Computing with liquid crystal fingers: Models of geometric and logical computation (2011)
Journal Article

When a voltage is applied across a thin layer of cholesteric liquid crystal, fingers of cholesteric alignment can form and propagate in the layer. In computer simulation, based on experimental laboratory results, we demonstrate that these cholesteric...

On computing in fine-grained compartmentalised Belousov-Zhabotinsky medium (2011)
Journal Article

We introduce results of computer experiments on information processing in a hexagonal array of vesicles filled with Belousov-Zhabotinsky (BZ) solution in a sub-excitable mode. We represent values of Boolean variables by excitation wave-fragments and... Read More about On computing in fine-grained compartmentalised Belousov-Zhabotinsky medium.

Vesicle computers: Approximating a Voronoi diagram using Voronoi automata (2011)
Journal Article

Irregular arrangements of vesicles filled with excitable and precipitating chemical systems are imitated by Voronoi automata - finite-state machines defined on a planar Voronoi diagram. Every Voronoi cell takes four states: resting, excited, refracto... Read More about Vesicle computers: Approximating a Voronoi diagram using Voronoi automata.

Aluminium electrodes effect the operation of titanium oxide sol-gel memristors (2011)
Preprint / Working Paper

By a comparison between memristors made with aluminium and gold electrodes, this letter demonstrates that aluminium electrodes are an essential component of the TiO$_2$ sol-gel flexible memristor . Both slow varying `analogue' and sudden switching `d... Read More about Aluminium electrodes effect the operation of titanium oxide sol-gel memristors.

Sounds synthesis with slime mould of Physarum Polycephalum (2011)
Journal Article

This paper introduces a novel application of bionic engineering: a bionic musical instrument using Physarum polycephalum. Physarum polycephalum is a huge single cell with thousands of nuclei, which behaves like a giant amoeba. During its foraging beh...

On electrical correlates of physarum polycephalum spatial activity: Can we see physarum machine in the dark? (2011)
Journal Article

Plasmodium of Physarum polycephalum is a single cell visible by unaided eye, which spans sources of nutrients with its protoplasmic network. In a very simple experimental setup we recorded electric potential of the propagating plasmodium. We discover...

On attraction of slime mould Physarum polycephalum to plants with sedative properties (2011)
Journal Article

A plasmodium of acellular slime mould Physarum polycephalum is a large single cell with many nuclei. Presented to a configuration of attracting and repelling stimuli a plasmodium optimizes its growth pattern and spans the attractants, while avoiding...

Towards evolving spiking networks with memristive synapses (2011)
Presentation / Conference Contribution

This paper presents a spiking neuro-evolutionary system which implements memristors as neuromodulatory connections, ie whose weights can vary during a trial. The evolutionary design process exploits parameter self-adaptation and a constructionist app... Read More about Towards evolving spiking networks with memristive synapses.

Cellular automaton supercolliders (2011)
Journal Article

Gliders in one-dimensional cellular automata are compact groups of non-quiescent and non-ether patterns (ether represents a periodic background) translating along automaton lattice. They are cellular automaton analogous of localizations or quasi-loca... Read More about Cellular automaton supercolliders.

Computational modalities of Belousov-Zhabotinsky encapsulated vesicles (2011)
Journal Article

We present both simulated and partial empirical evidences for the computational utility of many connected vesicle analogues of an encapsulated nonlinear chemical processing medium. By connecting small vesicles containing a solution of sub-excitable B... Read More about Computational modalities of Belousov-Zhabotinsky encapsulated vesicles.

Towards arithmetic circuits in sub-excitable chemical media (2011)
Journal Article

A sub-excitable Belousov-Zhabotinsky medium exhibits localized travelling excitations (in contrast to an excitable medium exhibiting target or spiral waves). Initially assymetric perturbations give birth to excitation wave-fragments. The shape and ve... Read More about Towards arithmetic circuits in sub-excitable chemical media.

Memristive excitable cellular automata (2011)
Journal Article

The memristor is a device whose resistance changes depending on the polarity and magnitude of a voltage applied to the device's terminals. We design a minimalistic model of a regular network of memristors using structurally-dynamic cellular automata.... Read More about Memristive excitable cellular automata.

On the internalisation, intraplasmodial carriage and excretion of metallic nanoparticles in the slime mould, Physarum polycephalum (2011)
Journal Article

The plasmodium of Physarum polycephalum is a large single cell visible with the naked eye. When inoculated on a substrate with attractants and repellents the plasmodium develops optimal networks of protoplasmic tubes which span sites of attractants (...

On polymorphic logical gates in subexcitable chemical medium (2011)
Journal Article

In a subexcitable light-sensitive Belousov-Zhabotinsky (BZ) chemical medium an asymmetric disturbance causes the formation of localized traveling wave-fragments. Under the right conditions these wave-fragments can conserve their shape and velocity ve... Read More about On polymorphic logical gates in subexcitable chemical medium.
