The second method is by following a specific attractor to obtain its behavior at long term.
To further determine the biological functions of attractor modules, GO analysis was conducted based on DAVID.
In order to consider the global attractor for the system (1.1)-(1.2) in [H.sup.k] space, we introduce the definition as follows:
Various types of dynamic stability were identified, such as strange attractors (1995.2-1996.1), limit cycles (1996.2-1996.9) and also a combined stable state, which is a set of a fixed stable point, limit cycle and strange attractor (1995.1).
For each attractor generated by the software the fractal dimension (1) was calculated through the superposition of the grids called Kp (5 beats per minute) and Kg (10 beats per minute), the number of occupied squares was quantified for each attractor with the simplified method of Box-Counting (2).
As shown in Table 5, the computation time of the LPA algorithm is least, followed by the Louvain algorithm, then InfoMap, Attractor, and E-Attractor are next and have very similar times; FastGreedy is slowest.
In [12] we have shown that the Planck mass coincides with the main attractor node [44; to] of the F (1) calibrated on the proton:
So, in Section 2, we establish a new abstract theorem on a backward compact pullback attractor for a decomposable evolution process; that is, it has a backward compact-decay decomposition.
Then [phi] has a unique D-random attractor [{K([omega])}.sub.[omega][member of][OMEGA]] which is given by
Note that the changes in the influence field are local because they are confined to tiles under the influence of a given repulsor (resp., attractor).
For b = 3.185, system (1a), (1b), and (1c) can exhibit either one-scroll chaotic attractor or period-6-oscillations depending on initial conditions as shown in Figure 6(a), while, in Figure 6(b) for b = 3.189, system (1a), (1b), and (1c) can exhibit either one-scroll chaotic attractor or period-3oscillations depending on initial conditions.
Self-excited attractors are connected with unstable equilibriums, but a hidden attractor is not connected with equilibria, for instance, those in the systems without equilibria or only one stable equilibrium [28, 29].
