                         dynamical properties of ionospheric plasma irregularities using 
                         advanced computational non-linear algorithms is providing new 
                         insights into their turbulent-like nature, for instance, the 
                         evidence of energy distribution via multiplicative cascade. In 
                         this study, we present multifractal analysis of the equatorial F 
                         region in situ data obtained from two different experiments 
                         performed at Alc{\^a}ntara (2.4°S; 44.4°W), Brazil to explore 
                         their scaling structures. First experiment observed several 
                         large-medium scale plasma bubbles whereas second experiment 
                         observed vertical uplift of the base of F region. Multifractal 
                         detrended fluctuation analysis and p-model fit is used to analyze 
                         the plasma density fluctuation time series. Result shows presence 
                         of multifractality with degree of multifractality 0.53-0.93 with 
                         0.3 <= p <= 0.4 cascading probability for first experiment. 
                         Another experimental data also exhibits multifractality with 
                         degree of multifractality 0.19-0.27 with 0.42 <= p <= 0.44 
                         cascading probability in the ionospheric plasma irregularities. 
                         Our results confirm the nonhomogeneous nature of plasma 
                         irregularities and characterize the underlying nonhomogeneous 
                         multiplicative cascade hypothesis in the ionospheric medium. 
                         Differences in terms of scaling and complexity in data belonging 
                         to different types of phenomena are also addressed.",
