Problem: Phosphor-based LED efficiency losses are due to the heat loss from the Stokes shift and also other phosphor-related degradation issues. Their luminous efficacies compared to normal LEDs depend on the spectral distribution of the resultant light output and the original wavelength of the LED itself. For example, the luminous efficacy of a typical YAG yellow phosphor based white LED ranges from 3 to 5 times the luminous efficacy of the original blue LED because of the human eye's greater sensitivity to yellow than to blue (as modeled in the luminosity function). Due to the simplicity of manufacturing the phosphor method is still the most popular method for making high-intensity white LEDs. The design and production of a light source or light fixture using a monochrome emitter with phosphor conversion is simpler and cheaper than a complex RGB system, and the majority of high-intensity white LEDs presently on the market are manufactured using phosphor light conversion.
What type of emitter is used in non-phosphor-based white LED methods?

Problem: For 2016, U.S. News & World Report ranked BYU as tied for 66th for national universities in the United States. A 2013 Quarterly Journal of Economics study of where the nation's top high school students choose to enroll ranked BYU No. 21 in its peer-reviewed study. The Princeton Review has ranked BYU the best value for college in 2007, and its library is consistently ranked in the nation's top ten No. 1 in 2004 and No. 4 in 2007. BYU is also ranked No. 19 in the U.S. News and World Report's "Great Schools, Great Prices" lineup, and No. 12 in lowest student-incurred debt. Due in part to the school's emphasis on undergraduate research, in rankings for 2008-2009, BYU was ranked No. 10 nationally for the number of students who go on to earn PhDs, No. 1 nationally for students who go on to dental school, No. 6 nationally for students who go on to law school, and No. 10 nationally for students who go on to medical school. BYU is designated as a research university with high research activity by the Carnegie Foundation for the Advancement of Teaching.]] Forbes Magazine ranked it as the No. 1 "Top University to Work For in 2014" and as the best college in Utah.
Who ranked BYU the vest value for college in 2007?

Problem: After the band's six-night stand at New York's Uris Theatre in May 1974, Brian May collapsed and was diagnosed as having hepatitis. While recuperating, May was initially absent when the band started work on their third album, but he returned midway through the recording process. Released in 1974, Sheer Heart Attack reached number two in the United Kingdom, sold well throughout Europe, and went gold in the United States. It gave the band their first real experience of international success, and was a hit on both sides of the Atlantic. The album experimented with a variety of musical genres, including British music hall, heavy metal, ballads, ragtime, and Caribbean. At this point, Queen started to move away from the progressive tendencies of their first two releases into a more radio-friendly, song-orientated style. Sheer Heart Attack introduced new sound and melody patterns that would be refined on their next album, A Night at the Opera.
What was the name of the venue where Brian May collapsed?
