Composition-dependent trapezoidal quantum barrier effect on efficiency droop in GaN-based light-emitting diodes
We systematically investigated GaN-based light-emitting diodes (LEDs) with composition-dependent trapezoidal quantum barriers (QBs) to analyze the efficiency droop behavior at low and high current densities. T...

Open AccessThe determinants of stroke phenotypes were different from the predictors (CHADS2 and CHA2DS2-VASc) of stroke in patients with atrial fibrillation: a comprehensive approach
Atrial fibrillation (AF) is a leading cause of fatal ischemic stroke. It was recently reported that international normalized ratio (INR) levels were associated with infarct volumes. However, factors other than...
