*-algebra
In mathematics, and more specifically in abstract algebra, a *-algebra (or involutive algebra) is a mathematical structure consisting of two involutive rings R and A, where R is commutative and A has the structure of an associative algebra over R. Involutive algebras generalize the idea of a number system equipped with conjugation, for example the complex numbers and complex conjugation, matrices over the complex numbers and conjugate transpose, and linear operators over a Hilbert space and Hermitian adjoints.
Terminology
*-ring
In mathematics, a *-ring is a ring with a map * : A → A that is an antiautomorphism and an involution.
More precisely, * is required to satisfy the following properties:
for all x, y in A.
This is also called an involutive ring, involutory ring, and ring with involution. Note that the third axiom is actually redundant, because the second and fourth axioms imply 1* is also a multiplicative identity, and identities are unique.
Ring (Suzuki novel)
Ring (リング, Ringu) is a Japanese mystery horror novel by Koji Suzuki, first published in 1991, and set in modern-day Japan. It was the basis for a 1995 television film (Ring: Kanzenban),a television series (Ring: The Final Chapter), a film of the same name (1998's Ring), and two remakes of the 1998 film: a South Korean version (The Ring Virus) and an American version (The Ring).
Plot synopsis
After four teenagers mysteriously die simultaneously in Tokyo, Kazuyuki Asakawa, a reporter and uncle to one of the deceased, decides to launch his own personal investigation. His search leads him to "Hakone Pacific Land", a holiday resort where the youths were last seen together exactly one week before their deaths. Once there he happens upon a mysterious unmarked videotape. Watching the tape, he witnesses a strange sequence of both abstract and realistic footage, including an image of an injured man, that ends with a warning revealing the viewer has a week to live. Giving a single means of avoiding death, the tape's explanation ends suddenly having been overwritten by an advertisement. The tape has a horrible mental effect on Asakawa, and he doesn't doubt for a second that its warning is true.
Ringtone
A ringtone or ring tone is the sound made by a telephone to indicate an incoming call or text message. Not literally a tone nor an actual (bell-like) ring any more, the term is most often used today to refer to customizable sounds used on mobile phones.
Background
A phone “rings” when its network indicates an incoming call and the phone thus alerts the recipient. For landline telephones, the call signal can be an electric current generated by the switch or exchange to which the telephone is connected, which originally drove an electric bell. For mobile phones, the network sends the phone a message indicating an incoming call. The sound the caller hears is called the ringback tone, which is not necessarily directly related.
The electromagnetic bell system is still in widespread use. The ringing signal sent to a customer's telephone is 90 volts AC at a frequency of 20 hertz in North America. In Europe it is around 60-90 volts AC at a frequency of 25 hertz. Some non-Bell Company system party lines in the US used multiple frequencies (20/30/40 Hz, 22/33/44 Hz, etc.) to allow "selective" ringing.
Gümüş (TV series)
Gümüş (Turkish for "Silver") is a Turkish melodrama originally broadcast in Turkey by Kanal D from 2005 to 2007. The sudser became a pop-culture phenomenon when it dubbed in Arabic language and aired across the Arab world as "Noor" (Arabic for "light") in 2008. The show which MBC execs dubbed from Turkish into Arabic using a colloquial Syrian dialect rather than formal, classical Arabic, followed the travails of a simple young woman "Gümüş," played by Songül Öden, who marries into a wealthy family.
The success of "Noor" for MBC has sparked a boom in dubbed Turkish dramas across many leading Arab sat-casters. MBC even launched a pay TV channel in partnership with pay TV platform Showtime Arabia entirely dedicated to "Noor" that allows viewers to watch episodes of the sudser around the clock.
The dizzying pop-cultural phenomenon surrounding the series has encouraged the broadcaster further to make a film out of the Turkish soap. The feature version, which MBC will co-produce with Turkish shingle Momentum Prods., will have a budget in the $2.5 million-3.5 million range and will also be shot in Turkish before being dubbed into Arabic. The project will reunite Turkish thespians Kıvanç Tatlıtuğ and Songül Öden, who captured the hearts of Arab audiences in their husband-and-wife roles of Muhannad and Noor, respectively.

¡Three Amigos!
¡Three Amigos! is a 1986 American comedy film directed by John Landis and written by Lorne Michaels, Steve Martin, and Randy Newman. The plot is loosely based on Akira Kurosawa's 1954 film Seven Samurai and the subsequent western adaptation The Magnificent Seven. Steve Martin, Chevy Chase, and Martin Short star as the title characters, three silent film stars who are mistaken for real heroes by the suffering people of a small Mexican village and must find a way to live up to their reputation.
Plot
In 1916, the notorious bandit El Guapo (Alfonso Arau) and his gang of thugs are collecting protection money from the small Mexican village of Santo Poco. Carmen (Patrice Martinez), daughter of the village leader, searches for someone who can come to the rescue of her townspeople. While visiting a small village church, she watches a silent film featuring "The Three Amigos" and, believing them to be real heroes, sends a telegram to Hollywood asking them to come and stop El Guapo and offering a substantial payment she cannot afford, believing that they will refuse it and say "Our reward is that justice has been done", as happened in the film she saw. However, the telegraph operator heavily edits her message since she has very little money to pay for it, rendering it ambiguous.
