1. Injuries, illnesses, or other conditions for which a health insurance policy does not provide coverage. Exclusions exist because they are thought to be too risky for the health insurance provider. For example, many insurance providers exclude treatment for some types of cancer because they are so expensive to treat. See also: Pre-existing condition.

2. Income that is not considered gross income for tax purposes. Exclusions include gifts, inheritance, and some others. It is important to note that just because a type of income is an exclusion, it does not mean that it is not taxed; it simply may be taxed differently. Exclusions are stated in the U.S. Tax Code.


Medical services that insurance companies do not pay for are called exclusions. A typical exclusion is a wartime injury or a self-inflicted wound.

But coverage for certain pre-existing conditions, or health problems you had before you were covered by the policy, may also be excluded on some policies.


An amount of income that is not included in gross income because the Tax Code excludes it. Examples, include gain from a qualified sale of a principal residence, income earned abroad, and gifts and inheritances.

It is well known that some scholars have doubted the validity of exclusion principle.
For example, in reference [4], it presents that for high-energy celestial bodies such as neutron stars and the like, the broken Pauli exclusion principle will be observed; and points out that the exclusion principle may be broken in high-energy state.

Relying on this nuclear physics example, one deduces that the Pauli exclusion principle is completely consistent with three identical fermions in a [J.sup.[pi]] = [3/2.sup.+] and I = 3/2 ground state.
The discussion presented above shows that there is no need for introducing a new degree of freedom (like color) in order to settle the states of [[DELTA].sup.++], [[DELTA].sup.-] and [[OMEGA].sup.-] baryons with the Pauli exclusion principle. Hence, there is no reason for the QCD invention.
In the following sub-sections, three areas are discussed: The Pauli exclusion principle, chemical reactivity and chemical bonds.
The Pauli Exclusion Principle is an extremely important principle in science [10].
Although physicists commonly invoke the exclusion principle, "you have to measure [its effects] before people really believe it," says Stefan Oberholzer of the University of Basel in Switzerland, where he and his colleagues conducted one of the confirming tests.
The Pauli exclusion principle stands at the heart of modern molecular, atomic and nuclear physics.
The Pauli exclusion principle stands at the basis of the structure and stability of matter.
Mohapatra of the University of Maryland at College Park have developed a theory that permits a slight violation of the exclusion principle. Experiments to test their theory are likely to follow.
In the way they build the superstructures of atoms and in the way they prevent atoms from collapsing, electrons obey a rule called the Pauli exclusion principle. The exclusion principle forces them to follow the Fermi-Dirac statistical law, under which their wave functions can be positive part of the time and negative part of the time.
