Super Lorentz vortex Gaussian beam (SLVGB) is propagated via the turbulent atmosphere parameters. The benefit key of SLVGB wave model that unlimited bandwidth and a spherical are involved. Additionally, Huygens Fresnel integral was used for schoolwork to study propagation in slant direction moderate medium. On other hand, applying crude international telecommunication union (ITU-R) possible. Mo...

A comprehensive statistical analysis was performed on Global Positioning System scintillation data acquired at high latitudes from 2014 to 2017 after separating phase events originating refraction and/or diffraction. Events exceeding a prescribed threshold were identified and analyzed statistically as function of time, latitude, propagation angle. The indicates that scintillation, which occurs ...

This paper presents intensity evolution of finite energy Airy Hermite Gaussian (FEAHG) beam and its scintillation performance under strong atmospheric conditions. Atmosphere is modeled utilizing split step propagation. Our results reveal that evolves into elliptic shape during Point like reduction obtained for all settings FEAHG beam. For selected apertures, less index provided by We think our ...

Comparison is carried out of the long term variation year averaged solar wind speed and interplanetary scintillation index with variations Wolf's numbers A_P indexes geomagnetic activity for data 20-24 cycles. It shown that slow non-monotonous trend in parameters at middle high heliolatitudes exists typical scale order century cycle. Correlation between anomalies air temperature analyzed series...

A method is described using Triton X-100 scintillant to simplify liquid scintillation counting of (55)Fe alone or in combination with (59)Fe. The Triton acts as an efficient solubilizing agent allowing small volumes of aqueous solutions of iron compounds in hydrochloric acid to be counted. The efficiencies achieved are comparable with those of previously described methods whilst the technique i...

The new Lcica RM 2165 automatic, heavy-duty microtome has an advanced step motor that permits an exact specimen feed and reproducible sectioning results. Features include 70 mm vertical stroke length, unique step trim function, and programmable specimen retraction. Technical features include a handwheel rocking sectioning mode; the motorized specimen feed can be linked to change the handwheel t...

Post-sunset disturbances in the equatorial ionosphere routinely cause rapid phase and amplitude fluctuations (i.e., scintillation) of radio waves propagating through the disturbed regions. The intensity of scintillations is positively correlated with the solar cycle and the associated signal fades will often exceed 20 dB at L-band frequencies during solar maximum. The effect of such an environm...

We introduce and analyze the first data from an array of closely spaced Global Positioning System (GPS) scintillation receivers established in the auroral zone in late 2013 to measure spatial and temporal variations in L band signals at 100-1000 m and subsecond scales. The seven receivers of the Scintillation Auroral GPS Array (SAGA) are sited at Poker Flat Research Range, Alaska. The receivers...
