Spiral formation and degeneration in heterogeneous excitable media (2009)
Journal Article

Spontaneous spiral formation occurs when an excitation wave is input to a heterogeneous network of low- and high-light-intensity cells projected onto a light-sensitive Belousov-Zhabotinsky reaction. The range of network conditions where spirals form... Read More about Spiral formation and degeneration in heterogeneous excitable media.

Developing proximity graphs by physarum polycephalum: Does the plasmodium follow the toussaint hierarchy? (2009)
Journal Article

Plasmodium of Physarum polycephalum spans sources of nutrients and constructs varieties of protoplasmic networks during its foraging behavior. When the plasmodium is placed on a substrate populated with sources of nutrients, it spans the sources with...

Implementation of glider guns in the light-sensitive Belousov-Zhabotinsky medium (2009)
Journal Article

In cellular automata models a glider gun is an oscillating pattern of nonquiescent states that periodically emits traveling localizations (gliders). The glider streams can be combined to construct functionally complete systems of logical gates and th...

Pattern Languages for CMC Design (2009)
Book Chapter

Three decades ago the concept of pattern languages were introduced in the field of architecture and have since become widely used in object-oriented programming and HCI. However their use in computing is divergent from Alexander’s original goals on... Read More about Pattern Languages for CMC Design.

Solving the density classification task using cellular automaton 184 with memory (2009)
Journal Article

Variance analysis as practice-based evidence (2009)
Book Chapter

Integrated care pathways, a fine-grained form of medical guideline including the explicit recording of any deviation, or ‘variance’, have been perceived by some as overly prescriptive, limiting clinical freedom and promoting ‘cookbook medicine’. Howe... Read More about Variance analysis as practice-based evidence.

Simple collision-based chemical logic gates with adaptive computing (2009)
Journal Article

Are complex systems hard to evolve? (2009)
Journal Article

Evolutionary complexity is measured here by the number of trials/evaluations needed for evolving a logical gate in a nonlinear medium. Behavioral complexity of the gates evolved is characterized in terms of cellular automata behavior. We speculate th... Read More about Are complex systems hard to evolve?.
