The phrase "a more precise characterisation" is correct and usable in written English.
It can be used when discussing the need for a clearer or more accurate description of something.
Example: "In order to improve our understanding of the phenomenon, we require a more precise characterisation of its underlying mechanisms."
Alternatives: "a clearer description" or "a more accurate depiction".
For a more precise characterisation of the mechanisms governing these differences in IL-12 secretion between neonates and adults, we needed to identify the principal cell population responsible for secreting this cytokine in the neonatal MLN.
Our study provides a more precise characterisation of this variability and confirms that exposure to treatment differs considerably among individuals.
Such molecular methods allow a more precise characterisation of isolated C. difficile strains, e.g. ribotype differentiation [ 35, 106, 107].
For a more precise characterisation of the properties of the new PAs, the micelle size, shape and micelle building concentration were determined.
Such a comparison with the growth rate influence would have allowed a more precise characterisation of the general stress response in the yeast.
Indeed, the use of clinical records permits a far more precise characterisation of events preceding diagnosis than is possible in studies that rely on self-report (Simpson et al, 2007).
There is a need for more precise characterisation of samples and for greater homogeneity of samples in research studies in this field.
It is perhaps timely to re-appraise earlier data on apoptosis and involution in light of recent technological advances that have allowed more precise characterisation of the process.
In future more precise characterisation of the tumour by genetic tests and surveillance with MRI may enable earlier detection than routine mammography.
More precise characterisation of the nature and location of focal FDG accumulations identified by PET by comparison with a contemporaneous CT is likely to further improve diagnostic performance and thereby, treatment selection and planning.
The paper goes on to argue that thinking about animal consciousness in this way helps in formulating a more precise functional characterisation of the mechanisms of conscious awareness.
