BACKGROUND The LACE index has been used to predict the risk of unplanned readmission within 30 days after hospital discharge in both medical and surgical patients. The aim of this study is to validate the accuracy of using the LACE index in CHF patients. METHODS This was a retrospective study. The LACE index score was calculated on each patient who was admitted to hospital due to an acute CHF...

OBJECTIVE To assess how well the LACE index and its constituent elements predict 30-day hospital readmission, and to determine whether other combinations of clinical or sociodemographic variables may enhance prognostic capability. DESIGN Retrospective cohort study with split sample design for model validation. SETTING One large hospital Trust in the West Midlands. PARTICIPANTS All alive-d...

BACKGROUND Significant effort has been directed at developing prediction tools to identify patients at high risk of unplanned hospital readmission, but it is unclear what these tools add to clinicians' judgment. In our study, we assess clinicians' abilities to independently predict 30-day hospital readmissions, and we compare their abilities with a common prediction tool, the LACE index. METH...

Portion of a Landsat TM scene (Bands 3, 2, 1 as RGB) with normalized contrast enhancement. Dark lava flows and bright salt flats reveal little local detail. Same scene with the RGB LACE filter applied with Normalized input redistribution. The final image is a weighted average of the LACE filter output (90%) and the original image (10%). Enhanced contrast in dark and light areas brings out signi...

Over 60 Pieris taxa (Ericaceae) were measured for their susceptibility to the Andromeda lace bug, Stephanitis takeyai Drake and Maa, and the azalea lace bug, Stephanitis pyrioides (Scott) (Hemiptera: Tingidae) based on leaf damage, adult survival on leaves, and emergence of nymphs in no-choice petri dish assays. Pieris phillyreifolia (Hook.) DC. and P. japonica (Thunb.) D.Don ex G.Don 'Variega...

David Brydges and Thomas Spencer's Lace Expansion is abstracted, and it is shown how it sometimes gives rise to sieves. LACES Definition: Let P be a finite set of properties. A mapping l that assigns to any subset S ⊂ P another subset l(S), is called a lace-map, A set L for which l(L) = L is called a lace. By applying (ii) to G = l(S), it is seen that l(l(S)) = l(S), for any set of properties S...

The lace expansion has been used successfully to study the critical behaviour in high dimensions of self-avoiding walks, lattice trees and lattice animals, and percolation. In each case, the lace expansion has been an expansion along a time interval. In this paper, we introduce the lace expansion on a tree, in which ‘time’ is generalised from an interval to a tree. We develop the expansion in t...

Work-stealing is an efficient method to implement load balancing in fine-grained task parallelism. Typically, concurrent deques are used for this purpose. A disadvantage of many concurrent deques is that they require expensive memory fences for local deque operations. In this paper, we propose a new non-blocking work-stealing deque based on the split task queue. Our design uses a dynamic split ...
