Current (mathematics)

In mathematics, more particularly in functional analysis, differential topology, and geometric measure theory, a k-current in the sense of Georges de Rham is a functional on the space of compactly supported differential k-forms, on a smooth manifold M. Formally currents behave like Schwartz distributions on a space of differential forms. In a geometric setting, they can represent integration over a submanifold, generalizing the Dirac delta function, or more generally even directional derivatives of delta functions (multipoles) spread out along subsets of M.

Definition

Let denote the space of smooth m-forms with compact support on a smooth manifold . A current is a linear functional on which is continuous in the sense of distributions. Thus a linear functional

is an m-current if it is continuous in the following sense: If a sequence of smooth forms, all supported in the same compact set, is such that all derivatives of all their coefficients tend uniformly to 0 when tends to infinity, then tends to 0.

Leech

Leeches are segmented worms that belong to the phylum Annelida and comprise the subclass Hirudinea. Like the oligochaetes, such as earthworms, leeches share a clitellum and are hermaphrodites. Nevertheless, they differ from the oligochaetes in significant ways. For example, leeches do not have bristles and the external segmentation of their bodies does not correspond with the internal segmentation of their organs. Their bodies are much more solid as the spaces in their coelom are dense with connective tissues. They also have two suckers, one at each end.

The majority of leeches live in freshwater environments, while some species can be found in terrestrial and marine environments, as well. The best-known leeches, such as the medicinal leech, Hirudo medicinalis, are hematophagous, feeding on vertebrate blood and invertebrate hemolymph. Most leech species, however, are predatory, feeding primarily by swallowing other invertebrates. Almost 700 species of leeches are currently recognized, of which some 100 are marine, 90 terrestrial and the remainder freshwater taxa.

Leech (computing)

In computing and specifically Internet, a leech is one who benefits, usually deliberately, from others' information or effort but does not offer anything in return, or makes only token offerings in an attempt to avoid being called a leech. In economics, this type of behavior is called "free riding" and is associated with the free rider problem.

Depending on context, leeching does not necessarily refer to illegal use of computer resources, but often instead to greedy use according to etiquette: to wit, using too much of what is freely given without contributing a reasonable amount back to the community that provides it.

The name derives from the leech, an animal that sucks blood and then tries to leave unnoticed. Other terms are used, such as "freeloader" and "sponge", but leech is the most common.

List of She-Ra: Princess of Power characters

This is a list of She-Ra: Princess of Power characters.

The Great Rebellion

She-Ra

She-Ra is introduced in the animated movie The Secret of the Sword as Force Captain Adora, who was an agent of the Evil Horde that rules the planet Etheria. She discovers that she is the long-lost twin sister of Prince Adam of Eternia, having been stolen by the Horde's leader, Hordak, as a baby. She is granted the Sword of Protection, which parallels He-Man's Sword of Power, gaining the power to transform into She-Ra, her secret identity.

She-Ra and Princess Adora are voiced by Melendy Britt in the 80s series.

Swift Wind

Spirit is the horse of Adora. When she transforms into She-Ra he also transforms into Swift Wind. He has a mate named Starwind and they have a young colt. Unlike Cringer, who turns into Battle Cat (In He-man series), Spirit's size doesn't change, but he gets wings, and has a unicorn like horn.

Spirit/Swift Wind are voiced by Lou Scheimer in the 80s series.
