             abstract = "Phase synchronization may emerge from mutually interacting 
                         non-linear oscillators, even under weak coupling, when phase 
                         differences are bounded, while amplitudes remain uncorrelated. 
                         However, the detection of this phenomenon can be a challenging 
                         problem to tackle. In this work, we apply the Discrete Complex 
                         Wavelet Approach (DCWA) for phase assignment, considering signals 
                         from coupled chaotic systems and experimental data. The DCWA is 
                         based on the Dual-Tree Complex Wavelet Transform (DT-CWT), which 
                         is a discrete transformation. Due to its multi-scale properties in 
                         the context of phase characterization, it is possible to obtain 
                         very good results from scalar time series, even with 
                         non-phase-coherent chaotic systems without state space 
                         reconstruction or pre-processing. The method correctly predicts 
                         the phase synchronization for a chemical experiment with three 
                         locally coupled, non-phase-coherent chaotic processes. The impact 
                         of different time-scales is demonstrated on the synchronization 
                         process that outlines the advantages of DCWA for analysis of 
                         experimental data.",
