Incidence, risk factors, and outcomes of numerical hypotony and choroidal effusion following PRESERFLO MicroShunt implantation

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the incidence, outcomes, and risk factors of numerical hypotony (NH) and choroidal effusion (CE) following standalone PRESERFLO MicroShunt (PMS) implantation. Methods Primary open‐angle glaucoma (POAG) and pseudoexfoliative glaucoma (PXG) patients with uni‐ or bilateral surgery at a tertiary university hospital were ...

A heuristic-assisted deep reinforcement learning algorithm for flexible job shop scheduling with transport constraints

Complex & Intelligent Systems
Automated guided vehicles (AGVs) are widely used for transportation in flexible job shop (FJS) systems, and their transportation task scheduling has the same substantial impact on production efficiency as machine scheduling does. However, traditional FJS

Whole Blood Transcriptomic Analysis of Sickle Cell Trait

European Journal of Haematology, EarlyView.
ABSTRACT Sickle cell trait (SCT) is the heterozygous carrier state for the HBB missense variant which causes sickle cell disease (SCD). SCT has been associated with increased risk of venous thromboembolism and chronic kidney disease as well as alterations in clinical laboratory parameters. To investigate differential gene expression in SCT, we used RNA

Bi-Objective Integrated Scheduling of Quay Cranes and Automated Guided Vehicles

Journal of Marine Science and Engineering, 2023
Operational efficiency is one of the key performance indicators of a port’s service level. In the process of making scheduling plans for container terminals, different types of equipment are usually scheduled separately.

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

International Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Optimal Scheduling of AGVs in a Reentrant Blocking Job-shop

Procedia CIRP, 2018
Abstract This work presents a mixed integer linear programming (MILP) formulation to find an optimal solution to a small instance of the complex scheduling problem in a make-to-order production. Minimizing the make span, the MILP generates the optimal schedule for the autonomous guided vehicles (AGVs) in a blocking reentrant job shop environment with
