superdominant

1. (law) Having an overwhelming proportion of market share, so as to be almost a monopoly.Examples: "I would like to come back to the idea of making a distinction between so-called 'superdominant' companies and 'just dominant' companies."; "According to O'Donoghue & Padilla (2006) 168–69, the concept of superdominance is problematic, given that there is no objective economic test that makes it possible to define when a company is superdominant and its behaviour should be subjected to greater scrutiny."; "Simply put, if the entity that is in superdominant position is allowed to justify its rules or conduct that have restrictive effect on the market, then the claimed benefits to the public interest should be proven genuine and not merely hypothetical."

2. (biology) Holding a position of absolute dominance.Examples: "Although the level of aggression was greatly reduced after the first day, the superdominant hierarchy persisted, although not always with the same superdominant individual."; "In the competition-dependent alternatives of a social insect colony or a lek, the frequency of dominant individuals need only be one to make subordinate alternatives more advantageous, and the frequency of dominant behavior may only vary between one (when the superdominant position of queen or harem chief is filled) and zero (when the position becomes vacant)."; "Studies of groups of 5 previously isolated juvenile crayfish grouped together in a small 18cm x 18cm square aquarium indicate that they form tyrannies, in which one animal is superdominant to the others (Issa et al., 1999)."

3. (genetics) Controlling or enhancing the expression of another pair of genes or chromosomes.Examples: "If the collection of ten polymorphic loci contains both dominant and superdominant loci, the graph comprises the same line segment for any ratio of dominant and superdominant loci."; "Suppose a “superdominant” Y chromosome arose that could not be feminized by X*."

4. (anatomy, of an artery) Sufficiently large so as to control the blood flow to an area.Examples: "The RCA is dominant, but not superdominant, because the ST elevation in V 5-6 is a little smaller than 2 mm."; "In this rare anomaly, a large “superdominant” right coronary artery crosses the crux of the heart, ascending the atrioventricular groove to perfuse the posterior and lateral wall of the heart."

5. (forestry) Rising above the general level of the overstory.Examples: "The managed old-growth alternative would actively recruit an acceptable number of large snags over time by allowing superdominant leave trees to mature and convert to large snags."; "A few large dominant or superdominant trees should be left as potential nest trees."; "Trees should not be included in a superdominant stratum unless they are considerably larger and clearly of an earlier generation than the trees of the main overstory."

6. (decision theory) Comprising the winning strategy in all cases.Examples: "In decision-theoretical tenns, therefore, to believe in God is superdominant over disbelieving."
