The phrase "a more complex linkage" is correct and usable in written English.
It can be used when discussing relationships or connections that involve multiple factors or elements, indicating that the linkage is not straightforward.
Example: "The study revealed a more complex linkage between environmental factors and health outcomes than previously understood."
Alternatives: "a more intricate connection" or "a more complicated relationship".
Key to their vision is the concept of 'Intelligent Openness' (Table 1), a standard that Biodiversity Informatics must attain before attempting more complex linkage of services.
The lack of exposure data is an impediment to more complex linkages.
The analytical framework presents groups of analyses to facilitate a progression from descriptive analyses to more complex linkages; this builds the foundation for etiologic research using epidemiologic studies.
As more complex linkages and analyses are conducted, greater statistical expertise will be needed in this initiative.
In the descriptive analyses, the lack of exposure data may be acceptable, but studies of more complex linkages will require more and better data.
Once linkage allows the evolution of a more complex metabolism other linkage mechanism could also be explored.
Examples may include the annotation of the Binding event through the linkage of a substrate term (e.g., malate) with a protein term (e.g., Mdh) or the annotation of a more complex Cause event through the linkage of the stress term (e.g., chromate shock) with the Up-regulation and Down-regulation events, which are, in-turn, linked with the proper gene-related terms (e.g., SO_2426 and omcB).
However, the number of transgressive genes for which we were able to identify genomic linkage was lower in aging worms, suggesting that a more complex polygenic regulation affected our ability to detect linkages at these ages.
However, ILGA uses a more complex simulation environment, captures the emergence of affordance representations in AIP, and addresses the linkage between reaching and grasping in ways that TRoPICALS does not.
At higher doses, the polymer becomes a more complex matrix due to the occurrence of inter- and intra-molecular hydrogen bonding as well as radical linkage initiated by gamma irradiation between the cyclic structure constituents of the polymer molecules [56].
