picture info	Paternal Grandfather Grandparents, individually known as grandmother and grandfather, are the parents of a person's father or mother – paternal or maternal. Every sexually-reproducing living organism who is not a genetic chimera has a maximum of four genetic grandparents, eight genetic great-grandparents, sixteen genetic great-great-grandparents, thirty-two genetic great-great-great-grandparents, sixty-four genetic great-great-great-great grandparents, etc. In the history of modern humanity, around 30,000 years ago, the number of modern humans who lived to be a grandparent increased. It is not known for certain what spurred this increase in longevity but largely results in the improved medical technology and living standard, but it is generally believed that a key consequence of three generations being alive together was the preservation of information which could otherwise have been lost; an example of this important information might have been where to find water in times of drought.

picture info	Patterson–Gimlin Film The Patterson–Gimlin film (also known as the Patterson film or the PGF) is an American short motion picture of an unidentified subject that the filmmakers have said was a Bigfoot. The footage was shot in 1967 in Northern California, and has since been subjected to many attempts to authenticate or debunk it. The footage was filmed alongside Bluff Creek, a tributary of the Klamath River, about northwest of Orleans, California, Orleans, California, in Del Norte County on the Six Rivers National Forest. The film site is roughly south of Oregon and east of the Pacific Ocean. For decades, the exact location of the site was lost, primarily because of re-growth of foliage in the streambed after the flood of 1964. It was rediscovered in 2011. It is just south of a north-running segment of the creek informally known as "the bowling alley". The filmmakers were Roger Patterson (1933–1972) and Robert "Bob" Gimlin (born 1931). Patterson died of cancer in 1972 and "maintained right to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Placental Growth Factor Placental growth factor (PlGF) is a protein that in humans is encoded by the ''PGF'' gene. Placental growth factor (PGF) is a member of the VEGF (vascular endothelial growth factor) sub-family - a key molecule in angiogenesis and vasculogenesis, in particular during embryogenesis. The main source of PGF during pregnancy is the placental trophoblast. PGF is also expressed in many other tissues, including the villous trophoblast. The placental growth factor (PGF) gene is a protein-coding gene and a member of the vascular endothelial growth factor (VEGF) family. The PGF gene is expressed only in human umbilical vein endothelial cells (HUVE) and the placenta. PGF is ultimately associated with angiogenesis. Specifically, PGF plays a role in trophoblast growth and differentiation. Trophoblast cells, specifically extravillous trophoblast cells, are responsible for invading the uterine wall and the maternal spiral arteries. The extravillous trophoblast cells produce a blood vessel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	PGF/TikZ PGF/Ti''k''Z is a pair of languages for producing vector graphics (e.g., technical illustrations and drawings) from a geometric/algebraic description, with standard features including the drawing of points, lines, arrows, paths, circles, ellipses and polygons. PGF is a lower-level language, while Ti''k''Z is a set of higher-level macros that use PGF. The top-level PGF and Ti''k''Z commands are invoked as TeX macros, but in contrast with PSTricks, the PGF/Ti''k''Z graphics themselves are described in a language that resembles MetaPost. Till Tantau is the designer of the PGF and Ti''k''Z languages. He is also the main developer of the only known interpreter for PGF and Ti''k''Z, which is written in TeX. PGF is an acronym for "Portable Graphics Format". Ti''k''Z was introduced in version 0.95 of PGF, and it is a recursive acronym for "Ti''k''Z ist ''kein'' Zeichenprogramm" (German for "Ti''k''Z is ''not'' a drawing program"). Overview The PGF/Ti''k''Z interpreter can be used from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Precision Guided Firearm Precision guided firearms (PGFs) are long-range rifle systems designed to improve the accuracy of shooting at targets at extended ranges through target tracking, heads-up display, and advanced fire control. Inspired by missile lock-on and fighter jet technology, the application of PGF technology to small arms mitigates multiple sources of marksman error including mis-aim, trigger jerk and shot setup miscalculation.Wawro, Alex (Jan. 9, 2013)“The Hunting Rifle of the Future is Here at CES.”''PC World''.

PGFs can significantly increase first shot success probability (FSSP) out to extreme ranges of 1,100 meters or more. PGFs are fully integrated systems consisting of a rifle, networked tracking scope, guided trigger and precision conventional ammunition based on standard caliber bolt action or semi-automatic r ...

	Probability-generating Function In probability theory, the probability generating function of a discrete random variable is a power series representation (the generating function) of the probability mass function of the random variable. Probability generating functions are often employed for their succinct description of the sequence of probabilities Pr(''X'' = ''i'') in the probability mass function for a random variable ''X'', and to make available the well-developed theory of power series with non-negative coefficients. Definition Univariate case If ''X'' is a discrete random variable taking values in the non-negative integers , then the ''probability generating function'' of ''X'' is defined as http://www.am.qub.ac.uk/users/g.gribakin/sor/Chap3.pdf :G(z) = \operatorname (z^X) = \sum_^p(x)z^x, where ''p'' is the probability mass function of ''X''. Note that the subscripted notations ''G''''X'' and ''pX'' are often used to emphasize that these pertain to a particular random variable ''X'', and to its ...
