The latter two options can be implemented using VGI data that were obtained from a non-probability sampling design, but require additional sample data to be acquired via a probability sampling design.
As more targeted treatment options become available, testing for multiple markers is required and abundant, good quality samples need to be acquired [12].
Serum markers for cancer status are being tracked by researchers [ 78, 79] since the serum samples are easier to be acquired than tissue samples, yet few markers have proved to be clinically useful so far.
First, it saves energy by reducing the number of samples that have to be acquired, processed, and communicated thus increasing the lifetime of the network.
For fluorescence images, when samples to be compared were acquired using different exposure times, data were normalized to exposure time using the normalized counts setting/function in inForm.
To monitor the conversion reaction of oils to biodiesel, samples were acquired at different times during TE of rapeseed oil, and measured using relaxation time distribution experiments to track the progression of this reaction until completion.
Determining whether a sufficient number of samples has been acquired is hard to assess, and in practical situations only non-convergence can be diagnosed (Cowles and Carlin, 1996).
Blood samples were acquired to evaluate hormonal concentrations, and premenstrual symptoms were assessed through daily record of severity of problems questionnaires.
Pigment reference samples were acquired in order to confirm spectral characterizations and to construct model samples of paint mixtures.
The samples were acquired according to the institutional guidelines of the research ethics board of the University Health Network Research Ethics Board (Toronto, Canada).
