Haplogroup L4 is a human mitochondrial DNA (mtDNA) haplogroup. It is a small maternal clade primarily restricted to Africa. [2] Projected spatial frequency distribution for haplogroup L4. Schematic tree of mtDNA haplogroup L4. Ages (in ka) indicated are maximum likelihood estimates obtained for the whole-mtDNA genome. L4 is important in East ...
The highest frequency (18.2%) of Sub-Saharan lineages found so far in Europe were observed by Alvarez et al. 2010 in the comarca of Sayago in Spain and in Alcacer do Sal in Portugal. [33] [34] In Italy, Haplogroup L lineages are present in some regions at frequencies between 2 and 3% in Latium (2.90%), parts of Tuscany, [28] Basilicata and ...
This was considered necessary because L4/Fiasco is used as the basis of DROPS, [6] a hard real-time computing capable operating system, also developed at the TU Dresden. However, the complexities of a fully preemptible design prompted later versions of Fiasco to return to the traditional L4 approach of running the kernel with interrupts ...
A hypothetical planet-sized Earth trojan the size of Mars, given the name Theia, is thought by proponents of the giant-impact hypothesis to be the origin of the Moon.The hypothesis states that the Moon formed after Earth and Theia collided, [10] showering material from the two planets into space.
I wanted to go into machine learning because it was a rapidly developing field being used to solve hard problems like spam reduction. With my research experience and high college grades, a Ph.D ...

Asteroid (419624) 2010 SO 16, in a horseshoe companion orbit with Earth, is currently proximal to L 5 but at a high inclination. STEREO B (Solar TErrestrial RElations Observatory – Behind) made its closest pass to L 5 in October 2009, on its orbit around the Sun, slightly slower than Earth.
Why is norovirus so hard to kill? The most reliable way to stop the spread is washing your hands with soap and water for at least 20 seconds , especially if you are preparing food, or after using ...
