Pseudo Gene Schematic
The prefix pseudo- (from Greek ψευδής, ''pseudes'', "false") is used to mark something that superficially appears to be (or behaves like) one thing, but is something else. Subject to context, ''pseudo'' may connote coincidence, imitation, intentional deception, or a combination thereof. * In scholarship and studies, pseudo-scholarship refers to material that is presented as, but is not, the product of rigorous and objective study or research. Examples: **Pseudoarchaeology ** Pseudohistory ** Pseudolinguistics *** Pseudoscientific language comparison *** Folk linguistics ** Pseudomathematics ** Pseudophilosophy ** Pseudonym ** Pseudoscience **Pseudoculture * In biology and botany, the prefix 'pseudo' is used to indicate a species with a coincidental visual similarity to another genus. For example, ''Iris pseudacorus'' is known as '''pseud''acorus' for having leaves similar to those of ''Acorus calamus''. In biology, coincidental similarity is not the same as mimicry. * In l ...

Prefix
A prefix is an affix which is placed before the Word stem, stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix ''un-'' is added to the word ''happy'', it creates the word ''unhappy''. Particularly in the study of languages, a prefix is also called a preformative, because it alters the form of the words to which it is affixed. Prefixes, like other affixes, can be either inflectional, creating a new form of the word with the same basic meaning and same part of speech, lexical category (but playing a different role in the sentence), or Morphological derivation, derivational, creating a new word with a new semantics, semantic meaning and sometimes also a different Part of speech, lexical category. Prefixes, like all other affixes, are usually Bound and unbound morphemes, bound morphemes. In English language, English, there are no inflectional prefixes; English uses suffixes instead for that purpose. The word ''prefix'' ...

Pseudepigrapha
Pseudepigrapha (also anglicized as "pseudepigraph" or "pseudepigraphs") are falsely attributed works, texts whose claimed author is not the true author, or a work whose real author attributed it to a figure of the past.Bauckham, Richard; "Pseudo-Apostolic Letters", ''Journal of Biblical Literature'', Vo. 107, No. 3, September 1988, pp. 469–94. In biblical studies, the term ''pseudepigrapha'' can refer to an assorted collection of Jewish religious works thought to be written 300 BCE to 300 CE. They are distinguished by Protestants from the deuterocanonical books (Catholic and Orthodox) or Apocrypha (Protestant), the books that appear in extant copies of the Septuagint in the fourth century or later and the Vulgate, but not in the Hebrew Bible or in Protestant Bibles. The Catholic Church distinguishes only between the deuterocanonical and all other books; the latter are called biblical apocrypha, which in Catholic usage includes the pseudepigrapha. In addition, two books cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoachondroplasia
Pseudoachondroplasia is an inherited disorder of bone growth. It is a genetic autosomal dominant disorder. It is generally not discovered until 2–3 years of age, since growth is normal at first. Pseudoachondroplasia is usually first detected by a drop of linear growth in contrast to peers, a waddling gait or arising lower limb deformities. Pseudoachondroplasia (also known as PSACH, pseudoachondroplastic dysplasia, and pseudoachondroplastic spondyloepiphyseal dysplasia syndrome) is an osteochondrodysplasia that results in mild to severely short stature due to the inhibition of skeletal growth primarily in the limbs. Though similarities in nomenclature may cause confusion, pseudoachondroplasia should not be confused with achondroplasia, which is a clinically and genetically distinct skeletal dysplasia. Pseudoachondroplasia is caused by a heterozygous mutation in the gene encoding cartilage oligomeric matrix protein (COMP). Mutation in the COMP gene can also cause multiple epiph ...

Pseudoprime
A pseudoprime is a probable prime (an integer that shares a property common to all prime numbers) that is not actually prime. Pseudoprimes are classified according to which property of primes they satisfy. Some sources use the term pseudoprime to describe all probable primes, both composite numbers and actual primes. Pseudoprimes are of primary importance in public-key cryptography, which makes use of the difficulty of factoring large numbers into their prime factors. Carl Pomerance estimated in 1988 that it would cost $10 million to factor a number with 144 digits, and $100 billion to factor a 200-digit number (the cost today is dramatically lower but still prohibitively high). But finding two large prime numbers as needed for this use is also expensive, so various probabilistic primality tests are used, some of which in rare cases inappropriately deliver composite numbers instead of primes. On the other hand, deterministic primality tests, such as the AKS primality test, do not g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudorandomness
A pseudorandom sequence of numbers is one that appears to be statistically random, despite having been produced by a completely deterministic and repeatable process. Background The generation of random numbers has many uses, such as for random sampling, Monte Carlo methods, board games, or gambling. In physics, however, most processes, such as gravitational acceleration, are deterministic, meaning that they always produce the same outcome from the same starting point. Some notable exceptions are radioactive decay and quantum measurement, which are both modeled as being truly random processes in the underlying physics. Since these processes are not practical sources of random numbers, people use pseudorandom numbers, which ideally have the unpredictability of a truly random sequence, despite being generated by a deterministic process. In many applications, the deterministic process is a computer algorithm called a pseudorandom number generator, which must first be provided wi ...

Pseudo-arc
In general topology, the pseudo-arc is the simplest nondegenerate hereditarily indecomposable continuum. The pseudo-arc is an arc-like homogeneous continuum, and played a central role in the classification of homogeneous planar continua. R. H. Bing proved that, in a certain well-defined sense, most continua in R''n'', ''n'' ≥ 2, are homeomorphic to the pseudo-arc. History In 1920, Bronisław Knaster and Kazimierz Kuratowski asked whether a nondegenerate homogeneous continuum in the Euclidean plane R2 must be a Jordan curve. In 1921, Stefan Mazurkiewicz asked whether a nondegenerate continuum in R2 that is homeomorphic to each of its nondegenerate subcontinua must be an arc. In 1922, Knaster discovered the first example of a hereditarily indecomposable continuum ''K'', later named the pseudo-arc, giving a negative answer to a Mazurkiewicz question. In 1948, R. H. Bing proved that Knaster's continuum is homogeneous, i.e. for any two of its points there is a homeomorphism takin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudo-atoll
A pseudo-atoll, like an atoll, is an island that encircles a lagoon, either partially or completely. A pseudo-atoll differs from an atoll as established by several authorities, such as how it is formed (not by subsidence, nor by coral). It is considered a preferable term to "near-atoll". There is a need for rigorous definition of "pseudo-atoll" before it can be accepted as a general term. Definitions Alexander Agassiz gave the term pseudo-atoll to "any ring-shaped reefs not formed as a result of subsidence". while Norman D. Newell and J. Keith Rigby called such reefs non-coral. and "We conclude that almost-atoll should be retained as a descriptive term as defined by Davis and Tayama, and that the use of "near-atoll" as a synonym be abandoned. The value of terms such as "semi-atoll" and "pseudo-atoll" needs close examination and more rigorous definition before being generally accepted." H. Mergner yet states that micro-atolls classify as pseudo-atolls. Professor David R. Stoddart of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pseudo-Chalkidian Vase Painting
Pseudo-Chalcidian vase painting is an important style of black-figure Greek vase painting, dating to the 6th century BC. Pseudo-Chalcidian vase painting was strongly influenced by Chalcidian vase painting, but also shows influences from Attic and Corinthian vase painting. The potters used the Ionic alphabet (and not the Chalcidian one) for added inscriptions. The clays were of a different fabric from those used for Chalcidian pottery. By now, about 60 vases of the style are known (they were compiled for the first time by Andreas Rumpf). The potters/painters may have been the successors of those who produced Chalcidian pottery, as well as some potters newly immigrated to Etruria. Pseudo-Chalcidian vase painting can be subdivided in two groups. The older of the two is the Polyphemus Group. It produced the majority of known vases, mainly neck amphorae and '' oinochoai''. Most show groups of animals, mythological imagery is rare (Herakles, Hephaistos). The vessels were found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudo-Cyrillic
Faux Cyrillic, pseudo-Cyrillic, pseudo-Russian or faux Russian typography is the use of Cyrillic letters in Latin text, usually to evoke the Soviet Union or Russia, though it may be used in other contexts as well. It is a common Western trope used in book covers, film titles, comic book lettering, artwork for computer games, or product packaging which are set in or wish to evoke Eastern Europe, the Soviet Union, or Russia. A typeface designed to emulate Cyrillic is classed as an ethnic typeface. Letters are substituted regardless of phonetic matching. For example, ''R'' and ''N'' in ''RUSSIAN'' may be replaced with Cyrillic Я ("ya") and И ("i") to form the faux-cyrillic "ЯUSSIAИ" . Other examples include the use of Ш for W, Ц for U, Я/ Г for R/backwards and upside-down L, Ф for O, Д for A, Б, Ь, or Ъ for B/b, З, Э, or Ё for E, Ч or У for Y. Outside the Russian alphabet, Џ (from Serbian) can act as a substitute for U, Ғ (from Turkic languag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudo-Kufic
Pseudo-Kufic, or Kufesque, also sometimes Pseudo-Arabic, is a style of decoration used during the Middle Ages and the Renaissance,Encyclopaedia BritannicaBeautiful Gibberish: Fake Arabic in Medieval and Renaissance Art/ref> consisting of imitations of the Arabic Kufic script, or sometimes Arabic cursive script, made in a non-Arabic context: "Imitations of Arabic in European art are often described as pseudo-Kufic, borrowing the term for an Arabic script that emphasizes straight and angular strokes, and is most commonly used in Islamic architectural decoration".Mack, p.51 Pseudo-Kufic appears especially often in Renaissance art in depictions of people from the Holy Land, particularly the Virgin Mary. It is an example of Islamic influences on Western art. Early examples Some of the first imitations of the Kufic script go back to the 8th century when the English King Offa (r. 757–796) produced gold coins imitating Islamic dinars. These coins were copies of an Abbasid dinar struck ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoephedrine
Pseudoephedrine (PSE) is a sympathomimetic drug of the phenethylamine and amphetamine chemical classes. It may be used as a nasal/sinus decongestant, as a stimulant, or as a wakefulness-promoting agent in higher doses. It was first characterized in 1889 by the German chemists Ladenburg and Oelschlägel, who used a sample that had been isolated from ''Ephedra vulgaris'' by the Merck pharmaceutical corporation of Darmstadt, Germany. The salts pseudoephedrine hydrochloride and pseudoephedrine sulfate are found in many over-the-counter preparations, either as a single ingredient or (more commonly) in a fixed-dose combination with one or more additional active ingredients such as antihistamines, guaifenesin, dextromethorphan, paracetamol (acetaminophen) or an NSAID (such as aspirin or ibuprofen). Medical uses Pseudoephedrine is a stimulant, but it is well known for shrinking swollen nasal mucous membranes, so it is often used as a decongestant. It reduces tissue hyperemia, ede ...
