BACKGROUND AND PURPOSE Telemedicine techniques can be used to address the rural-metropolitan disparity in acute stroke care. The Stroke Team Remote Evaluation Using a Digital Observation Camera (STRokE DOC) trial reported more accurate decision making for telemedicine consultations compared with telephone-only and that the California-based research network facilitated a high rate of thrombolysi...

The deregulation of aviation markets led to restructuring of airline networks. Hub-andspoke networks became the dominant network in countries (regions) where aviation markets were deregulated. These developments were primarily cost driven. Because of increasing returns with density, a hub-and-spoke network allows the large carriers to benefit from substantial cost savings compared to a fully co...

Quantum repeaters are critical to the development of quantum networks, enabling rates entanglement distribution beyond those attainable by direct transmission. We consider multiple continuous-variable, squeezed light-based flows through a repeater involving noiseless linear amplification and dual homodyne detection. By analyzing single-repeater-enhanced channel model with asymmetric half-channe...

this paper proposes a new mathematical model for designing and planning postal parcels carriage and postal networks. the objective of postal network designing is to determine the location, size and connection between the postal stations in a city, province or country. in this paper, a kind of multiple locations-allocations hub problem with limited capacity in collecting, distributing and broadc...
