Administration of intravenous ferric carboxymaltose (FCM) for iron‐deficient patients suffering heart failure with reduced ejection fraction (HFrEF) has been associated with transient hypophosphatemia. We sought to investigate and model the effect of intravenous FCM on phosphate levels in iron‐deficient patients with HFrEF. In this single‐center retrospective study, serum phosphate levels, recorded...
Collisions between quadrotor UAVs and the environment often occur, for instance, under faulty piloting, from wind gusts, or when obstacle avoidance fails. Airspace regulations are forcing drone companies to build safer drones; many quadrotor drones now incorporate propeller protection. However, propeller protected quadrotors still do not detect or react to collisions with objects such as walls, poles...
In this paper, we investigate the problem of the dynamics of a quadrotor unmanned aerial vehicle undergoing impact with its environment. This work is motivated by the fact that operation of UAVs (manual or autonomous) carries with it a significant risk of collision with surrounding objects, particularly in unknown, unstructured environments. To make small UAVs more viable and expand their autonomy,...
