If a small area of the fractal is being drawn, many of these points will fall outside of the screen boundaries. This makes zooming into an IFS construction drawn in this manner impractical. Although the theory of IFS requires each function to be contractive, in practice software that implements IFS only require that the whole system be contractive on average.

Furthermore, as dilative soil grains dilate, they become looser (their void ratio increases), and their rate of dilation decreases until they reach a critical void ratio. Contractive soils become denser as they shear, and their rate of contraction decreases until they reach a critical void ratio. A critical state line separates the dilatant and contractive states for soil The tendency for a soil to dilate or contract depends primarily on the confining pressure and the void ratio of the soil. The rate of dilation is high if the confining pressure is small and the void ratio is small.

The smooth muscular layer within the vagina has a weak contractive force that can create some pressure in the lumen of the vagina; much stronger contractive force, such as during childbirth, comes from muscles in the pelvic floor that are attached to the adventitia around the vagina. The lamina propria is rich in blood vessels and lymphatic channels. The muscular layer is composed of smooth muscle fibers, with an outer layer of longitudinal muscle, an inner layer of circular muscle, and oblique muscle fibers between. The outer layer, the adventitia, is a thin dense layer of connective tissue and it blends with loose connective tissue containing blood vessels, lymphatic vessels and nerve fibers that are between pelvic organs.

According to him the living cells in the inner lining of the xylem tissue pump water by contractive and expulsive movements similar to the animal heart circulating blood. This mechanism has not been well supported, and in spite of some ongoing debate, the evidence overwhelmingly supports the cohesion-tension theory for the ascent of sap.

A radial arrangement involves fibers radiating out in all directions from the center of the organ. This is found in the tentacles of the chambered nautilus and in the elephant proboscis (trunk). A circular arrangement has rings of contractive fibers around the long axis. This is found in many mammalian and lizard tongues along with squid tentacles.

From the effective stress equation, the change in u directly effects the effective stress by the equation: :\sigma' = \sigma - u\, and the strength is very sensitive to the effective stress. It follows then that the undrained shear strength of a soil may be smaller or larger than the drained shear strength depending upon whether the soil is contractive or dilative.

Clinicians have recommended that extra contraceptive measures be applied during therapies using antibiotics that are suspected to interact with oral contraceptives. More studies on the possible interactions between antibiotics and birth control pills (oral contraceptives) are required as well as careful assessment of patient-specific risk factors for potential oral contractive pill failure prior to dismissing the need for backup contraception.

On the other hand, when a granular material starts in a very loose state it may continuously compact instead of dilating under shear. A sample of a material is called dilative if its volume increases with increasing shear and contractive if the volume decreases with increasing shear.Casagrande, A., Hirschfeld, R. C., & Poulos, S. J. (1964). Fourth Report: Investigation of Stress-Deformation and Strength Characteristics of Compacted Clays.

Hutchinson showed in 1981 the existence and uniqueness of the attractor A. The proof follows by showing that the Hutchinson operator is contractive on the set of compact subsets of X in the Hausdorff distance. The collection of functions f_i together with composition form a monoid. With N functions, then one may visualize the monoid as a full N-ary tree or a Cayley tree.

More generally, the idea of a contractive mapping can be defined for maps between metric spaces. Thus, if (M, d) and (N, d') are two metric spaces, then f:M \rightarrow N is a contractive mapping if there is a constant 0 \leq k < 1 such that :d'(f(x),f(y)) \leq k\,d(x,y) for all x and y in M. Every contraction mapping is Lipschitz continuous and hence uniformly continuous (for a Lipschitz continuous function, the constant k is no longer necessarily less than 1). A contraction mapping has at most one fixed point. Moreover, the Banach fixed-point theorem states that every contraction mapping on a non-empty complete metric space has a unique fixed point, and that for any x in M the iterated function sequence x, f (x), f (f (x)), f (f (f (x))), ... converges to the fixed point.

IFS fractals, as they are normally called, can be of any number of dimensions, but are commonly computed and drawn in 2D. The fractal is made up of the union of several copies of itself, each copy being transformed by a function (hence "function system"). The canonical example is the Sierpiński triangle. The functions are normally contractive, which means they bring points closer together and make shapes smaller.

Human liquor means waste content from bowels isolated to investigate specific enzymes and peptidases involved in enteric contraction and digestion of compounds. P-endopeptidase isolated from human liquor inactivates tachykinins. Hydrolysis of Substance P by P-endopeptidase yields the active fragment of substance P. A neuroactive peptide, Substance P is found throughout the central and peripheral nervous system. It has mostly been studied for its contractive effect on enteric musculature.

In mathematics, the Littlewood subordination theorem, proved by J. E. Littlewood in 1925, is a theorem in operator theory and complex analysis. It states that any holomorphic univalent self-mapping of the unit disk in the complex numbers that fixes 0 induces a contractive composition operator on various function spaces of holomorphic functions on the disk. These spaces include the Hardy spaces, the Bergman spaces and Dirichlet space.

When their activity is waxing (rapid or expansive), that is the yang energy mode. When their activity is waning (slow or contractive), that is the yin energy mode. The yang and yin phases constantly interact, each gaining and losing dominance over the other. In the process of the waxing and waning, the alternation of these fundamental vibrations, the so-called five elements (fire, water, wood, metal, and earth) evolve.

Several converses of the Banach contraction principle exist. The following is due to Czesław Bessaga, from 1959: Let f : X → X be a map of an abstract set such that each iterate fn has a unique fixed point. Let q ∈ (0, 1), then there exists a complete metric on X such that f is contractive, and q is the contraction constant. Indeed, very weak assumptions suffice to obtain such a kind of converse.

Continuous transformation pausing at the vertex position of Jessen's icosahedron Jessen's icosahedron is one of a continuous series of icosahedra with 8 regular faces and 12 isosceles faces, described by H. S. M. Coxeter in 1948. The shapes in this family range from cuboctahedron to regular octahedron (as limit cases), which can be inscribed in a regular octahedron. The twisting, expansive-contractive transformations between members of this family were named Jitterbug transformations by Buckminster Fuller.

The original ekpyrotic model was introduced by Justin Khoury, Burt Ovrut, Paul Steinhardt and Neil Turok in 2001. Steinhardt created the name based on the early word ekpyrosis (Ancient Greek: ἐκπύρωσις, ekpyrōsis, "conflagration"); it refers to an ancient Stoic cosmological model in which the universe is caught in an eternal cycle of fiery birth, cooling and rebirth.'The dissolution of the universe into fire'. In Stoic philosophy, ekpyrosis, all-engulfing cosmic fire, represents the contractive phase of eternally-recurring destruction and re-creation.

Action potentials are considerably different between conductive and contractive cardiomyocytes. While sodium Na+ and potassium K+ ions play essential roles, calcium ions Ca2+ are also critical for both types of cell. Unlike skeletal muscles and neurons, cardiac conductive cells do not have a stable resting potential. Conductive cells contain a series of sodium ion channels that allow a normal and slow influx of sodium ions that causes the membrane potential to rise slowly from an initial value of −60 mV up to about –40 mV.

A soil which is currently experiencing the maximum past vertical effective stress is said to be normally consolidated. The overconsolidation ratio, (OCR) is the ratio of the maximum past vertical effective stress to the current vertical effective stress. The OCR is significant for two reasons: firstly, because the compressibility of normally consolidated soil is significantly larger than that for overconsolidated soil, and secondly, the shear behavior and dilatancy of clayey soil are related to the OCR through critical state soil mechanics; highly overconsolidated clayey soils are dilatant, while normally consolidated soils tend to be contractive.

The stress- strain relationship of soils, and therefore the shearing strength, is affected by: # soil composition (basic soil material): mineralogy, grain size and grain size distribution, shape of particles, pore fluid type and content, ions on grain and in pore fluid. # state (initial): Defined by the initial void ratio, effective normal stress and shear stress (stress history). State can be described by terms such as: loose, dense, overconsolidated, normally consolidated, stiff, soft, contractive, dilative, etc. # structure: Refers to the arrangement of particles within the soil mass; the manner the particles are packed or distributed.

Clave resolves in the second measure when the last stroke coincides with the last main beat of the cycle.Emilio Grenet: "[The] melodic design is constructed on a rhythmic pattern of two measures, as though both were only one, the first is antecedent, strong, and the second is consequent, weak." 1939 p. XV. John Amria describes the rhythmic sequence of clave: > [With] clave ... the two measures are not at odds, but rather, they are > balanced opposites like positive and negative, expansive and contractive or > the poles of a magnet.

Schelling held that the divisions imposed on nature, by our ordinary perception and thought, do not have absolute validity. They should be interpreted as the outcome of the single formative energy which is the soul or inner aspect of nature. In other words he was a proponent of a variety of organicism. The dynamic series of stages in nature, the forms in which the ideal structure of nature is realized, are matter, as the equilibrium of the fundamental expansive and contractive forces; light, with its subordinate processes (magnetism, electricity, and chemical action); organism, with its component phases of reproduction, irritability and sensibility.

In mathematics, a contraction mapping, or contraction or contractor, on a metric space (M, d) is a function f from M to itself, with the property that there is some nonnegative real number 0 \leq k < 1 such that for all x and y in M, :d(f(x),f(y)) \leq k\,d(x,y). The smallest such value of k is called the Lipschitz constant of f. Contractive maps are sometimes called Lipschitzian maps. If the above condition is instead satisfied for k ≤ 1, then the mapping is said to be a non-expansive map.

In part this stems from the biblical injunction against Onanism, but she also felt a failure of magnetic interchange was injurious and unnatural. Thus she advocated "the Oneida method" (from the Oneida Society), then also known as "male continence", in which men refrained from ejaculation but women were encouraged to have contractive orgasms at will. In later writings she also began to promulgate the need for women to learn to control their orgasm responses in the same way that the men of Oneida did. Ultimately, Stockham rejected the "male continence" techniques of John Humphrey Noyes in favour of gender parity in orgasm control.

In mathematics, the Banach–Caccioppoli fixed-point theorem (also known as the contraction mapping theorem or contractive mapping theorem) is an important tool in the theory of metric spaces; it guarantees the existence and uniqueness of fixed points of certain self-maps of metric spaces, and provides a constructive method to find those fixed points. It can be understood as an abstract formulation of Picard's method of successive approximations. The theorem is named after Stefan Banach (1892–1945) and Renato Caccioppoli (1904–1959), and was first stated by Banach in 1922. Caccioppoli independently proved the theorem in 1931.

A new district was created using the name Union-Scioto Rural School. The school became known as “Unioto”, a contractive term taken from Union and Scioto. A tax levy of 3 ½ mils voted by the district evolved the sum of $50,000 which was matched by another $50,000 from the Federal government under the Public Works Administration and numbered as Project M OH 1021 R. The building site was purchased from Mr. George Garrison, on Egypt Pike, for the sum of $2,000. Construction was started in February 1936, and the building was occupied September 23 of the same year.

If the grains are densely packed, the grains tend to spread apart from each other as they are subject to shear strain. The expansion of the particle matrix due to shearing was called dilatancy by Osborne Reynolds. If one considers the energy required to shear an assembly of particles there is energy input by the shear force, T, moving a distance, x and there is also energy input by the normal force, N, as the sample expands a distance, y. Due to the extra energy required for the particles to dilate against the confining pressures, dilatant soils have a greater peak strength than contractive soils.

Similarly, for contractive soil, water must be squeezed out of the pore spaces to allow contraction to take place. Dilation of the voids causes negative water pressures that draw fluid into the pores, and contraction of the voids causes positive pore pressures to push the water out of the pores. If the rate of shearing is very large compared to the rate that water can be sucked into or squeezed out of the dilating or contracting pore spaces, then the shearing is called undrained shear, if the shearing is slow enough that the water pressures are negligible, the shearing is called drained shear. During undrained shear, the water pressure u changes depending on volume change tendencies.

The stress-strain relationship levels off when the material stops expanding or contracting, and when interparticle bonds are broken. The theoretical state at which the shear stress and density remain constant while the shear strain increases may be called the critical state, steady state, or residual strength. A critical state line separates the dilatant and contractive states for soil The volume change behavior and interparticle friction depend on the density of the particles, the intergranular contact forces, and to a somewhat lesser extent, other factors such as the rate of shearing and the direction of the shear stress. The average normal intergranular contact force per unit area is called the effective stress.

The published studies were designed to definitively answer whether the power-posing hypothesis was real and included high quality research features like pre-registration of endpoints. Carney co-authored the introduction to the issue, and noted that while the meta-analysis failed to find any effect in power behaviors, it did find a small effect in a feeling of power; she also wrote that the studies could not resolve whether the effect on a feeling of power was only an experimental artifact. In a 2019 review of all prior power posing research Marcus Crede, an Associate Professor of Psychology at Iowa State University noted that no study had ever found that power poses resulted in higher feelings of power than a normal pose. Crede noted that almost all prior research had only compared power poses to contractive poses like slouching but had failed to include a normal pose as a control group.

In 1711 he published 'A Demonstration of the Truth and Divinity of the Christian Religion,' and in the following year 'The Principles of Natural Philosophy, in which is shown the insufficiency of the present systems to give us any just account of that science.' The latter work was ridiculed and parodied in 'A Taste of Philosophical Fanaticism ... by a gentleman of the University of Gratz.' Greene, while taking an active part in college and parochial work, was convinced that the whole field of knowledge was his proper province, and devoted many years' leisure to the production of his next work, a large folio volume of 980 pages, entitled 'The Principles of the Philosophy of the Expansive and Contractive Forces, or an Enquiry into the Principles of the Modern Philosophy, that is, into the several chief Rational Sciences which are extant,' 1727. In the preface Greene, after being at some pains to prove himself a whig, declared his intention of proposing a philosophy, English, Cantabrigian, and Clarensian, which he ventured to call the 'Greenian,' because his name was 'not much worse in the letters which belonged to it than those of Galileo and Descartes.
