Topological Metric Detects Hidden Order in Disordered Media
Physical Review Letters
Recent advances in microscopy techniques make it possible to study the growth, dynamics, and response of complex biophysical systems at single-cell resolution, from bacterial communities to tissues and organoids. In contrast to ordered crystals, it is less obvious how one can reliably distinguish two amorphous yet structurally different cellular materials. Here, we introduce a topological earth mover's (TEM) distance between disordered structures that compares local graph neighborhoods of thedoi:10.1103/physrevlett.126.048101 pmid:33576647 fatcat:47vvajuntnhwpgiyzgpxamjhd4
