A variety of linear models are available to represent common active electronic devices such as transistors and vacuum tubes. Devices operating under large-signal conditions often require nonlinear ...

Figure 1: Feedback in directional persistence transforms transport dynamics. Figure 3: Combined experiments and numerical modelling show that positive feedback in directional persistence during ...

Modifications to existing theories have enabled researchers to better understand and model the dynamics of systems which don't obey conventional laws of diffusion. In normal circumstances, particles ...

In its original form, Gibbs-Boltzmann statistical mechanics cannot describe “active matter,” such as living, driven, or self-propelled systems. Contemporary models of swarming and flocking behaviors, ...
