Haplogroup L0 (mtDNA)
Haplogroup L0 is a human mitochondrial DNA (mtDNA) haplogroup. Origin L0 is one of two branches from the most recent common ancestor (MRCA) for the shared human maternal lineage. The haplogroup consists of five main branches (L0a, L0b, L0d, L0f, L0k). Four of them were originally classified into L1 subclades, L1a, L1d, L1f and L1k. In 2014, ancient DNA analysis of a 2,330 year old male forager's skeleton in Southern Africa found that the specimen belonged to the L0d2c1c mtDNA subclade. This maternal haplogroup is today most closely associated with the Ju, a subgroup of the indigenous San people, which points to population continuity in the region. In 2016, a Late Iron Age desiccated mummy from the Tuli region in northern Botswana was also found to belong to haplogroup L0. Distribution L0 is found most commonly in Sub-Saharan Africa. It reaches its highest frequency in the Khoisan people at 73% on average. Some of the highest frequencies are: Namibia ( !Xun) 79%, South Africa ...

L0 Norm
In mathematics, the spaces are function spaces defined using a natural generalization of the -norm for finite-dimensional vector spaces. They are sometimes called Lebesgue spaces, named after Henri Lebesgue , although according to the Bourbaki group they were first introduced by Frigyes Riesz . spaces form an important class of Banach spaces in functional analysis, and of topological vector spaces. Because of their key role in the mathematical analysis of measure and probability spaces, Lebesgue spaces are used also in the theoretical discussion of problems in physics, statistics, economics, finance, engineering, and other disciplines. Applications Statistics In statistics, measures of central tendency and statistical dispersion, such as the mean, median, and standard deviation, are defined in terms of metrics, and measures of central tendency can be characterized as solutions to variational problems. In penalized regression, "L1 penalty" and "L2 penalty" refer to penaliz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L0 Series
The is a high-speed maglev train that the Central Japan Railway Company (JR Central) is developing and testing. JR Central plans to use the L0 series on the Chūō Shinkansen railway line between Tokyo and Osaka, which is under construction. The L0 series uses the Japanese-designed SCMaglev system. Mitsubishi Heavy Industries and Nippon Sharyo, a subsidiary of JR Central, are building fourteen pre-production vehicles. A seven-car train set a land speed record for rail vehicles of on 21 April 2015. The trains are planned to run at a maximum speed of , offering journey times of 40 minutes between Tokyo (Shinagawa Station) and , and 1 hour 7 minutes between Tokyo and Osaka. Specifications The end cars of L0 series trainsets are long and carry 24 passengers. The nose extends for better aerodynamics and reduced noise in tunnels. Intermediate cars are long and carry 68 passengers each, which totals a 299 m long and 728 passengers train. Each row is four seats wide, one less than ...

JR Central
is the main railway company operating in the Chūbu (Nagoya) region of central Japan. It is officially abbreviated in English as JR Central and in Japanese as JR Tōkai ( ja, JR東海, links=no). ''Tōkai'' is a reference to the geographical region in which the company chiefly operates. JR Central's operational hub is Nagoya Station and the company's administrative headquarters are located in the JR Central Towers above the station. The busiest and longest railway line operated by JR Central is the Tōkaidō Main Line between and . The company also operates the Tōkaidō Shinkansen between and . Additionally it is responsible for the Chūō Shinkansen—a maglev service between Tokyo and Osaka, which is due to start operation between Tokyo and Nagoya in 2027. JR Central is Japan's most profitable and highest throughput high-speed-rail operator, carrying 138 million high-speed-rail passengers in 2009, considerably more than the world's largest airline.
