  4. Functional selectivity (or “agonist trafficking”, “biased agonism”, “differential engagement” and “protean agonism”) is the ligand-dependent selectivity for certain signal transduction pathways in one and the same receptor. ...
  5. (Selectivity (electronic)) Selectivity is a measure of the performance of a radio receiver to respond only to the radio signal it is tuned to (such as a radio station) and reject other signals nearby in frequency, such as another broadcast on an adjacent channel.
  6. (Selectivity (pharmacology)) Binding selectivity refers to the differing affinities with which different ligands bind to a substrate forming a complex. ...
  7. Of or pertaining to the process of selection; Choosy, fussy or discriminating when selecting; Having the authority or capability to make a selection
  8. (selectivity) The tendency of an ion exchanger to "prefer" (have more attraction for) certain kinds of ions over others, as if the resin were ranking the types of ions in order to be removed; most preferred ion, second most preferred, etc..
  9. (Selectivity (Weight)) The ability of a medium to reach a specific target group in greater proportion than other media.
  10. (Selectivity) The ability of a type of gear to target and catch a certain size or species of fish.
  11. (Selectivity) The ability of a receiver to reject interfering signals close to the desired carrier frequency.
  12. (Selectivity) used to describe the variability in rate of movement of different ions thru the same ion channel.   The "height" of the energy barrier of an ion channel's selectivity filter will help determine ion it let thru. ...

  21. (Selectivity) The application of safeguards in such a way as to restrict imports from a particular country or group of countries, in contrast with non-discriminatory actions taken according to the most-favored-nation principle. ...
  22. (Selectivity) The difference in attraction of one ion over another by an ion exchange resin
  23. (Selectivity) The effectiveness of a solvent extraction is dependent on the solution being separated and the concentration of solutes present in the solutions. The ratio of ratios, the separation factor, or selectivity, β, is analogous to the relative volatility of distillation. ...
  24. (Selectivity) for columns, the relative affinities of a pair of analytes for a stationary phase under a given set of chromatographic conditions. For detectors, the types of compounds which will cause a detector response.
  25. (Selectivity) is the filtering of incoming information from the outside world, recognizing and interpreting the meaning and consequences of incoming signals.
