Unitary Group
In mathematics, the unitary group of degree ''n'', denoted U(''n''), is the group of unitary matrices, with the group operation of matrix multiplication. The unitary group is a subgroup of the general linear group . Hyperorthogonal group is an archaic name for the unitary group, especially over finite fields. For the group of unitary matrices with determinant 1, see Special unitary group. In the simple case , the group U(1) corresponds to the circle group, consisting of all complex numbers with absolute value 1, under multiplication. All the unitary groups contain copies of this group. The unitary group U(''n'') is a real Lie group of dimension ''n''2. The Lie algebra of U(''n'') consists of skew-Hermitian matrices, with the Lie bracket given by the commutator. The general unitary group (also called the group of unitary similitudes) consists of all matrices ''A'' such that ''A''∗''A'' is a nonzero multiple of the identity matrix, and is just the product of the unitary gr ...

LNER Class U1
The London and North Eastern Railway Class U1 was a solitary Beyer-Garratt locomotive designed for banking coal trains over the Worsborough Bank, a steeply graded line in South Yorkshire and part of the Woodhead Route. It was both the longest and the most powerful steam locomotive ever to run in Britain. It was built in 1925 with the motion at each end being based on an existing 2-8-0 design. The original number was 2395, and it was renumbered 9999 in March 1946, and then 69999 after nationalisation in 1948, although it retained its cab-side plate bearing its original number throughout its life. The locomotive ran for some time as an oil burner, and was tried out on the Lickey Incline in 1949–1950 and again, after the electrification of its home line, in 1955. These trials were unsuccessful, and so the locomotive was withdrawn in 1955 and scrapped. Origins The Worsborough Bank, sometimes referred to as the Worsborough Incline, was a steep bank on the Great Central Railway (G ...

U1 Spliceosomal RNA
U1 spliceosomal RNA is the small nuclear RNA (snRNA) component of U1 snRNP (''small nuclear ribonucleoprotein''), an RNA-protein complex that combines with other snRNPs, unmodified pre-mRNA, and various other proteins to assemble a spliceosome, a large RNA-protein molecular complex upon which splicing of pre-mRNA occurs. Splicing, or the removal of introns, is a major aspect of post-transcriptional modification, and takes place only in the nucleus of eukaryotes. Structure and function In humans, the U1 spliceosomal RNA is 164 bases long, forms four stem-loops, and possesses a 5'-trimethylguanosine five-prime cap. Bases 3 to 10 are a conserved sequence that base-pairs with the 5' splice site of introns during RNA splicing, and bases 126 to 133 form the Sm site, around which the Sm ring is assembled. Stem-loop I binds to the U1-70K protein, stem-loop II binds to the U1 A protein, stem-loops III and IV bind to the core RNP domain, a heteroheptameric Sm ring consisting of SmB/B', S ...

Unemployment
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is people above a specified age (usually 15) not being in paid employment or self-employment but currently available for Work (human activity), work during the reference period. Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed). Unemployment can have many sources, such as the following: * new technology, technologies and inventions * the status of the economy, which can be influenced by a recession * competition caused by globalization and international trade * Policy, policies of the government * regulation and market (economics), market Unemployment and the status of the economy can be influenced by a country through, for example, fiscal policy. Furthermore, the monetary authority of a country, such as the central bank, can influ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple U1
Apple silicon is a series of system on a chip (SoC) and system in a package (SiP) processors designed by Apple Inc., mainly using the ARM architecture. It is the basis of most new Mac computers as well as iPhone, iPad, iPod Touch, Apple TV, and Apple Watch, and of products such as AirPods, HomePod, HomePod Mini, and AirTag. Apple announced its plan to switch Mac computers from Intel processors to Apple silicon at WWDC 2020 on June 22, 2020. The first Macs built with the Apple M1 processor were unveiled on November 10, 2020. In 2022, the newest Mac models were built with Apple silicon; only older models of the Mac Mini and the Mac Pro still use Intel Core and Xeon processors respectively. Apple fully controls the integration of Apple silicon chips with the company's hardware and software products. Johny Srouji is in charge of Apple's silicon design. Manufacturing of the chips is outsourced to semiconductor contract manufacturers such as Samsung and TSMC. A series ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secure Digital
Secure Digital, officially abbreviated as SD, is a proprietary format, proprietary non-volatile memory, non-volatile Flash memory, flash memory card format developed by the SD Association, SD Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCard, MultiMediaCards (MMCs), and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. History 1999–2003: Creation In 1 ...

U1 (Nuremberg U-Bahn)
The U1 is an underground line in Nuremberg U-Bahn, Nuremberg. The first part of the line was opened on 1 March 1972. It is about long and has 27 stations. The termini are Langwasser Süd (Nuremberg U-Bahn), Langwasser Süd in the southeast and Hardhöhe (Nuremberg U-Bahn), Fürth Hardhöhe in the northwest. Until 11 December 2016 it shared tracks with the former booster line U11 between Eberhardshof and Messe. Those services are still run but no longer designated U11, instead being signed U1 like trains doing the full Langwasser-Hardhöhe run. Unlike U2 and U3 all trains are operated by a driver and there are no plans to automate U1. History Unlike in Munich U-Bahn, Munich where line designations were based on previous Trams in Munich, tramway lines - line U6 was the first to open, but designated number 6 based on a previous tram line 6 - or Berlin U-Bahn, Berlin where line numbers in the modern sense were only given out decades after the system opened and U1 and U2 do inde ...

U1 (Frankfurt U-Bahn)
The A line is the north-to-south main line of the Frankfurt U-Bahn. It is the oldest and longest line of the U-Bahn system. Served by four routes (U1, U2, U3 and U8) starting at ''Südbahnhof Railway Station'' in Sachsenhausen, the A line runs through downtown Frankfurt up to ''Heddernheim Station'' in the north of the city, where it branches out to Ginnheim (U1 and U9), Oberursel (U3), Riedberg (U8 and U9) and Bad Homburg (U2). The U9 service between Ginnheim, Riedberg and Nieder-Eschbach does not use the central section and tunnels of the line, making it the only light rail service of the network that does not serve downtown Frankfurt. The Riedberg and Ginnheim branches were planned as parts of the future ''D line subway'' but are operationally part of the A line until the D line development and construction is finished. History The Line A with its three connecting lines covers about half of the Frankfurt subway network and combines various upgrade standards, linking subway, e ...
