Singular expressions name and signify individuals, albeit general terms name and signify common natures.
Proper names and individual expressions name individuals (i.e., object tokens), but general terms name common natures (i.e., object types), which are the metaphysical constituents of the set of individuals instantiating them.
Alternatively, one might endorse the claim that the reference of all indexical expressions — names and other indexicals alike — is fixed by the content of an accompanying description.
Let the indefinite proposition '$x$ is a black ball in this urn' be such that the variable '$x$' may take as value any expression naming a ball in the urn: the variable is then said to range over the individual balls, and different expressions naming the same ball to have the same value.
We then isolated two monoclonal parkin-expressing lines from the polyclonal pool with differential parkin expression, named clones M1 and M2.
(Exercise) That is, fαˆ is an expression naming the function which takes a function φ to a proposition which asserts f of the class of φs.
In this case, the denotation of GreatGeneral, and the range of the variable 'φ', is of order 1, and no other expression names or ranges over an entity of higher order.
COI12 and HSP82 coding regions that were optimized for E. coli expression, named COI12Ec and HSP82Ec, respectively, were synthesized (GenScript).
Perhaps more importantly, the accompanying paper shows that transient and infrequent bursts of Zscan4 expression (named 'Z4 events') are accompanied by the rapid derepression of heterochromatin, particularly in the pericentromeric region, and the clustering of pericentromeric heterochromatin around the nucleolus.
Although common site names are now being selected from a list of pre-defined expressions, the name is stored as free text and can be modified by the curators as they see fit.
The head of the expression is a tuple of three expressions: the name of the polypeptide, the gene(s) producing this polypeptide and the left-end position(s) of the gene(s) on the genome.
