If the former occurs, then any subsequent measurement performed by Bob, in the same basis, will always return 1.

If the latter occurs, ( Alice measures 1 ) then Bob's measurement will return 0 with certainty.

If an interrupt occurs that makes a high priority task ready during the insertion of a low priority task, that high priority task can be inserted and run immediately before the low priority task is inserted.

If the full moon occurs on a Sunday, Easter is the following Sunday.

If the full moon occurs on a Sunday, Easter is the following Sunday.

If one throws a die once, it is difficult to predict the outcome, but if we repeat this experiment many times, we will see that the number of times each result occurs divided by the number of throws will eventually stabilize towards a specific value.

If this practice should take root and spread, the man who submits a manuscript to a publisher will find himself reviewed before he is accepted and publication will become a sort of post-mortem formality.

If they don't then for the algorithm to be effective it must provide a set of rules for extracting a square root.

If F is algebraically closed and p ( x ) is an irreducible polynomial of F, then it has some root a and therefore p ( x ) is a multiple of x − a.

* If the balance factor of R is-1, a single left rotation ( with P as the root ) is needed ( Right-Right case ).

* If the balance factor of L is + 1, a single right rotation ( with P as the root ) is needed ( Left-Left case ).

If the rotation leaves the subtree's balance factor at 0 then the retracing towards the root must continue since the height of this subtree has decreased by one.

A number a is a root of P if and only if the polynomial x − a ( of degree one in x ) divides P. It may happen that x − a divides P more than once: if ( x − a )< sup > 2 </ sup > divides P then a is called a multiple root of P, and otherwise a is called a simple root of P. If P is a nonzero polynomial, there is a highest power m such that ( x − a )< sup > m </ sup > divides P, which is called the multiplicity of the root a in P. When P is the zero polynomial, the corresponding polynomial equation is trivial, and this case is usually excluded when considering roots: with the above definitions every number would be a root of the zero polynomial, with undefined ( or infinite ) multiplicity.

If, however, the set of allowed candidates is expanded to the complex numbers, every non-constant polynomial has at least one root ; this is the fundamental theorem of algebra.

If the quantity under the square root ( the discriminant ) is negative, then the ray does not intersect the sphere.

If a root candidate does not satisfy the equation, it can be used to shorten the list of remaining candidates.

If a root r < sub > 1 </ sub >

If the material superconducts in the absence of a field, then the superconducting phase free energy is lower than that of the normal phase and so for some finite value of the magnetic field ( proportional to the square root of the difference of the free energies at zero magnetic field ) the two free energies will be equal and a phase transition to the normal phase will occur.

If gg is null, then x obviously is now the root and must be updated as such.

If one compares explosions with different yields, the EMP at a fixed distance from a nuclear weapon would not increase at the same rate as the explosion yield, but at most only as the square root of the yield ( see the illustration to the right ).

If threads are cut into a cylindrical rod, that minimum area occurs at the root of the thread.

* Root pressure: If the water potential of the root cells is more negative than that of the soil, usually due to high concentrations of solute, water can move by osmosis into the root from the soil.

If it is top-killed and burned away in a larger fire, it easily resprouts and has a good supply of nutrients and water stored in its root system.

If hair is pinned too tightly, or the whole updo slips causing pulling on the hair in the follicle at the hair root are other scenarios that can cause aggravation to the hair follicle and result in headaches.

If the name has an Indo-European etymology, it is possibly a suffixed form of a root * wel-" to turn, roll ", or of * sel-" to flow, run ".< ref > The American Heritage Dictionary, " Indo-European roots: wel < sup > ₂ </ sup >"</ ref > The latter possibility would allow comparison to the Vedic Sanskrit Saraṇyū, a character who is abducted in Rigveda 10. 17. 2.
