Unmanned Aircraft Systems (UAS) are increasing their communication subsystems complexity as they are using several data links both for redundancy and for tacking with different communication requirements: different ranges, bandwidth, power consumption or cost. Inside the airframe a similar tendency with respect to communications is appearing. Modern digital avionics are mainly implemented as di...

The millimeter-wave and THz frequency (f > 100 GHz) range remains one of the most underdeveloped frequency ranges, even though there are a great number of potential applications in remote sensing, spectroscopy, plasma diagnostics, and communications. This is because the millimeter wave and far-infrared frequency range falls between two other frequency ranges, the microwave frequency range and t...

A new series of 2-(6-alkoxynaphthalen-2-yl)-6-methoxyquinolines (nO-NpQOMe, n = 3-8) liquid crystal compounds, a linear molecular structure with two kinks, were synthesized using a short two-step reaction with overall yields between 43% and 58%. Spectral analyses were in accord with the expected structures. Thermotropic behavior of these liquid crystal compounds were investigated using polarize...

Recent single-molecule measurements have revealed the DNA allostery in protein/DNA binding. MD simulations showed that this allosteric effect is associated with the deformation properties of DNA. In this study, we used MD simulations to further investigate the mechanism of DNA structural correlation, its dependence on DNA sequence, and the chemical modification of the bases. Besides a random se...

In-band full-duplex (FD) communications have been optimistically promoted to improve the spectrum utilization and efficiency. However, the penetration of FD communications to the cellular networks domain is challenging due to the imposed uplink/downlink interference. This paper presents a tractable framework, based on stochastic geometry, to study FD communications in cellular networks. Particu...

Visible light communications achieve wireless using sources such as lighting fixtures and electric signboards. The need to blink at high speed avoid flickering. However, the blinking frequency is much higher than frame rate of general-purpose cameras that are integrated into consumer devices smartphones. This paper proposes a method where principle I/Q demodulator employed in radio used estimat...
