The performance of grant-free random access (GF-RA) is limited by the number accessible resources (RRs) due to absence collision resolution. Compressive sensing (CS)-based RA schemes scale up RRs at expense increased non-orthogonality among transmitted signals. This paper presents design multi-sequence spreading (MSRA) which employs multiple sequences spread different symbols a user as opposed ...

OBJECTIVE To explore the causes of failure to activate the rapid response system (RRS). The organisation has a recognised incidence of staff failing to act when confronted with a deteriorating patient and leading to adverse outcomes. DESIGN A multi-method study using the following: a point prevalence survey to determine the incidence of abnormal simple bedside observations and activation of t...

BACKGROUND AND AIMS Clinical observations suggest that the lymphoid follicles (LFs) may play a crucial role in the pathogenesis of inflammatory bowel disease (IBD), especially in Crohn's disease (CD) as the site of initial mucosal inflammation. The aim of this study was to compare the morphology of LFs in CD, ulcerative colitis (UC) and control patients using confocal laser endomicroscopy (CLE)...

BACKGROUND Health care decision makers often need to make decisions in limited timeframes and cannot await the completion of a full evidence review. Rapid reviews (RRs), utilizing streamlined systematic review methods, are increasingly being used to synthesize the evidence with a shorter turnaround time. Our primary objective was to describe the processes and methods used internationally to pro...

The pattern of lung emptying was studied in 10 mechanically-ventilated patients with acute respiratory distress syndrome. At four levels of positive end-expiratory pressure (PEEP) (0, 5, 10 and 15 cmH2O) tracheal (Ptr) and airway pressures (Paw), flow (V') and volume (V) were continuously recorded. Tidal volume was set between 0.5-0.6 L and V'/V curves during passive expiration were obtained. E...

PCR amplicons enlarged by approximately 250bp were generated from the 16S rRNA (rrs) genes of certain strains of the recently described Helicobacter species, H. canis. The DNA sequence of the rrs gene of one such strain was determined, and it was shown that an intervening sequence (IVS) of 235bp followed nucleotide 199 in the rrs sequence. In four other H. canis strains, identical or similar IV...

BACKGROUND Few studies have examined the effects of paternal and maternal history of myocardial infarction (MI), including age at MI, on cardiovascular disease (CVD) risk, particularly among women. METHODS AND RESULTS We prospectively studied 22 071 men from the Physicians' Health Study and 39 876 women from the Women's Health Study with data on parental history and age at MI. Among men, 2654...
