Urine samples were measured for cGMP concentrations using a scintillation proximity method.
The proximity method, also known as cell of origin (CoO), consists in detecting an entity presence inside a limited area, or cell, in which coordinates are known.
One approach to localization is the proximity method, which is easy to implement and is less affected by dynamic changes in the environment.
Based on this review, the paper summarizes the intensive use of the proximity method in RFID-based ILS, and analyzes the underlying rationale.
The technique described in this study is a new acoustic proximity method that has demonstrable potential for providing spatial and temporal information regarding the composition and structure of marine animal groups.
First, the use of a proximity method for exposure classification is subject to misclassification bias.
The sampling of households was done by spin-the-bottle and proximity method.
In Masisi and Kitchanga, two-stage cluster sampling was used following the standard World Health Organisation (WHO) Expanded Programme on Immunization cluster sampling proximity method[ 7].
In a comparative study, the kinetic parameters of TcNMT (5 nM per assay) were also determined using a scintillation proximity method, as described previously [ 13, 29].
Toward this end we are investigating several ranking strategies ranging from traditional term weighting approach to a recently proposed term proximity method (80).
