Using high cadence observations from the Hydrogen-alpha Rapid Dynamics camera imaging system on Dunn Solar Telescope, we present an investigation of statistical properties transverse oscillations in spicules captured above solar limb. At five equally separated atmospheric heights, spanning approximately 4900-7500 km, have detected a total 15 959 individual wave events, with mean displacement am...

Euler's equations govern the behavior of gravity waves on surface an incompressible, inviscid, and irrotational fluid arbitrary depth. We investigate spectral stability sufficiently small-amplitude, one-dimensional Stokes waves, i.e., periodic permanent form constant velocity, in both finite infinite Using a nonlocal formulation developed by Ablowitz et al. (2006), we develop perturbation metho...

objectives: autism spectrum disorder (asd) is a group of neurodevelopment syndromes with impairments in social communications and restrictive or repetitive behaviors. neurofeedback is a new method that may regulate neuro and metabolic function in brain. this study is semi-experimental, with pre and post test.  methods: in 26 children with asd, 40 sessions of neurofeedback were done. brain waves...
