“…The slope (β) of ln (P) vs ln (f) gives the value of power spectral fractal dimension (D p ) through the Eq. (3) [23,24]. Similar to the complexity mapping studies of intricate structures by finding the fractal dimensions, the study of temporal changes in these structures is also essential.…”

The present work proposes a surrogate method for understanding and analyzing the replication of SARS CoV-2 through fractal and inertia moment (IM) analysis of cell culture images at different stages. The fractal analysis of images of cell culture, calculated by the box-counting and power spectral density methods, reflect the stages of virus infection, leading to the replication of the virus RNA and damaging the host cell. The linear increase of IM value reveals not only the proliferation of SARS CoV-2 by replication but also damage to the host cell with time. Thus, the work shows the possibility of fractal analysis and IM measurement for understanding the dynamics of the virus infection.

“…Thin films characterization is another field of technology that finds applications in bionanoscience where the method of fractal analysis can be effectively employed. In this article we would like to demonstrate the application of FD to analyze the surface morphology of nanostructured thin films [12,14]. We could see that the box-counting method is better results when compared to power spectral method.…”

“…The potential of fractals in the study of morphology of highly complex and irregular objects enables its application in the nano-world also. Literature reports [12][13][14][15][16][17] the use of fractal geometry in the morphological, optical, thermoelectric characterization of nanostructured materials where size and morphology play an important role.…”

We live in a world of high complexity in all means. The present article is an attempt to elucidate the potential of fractal analysis in understanding and quantifying the complexity. Of several methods of fractal analysis, we have used only the box counting and power spectral methods for explaining the potential of the technique. The application of fractal analysis in bio-nanosystems, thin films, are forensic science are exemplified though our own work.

“…In all these examples, fractal dimension is adopted as a tool to unwrap the hidden complex dynamics of spatio-temporal systems through various a e-mail: drssraman@gmail.com (corresponding author) methods. The diverse methods for fractalysis are the main reason for its application in various fields of science and technology [1,2,6,8,12]. The walking divider method is common for finding the fractal nature of linear features, the box-counting method for objects in any dimension, and the variogram method for area-based applications [13].…”

The paper deciphers the potential of fractal analysis in unveiling the complex plasma dynamics. The light from copper plasma is focused on the slit of a spectrometer, and the spectral variations across the slit are analysed. The plasma temperature (T ) computed from the spectrum at various spatial points of the slit also exhibits a variation similar to that of power spectral fractal dimension (Dp). The study reveals a strong correlation between T and Dp, reflecting the complex dynamics and the compositional anisotropy in plasma. At the plasma core, where the temperature is the highest, and the matter is in the ionised state, the Dp is high, and the lower temperature regions show a lower Dp value. The fractalysis helps analyse plasma temperature without knowing transition probability and the energy of the upperlevel corresponding to each value of wavelength. Thus, the power spectral fractalysis can be considered a surrogate method for understanding the plasma temperature and the particle dynamics involved.
