Haplogroup L2 (mtDNA)
Haplogroup L2 is a Human mitochondrial DNA haplogroup, human mitochondrial DNA (mtDNA) haplogroup with a widespread modern distribution, particularly in Subequatorial Africa. Its L2a subclade is a somewhat frequent and widely distributed mtDNA cluster on the continent, as well as among those in the Americas. Origin L2 is a common lineage in Africa. It is believed to have evolved between 87,000 and 107,000 years ago or approx. 90,000 YBP. Its age and widespread distribution and diversity across the continent makes its exact origin point within Africa difficult to trace with any confidence. Several L2 haplotypes observed in Guineans and other West Africa populations shared genetic matches with East Africa and North Africa. An origin for L2b, L2c, L2d and L2e in West or Central Africa seems likely. The early diversity of L2 can be observed all over the African Continent, but as we can see in Subclades section below, the highest diversity is found in West Africa. Most of subclades are ...

GPS Signals
GPS signals are broadcast by Global Positioning System satellites to enable satellite navigation. Using these signals, receivers on or near the Earth's surface can determine their Position, Velocity and Time (PVT). The GPS satellite constellation is operated by the 2nd Space Operations Squadron (2SOPS) of Space Delta 8, United States Space Force. GPS signals include ranging signals, which are used to measure the distance to the satellite, and navigation messages. The navigation messages include ephemeris data which are used both in trilateration to calculate the position of each satellite in orbit and also to provide information about the time and status of the entire satellite constellation, called the almanac. There are four GPS signal specifications designed for civilian use. In order of date of introduction, these are: L1 C/A, L2C, L5 and L1C. L1 C/A is also called the ''legacy signal'' and is broadcast by all currently operational satellites. L2C, L5 and L1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L2 Cache
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have a hierarchy of multiple cache levels (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1. The cache memory is typically implemented with static random-access memory (SRAM), in modern CPUs by far the largest part of them by chip area, but SRAM is not always used for all levels (of I- or D-cache), or even any level, sometimes some latter or all levels are implemented with eDRAM. Other types of caches exist (that are not counted towards the "cache size" of the most important caches mentioned above), such as the translation lookaside buffer (TLB) which is part of the memory management unit (MMU) whic ...

Lumines II
is a 2006 puzzle video game developed by Q Entertainment for the PlayStation Portable (PSP). It was released in November 2006 in the PAL region and North America by Buena Vista Games, and in February 2007 in Japan by Bandai Namco Games. The objective of the game is to move and rotate 2×2 blocks to form colored squares of the same color. Points are awarded to the player when the Time Line erases the colored squares. It serves as a direct sequel to '' Lumines: Puzzle Fusion'', expanding on previous modes from its predecessor and adding new modes such as Mission mode, Skin Edit mode, and Sequencer. ''Lumines II'' utilizes songs from its predecessor and introduces music videos as background skins from Japanese music artists and mainstream American music artists such as New Order, Missy Elliot, and Beck. When developing the game, game producer Tetsuya Mizuguchi intended to make the game have a different atmosphere than its predecessor and wanted to include more songs. Mizuguchi fu ...

Sterling Submachine Gun
The Sterling submachine gun is a British submachine gun (SMG). It was tested by the British Army in 1944–1945, but did not start to replace the Sten until 1953. A successful and reliable design, it remained standard issue in the British Army until 1994, when it began to be replaced by the L85A1, a bullpup assault rifle. History In 1944, the British General Staff issued a specification for a new submachine gun to replace the Sten. It stated that the new weapon should weigh no more than six pounds (2.7 kg), should fire 9×19mm Parabellum ammunition, have a rate of fire of no more than 500 rounds per minute, and be sufficiently accurate to allow five consecutive shots (fired in semi-automatic mode) to be placed inside a one-foot-square (30 cm × 30 cm) target at a distance of . To meet the new requirement, George William Patchett, the chief designer at the Sterling Armaments Company of Dagenham, submitted a sample weapon of new design in early 1944. The fi ...

L2 Point
In celestial mechanics, the Lagrange points (; also Lagrangian points or libration points) are points of equilibrium for small-mass objects under the gravitational influence of two massive orbiting bodies. Mathematically, this involves the solution of the restricted three-body problem. Normally, the two massive bodies exert an unbalanced gravitational force at a point, altering the orbit of whatever is at that point. At the Lagrange points, the gravitational forces of the two large bodies and the centrifugal force balance each other. This can make Lagrange points an excellent location for satellites, as orbit corrections, and hence fuel requirements, needed to maintain the desired orbit are kept at a minimum. For any combination of two orbital bodies, there are five Lagrange points, L1 to L5, all in the orbital plane of the two large bodies. There are five Lagrange points for the Sun–Earth system, and five ''different'' Lagrange points for the Earth–Moon system. L1, L ...

M61 Grenade
The M26 is a fragmentation hand grenade developed by the United States military. It entered service in 1952 and was first used in combat during the Korean War, replacing the Mk 2 of World War II. The M26 series was the primary fragmentation grenade used by American forces in the Vietnam War. It was replaced by the M33 series grenade. Its distinct lemon shape led it to being nicknamed the "lemon grenade" (compare the Russian F1 and American Mk 2 "pineapple" grenades). History The M26 series was created after World War II to meet criticisms of the Mk 2. Rather than relying on a cast body to produce fragments like the Mk 2 the M26 had a thin sheet-metal body and the fragments were instead created by a notched wire coiled up inside which produced smaller fragments but a greater number traveling at a higher velocity and distributed them more evenly than the Mk 2, giving it a larger effective casualty producing radius. The fragments were also more consistently sized posing less o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L2 Puppis
L2 Puppis (also known as HD 56096) is a giant star in the constellation of Puppis and is located between the bright stars Canopus and Sirius. It is a Semiregular variable star, semi-regular pulsating star, and is intermittently visible to the naked eye. History The designation L2 has a tangled history. This star and another (OU Puppis) were both labelled with "L" by Nicolas-Louis de Lacaille when he created the constellation Puppis within Argo Navis. The two stars were labelled as "1.L" and "2.L" by Johann Elert Bode in his star catalogue published in 1801. Later authors used L1 and L2, usually with numeric subscripts (i.e. L1 and L2), but occasionally as superscripts. The subscripted designation is now universally used where typography allows for subscripts. L2 Puppis was discovered to be variable by Benjamin Apthorp Gould in 1872, and was listed in Uranometria Argentina as 73 G. Puppis with magnitude 5.10v. It has never been given a formal variable star designation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
