Clear‐Air Turbulence Upstream of a Hydraulic Jump Leading to a Helicopter Accident—A Large Eddy Simulation

open access: yesEarth and Space Science, Volume 13, Issue 10, October 2026.
Abstract This study investigates clear‐air turbulence that triggered a helicopter accident in the lee of a mountain range near Koriyama, Japan, on 1 February 2020. Using numerical weather prediction models with horizontal resolutions of 1 km and 100 m, we examined the environmental conditions and mechanisms responsible for the turbulence.

Auto‐STIV: A Deep Learning Framework for Fully Autonomous Two‐Dimensional Streamflow Velocity Vector Field Estimation

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract Accurate and continuous streamflow monitoring can support effective water resource management, yet substantial gaps persist in national streamgage networks due to operational challenges and costs. Non‐contact, image‐based techniques such as Space‐Time Image Velocimetry (STIV) offer a safe, scalable and, cost‐effective alternative for measuring

Reaction‐Driven Crack Propagation Controlled by Vein Extension in a Dilute Fracture System

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Permanent mineral trapping of CO2 ${\text{CO}}_{2}$ in ultramafic rocks can be accelerated if carbonate precipitation wedges open microcracks and sustains crack growth, thereby increasing permeability and reactive surface area. We develop a vein‐extension controlled model for carbonation reaction‐driven cracking in a dilute fracture system ...

Décollement Rheology Controls Crustal Deformation on Early Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The circum‐Tharsis wrinkle ridge system represents one of the strongest tectonic imprints of early Mars, formed as the planet's largest volcanic province reshaped the lithosphere and redistributed stresses across thousands of kilometers. The coherent spatial pattern of these ridges suggests deformation governed by a laterally continuous basal ...

Emergence of Deviance Detection in Cortical Cultures Through Maturation, Criticality, and Early Experience [PDF]

open access: yesEur J Neurosci
Deviance detection (DD) emerges in dissociated cortical cultures around DIV15 and remains detectable through maturation. Near‐critical network dynamics are associated with stronger DD responses. Early structured stimulation was associated with descriptive differences in response timing and DD strength, although mature‐stage group differences were not ...

Cohesive Surface Layers Transform Braided Channels Into Self‐Sustaining Meandering Channels With Repeated Cutoffs

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Meandering rivers are ubiquitous on Earth and other planetary surfaces, yet generating dynamically active meandering channels that can sustain meandering patterns for multiple flow cycles without introduced external disturbances remains challenging in laboratory conditions. Here, we use flume experiments to investigate how a synthetic cohesive
