Reaction-diffusion controllers for robots (2009)
Book Chapter

Excitable systems, particularly spatially extended media, exhibit a wide variety of travelling patterns and different modes of interaction. The Belousov-Zhabo-tinsky [1] (BZ) reaction is the most well known and extensively studied example of non-line... Read More about Reaction-diffusion controllers for robots.

Analysis of faecal volatile organic compounds in preterm infants who develop necrotising enterocolitis: A pilot study (2009)
Journal Article

OBJECTIVE:: To determine differences in the profiles of volatile organic compounds (VOCs) in faecal samples from preterm infants who develop necrotising enterocolitis (NEC) compared with non-NEC controls. MATERIALS AND METHODS:: Daily faecal samples... Read More about Analysis of faecal volatile organic compounds in preterm infants who develop necrotising enterocolitis: A pilot study.

Experimental validation of binary collisions between wave fragments in the photosensitive Belousov–Zhabotinsky reaction (2009)
Journal Article

Using the examples of an excitable chemical system (the Belousov–Zhabotinsky medium) and plasmodium of Physarum polycephalum we show that universal computation in a geometrically unconstrained medium is only possible when resources (excitability or c...

Experimental validation of binary collisions between wave fragments in the photosensitive Belousov-Zhabotinsky reaction (2009)
Journal Article

We present experimental verification of wave fragment collisions in the sub-excitable Belousov-Zhabotinsky medium observed previously in simulation [Adamatzky A, De Lacy Costello B. Binary collisions between wave fragments in a sub-excitable Belousov...

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.

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...

Reaction diffusion computers (2009)
Book

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

Chemical tessellations (2009)
Journal Article

We report a simple set of chemical reactions based on the reaction of a range of metal salts with potassium ferricyanide loaded gels that spontaneously produce complex and colorful tessellations of the plane. These reactions provide a great resource... Read More about Chemical tessellations.

Fine control and selection of travelling waves in Inorganic Pattern Forming Reactions (2009)
Journal Article

Under normal reaction conditions [AlCl3 0.28-0.34M and NaOH 2.5M A.Volford et al.] spontaneous spiral and circular travelling precipitate waves were observed. We constructed a phase diagram for the reaction and identified a large controllable region... Read More about Fine control and selection of travelling waves in Inorganic Pattern Forming Reactions.
