+/- (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.

!!!

!!! is a dance-punk band that formed in Sacramento, California, in 1996 by lead singer Nic Offer. Its name is most commonly pronounced "Chk Chk Chk" ([/tʃk.tʃk.tʃk/]). Members of !!! came from other local bands such as The Yah Mos, Black Liquorice and Popesmashers. They are currently based in New York City, Sacramento, and Portland, Oregon. The band's sixth full-length album, As If, was released in October 2015.

Background and history

!!! is an American band formed in the summer of 1995 by the merger of part of the group Black Liquorice and Popesmashers. After a successful joint tour, these two teams decided to mix the disco-funk with more aggressive sounds and integrate the hardcore singer Nic Offer from the The Yah Mos. The band's name was inspired by the subtitles of the movie The Gods Must Be Crazy, in which the clicking sounds of the Bushmens' Khoisan language were represented as "!". However, as the bandmembers themselves say, !!! is pronounced by repeating thrice any monosyllabic sound. "Chk Chk Chk" is the most common pronunciation, which the URL of their official website and the title of their Myspace page suggest is the preferred pronunciation.

Separation (statistics)

In statistics, separation is a phenomenon associated with models for dichotomous or categorical outcomes, including logistic and probit regression. Separation occurs if the predictor (or a linear combination of some subset of the predictors) is associated with only one outcome value when the predictor is greater than some constant.

For example, if the predictor X is continuous, and the outcome y = 1 for all observed x > 2. If the outcome values are perfectly determined by the predictor (e.g., y = 0 when x ≤ 2) then the condition "complete separation" is said to obtain. If instead there is some overlap (e.g., y = 0 when x < 2, but y has observed values of 0 and 1 when x = 2) then "quasi-complete separation" obtains. A 2 × 2 table with an empty cell is an example of quasi-complete separation.

This observed form of the data is important because it causes problems with estimated regression coefficients. Loosely, a parameter in the model "wants" to be infinite, if complete separation is observed. If quasi-complete separation is the case, the likelihood is maximized at a very large but not infinite value for that parameter. Computer programs will often output an arbitrarily large parameter estimate with a very large standard error. Methods to fit these models include exact logistic regression and "Firth" logistic regression, a bias-reduction method based on a penalized likelihood.

Flocking (behavior)

Flocking behavior is the behavior exhibited when a group of birds, called a flock, are foraging or in flight. There are parallels with the shoaling behavior of fish, the swarming behavior of insects, and herd behavior of land animals.

Computer simulations and mathematical models which have been developed to emulate the flocking behaviors of birds can generally be applied also to the "flocking" behavior of other species. As a result, the term "flocking" is sometimes applied, in computer science, to species other than birds.

This article is about the modelling of flocking behavior. From the perspective of the mathematical modeller, "flocking" is the collective motion of a large number of self-propelled entities and is a collective animal behavior exhibited by many living beings such as birds, fish, bacteria, and insects. It is considered an emergent behavior arising from simple rules that are followed by individuals and does not involve any central coordination.

Flocking behavior was first simulated on a computer in 1987 by Craig Reynolds with his simulation program, Boids. This program simulates simple agents (boids) that are allowed to move according to a set of basic rules. The result is akin to a flock of birds, a school of fish, or a swarm of insects.

Separation (aeronautics)

In air traffic control, separation is the name for the concept of keeping an aircraft outside a minimum distance from another aircraft to reduce the risk of those aircraft colliding, as well as prevent accidents due to wake turbulence.

Air traffic controllers apply rules, known as separation minima to do this. Pairs of aircraft to which these rules have been successfully applied are said to be separated: the risk of these aircraft colliding is therefore remote. If separation is lost between two aircraft, they are said to be in a conflict.

When an aircraft passes behind or follows another aircraft, wake turbulence minima are applied due to the effect of the wingtip vortices of the preceding aircraft on the following aircraft. These minima vary depending on the relative size of the two aircraft. This is particularly acute on final approach with a smaller aircraft following larger aircraft.

Which aircraft need separating?

It is a common misconception that air traffic controllers keep all aircraft separated. Whether aircraft actually need separating depends upon the class of airspace in which the aircraft are flying, and the flight rules under which the pilot is operating the aircraft. As stated by the U.S. FAA, The pilot has the ultimate responsibility for ensuring appropriate separations and positioning of the aircraft in the terminal area to avoid the wake turbulence created by a preceding aircraft.
