Experimental Physiology, EarlyView.Abstract Long‐duration spaceflight impacts essentially every system in the human body, resulting in multisystem deconditioning that might impair the health and performance of crewmembers, particularly on long‐duration exploration missions to Mars. In this review, we apply the sport science model of athlete monitoring, testing and training to astronauts;

LESO Based Backstepping for Quadrotor Trace Tracking with Tracking Error Constraints [PDF]
Proceedings of the6th International Conference on Mechatronics, Materials, Biotechnology and Environment (ICMMBE 2016), 2016 The trace tracking control for quadrotor aircraft with system uncertainties and constraints for output tracking error is addressed. Uncertainties in quadrotor system is estimated by utilizing linear extended state observer. In addition, the backstepping method using barrier Lyapunov function is designed to compensate for quadrotor uncertainties while ...

On‐Demand Schedules, Worker Absenteeism and Patient Dissatisfaction in Home Care Services
Journal of Operations Management, Volume 71, Issue 8, Page 1090-1114, December 2025.ABSTRACT Service companies often adopt on‐demand scheduling to balance labor costs and fluctuating market demand. However, research shows that such practices can reduce worker productivity and retention. In this study, we examine how on‐demand scheduling affects two critical outcomes: worker absenteeism and patient dissatisfaction.
