Finding interactions between variables in large and high-dimensional datasets is often a serious computational challenge. Most approaches build up interaction sets incrementally, adding variables in a greedy fashion. The drawback is that potentially informative high-order interactions may be overlooked.

Automorphisms of Random Trees.
We study the size of the automorphism group of two different types of random trees: Galton-Watson trees and Pólya trees. In both cases, we prove that it asymptotically follows a log-normal distribution. While the proof for Galton-Watson trees mainly relies on probabilistic arguments and a general result on additive tree functionals, generating ...

The human gut microbiome across the life course
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Empirical distribution of random tree scores.
Ten thousand random matrices were created from the matrix used to create the sample dendrogram in Figure 1 by randomly rearranging the peptide intensity values within each sample. For each score that was given to at least one random tree, the frequency

The probability space consisting of all graphs on a set of \(n\) vertices where each edge occurs with probability \(p\), independently of all other edges, is denoted by \(G(n,p)\). Theorem: For each \(\epsilon>0\) almost every graph \(G\in G(n,p)\) is such if \((1+\epsilon)\log n/\log ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Spectral asymptotics for stable trees [PDF]
We calculate the mean and almost-sure leading order behaviour of the high frequency asymptotics of the eigenvalue counting function associated with the natural Dirichlet form on alpha-stable trees, which lead in turn to short-time heat kernel asymptotics

Self-similarity and spectral asymptotics for the continuum random tree
We use the random self-similarity of the continuum random tree to show that it is homeomorphic to a post-critically finite self-similar fractal equipped with a random self-similar metric.

A new generation tree for permutations, preserving the number of fixed points [PDF]
We describe a new uniform generation tree for permutations with the specific property that, for most permutations, all of their descendants in the generation tree have the same number of fixed points.
