Radio channel reservation is used to alleviate call dropping which may occur in two situations: (i) hand-off between cells in cellular networks, and (ii) channel withdrawal in wireless networks with spectrum leasing. In this article, we study a radio resource reservation scheme for heterogeneous traffic in a cellular network with spectrum leasing, in which(More)
The objective of this study was to assess whether preoperative breast magnetic resonance imaging (MRI) combined with conventional breast imaging techniques decreases the rates of margin involvement and reexcision.Data on patients who underwent surgery for primary operable breast cancer were obtained from the Changhua Christian Hospital (CCH) breast cancer(More)
Cognitive capillary machine type communication networks provide machine-to-machine communication for devices due to the advantage of the reduction in the power consumption of machines, the simplification of designing machines, the low design cost of machines and the reduction in the frequency of accessing base stations. In such an architecture, a multiple(More)
In this study, we assessed the diagnostic accuracy of breast magnetic resonance imaging (MRI) for evaluation of malignant invasion of the nipple-areolar complex (NAC).Patients with primary operable breast cancer who underwent preoperative breast MRI and received surgery during January 2011 to December 2013 were collected. The accuracy and potential factors(More)
Vehicular networks provide Internet services for car drivers. Multiple radio access technologies are usually used in existent mobile devices and are expected in the next generation wireless networks. A vehicle equips with one cognitive radio interface or WiFi interface can communicate with neighbor vehicles or base stations. It is critical for electrical(More)
