Although the model does not include any nontrivial elementary processes such as nonlinear rheology or stochasticity, the system exhibits creep...

If the interaction is global among Ising spin elements and if the unfixed part is reequilibrated each time after fixing an element, t...

Often these models are defined on a state space of product form and only one of the components of the process is of direct interest. In this paper we extend the marginal process framework, which provides a marginal description of the ...

Experiments on single cavities are in general agreement with the predictions of the RCM. I...

]]>The presence or absence of symmetry in the connectivity between neurons affects the dynamics of neural networks. The authors of this paper use a network with partially symmetric connections to study this effect in the fixed-point and chaotic regimes. They find that in both cases symmetry increases the time scale of the dynamics, which could explain certain electrophysiological observations.

]]>A nested polyhedra model has been developed for magnetohydrodynamic turbulence. Driving only the velocity field at large scales with random, divergence-free forcing results in a clear, stationary ${k}^{-5/3}$ spectrum for both kinetic and magnetic energies. Since the model naturally effaces disparate scale...
