Abstract: An online system presents a video from a third party system based on a video view value generate by the online system. Based on a target audience specification from the third party system, the online system selects a plurality of online system users as the audience of the video. The online system presents the video the selected users in a duration of time equal to a video presentation period received from the third party system. A play of the video by a selected user constitutes a historical view. The online system generates a video view value for the video based on historical views of the video by the selected users. The online system further applies the generated video view value for pacing delivery of the video by the online system.

Abstract: The present invention relates to a method for producing monocrystalline gallium containing nitride from a source material containing gallium in the environment of supercritical ammonia solvent with the addition of a mineralizer containing the element of Group I (IUPAC, 1989), wherein in an autoclave two temperature zones are generated, i.e. a dissolution zone with lower temperature containing the source material, and a crystallization zone located below it with higher temperature, containing at least one seed. At least two further components are introduced into the process environment, namely an oxygen getter in molar ratio to ammonia ranging from 0.0001 to 0.2, and an acceptor dopant in molar ratio to ammonia not higher than 0.1, said acceptor dopant being manganese, iron, vanadium or carbon, or a combination thereof. The invention also relates to a monocrystalline gallium containing nitride prepared by this method.

Abstract: The object of the invention is a method for obtaining monocrystalline gallium-containing nitride, from gallium-containing feedstock in the environment of supercritical ammonia-containing solvent with the addition of a mineraliser, containing an element of Group I (IUPAC, 1989), wherein, in an autoclave, two temperature zones are generated, i.e. a dissolution zone of lower temperature, containing feedstock, and, below it, a crystallisation zone of higher temperature, containing at least one seed, a dissolution process of the feedstock and a crystallisation process of the gallium-containing nitride on the at least one seed are carried out, characterised in that at least two additional components are introduced into the process environment, namely: a) an oxygen getter in a molar ratio to ammonia ranging from 0.0001 to 0.2, b) an acceptor dopant in a molar ratio to ammonia not higher than 0.001. The invention also includes monocrystalline gallium-containing nitride, obtained by this method.
