Yasuhiko Arakawa Yasuhiko Arakawa Yasuhiko Arakawa (Japanese , "Arakawa Yasuhiko"; born 6 November 1952) is a Japanese physicist. His research focuses on semiconductor physics, including growth of nanostructures and their optoelectronic applications. Among his main achievements are the proposal of the concept of quantum dots and their application to quantum dot lasers, the observation of exciton-polariton Rabi-splitting in a semiconductor microcavity, or, recently, the first 3D photonic crystal nanocavity lasers with quantum dot gain. Yasuhiko Arakawa received a B.S. degree in 1975 and a Ph.D. degree in 1980, respectively, from the University of Tokyo, both in Electronics Engineering. In 1981 he became

The panels appear as a constellation of views concerning the nature of meaning that made be characterized in broad stroke as "holistic" or as entailments of a holistic view concerning meaning. To date, two editions of "The Mechanism of Meaning" have been made and many of the panels incorporate collaged elements. Arakawa and Madeline Gins are co-founders of the Reversible Destiny Foundation, an organization dedicated to the use of architecture to extend the human lifespan. They have co-authored books, including "Reversible Destiny", which is the catalogue of their Guggenheim exhibition, "Architectural Body" (University of
