The authors found hundreds of different immune variants, but these so called 'alleles' appear to be clustered in a smaller number of functional groups or 'supertypes'.
A large number of epitopes were predicted against 10 selected supertypes at various binding scores.
This book introduces the term "linguistic supertypes," and the reader would like very much to see a careful discussion of this new concept from linguistic typology inside "a cognitive-semiotic theory of human communication." From the cognitive perspective, Durst-Anderson takes language to be a perceptual activity of the brain/mind, while from the semiotic perspective, the author studies the role of language in the processes of sign and communication.
An inheritance relationship (i.e., a subtype and supertype relationship) is presented as a thick line.
* the extensions of subtypes are subsets of the extensions of their supertypes, so that the instances of a subtype can occur wherever instances of its supertypes are expected (principle of substitutability).
That is, a supertype was modeled as a variant record with a separate branch for each subtype.
In theory, cross-reaction due to the HLA-B7 antigen might be recognized by simultaneous HLA-Bw4 typing: The B27 antigen belongs to the Bw4 superfamily of antigens, whereas the B7 antigen is part of the Bw6 supertype, and therefore an apparent positive reaction of any anti-B27 antiserum can be reliably classified as false positive when the cells are Bw4 negative.
If ML had subtyping and a supertype T of all types, a correct equation would be D(T); T = T.
Powerful object models adopt multiple inheritance, allowing a type (or class) definition to inherit from more than one supertype. Unfortunately, in applying this powerful modeling mechanism, inheritance conflicts may be generated, which arise when the same property or operation is defined in more than one supertype.
Our HLA dataset contains six A * 68 alleles, out of which two belong to different supertypes: A * 68:01 to the A3 supertype and A * 68:02 to the A2 supertype.
Secondly, the arguments [bar]U must be chosen in such a way that any other choice of arguments [bar]V satisfying the previous condition will yield a less informative result type, i.e., a supertype of [[bar]U/[bar]X]R.
There would be a strong flavor of object-orientation, with "supertype classification schemes" to "formalize" the components.
