Flavour changing strong interaction effects on top quark physics at the LHC

We perform a model independent analysis of the flavour changing strong interaction vertices relevant to the LHC. In particular, the contribution of dimension six operators to single top production in various production processes is discussed, together with possible hints for identifying signals and setting bounds on physics beyond the standard model.Comment: Authors corrections (references added

A Flexible Implementation of a Matrix Laurent Series-Based 16-Point Fast Fourier and Hartley Transforms

This paper describes a flexible architecture for implementing a new fast computation of the discrete Fourier and Hartley transforms, which is based on a matrix Laurent series. The device calculates the transforms based on a single bit selection operator. The hardware structure and synthesis are presented, which handled a 16-point fast transform in 65 nsec, with a Xilinx SPARTAN 3E device.Comment: 4 pages, 4 figures.

Avaliação da composição de acessos de mandioca para carotenoides totais e compostos cianogênicos.

A mandioca (Manihot esculenta Crantz) é uma das mais importantes culturas de reserva contra a fome nos trópicos e subtrópicos, sendo alimento para mais de 800 milhões de pessoas em todo o mundo. Além de rica em carboidratos, a mandioca é uma excelente fonte de betacaroteno (precursor da vitamina A) nas raízes de coloração amarela

Associations between neck circumference and adipocytokines among adolescents

Neck circumference (NC) was recently introduced as a predictor of cardiovascular disease (CVD) risk factor. Adipocytokines may have a key role in the development of CVD. Aims: The purpose of this study was to examine the associations between NC and adipocytokines, such as adiponectin and leptin in Portuguese adolescents.info:eu-repo/semantics/publishedVersio
