(n.) The act of placing in a circle, or round about, or the state of being so placed.
Example Sentences:
Superposition
Definition:
(n.) The act of superposing, or the state of being superposed; as, the superposition of rocks; the superposition of one plane figure on another, in geometry.
Example Sentences:

(3) We are able to describe our data in terms of a superposition of single and multiple-hit fractions and to show that the latter are greatly increased, in excision-repair-competent strains, by prevention of protein synthesis for 1 h prior to irradiation.
(4) In application to the dorsoventral patterning of insects, it is shown that a superposition of two pattern-forming reactions is required.
(5) The association of mitral leaflets (composed of excess tissue and opposed to flow by a perpendicular position attributable to a narrow mitroaortic angle) and geometric left ventricular modifications (responsible for the superposition of mitral inflow to ventricular outflow) also qualifies as a mechanism for the induction of LVOTO after mitral surgical repair.
(6) The two lobes of the molecule, representing the N-terminal and C-terminal halves, have very similar folding, with a root-mean-square deviation, after superposition, of 1.32 A for 285 out of 330 C alpha atoms; the only major differences being in surface loops.
(7) When the mean pressure values of the potentiated beats in a given experiment are multiplied by a single factor, superposition of the two relationships is obtained.

(9) Such a superposition in general, resulted in a polar-plot with four peaks 90 degrees apart from each other (four-symmetrical polar-plot).
(10) Traditional "stimulus-time-locked signal averaging" of human EEG, as usually practiced in both clinical and basic contexts, assumes the superposition principle of algebraic summation for a linear time series.
(11) If an unselected sample includes individuals whose blood pressure is sensitive to their salt intake and individuals whose blood pressure is not sensitive, then the superposition of these two sub-populations in a scatterplot of individuals' blood pressures against their salt intakes could give a triangular distribution.
(12) Here we examine a simple one-dimensional caricature of their model which exhibits similar linear behaviour and present a nonlinear analysis which shows the possibility of superposition of modes subject to appropriate parameter values and initial conditions.
(13) There is useful information in the deviations from the rigid body superposition.
(14) Taking into account the hypothesis of the superposition of the alloreactive and the anti-self plus conventional antigens T sets of cells, we investigated whether immunization with conventional antigens was able to alter alloreactive T levels.
(15) The relation between the quality of the optical image and the fineness of the retinal mosaic has been studied in eyes of three different optical types: the simple eyes of spiders, the superposition compound eyes of moths, and the apposition compound eyes of butterflies.
(16) A small, but clearly detectable delay of the 'on-field' orientation can be described accurately by the superposition of two exponential processes with opposite amplitudes.
(17) It is shown that the ESR spectra of triple-stranded complex formed by the polyribouridylic acid with the trideoxyadenylate spin-labelled on terminal phosphate is a superposition of the signals with strongly different width of HFS-components.
