Catalog of species found in the deep red coral gardens off Portugal (Atlantic) made with video snapshots. Short descriptions are provided when appropriate.
We start with a simple introduction to topological data analysis where the most popular tool is called a persistence diagram. Briefly, a persistence diagram is a multiset of points in the plane descri
We use topological methods to investigate the small-scale variation and local spatial characteristics of the interstellar medium (ISM) in three regions of the southern sky. We demonstrate that there a
