AI Article Synopsis
- Recent experiments indicate that excitations can move coherently within light-harvesting complexes, which are important for energy transfer in biological systems.
- The discussion covers the evolution of theoretical models used to study this energy transfer, starting from the foundational models by Förster and Davydov.
- The text also highlights modern theoretical approaches that build on these early models, reflecting advancements in understanding energy dynamics in molecular aggregates.
Article Abstract
Recent experiments on light-harvesting complexes have shown clear indication of coherent transport of excitations in these aggregates. We discuss the theoretical models that have been used to study energy transfer in molecular aggregates, beginning with the early models of Förster and Davydov and ending with the theoretical models of the present day.

Department of Otolaryngology, Faculty of Medicine, Teikyo University, Tokyo, Japan. Electronic address:
Pure tone audiometry including "masking" is the most basic test in audiological medicine. Masking is based on theoretical models of sound perception and propagation and has been widely discussed since the 1950s. In Japan, such discussion has been conducted extensively, starting from early periods up to recent times, with success to enable mathematical simulation, but the achievements have little been disclosed to the English-speaking world.

Institute of History and Ethics in Medicine, School of Medicine and Health, Technical University of Munich, Munich, Germany.
Background: In data-sparse areas such as health care, computer scientists aim to leverage as much available information as possible to increase the accuracy of their machine learning models' outputs. As a standard, categorical data, such as patients' gender, socioeconomic status, or skin color, are used to train models in fusion with other data types, such as medical images and text-based medical information. However, the effects of including categorical data features for model training in such data-scarce areas are underexamined, particularly regarding models intended to serve individuals equitably in a diverse population.
