Non-negative matrix factorization is a useful tool for reducing the dimension of large datasets. This work considers simultaneous non-negative matrix factorization of multiple sources of data. In particular, we perform the first study that involves m

One tool to analyze the qualitative behavior of a periodic orbit of a vector field in $\mathbb{R}^n$ is to consider the Poincaré return map to an $(n-1)$-dimensional section. The image under the Poincaré map of a point on this section that lies nea

When one considers a Poincarreturn map on a general unbounded (n - 1)-dimensional section for a vector field in R-n there are typically points where the flow is tangent to the section. The only notable exception is when the system is (equivalent to)

Background: Healthcare workers (HCW) are a crucial part of the workforce but are also at potentially at increased risk of infection from SARS-CoV-2. Emerging evidence has suggested specific groups of HCW are at further increased risk particularly tho
