homologous

[hə′mäl·ə·gəs]
(biology)
Pertaining to a structural relation between parts of different organisms due to evolutionary development from the same or a corresponding part, such as the wing of a bird and the pectoral fin of a fish.
(geology)
Referring to strata, in separated areas, that are correlatable (contemporaneous) and are of the same general character or facies, or occupy analogous structural positions along the strike.
Pertaining to faults, in separated areas, that have the same relative position or structure.

With the help of the persistence diagram, one can identify the significant homological features, which are located far from the main diagonal and filter the noisy features, which can be found near the main diagonal.
H1-K02 and H1-M27 sequences are highly homological. These sequences partially overlap with H1-JN; their occurrence in HIV-1 genome was again found to be very high and is identified in more than 1700 various isolates in the NCBI database.
At times, as in the case of Mallarme or Roussel, the homological rubric lacks the force of intentionality but works as an enabling hermeneutic tool.
In this review article, however, we have defined the induction of antinuclear antibodies as an autoimmune response due to the homological similarity of nuclear antigens even in different species.
Owen himself explained homological resemblance on the basis of a theory of identity with a transcendental archetype that functioned both as a kind of Platonic form underlying creation and also as an immanent organizing law of animal development.
In general terms, these problems are associated with the diminishing relevance of the nation state (i.e., with regard to language and culture but not in the political sphere) as the only referent in the literary development of a homological space amid clear and stable frontiers, immersed in an apparently contradictory double process, with globalization (which fragments and dissolves sovereignty amid various agents) on one hand, and localization (emergence of substatal spaces such as global cities and new areas) on the other.
The homological problem, hence a problem of social measurement, inherent in this approach is the assumption that aggregate data based on administratively defined neighborhoods are an accurate and adequate representation of the "true" neighborhood (Coulton, 2005; Coulton et al., 2001, 2004; Sampson et al., 2002).
(23) As these moments suggest, earth and human emerge in the plays, under the force of homological thinking, as creations twinned in anatomy (veins, wombs, blood), affections (sorrow, revenge), and physical states (thirst, hunger, and distemperance).
They provide homological proofs for a number of them, modifying the original proofs that involve simplicial methods, so they use only lower dimensional homology modules that they can introduce in an ad hoc manner, thus avoiding simplicial theory altogether.
More recently, similar ideas have been re-proposed by Persistent Homology according to a homological approach (Edelsbrunner et al., 2002; Edelsbrunner and Harer, 2008).
To recall Ferruccio Rossi-Landi (1985, 1992) and his distinction between analogy, isomorphism and homology, the icon involves homological similarity which is structural and/or genetic.
Two triangles and ABC and [A.sub.1][B.sub.1][C.sub.1], where [A.sub.1] [member of] BC, [B.sub.1] [member of] AC, [C.sub.1] [member of] AB, are called inscribed ortho homological triangles if the perpendiculars in [A.sub.1], [B.sub.1], [C.sub.1] on BC, AC, AB respectively are concurrent.
