Mediation Analysis With Bayesian Nonlinear Joint Models: Evaluation of the Treatment Causal Pathways Between Tumor Growth Kinetics and Overall Survival

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.
ABSTRACT Understanding the mechanisms through which anti‐cancer treatments influence survival is central to improving drug development and evaluation. In this work, we develop a Bayesian joint modeling framework for mediation analysis to quantify the extent to which tumor size dynamics mediate the effect of treatment on overall survival (OS). Our model

Empirical Comparison of Win Ratio and Joint Frailty Models for Recurrent Event Endpoints With Applications in Oncology and Cardiology

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.
ABSTRACT Composite endpoints that combine recurrent non‐fatal events with a terminal event are increasingly used in randomized clinical trials, yet conventional time‐to‐first event analyses may obscure clinically relevant information. We compared two statistical frameworks tailored to such endpoints: the joint frailty model (JFM) and the last‐event ...

Fast Estimation and Valid Statistical Inference for Mixed‐Effect Location‐Scale Models Using Variational Inference

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.
ABSTRACT With the development of modern technology, richer and more intensive longitudinal data are available for researchers to study more complex model structures. The Mixed‐Effect Location‐Scale Model (MELS) is useful for modeling the variance components in such data.

Grain Size Sorting and Steady Bars Formation in Straight Channels—Part 1: Laboratory Experiments

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Surface grain size in gravel‐bed rivers is inherently heterogeneous, with marked spatial variability that remains challenging to predict, even in the presence of regular bedforms. This study investigates surface grain size variability on self‐formed alternate bars at the scale of a single bar unit, and is divided in two parts.

Grain Size Sorting and Steady Bars Formation in Straight Channels—Part 2: Linear Theory

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract This is the second of two papers aimed to investigate grain sorting patterns associated with the formation of steady alternate bars in gravel‐bed rivers. Part 1 presented the analysis of a series of tailored experiments, performed in a mobile bed laboratory flume with fixed, straight banks. The results showed that a consistent pattern of grain
