Perceptron
In machine learning, the perceptron is an algorithm for supervised learning of binary classifiers.  A binary classifier is a function that can decide whether or not an input, represented by a vector of numbers, belongs to some specific class.  It is a type of linear classifier, i.e. a classification algorithm that makes its predictions based on a linear predictor function combining a set of weights with the feature vector.
2003 Cambodian general election
General elections were held in Cambodia on 27 July 2003 to elect members of the National Assembly. The elections were won by the ruling Cambodian People's Party, which won a majority of 73 seats in the 123-seat parliament.

Mount Shouplina
Mount Shouplina is an 8,531-foot-elevation (2,600-meter) mountain summit located 18 miles (29 km) north-northwest of Valdez in the U.S. state of Alaska. This remote glaciated mountain is set in the Chugach Mountains on land managed by Chugach National Forest. Precipitation runoff from the mountain drains south to Prince William Sound and north to Tazlina Lake → Tazlina River → Copper River. Topographic relief is significant as the summit rises 2,100 feet (640 m) above the East Branch Columbia Glacier in 0.4 mile (0.64 km). The first ascent of the summit was made in 1985 by John Weiland, Matt Kinney, and Bob Shelton. The mountain was named in 1959 by mountaineer Lawrence E. Nielsen and the toponym was officially adopted in 1965 by the U.S. Board on Geographic Names. The word "Shouplina" is a portmanteau blending the names of the Shoup Glacier and Tazlina Glacier which flow from this mountain's south and north slopes respectively.

Tazlina River
The Tazlina River is a 30-mile (48 km) tributary of the Copper River in the U.S. state of Alaska. Draining Tazlina Lake, it flows generally east to meet the larger river 7 miles (11 km) southeast of Glennallen.
Hyundai H-1
Hyundai H-1 is a nameplate of a van and pickup truck used by Hyundai Motor Company in European export markets for three related models:

Hyundai Starex, (called i800 in Europe, iLoad in Australia and H-200 in the Netherlands) a minibus/van

Hyundai Libero, a pickup truck

Minibus
A minibus, microbus, minicoach, or short bus is a passenger-carrying motor vehicle that is designed to carry more people than a multi-purpose vehicle or minivan, but fewer people than a full-size bus. In the United Kingdom, the word "minibus" is used to describe any full-sized passenger-carrying van or panel truck. Minibuses have a seating capacity of between 12 and 30. Larger minibuses may be called midibuses. Minibuses are typically front-engine step-in vehicles, although low floor minibuses are particularly common in Japan.
Cypionic acid
Cypionic acid, also known as cyclopentylpropionic acid, is an aliphatic carboxylic acid with the molecular formula C8H14O2. Its salts and esters are known as cypionates or cipionates.

The primary use of cypionic acid is in pharmaceutical formulations.  Cypionic acid is used to prepare ester prodrugs which have increased half-lives relative to the parent compound.  The lipophilicity of the cypionate group allows the prodrug to be sequestered in fat depots after intramuscular injection. The ester group is slowly hydrolyzed by metabolic enzymes, releasing steady doses of the active ingredient.  Examples include testosterone cypionate, estradiol cypionate, hydrocortisone cypionate, oxabolone cipionate, and mesterolone cypionate.

Carboxylic acid
In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO2H, sometimes as R−C(O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups. Carboxylic acids occur widely. Important examples include the amino acids and fatty acids. Deprotonation of a carboxylic acid gives a carboxylate anion.

341st Rifle Division (Soviet Union)
The 341st Rifle Division was first formed in September 1941, as a standard Red Army rifle division, at Stalingrad. It was a "sister" unit to the 335th Rifle Division, which was formed at about the same time and place and shared a very similar combat path in its first formation. It was assigned to the southern sector of the Soviet-German front during the winter counteroffensive, but was effectively destroyed during the German spring offensive that formed the Izium Pocket, and was soon disbanded. The division was formed again almost exactly two years later, this time in the Karelian Front, facing Finland, and saw only limited action in the Continuation War before being assigned to coastal defense duties during 1945. The 341st Rifle Division continued to serve well into the Cold War, eventually being re-designated and becoming a motorized rifle division.

JS Shiranui
JS Shiranui (DD-120) is the second ship of the Asahi-class destroyer of the Japanese Maritime Self-Defense Force. Her namesake came from the optical phenomenon called Shiranui, or "Phosphorescent Light".

Asahi-class destroyer
The Asahi class of destroyers is a class of warships of the Japan Maritime Self-Defense Force. The Asahi is largely based on the Akizuki-class destroyer; while the Akizuki-class specialized in anti-air warfare, the Asahi-class was designed to specialize in anti-submarine warfare. The design was initially designated "25DD", referring to a date on the Japanese calendar, specifically the 25th fiscal year of the Heisei period (2013), the year that procurement of the class began.

The lead ship, Asahi, is the third ship to hold the name after the Asahi-class destroyer escort lent from the United States Navy in 1955, and the Imperial Japanese battleship. The second ship of the class, Shiranui, is the third ship to hold its name after the Murakumo and Kagerō-class destroyers.

Agonist-antagonist
In pharmacology the term agonist-antagonist or mixed agonist/antagonist is used to refer to a drug which under some conditions behaves as an agonist (a substance that fully activates the receptor that it binds to) while under other conditions, behaves as an antagonist (a substance that binds to a receptor but does not activate and can block the activity of other agonists).

Types of mixed agonist/antagonist include receptor ligands that act as agonist for some receptor types and antagonist for others or agonist in some tissues while antagonist in others (also known as selective receptor modulators).

Mu-opioid receptor
The μ-opioid receptors (using the Greek letter mu, abbreviated MOR) are a class of opioid receptors with a high affinity for enkephalins and beta-endorphin, but a low affinity for dynorphins. They are also referred to as μ(mu)-opioid peptide (MOP) receptors. The prototypical μ-opioid receptor agonist is morphine, the primary psychoactive alkaloid in opium and for which the receptor was named, with mu being the first letter of Morpheus, the compound's namesake in the original Greek. It is an inhibitory G-protein coupled receptor that activates the Gi alpha subunit, inhibiting adenylate cyclase activity, lowering cAMP levels.

Purus Arch
The Purus Arch (Portuguese: Arco do Purus) is a basement high in Brazil that makes up the modern western boundary of the Amazon sedimentary basin. The Purus Arch is thought to be a former graben of Middle Proterozoic age that was inversed in the Late Proterozoic.

Although not obviously noticeable, today the Purus Arch crosses the Amazon River near the mouth of the Purus River. Following the water breach of the arch about 8–10 million years ago, the western (cf. Pebas Mega-wetland) and eastern parts of the present-day Amazon basin became a unified system, which played an important role in the biogeography of many aquatic organisms in the region.

Basement high
In geology, a basement high is a portion of the basement in a sedimentary basin that is higher than its surroundings. Commonly, basement highs are hidden by the sedimentary fill of the basin. Usually basement highs are elongated features of tectonic origin.
