Concomitant Gradient Effects Across Field Strengths and Gradient Amplitudes: Improved Estimation of Errors and Correction of Concomitant Dephasing and Diffusion Weighting

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1178-1191, September 2026.
ABSTRACT Purpose Deleterious effects from concomitant gradients are amplified at lower field strengths and stronger gradients. We aimed to show the signal errors caused by concomitant gradients across a wide range of hardware configurations and propose corrections that can be applied during experimental design and analysis.

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

open access: yesFisheries Oceanography, Volume 35, Issue 5, Page 760-776, September 2026.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.

Enchanting the Otherwise: Magical Realism and the Gendered Ontologies of Organizational Becoming

open access: yesGender, Work &Organization, Volume 33, Issue 5, Page 1707-1719, September 2026.
ABSTRACT This paper enacts a feminist‐posthumanist reimagining of gender as ontological disturbance, using magical realism not as metaphor but as epistemological method. Rejecting representational logics and the managerial rationalities of organizational realism, we advance gender not as identity or role but as spectral interference—a transversal ...

Assessment of MR‐Induced Heating Effects in Four Common Veterinary Implants at 1.5 and 3.0 T: A Phantom Study

open access: yesVeterinary Radiology &Ultrasound, Volume 67, Issue 5, September 2026.
ABSTRACT Quantitative evaluation of implant‐related heating in magnetic resonance imaging (MRI) is well standardized in human medicine, whereas evidence in veterinary medicine remains scarce. To address this gap, we measured radiofrequency (RF)‐induced heating of four used veterinary implants under controlled conditions on clinical 3.0 and 1.5 T MRI ...

Quantifying Daily Vertical Heat Flux in the Loop Current System: A Quasi‐Lagrangian Assessment of Frontal Hotspots

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Vertical heat exchange within the upper ocean critically influences regional climate but remains difficult to observe directly. In the Gulf of Mexico, the Loop Current and its associated eddies significantly enhance this exchange. High‐resolution glider observations reveal that this transport is dominated by sub‐daily variability an order of ...

Shannon Entropy and Lévy Statistics for Machine Learning‐Assisted Spectral Sensing in Random Fiber Lasers With Magnetic Core–Shell Nanoscatterers

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
Random laser emission was observed in a polymer optical fiber structure doped with magnetic Fe3O4@SiO2 core–shell nanoparticles. A direct relationship was demonstrated between Shannon entropy and Lévy statistics regarding intensity fluctuations in the emission modes. The analysis indicated a potential application in a proposed magnetic field and energy

On–Off Switchable Micromotors for Use in Steerable Microvehicles

open access: yesAdvanced Robotics Research, Volume 2, Issue 4, August 2026.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Engineering Neuronal Network Connectivity Through Precise and Scalable Electrical Modulation

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
This study presents a scalable all‐electrical method for precise neuronal‐circuit reconfiguration based on high‐density microelectrode arrays. By employing biologically inspired plasticity rules, targeted connectivity changes were successfully induced and quantified across diverse neuronal preparations.
