An instrument for the simultaneous acquisition of size, shape, and spectral fluorescence data from single aerosol particles.
Hirst, E; Kaye, Paul H.; Foot, V; Clark, J M; Withers, P B (SPIE, 2004)We describe the construction of a bio-aerosol monitor designed to capture and record intrinsic fluorescence spectra from individual aerosol particles carried in a sample airflow and to simultaneously capture data relating ... -
Integrating genomic binding site predictions using real-valued meta classifiers
Sun, Yi.; Robinson, M.; Adams, R.G.; Kaye, Paul H.; Te Boekhorst, R.; Rust, A.G.; Davey, N. (2009)Currently the best algorithms for predicting transcription factor binding sites in DNA sequences are severely limited in accuracy. There is good reason to believe that predictions from different classes of algorithms could ... -
