Purpose of review: The shift of modern dietary regimens from 'Mediterranean' to 'western' style is believed to be responsible, in part, for the increase in cardiovascular disease, obesity, type II diabetes and cancer. A classic 'Mediterranean' diet consists of adequate intake of seafood, vegetables, fruit, whole grain and nonpurified monounsaturated vegetable oil. Thus, in humans, dietary intake of seafood is the major source of taurine, as the level of endogenously produced taurine is low. Recent findings: Taurine has been shown to affect coronary artery disease, blood pressure, plasma cholesterol and myocardial function in animal models of human disease. A major role of taurine is to act as an antioxidant and absorb hypochlorous acid but not the oxidative radical. It seems that this beneficial effect of taurine in antioxidant therapy has not been well promoted. Summary: This review will focus on determining whether taurine could be a factor contributing to the further prevention of heart disease. © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins.

A Hilbert-Pair consists of a pair of filter banks whose corresponding wavelets are Hilbert transforms of each other. Selesnick proposed the simple common-factor technique for its design. The filter transfer functions consist of the product of a factor that is common to both filter banks and a phase factor which gives the (approximate) half-sample-delay requirement. Previously the design of the phase factor has been based on designing an allpass filter approximating the half-sample-delay. This paper proposes a different approach to designing the phase factor by exploiting a basic multirate identity. The downsampling approach allows greater flexibility and can yield filters and wavelets with better properties. © 2010 IEEE. Source

Consensus decision making is complex and challenging in multicriteria group decision making due to the involvement of several decision makers, the presence of multiple, and often conflicting criteria, and the existence of subjectiveness and imprecision in the decision making process. To ensure effective decisions being made, the interest of all the decision makers usually represented by the degree of consensus in the decision making process has to be adequately considered. This paper presents a consensus-based approach for effectively solving the multicriteria group decision making problem. The subjectiveness and imprecision of the decision making process is adequately handled by using intuitionistic fuzzy numbers. An interactive algorithm is developed for consensus building in the group decision making process. A decision support system framework is presented for improving the effectiveness of the consensus building process. An example is presented for demonstrating the applicability of the proposed approach for solving the multicriteria group decision making problem in real world situations. © 2013 Elsevier Ltd.

A symmetric self-Hilbertian filter is a product filter that can be used to construct orthonormal Hilbert-pair of wavelets for the dual-tree complex wavelet transform. Previously reported techniques for its design does not allow control of the filters frequency response sharpness. The Zero-Pinning (ZP) technique is a simple and versatile way to design orthonormal wavelet filters. ZP allows the shaping of the frequency response of the wavelet filter by strategically pinning some of the zeros of the parametric Bernstein polynomial. The non-zero Bernstein parameters, αis, are the free-parameters and are constrained in number to be twice the number of pinned zeros in ZP. An extension to ZP is presented here where the number of free-parameters is greater than twice the number of pinned zeros. This paper will show how the extended ZP can be used to the design of Hilbert pairs with the ability to shape the filter response. © 2011 Elsevier B.V. All Rights Reserved. Source

Where hemispheric lateralization was once considered an exclusively human trait, it is increasingly recognized that hemispheric asymmetries are evident throughout the animal kingdom. Emotion is a prime example of a lateralized function: given its vital role in promoting adaptive behavior and hence survival, a growing body of research in affective neuroscience is working to illuminate the cortical bases of emotion processing. Presuming that human and non-human primates evolved from a shared ancestor, one would anticipate evidence of organizational continuity in the neural substrate supporting emotion processing. This paper thus reviews research examining the patterns of lateralization for the expression and perception of facial emotion in non-human primates, aiming to determine whether the patterns of hemispheric asymmetry that characterize the human brain are similarly evident in other primate species. As such, this review seeks to enhance understanding of the evolution of hemispheric specialization for emotion, using emotion lateralization in non-human primates as a window through which to view emotion lateralization in humans. © 2013 Lindell.
