It was summer in the northern hemisphere, and therefore travelling and vacation time, which also provided an increased opportunity for the dissemination of respiratory diseases. METHODOLOGY: We reviewed the paper case report forms from all the patients with influenza-like il...
a realistic potential energy surface previously reported by the authors. It is shown that the trajectories are exponentially diverging even for very low energies close to the bottom of the potential well. This fact is confinned by the calculated maximum Lyapunov characteristic numbers, which suggest that the Na3 molecule possesses a small vibrational relaxation time. This result corroborates previous findings o...
