Partisan Review
''Partisan Review'' (''PR'') was a small-circulation quarterly "little magazine" dealing with literature, politics, and cultural commentary published in New York City. The magazine was launched in 1934 by the Communist Party USA–affiliated John Reed Club of New York and was initially part of the Communist political orbit. Growing disaffection on the part of ''PR''s primary editors began to make itself felt, and the magazine abruptly suspended publication in the fall of 1936. When the magazine reemerged late in 1937, it came with additional editors and new writers who advanced a political line deeply critical of Joseph Stalin's Soviet Union. By the 1950s, the magazine had evolved towards a moderate social democratic and staunchly anti-Stalinist perspective and was generally supportive of American foreign policy. ''Partisan Review'' received covert funding from the Central Intelligence Agency (CIA) during the 1950s and 1960s as part of the agency's efforts to shape intellectual op ...

Penicillium Roqueforti
''Penicillium roqueforti'' is a common saprotrophic fungus in the genus ''Penicillium''. Widespread in nature, it can be isolated from soil, decaying organic matter, and plants. The major industrial use of this fungus is the production of blue cheeses, flavouring agents, antifungals, polysaccharides, proteases, and other enzymes. The fungus has been a constituent of Roquefort, Stilton, Danish blue, Cabrales, Gorgonzola, and other blue cheeses. Other blue cheeses are made with ''Penicillium glaucum''. Classification First described by American mycologist Charles Thom in 1906, ''P. roqueforti'' was initially a heterogeneous species of blue-green, sporulating fungi. They were grouped into different species based on phenotypic differences, but later combined into one species by Kenneth B. Raper and Thom (1949). The ''P. roqueforti'' group got a reclassification in 1996 due to molecular analysis of ribosomal DNA sequences. Formerly divided into two varieties―cheese-maki ...

Event (probability Theory)
In probability theory, an event is a set of outcomes of an experiment (a subset of the sample space) to which a probability is assigned. A single outcome may be an element of many different events, and different events in an experiment are usually not equally likely, since they may include very different groups of outcomes. An event consisting of only a single outcome is called an or an ; that is, it is a singleton set. An event S is said to if S contains the outcome x of the experiment (or trial) (that is, if x \in S). The probability (with respect to some probability measure) that an event S occurs is the probability that S contains the outcome x of an experiment (that is, it is the probability that x \in S). An event defines a complementary event, namely the complementary set (the event occurring), and together these define a Bernoulli trial: did the event occur or not? Typically, when the sample space is finite, any subset of the sample space is an event (that is, all e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
YPbPr
YPbPr or Y'PbPr, also written as , is a color space used in video electronics, in particular in reference to component video cables. YPBPR is gamma corrected YCBCR color space (it is not analog YUV that was used for analog TV, though component video is an analog interface); the two are numerically equivalent but YPBPR is designed for use in analog systems while YCBCR is intended for digital video. The EOTF (gamma correction) may be different from common sRGB EOTF and BT.1886 EOTF. Sync is carried on the Y channel and is a bi-level sync signal, however, in HD formats a tri-level sync is used and is typically carried on all channels. YPBPR is commonly referred to as ''component video'' by manufacturers; however, there are many types of component video, most of which are some form of RGB. Some video cards come with video-in video-out (VIVO) ports for connecting to component video devices. Technical details YPBPR is converted from the RGB video signal, which is split into th ...

Pull Request
In software development, distributed version control (also known as distributed revision control) is a form of version control in which the complete codebase, including its full history, is mirrored on every developer's computer. Compared to centralized version control, this enables automatic management branching and merging, speeds up most operations (except pushing and pulling), improves the ability to work offline, and does not rely on a single location for backups. Git, the world's most popular version control system, is a distributed version control system. In 2010, software development author Joel Spolsky described distributed version control systems as "possibly the biggest advance in software development technology in the astten years". Distributed vs. centralized Distributed version control systems (DVCS) use a peer-to-peer approach to version control, as opposed to the client–server approach of centralized systems. Distributed revision control synchronizes repositori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Reality
''Project Reality'' is a series of combined arms tactical first-person shooter video game modifications which aim to create a realistic combat environment where the core gameplay encourages teamwork and coordination. The original version, ''Project Reality: BF2'', was released in 2005 for ''Battlefield 2'', it is still being updated on a regular basis and became a stand-alone game in 2015. ''Project Reality'' for '' ARMA 2'' was released as a beta in 2011, development was later moved to '' ARMA 3'' in 2013. In September 2015 it was announced that the project had been suspended. ''Squad'', a commercial game built on Unreal Engine 4, is a spiritual sequel to ''Project Reality''. ''Project Reality: BF2'' Gameplay ''Project Reality'' features five game modes. Two of the most popular game modes are Advance and Secure (AAS) and Insurgency (INS). AAS involves capturing and holding control points, similar to the Conquest mode of Battlefield 2. However, in AAS, control points typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Performance Rating
The PR (Performance Rating, P-rating) system was a figure of merit developed by AMD, Cyrix, IBM Microelectronics and SGS-Thomson in the mid-1990s (Cyrix announced it in February 1996) as a method of comparing their x86 processors to those of rival Intel. The idea was to consider instructions per cycle (IPC) in addition to the clock speed, so that the processors become comparable with Intel's Pentium that had a higher clock speed with overall lower IPC. Branding The first use of the PR system was in 1995 year, when AMD used it to assert that their AMD 5x86 processor was as fast as a Pentium running at 75 MHz. The designation "P75" was added to the chip to denote this. The letters PR stood for "Performance Rating", but many people mistakenly thought it stood for "Pentium Rating", as the PR was often used to measure performance against Intel's Pentium processor. Later that year, Cyrix also adopted the PR system for its 6x86 and 6x86MX line of processors. These processors were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pagerank
PageRank (PR) is an algorithm used by Google Search to rank web pages in their search engine results. It is named after both the term "web page" and co-founder Larry Page. PageRank is a way of measuring the importance of website pages. According to Google: Currently, PageRank is not the only algorithm used by Google to order search results, but it is the first algorithm that was used by the company, and it is the best known. As of September 24, 2019, PageRank and all associated patents are expired. Description PageRank is a link analysis algorithm and it assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element ''E'' is referred to as the ''PageRank of E'' and denoted by PR(E). A PageRank results f ...

PR (complexity)
PR is the complexity class of all primitive recursive functions—or, equivalently, the set of all formal languages that can be decided in time bounded by such a function. This includes addition, multiplication, exponentiation, tetration, etc. The Ackermann function is an example of a function that is ''not'' primitive recursive, showing that PR is strictly contained in R (Cooper 2004:88). On the other hand, we can "enumerate" any recursively enumerable set (see also its complexity class RE) by a primitive-recursive function in the following sense: given an input (''M'', ''k''), where ''M'' is a Turing machine and ''k'' is an integer, if ''M'' halts within ''k'' steps then output ''M''; otherwise output nothing. Then the union of the outputs, over all possible inputs (''M'', ''k''), is exactly the set of ''M'' that halt. PR strictly contains ELEMENTARY Elementary may refer to: Arts, entertainment, and media Music * ''Elementary'' (Cindy Morgan album), 2001 * ''Ele ...

Progesterone Receptor
The progesterone receptor (PR), also known as NR3C3 or nuclear receptor subfamily 3, group C, member 3, is a protein found inside cells. It is activated by the steroid hormone progesterone. In humans, PR is encoded by a single ''PGR'' gene residing on chromosome 11q22, it has two isoforms, PR-A and PR-B, that differ in their molecular weight. The PR-B is the positive regulator of the effects of progesterone, while PR-A serve to antagonize the effects of PR-B. Mechanism Progesterone is necessary to induce the progesterone receptors. When no binding hormone is present the carboxyl terminal inhibits transcription. Binding to a hormone induces a structural change that removes the inhibitory action. Progesterone antagonists prevent the structural reconfiguration. After progesterone binds to the receptor, restructuring with dimerization follows and the complex enters the nucleus and binds to DNA. There transcription takes place, resulting in formation of messenger RNA that is tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
