Although the existing time synchronization protocols in wireless sensor networks (WSNs) are efficient for short periods, many applications require long-term synchronization among the nodes, for example, coordinated sleep and wakeup modes, and synchronized sampling.
For this reason, the PSR will be used here to investigate the relations between the SSA, NC, and PG, on short and long timescales, and to characterize long-term synchronization between these variables.
When the periodic vortex-shedding frequency of a bluff structure "locks-in" with one of the natural frequencies of the structure, the state is termed synchronization.
Cross-correlation estimates of long-term synchronization in Fig. 4 were calculated from 0.5 s before the increase of thumb force to the end of force production.
In proof-of-concept studies, stem-cell therapy eliminates contractile deficit originating from infarcted regions and secures long-term synchronization with tissue repair.
In this way, many different types of short-term synchronization between heartbeat and respiration could be shown in individual subjects under experimental resting conditions [ 3, 4, 8, 9, 12, 13, 15, 18].
Weisz et al [ 29] have recently proposed an Oscillatory Model of Tinnitus (now termed synchronization by inhibition modulation; SIM), in which a conceptual link was established between the three frequency bands (delta, alpha, and gamma) in the context of tinnitus.
In general, there are two kinds of impulse in terms of synchronization in complex dynamical networks: desynchronizing impulse and synchronizing impulse [22].
The results also show that the mechanism exhibits encouraging performance in terms of synchronization efficiency and scalability.
