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 ...

Pathogenesis-related
Pathogenesis-related (PR) proteins are proteins produced in plants in the event of a pathogen attack. They are induced as part of systemic acquired resistance. Infections activate genes that produce PR proteins. Some of these proteins are antimicrobial, attacking molecules in the cell wall of a bacterium or fungus. Others may function as signals that spread “news” of the infection to nearby cells. Infections also stimulate the cross-linking of molecules in the cell wall and the deposition of lignin, responses that set up a local barricade that slows spread of the pathogen to other parts of the plant. Salicylic acid plays a role in the resistance to pathogens by inducing the production of pathogenesis-related proteins. Many proteins found in wine are grape pathogen-related proteins. Those include thaumatin-like proteins and chitinases. Many pathogenesis-related protein families also coincide with groups of human allergens, even though the allergy may have nothing to do with ...

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 (Unix)
pr is a command on various operating systems that is used to paginate or columnate computer files for printing. It can also be used to compare two files side by side, as an alternative to diff. It is a required program in a POSIX-compliant environment and has been implemented by GNU as part of the GNU Core Utilities. The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities. It is also available in the OS-9 OS-9 is a family of real-time, process-based, multitasking, multi-user operating systems, developed in the 1980s, originally by Microware Systems Corporation for the Motorola 6809 microprocessor.

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] |
PR-104
PR-104 is a drug from the class of hypoxia-activated prodrugs (HAPs), which is being researched as a potential anti-cancer therapeutic agent. It is a phosphate ester “pre-prodrug” that is rapidly converted to the HAP PR-104A in the body. PR-104A is in turn metabolised to reactive nitrogen mustard DNA crosslinking agents in hypoxic tissues such as found in solid tumours. Following initial clinical studies, it was discovered that PR-104A is also activated by the enzyme AKR1C3 Aldo-keto reductase family 1 member C3 (AKR1C3), also known as 17β-hydroxysteroid dehydrogenase type 5 (17β-HSD5, HSD17B5) is a key steroidogenic enzyme that in humans is encoded by the ''AKR1C3'' gene. Function This gene encodes a member of t ..., independently of hypoxia. Hypoxia in the bone marrow of patients with leukaemia, and high activity of AKR1C3 in some leukaemia subtypes has led to interest in clinical trials of PR-104 in relapsed refractory acute leukaemias.

PR Interval
In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration. The PR interval is sometimes termed the PQ interval. Interpretation Variations in the PQ interval can be associated with certain medical conditions: * Duration ** A long PR interval (of over 200 ms) indicates a slowing of conduction between the atria and ventricles, usually due to slow conduction through the atrioventricular node (AV node). This is known as first degree heart block. Prolongation can be associated with fibrosis of the AV node, high vagal tone, medications that slow the AV node such as beta-blockers, hypokalemia, acute rheumatic fever, or carditis associated with Lyme disease. ** A short PR interval (of less than 120ms) may be associated with a Pre-excitation syndromes ...
