since individuals spend the majority of their times indoors, fine particles generated in indoor combustion processes and by resuspension are important for health effects assessment. the nature and magnitude of indoor particle exposures can change rapidly because of the rapid changes in activities and sources. indoor pm 2.5 concentrations were measured in indoor office, café, and home where peop...

Last Time: Simulation Sound NIZKS & Connection to CCA Security. Last time we introduced Simulation-Sound NIZKs, and constructed a 1-Time Simulation Sound NIZK (1-SS NIZK). We then showed how to get CCA secure encryption from CPA encryption and NIZKs in one of two ways: using standard NIZK and n copies of a CPA encryption scheme ([DDN00]) or using 1-SS NIZK and 2 copies of a CPA encryption schem...

Secondhand smoke (SHS) exposure causes death and disease in both nonsmoking adults and children, including cancer, cardiovascular and respiratory diseases. SHS exposure causes an estimated 46,000 heart disease deaths and 3,400 lung cancer deaths among U.S. nonsmoking adults annually. Adopting policies that completely eliminate smoking in all indoor areas is the only effective way to eliminate i...

The chronic effects of smoking on regional cerebral blood flow (CBF), and on serum lipids and lipoprotein levels in neurologically normal subjects, were studied. CBF was studied by the 133-Xenon inhalation method and gray matter flow was calculated following the method of Obrist et al. One hundred and eleven subjects, who had no abnormalities in neurological examinations nor in CT scans, were d...

We propose in this paper a new voting scheme where the voter, while receiving a receipt for his/her vote allowing further contestations, cannot use it to reveal the vote to other unspecified entities, and therefore cannot be forced to do so. The scheme is based on the concept of strong designated verifier signature scheme, and is very cheap in both computation and data communication, regarding ...
