Definitions for "Selectivity"
The ability of a receiver to select the desired signal and reject unwanted signals.
A detector's ability to detect police radar while ignoring the presence of such devices as automatic garage door openers and microwaves, which may operate on closely neighboring frequencies. A good radar detector offers high selectivity as well as being highly sensitive.
The ability to focus on sounds. A dozen separate sounds reach the ears at any given moment and under normal circumstances we have the ability to focus on any one of them. A hearing impairment can cause a loss of selectivity.
Keywords:  kappa, opioid, lignin, affinity, delta
the relationship between the affinity of a compound for a particular receptor and its affinity for other types of opioid receptor. For instance, a compound that will bind with high affinity to the mu-receptors, but with very low affinity to kappa and delta receptors, is said to possess high selectivity for mu.
Relative extent to which active cooking chemicals attack the lignin and preserve the carbohydrates, i.e. better selectivity is synonymous to higher yield and/or better viscosity at a given kappa number.
Automated method of designating imported merchandise for examination by a CBP inspector or commodity specialist.
Ease of accessibility of merchandise. The number of "facings"or immediately accessible storage slots. Selectivity is sometimes expressed as the percentage of the total storage slots which are immediately accessible.
Selectivity refers to application of safeguards measures in a discriminatory manner, against a particular country whose exports have risen and contributed particularly to the "injury."
A system for the adjustment of quotas within groups of coffee in response to movements in the relevant group indicator prices. Adjustments are applicable only to exporting Members in the group affected.
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. Often, the term selectivity is not properly defined and can refer to either of the two processes of permeability or conduction. The distinction should always be made.
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.
The characteristic of herbicides whereby certain plant species are killed while others are injured little if at all.
Refers to the range of organisms or life stages of organisms affected by a pesticide; a selective pesticide is toxic to a narrow range of pests species or life stages.
the difference in removal rate between two material during an etching or CMP process.
separation factor or relative retention.
Measures the relative vulnerability of different age (size) classes to the fishing gears(s).
Viewed by some as a measure of college quality, selectivity is based on the number of applicants accepted out of the number that apply. Selectivity ratings are developed by college rating services from statistics the colleges supply. Selectivity ratings should be considered in the context of yield - the number of admitted students who choose to enroll.
