UV‐Enhanced Scanning Electron Microscope: Toward Orientation and Electron Work Function Imaging
A complementary deep‐UV illumination system for scanning electron microscope (SEM) is developed at a robust instrument level with precise mechanical control of the focused beam's position and tilt. New SEM imaging modalities are discussed, and future prospects of introducing polarised UV irradiation are outlined by numerical simulations of electron ...

Control System for the Navigation of the Agricultural Robots: A Review
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Fewer devil rays in the sea: Evidence of declining mobulid populations off India's coast
Manta and devil rays are declining globally due to targeted and incidental capture, but species‐specific assessments are limited by unmonitored fisheries. Using morphometric, demographic, and fishery metrics, we show for the first time in India long‐term (2013–2023) declines in Mobula mobular, Mobula tarapacana, Mobula birostris, and Mobula thurstoni ...

Examining the efficacy of a sanctuary to protect sharks in the Galapagos Marine Reserve
Abstract In 2016, Ecuador established a no‐take marine sanctuary in the northern portion of the Galapagos Marine Reserve (GMR), ostensibly to protect sharks. Arguably because of this, experimental longlining was permitted in the rest of the reserve as part of a compensation package to local fishers. Considering this agreement and very low bycatch rates
