Simulation of robustness against lesions of cortical networks (2007)
Journal Article
Kaiser, M., Martin, R., Andras, P., & Young, M. P. (2007). Simulation of robustness against lesions of cortical networks. European Journal of Neuroscience, 25(10), 3185-3192. https://doi.org/10.1111/j.1460-9568.2007.05574.x

Structure entails function, and thus a structural description of the brain will help to understand its function and may provide insights into many properties of brain systems, from their robustness and recovery from damage to their dynamics and even...

An analysis of the dynamics of British academic science (2007)
Report
Andras, P., Herald, N. D., & Charlton, B. (2007). An analysis of the dynamics of British academic science. Newcastle-upon-Tyne: Newcastle University

We analysed the ranking and market share dynamics of main British universities based on their research output production (publications and citations). The data that we analysed is dominated very much by research output in natural and medical sciences... Read More about An analysis of the dynamics of British academic science.

Abstract communications systems theory may be a valuable tool for the description, prediction and control of organizations. An organization is conceptualized as an abstract system of inter-human communications; humans are the main organization 'commu...

The language of cortical dynamics (2006)
Presentation / Conference Contribution
Andras, P. (2006, September). The language of cortical dynamics. Presented at Second International Symposium, CompLife 2006, Cambridge

Cortical dynamics can be recorded in various ways. Theoretical works suggest that analyzing the dynamics of recorded activities might reveal the workings of the underlying neural system. Here we describe the extraction of an activity pattern language... Read More about The language of cortical dynamics.

Fault tolerance and network integrity measures: the case of computer-based systems (2006)
Presentation / Conference Contribution
Andras, P., Idowu, O., & Periorellis, P. (2006, April). Fault tolerance and network integrity measures: the case of computer-based systems. Presented at AISB'06: Network Analysis in Natural Sciences and Engineering, Bristol

Fault tolerance is a key aspect of the dependability of complex computer-based systems. Fault tolerance may be difficult to measure directly in complex real world systems, and we propose here to measure it in terms of integrity preservation of the sy...

High-resolution multiple-unit EEG in cat auditory cortex reveals large spatio-temporal stochastic interactions (2006)
Journal Article
Wennekers, T., Ay, N., & Andras, P. (2007). High-resolution multiple-unit EEG in cat auditory cortex reveals large spatio-temporal stochastic interactions. BioSystems, 89(1-3), 190-197. https://doi.org/10.1016/j.biosystems.2006.04.017

It has been argued that information processing in the cortex is optimised with regard to certain information theoretic principles. We have, for instance, recently shown that spike-timing dependent plasticity can improve an information-theoretic measu...

Cortical activity pattern computation (2006)
Journal Article
Andras, P., & Wennekers, T. (2007). Cortical activity pattern computation. BioSystems, 87(2-3), 179-185. https://doi.org/10.1016/j.biosystems.2006.09.012

Neural computations are modelled in various ways, but still there is no clear understanding of how the brain performs its computational tasks. This paper presents new results about analysis of neural processes in terms of activity pattern computation... Read More about Cortical activity pattern computation.

Extraction of an activity pattern language from EEG data (2006)
Journal Article
Andras, P. (2006). Extraction of an activity pattern language from EEG data. Neurocomputing, 69(10-12), 1313-1316. https://doi.org/10.1016/j.neucom.2005.12.099

Recent research shows that activity patterns play an important role in neural information processing. This seems to be the case both at micro- and macro-level processes within the nervous system. An important question is how to extract such activity... Read More about Extraction of an activity pattern language from EEG data.

Managing Missed Interactions in Distributed Virtual Environments (2006)
Presentation / Conference Contribution
Parkin, S., Andras, P., & Morgan, G. (2006, May). Managing Missed Interactions in Distributed Virtual Environments. Presented at 12th Eurographics conference on Virtual Environments, Lisbon, Portugal

A scalable distributed virtual environment (DVE) may be achieved by ensuring virtual world objects communicate their actions to only those objects that fall within their influence, reducing the need to send and process unnecessary messages. A missed... Read More about Managing Missed Interactions in Distributed Virtual Environments.

Uncertainty and cooperation: Analytical results and a simulated agent society (2006)
Journal Article
Andras, P., Lazarus, J., Roberts, G., & Lynden, S. J. (2006). Uncertainty and cooperation: Analytical results and a simulated agent society. Journal of Artificial Societies and Social Simulation, 9(1),

Uncertainty is an important factor that influences social evolution in natural and artificial environments. Here we distinguish between three aspects of uncertainty. Environmental uncertainty is the variance of resources in the environment, perceived... Read More about Uncertainty and cooperation: Analytical results and a simulated agent society.

Kohonen networks with graph-based augmented metrics (2005)
Presentation / Conference Contribution
Andras, P., & Idowu, O. (2005, December). Kohonen networks with graph-based augmented metrics. Presented at WSOM 2005, Paris

Correct and efficient text classification is a major challenge in today’s world of rapidly increasing amount of accessible electronic text data. Kohonen networks have been applied to document classification with comparable success to other document c... Read More about Kohonen networks with graph-based augmented metrics.

Stochastic Interaction in Neural Systems (2005)
Presentation / Conference Contribution
Wennekers, T., Ay, N., & Andras, P. (2005, August). Stochastic Interaction in Neural Systems. Presented at 6th Neural Coding Workshop, Marburg, Germany

Brains are information processing systems evolutionary adapted since millions of years. It seems plausible therefore that they follow information theoretic optimization principles. In the early visual system mutual information maximization (Infomax)... Read More about Stochastic Interaction in Neural Systems.

Environmental risk (2005)

The origins of life - the ‘protein interaction world’ hypothesis: protein interactions were the first form of self-reproducing life and nucleic acids evolved later as memory molecules (2005)
Journal Article
Andras, P., & Andras, C. (2005). The origins of life - the ‘protein interaction world’ hypothesis: protein interactions were the first form of self-reproducing life and nucleic acids evolved later as memory molecules. https://doi.org/10.1016/j.mehy.2004.11.029

The ‘protein interaction world’ (PIW) hypothesis of the origins of life assumes that life emerged as a self-reproducing and expanding system of protein interactions. In mainstream molecular biology, ‘replication’ refers to the material copying of mol...
