Residual Kid is an American rock band from Austin, Texas formed in 2009.
 The group consists of Deven Ivy (vocals, guitar), Ben Redman (drums), and Max Redman (bass guitar).
 They have released three EPs: "Box" in 2011, which was recorded with an earlier lineup, "Faces", featuring the current lineup, in 2012, and "Salsa" in 2016.
In mathematics, more specifically in topology, the equivariant stable homotopy theory is a subfield of equivariant topology that studies a spectrum with group action instead of a space with group action, as in stable homotopy theory.
 The field has become more active recently because of its connection to algebraic K-theory.
Faces is an EP by American alternative rock band "Residual Kid", which was released in October 2012.
 It was produced by Grammy-nominated Chris "Frenchie" Smith.
This Century was an American pop rock band from Phoenix, Arizona.
 The band consisted of members Joel Kanitz, Ryan Gose, and Sean Silverman.
 In February 2014, Alex Silverman announced his departure from the group.
 In May 2015 the band announced that following the release of their next album (released June 2, 2015) they would be playing a final tour, retiring the band so members could "pursue each our passions and musical projects".
Ryan Michael Gentles (born November 28, 1977) is the manager of the New York City-based band, The Strokes and the Chief Executive Officer of Wiz Kid Management.
 Before meeting the Strokes, he was the vocalist and guitarist in two bands, Timmsie's First Time, which broke up in 1995 and The Selzers, which broke up in 2000.
 Matthew Romano, The Strokes' drum technician and back-up drummer, was also in both bands, playing drums.
 Recently Ryan has stated that being part of the Selzers "was not exactly a proud moment" for him.
In the Fishtank is an ongoing project of Konkurrent, an independent music distributor in the Netherlands.
 In this project, Konkurrent invites one or two bands to record and gives them two days studio time.
 The first four albums were recorded by individual bands, but eight of the last ten releases were the result of two bands (three in one case) teaming up to record.
 The Ex is so far the only band to appear on more than one album in the series.
Treat is a split cassette shared between by Dutch punk band The Ex and Scottish ex-pat tour mates Dog Faced Hermans.
 The album was recorded live while the two bands toured Europe together and was released only on cassette in 1990.
 That year the two bands also collaborated on the single "Lied der Steinklopfer" ("Stonestamper's Song") released under the name Ex Faced Hermans, as well as sharing live sound engineer Gert-Jan, credited as a full member of the Dog Faced Hermans who continued to tour with The Ex for more than a decade.
Salsa is an EP by American alternative rock band "Residual Kid", which was released April 8, 2016.
 It was produced by Grammy-nominated Chris "Frenchie" Smith.
 To celebrate the release, the band held an EP release show at The Hi-Dive in Denver, Colorado.
 The song "Scentless Princess" was released as the lead single from the EP, with a video directed by Joshua Logan and Michael Anthony Gibson.
 A second music video was released later for the song "Chill."
North American television frequencies are different for over-the-air (also called terrestrial) and cable television systems.
 Over-the-air television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 83 and occupies frequencies between 470 and 890 MHz.
 These bands are different enough in frequency that they often require separate antennas to receive (although many antennas cover both VHF and UHF), and separate tuning controls on the television set.
 The VHF band is further divided into two frequency ranges: VHF low band (Band I) between 54 and 88 MHz, containing channels 2 through 6, and VHF high band (Band III) between 174 and 216 MHz, containing channels 7 through 13.
 The wide spacing between these frequency bands is responsible for the complicated design of rooftop TV antennas.
 The UHF band has higher noise and greater attenuation, so higher gain antennas are often required for UHF.
In the Fishtank 12 is an EP released in 2005 and recorded by the Boston-based band Karate.
 Part of the In the Fishtank series released by Dutch music distributor Konkurrent, it would prove to be Karate's last studio recording.
 Karate broke up later that year due to frontman Geoff Farina's transition into acoustic music on account of suffering from tinnitus.
 The EP consists exclusively of covers, mostly of songs by seminal 1980s hardcore band Minutemen.
 This particular recording was the only release in the series during the 21st century to feature a single band; most of the latter releases in the series featured two bands (or in the case of "In the Fishtank 9", three bands).
