objective: since colposcopy biopsy test plays a significant role in the evaluation of cervix, especially in patients with an abnormal result of pap smear test, therefore, this research study was conducted to compare the results of pap smear and colposcopy directed punch biopsy tests at firoozgar and akbarabady hospitals from 2001 to 2003. materials and methods: this cross-sectional study was ca...

In using pooling designs to identify clones containing a specific subsequence called positive clones, sometimes there exist nonpositive clones which can cancel the effect of positive clones. Various models have been studied which differ in the power of cancellation. Although the various models pose interesting mathematical problems, and ingenious constructions of pooling designs have been propo...

Randomisation is a method to test the statistical significance of a symbolic rule; it is, however, very expensive. In this paper we present a sequential randomisation test which dramatically reduces the number of steps needed for a conclusion.

Distributive lattices are well known to be precisely those lattices that possess cancellation: x ∨ y = x ∨ z and x ∧ y = x ∧ z imply y = z. Cancellation, in turn, occurs whenever a lattice has neither of the 5-element lattices M3 or N5 as sublattices. In this paper we examine cancellation in skew lattices, where the involved objects are in many ways lattice-like, but the operations ∧ and ∨ no l...
