A traditional traffic signal control system is established based on vehicular delay, queue length, saturation and other indicators. However, due to the increasing severity of urban environmental pollution issues and the development of a resource-saving and environmentally friendly social philosophy, the development of low-carbon and energy-efficient urban transport is required. This paper first...

Vehicle exhaust emissions have posed a serious threat in recent years to the urban air quality of Beijing. It is necessary to accurately estimate the magnitude and distribution of these emissions in order to reduce the uncertainty of local scale air quality modeling assessment. This paper provides a bottom-up approach by combining vehicle emission factors and vehicle activity data from a travel...

excessive exposure to noise can lead to noise-induced hearing loss. otoacoustic emissions affect the microscopic biomechanical activities of healthy outer hair cells. the present study aimed at assessing the influence of various sound pressure levels on distortion product otoacoustic emissions (dpoaes) in rats. to this end, 27 adult male rats with an age range of 3 to 4 months and a weight of 2...

background: the possible role of cochlear function in tinnitus generation is still a matter of debate. to assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (uhf) hearing sensitivity, transient evoked otoacoustic emissions (teoae) and uhf hearing thresholds were investigated in normal hearing individuals with and without tinnitus. ...

The biogenesis of peptide hormone secretory granules involves a series of sorting, modification, and trafficking steps that initiate in the trans-Golgi and trans-Golgi network (TGN). To investigate their temporal order and interrelationships, we have developed a pulse-chase protocol that follows the synthesis and packaging of a sulfated hormone, pro-opiomelanocortin (POMC). In AtT-20 cells, sul...
