The use of MS for the investigation of irritable bowel syndrome and inflammatory bowel disease (2013)
Journal Article
Ratcliffe, N. M., de Lacy Costello, B., & Shepherd, S. (2013). The use of MS for the investigation of irritable bowel syndrome and inflammatory bowel disease. Clinical laboratory international, 37, 18-20

Currently, the diagnosis of bowel diseases such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) relies on invasive and expensive procedures. Identification of biomarker-based tests to aid diagnosis is an important area of resea...

Does the D.C. response of memristors allow robotic short-term memory and a possible route to artificial time perception? (2013)
Presentation / Conference
Gale, E., de Lacy Costello, B., & Adamatzky, A. (2013, May). Does the D.C. response of memristors allow robotic short-term memory and a possible route to artificial time perception?. Paper presented at Workshop Unconventional Approaches to Robotics, Automation and Control Inspired by Nature (UARACIN) in:

Time perception is essential for task switching, and in the mammalian brain appears alongside other processes. Memristors are electronic components used as synapses and as models for neurons. The d.c. response of memristors can be considered as a typ...

Design of a hybrid robot control system using memristor-model and ant-inspired based information transfer protocols (2013)
Presentation / Conference
Gale, E., de Lacy Costello, B., & Adamatzky, A. (2013, May). Design of a hybrid robot control system using memristor-model and ant-inspired based information transfer protocols. Paper presented at Workshop on Unconventional Approaches to Robotics, Automation and Control Inspired by Nature

It is not always possible for a robot to process all the information from its sensors in a timely manner and thus quick and yet valid approximations of the robot's situation are needed. Here we design hybrid control for a robot within this limit usin...

Presentation / Conference
Gale, E., Matthews, O., de Lacy Costello, B., & Adamatzky, A. (2013, April). Beyond Markov chains, towards adaptive memristor network-based music generation. Paper presented at First AISB symposium on Music and Unconventional Computing

We undertook a study of the use of a memristor network for music generation, making use of the memristor's memory to go beyond the Markov hypothesis. Seed transition matrices are created and populated using memristor equations, and which are shown to...

Diagnosing irritable bowel syndrome (IBS) can be a challenge; many clinicians resort to invasive investigations in order to rule out other diseases and reassure their patients. Volatile organic metabolites (VOMs) are emitted from feces; understanding... Read More about An Investigation of Fecal Volatile Organic Metabolites in Irritable Bowel Syndrome.

Volatiles from oral anaerobes confounding breath biomarker discovery (2013)
Journal Article

The levels of compounds in exhaled mouth air do not necessarily reflect levels in the systemic circulation as bacteria can bio-transform substrates to produce compounds within the mouth. This should be of concern to researchers measuring breath volat... Read More about Volatiles from oral anaerobes confounding breath biomarker discovery.

Working Paper
Gale, E., de Lacy Costello, B., & Adamatzky, A. The effect of electrode size on memristor properties: an experimental and theoretical study

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.
