Abstract As geographic distance increases, species assemblages become more distinct, defining global biogeographic realms with abrupt biogeographic boundaries.Yet, it remains largely unknown to what extent these realms may change because of human-mediated dispersal of species.Focusing on the distributions of 309 non-native ant species, Nasal Care w
Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening condition in which organised thrombi obstruct the pulmonary vessels, causing increased pulmonary vascular resistance, progressive pulmonary hypertension (PH) and right heart failure.The treatment of choice is pulmonary endarterectomy, which restores pulmonary haemodynamics
Dynamic singularities make it difficult to plan the Cartesian path of freefloating robot.In order to avoid its effect, the direct kinematic equations are used for path planning in the paper.Here, the joint position, rate and acceleration are bounded.Firstly, the joint trajectories are parameterized by polynomial or sinusoidal functions.And the two
