Journal Article
Younger, D., Matranga, M. A., Costello, B. D. L., Kitson, S., Adamatzky, A., & de Lacy Costello, B. (2011). Computing with liquid crystal fingers: Models of geometric and logical computation. Physical Review E, 84(6), https://doi.org/10.1103/PhysRevE.84.061702

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...

Comparison of ant-inspired gatherer allocation approaches using memristor-based environmental models (2011)
Presentation / Conference
Gale, E., de Lacy Costello, B., & Adamatzky, A. (2011, December). Comparison of ant-inspired gatherer allocation approaches using memristor-based environmental models. Paper presented at Bioadcom 2011 Workshop on Bio-inspired Approaches to Advanced Computing and Communications (BioAdcom2011)

Memristors are used to compare three gathering techniques in an already-mapped environment where resource locations are known. The All Site model, which apportions gatherers based on the modeled memristance of that path, proves to be good at increasi...

Neuromorphic computing with memristors: Preliminary experimental results (2011)
Presentation / Conference
Gale, E., de Lacy Costello, B., & Adamatzky, A. (2011, November). Neuromorphic computing with memristors: Preliminary experimental results. Poster presented at Building Bridges to Build Brains

Individual memristors have been observed demonstrating neuron-like spiking patterns. It has been shown elsewhere that memristors provide superior modelling for neurons then the Hodgkin-Huxley model. Due to these results we expect memristors to be e... Read More about Neuromorphic computing with memristors: Preliminary experimental results.

Biology and computing (2011)
Presentation / Conference
Gale, E. (2011, November). Biology and computing. Presented at Faculty Research Colloquium

Memristors, the recently discovered 4th fundamental circuit element, have been used as models for biological components, such as neurons. It may be that neurons are memristors, rather than just conveniently modeled by them. This presentation covers r... Read More about Biology and computing.
