In systematic reviews, the growing number of published studies imposes a significant screening workload on reviewers. Active learning is a promising approach to reduce the workload by automating some of the screening decisions, but it has been evaluated for a limited number of disciplines. The suitability of applying active learning to complex topics in disciplines such as social science has no...

We validated a commercial enzyme-linked immunosorbent assay (ELISA), Helico-G, in diagnosing H. pylori in 129 patients (mean age 50 years, range 15-86). We analysed the results of endoscopy against serology to see whether there was a possibility of adopting the strategy of not endoscoping dyspeptic subjects under the age of 45. H. pylori infection was considered present if either histology and/...

Runtime leakage control is gaining in importance, and recent work has demonstrated the possibility of reducing leakage via synthesis and post-synthesis optimizations. These techniques utilize the leakage dependence on state vectors and synthesis the circuit that minimizes power of the most-likely circuit configuration using state probabilities. In this paper we provide empirical evidence using ...

Over the past decade, cloud computing services become pervasive in the industrial field in order to enhance the efficiency and reduce the TCO (Total Cost of Ownership). Virtual desktop infrastructure (VDI) provides the computing environment to the client, where the host server delivers the video images encoded on the host server. The client decodes the video images and then displays them on the...

Introduction Information visualization techniques aim to help the users deal with voluminous information by reducing their mental workload. However, the visualization techniques themselves often cause an adverse effect on the users. Instead of reducing information overload, they impose yet another mental workload due to the complexity in the visual data they try to visualize as well as the grap...

BACKGROUND Burnout has been implicated as one of the reasons for key healthcare personnel, such as nurses, leaving their profession, resulting in insufficient staff to attend to patients. OBJECTIVE We investigated the predictors of three dimensions of burnout, namely emotional exhaustion, depersonalisation and personal accomplishment, among nurses in South Africa attending to patients living ...

Several projects involving high-level thermal management — such as eliminating “hot spots” or reducing cooling costs through intelligent workload placement — require ambient air temperature readings at a fine granularity. Unfortunately, current thermal instrumentation methods involve installing a set of expensive hardware sensors. Modern motherboards include multiple on-board sensors, but the v...
