ICESat-2 altimeter data could be used to estimate sea ice freeboard and thickness values with a higher measuring accuracy than that achievable with data provided by previous altimeter satellites.This study developed an improved algorithm considering variable lead proportions based on the lowest point method to derive the sea surface height for the
Raccoon dogs (Nyctereutes procynoides) are canids indigenous to Eastern Asia being one of the most invasive non-native animals in Europe and potential vectors for several hazardous parasitic and viral diseases.To present, there is a lack of studies regarding objective techniques used to appreciate the integrity and functionality of the nervous syst

Rotor-craft style UAV, such as the quadrotor, has become increasingly popular with researchers due to its advantages over fixed-wing UAV.The quadrotor is highly maneuverable, can 2-Layer Wood Sign perform vertical take-off and landing (VTOL), and can hover flight capability.Nevertheless, handling the quadrotor complex, highly nonlinear dynamics is
