Several lines of evidence support the involvement of the disrupted in schizophrenia 1 (DISC1) gene in schizophrenia susceptibility, including its original identification in a schizophrenia family with a chromosome translocation, several genetic association studies, and functional characterization of the gene product. In the present study, we have genotyped(More)
Two experimental systems for query based visual analysis are described. The first simulates an image sequence of moving, dividing cells with simple rules and monitors significant visual events. The second processes single raw images of real cells. Both invoke appropriate processing using explicit knowledge to respond to user queries. We propose that this(More)
The UK has an abundant offshore wind resource with offshore wind set to grow rapidly over the coming years. Optimisation of energy production is of the utmost importance given the high installation and maintenance costs of offshore turbines; accurate estimates of wind speed characteristics are critical during the planning process. While operational(More)
Lie algebraic methods are described which were used to optimize the d~ign of the PEP-II lattices. These methods include calculation of the nonlinear Hamiltonian for lattice modules, dimensionless normalized representation of resonance basis coefficients, correlation of coefficients with dynamic aperture determination, and techniques for coefficient control(More)
