Multi-Agent Reinforcement Learning-Based Computation Offloading for Unmanned Aerial Vehicle Post-Disaster Rescue.

School of Computer Science and Engineering, Northeastern University, Shenyang 110000, China.
Natural disasters cause significant losses. Unmanned aerial vehicles (UAVs) are valuable in rescue missions but need to offload tasks to edge servers due to their limited computing power and battery life. This study proposes a task offloading decision algorithm called the multi-agent deep deterministic policy gradient with cooperation and experience replay (CER-MADDPG), which is based on multi-agent reinforcement learning for UAV computation offloading.

Separation-related behaviours (SRBs) in dogs () often indicate poor welfare. Understanding SRB risk factors can aid prevention strategies. We investigated whether early-life experiences and dog-owner interactions affect SRB development.

Background: Covered stent correction for a sinus venosus atrial septal defect (SVASD) was first performed in 2009. This innovative approach was initially viewed as experimental and was reserved for highly selected patients with unusual anatomic variants. In 2016, increasing numbers of procedures began to be performed, and in several centers, it is now offered as a standard of care option alongside surgical repair.

Int J Gynaecol Obstet
December 2024
Department of Obstetrics and Gynecology, Bordeaux University Hospital, Bordeaux, France.
Objective: To evaluate the prevalence and risk factors of maternal dissatisfaction 2 days after a singleton vaginal delivery at or near term.
Methods: We conducted a planned ancillary cohort study of the TRanexamic Acid for Preventing Postpartum Hemorrhage After Vaginal Delivery (TRAAP) randomized controlled trial. Maternal dissatisfaction, related to the birth and to the subsequent hospital stay, was assessed 2 days postpartum by two self-administered questions: "Are you satisfied with the care you received during your child's birth?" and "Are you satisfied with the care you have received during your hospital stay?".
Learning from missing feedback: Exemplar versus model-based methods.

Article Synopsis
- Feedback in decision-making often focuses on positive outcomes, leading to a bias in how people learn to differentiate between good and bad choices.
- We explore two approaches to overcoming this bias: model-based methods that adjust their understanding based on available feedback and exemplar models that fill in gaps with hypothetical negative outcomes.
- Our experiments reveal that people generally lean towards using exemplar models with imputation to address missing feedback, but a significant number also apply Bayesian models, indicating varied strategies influenced by uncertainty in the task.
