An extended Korteweg-de Vries (KdV) equation is derived that describes the evolution and propagation of long interfacial gravity waves in the presence of a strong, space-time varying background. Provision is made in the derivation for a spatially varying lower depth so that some topographic eeects can also be included. The extended KdV model is applied to some simple scenarios in basins of cons...

Artificial Immune Systems (AIS) have long been used in the field of computer security and especially in Intrusion Detection systems. Intrusion detection based on AISs falls into two main categories. The first generation of AIS is inspired from adaptive immune reactions but, the second one which is called danger theory focuses on both adaptive and innate reactions to build a more biologically-re...

We explore the dynamical phases of unitary Clifford circuits with variable-range interactions, coupled to a monitoring environment. investigate two classes models, distinguished by action gates, which either are organized in clusters finite-range two-body or pair-wise interactions randomly distributed throughout system power-law distribution. find range plays key role characterizing both and th...
