Evolution of plastic learning in spiking networks via memristive connections (2012)
Journal Article

This paper presents a spiking neuroevolutionary system which implements memristors as plastic connections, i.e., whose weights can vary during a trial. The evolutionary design process exploits parameter self-adaptation and variable topologies, allowi... Read More about Evolution of plastic learning in spiking networks via memristive connections.

A diagnostic apparatus for analysing a sample to diagnose disease (2012)
Patent

A diagnostic apparatus (10) for analysing a sample to diagnose disease, the apparatus (10) comprising: a separating element (16) for separating gas derived from the sample into component parts; a sensor arrangement (18) coupled to the separating elem...

On architectures of circuits implemented in simulated Belousov-Zhabotinsky droplets (2012)
Journal Article

When lipid vesicles filled with Belousov-Zhabotinsky (BZ) excitable chemical medium are packed in tight assembles, waves of excitation may travel between the vesicles. When several waves meet in a vesicle some fragments may deflect, others can annihi... Read More about On architectures of circuits implemented in simulated Belousov-Zhabotinsky droplets.

Time-dependent wave selection for information processing in excitable media (2012)
Journal Article

We demonstrate an improved technique for implementing logic circuits in light-sensitive chemical excitable media. The technique makes use of the constant-speed propagation of waves along defined channels in an excitable medium based on the Belousov-Z...

Concept – including filamentary conduction in the mem-mon theory of memristance improves the model for ‘triangular’ memristors

Filamentary extension of the mem-con theory of memristance and its application to titanium dioxide sol-gel memristors (2012)
Preprint / Working Paper

Titanium dioxide sol-gel memristors have two different modes of operation, believed to be dependent on whether there is bulk memristance, i.e. memristance throughout the whole volume or filamentary memristance, i.e. memristance caused by the connecti...

The effect of electrode size on memristor properties: an experimental and theoretical study (2012)
Preprint / Working Paper

The width of the electrodes is not included in the current phenomenological models of memristance, but is included in the memory-conservation (mem-con) theory of memristance. An experimental study of the effect of changing the top electrode width was... Read More about The effect of electrode size on memristor properties: an experimental and theoretical study.
