Generalized Dirichlet Distribution
In statistics, the generalized Dirichlet distribution (GD) is a generalization of the Dirichlet distribution with a more general covariance structure and almost twice the number of parameters. Random vectors with a GD distribution are completely neutral. The density function of p_1,\ldots,p_ is : \left \prod_^B(a_i,b_i)\right p_k^ \prod_^\left p_i^\left(\sum_^kp_j\right)^\right where we define p_k= 1- \sum_^p_i. Here B(x,y) denotes the Beta function. This reduces to the standard Dirichlet distribution if b_=a_i+b_i for 2\leqslant i\leqslant k-1 (b_0 is arbitrary). For example, if ''k=4'', then the density function of p_1,p_2,p_3 is : \left prod_^B(a_i,b_i)\right p_1^p_2^p_3^p_4^\left(p_2+p_3+p_4\right)^\left(p_3+p_4\right)^ where p_1+p_2+p_3<1 and .

Soman
Soman (or GD, EA 1210, Zoman, PFMP, A-255, systematic name: ''O''-pinacolyl methylphosphonofluoridate) is an extremely toxic chemical substance. It is a nerve agent, interfering with normal functioning of the mammalian nervous system by inhibiting the enzyme cholinesterase. It is an inhibitor of both acetylcholinesterase and butyrylcholinesterase. As a chemical weapon, it is classified as a weapon of mass destruction by the United Nations according to UN Resolution 687. Its production is strictly controlled, and stockpiling is outlawed by the Chemical Weapons Convention of 1993 where it is classified as a Schedule 1 substance. Soman was the third of the so-called ''G-series'' nerve agents to be discovered along with GA (tabun), GB (sarin), and GF (cyclosarin). When pure, soman is a volatile, corrosive, and colorless liquid with a faint odor like that of mothballs or rotten fruit. More commonly, it is a yellow to brown color and has a strong odor described as similar to c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poste Restante
(, "waiting mail"), also known as general delivery in North American English, is a service where the post office holds the mail until the recipient calls for it.

Gangster Disciples
The Gangster Disciple Nation (often abbreviated as the GD's; formally, GDN or simply Gangster Disciples), also known as Growth & Development, is an African American street and prison gang founded by former rivals David Barksdale and Larry Hoover; in 1968, the two came together to form the Black Gangster Disciple Nation (BGDN). Post-1989, following growing tension between the two over declining leadership, the BGDN split into two new factions—Hoover's Gangster Disciple Nation (GDN) and Barksdale's Black Disciple Nation (BDN), respectively. As of 2022, following Hoover's departure, the GDN has no full-time leadership role. History The origins of the Gangster Disciples began in Englewood (in Chicago, Illinois's South Side) in 1964, when then 13-year-old Larry 'The King' Hoover joined a small street gang called the 'Supreme Gangsters'. For years, the Supreme Gangsters had an outstanding war with the Black Disciples Nation, led by David Barksdale. In 1969, Hoover and Bar ...

Guangdong
) means "wide" or "vast", and has been associated with the region since the creation of Guang Prefecture in AD 226. The name "''Guang''" ultimately came from Guangxin ( zh, labels=no, first=t, t= , s=广信), an outpost established in Han dynasty near modern Wuzhou, whose name is a reference to an order by Emperor Wu of Han to "widely bestow favors and sow trust". Together, Guangdong and Guangxi are called ''Liangguang, Loeng gwong'' ( zh, labels=no, first=t, t=兩廣, s=两广 , p=liǎng guǎng) During the Song dynasty, the Two Guangs were formally separated as ''Guǎngnán Dōnglù'' ( zh, first=t, t=廣南東路, s=广南东路, l=East Circuit (administrative division), Circuit in Southern Guang , labels=no) and ''Guǎngnán Xīlù'' ( zh, first=t, t=廣南西路, s=广南西路, l=West Circuit (administrative division), Circuit in Southern Guang , labels=no), which became abbreviated as ''Guǎngdōng Lù'' ( zh, first=t, t=廣東路, s=广东路 , labels=no) and ''Guǎngxī Lù ...

Gudermannian Function
In mathematics, the Gudermannian function relates a hyperbolic angle measure \psi to a circular angle measure \phi called the ''gudermannian'' of \psi and denoted \operatorname\psi. The Gudermannian function reveals a close relationship between the circular functions and hyperbolic functions. It was introduced in the 1760s by Johann Heinrich Lambert, and later named for Christoph Gudermann who also described the relationship between circular and hyperbolic functions in 1830. The gudermannian is sometimes called the hyperbolic amplitude as a limiting case of the Jacobi elliptic amplitude \operatorname(\psi, m) when parameter m=1. The real Gudermannian function is typically defined for -\infty < \psi < \infty to be the integral of the hyperbolic secant : The real inverse Gudermannian function can be defined for |
