The phrase "a more precise characterization" is correct and usable in written English.
It can be used when you want to describe something in a clearer or more accurate way than before.
Example: "In order to improve our understanding of the phenomenon, we need a more precise characterization of its underlying mechanisms."
Alternatives: "a clearer description" or "a more accurate depiction".
To better understand and exploit microRNA (miR) regulation, a more precise characterization of miR expression patterns within a tissue or a lineage during development, differentiation, and homeostasis is needed.
If focusing on a specific data model, a more precise characterization of completeness can be given.
To narrow down a more precise characterization of acute flaccid myelitis, Matthew J. Elrick, MD, PhD, of the Johns Hopkins University School of Medicine Department of Neurology, and his colleagues looked back at cases diagnosed in children between 2012-2016.
No matter what exactly the facts about the metaphysics of memory and the analysis of remembering are, we will need a more precise characterization of the notion of a memory belief before we can proceed.
Furthermore, a real implementation in a software-defined-radio (SDR) platform will enable a more precise characterization of the true system performance, by carefully considering the synchronization related issues.
Although very useful for taxonomic, physiological and genetic studies, culture-based techniques are insufficient for a more precise characterization of the functional and phylogenetic diversity of microbial communities, since it is now well known that only a small fraction (0.1 to 10%) of the microbial diversity in nature can be recovered in the laboratory (Torsvik et al. 1990; Amann et al. 1995).
Tremendous advances in surface characterization and solids analysis has allowed a more precise picture of the active sites to be gained.
The superior characterization of soft tissues and better visualization of tumour extent may be benefecial for radiotherapy planning because a more precise delineation of margins for the organ sparing strategies with boosting and dose escalation is feasible.
Although previous studies also have identified an increased risk of CVD associated with IFG (100 125 mg/dL) (3, 5, 28, 29), the size of KCPS provides a much more precise characterization of the up-turn in risk in relation to blood glucose level, placing it at ∼90 mg/dL.
More precise characterization of stem cells with identification of new, unique markers; improvement in isolation and transplant techniques; and further development of functional assays will ultimately lead to new therapies for a host of human lung diseases.
