Analysis of sparse vector data using tessellation based on root volume–optimal cycles
Scientific ReportsThis study proposes a novel approach to investigate sparse vector datasets. The key feature of our method is the tessellation of space using volume–optimal cycles, a useful tool in persistent homology.

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia
Advanced Science, EarlyView.Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

Wrong FIX detection of RTK-GNSS positioning using the 3D point cloud of surrounding environment
ROBOMECH JournalGlobal Navigation Satellite Systems is a positioning system that receives signals from satellites. RTK-GNSS positioning uses multiple satellites and base stations. In RTK-GNSS positioning, the accuracy of the positioning solution is determined by a Ratio-

Harmonic Persistent Homology [PDF]
, 2022 We introduce harmonic persistent homology spaces for filtrations of finite simplicial complexes. As a result we can associate concrete subspaces of cycles to each bar of the barcode of the filtration.

Advanced Science, EarlyView.Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

Modeling Collaborations with Persistent Homology
CoRR, 2014 In this paper we describe a model based on persistent homology that describes interactions between mathematicians in terms of collaborations. Some ideas from classical data analysis are used.

The stability of persistent homology of hypergraphs [PDF]
, 2023 Hypergraph is the most general model for complex networks involving group interactions. Taking the ideas of path homology from Alexander Grigor'yan, Yong Lin, Yuri Muranov and Shing-Tung Yau [18-22], Stephane Bressan, Jingyan Li and the authors of this ...

Advanced Science, EarlyView.PRRSV vaccine‐mediated protection is associated with clonally expanded cytotoxic CD8+ T cell subsets driven by viral structural proteins and supported by innate TLR4/TLR8 signaling and CD4+ T cell help, whereas non‐protective responses are characterized by dysfunctional exhausted‐like CD8+ T cells linked to poor viral control.

Improved understanding of aqueous solubility modeling through topological data analysis
Journal of Cheminformatics, 2018 Topological data analysis is a family of recent mathematical techniques seeking to understand the ‘shape’ of data, and has been used to understand the structure of the descriptor space produced from a standard chemical informatics software from the point

Subsampling Methods for Persistent Homology
CoRR, 2014 Persistent homology is a multiscale method for analyzing the shape of sets and functions from point cloud data arising from an unknown distribution supported on those sets. When the size of the sample is large, direct computation of the persistent homology is prohibitive due to the combinatorial nature of the existing algorithms.
