The Anamosa State Penitentiary Cemetery, also known as the Iowa Men's Reformatory Cemetery or Boot Hill Cemetery, is located west of Anamosa, Iowa, United States.
 The first cemetery associated with the Iowa Men's Reformatory, now a penitentiary, was begun in 1876 at Prison Farm No. 1 or possibly at Farm No. 5.
 Its exact location is unknown.
 The graves are of those prisoners whose bodies were left unclaimed or were not taken to one of the state's medical colleges.
 They were buried in common graves that contained up to eight bodies.
 Tall limestone markers were placed at each grave and contained the prisoner's name and death date.
 They were moved here when this cemetery was established in 1914.
 Subsequent graves hold individual bodies, and are marked with shorter limestone markers with the prisoner's name, age, date of death, and sometimes their prison number.
 They are in three different styles.
 Two styles are upright stones, one with a triangular top and the other with a rounded top.
 They were used from 1914 to the 1940s.
 The third style of stone is a flat, horizontal marker that was used from the 1940s to the present.
Musica ricercata is a set of eleven pieces for piano by György Ligeti.
 The work was composed from 1951 to 1953, shortly after the composer began lecturing at the Budapest Academy of Music.
 The work premiered on 18 November 1969 in Sundsvall, Sweden.
 Although the ricercata (or ricercar) is an established contrapuntal style (and the final movement of the work is in that form), Ligeti's title should probably be interpreted literally as "researched music" or "sought music".
 This work captures the essence of Ligeti's search to construct his own compositional style "ex nihilo", and as such presages many of the more radical directions Ligeti would take in the future.
Death trajectory refers to the pattern of dying when a patient is given a projected death date with limited or no medical recourse for the remaining existence of the individual's life.
 The death trajectory is dependent on the cause of death, whether it is sudden death, chronic illness, or the steady decline in health due to senescence (aging).
 Death trajectory is analyzed in two separate aspects: duration and shape.
 Duration refers to the period of time a patient has to live, which can be anywhere from imminent death to several months.
 Shape refers to how that duration is then graphed.
 In other words, the shape is "the course of dying, its predictability, and whether death is expected or unexpected".

The Pleiades Dances are a series of solo piano pieces written by contemporary Japanese composer Takashi Yoshimatsu.
 They are, in the words of the composer, "a newly conceived set of preludes for the modern piano which takes its material from the seven colours of the rainbow, the seven pitches of church modes, and seven metrical units ranging from three to nine beats."
 Currently ranging from I to IX, these works were written between 1986 and 2001.
 Each set of Pleiades Dances contains 7 movements, which "are not placed in the order in which they appear in the work for any specific structural or contextual reasons, nor should too much be read into the curious titles [he gave] them."
 Yoshimatsu, in the preface to these works, encourages free interpretation of these pieces "including tempo, dynamics and frequency of repetition," and suggests that "It may also be enjoyable to play along with the rhythm by a small percussion instrument like the triangle or the tambourine."
 Each set, however, seems internally dependent, so that within one set of 7, the order can be freely arranged, but the character of each set differs noticeably between each set.
 Pleiades Dances set no.
 VIII is a piano arrangement of the 1999 work for 20 string koto: "Subaru".
 Yoshimatsu augmented the titles of the movements of Subaru to remain consistent with the dance-suite attitude of the other sets of Pleiades Dances.
