Recent technological trends facilitate threedimensional stereophony. To this day, no internationally agreed standard for three-dimensional sound reproduction exists. Fundamental research is needed to define basic system parameters and ensure compatibility between different formats. Background in spatial audio perception, stereophonic audio reproduction, and automatic channel format conversion i...

Choline is a vitamin-like substance it has multi-function in animal production, reproduction, and health. The transition period is most crucial stage in lactation cycle of dairy cows due to its association with negative hormonal and energy balances. Unfortunately, unprotected choline easily degrades in the rumen; therefore, choline added to the diet in a rumen-protected form. The use of rumen-p...

Compartmental models for influenza that include control by vaccination and antiviral treatment are formulated. Analytic expressions for the basic reproduction number, control reproduction number and the final size of the epidemic are derived for this general class of disease transmission models. Sensitivity and uncertainty analyses of the dependence of the control reproduction number on the par...
