Abstract Tangshan West Comprehensive Passenger Terminal is an important passenger terminal of Railway Station. The purpose this paper to make a scientific and reasonable transportation organization design for Station, in order improve the travel service capacity provide good experience passengers. Based on analysis introduction internal structure Transportation Hub designs traffic Station accor...

Autotransporters are a superfamily of bacterial virulence factors consisting of an N-terminal extracellular ('passenger') domain and a C-terminal β barrel ('β') domain that resides in the outer membrane (OM). The mechanism by which the passenger domain is secreted is poorly understood. Here we show that a conserved OM protein insertase (the Bam complex) and a molecular chaperone (SurA) are both...

This paper explores the use of pedestrian conveyor systems, otherwise known as moving walkways, in long public corridors such as those found in major commercial airports. The investigation includes a brief comparison of moving walkways with other primary modes of airport terminal passenger transportation and an empirical study of the use of moving walkways through analysis of passenger conveyor...

Transportation terminal is the key node in transport systems. Efficient terminals can improve operation of passenger transportation networks, adjust the layout of public transportation networks, provide a passenger guidance system, and regulate the development of commercial forms, as well as optimize the assembly and distribution of modern logistic modes, among others. This study aims to clarif...

The immunoglobulin A protease family of secreted proteins are derived from self-translocating polyprotein precursors which contain C-terminal domains promoting the translocation of the N-terminally attached passenger domains across gram-negative bacterial outer membranes. Computer predictions identified the C-terminal domain of the Escherichia coli adhesin involved in diffuse adherence (AIDA-I)...

Bacterial autotransporters are comprised of an N-terminal 'passenger domain' and a C-terminal beta barrel ('beta domain') that facilitates transport of the passenger domain across the outer membrane. Following translocation, the passenger domains of some autotransporters are cleaved by an unknown mechanism. Here we show that the passenger domain of the Escherichia coli O157:H7 autotransporter E...

The passenger’s motion behavior during the check-in process will directly influence efficiency. However, little effort has been made to study this topic. This paper incorporates into route guidance strategy enhance Firstly, an extended social force (SF) model is developed describe each movement at airport terminal. Secondly, a accounting for flight’s remaining departure time and passenger densi...

BACKGROUND The serine protease autotransporter EspP is a proposed virulence factor of Shiga toxin-producing Escherichia coli (STEC). We recently distinguished four EspP subtypes (EspPalpha, EspPbeta, EspPgamma, and EspPdelta), which display large differences in transport and proteolytic activities and differ widely concerning their distribution within the STEC population. The mechanisms underly...
