Recent interest in sedentary behavior and technological advances expanded use of watch-size accelerometers for continuous monitoring of physical activity (PA) over extended periods (e.g., 24 h/day for 1 week) in studies conducted in natural living environment. This approach necessitates the development of new methods separating bedtime rest and activity(More)
BACKGROUND To determine the long-term efficacy and persistence of Chinese infants after receiving only active plasma-derived hepatitis B vaccine, and to evaluate if providing booster vaccination after basic hepatitis B immunization is necessary. METHODS Infants who were born in 1986-1988 in four demonstrative hepatitis B immunization trial areas of Hunan,(More)
Efficient emergency rehearse system provides both commanders and evacuation crowds with better preparation for dangerous gas diffusion accidents, which definitely causes serious social panic and huge property loss. This paper focuses on four key issues raised by such accidents in the chemical industry parks. These issues include modeling, simulation,(More)
In this report, we explored the benefits and costs associated with converting the I-394 High Occupancy Vehicle (HOV) lanes to High Occupancy Toll (HOT) lanes. The study focused on the I-394 corridor, with a 10-year timeframe from 2006 to 2015. The benefits included travel time savings, safety benefits, and vehicle operating cost savings, and the costs(More)
