The push-to-talk technology provides a walkie-talkie like service for group communication. In this paper, we propose an efficient outbound voice traffic reduction scheme in the push-to-talk environment when network congestion happens. The Open Mobile Alliancepush-to-talk over cellular (OMA PoC) architecture, the standard for this kind of group communication, is used as a base network in this pa...

Point-of-care (POC) HIV testing has been shown to be an acceptable method for increasing HIV testing uptake. To date, no studies have examined the use of POC testing for routine HIV screening on the medicine inpatient unit. A prospective cross-sectional study was conducted over a three-month period in July, August, and October 2016 to evaluate the prevalence of undiagnosed HIV and the attitudes...

Human immunodeficiency virus (HIV) is a global health problem. Early diagnosis, rapid antiretroviral therapy (ART) initiation and monitoring of viral load are the key strategies for effective HIV management. Many people in resource limited settings where timely access to medical care is a challenge and healthcare infrastructure is poor have no access to laboratory facilities and diagnosis is de...

Point-of-care (POC) laboratories that deliver rapid diagnoses of infectious diseases were invented to balance the centralization of core laboratories. POC laboratories operate 24 h a day and 7 days a week to provide diagnoses within 2 h, largely based on immunochromatography and real-time PCR tests. In our experience, these tests are conveniently combined into syndrome-based kits that facilitat...

The research work is carried out to enhance the recognition accuracy of neural network with Phase Only Correlation (POC) and reduce the time required for POC by refining its input. In this research work neural network has not been directly used for recognition but for the minimization of the search space. The fusion of neural network with POC is tested on face recognition application to validat...

In this paper we investigate the ratio of the connected vertex cover number to the vertex cover number in graphs, called the Price of Connectivity (PoC). For general graphs, this ratio is strictly bounded by 2. We prove that for every (P5, C5, C4)-free graph the ratio equals 1. We prove also that for every (P5, C4)-free graph the ratio is bounded by 4/3 and that for every (P7, C6,∆1,∆2)-free gr...

Accurate monitoring of glucose in the perioperative environment has become increasingly important over the last few years. Because of increased cost, turnaround time, and sample volume, the use of central laboratory devices for glucose measurement has been somewhat supplanted by point-of-care (POC) glucose devices. The trade-off in moving to these POC systems has been a reduction in accuracy, e...

A1C point-of-care (POC) instruments benefit patients with diabetes by facilitating clinician decision making that results in significant glycemic improvements. Three National Glycohemoglobin Standardization Program (NGSP)-certified POC products are available in the United States: the handheld A1CNow (formerly manufactured by Bayer Diabetes Care but now made by Chek Diagnostics) and two bench-to...

This paper reviews 14 published studies describing performance characteristics, including sensitivity and specificity, of commercially available rapid, point-of-care (POC) influenza tests in patients affected by an outbreak of a novel swine-related influenza A (H1N1) that was declared a pandemic in 2009. Although these POC tests were not intended to be specific for this pandemic influenza strai...

A major fraction of particulate organic carbon (POC) in the deep ocean remains molecularly uncharacterized. In an effort to determine the chemical characteristics and source(s) of sinking POC, we studied a nonhydrolyzable fraction of sinking POC using C NMR (nuclear magnetic resonance) spectroscopy and analytical pyrolysis. C NMR spectra and products from analytical pyrolysis of the nonhydrolyz...
