Methods in Ecology and Evolution, Volume 17, Issue 2, Page 272-290, February 2026.Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

Advanced Science, Volume 13, Issue 6, 30 January 2026.This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image

Synthesis to Design Spherical and Deformed Spherical Antenna Array Structures
Microwave and Optical Technology Letters, Volume 68, Issue 1, January 2026.ABSTRACT Antenna array is a key component in various communication systems these days. Rather than various linear and planar array structures, antenna elements are strictly conformed to the curved‐shape surfaces they are mounted in conformal antenna arrays.
