Large-eddy simulations of a pocket of open cells (POC) based on VOCALS Regional Experiment (REx) Research Flight 06 are analyzed and compared with aircraft observations. A doubly-periodic domain 192 km×24 km with 125 m horizontal resolution and 5 m vertical resolution near the capping inversion is used. The POC is realized in the model as a fixed 96 km wide region of reduced cloud droplet numbe...

BACKGROUND : Allergy is a serious problem affecting approximately 1 of 4 individuals. The symptoms with and without allergy etiology are often difficult to distinguish from each other without using an IgE antibody test. The aim of this study was to investigate the performance of a new point-of-care (POC) test for IgE antibodies to relevant allergens in Europe. METHODS : IgE antibodies from ch...

BACKGROUND Pentalogy of Cantrell (POC) is an extremely rare and complex congenital anomaly. Ultrasound is a valuable, safe, nonionizing, cost effective, widely available, and easily reproducible imaging tool and is indispensible in the diagnosis of POC. Despite the rarity of POC, it is imperative for a radiologist to be aware of its wide spectrum of presentation on ultrasound in first trimester...

BACKGROUND Clinical microbiology may direct decisions regarding hospitalization, isolation and anti-infective therapy, but it is not effective at the time of early care. Point-of-care (POC) tests have been developed for this purpose. METHODS AND FINDINGS One pilot POC-lab was located close to the core laboratory and emergency ward to test the proof of concept. A second POC-lab was located ins...

Background: Human papillomavirus is the most prevalent sexually transmitted infection in the United States and is associated with 70% of cervical cancers as well as over 90% of genital warts. Although the HPV vaccine appears in the US immunization schedule during adolescence, a large percentage of women reach adulthood without being vaccinated. The Transtheoretical Model’s (TTM) Processes of Ch...

A lthough most diabetes management guidelines (1–3) suggest that physicians measure A1C, it is extremely difficult to have results available before a physician’s evaluation of the patient. As such, point-of-care (POC) A1C is thought to be useful since it is assumed that rapid result availability will enhance diabetes care by increasing education and ensuring appropriate changes to therapy while...

A long time-series study was conducted over 15 yr (1989–2004) to measure particulate organic carbon (POC) flux as an estimate of food supply reaching .4,000-m depth in the northeast Pacific. Sequencing sediment traps were moored at 3,500-and 4,050-m depth, 600 and 50 m above the seafloor, respectively, to collect sinking particulate matter with 10-d resolution. POC fluxes were compared with thr...

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...
