5-Hydroxyindoleacetic acid (5-HIAA) is the main metabolite of serotonin.The metabolic intermediate 5-hydroxyindoleacetaldehyde (5-HIAL) is formed from serotonin by monoamine oxidase (MAO) and then 5-HIAA is formed from 5-HIAL via aldehyde dehydrogenase (ALDH).
In January 1939 a specification was issued for a gun no heavier than 5.5 tons to replace the 6 inch 26 cwt howitzers in use with most medium batteries. For the desired range of 16,000 yards (15 km) ballistic studies recommended making a new calibre of 5.5 inches.
The 5-inch (127 mm)/54-caliber (Mk 45) lightweight gun is a U.S. naval artillery gun mount consisting of a 5 in (127 mm) L54 Mark 19 gun on the Mark 45 mount. [1] It was designed and built by United Defense, a company later acquired by BAE Systems Land & Armaments, which continued manufacture.
The Chinese armaments industry and the Chinese military were informed about the developments and experience that the US armed forces had during the Vietnam War with the M16 rifle and its 5.56×45mm M193 ammunition – not least because of the arms aid for Vietnam, as a result of which there was a high probability that captured US small arms and ammunition reached China.
Ninja is the most-followed channel on Twitch. [1]The live streaming social platform Twitch launched in 2011 and is an important platform for digital entertainment. [2] [3] The distribution of followers across all of the streamers on Twitch follows the power law, [4] and is a useful metric for assessing the popularity a streamer has on the platform.
β-Sulfur is a yellow solid with a monoclinic crystal form and is less dense than α-sulfur. It is unusual because it is only stable above 95.3 °C; below this temperature it converts to α-sulfur. β-Sulfur can be prepared by crystallising at 100 °C and cooling rapidly to slow down formation of α-sulfur.

For many years, sequence modelling and generation was done by using plain recurrent neural networks (RNNs). A well-cited early example was the Elman network (1990). In theory, the information from one token can propagate arbitrarily far down the sequence, but in practice the vanishing-gradient problem leaves the model's state at the end of a long sentence without precise, extractable ...
Polyacrylonitrile (PAN) is a synthetic, semicrystalline organic polymer resin, with the linear formula (CH 2 CHCN) n. [2] Almost all PAN resins are copolymers with acrylonitrile as the main monomer.
