Abstract Increased competition can result in market efficiency. However, alternatively, it may provoke unethical behavior by sellers attempting to avoid losses—a risk that be greater credence goods markets, where consumers find difficult determine the value of or services received. The New York City (NYC) taxi allows us investigate how increased due launch green-colored taxis (to serve only cer...

Network reconfiguration and emergency power vehicles (EPVs) dispatching are widely used in distribution networks for load restoration. However, their capabilities limited by the allocated amounts of circuit breakers EPVs. E-taxis can also participate restoration as a kind mobile energy storage using vehicle to grid (V2G) technology. uncertainty should be considered To achieve better effectivene...

Mitigating traffic congestion on urban roads, with paramount importance in urban development and reduction of energy consumption and air pollution, depends on our ability to foresee road usage and traffic conditions pertaining to the collective behavior of drivers, raising a significant question: to what degree is road traffic predictable in urban areas? Here we rely on the precise records of d...

beta-Methylgalactoside (mgl) permease mutants of Escherichia coli, which are defective in three genes, mglA, mglB, and mglC, were assayed for galactose taxis and galactose transport. The mglB product is the galactose-binding protein. Previous evidence, supported by our new findings, shows that the galactose-binding protein is the recognition component for galactose taxis as well as for galactos...

A dilute suspension of motile microorganisms subjected to a strong ambient flow, such as algae in the ocean, can be modelled population non-interacting, orientable active Brownian particles (ABPs). Using Smoluchowski equation (i.e. Fokker–Planck space and orientation), one describe non-trivial transport phenomena ABPs taxis shear-induced migration. This work transforms into equation, which drif...

The increasing availability of large-scale trajectory data provides us great opportunity to explore them for knowledge discovery in transportation systems using advanced data mining techniques. Nowadays, large number of taxicabs in major metropolitan cities are equipped with a GPS device. Since taxis are on the road nearly twenty four hours a day (with drivers changing shifts), they can now act...

Contrary to microbial taxis, where a tactic response to external stimuli is controlled by complex chemical pathways acting like sensor-actuator loops, taxis of artificial microswimmers is a purely stochastic effect associated with a non-uniform activation of the particles’ self-propulsion. We study the tactic response of such swimmers in a spatio-temporally modulated activating medium by means ...

Chemotaxis enhances the fitness of Salmonella enterica serotype Typhimurium (S. Typhimurium) during colitis. However, the chemotaxis receptors conferring this fitness advantage and their cognate signals generated during inflammation remain unknown. Here we identify respiratory electron acceptors that are generated in the intestinal lumen as by-products of the host inflammatory response as in vi...

Although the demand for taxis is increasing rapidly with the soaring population in big cities, the number of taxis grows relatively slowly during these years. In this context, private transportation such as Uber is emerging as a flexible business model, supplementary to the regular form of taxis. At present, much work mainly focuses on the reduction or minimization of taxi cruising miles. Howev...
