Geometriae Dedicata, 2022 Let $Γ_g$ be the fundamental group of a closed connected orientable surface of genus $g\geq2$. We introduce a combinatorial structure of "core surfaces", that represent subgroups of $Γ_g$. These structures are (usually) 2-dimensional complexes, made up of vertices, labeled oriented edges, and $4g$-gons.

International Astronomical Union Colloquium, 2000 Abstract We carried out the Gaussian fitting to the profile of PSR B1237+25 and found that six components rather than five are necessary to make a good fit. In the central part, we found that the core emission is not filled pencil beam but is a small hollow cone. This implies that the impact angle could be β < 0.5°.

Multivariate Hierarchical Frameworks for Modelling Delayed Reporting in Count Data [PDF]
, 2019 In many fields and applications count data can be subject to delayed reporting. This is where the total count, such as the number of disease cases contracted in a given week, may not be immediately available, instead arriving in parts over time.
