We investigate the capability of the NLC to indirectly determine both the mass as well as the couplings to leptons and b-quarks of a new neutral gauge boson below direct production threshold. By using data collected at several different values of the collider center of mass energy, we demonstrate how this can be done in an anonymous and model-independent manner. The procedure can be easily exte...

During the last decade a lot of effort has been devoted to study in detail generalized parton distributions (GPDs) as well as transverse momentum dependent parton distributions (TMDs). While GPDs enter the QCD description of hard exclusive reactions on the nucleon, TMDs appear in connection with various semi-inclusive processes. Recent work has suggested for the first time very interesting non-...

The biomineralization of bovine pericardium (BP) heart valve bioprostheses was investigated by simulation of the process under in vitro and in vivo conditions. The nature and composition of calcific deposits that formed in human heart valve bioprostheses were compared with the mineral formed on BP discs immersed in a calcifying medium or subcutaneously implanted into Sprague-Dawley rats. The ea...
