We thank Chris Bulpitt, Dee Jones, and Alistair Tulloch, co-investigators on the MRC trial of assessment and management of older people, and the nurses, GPs, the other staff and the patients in the participating practices: the MRC General Practice Research Framework Co-ordinating Centre (Madge Vickers, Jeannett Martin, and Nicky Fasey); the research team for the MRC trial of assessment and mana...

The Rayleigh conjecture about convergence up to the boundary of the series representing the scattered field in the exterior of an obstacle D is widely used by engineers in applications. However this conjecture is false for some obstacles. AGR introduced the Modified Rayleigh Conjecture (MRC), which is an exact mathematical result. In this paper we review the theoretical basis for the MRC method...

To investigate the effects of HIV infection on mitochondrial DNA (mtDNA) content and other mitochondrial parameters, we used peripheral blood mononuclear cells (PBMCs) from 25 asymptomatic antiretroviral-naive human immunodeficiency virus (HIV)-infected patients and from 25 healthy control subjects. HIV-infected patients had significant decreases in mtDNA content (decrease, 23%; P<.05) and in t...

In this letter, we evaluate the performance of multicarrier code division multiple access (MC-CDMA) in terms of average bit error probability (BEP) in Nakagami fading channels. The results are applicable to MC-CDMA systems employing coherent demodulation with maximal-ratio combining (MRC) or equal gain combining (EGC) reception. The effects of fading parameters and number of users are presented...

In this paper, we derive bit error performance bounds for turbo codes on Nakagami fading channels with diversity combining. We first derive the average pairwise error probability expressions for turbo codes with maximal ratio combining (MRC), equal gain combining (EGC), and selection combining (SC) on Nakagami fading channels. Using the pairwise error probability expressions and the union bound...

BACKGROUND Severity of chronic obstructive pulmonary disease (COPD) is based either on symptoms/disability or lung function, which have no discernible correlation. We hypothesised that impulse oscillometry (IOS), a non-effort-dependent measure of central and peripheral airway mechanics, could correlate to dyspnoea in COPD. METHODS We analysed screening data from 57 COPD patients who had spiro...

Purpose / introduction Magnetic Resonance Colonography (MRC) is studied as screening technique for colorectal cancer. The lack of ionizing radiation and the superior contrast resolution over computed tomography (CT) make MRC a valuable alternative to CT-colonography [1]. At present the optimal scan parameters and bowel preparation, aimed at high image quality and minimized patient burden, are n...

Maximally recoverable codes are a class of which recover from all potentially erasure patterns given the locality constraints code. In earlier works, these have been studied in context with locality. The notion has extended to hierarchical locality, allows for gradually increase levels number erasures. We consider imposed by two-level and define maximally characterize set can be corrected data-...

Machine reading comprehension (MRC) is a type of question answering mechanism in which computer reads documents and answers related questions. The accuracies recent MRC systems surpass those humans. However, most exhibit significant performance deteriorations when domains are changed. Hence, we propose self-training framework for MRC. proposed composed pseudo-answer extractor, pseudo-question g...

PURPOSE The aim of this study was to evaluate the usefulness of magnetic resonance cholangiography (MRC) for the diagnosis of biliary atresia in infantile cholestatic jaundice. METHODS Forty-seven consecutive infants with cholestatic jaundice underwent single-shot MRC. The diagnosis of biliary atresia was made by MRC based on the nonvisualization of extrahepatic bile ducts and excluded on the...
