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
Two Rivers Detention Facility increased to over $40 million and it had cost the City of Hardin $582,595 paid to Two Rivers since 2004 to maintain the facility. Emerald ceased all business in 2017. Montana U.S. Senator Steve Daines has pressed the Bureau of Indian Affairs to contract with the facility, hoping to hold prisoners by January 2018. Two Rivers Detention Facility Two Rivers Regional Detention Facility is a privately operated detention facility located in Hardin, Montana, which was first proposed as economic development in 2004, and was completed in the summer of 2007. It first held prisoners in 2014, substantially under capacity, until
