For safe path planning of unmanned aerial vehicles (UAVs) in a three-dimensional (3D) environment with USB multiple threats, first, a cost function is introduced according to the terrain constraints and UAV overall performance constraints of the path planning problem.Then, improved nonlinear dynamic inertia weights (INDIW) are introduced into the p
Background: The role of race within tribal communities is a contentious topic, and some of this acrimony emerged from 19th-century Indian policies rooted in scientific racism.There has been relatively little written on the role of intermarriage within indigenous communities.Methods: We link household data from the Eastern Band of Cherokee Indians i

A leading notion is that language skill acquisition declines between childhood and adulthood.While several lines of evidence indicate that declarative ("what", explicit) memory undergoes maturation, it is commonly assumed that procedural ("how-to", implicit) memory, in children, is well established.The language superiority of children has been ascr
Cast Ni-Si-B alloys have the potential for high-temperature applications because of their high resistance to wear, impact, corrosion, and oxidation at elevated temperatures due to an appropriate balance of hard phases and austenite that ensures a good compromise between toughness and hardness.In this work, NiSi3B2 specimens, fabricated by the lost-
