"Yellow Flicker Beat" is a song by New Zealand singer Lorde.
 Written by Lorde and Joel Little and produced by Little and Paul Epworth, the song was released on 29 September 2014 as the lead single from the soundtrack for "" by Republic Records.
 "Yellow Flicker Beat", which features an electronic production, is characterised as an art pop and electropop song.
 Its style was compared to that of Lorde's earlier releases such as her song "Biting Down" from "The Love Club EP" (2013) and her debut studio album, "Pure Heroine" (2013).
 The lyrics of the track refer to the rise of "The Hunger Games"' heroine Katniss Everdeen.
The campo flicker ("Colaptes campestris") is a species of bird in the woodpecker family.
 It is found in a wide range of open and semi-open habitats in eastern Brazil, Bolivia, Paraguay, Uruguay and north-eastern Argentina, with isolated populations in Amapá and southern Suriname.
 Though it frequently can be seen in trees or bushes, it is among the very few woodpeckers that spends a significant portion of its life on the ground.
 It breeds in holes in trees, termite mounds or earth banks.
 It is generally common, and therefore considered to be of least concern by IUCN.
 The southern population has a white (not black) throat, and is sometimes considered a separate species, the pampas flicker ("Colaptes campestroides").
The Andean flicker ("Colaptes rupicola") is a South American species of woodpecker.
 It is found in grassland, shrubland and "Polylepis" woodland at altitudes of 2000 - in the Puna ecoregion.
 Together with the campo flicker and ground woodpecker, it is one of the few largely terrestrial woodpeckers.
David Charles Hahn (October 30, 1976 – September 27, 2016), sometimes called the Radioactive Boy Scout or the Nuclear Boy Scout, was an American man who in 1994, at age 17, attempted to build a homemade breeder reactor.
 A scout in the Boy Scouts of America, Hahn conducted his experiments in secret in a backyard shed at his mother's house in Commerce Township, Michigan.
 While his reactor never reached critical mass, Hahn attracted the attention of local police when he was stopped on another matter and they found material in his vehicle that troubled them, and he warned that it was radioactive.
 His mother's property was cleaned up by the Environmental Protection Agency ten months later as a Superfund cleanup site.
 Hahn attained Eagle Scout rank shortly after his lab was dismantled.
The Love Club EP is the debut extended play (EP) by New Zealand singer Lorde.
 At the age of 12, she was discovered by Universal Music Group scout Scott MacLachlan, and began writing songs.
 In December 2011, MacLachlan paired Lorde with producer Joel Little, and within three weeks, the pair had co-written and produced all 5 songs on the EP.
 In November 2012, Lorde self-released the EP for free download via SoundCloud.
 On 8 March 2013 the record was commercially released by Universal Music Group and Virgin Records.
"Team" is a song by New Zealand singer Lorde, taken from her debut studio album, "Pure Heroine" (2013).
 The song was released on 13 September 2013 as the album's third single in Australia and New Zealand by Universal Music New Zealand, and the second in the United States and the United Kingdom by Lava and Republic Records.
 The track was written by Lorde and Joel Little and produced by Little, with additional production from Lorde herself.
 "Team" is a hybrid of alternative pop and electro-hop featuring synthesiser, bass and snare drum instrumentation over a handclap-based beat.
 Lyrically, the track is a "tribute to her friends and country".
Steady State Topography (abbreviated SST) is a methodology for observing and measuring human brain activity that was first described by Richard Silberstein and co-workers in 1990.
 While SST has been principally used as a cognitive neuroscience research methodology it has also found commercial application in the field of neuromarketing and consumer neuroscience in such areas as brand communication, media research and entertainment.
 In a typical SST study, brain electrical activity (electroencephalogram or EEG) is recorded while participants view audio visual material and/or perform a psychological task.
 Simultaneously, a dim sinusoidal visual flicker is presented in the visual periphery.
 The sinusoidal flicker elicits an oscillatory brain electrical response known as the Steady State Visually Evoked Potential (SSVEP).
 Task related changes in brain activity in the vicinity of the recording site are then determined from SSVEP measurements at that site.
 One of the most important features of the SST methodology is the ability to measure variations in the delay (latency) between the stimulus and the SSVEP response over extended periods of time.
 This offers a unique window into brain function based on neural processing speed as opposed to the more common EEG amplitude indicators of brain activity.
The gilded flicker ("Colaptes chrysoides") is a large-sized woodpecker (mean length of 29 cm ) of the Sonoran, Yuma, and eastern Colorado Desert regions of the southwestern United States and northwestern Mexico including all of the Baja Peninsula except the extreme northwestern region.
 Golden yellow underwings distinguish the gilded flicker from the northern flicker found within the same region, which have red underwings.
Audre Lorde ( ; born Audrey Geraldine Lorde; February 18, 1934 – November 17, 1992) was a writer, feminist, womanist, librarian, and civil rights activist.
 As a poet, she is best known for technical mastery and emotional expression, as well as her poems that express anger and outrage at civil and social injustices she observed throughout her life.
 Her poems and prose largely deal with issues related to civil rights, feminism, and the exploration of black female identity.
 In relation to non-intersectional feminism in the United States, Lorde famously said, "Those of us who stand outside the circle of this society's definition of acceptable women; those of us who have been forged in the crucibles of difference -- those of us who are poor, who are lesbians, who are Black, who are older -- know that survival is not an academic skill.
 It is learning how to take our differences and make them strengths.
 For the master's tools will never dismantle the master's house.
 They may allow us temporarily to beat him at his own game, but they will never enable us to bring about genuine change.
 And this fact is only threatening to those women who still define the master's house as their only source of support."
The pampas flicker ("Colaptes campestris campestroides") is a woodpecker in the family Picidae, it is usually considered conspecific with the campo flicker ("Colaptes campestris"), but some authorities consider it a distinct species.
 It is found in south-eastern Brazil, central and southern Paraguay, Uruguay and north-western and western Argentina.
