Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2
Small, EarlyView.The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

Small, EarlyView.We present a van der Waals FeNC‐FET that simultaneously achieves sub‐60 mV/dec steep switching and non‐volatile memory within a single transistor. A CIPS/h‐BN/α‐In2Se3 bi‐ferroelectric gate stack enables a stabilized negative‐capacitance state in FE1 while maintaining the bistable polarization of FE2.

Unusual vertical oscillations of a radiosonde
Weather, EarlyView.In summer 2023 in southern England, several unusual balloon launches were observed which descended for a few minutes before resuming ascent. This unusual vertical oscillation was repeated several times in a ‘roller‐coaster’‐like pattern. This article discusses the behaviour of the balloons.

Wildlife Biology, EarlyView.In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...
