Socket AM4
Socket AM4 is a PGA microprocessor socket used by AMD's central processing units (CPUs) built on the Zen (including Zen+, Zen 2 and Zen 3) and Excavator microarchitectures. ''AM4'' was launched in September 2016 and was designed to replace the sockets AM3+, FM2+ and FS1b as a single platform. It has 1331 pin slots and is the first from AMD to support DDR4 memory as well as achieve unified compatibility between high-end CPUs (previously using Socket AM3+) and AMD's lower-end APUs (on various other sockets). In 2017, AMD made a commitment to using the AM4 platform with socket 1331 until 2020. Features * Support for Zen (including Zen+, Zen 2 and Zen 3) based family of CPUs and APUs (Ryzen, Athlon), as well as for some A-Series APUs and Athlon X4 CPUs (Bristol Ridge based on the Excavator microarchitecture) * Supports PCIe 3.0 and PCIe 4.0 * Supports up to 4 modules of DDR4 RAM in dual-channel configuration Heatsink The AM4 socket specifies the 4 holes for fastening the ...

Amusement Vision
is a video game developer housed within the Japanese video game company Sega as part of its division. It is known for developing the games in the ''Yakuza'' series, which the studio is named after, since ''Yakuza 5''. The studio's origins can be traced back to Sega AM11 in 1998, which was renamed to R&D4 or AM4 in 1999. It was headed by Toshihiro Nagoshi who joined Sega AM2 in 1989 and been credited as the creator of the arcade titles ''Daytona USA'' and ''Virtua Striker.'' He requested his own development division during the development of ''Shenmue''. In 2000, AM4 was reestablished as Amusement Vision, where it was best known for ''Super Monkey Ball'' and ''F-Zero GX''. Several structural changes occurred in the years that followed. During a reorganization in 2003, the non-sports staff of Smilebit merged with Amusement Vision, and a year later Sega merged with Sammy to form Sega Sammy Holdings. Amusement Vision became New Entertainment R&D Dept. and the first ''Yakuza'' game w ...

Video Game Developer
A video game developer is a broad term for a software developer specializing in video game development – the process and related disciplines of creating video games. A game developer can range from one person who undertakes all tasks to a large business with employee responsibilities split between individual disciplines, such as Video game programmer, programmers, Video game design#Game designer, designers, Game art design#Video game artist, artists, etc. Most game development companies have video game publisher financial and usually marketing support. Self-funded developers are known as independent or indie developers and usually make indie games. A developer may specialize in specific Game engine, game engines or specific video game consoles (such as Nintendo's Nintendo Switch, Switch, Microsoft's Xbox Series X and Series S, Sony's PlayStation 5), or may develop for a number of systems (including personal computers and mobile devices). Video game developers specialize in certai ...

USS Swallow (AM-4)
USS ''Swallow'' (AM-4) was a U.S. Navy . ''Swallow'' was laid down at New York City on 18 March 1918 by the Todd Shipyard Corp.; launched on Independence Day 1918; sponsored by Miss Sara V. Brereton; and commissioned on 8 October 1918. She served until 19 February 1938, when she ran aground at Kanaga Island. History North Atlantic operations Following commissioning, ''Swallow'' underwent minor adjustments and prepared for foreign service. On 6 April 1919, she steamed out of Boston Harbor, bound for Inverness, Scotland. There she joined the Minesweeping Detachment of the Northern Barrage. For most of the remainder of 1919. ''Swallow'' swept mines from the North Sea Mine Barrage laid by the Allied and Associated Powers during World War I. West Coast operations The minesweeper returned to the United States late in 1919 and put into the navy yard at Charleston, South Carolina, for overhaul and repairs. Early in 1920, she sailed for the U.S. West Coast and then north to Breme ...

Ekspress-AM4
Ekspress-AM4 was a Russian communications satellite placed into the wrong orbit from a faulty Briz-M rocket stage. This satellite was to be part of the Ekspress series of geostationary communications satellites owned by Russian Satellite Communications Company (RSCC). Proposals were made to reposition the satellite to provide broadband services to Antarctica, but ultimately the decision was made to de-orbit the satellite. On 28 March 2012, the satellite splashed into the Pacific Ocean. Satellite description The total mass of the Ekspress-AM4 satellite was , and the satellite had 63 transponders. The onboard antennas were capable of broadcasting in the C-band, Ku-band, L-band, and Ka-band. The satellite's orbit was measured at 695 by 20239 km altitude, with an inclination orbit of 51.1°. Though the satellite was placed in the wrong orbit, there was no damage to the satellite, meaning that it became the subject of numerous reuse proposals. Launch The Ekspress-AM4 sa ...

AAA Battery
The AAA battery (or triple-A battery) is a standard size of dry cell Battery (electricity), battery. One or more AAA batteries are commonly used in low-drain portable electronic devices. A zinc–carbon battery in this size is designated by International Electrotechnical Commission, IEC as R03, by ANSI C18.1 as 24, by old Japanese Industrial Standards, JIS standard as UM-4, and by other manufacturer and national standard designations that vary depending on the cell chemistry. The size was first introduced by Eveready Battery Company, The American Ever Ready Company in 1911. An AAA battery is a single cell that measures in diameter and in length, including the positive terminal button, which is a minimum . The positive terminal has a maximum diameter of ; the flat negative terminal has a minimum diameter of . Alkaline battery, Alkaline AAA batteries weigh around , while primary lithium battery, lithium AAA batteries weigh about . Rechargeable Nickel–metal hydride battery, n ...

AM-2201
AM-2201 (1-(5-fluoropentyl)-3-(1-naphthoyl)indole) is a recreational designer drug that acts as a potent but nonselective full agonist for the cannabinoid receptor. It is part of the AM series of cannabinoids discovered by Alexandros Makriyannis at Northeastern University. Hazards Convulsions have been reported including at doses as low as 10 mg. Pharmacology AM-2201 is a full agonist for cannabinoid receptors. Affinities are: with a ''K''i of 1.0 nM at CB1 and 2.6 nM at CB2. The 4-methyl functional analog MAM-2201 probably has similar affinities. AM-2201 has an EC50 of 38 nM for human CB1 receptors, and 58 nM for human CB2 receptors. AM-2201 produces bradycardia and hypothermia in rats at doses of 0.3–3 mg/kg, comparable to the potency of JWH-018 in rats, suggesting potent cannabinoid-like activity. Pharmacokinetics AM-2201 metabolism differs only slightly from that of JWH-018. AM-2201 ''N''-dealkylation produces fluoropentane instead of p ...
