Nonlinear Dynamics of a Passive Walker: Bifurcation and Stability Insights With Spring and Damper Mechanics

International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 357-369, June 2026.
ABSTRACT This study explores the nonlinear dynamics associated with a passive dynamic walker (PDW), focusing on the bifurcation and stability insights derived from spring and damper mechanics. PDWs, which rely on gravity for stable locomotion without active control, exhibit a rich spectrum of behaviors, from periodic to chaotic motion.

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.

Mesoscale and Submesoscale Variability in the Indian Ocean

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.

Information Flow in Geophysical Systems

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract We present a new framework for analyzing the evolution of information in geophysical systems. Understanding how information, and its counterpart, uncertainty, propagates is central to predictability studies and has significant implications for applications such as forecast uncertainty quantification and risk management. It also offers valuable

TNF Pathway‐Mediated Tolerogenic T‐Cell Trajectory Driven by Allergen Immunotherapy

Allergy, Volume 81, Issue 6, Page 2184-2197, June 2026.
The study shows that AIT re‐establishes local immune equilibrium by restoring Th17/Treg balance, while circulating Th17 cells remain functionally impaired. The transition from pro‐inflammatory Th17 to regulatory T cell states during AIT identifies Tr17 cells as an intermediate cell population.
