Reed Nevus (Pigmented Spindle Cell Nevus) in an 11-Month-Old Japanese Infant
, 2012 Reed nevus (pigmented spindle cell nevus) is a nevus with the histopathological features of abundant melanin, monomorphic spindle-epithelioid melanocytes, spindle cell nests confined within the epidermis and papillary dermis, and occasional upward ...

Optimal number of pigments in photosynthetic complexes [PDF]
New J. Phys. 14, 093017 (2012), 2012 We study excitation energy transfer in a simple model of photosynthetic complex. The model, described by Lindblad equation, consists of pigments interacting via dipole-dipole interaction. Overlapping of pigments induces an on-site energy disorder, providing a mechanism for blocking the excitation transfer.

Hyperspectral Pigment Analysis of Cultural Heritage Artifacts Using the Opaque Form of Kubelka-Munk Theory [PDF]
Proc. SPIE 10986, Algorithms, Technologies, and Applications for
Multispectral and Hyperspectral Imagery XXV, 1098611, 2019, 2021 Kubelka-Munk (K-M) theory has been successfully used to estimate pigment concentrations in the pigment mixtures of modern paintings in spectral imagery. In this study the single-constant K-M theory has been utilized for the classification of green pigments in the Selden Map of China, a navigational map of the South China Sea likely created in the early
