This paper analyzes current standardization situation of 5G and the role network softwarization plays in order to address the challenges the new generation of mobile networks must face. This paper surveys recent documentation from the main stakeholders to pick out the use cases, scenarios and emerging vertical sectors that will be enabled by 5G technologies, and to identify future high-level se...
5G has to fulfil the requirements of ultra-dense, scalable, and customizable networks such as IoT while increasing spectrum and energy efficiency. Given the diversity of envisaged applications and scenarios, one crucial property for 5G New Radio (NR) is flexibility: flexible UL/DL allocation, bandwidths, or scalable transmission time interval, and most importantly operation at different frequen...
The ever increasing number of smart network devices may reach up to 24 billion in year 2020 as stated in the recent survey conducted by Forbes magazine. This may obsolete the current 4G technology for handling smart bandwidth allocation to such a large number of devices. In order to cope the challenging need for fast and efficient data transfer over these devices, demands next generation mobile...
OBJECTIVE Two studies have reported that patients with the 4G/4G genotype of the plasminogen activator inhibitor-1 (PAI-1) genetic polymorphism had higher plasma PAI-1 concentrations and higher risk of death than those with the 4G/5G or 5G/5G genotypes; one study involved 175 children with meningococcal disease, and the other included 88 adult patients with septic shock. Thus, the objective of ...
BACKGROUND The 4G/5G polymorphism of the plasminogen activator inhibitor-1 (PAI-1) gene has been related to cardiovascular disease. METHODS AND RESULTS Insulin resistance was measured with a frequently sampled intravenous glucose tolerance test in the Insulin Resistance Atherosclerosis Study (IRAS), and PAI-1 4G/5G promoter genotype was established by allele-specific polymerase chain reaction...
Introduction: A common polymorphism 4G/5G in the promoter region of the Plasminogen activator inhibitor-1 (PAI-1) gene has been reported to influence the expression levels of PAI-1. According to the evidence, progression of breast cancer can be associated with elevated levels of PAI-1, it seems that evaluation of a possible correlation between the polymorphism and clinical status of breast canc...
The 5G wireless communication system is a new generation mobile communication system beyond 2020. 5GNow is still in the exploration stage. There are some shortcomings in LTE and LTE-A, such as strict synchronism, latency in crowded areas, energy consumption, and challenging in IoT, etc. The 5G wireless networks is a will consider satisfying better user experience, manifoldness of services, M2M ...
Currently, many operators worldwide are deploying Long Term Evolution (LTE) to provide much faster access with lower latency and higher efficiency than its predecessors 3G and 3.5G. Meanwhile, the service rollout of LTE-Advanced, which is an evolution of LTE and a “true 4G” mobile broadband, is being underway to further enhance LTE performance. However, the anticipated challenges of the next de...
Activation of the renin-angiotensin-aldosterone system (RAAS) is associated with increased circulating PAI-1 antigen and increased risk of thrombotic cardiovascular events. A 4G/5G polymorphism located 675 bp upstream from the transcription start site of the PAI-1 gene affects PAI-1 antigen concentrations. To test the hypothesis that PAI-1 4G/5G genotype influences the effect of activation of t...
BACKGROUND The plasminogen activator inhibitor type-1 (PAI-1) has been implicated in the regulation of fibrinolysis and extracellular matrix components. The single base pair guanine insertion/deletion polymorphism (4G/5G) within the promoter region of the PAI-1 gene influences PAI-1 synthesis and may modulate hepatic fibrogenesis. AIM To evaluate the influence of PAI-1 serum levels and 4G/5G ...
