Setting physical barriers, for example platform screen doors (PSDs), has been proven to be effective in preventing falls onto railway tracks, but its cost-effectiveness is not known. For economic evaluation of public health interventions, the importance of including non-health factors has been noted despite a lack of empirical studies. This study aimed to investigate the effectiveness and cost-effectiveness of PSDs, which are installed in part of the Hong Kong railway system, for preventing railway injuries.

    We compare the results of a standard GGA exchange-correlation functional with those produced by the newly developed van der Waals exchange-correlation functional. The most striking difference between the two sets of results occurs for the adsorption energies: standard functional predicts values repr...

    We have developed a time-correlated single-photon counting apparatus with which we were not only able to detect the fluorescence of fullerene and its derivatives in water, but could also measure fluorescence temporal decays and determine lifetimes in the range of tens of picoseconds. The compounds s...
