With the development of database, multimedia and computer vision technology, content-based image retrieval (CBIR) technology has been a hot topic in recent years. Texture image retrieval is an important part of CBIR. In this paper, a new 2614 Jiming Lan et al method for texture image retrieval based on nonsubsampled contourlet transform (NSCT) and matrix F-norm is proposed. The experimental res...

Lead (Pb) intoxication in horses is usually a chronic phenomenon with clinical signs associated with central nervous dysfunction. This report gives details of a case of acute Pb intoxication in a 9-year-old American Saddlebred mare with severe, progressive and ultimately fatal neurological deterioration. During the 4 days of hospitalisation, clinical signs progressed from intermittent headshaki...

Excitons in an infinite layered dipolar medium, such as a layered molecular crystal or a multiple-quantum-well stack, with perfect periodicity exhibit a vanishing radiative width due to the requirement of energy-momentum conservation. Using a pola&on model with off-diagonal disorder and a configuration-averaging technique, we show how deviations from the ideal case, specifically in the form of ...

Two papers in the Journal this month examine patterns of prescribing practice. With established clinical guidelines for the management of individuals with treatment-resistant schizophrenia in mind, Howes et al (pp. 481–485) reviewed prescribing practices prior to commencement of clozapine for a sample of patients managed within one mental health service. The authors found evidence of a signific...

We have previously reported that, depending on their activation status, mouse γδ T cells can either enhance or inhibit the activity of IL-17(+) autoreactive T cells in experimental autoimmune uveitis. In this study, we showed that γδ T cells in naive C57BL/6 (B6) mouse do not express the IL-23R, whereas in immunized mice, it is expressed on >50% of γδ T cells. In vitro studies showed that IL-23...
