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. Rennsport Reunion I The first Porsche Rennsport Reunion event was held at Lime Rock Park, Connecticut in 2001. Rennsport Reunion II The Porsche Rennsport Reunion II was hel ...
