This work presents the development of a system that detects incorrect uses of complex postpositions in Basque, an agglutinative language. Error detection in complex postpositions is interesting because: 1) the context of detection is limited to a few words; 2) it implies the interaction of multiple levels of linguistic processing (morphology, syntax and semantics). So, the system must deal with...

The cross section for Drell-Yan pair production in the limit of small x target is derived in the rest frame of the target hadron. Our calculation is based on the fundamental quantity σ(ρ), the cross section for the scattering of a q ¯ q-pair with fixed transverse separation ρ off a hadronic target. As in deep inelastic scattering the result can be given in terms of integrals of σ(ρ). This is co...

Most of our research has been focused on the higher brain functions of the mammalian central nervous system, in particular, the neural mechanisms of cognitive memory in the primate. The basic motivation of the research can be best explained as follows: Knowledge or experiences are voluntarily recalled from memory by reactivation of their neural representations in the cerebral association cortex...

In vitro studies on interactions between amelogenins and calcium phosphate crystals are critical for elucidating biomineralization mechanisms of tooth enamel. This work was aimed at investigating the effects of native porcine amelogenins on octacalcium phosphate (OCP) crystal growth in a gelatin gel. We prepared OCP mineral discs by circulating calcium and phosphate solutions on the opposite en...
