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
Aram of the Two Rivers Aram of the Two Rivers Aram of the Two Rivers is an album by bass guitarist Jonas Hellborg that was released in 1999 by Bardo Records. It was recorded live in Syria in 1996 at two venues: the Al Azam Palace in Damascus and one of the oldest caravanserais in Aleppo. Composed of six improvised suites, the album is a fusion of jazz and Arabic music,melding Hellborg's polyrhythms and Middle Eastern modal harmonic structures with authentic sounds of ethnic instruments played by local musicians. Darbukas (Tarek Malas and Mahfouz Al Hosaini) and riqq (Nabil Khaiat) are assisting Hellborg's acoustic bass
