Bra–ket Notation
Bra–ket notation, also called Dirac notation, is a notation for linear algebra and linear operators on complex vector spaces together with their dual space both in the finite-dimensional and infinite-dimensional case. It is specifically designed to ease the types of calculations that frequently come up in quantum mechanics. Its use in quantum mechanics is quite widespread. Bra–ket notation was created by Paul Dirac in his 1939 publication ''A New Notation for Quantum Mechanics''. The notation was introduced as an easier way to write quantum mechanical expressions. The name comes from the English word "bracket". Quantum mechanics In quantum mechanics and quantum computing, bra–ket notation is used ubiquitously to denote quantum states. The notation uses angle brackets, and , and a vertical bar , to construct "bras" and "kets". A ket is of the form , v \rangle. Mathematically it denotes a vector, \boldsymbol v, in an abstract (complex) vector space V, and physicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Key English Test
A2 Key, previously known as Cambridge English: Key and the Key English Test (KET), is an English language examination provided by Cambridge Assessment English (previously known as Cambridge English Language Assessment and University of Cambridge ESOL examinations). A2 Key is targeted at novice students of English. It tests for proficiency in simple communication to Level A2 of the Common European Framework of Reference (CEFR). A2 Key offers two versions: one for school-aged learners; and for general education. History A2 Key (previously known as the Key English Test (KET) and Cambridge English: Key) was developed through trials conducted between 1991 and 1994. It was created to offer students a basic qualification in English and provide the first step for those wishing to progress towards higher level qualifications, such as B1 Preliminary, B2 First, C1 Advanced, and C2 Proficiency. An updated version of A2 Key was launched in March 2004, following a review with stakeho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ketamine
Ketamine is a cyclohexanone-derived general anesthetic and NMDA receptor antagonist with analgesic and hallucinogenic properties, used medically for anesthesia, depression, and pain management. Ketamine exists as its S- (esketamine) and R- (arketamine) two enantiomers and has antidepressant action likely involving additional mechanisms than NMDA antagonism. At anesthetic doses, ketamine induces a state of dissociative anesthesia, a trance-like state providing pain relief, sedation, and amnesia. Its distinguishing features as an anesthestic are preserved breathing and airway reflexes, stimulated heart function with increased blood pressure, and moderate bronchodilation. As an anesthetic, it is used especially in trauma, Emergency medical services, emergency, and Pediatrics, pediatric cases. At lower, sub-anesthetic doses, it is used as a treatment for pain and treatment-resistant depression. Ketamine is legally used in medicine but is also tightly controlled due to ...

Ket Language
The Ket ( ) language, or more specifically Imbak and formerly known as Yenisei Ostyak ( ), is a Siberian language long thought to be an isolate, the sole surviving language of a Yeniseian language family. It is spoken along the middle Yenisei basin by the Ket people. The language is threatened with extinction—the number of ethnic Kets that are native speakers of the language dropped from 1,225 in 1926 to 537 in 1989. According to the UNESCO census, this number has since fallen to 150. A 2005 census reported 485 native speakers, but this number is suspected to be inflated. According to a local news source, the number of remaining Ket speakers is around 10 to 20. Another Yeniseian language, Yugh, has recently become extinct. History Documentation The earliest observations about the language were published by Peter Simon Pallas in 1788 in a travel diary (, ). Matthias Castrén was one of the last known to study the Kott language. Castrén lived beside the Kan river ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kennedy Town Station
Kennedy Town () is the western terminus of the . The station serves the Kennedy Town area on the northwestern end of Hong Kong Island, Hong Kong. History Planning When the station first appeared in ''Hong Kong Mass Transit: Further Studies'' plan in 1970, it was simply known as Kennedy (). It was to be built as part of the Island line in the 1980s, but construction of the line did not commence westwards beyond , on account of contractors citing inadequate passenger numbers and technical difficulties. Under the latest proposal as of June 2005, Kennedy Town would be served by West Island line as an extension of the Island line, a heavy rail system, instead of being served by a medium capacity rail shared by commuters from Southern District, after pressure from local community groups. Construction The station was designed by TFP Farrells. The contract to construct the station and overrun tunnel was awarded to Gammon Construction (half owned by Balfour Beatty Balfour Bea ...

Kettering Railway Station
Kettering railway station serves the market and industrial town of Kettering in Northamptonshire, England. It lies south-west of the town centre, on the Midland Main Line, north of London St. Pancras. History The station was opened in May 1857 by the Midland Railway, on a line linking the Midland to the Great Northern Railway at Hitchin. Later, the Midland gained its own London terminus at St Pancras railway station. In 1857, the leather trade was in recession and so over half of Kettering's population was on poor relief; the railway enabled the town to sell its products over a much wider area and restored it to prosperity. The original station with a single platform was designed by Charles Henry Driver, with particularly fine 'pierced grill' cast ironwork on the platform. In 1858, it was reported that the station was now lit by gas lamps with gas supplied from the town mains. It was also reported that the line was one of the very few without telegraphic wires.

Ket (software)
Ket is an open source algebra editor. It is distinct from editors like Mathematica and Maple and from typesetting systems like LaTeX in that its focus is primarily on interactivity, providing various features to allow for easy manipulation of algebraic equations, with the goal of providing a convenience comparable to text editors or handwriting. Overview Ket breaks the process of equation editing into a series of small edits performed either with the keyboard or with mouse gestures. Commands exist to delete, reorganize and combine existing expressions as well as to add new symbols or expressions. Equations often contain a great deal of repetition which can make it faster to reuse existing expressions than re-write them. Commands provide instantaneous updates enabling the user to view an equation in conventional mathematical notation while interacting with it as a series of small fragments. Representations Ket maintains three distinct representations of an equation. Firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ket (king)
Ket (; ), Ketchettharaj (, ''Keśaśreṣṭharāja''; ) or Mueangketklao (; ) was the 12th monarch of Lan Na from the Mangrai dynasty of the. He reigned twice: the first time from 1525–1538, and the second time from 1543–1545. During his first reign, which lasted 13 years, he was overthrown by his own son, Saikham. However, Saikham ruled for only 5 years before being deposed by the nobility.

Biography First Reign (1525–1538) Ket, or Ketchettharaj, was the son of King Sirithammachakkrapat, also known as Kaew. He was born in Mueang Noi, present-day Pai district in Mae Hong Son province. He ascended the throne in 1525 and initially retained the power base of his father without facing opposition from the nobility. This stability was supported by the monastic community and his grandmother, Siriyasawadee Devi, who formed part of the traditional powe ...
