Department of Geography, Miami University, Oxford, OH 45056 ([email protected]). Abstract Remote sensing techniques have been widely used to map fire scars in the western United States, but have not been thoroughly tested in the eastern portion of the country. In this study, a 1998 Landsat Thematic Mapper (TM) image and a 1999 Enhanced Thematic Mapper (ETM1) image were used to test different i...
This Paper aims at classification of flower images by means of Gist descriptor and statistical features using SVM classifier. With advances in digital image processing, automated classification of flower images over large categories of dataset is possible by knowing the name of the flower. In case of unknown species name, classification of flower image can be performed by its visual content. Th...
To study the predictive value of biopsy lesions in IgA nephropathy in a range of patient ages we retrospectively analyzed the cohort that was used to derive a new classification system for IgA nephropathy. A total of 206 adults and 59 children with proteinuria over 0.5 g/24 h/1.73 m(2) and an eGFR of stage-3 or better were followed for a median of 69 months. At the time of biopsy, compared with...

BACKGROUND IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide, leading to renal failure in 15% to 40% of cases. IgAN is diagnosed by renal biopsy, an invasive method that is not risk-free. We used blood and urine peptide profiles as a noninvasive method of linking IgAN-associated changes with histological lesions by Oxford classification. METHODS We prospectively s...
The authenticity of much of the stone-work along Queen’s Lane in central Oxford, UK presented an opportunity to produce a photographic survey from which a weathering index could be established. This represents a site-specific approach to devising a weathering form. Because it is photo-based, weathering forms are visible for comparison and classification purposes across disciplines. Limestone pe...

The aim of this paper is to leverage foreground segmentation to improve classification performance on weakly annotated datasets – those with no additional annotation other than class labels. We introduce TriCoS, a new co-segmentation algorithm that looks at all training images jointly and automatically segments out the most class-discriminative foregrounds for each image. Ultimately, those fore...
BACKGROUND The Oxford classification of IgA nephropathy (IgAN) provides a useful tool for prediction of renal prognosis. However, the application of this classification in children with IgAN needs validation in different patient populations. METHODS A total of 218 children with IgAN from 7 renal centers in China were enrolled. The inclusion criteria was similar to the original Oxford study. ...
BACKGROUND The present review is aimed to evaluate the correlation between pathological features and the response to steroid in the patients with IgA nephropathy according to the Oxford classification, mesangial hypercellularity (M), endocapillary hypercellularity (E), segmental glomerulosclerosis (S), tubular atrophy and interstitial fibrosis (T). METHODS We searched Chinese Biomedical Datab...
