Flood‐Scale Bedload Transport Dynamics From Acoustic Monitoring Compared With 2D Hydro‐Sedimentary Modeling

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Accurate estimation of bedload fluxes is critical to understanding sediment transport processes and associated channel evolution in gravel‐bed rivers, however, traditional direct measurements using samplers are time‐consuming and complex. To overcome these limitations, new indirect methods have been developed to estimate fluxes from bedload ...

Saturation Effects in Narrowband Resonance Lidar Measurements, Part 2: Potassium Lidar Systems and Experimental Results

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Resonance lidars targeting the D1 ${D}_{1}$ resonance line of potassium at 770 nm have been employed over the past 5 decades to yield numerous insights into the dynamics of the middle and upper atmosphere. It has long been recognized that these measurements can be severely affected by nonlinear behavior in the scattering process, that is ...

Jovian Auroral Proton Precipitation

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...

Hybrid Equilibrium Element Formulation for Large Displacement Nonlinear Elasticity

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT The present paper proposes an equilibrium‐based finite element formulation for the analysis of large displacement and large strain nonlinear elasticity problems. The proposed formulation is based on the Hybrid Equilibrium Element (HEE) and is developed in an updated Lagrangian framework.

Coarse Sediment Transport in a Near‐Terminus Subglacial Channel

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We present the first large‐sample, spatially resolved measurements of coarse sediment transport within a subglacial meltwater channel. We released 324 radio‐tagged pebbles into a near‐terminus channel of Glacier d’Otemma, Switzerland, and monitored their positions through 10–50 m of ice during the mid to late melt season.

Development of a Lensless Compact Optical System for Ultrasensitive Nanomaterial Detection in Liquid Media via Exploiting Multiple Light Scattering

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
This work presents a lensless speckle‐based platform that exploits multiple light scattering for precise nanoparticle detection in liquid media. The proposed method enables ultrasensitive detection at concentrations far below conventional DLS limits and provides semiquantitative size estimation, offering a cost‐effective and field‐deployable approach ...
