Associations Between 40‐Year Trajectories of BMI and Proteomic and Epigenetic Aging Clocks: Deciphering Nonlinearity and Interactions

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
In twins followed up over 40 years across adulthood, we examined associations between long‐term body mass index trajectories and downstream acceleration in proteomic and epigenetic aging. We further examined whether these associations showed statistical evidence for nonlinear patterns.

A complex network perspective on brain disease

open access: yesBiological Reviews, Volume 101, Issue 1, Page 364-399, February 2026.
ABSTRACT If brain anatomy and dynamics have a complex network structure as it has become standard to posit, it is reasonable to assume that such a structure should play a key role not only in brain function but also in brain dysfunction. However, exactly how network structure is implicated in brain damage and whether at least some pathologies can be ...

Robust estimation of a Markov chain transition matrix from multiple sample paths

open access: yesStatistica Neerlandica, Volume 80, Issue 1, February 2026.
Markov chains are fundamental models for stochastic dynamics, with applications in a wide range of areas such as population dynamics, queueing systems, reinforcement learning, and Monte Carlo methods. Estimating the transition matrix and stationary distribution from observed sample paths is a core statistical challenge, particularly when multiple ...
