The traditional folk music of Cyprus has several common elements with Greek, Turkish, and Arabic music including Greco-Turkish dances such as the sousta, syrtos, zeibekikos, tatsia, and karsilamas as well as the Middle Eastern-inspired tsifteteli and arapies. There is also a form of musical poetry known as chattista which is often performed at traditional feasts and celebrations. The instruments commonly associated with Cyprus folk music are the bouzouki, oud ("outi"), violin ("fkiolin"), lute ("laouto"), accordion, Cyprus flute ("pithkiavlin") and percussion (including the "toumperleki"). Composers associated with traditional Cypriot music include Evagoras Karageorgis, Marios Tokas, Solon Michaelides and Savvas Salides. Among musicians is also the acclaimed pianist Cyprien Katsaris and composer and artistic director of the European Capital of Culture initiative Marios Joannou Elia.
Traditional Cyprus music has what other types of genres in common?

James Liebman, a professor of law at Columbia Law School, stated in 1996 that his study found that when habeas corpus petitions in death penalty cases were traced from conviction to completion of the case that there was "a 40 percent success rate in all capital cases from 1978 to 1995." Similarly, a study by Ronald Tabak in a law review article puts the success rate in habeas corpus cases involving death row inmates even higher, finding that between "1976 and 1991, approximately 47 percent of the habeas petitions filed by death row inmates were granted." The different numbers are largely definitional, rather than substantive. Freedam's statistics looks at the percentage of all death penalty cases reversed, while the others look only at cases not reversed prior to habeas corpus review.

In 1957, Braunstein further demonstrated that the rudimentary devices could be used for non-radio communication across a short distance. As noted by Kroemer Braunstein".. had set up a simple optical communications link: Music emerging from a record player was used via suitable electronics to modulate the forward current of a GaAs diode. The emitted light was detected by a PbS diode some distance away. This signal was fed into an audio amplifier, and played back by a loudspeaker. Intercepting the beam stopped the music. We had a great deal of fun playing with this setup." This setup presaged the use of LEDs for optical communication applications.
 The current in radio communication had to go through what type of component?
A:
unanswerable
