exclusive or

[ik¦sklü·siv ′ȯr]
(computer science)
An instruction which performs the “exclusive or” operation on a bit-by-bit basis for its two operand words, usually storing the result in one of the operand locations. Abbreviated XOR.
(mathematics)
A logic operator which has the property that if P is a statement and Q is a statement, then P exclusive or Q is true if either but not both statements are true, false if both are true or both are false.

exclusive or

(logic)
(XOR, EOR) /X or, E or/ A two-input Boolean logic function whose result is true if one input is true and the other is false. The truth table is

A | B | A xor B --+---+-------- F | F | F F | T | T T | F | T T | T | F

The output is thus true if the inputs are not equal. If one input is false, the other is passed unchanged whereas if one input is true, the other is inverted.

In Boolean algebra, exclusive or is often written as a plus in a circle: "⊕". The circle may be omitted suggesting addition modulo two.

In digital logic, an exclusive or logic gate is drawn like a normal inclusive or gate but with a curved line across both inputs: exclusive or gate.

Since the cavity temperature ideally never changes, and the electrical nonequivalence and resulting thermal gradients are negligible, the LOCR's response time is determined primarily by the response time of the electronic control system, and is not limited by the heating time constant of the cavity.
Our preliminary interpretation of a possible reason for this nonequivalence concerns the outlying point indicated by the circle in Figure 4.

As O'Driscoll points out in a brief yet delightful 1977 JPE article that as an empirical proposition, it is Ricardian Nonequivalence rather than Equivalence Hypothesis that is supposed to hold.
The first good experimental evidence of such genetic nonequivalence came in 1984, in experiments performed by James McGrath and Davor Solter of the Wistar Institute of Anatomy and Biology in Philadelphia.
The elements within the compound stimuli could maintain an equivalence or nonequivalence relation.
In the equating literature, a recurring concern is that equating functions that utilize a single anchor to account for examinee groups' nonequivalence are biased when the groups are extremely different and/or when the anchor only weakly measures what the tests measure.
