We consider the capacity of a band-limited additive white Gaussian noise channel, with bipolar inputs, a framework motivated by power-efficient faster than Nyquist signaling. We improve the available Ozarow-Wyner-Ziv (OWZ) lower bound on capacity by introducing a new communication scheme, exhibiting two advantages over the OWZ approach based on peak-power constrained pulse-amplitude modulation. We demonstrate analytically, a moderately improved information rate of the suggested technique, exhibiting also considerably less sign transitions of the bipolar signal. The gap between the known upper-bound based on spectral constrains of bipolar signals and the new achievable lower bound is reduced to 1.1 bits per Nyquist interval at the high signal-to-noise ratio regime.

Evaluation of myocardial function is critical in severe inflammations as myocarditis, COVID-19 and sepsis, since it can lead to organ failure and death. Point-of-care detection of myocardial injury may improve the treatment of these critically ill patients. The study aimed to develop point of care technology for assessing the systolic and diastolic cardiac functions in animal model of systemic inflammation. Ultrasound and ventricular pressure were continuously recorded in Langendorff perfused isolated adult rat hearts. A computer controlled system controlled the ventricle loading conditions. The preload of both ventricles swung in a sinusoidal manner between target values of 2 and 22 mmHg. Collagenase (MMP8) was added to the Krebs-Henseleit solution following baseline recordings, to emulate the release of MMPs from activated leukocytes and macrophages. Collagenase perfusion led to gradual decline in peak systolic pressure and decrease in the end-diastolic volume (EDV), that were associated with concentric myocardial wall thickening. Extracellular matrix degradation by collagenases caused sever diastolic dysfunction with overt shift of the end-diastolic volume toward lower volumes, without significant changes in the epicardial diameter. Early detection of these signs may assist in assessing the severity of the myocardial injury and prompt the adequate treatment.

In this paper, a design of a miniaturized microstrip quadrature 90° hybrid coupler using printed transmission lines and printed capacitors is presented. In order to perform the miniaturization process, the conventional quadrature 90° hybrid coupler planar arms are replaced with equivalent shorter ones which include printed capacitors in each junction of the component. The proposed coupler structure is designed to operate in the 24 GHz - 24.25 GHz band which is used for communication and radar systems. In this design, the main challenge in miniaturization was due to the coupling between the adjacent microstrip lines of the component. The proposed device area is 41% smaller compared to the conventional quadrature 90° hybrid coupler. The simulations were done using Ansys HFSS and Ansys Circuit software.

A balanced, series-fed linear horn array antenna containing 6 horn elements is proposed. The antenna is matched from 9.4 to 10.5 GHz for SWR = 2. The total height of the antenna is 70 mm, the directivity of the antenna is between 21.8 - 22.6 dBi, the total efficiency is –0.3 dB, with low cross-polarization.

The estimation of rain attenuation over a satellite link needs an accurate rainfall rate. The exponential development of satellite networks using higher-frequency bands such as Ka bands has highlighted the need to assess the combined effect of multiple diffusion impairments. The network of satellite communication links operating at Ku-band and above experiences rain fades due to signal absorption and dispersion. When considering link budget planning, the tropical and subtropical regions are of concern due to the high amount of precipitation when compared with the temperate regions. This paper examined the performance of the time-series ARIMA model on a Ka-band terrestrial link in Durban South Africa. The performance and validity are tested with the received signal level data measurements over a 6.73 km terrestrial LOS link centred at 19.5 GHz, the synthetic storm technique, and the International Telecommunication Union Recommendation model (ITU-R) based on rain attenuation generated from rain rate data over nine (9) years (20052013). The results reveal that the ITU-R model did not correspond with measured results. Hence, we tested a supervised learning-time series-based attenuation prediction method, which provides better performance than the existing models. Furthermore, the comparison with experimental results also shows that the proposed method has advantages of real-time forecast and high availability. The information from the present study will further provide quantitative insights on time-series rain fade needed in planning for 5G networks and beyond in the subtropical regions.

Public concern about potential health risks of radiofrequency electromagnetic field exposure (RF-EMF) from mobile networks and devices has ebbed and flowed over time with new claims and misinformation around 5G deployments. There remain misunderstandings about the nature and level of RF-EMF exposure from both mobile networks and devices. Measurements on live networks show that typical RF-EMF exposure levels from mobile networks and devices are a small fraction of international guidelines. 5G deployments will have little impact on RF-EMF levels. The consensus of independent expert groups and the World Health Organization is that there are no established health risks from such exposures.

In this paper a Y-band THz radiating CMOS source in the is presented. The source is based on a differential buffer- less Colpitts D-band VCO, which is tuned by controlling its gate- source capacitance through its transistor drain-gate voltage. The transistor drains are directly coupled to an on-chip loop antenna that chokes the fundamental signal while efficiently radiating the 3rd harmonic generated by the VCO transistor non-linearity. The source is locked using an external D-band source that radiates the CMOS chip and injection locks the source through its fundamental oscillation. The source can be tuned in a wide frequency range of 405 to 421 GHz with peak total output power of -15dBm (DC to THz radiated power efficiency of 0.1%), EIRP of -6 dBm and DC to EIRP power efficiency of 1.1%. This concept enables simple and cost-effective locked CMOS THz source arrays.

We show that the ballistic electron injection from the n+ source region through the i-region into the gated n-region of the n+-i-n-n+ graphene field-effect transistor (GFET) leads to the effective drag of quasi-equilibrium electrons toward the drain. The drag results in the positive feedback between the ballistic injection and the reverse injection from the n+ drain region and can lead to the negative real part of the GFET source-drain impedance accompanied with the change of the impedance imaginary part sign. As a result, the steady-state current flow along the GFET channel can be unstable giving rise to the current driven self-excitation of the electron density high-frequency oscillations (plasma instability). The related oscillations of the current feeding an antenna can be used for the terahertz radiation emission.

The fifth generation (5G) networks exhibit high data rates and capacities that endear them to applications such as internet of things (IoT) and mobile banking. Due to sensitivity of data exchanged in these applications, security and privacy preservation schemes are essential for their deployments. The Third Generation Partnership Project (3GPP) has specified evolved packet system authentication and key agreement (EPSAKA) and 5G AKA protocols for mutually authenticating the communicating entities. However, these protocols are vulnerable to attacks such as impersonation, denial of service (DoS), hijacking and packet replays. Consequently, other schemes based on technologies such as blockchain, public key cryptography and certificates have been introduced to counter these threats. Unfortunately, these algorithms have either high computation and communication overheads or fail to effectively prevent these attacks. In this paper, a new key agreement and authentication protocol is presented. Security evaluation shows that this protocol upholds backward and forward key secrecy, and is robust against attacks such as privileged insider and privacy violations. In terms of performance, it exhibits average computation overheads compared with other related schemes.
