QCD suggests that gluons in the nucleon play an important role in so-called " the proton spin problem ". In this talk, the behavior of the polarized gluon distribution in the nucleon is discussed by using the positivity condition of distribution functions together with the unpolarized and polarized experimental data.

In this thesis, a system for automatic facial expression analysis was designed and implemented. This system includes a monocular 3d head pose tracker to handle rigid movements, feature extraction based on Gabor wavelets and gradient orientation histograms, and a SVM classifier. Further more, a database with video sequences of acted and natural facial expression was compiled and tests were done,...

Abstract Background High-density lipoprotein (HDL) cholesterol levels are inversely associated with cardiovascular risk (CVR). However, HDL is not a homogeneous lipid and can be subdivided into subfractions, which uniformly CVR. Among Roma populations, the prevalence of reduced and, consequently, that diseases very high. it known how this reduction affects different subfractions whether changes...

RATIONALE CSL112, human apolipoprotein A-I (apoA-I) reconstituted with phosphatidylcholine, is known to cause a dramatic rise in small high-density lipoprotein (HDL). OBJECTIVE To explore the mechanisms by which the formation of small HDL particles is induced by CSL112. METHODS AND RESULTS Infusion of CSL112 into humans caused elevation of 2 small diameter HDL fractions and 1 large diameter...
