Mathematical conceptualism [PDF]
This is an explanation and defense of "mathematical conceptualism" for a general mathematical and philosophical audience. I make a case that it is cogent, rigorous, attractive, and better suited to ordinary mathematical practice than all other foundational stances.

Repairing gaps in ecological time series
Abstract Missing values are ubiquitous in ecological time series. Methods like linear interpolation, k‐nearest neighbour (kNN) imputation or regression‐based imputation are commonly used to repair these gaps, but may be unsuitable when the data are infrequently sampled or have nonlinear dynamics.

Proteolysis‐Based Biomarker Repertoire of the Neurofilament Proteome
Protein degradation underlies essential biological processes, and its dysfunction can contribute to disease. By systematically charting the neurofilament degradome, this study offers a conceptual framework and methodological blueprint for mapping a complete protein degradome atlas.

Lattice Multiverse Models [PDF]
Will the cosmological multiverse, when described mathematically, have easily stated properties that are impossible to prove or disprove using mathematical physics? We explore this question by constructing lattice multiverses which exhibit such behavior even though they are much simpler mathematically than any likely cosmological multiverse.

The combinatorics of tastes and humours in classical Indian medicine and mathematics [PDF]
This paper explores some combinatoric problems which are treated in the Sanskrit literature of both ayurveda (medicine) and of jyothsastra (mathematics)

Universality for transversal Hamilton cycles
Abstract Let G={G1,…,Gm}$\mathbf {G}=\lbrace G_1, \ldots, G_m\rbrace$ be a graph collection on a common vertex set V$V$ of size n$n$ such that δ(Gi)⩾(1+o(1))n/2$\delta (G_i) \geqslant (1+o(1))n/2$ for every i∈[m]$i \in [m]$. We show that G$\mathbf {G}$ contains every Hamilton cycle pattern.

On minimal presentations of numerical monoids
Abstract We consider the classical problem of determining the largest possible cardinality of a minimal presentation of a numerical monoid with given embedding dimension and multiplicity. Very few values of this cardinality are known. In addressing this problem, we apply tools from Hilbert functions and free resolutions of artinian standard graded ...

The Shi variety corresponding to an affine Weyl group
Abstract Let W$W$ be an irreducible Weyl group and Wa$W_a$ its affine Weyl group. In this article we show that there exists a bijection between Wa$W_a$ and the integral points of an affine variety, denoted X̂Wa$\widehat{X}_{W_a}$, which we call the Shi variety of Wa$W_a$.

Abstract We provide partial solutions to two problems posed by Shehtman concerning the modal logic of the Čech–Stone compactification of an ordinal space. We use the Continuum Hypothesis to give a finite axiomatization of the modal logic of β(ω2)$\beta (\omega ^2)$, thus resolving Shehtman's first problem for n=2$n=2$. We also characterize modal logics
