Parietal Reach Region
The parietal reach region (PRR) is a region within the posterior parietal cortex of the macaque brain that is stimulated through reaching for an object. The PRR was initially proposed by Andersen Andersen () is a Danish- Norwegian patronymic surname meaning "son of Anders" (itself derived from the Greek name " Ανδρέας/Andreas", cf. English Andrew). It is the fifth most common surname in Denmark, shared by about 3.2% of the populati ... and Buneo, but they just generally explored the idea as postural modulations. Dr. Steven Chang went further in depth by showing the receptive fields of PRR neurons are multiplicatively stimulated through the combination of initial gaze position and initial hand position. This multiplicative stimulation is known as gain-field encoding. The parietal reach region uses gain-field encoding to calculate the amount of hand displacement needed to reach for an object. A recent study shows that neurons in PRR encodes not only the planned physica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pattern Recognition Receptor
Pattern recognition receptors (PRRs) play a crucial role in the proper function of the innate immune system. PRRs are germline-encoded host sensors, which detect molecules typical for the pathogens. They are proteins expressed mainly by cells of the innate immune system, such as dendritic cells, macrophages, monocytes, neutrophils, as well as by epithelial cells, to identify two classes of molecules: pathogen-associated molecular patterns (PAMPs), which are associated with microbial pathogens, and damage-associated molecular patterns (DAMPs), which are associated with components of host's cells that are released during cell damage or death. They are also called primitive pattern recognition receptors because they evolved before other parts of the immune system, particularly before adaptive immunity. PRRs also mediate the initiation of antigen-specific adaptive immune response and release of inflammatory cytokines. PRRs are regulated through a variety of pathways ensure optimal im ...

Pennsylvania Railroad
The Pennsylvania Railroad ( reporting mark PRR), legal name as the Pennsylvania Railroad Company, also known as the "Pennsy," was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. At its peak in 1882, the Pennsylvania Railroad was the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Over its existence, Pennsylvania Railroad acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated of rail line;This mileage includes companies independently operated. PRR miles of all tracks, which includes first (or main), second, third, fourth, and sidings, totalled 28,040.49 at the end of 1926. in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, Topeka & Santa Fe railroads. Its only formidable rival was the New York Centra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pichi Richi Railway
Pichi Richi Railway is a narrow-gauge heritage railway in the southern Flinders Ranges of South Australia between Quorn and Port Augusta. For much of its length the line lies in the picturesque Pichi Richi Pass, where the line was completed in 1879 as work proceeded north to build a railway to the "Red Centre" of Australia – the Central Australia Railway. The Commonwealth Railways ran trains through the pass until 1970, when it ceased services. There were proposals to demolish the line including the bridges and dry stone walls, but the Quorn Progress Association recognised their heritage value and significance. Lobbying by local and distant supporters reached Mr. Keith Smith, Commissioner of the Commonwealth Railways. On 22 July 1973, the not-for-profit Pichi Richi Railway Preservation Society Inc. was incorporated, initially to ensure conservation of the 1878 dry stone walls and the bridges in the Pichi Richi Pass. It became evident that the prospect of operating heritag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Right-wing Populism
Right-wing populism, also called national populism and right populism, is a political ideology that combines right-wing politics with populist rhetoric and themes. Its rhetoric employs anti- elitist sentiments, opposition to the Establishment, and speaking to or for the common people. Recurring themes of right-wing populists include neo-nationalism, social conservatism, economic nationalism, and fiscal conservatism. Frequently, they aim to defend a national culture, identity, and economy against attacks by outsiders. Right-wing populism has associations with authoritarianism, while some far-right populists draw comparisons to fascism. Right-wing populism in the Western world is sometimes associated with ideologies such as anti-environmentalism, anti-globalization, nativism, and protectionism. In Europe, the term is often used to describe groups, politicians, and political parties generally known for their opposition to immigration, especially from the Muslim world, ...

Princes Risborough Railway Station
Princes Risborough railway station is a stop on the Chiltern Main Line, serving the market town of Princes Risborough in Buckinghamshire, England. It is managed by Chiltern Railways, which operates all services that stop here. History At one time, there were four different railway routes from the northern end of Princes Risborough station, although there has only ever been one to the south. The first railway to reach the town was the Wycombe Railway, which opened its extension from High Wycombe as far as on 1 August 1862. Mitchell & Smith, April 2003, ''Historical Background'' There were three intermediate stations on this section: West Wycombe, Princes Risborough and . The cost of construction of the station building was £1,104 9s 5d and additional general costs were £824 8s 0d. The station building as built was a typical Wycombe railway design with an open porch at the right hand end on the platform elevation, the design was the same as West Wycombe, Bledlow and Wheatl ...

Production Rule Representation
The Production Rule Representation (PRR) is a proposed standard of the Object Management Group (OMG) that aims to define a vendor-neutral model for representing production rules within the Unified Modeling Language (UML), specifically for use in forward-chaining rule engines. History The OMG set up a Business Rules Working Group in 2002 as the first standards body to recognize the importance of the "Business Rules Approach". It issued 2 main RFPs in 2003 – a standard for modeling production rules (PRR), and a standard for modeling business rules as business documentation (BSBR, now SBVR). PRR was mostly defined by and for vendors of Business Rule Engines (BREs) (sometimes termed Business Rules Engine(s), like in Wikipedia). Contributors have included all the major BRE vendors, members of RuleML, and leading UML vendors. Evolution # The PRR RFP originally suggested that PRR use a combination of UML OCL and Action Semantics for rule conditions and actions. However, expec ...

Proportional Reporting Ratio
The proportional reporting ratio (PRR) is a statistic that is used to summarize the extent to which a particular adverse event is reported for individuals taking a specific drug A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. Consumption of drugs can be via insufflation (medicine), inhalation, drug i ..., compared to the frequency at which the same adverse event is reported for patients taking some other drug (or who are taking any drug in a specified class of drugs). The PRR will typically be calculated using a surveillance database in which reports of adverse events from a variety of drugs are recorded. A PRR greater than 1 suggests that the adverse event is more commonly reported for individuals taking the drug of interest, relative to the comparison drugs. This could indicate that the adverse event is caused by the drug of interest and therefore a "s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudo-response Regulator
Pseudo-response regulator (PRR) refers to a group of genes that regulate the circadian oscillator in plants. There are four primary PRR proteins (PRR9, PRR7, PRR5 and TOC1/PRR1) that perform the majority of interactions with other proteins within the circadian oscillator, and another (PRR3) that has limited function. These genes are all paralogs of each other, and all repress the transcription of Circadian Clock Associated 1 ( CCA1) and Late Elongated Hypocotyl (LHY) at various times throughout the day. The expression of PRR9, PRR7, PRR5 and TOC1/PRR1 peak around morning, mid-day, afternoon and evening, respectively. As a group, these genes are one part of the three-part repressilator system that governs the biological clock in plants. Discovery Multiple labs identified the PRR genes as parts of the circadian clock in the 1990s. In 2000, Akinori Matsushika, Seiya Makino, Masaya Kojima, and Takeshi Mizuno were the first to understand PRR genes as pseudo-response repressor genes ...
