In the communication network pricing literature, it is the linear pricing schemes that have been largely adopted as the means of controlling network usage or generating profits for network service providers. This paper extends the framework to nonlinear pricing and investigates optimal nonlinear pricing policy design for a monopolistic service provider. The(More)
Organic/inorganic, hybrid, multifunctional, material-based platforms combine the merits of diverse functionalities of inorganic nanoparticles and the excellent biocompatibility of organic systems. In this work, superparamagnetic poly(lactic-co-glycolic acid) (PLGA) microcapsules (Fe(3)O(4)/PLGA) have been developed, as a proof-of-concept, for the(More)
Ethyl pyruvate (EP) is protective in experimental models of many illnesses. This study investigates whether EP can protect against neonatal hypoxic-ischemic (H-I) brain injury. Pre-treatment with EP significantly reduced brain damage at 7 days post-H-I, with 50 mg/kg EP achieving over 50% recovery in tissue loss compared to vehicle-treated animals. Delayed(More)
Streptococcus suis serotype 2 (SS2) causes septic shock and meningitis. However, its pathogenesis is still not well-understood. We have recently shown that superoxide dismutase sodA of SS2 is a virulence factor probably by increasing resistance to oxidative stresses. Reactive oxygen species (ROS) are products of the respiratory burst of phagocytic cells and(More)
Noncooperative game theory is used as a basis for analyzing, developing, and implementing decision, control, and resource allocation schemes to address various network control problems such as congestion control, code division multiple access (CDMA) power control, and network intrusion detection and response. In the cases of CDMA power control and(More)
A special "small to big" temperature-responsive phase-transformation strategy based on the "acoustic droplet vaporization (ADV)" mechanism is developed for efficient targeted ultrasonography and synergistic high intensity focused ultrasound (HIFU) cancer surgery by engineering targeted nanoemulsions, which is systematically evaluated and successfully(More)
In this paper, we introduce the concept of dynamic pricing within the context of our previous Stackelberg network game model and view the ISP’s policy as an incentive policy, and the underlying game as a reverse Stackelberg game. We study this incentive-design problem under complete information as well as incomplete information. In both cases, we show that(More)
It has been widely recognized that the current under-utilization of spectrum across many bands could be alleviated through the application of spectrum markets. So far, discussions of market mechanisms for spectrum allocations have focused primarily on secondary markets, which are managed by licensees. Here we explore the consequences of lifting current(More)
