Current proposals for XML change detection use structural constraints to detect the changes and they ignore semantic constraints. Consequently, they may produce semantically incorrect changes. In this paper, we argue that the semantics of data is important for change detection. We present a semantic-conscious change detection technique for the hidden web data. In our approach we transform the u...

Background: A number of microorganisms and their enzymes have been reported as xanthan depolymerizers. Paenibacillus species are well-known polysaccharide hydrolyzing bacteria. However, Paenibacillus alginolyticus and Paenibacillus sp.XD are the only species in the genus which are now known to degrade xanthan.Objectives: Complete biodegradation of the xan...

Background – We have previously demonstrated opposite e¡ ects of exercise training in stable and progressive pulmonary hypertension (PH). Here we investigated cellular changes which may underlie the opposite e¡ ects of exercise training by focusing on right ventricular myolament protein phosphorylation and function. Methods and results – Histological analyses revealed exercise training in progr...

838 www.thelancet.com/neurology Vol 11 October 2012 Use of brain imaging to predict treatment response after ischaemic stroke, a test of which is reported by Maarten Lansberg and colleagues in this issue of The Lancet Neurology, has a long history. In 1993, Gilles Marchal and colleagues used information about both blood fl ow and metabolic activity obtained with PET to predict diff erential cli...

OBJECTIVE To assess the sensitivity, specificity and accuracy of Diff-Quik, fungifluor stain, the direct immunofluorescence test (DIFT) and the polymerase chain reaction (PCR) in the diagnosis of Pneumocystis carinii pneumonia (PCP) in human immunodeficiency virus (HIV)-infected patients. STUDY DESIGN From December 1992 through November 1993, 112 bronchoalveolar lavage fluid (BALF) samples we...

This paper describes the design philosophy behind the recent replacement of the NAG Ordinary Di erential Equation (ODE) sti integrators. This replacement was is intended to update the ODE chapter algorithmically but, more importantly in the context of this paper, it provides a more exible interface than has been available in the past. This interface is designed to permit a wide variety of probl...
