Connectivity reveals homology between the visual systems of the human and macaque brains

open access: yesFrontiers in Neuroscience, 2023
The visual systems of humans and nonhuman primates share many similarities in both anatomical and functional organization. Understanding the homology and differences between the two systems can provide important insights into the neural basis of visual ...

The Hodge conjecture: The complications of understanding the shape of geometric spaces

open access: yesMètode Science Studies Journal: Annual Review, 2018
The Hodge conjecture is one of the seven millennium problems, and is framed within differential geometry and algebraic geometry. It was proposed by William Hodge in 1950 and is currently a stimulus for the development of several theories based on ...

Evolution, Homology, and Development of Tetrapod Limb Muscles

open access: yesDiversity, 2021
Since the early 1900s, researchers have attempted to unravel the origin and evolution of tetrapod limb muscles using a combination of comparative anatomy, phylogeny, and development.

Symmetric Homology is Representation Homology

open access: yes, 2022
Symmetric homology is a natural generalization of cyclic homology, in which symmetric groups play the role of cyclic groups. In the case of associative algebras, the symmetric homology theory was introduced by Z. Fiedorowicz \cite{F} and was further developed in the work of S. Ault \cite{Au1, Au2}. In this paper, we show that, for algebras defined over

Nitrogenase and homologs [PDF]

open access: yesJBIC Journal of Biological Inorganic Chemistry, 2014
Nitrogenase catalyzes biological nitrogen fixation, a key step in the global nitrogen cycle. Three homologous nitrogenases have been identified to date, along with several structural and/or functional homologs of this enzyme that are involved in nitrogenase assembly, bacteriochlorophyll biosynthesis and methanogenic process, respectively.

Persistent homology for 3D reconstruction evaluation [PDF]

open access: yes, 2012
Space or voxel carving is a non-invasive technique that is used to produce a 3D volume and can be used in particular for the reconstruction of a 3D human model from images captured from a set of cameras placed around the subject.

Homology stratifications and intersection homology [PDF]

open access: yesGeometry & Topology Monographs, 1999
A homology stratification is a filtered space with local homology groups constant on strata. Despite being used by Goresky and MacPherson [Intersection homology theory: II, Inventiones Mathematicae, 71 (1983) 77-129] in their proof of topological invariance of intersection homology, homology stratifications do not appear to have been studied in any ...
