Assessment of LiDAR-Based Sensing Technologies in Bird–Drone Collision Scenarios
Published 2024-12-01“…One of the key aspects to consider here is the availability of robust solutions to avoid tactical conflicts between drones and other flying elements, such as other drones or birds. Bird detection is a relatively underexplored area, but due to the large number of birds, their shared airspace with drones, and the fact that they are non-cooperative elements within an air traffic management system, it is of interest to study how their detection can be improved and how collisions with them can be avoided. …”

Hologenomic data generation and analysis in wild vertebrates
Published 2025-01-01“…We also report that birds and bats both have substantially lower microbial DNA fractions and a higher degree of sample‐to‐sample variability compared to amphibians, reptiles and non‐flying mammals. Based on these data, we provide suggestions to the field for robustly and efficiently generating hologenomic data from wild vertebrates.…”

Sensory quiescence induces a cell-non-autonomous integrated stress response curbed by condensate formation of the ATF4 and XRP1 effectors
Published 2025-01-01“…Unlike during canonical ISR, however, the ATF4 and XRP1 transcription factors are enriched in cytosolic granules that are positive for RNA and the stress granule markers Caprin, FMR1, and p62, and are reversible upon restoration of vision for blind flies. Cytosolic restraint of the ATF4 and XRP1 transcription factors dampens expression of their downstream targets including genes of cell death pathways activated during chronic cellular stress and thus constitutes a chronic stress protective response (CSPR). …”
