Stress Field and Megathrust Strength in the Western Hellenic Subduction System: Insights From the 2024 Mw 5.9 Strofades Earthquake Sequence, Greece

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A M5.9 earthquake occurred on 29 March 2024, offshore near the Strofades Islands, in the western Hellenic Subduction System. Here we present high‐precision earthquake locations and focal mechanisms that suggest the rupture of a NNE‐SSW striking, left‐lateral strike‐slip fault.

Geomorphic Effectiveness of an Extreme Flood in a Mountain River: Evidence From Pre‐ and Post‐Event Surveys in a Subtropical Region of Southern Brazil

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 2254-2341, May 2026.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 3, Page 275-287, May/June 2026.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Smart Livestock: A Federated Learning Based System for Real‐Time Cattle Health, Stress and Water Resource Monitoring

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study introduces a federated learning‐based system for real‐time cattle health and stress detection using smart farming sensors. It preserves data privacy and reduces latency by training models on edge devices. Combining LSTM and CNN, it achieves 93.1% accuracy, enabling early illness detection and promoting sustainable livestock management ...
