| conjoined symmetrical twins | Conjoined twin's in which both members are approximately of the same size, and nearly normal except for the areas of fusion. Synonym: conjoined symmetrical twins. (05 Mar 2000) |
| symmetrical | 1. Involving or exhibiting symmetry; proportional in parts; having its parts in due proportion as to dimensions; as, a symmetrical body or building. 2. <biology> Having the organs or parts of one side correspponding with those of the other; having the parts in two or more series of organs the same in number; exhibiting a symmetry.See Symmetry. 3. <botany> Having an equal number of parts in the successive circles of floral organs; said of flowers. Having a likeness in the form and size of floral organs of the same kind; regular. 4. <mathematics> Having a common measure; commensurable. Having corresponding parts or relations. A curve or a plane figure is symmetrical with respect to a given line, and a line, surface, or solid with respect to a plane, when for each point on one side of the line or plane there is a corresponding point on the other side, so situated that the line joining the two corresponding points is perpendicular to the line or plane and is bisectad by it. Two solids are symmetrical when they are so situate dwith the respect to an intervening plane that the several points of their surfaces thus correspond to each other in position and distance. In analysis, an expression is symmetrical with respect to several letters when any two of them may change places without affecting the expression; as, the expression a^2b + ab^2 + a^2c + ac^2 + b^2c + bc^2, is symmetrical with respect to the letters a, b, c. Symmet"rically, Symmet"ricalness. Origin: Cf. F. Symetrique. See Symmetry. Source: Websters Dictionary (01 Mar 1998) |
| symmetrical gangrene | Gangrene affecting the extremities of both sides of the body; it is seen particularly in severe arteriosclerosis, myocardial infarction, and ball-valve thrombus. (05 Mar 2000) |
| extinction symmetrical | <microscopy> Vibration directions bisecting a prominent crystal profile angle. (05 Aug 1998) |
| lipomatosis, multiple symmetrical | Multiple circumscribed or encapsulated lipomas which may be distributed symmetrically or haphazardly or which may form a collar around the neck. (12 Dec 1998) |
| age distribution | The frequency of different ages or age groups in a given population. The distribution may refer to either how many or what proportion of the group. The population is usually patients with a specific disease but the concept is not restricted to humans and is not restricted to medicine. (12 Dec 1998) |
| Bernoulli distribution | <statistics> The probability distribution associated with two mutually exclusive and exhaustive outcomes, e.g., death or survival. (14 Aug 2000) |
| binomial distribution | The probability distribution associated with two mutually exclusive outcomes; used to model cumulative incidence rates and prevalence rates. The bernoulli distribution is a special case of binomial distribution. (12 Dec 1998) |
| gaussian distribution | Continuous frequency distribution of infinite range. Its properties are as follows: 1) continuous, symmetrical distribution with both tails extending to infinity; 2) arithmetic mean, mode, and median identical; and 3) shape completely determined by the mean and standard deviation. (12 Dec 1998) |
| chi-square distribution | A distribution in which a variable is distributed like the sum of the the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another. (12 Dec 1998) |
| multinomial distribution | Probability distribution associated with the classification of each of a sample of individuals into one of several mutually exclusive and exhaustive categories. (05 Mar 2000) |
| contagious distribution | <epidemiology> Same as an aggregated distribution. (05 Dec 1998) |
| poisson distribution | <epidemiology> The distribution which arises when parasites are distributed at random amongst hosts. (05 Dec 1998) |
| countercurrent distribution | A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (12 Dec 1998) |
