Remote roadside smog testing equipment will be located for a few days at a time at more than 100 sites across four counties, most likely on freeway on-ramps. Some locations may alter or slow traffic flow as checkpoint personnal will direct only certain polluting vehicles to the roadside smog...
Robustness test This study employs three robustness testing approaches to enhance the reliability of the findings. First, the measurement method of the dependent variable is substituted. Sec- ond, the study utilizes a propensity scores matching (PSM) model. Third, the potential X iaobao et ...
Climate change will increase the frequency and severity of supply chain disruptions and large-scale economic crises, also prompting environmentally protective local policies. Here we use econometric time series analysis, inventory-driven price
The emission and fuel cost are two distinct and conflicting objective functions that can be combined using a price penalty factor to create a simpler single-objective function expressed as follows: [Math Processing Error]minFCEED=F+hE (8) The variable “h” represents a price-penalty factor (...
Unfortunately, one of the larger PiB-PET studies in CAA (Gurol et al., 2013) did not present data on posterior predominance of amyloid tracer retention level in CAA, which would have been useful for further testing this hypothesis. Overall, therefore, the expected difference in anterior/...
