A Novel Method of Color Appearance Simulation Using Achromatic Point Locus With Lightness Dependence
i-Perception, 2018 The purpose of the present study is to propose a simple algorithm for color appearance simulation under a color illuminant. Achromatic point is a chromaticity of rays that appear neither red nor green, neither blue nor yellow under a given illuminant ...

The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1
Molecular Microbiology, Volume 125, Issue 5, Page 389-411, May 2026.A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...

Time‐Resolved Photoluminescence Lifetime Measurements of Organic Photovoltaic Materials
physica status solidi (a), Volume 223, Issue 8, 22 April 2026.A nondestructive measurement technique utilizing time‐correlated single photon counting (TCSPC), based on photoluminescence statistics is presented for organic photovoltaic materials. This method identifies a comparative parameter independent of absorber layer thickness and the presence of transport layers (ETL/HTL).
