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

Journal 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 ...

Random-Training-Assisted Pilot Spoofing Detection and Security Enhancement

IEEE Access, 2017
The pilot spoofing attack is considered as an active eavesdropping activity launched by an adversary during the reverse channel training phase. By transmitting the same pilot signal as the legitimate user, the pilot spoofing attack is able to degrade the

Ruthenium Nanoparticle‐On‐Cavity Refractory Thermoplasmonics for Broadband and Spectral‐Selective Solar Photothermal Conversion

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
We identify ruthenium as a refractory plasmonic material exhibiting dual ENZ optical topological transitions and dual plasmonic resonances spanning from visible to infrared region with high imaginary permittivity. We establish a nanoparticle‐on‐cavity (NPoC) resonance mode and realize a NPoC selective solar absorber using cost‐effective additive ...
