Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by the death of motor neurons, axon degeneration, and denervation of neuromuscular junctions (NMJ). Here we show that death receptor 6 (DR6) levels are elevated in spinal cords from post-mortem samples of human ALS and from SOD1(G93A) transgenic mice, and DR6 promotes motor(More)
This paper considers the suitability of a range of multi-input–multi-output (MIMO) orthogonal frequency-division multiplexing architectures for use in urban hotspots. A ray-tracing propagation model is used to produce realistic MIMO channel data. This information is used to determine the expected throughput and area coverage for various physical (PHY) layer(More)
The latest mobile WiMAX standard promises to deliver high data rates over extensive areas and to large user densities. More specifically, data rates are expected to exceed those of conventional cellular technologies. The IEEE 802.16e WiMAX standard enables the deployment of metropolitan area networks to mobile terminals in non-line-of-sight radio(More)
This paper uses a detailed site-specific channel model to analyze the impact of path loss and Co-Channel Interference (CCI) in a multi-basestation Broadband Fixed Wireless Access (BFWA) network. The basestations are deployed in an urban setting and make use of sectorised multi-element arrays to suppress CCI from other cells/sectors. Customer Premises(More)
OBJECTIVES To describe the time course and characteristics of an insecticide-associated incident and highlight potential risks from similar outbreaks that may occur in other areas to enhance the preparedness of emergency physicians and other healthcare providers to deal with the sequelae of these events. STUDY DESIGN Outbreak investigation METHODS From(More)
The present study shows that hip fracture women had higher serum periostin (sPostn) levels. The elevation of sPostn is associated with bone density loss, yet fracture itself may even increase sPostn levels during early healing phase. The study aims to quantify the associations of sPostn levels with bone density loss and the possible effect on the fracture(More)
MIMO and relay technology is currently being promoted within the IEEE to enhance performance of broadband wireless standards such as WiMAX. However, due to licensed spectrum, it is necessary to implement highly efficient radio resource management. For optimal system design, it is beneficial to achieve higher system data throughput with fewer radio resources(More)
