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

open access: yesJournal of Field Robotics, EarlyView.
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 ...

Exceptionally Elongated Strike‐Slip Rupture Caused by the 2025 MW 7.8 Myanmar Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 6, -Not available-.
Abstract The interplay between fault geometry and rupture behavior remains poorly understood. The 2025 Myanmar earthquake ruptured the Sagaing fault, a major continental strike‐slip fault with simple geometry. We integrated geodetic and teleseismic observations to investigate its rupture process through finite‐fault kinematic inversions and back ...

First LiDAR Observation of Quasi‐Periodic Structures in Mid‐Latitude E‐Region Meteoric Ca+ Layers

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We report the first LiDAR observations of continuous quasi‐periodic (QP) metal density structures in mid‐latitude E‐region meteoric Ca+ layers using an all‐solid‐state LiDAR system in Beijing (40.4°N, 116.0°E). These QP Ca+ structures, with periods of 2–30 min and vertical wavelengths of ∼2–15 km, were primarily observed above 100 km.

Crystal Engineering of Reticular Materials for Gas‐ and Liquid‐Phase Hydrocarbon Separation

open access: yesAdvanced Materials, Volume 38, Issue 16, 17 March 2026.
Crystal engineering enables systematic study of structure/function relationships as exemplified by pore engineering of reticular sorbents, including porous coordination networks and covalent organic frameworks. This review assesses such studies applied across the full scope of industrially relevant hydrocarbon separations to provide insight into how ...
