in this study, the possible involvement of l-type voltage-operated calcium channels in the vasorelaxant effect of the flavonoid quercetin was investigated, using the isolated aortic rings from normal male rats. addition of quercetin (0.1 µm-1 mm) caused a significant dose-dependent relaxation of noradrenaline (na)- and kcl-preconstricted rings and nifedipine attenuated this response, especially...
A sensor network localization problem can be formulated as a quadratic optimization problem (QOP). For quadratic optimization problems, semidefinite programming (SDP) relaxation by Lasserre with relaxation order 1 for general polynomial optimization problems (POPs) is known to be equivalent to the sparse SDP relaxation by Waki et al. with relaxation order 1, except the size and sparsity of the ...
