Active Appearance Models (AAMs) are widely used to fit shape models to new images. Recently it has been demonstrated that non-linear regression methods and sequences of AAMs can significantly improve performance over the original linear formulation. In this paper we focus on the ability of a model trained on one dataset to gen-eralise to other sets with(More)
Arbutin (hydroquinone-beta-D-glucopyranoside) is present in various food plants. Its aglycone, hydroquinone, is mutagenic and carcinogenic. We investigated whether hydroquinone may be released under conditions encountered in the human gastrointestinal tract. Arbutin was stable in artificial gastric juice. Fecal slurries from nine human subjects completely(More)
The Active Appearance Model (AAM) provides an efficient method for localizing objects that vary in both shape and texture, and uses a linear regressor to predict updates to model parameters based on current image residuals. This study investigates using additive (or 'boosted') predictors, both linear and non-linear, as a substitute for the linear predictor(More)
OBJECTIVE To document changes in antibiotic resistance of organisms in cases of equine bacterial ulcerative keratitis over a 10-year time period. DESIGN A retrospective study. PARTICIPANTS Medical records of equine patients with bacterial ulcerative keratitis seen at the University of Florida's VMTH for the years 1991-2000 were reviewed. MATERIALS AND(More)
High-pressure is a key feature of deep subsurface environments. High partial pressure of dissolved gasses plays an important role in microbial metabolism, because thermodynamic feasibility of many reactions depends on the concentration of reactants. For gases, this is controlled by their partial pressure, which can exceed 1 MPa at in situ conditions.(More)
Terrestrial mud volcanoes (TMVs) represent geochemically diverse habitats with varying sulfur sources and yet sulfur cycling in these environments remains largely unexplored. Here we characterized the sulfur-metabolizing microorganisms and activity in four TMVs in Azerbaijan. A combination of geochemical analyses, biological rate measurements and molecular(More)
The diierential coincident pion electroproduction cross section in the 3 He(e,e 0 +) 3 H reaction has been measured with high resolution with the three-spectrometer setup at the Mainz Microtron (MAMI) electron accelerator. 1 Measurements were performed at the four incident energies E 0 = 855; 675; 600; and 555 MeV at xed four-momentum transfer Q 2 = 0.045(More)
