Alien (law)
In law, an alien is a person who resides within the borders of a country and is not a national of that country, though definitions and terminology differs to some degree.
Etymology
The term "alien" is derived from the Latin alienus, meaning stranger, foreign.
Categories
Different countries use varying terms for "aliens" including:
- a nonresident alien is a non-citizen who is visiting a country, for example as a tourist, on business, entertainers, sportspeople or in the country to receive medical treatment.
- a resident alien is a non-citizen who has temporary resident status in a country.
Alien (creature in Alien franchise)
The "Alien" (also referred to as a "Xenomorph") is a fictional endoparasitoid extraterrestrial arthropodal species that is the eponymous antagonist of the Alien film series. The species made its debut in the film Alien (1979), and reappeared in the sequels Aliens (1986), Alien 3 (1992), and Alien: Resurrection (1997), as well as the crossover franchise Alien vs. Predator (2004) and Aliens vs. Predator: Requiem (2007). A similar creature of a slightly different design also briefly appears in the Ridley Scott film Prometheus (2012). In addition, the Alien appears in various literature and video game spin-offs from the franchises.
Unlike many other extraterrestrial races in science fiction, the Aliens lack a technological civilization and are predatory creatures with no higher goals than the propagation of their species and the ultimate destruction of lifeforms that could pose a threat to them. Like wasps or termites, Aliens are eusocial, with a single fertile queen breeding a caste of warriors. The Aliens' biological life cycle involves traumatic implantation of endoparasitoid larvae inside living hosts; these larvae erupt from the host's chest or intestines after a short incubation period, rapidly mature from juvenile into adulthood, and seek out more hosts for implantation.
Extraterrestrial life
Extraterrestrial life is life that does not originate from Earth. It is also called alien life, or, if it is a sentient and/or relatively complex individual, an "extraterrestrial" or "alien" (or, to avoid confusion with the legal sense of "alien", a "space alien"). These as-yet-hypothetical life forms range from simple bacteria-like organisms to beings with civilizations far more advanced than humanity. Although many scientists expect extraterrestrial life to exist, there is no unambiguous evidence for its existence so far.
The science of extraterrestrial life is known as exobiology. The science of astrobiology also considers life on Earth as well, and in the broader astronomical context. Meteorites that have fallen to Earth have sometimes been examined for signs of microscopic extraterrestrial life. In 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia, when the young Earth was about 400 million years old. According to one of the researchers, "If life arose relatively quickly on Earth ... then it could be common in the universe."
Presence (DC Comics)
The Presence is a fictional representation of God, and is a character in comic books published by DC Comics. The character debuted in More Fun Comics #52 (February 1940), and was created by Jerry Siegel and Bernard Baily.
Publication history
The presence first appears in More Fun Comics #52 as The Voice, the disembodied "Voice of the Presence" who empowers Jim Corrigan as the Spectre. It was created in this story by Jerry Siegel and Bernard Baily.
DC Comics
The religious cosmology of the DC Universe is complex with many pantheons of deities co-existing alongside each other. It involves elements from multiple religions, mythologies, and modern created concepts such as the Endless. It is not always clear how the Abrahamic God fits into this — for example, one particular Wonder Woman storyline by Eric Luke featured the Greek Titans fighting Judeo-Christian angels and Hindu Gods. According to writer Greg Rucka in an interview about his Final Crisis: Revelations miniseries, "The sort of unspoken rule in the DCU is that God sits above all others."
Presence (Marvel Comics)
Sergei Krylov is a fictional character in the Marvel Comics Universe.
Fictional character biography
As a younger man, Sergei was a Russian nuclear physicist born in Minsk, Soviet Union. His twin children, Nikolai Krylenko and Laynia Petrovna were taken from birth by the Soviet government to be trained as soldiers, after their mutant natures manifested.
Sergei eventually became one of the most influential men behind the scenes of the Soviet government. However, despite being a scientific genius, he was also quite mad. He caused a Chernobyl-like nuclear disaster in the "Forbidden Zone" using cobalt radiation baths and a nuclear blast, which transformed Tania Belinsky into his super-powered thrall as the second Red Guardian. The nuclear energy transformed Sergei into a superhuman being as well, and he could now generate nuclear energy within his own body for various uses. Sergi began calling himself "The Presence". The Presence and Red Guardian battled the Defenders when they came to find her. The Presence left when she regained her free will and spurned him. Soon after, the Presence battled a giant mutated amoeba in the "Forbidden Zone", and was then reunited and reconciled with Red Guardian.
Presence (amplification)
In an amplifier, a presence control boosts the upper mid-range frequencies to make the sounds of voices and instruments with similar tonal ranges seem more "present".
On television production studio's sound desk, there can be several presence controls, for several different, switchable, frequencies. There is a limit to the flexibility of such controls, and they are sometimes insufficient. If the degree of mis-match between microphones is great, simply increasing presence is not enough, and instead a sound engineer will use a graphic equalizer, sometimes several, each connected to an individual sound channel.
Presence controls can also be found on electric guitar amplifiers. The first presence control on a Fender amplifier, for example, appeared in 1954 on the Twin. In 1955 it appeared on the 1/15 Pro-Amp, the 3/10 Bandmaster, the 2/10 Super, and the 4/10 Bassman. The original Fender presence control acted upon the amplifier's negative-feedback loop. As the level of "presence" was increased, so more and more of the higher frequencies in the negative-feedback loop were dumped to ground, leaving the low and mid-range frequencies. Increasing the presence resulted in there being less and less negative feedback on high frequencies. The effect varied according to amplitude.
