Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract The MIST experiment aims to detect the cosmological 21‐cm signal through sky observations at 25–125 MHz using a wide‐beam antenna. The antenna is mounted above the soil and the beam characteristics are highly dependent on the soil's electrical properties.

Design and Validation of a Passive Solar Tracking Sensor Based on Gnomon Shadow Analysis
International Journal of Photoenergy, Volume 2026, Issue 1, 2026.Solar tracking is essential for efficiency, yet current market solutions present a trade‐off: Active systems are precise but expensive and computationally demanding, while low‐cost passive systems (e.g., LDRs) often lack accuracy. To address this gap, this work presents the design and validation of a passive solar tracking sensor based on gnomon shadow

Graphene Oxide as an Auxiliary UV Photoprotector for Polypropylene
Polymer Composites, Volume 46, Issue 16, Page 14986-15000, 10 November 2025.Auxiliary UV Protection. ABSTRACT This work presents the preparation and characterization of polypropylene (PP)/graphene oxide (GO) nanocomposites by adding photostabilizing additives to obtain materials with enhanced resistance to photodegradation. The synthesized GO (modified Hummers' method) was characterized using state‐of‐the‐art techniques.

Skeleton‐Based Posture Recognition for Home Care From Virtual Unmanned Aerial Vehicle
Expert Systems, Volume 42, Issue 9, September 2025.ABSTRACT This article presents a novel approach for real‐time posture recognition in monitoring scenarios, utilising a virtual camera simulated on a UAV within virtual environments. Leveraging the MediaPipe Pose library, key points of the body skeleton are extracted, focusing on a subset of 8 key points for computational efficiency.
