Towards fully ab initio simulation of atmospheric aerosol nucleation.

Atmospheric aerosol nucleation contributes to approximately half of the worldwide cloud condensation nuclei. Despite the importance of climate, detailed nucleation mechanisms are still poorly understood. Understanding aerosol nucleation dynamics is hindered by the nonreactivity of force fields (FFs) and high computational costs due to the rare event nature of aerosol nucleation.

[A histopathological study on Influenza A H1N1 infection in humans].

Objective: To find histopathological changes on major organs of Influenza A H1N1-infected patients and its relationship to clinical symptoms.

Methods: The autopsies were performed following conventional protocols and strict safety procedures. Tissue samples from all major organs of three cases were collected and fixed in 4% formalin.
