In migration and DMO, the kinematic problem is easier to solve than the amplitude problem. Where a purely analytical approach is normally used to obtain the amplitude of a migration operator, we attempt to obtain amplitude information by combining an assumption of a at spectrum with the kinematical formulation. This hyperbola whitening is done with a 2-D prediction-error lter. This technique is...

This paper aims at obtaining performance limitations of state estimation in terms of variance minimization (minimum variance estimation and filtering) using information theory. Two new notions, negentropy rate and Gaussianity-whiteness measure (joint Shannon-Wiener entropy), are proposed to facilitate the analysis. Topics such as Gaussianing-whitening filter (the maximum Gaussianity-whiteness m...

This study presents a comprehensive assessment of the variability and trends of the precipitation and temperature along with the trends in drought indices over the State of California. The non-parametric Mann–Kendall trend test is applied with a trend-free pre-whitening procedure in trend identification. A dataset containing 120-year (water years 1896–2015) monthly precipitation, average temper...

Background and aim: the present study aimed to assess the effect of teeth whitening strips on dental plaque pH in vivo. Materials and Methods: This in vivo experimental study was conducted on 21 individuals, who were requested to use Crest 3D whitening strips for 30 minutes once a day and for 14 days according to the manufacturer’s instructions. Dental plaque pH was measured using GC p...

Bleaching tetracycline-stained teeth is the most challenging form of tooth lightening. This article reports on 44 subjects who bleached their tetracycline-stained teeth for 6 months using trays with reservoirs overnight in a half-mouth designed study and 2 of 3 different concentrations of carbamide peroxide (10%, 15% or 20%). The subjects were followed for 5 years. The area evaluated was the mi...
