditions on time of day, stability and averaging time, and the persistence of both wind speed and direction over time periods from ten minutes to three hours.
Motivation can be defined as the processes that account for an individual's intensity, direction and persistence of effort toward attaining a goal [ 1].
According to Robbins et al., "Motivation is the process that accounts for an individual's intensity, direction and persistence of effort towards attaining a goal" [ 27].
The process of autoparallelism of direction appears, thus, as the tendency of persistence of the spacetime direction of a free particle whose motion is governed by, what Weyl calls, the guiding field \((F\ ührungsfeld).
Aligned fibers of extracellular matrix (ECM) affect the direction, efficiency, and persistence of migrating cells.
Confidence in personal ability to carry out a behaviour (i.e., self-efficacy) plays a central role in behaviour change and influences the direction, intensity and persistence of the behaviour [ 23].
