Asymmetry
Asymmetry is the absence of, or a violation of, symmetry (the property of an object being invariant to a transformation, such as reflection). Symmetry is an important property of both physical and abstract systems and it may be displayed in precise terms or in more aesthetic terms. The absence of or violation of symmetry that are either expected or desired can have important consequences for a system. In organisms Due to how cells divide in organisms, asymmetry in organisms is fairly usual in at least one dimension, with biological symmetry also being common in at least one dimension. Louis Pasteur proposed that biological molecules are asymmetric because the cosmic .e. physicalforces that preside over their formation are themselves asymmetric. While at his time, and even now, the symmetry of physical processes are highlighted, it is known that there are fundamental physical asymmetries, starting with time. Asymmetry in biology Asymmetry is an important and widespread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymmetric Cryptography
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions. Security of public-key cryptography depends on keeping the private key secret; the public key can be openly distributed without compromising security. In a public-key encryption system, anyone with a public key can encrypt a message, yielding a ciphertext, but only those who know the corresponding private key can decrypt the ciphertext to obtain the original message. For example, a journalist can publish the public key of an encryption key pair on a web site so that sources can send secret messages to the news organization in ciphertext. Only the journalist who knows the corresponding private key can decrypt the ciphertexts to obtain the sources' messages—an eavesdropp ...

Asymmetric Digital Subscriber Line
Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL differs from the less common symmetric digital subscriber line (SDSL). In ADSL, bandwidth and bit rate are said to be asymmetric, meaning greater toward the customer premises (downstream) than the reverse (upstream). Providers usually market ADSL as an Internet access service primarily for downloading content from the Internet, but not for serving content accessed by others. Overview ADSL works by using spectrum above the band used by voice telephone calls. With a DSL filter, often called ''splitter'', the frequency bands are isolated, permitting a single telephone line to be used for both ADSL service and telephone calls at the same time. ADSL is generally only installed for short distances from the telephone exchange (the last m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymmetric Multiprocessing
An asymmetric multiprocessing (AMP or ASMP) system is a multiprocessor computer system where not all of the multiple interconnected central processing units (CPUs) are treated equally. For example, a system might allow (either at the hardware or operating system level) only one CPU to execute operating system code or might allow only one CPU to perform I/O operations. Other AMP systems might allow any CPU to execute operating system code and perform I/O operations, so that they were symmetric with regard to processor roles, but attached some or all peripherals to particular CPUs, so that they were asymmetric with respect to the peripheral attachment. Asymmetric multiprocessing was the only method for handling multiple CPUs before symmetric multiprocessing (SMP) was available. It has also been used to provide less expensive options on systems where SMP was available. Background and history For the room-size computers of the 1960s and 1970s, a cost-effective way to increase compute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymmetric Relation
In mathematics, an asymmetric relation is a binary relation R on a set X where for all a, b \in X, if a is related to b then b is ''not'' related to a. Formal definition A binary relation on X is any subset R of X \times X. Given a, b \in X, write a R b if and only if (a, b) \in R, which means that a R b is shorthand for (a, b) \in R. The expression a R b is read as "a is related to b by R." The binary relation R is called if for all a, b \in X, if a R b is true then b R a is false; that is, if (a, b) \in R then (b, a) \not\in R. This can be written in the notation of first-order logic as \forall a, b \in X: a R b \implies \lnot(b R a). A logically equivalent definition is: :for all a, b \in X, at least one of a R b and b R a is , which in first-order logic can be written as: \forall a, b \in X: \lnot(a R b \wedge b R a). An example of an asymmetric relation is the " less than" relation \,<\, between |
Asymmetric Synthesis
Enantioselective synthesis, also called asymmetric synthesis, is a form of chemical synthesis. It is defined by IUPAC as "a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereomeric) products in unequal amounts." Put more simply: it is the synthesis of a compound by a method that favors the formation of a specific enantiomer or diastereomer. Enantiomers are stereoisomers that have opposite configurations at every chiral center. Diastereomers are stereoisomers that differ at one or more chiral centers. Enantioselective synthesis is a key process in modern chemistry and is particularly important in the field of pharmaceuticals, as the different enantiomers or diastereomers of a molecule often have different biological activity. Overview Many of the building blocks of biological systems such as sugars and amino acids are produced exclusively as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymmetric Warfare
Asymmetric warfare (or asymmetric engagement) is the term given to describe a type of war between belligerents whose relative military power, strategy or tactics differ significantly. This is typically a war between a standing, professional army and an insurgency or resistance movement militias who often have status of unlawful combatants. ''Asymmetric warfare'' can describe a conflict in which belligerents' resources are uneven, consequently they both may attempt to exploit each other's characteristic weaknesses. Such struggles often involve unconventional warfare, with the weaker side attempting to use strategy to offset deficiencies in the quantity or quality of their forces and equipment. Such strategies may not necessarily be militarized. This is in contrast to ''symmetric warfare'', where two powers have comparable military power, resources, and rely on similar tactics. Asymmetric warfare is a form of irregular warfare – conflicts in which enemy combatants are not re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymmetric Publications
Asymmetric Publications is a video game developer and publisher. It made the web-based role-playing game ''Kingdom of Loathing''. Asymmetric is run by Zack Johnson (who is known as Jick in-game). Employees of the company are known as the Asymmetric Team. As a result of the popularity of the game, Asymmetric currently supports Johnson and a few other individuals as full-time employees. In the past, Asymmetric Publications hosted various games and other attractions, including ''Infinity Plus One'', an online fortune teller, ''Bee On Drugs'', a bee who rambles, and ''Krakrox the Barbarian'', a game noted as the precursor to ''Kingdom of Loathing''. A running gag was that the Asymmetric Publications' website was not updated for almost six years after the announcement of a "fun new game," ''Kingdom of Loathing''. In late 2008, it began to be updated again. The employees of Asymmetric Publications formerly produced several weekly podcasts. One of them was related to Kingdom of Loathin ...

Asymmetry (Mallory Knox Album)
''Asymmetry'' is the second album by British rock band Mallory Knox. It was released on 27 October 2014 via Search and Destroy and Epic Records and was produced by Gil Norton. It is the band's first release after departing from A Wolf at Your Door Records. Asymmetry charted at no. 16 in the UK album charts in the first week of sales. Like their debut album, it was released to very high positive reviews from music critics. Background and composition The band signed to a major label and received "all the ability that gives you when it comes to writing and recording", according to vocalist Mikey Chapman. Despite having waited a year before releasing ''Signals'', the group did not write any new material. When the band began writing new compositions they were stuck writing unsatisfactory material for a few months. Eventually, the group "got into this rhythm", according to bassist Sam Douglas and wrote the album in a month. A few parts that did not make it on to ''Signals'' was used f ...

Asymmetry (Karnivool Album)
''Asymmetry'' is the third studio album by Australian progressive rock band Karnivool. It is their first release in over four years, since ''Sound Awake'' (2009). It was released on 19 July 2013. The album's first single, "We Are", was released, along with an accompanying music video, released on 14 June 2013. At the J Awards of 2013, the album was nominated for Australian Album of the Year. Background After extensive worldwide touring in support of their second album, ''Sound Awake'', Karnivool took a break in 2010 so that lead vocals, vocalist Ian Kenny could work with his other band, Birds of Tokyo. The band would reconvene in 2011, when they would alternate between working on writing new music and performing on their "Melodias Frescas" tour through Australia. The band wrote the album over a two-year span, and then recorded it over a three-month span. The band worked with American music producer Nick DiDia. Drew Goddard said about the album title: "''Asymmetry'' to me is abou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymmetry (population Ethics)
The Asymmetry, also known as the Procreation Asymmetry, is the idea in population ethics that there is a moral or evaluative asymmetry between bringing into existence individuals with good or bad lives. It was first discussed by Jan Narveson in 1967, and Jeff McMahan coined the term 'the Asymmetry' in 1981. McMahan formulates the Asymmetry as follows: "while the fact that a person's life would be worse than no life at all ... constitutes a strong moral reason for not bringing him into existence, the fact that a person's life would be worth living provides no (or only a relatively weak) moral reason for bringing him into existence." Professor Nils Holtug formulates the Asymmetry evaluatively in terms of the value of outcomes instead of in terms of moral reasons. Holtug's formulation says that "while it detracts from the value of an outcome to add individuals whose lives are of overall negative value, it does not increase the value of an outcome to add individuals whose lives are o ...
