The phrase "a more complex sample" is correct and usable in written English.
It can be used when discussing a sample that has multiple layers or intricacies, often in contexts like research, analysis, or data collection.
Example: "In our study, we decided to analyze a more complex sample to better understand the underlying patterns."
Alternatives: "a more intricate example" or "a more detailed specimen".
Fraction S5 is a more complex sample, containing all small molecular weight biomolecules, including peptides, mono- and oligosaccharides, primary metabolites, amino acids, cofactors and many others.
The CE-MS interface was subsequently used to analyse a more complex sample of pharmaceutically relevant human proteins including insulin, tissue factor and α-synuclein.
To analyze the extent of coverage of both a simple and a more complex sample, we sequenced a control viral sample, the canonical NL4-3 strasn, as well as a clinical sample consisting of a heterogeneous HIV population.
A more complex sample consisting of a mixture of 24 known strains of West Nile Virus sequenced by 454 was also analyzed.
These data suggest that, with prior knowledge of the error profile, rare variants in a more complex sample can be identified with high accuracy.
In a more complex sample of 1.7% of each Bt176, RRS and MON1445, the GMO elements FMV P35S and bar could still be detected, while the GMO element CaMV P35S, often used as a screening element, was still detectable in the lowest GMO mixture tested (1%).
A more complex sampling and recruitment strategy was required for the city of Brisbane.
At 12 and 48 months, a more complex sampling scheme was used: all low birthweight children plus 20% of the remainder, including those visited at 3 months, were visited at home (1460 and 1450 children, respectively).
19 We included only two arm parallel group superiority randomised controlled trials with a single primary outcome, so we did not assess more complex sample size calculations.
The high brilliance at the European Spallation Source (ESS) will allow for performing experiments with much smaller samples than at present neutron facilities and in much more complex sample environments.
Thus, the proposed method solves the problem of dimension change from sample space mapping to feature space, and it reduces the restrictions on the sample sets, which is adaptable to more complex sample sets.
