Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate

Laser &Photonics Reviews, EarlyView.
Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.

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

Journal 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 ...

Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

Journal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

Characteristics of unique cap, Tsurushi and Hata clouds around Mount Fuji

Weather, EarlyView.
Distinct clouds, such as cap clouds, Tsurushi (a type of lenticular cloud) and Hata (banner cloud‐like clouds), frequently form around Mount Fuji, an isolated peak with a slightly elliptical conical shape. Here, we examine their characteristics and occurrence patterns.
