The pulse coupled neural network (PCNN) models are described. The linking field modulation term is shown to be a universal feature of any biologically grounded dendritic model. Applications and implementations of PCNN's are reviewed. Application based variations and simplifications are summarized. The PCNN image decomposition (factoring) model is described(More)
The conditional saddle-point heights (conditional barriers) that preside over the emission of complex fragments (Z = 2 — 11) from compound nuclei have been obtained from the excitation functions of individual fragments in the reaction He+""Ag. The magnitudes of the barriers and their dependence on mass asymmetry may be used to verify important features of(More)
F has been studied in the reaction 90-MeV He+ " 'Ag. Although the yields of the heavier elements are orders of magnitude less than for He, the energy spectra, charge, and angular distributions indicate that an equilibrium statistical process is responsible for the production of these heavy nuclei in the backward hemisphere. The typical compound-nucleus(More)
The hydrodynamic interactions of micro-silica spheres trapped in a variety of networks using holographic optical tweezers are measured and characterized in terms of their predicted eigenmodes. The characteristic eigenmodes of the networks are distinguishable within 20-40 seconds of acquisition time. Three different multi-particle networks are considered; an(More)
