Massive Spanning Forests on the Complete Graph: Exact Distribution and Local Limit

open access: yesRandom Structures &Algorithms, Volume 68, Issue 2, March 2026.
ABSTRACT We provide new exact formulas for the distribution of massive spanning forests on the complete graph, which give also a new outlook on the celebrated special case of the uniform spanning tree. As a corollary we identify their local limit. This generalizes a well‐known theorem of Grimmett on the local limit of uniform spanning trees on the ...

Solving a Random Asymmetric TSP Exactly in Quasi‐Polynomial Time W.H.P.

open access: yesRandom Structures &Algorithms, Volume 68, Issue 2, March 2026.
ABSTRACT Let the costs C(i,j)$$ C\left(i,j\right) $$ for an instance of the Asymmetric Traveling Salesperson Problem (ATSP) be independent copies of a nonnegative random variable C$$ C $$ from a class of distributions that include the uniform [0,1]$$ \left[0,1\right] $$ distribution and the exponential mean 1 distribution with mean 1.

Comparison of Methods for Sensitivity Analysis of Heterogeneous Treatment Effects in Observational Studies and Application to Alzheimer's Disease and Cognitive Decline

open access: yesStatistics in Medicine, Volume 45, Issue 6-7, March 2026.
ABSTRACT In Alzheimer's disease (AD) research, many observational studies have shown that the effect of sleeping quality, a modifiable risk factor, on cognitive decline is heterogeneous, where some adults experience faster rates of cognitive decline compared to others.

A conceptual framework for revealing rare bacterial species in the gut microbiome through guided data transformation: Beyond enterotypes

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 821-836, March 2026.
Abstract The gut microbiota is increasingly recognized as a rich source of biological data that offers critical information on host health, including information on pathological conditions such as cancer, diabetes and other metabolic disorders. Inferring host health from gut bacterial composition using statistical analytical methods remains a challenge.
