Detecting Plateau Zokor (Eospalax baileyi) Mounds in UAV Imagery of Alpine Meadows Using Deep Learning Algorithms

Remote Sensing in Ecology and Conservation, EarlyView.
We developed PZM‐YOLO to automatically detect plateau zokor mounds in UAV imagery of alpine meadows. The model achieved reliable detection of small and densely distributed mounds under complex backgrounds, outperforming the baseline YOLOv5s. This framework supports mound counting, mound position, rodent impact assessment, and grassland restoration ...

Effects of Spring Migration Distance on Tree Swallow Reproductive Success Within and Among Flyways

Frontiers in Ecology and Evolution, 2019
During migration, animals may experience high rates of mortality, but costs of migration could also be manifested through non-lethal carry-over effects that influence individual success in subsequent periods of the annual cycle.

CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use

Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Improving Target Geolocation Accuracy with Multi-View Aerial Images in Long-Range Oblique Photography

Drones
Target geolocation in long-range oblique photography (LOROP) is a challenging study due to the fact that measurement errors become more evident with increasing shooting distance, significantly affecting the calculation results.

Mapping of Polar Areas Based on High-Resolution Satellite Images: The Example of the Henryk Arctowski Polish Antarctic Station

Reports on Geodesy and Geoinformatics, 2017
To produce orthophotomaps or digital elevation models, the most commonly used method is photogrammetric measurement. However, the use of aerial images is not easy in polar regions for logistical reasons.

Presence of Nationally Banned Carbamates and Organophosphate Pesticides in Wild Carnivores, Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT As top predators, terrestrial carnivores face great risk of pesticide exposure and serve as sentinels of environmental contamination. Additionally, terrestrial carnivores are frequently threatened by intentional or secondary poisoning with highly toxic compounds, such as carbamates and organophosphates.
