Accurate three-dimensional reactive and nonreactive quantum mechanical cross sections for the H+H2 exchange reaction on the Porter-Karplus potential energy surface are presented. Tests of convergence in the calculations indicate an accuracy of better than 5% for most of the results in the energy range considered (0.3 to 0.7 eV total energy). The reactive differential cross sections are exclusiv...

OBJECTIVE To verify whether the accuracy of data on myocardial function provided by pulsed-wave tissue Doppler imaging (PWTDI), a new echocardiographic application that allows quantitative measurements of myocardial wall velocities, could help towards a better understanding of the natural history of acromegalic cardiomyopathy. DESIGN Eighteen patients with active acromegaly (ten men and eight...
