Mercury's Internal Structure [PDF]
, 2018 We describe the current state of knowledge about Mercury's interior structure. We review the available observational constraints, including mass, size, density, gravity field, spin state, composition, and tidal response.

The internal structure of metacommunities [PDF]
Oikos, 2020 Current analyses of metacommunity data largely focus on global attributes across the entire metacommunity, such as mean alpha, beta, and gamma diversity, as well as the partitioning of compositional variation into single estimates of contributions of space and environmental effects and, more recently, possible contributions of species interactions ...

On Internal Structure, Categorical Structure, and Representation [PDF]
Philosophy of Science, 2022 AbstractIf categorical equivalence is a good criterion of theoretical equivalence, then it would seem that if some class of mathematical structures is represented as a category, then any other class of structures categorically equivalent to it will have the same representational capacities.
