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 …

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...

Influence of variations in threshold of bad mutations on age structure of the population

Maksymowicz, Andrzej Z - In: Physica A: Statistical Mechanics and its Applications 273 (1999) 1, pp. 150-157

Computer study of population evolution in a modified Penna model is presented, where different thresholds T for bad mutation may be assigned to individuals. The model indicates a possible source of such fluctuations of T due to embryo period of life before birth. Changes in age characteristics...

Optimising threshold levels for information transmission in binary threshold networks: Independent multiplicative noise on each threshold

Zhou, Bingchang; McDonnell, Mark D. - In: Physica A: Statistical Mechanics and its Applications 419 (2015) C, pp. 659-667

uniform noise is considered. Similar to previous results for additive noise, we find a bifurcation phenomenon in the optimal … threshold values, as the noise intensity changes. This occurs when the number of threshold units is greater than one. We also … study the optimal thresholds for combined additive and multiplicative Gaussian noise, and find that all threshold levels …

Order or chaos in Boolean gene networks depends on the mean fraction of canalizing functions

Karlsson, Fredrik; Hörnquist, Michael - In: Physica A: Statistical Mechanics and its Applications 384 (2007) 2, pp. 747-757

We explore the connection between order/chaos in Boolean networks and the naturally occurring fraction of canalizing functions in such systems. This fraction turns out to give a very clear indication of whether the system possesses ordered or chaotic dynamics, as measured by Derrida plots, and...
