We present recent studies on the impact of atmospheric turbulence on free-space links using either synchronous or nonsynchronous detection. We compare options for atmospheric compensation, including phase compensation and diversity combining techniques. We consider the effects of log-normal amplitude fluctuations and Gaussian phase fluctuations, in addition to local oscillator shot noise, for b...

We present a model for describing the combined presence of nematic and 'smectic' or stripe-like orders seen in recent scanning tunneling microscopy (STM) experiments on cuprates. The smectic order is treated as an electronic charge density wave with an associated Peierls distortion or a 'Pomeranchuk wave'. This primary order is restricted to nanoscale domains by disorder effects, while the seco...

We present a post-distortion linearization technique for semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) photonic sampler. The sampling source is an active mode-locked laser producing 12.6 ps-width pulses with repetition frequency of 10 GHz. mathematical model the presented and then evaluated quasi-static regime, i.e. continuous-wave signals, dynamic sinusoidal signals. A ...

One of the challenges in numerical simulation of wave–turbulence interaction is the precise setup and maintenance of wave and turbulence fields. In this paper, we investigate techniques for the generation and suppression of specific surface wave modes, the generation of turbulence in an inhomogeneous physical domain with a wavy boundary-fitted grid, and the generation and maintenance of waves a...

The purpose of the this research was investigate the comparison of risk taking and cognitive distortion of students with and without addiction tendency. This research was a case-comparative study. The population is consisted of all boy students of high school  in the city of  Bostanabad. The research participants is consisted of 200 students (100 students with addiction tendency and 100 student...

Abstract We have investigated the waveform distortion of energetic particle driven off-axis fishbone mode (OFM) in tokamak plasmas with kinetic magnetohydrodynamic (MHD) hybrid simulations. extended our previous simulations (Li et al 2022 Nucl. Fusion 62 026013) by considering higher-n harmonics MHD fluid, where n is toroidal number. The successfully reproduced simulation for both magnetic fluc...
