STopover captures spatial colocalization and interaction in the tumor microenvironment using topological analysis in spatial transcriptomics data

STopover analyzes spatial transcriptomics data to identify cell-cell interactions and colocalization patterns in the tumor microenvironment.

Time-varying hierarchical core voxels disclosed by k-core percolation on dynamic inter-voxel connectivity resting-state fMRI

The paper uses k-core percolation on dynamic resting-state fMRI to reveal time-varying hierarchical brain connectivity and its relation to mental states.

Characteristic core voxels in normal individuals revealed by hyperbolic disc embedding and k-core percolation on resting state fMRI

The paper identifies characteristic core structures in resting-state fMRI data using hyperbolic disc embedding and k-core percolation, revealing individual differences in brain connectivity patterns.

Exact Topological Inference For Paired Brain Networks Via Persistent Homology

The paper introduces a framework for analyzing paired brain networks using persistent homology and sparse learning, demonstrating its application to twin fMRI data to assess heritability significance.
