Graph Attention Networks

Petar Veličković, +5 more
TL;DR: Graph Attention Networks (GATs) as mentioned in this paper leverage masked self-attentional layers to address the shortcomings of prior methods based on graph convolutions or their approximations.
Journal ArticleDOI

Hematopoietic Stem Cells Reversibly Switch from Dormancy to Self-Renewal during Homeostasis and Repair

Anne Wilson, +12 more
- 10 Jul 2009 - 
TL;DR: Flow cytometry with label-retaining assays are combined to identify a population of dormant mouse HSCs (d-HSCs) within the lin(-)Sca1+cKit+CD150+CD48(-)CD34(-) population, indicating that d-H SCs harbor the vast majority of multilineage long-term self-renewal activity.
