Cladistics, 2011
AbstractHomology in cladistics is reviewed. The definition of important terms is explicated in historical context. Homology is not synonymous with synapomorphy: it includes symplesiomorphy, and Hennig clearly included both plesiomorphy and synapomorphy as types of homology.

When is homology not homology?
Current Opinion in Genetics & Development, 1998Although genes have specific phenotypic consequences in a given species, this functional relationship can clearly change during the course of evolution. Many cases of evolutionary dissociations between homologous genes and homologous morphological features are now known.

FLOER HOMOLOGY AND INVARIANTS OF HOMOLOGY COBORDISM
International Journal of Mathematics, 1998By using surgery techniques, we compute Floer homology for certain classes of integral homology 3-spheres homology cobordant to zero. We prove that Floer homology is two-periodic for all these manifolds. Based on this fact, we introduce a new integer valued invariant of integral homology 3-spheres.

From Leibniz Homology to Cyclic Homology
K-Theory, 2002Given an algebra \(A\), the author constructs a natural homomorphism \(HL_{\ast+1}(A)\to HH_\ast(A)\) from Leibniz to Hochschild homology. If \(f: A\to B\) is a homorphism of algebras, the relative Leibniz homology \(HL_\ast(gl(f))\) is defined and a natural homomorphism \(HL_{\ast+1}(gl(f))\to HC_\ast(F)\) to relative cyclic homology is studied. Thus,

Cladistics, 2012
AbstractA recent review of the homology concept in cladistics is critiqued in light of the historical literature. Homology as a notion relevant to the recognition of clades remains equivalent to synapomorphy. Some symplesiomorphies are “homologies” inasmuch as they represent synapomorphies of more inclusive taxa; others are complementary character ...

Canadian Journal of Mathematics, 1978
There have been few published results concerning the relationship between the homology groups of branched and unbranched covering spaces of knots, despite the fact that these invariants are such powerful invariants for distinguishing knot types and have long been recognised as such [8]. It is well

Fertility and Sterility, 1978
Between July 1, 1969, and October 31, 1977, 619 patients were evaluated for infertility. Homologous insemination (AIH) was employed in 53 patients, many of whom had other contributory causes of infertility. There have been 14 single pregnancies in 11 women, including 4 spontaneous abortions, 1 ectopic pregnancy, 8 term deliveries, and 1 pregnancy in ...
