A comprehensive power spectral density analysis of astronomical time series I: the Fermi-LAT gamma-ray light curves of selected blazars
The LCs and power spectral densities (PSDs) were investigated with various methods: Fourier transform, Lomb-Scargle periodogram (LSP), wavelet scalogram, autoregressive moving average (ARMA) process, continuous-time ARMA (CARMA), Hurst exponent ($H$), and the $\mathcal{A}-\mathcal{T}$ plane.

Distinguishing short and long $Fermi$ gamma-ray bursts
Two classes of gamma-ray bursts (GRBs), short and long, have been determined without any doubts, and are usually ascribed to different progenitors, yet these classes overlap for a variety of descriptive parameters.
Correlation between the Hurst exponent and the maximal Lyapunov exponent: examining some low-dimensional conservative maps
A tight correlation between the HEs and mLEs is found, with the Spearman rank $\rho=0. 83$ and $\rho=0. 75$ for the Chirikov and 2D Froeschl\'e maps, respectively.
