A Compact Dual Bandpass Filter Using Dual Composite Right-/Left-Handed and Open-Loop Ring Resonators for 4G and 5G Applications [PDF]

Radioengineering
In this paper a very compact design of a dual-band band pass filter (D-BPF) using dual composite right-/left-handed (D-CRLH) and open-loop ring (OLR) resonators is presented. To overcome the frequency ratio limitations of D-CLRH resonators technique, the

The 4G/4G Genotype of PAI-1 Polymorphism Is Associated with Higher Plasma PAI-1 Concentrations and Mortality in Patients with Severe Sepsis.

PLoS ONE, 2015
ObjectiveTwo 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 ...

4G Technology

, 2016
Third generation (3G) mobile networks faces a new rival; so called 4G. An astonishingly new network may be even more profitable. The goal of 4G is to replace the current proliferation of core cellular networks, with a single worldwide cellular core network based on standard IP for control and media.

A Look Into the 4G Crystal Ball [PDF]

, 2006
The time for reflections and visions about the Fourth Generation of Wireless Mobile Communication Systems (4G) is getting closer to the X hour, therefore the research community has to finally declare how 4G will really look like. Besides the no-boundaries visions, in this paper we have a look into the 4G crystal ball, attempting to define the ...
