Labdia irrigua is a moth in the family Cosmopterigidae. It was described by Edward Meyrick in 1915. It is known from Australia. [1]
In mathematics, convolution is a mathematical operation on two functions that produces a third function. The term convolution refers to both the result function and to the process of computing it. It is defined as the integral of the product of the two functions after one is reflected about the y-axis and shifted. The integral is evaluated for all values of shift, producing the convolution function. The choice of which function is reflected and shifted before the integral does not change the integral result. Graphically, it expresses how the 'shape' of one function is modified by the other.
In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion.
Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, Edmund Landau, and others, collectively called Bachmann–Landau notation or asymptotic notation. The letter O was chosen by Bachmann to stand for Ordnung, meaning the order of approximation.
In physics, engineering and mathematics, the Fourier transform (FT) is an integral transform that converts a function into a form that describes the frequencies present in the original function. The output of the transform is a complex-valued function of frequency. The term Fourier transform refers to both this complex-valued function and the mathematical operation. When a distinction needs to be made the Fourier transform is sometimes called the frequency domain representation of the original function. The Fourier transform is analogous to decomposing the sound of a musical chord into the intensities of its constituent pitches.
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
In thermodynamics, the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum amount of work, other than pressure-volume work, that may be performed by a thermodynamically closed system at constant temperature and pressure. It also provides a necessary condition for processes such as chemical reactions that may occur under these conditions. The Gibbs free energy is expressed as
Time dilation is the difference in elapsed time as measured by two clocks, either due to a relative velocity between them, or a difference in gravitational potential between their locations. When unspecified, "time dilation" usually refers to the effect due to velocity.
Stellaria is a genus of about 190 species of flowering plants in the family Caryophyllaceae, with a cosmopolitan distribution. Common names include starwort, stitchwort and chickweed.
Aphaenogaster is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species. They occur worldwide except in South America south of Colombia, sub-Saharan Africa, and Antarctica.
Leiostyla is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Lauriidae.
Streptostyla is a genus of predatory, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Streptostylinae of the family Spiraxidae.
Scapania is a genus of liverworts in the family Scapaniaceae. It contains the following species :
The Circumboreal Region in phytogeography is a floristic region within the Holarctic Kingdom in Eurasia and North America, as delineated by such geobotanists as Josias Braun-Blanquet and Armen Takhtajan.
Carex magellanica subsp. irrigua is a perennial species of plants in the family Cyperaceae native to Holarctic wetlands. Common names include poor sedge, bog sedge and boreal bog sedge.
Bog sedge is a vernacular name for any of the following plants:
Porpidia is a genus of crustose lichens in the family Lecideaceae.
Stellaria irrigua is a species of flowering plant in the family Caryophyllaceae known by the common names umbrella starwort and umbellate starwort. It is native to western North America from Alaska and north-western Canada to the south-western United States, as well as parts of Asia, including Siberia. It grows in subalpine and alpine climates in mountain forests and riverbanks. It is a rhizomatous perennial herb producing a slender prostrate stem up to about 20 centimeters long, sometimes forming clumps or mats. The stem is lined with pairs of oval leaves each up to about 2 centimeters long. The inflorescence is an umbel-shaped array of several flowers each on an arching or erect pedicels. The flower has five pointed green sepals each no more than 3 millimeters long. There are occasionally tiny white petals within the calyx of sepals, but these are generally absent.
Un fil à la patte is a three-act farce by Georges Feydeau. It was first performed in Paris in 1894 and ran for 129 performances. The play has been revived frequently in France, and has been staged in translations in the US and Britain.
Valiano is a frazione of the town of Montepulciano in the Province of Siena, on the border between the regions of Umbria and Tuscany. It was an ancient feudal castle which, due to its strategic position and the role played by the family of Del Pecora, was an outpost of Val di Chiana of great historical importance from thirteenth century until the establishment of Grand Duchy of Tuscany.
Bisboeckelera is a genus of flowering plants belonging to the family Cyperaceae.
