Our recent study showed that the Bayer-dithering technique could substantially improve 3D measurement quality for the binary defocusing method. Yet, the dithering technique was developed to optimize the appearance or intensity representation, rather than the phase, of an image. This paper presents a framework to optimize the Bayer-dithering technique in phase domain by iteratively mutating the ...

In the present study, prediction of Alumina recovery efficiency (A.R.E), the amount of produced red mud (A.P.R), red mud settling rate (R.S.R) and bound-soda losses (B.S.L) in Bayer process red mud has been carried out for the first time in the field. These predictions are based on Lime to bauxite ratio and chemical analyses of bauxite and lime as Bayer process feed materials. Radial basis func...

Most color imaging systems today are based on a monochrome detector with a color filter array (CFA). Typically the Bayer CFA is used. An imaging system’s spatial frequency response (SFR) is one of its most meaningful characteristics. It is directly related to the system’s capability to resolve objects. This work presents a model for calculating the SFR of a Bayer color capture system. Our two d...

This review considers evidence for a protective effect of PUFA on chronic disease. Estimates of PUFA intakes in prospective cohort studies are usually based on FFQ or biomarkers of intake. Cohort studies suggest that both linoleic and linolenic acid intake are associated with a lower risk of CHD. The intake of fish, the major source of long-chain n-3 PUFA is associated with a lower risk of both...

How proteins with new functions (e.g., drug or antibiotic resistance or degradation of man-made chemicals) evolve in a matter of months or years is still unclear. This ability is dependent on the induction of new phenotypic traits by a small number of mutations (plasticity). But mutations often have deleterious effects on functions that are essential for survival. How are these seemingly confli...

Renal clearance (CLR), a major route of elimination for many drugs and drug metabolites, represents the net result of glomerular filtration, active secretion and reabsorption, and passive reabsorption. The aim of this study was to develop quantitative structurepharmacokinetic relationships (QSPKR) to predict CLR of drugs or drug-like compounds in humans. Human CLR data for 382 compounds were ob...

Two well known derivatization methods, butylation and methylation, are compared by gas chromatography (GC)-mass spectrometry (MS) to identify organic acids in Bayer liquors. These two derivatization methods should be combined together for the determination of the carboxylic acids. Twenty-four organic acids are identified by GC-MS and 13 organic acids are firstly found in Bayer liquors. The rete...

Gorgonian octocorals (order Alcyonacea) are the most abundant components of shallow eastern Pacific marine communities (Breedy & Guzman, 2003a). They occur mainly in zones of strong current swell and breaking surf, attached to rocky bottoms, shells, and small rock fragments (Breedy & Guzman, 2002). Although abundant, the eastern Pacific octocoral fauna was considered poorly known by Bayer (1981...
