The PoC (Push-to-talk over Cellular) application allows point-to-point, or point-to-multipoint voice communication between mobile network users. The related work over PoC focuses on the performance analysis only and is completely ignorant about dimensioning PoC controller to optimize revenue for service providers. In this paper, we dimension a PoC controller with the assumption that the network...

The Veterans Health Administration is implementing a pragmatic trial research program, called Point of Care Research (POC-R). The purpose of this telephone survey in which respondents were randomized to different framing conditions of the purpose of POC-R was to determine the impact of differing frames of the purpose of POC-R on attitudes towards the program and intentions to participate; and t...

We present a theoretical analysis of one-time key based phase scrambling for image matching using phase-only correlation (POC). Phase scrambling is used for visual information protection of templates. The effect of scrambling on POC values is analyzed. As a result, the peak value, which is used as a measure of signal congruence, of the POC between nonscrambled signals can be estimated by observ...

We describe a novel approach to process bioceramic microparticles and poly(diol citrates) into bioceramic-elastomer composites for potential use in orthopedic surgery. The composite consists of the biodegradable elastomer poly(1,8-octanediol-citrate) (POC) and the bioceramic hydroxyapatite (HA). The objective of this work was to characterize POC-HA composites and assess the feasibility of fabri...

A two step approach was developed to estimate POC concentrations in a shallow eutrophic lake, where dissolved carbon and inorganic particulate matter strongly influence optical properties. The approach was based on the identification of a co-variability of POC concentrations with one or more inherent optical properties (IOPs). In the present case, a relationship between POC and absorption at 62...

INTRODUCTION Key stakeholders' involvement is crucial to the sustainability of quality point-of-care (POC) diagnostics services in low-and-middle income countries. The aim of this study was to explore key stakeholder perceptions on the implementation of POC diagnostics in rural primary healthcare (PHC) clinics in South Africa. METHOD We conducted a qualitative study encompassing in-depth inte...

A study was carried out to determine the quality characteristics, antioxidant capacity, oxidative status, and consumer acceptability of chicken meat after dietary administration of a semi-solid olive cake, known as “paté” (pOC), in broilers. pOC is an olive oil industry waste rich in bioactive compounds, such as polyphenols, obtained by mechanical extraction from destoned olives. Two hundred an...

In situ measured values of particulate organic carbon (POC) in Taihu Lake and remote sensing reflectance observed by three satellite courses from 2014 to 2015 were used to develop an near infrared-red (NIR-Red) empirical algorithm of POC for the Moderate Resolution Imaging Spectroradiometer (MODIS-Aqua) satellite image. The performance of the POC algorithm is highly consistent with the in situ ...

Antibiotic resistance is threatening to make gonorrhoea untreatable. Point-of-care (POC) tests that detect resistance promise individually tailored treatment, but might lead to more treatment and higher levels of resistance. We investigate the impact of POC tests on antibiotic-resistant gonorrhoea. We used data about the prevalence and incidence of gonorrhoea in men who have sex with men (MSM) ...

OBJECTIVES To compare the effectiveness and cost-effectiveness of a promising new point-of-care (POC) chlamydia test with traditional nucleic acid amplification testing (NAAT), and to determine the characteristics that would make a POC test most cost-effective. METHODS A decision tree was constructed to model chlamydia screening visits to a sexually transmitted disease clinic by a hypothetica...
