             abstract = "In this study, we present multifractal analysis of the equatorial 
                         E-F transition region data obtained from an in-situ experiment 
                         performed at Alc{\^a}ntara (2.4°S; 44.4°W), Brazil. Earlier 
                         investigations (Odriozola et al., 2017) on this data indicated the 
                         presence of smallmedium scale irregularities in the valley region. 
                         At the time of launch, ground based equipment detected conditions 
                         favorable for the generation of plasma bubbles in F-region. Also, 
                         this experiment can be considered as the first to detect a 
                         scenario similar to the one observed in the RTI maps at Jicamara 
                         (Woodman and Chau, 2001). Multifractal Detrended Fluctuation 
                         Analysis (MFDFA) and P-model (Meneveau and Sreenivasan, 1987) fit 
                         is used to analyze the electron density time series. Analysis of 
                         the scaling pattern obtained from the singularity spectra and 
                         fitted p-values help to understand the nature of ionospheric 
                         turbulence in E-F transition region. The multifractal structure 
                         function is able to characterize nonlinear spatio-temporal 
                         behavior and complex processes such as non-homogenous energy 
                         cascades that could be present in the Ionospheric plasma bubble 
                         region. This procedure is relatively unprecedented since studies 
                         of equatorial E-region and the intermediate region between the E 
                         and F layers at nighttime are scarce. Power spectral density (PSD) 
                         obtained from this data has shown the presence of dual slope under 
                         small-medium scale irregularities. Preliminary results show the 
                         PSD slope varies as 0. 9<\β1< . for medium and 0. 4< 
                         \β2<3. for small scales and energy cascading probability as 
                         0.15 < p < 0.4 suggesting that the main underlying physical 
                         process is a nonhomogeneous multiplicative cascade.",
