Wavelength scaling and square/stripe and grain mobility transitions in vertically oscillated granular layers

Umbanhowar, Paul B.; Swinney, Harry L. - In: Physica A: Statistical Mechanics and its Applications 288 (2000) 1, pp. 344-362

pattern apparently arises from a bending of the granular layer. For f at vgm less than fss and v<vgm, patterns are tenuous and …

Dynamic renormalization group and noise induced transitions in a reaction diffusion model

Zorzano, M.P; Hochberg, David; Morán, Federico - In: Physica A: Statistical Mechanics and its Applications 334 (2004) 1, pp. 67-77

We investigate how additive weak noise (correlated as well as uncorrelated) modifies the parameters of the Gray–scott reaction diffusion system by performing numerical simulations and applying a renormalization group (RG) analysis in the neighborhood of the spatial scale where biochemical...

The cascading vulnerability of the directed and weighted network

Jin, Wei-Xin; Song, Ping; Liu, Guo-Zhu; Stanley, H. Eugene - In: Physica A: Statistical Mechanics and its Applications 427 (2015) C, pp. 302-325

The cascading failure can bring a huge loss for most real-world networks; but, we cannot uncover fully the mechanism and law of the cascading events occurrence. Most networks in which the cascading failure occurred are based on the various ‘flows’, such as power, oils, and information;...

Correlation analysis of different vulnerability metrics on power grids

Ouyang, Min; Pan, Zhezhe; Hong, Liu; Zhao, Lijing - In: Physica A: Statistical Mechanics and its Applications 396 (2014) C, pp. 204-211

Many scholars have used different metrics to quantify power grid vulnerability in the literature, but how correlated … these metrics are is an interesting topic. This paper defines vulnerability as the performance drop of a power grid under a … respectively quantify power grid vulnerability V under different node or edge failure probabilities fp and then analyzes the …

Deep information from limited observation of robust yet fragile systems

LaViolette, Randall A.; Glass, Kristin; Colbaugh, Richard - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 17, pp. 3283-3287

We show how one can completely reconstruct even moderately optimized configurations of the Forest Fire model with relatively few observations. We discuss the relationship between the deep information from limited observations (DILO) to the robust-yet-fragile (RYF) property of the Forest Fire...
