Article Synopsis
- - This paper surveys the latest advancements in UAV-based antennas and propagation measurements, emphasizing the flexibility and cost-effectiveness of UAVs for electromagnetic field assessments across various applications, including large-scale antenna testing for 5G/6G networks.
- - It discusses the technical challenges, such as positioning accuracy and antenna alignment, while examining factors that contribute to measurement inaccuracies (0.5 to 1 dB), including GPS errors, UAV vibrations, and ground reflections.
- - The study highlights simulations conducted to understand propagation losses in UAV-to-ground links and concludes with recommendations for future research to enhance the accuracy of antenna measurements and optimize UAV capabilities in this field.
Aquatic debris is considered a major threat to cetaceans. China is subject to severe marine plastic waste that may threaten cetaceans. However, the impact of aquatic debris on cetaceans in Chinese waters has remained poorly studied.

- The study investigates the genetic and brain features linked to vocal learning in mammals by comparing data from the Egyptian fruit bat and 215 other placental mammals.* -
- Researchers found that certain proteins evolve more slowly in vocal learners and identified a specific brain region responsible for vocal motor control in the Egyptian fruit bat.* -
- Using machine learning, they uncovered 50 regulatory elements that are associated with vocal learning, suggesting that losses in these elements played a role in the evolution of vocal learning in mammals.*
Indo-Pacific humpback dolphins (IPHDs) who form resident populations along the Chinese coastline are facing a wide range of anthropogenic disturbances including intense fishing and some populations have been shown to experience a severe decline. Body condition is thought to be a good indicator of health since it is linked to survival and reproductive success. In order to better understand population trends, we investigated whether the body condition of IPHDs is poorer in populations whose status is alarming than in other populations.

For this, PD measurements using the bio-inspired antenna were performed on operational 69 kV potential transformers (PT) in a real substation. After the field experiment, laboratory measurements using the IEC 60270 standard method and a bio-inspired antenna were performed, simultaneously, over the evaluated PT.
