Petri nets are a flexible and expressive modeling approach, which allows a general interactions between system components, including synchronization of event firing times.
Over longer periods of time, the lunar cycle provides a light cue that is thought to play a role in synchronization of reproductive events such as gametogenesis, spawning or larval release in some scleractinian coral species [11], [12].
Converging evidence shows that pulse-salient models underlie rhythm formation; these models require synchronization of rhythmic events into felt pulse patterns [16], [17]; these patterns refer to the presence of a temporally equally spaced sequence of auditory events that serve as perceptual reference points to hear sound durations and patterns [18].
An individual plant or particular population could be in more than one phenological state at a given time, depending on the synchronization of reproductive events.
In this context, most studies of tropical reproductive phenology where climate seasonality is not pronounced are basically restricted to submontane and montane rainforest, where climatic factors are not directly responsible for the triggering and synchronization of phenological events (Heideman 1989; Sun et al. 1996; Hamann 2004).
In larger and more complicated organisms those in which response involves the synchronization and integration of events in different parts of the body a control mechanism, or controller, is located between the stimulus and the response.
This shift in the observed dynamics when the observation length scale is decreased is discussed in terms of the synchronization of small-scale events.
Synchronization of these two events requires starting the gradient either before or even after the injection, thus to prevent a late or an early arrival of the gradient front to the injection valve, respectively.
It is possible that these apparent differences in numbers of differentially expressed genes between the two epithelia, reflect more synchronization of regenerative signaling events in the cochlea when compared to undamaged controls.
Sufficient swarming distance and the synchronization of mass swarm events (Henderson and Delaplane 1994; Henderson 1996) ensure mixing of alates from multiple different colonies resulting in high genetic diversity within each light trap sample (Husseneder et al. 2006).
Since the time scale in the measured data was shifted for the sake of synchronization of the conversion events of Rab5 and Rab7 domain proteins, we rescaled it in order to conduct a direct comparison of the numeric simulation (reference model) with the measured data: We used the transformation t ← 4 t + 850.
