Disc (band)

Disc is an experimental group formed by Miguel Depedro (Kid606), Jason Doerck (J Lesser), M. C. Schmidt and Drew Daniel (Matmos). The group was most active between 1997 and 1999.

To produce their sound, digital media (DATs, CDs) were etched and painted, or used in broken players to produce new sounds. In Gaijincd4, a "bonus" nonfunctional CD was included to suggest a multimedia disc. The double LP Transfer consisted entirely of locked grooves.

+/- (band)

+/-, or Plus/Minus, is an American indietronic band formed in 2001. The band makes use of both electronic and traditional instruments, and has sought to use electronics to recreate traditional indie rock song forms and instrumental structures. The group has released two albums on each of the American indie labels Teenbeat Records and Absolutely Kosher, and their track "All I do" was prominently featured in the soundtrack for the major film Wicker Park. The group has developed a devoted following in Japan and Taiwan, and has toured there frequently. Although many artists append bonus tracks onto the end of Japanese album releases to discourage purchasers from buying cheaper US import versions, the overseas versions of +/- albums are usually quite different from the US versions - tracklists can be rearranged, artwork with noticeable changes is used, and tracks from the US version can be replaced as well as augmented by bonus tracks.

Disk (mathematics)

In geometry, a disk (also spelled disc) is the region in a plane bounded by a circle. A disk is said to be closed or open according to whether it contains the circle that constitutes its boundary.

Formulas

In Cartesian coordinates, the open disk of center and radius R is given by the formula

while the closed disk of the same center and radius is given by

The area of a closed or open disk of radius R is πR² (see area of a disk).

Properties

The disk has circular symmetry.

The open disk and the closed disk are not topologically equivalent (that is, they are not homeomorphic), as they have different topological properties from each other. For instance, every closed disk is compact whereas every open disk is not compact. However from the viewpoint of algebraic topology they share many properties: both of them are contractible and so are homotopy equivalent to a single point. This implies that their fundamental groups are trivial, and all homology groups are trivial except the 0th one, which is isomorphic to Z. The Euler characteristic of a point (and therefore also that of a closed or open disk) is 1.

DISC1

Disrupted in schizophrenia 1 is a protein that in humans is encoded by the DISC1 gene. In coordination with a wide array of interacting partners, DISC1 has been shown to participate in the regulation of cell proliferation, differentiation, migration, neuronal axon and dendrite outgrowth, mitochondrial transport, fission and/or fusion, and cell-to-cell adhesion. Several studies have shown that unregulated expression or altered protein structure of DISC1 may predispose individuals to the development of schizophrenia, clinical depression, bipolar disorder, and other psychiatric conditions. The cellular functions that are disrupted by permutations in DISC1, which lead to the development of these disorders, have yet to be clearly defined and are the subject of current ongoing research.

Discovery

In 1970, researchers from the University of Edinburgh performing cytogenetic research on a group of juvenile offenders in Scotland found an abnormal translocation in chromosome 1 of one of the boys, who also displayed characteristics of an affective psychological disorder. After this initial observation, the boy's family was studied and it was found that 34 out of 77 family members displayed the same translocation. According to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (or DSM-IV) criteria, sixteen of the 34 individuals identified as having the genetic mutation were diagnosed with psychiatric problems. In contrast, five of the 43 unaffected family members were identified to have psychological indispositions. The psychiatric illnesses observed in the family ranged from schizophrenia and major depression to bipolar disorder and adolescent conduct disorder (which the original research subject had). After studying this large Scottish family for four generations, in 2000, this gene was given the name "DISC1". The name was derived from the basis of the molecular nature of the mutation: the translocation directly disrupts the gene.
