(15) Monkeys aligned a cursor bar with high-contrast square-wave gratings presented in a variety of orientations.
(16) This study examined a visual analog of the PAT in which subjects matched the vertical position of a continually moving horizontal line (target) presented on one side of their point of fixation, with a second line (cursor) presented on the other side of their fixation point.

Recursive
Definition:
Example Sentences:
(1) The feasibility of estimating these parameters, demonstrated by the present study, suggests that a recursive least squares estimation procedure could be used to recover the time variation of each parameter during exercise stress testing of subjects with normal or nearly normal gas exchange.
(2) We have investigated the properties of a recursive process in which the output signal from a given RF excitation pulse may be used as the input (excitation) pulse of a subsequent iteration.
(3) A simple recursive formula, which yields an estimate for the statistical error resulting from pipetting errors accumulated throughout a dilution procedure, is described.
(4) A new three dimensional (3-D) recursive tracing algorithm was proposed.
(5) In the experimental analog, genetic selection or screening applied during recursive ensemble mutagenesis should force the evolution of an ensemble of mutants to a targeted cluster of related phenotypes.

(7) The equilibrium equation for mixtures of two mutually competitive tight-binding ligands can be expressed in a recursive form, a form in which the dependent variable appears on both sides and the solution is found iteratively.
(8) Given the probability density, f(t), for time spent in the random compartment of the cell cycle, we derive a recursion relation for psi n(x), the probability density for cell size at birth in a sample of cells in generation n. For the case of exponential growth of cells, the recursion relation has no steady-state solution.
