Evolutionary Targeted Discovery of Influenza A Virus Replication Inhibitors
(2018-01-29)Influenza A is one of the most prevalent and significant viral infections worldwide, resulting in annual epidemics and occasional pandemics. Upon infection, antiviral drugs targeting the neuraminidase protein and M2 protein ... -
Evolutionary tuning method for automatic impedance matching in communication systems
(Institute of Electrical and Electronics Engineers (IEEE), 1998)An evolutionary tuning method for automatic impedance matching in radio communication systems is developed based on genetic algorithms (GA). A detailed tuning procedure is presented and a software package has been developed. ... -
Evolvability of the gentotype-phenotype relation in populations of self-replicating digital organisms in a Tierra-like system
(2003)In other Tierra-like systems the genotype is a sequence of instructions and the phenotype is the corresponding executed algorithm. This way the genotype-phenotype mapping is constrained by the structure of a creature’s ... -
The evolved B[e] star HD 87643: observations and a radiation-driven disc wind model for B[e] stars
(1998)New high resolution spectroscopic and medium resolution spectropolarimetric data, complemented with optical broad and narrow band imaging, of the B[e] star HD 87643 are presented. The spectrum of HD 87643 exhibits the ... -
Evolved solar systems in Praesepe
(American Institute of Physics (AIP), 2011)We have obtained near-IR photometry for the 11 Praesepe white dwarfs, to search for an excess indicative of a dusty debris disk. All the white dwarfs are in the DAZ temperature regime, however we find no indications of a ... -
Evolving a Lingua Franca and Associated Software Infrastructure for Computational Systems Biology - the Systems Biology Markup Language (SBML) Project
(2004)Biologists are increasingly recognising that computational modelling is crucial for making sense of the vast quantities of complex experimental data that are now being collected. The systems biology field needs agreed-upon ... -
Evolving biological clocks using genetic regulatory networks

Evolving computational neural systems using synthetic developmental mechanisms
(Elsevier, 2003)Biological development is highly complex, beginning with an egg and resulting in a complete living organism (Purves and Lichtman, 1985). Development is essentially sequential, establishing a gross structure which becomes ... -
Evolving dendritic morphology and parameters in biologically realistic model neurons for pattern recognition
(Springer Nature, 2012)This paper addresses the problem of how dendritic topology and other properties of a neuron can determine its pattern recognition performance. In this study, dendritic trees were evolved using an evolutionary algorithm, ... -
An Evolving Ecosystems Approach to Generating Complex Agent Behaviour
(Institute of Electrical and Electronics Engineers (IEEE), 2007)We propose an evolving ecosystem approach to evolving complex agent behaviour based on the principle of natural selection. The agents start with very limited functional design and morphology and neural controllers are ... -
Evolving Embodied Genetic Regulatory Network-driven Control Systems
(2003)We demonstrate the evolution of simple embodied Genetic Regulatory Networks (GRNs) as real-time control systems for robotic and software-based embodied Artificial Organisms, and present results from two experimental ... -
The evolving far-IR galaxy luminosity function and dust-obscured star-formation rate density out to z~5
(2017-11-11)We present a new measurement of the evolving galaxy far-IR luminosity function (LF) extending out to redshifts z~5, with resulting implications for the level of dust-obscured star-formation density in the young Universe. ... -
An evolving model of best practice in a community physical activity programme: A case study of ‘Active Herts
(2021-10-06)Background: Community-based physical activity programs typically evolve to respond to local conditions and feedback from stakeholders. Process evaluations are essential for capturing how programs are implemented, yet often ... -
Evolving morphological and behavioral diversity without predefined behavior primitives
(MIT Press, 2008)Virtual ecosystems, where natural selection is used to evolve complex agent behavior, are often preferred to traditional genetic algorithms because the absence of an explicitly defined fitness allows for a less constrained ... -
Evolving Non-Dominated Parameter Sets for Computational Models from Multiple Experiments
(2014-04-25)Creating robust, reproducible and optimal computational models is a key challenge for theorists in many sciences. Psychology and cognitive science face particular challenges as large amounts of data are collected and many ... -
Evolving robot controllers in PDL using genetic programming
(Institute of Electrical and Electronics Engineers (IEEE), 2011)We demonstrate how autonomous agents can be evolved whose controllers are programs in the dynamical systems-oriented, behaviour-based PDL language introduced by Luc Steels. Controllers evolved using a physics simulator ... -
Evolving Sims's creatures for bipedal gait
(Institute of Electrical and Electronics Engineers (IEEE), 2011-01-01)In this paper we describe the design of an approach to evolve Sims's creatures with morphology and behaviour similar to biped animals. Our hypothesis is that biases in morphology that encourage limb specialisation, combined ...
