Fracture in disordered media is a complex problem for which a definitive physical and
theoretical treatment is still lacking. We view earthquakes (EQ’s) as large-scale fracture …

We argue that the fluctuations of the order parameter in a complex system at the critical point
can be described in terms of intermittent dynamics of type I. Based on this observation we …

We consider a critical system at equilibrium in terms of a characteristic extensive quantity M=M(φ)
where φ is the corresponding order parameter. The random averaging over the …

A theoretical scheme which relates multiparticle states generated in ultrarelativistic nuclear
collisions to a QCD phase transition is considered in the framework of the universality class …

Precursory fracture induced electromagnetic (EM) emissions, rooted in opening cracks and
ranging from MHz to kHz, with the MHz appearing earlier, are produced and detected both at …

A detailed study of correlated scalars, produced in collisions of nuclei and associated with
the σ-field fluctuations, (δσ) 2 =〈σ 2 〉, at the QCD critical point (critical fluctuations), is …

Earthquakes (EQs) are large-scale fracture phenomena in the Earth’s heterogeneous crust.
Fracture-induced physical fields allow a real-time monitoring of damage evolution in …

In this work we present the statistical and criticality analysis of the very low frequency (VLF)
sub-ionospheric propagation data recorded by a VLF/LF radio receiver which has recently …

The new field of complex systems supports the view that a number of systems arising from
disciplines as diverse as physics, biology, engineering, and economics may have certain …

We investigate the spontaneous contraction generated by the atria of a frog’s heart isolated
in a physiological solution. In the relaxation phase, the recorded time series for two different …
