Posterior migration of an Ahmed glaucoma valve: A case report of a rare postoperative complication [PDF]

American Journal of Ophthalmology Case Reports
Purpose: Ahmed glaucoma valve (AGV) migration is a rare postoperative complication after AGV implantation. We report a single case of AGV posterior migration in the early postoperative period.

Research on AGV path tracking method based on global vision and reinforcement learning

Science Progress, 2023
As the key to the movement of automated guided vehicle (AGV), the design of control algorithm directly affects whether AGV can follow the preset path. Aiming at the difficulty of AGV control, an AGV path tracking control method based on global vision and

Dynamic chain for scheduling of the multi-AGV systems with load-aware motion profiling [PDF]

Scientific Reports
In dynamic warehouse environments, conventional multi-AGV systems would adopt fixed-motion planning that does not take into account the physical constraints of vehicles and products, and therefore results in random collisions and inefficient routing.

Corneal endothelial cell changes and surgical results after Ahmed glaucoma valve implantation: ciliary sulcus versus anterior chamber tube placement

Scientific Reports, 2021
We compared the changes in corneal endothelial cells and surgical outcomes after Ahmed glaucoma valve (AGV) implantation with the valve tip inserted either into ciliary sulcus (CS) or anterior chamber (AC). We retrospectively reviewed the medical records
