The phrase "active reference" is correct and usable in written English.
It can be used in contexts where you are discussing a source or citation that is currently being utilized or engaged with in a text or discussion.
Example: "In this research paper, I will provide an active reference to the latest studies on climate change."
Alternatives: "current citation" or "live reference".
Co-located active (reference) and passive (PAAS) samplers were used for pollen; passive monitoring for CO2 (Telaire 7001) and active sampling for PM were conducted.
As far as Ku band system is concerned, the sigma naught absolute calibration of the Envisat altimeter (RA-2) has been performed using an active reference target provided by a transponder.
active: positive peptides except for active reference.
Both systems are active reference, and product studio quality sound in a compact package.
active reference: positive peptides which are the basis of similarity search with Tanimoto coefficient.
Thus, the set of active reference classes and/or system classes does not change during any segment.
Otherwise we separated active references from inactive references and created two profiles.
If the cluster was composed of all active references or all inactive references, we created a single profile to represent the structure feature of that set of compounds.
It should be mentioned that the maximal compression ratio reached 160, even if we limited the number of inactive compounds in the reference set and controlled the ratio of active references and inactive references to above 1 5.
In addition, the major difference between ISS and ISC is that when querying with the ISS search approach, only active references participate in the step of iterative database screening, while ISC can be considered as the combination of ISS search with all active references and ISS search with all inactive references.
If ISS has high specificity in retrieving active compounds, the reverse version of ISS by replacing active references in the neighbor list with inactive references should also retain the ability to identify inactive compounds.
