Homological scaffold via minimal homology bases [PDF]

Scientific Reports, 2021
AbstractThe homological scaffold leverages persistent homology to construct a topologically sound summary of a weighted network. However, its crucial dependency on the choice of representative cycles hinders the ability to trace back global features onto individual network components, unless one provides a principled way to make such a choice.

Null-homologous exotic surfaces in 4-manifolds [PDF]

, 2019
In this paper we exhibit infinite families of embedded tori in 4-manifolds that are topologically isotopic but smoothly distinct. The interesting thing about these tori is that they are topologically trivial in the sense that each bounds a topologically ...

Differences of inter-tract correlations between neonates and children around puberty: A study based on microstructural measurements with DTI

Frontiers in Human Neuroscience, 2013
The human brain development is a complicated yet well-organized process. Metrics derived from diffusion tensor imaging (DTI), including fractional anisotropy (FA), radial (RD), axial (AxD) and mean diffusivity (MD), have been used to noninvasively access

A Hierarchical Approach to Protein Molecular Evolution [PDF]

, 1999
Biological diversity has evolved despite the essentially infinite complexity of protein sequence space. We present a hierarchical approach to the efficient searching of this space and quantify the evolutionary potential of our approach with Monte Carlo ...

Genes and homology [PDF]

Current Biology, 2004
What is the origin of the term ‘homology’? Richard Owen (1804–1892) defined homology as “the same organ under every variety of form and function”. Owen conceived of homologous structures as those that, while differing in detail, were derived from the same body plan, or ‘archetype’.

Protection against Different Genotypes of Newcastle Disease Viruses (NDV) Afforded by an Adenovirus-Vectored Fusion Protein and Live NDV Vaccines in Chickens

Vaccines, 2021
The efficacy of an adenovirus-vectored Newcastle disease virus (NDV) vaccine expressing the fusion (F) NDV protein (adeno-F) was evaluated against challenges with virulent heterologous and homologous NDV strains to the F protein.
