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 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 Gain field encoding is a hypothesis about the internal storage and processing of limb motion in the brain. In the motor areas of the brain, there are neurons which collectively have the ability to store information regarding both limb positioning .... 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 and 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. The microbe-specific molecules that are recognized by a given PRR are called p ...

Pennsylvania Railroad
The Pennsylvania Railroad (reporting mark PRR), legal name 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. It was named for the commonwealth in which it was established. By 1882, Pennsylvania Railroad had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Its budget was second only to the U.S. government. Over the years, it 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, T ...

Personal Role Radio
The H4855 Personal Role Radio (PRR) is a small UHF transmitter-receiver issued to the British Armed Forces. It is used by the British Army, Royal Marines, Royal Navy and the Royal Air Force Regiment. The radio has a range of 500 meters, weighs 1.5 kilograms, has 256 different radio channels and a battery life of 20 hours continuous use. It allows users to communicate over short distances. Effective even through thick cover or the walls of buildings, PRR is issued to every member of an eight-strong infantry section. It is manufactured by Marconi-Selenia Communications (then Selenia Communications, Selex ES until 2015, now Leonardo new name of Finmeccanica since 2016). The PRR was originally part of the wider Bowman radio project but was hived off in October 1999 for more rapid implementation, and the first of 45,000 units formally entered service in early 2002. Operating in the 2.4 GHz band, PRR has integrated encryption but does not intercommunicate with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Right-wing Populism
Right-wing populism, also called national populism and right-wing nationalism, is a political ideology that combines right-wing politics and 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, and economic nationalism. Frequently, they aim to defend a national culture, identity, and economy against perceived attacks by outsiders. Right-wing populism in the Western world is generally 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, and for Euroscepticism. Right-wing populists may support expanding the welfare state, but only for those they deem fit to receive i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche Rennsport Reunion
The Porsche Rennsport Reunion is an automotive event and the world's largest meeting of classic Porsche racing cars and their drivers. Porsche has been organising the Rennsport Reunion since 2001 to honour its Porsche in motorsport, own motorsport tradition. The event has been conceived by the former British racing driver Brian Redman and former Porsche Cars North America’s press spokesperson Bob Carlson. History Rennsport Reunion is an event hosted since 2001 every 3 to 5 years in the United States. After the first three events were held on the East Coast of the United States, east coast of the US, two events at Daytona International Speedway in Daytona Beach, Florida in 2004 and 2007 followed, before the event moved for Rennsport Reunion IV to the West Coast of the United States, west coast in 2011.

Princes Risborough Railway Station
Princes Risborough station is a railway station on the Chiltern Main Line that serves the town of Princes Risborough in Buckinghamshire, England. It is operated by Chiltern Railways. History At one period 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 Princes Risborough 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 £1104 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 Wheatley, and also on the original part of ...

Production Rule Representation
The Production Rule Representation (PRR) is a proposed standard of the Object Management Group (OMG) to provide a vendor-neutral rule-model representation in UML for production rules as used 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, expecting modellers to learn 2 relatively obscure UML la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 "side effect", although a PRR exceeding 1 could also reflect sampling variation in the data, reporting errors, biased reporting, multiple reports of the same case or the same patient, or a number of other causes. The PRR is defined as the ratio between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudo-response Regulator
Pseudo-response regulator (PRR) refers to a group of genes that are important in the plant circadian oscillator. 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 gene ...

Pure Reason Revolution
Pure Reason Revolution (PRR) is a British rock group formed at the University of Westminster in 2003. Their music incorporates elements of progressive rock and electronic. Their music has been variously described as 'Astral Folk' and 'Progressive rock'. Members have a shared appreciation for the work of bands such as Pink Floyd, Porcupine Tree, Nirvana, Justice, Kraftwerk and Fleetwood Mac. History The Sunset Sound Pure Reason Revolution began life as a Reading group named The Sunset Sound, which featured the Courtney brothers, Chloë Alper and, for a short while, Jim Dobson. The Courtney brothers had previously played with pop punk guitar band Gel, which was scouted and signed by Seymour Stein, the founder of Sire. Alper used to front Period Pains, who scored a hit with an anti-Spice Girls song in 1997. The band was completed by Tom Leathes (vocals, guitar) and Bob Cooper (bass guitar). Debut single "Moving" picked up radio airplay on BBC Radio 1 (where the band was champion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
