As much as the heterogeneity poses quantitative difficulties, it is unavoidable because the population of diabetic patients is heterogeneous when we account for treatment duration, compliance, and lifestyle, among other factors, which may result in very different risks of hypoglycaemia.
Rare codons are capable of causing qualitative and quantitative expression difficulties [ 9, 10].
However, researchers of these subsequent community-based quantitative studies had difficulty obtaining female participants (Moser & Levitt, 1987; Sandnabba, Santtila, & Nordling, 1999).
In the present study, by using insertion time as a surrogate and quantitative endpoint of difficulty, four independent variables, including age, BMI, case volume of colonoscopists and sleep quality were identified as high-risk factors associated with intubation difficulty.
However, the inherent complexity of quantitative IHC poses difficulties for reliable translation of markers into the clinic and despite significant advances in the development and application of image analysis in recent years, a number of challenges remain to be addressed.
The paper briefly touches on the international, academic role of English, outlines its contemporary role in universities in the People's Republic of China and then describes a small quantitative study of student difficulty with specialist English that illustrates the impact of those difficulties on text accessibility.
Due to the lack of exact quantitative information or the difficulty associated with obtaining or processing such information, qualitative spatial knowledge representation and reasoning often become an essential means for solving spatial constraint problems as found in science and engineering.
Insufficient compatibility of cavitation resistance assessments based on laboratory tests conducted under different cavitation conditions is generally considered a major methodological difficulty whenever quantitative prediction of material performance under field conditions is attempted.
Pulsed neutron gamma density logging (NGD) is of great significance for radioprotection and density measurement in LWD, however, the current methods have difficulty in quantitative calculation and single factor analysis for the inelastic gamma field distribution.
The discrepancy of the Cu LSPR λmax between experiment and theory can be attributed to the difficulty in quantitative and ultratrace measurement.
This discrepancy highlights the difficulty in quantitative comparisons of behavioral testing results between different laboratories.
