We propose a "social physics" model for two-group conflict. We consider two disputing groups. Each individual in in each of the two groups has a preference si regarding the way in which the conflict should be resolved. The individual preferences span a range between M (prone to protracted...

This article draws on several research domains and disciplines –social psychology, models of complex systems, and planning scenario analysis – to propose a “toy” model of the dynamics of inter-group conflicts. The ingroup-outgroup conflict literature supports the notion that inside...

We extend a sociophysics model of two-group conflict dynamics to three groups. The model with attractors and chaos is proposed as a tool for exploring and managing intractable conflicts. It can be used to generate scenarios of trajectories and outcomes. We use mean-field theory for long-range...

The scaling theory of type I superconductors close to the critical point is discussed. In this theory the exponent α = 0, which signals a heat capacity with a symmetric logarithmic divergence (non-classical behavior) superimposed on a discontinuity (classical behavior). An explicit scaling...

We present an analytical model of Stokes creeping flows in rectangular cavities. In the model, the fluid normal velocity at the wall is zero, while the fluid tangential velocity at the wall differs from the wall velocity. Numerical work is used to validate some of the ideas generated from this...

A nonlinear analysis based on Renyi entropy is applied to electromyography (EMG) time series from back muscles. The time dependence of the entropy of the EMG signal exhibits a crossover from a subdiffusive regime at short times to a plateau at longer times. We argue that this behavior...
