Beyond Substitution—An Antipositionalist's Guide to Subtraction—

open access: yesPhilosophy and Phenomenological Research, EarlyView.
ABSTRACT Existing accounts of relations do not properly account for variably polyadic relations: they fail to capture the relationship between completions of the same relation by different numbers of relata. This paper develops a fully general account of such relations by adding an operation of subtraction to the antipositionalist theory of relations ...

The Interrelated Mathematics Learner Identities and Mathematics Teacher Identities of Preservice Elementary Teachers

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT Despite consistent efforts for change in mathematics education aligned with ambitious and equitable teaching practices, many preservice teachers continue to enroll in teacher‐preparation programs having learned mathematics in traditional, teacher‐centered ways. If mathematics teacher educators are to support preservice teachers in breaking the

Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

open access: yesExperimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.

On computing local monodromy and the numerical local irreducible decomposition

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Similarly to the global case, the local structure of a holomorphic subvariety at a given point is described by its local irreducible decomposition. Geometrically, the key requirement for obtaining a local irreducible decomposition is to compute the local monodromy action of a generic linear projection at the given point, which is always well ...

On the additive image of zeroth persistent homology

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...
