The improvement of fiber-detection method to enhance the output of amplify-received relaying on FSO communications [PDF]
The performance of free-space optical (FSO) communications that using an optical amplifier (OA) in the scheme of an amplify-received (AR)-relaying has a major drawback in the detection of input signal quality under the effects of turbulence.

Composite scintillators based on ZnWO4:Me+ micropowders obtained by solid-state synthesis
The paper considers the possibility of using the method of heterovalent doping to improve the functional characteristics (light output and afterglow level) of composite scintillators based on ZnWO4 micropowder obtained by solid-stase synthesis.

Observations and modeling of scintillation in the vicinity of a polar cap patch
Small-scale ionospheric plasma structures can cause scintillation in radio signals passing through the ionosphere. The relationship between the scintillated signal and how plasma structuring develops is complex.

Climatology of GPS phase scintillation at northern high latitudes for the period from 2008 to 2013 [PDF]
Global positioning system scintillation and total electron content (TEC) data have been collected by ten specialized GPS Ionospheric Scintillation and TEC Monitors (GISTMs) of the Canadian High Arctic Ionospheric Network (CHAIN).

Indirect X-ray detectors with single-photon sensitivity
The new generation of synchrotron light sources are pushing X-ray detectors to their limits. Very demanding conditions with unprecedented flux and higher operating energies now require high-performance X-ray detectors combining sensitivity, efficiency ...

Scintillation Increase Induced by Focusing (Invited)
We show that the focusing of a random electromagnetic beam by a lens gives rise to a scintillation index at the geometrical focus that generally differs from that of the incident beam.

On the Relationship between Low Latitude Scintillation Onset and Sunset Terminator over Africa
The solar terminator is a moving boundary between day-side and night-side regions on the Earth, which is a substantial source of perturbations in the ionosphere. In the vicinity of the solar terminator, essential parameters like S4 index measurements are

Towards the possibility to combine LOFAR and GNSS measurements to sense ionospheric irregularities
Inhomogeneities within the ionospheric plasma density affect trans-ionospheric radio signals, causing radio wave scintillation in the amplitude and phase of the signals.
