Ambient contrast ratio of quantum-dot color-converted micro-LED displays
Results in Physics, 2023 Pixelated quantum dot color conversion layer (PQDCCL) is the most promising approach to realize a full-color micro-LED display. However, the QD excitation by ambient light has non-negligible impact on the ambient contrast ratio (ACR) and the display ...

Contrast‐to‐noise ratios of diffusion anisotropy indices [PDF]
Magnetic Resonance in Medicine, 2005 AbstractThe degree of diffusion anisotropy in different brain regions is usually measured by a diffusion anisotropy index (DAI) such as relative anisotropy (RA) and fractional anisotropy (FA). FA has been reported to have a higher contrast‐to‐noise ratio (CNR) than RA. The present work compares the CNRs of seven DAIs in theoretical propagation‐of‐error

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.
