Attempt to distinguish electric signals of a dichotomous nature.
Varotsos PA, Sarlis NV, Skordas ES. Varotsos PA, et al. Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Sep;68(3 Pt 1):031106. doi: 10.1103/PhysRevE.68.031106. Epub 2003 Sep 23. Phys Rev E Stat Nonlin Soft Matter Phys. 2003. PMID: 14524749
For q values approximately between 1 and 2 the signals are classified and ICFMC lies between the other two types. For q=1, the "entropy" S identical with <chilnchi>-<chi>ln<chi> of ICFMC almost equals that of a "uniform" distribution, while the AN and SES …

Minima of the fluctuations of the order parameter of global seismicity.
Sarlis NV, Christopoulos SR, Skordas ES. Sarlis NV, et al. Chaos. 2015 Jun;25(6):063110. doi: 10.1063/1.4922300. Chaos. 2015. PMID: 26117104 Free article.
It has been recently shown [N. V. Sarlis, Phys. Rev. E 84, 022101 (2011) and N. V. Sarlis and S.-R. G. Christopoulos, Chaos 22, 023123 (2012)] that earthquakes of magnitude M greater or equal to 7 are globally correlated. ...This phenomenon corroborates the recent f …

Some properties of the entropy in the natural time.
Varotsos PA, Sarlis NV, Tanaka HK, Skordas ES. Varotsos PA, et al. Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Mar;71(3 Pt 1):032102. doi: 10.1103/PhysRevE.71.032102. Epub 2005 Mar 22. Phys Rev E Stat Nonlin Soft Matter Phys. 2005. PMID: 15903469
We show that the entropy S , defined as S identical with chi ln chi - chi ln chi [Phys. Rev. E 68, 031106 (2003)] where chi stands for the natural time [Phys. ...

Entropy in the natural time domain.
Varotsos PA, Sarlis NV, Skordas ES, Lazaridou MS. Varotsos PA, et al. Phys Rev E Stat Nonlin Soft Matter Phys. 2004 Jul;70(1 Pt 1):011106. doi: 10.1103/PhysRevE.70.011106. Epub 2004 Jul 30. Phys Rev E Stat Nonlin Soft Matter Phys. 2004. PMID: 15324041
A surrogate data analysis is presented, which is based on the fluctuations of the "entropy" S defined in the natural time domain [Phys. Rev. E 68, 031106 (2003)]]. This entropy is not a static one such as, for example, the Shannon entropy. The analysis is applied to …
