Dawson's Integral
In mathematics, the Dawson function or Dawson integral (named after H. G. Dawson) is the one-sided Fourier–Laplace sine transform of the Gaussian function. Definition The Dawson function is defined as either: D_+(x) = e^ \int_0^x e^\,dt, also denoted as F(x) or D(x), or alternatively D_-(x) = e^ \int_0^x e^\,dt.\! The Dawson function is the one-sided Fourier–Laplace sine transform of the Gaussian function, >D_+(x) = \frac12 \int_0^\infty e^\,\sin(xt)\,dt. It is closely related to the error function erf, as : D_+(x) = e^ \operatorname (x) = - e^ \operatorname (ix) where erfi is the imaginary error function, Similarly, D_-(x) = \frac e^ \operatorname(x) in terms of the real error function, erf. In terms of either erfi or the Faddeeva function w(z), the Dawson function can be extended to the entire complex plane:Mofreh R. Zaghloul and Ahmed N.

Dawson's 19th Arkansas Infantry Regiment
The 19th (Dawson's) Arkansas Infantry (1861–1865) was a Confederate Army infantry regiment during the American Civil War. The regiment was present for but not engaged during the Battle of Pea Ridge. At the Battle of Arkansas Post, the regiment became split, with part of the regiment surrendering with the garrison when the post capitulated. The captured portion of the regiment was eventually exchanged and released on the east side of the Mississippi and served the remainder of the war with the Confederate Army of Tennessee. The un-captured portion of the regiment was consolidated with the remnants of the 24th Arkansas and served the remainder of the war in the Department of the Trans-Mississippi. Organization 19th (Dawson's) Infantry Regiment completed its organization at Nashville, Arkansas, in November 1861. The field officers were Colonel C. L. Dawson; Lieutenant Colonels A. S. Hutchison and P. R. Smith; and Majors Joseph Anderson, David H. Hamiter, and John G. McKean. The u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dawson's Burrowing Bee
''Amegilla dawsoni'', sometimes called the Dawson's burrowing bee, is a species of bee that nests by the thousands in arid claypans in Western Australia. It is a long tongued bee, of the tribe Anthophorini and genus ''Amegilla,'' the second largest genus in Anthophorini. The Dawson's burrowing bee is one of the largest Australian bee species, growing to be in length and in wingspan. With the exception of their faces, the bees are covered in brown fur, if male, or brown and white fur if female. They are similar in size and coloring to Australian carpenter bees. They are known solitary nesters. Though each female bee will build her own nest, they aggregate in large communities that give the appearance of colonies. Their nests are dug into the ground, with individual capsules created for each brood cell. Each female will only breed once in their breeding season. The males of the species are dimorphic, based on brood provisioning strategies during development. The larger males ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dawson's Caribou
The Queen Charlotte Islands caribou or Dawson's caribou (''Rangifer arcticus dawsoni'') is an extinct subspecies of the Arctic caribou (''R. arcticus'') that once lived on Graham Island, the largest of the islands of Haida Gwaii in British Columbia, Canada. Possible causes of its extinction include habitat destruction, introduced disease and overhunting Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term app .... It was grey in appearance. The last three caribou were killed in 1908 and can be seen at the Royal British Columbia Museum, where their pelts and bones are preserved and displayed. Recent analysis of mtDNA suggests that the Queen Charlotte Islands caribou was not genetically distinct from the subspecies from the Canadian mainland.Byun, S.A.; B.F. Koop, and T.E. Reimchen.

Dawson's Cat Shark
The New Zealand catshark, ''Bythaelurus dawsoni'', is a catshark of the family Scyliorhinidae in the order Carcharhiniformes. This species is endemic to in the deep waters around New Zealand. Its length is up to . The New Zealand catshark is a small, little-known deep water bottom shark. It is dark brown around the top with a few widely spaced pale spots, and white below. It feeds on bottom-living crustaceans. It is also completely harmless to humans. Conservation status The New Zealand Department of Conservation has classified the New Zealand catshark as "Not Threatened" but with the qualifier "Data Poor" under the New Zealand Threat Classification System The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand. The system was developed because the IUCN Red List, a similar conservation status system, had some .... It is regarded as being at risk from bottom trawling. References ...

Dawson's Chess
Hexapawn is a deterministic two-player game invented by Martin Gardner. It is played on a rectangular board of variable size, for example on a 3×3 board or on a regular chessboard. On a board of size ''n''×''m'', each player begins with ''m'' pawns, one for each square in the row closest to them. The goal of each player is to either advance a pawn to the opposite end of the board or leave the other player with no legal moves. Hexapawn on the 3×3 board is a solved game; with perfect play, White will always lose in 3 moves (1.b2 axb2 2.cxb2 c2 3.a2 c1#). Indeed, Gardner specifically constructed it as a game with a small game tree in order to demonstrate how it could be played by a heuristic AI implemented by a mechanical computer based on Donald Michie's Matchbox Educable Noughts and Crosses Engine. A variant of this game is octopawn, which is played on a 4×4 board with 4 pawns on each side. It is a forced win for White. Rules As in chess, a pawn may be moved in two d ...

Dawson's Dawn-man
The Piltdown Man was a paleoanthropological fraud in which bone fragments were presented as the fossilised remains of a previously unknown early human. Although there were doubts about its authenticity virtually from the beginning, the remains were still broadly accepted for many years, and the falsity of the hoax was only definitively demonstrated in 1953. An extensive scientific review in 2016 established that amateur archaeologist Charles Dawson was responsible for the fraudulent evidence. In 1912, Charles Dawson claimed that he had discovered the " missing link" between ape and man. In February 1912, Dawson contacted Arthur Smith Woodward, Keeper of Geology at the Natural History Museum, stating he had found a section of a human-like skull in Pleistocene gravel beds near Piltdown, East Sussex. That summer, Dawson and Smith Woodward purportedly discovered more bones and artifacts at the site, which they connected to the same individual. These finds included a jawbone, more ...

Dawson's Encephalitis
Subacute sclerosing panencephalitis (SSPE)—also known as Dawson disease—is a rare form of chronic, progressive brain inflammation caused by slow infection with certain defective strains of hypermutated measles virus. The condition primarily affects children, teens, and young adults. It has been estimated that about 2 in 10,000 people who get measles will eventually develop SSPE. However, a 2016 study estimated that the rate for unvaccinated infants under 15 months was as high as 1 in 609. No cure for SSPE exists, and the condition is almost always fatal. SSPE should not be confused with acute disseminated encephalomyelitis, which can also be caused by the measles virus, but has a very different timing and course. SSPE is caused by the wild-type virus, not by vaccine strains. Signs and symptoms SSPE is characterized by a history of primary measles infection, followed by an asymptomatic period that lasts 7 years on average but can range from 1 month to 27 years. After the asy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dawson's Field Hijackings
In September 1970, members of the Popular Front for the Liberation of Palestine (PFLP) hijacked four airliners bound for New York City and one for London. Three aircraft were forced to land at Dawson's Field, a remote desert airstrip near Zarqa, Jordan, formerly Royal Air Force Station Zarqa, which then became PFLP's "Revolutionary Airport". By the end of the incident, one hijacker had been killed and one injury reported. This was the second instance of mass aircraft hijacking, after an escape from communist Czechoslovakia in 1950. On 6 September, TWA Flight 741 from Frankfurt (a Boeing 707) and Swissair Flight 100 from Zürich (a Douglas DC-8) were forced to land at Dawson's Field.BBC News, "On This Day: 12 September". On the same day, the hijacking of El Al Flight 219 from Amsterdam (another 707) was foiled: hijacker Patrick Argüello was shot and killed, and his partner Leila Khaled was subdued and handed over to British authorities in London. Two PFLP hijackers, who we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dawson's Fingers
Multiple sclerosis and other demyelinating diseases of the central nervous system (CNS) produce lesions (demyelinated areas in the CNS) and glial scars or scleroses. They present different shapes and histological findings according to the underlying condition that produces them. Demyelinating diseases are traditionally classified in two kinds: demyelinating myelinoclastic diseases and demyelinating leukodystrophic diseases. In the first group a normal and healthy myelin is destroyed by a toxic, chemical or autoimmune substance. In the second group, myelin is abnormal and degenerates. The second group was denominated dysmyelinating diseases by Poser Therefore, since Poser demyelinating diseases normally refers to the myelinoclastic part. Demyelinating diseases of the CNS can be classified according to their pathogenesis into five non-exclusing categories: demyelination due to inflammatory processes, viral demyelination, demyelination caused by acquired metabolic derangements, hyp ...
