Previous Medical Research

  • Patient-reported toxicity levels after radical cancer therapy CTCAE questionnaires, QoL via EORTC QLQ C30 questionnaire, anxiety and depression via HADS questionnaire (The Christie, Manchester). (Currently) EAGLE study at Cardiff University for prostate cancer. See The Christie Scoring Website.
  • MRC "Statistical Calibration" project at the Health Methodology Research Group, University of Manchester. See, e.g., NCRM e-print on "Cross measure calibration methods and how they can enhance our analytical potential" by A. Pickles, D.J.J. Farnell, and C. Roberts: http://eprints.ncrm.ac.uk/2806/.
  • Automated Retinal Image Analysis (ARIA) project principal researcher for the ARIA project at St. Paul's Eye Unit, RLUHT. Recruitment of patients, retinal photography, and image analysis of resulting digital fundus photographs. See my article: Enhancement of blood vessels in digital fundus photographs via the application of multiscale line operators.
  • Monte Carlo simulations of photon transport in human tissues (previously), i.e., prediction of iris-colour changes in glaucoma patients after treatment by a topical prostaglandin drug called Latanoprost (St. Paul’s Eye Unit, Liverpool). See our published journal article in this topic.
  • OSTEODENT project prediction of osteoporosis and osteopenia from image analysis of panoramic mandibular radiograms.
  • Strongly coupled fluid/structure interactions i.e., “how do fish swim, flags flap, and hearts beat?”

CCCM crystallographic coupled cluster method

  • CCCM is a high-order CCM (coupled cluster method) code for lattice spin systems at T=0 by Damian J. J. Farnell (DF).
  • Historically, this code is based on "foundations" laid by Ray Bishop and John Parkinson (amongst others), and Chen Zeng's work in the 90's on the high-order code.
  • This code has been exploited and pushed forward by Damian Farnell and Sven Krüger primarily.
  • Joerg Schulenburg (JS) improved this code greatly and he has set up this webpage for distribution of the most recent code.
