The initial wavelength and growth rate of aeolian dunes from a flat sand bed are well understood; aerodynamic theory developed for idealized conditions has recently been extended and successfully applied to predict dune formation in nature1,2,3. Once dunes grow large enough to perturb the flow ...
The angle of incidence is the angle between the line of sight and surface of the object you are looking for. The below figure shows the effect of the angle of an incident in Fresnel reflection. S and P Polarizations The plane which has the surface normal and the propagation vector of the...

The underwater topography of Toyama Bay is characterized by a narrow continental shelf that forms steep terrain within a few kilometers from the coast and reaches depths of 1000 m in the deep sea8. Many rivers flow into Toyama Bay, including the Oyabe River, Sho River, and Jintsu River o...
Radio propagation definitionRadio propagation is the way radio waves travel or propagate when they are transmitted from one point to another and affected by the medium in which they travel and in particular the way they propagate around the Earth in various parts of the atmosphere....
This type of result is well understood for scalar semilinear equations, such as the nonlinear Schrodinger equation (NLS) or nonlinear wave equation (NLW). The main new difficulties here are that (a) the wave maps equation is an overdetermined system, rather than a scalar equation, rendering suc...

Yet this can be explained for once it is understood that "workers’ power" and "soviet power" actually mean party power then the contradictions disappear. Party power had to be maintained at all costs, including the destruction of those who desired real soviet and workers’ power (and so ...
This can be understood in the usual sense – the x axis is the input and y axis is the output. Tracing a line from x to y, we find that once the lower threshold has been crossed, the hysteresis goes high and vice versa. The operation of the non-inverting comparator is similar – ...
(the electron’s antiparticle) is understood as being an electron moving backwards in time.Footnote8Moreover, virtual particles, existing in a meta-reality below the threshold of the uncertainty principle, are the drivers of the interactions in quantum field theory. See Fig. for an example of...
