Projective Dirac Operators, Twisted K-Theory, and Local Index Formula [PDF]

, 2011
We construct a canonical noncommutative spectral triple for every oriented closed Riemannian manifold, which represents the fundamental class in the twisted K-homology of the manifold.

Homology modeling of the CheW coupling protein of the chemotaxis signaling complex. [PDF]

PLoS ONE, 2013
Homology models of the E. coli and T. maritima chemotaxis protein CheW were constructed to assess the quality of structural predictions and their applicability in chemotaxis research: i) a model of E. coli CheW was constructed using the T.

A Topological Data Analysis approach for retrieving Local Climate Zones patterns in satellite data

Environmental Challenges, 2021
In the context of geospatial studies, meaningful information may be hidden in the aspects of form and connectivity inscribed in the measurements. Therefore, here is proposed the use of H0 Persistent Homology (PH), a Topological Data Analysis tool to ...

The cobordism group of homology cylinders [PDF]

, 2010
Garoufalidis and Levine introduced the homology cobordism group of homology cylinders over a surface. This group can be regarded as an enlargement of the mapping class group.

Molecular identification of isolates from local microorganisms as potential biofertilizer

Sains Tanah: Journal of Soil Science and Agroclimatology, 2021
Local microorganisms (MOL) are liquid fertilizers commonly used by farmers to help increase crop production. Beneficial microbes in MOL need to characterize their interactions and ability to produce growth drive compounds. The purpose of this research is

Phytochemical analysis and anticancer effect of Camellia oleifera bud ethanol extract in non-small cell lung cancer A549 cells

Frontiers in Pharmacology
Camellia oleifera is a medicine food homology plant widely cultivated in the Yangtze River Basin and southern China due to its camellia oil. Camellia oleifera bud and fruit exist simultaneously, and its bud is largely discarded as waste.

Bredon homology and equivariant K-homology of SL(3,Z)

, 2008
We obtain the equivariant K-homology of the classifying space underline{E}SL(3,Z) from the computation of its Bredon homology with respect to finite subgroups and coefficients in the representation ring.
