We study the distributions of dissipative and nondissipative avalanches separately in the stochastic Zhang (SP-Z) sandpile in two dimension. We find that dissipative and nondissipative avalanches obey simple power laws and do not have the logarithmic correction, while the avalanche distributions...

We focus here on the scaling properties of small interspecies differences between red cone opsin transmembrane proteins, using a hydropathic elastic roughening tool previously applied to the rhodopsin rod transmembrane proteins. This tool is based on a non-Euclidean hydropathic metric...

A thorough outlook on the origin of life needs to delineate a chemically rigorous, self-consistent path from highly heterogeneous, random ensembles of relatively simple organic molecules, to an entity that has rudimentary life-like characteristics. Such entity should be endowed with a capacity...

The avalanche dynamics in the Bak–Sneppen mechanism of self-organized criticality (SOC) is discussed. Rigorous arguments reveal the emergent history dependence that dominates the intermittent activity. In numerical studies the emergent SOC state shows glassy features, such as aging and an...

We review properties of the self-organized critical (SOC) forest-fire model (FFM). Self-organized critical systems drive themselves into a critical state without fine-tuning of parameters. After an introduction, the rules of the model, and the conditions for spiral shaped and SOC large-scale...

A system of granular material resting in a bin is driven by creating voids in the bulk of the medium. Modeling the grains by a collection of mono-disperse discs, we simulate the two dimensional version of the system. Using a ‘pseudo dynamics’ to study the dynamics of the system, we observe...

This paper outlines a synthesis of ecological economics with econophysics and other complexity approaches to economics. Arguably, the resulting “ecological econophysics” will be scientifically sounder than mainstream economics and much better suited to addressing a major challenge of our...

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...

This study provides empirical evidence of the relationship between spot and futures markets in Korea. In particular, the study focuses on the volatility spillover relationship between spot and futures markets by using three high-frequency (10 min, 30 min, and 1 h time-scales) intraday data sets...

Sea ice breaks up and regenerates rapidly during winter conditions in the Arctic. Analyzing satellite data from the Kara Sea, we find that the average ice floe size depends on weather conditions. Nevertheless, the frequency of floes of size A is a power law, N∼A−τ, where τ=1.6±0.2, for A...
