Beyond static risk scores: dynamic world models simulating patient-specific trajectories to inform preoperative risk mitigation strategies [PDF]
Frontiers in MedicineStatic scores are used in preoperative risk assessment and provide an estimate of a patient’s risk status at a specific time. They do not explicitly represent short-term changes in physiology or recorded care activity.

Simulation of Counter Based DPWM for Implementation on FPGA
AIJR Proceedings, 2021 A Digital Pulse Width Modulation technique based on the counter has been considered for analysis and simulation. It utilizes one of the many functions due to the advanced characteristics already present on the field-programmable gate array (FPGA) which is a huge advantage. Delay Locked Loop (DLL) is one of those features on the FPGA that is used.
