The Wilson-Cowan model describes the evolution of excitatory and inhibitory activity in a synaptically coupled neuronal network. As opposed to being a detailed biophysical model, the system is a coarse-grained description of the overall activity of a large-scale neuronal network, employing just two differential equations. Key parameters in the model are the strength of connectivity between each...

A significant issue in the design of catadioptric imaging systems is what shape the component mirrors should take. In this paper, we propose a novel algorithm for designing a free-form mirror. A free-form mirror expressed as the assembly of its gradients, is the most flexible surface representation that can form various shapes. We improve the shape reconstruction framework used in a photometric...

Small expectation values are difficult to measure in Monte Carlo calculations as they tend to get swamped by noise. Recently an algorithm has been proposed by Lüscher and Weisz [1] which allows one to measure expectation values which previously could not be measured reliably in Monte Carlo simulations. We will test our implementation of this algorithm by looking at Polyakov loop correlators and...

UKQCD’s dynamical fermion project uses the Generalised Hybrid Monte Carlo (GHMC) algorithm to generate QCD gauge configurations for a non-perturbatively O(a) improved Wilson action with two degenerate sea-quark flavours. We describe our implementation of the algorithm on the Cray-T3E, concentrating on issues arising from code verification and performance optimisation, such as parameter tuning, ...

results using these two sets, we identified h1069q mutation in four patients, c.2335t > g mutation in three, c.3061-1g > a splice site mutation in five, c.3305t > c mutation in one, and c.3809a > g mutation in two patients. conclusions the multiplex arms assay used in this study can be an efficient, reliable, and cost effective method as a primary screen for patients with wilson disease. patien...

A non-parametric multi-resolution method is presented for cell segmentation and some of the advantages it has over other techniques, when applied to this application, are outlined. The proposed algorithm is an extension on the method of Wilson and Spann 6] and uses a technique based on the concept of water immersion which ensures closed boundaries. Experiments with cervical cells have shown tha...

A hybrid algorithm is proposed for pure SU(N) lattice gauge theory based on Genetic Algorithms (GA)s and the Metropolis method. We apply the hybrid GA to pure SU(2) gauge theory on a 2-dimensional lattice and find the action per plaquette and Wilson loops being consistent with those given by the Metropolis and Heatbath methods. The thermalization of this newly proposed Hybrid GA is quite faster...
