1/f fluctuations under acoustic cavitation of liquids

Skokov, V.N.; Koverda, V.P.; Reshetnikov, A.V.; … - In: Physica A: Statistical Mechanics and its Applications 364 (2006) C, pp. 63-69

A regime of a generation of fluctuations with 1/f power spectra under cavitation of liquids in an ultrasonic field has been found experimentally. The acoustic cavitation is accompanied by the formation of various spatial structures and scale-invariant distribution functions of fluctuations. It...

Modeling intrinsic noise in random Boolean networks

Hung, Yao-Chen; Lin, Chai-Yu - In: Physica A: Statistical Mechanics and its Applications 395 (2014) C, pp. 121-127

Noise has crucial effects on biological processes, chemical reactions, and various chaotic systems. This study explores … the dynamical properties of noise in random Boolean networks, in which the stochasticity may cause significant deviations … from deterministic descriptions. Such noise is intrinsic and results from the discrete dynamics of finite populations. By …

Nonlinearity in high-frequency stock returns: Evidence from the Athens Stock Exchange

Anagnostidis, Panagiotis; Emmanouilides, Christos J. - In: Physica A: Statistical Mechanics and its Applications 421 (2015) C, pp. 473-487

higher-order stochastic nonlinearity. Rather, it is reminiscent of a random process. We conclude that the ACSPI data are … nonlinear; however, nonlinearity is attributed to persistent ARCH effects. …

Dynamic analysis of heartbeat rate signals of epileptics using multidimensional phase space reconstruction approach

Su, Zhi-Yuan; Wu, Tzuyin; Yang, Po-Hua; Wang, Yeng-Tseng - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 10, pp. 2293-2305

The heartbeat rate signal provides an invaluable means of assessing the sympathetic–parasympathetic balance of the human autonomic nervous system and thus represents an ideal diagnostic mechanism for detecting a variety of disorders such as epilepsy, cardiac disease and so forth. The current...

Continuous transforming the BTW to the Manna model

Asasi, H.; Moghimi-Araghi, S.; Najafi, M.N. - In: Physica A: Statistical Mechanics and its Applications 419 (2015) C, pp. 196-202

In this paper we define some stochastic perturbations of the BTW model which make it into Manna model. These models have a continuous parameter p, where p=0 and 1 correspond to the BTW and Manna models respectively. We have investigated the properties of the statistical observables of the waves...
