Generic top-level domain

Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last label of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC 920.

The core group of generic top-level domains consists of the com, info, net, and org domains. In addition, the domains biz, name, and pro are also considered generic; however, these are designated as restricted, because registrations within them require proof of eligibility within the guidelines set for each.

Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains edu, gov, int, and mil are now considered sponsored top-level domains, much like the themed top-level domains (e.g., jobs). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term generic TLDs.

Dance (Disco Heat)

"Dance (Disco Heat)" is the title of a 1978 single by American disco singer Sylvester James, who performed using just his first name, Sylvester. The song became Sylvester's first Top 40 hit in the US, where it peaked at #19 on the Billboard Hot 100 chart in the fall of 1978; it also reached #29 on the UK Singles Chart. The song appears on his 1978 album, Step II.

A 12" single was released in 1978, with "Dance (Disco Heat)" as the A-side and "You Make Me Feel (Mighty Real)" as the B-side, and these two extended dance mixes proved to be very popular in the dance clubs at the time. The two songs held down the top spot on the Billboard Dance/Disco chart for six weeks in August and September of that year and helped to establish Sylvester's career as a noted disco and dance music performer, both in the U.S. and abroad.

Apex (headdress)

The apex was a cap worn by the flamines and Salii at Rome. The essential part of the apex, to which alone the name properly belonged, was a pointed piece of olive-wood, the base of which was surrounded with a lock of wool. This was worn on the top of the head, and was held there either by fillets only, or, as was more commonly the case, was also fastened by means of two strings or bands, which were called apicula (Festus, s.v.), or offendices (Festus, s.v.), though the latter word is also interpreted to mean a kind of button, by which the strings were fastened under the chin (cf. Serv. ad Virg. Aen. ii.683, viii.664, x.270).

The flamines were forbidden by law to go into public, or even into the open air without the apex (Gellius x.15), and hence we find the expression of alicui apicem dialem imponere used as equivalent to the appointment of a Flamen Dialis (Livy vi.41). Sulpicius was deprived of the priesthood, only because the apex fell from his head whilst he was sacrificing (Valerius Maximus i.1 §5).

Fictional character biography

Apex is one of sixteen teenagers kidnapped by Arcade who forces them to fight each other to the death in his latest version of Murderworld. She is part of the Braddock Academy group (consisting of Kid Briton, Anachronism, Bloodstone and Nara) which is joined by Death Locket despite death threats from Kid Briton and Nara. Death Locket started bonding with Apex as she introduces her to the rest of the Braddock Academy.

There is discord in the Braddock Academy's ranks as Anachronism and Kid Briton get into an argument. An earthquake then separates Bloodstone and Anachronism from Apex, Nara, Kid Briton, and Death Locket. Death Locket goes dormant as her cybernetics take over and she blasts Nara off a cliff and into the ocean. Kid Briton is enraged by this and tries to kill her until Apex orders him not to, revealing that she knew about his affair with Nara back at the Braddock Academy and that "we're here now and I'm done sharing."

Apex (radio band)

Apex was an experimental radio broadcasting system introduced in the United States in 1934 that used high frequencies between roughly 25 and 42 MHz and wideband AM modulation (as opposed to traditional AM broadcasting's narrowband modulation) to achieve high fidelity sound with less static and distortion than medium wave AM stations in the so-called standard broadcast band (then, 545-1505 kHz) experience. They were called "apex", "skyscraper" or "pinnacle" stations because of the height of the broadcast antennas used.

The Federal Communications Commission thought initially that very high frequency (VHF) radio waves would have a small, discrete range, and would allow two or more stations to broadcast on duplicate frequencies without interfering with each other. But later it was realized that during peaks in the 11-year sunspot cycle even VHF radio waves could reflect from the ionosphere, and Apex station signals could sometimes be heard on the other side of the planet. In October 1937, the FCC made public its allocation plan for VHF radio broadcasting: 75 channels with 40 kHz separation on 41.02 to 43.98 MHz for Apex stations and 16 channels in 30-40 MHz for relay stations. Twenty-five of the 75 channels were reallocated for educational use in 1938.
