The vagina is an organ capable of remarkable contraction and dilation.

This is as a direct result of Gravitational time dilation ; frequency of the electromagnetic radiation is reduced in an area of a higher gravitational potential.

More generally, processes close to a massive body run more slowly when compared with processes taking place farther away ; this effect is known as gravitational time dilation.

Gravitational time dilation in the Earth's gravitational field has been measured numerous times using atomic clocks, while ongoing validation is provided as a side effect of the operation of the Global Positioning System ( GPS ).

Ultrasound is then used to see vascular dilation and measure penile blood pressure.

Larmor is also credited to have been the first to understand the crucial time dilation property inherent in his equations.

That resulted in the formulation of the so called Lorentz transformation by Joseph Larmor ( 1897, 1900 ) and Lorentz ( 1899, 1904 ), whereby it was noted by Larmor that the complete formulation of local time is accompanied by some sort of time dilation of moving electrons in the aether.

This difference in elapsed time is a form of curvature called gravitational time dilation.

Both magnetism lacking electricity, and electricity without magnetism, are inconsistent with special relativity, due to such effects as length contraction, time dilation, and the fact that the magnetic force is velocity-dependent.

Note that the following is a classical ( Newtonian ) analysis of orbital mechanics, which assumes that the more subtle effects of general relativity, such as frame dragging and gravitational time dilation are negligible.

* Since a ship traveling at impulse velocities ( slower than, but approaching, the speed of light ) is still traveling in the normal space-time continuum, concerns of time dilation apply, so high relativistic speeds are avoided unless absolutely necessary ; impulse power is therefore customarily limited to a maximum of ¼ lightspeed.

This theory has a wide range of consequences which have been experimentally verified, including counter-intuitive ones such as length contraction, time dilation and relativity of simultaneity, contradicting the classical notion that the duration of the time interval between two events is equal for all observers.

( Such slowing, called time dilation, is explained in special relativity theory.

This is called gravitational time dilation.

This is also the instant at which TAI introduced corrections for gravitational time dilation.

The present definition of TT is a linear scaling of Geocentric Coordinate Time ( TCG ), which is the proper time of a notional observer who is infinitely far away ( so not affected by gravitational time dilation ) and at rest relative to the Earth.

Although time travel has been a common plot device in science fiction since the late 19th century and the theories of special and general relativity allow methods for forms of one-way travel into the future via time dilation, it is currently unknown whether the laws of physics would allow time travel into the past.

A contravariant vector is required to have components that " transform like the coordinates " under changes of coordinates such as rotation and dilation.

time dilation would result in the accelerated wormhole mouth aging less than the stationary one as seen by an external observer, similar to what is seen in the twin paradox.

If this is so, conventional relativistic effects such as time dilation would not apply in the way they would in the case of a ship moving at a very great velocity through flat spacetime, relative to other objects.

One of the meanings of the terms similarity and similarity transformation ( also called dilation ) of a Euclidean space is a function f from the space into itself that multiplies all distances by the same positive scalar r, so that for any two points x and y we have

It is also possible to classify cardiomyopathies functionally, as involving dilation, hypertrophy, or restriction.

Finally, the dilation of the pupils was also exceedingly difficult to measure, as the change was often smaller than one millimeter.

That is, they reduce excitement / physical exertion on heart rate and force of contraction, and also tremor and breakdown of glycogen, but increase dilation of blood vessels and constriction of bronchi.

It also served as a test to indirectly verify time dilation – while the negative result of the Michelson – Morley experiment can be explained by length contraction alone, the negative result of the Kennedy – Thorndike experiment requires time dilation in addition to length contraction to explain why no phase shifts will be detected while the earth moves around the sun.

The above beta function, which describes the " running of the coupling " parameter with scale, was also found to amount to the " canonical trace anomaly ", which represents the quantum-mechanical breaking of scale ( dilation ) symmetry in a field theory.

Travel to regions of spacetime where gravitational time dilation is taking place, such as within the gravitational field of a black hole but outside the event horizon ( perhaps on a hyperbolic trajectory exiting the field ), could also yield results consistent with present theory.

In addition to the pulmonary circuit, Colombo also discovered that the main action of the heart was contraction, rather than dilation as had previously been thought.

This is also the instant at which TAI introduced corrections for gravitational time dilation.

This is also the instant at which TAI introduced corrections for gravitational time dilation.

When the Earth is at perihelion in January, TCG ticks even more slowly than it does on average, due to gravitational time dilation from being deeper in the Sun's gravity well and also velocity time dilation from moving faster relative to the Sun.

Consumption also has been known to cause pupil dilation when taken with certain antidepressants or SSRIs.

" He has also voted several times to ban the " intact dilation and evacuation " or " partial-birth abortion " procedure.

Many vasoconstrictors also cause pupil dilation.

Toxicology also manifests in the autonomic nervous system, causing urinary retention, pupil dilation, tachycardia, irregular urination, and dry skin and mucous membranes.

It is also a potent anticholinergic agent, leading to the side-effects of dry mouth and throat, increased heart rate, pupil dilation, urinary retention, constipation, and, at high doses, hallucinations or delirium.

2C-E can also produce distortions in the user's perception of the passage of time leading to an illusion of moderate to extreme time dilation

Other optimization problems on spanning trees have also been studied, including the maximum spanning tree, the minimum tree that spans at least k vertices, the minimum spanning tree with at most k edges per vertex ( Degree-Constrained Spanning Tree ), the spanning tree with the largest number of leaves ( closely related to the smallest connected dominating set ), the spanning tree with the fewest leaves ( closely related to the Hamiltonian path problem ), the minimum diameter spanning tree, and the minimum dilation spanning tree.

Planned Parenthood has also opposed initiatives that require waiting periods before abortions, and bans on late-term abortions including intact dilation and extraction, which has been illegal in the U. S. since 2003.

In geometry, the Minkowski sum ( also known as dilation ) of two sets of position vectors A and B in Euclidean space is formed by adding each vector in A to each vector in B, i. e. the set

Mixed Dirichlet / Neumann boundary conditions were first considered by Warren Siegel in 1976 as a means of lowering the critical dimension of open string theory from 26 or 10 to 4 ( Siegel also cites unpublished work by Halpern, and a 1974 paper by Chodos and Thorn, but a reading of the latter paper shows that it is actually concerned with linear dilation backgrounds, not Dirichlet boundary conditions ).
