Mobile WiMAX is a rapidly growing broadband access technology based on IEEE 802.16 suite of standards. Supporting fast and seamless handover is a key requirement for the implementation of an efficient mobility framework in WiMAX systems. The IEEE 802.16 standard defines only the handover management framework but does not specify any specific handover(More)
Exposure to particulate air pollution is associated with increased cardiopulmonary morbidity and mortality, although the pathogenic mechanisms are poorly understood. We previously demonstrated that particulate matter (PM) exposure triggers massive oxidative stress in vascular endothelial cells (ECs), resulting in the loss of EC integrity and lung vascular(More)
Lung transplantation remains the only viable therapy for patients with end-stage lung disease. However, the full utilization of this strategy is severely compromised by a lack of donor lung availability. The vast majority of donor lungs available for transplantation are from individuals after brain death (BD). Unfortunately, the early autonomic storm that(More)
Various mixtures of barite (BaSO4) and celestine (SrSO4) powders were prepared and fused at a temperature of 1000C for 10 hours to form barium-strontium sulfate [BaxSr1-xSO4 (x=0 to 0.85)]. X-ray powder diffraction (XRD) data of the fused barium-strontium sulfate powders were measured using a powder diffractometer with a copper X-ray tube. The XRD data(More)
This paper proposes and devises a novel, simple, and cost effective PON-based 4G mobile backhaul RAN architecture that enables redistributing some of the intelligence currently centralized in the Mobile Packet Core (MPC) platform out into the access nodes of the RAN. Specifically, this work proposes and devises a fully distributed ring-based EPON(More)
A WiMAX TDD frame contains one downlink subframe and one uplink subframe, the capacity allocated to each subframe is a system parameter that should be determined based on the expected traffic conditions. Normally, the load in downlink is higher compared to uplink, hence the downlink subframe is expected to have a longer duration. The split between downlink(More)
In the mol-ecule of the title compound, C(7)H(8)NO(2) (+)·Cl(-)·H(2)O, an intra-molecular N-H⋯O hydrogen bond results in the formation of a non-planar six-membered ring adopting a flattened boat conformation. In the crystal structure, inter-molecular O-H⋯O and N-H⋯Cl hydrogen bonds link the mol-ecules. There is a C=O⋯π contact between the carbonyl unit and(More)
