To address collision challenges between multi-UAVs (unmanned aerial vehicles) during obstacle avoidance, a novel formation control method is proposed.Leveraging the concept of APF (artificial potential field), the proposed approach integrates UAV maneuver constraints with a consensus formation control algorithm, optimizing UAV velocities through th
Based on magnetic field measurements from the satellite CHAMP, a detailed picture could be obtained of the upstream wave (UW) distribution in the topside ionosphere.The low, near-polar orbit of CHAMP, covering all local times, allows the global distribution of this type of pulsation to be revealed.The observations from space are compared to recordi
Abstract Several fish species propel by oscillating the tail, while the remaining part of the body essentially contributes to the overall drag.Since in this case thrust and drag are in a way separable, most attention was focused on the study of propulsive efficiency for flapping foils under a prescribed stream.We claim here that the swimming perfor
Background/Objectives: The change in critically ill patients makes limitation of therapeutic effort (LTE) a widespread practice when therapeutic goals cannot be achieved.We aimed to describe the application of LTE in a post-surgical Intensive Care Unit (ICU), analyze the measures used, the characteristics of the patients, and their evolution.Method
Abstract Background Reliable estimates of mortality according to socioeconomic status play a crucial role in informing the policy debate about social inequality, social cohesion, and exclusion as well as about the reform of pension systems.Linked mortality data have become a gold standard for monitoring socioeconomic differentials in survival.Sever
