Munro
A Munro () is defined as a mountain in Scotland with a height over , and which is on the Scottish Mountaineering Club (SMC) official list of Munros; there is no explicit topographical prominence requirement. The best known Munro is Ben Nevis (Beinn Nibheis), the highest mountain in the British Isles at . Munros are named after Sir Hugh Munro, 4th Baronet (1856–1919), who produced the first list of such hills, known as ''Munro's Tables'', in 1891. Also included were what Munro considered lesser peaks, now known as Munro Tops, which are also over 3,000 feet but are lower than the nearby primary mountain. The publication of the original list is usually considered to be the epoch event of modern peak bagging. The list has been the subject of subsequent variation and as of 10 December 2020, the Scottish Mountaineering Club has listed 282 Munros and 226 Munro Tops. "Munro bagging" is the activity of climbing all the listed Munros. As of 31 December 2021, 7,098 people had reported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Top Quark
The top quark, sometimes also referred to as the truth quark, (symbol: t) is the most massive of all observed elementary particles. It derives its mass from its coupling to the Higgs Boson. This coupling y_ is very close to unity; in the Standard Model of particle physics, it is the largest (strongest) coupling at the scale of the weak interactions and above. The top quark was discovered in 1995 by the CDF and DØ experiments at Fermilab. Like all other quarks, the top quark is a fermion with spin and participates in all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions. It has an electric charge of + ''e''. It has a mass of , which is close to the rhenium atom mass. The antiparticle of the top quark is the top antiquark (symbol: , sometimes called ''antitop quark'' or simply ''antitop''), which differs from it only in that some of its properties have equal magnitude but opposite sign. The top quark interacts with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tee (symbol)
The tee (⊤, \top in LaTeX) also called down tack (as opposed to the up tack) or verum is a symbol used to represent: * The top element in lattice theory. * The truth value of being true in logic, or a sentence (e.g., formula in propositional calculus) which is unconditionally true. By definition, every tautology is logically equivalent to the verum. * The top type in type theory. * Mixed radix encoding in the APL programming language. A similar-looking superscript T may be used to mean the transpose of a matrix. Encoding In Unicode, the tee character is encoded as . The symbol is encoded in LaTeX as \top. A large variant is encoded as in the Unicode block Miscellaneous Mathematical Symbols-A. See also * Turnstile (⊢) * Up tack (⊥) *Falsum The up tack or falsum (⊥, \bot in LaTeX, U+22A5 in Unicode) is a constant symbol used to represent: * The truth value 'false', or a logical constant denoting a proposition in logic that is always false (often called ...

Top (mathematical Logic)
In mathematical logic and computer science, some type theories and type systems include a top type that is commonly denoted with top or the symbol ⊤. The top type is sometimes called also ''universal type'', or ''universal supertype'' as all other types in the type system of interest are subtypes of it, and in most cases, it contains every possible object of the type system. It is in contrast with the bottom type, or the ''universal subtype'', which every other type is supertype of and it is often that the type contains no members at all. Support in programming languages Several typed programming languages provide explicit support for the top type. In statically-typed languages, there are two different, often confused, concepts when discussing the top type. # A ''universal base class'' or other item at the top of a run time ''class hierarchy'' (often relevant in object-oriented programming) or ''type hierarchy''; it is often possible to create objects with this (run time ...

Greatest Element
In mathematics, especially in order theory, the greatest element of a subset S of a partially ordered set (poset) is an element of S that is greater than every other element of S. The term least element is defined dually, that is, it is an element of S that is smaller than every other element of S. Definitions Let (P, \leq) be a preordered set and let S \subseteq P. An element g \in P is said to be if g \in S and if it also satisfies: :s \leq g for all s \in S. By using \,\geq\, instead of \,\leq\, in the above definition, the definition of a least element of S is obtained. Explicitly, an element l \in P is said to be if l \in S and if it also satisfies: :l \leq s for all s \in S. If (P, \leq) is even a partially ordered set then S can have at most one greatest element and it can have at most one least element. Whenever a greatest element of S exists and is unique then this element is called greatest element of S. The terminology least element of S is defined simila ...

Top (algebra)
In the context of a module ''M'' over a ring ''R'', the top of ''M'' is the largest semisimple quotient module of ''M'' if it exists. For finite-dimensional ''k''-algebras (''k'' a field) R, if rad(''M'') denotes the intersection of all proper maximal submodules of ''M'' (the radical of the module), then the top of ''M'' is ''M''/rad(''M''). In the case of local rings with maximal ideal ''P'', the top of ''M'' is ''M''/''PM''. In general if ''R'' is a semilocal ring (=semi-artinian ring), that is, if ''R''/Rad(''R'') is an Artinian ring, where Rad(''R'') is the Jacobson radical of ''R'', then ''M''/rad(''M'') is a semisimple module and is the top of ''M''. This includes the cases of local rings and finite dimensional algebras over fields. See also * Projective cover *Radical of a module *Socle (mathematics) In mathematics, the term socle has several related meanings. Socle of a group In the context of group theory, the socle of a group ''G'', denoted soc(''G''), is the subgro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Top (category Theory)
In mathematics, the category of topological spaces, often denoted Top, is the category whose objects are topological spaces and whose morphisms are continuous maps. This is a category because the composition of two continuous maps is again continuous, and the identity function is continuous. The study of Top and of properties of topological spaces using the techniques of category theory is known as categorical topology. N.B. Some authors use the name Top for the categories with topological manifolds, with compactly generated spaces as objects and continuous maps as morphisms or with the category of compactly generated weak Hausdorff spaces. As a concrete category Like many categories, the category Top is a concrete category, meaning its objects are sets with additional structure (i.e. topologies) and its morphisms are functions preserving this structure. There is a natural forgetful functor :''U'' : Top → Set to the category of sets which assigns to each topological space ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stack (abstract Data Type)
In computer science, a stack is an abstract data type that serves as a collection of elements, with two main operations: * Push, which adds an element to the collection, and * Pop, which removes the most recently added element that was not yet removed. Additionally, a peek operation can, without modifying the stack, return the value of the last element added. Calling this structure a ''stack'' is by analogy to a set of physical items stacked one atop another, such as a stack of plates. The order in which an element added to or removed from a stack is described as last in, first out, referred to by the acronym LIFO. As with a stack of physical objects, this structure makes it easy to take an item off the top of the stack, but accessing a datum deeper in the stack may require taking off multiple other items first. Considered as a linear data structure, or more abstractly a sequential collection, the push and pop operations occur only at one end of the structure, referred to ...

Top Domain
A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet after the root domain. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last non empty label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is .com. Responsibility for management of most top-level domains is delegated to specific organizations by the ICANN, an Internet multi-stakeholder community, which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone. History Originally, the top-level domain space was organized into three main groups: ''Countries'', ''Categories'', and ''Multiorganizations''. An additional ''temporary'' group consisted of only the initial DNS domain, arpa, and was intended for transitional purposes toward ...

Top (software)
top (table of processes) is a task manager program, found in many Unix-like operating systems, that displays information about CPU and memory utilization. Overview The program produces an ordered list of running processes selected by user-specified criteria, and updates it periodically. Default ordering is by CPU usage, and only the top CPU consumers are shown. top shows how much processing power and memory are being used, as well as other information about the running processes. Some versions of top allow extensive customization of the display, such as choice of columns or sorting method. top is useful for system administrators, as it shows which users and processes are consuming the most system resources at any given time. Implementations There are several different versions of top. The traditional Unix version was written by William LeFebvre and originally copyrighted in 1984. It is hosted on SourceForge, and release 3.7 was announced in 2008. The Linux version of top is pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
