Tissue phase transitions in development: more than just mechanics
Summary: Tissue material phase transitions are classically thought to regulate tissue deformability. This Review emphasises their unexpected roles in directly influencing growth and patterning signall...

An assortment of problems in permutation patterns: unimodality, equivalence, derangements, and sorting
We collect open problems in permutation patterns on four themes: rank-unimodality in the permutation pattern poset, Wilf-equivalence and shape-Wilf-equivalence, the enumeration of derangements in perm...

Intersections of special cycles on Shimura curves and Siegel Maass forms
We show that the generating series of the number of pairs of geodesics on a compact Shimura curve with given discriminants and intersection angle are coefficients of a non-holomorphic Siegel modular f...

An Explicit Skew-Hadamard Matrix of Order 1252 via Cyclotomic Unions
We construct a skew-Hadamard matrix of order 1252 = 2(5^4 + 1) using a bordered skew-Hadamard difference family over GF(5^4), with blocks given as unions of cyclotomic classes of order N = 16. This or...

Counting Colored Trees

New preprint!
Why do people disagree about what looks beautiful, even when viewing the same stimulus?
We show that shared aesthetic experience is linked to shared gaze during naturalistic viewing: www.biorxiv.org/content/10.6...
