Adaptive Seamless Phase II/III Randomization Test Considering Treatment Group Selection Based on Short–Term Binary Outcomes

Statistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT Recently, adaptive seamless phase II/III designs (ASDs) have gained attention because they improve the efficiency of drug development. In an ASD, a phase II trial, which explores the dose–response relationships and identifies treatments for the phase III trial, is combined with a phase III trial, which aims to demonstrate the efficacy and ...

Runoff Reconstructions and Future Projections Indicate Highly Variable Water Supply From Pacific Rim Water Towers

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Anthropogenic climate change affects regional hydrological cycles and poses significant challenges to the sustainable supply of freshwater. The Central China water tower (CCWT) is the key source region feeding the Yangtze and Yellow Rivers, and its runoff is indispensable for the surrounding mega‐city clusters. Here we present a reconstruction

Evaluating the Performance of Uni‐ and Multivariate Bias Correction Techniques: Challenges in Preserving Temporal and Dependence Structures

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Global Climate Models (GCMs) are essential for simulating past and future climates but suffer from systematic biases and coarse resolution, limiting direct applications. Bias correction (BC) and downscaling, using dynamical or statistical methods, address these issues. Quantile mapping (QM)‐based BC is widely used, yet it distorts dependencies,
