Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

Journal of Field Robotics, Volume 43, Issue 3, Page 1646-1660, May 2026.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

First Isolation of Yersinia enterocolitica From a Sea Turtle: A Case Report in Caretta caretta

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
1. First isolation of Yersinia enterocolitica, a zoonotic bacterium, in a loggerhead sea turtle (Caretta caretta), identifying it as the likely cause of severe colitis, hepatitis, and fatal sepsis. 2. The findings highlight that sea turtles and the marine environment can act as reservoirs for Y. enterocolitica: this poses a “One Health” threat. 3.

Cycloidal Magnetic Gear Speed Reducer

Modern Mechanical Engineering, 2013
A cycloidal speed reducer employing gears with permanent magnets acting as teeth is described. The magnets, which have their axes radially oriented in both the orbiting gear and the fixed internal gear, are inserted in holes drilled in nonmagnetic rims without protruding from the cylindrical exposed surfaces. Because the orbiting gear is not restrained

Field‐Data‐Based Wind Turbine Reliability Modelling: Quantifying Effects of Operating Age, Design and Technological Development

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT As wind energy continues to expand, ensuring the reliability of wind turbines is critical for optimising operational efficiency and minimising downtime. Based on maintenance data from over 1,000 onshore and offshore wind turbines covering more than 4200 operating years, this study presents an analysis of wind turbine failure behaviour over ...

COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1617-1627, May 2026.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.
