We examined the diurnal pattern in Plasminogen Activator Inhibitor-type 1 (PAI-1) activity and Plasminogen activator (t-PA) in relation to the 4G/5G-polymorphism in the promoter of the PAI-1 gene. The analyses were performed in the Arnhem Elderly Study, a population-based study of 598 elderly. A single blood sample was drawn and the time of blood sampling was recorded (between 8 a.m. and 5.30 p...

This article presents an overview of the evolution of technologies, standards, and deployment from second to fifth generation mobile networks with emphasis on current and future trends in the areas of wireless networking, multimedia technology, network architecture, and network services. Related research in the development of future mobile systems has been highlighted. Issues of system integrat...

Fifth-generation (5G) cellular wireless networks are envisioned to predispose service-oriented, flexible, and spectrum/energy-efficient edge-to-core infrastructure, aiming to offer diverse smart-X (city, grid, and phones) applications. Convergence of software-defined networking (SDN), software-defined radio (SDR) compatible with multiple radio access technologies (RATs), and virtualization on t...

Current 4G air interfaces (AIs), by which we mean existing cellular standards and their evolution, including internetworking with other technologies such as WLAN, lack the flexibility required for support of multiple and diverse services envisaged for 5G, such as Massive Machine-Type Communications – mMTC, Ultra-reliable Machine-Type Communications – uMTC, and Extreme Mobile Broadband – xMBB, w...

Physical layer security which safeguards data confidentiality based on the information-theoretic approaches has received significant research interest recently. The key idea behind physical layer security is to utilize the intrinsic randomness of the transmission channel to guarantee the security in physical layer. The evolution towards 5G wireless communications poses new challenges for physic...

Abstract In order to meet the national intelligent development needs of coal mines, construct smart improve their safety production levels and finally realize vision flexible manpower line unmanned development, application 5G communication technology in seismographs for underground mines was discussed this study based on history advantages technology. Next, main scenarios were explored by combi...

Main focus in this paper is placed on demystifying the 5G paradigm from different aspects and view’s. From the beginning, from the time when the term 5G started to emerge in scientific circles it was unclear what exactly it represents. In the scientific community, there are many papers that are trying to present views of what they think 5G should be. In the past, several years it can be noticed...

The rapidly increasing number of mobile devices, voluminous data, and higher data rate are pushing to rethink the current generation of the cellular mobile communication. The next or fifth generation (5G) cellular networks are expected to meet high-end requirements. The 5G networks are broadly characterized by three unique features: ubiquitous connectivity, extremely low latency, and very high-...
