We perform a first-principles semi-classical computation of the one-loop corrections to the dispersion relation and S-matrix of Giant Magnons in AdS5 × S5 string theory. The results agree exactly with expectations based on the strong coupling expansion of the exact Asymptotic Bethe Ansatz equations. In particular we reproduce the Hernandez-Lopez term in the(More)
BACKGROUND Circulating endothelial cells (CEC) may be a biomarker of vascular injury and pro-thrombotic tendency, while circulating endothelial progenitor cells (CEP) may be an indicator for angiogenesis and vascular remodelling. However, there is not a universally accepted standardized protocol to identify and quantify these cells and its clinical(More)
In this dissertation, we discuss how our understanding of the large-N spectrum of AdS/CFT has been deepened by integrability-based approaches. We begin with a comprehensive review of the integrability of the gauge theory spin-chain and that of the string sigma model. In the light of the AdS/CFT duality, they should be just two ways of describing the same(More)
BACKGROUND The increase in life expectancy of elderly population has aroused the interest of different knowledge areas in understanding the variables that are involved in the aging process, linking them to other concepts such as active aging, healthy aging and the bio-psycho-social changes. OBJECTIVE This paper presents the results of the first(More)
Swimming evaluation it’s the most appropriate procedure to analyze the development of a swimmer since age group swimming. The training control provides tools to prescribe intensities and volumes of training, but also assesses the improvement of each swimmer throughout that prescription. In the season 2007/2008 Leiria’ Swimming Association had 419 swimmers(More)
: To evaluate the plasma levels of soluble endothelial cell molecules in patients with venous thromboembolism (VTE) out of the acute phase as compared with healthy individuals. We also investigated the possible associations of the soluble endothelial cell molecules among them, as well as with other clinical and laboratory data, including the numbers of(More)
Nowadays, one major concern is to ensure that enterprises have implemented relevant anti-bribery controls in organizations, view as an information system, without putting at risk its operation. Anti-bribery risk management has become an essential activity, allowing people to assess bribery risks and identify procedures to mitigate risks, in an efficient(More)
